[0026] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Reference Figures 1 to 4 As shown, a preferred embodiment of the air quality monitoring device for tree maintenance in this application includes a housing 1, an air monitoring unit 2, a fan 3, and an air duct 4. The housing 1 is used to connect to the tree and has a cavity 101, an air inlet 102, and an air outlet 103. The air inlet 102 and the air outlet 103 are both connected to the cavity 101. The air monitoring unit 2 and the fan 3 are both connected inside the cavity 101. The fan 3 is used to drive air from outside the housing 1 into the cavity 101. The air duct 4 is connected to the housing 1 and is connected to the air inlet 102. The air duct 4 is used to extend to the canopy of the tree or beyond the canopy.

[0028] In practical applications, the box 1 is connected to the tree trunk, and the air duct 4 extends to the tree canopy or outside the canopy. Based on this, the operation of the fan 3 enables the air in or outside the canopy to form an airflow that enters the cavity 101 through the air duct 4 and the air inlet 102 and is output through the air outlet 103. During this process, the air monitoring unit 2 detects the airflow to obtain the composition information of the air in or outside the canopy. That is, the air quality monitoring device for tree maintenance can monitor the air around the tree canopy and provide data support for the scientific maintenance of trees.

[0029] In this embodiment, the cavity 101 includes a monitoring cavity 1011, an exhaust cavity 1012, and an installation cavity 1013 arranged from top to bottom. The monitoring cavity 1011 communicates with the exhaust cavity 1012 through a ventilation hole 104. An air inlet 102 is located on the top wall of the housing 1 and communicates with the monitoring cavity 1011. An air outlet 103 is located on the side wall of the housing 1 and communicates with the exhaust cavity 1012. The ventilation hole 104 and the air inlet 102 are coaxially arranged. The air monitoring unit 2 includes a sensor assembly 21, a control circuit board 22, and a battery 23. The sensor assembly 21 is connected inside the monitoring cavity 1011, and the control circuit board 22 and the battery 23 are connected to... Inside the mounting cavity 1013, the fan 3, sensor assembly 21, and battery 23 are all electrically connected to the control circuit board 22; the fan 3 is connected inside the monitoring cavity 1011; specifically, since the ventilation hole 104 and the air inlet 102 are coaxially arranged, the airflow entering the cavity 101 from the canopy or outside the canopy is an axial airflow flowing along the axial direction of the air inlet, which facilitates the sensor assembly 21 to monitor the axial airflow. After the airflow enters the exhaust cavity 1012, it is discharged through the air outlet 103; while the control circuit board 22 and battery 23 are located in the mounting cavity 1013, they are less affected by the airflow and operate stably.

[0030] In this embodiment, the control circuit board 22 has a wireless communication module. Furthermore, the sensor assembly 21 includes a laser dust sensor 211 and a VOC sensor 212. The laser dust sensor 211 and the VOC sensor 212 are spaced apart on opposite sides of the ventilation hole 104 in its radial direction. Both the laser dust sensor 211 and the VOC sensor 212 are electrically connected to the control circuit board 22. The laser dust sensor 211 is used to monitor the mass concentration of particulate matter such as PM1.0, PM2.5, and PM10 in real time, while the VOC sensor 212 is used to monitor the content of harmful substances in the airflow. The laser dust sensor 211 and the VOC sensor 212 transmit the monitored information to the control circuit board 22, and the wireless communication module of the control circuit board 22 transmits the information to the background to facilitate the output of scientific maintenance measures. The battery 23 powers the laser dust sensor 211 and the VOC sensor 212.

[0031] For example, the laser dust sensor 211 and VOC sensor 212 can be selected from relevant products of Sifang Optoelectronics Co., Ltd., and can be selected by those skilled in the art based on actual application conditions. This application will not elaborate further on this.

[0032] Furthermore, the air quality monitoring device for tree maintenance may also include a solar panel, which is electrically connected to the control circuit board 22. Thus, the solar panel can convert light energy into electrical energy to charge the battery 23, resulting in good battery life.

[0033] In this embodiment, the fan 3 is connected to the top surface of the monitoring cavity 1011 via a bracket 5. The fan 3 and the air inlet 102 are coaxially arranged. Based on the arrangement of the bracket 5, there is a distance between the fan 3 and the monitoring cavity 1011, which facilitates the introduction of air from the canopy or outside the canopy into the monitoring cavity 1011. It should be noted that the bracket 5 has ventilation holes to ensure that air passes through smoothly. The fan 3 is an axial flow fan 3. The fan 3 is connected to the bracket 5 by screws, and the bracket 5 can also be connected to the top surface of the monitoring cavity 1011 by screws. Of course, the connection between the fan 3 and the bracket 5, and the connection between the bracket 5 and the top surface of the monitoring cavity 1011, can also be achieved by connection methods commonly used in the mechanical field. Moreover, the fan 3 is selected according to actual needs, which will not be elaborated further in this application.

