When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0036] The present invention proposes a snap-fit ​​assembly 100, comprising: a snap-fit ​​base 110 having a mounting cavity 111 for plug-in connection, a snap ring 130 rotatably connected within the mounting cavity 111, a limiting structure 131 provided on the inner side of the snap ring 130, and a driving block 132 provided on the side of the snap ring 130 facing the opening of the mounting cavity 111; and a connecting body 120, comprising a protrusion 121 and a top block 122; when the connecting body 120 is inserted into the snap-fit ​​base 110, the protrusion 121 is located at the end of the limiting structure 131 away from the opening of the mounting cavity 111, and the top block 122 is used to drive the driving block 132 to rotate, so that after the snap ring 130 rotates, the limiting structure 131 snaps into the protrusion 121.

[0037] In one embodiment, such as Figure 1-6As shown, the snap-fit ​​assembly 100 includes a snap-fit ​​base 110 and a connector 120. The snap-fit ​​base 110 is inserted into the connector 120. The snap-fit ​​base 110 has a mounting cavity 111 for installation. A retaining ring 130 is rotatably disposed in the mounting cavity 111, and a limit structure 131 is provided on the inner side of the retaining ring 130. A driving block 132 is provided on the side of the retaining ring 130 facing the opening of the mounting cavity 111. The connector 120 is provided with a protrusion 121 and a top block 122. The protrusion 121... The top block 122 can abut against the limiting structure 131, and can engage with the driving block 132. When the connecting body 120 is inserted into the mounting cavity 111 of the snap-fit ​​seat 110, the protrusion 121 moves from the side of the limiting structure 131 to the end of the limiting structure 131 away from the opening of the mounting cavity 111. As the connecting body 120 gradually penetrates deeper into the mounting cavity 111, the driving block 132, which is provided on the side of the snap ring 130 facing the opening of the mounting cavity 111, abuts against the top block 122. When the side of 131 moves to the end of the limiting structure 131 away from the opening of the mounting cavity 111, the top block 122 contacts the protruding part opposite to the driving block 132. As the connector 120 gradually penetrates into the locking seat 110, the top block 122 will push the retaining ring 130 to rotate by contacting the driving block 132. After the retaining ring 130 rotates, the limiting structure 131 provided on the inner side of the retaining ring 130 is displaced. At this time, the limiting structure 131 limits and locks the protrusion 121, thereby making the connector... The connector 120 is locked in place within the mounting cavity 111 of the mounting base 110. This design allows the connector 120 to be installed into the mounting cavity 111 of the mounting base 110 without manually rotating the connector 120 or the mounting base 110. Instead, the connector 120 or the mounting base 110 can be manually pushed up and down along the opening direction of the mounting cavity 111 to achieve the locking mechanism. This makes it easier and more convenient to lock the connector 120 into the mounting cavity 111 of the mounting base 110.

[0038] Specifically, multiple limiting structures 131 are provided, which surround the inner side of the retaining ring 130 and are spaced apart. For example... Figure 1-6As shown, multiple limiting structures 131 are provided, which surround the inner side of the retaining ring 130 and are spaced apart from each other. The spaced-apart arrangement between adjacent limiting structures 131 forms a insertion groove. When the connector 120 is installed into the mounting cavity 111 of the retaining seat 110, the protrusion 121 provided on the connector 120 can be inserted into the retaining seat 110 along the insertion groove. Then, as described above, when the top block 122 abuts against the driving block 132, the top block 122 will drive the retaining ring 130 to rotate through the driving block 132 when coupled with the driving block 132, causing the multiple limiting structures 131 to displace and the limiting structures 131 to support the protrusion 121, thereby achieving the purpose of retaining the retaining seat 110 and the connector 120 engaging.

[0039] More specifically, the limiting structure 131 includes a first fixing part 1311 and a second fixing part 1312, the first fixing part 1311 and the second fixing part 1312 are fixedly connected, and the second fixing part 1312 is used to stop the first fixing part 1311. Figure 4 and Figure 5 As shown, the limiting structure 131 includes a first fixing part and a second fixing part 1312. The first fixing part 1311 and the second fixing part 1312 are fixedly connected, and the second fixing part 1312 can stop the first fixing part 1311. One side of the first fixing part 1311 is at the same height as one side of the second fixing part 1312, while the other side of the first fixing part 1311 is lower than the height of the second fixing part 1312, and the other side of the first fixing part 1311 is fixedly connected to one side of the second fixing part 1312. Therefore, the second fixing part 1312 has a stopping effect on the first fixing part 1311, so that the limiting structure 131 can better limit and engage the protrusion 121, and make the engagement seat 110 and the connecting body 120 more firmly engaged. It is worth mentioning that the first fixing part 1311 is fixedly connected to the driving block 132. This setting can further improve the firmness of the first fixing part 1311 and the driving block 132 themselves.

