DETAILED DESCRIPTION

[0043] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] Embodiment 1:

[0045] See also Figure 1 and Figure 2 The embodiment of the present invention provides an atomizer core 1, which is applied to an electronic atomizer 4 and is used to heat a liquid aerosol-generating matrix to generate an aerosol. The atomizer core 1 includes: an oil guide member 2, which has an oil absorption surface 201 and a heating surface 202 disposed opposite to each other and a through hole 203 penetrating the oil absorption surface 201 and the heating surface 202; a heating member 3, which is attached to the heating surface 202 and is disposed around the through hole 203; wherein the heating member 3 heats the aerosol-generating matrix on the heating surface 202 to generate an aerosol, and the aerosol passes through the through hole 203.

[0046] In this embodiment, the atomizer core 1 includes an oil guide member 2 and a heating member 3; wherein the oil guide member 2 has an oil absorption surface 201 and a heating surface 202 arranged opposite to each other and a through hole 203 penetrating the oil absorption surface 201 and the heating surface 202, the oil absorption surface 201 is used to absorb the smoke oil in the electronic atomizer 4, and the oil guide member 2 is used to guide the smoke oil at the liquid absorption surface to the heating surface 202.

[0047] The oil guide member 2 is a ceramic or silicon sheet or glass sheet with micropores, or a fiber material such as cotton, and the thickness of the oil guide member 2 can be adjusted according to the needs. The heating element 3 is attached to the heating surface 202 of the oil guide member 2 to atomize the tobacco oil at the heating surface 202. When the tobacco oil is atomized, it will flow into the end of the through hole 203 close to the heating surface 202, and then flow out from the end of the through hole 203 close to the oil absorption surface 201.

[0048] The connection method between the heating element 3 and the oil guide member 2 includes abutment or embedding connection. When the two are fixedly connected, they can be made into a standard part of the atomizer core 1. When assembled in the electronic atomizer 4 later, there is no need to assemble in two steps, which saves assembly time. If the abutment method is adopted, it is convenient to repair and replace the heating element 3 or the oil guide member 2. At the same time, the heating element 3 is attached to the heating surface 202 and arranged around the through hole 203, which is conducive to the rapid flow of the atomized smoke oil into the through hole 203, and is conducive to the uniform atomization of the smoke oil around the through hole 203, avoiding the problem of low smoke oil atomization efficiency in the local area of ​​the heating surface 202.

[0049] In the present invention, the heating element 3 is arranged on the heating surface 202 of the oil guide 2 to atomize the smoke oil, and a through hole 203 is opened on the oil guide 2 to form a smoke channel, so that the smoke generated on the heating surface 202 can be transported to the smoke pipe 502 through the smoke channel. After the heating element 3 is arranged on the heating surface 202 of the oil guide 2, the present invention only needs to open a through hole 203 on the oil guide 2 to transport the smoke. Compared with the traditional atomizer core 1, the assembly structure is simpler, the assembly efficiency is higher, and a certain cost is saved.

[0050] As a further solution, the heating element 3 includes at least two conductive electrode sheets 301 and a heating mesh sheet 302 connected between two adjacent conductive electrode sheets 301. The heating mesh sheet 302 is arranged around the through hole 203. Specifically, the conductive electrode sheet 301 and the heating mesh sheet 302 are respectively attached to the heating surface 202 of the oil guide member 2, and the conductive electrode sheet 301 is used to conduct electricity to the heating mesh sheet 302, so that the heating mesh sheet 302 is heated. After heating, the heating mesh sheet 302 can atomize the tobacco oil on the heating surface 202. By surrounding the heating mesh sheet 302 around the through hole 203, the heating mesh sheet 302 can cooperate with the heating surface 202 to quickly guide the atomized tobacco oil into the through hole 203.

