[0045] Referring to FIG. 1 , an embodiment of the present invention provides an atomizing device 20 that can store an aerosol-generating substrate and heat and atomize the stored aerosol-generating substrate into an aerosol. The aerosol-generating substrate is a liquid, and may include, but is not limited to, materials used for medical, health, wellness, and cosmetic purposes, such as a liquid medicine or an oil. The following embodiments primarily illustrate the example of the atomizing device 20 heating and atomizing the aerosol-generating substrate. Other situations requiring the atomizing device 20 may be implemented accordingly.

[0046] 1 and 2 , the atomizer device 20 may include a housing 400 and an atomizer core 10. The atomizer core 10 may heat and atomize an aerosol-generating substrate stored in the atomizer device 20 into an aerosol. The atomizer core 10 may be mounted within the housing 400 so that the housing 400 protects the atomizer core 10.

[0047] The housing 400 may be provided with an oil storage chamber 401 for accommodating an aerosol-generating substrate. The oil storage chamber 401 may be disposed around the periphery of the atomizer core 10, thereby increasing the contact area between the aerosol-generating substrate stored in the oil storage chamber 401 and the atomizer core 10, thereby further facilitating the provision of the aerosol-generating substrate required for heating and atomization to the atomizer core 10.

[0048] Referring to FIG. 3 , the atomizer 20 may include an oil-storage cotton 402 , which may be mounted within the oil reservoir 401 to absorb the aerosol-forming substrate within the reservoir 401 , thereby enabling the oil-storage cotton 402 to store and lock in the oil. The oil-storage cotton 402 may be positioned around the atomizer core 10 , thereby increasing the contact area between the oil-storage cotton 402 and the atomizer core 10 and enabling the oil-storage cotton 402 to quickly provide the atomizer core 10 with sufficient aerosol-forming substrate.

[0049] Referring to FIG. 2 , the present invention provides an atomizer core 10 . The atomizer core 10 can be used in an atomizer device 20 . The atomizer core 10 can heat an aerosol-generating substrate within the atomizer device 20 . The following embodiments primarily illustrate the application of the atomizer core 10 in the atomizer device 20 . Other implementations requiring the atomizer core 10 can be referenced accordingly.

[0050] Please refer to Figures 1 to 7. The atomizer core 10 may include an atomizer bracket 100 and an inner cotton bag 200. The atomizer bracket 100 may have an atomization channel 101. The atomizer bracket 100 may be provided with an inner annular wall 102, an outer annular wall 103 and an oil inlet hole 104. The outer annular wall 103 may be arranged opposite to the inner annular wall 102, and the inner annular wall 102 may be arranged around the atomization channel 101. The oil inlet hole 104 may pass through the inner annular wall 102 and the outer annular wall 103. The inner cotton bag 200 is arranged in an annular shape. The inner cotton bag 200 is located in the atomization channel 101. The inner annular wall 102 is arranged around the outer circumference of the inner cotton bag 200. The inner cotton bag 200 may be opposite to the oil inlet hole 104. The splicing of the inner cotton bag 200 may abut against the atomizer bracket 100 and avoid the oil inlet hole 104. In this way, because the joint of the inner cotton 200 can abut against the atomizer bracket 100 and avoid the oil inlet hole 104, the atomizer bracket 100 can support the joint of the inner cotton 200, preventing the joint of the inner cotton 200 from collapsing from the oil inlet hole 104, thereby allowing the inner cotton 200 to operate normally. In addition, the joint of the inner cotton 200 avoiding the oil inlet hole 104 also helps prevent the aerosol-generating substrate stored in the atomizer device 20 from directly leaking from the joint of the inner cotton 200 into the atomization channel 101.

[0051] It can be understood that the inner cotton 200 is arranged in a ring shape, that is, the two ends of the inner cotton 200 along the length direction are spliced ​​together. For example, the end faces of the two ends of the inner cotton 200 along the length direction can abut against each other. For another example, the end faces of the two ends of the inner cotton 200 along the length direction can abut against each other, and then can be reinforced by needle and thread to improve the connection firmness of the two ends, so that the inner cotton 200 becomes a ring structure.

