[0002] Indoor environmental testing is a scientific activity that uses modern scientific and technological methods to quantitatively measure the concentration changes of environmental factors and other indoor environmental pollutants that are harmful to human health in an intermittent or continuous manner, and to observe and analyze the process and extent of their environmental impact. Urban residents in China account for less than half of the total population, but more than 270 million residents breathe substandard indoor air. People spend at least 80% of their lives indoors, less than 5% outdoors, and the rest of their time in between. Some people with limited mobility, the elderly, and infants may spend up to 95% of their time indoors, so the quality of indoor air is even more closely related to human health.

[0003] During the process of realizing the invention, the inventors discovered that at least the following problems existed in the prior art and were not solved: During the use of traditional indoor environment monitoring equipment, the monitoring data of indoor formaldehyde often had low accuracy due to dust in the air. Later, some indoor environment monitoring equipment added dust isolation components to isolate dust. However, due to the long-term accumulation of dust and the lack of timely cleaning, the dust isolation net became blocked, which reduced the amount of gas entering the monitoring equipment, resulting in low accuracy of indoor formaldehyde monitoring data. Therefore, it was necessary to design a new technical solution to solve this problem. Summary of the Invention

[0015] As a preferred embodiment of the present invention, a discharge port is provided on one side of the monitor body, and one end of the air stripping mechanism is sealedly connected to the inner wall of the monitor body and communicates with the interior of the discharge port.

[0016] As a preferred embodiment of the present invention, a sealing plate is rotatably connected to the inner wall of the discharge port, and the weight of the bottom end of the sealing plate is twice the weight of the upper end.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The air outlet of the air guide plate of the present invention is at a 45-degree angle to the bottom of the air stripping mechanism, so that the air outlet of the air guide plate can blow the gas toward the air stripping component at a 45-degree angle, and then cooperate with the wind shield to block the gas blowing toward the dust stripping net. At this time, the dust stripping net will have an upward thrust, and when the first spring is compressed to a certain extent, it will generate a rebound force, thereby allowing the air stripping component to swing back and forth inside the limit sleeve. In this process, due to the addition of the eccentric wheel, the air stripping component can swing back and forth stably, reducing the number of interruptions, so that the dust stripping net will shake during the process of the brush plate cleaning the dust stripping net, thereby increasing the cleanliness of the dust stripping net after cleaning, reducing the chance of the dust stripping net being blocked during use, and enhancing the smoothness and stability of the gas passing through the dust stripping net, which is beneficial to improving the accuracy of indoor environment monitoring equipment in monitoring indoor formaldehyde.

[0019] When the air stripping assembly vibrates back and forth up and down, the tooth plate will drive the ratchet to rotate (when the tooth plate moves downward, it will contact the ratchet. At this time, one end of the tooth plate will produce an extrusion force on the second spring, causing the tooth plate to shrink into the inside of the built-in groove, so as to prevent the ratchet from reversing). The ratchet will drive the driving shaft to rotate, and then the driving shaft will drive the first bevel gear to rotate, and then the first bevel gear will drive the transmission mechanism to rotate, and then the transmission mechanism will drive the connecting shaft together with the second fan blade through the second bevel gear to rotate. At this time, the second fan blade will blow the gas entering the other side of the air stripping assembly toward the conical vortex generating cover. At this time, the gas will generate a vortex inside the conical vortex generating cover and blow toward the formaldehyde monitoring sensor monitoring end in the monitoring room, and wrap the formaldehyde monitoring sensor monitoring end in the monitoring room, so that the gas can be fully detected by the formaldehyde monitoring sensor monitoring end, which is beneficial to improve the accuracy of the formaldehyde monitoring sensor monitoring end in monitoring formaldehyde in the gas.

[0020] The gas in the monitoring room will be discharged from the exhaust pipe after being monitored, and then discharged from the other end of the exhaust pipe. At this time, the gas will generate thrust on the first fan blade, so that the first fan blade will rotate. At this time, the first fan blade will generate wind force and blow the dust floating in the air stripping mechanism from the exhaust port to the outside of the monitor body. At the same time, when the first fan blade rotates, it will drive the eccentric wheel and the brush plate to rotate. At this time, the brush plate will clean the dust attached to the surface of the dust stripping net, thereby unblocking the dust stripping net, so that the gas can smoothly enter the monitoring room for monitoring, thereby realizing automatic cleaning of dust without using other driving mechanisms;

[0021] When the first fan blade rotates, it will generate an outward thrust on the sealing plate, so that the bottom end of the sealing plate will be separated from the exhaust port. At this time, the dust floating in the air stripping mechanism will be blown out to the outside, thereby preventing the dust from adhering to the dust stripping net and affecting the flow rate of the gas entering the monitoring room, thereby avoiding affecting the accuracy of the formaldehyde monitoring sensor in monitoring formaldehyde in the gas.

