DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an electric juicer for squeezing juice from vegetables and fruits.

Conventional technology A conventional lever of this kind is, for example, the
As shown in Publication No. 25598, it looked like Figure 7.

That is, a fixing plate 2 is attached to the outer surface of the main body 1 on which the container 3 and the container lid 4 are placed, and is pivoted at one end and moves freely, and the other end of the fixing plate 2 is attached to a protrusion 5 provided on the outside of the container lid 4. container 3 and container lid 4.
was fixed on the main body 1.

Problems to be Solved by the Invention However, with such a structure, after placing the container 3 and the container lid 4 on the main body 1, the fixing plate 2 is rotated by an external force and the other of the fixing plates 2 is attached to the protrusion 5. Since the container 3 and container lid 4 must be hung on the main body 1, the fixing plate 2 is rotated.
It required two movements and was very troublesome. Furthermore, since the fixing plate 2 protrudes widely from the outer surface of the main body 1, it is difficult to make the entire product compact.

Therefore, the present invention provides that, after placing the container and container lid on the main body, by lightly pressing the top surface of the container lid downward, the container and container lid are automatically and easily fixed to the main body, and the fixed container lid can also be easily removed. In addition, the protrusion of the fixing plate from the main body can be reduced to make the product more compact.

Means for Solving the Problems In order to solve the above problems, the juicer of the present invention includes a main body incorporating an electric motor, a container placed on the main body, a container lid that covers the upper part of the container, and a container lid that covers the top of the container. A clamp that is provided inside the main body and has a locking part that partially slopes so that the upper surface thereof is lowered outwardly and that extends through the side wall of the main body and faces outside the main body; a spring that urges the clamp to protrude outward; and a hole into which the locking part is inserted into the container lid facing the locking part; This structure includes an elastic body that acts in the vertical direction.

Effect The effect of this technical means is as follows. In other words, when a container lid is attached after a container etc. is mounted on the main body, the lower end of the container lid first hits the upper surface of the locking part of the clamp, and is pressed by an elastic body to apply a component force in the direction inside the main body to the locking part. The clamp that was previously attached is displaced inward. When the container lid is further pressed downward and the hole in the container lid reaches the position of the locking part, the clamp pressed by the elastic body is displaced outward and the locking part of the clamp fits into the hole in the container lid. , the container lid is fixed to the main body. Next, when separating the fixed container lid from the main body, press the clamp that protrudes outside the main body to the inside of the main body, and move the locking part of the clamp to the inside of the hole in the container lid, so that the back of the container that was compressed Since the elastic body pushes up the container and the container lid, the locking part of the clamp does not fit into the hole even if the clamp is stopped pressing inward, so the container lid can be easily lifted and removed.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In Figures 1 to 6, 11 is the main body 1.
A motor is attached to the lower part of 2 with a screw 14 via a buffer 13, and 15 is an output shaft connected to the rotating shaft of the motor 11, and a substantially cylindrical centrifugal separation cage 16 is detachably attached to the upper end of the output shaft. has been done.
17 is a substantially cylindrical comb-shaped filter that is detachably installed inside the centrifugal separation cage 16; 18 is a cutter provided at the center bottom of the centrifugal separation cage 16; and 19 is a juice receiving container placed on the main body 12. A youth outlet 20 is provided in a part of the lower part. Reference numeral 21 denotes a container lid which is detachably fitted into the youth receiving container 19 and has a material input port 22 in the center. Reference numeral 23 designates a push rod that is inserted into the material input port and presses vegetables, fruits, etc. onto the cutter 18, and 24 designates a bottom plate that covers the lower surface of the main body 12 and has legs 25 attached thereto. 26 is a plate-shaped clamp whose lower end is supported by fixing parts 34 provided on both sides of the inner bottom of the main body 12;
The upper part is always urged toward the outside of the main body 12 by a spring 27. A locking portion 28 having an inclined upper surface is provided at the upper end of the clamp 26, and a finger pressing portion 29 is provided below the locking portion 28, both of which protrude outward from the main body 12. 30 is a lid extension extending downward from the container lid 21, and is provided with a hole 31 that fits into the locking portion 28 of the clamp 26. 33 is a protrusion provided on the upper surface of the main body 12 above the clamp 26, and a leaf spring 32 is provided on the back surface of the container 19 opposite to this protrusion 33.
is provided.

Next, the operation of the configuration of this embodiment will be explained. First, a centrifuge cage 16 and a container 19 are placed on the main body 12.
etc., and then attach the container lid 21, the lid extension part 3
0 comes into contact with the locking portion 28 of the clamp 26. After that, when the container lid 21 is pressed downward, the fourth
As shown in the figure, the clamp 26 pressed by the spring 27 receives a force inward from the main body 12 at the locking portion 28, so that the clamp 26 is displaced inward from the main body 12. When the container lid 21 is further pressed and the hole 31 provided in the lid extension 30 reaches the position of the locking portion 28 of the clamp 26, the locking portion 28 is fitted into the hole 31 by the force of the spring 27. Then, the container lid 21 is fixed to the main body 12 as shown in FIG. 1 because the clamp 26 is vertically regulated by the main body 12 and the fixing part 34 in advance. That is, the container lid 21 is attached to the main body 12,
The container lid 21 can be fixed to the main body 12 with a single action of pressing downward. Also, container lid 2
When the container 19 is pushed downward, the container 19 also moves downward, so when the container lid 21 is fixed to the main body 12, the container 19
Since the plate spring 32 provided on the back surface of the container 19 is pressed by the protrusion 33 on the top surface of the main body 12, the container 19 and the container lid 21 are in close contact with each other. Therefore, clamp 2
Even if there is a slight gap in the vertical direction between the locking part 28 of 6 and the hole 31 of the lid extension part 30, the container 19 and the container lid 21
Since there is no rattling between the main body 12, not only no chattering noise is generated due to vibration, but also leakage of waste from the outer contact portion of the container 19 and the container lid 21 can be prevented. Next, when separating the container lid 21 fixed on the main body 12, the finger pressing part 29 of the clamp 26 is pressed inside the main body 12 with a finger, and the locking part 28 is moved inside the hole 31 of the lid extension part 30. When the container 19 and the container lid 21 are moved upward due to the elasticity of the pressed leaf spring 32 on the lower surface of the container 19, the locking portion 28 remains even when the finger pressing the finger pressing portion 29 of the clamp 26 is released. Since the container lid 21 does not fit into the hole 31, it is easy to lift the container lid 21 by hand and remove the container lid 2.
1 can be separated from the main body.

Effects of the Invention As is clear from the description of the above embodiments, the juicer of the present invention is provided with a clamp in the main body whose locking portion is biased so as to protrude toward the outer surface of the main body, and the clamp is locked to the container lid. In addition to providing a hole that fits into the container, an elastic body that acts in the vertical direction is provided on at least one of the surfaces where the container and the main body come into contact, making it easy to attach and detach the container and the main body. There is no play between the container, the container lid, and the main body, and it is possible to prevent chattering noise and leakage of waste from the contact area between the container and the container lid.
