Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, specifically to an air compressor that facilitates the replacement of air filters. Background Technology

[0002] An air compressor is a device used to compress gases. Similar in construction to a water pump, most air compressors are reciprocating piston type, rotary vane, or rotary screw type. Air compressors are frequently used in industrial dust removal. Patent number CN202323314158.X discloses an air compressor with an easy-to-replace air filter element. Through the design of a flip-lock assembly and an automatic filter element pusher mechanism, workers only need to press a button to automatically open the cover and, with the assistance of the automatic filter element pusher, automatically eject the air filter element from the air filter box, achieving one-button replacement and improving replacement efficiency. However, when the air compressor is in use, outside air enters through the gap between the cover and the filter box, is filtered by the filter element, and then enters the air compressor for use. Air passing through the gap can easily seep through the gap between the filter element and the filter box, thus affecting air filtration. Therefore, we propose an air compressor with an easy-to-replace air filter element. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides an air compressor that facilitates the replacement of air filters.

[0004] The technical solution adopted by this utility model to solve its technical problem is an air compressor that facilitates the replacement of air filter elements, including an air compressor body and a grille cylinder. The air compressor body is equipped with a cylinder for support at the air inlet end, and J-shaped grooves are opened on the outer peripheral surface of the cylinder, and there are multiple sets of J-shaped grooves. A ring cover for support is inserted into the top surface of the cylinder, and a locking block that engages with the J-shaped groove is installed on the inner peripheral surface of the ring cover, and there are multiple sets of locking blocks. Magnetic rings that are magnetically connected to each other are installed on the opposite side of the ring cover and the grille cylinder. A filter element body that fits with the ring cover is inserted into the grille cylinder. An air inlet hole that communicates with the filter element body is opened on the inner peripheral surface of the ring cover, and there are multiple sets of air inlet holes.

[0005] A ring plate that fits into the grid cylinder is slidably installed inside the cylinder, and a spring for pushing the ring plate to move is assembled between the ring plate and the cylinder. There are multiple sets of springs, and a shock-absorbing cylinder located between the ring plate and the cylinder is assembled on the inner circumference of the spring. There are multiple sets of shock-absorbing cylinders.

[0006] By adopting the above technical solution, when replacing the air filter element in the air compressor, the ring cover can be rotated directly, causing the ring cover to engage and disengage with the J-shaped groove on the outer periphery of the cylinder. Then, the ring cover inserted at the top of the cylinder can be pulled out, separating the ring cover from the cylinder. Then, the grid cylinder inside the ring cover can be pulled directly, causing the magnetic ring at the top of the grid cylinder to separate from the magnetic ring in the ring cover. Thus, the filter element inside the grid cylinder can be replaced, and the replacement is simple and convenient.

[0007] When replacing the filter element, the filter element can be inserted into the grille cylinder and fit together with the ring cover. Simultaneously, the magnetic ring at the top of the grille cylinder magnetically connects with the magnetic ring at the bottom of the ring cover, ensuring a tight connection between the filter element inside the grille cylinder and the ring cover. This allows outside air to enter the ring cover through the air inlet and smoothly enter the filter element, facilitating air filtration. Meanwhile, the spring inside the cylinder pushes the ring plate, ensuring a stable fit between the ring plate and the grille cylinder and providing thrust to the grille cylinder. This not only improves the stability of the engagement between the ring cover and the cylinder and the J-slot, but also enhances the stability of the magnetic connection between the grille cylinder and the ring cover. This allows the filter element inside the grille cylinder to filter air more stably, facilitating the use of the air compressor. Furthermore, the shock-absorbing cylinder at the bottom of the ring plate works in conjunction with the spring, enabling the ring plate to provide a more stable elastic thrust to the grille cylinder, ensuring more stable operation.

[0008] Specifically, a filter screen cylinder that fits into the filter element body is screwed onto the inner circumference of the ring cover, and a handle for rotation is fitted on the top surface of the ring cover.

[0009] By adopting the above technical solution, the filter screen cylinder screwed into the bottom of the ring cover is connected to the intersection of multiple sets of air inlets inside the ring cover. When outside air passes through the air inlet, it first enters the filter screen cylinder, which facilitates preliminary filtration of the air. The handle on the top of the ring cover makes disassembly and assembly more convenient.

[0010] Specifically, the outer circumferential surface of the ring cover is fitted with a filter ring for protecting the air inlet.

[0011] By adopting the above technical solution, the filter ring can effectively protect the air inlet on the outer periphery of the ring cover, thereby reducing the entry of external debris into the air inlet and enabling the air inlet to guide air more stably.

[0012] Specifically, the cylinder has a cavity inside.

[0013] By adopting the above technical solution, the vacuum cavity inside the cylinder provides a certain noise reduction performance for the inside of the cylinder, allowing the airflow inside the cylinder to flow more smoothly and stably.

