[0047] The smoking device 2 is a handheld portable device, meaning that the user can hold and support the device with one hand without assistance. The smoking device 2 has a first end 26 (or proximal end) and a second end 27 (or distal end).

[0048] For example, the smoking rod 2 includes a smoking rod housing 23, a support frame 24, a smoking rod battery, a smoking rod circuit board 25, and at least two smoking rod electrodes 7;

[0049] The battery of the cigarette rod is disposed inside the outer shell 23 of the cigarette rod to store electrical energy and provide power when the cigarette rod 2 needs to heat the aerosol; the circuit board 25 of the cigarette rod is disposed inside the outer shell 23 of the cigarette rod and is electrically connected to the battery of the cigarette rod; the electrode 7 of the cigarette rod is disposed at the second end 27 of the cigarette rod; wherein, the electrode 7 of the cigarette rod is electrically connected to the circuit board 25 of the cigarette rod and the first drive assembly 3 respectively, for charging the battery of the cigarette rod; and for data interaction with the charging box 1; the support frame 24 is disposed inside the outer shell 23 of the cigarette rod.

[0050] like Figure 2 As shown, in some embodiments, the first driving component 3 includes an electromagnet unit, a moving iron core 13, a magnet bracket 14, and at least two elastic electrodes 15; the bottom end of the moving iron core 13 is connected to the electromagnet unit, and the top end is connected to and passes through the magnet bracket 14; at least two electrode magnets 16 are provided on the magnet bracket 14; each electrode magnet 16 is provided with a first through hole 18; the elastic electrodes 15 are all disposed in the first through holes 18 and pass through the magnet bracket 14; wherein, at least two elastic electrodes 15 are respectively electrically connected to the electrodes of the integrated circuit board 4 and the cigarette rod 2.

[0051] In this embodiment, the magnet support 14 is made of insulating material to prevent short circuits between electrodes; the electrode magnet 16 is set as a ring magnet, and the elastic electrode 15 is placed inside the ring of the electrode magnet 16. When the cigarette rod 2 is placed into the charging cavity of the charging box 1, the cigarette rod electrode 7 set at the second end 27 of the cigarette rod is attracted by the magnetic force of the electrode magnet 16, so that the end faces of the two form a continuous adsorption force. At this time, the cigarette rod electrode 7 compresses the elastic electrode 15, so that the elastic electrode 15 ensures good contact with the cigarette rod electrode 7 under the compression reaction force of the spring inside it, so that the charging box 1 can charge the cigarette rod 2 through the elastic electrode 15 when the cigarette rod 2 is low on power, and realize other functions such as signal transmission and data interaction.

[0052] Specifically, the electromagnet unit comprises an electromagnet shell 10, a fixed iron core 11 arranged at the bottom of the electromagnet shell 10, and a coil 12 sleeved outside the fixed iron core 11; the moving iron core 13 is slidably connected in the coil 12 and moves relative to the fixed iron core 11 under the action of a magnetic field; wherein the fixed iron core 11 is connected with the bottom end of the moving iron core 13; the input end of the coil 12 is electrically connected with the output end of the integrated circuit board 4.

[0053] In some embodiments, the second driving assembly comprises a first magnetic member 8 and a second magnetic member 9 which repel each other, wherein the first magnetic member 8 is arranged in the battery cavity and embedded in the battery support 5, and the second magnetic member 9 is arranged on the inner wall of the tobacco rod 2; wherein the second magnetic member is fixed on the inner wall of the tobacco rod shell by the support frame 24.

[0054] In this embodiment, the magnetic repulsion force between the first magnetic member 8 and the second magnetic member 9 is greater than the attraction force of the electrode magnet 16 to the electrode of the tobacco rod 2; at the same time, the magnetic repulsion force between the first magnetic member 8 and the second magnetic member 9 is also greater than the gravity of the tobacco rod 2 itself.

[0055] In some embodiments, the charging box 1 further comprises a charging detection module electrically connected with the integrated circuit board 4, which is used to detect the battery voltage of the tobacco rod 2 to determine whether the tobacco rod 2 needs to be charged.

[0056] When the electrode of the tobacco rod 2 contacts the elastic electrode 15, the plurality of elastic electrodes 15 of the charging box 1 change from open circuit to closed circuit, the charging box 1 will automatically receive a signal, and the battery capacity is determined by detecting the battery voltage, so as to determine whether the battery is in a low power state. If it is found that there is a low power state, the charging box 1 starts to charge the battery of the tobacco rod 2.

[0057] In some embodiments, the smoking set further comprises a key assembly, the key assembly comprising a key plate 20 and at least one key 21, the input end of the key plate 20 being electrically connected with the output end of the key 21, and the output end of the key plate 20 being electrically connected with the input end of the integrated circuit board 4.

