Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically to a ventilation and air conditioning system for heating equipment. Background Technology

[0002] Heating equipment refers to equipment used in specific scenarios. It generates heat through methods such as burning fuel, converting electrical energy, or heat transfer to raise the temperature of an indoor or specific space and meet heating needs. It encompasses various types such as centralized heating systems, air conditioners, and electric heaters. Its core function is to create a warm and comfortable environment for users through different heat transfer principles. It is adaptable to different space sizes, usage needs, and energy conditions, and has wide applicability and diverse selection. Currently, the air outlets of heating equipment are usually adjusted by opening and closing louvered blades.

[0003] The patent document with authorization announcement number CN220103368U discloses an air volume regulating device for HVAC. This air volume regulating device includes a ventilation duct and an regulating mechanism. The ventilation duct has an air outlet at its lower end connected to an air inlet at its upper end. The regulating mechanism includes a first sprocket, a second sprocket, a chain, and a baffle plate. The baffle plate is rotatably connected between the left and right walls of the ventilation duct via a rotating shaft. The second sprocket is located at the right end of the rotating shaft and is situated within the inner cavity of the right wall of the ventilation duct. The first sprocket is rotatably connected to the inner cavity of the right wall of the ventilation duct via a rotating shaft. The first and second sprockets are connected by a chain drive. The device also includes a microcontroller located at the front end of the air outlet duct, with its input terminal electrically connected to an external power source.

[0004] However, the structural design of the aforementioned technologies allows for adjustment of the air deflector angle. When the heating equipment is not in use, the air deflector is usually closed to prevent dust from entering. When the heating equipment is turned on again, the motor can only drive the air deflector to the default angle, making it inconvenient for the air deflector to automatically adjust according to the previous airflow angle of the heating equipment.

[0005] Therefore, a ventilation and air conditioning system for heating equipment is proposed to solve the problems mentioned above. Summary of the Invention

[0006] This invention provides a ventilation and air conditioning system for heating equipment, aiming to solve the problem in related technologies where the wind deflector cannot be automatically adjusted according to the previous airflow angle.

[0007] The heating equipment ventilation and air conditioning system of the present invention includes a heating mechanism and a housing, wherein a blower mechanism is installed on the housing, and an adjustment mechanism is provided inside the blower mechanism.

[0008] The blower mechanism includes a fixed frame on the housing and a sweeping assembly 1 inside the fixed frame, the sweeping assembly 1 being hinged to an adjustment mechanism 1.

[0009] The adjustment mechanism includes a drive assembly disposed on the inner wall of the fixed frame, a rotating assembly inserted into one end of the drive assembly, a fixed plate disposed on the outside of the rotating assembly, and a limiting assembly slidably disposed on the inner side of the fixed plate. The inner side of the fixed plate is provided with a plurality of limiting slots arranged in a ring array. The limiting assembly has a plug-in member that can be inserted into the limiting slot. The limiting assembly is provided with an elastic member connected to the rotating assembly. The rotating assembly is hinged to the air sweeping assembly to adjust the air outlet angle.

[0010] The drive assembly includes a drive member, on which an external spline shaft that can rotate and move axially is connected; the rotation assembly includes a rotating plate, one end of which is provided with an internal spline groove that mates with the external spline shaft, and the interior of the rotating plate has a push rod that moves the connector out of the limiting groove.

[0011] When the angle of the first air-sweeping assembly needs to be adjusted, the external spline shaft on the drive component moves into the inner spline groove, causing the external spline shaft to push the push rod. At this time, the push rod pushes the connector in the limit assembly out of the limit groove of the fixed plate, causing the limit assembly to change from the locked state to the unlocked state. Subsequently, the drive component drives the rotating plate to rotate through the inner spline groove. When the rotating plate rotates, it can adjust the angle of the first air-sweeping assembly. When the fixed frame needs to be closed, the external spline shaft on the drive component is reset. At this time, the connector in the limit assembly is inserted into the limit groove of the fixed plate, causing the limit assembly to reset to the locked state. Subsequently, the drive component drives the first air-sweeping assembly to close through the rotating plate, thereby closing the fixed frame. At the same time, the elastic element between the limit assembly and the rotating assembly stores force. When the drive component is restarted, the elastic element is released, driving the rotating plate and the first air-sweeping assembly to reset to the position before the last closure.

