The remote detection control module is connected to the formaldehyde data acquisition unit, the data processing unit and the alarm system respectively through a coordinator of a wireless network. The remote detection control module is used to complete the reception and transmission of data and commands between the upper and lower levels. The system adopts optical fiber to transmit light, has a fast transmission speed and strong anti-interference ability, adopts a plurality of formaldehyde data acquisition units with a single-chip microcomputer ADuC834 with high-precision AD to obtain formaldehyde values, cooperates with a remote detection control module with a clock unit, ensures the continuity of formaldehyde monitoring, and realizes the networking of the monitoring system by adopting a data processing unit with an RS485 bus, thereby meeting the requirements of real-time monitoring of formaldehyde concentration. However, in actual use, the system cannot filter dust and impurities in the air, and at the same time, cannot clean the filtering dust and the filtering material of the device, which affects its service life. Summary of the invention

[0007] Specifically, when it is necessary to detect formaldehyde in the air, the staff will turn on the detection device. At this time, the guide piece can introduce external air into the inner cavity of the measuring device for detection. At the same time, the measuring device will first filter the introduced air to prevent dust in the air from entering and interfering with related detection elements. The filtered air will enter the corresponding detection space, and the air will be detected by different detection elements. The detected electrical signal is processed by the electrical signal processing unit and displayed on the display screen for the staff to read. The detected air is discharged to the outside of the detection device through the air duct and the ventilation plate.

[0008] Furthermore, in daily use, the staff can fix the mounting frame in a corresponding position, and then place the detection device on the upper part of the mounting frame through magnetic suction technology. When the detection device needs to be picked up, the staff can directly remove the detection device from the upper part of the mounting frame.

[0009] Preferably, the air guide member includes an air guide tube, which is fixedly mounted on the upper end of the mounting support plate, a transmission rod is provided in the middle of the inner cavity of the air guide tube, a fan blade is provided on the upper portion of the outer surface of the transmission rod, a fan guide fan is provided on the lower portion of the outer surface of the transmission rod, and the middle portion of the outer surface of the transmission rod is connected to the transmission mechanism through a belt.

[0010] Specifically, when it is necessary to detect formaldehyde in the air, the transmission rod rotates under the drive of the transmission mechanism, so that the transmission rod drives fan blade 1 and the air guide fan to rotate at the same time. Fan blade 1 can introduce external air into the inner cavity of the air guide tube, and the air guide fan can introduce the air introduced by fan blade 1 into the inner cavity of the measuring device at a faster speed, so as to cooperate with the measuring device to detect the air.

[0011] Preferably, the measuring device includes a connecting rod, which is fixedly mounted on the middle part of the upper end of the mounting support plate, a collecting mechanism is provided at the lower part of the connecting rod, a protective plate is provided on one side of the inner cavity of the connecting rod, a filter plate is provided in the middle part of the inner cavity of the protective plate, a cleaning mechanism is provided between the protective plate and the filter plate, and a plurality of detection components are provided on the other side of the inner cavity of the connecting rod.

[0012] Specifically, when the guide member introduces the outside air into the inner cavity of the connecting rod, the air will first pass through the protective plate and then be filtered by the filter plate before entering the space where multiple detection components are located, so that the multiple detection components can detect the air. After the detection is completed, the air is exported to the outside of the detection device through the air duct.

[0013] Furthermore, when the detection device is not needed to detect the air, the protective plate can prevent more air from entering the inner cavity of the connecting rod, thereby affecting the service life of the filter plate and the detection component.

[0014] Furthermore, during long-term use of the detection device, a large amount of dust will be adsorbed on the surface of the filter plate, affecting the filtering effect of the filter plate on the air, and a cleaning mechanism will be required to clean the surface of the filter plate. The cleaned dust will be swept into the inner cavity of the collection mechanism by the cleaning mechanism, making it convenient for the staff to clean it.

