Description

Technical Field

[0001] This utility model provides an air filter with a long service life, belonging to the field of air filter technology. Background Technology

[0002] Air filters are mainly used in pneumatic machinery, internal combustion machinery, and other fields. Their function is to provide clean air to these machines, preventing them from drawing in air containing impurities that could increase the likelihood of erosion and damage. The main components of an air filter are the filter element and the filter housing. The filter element is the primary filtration component, responsible for filtering the gas, while the filter housing is the external structure that provides necessary protection for the filter element.

[0003] Existing air filters generally meet normal usage needs. Air filters are fixed in suitable positions using brackets, but these brackets typically only provide support and often lack vibration damping. When the air filter supplies clean air to operating internal combustion engines such as diesel generators, the filter body inevitably vibrates. Because there is no effective vibration damping, the air filter body is at relatively high risk of damage, thus affecting its lifespan. Therefore, this invention provides an air filter with a long service life. Utility Model Content

[0004] The technical problem solved by this utility model is that the bracket does not have a shock absorption function, and it cannot effectively absorb vibration when the air filter body vibrates. The air filter body is at relatively high risk of being damaged by vibration, which affects and reduces the service life of the air filter.

[0005] To solve the technical problem, the technical solution provided by this utility model is as follows: an air filter with a long service life, including an air filter body, and a left support part and a right support part fixedly installed below the air filter body and having the same structure. The left support part includes a base and a bracket located above the base. Hollow plates passing through the bracket are symmetrically arranged on both sides of the top of the base. Bottom plates elastically connected to the bottom of the hollow plates are arranged on both sides of the bottom of the bracket. Shock-absorbing pads are provided at the bottom of the base.

[0006] A shock-absorbing assembly is provided between the left support and the right support. The shock-absorbing assembly includes a support rod fixedly installed on the side wall of the hollow plate, and hollow rods are elastically connected between the support rods in the same direction.

[0007] Furthermore, the air filter body has an air inlet cap at the top input end, an air outlet bend hose at the side output end, a connecting steel pipe at the port of the air outlet bend hose, and a reducing straight hose at the port of the connecting steel pipe.

[0008] Furthermore, the air filter body includes an air filter cylinder, and the air filter cylinder is provided with a main filter element and a safety filter element in sequence from the outside to the inside. A dust removal bag is provided at the bottom of one side wall of the air filter cylinder.

[0009] Furthermore, a rubber buffer sleeve is provided between the bottom of the hollow plate and the bottom of the base plate, and springs with dampers are provided on both sides of the rubber buffer sleeve.

[0010] Furthermore, the end of the support rod is slidably connected to the inner wall of the hollow rod, a partition plate is provided between the inner walls of the hollow rod, and a spring equipped with a damper is provided between the end of the support rod and the side wall of the partition plate.

[0011] Furthermore, the base plate is slidably connected to the inner wall of the hollow plate, and the two inner walls of the hollow plate are symmetrically provided with limiting rails that match the base plate.

[0012] The beneficial effects of this utility model are:

[0013] Vibration is absorbed and energy is dissipated through the left and right support parts, rubber buffer sleeves, and spring 1 equipped with a damper. The simple harmonic vibration of spring 1 is suppressed. The vibration is transmitted to the base and further damped by the damping pad. After the vibration is transmitted to the hollow plate, it is further damped and energy dissipated by the damping component under the action of spring 2 equipped with a damper. The simple harmonic vibration of spring 2 is suppressed, and damping force is generated. In this way, the vibration force can be effectively offset, improving the buffering and damping effect, effectively damping the air filter body, reducing the risk of air filter body being damaged by vibration, and resulting in a relatively long service life.

Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0022] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0023] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] According to the appendix Figure 1-4 As shown: This utility model provides an air filter with a long service life: it includes an air filter body 1, an air inlet cap 2 at the top input end of the air filter body 1, an air outlet bend hose 13 at the side output end of the air filter body 1, a connecting steel pipe 14 at the port of the air outlet bend hose 13, and a reducing diameter straight hose 15 at the port of the connecting steel pipe 14. The air filter body 1 includes an air filter cylinder 16, and a main filter element 17 and a safety filter element 18 are arranged sequentially from the outside to the inside of the air filter cylinder 16. A dust removal bag 19 is provided at the bottom of one side wall of the air filter cylinder 16. Specifically, the air entering the air filter body 1 from the air inlet cap 2 is filtered by the main filter element 17 and the safety filter element 18, and finally discharged from the reducing diameter straight hose 15 through the air outlet bend hose 13 and the connecting steel pipe 14, for the purpose of filtering the air.

[0025] As per the instruction manual Figure 1 , 2As shown in Figure 5, the system also includes a left support 3 and a right support 4, which are fixedly installed below the air filter body 1 and have the same structure. The left support 3 includes a base 5 and a bracket 6 located above the base 5. Hollow plates 7 are symmetrically arranged on both sides of the top of the base 5, passing through the bracket 6. Bottom plates 8 are elastically connected to the bottom of the hollow plates 7 on both sides of the bottom of the bracket 6. The bottom plates 8 are slidably connected to the inner sidewalls of the hollow plates 7. The two inner sidewalls of the hollow plates 7 are symmetrically provided with limiting rails 24 that match the bottom plates 8, which serve to limit the bottom plates 8. A rubber buffer sleeve is provided between the bottom of the hollow plates 7 and the bottom of the bottom plates 8. 20. Springs 21, which are installed on both sides of the rubber buffer sleeve and equipped with dampers, reduce vibration and dissipate energy, suppressing the simple harmonic vibration of springs 21. The bottom of the base 5 is equipped with a shock-absorbing pad 9, which plays a role in shock absorption. Specifically, when the air filter provides clean air to the working internal combustion engine equipment such as diesel generators, the air filter body 1 will inevitably vibrate. The vibrating air filter body 1 drives the bracket 6 to vibrate. The rubber buffer sleeve 20 and the springs 21 equipped with dampers reduce vibration and dissipate energy, thereby effectively offsetting the vibration force and effectively reducing the vibration of the air filter body 1.

[0026] As per the instruction manual Figure 2 , 6 As shown: A damping assembly 10 is provided between the left support part 3 and the right support part 4. The damping assembly 10 includes a support rod 11 fixedly installed on the side wall of the hollow plate 7. A hollow rod 12 is elastically connected between the support rods 11 in the same direction. The end of the support rod 11 is slidably connected to the inner side wall of the hollow rod 12. A partition plate 22 is provided between the inner side walls of the hollow rod 12. A second spring 23 equipped with a damper is provided between the end of the support rod 11 and the side wall of the partition plate 22. Specifically, after the vibration is transmitted to the hollow plate 7, it can be transmitted to the support rod 11. Under the action of the second spring 23 equipped with a damper, the vibration is further reduced and the energy is dissipated, suppressing the simple harmonic vibration of the second spring 23 and generating a damping force.

[0027] The principle of this utility model

[0028] When the air filter provides clean air to operating internal combustion engine equipment such as diesel generators, the air filter body 1 will inevitably vibrate. Through the left support part 3 and the right support part 4, the vibrating air filter body 1 drives the bracket 6 to vibrate. The rubber buffer sleeve 20 and the spring 21 equipped with a damper absorb the vibration and dissipate the energy, suppressing the simple harmonic vibration of the spring 21. The vibration is transmitted to the base 5 and further damped by the shock-absorbing pad 9. After the vibration is transmitted to the hollow plate 7, it is transmitted to the support rod 11 through the shock-absorbing component 10. Under the action of the spring 23 equipped with a damper, the vibration is further damped and dissipated, suppressing the simple harmonic vibration of the spring 23 and generating a damping force. This effectively cancels out the vibration force, improves the buffering and shock absorption effect, effectively reduces the vibration of the air filter body 1, reduces the risk of the air filter body 1 being damaged by vibration, and has a relatively long service life.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
