[0042] An embodiment of the present application provides an atomization assembly 100, as shown in the drawings. Figures 1-4 The atomization assembly 100 includes a first tubular body 10, a second liquid guide 20, and a second tubular body 30. The first tubular body 10 defines a first receiving chamber 11. The first receiving chamber 11 is provided with a first liquid guide 12 and a heating element 13. The second tubular body 30 defines a third receiving chamber 31. The first tubular body 10 and the second liquid guide 20 are arranged in the third receiving chamber 31.

[0043] The second liquid guide 20 is used to absorb the liquid matrix that can be atomized. The second liquid guide 20 is made of a flexible fiber material. The suitable fiber material can be any one of non-woven fabric, cotton fiber, or glass fiber rope, so that the second liquid guide 20 can absorb and conduct the liquid matrix through the internal microporous structure or gap.

[0044] The first liquid guide 12 can be made of a porous material, which can be any one of cotton fiber, non-woven fabric, glass fiber rope, porous glass, or porous ceramic. Therefore, the first liquid guide 12 can also absorb and conduct the liquid matrix through the internal microporous structure or gap. Correspondingly, the heating element 13 can be combined on or wound around the first liquid guide 12 by printing, deposition, sintering, or physical assembly. Specifically, the first liquid guide 12 has a through hole 121 longitudinally penetrating the body of the first liquid guide 12, so that the heating element 13 can extend into the through hole 121 to be combined on the hole wall of the through hole 121. The heating element 13 further includes an electrode lead 131 extending out of the through hole 121 to receive the current provided by an external power supply assembly and guide the current to the heating element 13.

[0045] The first tubular body 10 has a first open end 110 and a second open end 120 oppositely arranged along the length direction thereof, and a second side wall 130 extending between the first open end 110 and the second open end 120, the second side wall 130 is provided with at least one first opening 131, so that a partial area of the first wick 12 can be exposed through the first opening 131, and the exposed area and the second wick 20 are in contact with each other, so that the second wick 12 can further transmit the liquid substrate absorbed thereby to the first wick 12, and the first wick 12 in turn transmits the liquid substrate to the heating element 13, and the heating element 13 can heat and atomize the transmitted liquid substrate to generate aerosol, and release the generated aerosol in the first tubular body 10.

[0046] Meanwhile, the side wall of the second tubular body 30 is provided with at least one second opening 32, and the external liquid substrate can enter the second tubular body 30 through the second opening 32 and be absorbed by the second wick 20 in the second tubular body 30, and the second wick 20 in turn can transmit the absorbed liquid substrate to the first wick 12.

[0047] Since the second wick 20 is made of flexible fiber material, the second wick 20 can be easily bent, for example, Figure 5 As shown, the second wick 20 includes a first portion 21 and a plurality of second portions 22 capable of being bent from the first portion 21 and arranged at intervals, the number of the second portions 22 can be set according to the specific application scenario, in the embodiment, the number of the second portions 22 is 4, so before the second portions 22 are bent, the first wick 20 is in a planar "cross" shape as shown in Figure 5 and Figure 3 After the second portions 22 are bent.

[0048] As shown in Figure 2 and Figure 3 The atomization assembly 100 further includes a bracket 40 arranged in the third accommodation chamber 31, the bracket 40 has a first end portion 41 and a second end portion 42 oppositely arranged along the length direction thereof, and a first side wall 43 extending between the first end portion 41 and the second end portion 42, the bracket 40 further defines a second accommodation chamber 44 extending between the first end portion 41 and the second end portion 42, and the first tubular body 10 is arranged in the second accommodation chamber 44, so that the first wick 12 and the heating element 13 are both located in the second accommodation chamber 44. Among them, the second end portion 42 is open to provide an entrance for the first tubular body 10 to enter the second accommodation chamber 44, and the first end portion 41 is provided with an air outlet hole 411 for the aerosol to flow through, and the aerosol generated by heating the liquid substrate by the heating element 13 can escape from the air outlet hole 411 of the first end portion 41 to the atomization assembly 100.

[0049] The first sidewall 43 has a plurality of first notches 431 extending along the length of the second tubular body 30. The number of first notches 431 is the same as the number of second portions 22 of the second liquid guiding member 20, and the bent second portions 22 are correspondingly accommodated in the first notches 431. It is easy to understand that the first notches 431 and the openings 131 of the second sidewall 130 are correspondingly connected, so that the second portions 22 of the second liquid guiding member 20 can contact the first liquid guiding member 12 through the first notches 431 to transfer the liquid matrix absorbed on the second liquid guiding member 20 to the first liquid guiding member 12.

[0050] Accordingly, when assembling the atomizing assembly 100, the first liquid guide 12 can be first assembled into the first receiving chamber 11 in the first tubular body 10, then the first tubular body 10 can be installed into the second receiving chamber 44 of the bracket 40, then the second part 22 of the second liquid guide 20 can be bent from the first part 21 and placed into the first notch 431, and finally the bracket 40 can be installed into the third receiving chamber 31 of the second tubular body 30, thereby forming the atomizing assembly 100 described above.

