TECHNICAL FIELD

The present invention relates to an atomization generating device and an e-cigarette including the atomization generating device, and more particularly to an atomization generating device capable of controlling supply of e-cigarette liquid via closing and opening a liquid tank by relative movement of components and an e-cigarette including the atomization generating device.

BACKGROUND

The current e-cigarette is generally composed of an e-cigarette power supply control device, that is, a main body, and e-cigarette liquid supply, atomization, suction and other devices (collectively referred to as a cartridge). The inside of the main body is provided with a circuit board, that is, a control circuit, a battery and a butting terminal, the battery is connected to the circuit board, the circuit board is connected to the butting terminal, the surface of the cartridge is provided with a conductive terminal, the inside of the cartridge is provided with an atomizing chamber or an atomizer, and the inside of the atomizing chamber is provided with an atomizing core for heating and atomizing an e-cigarette liquid. The atomizing core is provided with positive and negative electrodes for connection with the e-cigarette control circuit. The atomizing core is generally composed of an outer casing and a built-in heating wire. The heating wire is further provided with an e-cigarette liquid capable of permeation, commonly known as e-liquid, and a conducting and storage element, simply referred to as a liquid conducting member or an e-liquid conducting member, such as a liquid conducting cotton or an e-liquid conducting cotton. The top of the atomizer/atomizing chamber is provided with a smoke channel, and the smoke channel communicates with a mouthpiece for vaping. A closed space in the cartridge also stores the e-liquid, and is called an e-liquid storage tank. The e-liquid is adsorbed by the e-liquid conducting cotton, the power source is turned on, the heating wire generates heat, the heating wire atomizes the e-liquid adsorbed to the e-liquid conducting cotton, and the atomized e-liquid flows out through the smoke channel and the mouthpiece.

In addition, the e-cigarette currently used may also include an upper casing and a lower casing. An atomizer is installed in the upper casing, the lower casing corresponding to the main body is provided with a battery and a circuit board, the atomizer includes an outer casing and a base, the outer casing is screwed on an upper portion of the base, the base is provided with an air inlet hole, a side surface of the outer casing is provided with an e-liquid inlet hole, an atomizing core with an e-liquid conducting cotton and a heating wire is installed in the outer casing, the air inlet hole is located below the e-liquid conducting cotton and the heating wire, an upper cover is disposed on the upper casing, the upper cover is provided with a mouthpiece, a smoke passage is disposed in the upper cover, the bottom of the smoke passage is crimped to the top of the outer casing, an upper portion of the smoke passage communicates with the mouthpiece, the upper cover, the smoke passage, the outer casing, the base and the upper casing form an e-liquid storage tank, the e-liquid storage tank stores an e-liquid, and the e-liquid flows into the e-liquid conducting cotton through the e-liquid inlet hole. The power source is turned on, the heating wire starts to generate heat to atomize the e-liquid in the e-liquid conducting cotton, and the atomized smoke flows out along the smoke passage and the mouthpiece.

The e-liquid of these e-cigarettes generally communicates with the outside even when not in use through the e-liquid conducting cotton, the smoke channel and the mouthpiece. Therefore, if the e-cigarette is placed for a long time, the e-liquid stored in the e-liquid storage tank/cartridge will continuously flow into the e-liquid conducting cotton through the e-liquid inlet hole, and the e-liquid accumulated in the e-liquid conducting cotton flows out along the air inlet hole, causing the leakage of the e-liquid. In addition, when the e-cigarette is placed for a long time, the e-liquid is in contact with the air for a long time, and the taste of the e-liquid is also greatly affected. If during the movement, for example, when the e-cigarette is placed in the pocket, the e-liquid is subjected to constant shocks from outside, and is likely to seep out from the smoke channel and the mouthpiece, causing the leakage of the e-liquid. The leaked e-liquid may even contaminate clothes and the like.

In addition, in the e-cigarettes currently used, the main body and the cartridge/atomizing device are fixed and realise circuit connection generally by screws and screw holes, and the connection and fixing manner is a conventional cooperation manner. With the development of e-cigarettes, users have lost interest in this traditional fixing manner. Therefore, it is necessary to design a new-structure e-cigarette to meet the diverse requirements of users.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. It is apparent that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work are within the protection scope of the present invention.

