[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of those features. In the description of this invention, unless otherwise stated, "several" means two or more.

[0036] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "placing", "connecting", "linking", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0037] The following is for reference. Figures 1 to 4 A filter assembly according to an embodiment of the first aspect of the present invention is described.

[0038] refer to Figure 1 , Figure 2 and Figure 3 As shown, a filter assembly according to an embodiment of the present utility model includes a mounting platform 100, a filter cylinder 200, a first pressure plate 300, an elastomer 400, and a second pressure plate 500.

[0039] The mounting platform 100 has at least one first groove 110, and a through groove 111 is formed in the first groove 110. A bayonet structure 120 is provided around the first groove 110. The filter cylinder 200 includes a fixing part 210 and a filtering part 220 connected vertically. The filtering part 220 passes through the through groove 111. The fixing part 210 is movably connected in the first groove 110. A first pressure plate 300 is disposed on the fixing part 210 and is located in the first groove 110. An elastic body 400 is disposed on the first pressure plate 300. A second pressure plate 500 is disposed on the elastic body 400. The second pressure plate 500 is movably connected to the bayonet structure 120 under the action of the elastic body 400.

[0040] When the device is operating, and the filter cartridge 200 is subjected to an upward force from the water flow, the elastic buffer structure formed by the first pressure plate 300, the elastic body 400, and the second pressure plate 500 sequentially positioned at the upper end of the filter cartridge 200 absorbs and buffers the instantaneous vertical impact force generated by the filter cartridge, significantly reducing the floating amplitude of the filter cartridge and preventing it from jumping violently. Furthermore, the deformation energy received by the elastic body 400 is evenly distributed through the second pressure plate 500 to the bayonet 120 structure around the mounting platform 100, preventing the impact force from concentrating on the first groove 110 and the through groove 111 on the mounting platform 100. This effectively prevents deformation, cracking, or damage caused by collisions between the mounting platform 100 and the filter cartridge 200, significantly improving the overall strength of the installation structure and its long-term reliability. This ensures the relative stability of the filter cartridge 200 in the working state, thereby guaranteeing the continuity and stability of the filtration process and maintaining the high-efficiency filtration performance of the equipment.

[0041] It is understandable that the first groove 110 opened in the mounting platform 100 accommodates the upper end of the filter cartridge 200 and the first pressure plate 300, making the overall installation structure compact. The first pressure plate 300, the second pressure plate 500, the elastomer 400 and the three evenly distributed bayonet structures 120 cooperate to evenly disperse and buffer the impact force, optimize the force distribution, and further improve the impact resistance and structural life.

[0042] It is understandable that the elastomer 400 is set in a compressed state, which on the one hand can ensure the downward pressure on the filter cartridge 200, and on the other hand can ensure the tight connection between the second pressure plate 500 and each bayonet structure 120, thereby preventing the second pressure plate 500 and the bayonet structure 120 from being relatively displaced.

[0043] It is understandable that the fixing part 210 can be an outward-facing annular protrusion. The fixing part 210 can fit into the bottom of the first groove 110, so that the filter cylinder 200 is placed stably in the first groove 110 without horizontal movement. The filter part 220 has several small holes to achieve the filtering function.

[0044] It is understandable that the geometric centers of the first groove 110, the through groove 111, the filter cylinder 200, the first pressure plate 300, the elastomer, and the second pressure plate 500 are all on a vertical line, making the overall device more stable.

[0045] In some specific embodiments of this utility model, the bayonet structure 120 includes a first upright 121 disposed around the first groove 110. At least three first uprights 121 are provided. Each first upright 121 has a first crossbar 122 at its upper end. A second groove 1221 is provided on the lower side of the first crossbar 122 near the end of the first upright 121. A slope surface 1222 at a certain angle to the horizontal plane is provided on the lower side of the first crossbar 122 away from the first upright 121. The second pressure plate 500 can be displaced into the second groove 1221 through the slope surface 1222.

[0046] refer to Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the bayonet structure 120 is three inverted "L"-shaped structures that can be relatively movably connected with the second pressure plate 500. The setting of the second groove 1221 enables the second pressure plate 500 to be fixed on the bayonet structure 120, making the device more robust. The setting of the ramp surface 1222 makes the end of the first horizontal bar 122 away from the first vertical bar 121 thinner in the vertical direction, which makes it easier for the displacement stroke of the elastic body 400 that needs to be compressed downward when the second pressure plate 500 begins to enter the bayonet structure 120 smaller, so that it can more smoothly rotate and slide into the second groove 1221.

