[0002] As people pay more and more attention to air quality, various air quality detection instruments emerge in an endless stream, such as air particle detection equipment. When air particle detection equipment detects the concentration of particles in the air, it uses a small fan in the air intake pipe to generate suction, so that the outside air is sucked into the air intake pipe, and then input into the laser particle detector through the air intake pipe. The laser light source is emitted by the diode in the laser particle detector. The focused light beam passes through a three-dimensional detection cavity. During the process of traveling, the light will encounter particles in the air and scatter. The scattered light changes its direction and is captured by the photometer. The photometer measures its luminous flux to calculate the concentration and mass of the particles in the air.

During the use of the existing environmental air quality detection device, dust particles in the air are easily attached to the pipe and the surface of the fan blade, which causes the dust particles on the pipe and the surface of the fan blade to fall off easily when the air in different environments is subsequently detected, resulting in the problem of inaccurate detection results; 2.

[0020] like Figures 1 to 13As shown, an environmental air quality detection device described in an embodiment of the present invention includes a detection body 1, one side of the inner wall of the detection body 1 is fixedly connected to a limiting shell 2, the top of one side of the inner wall of the limiting shell 2 is fixedly connected to an air intake pipe 3, and one end of the outer wall of the air intake pipe 3 is fixedly connected to the top of one side of the outer wall of the detection body 1, the inner wall of the limiting shell 2 is slidably connected to a plasma fan 4, one end of the outer wall of the plasma fan 4 is fixedly connected to a fixing frame 5, and the inner wall of the fixing frame 5 is slidably connected to an air guide bin 6, one end of the outer wall of the fixing frame 5 is fixedly connected to an exhaust pipe 7, and one end of the exhaust pipe 7 is overlapped with one end of the air guide bin 6, and the middle part of the outer wall of the exhaust pipe 7 is rotatably connected to a support frame 8, the middle part of one side of the inner wall of the detection body 1 is fixedly connected to a support plate 9, and the support The inner wall of the plate 9 is rotatably connected to a limit tube 10, and one end of the limit tube 10 is fixedly connected to the center of one side of the outer wall of the support frame 8, the top of the support plate 9 is fixedly connected to a laser particle detector 11, and the input end of the laser particle detector 11 is installed with a fitting mechanism, the bottom of one side of the inner wall of the detection body 1 is fixedly connected to an exhaust bin 12, and both sides of the outer wall of the exhaust bin 12 are fixedly connected to liquid storage bins 13, and the top of the exhaust bin 12 is fixedly connected to a water storage bin 14, the two ends of the inner wall of the detection body 1 away from the exhaust bin 12 are fixedly connected to cleaning bins 15, and one end of the top of the cleaning bin 15 is fixedly connected to one end of the bottom of the limit shell 2, and one side of the outer wall of the cleaning bin 15 is provided with a cleaning mechanism, and an adjustment mechanism is provided at the center of one side of the outer wall of the detection body 1;During operation, the detection body 1 is moved to the detection point, and the turntable 16 arranged at the center of one side of the outer wall of the detection body 1 is pushed, so that the fixing rod 17 arranged on one side of the turntable 16 and the block 19 arranged in the middle of the outer wall of the limiting rod 18 are inserted along the funnel-shaped protrusion arranged on the inner wall of the limiting tube 10, and then the turntable 16 is rotated to drive the support frame 8 to rotate with the limiting tube 10 arranged on the inner wall of the support plate 9 as the center of the circle, and the exhaust pipe 7 arranged at one end of the support frame 8 together with the fixing frame 5 and the air guide chamber 6 and the plasma fan 4 are moved to the top of one side of the inner wall of the limiting shell 2, so that the input end of the plasma fan 4 is engaged with the air inlet pipe 3 arranged at the top of one side of the inner wall of the limiting shell 2, and the fitting mechanism arranged at the input end of the laser particle detector 11 is used to make It is fitted and fixed to the inner wall of the exhaust pipe 7, and then the plasma fan 4 (here is the prior art) is started. Since the traditional equipment often uses a fan as the traction of the air, the dust in the air is easy to adhere to the surface of the fan blade, and the plasma fan 4 uses high voltage electricity to generate a high voltage electric field between the conductors, thereby releasing a large number of positive and negative ions, and driving the gas to move in one direction. When the air is pulled by the plasma fan 4, since the surface of the conductor continuously releases a large number of positive and negative ions, it is difficult for the dust in the air to adhere to its surface, so that the air passes through the air guide chamber 6, is discharged from one end of the exhaust pipe 7, and is blown into the laser particle detector 11, and the laser particle detector 11 is used to detect the substance content in the air. Detection, when the substances in the air are detected, the turntable 16 is rotated to reset the fixing frame 5 and the air guide chamber 6 and the plasma fan 4, and the multiple devices on the fixing frame 5 at the other end of the support frame 8 are moved to the top of one side of the inner wall of the limiting shell 2, so that it is re-fitted and fixed with the air inlet pipe 3 and the laser particle detector 11, which further solves the problem that during the use of the traditional environmental air quality detection device, the dust particles in the air are easy to adhere to the surface of the pipe and the fan blade, resulting in the subsequent detection of the air in different environments. The dust particles on the surface of the pipe and the fan blade are easy to fall off, resulting in the problem of inaccurate detection results. At this time, the adjustment mechanism is used to make the wheel 32 drive the second push block 34 set on its outer wall to rotate, By setting the second stopper 36 at both ends of the bottom of one side of the outer wall of the air guide bin 6, since the second stopper 36 is supported by the elastic block 37 set on one side of the inner wall of the fixing frame 5, when the second push block 34 is driven by the rotating wheel 32 to rotate, the elastic block 37 is squeezed, and the second stopper 36 supports it, so that the air guide bin 6 falls into the cleaning bin 15, and the cleaning mechanism set on one side of the outer wall of the cleaning bin 15 is started, and the cleaning liquid discharged from the liquid storage bin 13 is used to scrub the inner wall of the air guide bin 6, and then the remaining cleaning liquid is rinsed with clean water discharged from the water storage bin 14, and finally the exhaust bin 12 is used to dry the remaining water stains in the air guide bin 6, so as to prevent dust from adhering to it and affecting the results of subsequent air detection. ;

