In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] See also Figure 1-3The embodiment of the utility model provides an electronic atomization device, in which an atomization channel 10 and an air inlet channel 20 and an air outlet channel 30 respectively connected to the atomization channel 10 are provided. The electronic atomization device also includes a guide portion 1 and an atomization core 2 at least partially arranged in the atomization channel 10, wherein one end of the air inlet channel 20 is connected to the outside, and the other end forms an air inlet 201 connected to the atomization channel 10; the atomization core 2 has a heating surface 21, on which a heating body 3 is provided, and the heating surface 21 has a heating element 3 parallel to the inside of the atomization channel 10. A first direction of the air flow path and a second direction intersecting with the first direction; the guide portion 1 has a guide groove 11 inclined from the air inlet 201 to the heating surface 21, the guide groove 11 corresponds to the heating element 3, and the first dimension W1 of the guide groove 11 along the second direction is at least 0.5 times the second dimension W2 of the heating area of ​​the heating element 3 along the second direction; the air inlet 201 extends along the second direction, and the air inlet 201 has a third dimension W3 along the second direction and a fourth dimension W4 along the first direction, and the third dimension W3 is larger than the fourth dimension W4.

[0032] In the embodiment of the utility model, the atomized liquid infiltrates into the atomizing core 2, and is heated by the heating element 3 on the heating surface 21 to generate a high-temperature aerosol. The external airflow can flow to the guide groove 11 through the air inlet 201 of the air inlet channel 20. After being guided by the guide groove 11, the airflow flows to the atomizing channel 10 and takes the aerosol away from the atomizing channel 10. The airflow and the aerosol then flow together to the air outlet channel 30, and finally flow together from the air outlet channel 30 to the outside. By setting the air inlet 201 to extend along the second direction, and the third dimension W3 of the air inlet 201 extending along the second direction is greater than the second dimension W4 extending along the first direction, the air inlet 201 has a larger airflow coverage area along the second direction of the heating surface 21. The airflow is guided by the inclined surface of the guide groove 11, so that the airflow flows to the heating surface 21 relatively smoothly, thereby reducing the turbulence formed by the airflow vertically impacting the heating surface 21. In addition, since the guide groove 11 has two side walls relative to each other along the second direction, the airflow can cover most of the heating area of ​​the heating element 3 through the limiting effect of the two side walls, avoiding excessive dispersion, so that the airflow can better bring the aerosol out from the heating surface 21, and finally the airflow can bring a large amount of aerosol from the atomization channel to the air outlet channel 30, so that a large amount of aerosol in the air outlet channel 30 can flow to the outside, thereby improving the atomization amount and atomization effect.

[0033] It can be understood that the first direction is the length direction of the heating surface 21, and the second direction is the width direction of the heating surface 21. In addition, the heating surface 21 extends in the transverse direction, so the length direction of the heating surface 21 is parallel to the transverse direction, that is, the first direction is parallel to the transverse direction. Figure 2The direction parallel to the X direction of the coordinate system in the figure is the width direction of the heating surface 21, which is the second direction; the direction parallel to the Y direction of the coordinate system in the figure is the horizontal direction, which is also the length direction of the heating surface 21, which is the first direction; the direction parallel to the Z direction of the coordinate system in the figure is the longitudinal direction.

[0034] Furthermore, the projection of the central axis of the air inlet 201 onto the plane where the heating surface 21 is located is located on the same central axis as the center of the heating area, and the central axis is parallel to the first direction.

[0035] Specifically, taking the direction from the air inlet 201 to the atomization channel 10 as the positive direction, the air inlet 201 is located at a position obliquely below the heating surface 21. The heating element 3 is arranged on the heating surface 21, and the center of the heating area of ​​the heating element 3 is located on the heating surface 21. The airflow flowing out of the air inlet 201 will flow to the atomization channel 10 after being guided by the guide groove 11. The projection position of the central axis of the air inlet 201 on the plane where the heating surface 21 is located and the position of the center of the heating area on the heating surface 21 are on the same central axis. Therefore, when the airflow flows to the atomization channel 10, the airflow can flow directly to the heating area of ​​the heating element 3, so that most of the airflow is concentrated in the atomization area, that is, the airflow is concentrated in the aerosol generation area, and then the aerosol can be better brought out from the heating area of ​​the heating element 3, thereby improving the atomization amount and the atomization effect.

[0036] Furthermore, the ratio of the first size W1 to the second size W2 is 0.7-1.4.

