Description

Technical Field

[0001] This invention belongs to the field of smoke detector technology, and in particular relates to an inhalation-type anti-clogging smoke detection device. Background Technology

[0002] Smoke detectors, also known as smoke-sensing fire detectors, smoke detectors, smoke probes, and smoke sensors, are primarily used in fire protection systems and also have applications in security systems. They are a typical example of equipment adapted from space-based fire protection measures for civilian use. Smoke detectors primarily prevent fires by monitoring the concentration of smoke. Internally, they employ ionization smoke sensing, a technologically advanced and reliable sensor widely used in various fire alarm systems, offering performance far superior to gas-sensitive resistor-based fire alarms. Inhalation smoke detectors are a common type of smoke detector on the market. While existing models generally meet users' routine needs, some significant technical flaws and shortcomings have emerged in practical applications. Specifically, these detectors rely on built-in fans and other power equipment to create a negative pressure environment, actively drawing in outside air to analyze smoke concentration. However, due to the complexity and diversity of operating environments—for example, the presence of high concentrations of dust, fibers, or other suspended particles in the air—these impurities are easily drawn into the air intake. Over time, these impurities accumulate, eventually causing blockage of the air intake channel. Once blocked, outside air cannot smoothly enter the detector, causing the negative pressure system to overheat due to continuous idling, potentially burning out the fan or other critical components. Furthermore, blockage significantly reduces the detector's sensitivity and response speed, affecting its normal smoke monitoring function and even causing missed or false alarms, posing a potential threat to overall fire safety.

[0003] To address these issues, we provide an inhalation-type anti-clogging smoke detection device. Summary of the Invention

[0004] The purpose of this invention is to provide an inhalation-type anti-clogging smoke detection device, which can solve the problem that existing inhalation detectors rely on internal fans and other equipment to generate negative pressure to draw in external air for detection. However, due to the different detection environments, when dust and other impurities enter the air inlet of the detection device and cause blockage, external air can no longer enter, which can easily lead to the burning of the internal negative pressure structure and affect subsequent detection.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to an inhalation-type anti-clogging smoke detection device, comprising a detector body and a mounting base. The detector body has a mounting base at its upper end, a fixing structure at its upper end, and a disassembly structure inside the mounting base.

[0011] Preferably, mounting holes are provided on both sides of the surface of the mounting base, and a connecting column is fixedly installed in the middle of the lower end of the mounting base. The diameter of the connecting column is the same as the diameter of the connecting hole. The connecting column passes through the connecting hole and is movably inserted into the interior of the connecting sleeve. Mounting grooves are provided on both sides of the surface of the connecting column. A locking spring is fixedly installed inside the mounting groove. A locking block is fixedly installed at one end of the locking spring. One end of the locking block is movably inserted into the outside of the connecting column and fits against the upper end of the inner wall of the connecting sleeve. One side of the lower end of the locking block is inclined.

[0012] Preferably, a reset sleeve is movably installed inside the connecting sleeve. The inner diameter of the reset sleeve is equal to the diameter of the connecting column. A support spring is installed at the lower end of the reset sleeve. Movable grooves are provided on both sides of the surface of the connecting sleeve.

[0013] Preferably, support tubes are fixedly installed on both sides inside the mounting base, and a fixed suction cup is fixedly installed at the upper end of the support tube. The fixed suction cup is located on the outside of the mounting base. An air inlet hole connected to the support tube is opened in the middle of the fixed suction cup.

Adjustment blocks are movably inserted inside the adjustment grooves. Adjustment rings connected to the adjustment blocks are movably sleeved on the outside of the mounting base.

