When the atomizer is working, the microphone senses the user's puffing action, controls the atomizer core to heat the matrix to generate aerosol, and the aerosol flows to one end of the nozzle.

Please refer to Figures 1 and 2. The present application provides an atomizer core 100, which may include a porous body 10 and a heating element 20. The material of the porous body 10 may be porous ceramic, which has good liquid-conducting properties. The porous body 10 can adsorb the substrate, and the heating element 20 heats the substrate to generate an aerosol. An atomizer chamber 11 is provided in the porous body 10, which runs through the porous body 10 longitudinally along the atomizer core 10, and the heating element 20 is installed in the atomizer chamber 11. The porous body 10 has a first end 12 close to the inhalation end of the atomizer 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 a stopper 30, which protrudes from the porous body 10 in the radial direction of the porous body 10. The area between the stopper 30 provided at the first end 12 and the stopper 30 provided at the second end 13 forms an installation position for positioning and installing the oil-conducting cotton.

The atomizer core 100 provided in the present application has limit members 30 at opposite ends of the porous body 10. The limit members 30 protrude from the porous body 10 in the radial direction of the porous body 10, thereby forming enlarged ends at both ends of the porous body 10. The enlarged ends define the installation position of the oil-conducting cotton. The oil-conducting cotton can recycle the condensate, thereby preventing the condensate from flowing back and causing failure of some components in the atomizer.

The position limiting member 30 can be arranged in a variety of ways. In one embodiment, the position limiting member 30 is a flange 31, and the flange 31 circumferentially surrounds the porous body 10, as shown in Figures 1 and 2. The flange 31 is connected to the outer side wall of the porous body 10, and the flanges 31 located at both ends of the porous body 10 and the outer side wall of the porous body 10 define the installation position of the oil-conducting cotton to prevent misalignment when assembling the oil-conducting cotton. After the oil-conducting cotton is assembled, if the oil-conducting cotton moves along the longitudinal direction of the atomizer core 100, the flanges 31 located at both ends provide a supporting reaction force for the oil-conducting cotton to prevent the oil-conducting cotton from moving along the longitudinal direction of the atomizer core 100, thereby preventing the oil-conducting cotton from falling off or flanging.

In another embodiment, the stopper 30 is a convex tooth 32, and a plurality of convex teeth 32 are arranged at intervals on the outer periphery of the porous body 10, as shown in FIG3. Similarly, the convex teeth 32 at both ends of the porous body 10 and the outer side wall of the porous body 10 define the installation position of the oil-conducting cotton, which can prevent the oil-conducting cotton from being misaligned when assembling. After the oil-conducting cotton is assembled, the convex teeth 32 provide a supporting reaction force for the oil-conducting cotton to prevent the oil-conducting cotton from moving longitudinally along the atomizer core 100, thereby preventing the oil-conducting cotton from falling off or flanging.

Optionally, the number of convex teeth 32 is 2-8. If the number of convex teeth 32 is one, the convex tooth 32 can only provide support for one side of the oil-conducting cotton wrapped around the periphery of the porous body 10, and the opposite side of the oil-conducting cotton is at risk of falling off. If the number of convex teeth 32 is greater than 8, since the number of convex teeth 32 distributed on the periphery of the porous body 10 is large, the distance between two adjacent convex teeth 32 is small, and the convex teeth 32 are also thin, which increases the difficulty of manufacturing the convex teeth 32. When the number of convex teeth 32 is 2-8, it can not only limit the movement of the oil-conducting cotton, but also facilitate the manufacture of the convex teeth 32. Specifically, the number of convex teeth 32 can be 2, 3, 4, 5, 6, 7, 8, etc., which is not specifically limited here.

In one embodiment, a plurality of air inlet notches 311 are provided on the flange 31, as shown in FIG1, and the plurality of air inlet notches 311 are spaced around the outer circumference of the porous body 10. External air can enter the oil guide cotton through the air inlet notches 311, and the oil guide cotton is connected to the oil tank, so that external air can enter the oil tank through the air inlet notches 311 to balance the gas pressure inside and outside the oil tank, thereby ensuring smooth oil supply to the oil tank.

