Description

Technical Field

[0001] This invention relates to the field of heating, ventilation and air conditioning technology, specifically to a heating, ventilation and air conditioning fan speed regulating device based on indoor temperature and its usage method. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) is a comprehensive system that encompasses heating, ventilation, and air conditioning. Its main purpose is to create a comfortable environment inside a building, including controlling indoor temperature, humidity, air quality, and ventilation.

[0003] Patent application number CN202022260356.2 relates to the field of air conditioning and ventilation technology, and discloses an HVAC ventilation valve, including a ventilation pipe. A drive motor is installed inside the ventilation pipe, and the output end of the drive motor is fixedly connected to the right end of a rotating shaft. A fan blade is installed on the outer wall of the left end of the rotating shaft. A dust removal screen is installed on the left side of the ventilation pipe, and the right side of the top of the dust removal screen is fixedly connected to the left side of a second connecting rod. The right end of the second connecting rod extends through the left side of the housing to contact the inner wall of the right side of the housing. This HVAC ventilation valve, by pulling a pin to the left, causes the pin to... The pull rod is disengaged. At this point, pulling the pull rod upwards causes the moving block to move upwards, which in turn causes the movable rod to deflect and the fixed block to move the insert rod to the left. By pulling the insert rod upwards until the bottom end of the insert rod moves above the second connecting rod, the dust filter can be pulled out, thus completing the disassembly. However, when this device is used continuously, the outside temperature will rise. When the heating and air conditioning system continuously blows air at high speed, the outside temperature will continue to rise, leading to discomfort for indoor occupants. Therefore, a heating, ventilation, and air conditioning fan speed adjustment device based on indoor temperature and its usage method are proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a heating, ventilation and air conditioning fan speed regulating device based on indoor temperature and its usage method, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a heating, ventilation, and air conditioning (HVAC) fan speed regulating device based on indoor temperature, comprising a housing, and further comprising a filter device, a collection device, and a guiding device; a heating tube is installed on the inner wall of the housing, a support plate is fixedly connected to the inner wall of the housing, a rotating block is rotatably connected to the left side of the support plate, blades are fixedly connected to the surface of the rotating block, a bevel gear set is rotatably connected to the right side of the support plate, a transmission rod is rotatably connected to the inner wall of the housing, a friction block is fixedly connected to the bottom end of the transmission rod, and a temperature sensor is fixedly connected to the bottom of the friction block. The device comprises a mounting plate fixedly connected to the bottom of the housing, two clamping plates rotatably connected to the bottom of the housing, a rotating plate rotatably connected to the inner wall of the clamping plates, and a double-ended screw threaded to the inner wall of the rotating plate. A motor is fixedly connected to the right side of the mounting plate. A filter device is disposed on the inner wall of the housing, a collection device is disposed at the bottom of the housing, and a guide device is disposed on the inner wall of the housing. The right end of the rotating block is fixedly connected to one output end of a bevel gear set via a connecting rod, and the other output end of the bevel gear set is fixedly connected to the top end of a transmission rod. The surface of the clamping plate is flush with the surface of the friction block. The motor's output end is fixedly connected to the right end of the bidirectional screw, and the surface of the bidirectional screw is rotatably connected to the inner wall of the mounting plate. The temperature sensor is electrically connected to the motor. When the air conditioner blows air from the casing from right to left, the air comes into contact with the heating element and is heated, causing hot air to blow out from the left. Simultaneously, the blown air comes into contact with the blades and pushes them to rotate via the inclined plane. The faster the airflow, the faster the blades rotate. When the indoor temperature exceeds the preset value of the temperature sensor, an electrical signal is sent to the motor. Upon receiving the signal, the motor starts and drives the bidirectional screw to rotate. The screw drives two rotating plates to converge, which in turn drives two clamping plates to converge and contact the friction block. At this point, the friction between the friction block and the clamping plates increases. The blades then drive the rotating block to rotate, which in turn drives the bevel gear set to rotate. The bevel gear set drives the transmission rod to rotate, which in turn drives the friction block to rotate. The clamping plates then limit the friction block's rotational speed, thus slowing down the blades. The air blown out will then hit the slowly rotating blades, which block the airflow, thereby reducing the speed of the hot air blown out. This allows the fan speed to be automatically adjusted according to the indoor temperature.

