Description

Technical Field

[0001] The present invention relates to an electronic cigarette, and particularly to a direct-oil type electronic cigarette. Background Art

[0002] In existing electronic cigarettes, especially disposable electronic cigarettes, absorbent cotton is generally used to store e-liquid.

[0003] Currently, in well-known electronic cigarettes, especially disposable ones, e-liquid is stored by absorbent cotton, which has the following defects: 1. As the e-liquid is continuously used, the amount of e-liquid in the absorbent cotton gradually decreases, and the amount of e-liquid supplied to the atomizing core also gradually decreases, resulting in a gradually lighter taste of the cigarette and inconsistent taste before and after; 2. Approximately 20% of the e-liquid in the absorbent cotton is adsorbed in the absorbent cotton and cannot be conducted to the atomizing core, so the e-liquid cannot be fully used, causing waste; 3. Although many seals are used to prevent oil leakage, the problem of oil leakage in the product has never been well solved; 4. As users' requirements for the number of puffs increase, the size of the cigarette becomes larger and larger; 5. It is not convenient for automated assembly, with low production efficiency and high costs.

[0004] To avoid the above problems, this patent application proposes an electronic cigarette with a completely new structure, which thoroughly solves: 1. The problem of inconsistent taste before and after of the electronic cigarette; 2. The problem of oil leakage of the electronic cigarette; 3. The problem of full utilization of e-liquid; 4. The problem of meeting a large number of puffs; 5. Partially realizing automated assembly, improving production efficiency, and reducing manufacturing costs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a direct-oil type electronic cigarette in view of the deficiencies of the prior art.

[0006] To achieve the above object, the measures taken by the present invention are as follows:

[0007] A direct-oil type electronic cigarette includes an oil container sleeved inside an electronic cigarette housing. The oil container is composed of an oil cup and an oil storage seat. The oil storage seat is sleeved inside the oil cup. An oil storage device is sleeved inside the oil storage seat hole of the oil storage seat. An oil guiding core is sleeved inside the central through hole of the oil storage device of the oil storage device. Both ends of the oil guiding core respectively extend to the outside of both ends of the central through hole of the oil storage device. The I end of the oil guiding core is sleeved inside the central hole of the absorbent cotton of the absorbent cotton, and the K end extends into the oil container. An absorbent cotton is sleeved inside the central hole of the air collecting cover. An atomizing core is sleeved inside the central hole of the absorbent cotton of the absorbent cotton. An air collecting cover is arranged at the upper end surface A of the oil storage seat. The air collecting cover centrally guides the gas passing through the gap formed by the side of the oil container and the inner hole of the housing into the central hole of the absorbent cotton of the absorbent cotton;

[0008] The described oil reservoir is made of plastic, especially food-grade plastic, and the oil cup and the oil reservoir seat are injection-molded by a mold. The oil reservoir seat and the oil cup are tightly connected or ultrasonically welded to form the oil reservoir. One or more ribs or grooves are formed on the outer surface of the oil reservoir, and one or more gaps are formed in cooperation with the inner hole of the outer shell for side ventilation and wiring. The cross-section of the oil reservoir can be circular, oval, rectangular, square or polygonal; and other different shapes; the oil reservoir is installed in the oil reservoir seat hole of the oil reservoir seat and is tightly connected with the oil reservoir seat hole of the oil reservoir seat;

[0009] The described oil reservoir is injection-molded from plastic, especially food-grade plastic. A set of annular ribs and annular grooves are arranged on the cylindrical outer surface of the oil reservoir along the circumferential direction. The widths of the annular grooves in each group are equal, and the widths of the annular grooves in different groups are not equal. From end E to end F of each group of annular grooves, the width gradually increases. The width of the annular groove is in the range of 0.1 - 0.5 mm, and the depth of the annular groove is in the range of 0.5 - 4.5 mm; the function of the annular groove is to store e-liquid;

[0010] An oil reservoir air return groove is formed on the outside of the described oil reservoir along the length direction. The oil reservoir air return groove penetrates through the annular ribs, annular grooves and surface D. From the F end face to the B end face, at the F end face, a slot hole communicating with the central through hole of the oil reservoir is provided at the oil reservoir air return groove. The width of the oil reservoir air return groove is in the range of 0.1 - 0.5 mm, and the depth of the oil reservoir air return groove is deeper than the depth of the annular groove. Generally, the width of the slot hole is the same as the width of the oil reservoir air return groove;

[0011] The function of the oil reservoir air return groove is to keep the oil pressure in the oil reservoir balanced with the external environment. When the oil pressure in the oil reservoir is higher than the external environment pressure, the air holes in the oil reservoir are discharged through the oil reservoir air return groove. In this process, e-liquid is also discharged along with the oil reservoir air return groove or the oil guiding core. The discharged e-liquid is adsorbed and stored in the annular groove, preventing e-liquid leakage. When the pressure in the oil reservoir is lower than the environmental pressure. Under the action of the external environmental pressure and the suction force inside the oil reservoir, the e-liquid in the annular groove flows back into the oil reservoir along the oil reservoir air return groove or the oil guiding core. In this way, exhaust, oil discharge, air return, and oil return are reciprocally circulated, ensuring that e-liquid does not leak;

