It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

With reference to fig. 1 to 10, an embodiment of the present application provides an electronic cigarette, including:

cigarette rod 1 and atomization component 2, cigarette rod 1 includes the shell, slot 11 has on the shell, slot 11's bottom surface is provided with gas outlet 12, gas outlet 12 is skew along the first direction slot 11's bottom surface center, for example when slot 11's bottom surface is circular, the first direction can be the radial direction of arbitrary one of slot 11 bottom surface, and when perhaps slot 11's bottom surface was rectangular shape, the first direction can be the width direction of slot 11 bottom surface, perhaps length direction.

Referring to fig. 5, the atomizing assembly 2 includes a housing 21 and a lower base 22, the lower base 22 is connected to the housing 21 in a matching manner, an air inlet 23 is disposed on a bottom surface of the lower base 22, and the air inlet 23 is offset from a center of the bottom surface of the lower base 22 along the first direction; the atomization assembly 2 is in plug-in fit with the slot 11, so that the bottom surface of the slot 11 is opposite to the bottom surface of the lower base 22.

Under the condition that the atomization component 2 is in plug-in fit with the slot 11, the area of the air outlet 12 opposite to the air inlet 23 is directly related to the air inflow of the atomization component 2 in the electronic cigarette. When the atomization assembly 2 is located at the first insertion position, the area of the air outlet 12 opposite to the air inlet 23 is a first area, and the first area can be larger at this time, so that a larger flow of inlet air is provided for the atomization assembly 2; when the atomizing assembly 2 is in the second plugging position, the area of the air outlet 12 opposite to the air inlet 23 is a second area, and the second area is smaller than the first area, that is, when the atomizing assembly 2 is switched from the first plugging position to the second plugging position, the flow rate of the inlet air supplied to the atomizing assembly 2 is reduced; likewise, if it is desired to increase the flow of inlet air when the atomizing assembly 2 is in the second plugged position, the atomizing assembly 2 can be switched from the second plugged position to the first plugged position.

In particular, the switching of the atomizing assembly 2 between the first plugged position and the second plugged position can be achieved by the rotation of the atomizing assembly 2 relative to the cigarette rod 1. For example, when the bottom surfaces of the slot 11 and the lower base 22 are both in a bilaterally symmetric elongated structure, the insertion position of the atomizing assembly 2 can be switched by rotating the atomizing assembly 2 180 degrees relative to the cigarette rod 1.

The experience of a user smoking the electronic cigarette can be improved by switching the atomizing assembly 2 between the first plug-in position and the second plug-in position to adjust the air inflow of the atomizing assembly 2. For example, when the user wants to smoke the electronic cigarette with a relatively large force and in a hurry manner in some states, so as to obtain a feeling of full dribbling, the atomizing assembly 2 can be switched from the second insertion position to the first insertion position, so as to provide the atomizing assembly 2 with a relatively large flow of intake air, so as to meet the smoking requirement of the user; however, when the user wants to use the same electronic cigarette to slowly and leisurely smoke in another state, so as to obtain a feeling of carelessness, the atomization assembly 2 can be switched from the first plug-in position to the second plug-in position, and the flow rate of the air intake of the atomization assembly 2 is limited, so as to meet the smoking requirements of various users and users in different states. In addition, the plugging position of the atomizing assembly 2 may further include a plurality of plugging positions, for example, the plugging position of the atomizing assembly 2 with multiple gears is adjusted by the design of the bottom surface of the circular or regular polygonal slot 11 and the bottom surface of the lower base 22.

The electronic cigarette provided by the embodiment of the application comprises a cigarette rod 1 and an atomization component 2, wherein a slot 11 is formed in a shell of the cigarette rod 1, an air outlet 12 is formed in the bottom surface of the slot 11, the air outlet 12 deviates from the center of the bottom surface of the slot 11 along a first direction, an air inlet 23 is formed in the bottom surface of a lower base 22 of the atomization component 2, and the air inlet 23 deviates from the center of the bottom surface of the lower base 22 along the first direction; the atomization assembly 2 is in plug-in fit with the slot 11. And when the atomization assembly 2 is in the first plugging position, the area of the air outlet 12 opposite to the air inlet 23 is a first area; under the condition that atomization component 2 is in the second grafting position, the area that gas outlet 12 with air inlet 23 is relative is the second area, the second area is less than first area, gas outlet 12 with the area that air inlet 23 is relative with atomization component 2's air input directly is relevant in the electron cigarette. Through atomizing component 2 is in the switching between first grafting position and second grafting position, can be nimble atomizing component 2's inlet flow, and then realize the regulation to electron cigarette air input to satisfy different users ' suction demand, improve user's use and experience. Moreover, the atomizing assembly 2 is matched with the slot 11 in an inserting manner, so that the assembly process and the flow of the electronic cigarette can be optimized, and the use convenience of the electronic cigarette is improved.

