When the first connecting part of one filter assembly is connected with the second connecting part of another filter assembly, the liquid flow channels of the two connected filter assemblies are in communication with each other. Liquid can flow from the liquid flow channel of one filter assembly into the liquid flow channel of another filter assembly. When the filter assembly filters liquid, the liquid first flows through the liquid flow channel of one filter assembly. In this process, part of the liquid flows into the filter cavity of the filter assembly, and another part of the liquid flows into the liquid flow channel of another filter assembly connected therewith, so as to filter the liquid by the other filter assembly.

[0026] By arranging the first connecting part and the second connecting part on the support assembly, the connection between two filter assemblies can be realized by the cooperation of the first connecting part and the second connecting part of the two adjacent filter assemblies.

The structure is reliable in connection, convenient in disassembly and high in reliability.

[0031] In some technical solutions, one of the first connecting part and the second connecting part is a convex part, and the other is a concave part.

[0032] In the technical solution, another connection form of the first connecting part and the second connecting part is limited. One of the first connecting part and the second connecting part is a convex part, and the other is a concave part, and the convex part can be clamped into the concave part. In this way, the first connecting part and the second connecting part can be detachably connected through the cooperation of the convex part and the concave part. The structure can realize quick connection and disassembly between the two filter assemblies, and is high in connection efficiency.

The number of filter assemblies in the filter device is multiple, and the multiple filter assemblies are connected in sequence. Specifically, any two adjacent filter assemblies are connected through the cooperation of the first connecting part and the second connecting part, so that the multiple filter assemblies can be connected in sequence. In the case that the multiple filter assemblies are connected in sequence, the liquid flow channels in the multiple filter assemblies are sequentially communicated to form a flow channel with a certain length, and the liquid in the flow channel can gradually flow into the filter cavities of the filter assemblies in the process of flowing, thereby realizing the filtration of the liquid. Since the filter device has multiple filter assemblies, the liquid can be filtered through the filter screens in the multiple filter assemblies at the same time, so that the filtration efficiency and filtration effect of the filter device are improved.

[0069] In some embodiments, optionally, the two ends of the filter screen 140 mounted on the first filter screen mounting bracket 123 are in interference fit with the first bracket ring portion 122 and the first bracket body 121, and the two ends of the filter screen 140 mounted on the second filter screen mounting bracket 133 are in interference fit with the second bracket ring portion 132 and the second bracket body 131.

[0070] In this embodiment, the fit between the filter 140 and the support assembly 110 is defined. To ensure that the filter 140 is securely mounted on the support assembly 110, this application uses an interference fit between the filter 140 and the support assembly 110 to prevent the filter 140 from falling off. Specifically, the two ends of the filter 140 mounted on the first filter mounting bracket 123 are interference-fitted with the first support ring 122 and the first support body 121. The two ends of the filter 140 are respectively squeezed by the inner wall of the first support ring 122 and the outer wall of the first support body 121. Under the action of the squeezing force, the filter 140 is stably mounted on the first filter mounting bracket 123. The filter screen 140, mounted on the second filter mounting bracket 133, has its two ends press-fitted with the second bracket ring 132 and the second bracket body 131. The two ends of the filter screen 140 are respectively squeezed by the inner wall of the second bracket ring 132 and the outer wall of the second bracket body 131. Under this squeezing force, the filter screen 140 is stably mounted on the second filter mounting bracket 133. This ensures that the two ends of the filter screen 140 are subjected to squeezing force, thus stably mounting the filter screen 140 on the first filter mounting bracket 123 and the second filter mounting bracket 133, preventing the filter screen 140 from detaching from the bracket assembly 110.

[0071] In some embodiments, optionally, such as Figure 3 and Figure 5 As shown, the first filter mounting bracket 123 and the second filter mounting bracket 133 have grooves 113 adapted to the curved section 141.

