Description

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

BACKGROUND OF THE INVENTION Conventionally, this type of juicer has been used, for example, in
As shown in Japanese Patent No. 5598, it had a structure as shown in FIG.

That is, a fixing plate (2) that moves freely to the left and right of the outer surface of the main body (11) containing a built-in motor (not shown) is attached, and the other of the fixing plates (2) is placed on the main body (1). container(
The container (3) and the container lid (4) were fixed on the main body (1) by being hooked onto a protrusion (5) provided on the outside of the container lid (4) so as to sandwich the container (3) and the container lid (4). Then, install the left and right fixing plates (2
) is connected to a connecting rod (6) within the main body (11), and this connecting rod (6) is pushed downward by a spring (7) within the main body (11).
Since it is under pressure, when the container lid (4) is fixed with the fixing plate (2), the container (3) and the container lid (4) will be fixed by receiving the force of coming into close contact with the main body (1) side. It had become.

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, u is the main body, @ is the container lid corresponding to the container lid (4) in Figure 5, (c) is the bottom plate, (c) is the clamp body,
Ge is the leaf spring, Gυ is the convex locking part, 0 is the finger pressing part, (to)
(b) is the sliding hole of the finger pressing part C33, and (to) is the sliding hole of the convex locking part provided on the container lid (c). The moving hole (company) indicates the protrusion provided on the upper part of the main body.

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

When the finger press part 03 is pushed inward in the engagement shape of IIA and the clamp (C) is deeply inserted into the main body α as shown in the figure, the convex locking part Gυ and the finger press part 03 engage in the convex shape. Stop sliding hole (
), there is a problem in that the convex locking portion Gυ and the finger press C33 do not return to the outside of the main body α2 due to contact with the inner wall surface of the finger press sliding hole (b).

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. If it goes too deep, there is a problem that the locking part will shift from the locking part sliding hole of the main body and will 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 supported by the bottom plate is provided in the main body, and a finger pressing part is provided in the middle of the clamp. A convex locking portion is integrally formed at the tip of the main body and projects outward, and the main body includes a stopper portion at the tip of the main body that urges the clamp outward and stops the clamp from moving inward beyond a certain distance. A leaf spring having a shape of The main body and container lid are joined together.

Function The present invention provides a plate that presses the clamp outward when an external force is applied from the outside to the convex locking portion that fits with the container lid, or the part of the clamp that protrudes outside the main body. The shaped 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 Figure 1, αυ is a motor, and a buffer body 0 is attached to the main body α.
It is fixed with screws I through the floor. α9 is an output shaft connected to the rotating shaft of the motor αυ, and a substantially cylindrical centrifugal separation basket (l[9) is detachably attached to the upper end of the output shaft.

αη is a substantially cylindrical, comb-shaped filter having a plurality of vertical slits that is detachably mounted inside the centrifugal separation basket αe. The α barrel is a cutter installed at the center bottom of the centrifugal separation basket αe, and the sen is a juice receiving container with a second
As shown in the figure, a juice outlet is provided. Qυ
is an elastic body provided in the grooves on the left and right sides of the back of the container handle.
When the container α is attached to the main body α2, its center portion comes into contact with the protrusion (to) on the upper surface of the main body α2, and is pressed when the container α is pushed downward. @ is a container lid that detachably fits into the container a1 and has a material input port @ in the center. (c)
is a push rod that pushes vegetables, fruits, etc. onto the cutter αe.
The hood is a bottom plate that covers the lower surface of the main body a and has a leg hood attached.

(to) are clamps installed on the left and right inside the main body σ2,
The position is regulated by the main body (13) and the bottom plate (E) with a slight play left in the vertical direction, and the leaf spring (C) attached to the main body (2) pushes the main body α outward. The tip of the clamp (c) has a horizontal part bent into an L shape.The clamp (c) has a convex locking part Oυ at its upper end and a finger press part 3 below it. (To) is a sliding hole for the convex locking part provided on the main body az, and (B) is a sliding hole for the finger pressing part provided on the main body Q7J. ( The left and right lid extensions of the container lid are provided with holes below which are fitted with the convex locking portions Gυ of the clamps.

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

After installing everything other than the container lid (to) on the main body α2, attach the container lid (c)
When attached, the convex locking part Gυ at the upper end of the clamp (to) receives an inward component of the force at the lower end of the lid extension (to), and the clamp is pressed outward by the plate spring (c). (2
) is displaced inward to the main body α2, and when the hole (to) of the lid extension (to) reaches the convex locking part 0υ, the clamp (c) is pressed by the leaf spring. As a result, the clamp (end) is displaced outward, and the convex locking portion Gυ bottoms into the hole (end), and the container lid (end) is fixed to the main body α.

Next, in order to separate the container lid (c) fixed on the body 0 from the body α, when the finger pushing part Oz of the clamp (to) is pushed inward by an external force, the clamp (to) will be separated from the main body α. When the convex locking part Gυ comes out of the hole (to) of the lid extension part (g), the elasticity that has been compressed by the protrusion (to) on the top surface of the main body 02 provided on the back of the container handle is displaced inward. The repulsive force of the body QD causes the container al to rise above the main body α side, and the container lid (c) also rises accordingly, so even if the external force applied to the finger pressing part Oa is removed, the convex locking part Gυ will not hold the lid. It no longer fits into the hole (to) of the extension (c), and the container lid (c) can be lifted by hand and separated from the main body.

Here, the clamp (to) is inserted from below the main body a with the bottom plate (c) removed and attached to the main body α2, but this is similar to the clamp (c) attached to the main body α.
the main body (12 from the outside, the convex locking part GI of the clamp (c)
When you press l or the finger press part (to), the convex locking part 0υ and the finger press part 03 move into the convex lock part sliding hole (to) and the finger press part sliding hole (b) on the main body α. It means entering the body @ from the inner wall surface. Therefore, a stopper that does not penetrate deeply into the main body az is required. Therefore, if the tip of the leaf spring (to) is bent into an L-shape and a horizontal part (7) is provided as in the present invention, when the clamp (c) is pushed into the main body α2, one side of the horizontal part (to) az boss C37) and clamp it (
As shown in Fig. 3, the convex locking part 0υ and the finger pressing part G3 serve as a stopper for the convex locking part sliding hole (to) of the main body α2.
, it is possible to prevent the finger pressing portion from penetrating deeper than the inner wall surface of the sliding hole (2). Horizontal part (to) without bending the leaf spring crest into an L shape
If there is no convex locking part c3υ, the finger press part (2) is inserted into the convex lock part sliding hole of the main body α2), and the finger press part sliding hole as shown in Figure 4. There is a problem that it penetrates deeper into the inside of the main body than the inner wall surface of (to). By bending the tip of the leaf spring (to) into an L-shape in this way, the leaf spring W is assembled into a single part that presses the clamp (c) outward and a stopper that restricts the movement of the clamp (c). It can fulfill two functions.

Effects of the Invention The present invention provides a plate spring having one end fixed therein, which presses a clamp having a convex locking portion at its tip that projects outside the main body in the direction outside the main body. In order to use the free end as a horizontal part that becomes a stopper horizontally in the direction of the main body, it is a leaf spring component that presses the clamp outward from the main body, and also as a stopper that restricts the movement of the clamp in the direction of the main body. can fulfill the function of
This allows the clamp to move smoothly.
