[0060] This application discloses an atomizing structure, which includes some or all of the structures described in the following embodiments; that is, the atomizing structure includes some or all of the following technical features. In one embodiment of this application, an atomizing structure 100 is as follows: Figure 1 As shown, it includes an atomizing core assembly 110 and a heating element 120; combined with Figure 2 The atomizing core assembly 110 includes an atomizing section 111 and a guiding section 112. The heating element 120 is at least partially embedded inside the atomizing section 111, and the atomizing section 111 is fixed in the guiding section 112. The atomizing section 111 has an outer wall 116, and the guiding section 112 has an inner wall portion 112A. Figure 3 and Figure 4The outer wall 116 is partially in contact with the inner wall portion 112A, the guide portion 112 is in contact with the atomization medium, and sequentially passes the atomization medium to the atomization portion 111 through the inner wall portion 112A and the outer wall 116, the outer wall 116 forms a first atomization surface, and a first air passage 191 for transmitting the aerosol generated by the first atomization surface is formed between the outer wall 116 and the inner wall portion 112A. The above-mentioned atomization structure has the following advantages: on the one hand, the atomization surface and the liquid absorption surface are physically separated, the heating body indirectly contacts the atomization medium in the liquid storage cavity through the guide portion, and thus there is a long distance between the heating body and the atomization medium in the liquid storage cavity, which effectively isolates the heat transfer, avoids deterioration of the atomization medium in the liquid storage cavity caused by high temperature, and makes the whole atomization structure have high heating efficiency; on the other hand, the outer wall of the atomization portion is directly in contact with the inner wall portion of the guide portion, the guide portion obtains the atomization medium through the liquid absorption surface, the oil guiding area is large and the oil is guided in all directions, which can effectively ensure sufficient oil supply and smooth delivery of the atomization medium to the heating body, and the atomization amount is large, thereby solving the problems of poor atomization effect and insufficient smoke amount in the traditional atomization.

[0061] In one embodiment, the guide portion 112 is provided with a liquid absorption surface 119 in contact with the atomization medium, the liquid absorption surface 119 is arranged to absorb the atomization medium into the inside of the guide portion 112, and sequentially pass the atomization medium to the inside of the atomization portion 111 through the inner wall portion 112A and the outer wall 116. Further, in one embodiment, the guide portion 112 has an outer wall portion 112B, and the outer wall portion 112B is provided with the liquid absorption surface 119. In one embodiment, an atomization structure 100 includes an atomization core assembly 110 and a heating body 120; the atomization core assembly 110 includes an atomization portion 111 and a guide portion 112, and the heating body 120 is at least partially embedded in the inside of the atomization portion 111, and the atomization portion 111 is fixed in the guide portion 112; the atomization portion 111 has an outer wall 116, the guide portion 112 has an inner wall portion 112A and an outer wall portion 112B, and the outer wall 116 is partially in contact with the inner wall portion 112A; the guide portion 112 is in contact with the atomization medium at the outer wall portion 112B, and sequentially passes the atomization medium to the inside of the atomization portion 111 through the outer wall portion 112B, the inner wall portion 112A and the outer wall 116; the outer wall 116 forms a first atomization surface, and a first air passage 191 for transmitting the aerosol generated by the first atomization surface is formed between the outer wall 116 and the inner wall portion 112A. In this embodiment, the heating body 120 includes a spiral heating wire, a mesh heating wire and a sheet heating wire; and / or, the heating body 120 is provided with a lead wire extending outside the atomization portion 111. In one embodiment, the heating body 120 is integrally formed with the atomization portion 111 and located between the outer wall 116 and the inner wall 115.

[0062] In one embodiment, the atomizing core assembly 110 includes an atomizing section 111 and a guiding section 112; the atomizing structure 100 for realizing the atomizing function includes the atomizing section 111 and a heating element 120, with the heating element 120 embedded in the atomizing section 111; the guiding section 112 is a cylindrical structure including an inner wall section 112A and an outer wall section 112B, with the inner wall section 112A connected to the atomizing section 111, and the outer wall section 112B at least partially used to contact the atomizing medium, so that the atomizing medium is transferred from the inside of the guiding section 112 to the atomizing section 111, and finally atomized into an aerosol by the heating element 120.

