[0002] Currently, there are two main methods for connecting filter cartridges and decorative caps on the market: one is a screw connection, which takes a long time to tighten, resulting in low installation efficiency; the other is a snap-fit ​​connection, which requires aligning the filter cartridge's snaps with the decorative cap's snap positions and applying considerable external force to lock them in place. Therefore, to save effort, tools are often used to tap the decorative cap for quick installation, posing a risk of damage. Thus, existing decorative cap installation methods suffer from cumbersome operation and low installation efficiency. Utility Model Content

[0003] The main purpose of this application is to propose a cover installation structure and filter element assembly, which aims to solve the problems of cumbersome installation operation and low installation efficiency in the existing decorative cover installation method.

The snap fastener is connected to one end of the elastic element, and the elastic element is used to move the snap fastener within the cavity. The second fastener is located at the first opening. The end of the snap fastener away from the elastic element is used to engage with one end of the second fastener, and the other end of the second fastener is used to connect to the filter element.

[0007] In one embodiment, the end of the buckle away from the elastic element has an inclined surface, the inclined surface facing the first opening; the end of the buckle with the inclined surface is used to fasten with a corresponding second fastener on the filter element.

[0008] In one embodiment, the second fastener is provided with a slot, and the end of the buckle away from the elastic member is engaged in the slot to achieve fastening.

[0009] In one embodiment, the end of the second fastener is provided with an arc-shaped protrusion, which is used to abut against the inclined surface to push the buckle to move in a direction perpendicular to the axis of the second fastener.

[0010] In one embodiment, the cavity includes an insertion hole, a clearance groove, and a guide groove. The insertion hole and the clearance groove are interconnected and located on the same axis. The insertion hole has a first opening at one end away from the clearance groove. The guide groove intersects with the insertion hole and / or the clearance groove. The second fastener is located inside the insertion hole. The elastic element and the snap fastener are located inside the guide groove. The snap fastener extends out of the insertion hole at one end away from the elastic element and engages with the second fastener.

[0011] In one embodiment, the insertion hole extends along the axial direction of the cover body; and / or,

[0012] The guide groove extends radially along the cover body, is perpendicular to the insertion hole, and is located at the junction of the insertion hole and the clearance groove.

[0013] In one embodiment, the elastic element includes a spring, one end of which is connected to the inner wall of the guide groove, and the other end of the elastic element is connected to the snap fastener.

[0014] In one embodiment, the cover body has an extension portion surrounding the side with the first opening, the extension portion forming a groove, the groove communicating with the first opening, the groove being used to accommodate the end of the filter element; the sidewall of the groove abuts against the outer periphery of the filter element, and the bottom wall of the groove abuts against the end face of the filter element.

[0029] Currently, there are two main methods for connecting filter cartridges and decorative caps on the market: one is a screw connection, which takes a long time to tighten, resulting in low installation efficiency; the other is a snap-fit ​​connection, which requires aligning the filter cartridge's snaps with the decorative cap's snap positions and applying considerable external force to lock them in place. Therefore, to save effort, tools are often used to tap the decorative cap for quick installation, posing a risk of damage. Thus, existing decorative cap installation methods suffer from cumbersome operation and low installation efficiency.

[0030] To address the aforementioned problems, this application proposes a cover mounting structure.

[0031] Please see Figures 1 to 3 In one embodiment of this application, the cover mounting structure includes a cover body 1 and a locking assembly 2. The cover body 1 has a cavity 11 inside, and the cavity 11 has a first opening 12. The locking assembly 2 is disposed in the cavity 11 and includes a first fastener 21 and a second fastener 22. The first fastener 21 includes a snap fastener 211 and an elastic member 212. One end of the snap fastener 211 is connected to one end of the elastic member 212, and the elastic member 212 is used to drive the snap fastener 211 to move within the cavity 11. The second fastener 22 is located at the first opening 12. One end of the snap fastener 211 away from the elastic member 212 is used to fasten with one end of the second fastener 22, and the other end of the second fastener 22 is used to connect with the filter element 3.

[0032] A cavity 11 is provided inside the cover body 1, and a locking assembly 2 is provided inside the cavity 11 to achieve the installation connection between the cover body 1 and the filter element 3. The locking assembly 2 includes a first fastener 21 and a second fastener 22. The first fastener 21 includes a snap fastener 211 and an elastic element 212, and the second fastener 22 is connected to the filter element 3. By utilizing the elastic element 212 to move the snap fastener 211 within the cavity 11, the elastic element 212 drives the snap fastener 211 to move and engage with the second fastener 22, thereby achieving the purpose of installing the cover body 1 onto the filter element 3. The elastic element 212 not only drives the snap fastener 211 to move within the cavity 11, but also reduces the force required by the user when installing the cover body 1, making the installation operation more effortless. This cover installation structure makes the cover body 1 easier to install, reduces the difficulty of operation and installation, and improves installation efficiency. In addition, by providing a cavity 11 inside the cover body 1, a built-in space is provided for the locking assembly 2, which has a protective function for the locking assembly 2. The cover installation structure utilizes the interaction between the elastic element 212 and the buckle 211 to achieve quick, easy, and labor-saving installation and disassembly of the first fastener 21 and the second fastener 22, solving the problems of cumbersome and inefficient traditional decorative cover installation operations.

