Description

Technical Field

[0001] This invention relates to the technical field of monitoring and alarm, specifically to an alarm device for monitoring air quality in gardens. Background Technology

[0002] Air pollution alerts refer to the process of measuring the types and concentrations of pollutants in the atmosphere and observing their spatial and temporal distribution and variation patterns. When the concentration of pollutants is higher than normal, an alert will be issued. Especially in garden environments, air quality has a crucial impact on the growth of plants and the health experience of visitors.

[0003] An air monitoring and alarm device described in the prior art includes a monitoring alarm, a pump suction cylinder fixedly installed at the upper end of the monitoring alarm, and a signal antenna fixedly installed on one outer wall of the monitoring alarm. It can periodically switch and clean the filter components to avoid the problem of the filter components becoming clogged after a period of use, which would affect the air intake monitoring work. It can also automatically replace the power supply module when the monitoring alarm is operating with low power.

[0004] While the aforementioned technologies can time-switch and filter components to prevent clogging and ensure proper intake monitoring, their application in garden environments presents challenges. Gardens typically have dense vegetation and abundant water, resulting in high humidity. This persistently damp environment can negatively impact the delicate electronic components inside the air monitor, leading to sensor reading deviations or inaccurate monitoring data. Furthermore, gardens, being biodiverse environments, are frequented by small flying insects such as mosquitoes. These insects can enter the instrument through ventilation holes or interface gaps, potentially interfering with the normal operation of optical sensors, causing short circuits, mechanical jamming, and other malfunctions. Ultimately, this affects the long-term stable operation of the equipment and the reliability of the monitoring results. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide an alarm device for monitoring air quality in gardens, in order to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An alarm device for monitoring air quality in gardens includes a monitoring alarm and an air monitor. The monitoring alarm has an internal mounting cavity, and the air monitor is fixed in the mounting cavity with screws. A suction pump is fixed to the inner wall of the mounting cavity with screws. The output port of the suction pump is connected to the air monitor through a conduit. The suction port of the suction pump is connected to a suction bend pipe that extends out of the top of the monitoring alarm. A dehumidification box is detachably installed at the bend of the suction bend pipe. The dehumidification box has a horizontal annular moisture absorption cylinder inside. The cylinder wall of the annular moisture absorption cylinder is a mesh structure and filled with spherical desiccant. A heating wire is installed inside the dehumidification box at the inner ring of the annular moisture absorption cylinder. The bottom wall of the dehumidification box is connected to an air intake pipe, and the outer surface of the air intake pipe is covered with a protective cover for insect prevention. The side wall of the dehumidification chamber is fitted with a protective shell by screws, and the bottom of the protective shell is fitted with a protective shell by screws. The protective shell is equipped with a rotating assembly. The two ends of the annular moisture-absorbing cylinder are respectively provided with a first annular plate and a second annular plate that penetrate the side wall of the dehumidification chamber. The outer ring of the second annular plate is fixed with a toothed ring. The rotating assembly matches the toothed ring and is used to control the rotation of the annular moisture-absorbing cylinder to dry the spherical desiccant inside through the heating wire.

[0007] Specifically, the outer wall of the annular moisture-absorbing cylinder is symmetrically provided with overlapping blocks. One side of each of the two overlapping blocks is provided with an arc surface that matches the outer wall of the annular moisture-absorbing cylinder. The other side of each of the two overlapping blocks is fixedly connected to the inner wall of the dehumidification box by screws. Both ends of the heating wire are fixedly connected to the inner wall of the dehumidification box. A temperature sensor is installed on the outer side of one end of the heating wire.

[0008] Specifically, in this technical solution, the rotating component includes a drive motor, which is fixed to the top of the inner wall of the protective shell by screws. A drive gear is fixed to the outer wall of the output end of the drive motor. The lower tooth surface of the drive gear meshes with the upper tooth surface of the gear ring. The first annular plate and the second annular plate are rotatably connected through bearings at the point where they pass through the dehumidification box.

[0009] Specifically, in this technical solution, a driven gear is meshed with the lower tooth surface of the gear ring. A rotating shaft is fixedly inserted at the center of the driven gear. Both ends of the rotating shaft are rotatably connected to the inner wall of the protective shell. A first transmission wheel is fixedly installed on the outer wall of the rotating shaft on one side of the driven gear. A transmission shaft is rotatably installed at the inner bottom of the protective shell. A second transmission wheel is fixedly installed on the outer wall of the transmission shaft. The first transmission wheel and the second transmission wheel are connected by a transmission chain. A perforation is opened in the protective shell and the shell wall at the transmission chain.