[0012] Preferably, the drive assembly further includes a telescopic component, a mounting plate, and a rotating shaft. The telescopic component and the drive component are both mounted on one side of the mounting plate. The movable end of the telescopic component is mounted on the inner wall of the fixed frame. The rotating shaft is mounted on the drive component. The external spline shaft is mounted on the rotating shaft. The end of the external spline shaft has an arc-shaped surface for pushing the push rod.

[0013] When the external spline shaft needs to move into the inner spline groove, the movable end of the telescopic component extends. At this time, the telescopic component drives the rotating shaft on the drive component to move through the mounting plate. The rotating shaft can drive the external spline shaft to move, so as to adjust the position of the external spline shaft in the inner spline groove.

[0014] Preferably, the rotating plate has a through hole, the inner spline groove is formed on the inner wall of the through hole, the rotating plate has a sliding groove on the outer side near the through hole, the top rod is slidably connected in the sliding groove, and its top end passes through the rotating plate and abuts against the limiting component, its bottom end passes through the sliding groove and extends into the interior of the through hole, and a limiting ring is installed on its outer side that is slidably connected to the sliding groove.

[0015] During the process of the external spline shaft moving inside the inner spline groove, the external spline shaft can push the push rod upward. At this time, the push rod can push the limiting component, causing the connector in the limiting component to move out of the limiting groove.

[0016] Preferably, the fixed plate has a rotating cavity, the rotating plate is rotatably connected to the inside of the rotating cavity, the limiting groove is formed on the inner wall of the rotating cavity, and the limiting component is slidably disposed on the inner wall of the rotating cavity.

[0017] Preferably, a fixing block is installed on the outer side of the rotating plate, a second spring is installed on one side of the fixing block, and one end of the second spring is installed on the limiting assembly.

[0018] During the process of adjusting the angle of the first air-sweeping assembly by the driving component, the rotating plate drives the limiting assembly to rotate synchronously through the second spring on the fixed block. When the first air-sweeping assembly is closed by the driving component, the limiting assembly is locked on the inner wall of the rotating cavity, so that when the driving component drives the rotating plate to rotate, the fixed block can drive the second spring to stretch.

[0019] Preferably, the limiting component includes a sliding seat and a top plate. The sliding seat is slidably connected to the inner wall of the rotating cavity. One end of the second spring is mounted on the sliding seat. The plug is disposed inside the sliding seat. The top plate is slidably connected to the inside of the sliding seat, and the top of the top plate abuts against the plug. The bottom of the top plate penetrates the sliding seat and abuts against the top of the push rod.

[0020] Preferably, the connector includes a rotating shaft, a rotating block, a limiting plate, a limiting shaft, a connecting plate, and a spring. The rotating shaft is rotatably connected to the sliding seat. The rotating block is mounted on the rotating shaft and has a through groove. The top plate abuts against one side of the bottom of the rotating block. The limiting plate is slidably connected in the through groove and can also be inserted into the limiting groove. The limiting shaft is mounted on one bottom side of the limiting plate and located at the bottom of the rotating block. The connecting plate is located above the rotating block and mounted on the limiting plate. The spring is installed between the connecting plate and the inner top wall of the sliding seat.

[0021] When the push rod moves upward, it pushes the rotating block to rotate through the top plate. The rotating block drives the limiting plate to move downward and out of the limiting groove through the limiting shaft, while simultaneously stretching the spring. When the push rod returns to its original position, the spring drives the limiting plate to move upward through the connecting plate and insert into the limiting groove to lock the sliding seat.

[0022] Preferably, the fixed frame is connected to the heating mechanism, and the side of the fixed frame opposite to the heating mechanism has an air outlet. Both sides of the inner wall of the air outlet of the fixed frame have two vertical plates extending into the fixed frame. The air sweeping component is disposed in the air outlet of the fixed frame.

