[0033] The technical solutions of the present application will be described clearly and completely in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0034] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation of the present application. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] TPM (Total Particulate Matter) refers to the total amount of all suspended particulate matters in the air, including solid particles (such as dust, soot) and liquid particles (such as aerosol, fog droplets), and the particle size range covers various types from ultrafine particulate matter (<0.1 μm) to PM10 (<10 μm) and the like.

[0037] The aerosol generating device needs to be tested for TPM value. When a large number of products need to be tested for TPM value, the products are first weighed and the initial weight is recorded, then the products are sucked, the weight after suction is recorded, and the TPM value of the products is calculated by weight method. In this process, manual weighing and calculation are required, and since there are many manual interventions, it is easy to cause deviation in the measurement results. If a large number of tests are performed, the deviation in this process will become larger. Therefore, the present application provides an aerosol test device to solve the above technical problems.

[0038] As shown in Figure 1 Figure 4 The aerosol test device provided by the embodiments of the present application comprises:

[0039] A suction assembly 1 having a suction port 2 for sucking the aerosol generated by the aerosol generating device to be tested;

[0040] An adjustable clamp 4 for clamping the aerosol generating device so that the aerosol generating device is connected to the suction port 2;

[0041] A measurement assembly 3, wherein the adjustable clamp 4 is arranged on the measurement assembly 3, and the measurement assembly 3 is used to measure the weight change of the aerosol generating device to obtain test data for calculating the total particulate matter concentration of the aerosol.

[0042] ​The suction assembly 1 has a suction port 2 for suctioning the aerosol generated by the aerosol generating device to be tested, and the measurement assembly 3 is located on one side of the suction assembly 1, and the measurement assembly 3 has an adjustable clamp 4 for clamping the aerosol generating device. The aerosol generating device can be clamped by the adjustable clamp 4, and the clamped aerosol generating device is inserted into the suction port 2 of the suction assembly 1 to test the TPM value of the to-be-tested object.

[0043] It should be noted that the measurement assembly 3 is signal connected with the suction assembly 1. This structure design can automatically record and weigh the suction assembly 1, so as to effectively calculate the TPM value of the aerosol generating device, so as to achieve the effect of accurate measurement.

[0044] The application can effectively provide the accuracy of the measured value during testing. The application is described by way of example as follows: first, the technical personnel fix the aerosol generating device on the adjustable clamp 4, and insert the fixed aerosol generating device into the suction port 2, then the device can test the TPM value of the to-be-tested object. After the test starts, the measurement assembly 3 weighs the initial weight of the to-be-tested object, and then sets the suction assembly 1 to suction the aerosol generating device 50 times. After suctioning 50 times, the measurement assembly 3 immediately measures the weight of the measurement assembly 3 after suctioning 50 times. Finally, the measurement assembly 3 and the suction assembly 1 transmit data, and the suction assembly 1 can automatically record the weight and calculate the TPM value. In this process, the steps of manual calculation and the process of manual weighing are omitted, which effectively reduces the generation of errors, thereby greatly improving the accuracy of the measured data information of the device.

[0045] In the application, the technical personnel only need to fix the aerosol generating device on the adjustable clamp 4, and insert the fixed aerosol generating device into the suction port 2 of the suction assembly 1. When the suction assembly 1 works to suction the aerosol generating device, the measurement assembly 3 arranged below the adjustable clamp 4 can measure and record the weight change of the aerosol generating device in real time. By calculating the weight change value of the aerosol generating device before and after suctioning, the test data of the mass of the output aerosol is indirectly obtained, and the total particulate matter concentration is calculated based on the test data of the mass of the aerosol. In this process, errors generated in the process of manual weighing (such as the weight of the to-be-tested object after suctioning 50 times, but since manual weighing needs a certain time, and the to-be-tested object is not directly weighed after suctioning 50 times, so the weighed weight is not the actual weight of the to-be-tested object after suctioning 50 times) and errors generated in the process of manual calculation (such as a large number of tests, since the human energy is limited, so errors are inevitable in the calculation process) can be effectively avoided. Not only the detection efficiency is improved, but also the calculation accuracy is improved.

[0046] It should be noted that a stable environment needs to be maintained during the test, that is, the test environment is controlled at constant temperature and humidity conditions to avoid the influence of environmental factors on the TPM value, for example, the temperature is controlled at 22±2℃, and the relative humidity is controlled at 60±5%. And the environment needs to be detected during the test, such as using a thermometer to monitor the environmental conditions in real time to ensure that the environment is stable during the test. In addition, external interference needs to be avoided during the test, that is, during the test, the influence of external air flow on the smoke collection of the test object can be avoided, and a closed test cavity or a ventilation system can be used to control air flow. Among them, the ventilation system is, for example, an existing air conditioner, exhaust fan, etc.
