Intelligent coal gas switch

Abstract

The invention discloses an intelligent coal gas switch which is characterized in that the coal gas switch is a sensor unit which transmits acquisition information to a single-chip microcomputer. Meanwhile, the single-chip microcomputer is connected with an alarm and a motor; and the single-chip microcomputer judges the flame combustion state according to the switch state information and the gas concentration information collected by the sensor unit and controls the motor to drive the coal gas switch to turn off automatically and to carry out alarming. The intelligent coal gas switch is high in portability, convenient to dismount and suitable for the majority of cookers in the markets, has the features of convenient usage and intelligent induction, and can carry out real-time gas leakage detection; the intelligent coal gas switch can be time-set and controllable, and a plurality of modes can be set; the intelligent coal gas switch has the features of an alarm device and a long-distance notification device, so that when emergency situation occurs or a gas stove is not turned off for a long time, a user can be informed in real time; the coal gas switch is internally provided with the motor, so that a rotary knob can be automatically switched back to enable the switch to be in the closing state; and the coal gas switch is internally provided a local area network module, so that the switch can be linked with a current intelligent home system.

Description

technical field [0001] The invention relates to the technical improvement of the gas cooker, in particular to an intelligent gas switch. Background technique [0002] Along with popularizing of gas stove, the safety of gas stove has become an important aspect that people pay close attention to. Accidents caused by gas leakage and forgetting to turn off the gas stove are not uncommon every year. Therefore improving the use safety of gas range is an important work. [0003] The safety measures applied by gas stoves on the market can solve some potential safety hazards, but they all have shortcomings in varying degrees. For the device that turns off the switch at a fixed time, there is basically no prompting device, and it will be closed no matter what the situation is when the time is reached, which requires the user to have a very accurate judgment on the time to heat the object, which indirectly increases the difficulty of use; in addition, the Most of these devices use m...

Problems solved by technology

[0003] The safety measures applied to the gas stoves on the market can solve some safety hazards, but they all have different degrees of shortcomings.

For the device that turns off the switch at a fixed time, there is basically no prompting device, and it will be closed no matter what the situation is when the time is reached, which requires the user to have a very accurate judgment on the time to heat the object, which indirectly increases the difficulty of use; in addition, the Most of these devices use mechanical devices, the structure is more complicated, the installation and maintenance are more troublesome, and the versatility and portability are poor.

As for the gas leakage detection device, its technology is relatively mature, but the performance of the device is relatively simple, it can only detect the gas concentration, and it is powerless to deal with phenomena such as over-combustion
