Electronic atomizing device

Abstract

The electronic atomizer (100) includes a substrate (10) having a heating cavity (11) formed therein, and an electrode assembly (30) including a first electrode (32) and a second electrode (34), both of which are at least partially inserted into the heating cavity (11). The electrode assembly (30) is controllable to form an arc between the first and second electrodes within the heating cavity to generate plasma, and the polarity of the first and second electrodes is switched between positive and negative at a predetermined interval. The first and second electrodes alternately function as cathodes, preventing one electrode from being burned out due to its long-term role as a cathode. The alternating cathode between the first and second electrodes results in a more uniform temperature distribution throughout the substrate after several switchings, allowing the substrate to more uniformly heat and atomize the aerosol-generating substrate. This improves the spatial uniformity of plasma heating and reduces electrode damage.

[0001] [Cross - reference to Related Applications] This application claims the priority of Chinese Patent Application No. 202223171651.6, entitled "Electronic Atomization Device", filed on November 28, 2022, and all of its contents are incorporated herein by reference.

[0002] This application relates to the technical field of atomization, and particularly to electronic atomization devices.

Background Art

[0003] An aerosol is a colloidal dispersion system formed by solid or liquid microparticles dispersed and floating in a gas medium. Since the aerosol is inhaled into the human body through the respiratory system, it provides a new alternative inhalation method for users. For example, atomization devices that bake and heat an aerosol - generating substrate of herbs or pastes to generate an aerosol can be applied in different fields to supply an inhalable aerosol to users, replacing the normal product form and inhalation method.

[0004] Generally, an aerosol - generating substrate is heated by an electronic atomization device, and some electronic atomization devices use a plasma heating method. Specifically, the plasma heating method arranges a high - voltage electrode and a low - voltage electrode at a certain interval in a heating body respectively. When a high voltage is applied between the electrodes, an arc and plasma are generated in the gap, and heating is performed by utilizing the thermal energy of the plasma.

[0005] However, when discharging with a DC high-voltage power supply, the plasma within the discharge gap exhibits a temperature gradient from the high-voltage electrode to the low-voltage electrode. As a result, the heating element shows a gradual temperature change in the axial direction, impairing the spatial uniformity of heating. Furthermore, because the cathode is subjected to impact from positive ions in the plasma, the cathode temperature becomes significantly higher than that of the anode. While selecting high-temperature resistant electrode materials can mitigate electrode burnout to some extent, discharge failures due to electrode damage are still likely to occur. Therefore, conventional plasma heating methods suffer from poor spatial uniformity of heating and are prone to electrode damage. [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] Based on this, there is a need to provide an electron atomizing device to address the problems of low spatial uniformity and fragile electrodes in plasma heating methods. [Means for solving the problem]

[0007] The electronic atomizing device is A substrate in which a heating cavity is formed inside, An electrode assembly comprising a first electrode and a second electrode, wherein at least a portion of each of the first and second electrodes is inserted into the heating cavity, The heating cavity can be controlled to form an arc between the first electrode and the second electrode to generate plasma, and the polarity of the first electrode and the second electrode can be switched at a predetermined period.

[0008] In the above-described electron atomizing device, the heating cavity is controlled to generate plasma by forming an arc between the first electrode and the second electrode. The plasma generated by the discharge between the first electrode and the second electrode heats the substrate, and further heats and atomizes the aerosol generating substrate provided on the substrate, thereby generating an aerosol that the user can inhale.

[0009] Furthermore, the anode and anode polarity of the first and second electrodes are switched at predetermined intervals. That is, within a certain period, the first electrode is the cathode and the second electrode is the anode, and within another certain period, they are switched in the opposite direction, with the first electrode being the anode and the second electrode being the cathode. By switching in the opposite direction in this way, the first and second electrodes alternately function as cathodes, preventing one of them from being burnt out at high temperatures for an extended period and preventing discharge failure due to electrode damage. In addition, by alternately switching the anode and anode polarity of the first and second electrodes, the cathode, which tends to get hotter, alternates between the first and second electrodes. Moreover, one end of the substrate becomes hotter at one end during a certain period, and the other end becomes hotter at another period. After several switching cycles, the temperature spatial distribution of the entire substrate becomes more uniform, allowing the substrate to heat and atomize the aerosol generating substrate more uniformly. As a result, the spatial uniformity of heating by plasma heating is improved, and the electrodes become less prone to damage.

