Description

[Technical Field]

[0001] The present application relates to the technical field of electronic atomization, and in particular to atomizers and electronic atomization devices. [Background technology]

[0002] Aerosols are colloidal dispersions formed by dispersing and suspending fine particles of solid or liquid in a gas medium, and because aerosols are inhaled into the human body through the respiratory system, they provide users with a new alternative inhalation method. For example, atomization devices that generate aerosols by baking and heating aerosol-generating substrates such as herbs or pastes can be applied in various fields and provide users with inhalable aerosols, thereby replacing conventional product forms and inhalation methods.

[0003] Electronic atomizers typically heat the aerosol-generating substrate using resistance or electromagnetic induction, but both of these heating methods require long preheating times, resulting in poor user convenience. Resistance heating involves energizing a resistive element with an external power source, which then transfers heat to the aerosol-generating substrate via thermal conduction. However, heat conduction takes time and hysteresis exists, resulting in overheating and scorching of the aerosol-generating substrate near the resistive element, which can adversely affect the uniformity of the inhalation sensation. Furthermore, when the resistive heating element comes into contact with the aerosol-generating substrate and heats it, metal materials in the resistive heating element may enter the aerosol formed by atomizing the aerosol-generating substrate, potentially affecting the inhalation sensation of the atomized aerosol.

[0004] Therefore, the conventional method of heating the aerosol generating substrate requires a long preheating time and the atomized liquid does not feel good when inhaled. Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, there is a need to provide an atomizer and an electronic atomizer that address the problems of the long preheating time of the conventional electronic atomizer and the poor atomization sensation. [Means for solving the problem]

[0006] The atomizer is a heating element having a heating cavity formed therein; at least one set of electrode assemblies, each set of the electrode assemblies including a first electrode and a second electrode, both of which are inserted into the heating cavity, and in which a controlled arc is formed between the first electrode and the second electrode to form a plasma; The heating element may define a receiving area for receiving an aerosol-generating substrate.

[0007] In the atomizer, both the first and second electrodes are inserted into the heating cavity of the heating element, and a dielectric breakdown occurs between the first and second electrodes of AC or DC power supply, generating an arc. This ionizes the gas in the heating cavity to form plasma, which heats the heating cavity. The heating element can also form a storage space for the aerosol-generating substrate, and the storage space can conduct heat between the heating element and the heating cavity. After the interior of the heating cavity is heated by the plasma, the heat is transferred to the storage space, which further heats the aerosol-generating substrate installed in the storage space. In this way, the heat generated by the plasma in the heating cavity can be used to quickly heat the aerosol-generating substrate, shortening the pre-heating wait time and improving user convenience. This also prevents the aerosol-generating substrate from being burned due to excessive pre-heating time, improving the inhalation sensation of atomization. At the same time, during the heating process, metal components such as electrodes do not need to come into direct contact with the aerosol-generating substrate, which prevents metal substances from being mixed into the aerosol after the aerosol-generating substrate is atomized, further improving the inhalation sensation of the atomization.

[0016] In one embodiment, the heating base is molded separately from the mounting base, and after the heating base and the mounting base are fixedly connected, a thermally conductive cavity is defined between them, and a thermally conductive medium is filled in the thermally conductive cavity.

[0017] The electronic atomization device includes the atomizer.

[0018] In one embodiment, the electronic atomization device further includes a housing, the atomizer is disposed within the housing, and an intake passage is formed within the housing through which air flows around the outer periphery of the heating element and enters the accommodation portion.

The terms "vertical," "horizontal," "top," "bottom," "left," "right," and similar terms used herein are for illustrative purposes only and do not represent the only embodiment.

[0028] As shown in FIG. 1, one embodiment of the present application provides an atomizer 100, which heats an aerosol-generating substrate by plasma heating. By utilizing the high energy density of plasma heating, the atomizer 100 can achieve instantaneous rapid heating and atomization, effectively shortening the preheating time and preventing scorching caused by excessively long preheating times, thereby improving the inhalation sensation of atomization.

