DETAILED DESCRIPTION

[0032] The following are preferred implementations of the present application. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.

[0033] In view of this, in order to solve the above problems, this application provides an atomizer core substrate, please refer to Figure 1-Figure 5 , Figure 1 It is a schematic diagram of the three-dimensional structure of the atomizer core substrate in one embodiment of the present application. Figure 2 for Figure 1 A schematic diagram of the three-dimensional structure of the atomizer core substrate from another perspective is shown. Figure 3 for Figure 2 The scanning electron microscope image of the atomizer core substrate shown in the top view. Figure 4 In one embodiment of the present application Figure 3 The schematic diagram of the partial enlargement of the scanning electron microscope image of the atomizer core substrate shown. Figure 5 In another embodiment of the present application Figure 3 The atomizer core substrate 11 provided in this embodiment is applied to the atomizer device 3, and the atomizer core substrate 11 includes a plurality of skeleton members 111 and a plurality of support members 112, wherein the skeleton members 111 are needle-shaped, and the support members 112 are spherical or quasi-spherical, and the plurality of skeleton members 111 and the plurality of support members 112 cooperate with each other to form a three-dimensional network structure, thereby forming a liquid guide channel 114 in the atomizer core substrate 11.

[0034] The atomizer core substrate 11 is one of the important components in the atomizer device 3. The liquid to be atomized is placed in the oil tank. A liquid inlet hole is provided between the oil tank and the atomizer core substrate 11. The liquid to be atomized can contact the atomizer core substrate 11 through the liquid inlet hole. The atomizer core substrate 11 is not a very dense component inside. On the contrary, the atomizer core 10 has abundant pores and channels inside. The liquid to be atomized can be transmitted inside the atomizer core substrate 11 through these pores and channels until it is transmitted to the heating element 12. When the heating element 12 is working, it can heat and atomize the liquid to be atomized, converting it into an aerosol, and then discharge it through the air guide channel for users to use or inhale.

[0035] The oil conducting ability and oil locking ability of the atomizer core matrix 11 determine the performance of the atomizer core matrix 11. The oil conducting ability refers to the speed at which the atomized liquid is transmitted inside the atomizer core matrix 11, and the oil locking ability refers to the ability of the atomizer core matrix 11 to stably store the atomized liquid, and to lock the atomized liquid well inside the atomizer core matrix 11 to prevent it from leaking.

[0036] In the related art, the atomizer core substrate 11 is usually made of silicon oxide, which is spherical or quasi-spherical, where the quasi-spherical shape can be understood as an elliptical or other spherical-like shapes. Multiple silicon oxides are tightly connected to each other, and only very small pores are formed between adjacent silicon oxides, resulting in a very low porosity and poor oil conduction capacity.

[0037] The atomizer core substrate 11 provided in this embodiment has a skeleton member 111 added on the basis of the support member 112, the skeleton member 111 is needle-shaped, and the support member 112 is spherical or quasi-spherical. The skeleton member 111 refers to the main component of the atomizer core substrate 11, which serves as the skeleton of the atomizer core substrate 11. The skeleton member 111 is needle-shaped, has a slender shape like a needle, and has a certain aspect ratio. Optionally, the material of the skeleton member 111 can be silicate. Further optionally, the silicate can include wollastonite, mullite, etc. The support member 112 refers to the main supporting role, the support member 112 is spherical or quasi-spherical, and the spherical or quasi-spherical shape can play a good supporting role. Optionally, the material of the support member 112 can be an alkali metal oxide. Further optionally, the material of the support member 112 includes silicon oxide, aluminum oxide, silicon carbide, etc.

[0038] The spherical support member 112 can be used as a support node, the needle-shaped skeleton member 111 is overlapped on the support member 112, and multiple skeleton members 111 can be interwoven and matched with each other to finally build a three-dimensional mesh structure. Compared with the atomizer core matrix 11 that is completely made of support members 112, there are fewer pores inside the atomizer core matrix 11, and compared with the atomizer core matrix 11 that is completely made of skeleton members 111, if the bending direction of the skeleton members 111 is consistent, it will be difficult to form a support space. The atomizer core matrix 11 provided in this embodiment can not only be built into a three-dimensional mesh support space inside, but also has abundant pores inside the three-dimensional mesh, thereby increasing the porosity of the atomizer core matrix 11 and improving the oil conduction capacity. The improvement in oil conduction capacity can also be understood from another perspective as being blocked by a needle-shaped skeleton member 111 with a smaller thickness between two adjacent pores and channels. Compared with the spherical support member 112 with a larger thickness, the atomized liquid is easier to pass through the skeleton member 111. In addition, the three-dimensional mesh structure formed by the needle-shaped skeleton member 111 and the spherical support member 112 can increase the specific surface area inside the atomizer core substrate 11, so that the liquid to be atomized can be better locked in the three-dimensional mesh, thereby preventing the liquid to be atomized from leaking out and improving the oil locking ability.

[0039] Optionally, in addition to the frame member 111 and the support member 112, the atomizer core substrate 11 may also include a plurality of bonding members 113, and the bonding members 113 are used to better fix the frame member 111 and the support member 112, and the frame members 111 and the frame members 111 together to form a stable three-dimensional network structure.

