Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.
[0036] 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).
[0037] 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.
[0038] See also Figures 2 to 5 The heating element 10 includes a heating element base 11 and a heating circuit 12. The heating element base 11 is provided with a receiving cavity 111 and an entrance and exit 112 connected to the receiving cavity 111. The receiving cavity 111 is used to receive the aerosol product 200, and the entrance and exit 112 is used for the aerosol product 200 to pass through so as to be inserted into or removed from the receiving cavity 111. The heating circuit 12 is provided in the area opposite to the heating element base 11 and the entrance and exit 112, and is used to generate heat when energized. Among them, the power supply component 102 is used to supply power to the heating circuit 12. The heating element base 11 has thermal conductivity. The heat generated by the heating circuit 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.
[0039] Using the above technical solution, by providing a accommodating cavity 111 and an entrance and exit 112 communicating with the accommodating cavity 111, the aerosol product 200 can be introduced into and out of the accommodating cavity 111 through the entrance and exit 112. Typically, the aerosol product 200 is cylindrical. When the aerosol product 200 is inserted into the accommodating cavity 111 through the entrance and exit 112, its end corresponds to the region of the heating element base 11 opposing the entrance and exit 112. By arranging the heating circuit 12 in the region of the heating element base 11 opposing the entrance and exit 112, the heat generated by the heating circuit 12 when energized can quickly heat the gas at the end of the aerosol product 200. Because the heating circuit 12 is only provided in the region of the heating element base 11 opposing the entrance and exit 112, i.e., the heating circuit 12 is provided in a portion of the heating element base 11, the heating element 10 is locally heated. This reduces heat loss in the heating element 10 compared to a system that provides overall heating (i.e., the heating circuit 12 is arranged throughout the entire region of the heating element base 11).
[0040] In a specific implementation, 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 12 is transferred to the accommodating cavity 111 as much as possible, thereby reducing heat energy loss.
[0041] See also Figures 3 to 5 The heating element base 11 includes a main body 113 and a bottom wall 114. The main body 113 is a tubular structure with a first end and a second end disposed opposite each other. The inlet 112 is located at the first end of the main body 113. The bottom wall 114 is connected to the second end of the main body 113. The main body 113 and the bottom wall 114 together form a receiving chamber 111. In a specific implementation, the diameter of the main body 113 matches that of the aerosol product 200, so that the aerosol product 200 can be securely accommodated in the receiving chamber 111.
[0042] The heating circuit 12 is located on the bottom wall 114. When the aerosol product 200 is inserted into the accommodating chamber 111, the end of the aerosol product 200 aligns with the bottom wall 114. Placing the heating circuit 12 on the bottom wall 114 rapidly heats the gas at the end of the aerosol product 200. Furthermore, when the atomizing device 100 is in use, the first end of the main body 113 is located above the second end, meaning the bottom wall 114 is located below. Heat moves upward, so locating the heating circuit 12 on the bottom wall 114 allows the heat generated by the heating circuit 12 when powered to move upward, allowing it to be more fully utilized to heat the aerosol product 200, improving heat utilization and reducing heat loss.
[0043] In one embodiment, the heating circuit 12 is arranged on the side of the bottom wall 114 facing away from the accommodating cavity 111, that is, the heating circuit 12 is arranged on the outside of the bottom wall 114. In a specific implementation, the heating circuit 12 is electrically connected to the power supply component 102, and the power supply component 102 supplies power to the heating circuit 12 so that the heating circuit 12 can generate heat. By arranging the heating circuit 12 on the outside of the bottom wall 114, it is conducive to achieving the electrical connection between the heating circuit 12 and the power supply component 102, and arranging the heating circuit 12 on the outside of the bottom wall 114 also makes the operation of the assembler more convenient and quick. Of course, in other embodiments, the heating circuit 12 can also be arranged on the side of the bottom wall 114 facing the accommodating cavity 111, or arranged inside the bottom wall 114.
[0044] See also Figure 2 、 Figure 4 and Figure 6The heating circuit 12 includes a circuit body 121 and two heating ends 122. The heating ends 122 are arranged on opposite sides of the bottom wall 114. The two ends of the circuit body 121 are respectively connected to the two heating ends 122, and the circuit body 121 is bent. Among them, the two heating ends 122 are used to connect to the power pins (not shown), thereby realizing the electrical connection between the heating circuit 12 and the power supply component 102. In a specific implementation, the circuit body 121 is bent so that the heating circuit 12 can cover the entire bottom wall 114, so that the corresponding accommodating cavity 111 parts of the bottom wall 114 can be heated, and thus the various parts of the end of the aerosol product 200 can be heated at the same time. It should be noted that the shape formed by the bending of the circuit body 121 is not limited, and can be Figure 6 The shape shown can also be other shapes. In this embodiment, the heating circuit 12 is provided in one group. It can be understood that in other embodiments, the heating circuit 12 can be provided in at least two groups.
[0045] In one embodiment, the heating circuit 12 is provided on the heating element substrate 11 by thick film printing. In specific implementation, it can be metal thick film printing or ceramic thick film printing.
[0046] The heating circuit 12 is printed on the heating element base 11 using a thick film printing process. Due to the process characteristics of the thick film printing process itself, the heating circuit 12 is layered and is constructed as an integrated structure with the heating element base 11. Compared with the technical solution of arranging the heating circuit 12 separately on the heating element base 11, it saves assembly steps, thereby improving the assembly efficiency of the heating element 10, and the integrated structure also enhances the connection firmness between the heating circuit 12 and the heating element base 11.