[0052] Referring to Figures 4 to 6, the atomizer core 10 may further include a heating element 300, which, when powered on, can heat the aerosol-generating substrate and atomize it into an aerosol. The heating element 300 can be electrically connected to the power supply via electrode pins. The heating element 300 can be located within the atomization channel 101, and the inner cotton 200 can surround and abut against the outer periphery of the heating element 300, so that the heating element 300 can be wrapped by the inner cotton 200, which helps to increase the contact area between the inner cotton 200 and the heating element 300. The inner cotton 200 can provide the heating element 300 with sufficient aerosol-generating substrate, thereby helping the heating element 300 to heat and atomize the aerosol-generating substrate into an aerosol. There are many options for the heating element 300. For example, the heating element 300 can be a heating coil; for another example, the heating element 300 can be a ceramic heating element.

[0053] There are many options for the manufacturing material of the atomizer bracket 100. For example, the atomizer bracket 100 can be made of stainless steel, so that the atomizer bracket 100 has greater strength and hardness; for another example, the atomizer bracket 100 can be made of brass, so that the atomizer bracket 100 has better anti-rust and anti-corrosion properties.

[0054] The atomizing bracket 100 may be an annular structure, so that the atomizing channel 101 is roughly cylindrical, thereby making it less likely for the atomizing bracket 100 to hinder the installation of the inner cotton 200, helping the inner cotton 200 to be installed more smoothly in the atomizing channel 101, and further helping the inner cotton 200 to be quickly assembled in the atomizing channel 101 of the atomizing bracket 100. In addition, the inner annular wall 102 of the atomizing bracket 100 may be annular, and the inner cotton 200 may be tightly attached to the inner annular wall 102 of the atomizing bracket 100, so that the inner cotton 200 can relatively tightly block the oil inlet hole 104, thereby helping to reduce the risk of the aerosol-generating matrix stored in the oil storage chamber 401 leaking into the atomizing channel 101.

[0055] In one embodiment, the oil storage chamber 401 can be opposite to the oil inlet hole 104, so that the oil inlet hole 104 can be connected to the oil storage chamber 401, thereby facilitating the aerosol generating matrix stored in the oil storage chamber 401 to flow from the oil inlet hole 104 to the inner cotton bag 200, thereby helping the inner cotton bag 200 to absorb the aerosol generating matrix, so as to provide the heating element 300 with the aerosol generating matrix required for heating and atomization.

[0056] Please refer to Figures 2 and 4 to 7. In one embodiment, there can be multiple oil inlet holes 104, so that the aerosol generating substrate stored in the oil storage chamber 401 can flow to the inner cotton bag 200 from multiple oil inlet holes 104 at the same time, which helps to make the aerosol generating substrate stored in the oil storage chamber 401 flow to the inner cotton bag 200 quickly, thereby helping to improve the efficiency of the aerosol generating substrate stored in the oil storage chamber 401 flowing to the inner cotton bag 200.

[0057] Referring to Figure 7 , the atomizer holder 100 can have multiple supporting sidewalls 110. Each supporting sidewall 110 can be provided between two adjacent oil inlet holes 104, and the joint of the inner cotton wadding 200 abuts against one of the supporting sidewalls 110. Thus, having multiple supporting sidewalls 110 facilitates easier alignment of the joint of the inner cotton wadding 200 with one of the supporting sidewalls 110, allowing the inner cotton wadding 200 to be accurately and quickly assembled into the atomizing channel 101 of the atomizer holder 100, and facilitates operation.

