Description

Technical Field

[0001] This utility model relates to the field of air purification equipment, and in particular to an air purification equipment with a multi-stage filtration structure. Background Technology

[0002] With the rapid development of modern times, the air in our environment has become polluted. When people inhale polluted air for a long time, it will affect their health and cause a series of health problems. At this time, air purification equipment is needed to purify the surrounding air. This equipment can purify indoor air, thereby improving living conditions and enhancing physical and mental health.

[0003] Air purifiers draw air in through the inlet, filter it through the filter element inside the filtration unit, and then circulate the filtered air through the outlet. Therefore, the airtightness of the filter element is crucial. Conventional filter elements achieve a seal by attaching sealing tape to their edges. However, after a period of use, the adhesive on these tapes tends to age, reducing the seal and causing air leakage at the edges of the filter element. This reduces the filtration efficiency. To address this issue, a multi-stage filtration structure for air purifiers is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an air purification device with a multi-stage filtration structure, which aims to improve the problem in the prior art that "the sealing adhesive is prone to aging, which reduces the sealing performance of the filter element assembly".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an air purification device with a multi-stage filtration structure, comprising a housing, a fixing seat fixedly connected to the inner wall of the housing, a top cover detachably connected to the top of the housing, a fixing mechanism provided inside the fixing seat, the fixing mechanism comprising a disc and a clamping block, the disc being rotatably connected to the inner wall of the fixing seat, a knob fixedly connected to the top of the disc, a control strip fixedly connected to the surface of the disc, the clamping block being slidably connected to the inner wall of the fixing seat, a filter plate inserted into the inner wall of the fixing seat, the surface of the filter plate contacting the surface of the clamping block, a pressure plate fixedly connected to the side of the clamping block away from the filter plate, and the side of the pressure plate away from the clamping block contacting the surface of the control strip.

[0007] The top of the outer casing is fixedly connected to the top cover by fixing bolts.

[0008] As a further description of the above technical solution:

[0012] As a further description of the above technical solution:

[0013] An activated carbon adsorption layer is provided at the end of the filter plate away from the clamping block.

[0014] As a further description of the above technical solution:

[0015] A handle is fixedly connected to the top of the filter plate.

[0016] As a further description of the above technical solution:

[0017] The top of the mounting base is provided with a ventilation slot, and the surface of the outer shell is provided with an air inlet.

[0018] As a further description of the above technical solution:

[0019] The surface of the top cover is provided with an air outlet, and a fan is fixedly connected to the bottom of the top cover.

[0020] This utility model has the following beneficial effects:

[0021] 1.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 This utility model provides an embodiment of an air purification device with a multi-stage filtration structure, including a housing 1, a fixing seat 2 fixedly connected to the inner wall of the housing 1, a top cover 3 detachably connected to the top of the housing 1, the top of the housing 1 being fixedly connected to the top cover 3 by fixing bolts 4 for easy maintenance and replacement of filter elements, a dustproof net 5 being provided on the top of the top cover 3, the dustproof net 5 being used to intercept large particles of dust, hair, etc., to prevent foreign objects and impurities from falling into the interior of the housing 1 from the air outlet 19 due to gravity, and a fixing mechanism 10 being provided inside the fixing seat 2.

[0032] Reference Figures 2-4The fixing mechanism 10 includes a disc 102 and a clamping block 105. The disc 102 is rotatably connected to the inner wall of the fixing base 2. A knob 101 with anti-slip texture is fixedly connected to the top of the disc 102 to reduce the possibility of slippage. A control strip 103 is fixedly connected to the surface of the disc 102. A circular protrusion is provided at the end of the control strip 103 away from the disc 102. The straight line of the control strip 103 is tangent to the arc edge of the disc 102. The rotation of the disc 102 drives the control strip 103 to rotate, thereby pushing the pressure plate 104 to clamp or release the filter plate 106 with the clamping block 105, ensuring that the filter plate 106 is stably installed.