[0029] The atomizer 100 includes a heating element 10 and at least one electrode assembly 30. A heating cavity 11 is formed within the heating element 10. Each electrode assembly 30 includes a first electrode 32 and a second electrode 34. Both the first electrode 32 and the second electrode 34 are inserted into the heating cavity 11, and a controlled arc is formed between the first electrode 32 and the second electrode 34 within the heating cavity 11 to generate plasma. That is, both the first electrode 32 and the second electrode 34 are inserted into the heating cavity 11 of the heating element 10, and a dielectric breakdown occurs between the first electrode 32 and the second electrode 34, which are supplied with AC or DC, to generate an arc. This further ionizes gas within the heating cavity 11 to form plasma, which then heats the heating cavity 11. The heating element 10 may also have a receiving portion 15 for receiving an aerosol-generating substrate, and the receiving portion 15 is capable of thermal conduction between the receiving portion 15 and the heating cavity 11. After the inside of the heating cavity 11 is heated by the plasma, the heat is transferred to the accommodation location 15 and can further heat the aerosol-generating substrate provided in the accommodation location 15 .

[0030] In this way, the aerosol-generating substrate is quickly heated using the heat generated by the plasma in the heating cavity 11, and the high energy density of plasma heating is utilized to shorten the preheating waiting time, increasing user convenience and preventing the aerosol-generating substrate from being burned due to excessive preheating time, thereby improving the inhalation feel of the atomized substance. At the same time, since metal components such as electrodes do not need to come into direct contact with the aerosol-generating substrate during the heating process, this prevents metal substances from being mixed into the aerosol after the aerosol-generating substrate is atomized, further improving the inhalation feel of the atomized substance.

[0031] In some embodiments, the first electrode 32 and the second electrode 34 in each electrode assembly 30 are both made of one of tungsten alloy, carbon fiber, and copper alloy, the diameters of the first electrode 32 and the second electrode 34 are in the range of 0.4 to 1.0 mm, and the distance between the first electrode 32 and the second electrode 34 is 5 to 10 mm.

[0032] 1, the number of electrode assemblies 30 is preferably one set, and as shown in Fig. 2, the number of electrode assemblies 30 is preferably multiple sets, and the multiple sets of electrode assemblies 30 may be discharged simultaneously in parallel, or the multiple sets of electrode assemblies 30 may be discharged sequentially. In addition, in the heating member 10, all of the first electrodes 32 and all of the second electrodes 34 are distributed symmetrically with respect to a certain symmetry reference so as to form a uniform temperature field in the heating cavity 11.

[0033] In some embodiments, the heating cavity 11 is filled with an inert gas, and after an arc is generated by dielectric breakdown between the first electrode 32 and the second electrode 34 in the heating cavity 11, the inert gas filled in the heating cavity 11 is ionized to form plasma, thereby generating heat. The generated heat is efficiently transferred to the accommodation portion 15 via the inert gas, thereby improving heat transfer efficiency. For example, the heating cavity 11 may be filled with a gas such as helium gas, neon gas, or argon gas. Note that in some other embodiments, the heating cavity 11 may be filled with air; this is not a limitation.

[0034] In some embodiments, the air pressure inside the heating cavity 11 is lower than standard atmospheric pressure. Maintaining the pressure inside the heating cavity 11 at a low level prevents excessive pressure from being applied to the cavity wall of the heating cavity 11 (i.e., the heating element 10), and allows the thickness and strength of the heating element 10 to be reduced, thereby further improving heat transfer efficiency. For example, the air pressure inside the heating cavity 11 is 1 / 5 atmosphere to 1 atmosphere, and preferably, the air pressure inside the heating cavity 11 is 1 / 5 atmosphere to 1 / 3 atmosphere. Note that in some other embodiments, the air pressure inside the heating cavity 11 may be set to standard atmospheric pressure, and is not limited thereto.

[0035] Preferably, the heating element 10 is made of any one of quartz glass, silicon carbide, silicon nitride, zirconia, and alumina, and thus the heating element 10 has good insulation properties to prevent electrical leakage when ionizing gas inside the heating element 10, and the heating element 10 has good thermal conductivity so that heat generated by ionizing gas inside the heating cavity 11 is easily transferred through the heating element 10 to the accommodation location 15. In addition, the thickness of the heating element 10 is preferably 0.4 to 1.0 mm, which not only satisfies the strength requirement but also enables efficient heat transfer.