[0015] The present invention has the following beneficial effects: 1. In this invention, under the action of the filter screen inside the air guide hood, the flue gas entering the air guide hood will first pass through the filter screen for preliminary filtration. The filter screen can effectively intercept larger particles and impurities in the flue gas, preventing them from entering the air guide hood and causing blockage, thus affecting the normal operation of the device. At the same time, when the drive motor starts, it will drive the transmission gear to rotate. Since the transmission gear meshes with the rotating gear ring, it will drive the rotating gear ring to rotate, causing the filter screen to rotate inside the air guide hood. During the rotation, the rubber scraper that is in contact with the outer side of the filter screen will continuously scrape off the particles and impurities attached to the surface of the filter screen, further ensuring the filtration effect of the filter screen and ensuring that it will not be blocked due to long-term use, always maintaining good ventilation and filtration performance, providing a strong guarantee for the stable and reliable operation of the entire inhalation-type anti-clogging smoke detection device. Under the action of the limiting column, the filter screen can be tightly fitted with the inner wall of the air guide hood, enhancing the filtration effect. 2. In this invention, when it is necessary to connect the air guide cover to the detector body, the operator only needs to align the upper end of the mounting screw sleeve of the air guide cover with the lower end of the outer threaded seat, and then rotate the mounting screw sleeve. Since the outer threaded seat is fixed at the lower end of the detector body, as the mounting screw sleeve rotates, it will move upward along the outer threaded seat, thereby gradually connecting the air guide cover and the detector body tightly together. The design of the anti-slip protrusion increases the friction when the operator rotates the mounting screw sleeve, making the connection process easier and more convenient. Even when the hands are sweaty or oily, the connection operation between the air guide cover and the detector body can be completed smoothly. Moreover, this connection structure is stable and reliable and can withstand a certain amount of external impact, ensuring that the air guide cover will not easily fall off during the use of the detector, thus ensuring the structural integrity and normal operation of the entire inhalation-type anti-clogging smoke detection device. 3. In this invention, when installing the air guide cover, the user pulls the clamping rod, which moves the limiting tooth block to compress the clamping spring. This causes the limiting tooth block to retract into the mounting groove. After the air guide cover is initially connected to the outer threaded seat through the mounting screw sleeve, the groove moves to one side of the annular groove. The user releases the pull block, and the limiting tooth block, under the action of the clamping spring, inserts into the annular groove and engages with the limiting tooth ring, preventing the air guide cover from rotating. This avoids the filter screen rotating when it rotates, which would affect the use of the air guide cover and the cleaning of the filter screen. At the same time, it further strengthens the fixed installation of the air guide cover. This design is not only simple and convenient to operate, but also effectively prevents the air guide cover from loosening due to vibration or external force during use, ensuring that the entire inhalation-type anti-clogging smoke detection device always maintains a good working condition, further improving the reliability and stability of the device. 4. In this invention, the design of the fixing suction cup plays a crucial connecting role between the detector body and the mounting base, greatly enhancing the overall stability of the detector body. When the detector body needs temporary use, the operator can use the fixing suction cup to quickly and firmly attach it to the designated surface without complex drilling or installation procedures, thus achieving rapid turnover and flexible deployment. This design is particularly suitable for smooth and flat surfaces, such as glass, tile, or metal surfaces. The fixing suction cup fully utilizes the principle of negative pressure adsorption to achieve excellent fixing effect. In addition, this fixing method can effectively resist external collisions or vibration interference, preventing the mounting base from loosening due to accidental force, further ensuring that the detector body is always firmly in the preset position. In this way, the detector can not only continuously and reliably perform smoke detection tasks, but also greatly improve its adaptability and practicality in changing environments.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 10 As shown, this embodiment provides an inhalation-type anti-clogging smoke detection device, including a detector body 100 and a mounting base 300. The upper end of the detector body 100 is provided with a mounting base 110, and the mounting base 110 is provided with a disassembly structure. The lower end of the detector body 100 is detachably mounted with an air guide hood 200. Air inlets 201 are provided on both sides of the surface of the air guide hood 200. An air guide sleeve 130 is provided in the middle of the lower end of the detector body 100. A fixing frame is installed at the upper end of the air guide sleeve 130. An air guide motor 133 is provided at the upper end of the fixing frame. An air suction impeller 134 is installed at the output end of the air guide motor 133. An mounting bracket 131 is installed at the lower end of the air guide sleeve 130. An ionization smoke sensor 132 is installed at the lower end of the mounting bracket 131. Ventilation holes 101 are provided on both sides of the surface of the detector body 100. In this embodiment, the main body of the detector is securely installed at a designated location in the application area using a pre-designed fixing structure. Subsequently, the air guide motor 133 starts and runs, driving the suction impeller 134 to rotate at a stable speed through its internal motor transmission system. This rotational motion creates a continuous and uniform negative pressure suction inside the air guide sleeve 130, effectively guiding external smoke through the air inlet 201 on the air guide hood 200 and drawing it into the internal space of the air guide sleeve 130. After the smoke enters the air guide sleeve 130, the ionization smoke sensor 132 located inside it begins to work, using its highly sensitive detection mechanism to perform real-time analysis and monitoring of particulate matter and chemical components in the smoke. Throughout the process, the coordinated operation of each component ensures high accuracy and reliability of smoke detection, thereby enabling the entire device to exhibit excellent detection effects and stable performance in practical applications.