[0040] Furthermore, the first fixing part 1311 has a first inclined surface 131a at the end facing the bottom of the cavity of the locking seat 110, and the first inclined surface 131a is inclined from top to bottom towards the end near the second fixing part 1312. Figure 4 and Figure 5 As shown, in order to enable the first fixing part 1311 and the second fixing part 1312 to better engage with the protrusion 121, a first inclined surface 131a is provided at one end of the first fixing part 1311 facing the bottom of the cavity of the engaging seat 110. The first inclined surface 131a is arranged from top to bottom with the first fixing part 1311 on one side and the other side on the other side. The first inclined surface 131a can better cooperate with the second fixing part 1312 to achieve limiting engagement with the limiting structure 131.

[0041] In order to make the protrusion 121 easier to remove from the insertion slot on the side of the second fixing part 1312, therefore, Figure 4 and Figure 5 As shown, the second fixing part 1312 has a second inclined surface 131b at one end facing the bottom of the cavity of the locking seat 110. The second inclined surface 131b is inclined from top to bottom towards the end away from the first fixing part 1311. The second inclined surface 131b is provided on the second fixing part 1312. The angle of the second inclined surface 131b is the same as that of the first inclined surface 131a. The second inclined surface 131b can guide the protrusion 121 when it contacts the second inclined surface 131b, so that the protrusion 121 can be better disengaged from the insertion slot under the guidance of the second inclined surface 131b.

[0042] In one embodiment, the end of the protrusion 121 facing the top block 122 is provided with an abutment surface, which is inclined and abuts against a first inclined surface 131a or a second inclined surface 131b. Figure 3 As shown, the end of the protrusion 121 facing the top block 122 has an abutment surface, which is also inclined, and the inclination angle is the same as that of the first inclined surface 131a and the second inclined surface 131b. When the protrusion 121 is inserted into the mounting cavity 111 of the snap-fit ​​groove along the connector 120, the retaining ring 130 rotates under the push of the top block 122, and the abutment surface of the protrusion 121 partially contacts the first inclined surface 131a. When the abutment surface of the protrusion 121 partially contacts the first inclined surface 131a, the protrusion 121 will completely abut against the first inclined surface 131a due to the influence of external force. When the protrusion 121 completely abuts against the first inclined surface 131a, it will push the retaining ring 130 to rotate again, so that the driving block 132 and the top block 122 form a protruding point facing each other again. At this time, it is only necessary to To push the connector 120 upwards again or press the snap-fit ​​seat 110 downwards, the top block 122 will again abut against the drive block 132. The top block 122 will then abut against the drive block 132 to push the snap ring 130 to rotate. When the snap ring 130 rotates again, the protrusion 121 will disengage from the first inclined surface 131a to bring the second inclined surface 131b to its position. At this time, the protrusion 121 can pass through the second inclined surface 131b to the insertion slot and then disengage through the insertion slot, thereby separating the connector 120 from the snap-fit ​​seat 110. This design allows the connector 120 to be installed into or removed from the snap-fit ​​seat 110 by pressing up and down, making the operation easier and more convenient, and allowing for better disassembly and installation of the connector 120 in spaces with limited space.

[0043] Specifically, the length of the first inclined surface 131a is greater than the length of the abutting surface, and when the abutting surface abuts against the first inclined surface 131a, the protrusion 121 drives the retaining ring 130 to rotate. For example... Figure 4 and Figure 5 As shown, the length of the first inclined surface 131a is set to be greater than the length of the abutting surface. This allows for better contact between the abutting surface and the first inclined surface 131a, which in turn pushes the retaining ring 130 to rotate. This ensures that the driving block 132 at the bottom of the retaining ring 130 and the top block 122 on the connector 120 are in a state where their protruding points are opposite each other. This allows the top block 122 to push the retaining ring 130 to rotate again when it contacts the driving block 132, thereby enabling the disassembly and installation of the connector 120.

