Description

Technical Field

[0001] This invention relates to the field of smoke detector technology, and in particular to an inductive smoke detector alarm with self-cleaning heating function and its usage method. It effectively solves the problems of incomplete dehumidification and dust accumulation affecting detection in existing smoke detectors, maintaining the cleanliness and dryness of the inside of the smoke detector, ensuring detection accuracy and stability. It can be widely applied to security needs in power plants, power transmission and transformation, aerospace, shipbuilding, chemical, light industry, mining machinery, and other fields. It also extends the overall service life, reduces maintenance frequency and costs, lowers long-term investment, and ensures reliable operation, providing continuous and effective support for fire early warning and enhancing the practical security application value. Background Technology

[0002] Inductive smoke detectors are security devices that use smoke recognition technology in conjunction with the auxiliary verification of inductive components to achieve accurate identification and immediate alarm of smoke signals. They have the advantages of accurate detection, strong signal stability, and low false alarm rate, and are widely used in power plants, power transmission and transformation, aerospace, shipbuilding, chemical industry, light industry, mining machinery and other places.

[0003] Existing smoke detectors come in various models. For example, Chinese utility model patent CN208708050U discloses a heating base and an inductive smoke detector alarm including the heating base. The heating base includes a heating base body, a groove, a base fixing block, a base threaded hole, and a heating pad. The upper end of the heating base body has a groove, and a heating pad is placed inside the groove. Two base fixing blocks are provided on the outer edge of the heating base body, and each base fixing block has a base threaded hole.

[0004] To avoid the refraction of emitted light by air affecting the sensing effect and triggering the alarm signal, existing smoke and fire detectors use heating dehumidification to remove moisture from the detector. However, this dehumidification method results in the heated moisture still accumulating inside the detector, failing to completely remove the moisture.

[0005] For example, Chinese utility model patent CN208708050U discloses a heating base and an inductive smoke detector alarm including the heating base. The heating base includes a heating base body, a groove, a base fixing block, a base threaded hole, and a heating pad. The upper end of the heating base body has a groove, and the heating pad is placed inside the groove. Two base fixing blocks are provided on the outer edge of the heating base body, and each base fixing block has a base threaded hole. This alarm removes internal moisture by heating with a heating pad. This dehumidification method causes some moisture to accumulate on the inner wall of the alarm. After condensation, the moisture still remains inside the alarm, failing to achieve thorough dehumidification. Furthermore, this device cannot handle internal dust, and dust accumulation inside the alarm also affects the detection effect. Summary of the Invention

[0006] The purpose of this invention is to solve the problem that existing smoke detectors cannot effectively remove moisture and dust from their interiors, and to provide an inductive smoke detector with a self-cleaning heating function and its usage method, thereby achieving effective removal of moisture and dust from the interior of the smoke detector, and thus improving the sensing accuracy and long-term operational reliability of the smoke detector.

The dust is removed by the adsorption component and some moisture is adsorbed by the activated carbon adsorption plate to complete the initial dehumidification. S2. The gas after preliminary dehumidification is introduced into the heating unit, which completely evaporates the residual moisture in the gas to generate dry gas. S3. The heating unit returns the dry gas generated in step S2 to the inside of the inductive probe to complete the air replacement; at the same time, the heating unit discharges the condensed moisture inside it. S4. During the operation of the heating unit, some of the heat from the heating unit is transferred to the regeneration unit to heat the air inside the regeneration unit, forming hot air. After cleaning is completed, the hot air is injected into the activated carbon adsorption plate in the cleaning unit to desorb and regenerate the activated carbon adsorption plate.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects: By setting up a cleaning unit that includes an air intake component, a dust filter ramp, and an activated carbon adsorption plate, the dust and moisture inside the inductive probe are actively drawn out and subjected to physical filtration and adsorption treatment respectively. This solves the problem that existing technologies cannot remove dust and effectively avoids the decrease in detection accuracy caused by dust accumulation.

[0019] By setting up a heating unit that includes a conveying channel and a heating rack, the air after initial dehumidification is reheated, and the generated dry hot air is circulated back into the inductive probe through a return pipe. This achieves a thorough "displacement" removal of moisture, rather than simple internal heating and evaporation, thus solving the technical problem of incomplete dehumidification caused by secondary condensation of water vapor on the inner wall in existing technologies.

