Technical Field

[0001] This utility model relates to the field of water level control technology, and in particular to a water level control valve for swimming pools. Background Technology

[0002] Water level control valves are widely used in various automatic water supply systems such as water towers and pools due to their advantages such as light weight, small size, and convenient installation and maintenance.

[0003] Existing water level control valves for swimming pools lack anti-clogging structures during installation and use. Hair and other small impurities in the swimming pool can enter the valve, affecting its operation and causing adverse effects on users. To address the shortcomings of existing technologies, we propose a new water level control valve for swimming pools. Utility Model Content

[0004] The main objective of this invention is to provide a water level control valve for swimming pools, which can effectively solve the problems in the background art.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This water level control valve for swimming pools uses a winding frame and a first filter frame. The water flow impact drives the winding frame to rotate, and the rotation of the winding frame wraps the hair that enters the second filter frame together, preventing the hair from entering the liquid level sensor and water level control valve and affecting the operation of the device.

[0014] 2. This water level control valve for swimming pools, through the setting of a height adjustment screw and a movable frame, etc., is driven by an electric motor to rotate the height adjustment screw, thereby causing the movable frame to change position up and down, so that the liquid level sensor can change height, thus changing the water level of the swimming pool.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figure 1 , Figure 3 as well as Figure 4 As shown, a water level control valve for a swimming pool includes a height adjustment frame 1, a winding frame 15 movably connected to the lower end of a liquid level sensor 14, a bearing 16 disposed between the winding frame 15 and the lower housing of the liquid level sensor 14, a second filter frame 17 detachably connected inside the housing 6, an inlet 3 and an outlet 4 disposed at the upper end of the water level control valve 12, a limit frame 8 fixedly connected to the outer wall of the inlet 3, a first filter frame 7 disposed inside the inlet 3, an anti-slip rubber ring 11 disposed at the upper end of the first filter frame 7, and coarse threads disposed on the outer walls of both the inlet 3 and the outlet 4.

[0022] Through the structure of the winding frame 15 and the first filter frame 7, the winding frame 15 is rotated by the impact of water flow. The rotation of the winding frame 15 will entangle the hair that enters the second filter frame 17 together, so as to prevent the hair from entering the liquid level sensor 14 and the water level control valve 12 and affecting the operation of the device.

[0023] Example 2, as Figures 1-2 As shown, a water level control valve for a swimming pool has an electric motor 2 detachably connected to the upper end of an adjusting frame 1, an adjusting screw 9 detachably connected to the lower end of the electric motor 2, a movable frame 10 threadedly connected to the outer wall of the adjusting screw 9, a fixed frame 5 welded to the right side of the movable frame 10, a housing 6 fixedly connected inside the fixed frame 5, a cover 13 provided at the upper end of the housing 6, a water level control valve 12 provided inside the housing 6, and a liquid level sensor 14 electrically connected to the lower end of the water level control valve 12.

[0024] By using the height adjustment screw 9 and movable frame 10, the electric motor 2 drives the height adjustment screw 9 to rotate, thereby causing the movable frame 10 to change position up and down, so that the liquid level sensor 14 can change its height, thus changing the water level of the swimming pool.

[0025] It should be noted that this utility model is a water level control valve for swimming pools. In use, the motor 2 drives the adjusting screw 9 to rotate, and the adjusting screw 9 drives the movable frame 10 to move up and down, thereby driving the liquid level sensor 14 to move up and down, connecting the inlet 3 to the external water source. When the water level in the swimming pool is low, the water level control valve 12 controls the water source connection. The water is filtered through the first filter frame 7 and flows into the swimming pool through the outlet 4. When the water level in the swimming pool rises and submerges the liquid level sensor 14, the liquid level sensor 14 controls the water level control valve 12 to close, so that the water flow stops from gushing out of the outlet 4. There may be hair in the swimming pool. Small hairs will enter the second filter frame 17. The water flow in the swimming pool impacts the winding frame 15. The winding frame 15 rotates inside the outer shell 6, wrapping the hair that has entered the second filter frame 17 around the outside of the winding frame 15, preventing the hair from entering the liquid level sensor 14 and the water level control valve 12.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
