DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4The utility model provides a technical solution: a water-saving valve, including a water-saving valve 1, one end of the water-saving valve 1 is connected to a water inlet pipe 2, and the other end of the water-saving valve 1 is connected to a faucet 3. The water-saving valve 1 includes a valve body 4, and the valve body 4 has a valve core 5 built therein. One end of the valve core 5 is connected to a driving rod 6, and the end of the driving rod 6 is connected to a floating ball 7. A guide base 8 is provided on the valve body 4, and the driving rod 6 penetrates the guide base 8 and is slidably connected to the guide base 8. The water-saving valve 1 is installed on the water inlet pipe 2 and is placed between the water inlet pipe 2 and the faucet 3 for use. When the floating ball 7 contacts the water surface, it can float up under the action of buoyancy. As the water level rises, the floating ball 7 moves up synchronously. When the floating ball 7 moves up, it pushes the driving rod 6, and the valve core 5 is driven to move axially through the driving rod 6.

[0023] The valve core 5 is slidably connected to the guide base 8, and the guide base 8 plays a guiding role.

[0024] Among them, a flow channel 9 is arranged inside the valve body 4, the flow channel 9 of the valve body 4 is connected with the water inlet pipe 2, and the flow channel 9 of the valve body 4 is connected with the faucet 3. When the flow channel 9 is in an open state, the water can flow normally.

[0025] Among them, the valve core 5 slides relative to the guide base 8 during axial movement. When the water level rises to a certain height, the float 7 drives the valve core 5 to block the internal flow channel 9 of the valve body 4 to achieve interception. At this time, the water inside the water inlet pipe 2 cannot enter the faucet 3 through the water-saving valve 1, and the faucet 3 stops flowing and automatically intercepts the flow. When the water level drops, the float 7 moves downward with the water level. While moving downward, the float 7 drives the drive rod 6 and the valve core 5 to move downward synchronously. The valve core 5 is reset and moves back to the guide base 8. At this time, the internal flow channel 9 of the valve body 4 is opened, connecting the water inlet pipe 2 and the faucet 3. The water can enter the faucet 3 through the water-saving valve 1 and flow out normally through the faucet 3. The normal opening and closing of the water flow is achieved by controlling the opening and closing of the faucet 3.

[0026] Among them, when the user leaves the water use place and forgets to close the faucet 3, water continues to flow out and the water level continues to rise. When the water level rises to a certain height, the valve core 5 moves up to block the internal flow channel 9 of the valve body 4, thereby intercepting the flow and preventing the water from continuing to flow out through the faucet 3, eliminating water seepage and leakage, preventing water leakage accidents, and avoiding a large amount of water resource waste, thereby achieving the purpose of saving water and reducing economic losses.

[0027] The water-saving valve 1 has a simple structure, does not require an external power supply when in use, and uses a mechanical structure to achieve water saving, which is low in cost.

[0028] Among them, the driving rod 6 includes a first rod body 11 and a second rod body 12. One end of the first rod body 11 is fixedly connected to the valve core 5, and one end of the second rod body 12 is fixedly connected to the float 7. The first rod body 11 and the second rod body 12 are detachable structures, which is convenient for maintenance and replacement.

[0029] A threaded connection portion 13 is disposed on the first rod body 11 , and a threaded connection groove 14 is disposed inside the second rod body 12 .

[0030] One end of the first rod body 11 is embedded in the second rod body 12 , and the first rod body 11 and the second rod body 12 are threadedly connected.

[0031] Among them, the extension length of the first rod body 11 relative to the second rod body 12 is adjustable, and the adjustment method is to rotate the second rod body 12 and adjust the extension length of the first rod body 11 relative to the second rod body 12 by relying on the threaded connection position, that is, the total length of the driving rod 6 is adjusted. According to the use requirements, the length of the driving rod 6 can be flexibly adjusted, and the position of the float 7 can be adjusted to adjust the intercepted water level, thereby improving the flexibility of the water-saving valve 1 during use.

[0032] Wherein, connectors 10 are provided at both ends of the water-saving valve 1 , and the water-saving valve 1 is fixedly connected to the water inlet pipe 2 and the faucet 3 via the connector 10 .

[0033] Among them, the connector 10 at one end of the water-saving valve 1 is threadedly connected to the water inlet pipe 2. The connection method between the water-saving valve 1 and the water inlet pipe 2 is simple, and the two are detachably connected, which is convenient for assembly and disassembly, and is conducive to maintenance and replacement.

[0034] Among them, the connector 10 at the other end of the water-saving valve 1 is threadedly connected to the faucet 3. The connection between the water-saving valve 1 and the faucet 3 is simple, and the two are detachably connected, which is convenient for assembly and disassembly, and is conducive to maintenance and replacement.

[0035] Working principle: When in use, the water-saving valve 1 is fixedly connected to the water inlet pipe 2 and the faucet 3 through the connector 10. The water-saving valve 1 is installed on the water inlet pipe 2 and placed between the water inlet pipe 2 and the faucet 3 for use. The flow channel 9 of the valve body 4 is connected to the water inlet pipe 2, and the flow channel 9 of the valve body 4 is connected to the faucet 3. During normal use, the flow channel 9 is in an open state, connecting the water inlet pipe 2 and the faucet 3. The water in the water inlet pipe 2 can enter the faucet 3 through the water-saving valve 1 and flow out normally through the faucet 3. When the user leaves the water-using place and forgets to close the faucet 3, the water continues to flow out and the water level continues to rise. When the water level rises to a certain height, the float 7 contacts the water surface, and the float 7 can float under the buoyancy. 4, and the spool 5 is automatically shut off when the water level drops.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