[0040] In this embodiment, the atomizer core substrate 11 composed of the plurality of skeleton members 111 and the plurality of support members 112 has a first porosity, and the atomizer core substrate 11 composed of the plurality of support members 112 has a second porosity, which is smaller than the first porosity.

[0041] From the above content, it can be seen that the porosity of the atomizer core substrate 11 mainly composed of a plurality of spherical support members 112 in the related art is relatively small, which is the second porosity, while the porosity of the three-dimensional network structure formed by the cooperation of a plurality of skeleton members 111 and the plurality of support members 112 in this embodiment is the first porosity, and the first porosity is greater than the second porosity, which also proves that the atomizer core substrate 11 provided in this embodiment has a higher porosity.

[0042] In this embodiment, the first porosity is 45%-55%, which greatly increases the number of pores inside the atomizer core matrix 11 and improves the oil-conducting capacity. Since the number of pores is provided by the three-dimensional network structure, the three-dimensional network structure greatly increases the specific surface area inside the atomizer core matrix 11, thereby improving the oil-locking capacity.

[0043] Alternatively, the first porosity may be 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, or 55%.

[0044] Please refer again Figure 4-Figure 5 In this embodiment, the liquid conducting channel 114 includes a first sub-liquid conducting channel 114a and a second sub-liquid conducting channel 114b which are interconnected. The first sub-liquid conducting channel 114a is formed within the three-dimensional network structure, and the second sub-liquid conducting channel 114b is in the shape of a hole and is formed after the pore-forming agent is removed.

[0045] As can be seen from the above, the inside of the atomizer core substrate 11 has a rich liquid-conducting channel 114 formed by interconnected pores. In this embodiment, the liquid-conducting channel 114 can be divided into two parts, the first part is the first sub-liquid-conducting channel 114a, and the first sub-liquid-conducting channel 114a is the channel formed inside the three-dimensional mesh structure mentioned above. The second part is the second sub-liquid-conducting channel 114b, and pore-forming agents such as polystyrene, paraffin, beeswax, polyethylene, and stearic acid are added during the preparation of the atomizer core substrate 11. These pore-forming agents will occupy a certain space inside the atomizer core substrate 11 during the addition process. However, in the subsequent sintering process, these pore-forming agents will be removed from the atomizer core substrate 11 by various means such as decomposition and volatilization. After removal, the space originally occupied by these pore-forming agents will become holes, thereby forming a hole-shaped second sub-liquid-conducting channel 114b. The first sub-liquid-conducting channel 114a and the second sub-liquid-conducting channel 114b are interconnected to form the liquid-conducting channel 114 in the atomizer core substrate 11.

[0046] In this embodiment, the aspect ratio of the needle-shaped skeleton member 111 is (10-15): 1. The length of the slender needle-shaped skeleton member 111 is always larger than the diameter, but if the aspect ratio of the skeleton member 111 is too large, for example, greater than 15: 1, the skeleton member 111 will be too long, resulting in a decrease in the strength of the skeleton member 111, which is easy to break, thereby affecting the overall performance of the atomizer core substrate 11. However, if the aspect ratio of the skeleton member 111 is too small, for example, less than 10: 1, the skeleton member 111 will be too short, reducing the porosity inside the three-dimensional mesh structure, thereby affecting the overall porosity of the atomizer core substrate 11, and affecting the oil conduction and oil locking capabilities.

[0047] Optionally, the aspect ratio of the framework member 111 may be 10:1, 11:1, 12:1, 13:1, 14:1, or 15:1.

[0048] Please refer again Figure 1-Figure 2 In this embodiment, the atomizer core substrate 11 is cylindrical, and a through hole 115 is provided on the atomizer core substrate 11 along the axial direction of the atomizer core substrate 11. The atomizer core substrate 11 has an outer peripheral side surface 116 and an inner peripheral side surface 117 that are arranged opposite to each other, and the outer peripheral side surface 116 constitutes a liquid absorption surface.

[0049] The overall structure of the atomizer core substrate 11 is an annular cylindrical shape, that is, the atomizer core substrate 11 is cylindrical as a whole, but in the axial direction of the atomizer core substrate 11, that is, along the length direction of the atomizer core substrate 11, a through hole 115 can be opened inside the atomizer core substrate 11, and the through hole 115 is used to gather the aerosol generated by the liquid to be atomized, and then the aerosol is transmitted to the air guide channel through the through hole 115.

[0050] The annular cylindrical atomizer core substrate 11 has an outer peripheral side surface 116 and an inner peripheral side surface 117 disposed opposite to each other, wherein the outer peripheral side surface 116 is the outer surface of the atomizer core substrate 11, and is also the surface of the atomizer core substrate 11 in contact with the liquid to be atomized. The liquid to be atomized enters the interior of the atomizer core substrate 11 through the outer peripheral side surface 116 and is transmitted within the atomizer core substrate 11. At this time, the outer peripheral side surface 116 can also be referred to as a liquid absorption surface. The heating element 12 can be disposed on the inner peripheral side surface 117, or embedded in the atomizer core substrate 11. When the liquid to be atomized is transmitted to the heating element 12, the heating element 12 can atomize it into an aerosol, and the aerosol is then transmitted to the through hole 115, and finally used or inhaled by the user through the air guide channel.
