The radar component 20, the formaldehyde detection component 30, the carbon dioxide sensor 50, the mounting part 40, the PM2.5 sensor 60 and the main control board 70 are integrated on the middle frame 10. That is to say, the radar component 20, the formaldehyde detection component 30, the carbon dioxide sensor 50, the mounting part 40, the PM2.5 sensor 60 and the main control board 70 can be supported by one middle frame 10, meeting the installation requirements of the radar component 20, the formaldehyde detection component 30, the carbon dioxide sensor 50, the mounting part 40, the PM2.5 sensor 60 and the main control board 70, making full use of the space of the middle frame 10, reducing the volume of the middle frame 10, and then reducing the volume of the air detector, reducing the space occupied by the air detector, and further improving the user experience.

[0065] Combine Figure 1 In some embodiments, to facilitate users to intuitively obtain air quality, the air detector further includes: a display unit 100. The display unit 100 is electrically connected to the main control board 70. The main control board 70 sends health data, formaldehyde concentration, temperature and humidity, total volatile organic compound concentration, carbon dioxide concentration, and particulate matter content to the display unit 100, and the display unit 100 displays the health data, formaldehyde concentration, temperature and humidity, total volatile organic compound concentration, carbon dioxide concentration, and particulate matter content.

[0066] Combine Figure 2In some embodiments, in order to facilitate the user to control the start and stop of the air detector, the air detector further includes a switch 110. The switch 110 is electrically connected to the main control board 70 to control the power on and off of the main control board 70.

[0067] In some embodiments, to further facilitate user access to air quality, the air detector further includes a wireless transmission module. The wireless transmission module is located within the middle frame 10 and is electrically connected to the main control board 70. The main control board 70 transmits health data, formaldehyde concentration, temperature and humidity, total volatile organic compound concentration, carbon dioxide concentration, and particulate matter content to the user's mobile phone app via the wireless transmission module, allowing the user and their family to access air quality information via the mobile app.

[0068] In some embodiments, in order to further utilize the space of the middle frame 10, the wireless transmission module can be provided on the main control board 70, thereby reducing the space occupied by the air detector and further improving the user experience.

[0069] Combine Figure 3 and Figure 4 In some embodiments, the cross-section of the middle frame 10 can be rectangular, and the middle frame 10 has a top surface, a bottom surface, a first side surface, a second side surface, a third side surface, and a fourth side surface, wherein the first side surface, the second side surface, the third side surface, and the fourth side surface are sequentially connected.

[0070] Combine Figure 3 、 Figure 4 、 Figure 8 and Figure 9 In some embodiments, in order to fully utilize the space of the middle frame 10, the first mounting position 101 and the sixth mounting position 106 are arranged opposite to each other, and the second mounting position 102, the third mounting position 103, the fourth mounting position 104, and the fifth mounting position 105 are all located between the first mounting position 101 and the sixth mounting position 106. This fully utilizes the space between the first mounting position 101 and the sixth mounting position 106. From the first mounting position 101 to the sixth mounting position 106, the second mounting position 102, the third mounting position 103, the fourth mounting position 104, and the fifth mounting position 105 are staggered. This can reduce the volume of the middle frame 10, compress the radar component 20, the formaldehyde detection component 30, the mounting member 40, the carbon dioxide sensor 50, the PM2.5 sensor 60, and the main control board 70 into one space, reduce the space occupied by the air detector, and further improve the user experience.

[0071] Combine Figure 3 、 Figure 4 、 Figure 8 and Figure 9 In some embodiments, to fully utilize the space of the middle frame 10, the second mounting position 102 and the fourth mounting position 104 are located on the first side of the middle frame 10, that is, the formaldehyde detection assembly 30 and the mounting member 40 are located on the first side of the middle frame 10. The third mounting position 103 and the fifth mounting position 105 are located on the second side of the middle frame 10, that is, the carbon dioxide sensor 50 and the PM2.5 sensor 60 are located on the second side of the middle frame 10, thereby preventing the formaldehyde detection assembly 30 and the mounting member 40 from being located on the same side of the middle frame 10 as the carbon dioxide sensor 50 and the PM2.5 sensor 60. This allows the space on the first side and the second side of the middle frame 10 to be fully utilized, reducing the space occupied by the air detector and further improving the user experience.

