Description

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

Conventional technology Conventionally, this type of juicer was
As shown in Japanese Patent No. 51-25598, it had a structure as shown in FIG.

That is, a fixing plate 2 that can freely move to the left and right of the outer surface of a main body 1 containing a built-in motor (not shown) is attached, and the container 3 placed on the main body 1 is attached to the other side of the fixing plate 2 so that the container 3 is narrowly attached. The container 3 and container lid 4 are attached to the main body 1 by hooking them onto the protrusion 5 provided on the outside of the lid 4.
It was fixed on top. The left and right fixing plates 2 are connected to a connecting rod 6 inside the main body 1, and since this connecting rod 6 is pressed downward by a spring 7 inside the main body 1, the container lid 4 is fixed with the fixing plate 2. Then, the container 3 and the container lid 4 were fixed by receiving a force that brought them into close contact with the main body 1 side.

However, this time the inventors considered a different form of fixing the container lid and the main body. That is, as a prior art, we devised a structure in which the left and right sides of the container lid can be fixed on the main body by fitting into locking portions that project horizontally from the side walls of the main body. It is shown in Figure 4. Details will be described later. I will explain only the main points first.

In the figure, 12 is the main body, 23 is a container lid corresponding to the container lid 4 in FIG.
2 is a finger push part, 33 is a convex locking part sliding hole provided in the main body 12, 34 is a finger push part sliding hole of the finger push part 32, and 36 is a convex lock part provided in the container lid 23. The sliding hole 22 indicates a protrusion provided on the upper part of the main body 12.

The wavy line A indicates the state of engagement between the main body 12 and the container lid.

When the finger pressing part 32 is pushed inward in the engaged state shown by the wavy line A and the clamp 28 is deeply inserted into the main body 12 as shown in the figure, the convex locking part 31 and the finger pressing part 32 move into the convex locking part sliding hole 33. , the convex locking part 31 and the finger pressing part 32 contact the inner wall surface of the finger pressing part sliding hole 34, and the convex locking part 31 and the finger pressing part 32
There is a problem with not being able to go back outside.

Problems to be Solved by the Invention In order to fix the container lid to the main body with such a structure which is the prior art, the locking part protruding from the side wall of the main body is pressed by an elastic body from inside the main body, and the locking part is fixed to the main body. If an external force is applied from outside and the body is pushed inward, the locking part will be displaced to the inside of the main body, and when the external force is removed, the locking part must automatically return to the outside. There was a problem that if it went too deep, the locking part would shift from the locking part sliding hole of the main body and would not return to the outside of the main body.

Means for Solving the Problems The present invention provides a main body with a built-in electric motor, a container placed on the main body, and a container lid that covers the container, and a part of the opposite lower end of the container lid is turned downward. A locking hole is formed in the lid extension, and a clamp for supporting the bottom plate is provided in the main body, and a finger pressing part and a tip are provided in the middle part of the clamp. a convex locking portion protrudes outward from the main body, a finger press portion sliding hole is provided in the main body to allow the finger press portion to protrude, and the convex locking portion is configured integrally with the locking portion. engaging the hole and urging the clamp outwardly on the main body to join the main body and the container lid;
A plate spring is fixed thereto, which is integrally formed with a stopper portion that stops the convex locking portion of the clamp from moving inward when it comes off from the locking hole.

Function The present invention is capable of pushing the clamp outward when an external force is applied from the outside to the convex locking part that fits with the container lid, or a part of the clamp that protrudes outside the main body. The plate spring is displaced and the clamp moves toward the inside of the main body. However, when the convex locking part reaches the locking part sliding hole of the main body, a part of the plate spring that presses the clamp outward becomes a stopper that restricts the movement of the clamp inward into the main body. This prevents the clamp from penetrating deeply into the main body. This solves the problem of the clamp coming into contact with the end surface of the sliding hole of the main body and not moving smoothly.

Embodiment FIG. 1 is a sectional view of an embodiment of the electric juicer of the present invention, FIG. 2 is an exploded perspective view of the same main part, and FIG. 3 is an explanatory diagram of the operation of the same main part.

The configuration of the electric juicer of the present invention will be explained.

