Surface cleaning machine of safe self-cleaning

Technical Field

The utility model relates to the field of cleaning electric appliances, in particular to a surface cleaning machine.

Background

Cleaning devices are a very important product in daily life and work, and with the wide application of electrical equipment and the gradual improvement of automation process, more and more electric cleaning devices are gradually accepted by people, such as sweeping robots, dust collectors, floor washing machines and the like. Some surface cleaning devices are provided with a machine body and a cleaning roller arranged on the machine body, and the machine body drives the cleaning roller to rotate so as to mop the ground. However, the existing surface cleaning device needs a user to detach the cleaning roller after use and manually clean the cleaning roller, so that the user experience is poor.

With the progress of the technology, people have invented an automatic cleaning device for a surface cleaning machine, which generally comprises a base, wherein the base comprises a seat body and a connecting part arranged on one side of the seat body, a cleaning roller of the surface cleaning machine is generally placed on the seat body, and the base is connected with a water tank and an air suction system of the surface cleaning machine through the connecting part so as to supply water in the water tank of the surface cleaning machine to the cleaning roller on the seat body and recycle sewage to a sewage tank of the surface cleaning machine so as to clean the cleaning roller. The base is simple in structure and solves the problem of automatic cleaning of the cleaning roller of the surface cleaning machine. However, in the use process of the base, the fact that in the cleaning process of the cleaning roller, if water is accumulated on the bottom surface too much, the cleaning roller is too wet, and after the cleaning is finished, a customer immediately cleans the cleaning roller; or accumulated water is left in the base, so that when a customer cleans the cleaning roller; or, when the customer washs in succession, the water that washs the scrub roller in the base has the danger of spilling over, can the secondary pollution bottom surface, and usually when wasing, the base is the circular telegram, has had liquid to spill over, and is not safe enough yet, and in addition, this self-cleaning device has only washd the scrub roller, and the soil pick-up mouth of cleaner always can not wash, and this place also is sewage or the place that the filth is concentrated moreover, breeds the bacterium easily.

The application number CN202011598658.9 entitled "chassis and cleaning system with it" discloses such a solution: the base comprises a seat part at least used for supporting a floor brush of the cleaning equipment; the floor brush is provided with a shell and a rolling brush which is rotatably arranged in the shell, and the shell is provided with an opening to allow part of the rolling brush to be exposed out of the shell; the electric auxiliary heating part is arranged on the seat part and is opposite to the rolling brush when the floor brush is placed on the seat part; the electric auxiliary heating part is used for carrying out auxiliary heating drying on the rolling brush after the power supply is switched on. The base that this application provided and have its clean system can carry out the heating drying to cleaning device's round brush, makes the round brush obtain rapid drying. The drying problem after the washing of round brush has been solved to this scheme, but still does not solve the overflow problem when water is too much, or the safety problem after the water spills over, and simultaneously, this patent also does not consider the washing problem of soil pick-up mouth.
