A convenient-to-install cyclone air filter

Abstract

This utility model provides a conveniently installed cyclone air filter, including a cylinder, an exhaust pipe, an air inlet, and an air inlet pipe. The exhaust pipe is fixedly connected to the top of the cylinder, and the air inlet is fixedly connected to one side of the cylinder. This utility model relates to the technical field of cyclone air filters. By setting a positioning mechanism, when the air inlet pipe needs to be installed, pulling the pull ring to the right engages with the positioning mechanism, causing the positioning rod to retract into the housing and align with the snap-fit ​​block and snap-fit ​​groove. Pushing the air inlet pipe to the left moves the second connecting ring and the housing, allowing the snap-fit ​​block to enter the corresponding snap-fit ​​groove. Releasing the pull ring then causes the tension spring to move the linkage block to the left. Repeating the above steps, the movable block eventually moves the positioning rod away from the tension spring, allowing the positioning rod to enter the corresponding positioning hole. This completes the fixing of the housing and the snap-fit ​​block, thus allowing the air inlet pipe to be installed on the air inlet, facilitating installation.

Description

Technical Field

[0001] This utility model relates to the technical field of cyclone air filters, specifically a cyclone air filter that is easy to install. Background Technology

[0002] A cyclone air filter is a device used to remove dust from the air. It consists of a cylinder, an inlet pipe, an outlet pipe, and a discharge pipe. Dust-laden gas is drawn into the cyclone air filter by a fan and rotates downwards along the inside of the cylinder. The rotational inertia generates centrifugal force, which separates the particulate matter in the gas when it reaches the bottom. The particulate matter then enters the dust hopper through the discharge pipe, and the gas is discharged through the outlet pipe, thus achieving the effect of dust removal.

[0003] However, the above-mentioned device still has the following problems during implementation:

[0004] When using a cyclone air filter, the air inlet pipe needs to be installed at the air inlet. During installation, it needs to be fixed manually with multiple bolts, which is very inconvenient, requires a lot of tools, and is time-consuming and labor-intensive.

[0005] To address this issue, we propose a conveniently installed cyclone air filter. Utility Model Content

[0006] The purpose of this invention is to provide a cyclone air filter that is easy to install, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A conveniently installed cyclone air filter includes a cylinder, an exhaust pipe, an air inlet, and an air inlet pipe. The exhaust pipe is fixedly connected to the top of the cylinder, and the air inlet is fixedly connected to one side of the cylinder. The air inlet pipe is located on one side of the air inlet. A first mating ring is fixedly connected to one side of the air inlet, and a second mating ring is fixedly connected to one side of the air inlet pipe. Positioning blocks are fixedly connected to both sides of the first mating ring, and two snap-fit ​​blocks are fixedly connected to one side of each positioning block. A housing is fixedly connected to both sides of the second mating ring, and a snap-fit ​​groove for cooperating with the snap-fit ​​blocks is provided on one side of the housing. A positioning mechanism is provided inside the housing.

[0009] The positioning mechanism includes a linkage block disposed inside the housing. Movable blocks are disposed on both sides of the linkage block. The linkage block and the movable blocks are connected by a connecting rod. Two positioning rods are fixedly connected to the side of the two movable blocks that are far apart from each other. The side of the positioning rod that is far away from the movable block extends into the interior of the snap-fit ​​groove. A positioning hole is provided on one side of the snap-fit ​​block for use with the positioning rod.

[0010] A stabilizing mechanism is fixedly installed on one side of the first docking ring and can support the air inlet pipe.

[0011] Preferably, the stabilizing mechanism includes a support tube fixedly connected to one side of the first docking ring, one side of the support tube extending into the interior of the second docking ring, a sealing ring fixedly connected to the inner wall of the second docking ring, and two arc-shaped embedding blocks fixedly connected to the top and bottom of the support tube, and an embedding groove for cooperating with the arc-shaped embedding blocks is provided on the inner wall of the sealing ring.

[0012] Preferably, the sealing ring is made of rubber, and its inner wall is in contact with the surface of the support tube.

[0013] Preferably, a tension spring is fixedly connected to one side of the linkage block, and one end of the tension spring is fixedly connected to the inner wall of the housing.

[0014] Preferably, a traction rod is fixedly connected to the side of the linkage block away from the tension spring, and one end of the traction rod extends through to the outside of the housing and is fixedly connected to a pull ring.