Please continue to refer to Figures 1 and 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, and the liquid storage wall 40 extends in a direction away from the second end 13, and the projected outer contour of the liquid storage wall 40 on the horizontal plane is located inside the projected outer contour of the limiter 30 on the horizontal plane. As shown in Figure 5, when the atomizer core 100 is assembled into the airway tube 313, the outer wall of the liquid storage wall 40 can be surrounded by the inner wall of the airway tube 313 and the limiter 30 arranged at the first end 12 to form a recovery chamber 41, which can store and recover condensate, splashing droplets or excess atomized liquid. The recovered liquid can be absorbed by the oil-conducting cotton, thereby preventing the condensate from flowing back into the atomizer chamber 11 and causing blockage.

Optionally, the projected outer contour of the liquid storage wall 40 on the horizontal plane is located inside the projected outer contour of the porous body 10 on the horizontal plane, thereby increasing the distance between the outer wall of the liquid storage wall 40 and the inner wall of the airway tube, increasing the storage capacity of the recovery chamber 41, and storing more condensate, thereby preventing the condensate from flowing back into the atomization chamber 11 and causing pore blockage.

In one embodiment, the cross-sectional area of the atomizing chamber 11 within the second end 13 gradually increases in a direction away from the first end 12, as shown in Figure 2. The aperture of the atomizing chamber 11 gradually expands at the second end 13, and the inner wall of the atomizing chamber 11 can guide the excess matrix to flow along the inner wall, thereby preventing the excess matrix from accumulating in the atomizing chamber 11 and causing pore blockage.

The intersection line between the inner wall of the atomizing chamber 11 within the second end 13 and the plane along the longitudinal direction of the atomizing core 100 may 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 chamber 11 within the second end 13 is inclined, and the angle between the inner wall and the horizontal plane may be 60-85 degrees. The experiment found that if the angle is greater than 85 degrees, the inner wall of the atomizing chamber 11 within the second end 13 is almost vertical, the aperture of the atomizing chamber 11 increases less, and the inner wall of the atomizing chamber 11 does not play a role in draining excess matrix; if the angle is less than 60 degrees, the side wall thickness of the atomizing chamber 11 within the second end 13 is weakened more, resulting in insufficient strength of the porous body 10 at one end of the second end 13, and it is easy to be crushed during assembly. When the angle between the inner wall of the atomizing chamber 11 within the second end 13 and the horizontal plane is 60-85 degrees, the inner wall can not only drain the excess matrix to prevent pore blockage, but also 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 second end 13 and the horizontal plane can be 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, etc.

Please refer to Figures 4 and 5. The present application provides an atomization device 300. The atomization device 300 may include an oil tank 310, the atomization core 100 as described above, an oil tank seal 320, a base 330, a microphone 340, a nozzle 350, a battery 360, a shell 370, and a bottom cover 380. An oil tank seal 320 is provided at one end of the oil tank 310, and the base 330 is connected to the opposite end of the oil tank 310. The microphone 340 is installed in the base 330. The microphone 340 can control the operation of the atomization device 300 by sensing changes in airflow. The oil tank 310, the base 330, and the battery 360 are accommodated in the shell 370. The nozzle 350 is connected to the end of the shell 370 close to the oil tank 310, and the bottom cover 380 is provided at the opposite end of the shell 370.

An airway tube 313 is provided in the oil tank 310, and the atomizer core 100 is installed in the airway tube 313, and the airway tube 313 is connected to the atomizer chamber 11 of the atomizer core 100. The oil tank 310 is provided with an oil storage chamber 314, and the matrix is stored in the oil storage chamber 314. The porous body 10 is wrapped with oil guide cotton 50 between the limiters 30, and the matrix can flow to the porous body 10 through the oil guide cotton 50, and the heating element 20 heats the matrix to generate aerosol.