[0014] Specifically, the bottom surface of the grid cylinder is fitted with a cross bar for auxiliary support.

[0015] By adopting the above technical solution, the cross bar at the bottom of the grid cylinder can easily support the filter element, so that the filter element can be inserted more stably into the grid cylinder, and the filter element can operate more stably.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of a ring cover, cylinder, J-shaped groove, locking block, grid cylinder, magnetic ring, and filter element, allows for easy and convenient replacement of the air filter element in an air compressor. The ring cover can be rotated to engage and disengage with the locking block and the J-shaped groove on the outer periphery of the cylinder. Then, the ring cover inserted at the top of the cylinder can be removed, separating it from the cylinder. The grid cylinder inside the ring cover can then be pulled, causing the magnetic ring at the top of the grid cylinder to separate from the magnetic ring in the ring cover. This allows for easy replacement of the filter element inside the grid cylinder.

[0018] 2. The technical solution of this application, through the design of the ring plate, spring, shock absorber, and air inlet, allows the filter element to be inserted into the grille cylinder and fitted with the ring cover when the filter element is replaced. Simultaneously, the magnetic ring at the top of the grille cylinder magnetically connects with the magnetic ring at the bottom of the ring cover, ensuring a tight connection between the filter element inside the grille cylinder and the ring cover. This allows outside air to enter the ring cover through the air inlet and stably enter the filter element, facilitating air filtration. The spring inside the cylinder pushes the ring plate, ensuring a stable fit between the ring plate and the grille cylinder and providing thrust to the grille cylinder. This not only improves the stability of the engagement between the ring cover and the cylinder and the J-shaped groove but also enhances the stability of the magnetic connection between the grille cylinder and the ring cover. This allows the filter element inside the grille cylinder to filter air more stably, facilitating the use of the air compressor. Furthermore, the shock absorber at the bottom of the ring plate works in conjunction with the spring, enabling the ring plate to provide a more stable elastic thrust to the grille cylinder, ensuring more stable operation.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3 This utility model provides a technical solution: an air compressor that facilitates air filter replacement, comprising an air compressor body 1 and a grille cylinder 8. The air compressor body 1 has a cylinder 2 for support at its air inlet end, and the outer circumferential surface of the cylinder 2 has J-shaped grooves 4, with multiple sets of J-shaped grooves 4. A ring cover 3 for support is inserted into the top surface of the cylinder 2, and the inner circumferential surface of the ring cover 3 is equipped with locking blocks 5 that engage with the J-shaped grooves 4, with multiple sets of locking blocks 5. The side of the ring cover 3 opposite to the grille cylinder 8 is equipped with... The magnetic rings 9 are magnetically connected to each other, and the filter element 10 that fits with the ring cover 3 is inserted into the grid cylinder 8. The inner circumference of the ring cover 3 is provided with an air inlet 11 that communicates with the filter element 10, and there are multiple sets of air inlets 11. The ring plate 7 that fits with the grid cylinder 8 is slidably installed in the cylinder 2, and a spring 6 for pushing the ring plate 7 to move is assembled between the ring plate 7 and the cylinder 2, and there are multiple sets of springs 6. The inner circumference of the spring 6 is equipped with a shock absorber 15 located between the ring plate 7 and the cylinder 2, and there are multiple sets of shock absorber 15.

[0026] When replacing the air filter in the air compressor, the ring cover 3 can be rotated directly to make the ring cover 3 drive the locking block 5 to engage and disengage with the J-shaped groove 4 on the outer periphery of the cylinder 2. Then, the ring cover 3 inserted at the top of the cylinder 2 can be pulled out to separate the ring cover 3 from the cylinder 2. Then, the grid cylinder 8 inside the ring cover 3 can be pulled directly to separate the magnetic ring 9 at the top of the grid cylinder 8 from the magnetic ring 9 in the ring cover 3. Thus, the filter element 10 inside the grid cylinder 8 can be replaced, and the replacement is simple and convenient.

[0027] When replacing the filter element 10, the filter element 10 can be inserted into the grille cylinder 8 and fit together with the ring cover 3. Simultaneously, the magnetic ring 9 at the top of the grille cylinder 8 can be magnetically connected to the magnetic ring 9 at the bottom of the ring cover 3, ensuring a tight connection between the filter element 10 inside the grille cylinder 8 and the ring cover 3. This allows outside air to enter the ring cover 3 through the air inlet 11 and stably enter the filter element 10, facilitating air filtration. Meanwhile, the spring 6 inside the cylinder 2 can easily push the ring plate 7, causing the ring plate 7... The stable engagement with the grille cylinder 8 and the provision of thrust to the grille cylinder 8 not only improves the stability of the engagement between the locking block 5 and the J-shaped groove 4 between the ring cover 3 and the cylinder 2, but also improves the stability of the magnetic connection between the grille cylinder 8 and the ring cover 3. This allows the filter element 10 inside the grille cylinder 8 to filter the air more stably, making it convenient for the air compressor to use. Furthermore, the shock-absorbing cylinder 15 at the bottom of the ring plate 7 can cooperate with the spring 6, allowing the ring plate 7 to provide elastic thrust to the grille cylinder 8 more stably, enabling it to operate more stably.

