The extension portion 3120 is disposed through the through-hole 3501 and is used for limiting a travel of the atomizing portion 3110 into the atomizing tube 350, i.e., the atomizing portion 3110 can enter or leave the atomizing tube 350 along with displacement of the extension portion 3120.

Wherein the atomizing tube 350 is provided with two opposing through openings 3501 so that the second carrier 3102 can be inserted through the atomizing tube 350. In other embodiments, the number of positions of the through-hole 3501 is not limited to this embodiment. In some embodiments, the number of the through-holes 3501 may be 1 or more, for example, when the number of the through-holes 3501 is 1, at least one extending portion 3120 extending toward the through-holes 3501 extends from the atomizing portion 3110, and the extending portion 3120 is disposed through the through-holes 3501; if the through-holes 3501 are provided with 4 opposite through-holes, the atomizing portions 3110 may extend out of the extending portions 3120 facing the 4 through-holes 3501, so that the second carrier 3102 has a cross-shaped cross-section.

One end of the air duct 360 is nested with the atomizing tube 350.

The air duct 360 abuts against the second carrier 3102 to cooperate with the atomizing tube 350 to sandwich the second carrier 3102 therebetween.

In some embodiments, the inner diameter dimension of the air duct 360 is equal to or slightly larger than the outer diameter dimension of the atomizing tube 350, so that the end of the atomizing tube 350 where the through-opening 3501 is formed can be inserted into the air duct 360 until the air duct 360 abuts against the second carrier 3102.

Similarly, in embodiments of the present application, a through-opening 3501 may be provided on at least one of the atomizing tube 350 and the air duct 360 to cooperatively enable assembly of the second carrier 3102.

In some embodiments, the heating body 320 is partially or fully embedded in the inner wall of the atomizing tube 350 to improve the stability of the heating body 320. While the heating body 320 is exposed to the space inside the atomizing tube 350 to improve the heating efficiency of the heating body 320 to the atomized medium on the second carrier 3102. It is understood that the position of the heating body 320 is not limited thereto.

Alternatively, the heating body 320 is buried in the atomizing tube 350, i.e., the heating body 320 is not exposed to the inner and outer spaces of the atomizing tube 350.

In this embodiment, the heating body 320 has an arc heating surface, and the shape of the heating body is adapted to the wall of the atomizing tube 350, so that the heating body 320 can be attached to or embedded in the wall of the atomizing tube 350.

In other embodiments, heating body 320 may be other shapes. For example, the heating surface of the heating body 320 may be net-shaped and attached to or embedded in the wall of the atomizing tube 350; for another example, the heating surface of the heating body 320 may be arc-shaped and embedded in the atomizing tube 350 and the second carrier 3102. Similarly, a person skilled in the art may design the specific shape of the heating body 320 according to the actual situation, and is not particularly limited herein.

In this embodiment, the circuit board 330 is disposed at a distance from the atomizing tube 350. The heating body 320 is electrically connected to the circuit board 330 through a connection wire 340. The heating body 320 is an electric heating element, and may be an electric heating wire, a thermistor, a conductive paint, an electric heating film, etc. The connection wire 340 is integrally formed with the heating body 320 and connected to the circuit board 330, for achieving electrical connection between the heating body 320 and the circuit board 330. For example, the connection wires 340 are two pins of the heating body 320, and the connection wires 340 extend from one end of the heating body 320 to the circuit board 330 and are connected to the circuit board 330 to electrically connect the circuit board 330 and the heating body 320.

Wherein the connection wire 340 may be soldered to the soldering part 3301 of the circuit board 330. The solder 3301 may be a through hole or a blind hole provided on the circuit board 330. The welding is performed by heating the connecting wire 340 after it is inserted into the welding portion 3301, which is advantageous in improving welding efficiency.

In other embodiments, the connection wires 340 may be connected to the circuit board 330 by conductive adhesive bonding or the like. In addition, the connection wire 340 may be a wire connected between the heating body 320 and the circuit board 330.

In this embodiment, the atomizer 10 may utilize the cooperation of the atomizing tube 350 and the stopper 370 to achieve the limitation of the connection wire 340.

The limiting piece 370 is embedded at one end of the atomizing pipe 350, and the connecting wire 340 in the atomizing pipe 350 is clamped between two adjacent limiting convex teeth 3701 and the pipe wall of the atomizing pipe 350, so that the limiting of the connecting wire 340 is realized.

Wherein the connecting wire 340 may be partially thickened. The thickened portion of the connecting wire 340 may be disposed in an interference fit between adjacent spacing lugs 3701 and the wall of the atomizing tube 350.

