Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates to a jet propeller for air-charging,
and an outboard motor having the same, and particularly to a jet
propeller for air-charging, which, in addition to the propelling
function, can be coupled with special function nozzle device in
order to use the same apparatus achieving the following functions:
air-charging, air pumping, as a spray gun, high-pressure water
spray (fire fighting or cleaning), and water pumping, and an
outboard motor having the jet propeller for air-charging.
[0003] 2. Description of the Prior Art
[0004] The ships advance with the engine and the propeller, but the
cavitation of the propeller often cause the propeller into idle
operation and the ship speed is thus slow down. According to the
"Bernoulli theorem", the faster the rotation speed of the propeller
is, the smaller the pressure of the water flow will be, and the
water flow will evaporate. When the surface pressure of the blade
of the propeller becomes lower than the vapor pressure of the sea
water, a phenomenon of "propeller cavitation" is generated. The
bubbles generated by the blades are the main cause for the
vibration and acoustic noise of a ship. Serious burst of the
bubbles will decrease the efficiency of the propeller, make the
propeller into idle operation, and slow down the ship speed, and
even gear-shaped spots will turn up on the blade of the propeller
and damage the propeller.
[0005] Meanwhile, when a traditional propeller propulsor is in
rotation, a resistance force face and a drag force face are
generated behind the blade, slowing down the ship speed. The size
of the blade of the propeller will not only be related to the
amount of propelling force, but also form the resistance force face
and the drag force face, a part of ship speed is thus eliminated.
Additionally, the propeller is easily wrapped around and collided
by miscellaneous objects in the water, thereby easily damaging the
propeller.
[0006] Although the spiral propeller blade structure of the
conventional International Patent Publication EP0334737 "Rotary
non-positive machine" enhances the water flow and improves the
generated resistance force and drag force, it is still a
propeller-blade structure, all inferior phenomena due to the
abovementioned "Bernoulli theorem" are not overcome.
[0007] Nowadays, the main improvement in more advanced jet
propulsors is to install the traditional propeller propulsor in the
interior of a tube. By installing the propeller in the interior of
a tube, the resistance force and the drag force generated by the
propeller are therefore minimized, and the propelling speed is
thereby increased. However, the jet propulsor still uses a
propeller which is easily wrapped around by miscellaneous objects,
inferior phenomena due to the "Bernoulli theorem" cannot be
overcome, and the problem of the resistance force and the drag
force is still not solved completely. A jet propulsor cannot use a
longer tube, a larger pressure is thus not generated to increase
the propulsion performance.
[0008] Conventional Taiwan Patents 572842, 547573, 528699, 339756
and USA patents US005181868A and US005083435A have disclosed
propulsors having different functions in different ways, but these
patents still use propellers, the problems of the abovementioned
prior art are therefore not solved.
[0009] Furthermore, the prior art of the present invention from
Taiwan Patent No. I,296599 provides a beam jet propeller (USA
patent U.S. Pat. No. 7,497,657B2), which increases the friction
force of the fluid by spiral or linear diversion protrusions or
diversion grooves on the inner wall of a tube, such that original
loose fluid can be twisted together into a beam shape under
pressure/rotation/extrusion and form in-tube fluid pressure. The
beam fluid may generate a strong propelling force, so as to propel
the vehicle.
[0010] However, the abovementioned patents only provide the
propelling functions without other additional functions. If the
vehicle using the roller propeller is an inflated vehicle, the
propeller may be employed as an inflating apparatus, and also be
employed as a propeller after inflation. Thus, the propeller may
achieve both the environmental protection and convenience effect
under repetitive usage. Besides, the vehicle after inflation has a
certain buoyancy, the gas inside the vehicle can be pumped out
during idle operation to reduce the volume and weight; moreover,
providing the fire fighting, cleaning and water pumping functions
only by replacing the nozzle. Therefore, it is a problem needed to
be rapidly solved in the industry about how to design a
multi-functional propeller.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0059] Please refer to FIG. 1, which is a diagram of a jet
propeller for air-charging according to the present invention. The
jet propeller 210 according to the present invention comprises: a
first diversion structure for pressurizing an in-tube fluid; a
roller-type diversion tube 220, which has a second diversion
structure inside the roller-type diversion tube 220 for further
pressurizing the in-tube fluid pressurized by the first diversion
structure; and, a shaft 240 for driving the first diversion
structure and the second diversion structure to rotate, such that
the in-tube fluid will be pressurized by the rotation of the first
diversion structure and the roller-type diversion tube 220 to form
the in-tube fluid pressure for generating the propelling force.