[0033] In one embodiment, the second fastener 22 is provided with a slot 221, and the end of the buckle 211 away from the elastic member 212 is engaged in the slot 221 to achieve fastening. In the above structure, the second fastener 22 is provided with a slot 221, and the buckle 211 is engaged in the slot 221 to achieve fastening. Through the cooperation of the slot 221 and the buckle 211, the cover body 1 and the filter element 3 can be installed without additional tools, which simplifies the installation operation steps of the cover body 1 and the filter element 3, reduces the installation difficulty, and improves the installation efficiency. Secondly, through the cooperation of the slot 221 and the buckle 211, the buckle 211 can be accurately aligned with the second fastener 22, ensuring the accuracy and stability of the connection between the first fastener 21 and the second fastener 22. In addition, the cooperation of the slot 221 and the buckle 211 can provide good mechanical locking, increasing the strength and reliability of the connection between the first fastener 21 and the second fastener 22.

[0034] In one embodiment, the end of the buckle 211 away from the elastic member 212 has an inclined surface 2111, which faces the first opening 12. The end of the buckle 211 with the inclined surface 2111 is used to fasten with the corresponding second fastener 22 on the filter element 3. The inclined surface 2111 at the end of the buckle 211 away from the elastic member 212 faces the direction of the first opening 12, so that the second fastener 22 can extend into the cavity 11 through the first opening 12 and abut against the inclined surface 2111. During installation, an external force is applied to the cover body 1 to abut against the inclined surface 2111 at one end of the second fastener 22. The second fastener 22 uses the angle of the inclined surface 2111 to transmit force to push the buckle 211 to move. As the buckle 211 is pushed, the connection to the filter element 3 is fastened. The elastic element 212 on buckle 211 is compressed and stores elastic potential energy. The second fastener 22 continues to push buckle 211 until the first opening 12 of the slot 221 faces buckle 211. Under the elastic force provided by the elastic element 212, the end of buckle 211 is pushed into the slot 221 of the second fastener 22, thus achieving fastening. After buckle 211 is fully inserted into the slot 221, the elastic force of the elastic element 212 ensures that buckle 211 is firmly fixed in the slot 221, thus completing the fastening.

[0035] In the above structure, the cooperation of the buckle 211 and the slot 221 enables self-locking, improving the stability and security of the connection between the first fastener 21 and the second fastener 22. The user only needs to apply external force to push the cover to complete the connection between the first fastener 21 of the cover body 1 and the second fastener 22 of the filter element 3, without the need for complicated operations or tools. In addition, the compression and release of the elastic element 212 provides a buffering effect, reducing the impact and wear between the first fastener 21 and the second fastener 22 during installation.

[0036] In one embodiment, the end of the second fastener 22 is provided with an arc-shaped protrusion 222, which is used to abut against the inclined surface 2111 to push the buckle 211 to move in a direction perpendicular to the axis of the second fastener 22. When the arc-shaped protrusion 222 abuts against the inclined surface 2111, the arc-shaped surface of the arc-shaped protrusion 222 can smoothly transmit force along the inclined surface 2111, so that the second fastener 22 can reduce the loss of force when pushing the buckle 211.

[0037] In one embodiment, the cavity 11 includes an insertion hole 111, a clearance groove 112, and a guide groove 113. The insertion hole 111 and the clearance groove 112 are interconnected and located on the same axis. The end of the insertion hole 111 away from the clearance groove 112 is provided with a first opening 12. The guide groove 113 intersects with the insertion hole 111 and / or the clearance groove 112. A second fastener 22 is provided in the insertion hole 111. An elastic member 212 and a buckle 211 are provided in the guide groove 113. The end of the buckle 211 away from the elastic member 212 extends into the insertion hole 111 and engages with the second fastener 22. The insertion hole 111 is the channel through which the second fastener 22 extends into the cavity 11 and engages with the first fastener 21, allowing the second fastener 22 to smoothly pass through the first opening 12 into the cavity 11 and engage with the buckle 211. The clearance groove 112 is connected to the insertion hole 111 and is located on the same axis, providing clearance space when the second fastener 22 pushes the buckle 211. At the same time, when the end of the buckle 211 is engaged in the slot 221, the arc-shaped protrusion 222 is located in the clearance groove 112. The guide groove 113 intersects with the insertion hole 111 and / or the clearance groove 112, and is used to guide the elastic member 212 and the buckle 211 to maintain the correct position, and to provide the correct guide movement path during movement. During the fastening process, the arc-shaped protrusion 222 of the second fastener 22 first abuts against the inclined surface 2111 of the buckle 211, pushing the buckle 211 to move along the guide groove 113; as the second fastener 22 continues to push, the buckle 211 is compressed by the elastic element 212 and moves along the guide groove until the end of the buckle 211 is engaged in the slot 221 of the second fastener 22; the elastic element 212 then releases the compression energy to ensure that the buckle 211 is firmly fixed in the slot 221, completing the fastening.

