Description

Technical Field

[0001] The utility model relates to the technical field of fire safety equipment, in particular to a smoke and temperature sensing threshold control device. Background Art

[0002] With technological advancements and growing public awareness of safety, fire warning systems are becoming increasingly popular in homes, businesses, and even industrial environments. Smoke and temperature threshold control devices are integrated smoke detectors and temperature sensors, typically installed in strategic locations within buildings. They monitor changes in the concentration of suspended particles in the air (i.e., smoke) and abnormal increases in ambient temperature to identify potential fire risks and issue timely alarm signals, allowing people to quickly take appropriate preventative measures.

[0003] However, in actual applications, it was found that due to the lack of sufficient protective measures, the existing equipment, in the humid or rainy season in the south, the high moisture content in the air causes condensation on the outer casing, which can easily flow into the interior of the equipment and cause corrosion of internal electronic components. Utility Model Content

[0004] In order to solve the problems in the above background technology, the present invention provides a smoke and temperature sensor threshold control device.

[0005] The solution adopted by the present invention to solve its technical problems is: a smoke and temperature sensing threshold control device, including a shell, a cavity provided in the shell, and a detection component provided in the cavity for monitoring the smoke concentration and temperature changes in the environment, the shell including a bottom shell and a top cover, a plurality of rows of first air inlet holes connected to the cavity are arranged around the circumference in the middle position of the side wall of the top cover, the bottom shell extends from the edge to form an extended side covering the first air inlet holes, and a plurality of rows of second air inlet holes are provided on the extended side, and any row of the first air inlet holes and any row of the second air inlet holes are staggered with each other.

[0006] By adopting this technical solution, the staggered arrangement of the first and second air inlets creates a non-linear channel, allowing suspended particles (such as smoke) and temperature changes in the air to enter the device and be captured by the detection component. Furthermore, the first and second air inlets are spaced apart and staggered, ensuring that even if water droplets condense on the outer surface of the top cover, they will not drip directly into the device, effectively protecting the sensitive electronic components within from moisture damage.

[0007] Furthermore, a baffle is provided around the circumference of the bottom shell for preventing water accumulated in the bottom shell from flowing into the first air inlet hole, and a guide groove is formed between the baffle and the bottom shell.

[0008] By adopting the above technical solutions, the waterproof performance of the equipment is further improved, ensuring that the equipment can operate normally in a humid or rainy environment.

[0009] Furthermore, the detection component includes a control panel installed in the cavity, and a smoke sensor and a temperature sensor installed on the side of the control panel facing the smoke inlet.

[0010] By adopting the above technical solutions, smoke detection and temperature detection can be provided.

[0011] Furthermore, an annular moisture absorbing plate is provided in the shell, and the annular moisture absorbing plate is arranged on the peripheral side of the control plate.

[0012] By adopting the above technical solution, moisture inside the shell can be effectively absorbed, thereby protecting the control board from moisture erosion and ensuring the stable operation of the electronic equipment.

[0013] Furthermore, the shell is coated with a hydrophobic nano coating for causing the formed water droplets to slide off quickly.

[0014] By adopting the above technical solution, the chance of water droplets forming can be reduced, and the formed water droplets can be prompted to slide down quickly instead of accumulating.

[0015] To sum up, the beneficial effects of the present invention are as follows: the present invention effectively prevents moisture on the shell from directly dripping into the interior of the device through the staggered first air inlet hole and the second air inlet hole, thereby protecting the internal sensitive electronic components from moisture damage, while ensuring that suspended particles and temperature change information in the air can smoothly enter the interior of the device.

[0016] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification. In addition, in order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following preferred embodiments are specifically cited and described in detail with reference to the accompanying drawings.

[0021] In order to make the content of the present invention more clearly understood, the present invention will be further described below based on specific embodiments in conjunction with the accompanying drawings.

[0022] It should be noted that the terms "center," "upper," "lower," "front," "back," "left," "right," "inner," and "outer" used herein to indicate positions or locations are based on the positions or locations shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Unless otherwise specified, "plurality" means two or more.

[0023] Unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0024] like Figures 1 to 3 As shown, a smoke and temperature sensing threshold control device is provided, wherein this embodiment includes a shell 1, a cavity 13 provided in the shell 1, and a detection component 3 provided in the cavity 13 for monitoring the smoke concentration and temperature changes in the environment. The shell 1 includes a bottom shell 11 and a top cover 12, and multiple rows of first air inlet holes 121 connected to the cavity 13 are arranged around the circumference in the middle position of the side wall of the top cover 12. An extended side 14 covering the first air inlet holes 121 is formed on the bottom shell 11 extending from the edge, and multiple rows of second air inlet holes 141 are provided on the extended side 14. Any row of first air inlet holes 121 and any row of second air inlet holes 141 are staggered with each other.

