[0020] Example

[0021] A portable automobile glass film volatile organic compound detector includes a temperature-controlled test box, an air sampling pump 14, and a detection system 15. The temperature-controlled test box, the air sampling pump 14, and the detection system 15 are all detachably connected, and are small in size and easy to carry. The temperature-controlled test box includes a box cover 9 and a box body 10. The box cover 9 is sealed and connected to the box body 10, and a timer is provided on the outside of the box cover 9. The temperature-controlled test box can control and adjust its internal temperature. The temperature-controlled test box can accurately control the temperature within the range of room temperature to 100°C, and is well sealed to ensure no air leakage. The box cover 9 of the temperature-controlled test box can be opened to facilitate the placement of samples, and to ensure that the sealing of the temperature-controlled test box is not affected.

[0022] The side of the temperature-controlled experimental box is provided with a cleaning air inlet pipe 12 and a sampling air inlet pipe 11 which are connected to the inside of the temperature-controlled experimental box. The air sampling port of the air sampling pump 14 is connected to the sampling air inlet pipe 11 through the sampling pipe. The air sampling pump 14 delivers the collected gas to the detection system 15 for detection. The temperature-controlled experimental box pre-treats the sample at a certain temperature. The experimental box can set the experimental temperature, and the experimental time is set by the timer. When the experimental timer ends, the sampling air inlet pipe 11 automatically opens, and the sampling air inlet pipe 11 is connected to the air sampling pump 14 through the sampling pipe to start sampling. The air sampling pump 14 has the function of presetting the sampling flow rate and sampling time. When the sampling air inlet hole of the temperature-controlled experimental box is connected to the air sampling pump 14, the air sampling pump 14 can simultaneously start the air sampling function to collect samples, and then send the collected gas to the detection system 15 for analysis and detection. The automatic opening and closing method of the sampling air inlet pipe 11 and the design of the control structure and the preset sampling function of the air sampling pump 14 belong to the prior art and will not be repeated here.

[0023] The detection system 15 includes a detection module, an analysis module, and a data processing module. The detection module is provided with a plurality of gas sensors. The detection system 15 has gas detection, analysis, and data calculation functions. The detection module is provided with a plurality of gas sensors. The gas entering the detection system 15 is analyzed and detected by preset sensors, such as formaldehyde sensors, benzene sensors, toluene sensors, etc., and the detection data is transmitted to the calculation module, and finally the release amount of volatile organic compounds in the glass film is calculated.

[0024] A sample holder is provided inside the temperature-controlled experimental box. The sample holder can vertically place at least two 30cm×30cm glass film samples. The sample holder includes a holder slot 1, multiple partitions 2, and a sample clamp 4. The multiple partitions 2 divide the holder slot 1 into multiple uniform sample chambers 3. Sample clamps 4 are provided at the top of both ends of one side wall of the sample chamber 3. A glass film sample is placed in each sample chamber 3. The glass film sample is in a square shape. The sample clamp 4 at the top of the side wall of the sample chamber 3 clamps the two corners of the glass film sample to keep the glass film sample vertically placed in the sample chamber 3, ensuring the placement of the sample and improving the accuracy of the test results. Multiple sample chambers 3 can hold multiple samples at the same time.

[0025] The support groove 1 is concave, and the side wall and the partition 2 of the support groove 1 are hollowed out (not shown in the figure), and the two ends of the support groove 1 are open. The hollowing and opening design facilitates the release of volatile organic matter from the glass membrane sample and facilitates the collection by the gas sampling pump 14.

[0026] The sample holder 4 is plugged into the side wall of the sample chamber 3. A plug is provided on the side of the sample holder 4 close to the side wall of the sample chamber 3, and the top of the plug is spherical. A socket 7 is provided at the position of the side wall of the sample chamber 3 corresponding to the sample holder 4. The socket 7 includes two symmetrically arranged spring pieces 5, one end of which is connected to the inner wall of the sample chamber 3, and a ball groove 6 corresponding to the top of the plug is provided on the opposite sides of the two spring pieces 5, and the opening width of the socket 7 is smaller than the diameter of the plug. The material of the spring piece 5 can produce a certain degree of elastic deformation. When the plug is inserted into the socket 7, since the opening width of the socket 7 is smaller than the diameter of the ball part of the plug, when the plug is inserted into the socket 7, the spring pieces 5 on both sides of the socket 7 will undergo elastic deformation. When the plug is inserted into the socket 7, the ball part of the plug is located in the ball groove 6 on the side of the spring piece 5, and at the same time, the spring pieces 5 on both sides also eliminate the elastic deformation and return to the original state. The cooperation between the plug and the socket 7 facilitates the installation of the sample holder 4. The sample clamp 4 can be first clamped at two corners of the sample and then placed in the sample chamber 3 to install the sample clamp 4. Alternatively, the sample clamp 4 can be first installed in the sample chamber 3 and then the sample can be clamped.

[0027] When in use, the box cover 9 and the box body 10 of the temperature-controlled experimental box are opened, and the cleaning air inlet pipe 12 is connected through the air sampling pump 14 to clean the air inside the temperature-controlled experimental box to prevent residual volatile organic compounds from affecting the test results. After cleaning, the glass membrane sample to be tested is placed in the sample chamber 3, the box body 10 and the box cover 9 are closed, the experimental temperature is set through the temperature-controlled experimental box, the experimental time is set through the timer, and the glass membrane sample is pre-treated. When the timing ends, the sample pre-treatment ends. At this time, the collection air inlet pipe of the temperature-controlled experimental box is connected with the air sampling pump 14 through the air sampling pipe 13. The air sampling pump 14 has preset the sampling flow rate and sampling time. The air sampling pump 14 collects the volatile organic compounds generated in the temperature-controlled experimental box and transports them to the detection system 15. The detection system 15 analyzes and detects the gas entering the detection system 15 through the sensor, and transmits the detection data to the calculation module, and finally calculates the release amount of volatile organic compounds in the glass membrane.

[0028] Therefore, the utility model adopts the above-mentioned portable automobile glass film volatile organic compound detector for the detection of automobile glass film volatile organic compounds. It is small in size, easy to carry, simple to operate, can ensure the placement of glass film samples, and improve the accuracy of detection results.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
