Description

Technical Field

[0001] The present invention relates to the field of electronic products, and in particular to a cigarette cartridge and an electronic cigarette with an anti-leakage oil structure. Background Art

[0002] Electronic cigarettes are electronic products that imitate cigarettes. Currently, cartridge-type electronic cigarettes are a more common type of electronic cigarette. The cartridge and cigarette rod of this type of electronic cigarette exist in a separate form. The cigarette rod and cartridge that match each other are detachably fixed to each other to form the cartridge-type electronic cigarette. An atomization component for atomizing the smoke oil is provided in the cigarette cartridge. Users can choose smoke oils with different flavors by replacing different cigarette cartridges during use, thereby experiencing different atomization flavors.

[0003] In the process of using replaceable cartridge electronic cigarettes, users will purchase a variety of cartridges with different flavors, and the same cigarette rod will be assembled and disassembled many times for different cartridges. Therefore, the uniformity of the quality of various cartridges and the reliability of the cooperation between the cartridge and the cigarette rod are crucial to the normal use of electronic cigarettes. The atomization assembly of the existing cartridge is arranged to be in contact with the smoke oil when leaving the factory, which not only easily causes the smoke oil stored in the cigarette chamber of the cartridge to leak through the atomization assembly during the transportation of the cartridge, but also may cause the atomization assembly to be in contact with the smoke oil for a long time due to the long-term non-use of the cartridge, resulting in the formation of a chemical reaction layer on the surface of the part of the atomization assembly that is in contact with the smoke oil, which has an adverse effect on the actual atomization effect of the cartridge.

[0004] Therefore, it is urgently necessary to provide a cigarette cartridge with an anti-leakage structure and an electronic cigarette with the cigarette cartridge, which can prevent oil leakage and have a good atomization effect, so that when the cigarette cartridge is not in use, its atomization component does not contact with the smoke oil, and can prevent oil leakage. Summary of the invention

[0005] In view of the deficiencies of the above-mentioned prior art and to achieve one purpose of the present invention, a cigarette cartridge with an anti-leakage structure is provided, which includes a cigarette bin, a base assembly, an atomizer assembly and a clamp. The cigarette bin is used to store cigarette oil and includes an open end. The base assembly includes a base and a heating core arranged at the open end. The heating core is slidably arranged in the base. The atomizer assembly is fixed on the heating core. The heating core is provided with a slot. The clip is detachably clamped in the slot to limit the movement of the heating core relative to the base.

[0006] Furthermore, a seat hole is provided on the base, the heating core is inserted into the seat hole, the atomization assembly includes a heating wire and a ceramic atomization core, and the heating core is electrically connected to the heating wire and the ceramic atomization core.

[0007] Furthermore, the clamp includes a pair of opposite elastic clamping arms, and the clamping slots are provided in a pair and correspond one to one with the elastic clamping arms.

[0008] Furthermore, the clamp includes a central portion, a pair of elastic clamp arms respectively extending symmetrically from the central portion along an arc direction, the heating core is cylindrical, and a pair of clamp grooves are symmetrically opened on the peripheral wall of the cylinder.

[0009] Furthermore, a protrusion is provided at the center portion, and a convex rib is provided near the slot of the heating core. The protrusion is used for gripping so that the elastic clamping arm moves relative to the corresponding slot under the guidance of the corresponding convex rib to achieve engagement or disengagement.

[0010] Furthermore, the cigarette cartridge also includes an elastic oil storage sleeve, which is arranged between the base and the cigarette bin, and an oil storage chamber for accommodating the smoke oil from the cigarette bin is formed between the oil storage sleeve and the base. When the clip is engaged in the slot, the atomizer assembly is away from the oil storage chamber. When the clip is disengaged from the slot and the heating core is pushed in the base toward the cigarette bin, the atomizer assembly is inserted into the oil storage chamber.

[0011] Furthermore, the cigarette cartridge also includes a flue pipe and a cigarette holder assembly, the cigarette bin also includes a smoke outlet end, the cigarette holder assembly is arranged at the smoke outlet end, the cigarette holder assembly includes a cigarette holder shell and a cigarette holder head, the cigarette holder shell is sleeved on the outer periphery of the cigarette bin, the cigarette holder head is fixed on the cigarette holder shell and plugged into the smoke outlet of the cigarette bin, one end of the flue pipe accommodated in the cigarette bin is connected to the oil storage chamber and the other end is connected to the cigarette holder head, the atomization assembly is inserted into the oil storage chamber and also inserted into the flue pipe to atomize the tobacco oil from the oil storage chamber in the flue pipe.

