FIELD OF THE INVENTION

The invention relates to an electronic cigarette and a method for assembling atomizer thereof

BACKGROUND OF THE INVENTION

An electronic cigarette is a simulated cigarette in which substance containing essence is atomized due to heating of an electric heating wire thus resulting in smoke to be inhaled by a user. Please refer toFIG. 1andFIG. 2, assembling process of existing electronic cigarette atomizer is: first winding electric heating wire on a glass fiber wire1, cutting the electric heating wire at a predetermined length, then guiding the glass fiber wire1wound with electric heating wire through a first venting tube2with openings, subsequently sleeving a second venting tube3on the outside of the first venting tube2to abut tightly against the glass fiber wire1so as to prevent the electric heating wire from loosing, and riveting the both ends of the electric heating wire and an electronic wire, finally coating with non-woven cloth, oil-storage medium etc.

However, when the electric heating wire is guided through the venting tube opening, adjacent two cycles are pushed and readily contact to cause the resistance of the electric heating wire to decrease, which reduces the service life of the electronic cigarette and affects the quality consistency of the electronic cigarette with other electronic cigarettes; moreover, the glass fiber wire1is easy to break due to force when being guided through the through hole. Accordingly, the existing electronic cigarette atomizer engages: complicated assembly process, low efficiency, prone to poor product and waste of human and material resources.

SUMMARY OF THE INVENTION

In view of this, the present invention provides an electronic cigarette and an assembling method for atomizer thereof, with simple assembly process, high efficiency, stable quality and saving of human and material costs.

To achieve the above object, the present invention provides an electronic cigarette including a sucking rod and a power rod, wherein the sucking rod includes a sucking cylinder and an atomizer provided in the sucking cylinder and used for producing smoke, the atomizer includes a venting tube and a heating component, the venting tube is radially provided with a through hole for accommodating and fixing the heating component, the venting tube is also provided with a cut thereon which is communicating to the through hole at bottom and used for assembling the heating component. Specifically, the through hole is a round hole without apparent sharp angles, which is not likely to break when being pulled to open from the cut which is communicating to the through hole at bottom. In conclusion, via the cut of the opening in the venting tube, the venting tube can be pulled to open and bended smoothly, so that the heating component can be placed in conveniently and quickly; in addition, relative to the straight groove of the horizontal opening, after the cut of the present embodiment is pulled to open the opening upward faces to the operating person, which facilitates the operating person to place in the heating component from the view point of human-mechanics and accelerates assembly speed.

Furthermore, the cross section of the cut axially cut along the venting tube is shaped as an oblique line.

Furthermore, the cross section of the cut axially cut along the venting tube is shaped as an obtuse-angle broken line.

Furthermore, the cross section of the cut axially cut along the venting tube is shaped as a right-angle broken line.

Furthermore, the corner of the cut is formed with a smooth chamfer angle. Thus, the way of setting the chamfer angle reduces the friction resistance when installing the heating component, and further facilitates a rapid assembly.

Furthermore, the venting tube is a glass fiber tube, cotton fiber tube or soft rubber tube.

Furthermore, the width of the cut is smaller than the diameter of the through hole, thus the cut-away material of the cut is relative less, which is more beneficial for remaining the original status of the venting tube, and remaining the gripping and fixing of the heating component well after assembly is accomplished.

Furthermore, the sucking rod further includes a mouthpiece cover disposed on one end of the sucking cylinder, and a first connector disposed on the other end of the sucking cylinder and used for connecting with the power rod.

Furthermore, the power rod includes a power cylinder and a power source provided in the power cylinder, one end of the power cylinder is provided with a second connector matching with the first connector and the other end is provided with a switch module and a lamp-cap component.

Furthermore, the first connector and the second connector are both composed of an outer electrode ring, an insulating ring and an inner electrode sleeved in sequence.

Furthermore, the atomizer includes an atomization cavity composed of a liquid-storage member, a liquid guiding member and a venting tube sleeved in sequence and closed at both ends, the heating component is disposed in the atomization cavity; wherein, the two ends of the atomization cavity are closed by the mouthpiece cover and the outer electrode ring respectively.

In addition, the invention also provides an assembly method based on the above electronic cigarette atomizer, which includes: an installing step: pulling to open the venting tube in order to enlarge the cut, and installing the heating component along the cut, and; a returning step: loosing the venting tube to make the cut return and accommodate to fix the heating component. Thus, relative to the multi-step assembly of existing electronic cigarettes which requires two venting tubes, the assembly method of the atomizer in the present embodiment only employs one venting tube, and only one time of pulling to open and loosing is enough to accomplish the assembly. The method benefits simple and quick assembly, unlikely to damage the heating component, ensuring the quality, stable quality and saving of human and material costs.

Furthermore, prior to the installing step further included is: a preparing step: on the venting tube disposing a through hole and disposing a cut communicating to the through hole at bottom. Specifically, it can be done by punching a hole and cut a groove on the venting tube with a punching die. The through hole is radially provided along the venting tube, and the diameter thereof matches with the diameter of the heating component.

Furthermore, after the returning step further included is: a wire connecting step: riveting the both ends of the electric heating wire with a metal tube. Specifically, the electronic cigarettes of embodiments in the present invention are divided into two types: one is disposable electronic cigarette, that is, an integrated structure with a sucking rod and a power rod being both disposable and connecting to each other, the two ends of the electric heating wire are riveted respectively to a copper tube bearing conducting wires, specifically the electric heating wire is guided into the tube opening and fixed in the copper tube, and then one conducting wire is welded to a battery after passing through an integrated microphone switch (that is, a switch module), the other conducting wire is welded directly to the battery; the other type is multiple use electronic cigarette, that is, a multiple use power rod is engaged to a sucking rod provided with a disposable atomizer, the power source can be used repeatedly, and the sucking rod can be changed promptly after using, the two ends of the electric heating wire are riveted respectively to a copper tube bearing conducting wires, specifically are guided into the tube opening and fixed in the copper tube, then the conducting wires are separately pressed tightly or welded on the inner and outer electrodes.

The advantages of the electronic cigarette of the present invention and the assembly of the atomizer thereof are that: by employing the technical means of providing a cut on the venting tube which is communicating to the through hole at bottom and used for installing the heating component, technical effects of simple assembly, high efficiency, stable quality and saving of human and material costs are thus achieved.
