Description

Technical Field

[0001] The invention belongs to the technical field of smoking articles, and in particular relates to an electromagnetic ejection heating cigarette device. Background Art

[0002] Heat-Not-Burn (HNB), as an innovative tobacco product, has gradually gained favor among consumers around the world in recent years. Its working principle is to efficiently convert battery energy into heat energy, accurately heat the aerosol generator within a specific time window, and release the aerosol without reaching the ignition point. Compared with the combustion method of traditional cigarettes, this heating process can significantly reduce the release of harmful substances, thereby providing users with a healthier and safer smoking experience.

[0003] As consumers become more health conscious and more convenient, the design of heated cigarette devices is gradually moving towards miniaturization and portability. However, while pursuing compact products, how to ensure sufficient battery life has become an urgent problem to be solved. Traditionally, smaller battery size often means shorter battery life, which to some extent limits the convenience of use and user experience of heated cigarette devices.

[0004] In order to resolve the contradiction between miniaturization and battery life, the industry generally adopts a split design strategy: the core heating component has a built-in small-size battery to ensure the portability of the product, and is equipped with a charging box with a larger battery capacity. The two together form a whole that is both portable and detachable. Users can flexibly combine or split the heating device and the charging box according to their personal habits and usage scenarios. Although split-type heated cigarette devices have achieved some success in the market, they still face challenges in practical applications, especially how to achieve fast and stable combination and separation between the heating device and the charging box, which has become a difficult problem that the current design urgently needs to overcome.

[0043] Example 1

[0044] like Figure 1 As shown, this embodiment provides an electromagnetic pop-up heating cigarette device, including a charging box 1 and a cigarette rod 2;

[0045] Exemplarily, the charging box 1 includes a box body, a battery assembly, a first drive assembly 3, a second drive assembly and an integrated circuit board 4; a battery holder 5 is provided inside the box body, forming a battery cavity for accommodating the battery assembly; wherein the integrated circuit board 4 is provided inside the box body, the input end of the integrated circuit board 4 is electrically connected to the output end of the battery assembly, and the output end of the integrated circuit board 4 is electrically connected to the input end of the first drive assembly 3; the first drive assembly 3 is provided at the bottom of the box body, and the first drive assembly 3 is respectively connected to the outer wall of the battery cavity and the inner wall of the box body, enclosing a charging cavity with an opening at the top.

[0046] Heating cigarette devices can also be called "heating non-burning cigarette devices", "low-temperature cigarette devices", "devices for vaporizing tobacco products", etc. Heating non-burning cigarettes or low-temperature cigarettes are a new type of tobacco products. Its definition can be summarized as: a device that uses an electronic device to heat an aerosol generator within a specific time and give specific heat energy to the aerosol generator to generate an aerosol. Therefore, the features disclosed in this article are also applicable to devices designed to vaporize any aerosol generating substrate.

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

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

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

[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 arranged on the magnet bracket 14; the electrode magnets 16 are each provided with a first through hole 18; the elastic electrodes 15 are each arranged in the first through hole 18 and pass through the magnet bracket 14; wherein, at least two elastic electrodes 15 are respectively electrically connected to the integrated circuit board 4 and the cigarette rod 2 electrodes.

[0051] In this embodiment, the magnet bracket 14 is made of insulating material to prevent short circuit between electrodes; the electrode magnet 16 is set as an annular magnet, and the elastic electrode 15 is placed in the ring of the electrode magnet 16. When the cigarette rod 2 is placed in the charging cavity of the charging box 1, the cigarette rod electrode 7 set at the second end 27 of the cigarette rod is subjected to the magnetic attraction of the electrode magnet 16, so that a continuous adsorption force is formed on the end faces of the two. 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 its internal spring, so that the charging box 1 can charge the cigarette rod 2 through the elastic electrode 15 when the cigarette rod 2 is out of power, and realize other functions such as signal transmission and data interaction.

[0052] Specifically, the electromagnet unit includes an electromagnet housing 10, a fixed iron core 11 arranged at the bottom of the electromagnet housing 10, and a coil 12 sleeved on the outside of 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 the magnetic field; wherein the fixed iron core 11 is connected to the bottom end of the moving iron core 13; the input end of the coil 12 is electrically connected to the output end of the integrated circuit board 4.

