The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

Referring to fig. 1 and 2, in one embodiment, the atomizing assembly 10 includes: the housing 20, the atomizing base 30, the atomizing element 40 and the stopper 50. A reservoir chamber 21 for storing liquid is provided inside the housing 20, and an air flow passage 22 is provided therethrough. The atomizing base 30 is fixedly connected with the housing 20, the liquid storage cavity 21 is sealed, and a liquid inlet 31 communicated with the liquid storage cavity 21 is formed in the atomizing base 30. The atomizing element 40 is arranged in the atomizing base 30, liquid in the liquid storage cavity 21 can enter the atomizing element 40 through the liquid inlet 31, and external air flow can flow into the air flow channel 22 through the atomizing element 40. The atomizing element 40 atomizes the liquid into the aerosol passage 22 with the external airflow, and the aerosol is output from the aerosol passage 22 and is inhaled by the user. The stopper 50 is movably disposed on the atomizing base 30 and can block or open the liquid inlet 31.

The atomization assembly 10 can slide close to the atomization seat 30 through the stopper 50, and the liquid inlet 31 on the atomization seat 30 is blocked through the stopper 50, so as to prevent the atomization assembly 10 from leaking during storage and transportation. When the atomizing assembly 10 is used, the stopper 50 can slide away from the atomizing base 30, so that the liquid inlet 31 is opened by the stopper 50, the liquid in the liquid storage cavity 21 enters the atomizing element 40 from the liquid inlet 31 for atomization, and the mist generated by atomization flows out from the air flow channel 22. The liquid in the liquid storage cavity 21 can be tobacco tar or other liquid, and can be selected according to the requirement.

Referring to fig. 3 and 4, in order to make the stopper 50 slide more smoothly toward or away from the atomizing base 30, a sliding groove 32 is disposed on the atomizing base 30, the liquid inlet 31 is disposed at the bottom of the sliding groove 32, and the stopper 50 is slidably disposed in the sliding groove 32 to block or open the liquid inlet 31. It can be understood that two ends of the atomizing base 30 can be provided with two liquid inlets 31 communicated with the liquid storage cavity 21, two stoppers 50 are provided and movably penetrate through the atomizing base 30 respectively, and the stoppers 50 and the liquid inlets 31 are arranged in a one-to-one correspondence manner.

In one embodiment, the occluding device 50 comprises a pull rod 51 and an occluding portion 52. The pull rod 51 penetrates through the atomizing base 30, a first end of the pull rod 51 is connected with the blocking portion 52, and a second end of the pull rod extends out of the atomizing base 30. The blocking portion 52 is located in the slide groove 32, and the pull rod 51 moves closer to or away from the liquid inlet 31, so that the blocking portion 52 slides in the slide groove 32 to block or open the liquid inlet 31. Can be directly through push-and-pull rod 51 to drive shutoff portion 52 shutoff or open inlet 31, it is more convenient to operate, and the structure sets up more rationally.

The side of the blocking portion 52 away from the atomizing base 30 is further convexly provided with a limiting portion 521, and when the pull rod 51 moves away from the liquid inlet 31, the limiting portion 521 can abut against and limit the atomizing base 30. Through the limiting effect of the limiting part 521, the pull rod 51 can be effectively prevented from driving the blocking part 52 to be pulled out of the atomizing base 30.

It should be noted that the atomizing assembly 10 is a semi-finished product. Before use, the stopper 50 blocks the liquid inlet 31 of the atomizing base 30, so as to prevent the liquid in the liquid storage cavity 21 from leaking from the liquid inlet 31 to the atomizing element 40. When the liquid storage device is used, the stopper 50 needs to be slid away from the atomizing base 30, and the liquid inlet 31 is opened, so that the liquid in the liquid storage cavity 21 can enter the atomizing element 40 through the liquid inlet 31. The extra portion of the pull rod 51 needs to be removed, and the power supply unit 60 is connected, so that the power supply unit 60 is electrically connected to the atomizing element 40. In order to facilitate removal of the excess portion of the tie rod 51, the tie rod 51 is further provided with a snap-off portion 511, and the cross-sectional area of the snap-off portion 511 is smaller than that of the other portions of the tie rod 51. When the atomizing unit 10 and the power supply unit 60 need to be used in combination, the pull rod 51 is pulled off at the position of the pull-off portion 511, and the remaining pull rod 51 is positioned in the atomizing base 30. The arrangement of the breaking part 511 can facilitate breaking the redundant part of the pull rod 51 when the pull rod 51 is pulled out of the atomizing base 30, and avoid that the use is influenced by the overlong part of the pull rod 51 extending out of the atomizing base 30. In addition, in order to facilitate the pushing and pulling of the pull rod 51, a pull tab 53 is fixedly sleeved on the second end of the pull rod 51.

