[0028] Please refer to Figure 1 The present application provides an atomizing device 1, which can be used for atomizing an aerosol-generating substrate. Specifically, the atomizing device 1 includes a power supply component 2 and an atomizer 3. The atomizer 3 can be the atomizer 3 involved in any of the embodiments below. The atomizer 3 can be used in different fields, such as the electronic cigarette field, the medical atomization field, etc. The atomizer 3 is used to store the aerosol-generating substrate, and heat and atomize the aerosol-generating substrate to generate an aerosol. The aerosol-generating substrate can be, for example, a liquid substrate such as tobacco oil and liquid medicine.

[0029] The power supply assembly 2 is electrically connected to the atomizer 3. Specifically, the power supply assembly 2 and the atomizer 3 may be detachably connected, and the detachable connection between the power supply assembly 2 and the atomizer 3 may be, for example, a snap connection, a magnetic connection, or an interference fit connection, or one of the power supply assembly 2 and the atomizer 3 may have a cavity 513, and the other may be inserted into the cavity 513 to achieve detachable connection. In some embodiments, the power supply assembly 2 and the atomizer 3 may also be non-detachably connected.

[0030] Generally, the power supply assembly 2 may include a battery and a controller. The battery is used to supply power to the atomizer 3. After receiving the start signal, the controller can control the battery to supply power to the atomizer 3, and can control the power, duration, mode, etc. of the atomizer 3 when heating.

[0031] The present application provides an atomizer 3, which can be applied to an atomizer device 1. The atomizer 3 includes a heating element 5. The heating element 5 can be the heating element 5 involved in any of the embodiments below. The atomizer device 1 has an air inlet channel and an air outlet channel, and the interior of the heating element 5 has an atomization channel 61, one end of the atomization channel 61 is connected to the air inlet channel, and the other end of the atomization channel 61 is connected to the air outlet channel. During inhalation, the airflow enters the atomizer device 1 from the air inlet channel, flows from the air inlet channel to the atomization channel 61, and flows out from the air outlet channel after carrying the aerosol atomized in the atomization channel 61.

[0032] like Figure 2 As shown, the heating element 5 also includes a liquid guiding element 6 and a heating portion 51. In one embodiment, the interior of the liquid guiding element 6 has an atomization channel 61 that runs through the liquid guiding element 6. In one embodiment, the atomization channel 61 is cylindrical, and both ends of the atomization channel 61 are open ends, one open end of the atomization channel 61 is connected to the air inlet channel, and the other open end of the atomization channel 61 is connected to the air outlet channel. The heating portion 51 is arranged inside the atomization channel 61, and the outer side surface of the heating portion 51 is arranged in contact with the inner side surface of the atomization channel 61, so that the liquid guiding element 6 can guide the aerosol-generating matrix to the heating portion 51. The material of the liquid guiding element 6 has a porous structure, for example, it can be cotton, ceramic, etc.

[0033] exist Figure 2 In the example shown, the liquid guiding member 6 is sleeved on the outside of the heating portion 51. In other embodiments, the heating portion 51 can also be sleeved on the outside of the liquid guiding member 6, that is, the liquid guiding member 6 is arranged inside the heating portion 51, and the inner side surface of the heating portion 51 is arranged in contact with the outer side surface of the liquid guiding member 6. In other embodiments, at least part of the heating portion 51 can also be embedded in the liquid guiding member 6. In the present application, since the heating member 5 can be wound into a full circle structure, when it is arranged on the inner or outer side of the liquid guiding member 6, it can be well fitted on the inner surface or outer surface of the liquid guiding member 6, and play a certain supporting and fixing role for the liquid guiding member 6.

