Description
Technical Field
The utility model relates to a gas detection sensor especially relates to a gas detection sensor with audible and visual alarm function.
Background
A gas detection sensor is also called a gas sensor, and is a device that converts information such as the composition and concentration of a gas into information that can be used by a person, an instrument, a computer, or the like.
The traditional gas detection sensor generally does not have an integrated acousto-optic alarm function, an external acousto-optic alarm device is connected with the sensor to realize the alarm function, and the traditional gas detection sensor needs to be separately installed and connected during application, so that the traditional gas detection sensor is troublesome; in addition, the existing light alarm mode is a point light source mode, namely, the light of an alarm lamp is not processed, so that the visual effect is not strong enough.
SUMMERY OF THE UTILITY MODEL
An object of the present invention is to provide a gas detection sensor with an audible and visual alarm function for solving the above problems.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
the utility model provides a gaseous detection sensor with audible-visual annunciation function, includes interconnect's circuit mainboard and fixed bolster, still including showing back lid, display circuit board, demonstration protecgulum and facial mask, the lid is installed after showing on the fixed bolster, transparent show the protecgulum with lid connection and general after showing display circuit board presss from both sides and puts between the two, the facial mask cover in show on the protecgulum, display circuit board with circuit mainboard corresponds the connection, install the alarm lamp on the display circuit board, install warning loudspeaker on the circuit mainboard.
Furthermore, in order to realize light alarm in the form of a surface light source, a light scattering device used for scattering alarm light on the display front cover to form the surface light source is arranged on one side surface, corresponding to and close to the alarm light, of the display front cover.
Preferably, in order to achieve a good surface light source effect, the light scattering device is a plurality of transparent convex columns integrally formed with the display front cover, the bottom end size of the transparent convex columns is larger than the top end size, and the plurality of transparent convex columns are arranged in a criss-cross manner. Therefore, the light of the alarm lamp is transmitted and reflected for a plurality of times among the plurality of transparent convex columns and all the transparent convex columns, and finally, an even surface light source is formed in the corresponding area on the transparent front cover.
Specifically, the top surface and the bottom surface of the transparent convex column are both square.
Further, in order to realize the wireless communication function, a wireless communication circuit board is further installed on the circuit main board.
The beneficial effects of the utility model reside in that:
the utility model integrates the light alarm device and the sound alarm device on the gas detection sensor, so that the acousto-optic alarm device is not needed to be additionally installed and the connection circuit is not needed, thereby being convenient and fast; in addition, the point light source of the alarm lamp is converted into the surface light source after being diffused, so that the visual effect of alarming is stronger.
Drawings
Fig. 1 is a perspective view of the gas detection sensor with an audible and visual alarm function according to the present invention before assembly;
fig. 2 is a perspective view of the display front cover of the gas detection sensor with the sound and light alarm function according to the present invention, wherein the view angle is different from that of fig. 1.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1 and 2, the gas detecting sensor with acousto-optic alarm function of the present invention comprises a circuit board 1, a fixing bracket 2, a display rear cover 5, a display circuit board 6, a display front cover 9 and a face film 10, which are connected with each other, the display rear cover 5 is installed on the fixing bracket 2, the transparent display front cover 9 is connected with the display rear cover 5 and clamps the display circuit board 6 between them, the face film 10 covers the display front cover 9, the display circuit board 6 is correspondingly connected with the circuit board 1, the display circuit board 6 is installed with an alarm lamp 7, the circuit board 1 is installed with an alarm horn (invisible but easy to understand in the figure) and a wireless communication circuit board 3, a side surface of the display front cover 9 corresponding to and close to the alarm lamp 7 is provided with an astigmatism device for dispersing the alarm lamp light on the display front cover 9 to form a surface light source, the device is preferably a plurality of transparent convex columns 91 integrally formed with the display front cover 9, the top surface and the bottom surface of the transparent convex columns 91 are square, the side length of the bottom surface is larger than that of the top surface, and the transparent convex columns 91 are arranged in a criss-cross mode. Also shown in fig. 1 is a cover plate 4 that covers the wireless communication circuit board 3. Description of the drawings: the figures show components such as probes, which are conventional configurations of sensors.
As shown in fig. 1 and 2, during the use, if detect that gas concentration exceeds the standard, circuit board 1 then can produce audible and visual alarm signal to respectively with audible alarm signal transmission for warning loudspeaker, give alarm lamp 7 with light alarm signal transmission, the light that alarm lamp 7 sent forms the area source after a plurality of transparent projection 91 dispersion and shows in the corresponding region that shows protecgulum 9, forms strong visual angle effect. The sensor has the acousto-optic alarm function, so that an alarm device does not need to be additionally connected, and the sensor is convenient to mount and apply.
The above-mentioned embodiment is only the preferred embodiment of the present invention, and is not to the limitation of the technical solution of the present invention, as long as the technical solution can be realized on the basis of the above-mentioned embodiment without creative work, all should be regarded as falling into the protection scope of the right of the present invention.