[0072] Combine Figure 3 、 Figure 4 、 Figure 8 and Figure 9 In some embodiments, in order to avoid interference between the formaldehyde detection component 30 and the mounting component 40 and the carbon dioxide sensor 50 and the PM2.5 sensor 60, the first side and the second side are arranged opposite to each other, that is, the second mounting position 102 and the fourth mounting position 104 and the third mounting position 103 and the fifth mounting position 105 are opposite to each other, that is, the formaldehyde detection component 30 and the mounting component 40 are opposite to the carbon dioxide sensor 50 and the PM2.5 sensor 60, which facilitates the installation of the formaldehyde detection component 30, the mounting component 40, the carbon dioxide sensor 50 and the PM2.5 sensor 60. At the same time, it is ensured that there is sufficient space on the first side of the middle frame 10 to accommodate the formaldehyde detection component 30 and the mounting component 40, and that there is sufficient space on the second side of the middle frame 10 to accommodate the carbon dioxide sensor 50 and the PM2.5 sensor 60, so that the space of the middle frame 10 can be fully utilized.

[0073] Combine Figure 3 、 Figure 4 、 Figure 8 and Figure 9In some embodiments, in order to make full use of the space of the middle frame 10, the second mounting position 102, the third mounting position 103, the fourth mounting position 104 and the fifth mounting position 105 are all arranged at an angle to the first mounting position 101 and the sixth mounting position 106, so as to meet the installation requirements of the radar component 20, the formaldehyde detection component 30, the carbon dioxide sensor 50, the mounting member 40, the PM2.5 sensor 60 and the main control board 70. At the same time, it also avoids interference between the radar component 20 and the main control board 70 and the formaldehyde detection component 30, the carbon dioxide sensor 50, the mounting member 40 and the PM2.5 sensor 60, thereby facilitating the installation of the radar component 20, the formaldehyde detection component 30, the carbon dioxide sensor 50, the mounting member 40, the PM2.5 sensor 60 and the main control board 70.

[0074] In some embodiments, when the middle frame 10 is rectangular, the angles between the second mounting position 102, the third mounting position 103, the fourth mounting position 104, and the fifth mounting position 105 and the first mounting position 101 and the sixth mounting position 106 can be 90°, and the first mounting position 101 is parallel to the sixth mounting position 106. When the middle frame 10 is placed in the use position, the second mounting position 102, the third mounting position 103, the fourth mounting position 104, and the fifth mounting position 105 can be located on a vertical surface, and the first mounting position 101 and the sixth mounting position 106 can be located on a horizontal surface.

[0075] Combine Figure 3 、 Figure 4 、 Figure 8 and Figure 9 In some embodiments, in order to make full use of the space of the middle frame 10, the middle frame 10 is provided with a accommodating cavity 107, and the third mounting position 103 and the fifth mounting position 105 are arranged in the accommodating cavity 107. It can be understood that the carbon dioxide sensor 50 and the PM2.5 sensor 60 are located in the accommodating cavity 107, and the first mounting position 101, the second mounting position 102, the fourth mounting position 104, and the sixth mounting position 106 are located outside the accommodating cavity. It can be understood that the radar assembly 20, the formaldehyde detection assembly 30, the mounting member 40 and the main control board 70 are located outside the accommodating cavity 107. The carbon dioxide sensor 50 and the PM2.5 sensor 60 are accommodated by the accommodating cavity 107 to facilitate the installation of the carbon dioxide sensor 50 and the PM2.5 sensor 60, thereby fully utilizing the space in the accommodating cavity 107. The radar assembly 20, the formaldehyde detection assembly 30, the mounting member 40 and the main control board 70 are arranged on the outer wall of the middle frame 10, fully utilizing the space outside the accommodating cavity 107, thereby reducing the volume of the air detector, reducing the space occupied by the air detector, and further improving the user experience.

[0076] Combine Figure 3 、 Figure 4 、 Figure 8 and Figure 9In some embodiments, in order to facilitate the installation of the carbon dioxide sensor 50 and the PM2.5 sensor 60, the middle frame 10 is provided with a first opening 108 and a second opening 109 that are connected to the accommodating cavity 107. The first opening 108 is opposite to the third mounting position 103, and the second opening 109 is opposite to the fifth mounting position 105. It can be understood that the carbon dioxide sensor 50 can pass through the first opening 108 to enter the third mounting position 103, so that the carbon dioxide sensor 50 can enter the third mounting position 103, and the PM2.5 sensor 60 can pass through the second opening 109 to enter the fifth mounting position 105, thereby improving assembly efficiency.

