Description

Technical Field

[0001] This utility model relates to the field of juicer technology, and in particular to a filter component. Background Technology

[0002] A juicer is a machine that uses mechanical methods to press fruits or vegetables into juice. It mainly uses a screw structure to squeeze the fruits and vegetables to be juiced, thereby separating the juice.

[0003] Existing juicers include a base, a juicing cup mounted on the base, a screw body rotatably mounted inside the juicing cup, and a filter cover surrounding the screw body. The screw body is used to press small pieces of food to extract juice, and the peripheral wall of the filter cover has mesh holes for the juice to flow out.

[0004] During juicing, as the screw rotates, the ingredients are squeezed out of juice and discharged through the mesh. However, the pulp squeezed by the screw also moves into the mesh. Because the mesh is numerous and small, the debris accumulates continuously. After using this traditional filter, it is difficult to clean the pulp stuck in the mesh because the mesh is small.

When cleaning the filter assembly, the user can disassemble the first and second filter components to rinse the first and second grid bars separately, effectively solving the problem of traditional fine-mesh filter covers being difficult to clean thoroughly due to embedded and clogged fruit pulp. Simultaneously, the interference fit between the first and second mating parts ensures the structural stability after assembly, preventing the first and second filter components from loosening or separating during the juicing process.

[0012] According to some embodiments of the present invention, one of the first mating part and the second mating part is a groove, and the other is a fixing protrusion, wherein the fixing protrusion abuts against the side wall of the groove.

[0044] In related technologies, a juicer includes a base, a juicing cup mounted on the base, a screw mounted rotatably inside the juicing cup, and a filter cover surrounding the screw. The screw is used to press small pieces of food to extract juice, and the filter cover has mesh holes on its peripheral wall for the juice to flow out. During juicing, as the screw rotates, the food is squeezed out of juice and discharged through the mesh holes. However, at the same time, the pulp squeezed by the screw also moves into the mesh holes. Because the mesh holes are numerous and small, the pulp accumulates continuously. After using this traditional filter cover, it is difficult to clean the pulp stuck in the mesh holes because the mesh holes are relatively small.

[0045] Reference Figures 1 to 5 According to a first aspect embodiment of the present invention, a filter assembly includes a first filter element 100 and a second filter element 200. The first filter element 100 includes a first connecting ring 110 and a plurality of first grid bars 120. One end of each first grid bar 120 is connected to the first connecting ring 110, and the plurality of first grid bars 120 are spaced apart around the axis of the first connecting ring 110. The first connecting ring 110 is provided with a plurality of first mating portions 111, which are located between adjacent first grid bars 120. The second filter element 200 is detachably connected to the first filter element 100. The second filter element 200 includes a second connecting ring 210 and a plurality of second grid bars 220. One end of each second grid bar 220 is connected to the second connecting ring 210, and the plurality of second grid bars 220 surround the first connecting ring 100. The two connecting rings 210 are spaced apart along their axes. The number of first grid bars 120 and second grid bars 220 is equal. Each second grid bar 220 is inserted between two adjacent first grid bars 120. The second grid bars 220 and their corresponding first grid bars 120 are spaced apart to form a filter gap 300, which is used for fruit pulp. Each second grid bar 220 has a second mating part 221 at its end away from the second connecting ring 210. The first mating part 111 is press-fitted with its corresponding first mating part 111. When cleaning the filter assembly, the user can disassemble the first filter element 100 and the second filter element 200 to rinse the first grid bars 120 and the second grid bar 220 respectively, effectively solving the problem that traditional fine mesh filter covers are difficult to clean thoroughly due to fruit pulp embedding and clogging. At the same time, the press-fit between the first mating part 111 and the second mating part 221 ensures the structural stability after assembly, preventing the filter element from loosening or separating during juicing.

[0046] For example, during the juicer's operation, the pulp is isolated by the first grid bar 120 and the second grid bar 220, while the juice flows out through the filter gap 300. When cleaning the filter assembly, the user can disassemble the first filter element 100 and the second filter element 200 to rinse the first grid bar 120 and the second grid bar 220 respectively, effectively solving the problem of traditional fine mesh filter covers being difficult to clean thoroughly due to pulp embedding and clogging. At the same time, the interference fit between the first mating part 111 and the second mating part 221 ensures the structural stability after assembly, preventing the first filter element 100 and the second filter element 200 from loosening or separating during the juicing process.

[0047] In some embodiments of this utility model, the first mating part 111 is a groove, and the second mating part 221 is a fixing protrusion. The fixing protrusion abuts against the side wall of the groove, which can prevent the first filter element 100 and the second filter element 200 from loosening or separating during the juicing process, thereby improving the filtration effect of the filter assembly and enhancing the user experience of the juicer.

[0048] It should be noted that by setting the first mating part 111 and the second mating part 221, there is no need to use additional fasteners to fix the first filter element 100 and the second filter element 200. The operation is simple, convenient and quick, and can reduce the production cost of the filter components.

[0049] In another embodiment, the first mating part 111 is a fixed protrusion and the second mating part 221 is a groove. The fixed protrusion abuts against the side wall of the groove, which can also prevent the first filter element 100 and the second filter element 200 from loosening or separating during the juicing process.

[0050] It is understandable that during the juicing process of a juicer, the filter components are prone to deformation when subjected to the radial pressure generated by the screw extruding the food.

