The utility model has the beneficial effects that: visual window is formed on the casing through the effect of through-hole and transparent cover plate, places the pilot lamp in visual window simultaneously to set up steam detection circuit board in the casing, can make the pilot lamp discolour when the inside steam that exists of casing, whether the colour change that the pilot lamp was observed to the visual window of accessible judges in the casing has steam.
Description of the drawings:
fig. 1 is a schematic view of the structure of a housing with an internal moisture detection function.
The figures are numbered: 1. a screw; 2. pressing a plate; 3. a seal ring; 4. an indicator light; 5. a transparent cover plate; 6. a housing; 7. the water vapor detection circuit board.
The specific implementation mode is as follows:
the present invention will be described in detail below with reference to the accompanying drawings.
As shown in the attached drawing 1, the shell with the internal water vapor detection function comprises a shell 6, and further comprises a transparent cover plate 5, a water vapor detection circuit board 7 and an indicator lamp 4, wherein a through hole is formed in the shell 6, the transparent cover plate 5 is hermetically arranged on the through hole of the shell 6, the water vapor detection circuit board 7 is arranged in the shell 6, the indicator lamp 4 is arranged between the transparent cover plate 5, and the water vapor detection circuit board 7 is electrically connected with the indicator lamp 4.
Form a visual window through the effect of through-hole and transparent cover 5 on casing 6, place pilot lamp 4 and steam detection circuit board 7 (be used for the response to detect steam) simultaneously in visual window, can be sensed by steam detection circuit board 7 when 6 inside steam that exist of casing, steam detection circuit board 7 can give information transfer to pilot lamp 4, thereby arouse the 4 colour changes of pilot lamp, whether the colour change that accessible visual window observed pilot lamp 4 has steam in judging casing 6.
The moisture detection circuit board 7 is a circuit board with a sensor and power supply.
As shown in the attached figure 1, the device further comprises a pressing plate 2, the pressing plate 2 is fixedly arranged in the loading shell 6, the pressing plate 2 is located at an opening on one side of the through hole, and the indicator light 4 is clamped between the transparent cover plate 5 and the pressing plate 2.
The pressing plate 2 has the function of clamping the indicator lamp 4 together with the transparent cover plate 5, so that the indicator lamp 4 can be better fixed.
