[0039] An embodiment of this application provides an atomization core 100. The atomization core 100 is used to heat an atomizable liquid matrix to generate an aerosol, such as Figure 1 As shown, the atomization core 100 includes a porous body 10 and a heating element 20. At least a part of the heating element 20 is combined with the porous body 10. The porous body 10 is used to absorb the liquid matrix and conduct the liquid matrix to the heating element 20. The heating element 20 is used to heat and atomize the liquid matrix introduced by the porous body 10 to generate an aerosol.

[0040] The porous body 10 can be porous glass or porous ceramic, etc. Its inner wall contains a network structure with interconnected pores and has good liquid absorption and liquid conduction characteristics. The heating element 20 can be a heating film, a resistance wire, a heating sheet, or a heating mesh, etc. combined with the porous body 10, and is used to heat and atomize a part of the liquid matrix held inside the porous body 10 to generate an aerosol.

[0041] Such as Figure 2As shown, the heating element 20 includes a conductive electrode 21 and a heating portion 22 electrically connected to the conductive electrode 21. The heating portion 22 is configured into a special pattern or trace route so as to be able to provide an appropriate resistance value. The above-mentioned pattern or trace line can be combined on the surface of the porous body 10 by means such as printing, vapor deposition or sintering.

[0042] The porous body 10 includes a first surface 11 and a second surface 12 which are oppositely arranged. The first surface 11 is used to receive the liquid matrix and transfer the liquid matrix to the second surface 12. A first groove 121 recessed towards the first surface 11 is formed on the second surface 12. The heating portion 22 is embedded inside the porous body 10, and a part of the heating portion 22 is exposed to the first groove 121. After the first surface 11 receives the liquid matrix, the liquid matrix is then transferred to the heating portion 22 through the internal voids of the porous body 10. The heating portion 22 can heat and atomize the liquid matrix to generate an aerosol, and the aerosol can be released from the first groove 121.

[0043] In this embodiment, by providing the first groove 121, the distance for the liquid matrix to conduct to the heating portion 22 can be shortened, thereby improving the heating efficiency of the atomization core 100. Moreover, there are distances maintained between the four edges of the first groove 121 and the second surface 12, as Figure 1 shown by the distance d1 and the distance d2, so as to avoid excessive reduction in the structural strength of the porous body 10 due to the formation of the first groove 121 on the second surface 12. Thus, the porous body 10 does not need to be set with an overly thick thickness to improve the structural strength, which is beneficial for shortening the distance for the liquid matrix to conduct to the heating portion 22. In some embodiments, as Figure 1 shown, a second groove 122 recessed towards the first surface 11 is further formed on the second surface 12. The second groove 122 is arranged at intervals with the first groove 121. The conductive electrode 21 is exposed to the second groove 122, so as to facilitate the electrical connection between the electrode post or the wire lead and the conductive electrode 21.

[0044] Furthermore, in some embodiments, as Figure 1 shown, one side of the second groove 122 communicates with the edge of the second surface 12, so that the second groove 122 forms a notch 1221. When the atomization core 100 has its own electrode lead, the electrode lead can be conveniently welded to the conductive electrode 21 through the notch 1221.

[0045] And, in some embodiments, as Figure 1 shown, the area of the bottom surface 1211 of the first groove 121 is larger than the area of the bottom surface 1222 of the second groove 122. Thus, the area of the heating portion 22 combined on the bottom surface 1211 of the first groove 121 can be larger, thereby improving the heating efficiency of the atomization core 100.

[0046] Also, in some embodiments, the heating part 22 is bent and extended along the length direction of the first groove 121, so as to increase the heating area of the heating part 22, and further improve the heating efficiency of the atomization core 100. Specifically, the heating part 22 can be, for example, Figure 1 the square wave shape shown. Or, in some other embodiments, the heating part 22 can also be any one of a spiral shape, a sawtooth shape, or a serpentine shape, etc. The present application does not limit this, as long as the heating area of the heating part 22 can be increased.

