[0024] As shown in the drawings, Figures 1 to 4 The utility model discloses an oil leakage prevention structure of electronic cigarette cartridge external oil bottle, which comprises an oil bottle 1, an oil cup 2, an oil cup upper gel 3, a suction nozzle 4, oil storage cotton 5 and an atomizing core assembly 6. The oil cup 2 is internally provided with an atomizing chamber 21, a buffer oil storage 22, an oil passing passage 23 and an exhaust passage 24. The atomizing core assembly 6 and the oil storage cotton 5 are installed in the atomizing chamber 21, and the oil storage cotton 5 surrounds the outside of the atomizing core assembly 6. The atomizing chamber 21 and the buffer oil storage 22 are communicated through the oil passing passage 23. The oil cup upper gel 3 is connected above the oil cup 2, and is internally provided with an airflow passage 31. The airflow passage 31 communicates the buffer oil storage 22 and the exhaust passage 24. The oil bottle 1 is provided with an oil outlet hole 11. The oil outlet hole 11 is connected into the atomizing chamber 21 after penetrating through the oil cup upper gel 3. The suction nozzle 4 is connected to the atomizing core assembly 6 after penetrating through the oil cup upper gel 3.

[0025] The suction nozzle 4 is made of plastic material and is designed with a smoke suction channel. The channel column is in interference seal with the oil cup upper glue body 3 and is in communication with the atomization core assembly 6, so as to realize the circulation of smoke. The oil bottle 1 is made of PCTG plastic material and is corrosion resistant. The oil bottle 1 is designed with an oil outlet hole 11 for connecting to the inside of the atomization chamber 21 of the oil cup 2. The oil bottle 1 has two oil outlet holes 11 which are uniformly connected to the atomization chamber 21. The oil cup upper glue body 3 is made of food-grade silica gel material and is designed with an air flow channel 31 and an oil inlet hole. The oil cup upper glue body 3 is assembled on the oil cup upper cover 7 and is in interference seal with the oil cup upper cover 7, the oil cup 2, the oil bottle 1 and the suction nozzle 4. The oil cup 2 is made of PCTG plastic material and is corrosion resistant. The oil cup 2 is designed with a chamber atomization hole 26, two chamber oil inlet holes 25, two oil storage cotton oil suction ports 51, two oil storage warehouses 22, an oil passage hole 27, an oil passage groove 28, an exhaust passage 24 and a buffer oil warehouse 22. The oil cup 2 is in interference seal with the oil cup upper glue body 3, is fixed with the oil cup upper cover 7 and is fixed with the oil cup bottom cover 8. The oil storage cotton 5 is made of PA+PET material and has the functions of smoke oil adsorption and oil guiding. The oil storage cotton 5 is assembled on the atomization core assembly 6 and the oil cup 2 and is in interference with the oil cup 2, so that the smoke flow can only pass through the inside of the oil storage cotton 5.

[0026] The structure is designed with two oil inlet paths of the cartridge and an independent oil cup 2 buffer oil warehouse 22. (1) When the user uses it normally, the oil storage cotton 5 normally absorbs oil to supply oil to the atomization core assembly 6, and the excess smoke oil flows to the buffer oil warehouse 22 of the oil bottle 1. (2) In the high-altitude negative pressure and high-temperature environment, because the oil cup upper glue body 3 is provided with the air flow channel 31, most of the smoke oil squeezed out of the oil bottle 1 will first flow to the buffer oil warehouse 22 of the oil cup 2. When the user uses it again, the smoke oil in the buffer oil warehouse 22 will be re-absorbed by the oil storage cotton 5 and supplied to the atomization core assembly 6 under the driving of the exhaust passage 24, the air flow channel 31 and the smoke flow, so as to avoid the problem that the smoke oil directly leaks to the outside of the product in the high-altitude negative pressure and high-temperature environment.

[0027] The oil bottle 1 is provided with an oil outlet column 12. The oil outlet of the oil bottle 1 is arranged on the oil outlet column 12. The oil outlet column 12 is inserted into the atomization chamber 21. The oil outlet of the oil bottle 1 is located at the top of the atomization chamber 21 and is in butt joint with the oil storage cotton 5. The oil outlet column 12 is a column structure protruding downward from the bottom of the oil bottle 1, that is, a smoke oil drainage passage and a structural part assembled with the oil cup upper cover 7, the oil cup upper glue body 3 and the oil cup 2. The oil outlet column 12 is in interference seal with the oil cup upper glue body 3. The oil outlet column 12 is directly inserted into the atomization chamber 21, so as to avoid that the smoke oil in the oil bottle 1 directly flows into the buffer oil warehouse 22. The smoke oil of the oil outlet column 12 finally enters the oil storage cotton suction port 51 in the atomization chamber 21 through the oil outlet of the oil bottle 1 and is injected into the oil storage cotton 5.

