[0036] See also Figures 1 to 4 , the embodiment of the air quality monitor of the present invention is suitable for being arranged on a setting plane 9 (see Figure 6 ), comprising a shell unit 1, a sensing unit 2, a processing unit 3, and a transmission unit 4.

[0037] The housing unit 1 comprises a bottom wall 11, a surrounding wall 12 extending upward from the periphery of the bottom wall 11 along a vertical direction Z, a top wall 13 connected to the surrounding wall 12 and spaced apart from the bottom wall 11 in the vertical direction Z, two heat insulating walls 14 spaced apart along a length direction X perpendicular to the vertical direction Z, a plurality of reinforcing rib groups 15, two closing walls 16, and two reinforcing rib groups 17 (see Figure 5 ), and two filling pieces 18.

[0038] See also Figure 2 , Figures 4 to 6 The heat insulating wall 14 extends along a width direction Y perpendicular to the length direction X and is connected to the surrounding wall 12. One of the heat insulating walls 14 defines a sensing space 101 together with the bottom wall 11, the surrounding wall 12 and the top wall 13. Another heat insulating wall 14 defines a processing space 102 together with the bottom wall 11, the surrounding wall 12 and the top wall 13. The heat insulating walls 14 define a heat insulating space 103 passing through the bottom wall 11 and the top wall 13.

[0039] The bottom wall 11 has two setting parts 111 spaced apart along the length direction X and connected to the setting plane 9, a raised part 112 connected to the setting part 111 and spaced apart from the setting plane 9 in the up-down direction Z, and a bottom heat insulation hole 110 connecting the outside with the heat insulation space 103 and formed in the raised part 112. By setting the raised part 112 spaced apart from the setting plane 9, the outside air can more easily enter the heat insulation space 103 through the bottom heat insulation hole 110, so the heat insulation effect of the heat insulation space 103 can be improved.

[0040] In this embodiment, the bottom wall 11 is detachably connected to the surrounding wall 12, which is convenient for assembly. However, in other variations, the bottom wall 11 and the surrounding wall 12 may also be formed in one piece.

[0041] The surrounding wall 12 has a plurality of heat dissipation grooves 121 extending from the outer surface to the inner surface and extending along the length direction X. The heat dissipation grooves 121 are arranged at intervals along the up-down direction Z. The heat dissipation grooves 121 can increase the surface area of ​​the surrounding wall 12, thereby improving the heat dissipation effect and preventing heat from accumulating inside the housing unit 1.

[0042] The top wall 13 has a plurality of top insulation holes 130 for connecting the outside with the insulation space 103. By connecting the outside through the insulation space 103 and separating the sensing space 101 from the processing space 102, the heat generated by the processing space 102 can be prevented from being transferred to the sensing space 101.

[0043] See also Figures 7 to 10 Each of the heat-insulating walls 14 has a heat-insulating bottom surface 141 adjacent to the bottom wall 11, two recessed portions 142 extending upward from the heat-insulating bottom surface 141 along the vertical direction Z, and a through hole 140 extending from one side to the other side along the length direction X. The through holes 140 are respectively formed in the recessed portions 142 and extend upward from the heat-insulating bottom surface 141 along the vertical direction Z.

[0044] See also Figure 4 , Figure 5 , Figure 8 and Fig.10 Each of the reinforcing rib groups 15 has two first reinforcing ribs 151 extending relatively from the heat insulating wall 14 along the length direction X, and a second reinforcing rib 152 connected to the first reinforcing ribs 151. By providing the reinforcing rib group 15, the structural strength between the heat insulating walls 14 can be improved, and the housing unit 1 can be prevented from being compressed and deformed toward the heat insulating space 103 when being pressed, which has the advantage of improving durability.