[0037] Specifically, the ratio of the first size W1 to the second size W2 can be 0.7, 0.8, 0.9, 0.95, 1.0, 1.05, 1.1, 1.2, 1.3, 1.4, etc. After the external airflow flows out from the air inlet 201, it will pass through the guide groove 11 and then flow to the heating element 3 of the heating surface 21. By setting the ratio of the first size of the guide groove 11 and the second size of the heating area of ​​the heating element 3 to 0.7-1.4, the airflow flowing to the heating element 3 through the guide groove 11 can cover the main heating area of ​​the heating element 3, that is, the airflow can cover the main atomization area, and can avoid the first size W1 of the guide groove 11 being too large to cause the airflow to be dispersed in the guide groove 11, so that the airflow can be better concentrated in the aerosol generation area, and the airflow can bring out most of the aerosol, thereby improving the atomization amount and atomization effect.

[0038] Furthermore, the first dimension W1 is equal to the second dimension W2. By setting the dimensions of the heating element 3 and the guide groove 11 along the second direction to be the same, the main heating area of ​​the heating element 3 can be covered to the greatest extent, and the air flow dispersion and the like can be well avoided, thereby maximizing the atomization amount and atomization effect.

[0039] Specifically, the atomizer core 2 may be ceramic. The size of the heating element 3 in the heating area of ​​the heating surface 21 along the second direction may be 2-10 mm, that is, the second size of the heating element 3 may be 2-10 mm. The size of the guide groove 11 along the second direction may be 2-10 mm, that is, the first size of the guide groove 11 may be 2-10 mm. The first size is equal to the second size. For example, if the second size of the heating element 3 is 5 mm, the first size of the guide groove 11 is also 5 mm.

[0040] Furthermore, a ratio of the third size W3 to the second size W2 is 0.5-1.5.

[0041] Specifically, the ratio of the third dimension W3 to the second dimension W2 can be 0.5, 0.6, 0.7, 0.8, 0.9, 0.95, 1.0, 1.05, 1.1, 1.2, 1.3, 1.4, 1.5, etc. By setting the ratio of the third dimension of the air inlet 201 to the second dimension of the heating area of ​​the heating element 3 to 0.5-1.5, the airflow volume can be controlled to ensure that the airflow covers the heating area of ​​the heating element 3, that is, the airflow can contact most of the aerosol; in addition, the airflow velocity can be increased, so that the airflow coming out of the air inlet 201 has a higher overall velocity when passing through the heating area of ​​the heating element 3, and the high-speed airflow can bring out more aerosol and increase the amount of smoke.

[0042] Further, the third size W3 is equal to the first size W1, and the second size W3 is equal to the second size W2.

[0043] In some specific embodiments, along the second direction, the size of the air inlet 201 is equal to the size of the guide groove 11 and equal to the size of the heating element 3, thereby ensuring the flow rate of the airflow when flowing out from the air inlet 201; at the same time, the airflow flowing out from the air inlet 201 can just cover the area of ​​the guide groove 11 in the second direction, and the airflow will not disperse in the guide groove 11 when flowing in the guide groove 11; and the airflow after passing through the guide groove 11 can completely cover the heating area of ​​the heating element 3, and can bring out most of the aerosol, thereby increasing the atomization amount and atomization effect.

[0044] Furthermore, a ratio of the third dimension W3 to the fourth dimension W4 is 1.2-4.

[0045] Specifically, the ratio of the third dimension W3 to the fourth dimension W4 may be 1.2, 1.5, 1.8, 2.0, 2.5, 2.8, 3.0, 3.2, 3.5, 3.8, 4.0, etc. The air inlet 201 may be in a runway shape, an ellipse shape, a rectangle shape, or other long strip shapes. The size of the air inlet 201 in the second direction is larger than the size in the first direction, so that the air inlet 201 extends in the second direction, so that the air inlet 201 has a larger airflow coverage area in the second direction along the heating surface 21, and most of the aerosol can be brought out.

[0046] Further, in some embodiments, the third size W3 is smaller than or equal to the first size W1, and the first size W1 is smaller than or equal to the second size W2.

[0047] Specifically, the dimension of the air inlet 201 extending along the second direction is less than or equal to the dimension of the guide groove 11 extending along the second direction, and the dimension of the guide groove 11 extending along the second direction is less than or equal to the dimension of the heating element 3 extending along the second direction, so that the airflow flowing out of the air inlet 201 can have a larger flow rate, and at the same time, it can still maintain a certain flow rate after passing through the guide groove 11 and can cover the main heating area of ​​the heating element 3, so that after the airflow flows out from the air inlet 201 at a high speed, it can flow more concentratedly to the heating surface 21, and the high-speed airflow can bring out more aerosol, thereby improving the atomization amount and atomization effect.

[0048] Furthermore, the inclination angle θ of the guide groove 11 is 10°-80°.

[0049] Specifically, the inclination angle θ of the guide groove 11 is the angle between the inclined surface of the guide groove 11 and the plane where the air inlet 201 is located. The inclination angle θ of the guide groove 11 can be 10°, 15°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, etc. After the airflow flows out from the air inlet 201 at a high speed, it flows into the guide groove 11, and the airflow is guided by the inclined surface of the guide groove 11, so that the airflow flows relatively smoothly to the heating surface 21, effectively reducing the flow velocity loss, and facilitating the full guidance of the airflow to the heating surface 21. The high-speed airflow can bring out more atomized gas from the atomization chamber and increase the amount of smoke.

