[0045] The embodiment of the present application provides an atomization device 100, which is used for heating an aerosol substrate and atomizing the aerosol substrate to form a mist. The atomization device 100 can be a disposable atomization device, or the atomization device 100 can also be a non-disposable atomization device.

[0046] Please refer to Figure 2 The atomization device 100 comprises an atomization core 1, which is fixedly arranged in the interior of the atomization device 100. The working principle of the atomization core 1 is to heat the heating element 11 in the atomization core 1 to the boiling point of the liquid aerosol substrate, so as to generate a mist.

[0047] In an embodiment, please refer to Figure 1 and Figure 2 The atomization device 100 further comprises a suction nozzle 2, a shell 3 and a bottom cover 4.

The interiors of the suction nozzle 2, the shell 3 and the bottom cover 4 form a containing cavity. Please refer to Figure 2 The atomization core 1 is located in the containing cavity formed by the suction nozzle 2, the shell 3 and the bottom cover 4.

[0048] In an embodiment, please refer to Figure 2 The atomization device 100 further comprises a battery 8. The battery 8 is located in the shell 3. The battery 8 is connected with the atomization core 1 and provides electric energy for the atomization core 1. The battery 8 can be a rechargeable battery or a non-rechargeable battery.

[0049] It should be noted that the atomization device 100 can comprise a power supply device and an atomizer respectively. The power supply device is arranged at one end of the atomizer and connected with the atomizer. The power supply device comprises the battery 8 and the like, and the atomizer comprises the suction nozzle 2 and the atomization core 1 and the like.

[0050] When the atomization device 100 is a disposable atomization device, the power supply device and the atomizer are usually connected in a non-detachable manner. When the power supply device and the atomizer are connected in a detachable manner, the atomizer and the power supply device can be sold separately.

[0051] Next, the structure of the atomization core 1 and the cooperation between the atomization core 1 and other components in the atomization device 100 will be mainly described.

[0052] In an embodiment, please refer to Figure 4 The atomization core 1 comprises a heating element 11 and a liquid storage pipe 12. The heating element 11 is connected with the liquid storage pipe 12. The heating element 11 is connected with the battery 8.

[0053] Please refer toFigure 4 The inner part of the liquid storage tube 12 is formed with a middle through hole 121, which is used for airflow flow. In one example, as shown in Figure 2 and Figure 3 The middle through hole 121 of the liquid storage tube 12 is connected with the suction nozzle 2, that is, the airflow flow channel 9 is formed between the liquid storage tube 12 and the suction nozzle 2, the inner side of the shell 3 and the outer side of the atomization core 1 are formed with a liquid storage chamber 10, which is used for storing liquid aerosol substrate, and the liquid aerosol substrate can permeate into the liquid storage tube 12. When the atomization core 1 is in working state, the temperature of the heating element 11 rises, and the heating element 11 can heat the aerosol substrate permeated through the liquid storage tube 12 to evaporate it. When the user inhales at the suction nozzle 2, there is airflow flow in the middle through hole 121, and the evaporated aerosol substrate forms mist under the condensation of airflow, and finally the mist flows to the suction nozzle 2 along with the airflow.

[0054] In one example, as shown in Figure 2 The atomization device 100 includes an upper sealing member 6, a lower sealing member 7, and a pipe 101. The upper sealing member 6 is in sealing cooperation with the inner side of the shell 3 and the suction nozzle 2. The lower sealing member 7 is arranged below the upper sealing member 6 and is in sealing cooperation with the inner side of the shell 3 and the atomization core 1. The inner part of the pipe 101 is formed with the airflow flow channel 9, and the liquid storage chamber 10 is formed between the upper sealing member 6 and the lower sealing member 7. Optionally, the upper sealing member 6 and the lower sealing member 7 are both made of silica gel.

[0055] In one example, as shown in Figure 3 The atomization device 100 further includes an atomization chamber shell 102, which is arranged on the inner side of the shell 3 and is in sealing cooperation with the upper sealing member 6 and the lower sealing member 7.

[0056] In one example, as shown in Figure 5 The heating element 11 includes a first lead 111, a second lead 112, and a heating zone 113. The two ends of the heating zone 113 are connected with the first lead 111 and the second lead 112, respectively. As shown in Figure 4 The heating zone 113 is located in the middle through hole 121, and the liquid storage tube 12 includes a first end 122 and a second end 123 opposite to each other. The free end of the first lead 111 and the free end of the second lead 112 both extend towards the first end 122.

[0057] In this example, the free end of the first lead 111 and the free end of the second lead 112 are used to connect with the battery 8, and the heating element 11 mainly plays a role of heating the aerosol substrate.