[0015] Preferably, sliding blocks are fixedly connected to both sides of the movable block, and the inner wall of the sliding block is provided with a sliding groove for use with the sliding block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, by setting a positioning mechanism, allows for easy installation of the air inlet pipe. When the pull ring is pulled to the right, it works in conjunction with the positioning mechanism to retract the positioning rod into the housing, aligning it with the position of the snap-fit ​​block and the snap-fit ​​groove. Pushing the air inlet pipe to the left causes the air inlet pipe to move the second connecting ring and the housing, allowing the snap-fit ​​block to enter the corresponding snap-fit ​​groove. After releasing the pull ring, the tension generated by the tension spring causes the linkage block to move to the left. The reverse of the above steps results in the movable block moving the positioning rod away from the tension spring, allowing the positioning rod to enter the corresponding positioning hole. This completes the fixing of the housing and the snap-fit ​​block, enabling the air inlet pipe to be installed on the air inlet, thus facilitating installation.

[0018] 2. By setting up a stabilizing mechanism, this utility model can push the air inlet pipe and the second docking ring to the left, while the support pipe enters the inner wall of the second docking ring. At the same time, the arc-shaped embedding block also enters the interior of the embedding groove. The surface of the support pipe will contact the inner wall of the sealing ring, thereby effectively improving the sealing performance of the connection. With the entry of the support pipe, the second docking ring and the air inlet pipe can also be supported, thereby improving the stability of the air inlet pipe after installation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution:

[0027] Example 1:

[0028] A conveniently installed cyclone air filter includes a cylinder 1, an exhaust pipe 2, an air inlet 3, and an air inlet pipe 4. The exhaust pipe 2 is fixedly connected to the top of the cylinder 1, the air inlet 3 is fixedly connected to one side of the cylinder 1, and the air inlet pipe 4 is located on one side of the air inlet 3. A first docking ring 5 is fixedly connected to one side of the air inlet 3, and a second docking ring 6 is also fixedly connected to one side of the air inlet pipe 4. Positioning blocks 7 are fixedly connected to both sides of the first docking ring 5, and two snap-fit ​​blocks 8 are fixedly connected to one side of the positioning blocks 7. A housing 9 is fixedly connected to both sides of the second docking ring 6. A snap-fit ​​groove 10 that cooperates with the snap-fit ​​blocks 8 is opened on one side of the housing 9, and a positioning mechanism is provided inside the housing 9.

[0029] The positioning mechanism includes a linkage block 11 disposed inside the housing 9. Movable blocks 12 are provided on both sides of the linkage block 11. The linkage block 11 and the movable blocks 12 are connected by a connecting rod 13. Two positioning rods 14 are fixedly connected to the side of the two movable blocks 12 that are far away from each other. The side of the positioning rod 14 that is far away from the movable blocks 12 extends into the interior of the snap-fit ​​groove 10. A positioning hole 15 is provided on one side of the snap-fit ​​block 8 to cooperate with the positioning rod 14.

[0030] The stabilizing mechanism is fixedly installed on one side of the first docking ring 5 and can support the air inlet pipe 4.

[0031] In this embodiment, considering that the cyclone air filter requires the air inlet pipe 4 to be installed at the air inlet 3 during use, and that installation requires manual fixing with multiple bolts, which is inconvenient, requires numerous tools, and is time-consuming and labor-intensive, a positioning mechanism is provided to allow for easy installation of the air inlet pipe 4. Figure 2 , Figure 3 and Figure 4 As shown, by pulling the pull ring 22 to the right, the pull ring 22 drives the traction rod 21 and the linkage block 11 to move to the right. The linkage block 11 drives the connecting rod 13 to move, and the connecting rod 13 rotates and adjusts around the hinge. At the same time, it pulls the two movable blocks 12 to move closer to each other. The movable blocks 12 then drive the positioning rod 14 to retract into the housing 9, aligning it with the position of the snap-fit ​​block 8 and the snap-fit ​​groove 10. Pushing the air inlet pipe 4 to the left, the air inlet pipe 4 drives the second docking ring 6 and the housing 9 to move, so that the snap-fit ​​block 8 enters the corresponding snap-fit ​​groove 10. Then, the pull ring 22 is released, and the tension generated by the tension spring 20 drives the linkage block 11 to move to the left. The steps are reversed. Finally, the movable block 12 drives the positioning rod 14 to move away from the tension spring 20, so that the positioning rod 14 enters the corresponding positioning hole 15. This completes the fixing of the housing 9 and the snap-fit ​​block 8, and then the air inlet pipe 4 is installed on the air inlet 3, which facilitates installation.