[0047] Furthermore, in some embodiments, as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the heating part 22 / 22a includes a heating track 221 / 221a and a plurality of bonding parts 222 / 222a connecting two adjacent heating tracks. The bonding parts 222 / 222a extend along the width direction of the first groove 121, and at least a part of the bonding parts 222 / 222a is embedded in the porous body 10 to prevent the local warping of the heating track 221 / 221a, so that the heating track 221 / 221a remains in a planar state and fits on the bottom surface of the first groove 121.

[0048] It should be noted that the width of the bonding part 222 / 222a is greater than the width of the heating track 221 / 221a, so that the resistance of the bonding part 222 / 222a is less than the resistance of the heating track 221 / 221a, to reduce the energy consumed on the bonding part 222 / 222a, and further improve the heating efficiency of the atomization core 100.

[0049] Also, in some embodiments, as Figure 2 shown, the bonding part 222 or the conductive electrode 21 has a plurality of anchoring parts 2221. The anchoring parts 2221 are perpendicular to the plane where the heating part 22 is located, that is, perpendicular to the bottom surface of the first groove 121, so that the anchoring parts 2221 are vertically inserted into the porous body 10 to prevent the heating body 20 from delaminating the porous body 10 during the sintering process, so as to improve the bonding force of the porous body 10.

[0050] In some embodiments, as Figure 2 shown, the conductive electrode 21 and the heating part 22 are kept on the same plane, and further, on the premise of ensuring the heating efficiency, the extension length of the heating body 20 is minimized as much as possible, so as to reduce the manufacturing cost of the heating body 20.

[0051] Furthermore, in some embodiments, as Figure 1As shown, when the heating element 20 is combined with the porous body 10, the conductive electrode 21 and the heating part 22 are maintained on the same plane. The heating part 22 is combined on the bottom surface 1211 of the first groove 121, while the conductive electrode 21 is combined on the bottom surface 1222 of the second groove 122, and the bottom surface 1211 of the first groove 121 and the bottom surface 1222 of the second groove 122 are on the same plane, or rather, the first groove 121 and the second groove 122 have the same depth, so that when the heating element 20 is combined with the porous body 10, the conductive electrode 21 and the heating part 22 are maintained on the same plane.

[0052] And, in some embodiments, as Figure 1 shown, the second groove 122 includes two, and the two second grooves 122 are arranged on both sides of the first groove 121. The positive electrode of the conductive electrode 21 is exposed in one of the second grooves 122, while the negative electrode of the conductive electrode 21 is exposed in the other second groove 122 to facilitate the electrical connection between the atomization core 100 and an external electrical connection device. In some embodiments, the first groove 121 has a depth of 0.2 mm to 0.8 mm. If the depth of the first groove 121 is too small, it is not sufficient to shorten the distance for the liquid matrix to transfer to the heating part 22, thus the heating efficiency of the atomization core 100 cannot be effectively improved; while if the depth of the first groove 121 is too large, the aerosol released from the bottom surface 2411 of the first groove 121 is likely to accumulate in the first groove 121.

[0053] In some embodiments, as Figure 3 shown, the porous body 10 does not need to be provided with the second groove 122, and only the first groove 121 needs to be provided. The conductive electrode 21 and the heating part 22 are maintained on the same plane, and the conductive electrode 21 extends out of the side of the porous body 10 so that the conductive electrode 21 is exposed, in order to facilitate the electrical connection between the atomization core 100 and an external electrical connection device.

[0054] As Figure 5 shown, for the heating element provided by another embodiment of the present application, the conductive electrode 21a and the heating part 22a of the heating element are not on the same plane, and the conductive electrode 21a and the heating part 22a are connected through a bent connecting part 23a, and thus the conductive electrode 21a can be exposed on the second surface 12, as Figure 4 shown, and are located on both sides of the first groove 121, that is, the positive electrode of the conductive electrode 21a is located on one side of the first groove 121, while the negative electrode is located on the other side of the first groove 121. Since the conductive electrode 21a is directly exposed on the second surface 12, it can facilitate the electrical connection between the atomization core 100 and an external electrical connection device.

