Self-propelled cleaning device

The present invention relates to a cleaning device, especially a self-propelled cleaning device with autonomous displacement for cleaning work.

According to the general self-propelled cleaning device, in order to be able to clean in various corners, the body is increasingly designed to be light, thin and small, and the functional mechanisms of the internal connection with the control device are increasingly positioned. Tightly, the electromagnetic radiation emitted by each functional device interferes with other functional mechanisms around it, resulting in so-called electromagnetic interference (EMI); and Patent No. 527176 "Autonomously Controlled Mobile Surface Treatment Equipment" A method for reducing electromagnetic interference is disclosed in which the battery case is positioned in a diameter opposite to a control module mounted on the frame or in the frame to minimize the influence of electromagnetic interference on the control module.

However, in the case of a shrinking self-propelled cleaning device, the use of positional distribution to reduce the degree of influence can not solve the problem of electromagnetic interference, and the source of electromagnetic radiation may be a self-propelled cleaning device in addition to the battery box. Other functional mechanisms, such as main, side brush or drive wheels in self-propelled cleaning devices The functional mechanism of the device and the like, and the electromagnetic radiation generated by the rotor and the stator in the opposite operation of the motor are far greater than the battery box, which can seriously affect the functions of other functional mechanisms or control devices around.

Therefore, the purpose of the present invention is to provide a self-propelled cleaning device that can reduce electromagnetic interference generated by an electromagnetic generating device to avoid affecting other surrounding devices or control devices having electromagnetic generation.

The self-propelled cleaning device according to the present invention includes: a first outer casing and a second outer casing, wherein the second outer casing is provided with a dust inlet, the first outer casing and the second outer casing are combined to form a receiving space; An electromagnetic generating source having an electromagnetic generating device is disposed in the accommodating space and electrically connected to a control device; a shielding layer is shielded between the devices having electromagnetic generation and is electromagnetically radiated by an anti-electromagnetic radiation The material is formed.

In the self-propelled cleaning device of the present invention, under the grouping of the shielding layer, the electromagnetic generating device generates electromagnetic radiation of different strength due to its own operation, and it has electromagnetic generation to the surrounding adjacent control device or the like. The electromagnetic interference generated by the device, especially the device with the motor driving function, such as the side brush device and the driving wheel device, is blocked by the shielding layer when the electromagnetic radiation generated by the device is scattered, and the other electromagnetic parts are reduced. The degree to which the generated device or control device is interfered by electromagnetic radiation, especially in the wireless receiving device and the remote control signal receiving device, can obtain better receiving effect due to the reduced degree of electromagnetic radiation interference.