[0021] The adjustment mechanism includes a turntable 16 rotatably connected to the center of one side of the outer wall of the detection body 1, a fixed rod 17 is fixedly connected to the center of one side of the outer wall of the turntable 16, one end of the fixed rod 17 is fixedly connected to a limit rod 18, a clamping block 19 is fixedly connected to the middle of the outer wall of the limit rod 18, and one end of the outer wall of the limit rod 18 is fixedly connected to a blocking block, and the outer wall of the blocking block is in contact with the limit tube 10, the inner wall of the limit tube 10 is slidably connected to the end of the outer wall of the limit rod 18 away from the blocking block, and the end of the inner wall of the limit tube 10 away from the support plate 9 is fixedly connected to a funnel-shaped protrusion, and the upper and lower ends of the funnel-shaped protrusion are connected to the upper and lower ends of the clamping block 19. The detection body 1 is fixedly connected with a fixed block 27 in the middle of one side of the inner wall, and the inner wall of the fixed block 27 is rotatably connected with a gear 28. A plug hole 29 is provided at the center of one side of the outer wall of the gear 28, and one side of the outer wall of the plug hole 29 is funnel-shaped. The inner wall of the plug hole 29 is slidably connected with the outer wall of the limit rod 18, and the protrusions arranged at the upper and lower ends of the inner wall of the plug hole 29 are engaged with the upper and lower ends of the block 19; when working, a fixed rod 17 is arranged at the center of one side of the outer wall of the turntable 16, and a limit rod 18 is arranged at one end of the fixed rod 17. When the turntable 16 is pushed, the fixed rod 17 moves to one side together with the limit rod 18, so that the limit rod 18 is The block 19 provided at the middle part of the outer wall of the positioning rod 18 is inserted along the funnel-shaped protrusion provided at one end of the inner wall of the limiting tube 10, so that the upper and lower ends of the funnel-shaped protrusion are firmly embedded with the block 19. At the same time, since the diameter of the fixing rod 17 is larger than the limiting rod 18, the fixing rod 17 is used to limit the moving distance of the limiting rod 18. At this time, the turntable 16 is rotated, so that the turntable 16 drives the support frame 8 to rotate, so as to replace the fixing frame 5 provided at one end of the support frame 8 with the fixing frame 5 at the output end of the laser particle detector 11, thereby avoiding the accumulation of dust particles in the air in the pipeline, resulting in the problem of inaccurate detection data. When the air guide in the fixing frame 5 After the replacement of the bin 6 is completed, the turntable 16 is pulled to move the fixing rod 17 together with the limiting rod 18 in the opposite direction, and the block 19 is separated from the funnel-shaped protrusion. A block is provided at one end of the limiting rod 18 to limit the moving distance of the limiting rod 18. A socket 29 is provided at the center of one side of the outer wall of the gear 28, and one side of the outer wall of the socket 29 is funnel-shaped, so that the block 19 is pulled and the block 19 is inserted into the socket 29 and firmly engaged with the protrusions at the upper and lower ends of the socket 29. At this time, the turntable 16 is rotated again, and the gear 28 driven by the turntable 16 is used to rotate the transmission gear plate 30 provided at the bottom of the gear 28.

