Description

Technical Field

[0002] like Figure 1 As shown, in a conventional heat-not-burn smoking device, a heating component 01 on a heating needle 00 is attached to the surface of the heating needle 00 and connected to a circuit board through a lead 02. The heating needle 00 is welded to the lead 02, and a solder joint 03 between the two is located at the lower end of the base 04 of the heating needle 00, that is, the heating component 01 on the heating needle 00 passes through the base 04 and is welded to the lead 02 below the base 04. When the heating component 01 is working, most of the area of ​​the heating component 01 is located above the base, which can generate a large amount of heat, forming a high-temperature area 05, and atomizing the tobacco product to form aerosol. The part of the heating component 01 located inside and below the base 04 also generates heat due to the flow of current, but when the heating needle 00 is inserted into the tobacco product, the tobacco product can only contact the heating component located above the base, but not the heating component located inside and below the base 04, so that the heat generated by this part is wasted, resulting in low power utilization. In addition, it is not easy to install the heating needle 00 by setting the welding point 03 of the heating component 01 and the lead 02 at the lower end of the base 04 of the heating needle 00. The shape of the welding point 03 is irregular, and it is difficult to form a good match and positioning with the installation component of the heating needle 00.

[0027] like Figures 2 to 5 As shown, the present invention discloses an atomization assembly 1, comprising: a base 10, which includes a base body 100, which is used to be installed in an aerosol generating device; a base body 11, which is arranged on the base body 100, and an atomization part 110 is arranged on the base body 11, which is used to atomize the aerosol generating matrix; an electrical connection end 120, which is used to connect the atomization part 110 with the electrical connection lead 12, wherein in the extension direction of the base body 11 (such as Figure 2In the figure (shown in the direction B), the atomization portion 110 and the electrical connection end 120 are located on the same side of the base body 100.

[0028] That is, the atomizing assembly 1 is mainly composed of a base 10, a substrate 11 and an electrical lead 12, wherein the substrate 11 is disposed on a seat 100 of the base 10, an atomizing portion 110 is disposed on the substrate 11, and the atomizing portion 110 is electrically connected to the electrical lead 12. For details, see Figure 2 As shown, in the present embodiment, in the extension direction of the base 11, the atomizing part 110 and the electrical connection end 120 are located on the same side of the base 100, that is, in the extension direction of the base 11, the atomizing part 110 and the base 100 are arranged at a certain distance, and can be connected to the electrical lead 12 without passing through the base 100, that is, the atomizing part 110 and the electrical connection end 120 are both located above the base 10, and the heat generated by the atomizing part 110 can atomize the aerosol to generate the matrix, and no heat will be generated around the base 10 due to the power supply, so that the heating zone of the atomizing part 110 only exists above the base 10, thereby avoiding the loss of electric power of the atomizing part 110 and improving the power utilization rate of the atomizing part 110.

[0029] By adopting the above technical solution, the base and the atomization part are spaced apart, and the atomization part and the electrical leads are all located above the base. There is no need to pass through the base, and no heating area is formed around the base, which avoids the loss of electric power in the atomization part and improves the power utilization of the atomization part.

[0030] Further, see Figure 2 As shown, in this embodiment, the electric lead 12 passes through the base body 100 of the base 10 along the extension direction of the base 11, and is electrically connected to the atomizing part 110 disposed on the base 11. That is, the atomizing part 110 can be electrically connected to the electric lead 12 to form an electrical connection end 120 without passing through the base body 100 of the base 10. The electrical connection end 120 and the atomizing part 110 are located on the same side of the base 10, and are all located above the base body 100. No heating zone is formed around the base 10, which avoids the loss of electric power of the atomizing part 110, improves the power utilization of the atomizing part, and can more efficiently atomize the aerosol-generating substrate.

[0031] In other embodiments, the electrical leads may not pass through the seat body. For example, after the electrical leads are electrically connected to the atomization part, the electrical leads may be arranged along the surface of the substrate or the upper surface of the base and extended radially outward from the substrate. The present invention is not limited to this and may be reasonably arranged according to the specific structure, as long as the electrical leads can effectively realize the electrical connection between the atomization part and the circuit board.

[0032] For details, see Figure 4 and Figure 5 Combined with Figure 2 and Figure 3 As shown, in this embodiment, the base 10 includes a base body 100 , on which a channel 103 is provided. The electrical lead 12 can extend from the channel 103 through the base body 100 to a certain height and then be electrically connected to the atomization part 110 through the electrical connection end 120 .

[0033] That is, a channel 103 is provided on the base body 100, one end of the electric lead 12 is electrically connected to the circuit board (not shown in the figure), and the other end of the electric lead 12 can pass upward through the channel 103 on the base body 100 and be electrically connected to the atomization part 110 through the electrical connection end 120. Preferably, the electric lead 12 is electrically connected to the atomization part 110 after passing through the base body 100 to a certain height, wherein the certain height refers to the height of the electrical connection end 120 of the electric lead 12 and the atomization part 110 from the base body 100, and the specific value can be selected according to actual conditions, as long as the electrical connection end and the atomization part can be all located above the base. By setting a channel 103 on the base 10, it is convenient for the electric lead 12 to pass through and be arranged from the base 10. By limiting the height of the electrical connection end between the electric lead 12 and the atomization part 110 from the base body 100, the electrical connection end and the atomization part can all be located above the base, ensuring that the heating zone of the atomization part 110 is formed above the base 10 of the substrate 11, avoiding the loss of electric power in the atomization part 110, and improving the power utilization rate of the atomization part.