The liquid storage wall 40, the airway tube 313 and the stopper 30 disposed at the first end 12 are arranged to form a recovery chamber 41. The recovery chamber 41 can store and recover condensed liquid, splashing droplets or excess atomized liquid, and the recovered liquid can be sucked away by the oil-conducting cotton 50, thereby preventing the condensed liquid from flowing back to the atomizing chamber 11 and causing blockage.

The atomizer core 100 provided in the present application has at least the following beneficial effects:

1. The atomizer core 100 provided in the present application has limit members 30 at opposite ends of the porous body 10, thereby forming enlarged ends at both ends of the porous body 10, and the enlarged ends define the installation position of the oil-conducting cotton. The oil-conducting cotton can recycle the condensate, thereby preventing the condensate from flowing back and causing failure of some components in the atomizer.

2. When the number of the convex teeth 32 is 2-8, the movement of the oil-conducting cotton can be restricted and the manufacture of the convex teeth 32 is convenient.

3. The flange 31 is provided with a plurality of air inlet notches 311 , through which external air can enter the oil tank to balance the gas pressure inside and outside the oil tank, thus ensuring smooth oil supply to the oil tank.

4. The end face of the first end portion 12 of the porous body 10 is connected to a liquid storage wall 40. The outer wall of the liquid storage wall 40 can be surrounded by the inner wall of the airway tube 313 and the limiting member 30 arranged at the first end portion 12 to form a recovery chamber 41, which can store and recover condensate, splashing droplets or excess atomized liquid to prevent the condensate from flowing back into the atomization chamber 11 and causing clogging of the holes.

5. The cross-sectional area of the atomizing chamber 11 within the second end 13 gradually increases in the direction away from the first end 12. The inner wall of the atomizing chamber 11 can guide the excess matrix to flow away along the inner wall to prevent the excess matrix from accumulating in the atomizing chamber 11 and causing hole blockage.

6. The angle between the inner wall of the atomizing chamber 11 within the second end 13 and the horizontal plane is 60-85 degrees. The inner wall can not only drain the excess matrix to prevent pore blockage, but also ensure the strength of the porous body 10 at one end of the second end 13.

Please refer to Figures 6 to 8. The present application provides an atomization device 300a. The atomization device 300a may include an oil cup 310a, an atomization core 320a, a nozzle 330a, and a seal 100a. The opposite ends of the seal 100a are respectively connected to the oil cup 310a and the nozzle 330a. The seal 100a is used to seal the oil cup 310a and the nozzle 330a. The atomization core 320a is accommodated in the oil cup 310a, one end of the atomization core 320a is inserted on the seal 100a, and the atomization core 320a is connected to the nozzle 330a. The oil cup 310a stores a matrix, which can flow to the atomization core 320a, and the atomization core 320a heats the matrix to generate an aerosol.

The atomizing device 300a may further include a sealing seat 340a, a microphone 350a, a battery 360a, a bottom cover 370a and a housing 380a. The bottom cover 370a is connected to the end of the housing 380a away from the suction nozzle 330a, the battery 360a, the sealing seat 340a, the oil cup 310a and the sealing member 100a are sequentially assembled on the bottom cover 370a, and one end of the atomizing core 320a is mounted on the sealing seat 340a. The microphone 350a is mounted in the sealing seat 340a, and the microphone 350a controls the working state of the atomizing device 300a by sensing the suction action at one end of the suction nozzle 330a. When inhaling, the microphone 350a controls the atomizer core 320a to be connected with the battery 360a, and the atomizer core 320a heats the substrate to generate aerosol; when inhalation stops, the microphone 350a controls the atomizer core 320a to be disconnected from the battery 360a, and the atomizer core 320a stops heating.