[0077] Combine Figure 3 、 Figure 4 、 Figure 8 and Figure 9 In some embodiments, in order to facilitate the arrangement of the carbon dioxide sensor 50 and the PM2.5 sensor 60, the first opening 108 and the first mounting position 101 are located on the same side, and the second opening 109 and the second mounting position 102 are arranged opposite to each other, so as to avoid interference between the installation of the carbon dioxide sensor 50 and the installation of the PM2.5 sensor 60, thereby facilitating the layout of the carbon dioxide sensor 50 and the PM2.5 sensor 60.

[0078] Combine Figure 3 In some embodiments, in order to ensure the accuracy of detection by the PM2.5 sensor 60, the PM2.5 sensor 60 has a PM2.5 detection portion, which is exposed at the second opening 109 to prevent the middle frame 10 from blocking the PM2.5 detection portion, thereby ensuring that the PM2.5 detection portion can fully contact the air and ensure the accuracy of the PM2.5 sensor 60.

[0079] Combine Figure 2 In some embodiments, to ensure the aesthetics of the air detector, the air detector further includes an outer frame 120, and the middle frame 10 is sleeved within the outer frame 120. The first mounting position 101, the second mounting position 102, the fourth mounting position 104, and the sixth mounting position 106 are located between the middle frame 10 and the outer frame 120. The outer frame 120 shields the formaldehyde detection assembly 30, the carbon dioxide sensor 50, the mounting member 40, the PM2.5 sensor 60, and the main control board 70, thereby preventing the formaldehyde detection assembly 30, the carbon dioxide sensor 50, the mounting member 40, the PM2.5 sensor 60, and the main control board 70 from being exposed. While ensuring aesthetics, the formaldehyde detection assembly 30, the carbon dioxide sensor 50, the mounting member 40, the PM2.5 sensor 60, and the main control board 70 can also be protected, ensuring their safety.

[0080] In some embodiments, a first grille and a second grille are provided on the outer frame 120. The first grille is opposite to the second mounting position 102 and the fourth mounting position 104, that is, the first grille is opposite to the formaldehyde detection component 30 and the mounting member 40, to ensure that the formaldehyde detection component 30, the temperature and humidity sensor 80, and the TVOC sensor 90 are fully in contact with the air, thereby ensuring the accuracy of detection by the formaldehyde detection component 30, the temperature and humidity sensor 80, and the TVOC sensor 90. The second grille is opposite to the third mounting position 103 and the fifth mounting position 105, that is, the second grille is opposite to the carbon dioxide sensor 50 and the PM2.5 sensor 60, thereby ensuring that the carbon dioxide sensor 50 and the PM2.5 sensor 60 are fully in contact with the air, thereby ensuring the accuracy of detection by the carbon dioxide sensor 50 and the PM2.5 sensor 60.

[0081] Combine Figure 3 In some embodiments, in order to ensure the accuracy of detection by the carbon dioxide sensor 50, a third opening 1010 is provided on the middle frame 10. The carbon dioxide sensor 50 has a carbon dioxide detection portion, which is exposed at the third opening 1010 to avoid the middle frame 10 blocking the carbon dioxide detection portion, thereby ensuring that the carbon dioxide detection portion can fully contact the air and ensure the accuracy of the carbon dioxide sensor 50.

[0082] Combine Figure 3 ,、 Figure 8 and Figure 9 In some embodiments, to avoid interference with the detection of the carbon dioxide detection unit, the first opening 108 and the third opening 1010 are arranged at an angle. That is, the entry position of the carbon dioxide sensor 50 and the detection position of the carbon dioxide detection unit are at different positions on the middle frame 10. The first opening 108 and the third opening 1010 are independent of each other, which facilitates the installation of the carbon dioxide sensor 50. At the same time, it also ensures that the carbon dioxide detection unit can always be fully in contact with the air, ensuring the accuracy of the carbon dioxide sensor 50. The angle between the first opening 108 and the third opening 1010 can be 90°.