[0044] In one embodiment, the drive block 132 is a drive tooth, and the top block 122 engages with the drive tooth when it comes into contact. Figure 4 As shown, in this embodiment, the driving block 132 is a driving tooth, and the top block 122 is also a tooth that meshes with the driving tooth. The protrusion of the driving tooth and the top block 122 is a tip. Of course, in other embodiments, the driving block 132 can be a convex arc shape, and the top block 122 can be a concave arc shape that matches the convex arc shape.

[0045] In one embodiment, the snap-fit ​​assembly 100 further includes a first elastic member 140, which is disposed between the snap-fit ​​seat 110 and the snap ring 130, thereby distancing the snap-fit ​​seat 110 and the snap ring 130 from each other. Figure 2 and Figure 3 As shown, the mounting cavity 111 of the snap-fit ​​seat 110 is provided with a slot for mounting the first elastic element 140. The first elastic element 140 is disposed in the slot and abuts against the snap ring 130, which is also disposed in the mounting cavity 111. The first elastic element 140 does not affect the rotation of the snap ring 130, but only makes the bottom of the cavity of the snap-fit ​​seat 110 and the snap ring 130 move away from each other. The snap ring 130 abuts against the protrusion 121 on the connector 120 at a position near the opening of the mounting cavity 111.

[0046] Specifically, the snap-fit ​​assembly 100 also includes a second elastic element 150, which is disposed between the snap-fit ​​base 110 and the connector 120, thereby distancing the snap-fit ​​base 110 and the connector 120 from each other. Figure 2As shown, a second elastic element 150 is also provided in the mounting cavity 111 of the snap-fit ​​base 110. The second elastic element 150 is located at the bottom of the mounting cavity 111 of the snap-fit ​​base 110. It is mainly used to abut against the connector 120 inserted into the mounting cavity 111. It also pushes the connector 120 to move out of the mounting cavity 111, so that the protrusion 121 provided on the connector 120 can better engage with the limiting structure 131. At the same time, when the protrusion 121 is partially engaged with the limiting structure 131, it can push the protrusion 121 to fully engage with the limiting part, so as to push the snap ring 130 to rotate. The driving block 132 provided at the bottom of the snap ring 130 and the top block 122 maintain a state where the protruding points are opposite each other, which makes it easy to remove the connector 120 that is snapped into the snap-fit ​​base 110.

[0047] In one embodiment, the two sides of the limiting structure 131 are inclined towards the middle of the limiting structure 131 along the protruding direction. For example Figure 5 As shown, the two sides of the limiting structure 131 are inclined towards the middle of the limiting structure 131 along the protruding direction. That is, one side surface of the first fixing part 1311 and the other side surface of the second fixing part 1312 are inclined towards each other. The limiting structure 131 configured in this way increases the gap between the insertion grooves formed between adjacent limiting structures 131, so that the protrusion 121 provided on the connector 120 can pass through the insertion groove more smoothly and be located at the top of the limiting structure 131 to achieve a snap-fit ​​with the limiting structure 131.

[0048] Specifically, the two sides of the protrusion 121 are inclined towards the center of the protrusion 121 along the protruding direction. For example... Figure 3 As shown, the two sides of the protrusion 121 are inclined towards the middle of the protrusion 121 along the protrusion direction. The protrusion 121 is arranged in this way to better match the setting of the limiting structure 131, so that the protrusion 121 can be inserted into the mounting cavity 111 of the card holder 110 in conjunction with the insertion groove formed between the adjacent limiting structures 131.

[0049] The present invention also proposes a filter element 200, which includes a snap-fit ​​assembly 100. The specific structure of the snap-fit ​​assembly 100 is as described in the above embodiments. Since the filter element 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0050] Specifically, such as Figure 7As shown, the filter element 200 also includes a connecting member 210, which is detachably connected to the snap-fit ​​base 110. The connecting member 210 has a through hole that communicates with the filter element 200. Since the filter element 200 is used to filter liquids or gases, a connecting member 210 is detachably connected to the snap-fit ​​base 110. The connecting member 210 has a through hole for communicating with the filter element 200. This design allows the filter element 200 to be easily and quickly snapped into place in a confined space.

[0051] 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 using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