[0051] As a further solution, the oil guide 2 is cylindrical, the heating mesh 302 is fan-shaped, and the heating mesh 302 is laid out with the axis of the through hole 203 as the center. Specifically, the oil guide 2 includes but is not limited to cylindrical, truncated cone, directional and other shapes, and can be adaptively adjusted according to actual needs. The heating mesh 302 is fan-shaped or semicircular, and has a mesh shape. The mesh shape can be polygonal, wavy, etc. The heating mesh 302 is laid out with the axis of the through hole 203 as the center, and the side of the heating mesh 302 away from the through hole 203 is flush with the periphery of the heating surface 202, so as to maximize the area of ​​the heating mesh 302, cover a wider range of the heating surface 202, improve the efficiency of the heating mesh 302 in atomizing the smoke oil, and then improve the atomization efficiency and performance of the atomization core 1.

[0052] In this embodiment, the heating element 3 includes two conductive electrode sheets 301 and a heating mesh 302, and the two ends of the heating mesh 302 are respectively electrically connected to the two conductive electrode sheets 301. For example, one conductive electrode sheet 301 is a positive electrode sheet, and the other conductive electrode sheet 301 is a negative electrode sheet. The two conductive electrode sheets 301 are symmetrically arranged on the heating surface 202, and the heating mesh 302 is located between the two conductive electrode sheets 301, and the two ends of the heating mesh 302 are respectively connected to the two conductive electrode sheets 301 for power supply.

[0053] The axis of the through hole 203 is parallel to the axis of the oil guide member 2 and is arranged in parallel and at intervals, that is, the through hole 203 in this embodiment is not coaxial with the oil guide member 2, and the central axis of the through hole 203 is an eccentric axis relative to the central axis of the oil guide member 2. By setting the through hole 203 as an eccentric axis, the area of ​​the heating surface 202 with the smoke oil can be more concentrated, which is more convenient for the heating mesh 302 to cover, thereby improving the atomization efficiency of the atomization core 1. At the same time, the through hole 203 in this embodiment can also be coaxially arranged with the oil guide member 2. The two conductive electrode sheets 301 are respectively located on opposite sides of the through hole 203. The two conductive electrode sheets 301 in this embodiment only need to keep non-contact with each other. The spacing between the two conductive electrode sheets 301 can be adaptively adjusted. The smaller the spacing between the two conductive electrode sheets 301, the larger the area of ​​the heating mesh 302. Therefore, the staff can make adaptive changes to the structure of the heating element 3 according to the requirements of the atomization efficiency of the atomization core 1.

[0054] As a further solution, the heating element 3 may include three conductive electrode sheets 301 and two heating mesh sheets 302, and each heating mesh sheet 302 is electrically connected to two adjacent conductive electrode sheets 301. The axis of the through hole 203 is arranged to coincide with the axis of the oil guide member 2, and the two heating mesh sheets 302 are arranged around the through hole 203. Specifically, the heating element 3 in this embodiment includes three conductive electrode sheets 301 and two heating mesh sheets 302, one of which is used as a common conductive electrode sheet 301, and the common conductive electrode sheet 301 can form a separate heating circuit with one of the other two conductive electrode sheets 301, and the two heating mesh sheets 302 are respectively connected between the two heating circuits to form two separate double-emission atomization structures.

[0055] For example, when the common conductive electrode sheet 301 is a positive electrode sheet, the other two conductive electrode sheets 301 are negative electrode sheets, and a heating mesh sheet 302 is connected between a negative electrode sheet and a positive electrode sheet, and another heating mesh sheet 302 is connected between another negative electrode sheet and a positive electrode sheet; by adding a conductive electrode sheet 301 and a heating mesh sheet 302, the atomization efficiency of the atomizer core 1 for the e-liquid can be further improved. At the same time, the number of through holes 203 includes but is not limited to one, and can be two, three, etc., to form a single-shot, double-shot, triple-shot, etc. smoke channel structure, which accelerates the circulation efficiency of the atomized e-liquid.

[0056] Embodiment 2:

[0057] See also Figure 3-Figure 16 The embodiment of the present invention further provides an electronic atomizer 4, which includes an oil cup assembly 5 and an atomizer core 1 as in any one of the first embodiments. The atomizer core 1 is arranged in the oil cup assembly 5 and the oil absorption surface 201 of the oil guide 2 is in contact with the oil storage cotton 503 in the oil cup assembly 5. Figure 8 Specifically, the oil cup assembly 5 is used to store the smoke oil, and the atomizer core 1 is located in the oil cup assembly 5. The oil absorption surface 201 of the oil guide 2 can absorb the smoke oil in the oil storage cotton 503 after contacting the oil storage surface. At the same time, oil absorption cotton (not shown) can be arranged between the oil absorption surface 201 and the oil storage cotton 503. The oil absorption cotton can speed up the efficiency of smoke oil transfer, and the oil absorption cotton can more thoroughly absorb the smoke oil in the oil storage cotton 503, so that the utilization rate of the smoke oil is improved and waste is reduced.