The housing 380a may be made of metal or plastic, and the suction nozzle 330a and the oil cup 310a may be made of plastic. The sealing member 100a and the sealing seat 340a may be silicone, which has a certain elasticity. When the sealing member 100a and the sealing seat 340a are assembled into the atomizing device 300a, the sealing member 100a and the sealing seat 340a are squeezed and deformed. The sealing member 100a, the oil cup 310a and the suction nozzle 330a are interference-fitted to seal the oil cup 310a and the suction nozzle 330a. The sealing seat 340a and the oil cup 310a are interference-fitted to seal the end of the oil cup 310a away from the suction nozzle, so that the atomizing device 300a has good air tightness and can increase the negative pressure during suction.

The atomizing core 320a may include an atomizing tube 321a, an oil-conducting cotton 322a, and a heating element 323a. The atomizing tube 321a may be made of metal, and the oil-conducting cotton 322a may be made of plant fiber. One end of the atomizing tube 321a is inserted on the sealing element 100a, the atomizing tube 321a is connected to the suction nozzle 330a, and the opposite end of the atomizing tube 321a is mounted on the sealing seat 340a. The oil-conducting cotton 322a is wrapped around the outer periphery of the heating element 323a, and the oil-conducting cotton 322a is accommodated in the atomizing tube 321a. An oil hole is provided on the side wall of the atomizing tube 321a, and the matrix in the oil cup 310a can enter the oil-conducting cotton 322a through the oil hole. The heating element 323a heats the matrix adsorbed by the oil-conducting cotton 322a to generate an aerosol, and the aerosol reaches the suction nozzle 330a through the atomizing tube 321a.

As the aerosol flows away from the atomization core 320a toward the side of the suction nozzle 330a, the temperature of the aerosol decreases, and part of the aerosol condenses and liquefies to form condensate. If the condensate flows back along the airway, it may cause some components in the atomization device 300a to fail. At the same time, the condensate mixes with the aerosol, which will affect the taste of the aerosol.

In order to prevent the condensate from flowing back along the airway, the present application provides a seal 100a, please refer to FIG. 9, the seal 100a is arranged between the oil cup 310a and the suction nozzle 330a, and the seal 100a is used to seal the oil cup. A plurality of convex columns 110a are arranged at intervals at one end of the seal 100a close to the suction nozzle 330a, and the convex columns 110a extend toward the end where the suction nozzle 330a is located, and each convex column 110a can be surrounded by the adjacent convex columns 110a to form a condensate adsorption gap 111a for adsorbing the condensate, thereby preventing the condensate from flowing back and causing some components in the atomization device 300a to fail.

Condensate may form and accumulate on the inner wall of the airway of the atomizing device 300a. As the aerosol moves away from the atomizing core 320a toward the side of the suction nozzle 330a, the temperature of the aerosol decreases. The closer to the suction nozzle 330a, the higher the possibility of condensate formation. The sealing member 100a is arranged between the oil cup 310a and the suction nozzle 330a, and the protruding column 110a extends toward the end where the suction nozzle 330a is located, so that the condensate formed at the suction nozzle 330a can be adsorbed by the condensate adsorption gap 111a. When the atomizing device 300a is not in use, the condensate at the condensate adsorption gap 111a can evaporate naturally, so that the condensate is not easy to flow down along the airway and accumulate inside the atomizing device 300a, thereby eliminating the failure of some components in the atomizing device 300a, such as the microphone 350a, due to the accumulation of condensate.

The sealing member 100a is provided with an air hole 140a, as shown in FIG9 , and the atomizing tube 321a is inserted into the air hole 140a. In one embodiment, a plurality of protrusions 110a are arranged around the circumference of the air hole 140a, thereby forming a plurality of condensate adsorption gaps 111a arranged in an annular manner. The annularly arranged condensate adsorption gaps 111a allow the condensate adsorption gaps 111a to be distributed around the periphery of the aerosol flowing through, thereby increasing the contact area between the condensate adsorption gaps 111a and the aerosol flowing through, thereby better adsorbing the condensate.

