Problems solved by technology

[0003] The existing formaldehyde detector alarm device consumes too much power due to the defects in its system design. If the alarm device is powered only by the formaldehyde detector's own power supply, its overall running time will not exceed 3 hours, so it is convenient Greatly affected the normal operation of the formaldehyde detector
In addition, the stability of the system operation of the alarm system is poor, and it is easy to be damaged during operation, which increases the cost of product use and increases the burden on users

Abstract

The invention discloses a double-enhancement alarm system of a formaldehyde detector. The alarm system comprises a signal trigger chip U1, a capacitor C4, a capacitor C2, a power input circuit, a trigger alarm circuit, a chip enhancement circuit and a drive enhancement circuit. The power consumption of the double-enhancement alarm system of the formaldehyde detector is reduced, the operating stability of the system is improved, then the use value and the use effect of a product are greatly improved, and the service life of the product is better prolonged.

Description

technical field [0001] The invention belongs to the field of household safety, and specifically refers to a double-enhanced alarm system for a formaldehyde detector. Background technique [0002] With the improvement of people's quality of life, the decoration of houses has become more and more luxurious, and today's various furniture, paints and decorations will release harmful substances such as formaldehyde in use, and in order to better monitor indoor The concentration of various harmful substances, usually newly renovated houses generally install multi-functional formaldehyde detectors to detect various harmful substances, and the existing multi-functional formaldehyde detectors can only simply measure the concentration of harmful substances If it is necessary to remind the occupants in time, it is also necessary to install an alarm device on it. [0003] The existing formaldehyde detector alarm device consumes too much power due to the defects in its system design. If...
