Description

Technical Field

[0001] This utility model relates to the field of axial flow fan technology, and more specifically, to a low-noise axial flow fan that is easy to clean. Background Technology

[0002] An axial flow fan is one in which the airflow is in the same direction as the fan blades' axis, such as an electric fan or the outdoor unit fan of an air conditioner. It's called an "axial flow" fan because the gas flows parallel to the fan's axis. Axial flow fans are typically used in applications requiring high flow rates but low pressure.

[0003] A search revealed a novel axial flow fan in the prior art, with patent publication number CN213450959U. The specification states that the mesh plate is symmetrically provided with first protrusions, and the inner wall of the housing is symmetrically provided with first grooves corresponding to the first protrusions, which facilitates the installation and disassembly of the mesh plate.

[0004] However, in actual cleaning, after the mesh panels are removed, dust still adheres to them. At this point, a cleaning brush can be used to clean the inside and outside. If stubborn stains are present, it will take more time to clean them, which not only increases the labor intensity for workers but also reduces the cleaning efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a low-noise axial flow fan that is easy to clean the mesh, so as to solve the problem that in the prior art, if there are stubborn stains on the mesh plate, more time is required to clean it, which not only makes the labor intensity of workers higher, but also makes the cleaning efficiency lower.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a low-noise axial flow fan that facilitates mesh cleaning, comprising a fan body and two mesh plates. The adjacent sides of the two mesh plates are respectively attached to the front and rear sides of the fan body. Two connecting grooves are opened inside the front and rear sides of the fan body. Connecting plates are slidably connected inside the connecting grooves. The connecting plates are fixedly connected to the mesh plates. Multiple arc-shaped grooves are opened on the opposite sides of the connecting plates on the left and right sides. A slot is opened on one side of the inner wall of the connecting groove. An arc-shaped block is engaged inside the slot. A locking block is fixedly connected on the opposite sides of the arc-shaped block on the left and right sides. The locking block is engaged inside the connecting plate.

[0007] The inner wall of the connecting groove has an installation groove on the other side. The end of the locking block away from the arc-shaped block is fixedly connected to an installation block. The end of the installation block away from the locking block is fixedly connected to a pull rope. An elastic element is sleeved on the outside of the pull rope. A rotating rod is fixedly connected to the side of the pull rope away from the installation block.

[0008] Among them, elastic elements are provided on the adjacent sides of the two grid plates, and the front and rear ends of the fan body are fixedly connected with insert rings, and rubber rings are fixedly connected to the outside of the insert rings.

[0009] The arc-shaped block slides with the connecting plate and is slidably connected inside the arc-shaped groove.

[0010] The card block and the arc-shaped block are both slidably connected inside the mounting groove, and the mounting block is slidably connected inside the mounting groove.

[0011] The pull rope is slidably connected inside the mounting groove, and the rotating rod is rotatably connected inside the top of the fan body.

[0012] One end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the mounting block.

[0013] The insert ring is inserted into the inside of the sealing groove, and the rubber ring fits against the inside of the sealing groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, the connecting blocks on the grid plate are snapped together using clips, making it easy to install and remove the grid plate. During the disassembly and cleaning process, the connecting plate is tapped with an arc-shaped block, causing the grid plate to vibrate. This causes some of the dust on the outside of the grid plate to fall off and loosens stubborn stains, achieving a pre-cleaning effect. This not only reduces the labor intensity of workers but also increases the cleaning efficiency. Attached Figure Description

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a low-noise axial flow fan with easy-to-clean mesh, comprising a fan body 1 and two mesh plates 2. The adjacent sides of the two mesh plates 2 are respectively attached to the front and rear sides of the fan body 1, resulting in good sealing between the fan body 1 and the mesh plates 2. Two connecting grooves 3 are provided inside the front and rear sides of the fan body 1. Connecting plates 4 are slidably connected inside the connecting grooves 3, providing installation space for the connecting plates 4. The connecting plates 4 are fixedly connected to the mesh plates 2. The opposite sides of the connecting plates 4 on the left and right sides are respectively... Multiple arc-shaped grooves 5 are provided. A slot 6 is provided on one side of the inner wall of the connecting groove 3. An arc-shaped block 7 is engaged inside the slot 6. The arc-shaped block 7 slides with the connecting plate 4, allowing the arc-shaped block 7 to slide inside and outside the connecting plate 4. The arc-shaped block 7 is slidably connected inside the arc-shaped groove 5, allowing the arc-shaped block 7 to strike the connecting plate 4 through the arc-shaped groove 5. A locking block 8 is fixedly connected to the opposite side of the left and right arc-shaped blocks 7. The locking block 8 is engaged inside the connecting plate 4, allowing the connecting plate 4 to be limited by the locking block 8, thereby limiting the mesh plate 2.

[0025] When cleaning the mesh plate 2 is required, pulling the locking block 8 causes the arc-shaped block 7 to disengage from the slot 6 and from the connecting plate 4. At this time, pulling the mesh plate 2 forward causes the connecting slot 3 to move the connecting plate 4 forward. Then, by moving the locking block 8 in the opposite direction, the arc-shaped block 7 strikes the inside of the arc-shaped slot 5, causing the mesh plate 2 to vibrate. Repeating this action allows the arc-shaped block 7 to continuously vibrate the mesh plate 2, causing some dust on the outside of the mesh plate 2 to fall off and loosening stubborn stains, achieving a pre-cleaning effect. This not only reduces the labor intensity of workers but also increases cleaning efficiency.

