Referring to FIG. 1 to FIG. 4, an atomization device 100, according to an embodiment of the present application, includes a heating body 10 and a heating element 20. The heating body 10 includes a liquid absorbing surface 11 and an atomizing surface 12 opposite the liquid absorbing surface 11. The heating body 10 defines a flow channel 13 passing through the liquid absorbing surface 11 and the atomizing surface 12. The heating element 20 is at least partially located on one side of the liquid absorbing surface 11. The maximum height of the heating element 20 from the liquid absorbing surface 11 is greater than 0.5mm.

In the atomization device 100, according to the embodiment of the present application, the maximum height of the heating element 20 from the liquid absorbing surface 11 of the heating body 10 is greater than 0.5mm, so that the heating element 20 can heat the aerosol precursor which distance from the liquid absorbing surface 11 is greater than 0.5mm, so as to reduce the viscosity of the aerosol precursor. The aerosol precursor can flow through the flow channel 13, and the probability of dry burning of the heating body 10 is reduced.

In particular, the atomization device 100 is a component which can atomize the aerosol precursor into aerosol. The atomization device 100 can atomize the aerosol precursor into aerosol by heating. The heating body 10 is a component configured to generate heat. The liquid absorbing surface 11 of the heating body 10 is the first contact surface with the aerosol precursor. The atomizing surface 12 of the heating body 10 is the surface on which the aerosol precursor is atomized to form an aerosol. The flow channel 13, such as a circular hole, can guide the aerosol precursor from the liquid absorbing surface 11 to the atomizing surface 12.

As discussed above, the heating body 10 can generate heat by itself, thus the aerosol precursor around the atomizing surface 12 of the heating body 10 is heated and atomized. However, the area of the aerosol precursor heated by the heating body 10 is small, so that the amount of the aerosol precursor heated by the heating body 10 is small, which may be difficult to meet the requirements. Thus, the heating element 20 is at least partially disposed on one side of the liquid absorbing surface 11, and the maximum height H of the heating element 20 from the liquid absorbing surface 11 is greater than 0.5mm, so that the heating element 20 can exchange heat with more aerosol precursor around. The temperature of the aerosol precursor around the heating element 20 can be increased, and the viscosity of the aerosol precursor around the heating element 20 can be decreased. The fluidity of the aerosol precursor is enhanced, which makes it easier for the aerosol precursor to reach the atomizing surface 12 through the flow channel 13, and reduces the probability of dry burning of the heating body 10.

It should be noted that the maximum height H of the heating element 20 from the liquid absorbing surface 11 refers to the maximum size between the heating element 20 and the liquid absorbing surface 11, along the normal direction of the liquid absorbing surface 11.

The aerosol precursor in some embodiments of this application can be the high viscosity aerosol precursor. The viscosity of the aerosol precursor can be greater than 10000cps at room temperature (25℃) . In some embodiments of this application, the viscosity of the aerosol precursor can be measured by the GBT 17473.5-1998 test methods of precious metal pastes used for thick film microelectronics.

In some embodiments, the maximum height H of the heating element 20 from the liquid absorbing surface 11 can be 0.6mm, 1mm, 1.5mm, 2mm, 3mm or other sizes.

Referring to FIG. 5 and FIG. 6, in some embodiments, the heating body 10 can include a substrate 14 and a heating film 15 mounted on the substrate 14. The substrate 14 includes the liquid absorbing surface 11. The heating film 15 includes the atomizing surface 12. The substrate 14 can be sheet-shaped and can be made of glass, dense ceramic and other materials. The heating film 15 can be made of metal, alloy and other conductive and easy to generate heat materials. For example, the material of the heating film 15 can be gold, silver, platinum, palladium, palladium copper alloy, gold and silver platinum alloy, gold and silver alloy, titanium zirconium alloy, palladium silver alloy, gold and platinum alloy, or stainless steel, etc.