Alternatively, with reference to fig. 5 and 6, with the atomizing assembly 2 in the first plugged position, the air outlet 12 is entirely opposite to the air inlet 23; referring to fig. 7 and 8, when the atomizing assembly 2 is in the second plugging position, a portion of the air outlet 12 is opposite to the air inlet 23, and the remaining portion of the air outlet 12 is opposite to the bottom surface of the lower base 22.

Specifically, the whole of the air outlet 12 is opposite to the air inlet 23, that is, the atomizing assembly 2 in the first inserting position can directly obtain the air flow output by the cigarette rod 1 from the air outlet 12, so as to ensure that the electronic cigarette can generate a larger atomizing amount, and meet the requirement of large-mouth suction of a user. And after the part of the air outlet 12 is opposite to the air inlet 23 and the remaining part of the air outlet 12 is opposite to the bottom surface of the lower base 22, the atomizing assembly 2 in the second plugging position can only directly obtain the airflow output by the cigarette rod 1 from the partial area of the air outlet 12, and the airflow in the remaining area of the air outlet 12 can be blocked by the bottom surface of the lower base 22 and then is substantially decelerated, so that the atomizing amount of the electronic cigarette is flexibly adjusted from the angle of reducing the air inlet flow of the atomizing assembly 2.

Optionally, referring to fig. 8 and 9, the air inlet 23 includes a first air inlet 231 and a second air inlet 232 which are sequentially communicated, the first air inlet 231 is close to the bottom surface of the slot 11, and the second air inlet 232 is far away from the bottom surface of the slot 11. The first and

second air inlets

231 and 232 may be engaged with the air outlet 12 by adjusting one of the first and

second air inlets

231 and 232 when the other is fixed.

The bottom surface of the lower base 22 may have a long bar shape, and the first direction may be a width direction of the bottom surface of the lower base 22, such that the first air inlet 231 covers a center of the bottom surface of the lower base 22. The two-stage air inlet structure formed by the first air inlet 231 and the second air inlet 232 can flexibly adjust the area of the air outlet 12 opposite to the air inlet 23 through the area and the deviation degree of the first air inlet 231.

In another specific embodiment, the first inlet 231 and the second inlet 232 may be coaxially disposed. For example, the first air inlet 231 and the second air inlet 232 are both offset from the center of the bottom surface of the lower base 22 along the first direction, so that the air flow entering the first air inlet 231 can flow to the second air inlet 232 in a balanced and effective manner, and the air inlet flow of the atomizing assembly 2 is ensured.

Alternatively, referring to fig. 9, the cross-sectional area of the first intake port 231 in the intake direction thereof is larger than the cross-sectional area of the second intake port 232 in the intake direction thereof.

Specifically, the air inlet direction of the first air inlet 231 may be along the axial direction of the atomizing assembly 2, i.e. the direction perpendicular to the paper in fig. 9, or may be a direction inclined at an angle with the axial direction of the atomizing assembly 2; the air inlet direction of the second air inlet 232 can also be along the axial direction of the atomizing assembly 2, i.e. the direction perpendicular to the paper in fig. 9, or the direction inclined at an angle with the axial direction of the atomizing assembly 2. When the cross-sectional area of the first air inlet 231 along the air inlet direction is larger than the cross-sectional area of the second air inlet 232 along the air inlet direction, the side wall of the first air inlet 231 and the side wall of the second air inlet 232 can be communicated to form a step-shaped air inlet, and the step surface of the step-shaped air inlet can block the air inlet flow of the atomizing assembly 2, so that the purpose of adjusting the air inlet flow of the atomizing assembly 2 is achieved.

Alternatively, the cross-sectional area of the first intake port 231 in the intake direction thereof is equal to the cross-sectional area of the second intake port 232 in the intake direction thereof.

Specifically, when the cross-sectional area of the first intake port 231 in the intake direction thereof is equal to the cross-sectional area of the second intake port 232 in the intake direction thereof, the first intake port 231 and the second intake port 232 may be coaxially disposed to form an intake passage in which the cross-sectional area in the intake direction is kept stable; the first air inlet 231 and the second air inlet 232 may be arranged in a staggered manner, the second air inlet 232 may still be held at the center of the bottom surface of the lower base 22, and the first air inlet 231 is offset from the center of the bottom surface of the lower base 22, so that when the atomization assembly 2 is switched between the second insertion position and the first insertion position, the relative area between the air outlet 12 and the air inlet 23 can be flexibly adjusted.

Alternatively, the first air inlet 231 may have a circular, elliptical, or oblong cross-section along the air intake direction thereof, and the second air inlet 232 may have a circular cross-section along the air intake direction thereof. When the second air inlet 232 is a circular air inlet, in order to ensure that the first air inlet 231 effectively admits air, a projection of the first air inlet 231 on the bottom surface of the lower base 22 may cover the second air inlet 232, specifically, a circular, elliptical or oblong projection of the first air inlet 231 may cover the second air inlet 232; the elliptical or oblong structure of the first air inlet 231 can avoid the air inlet area of the first air inlet 23 from being set too large on the basis of ensuring that the projection of the first air inlet 231 on the bottom surface of the lower base 22 covers the second air inlet 232, thereby ensuring the structural compactness of the lower base 22.
