[0032] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0033] See also Figures 1 to 6The embodiment of the present invention provides a heating element 10, an atomizing device 103 and an atomizing device 100. The atomizing device 100 includes a housing 101, a power supply assembly 102 and an atomizing device 103. The power supply assembly 102 and the atomizing device 103 are both arranged in the housing 101. The atomizing device 103 includes a heating element 10 and a fixing assembly 20. The heating element 10 is connected to the fixing assembly 20, and the fixing assembly 20 is connected to the housing 101. The power supply assembly 102 is used to supply power to the heating element 10. The aerosol product 200 is placed in the heating element 10. When the heating element 10 is energized, it generates heat, which can heat the aerosol product 200 located therein to generate an aerosol.

[0034] See also Figures 2 to 5 The heating element 10 includes a heating element base 11 and a heating circuit body 12. The heating element base 11 has a receiving cavity 111 and an opening 112 connected to the receiving cavity 111. The receiving cavity 111 is used to receive the aerosol product 200. The opening 112 is used for inserting the aerosol product 200 into the receiving cavity 111. The heating circuit body 12 is connected to the heating element base 11. The power supply component 102 is used to supply power to the heating circuit body 12. The heating element base 11 has thermal conductivity. The heat generated by the heating circuit body 12 after being energized can be transferred to the receiving cavity 111 through the heating element base 11 to heat the aerosol product 200 located in the receiving cavity 111. In a specific implementation, the aerosol product 200 is inserted into the receiving cavity 111 through the opening 112, and the power supply component 102 is controlled to supply power to the heating circuit body 12, thereby heating the aerosol product 200.

[0035] The heating element base 11 can be made of a high thermal conductivity material, such as aluminum alloy, copper, alumina, etc. By using a high thermal conductivity material to prepare the heating element base 11, the thermal conductivity of the heating element base 11 is improved, and the heat generated by the heating circuit is transferred to the accommodating cavity 111 as much as possible, thereby reducing heat energy loss.

[0036] See also Figure 5 and Figure 6 The heating element base 11 includes a main body 113 and a bottom wall 114. The main body 113 is a hollow tubular structure, including a first end and a second end arranged opposite to each other. The bottom wall 114 is connected to the first end of the main body 113 and is enclosed with the main body 113 to form a accommodating cavity 111. The second end of the main body 113 has an opening 112.

[0037] The aerosol product 200 is generally cylindrical, and the main body 113 is configured as a tubular structure to facilitate insertion of the aerosol product 200 into the accommodating cavity 111. Of course, in specific applications, the main body 113 is not limited to being configured as a tubular structure, and can also be configured as other shapes to ensure that the heating element substrate 11 and the aerosol product 200 are compatible.

[0038] See also Figure 5 and Figure 6 The heating circuit body 12 has a sleeve-shaped sleeve portion 121, and the heating element 10 also includes a heat shrink tube 13. The sleeve portion 121 and the heat shrink tube 13 are both sleeved on the periphery of the main body 113, and the sleeve portion 121 is clamped between the main body 113 and the heat shrink tube 13. The heat shrink tube 13 is used to apply a fixing force to the heating circuit body 12 from the circumferential side of the sleeve portion 121 to prevent the heating circuit body 12 from separating from the main body 113.

[0039] By setting the sleeve portion 121 of the heating circuit body 12 to be sleeved on the periphery of the main body 113, the heating circuit body 12 is not connected to the main body 113 using a thick film process, but is pre-prepared and then sleeved on the periphery of the main body 113. The heating circuit body 12 is pre-prepared using a non-thick film process, which can avoid the situation where the thickness or width of different sections caused by the thick film process is inconsistent, thereby ensuring the consistency of the circuit body as a whole. In addition, a heat shrink tube 13 is sleeved on the periphery of the main body 113, so that the sleeve portion 121 is clamped between the main body 113 and the heat shrink tube 13. The heat shrink tube 13 applies a fixing force to the heating circuit body 12 from the circumferential side of the sleeve portion 121, thereby fixing the heating circuit body 12, thereby preventing the heating circuit body 12 from detaching from the heating body base 11. Therefore, the heating body 10 provided in this embodiment improves the consistency of the heating circuit body 12 and ensures the stability of the installation of the heating circuit body 12.

