[0045] Currently, there is an electronic cigarette on the market with an inseparable atomizer core, in which the atomizer core is directly clamped at the opening of the oil cup, and the clamping structure of the two is an inverted buckle design, so that the atomizer core is fixed in the oil cup and cannot be disassembled. The atomizer core includes ceramics and a heating element, the ceramics are used to absorb the smoke oil, and the heating element is arranged on the lower surface of the ceramics and is used to heat the smoke oil. The atomizer core includes ceramics and a heating element, the ceramics are used to absorb the smoke oil, and the heating element is arranged on the lower surface of the ceramics and is used to heat the smoke oil.

[0046] The above-mentioned related technologies have the following defects:

[0047] 1. The atomizer core is fixed in the oil cup and cannot be disassembled. The atomizer core cannot be recycled, which is very wasteful. It basically adopts a one-spring-one-core structure. The production efficiency of this product is not high, and it will indirectly increase sales costs, and there is no competitive advantage in the market;

[0048] 2. Since the atomizer core is fixed in the oil cup and cannot be removed, the e-liquid is in contact with the atomizer core for a long time. The outside air can enter the oil storage tank of the oil cup through the atomizer core, which can easily cause the e-liquid to deteriorate. The atomizer core is also immersed in the e-liquid for a long time, resulting in a reduction in the service life of the atomizer core.

[0049] In order to solve the above objective technical problems, the present application provides an aerosol generating device with a sealing function. Please refer to Figure 1-Figure 6 , the aerosol generating device with sealing function provided in the embodiment of the present application is now described.

[0050] The present application provides an aerosol generating device with a sealing function. Figure 1 and Figure 2, including an oil cup 101, an atomizer core 102 and a connector 103. The oil cup 101 is flat in design. An air outlet pipe 11 and a plurality of oil storage bins 12 are arranged in the oil cup 101. The air outlet pipe 11 is vertically arranged along the central axis of the oil cup 101. The oil storage bins 12 are arranged around the air outlet pipe 11. A mounting port is arranged at the bottom of the oil cup 101. The top of the atomizer core 102 is detachably sealed and installed at the mounting port. The connector 103 is connected between the bottom of the air outlet pipe 11 and the air outlet of the atomizer core 102. The connector 103 is also connected between the bottom of the oil storage bin 12 and the smoke oil inlet of the atomizer core 102.

[0051] See also Figures 1 to 3 The atomizer core 102 includes a mounting seat 21, a ceramic heating component 22, a sealing sleeve 23 and an oil inlet cover 24. The mounting seat 21 and the oil inlet cover 24 are both made of hard plastic. The mounting seat 21 and the oil inlet cover 24 can be detachably assembled to clamp the ceramic heating component 22. The sealing sleeve 23 covers the top of the ceramic heating component 22. The surrounding side of the sealing sleeve 23 is provided with a first exhaust notch 232. The top of the sealing sleeve 23 is provided with a hole 231 connected to the inside of the ceramic heating component 22. The sealing sleeve 23 is installed at the bottom of the oil inlet cover 24. The bottom of the oil inlet cover 24 is provided with a second exhaust notch 241 arranged corresponding to the first exhaust notch 232. The top of the oil inlet cover 24 is protruding with a plurality of smoke oil inlet pipes 242 communicating with the holes 231. The smoke oil inlet pipe 242 is the smoke oil inlet. The surrounding side wall of the mounting seat 21 and the inner wall of the oil cup 101 are detachably sealed and connected. The bottom of the mounting seat 21 is provided with a smoking port for connecting to a cigarette rod.

[0052] The first exhaust notch 232 and the second exhaust notch 241 are both isosceles trapezoidal in design, and the first exhaust notch 232 and the second exhaust notch 241 are designed to be small at the top and large at the bottom. The sealing sleeve 23 is designed as a rectangular parallelepiped as a whole before the first exhaust notch 232 is formed.

[0053] Two oil inlet pipes 242 are provided and are symmetrically designed. The cross-sectional outer contour of the atomizer core 102 is elliptical, and the two oil inlet pipes 242 are located on the long axis of the ellipse. In other embodiments, the oil inlet pipes 242 can also be one, three, four, five or more. Of course, all the oil inlet pipes 242 can be evenly and symmetrically spaced around the central axis of the oil inlet cover 24. As the number of oil inlet pipes 242 increases, the number of oil storage bins 12 corresponding to the oil cup 101 also needs to increase.

