A common installation method for filter cartridges is a snap-fit ​​structure, where the cartridge has snaps at the top and holes at the bottom of the mounting plate. During installation, the cartridge is forced into the holes by the deformation of the snaps, and it is also pulled out by the deformation of the snaps. This method is laborious and the snap-fit ​​structure is prone to damage. Summary of the Invention

[0008] Furthermore, with the through hole on the filter element fixing plate as the axial direction, the anti-detachment groove is a long groove, the length of the long groove extends radially along the through hole, and the surface of the anti-detachment groove is smooth.

[0009] Furthermore, the buckles are evenly distributed, and the number of buckles and slots is the same and evenly distributed.

[0010] Furthermore, the cover plate and the outer shell are welded together by a spin welding process, with a buckle set on the end face of the cover plate, and multiple evenly distributed protrusions on the end face of the outer shell.

[0036] like Figure 1-10 As shown, this embodiment discloses a rotary snap-fit ​​filter element, including a filter element body 1 and a filter element fixing plate 2. The filter element body 1 contains filter media. Both ends of the filter element body 1 are respectively provided with two-point straight rod interfaces that communicate with the filter element body 1. At least two buckles 112 are provided in the circumferential direction of one end face of the filter element body 1. The filter element fixing plate 2 is provided with through holes 22 for the two-point straight rod interfaces to pass through. The filter element fixing plate 2 is provided with slots 21 that cooperate with the buckles 112. The filter element body 1 and the filter element fixing plate 2 are rotary snap-fitted together.

[0037] The rotary snap-fit ​​filter element has a rotary snap-fit ​​buckle 112 and a slot 21, which can be installed or removed by rotating clockwise or counterclockwise without the need for strong snapping or removal. The buckle 112 and slot 21 are not easily damaged.

[0038] In some embodiments, refer to Figure 2 The buckle 112 includes a horizontal plate 1121, a vertical plate 1122 and a baffle 1123. The inverted L-shape formed by the horizontal plate 1121 and the vertical plate 1122 constitutes an arc-shaped snap-fit ​​channel 1124. One end of the snap-fit ​​channel 1124 is the snap-fit ​​entrance 1125, and the other end of the snap-fit ​​channel 1124 is closed by the baffle 1123. The inner surface of the horizontal plate 1121 is provided with an anti-detachment protrusion 1126.

[0039] In some embodiments, refer to Figure 5 The slot 21 includes a horizontal plate 211, a side plate 213, and a limiting wall 212. The horizontal plate 211 and the side plate 213 form an L-shape that constitutes an arc-shaped slot channel 215. One end of the slot channel 215 is the slot inlet 216, and the other end of the slot channel 215 is closed by the limiting wall 212. The limiting wall 212 prevents the buckle 112 from rotating too far. The direction of the slot inlet 216 is opposite to the direction of the snap-fit ​​inlet 1125. The inner surface of the horizontal plate 211 is provided with an anti-detachment groove 214 to prevent the buckle 112 from detaching in the opposite direction.

[0040] In some embodiments, the anti-detachment protrusion 1126 can be in the shape of a long rib, a dot, or the like. In a specific embodiment, refer to… Figure 2The filter element body 1 is cylindrical, and the anti-detachment protrusions 1126 are long ribs, with the length of the long ribs extending radially along the filter element body 1.

[0041] In some embodiments, refer to Figure 10 The anti-slip protrusions 1126 have a smooth surface.

[0042] In some embodiments, the anti-detachment groove 214 can be in the shape of an elongated groove, a dotted groove, or the like. In a specific embodiment, refer to… Figure 5 With the through hole 22 on the filter element fixing plate 2 as the axial direction, the anti-detachment groove 214 is a long groove, and the length of the long groove extends radially along the through hole 22.

[0043] In some embodiments, refer to Figure 10 The anti-detachment groove 214 has a smooth surface, which makes it easy for the anti-detachment protrusion 1126 to slide in and out.

[0044] In some embodiments, refer to Figure 1 The buckles 112 are evenly distributed. In one specific embodiment, refer to... Figure 1 Two clips 112 are provided. In some other embodiments, there may be three, four, etc.

[0045] In some embodiments, refer to Figure 4 The number of slots 21 and buckles 112 are matched and evenly distributed.

[0046] In some embodiments, refer to Figure 2 The filter element body 1 is composed of a cover plate 11 and a shell 12, and the cover plate 11 and the shell 12 are welded together by a spin welding process.

[0047] In some embodiments, refer to Figure 2 and Figure 3 A latch 112 is provided on the end face of the cover plate 11, and a plurality of evenly distributed protrusions 122 are provided on the end face of the outer shell 12. The protrusions 122 serve as spin-welding limiting points. In a specific embodiment, refer to Figure 3 The number of bumps 122 is four. In some other embodiments, the number of bumps 122 may also be three, five, etc.

[0048] In some embodiments, refer to Figure 7 The two 2-point straight rod interfaces are located at the center of the filter element body 1 and are on the same straight line. In a specific embodiment, the 2-point straight rod interface on one end face of the filter element body 1 is designated as the first 2-point straight rod interface 111, and the 2-point straight rod interface on the other end face of the filter element body 1 is designated as the second 2-point straight rod interface 121. The first 2-point straight rod interface 111 and the second 2-point straight rod interface 121 can be either inlets or outlets, and both can be directly connected to a 2-point standard connector.

[0049] In some embodiments, the 2-point straight rod interface is made of a rigid material, such as steel or PE, which has a certain degree of hardness and can be directly inserted into a 2-point standard connector, which is simple and convenient.

[0050] In some embodiments, the shape of the filter element fixing plate 2 is not limited.

[0051] The filter element installation process of this application is as follows: The snap-fit ​​inlet 1125 of the buckle 112 on the filter element body 1 is aligned with the slot inlet 216 on the filter element fixing plate 2. By rotating the filter element body 1 clockwise or counterclockwise, the side of the snap-fit ​​inlet 1125 of the buckle 112 is fitted against the limiting wall 212 on the slot 21. At the same time, the anti-detachment protrusion 1126 on the buckle 112 is just engaged in the anti-detachment groove 214 on the slot 21 to prevent the filter element body 1 from detaching in the opposite direction. The baffle 1123 on the buckle 112 and the limiting wall 212 on the slot 21 mutually limit each other to prevent over-rotation. To remove the filter element body 1, simply unscrew it clockwise or counterclockwise.

[0052] This embodiment also discloses a drinking water device. The rotary snap-fit ​​filter element can be installed on drinking water devices such as bottled drinking water dispensers, water purifiers, and water purifiers, and has the functions of filtering, purifying, and mineralizing water.

[0053] The above description is only a partial embodiment of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the protection scope of this application.