In some embodiments, the heating element 20 is a metal heating element 20. Alternatively, the heating element 20 can be made of metal material. Therefore, the metal heating element 20 has good thermal conductivity and can quickly exchange heat with the aerosol precursor, thus heating the aerosol precursor. In an example, the heating element 20 can raise the temperature of the surrounding aerosol precursor by more than 10℃.

In some embodiments, the heating element 20 is stainless steel heating element 20 or aluminum heating element 20. Alternatively, the heating element 20 can be made of stainless steel or aluminum. Stainless steel or aluminum has good thermal conductivity and is easy to form, so that the heating elements 20 can be manufactured more easily.

In some embodiments, the heating element 20 can be made of copper, or metal alloys, etc.

In some embodiments, the heating element 20 is formed by a die casting process and/or a stamping process. Therefore, the heating element 20 easily forms a predetermined shape, thereby heating the aerosol precursor. For example, in the embodiment shown in FIG. 7 to FIG. 9, the heating element 20 can be molded by a die casting process. In the embodiment of FIG. 12, the heating element 20 can be formed by a die casting process.

Referring to FIG. 4, in some embodiments, the maximum height of the heating element 20 from the liquid absorbing surface 11 is ranged from 1mm to 3mm. For example, the maximum height H can be 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.5mm, 3mm and so on. In the case of the maximum height H within this range, a sufficient amount of the aerosol precursor can be heated. Alternatively, a sufficient amount of the aerosol precursor can be atomized through the flow channel 13, and the volume of the heating element 20 can be reduced. The atomization device 100 can be more miniaturized.

Referring to FIG. 4, in some embodiments, the heating element 20 includes a base 21 and an extending portion 22. The base 21 is arranged near the heating body 10. The extending portion 22 extends from the base 21 to a direction opposite the heating body 10. The maximum height H of the extending portion 22 from the liquid absorbing surface 11 is greater than 0.5mm.

Thus, the base 21 can make the heating element 20 more stable during installation. The extending portion 22 can increase the height of the heating element 20 and heat the aerosol precursor, thereby expanding the heating range of the heating element 20, and the maximum height H of the heating element 20 from the liquid absorbing surface 11 of the heating element 20 can meet the requirement of greater than 0.5mm.

In particular, the base 21 and the extending portion 22 can both be sheet-shaped. The outline of the base 21 can be square, and the extending portion 22 can be strip-shaped. The maximum height H of the extending portion 22 from the liquid absorbing surface 11 is the maximum height H of the heating element 20 from the liquid absorbing surface 11.

Referring to FIG. 4 and FIG. 7, in some embodiments, the base 21 defines a through hole 211. The through hole 211 penetrates two surfaces in a direction of the thickness of the base 21. Thus, the through hole 211 can reduce the flow resistance of the aerosol precursor, so that the heated aerosol precursor can flow more easily to the liquid absorbing surface 11, and the aerosol precursor can be atomized on the atomizing surface 12 after passing through the flow channel 13.

In particular, the through hole 211 can be a square hole, a round hole, etc. The projection of the through-hole 211 on the liquid absorbing surface 11 can coincide with at least part of the region of the flow channel 13, thus the aerosol precursor can flow faster to the liquid absorbing surface 11 after passing through the through-hole 211.

Referring to FIG. 7, in some embodiments, the extending portion 22 includes at least one fin 221. The edge near the through hole 211 of each of the fin 221 is connected to the base 21. Thus, the surface of the fin 221 is large, which can increase the heating efficiency of the heating element 20, and reduce the viscosity of the aerosol precursor more quickly. In addition, due to the fin 221 is close to the edge of the through hole 211, the temperature of the aerosol precursor flowing through the through hole 211 will not be reduced. The aerosol precursor can maintain a lower viscosity, and the aerosol precursor can flow more smoothly to the atomizing surface 12. Thus, the probability of dry burning of the heating body 10 can be reduced.