[0040] See also Figure 2 and Figure 5 The heating circuit body 12 also includes a power pin 122 , one end of which is electrically connected to the socket portion 121 , and the other end is used to electrically connect to the power supply component 102 , so that the power supply component 102 can supply power to the heating circuit body 12 .

[0041] In one embodiment, the heat shrink tubing 13 is made of a polyolefin material. The heat shrink tubing 13 is designed to shrink and deform when heated, thereby applying a securing force to the sleeve portion 121. By utilizing the heat shrinking property of the heat shrink tubing 13, the heating circuit 12 can be effectively secured. Furthermore, the heat shrink tubing 13 is flexible, flame-retardant, and insulative and corrosion-resistant, effectively protecting the heating circuit 12.

[0042] See also Figure 3 、 Figure 5 and Figure 6A guide groove 1131 is provided on the inner side of the main body 113. The guide groove 1131 is connected to the opening 112. The opening 112 is also used to allow external gas to pass through and flow into the guide groove 1131. The guide groove 1131 is used to guide the gas from the opening 112 to the bottom wall 114. In this way, the gas outside the heating element 10 flows through the opening 112 and the guide groove 1131 in sequence to the bottom wall 114, that is, to the end of the aerosol product 200. In specific implementation, when the airflow passes through the guide groove 1131, the heating element base 11 can heat the airflow passing through it, making the airflow flowing to the end of the aerosol product 200 a hot airflow, thereby heating the aerosol product 200. By providing the guide groove 1131 to guide the flow of gas, the heating efficiency of the aerosol product 200 is greatly improved compared to the technical solution without the guide groove 1131.

[0043] See also Figure 3 and Figure 6 The inner wall of the main body 113 has multiple protrusions 1132 extending axially thereof. Adjacent protrusions 1132 have gaps therebetween, forming guide grooves 1131 therebetween. These protrusions 1132 are designed to contact the periphery of the aerosol product 200 when the aerosol product 200 is inserted into the accommodating cavity 111. In this way, the main body 113 can heat the airflow passing through the guide grooves 1131 and, through contact with the aerosol product 200, directly heat the periphery of the aerosol product 200, thereby improving the heating efficiency of the aerosol product 200.

[0044] In one embodiment, the plurality of protrusions 1132 are arranged at equal intervals along the circumference of the main body 113, that is, the plurality of guide grooves 1131 are arranged at equal intervals along the circumference of the main body 113. This allows the airflow flowing from the guide grooves 1131 to the bottom wall 114 to be evenly distributed along the circumference of the aerosol product 200. Furthermore, the airflow flowing through the guide grooves 1131 toward the ends of the aerosol product 200 can be evenly heated. Furthermore, the plurality of protrusions 1132 can evenly heat the outer circumference of the aerosol product 200.

[0045] See also Figure 3 and Figure 6A stopper 1141 is provided on the side of the bottom wall 114 facing the accommodating cavity 111. Specifically, the stopper 1141 is provided on the inner side of the bottom wall 114. The stopper 1141 is configured to abut against the end of the aerosol product 200, thereby forming an airflow channel 115 between the aerosol product 200 and the bottom wall 114 when the aerosol product 200 is inserted into the accommodating cavity 111. The end of the guide groove 1131 away from the opening 112 is connected to the airflow channel 115, allowing airflow from the opening 112 to be guided into the airflow channel 115 via the guide groove 1131. With this arrangement, the opening 112, the guide groove 1131, and the airflow channel 115 form an air inlet channel, through which airflow can flow from the exterior of the heating element 10 to the end of the aerosol product 200, and then into the aerosol product 200.

