Referring to fig. 1, 3 and 4 in combination, an atomizer provided in an embodiment of the present invention includes a liquid storage member 1, an atomizing assembly 2, a tubular connecting member 3 and an operating member 4, wherein a liquid storage chamber 13 for storing aerosol forming substrates is provided in the liquid storage member 1, and a smoking opening 14 is provided at the top of the liquid storage member 1. Referring to fig. 3, 5 and 12 in combination, in some embodiments, the liquid storage member 1 includes a housing 11 having a smoking opening 14 at the top and an opening at the bottom, and a base 12 mounted in the bottom opening of the housing 11, where the base 12 is provided with an air inlet 15 for introducing external air, and a portion of the housing 11 outside the tubular connection member 3 and the atomizing assembly 2 forms a liquid storage chamber 13.

Referring to fig. 5 and 6 in combination, at least a portion of the atomizing assembly 2 is accommodated in the liquid storage member 1, an atomizing cavity 24 for heating and atomizing the aerosol-forming substrate is formed in the atomizing assembly 2, and a liquid inlet 25 for selectively communicating the atomizing cavity 24 with the liquid storage cavity 13 is formed in the atomizing assembly 2. The atomizing assembly 2 is operable to heat the aerosol-forming substrate supplied from the reservoir 13 to the atomizing chamber 24 via the inlet 25 to atomize the aerosol-forming substrate to form a aerosol which is drawn by a user through the mouth 14 by the user's suction when the power supply 10 supplies power to the atomizer. Referring to fig. 6 and 12 in combination, in some embodiments, the atomizing assembly 2 includes a fixing member 21 fixed inside the liquid storage member 1, an atomizing tube 22 with a bottom end supported and fixed on the fixing member 21, and an atomizing core 23 for heating and atomizing aerosol-forming substrates, the inner cavity of the atomizing tube 22 forms an atomizing cavity 24, the sidewall of the atomizing tube 22 is provided with a liquid inlet 25, and the plugging sleeve 32 of the tubular connecting member 3 is axially movably sleeved on the atomizing tube 22. It will be appreciated that when the liquid storage member 1 includes the housing 11 and the base 12, the tubular connecting member 3, the fixing member 21 and the atomizing tube 22 are disposed in the housing 11, the fixing member 21 is supported and fixed on the base 12, and the portion of the housing 11 outside the tubular connecting member 3, the fixing member 21 and the atomizing tube 22 forms the liquid storage chamber 13. Referring to fig. 6 and 10 in combination, the holder 21 is provided with a through hole 211, at least a portion of the atomizing tube 22 is accommodated in and fixed to the through hole 211, and the atomizing core 23 is disposed in the atomizing chamber 24 and electrically connected to the power device 10. It is understood that the atomizing core 23 may be, but is not limited to, a ceramic atomizer having liquid absorbing capability or an atomizer with heating wires wrapped with liquid absorbing cotton.

Referring to fig. 3 and 7 in combination, the tubular connecting member 3 communicates the atomizing chamber 24 with the smoking opening 14, a first end of the tubular connecting member 3 is slidably disposed at the smoking opening 14, and a second end of the tubular connecting member 3 is axially movably disposed on the atomizing assembly 2. In this way, the smoke in the atomizing chamber 24 can be led out to the smoking opening 14 through the tubular connecting piece 3, and the tubular connecting piece 3 can be driven to move through the operating piece 4 to shield or expose the liquid inlet 25 on the atomizing assembly 2, so that the liquid inlet 25 on the atomizing assembly 2 is isolated from or communicated with the liquid storage chamber 13. That is, the user drives the tubular connecting piece 3 to move axially through the operating piece 4, so as to selectively cover or expose the liquid inlet 25 on the atomizing assembly 2, and further isolate or communicate the atomizing cavity 24 on the atomizing assembly 2 with the liquid storage cavity 13 of the liquid storage piece 1. When the liquid inlet 25 on the atomizing assembly 2 is shielded by the tubular connecting piece 3, the atomizing cavity 24 on the atomizing assembly 2 is in an isolated state with the liquid storage cavity 13 of the liquid storage piece 1, so that the contact between aerosol forming substrate and liquid-absorbing cotton and other parts of the atomizing core 23 is reduced and avoided, the liquid-cotton separation is realized, and the liquid leakage is prevented. When the liquid inlet 25 of the atomizing assembly 2 is exposed, i.e. in the case that the liquid inlet 25 of the atomizing assembly 2 is not shielded by the tubular connector 3, the aerosol-forming substrate in the liquid storage chamber 13 can enter the atomizing chamber 24 through the liquid inlet 25, so that the atomizing core 23 in the atomizing chamber 24 is heated and atomized to form the aerosol which can be inhaled by the user in the atomizing chamber 24.

