Description

Technical Field

[0001] This invention relates to the field of atomizer technology, and particularly to an atomizing core and atomizing device. Background Technology

[0002] Atomizer cores made from porous ceramics are typically hollow cylinders. To stabilize the e-liquid flow rate of porous ceramics, absorbent cotton can be wrapped around their outer periphery to absorb the matrix. However, because existing porous ceramic structures are regular cylinders, the absorbent cotton is prone to misalignment during the wrapping process, and it is also prone to falling off or flipping after assembly, leading to unstable e-liquid flow. Therefore, providing an atomizer core that prevents misalignment of the absorbent cotton during assembly and avoids detachment or flipping has become an urgent technical problem to be solved. Summary of the Invention

[0003] This application provides an atomizing core that can solve the problems of misalignment during the process of wrapping the oil-guiding cotton, and the oil-guiding cotton easily falling off or flipping over after assembly.

[0004] To solve the above-mentioned technical problems, this application provides an atomizing core, including a porous body and a heating element. The porous body has an atomizing cavity that runs longitudinally through the porous body, and the heating element is installed in the atomizing cavity. The porous body has a first end near the air intake end of the atomizing core and a second end opposite to the first end. The first end and the second end are respectively provided with limiting members. The limiting members protrude from the porous body in the radial direction. The area between the limiting member at the first end and the limiting member at the second end forms an installation position for positioning and installing oil-guiding cotton.

[0005] This application also provides an atomizing device, which includes an oil tank and an atomizing core as described above. An air passage is provided inside the oil tank, and the atomizing core is installed inside the air passage. The air passage is connected to the atomizing chamber of the atomizing core. The oil tank is provided with an oil storage chamber, which stores a matrix. Oil-guiding cotton is wrapped between the limiting members of the porous body, and the matrix can flow to the porous body through the oil-guiding cotton. The heating element heats the matrix to generate an aerosol.

[0006] The atomizing core provided in this application has limiting members at opposite ends of the porous body. The limiting members protrude from the porous body in the radial direction, thereby forming enlarged ends at both ends of the porous body. When the oil-guiding cotton is wrapped around the outer periphery of the porous body, the enlarged ends define the installation position of the oil-guiding cotton, which can prevent misalignment during the assembly of the oil-guiding cotton. The limiting members can restrict the oil-guiding cotton from moving longitudinally along the atomizing core, preventing the oil-guiding cotton from falling off or turning over.

[0016] This application provides an atomizing coil. Please refer to [link / reference]. Figure 1 , Figure 2 The atomizing core 100 may include a porous body 10 and a heating element 20. The porous body 10 may be made of porous ceramic, which has good liquid conductivity. The porous body 10 can adsorb the matrix, and the heating element 20 heats the matrix to generate an aerosol. An atomizing chamber 11 is provided inside the porous body 10, extending longitudinally through the atomizing core 10, and the heating element 20 is installed inside the atomizing chamber 11. The porous body 10 has a first end 12 near the air intake end of the atomizing core 100 and a second end 13 opposite to the first end 12. The first end 12 and the second end 13 are respectively provided with limiting members 30. The limiting members 30 protrude from the porous body 10 in the radial direction. The area between the limiting member 30 at the first end 12 and the limiting member 30 at the second end 13 forms a mounting position for positioning and installing the oil-guiding cotton.

[0017] The atomizing core 100 provided in this application has limiting members 30 at opposite ends of the porous body 10. The limiting members 30 protrude radially from the porous body 10, thereby forming enlarged ends at both ends of the porous body 10. When the oil-guiding cotton is wrapped around the outer periphery of the porous body 10, the enlarged ends define the installation position of the oil-guiding cotton, which can prevent misalignment during the assembly of the oil-guiding cotton. After the oil-guiding cotton is assembled, the limiting members 30 can restrict the oil-guiding cotton from moving longitudinally along the atomizing core 100, thereby preventing the oil-guiding cotton from falling off or turning over.

[0018] The limiting member 30 can be configured in various ways. In one embodiment, the limiting member 30 is a flange 31, which circumferentially surrounds the porous body 10, such as... Figure 1 , Figure 2 As shown. Flanges 31 are connected to the outer wall of the porous body 10. The flanges 31 at both ends of the porous body 10 and the outer wall of the porous body 10 define the mounting position of the oil-guiding cotton, preventing misalignment during assembly. After assembly, if the oil-guiding cotton moves longitudinally along the atomizing core 100, the flanges 31 at both ends provide supporting reaction force to prevent the oil-guiding cotton from moving longitudinally along the atomizing core 100, thereby preventing the oil-guiding cotton from falling off or flipping over.

