Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and more specifically, it relates to a smoke and temperature sensing cover with anti-static interference function. Background Technology

[0002] Smoke and temperature alarm devices are commonly installed in enclosed spaces such as shopping malls and office buildings. These devices sense the ambient temperature and smoke in the air, detecting smoke and temperature in the early stages of a fire, issuing timely alarms, and linking with other fire suppression systems to extinguish the fire, thus ensuring fire safety. They are common fire protection equipment.

[0003] In order to sense and process the external environment, smoke and heat sensing devices require internal electronic equipment to transmit and receive signals for control. To ensure the stability of these devices, the influence of external substances on them should be minimized. Referring to Chinese patent CN201910482442.7, a mining smoke sensor is proposed. This patent uses a combination of internal and external covers to filter smoke, preventing external dust from entering the sensor and overcoming the shortcomings of existing smoke sensors that suffer from false alarms and missed alarms due to dust influence. This ensures the monitoring sensitivity of the mining smoke sensor. However, in actual use, in addition to the influence of dust, workplaces, whether shopping malls or offices, have a large number of people. When people use mobile phones and other electronic devices, as well as other facilities and equipment in the vicinity, they release electromagnetic signals. Abundant electromagnetic signals can cause static electricity in the smoke and heat sensing devices. These currents and static signals can interfere with the sensing equipment, causing the smoke and heat detection device to malfunction and resulting in unnecessary trouble. Utility Model Content

Both the mounting frame 1 and the metal shielding mesh 2 are made of metal. In addition to protecting the smoke and temperature alarm inside, the metal material of the metal shielding mesh 2 also provides electrostatic shielding to prevent external current from entering the smoke and temperature alarm. Furthermore, when external current comes into contact with the smoke and temperature sensor, the grounding wire 3 can effectively conduct the current to the ground, allowing the current to leave the device.
