Technical Field

[0001] This utility model relates to the field of air filtration technology, specifically to an air filtration device for security equipment with replaceable filter elements. Background Technology

[0002] In the security field, air filtration devices are crucial for ensuring the cleanliness of the operating environment of equipment. As a core component, air filters use porous filter materials to capture dust from the gas-solid two-phase flow, thereby purifying the gas and ensuring the process requirements of clean rooms and the air cleanliness of general air-conditioned rooms.

[0003] However, some existing air filtration devices are not convenient enough when replacing the filter element. They require aligning the sealing plate with the opening of the filter box and then screwing in several screws to fix the sealing plate. The operation is relatively complicated, which increases the labor intensity of the user and results in low filter element replacement efficiency.

[0004] In addition, in some existing air filtration devices, the filtered dust and other impurities tend to fall to the bottom of the filter box during use, causing dust and other impurities to accumulate at the bottom of the filter box. Some devices do not have a structure for cleaning themselves, which increases airflow obstruction, affects the filtration efficiency and stable operation of the device, and increases maintenance costs.

[0023] 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.

[0024] Please see Figure 1-6As shown, an air filtration device for security equipment with replaceable filter cartridges includes a filter box 1. One side of the filter box 1 is connected to an air inlet 2, and the other side is connected to an air outlet 3, facilitating proper air filtration. A sealing plate 4 is hinged to the opening of the filter box 1. Handles 5 are slidably connected to both sides of the filter box 1. The handles 5 are C-shaped with inclined bottoms on both sides. Limiting mechanisms 6 are provided on both sides of the filter box 1, and limiting grooves 7 are formed on both sides of the sealing plate 4. The limiting mechanisms 6 and limiting grooves 7 cooperate with each other. A handle 16 is fixedly connected to the surface of the sealing plate 4, allowing users to easily pull open the sealing plate 4 to replace the filter cartridge. When the filter cartridge needs to be replaced, the user presses down... The handle 5, with its special shape, allows the limiting mechanism 6 to disengage from the limiting groove 7, thereby releasing the sealing plate 4 from its limit. At this point, pulling the handle 16 opens the sealing plate 4 upwards, preparing the necessary conditions for subsequent filter replacement. Similarly, to close the sealing plate 4, the user pulls the handle 16 downwards to close the sealing plate 4 and pulls the handle 5 upwards to disengage it from the limiting mechanism 6, allowing the limiting mechanism 6 to engage with the limiting groove 7 and fix the sealing plate 4. This reduces operational difficulty and improves the efficiency of filter replacement. Positioning blocks 8 are fixedly connected to both sides of the handle 5, and positioning grooves 9 are provided on the inner walls of both sides of the filter box 1. The surfaces of the positioning blocks 8 slide against the inner walls of the positioning grooves 9. The positioning block 8 and the positioning groove 9 work together to guide the handle 5 during movement, thus making the handle 5 more stable during movement. A fixed shell 10 is fixedly connected to the inner wall of the bottom of the filter box 1. A sliding groove is provided on one side of the fixed shell 10. There are three fixed shells 10, evenly distributed on the surface of the inner wall of the bottom of the filter box 1. A movable shell 11 is slidably connected to the inner wall of the fixed shell 10. A filter plate 12 is installed in the inner cavity of the movable shell 11. A cleaning scraper 13 is fixedly connected to the bottom of the movable shell 11. The cleaning scraper 13 is used to clean dust and other impurities that fall onto the inner wall of the bottom of the filter box 1 during use. The surface of the cleaning scraper 13 is slidably connected to the inner wall of the sliding groove on one side of the filter box 1. Made of rubber, when the filter plate 12 needs to be replaced, the user holds the surface of the filter plate 12 and pulls it outward, thereby moving the cleaning scraper 13 together. This scrapes away the dust and other impurities remaining on the inner wall surface at the bottom of the filter box 1, effectively reducing dust accumulation in the filter box 1, improving air circulation and filtration effect, and keeping the inner cavity of the filter box 1 relatively clean. A slider 14 is fixedly connected to one side of the cleaning scraper 13, and a groove 15 is provided on one side of the fixed shell 10. The surface of the slider 14 is slidably connected to the inner wall of the groove 15. With the cooperation of the slider 14 and the groove 15, the cleaning scraper 13 can be guided when moving, thereby making the cleaning scraper 13 more stable when moving.

[0025] The limiting mechanism 6 includes a mounting shell 61 fixedly connected to the inner wall of the filter box 1. A spring 62 is fixedly connected to the inner cavity of the mounting shell 61. A limiting block 63 is fixedly connected to one end of the spring 62. The limiting block 63 is C-shaped, and its surface is slidably connected to the inner wall of the mounting shell 61. The limiting block 63 cooperates with the limiting groove 7. Under this action, when it is necessary to open the sealing plate 4 to replace the filter plate 12, the user presses down on the handle 5. Due to the special shape of its bottom, the limiting block 63 is disengaged from the inner cavity of the limiting groove 7. Pulling handle 16 upwards opens the sealing plate 4, allowing the filter plate 12 to be replaced. Similarly, when the sealing plate 4 needs to be closed, the user pulls handle 16 downwards to close the sealing plate 4 and pulls handle 5 upwards to disengage handle 5 from the limiting block 63. Under the elastic force of spring 62, the limiting block 63 is inserted into the inner cavity of the limiting groove 7, thereby fixing the position of the sealing plate 4. This makes the process of replacing the filter plate 12 more convenient and faster, reduces the difficulty of operation, and alleviates the labor intensity of the user.

[0026] It is worth noting that the technical features such as filter plate 12 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0027] Working principle: When the filter plate 12 needs to be replaced, the user presses down on the handle 5. Due to its special shape at the bottom, it squeezes the limiting block 63 to overcome the elastic force of the spring 62 and move it outward from the mounting shell 61, thereby disengaging from the limiting groove 7 and releasing the limiting of the sealing plate 4. At this time, the user pulls the handle 16 to open the sealing plate 4 upward, preparing for the replacement of the filter plate 12. When replacing the filter plate 12, the user holds the surface of the filter plate 12 and pulls it outward, causing the moving shell 11 and the cleaning scraper 13 at its bottom to move accordingly. During the movement, the cleaning scraper 13 can scrape off the dust and other impurities remaining on the inner wall surface at the bottom of the filter box 1. This effectively reduces the accumulation of dust and other impurities on the inner wall surface at the bottom of the filter box 1, reduces airflow obstruction, lowers maintenance costs, and ensures stable operation of the equipment. After replacing the filter plate 12, the user pulls down the handle 16 to close the sealing plate 4, and then pulls up the handle 5 to disengage the handle 5 from the limiting block 63. Under the elastic force of the spring 62, the limiting block 63 moves outward from the mounting shell 61 and embeds into the inner cavity of the limiting groove 7, thereby fixing the position of the sealing plate 4. This completes the replacement of the filter plate 12 and the dust cleaning operation, thereby improving the convenience of operation, reducing the labor intensity of the user, and ensuring the stability of the device's operation.
