Detailed ways

Referring to FIGS. 1 to 7 , a side slag discharge structure of a juicer of the present invention includes a cup body 1 , and a juice outlet 1a and a slag outlet 1b are arranged on the cup body 1 . The filter 2 is disassembled and connected. The specific structure of the filter is not the technical point to be protected by the present invention. The integrated structure of the plastic parts disclosed in the present invention will not be repeated here. A matched screw 3 is rotatably connected in the filter 2, a squeeze gap 4 is formed between the screw 3 and the filter 2, a juice outlet 5 is formed between the filter 2 and the cup body 1, and the lower side of the filter 2 is formed. The wall is provided with a slag passage hole 2a which is opposite to the slag outlet 1b and leads to the extrusion gap 4 .

A first sealing rubber ring 6 is detachably connected to the bottom of the filter 2, a second sealing rubber ring 7 is integrally formed on the outer edge of the first sealing rubber ring 6, and the second sealing rubber ring 7 is sandwiched at the periphery of the slag outlet 1b Between the cup body 1 and the filter 2, a sealing film 7a is integrally formed in the inner hole of the second sealing rubber ring 7, which is matched with the slag hole 2a. In the initial state, the sealing film 7a seals the outlet of the slag hole 2a. When the slag is discharged, the pomace squeezes out the sealing film 7a and enters the slag outlet 1b.

By cleverly arranging the second sealing ring, a sealed communication channel is built for the slag passing hole and the slag outlet in the juice outlet channel 5. While realizing the side slag discharge, the simple structure of the cup body is maintained, and there is no need for the slag outlet in the cup body. A complex structure is set up to realize the separation of juice residue. At the same time, the slag outlet and the juice outlet are basically located on the same plane, which effectively solves the disadvantage that the juice flows out of the slag outlet. In the prior art, an isolation ring is set at the lower part of the cup body, and then a slag outlet is set at the bottom of the isolation ring, and the juice outlet is located at the upper part of the isolation ring, which causes the juice to enter the lower part of the isolation ring when the juice is first squeezed or when the juice is full. The juice will flow out from the slag outlet, which will seriously affect the juice yield of the machine.

The structure of the connection and positioning portion can be specifically set as required, as long as the first sealing rubber ring can be easily disassembled and assembled. In this embodiment, the connecting and positioning portion is an annular shape with an L-shaped cross-section on the right side, and a corresponding annular connecting groove with an L-shaped cross-section is formed in the first sealing rubber ring.

The outer wall of the lower end of the screw 3 is integrally formed with a positioning ring 3a, and a pressure ring 2c matched with the positioning ring 3a is arranged at the bottom of the filter 2. When the screw 3 is idling, the lower end of the screw 3 does not contact the inner bottom surface of the cup body 1. The positioning of the lower end of the screw is realized by the cooperation of the pressing ring and the positioning ring. At the same time, through the arrangement of the first sealing rubber ring, the contact between the screw and the filter and the bottom of the cup body during rotation is avoided, so as to avoid wear and prolong the service life.

Further, in order to facilitate the installation of the first sealing rubber ring and ensure the accurate position of the second sealing rubber ring, a foolproof structure is provided between the second sealing rubber ring 7 and the filter 2 .

In the present embodiment, the foolproof structure includes a sealing surface 8 integrally formed on the outer wall of the filter 2 corresponding to the outlet end of the slag passage hole 2a and matched with the second sealing rubber ring 7.

The second sealing rubber ring 7 is tightly attached to the sealing surface 8 at the lower end of the positioning convex strip 8b. On the second sealing rubber ring 7, there is a vacancy gap 7b adapted to the positioning projection 8a. The upper end of the sealing rubber 7a is connected with the second sealing rubber ring 7 and is adapted to the inner contour of the positioning projection strip 8b. Of course, the sealing film and the second sealing rubber ring can also be connected at other positions, for example, the upper end or the left end or the right end of the sealing film is connected with the second sealing rubber ring. The purpose of the sealing film and the second sealing rubber ring is to prevent the sealing film from falling off and to automatically reset and seal the slag hole under the action of its own elasticity. When the connection position of the sealing film and the second sealing rubber ring is changed, the shape of the positioning projection will also be changed accordingly, which is an equivalent alternative solution that can easily be thought of by those skilled in the art.

Of course, based on the disclosure of the above foolproof structure, those skilled in the art can also adopt other conventional foolproof structures matched with concave-convex structures, all of which should be regarded as equivalent replacements.

Further preferably, the outer surface of the second sealing rubber ring 7 is integrally formed with an inverted U-shaped sealing protruding strip 7c, and the free end of the sealing protruding strip 7c extends to the lower end of the side surface of the first sealing rubber ring 6; the second sealing rubber The ring 7 is in contact and sealed with the inner wall of the cup body 1 through the sealing protruding strip 7c. By setting the sealing protruding strip, the contact between the second sealing rubber ring and the inner wall of the cup during installation is reduced, so as to avoid displacement due to excessive contact between the second sealing rubber ring and the inner wall of the cup when the filter is installed, which will affect the sealing properties and use effects.

In this embodiment, the first sealing rubber ring and the second sealing rubber ring can be made of conventional food-grade and elastic materials in the art, such as silica gel, TPR (thermoplastic rubber material).

The above-mentioned embodiments are the preferred embodiments of the present invention, and are only used to facilitate the description of the present invention, and are not intended to limit the present invention in any form. Within the scope of the technical features mentioned in the utility model, the equivalent embodiments that utilize the technical contents disclosed in the present utility model to make partial changes or modifications, and do not depart from the technical feature contents of the present utility model, still belong to the technical features of the present utility model.
