[0002] In the swimming pool water treatment system, the filter plays a vital role, and the top valve device is a key component of the filter. Its performance directly affects the operation effect and stability of the entire filtration system.

[0003] During use, the existing swimming pool filter top valve device is usually installed by threaded connection with the connecting pipe. If the threaded connection is not tightened enough, it may cause a loose seal; if it is overtightened, it may damage the threads or cause the pipe to deform, affecting the normal flow performance of the pipe. In addition, when the swimming pool filter top valve device or the connecting pipe needs to be maintained, repaired or replaced, the disassembly of the threaded connection is relatively complicated. Due to long-term use, the threads may rust or get stuck, making the disassembly process difficult. Therefore, we have introduced a new swimming pool filter top valve device. Utility Model Content

[0027] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0028] A top valve device for a swimming pool filter, comprising a valve body 1. A water inlet pipe 2 is fixedly connected to the upper right part of the outer surface of the valve body 1, and a water outlet pipe 3 is fixedly connected to the lower left part of the outer surface of the valve body 1. One end of the water inlet pipe 2 far from the valve body 1 and one end of the water outlet pipe 3 far from the valve body 1 are both fixedly connected with a connection mechanism 4. A positioning mechanism 5 is snap-connected to the outer surfaces of the two connection mechanisms 4. A first connection pipe 6 is fixedly connected to the right end of the positioning mechanism 5 on the right side, and a second connection pipe 7 is fixedly connected to the left end of the positioning mechanism 5 on the left side.

[0029] In this embodiment, the connection mechanism 4 includes a connection block 41. Positioning grooves 42 are formed in both the upper and lower parts of the outer surface of the connection block 41. Moving grooves 43 are formed in both the front and rear parts of the inside of the connection block 41. Springs 44 are fixedly connected to the inner walls of the two moving grooves 43. One end of each of the two springs 44 far from the inner wall of the moving groove 43 is fixedly connected with a connection piece 45. One end of each of the two connection pieces 45 far from the spring 44 is fixedly connected with a limiting rod 46. The right end of the connection block 41 is fixedly connected to the water outlet pipe 3, and the connection block 41 is in communication with the inside of the valve body 1 through the water outlet pipe 3. The outer surfaces of the two connection pieces 45 are movably connected to the inner walls of the two moving grooves 43 respectively. One end of each of the two limiting rods 46 close to the connection piece 45 is inserted into the two moving grooves 43 respectively.

[0030] Through the above scheme: By placing the positioning block 51 on the first connection pipe 6 on the right side of the water inlet pipe 2, applying force to the two limiting rods 46 to make the two limiting rods 46 move into the two moving grooves 43 respectively and squeeze the springs 44 through the connection pieces 45, and then seamlessly snap-connecting the connection block 41 into the connection groove 52. Under the elastic reset of the springs 44, the two limiting rods 46 automatically pop out from the two limiting holes 55, making the connection between the first connection pipe 6 and the water inlet pipe 2 convenient and fast. The connection method of the second connection pipe 7 and the water outlet pipe 3 is the same, making the connection and installation between the top valve device and the external connection pipe convenient and fast, and also convenient and fast to disassemble for maintaining, repairing or replacing the top valve device of the swimming pool filter or the connection pipe.

[0031] In this embodiment, the positioning mechanism 5 includes a positioning block 51. A connection groove 52 is formed in the right end of the positioning block 51. Positioning strips 53 are fixedly connected to both the upper and lower parts of the inner wall of the connection groove 52. A sealing ring 54 is arranged inside the connection groove 52. Limiting holes 55 are formed in both the front and rear parts of the outer surface of the positioning block 51. The left end of the positioning block 51 is fixedly connected to the second connection pipe 7. The connection groove 52 is snap-connected to the connection block 41. The two positioning strips 53 are snap-connected to the two positioning grooves 42 respectively. The sealing ring 54 is in close fit with the connection block 41.

[0032] Through the above solution: when the connecting block 41 is snapped into the connecting groove 52, the two positioning grooves 42 on the connecting block 41 are respectively snapped with the two positioning bars 53 in the connecting groove 52, so that the two limiting rods 46 can quickly correspond to the positions of the two limiting holes 55, which can improve the installation and connection efficiency. And when the connecting block 41 is completely snapped into the connecting groove 52, the connecting block 41 is closely attached to the sealing ring 54, which can improve the connection sealing performance.

[0033] It should be noted that the present utility model is a top valve device for a pool filter. During use, the positioning block 51 on the first connecting pipe 6 is placed on the right side of the water inlet pipe 2. Subsequently, a force is applied to the two limiting rods 46 to cause them to move into the two movable grooves 43 respectively, and the spring 44 is compressed through the action of the connecting piece 45. Then, the connecting block 41 is seamlessly inserted into the connecting groove 52. Under the elastic force of the spring 44, the two limiting rods 46 will automatically pop out from the two limiting holes 55, thus simply and quickly realizing the connection between the first connecting pipe 6 and the water inlet pipe 2. The same connection method is also applicable to the second connecting pipe 7 and the water outlet pipe 3, making the connection and installation of the top valve device with the external connecting pipe convenient and rapid, and also facilitating subsequent disassembly, maintenance, inspection or replacement work. During the process of the connecting block 41 being inserted into the connecting groove 52, the two positioning grooves 42 on the connecting block 41 will be snapped with the two positioning bars 53 in the connecting groove 52, which can ensure that the two limiting rods 46 quickly and accurately correspond to the positions of the two limiting holes 55, thereby improving the installation and connection efficiency. And when the connecting block 41 is completely inserted into the connecting groove 52, the connecting block 41 will be closely attached to the sealing ring 54, which can effectively improve the connection sealing performance.