[0023] Preferably, the first air-sweeping assembly includes a movable plate, a second hinge plate, and multiple air-sweeping components. The movable plate is movably disposed on one side of one of the upright plates of the fixed frame. One end of the second hinge plate is hinged to the movable plate, and the other end of the second hinge plate is hinged to the rotating plate. The multiple air-sweeping components are rotatably connected between the two upright plates of the fixed frame.

[0024] Preferably, the air-sweeping component includes a rotating rod, a first hinge plate, a fixed shaft, and an air-sweeping plate. The air-sweeping plate is rotatably disposed between two upright plates of the fixed frame. One end of the fixed shaft is installed on one side of the air-sweeping plate, one end of the first hinge plate is installed on the other end of the fixed shaft, and the other end of the first hinge plate is hinged to the rotating rod. The rotating rod is rotatably connected to the movable plate.

[0025] By adopting the above technical solution, the beneficial effects of the present invention are as follows: When it is necessary to close the fixed frame, the external spline shaft on the drive component is reset. At this time, the plug in the limit component is inserted into the limit groove of the fixed plate, so that the limit component is reset to the locked state. Subsequently, the drive component drives the air sweeping component to close through the rotating plate, thereby closing the fixed frame. At the same time, the elastic element between the limit component and the rotating component stores force. When the drive component is restarted, the elastic element is released, driving the rotating plate and the air sweeping component to reset to the position before the last closure. Thus, when the heating mechanism is restarted, there is no need to adjust the blowing angle, which is more convenient to use. Attached Figure Description

[0043] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0044] like Figures 1 to 11As shown, the heating equipment ventilation and air conditioning system of the present invention includes a heating mechanism 10, a housing 20, and a blower mechanism 30. The housing 20 is installed on one side of the heating mechanism 10, and there are two blower mechanisms 30, which are symmetrically arranged on the top of one side of the housing 20. Each of the two blower mechanisms 30 is provided with an adjustment mechanism 40 and an adjustment mechanism 50 inside.

[0045] Hot air blown from the heating mechanism 10 enters the housing 20 and is blown out through the blower mechanism 30. During the blowing process, the airflow direction of the blower mechanism 30 is adjusted by the first adjustment mechanism 40 and the second adjustment mechanism 50. When the heating mechanism 10 is turned off, the air outlet of the blower mechanism 30 is sealed by the first adjustment mechanism 40 and the second adjustment mechanism 50. When the heating mechanism 10 is turned on, the airflow direction of the blower mechanism 30 can be adjusted back to the position before it was turned off by the first adjustment mechanism 40 and the second adjustment mechanism 50.

[0046] like Figures 1 to 3 As shown, the blower mechanism 30 includes a fixed frame 31, a first sweeping assembly 32, and a second sweeping assembly 33. The fixed frame 31 is installed on the top side of one side of the housing 20 and is connected to the heating mechanism 10. The side of the fixed frame 31 opposite to the heating mechanism 10 has an air outlet, and both sides of the inner wall of the air outlet of the fixed frame 31 have two vertical plates extending into the interior of the fixed frame 31. The first sweeping assembly 32 is disposed in the air outlet of the fixed frame 31 and is hinged to the first adjusting mechanism 40. A horizontal plate is provided on one side of the interior of the fixed frame 31, and the horizontal plate in the fixed frame 31 is positioned close to the first sweeping assembly 32. The second sweeping assembly 33 and the second adjusting mechanism 50 are both disposed on the horizontal plate of the fixed frame 31, and the second sweeping assembly 33 is hinged to the second adjusting mechanism 50. The first and second sweeping assemblies 32 have the same structure, with the first sweeping assembly 32 vertically positioned inside the fixed frame 31 and the second sweeping assembly 33 horizontally positioned inside the fixed frame 31.

