[0033] like Figures 1-4 As shown, the formaldehyde pollutant concentration detection device disclosed herein may include a box 1, with four fixedly connected casters 11 at the bottom corners of the box 1, and mounting blocks 12 symmetrically fixedly connected to the rear end of the box 1, with a push rod 13 provided between the two mounting blocks 12.

[0034] The top of the housing 1 is provided with a hidden groove 14, the inside of the hidden groove 14 is provided with a movable block 4, and the bottom of the movable block 4 is provided with a drive component.

[0035] The front end of the movable block 4 is provided with a formaldehyde detection head 6, the outer side of the formaldehyde detection head 6 is provided with a shell 61, and the end of the formaldehyde detection head 6 is provided with a second insertion hole 62.

[0036] The inner side of the movable block 4 is provided with an inner groove 41, and the second insertion hole 62 is provided inside the inner groove 41.

[0037] Therefore, by setting a second wiring hole 62, which is fixedly connected to the side of the formaldehyde detection head 6, the formaldehyde detection head 6 can be connected to the cable through the second wiring hole 62, thereby enabling the formaldehyde detection head 6 to communicate with the formaldehyde detector 3. The formaldehyde detection head 6 is an electrochemical sensor that utilizes the oxidation-reduction reaction of formaldehyde gas on the surface of the sensor electrode to generate a small current. The current intensity is proportional to the formaldehyde concentration. After being amplified by the circuit, it is converted into a numerical value, which is suitable for low-concentration detection, such as in a home environment. Results are usually available in 30 seconds to several minutes. The converted numerical signal is then transmitted to the formaldehyde detector 3 through the cable. The moving block 4 can move up and down, thereby enabling the detection of formaldehyde at different heights. When it is necessary to detect different locations or corners where the moving block 4 cannot reach, the formaldehyde detection head 6 can be removed from the side of the moving block 4 to detect the formaldehyde concentration.

[0038] likeFigure 3 As shown, in a preferred embodiment, a fixing block 63 is provided at the top of the inner groove 41 of the formaldehyde detection head 6, a positioning hole 631 is provided on the inner side of the fixing block 63, and a positioning pin 7 is provided on the inner side of the positioning hole 631.

[0039] Therefore, by setting the formaldehyde detection head 6, the formaldehyde detection head 6 can be inserted into the inner side of the inner groove 41. After being fully inserted, the positioning pin 7 can be inserted through the moving block 4 into the inner side of the fixed block 63, thereby limiting the position of the formaldehyde detection head 6. When it is necessary to remove the formaldehyde detection head 6 for use, the positioning pin 7 can be pulled out from the inner side of the fixed block 63, and the casing 61 can be removed from one side of the moving block 4 for use.

[0040] like Figure 2 As shown in this disclosure, the drive assembly includes a drive motor 2, the bottom end of the drive motor 2 is provided with a heat dissipation hole 17, and the output end of the drive motor 2 is threadedly connected to a threaded sleeve 21, which is fixedly connected to the bottom end of the moving block 4.

[0041] Therefore, the front and rear ends of the threaded sleeve 21 are slidably connected to the limiting protrusions 211, and the bottom end of the hidden groove 14 is provided with a limiting hole 19, which is correspondingly set to the threaded sleeve 21 and the limiting protrusions 211.

[0042] Therefore, by setting the limiting protrusion 211, the front and rear ends of the threaded sleeve 21 are slidably connected to the limiting protrusion 211, and the limiting hole 19 is correspondingly set with the threaded sleeve 21 and the limiting protrusion 211. Thus, when the drive motor 2 drives the lead screw at the output end to rotate, it can effectively ensure that the threaded sleeve 21 will not rotate with the rotation of the lead screw, so that the threaded sleeve 21 can move up and down along the limiting hole 19, thereby driving the moving block 4 to move up and down.

[0043] like Figure 2 and Figure 3 As shown in this disclosure, a formaldehyde detector 3 is fixedly connected inside the housing 1. A first plug hole 31 is provided at the rear end of the formaldehyde detector 3, and the first plug hole 31 and the second plug hole 62 are arranged correspondingly to each other.