[0060] As shown, the jet propeller 210 according to the present
invention further comprises a water inlet pipe 234, a first
diversion structure, a roller-type diversion tube 220 and a shaft
240, which is configured inside the water inlet pipe 234, and the
first diversion structure is a fluid pressurizing diversion
protrusion 232, and the second diversion structure is at least one
or a plurality of spiral diversion protrusions 222.
[0061] In this embodiment, the jet propeller 210 according to the
present invention is basically a structure as a roller-type jet
propeller 210. When the fluid flows through a rotating roller-type
jet propeller 210, the fluid will first enter the water inlet pipe
234 (non-rotating) through a water inlet 230; then, the fluid will
first go through the rotation of the fluid pressurizing diversion
protrusion 232 within the tube, and the in-tube fluid will generate
the fluid pressurizing phenomenon due to the pressure difference
relation between the front and the rear side generated after
rotation; then, the pressurized fluid starts entering the rotating
roller diversion tube 220 within the water inlet pipe 234. The
fluid pressurizing diversion protrusion 232 is located at the
portion of the shaft 240 protruding from the roller diversion tube
220, such that the flow speed of the fluid entering the roller
diversion tube 220 is increased to enhance the efficiency of the
propeller. The fluid pressurizing diversion protrusion 232 cannot
be too close to the roller diversion tube 220, otherwise it will
cause the chaos in the flow field. Thus, the optimized length of
distance between the fluid pressurizing protrusion 232 configured
in the front of the shaft 240 and the roller diversion tube is
approximately the length of diameter of the fluid pressurizing
diversion protrusion 232.
[0062] With the rotational speed along with the shaft 240 inside
the roller diversion tube 220, the spiral diversion protrusion 222
will further pressurize the fluid after pressurization, and the
fluid will start generating flow rotation from the front to the
back and accelerating motion. Because the pitch of the spiral
diversion protrusion 222 employs the design of parallel type or
front-wide-rear-narrow type, when the fluid is rotating in the
roller-type jet propeller 210, the fluid in the roller diversion
tube 220 will gradually generate a pressure difference between the
front and the rear side, so that the pressurized fluid will move
toward the opening at the tail end. When the pressure difference in
the tube is larger than the pressure outside the roller diversion
tube 220, the fluid in the tube will eject outwardly from the tail
end of the roller diversion tube 220 and generate the fluid
propelling force, and further form a reaction propelling force.
Moreover, the spiral diversion protrusion 222 on the roller
diversion tube 220 inside the jet propeller 210 can also be
replaced with a propeller, so as to achieve the requirement for
different propelling forces in design and in use. The tail end of
the roller-type jet propeller 210 can also be connected with a
coupling tube pressurizing device 360 and a special function nozzle
device 280 for usage as air-charging, fluid suction, water pumping,
air jet or water jet. (Please refer to FIG. 3 and FIG. 4)
[0063] Furthermore, in this embodiment, the jet propeller 210
according to the present invention, based on the designed structure
in the figure, can be suitable for applying in high-, mid-, and
low-speed (such as electric engine, internal combustion engine)
power device 310. The generated propelling force is about 1-30
knots/hour, which is suitable for mid- and low-rotational-speed
power device used in an aquatic vehicle, such as canoe, skiff,
pneumatic boat, snorkeling vehicle, and diving machine. This figure
is only an illustration of an embodiment, so that the usage is not
only limited to aquatic or underwater vehicle, and can be applied
in other applications, such as fluid power device, fluid engine,
etc.

air-charging, and can be used to produce the aquatic vehicle, such
as PVC, rubber, composite leather, reinforced plastic material,
wiredrawing glassfiber, etc. which is characterized that the
vehicle after air-charging is provided with a certain buoyancy, so

the aquatic vehicle. The present invention is preferred to be
applied in an electric motor. If the aquatic vehicle needs larger
power, the present invention can also employ various types of
internal combustion engine, turbo engine, etc., to meet with the
power energy requirement in actual application; the power source of
the jet propeller 210 is the power device 310 in the present
invention, which is an innovative propeller design. The propeller
breaks through the method using the conventional propeller as the
propelling force, but employs a design of parallel tube roller or a
hollow tube roller with a hollow space tapered from one end to the
other end. The roller diversion tube 220 has at least one spiral
diversion protrusion 222 therein. When the roller diversion tube
220 is rolling, by the tangent flow of the spiral diversion
protrusion 222 inside the roller diversion tube 220 and the fluid
(air or water) motion mode with pressure difference between the
front and the rear side generated by unequal pitch, the fluid will
generate pressure in the middle and at the rear end of the roller
diversion tube 220. After the roller diversion tube 220 kept
continuously rotating, the spiral diversion protrusions 222 inside
the roller diversion tube 220 will greatly increase the pressure of
the fluid rolling in the roller generated during tangent flow. When
the fluid pressure inside the roller diversion tube 220 is
gradually larger than the external pressure of the roller diversion
tube 220, it will generate the propelling force and ejecting
outwardly, so as to generate a reaction propelling force. Such a
propelling force is sufficient for driving the inflated vehicle
device 110 according to the present invention or non-inflated
vehicle device; and, any product being able to replace the spiral
diversion protrusions 222 inside the roller diversion tube 220,
such as a propeller, can thus generate a powerful propelling force,
eject air 465 or water column 255 as a spray or a column (referring
to FIG. 6 and FIG. 7), which is also available to have such a
function without the present invention.
