Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a vibration filter element structure for an air filter. Background Art

[0002] Air filter elements are components or elements in air filters used to filter air. They are usually made of specific materials and are used to remove impurities and pollutants in the air. These pollutants may include dust, pollen, bacteria, viruses, allergens, and harmful gases.

[0003] For example, an air filter element with publication number CN207356783U comprises a filter screen and two covers arranged at both ends of the filter screen, wherein the filter screen is folded into a wave shape, and mounting grooves for inserting the filter screen are provided on the end surfaces of the two covers facing the filter screen. The key point of the technical solution is that the filter screen is folded into a wave shape, so that the contact area between the filter screen and the air is increased under the same volume, and the air filter element provides a larger filtering area and a high filtering efficiency;

[0004] The above-mentioned comparative document increases the contact area between the filter and the air by folding the filter into a wave shape, thereby improving the filtration efficiency. Under the current technical conditions, after the filter element has been running continuously for a period of time, dust will accumulate on the filter element's outer surface. The adhesion of this dust will gradually reduce the filtration efficiency of the filter element. Given that the filter element is usually designed to have a longer service life, frequent replacement due to reduced filtration efficiency will cause unnecessary waste of resources. Utility Model Content

[0005] The utility model aims to provide a vibrating filter element structure for an air filter, so as to solve the problem that the filter element in the above-mentioned background technology is usually designed with a long service life, and if it is frequently replaced only due to the decrease of filtering efficiency, it will cause unnecessary waste of resources.

[0006] To achieve the above object, the utility model provides the following technical solution: a vibrating filter element structure for an air filter, comprising a sealing cylinder and a sealing cover, wherein the sealing cover is fixedly connected to the top of the sealing cylinder, an air inlet hole is arranged in the middle of the sealing cover, and a thread is arranged inside the air outlet hole;

[0007] A compression tube is fixedly connected to the bottom of the air outlet, and a vibration structure is provided at the bottom of the compression tube. The vibration structure is provided with a connection block, and a driving rod is rotatably connected inside the connection block. Support frames are fixedly connected to both sides of the driving rod, and a turbine is fixedly connected to the top of the driving rod, and the turbine is located inside the connection block;

[0008] A filtering structure for filtering air is arranged inside the sealing cylinder.

[0009] Furthermore, the connection block is fixedly connected to the bottom of the sealing cylinder, the support frame is configured as a frame structure, and clamps are provided at both ends of the support frame, and elastic paddles are clamped inside the clamps.

[0010] Furthermore, the outer shape of the turbine corresponds to the outer shape structure of the inner side of the compression tube, and both the turbine and the compression tube are configured as truncated cone structures.

[0011] Furthermore, the filtering structure is provided with an isolation cylinder, and a plurality of evenly distributed vents are provided on the side of the isolation cylinder, an isolation ring is fixedly connected to the top of the isolation cylinder, a fixing ring is fixedly connected to the top side of the isolation ring, and a filter net is fixedly connected inside the isolation cylinder.

[0012] Furthermore, the bottom of the isolation tube is fixedly connected to the inner bottom of the sealing tube, and a cavity is formed inside the isolation tube and the sealing tube.

[0013] Furthermore, the top of the fixing ring engages with the slot to seal the cavity formed inside the isolation tube and the sealing tube.

[0014] Furthermore, the outer side of the filter screen is fitted with the inner side of the isolation cylinder, and the filter screen is fixedly connected to the inner bottom of the sealing cylinder.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The air filter uses a vibrating filter element structure, which is provided with a vibrating structure. After being restricted by the truncated cone structure inside the compression tube, the airflow velocity is enhanced when passing through the inside thereof. This enhanced airflow then drives the turbine to rotate. As the turbine rotates, it drives the driving rod to rotate inside the connecting block. When the driving rod rotates, it drives the supporting frame to rotate. Therefore, the supporting frame drives the paddle to move inside the filter screen. During the contact process between the supporting frame and the filter screen, the filter screen is affected by the vibration of the supporting frame, so that the impurities on the outside thereof are shaken off.

[0017] Furthermore, a filtering structure is provided, firstly, the air is guided into the air inlet, and then the air is allowed to enter the space between the sealing cylinder and the isolation cylinder through the air inlet. During this process, the air will flow through the interior of the multiple vents, and finally be filtered through the filter screen. After the filtration, the air will enter the inside of the filter screen, and then pass through the compression tube, and finally be discharged from the air outlet to the outside of the device.

[0018] Furthermore, by fitting the isolation tube together with the outside of the filter, impurities on the outside of the filter can be effectively intercepted during their falling process. This design guides the impurities into the folds of the filter, thereby preventing the impurities from falling into the area between the isolation tube and the sealing tube, ensuring the cleanliness and purity of the internal structure and preventing potential contamination risks.

[0028] A vibration structure is provided. After being restricted by the truncated cone structure inside the compression tube 5, the airflow velocity is enhanced when passing through the inside thereof. This enhanced airflow then drives the turbine 8 to rotate. As the turbine 8 rotates, it drives the driving rod 7 to rotate inside the connecting block 6. When the driving rod 7 rotates, it drives the supporting frame 9 to rotate. Therefore, the supporting frame 9 drives the paddle to move inside the filter 15.
