Description

Technical Field

[0001] This utility model relates to the field of air valve technology, and in particular to a self-cleaning magnetic air valve blade assembly. Background Technology

[0002] Magnetic damper blade assembly is a damper blade structural unit that uses magnetic attraction to position and close the blade. Its core feature is that it uses the adsorption between magnetic materials (such as permanent magnets and electromagnets) and metal parts (such as iron rings and magnetic metal sheets) to replace or assist traditional mechanical connection methods to achieve stable control of the blade.

[0003] Existing damper blade assemblies typically lack automatic cleaning functions and require manual wiping or disassembly for cleaning. In dusty, oily, or humid environments, the blades are prone to accumulating dirt, leading to increased airflow resistance, reduced ventilation efficiency, and even damper jamming. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning magnetic damper blade assembly. This device facilitates the self-cleaning of the blades, thus solving the problem of inconvenient self-cleaning of blades in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A self-cleaning magnetic damper blade assembly includes a housing, a chamber inside the side wall of the housing, a movable rod slidably connected inside the chamber, a permanent magnet fixedly connected to the upper end of the movable rod, an electromagnet disposed at the top of the chamber, the electromagnet cooperating with the permanent magnet, multiple connecting seats fixedly connected to the side wall of the movable rod, a plate slidably connected inside the top of the housing, a cleaning cotton fixedly connected to the side wall of the plate; multiple blades, the blades being disposed inside the housing, columns fixedly connected to both sides of each blade, the columns rotatably connected to the inner wall of the housing, a rotating block fixedly connected to the end of each column, the rotating block being hinged to the connecting seat.

[0007] Preferably, a vertical plate is fixedly connected between the upper and lower ends inside the housing, and the side wall of the vertical plate is provided with a groove.

[0008] Preferably, a protrusion is fixedly connected to the side wall of the plate, and the protrusion is slidably connected to the groove.

[0009] Preferably, a screw is rotatably connected inside the slot, and the upper and lower ends of the screw are respectively rotatably connected to the upper and lower ends inside the housing. The screw is threadedly connected to the protrusion.

[0010] Preferably, a motor is fixedly connected inside the upper end of the housing, and the output end of the motor is fixedly connected to the upper end of the screw via a coupling.

[0011] Preferably, a groove is provided at the top of the housing, and the groove is slidably connected to the protrusion, the plate and the cleaning cotton respectively.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. When the electromagnet is energized, it generates a constant magnetic force, which forms a strong attraction force with the permanent magnet. This ensures that the blade angle is fixed after the movable rod slides into place, avoiding angle deviation caused by mechanical wear or vibration, improving the accuracy of airflow regulation. The magnetic attraction force replaces the traditional gear or linkage mechanism, reducing mechanical friction and wear, extending component life, and reducing operating noise.

[0014] 2. The cleaning cotton slides in a straight line along the side wall of the blade under the action of the protrusion, ensuring that the air intake side surface is wiped evenly, avoiding the problem of local residues in traditional fixed cleaning brushes. Then, the cleaning cotton is driven to move back and forth by the motor in both forward and reverse directions, which can wipe stubborn stains a second time. It is especially suitable for cleaning long-term dirt in high dust or humid environments.

[0015] 3. The bumps, plates, and cleaning cotton are normally stored in the recesses of the shell, without occupying the internal space of the shell, avoiding additional resistance to airflow, and protecting the bumps, plates, and cleaning cotton from external environmental pollution.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A self-cleaning magnetic damper blade assembly includes a housing 001, a chamber 101 inside the side wall of the housing 001, a movable rod 102 slidably connected inside the chamber 101, a permanent magnet 103 fixedly connected to the upper end of the movable rod 102, an electromagnet 104 disposed at the top of the chamber 101, the electromagnet 104 cooperating with the permanent magnet 103, a plurality of connecting seats 105 fixedly connected to the side wall of the movable rod 102, and a plate 10 slidably connected inside the top of the housing 001. 9. A cleaning cotton 110 is fixedly connected to the side wall of plate 109; multiple blades 002 are located inside the housing 001. A column 201 is fixedly connected to both sides of each blade 002. The column 201 is rotatably connected to the inner wall of the housing 001. A rotating block 202 is fixedly connected to the end of the column 201. The rotating block 202 is hinged to the connecting seat 105. The operator fixes the housing 001 inside the designated pipe. When it is necessary to open the inside of the housing 001, the electromagnet 104 is activated. The electromagnet 103 generates a magnetic force that attracts the permanent magnet 103. The permanent magnet 103 pulls the movable rod 102 to slide upwards, and the movable rod 102 drives multiple connecting seats 105 to slide. The connecting seats 105 pull the rotating block 202 to rotate and tilt. At the same time, the rotating block 202 drives the blade 002 to rotate and tilt through the column 201. After the upper end of the permanent magnet 103 attracts and adheres to the lower end of the electromagnet 104, the blade 002 rotates to an appropriate angle, thereby opening the interior of the housing 001 and allowing external airflow to flow into the interior of the housing 001. When it is necessary to clean the air inlet side of the blade 002, multiple blades 002 rotate and close. Then, the plate 109 drives the cleaning cotton 110 to slide downwards. The side wall of the cleaning cotton 110 contacts the side wall of the blade 002 to clean the air inlet side of the blade 002. The electromagnet 104 closes and generates a magnetic force that repels the permanent magnet 103, thereby pushing the permanent magnet 103 to slide downwards. At the same time, the permanent magnet 103 pushes the movable rod 102 to slide downwards.