[0034] Please refer to Figure 3-6 The present application provides a heating element 5, which further includes a first electrode portion 52, a second electrode portion 53, a first insulating portion 54 and a second insulating portion 55. The heating portion 51 is generally cylindrical in structure (since the first end 511 and the second end 512 of the heating portion 51 cannot contact each other, the heating portion 51 does not form a complete cylindrical shape). Along the circumferential direction of the heating portion 51, the heating portion 51 has a first end 511 and a second end 512 that are relatively close to each other, that is, the first end 511 and the second end 512 are located on both sides of the heating portion 51, and the first end 511 and the second end 512 can be used as pins of the heating portion 51 for electrical connection with the power supply component 2.

[0035] In one embodiment, the heating portion 51 may be a mesh structure. The material of the heating portion 51 may be iron-chromium-aluminum or nickel-chromium or stainless steel.

[0036] The first electrode portion 52 is electrically connected to the first end 511 of the heating portion 51, and the second electrode portion 53 is electrically connected to the second end 512 of the heating portion 51. Both the first electrode portion 52 and the second electrode portion 53 are used to be electrically connected to the battery so that the battery can supply power to the heating portion 51. The first electrode portion 52 is fixedly connected to the first end 511 of the heating portion 51, which can be welded, such as laser spot welding, or fixedly connected by other means such as screws, nails, copper pillars, etc.; the second electrode portion 53 is fixedly connected to the second end 512 of the heating portion 51, which can be welded, such as laser spot welding, or fixedly connected by other means such as screws, nails, copper pillars, etc.

[0037] The first insulating portion 54 is disposed on the first electrode portion 52 and the first end 511, and the second insulating portion 55 is disposed on the second electrode portion 53 and the second end 512. The first end 511 and the second end 512 are separated by the first insulating portion 54 and the second insulating portion 55, and the first electrode portion 52 and the second electrode portion 53 are separated by the first insulating portion 54 and the second insulating portion 55. The side surface of the first end 511 and the side surface of the upper end of the first electrode portion 52 are completely wrapped by the first insulating portion 54, and the side surface of the second end 512 and the side surface of the upper end of the second electrode portion 53 are completely wrapped by the second insulating portion 55. The upper end of the first electrode portion 52 is the portion connected to the first end 511, and the upper end of the second electrode portion 53 is the portion connected to the second end 512. The first insulating portion 54 and the second insulating portion 55 are insulating materials, such as ceramic materials. Preferably, the first insulating portion 54 and the second insulating portion 55 can be made of hard insulating materials so that the first insulating portion 54 and the second insulating portion 55 can provide hard support.

[0038] The heating part 51, the first insulating part 54 and the second insulating part 55 are wound and enclosed to form a cylindrical tube structure, and the first insulating part 54 and the second insulating part 55 are in contact with each other. The projection of the heating element 5 on the projection plane is a full circle, and the projection plane is perpendicular to the axis of the heating element 5. The projection of the heating element 5 on the projection plane is a full circle, which means that the outer contour of the projection of the heating element 5 on the projection plane is a full circle, and / or the inner contour of the projection of the heating element 5 on the projection plane is a full circle. That is, from Figure 3The heating part 51, the first insulating part 54 and the second insulating part 55 are observed from a top view. The heating part 51, the first insulating part 54 and the second insulating part 55 can form a whole circle, so that when the entire heating element 5 is viewed from a top view, the outer contour and / or inner contour of the cross-section of the heating element 5 is a whole circle, wherein the first insulating part 54 and the second insulating part 55 can be abutted to form a whole circle, and the first insulating part 54 and the second insulating part 55 can also have a slight gap, which can be at the centimeter level or the millimeter level depending on the process level.

