[0050] In this embodiment, a transmission chamber 26 is provided at one end of the lower shell body 2, and a limiting area 27 is provided at the other end of the lower shell body 2.

[0051] In this embodiment, the sealing cover 12 is provided with an air inlet 121, an air outlet pipe joint 122 and a wire hole 123 connected to the interior of the sealing cover 12, wherein the air inlet 121 is used for airflow exchange, the air outlet pipe joint 122 is fixedly connected to the suction pipe 71, and the wire hole 123 uses a threading rubber plug to fix the wire during the threading process and plays a certain waterproof sealing role.

[0052] On the other hand, an embodiment of the present invention further provides a method for heat dissipation of a cleaning head assembly, characterized in that the heat dissipation method comprises:

[0053] S1. A suspended rib plate 16 for supporting the motor 51 is provided at the bottom of the sealed cavity 11. By suspending the motor 51 in the air, the contact area between the motor 51 and the air is increased, and the flow of air is promoted.

[0055] S3. The other end of the suction pipe 71 is connected to the air outlet pipe joint 122 on the sealing cover 12 to communicate with the interior of the sealed cavity 11. The hole of the suction pipe 71 is arranged relative to the exhaust fan 72. The suction airflow is sucked by the suction pipe 71 and cooperates with the exhaust fan 72 to blow air inside the sealed cavity 11, thereby forming an air pressure difference between the inside and outside of the sealed cavity 11.

[0056] S4. When the suction system is running, the hot air flow inside the sealed cavity 11 is discharged to the suction pipe 71 with the assistance of the exhaust fan 72, and the hot air flow flows out of the sealed sealed cavity 11.

[0057] S5. After the hot air flow is discharged through the suction pipe 71, the cold air flow outside the sealed cavity 11 enters the interior through the air inlet 121. After this cycle, a heat dissipation system for cold and heat exchange is formed inside the sealed cavity 11.

[0058] To sum up, according to the heat dissipation method of this embodiment, since the heat exchange medium is air, in the suction system of the floor scrubber, a suction pipe is added to extend into the sealed cavity to cooperate with the exhaust fan, which can also achieve a very high heat dissipation effect. In this way, the device is made compact and lightweight, and air cooling is adopted, which is relatively cheap and has a simple structure.