[0083] Combine Figure 4 In some embodiments, in order to ensure the accuracy of detection by the temperature and humidity sensor 80 and the TVOC sensor 90, the temperature and humidity sensor 80 has a temperature and humidity detection part, and the TVOC sensor 90 has a TVOC detection part. The temperature and humidity detection part and the TVOC detection part are away from the middle frame 10 to avoid the middle frame 10 blocking the temperature and humidity detection part and the TVOC detection part, ensuring that the temperature and humidity detection part and the TVOC detection part can fully contact the air, thereby ensuring the accuracy of the temperature and humidity detection part and the TVOC detection part.

[0084] Combine Figure 5In some embodiments, in order to transmit the health data detected by the radar assembly 20 to the main control board 70, the air detector further includes an infrared adapter board 130. The infrared adapter board 130 is located in the first mounting position 101 and is electrically connected to the main control board 70 and the radar assembly 20. The health data detected by the radar assembly 20 is transmitted to the infrared adapter board 130, which then transmits the health data to the main control board 70. At the same time, the infrared adapter board 130 can also be paired with the wired control signal of the wired controller to transmit the wired control signal to the main control board 70.

The first connector 1301 is passed through the fourth opening 1011 and docked with the second connector 201 to achieve the electrical connection between the infrared adapter board 130 and the radar assembly 20, so as to facilitate the transmission of health data detected by the radar assembly 20 to the infrared adapter board 130.

[0086] Combine Figure 7 In some embodiments, due to the high gravity of the radar assembly 20, a first partition 1012 is provided at the first mounting position 101 to prevent the infrared adapter board 130 from bearing the entire weight of the radar assembly 20. Specifically, the middle frame 10 is provided with a first partition 1012, positioned between the infrared adapter board 130 and the radar assembly 20. The first partition 1012 supports the radar assembly 20, so the infrared adapter board 130 only bears a portion of the radar assembly 20's weight. This reduces the load on the infrared adapter board 130, minimizing the possibility of collapse and deformation of the infrared adapter board 130, and ensuring the torsional and bending resistance of the infrared adapter board 130, thereby ensuring its safety. The fourth opening 1011 is provided on the first partition 1012.

[0087] Figure 11 for Figure 7 Top view of the middle frame. Figure 5 、 Figure 9 and Figure 11In some embodiments, since the radar assembly 20 is placed above the infrared adapter board 130, the infrared adapter board 130 will bear part of the weight of the radar assembly 20. In order to ensure the stability of the support of the infrared adapter board 130, a plurality of first support members 1013 are provided in the middle frame 10. The infrared adapter board 130 is provided on the plurality of first support members 1013. The infrared adapter board 130 is supported by the plurality of first support members 1013 to ensure the stability of the infrared adapter board 130 in supporting the radar assembly 20, reduce the possibility of the infrared adapter board 130 collapsing, reduce the possibility of the infrared adapter board 130 being deformed, ensure the torsional and bending resistance of the infrared adapter board 130, and ensure the safety of the infrared adapter board 130.

[0088] In some embodiments, in order to further utilize the space within the middle frame 10, multiple first support members 1013 are provided on the inner circumferential surface of the middle frame 10, that is, multiple first support members 1013 are provided in the accommodating cavity 107. By accommodating multiple first support members 1013 in the accommodating cavity 107, the space within the accommodating cavity 107 is fully utilized, and the volume of the middle frame 10 can be reduced to reduce the volume of the air detector, reduce the space occupied by the air detector, and further improve the user experience.

[0089] In some embodiments, in order to reduce costs, the plurality of first support members 1013 are arranged at intervals, that is, every two adjacent first support members 1013 among the plurality of first support members 1013 are not connected to each other, which can reduce material consumption.

[0090] Combine Figure 5 、 Figure 9 and Figure 11 In some embodiments, to facilitate installation of the infrared adapter board 130, one of the middle frame 10 and the infrared adapter board 130 is provided with at least two first positioning members 1014, and the other is provided with at least two first positioning holes. The first positioning members 1014 are embedded in the corresponding first positioning holes. The number of first positioning members 1014 can be two or more, and the number of first positioning holes can be two or more.

