[0033] A juicer is a device for squeezing fruits and vegetables to extract juice, which can meet people's needs for fruit and vegetable juice intake. Juicers include squeeze-type juicers and stirring juicers, wherein the squeeze-type juicer includes a squeezing mechanism for squeezing the squeezed material, and a filter module for separating the residue of the squeezed material from the juice. The squeeze-type juicer squeezes juice by squeezing fruits and vegetables, and the juice of fruits and vegetables contains less residue than that of the stirring juicer. When squeezing the squeezed material, the squeeze mechanism of the squeezer will compress the squeezed material placed on the filter module to a fixed thickness, but the size of the squeezed material varies. The filter module may be subjected to more pressure from the squeezing mechanism due to the larger size of the squeezed material, thereby causing the filter module to be damaged by plastic deformation. To this end, the utility model proposes a filter assembly, which is intended to reduce the pressure exerted by the juicer on the filter module, thereby reducing the possibility of deformation and damage of the filter module due to excessive pressure.

[0034] Reference Figures 1 to 6In one embodiment of the utility model, the filter assembly is applied to a juicer, the juicer includes a base 600, the filter assembly includes a filter module and an elastic buffer 200, the filter module includes a filter 100 for placing a squeezed object 900, the filter 100 is provided with a plurality of filter holes 110, the filter holes 110 are used for allowing juice of the squeezed object 900 to flow through, the filter module and the base 600 have a buffer gap 300 in the first direction, so that the filter module can move along the first direction after being compressed, the elastic buffer 200 connects the filter module and the base 600, and in the process of the buffer gap 300 becoming smaller, the elastic deformation of the elastic buffer 200 increases.

[0035] The squeezed object 900 in the present solution can be oranges, tangerines, watermelons, lychees, cucumbers, etc., and the present application does not limit this. In order to facilitate the understanding of the present solution, the squeezed object 900 in this article is introduced by taking oranges as an example. When the juicer is squeezing the oranges, the juicer squeezes the oranges to form pomace of a set thickness. The squeezed orange juice flows into the filter hole 110 to be separated from the orange pomace. Since the sizes of oranges vary, and the juicer cannot identify oranges of different sizes and adjust the thickness of the squeezed pomace, the juicer squeezes oranges of different sizes into pomace of almost the same thickness. When the size of the orange is large, the juicer needs to apply greater pressure to the orange to cooperate with the filter 100 module to squeeze the orange, so that the larger orange can be squeezed into pomace of the same thickness as the smaller orange. In this process, the filter module needs to withstand a greater external force than squeezing an orange of a smaller size, and the filter module may be plastically deformed and damaged.

[0036] Therefore, a buffer gap 300 is set between the filter module and the base 600, and an elastic buffer member 200 is set to connect the base 600 and the filter module. When the filter module is displaced in the first direction due to force, the buffer gap 300 gradually decreases. At this time, the elastic buffer member 200 absorbs the external force transmitted from the filter module and shrinks to share the external force applied to the filter module, thereby reducing the possibility of damage to the filter module due to plastic deformation caused by a large external force, thereby improving the operating stability of the juicer and being suitable for squeezing oranges of different sizes.

[0037] Optionally, in one embodiment, the filter module further includes a guide post 510 connected to the filter 100, the base 600 is provided with a guide hole 620 for the guide post 510 to pass through, the elastic buffer 200 is sleeved on the outer circumference of the guide post 510, and one end of the elastic buffer 200 is provided at the edge of the guide hole 620. In this way, the guide post 510 is provided so that the filter module can be displaced along the guide post 510 in the first direction, the displacement of the filter module along its circumference is limited, and the possibility of the filter module being offset on the base 600 is reduced. The elastic buffer 200 is sleeved on the outer circumferential surface of the guide column 510. When the guide column 510 moves downward along the guide hole 620, the filter module compresses the elastic buffer 200, so that the elastic buffer 200 absorbs the external force transmitted from the filter module, thereby reducing the external force borne by the filter module. The elastic buffer 200 is sleeved on the outer circumferential surface of the guide column 510, and one end of the elastic buffer 200 is against the edge of the guide hole 620, so that the elastic buffer 200 is not easily offset and separated from the guide column 510 and the guide hole 620.

