[0010] Further, along the second direction, a ratio of a size W1 of the air intake structure to a size W3 of the heating area of the heating element is 0.5-1.5.
[0011] Further, along the second direction, a size W1 of the air intake structure is equal to a size W3 of a heating area of the heating element.
[0012] Further, the air inlet channel, the atomization channel and the air outlet channel are sequentially connected along the first direction, and the air inlet channel and the air outlet channel extend in a longitudinal direction perpendicular to the first direction and the second direction.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0030] See also Figure 1-4 The embodiment of the utility model provides an electronic atomization device, which has an air inlet channel 20, an atomization channel 10 and an air outlet channel 30 connected in sequence; the electronic atomization device also includes an atomization core 2 arranged in the atomization channel 10, and a guide part 1 arranged between the air inlet channel 20 and the atomization core 2; wherein the atomization core 2 includes a heating surface 21 and a heating body 3 arranged on the heating surface 21; the heating surface 21 has a first direction parallel to the air flow direction in the atomization channel 10 and a second direction perpendicular to the first direction; the guide part 1 has a guide surface 11 inclined from the air inlet channel 20 to the heating surface 21, and a plurality of guide grooves 112 arranged at intervals along the second direction are provided on the guide surface 11, and each guide groove 112 extends from the air inlet channel 20 to the heating surface 21.
[0031] In the embodiment of the utility model, the atomized liquid infiltrates the atomizing core 2, and is heated by the heating element 3 on the heating surface 21 to generate high-temperature aerosol. The external airflow can flow to each guide groove 112 through the air inlet 201 of the air inlet channel 20, and the airflow is guided by the guide groove 112 to flow to the atomizing channel 10 and take the aerosol away from the atomizing channel 10, and finally take it out to the outside through the air outlet channel 30. By providing the inclined guide surface 11, the airflow flows relatively smoothly to the heating surface 21, thereby reducing the turbulence formed by the airflow vertically impacting the heating surface 21. In addition, a plurality of guide grooves 112 are provided on the guide surface 11, and the plurality of guide grooves 112 are arranged at intervals along the second direction of the heating surface 21. Therefore, the airflow can cover most of the heating area of the heating surface 21. At the same time, the flow rate of the airflow can be accelerated in each guide groove 112, and the airflow can be guided more evenly in the second direction. When the faster and more even airflow flows to the heating area of the heating surface 21, more aerosol can be brought to the air outlet channel 30, thereby improving the atomization amount and atomization effect.
[0032] 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 2 The 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.
[0033] Furthermore, a plurality of partitions 111 arranged at intervals along the second direction and extending along the first direction are provided on the guide surface 11 , and a guide groove 112 is formed between two adjacent partitions 111 .
[0034] Specifically, a plurality of partitions 111 are arranged at intervals along the second direction and all protrude from the guide surface 11. The extension direction of each partition 111 is parallel to the flow direction of the airflow in the guide groove 112, and a guide groove 112 can be formed between two partitions 111. When the airflow flows from the air inlet channel 20 to the guide part 1, the airflow will enter each guide groove 112. In the same guide groove 112, the partitions 111 on both sides can compress the airflow to accelerate the airflow velocity. At the same time, through the limiting effect of the two side walls, the airflow can be prevented from being too dispersed, so that the airflow is guided more evenly in the second direction, so that the airflow can better bring the aerosol out of the heating area of the heating surface 21, thereby improving the atomization amount and atomization effect.
[0035] For further information, see Figure 4The air inlet channel 20 includes an air inlet structure connected to the atomization channel 10, and a dimension W1 of the air inlet structure extending along the second direction is greater than a dimension W2 extending along the first direction.
[0036] Specifically, the airflow of the air inlet channel 20 flows to the guide part 1 through the air inlet structure. By setting the air inlet structure to extend along the second direction, and the dimension W1 of the air inlet structure extending along the second direction is larger than the dimension W2 extending along the first direction, the air inlet structure has a larger airflow coverage area along the second direction of the heating surface 21, so that the airflow flowing from the air inlet structure to the guide part 1 and then to the heating surface 21 can contact with most of the aerosol generated in the heating area, and then can take away most of the aerosol, thereby improving the atomization amount and atomization effect.
[0037] Furthermore, the air intake structure includes a plurality of air intake ports 201 arranged at intervals along the second direction, and the air intake ports 201 correspond to the guide grooves 112 one by one.
[0038] Specifically, the air intake structure includes a plurality of air intake ports 201, and each air intake port 201 is arranged at intervals along the second direction and corresponds one-to-one with the guide groove 112. Compared with the air intake method in which the air intake structure is a single air intake port 201, when the air intake structure has the same size, the air intake structure includes a plurality of air intake ports 201, which can increase the flow rate of the airflow. In addition, the air intake ports 201 correspond one-to-one with the guide groove 112, so after the airflow flows out from each air intake port 201, it can directly flow to the corresponding guide groove 112, which can avoid the airflow from the air intake port 201 vertically impacting the heating surface 21 and causing turbulence, and can also speed up the airflow speed, making the airflow more uniform, thereby further improving the atomization amount and atomization effect.
