Referring to fig. 1, fig. 1 is a schematic structural diagram of a heating tube L of an electronic cigarette.
As shown in fig. 1, the heating tube L includes a main body portion L1 and a bent portion L2, the main body portion L1 and the bent portion L2 are both cylindrical, and the main body portion L1 is communicated with the bent portion L2 to transmit the mist formed by atomizing the raw material. Wherein, heating pipe L still includes temperature control line L3, and temperature control line L3 is used for testing heating pipe L's temperature to the control of heating pipe L temperature.
The application provides an air tightness test fixture 10 for testing the air tightness of a heating pipe L of an electronic cigarette. Referring to fig. 2, fig. 2 is a schematic structural diagram of an embodiment of the hermeticity test fixture 10 provided in the present application.
As shown in fig. 2, the airtightness testing jig 10 includes a fixing assembly 11, a communicating member 12, a sealing member 13, and a driving assembly.
Specifically, the fixing component 11 is used for fixing the heating pipe L to prevent the heating pipe L from moving when performing the air tightness test, so as to prevent the accuracy of the air tightness test from being affected. One end of the communication member 12 communicates with an air pressure detecting device (not shown), and the other end of the communication member 12 is adapted to communicate with the opening Q1 of the main body portion L1. The sealing member 13 is used to seal the opening Q2 of the bent portion L2 to prevent air leakage from the opening Q2 of the bent portion L2 during air-tightness detection.
More specifically, the fixing component 11 can fix the heating pipe L by clamping and abutting against the heating pipe L. One end and the other end of the communicating member 12 are opposite ends of the communicating member 12, the communicating member 12 has a closed air passage extending from one end to the other end of the communicating member 12, and the main body portion L1 is communicated with the air pressure detecting device through the closed air passage.
Alternatively, the communicating member 12 may be an air pipe joint, one end of which is communicated with an air pipe of the air pressure detecting device, and one end of which is used for being communicated with the opening Q1 of the main body portion L1.
Specifically, the sealing member 13 may be a flexible sealing gasket capable of completely covering the opening Q2 of the bent portion L2 to prevent gas from leaking from the opening Q2 of the bent portion L2 during the airtightness detection.
Specifically, the air pressure detection device may include a gas pumping device or a gas extraction device, and the air pressure in the heating pipe L is increased by the gas pumping device, or the air pressure in the heating pipe L is decreased by the gas extraction device, and the tightness of the heating pipe L is determined by detecting the maintenance performance of the air pressure in the heating pipe L.
Specifically, the driving assembly is used for driving the other end of the communicating piece 12 to communicate with the opening Q1 of the main body portion L1 and driving the sealing piece 13 to seal the opening Q2 of the bent portion L2.
More specifically, the driving assembly may drive the entirety of the communicating member 12 or only the other end of the communicating member 12 such that the other end of the communicating member 12 is in contact with and communicates with the opening Q1 of the main body portion L1. Wherein, when the driving component drives only the other end of the communicating member 12, the other end of the communicating member 12 is a telescopic end.
Alternatively, the drive assembly may comprise a plurality of drive members which drive the communication member 12 and the sealing member 13 respectively.
When the airtightness of the heating tube L is tested, first, the driving assembly drives the communication piece 12 such that the other end of the communication piece 12 communicates with the opening Q1 of the main body portion L1, and drives the sealing member 13 to seal the opening Q2 of the bent portion L2. Then, the air pressure detection device changes the air pressure in the heating pipe L by filling or extracting the air, and further determines the air tightness of the heating pipe L by detecting the maintenance performance of the air pressure. If the gas pressure remains constant or changes only slightly over a certain period of time, the gas tightness of the heating tube L is indicated to be good. If the air pressure changes greatly within a certain time, it indicates that the airtightness of the heating pipe L is not good.
Therefore, in the above embodiment, the airtightness test fixture 10 provided by the present application can provide good sealing effects for the opening Q1 of the main body portion L1 and the opening Q2 of the bent portion L2 of the heating tube through the communicating piece 12 and the sealing piece 13, respectively, thereby improving the accuracy of the airtightness test on the heating tube L. Moreover, the driving assembly can improve the automation degree of the air tightness testing process, and further improve the testing efficiency.