[0063] Furthermore, in one embodiment, at least 80% of the outer surface of the guide portion 112, i.e., the outer wall portion 112B, is provided as the liquid-absorbing surface 119. Furthermore, in one embodiment, as... Figure 4 or Figure 5 As shown, the entire outer surface of the guide portion 112 is formed as the liquid-absorbing surface 119, or the entire surface of the guide portion 112 facing away from the outer wall 116 is formed as the liquid-absorbing surface 119. In one embodiment, the guide portion 112 is a regular cylindrical structure. In another embodiment, the entire outer surface of the guide portion 112 away from the atomizing portion 111 is formed as the liquid-absorbing surface 119. In one embodiment, both the atomizing portion 111 and the guide portion 112 are made of microporous material with a certain porosity, that is, the interior of the atomizing core assembly 110 has a porous structure, and both the atomizing portion 111 and the guide portion 112 have porous structures. In various embodiments, the porous structure can also be referred to as a hollow porous body, exhibiting a "porous" morphology at the microscopic level to facilitate the transport of the atomizing medium within the atomizing core assembly 110 and its atomizing section 111. Due to the characteristics of the porous structure, the atomizing medium is transported through gravity and capillary action, enabling the heating element 120 to heat the atomizing medium in the atomizing section 111 to generate an aerosol, which then permeates through the first air passage 191 and the second air passage 192 outside the atomizing section 111. Further, the pore size of the porous structure is 100 nanometers to 120 micrometers; in one embodiment, the pore size of the porous structure is 1 micrometer to 100 micrometers. In one embodiment, the pore size of the porous structure is 10 micrometers to 50 micrometers. The porous structure is made of ceramic or glass, etc. In one embodiment, the internal porosity of the porous structure is 30% to 90%; in another embodiment, the internal porosity of the porous structure is 50% to 65%. This design allows the atomizing medium to be transmitted only through the interior of the atomizing section 111.

[0064] Further, in one of the embodiments, the porosity of the guiding portion 112 is greater than that of the atomizing portion 111, so that the total amount of the atomizing medium supplied by the guiding portion 112 is sufficient, while the relatively small porosity of the atomizing portion 111 can prevent the atomizing portion 111 from leaking due to excessive porosity, and facilitate the guiding of the atomizing medium into the atomizing portion 111. Further, in one of the embodiments, the interior of the guiding portion 112 is provided with different pores to form a guiding channel, and the liquid absorbing surface 119 transports the atomizing medium to the atomizing portion 111 or the connecting section 114 through the guiding channel, so as to facilitate the accurate and uniform transportation of the atomizing medium to the heating body 120 in the atomizing portion 111, thereby obtaining uniform aerosol. Moreover, such design connects the atomizing portion 111 and the guiding portion 112, and transports the atomizing medium, such as oil, through the entire tubular outer wall of the guiding portion 112, which has a large oil guiding area and can guide oil in all directions, so as to effectively ensure sufficient supply of the atomizing medium to the heating body 120, while the atomizing portion 111, i.e., the atomizing portion 111, includes multiple atomizing regions inside and outside the tube, and has a large atomizing amount.

[0065] In one of the embodiments, as shown in Figure 2 , the atomizing portion 111 has an inner wall 115 forming a second atomizing surface and a second air passage 192 for transporting the aerosol generated by the second atomizing surface. In one of the embodiments, as shown in Figure 2 and Figure 4 , the atomizing core assembly 110 forms an avoidance groove 114 at the bottom of the atomizing portion 111, so that the first air passage 191 and the second air passage 192 are in fluid communication through the avoidance groove 114. Further, in one of the embodiments, as shown in Figure 2 , the atomizing portion 111 has a top 117 configured to retain the fluid communication of the first air passage 191 and the second air passage 192 during installation, such as installation of other components. In one of the embodiments, as shown in Figure 2 and Figure 3As shown, the atomization core assembly 110 forms a flow-through area 113 at the top 117 of the atomization portion 111 to fluidly connect the first air passage 191 and the second air passage 192 through the avoidance slot 114. That is, the upper end surface of the atomization portion 111 is lower than the upper end surface of the guide portion 112, or the lower end surface of the atomization portion 111 is higher than the lower end surface of the guide portion 112, to ensure that the incoming air can pass through both the first air passage 191 and the second air passage 192 and flow out of both the first air passage 191 and the second air passage 192. Such a design is advantageous to avoid blocking the first air passage 191 and the second air passage 192 due to a tight fit installation, thereby ensuring that the aerosol generated by the first atomization surface is transmitted through the first air passage 191 and the aerosol generated by the second atomization surface is transmitted through the second air passage 192.