[0058] In one embodiment, the atomizing bracket 100 may further be provided with an oil storage chamber communicating hole 105. The oil storage chamber communicating hole 105 may be a circular hole or a square hole, etc. The oil storage chamber communicating hole 105 may penetrate the inner annular wall 102 and the outer annular wall 103, and the oil storage chamber communicating hole 105 is connected to the atomizing channel 101. For example, the oil storage chamber communicating hole 105 may be connected to the oil storage chamber 401 and the atomizing channel 101, so that the oil storage chamber 401 can be connected to the atomizing channel 101, so that the oil storage chamber 401 can exchange air with the atomizing channel 101 through the oil storage chamber communicating hole 105, and the oil storage chamber 401 is prevented from experiencing a significant change in air pressure due to changes in the content of the aerosol-generating substrate stored in the oil storage chamber 401, thereby helping to reduce the risk of the aerosol-generating substrate having difficulty flowing to the inner cotton packing 200 due to a drop in air pressure in the oil storage chamber 401, thereby helping the aerosol-generating substrate stored in the oil storage chamber 401 to flow normally to the inner cotton packing 200. Of course, the size of the oil storage cavity communication hole 105 should not be too large, so as to help prevent the aerosol-generating substrate stored in the oil storage cavity 401 from leaking from the oil storage cavity communication hole 105 to the atomization channel 101 .

[0059] In one embodiment, the diameter of the oil storage cavity communication hole 105 is 0.1 mm to 0.5 mm. For example, the oil storage cavity communication hole 105 may be a circular through hole, and the diameter of the oil storage cavity communication hole 105 is equal to the diameter of the oil storage cavity communication hole 105; for another example, the oil storage cavity communication hole 105 may be a square through hole, and the diameter of the oil storage cavity communication hole 105 is equal to the width of the oil storage cavity communication hole 105; for another example, the oil storage cavity communication hole 105 may be an irregularly shaped through hole, and the diameter of the oil storage cavity communication hole 105 is equal to the width of the oil storage cavity communication hole 105.

[0060] The diameter of the oil reservoir communicating hole 105 can be, but is not limited to, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, or 0.5 mm. By keeping the diameter of the oil reservoir communicating hole 105 within the aforementioned range, the aerosol-forming substrate stored in the oil reservoir 401 can be prevented from leaking from the oil reservoir communicating hole 105 into the atomizing passage 101, while also facilitating air exchange between the oil reservoir 401 and the atomizing passage 101.

[0061] In one embodiment, the oil storage chamber communication hole 105 may be located above the oil inlet hole 104. For example, when the aerosol-generating substrate is loaded into the oil storage chamber 401, the liquid level of the aerosol-generating substrate may be located below the oil storage chamber communication hole 105. For example, the liquid level of the aerosol-generating substrate may be located between the oil storage chamber communication hole 105 and the oil inlet hole 104. For another example, the liquid level of the aerosol-generating substrate may be located at the oil inlet hole 104. In this way, when the user uses and holds the atomizer 20 normally, the oil storage chamber connecting hole 105 is located above the oil inlet hole 104, and the aerosol generating matrix stored in the oil storage chamber 401 flows from the oil inlet hole 104 to the inner cotton 200. The space above the aerosol generating matrix in the oil storage chamber 401 can be exchanged with the air in the atomization channel 101, avoiding the aerosol generating matrix stored in the oil storage chamber 401 from blocking the oil storage chamber connecting hole 105, thereby ensuring that the oil storage chamber 401 can exchange air with the atomization channel 101 through the oil storage chamber connecting hole 105.

[0062] In one embodiment, the oil storage chamber communication hole 105 is disposed adjacent to the inner cotton 200. For example, because the oil storage chamber communication hole 105 is disposed adjacent to the inner cotton 200, the area within the oil storage chamber 401 adjacent to the inner cotton 200 can more quickly exchange air with the atomization channel 101, thereby facilitating faster flow of the aerosol-generating substrate stored in the oil storage chamber 401 and adjacent to the inner cotton 200 toward the inner cotton 200.

[0063] Please refer to Figure 7. In one embodiment, the oil storage chamber connecting hole 105 is connected to the oil inlet hole 104 along the length direction of the atomizer bracket 100, so that the oil storage chamber connecting hole 105 and the oil inlet hole 104 of the atomizer bracket 100 can be continuously processed during processing and production, so that the operator can complete the processing of the oil storage chamber connecting hole 105 and the oil inlet hole 104 of the atomizer bracket 100 by positioning and calibrating the turning tool once, thereby helping to reduce the steps of turning the atomizer bracket 100, and further helping to improve the processing efficiency of the atomizer bracket 100.

