DETAILED DESCRIPTION

[0038] Embodiment one

[0039] The utility model is described in detail below. Figures 1 to 4 The utility model is described in detail below.

[0040] A water tank for providing constant-temperature cleaning water comprises a box 10, which is provided with cavities and water inlets and outlets communicating with the cavities. The water tank further comprises a heating device 20, the heating end of which is located in the cavities for heating the water in the cavities. The outer side of the box 10 is provided with a heat preservation layer 30 at least in part. The heat preservation layer 30 reduces the rate of decrease of the temperature of the cleaning water, thereby reducing the number of starts of the heating device 20, reducing the power consumption, reducing the use cost of the user, and improving the use experience of the user. Preferably, the material of the heat preservation layer 30 is rubber-plastic material with an aluminum foil layer.

[0041] The box 10 has a first cavity 1011 and a second cavity 1012 arranged in sequence and communicating with each other from bottom to top. The volume of the first cavity 1011 is smaller than that of the second cavity 1012. The heating end of the heating device 20 is located in the first cavity 1011. The water in the first cavity 1011 is heated for a short time. The water outlet is communicated with the first cavity 1011, thereby shortening the water outlet time of the water outlet. At the same time, because the density of hot water is smaller than that of cold water, during the heating process of the cleaning water, the hot water at the bottom and the cold water at the top automatically flow to form a water circulation, so that the temperature of the cleaning water at each part of the water tank gradually rises, and the heating efficiency is improved. In addition, the design of the water tank being wide at the top and narrow at the bottom reduces the occupation of the internal space of the closestool. The saved space can be used for installing other components such as the booster pump 70.

[0042] In the embodiment, the water tank further comprises a protective cover 40, which is sleeved on the outside of the box 10. The heat preservation layer 30 is arranged between the protective cover 40 and the box 10. The protective cover 40 effectively protects the heat preservation layer 30 from physical damage such as collision and scratching by external objects, prolongs the service life of the heat preservation layer 30, and is convenient to clean. The dust and dirt on the surface of the protective cover 40 are cleaned regularly, so that the water tank is kept clean and hygienic.

[0043] In this embodiment, as shown in Figure 4 The water tank is also provided with a sterilization device 50, which is a UVC sterilization module. The spectral band of the UVC sterilization module is 260-280 nm, and the radiation angle of the UVC sterilization module is at least 100 degrees. Further, the UVC sterilization module is a deep ultraviolet LED. When the spectral band is 260-280 nm, the penetration in water is good, and the deep ultraviolet LED under this spectral band has little attenuation in water, which means that more water can be treated in the same device volume or space, so that the sterilization device 50 has a significant inactivation effect on microorganisms and the sterilization efficiency is significantly improved. Preferably, the radiation angle is 120 degrees, the radiation area is large, and the sterilization efficiency can reach 99.9%.

[0044] In this embodiment, the sterilization device 50 is located at the top of the cavity, and the light emitting end of the sterilization device 50 irradiates from the top of the cavity to the bottom of the cavity, which can cover the entire space inside the water tank. Compared with the irradiation from the bottom or the side wall of the water tank, the top irradiation can avoid the situation that the light is blocked or insufficiently reflected, so as to ensure that the microorganisms, bacteria, viruses and the like in the water can be effectively irradiated, and the sterilization and disinfection are realized in all directions.

[0045] The top of the tank body 10 is provided with a water overflow port 1021 communicating with the cavity. The excess clean water in the other functional waterways flows back to the water tank through the water overflow port 1021, so as to ensure the safety of the water and save water. The tank body 10 is also provided with a drain port which can be opened and closed and communicates with the cavity, so as to facilitate the periodic discharge of impurities and dirt accumulated at the bottom of the water tank and keep the water tank clean.

[0046] In this embodiment, the tank body 10 includes a body 101 and a cover 102. The space surrounded by the body 101 and the cover 102 constitutes a cavity. The body 101 is composed of a first cavity 1011 and a second cavity 1012. The water overflow port 1021 is arranged on the cover 102, and the sterilization device 50 is arranged on the side of the cover 102 facing the cavity.

[0047] In this embodiment, a water inlet valve 60 is arranged at the water inlet port, and a booster pump 70 is arranged at the water outlet port. The space saved at the bottom of the tank body 10 can be used to install the booster pump 70, as shown in Figure 4 A liquid level switch 80 is arranged in the tank body 10. The liquid level switch 80 is electrically connected to a control device 90 arranged on the cover 102. The control device 90 controls the opening and closing of the water inlet valve 60 and the booster pump 70 based on the liquid level switch 80. The liquid level switch 80 is a double-float switch, which is used to monitor the highest and lowest liquid levels in the water tank. In other embodiments, water level sensors are arranged at the highest and lowest water levels in the water tank, respectively.

[0048] The liquid level switch 80 monitors the water level at the highest level, and the control device 90 closes the water inlet valve 60 to avoid the water tank from overflowing due to excessive water inflow. When the liquid level switch 80 monitors the water level at the lowest level, the control device 90 closes the booster pump 70 to avoid damage caused by the idling of the booster pump 70. Preferably, the water inlet valve 60 is a normally closed electromagnetic valve; and the booster pump 70 is a vane type variable frequency brushless DC booster water pump, so that the flow rate at the nozzle can reach 1L / min-2L / min, and a high-pressure and high-flow water column can be output, thereby enabling the nozzle to have a deep enema function, and the depth of the deep enema function can reach 5cm-10cm.

[0049] In this embodiment, the box body 10 is provided with a temperature sensor 100 and an over-temperature protector 110, and the temperature sensor 100 is electrically connected to the over-temperature protector 110, and the over-temperature protector 110 is electrically connected to the control device 90. Specifically, when the temperature sensor 100 monitors that the water temperature exceeds the preset maximum temperature, the over-temperature protector 110 closes the heating device 20 through the control device 90. When the user cleans, the water temperature in the water tank is 40 degrees, and when the temperature sensor 100 detects that the water temperature drops to 35 degrees, the control device 90 starts the heating device 20 to heat the water in the water tank; when the temperature sensor 100 detects that the water temperature exceeds 42.5 degrees, the over-temperature protector 110 closes the heating device 20 through the control device 90 based on the water temperature monitored by the temperature sensor 100, to prevent the water temperature in the water tank from being too high to cause harm to the human body.

[0050] In this embodiment, as shown in Figure 5 , the booster pump 70, the heating device 20, the temperature sensor 100, the over-temperature protector 110, and the water inlet valve 60 are all installed on the box body 10, and the bottom of the box body 10 is provided with a drain port for facilitating the discharge of cleaning water when the water tank is cleaned.