[0044] Therefore, by setting up a formaldehyde detector 3, which is a common detector on the market, it can quickly detect the formaldehyde concentration. When used in conjunction with the formaldehyde detection head 6, it can effectively detect the indoor formaldehyde concentration.

[0045] like Figure 2 and Figure 4As shown in this disclosure, a fixing rod 5 is fixedly connected to the bottom of the box 1. Two fixing rods 5 are symmetrically arranged, and a guide roller 8 is rotatably arranged between the two fixing rods 5. Two guide rollers 8 are symmetrically arranged vertically and rotatably arranged between the two fixing rods 5. An insert rod 51 is provided in the middle of the fixing rod 5 and is inserted through the inner side of the guide roller 8.

[0046] Therefore, by setting two fixed rods 5 and inserting rods 51, two guide rollers 8 can be rotatably set between the two fixed rods 5. By setting grooves 81, and both guide rollers 8 have grooves 81 in the middle, it is convenient for the cable to move between the two guide rollers 8. The cable is set inside the grooves 81, which improves the convenience of cable movement and limits the movement of the cable. The specific usage is as follows: insert one end of the cable into the first insertion hole 31, and pass the other end of the cable through the two guide rollers 8 on the left side of the fixed rod 5, so that the cable passes out from the right side of the two guide rollers 8 and is inserted into the inner side of the inner groove 41 along the first through groove 18 and the second through groove 42, communicating with and fixing it to the second insertion hole 62. When the formaldehyde detection head 6 is removed for use, it can be easily pulled to slide along the two guide rollers 8 for easy removal. After use, the cable can be pushed back to the inner side of the box 1 along the two guide rollers 8.

[0047] like Figure 2 and Figure 4 As shown in this disclosure, a first through groove 18 is provided at the top of the inner side of the housing 1. The first through groove 18 is provided on one side of the fixed rod 5. A second through groove 42 is provided at the bottom of the moving block 4. The second through groove 42 and the first through groove 18 are provided corresponding to each other.

[0048] Therefore, by setting the first through groove 18 and the second through groove 42, it is convenient for the cable to pass through and to connect with the second insertion hole 62. The second through groove 42 is completely hollow, which makes it convenient for the cable to enter the inner side of the inner groove 41 and be inserted into the second insertion hole 62 for reinforcement, thus improving the use effect. At the same time, the first through groove 18 is set at the bottom of the hidden groove 14, which makes it convenient for the cable to pass through. The cable used to connect the second insertion hole 62 and the first insertion hole 31 is set to be relatively long, which is sufficient for the formaldehyde detection head 6 to move. The cable can be left inside the box 1.

[0049] like Figure 2 and Figure 4 As shown in this disclosure, the front end of the box 1 is provided with a door 15, and the top of the box 1 is provided with a control panel 16. The control panel 16 is electrically connected to the formaldehyde detector 3 through a wire.

[0050] Therefore, by setting up a door 15, one side of the door 15 is connected to the box body 1 by a hinge, which facilitates the protection of the internal components of the box body 1 through the door 15. At the same time, when maintenance is required, maintenance work can be carried out by opening the door 15. By setting up a control panel 16, the control panel 16 is electrically connected to the formaldehyde detector 3 through wires, which facilitates the display of the data information generated by the formaldehyde detector 3 on the control panel 16 for quick observation.

[0051] In practical use, push the box 1 to the room where the formaldehyde concentration needs to be tested, start the drive motor 2 and the formaldehyde detector 3. The drive motor 2 can drive the moving block 4 to move upward. After the height of the moving block 4 is raised, the formaldehyde detection head 6 is fully exposed to detect the formaldehyde in the surrounding environment. The height of the moving block 4 can be continuously adjusted to detect the formaldehyde concentration at different heights. The values ​​can be displayed on the control panel 16 for easy viewing and recording.

[0052] When formaldehyde concentration needs to be detected in corners or locations inaccessible to the movable block 4, the positioning pin 7 is pulled out from the inside of the fixed block 63, the housing 61 is removed from one side of the movable block 4, the formaldehyde detection head 6 is pulled out from the inside of the movable block 4, and the cable is pulled to place the formaldehyde detection head 6 in the cabinet or corner gap to detect the formaldehyde concentration, which effectively improves the convenience of using the device.

[0053] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