[0064] Please refer to Figures 8 to 11. In one embodiment, the atomizing bracket 100 is recessed from the outer ring wall 103 toward the inner ring wall 102 to form an oil storage chamber connecting groove 106. The oil storage chamber connecting groove 106 is connected to the oil inlet hole 104. The connecting part between the oil storage chamber connecting groove 106 and the oil inlet hole 104 is connected to the atomizing channel 101. The inner cotton packing 200 avoids the connecting part between the oil storage chamber connecting groove 106 and the oil inlet hole 104 and the atomizing channel 101. In this way, the oil storage chamber 401 can exchange air with the atomizing channel 101 through the connection between the oil storage chamber connecting groove 106 and the oil inlet hole 104 and the atomizing channel 101, so that the oil storage chamber does not experience a significant change in air pressure due to changes in the content of the aerosol-generating substrate stored in the oil storage chamber, thereby helping to reduce the risk of the aerosol-generating substrate having difficulty flowing to the inner cotton packing 200 due to a drop in air pressure in the oil storage chamber 401, and further helping the aerosol-generating substrate stored in the oil storage chamber 401 to flow normally to the inner cotton packing 200. Of course, the size of the connection between the oil storage chamber connecting groove 106 and the oil inlet hole 104 and the atomizing channel 101 should not be too large, thereby helping to prevent the aerosol-generating substrate stored in the oil storage chamber 401 from leaking from the connection between the oil storage chamber connecting groove 106 and the oil inlet hole 104 and the atomizing channel 101 to the atomizing channel 101.

[0065] In one embodiment, the connection point between the oil storage chamber connecting groove 106 and the oil inlet hole 104 and the atomizing channel 101 is adjacent to the end face of the upper end of the inner cotton 200. For example, since the ends of the inner cotton 200 can be spliced ​​into a ring-shaped arrangement, the inner cotton 200 is roughly annular in structure, and the two ends of the inner cotton 200 along the axial direction can respectively have a connected upper end and a lower end. When the user normally holds and uses the atomizing device, the upper end is located above the lower end. When the aerosol generating matrix is ​​loaded into the oil storage chamber 401, the liquid level of the aerosol generating matrix can be located below the connection point between the oil storage chamber connecting groove 106 and the oil inlet hole 104 and the atomizing channel 101. In this way, when the user uses and holds the atomizer 20 normally, the aerosol generating matrix stored in the oil storage chamber 401 will not block the connection between the oil storage chamber connecting groove 106 and the oil inlet hole 104 and the atomization channel 101, so that the space above the aerosol generating matrix in the oil storage chamber 401 can be exchanged with the air in the atomization channel 101, thereby ensuring that the oil storage chamber 401 can exchange air through the connection between the oil storage chamber connecting groove 106 and the oil inlet hole 104 and the atomization channel 101.

[0066] In addition, since the connection between the oil storage chamber connecting groove 106 and the oil inlet hole 104 and the atomization channel 101 is adjacent to the end face of the upper end portion of the inner cotton 200, when the aerosol generating matrix stored in the oil storage chamber 401 leaks from the connection between the oil storage chamber connecting groove 106 and the oil inlet hole 104 to the atomization channel 101, the inner cotton 200 can absorb the aerosol generating matrix flowing through the connection between the oil storage chamber connecting groove 106 and the oil inlet hole 104 and the atomization channel 101, thereby helping to reduce the risk of the aerosol generating matrix stored in the oil storage chamber 401 leaking from the connection between the oil storage chamber connecting groove 106 and the oil inlet hole 104 and the atomization channel 101.

[0067] The atomizer core 10 may further include a fixed base 600, which may be mounted within the atomizing channel 101 of the atomizer support 100. For example, the fixed base 600 may have an interference fit with the atomizer support 100; or, for another example, the fixed base 600 may be threadedly connected to the atomizer support 100. The fixed base 600 may secure the electrode pins of the heater 300, thereby helping to reduce the risk of the heater 300 becoming loose.

[0068] The atomizing device 20 may further include a nozzle 500 , which may be connected to the housing 400 . The nozzle 500 may be located at the top of the housing 400 . The nozzle 500 may be provided with a through hole connected to the atomizing channel 101 , so that a user may inhale the aerosol in the atomizing channel 101 through the nozzle 500 .