[0025] The device housing 1 of this embodiment consists of a bottom shell 11 and a top cover 12. A detection component 3 is installed in the housing 1 for real-time monitoring of smoke concentration and temperature changes in the environment. Multiple rows of first air inlets 121 communicating with the internal cavity 13 are evenly distributed on the side walls of the top cover 12. These air inlets are all located in the central area of ​​the top cover 12. The bottom shell 11 extends an extended edge 14 from a side edge close to the top cover 12. The extended edge 14 covers and protects the first air inlet 121. At the same time, multiple rows of second air inlets 141 opening from the bottom are specially designed on the extended edge 14. These second air inlets 141 are staggered with the first air inlet 121 on the top cover 12. Through the non-linear channel formed by the staggered first and second air inlets 141, suspended particles (such as smoke) and temperature change information in the air are able to enter the interior of the device and be captured by the detection component 3. A certain spacing is maintained between the first and second air inlet holes 121, 141, and their staggered arrangement ensures that even if water droplets condense on the outer surface of the top cover 12, they will not drip directly into the device. Instead, the water droplets will flow out along the surface of the housing 1, or flow into the first air inlet hole 121. Because the second air inlet hole 141 is staggered with it, the water droplets slide into the groove formed between the extended edge 14 and the top cover 12. Moreover, because the first air inlet hole 121 extends to the bottom and the second air inlet hole 141 is located only in the middle, the water droplets can be discharged through the first air inlet hole 121 at the bottom of the device after installation, effectively protecting the sensitive electronic components inside from damage by moisture.

[0026] like Figure 2 As shown, the bottom shell 11 of this embodiment is circumferentially provided with a baffle 2 to prevent water accumulated on the bottom shell 11 from flowing into the first air inlet 121. A guide groove 21 is formed between the baffle 2 and the bottom shell 11. A baffle 2 is provided along the circumference of the outer edge of the bottom shell 11. Its primary function is to prevent water accumulated on the bottom shell 11 from flowing directly into the first air inlet 121 of the device. A guide groove 21 is formed between this baffle 2 and the bottom shell 11. Its design is to guide and disperse moisture accumulated on the surface of the bottom shell 11. When water droplets or rainwater accumulates on the bottom shell 11, the baffle 2 effectively blocks this moisture, preventing it from flowing directly into the first air inlet 121. Furthermore, the guide groove 21 between the baffle 2 and the bottom shell 11 directs the accumulated moisture to the edge of the bottom shell 11 or other specially designed drain outlets, thereby ensuring that moisture does not enter the interior of the device and avoiding the risk of damage or malfunction caused by accumulated water.

[0027] like Figure 2 as well as Figure 3As shown, the detection component 3 of this embodiment includes a control panel 31 installed in the cavity 13, and a smoke probe 32 and a temperature probe 33 installed on the side of the control panel 31 facing the smoke inlet. The smoke probe 32 is installed on the side of the control panel 31 facing the smoke inlet, and is used to monitor the concentration of suspended particles (i.e., smoke) in the air, while the temperature probe 33 is set next to the smoke probe 32 to sense changes in the ambient temperature. Alarm devices such as buzzers are set on the back of the control panel 31. The control panel 31 serves as a core processing unit and can process data from the smoke probe 32 and the temperature probe 33 in real time, and analyze and judge according to preset thresholds. When the detected smoke concentration or temperature exceeds the set threshold, the control panel 31 will immediately trigger the alarm system, and send out a warning signal through devices such as buzzers to remind people to take corresponding safety measures.

[0028] like Figure 2 as well as Figure 3 As shown, the housing 1 of this embodiment further includes an annular moisture-absorbing plate 4, which is arranged around the control board 31. The annular moisture-absorbing plate is embedded within the housing 1 and surrounds the control board 31. Its material properties actively absorb surrounding moisture. Even if a small amount of moisture enters the housing 1 through other protective measures, it is quickly absorbed by the moisture-absorbing plate, preventing it from contacting sensitive electronic components.

[0029] Furthermore, the housing 1 of this embodiment is coated with a hydrophobic nanocoating designed to encourage water droplets to slide off quickly. This coating possesses unique chemical and physical properties, effectively enabling water droplets to slide off the surface of the housing 1. Specifically, the low surface tension of this hydrophobic nanocoating prevents water droplets from easily adhering to the coating surface, causing them to slide off quickly. This coating is typically composed of nanoscale hydrophobic particles uniformly distributed throughout the coating, forming a dense and uniform protective layer.

[0030] In summary, the beneficial effects of this embodiment are as follows: The staggered arrangement of first and second air inlet holes 121, 141 ensures that suspended particles and temperature change information in the air can smoothly enter the device, while effectively preventing moisture from directly dripping into the device, protecting sensitive internal electronic components from moisture damage. Furthermore, the annular moisture-absorbing plate 4 provided within the housing 1 further enhances the device's moisture protection capabilities, while the baffle 2 and guide groove 21 further prevent water from entering the housing 1. The application of a hydrophobic nanocoating ensures that water droplets on the surface of the housing 1 slide off quickly, further enhancing the device's protective performance.

[0031] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
