Description

TECHNICAL FIELD

[0002] Heating equipment refers to equipment used in specific scenarios (such as homes, office spaces, etc.) that generates heat through fuel burning, electrical energy conversion, or heat transfer to meet the heating needs of indoor or specific spaces. It includes central heating systems, air conditioners, electric heaters, and other types. The core function is to create a warm and comfortable environment for users through different heat transfer principles (such as radiation, convection, and heat conduction). It is suitable for different space sizes, usage requirements, and energy conditions, with wide applicability and diverse selection space. Currently, the air outlet of heating equipment usually uses the opening and closing of louver blades to adjust.

The device includes a ventilation pipe and an adjusting mechanism. The lower end of the ventilation pipe is connected to the upper end of the air outlet pipe. The adjusting mechanism includes a chain wheel one, a chain wheel two, a chain, and a wind deflector. The wind deflector is connected to the left and right walls of the ventilation pipe through a rotating shaft. The chain wheel two is located at the right end of the rotating shaft and in the inner cavity of the right wall of the ventilation pipe. The chain wheel one is connected to the inner cavity of the right wall of the ventilation pipe through a rotating shaft. The chain wheel one and the chain wheel two are connected by a chain.

DETAILED DESCRIPTION

[0035] The embodiments of the application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the application, and cannot be understood as a limitation of the application.

[0036] As Figures 1 to 11 shown, the heating equipment ventilation air conditioning system of the application includes a heating mechanism 10, a shell 20 and a blowing mechanism 30. The shell 20 is installed on one side of the heating mechanism 10, and the number of the blowing mechanism 30 is two, and the two blowing mechanisms 30 are symmetrically arranged on the top of one side of the shell 20. The interior of each of the two blowing mechanisms 30 is provided with an adjusting mechanism one 40 and an adjusting mechanism two 50.

[0037] The hot air blown by the heating mechanism 10 enters the shell 20 and is blown out by the blowing mechanism 30. During blowing, the blowing direction of the blowing mechanism 30 is adjusted by the adjusting mechanism one 40 and the adjusting mechanism two 50. When the heating mechanism 10 is closed, the air outlet of the blowing mechanism 30 is closed by the adjusting mechanism one 40 and the adjusting mechanism two 50. When the heating mechanism 10 is opened, the blowing direction of the blowing mechanism 30 can be adjusted to the position before the last closing by the adjusting mechanism one 40 and the adjusting mechanism two 50.

[0038] As shown in Figures 1 to 3 , the blowing mechanism 30 comprises a fixed frame 31, a sweeping component one 32 and a sweeping component two 33. The fixed frame 31 is installed at the top of one side of the shell 20, and the fixed frame 31 is connected with the heating mechanism 10. The side of the fixed frame 31 opposite to the heating mechanism 10 has a blowing port, and the inner wall of the blowing port of the fixed frame 31 has two vertical plates extending to the inside of the fixed frame 31. The sweeping component one 32 is arranged in the air outlet of the fixed frame 31, and the sweeping component one 32 is hinged with the adjusting mechanism one 40. The inside of the fixed frame 31 is provided with a horizontal plate, and the horizontal plate in the fixed frame 31 is arranged close to the sweeping component one 32. The sweeping component two 33 and the adjusting mechanism two 50 are arranged on the horizontal plate of the fixed frame 31, and the sweeping component two 33 is hinged with the adjusting mechanism two 50. The sweeping component one 32 and the sweeping component two 33 have the same structure, and the sweeping component one 32 is vertically arranged in the inside of the fixed frame 31, and the sweeping component two 33 is horizontally arranged in the inside of the fixed frame 31.

[0039] When the heating mechanism 10 is opened, the adjusting mechanism one 40 can drive the sweeping component one 32 to rotate to change the up-down blowing direction of the blowing port on the fixed frame 31, and at the same time, the adjusting mechanism two 50 can drive the sweeping component two 33 to rotate to change the left-right blowing direction of the blowing port on the fixed frame 31. When the heating mechanism 10 is opened again after being closed, the adjusting mechanism one 40 and the adjusting mechanism two 50 can respectively drive the sweeping component one 32 and the sweeping component two 33 to return to the position before the last closing, without the need for further adjustment, which is convenient to use.