[0020] By setting up a regeneration unit that includes a heat-conducting roller and a regeneration gas pipe, the waste heat from the heating unit is cleverly utilized to perform hot air desorption and regeneration of the activated carbon adsorption plate. This not only saves energy but also extends the service life of the activated carbon adsorption plate, enabling long-term maintenance-free self-cleaning cyclic operation of the equipment and improving the practicality and economy of the device.

[0021] In summary, this invention solves the problem of moisture and dust interfering with the internal environment of inductive smoke detectors from the root through a closed-loop workflow of "dust suction and filtration - preliminary adsorption - deep heating - displacement return air - adsorbent regeneration", significantly improving the detection accuracy and environmental adaptability of the equipment.

[0030] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments.

[0031] This embodiment provides an inductive smoke detector alarm with self-cleaning heating function.

[0032] The alarm described in this embodiment includes an alarm body 2 disposed on the alarm base 1; the alarm body 2 is provided with an inductive probe 3 for detecting the external environment; the inductive probe 3 integrates a variety of sensing sensors, such as temperature sensors and smoke particle sensors, for real-time sensing of temperature changes or smoke particles in the external environment, and issuing an alarm when the temperature rises to a threshold or smoke particles are detected.

[0033] In this embodiment, the inductor probe 3 will absorb a lot of moisture and dust during long-term use, so it needs to be cleaned automatically on a regular basis. The inductor probe 3 is equipped with a humidity sensor to monitor the humidity inside the inductor probe 3 in real time. When the humidity exceeds the set threshold, the self-cleaning dehumidification program is triggered.

[0034] To address the issues of incomplete moisture removal and dust removal in existing technologies, this embodiment adds an internal box 4 inside the alarm body 2.

[0035] In this embodiment, the built-in box 4 integrates a cleaning unit, a heating unit, and a regeneration unit. The cleaning unit, heating unit, and regeneration unit work together to achieve automatic cleaning of the inductor probe 3, thereby removing moisture and dust from the inductor probe 3, keeping the inside of the inductor probe 3 clean and dry, improving its sensing sensitivity and accuracy, and avoiding false alarms.

[0036] In this embodiment, the cleaning unit is equipped with an activated carbon adsorption plate 18 for adsorbing moisture in the air. The cleaning unit is used to remove moisture and dust from the inductor probe 3 and to filter and separate the two. At the same time, the moisture in the air can be initially removed by the adsorption of the activated carbon adsorption plate 18, which can effectively prevent the accumulation of dust and moisture inside the inductor probe 3, keep the inside of the inductor probe 3 dry and clean, ensure that the detection function of the inductor probe 3 is not interfered with, and improve the detection accuracy of the inductor probe 3.

[0037] In this embodiment, the heating unit can heat and dehumidify the moisture adsorbed by the activated carbon adsorption plate 18, so that the moisture in the moisture is separated from the air to achieve thorough dehumidification. It can also guide the dry air back into the inductor probe 3 to complete the replacement of moisture and dry air in the inductor probe 3. At the same time, it can collect the separated moisture to avoid moisture residue affecting the dehumidification effect.

[0038] In this embodiment, the regeneration unit can utilize and convert heat during the heating and dehumidification process, and use this heat to heat the air so that it is blown onto the activated carbon adsorption plate 18 after dehumidification, thereby realizing the desorption and regeneration of the activated carbon adsorption plate 18. This can effectively extend the service life of the activated carbon adsorption plate 18, realize its recycling, achieve multiple self-cleaning and drying, and reduce the time for maintenance and replacement.

[0039] In this embodiment, the cleaning unit includes an air guiding component and an adsorption component. The air guiding component is provided with an air suction component 5 for adsorbing moisture and dust in the inductive probe 3, and the adsorption component is provided with an activated carbon adsorption plate 18 for adsorbing moisture in the air.