[0058] In one example, as shown in Figure 5 The heating zone 113 is in spiral shape.

[0061] In an example, referring to Figure 5 , the second pin 112 comprises a second spiral part 1121 and a second linear part 1122, the second spiral part 1121 connects the heating zone 113 and the second linear part 1122, and the second spiral part 1121 is in a spiral shape.

[0062] In an example, the second linear part 1122 is in an inverted L shape, referring to Figure 5 , the second linear part 1122 comprises a second radial segment 11221 and a second axial segment 11222, and the second radial segment 11221 connects the second axial segment 11222 and the second spiral part 1121.

[0063] The atomizing core 1 provided by the embodiments of the present application comprises two components, the heating element 11 and the liquid storage tube 12, and the components are simple in structure, which facilitates the processing and manufacturing of the atomizing core 1, reduces the cost of the atomizing core 1, and improves the production efficiency of the atomizing core.

[0064] As described above, the liquid aerosol substrate stored in the liquid storage tank 10 can permeate into the liquid storage tube 12, and regarding the liquid storage tube 12, in an embodiment, the material of the liquid storage tube 12 is porous fiber material.

[0065] In an example, the material of the liquid storage tube 12 is one of polypropylene (PP), polyethylene terephthalate (PET), polyamide (PA), etc.; or the material of the liquid storage tube 12 is a mixture of two or more of polypropylene (PP), polyethylene terephthalate (PET), polyamide (PA), etc., wherein the materials are mixed in different proportions.

[0066] In an example, the density of the liquid storage tube 12 ranges from 0.05 kg / m 3 to 0.5 kg / m 3For example, the density of the liquid storage tube 12 is 0.05-0.1 kg / m 3 , 0.1-0.2 kg / m 3 , 0.2-0.3 kg / m 3 , 0.3-0.4 kg / m 3 , 0.4-0.5 kg / m 3 , etc.

[0067] In an example, the porosity of the liquid storage tube 12 ranges from 50% to 80%, for example, the porosity of the liquid storage tube 12 is 50%-55%, 55%-60%, 60%-65%, 65%-70%, 70%-75%, 75%-80%, etc.

[0068] In this embodiment, the liquid storage tube 12 is a porous fiber material, which has the characteristics of good liquid guiding performance; in addition, the liquid storage tube 12 has high temperature resistance at the through hole 121, and the outer side wall of the liquid storage tube 12 has high hardness.

[0069] In an embodiment, please refer to Figure 5 , the heating area 113 is spiral, the heating area 113 includes two or more heating wires 1131, each heating wire 1131 is spiral, and the two ends of each heating wire 1131 are respectively connected with the first pin 111 and the second pin 112.

[0070] The heating area 113 includes two or more heating wires 1131, for example, the heating area 113 includes two or three or four or any number of heating wires 1131. Please refer to Figure 5 , which shows that the heating area 113 includes two heating wires 1131. When the heating element 11 passes through the current, the temperature of the heating wire 1131 rises, and then generates heat.

[0071] In this embodiment, the heating area 113 includes two or more heating wires 1131, so as to improve the atomization efficiency of the atomization core 1.

[0072] In an example, the material of the heating wire 1131 is nickel-chromium alloy or iron-chromium-aluminum alloy or copper-nickel alloy or molybdenum wire or tungsten wire.

[0073] In an example, the material of the heating wire 1131 is iron-nickel alloy or copper alloy.

[0074] In an example, one end of each heating wire 1131 is welded to the first pin 111; the other end of each heating wire 1131 is welded to the second pin 112.

[0075] Please refer to Figures 6-8 , Figure 6 the structure diagram of the atomization core 1 provided in the embodiment of the present application; Figure 7Another structural schematic diagram of the atomizing core 1 provided by an embodiment of the present application is shown in FIG. 2. Figure 8 A structural schematic diagram of the atomizing core 1 provided by another embodiment of the present application is shown in FIG. 3.

[0076] In one embodiment, the heating element 11 is inserted into the through hole 121 from the first end 122 or from the second end 123 of the liquid storage tube 12.

[0077] That is, in the atomizing core 1 provided by the embodiment, the liquid storage tube 12 and the heating element 11 are mounted in such a way that the heating element 11 is inserted into the through hole 121 of the liquid storage tube 12 from one end of the liquid storage tube 12. In one example, the heating element 11 can be arranged to be inserted into the through hole 121 from the first end 122, and in another example, the heating element 11 can be arranged to be inserted into the through hole 121 from the second end 123, so that the atomizing core 1 is simple to assemble.

