[0029] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0030] like Figure 1-4 As shown, an indoor formaldehyde detection device includes a detector 5, and also includes:

[0031] Support cylinder 1, a top rod 11 is provided inside the support cylinder 1, and a clamping unit 4 of clamping detector 5 is provided at one end of the top rod 11;

[0032] Leg 2, which is set at one end of support cylinder 1;

[0033] The height adjustment unit 3 is located at the other end of the support cylinder 1. The height adjustment unit 3 includes a support plate 33, a motor 34, and a drive wheel 32 located at the output end of the motor 34. An adjustment wheel 35 that meshes with the drive wheel 32 is rotatably arranged on the support plate 33. The adjustment wheel 35 is threadedly connected to the top rod 11.

[0034] Specifically, during formaldehyde testing, the indoor environment needs to be sealed, and the temperature should be maintained between 25-30℃. Before sealing, the detector 5 is placed at the detection point in the room. The components on the support cylinder 1 are spread open, and then the detector 5 is fixed onto the clamping unit 4. At this time, the motor 34 controls the rotation of the drive wheel 32. Since the adjusting wheel 35 meshes with the drive wheel 32 and the adjusting wheel 35 is threadedly connected to the top rod 11, the height of the top rod 11 is adjusted by rotating the drive wheel 32, so that the height of the detector 5 is adjusted to 50cm. Then the room is sealed for 12 hours. After sealing, the detector 5 is started to detect the formaldehyde in the room. After the detection at this height is completed, the motor 34 runs to adjust the height of the detector 5 to 80cm, 120cm and 150cm respectively for detection. The corresponding detection values ​​are recorded and compared to improve the detection accuracy. The model of the motor 34 is: MHMF042L1U4-1116.

[0035] As a further embodiment of this utility model, a chuck 12 is provided on the support cylinder 1, a support plate 33 is fixed on the chuck 12, a protective cover 31 is provided on the support plate 33, and the support plate 33 is fixed to the chuck 12 by bolts. The chuck 12 plays the role of limiting support to improve the stability of the output of the motor 34. The protective cover 31 covers the drive wheel 32 and the adjusting wheel 35 to protect the parts in the height adjustment unit 3.

[0036] As a further embodiment of this utility model, the clamping unit 4 includes a rotating seat 44 and an adjusting rod 46. An angle adjusting block 47 is rotatably disposed on the rotating seat 44, and a screw 43 is disposed on the angle adjusting block 47. A clamping block 42 for clamping the detector 5 is disposed on the screw 43. The adjusting rod 46 is disposed on one side of the rotating seat 44 and cooperates with the angle adjusting block 47. There are two sets of clamping blocks 42. When the screw 43 rotates, it drives the two sets of clamping blocks 42 to slide relative to each other on the angle adjusting block 47 until the clamping block 42 contacts the detector 5 and clamps and fixes the detector 5. A pad 41 is disposed on the angle adjusting block 47. When the detector 5 is placed on the angle adjusting block 47, the pad 41 limits and positions the detector 5 to improve the fixing effect of the detector 5.

[0037] As a further embodiment of this utility model, a cover plate 45 is provided on the rotating seat 44, and a first transmission wheel 441 and a second transmission wheel 442 are respectively provided on the cover plate 45. The first transmission wheel 441 meshes with the second transmission wheel 442, and the first transmission wheel 441 is engaged with the adjusting rod 46. An internal gear 441 is rotatably provided inside the rotating seat 44 and engages with the angle adjusting block 47. The internal gear 441 meshes with the second transmission wheel 442. Rotating the adjusting rod 46 causes the first transmission wheel 441 to rotate, causing the second transmission wheel 442 to mesh with the internal gear 441 and rotate synchronously. This causes the angle adjusting block 47 to rotate on the rotating seat 44 to adjust the placement angle of the detector 5, ensuring that the detector 5 is fixed in a suitable position, thereby improving the detection accuracy.

[0038] As a further embodiment provided by this utility model, the number of teeth of the first transmission wheel 441 is less than the number of teeth of the second transmission wheel 442, so as to perform deceleration motion and improve the rotation accuracy of the angle adjustment block 47.

[0039] As a further embodiment of this utility model, a fitting block 422 is slidably disposed on the clamping block 42, and a spring 421 is disposed between the fitting block 422 and the clamping block 42. The fitting block 422 is a rubber block. The spring 421 and the fitting block 422 are used to improve the fixing effect on the detector 5 and at the same time reduce the damage to the surface of the detector 5 during the clamping process.

[0040] As a further embodiment of this utility model, the tripod 2 includes a locking member 26, a fixing plate 21, and a main support 22 rotatably mounted on the fixing plate 21. A support rod 24 is slidably mounted on the main support 22, and a foot 25 is mounted on one end of the support rod 24. The fixing plate 21 is mounted on the support cylinder 1. The locking member 26 is threadedly connected to the main support 22 and abuts against the support. When the detection device is placed at an indoor detection point, multiple main supports 22 rotate on the fixing plate 21, while the support rod 24 slides in the groove 23 within the main support 22 to adjust the initial height of the detection device. Then, the locking member 26 is rotated so that the locking member 26 abuts against the support rod 24, thereby fixing the support rod 24 to the main support 22 and completing the separation of the tripod 2 from the support cylinder 1.

[0041] As a further embodiment of this utility model, a support plate 28 is provided on the support cylinder 1, the support plate 28 has a groove, a second locking rod 29 is provided in the groove, a first locking rod 20 is provided on the main bracket 22, and a side rod 27 is provided between the first locking rod 20 and the second locking rod 29. When the main bracket 22 is separated from the support cylinder 1, the side rod 27 is locked onto the first locking rod 20 and the second locking rod 29 to improve the support of the support cylinder 1 and improve the stability of the device during the testing process.

[0042] As a further embodiment of this utility model, a magnetic block 281 is provided in the groove. The magnetic block 281 is attracted to the main support 22. The width of the main support 22 is adapted to the width of the groove. When the main support 22 rotates toward the axis of the support cylinder 1, the main support 22 will be inserted into the groove and attracted to the magnetic block 281, thereby fixing the main support 22 and reducing the space required for the device to be placed, so as to facilitate carrying and placement. Furthermore, there are two sets of second locking rods 29 on the main support 22. After the test is completed, the side rod 27 is engaged with the two locking rods so that the side rod 27 is placed close to the main support 22.

[0043] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
