Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of juice extractor filter, in particular to a multi-stage filter structure of juice extractor. BACKGROUND

[0002] Juice extractor is a machine that can quickly squeeze fruit and vegetable into juice, and it can process vegetables and fruits into sweet drinks, which is always loved by people. With the improvement of people's living standards, juice extractors have gone from beverage stores to kitchens of millions of households and become a necessary helper for people to improve their living style.

[0003] The juice extractor in the prior art usually installs a filter structure at the outlet for filtering residues, but the filter structure is usually composed of only one filter screen. In order to ensure the filtering accuracy, the mesh size of the filter screen must be set to the minimum value required, so that residues of different sizes are all accumulated in one filter screen for filtering, which affects the filtering speed.

[0004] The above information disclosed in the background section is only used to strengthen the understanding of the background of the present disclosure, so it can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0005] The purpose of the present application is to design a multi-stage filter structure to filter residues of different sizes in sequence, so as to avoid the situation that residues of different sizes are all accumulated in one filter screen for filtering, which affects the filtering speed, in order to solve the above problems in the art.

[0006] In order to achieve the above purpose, the present application provides the following technical scheme: a multi-stage filter structure of juice extractor, comprising an outer cover detachably connected with the output end of the juice extractor, the outer cover has a plurality of filter covers arranged in linear array inside, the plurality of filter covers are connected end to end, and the top of the uppermost filter cover is attached to the top of the outer cover, the filter cover has a filter cavity with an upward opening, the filtering accuracy of the plurality of filter covers increases gradually from top to bottom, and a buckle member is slidably installed on the outer cover, the buckle member buckles the plurality of filter covers in the outer cover.

[0007] The filter covers with different filtering accuracy are buckled in the outer cover by the buckle member, so that the filter structure has different filtering accuracy as required.

[0008] Preferably, the filter cover comprises a top ring, a hollow tube fixedly connected to the bottom of the top ring, and a filter screen fixedly connected to the bottom of the inner cavity of the hollow tube, and the hollow part between the hollow tube and the filter screen forms the filter cavity.

[0009] Preferably, the cross section of the hollow tube is set as a U-shaped, and the outer periphery of the top ring and the inner periphery of the bottom of the hollow tube have the same diameter.

[0010] Preferably, the volume of the filtering chambers in the plurality of filtering covers gradually decreases from top to bottom.

[0011] Preferably, the mesh size of the filtering screens in the plurality of filtering covers gradually decreases from top to bottom.

[0012] Preferably, the outer circumferential surface of the hollow tube is further fixedly connected with a plurality of rib rings, the buckle member comprises a plurality of buckle strips penetrating through the outer cover and slidably connected with the outer cover, a connecting plate fixedly connected with one side of the plurality of buckle strips, and a spring fixedly connected between the connecting plate and the outer cover, when the top surfaces of the plurality of buckle strips are attached to the bottom surfaces of the plurality of rib rings, the top ring on the lower filtering cover is inserted into the bottom of the hollow tube of the upper filtering cover.

[0013] Preferably, the bottom of the buckle strip near one end of the hollow tube is chamfered.

[0014] Preferably, the side of the connecting plate away from the outer cover is further fixedly connected with a pull ring.

[0015] In the above technical solution, the present application provides technical effects and advantages:

[0016] 1. When the product filters the juice and residues squeezed by the juicer, the residues are sequentially filtered from top to bottom, so that the same layer filters residues of different thicknesses, avoiding all residues being accumulated in one filtering screen to affect the filtering speed.

[0017] 2. When the product removes the residues in different filtering covers, the filtering cover can be removed from the outer cover by pulling the buckle member to the two sides, so that the residues in the upwardly open filtering chamber in the filtering cover are cleaned, and the operation is convenient.

[0018] 3. The product can also select filtering covers with different precision according to the needs in the outer cover, so as to have the function of different filtering precision. BRIEF DESCRIPTION OF DRAWINGS

[0028] The present application provides a multi-stage filtering structure of a juicer as shown in Figures 1-4

[0029] The user moves the filter cover 2 with the largest hole of the filter screen 2c to the bottom of the outer cover 1, and then pushes the filter cover 2 upwards, so that the top ring 2a on the filter cover 2 is inserted into the top of the inner cavity of the outer cover 1, and the hollow tube 2b on the filter cover 2 drives the muscle ring 5 to rise, when the muscle ring 5 passes the buckle strip 4a, the buckle strip 4a is pushed to move outward from the outer cover 1, so as to stretch the spring 4c, when the muscle ring 5 passes the buckle strip 4a, the spring 4c drives the buckle strip 4a to reset, when the top ring 2a is inserted into the outer cover 1, the buckle strip 4a clamps the muscle ring 5, so as to fix the filter screen 2c in the outer cover 1; then the user inserts the filter cover 2 with the larger hole of the filter screen 2c in sequence, so that the top ring 2a on the lower filter cover 2 is inserted into the hollow tube 2b on the upper filter cover 2, and finally the outer cover 1 is arranged at the outlet of the juicer;

[0030] The juice and residue squeezed out by the juicer will first fall into the uppermost filter cover 2 through the outer cover 1, and then fall into the lower filter cover 2 through the filter screen 2c after being filtered once, the residue that does not pass through the filter screen 2c will stay in the filter screen 2c, and then the lower filter cover 2 will be filtered in sequence until the juice is discharged from the lowermost filter cover 2;

[0031] When the filter cover 2 needs to be cleaned, the user inserts the thumb and index finger into the two pull rings 6, and moves the two pull rings 6 away from each other, at this time the two pull rings 6 drive the buckle strip 4a and the muscle ring 5 to separate through the connecting piece 4b, at this time the filter cover 2 will fall out of the outer cover 1, and the residue in the filter cover 2 can be removed.

[0032] In addition, the user can also reduce the diameter of the filter screen 2c from bottom to top, or increase the diameter of the filter screen 2c in the filter cover 2 from top to bottom according to the minimum residue thickness that needs to be filtered by himself, so that the filter mechanism can select different final filtering accuracy according to the needs, and achieve the purpose of multi-stage filtering.

[0033] Importantly, it should be noted that the configurations and arrangements of the present application shown in a plurality of different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail herein, persons of ordinary skill in the art, in light of the disclosure, will appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters (e.g., temperatures, pressures, etc.), mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages described in the subject matter of this application.