Considering that there is a gap in the sliding fit of the pull rod 51 and the atomizing base 30, oil leakage is likely to occur. Therefore, the atomizing base 30 is provided with a slide passage 33 communicating with the slide groove 32, and an elastic seal 70 is engaged with the slide passage 33. The pull rod 51 passes through the elastic sealing member 70 and moves within the slide 33 toward or away from the liquid inlet 31. The elastic seal 70 may be a silicone seal, a rubber seal, a plastic seal, or the like. In one embodiment, the blocking portion 52 has a plate shape, and the cross-sectional area of the blocking portion 52 is larger than that of the pull rod 51. The slide 33 has a wider section adjacent the liquid inlet 31 to accommodate the sliding fit of the blocking portion 52 with the atomizing base 30. The portion of the slide 33 remote from the liquid inlet 31 is narrower in width to accommodate the sliding fit of the pull rod 51 with the atomizing base 30. The elastic sealing element 70 is clamped in the wider section of the slideway 33 and abuts against the end of the narrower section of the slideway 33.

Referring to fig. 5 and 6, in an embodiment, the atomizing element 40 includes: a liquid absorbing member 41 and a heat generating member 42. The liquid absorbing member 41 is used for absorbing and buffering the liquid entering from the liquid inlet 31, and the liquid absorbing member 41 comprises a body 411 and a flange 412, wherein the body 411 is provided with an atomizing surface, and the flange 412 is arranged on the atomizing surface. The heating element 42 is disposed on the body 411 of the liquid absorbing member 41, and at least one end of the heating element 42 is protruded from the flange 412. The atomizing element 40 has a flange 412 on the liquid absorbing member 41, and after the heat generating member 42 is provided on the liquid absorbing member 41, the end of the heat generating member 42 can be passed through the flange 412. In practical application, it is found that the original structure of the heat generating member 42 and the liquid absorbing member 41 is often not ideal in atomization effect. It is known from careful analysis that, because the heating member 42 is directly disposed on the outer surface of the liquid absorbing member 41, when the heating member 42 is pulled by external force, it is easy to separate from the outer surface of the liquid absorbing member 41, and further the separated heating member 42 is dried, resulting in poor atomization effect. Based on the above situation, flange 412 can play fine fixed action to the tip of generating heat piece 42, and because the tip of generating heat piece 42 is not direct to be drawn forth from the surface of imbibition piece 41, consequently generate heat the setting that piece 42 can be more firm on imbibition piece 41, avoid generating heat piece 42 and directly pull out from the surface of imbibition piece 41, generate heat piece 42 can be more abundant with the liquid heating atomizing in the imbibition piece 41 for atomization effect is better. Moreover, the end of the heating element 42 will not be separated from the liquid absorbing element 41, which causes the heating element 42 in the separated part to be burnt dry, and affects the atomization effect.

In one embodiment, the body 411 is provided with two flanges 412, and two ends of the heat generating member 42 respectively protrude from the corresponding flanges 412. The two ends of the heat generating member 42 can be stably connected with the liquid absorbing member 41 without separation. As shown in fig. 5 and 7, the main body 411 has a cylindrical shape, the outer peripheral surface of the main body 411 is an atomizing surface, and the flange 412 is provided on the outer peripheral surface of the main body 411. The heating element 42 includes a heating wire 421 wound around, the heating wire 421 is combined with the body 411, the heating wire 421 is arranged along the axial direction of the body 411, and two end portions of the heating wire 421 respectively penetrate out of the corresponding flanges 412. It is understood that the body 411 may have other shapes, the surface of the body 411 is a plane, the plane is an atomizing surface, the flange 412 is disposed on the surface of the body 411, the heating wire 421 is disc-shaped, and after the heating wire 421 is disposed on the body 411, two end portions of the heating wire 421 respectively protrude from the corresponding flange 412. The heating element 42 further includes wires 422 disposed at both ends of the heating wire 421, and the wires 422 are extended out of the flange 412.