In particular, the fin 221 can be strip-shaped, bent-shaped, or frame-shaped. This application does not restrict the specific shape and the structure of the fin 221, as long as the fin 221 can heat the aerosol precursor.

Referring to FIG. 7 and FIG. 8, in some embodiments, the base 21 defines a plurality of through holes 211. The edge of each of the through holes 211 is connected with the fin 221. Thus, the extending portion 22 includes a plurality of fins 221, thereby the heating area of the heating element 20 is larger, which is conducive to improving the heating efficiency of the heating element 20 on the aerosol precursor. In addition, the fins 221 can heat the aerosol precursor flowing through each of the through-holes 211, thereby reducing the viscosity of the aerosol precursor and increasing the overall fluidity of the aerosol precursor.

In the case that the extending portion 22 includes a plurality of fins 221, the type of the fins 221 can be the same or different. As shown in FIG. 7, part of the fins 221 is strip-shaped, and part of the fins 221 is bent-shaped. As shown in FIG. 8, FIG. 9, and FIG. 12, the fins 221 have the same construction.

In particular, the number of the through hole 211 can be two, three, four and so on. In the example shown in FIG. 9, the number of the through holes 211 is two. In the example shown in FIG. 10, the number of the through holes 211 is three. The edge of the through hole 211 can connect to one or more fins 221. For example, in the example shown in FIG. 9, the edge of the through-hole 211 connects to a fin 221. In the example shown in FIG. 11, the edge of one of the through-holes 211 connects two fins 221.

Furthermore, the number of the fins 221 connected at the edges of each through-hole 211 can be the same or different. In the example shown in FIG. 11, the edge of the middle through hole 211 is connected with two fins 221, and the edge of the side through hole 211 is connected with one fin 221.

Referring to FIG. 12, in some embodiments, the extending direction of the fin 221 is substantially parallel to the thickness direction of base 21. Thus, each side of the fin 221 can be in contact with the aerosol precursor to heat the aerosol precursor. The aerosol precursor can flow along the side of the fin 221 to the base 21, so that the flow resistance of the aerosol precursor is small, which is conducive to the flow of the aerosol precursor. In addition, the fin 221 can form a larger maximum height H, which increases the heating range of the heating element 20. The viscosity of more aerosol precursor can be reduced.

Referring to FIG. 13, in some embodiments, the extending direction of the fin 221 is substantially inclined to the thickness direction of the base 21. Thus, the fin 221 can reduce the flow speed of the aerosol precursor. The contact time between the fin 221 and the aerosol precursor is longer, which is conducive to heating the aerosol precursor, so that the viscosity of the aerosol precursor flowing to the heating body 10 is reduced. The aerosol precursor is easier to reach the atomizing surface 12 and be atomized. The probability of dry burning of the heating body 10 can be reduced.

Referring to FIG. 13, in some embodiments, the fin 221 defines a passing hole 222. The passing hole 222 passes through opposite sides of the fin 221 in a direction of the thickness of the fin 221. Thus, the through the hole 222 reduces the flow resistance of the aerosol precursor, so that the aerosol precursor can smoothly pass through the through hole 211 and the flow channel 13 to reach the atomizing surface 12. In particular, the number of passing hole 222 in each of the fins 221 can be one or multiple. The passing hole 222 can be round-shaped, square-shaped, stripped-shaped and other shapes. This application does not limit the specific shape of the passing hole 222.

Referring to FIG. 4, in some embodiments, the heating element 20 is thermally connected with the heating body 10. The heat of the heating body 10 can be transferred to the heating element 20. Thus, after heat exchange between the heating element 20 and the heating body 10, the temperature of the heating element 20 increases, so that the aerosol precursor can be heated.

It should be noted that the heating element 20 is thermally connected with the heating body 10, which the heating element 20 and the heating body 10 can be directly connected to each other, or the heating element 20 and the heating body 10 can be indirectly connected through an intermediate medium, as long as the heating body 10 can transfer heat to the heating element 20.

