[0038] An embodiment of the present application provides a nebulizer 100 for atomizing a liquid matrix to generate an aerosol, such as Figure 1 As shown, the atomizer 100 includes a main shell 10 and a bottom cover 20, which are fixedly connected to form the shell of the atomizer 100. The main shell 10 is provided with an air outlet 11 for aerosol to escape from the atomizer 100, and the bottom cover 20 is provided with an air inlet 21 for external air to enter the atomizer 100. When the user inhales, the external air enters the atomizer 100 through the air inlet 21, and carries the aerosol generated by atomization to the air outlet 11 through the air flow path inside the atomizer 100, and the user can inhale the aerosol by inhaling at the air outlet 11.

[0039] like Figure 2 As shown, a first supporting member 30 and a second supporting member 20 are provided in the main housing 10, the first supporting member 30 is supported on the second supporting member 20, the first supporting member 30 and the inner wall of the main housing 10 define a liquid storage chamber 40 for storing an atomizable liquid matrix, and in order to prevent the liquid matrix in the liquid storage chamber 40 from leaking from the assembly gap between the first supporting member 30 and the inner wall of the main housing 10, a sealing member 50 is supported on the first supporting member 30, and the sealing member 50 elastically abuts against the inner wall of the main housing 10, thereby sealing the liquid storage chamber 40, so that the liquid matrix in the liquid storage chamber 40 flows along a preset route.

[0040] like Figure 2 and Figure 3 As shown, a receiving chamber 31 is provided in the first supporting member 30, a first air guide tube 32 extends in the receiving chamber 31, an atomization assembly 33 is provided in the first air guide tube 32, the atomization assembly 33 includes a liquid guide member 331 and a heating element 332, the liquid guide member 331 is formed with a longitudinal through hole 3311, so that the liquid guide member 331 has an outer surface 3312 and an inner surface 3313, the heating element 332 is combined on the inner surface 3313, the liquid guide member 331 is used to absorb the liquid matrix in the liquid storage chamber 40, and transfer the liquid matrix to the heating element 332 on the inner surface 3313, the heating element 332 heats the liquid matrix and atomizes it to generate an aerosol.

[0041] The liquid guide 331 can be made of flexible fibers, such as cotton fibers, non-woven fabrics, glass fiber ropes, etc., or made of porous materials with microporous structures, such as porous ceramics, so that the liquid guide 331 can transfer the absorbed liquid matrix to the inner surface 3313, and then transfer it to the heating element 332 for heating and atomization. The heating element 332 can be combined with the liquid guide 331 by printing, deposition, sintering or physical assembly, or wrapped on the liquid guide 331.

[0042] It is easy to understand that the sealing member 50 is provided with a first liquid guide hole (not shown), and the tube wall of the first air guide tube 32 is provided with a second liquid guide hole (not shown), so that the liquid matrix in the liquid storage cavity 40 can flow into the receiving chamber 31 through the first liquid guide hole, and then flow into the liquid guide member 331 through the second liquid guide hole and then be absorbed by the liquid guide member 331. Figure 2 The flow route R of the liquid matrix is ​​shown in FIG.

[0043] The aerosol generated by the atomization of the atomization assembly 33 is released into the through hole 3311, and the first air duct 32 can transmit the aerosol. At the same time, the main shell 10 is also formed with a second air duct 12 extending in the liquid storage chamber 40. One end of the second air duct 12 extends into the first air duct 32 so as to be connected with the second air duct 32, and the other end of the second air duct 12 is connected to the air outlet 11. Therefore, when the user inhales at the air outlet 11, the external air enters the atomizer 100 through the air inlet 21, and flows into the through hole 3311 through the internal air flow channel of the atomizer 100, and then carries the aerosol in the through hole 3311 through the first air duct 32 to the second air duct 12, and finally is transmitted to the air outlet 11 by the second air duct 12, and the user can inhale the aerosol at the air outlet 11.

[0044] like Figure 2 , Figure 6 and Figure 7 As shown, the atomizer 100 also includes an electrode hole 60, in which an electrode column 70 is installed, and the bottom of the electrode column 70 is exposed to the housing of the atomizer 100 so as to be electrically connected to an external power supply mechanism. A clamping structure is defined between the first support member 30 and the second support member 20. The atomizer assembly 33 also includes an electrode lead 333 electrically connected to the heating element 332, and the electrode lead 333 includes a first section 3331 and a second section 3332. The first section 3331 extends into the electrode hole 60, and the first section 3331 is clamped between the inner wall of the electrode hole 60 and the electrode column 70, so that the first section 3331 is electrically connected to the electrode column 70, and then the electrode column 70 can conduct the electric energy of the external power supply mechanism to the heating element 332 through the electrode lead 333.

[0045] The second section 3332 is clamped in the above-mentioned clamping structure, so that the first section 3331 is maintained in the electrode hole 60, and then when the electrode column 70 is assembled into the electrode hole 60, the first section 3331 will not be driven by the electrode column 70 to shift, that is, in the process of the electrode column 70 being assembled into the electrode hole 60, the electrode lead 333 will not be pulled by the electrode column 70, and then the electrode lead 333 will not pull the atomization assembly 33.

[0046] In some embodiments, Figure 4 and Figure 5As shown, the clamping mechanism includes a gap 34 located between the first support member 30 and the second support member 20, the first section 3331 is clamped between the electrode column 70 and the inner wall of the electrode hole 60, and the second section 3332 is clamped in the gap 34, thereby keeping a partial section of the electrode lead in the electrode hole 60.

