Description

Technical Field

[0001] The present application relates to the technical field of air purifiers, and specifically discloses an indoor air purifier with a self-cleaning function. Background Art

[0002] Air purifier, also known as "air freshener", air cleaner, purifier, refers to a product that can absorb air pollutants and effectively improve the cleanliness of the air. Air purifiers are generally used indoors and mainly include a shell, fan and filter plate.

[0003] At present, most of the air purifiers on the market use fans and filter plates to purify the air. After a certain period of use, a lot of dust will accumulate on the filter plate. In order to prevent the filter plate from being blocked by excessive dust and to maintain good air circulation in the purifier during the purification process and ensure purification efficiency, people need to clean the filter plate regularly. At present, people usually disassemble the purifier manually to clean the internal filter plate, which is very troublesome.

[0004] Therefore, in view of this, the inventor provides an indoor air purifier with a self-cleaning function to solve the above-mentioned problem. Utility Model Content

[0005] The utility model aims to solve the problem that the existing air purifier needs to be disassembled to clean the internal filter plate, which is time-consuming and laborious.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides an indoor air purifier with a self-cleaning function, including a shell with air inlets and air outlets respectively arranged on two sides, a drainage structure for air intake arranged in the shell, and a filter plate arranged at the air inlet, characterized in that a dust collecting groove is provided on the shell at the bottom of the filter plate, a fixing frame for installing the filter plate is provided in the shell, knocking holes are provided at the four corners of the fixing frame, the four corners of the filter plate are placed in the corresponding knocking holes, and an electromagnet is also provided in the knocking hole, and a knocking structure that can attract the electromagnet and knock the filter plate is provided in the shell, a cleaning strip is vertically slidably connected to the fixing frame, the cleaning strip is attached to the filter plate and is used to clean the filter plate, and also includes a driving structure for driving the cleaning strip to slide up and down, a circuit structure for powering the electromagnet, and a control unit for controlling the operation of the driving structure and the switching of the circuit structure.

[0007] Furthermore, the drainage structure includes a fan arranged in the shell and a fresh plate arranged at one end of the fan close to the filter plate.

[0008] Furthermore, the driving structure includes a driving block fixed in the middle of the cleaning strip and provided with a threaded hole, a threaded rod threadedly connected to the driving block and rotatably connected in the shell, and a servo motor provided on the outer wall of the shell for driving the threaded rod to rotate.

[0009] Furthermore, the control unit includes a controller electrically connected to the servo motor, a power supply electrically connected to the controller, and the electromagnet is electrically connected to the power supply.

[0010] Furthermore, the knocking structure includes vertical rods fixed on both sides of the fixed frame, sleeves fixed on the vertical rods and facing the corresponding knocking holes, knocking columns slidably connected in the sleeves, permanent magnets arranged at the ends of the knocking columns, and reset springs for resetting the knocking columns.

[0011] Furthermore, a cleaning brush is provided at one end of the cleaning strip close to the filter plate.

[0012] Furthermore, the housing comprises a function box, a plurality of universal wheels arranged at the bottom of the function box, a telescopic column fixedly connected to the top of the function box, and a cleaning shell arranged at the top of the telescopic column.

[0013] The principle and effect of this scheme are:

[0014] 1. Compared with the prior art, the utility model uses a knocking structure to intermittently knock and vibrate the filter plate for cleaning, so that the dust tightly adhering to the filter plate can be cleaned, and then with the cleaning effect of the cleaning strip, the dust that is shaken and falls is scraped off to the dust collecting groove. When cleaning, it is only necessary to disassemble the dust collecting groove for dumping, and there is no need to manually disassemble the purifier, which solves the problem that the existing air purifier needs to disassemble the purifier to clean the internal filter plate, which is time-consuming and labor-intensive.

[0015] 2. The utility model controls the on-off of the driving structure and the electromagnet through the control unit provided, so that the electromagnet intermittently adsorbs the permanent magnet. When the permanent magnet approaches the electromagnet, it extends into the knocking hole and intermittently knocks the filter plate. When the electromagnet is powered off, the permanent magnet extends out of the knocking hole under the reset effect of the reset spring, thereby achieving the effect of reciprocating knocking on the screen, enhancing the cleaning effect, and causing the dust adhering to the filter plate to fall off. At the same time, the controller controls the rotation direction of the servo motor, so as to achieve the effect of the cleaning strip brushing the filter plate reciprocatingly up and down under the guiding effect of the guide groove, so that the cleaning effect is better.

[0016] 3. The utility model facilitates the movement of the purifier by means of universal wheels, and facilitates the adjustment of the height of the cleaning shell by means of telescopic columns, thereby making the use of the purifier more flexible. BRIEF DESCRIPTION OF THE DRAWINGS

A control unit for controlling the on-off of the driving structure and the electromagnet 13 is also included. The control unit includes a controller electrically connected to the servo motor, a power supply electrically connected to the controller, and the electromagnet 13 is electrically connected to the power supply. The servo motor is controlled to turn by the controller, so that the cleaning strip 102 can slide up and down and reciprocate to clean the filter plate 5.

[0029] The use process of the utility model is as follows:

[0030] The servo motor is started by the controller, and alternating current is supplied to the electromagnet 13 at the same time, so that the knocking column 1202 intermittently knocks the filter plate 5, and the cleaning strip 102 slides back and forth up and down, so that the dust adhering to the filter plate 5 is scraped and sent to the dust collecting groove. When cleaning is needed, it is only necessary to remove the dust collecting groove for cleaning. The utility model solves the problem that the existing air purifier needs to disassemble the purifier to clean the internal filter plate 5, which is time-consuming and labor-intensive.