[0055] And, it should be noted that, as Figure 2As shown, the width of the conductive electrode 21 is greater than the width of the heating part 22. The heating track 221 of the heating part 22 is in an elongated shape, so that the resistance of the conductive electrode 21 is less than the resistance value of the heating part 22. As a result, less heat is generated by the conductive electrode 21, and the heat of the atomization core 100 is mainly generated by the heating part 22 to improve the heating efficiency of the atomization core 100.

[0056] An embodiment of the present application further provides an atomizer 200. The atomizer 200 includes the atomization core 100 described in the above embodiment. As Figure 6 shown, the atomizer 200 includes a mouthpiece part 210, a liquid storage part 220 and a base 230. The liquid storage part 220 has opposite proximal and distal ends. The mouthpiece part 110 is installed at the proximal end, and an air outlet 211 for aerosol to escape from the atomizer 100 is provided on the mouthpiece part 210. When a user sucks at the air outlet 211, the aerosol formed after atomization can be inhaled. The distal end is provided with an open end, and the base 230 extends at least partially into the liquid storage part 220 through the open end at the distal end, so as to provide support for the components in the liquid storage part 220.

[0057] A hollow cylindrical structure 240 extending axially is provided inside the liquid storage part 220. The hollow area 241 of the hollow cylindrical structure 240 serves as a liquid storage cavity of the atomizer 200 for storing liquid matrices such as atomizable liquid medicine or e-cigarette liquid. When the liquid stored in the liquid storage cavity 241 is liquid medicine, the atomizer 200 can be used as a medical atomizer for treating respiratory diseases; when the liquid stored in the liquid storage cavity 241 is e-cigarette liquid, the atomizer 200 can be used as an e-cigarette. The liquid storage cavity 241 is provided with a liquid outlet 2411 for the liquid matrix to flow out of the liquid storage cavity 241.

[0058] Please continue to refer to Figure 6 , a first air flow channel 242 and a second air flow channel 243 are defined between the hollow cylindrical structure 240 and the inner wall of the liquid storage part 220. The aerosol generated by the atomization core 100 atomizing the liquid matrix can flow into the mouthpiece 210 through the first air flow channel 242 and the second air flow channel 243, and then flow to the air outlet 211 for the user to inhale.

[0059] Please continue to refer to Figure 6, the atomizer 200 further includes a first seal 250. The first seal 250 is fixed on the liquid storage part 220 and adjacent to the liquid storage port 2411. The first seal 250 is formed with a holding chamber (not shown in the figure), and the atomization core 10 is fixed in this holding chamber. The first seal 250 is made of a flexible material such as silica gel, rubber or latex. Since the flexible material has elasticity, the first seal 250 can elastically abut between the liquid storage part 220 and the atomization core 100, thereby sealing the assembly gap between the liquid storage part 220 and the atomization core 100, and preventing the liquid matrix from leaking through the assembly gap between the liquid storage part 220 and the atomization core 100 after flowing out of the liquid outlet 2411, so that the liquid matrix only flows to the atomization core 100. It is easy to understand that the first seal 250 is formed with a through hole 251 for the liquid matrix to flow through, and the through hole 251 is communicated with the liquid outlet 2411. The liquid matrix can flow to the atomization core 100 through the liquid outlet 2411 and the through hole 251.

[0060] An air inlet 231 and an electrode hole are provided on the base 230. An electrode post 232 is inserted into the electrode hole. One end of the electrode post 232 is exposed outside the housing of the atomizer 200 for electrical connection with a power supply mechanism used in conjunction with the atomizer 200, and the other end extends to the atomization core 100 for electrical connection with the conductive electrode of the atomization core 100, and can also provide support for the atomization core 100. Thus, the power supply mechanism can supply the electrical energy required for heating to the atomization core 100 through the electrode post 232.

