Description

Technical Field

[0001] The present application relates to the field of electronic atomization technology, and in particular to an atomizer and an electronic atomization device. Background Art

[0002] Aerosol is a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium. Since aerosol can be absorbed by the human body through the respiratory system, it provides users with a new alternative absorption method. For example, an aerosol-generating matrix of herbal or ointment aerosol can be baked and heated to produce an aerosol. This atomizing device can be used in different fields to deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0003] Electronic atomization devices usually use resistance or electromagnetic induction to heat the aerosol generating matrix, but the preheating waiting time required for the above two heating methods is relatively long, which is not convenient for users. In addition, resistance heating is to energize the resistance element to generate heat through an external power supply, and the heated resistance element then transfers the heat to the aerosol generating matrix through heat conduction. Heat conduction takes time and has hysteresis, so it will cause the aerosol generating matrix close to the resistance element to be overburned or even burnt. High temperature overburning or burning will lead to poor taste consistency. Moreover, when the resistance heating element contacts and heats the aerosol generating matrix, the metal substance in the resistance heating element may enter the aerosol formed by the atomization of the aerosol generating matrix, affecting the atomized taste.

[0004] Therefore, the traditional method of heating the aerosol to generate the matrix has a long preheating time and a poor atomization taste. Summary of the invention

[0005] Based on this, it is necessary to provide an atomizer and an electronic atomizer device to address the problems of long preheating waiting time and poor atomization taste of traditional electronic atomizer devices.

[0010] In the above-mentioned atomizer, the first electrode and the second electrode are both extended into the heating chamber of the heating element, and an arc is generated by breakdown between the first electrode and the second electrode of the AC power supply or the DC power supply, and then the gas is ionized in the heating chamber to form a plasma, and the plasma causes the heating chamber to heat up. In addition, the heating element can form a receiving position for accommodating the aerosol generating matrix, and the receiving position can be heat-conducted with the heating chamber. After the heating chamber is heated under the action of the plasma, the heat can be transferred to the receiving position, and then the aerosol generating matrix arranged on the receiving position is heated. In this way, the heat generated by the plasma in the heating chamber is used to quickly heat the aerosol generating matrix, shorten the preheating waiting time, facilitate user use, and prevent the preheating time from being too long and burning the aerosol generating matrix, thereby improving the atomization taste. At the same time, during the heating process, metal parts such as electrodes do not need to directly contact the aerosol generating matrix, which can prevent the aerosol generating matrix from being doped with metal substances after atomization, further improving the atomization taste.

[0042] See also Figure 1 In one embodiment of the present application, an atomizer 100 is provided. The atomizer 100 heats the aerosol-generating matrix by plasma heating. By utilizing the high energy density of plasma heating, instant rapid heating and atomization can be achieved, thereby effectively shortening the preheating time, preventing the preheating time from being too long and causing burning, and improving the atomization taste.

[0043] The atomizer 100 includes a heating element 10 and at least one group of electrode assemblies 30. A heating chamber 11 is formed inside the heating element 10. Each group of electrode assemblies 30 includes a first electrode 32 and a second electrode 34. The first electrode 32 and the second electrode 34 are both extended into the heating chamber 11. An arc can be controlled to form between the first electrode 32 and the second electrode 34 in the heating chamber 11 and plasma can be generated. This is equivalent to extending the first electrode 32 and the second electrode 34 into the heating chamber 11 of the heating element 10, and an arc is generated by breakdown between the first electrode 32 and the second electrode 34 powered by AC or DC, and then ionizing gas in the heating chamber 11 to form plasma, and the plasma heats the heating chamber 11. In addition, the heating element 10 can form a receiving position 15 for carrying an aerosol generating substrate, and the receiving position 15 can conduct heat with the heating chamber 11. After the heating chamber 11 is heated under the action of plasma, the heat can be transferred to the receiving position 15, thereby heating the aerosol generating substrate disposed on the receiving position 15.