[0022] A transmission toothed disc 30 is meshed at the bottom of the gear 28, and a rotating shaft 31 is fixedly connected to the middle of the inner wall of the transmission toothed disc 30, and the two ends of the rotating shaft 31 are rotatably connected to one side of the inner wall of the detection body 1 and the middle of one side of the outer wall of the water storage bin 14 respectively, and a rotating wheel 32 is fixedly connected to the two sides of the outer wall of the rotating shaft 31 close to the transmission toothed disc 30, and a first push block 33 is fixedly connected to one end of the outer wall of the rotating wheel 32 close to the transmission toothed disc 30, and a second push block 34 is fixedly connected to the side of the outer wall of the rotating wheel 32 away from the first push block 33, and the angle between the first push block 33 and the second push block 34 is ninety degrees, and the two ends of the top of one side of the outer wall of the air guide bin 6 are fixedly connected to the first stopper 35, and the bottom of one side of the outer wall of the air guide bin 6 is fixedly connected to the first stopper 35. The two ends are fixedly connected with second blocks 36, the bottom of the second block 36 is overlapped with an elastic shift block 37, and one end of the elastic shift block 37 is rotatably connected to one side of the inner wall of the fixed frame 5; when working, a transmission toothed disc 30 is arranged at the bottom of the gear 28, and a rotating shaft 31 is arranged in the middle of the inner wall of the transmission toothed disc 30, and the two ends of the rotating shaft 31 are respectively connected to the inner wall of the detection body 1 and the outer wall of the water storage tank 14, so that when the transmission toothed disc 30 rotates, the outer wall drives the rotating wheels 32 on both sides of the transmission toothed disc 30 to rotate, and a first push block 33 is arranged on one end of the outer wall of the rotating wheel 32 close to the transmission toothed disc 30, and a second push block 34 is arranged on the side of the outer wall of the rotating wheel 32 away from the first push block 33, and the first push block The angle between the second push block 33 and the second push block 34 is ninety degrees. When cleaning the pipeline, some water stains and dust particles are easy to adhere to the surface of the conductor of the plasma fan 4 along the pipeline. In order to avoid the problem of poor contact of the conductor and thus damage when the plasma fan 4 is started to pull the air, a second stopper 36 is provided at both ends of the bottom of one side of the outer wall of the air guide bin 6, and the bottom of the second stopper 36 is supported by an elastic shifting block 37 provided on one side of the inner wall of the fixing frame 5. When the rotating wheel 32 rotates half a circle, the second pusher block 34 pushes the elastic shifting block 37 to cause the elastic shifting block 37 to deviate, so that the air guide bin 6 loses its support and slides from the inner wall of the fixing frame 5 into the cleaning bin 15. When the air guide bin 6 is in the cleaning bin When the cleaning is completed in 15, by setting the first stopper 35 at both ends of the top of one side of the outer wall of the air guide bin 6, when the rotating wheel 32 rotates again, the first push block 33 is used to push the first stopper 35, so that the air guide bin 6 is pushed up from the cleaning bin 15 until the air guide bin 6 rises to the fixed frame 5, at this time, the elastic shift block 37 rebounds and supports the second push block 34, so that the air guide bin 6 is reset in the fixed frame 5, and when it is necessary to clean the air guide bin 6 on the other side, the rotating wheel 32 is rotated in the opposite direction and the above operation is repeated, which further solves the problem that when cleaning the pipeline, the fan blades are often focused on, while the ventilation duct is neglected to be cleaned, which easily causes the inner wall of the pipeline to be covered with dust, thereby affecting the subsequent detection results.

