In this embodiment, the airflow purification method of the cleaning robot includes the steps of:

and S10, starting the cleaning robot to operate. The cleaning robot can be started by touching a key or remotely started by the mobile terminal. Whether cleaning work can be carried out or not needs to be detected by oneself after the cleaning robot is started, for example, whether the storage box 30 is installed or not is detected, and a prompt is given if the storage box is not installed.

And S20, starting the purification assembly. After the cleaning robot is determined to be capable of performing cleaning work, the cleaning assembly 330 is turned on, the turning on of the cleaning assembly 330 includes turning on the light emitter 331 and turning on the ion generator 341, the light emitter 331 emits light towards the bottom case 310, the light emitted by the light emitter 331 can cover the suction opening 301, the air flow entering from the suction opening 301 is cleaned for the first time, and the light emitted by the light emitter 331 can reach the surface to be cleaned through the first light-transmitting area 312 and/or the second light-transmitting area 112, so that the cleaning robot performs sterilization and disinfection on the surface to be cleaned during the cleaning work.

If the cleaning robot enters a preset mode, the method goes to step S40 to turn off the cleaning assembly 330; if the cleaning robot does not enter the preset mode, the cleaning assembly 330 is continuously turned on. The cleaning robot entering the preset mode includes one of the following conditions:

under the first condition, the electric quantity of the cleaning robot is less than the preset electric quantity S301. Cleaning machines people is in carrying out the cleaning work in-process, can consume the electric quantity of battery continuously, cleaning machines people still is provided with sensor system 20, sensor system 20 can be used for detecting the electric quantity of battery including electric quantity monitoring sensor, and when the electric quantity of battery was less than predetermineeing the electric quantity, cleaning machines people need seek to retrieve and fill the seat and return and fill the seat and charge. In the process of finding and recovering the charging seat, the cleaning robot enters a preset mode, and the purification assembly 330 is closed, so that the consumption of the electric quantity of the battery is reduced, and the cleaning robot is prevented from being dead due to the exhaustion of the electric quantity in the process of finding the charging seat. The electric quantity detection sensor can obtain the current electric quantity of the battery through detecting information such as current or voltage.

In the second condition, the cleaning robot is in the charging state S302. The cleaning robot looks for a charging seat because the electric quantity is lower than the preset electric quantity, and if the cleaning robot is successfully docked for charging, the cleaning robot enters a preset mode and closes the purification assembly 330.

If the signal detected by the omni-directional wheel sensor is continuously output without a signal or continuously output with the same signal within a predetermined time period, it may be determined that the cleaning robot is in an abnormal working state. The driving part sensor may also be a sensor that detects driving motors of the left and right driving wheel assemblies, and when the cleaning robot is trapped, it is determined that the cleaning robot is in an abnormal working state by detecting that the current or voltage of the driving motors of the left and right driving wheels is in an abnormal state through the driving part sensor, and the cleaning robot enters a preset mode to control to close the cleaning assembly 330.