[0022] When the drive shaft rotates, it will drive the mounting wheel to rotate. At this time, the mounting wheel will stretch the three rubber bands through the eccentric mounting column, storing elastic potential energy. When the device starts to rotate, the degree of stretching of the rubber band will change with the change of angle. When one of the rubber bands rotates to a certain position, it begins to gradually relax, and the stored elastic potential energy is converted into kinetic energy for the rotation of the device, pushing the device to continue rotating. At the same time, the other rubber band begins to be stretched again, and the elastic potential energy is stored again. The mounting wheel and the eccentric mounting column are a non-centrally symmetrical disc. When it rotates, it will produce a "swinging" action, similar to a "nodding" action, thereby generating a periodic push-pull force. This push-pull force is transmitted to the fan blades through the connecting rod, causing them to swing left and right. When the wind force blown out of the exhaust pipe is relatively small, the drive shaft can be in a normal rotating state, thereby ensuring that the air stripping mechanism and the eddy current mechanism are always in operation, which is beneficial to improving the accuracy of indoor formaldehyde monitoring equipment in indoor environment monitoring.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0046] Example 1: An indoor environment monitoring device, see Figures 1 to 15 , including a monitor body 1, an air inlet 11 is opened at the bottom of the monitor body 1, the air inlet 11 at the bottom of the monitor body 1 is covered with an air intake fan 12, the air inlet 11 inside the monitor body 1 is covered with a gas collecting cover 13, and the other end of the gas collecting cover 13 is connected to an air guide component, which is used to change the angle of the gas when it enters the air stripping mechanism 2.

[0047] For details, see Figures 4 to 7 The air guide assembly includes an air guide plate 14, the other end of the air guide plate 14 passes through the through groove 24 of the air stripping mechanism 2 and extends to the interior of the air stripping mechanism 2. The air outlet of the air guide plate 14 is at a 45-degree angle to the bottom of the air stripping mechanism 2, so that the air outlet of the air guide plate 14 can blow the gas toward the air stripping assembly 23 at a 45-degree angle, thereby generating thrust on the air stripping assembly 23.

[0048] See also Figures 7 to 14 The top and bottom of the air stripping mechanism 2 are both connected and fixedly connected with a limiting sleeve 21. The interior of the two limiting sleeves 21 is connected with an air stripping component 23 through a first spring 22. The air stripping component 23 is used to strip dust in the air to prevent dust in the air from adhering to the monitoring end of the formaldehyde monitoring sensor 52 in the monitoring chamber 51, resulting in inaccurate monitoring of the formaldehyde content in the air.

[0049] For further information, see Figure 7 One end of the two first springs 22 rests on the inner walls of the two limiting sleeves 21, and the other ends of the two first springs 22 rest on the two ends of the air stripping assembly 23. The air stripping assembly 23 moves through the inner wall of the air stripping mechanism 2 and is slidably connected to the inner wall of the limiting sleeve 21. The air stripping assembly 23 is at a 45-degree angle to the bottom of the air stripping mechanism 2, so that the gas discharged from the air outlet of the air guide plate 14 can be fully blown to the air stripping assembly 23, and cooperates with the wind shield 32 to generate an upward thrust on the air stripping assembly 23, thereby squeezing the first spring 22, so that the first spring 22 generates a rebound force on the air stripping assembly 23 when it is subjected to the maximum compression force, thereby causing the air stripping assembly 23 to vibrate back and forth.