[0015] Preferably, the protective plate comprises a mounting plate 1, a central array of mounting holes is provided in the mounting plate 1, and baffles are rotatably mounted in the middle of the inner cavities of the plurality of mounting holes.

[0016] Specifically, when the fan guides external air into the inner cavity of the connecting rod, the air with accelerated wind speed can blow up multiple baffles, and then the air enters the inner cavity of the connecting rod through multiple mounting holes. When the detection device is not running, the baffles fit with the corresponding mounting holes under the action of their own gravity, so that external air cannot enter the inner cavity of the connecting rod through the mounting holes. Therefore, the air needs to be introduced into the inner cavity of the connecting rod at a certain speed by the fan guide so that the air can pass through the protective plate and enter the inner cavity of the connecting rod.

[0017] Preferably, the collecting mechanism comprises a second mounting plate, which is fixedly mounted on the lower part of the connecting rod, the inner cavity of the second mounting plate is communicated with the inner cavity of the connecting rod, a collecting box is arranged in the middle part of the inner cavity of the second mounting plate, a telescopic locking mechanism is arranged at one end of the collecting box, a push plate is arranged at one end of the telescopic locking mechanism, and the surface of the push plate extends to the surface of the upper protective cover.

[0018] Preferably, the cleaning mechanism includes a conveying member, which is rotatably mounted on the bottom wall of the inner cavity of the connecting rod, and the conveying member is connected to the transmission mechanism through a belt. A push rod is provided on the outer surface of the conveying member, and a transmission slide is provided on the upper part of the push rod. The inner cavity of the transmission slide is slidably connected to the outer surface of the push rod, and the transmission slide is slidably mounted on the top wall of the inner cavity of the connecting rod. A cleaning member is provided at one end of the transmission slide, and the cleaning member is slidably mounted on the bottom wall of the inner cavity of the connecting rod. A rack is provided on the upper part of the cleaning member, and the rack is fixedly mounted on the inner cavity surface of the connecting rod.

[0019] Specifically, when the transmission mechanism drives the guide member to operate, it will also drive the conveying member to operate, so that the conveying member drives the push rod to move. During the movement of the push rod, the push rod drives the cleaning member to move through the transmission slide. During the movement of the cleaning member, the cleaning member cleans the surface of the filter plate under the action of the rack. The dust cleaned by the cleaning member will be introduced into the inner cavity of the collection box for collection, so that the staff can handle it later.

[0020] Furthermore, after the detection device has been used for a period of time, when the staff needs to deal with the dust collected in the inner cavity of the collection box, the staff can press the push plate to make the push plate drive the telescopic locking mechanism to operate, and then the telescopic locking mechanism can push the push plate outward, so that the staff can pull the collection box out of the inner cavity of the mounting plate two through the push plate.

[0021] Furthermore, the structure of the telescopic locking mechanism is the structure of the telescopic refill on a ballpoint pen, which is a prior art and is not described in detail in this specification.

[0022] Preferably, the cleaning component includes a mounting frame, which is rotatably mounted on the bottom wall of the inner cavity of the connecting rod, the outer surface of the mounting frame is provided with a guide plate, the outer surface of the guide plate is communicated with the inner cavity of the collection box, the inner cavity of the mounting frame is provided with two cleaning blades, and the upper part of the mounting frame is provided with a driven mechanism, which is used to drive the two cleaning blades to rotate.

[0023] Preferably, the spur gear located in the middle of the driven mechanism is meshingly connected with the rack.

[0024] Preferably, the two cleaning blades are adapted for use with the filter plate.

