[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] Thus, a feature indicated in this specification is intended to illustrate one of the features of one embodiment of the present invention, rather than implying that every embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other, not explicitly described, combinations. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0019] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments:

[0020] refer to Figure 1-3 A portable formaldehyde detection device includes a formaldehyde detection body 1. A plurality of gas sensing holes 14 are provided on the front of the formaldehyde detection body 1 at equal intervals. Trapezoidal plates 2 are fixedly connected at the upper and lower ends of the formaldehyde detection body 1. Limiting holes 3 are provided on the left and right sides of the trapezoidal plate 2. A limiting rod 6 is slidably sleeved in the limiting hole 3. An ABS shell 9 is slidably sleeved on the surface of the formaldehyde detection body 1. Grooves 4 are provided on the upper and lower sides of the ABS shell 9. A spring 16 is fixedly connected in the groove 4. One end of the spring 16 is fixedly connected to a slide plate 7. A first mounting port is provided on the front of the formaldehyde detection body 1. A display screen 12 is fixedly connected in the first mounting port.

[0021] By providing the gas sensing hole 14 , formaldehyde is allowed to enter the formaldehyde detection body 1 for detection.

[0022] By providing the limiting hole 3 and the limiting rod 6 , when the limiting rod 6 is inserted into the limiting hole 3 , the installation of the ABS housing 9 is completed.

[0023] Furthermore, two ABS shells 9 are provided, wherein the upper end surface of one ABS shell 9 is fixedly connected to the first pull bar 8 , and the upper end surface of the other ABS shell 9 is fixedly connected to the second pull bar 11 .

[0024] The first pull bar 8 and the second pull bar 11 are provided to facilitate movement of the device.

[0025] Furthermore, the left side of the first pull strip 8 is overlapped with the right side of the second pull strip 11 , and an alarm 13 is fixedly installed on the front of the formaldehyde detection body 1 .

[0026] By setting the alarm 13, when the formaldehyde detection concentration exceeds the standard, the alarm 13 will sound in time to remind the user.

[0027] Furthermore, a magnet 15 is fixedly connected to the back of the formaldehyde detection body 1 , and four magnets 15 are provided.

[0028] By providing the magnet 15, when the magnet 15 is in contact with the metal object, the installation of the device is achieved.

[0029] Furthermore, a second installation opening is formed on the inner walls of the two ABS shells 9 , and a first dustproof net 10 is fixedly connected to the second installation opening.

[0030] By providing the first dustproof net 10 , dust can be prevented from entering the formaldehyde detection body 1 while the formaldehyde detection body 1 can dissipate heat normally.

[0031] Furthermore, heat dissipation holes are provided on both the left and right sides of the formaldehyde detection body 1 , and the side of the slide plate 7 facing away from the spring 16 is fixedly connected to one end of the limiting rod 6 .

[0032] The working principle of the present utility model is as follows: when in use, the device is carried to the area where formaldehyde is detected. If there is metal, the formaldehyde detection body 1 can be temporarily installed on the wall by fitting with the magnet 15. If there is no metal, it can be placed directly on the ground. At the same time, formaldehyde is detected in the gas sensing hole 14. The data after the detection is completed will be fed back to the display screen 12, which is convenient for the user to view and judge. When the formaldehyde data exceeds the standard, the alarm 13 will sound the alarm in time to prompt. Under the action of the ABS shell 9, the device has a good protective effect on the surface of the formaldehyde detection body 1. When the ABS shell 9 and the first dustproof net 10 need to be cleaned, the slide plate 7 is pushed in the direction of the spring 16 to squeeze them, so that the limit rod 6 is disengaged from the limit hole 3. The user can then move the ABS shell 9 outward for easy cleaning, avoiding clogging of the first dustproof net 10 and affecting the normal heat dissipation effect in the formaldehyde detection body 1. And under the action of the first pull strip 8 and the second pull strip 11, it is convenient to take the formaldehyde detection body 1.

[0033] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