Referring to fig. 2, 3 and 4, the operating member 4 is axially movably disposed through the smoking opening 14, and the operating member 4 is circumferentially rotatable in the smoking opening 14. When the operating member 4 is connected to the tubular connecting member 3, the operating member 4 is moved circumferentially to move the tubular connecting member 3 along a path between a first position where the liquid inlet 25 of the atomizing assembly 2 is shielded and a second position where the liquid inlet 25 of the atomizing assembly 2 is exposed. Specifically, the outer side wall of the operating piece 4 is convexly provided with a clamping part 5, the inner side wall of the tubular connecting piece 3 is provided with a clamping groove 6 for being matched with the clamping part 5 to be in clamping connection, the inner side wall of the tubular connecting piece 3 is concavely provided with a sliding groove 7 for guiding the clamping part 5 to be placed in or separated from the clamping groove 6, and the sliding groove 7 is communicated with the clamping groove 6. Referring to fig. 5, when the operating member 4 is rotated to the position where the holding portion 5 is staggered from the sliding groove 7, the holding portion 5 is locked in the locking groove 6, so that the operating member 4 can be locked with the tubular connecting member 3, and the tubular connecting member 3 can be driven to move between the first position where the liquid inlet 25 is covered and the second position where the liquid inlet 25 is exposed by pulling the operating member 4 upward or pushing the operating member 4 downward. When the operating member 4 is rotated to align the holding portion 5 with the sliding slot 7, the holding portion 5 is locked to disengage from the locking slot 6, so that the operating member 4 and the tubular connecting member 3 can be detached. That is, the operating member 4 can be pulled out from the smoking opening 14 when the atomizer is not in use, and stored separately from the tubular connecting member 3, so as to prevent the liquid inlet 25 from being opened by erroneous touching. When in secondary use, the operating piece 4 is only required to be inserted into the tubular connecting piece 3 through the smoking opening 14, the operating piece 4 is rotated to the clamping part 5 to be staggered with the sliding groove 7, the tubular connecting piece 3 can be driven to move through the operating piece 4 again, the secondary use of liquid core separation operation can be realized, and the purpose of reloading the drawing piece for recycling is achieved. It should be noted that the above-described situations in which the nebulizer is not in use include, but are not limited to, various possible situations during transportation, before the nebulizer is activated, and after the nebulizer is activated.

Compared with the prior art, when the operating piece 4 is rotated to the clamping part 5 and the sliding groove 7 are staggered, the operating piece 4 can be connected with the tubular connecting piece 3 in a buckling way, and the tubular connecting piece 3 can be driven to move between a first position for shielding the liquid inlet 25 and a second position for exposing the liquid inlet 25 through the operating piece 4, so that liquid core separation operation is realized. When the operation piece 4 is rotated to the position where the clamping part 5 is aligned with the sliding groove 7, the operation piece 4 can be separated from the tubular connection piece 3 and pulled out from the smoking opening 14, so that the liquid leakage caused by the misoperation of opening the liquid inlet 25 is avoided. When the device is used for the second time, the operating piece 4 is only needed to be reinserted into the tubular connecting piece 3 through the smoking opening 14, the operating piece 4 is rotated to the clamping part 5 to be staggered with the sliding groove 7, and the tubular connecting piece 3 is driven to move by the operating piece 4 to realize liquid core separation. Therefore, after the operating piece 4 is detached from the tubular connecting piece 3, the operating piece 4 can be reloaded for recycling, and then the operating piece 4 is axially moved to drive the tubular connecting piece 3 to move, so that the liquid inlet 25 on the atomizing assembly 2 can be repeatedly opened or closed for a plurality of times, and the repeated operation of liquid core separation is realized.

