[0030] A juicer is a device used to squeeze juice out of fruits and vegetables. A juicer can meet people's demand for consuming juice from fruits and vegetables. A general juicer includes a squeezing mechanism for squeezing fruits and vegetables, and a filter for separating the residue of the squeezed fruits and vegetables from the juice. When squeezing fruits and vegetables, the juicer relies on the squeezing mechanism to apply pressure to the squeezed material to cooperate with the filter to squeeze the squeezed material to extract the juice from the squeezed material. Therefore, during this squeezing process, the filter needs to withstand the force transmitted from the squeezing mechanism. Due to the limited structural strength of the filter itself, it may undergo plastic deformation or even structural damage, thereby affecting the subsequent squeezing of the squeezed material. To this end, the utility model proposes a filter assembly, which aims to improve the pressure-bearing capacity of the filter and reduce the plastic deformation of the filter due to excessive pressure.

[0031] Reference Figures 1 to 5In one embodiment of the present invention, the filter assembly is applied to a juicer, which includes a base 800. The filter assembly includes a filter 100 and a frame 200. The filter 100 is used to place the squeezed material 900 and is provided with a plurality of filter holes 110. The filter holes 110 are used to allow the juice of the squeezed material 900 to flow through. The frame 200 is arranged below the filter 100. The frame 200 includes a plurality of main keels 210 arranged at intervals. The ends of the main keels 210 are installed on the base 800. The upper surfaces of the main keels 210 at least partially abut against the lower surface of the filter 100 to support the filter 100. The squeezed object 900 in this solution can be oranges, tangerines, watermelons, lychees, cucumbers, etc., and this application does not limit this. To facilitate understanding of this solution, the squeezed object 900 in this article is introduced using oranges as an example. The filter 100 is used to place the oranges. When the juicer is squeezing the oranges, the juicer applies pressure to the oranges to cooperate with the filter 100 to squeeze the oranges, flattening the oranges to obtain orange juice. The squeezed orange juice flows into the filter holes 110 of the filter 100 and is separated from the orange pomace. At this time, the filter 100 will be subjected to the force transmitted from the juicer and deformed in the direction away from the oranges. If the deformation of the filter 100 is too large, the filter 100 may undergo plastic deformation, and may even cause damage to the structure of the filter 100, thereby affecting the subsequent squeezing of the oranges. In view of this, a skeleton 200 installed on the base 800 is provided below the filter 100, and the upper surface of the main keel 210 of the skeleton 200 is at least partially in contact with the lower surface of the filter 100 to support the filter 100 and limit the deformation of the filter 100 toward the skeleton 200, so as to reduce the deformation amount of the filter 100 toward the skeleton 200 when the filter 100 is subjected to external force, thereby reducing the possibility of plastic deformation or structural damage of the filter 100, and effectively improving the structural strength and pressure-bearing ability of the filter 100.

[0032] Optionally, in one embodiment, the filter assembly further includes two mounting brackets 230, wherein the first ends of the plurality of main keels 210 are connected to one of the mounting brackets 230, and the second ends of the plurality of main keels 210 are connected to the other mounting bracket 230, and the mounting bracket 230 is connected to the base 800. In this way, the first ends of the plurality of main keels 210 are connected to one of the mounting brackets 230, and the second ends of the plurality of main keels 210 are connected to the other mounting bracket 230. In this way, the plurality of main keels 210 are mounted on the two mounting brackets 230, making the structure of the plurality of main keels 210 and the mounting brackets 230 compact, enhancing the structural strength of the plurality of skeletons 200, and enabling the skeleton 200 to withstand greater weight and external forces.

[0033] Optionally, in another embodiment, the main keel 210 can be installed in many ways, and the mounting bracket 230 can be omitted. The main keel 210 can be directly installed on the base 800, which can still play a supporting role for the filter 100.

[0034] Optionally, in one embodiment, the mounting bracket 230 is provided with a receiving slot 231 for receiving and inserting the end of the main keel 210. The filter screen 100 assembly further includes a mounting rod 240 disposed in the receiving slot 231. The ends of the mounting rod 240 are respectively connected to two opposite side walls of the receiving slot 231 and are passed through and connected to the ends of the plurality of main keels 210. In this manner, the ends of the plurality of main keels 210 are inserted into the receiving slot 231, and the mounting rod 240 is provided to pass through and connect the ends of the plurality of main keels 210. Thus, the ends of the plurality of main keels 210 on the same side are connected to the same mounting rod 240. This enhances the connectivity between the plurality of main keels 210, makes the overall structure of the frame 200 more compact, improves the overall structural strength of the plurality of frames 200, enables the frame 200 to withstand greater weight and external forces, and thereby facilitates the installation of the main keels 210 on the mounting bracket 230.

