Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning dust removal, in particular to an automatic dust removal device for a clean air-conditioning. Background Art

[0002] Clean air conditioning is an air conditioning system specially designed to control indoor air cleanliness, temperature, humidity and air flow distribution. The working principle of clean air conditioning mainly includes air filtration, temperature and humidity adjustment, air flow distribution and exhaust system.

[0003] For example, a clean air conditioner, with the publication number CN218721907U, monitors the dust in the air in real time through a dust sensor during use. When the dust sensor detects that the dust in the air is too large and exceeds a preset value, the first valve group controls the spray head to open and spray water mist. The water mist sprayed by the spray head makes the dust particles in the air moist and drop, so that a part of the dust can fall directly into the dust outlet trough, and the wet dust particles are more likely to stick to the first filter and be filtered, so as to improve the dust filtration effect. The dust accumulated on the first filter is scraped off by setting a scraper assembly, and the movement of the scraper assembly is controlled by the first valve group. By setting a humidity sensor in the air outlet, when the humidity sensor detects that the humidity in the air exceeds the preset value, the second valve group 8 can open the dehumidification pipe, so that the air passes through the dehumidification pipe and enters the indoor air conditioner unit of the room. If the humidity in the air does not exceed the preset value, the air enters the indoor air conditioner unit through the ordinary pipe.

[0004] However, part of the sprayed water mist is adsorbed in the first filter under the action of suction, which will cause the first filter to become moist. Therefore, in actual use, the dust will become wet and muddy due to the water vapor. Therefore, when the scraper contacts the surface of the first filter, the moist dust will be squeezed into the first filter. Long-term accumulation will cause the first filter to become clogged.

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figure 1-6 As shown, a clean air conditioner automatic dust removal device includes a known air duct 1 installed at the air inlet of the air conditioner and a known filter 2 arranged in the air duct 1. The outer wall of one side of the air duct 1 is fixedly connected to the position of the filter 2, and the inner wall of the shell 3 is slidably connected to the lifting cover 4 on both sides of the filter 2. The lifting cover 4 extends into the air duct 1, and the two lifting covers 4 are lifted and lowered at the same time, so that the filter 2 located between the two lifting covers 4 is not ventilated, and the cover openings of the two lifting covers 4 are arranged opposite to each other, and a hot air blower 8 is provided on the side of the lifting cover 4 on the leeward side of the filter 2, and a dust collecting cover 5 is plugged into the bottom of the lifting cover 4 on the windward side of the filter 2. In actual use, the surface of the filter 2 clamped by the two lifting covers 4 is not used for dust filtering in the air because it is separated from other areas. Therefore, the hot air generated by starting the hot air blower 8 passes through the surface of the filter 2 clamped by the two lifting covers 4. When the filter screen 2 is dried, the filter screen 2 in the area will be dried, and the lifting cover 4 rotates relative to the cover wall and is connected to two brush rollers 10 and a striking shaft 16 located between the two brush rollers 10. The brush rollers 10 and the striking shaft 16 are arranged perpendicular to the outer shell 3 and are interference fit with the surface of the filter screen 2. The dry dust on the surface of the dried filter screen 2 will be broken under the rotation action of the rotating striking shaft 16, and the two brush rollers 10 that are arranged rotate to achieve the drying and broken dust falling, and under the action of the hot air from the hot air blower 8, the dust enters the dust collecting cover 5 at the bottom of the lifting cover 4 on the windward side of the filter screen 2 for collection. The specific structure of the additional brush roller 10 is a rod body and a number of brushes installed on the surface of the rod body, and the specific structure of the set striking shaft 16 is a rod body and a long strip installed on the surface of the rod body. The rotation of the rod body is used to realize the rotation of the long strip and repeatedly act on the surface of the filter screen 2 to achieve striking.

[0026] Furthermore: the side wall of the dust hood 5 facing the filter 2 is hollowed out for a built-in filter and cooperates with the gap on the surface of the filter 2. The hollow setting ensures the separation of the hot air entering the dust hood 5 and the dust mixed in the hot air, so that the dust is trapped in the dust hood 5, and the hot air is blown out through the hollow part and acts on the surface of the filter 2, thereby preheating and drying the surface of the filter 2; a pair of adjacent outer walls of the lifting hood 4 close to the outer shell 3 are rotatably connected to the sealing roller 9 that is rollingly connected to the surface of the filter 2, ensuring that the lifting hood 4 rotates by using the sealing roller 9 to reduce friction when lifting and lowering, and uses the sealing roller 9 to contact the surface of the filter 2, that is, the guaranteed seal can prevent the lifting hood 4 from scratching the surface of the filter 2 on the hood mouth side.