[0045] See also Figure 8 , Fig.10 and Fig.11 In this embodiment, one of the second reinforcing ribs 152 is adjacent to the top wall 13, and the other second reinforcing ribs 152 are adjacent to the bottom wall 11. By arranging at least one of the second reinforcing ribs 152 adjacent to the top wall 13, and arranging at least another of the second reinforcing ribs 152 adjacent to the bottom wall 11, the housing unit 1 is unlikely to be deformed and damaged by being folded in half at both ends along the length direction X, so the structural strength can be further improved, and the housing unit 1 has the advantage of being more durable. In other variations, the number of the second reinforcing ribs 152 in each reinforcing rib group 15 may be two or more, but is not limited thereto.

[0046] It should be supplemented that, in the present embodiment, the top heat insulation hole 130 is separated by the second reinforcing rib 152 arranged adjacent to the top wall 13, but in other variations, the number of the top heat insulation holes 130 can also be one, three, or more than three, without being limited thereto, as long as they can be used to connect the insulation space 103 with the outside world.

[0047] See also Figures 13 to 15 In other variations, the reinforcing rib group 15 (see Figure 8 and Fig.10 ) is replaced by a plurality of reinforcing walls 153 connected to the heat insulating wall 14 along the length direction X. The reinforcing walls 153 are arranged at intervals along the width direction Y and extend downward from the top wall 13 along the up-down direction Z. The reinforcing walls 153 divide the heat insulating space 103 into a plurality of subspaces 105 that are not interconnected. In this way, the structural strength can be further improved, and it has the advantage of being more durable.

[0048] See also Figure 2 , Figure 5 , Figure 8 and Fig.12 , the enclosed wall 16 is spaced from the surrounding wall 12 along the width direction Y. Each of the enclosed walls 16 is connected to the heat insulating wall 14, and together with the heat insulating wall 14, the top wall 13 and the surrounding wall 12, defines a closed space 104. The heat insulating wall 14 and the enclosed wall 16 together define the heat insulating space 103. One of the through holes 140 connects the enclosed space 104 with the sensing space 101. Another of the through holes 140 connects the enclosed space 104 with the processing space 102.

[0049] In other variations, the through holes 140 may also be respectively configured as follows: one of the through holes 140 connects the sensing space 101 and the thermal insulation space 103 , and another of the through holes 140 connects the processing space 102 and the thermal insulation space 103 .

[0050] In this embodiment, the heat insulating wall 14 and the closed wall 16 extend from the bottom heat insulating hole 110 along the vertical direction Z out of the outer surface of the bottom wall 11, but in other variations, the heat insulating bottom surface 141 of the heat insulating wall 14 and the bottom surface of the closed wall 16 below the vertical direction Z may also abut against the inner surface of the bottom wall 11, and the bottom wall 11 and the adjacent second reinforcing ribs 152 jointly define a plurality of bottom heat insulating holes 110. The number of the bottom heat insulating holes 110 may also be two or more, but is not limited thereto.

[0051] See also Figure 5 , Figure 7 , Fig. 9 and Fig.12 Each of the reinforcing rib groups 17 is located in one of the enclosed spaces 104 and connects the surrounding wall 12, the top wall 13, the heat insulating wall 14 and one of the enclosed walls 16. The structural strength of the housing unit 1 can be improved by providing the reinforcing rib groups 17, and the housing unit 1 can be prevented from being compressed and deformed toward the enclosed space 104 when under pressure, thereby having the advantage of improving durability.

[0052] In this embodiment, the surrounding wall 12, the top wall 13, the heat insulating wall 14, the reinforcing rib group 15, the closing wall 16 and the reinforcing rib group 17 are formed as one piece, so the structural strength is better.

[0053] The housing unit 1 further includes a plurality of air holes 120 formed in the surrounding wall 12 and connecting the outside with the sensing space 101. In other variations, the air holes 120 may also be formed in the bottom wall 11 or the top wall 13, as long as they can connect the outside with the sensing space 101.

[0054] See also Figures 9 to 12 The sensing unit 2 is disposed in the sensing space 101 and can sense the external air through the air hole 120 to generate a sensing signal.

[0055] The processing unit 3 is disposed in the processing space 102 and is signal-connected to the sensing unit 2 , and can generate air quality data according to the sensing signal.