[0046] In one embodiment, a mounting groove 1133 is defined on the outer side of the main body 113, and the sleeve portion 121 is mounted within the mounting groove 1133. By mounting the sleeve portion 121 within the mounting groove 1133, the stability of the connection between the heating circuit 12 and the heating element base 11 can be improved. Of course, in other embodiments, the main body 113 may not be provided with the mounting groove 1133.

[0047] In one embodiment, the heating circuit body 12 includes a group of sub-heating circuit bodies 12a, which can cover the smoke-generating section of the aerosol product 200. It is understood that in other embodiments, the heating circuit may also include at least two groups of sub-heating circuit bodies 12a. In specific implementations, the at least two groups of sub-heating circuit bodies 12a may be arranged along the axial direction of the main body 113 or around the circumference of the main body 113.

[0048] In one embodiment, the heating circuit is produced by laser cutting. The laser cutting process has high precision and effectively ensures the consistency of the entire circuit. It is understood that in other embodiments, the heating circuit can also be produced by stamping or machining.

[0049] In one embodiment, the second end of the main body 113 is connected to the fixing assembly 20, so that the heating element 10 is suspended from the fixing assembly 20. This arrangement, on the one hand, reduces the contact area between the heating element 10 and the fixing assembly 20, thereby reducing heat loss. On the other hand, a gap is created between the heating element 10 and the fixing assembly 20, and gas is located within this gap. Due to the poor thermal conductivity of gas, heat loss can be further reduced.

[0050] In one embodiment, the heating element base 11 further includes a flange 116, which is disposed at the second end of the main body 113 and surrounds the circumference of the main body 113. The flange 116 is connected to the fixing assembly 20 so that the heating element 10 is suspended and connected to the fixing assembly 20. Of course, in specific applications, the heating element base 11 may not be provided with the flange 116.

[0051] See also Figure 3 and Figure 6 The fixing assembly 20 includes a first sleeve 21 and a second sleeve 22. The first sleeve 21 includes a coaxially arranged first cylinder 211 and a first inner shrinkage tube 212, the first inner shrinkage tube 212 shrinks inward from one end or the interior of the first cylinder 211, and the second sleeve 22 includes a coaxially arranged second cylinder 221 and a second inner shrinkage tube 222, the second inner shrinkage tube 222 shrinks inward from one end or the interior of the second cylinder 221. The first cylinder 211 is connected to one end of the second cylinder 221, the first inner shrinkage tube 212 extends into the second cylinder 221, and extends in a direction close to the second inner shrinkage tube 222, the second end of the main body 113 is connected between the first inner shrinkage tube 212 and the second inner shrinkage tube 222, and the heating element base 11 is suspended in the second sleeve 22. In this way, the heating element 10 is suspended and connected to the fixing assembly 20. In specific implementation, the flange 116 is supported on the second inner shrinkage tube 222, and the first inner shrinkage tube 212 is located above the flange 116, that is, the flange 116 is clamped between the first inner shrinkage tube 212 and the second inner shrinkage tube 222. Such an arrangement can improve the firmness of the connection between the heating element 10 and the fixing component 20.

[0052] See also Figure 3 The atomizing device 103 further includes a base 30, which is connected to an end of the second barrel 221 away from the first barrel 211. The first sleeve 21, the second sleeve 22 and the base 30 all play a heat insulation role, which can reduce heat energy loss.

[0053] The heating element 10, atomizing device 103, and atomizing apparatus 100 provided in this embodiment utilize a prefabricated heating circuit 12 that is sleeved around the periphery of the main body 113 to achieve connection with the heating element base 11. Because the heating circuit 12 is not manufactured using a thick film process, the inconsistent thickness or width of different sections that would occur using a thick film process is avoided, thereby improving the consistency of the heating circuit 12.

[0054] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, modifications or substitutions can be made based on the concept of the present invention.
