Description

Technical Field

[0001] This invention relates to the field of air purification equipment technology, specifically a novel dust-proof exhaust fan for air conditioning. Background Technology

[0002] Dust-proof induced draft fans are widely used for ventilation, dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced draft in boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; grain drying and conveying; wind tunnel air source and air filling and propulsion of hovercraft, etc.

[0003] However, existing dust-proof induced draft fans have a low level of intelligence. The filter material cannot automatically detach when it adsorbs a lot of dust. After long-term use, the filter material is easily blocked by dust, which can reduce ventilation efficiency. They cannot automatically clean and dry the filter material that has adsorbed a lot of dust, making it convenient for recycling. It is also inconvenient to replace the filter material, which increases the difficulty of using the device. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a novel dust-proof induced draft fan for air conditioning, which solves the problem of low intelligence in existing dust-proof induced draft fans. The filter material can automatically detach when it adsorbs a large amount of dust, avoiding the filter material from being clogged by dust and reducing ventilation efficiency after long-term use. It can automatically clean and dry the filter material that has adsorbed a large amount of dust, making it convenient for recycling and easy to replace the filter material, thus reducing the difficulty of using the device.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a novel dust-proof exhaust fan for air conditioning, comprising an exhaust casing, an air inlet at one end of the exhaust casing, an air outlet at the end of the exhaust casing away from the air inlet, and the interior of the exhaust casing being provided with:

[0008] The drive device has a mounting plate, a fan blade is rotatably connected to one side of the mounting plate, a drive motor is fixedly connected to the bottom inner side of the air duct, and the output end of the drive motor is connected to the rotating shaft of the fan blade via a belt.

[0009] The dustproof device includes a filter frame with filter plates evenly installed between its two sides. A metal rope is installed on the top of the filter frame. A magnet is fixedly connected to the top inner side of the exhaust box above the filter frame. Air in the exhaust box is discharged from the air outlet. Air outside the exhaust box enters the exhaust box after being filtered by the filter plates at the filter frame. When the filter plates have been filtering air for a long time and have accumulated a lot of dust, the attraction between the magnet and the metal rope is less than the overall weight of the suction frame. The suction frame falls to the bottom inner side of the exhaust box. This device can filter dust in the flowing air generated by the fan. When the filter material has accumulated too much dust, it automatically falls off, preventing dust from reducing the ventilation efficiency of the fan and ensuring the exhaust capacity of the fan.

[0010] The cleaning device includes a cleaning tank located at the bottom inner side of the outer casing of the air intake. A flexible cloth is fixedly connected between the two sides of the inner wall of the cleaning tank. A hydraulic cylinder is fixedly connected to the bottom inner side of the cleaning tank, below the flexible cloth. Cleaning water is poured into the cleaning tank. As the filter plate absorbs more dust, its increased weight causes it to fall. The filter frame and filter plate fall into the cleaning water inside the lower cleaning tank, where they are immersed and cleaned. The filter plate slides along the flexible cloth to the bottom, near the hydraulic cylinder. The hydraulic cylinder pushes the flexible cloth upwards, raising it. The filter frame and filter plate continue to slide along the inclined flexible cloth towards the fan blades until they are lifted by the hydraulic cylinder and the flexible cloth above the cleaning water. The airflow driven by the fan blades dries the filter frame and filter plate. This system allows for cleaning and drying of the filter material after it has absorbed a large amount of dust, facilitating the reuse of the filter material.

[0011] Preferably, a dustproof plate is rotatably connected to one side of the exhaust casing near the air outlet. The dustproof plate is made of foam board. When the fan is not exhausting air, the dustproof plate blocks the air outlet to prevent dust from the outside of the fan from entering the fan. After the fan starts to exhaust air, the flowing air pushes away the lighter dustproof plate, and the air inside the fan moves from the air outlet to the outside of the exhaust casing to begin exhausting air. This can prevent dust from entering the fan when the fan is not in use and improve the cleanliness of the fan's interior.