[0040] As shown in Figures 2 to 4 , the sweeping component one 32 comprises a movable plate 321, a sweeping piece and a hinged plate two 327. The movable plate 321 is movably arranged on one side of one of the vertical plates of the fixed frame 31, one end of the hinged plate two 327 is hinged on one side of the bottom of the movable plate 321, and the other end of the hinged plate two 327 is hinged on the adjusting mechanism one 40. The sweeping piece is rotatably connected between the two vertical plates of the fixed frame 31, and the number of the sweeping pieces is multiple, and the multiple sweeping pieces are vertically and equidistantly distributed.

[0041] The air sweeping component comprises a rotating rod 322, a hinged 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 two sides of the air sweeping plate 325, and the air sweeping plate 325 is arranged between the two vertical plates of the fixed frame 31. One end of the fixed shaft 324 penetrates one of the vertical plates of the fixed frame 31 and extends to the outside of the vertical plate, one end of the hinged plate 323 is installed on one end of the fixed shaft 324, and the other end of the hinged plate 323 is hinged to one end of the rotating rod 322, and the other end of the rotating rod 322 is rotatably connected to the movable plate 321.

[0042] When the angle of the air sweeping plate 325 is adjusted, the adjusting mechanism 40 can drive the movable plate 321 to move through the hinged plate 327, and the movable plate 321 can drive the air sweeping plate 325 to rotate around the fixed shaft 324 through the hinged plate 323 on the rotating rod 322, so as to adjust the angle of the air sweeping plate 325, thereby adjusting the up and down air direction of the air outlet on the fixed frame 31.

[0043] When it is necessary to close the air outlet of the fixed frame 31, the adjusting mechanism 40 drives the air sweeping plate 325 to rotate to a vertical state through the hinged plate 327, so as to close the air outlet of the fixed frame 31 and prevent dust and other sundries from entering the fixed frame 31.

[0044] The adjusting principle of the air sweeping component 33 is the same as that of the air sweeping component 32, and will not be described here.

[0045] As shown in Figures 2 to 5 and Figure 7 The adjusting mechanism 40 comprises a driving assembly 41, a rotating assembly 42, a mounting assembly 43, a limiting assembly 44, a spring 45 and a fixed block 46. The driving assembly 41 is arranged on one side of the inner wall of the fixed frame 31, the mounting assembly 43 is located on one side of the driving assembly 41 and is mounted on the inner wall of the fixed frame 31. The rotating assembly 42 is rotatably arranged on the inner side of the mounting assembly 43, and the driving assembly 41 is inserted into one end of the rotating assembly 42, and the other end edge of the rotating assembly 42 is hinged to the hinged plate 327. The limiting assembly 44 is located on the outer side of the rotating assembly 42 and is slidably arranged on the inner side of the mounting assembly 43, and in the initial state, the limiting assembly 44 is inserted into the mounting assembly 43. The fixed block 46 is mounted on the outer side of the rotating assembly 42 and is arranged in a spaced manner with the limiting assembly 44, and the two ends of the spring 45 are respectively mounted on the limiting assembly 44 and the fixed block 46.

[0046] When the angle of the air sweeping plate 325 needs to be adjusted, the driving assembly 41 moves inside the rotating assembly 42 and pushes the limiting assembly 44, so that the limiting assembly 44 and the mounting assembly 43 change from the plug-in state to the sliding state. Then the driving assembly 41 drives the rotating assembly 42 to rotate inside the mounting assembly 43. In the process of rotation, the rotating assembly 42 drives the air sweeping plate 325 to rotate through the second hinge plate 327, and the limiting assembly 44 slides inside the mounting assembly 43 through the second spring 45.

[0047] When the air outlet of the fixed frame 31 needs to be closed, the driving assembly 41 resets in the rotating assembly 42, and at this time the limiting assembly 44 and the mounting assembly 43 change from the sliding state to the plug-in state. Then, the driving assembly 41 drives the air sweeping plate 325 to change to the vertical state through the second hinge plate 327 on the rotating assembly 42, and the second spring 45 is in a stretched state.

[0048] When the air outlet of the fixed frame 31 is closed by the air sweeping plate 325, the driving assembly 41 is self-locked, thereby locking the rotating assembly 42. When the air outlet of the fixed frame 31 needs to be opened again, the driving assembly 41 is unlocked, so that the rotating assembly 42 can rotate. At this time, the force of the reset of the second spring 45 drives the rotating assembly 42 to rotate through the fixed block 46, and the rotating assembly 42 drives the air sweeping plate 325 to rotate to the angle before the last closing through the second hinge plate 327, so that the angle of the air sweeping plate 325 does not need to be adjusted again, and the use is more convenient.