In some embodiments, the spacing between two adjacent protrusions 110a is 0.4 mm to 0.5 mm. Experiments have found that if the spacing between two adjacent protrusions 110a is greater than 0.5 mm, the spacing between two adjacent protrusions 110a is large, it is difficult to produce capillary action on the condensate, and the condensate adsorption gap 111a cannot adsorb the condensate. If the spacing between two adjacent protrusions 110a is less than 0.4 mm, the processing difficulty of the protrusions 110a will increase, and the processing cost of the seal 100a will increase. When the spacing between two adjacent protrusions 110a is in the range of 0.4 mm to 0.5 mm, the condensate can be better adsorbed and the processing of the protrusions 110a is convenient. Specifically, the spacing between two adjacent protrusions 110a can be 0.4 mm, 0.42 mm, 0.45 mm, 0.48 mm, 0.5 mm, etc., which are not specifically limited here.

If the extension height of the protrusion 110a toward the suction nozzle 330a is too long, the protrusion 110a is slender, and the end of the slender protrusion 110a close to the suction nozzle 330a is a free end. The protrusion 110a made of silicone material is relatively soft, and the free end of the protrusion 110a is easy to bend, causing the ends of two adjacent protrusions 110a to fit together, reducing the space between the two protrusions 110a. The condensate cannot be adsorbed if the height of the protrusion 110a is insufficient. If the height of the protrusion 110a is insufficient, the adsorption of the condensate in the aerosol will not be sufficient, and some of the condensate will still be mixed into the aerosol and affect the taste of the aerosol. In some embodiments, the height of the protrusion 110a is 4.0 mm to 5.0 mm. When the height of the protrusion 110a is within this range, the condensate can be fully adsorbed, and the free end of the protrusion 110a will not bend and fail to adsorb the condensate. Specifically, the height of the protrusion 110a can be 4.0 mm, 4.2 mm, 4.5 mm, 4.8 mm, 5.0 mm, and so on.

Optionally, multiple convex pillars 110a are arranged in parallel with each other, and the sizes of each convex pillar 110a are equal. The number of convex pillars 110a is preferably 8 to 16, and the multiple convex pillars 110a are distributed at equal intervals to facilitate the processing of the convex pillars 110a. Specifically, the number of convex pillars 110a can be 8, 10, 12, 14, or 16.

When the condensate adsorption gap 111a adsorbs a large amount of condensate, the condensate may overflow and spread to the periphery of the seal 100a. In order to prevent the condensate from overflowing and spreading, in one embodiment, a baffle 120a is connected to one end of the seal 100a close to the suction nozzle 330a. As shown in FIG10 , the baffle 120a is arranged around the periphery of the plurality of convex columns 110a. The baffle 120a can limit the condensate from overflowing to the periphery of the seal 100a. The convex columns 110a can be connected to the inner wall of the baffle 120a, so that the baffle 120a can be processed integrally with the convex columns 110a. The baffle 120a connects the roots of the plurality of convex columns 110a as one, which can reduce the length of the free end of the convex column 110a and prevent the convex column 110a from bending.

In some embodiments, the ratio of the height of the baffle 120a to the height of the convex column 110a is 0.4 to 0.6. The recovered condensate accumulates at the bottom of the condensate adsorption gap 111a under the action of gravity. It is only necessary to set the baffle 120a within the above-mentioned height range at the root of the convex column 110a to prevent the condensate from overflowing to the periphery of the sealing member 100a, so as to save the amount of material. Specifically, the ratio of the height of the baffle 120a to the height of the convex column 110a can be 0.4, 0.45, 0.5, 0.55, 0.6, etc.