[0035] Optionally, in another embodiment, there are many ways to install the main keel 210 on the mounting bracket 230, and the mounting rod 240 can be omitted, and the end of the main keel 210 can be directly adhered to the groove wall of the receiving groove 231 to complete the installation of the main keel 210 on the mounting bracket 230.

[0036] Alternatively, in one embodiment, the main keel 210 is provided in a plate-like structure and includes a connected middle plate section 211 and end plate sections 212. The ends of the main keel 210 are formed at the end plate sections 212. The upper surface of the end plate sections 212 is lower than the upper surface of the middle plate section 211. An upper step 213 is formed at the intersection of the two plates. The upper step 213 abuts against the edge of the receiving slot 231. Thus, the abutment between the upper step 213 of the main keel 210 and the edge of the receiving slot 231 limits the displacement of the main keel 210 along its length, reducing the amount of displacement of the main keel 210 along its length due to force when the juicer is used to squeeze oranges. This improves the stability of the main keel 210, making it less likely to cause displacement along its length and structural deformation, thereby enhancing the structural strength of the skeleton 200.

[0037] Optionally, in another embodiment, there are many ways to limit the displacement of the main keel 210 in its length direction. The end of the main keel 210 can also be abutted against the groove wall of the receiving groove 231 to limit the displacement of the main keel 210 in its length direction.

[0038] Optionally, in one embodiment, the lower surface of the end plate segment 212 is higher than the lower surface of the middle plate segment 211, and a lower step 214 is formed at the intersection thereof. A gap is provided between the lower step 214 and the edge of the slot of the receiving slot 231. Thus, by setting the lower surface of the end plate segment 212 of the main keel 210 higher than the lower surface of the middle plate segment 211 and providing a gap between the step and the edge of the slot of the receiving slot 231, over-positioning of the main keel 210 can be avoided, allowing the main keel 210 to have a larger dimension in its height direction. This can effectively improve the main keel 210's ability to resist compression and bending in its height direction, enhance the overall structural strength of the skeleton 200, and facilitate installation of the main keel 210 on the mounting bracket 230.

[0039] Optionally, in another embodiment, the lower step portion 214 of the main keel 210 can also be set to abut against the edge of the slot 231, as long as the installation of the pig main keel 210 and the supporting function of the main keel 210 on the filter 100 can be achieved.

[0040] Optionally, in one embodiment, the skeleton 200 further includes a plurality of secondary keels 220, which extend along the distribution direction of the plurality of main keels 210 and connect the plurality of main keels 210. In this way, a plurality of secondary keels 220 are installed on the upper surface of the main keel 210. The main keel 210 and the secondary keel 220 can withstand greater weight and external force, thereby enhancing the bearing capacity and bending resistance of the skeleton 200, making it less likely that the main keel 210 will be greatly deformed and damaged when subjected to a large external force or weight. At the same time, the secondary keels 220 extend in the distribution direction of the main keels 210 to connect the plurality of main keels 210, making the structure formed by the plurality of main keels 210 more compact, thereby improving the overall structural strength of the skeleton 200. The secondary keels 220 can also limit the displacement of the main keels 210 in their distribution direction, making the main keels 210 more stable.

[0041] Optionally, in another embodiment, the secondary keel 220 can be set in many ways, and only one secondary keel 220 can be set to be connected to the upper surface of the main keel 210 and extend along the distribution direction of the main keel 210, as long as it can limit the displacement of the main keel 210 in its distribution direction and improve the structural strength of the skeleton 200.

[0042] Optionally, in one embodiment, the upper surface of the secondary keel 220 is flush with the upper surface of the main keel 210, and the upper surface of the secondary keel 220 at least partially abuts the lower surface of the filter screen 100 to provide support for the filter screen 100. In this way, the upper surface of the secondary keel 220 is flush with the upper surface of the main keel 210, so that the upper surface of the secondary keel 220 does not first contact the filter screen 100, thereby separating the upper surface of the main keel 210 from the filter screen 100, resulting in the upper surface of the main keel 210 not contacting the filter screen 100 and reducing the support effect of the main keel 210 on the filter screen 100; at the same time, the upper surface of the secondary keel 220 abuts the lower surface of the filter screen 100, cooperating with the main keel 210, further enhancing the support effect of the frame 200 on the filter screen 100.

