Description

Gas alarm for improving use safety of user Technical Field The application relates to the technical field of gas alarms, in particular to a gas alarm for improving the use safety of a user. Background The gas used as clean energy is increasingly popular in urban residents, accidents caused by gas leakage are also gradually increased, and related departments pay attention to gas safety gradually, so that the installation and the use of a household gas leakage alarm are promoted. The basic function of the gas alarm is to monitor the gas concentration in the environment, send out an audible and visual alarm when the preset monitored concentration is exceeded, and control the gas pipeline to be cut off. When no concentration exceeds standard and no other faults occur in the environment, only the power indicator lamp is lighted. In order to ensure the normal use of the alarm, self-checking test and maintenance should be performed regularly. Although the gas alarm is gradually popularized, most of the gas alarm belongs to passive installation, people are not paid attention to the thought consciousness of gas safety, even the existence of the gas alarm is ignored, self-checking test and basic maintenance are not carried out regularly according to requirements, and the gas alarm is focused until the alarm gives an alarm or goes wrong to give out audible and visual warning. Because the user does not pay attention to the habit of the gas alarm at ordinary times, even the power failure of the power supply of the gas alarm can not be found, the gas alarm is in an unprotected state for a long time, and the potential safety hazard is greatly improved. Disclosure of utility model In order to reduce the potential safety hazard of the use of the gas alarm, the application provides a gas alarm for improving the use safety of a user, which adopts the following technical scheme: a gas alarm for improving user safety in use, comprising: the digital display screen is used for displaying clock information and gas concentration; the display driving circuit is used for driving the digital display screen to display; the microprocessor MCU is electrically connected with a power interface and a key inside the gas alarm body and a communication serial port of a processor of the gas alarm body, and is also electrically connected with the display driving circuit and the digital display screen and used for displaying the read RTC information and gas concentration inside the gas alarm body on the digital display screen. According to the technical scheme, on one hand, the digital display screen can be used for clock display, so that a person cooking in a kitchen can observe a clock on the gas alarm conveniently when observing time is necessary to pay attention to the product, on the other hand, when the gas alarm body detects that concentration data exists in the environment, the digital display screen is switched to gas concentration display, when the user checks the gas alarm body habitually, the abnormal phenomenon of the gas concentration can be found in advance, dangers can be found conveniently in time, and therefore potential safety hazards of the gas alarm are reduced. Optionally, the gas alarm further comprises: the loudspeaker is used for outputting voice prompt information; and the voice driving circuit is electrically connected with the microprocessor MCU and the loudspeaker and is used for driving the loudspeaker to output the voice prompt information. By adopting the technical scheme, voice prompt information can be sent out at fixed time intervals, such as 18:00 a day, for example, please press the self-checking key and pay attention to observing all display lamps and the sent detection sound | when you have a regular self-checking, and the gas alarm periodically reminds to carry out self-checking test, so that people can develop a habit of paying attention to gas safety, and the potential safety hazard of using the gas alarm is further reduced. Optionally, the digital display screen displays two colors of green and red, wherein green represents clock information and red represents gas concentration. By adopting the technical scheme, the user can quickly and conveniently identify whether the display content of the digital display screen is clock information or gas concentration information. Optionally, the voice driving circuit and the digital display screen power port are electrically connected with the power interface of the gas alarm body.
