Referring to FIGS. 1-5, the liquid-liquid controllable electronic cigarette 100 according to the present invention includes a casing 10, a liquid storage tank 30 housed in the casing 10 for storing the liquid smoke, and is disposed in the liquid storage tank 30. A liquid pumping device 800 for withdrawing the liquid smoke in the liquid storage tank 30 and an atomizing device 900 disposed in the outer casing 10 and for atomizing the liquid smoke.

The outer casing 10 includes a bottom wall 12, an annular side wall 14 extending from the bottom wall 12, and a top wall 16 formed on the top of the side wall 14. The annular side wall 14 is provided with a liquid injection port (not labeled) communicating with the liquid storage tank 30, and the liquid injection opening 144 is detachably and sealingly mounted on the liquid injection opening. When the liquid filling cap 144 is pulled out, the liquid smoke can be injected into the liquid storage tank 30 from the outside through the liquid filling port. Preferably, a sealing ring 146 is interposed between the liquid injection cover 144 and the liquid injection port. Opening on the top wall 16 There is a mouthpiece interface 162 on which the mouthpiece fixing tube 600 is mounted, and the end of the fixed tube 600 is provided with a mouthpiece 700. The mouthpiece 700 and the mouthpiece fixing tube 600 are mainly used for guiding the smoke, and also play a decorative role; the appearance of the two can be ergonomic according to the usage habits of the consumer. And the materials of both are generally environmentally friendly plastic materials.

The liquid pumping device 800 includes a pump body 40 that extends into the liquid storage tank 30 and has a passage 41 that communicates with the liquid storage tank 30, a ball valve 42 that is movably disposed in the passage 41 and can only move upward, and is slidably disposed in the passage The hollow piston 46 in the 41, the compression spring 44 between the piston 46 and the ball valve 42, the guide tube 48 mounted on the top of the piston 46 and conducting with the passage 41 (by the hollow structure of the piston 46) and fixing A drain button 164 that projects over the top of the draft tube 48 and projects outwardly from the top wall 16 of the outer casing 10. The draft tube 48 has a bend 482 for transporting the liquid smoke to the atomizing device 900 by means of the bend 482. The liquid suction button 164 is used for pumping liquid, and the material thereof is generally an environmentally friendly plastic material. The guiding tube 48 is used for fixing the liquid suction button 164, and is used for introducing liquid from the pump body 40 to the atomizing rod 50, and the material is generally an environmentally friendly plastic material.

The atomizing device 900 includes a hollow atomizing rod 50, an atomizing duct 52 installed in the atomizing rod 50, a return cup 500 sleeved on the periphery of the top of the atomizing duct 52 and connected to the mouthpiece interface 162, and installed in the mist. An inner copper ring 60 at the bottom of the rod 50, a short contact 70 disposed on the inner copper ring 60 and insulated from the inner copper ring 60 by an insulating ring (not labeled) 80, is disposed on the top of the inner copper ring 60 The long contact member 200 is insulated from the long contact member 200 by an insulating ring (not labeled) and sleeved on the outer copper ring 90 outside the long contact member 200 and the heating wire 92 disposed in the outer copper ring 90. The outer copper ring 90 is simultaneously nested inside the atomizing duct 52.

Further, the housing 10 further has a battery compartment 300 and a circuit board 408 for housing the battery 400. In addition, a power button 142 is further mounted on the side wall 14 of the outer casing 10.

The heating wire 92 is a heat generating device of the product, which is directly in contact with the soot liquid storage cotton, and is turned on at the switch. In the case, the liquid will be atomized directly. It should be noted that: the contact area between the heating wire 92 and the soot liquid storage cotton directly affects the atomization amount and effect, and therefore it generally uses a high temperature resistant alloy heating wire.

The inner and outer copper rings 60, 90 are electrical connection portions and function to connect the main body of the electronic cigarette battery. The combination with the long contact member 200 is the key to the action of the disposable atomizer heating device.

The long and short contacts 200, 70 are mainly electrically conductive, i.e., in contact with the body of the electronic cigarette.

The working process of the smoke liquid controllable electronic cigarette 100 of the present invention will be briefly described below.

1. Injecting liquid: The electronic cigarette 100 is placed upside down, the liquid injection port is turned upward, then the liquid filling cover 144 is removed, and the liquid is injected into the liquid storage tank 30 by a syringe or a drip bottle, and the maximum amount can be injected 5ML at a time;

2. Smoke liquid extraction: Pressing the liquid suction button 164 causes the piston 46 to move downward relative to the pump body 40. As the piston 46 moves, the spring 44 is compressed, and the air above the liquid smoke in the liquid storage tank 30 is Compressed, thereby driving the smoke liquid into the passage 41 of the pump body 40, and then, as the compression spring 44 is restored, the piston 46 moves upward, thereby causing the smoke liquid in the passage 41 to move upward, and the upwardly moving smoke liquid opens the ball valve. 42 is then drawn into the atomizing rod 50 of the atomizing device via the hollow portion of the piston 46 and the draft tube 48 and its bend 482.

3. Working process of the atomizing device: Press the power button 142, the current is turned on, through the inner and outer copper rings, the long and short contacts transmit the current to the heating wire 92, and the heating wire 92 converts the electric energy into heat energy up to about 300 degrees. When the user smokes, the airflow passes through the storage cotton, and the smoke liquid in the storage cotton is transported to the heating wire, so that the smoke liquid is atomized at a high temperature of the heating wire to generate a quantity of smoke to achieve a working effect. Subsequently, the smoke is drawn by the user through the mouthpiece interface 162, the mouthpiece fixing tube 600 and the mouthpiece 700.

The invention has a number of advantages. Firstly, the atomization effect is good, the amount of smoke is the best, and the airflow is more suitable for the electronic cigarette. The consumer can press the pumping button to pump the liquid to the atomizing rod according to the amount of liquid smoke required; Flavored liquid; very convenient; the mouthpiece and mouthpiece fixed tube are detachable, Travel is easy to carry.

In other words, compared with similar products, the amount of smoke is increased, and the atomization effect is more impressive; consumers can refill different liquids with more choices; more liquid can be injected, reducing the number of frequent replacements and injections; The liquid can be pumped to the atomizing rod according to the amount of liquid required; the atomizer is transparent, the consumer can see the work of the whole product, in line with the consumer's psychology; and all the parts of the product are made of environmentally friendly materials.

The above embodiments are preferred embodiments of the present invention, but are not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and scope of the present invention should be Equivalent replacement means are included in the scope of protection of the present invention.
