[0023] Since the air purifiers sold in the existing market suck dust through a filter screen, when the filter screen is used for a period of time and the filtration of the filter screen reaches the saturation value, the filter screen needs to be replaced. The filter screens of the existing air purifiers cannot be recycled and self-cleaned, and the price of replacing the filter screen is not low, resulting in low willingness of users to use air purifiers.

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments: An air purifier with a self-cleaning filter screen includes a purification body and a filter screen installed on the purification body. A cleaning component, a driving component and a fan component are arranged in the purification body. The cleaning component is also arranged at the air inlet of the purification body. The cleaning component is adjustably connected to the driving component. The fan component is arranged on the air duct of the purification body.

[0025] According to the air purifier with a self-cleaning filter screen of the present application, the present application adopts a cleaning component, a driving component and a fan component in the purification body and combines them with the filter screen, which can achieve the effects of air purification and filter screen cleaning. Among them, the cleaning component is used to collect the dust on the filter screen, and the driving component is used to adjust the movement of the cleaning component at the air inlet of the purification body. By rotating the fan component forward, air enters from the air inlet of the purification body, and the air is filtered by the filter screen to achieve air purification; by rotating the fan component in reverse, the cleaning component is adjusted to the air inlet of the purification body by the driving component, air enters from the air outlet of the purification body, the fan component blows air to the filter screen, and the dust particles in the filter screen are blown out. The cleaning component adsorbs the dust particles in the purification body to achieve the cleaning of the filter screen.

[0026] According to an embodiment of the present application, the cleaning assembly is provided with an electrostatic plate, and the electrostatic plate is adjustably connected to the driving assembly; a boosting module is further arranged inside the electrostatic plate, and the boosting module controls the output of 20 kV high voltage to enter the electrostatic plate. In the present utility model, dust on the filter screen is collected by the electrostatic plate. After voltage regulation by the boosting module arranged on the electrostatic grid, the power supply enters the life mode, and the boosting module will output 20 kV high voltage to enter the electrostatic plate, causing the air around the electrostatic plate to be ionized by the high-voltage electrostatic field generated by the static electricity, so that the dust in the air becomes charged and is then adsorbed on the electrostatic plate.

[0027] According to an embodiment of the present application, the driving assembly is provided with a lifting motor, and the electrostatic plate is connected to the lifting motor in a vertically adjustable manner. The function of the lifting motor is to control the lifting of the electrostatic plate module.

[0028] According to an embodiment of the present application, the fan assembly is provided with an impeller motor and a fan blade. The impeller motor is fixed on the purification body, and the fan is installed at the driving end of the impeller motor along the air duct of the purification body. By driving the fan blade to rotate forward by the impeller motor, air enters from the air inlet of the purification body, and the air is filtered by the filter screen; by driving the fan blade to rotate in reverse by the impeller motor and adjusting the electrostatic plate to the air inlet of the purification body by the lifting motor, air enters from the air outlet of the purification body, and the fan blade blows the filter screen to blow out the dust particles in the filter screen, and the dust particles in the purification body are adsorbed by the electrostatic plate.

[0029] According to an embodiment of the present application, the purification body is provided with an air inlet and an air outlet. The air outlet is arranged at the top of the purification body, and the air inlet is arranged on both sides of the purification body. When the fan assembly is arranged on the air duct in the purification body, the purification body has an air inlet and an air outlet, and the fan assembly is located below the fan assembly. By driving the fan blade to rotate forward by the impeller motor, air enters from the air inlet of the purification body, and the air is filtered by the filter screen; by driving the fan blade to rotate in reverse by the impeller motor and adjusting the electrostatic plate to the air inlet of the purification body by the lifting motor, air enters from the air outlet of the purification body, and the fan blade blows the filter screen to blow out the dust particles in the filter screen, and the dust is adsorbed and purified by the electrostatic plate.

[0030] According to an embodiment of the present application, the purification body is further provided with a receiving cavity, and the electrostatic plate is adjustably arranged in the receiving cavity. When the air purifier purifies air, the lifting motor drives the electrostatic plate to be received in the receiving cavity, and the filter screen works to achieve air purification. When the air purifier enables the self-cleaning function of the filter screen, the lifting motor is used to drive the electrostatic plate to the air inlet of the purification body. Since the impeller motor drives the impeller to rotate in the reverse direction, air enters from the air outlet of the purification body, the impeller blows air on the filter screen, and the air exits from the air inlet of the purification body. Therefore, it is necessary to drive the electrostatic plate to the air inlet of the purification body to adsorb and purify the dust particles in the filter screen by using the electrostatic plate.

[0031] According to an embodiment of the present application, the purification body is further provided with a first dust sensor, and the first dust sensor is used to detect the electrostatic plate in the receiving cavity.

[0032] According to an embodiment of the present application, the purification body is further provided with a second dust sensor, and the first dust sensor is used to detect the electrostatic plate at the air outlet in the cleaning mode.

[0033] According to an embodiment of the present application, the purification body is further provided with a liquid crystal display screen, and the liquid crystal display screen is electrically connected to the control module.

[0034] The main function of the present utility model: The solution of the present application is an improvement based on the filter screen structure of the air purifier product. In addition to being applied to this product, this circuit / control logic can also be applied to other product series with the same principle, such as floor sweepers, etc.

[0035] The basic working principle of the self-cleaning of the filter screen of the air purifier in the present application is: through reverse blowing and electrostatic adsorption of dust for self-cleaning of the filter screen.

[0036] The main components of the solution of the present application include: Conventional features: liquid crystal display screen, control module, dust sensor, filter screen, impeller motor, impeller and housing. Improved features: a lifting motor, whose function in the solution is to control the lifting of the electrostatic plate; an electrostatic plate, whose function in the solution is to collect the dust on the filter screen. Its basic property is that after the voltage is regulated by the boost module in the electrostatic plate, the power supply enters the boost module, and the boost module will output a high voltage of about 20KV into the electrostatic plate. The air around the electrostatic plate is ionized by the high-voltage electrostatic field generated by the electrostatic plate, so that the dust particles in the air are charged and then adsorbed on the electrostatic plate.

[0037] Based on the attachment Figure 1-2As shown, the complete working process of the solution composed of the above-mentioned various components is as follows: When the working time of the air purifier reaches the upper limit value set by the system, a cleaning prompt will pop up on the liquid crystal display screen. At this time, the user moves the air purifier to an outdoor space and presses the cleaning function in the liquid crystal display screen. After the control module receives the signal, it starts the lifting motor to lower the electrostatic plate module to the position of the cleaning mode as shown in the attached Figure 2 . After the electrostatic plate starts to generate an electric field and completes the electric field layout, the control module issues an instruction to start the impeller motor. The impeller motor rotates in reverse to drive the fan blade to generate a blowing wind. The air enters from the air outlet of the air purifier, passes through the inside of the filter screen, passes through the electrostatic plate, and then exits from the air inlet of the air purifier, as shown in the attached Figure 2 cleaning mode, and the arrow indicates the direction of the air flow. The wind generated by the fan blade blows out from the inside of the filter screen, blowing the dust adhering to the filter screen into the air, and the dust in the air is adsorbed on the electrostatic plate. The working time is controlled by the second dust sensor. When the second dust sensor detects that the dust reaches the set value, it sends a signal to the control module. After the control module receives the signal, it stops the impeller motor from working, closes the electrostatic plate, starts the lifting motor, and raises the electrostatic plate to the state of the Figure 1 purification mode. The liquid crystal display screen shows that the cleaning is completed. The user can remove the electrostatic plate, clean it, and then reinstall the air purifier, which can realize the function of self-cleaning of the filter screen.