[0040] In this embodiment, the adsorption component includes: Servo motor 12 is fixedly installed at the bottom of the built-in box 4; A drive roller 13 is connected to the drive end of the servo motor 12 and extends into the cleaning box 8; the drive roller 13 is rotatably connected to the cleaning box 8. A fan impeller 20, fixedly mounted on the drive roller 13, is used to generate negative pressure suction in the cleaning box 8; Activated carbon adsorption plate 18 is installed inside the cleaning box 8 to adsorb moisture in the moisture. The impeller 20 is located below the activated carbon adsorption plate 18; When the humidity sensor inside the inductor probe 3 detects that the humidity inside the inductor probe 3 exceeds the set threshold, it will trigger the servo motor 12 to start dehumidification. When the servo motor 12 starts, it will drive the drive roller 13 and the impeller 20 on it to rotate. When the impeller 20 rotates, it will generate negative pressure suction in the cleaning box 8, and then adsorb the air from the external environment through negative pressure suction.

[0041] In this embodiment, the air guiding assembly includes: A cleaning box 8 is fixedly installed inside the built-in box 4; An air intake component 5 is fixedly connected to the upper part of the cleaning box 8 and is used to adsorb moisture and dust inside the inductive probe 3; an air intake tube for adsorbing moisture and dust inside the inductive probe 3 is fixedly connected between the air intake component 5 and the inductive probe 3. The negative pressure suction will act on the suction pipe through the suction component 5. That is, the negative pressure suction will simultaneously adsorb the moisture and dust in the inductor probe 3 into the cleaning box 8 through the suction pipe and the suction component 5, thereby completing the removal of moisture and dust in the inductor probe 3 and realizing the dehumidification and dust removal in the inductor probe 3.

[0042] In this embodiment, the lower part of the air intake 5 is provided with multiple air dissipation openings, which expand the air intake range of the moisture. The moisture and dust in the air intake 5 will diffuse into the cleaning box 8 through the air dissipation openings, thereby increasing the coverage of moisture and dust in the cleaning box 8 and improving its subsequent filtration and dehumidification efficiency.

[0043] In this embodiment, a dust filter 17 for filtering dust in the moisture is fixedly installed inside the cleaning box 8, and the dust filter 17 is located below the suction component 5; a push-pull frame 15 is slidably engaged inside the cleaning box 8, and the push-pull frame 15 is located below the dust filter 17; the activated carbon adsorption plate 18 is detachably engaged inside the push-pull frame 15. After the moisture and dust diffuse into the cleaning box 8, they will first come into contact with the dust filter plate 17. At this time, the dust filter plate 17 will filter the dust, preventing the dust from passing through the dust filter plate 17, while the moisture will continue to flow downward through the dust filter plate 17. As the moisture continues to descend, it comes into contact with the activated carbon adsorption plate 18. At this time, the activated carbon adsorption plate 18 will initially absorb the moisture in the moisture, thereby completing the initial dehumidification treatment of the moisture. After the initial dehumidification, the moisture will continue to descend through the activated carbon adsorption plate 18. The activated carbon adsorption plate 18 is engaged within the push-pull bracket 15, which can slide within the cleaning box 8. This allows the activated carbon adsorption plate 18 to be moved, facilitating its replacement.

[0044] In this embodiment, the alarm body 2, the built-in box 4, and the cleaning box 8 are all equipped with maintenance doors, which can be used to inspect the interior of the built-in box 4 and the cleaning box 8, and to clean and remove the dust on the dust filter inclined plate 17 inside the cleaning box 8.

[0045] In this embodiment, the heating unit includes a dehumidification component and a water collection component. The dehumidification component is provided with a first heating frame 23 and a second heating frame 33 for heating and evaporating the moisture in the humidity, and the two form a conveying channel for conducting the humidity. The water collection component is used to collect the evaporated moisture.

[0046] In this embodiment, the dehumidification component includes: A support plate 9 is fixedly installed inside the built-in box 4; A heating box 10 is fixedly installed on a support plate 9; Two support frames are fixedly installed inside the heating box 10; A first heating frame 23 and a second heating frame 33 are respectively fixedly installed on two support frames for heating and evaporating moisture in the air; the first heating frame 23 and the second heating frame 33 are spaced apart inside the heating box 10, forming a conveying channel for conducting moisture between them; A circulation mechanism is installed inside the heating box 10; the circulation mechanism includes a vent pipe 19 fixedly connected to the lower part of the cleaning box 8 for conducting moisture; After initial dehumidification in the cleaning box 8, the moisture will descend and be discharged through the air duct 19, completing the automatic conduction of moisture.