[0039] For further information, see Figure 4 , a dimension W10 of the air inlet 201 extending along the second direction is greater than or equal to a dimension W20 extending along the first direction.
[0040] In some embodiments, the dimension W10 of each air inlet 201 extending along the second direction may be greater than the dimension W20 extending along the first direction. Specifically, the air inlet 201 may be elliptical or track-shaped, etc. In some embodiments, the dimension W10 of the air inlet 201 extending along the second direction may be equal to the dimension W20 extending along the first direction, and specifically, the air inlet 201 may be circular, etc.
[0041] Since the air intake structure includes a plurality of air intakes 201 arranged at intervals along the second direction, the dimension W2 of the air intake structure extending along the first direction is the dimension W20 of a single air intake 201 extending along the first direction; the dimension W1 of the air intake structure extending along the second direction is the sum of the total dimension of the plurality of air intakes 201 extending along the second direction and the spacing between two adjacent air intakes 201. It can be understood that the distance between two adjacent air intakes 201 is small and can be ignored. Therefore, the dimension W1 that affects the extension of the air intake structure along the second direction includes the number of air intakes 201 and the dimension W10 of a single air intake 201 extending along the second direction. The air intake structure can be extended to the second direction and the airflow speed can be accelerated by changing the number of air intakes 201 or changing the dimension W10 of the air intake 201 extending along the second direction.
[0042] In addition, for the same electronic atomization device, the shapes of the multiple air inlets 201 can be the same, so the preparation process can be simplified, and the amount of gas flowing out of each air inlet 201 can be the same, so that the gas flowing to the flow guide part 1 is more uniform. It can be understood that in some embodiments, the shapes of the multiple air inlets 201 of the same electronic atomization device can be different.
[0043] For further information, see Figure 1 The air flow area of the air intake passage 20 gradually decreases toward the air intake port 201 .
[0044] Specifically, in the lateral direction, the air inlet channel 20 is composed of a plurality of sub-air inlet channels, and each sub-air inlet channel corresponds to an air inlet port 201. In the longitudinal direction, the air flow area of each sub-air inlet channel gradually decreases from the end away from the air inlet port 201 toward the air inlet port 201, so that the air flow area of the air inlet channel 20 gradually decreases in the direction of the air inlet port 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, in the process of the air flow flowing in the air inlet channel 20, the flow rate of the air flow gradually increases until the air flow reaches the air inlet port 201, and 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.
[0045] For further information, see Figure 1 , along the second direction, the ratio of the size W1 of the air intake structure to the size W3 of the heating area of the heating element 3 is 0.5-1.5.
[0046] Specifically, along the second direction, the ratio of the size W1 of the air inlet structure to the size W3 of the heating area of the heating element 3 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 size W1 of the air inlet structure along the second direction to the size W3 of the heating area of the heating element 3 along the second direction 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.
[0047] It is worth noting that since the air inlets 201 of the air intake structure correspond one to one with the guide grooves 112 of the guide portion 1, the dimension W1 of the air intake structure along the second direction is equivalent to the sum of the dimensions of the guide grooves 112 on the guide portion 1 along the second direction, that is, the ratio of the sum of the dimensions of the guide grooves 112 on the guide portion 1 along the second direction to the dimension W3 of the heating area of the heating element 3 can be 0.5-1.5.
[0048] For further information, see Figure 1 , along the second direction, the size W1 of the air intake structure is equal to the size W3 of the heating area of the heating element 3 .
[0049] In some specific embodiments, the air intake structure includes multiple air intake ports 201, and the dimension W1 of the air intake structure along the second direction is equivalent to the sum of the dimensions of each guide groove 112 on the guide portion 1 along the second direction, and is equal to the dimension W3 of the heating area of the heating element 3, thereby ensuring the flow rate of the airflow when flowing out from the air intake port 201; at the same time, the airflow flowing out from the air intake port 201 can just cover the area of the corresponding guide groove 112 in the second direction, and the airflow will not disperse in the guide groove 112 when flowing in the guide groove 112; and the airflow after passing through the guide groove 112 can completely cover the heating area of the heating element 3 in the second direction, and can bring out most of the aerosol, thereby increasing the atomization amount and atomization effect.
[0050] For further information, see Figure 2 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.
[0051] 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.
[0052] Furthermore, in some specific embodiments, the electronic atomization device also includes a suction nozzle 6, an oil cup 4 and a battery rod 7 connected to one end of the suction nozzle 6 and arranged in a transverse direction, and a base 5 connected to the end of the oil cup 4 away from the suction nozzle 6 and arranged in a transverse direction with the battery rod 7, wherein the oil cup 4 has a liquid storage chamber 40 and an air outlet channel 30 arranged in 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 provided with one end of the liquid storage chamber 40 facing the base 5, the atomization core 2 is in liquid communication 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.
[0053] 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 10 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. In addition, the whole formed by the oil cup 4 and the base 5 is arranged transversely with the battery rod 7, and the suction nozzle 6 is assembled at the same end of the oil cup 4 and the battery rod 7 in the longitudinal direction. The suction nozzle 6 is provided with an opening connecting the air outlet channel 30 and the outside, and 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.
[0054] 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.