[0051] In this embodiment, by setting up a support 40, before the second liquid guide 20 is installed into the second tubular body 30, the second part 22 of the second liquid guide 20 is bent and placed in the first notch 431 on the support 40. This effectively alleviates the squeezing of the second liquid guide 20 during the installation process when the second liquid guide 20 is installed into the second tubular body 30, thereby alleviating the wrinkles caused by the squeezing force on the second liquid guide 20.

[0052] In some embodiments, such as Figure 5 and Figure 6 As shown, the first part 21 is disposed at the first end 41 of the support 40, and the second part 22 extends from the first part 21 toward the second end 42 of the support 40. When the support 40 is assembled into the third receiving chamber 31 of the second tubular body 30, the first end 41 enters the third receiving chamber 31 first, prior to the second end 42. That is, the second tubular body 30 first receives the support 40 from the first end 41 of the support 40, so that the receiving direction is the same as the extension direction of the second part 22, so as to further alleviate the squeezing force on the second liquid guide 20 when it is installed in the second tubular body 30.

[0053] In some embodiments, in order to improve the transmission efficiency of the liquid matrix, the second liquid guiding element 20 is made of non-woven fabric. Since non-woven fabric is relatively soft and easily deformed, it is necessary to avoid the non-woven fabric being subjected to large compressive forces during assembly. Therefore, the atomizing component 100 provided in this application is more advantageous when assembling the second liquid guiding element 20 made of non-woven fabric into the second tubular body 30.

[0054] In some embodiments, as shown in Figure 2 The cross-sectional shape of the first notch 431 is adapted to the cross-sectional shape of the second portion 22, so that when the second portion 22 is placed in the first notch 431, the second portion 22 can just fill the first notch 431 completely, that is, the second portion 22 just seals the first notch 431, as shown in Figure 6 , avoiding the existence of a gap between the second portion 22 and the inner wall of the first notch 431.

[0055] Further in some embodiments, as shown in Figure 2 The first notch 431 extends from the first end 41 to the second end 42, so that the area of the second portion 22 placed in the first notch 431 is also larger, thereby increasing the contact area of the second liquid guide 20 and the first liquid guide 12, and accordingly improving the transmission efficiency of the liquid matrix.

[0056] In some embodiments, as shown in Figure 7 The first end 41 and the inner wall of the second tubular body 30 define a receiving space 412, and the airflow flowing through the air outlet hole 411 further enters the receiving space 412. The receiving space 412 is provided with a sealing element 50, which can be any one of silicone, rubber, or latex, etc. The sealing element 50 is installed in the receiving space 412 by interference, the sealing element 50 is provided with a through hole for guiding the flow of aerosol, and in use, the sealing element 50 is docked with the air guide pipe 220 (see Figure 9 ), so that the sealing element 50 seals the flow path of the aerosol, avoiding leakage of the aerosol.

[0057] In some embodiments, as shown in Figure 3 and Figure 6 The end face of the first end 41 is further provided with a protrusion 413 extending away from the second end 42, and the first portion 21 of the second liquid guide 20 is provided with a through hole 211, and the protrusion 412 penetrates the through hole 211, so that the first portion 21 of the second liquid guide is sleeved on the protrusion 413 to position the second liquid guide 20 during assembly. In a specific assembly, the first portion 21 of the second liquid guide 20 can be positioned by sleeving on the protrusion 414, and then the second portion 22 is bent from the first portion 21 and placed in the first notch 431.

[0058] In some embodiments, as shown in Figure 3 The protrusion 414 is hollow and communicates with the first tubular body 10, and the aerosol generated in the first tubular body 10 can escape from the atomization assembly 100 through the protrusion 414.

[0059] In some embodiments, as shown in Figure 2As shown, the second side wall 130 of the first tubular body 10 is also provided with a second notch 132 extending from the first opening end 110 to the second opening end 120. The second notch 132 can slow down the stress of the first tubular body 10, and facilitate the assembly of the first liquid guide 12 into the first receiving chamber 11, so as to avoid the first liquid guide 12 from being deformed due to a large extrusion force during the assembly.

[0060] It should be noted that the partial region of the first liquid guide 12 is also exposed through the second notch 132, so as to be in contact with the second liquid guide 20 to receive the liquid matrix.

[0061] In some embodiments, as shown in Figure 2 The bracket 40 is also provided with a shielding part 45 for shielding at least a part of the second notch 132, so as to prevent the aerosol generated by atomization from flowing through the second notch 132 to cause leakage.

[0062] For example, in Figure 8 , since the partial region of the first liquid guide 12 is exposed through the second notch 132, the shielding part 45 does not need to shield the entire second notch 132 in Figure 8 , but only needs to shield the excess part of the second notch 132, and the part of the first liquid guide 12 exposed does not need to be shielded.

