Description

Technical Field

[0001] The utility model relates to the technical field of formaldehyde detection, in particular to a formaldehyde fixed-point and timed detection device. Background Art

[0002] Formaldehyde is a colorless, pungent organic compound commonly found in building materials, furniture, decorations, cleaning products, etc. Long-term exposure to an environment containing high concentrations of formaldehyde may cause harm to human health. The formaldehyde fixed-point timing detection device is a professional device used to continuously monitor the formaldehyde concentration in the air at a specific time and place.

[0003] The existing formaldehyde detection method is that a person brings a formaldehyde detector with a bracket to the place where formaldehyde detection is required, then opens the bracket, stands the formaldehyde detector on the ground, and then detects formaldehyde in the air. The formaldehyde detector with a bracket is large in size and occupies a large area, which is inconvenient to detect formaldehyde in different places, resulting in poor flexibility in the use of the formaldehyde detector.

[0004] Therefore, it is necessary to design a formaldehyde fixed-point and timing detection device that can be clamped and fixed on a desktop or cabinet, and can also be used standing on the ground, so as to adapt to formaldehyde detection in different places and improve the flexibility of the use of the device. Utility Model Content

[0006] A formaldehyde fixed-point and timed detection device comprises a formaldehyde detector, a sliding rod, a support frame, an adjusting screw, a clamping mechanism and an opening mechanism. The upper part of the support frame is slidably connected with the sliding rod, the sliding rod is connected with the formaldehyde detector, the upper front side of the support frame is threadedly connected with the adjusting screw, the adjusting screw is in contact with the sliding rod, the support frame is provided with a clamping mechanism for fixing the device, and the formaldehyde detector is provided with an opening mechanism for detecting formaldehyde.

[0007] Further explanation: There is a button on the formaldehyde detector.

[0008] Further description, a handle is connected to the front side of the adjusting screw.

[0009] Further description, the clamping mechanism includes a support plate, a screw and a sliding frame, the support plate is connected to the middle of the support frame, the support plate is rotatably connected to the screw, the sliding frame is threadedly connected to the screw, and the sliding frame is slidably connected to the support frame.

[0010] Further description, it also includes a knob, and the screw rod is connected with the knob.

[0011] Further description: the opening mechanism includes a support cover, an intermittent motor, a rotating cover and a filter. The formaldehyde detector is connected to the support cover, the front of the support cover is connected to the intermittent motor, the output shaft of the intermittent motor is connected to the rotating cover, the rotating cover is in contact with the support cover, and the filter is connected to the top of the support cover.

[0012] The utility model has the following advantages: 1. The utility model clamps the desktop or cabinet between the sliding frame and the supporting frame, and then rotates the screw by turning the knob, thereby driving the sliding frame to move downward, and then clamping the desktop or cabinet, so that the device can be clamped and fixed on the desktop or cabinet, and can also be used standing on the ground, which is convenient for adapting to formaldehyde detection in different places and improving the flexibility of the use of the device.

[0013] 2. When the formaldehyde detector of the utility model is used for a long time, dust will fall on the filter net. When the intermittent motor drives the rotating cover to close, the rotating cover will sweep out the dust or garbage accumulated on the filter net, thereby cleaning the dust and keeping the formaldehyde detector clean, preventing dust from sticking to the detection head and affecting the use of the formaldehyde detector, and extending the service life of the formaldehyde detector.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] A formaldehyde fixed-point and timed detection device, such as Figure 1-Figure 5 As shown, it includes a formaldehyde detector 1, a slide bar 2, a support frame 3, an adjusting screw 4, a clamping mechanism 5 and an opening mechanism 6. The upper part of the support frame 3 is slidably connected to the slide bar 2, and the slide bar 2 is connected to the formaldehyde detector 1. The formaldehyde detector 1 is provided with a button for easy operation of the formaldehyde detector 1. The front side of the upper part of the support frame 3 is connected to the adjusting screw 4 through a thread. The adjusting screw 4 is in contact with the slide bar 2. The front side of the adjusting screw 4 is connected to a handle for easy hand-gripping and rotation of the adjusting screw 4. The support frame 3 is provided with a clamping mechanism 5 for fixing the device, and the formaldehyde detector 1 is provided with an opening mechanism 6 for detecting formaldehyde.

[0022] like Figure 1 and Figure 3 As shown, the clamping mechanism 5 includes a support plate 51, a knob 52, a screw 53 and a sliding frame 54. The support plate 51 is connected to the middle of the support frame 3. The support plate 51 is rotatably connected to the screw 53. The screw 53 is connected to the knob 52, which is convenient for hand-gripping and rotating the screw 53. The sliding frame 54 is threadedly connected to the screw 53, and the sliding frame 54 is slidably connected to the support frame 3.

[0023] like Figure 1 , Figure 4 and Figure 5 As shown, the opening mechanism 6 includes a support cover 61, an intermittent motor 62, a rotating cover 63 and a filter 64. The formaldehyde detector 1 is connected to the support cover 61, the front of the support cover 61 is connected to the intermittent motor 62, the output shaft of the intermittent motor 62 is connected to the rotating cover 63, the rotating cover 63 is in contact with the support cover 61, and the top of the support cover 61 is connected to the filter 64.

[0024] When formaldehyde detection is needed, the device can be used. The adjusting screw 4 is turned through the handle to disengage the adjusting screw 4 from the slide bar 2, and then the slide bar 2 is moved to adjust the height of the formaldehyde detector 1. After adjusting to a suitable height, the adjusting screw 4 is turned in the opposite direction to make the adjusting screw 4 contact with the slide bar 2, and then the slide bar 2 is fixed. Then the support frame 3 is in contact with the desktop or cabinet, so that the desktop or cabinet is stuck between the slide frame 54 and the support frame 3. Then, the screw 53 is turned by the knob 52 to rotate, thereby driving the slide frame 54 to move downward, and then the desktop or cabinet is clamped. In this way, the device can be clamped and fixed on the desktop or cabinet, and can also be used standing on the ground, which is convenient for adapting to formaldehyde detection in different places and improving the device. The formaldehyde detector 1 has the advantages of flexibility in use and can realize fixed-point detection. After the fixing is completed, the formaldehyde detector 1 is opened by starting the button, and then the intermittent motor 62 on the support cover 61 is started. The intermittent motor 62 drives the rotating cover 63 to rotate and open, and then the formaldehyde is detected. The intermittent motor 62 is used to realize timed detection of formaldehyde, and the detection data will be recorded in the formaldehyde detector 1. When the formaldehyde detector 1 is used for a long time, dust will fall on the filter 64. When the rotating cover 63 is closed, the rotating cover 63 will sweep out the dust or garbage accumulated on the filter 64, so as to clean the dust, keep the formaldehyde detector 1 clean, prevent dust from sticking to the detection head and affecting the use of the formaldehyde detector 1, and extend the service life of the formaldehyde detector 1.