[0053] In some embodiments, the second driving assembly includes a first magnetic member 8 and a second magnetic member 9 that repel each other magnetically, wherein the first magnetic member 8 is disposed in the battery cavity and embedded in the battery holder 5, and the second magnetic member 9 is correspondingly disposed on the inner wall of the cigarette rod 2. The second magnetic member is fixed to the inner wall of the cigarette rod housing through a support frame 24;

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

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

[0056] Among them, when the electrode of the cigarette rod 2 contacts the elastic electrode 15, several elastic electrodes 15 of the charging box 1 change from open circuit to pass circuit, and the charging box 1 will automatically receive the signal, judge the battery capacity by detecting the battery voltage, and thus determine whether the battery is low in power. If a low power situation is found, the charging box 1 is started to charge the battery of the cigarette rod 2.

[0057] In some embodiments, the smoking device further comprises a key assembly, the key assembly comprising a key board 20 and at least one key 21, the input end of the key board 20 is electrically connected to the output end of the key 21, and the output end of the key board 20 is electrically connected to the input end of the integrated circuit board 4;

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

[0059] In some embodiments, the smoking device further includes a soft circuit board 22 ; the soft circuit board 22 is disposed in the battery cavity, the input end of the soft circuit board 22 is electrically connected to the output end of the key board 20 , and the output end of the soft circuit board 22 is electrically connected to the integrated circuit board 4 .

[0060] When the user needs to take out the cigarette rod 2, by triggering the button 21 on the charging box 1, the button board 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 direction of the power supply current to the electromagnet unit, changes the current direction of the coil 12 to the moving iron core 13, and makes the coil 12 produce the opposite magnetic direction, driving the moving iron core 13 to drive the first end 26 of the cigarette rod to move toward the charging chamber opening 6 by one end distance, so as to realize the first-level displacement of the cigarette rod 2, such as Figure 3 The middle cigarette rod 2 is at the first displacement position; at this time, the second magnetic member 9 originally located below the first magnetic member 8 is pushed to the positive side of the first magnetic member 8, and the repulsive force between the two magnetic members reaches the maximum, and the repulsive force drives the first end 26 of the cigarette rod 2 to continue to move toward the charging chamber opening 6 until the length of the cigarette rod 2 extending out of the charging box 1 is enough for the user to grab it normally, thereby realizing the second displacement of the cigarette rod 2. Figure 4 At the second displacement position of the middle cigarette rod 2; at the same time, when the second driving component 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 moves in the opposite direction and resets to attract the fixed iron core 11.

[0061] It should be noted that since the repulsive force between the magnetic parts in the second drive assembly in this embodiment is greater than the gravity of the cigarette rod 2, when the length of the cigarette rod 2 extending out of the charging box 1 is sufficient for the user to grasp it normally, the cigarette rod 2 will remain 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 chamber through the outlet of the charging chamber. The user needs to apply a little pressure to the cigarette rod 2 so that the pressure and the weight of the cigarette rod 2 itself are greater than the repulsive force between the magnetic parts in the second drive assembly. At this time, the repulsive force between the magnetic parts will be converted into a thrust to make the cigarette rod 2 continue to be placed into the charging chamber, so as to realize the cigarette rod 2 from Figure 4 The second displacement position of the middle cigarette rod 2 is Figure 1 The cigarette rod 2 is displaced at its position, and at this time, the cigarette rod 2 electrode contacts the elastic electrode 15 to achieve 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. The material of the cigarette rod electrode 7 includes iron, nickel, Permalloy, iron-cobalt (FeCo) alloy, iron-aluminum alloy, and ferromagnetic material with surface electroplated with silver or gold.

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

[0065] Example 2

[0066] like Figure 5-8 As shown, this embodiment provides an electromagnetic ejection heating cigarette device, which is different from the embodiment 1 in that the first driving assembly 3 includes an electromagnet unit, a moving iron core 13, at least two insulating brackets 17 and at least two elastic electrodes 15;

[0067] Exemplarily, the moving iron core 13 has a T-shaped structure, and the bottom end of the moving iron core 13 is connected to the electromagnet unit; the insulating bracket 17 is arranged through the top of the moving iron core 13; the insulating bracket 17 is provided with a second through hole 19, and the elastic electrode 15 is arranged in the second through hole 19 and passes through the top of the moving iron core 13; wherein, at least two elastic electrodes 15 are electrically connected to the integrated circuit board 4 and the cigarette rod electrode 7 respectively.