[0006] Preferably, the filtering device includes a filter plate, a rotating rod, a reducer, a connecting rod, a fixed block, and a scraper. The filter plate is fixedly connected to the inner wall of the housing, the rotating rod is rotatably connected to the inner wall of the filter plate, the reducer is installed on the left side of the filter plate, the connecting rod is fixedly connected to the left input end of the reducer, the fixed block is fixedly connected to the right end of the rotating rod, and the scraper is fixedly connected to the surface of the fixed block. The filtering device also includes a reciprocating screw, a roller, and a moving plate. The reciprocating screw is rotatably connected to the surface of the fixed block, the roller is fixedly connected to the end of the reciprocating screw away from the fixed block, and the moving plate is movably connected to the surface of the reciprocating screw. The left end of the connecting rod is fixedly connected to the surface of the bevel gear set, the right output end of the reducer is fixedly connected to the left end of the rotating rod, the left side of the scraper is in contact with the right side of the filter plate, the surface of the roller is in contact with the right side of the filter plate, and the surface of the reciprocating screw is provided with cross-shaped spiral grooves. The inner wall of the movable plate is equipped with a locking block located in a cross-shaped spiral groove. The surface of the movable plate is in contact with the surface of the scraper. When the air conditioner blows air, it passes through the filter plate, which filters dust from the air, thereby reducing the amount of dust in the room. When the bevel gear set rotates, it drives the connecting rod to rotate. The connecting rod drives the rotating rod to rotate through the reducer. The rotating rod drives the fixed block to rotate, which in turn drives the scraper to rotate. The rotating scraper scrapes away the dust accumulated on the filter plate, preventing dust from accumulating on the filter plate and causing blockage, which would affect the ventilation effect. At the same time, the rotation of the fixed block drives the reciprocating screw to rotate, which in turn drives the roller to rotate. The roller contacts the filter plate and rolls on the filter plate. At this time, the roller rotates itself and drives the reciprocating screw to rotate. The reciprocating screw drives the movable plate to move back and forth on the scraper, which further scrapes away the dust adhering to the scraper surface, improving the dust removal and cleaning effect.

[0007] Preferably, the collecting device includes a collecting box and a baffle. The collecting box is installed at the bottom of the housing, and the baffle is fixedly connected to the inner wall of the collecting box. The collecting device also includes an elastic plate, a pressure plate, an elastic sheet, a push block, and a clamping block. The two sides of the elastic plate are fixedly connected to the inner wall of the collecting box. The pressure plate is fixedly connected to the lower surface of the elastic plate. There are two push blocks, which are slidably connected to the inner wall of the collecting box. The clamping block is fixedly connected to the side of the two push blocks close to each other. The elastic sheet is fixedly connected between the two push blocks. The bottom of the pressure plate is in contact with the lower surface of the elastic sheet. The surface of the roller is in contact with the upper surface of the elastic plate. The bottom of the clamping block is in contact with the inner wall of the collecting box. When the dust on the scraper is scraped off... At this time, the baffle blocks the incoming wind, allowing the scraped dust to fall into the collection box, thus collecting the dust and preventing it from being blown up again. Simultaneously, the roller is driven to rotate by the reciprocating screw, causing the roller to squeeze out and deform the elastic plate. The elastic plate pushes the pressure plate down, which in turn pushes the elastic sheet to deform. The elastic sheet then pushes two push blocks to move in opposite directions, moving and squeezing the dust in the collection box. When the elastic plate returns to its original position due to its own elasticity, it causes the pressure plate to move up. At this time, the elastic sheet also returns to its original position due to its own elasticity and causes the two push blocks to converge. The push blocks then cause the clamping blocks to converge, squeezing the dust in the middle again, thereby reducing the volume of dust and increasing the amount of dust collected in the collection box, thus improving space utilization.

