[0003] The filter element has a service life and needs to be replaced regularly. Currently, when replacing the filter element, it is necessary to first remove the valve head and then take out the filter element. However, the disassembly operation of the valve head is complex and sometimes requires the assistance of professional tools, which makes the replacement operation of the filter element difficult and inefficient. Summary of the Invention

A clamping groove is opened along the circumferential direction of the water pipe, and an installation channel for inserting the water pipe is opened on the valve head; the disassembly and assembly structure further includes a support seat for supporting each of the clamping seats. The two support seats are respectively installed on the valve head. Each of the support seats is provided with a through hole communicating with the installation channel. The length direction of each of the through holes is arranged along the first direction, and each of the clamping plates is disposed in the corresponding through hole.

[0019] With the above structure, the support for the clamping seat can be realized through the support seat; the limiting and guiding of the clamping plate can be realized through the through hole; when the clamping plate enters and exits the installation channel, it can cooperate with the clamping groove to realize clamping, and further realize the connection and fixation between the filter barrel and the valve head.

[0022] In one embodiment, a connection channel communicating with the installation channel is further opened on the valve head, and a sleeve communicating with the connection channel is installed on the outer peripheral surface of the valve head.

[0023] With the above structure, connection with external objects can be achieved through two sleeves, realizing water inlet and outlet, and further realizing the filtering operation.

[0024] In one embodiment, the end surface of each clamping plate away from the corresponding guide rod is arc-shaped.

[0025] With the above structure, the arc-shaped end surfaces on each clamping plate can be adapted to the card slots on the water pipe, realizing effective clamping cooperation between the clamping plate and the water pipe.

[0026] In one embodiment, the disassembly and assembly structure further includes a limit baffle for limiting the moving stroke of the handle, and the limit baffle is installed on the valve head.

[0027] With the above structure, the limit baffle can prevent the handle from detaching from the valve head when moving in the second direction; moreover, the handle can cooperate with the limit baffle to drive the valve head to move, realizing the detachment of the valve head from the filter barrel.

[0054] Please refer to Figures 1 to 3 , and now the disassembly and assembly structure provided by the embodiment of the present application will be described. The disassembly and assembly structure includes a valve head 1, a filter barrel 2 for accommodating a filter element, two clamping seats 3 slidably mounted on the valve head 1 along the first direction, and a handle 4 slidably mounted on the valve head 1 along the second direction. Both ends of the handle 4 are respectively abutted against the two clamping seats 3. The handle 4 is used to control the two clamping seats 3 to approach each other to clamp and fix the filter barrel 2, and to control the two clamping seats 3 to move away from each other to release the clamping of the filter barrel 2, facilitating the disassembly between the filter barrel 2 and the valve head 1. In this structure, in the present application, two clamping seats 3 are slidably mounted on the valve head 1 along the first direction, and a handle 4 is slidably mounted on the valve head 1 along the second direction. The handle 4 can control the two clamping seats 3 to approach or move away from each other. When the handle 4 controls the two clamping seats 3 to approach each other, the two clamping seats 3 can clamp and fix the filter barrel 2. When the handle 4 controls the two clamping seats 3 to move away from each other, the two clamping seats 3 can release the clamping of the filter barrel 2. Compared with the traditional disassembly and assembly method of the filter element, in the present application, it is not necessary to disassemble the valve head 1. Only by controlling the two clamping seats 3 through the handle 4 can the disassembly and assembly between the filter barrel 2 and the valve head 1 be realized. The disassembly and assembly of the filter barrel 2 and the filter element are convenient, fast, time-saving, labor-saving, and efficient.

In this structure, on the one hand, the reliability of the handle 4 to control the two clamping seats 3 to approach and move away from each other can be improved. On the other hand, the occupied space of the disassembly and assembly structure in the first direction or the second direction can be reduced, thereby reducing the overall volume of the disassembly and assembly structure and the water purification device.

Wherein, the length direction of each guide groove 411 is inclined to the horizontal plane; the two guide grooves 411 are symmetrically distributed with respect to the central axis of the connecting block 42.

With this structure, when the handle 4 moves upward along the second direction, the two clamping seats 3 are controlled to move away from each other, unlocking the filter barrel 2, and the filter barrel 2 can be detached from the valve head 1. At this time, the limit baffle 5 can block the handle 4 to prevent it from detaching from the valve head 1 due to excessive moving stroke of the handle 4. Moreover, the handle 4 can cooperate with the limit baffle 5 to drive the valve head 1 to move, realizing the separation of the valve head 1 from the filter barrel 2.

[0068] The disassembly and assembly between the filter cartridge 2 and the valve head 1 provided in the embodiments of the present application are divided into a disassembly step and an installation step. Among them, the disassembly step is specifically as follows: the handle 4 moves upward along the second direction under the action of an external force, and the guide grooves 411 on the two sliding blocks 41 can respectively push the two guide rods 31 to move along the first direction and make the two guide rods 31 move away from each other. The two guide rods 31 drive the clamping plates 32 to move away from each other, and each clamping plate 32 disengages from the clamping groove 211 on the water pipe 21, thereby realizing the separation between the filter cartridge 2 and the valve head 1 and realizing the disassembly of the filter cartridge 2.

[0069] The installation step is specifically as follows: the water pipe 21 on the filter cartridge 2 is inserted into the installation channel 12, the handle 4 moves downward along the second direction under the action of an external force, and the guide grooves 411 on the two sliding blocks 41 can respectively push the two guide rods 31 to move along the first direction and make the two guide rods 31 move closer to each other. The two guide rods 31 drive the clamping plates 32 to move closer to each other and make each clamping plate 32 snap into the corresponding clamping groove 211. When each guide rod 31 slides into the corresponding positioning groove 412, the handle 4 is clamped and fixed to the valve head 1, and the clamping seat 3 realizes the clamping of the water pipe 21, thereby realizing the installation between the filter cartridge 2 and the valve head 1.