[0043] Optionally, in another embodiment, the upper surface of the secondary keel 220 may be arranged lower than the upper surface of the main keel 210 , as long as the upper surface of the secondary keel 220 does not interfere with the contact between the upper surface of the main keel 210 and the lower surface of the filter 100 .

[0044] Optionally, in one embodiment, the middle portion of the filter 100 is convexly arranged toward the skeleton 200, and the upper surface of the main keel 210 and the upper surface of the secondary keel 220 are correspondingly concave arc surfaces, and are adapted to fit on the lower surface of the filter 100. It is worth mentioning that in the present application, a complete orange with peel is used for squeezing. In this way, the middle portion of the filter 100 is convexly arranged toward the skeleton 200, so that the complete orange placed on the upper surface of the filter 100 can spontaneously roll to the middle portion of the filter 100 under the action of gravity, thereby achieving the positioning of the orange and facilitating the juicer to squeeze the orange to extract juice. The upper surface of the main keel 210 and the upper surface of the secondary keel 220 are arranged to correspond to the concave arc surface of the filter 100, so that the upper surfaces of the main keel 210 and the secondary keel 220 can fit on the filter. The lower surface of the filter screen 100 is supported by the main keel 210 and the auxiliary keel 220, and the main keel 210 and the auxiliary keel 220 are arranged in contact with the lower surface of the filter screen 100 to limit the displacement of the filter screen 100 toward the skeleton 200, thereby reducing the possibility of the filter screen 100 being greatly deformed due to a large external force. When the filter screen 100 is greatly deformed in the direction toward the skeleton 200, the filter screen 100 may not be able to return to its original state or even be damaged, thereby affecting the subsequent squeezing of the oranges.

[0045] Optionally, in another embodiment, the structure of the filter 100 can be in many forms, and the middle of the filter 100 can be set flush with the periphery of the filter 100, and the main keel 210 and the secondary keel 220 can be adapted to fit the lower surface of the filter 100, as long as the filter 100 can support the oranges and the skeleton 200 can support the filter 100.

[0046] Optionally, in one embodiment, the main keel 210 and the secondary keel 220 are arranged in a plate-like structure, with a first slot 215 provided on the upper surface of the main keel 210 corresponding to the secondary keel 220, and a second slot 221 provided on the lower surface of the secondary keel 220 corresponding to the main keel 210, wherein the first slot 215 and the second slot 221 are arranged to be inserted into each other. In this manner, the first slot 215 and the second slot 221 are arranged, and the second slot 221 of the secondary keel 220 is inserted into the first slot 215 of the main keel 210 to achieve installation of the secondary keel 220 on the main keel 210. Furthermore, the first slot 215 is provided on the upper surface of the main keel 210, and the second slot 221 is provided on the lower surface of the secondary keel 220, so that after the secondary keel 220 is installed on the main keel 210, the upper surface of the secondary keel 220 is flush with the upper surface of the main keel 210.

[0047] Optionally, in another embodiment, there can be many ways to connect the main keel 210 and the secondary keel 220. The secondary keel 220 can also be fixed to the upper surface of the main keel 210 by bolts, and the secondary keel 220 extends along the distribution direction of the main keel 210. As long as the secondary keel 220 can be installed on the main keel 210, it will be sufficient.

[0048] The utility model also proposes a juicer, referring to Figures 3 to 5 The juicer includes a frame 500, a base 800, a rolling disc 300, a first drive device 600, a second drive device 700, a juice storage box 400, and a filter assembly. The specific structure of the filter assembly is as described above. Since the juicer adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here. Among them, the rolling disc 300 and the filter 100 for placing oranges are arranged on the frame 500. The rolling disc 300 is arranged above the filter 100 at an interval and forms a squeezing space with the filter 100. The rolling disc 300 has a squeezing area 310 for squeezing oranges. The filter 100 has filter holes 110. The juice storage box 400 is arranged below the filter 100 to receive the orange juice flowing out of the filter holes 110. The first drive device 600 and the second drive device 700 are both arranged on the frame 500. When squeezing juice, the first drive device 600 The rolling disc 300 is driven to perform oscillatory rolling, and the second driving device 700 drives the base 800 to move toward the rolling disc 300. At this time, the filter 100 follows the base 800 to move toward the rolling disc 300 to reduce the squeezing space, so that the juice is squeezed out of the oranges between the filter 100 and the rolling disc 300. After the juicing is completed, the first driving device 600 stops driving the oscillatory motion of the rolling disc 300, and the second driving device 700 drives the base 800 to move the filter 100 away from the rolling disc 300, thus completing one juicing operation.

[0049] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