[0047] Further in some embodiments, Figure 6 and Figure 7 As shown, the gap 34 includes a first gap 341 and a second gap 342 extending transversely, and a third gap 343 extending longitudinally, the third gap 343 connects the first gap 341 and the second gap 342, the second section 3332 includes a first part clamped in the first gap 341, and a second part clamped in the second gap 342, and the second section 3332 is fixed by clamping the first gap 341 and the second gap 342. The first gap 341 can be used as an entrance for the electrode lead 333 to enter the gap 34, and the second gap 342 connects to the electrode hole 60 as an exit for the electrode lead 333 to extend from the gap 34 to the electrode hole 60.

[0048] In some embodiments, Figure 6 and Figure 7 As shown, the second support member 20 includes a first extension portion 22 extending toward the first support member 30, and the first support member 30 includes a second extension portion 35 extending toward the second support member 20. The first extension portion 22 and the second extension portion 35 serve as clamping structures for clamping a portion of the electrode lead 333, thereby fixing the electrode lead 333.

[0049] Further in some embodiments, Figure 6 As shown, the first extension portion 22 and the second extension portion 35 are staggered to form a gap 34 for the electrode lead 333 to pass through. When the electrode lead 333 passes through the gap 34, a portion of the electrode lead 333 is clamped between the first extension portion 22 and the second extension portion 35.

[0050] Further in some embodiments, Figure 6 As shown, the first extension portion 22 and the first support member 30 define an inlet 341 of the gap 34, and the second extension portion 35 and the second support member 20 define an outlet 342 of the gap 34. The inlet 341 is used for the electrode lead 333 to enter the gap 34, and the outlet 343 is connected to the electrode hole 60, and is used for the electrode lead 333 to extend into the electrode hole 60. This arrangement makes the second section 3332 more firmly fixed in the gap 34. In some other embodiments, the inlet 341 can also be defined by the second extension portion 35 and the second support member 20, and the outlet 342 is defined by the first extension portion 22 and the first support member 30.

[0051] Furthermore, in some embodiments, the distance between the first extension portion 22 and the second extension portion 35 is greater than the distance between the first extension portion 22 and the first support member 30, and greater than the distance between the second extension portion 35 and the second support member 20, so that the electrode lead 333 can smoothly pass through the gap 34 and extend into the electrode hole 60.

[0052] In some embodiments, Figure 5 and Figure 7 As shown, after the first section 3331 of the electrode lead 333 extends into the electrode hole 60 , it extends toward the first support member 30 , so as to achieve stable electrical contact with the electrode column 70 after the electrode column 70 is inserted into the electrode hole 60 .

[0053] In some embodiments, Figure 7 and Figure 8 As shown, the electrode hole 60 includes a first part 61 and a second part 62, the first part 61 is defined by the first support member 30, and the second part 62 is defined by the second support member 20. The hole wall of the first part 61 is provided with a notch 611 extending to the end face of the first support member 30, and then when the electrode column 70 is inserted into the electrode hole 60, the notch 611 can partially release the squeezing force applied to the electrode hole 60 when the electrode column 70 is inserted, thereby preventing the first support member 30 from cracking under the squeezing force.

[0054] And, in some embodiments, as Figure 8 As shown, the notch 611 includes a side wall 6111 and a bottom wall 6112. The bottom wall 6112 is configured in an arc shape. The arc-shaped bottom wall 6112 can release the squeezing force more evenly and can also provide a force opposite to the squeezing force to be applied to the electrode column 70, thereby preventing the electrode column 70 from loosening in the electrode hole 60.

[0055] It should be noted that the notch 611 can also be provided on the hole wall of the second portion 62, so as to prevent the second support member 20 from cracking when the electrode column 70 is inserted into the electrode hole 60. Alternatively, the notch 611 is provided on both the hole wall of the first portion 61 and the hole wall of the second portion 62.

[0058] according to Fig. 9 In the preferred implementation shown, the electrode column 70 in the above embodiment is provided at the end of the atomizer 100 opposite to the power supply assembly 200 along the length direction, so that when at least a portion of the atomizer 100 is received in the receiving cavity 210, the electrode column 70 contacts and abuts against the electrical contact 220 to form conductivity.

[0059] A sealing member 230 is disposed in the power source assembly 200, and the sealing member 230 separates at least a portion of the internal space of the power source assembly 200 to form the above receiving cavity 210. Fig. 9 In the preferred embodiment shown, the seal 230 is configured to extend along the cross-sectional direction of the power supply assembly 200, and is preferably made of a flexible material such as silicone, thereby preventing the liquid matrix that seeps from the atomizer 100 into the receiving chamber 210 from flowing to the controller 240, sensor 250 and other components inside the power supply assembly 200.

[0060] exist Fig. 9 In the preferred embodiment shown, the power supply assembly 200 also includes a battery cell 260 for powering the battery at the other end away from the receiving cavity 210 along the length direction; and a controller 240 disposed between the battery cell 260 and the accommodating cavity 210, which is operable to guide current between the battery cell 210 and the electrical contact 220.

[0061] During use, the power supply assembly 200 further includes a sensor 250 for sensing the suction airflow generated when suction is performed through the air outlet 11 of the atomizer 100 , and then the controller 220 controls the battery cell 210 to output current to the atomizer 100 according to the detection signal of the sensor 250 .

[0062] Further in Fig. 9 In the preferred embodiment shown, the power supply assembly 200 is provided with a charging interface 270 at the other end away from the receiving cavity 210 for charging the battery cell 210 .