[0038] Optionally, in one embodiment, the base 600 is further provided with a mounting hole 630 connected to the guide hole 620, the guide hole 620 is provided at the bottom wall of the mounting hole 630, and the elastic buffer 200 is at least partially provided in the mounting hole 630. In this way, the mounting hole 630 is provided, and the guide column 510 is installed in the mounting hole 630 to achieve the installation of the filter module on the base 600. The elastic buffer 200 is partially provided in the mounting hole 630, which can effectively limit the displacement of the elastic buffer 200 in the circumferential direction of the mounting hole 630, and reduce the possibility that the elastic buffer 200 deviates in the circumferential direction of the mounting hole 630 and separates from the guide column 510.

[0039] Optionally, in another embodiment, there may be many ways to connect the filter module and the base 600, and the guide column 510 may be omitted. One end of the elastic buffer 200 may be fixed to the lower surface of the filter module, and the other end may be fixed to the edge of the guide hole 620. As long as the filter module can be installed on the base 600 and the elastic buffer 200 can achieve the buffering effect on the filter module, it will be sufficient.

[0040] Optionally, in one embodiment, the base 600 is provided with a positioning groove 610 corresponding to the filter module, at least part of the filter module can be adapted to be embedded in the positioning groove 610 along the first direction, and the mounting hole 630 is provided on the bottom wall of the positioning groove 610. In this way, the positioning groove 610 is provided on the base 600, so that the filter module can be embedded in the positioning groove 610 in the first direction, so as to limit the displacement of the filter module along its circumferential direction, reduce the possibility that the filter module is displaced in its circumferential direction and deviates from the base 600, thereby causing the guide column 510 to break, improve the stability of the filter module on the base 600, and facilitate the installation of the filter module on the base 600.

[0041] Optionally, in another embodiment, there are many ways to limit the circumferential movement of the filter module. Multiple limit rods can be set on opposite sides of the base 600, and the limit rods are used to abut against the sides of the filter module to limit the circumferential displacement of the filter module.

[0042] Optionally, in one embodiment, the filter module further includes two mounting brackets 500 disposed on opposite sides of the filter 100, the guide column 510 is convexly disposed on the lower surface of the mounting bracket 500, the two mounting brackets 500 are distributed along the second direction, and are positioned to abut against the groove sidewall of the positioning groove 610 in the second direction, and the second direction is arranged to intersect with the first direction. In this way, the filter module is connected to the base 600 through the mounting bracket 500, and the mounting bracket 500 abuts against the groove sidewall of the positioning groove 610 in the second direction to limit the displacement of the filter module in the second direction, and reduce the possibility that the filter module is greatly displaced in the second direction and deviates from the base 600, thereby causing the guide column 510 to receive shear force in the second direction and break.

[0043] Optionally, in another embodiment, there can be many ways to connect the filter module and the base 600, and the mounting bracket 500 can be omitted. The guide column 510 is fixed to the lower surface of the filter module, and the side of the filter module is abutted against the side wall of the positioning groove 610 in the second direction.

[0044] Optionally, in one embodiment, the filter module further includes a frame 400, the end of the frame 400 is arranged on the mounting bracket 500, and the middle part of the frame 400 at least partially abuts against the lower surface of the filter 100 to support the filter 100. In this way, at least a part of the middle part of the frame 400 abuts against the lower surface of the filter 100 to support the filter 100, limit the deformation of the filter 100 toward the frame 400, reduce the deformation amount of the filter 100 toward the frame 400 when the filter 100 is subjected to external force, reduce the possibility of the filter 100 being too deformed and unable to recover to the original state or structural damage, and effectively improve the structural strength and pressure-bearing capacity of the filter module.

[0045] Optionally, in another embodiment, the structure of the skeleton 400 may be omitted to reduce the weight of the filter module itself.

