Description

Technical Field

[0001] The utility model relates to an air purifier with adjustable filtering pores. Background Art

[0002] The pore size of the filter unit of a traditional air purifier is fixed. When the pore size needs to be changed, it can only be achieved by replacing the filter unit, and dynamic adjustment of the pore size cannot be achieved. In addition, the life of the traditional filter unit is short, and it cannot effectively clean pollutants and air impurities. Frequent replacement is required, which is time-consuming, labor-intensive and costly. If it is not replaced, the purification effect will be reduced. Summary of the invention

[0003] The utility model provides an air purifier with adjustable filter aperture in order to solve the problems existing in the prior art.

[0004] The technical solutions adopted in this utility model are:

[0005] An air purifier with adjustable filter aperture comprises a filter barrel, a fan, an adjustment plate, a filter plate, a granular filter element and an electric linear actuator, wherein the filter barrel is provided with an air inlet and an air outlet, the air outlet end of the fan is connected to the air inlet, the adjustment plate and the filter plate are arranged in parallel in the inner cavity of the filter barrel, and the filter plate is fixed in position, mesh holes are arranged on the adjustment plate and the filter plate, a plurality of granular filter elements are arranged between the adjustment plate and the filter plate, and the electric linear actuator is placed on the outside of the filter barrel, and the electric linear actuator drives the adjustment plate to move toward the filter plate or away from the filter plate.

[0006] Furthermore, the electric linear actuator is an electric screw mechanism, which is arranged on one side of the air outlet of the filter barrel, and the linear free end of the electric screw mechanism extends into the filter barrel and is fixedly connected to the adjustment plate.

[0007] Furthermore, the granular filter element is a fiber ball.

[0008] Furthermore, a filter screen is provided at the air inlet end of the fan.

[0009] Furthermore, the air outlet of the filter barrel is connected to a plasma sterilization box or an ultraviolet sterilization box.

[0010] The utility model has the following beneficial effects:

[0011] The utility model can realize online or dynamic adjustment of the filter aperture, and can rotate freely according to different usage scenarios. When the filter unit (i.e., the fiber ball) needs to be cleaned, the fan is rotated in the opposite direction, and the fiber ball is blown by the fan regularly to achieve cleaning. The service life of the fiber ball is 2-3 times that of the traditional filter unit, which reduces the replacement frequency, reduces costs, and perfectly solves the problem of short service life of the fiber ball. The filter of the utility model can be replaced once every 2 years, which greatly reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1 and Figure 2 The utility model discloses an air purifier with adjustable filter aperture, comprising a filter barrel 1, a fan 2, an adjustment plate 3, a filter plate 4, a granular filter element 5 and an electric linear actuator 6.

[0019] The filter barrel 1 is provided with an air inlet 11 and an air outlet 12, the air outlet end of the fan 2 is connected to the air inlet 11, the filter plate 4 is fixed in the inner cavity of the filter barrel 1, and the outer wall surface of the filter plate 4 is in contact with the inner wall surface of the filter barrel 1, the adjustment plate 3 is movably arranged in the inner cavity of the filter barrel 1, and the adjustment plate 3 and the filter plate 4 are parallel to each other, and the gap between the outer wall surface of the adjustment plate 3 and the inner wall surface of the filter barrel 1 is less than 1mm. Meshes are provided on the adjustment plate 3 and the filter plate 4, the adjustment plate 3 is located on one side of the air inlet 11, and the filter plate 4 is located on one side of the air outlet 12, a plurality of granular filter cores 5 are arranged between the adjustment plate 3 and the filter plate 4, and the electric linear actuator 6 is placed on the outer side of the filter barrel 1, and the electric linear actuator 6 drives the adjustment plate 3 to move toward the filter plate 4, or away from the filter plate 4.

[0020] like Figure 3The electric linear actuator 6 in the present invention is an electric screw mechanism, including a motor 61 and an actuator screw unit 62. The motor 61 is arranged at one side of the air outlet of the filter barrel 1, and the actuator screw unit 62 is connected to the adjustment plate 3. The actuator screw unit 62 is a conventional mechanical actuator, so the present invention will not repeat its specific assembly and operation.

[0021] The granular filter element 5 in the utility model is a fiber ball, which utilizes fiber arrangement and electrostatic adsorption to filter, and has a good filtering effect.

[0022] A filter box is provided at the air inlet end of the fan 2, and a plurality of filter screens 7 arranged at intervals are provided in the filter box. The filter screens are provided to perform preliminary filtering and are used to filter out large particles such as flying catkins, hair fluff, etc.

[0023] The air outlet of the filter barrel 1 is connected to a plasma sterilization box or an ultraviolet sterilization box ( Figure 1 The middle component 13) is selected according to the actual use environment.

[0024] like Figure 4 This utility model is a set of integrated purification equipment customized for a certain manufacturer, which omits the filter 7 and component 13 (i.e., plasma sterilization box or ultraviolet sterilization box), and connects the air inlet to the purification box 8. When in use, it is equipped with a PID controller, a fuzzy controller and an air quality monitoring sensor. The specific circuit diagram is as follows Figure 5 The PID control module can automatically sense changes in air quality and intelligently adjust the pores to ensure that the air purifier operates efficiently at all times. Traditional filter units cannot adjust the porosity as air quality changes. After experimental comparison, taking 120㎡ as a reference, the use of our products increases the particle CADR value by 20%-30%, and it is estimated that 50-60 yuan in electricity bills will be saved each month.

[0025] When the filter unit (i.e., the fiber ball) needs to be cleaned, the filter screen 7 and the component 13 are completely removed. Figure 4 For application, the connection with the purification box 8 will be removed, and then the fan will be rotated in the reverse direction. The fiber balls will be blown with the fan regularly to achieve cleaning. The service life of the fiber balls is 2-3 times that of traditional filter units, which reduces the replacement frequency and reduces costs. It perfectly solves the problem of short service life of the fiber balls. The filter of the utility model only needs to be replaced once every 2 years, which greatly reduces costs.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
