Example one
Referring to fig. 1 and fig. 2, a schematic structural diagram of an electronic cigarette 100 according to an embodiment of the present invention is shown, the electronic cigarette 100 includes a cigarette rod 10, a first heating member 11, a second heating member 12, and a main board (not shown), the cigarette rod 10 has an air inlet 10a, a cigarette outlet 10b, and an accommodating chamber 101 for accommodating tobacco 200, the first heating member 11 is disposed at the air inlet 10a, the second heating member 12 is disposed on a cavity wall of the accommodating chamber 101, the main board is electrically connected to the first heating member 11 and the second heating member 12, and the main board is configured to control the first heating member 11 and the second heating member 12 to heat the tobacco 200 to a predetermined temperature.
The tobacco 200 in fig. 1 and 2 is obscured by the tobacco rod 10, so the tobacco 200 is shown in phantom.
Wherein, the air inlet end 10a is used for supplying air into the accommodating cavity 101, and the smoke outlet end 10b is used for discharging smoke generated by the tobacco 200 out of the accommodating cavity 101. Alternatively, the tobacco rod 10 may be an elongated hollow rod-shaped structure, the hollow part of the tobacco rod 10 is the accommodating cavity 101, the two open ends of the tobacco rod 10 are the air inlet end 10a and the smoke outlet end 10b, respectively, and the accommodating cavity 101 is located between the air inlet end 10a and the smoke outlet end 10 b.
The preset temperature is the ideal heating temperature of the tobacco 200, and when the tobacco 200 is at the ideal heating temperature, the tobacco 200 can be fully delayed without burning. Optionally, the preset temperature may be a specific temperature value or a specific temperature interval, which is not specifically limited in this embodiment. The present embodiment is described by taking the preset temperature as the temperature interval, for example, the preset temperature is T 1 ~T 2 ,200℃≤T 1 ≤250℃,350℃≤T 2 Is less than or equal to 400 ℃. As shown in FIG. 3, FIG. 3 shows that the temperature T of the tobacco 200 is at the preset temperature T under the ideal condition 1 ~T 2 And (4) the following steps. In fig. 3, the abscissa (distance) represents the distance between each part of the tobacco and the first heating member 11, and the ordinate (temperature) represents the temperature of the tobacco 200.
In the related art, when the heating component of the electronic cigarette heats the tobacco, the heat action of the heating component mainly acts on the part of the tobacco close to the heating component, and the temperature rise of the part of the tobacco far away from the heating component transfers the heat of the heating component to the part of the tobacco far away from the heating component by virtue of air and/or heats the tobacco close to the heating component by virtue of the tobaccoHeat from portions of the element is transferred to portions of the tobacco remote from the heating element. That is, in the related art, when the heating component of the electronic cigarette heats the tobacco, the temperature of each part of the tobacco cannot be maintained at the preset temperature T as shown in fig. 3 1 ~T 2 In fact, the temperatures of the respective portions of tobacco are as shown in fig. 4, where the abscissa (distance) of fig. 4 represents the distance between each portion of tobacco and the first heating member 11, and the ordinate (temperature) represents the temperature of tobacco 200.
As can be seen from fig. 4, as the distance increases, the temperature of the tobacco 200 gradually decreases, and the temperature of a part of the tobacco 200 reaches a predetermined temperature. So, the partial temperature that the tobacco is close to the heating part is higher, and the partial temperature that the heating part was kept away from to the tobacco is lower, and this leads to the whole temperature inhomogeneous of tobacco, and the part that the tobacco is close to the heating part is overheated easily and leads to the condition of burnt to take place, and the part that the heating part was kept away from to the tobacco appears heating the insufficient condition easily, causes the waste of tobacco, and user's smoking experience is relatively poor.
Therefore, in the present embodiment, the tobacco 200 is heated by the first heating member 11, at this time, the temperature of the portion of the tobacco 200 close to the first heating member 11 is higher, and the temperature of the portion of the tobacco 200 far from the first heating member 11 is lower, and the second heating member 12 is used for performing compensation heating on the tobacco 200 so as to increase the temperature of the portion of the tobacco 200 far from the first heating member 11, so that the temperature of the whole tobacco 200 tends to be uniform, and the whole temperature of the tobacco 200 is relatively uniform. In addition, the main board can control the first heating component 11 and the second heating component 12 to make the temperature of the tobacco 200 reach the preset temperature, so that the situation that the tobacco 200 is burnt due to overheating or the tobacco 200 is wasted due to insufficient heating can be avoided. As shown in FIG. 5, FIG. 5 illustrates the temperature change of the tobacco 200 as the first heating member 11 heats the tobacco 200 while the second heating member 12 compensates for the heating of the tobacco 200. In fig. 5, the abscissa (distance) represents the distance between each part of the tobacco and the first heating member 11, and the ordinate (temperature) represents the temperature of the tobacco 200. As can be seen from fig. 5, the temperature of each portion of the tobacco 200 can be within the predetermined temperature by the compensation heating of the tobacco 200 by the second heating member 12.
