DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 The technical solution of the utility model is further illustrated by specific implementation methods.

[0023] The drawings are only used for illustrative purposes and should not be construed as limitations on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, which can be said to be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] A water level control valve, used to control the highest water level of a pure water cup, comprises a water tank 1, a float 4 and a valve body 2; a communication port 11 is provided at the bottom of the water tank 1; the water tank 1 is provided with a high limit water level C and a low limit water level D; the valve body 2 comprises a valve seat 21, a sliding tube 22 and a valve plug 23;

[0026] The valve seat 21 includes a diverter seat 211, a water inlet pipe 212 and a water outlet pipe 213; the communication port 11 is used to communicate with the bottom of the pure water cup; the water inlet pipe 212 is used to communicate with an external water source; the water outlet pipe 213 is used to communicate with the water purifier and transport water;

[0027] The diverter seat 211 is installed on one side of the valve seat 21. The diverter seat 211 is provided with a diverter water inlet hole A and a diverter water outlet hole B. The diverter water inlet hole A is connected to the water inlet pipe 212, and the diverter water outlet hole B is connected to the water outlet pipe 213. The outer side mask of the diverter seat 211 is provided with a sliding tube 22. The sliding tube 22 and the diverter seat 211 constitute a valve cavity. The sealing end of the sliding tube 22 penetrates into the water tank 1. The valve plug 23 is slidably arranged in the sliding tube 22. The body of the valve plug 23 is made of a material that can be attracted by magnets; the valve plug 23 moves linearly along the sliding tube 22, and a sealing plug is installed at the end of the valve plug 23 facing the diverter seat 211; a spring 24 is also installed in the sliding tube 22, one end of the spring 24 is pressed against the sealing end of the sliding tube 22, and the other end of the spring 24 is pressed against the end of the valve plug 23 away from the sealing plug, so that the sealing plug is aligned and used to close the diverter water inlet hole A, and the diverter water outlet hole B is in a normally open state;

[0028] A sliding tube accommodating position 40 is provided at the bottom of the float 4, and a magnetic block 241 is provided inside the float 4, and the magnetic block 241 is arranged corresponding to the sliding tube accommodating position 40; the magnetic block 241 is used to attract the valve plug 23, so that the valve plug 23 compresses the spring 24, so that the sealing plug moves toward the sealing end of the sliding tube 22, and separates the sealing plug from the diversion water inlet hole A, and makes the water inlet pipe 212 and the water outlet pipe 213 conductive.

[0029] like Figure 1-4 As shown, the water level control valve of the utility model is used to control the highest water level of the pure water cup. The pure water cup is connected to the pure water output end of the water purifier. The water tank 1 in the water level control valve is provided with a high limit water level C and a low limit water level D.

[0030] The water level control valve of the utility model uses tap water as the water source. The tap water enters the valve body 2 through the water inlet pipe 212, and then enters the water purifier through the water outlet pipe 213. The tap water is filtered by the water purifier to form pure water, and the pure water is transported to the pure water cup through the pure water output end of the water purifier. As the pure water input into the pure water cup increases, the water level in the pure water cup rises. At the same time, the water level of the water tank 1 connected to the bottom of the pure water cup also rises synchronously, and the float 4 rises accordingly.

[0031] When the water level in the water tank 1 reaches the upper limit water level C, the float 4 rises and moves the magnetic block 241 away from the sealing end of the sliding tube 22. The spring 24 stretches and resets, causing the valve plug 23 to slide along the sliding tube 22 toward the diverter seat 211, thereby causing the sealing plug installed at the end of the valve plug 23 to close the diverter water inlet hole A, thereby disconnecting the water inlet pipe 212 and the water outlet pipe 213, and then shutting off the tap water input into the water purifier, causing the water purifier to stop making water; and then controlling the water level in the pure water cup not to exceed the height corresponding to the upper limit water level C.

[0032] On the contrary, when the water level in the water tank 1 drops and is lower than the lower limit water level D, the magnet 241 that follows the float 4 to descend approaches the sealing end of the sliding tube 22. Under the action of the magnetic attraction of the magnet 241, the valve plug 23 slides along the sliding tube 22 toward the magnet 241. The valve plug 23 compresses the spring 24 and moves the sealing plug toward the sealing end of the sliding tube 22, thereby separating the sealing plug from the diversion water inlet hole A, and then connecting the water inlet pipe 212 and the water outlet pipe 213. The tap water enters the valve body 2 through the water inlet pipe 212, and then enters the water purifier through the water outlet pipe 213, so that the water purifier starts to filter pure water again and fills the pure water cup with pure water again.

[0033] In the above process, the water level control valve can control the on-off of the water source input into the water purifier by using the water pressure of the tap water, so that the pure water cup can always maintain sustainable pure water, and the opening and closing of the water level control valve does not require the use of power.

[0034] Furthermore, a rotating shaft 42 is installed on the top of the side of the float 4 facing the valve body 2;

[0035] The rotating shaft 42 is rotatably mounted on the side wall of the water tank 1 . The rotating shaft 42 is located above the valve body 2 . The rotating shaft 42 extends in a direction perpendicular to the extending direction of the sliding tube 22 .

[0036] like Figure 2 and Figure 4 As shown, the trajectory of the up and down movement of the float 4 can be limited by the rotating shaft 42. When the float 4 is at a low position, it can ensure that the sliding tube 22 is accommodated in the sliding tube accommodating position 40, thereby ensuring the opening and closing effectiveness of the water level control valve during operation.

[0037] Furthermore, a water tank cover 3 is installed on the top of the water tank 1;

[0038] A breathable cover 32 is installed on the top of the pure water cup; a vent hole 31 is opened on the water tank cover 3;

[0039] The vent hole 31 passes through the water tank cover 3 and communicates with the top of the inner cavity of the water tank 1 .

[0040] like Figure 1As shown, the water tank cover 3 is provided with a vent hole 31, which can prevent the inner cavity of the water tank 1 from forming an air chamber, so as to avoid the situation where the water level in the water tank 1 cannot rise and fall synchronously with the water level in the pure water cup.

[0041] Preferably, the top surface of the water tank cover 3 is arranged below the top surface of the pure water cup.

[0042] like Figure 1 and 2 As shown, this can avoid the phenomenon that the pure water cup overflows due to the high limit water level C being too high.

[0043] Preferably, the sliding tube 22 is a transparent body.

[0044] Setting the sliding tube 22 as a transparent body can improve the convenience of observing and checking whether the operating states of the valve plug 23 and the spring 24 in the sliding tube 22 are abnormal.

[0045] In summary, if Figure 1-4 In the embodiment of the utility model shown, the water level control valve can control the on-off of the water source input into the water purifier by using the water pressure of the tap water, so that the pure water cup can always keep pure water that can be used sustainably without using power.

[0046] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