It is understood that when the connection wire 340 is completely located outside the atomizing tube 350, the limiting member 370 may be sleeved on the atomizing tube 350 to cooperate with the atomizing tube 350 to limit the connection wire 340. For example, the spacing teeth 3701 may be disposed on an inner side of the spacing member 370 such that adjacent spacing teeth 3701 may engage the outer wall of the atomizing tube 350 to capture the connecting wire 340.

Of course, the limiting of the connecting wire 340 may be achieved by other manners, for example, a protrusion or a groove for clamping the connecting wire 340 is provided on the wall surface of the atomizing tube 350, and for example, a limiting member 370 is provided with a limiting through hole through which the connecting wire 340 passes, and so on.

In other embodiments, the heating body 320 may also be electrically connected to the circuit board 330 through other conductive structures, such as conductive posts, outside the connection wires 340.

In some embodiments, there is a gap between the atomizing portion 3110 and the atomizing tube 350 so that a portion of the aerosol may enter the first gas passage 302 and be delivered to the suction hole 101 through the second gas passage 304.

The second carrier 3102 may be embedded in the first carrier 3101, i.e., the extension 3120 is clamped in the space of the first carrier 3101. Further, the extension portion 3120 may be disposed in the gap of the first carrier 3101 in an interference manner, so as to increase the contact area between the extension portion 3120 and the first carrier 3101, and improve the efficiency of conducting the atomized medium on the first carrier 3101 to the extension portion 3120. Of course, the extension 3120 may only partially abut the first carrier 3101 to facilitate assembly or disassembly.

It is understood that in some embodiments, the structure of the carrier container 400 may be different from that of the present embodiment, and the structural designs of the first sealing member 420 and the second sealing member 430 may be applied to the carrier container 400, or may be applied to other components outside the carrier container 400.

Referring to fig. 13 in combination, fig. 13 is a schematic structural diagram of a second cover according to some embodiments of the present disclosure.

In this embodiment, the atomizing housing 100 has a first bottom wall 140. Specifically, the second cover 120 of the atomizing housing 100 has a groove for forming the first accommodating cavity 102 in cooperation with the first cover 110, and the first bottom wall 140 is a bottom wall of the groove. The circuit board 330 is disposed between the first bottom wall 140 and the first seal 420.

The second cover 120 is provided with a first electrode holder 1202 and a second limiting portion 1203. The first electrode holder 1202 is used for receiving the circuit board 330. The second limiting portion 1203 may cooperate with the first limiting portion 4201 to limit the circuit board 330.

Specifically, the first electrode holder 1202 is a protruding holder protruding on the first bottom wall 140, and has an electrode via 107. The circuit board 330 is placed on the first electrode holder 1202 and is partially exposed outside the atomizing housing 100 through the electrode via 107. When the host 20 is docked with the atomizer 10, the electrode terminals 630 can abut against the circuit board 330 through the electrode vias 107 to achieve electrical connection, thereby supplying power to the circuit board 330.

In some embodiments, the circuit board 330 may also be disposed on a side of the first bottom wall 140 facing the main body 20, where the circuit board 330 is entirely exposed outside the atomizing housing 100.

The second limiting portion 1203 is protruding on the surface of the second cover 120 and surrounds the first electrode holder 1202, and the protruding height of the second limiting portion 1203 is greater than the protruding height of the first electrode holder 1202. The second limiting portion 1203 is adapted to the circuit board 330 in shape, so as to enclose an area where the circuit board 330 can be placed exactly, and facilitate assembly of the circuit board 330. When the circuit board 330 is placed on the first electrode holder 1202, it may just abut against the second limiting portion 1203, or may be disposed at an interval with the second limiting portion 1203.

The first stopper 4201 is also designed to be adapted to the shape of the circuit board 330. The bottom wall of the second protruding portion 4220 may abut against the top wall of the second limiting portion 1203, at this time, the circuit board 330 just abuts against the surface of the first sealing member 420 provided with the second protruding portion 4220, and meanwhile, the side wall of the first protruding portion 4210 is attached to the side wall of the second limiting portion 1203, that is, the first limiting portion 4201 is in clamping connection with the second limiting portion 1203.

The thickness of the circuit board 330 is exactly equal to the sum of the protrusion height of the second protrusion 4220 and the protrusion height difference between the second limiting portion 1203 and the first electrode base 1202, so that the circuit board 330 can be exactly abutted against the surface of the first sealing member 420 provided with the second protrusion 4220. Of course, the thickness of the circuit board 330 may be slightly greater than the sum of the two.