In this embodiment, the main board is used for controlling the first heating element 11 and the second heating element 12 to heat the tobacco 200 to a predetermined temperature synchronously. For example, if the main board starts the first heating member 11 to heat the tobacco 200 first, the temperature difference between the portion of the tobacco 200 close to the first heating member 11 and the portion of the tobacco 200 far from the first heating member 11 gradually increases with the increase of the heating time, the temperature difference between the portions of the tobacco 200 is large before reaching the preset temperature, and in order to make the temperatures of the portions of the tobacco 200 tend to be uniform, when the main board starts the second heating member 12 to heat the tobacco 200, the second heating member 12 needs to set a large heating power, so that the portion of the tobacco 200 with a low temperature can be compensated and heated in a short time, so that the temperatures of the portions of the tobacco 200 tend to be uniform. Thus, when the first heating member 11 and the second heating member 12 heat the tobacco 200 synchronously, the second heating member 12 does not need to set a higher heating power, the energy consumption of the electronic cigarette 100 can be reduced, and the temperatures of the parts of the tobacco 200 can tend to be consistent relatively quickly.
Illustratively, the first heating member 11 and the second heating member 12 have a distance therebetween along the length direction x of the cigarette rod 10. Thus, when the first heating member 11 and the second heating member 12 heat the tobacco 200, the portion of the tobacco 200 close to the first heating member 11 is mainly heated by the first heating member 11, but is not substantially heated by the second heating member 12, and the situation that the temperature is too high due to the overlapping of the heating action of the first heating member 11 and the second heating member 12 on the portion of the tobacco 200 close to the first heating member 11 is avoided.
In some embodiments, as shown in fig. 2, the electronic cigarette 100 includes a plurality of second heating members 12, and the plurality of second heating members 12 are sequentially spaced along the length direction x of the cigarette rod 10. Considering that the first heating member 11 heats the tobacco 200, the temperature of the portion of the tobacco 200 close to the first heating member 11 is higher, and the heat action of the first heating member 11 on the tobacco 200 decreases as the portion moves away from the first heating member 11, that is, the temperature of each portion of the tobacco 200 decreases as the tobacco 200 moves away from the first heating member 11. Therefore, in the present embodiment, by providing the plurality of second heating members 12, each of the second heating members 12 can heat each portion of the tobacco 200 in a direction away from the first heating member 11, and thus, by adjusting the temperatures of the plurality of second heating members 12, for example, the temperatures of the plurality of second heating members 12 increase with distance from the first heating member 11, the temperatures of the respective portions of the tobacco 200 tend to be uniform, and the overall temperature of the tobacco 200 is uniform. Two adjacent second heating members 12 are disposed at intervals along the longitudinal direction x of the cigarette rod 10. Therefore, the mutual influence of the thermal action generated by two adjacent second heating members 12 can be avoided, which is beneficial for the mainboard to control the plurality of second heating members 12 and adjust the temperature of each second heating member 12.
For example, the first heating member 11 may be a heating wire or a heating block, and the second heating member 12 may be a heating wire or a heating sheet, and the embodiment is not particularly limited thereto.
As an alternative embodiment, the second heating member 12 is ring-shaped, and the second heating member 12 is disposed around the cavity wall of the accommodating cavity 101. In this way, the second heating member 12 can heat the tobacco 200 in all directions around the circumference, and has high heating efficiency and uniform heat action on the tobacco 200.
As another alternative embodiment, the second heating member 12 includes a plurality of sub-heating portions (not shown), and the sub-heating portions are disposed at intervals around the cavity wall of the accommodating cavity 101. In this way, when the plurality of heating portions of the second heating member 12 heat the tobacco 200, it is possible to avoid the occurrence of local overheating of the tobacco 200. The present embodiment provides various structures of the second heating component 12, which can be selected according to actual situations, and the present embodiment is not limited to this.
In some embodiments, the second heating member 12 is provided with a temperature sensor 13, the temperature sensor 13 is electrically connected to the main board, and the temperature sensor 13 is used for detecting the temperature of the tobacco 200. Utilize temperature sensor 13 to detect the temperature of tobacco 200 to give the mainboard with temperature information transfer, like this, the mainboard can acquire the temperature of tobacco 200 in real time, judges thereby whether the temperature of the tobacco 200's that second heating part 12 corresponds the heating reaches in the preset temperature, and then through the temperature of real-time adjustment second heating part 12, can improve the precision that the mainboard carries out the regulation to the temperature of second heating part. When the electronic cigarette 100 of this embodiment has a plurality of second heating components 12, each corresponding second heating component 12 should be provided with a temperature sensor 13, so as to detect the temperature of a plurality of second heating components 12 through a plurality of temperature sensors 13, whereby, the mainboard can judge whether the temperature of a plurality of parts of the tobacco 200 reaches the preset temperature, finely adjust the temperature of a plurality of second heating components 12, and make the overall temperature of the tobacco 200 more uniform.