Referring to fig. 4, 8 and 9 in combination, in some of these embodiments, the operating member 4 may be, but is not limited to, a push-pull rod or a push-pull tube. Referring to fig. 7 and 8 in combination, when the operating member 4 is a push-pull rod or a push-pull tube, the clamping portion 5 is disposed adjacent to the first end of the push-pull rod or the push-pull tube, and the clamping slot 6 and the sliding slot 7 are disposed adjacent to the first end of the tubular connecting member 3, so that the push-pull rod or the push-pull tube is conveniently connected to or separated from the tubular connecting member 3 in a fastening manner. Referring to fig. 7 in combination, in some embodiments, the clamping groove 6 is an annular groove concavely formed on the inner side wall of the tubular connecting piece 3, and only the clamping portion 5 on the push-pull rod or push-pull tube is required to be aligned with the sliding groove 7 on the tubular connecting piece 3, after the clamping portion 5 is placed in the sliding groove 7, the push-pull rod or push-pull tube is rotated, so that when the clamping portion 5 on the push-pull rod or push-pull tube rotates to be staggered with the sliding groove 7, the clamping portion 5 on the push-pull rod or push-pull tube rotates into the annular groove, so that the clamping portion 5 can be axially abutted by the annular groove, and the operation piece 4 can be connected with the buckle of the tubular connecting piece 3. In this way, the push-pull rod or the push-pull tube is pushed or pulled axially by external force, so that the tubular connecting piece 3 can be driven to move axially. The push-pull rod or the push-pull pipe is reversely rotated until the clamping part 5 on the push-pull rod or the push-pull pipe is aligned with the chute 7 on the tubular connecting piece 3, the annular groove can release the axial abutting action of the clamping part 5, and the push-pull rod or the push-pull pipe can be pulled out of the tubular connecting piece 3 along the chute 7. It is understood that the operation member 4 in the embodiment of the present invention may be a silicone member, a rubber member, a plastic member, a metal member, or the like. Referring to fig. 8 in combination, in some embodiments, the clamping portion 5 is a protrusion with at least one side surface having an arc surface 51, so as to reduce the contact area between the clamping portion 5 and the groove wall of the annular groove, facilitate the rotation of the clamping portion 5 in the annular groove, and avoid the situation that the clamping portion 5 is stuck or dead due to a large friction between the clamping portion 5 and the groove wall of the annular groove. It can be understood that when the annular groove is an arc groove, the clamping portion 5 is a protrusion with at least one side surface being an arc surface 51, so that the protrusion with the arc surface 51 is adapted to the shape of the annular groove, and the clamping portion 5 can rotate in the annular groove conveniently.

In order to further enhance the balanced stability of the force, at least two holding portions 5 are provided at equal intervals in the circumferential direction of the operation member 4. Note that the holding portion 5 may be provided in one or a plurality of pieces. When the clamping parts 5 are arranged in a plurality, the clamping parts 5 are arranged at equal intervals along the circumferential direction of the operating piece 4, so that the balanced stability of stress is further enhanced.

The chute 7 and the clamping groove 6 are both arranged at one end of the vent pipe 31 far away from the plugging sleeve 32, the vent pipe 31 is driven to axially move through the operation piece 4, and then the vent pipe 31 drives the plugging sleeve 32 to move between the moving paths of exposing the liquid inlet 25 and shielding the liquid inlet 25, so that the liquid inlet 25 on the atomization assembly 2 is repeatedly opened or closed. In order to enhance the stability of the overall structure of the tubular connector 3, the vent tube 31 and the blocking sleeve 32 are integrally formed. Referring to fig. 6 in combination, in some embodiments, the inner diameter of the vent tube 31 is smaller than the inner diameter of the plugging sleeve 32 to form a step surface 33 at the junction of the vent tube 31 and the plugging sleeve 32. When the tubular connecting member 3 is moved to the first position where the liquid inlet 25 is shielded, the tip end surface of the atomizing tube 22 collides with the step surface 33.

Referring to fig. 6, 10 and 11, in some embodiments, the fixing member 21 is a silicone sealing seat, and a receiving groove 212 for receiving and positioning the plugging sleeve 32 is formed on the silicone sealing seat. Thus, since the plugging sleeve 32 is axially movably sleeved on the atomizing tube 22 of the atomizing assembly 2, when the tubular connecting piece 3 is positioned at the first position for shielding the liquid inlet 25 on the atomizing tube 22, the plugging sleeve 32 is at least partially accommodated and positioned in the accommodating groove 212, and the inner side wall of the accommodating groove 212 elastically abuts against the outer side wall of the plugging sleeve 32, so that the liquid leakage preventing performance is enhanced. In order to enhance the tightness, a first sealing ring 8 is provided at the junction of the sealing sleeve 32 and the atomizing tube 22. Furthermore, a first sealing groove 34 is provided on the sealing sleeve 32 or the atomizing tube 22, and the first sealing ring 8 is mounted in the first sealing groove 34.