[0012] Preferably, a push plate is fixedly connected to one end of the top of the cylinder, and the top of the push plate is slidably connected to the flexible cloth.

[0013] Preferably, a horizontal plate is installed at the top end between the two sides of the inner wall of the filter frame, the horizontal plate is fixedly connected to the filter plate, and the filter plates are fixedly connected to each other by longitudinal columns.

[0014] Preferably, the inner wall of the filter frame has clamping grooves on one top end of both sides. A clamping plate is slidably connected to one side of the inner wall of the clamping groove. A compression spring is fixedly connected to the top of the clamping plate. The end of the compression spring away from the clamping plate is fixedly connected to the top of the inner side of the clamping groove. Both ends of the horizontal plate extend into the interior of the clamping groove. Pushing the clamping plate upward compresses the compression spring, raising the horizontal plate and moving it below the clamping plate. Releasing the clamping plate causes the clamping plate to be pushed by the compression spring to compress and fix the horizontal plate. When the filter plate adsorbs too much dust, the horizontal plate can be removed from below the clamping plate and replaced with a new horizontal plate and filter plate. This reduces the difficulty of replacing the filter material and makes the device easier to use.

[0015] Preferably, a base plate is installed on the inner bottom of the clamping groove. The base plate is slidably connected to one side of the inner wall of the clamping groove. Both ends of the metal rope pass through the filter frame and are fixedly connected to the base plate. The magnet attracts the metal rope to fix the filter frame to the inner top of the air duct outer box. The metal rope is pulled upward by the magnet, and the metal rope drives the base plate to move upward, clamping and fixing the horizontal plate and the filter frame from the bottom of the horizontal plate. This can increase the firmness of the filter material during use and prevent the filter material from falling off during use.

[0016] Preferably, a baffle plate is slidably connected to one side of the filter frame, and guide grooves are evenly provided on one side of the baffle plate.

[0017] Preferably, a material inlet is provided on one side of the outer casing near the cleaning tank, and a cover plate is rotatably connected to one side of the inner wall of the material inlet. A handle is fixedly connected to one side of the cover plate extending to the outside of the outer casing.

[0018] Preferably, the top of the flexible cloth is provided with uniformly distributed settling holes, and the bottom of the inner side of the cleaning tank is slidably connected with a receiving plate.

[0019] (III) Beneficial Effects

[0020] This invention provides a novel dust-proof induced draft fan for air conditioning. It has the following beneficial effects:

[0021] (I) This new type of dustproof exhaust fan for air conditioning exhausts air from the exhaust box through the air outlet. The air outside the exhaust box is filtered by the filter plate at the filter frame and then enters the exhaust box. When the filter plate has been filtering the air for a long time and the amount of dust adsorbed increases, the attraction between the magnet and the metal rope is less than the overall weight of the adsorption frame. The adsorption frame falls to the bottom of the inner side of the exhaust box, which can filter the dust in the flowing air generated by the fan. When the filter material adsorbs too much dust, it will automatically fall off, avoiding the dust from reducing the ventilation efficiency of the fan and ensuring the exhaust capacity of the fan.

[0022] (II) This new type of dustproof exhaust fan for air conditioning uses a dustproof plate to block the air outlet when the fan is not exhausting air, preventing dust from the outside of the fan from entering the fan. After the fan starts to exhaust air, the flowing air pushes away the lighter dustproof plate, and the air inside the fan moves from the air outlet to the outside of the exhaust box to begin exhausting air. This can prevent dust from entering the fan when the fan is not in use and improve the cleanliness of the fan's interior.

[0023] (III) The new dust-proof induced draft fan for air conditioning raises the horizontal plate by pushing the clamping plate upward to compress the squeeze spring. When the clamping plate is released, the clamping plate is pushed by the squeeze spring to squeeze the horizontal plate and fix it. When the filter plate has absorbed too much dust, the horizontal plate can be removed from under the clamping plate and a new horizontal plate and filter plate can be replaced. This reduces the difficulty of replacing the filter material and makes the device easier to use.

