Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an extruder, and more
particularly to a food extruder to conveniently extrude semi-solid
food.
[0003] 2. Description of the Related Art
[0004] With reference to FIG. 5, a conventional food extruder (70)
in accordance with the prior art comprises a base and an extruding
device mounted on the base. With the conventional extruding device,
semi-solid food, such as ice cream or butter, is extruded from a
cylindrical container. However, the conventional food extruder (70)
is large and heavy and is usually securely mounted in a stationary
location. Moving the conventional food extruder for use in another
location is difficult. Therefore, the conventional food extruder
(70) is inconvenient to use.
[0005] To overcome the shortcomings, the present invention provides
a food extruder to mitigate or obviate the aforementioned
problems.
SUMMARY OF THE INVENTION
[0006] The main objective of the invention is to provide a food
extruder that is convenient to use. The food extruder has a body, a
holder, an extruding rod, a pressing plate and a driving device.
The body is hollow and has a handle extending from the body. The
holder is attached to the body and has a rear plate, a supporting
frame and a front plate. The rear plate is attached to the body.
The supporting frame has a U-shaped cross section and is connected
to the rear plate. The front plate is connected to the supporting
frame and has an extruding hole defined through it. The extruding
rod is slidable and extends through the body and into the holder.
The extruding rod has a first end extending into the holder and a
second end. The pressing plate is attached to the first end of the
extruding rod and is held inside the holder. The driving device is
mounted in the body and drives the extruding rod relative to the
body.
[0007] Other objectives, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
[0013] With reference to FIGS. 1 and 2, a food extruder (10) in
accordance with the present invention comprises a body (30), a
holder (50), an extruding rod (20), a pressing plate (21) and a
driving device (40).
[0014] The body (30) is hollow and has a handle (31), a chamber
(not numbered), two side plates (32,32a), a connector (36) and an
eye (35). The handle (31) is formed on and extends from the body
(30) to allow a user hold the food extruder (10). The chamber is
defined inside the body (30) to hold the driving device (40). The
two side plates (32,32a) are attached to the sides of the body (30)
with screws (34) to close the chamber. The connector (36) is formed
on one end of the body (30). The eye (35) is defined through the
body (30) to allow the food extruder (10) be hung on a hook or
attached to a strap.
[0015] The holder (50) is attached to the body (30) at the
connector (36) and comprises a rear plate (52), a supporting frame
(54) and a front plate (51). The rear plate (52) is attached to the
connector (36). The supporting frame (54) has a U-shaped cross
section and is integrally attached to the rear plate (52) at one
end. The front plate (51) is integrally attached to the other end
of the supporting frame (54), is aligned with the rear plate (52)
and has an extruding hole (53) defined through it.
[0016] The extruding rod (20) is slidable and extends through the
body (30) and into the holder (50). The extruding rod (20) has a
first end extending into the holder (50) and a second end extending
out of the opposite end of the body (30).
[0017] The pressing plate (21) is attached to the first end of the
extruding rod (20) and is held inside the holder (50). A knob (23)
is attached to the second end of the extruding rod (20), such that
a user can move the extruding rod (20) outwards from the body (30)
by pulling on the knob (23).
[0018] The driving device (40) is mounted inside the body (30) to
drive the extruding rod (20) relative to the body (30). The driving
device (40) comprises a driving plate (44), a trigger (41), a
resilient member (45), a brake (47) and a biasing member (46). The
driving plate (44) is mounted inside the body (30) around the
extruding rod (20) at an inclined angle. The driving plate (44) has
a through hole with a diameter slightly larger than that of the
extruding rod (20) and through which the extruding rod (20)
extends. The trigger (41) is pivotally attached to the body (30)
with a pivot (42) and has an inner end and an outer end. The inner
end is held inside the body (30), and a pin (43) is attached to the
inner end and abuts the driving plate (44). The outer end extends
out of the body (30). The resilient member (45) is mounted inside
the body (30) around the extruding rod (20), may be a spring, and
abuts the driving plate (44). The brake (47) is mounted inside the
body (30) around the extruding rod (20) at an inclined angle and
engages the extruding rod (20) to keep the extruding rod (20) from
moving outwards from the body (30). The brake (47) has an extension
(48) extending out of the body (30). The brake (47) has a through
hole with a diameter slightly larger than that of the extruding rod
(20) and through which the extruding rod (20) extends. The biasing
member (46) is mounted inside the body (30) around the extruding
rod (20) and abuts the brake (47).
[0019] With reference to FIGS. 3 to 5, in operation the extension
(48) on the brake (47) is pressed to disengage the brake (47) from
the extruding rod (20). The user can then pull the extruding rod
(20) out with the knob (23) to move the pressing plate (21) toward
the rear plate (52) of the holder (50). A cylindrical container
(60) containing semi-solid food is put inside the holder (50)
between the rear plate (52) and the front plate (51) and is held by
the supporting frame (54). The cylindrical container (60) has an
outlet (63) defined in one end of the cylindrical container (60)
and aligned with the extruding hole (53) in the front plate (51).
An opening is defined in the other end of the cylindrical container
(60) and faces the pressing plate (21) to allow the pressing plate
(21) to enter the cylindrical container (60) through the
opening.
[0020] When the trigger (41) is pulled, the pin (43) on the trigger
(41) will push against the driving plate (44) to move it forward
and toward the holder (50). With the inclined angle of the driving
plate (44), the through hole in the driving plate (44) securely
engages the extruding rod (20). Consequently, the extruding rod
(20) is driven toward the holder (50) by the driving plate (44),
such that the pressing plate (21) will press food in the
cylindrical container (60) to extrude out of the cylindrical
container (60) from the outlet (63) in the cylindrical container
(60) and the extruding hole (53) in the front plate (51). When the
user releases the force applied to the trigger (41), the driving
plate (44) will be pushed to tilt slightly relative to the body
(30) by the resilient member (45) and disengage from the extruding
rod (44). The driving plate (44) is moved back to its original
position by the resilient force provided by the resilient member
(45) and engages the extruding rod (20) again. The trigger (41) is
also pivoted to its original position by the movement of the
driving plate (44). Accordingly, the user can pull the trigger (41)
again to extrude more food out from the cylindrical container (60).
After the food is completely extruded from the cylindrical
container (60), the extruding rod (20) can pulled back to draw the
pressing plate (21) out of the cylindrical container (60) when the
extension (48) on the brake (47) is pushed.
[0021] In such an arrangement, the food extruder (10) in accordance
with the present invention has a simplified structure, is manually
operated and is convenient to use and carry to any desired
location.
[0022] Even though numerous characteristics and advantages of the
present invention have been set forth in the foregoing description,
together with details of the structure and function of the
invention, the disclosure is illustrative only. Changes may be made
in the details, especially in matters of shape, size, and
arrangement of parts within the principles of the invention to the
full extent indicated by the broad general meaning of the terms in
which the appended claims are expressed.