[0034] In this embodiment, the mounting cavity 1013 includes a first chamber 10131 and a second chamber 10132 spaced apart. The control circuit board 22 is connected to the first chamber 10131. The second chamber 10132 has an opening on the outer wall of the housing 1. The battery 23 is detachably connected to the second chamber 10132. The air quality monitoring device for tree maintenance also includes a cover 6, which is detachably connected to the housing 1 and covers the opening. For example, the cover 6 is detachably connected to the housing 1 by screws. Based on the opening and the cover 6, after the cover 6 is removed, the battery 23 can be removed from or installed in the second chamber 10132, which is convenient. It should be noted that the second chamber 10132 is connected to a battery 23 compartment by screws, and the battery 23 is located in the battery 23 compartment.

[0035] It should be noted that the housing 1 also has a channel through which the power supply connection cable passes to ensure the electrical connection between the fan 3, battery 23, laser dust sensor 211, VOC sensor 212 and solar panel and control circuit board 22. This is common knowledge and will not be elaborated on in this application.

[0036] In this embodiment, the air quality monitoring device for tree maintenance also includes a first insect-proof grid 7, which is detachably connected to the outer wall of the housing 1 and covers the air outlet 103. Specifically, the first insect-proof grid 7 can prevent insects from entering the exhaust chamber 1012 through the air outlet 103, thus avoiding insects from affecting the normal operation of the sensor assembly 21. In addition, the first insect-proof grid 7 can be removed for cleaning when needed to avoid clogging the air outlet 103. For example, the outer wall of the housing 1 is provided with a slot, and the first insect-proof grid 7 is detachably inserted into the slot. The structure is simple and easy to install and remove.

[0037] In this embodiment, the air quality monitoring device for tree maintenance also includes a second insect-proof grid 8. The second insect-proof grid 8 is detachably connected to the end of the air duct 4 away from the housing 1 along its length, and the second insect-proof grid covers the opening of the air duct 4. Similarly, the setting of the second insect-proof grid 8 can prevent insects from entering the monitoring chamber 1011 through the air duct 4 and the air inlet 102, and can avoid insects from affecting the normal operation of the sensor assembly 21. In addition, the second insect-proof grid 8 can be removed for cleaning when needed to avoid clogging the air duct 4. For example, the second insect-proof grid 8 is detachably fixed to the air duct 4 by a plug-in cover, wherein the plug-in cover has a clearance hole, and the second insect-proof grid 8 is set in the plug-in cover and covers the clearance hole, ensuring that air can enter the air duct 4 through the clearance hole and the second insect-proof grid 8.

[0038] In this embodiment, the air quality monitoring device for tree maintenance also includes a quick-connect connector 9. The housing 1 and the air duct 4 are connected by the quick-connect connector 9. The quick-connect connector 9 is connected to the housing 1 by a threaded connection and is in communication with the air inlet 102. The quick-connect connector 9 connects the housing 1 and the air duct 4, which has a simple structure and is easy to operate.

[0039] In this embodiment, the air duct 4 includes a main pipe 41, a sleeve 42, and a sealing ring 43. There are multiple main pipes 41, which are coaxially arranged along the length of the air duct 4. Adjacent main pipes 41 are detachably connected by a sleeve 42. One of the two adjacent main pipes 41 is a first main pipe and the other is a second main pipe. The sleeve 42 is provided with a sealing ring 43, which is coaxially arranged with the sleeve 42. The first main pipe is fixedly inserted into one end of the sleeve 42 and abuts against the sealing ring 43. The second main pipe is fixedly inserted into the other end of the sleeve 42 and abuts against the sealing ring 43. The air duct 4 with this structure has sufficient sealing performance to prevent leakage during air transportation and can be disassembled into multiple main pipes 41 when not in use, making it easy to store.

[0040] It should be noted that each of the above-mentioned sleeves is provided with a sealing ring 43, and the number of main tubes 41 can be three, four or more. Correspondingly, the number of sleeves and sealing rings 43 is also set according to the number of main tubes 41, which is set according to the height of the trees whose air needs to be monitored. This application does not limit this.

[0041] In practical applications, the air duct 4 can be placed among the branches in the canopy to maintain stability, which will not be elaborated upon in this application.

[0042] In this application, the outer wall of the box body 1 is connected to a mounting ear 10, which has a mounting through hole 10A. The mounting ear 10 is connected to the box body 1 by integral molding. The air quality monitoring device for tree maintenance also includes a strap 11, which passes through the mounting through hole 10A. The strap 11 is used to connect to the tree. In practical applications, the box body 1 is fixed to the trunk of the tree by binding. Its structure is simple, easy to operate and will not damage the bark of the tree.

[0043] In this embodiment, the housing 1 includes two sub-housing units, which are connected by screws or snap-fit ​​to form the housing 1, so as to facilitate the installation of the air monitoring unit 2 and the fan 3.