[0022] like Figures 4 to 7 As shown in the figure, this embodiment provides an inhalation-type anti-clogging smoke detection device. The air guide hood 200 is provided with an anti-clogging structure inside. The anti-clogging structure includes a filter screen 210, which is rotatably installed inside the air guide hood 200. The filter screen 210 is annular. Limiting posts 203 are provided on both sides inside the air guide hood 200. The limiting posts 203 are located on one side of the inner ring of the filter screen 210. The limiting posts 203 and the air inlet 201 are staggered. A rotating gear ring 211 is installed at the upper end of the air guide hood 200. A drive motor 140 is installed inside the detector body 100. The output end of the drive motor 140 extends to the outside of the detector body 100 and is equipped with a transmission gear 141. The transmission gear 141 meshes with the rotating gear ring 211. A rubber scraper 202 is provided on one side of the inner wall of the air inlet 201. One end of the rubber scraper 202 is attached to the outside of the filter screen 210. In this embodiment, under the action of the filter screen 210 inside the air guide hood 200, the flue gas entering the air guide hood 200 will first pass through the filter screen 210 for preliminary filtration. The filter screen 210 can effectively intercept larger particles and impurities in the flue gas, preventing them from entering the air guide sleeve 130 and causing blockage, thus affecting the normal operation of the device. At the same time, when the drive motor 140 starts, it will drive the transmission gear 141 to rotate. Since the transmission gear 141 meshes with the rotating gear ring 211, it will drive the rotating gear ring 211 to rotate, causing the filter screen 210 to rotate inside the air guide hood 200. During rotation, the rubber scraper 202, which is in contact with the outer side of the filter screen 210, continuously scrapes away particles and impurities attached to the surface of the filter screen 210, further ensuring the filtration effect of the filter screen 210 and ensuring that it will not be blocked due to long-term use. It maintains good ventilation and filtration performance at all times, providing a strong guarantee for the stable and reliable operation of the entire inhalation-type anti-clogging smoke detection device. Under the action of the limiting column 203, the filter screen 210 can be tightly fitted with the inner wall of the air guide hood 200, enhancing the filtration effect.

[0023] like Figure 4 and Figure 5 As shown in the figure, the inhalation-type anti-clogging smoke detection device provided in this embodiment has a connection structure between the air guide hood 200 and the detector body 100. The connection structure includes an outer threaded seat 102, the lower end of which is located at the lower end of the detector body 100. An installation screw sleeve 230 is rotatably installed on the outer side of the outer threaded seat 102. The lower end of the installation screw sleeve 230 is rotatably connected to the upper end of the air guide hood 200. Anti-slip protrusions are evenly provided on the outer side of the installation screw sleeve 230. In this embodiment, when it is necessary to connect the air guide shroud 200 to the detector body 100, the operator only needs to align the mounting sleeve 230 at the upper end of the air guide shroud 200 with the lower end of the outer threaded seat 102, and then rotate the mounting sleeve 230. Since the outer threaded seat 102 is fixed to the lower end of the detector body 100, as the mounting sleeve 230 rotates, it will move upward along the outer threaded seat 102, thereby gradually connecting the air guide shroud 200 and the detector body 100 tightly together. The design of the anti-slip protrusion increases the friction when the operator rotates the mounting sleeve 230, making the connection process easier and more convenient. Even when the hands are sweaty or oily, the connection operation between the air guide shroud 200 and the detector body 100 can be completed smoothly. Moreover, this connection structure is stable and reliable and can withstand a certain amount of external impact, ensuring that the air guide shroud 200 will not easily fall off during the use of the detector, thus ensuring the structural integrity and normal operation of the entire inhalation-type anti-clogging smoke detection device.