[0008] Preferably, the guiding device includes a turntable, a limiting rod, a push rod, a moving rod, an elastic telescopic rod, a guide plate, and a brush rod. The turntable is fixedly connected to the left side of the rotating block, the limiting rod is fixedly connected to the left side of the turntable, the push rod is slidably connected to the inner wall of the top of the housing, the moving rod is fixedly connected to the left side of the push rod, the elastic telescopic rod is rotatably connected to the bottom of the moving rod, the guide plate is fixedly connected to the lower surface of the elastic telescopic rod via a connecting rod, the brush rod is fixedly connected to the right side of the guide plate, the bottom of the elastic telescopic rod is rotatably connected to the top of the housing, the surface of the limiting rod is in contact with the inner wall of the push rod, and the surface of the guide plate is in contact with the inner wall of the housing. When the rotating block rotates, it drives the turntable to rotate, the turntable drives the limiting rod to rotate, and the limiting rod is in contact with the push rod. The rotation displacement causes the push rod body to move back and forth reciprocally. The push rod then moves the moving rod, which in turn causes the elastic telescopic rod to swing back and forth. The elastic telescopic rod then causes the guide plate to swing, guiding the air blown out by the air conditioner, increasing the area of ​​the warm air and improving the indoor temperature rise. When the air conditioner fan speed decreases, the rotation speed of the rotating block will also slow down. At this time, the swing speed of the guide plate will also slow down, which will further slow down the swing speed of the guide plate after the indoor temperature rises. At the same time, the guide plate will drive the brush rod to move, scraping off the dust adhering to the surface of the heating element to prevent dust from accumulating on the surface of the heating element and affecting the heating effect. The dust on the surface of the heating element is caused by dust entering the housing from the left side of the housing and adhering to the surface of the heating element when the air conditioner is not in use.

[0009] A method for using a heating, ventilation, and air conditioning (HVAC) fan speed regulating device based on indoor temperature includes the following steps:

[0010] Step 1: When the air conditioner blows air out from the casing from right to left, the air will come into contact with the heating element and be heated, so that the hot air blows out from the left side. The blown air will come into contact with the blades and push the blades to rotate through the inclined surface. The faster the air is blown out, the faster the blades rotate.

[0011] Step 2: When the indoor temperature is higher than the preset value of the temperature sensor, an electrical signal will be sent to the motor. When the motor receives the electrical signal, it will start and drive the bidirectional screw to rotate. The bidirectional screw will drive the two rotating plates to converge, and the rotating plates will drive the two clamping plates to converge and contact the friction block.

[0012] Step 3: The friction between the friction block and the clamp increases. At this time, the blade will drive the rotating block to rotate, the rotating block will drive the bevel gear set to rotate, the bevel gear set will drive the transmission rod to rotate, and the transmission rod will drive the friction block to rotate. At this time, the clamp will limit the friction block's friction, thereby reducing the friction block's rotation speed, which will cause the blade's rotation speed to slow down. The blown air will blow onto the slowly rotating blade, and the blade will block the blown air, thereby reducing the wind speed of the blown hot air. Thus, the wind speed can be automatically adjusted according to the indoor temperature.

[0013] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0014] 1. The HVAC fan speed adjustment device based on indoor temperature and its usage method, through the coordinated operation of the housing, heating pipe, support plate, rotating block, blades, bevel gear set, transmission rod, mounting plate, clamping plate, rotating plate, bidirectional screw, motor, friction block, and temperature sensor, when the indoor temperature is higher than the preset value of the temperature sensor, the motor will start and drive the clamping plate to limit the friction block, thereby reducing the rotation speed of the friction block, which will cause the blade rotation speed to slow down, and the blown air will blow on the slowly rotating blades. The blades will block the blown air, thereby reducing the wind speed of the blown hot air, and thus automatically adjusting the fan speed according to the indoor temperature.

[0015] 2. This HVAC fan speed regulating device based on indoor temperature and its usage method, through the coordinated operation of a filter plate, rotating rod, reducer, connecting rod, fixed block, scraper, reciprocating screw, roller, and moving plate, allows air to pass through the filter plate when the air conditioner delivers air. The filter plate filters dust from the air, thereby reducing the amount of dust indoors. When the bevel gear set rotates, it drives the connecting rod to rotate. The connecting rod, through the reducer, drives the rotating rod to rotate. The rotating rod drives the fixed block to rotate. The fixed block drives the scraper to rotate. The rotating scraper removes the dust accumulated on the filter plate, preventing dust from accumulating on the filter plate and causing blockage, thus affecting the ventilation effect.

