Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the protection scope of the present invention.

A juice machine with an autonomous circulation filtering function and a method of using the juice machine according to a preferred embodiment of the present invention is shown in Figures 1-7. The juice machine includes a container 1 for holding fruits and vegetables, and is provided at the bottom of the container 1 for cutting the fruits and vegetables. The broken rotary cutter 2, the filter bucket 3 for filtering the mixed juice containing chopped fruits and vegetables in the container 1, and the return pipe 4 for returning the juice in the container 1 to the filter bucket 3 for filtering; the filter bucket 3 The lower end is located in the container 1. Generally, the filter barrel 3 can be located in the container 1 as a whole or a part of the lower end is located in the container 1. It only needs to ensure that the opening 3a at the upper end faces upward. Furthermore, the upper and lower sides of the return pipe 4 The two ends are respectively formed into a juice outlet end 4a and a juice inlet end 4b for introducing juice into the filter barrel 3. The rotary cutter 2 is eccentrically provided with a press-in portion 5 for flowing juice into the juice inlet end 4b. When the juice machine is started, the rotary cutter 2 rotates. , the rotating cutter 2 forms a certain pressure on the juice so that it is discharged towards the surroundings and then enters the juice inlet end 4b, and the filter barrel 3 is provided with a liquid inlet 6 corresponding to the outlet of the return pipe 4. Since the juice is subject to continuous pressure, the juice is The return pipe 4 is pressed into the filter barrel 3, and the pressure-in part 5, the return pipe 4, and the special filter barrel 3 cooperate with each other to effectively and significantly reduce the content of solid particles such as residues and cores in the vegetable and fruit juices, satisfying the user's requirements for fruits and vegetables. The demand for drinking juice can also prevent the juice discharge valve on the container 1 from being blocked. When the assembly is in place and the filter barrel 3 is inserted into the container 1, the outer wall of the filter barrel 3 is along the juice outlet end 4a. Move downward to ensure that the distance between the juice outlet end 4a and the filter barrel 3 is small enough to ensure that as much of the backflow juice enters the filter barrel 3 as possible. Of course, the filter barrel 3 and the juice outlet end 4a can also be non-adjacent. The setting method uses the flow inertia of the juice to enter the liquid inlet 6, but this method is not very effective. In addition, the structural design of the filter barrel 3 of this solution can have multiple functions. On the one hand, it plays the role of preliminary filtration, and on the other hand, After the juice is squeezed and filtered, the user takes out the filter bucket 3, and can use a pressing rod or a spoon to extend into the filter bucket 3 to squeeze out the juice contained in the vegetable and fruit residue and flow it back into the container 1 through the hole mesh of the filter bucket 3. The function of secondary re-filtration. Furthermore, when the juice machine is cutting fruits and vegetables in the early stage, the fruits and vegetables on the upper layer need to be squeezed downwards to be chopped faster and more completely. The special structure of the filter barrel 3 of this solution can With this function, you only need to select a suitable setting position on the container 1, and it can be used to squeeze the fruits and vegetables toward the rotating knife 2, speeding up the juicer's crushing and juice extraction speed, enriching the product functions of the juicer, and improving the user's use Experience.

Preferably, the container 1 is provided with a fixing hole 7 adapted to the filter barrel 3. When assembled in place, the upper end of the filter barrel 3 is located outside the container 1 to facilitate the removal or insertion of the filter barrel 3, and also to facilitate the user to view the filter barrel at all times. The accumulated amount of fruit and vegetable residues within 3 hours can be removed and processed in time.

