Description

Technical Field

[0001] The utility model relates to the technical field of air purifiers, in particular to a filtering device for air purifiers. Background Art

[0002] Air purifier, also known as "air cleaner", air refresher, purifier, refers to an air treatment device that can adsorb, decompose or transform various air pollutants and effectively improve the cleanliness of the air. It is widely used in various fields. The filter and filter element are one of the core components of modern air purifiers. Existing air purifier devices generally use flat filter. When this type of filter is used for a long time, dust easily accumulates on the surface and becomes clogged.

[0003] For example, a Chinese utility model patent with announcement number CN210278572U discloses a filter cleaning device for an air purifier. The filtering function of this solution is mainly achieved through filtering through the filter. In order to remove the accumulated dust, a cleaning mechanism is specially designed to clean the two side nets of the filter. However, the flat filter can only filter once for one air convection, and the straight airflow encountering the flat structure is more likely to be blocked. In view of this, a filtering device for an air purifier is proposed. Utility Model Content

[0004] In order to solve the technical problem of air purifier filtering, the utility model provides a filtering device for an air purifier.

[0005] The utility model is implemented by the following technical scheme: a filtering device for an air purifier, comprising a box body, a servo motor is fixedly connected to the upper side of the box body, an output end of the servo motor is fixedly connected to a spherical filter mesh rotatably connected to the lower side of the box body, an air introduction mechanism for delivering external air into the air purifier is arranged on one side of the box body, a dust cleaning mechanism for cleaning dust accumulated on the surface of the spherical filter mesh is arranged on the inner side of the box body, and an air outlet mechanism for discharging filtered air is arranged on the other side of the box body.

[0006] As a further improvement of the above solution, the air introduction mechanism includes an air supply channel connected to one side of the box body, a fan is arranged inside the air supply channel, and a flow control mechanism for regulating the air flow is arranged at the end of the air supply channel.

[0007] As a further improvement of the above scheme, the flow control mechanism includes a flow control surface fixedly connected to the end of the air supply channel, one side of the flow control surface is connected to the air duct, one side of the flow control surface is provided with upper and lower symmetrical limiting slide grooves, the inner sides of the two limiting slide grooves are respectively movably connected with two sliding doors that open and close each other, and one side of the flow control surface is provided with a sliding door driving mechanism for moving the two sliding doors closer or farther away.

[0008] As a further improvement of the above scheme, the sliding door driving mechanism includes connecting plates which are respectively rotatably connected to one side of the two sliding doors and simultaneously rotatably connected to one side of the flow control surface, one end of the two connecting plates are respectively fixedly connected with mutually meshing fan-shaped tooth plates, one side of one of the sliding doors is rotatably connected with a pull plate which is simultaneously rotatably connected to one side of the flow control surface, and one end of the pull plate is provided with a pull plate driving mechanism for rotating the pull plate.

[0009] As a further improvement of the above-mentioned scheme, the pulling plate driving mechanism includes a drawing wire fixedly connected to one end of the pulling plate and penetrating and slidably connected to one side of the air supply channel, the drawing wire transmission is connected to a limiting wheel rotatably connected to the lower side of the box body, the lower side of the box body is fixedly connected to a cylinder, and the output end of the cylinder is fixedly connected to a drawing reed fixedly connected to one end of the drawing wire.

[0010] As a further improvement of the above solution, the dust cleaning mechanism includes a sponge brush fixedly connected to both sides of the interior of the box and abutting against the outer side of the spherical filter.

[0011] As a further improvement of the above solution, the air outlet mechanism includes an exhaust channel mechanism connected to one side of the box body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model cooperates with the servo motor, the spherical filter, the box and the air duct. When the air first enters the spherical filter from the air duct, it is filtered once. When the air flows out from the spherical filter again, it is filtered once by the spherical filter. With one filter and one air convection, the air can be filtered twice, and the air purification effect is better.

[0014] 2. The utility model adopts a spherical filter with a special structural shape as the core filter element of the purifier. Because the part of the spherical filter involved in filtering is a spherical surface, the filtering area of ​​the air and the filter can be increased, so the filtering and purification effects are better.

[0015] 3. The utility model adopts a spherical filter, which makes the filter surface appear spherical and arc-shaped. Without considering the dust cleaning mechanism, the air purification gas filtering device is less likely to be blocked compared to the flat filter.

[0016] 4. The utility model cooperates with two sliding doors, connecting plates, pulling plates, wire drawing and cylinders. Under the condition of specific air supply power of the fan, by controlling the opening and closing degree of the two sliding doors, the air flow delivered to the spherical filter can be more flexibly controlled. The rotation speed and direction of the spherical filter can be controlled in conjunction with the servo motor, so as to achieve more accurate, efficient and energy-saving air purification quality.