[0033] Reference Figures 3-5 The clamping block 105 is slidably connected to the inner wall of the fixed base 2. A filter plate 106 is inserted into the inner wall of the fixed base 2. The filter plate 106 serves as a filter layer and can intercept solid particles such as PM10 and large dust particles. An activated carbon adsorption layer 107 is provided at the end of the filter plate 106 away from the clamping block 105. The activated carbon adsorption layer 107 on the surface of the filter plate 106 further removes volatile organic compounds such as formaldehyde and benzene, achieving efficient purification of gaseous pollutants. A handle 108 is fixedly connected to the top of the filter plate 106 to facilitate the removal and replacement of the filter plate 106.

[0034] Reference Figures 2-4 The surface of the filter plate 106 is in contact with the surface of the clamping block 105. A pressure plate 104 is fixedly connected to the side of the clamping block 105 away from the filter plate 106. The side of the pressure plate 104 away from the clamping block 105 is in contact with the surface of the control strip 103. Through the clamping force of the clamping block 105, the filter plate 106 is pressed against the inner wall of the fixed seat 2 to improve the sealing performance and prevent the air purification effect from decreasing due to the filter plate 106 not being properly sealed during the operation of the air purifier.

[0035] Reference Figures 1-3 The top of the fixed base 2 is provided with a ventilation groove 17, which optimizes the airflow distribution and ensures that the air passes evenly through the interior of the fixed base 2. The surface of the outer shell 1 is provided with an air inlet 18, which is located on the surface of the outer shell 1 and is used to guide the air to be purified into the interior of the outer shell 1. The surface of the top cover 3 is provided with an air outlet 19, and a fan 20 is fixedly connected to the bottom of the top cover 3. After the fan 20 is started, it creates a negative pressure, which draws in the outside air from the air inlet 18 on the side of the outer shell 1, and enters the filtration area through the ventilation groove 17 of the fixed base 2. The purified air is discharged from the air outlet 19 on the surface of the top cover 3.

[0036] Working principle: In use, the top cover 3 is installed on the top of the outer casing 1 by fixing bolts 4. The dustproof net 5 on the surface of the top cover 3 is used to intercept large particles of dust, hair, etc., to prevent foreign objects and impurities from falling into the interior of the outer casing 1 due to gravity from the air outlet 19. According to the purification needs, the user inserts the filter plate 106 into the inner wall of the fixing seat 2, so that the activated carbon adsorption layer 107 on one side of the filter plate 106 is aligned with the airflow direction. Then, the knob 101 is rotated to drive the disc 102 to rotate. The control strip 103 fixed on the edge of the disc 102... As the control bar 103 moves along the tangential direction, the circular protrusion at the end of the control bar 103 pushes the pressure plate 104 to move horizontally toward the filter plate 106. The movement of the pressure plate 104 causes the clamping block 105 to press the filter plate 106 against the inner wall of the fixing seat 2, thus completing the installation and fixing of the filter plate 106. By setting the fixing mechanism 10, the sealing performance of the filter plate 106 installation is improved, ensuring that there is no leakage between the filter plate 106 and the inner wall of the fixing seat 2, ensuring that the airflow is completely filtered by the filter plate 106, increasing the filtration resistance and thus improving the purification efficiency.

[0037] After the equipment is started, the fan 20 operates to generate suction, and outside air enters the interior of the outer casing 1 through the air inlet 18. It flows through the fixed base 2 to the filter plate 106. First, it passes through the activated carbon adsorption layer 107 to remove harmful gases such as formaldehyde and benzene, as well as odors. Then, it passes through the physical mesh of the filter plate 106 to intercept particulate pollutants such as dust and hair. The purified air continues to flow upward through the ventilation slot 17 at the top of the fixed base 2. After passing through the fan 20 at the bottom of the top cover 3, it is discharged from the equipment through the air outlet 19. The multi-stage filtration structure can further improve the air purification efficiency.

[0038] When the filter plate 106 needs to be replaced, rotate the knob 101 in the opposite direction. The rotation of the knob 101 causes the raised surface of the control strip 103 on the surface of the disc 102 to disengage from the pressure plate 104, thereby causing the clamping block 105 to release the filter plate 106. Then, the user can remove the old filter plate 106 for cleaning and replacement by pulling it up with the handle 108. With the cooperation of the fixing mechanism 10, the filter plate 106 can be quickly disassembled and stably fixed, reducing maintenance difficulty and improving work efficiency.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