[0044] In this way, the heat generated by the plasma in the heating chamber 11 is used to quickly heat the aerosol-generating matrix, and the high energy density of plasma heating is used to shorten the preheating waiting time, which is convenient for users to use, and prevents the aerosol-generating matrix from being burnt due to the preheating time being too long, thereby improving the atomization taste. At the same time, during the heating process, metal parts such as electrodes do not need to directly contact the aerosol-generating matrix, which can prevent the aerosol-generating matrix from being doped with metal substances after atomization, further improving the atomization taste.

[0045] In some embodiments, the first electrode 32 and the second electrode 34 in each electrode assembly 30 are made of any one of tungsten alloy, carbon fiber and copper alloy, the diameter range of the first electrode 32 and the second electrode 34 is 0.4-1.0 mm, and the spacing between the first electrode 32 and the second electrode 34 is 5-10 mm.

[0046] See also Figure 1 , Optionally, the number of electrode assemblies 30 is set to one group; see Figure 2 Alternatively, the number of electrode assemblies 30 is multiple, and the multiple electrode assemblies 30 can discharge in parallel at the same time, or the multiple electrode assemblies 30 can discharge in sequence. In addition, on the heating element 10, all the first electrodes 32 and all the second electrodes 34 are symmetrically distributed relative to a symmetric reference to form a uniform temperature field in the heating chamber 11.

[0047] In some embodiments, the heating chamber 11 is filled with an inert gas. After the first electrode 32 and the second electrode 34 in the heating chamber 11 are broken down to generate an arc, the inert gas filled in the heating chamber 11 can be ionized to form plasma and generate heat. The generated heat can be efficiently transferred to the accommodating position 15 through the inert gas, thereby improving the heat transfer efficiency. For example, the heating chamber 11 is filled with helium, neon, argon and other gases. It can be understood that in some other embodiments, the heating chamber 11 can also be filled with air, which is not limited here.

[0048] In some embodiments, the air pressure inside the heating chamber 11 is less than the standard atmospheric pressure, so that the pressure inside the heating chamber 11 is maintained at a relatively low level, and no excessive pressure is generated on the cavity wall of the heating chamber 11 (i.e., the heating element 10), thereby reducing the wall thickness and strength of the heating element 10, and further improving the heat transfer efficiency. For example, the air pressure inside the heating chamber 11 is between 1 / 5 of the atmospheric pressure and 1 atmospheric pressure; preferably, the air pressure inside the heating chamber 11 is between 1 / 5 and 1 / 3 of the atmospheric pressure. It is understandable that in some other embodiments, the air pressure inside the heating chamber 11 can also be set to the standard atmospheric pressure, which is not limited here.

[0049] Optionally, the heating element 10 is made of any one of quartz glass, silicon carbide, silicon nitride, zirconium oxide and aluminum oxide, so that the heating element 10 has good insulation, preventing leakage when the gas is ionized inside the heating element 10, and at the same time, the heating element 10 has good thermal conductivity, which facilitates the heat generated by the ionized gas in the heating chamber 11 to pass through the heating element 10 to the accommodating position 15. Optionally, the wall thickness of the heating element 10 is 0.4-1.0 mm, which can meet the strength requirements and conduct heat efficiently.

[0050] See also Figure 1-Figure 2 In some embodiments, part of the outer surface of the heating element 10 is recessed inward to form a first accommodating cavity with one end open, and the heating cavity 11 is arranged around the periphery of the first accommodating cavity; wherein the first accommodating cavity is configured as an accommodating position 15. This is equivalent to that part of the outer surface of the heating element 10 is recessed inward to form the first accommodating cavity, and the heating cavity 11 is arranged outside the first accommodating cavity, so that the heat generated in the heating cavity 11 can be transferred to various positions around the periphery of the first accommodating cavity, and the aerosol generating substrate in the first accommodating cavity can be evenly and quickly heated.

