With the continuous development of the technical field of cleaning robots, the cleaning robots have entered many common families to clean the ground, and the housework burden of people is effectively reduced. However, the demands of consumers on household sanitation and hygiene are higher, and the demands on the cleaning capability and the cleaning quality of the cleaning appliances are high.

The floor mopping function of the floor sweeping robot in the market is mainly realized by the relative mechanical movement of the mop and the ground, but when some floor stains which are difficult to remove are cleaned, the cleaning effect is poor. At present, a steam sweeper is used for cleaning floor stains, but the cleaning efficiency is low.

In view of the above technical problems, it is necessary to provide a cleaning device 10, wherein the cleaning device 10 has good cleaning effect and cleaning efficiency on the intractable stains. Also provided are a main body 100 and a cleaning robot 300 having the cleaning apparatus 10.

The cleaning device 10 includes: a steam generator 13, a housing 12, a steam passage 11, and a suction hole 114. The housing 12 is provided with a liquid storage tank 121, the liquid storage tank 121 is used for storing liquid, the steam generator 13 is communicated with the liquid storage tank 121, and the bottom wall of the housing 12 is provided with a steam outlet 122.

The steam channel 11 is arranged in the shell 12, the steam channel 11 comprises a reducing section 111 and an expanding section 113, one end of the reducing section 111 is communicated with the output end of the steam generator 13, the other end of the reducing section is communicated with the small-diameter end of the expanding section 113, the inner diameter of the reducing section 111 is gradually reduced from one end close to the steam generator 13 to one end close to the expanding section 113, and the inner diameter of the expanding section 113 is gradually enlarged from one end close to the reducing section 111 to one end far away from the reducing section 111. The large diameter end of the reducing section 111 is communicated with the steam generator 13, the small diameter end is communicated with the small diameter end of the expanding section 113, and the large diameter end of the expanding section 113 is communicated with the steam outlet 122. The suction holes 114 are opened in the diameter-reduced section 111 or in a side wall at a communication position between the diameter-reduced section 111 and the diameter-expanded section 113.

It will be appreciated that, when liquid (e.g. water) is supplied to the steam generator 13 via the reservoir 121, steam enters the reduced diameter section 111 of the steam channel 11, and then the reduced diameter section 111 has a gradually decreasing inner diameter, so as to throttle the steam, thereby increasing the flow rate of the steam in the reduced diameter section 111. Moreover, due to the throttling and pressure reducing effects, the steam speed is highest at the small-diameter end of the diameter reducing section 111, and the negative pressure generated at the small-diameter end is lowest. Therefore, the suction hole 114 is formed in the side wall at the connection of the small diameter section of the diameter reducing section 111 and the small diameter end of the diameter expanding section 113, so that the external air can be sucked into the steam channel 11 by effectively utilizing the pressure difference, thereby increasing the pressure of the steam.
