[0038] The utility model constructs an electronic atomization device, which includes a substrate for heating and atomizing an aerosol. In this embodiment, the aerosol-generating substrate can be a liquid aerosol-generating substrate, that is, an atomizing 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, and the power supply assembly is electrically connected to the atomizer 100. The power supply assembly may include a battery for powering the atomizer 100. Figure 1 As shown, an atomizer 100 according to an embodiment of the present invention can be used to contain and heat an atomized aerosol-generating substrate.

[0039] like Figures 1 to 3 As shown, in some embodiments, the 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 aerosol generating substrates such as atomizing liquid, one side of the liquid storage chamber 30 is open, and the liquid storage chamber 30 is connected to the heating atomizing assembly 2 to facilitate the supply of liquid to the heating atomizing assembly 2. A nozzle 5 is formed or installed on the housing 20, and the aerosol can be discharged through the nozzle 5.

[0040] like Figure 3 As shown, 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 body 21, and the heating body 21 includes a heating part 211 and an electrode 4 lead part conductively connected to the heating part 211, and the electrode 4 lead part can extend outside the upper cover 1. The electrode 4 lead part of the heating body 21 is conductively connected to the electrode 4. The electrode 4 leads the electrode 4 lead part out on the surface of the atomizer 100 to form an electrode 4 contact, which is convenient for battery power supply. The electrode 4 is arranged on the base 3 and is electrically connected to the electrode 4 lead part on the heating body 21, so as to supply power to the heating body 21.

[0041] Combination Figure 3 , Figure 5 and Fig.10 A liquid guiding structure 12 is provided on the upper cover 1, a liquid permeation surface 120 is formed on the liquid guiding structure 12, an atomizing surface 210 is formed on the heating element 21, the atomizing surface 210 is arranged opposite to the liquid permeation surface 120, optionally, the atomizing surface 210 can contact the liquid permeation 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 permeation surface 120 for heating.

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

[0043] Combination Figure 4 , Figure 5 and Figure 7 In some embodiments, a liquid inlet hole 13 is provided on the upper cover 1 to connect 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] like Figure 5 and Figure 6As shown, 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 correspondingly arranged, 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 transverse liquid guiding grooves 122 is at least two, and at least two transverse liquid guiding grooves 122 are arranged in parallel.

[0046] As Figure 7 and Figure 8 shown, 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 Figure 8 shown, in this embodiment, the number of longitudinal liquid guiding grooves 121 is three, and the number of 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 longitudinal liquid guiding grooves 121 is not limited to three, and the number of transverse liquid guiding grooves 122 is not limited to three. Their numbers and arrangement positions can be adjusted according to actual situations.

[0047] As Figure 2 and Figure 6 shown, in some embodiments, the atomizer 100 further includes a seal 6. 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 Figure 2 and Figure 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 each transverse liquid guiding groove 122, so that the liquid can be better conducted to the heating element 21 and the liquid conduction is more uniform. The electrode 4 leads of the heating element 21 are in contact with the electrode 4 of the atomization core 10. The electrode 4 of the atomization core 10 forms an electrode 4 contact point on its surface. When the power supply assembly supplies power to the heating element 21 through this electrode 4 contact point, the heating element 21 conducts electricity to generate heat, thereby heating the atomized liquid to generate aerosol.

[0049] As Figure 3 , Figures 9 to 12As shown, the heating atomization assembly 2 also includes a support bracket 22, and the heating element 21 is at least partially embedded in the support bracket 22. In this way, the strength of the heating element 21 can be improved, so that the heating atomization assembly 2 can be assembled more conveniently. The lead portion of the electrode 4 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 be extended 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 atomization channel 23 for gas to pass through is formed between the heating element 21 and the groove 221.

[0050] Combination Figures 2 to 5 The upper cover 1 is provided with an air flow hole 14, and the heating atomization assembly 2 is provided with an atomization channel 23, which is formed by the support bracket 22 and the heating element 21, and the atomization channel 23 is connected with the air flow hole 14. A straight atomization channel 23 is formed in the atomization core 10 of this embodiment, and the straight atomization channel 23 can make the aerosol be discharged to the suction nozzle 5 faster, which can avoid excessive condensation loss and provide a better 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-conducting liquid 24. The atomization channel 23 is connected to the external gas. The aerosol generated by the atomization of the heating element 21 is mixed with the external gas and can be discharged through the atomization channel 23 and the air flow hole 14, and then enter the suction nozzle 5 for the user to inhale.

[0052] Combination Figure 3 and Figure 11 to Figure 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 permeation 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] like Figure 5As shown, the liquid permeation surface 120 of the liquid-conducting structure 12 can be a planar structure, and the liquid-conducting liquid 24 can be laid flat on the plane. When the heating atomizing assembly 2 is assembled, the liquid-conducting liquid 24 is pressed and snapped onto the upper cover 1. In this way, the assembly is convenient and reliable, the liquid-conducting liquid 24 is pressed 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 upper liquid storage chamber 30. 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 main function of the transverse liquid guiding groove 122 is to evenly conduct the liquid to all parts of the liquid guiding liquid 24, so the transverse liquid guiding groove 122 needs to be set to a smaller groove width to form a capillary groove, which can use the capillary tension of the liquid to prevent excessive liquid from penetrating into the liquid guiding liquid 24, and can achieve a better leak-proof effect. Since the groove width of the transverse liquid guiding groove 122 is small, the formation of a small capillary groove can make the atomized liquid have a larger capillary tension in the transverse liquid guiding groove 122, and the capillary tension can offset part of the gravity of the liquid itself, avoiding the problem of liquid 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 make the atomized liquid have better capillary tension and better leakage prevention effect.

[0055] The liquid-conducting structure 12 of the atomizing core 10 of the utility model is provided with a longitudinal liquid-conducting groove 121 and a transverse liquid-conducting groove 122. The liquid inlet hole 13 allows the atomized liquid to reach the liquid-conducting body 24 through the longitudinal liquid-conducting groove 121 from the upper end surface of the upper cover 1, and the atomized liquid is diffused to all parts of the liquid-conducting body 24 through the transverse liquid-conducting groove 122. At the same time, the atomized liquid has a large capillary tension in the transverse liquid-conducting groove 122 of the liquid-conducting structure 12. The capillary tension can offset part of the gravity of the atomized liquid itself, so the atomized liquid is not easy to leak due to its own weight. At the same time, the atomized liquid stored in the liquid-conducting structure 12 has a shorter distance to reach the heating element 21, and can be supplied with a relatively sufficient amount of atomized liquid to the liquid-conducting body 24. At the same time, combined with Fig.13These longitudinal liquid guiding grooves 121 and transverse liquid guiding 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 part including the liquid inlet hole 13 and the longitudinal liquid guiding groove 121 connected), 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 relatively 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. Figure 2 As shown, 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 the gap between the upper cover 1 and the seal 6, and 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 can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
