Description

Technical Field

[0001] This utility model relates to the field of smoke detectors, and in particular to a smoke detector with good weather resistance. Background Technology

[0002] Smoke detectors are devices that can detect smoke in the environment and issue timely alarms. They are widely used in various scenarios such as homes, shopping malls, factories, and outdoor places. In modern fire safety systems, smoke detectors are core devices for early fire warning. Their working environments are often complex and varied, whether it is a high-temperature and high-humidity industrial workshop, a chemical plant with many corrosive gases, or an outdoor area that is exposed to direct sunlight for a long time.

[0003] Traditional smoke detectors have insufficient weather resistance. Their outer casing is easily aged and cracked by ultraviolet radiation, corroded and damaged in acidic and alkaline environments, and their material properties degrade at high temperatures, leading to structural deformation. This can cause internal sensing elements to fail, resulting in false alarms, missed alarms, or even complete paralysis, making it difficult to meet the long-term and stable fire early warning requirements.

[0004] Therefore, it is necessary to provide a smoke sensor with good weather resistance to solve the above-mentioned technical problems. The information disclosed in this background section is only intended to enhance the understanding of the overall background of this utility model, and is not necessarily to be regarded as an admission or to imply in any way that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] This utility model provides a smoke sensor with good weather resistance, which solves the technical problems of insufficient weather resistance of fog sensors, easy aging and cracking of the outer shell due to ultraviolet radiation, corrosion and damage in acid and alkaline environments, and structural deformation caused by material performance degradation at high temperatures, which in turn causes the internal sensing element to fail, resulting in false alarms, missed alarms or even complete paralysis, making it difficult to meet the technical requirements of long-term stable fire early warning.

[0006] To solve the above technical problems, this utility model provides a smoke sensor with good weather resistance, including a mounting base. A smoke sensor body is mounted on the upper end of the mounting base. The smoke sensor body includes a plastic shell base layer, an anti-corrosion layer, a heat-resistant layer, and an ultraviolet-resistant layer. The plastic shell base layer is disposed on the inner surface of the anti-corrosion layer, the anti-corrosion layer is disposed on the inner surface of the heat-resistant layer, and the heat-resistant layer is disposed on the inner surface of the ultraviolet-resistant layer.

[0007] The anti-corrosion layer includes a polytetrafluoroethylene coating and a polyimide layer, wherein the polyimide layer is disposed on the outer surface of the polytetrafluoroethylene coating;

[0008] The UV-resistant layer comprises a polypropylene material layer and an acrylate coating, wherein the acrylate coating is disposed on the outer surface of the polypropylene material layer.

[0009] Preferably, a fixing block is installed at the lower end of the outer surface of the mounting base, and a mounting hole is opened on the upper end face of the fixing block, with the lower end of the mounting hole extending to the lower end face of the fixing block.

[0010] Preferably, a smoke detection head is provided at the upper end of the smoke sensor body, a detection hole is provided in a ring on the outer surface of the smoke detection head, a switch button is provided on the front side of the upper end of the smoke detection head, and the material of the smoke detection head is the same as that of the smoke sensor body.

[0013] Preferably, the smoke sensor body is internally equipped with a main control module, a smoke sensing module, and a power supply module.

[0014] Compared with related technologies, the smoke sensor with good weather resistance provided by this utility model has the following beneficial effects:

[0015] This utility model provides a smoke sensor with good weather resistance. The plastic shell base provides good structural support, the anti-corrosion layer has excellent corrosion resistance and can resist the erosion of various chemicals, the temperature resistant layer can maintain stable performance in high temperature environment, and the ultraviolet resistant layer can effectively block ultraviolet rays and prevent the plastic shell base from aging. The synergistic effect of each layer significantly improves the weather resistance of the plastic shell base. The smoke sensor body and the mounting base are fixed to the target position as a whole by fixing blocks and mounting holes.

[0016] This utility model provides a smoke sensor with good weather resistance. Smoke enters the internal detection chamber through the annular detection hole on the outer surface of the smoke detection head. The smoke sensing module monitors the changes in smoke concentration in real time and converts the light signal or ion signal into an electrical signal, which is then transmitted to the main control module.

[0027] The UV-resistant layer 6 includes a polypropylene material layer 601 and an acrylic coating 602, with the acrylic coating 602 disposed on the outer surface of the polypropylene material layer 601.

[0028] In this embodiment, the outer shell of the smoke sensor body 2 adopts a composite structure of "plastic shell base layer 3, anti-corrosion layer 4, heat-resistant layer 5, and UV-resistant layer 6". The layers work together to form a three-dimensional protection system. The plastic shell base layer 3 provides solid support for the overall structure and has good mechanical strength and formability. The anti-corrosion layer 4, with its polytetrafluoroethylene coating 401 and polyimide layer 402 from the inside out, can resist the penetration of various chemical corrosive media, further enhancing chemical resistance and structural stability. The dual protection significantly improves the equipment's corrosion resistance in harsh environments such as acid, alkali, and salt spray. The heat-resistant layer 5 effectively blocks the conduction of external high temperatures, enabling the equipment to work stably in a wide temperature range of -40℃ to 120℃. The polypropylene material layer 601 and the acrylic coating 602 of the UV-resistant layer 6 form a UV barrier, which together delays material aging and extends the outdoor service life.

The overall material weather resistance is consistent with the main body, preventing the installation part from loosening due to rust and aging. The installation interfaces of functional components such as the detection indicator light and alarm speaker are sealed to form a unified protection system with the shell, ensuring the sound and light alarm performance in harsh environments.
