Description

Technical Field

[0001] The utility model belongs to the technical field of air filtration, and in particular relates to a handle for a pressable filter element. Background Art

[0002] The purpose of air filters is to obtain clean air that meets the standards. Generally, ventilation filters are used to capture and adsorb dust particles of different sizes in the air to improve the air quality and purify the air. Air filter elements are usually the most indispensable part of air purification devices.

[0003] The pressable drum filter element refers to an air filter element in the shape of a traditional drum or oval or similar drum. It is not limited to a circular state. The upper and lower plastic covers with shaping and sealing functions are cancelled and replaced with upper and lower covers made of soft materials to form an integrated air filter element. The soft material maintains the sealing effect. The soft material reduces the overall rigidity and softness of the filter element, making it easier to squeeze during packaging and transportation, reducing its original volume by 20%~80%, which is conducive to increasing transportation volume, reducing transportation costs, reducing transportation pollution, and reducing carbon emissions.

[0004] As a type of air filter element, the pressable cylindrical filter element is easily deformed by squeezing during transportation, and may not be able to fully return to its original shape during installation, resulting in loose sealing at the interface with the air filter. Loose sealing will cause air leakage, reduce filtration efficiency, and even affect the performance of the entire air filtration system; the soft material makes it difficult to grab and lift the filter element during installation and removal, especially in the absence of special tools or auxiliary devices, the operation is more difficult, which not only increases the maintenance cost, but also may cause damage to the filter element due to improper operation; long-term squeezing and deformation may damage the internal structure of the filter element, affecting its durability and service life. In addition, soft materials may be more susceptible to environmental factors (such as temperature, humidity, etc.), thereby accelerating the aging process; long-term squeezing and deformation may damage the internal structure of the filter element, affecting its durability and service life. In addition, soft materials may be more susceptible to environmental factors (such as temperature, humidity, etc.), thereby accelerating the aging process; loose sealing and reduced filtration efficiency will directly affect the overall performance of the air filtration system. This may result in substandard air quality, affect the quality and comfort of the indoor environment, and even pose a potential threat to personnel health. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 7 A specific implementation of a handle for a pressable filter element of the utility model is shown: it comprises a filter element introduction part 1, a filter element expansion part 2, a filter element pressure plate part 3 and a handle 4, wherein the filter element expansion part 2 is provided at the lower end of the filter element pressure plate part 3, and the filter element introduction part 1 is provided at the lower end of the filter element expansion part 2, and the handle 4 is mounted on the filter element pressure plate part 3; the inner diameter of the filter element expansion part 2 is 1-5 mm larger than the inner diameter of the pressable filter element, so after the filter element expansion part 2 is placed in the filter element, due to the interference fit between the inner diameter of the filter element, the structure can play the role of lifting the pressable cylindrical filter element;

[0027] The handle 4 is mounted on the upper surface of the filter element pressing plate portion 3 (such as Figure 1 as shown) or the middle (can be selected according to filter element and equipment requirements);

[0028] The handle 4 is a "straight" shape (such as Figure 2 as shown), "three-claw type" (as shown Figure 3 as shown) or the "four-claw" type (as shown Figure 4 As shown in the figure), it meets the operating habits of different users;

[0029] The filter element expansion part 2 and the filter element pressing plate part 3 are in the shape of a circular ring or a square ring (such as Figure 5 and Figure 7 As shown), it can be applied to filter elements of various shapes and sizes, thus improving the versatility and adaptability of the handle;

[0030] The filter element introduction portion 1 is in a cone shape, so that the filter element can be smoothly guided into the filter element expansion portion during installation.

[0031] During installation, the filter element introduction part first contacts with the pressable cylindrical filter element and is inserted into the inner hole of the pressable cylindrical filter element to make the filter element basically finalized. After the pressable cylindrical filter element completes the basic finalization, the filter element is fixed by the filter element expansion part and the filter element is formed into a regular circle.