On the basis of the above embodiment, the lead 422 can penetrate out in a direction perpendicular to the axial direction of the body 411, so that the lead 422 is prevented from penetrating out obliquely, the penetrating consistency of the lead 422 is better, and the processing difficulty of the lead 422 is reduced. Furthermore, a first lead-out portion 413 and a second lead-out portion 414 are respectively formed at opposite ends of the two flanges 412, and the lead 422 is led out from the joint of the first lead-out portion 413, the second lead-out portion 414 and the corresponding flange 412. By providing the first lead-out portion 413 and the second lead-out portion 414, the fixing range of the lead 422 can be made larger, and the fixing effect can be made better. The first lead-out portion 413 and the second lead-out portion 414 may be connected to the atomization surface of the main body 411, or may be provided at a distance from the atomization surface of the main body 411. The lead 422 can pass out from the joint of the first lead-out part 413 and the flange 412, namely, one part of the lead 422 is positioned in the flange 412, and the other part is positioned in the first lead-out part 413; it is also possible that the radially outer peripheral surface of the wire 422 is inscribed in the end face of the flange 412 facing the other flange, i.e. the wire 422 is located completely inside the flange 412; the radially outer peripheral surface of the lead wire 422 may be inscribed in the end surface of the first lead-out portion 413 away from the second lead-out portion 414, that is, the lead wire 422 is completely located within the first lead-out portion 413, or the radially outer peripheral surface of the lead wire 422 may be inscribed in the end surface of the second lead-out portion 414 away from the first lead-out portion 413, that is, the lead wire 422 is completely located within the second lead-out portion 414. The first lead-out portion 413 and the second lead-out portion 414 are protrusions formed by extending opposite to each other on the opposite end surfaces of the two flanges 412, and the cross-sectional shapes of the first lead-out portion 413 and the second lead-out portion 414 may be square, semicircular, trapezoidal, or the like.

It can be understood that the flange 412 increases the fixing range of the wire 422 along the direction perpendicular to the axial direction of the body 411, and in order to avoid the heating wire 421 being arranged in the flange 412 and causing difficulty in discharging atomized smoke, the heating wire 421 may be arranged between the two flanges 412, and the wire 422 passes out of the flange 412. Since the heating wire 421 cannot be located in the flange 412, the wire 422 may pass through the edge of the flange 412 or obliquely pass through the flange 412. This may cause the heater 421 to be not firmly fixed in the axial direction of the body 411, or the wire 422 may be obliquely extended from the flange 412, so that the consistency is difficult to ensure. After the first leading-out part 413 and the second leading-out part 414 are arranged, the fixing range of the lead 422 along the axial direction of the body 411 can be increased, and the lead 422 can directly penetrate out in the axial direction of the body 411 under the condition that the lead 422 can be firmly fixed.

At least a portion of the heating wire 421 is coupled to the atomizing surface of the body 411, and in an embodiment where the heating wire 421 is disposed on the body 411, the heating wire 421 is embedded in the body 411, and the heating wire 421 is inscribed in the atomizing surface of the body 411. Therefore, the heating wire 421 is prevented from being easily deformed when the heating wire 421 is disposed on the liquid absorbing member 41, and the fixing effect of the heating wire 421 is improved. Of course, a part of the heating wire 421 may be buried in the atomizing surface of the body 411, and another part of the heating wire is exposed out of the atomizing surface of the body 411. In addition, the heating wire 421 is located between the first lead-out portion 413 and the second lead-out portion 414, so that the liquid in the liquid absorbing member 41 can directly overflow the atomizing element 40 after being heated and atomized by the heating wire 421, an overflow path is shortened, and rapid smoke formation is ensured. A depression 4112 is provided on the atomizing surface of the body 411, the depression 4112 extends in the axial direction of the body 411, and at least a part of the heating wire 421 is exposed in the depression 4112. The radial edge of the heating wire 421 is inscribed in the body 411, and a portion of the heating wire 421 is exposed from the recess 4112. The heating wire 421 located inside the body 411 is completely wrapped by the body 411, so that the degree of freedom of the heating wire 421 can be more limited, the fixing and supporting effect of the body 411 on the heating wire 421 is better, and the heating wire 421 is effectively prevented from falling off from the body 411. The heating wire 421 inside the body 411 is soaked with relatively more liquid than the heating wire 421 outside the recess 4112. When whole heater 421 generates heat, in a certain period of time, the atomizing temperature that is located the inside heater 421 of body 411 is less than the atomizing temperature that is located the outer heater 421 of sunken 4112, the atomizing smog that is located the inside heater 421 of body 411 spills over to airflow channel 22 from the body 411 surface, the atomizing smog that is located the outer heater 421 of sunken 4112 spills over to airflow channel 22 on sunken 4112, there will be the difference in the taste of two kinds of smog, liquid can atomize under the temperature of difference promptly, the smog taste that finally realizes atomizing component 40 atomizing gained is diversified. In addition, when the heater 421 generates heat, the heater 421 that is located outside the depression 4112 heats up faster than the heater 421 that is located inside the body 411, and the heater 421 that is located outside the depression 4112 reaches the initial atomizing temperature that is converted into gaseous smoke by liquid first, so that the heater 421 that is located outside the depression 4112 can atomize the liquid in a short time, and the atomizing element 40 is ensured to form smoke quickly. The number of the depressions 4112 may be plural and arranged at intervals in the circumferential direction of the body 411.