[0016] 3. The HVAC fan speed regulating device based on indoor temperature and its usage method, through the coordinated operation of the collection box, baffle, elastic plate, pressure plate, elastic sheet, push block, and clamping block, when the dust on the scraper is scraped off, the baffle will block the incoming airflow, allowing the scraped dust to fall into the collection box, thereby collecting the scraped dust and preventing it from being blown up again. At the same time, the push block will drive the clamping block to gather and squeeze the dust in the middle again, thereby reducing the volume of dust, increasing the amount of dust collected in the collection box, and improving space utilization.

[0017] 4. This HVAC fan speed regulating device based on indoor temperature and its usage method, through the coordinated operation of a turntable, a limiting rod, a push rod, a moving rod, an elastic telescopic rod, a guide plate, and a brush rod, causes the rotating block to rotate, which in turn causes the turntable to rotate. The turntable then causes the limiting rod to rotate and shift within the push rod, causing the push rod body to move back and forth. The push rod then causes the moving rod to move, which in turn causes the elastic telescopic rod to swing back and forth. The elastic telescopic rod then causes the guide plate to swing, and the guide plate guides the air blown out by the air conditioner, increasing the area of ​​the warm air blown out and improving the indoor temperature rise rate.

[0028] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-5One embodiment of the present invention is: a heating, ventilation, and air conditioning (HVAC) fan speed regulating device based on indoor temperature and its usage method, comprising a housing 1, a filter device 4, a collection device 5, and a guide device 6; a heating tube 2 is installed on the inner wall of the housing 1, a support plate 3 is fixedly connected to the inner wall of the housing 1, a rotating block 31 is rotatably connected to the left side of the support plate 3, blades 32 are fixedly connected to the surface of the rotating block 31, a bevel gear set 33 is rotatably connected to the right side of the support plate 3, a transmission rod 34 is rotatably connected to the inner wall of the housing 1, a friction block 310 is fixedly connected to the bottom end of the transmission rod 34, a temperature sensor 311 is fixedly connected to the bottom of the friction block 310, and the bottom of the housing 1 is fixedly connected to... The housing 1 has a mounting plate 35, and two clamping plates 36 are rotatably connected to the bottom of the housing 1. A rotating plate 37 is rotatably connected to the inner wall of the clamping plate 36, and a double-ended screw 38 is threaded onto the inner wall of the rotating plate 37. A motor 39 is fixedly connected to the right side of the mounting plate 35. A filter device 4 is installed on the inner wall of the housing 1, a collecting device 5 is installed at the bottom of the housing 1, and a guide device 6 is installed on the inner wall of the housing 1. When the air conditioner blows air from the housing 1 from right to left, the air will come into contact with the heating pipe 2 and be heated, causing the hot air to blow out from the left side. At the same time, the blown air will come into contact with the blades 32 and push the blades 32 to rotate through the inclined plane. The faster the blown air speed, the faster the blades 32 rotate. When the indoor temperature is higher than the specified value, the air conditioner will rotate faster. When the temperature sensor 311 reaches its preset value, it sends an electrical signal to the motor 39. Upon receiving the signal, the motor 39 starts and drives the bidirectional screw 38 to rotate. The bidirectional screw 38 then drives the two rotating plates 37 to converge. The right end of the rotating block 31 is fixedly connected to one output end of the bevel gear set 33 via a connecting rod. The other output end of the bevel gear set 33 is fixedly connected to the top end of the transmission rod 34. The surface of the clamping plate 36 is in contact with the surface of the friction block 310. The output end of the motor 39 is fixedly connected to the right end of the bidirectional screw 38. The surface of the bidirectional screw 38 is rotatably connected to the inner wall of the mounting plate 35. The temperature sensor 311 and the motor 39 are electrically connected. The rotating plate 37... 7 will cause the two clamping plates 36 to converge and contact the friction block 310. At this time, the friction between the friction block 310 and the clamping plate 36 increases. At this time, the blade 32 will drive the rotating block 31 to rotate, the rotating block 31 will drive the bevel gear set 33 to rotate, the bevel gear set 33 will drive the transmission rod 34 to rotate, and the transmission rod 34 will drive the friction block 310 to rotate. At this time, the clamping plate 36 will limit the friction of the friction block 310, thereby reducing the rotational speed of the friction block 310, which will cause the speed of the blade 32 to slow down. The blown air will blow on the slowly rotating blade 32. The blade 32 will block the blown air, thereby reducing the wind speed of the blown hot air, and thus the wind speed can be automatically adjusted according to the indoor temperature.