[0066] Further, in one embodiment, the first air passage 191 and the second air passage 192 are arranged to communicate with two sides of the atomization core assembly 110, respectively. In this embodiment, one side of the atomization core assembly 110 is provided with an air inlet end, and the first air passage 191 and the second air passage 192 respectively communicate with the air inlet end; the other side of the atomization core assembly 110 is provided with an air outlet end, and the first air passage 191 and the second air passage 192 respectively communicate with the air outlet end. Further, in one embodiment, the atomization core assembly 110 forms the flow-through area 113 at the air outlet end and forms the avoidance slot 114 at the air inlet end. The design of the air inlet end and the air outlet end, i.e., the design of the flow-through area 113 and the avoidance slot 114, enables external air to enter the atomization area formed by the inner wall 115 and the outer wall 116 due to the action of the heating body 120, thereby forming an external-internal-external gas flow-through channel, so that the aerosol generated by heating the atomization medium by the heating body 120 can be mixed with external air and then output.

[0067] In one embodiment, as shown in Figure 2 and Figure 3 the atomization core assembly 110 is provided with a limiting step 118 higher than the atomization portion 111 on the guide portion 112. Further, in one embodiment, the atomization core assembly 110 is provided with a limiting step 118 higher than the atomization portion 111 on the guide portion 112, and the limiting step 118 has an outer shape smaller than the outer shape of the guide portion 112 to form a mounting position. Further, in one embodiment, in the direction of gravity, the height of the atomization portion 111 is smaller than the height of the guide portion 112. Further, in one embodiment, as shown in Figure 5 and Figure 8As shown, in the direction of gravity, the guide part 112 and the atomizing part 111 are set at the same height; this design is conducive to making comprehensive use of gravity and capillary action to transport the atomizing medium from inside the atomizing core assembly 110.

[0068] In one embodiment, such as Figure 2 As shown, in the direction of gravity, the height of the atomizing part 111 is greater than the height of the guiding part 112, but less than the height of the limiting step 118. The design of the limiting step is beneficial in two ways: firstly, it facilitates the sealing connection of the vent pipe and prevents the atomizing medium from entering the first air passage 191 and the second air passage 192; secondly, it helps to ensure that the aerosol in the first air passage 191 and the second air passage 192 enters the vent pipe, preventing it from being sealed and thus preventing fluid communication.

[0069] In one embodiment, the number of first air passages 191 is at least two; and / or, each of the first air passages 191 is evenly distributed. In one embodiment, the atomizing part 111 has a central axis, and each of the first air passages 191 is evenly distributed relative to the central axis. Further, in one embodiment, as... Figure 5 As shown, the atomizing core assembly 110 has an axisymmetric structure, the atomizing section 111 has a central axis, and there are two first air channels 191, each of which is evenly arranged relative to the central axis. In one embodiment, the inner wall 115 of the atomizing section 111 forms a second atomizing surface and a second air channel 192 for transmitting the aerosol generated by the second atomizing surface. Figure 6 and Figure 7 The second airway 192 is cylindrical. In this embodiment, for example... Figure 8 As shown, the outer wall portion 112B of the guide portion 112 is all configured as the liquid absorption surface 119.

[0070] In one embodiment, such as Figure 4 or Figure 6 As shown, the outer wall 116 and the inner wall portion 112A have surface contact, and the contact surfaces are tangent. Or as... Figure 9 or Figure 10 As shown, the outer wall 116 and the inner wall portion 112A have surface contact, and the contact surfaces are tangent. Further, in one embodiment, as... Figure 3 and Figure 4 As shown, the outer wall 116 or the inner wall portion 112A has a protruding structure, and the outer wall 116 and the inner wall portion 112A are in contact with each other through the protruding structure.

