The cross section of the housing 10 may be roughly rectangular, and the cross section of the housing 10 may include a length direction and a width direction.

A liquid storage chamber 13 may be formed inside the housing 10, and the liquid storage chamber 13 is located at the upper part of the housing 10, and the liquid storage chamber 13 can be used to accommodate a liquid medium. Specifically, in some embodiments, an atomizing chamber 12 is also provided in the housing 10, and the atomizing assembly 20 may be accommodated in the atomizing chamber 12. The atomizing chamber 12 may be located at the lower part of the housing 10. In some embodiments, an air flow channel 11 is further provided in the housing 10, and the air flow channel 11 is arranged on one side of the housing 10. Specifically, the air flow channel 11 may be located on one side of the atomizing chamber 12, and may be communicated with the atomizing chamber 12 for outputting the atomized gas after atomization. In some embodiments, the air flow channel 11 may be extended along the longitudinal direction of the housing 10. In some embodiments, an air outlet 15 is provided on the housing 10. Specifically, the air outlet 15 may be arranged at the top of the housing 10, and one end of the air flow channel 11 may be communicated with the air outlet 15 for delivering the atomized gas to the air outlet 15. In some embodiments, the atomizing chamber 12 further includes a closed area 121, which is an area arranged opposite to the air flow channel 11.

In some embodiments, the atomization assembly 20 may include an atomization surface 21. Specifically, the atomization surface 21 may be disposed on the porous body. The atomization surface 21 may be an end surface of the porous body and the heating element.

[0045] Further, in some embodiments, the base 30 may be located at the open end of the housing 10, for blocking the housing 10. In some embodiments, the base 30 may be integrally formed with the housing 10. Of course, it is understandable that in some other embodiments, the base 30 may not be limited to being integrally formed with the housing 10. In some embodiments, the atomizer may further include an air inlet 31, specifically, the air inlet 31 may be provided on the base 30, located in the middle of the base 30, specifically, may be provided through the base 30 along the thickness direction of the base 30. The air inlet 31 may be provided in communication with the atomizing chamber 12, so that an external airflow may enter the atomizing chamber 12, and then the atomized gas in the atomizing chamber 12 may be taken out.

[0046] Further, in some embodiments, the guide structure 40 may be disposed in the atomizing chamber 12, and disposed in the air inlet direction of the air inlet 31, and disposed close to the air flow channel 11. In some embodiments, the guide structure 40 may be located on one side of the central axis of the air inlet 31, and its protrusion may not exceed the central axis to avoid blocking the central airflow. The guide structure 40 may be used to guide the airflow entering the air inlet 31, directing part of the airflow to the closed area of ​​the atomizing chamber 12, thereby avoiding the accumulation of a large amount of high-temperature smoke in the closed area of ​​the atomizing chamber 12, avoiding the generation of condensate, and avoiding the risk of increased stray gas and burnt smell in the smoke due to plastic melting.

[0047] Further, in some embodiments, the flow guide structure 40 may be triangular, of course, it is understandable that in some other embodiments, the flow guide structure 40 may not be limited to a triangular shape. In some other embodiments, the flow guide structure 40 may be wedge-shaped or trapezoidal. In some embodiments, the size of the flow guide structure 40 may be smaller than the size of the atomizing chamber 12, so as to facilitate the flow of atomized gas into the air flow channel 11. In some embodiments, the flow guide structure 40 may be arranged between the atomizing assembly 20 and the air inlet 31, and a gap may be set between the flow guide structure 40 and the atomizing assembly 20, and the gap may form a connecting channel 14, and the connecting channel 14 is used to connect the atomizing chamber 12 and the air flow channel 11.

[0048] Further, in some embodiments, the guide structure 40 may include a guide surface 41, which is an inclined surface. The guide surface 41 may be arranged opposite to the air inlet 31 and may be arranged toward the closed area 121, and may be used to guide part of the airflow to the closed area 121 of the atomizing chamber 12, and may extrusion, speed up and guide the airflow output from the atomizing chamber 12 to the airflow channel 11.

[0049] Further, in some embodiments, the flow guide structure 40 may also include a flow surface 42, which may be arranged opposite to the atomizing surface 21. In some embodiments, the flow surface 42 may be a plane, and the flow surface 42 may form an angle with the flow guide surface 41, which may be equal to the set angle α. Of course, it can be understood that in some other embodiments, the flow surface 42 may not be limited to a plane. The interval between the flow surface 42 and the atomizing surface 21 may form the connecting channel 14. In some embodiments, the distance between the flow surface 42 and the atomizing surface 21 may be greater than zero and not greater than two-thirds of the height of the atomizing chamber 12. Specifically, in some embodiments, the distance between the flow surface 42 and the atomizing surface may be 1 / 3 to 2 / 3 of the height of the atomizing chamber.

[0050] Further, in some embodiments, two opposite sides of the guide structure 40 may extend to the side wall of the housing 10 along the width direction of the housing 10, and may be connected to the side wall. In some embodiments, the guide structure 40 may be integrally formed with the housing 10. Specifically, in some embodiments, the guide structure 40 may be integrally formed with the housing 10 by injection molding.

[0051] The airflow inside the atomizing chamber 12 of the electronic atomizing device of the present invention is significantly improved, the overall performance is significantly improved, and the smoke oil extraction effect is significantly improved.

[0052] like Figure 4 As shown, by comparing the velocity field of the atomizing gas of the electronic atomizing device of the present invention with the velocity field of the atomizing gas of the existing electronic atomizing device, after adding the guide structure 40, the velocity field inside the atomizing chamber 12 changes, and a part of the airflow entering from the air inlet 31 turns through the guide structure 40 and can be guided to the closed area 121 of the atomizing chamber 12.

[0053] like Figure 5 As shown, by comparing the outlet temperature of the atomized gas of the electronic atomization device of the present invention with the outlet temperature of the atomization gas of the existing electronic atomization device, firstly, the temperature of the atomized gas delivered from the air outlet 15 of the electronic atomization device of the present invention is 69°C, which is 4°C higher than the outlet temperature of the atomization gas of the existing electronic atomization device; secondly, the air flow temperature of the closed area 121 of the atomization chamber 12 of the electronic atomization device of the present invention is about 20°C lower than the air flow temperature of the closed area 121 of the existing electronic atomization device, and the high-temperature area of ​​the closed area 121 is also reduced; furthermore, after adding the guide structure 40, the heat exchange intensity between the airflow and the atomization surface 21 is increased, and the temperature distribution in the transition stage is also greatly improved compared with the existing electronic atomization device.

[0054] like Figure 6 As shown, by comparing the smoke oil concentration field in the atomization chamber of the electronic atomization device of the present invention with the smoke oil concentration field in the atomization chamber of the existing electronic atomization device, the smoke oil accumulation inside the atomization chamber 12 of the electronic atomization device of the present invention is significantly reduced. This is because after adding the guide structure 40, the airflow inside the atomization chamber 12 is transformed from turbulence to regularity, reducing the generation of vortices inside the atomization chamber 12. In the atomization chamber 12 of the electronic atomization device of the present invention, the amount of smoke oil carried by the turning section is significantly increased, and it presents a "downward" shape, reducing the contact with the wall surface of the turning section.

[0055] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