[0030] The filter device 4 includes a filter plate 41, a rotating rod 42, a reducer 43, a connecting rod 44, a fixing block 45, and a scraper 46. The filter plate 41 is fixedly connected to the inner wall of the housing 1, the rotating rod 42 is rotatably connected to the inner wall of the filter plate 41, the reducer 43 is installed on the left side of the filter plate 41, the connecting rod 44 is fixedly connected to the left input end of the reducer 43, the fixing block 45 is fixedly connected to the right end of the rotating rod 42, and the scraper 46 is fixedly connected to the surface of the fixing block 45. When the air conditioner blows air, it passes through the filter plate 41, and the filter plate 41 filters the dust in the air. This reduces indoor dust levels. When the bevel gear set 33 rotates, it drives the connecting rod 44 to rotate. The connecting rod 44, through the reducer 43, drives the rotating rod 42 to rotate. The rotating rod 42 drives the fixed block 45 to rotate. The fixed block 45 drives the scraper 46 to rotate. The rotating scraper 46 scrapes away the dust accumulated on the filter plate 41, preventing dust from accumulating on the filter plate 41 and causing blockage, thus affecting ventilation. The filter device 4 also includes a reciprocating screw 461, a roller 462, and a moving plate 463. The reciprocating screw 461 rotates to connect... The roller 462 is fixedly connected to the end of the reciprocating screw 461 away from the fixed block 45, and the moving plate 463 is movably connected to the surface of the reciprocating screw 461. The left end of the connecting rod 44 is fixedly connected to the surface of the bevel gear set 33, the right output end of the reducer 43 is fixedly connected to the left end of the rotating rod 42, the left side of the scraper 46 is in contact with the right side of the filter plate 41, the surface of the roller 462 is in contact with the right side of the filter plate 41, the surface of the reciprocating screw 461 is provided with a cross-shaped spiral groove, and the inner wall of the moving plate 463 is provided with a locking block. The block is located in the cross-shaped spiral groove. The surface of the moving plate 463 is in contact with the surface of the scraper 46. When the fixed block 45 rotates, it will drive the reciprocating screw 461 to rotate. The reciprocating screw 461 will drive the roller 462 to rotate. The roller 462 will contact the filter plate 41 and roll on the filter plate 41. At this time, the roller 462 will rotate itself and drive the reciprocating screw 461 to rotate itself. The reciprocating screw 461 will drive the moving plate 463 to move back and forth on the scraper 46. The moving plate 463 will further scrape off the dust adhering to the surface of the scraper 46, improving the dust removal and cleaning effect.

[0031] Working principle: When the air conditioner blows air from the casing 1 from right to left, the air comes into contact with the heating element 2 and is heated, causing the hot air to blow out from the left. At the same time, the blown air comes into contact with the blades 32 and pushes the blades 32 to rotate through the inclined plane. The faster the airflow, the faster the blades 32 rotate. When the indoor temperature is higher than the preset value of the temperature sensor 311, it sends an electrical signal to the motor 39. When the motor 39 receives the electrical signal, it starts and drives the bidirectional screw 38 to rotate. The bidirectional screw 38 drives the two rotating plates 37 to converge, and the rotating plates 37 drive the two clamping plates 36 to converge and contact the friction block 310. At this time, the friction between the friction block 310 and the clamping plate 36 increases. The blade 32 will drive the rotating block 31 to rotate, the rotating block 31 will drive the bevel gear set 33 to rotate, the bevel gear set 33 will drive the transmission rod 34 to rotate, and the transmission rod 34 will drive the friction block 310 to rotate. At this time, the clamping plate 36 will limit the friction of the friction block 310, thereby reducing the rotational speed of the friction block 310, which will cause the rotational speed of the blade 32 to slow down. The blown air will blow onto the slowly rotating blade 32. The blade 32 will block the blown air, thereby reducing the wind speed of the blown hot air, and thus the wind speed can be automatically adjusted according to the indoor temperature.