[0038] In one embodiment, the insertion hole 111 extends along the axial direction of the cover body 1. The extension of the insertion hole 111 along the axial direction helps to maintain the structural symmetry and alignment of the cover body 1, helps to evenly distribute the force applied to the cover body 1, and improves the structural stability of the cover body 1.

[0039] In one embodiment, the guide groove 113 extends radially along the cover body, is perpendicular to the insertion hole 111, and is located at the junction of the insertion hole 111 and the clearance groove 112. The guide groove 113 extends radially along the cover body, meaning it extends outward from the insertion hole 111 at the center of the cover body 1, forming a guide installation channel from the center to the edge, which guides the buckle 211 and the elastic member 212 to move in the correct direction. The guide groove 113 is located at the junction of the insertion hole 111 and the clearance groove 112, allowing the buckle 211 to smoothly engage with the slot 221 of the second fastener 22 within the insertion hole 111 when pushed.

[0040] In one embodiment, the elastic element 212 includes a spring, one end of which is connected to the inner wall of the guide groove 113, and the other end of the elastic element 212 is connected to the snap fastener 211. One end of the spring is fixed to the inner wall of the guide groove 113 to ensure that the spring can stably extend and retract along the direction of the guide groove 113 when subjected to force; the other end of the spring is connected to the snap fastener 211, and when the snap fastener 211 needs to move to achieve fastening or unlocking, the extension and retraction of the spring can provide the necessary force to push or pull the snap fastener 211.

[0041] In one embodiment, an extension 13 is provided around the side of the cover body 1 where the first opening 12 is located. The extension 13 forms a groove 14 around the opening 12. The groove 14 communicates with the first opening 12 and is used to accommodate the end of the filter element 3. The sidewall of the groove 14 abuts against the outer periphery of the filter element 3, and the bottom wall of the groove 14 abuts against the end face of the filter element 3. The extension 13 is provided around the side of the cover body 1 where the first opening 12 is located, and the extension 13 forms a groove 14 around the opening 12. The groove 14 communicates with the first opening 12, so that the groove 14 can accommodate the end of the filter element 3, providing a stable installation position for the filter element 3. The sidewall of the groove 14 abuts against the outer periphery of the filter element 3, and the bottom wall of the groove 14 abuts against the end face of the filter element 3, improving the connection stability between the filter element 3 and the cover body 1.

[0042] In one embodiment, the locking assembly 2 includes at least two first fasteners 21, which are located on opposite sides of the cavity 11. By providing the first fasteners 21 on opposite sides of the cavity 11, the stability and balance of the entire locking assembly 2 can be enhanced, which helps to distribute the force evenly and reduce structural deformation or damage caused by eccentric force. The two first fasteners 21 can lock the second fastener 22 from two opposite directions, so that the locking structure can provide a stronger locking force and increase the connection reliability between the cover body 1 and the filter element 3.

[0043] In one embodiment, a second opening 15 is provided on the side of the cavity 11 away from the main opening, and a cover 16 is provided at the second opening 15. By adding the second opening 15, the elastic element 212 and the snap fastener 211 can be installed into the cavity 11, making the installation, maintenance and replacement of the elastic element 212 and the snap fastener 211 simpler; while the presence of the cover 16 can prevent external dust and contaminants from entering the cavity 11, protecting the cleanliness of the cavity 11. It should be noted that the clearance groove 112 is provided on the side of the cover 16 facing the cavity 11.

[0044] The technical solution of this application achieves the installation connection between the cover body 1 and the filter element 3 by setting a cavity 11 inside the cover body 1 and setting a locking component 2 inside the cavity 11. The locking component 2 includes a first fastener 21 and a second fastener 22. The first fastener 21 includes a snap fastener 211 and an elastic element 212. The second fastener 22 is connected to the filter element 3. By utilizing the elastic element 212 to move the snap fastener 211 inside the cavity 11, the elastic element 212 drives the snap fastener 211 to move and engage with the second fastener 22, thereby achieving the purpose of installing the cover body 1 onto the filter element 3. The elastic element 212 not only drives the snap fastener 211 to move inside the cavity 11, but also reduces the force required by the user when installing the cover body 1, making the installation operation more labor-saving. This cover installation structure makes the cover body 1 easier to install, reduces the difficulty of operation and installation, and improves installation efficiency.
