By means of this structure, on one hand, the airflow flowing to the backflow opening 203 from the air supply channel 601 enters the washing cavity 201 to take away the water vapor on the inner wall of the washing cavity 201 and the outer surface of the part to be washed, and on the other hand, the airflow enters the washing module 3 at the same time to dry the water pump 31, the inner wall of a pipeline and the like, thereby avoiding the hygiene risk of bacteria breeding caused by long-term prolonged dampness of the water pump 31 and the pipeline, and being conducive to more durable use.
(39) As shown in FIG. 6 and FIG. 8, besides the features provided by the above embodiment, in this embodiment, it is further specified that a flow guide portion 214 is formed at the bottom of the inner container assembly 2; the flow guide portion 214 is provided with a first liquid passing cavity which communicates with the washing cavity 201 through the backflow opening 203; a first liquid passing opening and a second liquid passing opening which communicate with the first liquid passing cavity are formed in two sides of the flow guide portion 214, respectively; the first liquid passing opening communicates with the water pump 31; and the second liquid passing opening communicates with the output end of the air supply channel 601, and the horizontal height of the second liquid passing opening is greater than that of the first liquid passing opening. By means of this structure, because the horizontal height of the second liquid passing opening is greater than that of the first liquid passing opening, after the cleaning water in the washing cavity 201 enters the first liquid passing cavity through the backflow opening 203, the cleaning water will preferentially enter the water pump 31 or the wastewater tank 33 from the first liquid passing opening at the lower position, and therefore the possibility of the cleaning water entering the air supply channel 601 can be reduced.

By means of this structure, the liquid in the water collecting tank 602 can be conveniently drained through the drain outlet in time, which avoids that too much cleaning water collected by the water collecting tank 602 overflows and flows to the air passing port 6012, and is conducive to reducing the size of the water collecting tank 602, thereby making the structure of the air supply module 6 more compact. Specifically, the water outlet 603 can be in communication with the water pump 31 through the pipeline for recycling again, or in communication with the wastewater tank 33 through the pipeline for collecting in a centralized mode, or directly in communication with the drain outlet of the host 1 for draining to the outside.

By means of this structure, on one hand, the liquid in the water collecting tank 602 can be conveniently drained in time by the drain pipe 61213, and on the other hand, the drain pipe 61213 passes through the second mounting cavity 6011 and the limiting hole 605 to extend to the outside, which reduces the exposure of the drain pipe 61213 and makes the structure of the air duct shell 61 more compact and simpler; and moreover, the drain pipe 61213 and the limiting hole 605 can be matched to realize a limiting effect, so that the second shell 612 can be more easily located on the first shell 611, which makes the mounting more stable.
(46) As shown in FIG. 8, FIG. 10 and FIG. 11, besides the features provided by the above embodiment, in this embodiment, it is further specified that the air supply module 6 further includes the heating assembly 63 which is arranged in the second mounting cavity 6011 and is used for heating air entering the air supply channel 601.