[0058] Specifically, a key through hole is formed at the top end of the battery cavity, one end of the key 21 is connected with the key plate 20 arranged on the top wall of the battery cavity, and the other end of the key 21 extends to the outside of the battery cavity through the key through hole.

[0059] In some embodiments, the smoking set further comprises a soft circuit board 22; the soft circuit board 22 is arranged in the battery cavity, the input end of the soft circuit board 22 is electrically connected with the output end of the key plate 20, and the output end of the soft circuit board 22 is electrically connected with the integrated circuit board 4.

[0060] When the user needs to take out the cigarette rod 2, the button 21 on the charging box 1 is triggered, the button plate 20 sends a signal, and the signal is transmitted to the integrated circuit board 4 through the soft circuit board 22. The integrated circuit board 4 adjusts the power supply current direction of the electromagnet unit, changes the current direction of the coil 12 to the moving iron core 13, makes the coil 12 generate an opposite magnetic direction, drives the moving iron core 13 to drive the first end 26 of the cigarette rod to displace a distance in the direction of the charging cavity opening 6, and realizes the first stage displacement of the cigarette rod 2, as shown in Figure 3 the first displacement position of the cigarette rod 2; at this time, the second magnetic member 9 originally located below the first magnetic member 8 is pushed to the right side of the first magnetic member 8, the repulsion force between the two magnetic members reaches the maximum, the repulsion force drives the first end 26 of the cigarette rod 2 to continue to displace in the direction of the charging cavity opening 6, until the length of the cigarette rod 2 extending out of the charging box 1 is enough for the user to normally grasp, realizing the second stage displacement of the cigarette rod 2, as shown in Figure 4 the second displacement position of the cigarette rod 2; at the same time, when the second driving assembly drives the cigarette rod 2, the elastic electrode 15 is in an open circuit state, the power supply current direction of the electromagnet unit changes, the electromagnet unit converts the signal, and the moving iron core 13 displaces to reset to the opposite direction and is attracted to the fixed iron core 11.

[0061] It should be noted that, since the repulsion force between the magnetic members in the second driving assembly is greater than the gravity of the cigarette rod 2 in the embodiment, when the length of the cigarette rod 2 extending out of the charging box 1 is enough for the user to normally grasp, the cigarette rod 2 will always be suspended when the user does not grasp the cigarette rod 2.

[0062] When the user needs to charge, the second end 27 of the cigarette rod 2 is placed into the charging cavity through the charging cavity outlet, and the user needs to apply a little pressure to the cigarette rod 2, so that the pressure and the gravity of the cigarette rod 2 are greater than the repulsion force between the magnetic members in the second driving assembly. At this time, the repulsion force between the magnetic members will be converted into a pushing force to continue to place the cigarette rod 2 into the charging cavity, realizing the displacement of the cigarette rod 2 from Figure 4 the second displacement position of the cigarette rod 2 to Figure 1 the position of the cigarette rod 2, at this time, the electrode of the cigarette rod 2 is in contact with the elastic electrode 15, realizing charging or data exchange.

[0063] In some embodiments, the cigarette rod electrode 7 is made of a material with high magnetic permeability and excellent electrical conductivity, and the material of the cigarette rod electrode 7 includes iron, nickel, permalloy, iron-cobalt (FeCo) alloy, iron-aluminum alloy, and surface silver or gold plated ferromagnetic material, etc.

[0064] In some embodiments, a protrusion is arranged on the surface of the cigarette rod shell, and a groove corresponding to the protrusion is arranged on the inner wall of the charging cavity, which is used to limit the insertion angle and position of the cigarette rod 2, so that the side wall of the cigarette rod 2 fixed with the second magnetic member 9 is opposite to the battery support 5 fixed with the first magnetic member 8.

[0065] Embodiment 2

[0066] As shown in Figures 5-8 , the embodiment provides an electromagnetic pop-up heating cigarette device, which is different from the embodiment 1 in that the first driving assembly 3 comprises an electromagnet unit, a moving iron core 13, at least two insulating supports 17 and at least two elastic electrodes 15.

[0067] For example, the moving iron core 13 has a T-shaped structure, the bottom end of the moving iron core 13 is connected with the electromagnet unit, the insulating supports 17 are arranged through the top end of the moving iron core 13, the second through holes 19 are arranged on the insulating supports 17, the elastic electrodes 15 are arranged in the second through holes 19 and penetrate the top end of the moving iron core 13, and the at least two elastic electrodes 15 are electrically connected with the integrated circuit board 4 and the cigarette rod electrode 7 respectively.