[0036] 1 and 2, in some embodiments, a portion of the outer surface of the heating element 10 is recessed inward to form a first accommodating cavity with one open end, and the heating cavity 11 is provided around the outer periphery of the first accommodating cavity, which is configured as an accommodating portion 15. That is, a portion of the outer surface of the heating element 10 is recessed inward to form the first accommodating cavity, and the heating cavity 11 is provided around the outer periphery of the first accommodating cavity, so that heat generated in the heating cavity 11 can be transferred to various positions around the outer periphery of the first accommodating cavity, thereby enabling the aerosol-generating substrate in the first accommodating cavity to be heated uniformly and quickly.

[0037] Furthermore, the heating cavity 11 includes a first sub-cavity 112 and a second sub-cavity 114. The first sub-cavity 112 is annularly disposed around the outer periphery of the first accommodating cavity, and the second sub-cavity 114 is located at the bottom of the first accommodating cavity opposite its own opening and communicates with the first sub-cavity 112. That is, the first sub-cavity 112 surrounds the outer periphery of the first accommodating cavity, and the second sub-cavity 114 is located at the bottom of the first accommodating cavity. The heating cavity 11 formed by the communication between the first sub-cavity 112 and the second sub-cavity 114 completely surrounds the outer periphery of the first accommodating cavity and uniformly transfers heat from all directions to the first heating cavity 11.

[0038] An electrode assembly 30 is inserted into at least one of the first subcavity 112 and the second subcavity 114. That is, the electrode assembly 30 may be configured to be inserted into the first subcavity 112, or the electrode assembly 30 may be configured to be inserted into the second subcavity, or multiple sets of electrode assemblies 30 may be provided, each configured to be inserted into both the first subcavity 112 and the second subcavity. The electrode assembly 30 generates an arc to ionize the gas in the heating cavity 11, forming plasma and generating heat. For example, if the electrode assembly 30 is inserted only into the first subcavity 112, the heat generated by the electrode assembly 30 ionizing the gas can flow to the second subcavity 114 and heat the aerosol-generating substrate in the storage location 15 via the first subcavity 112 and the second subcavity 114. Similarly, when the electrode assembly 30 is inserted only into the second subcavity 114, the heat generated in the second subcavity 114 can still be transferred into the first subcavity 112, and similarly heat the aerosol-generating substrate in the storage location 15 via the first subcavity 112 and the second subcavity 114.

[0039] In addition, in some other embodiments, the heating cavity 11 may include only one of the first sub-cavity 112 and the second sub-cavity 114, and may transfer heat therein to the adjacent accommodating portion 15, and is not limited thereto.

[0040] 3 , in another embodiment, the heating element 10 includes a mounting base 12 and a heating base 14 provided on the mounting base 12, and the heating cavity 11 includes a third sub-cavity 116 and a fourth sub-cavity 118, the third sub-cavity 116 is formed inside the mounting base 12, and the fourth sub-cavity 118 is formed inside the heating base 14 and communicates with the third sub-cavity 116, the electrode assembly 30 is inserted into the third sub-cavity 116, and a receiving space 15 surrounding the heating base 14 is configured between the opposing outer surfaces of the mounting base 12 and the heating base 14. Preferably, the heating base 14 is elongated, and the fourth sub-cavity 118 extends inside the heating base 14 along the axial direction of the heating base 14 and communicates with the third sub-cavity 116.

[0041] That is, the heating base 14 is configured as a heating needle, and a storage space 15 for storing an aerosol-generating substrate is defined between the heating base 14 and the mounting base 12. When using the atomizer 100, the aerosol-generating substrate is inserted into the heating base 14, and the aerosol-generating substrate is stored and fixed in the space between the opposing outer surfaces of the heating base 14 and the mounting base 12 (i.e., the storage space 15). Furthermore, a third sub-cavity 116 is formed within the mounting base 12, and a fourth sub-cavity 118 communicating with the third sub-cavity 116 is formed within the heating base 14. The electrode assembly 30 is inserted into the third sub-cavity 116, and when the gas is ionized by an arc formed by dielectric breakdown between the first electrode 32 and the second electrode 34 within the third sub-cavity 116, plasma is formed within the third sub-cavity 116, generating heat. The generated heat can also flow from the third sub-cavity 116 to the fourth sub-cavity 118, causing the heating base 14 to generate heat and thereby heating the aerosol-generating substrate.