[0054] A circle of grooves is provided in the middle of the peripheral side wall of the mounting seat 21, and an O-ring 25 is clamped in the groove, and the O-ring 25 is pressed against the inner peripheral wall of the oil cup 101. The O-ring 25 can improve the sealing between the mounting seat 21 and the oil cup 101, thereby effectively avoiding oil and smoke leakage, and the product quality is higher.

[0055] Side clamping plates 211 are respectively arranged on both sides of the top of the mounting seat 21. The two side clamping plates 211 cooperate to clamp both sides of the bottom of the oil inlet cover 24. The side clamping plates 211 are located above the O-ring 25. The two side clamping plates 211 have the function of limiting and clamping the bottom of the oil inlet cover 24, so as to make the oil inlet cover 24 and the mounting seat 21 more firmly connected.

[0056] The side clamping plate 211 is provided with a clamping hole 212, and clamping blocks 243 are respectively provided on both sides of the bottom of the oil inlet cover 24. The bottom outer side of the clamping block 243 is provided with a guiding inclined surface 2431. The clamping block 243 and the clamping hole 212 on the side clamping plate 211 cooperate with each other to achieve a firm connection between the oil inlet cover 24 and the mounting seat 21. In addition, the above structure is a detachable design, which is convenient for removing the ceramic heating component 22 for cleaning and maintenance. The design of the guiding inclined surface 2431 facilitates the rapid insertion of the bottom of the oil inlet cover 24 between the two side clamping plates 211.

[0057] A reinforcing rib 244 is provided between the top of the clamping block 243 and the bottom outer side surface of the oil inlet cover 24 , and the reinforcing rib 244 can make the connection between the clamping block 243 and the oil inlet cover 24 more firm, and the clamping block 243 is not easy to fall off due to frequent disassembly.

[0058] The two outer sides of the sealing sleeve 23 are provided with sealing ridges 233 that abut against the bottom inner side of the oil inlet cover 24. The sealing ridges 233 can significantly improve the sealing between the sealing sleeve 23 and the oil inlet cover 24, and effectively prevent the leakage of smoke oil and smoke.

[0059] The ceramic heating component 22 includes a ceramic heating core 221, a positive electrode 222, a negative electrode 223 and a polymer oil-absorbing cotton block 224. The positive electrode 222 and the negative electrode 223 are both connected to the bottom of the ceramic heating core 221. The positive electrode 222 and the negative electrode 223 both pass through the polymer oil-absorbing cotton block 224. The polymer oil-absorbing cotton block 224 is sandwiched between the bottom of the ceramic heating core 221 and the positive electrode 222 and the negative electrode 223. The polymer oil-absorbing cotton block 224 is arranged horizontally.

[0060] The polymer oil-absorbing cotton block 224 has a good absorption effect on the smoke oil, which can improve the taste of the electronic cigarette to a certain extent. The ceramic heating component 22 designed above has a simple structure, stable operation, and is easy to install and disassemble.

[0061] A sealing plug 26 is detachably inserted at the smoking port, and the sealing plug 26 includes a sealing rod 261 and a sealing disk 262. The sealing rod 261 is vertically connected to the center position of the upper surface of the sealing disk 262. When the atomizer core 102 is not connected to the cigarette rod, the sealing plug 26 can block the smoking port to effectively prevent the smoking port from being contaminated. The sealing plug 26 can be pulled out when smoking.

[0062] Two recessed grooves are provided at the bottom of the mounting seat 21, and magnets 27 for magnetically fixing the cigarette rod are mounted in the recessed grooves. The two magnets 27 are located on both sides of the sealing plug 26. The magnets 27 and the recessed grooves are both cylindrical in shape. The design of the magnets 27 can be used to magnetically fix the cigarette rod, which is conducive to the firmness of the connection between the cigarette rod and the mounting seat 21.

[0063] A circular annular groove 213 is provided on the peripheral side wall of the mounting seat 21 located outside the oil cup 101. In this embodiment, there are three circular annular grooves 213, which are evenly spaced up and down. The circular grooves 213 are used to increase the friction and touch feel of the surface of the mounting seat 21.

