[0032] It can be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number.

[0033] As shown in Figures 1 to 8 A water level control structure of a water dispenser, comprising a wall-mounted water dispenser body 1, a water tank 2 is arranged on the wall-mounted water dispenser body 1, a water level monitoring pipe 3 is arranged in the wall-mounted water dispenser body 1, the upper end of the water level monitoring pipe 3 is connected with an exhaust hole 1a, the water level of the water level monitoring pipe 3 is the same as the water level of the water tank 2, upper limit position dry reed pipe 3a and lower limit position dry reed pipe 3b are arranged on the water level monitoring pipe 3, the water level monitoring pipe 3 comprises first pipe body 31 and second pipe body 32 which are in communication with each other, first floating ball 31a is arranged in the first pipe body 31, second floating ball 32a is arranged in the second pipe body 32, and separation structure for preventing the second floating ball 32a from entering the first pipe body 31 is arranged between the first pipe body 31 and the second pipe body 32.

[0034] The separation structure is a separation piece 33 arranged between the first pipe body 31 and the second pipe body 32.

[0035] The separation piece 33 is in a cylindrical structure.

[0036] The upper end of the first pipe body 31 is provided with a grid part 31b, and the separation piece 33 is assembled on the grid part 31b.

[0037] The water tank 2 is detachably connected with the wall-mounted water dispenser body 1. Since the water outlet assembly 2 has a small water outlet flow, when water is needed to be quickly added (for example, when water is needed to be added during cooking), the water tank 2 can be detached from the wall-mounted water dispenser body 1 and the water tank 2 is used to quickly pour water through the pouring spout 21.

[0038] The water tank 2 is provided with a water passing opening 2a, the water supply opening 1b of the wall-mounted water dispenser body 1 is connected with the water passing opening 2a of the water tank 2 and the inlet of the water level monitoring pipe 3 through the flow divider 4, the diameter of the water passing opening 2a of the water tank 2 matches the diameter of the inlet of the water level monitoring pipe 3, so that the water levels in the water tank 2 and the water level monitoring pipe 3 are equal.

[0039] Since the water in the water tank 2 and the water level monitoring pipe 3 is input from the flow divider 4 when water is added, the water flow rates of the water in the water tank 2 and the water level monitoring pipe 3 are the same, in order to make the water levels in the water tank 2 and the water level monitoring pipe 3 equal, the ratio of the diameter of the water passing opening 2a of the water tank 2 to the diameter of the inlet of the water level monitoring pipe 3 can be calculated by calculating the ratio of the cross-sectional areas of the water tank 2 and the water level monitoring pipe 3.

[0040] The water passing opening 2a of the water tank 2 is provided with the elastic switch valve 5, and the wall-mounted water dispenser body 1 is provided with the trigger part 11 for opening the elastic switch valve 5. The elastic switch valve 5 is arranged so that when the water tank 2 is detached, the water passing opening 2a is in a closed state, and when the water tank 2 is installed on the wall-mounted water dispenser body 1, the trigger part 11 contacts the elastic switch valve 5, so that the valve core is retracted to open the water passing opening 2a. The elastic switch valve 5 is a prior art, and its specific structure is not described here.

[0041] The water tank 2 is provided with a magnet 61, and the wall-mounted water dispenser body 1 is provided with a magnetic induction switch 62 at a corresponding position. The magnetic induction switch 62 detects whether the water tank 2 is installed in place.

[0042] The upper end of the water tank 2 is provided with the pouring spout 21, and the wall-mounted water dispenser body 1 is provided with the cavity 12 matched with the pouring spout 21. When the water tank 2 is installed on the wall-mounted water dispenser body 1, the pouring spout 21 is located in the cavity 12, so that the structure of the wall-mounted water dispenser is more compact.

[0043] The air vent 1a is arranged at the position of the cavity 12. In this way, the air vent 1a is arranged to be hidden, which can improve the overall appearance of the wall-mounted water dispenser.

[0044] Working principle:

[0045] Because the water level monitoring pipe 3 is in an elongated structure, the cross-sectional area of the water level monitoring pipe 3 is small, and if the water level monitoring pipe 3 is in an integrated structure, due to the surface tension of water and the effect of air pressure, the float ball may not continue to float when it rises to a certain height.

[0046] In the water level control structure, the water level monitoring pipe 3 is in a two-section structure, which ensures that the water level monitoring pipe 3 can work normally and ensures the reliability of water level monitoring.

[0047] The water supply port 1a of the wall-mounted water dispenser is generally connected with an RO machine, and when water is supplied, the water is supplied to the water tank 2 and the water level monitoring pipe 3 at the same time through the shunt valve 4, the diameter of the water passage 2a of the water tank 2 matches the diameter of the inlet of the water level monitoring pipe 3, so that the water levels in the water tank 2 and the water level monitoring pipe 3 are equal, and thus the water level in the water tank 2 can be monitored by monitoring the water level in the water level monitoring pipe 3.

[0048] When the lower limit position reed switch 3b detects the first float ball 31a, it indicates that the water level reaches the lower limit position and needs to be replenished, and as the water level rises, the first float ball 31a rises in the first pipe body 31 until the top of the first pipe body 31, and as the water level continues to rise, the second float ball 32a in the second pipe body 32 rises, and when the upper limit position reed switch 3a detects the second float ball 32a, it indicates that the water level reaches the upper limit position and stops replenishing.

[0049] The above is only a preferred embodiment of the present application, and does not limit the implementation and protection scope of the present application, and those skilled in the art should be able to realize that any equivalent replacement and obvious changes made by using the content of the present application specification and drawings should be included in the protection scope of the present application.
