Description

Technical Field

[0001] The present invention relates to the technical field of filter devices, and more specifically to a ventilation filter device for environmentally friendly air purification equipment. Background Art

[0002] Environmentally friendly air purification equipment is a series of equipment specially designed to remove, reduce or control pollutants in the air. These equipment can filter, adsorb, decompose or transform harmful substances, particulate matter, gaseous pollutants, microorganisms and odors in the air, thereby improving indoor or outdoor air quality and protecting people's health and the environment.

[0003] Environmentally friendly air purification equipment works together through components such as chassis casing, ventilation and filtration devices, control systems, additional functions, power supplies and wires to filter and clean the air, providing people with a fresh and healthy living environment. Among them, the ventilation and filtration device is particularly important in environmentally friendly air purification equipment. It can filter particles and pollutants in the air, significantly improve air quality, protect people's respiratory health, and extend the service life of the equipment.

[0004] The shortcomings of the ventilation and filtration devices of existing environmentally friendly air purification equipment: First, the ventilation filter device uses fiber materials as filter media, such as glass fiber, polyester fiber or synthetic fiber. These fiber materials have different pore sizes and structures and can effectively intercept pollutant particles of different sizes. However, there will be particles between 0.1um and 0.5um in the air, and these particles cannot be effectively intercepted by the filter device, causing some fine particles to pass through the filter, resulting in inadequate filtration.

[0005] Second: As time goes by, dust, pollutants and bacteria in the air will gradually accumulate on the filter device. The accumulation of these impurities will not only reduce the efficiency of the filter component but also make the air purifier unable to achieve the expected air purification effect.

[0006] Third: In order to ensure that the air purification equipment can be used stably for a long time, the ventilation filter device needs to be replaced regularly to meet the filtering needs. When replacing, the screws, clips and other fixings on the filter device need to be removed, which is very troublesome. Summary of the invention

[0032] The working principle of the present invention is as follows: when the air purification device body 1 is used, external air enters the air purification device body 1 through the air inlet grille 101, the humidification mechanism 5 starts to work, the NE555 integrated chip 5023 is connected to the sprayer 5022 through the connecting line 5024, the parameters of the NE555 integrated chip 5023 are set according to the actual product needs, so as to control the vibration frequency of the sprayer 5022 to reach 113K Hz, the liquid is absorbed from the water tank 501 through the absorbent cotton 5021, and the liquid is directly transmitted to the sprayer 5022, and the NE555 integrated chip 5023 provides vibration for the sprayer 5022, and at this time the sprayer 5022 contacts the absorbent cotton After the moisture in 5021 is removed, it starts to work normally and mist appears. At this time, the fan 504 is started to quickly transmit the mist downward to ensure that the mist can be evenly distributed in the required area. At this time, the particles in the external air enter the air purification device body 1, and the water mist can adhere to the particles in the dry environment to increase their size, making it easier to capture and filter the particles in the air, making the filtration more sufficient; when it is necessary to clean the dirt attached to the surface of the filter body 2, the motor 401 is started to make the drive rod 402 start to rotate, and the transmission limit pin 4031 moves in the strip groove in the movable rod 403, thereby driving the transmission block 4032 to move left and right repeatedly, and the transmission block 4032 and the cleaning mechanism 40 4 is fixedly connected so that the brush plate 4044 drives the bar-shaped teeth 405 to move left and right, and the bar-shaped teeth 405 and the gear 406 are adapted to each other, so that the surface of the filter body 2 can be cleaned. The filter body 2 is S-shaped, and when cleaning the filter body 2, the brush plate 4044 moves along the wavy filter body 2. To ensure smooth movement, the brush plate 4044 moves on the round rod 4042, and to make the brush plate 4044 always fit with the surface of the filter body 2, the second spring 4043 will provide pressure on the back of the brush plate 4044 to make it fit with the filter body 2; when the filter body 2 needs to be cleaned, hold the lifting block 308 and pull it outward, at this time, the limit column 3 04 moves outward, and the first spring 306 begins to shrink under the action of the baffle 302 and the round block 305, and then the lifting block 308 is rotated to make the second parking surface 3071 contact with the first parking surface 3032.
