[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figures 1-4 This utility model provides a high-strength filtration type shock-absorbing and low-noise air filter, which includes a connecting pipe 1. An air inlet chamber 2 and an air outlet chamber 3 are respectively attached to both ends of the connecting pipe 1. An air inlet pipe 4 and an air outlet pipe 5 are respectively fixedly connected to the ends of the air inlet chamber 2 and the air outlet chamber 3 opposite to the connecting pipe 1. A first filter element 12 and a second filter element 13 are respectively provided inside the air outlet chamber 3 and the air inlet chamber 2. The first filter element 12 and the second filter element 13 are filter materials with different pore sizes, which can effectively filter impurities in the air.

[0025] The bottom of the air outlet chamber 3 is equipped with a shock-absorbing assembly, which includes a base plate 8, second shock-absorbing pads 10 fixedly connected to the bottom of both ends of the base plate 8, and a first shock-absorbing pad 9 fixedly connected to the bottom of the base plate 8. The top surface of the first shock-absorbing pad 9 is in contact with the bottom of the air outlet chamber 3. An n-shaped connecting frame 11 is also fixedly connected to the top of the base plate 8, and the top of the connecting frame 11 is in contact with the top of the air outlet chamber 3. When the air outlet chamber 3 is fixed by the base plate 8 and the connecting frame 11, the vibration generated by the air filter is effectively absorbed and mitigated by the action of the first shock-absorbing pad 9 and the second shock-absorbing pad 10. When the air filter or its connected components vibrate due to machine operation, external impact, etc., the shock-absorbing pads can reduce the transmission and diffusion of vibration, which helps to protect the air filter and its connected components from damage. At the same time, it also helps to reduce noise caused by vibration, achieving good vibration reduction and low noise effect.

[0026] A corrugated hose 6 is fixedly connected to the end of the air outlet pipe 5 away from the air outlet chamber 3. The air outlet pipe 5 is connected to external equipment through the corrugated hose 6, which has better flexibility and elasticity compared to rigid pipes. When external equipment vibrates, the corrugated hose 6 can absorb and mitigate these vibrations, thereby reducing the impact and damage to the air filter.

[0027] The bottom of the intake chamber 2 is also equipped with a shock-absorbing component. The bottom plate 8, the first shock-absorbing pad 9 and the second shock-absorbing pad 10 at the bottom of the intake chamber 2 can better support the intake chamber 2 and enhance the shock absorption effect of the air filter.

[0028] Annular plates 14 are fixedly connected inside the connecting pipe 1, the air inlet chamber 2, and the air outlet chamber 3. The first filter element 12 and the second filter element 13 are respectively clamped between every two adjacent annular plates 14. Inside the air inlet chamber 2 and the air outlet chamber 3, the first filter element 12 and the second filter element 13 are clamped and fixed by multiple annular plates 14 to ensure the stability and filtration effect of the first filter element 12 and the second filter element 13. Four L-shaped connecting plates 15 are fixedly and symmetrically connected at equal intervals on the outer sides of the opposite end of the air inlet chamber 2 and the air outlet chamber 3. Four connecting components connected to the corresponding connecting plates 15 are symmetrically and equidistantly provided on the outer sides of both ends of the connecting pipe 1. The connection between the connecting pipe 1 and the air inlet chamber 2 and the air outlet chamber 3 is detachable through the connecting components, making disassembly and assembly convenient.

[0029] The connecting assembly includes a mounting plate 19 fixedly connected to the outside of the connecting pipe 1, a movable frame 16 hinged to the top of the mounting plate 19, a lead screw 17 threadedly connected to the inside of the movable frame 16, and a knob 18 fixedly connected to the end of the lead screw 17. The end of the lead screw 17 away from the knob 18 is fitted with the folded edge of the connecting plate 15. After the air inlet chamber 2 or the air outlet chamber 3 is fitted with the end of the connecting pipe 1, the extension and retraction of the lead screw 17 can be adjusted by rotating the knob 18 after flipping the movable frame 16. This allows the lead screw 17 to fit with the folded edge of the connecting plate 15, achieving a tight connection between the air inlet chamber 2, the air outlet chamber 3, and the connecting pipe 1. At the same time, the movable connection facilitates the disassembly of the air inlet chamber 2 and the connecting pipe 1, making it convenient to clean or replace the first filter element 12 and the second filter element 13.

[0030] Sealing gaskets 7 are fixedly connected to one end of the air inlet chamber 2 near the connecting pipe 1, one end of the air outlet chamber 3 near the connecting pipe 1, and both ends of the connecting pipe 1. The sealing gaskets 7 ensure the airflow is sealed and prevent abnormal airflow noise that may be generated from air leakage from the connection. Sound insulation cotton is provided on the outer surface of the connecting pipe 1, the air inlet chamber 2, and the air outlet chamber 3. The sound insulation cotton can effectively reduce the noise generated by the airflow inside the connecting pipe 1, the air inlet chamber 2, and the air outlet chamber 3.

[0031] Working principle: After the air inlet chamber 2 or the air outlet chamber 3 is attached to the end of the connecting pipe 1, the movable frame 16 is flipped over and the extension and retraction of the lead screw 17 can be adjusted by rotating the knob 18. This allows the lead screw 17 to be attached to the folded edge of the connecting plate 15, achieving a tight connection between the air inlet chamber 2, the air outlet chamber 3 and the connecting pipe 1. At the same time, the movable connection method facilitates the disassembly of the air inlet chamber 2 and the connecting pipe 1, making it convenient to clean or replace the first filter element 12 and the second filter element 13.

[0032] When the air outlet chamber 3 is fixed by the base plate 8 and the connecting frame 11, the vibration generated by the air filter is effectively absorbed and mitigated by the first damping pad 9 and the second damping pad 10. When the air filter or its connected components vibrate due to machine operation, external impact, etc., the damping pads can reduce the transmission and diffusion of vibration, help protect the air filter and its connected components from damage, and also help reduce noise caused by vibration, achieving good vibration reduction and low noise effect;

[0033] The air outlet pipe 5 connects to external equipment via a corrugated hose 6, which offers better flexibility and elasticity compared to rigid pipes. When external equipment vibrates, the corrugated hose 6 absorbs and mitigates these vibrations, thereby reducing the impact and damage to the air filter.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
