The float valve 870 is arranged in the water supply tank 828, and the float valve 870 is used to control the on and off of the water inlet 822.

As shown in FIG. 4, according to another specific embodiment of the present application, the water tank assembly 820 may include: a working water tank 827 and a supplemental water tank 828. The working water tank 827 may have a heating cavity 826, the steam outlet 821 may be provided in the working water tank 827, and the make-up water tank 828 may be connected to the working water tank 827 through a connecting pipe 829, so that the structure of the working water tank 827 and the make-up water tank 828 can form a communicating mechanism. The nozzle 822 is provided in the water supply tank 828. The upper end of the working water tank 827 is connected to the upper end of the supplementary water tank 828. This arrangement can ensure that the pressures in the working water tank 827 and the supplementary water tank 828 are equal, and can prevent excessive pressure in the working water tank 827 from returning the water pressure to the supplementary water tank 828.

In some embodiments of the present application, as shown in FIG. 16, a one-way valve may be provided on the U-shaped pipe. The one-way valve can enable fluid to flow only from the makeup water tank 828 to the working water tank 827. This arrangement can avoid the working water tank. The fluid in 827 flows to the make-up water tank 828, so that enough fluid can be stored in the working water tank 827.

In some embodiments of the present application, the working water tank 827 may have an air pressure adjusting port 8293, and the air pressure adjusting port 8293 may communicate with the heating chamber 826. It should be noted that when the working water tank 827 needs to be filled with water, the air pressure adjustment port 8293 is opened, and the gas pressure in the heating chamber 826 is rapidly reduced, so that the pressure in the heating chamber 826 can be quickly approached to atmospheric pressure, thereby ensuring that the water supply tank 828 The water quickly flows into the working water tank 827, and the work of refilling the working water tank 827 can be completed.

In some embodiments of the present application, a steam valve 8294 may be provided at the air pressure regulating port 8293, wherein the steam valve 8294 can be connected to the controller, and the steam valve 8294 can better control the opening and closing of the air pressure regulating port 8293. When it is necessary to supply water to the working water tank 827, the controller controls the steam valve 8294 to open so that the pressure in the heating chamber 826 quickly approaches the atmospheric pressure, thereby further ensuring that the water in the water supply tank 828 quickly flows into the working water tank 827. When there is no need to add water to the working water tank 827, the controller controls the steam valve 8294 to close.

It should be noted that when the steam generating device 800 needs to be filled with water into the working water tank 827 for the first time or after working for a period of time, the water filling tank 828 can fill the working water tank 827 through the connecting pipe 829. When a U-shaped pipe is connected between the make-up water tank 828 and the working water tank 827, the principle of the communicating device can be used to make the water in the make-up water tank 828 supplement the working water tank 827. When the water level in the make-up water tank 828 drops, and the water level detector 840 When it is detected that the water supply tank 828 needs to be refilled, the normally closed solenoid valve 850 opens to replenish water into the water supply tank 828. Since the water supply tank 828 and the working water tank 827 form a connector, the liquid levels in the two tanks are level. When the water level in the makeup water tank 828 reaches a certain height, the water level detector 840 sends an electrical signal to control the water inlet normally closed solenoid valve 850 to close, thereby eliminating the need to fill the water tank 828 with water.

When the water in the make-up water tank 828 and the working water tank 827 is sufficient and water vapor needs to be generated, the heating component 830 can be activated to make the heating component 830 heat the water in the working water tank 827 to generate water vapor. The heating component 830 is in the heating process , The atmospheric pressure in the working water tank 827 gradually increases. Because the connecting pipe 829 is provided with a one-way valve, the fluid cannot flow from the working water tank 827 to the makeup water tank 828. At this time, under the action of the air pressure in the working water tank 827, the makeup water tank 828 The working water tank 827 is no longer replenishing water, that is, the pressure generated by the height difference between the liquid column heights in the replenishing water tank 828 and the working water tank 827 is equal to the pressure in the working water tank 827. At this time, the replenishing water tank 828 does not replenish the working water tank 827.

After the heating element 830 is heated for a period of time and the water around the heating element 830 is insufficient, a small amount of water vapor is generated or no water vapor is generated in the working water tank 827. If water vapor needs to be continuously generated at this time, water needs to be added to the working water tank 827 , That is, it is necessary to wait for the air pressure in the working water tank 827 to be equal to the air pressure in the make-up water tank 828 before the make-up water tank 828 can supply water to the working water tank 827. In order to balance the air pressure in the working water tank 827 and the make-up water tank 828, the following two methods can be used: 1) Since the heating element 830 is not heating, the temperature in the working water tank 827 gradually drops, and the remaining water vapor in the working water tank 827 gradually condenses As a result, the air pressure in the working water tank 827 gradually decreases. When the air pressure in the working water tank 827 drops to a certain level, the water in the make-up water tank 828 can flow into the working water tank 827 by using the principle of the communicating device; 2) In order to be able to balance quickly The pressure in the working water tank 827 and the makeup water tank 828 can be provided with an air pressure regulating port 8293 on the working water tank 827, and a steam valve 8294 can be provided at the air pressure regulating port 8293. When the pressure in the working water tank 827 and the makeup water tank 828 needs to be balanced, open The steam valve 8294 quickly restores the pressure in the working water tank 827 to atmospheric pressure, which can then be balanced with the pressure in the makeup water tank 828.