[0071] In one embodiment, such as Figure 5 and Figure 6As shown, the shortest distance from the inner wall 115 of the atomization part 111 to the outer wall part 112B of the guide part 112 is less than or equal to the sum of the distance from the inner wall 115 to the outer wall 116 and the distance from the inner wall part 112A to the outer wall part 112B; when the thickness of the atomization part 111 is consistent, the distance from the inner wall 115 to the outer wall 116 is the thickness of the atomization part 111, which can be referred to as the first thickness; when the thickness of the guide part 112 is consistent, the distance from the inner wall part 112A to the outer wall part 112B is the thickness of the guide part 112, which can be referred to as the second thickness; the shortest distance from the inner wall 115 to the outer wall part 112B is less than or equal to the sum of the first thickness and the second thickness. For the embodiment in which the outer wall 116 and the inner wall part 112A have a surface contact and the contact surfaces are tangent, as shown in Figure 10 the shortest distance from the inner wall 115 to the outer wall part 112B is equal to the sum of the first thickness and the second thickness. For the embodiment in which the outer wall 116 and the outer wall part 112B have a surface contact and the contact surfaces are tangent, as shown in Figure 6 and Figure 7 the shortest distance from the inner wall 115 to the outer wall part 112B is equal to the first thickness, which is also equal to the second thickness, and in this embodiment, the first thickness is equal to the second thickness. That is, the shortest distance from the inner wall 115 to the outer wall part 112B is less than the sum of the first thickness and the second thickness. The remaining embodiments are similar and will not be described in detail. Such a design is beneficial for increasing the contact area between the outer wall of the atomization part and the inner wall part of the guide part, and for improving the delivery efficiency of the atomization medium from the guide part to the atomization part, which has a large oil guiding area and guides oil in all directions, can effectively ensure sufficient oil supply, large atomization amount, and solve the problem of poor atomization effect and insufficient smoke amount of traditional atomization.

Such a design, one important point of the present embodiment is to make the heating body 120 heat uniformly, thereby ensuring the uniformity of heating of the atomization medium and the consistency of the atomized aerosol, and another important point is to make the heating body 120 indirectly contact the atomization medium in the liquid storage cavity to effectively isolate the heat transfer, which is beneficial for avoiding deterioration of the atomization medium in the liquid storage cavity caused by high temperature.

[0073] To avoid leakage of the atomized medium, in one embodiment, the surface of the bottom of the atomizing part 111 and / or the guiding part 112 is provided with a leakage-proof sealing layer, i.e. a sealing medium, in the direction of gravity. Further, in one embodiment, the leakage-proof sealing layer is a coating or a sheet. In one embodiment, the bottom of the atomizing part 111 and / or the guiding part 112 is covered with a medium that does not conduct oil, which can include a coating, a sealing member, and other non-oil-conducting materials, to prevent the atomized medium stored inside the atomizing part 111 and / or the guiding part 112 from leaking out of the atomizing core assembly 110. Further, in one embodiment, the leakage-proof sealing layer is provided on the guiding part 112 except for the liquid suction surface 119 and the portion that contacts the atomizing part 111, to prevent leakage of the atomized medium.

The atomizer further comprises a lower sealing member 220 for fixing the atomizing core and cooperating to seal the liquid storage cavity 260, in combination with Figure 16 , the lower sealing member 220 is further provided with an air inlet passage 221 communicating with the air inlet 243. Further, in one of the embodiments, the upper sealing member 210 is provided with a flow-through region 113 or the lower sealing member 220 is provided with an avoiding groove 114, so as to ensure that the air inlet can pass through and flow out of the two smoke passages at the same time, and the effect of gas flow-through can also be achieved.

[0079] In one of the embodiments, as shown in Figure 14 and Figure 15 The atomizing structure 100 further comprises a mounting member 160 and a sealing sleeve 170, the mounting member 160 is sleeved outside the lead wire of the guide part 112 and located in the lower sealing member 220, and the sealing sleeve 170 is sleeved outside the lower sealing member 220, or as shown in Figure 15 and Figure 17As shown, the sealing sleeve 170 is sleeved in the mounting groove 222 of the lower sealing member 220, and the mounting member 160, the lower sealing member 220 and the sealing sleeve 170 cooperate to tightly abut the lower sealing member 220 against the shell 240 to seal the liquid storage cavity 260, so that the atomization medium in the liquid storage cavity 260 only contacts the liquid suction surface 119 of the guide portion 112. In this embodiment, the lower sealing member 220 is sleeved outside the mounting member 160, and the sealing sleeve 170 is sleeved in the lower sealing member 220.