Referring to FIG. 4 and FIG. 5, in some embodiments, the atomization device 100 includes a flow stabilizer 30 arranged between the heating element 20 and the heating body 10. The flow stabilizer 30 can transfer the heat of the heating body10 to the heating element 20.

Thus, the flow stabilizer 30 can not only stabilize the flow rate of the aerosol precursor, but also prevent the heating body 10 from leaking, so that the aerosol precursor can flow more evenly through the flow channel 13 to the atomizing surface 12 and be atomized. The flow stabilizer 30 also can transfer the heat of the heating body 10 to the heating element 20, so that the temperature of the heating element 20 can be increased.

In particular, the flow stabilizer 30 is a component with multiple holes, which can be arranged regularly or irregularly. The flow stabilizer 30 can be arranged in a thin sheet and stacked with the heating body 10. The base 21 of the heating element 20 can be pressed against the flow stabilizer 30, so that the contact area between the flow stabilizer 30 and the heating element 20 is larger, which is conducive to transfer the heat of the heating body 10 through the flow stabilizer 30 to the heating element 20.

In some embodiments, the flow stabilizer 30 can be a cotton flow stabilizer or a metal flow stabilizer. When the flow stabilizer 30 is a cotton flow stabilizer, the flow stabilizer 30 is made of cotton material, and the heating body 10 can transfer heat to the heating element 20 through the aerosol precursor adsorbed on the cotton flow stabilizer. When the flow stabilizer 30 is a metal flow stabilizer, the flow stabilizer 30 is made of metal material, and the heating body 10 can transfer heat to the heating element 20 through the aerosol precursor on the metal flow stabilizer and the metal flow stabilizer.

Referring to FIG. 14 and FIG. 15, in some embodiments, the heating element 20 is configured to generate heat when the heating element 20 is energized. Thus, the heating element 20 can convert electrical energy into heat energy. The temperature of the heating element 20 can be higher, and the heat emitted by the heating element 20 is more, so as to rapidly heat the aerosol precursor. The temperature rise of the aerosol precursor is larger, which is conducive to the viscosity of the aerosol precursor to decrease, thereby increasing the fluidity of the aerosol precursor.

In particular, as discussed above, the heating element 20 can be made of metal material. Due to metal material have a certain resistance, the heating element 20 can effectively convert electrical energy into heat energy.

Referring to FIG. 14 and FIG. 15, in some embodiments, the heating element 20 is configured to contact an electrode terminal 40 of the atomization device 100, so that the electrode terminal 40 supplies power to the heating element 20. The electrode terminal 40 is used to contact the atomizing surface 12. Thus, the electrode terminal 40 can supply power to the heating body 10 and the heating element 20 at the same time. Alternatively, the heating body 10 and the heating element 20 can share the same electrode terminal 40, which can reduce the number of components of the atomization device 100, thereby making the atomization device 100 more compact.

In particular, the number of the electrode terminals 40 can be two. The electrode terminals 40 includes a positive electrode terminal and a negative electrode terminal. The positive electrode terminal can be connected to the positive terminal of the power supply. The negative terminal can be connected to the negative terminal of the power supply. The power supply supplies power to the heating element 20 and the heating body 10 through the positive electrode terminal and the negative electrode terminal, so that the heating body 10 and the heating element 20 can generate heat.

Referring to FIG. 15, in some embodiments, the heating body 10 defines a penetrating hole 16. The penetrating hole 16 is configured for passing through the electrode terminal 40, so that the electrode terminal 40 is in contact with the heating element 20. As mentioned above, the heating element 20 is disposed on one side of the liquid absorbing surface 11, and the electrode terminal 40 is in contact with the atomizing surface 12. The penetrating hole 16 is formed on the heating body 10, so that one end of the electrode terminal 40 is in contact with the heating element 20, therefore the electrode terminal 40 supplies power to the heating element 20.