[0050] Further, see Figure 10 The air stripping component 23 includes a mounting frame 25. Three dust stripping nets 26 of the same size are installed between the mounting frame 25 and the inner ring of the air stripping component 23. The center of the mounting frame 25 is fixedly connected to a connecting shaft 49 bearing 27. The inner ring of the connecting shaft 49 bearing 27 is fixedly connected to a driving shaft 28. One end of the driving shaft 28 is fixedly connected to a brush plate 29. The end face of the driving shaft 28 close to the brush plate 29 is fixedly connected to the first fan blade 3. An eccentric wheel 31 is fixedly connected to the outside of the mounting shaft of the first fan blade 3. The first fan blade 3 is located on the side away from the air outlet of the air guide plate 14. A windshield 32 is fixedly connected to the upper side of one side of the air stripping component 23. The addition of the windshield 32 can block the gas blowing toward the dust stripping net 26. At this time, the dust The dust stripping net 26 will have an upward thrust. When the first spring 22 is compressed to a certain extent, a rebound force will be generated, allowing the air stripping component 23 to swing back and forth inside the limit sleeve 21. During this process, due to the addition of the eccentric wheel 31, the air stripping component 23 can swing back and forth stably, reducing the number of interruptions, so that the dust stripping net 26 is shaken during the brush plate 29 cleaning the dust stripping net 26, thereby increasing the cleanliness of the dust stripping net 26 after cleaning, reducing the probability of the dust stripping net 26 being blocked during use, and enhancing the smoothness and stability of the gas passing through the dust stripping net 26, which is beneficial to improving the accuracy of indoor environment monitoring equipment in monitoring indoor formaldehyde.

[0051] It is worth noting that, see Figure 9 、 Figure 10 and Figure 12The other end of the drive shaft 28 is fixedly connected to the center of the mounting wheel 33, and the edge of the other side of the mounting wheel 33 is fixedly connected to the eccentric mounting column 34. The eccentric mounting column 34 is sequentially sleeved with three rubber bands 35 of the same size from the outside to the inside. The other ends of the three rubber bands 35 are respectively installed on three limiting columns 36. The installation position of each limiting column 36 corresponds to the position where the rubber band 35 is installed on the eccentric mounting column 34. When the drive shaft 28 rotates, it will drive the mounting wheel 33 to rotate. At this time, the mounting wheel 33 will stretch the three rubber bands 35 through the eccentric mounting column 34, storing elastic potential energy. When the device starts to rotate, the degree of stretching of the rubber band 35 will change with the change of angle. When one of the rubber bands 35 is rotated to a certain position When the spring is fully extended, it begins to relax gradually, and the stored elastic potential energy is converted into kinetic energy for the rotation of the device, pushing the device to continue rotating. At the same time, the other rubber band 35 begins to be stretched again to store elastic potential energy again. The mounting wheel 33 and the eccentric mounting column 34 are a non-center symmetrical disc. When it rotates, it will produce a "swinging" action, similar to a "nodding" action, thereby generating a periodic push-pull force. This push-pull force is transmitted to the fan blades through the connecting rod, causing them to swing left and right. When the wind force blown out of the exhaust pipe 5 is relatively small, the drive shaft 28 can be in a normal rotating state, thereby ensuring that the air stripping mechanism 2 and the eddy current mechanism are always in operation, which is beneficial to improving the accuracy of indoor formaldehyde monitoring by indoor environment monitoring equipment.

[0052] See also Figure 6 、 Figure 10 、 Figure 14 and Figure 15 A vortex mechanism is installed on one side of the air stripping component 23. The vortex mechanism is used to form a vortex in the stripped gas to wrap the monitoring end of the formaldehyde monitoring sensor 52 located in the monitoring chamber 51, so that the formaldehyde monitoring sensor 52 in the monitoring chamber 51 can accurately monitor the formaldehyde in the gas.

[0053] The vortex mechanism includes a second fan blade 4 and a conical vortex generating cover 41. A built-in groove 42 is provided on the other side of the air stripping component 23. One end of the built-in groove 42 is rotatably connected to a tooth plate 43. The other end of the tooth plate 43 is fixedly connected to a second spring 44. The other end of the second spring 44 is fixedly connected to the inner wall of the built-in groove 42. The toothed end of the tooth plate 43 is engaged with a ratchet 45. A driving shaft 46 is fixedly connected to the middle of one side of the ratchet 45. The other end of the driving shaft 46 is fixedly connected to a first bevel gear 47. The wheel 47 is connected to the second bevel gear 48 through a transmission mechanism. The center of the second bevel gear 48 is fixedly connected to one end of the connecting shaft 49. The outer surface of the connecting shaft 49 is fixedly connected to the inner ring of the transmission bearing 38. The outer ring of the transmission bearing 38 is fixedly connected to the center of the carrier 37. The other end of the connecting shaft 49 is located on the other side of the carrier 37 and is fixedly connected to the mounting end of the second fan blade 4. When the air stripping component 23 vibrates up and down, the tooth plate 43 drives the ratchet 45 to rotate (the tooth plate 43 When it moves downward, it will contact the ratchet 45. At this time, one end of the tooth plate 43 will generate an extrusion force on the second spring 44, so that the tooth plate 43 will shrink into the inside of the built-in groove 42, so as to prevent the ratchet 45 from reversing). The ratchet 45 will drive the driving shaft 46 to rotate, and then the driving shaft 46 will drive the first bevel gear 47 to rotate, and then the first bevel gear 47 will drive the transmission mechanism to rotate, and then the transmission mechanism will drive the connecting shaft 49 together with the second fan blade 4 through the second bevel gear 48 to rotate. At this time, the second fan blade 4 will blow the gas entering the other side of the air stripping component 23 to the conical vortex generating cover 41. At this time, the gas will generate a vortex inside the conical vortex generating cover 41 and blow towards the monitoring end of the formaldehyde monitoring sensor 52 in the monitoring chamber 51, and wrap the monitoring end of the formaldehyde monitoring sensor 52 located in the monitoring chamber 51, so that the gas can be fully detected by the monitoring end of the formaldehyde monitoring sensor 52, which is beneficial to improve the accuracy of the monitoring end of the formaldehyde monitoring sensor 52 in monitoring formaldehyde in the gas.

