Description

 Electronic cigarette and nozzle cover thereof

 [0001] The present invention relates to the field of electronic cigarettes, and more particularly to an electronic cigarette and a nozzle cover provided with a novel air intake method.

Background technique

[0002] As people's attention to physical health rises, people are aware of the harm of tobacco to the body, thus producing an electronic cigarette that is a substitute for tobacco cigarettes. E-cigarettes usually use the atomized liquid to be atomized by the atomizer for use by the user. Since the smoke liquid removes substances harmful to the body such as nicotine and tar during the production process, the harm to the user's body is greatly reduced, also because There is no such thing as nicotine, tar and other harmful substances in the smoke liquid. After smoking the electronic cigarette, people's dependence on smoking will gradually become smaller, so the electronic cigarette also has the effect of assisting smoking cessation.

[0003] As shown in FIG. 1 and FIG. 2, the conventional electronic cigarette includes: a liquid smoke cup, an atomizer, an atomizer control circuit board 111, and a battery 109. The foregoing components are all disposed on the tobacco rod cover 110. Inside.

 [0004] The atomizer is used for atomizing the liquid smoke in the liquid smoke cup into a smoke, the atomizer comprising a heating wire 106 and a liquid guiding core 107 for absorbing the liquid smoke and supporting the electric heating wire, the electric heating wire The 106 is wound around the liquid guiding core 107, and the two ends of the heating wire 106 are respectively connected to the two ends of the battery 109 through electron wires.

[0005] The liquid liquid cup includes a liquid storage part 102 for charging liquid, a liquid guiding tube 103 for guiding the liquid medicine from the liquid storage unit, an air guiding tube 104, a nozzle cover 101, and an atomizing seat 108. The atomizing base 108 and the nozzle cover 101 are oppositely disposed and spaced apart from each other, and the air guiding tube 104 is fixed between the atomizing base 108 and the nozzle cover 101.

The air guiding tube 104 is provided with a card slot 105 extending through the wall of the tube for supporting and fixing the liquid guiding core 107. The liquid guiding core 107 spans the inner ends of the air guiding tube 104. They pass through the card slot 105 and collide with the liquid guiding tube 103 to absorb the liquid smoke to atomize the heating wire. The air guiding tube is used for supporting the liquid storage component, and is used for controlling the height of the liquid medicine cup and supporting the liquid guiding core 107, and is also used as the smoke generated by the atomization of the atomizing liquid to the outside of the tobacco rod sleeve 110. aisle.

[0006] Referring to FIG. 3~5, the electronic cigarette of the structure is mainly ventilated at the center of the nozzle cover 101 by a circular hole 112, and the air guiding tube 104 of the atomizer portion is also located at the center, so that the smoke liquid is in the heating wire. After 106 atomization, the linear type enters the user's mouth. When the atomization temperature is high, the mouth is very irritating. In addition, after the atomization of the oil, it may condense into droplets, which is easy to get from the nozzle cover 101. The central circular hole 112 enters the user's mouth, making the user feel uncomfortable and also causing adverse health effects.