[0024] (iv) The new dustproof exhaust fan for air conditioning uses a magnetic block to attract a metal rope to fix the filter frame to the top of the inner side of the exhaust box. The metal rope is pulled upward by the magnetic block, and the metal rope drives the bottom plate to move upward, clamping and fixing the horizontal plate and the filter frame from the bottom of the horizontal plate. This can increase the firmness of the filter material during use and prevent the filter material from falling off during use.

[0025] (V) This new type of dust-proof exhaust fan for air conditioning works by pouring cleaning water into the cleaning tank. After the filter plate absorbs a lot of dust, its weight increases and it falls off. The filter frame and filter plate fall into the cleaning water in the cleaning tank below. The filter plate is soaked and cleaned by the cleaning water. The filter plate slides along the flexible cloth to the bottom position close to the oil cylinder. The oil cylinder pushes the flexible cloth upward and raises it. The filter frame and filter plate continue to slide along the inclined flexible cloth towards the fan blade until they are lifted by the oil cylinder and the flexible cloth to the top of the cleaning water. The air flow driven by the fan blade dries the filter frame and filter plate. This allows the filter material to be cleaned and dried after absorbing a lot of dust, which is convenient for the reuse of the filter material.

[0026] (vi) The dust-proof induced draft fan for air conditioning uses the cleaning water inside the cleaning tank to clean the filter plate. After the dust is cleaned, it settles down from the settling holes on the flexible cloth and falls onto the receiving plate. The settled dust is cleaned from the receiving plate, which can centrally clean the filtered dust and reduce the difficulty of dust cleaning. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please see Figure 1-5 This invention provides a technical solution: a novel dustproof exhaust fan for air conditioning, comprising an exhaust casing 1, an air inlet 2 at one end of the exhaust casing 1, an air outlet 3 at the end of the exhaust casing 1 away from the air inlet 2, and the interior of the exhaust casing 1 being provided with:

[0036] The drive device 4 has a mounting plate 41, a fan blade 42 is rotatably connected to one side of the mounting plate 41, and a drive motor 43 is fixedly connected to the bottom inner side of the air duct 1. The output end of the drive motor 43 is connected to the rotating shaft of the fan blade 42 via a belt 44.

[0037] The dustproof device 5 has a filter frame 51, filter plates 52 are evenly installed between the two sides of the filter frame 51, a metal rope 53 is installed on the top of the filter frame 51, and a magnet block 54 is fixedly connected to the top of the inner side of the air-exhaust outer box 1 above the filter frame 51.

[0038] A dustproof plate 7, which is made of foam board, is rotatably connected to one side of the outer casing 1 near the air outlet 3.

[0039] A horizontal plate 9 is installed at the top end between the two sides of the inner wall of the filter frame 51. The horizontal plate 9 is fixedly connected to the filter plate 52. The filter plates 52 are fixedly connected to each other by longitudinal columns 10.

[0040] The filter frame 51 has a clamping groove 11 on one of the top ends of both sides of its inner wall. A clamping plate 12 is slidably connected to one side of the inner wall of the clamping groove 11. A compression spring 13 is fixedly connected to the top of the clamping plate 12. The end of the compression spring 13 away from the clamping plate 12 is fixedly connected to the top of the inner side of the clamping groove 11. Both ends of the horizontal plate 9 extend into the interior of the clamping groove 11.

[0041] A base plate 14 is installed on the bottom inner side of the clamping groove 11. The base plate 14 is slidably connected to one side of the inner wall of the clamping groove 11. Both ends of the metal rope 53 pass through the filter frame 51 and are fixedly connected to the base plate 14.

[0042] A baffle plate 15 is slidably connected to one side of the filter frame 51, and guide grooves are evenly opened on one side of the baffle plate 15.