[0058] like Figure 4-Figure 8 As shown, in this embodiment, the oil cup assembly 5 includes a cup body 501, a smoke pipe 502 and an oil storage cotton 503. The cup body 501 has an oil storage cavity 5011 built in it and one side is open, and the other side of the cup body 501 is also provided with a smoke outlet 5012; the smoke pipe 502 is arranged in the cup body 501, and one end is connected to the smoke outlet 5012, and the other end is connected and connected to the through hole 203. The oil storage cotton 503 is arranged in the oil storage cavity 5011 and wraps the smoke pipe 502 inside.

[0059] Specifically, the smoke outlet 5012 in this embodiment is arranged opposite to the opening side of the cup body 501, and the smoke pipe 502 is a straight pipe, which is conducive to the rapid discharge of the atomized smoke oil from the smoke pipe 502. The diameter of the smoke pipe 502 in this embodiment is larger than the diameter of the through hole 203, the smoke pipe 502 is in contact with the oil absorption surface 201, and the through hole 203 and the smoke pipe 502 are coaxially arranged. The simple connection method between the two can speed up the assembly efficiency of the electronic atomizer 4; or, the diameter of the smoke pipe 502 is smaller than the diameter of the through hole 203, and one end of the smoke pipe 502 extends into the through hole 203, and the two are interference fit. This connection method makes the connection between the smoke pipe 502 and the through hole 203 more tightly, and the structure of the connection between the two is more stable. The oil storage cotton 503 wraps the smoke pipe 502 to position and protect the smoke pipe 502, and the oil storage cotton 503 can be preset with a mounting hole (not shown) for mounting the smoke pipe 502, making it more convenient to assemble the two.

[0060] like Figure 9-13As shown, as a further solution, the electronic atomizer 4 further includes: a support member 6 and a sealing base 7. One end of the support member 6 is open and has a built-in support cavity 601. The diameter of the opening of the support member 6 is slightly larger than the diameter of the oil guide member 2. The support cavity 601 is used to accommodate the atomization core 1. A support portion 602 is provided in the support cavity 601. The support member 6 is also provided with an airflow hole 603 that runs through its side and a first connecting portion 604 that is provided on the outside of the support member 6. A plurality of airflow holes 603 can be provided, such as 2, 3, 4, etc., and when a plurality of airflow holes 603 are provided, the spacing between the airflow holes 603 is uniform, and the more the number of airflow holes 603 or the larger the aperture, the faster the atomized smoke oil flows.

[0061] The support member 6 is covered on the atomizer core 1, and the side periphery of the oil guide member 2 abuts against the side wall of the support cavity 601, see Fig.12 , the heating surface 202 of the oil guide member 2 abuts against the support plate, and the through hole 203 is connected to the support cavity 601. The support member 6 is used to support and protect the atomizer core 1. At the same time, the airflow hole 603 is connected to the through hole 203 through the support cavity 601, so that the external airflow can pass into the support cavity 601 and flow to the through hole 203. When the heating mesh 302 atomizes the smoke oil, the atomized smoke oil is accumulated in the support cavity 601. When the external airflow flows into the support cavity 601 through the airflow hole 603, the external airflow drives the atomized smoke oil to flow into the through hole 203 and flow to the smoke pipe 502 and the smoke outlet 5012.

