Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aspirating smoke fire detectors, in particular to a novel aspirating smoke fire detector with waterproof, dustproof and sealing functions. Background Art
[0002] Traditional aspirating smoke detectors have significant limitations in terms of water and dust resistance, especially in high-humidity or dusty environments. They are easily affected by external factors, reducing detection accuracy and stability. To improve water and dust resistance, some traditional devices have added complex sealing structures. This design not only increases production costs but also results in larger detectors, limiting their application scenarios. Furthermore, over long-term operation, aging seals can lead to air leaks, ultimately affecting fire detection accuracy and the lifespan of the device. Improvements are needed. Utility Model Content
[0003] The purpose of this utility model is to solve the technical problems raised in the above background technology.
[0004] The utility model adopts the following technical solution: a novel aspirating smoke fire detector with waterproof, dustproof and sealing functions, comprising an upper cover and a lower cover, wherein the interior of the upper cover is rotatably connected with a bolt, one end of the bolt is fixedly installed with a fixing head, and a sealing block is provided on the surface of the bolt.
[0005] Preferably, a threaded groove is provided inside the lower cover, thereby simplifying the installation process of the upper cover and the lower cover and improving the structural stability of the device.
[0006] Preferably, the upper surface of the lower cover is provided with a connection port. This facilitates connection between the detector and external devices, enabling stable signal transmission. This structural design not only improves the scalability of the device but also ensures the reliability of data acquisition and transmission.
[0007] Preferably, the bottom end of the lower cover is provided with an air inlet, which allows smoke to enter the detection area in a timely manner, thereby improving the response speed and detection accuracy of the detector, thereby more effectively achieving fire early warning.
[0008] Preferably, the bolts are engaged with the thread grooves. Here, the engagement structure between the bolts and the thread grooves ensures a tight fit between the upper cover and the lower cover, further improving the sealing performance of the device.
[0009] Preferably, the sealing block is provided at the connection between the upper cover and the bolts, thereby providing an additional layer of protection for the entire device, enhancing the airtightness, effectively preventing the ingress of dust and moisture from the outside, and ensuring that the detector can still work stably in harsh environments.
[0010] Compared with the prior art, the advantages and positive effects of the present invention are:
[0011] This utility model utilizes an improved structural design with bolts to enhance waterproof and dustproof sealing, achieving reliable airtightness and adaptability for use in high-humidity or dusty environments. Unlike traditional aspirating smoke detectors, this method eliminates the need for complex waterproof and dustproof physical structures, reducing component size and manufacturing costs, making installation and maintenance more convenient. Furthermore, the tight fit between the bolts and the sealing block effectively ensures the detector's internal seal, preventing the ingress of external moisture and dust, thereby extending the device's service life and reliability.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0018] Example
[0019] See also Figure 1-2The present invention provides a technical solution: a novel aspirating smoke detector with waterproof and dustproof sealing functions, comprising an upper cover 1 and a lower cover 2. A bolt 6 is rotatably connected to the upper cover 1, with a fixed head 7 fixedly mounted on one end of the bolt 6, and a sealing block 8 provided on the surface of the bolt 6. The upper cover 1 is rotatably connected to the bolt 6, with a fixed head 7 fixedly mounted on one end of the bolt 6, and a sealing block 8 provided on the surface of the bolt 6. This design ensures an effective seal between the upper cover 1 and the lower cover 2, preventing the ingress of external moisture and dust, thereby enhancing the device's protective performance and making it suitable for use in harsh environments. The lower cover 2 has a threaded groove 3 formed inside, which securely engages the bolt 6 with the lower cover 2. This design simplifies the installation process of the upper and lower covers 1 and 2, improves the structural stability of the device, and prevents seal failure caused by vibration or impact, thereby extending the device's service life. A connector 4 is provided on the upper surface of the lower cover 2. The connector 4 facilitates connection between the detector and external equipment, ensuring stable signal transmission. This structural design not only improves the scalability of the device, but also ensures the reliability of data collection and transmission, and is adaptable to more application scenarios. An air inlet 5 is provided at the bottom end of the lower cover 2. The air inlet 5 at the bottom end of the lower cover 2 is designed to optimize the channel for gas to enter the device, allowing smoke to enter the detection area in a timely manner, improving the response speed and detection accuracy of the detector, and thus more effectively achieving fire warning. The bolt 6 is engaged with the thread groove 3. The engagement structure between the bolt 6 and the thread groove 3 ensures a tight fit between the upper cover 1 and the lower cover 2, further improving the sealing performance of the device. This design effectively prevents the internal structure of the device from being exposed to air moisture, thereby improving the reliability and durability of the device. The sealing block 8 is provided at the connection between the upper cover 1 and the bolt 6. The sealing block 8 is provided at the connection between the upper cover 1 and the bolt 6, providing an additional layer of protection for the entire device, enhancing the airtightness, effectively preventing the entry of external dust and moisture, and ensuring that the detector can still work stably in harsh environments.
[0020] Working Principle: The upper cover 1 and lower cover 2 form a tight seal within the internal structure. Bolts 6 in the upper cover 1 are fixed with a fixed head 7 at one end, which engages with the lower cover 2 via a threaded groove 3, thereby achieving a secure connection between the upper and lower covers 1 and 2. A sealing block 8 is provided at the joint to prevent outside air, moisture, or dust from entering the device. An air inlet 5 is provided at the bottom end of the lower cover 2 to facilitate the entry of external air into the detection area, while a connection port 4 is used to connect to an external system for smoke sampling and data transmission.