[0047] When the heating system 10 is turned on, the first adjustment mechanism 40 drives the first air-sweeping component 32 to rotate, thereby changing the up-down airflow direction of the air outlet on the fixed frame 31. Simultaneously, the second adjustment mechanism 50 drives the second air-sweeping component 33 to rotate, thereby changing the left-right airflow direction of the air outlet on the fixed frame 31. When the heating system 10 is turned off and then on again, the first adjustment mechanism 40 and the second adjustment mechanism 50 respectively drive the first air-sweeping component 32 and the second air-sweeping component 33 back to their positions before being turned off, eliminating the need for further adjustment and making it convenient to use.

[0048] like Figures 2 to 4As shown, the air-sweeping assembly 32 includes a movable plate 321, air-sweeping components, and a hinged plate 327. The movable plate 321 is movably mounted on one side of one of the upright plates of the fixed frame 31. One end of the hinged plate 327 is hinged to the bottom of one side of the movable plate 321, and the other end is hinged to the adjusting mechanism 40. The air-sweeping components are rotatably connected between the two upright plates of the fixed frame 31. There are multiple air-sweeping components, which are evenly spaced vertically.

[0049] The air-sweeping component includes a rotating rod 322, a hinge plate 323, a fixed shaft 324, an air-sweeping plate 325, and a connecting shaft 326. The fixed shaft 324 and the connecting shaft 326 are respectively installed on both sides of the air-sweeping plate 325, which is positioned between two upright plates of the fixed frame 31. One end of the fixed shaft 324 passes through one of the upright plates of the fixed frame 31 and extends to the outer side of the upright plate. One end of the hinge plate 323 is installed on one end of the fixed shaft 324, and the other end of the hinge plate 323 is hinged to one end of the rotating rod 322. The other end of the rotating rod 322 is rotatably connected to the movable plate 321.

[0050] When adjusting the angle of the sweeping plate 325, the adjusting mechanism 40 can drive the movable plate 321 to move through the hinge plate 327. The movable plate 321 can drive the sweeping plate 325 to rotate around the fixed axis 324 through the hinge plate 323 on the rotating rod 322, so as to adjust the angle of the sweeping plate 325 and thus adjust the up and down air direction of the air outlet on the fixed frame 31.

[0051] When it is necessary to close the air outlet of the fixed frame 31, the adjustment mechanism 40 drives the air sweeping plate 325 to rotate to a vertical position through the hinge plate 327, so as to close the air outlet of the fixed frame 31 and prevent dust and other debris from entering the fixed frame 31.

[0052] The adjustment principle of the second air-sweeping component 33 is the same as that of the first air-sweeping component 32, and will not be described again here.

[0053] like Figures 2 to 5 and Figure 7As shown, the adjustment mechanism 40 includes a drive assembly 41, a rotating assembly 42, a mounting assembly 43, a limiting assembly 44, a second spring 45, and a fixing block 46. The drive assembly 41 is disposed on one side of the inner wall of the fixed frame 31, and the mounting assembly 43 is located on one side of the drive assembly 41 and mounted on the inner wall of the fixed frame 31. The rotating assembly 42 is rotatably disposed inside the mounting assembly 43, and the drive assembly 41 is inserted into one end of the rotating assembly 42. The other end edge of the rotating assembly 42 is hinged to the second hinge plate 327. The limiting assembly 44 is located outside the rotating assembly 42 and slidably disposed inside the mounting assembly 43. In the initial state, the limiting assembly 44 is inserted into the mounting assembly 43. The fixing block 46 is mounted outside the rotating assembly 42 and spaced apart from the limiting assembly 44. The two ends of the second spring 45 are respectively mounted on the limiting assembly 44 and the fixing block 46.

[0054] When the angle of the air sweeper 325 needs to be adjusted, the drive assembly 41 moves inside the rotating assembly 42 and pushes the limiting assembly 44, causing the limiting assembly 44 and the mounting assembly 43 to change from a plug-in state to a sliding state. Subsequently, the drive assembly 41 drives the rotating assembly 42 to rotate inside the mounting assembly 43. During the rotation, the rotating assembly 42 drives the air sweeper 325 to rotate through the hinge plate 327, while the fixing block 46 drives the limiting assembly 44 to slide inside the mounting assembly 43 through the spring 45.