[0025] Specifically, in the process of the transmission mechanism driving the cleaning member to move through the cooperation of the push rod and the transmission slide plate, the driven mechanism is engaged with the rack, so that the driven mechanism can drive the two cleaning blades to rotate. When the two cleaning blades rotate, they can clean the surface of the filter plate, and the cleaned dust is introduced into the inner cavity of the collection box through the guide plate.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. In the present invention, by providing a flow guide and a protective plate, the flow guide can guide the external air into the inner cavity of the protective plate at a certain speed, and the air with a faster flow rate can enter the inner cavity of the connecting rod through the protective plate. When the detection device is not used, the protective plate can prevent more air from entering the inner cavity of the connecting rod, affecting the service life of the filter plate and multiple detection components.

[0028] 2. In the present invention, by providing a cleaning mechanism and a filter plate, the outside air needs to be filtered through the filter plate before being detected by multiple detection components to remove dust and impurities in the air and prevent dust in the air from entering and interfering with related detection elements. During long-term use of the detection device, a large amount of dust will be adsorbed on the surface of the filter plate, affecting the filtering effect of the filter plate on the air. Therefore, a cleaning mechanism is required to clean the surface of the filter plate to prevent the surface of the filter plate from adsorbing a lot of dust and affecting its filtering effect.

DETAILED DESCRIPTION

[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0044] Examples, such as Figure 1 - Figure 4 As shown, this embodiment discloses a formaldehyde detection system for real-time monitoring of formaldehyde concentration with anti-interference, comprising a lower protective cover 1, a detachable mounting frame 2 is arranged at the lower end of the lower protective cover 1, an upper protective cover 3 is arranged at the upper part of the lower protective cover 1, the mounting frame 2 and the upper protective cover 3 together form a protective shell, a display screen 4 and a ventilation plate 5 are arranged on the surface of the upper protective cover 3, and a mounting support plate 7 is arranged in the middle of the space formed by the mounting frame 2 and the upper protective cover 3, and the mounting support plate 7 divides the space formed by the mounting frame 2 and the upper protective cover 3 into upper and lower parts. On the side, a power supply 11 and an electrical signal processing unit 12 are arranged in the space below the mounting support plate 7, a flow guide 6 is arranged on one side of the upper end of the mounting support plate 7, the upper end of the flow guide 6 extends to the outside of the upper protective cover 3, and a transmission mechanism 10 installed on the upper end of the mounting support plate 7 is arranged on one side of the flow guide 6, a measuring device 8 is arranged in the middle of the upper end of the mounting support plate 7, an air guide duct 9 is arranged on one side of the outer surface of the measuring device 8, the inner cavity of the air guide duct 9 is communicated with the ventilation plate 5, and the transmission mechanism 10 is used to transmit kinetic energy to the flow guide 6 and the measuring device 8.

[0045] Specifically, when it is necessary to detect formaldehyde in the air, the staff will turn on the detection device. At this time, the guide member 6 can introduce external air into the inner cavity of the measuring device 8 for detection. At the same time, the measuring device 8 will first filter the introduced air to prevent dust in the air from entering and interfering with related detection elements. The filtered air will enter the corresponding detection space, and the air will be detected by different detection elements. The detected electrical signal is processed by the electrical signal processing unit 12 and displayed on the display screen 4 for the staff to read. The detected air is discharged to the outside of the detection device through the air duct 9 and the ventilation plate 5.

[0046] Furthermore, in daily use, the staff can fix the mounting rack 2 in the corresponding position, and then place the detection device on the upper part of the mounting rack 2 through magnetic suction technology. When the detection device needs to be picked up, the staff can directly remove the detection device from the upper part of the mounting rack 2.

[0047] In order to introduce the external air into the inner cavity of the measuring device 8, the formaldehyde in the air is detected by the measuring device 8, such as Figure 5 and Figure 6 As shown, the air guide member 6 includes an air guide tube 61, which is fixedly mounted on the upper end of the mounting support plate 7. A transmission rod 62 is provided in the middle of the inner cavity of the air guide tube 61, a fan blade 63 is provided on the upper portion of the outer surface of the transmission rod 62, a fan guide fan 64 is provided on the lower portion of the outer surface of the transmission rod 62, and the middle portion of the outer surface of the transmission rod 62 is connected to the transmission mechanism 10 through a belt.