Preferably, the container 1 includes an open container 1a, and a container top cover 1b that covers the opening of the open container 1a; a fixing hole 7 is provided on the container top cover 1b, and the filter barrel 3 can be removed and disposed in the fixing hole 7. Specifically, the filter barrel 3 slides with the inner wall of the fixed hole 7 to facilitate the user to insert or remove the container 1 at any time. Furthermore, in order to prevent the lower end of the filter barrel 3 from colliding with the rotating cutter 2, a filter barrel is provided on the upper end of the side wall of the filter barrel 3. There is a boss 8 to snap onto the top cover 1b of the container. In addition, in order to prevent the juice from overflowing the top cover 1b of the container along the gap between the fixed hole 7 and the filter barrel 3 during the juice filtration process, the top cover of the container is The inner wall of 1b is provided with an anti-overflow cofferdam 9 surrounding the fixed opening. At the same time, the anti-overflow cofferdam 9 can also play a role in stabilizing the filter barrel 3, and can also serve as a suitable guide for the filter barrel 3 when it is moved in and out. role

Preferably, the juice machine also includes a squeeze rod 10 inserted into the filter barrel 3 to squeeze the fruit residue inside, which plays the role of secondary re-filtration to avoid the juice contained in the fruit and vegetable residues from being wasted. Specifically, During actual production and manufacturing, the filter barrel 3, the rotating cutter 2 and the container top cover 1b are all coaxially arranged.

Preferably, this solution preferably adopts a design that prevents the juice outlet 4a from being adjacent to the outer wall of the filter barrel 3, so as to provide convenient space for the positioning of the return pipe 4 and the rotating cutter 2, and ensure that the overall structure of the juice machine is reasonable and To be more optimized, further, the filter barrel 3 is provided with a juice-receiving bridge 11 that matches the juice outlet 4a and the liquid inlet 6 to ensure that the juice flowing out of the juice outlet 4a can enter the inside of the filter barrel 3. The juice-receiving bridge 11 is generally It is a long strip plate with a guide groove 12 to ensure the efficiency of filtration. Among them, the horizontally opposite side walls of the liquid inlet 6 are provided with rotating shafts 13 for longitudinal rotation of the juice bridge 11. When squeezing, When the rod 10 is located outside the filter bucket 3, that is, before the extrusion rod 10 is inserted or inserted into the filter bucket 3 but has not yet contacted the juice-receiving bridge 11, the juice-receiving bridge 11 remains in a position to guide the juice flowing out of the juice outlet end 4a. In the tilted state of the liquid port 6, when the extrusion rod 10 is inserted into the filter barrel 3, the lower end of the juice-receiving bridge 11 is pressed down by the extrusion rod 10, thereby causing the juice-receiving bridge 11 to form a vertical shape stored in the liquid inlet 6. state, the two states of the juice receiving bridge 11 can prevent the user from taking out the filter barrel 3 when he forgets to insert the squeeze rod 10. The bridge 11 will be stuck on the bottom surface of the container top cover 1b, making it impossible for the user to further take out the filter barrel 3, thereby reminding the user to insert the squeeze rod 10, preventing juice with heavy fruit and vegetable residues from being wasted, and also preventing the user from Taking out the filter barrel 3 directly will cause the juice to drip on the table or the ground.

Among them, the normal maintenance of the tilted state of the juice-receiving bridge 11 can be achieved by providing a torsion spring on the rotating shaft 13. Of course, it can also be achieved in other ways, such as arranging the rotating shaft 13 in the middle of the juice-receiving bridge 11 close to it. The position of the lower end makes the juice-receiving bridge 11 form a top-heavy structure. In order to prevent the upper end of the juice-receiving bridge 11 from tilting toward the inside of the filter barrel 3, a counterweight 14 can be provided on the upper end of the lower surface of the juice-receiving bridge 11. Alternatively, a blocking member or other structure may be provided on the filter barrel 3 to prevent the upper end of the juice connecting bridge 11 from being inclined toward the inside of the filter barrel 3. Furthermore, the port of the juice outlet 4a is inclined downward toward the liquid inlet 6, that is, the end face of the port is inclined downward. Toward the liquid inlet 6, in order to achieve practical effect and avoid rusting of the torsion spring, this plan adopts a method of improving the structure of the juice bridge 11 to maintain the above-mentioned tilted state, that is, arranging a configuration on the outer wall of the juice bridge 11 , and in order to further optimize the structure, the guide groove 12 on the juice connecting bridge 11 is formed by bending the juice connecting bridge 11 itself in a wavy shape along the axial direction of the two rotating shafts 13, that is, the cross section of the juice connecting bridge 11 is in the shape of a triangle, and The convex side wall forms the above-mentioned counterweight 14, and the concave side forms the guide groove 12. The two rotating shafts 13 are arranged at both ends of the digit-shaped structure. When the rotating shaft 13 is arranged at both ends of the digit-shaped structure, After reaching the lower end position, the juice-receiving bridge 11 will become tilted due to the uneven weight distribution between the upper end and the lower end. Further, a support base 15 is provided on the juice-receiving bridge 11 to maintain its tilted state to prevent the upper end of the juice-receiving bridge 11 from falling. Continuing to descend causes the distance between it and the juice outlet end 4a to be too large, which in turn causes only a small part of the juice in the return pipe 4 to enter the filter barrel 3. When the juice connecting bridge 11 is in an inclined state, the upper end of the juice connecting bridge 11 and the juice outlet end The ports of 4a are close to each other, and the port of the juice outlet is connected to the upper end of the juice bridge to form a blocking position. Together with the support base 15, it can prevent the user from pulling out the filter barrel 3 when the squeeze rod 10 is not inserted. The support base 15 is connected with the inlet. The inner walls of the lower end of the liquid port 6 are offset to ensure that the juice connecting bridge 11 can guide all the refluxed juice into the liquid inlet 6 and into the filter barrel 3.