[0039] The heating element 5 of the present application is provided with a first insulating portion 54 and a second insulating portion 55. On the one hand, compared with the existing heating network, a large gap must be left at both ends of the existing heating network to prevent short circuit, while the heating element 5 of the present application can be enclosed into a complete cylindrical structure by the first insulating portion 54 and the second insulating portion 55. The entire heating element 5 can be wound into a full circle structure from a top view. The complete cylindrical structure can improve the structural strength of the heating element 5, and the first insulating portion 54 and the second insulating portion 55 can separate the two ends of the heating part 51, and will not cause the heating part 51 to short-circuit; on the other hand, the first insulating portion 54 and the second insulating portion 55 can provide hard support, so that the heating element 5 has a hard support structure when installed on the liquid guide 6, and the heating element 5 is not easy to deform during suction, thereby improving the life of the heating element 5. In addition, the present application forms a cylindrical cylindrical structure by winding the heating element 5, and the cylindrical heating element 5 can match the cylindrical atomization channel 61, which is easier to assemble the heating element 5 and the liquid guide 6.

[0040] In one embodiment, if Figure 6As shown, the first electrode portion 52 includes a first contact segment 521, and the second electrode portion 53 includes a second contact segment 531. The first contact segment 521 abuts against the first end 511 of the heating portion 51, and the second contact segment 531 abuts against the second end 512 of the heating portion 51. In one embodiment, the first contact segment 521 is welded to the first end 511 of the heating portion 51, and the second contact segment 531 is welded to the second end 512 of the heating portion 51. The first insulating portion 54 wraps the first end 511 and the first contact segment 521, so that the connection position between the first contact segment 521 and the first end 511 is located inside the first insulating portion 54, and the second insulating portion 55 wraps the second end 512 and the second contact segment 531, so that the connection position between the second contact segment 531 and the second end 512 is located inside the second insulating portion 55. Since the temperature at the connection point is relatively high, if the connection point is exposed to the outside, the liquid-conducting member 6 in contact with the heating member 5 may easily turn yellow or black, which may further cause the aerosol-generating matrix to change color. However, the present application uses an insulating portion (a first insulating portion 54 and a second insulating portion 55) to wrap the ends (the first end 511 and the second end 512) of the heating portion 51 and the connection between the electrode portion (the first electrode portion 52 and the second electrode portion 53), so that the connection point between the heating portion 51 and the electrode portion can be hidden inside the insulating portion, thereby preventing the connection point between the heating portion 51 and the electrode portion from being directly exposed, which is beneficial to preventing the aerosol-generating matrix and the liquid-conducting member 6 from changing color.

[0041] In one embodiment, if Figure 4 and Figure 7 As shown, a cavity 513 is provided in the cylindrical structure of the heating part 51. The outer side surface of the first insulating part 54 away from the cavity 513 is an arc surface, and the outer side surface of the second insulating part 55 away from the cavity 513 is an arc surface. In this embodiment, the outer side surface of the first insulating part 54 away from the cavity 513 and the outer side surface of the second insulating part 55 away from the cavity 513 are both used to fit the inner side surface of the liquid guide channel. By setting the outer side surface of the first insulating part 54 and the outer side surface of the second insulating part 55 as an arc surface, the arc surface can be enclosed with the heating part 51 to form the entire side surface of the cylinder, thereby improving the structural strength of the heating element 5.

[0042] In one embodiment, the inner side surface of the first insulating portion 54 close to the cavity 513 is an arc surface, and the inner side surface of the second insulating portion 55 close to the cavity 513 is an arc surface. In this embodiment, the inner side surface of the first insulating portion 54 close to the cavity 513 and the inner side surface of the second insulating portion 55 close to the cavity 513 are both used to fit the outer side surface of the liquid guide 6. Similarly, the arc surface can be enclosed with the heating portion 51 to form the entire side surface of the cylinder, thereby improving the structural strength of the heating element 5.