[0061] Please continue to refer to Figure 6 , a second seal 260 is supported on the base 230. The second seal 260 can be a flexible soft rubber part such as silica gel, rubber or latex. The second seal 260 is in interference fit with the inner wall of the liquid storage part 220 to seal the distal end 222 of the liquid storage part 220. The second seal 260 is disposed opposite to the atomization core 100 and defines an atomization chamber 261, and the aerosol generated by heating and atomizing the liquid matrix by the atomization core 100 is released therein.

[0062] When the user uses the atomizer 200 for suction, external cold air enters the atomization chamber 261 and mixes with the high-temperature aerosol in the atomization chamber 261. Part of the high-temperature aerosol will condense to form condensate and drip down when it encounters the external cold air. The seal formed by the second seal 260 can prevent the dripping condensate from leaking out from the distal end of the liquid storage part 220.

[0063] The air inlet 231 provides an air flow inlet for external air to enter the atomizer 200. A ventilation hole 261 is formed in the second seal 260, and the ventilation hole 261 communicates the air inlet 231 and the atomization chamber 261. Thus, when the user sucks, a negative pressure is generated inside the atomization chamber 261, prompting the external air to flow through the air inlet 231 and the ventilation hole 261 into the atomization chamber 261, and then carrying the aerosol in the atomization chamber 261 into the first air flow channel 242 and the second air flow channel 243, and then flowing into the mouthpiece 210 through the first air flow channel 242 and the second air flow channel 243, and finally escaping from the atomizer 200 through the air outlet 211 of the mouthpiece 210 for the user to inhale, thereby forming the air flow path of the atomizer 200, as Figure 6 shown by the arrow route R in

[0064] It should be noted that the present application does not limit the specific structure of the atomizer 200. Those skilled in the art can change the specific structure of the atomizer 20 according to specific application scenarios. The atomizer 200 only needs to include a liquid storage cavity for storing the liquid matrix, an air inlet for allowing external air to enter the atomizer 200, and an air outlet for allowing the aerosol formed after atomization by the atomization core 100 to escape from the atomizer 200.

[0065] An embodiment of the present application also provides an electronic atomization device 300, which can be seen in Figure 7 As shown, the electronic atomization device 300 includes an atomizer 200 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply component 400 that powers the atomizer 200.

[0066] In an alternative embodiment, for example Figure 7 As shown, the power supply component 400 includes a receiving cavity 410 provided at one end along the length direction for receiving and accommodating at least a part of the atomizer 200, and electrical contacts 420 at least partially exposed on the surface of the receiving cavity 410, for forming an electrical connection with the electrode 232 of the atomizer 200 to power the atomizer 200 when at least a part of the atomizer 200 is received and accommodated in the power supply component 400.

[0067] A seal 430 is provided in the power supply component 400, and at least a part of the internal space of the power supply component 400 is separated by the seal 430 to form the above-mentioned receiving cavity 410. In Figure 7 In the preferred embodiment shown, the seal 430 is configured to extend along the cross-sectional direction of the power supply component 400, and is preferably made of a flexible material such as silica gel, so as to prevent the liquid matrix seeping from the atomizer 200 to the receiving cavity 410 from flowing to components such as the controller 440 and the sensor 450 inside the power supply component 400.

[0068] In Figure 7In the preferred embodiment shown, the power supply assembly 400 also includes a battery cell 460 for powering the battery at the other end away from the receiving cavity 410 along the length direction; and a controller 440 disposed between the battery cell 460 and the receiving cavity 410, which is operable to guide current between the battery cell 460 and the electrical contact 420.

[0069] During use, the power supply assembly 400 includes a sensor 450 for sensing the suction airflow generated when the user inhales through the air outlet of the atomizer 200 , and then the controller 440 controls the battery cell 460 to output current to the atomizer 200 according to the detection signal of the sensor 450 .

[0070] Further in Figure 7 In the preferred embodiment shown, the power supply assembly 400 is provided with a charging interface 470 at the other end away from the receiving cavity 410 for charging the battery cell 460 .

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Under the concept of the present application, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes in different aspects of the present application as described above, which are not provided in detail for the sake of simplicity. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