It should be noted that, in a specific application, the wires 422 are welded to two ends of the heating wire 421, and the resistance value of the wires 422 is small, and the resistance value of the heating wire 421 is large, so as to facilitate the heating and atomizing of the liquid by the heating wire 421, and the heating wire 421 is electrically connected to the power supply assembly 60 through the wires 422. After the lead 422 is welded to the heating wire 421, the heating wire is fixed by a positioning mold, and then the liquid absorbing member 41 is formed by injection molding. Set up through the mould and cave 4112, the corresponding part card of mould is put between two circles of heater 421, can guarantee like this that the interval between every circle of heater 421 sets up more stably, the circle interval that keeps heater 421 that can be better to at atomizing in-process, the heat that heater 421 provided can conduct in imbibition piece 41 more evenly, with promotion holistic atomization performance. The two wires 422 are electrically connected to the two electrodes of the power module 60, respectively. Specifically, two wires 422 extend from the bottom of the atomizing base 30, and portions of the wires 422 extending beyond the bottom of the atomizing base 30 are removed to electrically connect the two poles of the power module 60.

The liquid absorbing member 41 further includes a first connecting portion 415 and a second connecting portion 416 extending axially from both ends of the body 411, and a receiving cavity 417 axially penetrating through the body 411, the first connecting portion 415 and the second connecting portion 416 is provided in the liquid absorbing member 41. The accommodating cavity 417 can be communicated with the liquid inlet 31 of the atomizing base 30, the liquid inlet 31 is arranged on the outer side of the atomizing base 30, liquid in the liquid storage cavity 21 can rapidly enter the liquid absorbing part 41 from the liquid inlet 31, and the accommodating cavity 417 can improve the liquid guiding speed. The stopper 50 is located outside the liquid inlet 31, so that the stopper 50 can block the liquid inlet 31 outside the liquid inlet 31, when the stopper 50 opens the liquid inlet 31, the stopper does not occupy the inner space of the liquid inlet 31, the liquid enters the atomizing element 40 from the liquid inlet 31 at a higher speed, and the liquid storage amount of the atomizing element 40 is larger.

Referring to fig. 6, in one embodiment, the atomizing element 40 further includes a supporting member 43. The supporting member 43 is embedded in the body 411, and the supporting member 43 is closer to the center of the liquid absorbing member 41 relative to the heat generating member 42 to provide resistance against the contraction deformation of the liquid absorbing member 41.

In the first embodiment, the supporting member 43 is in a sleeve shape, and the supporting member 43 is embedded in the body 411 in the axial direction of the body 411.

In the second embodiment, the supporting member 43 has a ring shape, and the supporting member 43 is embedded in the body 411 along the circumferential direction of the body 411. The annular support member 43 may be provided in plurality, and the plurality of support members 43 are provided at intervals in the axial direction of the body 411.

In the third embodiment, as shown in fig. 8, the support 43 has a spiral shape, and the support 43 is embedded in the body 411 in the axial direction of the body 411.

Present imbibition piece 41 is after the shaping, the not good condition of atomization effect can often appear, through meticulous research and continuous experimental operation discovery, in sintering process, because imbibition piece 41 and the difference of the shrinkage deformation degree that produces of the coefficient of expansion of piece 42 that generates heat, can lead to generating heat piece 42 and the separation of imbibition piece 41, the fixed effect of piece 42 that generates heat has been influenced, and generate heat piece 42 and the separation of imbibition piece 41 back, can not effectual heating atomize the liquid in the imbibition piece 41, dry combustion can take place, and then the atomization effect to the liquid in the imbibition piece 41 has been influenced.
