Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic cigarettes, and particularly relates to a high-efficiency oil leakage-proof cartridge. BACKGROUND

[0002] The electronic cigarette mainly comprises a cartridge, a battery, an electronic cigarette microphone, the cartridge contains an oil cup with a suction nozzle, an atomization support, a ceramic atomizer, and an atomization base provided with an air inlet hole, the oil cup contains tobacco tar, wherein the battery is used for supplying power to the ceramic atomizer and the electronic cigarette microphone, the action of inhaling by a human mouth generates negative pressure in the electronic cigarette, the electronic cigarette microphone senses the negative pressure, and the battery supplies power to the ceramic atomizer. The tobacco tar flows into the ceramic atomizer, the ceramic atomizer atomizes the tobacco tar to form smoke, the human mouth inhales, air enters the cartridge from the air inlet hole, and the air and the smoke are inhaled by a person together through the suction nozzle. The heating wire of the ceramic atomizer is generally arranged at the bottom of the ceramic atomizer, the tobacco tar slowly permeates the ceramic atomizer to reach the heating wire, and then is heated and atomized by the heating wire. The atomized tobacco tar condenses to form liquid tobacco tar again, which flows on the atomization base, that is, around the air inlet hole; the electronic cigarette is generally used for one week or even longer, the tobacco tar is easy to slowly permeate the ceramic atomizer and drip on the atomization base; the liquid tobacco tar flowing on the atomization base is very easy to flow out from the air inlet hole, thereby dirtying the battery and the electronic cigarette microphone and other components; and moreover, when a user inhales the electronic cigarette too hard, the tobacco tar flowing around the air inlet hole is very easy to be directly inhaled by the user, which greatly affects the use experience.

[0003] Generally, when a user uses the electronic cigarette, the cigarette rod of the electronic cigarette faces downward, the tobacco tar completely covers the ceramic atomizer, the tobacco tar permeates to the heating wire, the heating wire heats and atomizes the tobacco tar to form smoke for the user to inhale. However, when the user lies down to inhale the electronic cigarette, the tobacco tar does not cover the ceramic atomizer, the tobacco tar does not permeate to the heating wire, but the heating wire still heats when the user inhales, which causes dry burning of the heating wire, and this easily causes damage to the heating wire, the smell after dry burning is very unpleasant, and this seriously affects the experience of the user.

[0004] In order to fully take away the smoke, the air inlet hole of the existing electronic cigarette is generally arranged directly below the ceramic atomizer, when the electronic cigarette is not used, the tobacco tar still continuously permeates the ceramic atomizer, the tobacco tar condenses at the bottom of the ceramic atomizer, and the tobacco tar dripping at the bottom of the ceramic atomizer is very easy to directly drip out from the air inlet hole, which causes leakage of the tobacco tar and greatly affects the use.

[0005] Therefore, the prior art has defects and needs to be improved. SUMMARY

[0006] The technical problem to be solved by the present application is to provide a high-efficiency oil leakage-proof cartridge, avoid leakage of atomized tobacco tar, avoid leakage of the tobacco tar, and avoid dry burning of the ceramic atomizer.

[0007] The technical scheme of the present application is as follows: an efficient oil leakage prevention cigarette cartridge is provided, comprising: a cartridge body, a hollow air inlet pipe; the cartridge body is provided with a tobacco oil cavity and an atomization cavity, and a ceramic atomizer of the cartridge body is arranged between the tobacco oil cavity and the atomization cavity; the hollow air inlet pipe penetrates through the cartridge body and extends into the atomization cavity, and the vertical distance from the air outlet hole of the hollow air inlet pipe extending into the atomization cavity to the bottom surface of the atomization cavity is greater than one fourth of the vertical distance from the bottom of the ceramic atomizer to the bottom surface of the atomization cavity. Preferably, the temperature resistance of the hollow air inlet pipe is greater than 150 DEG C.

[0008] The vertical distance from the air outlet hole of the hollow air inlet pipe to the bottom surface of the atomization cavity is greater than one fourth of the vertical distance from the bottom of the ceramic atomizer to the bottom surface of the atomization cavity, that is, the air outlet hole has a distance from the bottom surface of the atomization cavity, so that the condensed tobacco oil and the tobacco oil permeating the ceramic atomizer are accumulated in the range between the air outlet hole of the hollow air inlet pipe and the bottom surface of the atomization cavity, and the tobacco oil is not easy to enter the air outlet hole, that is, the tobacco oil is not easy to leak, thereby improving the user experience. The heating wire of the ceramic atomizer heats and atomizes the tobacco oil, if the hollow air inlet pipe is made of a material that is not resistant to high temperature, the hollow air inlet pipe close to the heating wire is easy to be burned and produce toxic substances, which is inhaled by people, thereby seriously affecting the health of the user, so the hollow air inlet pipe must be stable in nature under high temperature; the hollow air inlet pipe is preferably made of a material that can resist a temperature above 150 DEG C, so as to avoid the burning of the hollow air inlet pipe by the heat generated by the heating wire to produce toxic substances.

[0009] In order to further improve the oil leakage prevention effect, the vertical distance from the air outlet hole of the hollow air inlet pipe to the bottom surface of the atomization cavity can be set to be greater than one third or one half or two thirds or three fourths or four fifths or the like of the vertical distance from the bottom of the ceramic atomizer to the bottom surface of the atomization cavity.

[0010] The vertical distance from the bottom of the ceramic atomizer of the existing electronic cigarette cartridge to the bottom surface of the atomization cavity is generally 4mm-16mm, so the vertical distance from the air outlet hole to the bottom of the atomization cavity in the present scheme is at least 1mm.