[0049] As shown in Figure 3 and Figure 6 , the driving assembly 41 includes a telescopic part 411, a mounting plate 412, a driving part 413, a rotating shaft 414 and an outer spline shaft 415. The telescopic part 411 and the driving part 413 are both mounted on one side of the mounting plate 412, and the movable end of the telescopic part 411 penetrates through the mounting plate 412 and is mounted on one side of the inner wall of the fixed frame 31. In this embodiment, the telescopic part 411 is a telescopic motor, and in other embodiments, the telescopic part 411 can be a pneumatic cylinder or a hydraulic cylinder. One end of the rotating shaft 414 is mounted on the driving shaft of the driving part 413, and one end of the outer spline shaft 415 is mounted on the other end of the rotating shaft 414. The outer spline shaft 415 is plugged into the rotating assembly 42, and the other end of the outer spline shaft 415 has an arc surface. In this embodiment, the driving part 413 is a stepping motor with brake pads. It should be noted that when the driving part 413 is powered off, the brake pads on the driving part 413 lock the driving shaft, and when the driving part 413 is powered on, the brake pads on the driving part 413 unlock the driving shaft, so that the driving shaft on the driving part 413 can rotate under the action of an external force.

[0050] When it is necessary to adjust the angle of the air-sweeping plate 325, the telescopic part 411 drives the driving part 413 to move through the mounting plate 412, the driving part 413 drives the outer spline shaft 415 to further extend into the rotating assembly 42 through the rotating shaft 414, so that the limiting assembly 44 and the mounting assembly 43 are changed from the plug-in state to the sliding state, then the driving part 413 drives the rotating assembly 42 to rotate through the outer spline shaft 415, the rotating assembly 42 drives the air-sweeping plate 325 to rotate through the hinged plate two 327, so as to adjust the angle of the air-sweeping plate 325.

[0051] As shown in Figures 3 to 8 , the rotating assembly 42 comprises a rotating plate 421, a hinged shaft 422, a top rod 426 and a limiting ring 427. The rotating plate 421 is rotationally connected in the mounting assembly 43, and a through hole 423 is formed at the center of the rotating plate 421. The hinged shaft 422 is installed at one end edge of the rotating plate 421, one end of the hinged plate two 327 is hinged with the hinged shaft 422, and an inner spline groove 424 is formed at the other end of the rotating plate 421 and communicates with the through hole 423.

The limiting ring 427 is installed at the outer side of the top rod 426 and slidingly connected with the inner side of the sliding groove 425. In the initial state, the outer spline shaft 415 is inserted in the inner spline groove 424, and the end of the outer spline shaft 415 is close to the bottom end of the top rod 426.

[0052] When it is necessary to unlock the limiting assembly 44 and the mounting assembly 43, the telescopic part 411 drives the driving part 413 to move through the mounting plate 412, the driving part 413 drives the outer spline shaft 415 to move inwardly into the inner spline groove 424, while the end of the inner spline groove 424 pushes the top rod 426 to move upwardly, so that the top rod 426 can push the limiting assembly 44, at this time, the limiting assembly 44 and the mounting assembly 43 are changed from the plug-in state to the sliding state.

[0053] As shown in Figure 3 and Figure 7 , the mounting assembly 43 comprises a fixed plate 431, a rotating cavity 432 and a limiting groove 433.

The rotating plate 421 is rotationally connected in the inner side of the rotating cavity 432, the fixed block 46 is installed at the outer side of the rotating plate 421, and the limiting assembly 44 is slidingly connected on the inner wall of the rotating cavity 432. The limiting groove 433 is in a plurality of numbers, and the plurality of limiting grooves 433 are arranged in an annular array on the inner wall of the rotating cavity 432, and the limiting assembly 44 can be inserted into the limiting groove 433.

[0054] When the limiting assembly 44 needs to be inserted into the limiting slot 433, the telescopic piece 411 drives the driving piece 413 to reset through the mounting plate 412, and the driving piece 413 drives the outer spline shaft 415 to reset through the rotating shaft 414, at this time, the outer spline shaft 415 is separated from the jacking rod 426, so as to reset the jacking rod 426. When the jacking rod 426 is reset, the limiting assembly 44 is inserted into the limiting slot 433 of the rotating cavity 432, so as to fix the limiting assembly 44.

[0055] As shown in Figures 7 to 11 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 I 449.