[0027] As shown in Figure 1, in one embodiment of the present invention, an electron atomizer 100 is provided, which includes a substrate 10 and an electrode assembly 30, wherein a heating cavity 11 is formed in the substrate 10, and the electrode assembly 30 includes a first electrode 32 and a second electrode 34, both of which are inserted at least partially into the heating cavity 11. Plasma can be generated in the heating cavity 11 by controlling the formation of an arc between the first electrode 32 and the second electrode 34, thereby heating the substrate 10 with the plasma generated by the discharge between the first electrode 32 and the second electrode 34, and further heating and atomizing the aerosol generating substrate provided in the substrate 10 to generate an aerosol for the user to inhale.

[0028] Furthermore, the anode and anode polarity of the first electrode 32 and the second electrode 34 are switched at a predetermined cycle. That is, within a certain period, the first electrode 32 is the cathode and the second electrode 34 is the anode, and within another certain period, they are switched in the opposite direction, with the first electrode 32 being the anode and the second electrode 34 being the cathode. By switching in the opposite direction in this way, the first electrode 32 and the second electrode 34 alternately function as cathodes, preventing one of them from being burnt out at high temperatures for a long period of time and preventing discharge failure due to electrode damage. In addition, by alternately switching the anode and anode polarity of the first electrode 32 and the second electrode 34, the cathode, which tends to get hotter, alternates between the first electrode 32 and the second electrode 34. Moreover, one end of the substrate 10 becomes hot for a certain period, and the other end becomes hot for another period. After several switching cycles, the temperature spatial distribution of the entire substrate 10 becomes more uniform, thereby enabling the substrate 10 to heat and atomize the aerosol generating substrate more uniformly. This results in better spatial uniformity of heating through plasma heating, and makes the electrodes less prone to damage.

[0029] As shown in Figure 2, the electron atomizer 100 further includes a power supply assembly 50 and a control assembly 70. The control assembly 70 is electrically connected between the power supply assembly 50 and the electrode assembly 30. The power supply assembly 50 supplies a high-voltage alternating current, and the control assembly 70 outputs a high-voltage direct current to the electrode assembly 30 and is configured to switch the anode and yin-yang polarity of the first electrode 32 and the second electrode 34 at a predetermined period. By electrically connecting the control assembly 70 between the power supply assembly 50 and the electrode assembly 30 in this way, the control assembly 70 can convert the high-voltage alternating current into a high-voltage direct current flowing through the electrode assembly 30, and the control assembly 70 can switch the anode and yin-yang polarity at a predetermined period, thereby periodically changing the polarity of the first electrode 32 and the second electrode 34. The switching time during periodic switching may be set to the same time, or to different times as needed. By controlling the time ratio in which the first electrode 32 or the second electrode 34 is the cathode, the high-temperature region is controlled to move between the first electrode 32 and the second electrode 34.

[0030] Specifically, the power supply assembly 50 includes a power module 52 and a transformer 54, the transformer 54 being connected to the power module 52 and outputting a high-voltage alternating current, and the transformer 54 increasing the voltage of the current. The control assembly 70 includes a rectifier 72 and a switching control member 74, the rectifier 72 being electrically connected between the transformer 54 and the switching control member 74 and converting the high-voltage alternating current into a high-voltage direct current flowing to the switching control member 74, the first electrode 32 and the second electrode 34 both being electrically connected to the switching control member 74, and the switching control member 74 switching the anode and yin polarity of the first electrode 32 and the second electrode 34 in opposite directions at a predetermined period. In this way, the rectifier 72 converts the high-voltage AC current output from the transformer 54 into a high-voltage DC current, and then the switching control member 74 outputs the high-voltage DC current to the electrode assembly 30. The switching control member 74 periodically switches the polarity of the first electrode 32 and the second electrode 34, so that the first electrode 32 and the second electrode 34 alternately function as cathodes, preventing the first electrode 32 or the second electrode 34 from burning out at high temperatures as a cathode for a long period of time, and constantly switching the high-temperature region in the substrate 10 corresponding to the cathode, resulting in more uniform heat generation throughout the substrate 10.

