It should be understood that one of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.
[0030] like Figures 1 to 4 As shown, on the one hand, the embodiment of the present application provides a heating cigarette tube 1, which includes a cigarette tube body 10 and multiple electroheating elements 20, which can better realize segmented heating, increase the battery life of the electronic cigarette device, make the cigarettes heated and burned more evenly, and effectively improve the user experience of the electronic cigarette device.
[0031] Here, the cigarette tube body 10 is provided with a lumen 11 for accommodating cigarettes, and the side walls of the lumen 11 can be made of heat-conducting material. A plurality of electric heating elements 20 are sequentially arranged on the cigarette tube body 10 along the extension direction of the lumen 11. The electric heating element 20 is configured to generate heat when the power is on and stop generating heat when the power is off. The electric heating element 20 can be made of different materials, and can be made of materials such as nickel-chromium alloy, nickel-iron alloy, stainless steel, iron-chromium-aluminum, titanium metal, nickel metal, etc., with a temperature coefficient of resistance TCR (Temperature Coefficient of Resistance) greater than or equal to 1000 / °C at 20°C. This embodiment of the present application does not limit this. For example, the electric heating element 20 can have a bent circuit structure.
[0032] In this way, the position where the cigarette is about to burn can be determined according to the burning rate of the cigarette, and the electric heating element 20 corresponding to the position where the cigarette is about to burn can be controlled to be powered on and heated, and the electric heating element 20 corresponding to the position where the cigarette has burned out can be controlled to be powered off and stop heating, so that only the electric heating element 20 located at the target position is controlled to be powered on and heated, thereby reducing the power consumption of the electronic smoking device and increasing the battery life of the electronic smoking device, and making the heating position of the heating pipe 1 consistent with the position where the cigarette is about to burn, effectively improving the user experience of the electronic smoking device.
[0033] In some embodiments, multiple electric heating elements 20 can be controlled to be energized and de-energized sequentially along the extension direction of the lumen 11. In this way, according to the burning state of the cigarette, the electric heating elements 20 at corresponding positions can be energized, while the electric heating elements 20 corresponding to the position where the cigarette has been burned can be de-energized, or the electric heating elements 20 at other positions can be controlled to remain de-energized, thereby achieving energy-saving control.
[0034] like Figure 1 and Figure 2As shown, in other embodiments, the multiple electroheating elements 20 may include at least one first electroheating element 21, and the first electroheating element 21 may slide along the extension direction of the tubular cavity 11 so that the first electroheating element 21 and the adjacent electroheating element 20 are at least partially stacked in the radial direction along the tubular cavity 11. When the first electric heating element 21 and the adjacent electric heating element 20 are at least partially stacked, and the first electric heating element 21 and the adjacent electric heating element 20 are both powered on and heating, the heating power of the stacked area of the first electric heating element 21 and the adjacent electric heating element 20 is larger and the heating temperature is higher, while the heating power of the area on the first electric heating element 21 that is not stacked with the adjacent electric heating element 20 is smaller, and the heating power of the area on the adjacent electric heating element 20 that is not stacked with the first electric heating element 21 is smaller, so that the area with larger heating power corresponds to the position where the cigarette is about to burn, so that the cigarette can be heated and burned better, and the area with smaller heating power corresponds to the position where the cigarette has been burned out and the position where the cigarette is not about to burn, so that the residual heat can be better used to heat and burn the position where the cigarette is about to burn, and the smaller heating power can be used to preheat the position where the cigarette is not about to burn, thereby achieving a better combustion effect.
[0035] like Figure 3 As shown, in some examples, a plurality of closed cavities 12 may be provided on the sidewall of the cigarette tube body 10. The plurality of closed cavities 12 are sequentially spaced apart along the radial direction of the tube lumen 11, and two adjacent closed cavities 12 are at least partially stacked in the radial direction of the tube lumen 11. At least one electric heating element 20 is provided in each closed cavity 12, and the electric heating element 20 provided in at least one closed cavity 12 is a first electric heating element 21. The first electric heating element 21 can slide in the closed cavity 12 in which it is located along the extension direction of the tube lumen 11, so that the first electric heating element 21 and the electric heating element 20 in the adjacent closed cavity 12 are at least partially stacked in the radial direction of the tube lumen 11.
[0036] The shape of the closed cavity portion 12 can be determined according to actual needs, and the embodiments of the present application do not limit this. For example, the closed cavity portion 12 can be an annular cavity, which extends along the circumference of the tube cavity 11 to be arranged around the tube cavity 11. For example, the electric heating element 20 can slide along the circumference of the tube cavity 11 to change the position of the electric heating element 20 in the circumference of the tube cavity 11, so as to generate heat at different positions in the circumference of the tube cavity 11 to heat the corresponding positions on the cigarette along the circumference of the tube cavity 11; for example, the electric heating element 20 can extend along the circumference of the tube cavity 11 to be arranged around the tube cavity 11, so that the electric heating element 20 is a heating element with an annular structure.
[0037] like Figure 4As shown, for example, the closed cavity portion 12 may include a plurality of closed sub-cavities 121. The plurality of closed sub-cavities 121 are sequentially spaced along the circumference of the tubular cavity 11. The closed sub-cavities 121 may extend along the extension direction of the tubular cavity 11, and a first electric heating element 21 is respectively provided in each closed sub-cavity 121. Here, each first electric heating element 21 may slide along the extension direction of the tubular cavity 11, so that the first electric heating element 21 and the electric heating element 20 of the closed sub-cavity 121 in the adjacent closed cavity portion 12 are at least partially stacked in the radial direction along the tubular cavity 11.