In addition, condensate droplets may form after the nebulized medium is nebulized into an aerosol. To avoid condensation from dripping onto the components, a liquid storage tank 1204 is disposed on a side of the first bottom wall 140 adjacent to the first sealing member 420. The reservoir 1204 is disposed opposite the first seal 420, and a projection of the reservoir 1204 onto the first seal 420 covers the first through hole 104 to receive condensate dripping from the first through hole 104.

Further, the liquid storage groove 1204 is partially located in the area surrounded by the second limiting portion 1203, and partially extends to the outside of the area. The second limiting portion 1203 has a liquid guiding port 1205 communicated with the liquid storage tank 1204, and condensate in the liquid storage tank 1204 can flow out of an area enclosed by the second limiting portion 1203 through the liquid guiding port 1205. The fluid port 1205 may also facilitate access to the discharge circuit board 330.

The second cover 120 is further provided with an air inlet seat 1206. The air inlet 1206 is a protruding seat protruding on the first bottom wall 140, and the protruding height thereof is smaller than that of the first electrode 1202. The second air intake hole 103 is located in the air intake seat 1206 and penetrates the first bottom wall 140.

To avoid condensation from falling into the second intake aperture 103, the intake seat 1206 is adjacent to or spaced apart from the reservoir 1204. In the present embodiment, the air intake seat 1206 is adjacent to the liquid storage tank 1204, and a portion of the air intake seat 1206 forms a portion of a side wall of the liquid storage tank 1204.

Referring to fig. 14 in combination, fig. 14 is a schematic view illustrating an assembly structure of a second cover and a circuit board according to some embodiments of the present disclosure.

In the present embodiment, the circuit board 330 is located on a side of the first sealing member 420 facing away from the second sealing member 430, and is disposed on the first electrode holder 1202. To prevent condensation droplets from falling onto the circuit board 330, the circuit board 330 has a fourth through hole 3302. The fourth through hole 3302 is disposed coaxially with the first through hole 104, and the aperture of the fourth through hole 3302 is not smaller than the aperture of the first through hole 104, so as to avoid condensate from dropping from the first through hole 104 onto the circuit board 330. That is, condensate passing through the first through hole 104 can pass through the fourth through hole 3302 and enter the reservoir 1204. In addition, the fourth through hole 3302 also serves as a ventilation hole, and is respectively communicated with the first through hole 104 and the second air inlet hole 103.

Further, the liquid absorbing member 520 of the atomizer 10 is disposed on the first bottom wall 140 and surrounds the periphery of the liquid storage tank 1204. Wherein the liquid absorbing member 520 has a guide portion 5201 protruding into the liquid storage tank 1204, the guide portion 5201 being for absorbing condensate in the liquid storage tank 1204. Wherein the liquid absorbing member 520 is laid on the first bottom wall 140. The guide portion 5201 extends into the liquid storage groove 1204 through the liquid guide port 1205 to absorb condensate, so that the liquid absorbing member 520 can cooperate with the liquid storage groove 1204 to form a condensate storage mechanism.

Referring to fig. 15 in combination, fig. 15 is a schematic view of a portion of a host according to some embodiments of the present application.

To avoid condensate from contacting the circuit board 330 on the first electrode holder 1202, the air intake holder 1206 is designed to have a protrusion height smaller than that of the first electrode holder 1202, so that condensate can drop onto the second bottom wall 240 of the lower main casing 200 through the second air intake hole 103 when the condensate is excessively accumulated. Wherein, a receiving groove 2101 is arranged on a side of the base 210 of the main casing 200 facing the second cover 120 for receiving dropped condensate, and the second bottom wall 240 is a bottom wall of the receiving groove 2101.

The second bottom wall 240 is provided with a second electrode seat 2102. The second electrode mount 2102 has a through hole similar to the electrode via 107 so that the electrode terminal 630 can pass through the second electrode mount 2102 on the second bottom wall 240. When the atomizer 10 is docked with the host 20, one end of the electrode terminal 630 penetrates through the second bottom wall 240 and abuts against the circuit board 330 disposed on the first bottom wall 140.

The second bottom wall 240 is further provided with an air outlet seat 2103. The outlet hole 206 is located in the outlet seat 2103 and penetrates the second bottom wall 240. To prevent condensate from dripping from the second air inlet 103 from passing through the air outlet 206, the projection of the air outlet 2103 on the second cover 120 is spaced apart from the air inlet 1206.