[0028] The oil cup upper colloid 3 is also provided with a colloid oil inlet hole 32, and the top of the atomization chamber 21 is provided with a chamber oil inlet hole 25. The colloid oil inlet hole 32 is aligned with the chamber oil inlet hole 25, and the oil bottle oil outlet hole 11 passes through the colloid oil inlet hole 32 and the chamber oil inlet hole 25. The colloid oil inlet hole 32 is in interference fit with the oil bottle oil outlet hole 11. The oil cup upper colloid 3 is also provided with two colloid oil inlet holes 32 corresponding to the two chamber oil inlet holes 25 on the atomization chamber 21. The oil outlet columns 12 of the two oil bottles 1 are respectively inserted into one of the colloid oil inlet holes 32 and the chamber oil inlet holes 25, so that the oil bottle oil outlet hole 11 is connected to the atomization chamber 21 after passing through the colloid oil inlet hole 32 and the chamber oil inlet hole 25.

[0029] The oil cup upper colloid 3 is also provided with a colloid oil inlet hole 32, and the top of the atomization chamber 21 is provided with a chamber oil inlet hole 25. The colloid oil inlet hole 32 is aligned with the chamber oil inlet hole 25, and the oil bottle oil outlet hole 11 passes through the colloid oil inlet hole 32 and the chamber oil inlet hole 25. The colloid oil inlet hole 32 is in interference fit with the oil bottle oil outlet hole 11. The oil cup upper colloid 3 is also provided with two colloid oil inlet holes 32 corresponding to the two chamber oil inlet holes 25 on the atomization chamber 21. The oil outlet columns 12 of the two oil bottles 1 are respectively inserted into one of the colloid oil inlet holes 32 and the chamber oil inlet holes 25, so that the oil bottle oil outlet hole 11 is connected to the atomization chamber 21 after passing through the colloid oil inlet hole 32 and the chamber oil inlet hole 25.

[0030] The airflow passage 31 is staggered with the colloid oil inlet hole 32 and the colloid atomization hole 33.

The airflow through hole 34 at one end of the airflow passage 31 is connected to the top of the exhaust passage 24, and the bottom of the exhaust passage 24 extends outside the oil cup 2. The airflow through hole 35 at the other end of the airflow passage 31 is connected to the buffer oil reservoir 22. The airflow passage 31, the oil inlet path, and the atomization path are three separate paths that respectively serve to exhaust the inside of the oil cup 2, introduce oil, and guide smoke. Therefore, the airflow passage 31 is staggered with the colloid oil inlet hole 32 and the colloid atomization hole 33. When exhausting, the excess gas in the buffer oil reservoir 22 enters one end of the airflow passage 31, flows into the exhaust passage 24 from the other end along the airflow passage 31, and is exhausted to the outside of the oil cup 2 along the exhaust passage 24. When the user inhales again, the gas outside the oil cup 2 enters the buffer oil reservoir 22 along the exhaust passage 24 and the airflow passage 31 to increase the air pressure in the buffer oil reservoir 22 and squeeze the oil in the buffer oil reservoir 22 into the oil storage cotton 5.

[0031] The oil leakage prevention structure of the electronic cigarette cartridge external oil bottle 1 further comprises an oil cup upper cover 7 connected with the oil cup 2, the oil cup upper cover 7 being sealingly connected to the top of the oil cup upper rubber body 3, the oil cup upper cover 7 being provided with an upper cover oil inlet hole 71 and an upper cover atomization hole 72, the upper cover oil inlet hole 71 being aligned with the rubber body oil inlet hole 32, the upper cover atomization hole 72 being aligned with the rubber body atomization hole 33, and the oil cup upper cover 7 covering the airflow channel 31. The oil cup upper cover 7 is made of plastic material, is provided with a clamping position to be fixed to the top of the oil cup 2, and is in interference sealing with the oil cup 2 to protect the top of the oil cup upper rubber body 3 and cover the airflow channel 31 to prevent air flow from overflowing from the top.

