[0022] Embodiment: Please refer to Figures 1 - 8, an energy-saving fresh air system device for a central air conditioner, including a base 1. A support column 11 is arranged at the upper end of the base 1. A sleeve 12 is arranged at the upper end of the support column 11. At the same time, an adjustment block 15 is arranged on the inner wall of the sleeve 12. One end of the adjustment block 15 is provided with a fixed block 13. One end of the fixed block 13 away from the adjustment block 15 is provided with a docking block 14. A positioning component 3 is arranged at the end of the docking block 14 to limit the sensing device through the positioning component 3.

[0023] In this solution, the adjustment block 15 is spherical and is rotatably connected to the inner wall of the sleeve 12. Thus, when the docking block 14 is stressed, it can rotate around the inner wall of the sleeve 12 through the adjustment block 15. At the same time, the lower end of the support column 11 is rotatably connected to the upper end of the base 1, so as to support the sleeve 12 and ensure the overall stability of the entire docking block 14.

[0024] At the same time, the lower end of the docking block 14 is rotatably installed with an adjustment rod 16. The lower end of the adjustment rod 16 is rotatably connected to the upper end of the base 1. Both ends of the adjustment rod 16 are spherical, which is convenient for supporting the docking block 14 when it moves.

[0025] Furthermore, an adjustment component 2 is assembled at the upper end of the base 1 to adjust the position and angle of the sensing device through the adjustment component 2.

[0026] Among them, the adjustment component 2 includes a bottom plate 21 connected to the base 1. A positioning rod 22 is arranged at the upper end of the bottom plate 21. A limit block 23 is arranged at the end of the positioning rod 22. At the same time, a sphere 24 is arranged at one end of the limit block 23 away from the positioning rod 22. The outer surface of the sphere 24 is rotatably connected to the inner wall of the limit block 23.

[0027] In this embodiment, the cross-section of the bottom plate 21 is L-shaped. At the same time, a through hole is opened on one side of the bottom plate 21, and the inner wall of the through hole is slidably connected to the outer surface of the positioning rod 22, so as to limit the positioning rod 22 and provide support for the movement of the positioning rod 22 to ensure that the positioning rod 22 will not fall off during use.

[0028] At the same time, a groove is opened at one end of the limit block 23, and the inner wall of the groove is rotatably connected to the outer surface of the sphere 24. The size of the groove is adjusted by rotating rods on both sides of the limit block 23. One end of the rotating rod penetrates and extends to the other end of the limit block 23, and threads are arranged on the outer surface of the rotating rod to facilitate adjusting the size of the groove.

[0029] Furthermore, an extension rod 25 is arranged on the outer surface of the sphere 24. An activity cylinder 26 is arranged at one end of the extension rod 25 away from the sphere 24. A limiting rod 261 is arranged on the outer surface of the activity cylinder 26. The upper end of the limiting rod 261 is connected to the lower end of the docking block 14.

[0030] Specifically, the cooperation of the sphere 24 and the extension rod 25 can drive the movable cylinder 26 to move, thereby driving the limiting rods 261 arranged on both sides of the movable cylinder 26 to move. Since the upper end of the limiting rod 261 is connected to the docking block 14, when the movable cylinder 26 moves, the docking block 14 can be synchronously driven to adjust, making it applicable to the current scenario, and accurately adjusting the angle of the positioning component 3, so that the detection device installed on the positioning component 3 can accurately monitor the air outlet condition.

[0031] Furthermore, an arc-shaped block 28 is slidably installed on the inner wall of the movable cylinder 26. A plurality of convex blocks 281 are arranged on the outer surface of the arc-shaped block 28, and the plurality of convex blocks 281 are evenly distributed on the outer surface of the arc-shaped block 28.

[0032] A driving member 27 is arranged at one end of the movable cylinder 26 away from the extension rod 25. The output end of the driving member 27 penetrates and extends into the inner cavity of the movable cylinder 26. At the same time, a driving gear 271 is arranged at the output end of the driving member 27. The outer surface of the driving gear 271 meshes with the outer surface of the convex block 281, and the driving gear 271 drives the movable cylinder 26 to move.

[0033] Specifically, the driving member 27 is a device with power output such as a motor and is connected to an external control device. When the driving member 27 is started, the driving gear 271 arranged at its output end is synchronously driven to rotate. Since the outer surface of the driving gear 271 meshes with the outer surface of the convex block 281, when the driving gear 271 rotates, it moves up and down on the arc-shaped block 28 and rotates around the sphere 24.