[0078] In one embodiment, please refer to Figure 6 and Figure 7 An opening 124 is arranged on the circumferential side of the liquid storage tube 12, the two ends of the opening 124 are respectively open to the first end 122 and the second end 123, and the opening 124 is in communication with the through hole 121.

[0079] Specifically, since the heating element 11 needs to be in contact with the inner wall surface of the through hole 121 of the liquid storage tube 12, it is preferred that the outer diameter of the heating element 11 is slightly larger than the diameter of the through hole 121, so that the heating element 11 can abut on the inner side surface of the through hole 121. When the heating element 11 is inserted into the through hole 121 of the liquid storage tube 12 from one end of the liquid storage tube 12, the liquid storage tube 12 will be expanded through the opening 124, so that the inner diameter of the liquid storage tube 12 is increased to facilitate the insertion of the heating element 11 into the through hole 121 of the liquid storage tube 12.

[0080] Therefore, in the embodiment, the opening 124 is arranged on the liquid storage tube 12 to facilitate the installation of the heating element 11 on the liquid storage tube 12.

[0081] In one embodiment, the width of the opening 124 along the circumferential direction of the liquid storage tube 12 is 0.1mm-1mm.

[0082] It should be noted that the width of the opening 124 along the circumferential direction of the liquid storage tube 12 defined in the embodiment refers to the width value of the opening 124 along the circumferential direction of the liquid storage tube 12 when the heating element 11 is inserted into the through hole 121 of the liquid storage tube 12.

[0083] In an example, when the heating element 11 is not inserted into the middle through hole 121 of the liquid storage tube 12, the width of the gap 124 along the circumferential direction of the liquid storage tube 12 is greater than or equal to 0, for example, when the heating element 11 is not inserted into the middle through hole 121 of the liquid storage tube 12, the width of the gap 124 along the circumferential direction of the liquid storage tube 12 is 0.

[0084] The width of the gap 124 along the circumferential direction of the liquid storage tube 12 is 0.1mm-1mm, for example, the width of the gap 124 along the circumferential direction of the liquid storage tube 12 is 0.1mm-0.2mm, 0.2mm-0.3mm, 0.3mm-0.4mm, 0.4mm-0.5mm, 0.5mm-0.6mm, 0.6mm-0.7mm, 0.7mm-0.8mm, 0.8mm-0.9mm, 0.9mm-1mm, etc.

[0085] In this embodiment, by limiting the width of the gap 124 along the circumferential direction of the liquid storage tube 12, when the width of the gap 124 along the circumferential direction of the liquid storage tube 12 is too large, a large amount of aerosol will flow to the inside of the atomization core 1 through the gap 124.

[0086] In an example, please refer to Figures 6-8 , the first pin 111 is led out from the middle through hole 121 through the first end 122, and the second pin 112 extends along the radial direction of the liquid storage tube 12 and then extends along the outer side of the liquid storage tube 12 to the direction of the first end 122; in other examples, the second pin 112 is embedded in the liquid storage tube 12 and led out through the first end 122, and the first pin 111 extends along the radial direction of the liquid storage tube 12 and then extends along the outer side of the liquid storage tube 12 to the direction of the first end 122; in other examples, the first pin 111 extends along the radial direction of the liquid storage tube 12 and then extends along the outer side of the liquid storage tube 12 to the direction of the first end 122, and the second pin 112 extends along the radial direction of the liquid storage tube 12 and then extends along the outer side of the liquid storage tube 12 to the direction of the first end 122, and preferably, the first pin 111 and the second pin 112 are oppositely arranged along the radial direction of the liquid storage tube 12.

[0087] Hereinafter, the first pin 111 is led out from the middle through hole 121 through the first end 122, and the second pin 112 extends along the radial direction of the liquid storage tube 12 and then extends along the outer side of the liquid storage tube 12 to the direction of the first end 122. The first pin 111 and the second pin 112 are further described.

[0088] In the embodiment, as to the connection mode of the liquid storage tube 12 and the heating element 11, in one example, the heating element 11 is inserted into the through hole 121 from the second end 123 of the liquid storage tube 12, that is, the liquid storage tube 12 and the heating element 11 are assembled together after being heated; in other examples, the fixed connection of the liquid storage tube 12 and the heating element 11 is realized in the process of casting or pressure casting of the liquid storage tube 12, for example, when the fixed connection of the liquid storage tube 12 and the heating element 11 is realized in the process of casting of the liquid storage tube 12, the heating element 11 can be placed in the mold first, and then the casting is performed, and the fixed connection of the liquid storage tube 12 and the heating element 11 is realized after the liquid storage tube 12 is formed.