As shown in FIG. 1 to FIG. 8, an atomization generating device of the first embodiment of the present invention provides a liquid-flux—variable atomization generating device, including: a housing 1, in which a slide rail is disposed; an e-liquid storage tank 2, that is, an e-liquid storage portion, movably installed on the slide rail up and down, where the e-liquid storage tank 2 has a first tank body 21 and a second tank body 22 communicating with each other, the second tank body 22 is located below the first tank body 21, a liquid flux is defined as the rate of flow of a liquid across the cross section of the tank body per unit time, and the liquid flux of the first tank body 21 is greater than the liquid flux of the second tank body 22; and an atomizer 3, that is, an atomizing portion, including an atomizing casing 31, where the atomizing casing 31 is sleeved on a rubber plug 32, that is, a sealing portion, the rubber plug 32 is installed in the second tank body 22, an outer wall of the rubber plug 32 abuts against an inner wall of the second tank body 22, the atomizing casing 31 is fixed in the housing 1, the atomizing casing 31 is provided with an e-liquid inlet hole 111, the e-liquid inlet hole 111 is located below the rubber plug 32, and an e-liquid conducting body and a heating element are installed in the atomizing casing 31; Wherein when the e-liquid storage tank 2 is pushed downward, the e-liquid storage tank 2 moves downward along the slide rail, the rubber plug 32 enters the first tank body 21 from the second tank body 22, so that the e-liquid in the first tank body 21 flows into the second tank body 22 through a gap between the first tank body 21 and the rubber plug 32 and then flows into the e-liquid conducting body through the e-liquid inlet hole 111 so as to be atomized by the heating element.

The bottom of the atomizing casing 31 is further provided with a metal electrode, the atomizing casing 31 and the metal electrode are independent of each other through an insulator, and an air inlet hole is disposed in the metal electrode, so that outside air enters the atomizing casing 31 and takes the atomized e-liquid away.

An upper portion of the first tank body 21 is provided with a cover body 4, a smoke channel 41 is installed in the cover body 4, and the smoke channel 41 extends downward into the atomizing casing 31. The cover body 4 can seal the upper portion of the e-liquid storage tank 2 to avoid contact with the outside air. When it is required to inject the e-liquid, the cover body 4 can be taken out, and then the e-liquid is injected into the first tank body 21.

The rubber plug 32 includes a main body portion 121 and a fastening portion 122, a through hole 123 is disposed in the main body portion 121, the smoke channel 41 is inserted into the through hole 123, the fastening portion 122 is snapped to an upper portion of the atomizing casing 31, an upper surface of the main body portion 121 is further provided with a snapping member 34, and the snapping member 34 is sleeved on the periphery of the smoke channel 41. Further sealing and snapping can be performed directly on the main body portion 121 and the smoke channel 41. An inner diameter of the first tank body 21 is greater than an inner diameter of the second tank body 22, a diameter of the main body portion 121 is equal to the inner diameter of the second tank body 22, and an outer diameter of the fastening portion 122 is less than an outer diameter of the main body portion 121. By this design, when the rubber plug 32 moves from below to the first tank body 21 above, the resistance can be reduced, and when the rubber plug 32 is in the first tank body 21, the e-liquid can flow downward. This is due to the fact that when the diameter of the rubber plug 32 is less than the inner diameter of the first tank body 21, the e-liquid flows downward along the gap between the rubber plug 32 and the inner wall of the first tank body 21 into the second tank body 22, so that the e-liquid flows into the atomizing core heating element.

The top of the housing 1 is provided with a mouthpiece 5, the mouthpiece 5 has a smoke outlet channel 51, the smoke outlet channel 51 is sleeved on the periphery of the smoke channel 41, and a lower portion of the smoke outlet channel 51 is snapped to the cover body 4, so that the smoke outlet channel 51 squeezes the cover body 4 and the cover body 4 pushes the e-liquid storage tank 2 to move downward. A fixing portion 33 is disposed inside the housing 1, and the atomizing casing 31 is fixed to the fixing portion 33, thereby preventing the atomizing casing 31 from loosening.

A guiding portion 112 protrudes from a sidewall of the atomizing casing 31, the guiding portion 112 is installed in the second tank body 22, and the guiding portion 112 is parallel to the inner wall surface of the second tank body 22. The cross section of the first tank body 21 has a square shape, the second tank body 22 has a circular shape, and an inner diameter of the first tank body 21 is greater than or equal to an inner diameter of the second tank body 22. The first tank body 21 on the upper side has a square shape, and the second tank body 22 on the lower side has a circular shape. By this design, the e-liquid can flow downward through the gap between the rubber plug 32 and the first tank body 21. Since there is the gap between the square first tank body 21 and the circular rubber stopper 32, even if the inner diameter of the square first tank body 21 is equal to the diameter of the circular rubber plug 32, the circular rubber plug 32 can move up and down in the square first tank body 21. Since the circular rubber plug 32 just abuts against the inner wall of the square first tank body 21 at this time, specifically, in a way of tangency instead of surface contact, a gap exists between the circular rubber plug and the corner of the square first tank body 21, and the e-liquid can enter the second tank body 22 through the gap.

Further, a battery 6 and a circuit board are further installed in the housing 1, the battery 6 is connected to the circuit board, and the circuit board is connected to the heating element.