[0023] The cleaning mechanism includes a storage tube 23 fixedly connected to one side of the outer wall of the cleaning bin 15, one side of the outer wall of the storage tube 23 is fixedly connected to an electric rotating telescopic rod 24, the inner wall of the electric rotating telescopic rod 24 is plugged with a drainage hose 25, one end of the drainage hose 25 is fixedly connected to a diverter valve 26, the input end of the diverter valve 26 is respectively fixedly connected to the liquid storage bin 13 and the water storage bin 14, and the top of the liquid storage bin 13 is fixedly connected to one end of the bottom of the water storage bin 14, the output end of the electric rotating telescopic rod 24 is fixedly connected to a soft rubber wiper 38, the soft rubber wiper A flushing pipe 39 is fixedly connected to one side of the outer wall of the cleaning chamber 15, and the inner wall of the flushing pipe 39 is fixedly connected to one end of the drain hose 25. The four corners of the outer wall of the flushing pipe 39 are fixedly connected to elastic polishing plates 40, and the outer wall of the flushing pipe 39 is fixedly connected to a dryer 41 located between the elastic polishing plates 40, and the input end of the dryer 41 is fixedly connected to one side of the outer wall of the exhaust chamber 12; when working, a storage pipe 23 is provided on one side of the outer wall of the cleaning chamber 15, and an electric rotating telescopic rod 24 is provided on one side of the outer wall of the storage pipe 23. When the air guide chamber 6 enters the cleaning chamber 15, the electric The telescopic rod 24 is rotated to make the soft rubber scraper 38 and the flushing pipe 39 arranged at its output end extend into the air guide bin 6. By arranging a drainage hose 25 at one end of the flushing pipe 39, the cleaning liquid in the liquid storage bin 13 enters the drainage hose 25 along the diverter valve 26 and is sprayed out from the flushing pipe 39 to flush the inner wall of the air guide bin 6. The elastic grinding plates 40 arranged at the four corners of the outer wall of the flushing pipe 39 are used to grind and scrape the inner wall of the air guide bin 6. After one reciprocating movement and using the soft rubber scraper 38, the cleaning liquid and foam in the air guide bin 6 are pushed out. At this time, the diverter valve 26 is used to drain the water storage bin 13. The clean water in the bin 14 is sent into the flushing pipe 39 along the drainage hose 25, and the cleaning liquid remaining in the air guide bin 6 is flushed. The cycle is repeated many times and the excess water stains are pushed out by the soft rubber scraper 38. At this time, the exhaust bin 12 is started to send air into the dryer 41 between the elastic polishing plates 40 on the outer wall of the flushing pipe 39 to dry the remaining water stains in the air guide bin 6. This further solves the problem that the remaining water stains in the pipeline are not cleaned during the pipeline cleaning process, resulting in the mixing of water-soluble substances such as methanol with the water stains, thereby causing the detection data to be inaccurate.