[0032] When the air conditioner blows air, it passes through the filter plate 41, which filters dust from the air, thus reducing the amount of dust indoors. When the bevel gear set 33 rotates, it drives the connecting rod 44 to rotate. The connecting rod 44, through the reducer 43, drives the rotating rod 42 to rotate. The rotating rod 42 drives the fixed block 45 to rotate, and the fixed block 45 drives the scraper 46 to rotate. The rotating scraper 46 scrapes away the dust accumulated on the filter plate 41, preventing dust from accumulating on the filter plate 41 and causing the filter plate 41 to become dry. Blockage can affect ventilation. When the fixed block 45 rotates, it will drive the reciprocating screw 461 to rotate. The reciprocating screw 461 will drive the roller 462 to rotate. The roller 462 will contact the filter plate 41 and roll on the filter plate 41. At this time, the roller 462 will rotate itself and drive the reciprocating screw 461 to rotate itself. The reciprocating screw 461 will drive the moving plate 463 to move back and forth on the scraper 46. The moving plate 463 will further scrape off the dust adhering to the surface of the scraper 46, improving the dust removal and cleaning effect.

[0033] Please see Figure 5-9Based on the above embodiments, in another embodiment of the present invention, the collecting device 5 includes a collecting box 51 and a baffle 52. The collecting box 51 is installed at the bottom of the housing 1, and the baffle 52 is fixedly connected to the inner wall of the collecting box 51. When the dust on the scraper 46 is scraped off, the baffle 52 blocks the blowing air, allowing the scraped dust to fall into the collecting box 51, thereby collecting the scraped dust and preventing the dust from being blown out again. The collecting device 5 also includes an elastic plate 521, a pressure plate 522, an elastic sheet 523, a push block 524, and a clamping block 525. The two sides of the elastic plate 521 are fixedly connected to the inner wall of the collecting box 51, the pressure plate 522 is fixedly connected to the lower surface of the elastic plate 521, two push blocks 524 are provided, and the two push blocks 524 are slidably connected to the inner wall of the collecting box 51, the clamping block 525 is fixedly connected to the side of the two push blocks 524 close to each other, and the elastic sheet 523 is fixedly connected to the two push blocks 524. Between; the bottom of the pressure plate 522 contacts the lower surface of the elastic sheet 523, the surface of the roller 462 contacts the upper surface of the elastic plate 521, and the bottom of the clamping block 525 contacts the inner wall of the collection box 51. The roller 462 is then driven to rotate by the reciprocating screw 461. The roller 462 will squeeze out and push the elastic plate 521 to deform. The elastic plate 521 will push the pressure plate 522 to move downward. The pressure plate 522 will push the elastic sheet 523 to deform. The two push blocks 524 will move in opposite directions. The push blocks 524 will move and push and squeeze the dust in the collection box 51. When the elastic plate 521 resets by its own elasticity, it will drive the pressure plate 522 to move upward. At this time, the elastic sheet 523 will also reset by its own elasticity and drive the two push blocks 524 to gather together. The push blocks 524 will drive the clamping block 525 to gather together and squeeze the dust in the middle again, thereby reducing the volume of dust and increasing the amount of dust collected in the collection box 51, thus improving the space utilization rate.

