Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an air purifier filter housing structure. Background Technology

[0002] With the rapid development of industry, air pollution has become a serious challenge facing modern society, and air purification has also encountered prominent difficulties. The dust content in the air continues to rise, and the harm to human health is becoming increasingly serious. Against this backdrop, environmental protection companies have emerged, and the production of various air filtration equipment has gradually risen. As a result, air filter elements have become a popular product in the manufacturing industry, and the design of the air filter element bracket directly determines the shape of its overall structure.

[0003] Traditional filter cartridge installations are quite cumbersome, typically requiring multiple screws or complex clips to secure the cartridge inside the housing. Replacing the cartridge necessitates users using screwdrivers and other tools to individually remove the screws or unlock the clips, a time-consuming and laborious process. For users unfamiliar with the operation, this process is extremely difficult, often requiring professional assistance, increasing both operating costs and time.

[0004] Traditional solutions have significant flaws in their connection and sealing structure design. The connection between the upper and lower shells often uses a simple snap-fit ​​method without dedicated sealing strips or rubber gaskets, making it highly susceptible to air leakage from the gaps. Furthermore, the limiting and sealing structure between the filter element and the outer shell is inadequate; after installation, a gap exists between the filter element and the inner wall of the outer shell, allowing unfiltered air to escape directly through these gaps, severely reducing the air purification effect.

[0005] Traditional casings are mostly unibody structures, lacking modular design. When a part of the casing is damaged, the damaged part cannot be replaced individually; the entire casing must be replaced, which significantly increases repair costs. Furthermore, unibody structures are more difficult to manufacture, resulting in lower production efficiency. Utility Model Content

[0006] The purpose of this invention is to provide an air purifier filter housing structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air purifier filter housing structure, comprising a main body, an air outlet at the lower end of the main body, a filter element installed above the air outlet, a connecting module on the outer side of the filter element, and an air inlet above the connecting module.

[0008] Preferably, the air outlet includes an air outlet channel, a sealing ring is provided on the connecting flange at the lower end of the air outlet channel, a connecting groove is provided at the upper end of the sealing ring, and a first protruding ring at the lower end of the filter element is connected to the connecting groove.

[0009] Preferably, both the connecting groove and the first convex ring are provided with threads, and a sealing ring is provided at the bottom connection of the U-shaped groove.

[0010] Preferably, the connecting module includes a connecting ring, on which a second convex ring is connected to the bottom end of the upper shell and the top end of the lower shell, and a sealing tape is provided at the threaded connection.

[0011] Preferably, the air inlet includes an air inlet channel, a sealing ring is provided on the connecting flange at the upper end of the air inlet channel, and a filter screen is installed at the lower end of the air inlet channel by threads.

[0012] Preferably, the top of the filter element adopts an arc-shaped design. After the air enters the interior of the main body through the air inlet channel, it is guided to the surrounding area by the arc-shaped design, so that the filter element can filter the air comprehensively.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The air purifier's filter housing structure features an arc-shaped design at the top of the filter element that guides incoming air in all directions, ensuring comprehensive filtration and improving filtration efficiency and utilization. Multiple sealing designs are implemented throughout key connection points, including the sealing rings at the air outlet, the connecting grooves and protruding rings, the sealing tape on the connecting module, and the sealing ring at the air inlet, effectively preventing air leakage and ensuring purification performance.

[0019] 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.

[0020] Example: Please refer to Figure 1 This utility model provides a technical solution: an air purifier filter shell structure, including a main body 1, an air outlet 2 at the lower end of the main body 1, a filter element 3 installed above the air outlet 2, a connecting module 4 on the outer side of the filter element 3, and an air inlet 5 above the connecting module 4.

[0021] The air outlet 2 includes an air outlet channel 6. A sealing ring 7 is provided on the connecting flange at the lower end of the air outlet channel 6. A connecting groove 8 is provided at the upper end of the sealing ring 7. A first protruding ring 9 at the lower end of the filter element 3 is connected to the connecting groove 8.

[0022] In this embodiment, a sealing ring is installed on the lower flange of the air outlet duct to effectively prevent air leakage and ensure the airtightness of the duct. A precise fitting structure is formed by the connection groove engaging with the first protruding ring 9 at the lower end of the filter element, reducing the risk of loosening at the connection point. The matching design of the groove and the protruding ring requires no complex tools, facilitating the quick installation and replacement of the filter element.

