In order to facilitate the description, the sectional view of the device structure is partially enlarged without the general proportion, and the schematic diagram is only an example, which should not limit the scope of the application protection. In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual production.

[0030] Please refer to the accompanying Figures 1-5 The application provides a multi-stage filtering energy-efficient air filter, which comprises a cylinder body 1, a first filter plate 3, a fixed table 6, a second filter plate 7, a third filter plate 8 and a gas conveying pipe 9. The top of the cylinder body 1 is respectively provided with an air inlet 2 and an air outlet 5. The inside of the cylinder body 1 has a circulation path for filtering air. The air enters from the air inlet 2, is filtered and then discharged from the air outlet 5. An air filter groove 4 is located in the middle of the first filter plate 3.

[0031] The air filter groove 4 is filled with liquid.

[0032] The first filter plate 3 and the air filter groove 4 are located in the inside of the cylinder body 1. The air filter groove 4 is located above the fixed table 6. The second filter plate 7 is located below the fixed table 6. The third filter plate 8 is located below the second filter plate 7. The gas conveying pipe 9 is located at the central position in the inside of the cylinder body 1. The tail end of the gas conveying pipe 9 is located below the third filter plate 8. The top position of the gas conveying pipe 9 extends vertically upward and passes through the third filter plate 8, the second filter plate 7, the fixed table 6, the first filter plate 3 and the air filter groove 4. The end of the gas conveying pipe 9 is located in the inside of the air filter groove 4.

[0033] Based on the first filter plate 3 and the second filter plate 7 in the above structure, according to the characteristics of the air to be filtered, any one of polyester fiber, synthetic fiber, glass fiber or activated carbon material can be used, or they can be used in combination, which can achieve better removal of odor and harmful gas. The above material structure has good moisture resistance, high temperature resistance and stability, which prolongs the efficient filtering life.

[0034] Please refer to the accompanying Figures 2-3As shown, the first filter plate 3 is formed by multiple inclined filter plates, and the filter plates surround the air filter groove 4 to form a multi-layer filtering structure. The middle of the fixed table 6 is raised, and the air filter groove 4 is fixed at the middle of the fixed table 6. The inclined surface of the fixed table 6 is provided with a first filter hole 601, and the third filter plate 8 is provided with a second filter hole 801 for air circulation.

[0035] Please refer to the accompanying drawings Figure 3 With Figure 5 As shown, the second filter plate 7 is provided with multiple annular filter cavities 701 distributed at equal intervals along 9. The annular filter cavities 701 are recessed downward to form V-shaped cavities.

[0036] Specifically, the bottom of the fixed table 6 is raised upward, and the filter cavity of the second filter plate 7 is downwardly opened. There is a sufficient cavity for air filtration between the second filter plate 7 and the fixed table 6. Moreover, the V-shaped cavity formed by the downward recess of the second filter plate 7 enlarges the filtering area. The combination of the fixed table 6 and the second filter plate 7 prolongs the filtering path, which helps the air filtration effect.

[0037] Please refer to the accompanying drawings Figure 4 As shown, the gas conveying pipe 9 is provided with a first valve 10 and a second valve 11 distributed upward and downward. The second valve 11 includes a valve ball 111, a spring 112, and a valve plate 113. The spring 112 abuts against the valve ball 111 and tightly presses the valve ball 111 on the pipe neck in the gas conveying pipe 9. The gas in the cylinder body 1 passes through the gas conveying pipe 9 and the two valves inside the gas conveying pipe 9, and is discharged into the inside of the air filter groove 4. The second valve 11 is arranged close to the port of the gas conveying pipe 9. The first valve 10 has the same structure as the second valve 11.

[0038] More specifically, two valve bodies are arranged in the gas conveying pipe 9. The second valve 11 can avoid liquid leakage in the air filter groove 4. The second valve 11 is installed in cooperation with the first valve 10. When the air pressure in the cylinder body 1 gradually decreases, the second valve 11 and the first valve 10 are closed one by one to isolate the liquid from flowing back into the inside of the cylinder body 1, thereby providing double protection.

[0039] Please refer to the accompanying drawings Figures 4-5 As shown, the fixed table 6, the first filter plate 3, and the air filter groove 4 are provided with a sealing member 12 at the penetrating position of the gas conveying pipe 9. The top of the gas conveying pipe 9 is provided with a filter head 13.

[0040] Based on the above structure, the air to be filtered enters the inside of the cylinder body 1 from the air inlet 2, under the action of air pressure, the gas is preliminarily filtered through the first filter plate 3, and then enters the inner cavity of the fixed table 6 through the first filter hole 601, the gas is twice filtered through the second filter plate 7, and finally the gas is discharged into the air filter tank 4 through the gas pipe 9. Since the air filter tank 4 contains liquid, when the air wants to be discharged from the cylinder body 1, the gas is filtered by the liquid for the last time, the inside of the cylinder body 1 forms a circulating path of filtered air, and multi-stage filtering helps to improve the quality of air filtration. When dealing with dust or smoke filtration, it can be filtered more pure, and in the last filtering, the particulate impurities in the air will be adsorbed by water molecules when passing through the water layer, and part of the impurities will therefore settle or be attached to the water surface after being wetted. The air is dispersed into countless small bubbles by the filter head 13, which can increase the contact area between the air and the water, thereby further improving the filtering effect.

[0041] The working principle of the utility model is:

[0042] Through the combination of multi-stage filtering (the first filter plate 3, the second filter plate 7, the third filter plate 8) and the liquid in the air filter tank 4, efficient purification of air is realized. And through the design of the internal filtering structure (such as V-shaped chamber, inclined filter plate, filter head dispersed bubbles, etc.), the filtering path is optimized, the contact time of air and filtering material is prolonged, and the filtering effect is significantly improved. At the same time, the double valve design in the gas pipe effectively prevents liquid from flowing backward, ensures the stability and reliability of the filter, and is suitable for treating complex pollutants such as dust and smoke, and can provide more pure air purification effect.

[0043] The above is only the preferred embodiment of the utility model, it should be pointed out that for ordinary skilled person in the art, without departing from the principle of the utility model, a number of improvements and refinements can be made, which should be regarded as the protection scope of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the art, unless otherwise specified and limited.