[0043] Specifically, Figure 4 and Figure 7As shown, the first contact segment 521 and the second contact segment 531 are arranged inside the cavity 513, and the outer side surface of the heat generating portion 51 away from the cavity 513, the outer side surface of the first insulating portion 54 away from the cavity 513, and the outer side surface of the second insulating portion 55 away from the cavity 513 form a cylindrical structure, that is, the outer side surface of the heat generating portion 51 away from the cavity 513, the outer side surface of the first insulating portion 54 away from the cavity 513, and the outer side surface of the second insulating portion 55 away from the cavity 513 form the entire side surface of the cylinder, and the projection on the projection plane is a whole circle. Alternatively, the first contact segment 521 and the second contact segment 531 are arranged outside the cavity 513, and the inner side surface of the heat generating portion 51 close to the cavity 513, the inner side surface of the first insulating portion 54 close to the cavity 513, and the inner side surface of the second insulating portion 55 close to the cavity 513 form a cylindrical structure, that is, the inner side surface of the heat generating portion 51 close to the cavity 513, the inner side surface of the first insulating portion 54 close to the cavity 513, and the inner side surface of the second insulating portion 55 close to the cavity 513 form the entire side surface of the cylinder, and the projection on the projection plane is a whole circle.

[0044] In one embodiment, if Figure 6 As shown, the first electrode portion 52 further includes a first extension segment 522, and the second electrode portion 53 further includes a second extension segment 532. The first extension segment 522 is electrically connected to the first contact segment 521, and the second extension segment 532 is electrically connected to the second contact segment 531. The first extension segment 522 and the second extension segment 532 are used to be electrically connected to the power supply component 2. The first extension segment 522 and the second extension segment 532 are generally linear structures, so as to facilitate the electrical connection of the heating portion 51 to the power supply component 2 which is far away.

[0045] In one embodiment, if Figure 6As shown, the first extension section 522 includes a first protective member 5221 and a first wire 5222, and the second extension section 532 includes a second protective member 5321 and a second wire 5322. The first wire 5222 is electrically connected to the first contact section 521, and the second wire 5322 is electrically connected to the second contact section 531. The first wire 5222 and the first contact section 521 can be two regions of the same metal pin / wire, or can be fixedly connected as one by two metal pins / wires, and the second wire 5322 and the second contact section 531 can be two regions of the same metal pin / wire, or can be fixedly connected as one by two metal pins / wires; the first protective member 5221 and the second protective member 5321 are configured as insulators, the first protective member 5221 is sleeved on the outside of the first wire 5222, and the second protective member 5321 is sleeved on the outside of the second wire 5322. By providing the first protective member 5221 and the second protective member 5321 , on the one hand, the first wire 5222 and the second wire 5322 can be prevented from short-circuiting due to contact; on the other hand, in the atomization device 1 , the aerosol-generating matrix may flow onto the electrode, and the protective member can protect the first wire 5222 and the second wire 5322 .

[0046] In one embodiment, the first extension section 522 and the second extension section 532 are both configured as OK wires, which are also called circuit board flying wires or circuit board jumpers, and are leads with soft insulating skin wrapped on the outside. By configuring the first extension section 522 and the second extension section 532 as OK wires, the OK wires are smaller in size, and the extension section wiring can be prevented from occupying too much volume of the atomizing device 1. In addition, the OK wires are relatively soft and can be bent and deformed, so that the layout of the atomizing device 1 can be adapted to more scenarios when routing, and are more versatile.

[0047] Please refer to Figure 8 When manufacturing the heating element 5 provided in an embodiment of the present application, a clamp 7 can be used to assist the heating element 5 in winding into a full circle structure. The side wall of the heating part of the clamp 7 used to support the heating element 5 is an arc surface. The clamp 7 is provided with an air avoidance groove 71. The air avoidance groove 71 is used to avoid the first electrode part 52, the second electrode part 53, the first insulating part 54 and the second insulating part 55 of the heating element 5, that is, the first electrode part 52, the second electrode part 53, the first insulating part 54 and the second insulating part 55 are arranged in the air avoidance groove 71. After the heating element 5 is wound into a full circle structure, liquid-conducting cotton can be wound on the outer side of the heating element 5 with the assistance of the clamp 7. The clamp 7 can prevent the deformation of the heating element 5 during the winding process. Finally, the clamp 7 is pulled out to manufacture the heating element 5 of the present application.

[0048] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application.