[0063] In some embodiments, if the second notch 132 extends too short and has not reached the position of the first liquid guide 12, that is, the first liquid guide 12 cannot be exposed through the second notch 132, the shielding part 45 needs to shield the entire second notch 132 at this time.

[0064] An embodiment of the present application also provides a kind of atomizer 200, as shown in Figure 9 The atomizer 200 is provided with a liquid storage cavity 210 for storing atomizable liquid matrix, and a gas guide pipe 220 longitudinally extending in the liquid storage cavity 210, the gas guide pipe 220 is communicated with the suction port 230, and the gas guide pipe 220 is used to transmit the aerosol after atomization, so that the aerosol is transmitted to the suction port 230 for user to smoke, and the user can smoke the aerosol by suction on the suction port 230.

[0065] The liquid storage cavity 210 is provided with a liquid storage member 240 and a third liquid guide 260 in contact with the liquid storage member 240, and the third liquid guide 260 is used to suck the liquid matrix in the liquid storage cavity 210 and deliver the sucked liquid matrix to the liquid storage member 240, the third liquid guide 260 and the liquid storage member 240 are also made of the porous material in the above-mentioned embodiments, so that the liquid storage member third liquid guide 260 and 240 can suck the liquid matrix and deliver the liquid matrix through the internal gap or microporous structure.

[0066] Further, the liquid storage member 240 is in contact with the second liquid guide 20 of the atomization assembly 100 through the second opening 32 of the second tubular body 30 of the atomization assembly 100, and then the liquid substrate in the liquid storage member 240 is transmitted to the second liquid guide 20, and then transmitted to the first liquid guide 12 by the second liquid guide 20. It should be noted that in some embodiments, the third liquid guide 260 can also not be arranged in the liquid storage cavity 210, and the liquid storage cavity 210 only needs to be filled with the liquid storage member 240 to hold the liquid substrate in the liquid storage cavity 210.

[0067] The liquid storage member 240 is provided with a through hole (not shown in the figure) longitudinally penetrating the body, and the atomization assembly 100 described in the above embodiments is arranged in the through hole. One end of the air guide pipe 220 is in communication with the mouthpiece 230, and the other end is in communication with the air outlet hole 411 of the atomization assembly 100, and then the aerosol generated by the atomization assembly 100 can escape from the air outlet hole 411 and enter the air guide pipe 220, and then be transmitted to the mouthpiece 230 by the air guide pipe 220.

[0068] As shown in Figure 9 , the atomizer 200 further comprises a base 250 arranged opposite to the mouthpiece 230, and the base 250 is provided with an air inlet 251 and an electrode hole. The air inlet 251 is used to provide an air flow inlet for external air to enter the atomizer 200, and the external air further flows into the first tubular body 10 in the atomization assembly 100, and then carries the aerosol released in the first tubular body 10 and flows into the air guide pipe 220, and finally is transmitted to the mouthpiece 230 by the air guide pipe 220 for the user to smoke, as shown in the air flow path R in Figure 9 . The electrode hole is provided with a conductive electrode 252, and the conductive electrode 252 is electrically connected with the heating element 13 of the atomization assembly 100 through the electrode lead 131. A part of the conductive electrode 252 is exposed to the end face of the base 250, so as to be electrically connected with the power supply assembly through the exposed part, and then the power supply assembly provides power for the atomizer 200.

[0069] An embodiment of the present application further provides an electronic atomization device, as shown in Figure 10 , comprising the atomizer 200 described in the above embodiments, and a power supply assembly 300 for supplying power for the atomizer 200.

[0070] In an optional implementation, such as Figure 10As shown, the power supply assembly 300 includes a receiving cavity 370 disposed at one end along the length direction for receiving and accommodating at least a portion of the atomizer 200, and an electrical contact 330 exposed at least partially on the surface of the receiving cavity 370, for forming an electrical connection with the conductive electrode 252 of the atomizer 200 to supply power to the atomizer 200 when at least a portion of the atomizer 200 is received and accommodated in the power supply assembly 300.

[0071] A sealing element 360 is provided within the power supply assembly 300, and this sealing element 360 divides at least a portion of the internal space of the power supply assembly 300 to form the aforementioned receiving cavity 370. Figure 10 In the preferred embodiment shown, the seal 360 is configured to extend along the cross-sectional direction of the power assembly 300, and is preferably made of a flexible material such as silicone, thereby preventing the liquid matrix that seeps from the atomizer 200 into the receiving cavity 370 from flowing into components such as the controller 320 and sensor 350 inside the power assembly 300.

[0072] exist Figure 10 In the preferred embodiment shown, the power supply assembly 300 further includes a battery cell 310 for power supply located at the other end of the receiving cavity 370 along its length; and a controller 320 disposed between the battery cell 310 and the receiving cavity 370, the controller 320 being operable to guide current between the battery cell 310 and the electrical contact 330.
