[0038] The present invention provides an electronic atomization device comprising a device for heating an aerosol-generating substrate for atomization. In this embodiment, the aerosol-generating substrate can be a liquid aerosol-generating substrate, i.e., an aerosol liquid. In some embodiments, the electronic atomization device may include an atomizer 100 and a power supply assembly (not shown) detachably connected to the atomizer 100, the power supply assembly being electrically connected to the atomizer 100. The power supply assembly may include a battery for powering the atomizer 100. As shown in FIG1 , an atomizer 100 according to one embodiment of the present invention can be used to accommodate and heat an aerosol-generating substrate for atomization.

[0039] As shown in Figures 1 to 3, in some embodiments, an atomizer 100 includes an atomizer core 10 and a housing 20. The atomizer core 10 is accommodated in the housing 20. A liquid storage chamber 30 is formed in the housing 20. The liquid storage chamber 30 is used to store an aerosol-generating substrate such as an atomizing liquid. One side of the liquid storage chamber 30 is open and communicates with the heated atomizing assembly 2 to facilitate liquid supply to the heated atomizing assembly 2. A nozzle 5 is formed or mounted on the housing 20, and aerosol can be discharged through the nozzle 5.

[0040] As shown in Figure 3, the atomizer core 10 includes an upper cover 1, a heating atomizer assembly 2, a base 3 and an electrode 4. The upper cover 1 is arranged on the open side of the liquid storage chamber 30, and the heating atomizer assembly 2 is arranged in the upper cover 1; specifically, the upper cover 1 is provided with a accommodating chamber 11, and the heating atomizer assembly 2 is arranged in the accommodating chamber 11. The upper cover 1 is combined with the base 3, and the base 3 is against the heating atomizer assembly 2. The heating atomizer assembly 2 includes a heating element 21, and the heating element 21 includes a heating portion 211 and an electrode 4 lead portion that is conductively connected to the heating portion 211. The electrode 4 lead portion can extend outside the upper cover 1. The electrode 4 lead portion of the heating element 21 is conductively connected to the electrode 4. The electrode 4 leads the electrode 4 lead portion to the surface of the atomizer 100 to form an electrode 4 contact point, which is convenient for battery power supply. The electrode 4 is passed through the base 3 and is electrically connected to the electrode 4 lead portion on the heating element 21, thereby supplying power to the heating element 21.

[0041] 3 , 5 and 10 , a liquid guiding structure 12 is provided on the upper cover 1 , a liquid seepage surface 120 is formed on the liquid guiding structure 12 , an atomizing surface 210 is formed on the heating element 21 , and the atomizing surface 210 is arranged opposite to the liquid seepage surface 120 . Optionally, the atomizing surface 210 may be in contact with the liquid seepage surface 120 , so that the atomized liquid in the liquid guiding structure 12 can be conducted to the atomizing surface 210 of the heating element 21 through the liquid seepage surface 120 for heating.

[0042] 3 and 5 to 8 , the liquid-conducting structure 12 includes at least one longitudinal liquid-conducting groove 121 extending in the depth direction of the upper cover 1 , and at least one transverse liquid-conducting groove 122 extending in the length direction of the upper cover 1 . The longitudinal liquid-conducting groove 121 is connected to the transverse liquid-conducting groove 122 , so that liquid can flow in the longitudinal liquid-conducting groove 121 and the transverse liquid-conducting groove 122 to diffuse the liquid through the longitudinal liquid-conducting groove 121 into the transverse liquid-conducting groove 122 .

[0043] In combination with Figures 4, 5 and 7, in some embodiments, the upper cover 1 is provided with a liquid inlet hole 13 connecting the liquid storage chamber 30 and the heating element 21 of the heating atomization assembly 2. The liquid inlet hole 13 is located on the upper end surface of the upper cover 1. The liquid inlet hole 13 is connected to the longitudinal liquid guide groove 121. The liquid in the liquid storage chamber 30 enters the longitudinal liquid guide groove 121 of the upper cover 1 through the liquid inlet hole 13, and then diffuses to the transverse liquid guide groove 122, and then is conducted to the heating element 21 for heating and atomization to generate aerosol.

[0044] As shown in Figures 5 and 6, in some embodiments, the number of longitudinal liquid guiding grooves 121 is at least two, and at least two longitudinal liquid guiding grooves 121 are respectively arranged on both sides of the transverse liquid guiding groove 122. Correspondingly, two liquid inlet holes 13 are also arranged accordingly, so that liquid can be introduced from both sides and better diffused into the transverse liquid guiding groove 122.