[0051] Furthermore, the heating chamber 11 includes a first sub-cavity 112 and a second sub-cavity 114. The first sub-cavity 112 is arranged in a ring shape around the outer periphery of the first accommodating chamber, and the second sub-cavity 114 is located at the bottom of the first accommodating chamber which is opposite to the opening of the first accommodating chamber, and is connected with the first sub-cavity 112. In other words, the first sub-cavity 112 surrounds the outer periphery of the first accommodating chamber, and the second sub-cavity 114 is arranged at the bottom of the first accommodating chamber. The heating chamber 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 chamber, and heat is evenly transferred to the first heating chamber 11 from all directions.

[0052] Furthermore, the electrode assembly 30 is inserted into at least one of the first sub-cavity 112 and the second sub-cavity 114, which is equivalent to that the electrode assembly 30 can be set to extend into the first sub-cavity 112, or the electrode assembly 30 can be set to extend into the second sub-wall, or multiple groups of electrode assemblies 30 are provided, and the electrode assembly 30 is inserted into both the first sub-cavity 112 and the second sub-wall, so that the gas in the heating cavity 11 is ionized by the electrode assembly 30 to form plasma and heat. For example, the electrode assembly 30 is inserted only into the first sub-cavity 112, and the heat generated by the ionized gas by the electrode assembly 30 can flow to the second sub-cavity 114, and the aerosol generation substrate on the accommodating position 15 can be heated through the first sub-cavity 112 and the second sub-cavity 114. Similarly, if the electrode assembly 30 is inserted only into the second sub-cavity 114 , the heat generated in the second sub-cavity 114 can still be transferred to the first sub-cavity 112 , and the aerosol generating matrix on the accommodating position 15 can also be heated by the first sub-cavity 112 and the second sub-cavity 114 .

[0053] It can be understood that in some other embodiments, the heating chamber 11 includes only any one of the first sub-chamber 112 and the second sub-chamber 114, and can also transfer the heat inside itself to the adjacent accommodating position 15, which is not limited here.

[0054] See also Figure 3 In some other embodiments, the heating element 10 includes a mounting seat 12 and a heating seat 14 disposed on the mounting seat 12, and the heating chamber 11 includes a third sub-chamber 116 and a fourth sub-chamber 118, wherein the third sub-chamber 116 is formed inside the mounting seat 12, and the fourth sub-chamber 118 is formed inside the heating seat 14 and communicates with the third sub-chamber 116; wherein the electrode assembly 30 extends into the third sub-chamber 116, and an accommodating position 15 surrounding the heating seat 14 is formed between the mutually facing outer surfaces of the mounting seat 12 and the heating seat 14. Optionally, the heating seat 14 is in the shape of an elongated strip, and the fourth sub-chamber 118 extends inside the heating seat 14 along the axial direction of the heating seat 14 and communicates with the third sub-chamber 116.

[0055] In other words, the heating seat 14 is configured as a heating needle, and a receiving position 15 for receiving the aerosol generating substrate is defined between the heating seat 14 and the mounting seat 12. When the atomizer 100 is used, the aerosol generating substrate is inserted on the heating seat 14, and the space between the outer surfaces of the heating seat 14 and the mounting seat 12 facing each other (i.e., the receiving position 15) receives and fixes the aerosol generating substrate. In addition, a third sub-cavity 116 is formed inside the mounting seat 12, and a fourth sub-cavity 118 connected to the third sub-cavity 116 is formed inside the heating seat 14. The electrode assembly 30 extends into the third sub-cavity 116. When the arc formed by the breakdown between the first electrode 32 and the second electrode 34 ionizes the gas in the third sub-cavity 116, plasma and heat are formed in the third sub-cavity 116, and the generated heat can also flow from the third sub-cavity 116 to the fourth sub-cavity 118, so that the heating seat 14 generates heat to heat the aerosol generating substrate.

[0056] See also Figure 4-Figure 5 In some other embodiments, the heating element 10 includes a mounting seat 12 and a heating seat 14 disposed on the mounting seat 12, a heating cavity 11 is formed inside the mounting seat 12, a second accommodating cavity with one end open is formed inside the heating seat 14, and the heating cavity 11 is located at the bottom of the second accommodating cavity which is opposite to the opening of the second accommodating cavity; wherein the second accommodating cavity is configured as an accommodating position 15. This is equivalent to forming a heating cavity 11 inside the mounting seat 12 of the heating element 10, generating heat in the heating cavity 11 through the action of the first electrode 32 and the second electrode 34, and the generated heat can be transferred to the second accommodating cavity of the top heating seat 14, that is, transferred to the accommodating position 15, so as to heat the aerosol generating substrate in the accommodating position 15.

