[0023] Specifically: As Figures 1-4 shown, a water tank housing with an overflow structure, a water storage tank 1, and a tank cover 2 is provided at the top of the water storage tank 1; a sealing mechanism 3 for improving the sealing effect of the overflow pipe and preventing water from deteriorating is provided at the top of the tank cover 2; wherein, the sealing mechanism 3 includes an overflow port 301 opened at the top of the tank cover 2, an overflow pipe body 302 is arranged on the inner wall of the overflow port 301, a drainage groove 308 is opened on the inner wall of the overflow pipe body 302, and an installation component 312 is arranged at one end of the overflow pipe body 302.
[0024] As Figure 2 andFigure 3 As shown in the figure, at the other end of the inner wall of the overflow pipe main body 302, there is an installation groove 303. The inner wall of the installation groove 303 is slidably connected with an installation rod 304. The top end of the installation rod 304 is fixedly connected with a foam plastic 305, and the bottom end of the installation rod 304 is fixedly connected with a ball plug 306. At the other end of the overflow pipe main body 302, there is a drain port 307 which is engaged with the ball plug 306. At the other end of the inner wall of the overflow pipe main body 302, there are several uniformly distributed water guide grooves 309. The top end of the water guide groove 309 is communicated with the drainage groove 308, and the bottom end of the water guide groove 309 is respectively communicated with the installation groove 303 and the drain port 307. The outer wall of the ball plug 306 is fixedly connected with a sealing ring 311. At the top end of the foam plastic 305, there is a plastic spring 310. The overflow port 301 discharges water flow into the overflow pipe main body 302. Through the cooperation of the drainage groove 308 and the water guide groove 309, the water flow is first conveyed into the installation groove 303, causing the foam plastic 305 to float and drive the ball plug 306 at one end of the installation rod 304 to move upward. The water guide groove 309 discharges the water flow from the drain port 307. After the water flow is drained, through the elasticity of the plastic spring 310 and the inertia of the ball plug 306 itself, the sealing ring 311 is driven to seal the drain port 307 and the water guide groove 309, which can improve the sealing effect of the overflow pipe and prevent external air from entering the water storage tank 1.
[0025] As Figure 4 As shown in the figure, the installation component 312 includes a clamping plate 3121 fixedly connected to one end of the overflow pipe main body 302. The clamping plate 3121 is clamped to the inner wall of the overflow port 301. Between one end of the overflow pipe main body 302 and the overflow port 301, there is a first sealing gasket 3122.

At one end of the fixed sleeve 3123, there is a second sealing gasket 3124. One end of the overflow pipe main body 302 is inserted into the overflow port 301 through the clamping plate 3121, and the fixed sleeve 3123 is rotated and threadedly connected with the box cover 2 to fix the overflow pipe main body 302. The first sealing gasket 3122 and the second sealing gasket 3124 improve the sealing performance of the overflow pipe main body 302, enabling the quick installation of the overflow pipe and improving the sealing performance of the device.
[0026] When the utility model is in use, the water storage tank 1 discharges water flow through the overflow port 301 at the top of the tank cover 2 into the drainage groove 308 on the inner wall of the overflow pipe main body 302. The drainage groove 308 cooperates with the water guide groove 309 to first convey the water flow into the installation groove 303, causing the foam plastic 305 to float. As the water flow increases, it drives the foam plastic 305 at one end of the installation rod 304 to squeeze and move upward against the plastic spring 310. The water guide groove 309 discharges the water flow from the drainage port 307. After the water flow is drained, the elasticity of the plastic spring 310 and the inertia of the ball plug 306 drive the sealing ring 311 to seal the drainage port 307 and the water guide groove 309. One end of the overflow pipe main body 302 is inserted into the overflow port 301 through the clamping plate 3121, and the fixing sleeve 3123 is rotated and threadedly connected to the tank cover 2 to fix the overflow pipe main body 302.