[0010] Specifically, in this technical solution, a discharge hole is provided on one side of the end face of the first annular plate, and a sealing plug is inserted into the discharge hole. The end of the sealing plug located outside the discharge hole is fixedly connected to the end face of the first annular plate by a screw, and the width of the discharge hole is greater than the diameter of the spherical desiccant.

[0011] Specifically, the protective cover is square with a central opening. The diameter of the opening is the same as the diameter of the air intake pipe. An insect-proof net is installed at the bottom opening of the protective cover. Side plates are symmetrically fixed on both sides of the bottom of the dehumidification box. Baffles are fixed on the walls of both side plates. The lower surfaces of both baffles are in contact with the top wall of the protective cover. Both side plates are fixedly connected to the outer wall of the protective cover by through-threaded screws.

[0012] Specifically, in this technical solution, a shaft is rotatably installed inside the opening of the protective cover above the insect-proof net. Three cams are fixed on the outer wall of the shaft. One end of the shaft extends through the protective cover to the outside, and a limiting plate is integrally fixed on the outer end face of the shaft. One end of the rotating shaft in the rotating assembly penetrates the protective shell, and a limiting groove matching the limiting plate is opened on the end face.

[0013] Specifically, in this technical solution, camphor ball placement slots are provided at the four corners of the top of the protective cover, and several ventilation holes are provided on the outer wall of the protective cover at the camphor ball placement slots, with all of the ventilation holes tilted downwards.

[0014] Specifically, in this technical solution, four sealing rods are fixed on the lower surface of the dehumidification box around the air intake pipe. The bottom of each of the four sealing rods matches the corresponding mothball placement groove, and the outer wall of each of the four sealing rods is bonded with a rubber layer.

[0015] Specifically, in this technical solution, the outer wall of the elbow of the suction bend is symmetrically fixed with ear plates, and the top of the dehumidification box is fixed with bolts on both sides of the insertion hole. Both bolts pass through the ear plates and are fixed with nuts.

[0016] In summary, the present invention has the following advantages: by setting up a downward-facing suction tube, an annular moisture-absorbing cylinder, and a spherical desiccant, it can effectively remove moisture from the intake air, avoid damage to the air monitoring instrument caused by water vapor, and improve the accuracy of monitoring data. At the same time, the rotating component can control the annular moisture-absorbing cylinder to rotate slowly, and work with the heating wire to dry the spherical desiccant, realizing the recycling of the desiccant and reducing the operating cost of the equipment. The protective cover is designed to prevent insects and impurities from entering the air intake pipe and affecting air circulation and monitoring. The insect net can block most flying insects, and the camphor balls placed in the mothball storage tank release their scent through the ventilation holes, further enhancing the insect-repelling effect. The downward-sloping ventilation holes prevent rainwater from entering, and the rotating component drives the shaft and cam. The rotating cam strikes the insect net, automatically cleaning insect carcasses and impurities and generating vibrations. These vibrations are transmitted through the protective cover to create a deterrent effect, further preventing insects from gathering on the insect net. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of the present invention will now be described.

[0021] It should be noted that the monitoring alarm 1 is the core control part of the entire alarm device. It not only provides a stable installation environment for the air monitor 102, but also integrates important components such as the suction pump 103 to ensure that air can be smoothly extracted and delivered to the air monitor 102 for detection. In actual operation, the monitoring alarm 1 will receive the monitoring data fed back by the air monitor 102 in real time and make judgments based on preset thresholds. When the concentration of pollutants in the air exceeds the normal range, the monitoring alarm 1 will quickly issue an alarm signal to remind relevant personnel to take appropriate measures. At the same time, the monitoring alarm 1 also has data storage and transmission functions, which can record and save the monitoring data for subsequent data analysis and processing.

[0022] In addition, the monitoring alarm 1 can also be connected to an external monitoring system to achieve remote monitoring and management. Through network communication technology, relevant personnel can obtain the operating status and monitoring data of the equipment in real time, promptly identify and resolve potential problems, and improve the operating efficiency and management level of the equipment.