[0091] In some embodiments, when the infrared adapter board 130 is to be installed, the first positioning member 1014 is aligned with the corresponding first positioning hole, and then the first positioning member 1014 is embedded in the corresponding first positioning hole, thereby achieving the installation positioning of the infrared adapter board 130, ensuring the accurate installation position of the infrared adapter board 130, facilitating the installation of the infrared adapter board 130, and improving installation efficiency.

[0092] In some embodiments, the first positioning member 1014 is embedded in the corresponding first positioning hole. After the infrared adapter board 130 is installed in place, the first positioning member 1014 can be used to limit the infrared adapter board 130 to prevent the position of the infrared adapter board 130 from changing, ensure that the position of the infrared adapter board 130 is determined, and ensure the stability of the electrical connection between the infrared adapter board 130 and the radar assembly 20.

[0093] In some embodiments, the middle frame 10 may be provided with at least two first positioning members 1014, the infrared adapter board 130 may be provided with at least two first positioning holes, and the first positioning members 1014 may be embedded in the corresponding first positioning holes. Of course, in other embodiments, the infrared adapter board 130 may be provided with at least two first positioning members 1014, the middle frame 10 may be provided with at least two first positioning holes, and the first positioning members 1014 may be embedded in the corresponding first positioning holes.

[0094] Combine Figure 3 and Figure 5 In some embodiments, to further ensure the stability of the infrared adapter board 130 when mounted on the middle frame 10, a first mounting hole is defined on the infrared adapter board 130, and a second mounting hole is defined on the middle frame 10. The air detector further includes a first connector 140 that extends through the first and second mounting holes. The first connector 140 extends through the first and second mounting holes to connect the infrared adapter board 130 and the middle frame 10, thereby ensuring the stability of the connection between the infrared adapter board 130 and the middle frame 10 and preventing separation of the infrared adapter board 130 and the middle frame 10. Furthermore, the infrared adapter board 130 is positioned securely, ensuring the stability of the electrical connection between the infrared adapter board 130 and the radar assembly 20. The first connector 140 may be a bolt, a screw, a threaded rod, or a connecting pin.

[0095] Combine Figure 3 、 Figure 5 and Figure 9 In some embodiments, to ensure the structural strength of the middle frame 10, at least two reinforcement members 1015 are provided on the inner circumference of the middle frame 10. The at least two reinforcement members 1015 improve the structural strength of the middle frame 10, ensure the stability of the middle frame 10 in supporting the infrared adapter board 130 and the radar assembly 20, and increase the service life of the middle frame 10. The number of reinforcement members 1015 can be two or more.

[0096] In some embodiments, since the infrared adapter board 130 and the radar assembly 20 are located at the first mounting position 101, that is, the first mounting position 101 is the main load-bearing position, therefore, in order to ensure the structural strength of the first mounting position 101, at least two reinforcement members 1015 are provided at the first mounting position 101.

[0097] In some embodiments, in order to facilitate the arrangement of the reinforcement 1015, the inner circumferential surface of the middle frame 10 has a first surface and a second surface connected to the first surface. At least one reinforcement 1015 is provided on the first surface and the second surface, which can fully strengthen the structure of the middle frame 10 and further ensure the structural strength of the middle frame 10.

[0098] In some embodiments, since the reinforcement member 1015 protrudes into the middle frame 10, to facilitate the installation of the infrared adapter board 130, at least two grooves are defined along the edge of the infrared adapter board 130. The reinforcement member 1015 is embedded in the corresponding grooves. The grooves can function as a clearance to allow the reinforcement member 1015 to avoid lifting the infrared adapter board 130, thereby ensuring that the infrared adapter board 130 is properly installed. Furthermore, the grooves can also function as a positioning mechanism. By embedding the reinforcement member 1015 in the corresponding grooves, the infrared adapter board 130 can be positioned accurately, ensuring the installation position of the infrared adapter board 130, facilitating installation of the infrared adapter board 130, and improving installation efficiency. The number of grooves can be two or more.

Figure 15 In some embodiments, to detect human health, the radar assembly 20 includes: a housing 202, a radar module 203, and a radar board 204. The housing 202 is disposed outside the accommodating cavity 107 and is detachably connected to the middle frame 10, with the housing 202 supported by the middle frame 10. It is understood that the housing 202 is disposed on the first partition 1012. The second connector 201 is disposed on the housing 202. The radar module 203 is disposed within the housing 202, which supports and protects the radar module 203. The radar board 204 is disposed within the housing 202 and is electrically connected to the radar module 203. The radar board 204 is supported and protected by the housing 202.

