Specifically, the atomization mechanism includes a housing assembly and an atomization assembly located within the housing assembly. The housing assembly includes a hollow tubular housing, a rotating sleeve 112 and an adjusting ring 113 .

The housing has a receiving cavity for accommodating the atomizing assembly. In the illustrated embodiment, the housing is a hollow cylindrical tube. It can be understood that in other embodiments, the shape of the housing is not particularly limited. For example, the part corresponding to the adjustment ring 113 is cylindrical, and other parts may be in other shapes. The part corresponding to the adjustment ring 113 is arranged in a cylindrical shape to facilitate the rotation of the rotating sleeve 112 around the housing.

In some embodiments, the housing includes a first tube body 114 and a second tube body 115 , and the second tube body 115 is connected to the first tube body 114 . In the illustrated embodiment, the first tube body 114 is inserted into the second tube body 115 and is fixedly connected to the second tube body 115 . It can be understood that in other embodiments, the second tube body 115 can also be inserted into the first tube body 114 and fixedly connected to the first tube body 114 . It should be noted that in this article, if there is no special explanation, "fixed connection" is the abbreviation of "fixed connection", and the method of fixing is not particularly limited. It can be a detachable fixed connection, such as screw connection, snap connection, etc., or It can be a non-detachable fixed connection, such as bonding, welding, riveting, etc. In addition, when two elements are described as connected, they can be directly connected or indirectly connected through an intermediary. It can be an internal connection between the two elements or an interactive relationship between the two elements. In some embodiments, the first tube body 114 and the second tube body 115 are integrally formed. In other embodiments, the first tube body 114 and the second tube body 115 are detachably and fixedly connected.

In some embodiments, the first tube 114 has a liquid reservoir 114a for storing liquid. Optionally, the liquid storage tank 114a is located in the first tube body 114 and is integrally formed with the tube wall of the first tube body 114. It can be understood that in other embodiments, the liquid storage tank 114a can also be independent of the first tube body 114. The second tube body 115 is provided with an air inlet hole 115a. In the illustrated embodiment, the air inlet hole 115a is close to the connection between the first tube body 114 and the second tube body 115; the air inlet hole 115a is triangular. It can be understood that in other embodiments, the position of the air inlet hole 115a is not limited to being close to the connection between the first tube body 114 and the second tube body 115, and can also be adjusted according to specific circumstances; the shape of the air inlet hole 115a can also be Not limited to triangles, but can also be other shapes, such as circles, rectangles, etc.

The rotating sleeve 112 is set on the housing, and the rotating sleeve 112 can move relative to the housing. Optionally, the rotating sleeve 112 can rotate around and move in the axial direction of the housing. It can be understood that the axial direction refers to the direction in which the central axis of the object is located. In Figure 2, the axial direction of the housing refers to the direction represented by Z; the direction around the axial direction of the housing refers to the circumferential direction of the housing, that is, the direction represented by X in Figure 2. In addition, the rotating sleeve 112 can also rotate along the axial direction of the housing (360° rotation), which makes the above-mentioned atomizer 10 have a higher user experience.

In some embodiments, the outer surface of the rotating sleeve 112 is also provided with a plurality of spaced resistance-increasing grooves 112 a , and the plurality of resistance-increasing grooves 112 a are arranged along the circumferential direction of the rotating sleeve 112 . By arranging a plurality of spaced resistance-increasing grooves 112a on the outer surface of the rotating sleeve 112, the friction force when twisting the rotating sleeve 112 can be increased, making it easier to twist the rotating sleeve 112. In the embodiment in the figure, a plurality of resistance-increasing grooves 112a are arranged in a row at intervals along the circumferential direction of the rotating sleeve 112 .

In the illustrated embodiment, adjust The node ring 113 is sleeved on the first tube body 114 and is located between the first tube body 114 and the rotating sleeve 112 . It can be understood that in other embodiments, the adjustment ring 113 is not limited to being sleeved on the first tube body 114, but can also be at other positions, and the specific position only needs to correspond to the air inlet hole 115a. For example, when the air inlet hole 115a is provided at an end of the second tube body 115 away from the first tube body 114, the adjustment ring 113 is sleeved on the second tube body 115, making it easier to adjust the air inlet hole 115a.

In some embodiments, the adjusting ring 113 is fixed in the rotating sleeve 112 and contacts and cooperates with the housing. The adjusting ring 113 can be driven by the rotating sleeve 112 to approach or move away from the air inlet 115a to at least partially block the air inlet 115a. That is, the amount of air intake is controlled by blocking the area of the air inlet hole 115a by the adjustment ring 113. In some embodiments, when the adjustment ring 113 moves upward or downward to a certain position along the axis of the housing, it can also completely cover or not completely cover the air inlet hole 115a. Of course, the adjustment ring 113 is in contact with the housing to more effectively adjust the effective air intake amount of the air inlet hole 115a. In some embodiments, the adjustment ring 113 is an elastic adjustment ring 113 . By arranging the adjusting ring 113 as an elastic adjusting ring 113, the adjusting ring 113 is conveniently close to the housing. Of course, in some embodiments, the adjustment ring 113 need not be snug against the housing.