[0024] like Figure 4 and Figure 5As shown, this embodiment provides an inhalation-type anti-clogging smoke detection device. An annular groove 150 is provided on the outer side of the threaded seat 102. A limiting toothed ring 151 is provided on the inner ring of the annular groove 150. A groove is provided on one side of the upper end of the inner wall of the air guide hood 200. A pressing rod 222 is movably inserted into the inside of the groove. One end of the pressing rod 222 is movably inserted into the outer side of the air guide hood 200 and is equipped with a pull block. The other end of the pressing rod 222 is movably inserted into the inside of the annular groove 150 and is equipped with a limiting toothed block 220. The limiting toothed block 220 is engaged with the limiting toothed ring 151. A pressing spring 221 that cooperates with the inner wall of the groove and the limiting toothed block 220 is sleeved on the surface of the pressing rod 222. In this embodiment, when installing the air guide cover 200, the user pulls the clamping rod 222, which moves the limiting tooth block 220, compressing the clamping spring 221. This causes the limiting tooth block 220 to retract into the mounting groove. After the air guide cover 200 is initially connected to the outer threaded seat 102 via the mounting screw sleeve 230, the groove moves to one side of the annular groove 150. The user releases the pull block, and the limiting tooth block 220, under the action of the clamping spring 221, inserts into the annular groove 150, engaging with the limiting tooth ring 1. The 51-phase snap-fit ​​design prevents the air guide cover 200 from rotating, thus avoiding the filter screen cover 210 from rotating and affecting its use and cleaning. This design also further strengthens the secure installation of the air guide cover 200. This design is not only simple and convenient to operate, but also effectively prevents the air guide cover 200 from loosening due to vibration or external force during use, ensuring that the entire inhalation-type anti-clogging smoke detection device always maintains good working condition, further improving the reliability and stability of the device.

[0025] like Figure 4 , Figure 6 and Figure 10As shown, this embodiment provides an inhalation-type anti-clogging smoke detection device. The upper end of the mounting base 110 is provided with a fixing structure, including a connecting hole 114. The connecting hole 114 is located in the middle of the upper end of the mounting base 110. A connecting sleeve 160 is fixedly installed in the middle of the interior of the mounting base 110. The connecting sleeve 160 is connected to the connecting hole 114, and the inner diameter of the connecting sleeve 160 is larger than the inner diameter of the connecting hole 114. Mounting holes 301 are provided on both sides of the surface of the mounting base 300, and a mounting hole 301 is located in the middle of the lower end of the mounting base 300. A connecting post 310 is fixedly installed. The diameter of the connecting post 310 is the same as the diameter of the connecting hole 114. The connecting post 310 passes through the connecting hole 114 and is movably inserted into the interior of the connecting sleeve 160. Mounting grooves are provided on both sides of the surface of the connecting post 310. A locking spring 312 is fixedly installed inside the mounting groove. A locking block 311 is fixedly installed at one end of the locking spring 312. One end of the locking block 311 is movably inserted into the outside of the connecting post 310 and fits against the upper end of the inner wall of the connecting sleeve 160. One side of the lower end of the locking block 311 is inclined. In this embodiment, the user fixes the mounting base 300 to the place of use using the fixing bolts and mounting holes 301. Then, the user picks up the detector body 100, aligns the connecting post 310 with the connecting hole 114 on the mounting base 110, and slowly presses down the detector body 100, allowing the connecting post 310 to pass through the connecting hole 114 and enter the connecting sleeve 160. During the process of the connecting post 310 entering, the inner wall of the connecting sleeve 160 presses against the locking block 311. Since one side of the lower end of the locking block 311 is inclined, the locking block 311 will retract into the mounting groove, while compressing the locking spring 312. When the connecting post 310 is fully inserted into the connecting sleeve 160 and the locking block 311 moves to the corresponding position on the inner wall of the connecting sleeve 160, the locking block... 311 pops out under the action of the locking spring 312 and fits tightly against the upper end of the inner wall of the connecting sleeve 160, thereby firmly fixing the detector body 100 to the mounting base 300. This fixing structure is ingeniously designed, and the installation and disassembly process is very simple. It can be completed with just a simple pressing and pulling operation, which greatly saves the time and labor costs of installation and disassembly. Moreover, the cooperation between the locking spring 312 and the locking block 311 makes the fixing effect very reliable, which can effectively prevent the detector body 100 from loosening and falling off due to vibration or external force during use. This ensures that the inhalation-type anti-clogging smoke detector can operate stably and continuously perform its smoke detection function, providing reliable protection for the safety of the place of use.