[0038] For example, the spacer between two adjacent closed sub-cavities 121 in the inner closed cavity 12 is a first spacer 122, and the closed sub-cavities 121 in the outer closed cavity 12 are arranged corresponding to the first spacer 122. In this way, the closed sub-cavities 121 in two adjacent closed cavities 12 can be alternately arranged along the circumference of the lumen 11, thereby increasing the diversity of the control methods for the electric heating element 20.
[0039] like Figures 5 to 7 As shown, in some other embodiments, a plurality of electric heating elements 20 are sequentially spaced apart along the extension direction of the tube cavity 11; the heated tobacco pipe 1 may include a second electric heating element 30, which is disposed on a side of the plurality of electric heating elements 20 away from the tube cavity 11. The second electric heating element 30 can be slidably switched among the plurality of electric heating elements 20 along the extension direction of the tube cavity 11, so that the second electric heating element 30 is conductively connected to an electric heating element 20 at a target position and drives the electric heating element 20 at the target position to generate heat, and the second electric heating element 30 is disconnected from the remaining electric heating elements 20, and the remaining electric heating elements 20 are powered off and stop generating heat. In other words, when it is necessary to control the electric heating element 20 at the target position to be energized and heated, the second electric heating element 30 can be controlled to slide to the target position, so that the second electric heating element 30 is electrically connected to one of the electric heating elements 20 at the target position, so that the energized second electric heating element 30 drives the electric heating element 20 at the target position to be energized and heated, while the electric heating elements 20 at the remaining positions are separated from the second electric heating element 30 and de-energized. In this way, the position at which the cigarette is about to burn can be determined based on the burning rate of the cigarette, and the electric heating element 20 corresponding to the position at which the cigarette is about to burn can be energized and heated, while the electric heating element 20 corresponding to the position at which the cigarette has burned out can be de-energized and stopped heating. As a result, only the electric heating element 20 at the target position is energized and heated, reducing the power consumption of the electronic cigarette device and increasing the battery life of the electronic cigarette device. In addition, the heating position of the heated tobacco pipe 1 is aligned with the position at which the cigarette is about to burn, effectively improving the user experience of the electronic cigarette device.
[0040] In some examples, the second electroheating element 30 may be provided with a first electrode 31, a second electrode 32, a third electrode 33 and a fourth electrode 34, and the first electrode 31 and the second electrode 32 are electrically connected to the power supply 2 respectively. When the second electroheating element 30 slides to the target position, the third electrode 33 and the fourth electrode 34 are respectively in contact with the electroheating element 20 located at the target position, so that the second electroheating element 30 and the electroheating element 20 located at the target position are conductively connected; at the same time, the third electrode 33 and the fourth electrode 34 are respectively released from contact with the remaining electroheating elements 20, so that the second electroheating element 30 and the remaining electroheating elements 20 are spaced apart and disconnected, so that the remaining electroheating elements 20 are powered off and stop heating. Here, when the third electrode 33 and the fourth electrode 34 are respectively in contact with the electroheating element 20 located at the target position, the second electroheating element 30 can be connected in series or in parallel with the electroheating element 20 located at the target position, and this embodiment of the application is not limited to this.
[0041] In some examples, the second electroheating element 30 can be configured to slide at a sliding rate corresponding to the burning rate of the cigarette. Here, the second electroheating element 30 can be controlled to slide synchronously according to the burning rate of the cigarette, so that the heating position on the heating pipe 1 always corresponds to the position where the cigarette is about to burn. In this way, only the electroheating element 20 at the target position is controlled to be energized and heated, reducing the power consumption of the electronic cigarette device and increasing the battery life of the electronic cigarette device. In addition, the heating position of the heating pipe 1 is consistent with the position where the cigarette is about to burn, effectively improving the user experience of the electronic cigarette device.
[0042] For example, the burning rates of cigarettes of different brands / specifications can be predetermined. When smoking a cigarette using the heated cigarette tube 1 and the electronic smoking device in which it is located, the brand / specification information of the cigarette can be obtained, and the burning rate of the cigarette and the sliding rate of the second electroheating element 30 can be determined based on the brand / specification information of the cigarette, thereby controlling the second electroheating element 30 to slide synchronously with the burning rate of the cigarette.
[0043] The second electric heating element 30 can be made of various materials, such as nickel-chromium alloy, nickel-iron alloy, stainless steel, iron-chromium-aluminum, titanium, nickel, etc., with a temperature coefficient of resistance (TCR) greater than or equal to 1000 / °C at 20°C, and this embodiment of the present application is not limited thereto. For example, the second electric heating element 30 can have a bent circuit structure.
[0044] like Figures 1 to 6As shown, another embodiment of the present application provides an electronic smoking device, comprising a power supply 2 and a heating pipe 1 provided in any of the above embodiments. Here, the power supply 2 is used to supply power to the electroheating element 20, causing the electroheating element 20 to generate heat when powered. The electronic smoking device provided in the embodiment of the present application, with the above-mentioned heating pipe 1, can effectively achieve segmented heating, increase the battery life of the electronic smoking device, ensure more uniform heating and combustion of cigarettes, and effectively improve the user experience of the electronic smoking device.
[0045] The above is a detailed introduction to the heated tobacco pipe and electronic smoking device provided in the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of the present application. At the same time, for those skilled in the art, according to the ideas of the present application, there may be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present application.