[0068] Specifically, the insulating bracket 17 is made of insulating material and fastens the elastic electrode 15 through the second through hole 19 .

[0069] In this embodiment, when the user needs to take out the cigarette rod 2, by triggering the button 21 on the charging box 1, the button board 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 direction of the power supply current to the electromagnet unit, changes the current direction of the coil 12 to the moving iron core 13, so that the coil 12 produces an opposite magnetic direction, drives the moving iron core 13 to drive the first end 26 of the cigarette rod 2 to move one end distance toward the direction of the charging chamber opening 6, and realizes the first level displacement of the cigarette rod 2, such as Figure 7 The middle cigarette rod 2 is at the first displacement position; at this time, the second magnetic member 9 originally located below the first magnetic member 8 is pushed to the positive side of the first magnetic member 8, and the repulsive force between the two magnetic members reaches the maximum, and the repulsive force drives the first end 26 of the cigarette rod 2 to continue to move toward the charging chamber opening 6 until the length of the cigarette rod 2 extending out of the charging box 1 is enough for the user to grab it normally, thereby realizing the second displacement of the cigarette rod 2. Figure 8 At the second displacement position of the middle 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 is displaced in the opposite direction and reset to attract 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 chamber through the outlet of the charging chamber. The user needs to apply a little pressure to the cigarette rod 2 so that the pressure and the weight of the cigarette rod 2 itself are greater than the repulsive force between the magnetic parts in the second drive assembly. At this time, the repulsive force between the magnetic parts will be converted into a thrust to make the cigarette rod 2 continue to be placed into the charging chamber, so as to realize the cigarette rod 2 from Figure 8 The second stage displacement position of the cigarette rod 2 is Figure 5The cigarette rod 2 is displaced at its position. At this time, the cigarette rod electrode 7 contacts the elastic electrode 15. The elastic electrode 15 sends a feedback signal to the integrated circuit board 4, and the cigarette rod battery power is detected by the charging detection module. If it is detected that the cigarette rod 2 is low on power, the cigarette rod battery is charged through the elastic electrode 15, and the current is distributed to the electromagnet unit at the same time, so that the coil 12 generates magnetism, the moving iron core 13 generates magnetic force, and the moving iron core 13 is driven to be tightly adsorbed on the fixed iron core 11, and the moving iron core 13 generates magnetic force to adsorb the cigarette rod electrode 7, ensuring that the elastic electrode 15 is fully compressed so that the elastic electrode 15 and the cigarette rod electrode 7 are in reliable contact, so that the charging box 1 can stably charge 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 remains unchanged, but the current supplying power to the electromagnet is reduced to only maintain the adsorption of the cigarette rod 2 to ensure that the static power consumption of the product is not too large.

[0072] In summary, this embodiment realizes the automatic and smooth displacement of the cigarette rod 2 when it is taken out by setting two levels of driving force, namely, the first driving component 3 driving and the second driving component driving. The first driving component 3 initially pushes the cigarette rod 2 to move in the direction of the charging chamber opening 6 to realize the first level displacement of the cigarette rod 2, and then through the second driving component, the repulsive force between the magnetic parts is used to make the cigarette rod 2 perform the second level displacement until the length of the part extending out of the charging chamber is sufficient for the user to grab normally, which significantly optimizes the convenience and comfort of the user when taking the cigarette rod 2 and improves the overall user experience. In this embodiment, after the cigarette rod 2 is taken out, the electromagnet unit can intelligently convert the signal and drive the electromagnet moving iron core 13 to move in the reverse direction to the reset position, thereby realizing the automatic reset function of the cigarette rod 2 and effectively reducing the user's operation steps. In this embodiment, by setting the repulsive force between the magnetic parts in the second driving component to be greater than the weight of the cigarette rod 2 itself, it is ensured that the cigarette rod 2 can also be stably suspended in a specific position when it is not taken out in time, avoiding the problem of falling due to gravity, and further improving the safety and stability of the device.

Therefore, the breadth and scope of the claims should not be limited to the exemplary embodiments described above.