[0055] When it is necessary to close the air outlet of the fixed frame 31, the drive assembly 41 resets in the rotating assembly 42. At this time, the limiting assembly 44 and the mounting assembly 43 change from a sliding state to a plugging state. Then, the drive assembly 41 drives the sweeping plate 325 to a vertical state through the hinge plate 327 on the rotating assembly 42, while the spring 45 is in a stretched state.

[0056] When the air outlet of the fixed frame 31 is closed by the sweeping plate 325, the drive component 41 self-locks, thereby locking the rotating component 42. When it is necessary to reopen the air outlet of the fixed frame 31, the drive component 41 unlocks, allowing the rotating component 42 to rotate. At this time, the force of the spring 45 returning to its original position drives the rotating component 42 to rotate through the fixed block 46. The rotating component 42 drives the sweeping plate 325 to rotate to the angle before it was closed last time through the hinge plate 327, thus eliminating the need to readjust the angle of the sweeping plate 325 again, making it more convenient to use.

[0057] like Figure 3 and Figure 6As shown, the drive assembly 41 includes a telescopic member 411, a mounting plate 412, a drive member 413, a rotating shaft 414, and an external splined shaft 415. Both the telescopic member 411 and the drive member 413 are mounted on one side of the mounting plate 412. The movable end of the telescopic member 411 passes through the mounting plate 412 and is mounted on the inner wall of the fixed frame 31. In this embodiment, the telescopic member 411 is a telescopic motor; in other embodiments, the telescopic member 411 can be a cylinder or a hydraulic cylinder. One end of the rotating shaft 414 is mounted on the drive shaft of the drive member 413, and one end of the external splined shaft 415 is mounted on the other end of the rotating shaft 414. The external splined shaft 415 is inserted into the rotating assembly 42, and the other end of the external splined shaft 415 has an arc-shaped surface. In this embodiment, the drive member 413 is a stepper motor with brake pads. It should be noted that when the drive component 413 is de-energized, the brake pads on the drive component 413 lock the drive shaft. When the drive component 413 is energized, the brake pads on the drive component 413 unlock the drive shaft, allowing the drive shaft on the drive component 413 to rotate under the action of external force.

[0058] When the angle of the air sweeper 325 needs to be adjusted, the telescopic member 411 drives the drive member 413 to move through the mounting plate 412. The drive member 413 drives the external spline shaft 415 to extend further into the rotating assembly 42 through the rotating shaft 414, so that the limiting assembly 44 and the mounting assembly 43 change from the plug-in state to the sliding state. Subsequently, the drive member 413 drives the rotating assembly 42 to rotate through the external spline shaft 415. The rotating assembly 42 drives the air sweeper 325 to rotate through the hinge plate 327 to adjust the angle of the air sweeper 325.

[0059] like Figures 3 to 8 As shown, the rotating assembly 42 includes a rotating plate 421, a hinge shaft 422, a push rod 426, and a limiting ring 427. The rotating plate 421 is rotatably connected to the mounting assembly 43, and a through hole 423 is formed at the center of the rotating plate 421. The hinge shaft 422 is installed on one end edge of the rotating plate 421, and one end of the hinge plate 427 is hinged to the hinge shaft 422. An inner spline groove 424 is formed at the other end of the rotating plate 421 and communicates with the through hole 423. A sliding groove 425 is also formed inside the rotating plate 421 near the outer side of the through hole 423. The push rod 426 is slidably connected inside the sliding groove 425. The top end of the push rod 426 passes through the rotating plate 421 and abuts against the limiting assembly 44, and the bottom end of the push rod 426 passes through the sliding groove 425 and extends into the interior of the through hole 423. The limiting ring 427 is installed on the outer side of the push rod 426 and is slidably connected to the interior of the sliding groove 425. In the initial state, the external spline shaft 415 is inserted into the internal spline groove 424, and the end of the external spline shaft 415 is positioned close to the bottom end of the push rod 426.