[0100] In some embodiments, the respiratory rate and heart rate of the human body are obtained through the radar module 203, and the respiratory rate and heart rate are sent to the radar board 204. The radar board 204 sends the respiratory rate signal and the heart rate signal to the infrared adapter board 130 through the second connector 201 and the first connector 1301. The infrared adapter board 130 sends the respiratory rate signal and the heart rate signal to the main control board 70. The main control board 70 obtains respiratory rate parameters and heart rate parameters based on the respiratory rate signal and the heart rate signal, and sends the respiratory rate parameters and the heart rate parameters to the display unit 100 for display, so as to know the health status of the user. Since the shell 202 is detachably provided on the middle frame 10, so that the shell 202 and the middle frame 10 are independent of each other, the radar assembly 20 and the middle frame 10 are two independent components. The user can choose whether to install the shell 202 on the middle frame 10 according to the needs of the user. If the user needs the function of detecting human health, the shell 202 is installed on the middle frame 10. If the user does not need the function of detecting human health, the shell 202 is removed from the middle frame 10.

[0101] In some embodiments, human vital parameters are detected by microwaves in the form of pulses. Due to the existence of human vital activities (such as breathing and heartbeat), the callback pulse sequence reflected by the human body changes. In order to ensure the accuracy of the breathing frequency and heartbeat frequency detected by the radar template 203, the radar module 203 can be a millimeter wave radar.

The carbon dioxide sensor 50 is disposed within the second sub-accommodating chamber 1072, and the PM2.5 sensor 60 is disposed within the first sub-accommodating chamber 1071. The second sub-accommodating chamber 1072 accommodates the carbon dioxide sensor 50, while the first sub-accommodating chamber 1071 accommodates the PM2.5 sensor 60. This separates the carbon dioxide sensor 50 from the PM2.5 sensor 60, prevents interference between the carbon dioxide sensor 50 and the PM2.5 sensor 60, and facilitates installation. Furthermore, this fully utilizes the space within the accommodating chamber 107, reducing the volume of the middle frame 10, thereby reducing the volume of the air detector and the space occupied by the air detector, further improving the user experience. The second partition 150 is disposed at the third installation position 103 , that is, the second sub-accommodating cavity 1072 is the third installation position 103 .

The first partition 1501 is connected to the first surface. One end of the second partition 1502 is connected to the first partition 1501, and the other end is connected to the second surface. There is a gap between the first partition 1501 and the second surface, and there is a gap between the second partition 1502 and the first surface, so as to form the second sub-accommodation cavity 1072 to facilitate the accommodation of the carbon dioxide sensor 50 and facilitate the installation of the carbon dioxide sensor 50.

That is to say, when the carbon dioxide sensor 50 is arranged in the second sub-containing cavity 1072, the first partition 1501, the second partition 1502, the first surface and the second surface can be used to limit the carbon dioxide sensor 50 to avoid shaking of the carbon dioxide sensor 50 in the second sub-containing cavity 1072 and change in the position of the carbon dioxide sensor 50, so that the carbon dioxide detection part of the carbon dioxide sensor 50 can always be aligned with the third opening 1010 to ensure that the carbon dioxide detection part can always be in full contact with the air to ensure the accuracy of the detection of the carbon dioxide sensor 50 and ensure the accuracy of the carbon dioxide sensor 50.

[0108] In some embodiments, in order to facilitate the electrical connection between the third connector and the main control board 70, an interface is provided on the main control board 70. When the carbon dioxide sensor 50 is installed in place, the third connector is inserted into the interface, thereby achieving electrical connection between the third connector and the main control board 70 and improving installation efficiency.

[0109] In some embodiments, in order to facilitate preparation and reduce processing costs, the second separator 150 and the middle frame 10 are integrally formed, which also ensures the connection strength between the second separator 150 and the middle frame 10. The second separator 150 and the middle frame 10 can be integrally formed by injection molding.

When the PM2.5 sensor 60 is placed in the second receiving groove 1021, the locking member 170 locks the PM2.5 sensor 60 in the second receiving groove 1021 to ensure the position of the PM2.5 sensor 60 is fixed, preventing the position of the PM2.5 sensor 60 from changing after the PM2.5 sensor 60 is installed, preventing the PM2.5 sensor 60 from falling out of the second receiving groove 1021, and ensuring the stability of the PM2.5 sensor 60 installed in the second receiving groove 1021. The locking member 170 is located in the fifth installation position 105.