[0012] Furthermore, the oil storage sleeve has a recessed portion with a through hole, the inner wall of the through hole is compressively sleeved on the outer periphery of the base, the outer wall of the recessed portion abuts against the inner peripheral wall of the cigarette bin, and the base has a seat plate facing the recessed portion, and an oil storage cavity is formed between the recessed portion and the seat plate. The tobacco oil in the cigarette bin enters the oil storage cavity through the gap between the inner wall and the base formed by the elastic deformation of the through hole.

[0013] Furthermore, an elastic sealing member is provided on the base plate, and the sealing member has an opening that is elastically opened and closed, and the atomizing assembly passes through the opening to be inserted into the oil storage cavity and the flue pipe.

[0014] To achieve another object of the present invention, the present invention also provides an electronic cigarette, which includes a cigarette rod and a cigarette cartridge, wherein the cigarette cartridge is any one of the cigarette cartridges with an anti-leakage structure, and when the clip is removed relative to the slot, the cigarette cartridge can be detachably fixed to the cigarette rod.

[0015] The beneficial effects of the present invention are as follows: the cigarette cartridge with an anti-leakage structure adopts a clip to limit the movement of the heating core of the atomizer assembly relative to the base, so that before the cigarette cartridge is actually used, not only can the atomizer assembly be isolated from the smoke oil, so that the atomizer assembly does not contact the smoke oil and thus can avoid the occurrence of oil leakage, but also the atomizer assembly can be further prevented from being in contact with the smoke oil for a long time, thereby ensuring that the cigarette cartridge has a good atomization effect.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] refer to Figures 1 to 3The present invention provides a cigarette cartridge 100 with an anti-leakage structure, which includes a cigarette bin 10, a base assembly 20, an atomizer assembly 30 and a clip 80. The cigarette bin 10 is hollow and made of transparent plastic for storing cigarette oil. The cigarette bin 10 includes an open end and a smoke outlet end. The base assembly includes a base 21 and a heating core 22 arranged at the open end, and the open end is sealed by the base 21. The heating core 22 is slidably arranged in the base 21, and the atomizer assembly 30 is fixed on the heating core 22. The heating core 22 is provided with an electrical contact electrically connected to the atomizer assembly 30. When the cigarette cartridge 100 is detachably fixed to the cigarette rod, the electrical contact on the heating core 22 is electrically connected to the electrical contact on the cigarette rod, so that the battery in the cigarette rod and the controller electrically connected to the battery can respectively supply power to and control the atomizer assembly 30. A slot 22A is provided on the heating core 22, and the clip 80 is engaged in the slot 22A to limit the movement of the heating core 22 relative to the base 21. Therefore, the anti-leakage structure of the cigarette cartridge of the present invention mainly adopts the clip 80 and the slot 22A matched therewith. When the clip 80 is engaged in the slot 22A, the heating core 80 cannot move relative to the base 21 and contact the smoke oil stored in the cigarette cartridge 100, ensuring that the atomizer component 30 will not contact the smoke oil before the actual use of the cigarette cartridge 100, which can avoid oil leakage of the cigarette cartridge 100 and further avoid the contact between the atomizer component 30 and the smoke oil for a long time before the actual use of the cigarette cartridge 100, preventing the surface of the atomizer component 40, especially the ceramic atomizer core 32 (which will be further explained below) from contacting with the smoke oil for a long time and chemically reacting to produce a chemical reaction layer, thereby ensuring that the atomizer component 30 has a good atomization effect on the smoke oil. When the cigarette cartridge 100 is actually needed, the user removes the clip 80 from the heating core 22, and then pushes the heating core 22 along the base toward the cigarette bin 10, so that the atomization assembly 30 can contact the cigarette oil to perform the atomization operation.

[0023] Preferably, a seat hole (not shown) is provided on the base 21, and the heating core 22 is inserted into the seat hole. Specifically, the heating core 22 is inserted into the seat hole with an interference fit. The atomizer assembly 30 includes a heating wire 31 and a ceramic atomizer core 32. The heating core 22 is electrically connected to the heating wire 31 and the ceramic atomizer core 32. That is, the atomizer assembly 30 is connected and fixed to the heating core 22 through the heating wire 31. The clamp 80 can limit the relative movement of the heating core 22 in the seat hole in the direction close to the cigarette bin 10, thereby preventing the atomizer assembly 30 from contacting the cigarette oil and causing oil leakage.

[0024] As a specific embodiment of the clip 80, the clip 80 includes a pair of opposing elastic arms 81, and the slots 22A are set as a pair and correspond one-to-one to the elastic arms 81. The user operates the elastic arms 81 to elastically deform them, and the free ends of the elastic arms 81 can be inserted into or out of the slots 22A, thereby preventing or allowing the heating core 22 to move relative to the base 21.