[0026] Example 2: Based on Example 1, to facilitate the movement of the arc-shaped block 7, an installation groove 9 is provided on the other side of the inner wall of the connecting groove 3. Both the locking block 8 and the arc-shaped block 7 are slidably connected inside the installation groove 9. The installation groove 9 provides movement space for the arc-shaped block 7 and the locking block 8. An installation block 10 is fixedly connected to the end of the locking block 8 away from the arc-shaped block 7. The installation block 10 is slidably connected inside the installation groove 9. The installation groove 9 limits the installation block 10, preventing it from shifting during sliding. A pull rod is fixedly connected to the end of the installation block 10 away from the locking block 8. Rope 11 is slidably connected inside the mounting groove 9. The mounting groove 9 limits the movement of the rope 11, allowing it to slide smoothly. An elastic element 12 is sleeved on the outside of the rope 11. One end of the elastic element 12 is fixedly connected to the inner wall of the mounting groove 9, and the other end is fixedly connected to the mounting block 10. A rotating rod 13 is fixedly connected to the side of the rope 11 away from the mounting block 10. The rotating rod 13 is rotatably connected to the inside of the top of the fan body 1. The fan body 1 limits the movement of the rotating rod 13, allowing it to rotate smoothly.

[0027] When the arc-shaped block 7 needs to be moved, the rotating rod 13 is rotated so that one end of the pull rope 11 is wound around it, allowing the other end of the pull rope 11 to drive the locking block 8 and the arc-shaped block 7 to disengage from the inside of the connecting plate 4. This causes the elastic element 12 to deform, pulling the grid plate 2 to move outward. The grid plate 2 then moves the connecting plate 4 outward, allowing the arc-shaped block 7 to slide against the outside of the connecting plate 4. At this point, by releasing the pull rope 11 and continuing to pull the grid plate 2, when the arc-shaped block 7 moves to the position of the arc groove 5, the elastic element 12 performs a reset movement, pushing the mounting block 10 inward. This allows the mounting block 10 to push the arc-shaped block 7 to strike the arc groove 5 through the locking block 8. As the connecting plate 4 continues to move, the arc-shaped block 7 slides against the arc groove 5 and is pushed outward, allowing the arc-shaped block 7 to continuously strike the connecting plate 4.

[0028] Example 3: Based on Example 2, in order to provide installation stability for the fan body 1 and the grid plate 2, elastic elements 12 are provided on the adjacent sides of the two grid plates 2. The front and rear ends of the fan body 1 are fixedly connected with insert rings 15. The insert rings 15 are inserted into the inside of the sealing groove 14, thereby limiting the grid plate 2. A rubber ring 16 is fixedly connected to the outside of the insert ring 15. The rubber ring 16 fits into the inside of the sealing groove 14, so that the insert ring 15 and the sealing groove 14 can be flexibly connected, and the friction between the insert ring 15 and the rubber ring 16 is increased, so that the fan body 1 and the grid plate 2 can be stably connected.

[0029] When the grid plate 2 needs to be installed, the grid plate 2 is attached to the fan body 1. During this process, the insert ring 15 slides into the interior of the sealing groove 14, and the rubber ring 16 is deformed by the inner wall of the sealing groove 14. After the fan body 1 and the grid plate 2 are attached, the insert ring 15 is attached to the inner wall of the elastic element 12, so that the rubber ring 16 can perform a reset movement, and then the rubber ring 16 can fill the interior of the sealing groove 14, making the connection between the fan body 1 and the grid plate 2 more stable.

[0030] The working process of this utility model is as follows:

[0031] When cleaning of the mesh plate 2 is required, rotating the lever 13 causes it to wind one end of the pull rope 11, allowing the other end of the pull rope 11 to disengage the locking block 8 and the arc-shaped block 7 from the inside of the connecting plate 4. This causes the elastic element 12 to deform, pulling the mesh plate 2 outward. Consequently, the mesh plate 2 moves the connecting plate 4 outward, allowing the arc-shaped block 7 to slide against the outside of the connecting plate 4. At this point, by releasing the pull rope 11 and continuing to pull the mesh plate 2, when the arc-shaped block 7 moves to the position of the arc-shaped groove 5, the elastic element... The elastic element 12 can perform a reset movement, thereby allowing the elastic element 12 to push the mounting block 10 to move inward, so that the mounting block 10 can push the arc-shaped block 7 to strike the arc-shaped groove 5 through the locking block 8. As the connecting plate 4 continues to move, the arc-shaped block 7 can slide with the arc-shaped groove 5 and push the arc-shaped block 7 to move outward, so that the arc-shaped block 7 can continuously strike the connecting plate 4, causing some dust on the outside of the mesh plate 2 to fall off and loosening stubborn stains, achieving a pre-cleaning effect. This not only reduces the labor intensity of workers but also makes the cleaning efficiency higher.