[0134] Combine Figure 3In some embodiments, to ensure the stability of the installation of the PM2.5 sensor 60, the locking member 170 includes a second clip 1701. When the PM2.5 sensor 60 is positioned in the second receiving slot 1021, the second clip 1701 is secured to the PM2.5 sensor 60, locking the PM2.5 sensor 60 in the second receiving slot 1021. This ensures the position of the PM2.5 sensor 60 is fixed, prevents the position of the PM2.5 sensor 60 from shifting after installation, prevents the PM2.5 sensor 60 from falling out of the second receiving slot 1021, and ensures the stability of the PM2.5 sensor 60 in the second receiving slot 1021.

[0135] In some embodiments, to facilitate the attachment of the second clip 1701 to the PM2.5 sensor 60, the second clip 1701 is disposed outside the middle frame 10 to avoid interference with the insertion of the PM2.5 sensor 60 into the second receiving groove 1021, thereby ensuring smooth installation of the PM2.5 sensor 60 and facilitating installation of the PM2.5 sensor 60. The second clip 1701 may be disposed at the second opening 109.

[0136] In other embodiments, the locking member 170 may be a stopper. A first hole is defined in the middle frame 10 and communicates with the second receiving slot 1021. A second hole is defined in the PM2.5 sensor 60. When the PM2.5 sensor 60 is positioned in the second receiving slot 1021, the first hole and the second hole are aligned. The stopper, extending through the first hole and connecting the second hole, can also lock the PM2.5 sensor 60, ensuring the position of the PM2.5 sensor 60 is fixed, preventing the PM2.5 sensor 60 from shifting after installation, preventing the PM2.5 sensor 60 from falling out of the second receiving slot 1021, and ensuring the stability of the PM2.5 sensor 60 within the second receiving slot 1021. The stopper may be a latch, a screw, or the like.

[0137] In some embodiments, to facilitate the installation of the PM2.5 sensor 60 , the PM2.5 sensor 60 is located above the main control board 70 , which can fully utilize the space of the middle frame 10 and facilitate electrical connection between the PM2.5 sensor 60 and the main control board 70 .

[0138] In some embodiments, in order to ensure that the position of the PM2.5 sensor 60 is determined, the length of the PM2.5 sensor 60 matches the depth of the second accommodating groove 1021, that is, the distance between the second clip 1701 and the bottom wall of the second accommodating groove 1021 away from the second opening 109 matches the length of the PM2.5 sensor 60. The bottom wall of the second accommodating groove 1021 away from the second opening 109 and the second clip 1701 can be used to limit the PM2.5 sensor 60 to avoid shaking of the PM2.5 sensor 60 in the second accommodating groove 1021 and change in the position of the PM2.5 sensor 60, so that the PM2.5 detection part of the PM2.5 sensor 60 can always be aligned with the second opening 109, ensuring that the PM2.5 detection part can always be in full contact with the air, so as to ensure the accuracy of the detection of the PM2.5 sensor 60 and ensure the accuracy of the PM2.5 sensor 60.

[0139] In some embodiments, in order to ensure that the position of the PM2.5 sensor 60 is determined, the width of the PM2.5 sensor 60 matches the width of the second accommodating groove 1021, and the inner wall of the second accommodating groove 1021 can be used to limit the PM2.5 sensor 60 to avoid shaking of the PM2.5 sensor 60 in the second accommodating groove 1021 and to avoid changes in the position of the PM2.5 sensor 60, so that the PM2.5 detection part of the PM2.5 sensor 60 can always be aligned with the second opening 109, ensuring that the PM2.5 detection part can always be in full contact with the air, so as to ensure the accuracy of the detection of the PM2.5 sensor 60 and ensure the accuracy of the PM2.5 sensor 60.

[0140] In some embodiments, in order to make full use of the space of the middle frame 10, the second accommodating groove 1021 is arranged in the accommodating cavity 107 and opened on the side of the middle frame 10, making full use of the space in the accommodating cavity 107 to reduce the volume of the air detector, reduce the space occupied by the air detector, and further improve the user experience.
