## Background
FIELD OF THE INVENTION
The present invention relates to a touch battery, and particularly to a touch battery for an electronic cigarette.
BACKGROUND OF THE INVENTION
At present, electronic cigarettes include key electronic cigarettes or air-switch electronic cigarettes. The keys may be disabled or stuck after long-term use due to limited number of times or man-made damage. When put in clothes, electronic cigarettes may work sometimes if the keys are pressed unconsciously, so there is a certain issue of safety. In operation, it is required to press and hold the keys hard to enable the electronic cigarettes to work.
The rise of capacitive touch technology brings great convenience for people's production and life. Capacitive touch technology refers to that touch detection is performed in a number of lattice points intersected horizontally and vertically and then charge levels at contact points are detected, so that it is determined whether a finger touches a sensing surface by monitoring the small change in capacitance and then information about the position of a touch point is acquired by detecting the change rule of capacitance of the lattice points.
From the composition of capacitive lattice points, capacitive touch includes self-capacitive touch and mutual-capacitive touch.
The structural principle of mutual-capacitive touch is shown in FIG. 5 and FIG. 6. Capacitive lattice points are formed of longitudinal sensing lines and transverse drive lines. The point of intersection of the two lines has mutual capacitance. If a finger of a person approaches to this point, the electric field lines of a part of mutual capacitance will be absorbed because the human body may be equivalent to a potential; equivalently, the mutual capacitance is reduced. If the capacitance of each of the lattice points is scanned continuously, the position touched by a person may be acquired. The mutual capacitance may be formed on a plane, that is, capacitive lattice points may realize mutual-inductance on a single plane, as shown in FIG. 7.
The structural principle of self-capacitive touch is shown in FIG. 8. As the human body may be equivalent to a fixed potential, when the human body gets close to a sensing line, the capacitance of the sensing line to the ground (the human body may be regarded as the ground) will increase, that is, the self-capacitance thereof increases. For example, when a point (X1, Y2) is touched, the capacitances of X1 and Y2 become larger, and therefore the touch position may be determined. By continuously scanning the capacitance of each line to the ground (or a certain fixed potential), a touch coordinate may be determined. However, on an electronic cigarette, the area of a capacitive touch portion is pretty small, and this demand is extremely urgent particularly with a technical development trend of small but excellent at present. It is required to calculate capacitance by software and finally fit it with the structure of the electronic cigarettes to achieve the best touch effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be further described as below with reference to accompanying drawings.
The present invention relates to an electronic cigarette having a single lithium battery cell, characterized by constant-voltage output and touch suction on its bottom. The battery can be triggered to work only by the temperature of a human body rather than touch of the clothes, and the battery thus may be carried around. The conventional way of batteries with keys is avoided, and the demands of consumers for multiple sections are met. The battery is charged in a conventional manner, and has a touch portion on its bottom. The battery starts to work as long as a user touches the bottom lightly with the little finger, and then the user may smoke.
The touch battery includes a short contact member 11, an insulating ring 12, an intermediate threaded connector 13, a PCBA control panel 15, a touch member 17, a tail membrane 18, a battery, a battery pole 19 and a tobacco rod (20). The characteristics and interrelation of the components are as follows: after a finger touches the tail membrane 18 on the bottom of the battery, the battery start to work via the touch member 17, and then an LED indicator on the PCBA control panel 15 will turn on; the PCB bracket 14 plays a role of securing the PCBA; the battery supplies input power for the PCBA control panel 15, and is then connected to the intermediate threaded connector 13 by an output and connected to an atomizer via the short contact member 11, so that smoking is achieved. After 10 seconds of smoking and the LED indicator flickers for 8 times, it is required to touch again for another time of smoking as the battery has functions of locking and unlocking. At the end of smoking, the battery may be put into a pocket and carried around.
With respect to the prior art, during the implementation of the present invention, the capacitive touch member is made into a round metal member. The general principle of the capacitive touch technology is as follows: many capacitive lattice points are formed in a capacitive touch region, and the capacitance of a corresponding capacitive lattice point will change when the capacitive lattice point is touched with a finger, so that touch information may be acquired. However, when the touch area of an electronic cigarette is very small, touching with a finger may cover the whole plane of the touch member. By using the round metal member provided by the present invention as a touch surface, according to the principle of the prior art as shown and the practical structure of an electronic cigarette, it is required to calculate capacitive lattice points on software in advance, so that the touch information may be acquired by a small touch object to trigger the electronic cigarette to work.
In addition, the capacitive touch member may be made into different shapes, for example, round, rhombic, boxed, checkered, or convex-concave. The capacitive lattice points may be distributed in any common manner, as long as such distribution is convenient for capacitance detection.