[0048] Specifically, when it is necessary to detect formaldehyde in the air, the transmission rod 62 rotates under the drive of the transmission mechanism 10, so that the transmission rod 62 simultaneously drives the fan blade 63 and the air guide fan 64 to rotate. The fan blade 63 can introduce the external air into the inner cavity of the air guide tube 61, and the air guide fan 64 can introduce the air introduced by the fan blade 63 into the inner cavity of the measuring device 8 at a faster speed, so as to cooperate with the measuring device 8 to detect the air.

[0049] In order to detect the air introduced into the inner cavity of the guide member 6, the introduced air needs to be detected before this, such as Figure 7 - Fig. 9 As shown, the measuring device 8 includes a connecting rod 81, which is fixedly mounted on the middle part of the upper end of the mounting support plate 7, a collecting mechanism 86 is arranged at the lower part of the connecting rod 81, a protective plate 83 is arranged on one side of the inner cavity of the connecting rod 81, a filter plate 84 is arranged in the middle part of the inner cavity of the protective plate 83, a cleaning mechanism 85 is arranged between the protective plate 83 and the filter plate 84, and a plurality of detection components 82 are arranged on the other side of the inner cavity of the connecting rod 81.

[0050] Specifically, when the guide member 6 introduces the outside air into the inner cavity of the connecting rod 81, the air will first pass through the protective plate 83 and then be filtered by the filter plate 84 before entering the space where the multiple detection components 82 are located, so that the multiple detection components 82 detect the air. After the detection is completed, the air is exported to the outside of the detection device through the air duct 9.

[0051] Furthermore, when the detection device is not needed to detect the air, the protective plate 83 can prevent more air from entering the inner cavity of the connecting rod 81 and affecting the service life of the filter plate 84 and the detection component 82.

[0052] Furthermore, during long-term use of the detection device, a large amount of dust will be adsorbed on the surface of the filter plate 84, affecting the filtering effect of the filter plate 84 on the air, and the cleaning mechanism 85 will be required to clean the surface of the filter plate 84. The cleaned dust will be swept into the inner cavity of the collection mechanism 86 by the cleaning mechanism 85, making it convenient for the staff to clean it.

[0053] In order to prevent more outside air from entering the inner cavity of the measuring device 8 when the measuring device 8 is not in operation, so as to prevent more dust in the air from entering the inner cavity of the measuring device 8, as shown in the figure, Fig.10 As shown, the protection plate 83 includes a mounting plate 831, a mounting hole 832 is arranged in an array in the middle of the mounting plate 831, and a baffle 833 is rotatably mounted in the middle of the inner cavity of each of the plurality of mounting holes 832.

[0054] Specifically, after the guide fan 64 introduces external air into the inner cavity of the connecting rod 81, the air with accelerated wind speed can blow up the multiple baffles 833, and then the air enters the inner cavity of the connecting rod 81 through the multiple mounting holes 832. When the detection device is not running, at this time, the baffles 833 fit with the corresponding mounting holes 832 under the action of their own gravity, so that the external air cannot enter the inner cavity of the connecting rod 81 through the mounting holes 832. Therefore, the air needs to be introduced into the inner cavity of the connecting rod 81 at a certain speed through the guide fan 64 so that the air can pass through the protective plate 83 and enter the inner cavity of the connecting rod 81.

[0055] In order to collect the dust swept out by the cleaning mechanism 85 so that the staff can handle it, Fig.11 As shown, the collecting mechanism 86 includes a second mounting plate 861, which is fixedly mounted on the lower portion of the connecting rod 81, the inner cavity of the second mounting plate 861 is communicated with the inner cavity of the connecting rod 81, a collecting box 862 is arranged in the middle of the inner cavity of the second mounting plate 861, a telescopic locking mechanism 863 is arranged at one end of the collecting box 862, a push plate 864 is arranged at one end of the telescopic locking mechanism 863, and the surface of the push plate 864 extends to the surface of the upper protective cover 3.