[0051] Based on this, in some embodiments of the present invention, the first filter element 100 further includes a third connecting ring 130, which is connected to the end of each first grid bar 120 away from the first connecting ring 110. This can enhance the overall structural rigidity and strength of the first filter element 100, making it less prone to deformation when subjected to the radial pressure generated by the screw body 500 squeezing the food, ensuring the uniformity and stability of the filter gap 300, and extending the service life of the filter assembly.

[0052] In some embodiments of this utility model, the first filter element 100 further includes a reinforcing ring 140, which is connected to each of the first grid bars 120. Along the axial direction of the first connecting ring 110, the reinforcing ring 140 is located between the first connecting ring 110 and the third connecting ring 130, further improving the structural strength and deformation resistance of the first filter element 100. Especially in the middle region of the first grid bar 120, it can effectively prevent the first grid bar 120 from bending or twisting during high-pressure juicing, ensuring that the filtration gap 300 maintains its designed shape and maintains stable filtration performance.

[0053] In some embodiments of this utility model, the first connecting ring 110, the third connecting ring 130, the reinforcing ring 140, and the first grid bar 120 are an integral structure, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the first filter element 100.

[0054] For example, the first connecting ring 110, the third connecting ring 130, the reinforcing ring 140 and the first grid bar 120 can be integrally formed by injection molding, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the first filter element 100.

[0055] In another embodiment, the first connecting ring 110, the third connecting ring 130, the reinforcing ring 140 and the first grid bar 120 can be connected by welding, wherein the welding method includes, but is not limited to, resistance welding, laser welding or ultrasonic welding.

[0056] In some embodiments of this utility model, a first reinforcing protrusion 150 is provided on the side of the first grid bar 120 away from the axis of the first connecting ring 110. The first reinforcing protrusion 150 is used to insert into the inner peripheral wall of the juicing cup 400 of the juicer, so that the filter assembly can be accurately positioned and securely installed in the juicing cup 400, effectively preventing the filter assembly from rotating or axially moving in the cup during the juicing process, and ensuring the stability of the juicing process and the consistency of the filtration effect.

[0057] For example, among the multiple first grid bars 120, some of the first grid bars 120 are provided with first reinforcing protrusions 150. The inner peripheral wall of the juicer cup 400 is provided with slots, the number of slots being equal to the number of first reinforcing protrusions 150. The first reinforcing protrusions 150 are inserted into the corresponding slots, and the first reinforcing protrusions 150 abut against the side wall of the corresponding slots, so that the filter assembly can be accurately positioned and securely installed in the juicer cup 400, effectively preventing the filter assembly from rotating or axially moving in the cup during the juicing process, ensuring the stability of the juicing process and the consistency of the filtration effect.

[0058] It should be noted that each of the first grid bars 120 may also have a first reinforcing protrusion 150, which is not limited here.

[0059] In some embodiments of this utility model, a second reinforcing protrusion 230 is provided between each second grid bar 220 and the second connecting ring 210, which can improve the structural strength of the root of the second grid bar 220. The second reinforcing protrusion 230 can effectively resist stress concentration, prevent the root of the second grid bar 220 from breaking or deforming, and improve the service life of the second filter element 200.

[0060] In some embodiments of this utility model, a portion of the second reinforcing protrusion 230 is located on the inner peripheral wall of the second connecting ring 210, so that the second reinforcing protrusion 230 can assist the screw body 500 in crushing food, thereby improving the juicing efficiency of the juicer.

[0061] For example, when the juicer is working, the screw body 500 drives the food to rotate, and the food collides with the second reinforcing protrusion 230, so that the second reinforcing protrusion 230 can assist the screw body 500 in crushing the food, thereby improving the juicer's juicing efficiency.

[0062] In some embodiments of this utility model, the second grid bar 220 and the second connecting ring 210 are an integral structure, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the first filter element 100.

[0063] For example, the second grid bar 220 and the second connecting ring 210 can be integrally formed by injection molding, which can reduce the number of molds and reduce the production cost of the molds, thereby reducing the production cost of the first filter element 100.

[0064] In another embodiment, the second grid bar 220 and the second connecting ring 210 can be connected by welding, wherein the welding method includes, but is not limited to, resistance welding, laser welding or ultrasonic welding.

[0065] Reference Figure 6 , Figure 7According to a second aspect embodiment of the present invention, a juicer includes a base, a juicing cup 400, a screw body 500, and a filter assembly according to a first aspect embodiment of the present invention. The base has a power output end, the juicing cup 400 is disposed on the base, the screw body 500 is rotatably disposed within the juicing cup 400 and connected to the power output end, and the filter assembly is disposed within the juicing cup 400 and arranged around the screw body 500. When cleaning the filter assembly, the user can disassemble the first filter element 100 and the second filter element 200 to rinse the first grid bar 120 and the second grid bar 220 respectively, effectively solving the problem that traditional fine mesh filter covers are difficult to clean thoroughly due to residue embedding and clogging. At the same time, the interference fit between the first mating part 111 and the second mating part 221 ensures the structural stability after assembly and prevents the filter element from loosening or separating during the juicing process.

[0066] For example, during the juicer's operation, the pulp is isolated by the first grid bar 120 and the second grid bar 220, while the juice flows out through the filter gap 300. When cleaning the filter assembly, the user can disassemble the first filter element 100 and the second filter element 200 to rinse the first grid bar 120 and the second grid bar 220 respectively, effectively solving the problem of traditional fine mesh filter covers being difficult to clean thoroughly due to pulp embedding and clogging. At the same time, the interference fit between the first mating part 111 and the second mating part 221 ensures the structural stability after assembly, preventing the first filter element 100 and the second filter element 200 from loosening or separating during the juicing process.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