[0047] See also Figure 3 and Figure 4 The heating element base 11 is provided with a plurality of guide grooves 115 connected to the inlet and outlet 112 on the side facing the accommodating cavity 111. The inlet and outlet 112 are also used for gas to pass through and flow into the guide grooves 115. The guide grooves 115 are used to guide the gas from the inlet and outlet 112 to the end of the aerosol product 200. Among them, the guide grooves 115 are provided on the side of the main body 113 facing the accommodating cavity 111, that is, the guide grooves 115 are provided on the inner side of the main body 113. Such a configuration allows the gas outside the heating element 10 to flow to the end of the aerosol product 200 through the inlet and outlet 112 and the guide grooves 115 in sequence. In a specific implementation, when the airflow passes through the guide grooves 115, the heating element base 11 can heat the airflow, so that the temperature of the gas flowing to the end of the aerosol product 200 is higher than the temperature of the gas outside the heating element.
[0048] See also Figure 3 and Figure 4A stopper 116 is provided on the side of the bottom wall 114 facing the accommodating cavity 111. That is, the stopper 116 is provided on the inner side of the bottom wall 114. The stopper 116 is used to abut the end of the aerosol product 200, so that a gap 13 is formed 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 115 away from the inlet and outlet 112 is connected to the gap 13. The guide groove 115 can guide the airflow from the inlet and outlet 112 to the gap 13. With this arrangement, the inlet and outlet 112, the guide groove 115, and the gap 13 form an airflow channel. The airflow can flow from the outside of the heating element 10 through the inlet and outlet 112 and the guide groove 115 in sequence to the gap 13, and then enter the aerosol product 200 from the end through the gap 13.
[0049] In specific implementation, when the airflow passes through the guide groove 115 and the gap 13, the heating body base 11 can heat the airflow passing through, heating the cold airflow into a hot airflow, that is, the airflow entering the aerosol product 200 is a hot airflow, thereby heating the aerosol product 200.
[0050] The diameter of the main body 113 matches the diameter of the aerosol product 200, so that when the aerosol product 200 is placed in the accommodating chamber 111, the inner side of the main body 113 contacts the outer periphery of the aerosol product 200. In this way, the main body 113 can not only heat the airflow flowing through the guide groove 115, but also directly heat the outer periphery of the aerosol product 200 through contact with the aerosol product 200, thereby improving the heating efficiency of the aerosol product 200.
[0051] In one embodiment, a plurality of guide grooves 115 are provided on the inner side of the main body 113, and the plurality of guide grooves 115 are arranged at equal intervals along the circumference of the main body 113, so that the airflow flowing from the guide grooves 115 to the gap 13 is evenly distributed along the circumference of the aerosol product 200 and can be evenly heated, and also enables the main body 113 to evenly directly heat the circumference of the aerosol product 200.
[0052] See also Figures 2 to 4The heating element base 11 further includes a connecting portion 117, which is provided at the first end of the main body 113 and is used to connect to the fixing assembly 20 of the atomizing device 103. Since the bottom wall 114 is connected to the second end of the main body 113, the heating circuit 12 is provided on the bottom wall 114, so that the heating circuit 12 is located at the second end of the main body 113, and the connecting portion 117 is provided at the first end of the main body 113. Therefore, a greater distance can be created between the heating circuit 12 and the connecting portion 117. The greater distance between the heating circuit 12 and the fixing assembly 20 allows most of the heat generated by the heating circuit 12 to be transferred to the corresponding accommodating cavity 111 during the process of being transferred to the fixing assembly 20, and then used to heat the aerosol product 200. In this way, the heat absorbed by the fixing assembly 20 is reduced, further reducing heat energy loss.
[0053] In one embodiment, the connection portion 117 includes a flange 1171 disposed around the circumference of the main body 113. In a specific implementation, the flange 1171 is connected to the fixing assembly 20, so that the heating element 10 is connected to the fixing assembly 20.
[0054] See also Figure 3 and Figure 4 The fixing assembly 20 includes a first sleeve 21 and a second sleeve 22. The first sleeve 21 includes a coaxially arranged first barrel 211 and a first inner shrinkage tube 212, and the first inner shrinkage tube 212 shrinks inward from one end or the interior of the first barrel 211. The second sleeve 22 includes a coaxially arranged second barrel 221 and a second inner shrinkage tube 222, and the second inner shrinkage tube 222 shrinks inward from one end or the interior of the second barrel 221. The first barrel 211 is connected to one end of the second barrel 221, and the first inner shrinkage tube 212 extends into the second barrel 221 and extends in a direction close to the second inner shrinkage tube 222. The heating element 10 is connected between the first inner shrinkage tube 212 and the second inner shrinkage tube 222 and is suspended in the second sleeve 22. In a specific implementation, the connecting portion 117 is connected between the first inner shrinkage tube 212 and the second inner shrinkage tube 222. By connecting the connecting portion 117 to the fixing assembly 20, the heating element 10 is suspended, which is conducive to reducing heat energy loss.
[0055] In this embodiment, the connecting portion 117 is configured as a flange 1171, which is supported on the second inner shrinkage tube 222. The first inner shrinkage tube 212 is located above the flange 1171, that is, the flange 1171 is clamped between the first inner shrinkage tube 212 and the second inner shrinkage tube 222. Such a configuration can improve the firmness of the connection between the heating element 10 and the fixing component 20.
[0056] See also Figure 2 and Figure 3The 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 further reduce heat energy loss.
[0057] 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. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