[0012] An oil reservoir dividing groove with a width greater than 0.5 mm is formed on the outside of the described oil reservoir along the length direction and in the direction symmetrical to the oil reservoir air return groove, penetrating through the annular ribs and annular grooves from the F end to the E end. A dividing groove hole communicating with the central through hole of the oil reservoir can be formed in the oil reservoir dividing groove;

[0013] The main function of the oil reservoir dividing groove is to divide the e-liquid in the annular groove, reduce the suction force between the e-liquids in the annular groove, and facilitate the e-liquid in the annular groove to flow back into the oil reservoir along the oil reservoir air return groove;

[0014] The cylindrical diameters of the D, H, and G surfaces of the described oil storage device are 0.05 - 0.15 mm larger than the diameter of the annular rib; this facilitates the tight assembly of the oil storage device with the oil storage seat hole without damaging the annular rib and the annular groove;

[0015] The described oil guiding core is made of fiber material. An oil guiding core groove is opened at the I end of the oil guiding core for wire routing and ventilation. The oil guiding core is moderately tightly fitted with the central hole of the oil storage device and the oil absorbing cotton;

[0016] The shape and size of the end face C of the described air collecting cover are the same as those of the cross-section of the outer housing. The end face C of the air collecting cover contacts the rib surface or the groove hole surface on the upper end face A of the oil storage seat, forming one or more gaps for gas passage and wiring;

[0017] The described oil absorbing cotton has an atomizing core sleeved in its central hole. The oil absorbing cotton is made of fiber material and functions to absorb and guide oil;

[0018] The atomizing core is sleeved in the central hole of the oil absorbing cotton. The air collecting cover concentrates the airflow passing through the pores formed by the ribs or grooves on the side of the oil holding device and the inner hole of the outer housing into the central hole of the oil absorbing cotton sleeved in the central hole of the air collecting cover. When smoking, the atomizing core is energized to generate heat, atomizing the e-liquid in contact with the atomizing core, and the atomized smoke is sucked out through the central hole of the oil absorbing cotton via the mouthpiece;

[0019] The oil storage device is a cylindrical structure, and the diameter of its central through hole is 1.5 - 10 millimeters.

[0020] The beneficial effects of the present invention: practical, novel in structure, and low in production cost; it solves the problems of inconsistent taste before and after of e-cigarettes, e-liquid leakage, e-liquid residue, and limited puff count, and is easy to achieve partial automated assembly, reducing the manufacturing cost.

The oil storage device 1 is composed of an oil storage cup 1-2 and an oil storage base 1-1. The oil storage cup 1-2 sleeves the oil storage base 1-1. An oil storage device 2 is sleeved in an oil storage base hole 1-4 of the oil storage base 1-1. An oil guiding core 4 is sleeved in a central through hole 2-6 of the oil storage device 2. Both ends of the oil guiding core 4 respectively extend to the outside of both ends of the central through hole 2-6 of the oil storage device 2. The I end of the oil guiding core 4 is sleeved in a central hole 3-1 of the oil absorbing cotton 3. The K end extends into the oil storage device 1. An oil absorbing cotton 3 is sleeved in a central hole 6-1 of the air collecting hood 6. An atomizing core 5 is sleeved in the central hole 3-1 of the oil absorbing cotton 3. An air collecting hood 6 is arranged at the upper end surface A of the oil storage base 1-1. The air collecting hood 6 centrally guides the gas passing through the gap formed by the side surface of the oil storage device 1 and the inner hole of the outer housing 9 into the central hole 3-1 of the oil absorbing cotton 3.

[0037] The oil guiding core 4 is moderately tightly fitted with the central through hole 2-6 of the oil storage device and the central hole 3-1 of the oil absorbing cotton, and the oil absorbing cotton 3 plays a role in guiding oil.

[0038] The described oil container 1 is injection-molded from plastic, especially food-grade plastic, into an oil cup 1-2 and an oil reservoir seat 1-1. The oil reservoir seat 1-1 and the oil cup 1-2 are tightly connected or ultrasonically welded to form the oil container 1. One or more ribs or grooves are provided on the outer surface of the oil container 1, which cooperate with the inner hole of the outer housing 9 to form one or more gaps for side ventilation and wiring. The cross-section of the oil container 1 can be circular, oval, rectangular, square or polygonal, etc., in other different shapes. The oil reservoir 2 is installed in the oil reservoir seat hole 1-4 of the oil reservoir seat 1-1 and is tightly connected to the oil reservoir seat hole 1-4 of the oil reservoir seat 2.