[0057] See also Figure 4 Optionally, the heating seat 14 and the mounting seat 12 are integrally formed to simplify the device. Figure 5 Alternatively, the heating seat 14 and the mounting seat 12 are formed separately, and the heating seat 14 and the mounting seat 12 can be manufactured in a standardized manner, which makes it easy to manufacture the atomizer 100 as a standard part, thereby improving the versatility of the atomizer 100.

[0058] See also Figure 5 Furthermore, the heating seat 14 and the mounting seat 12 are formed separately, and after the heating seat 14 and the mounting seat 12 are fixedly connected, a heat conduction cavity 50 is defined between the two. The heat conduction cavity 50 is filled with a heat conduction medium, so that the heat generated inside the mounting seat 12 is efficiently transferred to the receiving position 15 of the heating seat 14 through the heat conduction medium, thereby ensuring the heat conduction performance. Among them, the heat conduction medium is a phase change interface heat transfer medium, such as toluene, water, naphthalene, thermal conductivity and aluminum bromide, which has good heat exchange efficiency.

[0059] See also Figure 6In one embodiment of the present application, an electronic atomization device 200 is also provided, including the above-mentioned atomizer 100, with a shorter preheating waiting time and a better atomization taste.

[0060] In some embodiments, the electronic atomization device 200 further includes a housing 210, and the atomizer 100 is disposed in the housing 210. An air inlet channel 211 is formed in the housing 210, which flows through the periphery of the heating element 10 and enters the receiving position 15. When the user inhales the electronic atomization device 200, after the outside air flows into the housing 210, it first flows through the periphery of the heating element 10, takes away the heat of the outer surface of the heating element 10, and at the same time, the temperature of the airflow itself is increased before entering the receiving position 15 to mix with the aerosol generated by atomization in the receiving position 15, and finally carries the aerosol into the user's mouth for the user to inhale. In this way, through the guidance of the air inlet channel 211, the airflow first passes through the periphery of the heating element 10 and then enters the receiving position 15. In this way, on the one hand, the periphery of the heating element 10 can be cooled down, and on the other hand, the airflow entering the receiving position 15 can be preheated to improve the atomization effect.

[0061] Specifically, the heating element 10 includes a mounting seat 12 and a heating seat 14 disposed on the mounting seat 12, and the heating chamber 11 includes a third sub-chamber 116 and a fourth sub-chamber 118, wherein the third sub-chamber 116 is formed inside the mounting seat 12, and the fourth sub-chamber 118 is formed inside the heating seat 14 and is connected to the third sub-chamber 116; wherein the electrode assembly 30 extends into the third sub-chamber 116, and the outer surfaces of the mounting seat 12 and the heating seat 14 facing each other are constructed to form a receiving position 15 surrounding the heating seat 14. In other words, the mounting seat 12 of the heating element 10 forms the third sub-chamber 116, and heat is generated in the third sub-chamber 116 through the action of the first electrode 32 and the second electrode 34, and the generated heat can be transferred to the fourth sub-chamber 118 of the heating seat 14 to heat the aerosol generating substrate inserted on the heating seat 15.

[0062] Furthermore, the air inlet channel 211 is constructed to flow through the periphery of the mounting seat 12 toward the accommodating position 15 , so that the air inlet channel 211 first flows through the periphery of the third sub-cavity 116 so that the airflow exchanges heat with the outer surface of the mounting seat 12 before entering the accommodating position 15 of the heating seat 14 .

[0063] It is understandable that in some other embodiments, the air intake channel 211 may not flow through the mounting seat 12 but directly enter the accommodating position 15 from the outside to simplify the airway structure. The setting of the air intake channel 211 is not limited herein.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
