[0056] In order to verify the technical effect that the aerosol-generating device of the present application realizes more timely liquid substrate delivery compared with the existing aerosol-generating device, the pressure in the first liquid storage cavity of the aerosol-generating device of the present application and the existing aerosol-generating device is tested. Among them, the structure of the aerosol-generating device provided by the present application and the existing aerosol-generating device is basically the same, the difference is only that in the aerosol-generating device provided by the present application, the side wall of the liquid guide column 121 is provided with a first liquid guide hole 1211, and a second liquid guide hole 1212 is also provided at the bottom; while in the existing aerosol-generating device, only the first liquid guide hole 1211 is provided in the side wall of the liquid guide column 121.

[0057] The test conditions of the above two aerosol-generating devices are as follows: multiple cycles of suction are provided at a certain frequency, the suction flow rate is 27.5 ml / s, and the cycle is performed according to the rhythm of stopping for 15 s after 2 s of suction. In the process of cyclic suction, the liquid substrate is consumed, and a pressure value in the first liquid storage cavity is tested every 1 s, and the test results are shown in Figure 6 and Figure 7 Figure 6 is a pressure test result graph of the first liquid storage cavity of the existing aerosol-generating device, Figure 7 is a pressure test result graph of the first liquid storage cavity of the aerosol-generating device of the present application. Among them, Figure 6 and Figure 7 The abscissa of Figure 6 and Figure 7 The ordinate represents the pressure value, the test frequency 1 Hz represents that a pressure value is tested every second, and the peak value of the pressure value represents that the negative pressure in the first liquid storage cavity changes suddenly, that is, the negative pressure value in the first liquid storage cavity recovers from a smaller value to a larger value, so as to represent that a gas bubble enters the first liquid storage cavity and thus relieves the negative pressure.

[0058] from Figure 6 and Figure 7 ​It can be seen that, in the existing aerosol generating device, the interval length of two adjacent negative pressure peaks is greater than the interval length of two adjacent negative pressure peaks in the aerosol generating device of the present application, indicating that as the liquid substrate is consumed, the negative pressure value in the first liquid storage cavity will gradually decrease to limit the outflow of the liquid substrate, while in the aerosol generating device of the present application, the time for relieving, restoring or eliminating the negative pressure in the first liquid storage cavity during the puffing process is shorter. Therefore, compared with the existing aerosol generating device, the aerosol generating device of the present application has more pressure peaks in the same time period, indicating that more air bubbles can enter the first liquid storage cavity in the same time period, and the liquid substrate in the liquid supply mechanism of the present application can be more smoothly provided to the atomization mechanism.

[0059] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but the present application can be implemented in many different forms and is not limited to the embodiments described in the specification. These embodiments are not additional limitations on the content of the present application, and the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. Furthermore, the above technical features continue to be combined with each other to form various embodiments not listed above, which are considered to be within the scope of the present application. Furthermore, for those skilled in the art, the above description can be improved or changed, and all these improvements and changes should be within the scope of the appended claims of the present application.