In order to facilitate the remote oil filling of the atomizing device 300a, in one embodiment, an oil filling hole 130a is provided on the sealing member 100a, as shown in FIG10. Correspondingly, a sealing column 331a is provided on the suction nozzle 330a, as shown in FIG8. When the suction nozzle 330a is connected to the sealing member 100a, the sealing column 331a is inserted into the oil filling hole 130a. When filling oil, the matrix can be added into the oil cup 310a through the oil filling hole 130a; after the oil filling is completed, the sealing column 331a is inserted into the oil filling hole 130a to seal the oil filling hole 130a. When the sealing column 331a is pressed into the oil filling hole 130a, the sealing column 331a compresses the air in the oil cup 310a, increases the air pressure inside the oil cup 310a, and there is a risk that the compressed air pushes the matrix in the oil cup 310a to leak outward.

In order to prevent matrix leakage caused by the sealing column 331a being pressed into the oil filling hole 130a, in one embodiment, a sealing rib 131a is provided on the inner wall of the oil filling hole 130a, as shown in Figures 9 and 10. The sealing rib 131a is arranged in an annular shape and extends into the oil filling hole 130a. When the sealing column 331a is pressed into the oil filling hole 130a, the outer wall of the sealing column 331a only contacts the sealing rib 131a, forming a partial annular surface contact, reducing the contact area between the sealing column 331a and the inner wall of the oil filling hole 130a, and reducing the friction between the sealing column 331a and the inner wall of the oil filling hole 130a. Compared with the direct contact between the sealing column 331a and the inner wall of the oil filling hole 130a, part of the air inside the oil cup 310a can be released through the oil filling hole 130a, thereby reducing the air pressure inside the oil cup 310a, and preventing the sealing column 331a from causing matrix leakage when it is pressed into the oil filling hole 130a. After the oil filling is completed, the suction nozzle 330a is connected to the sealing member 100a, and the sealing column 331a set on the suction nozzle 330a is inserted into the oil filling hole 130a. The sealing column 331a and the sealing rib 131a cooperate to seal the oil cup 310a.

In one embodiment, two baffles 120a are provided, and the two baffles 120a are arranged opposite to each other. Accordingly, the number of oil injection holes 130a is two, and the oil injection holes 130a and the baffles 120a are arranged at intervals around the outer periphery of the plurality of protrusions 110a. When the suction nozzle 330a is connected to the sealing member 100a, the sealing column 331a is inserted into the oil injection hole 130a located between the two baffles 120a, and the sealing member 331a is inserted into the sealing member 100a. The side wall of the sealing column 331a can be enclosed with the baffle 120a to prevent the condensed liquid from overflowing to the outer periphery of the sealing element 100a.

The seal 100a provided in the present application has at least the following beneficial effects:

1. A plurality of convex columns 110a are provided at intervals at one end of the sealing member 100a close to the nozzle 330a. Each convex column 110a can be surrounded by the adjacent convex columns 110a to form a condensate adsorption gap 111a. The condensate adsorption gap 111a can collect and lock the condensate, thereby preventing the condensate from flowing back along the airway, and improving the taste of the aerosol.

2. The plurality of convex columns 110a are arranged around the circumference of the air hole 140a, thereby increasing the contact area between the condensate adsorption gap 111a and the aerosol flowing therethrough, and can better adsorb the condensate.

3. The distance between two adjacent protrusions 110a is 0.4 mm to 0.5 mm, which can not only better absorb the condensate but also facilitate the processing of the protrusions 110a.

4. The height of the protrusion 110a is 4.0 mm to 5.0 mm, which can fully absorb the condensate, and the free end of the protrusion 110a will not bend and fail to absorb the condensate.

5. The end of the sealing member 100a close to the suction nozzle 330a is connected with a baffle 120a. The baffle 120a can not only limit the condensate from overflowing to the periphery of the sealing member 100a, but also reduce the length of the free end of the protruding column 110a to prevent the protruding column 110a from bending.

6. A sealing rib 131a is provided on the inner wall of the oil filling hole 130a, which reduces the contact area between the sealing column 331a and the inner wall of the oil filling hole 130a, and can reduce the friction between the sealing column 331a and the inner wall of the oil filling hole 130a, thereby preventing the sealing column 331a from causing matrix leakage when it is pressed into the oil filling hole 130a.