[0045] In some embodiments, the number of the transverse liquid guiding grooves 122 is at least two, and the at least two transverse liquid guiding grooves 122 are arranged in parallel.

[0046] As shown in FIGS. 7 and 8, in some embodiments, at least two longitudinal liquid guiding grooves 121 and at least two transverse liquid guiding grooves 122 are arranged in a crisscross pattern. The longitudinal liquid guiding grooves 121 can be perpendicular to the transverse liquid guiding grooves 122. For example, as shown in FIG. 8, in this embodiment, the number of the longitudinal liquid guiding grooves 121 is three, and the number of the transverse liquid guiding grooves 122 is three. The longitudinal liquid guiding grooves 121 and the transverse liquid guiding grooves 122 are arranged in a crisscross pattern, for example, forming a "field" character structure as shown in the figure. Of course, the number of the longitudinal liquid guiding grooves 121 is not limited to three, and the number of the transverse liquid guiding grooves 122 is not limited to three, and their numbers and arrangement positions can be adjusted according to actual situations.

[0047] As shown in FIGS. 2 and 6, in some embodiments, the atomizer 100 further includes a seal 6, and the seal 6 is arranged at one end of the upper cover 1 close to the liquid storage cavity 30. The seal 6 can form a seal between the upper cover 1 and the housing 20 to prevent the liquid in the liquid storage cavity 30 from leaking out.

[0048] Combined with FIGS. 2 and 3, it can be understood that the atomized liquid is stored in the liquid storage cavity 30. The atomized liquid can enter the longitudinal liquid guiding grooves 121 through the liquid inlet holes 13, and then the liquid is diffused to各处 of the liquid guiding structure 12 through the respective transverse liquid guiding grooves 122, so that the liquid can be better conducted to the heating element 21 and the liquid conduction is more uniform. The electrode 4 lead wires of the heating element 21 are in contact with the electrode 4 of the atomizing core 10, and the electrode 4 of the atomizing core 10 forms an electrode 4 contact point on its surface. When the power supply component supplies power to the heating element 21 through the electrode 4 contact point, the heating element 21 conducts electricity to generate heat, and then heats the atomized liquid to generate aerosol.

[0049] As shown in FIGS. 3, 9 to 12, the heating and atomizing assembly 2 further includes a support bracket 22, and at least a part of the heating element 21 is embedded in the support bracket 22. This can improve the strength of the heating element 21 and make the heating and atomizing assembly 2 more convenient to assemble. The electrode 4 lead wire part can be arranged on the surface of the support bracket 22. A groove 221 is arranged on the support bracket 22, and the groove 221 can extend along both ends of the axis of the support bracket 22. The core heating area of the heating element 21 is arranged at the groove 221, and an atomizing channel 23 for gas to pass through is formed between the heating element 21 and the groove 221.

[0050] 2 to 5 , the upper cover 1 is provided with an airflow hole 14, and the heating atomizer assembly 2 is formed with an atomization channel 23. The atomization channel 23 is formed by the support bracket 22 and the heating element 21, and the atomization channel 23 is connected to the airflow hole 14. The atomizer core 10 of this embodiment has a straight atomization channel 23. This straight atomization channel 23 allows the aerosol to be discharged to the mouthpiece 5 more quickly, avoiding excessive condensation loss and providing a better user experience.

[0051] One side of the heating element 21 is attached to or embedded in the support bracket 22, and the other side of the heating element 21 is attached to the liquid guide 24. The atomization channel 23 is connected to the external air. The aerosol generated by the atomization of the heating element 21 is mixed with the external air and can be discharged through the atomization channel 23 and the air flow hole 14, and then enter the mouthpiece 5 for the user to inhale.

[0052] 3 and 11 to 12 , in some embodiments, the heating atomization assembly 2 further includes a liquid guide 24, which can be disposed in the accommodating cavity 11. In this case, the atomization channel 23 can be defined by the inner wall of the liquid guide 24 and the groove 221 on the support bracket 22. One end of the liquid guide 24 is in contact with the liquid permeability surface 120 of the liquid guide structure 12, and the other end of the liquid guide 24 is in contact with the atomization surface 210 of the heating element 21.