[0054] It is worth noting that see Figure 7 and Figure 10 , the outer surface of the driving shaft 46 is rotated and connected to the inside of the carrier 37. The transmission mechanism includes two third bevel gears 39 and a connecting shaft. One end of the two third bevel gears 39 is fixedly connected to the two ends of the connecting shaft. One end of one third bevel gear 39 is engaged with the tooth end of the first bevel gear 47, and the other end of the other third bevel gear 39 is engaged with the tooth end of the second bevel gear 48. When the first bevel gear 47 rotates, it will drive one third bevel gear 39 to rotate. In this process, the connecting shaft will drive the other third bevel gear 39 to rotate, so that the third bevel gear 39 drives the second bevel gear 48 to rotate.

[0055] It is worth mentioning that see Figure 6 and Figure 8 The other end of the monitoring chamber 51 is sealed and connected to the exhaust pipe 5, and the other end of the exhaust pipe 5 extends to the interior of the air stripping mechanism 2 and is located on one side of the first fan blade 3. The gas in the monitoring chamber 51 will be discharged from the exhaust pipe 5 after being monitored, and then the gas will be discharged from the other end of the exhaust pipe 5. At this time, the gas will generate thrust on the first fan blade 3, thereby causing the first fan blade 3 to rotate. At this time, the first fan blade 3 will generate wind force and blow the dust floating in the air stripping mechanism 2 from the exhaust port 15 to the outside of the monitor body 1. At the same time, when the first fan blade 3 rotates, it will drive the eccentric wheel 31 and the brush plate 29 to rotate. At this time, the brush plate 29 will clean the dust attached to the surface of the dust stripping net 26, thereby clearing the dust stripping net 26, so that the gas can smoothly enter the monitoring chamber 51 for monitoring, thereby realizing automatic cleaning of dust without using other driving mechanisms.

[0056] It is worth emphasizing that see Figures 1 to 3 An exhaust port 15 is provided on one side of the monitor body 1. One end of the air stripping mechanism 2 is sealed and connected to the inner wall of the monitor body 1 and communicates with the interior of the exhaust port 15. When the first fan blade 3 rotates, it will generate an outward thrust on the sealing plate 16, so that the bottom end of the sealing plate 16 is separated from the exhaust port 15. At this time, the dust floating in the air stripping mechanism 2 will be blown out to the outside, thereby preventing the dust from adhering to the dust stripping net 26 and affecting the flow rate of the gas entering the monitoring chamber 51, thereby avoiding affecting the accuracy of the formaldehyde monitoring sensor 52 in monitoring formaldehyde in the gas;

[0057] The inner wall of the discharge port 15 is rotatably connected to a sealing plate 16. The weight of the bottom end of the sealing plate 16 is twice the weight of the upper end. The sealing plate 16 is designed to be heavy at the bottom and light at the top so that the sealing plate 16 can be in a vertical state under the action of a small external force, thereby blocking the discharge port 15.

[0058] It should be noted that the main component of the rubber band 35 is polyisoprene, which is a high molecular polymer. It has the characteristics of high elasticity, high tensile strength, good tear resistance and wear resistance.

[0059] The gravity of the eccentric wheel 31 is smaller than the driving force of the drive shaft 28. The first blade 3 and the second blade 4 are both made of lightweight plastic, which reduces the gravity of the first blade 3 and the second blade 4 and improves the rotation effect.

[0060] The dust stripping net 26 adopts a HEPA filter.

[0061] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