[0089] In the embodiment, the second pin 112 extends along the radial direction of the liquid storage tube 12 and then extends along the direction of the first end 122 of the outer side of the liquid storage tube 12, please refer to Figure 5 , it is shown that the second linear part 1122 of the second pin 112 includes a second radial segment 11221 and a second axial segment 11222, the second radial segment 11221 is the segment of the second pin 112 extending along the radial direction of the liquid storage tube 12, and the second axial segment 11222 is the segment of the second pin 112 extending along the direction of the first end 122 of the outer side of the liquid storage tube 12.

[0090] In the embodiment, the first pin 111 is led out from the through hole 121 through the first end 122, and the pin is fixed at the same time, so that the first pin 111 and the second pin 112 are prevented from being in contact to cause the heating element 11 to be short-circuited and unable to work.

[0091] When the heating element 11 is inserted into the through hole 121 from the second end 123 of the liquid storage tube 12, in one embodiment, please refer to Figure 7 , the second pin 112 extends along the radial direction of the liquid storage tube 12 after being stretched out from the second end 123.

[0092] Please refer to Figure 5 , in the embodiment, when the heating element 11 is inserted into the through hole 121 from the second end 123 of the liquid storage tube 12, the second linear part 1122 of the second pin 112 of the heating element 11 is located on the outer side of the liquid storage tube 12, and the first pin 111 faces the through hole 121, and the heating element 11 is inserted into the liquid storage tube 12 from the second end 123 of the liquid storage tube 12.

[0093] In one example, when the heating element 11 is inserted into the through hole 121 from the second end 123 of the liquid storage tube 12, the heating element 11 is inserted into position when the section of the second linear portion 1122 extending along the radial direction of the liquid storage tube 12 (i.e., the second radial section 11221) is in contact with the second end 123 of the liquid storage tube 12, at which time the second radial section 11221 of the second linear portion 1122 is in abutment with the outer side surface of the liquid storage tube 12, the heating zone 113 is in abutment with the inner side surface of the liquid storage tube 12, and the first helical portion 1111 and the first linear portion 1112 of the first lead 111 are in abutment with the inner side surface of the liquid storage tube 12.

[0094] The structure of the second lead 112 provided in this embodiment can facilitate insertion of the heating element 11 into the through hole 121 from the second end 123 of the liquid storage tube 12.

[0095] When the heating element 11 is inserted into the through hole 121 from the second end 123 of the liquid storage tube 12, in one embodiment, the circumferential side surface of the liquid storage tube 12 is provided with a relief opening, which is in communication with the through hole 121 and opens to the second end 123, and the section of the second lead 112 extending along the radial direction of the liquid storage tube 12 passes through the relief opening.

[0096] In this embodiment, when the heating element 11 is inserted into the through hole 121 from the second end 123 of the liquid storage tube 12, the second linear portion 1122 of the second lead 112 of the heating element 11 is located on the outer side surface of the liquid storage tube 12, and the first lead 111 faces the through hole 121, and during insertion of the heating element 11 into the liquid storage tube 12, the section of the second lead 112 extending along the radial direction of the liquid storage tube 12 (i.e., the second radial section 11221) can continue to move in the direction of insertion into the liquid storage tube 12 by passing through the relief opening.

[0097] That is, in this embodiment, by changing the length of the relief opening along the axial direction of the liquid storage tube 12, the depth of insertion of the heating element 11 into the through hole 121 from the second end 123 of the liquid storage tube 12 can be changed, and the length of the relief opening along the axial direction of the liquid storage tube 12 can be reasonably set according to requirements.

[0098] When the circumferential side surface of the liquid storage tube 12 is provided with the aperture 124, in one example, the relief opening and the aperture 124 are located at different positions on the liquid storage tube 12; in other examples, the relief opening and the aperture 124 are the same structure, i.e., it can be understood that the aperture 124 on the circumferential side surface of the liquid storage tube 12 is also used to form the relief opening, and the section of the second lead 112 extending along the radial direction of the liquid storage tube 12 (i.e., the second radial section 11221) can be inserted into the aperture 124.

[0099] When the liquid storage tube 12 is cast or die-cast to achieve fixed connection with the heating element 11, in one embodiment, see Figure 8 , the outer circumferential side of the liquid storage tube 12 is provided with a plug hole 125, which is in communication with the middle through hole 121, and the second pin 112 passes through the plug hole 125 to pass through the liquid storage tube 12, that is, the second radial section 11221 of the second pin 112 passes through the plug hole 125.
