Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electrical fire detection and alarm sensors, specifically an electrical fire detection and alarm sensor. Background Technology
[0002] Electrical fire detection and alarm sensors are intelligent safety devices used to monitor electrical equipment and the surrounding environment, detect fire hazards in advance, and issue alarms. Through real-time monitoring and analysis of various fire-related parameters, they can provide early warning of electrical fires, playing an important role in preventing fire accidents and reducing loss of life and property. The type should be selected according to the usage scenario: smoke + temperature composite sensor is preferred for homes; residual current monitoring type is selected for places with dense electrical equipment.
[0003] Existing electrical fire detection and alarm sensors use lithium battery structures, which are prone to dust ingress during heat dissipation. Therefore, they are not suitable for long-term exposure to high dust, oil fume, or humid environments (such as factory workshops and restaurant kitchens). This can easily cause contamination of the sensor's internal optical path or ion chamber, leading to a decrease in detection accuracy and requiring frequent cleaning and maintenance. Utility Model Content
[0004] The purpose of this invention is to provide an electrical fire detection and alarm sensor to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An electrical fire detection alarm sensor includes a sensor protective housing, a display screen, a mounting shell, and a mounting assembly. The display screen is mounted on a mounting point on the sensor protective housing, and the mounting shell is also mounted on a mounting point on the mounting assembly. The mounting assembly also includes a...
[0007] A heat dissipation and filtering assembly is mounted on the mounting housing;
[0008] A gap-sealing component is disposed on the display screen;
[0009] The mounting shell has a threaded snap-fit mounting plate, the display screen has an operation panel, the operation panel has a folding cover, and the mounting shell has a through-hole mounting bolt.
[0010] The electrical fire detection and alarm sensor described above: the folding cover is slidably mounted on the operation panel and the sensor protective housing.
[0011] As described above, the electrical fire detection and alarm sensor consists of a mounting housing and a mounting plate that are snapped together by mounting bolts.
[0012] The electrical fire detection and alarm sensor described above includes a heat dissipation and filtering assembly with mounting holes on a mounting plate, a flat membrane mounted in the center of the mounting plate, and heat dissipation holes on both sides of the mounting plate.
[0013] As described above, the electrical fire detection and alarm sensor includes a heat dissipation and filtering assembly that is fixedly connected to the folding cover, and the connection point of the flexible connecting cover is provided with a fitting cover.
[0014] The electrical fire detection alarm sensor described above: the gap blocking component includes a groove formed at the display mounting location, and a HEPA filter is provided at the mounting location on the groove.
[0015] The electrical fire detection alarm sensor described above: the HEPA filter and the groove are mounted on the display screen.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: the heat generated by the mounting shell and sensor protective shell is dissipated through the flat membrane, and ventilation is achieved through the heat dissipation holes on the mounting plate. This is beneficial for the electrical fire detection alarm sensor, which uses a lithium battery structure. During heat dissipation, dust can enter the heat dissipation holes and the interior of the flat membrane for filtration. The flexible connection cover is slidably installed on the operation panel, sensor protective shell, and display screen through a folding cover. The flexible connection cover and the folding cover are folded and unfolded on the operation panel and sensor protective shell for dust and fire protection, preventing dust from entering the mounting area of the mounting shell and sensor protective shell. The heat dissipation holes and the flat membrane are easily exposed to high dust, oil fume, or humid environments (such as factory workshops and restaurant kitchens) for a long time. The flat membrane can filter dust and block and isolate it.
[0017] HEPA filters use ultra-fine fibers (0.3~10μm in diameter) to filter particles ≥0.3μm through mechanisms such as Brownian motion, interception, and inertial collision. They separate particles and harmful substances in smoke through physical processes such as interception and adsorption. They can also seal the gaps at the installation points on the display screen and sensor protective housing to prevent contamination of the internal optical path or ion chamber of the sensor, prevent a decrease in detection accuracy, and reduce the frequency of cleaning and maintenance.
