Abstract
Description
Technical Field
[0001] This utility model relates to the field of air filtration, specifically a modular high-efficiency filter. Background Technology
[0002] High-efficiency air filters are primarily used to capture particulate dust and various suspended solids larger than 0.5μm. Air purifiers mainly consist of two parts: the filter element and the housing. The basic requirements are high filtration efficiency, low flow resistance, and the ability to operate continuously for extended periods to reduce subsequent consumable costs. The filter element, or air filter, plays a crucial role in the air purification industry.
[0003] However, after use, the filter elements in existing high-efficiency filters accumulate a lot of dust on their outer surface. When replacing them, the dust can easily fall into the high-efficiency filter, affecting its filtration efficiency. Utility Model Content

Detailed Implementation
[0020] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0021] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This is a schematic diagram of the structure of the present invention, a modular high-efficiency filter, including a sleeve 1 and an air filter element 2. The sleeve 1 is installed at the external air inlet, and the air filter element 2 is installed inside the sleeve 1.
[0022] After the outside air enters the sleeve 1, it passes through the air filter element 2 to intercept particulate dust and various suspended matter in the air, thereby purifying the air.
[0023] A collection mechanism 3 is slidably installed on the inner side wall of the sleeve 1. The air filter element 2 is installed in the collection mechanism 3. The collection mechanism 3 includes a frame 31, a first slot 32, a connecting frame 33 and a shielding pad 34. The frame 31 is slidably installed in the sleeve 1. The connecting frame 33 is sleeved on the outer side of the air filter element 2. The first slot 32 is opened on the inner side wall of the frame 31. The connecting frame 33 can be snapped into the first slot 32. The shielding pad 34 is installed on the side wall of the frame 31. The shielding pad 34 is in the shape of a U-shape.
[0024] Because the air filter 2 traps dust and suspended matter on its outside when filtering air, in order to prevent dust from falling into the sleeve 1 when replacing the air filter 2, this device is equipped with a frame 31 and a shielding pad 34 on the outside of the air filter 2, so that the air filter 2 can be wrapped inside, thereby collecting the dust and preventing the dust from falling into the sleeve 1.
[0025] One end of the sleeve 1 is fitted with a pre-filter 4, the output end of the pre-filter 4 is connected to the inner cavity of the sleeve 1, and the other end of the sleeve 1 is fitted with a fan 5, which is electrically connected to an external power source.
[0026] The pre-filter 4 proposed in this paper is a V-type pleated filter, which features a large filtration area, low resistance, and long service life. It pre-filters the air entering the sleeve 1, thereby effectively extending the service life of the internal air filter element 2.
[0027] A fixing ring 13 is sleeved on the outer wall of the fan 5. A threaded hole 6 is opened on the side wall of the fixing ring 13. A bolt 7 is screwed into the threaded hole 6. A top block 8 is installed at the end of the bolt 7. The top block 8 can be held against the side wall of the frame 31. A positioning hole 14 is opened on the side wall of the fixing ring 13. A pin 15 is inserted into the side wall of the sleeve 1. The pin 15 can be inserted into the positioning hole 14.
[0028] The fan 5 can be fixed by the engagement between the pin 15 and the positioning hole 14.
[0029] By using bolts 7 and top block 8, the air filter element 2 can be held in the sleeve 1 and its position can be fixed.
[0030] A sealing airbag 9 is fitted to the inner side wall of the sleeve 1. The sealing airbag 9 can fit against the outer side wall of the frame 31. A valve core 10 is inserted into the side wall of the sleeve 1. The valve core 10 is inserted into the sealing airbag 9.
[0031] By setting the sealing airbag 9, it can seal the gap between the frame 31 and the inner wall of the sleeve 1, preventing unfiltered outside air from entering the room;
[0032] The sealed airbag 9 can be inflated and deflated via the valve core 10.
[0033] A tie rod 11 is installed on the front side wall of the frame 31, and a clearance groove 12 is provided on the rear side wall of the frame 31, so that the tie rod 11 can be inserted into the clearance groove 12.
[0034] The pull rod 11 allows the frame 31 to be easily pulled out from the sleeve 1.
[0035] Bolt 7 includes screw 71, screw head 72, spring 73, top ring 74 and protrusion 75. Screw 71 is screwed into threaded hole 6. Screw head 72 is provided at the lower end of screw 71. Spring 73 is sleeved on the outside of screw 71. One end of spring 73 is connected to screw head 72. Top ring 74 is installed at the other end of spring 73. Protrusion 75 is installed on the lower wall of top ring 74. A second groove 16 is opened on the outer wall of fixing ring 13. Protrusion 75 can be inserted into the second groove 16.
[0036] By setting a spring 73, a top ring 74, and a protrusion 75 on the outside of the screw 71, after the screw 71 is tightened, the top ring 74 is held by the spring 73 and fits against the side wall of the fixing ring 13, and the protrusion 75 is inserted into the second slot 16, thereby preventing the screw 71 from rotating and avoiding loosening.
[0037] When this utility model is in operation, after the fan 4 is started, the fan 4 will draw outside air into the room through the sleeve 1. The outside air first passes through the pre-filter 4 to filter some large particulate impurities in the air, and then enters the sleeve 1. The air filter element 2 intercepts particulate dust and various suspended matter in the air, thereby purifying the air.
[0038] Because the air filter 2 traps dust and suspended matter on its outside when filtering air, in order to prevent dust from falling into the sleeve 1 when replacing the air filter 2, this device is equipped with a frame 31 and a shielding pad 34 on the outside of the air filter 2, so that the air filter 2 can be wrapped inside, thereby collecting the dust and preventing the dust from falling into the sleeve 1.
[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