[0025] In order to improve the stability of the clamp 80 in the clamping slot 22A, preferably, the clamp 80 includes a central portion 82, a pair of elastic clamping arms 81 extend symmetrically from the central portion 82 along an arc direction, the heating core 22 is cylindrical, and a pair of clamping slots 22A are symmetrically opened on the peripheral wall of the cylinder.

[0026] As a further improvement, the center portion 82 is provided with a protrusion 83, which can facilitate the user to grasp the clip 80, thereby improving the convenience of using the clip 80. The heating core 22 is provided with a rib 22B adjacent to the slot 22A. The protrusion 83 is used for grasping so that the elastic clip arm 81 can be moved relative to the corresponding slot 22A under the guidance of the corresponding rib 22B to achieve engagement or disengagement. By setting the rib 22B, not only can the free end of the elastic clip arm 81 be guided to move toward or away from the slot 22A, but the elastic deformation of the elastic clip arm 81 can also be gradually increased or decreased, thereby increasing the stability of the user's operation of the clip 80.

[0027] As a specific embodiment of storing the tobacco oil that the atomizer assembly 30 can contact, the cigarette cartridge 100 also includes an elastic oil storage sleeve 40, which is arranged between the base 21 and the cigarette bin 10, and an oil storage chamber 70 for accommodating the tobacco oil from the cigarette bin 10 is formed between the oil storage sleeve 40 and the base 21, that is, the cigarette cartridge 100 has two spaces for storing tobacco oil, namely the hollow part of the cigarette bin 10 and the above-mentioned oil storage chamber 70. When the clip 80 is engaged in the slot 22A, the atomizer assembly 30 is away from the oil storage chamber 70, and the atomizer assembly 30 is not in contact with the tobacco oil; when the clip 80 is disengaged from the slot 22A and the heating core 22 is pushed in the base 21 toward the cigarette bin 100, the atomizer assembly 30 is inserted into the oil storage chamber 70, and the atomizer assembly 30 is in contact with the tobacco oil. It should be understood that the smoke oil in the smoke cartridge 100 can also be stored in other structures, as long as the atomizer assembly 30 can be installed or removed relative to the heating core 22 to achieve non-contact or contact between the atomizer assembly 30 and the smoke oil.

[0028] As a further improvement, the cigarette cartridge 100 further includes a flue pipe 50 and a mouthpiece assembly 60, the cigarette bin 10 further includes a smoke outlet end, the mouthpiece assembly 60 is arranged at the smoke outlet end, the mouthpiece assembly 60 includes a mouthpiece housing 61 and a mouthpiece head 62, the mouthpiece head 62 can be made of silicone material, the mouthpiece housing 61 is sleeved on the outer periphery of the cigarette bin 10, the mouthpiece head 62 is fixed on the mouthpiece housing 61 and plugged into the smoke outlet of the cigarette bin 10, one end of the flue pipe 50 accommodated in the cigarette bin 10 is connected to the oil storage chamber 70 and the other end is connected to the mouthpiece head 62, preferably, the end of the flue pipe 50 connected to the oil storage chamber 70 is fixedly connected to the base 21. The atomization assembly 30 is inserted into the oil storage chamber 70 and also inserted into the flue pipe 50 to atomize the smoke oil from the oil storage chamber 70 in the flue pipe 50. In addition, the cigarette magazine 10 and the cigarette holder shell 61 are adapted to each other and are both in a tapered fish-head shape, and the smoke exhaust port and the cigarette holder head 62 are respectively arranged at the fish-mouth positions of the corresponding fish-head-shaped cigarette magazine 10 and the cigarette holder shell 61. Therefore, the structure of the cigarette cartridge 100 is compact and easy for users to grasp, and the cigarette holder head 62 can be easily replaced by users, thereby improving the cleanliness of use.

