AI Technical Summary
The existing formaldehyde detection device may cause detection errors due to aging and poor contact after a long period of time, and cannot be reminded. Moreover, during maintenance, staff are prone to inhaling a large amount of formaldehyde, which reduces the accuracy and safety of the detection.
A formaldehyde exceeding the standard reminder device for indoor environment detection is designed, including the body and purification plate, which improves detection accuracy and safety through dual detection structure and photocatalytic reaction. The device uses the dual detection structure of the formaldehyde detector and the contact switch to ensure that the alarm will emit an alarm when the formaldehyde exceeds the standard, and absorb the formaldehyde through the activated carbon packet. The extrusion and placement of the plate drive the touch block to touch the contact switch, and continuously issue an alarm. At the same time, the purification plate produces a photocatalytic reaction through ultraviolet irradiation, decomposes formaldehyde into water and carbon dioxide, and discharges the device.
Through dual detection structure and photocatalytic reaction, the accuracy and safety of formaldehyde detection are improved, ensuring that when formaldehyde exceeds the standard, the alarm can be issued in time, and the formaldehyde can be effectively decomposed and discharged, protecting the safety of staff.

[0002] Formaldehyde (HCHO) is a gas with a pungent odor, usually in the form of an aqueous solution. The recognized main hazards of formaldehyde are sensitization, mutagenesis and carcinogenesis to organisms, as well as irritation to the skin. Formaldehyde has currently become the most important factor in indoor air pollution, and formaldehyde detection devices are needed to detect formaldehyde content.
[0003] The existing detection devices rely on a single detector for detection. After long-term use, the detector may fail to provide reminders due to aging, poor contact, etc., which reduces the detection accuracy. Most of the existing detection devices only have detection functions and cannot filter and purify formaldehyde. Long-term use will cause a large amount of formaldehyde to be adsorbed inside the device. When the device is opened for maintenance, it will cause the staff to inhale a large amount of formaldehyde, reducing safety. For this reason, we propose a formaldehyde excess reminder device for indoor environment detection. Utility Model Content
