[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The purpose of the utility model is to provide a double-layer sealing structure of a humidifier water tank to solve the problems existing in the prior art.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] Example 1:

[0022] This embodiment provides a double-layer sealing structure for a humidifier water tank, such as Figure 1 and 2As shown, it includes a water tank 1, a machine base 8 is provided below the water tank 1, the machine base 8 and the water tank 1 are connected through the water tank bottom 2, a water inlet hole is provided on the water tank bottom 2, a double-layer sealing component is provided in the water inlet hole, and a float 7 is connected to the bottom of the double-layer sealing component.

[0024] As an embodiment, the diameter of the large sealing port is larger than the diameter of the small sealing port.

[0025] As an embodiment, the double-layer sealing assembly includes a top rod 6, a large water sealing valve 3 is provided on the top of the top rod 6, the large water sealing valve 3 cooperates with the large sealing port, and a small water sealing valve 4 is provided below the large water sealing valve 3, the small water sealing valve 4 cooperates with the small sealing port.

[0026] As an embodiment, a spring 5 is provided between the top rod 6 and the water tank bottom 2 .

[0027] The utility model provides a double-layer sealing structure for the humidifier water tank, and its working principle is: please refer to Figure 1 and 2 When the water tank is full of water, the float 7 sinks under the action of its own gravity, pushing open the push rod 6 and the large and small water-sealing valves 3 and 4, and the water inside the water tank 1 flows into the machine base 8. When an appropriate amount of water flows into the machine base 8 to float the float 7 to a horizontal state, the large and small water-sealing valves 3 and 4 are respectively pressed against the large and small sealing ports of the water tank bottom 2 by the downward force of the spring 5, forming a sealed state; by adopting a double-valve structure, double-layer insurance is achieved, making it more difficult for the water in the water tank to leak into the machine base, effectively solving the water tank leakage problem. Compared with the single-valve water-sealing structure currently on the market, this double-valve structure has a more reliable water-sealing effect.