[0047] In this embodiment, the side wall of the heating box 10 is fixedly connected to the air inlet box 37 and the air return box 36. One end of the air inlet box 37 is connected to the air inlet end of the conveying channel, and the other end is connected to the lower part of the cleaning box 8 through the air guide pipe 19. One end of the return air box 36 is connected to the air outlet of the conveying channel, and the other end is connected to the inductive probe 3 through the return air pipe 6. Return pipe 6 is used to conduct dry air; Moisture in the air duct 19 enters the air inlet box 37 and then enters the conveying channel between the first heating frame 23 and the second heating frame 33 through the air inlet box 37. After gradually flowing in the conveying channel, it enters the return air box 36 and is discharged through the return air pipe 6. When the moisture flows between the first heating rack 23 and the second heating rack 33, the first heating rack 23 and the second heating rack 33 will start to heat the moisture efficiently, which can quickly evaporate the moisture in the moisture. The moisture is converted into water vapor, rises and adheres to the top of the heating box 10. At this time, the moisture in the moisture is removed and converted into dry hot air. The hot air will be conducted to the return air pipe 6 through the return air box 36. The dry, hot air in the return pipe 6 will rise and eventually return to the inductor probe 3, replenishing the air in the inductor probe 3 and expelling the remaining moisture, thus completing the replacement of moisture with dry air and achieving efficient dehumidification inside the inductor probe 3. The removed moisture will not accumulate inside the inductor probe 3, resulting in better dehumidification. Because the return air pipe 6 has a long stroke and its wall temperature is low, the heat inside the air is absorbed by the return air pipe 6 during the conduction of dry hot air, which can gradually cool the dry hot air and prevent the temperature of the dry air entering the inductive probe 3 from being too high, thereby avoiding false alarms from the temperature control element inside the inductive probe 3.

[0048] In this embodiment, the water collection assembly includes: A scraper 21 is slidably installed on the inner wall of the top of the heating box 10; a water guide plate 29 is fixedly installed on the lower part of the scraper 21; a plurality of water guide grooves 31 for guiding water flow are provided on the water guide plate 29; A water-carrying inclined plate 24 is installed on the inner wall of the bottom of the heating box 10 for collecting water; a drain pipe 25 is fixedly connected to the side wall of the heating box 10 at the lower position corresponding to the water-carrying inclined plate 24. The reciprocating mechanism installed between the wiper frame 21 and the drive roller 13 is used to drive the wiper frame 21 to move back and forth.

[0049] In this embodiment, the reciprocating mechanism includes: Two linkage rods 28 are fixedly installed on the side of the water inlet plate 29 and slidably connected to the side wall of the heating box 10; Two reset spring rods 30 connected between the side wall of the water inlet plate 29 and the inner wall of the heating box 10 for resetting; An incomplete gear 26 is fixedly mounted on the drive roller 13; A transmission gear plate 27 is fixedly installed on two linkage rods 28 and intermittently meshes with an incomplete gear 26; While the servo motor 12 drives the drive roller 13 to rotate, the rotation of the drive roller 13 will drive the incomplete gear 26 on it to rotate. The rotation of the incomplete gear 26 will intermittently mesh with the transmission gear plate 27. When the incomplete gear 26 meshes with the transmission gear plate 27, it will pull the transmission gear plate 27 to the left. When the transmission gear plate 27 moves to the left, it will pull the water guide plate 29 to the left through the two linkage rods 28. When the water guide plate 29 moves to the left, it will stretch the two return spring rods 30. When the incomplete gear 26 does not mesh with the transmission gear plate 27, the two return spring rods 30 will automatically retract and reset, thereby pulling the water guide plate 29 to the right. Then, through the two linkage rods 28, it will drive the transmission gear plate 27 to the right and reset. The continuous rotation of the incomplete gear 26 will repeat the above movement, realizing the reciprocating left and right movement of the transmission gear plate 27 and the water guide plate 29. When the water-guiding plate 29 moves back and forth, it will drive the scraper 21 to move back and forth on the top of the heating box 10. When the scraper 21 scrapes the top of the heating box 10, it will scrape off the water droplets that have condensed after dehumidification on the top of the heating box 10, and let the water droplets slide down the scraper 21 onto the water-guiding plate 29, and fall down onto the water-carrying inclined plate 24 along the water-guiding groove 31 on the water-guiding plate 29, thus completing the scraping and collection of water droplets on the top of the heating box 10, and the water can be discharged periodically through the drain pipe 25.