[0072] In this embodiment, the structures of the first filter mounting bracket 123 and the second filter mounting bracket 133 are further defined. To ensure the filter 140 is more securely mounted on the first filter mounting bracket 123 and the second filter mounting bracket 133, this application provides a groove 113 in both the first filter mounting bracket 123 and the second filter mounting bracket 133. The size of the groove 113 is adapted to the curved section 141 of the filter 140, and the protruding portion of the curved section 141 can be installed within the groove 113. This allows the filter 140 to be more stably mounted on the first filter mounting bracket 123 and the second filter mounting bracket 133, improving the stability of the filter 140 installation and preventing the filter 140 from detaching from the support assembly 110. The number of grooves 113 on any first filter mounting bracket 123 and any second filter mounting bracket 133 can be one or more.

[0073] In some embodiments, optionally, such as Figure 2 As shown, the filter screen 140 is inclined, and the distance between two adjacent filter screens 140 that form the same filter chamber 142 gradually decreases along the direction away from the first support body 121 and the second support body 131.

[0074] In this embodiment, the structure of the filter screen 140 is further defined. The filter screen 140 is obliquely installed on the bracket assembly 110, so that the filter cavity 142 forms a structure with variable cross-sectional size. Specifically, in the direction away from the first bracket body 121 and the second bracket body 131, the distance between the adjacent two filter screens 140 for constituting the same filter cavity 142 gradually decreases, that is, the cross-sectional shape of the filter cavity 142 approaches a trapezoidal shape, and the distance between the two filter screens 140 is smaller at the end away from the first bracket body 121 and the second bracket body 131, and the distance between the two filter screens 140 is larger at the end close to the first bracket body 121 and the second bracket body 131. When the liquid flows in the filter cavity 142, as the cross-sectional size of the filter cavity 142 gradually decreases, the liquid pressure in the filter cavity 142 changes, and the pressure is larger at the position where the distance between the two filter screens 140 is smaller. As the liquid flows in the filter cavity 142 towards the end away from the first bracket body 121 and the second bracket body 131, the cross-sectional size of the filter cavity 142 gradually decreases, the liquid flow pressure gradually increases, and in turn, the speed of the liquid discharged from the filter screen 140 to the outside of the filter cavity 142 is accelerated, thereby improving the filtering efficiency of the filter assembly 100.

[0075] In some embodiments, as shown in Figure 2 and Figure 5 optionally, the filter assembly 100 further comprises a first connecting portion 114 provided on the bracket assembly 110, and a second connecting portion 115 provided on the bracket assembly 110, and any first connecting portion 114 of the filter assembly 100 can be detachably connected to the second connecting portion 115 of the adjacent filter assembly 100, and in the case where the first connecting portion 114 of any filter assembly 100 is connected to the second connecting portion 115 of the adjacent filter assembly 100, the liquid flow channels 111 of the two filter assemblies 100 connected to each other are communicated.

[0076] In this embodiment, the structure of the filter assembly 100 is further defined. The filter assembly 100 further comprises a first connecting portion 114 and a second connecting portion 115, which are used to connect two filter assemblies 100. Specifically, the first connecting portion 114 and the second connecting portion 115 are both arranged on the bracket assembly 110, and the first connecting portion 114 of any filter assembly 100 can be detachably connected with the second connecting portion 115 of another adjacent filter assembly 100. When the first connecting portion 114 of one filter assembly 100 is connected with the second connecting portion 115 of another filter assembly 100, the liquid flow channels 111 of the two filter assemblies 100 connected with each other are in communication with each other. Liquid can flow from the liquid flow channel 111 of one filter assembly 100 into the liquid flow channel 111 of another filter assembly 100. When the liquid is filtered by the filter assembly 100, the liquid first flows through the liquid flow channel 111 of one filter assembly 100, and in this process, part of the liquid flows into the filter cavity 142 of the filter assembly 100, and another part of the liquid flows into the liquid flow channel 111 of another filter assembly 100 connected therewith, so as to be filtered by the other filter assembly 100.

[0077] By arranging the first connecting portion 114 and the second connecting portion 115 on the bracket assembly 110, the connection between two filter assemblies 100 can be achieved by the cooperation of the first connecting portion 114 and the second connecting portion 115 of the two adjacent filter assemblies 100, so as to make the two filter assemblies 100 in communication with each other, and make the filter assemblies 100 in communication with each other collectively filter the liquid, thereby improving the filtering efficiency and filtering effect.

[0078] In some embodiments, as shown in Figure 2 and Figure 5 , the first connecting portion 114 is arranged at the top of the bracket assembly 110, and the second connecting portion 115 is arranged at the bottom of the bracket assembly 110.