[0032] The oil leakage prevention structure of the electronic cigarette cartridge external oil bottle 1 further comprises an oil bottle rubber body 13 sealingly connected to the top of the oil bottle 1. The oil bottle rubber body 13 is made of food-grade silica gel material, is assembled on the oil bottle 1 after oil injection, and is in interference sealing with the oil bottle 1.

[0033] The top of the oil passing channel 23 is provided with an oil passing hole 27, and the bottom is provided with an oil passing groove 28, the oil passing hole 27 being connected to the oil storage cotton 5, and the oil passing groove 28 being connected to the bottom of the buffer oil storage 22. The oil passing hole 27 is connected to the oil absorption port 51 of the oil storage cotton, the excess tobacco tar of the oil storage cotton 5 is discharged from the oil passing hole 27, and then flows into the bottom of the buffer oil storage 22 through the position of the oil passing groove 28, so that the gradually accumulated tobacco tar can be temporarily stored in the buffer oil storage 22, and the oil passing channel 23 forms a flow guide channel for the tobacco tar after being squeezed out.

[0034] The oil leakage prevention structure of the electronic cigarette cartridge external oil bottle 1 further comprises an oil cup lower rubber body 9 and an oil cup sealing plug 29, the oil cup lower rubber body 9 being sealingly connected to the bottom of the atomization chamber 21, and the oil cup sealing plug 29 being sealingly connected to the bottom of the buffer oil storage 22. The silica gel plug of the oil cup 2 is made of food-grade silica gel material, is in interference sealing with the oil cup 2, and cooperates with the oil cup 2 to form the buffer oil storage 22. The lower silica gel of the oil cup 2 is made of food-grade silica gel material, is provided with an air hole, an atomization core assembly 6 mounting hole, and an atomization core lead mounting hole, and is in interference sealing with the oil cup 2 and the oil cup bottom cover 8.

[0035] The atomization core assembly 6 comprises a heating mesh, oil guiding cotton, and a fixed tube, the fixed tube being communicated with the suction nozzle 4, the heating mesh being connected to the fixed tube, and the oil guiding cotton being surrounded on the heating mesh.

The heating mesh is powered by the battery inside the electronic cigarette to generate heat, the oil guiding cotton is heated to atomize the tobacco tar, and the oil storage cotton 5 gradually permeates oil to the oil guiding cotton to supplement the oil amount of the oil guiding cotton.

[0036] The oil leakage prevention structure of the electronic cigarette cartridge is realized by the oil bottle 1.

[0037] As shown in Figure 5 and Figure 6 , when the user uses the electronic cigarette normally, the tobacco oil in the oil bottle 1 flows to the oil outlet hole 11 of the oil bottle through the oil outlet column 12, and then enters the oil storage cotton 5 through the oil absorption port 51 of the oil storage cotton 5 to normally supply the oil to the atomizing core assembly 6, and the excess tobacco oil flows to the oil cup 2 through the oil passing hole 27 and the oil passing groove 28 of the oil cup 2, so that the user can use the electronic cigarette normally.

[0038] When the air in the oil bottle 1 expands outward to squeeze the tobacco oil in the high-altitude negative pressure and high-temperature environment, as shown in Figure 8 , the silica gel of the oil cup 2 is provided with an exhaust passage 24; since the oil storage cotton 5 is filled with the tobacco oil, the flow resistance of the tobacco oil in the oil storage cotton 5 is much greater than that of the oil passing passage 23 of the buffer oil storage 22, and most of the tobacco oil squeezed out of the oil bottle 1 will flow to the buffer oil storage 22 of the oil cup 2 through the oil passing hole 27 and the oil passing groove 28 of the oil cup 2, as shown in Figure 7 , when the user uses the electronic cigarette again, the tobacco oil in the buffer oil storage 22 will flow back to the oil absorption port 51 of the oil storage cotton 5 through the oil passing hole 27 and the oil passing groove 28 of the oil cup 2 under the driving of the exhaust passage 24, the airflow passage 31 and the tobacco suction airflow (similar to the principle of sucking milk by a straw), and then is adsorbed by the oil storage cotton 5 and supplied to the atomizing core assembly 6, so as to avoid the tobacco oil from leaking to the surface of the product.