[0064] See also Figure 4 and Figure 5 The connector 103 includes a sealing silicone part 31 and a plurality of hard tubes 32. The sealing silicone part 31 is generally made of soft silicone, and the hard tube 32 can be made of ordinary steel pipe, stainless steel pipe, aluminum alloy steel pipe or other hard materials.

[0065] Combination Figure 1-Figure 5 A vertically arranged air outlet hole 311 is provided in the middle of the sealing silicone part 31, and the air outlet hole 311 is connected to the air outlet pipe 11 of the oil cup 101. An exhaust groove 312 connected to the bottom of the air outlet hole 311 is provided at the bottom of the sealing silicone part 31, and the exhaust groove 312 is connected to the air outlet of the atomizer core 102. A plurality of vertically arranged mounting holes 313 are also provided on the sealing silicone part 31, and the plurality of mounting holes 313 are arranged at intervals around the circumference of the air outlet hole 311. The hard tube 32 is installed in the mounting hole 313, and the bottom of the hard tube 32 is connected to the smoke oil inlet of the atomizer core 102, and the top of the hard tube 32 is connected to the oil storage bin 12 of the oil cup 101.

[0066] Two hard tubes 32 are provided and are located on both sides of the air outlet 311, respectively. The two mounting holes 313 and the air outlet 311 are located on the same straight line. In other embodiments, the hard tubes 32 can also be three, four, five or more. Of course, all the mounting holes 313 can be designed to be evenly and symmetrically spaced around the circumference of the air outlet 311. As the number of installations increases, the number of hard tubes 32 also needs to be increased, and the number of oil storage bins 12 corresponding to the oil cup 101 also needs to be increased.

[0067] The horizontal cross-section outer contour of the sealing silicone part 31 is an ellipse, the vertical cross-section of the exhaust groove 312 is a rectangular design, and the length direction of the exhaust groove 312 is parallel to the short axis direction of the ellipse. The sealing silicone part 31 and the exhaust groove 312 designed as above are more conducive to quickly sending out the smoke discharged from the air outlet of the atomizer core 102, and smoke blocking is not easy to occur.

[0068] The width of the exhaust groove 312 is greater than the diameter of the air outlet hole 311. For example, in this embodiment, the width of the exhaust groove 312 is between 1.1 and 1.2 times the diameter of the air outlet hole 311. Under the premise of not affecting the structural strength of the entire sealing silicone part 31, it is ensured that as long as the smoke enters the exhaust groove 312, it can be discharged through the air outlet hole 311.

[0069] The diameter of the mounting hole 313 is smaller than the outer diameter of the hard tube 32. For example, in this embodiment, the diameter of the mounting hole 313 is 0.9-9.95 times the outer diameter of the hard tube 32. Because the sealing silicone portion 31 is relatively soft, the hard tube 32 can enlarge the mounting hole 313, thereby achieving a firm connection between the hard tube 32 and the sealing silicone portion 31, and the sealing silicone portion 31 will almost completely fit and wrap the hard tube 32, ensuring that the sealing between the hard tube 32 and the mounting hole 313 is very good and oil leakage is not likely to occur.

[0070] A sealing bottom plate 314 integrally formed with the sealing silicone portion 31 is provided at the bottom of the mounting hole 313. When the atomizer core 102 is not assembled to the oil cup 101, the sealing bottom plate 314 prevents the smoke oil from flowing out of the oil storage bin 12 to achieve the purpose of sealing the smoke oil. When the atomizer core 102 is assembled to the oil cup 101, the sealing bottom plate 314 is broken by the atomizer core 102 to achieve the purpose of smoke oil communication between the oil cup 101 and the atomizer core 102.

[0071] The sealing bottom plate 314 is provided with a breakable structure for the oil inlet pipe to break. The material of the sealing bottom plate 314 is also soft. When the oil inlet pipe at the top of the atomizer core 102 breaks the sealing bottom plate 314, a part of the sealing bottom plate 314 will be sandwiched between the oil inlet pipe and the hard tube 32, thereby greatly improving the connection sealing between the atomizer core 102 and the hard tube 32, and effectively improving the oil or air leakage phenomenon.