[0060] When the limiting component 44 and the mounting component 43 need to be unlocked, the telescopic component 411 drives the driving component 413 to move through the mounting plate 412. The driving component 413 drives the outer spline shaft 415 to move into the inner spline groove 424 through the rotating shaft 414. At the same time, the end of the outer spline shaft 415 pushes the push rod 426 upward, so that the push rod 426 can push the limiting component 44. At this time, the limiting component 44 and the mounting component 43 change from the plugged state to the sliding state.

[0061] like Figure 3 and Figure 7 As shown, the mounting assembly 43 includes a fixed plate 431, a rotating cavity 432, and a limiting groove 433. The fixed plate 431 is mounted on one side of the inner wall of the fixed frame 31, and the rotating cavity 432 is formed on the fixed plate 431. The rotating plate 421 is rotatably connected to the inside of the rotating cavity 432, the fixing block 46 is mounted on the outside of the rotating plate 421, and the limiting assembly 44 is slidably connected to the inner wall of the rotating cavity 432. There are multiple limiting grooves 433, which are arranged in a circular array on the inner wall of the rotating cavity 432, and the limiting assembly 44 can be inserted into the limiting grooves 433.

[0062] When the limiting component 44 needs to be inserted into the limiting groove 433, the telescopic component 411 drives the driving component 413 to reset via the mounting plate 412. At the same time, the driving component 413 drives the external spline shaft 415 to reset via the rotating shaft 414. At this time, the external spline shaft 415 disengages from the push rod 426, so that the push rod 426 resets. When the push rod 426 resets, the limiting component 44 is inserted into the limiting groove 433 of the rotating cavity 432 to fix the limiting component 44.

[0063] like Figures 7 to 11 As shown, the limiting assembly 44 includes a sliding seat 441, a rotating shaft 442, a rotating block 443, a top plate 445, a limiting plate 446, a limiting shaft 447, a connecting plate 448, and a spring 449. The sliding seat 441 is slidably connected to the inner wall of the rotating cavity 432 of the fixed plate 431. One end of the spring 45 is installed on one side of the sliding seat 441, and the rotating shaft 442 is rotatably connected to the inside of the sliding seat 441. The rotating block 443 is installed on the outside of the rotating shaft 442, and a through groove 444 is provided on one side of the top of the rotating block 443. The top plate 445 abuts against the bottom side of the rotating block 443, and the bottom of the top plate 445 penetrates the bottom of the sliding seat 441 and abuts against the top end of the push rod 426. Both sides of the top plate 445 have protrusions. In the initial state, the protrusions on the top plate 445 are in contact with the inner bottom wall of the sliding seat 441. The limiting plate 446 is slidably connected in the through groove 444, and the bottom of the limiting plate 446 passes through the through groove 444 and extends to the outside of the through groove 444. In the initial state, the top of the limiting plate 446 passes through the top of the sliding seat 441 and is inserted into the limiting groove 433 of the rotating cavity 432.

[0064] There are two limiting shafts 447, which are respectively installed on the bottom sides of the limiting plate 446 and located at the bottom of the rotating block 443. The connecting plate 448 is located above the rotating block 443 and installed on one side of the limiting plate 446. The bottom end of the spring 449 is installed on the top of the connecting plate 448, and the top end of the spring 449 is installed on the inner top wall of the sliding seat 441.

[0065] The structure and principle of the second regulating mechanism 50 are the same as those of the first regulating mechanism 40 mentioned above, and will not be repeated here.

[0066] When the telescopic component 411 drives the driving component 413 to move via the mounting plate 412, the driving component 413 drives the outer spline shaft 415 to move into the inner spline groove 424 via the rotating shaft 414, causing the end of the outer spline shaft 415 to push the push rod 426 upward. During the upward movement of the push rod 426, it can push the top plate 445 in the sliding seat 441 upward, and at the same time, the top plate 445 pushes the rotating block 443 to rotate around the rotating shaft 442. During the rotation of the rotating block 443, it can drive the limiting plate 446 downward via the limiting shaft 447, thereby allowing the limiting plate 446 to move out of the limiting groove 433 of the rotating cavity 432, and at the same time, the spring 449 is in a stretched state. At this time, when the driving component 413 drives the rotating plate 421 to rotate via the outer spline shaft 415, the rotating plate 421 can drive the sliding seat 441 to slide on the inner wall of the rotating cavity 432 via the spring 45 on the fixed block 46.