[0023] In this embodiment, please refer to Figure 1 - Figure 8 As shown, an alarm device for monitoring air quality in a garden includes a monitoring alarm 1 and an air monitor 102. The monitoring alarm 1 has an internal mounting cavity 101. The air monitor 102 is fixed in the mounting cavity 101 with screws. A suction pump 103 is fixed to the inner wall of the mounting cavity 101 with screws. The output port of the suction pump 103 is connected to the air monitor 102 through a conduit 1031. The suction port of the suction pump 103 is connected to a suction bend 1032 that extends out of the top of the monitoring alarm 1. Ear plates 1033 are symmetrically fixed to the outer wall of the bend of the suction bend 1032. Bolts 205 are fixed on both sides of the insertion hole 201 at the top of the dehumidification box 2. Both bolts 205 penetrate the ear plates 1033 and are fixed with nuts, thereby realizing the detachable connection between the dehumidification box 2 and the suction bend 1032, which facilitates subsequent inspection and maintenance. The dehumidification chamber 2 contains a horizontal annular moisture-absorbing cylinder 4. The cylinder wall of the annular moisture-absorbing cylinder 4 has a mesh structure and is filled with spherical desiccant 403. A heating wire 5 is installed inside the annular moisture-absorbing cylinder 4. The outer wall of the annular moisture-absorbing cylinder 4 is symmetrically provided with overlapping blocks 208. One side of each overlapping block 208 has an arc surface that matches the outer wall of the annular moisture-absorbing cylinder 4. The other side of each overlapping block 208 is fixedly connected to the inner wall of the dehumidification chamber 2 with screws. The overlapping blocks 208 provide stable support for the annular moisture-absorbing cylinder 4. Both ends of the heating wire 5 are fixedly connected to the inner wall of the dehumidification chamber 2. A temperature sensor is installed on one side of the first annular plate 401 to monitor the heating temperature in real time and prevent the spherical desiccant 403 from being damaged by excessive temperature. A discharge hole 4011 is opened on one side of the end face of the first annular plate 401. A sealing plug 404 is inserted into the discharge hole 4011. The end of the sealing plug 404 located outside the discharge hole 4011 is fixedly connected to the end face of the first annular plate 401 by screws. The width of the discharge hole 4011 is greater than the diameter of the spherical desiccant 403. When the spherical desiccant 403 reaches the end of its service life, the sealing plug 404 can be removed to discharge the ineffective spherical desiccant 403 and then a new spherical desiccant 403 can be added. The bottom wall of the dehumidifier box 2 is connected to an air intake pipe 202. An insect-proof protective cover 3 is fitted over the air intake pipe 202. The protective cover 3 is square with a central opening. The diameter of the opening in the protective cover 3 is the same as the diameter of the air intake pipe 202. An insect-proof net 302 is installed at the bottom opening of the protective cover 3 to physically intercept flying insects and impurities. Side plates 206 are symmetrically fixed to both sides of the bottom of the dehumidifier box 2. Baffles 2062 are fixed to the walls of both side plates 206. The lower surfaces of both baffles 2062 are in contact with the top wall of the protective cover 3. Both side plates 206 are fixedly connected to the outer wall of the protective cover 3 by through-bolts 2061, ensuring the secure installation of the protective cover 3. The top four corners of the cover 3 are provided with camphor ball placement slots 301. The outer wall of the protective cover 3 is provided with several ventilation holes 3011 at the camphor ball placement slots 301. The ventilation holes 3011 are all inclined downwards, so camphor balls can be placed in the camphor ball placement slots 301. The camphor smell diffuses directionally around the inlet of the suction pipe 202 through the ventilation holes 3011, forming an odor repellency barrier. The lower surface of the dehumidification box 2 is fixed with four sealing rods 207 around the suction pipe 202. The bottom of the four sealing rods 207 matches the corresponding camphor ball placement slots 301. The outer wall of the four sealing rods 207 is bonded with a rubber layer, which can seal the camphor ball placement slots 301. A protective shell 203 is installed on the side wall of the dehumidification chamber 2 by screws, and a protective shell 204 is installed on the bottom of the protective shell 203 by screws. A rotating component 6 is provided inside the protective shell 203. A first annular plate 401 and a second annular plate 402 are respectively provided at both ends of the annular moisture absorption cylinder 4, which penetrate the side wall of the dehumidification chamber 2. A toothed ring 4021 is fixed on the outer ring of the second annular plate 402. The rotating component 6 is matched with the toothed ring 4021, and the rotating component 6 is used to control the rotation of the annular moisture absorption cylinder 4. The spherical desiccant 403 inside is dried by the heating wire 5.