[0057] The structure and principle of the adjusting mechanism II 50 are the same as those of the above-mentioned adjusting mechanism I 40, and will not be described here.

[0058] When the telescopic part 411 drives the driving part 413 to move through the mounting plate 412, the driving part 413 drives the outer spline shaft 415 to move to the inside of the inner spline groove 424 through the rotating shaft 414, which makes the end of the inner spline groove 424 push the top rod 426 to move upwards. In the process of moving upwards, the top rod 426 can push the top plate 445 in the sliding seat 441 to move upwards, and at the same time, the top plate 445 drives the rotating block 443 to rotate around the rotating shaft 442. In the process of rotating, the rotating block 443 can drive the limiting plate 446 to move downwards through the limiting shaft 447, so as to make the limiting plate 446 move out of the limiting groove 433 of the rotating cavity 432, and at the same time, make the spring I 449 in the stretched state. At this time, when the driving part 413 drives the rotating plate 421 to rotate through 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 through the spring II 45 on the fixed block 46.

[0059] When the telescopic part 411 drives the driving part 413 to reset through the mounting plate 412, the driving part 413 drives the outer spline shaft 415 to reset through the rotating shaft 414, at this time, the outer spline shaft 415 is separated from the top rod 426. At this time, the force of the spring I 449 in the reset state can drive the limiting plate 446 to reset and be inserted in the limiting groove 433 of the rotating cavity 432. In the process of resetting, the limiting shaft 447 can drive the top plate 445 to reset through the rotating block 443, so as to make the top rod 426 reset. At this time, when the driving part 413 drives the rotating plate 421 to rotate through the outer spline shaft 415, the rotating plate 421 can stretch the spring II 45 through the fixed block 46, so as to make the sweeping plate 325 automatically rotate to the state before the last time of closing through the force of the spring II 45 in the reset state, without the need to adjust the angle of the sweeping plate 325 again.

[0060] When the angle of the air-sweeping plate 325 needs to be adjusted, the telescopic part 411 drives the driving part 413 to move through the mounting plate 412, the driving part 413 drives the outer spline shaft 415 to move into the inner spline groove 424 through the rotating shaft 414, and the end of the inner spline groove 424 pushes the top rod 426 to move upwards. In the process of moving upwards, the top rod 426 can push the top plate 445 in the sliding seat 441 to move upwards, and the top plate 445 pushes the rotating block 443 to rotate around the rotating shaft 442. In the process of rotating, the rotating block 443 can drive the limiting plate 446 to move downwards through the limiting shaft 447, so that the limiting plate 446 moves out of the limiting groove 433 of the rotating cavity 432, and the spring I 449 is in a stretched state. At this time, when the driving part 413 drives the rotating plate 421 to rotate through 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 through the spring II 45 on the fixed block 46. In the process of rotating, the rotating plate 421 drives the air-sweeping plate 325 to rotate around the fixed shaft 324 through the hinged plate II 327 on the hinged shaft 422, so as to adjust the angle of the air-sweeping plate 325, thereby adjusting the up and down direction of the air outlet on the fixed frame 31.

[0061] When the air outlet of the fixed frame 31 needs to be closed, the telescopic part 411 drives the driving part 413 to reset through the mounting plate 412, the driving part 413 resets through the rotating shaft 414, and the outer spline shaft 415 is disengaged from the top rod 426 at this time. At this time, the force of the spring I 449 in the reset state can drive the limiting plate 446 to reset and be inserted into the limiting groove 433 of the rotating cavity 432, and the driving part 413 drives the rotating plate 421 to rotate through the outer spline shaft 415 at this time, so as to rotate the air-sweeping plate 325 to the vertical state, thereby closing the air outlet of the fixed frame 31. When the air-sweeping plate 325 is rotated to the vertical state, the driving part 413 is powered off, and the brake disc in the driving part 413 locks the driving shaft thereon. In the process of rotating, the rotating plate 421 can stretch the spring II 45 through the fixed block 46, so that the air-sweeping plate 325 can automatically rotate to the state before being closed last time without the need to adjust the angle of the air-sweeping plate 325 again when the heating mechanism 10 is opened subsequently.

[0062] When the driving part 413 is powered on, the brake disc in the driving part 413 is released, and the force of the spring II 45 in the reset state can drive the rotating plate 421 to rotate through the fixed block 46, so that the air-sweeping plate 325 is rotated to the angle before being closed.