[0034] In other embodiments, the electrical leads and the seat body may also be connected in other ways. For example, the electrical leads may be embedded in the seat body during the seat body processing so that the electrical leads are fixedly connected to the seat body. The present invention does not limit this and can be reasonably configured according to actual needs.

[0035] Further, see Figure 4 As shown, in this embodiment, a recess 104 is provided on the seat body 100, and the electrical lead 12 can enter the recess 104 through the channel 103 to be electrically connected to the atomization part 110 through the electrical connection end 120, and the electrical connection end 120 is formed in the recess 104, or, the electrical lead 12 can pass through the recess 104 through the channel 103 and then be electrically connected to the atomization part 110 through the electrical connection end 120, and the electrical connection end 120 is formed on the upper side of the recess 104.

[0036] That is, the electric lead 12 can enter the recess 104 or pass through the recess 104 through the channel 103. When the electric lead 12 enters the recess 104 through the channel 103, the electric lead 12 can be electrically connected to the atomization part 110 in the recess 104, and an electrical connection end 120 is formed in the recess 104. The provision of the recess 104 can increase the area of ​​the electrical connection end 120 formed by the electrical connection between the electric lead 12 and the atomization part 110, so that a stable welding point can be formed between the electric lead 12 and the atomization part 110 during the welding process, ensuring a stable and reliable connection between the electric lead 12 and the atomization part 110. When the electric lead 12 passes through the concave portion 104 through the channel 103, the electric lead 12 can be electrically connected to the atomizing portion 110 above the concave portion 104, and the square electrical connection end 120 is formed on the upper side of the concave portion 104. The provision of the concave portion 104 can also increase the area of ​​the electrical connection end 120 formed by the electrical connection between the electric lead 12 and the atomizing portion 110, so that a stable welding point can be formed between the electric lead 12 and the atomizing portion 110 during the welding process, ensuring a stable and reliable connection between the electric lead 12 and the atomizing portion 110. Among them, the concave portion 104 can be a groove that opens toward the inside and the top of the seat body 100, or it can be an open cavity. The present invention does not limit this, and a reasonable selection can be made according to actual needs, as long as the area of ​​the electrical connection end formed by the electrical lead and the atomizing portion can be increased.

[0037] Further, see Figure 4 and Figure 5 Combined with Figure 2 and Figure 3 As shown, in this embodiment, the base 10 further includes a bracket 13, the base body 100 is arranged on the bracket 13, and the electrical connection end 120 is clamped by the base body 100 and the bracket 13. That is, by arranging the base body 100 on the bracket 13, a complete base 10 is formed, and the bracket 13 has a clamping effect on the welding point of the electrical connection end 120 formed in the recess 104, on the one hand, it stabilizes the connection between the electric lead 12 and the atomization part 110, and on the other hand, it is convenient for the installation of the base 10. A channel 103 is also provided on the bracket 13, and the electric lead 12 can be at least partially located in the channel 103 on the bracket 13. When the base body 100 is installed in the bracket 13, the bracket 13 can compress the electrical connection end 120 between the electric lead 12 and the atomization part 110, and limit the electrical connection end 120 between the electric lead 12 and the atomization part 110, so as to ensure that the electric lead 12 and the atomization part 110 can be stably and reliably connected. The seat body 100 can be arranged inside the bracket 13, or can be connected to the bracket 13 outside the bracket 13. The present invention does not limit this and can be reasonably arranged according to actual needs, as long as the seat body can be stably and reliably arranged on the bracket and the bracket can define the electrical connection end between the electrical lead and the atomization part.

In other embodiments, the bracket can also be a whole, that is, the bracket can also be formed by one-piece molding. The present invention does not limit the specific structure, number and connection method of the bracket unit, and can be reasonably selected according to actual needs, as long as the various bracket units can be combined into a complete bracket.

The first bracket 130 is sleeved on the base 11 from the upper end of the base 11, and the second bracket 131 is fitted with the first bracket 130 from the lower end or below the base 11, so that the seat 100 is located in the space formed by the connection of the first bracket 130 and the second bracket 130, that is, in the extension direction of the base 11, the first bracket 130 and the second bracket 131 are adjacently fitted to form a complete bracket 13, so that the seat 100 and the base 11 are stably and reliably installed on the bracket 13.

[0043] In addition, the base body 100, the first bracket 130 and the second bracket 131 are all provided with channels 103 for the power lead 12 to pass through. The number of channels 103 can be set according to the number of the power leads 12, for example, two, three or four channels can be set, and the size and shape of the channels 103 can be set according to the size and shape of the power leads 12, for example, they can be set as through holes, semicircular holes, arc holes or stepped holes, etc., to facilitate the passage of the power leads 12.
