[0017] The present invention also provides a method for using the indoor environment detection device, which is characterized by comprising the following specific steps:

[0018] S1: The main body of the detection device is placed in the indoor detection area, and the motor is started to drive the limit shaft to rotate. The limit shaft is connected to the first worm through mechanical transmission, so that it drives the first worm to translate and rotate. The first worm drives the first worm wheel to rotate, and the first worm wheel drives the second connecting rod to rotate. The second connecting rod drives the first connecting rod to rotate. The lengths of the first connecting rod and the second connecting rod gradually increase. The first worm wheel and the first worm push the air quality detector forward until the air outlet of the air quality detector moves to the bottom of the air outlet of the detection box.

[0019] S2: While the air quality detector is moving, the synchronous rack group at its bottom is connected through meshing transmission with the transmission gear, driving the transmission gear to rotate. The transmission gear drives the synchronous shaft to rotate, the synchronous shaft drives the second synchronous wheel to rotate, the second synchronous wheel drives the first synchronous wheel to rotate through the synchronous belt, and the first synchronous wheel drives the fan shaft to rotate forward, making the air outlet of the detection box in the air suction state, sucking the air in the area near the air quality detector into the detection box, and filtering it through the filter screen plate;

[0020] S3: While the air quality detector is moving, when the shaft gear at its top moves to one side of the upper rack group, the shaft gear rotates through meshing transmission with the upper rack group, and the shaft gear drives the eccentric dust-proof cover to rotate, making the eccentric dust-proof cover rotate to expose the air outlet of the air quality detector, facilitating the air intake and detection of the air quality detector;

[0021] S4: While the air quality detector is moving, the first connecting rod drives the longitudinal connecting shaft to transmit power, making the second worm on the longitudinal connecting shaft rotate, and then driving the second worm gear connected to it to rotate. The second worm gear drives the transverse connecting shaft to rotate, and the transverse connecting shaft drives another second worm gear connected to it to rotate through another group of second worms. The second worm gear drives the sector gear to rotate through the worm gear shaft. At this time, during the rotation process of the sector gear, it does not contact the meshing gear, and the meshing gear does not rotate;

[0022] S5: Pause the motor, and control the sensor module through the control module built in the air quality detector to detect the carbon dioxide, temperature, humidity and PM2.5 content in the indoor environmental air, and convert the detection results into corresponding signals and send them to the terminal device through the communication module for relevant personnel to view;

[0023] S6: Start the motor, making the automatic sample delivery component work continuously, and the lengths of the first connecting rod and the second connecting rod gradually shorten, retracting the air quality detector to its original position; at the same time, according to the above principle, the eccentric dust-proof cover resets to cover the air outlet and prevent dust from entering the air quality detector;

[0024] S7: At the same time, the second worm gear continuously drives the sector gear to rotate through the worm gear shaft. At this time, during the rotation process of the sector gear, it contacts the meshing gear, and the meshing gear rotates. Then, the meshing gear drives the vertical connecting shaft to rotate, the vertical connecting shaft drives the driven gear to rotate, and the driven gear drives the cleaning brush plate to rotate through mechanical transmission connection with the cleaning tooth ring, and the brush filaments on its surface clean the surface of the filter screen plate;

[0025] S8: Meanwhile, the transmission gear rotates in the reverse direction, causing the fan shaft of the blower to drive the fan blades of the blower to rotate in the reverse direction. At this time, the air outlet of the detection box is in the blowing state, and the dust cleaned from the filter mesh plate is blown outwards to prevent the dust from falling into the detection box, thus completing the air quality detection of the indoor environment.

[0026] Advantages of the present invention:

[0027] 1. For an indoor environment detection device and its usage method proposed in the present invention, the air quality detector is arranged in the detection box, and the automatic sample submission component is used to control the sending out of the detection component for detection and the dust prevention function of taking it in, effectively extending the service life of the device.

[0028] 2. For an indoor environment detection device and its usage method proposed in the present invention, a fan blade is arranged at the air outlet of the detection box. Meanwhile, the forward and reverse rotation of the fan shaft is controlled by the forward and backward translation of the air quality detector, thereby realizing the function of autonomous switching between air suction and exhaust. It can suck the surrounding air into the detection box before the air quality detector detects and filter it through the filter mesh plate, extending the service life of the air quality detector.

[0029] 3. For an indoor environment detection device and its usage method proposed in the present invention, after the detection is completed, the device can also synchronously control the self-cleaning mechanism to clean the surface of the filter mesh plate, and at the same time blow out the dust and debris cleaned through the blowing function to prevent the equipment from getting dusty.