[0068] Specifically, the insulating supports 17 are made of insulating materials and fasten the elastic electrodes 15 through the second through holes 19.

[0069] In the embodiment, when the user needs to take out the cigarette rod 2, the button 21 on the charging box 1 is triggered to make the button plate 20 send a signal, the signal is transmitted to the integrated circuit board 4 through the soft circuit board 22, the integrated circuit board 4 adjusts the power supply current direction of the electromagnet unit, changes the current direction of the coil 12 to the moving iron core 13, makes the coil 12 generate an opposite magnetic direction, drives the moving iron core 13 to drive the first end 26 of the cigarette rod 2 to displace an end distance in the direction of the charging cavity opening 6, and realizes the first stage displacement of the cigarette rod 2, as shown in Figure 7 , the first stage displacement position of the cigarette rod 2; at this time, the second magnetic element 9 originally located below the first magnetic element 8 is pushed to the right side of the first magnetic element 8, the repulsion force between the two magnetic elements reaches the maximum, the repulsion force drives the first end 26 of the cigarette rod 2 to continue to displace in the direction of the charging cavity opening 6, until the length of the cigarette rod 2 extending out of the charging box 1 is enough for the user to normally grab, and realizes the second stage displacement of the cigarette rod 2, as shown in Figure 8 , the second stage displacement position of the cigarette rod 2; at the same time, when the second driving assembly drives the cigarette rod 2, the elastic electrodes 15 are in an open circuit state, the power supply current direction of the electromagnet unit changes, the electromagnet unit converts the signal, and the moving iron core 13 displaces to the opposite direction and resets to the attraction with the fixed iron core 11.

[0070] When the user needs to charge, the second end 27 of the cigarette rod 2 is placed into the charging cavity through the charging cavity outlet, the user needs to apply a little pressure to the cigarette rod 2, so that the pressure and the gravity of the cigarette rod 2 are greater than the repulsion force between the magnetic elements in the second driving assembly, at this time, the repulsion force between the magnetic elements will be converted into a pushing force to continue to place the cigarette rod 2 into the charging cavity, and realizes the displacement of the cigarette rod 2 from Figure 8 , the second stage displacement position of the cigarette rod 2 to Figure 5When the cigarette rod 2 is displaced to the position of the charging cavity opening 6, the cigarette rod electrode 7 is in contact with the elastic electrode 15, the elastic electrode 15 feeds back a signal to the integrated circuit board 4, the charging detection module detects the power of the cigarette rod battery, if the cigarette rod 2 is detected to be in a low power state, the elastic electrode 15 charges the cigarette rod battery, and at the same time, distributes current to the electromagnet unit, so that the coil 12 generates magnetism, the moving iron core 13 generates magnetic force, the moving iron core 13 is tightly adsorbed on the fixed iron core 11, and the moving iron core 13 generates magnetic force to adsorb the cigarette rod electrode 7, so that the elastic electrode 15 is fully compressed to reliably contact the cigarette rod electrode 7, thereby the charging case 1 stably charges the cigarette rod 2.

[0071] It should be noted that when the cigarette rod 2 is fully charged, the current direction of the integrated circuit board 4 supplying power to the electromagnet does not change, but the current supplied to the electromagnet is reduced, only to maintain the adsorption of the cigarette rod 2, so as to ensure that the static power consumption of the product is not too large.

[0072] In summary, the two-stage driving force is provided in the embodiment, i.e., the first driving assembly 3 drives and the second driving assembly drives, so that the cigarette rod 2 is automatically and smoothly displaced when taken out. The first driving assembly 3 preliminarily pushes the cigarette rod 2 to displace in the direction of the charging cavity opening 6, so as to realize the first-stage displacement of the cigarette rod 2, and then the second driving assembly uses the repulsive force between the magnetic members to make the cigarette rod 2 perform the second-stage displacement, until the length of the cigarette rod 2 extending out of the charging cavity is long enough for the user to normally grasp, thereby significantly optimizing the convenience and comfort of the user when taking the cigarette rod 2, and improving the overall use experience of the user. In the embodiment, after the cigarette rod 2 is taken out, the electromagnet unit can intelligently convert signals to drive the electromagnet moving iron core 13 to reversely move to the reset position, so as to realize the automatic reset function of the cigarette rod 2, and effectively reduce the operation steps of the user. In the embodiment, the repulsive force between the magnetic members in the second driving assembly is greater than the gravity of the cigarette rod 2, so that the cigarette rod 2 can be stably suspended at a specific position when not taken out in time, thereby avoiding the problem of falling due to gravity, and further improving the safety and stability of the equipment.