[0072] Reference Figure 5 and Figure 6 The breakable structure includes a first cross pre-breaking groove 3141 provided on the upper surface of the sealing bottom plate 314 and a second cross pre-breaking groove 3142 provided on the lower surface of the sealing bottom plate 314. The design of the first cross pre-breaking groove 3141 and the second cross pre-breaking groove 3142 can facilitate the smoke oil inlet pipe at the top of the atomizer core 102 to break the sealing bottom plate 314 (see Figure 3 ), so that part of the sealing bottom plate 314 is sandwiched between the smoke oil inlet pipe and the hard tube 32 to enhance the sealing performance.

[0073] A retaining ring 315 is provided at the top opening of the mounting hole 313 to block the top of the rigid tube 32. The design of the retaining ring 315 can limit the rigid tube 32 to a certain extent, effectively preventing the rigid tube 32 from arbitrarily detaching from the mounting hole 313, greatly improving the connection firmness between the rigid tube 32 and the sealing silicone part 31, and making the structure more stable.

[0074] The outer wall of the sealing silicone part 31 is protruded with two circles of outer sealing strips 316 that abut against the inner wall of the oil cup 101. The outer sealing strip 316 is located above the exhaust groove 312. The cross-section of the outer sealing strip 316 is a right-angled trapezoid, and the outer side of the upper surface of the outer sealing strip 316 is designed to be an inclined surface so that the sealing silicone part 31 can be quickly inserted into the interior of the oil cup 101.

[0075] The design of the outer sealing strip 316 can improve the connection sealing between the outer peripheral wall of the sealing silicone part 31 and the inner peripheral wall of the oil cup 101, and effectively improve the phenomenon of oil leakage or air leakage.

[0076] In other embodiments, the outer sealing strip 316 may be designed to be one circle, three circles, four circles, or even more circles. When there are multiple outer sealing strips 316 , adjacent outer sealing strips 316 are arranged with intervals in the upper and lower parts.

[0077] The inner peripheral wall of the air outlet hole 311 is protruded with two circles of inner sealing strips 317 that abut against the outer peripheral wall of the air outlet pipe 11 of the oil cup 101. The cross section of the inner sealing strip 317 is semi-elliptical, and the outer side of the inner surface of the inner sealing strip 317 is designed as an arc surface, so that the air outlet pipe 11 of the oil cup 101 can be quickly inserted into the interior of the air outlet hole 311.

[0078] The design of the inner sealing strip 317 can improve the connection sealing between the sealing silicone portion 31 and the air outlet pipe 11 of the oil cup 101, and effectively improve the oil or air leakage phenomenon.

[0079] In other embodiments, the inner sealing strip 317 may also be designed to be one circle, three circles, four circles, or even more circles. When there are multiple inner sealing strips 317 , adjacent inner sealing strips 317 are arranged with intervals in the upper and lower parts.

[0080] In summary, the aerosol generating device with sealing function provided by the present application has the following advantages compared with the prior art:

[0081] 1. By adding the connecting piece 103, the atomizer core 102 and the oil cup 101 can be disassembled, the atomizer core 102 can be recycled, and it is not easy to cause waste. A one-shell multi-core structure can be realized. This product has higher production efficiency, and can indirectly reduce sales costs, and has more competitive advantages in the market.

[0082] 2. The design of the sealing bottom plate 314 can seal the e-liquid in the oil storage bin 12 of the oil cup 101, so that the e-liquid will not leak out even if the atomizer core 102 is disassembled. Moreover, when the oil cup 101 and the atomizer core 102 are assembled, the sealing bottom plate 314 can be pierced by the atomizer core 102, so that the e-liquid in the oil storage bin 12 of the oil cup 101 can flow into the interior of the atomizer core 102 along the hard tube 32, thereby realizing detachable assembly between the oil cup 101 and the atomizer core 102.

[0083] 3. Since the sealing bottom plate 314 has a sealing effect on the smoke oil in the oil storage bin 12, the smoke oil will not be in contact with the atomizer core 102 for a long time, and the outside air is not easy to enter the oil storage bin 12 of the oil cup 101 through the atomizer core, which is not easy to cause the smoke oil to deteriorate, and the atomizer core 102 will not be immersed in the smoke oil for a long time, thereby extending the service life of the atomizer core 102.

[0084] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