In some embodiments, the inner wall of the rotating sleeve 112 is provided with a slot, and the adjustment ring 113 is located in the slot. Furthermore, reinforcements are provided on the inner wall of the rotating sleeve 112 . The reinforcement is close to the card slot and used to prevent the adjustment ring 113 from sliding out of the card slot.

In some embodiments, there is a gap 116 between the inner wall of the rotating sleeve 112 and the first tube body 114, and the gap 116 is connected to the air inlet hole 115a. In the illustrated embodiment, the gap 116 includes an upper air inlet 116a and a lower air inlet 116b; wherein, the inner wall of the proximal end of the rotating sleeve 112 and the first tube body 114 form an upper air inlet 116a, and the rotating sleeve 112 The inner wall of the distal end is enclosed with the first tube body 114 to form a lower air inlet 116b, and both the upper air inlet 116a and the lower air inlet 116b are connected with the air inlet 115a. Through this arrangement, external air can enter the housing assembly from both ends of the rotating sleeve 112 . Of course, such an arrangement can also make the movement of the rotating sleeve 112 in the axial direction of the housing easier. It can be understood that in some embodiments, one end of the rotating sleeve 112 and the first pipe 114 may be enclosed to form a channel for external air to enter the air inlet 115a. It should be noted that the proximal end of the rotating sleeve 112 refers to the end of the atomizer 10 including the housing assembly that is close to the user when in use, and the distal end of the rotating sleeve 112 refers to the end of the atomizer 10 including the housing assembly that is in use. away from the user.

Capacity. Since the first limiting groove 114b is an annular groove, the first protrusion 112b can also be in the first limiting groove 114b. Internal rotation makes the rotating sleeve 112 more stable when rotating around the axial direction of the housing, and is less likely to move upward or downward during rotation. In some embodiments, there are three first protrusions 112b, and the three first protrusions 112b can be located in one first limiting groove 114b at the same time. By providing three first protrusions 112b, the cooperation between the first protrusions 112b and the first limiting groove 114b can be stabilized. It can be understood that in other embodiments, the number of first protrusions 112b is not limited to three, but may also be multiple (two or any integer greater than three). Of course, it can also be one. In the illustrated embodiment, the number of first limiting grooves 114b is two. It can be understood that in other embodiments, the number of first limiting grooves 114b is not limited to two, and can also be other integers greater than 2, and the specific selection can be adjusted according to the actual situation.

In other embodiments, there are a plurality of second limiting grooves on the rotating sleeve 112, and the plurality of second limiting grooves are spaced along the axial direction of the rotating sleeve 112, and the second limiting grooves are annular grooves; the first tube The body 114 is provided with a second protrusion. By moving the rotating sleeve 112 along the axial direction of the first tube body 114, the second protrusion can move from one of the second limiting grooves to the other second limiting groove ( For example, within the adjacent second limiting groove), so that the adjustment ring 113 partially covers, completely covers, or does not cover the air inlet 115a at all.

Specifically, there is an air intake channel between the air inlet and the air inlet hole 115a. When there is air flow passing through the air flow sensor 129, the air flow sensor 129 feeds back the air flow signal it feels to the controller to open the working circuit of the atomization core 121; when there is no air flow, the air flow sensor 129 feeds back the air flow signal it feels to the controller. , to close the working circuit of the atomizer core 121. It should be noted that the "with air flow" in the above "there is air flow passing through the sensor" means that the air flow is above a predetermined value; the "no air flow" in the above "when there is no air flow" means that there is no air flow or the air flow is low. at default value.

The air flow enters the atomizer 10 from the air inlet hole 115a, and passes through the air inlet channel and the air inlet. The aerosol enters the atomization chamber 125, causing the aerosol in the atomization chamber 125 to be sucked out from the air outlet channel 114c. When it is necessary to adjust the effective air intake amount of the air inlet hole 115a, the rotating sleeve 112 is moved upward or downward, so that the area of the adjustment ring 113 covering the air inlet hole 115a changes, thereby adjusting the effective air intake amount of the air inlet hole 115a. . For example, in the state shown in Figure 5, the adjustment ring 113 blocks part of the air inlet hole 115a. At this time, the air intake volume is small and the suction resistance is large, and it can be used as an oral suction mode. When the adjustment ring 113 is moved downward, the state shown in Figure 6 is presented, and the air inlet hole 115a is fully opened. At this time, the air intake volume becomes larger and the suction resistance is smaller, which can be used as the lung suction mode. In addition, it can be understood that in the atomizer 10 provided with an air flow sensor, after the air flow enters the air inlet channel, the air flow sensor feeds back the air flow signal, thereby opening the working circuit of the atomization core 121 and causing the atomization core 121 to atomize the liquid to produce Aerosol. Can It is understood that in an atomizer 10 without an airflow sensor, the opening and closing of the atomizing core 121 can be controlled directly through a switch.
