In this embodiment, the water tank 1 is provided with an overflow structure, which is specifically an overflow pipe 2, the top end of the overflow pipe 2 is provided with an overflow port 21 located in the water storage cavity 15, the bottom end of the overflow pipe 2 is provided with a water outlet 22, and the water outlet 22 leads to the outside of the water tank 1. In particular, the drain opening 22 is located in the bottom wall of the tank 1, but is not limited thereto, and in other embodiments, the drain opening is located in the bottom of the side wall of the tank. In other embodiments, the overflow structure is an overflow port disposed on a sidewall of the tank.

In this embodiment, the water tank 1 is further provided with a water inlet pipe 3, one end of the water inlet pipe 3 is provided with a second water outlet 31 located in the water storage cavity 15, and a water outlet surface of the second water outlet 31 forms a water outlet surface of the water inlet structure; the other end of the water inlet pipe 3 is provided with a second water inlet 32, and the second water inlet 32 is communicated with the outside of the water tank 1. In particular, the second water inlet 32 is located on the side wall of the water tank 1, as shown in fig. 2, but is not limited thereto. In other embodiments, the second water inlet is located in the bottom wall or the top wall of the water tank. The second water outlet 31 is higher than the overflow port 21.

In this embodiment, the overflow pipe 2 is close to the inner side surface of the water tank 1, so that the overflow pipe 2 can give way to the larger space inside the water tank 1, thereby facilitating the installation of other parts. Specifically, the overflow pipe 2 is adjacent to the inner side surface of the upper shell described below. The overflow pipe 2 is far away from the water outlet 31 of the water inlet pipe 3, so that the fluctuation generated by the water surface near the water inlet pipe 3 when the water inlet pipe 3 enters water can not cause water to flow away from the overflow pipe 2, thereby reducing the water loss.

In this embodiment, the water tank 1 includes a bottom plate 12 and an upper shell 11 with an opening at the bottom end, the bottom plate 12 is connected to the opening at the bottom end of the upper shell 11 in a sealing manner, and the bottom plate 12 and the upper shell 11 enclose the water storage cavity 15, and specifically, the periphery of the bottom plate 12 is fixed to the upper shell 11 through ultrasonic welding. The heating cavity 13 and the water outlet cavity 16 are located on the upper shell 11, the water pumping pipe 5 is arranged on the upper shell 11, and specifically, the water pumping pipe 5 and the upper shell 11 are integrally formed by injection molding, but not limited to this. The end cover 4 is covered on the upper shell 11, the overflow pipe 2 and the water inlet pipe 3 are vertically arranged on the bottom plate 12, and the overflow pipe 2, the water inlet pipe 3 and the bottom plate 12 are integrally formed by injection molding, but the invention is not limited to this.

When the heating device is used, the other end of the water passing channel 41 of the end cover 4 is communicated with the water inlet end of the water pump.

When water is fed, the water enters from the second water inlet 32, flows upwards along the inner channel of the water inlet pipe 3, and finally flows out from the second water outlet 31 of the water inlet pipe 3 and falls into the water storage cavity 15, as shown in fig. 6. During the water inlet process, the air in the water storage cavity 15 is gradually squeezed and discharged from the overflow pipe 2. When the means for controlling the inflow of water (which may include, for example, a water level detector disposed in the tank, a solenoid valve disposed at the second water inlet 32, and a controller for coordinating the operation of the water level detector and the solenoid valve, etc.) fails, and the second water inlet 32 continues to supply water so that the water in the water storage chamber 15 exceeds the highest water level line, the excess water will enter from the overflow port 21 at the top end of the overflow pipe 2 and flow along the inner channel of the overflow pipe 2 to the water outlet 22, as shown in fig. 7, and finally fall into the toilet tank.

Because the second water outlet 31 is higher than the overflow port 21, the second water outlet 31 is not submerged in water, but is located in the air layer above the overflow port 21, so that when negative pressure occurs in the water supply pipeline connected with the second water inlet 32, water in the water tank 1 cannot flow back, thereby avoiding water source pollution. The overflow pipe 2 can exhaust air and play an overflow role, and water can be directly discharged into the toilet water tank during overflow without being connected with other pipelines, so that the water tank disclosed by the invention is simpler and more attractive in appearance and more convenient to assemble.

When water is pumped, water in the water storage cavity 15 flows into the heating cavity 13 through the water pumping pipe 5 under the action of the water pump, flows along the heating flow channel 131 in the winding shape and is rapidly heated by the ceramic heating plate 7, and finally passes through the water outlet cavity 16, the water passing channel 41 of the end cover and the water pump in sequence as shown in fig. 9 to be output.

Because the water tank 1 is provided with the heating cavity 13, the water tank of the invention can integrate the heating devices in the prior art, thereby not only reducing the parts and assembly steps of the heating devices and saving the cost, but also leading the overall structure of the sanitary cleaning device applying the water tank to be simpler and reducing the occupied space.

The heating path 131 in the serpentine shape increases the heating path of water in the heating chamber 13, so that the water is uniformly and fully heated in the heating chamber 13, and the ceramic heating plate 7 is completely immersed in the water, thereby improving the heating efficiency of the ceramic heating plate. The heating flow path 131 surrounds the first heating surface 71 and the second heating surface 71 of the ceramic heating sheet 7, so that the cross-sectional area of the heating flow path 131 is larger, and the heating flow path is less likely to be clogged with scale even after long-term use.
