As shown in fig. 1-3, an embodiment of the present utility model provides a cleaning device 100, which includes a housing 10, a heat generating component 20 and a suction assembly 30, wherein the heat generating component 20 is disposed on the housing 10, the suction assembly 30 is used for providing suction power for sucking external dirt into the cleaning device 100, and an air flow generated during operation of the suction assembly 30 dissipates heat of the heat generating component 20. The cleaning device 100 in the present application may be a floor scrubber, a cleaning robot, or the rest of the equipment for cleaning a surface.

According to the cleaning device 100 provided by the embodiment of the utility model, the heat dissipation and the temperature reduction of the heating element 20 are performed through the air flow generated during the working of the suction assembly 30, so that the serious heat generation of the heating element 20 is avoided, and the service life is prevented from being influenced.

The heat generating member 20 may be any component that is disposed on the cleaning device 100 and generates heat, and by way of example, the heat generating member may be a battery 20a and/or a PCB 20b (see fig. 5-7) and/or a vacuum pump, etc., the battery 20a is used to supply electric power, and the PCB 20b is used to control the operation of the cleaning device 100. In the embodiment of the utility model, the cleaning device 100 needs to be provided with the suction assembly 30 to suck external dirt into the cleaning device 100, so that the cleaning function is realized, the heat dissipation of the heat generating element 20 can be realized by utilizing the air flow generated by the suction assembly 30 during working, and the heat dissipation of the heat generating element 20 can be realized without additionally providing a heat dissipation device, so that the cost is reduced. At this time, the air flow generated when the suction assembly 30 operates may be an air inlet channel or an air outlet channel of the suction assembly.

Alternatively, as shown in fig. 3, the suction assembly 30 is mounted to the housing 10, and the suction assembly 30 may include a blower fan 30a and a driving circuit thereof. Of course, other power assemblies that provide airflow and draw external dirt into the cleaning device 100 may be used with the suction assembly 30.

In some embodiments, as shown in fig. 3 and 4, the cleaning apparatus 100 further includes an air flow channel 40, the air flow channel 40 being formed in the housing 10 and communicating with the suction assembly 30. In the present embodiment, the airflow is guided to dissipate heat from the heat generating component 20 by providing the airflow channel 40 communicating with the suction assembly 30.

In some embodiments, as shown in fig. 3 and 4, an air flow passage 40 communicating with the suction assembly 30 is formed in the housing 10, and an air outlet 41 of the air flow passage 40 faces the rear or obliquely rear of the cleaning device 100. In the present embodiment, the air outlet 41 is an end of the air flow channel 40, and the air outlet 41 faces the rear or the obliquely downward direction of the rear of the cleaning device 100. The rear direction here means a direction opposite to the forward direction of the cleaning device 100 in the non-turning state; the backward downward direction is a direction opposite to the forward direction of the cleaning device 100 in the non-turning state, and is inclined downward, so that the air flow from the air flow passage 40 can be blown toward the floor as much as possible. With this arrangement, the cleaning device 100 having the wet cleaning function (i.e. the cleaning device 100 needs water during cleaning and the surface passing through after cleaning is wet) can help the user to dry the cleaned surface as soon as possible and recover the drying as soon as possible.

During use, a user typically stands behind the floor washer, and the air outlet 41 is positioned on the handle assembly 120, since the floor washer is in an inclined position as shown in fig. 1, the air flow is directed toward the floor to dry the floor, rather than causing discomfort to the user. In addition, the cleaning device 100 may be a cleaning robot, and the cleaning device 100 does not need to be controlled by a user, but the cleaning device 100 itself is driven to perform surface cleaning, and the air outlet 41 faces the rear or downward direction of the cleaning robot, so that the air can be prevented from directly blowing to the user and drying the ground.

In some embodiments, as shown in fig. 3 and 4, the cleaning device 100 further includes a functional component 50, where the functional component 50 is detachably connected to the housing 10, and a gap exists between the functional component 50 and the housing 10, and the gap at least partially forms the air outlet 41.
