[0027] As Figures 1 to 3As shown, an anti-overflow structure of a wall-mounted water dispenser includes a wall-mounted water dispenser body 1 provided with a control panel 11, the wall-mounted water dispenser body 1 is provided with a water tank 2, the wall-mounted water dispenser body 1 is provided with a water inlet 1a and a water outlet assembly 3, the water tank 2 is connected with the water outlet assembly 3 through a water delivery pump 4 and a heater 5, the wall-mounted water dispenser body 1 is provided with a water level control pipe 6 communicated with the water tank 2, the upper end of the water level control pipe 6 is connected with an exhaust hole 1b, the water level control pipe 6 is provided with a float ball 61, the water level control pipe 6 is provided with an overflow port 6a and a reed tube 62 connected with the control panel 11, the overflow port 6a is connected with an overflow box 7 arranged in the wall-mounted water dispenser body 1, the overflow box 7 is provided with a float switch valve 8, the water inlet 1a is connected with the water tank 2 through a water inlet electromagnetic valve 12 and the float switch valve 8.

[0028] The water inlet electromagnetic valve 12 is used for controlling the opening and closing of the water inlet pipeline, and the water delivery pump 4 is used for providing water delivery power, and their setting positions can be adjusted on the pipeline as needed.

[0029] The water level control pipe 6 is communicated with the water tank 2 to form a communicating vessel, that is, the water level in the water level control pipe 6 is the same as the water level in the water tank 2, in order to make the water in the communicating vessel flow out smoothly, it must be communicated with the atmosphere, that is, it must be communicated with the exhaust hole 1b. In the embodiment, the water tank 2 adopts a closed design, and the exhaust hole 1b is arranged on the water outlet assembly 3, so that the exhaust hole 1b is more concealed, and the overall appearance of the wall-mounted water dispenser can be improved.

[0030] The float switch valve 8 includes a shell 81, the upper part of the shell 81 is provided with a connecting head 82, the lower part of the shell 81 is provided with a hollow part 81a, and the shell 81 is provided with a float valve core 83.

[0031] The water tank 2 and the water delivery pump 4 are provided with a sterilization pipe 9. The sterilization pipe 9 can sterilize the water passing through it, and the sterilization pipe 9 is a prior art, and various types and models of sterilization pipes available on the market can be used.

[0032] The sterilization pipe 9 is fixed in the wall-mounted water dispenser body 1 through a sterilization pipe support 91. The sterilization pipe support 91 facilitates the fixation of the sterilization pipe 9.

[0033] The reed tube 62 is arranged below the overflow port 6a.

[0034] The water delivery pump 4 is fixed in the wall-mounted water dispenser body 1 through a water delivery pump support 41.

[0035] The water delivery pump support 41 and the overflow box 7 are an integral part.

[0036] The water delivery pump support 41 facilitates the fixing of the water delivery pump 4,

[0037] The wall-mounted water dispenser body 1 is provided below with a concave cavity 1c, and the water inlet 1a extends into the concave cavity 1c. The wall-mounted water dispenser is provided below the water outlet assembly 3 with a water collecting box 31, which blocks the concave cavity 1c, so as to shield the water inlet 1a arranged in the concave cavity 1c, and improve the overall appearance of the wall-mounted water dispenser.

[0038] Working principle:

[0039] When the wall-mounted water dispenser works normally and the water tank 2 is replenished with water, the water inlet electromagnetic valve 12 is opened, water flows into the water tank 2 from the water inlet 1a through the water inlet electromagnetic valve 12 and the float switch valve 8. Since the water level control pipe 6 is communicated with the water tank 2, the water level in the water level control pipe 6 is equal to the water level in the water tank 2, and the float ball 61 in the water level control pipe 6 monitors the water level. When the water level rises to the position of the reed tube 62, the water inlet electromagnetic valve 12 is closed to stop water inflow. Here, the cooperation of the float ball 61 and the reed tube 62 achieves the purpose of automatic water replenishment and also plays a first water overflow protection role. When taking water, the water in the water tank 2 is discharged from the water outlet assembly 3 through the sterilization pipe 9 and the heater 5 (when taking cold water, the heater 5 does not work). When working normally, the overflow box 7 is empty, and the float valve core 83 of the float switch valve 8 is located at the lower limit, and the float switch valve 8 is in an open state.

[0040] In the above anti-overflow structure, once a link fails, such as the float ball 61 being stuck or the reed tube 62 being out of order, there is still a risk of water overflow. At this time, the water level will exceed the set height (i.e. higher than the position of the reed tube 62), and at this time, the water in the water level control pipe 6 will flow into the overflow box 7 from the overflow port 6a. With the rising of the water level in the overflow box 7, the float valve core 83 of the float switch valve 8 rises, thereby closing the float switch valve 8, the water inflow passage is blocked, and water inflow is stopped, thereby achieving the purpose of preventing water overflow, and also playing a second water overflow protection role.

[0041] The above is only the preferred embodiment of the present application, and does not limit the implementation and protection scope of the present application. For those skilled in the art, it should be realized that any equivalent replacement and obvious changes made by applying the contents of the present application specification and drawings should be included in the protection scope of the present application.