[0019] In another embodiment, the limiting member 30 is a protruding tooth 32, and multiple protruding teeth 32 are spaced apart on the outer periphery of the porous body 10, such as... Figure 3 As shown. Similarly, the protruding teeth 32 located at both ends of the porous body 10 and the outer wall of the porous body 10 define the mounting position of the oil-guiding cotton, which can prevent misalignment during the assembly of the oil-guiding cotton. After the oil-guiding cotton is assembled, the protruding teeth 32 provide a supporting reaction force for the oil-guiding cotton to prevent the oil-guiding cotton from moving longitudinally along the atomizing core 100, thereby preventing the oil-guiding cotton from falling off or flipping over.

[0020] Optionally, the number of protruding teeth 32 can be 2-8. If there is only one protruding tooth 32, it can only provide support for one side of the oil-guiding cotton surrounding the porous body 10, and the opposite side of the oil-guiding cotton is at risk of falling off. If there are more than 8 protruding teeth 32, the manufacturing difficulty increases because there are many protruding teeth 32 distributed around the porous body 10, the spacing between two adjacent protruding teeth 32 is small, and the protruding teeth 32 are also thin. When the number of protruding teeth 32 is 2-8, it can both restrict the movement of the oil-guiding cotton and facilitate the manufacturing of the protruding teeth 32. Specifically, the number of protruding teeth 32 can be 2, 3, 4, 5, 6, 7, 8, etc., and is not specifically limited here.

[0021] In one embodiment, the flange 31 is provided with a plurality of air inlet notches 311, such as Figure 1As shown, multiple air inlets 311 are spaced around the outer periphery of the porous body 10. External air can enter the oil-guiding cotton through the air inlets 311, and the oil-guiding cotton is connected to the oil tank, allowing external air to enter the oil tank through the air inlets 311 to balance the gas pressure inside and outside the oil tank, thereby ensuring smooth oil supply to the oil tank.

[0022] Please continue reading. Figure 1 , Figure 2 In one embodiment, the end face of the first end 12 of the porous body 10 is connected to a liquid storage wall 40, which extends away from the second end 13. The projected outer contour of the liquid storage wall 40 on the horizontal plane is located inside the projected outer contour of the limiting member 30 on the horizontal plane. Figure 5 As shown, when the atomizing core 100 is assembled into the air passage tube 313, the outer wall of the liquid storage wall 40 can form a recovery chamber 41 with the inner wall of the air passage tube 313 and the limiting member 30 provided at the first end 12. The recovery chamber 41 can store and recover condensate, splash droplets or excess atomizing liquid. The recovered liquid can be absorbed by the oil guide cotton, thereby preventing condensate from flowing back into the atomizing chamber 11 and causing blockage.

[0023] Optionally, the outer contour of the liquid storage wall 40 projected on the horizontal plane is located inside the outer contour of the porous body 10 projected on the horizontal plane, which increases the distance between the outer wall of the liquid storage wall 40 and the inner wall of the air passage, increases the storage capacity of the recovery chamber 41, can store more condensate, and prevents condensate from flowing back into the atomizing chamber 11 and causing blockage.

[0024] In one embodiment, the cross-sectional area of ​​the atomizing cavity 11 within the range of the second end 13 gradually increases in the direction away from the first end 12, such as... Figure 2 As shown, the aperture of the atomizing chamber 11 gradually increases at the second end 13. The inner wall of the atomizing chamber 11 can guide excess substrate to flow away along the inner wall, preventing excess substrate from accumulating in the atomizing chamber 11 and causing blockage.

[0025] The intersection line between the inner wall of the atomizing cavity 11 within the range of the second end 13 and the plane along the longitudinal direction of the atomizing core 100 can be a curve or an inclined straight line. In one embodiment, the intersection line is an inclined straight line, that is, the inner wall of the atomizing cavity 11 within the range of the second end 13 is inclined, and the angle between the inner wall and the horizontal plane can be 60-85 degrees. Experiments have shown that if the angle is greater than 85 degrees, the inner wall of the atomizing cavity 11 within the range of the second end 13 is almost vertical, the pore size of the atomizing cavity 11 increases only slightly, and the inner wall of the atomizing cavity 11 does not play a role in draining excess matrix; if the angle is less than 60 degrees, the sidewall thickness of the atomizing cavity 11 within the range of the second end 13 is weakened significantly, resulting in insufficient strength of the porous body 10 at one end of the second end 13, making it easy to be crushed during assembly. When the angle between the inner wall of the atomizing chamber 11 within the range of the second end 13 and the horizontal plane is 60-85 degrees, the inner wall can both drain excess matrix to prevent pore blockage and ensure the strength of the porous body 10 at one end of the second end 13. Specifically, the angle between the inner wall of the atomizing chamber 11 within the range of the second end 13 and the horizontal plane can be 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, etc.

[0028] The liquid storage wall 40, the air passage 313, and the limiting member 30 provided at the first end 12 form a recovery chamber 41.