[0027] Furthermore, a screw rod 7 with a thread running through the lifting cover 4 is rotatably connected in the housing 3, and the end faces of the two screw rods 7 on the same side are fixedly connected to a pulley 6 and one of the screw rods 7 is driven by a motor. A belt strip is connected between the two pulleys 6. By installing a motor on the housing 3 to drive one of the screw rods 7 to rotate, and using the belt strip to connect the pulley 6 installed on the end face of the screw rod 7, it is possible to achieve that when one of the screw rods 7 actively rotates under the driving action of the motor, the other screw rod 7 is driven to passively rotate, and the lifting cover 4 threadedly connected to the screw rod 7 is lifted and lowered, that is, the two lifting covers 4 are lifted and lowered synchronously, and the surface of the screw rod 7 is provided with a plurality of strips along the length direction. Keyway 18, the top surface of the lifting cover 4 is rotatably connected with a splice gear ring 11 which is sleeved on the screw rod 7 and whose inner arc surface is plugged into the keyway 18. The surface of the lifting cover 4 is also provided with a pinion 12 which is meshed with the splice gear ring 11 and an end bevel gear 13 fixed to the end face of the pinion 12. The keyway 18 is set to ensure that when the screw rod 7 rotates, the splice gear ring 11 on the surface of the lifting cover 4 is driven to rotate relative to the lifting cover 4, thereby realizing the meshing connection of the pinion 12 and driving the end bevel gear 13 on its end face to rotate. Because the splice gear ring 11 and the pinion 12 are of different sizes, when the splice gear ring 11 rotates, it will drive the pinion 12 to rotate at a higher speed.

[0028] Further: the side of the lifting cover 4 near the end bevel gear 13 is rotatably connected with a universal coupling 15, and the two parts of the universal coupling 15 are rotatably connected with the lifting cover 4, and one part of the rod extends into the lifting cover 4, and the other part is fixedly connected with a transmission bevel gear 14 meshing with the end bevel gear 13. The lifting cover 4 is located on the side wall of the end face of the brush roller 10 and is rotatably connected with a number of linearly distributed spur gears 17. Two adjacent spur gears 17 are meshed and connected, and three of the spur gears 17 are respectively connected with the two brush rollers 10. It is fixed to the end face of the striking shaft 16, and one of the spur gears 17 is fixed to the end face of the part of the rod body extending from the universal coupling 15 to the lifting cover 4. When the end bevel gear 13 rotates, it drives the meshing transmission bevel gear 14 to rotate. The connection of the universal coupling 15 is utilized to realize that when the transmission bevel gear 14 rotates, the corresponding spur gear 17 is driven to rotate. Because the two adjacent spur gears 17 are meshed and connected, when one of the spur gears 17 rotates, the spur gears 17 at other positions also rotate, so the rotation of the brush roller 10 and the striking shaft 16 can be realized.

[0029] Working principle: when in use, the lifting cover 4 is lifted and lowered by rotating the screw rod 7 and passing through the surface of the filter screen 2. When the screw rod 7 rotates, the keyway 18 on its surface is used to rotate the plug-in gear ring 11, thereby driving the pinion 12 to rotate at a higher speed. The pinion 12 drives the end bevel gear 13 on its end face to rotate. When the end bevel gear 13 rotates, it drives the meshing transmission bevel gear 14 to rotate. The universal coupling 15 is used to connect the transmission bevel gear 14 to rotate the corresponding spur gear 17. Because the two adjacent spur gears 17 are meshed and connected, one of them The spur gear 17 rotates, and the spur gears 17 at other positions also rotate, so that the brush roller 10 and the striking shaft 16 can rotate. When the hot air generated by starting the hot blower 8 passes through the surface of the filter 2 clamped by the two lifting covers 4, the filter 2 in the area will be dried. The dried filter 2 will be broken into pieces by the rotating striking shaft 16, and the two brush rollers 10 will rotate to achieve the drying and breaking of the dust. The dust will then be blown into the dust collecting hood 5 at the bottom of the lifting cover 4 on the windward side of the filter 2 by the hot air from the hot blower 8 and collected.

[0030] The wiring diagram of the motor and the hot air blower 8 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the motor and the hot air blower 8 are no longer explained in detail.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