[0080] In one of the embodiments, the communication of the air passage is as shown in the following. Figure 15 As shown, the air passage 190 includes a first air passage 191, a second air passage 192 and a main air passage 193; the first air passage 191 and the second air passage 192 are both in fluid communication with the main air passage 193 for output. Further, there is a gap between the ventilation pipe 150 and the atomization portion 111 through the top portion 117 and the limiting step 118, so that the second air passage 192 realizes fluid communication with the main air passage 193 through the gap; that is, the pipe diameter of the ventilation pipe 150 and the atomization portion 111 can be the same or different, and the ventilation pipe 150 and the atomization portion 111 are arranged in non-contact, to form a space between the ventilation pipe 150 and the atomization portion 111, which can be part of the main air passage 193, so as to make the main air passage 193 communicate with the second air passage 192. This is an important point of the present application, which forms two atomization surfaces on the inner wall and the outer wall of the atomization portion 111, and the first air passage 191 and the second air passage 192, so as to have the advantage of large amount of atomized aerosol.

[0081] Further, as shown in the following. Figure 15 As shown, one end of the ventilation pipe 150 abuts against the limiting step 118 of the atomization core assembly 110 through the sealing upper cover 130, and abuts against the upper end of the guide portion 112 of the atomization core assembly 110; the limiting step 118 is arranged to cooperate to retain the fluid communication of the first air passage 191 and the second air passage 192 when the ventilation pipe 150 is installed. The above structure effectively avoids that the atomization medium in the liquid storage cavity 260 enters the atomization portion 111 from a position other than the liquid suction surface 119, and also avoids that the atomization medium mixes into the ventilation pipe 150 and the main air passage 193 therein, by the design of the sealing upper cover 130 and the connection relationship thereof.

[0082] Further, as shown in the following. Figure 15As shown, the vent pipe 150 penetrates the sealing upper cover 130 to make the main air passage 193 in the vent pipe 150 in fluid communication with the first air passage 191 and the second air passage 192 in the atomization core assembly 110. On one hand, the bottom of the atomization core assembly 110 abuts against the mounting member 160 and the lower sealing member 220, and through the lower sealing member 220, abuts against the sealing sleeve 170 and the shell 240. On the other hand, the outer wall of the guide portion 112 of the atomization core assembly 110 abuts against the lower sealing member 220, and through the lower sealing member 220, abuts against the shell 240, so that the shell 240 is tightly abutted against the lower sealing member 220 and the atomization core assembly 110, and the wires of the guide portion 112 are sealed and isolated from the liquid storage cavity 260, thereby achieving effective sealing of the end to the liquid storage cavity 260. In this embodiment, the main air passage 193 of the vent pipe 150 is in fluid communication with the first air passage 191, and the main air passage 193 is in fluid communication with the second air passage 192.

[0083] For the sealing of the liquid storage cavity 260, it has always been the focus of the field, and the present application is no exception. Since the vent pipe 150 penetrates the liquid storage cavity 260, it is necessary to consider solving the problem of sealing of both ends of the shell 240 and the liquid storage cavity 260. On one hand, the sealing upper cover 130 of the atomization structure 100, the vent pipe 150 and the atomization core assembly 110 cooperate with each other, and are tightly combined, so that the atomization medium in the liquid storage cavity 260 cannot leak into the first air passage 191 and the second air passage 192 in the atomization core assembly 110 through the gap between the vent pipe 150 and the sealing upper cover 130. On the other hand, the lower sealing member 220 cooperates with the sealing sleeve 170 and the mounting member 160 to apply pressure to one end of the shell 240, so that the shell 240 is tightly sleeved outside the atomization core assembly 110, and the whole constitutes a sealing system, so that the atomization medium in the liquid storage cavity 260 cannot leak out of the atomizer or leak out to the wires of the guide portion 112 through the gap between the mounting member 160, the sealing sleeve 170 and the shell 240. Such design achieves effective sealing of one end of the shell 240 and the liquid storage cavity 260.