In some embodiments, the main board is used for controlling the first heating member 11 to heat the tobacco 200 at a constant temperature, and for controlling the second heating member 12 to heat the tobacco 200 at a variable temperature, so that the temperature of each portion of the tobacco 200 reaches a preset temperature. In this way, the first heating member 11 is in a constant temperature state, the heating effect of the first heating member 11 on the tobacco 200 is constant, the temperature of the portion, close to the first heating member 11, of the tobacco 200 can reach the preset temperature by controlling the temperature of the first heating member 11, the temperature of the portion, far away from the first heating member 11, of the tobacco 200 is reduced along with the distance from the first heating member 11, and the temperature of the portion, far away from the first heating member 11, of the tobacco 200 can always reach the preset temperature by adjusting the temperature of the second heating member 12. The temperatures of the first heating member 11 and the second heating member 12 may be the same or different, and the temperatures of the second heating members 12 may be the same or different, which is not specifically limited in this embodiment.
In this embodiment, during the process that the main board controls the first heating member 11 and the second heating member 12 to heat the tobacco 200 to the preset temperature, the portions of the tobacco 200 sequentially reach the preset temperature from the position far away from the first heating member 11 to the position close to the first heating member 11.
For example, when the electronic cigarette 100 has the first heating member 11 and the second heating member 12, referring to fig. 1 again, the tobacco 200 has a first portion 201 corresponding to the first heating member 11 and a second portion 202 corresponding to the second heating member 12, and the main board is used for controlling the first heating member 11 to heat the first portion 201 and controlling the second heating member 12 so that the second portion 202 and the first portion 201 sequentially reach a preset temperature along the direction from the smoke outlet end 10b to the air inlet end 10 a. Wherein the first heating element 11 mainly heats the first portion 201 (the portion close to the first heating element 11), while the second portion 202 is heated by the first heating element 11 under the heat transfer (via air or tobacco itself), but the heating effect is weaker than that of the first portion 201, and the second heating element 12 heats the second portion 202. If the temperature of the first portion 201 reaches the preset temperature first, the temperature of the second portion 202 may exceed the preset temperature when the second portion 202 is heated, and therefore, in the present embodiment, the first heating member 11 and the second heating member 12 are controlled by the main board, so that when the two heat the tobacco 200, the second portion 202 of the tobacco 200 reaches the preset temperature range in preference to the first portion 201, and thus, the occurrence of the situation that the partial temperature of the tobacco 200 exceeds the preset temperature can be avoided.
When the electronic cigarette 100 has the first heating component 11 and the plurality of second heating components 12, referring to fig. 2 again, the tobacco 200 has a third portion 203 corresponding to the first heating component 11 and fourth portions 204 corresponding to the plurality of second heating components 12 one by one, and the main board is configured to control the first heating component 11 to heat the third portion 203 and to control each second heating component 12 to heat each corresponding fourth portion 204, so that the plurality of fourth portions 204 and the plurality of third portions 203 sequentially reach a preset temperature along the direction from the smoke outlet end 10b to the air inlet end 10 a. For example, when there are two second heating members 12, the tobacco 200 has two fourth portions 204, and the two heating members 12 respectively heat the two fourth portions 204, and at this time, one of the two fourth portions 204 close to the third portion 203 is overlapped by the heat from the first heating member 11 and one second heating member 12, and the other of the two fourth portions 204 far from the third portion 203 is overlapped by the heat from the first heating member 11 and two second heating members 12, the temperature rising speed of the two fourth portions 204 is greater than that of the third portion 203, and the temperature rising speed of one of the two fourth portions 204 far from the third portion 203 is greater than that of one of the two fourth portions 204 close to the third portion 203. Therefore, according to the temperature of one of the two fourth portions 204 far from the third portion 203 and the temperature of one of the two fourth portions 204 near the third portion 203 and the temperature of the third portion 203 sequentially reach the preset temperature interval, the situation that the temperature of some portions of the tobacco 200 reaches the preset temperature and the temperature of some portions of the tobacco 200 exceeds the preset temperature can be avoided.
Illustratively, the electronic cigarette 100 further comprises a filter 14, and the filter 14 is disposed at the smoke outlet end 10b and is used for filtering smoke discharged from the smoke outlet end 10 b. Like this, through smog, tar and the suspended particles in the filter tip 14 filtration flue gas, can reduce the harm of flue gas to the user, user uses and experiences the preferred.
According to the electronic cigarette 100 provided by the first embodiment of the invention, the containing cavity 101 of the cigarette rod 10 contains the tobacco 200, the first heating component 11 arranged at the air inlet end 10a of the cigarette rod 10 and the second heating component 12 arranged on the cavity wall of the containing cavity 101 are utilized to heat the tobacco 200, so that the tobacco 200 generates smoke, and the smoke can be discharged from the containing cavity 101 from the smoke outlet end 10b of the cigarette rod 10 for a user to suck. Simultaneously, be connected through mainboard and first heating part 11 and second heating part 12 electricity, utilize first heating part 11 of mainboard control and second heating part 12 for in the temperature of tobacco 200 reaches preset temperature, like this, second heating part 12 can compensate the lower part of heating tobacco 200 temperature, makes tobacco 200 wholly be heated comparatively evenly, can avoid appearing partly burnt or the insufficient condition of heating takes place.