[0079] In this embodiment, the arrangement positions of the first connecting portion 114 and the second connecting portion 115 are defined. The first connecting portion 114 is arranged at the top of the bracket assembly 110, and the second connecting portion 115 is arranged at the bottom of the bracket assembly 110. When the first connecting portion 114 of one filter assembly 100 is connected with the second connecting portion 115 of an adjacent filter assembly 100, the bottom of one filter assembly 100 is connected with the top of another filter assembly 100. In this way, while achieving the connection of the two filter assemblies 100, it can be ensured that the flow passage formed by the liquid flow channels 111 of the two filter assemblies 100 has a relatively long length, thereby increasing the time for the liquid to flow in the liquid flow channels 111, so that the liquid can be sufficiently filtered, and the filtering effect of the filter assembly 100 is improved.

[0080] In some embodiments, the first connecting part 114 and the second connecting part 115 are mutually matched threads.

[0081] In this embodiment, one connecting form of the first connecting part 114 and the second connecting part 115 is limited. The first connecting part 114 and the second connecting part 115 are both threads, one of the first connecting part 114 and the second connecting part 115 is an inner thread arranged on the inner wall of the liquid flow channel 111 in the second bracket body 131, and the other is an outer thread arranged on the outer wall of the first bracket body 121, and the first connecting part 114 and the second connecting part 115 are detachably connected through thread connection. This structure is reliable, easy to disassemble, and has high reliability.

[0082] In some embodiments, as shown in Figure 2 and Figure 5 , one of the first connecting part 114 and the second connecting part 115 is a convex part, and the other is a concave part.

[0083] In this embodiment, another connecting form of the first connecting part 114 and the second connecting part 115 is limited. One of the first connecting part 114 and the second connecting part 115 is a convex part, and the other is a concave part, and the convex part can be clamped into the concave part. In this way, the first connecting part 114 and the second connecting part 115 can be detachably connected through the cooperation of the convex part and the concave part. This structure can realize quick connection and disconnection between two filter assemblies 100, and has high connection efficiency.

[0084] The second aspect of the utility model further provides a filter device, and the filter assembly 100 provided by the first aspect of the utility model.

[0085] The filter device provided by the second aspect of the utility model has all the beneficial effects of the filter assembly 100 because it comprises the filter assembly 100 provided by the first aspect of the utility model.

[0086] In some embodiments, the number of filter assemblies 100 is multiple, and the multiple filter assemblies 100 are connected in sequence, and the liquid flow channels 111 of any two connected filter assemblies 100 are communicated with each other.

[0087] In this embodiment, the structure of the filter device is further limited. The number of filter assemblies 100 in the filter device is multiple, and the multiple filter assemblies 100 are connected in sequence. Specifically, any two adjacent filter assemblies 100 are connected through the cooperation of the first connecting part 114 and the second connecting part 115, so that the sequential connection of the multiple filter assemblies 100 can be achieved. In the case of sequential connection of the multiple filter assemblies 100, the liquid flow channels 111 in the multiple filter assemblies 100 are sequentially communicated to form a flow channel with a certain length. The liquid in the flow channel can gradually flow into the filter cavities 142 of the respective filter assemblies 100 during the flow process, thereby achieving filtration of the liquid. Since the filter device has multiple filter assemblies 100, the liquid can be filtered by the filter screens 140 in the multiple filter assemblies 100 at the same time, thereby improving the filtration efficiency and filtration effect of the filter device.

[0088] In some embodiments, optionally, the filter device further comprises a sealing member, and the sealing member is arranged between any two connected filter assemblies 100, and is used for sealing the gap between the two connected filter assemblies 100.

[0089] In this embodiment, the structure of the filter device is further limited. The filter device further comprises a sealing member. When two adjacent filter assemblies 100 are connected, a gap is easily formed between the two filter assemblies 100, and liquid can overflow from the gap between the two filter assemblies 100. In order to ensure the sealing performance of the filter device, the filter device further comprises multiple sealing members. The sealing members can be installed between two adjacent filter assemblies 100 to seal the gap between the two connected filter assemblies 100, thereby improving the sealing performance of the filter device.