[0065] In the present invention and those embodiments, the fluid is
generally indicating any flowing air, dirty gas, chemical gas,
mixture gas, water, liquid, viscous liquid, glue, agent, and
chemical liquid, etc.
[0066] In this embodiment, a power device 310 is installed at a
suitable location on the inflated vehicle device 110, so as to
generate a certain kinetic energy to drive the roller-type jet
propeller 210, and further generate the propelling force to let the
inflated vehicle device 110 move forward.

rotate, and sucking the fluid external to the propeller device 122
into the water inlet pipe 234; then, after the rotation of fluid
pressurizing diversion protrusion device 232 (inside the water
inlet pipe 234), the fluid inside the water inlet pipe 220 will
generate the pressurized fluid into the roller 220; at this time,
the rotating spiral diversion protrusion 222 (or propeller) in the
roller diversion tube 220 will further pressurize the fluid after
pressurization to gradually increase the fluid pressure inside the
roller diversion tube 220; once the pressure in the roller
diversion tube 220 is larger than the external pressure, the fluid
will be ejected outwardly and generate the reaction propelling
force, so that the attached vehicle 305 will move forward.
[0097] Please refer to FIG. 10, which is an outboard engine with
differential gear according to the present invention. In the
embodiment, the outboard engine 740 with differential gear
according to the present invention is almost the same as FIG. 9 in
structural design. The only difference is to add a differential
gear device 875 inside the power device 310, which may increase or
reduce the original rotational speed of the motor 325 to be
compliant with the propelling force requirement of various vehicles
305.
[0098] Because the components, connection, operation and functions
recorded in the embodiment have been described in FIG. 7, there is
no need for description herein. Please refer to FIG. 7 if
needed.
[0099] Please refer to FIG. 11, which is an outboard engine with
universal joint according to the present invention. In the
embodiment, the outboard engine 760 with universal joint according
to the present invention is almost the same as FIG. 10 in
structural design. The only difference is that there are additional
one universal joint 330 and a power device (shaft 215) inside the
power device 310 in addition to the original differential gear
device 875, so as to change the original horizontal rotation mode
to be compliant with the space and propelling force requirement of
various vehicles 305.
[0100] Because the components, connection, operation and functions
recorded in the embodiment have been described in FIG. 9 and FIG.
10, there is no need for description herein.
[0101] Please refer to FIG. 12, which is a cross-sectional diagram
for speed distribution in fluid simulation test according to the
present invention. In the embodiment, the cross-sectional diagram
for speed distribution in fluid simulation test according to the
present invention is based on the fluid speed distribution of the
beam jet propellor 210 during operation according to the present
invention, as shown in FIG. 1. The fluid simulation test was
conducted by United Ship Design & Development Center in Taiwan.
Please refer to the color diagram as attachment 1. It is clear that
the fluid speed distribution of the jet propeller 210 according to
the present invention during propelling can be proved to have
effective propelling performance. Please refer to FIG. 13, which is
a pressure distribution diagram of the diversion protrusion in the
fluid simulation test according to the present invention. In the
embodiment, the fluid simulation test was conducted by United Ship
Design & Development Center in Taiwan. Please refer to the
color diagram as attachment 2. It is clear that the color
distribution at the front end and the rear end of the fluid
pressurizing diversion protrusion 232 according to the present
invention is located at two ends of the color code table (such as
Red and Blue). It is obvious that the pressure difference between
the front end and the rear end of the fluid pressurizing diversion
protrusion 232 is very large, so that the flow speed of the fluid
entering the roller diversion tube is increased, and further
enhancing the efficiency of the propeller.
[0102] After describing preferred embodiments of the present
invention in detail, it is clearly understood to those skilled in
the art that all kinds of alterations and changes can be made
within the spirit and scope of the appended claims. Therefore, the
spirit and scope of the appended claims should not be limited to
the implementation of the preferred embodiments contained in the
specification.