In FIG. 1, reference numeral 11 denotes a motor, which is fixed to the main body 12 via a buffer body 13 with screws 14. Reference numeral 15 denotes 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. 17 is centrifugal separation cage 16
It is a substantially cylindrical, comb-shaped filter that has a plurality of vertical slits that are removably attached to the inside. 1
8 is a cutter provided at the center bottom of the centrifugal separation cage 16, and 19 is a juice receiving container having a juice outlet 20 provided in a part of its lower part as shown in FIG. Reference numeral 21 denotes an elastic body provided in the grooves on the left and right sides of the back surface of the container 19. When the container 19 is attached to the main body 12, the center portion thereof comes into contact with the protrusion 22 on the top surface of the main body 12, and is pressed when the container 19 is pushed downward. It's getting old. Reference numeral 23 denotes a container lid that is detachably fitted to the container 19 and has a material input port 24 in the center. Reference numeral 25 is a push rod for pressing vegetables, fruits, etc. onto the cutter 18, and reference numeral 26 is a bottom plate that covers the lower surface of the main body 12 and has legs 27 attached thereto. Reference numeral 28 denotes clamps provided on the left and right sides inside the main body 12, whose position is regulated by the main body 12 and the bottom plate 26 with a slight play left in the vertical direction, and is pressed toward the outside of the main body 12 by a leaf spring 29 attached to the main body 12. There is. Further, the tip of the leaf spring 29 has a stopper portion 30 bent into an L-shape. The clamp 28 has a convex locking portion 31 at its upper end.
Further, a finger pressing portion 32 is provided below the finger pressing portion 32, and both of the finger pressing portions 32 protrude to the outside of the main body 12. 33 is the main body 12
34 is a finger-pressing part sliding hole provided in the main body 12. Reference numeral 35 denotes left and right lid extensions of the container lid 23, and a hole 36 that fits into the convex locking portion 31 of the clamp 28 is provided below.

The operation of the configuration of one embodiment of the electric juicer of the present invention will be described.

When the container lid 23 is attached after the container lid 23 is attached to the main body 12, the convex locking portion 31 at the upper end of the clamp 28 receives an inward force from the main body 12 at the lower end of the lid extension 35, and the plate spring 29 The convex locking portion 31 of the clamp 28, which had been pressed outward, is displaced inward to the main body 12, and when the hole 36 of the lid extension 35 reaches the convex locking portion 31, the clamp 28 releases the leaf spring 29. Since the clamp 28 is pressed outward, the convex locking portion 31 fits into the hole 36 and the container lid 23 is fixed to the main body 12. Next, main body 1
When separating the container lid 23 fixed to the main body 12 from the main body 12, press the finger push part 32 of the clamp 28 inward of the main body 12 with an external force, and the clamp 28 will separate from the main body 1.
2 is displaced inward, and the convex locking portion 31 engages the lid extension portion 3.
5, the container 19 rises above the main body 12 due to the repulsive force of the elastic body 21 provided on the back surface of the container 19 and compressed by the protrusion 22 on the top surface of the main body 12, and the container lid 23 also rises accordingly. , even if the external force applied to the finger pressing part 32 is removed,
The convex locking portion 31 no longer fits into the hole 36 of the lid extension 35, and the container lid 23 is lifted by hand to remove the main body 12.
can be separated more easily.

Here, the clamp 28 is attached to the main body 12 by inserting it from below the main body 12 with the bottom plate 26 removed.
When you press the convex locking part 31 or the finger pressing part 32,
This means that the convex locking part 31 and the finger pressing part 32 enter into the main body 12 from the inner walls of the convex locking part sliding hole 33 and the finger pressing part sliding hole 34 of the main body 12. Therefore, a stopper that does not penetrate deeply into the body 12 is required. Therefore, as in the present invention, the leaf spring 29
When the clamp 28 is pushed into the main body 12, one side of the stopper part 30 hits the boss 37 of the main body 12 and becomes a stopper for the clamp 28. In this manner, it is possible to prevent the convex locking portion 31 and the finger pressing portion 32 from penetrating deeper into the inner wall surfaces of the convex locking portion sliding hole 33 and finger pressing portion sliding hole 34 of the main body 12. Leaf spring 2
9 is not bent into an L-shape and there is no stopper part 30, the convex locking part 31 and the finger pressing part 32 are connected to the convex locking part sliding hole 33 of the main body 12, as shown in FIG. , from the inner wall surface of the finger pressing part sliding hole 34 to the main body 12
There is a problem that goes deep inside. By bending the tip of the leaf spring 29 into an L shape in this way,
The leaf spring 29 can serve two functions as a leaf spring that presses the clamp 28 outward and a stopper that restricts the movement of the clamp 28.

Effects of the Invention The present invention provides a plate spring inside the main body with one end fixed to press the clamp having a convex locking portion at the tip that projects outside the main body, and the plate spring has one end fixed inside the main body. The free end is bent into an L-shape and provided as a stopper part inward to the body, so one piece of leaf spring can be used as a leaf spring to press the clamp outward from the body, and as a stopper to restrict the movement of the clamp inward to the body. function, and allows the clamp to move smoothly.