[0024] When the equipment is started to monitor the air in the garden, the suction pump 103 starts to work. The suction force is applied to the dehumidification box 2 through the suction bend 1032, so that air enters through the suction pipe 202. The air first passes through the insect-proof net 302 at the bottom of the protective cover 3, and flying insects and impurities are physically intercepted. At the same time, the camphor odor in the camphor ball placement slot 301 diffuses through the vent 3011, which repels flying insects near the opening of the suction pipe 202 and reduces the probability of flying insects hitting the insect-proof net 302. The core targets of garden air monitoring are particulate matter (PM2.5, PM10) and gaseous pollutants (formaldehyde, VOCs, sulfur dioxide, etc.). The odor component emitted by the camphor balls is camphor, which is not within the range of pollutant indicators of conventional air monitoring. Even if a very small amount of camphor odor enters the suction pipe 202 due to airflow disturbance, the air monitor 102 will not identify or detect it, and there will be no false alarm or data distortion. Next, the air entering the suction pipe 202 passes through the annular desiccant 4. Through the mesh wall, the air comes into contact with the spherical desiccant 403 inside. The moisture in the air is adsorbed by the spherical desiccant 403, achieving air dehumidification. The dehumidified and dried air enters the air monitor 102 through the suction bend 1032 and the duct 1031 for pollutant concentration detection. During the air extraction process, the rotating component 6 is also activated. The drive motor 601 controls the annular desiccant 4 to rotate slowly, so that the spherical desiccant 403 inside the annular desiccant 4 comes into uniform contact with the moisture. At the same time, when the annular desiccant 4 rotates, the spherical desiccant 403 inside will roll and change position. Meanwhile, the heating wire 5 works, and the temperature sensor monitors the heating temperature in real time to ensure that the spherical desiccant 403 is dried at a suitable temperature, realizing the recycling of the desiccant. When the spherical desiccant 403 in the annular moisture absorption cylinder 4 reaches the end of its service life and can no longer effectively absorb moisture, the air humidity sensor (which can be integrated into the air monitor 102) will detect that the air humidity entering the air monitor 102 exceeds the standard, and the monitoring alarm 1 will also issue an alarm signal to remind the staff to replace the spherical desiccant 403. When the air monitor 102 detects that the concentration of pollutants in the garden air exceeds the preset threshold, it will transmit the signal to the monitoring alarm 1. The monitoring alarm 1 will quickly issue an alarm signal to remind relevant personnel to take corresponding measures. At the same time, the monitoring alarm 1 will record and save the monitoring data for subsequent data analysis and processing. If the equipment needs to be inspected and maintained, the screw 2061 can be disassembled first, the protective cover 3 can be removed from the suction pipe 202, and then the nut can be unscrewed to separate the dehumidification box 2 from the suction bend 1032. Then, each component can be inspected and repaired. The operation is relatively simple and can quickly complete the disassembly work, reducing the time cost of inspection and maintenance. When the spherical desiccant 403 reaches the end of its service life, the sealing plug 404 can be removed to discharge the ineffective spherical desiccant 403, and then new spherical desiccant 403 can be added. This effectively removes moisture from the inhaled air, preventing water vapor from damaging the air monitor 102 and improving the accuracy of the monitoring data. At the same time, it controls the annular moisture absorption cylinder 4 to rotate slowly, working with the heating wire 5 to dry the spherical desiccant 403, realizing the recycling of the desiccant and reducing the operating cost of the equipment.

[0025] Please see Figure 5 and Figure 7 As shown, the rotating assembly 6 includes a drive motor 601, which is fixed to the top of the inner wall of the protective shell 203 by screws. A drive gear 6011 is fixed to the outer wall of the output end of the drive motor 601. The lower tooth surface of the drive gear 6011 meshes with the upper tooth surface of the gear ring 4021. The first annular plate 401 and the second annular plate 402 are rotatably connected through bearings at the points where they pass through the dehumidification box 2. A driven gear 602 meshes with the lower tooth surface of the gear ring 4021. A rotating gear is fixedly inserted through the center of the driven gear 602. Shaft 603, both ends of which are rotatably connected to the inner wall of protective shell 203. The outer wall of shaft 603 is fixedly mounted with a first transmission wheel 6031 on one side of driven gear 602. The inner bottom of protective shell 204 is rotatably mounted with transmission shaft 604. The outer wall of transmission shaft 604 is fixedly mounted with a second transmission wheel 6041. The first transmission wheel 6031 and the second transmission wheel 6041 are connected by transmission chain 605. The shell walls of protective shell 203 and protective shell 204 are perforated at the transmission chain 605. Inside the opening of the protective cover 3, a shaft 303 is rotatably mounted above the insect net 302. Three cams 3031 are fixed on the outer wall of the shaft 303. One end of the shaft 303 extends through the protective cover 3 to the outside, and a limiting plate 3032 is integrally fixed on the outer end face of the shaft 303. One end of the rotating shaft 603 in the rotating assembly 6 passes through the protective shell 204, and a limiting groove matching the limiting plate 3032 is opened on the end face.