[0039] The described oil reservoir 2 is injection-molded from plastic, especially food-grade plastic. Along the circumferential direction on the cylindrical outer surface of the oil reservoir 2, 1 to 3 groups of annular ribs 2-2 and annular grooves 2-1 are provided. The widths of the annular grooves 2-1 within each group are equal, while the widths of the annular grooves 2-1 in different groups are not equal. From the E end to the F end of each group of annular grooves 2-1, the width gradually increases. The width of the annular groove 2-1 is in the range of 0.1 to 0.5 mm, and the depth of the annular groove 2-1 is in the range of 0.5 to 4.5 mm. The function of the annular groove 2-1 is to store e-liquid.

[0040] An oil reservoir air return groove 2-4 is provided on the outside of the oil reservoir 2 along the length direction. The oil reservoir air return groove 2-4 penetrates through the annular rib 2-2, the annular groove 2-1 and the D surface. From the F end face to the B end face, at the F end face, a slot hole 2-7 communicating with the central through hole 2-6 of the oil reservoir is provided at the oil reservoir air return groove 2-4. The width of the oil reservoir air return groove 2-4 is in the range of 0.1 to 0.5 mm. The depth of the oil reservoir air return groove 2-4 is deeper than the depth of the annular groove 2-1. The width of the slot hole 2-7 is the same as the width of the oil reservoir air return groove 2-4.

[0041] The function of the oil reservoir air return groove 2-4 is to keep the oil pressure in the oil container 1 balanced with the external environment. When the oil pressure in the oil container 1 is higher than the external environment pressure, the gas in the oil container 1 is discharged through the oil reservoir air return groove 2-4. In this process, e-liquid also flows out along the oil reservoir air return groove 2-4 or the wick 4. At this time, the discharged e-liquid is adsorbed and stored in the annular groove 2-1, preventing e-liquid leakage. When the pressure in the oil container 1 is lower than the external environment pressure, under the action of the external environment pressure and suction, the e-liquid in the annular groove 2-1 flows back into the oil container 1 along the oil reservoir air return groove 2-4 or the wick 4. In this way, exhaust, oil discharge, air return, and oil return are reciprocally circulated, ensuring that e-liquid does not leak.

[0042] An oil reservoir breaking groove 2-3 with a width greater than 0.5 mm is provided on the outside of the oil reservoir 2 along the length direction and in the direction symmetrical to the oil reservoir air return groove 2-4. The oil reservoir breaking groove 2-3 penetrates through the annular rib 2-2 and the annular groove 2-1 from the F end to the E end. A breaking slot hole communicating with the central through hole 2-6 of the oil reservoir can be provided in the oil reservoir breaking groove 2-3.

[0043] The main function of the oil storage divider groove 2-3 is to divide the tobacco oil in the annular groove 2-1, reduce the mutual tension between the tobacco oils in the annular groove 2-1, and facilitate the tobacco oil in the annular groove 2-1 to flow back into the oil receiver 1 along the air return groove 2-4 of the oil storage device.

[0044] The cylindrical diameters of the D surface, H surface and G surface of the oil storage device 2 are 0.05 - 0.15 mm larger than the diameter of the annular rib 2-2. This is convenient for the tight assembly of the oil storage device 2 with the oil storage seat hole 1-4 without damaging the annular rib 2-2 and the annular groove 2-1. The oil guiding core 4 or the oil guiding pipe made of cellulose fiber bundle is moderately fitted with the central hole 2-6 of the oil storage device.

[0045] The oil guiding core 4 is made of fiber material. An oil guiding core groove 4-1 is opened at the I end of the oil guiding core 4 for wire routing and ventilation. The oil guiding core 4 is made of fiber filament material and is moderately tightly fitted with the inner through hole 2-6 of the oil storage device and the central hole 3-1 of the oil absorbing cotton.

[0046] The shape and size of the end face C of the air collecting cover 6 are the same as the cross-sectional shape and size of the outer shell 9, and are in transitional fit with the inner hole of the e-cigarette shell 9. The end face C of the air collecting cover 6 contacts the rib surface 1-9 or the groove hole surface on the upper end face A of the oil storage seat 1-1 to form one or more voids for gas passage and wiring.

[0047] An atomizing core 5 is sleeved in the central hole 3-1 of the oil absorbing cotton 3 of the oil absorbing cotton 3. The oil absorbing cotton 3 is made of fiber material and functions to absorb and guide oil.

The atomizing core 5 is moderately tightly fitted with the central hole 3-1 of the oil absorbing cotton 3. The power line is led out from the oil guiding core groove 4-1 at the I end of the oil guiding core 4. The air collecting cover 6 concentrates the airflow passing through the pores formed by the ribs or grooves on the side of the oil receiver 1 and the inner hole of the e-cigarette shell 9 into the central hole 3-1 of the oil absorbing cotton 3 of the oil absorbing cotton 3. When smoking, the atomizing core 5 is energized and heated to atomize the tobacco oil around the atomizing core 5. The atomized tobacco oil is sucked out through the mouthpiece along the central hole 3-1 of the oil absorbing cotton 3 of the oil absorbing cotton 3. The oil storage device 2 is a cylindrical structure, and the diameter of the central through hole 2-6 of the oil storage device is 1.5 - 10 mm.