[0031] As shown in Figure 1, in some embodiments, the substrate 10 is configured as a central heating structure inserted into the aerosol generating substrate. When plasma is generated in the heating cavity 11 inside the substrate 10, the substrate 10 itself is heated, and the substrate 10 is inserted into the aerosol generating substrate, conducting heat from inside the aerosol generating substrate to heat and atomize it.

[0032] Furthermore, the base body 10 includes a tube 14, the tube 14 having a heating cavity 11, and both the first electrode 32 and the second electrode 34 are inserted at least partially into the heating cavity 11, with their ends spaced apart in the axial direction of the tube 14. In this way, an arc is formed inside the tube 14 along the axial direction of the tube 14, and the tube 14 is heated along the axial direction of the tube 14. When in use, when an aerosol generating substrate is inserted into the tube 14, the tube 14 can heat the aerosol generating substrate from the inside out.

[0033] Specifically, the tube 14 has an opposing top end 141 and bottom end along its axial direction. The initial polarity of one of the first electrode 32 and second electrode 34 whose axial end is located at the top end 141 is cathode, and the initial polarity of the other of the first electrode 32 and second electrode 34 whose axial end is located at the bottom end 143 is anode. This positions the cathode, which has a higher temperature, at the top end 141, bringing the high-temperature region closer to the top end 141 and improving the smoke emission rate at startup.

[0034] Specifically, in this embodiment, the tube 14 includes an inner tube 145 and an outer tube 147 fitted outside the inner tube 145 at a distance from it, and the heating cavity 11 includes a first subcavity 112 and a second subcavity 114 that communicate with each other, the first subcavity 112 is formed through the inner tube 145 along its axial direction, and the second subcavity 114 is partitioned between the top of the inner tube 145 and the outer tube 147. At least a portion of one of the first electrode 32 and the second electrode 34 is inserted into the first subcavity 112, and at least a portion of the other of the first electrode 32 and the second electrode 34 is inserted into the second subcavity 114. In this manner, a heating cavity 11 is formed by fitting the inner tube 145 and the outer tube 147 together, and the first electrode 32 and the second electrode 34 are positioned spaced apart along the axial direction of the inner tube 145. Then, the system is controlled to generate plasma in at least the first subcavity 112 along the axial direction of the inner tube 145, thereby heating the tube 14 along the axial direction.

[0035] Furthermore, the first electrode 32 is connected to the circuit by having one end inserted into the first subcavity 112 and the other end located outside the first subcavity 112. The second electrode 34 includes a main body 341 and a lead portion 343. The main body 341 is provided inside the second subcavity 114 and is positioned opposite the first electrode 32 at a distance along the axial direction of the inner tube 145. The lead portion 343 is connected to the main body 341 and extends to the outside through the gap between the inner tube 145 and the outer tube 147, connecting the second electrode 34 to the circuit. The main bodies 341 of the first electrode 32 and the second electrode 34 heat the tube 14 by generating an arc in the axial direction within the first subcavity 112.

[0036] As shown in Figures 3 and 4, in some other embodiments, the substrate 10 is configured as an outer peripheral heating structure surrounding the aerosol generating substrate. That is, the substrate 10 surrounds the aerosol generating substrate, and when plasma is generated in the heating cavity 11, the substrate 10 is heated, and the substrate 10 heats the aerosol generating substrate surrounded by it from the outside in, and further atomizes it to form an aerosol that the user inhales.