[0026] While the suction pump 103 is working, the drive motor 601 in the rotating assembly 6 starts. The output end of the drive motor 601 drives the drive gear 6011 to rotate. The drive gear 6011 drives the meshing gear ring 4021 to rotate, which in turn drives the annular moisture-absorbing cylinder 4 to rotate slowly through the second annular plate 402. At this time, the rotation of the gear ring 4021 will also drive the meshing driven gear 602 below to rotate, so that the rotating shaft 603 will rotate accordingly. The first transmission wheel 6031 on the rotating shaft 603 drives the second transmission wheel 6041 on the transmission shaft 604 to rotate through the transmission chain 605. At this time, due to the installation of the protective cover 3, the limiting plate 3032 at one end of the shaft 303 will be inserted into the limiting groove at one end of the transmission shaft 604 to form a linkage structure, so that the shaft 303 rotates synchronously with the transmission shaft 604. When the shaft 303 rotates, the three cams 3031 on its outer wall will also rotate accordingly. The rotation of these three cams 3031 will cause periodic impacts and vibrations to the insect net 302.

[0027] When the cam 3031 rotates to contact and squeeze the insect net 302, it will cause the insect net 302 to deform and vibrate. The flying insects and impurities that are intercepted on the insect net 302 will fall off due to this vibration, thus preventing the flying insects and impurities from accumulating too much on the insect net 302, thereby ensuring the breathability and interception effect of the insect net 302.

[0028] The working principle of this invention is as follows: When the equipment is started to monitor the air in the garden, the suction pump 103 starts to work, and the suction force is applied to the dehumidification box 2 through the suction bend 1032, so that the air enters through the air intake pipe 202. The air first passes through the insect-proof net 302 at the bottom of the protective cover 3, and flying insects and impurities are physically intercepted. At the same time, the camphor odor in the camphor ball placement slot 301 diffuses through the vent 3011, which repels flying insects near the opening of the air intake pipe 202 and reduces the probability of flying insects hitting the insect-proof net 302. The core target of garden air monitoring is particulate matter and gaseous pollutants. The odor component emitted by the camphor balls is camphor, which is not within the range of pollutant indicators of conventional air monitoring. Even if a very small amount of camphor odor enters the air intake pipe 202 due to airflow disturbance, the air monitor 102 will not identify and detect it, and there will be no false alarm or data distortion. Next, the air entering the suction pipe 202 passes through the annular moisture-absorbing cylinder 4. Through the mesh wall, the air comes into contact with the spherical desiccant 403 inside. The moisture in the air is adsorbed by the spherical desiccant 403, achieving air dehumidification. The dehumidified dry air then enters the air monitor 102 through the suction bend 1032 and the conduit 1031 for pollutant concentration detection. During the air extraction process, the rotating component 6 is also activated, driving the motor 601. Its output drives the drive gear 6011 to rotate, which in turn drives the meshing gear ring 4021 to rotate. This, in turn, drives the annular moisture-absorbing cylinder 4 to rotate slowly through the second annular plate 402. The rotation of the gear ring 4021 will also drive the driven gear 602 below to rotate, causing the shaft 603 to rotate as well. The first transmission wheel 6031 on the shaft 603 drives the second transmission wheel 6041 on the transmission shaft 604 to rotate through the transmission chain 605. At this time, due to the installation of the protective cover 3, the limiting plate 3032 at one end of the shaft 303 will be inserted into the limiting groove at one end of the transmission shaft 604, forming a linkage structure, so that the shaft 303 rotates synchronously with the transmission shaft 604. When the shaft 303 rotates, the three cams 3031 on its outer wall will also rotate. The rotation of these three cams 3031 will cause periodic impacts and vibrations to the insect net 302.

[0029] When the cam 3031 rotates to contact and squeeze the insect net 302, it will cause the insect net 302 to deform and vibrate. The flying insects and impurities that are intercepted on the insect net 302 will fall off due to this vibration, thus preventing the flying insects and impurities from accumulating too much on the insect net 302. During the rotation of the annular desiccant 4, the spherical desiccant 403 inside will come into uniform contact with the water vapor and will also roll and change position. At the same time, the heating wire 5 works, and the temperature sensor monitors the heating temperature in real time to ensure that the spherical desiccant 403 is dried at a suitable temperature. When the air monitor 102 detects that the concentration of pollutants in the garden air exceeds the preset threshold, it will transmit the signal to the monitoring alarm 1. The monitoring alarm 1 will quickly issue an alarm signal to remind relevant personnel to take appropriate measures.
