Description

Technical Field

[0001] This invention belongs to the field of air filtration technology, specifically relating to a combined high-efficiency air filter. Background Technology

[0002] As people's requirements for air quality continue to increase, air filters are becoming increasingly important in many fields such as daily life, industrial production, and medical care.

[0003] However, existing air filters often accumulate a large amount of impurities in their filter elements when performing air purification tasks, which significantly affects the filtration efficiency of the equipment. Furthermore, most high-efficiency air filters on the market adopt an integrated design, which makes the disassembly and installation of the filter element cumbersome and inconvenient for users to perform regular cleaning or replacement, further restricting the maintenance efficiency and ease of use of air filters. Based on the above problems, this application proposes a combined high-efficiency air filter to improve these issues.

[0004] Practical content

[0005] The purpose of this utility model is to provide a combined high-efficiency air filter that allows the operator to press a knob on one side of the housing when cleaning or replacing the filter plate. This moves the filter plate and compresses the spring. Rotating the knob disengages the retaining plate from the retaining slot. Releasing the knob pushes the spring to move the filter plate toward the knob, enabling quick disassembly of the filter plate. This significantly saves maintenance time and labor costs, and effectively ensures the continuous operation of air filtration.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A combined high-efficiency air filter includes a housing. Multiple filter plates are arranged sequentially from top to bottom inside the housing. A circular groove is formed on one side of each filter plate. A knob is rotatably connected inside the circular groove. A fixing block is fixed to one side of the housing, at both the upper and lower ends of the knob. A retaining plate is fixed to the outside of the knob. A retaining groove is formed inside the fixing block, and the retaining plate and the retaining groove are compatible. A support block is fixed to the side of the housing away from the fixing block. A spring is arranged inside the support block. A top post is arranged on the side of the spring near the housing. One side of the top post penetrates the support block and extends into the interior of the housing, and the support block and the top post are slidably connected.

[0008] In a preferred embodiment, the filter plate has grooves at both ends, and slide rods are fixed inside the housing at both ends of the filter plate, with the grooves and slide rods being compatible.

[0009] In a preferred embodiment, the outer side of the knob is provided with anti-slip texture, and the anti-slip texture is made of rubber.

[0010] In a preferred embodiment, a first connecting plate is fixed to the lower end of the outer side of the housing, a collection box is provided at the lower end of the housing, a second connecting plate is fixed to both ends of the collection box, and the first connecting plate and the second connecting plate are fixedly connected by bolts, a limit plate is fixed to the upper end of the collection box, a limit groove is provided at the lower end of the housing, and the limit plate and the limit groove are compatible.

[0011] In a preferred embodiment, a sealing ring is fitted on the outer side of the limiting plate.

[0012] In a preferred embodiment, an air inlet pipe is provided at one end of the housing, and an air outlet pipe is provided at the upper end of the housing.

[0013] The technical effects achieved by this utility model are as follows:

[0014] When the filter plate needs cleaning or replacement, press the knob towards one side of the housing. The knob moves, causing the filter plate to move. The movement of the filter plate pushes the top column to compress the spring. When the filter plate stops moving, turn the knob to disengage the locking plate on the knob from the locking groove on the fixing block. Loosen the knob, and under the action of the spring, the top column pushes the filter plate towards the knob. At this point, the filter plate can be quickly disassembled for cleaning or replacement, greatly saving maintenance time and labor costs and ensuring the continuity of air filtration.

[0027] Please see the appendix Figures 1 to 4 As shown, this utility model provides a combined high-efficiency air filter, including a housing 10. Multiple filter plates 11 are arranged sequentially from top to bottom inside the housing 10. A circular groove 12 is formed on one side of each filter plate 11. A knob 13 is rotatably connected inside the circular groove 12. Fixing blocks 14 are fixed to one side of the housing 10, at the upper and lower ends of the knob 13. A retaining plate 15 is fixed to the outside of the knob 13. A retaining groove 16 is formed inside the fixing block 14, and the retaining plate 15 and the retaining groove 16 are compatible. A support block 17 is fixed to the side of the housing 10 away from the fixing block 14. A spring 18 is arranged inside the support block 17. A top post 19 is arranged on the side of the spring 18 near the housing 10. One side of the top post 19 passes through the support block 17 and extends into the interior of the housing 10, and the support block 17 and the top post 19 are slidably connected.

[0028] In this embodiment, in the initial state, the spring 18 pushes the top post 19 with elastic force. Since one side of the top post 19 passes through the support block 17 and extends into the interior of the housing 10, the top post 19 and the housing 10 are slidably connected. The side of the top post 19 away from the spring 18 acts on the filter plate 11. Since the side of the filter plate 11 away from the top post 19 has a circular groove 12, a knob 13 is rotatably connected inside the circular groove 12. A locking plate 15 is fixed to the outside of the knob 13. The upper and lower ends of the knob 13 are respectively provided with fixing blocks 14, and the fixing blocks 14 are fixedly connected to the housing 10. The sides of the two fixing blocks 14 that are close to each other have slots 16. The locking plate 15 is perpendicular to the two fixing blocks 14. At this time, the locking plate 15 is located inside the slots 16 inside the fixing blocks 14. The filter plate 11 is locked inside the housing 10 under the action of the top post 19, the spring 18, the locking plate 15, and the fixing blocks 14.

