Detailed Implementation

[0028] The technical solution of a specific embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on this embodiment without inventive effort are within the scope of protection of this invention.

[0029] Example 1: As Figures 1 to 4 As shown, this invention provides an active heat dissipation module for electronic cigarettes, including a power unit and four coaxially stacked heat dissipation disks 102. Each heat dissipation disk 102 is a disc made of thermally conductive material, and each heat dissipation disk 102 has a plurality of through-axial flue holes 112. In this embodiment, the flue holes 112 are arranged in two annular arrays, with both the outer and inner annular arrays having six flue holes 112. For ease of control and adjustment, the corresponding flue holes 112 on the outer and inner annular arrays are on a radial line. Therefore, in this embodiment, for every 60 degrees relative rotation between two adjacent heat dissipation disks 102, the adjacent heat dissipation disks 102... The relative position of the flue holes 112 between the two will change cyclically; there is a certain gap between adjacent heat dissipation plates 102 to form a flue gap 114. The alternating flue holes 112 and flue gaps 114 constitute a heat dissipation flue for smoke to pass through; the power device is a stepper motor 108, which is connected to several heat dissipation plates 102 through a power switching mechanism. The power switching mechanism selects one or several heat dissipation plates 102 to be connected, so that the power device can drive one or more of the heat dissipation plates 102 to rotate, change the relative phase angle between two adjacent heat dissipation plates 102, thereby adjusting the length of the heat dissipation flue and realizing the adjustment of heat dissipation capacity.

[0030] It should be noted that the installation method of each heat sink 102 is not limited, as long as they are coaxial, partially rotatable, and meet the above-mentioned positional constraints.

[0031] As a preferred embodiment, the heat dissipation disc 102 is made of heat conductive plastic or metal material, which can improve the heat dissipation capacity of the heat dissipation disc 102, and the heat of the heat dissipation disc 102 itself can be dissipated to the air through the electronic cigarette shell or converted into electricity through the thermoelectric material, so that the heat is consumed. The heat conductive plastic is generally a high polymer material filled with heat conductive filler, and the heat conductive filler is generally graphite, carbon powder, etc. The base material is not limited and can be PC, PP, PPA, etc.

[0032] As a preferred embodiment, as shown in Figure 1 and Figure 3 , the present application provides an optimal power switching transmission mechanism, which comprises a shaft hole arranged at the center of each heat dissipation disc 102, a main shaft 110 penetrating all the heat dissipation discs 102, and an electronic clutch 111 connecting the main shaft 110 and each heat dissipation disc 102. The electronic clutch 111 is a clutch with a shaft hole, so that it can be freely penetrated by the main shaft 110. One end of the electronic clutch 111 is fixed on the main shaft 110 on one side of the corresponding heat dissipation disc 102 through a key 115 or a connecting piece. The other end of the electronic clutch 111 is fixed on the corresponding heat dissipation disc 102 through a connecting piece or a fastener. When a certain electronic clutch 111 is connected, the stepping motor 108 can drive the corresponding heat dissipation disc 102 to rotate through the main shaft 110.

[0033] The mounting and supporting mode of the heat dissipation disc 102 itself is not limited. For example, in order to prevent the support structure from affecting the flue gap, a rotating pair can be arranged near the center of the heat dissipation disc 102 to connect each heat dissipation disc 102 to each other to form a whole, or the entire heat dissipation disc 102 is embedded and installed in the shell of the electronic cigarette through a rotating pair (such as a sliding bearing). The main shaft 110 is connected to the stepping motor 108 through a shaft coupling.

[0034] The present application provides a heat dissipation flue length adjustment mode based on the embodiment, and defines the initial state, in which the flue holes 112 of the four heat dissipation discs 102 are aligned one by one, as shown in Figure 1 At this time, the flue holes 112 of the adjacent two heat dissipation discs 102 are straight through, and the heat dissipation flue length is in the shortest state. For certain two adjacent heat dissipation discs 102, a relative rotation of 60 degrees is one cycle, and the flue holes 112 are still in the aligned state. When rotated by 30 degrees, the flue gap between the adjacent heat dissipation discs 102 is the largest, as shown in Figure 4 the rightmost heat dissipation disc 102, Figure 4The middle arrow is a schematic diagram of flue gas flowing in the flue hole 112 and the flue gap; therefore, in this embodiment, the rotation angle between two adjacent heat dissipation discs 102 is 0-30 degrees, and it is meaningless to be larger, which will also increase the complexity of control; at the beginning, the initial state is used for heat dissipation, for example, the flue gas enters the flue hole 112 of the first heat dissipation disc 102, which is the high-temperature flue gas inlet, and the flue gas exits the flue hole 112 of the fourth heat dissipation disc 102, which is the low-temperature flue gas outlet; when it is detected that the temperature of the low-temperature flue gas outlet is too high and cannot meet the set value, that is, when the active heat dissipation module is insufficient in heat dissipation capacity, the electronic clutch 111 of the first heat dissipation disc 102 is connected, and the first heat dissipation disc 102 is driven to rotate by the stepping motor 108, and the remaining heat dissipation discs 102 remain stationary, and the length of the heat dissipation flue is increased to improve the heat dissipation capacity; when the first heat dissipation disc 102 rotates to 30 degrees, the temperature of the low-temperature flue gas outlet still cannot meet the set value, the electronic clutch 111 of the second heat dissipation disc 102 is connected, and the first and second electronic clutches 111 are kept synchronous rotation, and so on, until the relative phase angle between every two adjacent heat dissipation discs 102 is 30 degrees, and the heat dissipation flue reaches the maximum length; when the temperature of the low-temperature flue gas outlet is too low, it can be adjusted in the opposite direction. The above adjustment method is only an example, and the relative phase angle between the first heat dissipation disc 102 and the second heat dissipation disc 102 can also be adjusted by driving the second, third and fourth heat dissipation discs 102 to rotate together.

