It can be understood that, when the steam generating device 2 is in operation, under the heating of the heating assembly 23, the water in the water tank assembly 21 can be evaporated to generate steam, and as the volume of the generated steam increases, when the pressure of the steam in the water tank assembly 21 is greater than the pressure at the steam outlet 2111, the high-pressure steam in the water tank assembly 21 can sequentially pass through the steam outlet 2111, the communicating pipe 26 and the nozzle 13, and enter the air treatment device 1 through the open end of the nozzle 13, and then be mixed with the air flow in the air treatment device 1, and finally be delivered to the indoor space through the air treatment device 1.

According to the utility model discloses steam generation device 2, steam generation device 2 includes spray tube 13, spray tube 13 is installed in air treatment device 1, spray tube 13's one end and the pipeline intercommunication that supplies water vapour to air treatment device 1, spray tube 13's the other end opens, water vapour can carry to air treatment device 1's inside through spray tube 13 from this to mix with the inside dry air current of air treatment device 1, make air treatment device 1 have the effect of humidification, thereby can promote the travelling comfort that the user used.

In addition, the cost can be reduced while the connection strength of the nozzle 13 and the communicating pipe 26 is ensured.

According to some embodiments of the present invention, the nozzle 13 is connected to the communicating tube 26 by a threaded connection. The threaded connector has the advantages of simple structure and easy assembly, and the spray pipe 13 and the communicating pipe 26 can be tightly connected through the threaded connector. In addition, the cost can be reduced while the connection strength of the nozzle 13 and the communicating pipe 26 is ensured. Alternatively, the threaded connection may be a screw, bolt or stud.

According to some embodiments of the present invention, as shown in fig. 5 and 6, the inside of the nozzle 13 is provided with a filter 133. The filtering member 133 has a filtering effect on the particles with larger diameter, and can prevent large particles from entering the spraying pipe 13, so that the flowing smoothness of the steam can be improved, and the loss of the steam energy can be reduced. For example, in some examples of the invention, the filter element 133 is located at the fourth end 132 of the spout 13.

Impurities carried in the water are easily scaled in the water tank assembly 21, and the thicker the scale layer is, the more difficult the scale layer is to be removed. In addition, the water mist carrying impurities is inevitably wrapped up when the steam in the water tank assembly 21 is discharged, and when the impurity content in the water is too high, the sprayed water mist also influences the health of people. Therefore, the water tank assembly 21 needs to be cleaned periodically, and by providing the water outlet 2112, the cleaned sewage can be discharged out of the water tank assembly 21 through the water outlet 2112, so that the cleanliness of the water tank assembly 21 can be improved.

In some embodiments of the present invention, the water tank assembly 21 includes a water replenishing tank 212 and a working water tank 211, one end of the water replenishing tank 212 is communicated with the water source, and the other end of the water replenishing tank 212 is communicated with the working water tank 211 through a pipeline. The water replenishing tank 212 can be used for timely conveying the water for replenishing to the working water tank 211, and the problem that the working water tank 211 cannot replenish water due to temporary water cut can be solved by setting the water replenishing tank 212, so that when the water cut of a short time occurs, the water replenishing tank 212 can still timely replenish water to the working water tank 211, the working water tank 211 can still continue to work at the moment, and the reliability and the safety of the work of the steam generating device 2 can be improved.

For example, in some examples of the present invention, the number of the water replenishing tanks 212 is one, the number of the working tanks 211 is plural, and the plural working tanks 211 are respectively communicated with the water replenishing tanks 212 through pipes.

For another example, in some examples of the present invention, the water replenishing tanks 212 are provided in a plurality, the working tanks 211 are provided in a plurality, and the water replenishing tanks 212 are matched with the working tanks 211 in a one-to-one correspondence manner.

Further, as shown in fig. 7, a check valve 24 is provided on a pipe between the refill water tank 212 and the working water tank 211 so that fluid can flow only from the refill water tank 212 to the working water tank 211. Therefore, water in the working water tank 211 can be prevented from flowing back to the water supplementing water tank 212 under the action of high-pressure steam, and meanwhile, steam in the working water tank 211 can be prevented from flowing back to the water supplementing water tank 212, so that the flowing direction unicity of the steam in the working water tank 211 can be ensured. It should be noted that the check valve 24 herein enables fluid to flow only from the refill water tank 212 to the working water tank 211, while preventing steam in the working water tank 211 from flowing back into the refill water tank 212.

In order to ensure the safety of the operation of the steam generator 2, the water supply tank 212 may supply the working water tank 211 with the supply water in a case where no steam is generated in the working water tank 211. Alternatively, when the air pressure in the working water tank 211 is the same as the air pressure in the water replenishment water tank 212, the water replenishment water tank 212 supplies the replenishment water to the working water tank 211.