[0023] A vertical plate 003 is fixedly connected between the upper and lower ends inside the housing 001. A slot 301 is provided on the side wall of the vertical plate 003. The corner surface of the vertical plate 003 is located on the air inlet side of the housing 001. Through the corner surface of the vertical plate 003, the airflow flows to both sides of the vertical plate 003, preventing the airflow entering the housing 001 from contacting the inside of the slot 301.

[0024] A protrusion 108 is fixedly connected to the side wall of plate 109. The protrusion 108 is slidably connected to the groove 301, and the groove 301 guides and limits the protrusion 108.

[0025] A screw 302 is rotatably connected inside the slot 301. The upper and lower ends of the screw 302 are rotatably connected to the upper and lower ends inside the housing 001, respectively. The screw 302 is threadedly connected to the protrusion 108. When the screw 302 rotates, the protrusion 108 slides through the threaded engagement between the screw 302 and the protrusion 108.

[0026] A motor 106 is fixedly connected inside the upper end of the housing 001. The output end of the motor 106 is fixedly connected to the upper end of the screw 302 through a coupling. The output end of the motor 106 drives the screw 302 to rotate. A contact sensor is fixedly connected to the bottom inside the housing 001. The contact sensor is electrically connected to the motor 106. When the plate 109 contacts the sensor, the motor 106 operates in reverse, driving the screw 302 to rotate in the reverse direction.

[0027] A groove 107 is provided at the top of the housing 001. The groove 107 is slidably connected to the protrusion 108, the plate 109 and the cleaning cotton 110 respectively. The protrusion 108 drives the plate 109 and the cleaning cotton 110 to slide out of the groove 107 and slide into the slot 301. A contact switch is fixedly connected to the top of the groove 107. The contact switch is electrically connected to the motor 106. When the plate 109 contacts the contact switch, the motor 106 is turned off.

[0028] In this invention, the operator fixes the housing 001 inside a designated pipe. When it is necessary to open the inside of the housing 001, the electromagnet 104 is energized and generates a magnetic force that attracts the permanent magnet 103. The permanent magnet 103 pulls the movable rod 102 upward, and the movable rod 102 drives multiple connecting seats 105 to slide. The connecting seats 105 pull the rotating block 202 to rotate and tilt. At the same time, the rotating block 202 drives the blade 002 to rotate and tilt through the column 201. After the upper end of the permanent magnet 103 attracts and adheres to the lower end of the electromagnet 104, the blade 002 rotates to an appropriate angle, thereby opening the inside of the housing 001 and allowing external airflow to flow into the inside of the housing 001.

[0029] When cleaning is required on the air inlet side of blade 002, multiple blades 002 rotate and close. The output of motor 106 drives screw 302 to rotate. Through the threaded engagement between screw 302 and protrusion 108, protrusion 108 slides. Protrusion 108 drives plate 109 and cleaning cotton 110 to slide out from inside groove 107 and slide into slot 301. During this process, the sidewall of cleaning cotton 110 contacts the sidewall of blade 002, cleaning the air inlet side of blade 002. When plate 109 contacts sensor, motor 106 reverses operation, driving screw 302 to rotate in the opposite direction, causing protrusion 108 to drive plate 109 and cleaning cotton 110 to slide upward. When plate 109 contacts contact switch, motor 106 closes, and protrusion 108, plate 109 and cleaning cotton 110 are stored inside groove 107.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
