Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to a stackable air filter. Background Art

[0002] An air filter is a filter, also known as an air filter cartridge, an air cleaner, a filter element, etc. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operating rooms and various precision operating rooms. The air cleaner of an automobile is commonly called an air filter, which is used to filter out impurities such as dust and sand particles suspended in the air, prevent them from entering the engine, and provide clean air for the engine.

[0003] At present, during the use of the air filter for automobiles, generally the air filter is installed inside the air cleaner housing. When the air filter needs to be replaced, although the upper housing can be opened to take out the air filter from inside the air cleaner housing, when the air filter is taken out from inside the air cleaner housing, due to the lack of an effective automatic ejection structure inside the air cleaner housing, it is rather laborious to take out the air filter from inside the air cleaner housing, thus reducing the convenience of disassembling and replacing the air filter. Moreover, during the use of the current air filter, due to the large intake air volume entering the air cleaner housing when the automobile engine is working, under the impact of the air flow, the filter element is prone to concave damage, so that dust and other pollutants enter the engine, causing damage to the engine. Summary of the Utility Model

[0004] The embodiment of the present disclosure relates to a stackable air filter. Through the arrangement of the springs outside the four vertical guide rods, when the air filter needs to be replaced, first the upper housing can be rotated and opened. After the upper housing is rotated and opened, the air filter and the windshield assembly lose the downward pressure. Then, under the elastic force of the springs outside the four vertical guide rods, the air filter and the windshield assembly are ejected upward. At this time, the air filter can be taken off and replaced, thus making it more labor-saving to take out the air filter from inside the air cleaner housing, and improving the convenience of disassembling and replacing the air filter.

[0005] In the first aspect of the present disclosure, a stackable air filter is provided, which specifically includes: an air cleaner housing; a frame-shaped bottom plate is fixedly connected to the bottom of the air cleaner housing, and a lower housing is fixedly connected to the bottom end surface of the frame-shaped bottom plate, and an air inlet pipe is provided at the bottom of the lower housing; the upper part of the air cleaner housing is rotatably connected to an upper housing through a rotating shaft, and an air outlet pipe is provided at the top of the upper housing; three air filters and a windshield assembly are installed inside the air cleaner housing in a stacked manner, and the windshield assembly is located at the bottom of the three air filters.

[0008] In at least some embodiments, a buckle support block is fixedly connected to the middle of the front end face of the upper housing, and two rectangular through holes are symmetrically opened on the upper end face of the buckle support block in the left-right direction; an elastic buckle is slidably connected inside each rectangular through hole, and a spring is installed inside each rectangular through hole.

[0009] In at least some embodiments, when the upper housing is in a closed state on the upper part of the air filter housing, both elastic buckles are clamped to the inner side of the C-shaped clamping block.

[0010] In at least some embodiments, the air filter element includes a frame, a filter element and positioning holes. The filter element is provided inside the frame, and positioning holes are opened at the four corners of the upper end face of the frame.

All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Embodiment 1: Please refer to Figures 1 to 7 :

[0033] The present utility model provides a stackable air filter, including: an air filter housing 1; a frame-shaped bottom plate 103 is fixedly connected to the bottom of the air filter housing 1, and a lower housing 2 is fixedly connected to the bottom end surface of the frame-shaped bottom plate 103, and an air inlet pipe 201 is provided at the bottom of the lower housing 2; the upper part of the air filter housing 1 is rotatably connected to an upper housing 3 through a rotating shaft, and an air outlet pipe 301 is provided at the top of the upper housing 3; three air filters 4 and a windshield assembly 5 are installed inside the air filter housing 1 in a stacked manner, and the windshield assembly 5 is located at the bottom of the three air filters 4; through the stackable air filters 4, the number of air filters 4 can be increased or decreased according to the working environment. For example, when working in an environment with a lot of dust, two air filters 4 can be stacked, and when working in an environment with less dust, only one air filter 4 can be installed, thereby improving the flexibility of the air filter 4 during use.