[0034] The guiding device 6 includes a turntable 61, a limiting rod 62, a push rod 63, a moving rod 64, an elastic telescopic rod 641, a guide plate 642, and a brush rod 643. The turntable 61 is fixedly connected to the left side of the rotating block 31, the limiting rod 62 is fixedly connected to the left side of the turntable 61, the push rod 63 is slidably connected to the inner wall of the top of the housing 1, the moving rod 64 is fixedly connected to the left side of the push rod 63, the elastic telescopic rod 641 is rotatably connected to the bottom of the moving rod 64, and the guide plate 642 is fixedly connected to the lower surface of the elastic telescopic rod 641 via a connecting rod. When the rotating block 31 rotates, it drives the turntable 61 to rotate, which in turn drives the limiting rod 62 to rotate. The limiting rod 62 rotates and displaces within the push rod 63, causing the push rod 63 to move back and forth. The push rod 63 drives the moving rod 64 to move, which in turn causes the elastic telescopic rod 641 to swing back and forth. The elastic telescopic rod 641 then causes the guide plate 642 to swing. 2. The air blown out by the air conditioner is guided to increase the area of ​​the warm air and increase the indoor temperature rise. The brush rod 643 is fixedly connected to the right side of the guide plate 642. The bottom of the elastic telescopic rod 641 is rotatably connected to the top of the housing 1. The surface of the limit rod 62 is in contact with the inner wall of the push rod 63. The surface of the guide plate 642 is in contact with the inner wall of the housing 1. When the air conditioner fan speed decreases, the rotation speed of the rotating block 31 will also slow down. At this time, the swing speed of the guide plate 642 will slow down. Then, after the indoor temperature rises, the swing speed of the guide plate 642 will slow down. At the same time, the guide plate 642 will drive the brush rod 643 to move. The brush rod 643 will scrape off the dust adhering to the surface of the heating tube 2 to prevent the dust from accumulating on the surface of the heating tube 2 and affecting the heating effect of the surface of the heating tube 2. The dust on the surface of the heating tube 2 is caused by the dust entering the housing 1 from the left side when the air conditioner is not in use and adhering to the surface of the heating tube 2.

[0035] Working principle: When the dust on the scraper 46 is scraped off, the baffle 52 blocks the incoming airflow, allowing the scraped dust to fall into the collection box 51. This collects the scraped dust and prevents it from being blown up again. At the same time, the roller 462 is driven to rotate by the reciprocating screw 461. The roller 462 squeezes against the elastic plate 521 and pushes the elastic plate 521 to deform. The elastic plate 521 pushes the pressure plate 522 downward, and the pressure plate 522 pushes the elastic sheet 523 to deform. The elastic sheet 523 will push the two push blocks 524 to move in opposite directions. The push blocks 524 will move and push and squeeze the dust in the collection box 51. When the elastic plate 521 resets through its own elasticity, it will drive the pressure plate 522 to move upward. At this time, the elastic sheet 523 will also reset through its own elasticity and drive the two push blocks 524 to gather together. The push blocks 524 will drive the clamping block 525 to gather together and squeeze the dust in the middle again, thereby reducing the volume of dust and increasing the amount of dust collected in the collection box 51, thus improving the space utilization rate.

[0036] When the rotating block 31 rotates, it drives the turntable 61 to rotate. The turntable 61 then drives the limiting rod 62 to rotate. The limiting rod 62 rotates and shifts within the push rod 63, causing the push rod 63 to move back and forth. The push rod 63 then drives the moving rod 64 to move. The moving rod 64 then drives the elastic telescopic rod 641 to swing back and forth. The elastic telescopic rod 641 then drives the guide plate 642 to swing. The guide plate 642 guides the air blown out by the air conditioner, increasing the area of ​​the warm air and improving the indoor temperature rise rate. When the air conditioner fan speed decreases, it rotates... The rotation speed of block 31 will also slow down. At this time, the swing speed of guide plate 642 will slow down. As the room temperature rises, the swing speed of guide plate 642 will slow down. At the same time, guide plate 642 will drive brush rod 643 to move. Brush rod 643 will scrape off the dust adhering to the surface of heating tube 2 to prevent dust from accumulating on the surface of heating tube 2 and affecting the heating effect of the surface of heating tube 2. The dust on the surface of heating tube 2 is caused by the dust entering the housing 1 from the left side of the housing 1 and adhering to the surface of heating tube 2 when the air conditioner is not in use.

10. The method for using the HVAC wind speed adjustment device based on indoor temperature according to claim 9, characterized in that: The following steps are involved: Step 1: When the air conditioning wind is blown out from the housing (1) from right to left, the wind will contact the heating tube (2) and be heated, so that the hot wind is blown out from the left side. The blown wind will contact the blades (32) and push the blades (32) to rotate through the inclined surface. The faster the blown wind speed is, the faster the blades (32) rotate. Step 2: When the indoor temperature is higher than the preset value of the temperature sensor (311), an electrical signal is sent to the motor (39). When the motor (39) receives the electrical signal, it starts and drives the bidirectional screw (38) to rotate. The bidirectional screw (38) drives the two rotating plates (37) to gather together.

The blade (32) blocks the blown wind, thereby reducing the wind speed of the blown hot wind, and the wind speed can be automatically adjusted according to the indoor temperature.
