[0006] The top cover has two top cover half holes and two half hole extension holes. The top cover half holes and the half hole extension holes are connected. The top cover half holes and the half hole extension holes are distributed sequentially along the lower edge of part of the top cover.

[0007] The base has two base half-holes, which are distributed sequentially along the upper edge of the base. The base half-holes are directly opposite the top cover half-hole. Two volatile substances sensors are respectively built into the top cover half-hole. The top cover half-hole, the half-hole extension hole, and the base half-hole together form a gas channel.

[0008] As a preferred technical solution to the above technical solutions, the mobile volatile organic compound monitoring device further includes a first circuit board and a second circuit board.

Detailed Implementation

[0022] This utility model discloses a mobile volatile matter monitoring device. The following description, in conjunction with a preferred embodiment (Example 1), refers to the accompanying drawings. Figures 1 to 8 The specific embodiments of this utility model will be further described below.

[0023] See attached diagram. Figures 1 to 8 , Figures 1 to 4 Mobile volatile organic compound (VOC) monitoring devices are shown from different perspectives. Figure 5 and Figure 6 The top cover is shown from different perspectives. Figure 7 A mobile volatile organic compound (VOC) monitoring device without a top cover is shown. Figure 8 The base is shown.

[0024] Example 1.

[0025] Preferably, the mobile volatile organic compound (VOC) monitoring device includes a top cover 100, a base 200, and multiple VOC sensors 330 (preferably five VOC sensors 330). The top cover 100 and the base 200 are snap-fitted together, wherein:

[0026] The top cover 100 has two top cover half holes 101 and two half hole extension holes 102. The top cover half holes 101 and the half hole extension holes 102 are connected. The top cover half holes 101 and the half hole extension holes 102 are distributed sequentially on a portion of the lower edge of the top cover 100.

[0027] The base 200 has two base half-holes 201, which are sequentially distributed along the upper edge of a portion of the base 200. The base half-holes 201 are directly opposite the top cover half-hole 101. Two volatile matter sensors 330 are respectively housed within the top cover half-hole 101 (when the top cover 100 and base 200 are snapped together). The top cover half-hole 101, the half-hole extension hole 102, and the base half-hole 201 together form a gas channel 1, allowing gases such as air containing volatiles to diffuse freely inside and outside the mobile volatile matter monitoring device. In contrast, without the gas channel 1, when gases such as air containing volatiles diffuse to the volatile matter sensors 330, the gas cannot continue to diffuse freely, potentially causing adverse effects such as localized vortices at the volatile matter sensors 330, thus affecting the volatile matter monitoring results.

[0028] The mobile volatile organic compound monitoring device also includes a first circuit board 310 and a second circuit board 320. The first circuit board 310 includes a first circuit board body 311, and the second circuit board 320 includes a second circuit board body 321. There is a gap between the first circuit board body 311 and the second circuit board body 321, so that there is no direct contact between the first circuit board body 311 and the second circuit board body 321, thereby preventing local blockage of the gas channel 1 inside the mobile volatile organic compound monitoring device.

[0029] The top cover 100 also has three round holes 103, and the remaining three volatile matter sensors 330 are respectively built into the round holes 103. It is worth mentioning that a gap is left between the volatile matter sensors 330 and the round holes 103, allowing communication with the gas channel 1.

[0030] The base 200 also has two base square holes 202, which are distributed on opposite sides of the base 200. The base square holes 202 are connected to the gas channel 1.

[0031] The top cover 100 is provided with a top cover grip 110 and a top cover recess 120 integrally formed with the top cover grip 110; making it convenient for users to hold and move the mobile volatile organic compound monitoring device.

[0032] The first circuit board body 311 and the second circuit board body 321 are perpendicularly distributed to each other, so that the second circuit board body 321 is horizontally embedded in the base 200 and the first circuit board body 311 is vertically embedded in the top cover grip 110.

[0033] Specifically, the two volatile matter sensors 330 located in the top cover half-hole 101 are electrically connected to the first circuit board 310, and the three volatile matter sensors 330 located in the top cover round hole 103 are electrically connected to the second circuit board 320. The electrical connection relationship between the volatile matter sensors 330 and the circuit board 320 is prior art.

[0034] It is worth mentioning that the specific structure and other technical features of the volatile substance sensor 330 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0035] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
