DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a technical solution: a formaldehyde concentration detector that is easy to carry, including a detector body 1, a display screen 2 and a detection head 4. The display screen 2 is embedded in the front of the detector body 1, and an operation button 3 is arranged below the detector body 1 near the display screen 2. The detection head 4 is arranged on the top of the detector body 1, and a protective component 5 is arranged on the outside of the detection head 4. The protective component 5 includes a protective frame 501, a limit stopper 502, a connecting plate 503, a magnetic seat 504, a guide rod 505, a first spring 506 and a connecting block 507. The protective frame 501 is sleeved on the outside of the detection head 4, and the bottom of the protective frame 501 is connected to the upper end surface of the detector body 1, and the limit stoppers 502 are inserted through both sides of the protective frame 501.

[0021] A connecting plate 503 is connected to the lower part of the inner wall of the limit stop seat 502, and a magnetic seat 504 is arranged on the inner side of the connecting plate 503; a guide rod 505 is passed through the lower part of the protective frame 501 near the limit stop seat 502, and the two ends of the guide rod 505 are respectively connected to the connecting plate 503 and the inner wall of the limit stop seat 502; a first spring 506 is sleeved on the outer side of the guide rod 505, and the two ends of the first spring 506 are respectively connected to the connecting plate 503 and the inner wall of the protective frame 501, a connecting block 507 is arranged in the middle part of the inner wall of the protective frame 501, the connecting block 507 is made of metal iron, and the connecting block 507 and the magnetic seat 504 are connected by suction, the guide rods 505 are symmetrically distributed about the center line of the connecting plate 503, and the connecting plate 503 forms a telescopic structure with the protective frame 501 through the first spring 506.

[0022] In specific implementation, when the detector body 1 is in use, the limit stops 502 at both ends of the protection frame 501 are pulled outward, and the pulled limit stops 502 drive the lower connecting plate 503 and the connected guide rod 505 to move outward synchronously. As the connecting plate 503 moves outward, the first spring 506 sleeved on the outer side of the guide rod 505 is squeezed until the limit stop 502 is pulled outward to the limit position. At this time, the connecting plate 503 is attached and connected to the connecting block 507 through the magnetic seat 504 on the inner wall, so that the detection head 4 inside the protection frame 501 is exposed to the outside. After use, the user pulls the limit stop 5 02 is pushed inward, so that the limit stop seat 502 moves inward. As the limit stop seat 502 moves, the limit stop seat 502 will drive the magnetic seat 504 on the connecting plate 503 to separate from the connecting block 507. At this time, the connecting plate 503 and the limit stop seat 502 that are not limited by external force can automatically reset inward to the initial position through the elastic force of the first spring 506, so that the two limit stops 502 are blocked on the outside of the detection head 4. By arranging the limit stop seat 502 and the protective frame 501 on the outside of the detection head 4 to cooperate with each other, the detection head 4 exposed to the outside can be shielded and protected, thereby facilitating the carrying of the formaldehyde concentration detector.

[0024] During specific implementation, when conducting formaldehyde concentration detection, the staff pushes the limit seat 9 outward, and the pushed limit seat 9 drives the connected connecting pin 11 to move outward synchronously. As the limit seat 9 moves, the limit seat 9 squeezes the second spring 12 sleeved on the outside of the connecting pin 11 until the limit seat 9 is pushed to the limit position. At this time, the distance between the limit seat 9 and the protrusion 8 is the largest, and the staff can insert their fingers into the interior of the connecting sleeve 7, and then stop pushing the limit seat 9. At this time, the limit seat 9 that is not squeezed by external force can automatically reset inward by the elastic force of the second spring 12 until the groove 10 on the inner side of the limit seat 9 can fit on the outside of the user's finger. The friction between the user's hand and the detector body 1 is increased by the rubber limit seat 9 and the protrusion 8, and the limit seat 9 limits the hand, thereby making the formaldehyde concentration detector more stable when held in the hand.