[0053] As shown in Figure 5, the liquid seepage surface 120 of the liquid-conducting structure 12 can be a planar structure, and the liquid-conducting liquid 24 can be spread flat on the plane. When the heating atomizing assembly 2 is assembled, the liquid-conducting liquid 24 is pressed tightly and fastened to the upper cover 1. In this way, the assembly is convenient and reliable, the liquid-conducting liquid 24 is pressed tightly by the upper cover 1, and the thickness of the liquid-conducting part is stable. The liquid in the liquid-conducting structure 12 can be replenished to the heating element 21 more quickly, and the longitudinal liquid-conducting groove 121 and the transverse liquid-conducting groove 122 can divide the atomized liquid. Optionally, the groove width of the longitudinal liquid-conducting groove 121 is greater than the groove width of the transverse liquid-conducting groove 122. The longitudinal liquid-conducting groove 121 is connected to the liquid storage chamber 30 above. The main function of the longitudinal liquid-conducting groove 121 is to guide the liquid in the liquid storage chamber 30. Therefore, the longitudinal liquid-conducting groove 121 needs to be set to a larger groove width so that it has a more sufficient liquid supply. The primary function of the transverse liquid-conducting grooves 122 is to evenly conduct liquid to all portions of the liquid-conducting body 24. Therefore, the transverse liquid-conducting grooves 122 are configured to have a relatively small width to form capillary grooves. These capillary grooves utilize the capillary tension of the liquid to prevent excessive liquid from penetrating the liquid-conducting body 24, thereby providing a superior leak-proofing effect. Due to the relatively small width of the transverse liquid-conducting grooves 122, the fine capillary grooves impart a greater capillary tension to the atomized liquid within the transverse liquid-conducting grooves 122. This capillary tension can offset some of the liquid's own gravity, preventing leakage due to its own weight.

[0054] Optionally, the width of the transverse liquid-conducting groove 122 is less than or equal to 2 mm. Preferably, the minimum width of the transverse liquid-conducting groove 122 is less than or equal to 1 mm, for example, the width of the transverse liquid-conducting groove 122 is preferably 0.4 mm to 0.8 mm. Preferably, the depth of the transverse liquid-conducting groove 122 is less than or equal to 1 mm, for example, the depth of the transverse liquid-conducting groove 122 is preferably 0.6 mm. This can provide the atomized liquid with better capillary tension and better leak-proofing.

[0055] The liquid guide structure 12 of the atomizer core 10 of the present invention is provided with a longitudinal liquid guide groove 121 and a transverse liquid guide groove 122. The liquid inlet hole 13 allows the atomized liquid to reach the guide body 24 through the longitudinal liquid guide groove 121 from the upper end surface of the upper cover 1. The atomized liquid is diffused to various parts of the guide body 24 through the transverse liquid guide groove 122. At the same time, the atomized liquid has a large capillary tension within the transverse liquid guide groove 122 of the liquid guide structure 12. The capillary tension can offset part of the gravity of the atomized liquid itself, so the atomized liquid is not easily leaked due to its own weight. At the same time, the atomized liquid stored in the liquid guide structure 12 has a shorter distance to reach the heating element 21, and can provide a relatively sufficient amount of atomized liquid to the guide body 24. At the same time, in conjunction with Figure 13, these longitudinal liquid guide grooves 121 and transverse liquid guide grooves 122 can prevent the entry of external gas. The capillary force of the atomized liquid itself can prevent the gas from entering the liquid storage chamber 30 from the liquid inlet channel 7 (the liquid inlet channel 7 refers to the portion connected to the liquid inlet hole 13 and the longitudinal liquid guide groove 121), so that the gas can only enter from the ventilation channel 8, so that the gas and liquid paths are separated. Here, the gas entering the liquid storage chamber 30 refers to the cavity left after the atomized liquid is consumed. The air pressure in the liquid storage chamber 30 is low, and the external air pressure is high. The external gas has a tendency to enter the liquid storage chamber 30. When the pressure difference exceeds the balance, the external gas will be squeezed into the liquid storage chamber 30 by the gas pressure, as shown in Figure 2. The gas flow direction is shown by the arrow in the figure. The ventilation channel 8 is mainly formed inside the upper cover 1 and in the gap between the upper cover 1 and the seal 6. The gas flows out from the gap between the upper cover 1 and the seal 6 through the internal gap of the upper cover 1.

[0056] It is understandable that the above embodiments only express the preferred implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