[0056] In order to clean the surface of the filter plate 84, Fig.11 and Fig.12 As shown, the cleaning mechanism 85 includes a conveying member 851, which is rotatably installed on the bottom wall of the inner cavity of the connecting rod 81, and the conveying member 851 is connected to the transmission mechanism 10 through a belt. A push rod 8511 is arranged on the outer surface of the conveying member 851, and a transmission slide 852 is arranged on the upper part of the push rod 8511. The inner cavity of the transmission slide 852 is slidably connected with the outer surface of the push rod 8511, and the transmission slide 852 is slidably installed on the top wall of the inner cavity of the connecting rod 81. A cleaning member 853 is arranged at one end of the transmission slide 852, and the cleaning member 853 is slidably installed on the bottom wall of the inner cavity of the connecting rod 81. A rack 854 is arranged on the upper part of the cleaning member 853, and the rack 854 is fixedly installed on the inner cavity surface of the connecting rod 81.

[0057] Specifically, when the transmission mechanism 10 drives the guide member 6 to operate, it will also drive the conveying member 851 to operate, so that the conveying member 851 drives the push rod 8511 to move. During the movement of the push rod 8511, the push rod 8511 drives the cleaning member 853 to move through the transmission slide 852. During the movement of the cleaning member 853, the cleaning member 853 cleans the surface of the filter plate 84 under the action of the rack 854. The dust cleaned by the cleaning member 853 will be introduced into the inner cavity of the collection box 862 for collection, so that the staff can deal with it later.

[0058] Furthermore, after the detection device has been used for a period of time, when the staff needs to deal with the dust collected in the inner cavity of the collection box 862, the staff can press the push plate 864 to make the push plate 864 drive the telescopic locking mechanism 863 to operate, and then the telescopic locking mechanism 863 can push the push plate 864 outward, so that the staff can pull the collection box 862 out of the inner cavity of the mounting plate 861 through the push plate 864.

[0059] Furthermore, the structure of the telescopic locking mechanism 863 is the structure of the telescopic refill on a ballpoint pen, which is a prior art and is not described in detail in this specification.

[0060] In order to clean the surface of the filter plate 84, Fig.13 As shown, the cleaning member 853 includes a mounting frame 8531, which is rotatably mounted on the bottom wall of the inner cavity of the connecting rod 81, a guide plate 8533 is provided on the outer surface of the mounting frame 8531, and the outer surface of the guide plate 8533 is communicated with the inner cavity of the collecting box 862, the inner cavity of the mounting frame 8531 is provided with two cleaning blades 8532, and a driven mechanism 8534 is provided on the upper part of the mounting frame 8531, and the driven mechanism 8534 is used to drive the two cleaning blades 8532 to rotate.

[0061] Furthermore, the spur gear located in the middle of the driven mechanism 8534 is meshedly connected with the rack 854 .

[0062] Furthermore, the two cleaning blades 8532 are adapted for use with the filter plate 84 .

[0063] Specifically, in the process of the transmission mechanism 10 driving the cleaning member 853 to move through the cooperation of the push rod 8511 and the transmission slide plate 852, the driven mechanism 8534 is meshed with the rack 854, so that the driven mechanism 8534 can drive the two cleaning blades 8532 to rotate. When the two cleaning blades 8532 rotate, they can clean the surface of the filter plate 84, and the cleaned dust is introduced into the inner cavity of the collection box 862 through the guide plate 8533.

[0064] It should be noted that the specific installation method, circuit arrangement and connection method, and control method of the transmission mechanism 10, power supply 11, electrical signal processing unit 12, and multiple detection components 82 in the above-mentioned embodiment are all conventional designs in the prior art and will not be elaborated in detail in the present invention.
