Hood control system capable of detecting carbon monoxide concentration

Abstract

The invention discloses a hood control system capable of detecting carbon monoxide concentration. The system comprises a carbon monoxide concentration detection module, a buzzer, a display module and a fan driving module, wherein the carbon monoxide concentration detection module, the buzzer, the display module and the fan driving module are connected with a single chip computer. The carbon monoxide concentration detection module comprises a carbon monoxide sensor and a current amplifying circuit. The output end of the carbon monoxide sensor is connected with the input end of the current amplifying circuit. The output end of the current amplifying circuit is connected with the input pin with an AD conversion function in the single chip microcomputer. According to the invention, the carbon monoxide concentration in the kitchen environment of a user is detected in real time by the action of the carbon monoxide detection module; when the carbon monoxide concentration exceeds an allowable value, the buzzer sends an alarm to remind the user to take further measures; and if a hood is already running, the system can automatically increase the rotation speed of a fan to discharge carbon monoxide to prevent carbon monoxide poisoning.

Description

technical field [0001] The invention belongs to the technical field of range hoods, and in particular relates to a range hood control system capable of detecting the concentration of carbon monoxide. Background technique [0002] There are currently three types of gas in the home: [0003] 1. Natural gas, the main component is methane; [0004] 2. Liquefied petroleum gas, the main components are propane and butane; [0005] 3. Water gas, the main components are hydrogen and carbon monoxide. [0006] Among them, when natural gas and liquefied petroleum gas are not fully burned, carbon monoxide gas will be produced, and dihydrate gas itself contains carbon monoxide gas, and leakage will occur if it is not well preserved. [0007] On the one hand, the main hazard of carbon monoxide is to combine with hemoglobin in the human body, so that it can no longer combine with oxygen and poison people, which can lead to coma or even death in severe cases; Collision with certain objec...

Problems solved by technology

[0006] Among them, when natural gas and liquefied petroleum gas are not fully burned, carbon monoxide gas will be produced, and dihydrate gas itself contains carbon monoxide gas, and leakage will occur if it is not well preserved.

[0007] On the one hand, the main hazard of carbon monoxide is to combine with hemoglobin in the human body, so that it can no longer combine with oxygen and poison people, which can lead to coma or even death in severe cases; Collision with certain objects and explosion causing casualties and property damage

[0008] At present, there are some instruments for detecting carbon monoxide concentration on the market. Due to the limitations of their quality, volume and ease of use, they are generally widely used in places such as mines and automobiles to detect air safety and quality, and are rarely used in family life.

Also, since CO can come from combustion as well as from leaks, CO testing must be done on an ongoing basis