[0047] Understandably, when installing the device, the filter cartridge 200 is first inserted through the through groove 111, and the upper end of the filter cartridge 200 is placed in the first groove 110. Then, the first pressure plate 300 is placed on the fixing part 210, the elastic body 400 is placed at the center of the first pressure plate 300, the center of the second pressure plate 500 is aligned with the elastic body 400 and pressed down, and the second pressure plate 500 is rotated and slidably engaged in the second groove 1221 through the inclined surface 1222.

[0048] Understandably, there is a horizontal transition between the ramp surface 1222 and the second groove 1221 to prevent the ramp surface 1222 and the second groove 1221 from being directly connected, which would create a sharp corner structure at the connection point and scratch the second pressure plate 500. This also ensures the structural strength of the first crossbar 120 itself.

[0049] In some specific embodiments of this utility model, the first pressure plate 300 includes an annular first pressure-applying part 310 and a first connecting part 320 disposed on the first pressure-applying part 310, and the second pressure plate 500, the elastic body 400, the first connecting part 320, the first pressure-applying part 310 and the filter cylinder 200 are connected sequentially from top to bottom.

[0050] refer to Figure 1 and Figure 4As shown, in this embodiment, the annular first pressure-applying part 310 can evenly distribute the pressure from the elastic body 400 onto the filter cartridge 200, making the pressure on the filter cartridge 200 more uniform and stable. Simultaneously, the impact force transmitted from the filter cartridge 200 to the elastic body 400 is also more uniform. The first connecting part 320, disposed on the first pressure-applying part 310, is a plate-like structure that facilitates connection to the elastic body 400 and saves material. It can be understood that the first pressure-applying part 310 is designed to better and more smoothly transmit pressure, and its shape can also be multiple protruding structures evenly distributed around the bottom of the first mounting part 310.

[0051] In some specific embodiments of this utility model, the second pressure plate 500 includes a second pressure-applying part 510 located in the middle and a second connecting part 520 located around the second pressure-applying part 510. The second connecting part 520 is connected to the bayonet structure 120, and the second pressure-applying part 510 is connected to the elastic body 400.

[0052] refer to Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the second pressure-applying part 510 can withstand the pressure given by the elastic body 400 and distribute it to the second connecting part 520. The second connecting part 520 transmits the pressure to the three bayonet structures 120 to form a stable force balance. It can be understood that the number of the second connecting parts 520 is relative to the number of bayonet structures 120. The formation of the triangular structure helps to stably press the elastic body 400 and prevent the elastic body 400 from detaching from the side.

[0053] In some specific embodiments of this utility model, the elastic body 400 is a spring, one end of which is connected to the bottom of the second pressure plate 500, and the other end of which is connected to the top of the first pressure plate 300.

[0054] refer to Figure 1 As shown, in this embodiment, the elastomer 400 is a high-elasticity metal spring, which can play a good role in buffering and fixing. The elastomer 400 can also be made of rubber, polyurethane elastic material, gas spring, etc.

[0055] In some specific embodiments of this utility model, the mounting platform 100 is provided with six first grooves 110, as shown in the reference. Figure 1 As shown, six first grooves 110 are evenly arranged on the mounting platform 100, which can enhance the filtration capacity of the device. It can be understood that the number of first grooves 110 can also be four, eight or ten.

[0056] The following is for reference. Figures 5 to 6 A filter assembly according to a second aspect embodiment of the present invention is described.

[0057] In some specific embodiments of this utility model, the bayonet structure 120 includes a second upright 123 disposed around the first groove 110. At least two second uprights 123 are provided, and a second crossbar 124 is provided at the upper end of each second upright 123. The grooves formed by the two oppositely disposed second crossbars 124 and the second uprights 123 are opposite in direction. An arc-shaped groove 1241 is provided on the lower side of the second crossbar 124 near the end of the second upright 123.

[0058] refer to Figure 5 and Figure 6 As shown, in this embodiment, the bayonet structure 120 is two inverted "L"-shaped structures that can be relatively movably connected with the second pressure plate 500. The arc-shaped groove 1241 can fix the second pressure plate 500 on the bayonet structure 120, making the device more secure. Furthermore, the arc-shaped groove 1241 is more stable when it is in conjunction with the cylindrical second pressure plate 500, and it is easier and smoother to enter the arc-shaped groove 1241.

[0059] This utility model embodiment also discloses a filtration device, including the above-described filtration components.

[0060] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