[0037] Furthermore, the base body 10 includes a housing 16 and an inner cylinder 18 fitted into the housing 16. The inner cylinder 18 has a housing cavity 13, and a heating cavity 11 is partitioned between the inner cylinder 18 and the housing 16. The first electrode 32 and the second electrode 34 are both attached to the housing 16, and at least a portion of both are inserted into the heating cavity 11 between the inner cylinder 18 and the housing 16. Thereafter, a discharge occurs in the heating cavity 11 to generate an arc and plasma, which heats the inner cylinder 18, and further heats and atomizes the aerosol generating substrate in the housing cavity 13 of the inner cylinder 18.

[0038] Specifically, one of the first electrode 32 and the second electrode 34 is provided so as to surround the outer circumference of the inner cylinder 18, and the other of the first electrode 32 and the second electrode 34 is located at the center of the bottom of the inner cylinder 18. In this way, the arc formed between the first electrode 32 and the second electrode 34 rotates around the entire outer circumference of the inner cylinder 18 by the drive of the magnetic field, heating the entire outer circumference of the inner cylinder 18 and making the heating area more uniform. Preferably, the second electrode 34 has a discharge ring fitted to the outer circumference of the inner cylinder 18, and the electron atomizer 100 further includes a magnetic ring 80 provided in the housing 16 and fitted to the outer circumference of the discharge ring, and the magnetic ring 80 is used to drive the arc and rotate it around the circumferential direction of the discharge ring in the heating cavity 11, uniformly heating the inner cylinder 18 from the entire outer circumference.

[0039] Furthermore, the initial polarity of one of the first electrode 32 and second electrode 34, located at the center of the bottom of the inner cylinder 18, is cathode, while the initial polarity of the other of the first electrode 32 and second electrode 34, which surrounds the outer circumference of the inner cylinder 18, is positive. In this way, the temperature at the center of the bottom of the inner cylinder 18 is increased in the initial state, the bottom of the inner cylinder 18 is heated rapidly, the smoke generation time is shortened in the initial stage, and the smoke generation rate at the start of atomization is improved. After the requirement for rapid smoke generation is met, the polarities of the first electrode 32 and second electrode 34 are switched in the opposite direction, with one side at the outer circumference of the inner cylinder 18 becoming cathode and the other side at the center of the bottom of the inner cylinder 18 becoming anode. As a result, the temperature field at the outer circumference of the inner cylinder 18 is relatively uniform, and the aerosol generation substrate can be uniformly heated and atomized.

[0040] To make it clear, the polarity of the first electrode 32 and the second electrode 34 may be switched in a single step, or it may be switched periodically multiple times; it is not limited to this.

[0041] Preferably, the inner cylinder 18 is detachably provided in the housing 16. When heating and atomizing the aerosol generating substrate, the aerosol generating substrate is placed in the housing cavity 13 of the inner cylinder 18, and the inner cylinder 18 is attached to the housing 16. This creates a heating cavity 11 between the inner cylinder 18 and the housing 16. The electrode assembly 30 discharges within the heating cavity 11 to generate an arc and plasma, and the heat from the plasma further heats the inner cylinder 18 and the aerosol generating substrate inside the inner cylinder 18. After using the electronic atomizer 100 for a certain period of time, the inner cylinder 18 can be easily removed from the housing 16 for cleaning. This prevents residue inside the inner cylinder 18 from affecting the atomization suction feel after prolonged use, thus ensuring a good atomization suction feel.

[0042] Each of the technical features in the above embodiments can be combined in any way, and for the sake of brevity, not all possible combinations of each of the technical features in the embodiments described above have been described. However, as long as these combinations of technical features are inconsistent, they should be considered to fall within the scope described herein.

[0043] The above embodiments describe only a few embodiments of the present application, and while these descriptions are specific and detailed, they should not be interpreted as limiting the scope of the patent of this application. Furthermore, a person skilled in the art can make various modifications and improvements as long as they do not deviate from the spirit of this application, and these modifications and improvements fall within the scope of protection of this application. Therefore, the scope of protection of the patent of this application should be based on the attached claims. [Explanation of Symbols]