In addition, in order to facilitate the use of the support base 15 to maintain the tilted state of the juice receiving bridge 11, the side wall of the filter barrel 3 where the liquid inlet 6 is located protrudes outward, so that the lower end side wall of the liquid inlet 6 forms a support platform 16. When the juice bridge 11 performs the diversion action, the support base 15 leans on the support platform 16. Of course, for the sake of beauty and practicality, the outer contour of the juice bridge 11 is the same as the outer contour of the liquid inlet 6 and they are adapted so that When the juice connecting bridge 11 is in the vertical state, the liquid inlet 6 is completely closed.

Preferably, the extrusion rod 10 is in the shape of a barrel that matches the inner cavity of the filter barrel 3 for ease of use and ensures that after the extrusion rod 10 is inserted into the filter bucket 3, the bottom surface of the extrusion rod 10 can completely cover the filter bucket 3. The fruit and vegetable residues inside are fully squeezed, and the hollow structure can reduce costs and weight.

Preferably, when assembled in place, the return pipe 4 is attached to the inner wall of the container 1, and the lower end side wall of the return pipe 4 is provided with a gap 17 corresponding to the press-in part 5 to facilitate the entry of juice.

Preferably, the press-in part 5 is a vertically arranged blade. The blade is generally arranged on the lowermost blade of the rotating tool 2 and is integrally arranged to facilitate processing and manufacturing while also ensuring firmness. Furthermore, the blade is away from the rotating tool 2 One end of the rotating shaft 13 forms an acute angle with the inner wall of the container 1 along the rotation direction to facilitate the flow of juice into the return pipe 4 .

The method of using the juice machine with autonomous circulation filtering function according to the preferred embodiment of the present invention is as shown in Figure 8. The method includes the following steps:

S10 Put the fruits and vegetables into the container 1 and start the juice machine to chop and squeeze the juice through the rotating end knife, and wait for the juice machine to run for the first preset time to ensure that the fruits and vegetables are chopped. The first preset time is determined by the user according to his own settings. It is set according to the requirements and is not limited here;

S20: After the juice machine has run for the first preset time period, place the return pipe 4 corresponding to the filter barrel 3 into the container 1 so that the juice outlet 4a is directly opposite to the liquid inlet 6. Through the rotating rotary cutter 2 and the pressing part 5 With the cooperation, the juice will flow into the return pipe 4 and into the filter barrel 3, and wait for the juice machine to run for the second preset time to ensure that the vegetable and fruit residues are thoroughly filtered. The second preset time is set by the user according to their own needs. , no limitation is made here;

S30: After the juice machine has run for the second preset time period, take out the filter barrel 3. Bin further inserts the squeeze rod 10 into the filter barrel 3 to squeeze out the juice contained in the fruit and vegetable residues, which further facilitates the throwing away or disposal of the fruit and vegetable residues. for other purposes.
