BEST MODE FOR CARRYING OUT THE INVENTION

[0035] In order to have a clearer understanding of the technical features, objects and effects of the present invention, a detailed description will be made with reference to the accompanying drawings. A specific embodiment of the invention will be apparent.

[0036] As shown in FIG. 1, the electronic cigarette 100 of the first embodiment of the present invention includes a power supply device 1, a heat generating component 2, and a control device 3. The control device 3 is electrically connected to the power supply device 1, the heat generating component 2, and the power supply device. 1 supplies electric power to the control device 3 and the heat generating element 2.

[0037] The main components of the smoky oil are glycerol and propylene glycol, and the boiling points of the two are different, and the specific heat capacity is different. For the smoky oil of different composition, the ratio of glycerol to propylene glycol is generally different, so When the same power is used to heat the smoke oil, the temperature profile of the heat generating element 2 may vary depending on the composition of the heated smoke oil.

[0038] As shown in FIG. 1, the temperature change curve of each of the smoke oil heating heat generating elements 2 includes a temperature rapid rising section A and a temperature stable section B. In the rapid temperature rising section A, the temperature rapidly climbs, and In the temperature stabilization section B, since a large amount of smoke oil is atomized to absorb heat, the temperature of the heat generating component 2 changes slowly. Different proportions of smoke oil, because the ratio of glycerol and propylene glycol in the mixture is often different, resulting in a certain temperature difference in the temperature stability section B, therefore, it is very necessary to control the atomization temperature range of the smoke oil, fog Higher temperatures result in wasted energy, low energy utilization, and lower atomization temperatures, which can result in insufficient amounts of smoke. Therefore, it is necessary for the user to pump different types of smog, and to select a suitable atomization temperature range depending on the composition of the smoky oil.

As shown in FIG. 2, the control device 3 includes a temperature detecting module 31 and a control module 32. The temperature detecting module 31 is for detecting temperature change data of the heat generating element 2. The control module 32 can obtain the temperature change curve of the heat generating component 2 according to the data detected by the temperature detecting module 31, and then select a pre-controlled temperature range according to the temperature change curve, and control the temperature control of the heat generating component 2 in the subsequent electronic cigarette suction 吋Within the pre-controlled temperature range selected above.

[0040] The pre-controlled temperature range needs to be in the temperature stable section B of the temperature change curve, and the temperature change of the heating is not too large.

[0041] The method of controlling the heat generating component 2 within a temperature range can be referred to the Chinese invention patent application CN2014102891 54.7. The selected pre-control temperature range needs to be located in the temperature stability section B of the temperature change curve. The specific selection method of the pre-control temperature range includes the following cases:

[0042] 1. The temperature range in which the electronic cigarette 100 is located after a certain period of time. Considering that the electronic cigarette is sucked by 00, the temperature of the heat generating component 2 generally reaches the temperature stable section B after 1.5 seconds, and therefore, E-cigarette 100 is used to select between the snoring, for example, the temperature range in which the e-cigarette 100 is switched from 1.5 seconds to 2.5 seconds after the snoring is used as the pre-controlled temperature range. It can be understood that, for different e-cigarettes 100, there is a slight difference between the diurnal peaks reached by the temperature stabilization section B;

[0043] 2. The temperature rise rate of the heat generating element 2 is smaller than the temperature range of the specific speed. Considering that after the heat generating component 2 reaches the temperature stable section B, the temperature rising speed is generally less than 5 degrees/200 milliseconds. Therefore, the pre-control temperature range can be selected according to the temperature change speed of the heat generating component 2, for example, the temperature rising speed is generally selected. A temperature range of less than 5 degrees / 20 0 milliseconds is used as the pre-controlled temperature range. It can be understood that, for different electronic cigarettes 100, the speed of temperature rise may be slightly different after reaching the temperature stable section B due to the difference in power thereof;

[0044] 3. If the electronic cigarette 100 has no defects in the liquid supply, considering that the heating element 2 is in a suction process (generally lasting 3 to 5 seconds), the highest temperature value is also in the temperature stabilization section B, therefore, The highest temperature value of the heating element 2 is selected to select the pre-controlled temperature range, and the temperature range within a specific range below the highest temperature value of the heating element 2 is selected, for example, the pre-controlled temperature range is selected to be within 20 degrees of the highest temperature value.

In the present embodiment, the heat generating element 2 is made of a material having a temperature coefficient of resistance characteristic, and the control device 3 deviates from the temperature of the heat generating member 2 by the resistance of the heat generating member 2. Further, the material of the heat generating component 2 is made of one or more of platinum, copper, nickel, titanium, iron, ceramic-based PTC material, and polymer-based PTC material, and the resistance value thereof is related to the temperature of the heat generating component 2. Increase and increase. Correspondingly, the temperature detecting module 31 includes a voltage detecting element 33 and a current detecting element 34 for detecting the voltage and current of the heat generating component 2, respectively, and calculating the resistance of the heat generating component 2 to obtain a temperature.

As shown in FIG. 3, in the second embodiment of the present invention, the heat generating element 2 may also be a conventional heat generating material. The main difference between the electronic cigarette 200 in the second embodiment of the present invention and the electronic cigarette 100 in the first embodiment of the present invention includes: the heat generating member 2 is made of a material having a non-resistance temperature coefficient characteristic; and the temperature detecting module 31 includes a temperature sensor 36. . The temperature sensor 36 is for detecting a temperature change of the heat generating element 2.

[0047] The control device 3 may further include a storage module 35, the storage module 35 may store the temperature change curve of the heat generating component 2, and the temperature change curve stored in the storage module 35 may be in the power supply device 1 and the heating element 2 Broken mechanical connection 吋 clear. Here, the broken mechanical connection is exemplified as follows: The electronic cigarette 100 includes a battery rod as the power supply device 1, and an atomizing assembly having the heat generating component 2, and when the atomizing assembly is assembled to the battery rod, the mechanical connection is formed. When the atomizing assembly is detached from the battery rod, it is called a mechanical connection. [0048] As shown in FIG. 4, the heating atomization control method of the electronic cigarette includes the following steps:

[0049] A, the electronic cigarette is obtained, and the temperature change curve of the heat generating component 2 is obtained;

[0050] Specifically, when the electronic cigarette is activated, the electronic cigarette first supplies power to the heat generating component 2 at a predetermined power or a predetermined voltage, and acquires a temperature variation curve of the heat generating component 2. The obtained temperature change curve of the heat generating element 2 can be stored in the storage module 35.

[0051] B, selecting a corresponding pre-control temperature range according to a temperature change curve of the heat generating component 2;

[0052] C. The control device 3 controls the heat generating component 2 to heat the smoke oil in a pre-controlled temperature range.

[0053] Since in other embodiments, there is a case where the temperature variation curve of the heat generating component 2 stored by the storage module 35 is automatically cleared after being separated from the power supply device 1 (here, the separation finger is broken mechanically connected), the heating fog The control method may further include steps before step A:

[0054] determining whether a temperature change curve is stored in the storage module 35, if not, proceeding to step A, if yes, skipping step A, performing step ^

[0055] It is to be understood that the above technical features may be used in any combination without limitation.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the invention, and the equivalent structure or equivalent process transformations made by the specification and the drawings of the present invention may be directly or indirectly applied to others. The related technical fields are all included in the scope of patent protection of the present invention.