[0056] The present invention also provides a usage method of the above indoor environment detection device, which is characterized in that it includes the following specific steps:

[0057] S1: Place the main body 100 of the detection device in the indoor area to be detected. Start the motor 1031 to drive the limit rotating shaft 1032 to rotate. The limit rotating shaft 1032 drives the first worm 1033 to translate and rotate through mechanical transmission connection with the first worm 1033.

The second connecting rod 1036 drives the first connecting rod 1035 to rotate. The lengths of the first connecting rod 1035 and the second connecting rod 1036 gradually become longer. The first worm gear 1034 and the first worm 1033 push the air quality detector 102 forward until the air inlet of the air quality detector 102 moves directly below the air inlet of the detection box 101;

[0058] S2: While the air quality detector 102 is moving, the synchronous rack group 2046 at its bottom drives the transmission gear 2045 to rotate through meshing transmission connection with the transmission gear 2045. The transmission gear 2045 drives the synchronous shaft 2044 to rotate. The synchronous shaft 2044 drives the second synchronous wheel 2043 to rotate. The second synchronous wheel 2043 drives the first synchronous wheel 2041 to rotate through the synchronous belt 2042. The first synchronous wheel 2041 drives the fan rotating shaft 202 to rotate forward, so that the air inlet of the detection box 101 is in the air suction state, sucking the air in the area near the air quality detector 102 into the detection box 101 and filtering it through the filter plate 201;

[0059] S3: While the air quality detector 102 is moving, when the shaft gear 106 at its top moves to one side of the upper rack group 107, the shaft gear 106 rotates through meshing transmission connection with the upper rack group 107. The shaft gear 106 drives the eccentric dust cover 104 to rotate, so that the eccentric dust cover 104 rotates to expose the air inlet of the air quality detector 102, facilitating the air inlet and detection of the air quality detector 102;

[0060] S4: While the air quality detector 102 is moving, the first connecting rod 1035 drives longitudinal shaft transmission, so that the second worm 3021 on the longitudinal shaft rotates, and then drives the second worm gear 3022 connected to it to rotate. The second worm gear 3022 drives the transverse shaft to rotate. The transverse shaft drives the second worm gear 3022 connected to it to rotate through another group of second worms 3021. The second worm gear 3022 drives the sector gear 3024 to rotate through the worm gear shaft 3023. At this time, during the rotation of the sector gear 3024, it does not contact the meshing gear 3025, and the meshing gear 3025 does not rotate;

[0061] S5: Pause the motor 1031. Through the control module built in the air quality detector 102, control the sensor module to detect the carbon dioxide, temperature and humidity, and PM2.5 content in the indoor environmental air, and convert the detection results into corresponding signals and send them to the terminal device through the communication module for relevant personnel to view;

[0062] S6: Start the motor 1031 to make the automatic sample delivery component 103 work continuously. The lengths of the first connecting rod 1035 and the second connecting rod 1036 gradually shorten to retract the air quality detector 102 to its original position. At the same time, according to the above principle, the eccentric dust cover 104 resets to cover the air outlet and prevent dust from entering the air quality detector 102;

[0063] S7: At the same time, the second worm wheel 3022 continuously drives the sector gear 3024 to rotate through the worm shaft 3023. At this time, during the rotation of the sector gear 3024, it contacts the meshing gear 3025, and the meshing gear 3025 rotates. Then, the vertical coupling is driven through the meshing gear 3025, the vertical coupling drives the driven gear 304 to rotate, and the driven gear 304 drives the cleaning brush plate 301 to rotate through the mechanical transmission connection with the cleaning tooth ring 303, and the surface of the filter mesh plate 201 is cleaned by the brush filaments on its surface;

[0064] S8: At the same time, the transmission gear 2045 rotates in the reverse direction, causing the fan shaft 202 to drive the fan blades 203 to rotate in the reverse direction. At this time, the air outlet of the detection box 101 is in the blowing state, and the dust cleaned from the filter mesh plate 201 is blown outwards to prevent the dust from falling into the detection box 101, completing the air quality detection of the indoor environment.

[0065] The main application environment of this device is indoor environmental areas such as factories with relatively large amounts of dust. And this device can be fixed on a mobile device through relevant fastening components for use, facilitating the switching of the use area; it can also be fixed on a wall-mounted fixture for use, facilitating the continuous detection of the indoor air quality in the same area. The specific installation method can be adjusted according to the requirements of the use scenario.

[0066] It should be noted that: the entire device is controlled by a controller. Since the controller is a common device and belongs to the existing mature technology, the electrical connection relationship and the specific circuit structure are not described in detail here.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