[0032] A tension spring 20 is fixedly connected to one side of the linkage block 11, and one end of the tension spring 20 is fixedly connected to the inner wall of the housing 9.

[0033] In this embodiment, by setting a tension spring 20, when the pull ring 22 is released, the tension generated by the tension spring 20 can drive the linkage block 11, the connecting rod 13, the movable block 12 and the positioning rod 14 to move, thereby achieving the function of resetting.

[0034] A traction rod 21 is fixedly connected to the side of the linkage block 11 away from the tension spring 20. One end of the traction rod 21 extends through to the outside of the housing 9 and is fixedly connected to a pull ring 22.

[0035] In this embodiment, by setting a traction rod 21 and a pull ring 22, the traction rod 21 and the linkage block 11 can be moved by pulling the pull ring 22. Through the cooperation between the linkage block 11, the connecting rod 13 and the movable block 12, the positioning rod 14 is retracted into the housing 9, which plays a driving role.

[0036] Both sides of the movable block 12 are fixedly connected to sliding blocks 23, and the inner wall of the sliding block 23 is provided with a sliding groove 24 that cooperates with the sliding block 23.

[0037] In this embodiment, by setting the sliding block 23 and the sliding groove 24, when the connecting rod 13 drives the movable block 12 to move, it can be restricted to move only along the trajectory of the sliding block 23 and the sliding groove 24, thereby limiting the movement trajectory.

[0038] Example 2:

[0039] The stabilizing mechanism includes a support tube 16 fixedly connected to one side of the first docking ring 5. One side of the support tube 16 extends into the interior of the second docking ring 6. A sealing ring 17 is fixedly connected to the inner wall of the second docking ring 6. Two arc-shaped inserts 18 are fixedly connected to the top and bottom of the support tube 16. An insert groove 19 is provided on the inner wall of the sealing ring 17 to cooperate with the arc-shaped inserts 18.

[0040] In this embodiment, a stabilizing mechanism is provided, as referenced. Figure 2 As shown, while pushing the air inlet pipe 4 and the second docking ring 6 to the left, the support pipe 16 will enter the inner wall of the second docking ring 6, and the arc-shaped embedding block 18 will also enter the interior of the embedding groove 19. The surface of the support pipe 16 will contact the inner wall of the sealing ring 17, thereby effectively improving the sealing performance of the connection. With the entry of the support pipe 16, it can also support the second docking ring 6 and the air inlet pipe 4, thereby improving the stability of the air inlet pipe 4 after installation.

[0041] The sealing ring 17 is made of rubber, and its inner wall is in contact with the surface of the support tube 16.

[0042] In this embodiment, by making the sealing ring 17 a rubber material, the surface of the support tube 16 can be in closer contact with the inner wall of the sealing ring 17, effectively improving the sealing effect.

[0043] Working principle: When it is necessary to install air inlet duct 4, refer to... Figure 2 , Figure 3 and Figure 4As shown, by pulling the pull ring 22 to the right, the pull ring 22 drives the traction rod 21 and the linkage block 11 to move to the right. The linkage block 11 will drive the connecting rod 13 to move. The connecting rod 13 will rotate and adjust around the hinge. At the same time, it pulls the two movable blocks 12 to move closer to each other. The movable blocks 12 will drive the positioning rod 14 to retract into the housing 9 and align with the position of the snap-fit ​​block 8 and the snap-fit ​​groove 10. Push the air inlet pipe 4 to the left. The air inlet pipe 4 will drive the second docking ring 6 and the housing 9 to move, so that the snap-fit ​​block 8 enters the corresponding snap-fit ​​groove 10. Then, release the pull ring 22. The tension generated by the tension spring 20 will drive the linkage block 11 to move to the left. The steps are reversed. Finally, the movable block 12 will drive the positioning rod 14 to move away from the tension spring 20, so that the positioning rod 14 enters the corresponding positioning hole 15. This completes the fixing of the housing 9 and the snap-fit ​​block 8, and then the air inlet pipe 4 is installed on the air inlet 3, which facilitates the installation.

[0044] As the air inlet pipe 4 and the second docking ring 6 are pushed to the left, the support pipe 16 will enter the inner wall of the second docking ring 6, and the arc-shaped embedding block 18 will also enter the interior of the embedding groove 19. The surface of the support pipe 16 will contact the inner wall of the sealing ring 17, thereby effectively improving the sealing of the connection. With the entry of the support pipe 16, the second docking ring 6 and the air inlet pipe 4 can also be supported, thereby improving the stability of the air inlet pipe 4 after installation.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