[0029] Preferably, the oil storage sleeve 40 has a recessed portion 41 with a through hole, the inner wall 42 of the through hole is compressed and sleeved on the outer periphery of the base 21, and the oil storage sleeve 40 can be specifically made of silicone material, and the outer wall 43 of the recessed portion 41 abuts against the inner peripheral wall of the cigarette bin 10. In this way, when the cigarette cartridge 100 leaves the factory or is transported, only a small part of the smoke oil in the cigarette bin 10 may enter the oil storage cavity through the gap between the inner wall of the through hole and the outer periphery of the base. Since the volume of the recessed portion 41 is constant, the outer wall 43 of the recessed portion 41 always abuts against the inner peripheral wall of the cigarette bin 10 during the elastic deformation of the through hole, thereby ensuring the sealing performance of the cigarette cartridge 100 for the smoke oil. The base 21 has a seat plate (not shown) facing the recessed portion 41, and the above-mentioned oil storage chamber 70 is formed between the recessed portion 41 and the seat plate. The oil in the cigarette cartridge 10 enters the oil storage chamber 70 through the gap between the inner wall 42 and the base 21 formed by the elastic deformation of the through hole. The elastic deformation is caused by the negative pressure formed in the oil storage chamber 70 when the cigarette cartridge 100 is in a working state and the atomizer assembly 30 is working, assembling the cigarette cartridge or transporting the cigarette cartridge. Therefore, when the cigarette cartridge 100 is working for the first time, the atomizer assembly 30 acts on the air in the oil storage chamber 70 to form a negative pressure, and the oil in the cigarette cartridge 10 enters the oil storage chamber 70 through the above-mentioned gap. When the cigarette cartridge 100 works after the first time, the atomizer assembly 30 atomizes the oil in the oil storage chamber 70 to form a negative pressure, and the oil in the cigarette cartridge 10 enters the oil storage chamber 70 through the above-mentioned gap to fill the volume occupied by the atomized oil. In addition, during the process of assembling the cigarette cartridge 100 or transporting the cigarette cartridge 100, even if the cigarette oil enters the oil storage chamber 70, the clamp 80 can prevent the atomization assembly 30 from contacting the cigarette oil before the cigarette cartridge 100 is actually used.

[0030] As a further improvement, preferably, an elastic seal (not shown) made of silicone or rubber is provided on the base plate, and the seal has an opening that is elastically opened and closed, and the atomizer assembly 30 is inserted into the flue pipe 50 through the opening. Since the part of the atomizer assembly 30 inserted into the flue pipe 50 is generally needle-shaped, the elastic seal ensures that the smoke oil will not leak out through the atomizer assembly 30 to a large extent, and since the clamp 80 of the smoke cartridge 100 can limit the degree of insertion of the atomizer assembly 30 into the opening before the actual use of the smoke cartridge 100, the possibility of smoke oil leakage is further reduced. In addition, when the smoke cartridge 100 is detachably fixed to the cigarette rod, the adsorption member such as a sponge provided on the cigarette rod abuts against the surrounding of the heating core 22. In this way, even if there is an accidental situation of smoke oil leakage, the adsorption member can also absorb the leaked smoke oil to ensure the normal use of the electronic cigarette.

[0031] Optionally, a protrusion 21A is provided on the base 21, and a groove 11A is provided on the cigarette chamber 10 to snap into the protrusion 21A. In this way, the assembly of the base 21 and the cigarette chamber 10 can be facilitated, and the compatibility of the same base 21 with different cigarette chambers 10 can be facilitated, thereby reducing the production cost of the mold and even the cigarette cartridge 100.

[0032] Optionally, as a specific embodiment of the flue pipe 50, it includes a first flue pipe 51 and a second flue pipe 52 made of metal material and silicone material respectively. The first flue pipe 51 is a stepped pipe, and the second flue pipe 52 is sleeved on the first flue pipe 51 and buckled with the stepped surface. Therefore, since the atomized smoke oil has a certain high temperature and the smoke oil has a certain viscosity, the first flue pipe 51 is made of metal material, which not only makes it have good heat resistance but also prevents excessive smoke oil from adhering to the periphery of the flue pipe 50 and causing waste. The second flue pipe 52 is made of silicone material and is sleeved on the first flue pipe 51, more specifically, the first sub-tube (see the description below) and buckled with the stepped surface. The silicone material can prevent the first sub-tube from being raised by the smoke. The temperature is transferred to the oil in the cigarette bin 10, causing adverse changes in the chemical properties and viscosity of the oil. The inlet end of the first smoke duct tube 51 is located in the oil storage chamber 70 and the atomizer assembly 30 is inserted into the first smoke duct tube 51. The outlet end of the first smoke duct tube 51 abuts against the mouthpiece 62. By setting the first smoke duct tube 51 as a stepped tube with a first sub-tube and a second sub-tube, and the diameter of the first sub-tube with the inlet end is larger than the diameter of the second sub-tube with the outlet end, the space of the first sub-tube is larger than the space of the second sub-tube, so the atomized oil has a certain residence and diffusion mixing time in the first sub-tube, so that the uniformity of the smoke is good, and the second sub-tube has a certain compression and discharge effect on the smoke, so that it is easy to control the amount of smoke discharged that is suitable for user experience.

[0033] The present invention also provides an electronic cigarette, which includes any of the above-mentioned cartridges 100 and a cigarette rod with an anti-leakage structure, and when the clamp 80 is removed relative to the slot 22A, the cartridge 100 can be detachably fixed to the cigarette rod, thereby realizing various functions of the electronic cigarette including atomizing oil smoke. Therefore, before the cartridge 100 and the cigarette rod are detachably fixed, the clamp 80 of the cartridge 100 prevents the atomization assembly 30 from contacting the oil, thereby preventing the oil from leaking.

[0034] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