To facilitate subsequent brushing, a drainage trough is set at the center of the bottom of the placement bin 42. When the flushing pipe 39 flushes the air guide bin 6, a portion of the waste water generated flows out along the inner wall of the placement bin 42 and flows into the cleaning bin 15 along the drainage trough. Since the holes opened on both sides of the inner wall of the placement bin 42 are smaller than the air guide bin 6, when the electric rotating telescopic rod 24 pushes the flushing pipe 39 and passes through the placement bin 42, the holes are used to scrape off the waste water adsorbed on the surface of the elastic grinding plate 40, and the remaining waste water is discharged from the waste liquid pipe set at the center of the bottom of the cleaning bin 15 along the gap between the placement bin 42 and the cleaning bin 15.

[0025] The laminating mechanism comprises a mounting tube 20 fixedly connected to the output end of the laser particle detector 11, one side of the inner wall of the mounting tube 20 is fixedly connected to an elastic telescopic frame 21, the output end of the elastic telescopic frame 21 is fixedly connected to a collar 22, and the outer wall of the collar 22 has an arc, and the outer wall of the collar 22 overlaps the inner wall of the exhaust pipe 7; when working, by arranging the mounting tube 20 at the output end of the laser particle detector 11, arranging the elastic telescopic frame 21 at one side of the inner wall of the mounting tube 20, and the output end of the elastic telescopic frame 21 is fixedly connected to a collar 22, and the outer wall of the collar 22 has an arc, and the outer wall of the collar 22 overlaps the inner wall of the exhaust pipe 7. A collar 22 is provided at the outlet end. When the support frame 8 drives the exhaust pipe 7 to rotate, since the outer wall of the collar 22 has a certain curvature, when the exhaust pipe 7 contacts the collar 22, it is squeezed by the exhaust pipe 7, so that the collar 22 enters and is embedded in the mounting tube 20. When the exhaust pipe 7 and the mounting tube 20 are at the same level, the elastic telescopic frame 21 is used to push the collar 22 out, and the curved surface of the collar 22 is point-contacted with one end of the exhaust pipe 7, so as to avoid the problem of gaps caused by the fit between the two, resulting in poor air tightness.

[0026] A method for detecting air quality for an environment, the method is as follows: S1: By starting the plasma blower 4, the air is sent into the laser particle detector 11 along the air guide bin 6 for detection, and then the current plasma blower 4 and the air guide bin 6 are moved to the top of the cleaning bin 15 by using the adjustment mechanism, and the air guide bin 6 that has been cleaned at the other end of the support frame 8 is moved to the input end of the laser particle detector 11 for the next batch of detection; S2: By arranging a mounting tube 20 at the output end of the laser particle detector 11, when the collar 22 is squeezed by the exhaust pipe 7, the collar 22 enters the mounting tube 20. When the exhaust pipe 7 and the mounting tube 20 are at the same level, the collar 22 is pushed out by the elastic telescopic frame 21 to make point contact, thereby enhancing the air tightness during air delivery; S3: By setting a second stopper 36 at the bottom of one side of the outer wall of the air guide bin 6, when the second push block 34 pushes the elastic push block 37, the second stopper 36 loses its support and falls into the placement bin 42, so that the air guide bin 6 is separated from the fixing frame 5. At the same time, the vibration generated by the fall is used to shake off the dust in the air guide bin 6, which is convenient for subsequent brushing.

[0027] The working principle of the environmental air quality detection device and its detection method will be described in detail below.