[0042] 4 and 5, in yet another embodiment, the heating element 10 includes a mounting base 12 and a heating base 14 provided on the mounting base 12, a heating cavity 11 formed inside the mounting base 12, and a second accommodating cavity with one open end formed inside the heating base 14, the heating cavity 11 being located at the bottom opposite the opening of the second accommodating cavity, and the second accommodating cavity being configured as an accommodating portion 15. That is, the heating cavity 11 is formed inside the mounting base 12 of the heating element 10, and heat is generated in the heating cavity 11 by the first electrode 32 and the second electrode 34. The generated heat is transferred to the accommodating portion 15, which is the second accommodating cavity of the heating base 14 at the top, and heats the aerosol-generating substrate in the accommodating portion 15.

[0043] As shown in Fig. 4, the heating base 14 and the mounting base 12 are preferably molded as a single unit to simplify the device. As shown in Fig. 5, the heating base 14 is preferably molded separately from the mounting base 12, and the heating base 14 and the mounting base 12 may be manufactured as standardized components, which makes it easier to manufacture the atomizer 100 as a standard component and improves the versatility of the atomizer 100.

[0044] 5, the heating base 14 is molded separately from the mounting base 12. After the heating base 14 and the mounting base 12 are fixedly connected, a heat conduction cavity 50 is defined between them, and a heat conduction medium is filled into the heat conduction cavity 50, thereby efficiently transferring heat generated inside the mounting base 12 to the receiving portion 15 of the heating base 14 through the heat conduction medium, thereby ensuring heat conduction performance. The heat conduction medium is a phase-change interface heat conduction medium, such as toluene, water, naphthalene, dowsam, or aluminum bromide, and has good heat exchange efficiency.

[0045] As shown in FIG. 6, an embodiment of the present invention further provides an electronic atomization device 200, which includes the above-mentioned atomizer 100, has a short pre-heating waiting time, and provides a good atomization sensation.

[0046] In some embodiments, the electronic atomization device 200 further includes a housing 210, in which the atomizer 100 is disposed. The housing 210 defines an air intake passage 211 through which air flows around the heating element 10 and enters the receiving area 15. When a user inhales on the electronic atomization device 200, external air enters the housing 210, first flows around the heating element 10, removing heat from the outer surface of the heating element 10 and increasing the temperature of the airflow itself, before entering the receiving area 15, where it mixes with the atomized aerosol. Finally, the airflow carries the aerosol and flows into the user's mouth, where it is inhaled. The air intake passage 211 guides the airflow through the heating element 10 and then enters the receiving area 15. This allows the airflow to cool the outer surface of the heating element 10 while preheating the airflow entering the receiving area 15, improving the atomization effect.

[0047] Specifically, the heating element 10 includes a mounting base 12 and a heating base 14 provided on the mounting base 12, the heating cavity 11 includes a third sub-cavity 116 and a fourth sub-cavity 118, the third sub-cavity 116 is formed inside the mounting base 12, the fourth sub-cavity 118 is formed inside the heating base 14 and communicates with the third sub-cavity 116, an electrode assembly 30 is inserted into the third sub-cavity 116, and the opposing outer surfaces of the mounting base 12 and the heating base 14 are configured as an accommodating portion 15 that surrounds the heating base 14. That is, the mounting base 12 of the heating element 10 forms a third sub-cavity 116, and heat is generated within the third sub-cavity 116 by the first electrode 32 and the second electrode 34. The generated heat is transferred into the fourth sub-cavity 118 of the heating base 14, where it heats the aerosol-generating substrate inserted into the heating base 15.

[0048] In addition, the intake passage 211 is configured to flow around the outer periphery of the mounting base 12 before flowing into the accommodating portion 15. In this way, the intake passage 211 first flows around the outer periphery where the third sub-cavity 116 is formed, thereby allowing the airflow to exchange heat with the outer surface of the mounting base 12 before entering the accommodating portion 15 of the heating base 14.

[0049] In addition, in some other embodiments, the intake passage 211 may not flow through the mounting base 12 but may enter the accommodating location 15 directly from the outside, thereby simplifying the structure of the intake passage, and the configuration of the intake passage 211 is not limited here.

[0050] The technical features of the above-described embodiments may be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features of the above-described embodiments are described, but all such combinations should be considered to fall within the scope described in this specification.

[0051] The above examples only describe some embodiments of the present application, and although the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent of the present application. It should be noted that those skilled in the art can make some modifications or improvements without departing from the concept of the present application, and both of these modifications and improvements belong to the scope of protection of the present application. Therefore, the scope of protection of the patent of the present application should be based on the scope of the attached claims. [Explanation of symbols]