[0056] The transmission unit 4 includes a transmission line group 41 electrically connecting the sensing unit 2 and the processing unit 3, and a heat-insulating adhesive 42. The transmission line group 41 passes through the through hole 140. The heat-insulating adhesive 42 is filled between the through hole 140 and the transmission line group 41.

[0057] In this embodiment, the through hole 140 is disposed between one of the closed walls 16 and the surrounding wall 12. Therefore, when installing the transmission line group 41, the housing unit 1 can be installed as follows: Fig.10 The device is inverted as shown, and the transmission line group 41 is connected to the sensing unit 2 and the processing unit 3 through the through hole 140, and then the heat insulation glue 42 is filled and the filling piece 18 is placed to complete the installation, so it has the advantages of easy assembly and reduced production cost. At the same time, the filling piece 18 abuts against the recessed part 142 and closes the closed space 104. The heat insulation glue 42 and the filling piece 18 can prevent the heat in the processing space 102 from flowing to the sensing space 101 through the closed wall 16 and the surrounding wall 12.

[0058] In other variations, the sensing unit 2 and the processing unit 3 can also transmit the sensing signal wirelessly without providing the transmission unit 4 and the through hole 140. However, in this embodiment, the sensing unit 2 and the processing unit 3 are electrically connected by the transmission line set 41, which is less likely to cause the sensing unit 2 and the processing unit 3 to generate additional heat during the signal transmission process, and therefore, the sensing accuracy is higher.

[0059] In this embodiment, in order to prevent dust from entering the interior and to remind the user of the functions of the air quality monitor, the housing unit 1 may also optionally include a nameplate 19 attached to the top wall 13. The user can remove the nameplate 19 and open the top insulation hole 130 to improve the insulation effect. However, as long as the bottom insulation hole 110 (see FIG. Figure 2 ) is connected to the outside world by at least one of the top insulation holes 130 so that the outside air can enter the insulation space 103 and prevent the heat in the processing space 102 from flowing to the sensing space 101.

[0060] Through the above description, the advantages of the above embodiments are summarized as follows:

[0061] (1) By defining the heat-insulating space 103 connected to the outside world through the heat-insulating wall 14, an air gap can be blocked between the processing space 102 and the sensing space 101, making it difficult for the waste heat generated by the processing unit 3 to be transmitted to the sensing space 101. Therefore, the sensing of the sensing unit 2 can be prevented from being disturbed by the waste heat, which has the advantage of improving the sensing accuracy.

[0062] (2) By providing the transmission line group 41, the additional heat generated during the signal transmission between the sensing unit 2 and the processing unit 3 is reduced. At the same time, the heat in the processing space 102 is blocked by the heat insulating glue 42 and the filler 18 from flowing to the sensing space 101 through the closed wall 16 and the surrounding wall 12, thereby improving the sensing accuracy of the sensing unit 2.

[0063] (3) By disposing the through hole 140 between one of the closed walls 16 and the surrounding wall 12, extending the through hole 140 upward from the heat insulating bottom surface 141 along the up-down direction Z, and disposing the bottom wall 11 to be detachably connected to the surrounding wall 12, it has the advantages of easy assembly and reduced production costs.

[0064] (4) By providing the heat dissipation slot 121 to improve the heat dissipation effect, and providing the raised portion 112 to allow the outside air to more easily enter the heat insulation space 103 through the bottom heat insulation hole 110, the influence of waste heat on the sensing of the sensing unit 2 can be further reduced, thereby achieving higher sensing accuracy.

[0065] (5) By providing the reinforcing rib group 15 and the reinforcing rib group 17, and by forming the surrounding wall 12, the top wall 13, the heat insulating wall 14, the reinforcing rib group 15, the closed wall 16 and the reinforcing rib group 17 into an integral form, the structural strength and durability can be improved. In other variations, the structural strength and durability can be further improved by providing the reinforcing wall 153.

[0066] The above descriptions are merely embodiments of the present invention and should not be used to limit the scope of the present invention. That is, any simple equivalent changes and modifications made according to the claims and description of the present invention still fall within the scope of the present invention.