[0011] Further, the air outlet hole is not directly opposite the bottom of the ceramic atomizer; the air outlet hole is arranged directly below the ceramic atomizer. The air outlet hole is not directly opposite the bottom of the ceramic atomizer, which can avoid the tobacco oil permeating the ceramic atomizer from directly dropping on the air outlet hole; the air outlet hole is arranged directly below the ceramic atomizer, and air enters the atomization cavity from the air outlet hole, which can fully carry away the smoke after the tobacco oil is atomized.

[0012] Further, the material of the hollow air inlet pipe is an inorganic material, such as metal (specifically, copper, stainless steel, etc.), ceramic, glass, oxide (specifically, magnet, aluminum oxide, silicon oxide). The inorganic material is stable in nature and can withstand the temperature generated by the heating wire without changing the substance.

[0013] Further, one insertion mode of the hollow air inlet pipe is that the hollow air inlet pipe extends into the atomization cavity from the bottom of the cartridge body, and the air outlet hole is arranged on the side of the hollow air inlet pipe.

[0014] Further, a limiting piece is arranged at the air outlet hole end of the hollow air inlet pipe, a movable movable ring is sleeved on the hollow air inlet pipe, the diameter of the limiting piece is greater than the diameter of the movable ring, and the width of the movable ring is greater than the maximum distance from the limiting piece to the air outlet hole. The hollow air inlet pipe extends into the atomization cavity from the bottom of the cartridge body, so when the user smokes the electronic cigarette while lying down, the movable ring will fall on the limiting piece, and the movable ring will block the air outlet hole, limiting the air from entering the atomization cavity. That is, the electronic cigarette will not generate negative pressure, and the microphone of the electronic cigarette will not be powered on, and the heating wire will not be dry. Thus, dry burning caused by lying down smoking is effectively avoided.

[0015] Further, in one specific scheme, the hollow air inlet pipe is a hollow electrode needle; the cartridge body comprises an oil cup, a silica gel sealing support, an atomization support, atomization silica gel, a ceramic atomizer arranged in the oil cup respectively, and an atomization base connected with the oil cup; the oil cup is provided with a mouthpiece extending into the inside of the oil cup, and the oil cup, the silica gel sealing support, the atomization support, the atomization silica gel, and the ceramic atomizer surround an e-liquid cavity; the oil cup, the atomization support, the atomization silica gel, and the atomization base surround an atomization cavity, and the atomization cavity is in communication with the mouthpiece; the hollow electrode needle abuts against a heating wire of the ceramic atomizer through the atomization base. The hollow electrode needle has the functions of electricity conduction and air inlet, and a separate air inlet pipe is not needed, thereby saving cost, optimizing layout, and facilitating assembly. Preferably, the cartridge body further comprises a magnetic column mounted on the atomization base and an oil absorbing cotton arranged on the atomization base.

[0016] Further, in another specific scheme, the hollow air inlet pipe is a hollow magnetic column, and the cartridge body comprises an oil cup, a silica gel sealing support, an atomization support, atomization silica gel, a ceramic atomizer arranged in the oil cup respectively, an atomization base connected with the oil cup, and an electrode needle passing through the atomization base; the oil cup is provided with a mouthpiece extending into the inside of the oil cup, and the oil cup, the silica gel sealing support, the atomization support, the atomization silica gel, and the ceramic atomizer surround an e-liquid cavity; the oil cup, the atomization support, the atomization silica gel, and the atomization base surround an atomization cavity, and the atomization cavity is in communication with the mouthpiece; the electrode needle abuts against a heating wire of the ceramic atomizer. The hollow magnetic column has the functions of adsorption and air inlet, and a separate air inlet pipe is not needed, thereby saving cost, optimizing layout, and facilitating assembly. Preferably, the cartridge body further comprises an oil absorbing cotton arranged on the atomization base.

[0017] Furthermore, another way to insert the hollow air intake tube is as follows: the hollow air intake tube passes through the body of the cartridge from the side and extends into the atomizing chamber.

[0018] Furthermore, the air outlet is located on the side of the hollow air intake pipe; or, the air outlet is located on the end face of the hollow air intake pipe.

[0019] Furthermore, when the hollow air intake pipe is neither a hollow electrode pin nor a hollow magnetic column, the cartridge body includes: an oil cup, a silicone sealing bracket, an atomizing bracket, atomizing silicone, a ceramic atomizer, and an atomizing base connected to the oil cup, all disposed within the oil cup; an electrode pin passing through the atomizing base; the oil cup is provided with a mouthpiece extending into the oil cup; the oil cup, silicone sealing bracket, atomizing bracket, atomizing silicone, and ceramic atomizer form an e-liquid chamber; the oil cup, atomizing bracket, atomizing silicone, and atomizing base form an atomizing chamber; the atomizing chamber communicates with the mouthpiece; the electrode pin abuts against the heating wire of the ceramic atomizer. Preferably, the cartridge body further includes: a magnetic column installed at the bottom of the atomizing base, and oil-absorbing cotton disposed on the atomizing base.

[0020] By adopting the above solution, the present invention provides a highly efficient leak-proof e-cigarette cartridge. The vertical distance from the air outlet of the hollow air inlet tube to the bottom surface of the atomizing chamber is greater than one-quarter of the vertical distance from the bottom of the ceramic atomizer to the bottom surface of the atomizing chamber. In other words, there is a distance between the air outlet and the bottom surface of the atomizing chamber. Therefore, the condensed e-liquid and the e-liquid that has permeated the ceramic atomizer will accumulate in the area between the air outlet of the hollow air inlet tube and the bottom surface of the atomizing chamber. E-liquid is not easy to enter the air outlet, that is, e-liquid is not easy to leak, thus improving the user experience. Attached Figure Description