[0035] Embodiment 2: other parts are the same as embodiment 1, the difference is that the power switching mechanism is different, as shown in Figure 5 and Figure 6 , this embodiment provides a simple power switching mechanism, which includes a main shaft 110 connected with a power device, a part of the heat dissipation discs 102 are fixed discs 116, and the other part are rotating discs 117, the fixed discs 116 and the rotating discs 117 are sequentially and alternately distributed, for example, the odd-numbered heat dissipation discs 102 are fixed discs 116, and the even-numbered heat dissipation discs 102 are rotating discs 117, in this way, only rotating the even-numbered heat dissipation discs 102 can adjust the length of the heat dissipation flue within a certain range, and each heat dissipation disc 102 is provided with a shaft hole in the center, the main shaft 110 penetrates the shaft holes of all heat dissipation discs 102, the rotating disc 117 is connected with the main shaft 110 through gear meshing or key 115, and the power device drives the interval-distributed heat dissipation discs 102 to rotate through gear meshing, so as to adjust the length of the heat dissipation flue, the structure of this embodiment is simple, but the heat dissipation adjustment capacity is not as high as that of embodiment 1.

[0036] As a preferred embodiment, the inner wall of the flue hole 112 is provided with wrinkles for increasing the heat dissipation area.

[0037] Embodiment 3: as Figure 7As shown, this embodiment provides an electronic cigarette using the active heat dissipation module described in Embodiment 1 or Embodiment 2. The electronic cigarette includes a cylindrical shell, a mouthpiece 101 located at the outer end of the cylindrical shell, and an atomizer 103 and a cartridge 104 located inside the cylindrical shell. The mouthpiece 101 is connected to the atomizer 103 inside the cylindrical shell. The active heat dissipation module provided in Embodiment 1 or Embodiment 2 is installed between the cartridge 104 and the mouthpiece 101 inside the cylindrical shell. The end of the active heat dissipation module near the cartridge 104 is a high-temperature smoke inlet, and the end of the active heat dissipation module near the mouthpiece 101 is a low-temperature smoke outlet.

[0038] The cartridge 104 stores a certain amount of e-liquid for electronic cigarettes. When the user uses the device, the e-liquid in the cartridge 104 produces vapor under the action of the atomizer 103. When the user inhales, the mouthpiece 101 generates suction, causing the e-liquid in the cartridge 104 to enter the atomizer 103. The atomizer 103 generates high-temperature vapor, which enters from the high-temperature vapor inlet at the right end of the active cooling module and exits from the low-temperature vapor outlet at the left end of the active cooling module, becoming a low-temperature vapor that is acceptable to the user. Finally, it reaches the user's mouth through the mouthpiece 101, completing the entire electronic cigarette inhalation process. When the vapor temperature at the low-temperature vapor outlet is too high or too low, the heat dissipation capacity of the active cooling module is adjusted to stabilize the vapor temperature.

[0039] In a preferred embodiment, the electronic cigarette also includes a controller 107 and temperature sensors located at both ends of the active heat dissipation module. The temperature sensors can be thermocouples 109, which serve as temperature sensing elements and are attached to the air inlet and outlet of the active heat dissipation module to measure the temperature of the smoke in real time.

[0040] The controller 107 controls the start and stop of the power unit based on the collected inlet and outlet flue gas temperatures of the active heat dissipation module, and adjusts the heat dissipation capacity by adjusting the length of the heat dissipation flue, thereby realizing the automatic adjustment of the flue gas temperature entering the nozzle 101.

[0041] Example 4: Figure 7 As shown, this embodiment is an improvement on embodiment 3. Each heat sink 102 of the active heat dissipation module is provided with thermoelectric power generation material. The cylindrical shell is provided with a micro battery 105. The thermoelectric power generation material is connected to the micro battery 105 through wires and charging / discharging circuit. The micro battery 105 is used to power the stepper motor 108 and the atomizer 103.

[0042] As a preferred embodiment, a switch 106 can also be provided at the tail of the cylindrical shell of the electronic cigarette. The switch 106 can be used to turn the micro battery 105 on or off to turn the electronic cigarette on and off, saving power when it is not used for a long time.