[0050] In this embodiment, the regeneration unit includes a pressurizing component and a ventilation component. The pressurizing component is provided with two heat-conducting rollers 32 for conducting heat within the heating unit, and the desorption and regeneration of the activated carbon adsorption plate 18 is achieved through the cooperation of the ventilation component.

[0051] In this embodiment, the pressurization component includes: The regeneration cylinder 11 is fixedly installed on the support plate 9; A heat absorption plate 34 is fixedly installed inside the regeneration cylinder 11; Two heat-conducting rollers 32 are fixedly installed between the second heating frame 33 and the heat-absorbing plate 34; one end of the heat-conducting roller 32 is in contact with the second heating frame 33, and the other end is in contact with the heat-absorbing plate 34. When the second heating frame 33 is heated, some of the heat generated will be conducted to the heat absorption plate 34 through the two heat-conducting rollers 32, thus completing the heat conduction and conversion.

[0052] In this embodiment, two heat-insulating sleeves 22 for heat preservation are fixedly installed between the regeneration cylinder 11 and the heating box 10; two heat-conducting rollers 32 are respectively located inside the two heat-insulating sleeves 22. The heat-insulating sleeves 22 are used to keep the heat-conducting rollers 32 warm, so that when the heat-conducting rollers 32 conduct heat, the heat on them will not be dissipated into the outside air, thus avoiding excessive heat dissipation and waste. A heat dissipation frame 35 for heat dissipation is fixedly installed on the heat absorption plate 34; an auxiliary heating plate is fixedly installed on the heat dissipation frame 35. The heat on the heat absorption plate 34 will be quickly dissipated into the air inside the regeneration cylinder 11 through the heat dissipation frame 35, and the air inside the regeneration cylinder 11 can be auxiliaryly heated by the auxiliary heating plate to improve the heating efficiency.

[0053] In this embodiment, the ventilation component includes: A regeneration gas pipe 14 is fixedly connected between the regeneration cylinder 11 and the cleaning box 8; one end of the regeneration gas pipe 14 is connected to the regeneration cylinder 11 and the other end is connected to the cleaning box 8. The air inside the regeneration cylinder 11 will gradually expand when heated. When the dehumidification process in the inductive probe 3 is completed and self-cleaning is finished, the air inside the regeneration cylinder 11 is heated. At this time, the regeneration air pipe 14 can be opened so that the expanded hot air inside the regeneration cylinder 11 can be quickly rushed into the cleaning box 8 through the regeneration air pipe 14 to complete the conduction of hot air.

[0054] In this embodiment, the outlet of the regeneration gas pipe 14 is located below the activated carbon adsorption plate 18. After the expanding hot air enters the cleaning box 8, it will directly contact the activated carbon adsorption plate 18 to increase the temperature of the activated carbon adsorption plate 18, thereby destroying the adsorption force between the activated carbon and water molecules inside it. This causes the originally adsorbed water molecules to detach from the pores of the activated carbon and flow synchronously with the hot air flow, leaving the activated carbon adsorption plate 18. This completes the desorption and regeneration of water in the activated carbon adsorption plate 18, which can effectively extend the service life of the activated carbon adsorption plate 18, realize its recycling, achieve multiple self-cleaning and drying, and reduce the maintenance and replacement time.