[0043] In use, the filter frame 51 moves into the interior of the air intake box 1. Due to the attraction between the top magnet 54 and the metal rope 53, the filter frame 51 is attracted and fixed to the top inner side of the air intake box 1. The drive motor 43 drives the fan blades to rotate, and the air in the air intake box 1 is discharged from the air outlet 3. The air outside the air intake box 1 enters the interior of the air intake box 1 after being filtered by the filter plate 52 at the filter frame 51. When the filter plate 52 has been filtering the air for a long time and has accumulated a lot of dust, the attraction between the magnet 54 and the metal rope 53 is less than the overall weight of the suction frame 51. The suction frame 51 falls to the bottom inner side of the air intake box 1, which can filter the dust in the flowing air generated by the fan. When the filter material has absorbed too much dust, it will automatically fall off to avoid dust reducing the ventilation efficiency of the fan and ensuring the exhaust capacity of the fan.

[0044] Push the clamping plate 12 upward to compress the compression spring 13, raising it and moving the horizontal plate 9 below the clamping plate 12. Release the clamping plate, and the clamping plate 12 is pushed by the compression spring 13 to compress and fix the horizontal plate 9. When the filter plate 52 has absorbed too much dust, remove the horizontal plate 9 from below the clamping plate 12 and replace it with a new horizontal plate 9 and filter plate 52. This reduces the difficulty of replacing the filter material and makes the device easier to use.

[0045] The magnet 54 attracts the metal rope 53 to fix the filter frame 51 to the top of the inner side of the air intake box 1. The metal rope 53 is pulled upward by the magnet 54, and the metal rope 53 drives the base plate 14 to move upward, clamping and fixing the horizontal plate 9 and the filter frame 51 from the bottom of the horizontal plate 9. This can increase the firmness of the filter material during use and prevent the filter material from falling off during use.

[0046] Example 2

[0047] Please see Figure 1-5 The present invention provides a technical solution: Based on the first embodiment, a cleaning device 6 is provided inside the outer casing 1 of the air duct. The cleaning device 6 has a cleaning tank 61, which is opened at the bottom inner side of the outer casing 1. A flexible cloth 62 is fixedly connected between the two sides of the inner wall of the cleaning tank 61, and a hydraulic cylinder 63 is fixedly connected at the bottom inner side of the cleaning tank 61 below the flexible cloth 62.

[0048] A push plate 8 is fixedly connected to one end of the top of the hydraulic cylinder 63, and the top of the push plate 8 is slidably connected to the flexible cloth 62.

[0049] A material inlet 16 is provided on one side of the outer casing 1 near the cleaning tank 61. A cover plate 17 is rotatably connected to one side of the inner wall of the material inlet 16. A handle 18 is fixedly connected to one side of the cover plate 17 extending to the outside of the outer casing 1.

[0050] The top of the flexible cloth 62 is evenly provided with settling holes, and the bottom of the inner side of the cleaning tank 61 is slidably connected with a receiving plate.

[0051] In use, cleaning water is poured into the cleaning tank 61. After the filter plate 52 absorbs a lot of dust, its weight increases and it falls off. The filter frame 51 and the filter plate 52 fall into the cleaning water inside the cleaning tank 61 below. The filter plate 52 is soaked and cleaned by the cleaning water. The filter plate 52 slides along the flexible cloth 62 to the bottom, close to the oil cylinder 63. The oil cylinder 63 pushes the flexible cloth 62 upward and raises it. The filter frame 51 and the filter plate 52 continue to slide along the inclined flexible cloth 62 towards the fan blade 42 until they are lifted by the oil cylinder 63 and the flexible cloth 62 and rise above the cleaning water. The airflow driven by the fan blade 42 dries the filter frame 51 and the filter plate 52. This allows the filter material to be cleaned and dried after absorbing a lot of dust, making it convenient for the filter material to be reused.
