Description

Technical Field

[0001] The utility model relates to the technical field of detection alarms, in particular to an infrared photoelectric smoke temperature detection alarm. Background Art

[0002] A detection alarm is a device used to detect specific environmental changes or abnormal conditions, and issue a warning signal when preset conditions are detected. They play an important role in many fields such as security, fire prevention, and environmental monitoring. Depending on the detection target, alarms can be divided into many types, mainly including: Smoke detection alarms: specially used to detect the smoke concentration in the air. Once the set threshold is reached, the alarm will sound to promptly notify people of possible fire risks so that quick measures can be taken. This type of alarm is usually used in residences, offices, schools, hospitals and other places. Temperature detection alarms: monitor temperature changes in the environment or specific objects, and activate the alarm when the temperature exceeds the safe range, which helps prevent fires or other accidents caused by high temperatures.

[0003] In the existing technology, some detection alarms can only use smoke or temperature alone to judge whether a fire has occurred. However, the smoke exhaled by some smokers when smoking can easily cause the smoke-type detection alarm to make an incorrect judgment, thereby causing it to falsely report a fire, which is very inconvenient. Some detection alarms are powered by batteries internally, but it is difficult to replace the batteries in these detection alarms, and it is difficult to detect whether the batteries are fully charged, which is very disadvantageous for users. Utility Model Content

Compared with the prior art, the infrared photoelectric smoke and temperature detection alarm is provided with a main board, which is electrically connected to the photoelectric smoke detector, the main board is electrically connected to the infrared temperature detector, and the main board is electrically connected to the buzzer. The photoelectric smoke detector is provided with a first threshold value for lower smoke sensitivity, i.e., low smoke concentration, and a second threshold value for higher smoke sensitivity, i.e., high smoke concentration. The infrared temperature detector is provided with a first threshold value for lower temperature sensitivity, and a second threshold value for higher temperature sensitivity. When the photoelectric smoke detector alone reaches the first threshold value, it transmits an electrical signal to the main board, and the buzzer does not work.

[0031] By providing first and second chambers 1 and 3, and by making them from fluoroplastics, fluoroplastics possess numerous significant advantages, leading to their widespread application in various industries. The following are their key advantages: Chemical inertness: Fluoroplastics are highly resistant to most chemicals and are unaffected by virtually all common chemicals and solvents, making them particularly suitable for environments requiring corrosion-resistant materials, such as the chemical and pharmaceutical industries. Wide temperature range: Fluoroplastics maintain their performance over a very wide temperature range, from -80°C to 250°C, making them suitable for use in extreme conditions, from cryogenic to high temperatures. Excellent electrical insulation: Fluoroplastics have a high resistivity, making them excellent electrical insulating materials for use in the electrical and electronics industries. Low friction coefficient: Fluoroplastics, particularly polytetrafluoroethylene (PTFE), have an extremely low coefficient of friction, exhibiting excellent self-lubrication properties that reduce wear and are suitable for use in bearings, seals, and other applications. Non-stick surface: Fluoroplastic surfaces resist adhesion to other substances, making them easy to clean. They are widely used in anti-stick coatings for cookware and industrial equipment. Weather resistance: Fluoroplastics are highly resistant to environmental factors, such as UV rays and ozone, ensuring long-term performance during outdoor use. Wear resistance: It has good wear resistance and can maintain a long service life even under harsh conditions. Food safety: Some fluoroplastics meet food safety standards and can be used in the food processing and packaging industries. Ease of processing: Although the processing requires special techniques, such as controlling the appropriate temperature and pressure, fluoroplastics can be processed through various methods such as extrusion, injection molding, and pressing. Long-term stability: Fluoroplastic products can maintain unchanged performance for many years under proper use and maintenance.