[0034] When the entire driving member 27 moves, the movable cylinder 26 is synchronously driven to move, so that the detection device is adjusted to be applicable to the current scenario.

[0035] Furthermore, a chute 211 is opened on the upper end of the bottom plate 21 and on the side away from the positioning rod 22. A slider 29 is slidably installed on the inner wall of the chute 211. The upper end of the slider 29 is rotatably connected to the lower end of the arc-shaped block 28.

[0036] Specifically, a telescopic member such as an electric telescopic rod can be arranged in the inner cavity of the chute 211 and is connected to an external control device. The end of the electric telescopic rod is connected to one side of the slider 29. The electric telescopic rod can drive the slider 29 to perform telescopic movement, so that the arc-shaped block 28 arranged on the slider 29 can drive the movable cylinder 26 to make left and right adjustments to meet the detection requirements.

[0037] Further, the positioning component 3 includes a clamping block 31 connected to the docking block 14. At one end of the clamping block 31 away from the docking block 14, baffles 32 are symmetrically arranged. At one end of each of the two baffles 32 away from each other, a power member 33 is provided. At the same time, the output end of the power member 33 penetrates and extends to the other end of the baffle 32.

[0038] In this embodiment, the clamping block 31 is installed on the docking block 14. The power member 33 is a device with a telescopic function such as an electric telescopic rod and is connected to an external control device. At the same time, when the power member 33 is started, it synchronously drives the power rod 34 arranged at its output end to perform telescopic movement.

[0039] Further, at one end of the baffle 32, first movable rods 35 are symmetrically and rotatably installed. At one end of the first movable rod 35 away from the baffle 32, a second movable rod 351 is rotatably installed. At the rotational connection of the first movable rod 35 and the second movable rod 351, a protective rod 36 is provided. At one end of the protective rod 36 away from the first movable rod 35, a power rod 34 is rotatably installed. One end of the power rod 34 away from the protective rod 36 is connected to the output end of the power member 33.

[0040] Specifically, when the power member 33 is started, it drives the power rod 34 to perform telescopic movement, and at the same time drives the protective rod 36 rotatably installed at the end of the power rod 34 to move. Since at one end of the protective rod 36 away from the power rod 34, the first movable rod 35 and the second movable rod 351 are rotatably installed, when the power rod 34 expands and contracts, the distance between one end of the first movable rod 35 and the second movable rod 351 away from each other is adjusted, and then the push plate 37 is synchronously driven to move.

[0041] Further, on both sides of one end of the baffle 32, sliding rods 38 are provided. One end of the push plate 37 is slidably installed on the outer surface of the sliding rod 38 and is rotatably connected to the end of the second movable rod 351. At the middle position of the end of the clamping block 31, a support plate 39 is provided. At one end of the push plate 37 away from the second movable rod 351, a clamping block 371 is provided.

[0042] Specifically, the outer surface of the sliding rod 38 is slidably connected to both ends of the push plate 37, and through the movement of the first movable rod 35 and the second movable rod 351, the distance of the push plate 37 on the sliding rod 38 is synchronously adjusted, so that the push plate 37 is always in the best position.

[0043] When the push plate 37 moves and cooperates with the clamping block 371, the distance between the push plate 37 and the support plate 39 gradually decreases. And on the outer surface of the clamping block 371, there are anti-slip components such as rubber, so that when the clamping block 371 fixes the fixed rod 372, the whole remains stable and avoids the situation of shaking.

[0044] Further, a fixing rod 372 is provided between the clamping block 371 and the support plate 39, and an adjusting plate 373 is provided at the end of the fixing rod 372.

[0045] Specifically, multiple clamping grooves are provided at the end of the adjusting plate 373, and elastic components such as springs are provided on the inner wall of each clamping groove, so that when the detection device is placed in the inner cavity of the clamping groove, the detection device will not shake, thereby ensuring the accuracy of the detection data.

[0046] The control device can select a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller, which is composed of an arithmetic unit, a controller, a memory, input and output devices, etc., and is equivalent to a miniature computer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes more on self-supply (without external hardware) and cost savings. Its greatest advantage is its small size, which can be placed inside the instrument, but its storage capacity is small, the input and output interfaces are simple, and the function consumption is low.

[0047] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