[0034] A U-shaped clamping block 101 is fixedly connected to the middle side of the upper part of the front end surface of the air filter housing 1, and a sealing rubber ring 102 is provided on the top end surface of the air filter housing 1 to improve the sealing performance after the upper housing 3 is closed.

[0035] Four vertical guide rods 104 are fixedly connected to the upper end surface of the frame-shaped bottom plate 103 inside the air filter housing 1, and a spring is sleeved on the lower end of each vertical guide rod 104, and the lower end of the spring outside each vertical guide rod 104 is fixedly connected to the upper end surface of the frame-shaped bottom plate 103; the free length of the spring outside the four vertical guide rods 104 is equal to the length of each vertical guide rod 104. Through the arrangement of the springs outside the four vertical guide rods 104, when the upper housing 3 is rotated and opened, the air filters 4 and the windshield assembly 5 can be pushed upward under the elastic force of the springs outside the four vertical guide rods 104, thereby improving the convenience of disassembling and replacing the air filters 4.

[0036] A buckle support block 302 is fixedly connected to the middle of the front end face of the upper housing 3, and two rectangular through-holes 303 are symmetrically arranged on the upper end face of the buckle support block 302 from left to right; an elastic buckle 304 is slidably connected to the inside of each rectangular through-hole 303, and a spring is installed inside each rectangular through-hole 303, so that the elastic buckle 304 has good elasticity.

[0037] When the upper housing 3 is in a closed state above the air filter housing 1, both elastic buckles 304 are clamped to the inside of the U-shaped clamping block 101, so that the upper housing 3 realizes an effective limiting function.

[0038] The air filter element 4 includes a frame 401, a filter element 402 and positioning holes 403. The filter element 402 is arranged inside the frame 401, and positioning holes 403 are opened at the four corners of the upper end face of the frame 401. The positioning holes 403 are used for inserting into the vertical guide rods 104 to guide the air filter element 4.

[0039] Embodiment 2, on the basis of Embodiment 1, as Figure 5 and Figure 7 shown, the wind shield assembly 5 includes a wind shield net plate 501, an L-shaped connecting block 502, a wind shield plate 503 and a circular through-hole 504. Circular through-holes 504 are opened at the four corners of the upper end face of the wind shield net plate 501, and the circular through-holes 504 are used for inserting into the vertical guide rods 104; four L-shaped connecting blocks 502 are fixedly connected to the bottom end face of the wind shield net plate 501, and a wind shield plate 503 is fixedly connected to the lower ends of the four L-shaped connecting blocks 502. By providing the wind shield assembly 5, high-speed air flow is prevented from directly impacting the filter element 402, avoiding the phenomenon of depression and damage of the filter element 402.

[0040] The working principle of this embodiment: During use, when the automobile engine is operating, external air enters the intake pipe 201, the lower housing 2 and the air filter housing 1 from bottom to top at a high speed under the action of pressure. Then, under the wind shielding action of the wind shield plate 503 and the wind shield net plate 501, high-speed air flow is prevented from directly impacting the filter element 402, avoiding the phenomenon of depression and damage of the filter element 402. Then, the filter element 402 filters out impurities such as dust and sand in the air and provides clean air for the engine.

[0041] When the air filter element 4 needs to be replaced after long-term use, first pinch the two elastic buckles 304 simultaneously in the opposite directions to separate the two elastic buckles 304 from the inner side of the C-shaped clamping block 101, so that the upper housing 3 loses its limiting function. Then rotate the upper housing 3 to open it. After the upper housing 3 is rotated and opened, the air filter element 4 and the windshield assembly 5 lose the downward pressure, and then under the elastic force of the springs outside the four vertical guide rods 104, the air filter element 4 and the windshield assembly 5 are pushed upward. At this time, the air filter element 4 can be removed and replaced, making it more labor-saving to take out the air filter element 4 from the inside of the air filter housing 1.