[0055] In this embodiment, the regeneration cylinder 11 is fixedly connected to an air exchange pipe 7 for replenishing air, and multiple air exchange holes are opened on both the built-in box 4 and the alarm body 2. The cleaning box 8 is fixedly connected to an exhaust pipe 16 for exhausting air, and the interface position of the exhaust pipe 16 is higher than the activated carbon adsorption plate 18. After heating and regeneration, the air containing moisture will be discharged into the built-in box 4 through the exhaust pipe 16, and discharged to the outside of the alarm body 2 through multiple ventilation holes, thus completing the automatic discharge of moisture. After the hot air in the regeneration cylinder 11 is discharged, the ventilation pipe 7 is opened to allow the outside air to be automatically pressed into the regeneration cylinder 11, thus replenishing the air in the regeneration cylinder 11 and facilitating the next heating and regeneration process.

[0056] The self-cleaning working principle of the inductive smoke alarm of the present invention is as follows: When the humidity sensor inside the inductor probe 3 detects that the humidity inside the inductor probe 3 exceeds the set threshold, it triggers the servo motor 12 to start and drives the impeller 20 to rotate through the drive roller 13. When the impeller 20 rotates, it will generate negative pressure suction in the cleaning box 8. The moisture and dust inside the inductor probe 3 will be simultaneously adsorbed into the cleaning box 8 through the suction pipe and suction component 5, thus completing the removal of moisture and dust from the inductor probe 3.

[0057] After the moisture and dust diffuse into the cleaning chamber 8, they first come into contact with the dust filter plate 17. At this time, the dust filter plate 17 filters the dust, preventing it from passing through. The moisture then flows downward through the dust filter plate 17 and comes into contact with the activated carbon adsorption plate 18. The activated carbon adsorption plate 18 then absorbs the moisture in the moisture, thus completing the initial dehumidification treatment.

[0058] After initial dehumidification, the moisture enters the conveying channel between the first heating frame 23 and the second heating frame 33 through the air guide pipe 19 and the air inlet box 37. As the moisture flows in the conveying channel, the first heating frame 23 and the second heating frame 33 will start heating the moisture, rapidly evaporating the water in the moisture. At this time, the moisture in the moisture is removed and transformed into dry hot air. The hot air will then be conducted to the return air pipe 6 through the return air box 36. The dry hot air in the return air pipe 6 will rise and eventually return to the inductor probe 3, replenishing the air in the inductor probe 3 and expelling the remaining moisture, completing the replacement of moisture with dry air, and achieving efficient dehumidification inside the inductor probe 3.

[0059] When the second heating frame 33 heats up, some of the heat generated will be conducted to the heat absorption plate 34 through the two heat-conducting rollers 32. The heat on the heat absorption plate 34 will be quickly dissipated into the air inside the regeneration cylinder 11 through the heat dissipation frame 35, and the air inside the regeneration cylinder 11 can be further heated by the auxiliary heating plate.

[0060] The air inside the regeneration cylinder 11 gradually expands as it is heated. When the dehumidification process in the inductive probe 3 is completed and self-cleaning is finished, the air inside the regeneration cylinder 11 is heated and the regeneration air pipe 14 is opened. This allows the expanded hot air inside the regeneration cylinder 11 to rush into the cleaning chamber 8 through the regeneration air pipe 14. After entering the cleaning chamber 8, the expanded hot air will directly contact the activated carbon adsorption plate 18, completing the heating, desorption, and regeneration of the activated carbon adsorption plate 18, extending the service life of the activated carbon adsorption plate 18, and realizing its recycling.

[0061] This embodiment also provides a method for using an inductive smoke detector with a self-cleaning heating function, which includes the following steps: S1. During self-cleaning and dehumidification, the air guide component is activated to remove moisture and dust from the inductive probe 3 through the air intake component 5, and the dust is filtered and removed through the adsorption component. S2, and achieves preliminary removal of moisture in the moisture through the cooperation of activated carbon adsorption plate 18 in the adsorption component, and conducts the preliminarily dehumidified moisture to the heating unit. S3. Moisture is transported through the conveying channel in the dehumidification component and is converted into dry air after being heated by the first heating frame 23 and the second heating frame 33. The dry air returns to the inductor probe 3, completing the dehumidification and dust removal purification of the inductor probe 3. S4. When the heating unit heats up, some of the heat is conducted to the pressurizing component through the heat-conducting roller 32. After heating the air in the pressurizing component, it is injected into the air guiding component through the ventilation component to realize the desorption and regeneration of the activated carbon adsorption plate 18.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