In detail, the electrode terminal 40 is generally cylindrical, and the size of the penetrating hole 16 can be slightly larger than that of the electrode terminal 40. The electrode terminal 40 can pass through the hole 16 to avoid the leakage of the aerosol precursor from the penetrating hole 16.

It can be understood that the electrode terminal 40 passes through the flow stabilizer 30 and is connected to the heating element 20 when the flow stabilizer 30 is arranged between the heating body 10 and the heating element 20.

Referring to FIG. 16, in some embodiments, the heating element 20 includes a base 21 and an electrical connecting portion 23 connected to the base 21. The base 21 is located on one side of the liquid absorbing surface 11. The electrical connecting portion 3 extends from the base 21 to the atomizing surface 12 and contacts the electrode terminal 40. Thus, the electrical connecting portion 23 can couple the heating element 20 with the electrode terminal 40, so that the electrode terminal 40 supplies power to the heating element 20, therefore the heating element 20 can heat the aerosol precursor.

In particular, the material of the electrical connecting portion 23 can be the same as that of the base 21. The electrical connecting portion 23 and the base 21 can be formed by a die casting process and/or a stamping process. The electrical connecting portion 23 can extends from the side of the heating body 10 to the atomizing surface 12, so that the structure of the heating body 10 cannot be damaged, and the aerosol precursor can flow stably to the atomizing surface 12.

Referring to FIG. 16, in some embodiments, the electrical connecting portion 23 includes a first connecting sheet 231 and a second connecting sheet 232. The first connecting sheet 231 is coupled with the base 21 and the second connecting sheet 232. The second connecting sheet 232 is bent relative to the first connecting sheet 231. The second connecting sheet 232 is located on a side of the atomizing surface 12. The second connecting sheet 232 is configured for contacting the electrode terminal 40. Thus, the first connecting sheet 231 and the second connecting sheet 232 are matched, so that the electrical connecting portion 23 extends from the base 21 to the atomizing surface 12, and the electrical connecting portion 23 is connected to the electrode terminal 40 through the second connecting sheet 232.

In particular, the first connecting sheet 231, the second connecting sheet 232, and the base 21 can jointly form a clamping room 233. The heating body 10 and the flow stabilizer 30 are accommodated in the clamping room 233. Thus, the clamping room 233 can make the heating body 10, the heating element 20, and the flow stabilizer 30 form a whole, which is conducive to the installation of the heating body 10, the heating element 20, and the flow stabilizer 30.

Referring to FIG. 4 and FIG. 5, in some embodiments, the atomization device 100 further includes a core holder 50. The heating body 10 and the heating element 20 are installed inside the core holder 50. Thus, the heating body 10 can be connected to the heating element 20 more stably.

The liquid outlet channel 51 is a channel through which the aerosol precursor flows from the liquid storage chamber 61 to the heating body 10. Under the action of gravity, air pressure and other forces, the aerosol precursor enters the liquid outlet channel 51 from one end, and flows to the heating body 10 from the other end of the liquid outlet channel 51.

The aerosol outlet channel 52 is a channel which the aerosol formed by the aerosol precursor of the heating body 10 is exported to the outside of the core holder 50. Alternatively, the aerosol formed by the aerosol precursor can flow to the outside of the core holder 50 through the aerosol outlet channel 52.

The aerosol outlet channel 52 and the liquid outlet channel 51 are crossed and isolated. For example, the liquid outlet channel 51 is arranged on a first side of the core holder 50. The aerosol outlet channel 52 is arranged on a second side of the core holder 50. The first side is substantially perpendicular to the second side. As shown in an orientation of the figure, the liquid outlet channel 51 is arranged on the left and right sides of the core holder 50. The aerosol outlet channel 52 is arranged on the front and rear sides of the core holder 50.