[0046] Optionally, in one embodiment, the lower surface of the mounting bracket 500 is provided with a limiting rib 520, and when the filter module moves to the lower limit position along the first direction, the limiting rib 520 abuts against the bottom surface of the positioning groove 610. In this way, it can be understood that the distance between the position of the limiting rib 520 moving from the initial state to the position just abutting against the bottom surface of the positioning groove 610 is the set maximum elastic deformation value that the elastic buffer 200 can provide. The limiting rib 520 is provided on the lower surface of the mounting bracket 500, and when the filter module moves along the first direction so that the buffer gap 300 can no longer be further reduced, the limiting rib 520 abuts against the bottom surface of the positioning groove 610, thereby limiting the filter module from continuing to move along the first direction, which can effectively reduce the possibility of the elastic buffer 200 being damaged by plastic deformation due to absorbing excessive external force.

[0047] Optionally, in another embodiment, a buffer pad may be provided at the bottom of the limiting rib 520 to reduce the impact force between the limiting rib 520 and the bottom surface of the positioning groove 610 .

[0048] Optionally, in one embodiment, the skeleton 400 includes intersecting main keels 410 and secondary keels 420, the main keels 410 extend along the second direction and are arranged in plurality at intervals, the ends of the plurality of main keels 410 are connected to the mounting bracket 500, and the secondary keels 420 are arranged in plurality, and the plurality of secondary keels 420 are arranged in plurality, and the plurality of secondary keels 420 are arranged in intervals along the second direction. In this way, by setting the main keel 410 and the secondary keel 420 abutting against the lower surface of the filter screen 100, the deformation of the filter screen 100 toward the skeleton 400 is restricted, and at the same time, the secondary keel 420 extends in the distribution direction of the main keel 410 to connect the plurality of main keels 410, so that the structure formed by the plurality of main keels 410 is more compact, thereby improving the overall structural strength of the skeleton 400, and the secondary keel 420 can also restrict the displacement of the main keel 410 in its distribution direction, so that the main keel 410 is more stable.

[0049] Optionally, in another embodiment, the skeleton 400 may have many structural forms, and the secondary keel 420 may be omitted, and only a plurality of main keels 410 abutting against the lower surface of the filter 100 may be provided, as long as the skeleton 400 can support the filter 100.

[0050] Optionally, in one embodiment, the filter screen 100 is made of metal. In this way, the filter screen 100 is made of metal material, so that the filter screen 100 has greater compression and bending resistance, and the filter screen 100 is not easily subjected to force and irreversible deformation occurs.

[0051] Furthermore, in one embodiment, the filter 100 can be made of stainless steel. On the one hand, the filter 100 can have a higher rigidity and is not easily subjected to force and deformed significantly. On the other hand, the filter 100 made of stainless steel has strong corrosion resistance and can effectively prevent the erosion of fruit acid in orange juice and extend the service life of the filter 100.

[0052] Optionally, in one embodiment, the upper surface of the filter 100 is configured as a concave cone. It is worth mentioning that in the present application, a complete orange with peel is used for squeezing, so that the upper surface of the filter 100 is configured as a concave cone, so that the complete orange placed on the upper surface of the filter 100 can roll to the center of the filter 100 spontaneously under the action of gravity, making it easier for the juicer to squeeze the orange to extract juice.

[0053] The utility model also proposes a juicer, which includes a frame 820, a base 600, a rolling disc 700, a first drive device 830, a second drive device 840, a juice storage box 810, and a filter assembly. The specific structure of the filter assembly refers to the above embodiment. Since the juicer adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the rolling disc 700 and the filter 100 for placing oranges are arranged on the frame 820, the rolling disc 700 is arranged above the filter 100 at intervals, and forms a squeezing space with the filter 100, the filter 100 is provided with a filter hole 110, and the juice storage box 810 is arranged below the filter 100 to receive the orange juice flowing out of the filter hole 110. The first drive device 830 and the second drive device 840 are both arranged on the frame 820. When squeezing juice, the first drive device 830 drives the rolling disc 700 to squeeze the orange juice. In the eccentric rolling process, the second driving device 840 drives the base 600 to move toward the rolling disc 700. At this time, the filter 100 follows the base 600 to move toward the rolling disc 700 to reduce the squeezing space so that the oranges can be squeezed to extract juice between the filter 100 and the rolling disc 700. After the juicing is completed, the first driving device 830 stops driving the eccentric movement of the rolling disc 700, and the second driving device 840 drives the base 600 to drive the filter 100 to move in the direction away from the rolling disc 700, thus completing one juicing operation.
