[0028] The water tank 5 is provided with an opening 15 protruding outward, and a clamping ring 16 is provided above the inner wall of the tank body 1. The clamping ring 16 is arranged around the water inlet pipe 4. The water tank 5 is connected to the tank body 1 by installing the opening 15 into the clamping ring 16. After the opening 15 is installed into the clamping ring 16, the opening 15 will be clamped in the clamping ring 16, thereby fixing the water tank 5.

[0029] A convex ring 17 is provided on the inner wall of the clamping ring 16, and an annular groove 18 is provided on the outer wall of the opening 15. After the opening 15 is installed inside the clamping ring 16, the convex ring 17 is located in the annular groove 18, and the convex ring 17 and the annular groove 18 form a clamping structure. The above structure makes it easy to install the water storage tank 5, and the connection structure between the water storage tank 5 and the tank body 1 is stable.

[0030] The water outlet pipe 11 includes a first annular layer 19 and a second annular layer 20, the second annular layer 20 is arranged around the first annular layer 19, a fourth space 21 is arranged inside the first annular layer 19, a fifth space 22 is arranged between the first annular layer 19 and the second annular layer 20, and the floating plug 6 is located at one end of the water outlet pipe 11 and is provided with a protrusion 23 and a third annular layer 24, the third annular layer 24 is arranged around the protrusion 23, and a sixth space 25 is arranged between the third annular layer 24 and the protrusion 23; when the floating plug 6 blocks the water outlet 10, the protrusion 23 is located in the fourth space 21, the first annular layer 19 is located in the sixth space 25, and the third ring is located in the fifth space 22. With the above structure, the floating plug 6 can be more closely matched with the water outlet pipe 11.

[0031] The first annular layer 19, the second annular layer 20 and the tank body 1 are integrally formed, and the integrally formed structure can make the humidification tank more sealed and more stable.

[0032] The water tank 5 is provided with a first convex strip 26, which is arranged around the side edge of the water tank 5, and the side of the first convex strip 26 abuts against the inner wall of the tank body 1; the water tank 5 is provided with a second convex strip 27, which is located above the water tank 5, and the upper surface of the second convex strip 27 abuts against the inner top surface of the tank body 1; both ends of the second convex strip 27 are connected to the first convex strip 26, the first space 7 is located on one side of the second convex strip 27, and the second space 8 is located on the other side of the second convex strip 27. Under the coordinated arrangement of the water tank 5, the first convex strip 26 and the second convex strip 27, the interior of the tank body 1 is divided into a first space 7, a second space 8 and a third space 9, and the first space 7 and the second space 8 are not directly connected, but are connected by being connected to the third space 9 together, so that the gas in the first space 7 can be prevented from directly entering the second space 8. The gas entering from the air inlet 2 first enters the first space 7 , the gas in the first space 7 enters the third space 9 , the gas in the third space 9 enters the second space 8 , and finally the gas flows out from the air outlet 3 .

[0033] A first notch 28 is provided on one side of the first space 7 of the first convex strip 26, and the first space 7 is connected to the third space 9 through the first notch 28; a second notch 29 is provided on one side of the second space 8 of the first convex strip 26, and the second space 8 is connected to the third space 9 through the second notch 29. With the above structure, the connecting point between the first space 7 and the third space 9 and the connecting point between the second space 8 and the third space 9 are both located at the edge of the inside of the tank body 1, which increases the distance between the connecting point between the first space 7 and the third space 9 and the air inlet 2 and increases the distance between the connecting point between the second space 8 and the third space 9 and the air outlet 3, thereby improving the effect of preventing dumping and outflow.

[0034] The first notch 28 and the second notch 29 are both arranged beside the second ridge 27, the connection between the air inlet 2 and the first space 7 is located on the side opposite to the first notch 28, and the connection between the air outlet 3 and the second space 8 is located on the side opposite to the second notch 29. The distance between the connection between the first space 7 and the third space 9 and the air inlet 2 and the distance between the connection between the second space 8 and the third space 9 and the air outlet 3 are maximized, so as to achieve the best anti-dumping and outflow effect.

[0035] The first convex strip 26 is arranged in a circular ring shape, and the first notch 28 is arranged in an arc shape. The arc length of the first notch 28 is not greater than one quarter of the circular ring circumference of the first convex strip 26. The first notch 28 and the second notch 29 have the same shape and size. With the above structure, the humidification tank can have a good anti-dumping and outflow effect.

[0036] The clamping ring 16 is provided with two third notches 30, and the two third notches 30 are arranged in opposite positions. Since the clamping ring 16 is provided with two third notches 30, when the opening 15 is installed on the clamping ring 16, the two sides of the clamping ring 16 will be elastically deformed outward. When the opening 15 is installed on the clamping ring 16, the clamping ring 16 returns to its original shape and plays the role of clamping the opening 15. The installation opening of the sealing cover 12 is located at the top center of the tank body 1, and the second convex strip 27 is located in the middle of the top surface of the tank body 1. The installation opening of the sealing cover 12 is horizontally penetrated by the second convex strip 27. After the opening 15 is installed on the clamping ring 16, the second convex strip 27 will pass through the two third notches 30. The two third notches 30 play the role of preventing the second convex strip 27 from moving horizontally or rotating, so that the water storage tank 5 is installed more stably.

[0037] Sealing strips 31 are provided on the surface where the first ridge 26 contacts the inner wall of the tank body 1 and on the surface where the second ridge 27 contacts the inner wall of the tank body 1. The sealing strips 31 are provided to improve the sealing performance between the first ridge 26 and the inner wall of the tank body 1 and the sealing performance between the second ridge 27 and the inner wall of the tank body 1. On the one hand, the gas in the first space 7 can be prevented from directly entering the second space 8. On the other hand, when the tank body 1 is tilted, the water in the tank body 1 can be prevented from flowing into the first space 7 and the second space 8 from the gap between the first ridge 26 and the inner wall of the tank body 1.

[0038] A first sealing ring 32 and a second sealing ring 33 are provided on the surface where the sealing strip 31 contacts the inner wall of the tank body 1. The first sealing ring 32 and the second sealing ring 33 are both outwardly protruding structures, and a sealing space 34 is provided between the first sealing ring 32 and the second sealing ring 33, so that the sealing strip 31 contacts the inner wall of the tank body 1 more closely, thereby improving the sealing performance.

[0039] The outer side surface of the first convex strip 26 is concave in shape, and the inner side surface of the sealing strip 31 matches the outer side surface of the first convex strip 26 , so that the sealing strip 31 and the first convex strip 26 are more closely combined to improve the sealing performance.

[0040] The first space 7 and the second space 8 have the same shape and size, which can ensure more stable gas transportation.

[0041] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention.