[0062] At the same time, the sealing base 7 is provided with a limiting hole 701 and a second connecting portion 702 adapted to the support member 6. The sealing base 7 is sleeved on the support member 6 through the limiting hole 701 and is arranged on the open side of the cup body 501, so as to enclose the cup body 501 to form an oil storage chamber and seal the open side of the cup body 501. The sealing base 7 has a certain elasticity, and the limiting hole 701 is interference fit with the support member 6, so as to reinforce the support member 6 with the hoop reinforcement. The oil storage cotton 503 is arranged in the oil storage chamber (not shown), and the oil storage chamber is the space formed after the sealing base 7 seals one side of the opening of the oil storage cavity 5011. The first connecting portion 604 and the second connecting portion 702 are detachably connected, and the sealing base 7 limits and fixes the support member 6 through the cooperation of the first connecting portion 604 and the second connecting portion 702.

[0063] In this embodiment, the first connection part 604 is a clamping block, and the second connection part 702 is an elastic clamping groove. The clamping block and the clamping groove are clamped together, so that the sealing base 7 can limit and fix the support member 6. At the same time, the sealing base 7 is clamped with the cup body 501, that is, the side of the sealing base 7 close to the cup body 501 is interference-fitted with the cup body 501, so as to facilitate the subsequent disassembly of the sealing base 7.

[0064] like Fig.14 and Fig.15As shown, as a further solution, the heating element 3 also includes at least two conductive ejector pins 303, and the at least two conductive ejector pins 303 are arranged in a one-to-one correspondence with the at least two conductive electrode sheets 301; a through hole 605 for passing the conductive ejector pin 303 is provided on the side of the support member 6 opposite to its opening side, and one end of each conductive ejector pin 303 passes through the through hole 605 and extends out of the support member 6, and the other end of each conductive ejector pin 303 is connected to the corresponding conductive electrode sheet 301. Specifically, in this embodiment, two conductive ejector pins 303 and two conductive electrode sheets 301 are provided respectively, and the two conductive ejector pins 303 are connected to the two conductive electrode sheets 301 one by one, and the two conductive ejector pins 303 are respectively used to connect the external power supply to the conductive electrode sheets 301; the number of conductive ejector pins 303 is consistent with the number of conductive electrode sheets 301. If the number of conductive electrode sheets 301 is three, the number of conductive ejector pins 303 is also three; the connection method between the conductive ejector pin 303 and the conductive electrode sheet 301 can be abutment or welding fixation; when the connection method between the two is abutment, it is convenient to disassemble and replace damaged parts. For example, when the conductive ejector pin 303 is damaged, the conductive ejector pin 303 can be directly replaced; if the two methods are welding fixation, the installation steps of the conductive ejector pin 303 are saved, and the assembly is more efficient.

[0065] like Fig.16 As shown, in this embodiment, the electronic atomizer 4 also includes: a bottom cover 8; the bottom cover 8 is detachably arranged on the side of the sealing base 7 away from the liquid storage chamber, for example, an elastic buckle (not shown) is arranged on the bottom cover 8, and a corresponding buckle position (not shown) is arranged on the sealing base 7, and the two are connected with the buckle position through the elastic buckle; an air inlet groove 703 is also arranged on the side of the sealing base 7 close to the bottom cover 8. After the bottom cover 8 and the sealing base 7 are surrounded, an air inlet cavity (not shown) is formed at the position where one side of the bottom cover 8 cooperates with the air inlet groove 703, and the air flow hole 603 is connected with the air inlet cavity; an air inlet hole 801 is also arranged on the bottom cover 8, and the air inlet hole 801 connects the outside with the air inlet cavity; an embedding hole 802 adapted to the conductive ejector pin 303 is arranged on the bottom cover 8, and one end of the conductive ejector pin 303 away from the conductive electrode sheet 301 is embedded in the embedding hole 802, and the base limits and fixes the conductive ejector pin 303 through the embedding hole 802.

In the present invention, the e-liquid is atomized by disposing the heating member 3 on the heating surface 202 of the oil guide member 2, and a through hole 203 is provided on the oil guide member 2 to form a smoke channel, so that the smoke generated on the heating surface 202 can be transported to the smoke pipe 502 through the smoke channel. After the heating element 3 is arranged on the heating surface 202 of the oil guide element 2, the invention only needs to open a through hole 203 on the oil guide element 2 to transport the smoke. Compared with the traditional atomizer core 1, the assembly structure is simpler, the assembly efficiency is higher and a certain cost is saved.