[0026] like Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, support tubes 122 are fixedly installed on both sides inside the mounting base 110, and a fixed suction cup 120 is fixedly installed on the upper end of the support tube 122. The fixed suction cup 120 is located on the outside of the mounting base 110. In this embodiment, the design of the fixing suction cup 120 plays a crucial connecting role between the detector body 100 and the mounting base 300, greatly enhancing the overall stability of the detector body 100. When the detector body 100 needs to be used temporarily, the operator can use the fixing suction cup 120 to quickly and firmly attach it to the designated surface without the need for complex drilling or fixing installation procedures, thus achieving rapid turnover and flexible deployment. This design is particularly suitable for smooth and flat surfaces, such as glass, tile, or metal surfaces. The fixing suction cup 120 can fully utilize the negative pressure adsorption principle to achieve excellent fixing effect. In addition, this fixing method can effectively resist external collisions or vibration interference, prevent the mounting base 110 from loosening due to accidental force, and further ensure that the detector body 100 is always firmly in the preset position. In this way, the detector can not only continuously and reliably perform smoke detection tasks, but also greatly improve its adaptability and practicality in changing environments.

[0027] like Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, a reset sleeve 161 is movably installed inside the connecting sleeve 160. The inner diameter of the reset sleeve 161 is equal to the diameter of the connecting post 310. A support spring 162 is installed at the lower end of the reset sleeve 161. Moving grooves 163 are provided on both sides of the surface of the connecting sleeve 160. Moving blocks 164 connected to the reset sleeve 161 are movably inserted inside the moving grooves 163. An air inlet 121 connected to the support tube 122 is provided in the middle of the fixed suction cup 120. A sealing ring 125 is fixedly installed inside the support tube 122. An adjusting rod 127 is movably inserted inside the support tube 122. A connecting rod 127 is installed at the upper end of the adjusting rod 127. The sealing block 126 is matched with 125. The support tube 122 has grooves 123 on both sides. The slider 124 connected to the adjusting rod 127 is movably inserted inside the groove 123. The mounting base 110 has a movable plate 170 installed inside. The movable plate 170 is movably sleeved on the outside of the connecting sleeve 160 and the support tube 122. The movable plate 170 is fixedly connected to the slider 124 and the movable block 164. The mounting base 110 has adjusting grooves 112 on both sides. The adjusting block 113 is movably inserted inside the adjusting groove 112. The adjusting ring 111 connected to the adjusting block 113 is movably sleeved on the outside of the mounting base 110. In this embodiment, when the detector body 100 needs to be disassembled for maintenance or repositioned, the operator only needs to rotate the adjusting ring 111. The adjusting ring 111 drives the adjusting block 113 to move inside the adjusting groove 112. The adjusting block 113 then drives the moving plate 170 to move up and down along the outside of the connecting sleeve 160 and the support tube 122. During the movement of the moving plate 170, the adjusting rod 127 moves inside the support tube 122 via the slider 124. The sealing block 126 at the upper end of the adjusting rod 127 cooperates with the sealing ring 125 to control the opening and closing of the air inlet 121. When the moving plate 170 moves upward, the sealing block 126 leaves the sealing ring 125, the air inlet 121 opens, and outside air enters the fixed suction cup 120, disrupting the negative pressure environment inside and separating the fixed suction cup 120 from the surface of use, facilitating detection. The disassembly of the detector body 100 is accompanied by the upward movement of the moving plate 170, which in turn drives the reset sleeve 161 to move upward inside the connecting sleeve 160 via the moving block 164. This stretches the support spring 162, causing the reset sleeve 161 to fit onto the surface of the connecting post 310. This causes the locking block 311 to retract inside the connecting post 310, allowing the connecting post 310 to be pulled out from inside the connecting hole 114. Once the connecting post 310 is completely pulled out from inside the connecting sleeve 160, the elastic force of the support spring 162 will cause the reset sleeve 161 to return to its initial position, preparing it for the next installation. This design makes the disassembly process of the detector body 100 simple and quick, and ensures that each component returns to its initial state after disassembly, facilitating subsequent reinstallation and use. This further enhances the practicality and convenience of the inhalation-type anti-clogging smoke detection device.
