DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] Referring to FIG. 1 and FIG. 2, the present invention is
composed of following:
[0016] a dust container (10) with a machinery plate (11) on top to
install a vacuum motor (12); the machinery plate (11) has a cover
(13) on top to protect all the equipments inside; a hose connector
(14) is on one side of the dust container (10);
[0017] a hose set, as shown in FIG. 1 and FIG. 2, is further
composed of a hose (15) and at least one hose turning tube (16)
made of hard material with definite length and turning angle; one
end of the hose (15) is plugged into the hose connector (14)
moveably;
[0018] a nozzle (20), as shown in FIG. 2, FIG. 3 and FIG. 4, with a
dust inlet (21), (22) each on the front and end, a flute (211),
(221) is formed along the open of the dust inlet (21), (22) to
increase the vacuum clean area; the dust inlet (21), (22) connect
to the nozzle hose connector (23) through internal path inside the
nozzle (20), the nozzle hose connector (23) moveably connects to
the hose turning tube (16); several wheel (24) are installed on the
sides of the bottom of the nozzle (20) so that the nozzle (20) can
roll on the floor.
[0019] Based on the structure described above, users can activate
the vacuum motor (12); dust and small particles are sucked in from
the dust inlet (21), (22) of the nozzle (20), pass through the hose
(15) and the hose turning tube (16) finally reaches the dust
container (10). The present invention consists of a steam
mechanism; the steam mechanism consists of following:
[0020] a steam generator generates high temperature steam; two
applications of the present invention are described below.
Referring to FIG. 1 and FIG. 2, the steam generator (30) of the
first application is installed on the machinery plate (11); the
steam generator (30) further composes of a water tank (31) with a
water inlet on top, the water inlet has a threaded water inlet
cover (321), the water inlet cover (321) exposes outer the cover
(13) for users to add cleaner or water; a heater (33) is under the
water tank (31) to heat the fluid in the water tank (31) to
generate high temperature steam; a steam outlet tube (34) is on
near the top of the water tank (31) for the high temperature steam
to go out. Referring to FIG. 5 and FIG. 6, the steam generator (40)
of the second application is installed external to the main body;
the main body of the vacuum cleaner described above is on top of a
main base (41), the steam generator (40) is installed on the other
side of the main base (41). The steam generator (40) has a water
tank (42) on the main base (41), fluid is filled from top of the
water inlet; a water outlet tube (43) is on the bottom of the water
tank (42), the water outlet tube (43) can connect to a water pump
(not shown in FIG) to press water into a heater (44) inside the
main base (41), the heater (44) heats up the injected fluid into
high temperature steam and output the high temperature steam
through a steam outlet tube (45). The steam generator (30) of the
first application boils the water in the water tank (31) to
generate steam, users have to wait for a period of time until the
water to heat up for steam cleaning function; users also have to
wait till all the water is consumed before more water to fill in.
The steam generator (40) of the second application continuously has
water injected from the water tank (42) into the heater (44); the
steam is generated in no time and continuously, users can fill
water anytime to have the steam all the time;
[0021] a steam conveying structure is to send steam from the steam
outlet tube (34), (45) to the nozzle (20), the structure has two
types: external and internal. The external type (as shown in FIG.
2) is to have the steam outlet tube (34) run along the hose (15)
and the hose turning tube (16) externally to the steam tube
connector (25) on the nozzle (20). The internal type (as shown in
FIG. 5, FIG. 6 and FIG. 7) is to have the steam outlet tube (45)
insert into and go along inside the hose (15), the end of the steam
outlet tube (45) passes through the hose (15) and connects to the
steam tube connector (25);
[0022] a steam output structure (as shown in FIG. 2, FIG. 3 and
FIG. 4), is to have a steam tube connector (25) on the nozzle (20)
for the steam outlet tube (34), (45) to connect; several steam
spout (26) are on the bottom center of the nozzle (20), the steam
spout (26) are connected to the steam tube connector (25) with the
internal channel of the nozzle (20); two floor scraper (27), (28)
are installed on two sides of the steam spout (26) on the bottom of
the nozzle (20), the floor scraper (27), (28) can be in blade shape
as shown in FIG. 3 or in brush shape as shown in FIG. 4.
[0023] Users can, activate the steam device, the steam generator
(30), (40) heats up water or cleaner into high temperature steam,
the high temperature steam is output from the steam outlet tube
(34), (45) and pressed through the steam tube connector (25) on the
nozzle (20), finally injected out from the steam spout (26).
[0024] The external type steam outlet tube (34) is fixed to the
hose (15) and the hose turning tube (16) with several band
(50).
[0025] The internal type steam conveying structure includes:
[0026] an "L" shape connector (51) (as shown in FIG. 6, FIG. 7) is
installed on the end of the hose (15) where the hose (15) is
inserted into the dust container (10). An orientation piece (511)
with curve shape can fix the whole structure onto the hose (15)
internally; a thread section (512) stretching out of the hose (15)
is beneath the orientation piece (511); a connector (513) is on top
of the structure stretching toward the hose (15), the connector
(513) connects to a internal steam tube (451) inside the hose
(15).
[0027] a fixed nut (52) is designated to attache to the end of the
steam outlet tube (45); the fixed nut (52) has a holder (521) on
one end bent inward;
[0028] a connecting tube (53) with at least one ring (531) on
surface for the steam outlet tube (45) to wrap around, a holding
ring (532) is on one end of the connecting tube (53) to hold the
steam outlet tube (45) from coming out; the fixed nut (52) wraps
the connecting tube (53), the holder (521) reaches and is stopped
by the ring (531), the fixed nut (52) is then turned and locked
into the thread section (512) of the "L" shape connector (51), the
fixed nut (52) and the internal steam tube (451) is fixed firmly
together. The internal steam tube (451) extends inside the hose
(15) and connects to the external steam outlet tube (45') with the
"L" shape connector (51) at the end; the external steam outlet tube
(45') stretches along the hose turning tube (16) and connects to
the steam tube connector (25) of the nozzle (20).
[0029] The function of steam mechanism and vacuum cleaner are
described below:
[0030] when steam vapor is generated, users can turn on vacuum
motor (12) for cleaning.
[0031] Users can push the nozzle (20) on the floor back and forth
to have the dust inlet (21), (22) inhale dust on floor; at the same
time, the injected high temperature steam from steam spout (26) can
soft and loose the stubborn stain, the stain along with the
condensed water is sucked by the dust inlet (21), (22), the high
temperature -steam also has sterilization function. The floor
scraper (27), (28) also helps remove the stubborn dirt.
[0032] The floor scraper (27), (28) not only help remove the
stubborn stain, they also isolate the steam spout (26) from the
dust inlet (21), (22) to prevent the steam from inhaling by the
dust inlet (21), (22) when the steam is just injected from the
steam spout (26) to let steam has more time to function.
[0033] While a preferred embodiment of the invention has been shown
and described in detail, it will be readily understood and
appreciated that numerous omissions, changes and additions may be
made without departing from the spirit and scope of the
invention.