[0050] Furthermore, the air flow area of ​​the air inlet passage 20 gradually decreases along the direction of the air inlet 201 .

[0051] Specifically, along the longitudinal direction of the oil cup 4, the air flow area of ​​the air inlet channel 20 gradually decreases from the end away from the air inlet 201 to the direction of the air inlet 201. When the amount of gas inlet is the same, the smaller the air flow area of ​​the air inlet channel 20, the greater the air flow rate. Therefore, during the process of the air flow flowing in the air inlet channel 20, the air flow rate gradually increases until the air flow reaches the air inlet 201, the air flow can flow out at a higher flow rate, so that it can eventually pass through the heating surface 21 more quickly and take away more aerosol.

[0052] Further, the air inlet channel 20, the atomization channel 10 and the air outlet channel 30 are sequentially connected along the first direction, and the air inlet channel 20 and the air outlet channel 30 extend in a longitudinal direction perpendicular to the first direction and the second direction.

[0053] Specifically, the heating surface 21 extends in the transverse direction, and the first direction is parallel to the transverse direction. Along the transverse direction, the electronic atomization device is sequentially arranged with an air inlet channel 20, an atomization channel 10, and an air outlet channel 30. The longitudinal direction is perpendicular to the first direction and to the second direction. The air inlet channel 20 extends in the longitudinal direction, and the air outlet channel 30 extends in the longitudinal direction. The external airflow first flows in the air inlet channel 20 in the longitudinal direction, flows to the air inlet 201, flows to the atomization channel 10 along the first direction through the guide portion 1, flows in the atomization channel 10 along the first direction, and takes the aerosol from the atomization channel 10 to the air outlet channel 30 and the port connected to the atomization channel 10, and finally flows in the air outlet channel 30 in the longitudinal direction.

[0054] Furthermore, in some specific embodiments, the electronic atomization device also includes an oil cup 4, a suction nozzle 6 connected to one end of the oil cup 4 along the longitudinal direction, and a base 5 connected to the other end of the oil cup 4, wherein the oil cup 4 has a liquid storage chamber 40 and an air outlet channel 30 arranged along a first direction; an atomization channel 10 is defined between the base 5 and the end of the oil cup 4 away from the suction nozzle 6; the atomization core 2 and the guide part 1 are respectively arranged at one end of the liquid storage chamber 40 facing the base 5, the atomization core 2 is liquid-connected with the liquid storage chamber 40, and the guide part 1 is located on the side of the atomization core 2 away from the air outlet channel 30 in the first direction.

[0055] Specifically, the oil cup 4 has a liquid storage chamber 40 and an air outlet channel 30 arranged adjacent to each other in the transverse direction, and the oil cup 4 is provided with an assembly through hole for assembling the atomizer core 2 at one end of the liquid storage chamber 40 away from the suction nozzle 6, and a guide portion 1 arranged adjacent to the assembly through hole in the transverse direction. In the transverse direction, the guide portion 1 is arranged at one end of the assembly through hole away from the air outlet channel 30. The assembly through hole is connected to the liquid storage chamber 40, and the atomized liquid can flow from the liquid storage chamber 40 to the atomizer core 2 of the assembly through hole. The atomizer core 2 can conduct the atomized liquid, and the heating element 3 arranged on the heating surface 21 of the atomizer core 2 can connect the circuit to heat the atomized liquid to generate an aerosol. That is, an atomization channel extending in the transverse direction is defined between the assembly through hole and the base 5. In the transverse direction, the air inlet channel 20 is located at one end of the atomization channel 10 away from the air outlet channel 30. The suction nozzle 6 is assembled at one end of the oil cup 4 away from the base 5, and an opening is provided on the suction nozzle 6 to connect the air outlet channel 30 and the outside. The airflow and aerosol flowing in the air outlet channel 30 will eventually flow out of the outside through the opening of the suction nozzle 6. In addition, the electronic atomization device also includes a sealing member, which is assembled between the assembly through hole and the atomization core 2, and the sealing member can seal the gap between the oil cup 4 and the atomization core 2.

[0056] The external airflow flows in the air inlet channel 20 along the longitudinal direction, flows from the air inlet 201 to the air guide part 1, flows horizontally to the atomizer core 2 assembled in the assembly through hole, and takes the aerosol generated by the heating surface 21 of the atomizer core 2 away from the atomizer channel 10, flows to the air outlet channel 30, flows in the air outlet channel 30 along the longitudinal direction, and finally flows to the opening of the suction nozzle 6 for supplying to the user for inhalation or use.

In summary, the content of this specification should not be understood as a limitation on the utility model.