[0023] Both the connecting groove 8 and the first convex ring 9 are provided with threads, and a sealing ring is provided at the bottom connection of the U-shaped groove.

[0024] In this embodiment, the threaded design connecting the groove and the convex ring enhances the connection's tightness, while the sealing ring at the bottom of the U-shaped groove further improves the sealing effect. The threaded connection itself has self-locking properties, and combined with the elastic compression of the sealing ring, it can reduce loosening problems caused by vibration. The standardized thread design facilitates mass production and is compatible with various specifications of connecting parts, reducing processing and maintenance costs.

[0025] The connecting module 4 includes a connecting ring 11, on which a second protruding ring 10 is connected between the bottom end of the upper shell and the top end of the lower shell of the main body 1, and a sealant is provided at the threaded connection.

[0026] In this embodiment, the connecting ring engages with the convex rings of the upper and lower shells of the main body to form a ring-shaped force-bearing structure, dispersing the pressure at the connection and improving overall stability. Sealing tape is applied to the threaded connection, which not only fills the thread gaps but also enhances leak-proof and moisture-proof capabilities, making it suitable for humid or dusty environments. The independent connecting ring structure facilitates the disassembly and assembly of the upper and lower shells of the main body, simplifying maintenance or component replacement procedures.

[0027] The air inlet 5 includes an air inlet channel 13. A sealing ring 7 is provided on the connecting flange at the upper end of the air inlet channel 13, and a filter screen 12 is installed at the lower end of the air inlet channel 13 by means of threads.

[0028] In this embodiment, a fine filter screen is threadedly installed at the lower end of the air inlet channel, which can pre-filter large particulate impurities in the air, reducing the burden on subsequent filter cartridges. The sealing ring of the upper connecting flange ensures a sealed connection between the air inlet channel and other components, while the lower fine filter screen provides preliminary purification, resulting in a high degree of functional integration. The threaded installation of the fine filter screen makes it easy to disassemble and remove, facilitating regular cleaning or replacement without the need for specialized tools.

[0029] The top of the filter element 3 is designed with an arc shape. After the air enters the interior of the main body 1 through the air inlet channel 13, it will be guided to the surrounding area by the arc shape so that the filter element can filter the air completely.

[0030] In this embodiment, the arc-shaped top guides the air entering the main body to the surrounding area, ensuring even airflow distribution across the filter element surface. This prevents excessive local filtration load and improves the overall utilization rate of the filter element. The arc design conforms to aerodynamics, reducing energy loss caused by airflow impact and minimizing noise while maintaining ventilation. The guiding effect ensures that all parts of the filter element participate evenly in filtration, preventing premature clogging and indirectly extending the filter element's replacement cycle.

[0031] Working principle: In actual use, outside air steadily enters the interior space of the main body 1 along the preset air intake channel 13. At this time, the fine filter 12 located at the lower end of the air intake 5 will take the lead in playing its role, acting as a solid barrier to accurately intercept and filter out larger debris such as hair and paper scraps mixed in the air. This step not only prevents large debris from clogging or damaging subsequent components, but also lays a good foundation for subsequent fine filtration.

[0032] The air, having passed through the initial filtration, continues to flow forward. When it reaches filter element 3, the unique arc-shaped structure at the top of the element cleverly guides the airflow. This arc design naturally disperses the concentrated airflow in all directions, allowing the air to pass evenly through all areas of the filter element. This ensures that every part of the filter element can fully participate in the filtration process, thereby efficiently and comprehensively removing dust, particulate matter, and other fine impurities from the air, resulting in cleaner filtered air.

[0033] After filtration and purification, the clean air gathers in the channel in the middle of the filter element and then flows smoothly out through the air outlet channel 6. The entire air supply and filtration process is coherent and orderly, ensuring the stable operation of the equipment.

[0034] When the equipment needs cleaning and maintenance after a period of use, the operation is very convenient. The operator can hold the upper or lower shell of the main body 1 and rotate the connection between it and the connecting ring 11. Using the threaded structure between the two, the upper and lower shells can be easily separated, so that the internal filter components can be fully exposed for thorough cleaning.

[0035] Meanwhile, the filter element 3 is extremely easy to disassemble and install. The first convex ring 9 at the lower end of the filter element and the connecting groove 8 at the upper end of the air outlet 2 adopt a precise matching design. With just a little force, the filter element can be quickly disassembled or installed. The whole process does not require complicated tools, which greatly improves the efficiency of cleaning and maintenance and ensures that the equipment can be quickly restored to its best working condition.

[0036] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