[0029] When the filter plate 11 needs to be replaced or cleaned, the operator pushes the knob 13 towards the side closer to the housing 10. At this time, the knob 13 moves the filter plate 11 towards the support block 17. When the filter plate 11 moves, it pushes the top column 19 to compress the spring 18. When the filter plate 11 stops moving, the knob 13 is turned to disengage the retaining plate 15 from the retaining groove 16. At this time, the retaining plate 15 and the two fixing blocks 14 are parallel, and the horizontal limitation of the filter plate 11 is released. At the same time, due to the elastic force of the spring 18, the top column 19 will push the filter plate 11 slightly out a distance, making it convenient for the operator to pull the filter plate 11 out of the housing 10. When installing a new filter plate 11, first insert the filter plate 11 along the inside of the housing 10. When the filter plate 11 reaches the designated position, the spring 18 is compressed. Then, turn the knob 13 to make the locking plate 15 re-lock into the slot 16, so that the locking plate 15 and the two fixing blocks 14 are perpendicular, thereby fixing the filter plate 11 firmly in the housing 10.

[0030] It should be noted that inside the housing 10, multiple filter plates 11 are arranged sequentially from top to bottom. The bottommost filter plate 11 has large pores and is mainly responsible for intercepting larger particles in the air, such as large dust particles. Next to it is the medium-pore filter plate 11, which captures smaller impurities that escaped the large pores. The topmost fine-pore filter plate 11, with its tiny pores, filters out extremely fine particles, including fine dust and some microorganisms. As air passes through these three layers of filter plates 11 with different pore sizes, various impurities in the air are trapped layer by layer. After filtration, under the influence of gravity, they fall downwards and eventually flow into the collection box 23 located at the lower end of the housing 10. This achieves graded filtration of particles of different diameters in the air, ensuring that the discharged air is cleaner.

[0031] In a preferred embodiment, please refer to Figure 3Both ends of the filter plate 11 are provided with sliding grooves 20, and both ends of the filter plate 11 are fixed inside the housing 10, and the sliding grooves 20 and the sliding rods 21 are compatible.

[0032] In this embodiment, the slide bar 21 cooperates with the slide groove 20 to provide precise guidance for the installation of the filter plate 11, ensuring that the filter plate 11 is accurately installed in the designated position and avoiding the filter plate 11 from shifting or tilting during the installation process.

[0033] Secondly, please refer to again Figure 4 The outer side of knob 13 has anti-slip texture, which is made of rubber.

[0034] In this embodiment, the anti-slip texture of the rubber material significantly increases the friction between the user's hand and the knob 13. When operating the knob 13, whether turning it clockwise or counterclockwise, the user can apply force more easily and stably, avoiding difficulty in turning the knob 13 due to slippage, making the operation process smoother and improving operating efficiency.

[0035] Secondly, please refer to the following as well. Figure 5 and Figure 6 A first connecting plate 22 is fixed to the lower end of the outer side of the housing 10. A collection box 23 is provided at the lower end of the housing 10. A second connecting plate 24 is fixed to both ends of the collection box 23. The first connecting plate 22 and the second connecting plate 24 are fixedly connected by bolts. A limit plate 25 is fixed to the upper end of the collection box 23. A limit groove 26 is opened at the lower end of the housing 10. The limit plate 25 and the limit groove 26 are compatible.

[0036] In this embodiment, during installation, the limiting plate 25 is first aligned with the limiting groove 26 and slid in to achieve initial positioning. Then, bolts are passed through the threaded holes of the aligned first connecting plate 22 and second connecting plate 24 and tightened. During operation, impurities filtered from the housing 10 fall into the collection box 23 under gravity. Due to the connection between the limiting plate and the bolts, the collection box 23 is stably fixed. When cleaning is required, the bolts are removed, allowing the limiting plate 25 to slide out of the limiting groove 26 and separate the collection box 23. After cleaning, it is reinstalled according to the installation steps and put back into use.

[0037] To further understand and explain, Figure 5 For example, a sealing ring is fitted on the outer side of the limiting plate 25.

[0038] In this embodiment, the sealing ring (not shown in the figure) can fill the gap between the limiting plate 25 and the limiting groove 26, effectively preventing air or other fluids from leaking from the connection between the collection box 23 and the housing 10.

[0039] In a preferred embodiment, please refer to Figure 1 An air inlet pipe 27 is provided at one end of the housing 10, and an air outlet pipe 28 is provided at the upper end of the housing 10.

[0040] In this embodiment, during operation, the induced draft fan draws outside air into the inlet duct 27. The air flows into the housing 10 through the inlet duct 27. The air entering the housing 10 is filtered through multiple layers of filter plates 11, effectively intercepting impurities such as dust, particles, and microorganisms. At the same time, the exhaust fan operates, creating a negative pressure at one end of the exhaust duct 28, which causes the purified air to quickly pass through the exhaust duct 28 and be delivered to the target area. The induced draft fan and exhaust fan are existing technologies and will not be described in detail.

[0041] The working principle of this utility model is as follows:

[0042] Initially, the filter plate 11 is secured within the housing 10 by the top post 19, spring 18, clamping plate 15, and fixing block 14. When replacing or cleaning the filter plate 11, the operator pushes the knob 13, causing the filter plate 11 to compress the spring 18. Rotating the knob 13 disengages the clamping plate 15 from the clamping groove 16, and the spring 18 pushes the filter plate 11 out for extraction. Impurities filtered by the filter plate 11 fall into the collection box 23 by gravity. When the collection box 23 needs to be cleaned, the bolts are removed, allowing the limiting plate 25 to separate from the limiting groove 26 and remove the collection box 23. The sealing ring on the outside of the limiting plate 25 prevents air or fluid from leaking from the connection between the collection box 23 and the housing 10.

[0043] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
