Description

A mobile indoor environment cleaning robot

technical field

The utility model relates to a robot with a clean air function, in particular to a robot with a clean air function and a cleaning function at the same time.

Background technique

At present, environmental pollution, especially air pollution is intensified, and PM2.5, formaldehyde, SO ₂ , and nitrogen oxides in the air have caused great harm to human health. Traditional air purifiers are usually placed in one place indoors for air purification. However, due to poor indoor ventilation, the purifier needs to perform a high-power intake and exhaust replacement cycle, and the air purification index cannot fully reflect the actual air in the entire room. The degree of purification causes the indoor air purification degree to be uneven. The mobile air purifier can clean a large area of air with less power during continuous mobile cruising.

At present, there are home-use sweeping robots on the market, whose main power is provided by a centrifugal fan, so the same fan can be used to provide power to clean the ground in all directions.

The Chinese patent application with the application number 201420138320.9 discloses a combination device for indoor air purification and floor cleaning, which includes a fixed body and a sweeping robot; the sweeping robot and the fixed body are connected through a charging interface; The control circuit, the identification signal transmitter and the power supply circuit connected by the signal between the purifier and the sweeping robot; The body is connected to the control module and the identification signal capture receiver through the charging interface. In this device, the air purifier and the sweeping robot are separated from each other. The sweeping robot needs to be disconnected from the fixed body when it is working, and returns to the fixed body to charge after completing the sweeping work. With such a design, the air purifier can only be installed at a fixed position indoors, so it is impossible to fully detect the indoor air condition. When the indoor space is large, it cannot complete the air purification of the entire indoor range well.

The Chinese patent application with the application number 201420539593.4 discloses an integrated machine for household air purification and automatic cleaning, including an air purifier, an electric control device and an operation panel. The self-propelled cleaning robot used, the electric control device includes a main control module arranged on the air purifier and a controlled module arranged on the cleaning robot, wireless communication between the main control module and the controlled module, on the operation panel A purification operation key for starting the work of the air purifier and a cleaning operation key for starting the work of the cleaning robot are provided. In this device, the cleaning robot is still separated from the air purifier when it is working. After the cleaning robot completes the cleaning work, it returns to the accommodation room below the air purifier. It can be seen that the air purifier in this device is still fixed and cannot be moved.

The Chinese patent application with the application number 201510822173.6 discloses an intelligent cleaning robot with air purification function, including a machine cover, a display operation panel box, a hinge shaft column, a buckle cover body, a base, a side brush motor, a side brush, and a cleaning component , driving wheel device, wheels, control circuit board, suction fan, suction motor, shock-absorbing suction sleeve and the suction port on its upper end, dust collection filter box and dust collection filter box seat groove and the dust inlet in it, and Suction port conversion device; the suction port conversion device is located in the suction port at the upper end of the shock-absorbing suction sleeve. composed of electromagnets. The space connected with the dust inlet in the dust collection box is divided into a dust collection room and a labyrinth filter room by a partition plate. The air inlet of the box body communicates with the first filter room of the dust collection room and the labyrinth filter room. First and second partitions are arranged at intervals, and the first and second partitions transversely separate the labyrinth filter chamber into first, second and third filter chambers. The functions of sweeping, vacuuming, mopping and purifying indoor air of the robot are integrated in the same body, which can be moved as a whole, and the dust filtration of the floor cleaning function and the filtration of the air purification function in the robot all adopt the same set of filtration system—— —The dust collection filter box is not only complicated in structure, but also affects the service life of the filter system.

Therefore, there is still a need for a cleaning robot that can achieve large-scale air purification, has a simple structure, and is easy to use.