[0067] When the telescopic component 411 drives the driving component 413 to reset via the mounting plate 412, the driving component 413 drives the external spline shaft 415 to reset via the rotating shaft 414. At this time, the external spline shaft 415 disengages from the top rod 426. The resetting force of the spring 449 then drives the limiting plate 446 to reset and insert into the limiting groove 433 of the rotating cavity 432. During the resetting process of the limiting plate 446, the limiting shaft 447 drives the top plate 445 to reset via the rotating block 443, thereby resetting the top rod 426. When the driving component 413 drives the rotating plate 421 to rotate via the external spline shaft 415, the rotating plate 421 can stretch the spring 45 via the fixing block 46. This allows the air sweeping plate 325 to automatically rotate to its previous state before being closed when the heating mechanism 10 is subsequently turned on, thanks to the resetting force of the spring 45, without needing to readjust the angle of the air sweeping plate 325 again.

[0068] Working principle: When the angle of the sweeping plate 325 needs to be adjusted, the telescopic component 411 drives the driving component 413 to move via the mounting plate 412. The driving component 413 drives the outer spline shaft 415 to move into the inner spline groove 424 via the rotating shaft 414. At the same time, the end of the inner spline groove 424 pushes the push rod 426 upward. During the upward movement of the push rod 426, it can push the top plate 445 in the sliding seat 441 upward. At the same time, the top plate 445 pushes the rotating block 443 to rotate around the rotating shaft 442. During the rotation of the rotating block 443, it can drive the limiting plate 446 downward via the limiting shaft 447, thereby allowing the limiting plate 446 to move out of the limiting groove 433 of the rotating cavity 432, while keeping the spring 449 in a stretched state. At this time, when the driving component 413 drives the rotating plate 421 to rotate via the external spline shaft 415, the rotating plate 421 can drive the sliding seat 441 to slide on the inner wall of the rotating cavity 432 via the second spring 45 on the fixed block 46. During the rotation of the rotating plate 421, the rotating plate 421 drives the sweeping plate 325 to rotate around the fixed shaft 324 via the second hinge plate 327 on the hinge shaft 422, so as to adjust the angle of the sweeping plate 325, thereby adjusting the up and down air direction of the air outlet on the fixed frame 31.

[0069] When the air outlet of the fixed frame 31 needs to be closed, the telescopic component 411 drives the drive component 413 to reset via the mounting plate 412. The drive component 413 drives the external spline shaft 415 to reset via the rotating shaft 414, at which point the external spline shaft 415 disengages from the push rod 426. At this time, the force of the spring 449 resetting can drive the limiting plate 446 to reset and insert into the limiting groove 433 of the rotating cavity 432. At this time, the drive component 413 drives the rotating plate 421 to rotate via the external spline shaft 415, so as to rotate the sweeping plate 325 to the vertical position, thereby closing the air outlet of the fixed frame 31. After the sweeping plate 325 is rotated to the vertical position, the drive component 413 is de-energized, and the brake pad in the drive component 413 locks the drive shaft on it. During the rotation of the rotating plate 421, the spring 45 can be stretched by the fixing block 46 so that when the heating mechanism 10 is turned on, the air sweeping plate 325 can automatically rotate to the state before it was turned off, without the need to adjust the angle of the air sweeping plate 325 again.

[0070] When the drive unit 413 is energized, the brake pads in the drive unit 413 are released. At this time, the force of the spring 45 returning to its original position can drive the rotating plate 421 to rotate through the fixed block 46, so that the sweeping plate 325 rotates to the angle before it is closed.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
