This locking mechanism 30 can facilitate the secure locking of the detachable side brush module 20 to the main housing 10 during installation of the detachable side brush module 20 to the main housing 10.

When the detachable side brush module 20 is mounted to the main housing 10, the main brush roll 104 and the side brush roll 205 are coupled by the connector 208 and both rotate simultaneously. In this example, the axis of rotation of the side brushroll 205 is collinear with the axis of rotation of the main brushroll 104. The side cover 103 is opened; the first connector 203 interfaces with the first interface 108, and the first connector 203 applies pressure toward the interior of the first interface 108. The valve 111 is opened by the valve core of the valve 111 moving under the pressure of the first joint 203; the liquid output channel in the main seat body 10 is communicated with the second liquid outlet hole 207 in the detachable side brush module 20; the second connector 204 is connected to the second interface 109 and the suction channel 107 in the main housing 10 communicates with a second suction nozzle 206 in the detachable side brush module 20.

As shown in fig. 8-9, when the main base 10 and the detachable side brush module 20 are simultaneously engaged in operation, the brush motor 112 drives the main brush roller 104 to rotate and simultaneously drives the side brush roller 205 to simultaneously rotate; the cleaning liquid in the cleaning supply tank 3 will be fed into the liquid output channel by the pump 113; in the main seat body 10, cleaning liquid in a liquid output channel overflows from a pair of first liquid outlet holes 105 and is supplied to the main brush roller 104, a fluff layer on the main brush roller 104 infiltrates the cleaned liquid and then wipes the ground in the rotating process, and the used liquid and dirt on the ground enter the first suction nozzle 106 under the suction action of the main brush roller 104 and the suction motor 6 and then enter the dirty liquid recovery tank 4; in the detachable side brush module 20, the cleaning liquid in the liquid output channel overflows from the second liquid outlet hole 207 and is supplied to the side brush roller 205, the fluff layer on the side brush roller 205 wets the cleaning liquid and then wipes the floor and the wall more equal area opposite to the floor in the rotating process, and the side brush roller 205 conveys the used cleaning liquid and dirt to the second suction nozzle 206 and then to the first suction nozzle 106 and then to the dirt liquid recovery tank 4.

When the detachable side brush module 20 is separated from the main base 10, the cleaning base 1 only depends on the main base 10 to perform surface cleaning, the main brush roller 104 performs surface cleaning, the side cover 103 covers one side wall of the main housing 101, the valve core of the liquid valve in the first interface 108 is at the initial position, the valve is in a closed state, cleaning liquid cannot flow out from the first interface 108, and the second interface 109 is in a sealed state due to the blocking of the side cover 103.

As shown in fig. 10, the above-described cleaning base in which the main base 10 and the detachable side brush module 20 are combined is well suited for cleaning along a wall area; during operation, the main brush roller 104 on the main base 10 is exposed from the first opening 115 to clean the floor, and the side brush roller 205 on the detachable side brush module 20 is exposed from the second opening 2013 and the opening 2012, so that the wall and the floor near the wall can be cleaned simultaneously along with the rotation of the side brush roller 205.

In other embodiments of the detachable side brush module, the detachable side brush module may also be provided without the second connector and the second suction nozzle, i.e. it is not in communication with the suction channel in the main housing after being attached to the main housing; the back of the side brush roller is provided with a recovery cavity, and under the high-speed rotation of the side brush roller, after the sewage and dirt are swept into the recovery cavity, the standby device is stopped to be used, and the detachable side brush module is detached from the main seat body and then the sewage and dirt in the recovery cavity are cleaned independently.

The cleaning base can be used for a vertical push rod type cleaning device, a horizontal type portable cleaning device, a portable cleaning device and the like, and can help clean interfaces such as wall surfaces and the like, so that the cleaning base is more convenient to use.