[0028] like Figure 1 and Figure 2 As shown, a filter screen cylinder 12 that fits into the filter element body 10 is screwed onto the inner circumference of the ring cover 3, and a handle 17 for rotation is fitted on the top surface of the ring cover 3.

[0029] When in use, the filter cylinder 12 screwed into the bottom of the ring cover 3 is connected to the intersection of the multiple sets of air inlets 11 inside the ring cover 3. When outside air passes through the air inlets 11, it will first enter the filter cylinder 12, and the filter cylinder 12 facilitates the initial filtration of the air. The handle 17 on the top of the ring cover 3 makes disassembly and assembly more convenient.

[0030] like Figure 1 and Figure 2 As shown, a filter ring 13 for protecting the air inlet 11 is fitted on the outer peripheral surface of the ring cover 3.

[0031] When in use, the filter ring 13 can protect the air inlet 11 on the outer periphery of the ring cover 3, which can reduce the entry of external debris into the air inlet 11 and enable the air inlet 11 to guide the air more stably.

[0032] like Figure 2 As shown, a cavity 14 is provided inside the cylinder 2.

[0033] When in use, the vacuum cavity 14 inside the cylinder 2 provides a certain noise reduction performance for the inside of the cylinder 2, so that the airflow inside the cylinder 2 can flow more smoothly and stably.

[0034] like Figure 2 As shown, the bottom surface of the grid tube 8 is fitted with a cross bar 16 for auxiliary support.

[0035] When in use, the cross bar 16 at the bottom of the grid cylinder 8 provides convenient support for the filter element 10, allowing the filter element 10 to be inserted more stably into the grid cylinder 8 and enabling the filter element 10 to operate more stably.

[0036] The working principle and usage process of this utility model are as follows: In use, first install the corresponding structural components in the appropriate positions. When replacing the air filter element in the air compressor, the ring cover 3 can be directly rotated, causing the ring cover 3 to engage and disengage with the locking block 5 and the J-shaped groove 4 on the outer periphery of the cylinder 2. Then, the ring cover 3 inserted at the top of the cylinder 2 can be pulled out, separating the ring cover 3 from the cylinder 2. Then, the grid cylinder 8 inside the ring cover 3 can be directly pulled, causing the magnetic ring 9 at the top of the grid cylinder 8 to separate from the magnetic ring 9 in the ring cover 3, thus... The filter element 10 inside the grille cylinder 8 can be replaced easily and conveniently. During replacement, the filter element 10 can be inserted into the grille cylinder 8 and fit snugly against the ring cover 3. Simultaneously, the magnetic ring 9 at the top of the grille cylinder 8 magnetically connects with the magnetic ring 9 at the bottom of the ring cover 3, ensuring a tight connection between the filter element 10 inside the grille cylinder 8 and the ring cover 3. This allows outside air to reliably enter the filter element 10 through the air inlet 11 into the ring cover 3, facilitating air filtration. Meanwhile, the spring 6 inside the cylinder 2 facilitates the pushing of the ring plate 7, allowing the ring plate 7 to stably engage with the grille cylinder 8 and provide thrust for the grille cylinder 8. This not only improves the stability of the engagement between the locking block 5 and the J-shaped groove 4 between the ring cover 3 and the cylinder 2, but also enhances the stability of the magnetic connection between the grille cylinder 8 and the ring cover 3. Furthermore, it allows the filter element 10 inside the grille cylinder 8 to filter air more stably, facilitating the use of the air compressor. Additionally, the shock-absorbing cylinder 15 at the bottom of the ring plate 7 cooperates with the spring 6, enabling the ring plate 7 to more stably support the grille cylinder 8. It provides elastic thrust, enabling it to operate more stably. When the air compressor is operating, outside air can easily pass through the filter ring 13 and enter the multiple sets of air inlets 11 inside the ring cover 3. It can also easily pass through the multiple sets of air inlets 11 and gather at the outlet on the inner circumference of the ring cover 3. Then the air enters the filter cylinder 12 and is filtered by the filter cylinder 12 before being discharged. This allows it to come into contact with the filter element 10, enabling the filter element 10 to continue filtering it. Subsequently, the air passes through the grille cylinder 8 and the ring plate 7 and enters the air compressor body 1, facilitating the use of the air compressor.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