[0028] like Figure 1-13As shown, by moving the detection body 1 to the detection point, pushing the turntable 16 set at the center of one side of the outer wall of the detection body 1, the fixing rod 17 set on one side of the turntable 16, together with the block 19 set in the middle of the outer wall of the limiting rod 18, are inserted along the funnel-shaped protrusion set on the inner wall of the limiting tube 10, and then rotating the turntable 16 to drive the support frame 8 to support the limiting tube 10 set on the inner wall of the support plate 9, and move the exhaust pipe 7 set at one end of the support frame 8 together with the fixing frame 5 and the air guide bin 6 and the plasma fan 4 to the top of one side of the inner wall of the limiting shell 2, so that the input end of the plasma fan 4 is embedded with the air inlet pipe 3 set at the top of one side of the inner wall of the limiting shell 2, and the fitting mechanism set at the input end of the laser particle detector 11 is used to fit and fix it with the inner wall of the exhaust pipe 7. Then, the plasma fan 4 (here is the prior art) is started. Since the traditional equipment often uses a fan as the traction of the air, the dust in the air is easy to adhere to the surface of the fan blades. The plasma fan 4 uses high voltage electricity to generate a high voltage electric field between the conductors, thereby releasing a large number of positive and negative ions, and driving the gas to move in one direction. When the air is pulled by the plasma fan 4, since the surface of the conductor continuously releases a large number of positive and negative ions, it is difficult for the dust in the air to adhere to its surface, so that the air passes through the air guide chamber 6, is discharged from one end of the exhaust pipe 7, and is blown into the laser particle detector 11. The laser particle detector 11 is used to detect the substance content in the air. When the substance in the air is detected, the turntable 16 is rotated. The original fixing frame 5 and the air guide bin 6 are reset with the plasma blower 4, and the multiple devices on the fixing frame 5 at the other end of the support frame 8 are moved to the top of one side of the inner wall of the limiting shell 2, so that they are again fitted and fixed with the air inlet pipe 3 and the laser particle detector 11, which further solves the problem that during the use of the traditional environmental air quality detection device, the dust particles in the air are easily attached to the pipe and the surface of the fan blade, resulting in the subsequent detection of the air in different environments. The dust particles on the surface of the pipe and the fan blade are easy to fall off, resulting in the problem that the detection result is not accurate enough. At this time, the adjustment mechanism is used to set a transmission gear disc 30 at the bottom of the gear 28. Since a rotating shaft 31 is set in the middle of the inner wall of the transmission gear disc 30, and the two ends of the rotating shaft 31 are respectively The inner wall of the main body 1 is connected to the outer wall of the water storage bin 14, so that when the transmission gear disc 30 rotates, the outer wall drives the wheels 32 on both sides of the transmission gear disc 30 to rotate, and a first push block 33 is arranged at one end of the outer wall of the wheel 32 close to the transmission gear disc 30, and a second push block 34 is arranged on the side of the outer wall of the wheel 32 away from the first push block 33, and the angle between the first push block 33 and the second push block 34 is ninety degrees. When cleaning the pipeline, some water stains and dust particles are easy to adhere to the surface of the conductor of the plasma fan 4 along the pipeline. In order to avoid the problem of poor contact of the conductor and thus damage when the plasma fan 4 is started to pull the air, a second stopper 36 is arranged at both ends of the bottom of one side of the outer wall of the air guide bin 6.The bottom of the second stopper 36 is supported by an elastic block 37 provided on one side of the inner wall of the fixing frame 5. When the rotating wheel 32 rotates half a circle, the second push block 34 pushes the elastic block 37, causing the elastic block 37 to deviate, thereby causing the air guide bin 6 to lose support and slide from the inner wall of the fixing frame 5 into the cleaning bin 15. When the air guide bin 6 is cleaned in the cleaning bin 15, the first stopper 35 is provided at both ends of the top of one side of the outer wall of the air guide bin 6. When the rotating wheel 32 rotates again, the first push block 33 is used to push the first stopper 35, thereby pushing the air guide bin 6 from the cleaning bin 15 until the air guide bin 6 rises to the fixing frame 5. At this time, the elastic block 37 rebounds and supports the second push block 34, thereby resetting the air guide bin 6 in the fixing frame 5. This further solves the problem that when the pipeline is cleaned, water stains and some dust particles are easily attached to the surface of the plasma fan 4, resulting in poor contact of the conductor of the plasma fan 4 when it is used again, thereby causing damage.

Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