In addition, when acquiring touch information, the capacitive touch member performs capacitance detection in a self-inductance manner or a mutual-inductance manner. As a result, the capacitance detection manner of the capacitive touch member will not be limited after it has been extended in structure, and the touch detection method is similar to the existing planar touch, so that the capacitance of a capacitive lattice point is determined by experiments, without increasing the difficulty of detection.
In addition, the capacitive touch member further includes a protection structure which covers the capacitive lattice points. The capacitive lattice points may be protected by enclosing the capacitive lattice points inside the PCB bracket of the protection structure, so that external environmental factors may be effectively avoided from influencing the capacitance detection. Consequently, the touch information may be acquired accurately.
In addition, the capacitive touch member is secured inside the PCB bracket and the bottom of the bracket is formed to be a recessed shape. As the surface of a finger is arced, the finger is in better contact with the touch member, so that the touch information may be acquired more accurately.
In addition, as the capacitive touch member is influenced by the structure of the electronic cigarette, the touch member may be disposed on the bottom of an electronic cigarette, in the middle of the electronic cigarette or at the atomizer portion. The above structures may be implemented by the functions of the present invention.
A primary IC control portion of the capacitive touch portion provided by the present invention scans and determines capacitive lattice points of a touch portion via an input mode, so that touch parameters on a touch chip may be flexibly modified and set by the primary IC. During the use of the capacitive touch portion, on account of external environmental factors and the size of the touch capacitive lattice points, the touch parameters and the size of the touch plane are determined by experiments in order to ensure that the electronic cigarette has the best touch effect.
The diaphragm of the PCB bracket and the indicator portion indicate different working states.
When the finger of a user touches the tail of the touch member, the LED indicator keeps on normally, and the diaphragm of the PCB bracket gives out light. Meanwhile, the atomizer emits heat and generates smoke. When the finger leaves the touch member, the indicator will turn off, and the atomizer does not emit heat any more and stops working. When the finger touches the touch member again, the LED indicator keeps on normally.
When the voltage of the battery is greater than 3.8V, a white LED indicator turns on; when the voltage of the battery is 3.5V-3.8V, a blue LED indicator turns on; and when the voltage of the battery is less than or equal to 3.5V, a red LED indicator turns on. Through the three colors of LED indicators, a user knows the current use situation. If the red LED indicator turns on, it is indicated that the battery needs to be charged.
When a finger touches the tail of the touch member and the surface of the membrane and then holds and the time for smoking is greater than 10 s, the current voltage LED indicator of the battery flickers for 8 times to remind of time out. After the LED indicator flickers, the user may continue to smoke.
Smoking after the voltage of the battery is lower than 3.2 V: the red LED flickers for 10 times to remind of charging. Hereafter, smoking cannot be performed when the finger touches the tail of the touch member until the battery is charged by a charger successfully.
LOCK/UNCLOCK: LOCK/UNCLOCK is touched continuously for 5 times within 2 s, then the white, blue and red LED indicators simultaneously flicker for 3 times.
When the battery is connected to a charger, the while, blue and red LEDs simultaneously flicker for 3 times to remind a user that the battery has been connected to the charger well, and the charging to the system is started. During charging, an LED indicator keeps on normally (the red indicator turns on when the voltage of the battery is below 3.5 v, the blue indicator turns on when the voltage of the battery is 3.5 v-3.8 v, and the white indicator turns on when the voltage is greater than 3.8 v). During charging, when the charger is taken off, the white, blue and red LED indicators simultaneously flicker for 3 times.
To meet the operational convenience of different people in turning on/off the battery, bottom touch is designed to meet the demands of consumers. The touch member is connected to the atomizer via the intermediate threaded connector in a contact manner. The atomizer may work once a finger touches the bottom of the battery. The bottom touch is designed to be recessed shape, so that the area contacted by a finger is broad when the finger touches the bottom, the finger thus better contacts with the touch member to enable the battery to work.
The detection is performed by the charge level, at a contact point, of the finger of a user. The finger or the touch member is determined by monitoring the small change in capacitance. When the battery starts to work, the LED indicators at the indicator control portion on the PCBA turn on, and a heating coil connected to the atomizer portion via the threaded touch member generates heat. A series of atomizers in market, for example, CE4, CE8, CE9, etc, may be applicable to this electronic cigarette. The resistance of the heating coil may be 1 Ohm at minimum, so that the worry of numerous consumers that an atomizer having low resistance cannot be applicable to this electronic cigarette is relieved. When a finger touches the touch member, 3.7 v voltage passes through two ends of the heating coil, and the heating coil generates heat to burn tobacco tar. Then, by the airflow produced by the smoking of the user, the smoke generated by burning the tobacco bar is taken out from the inside of the atomizer and then comes out from the cigarette holder. Thus, smoking is realized. When a user does not want to smoke now, the user may let the finger leave the touch member; and when the user wants to smoke later, the user needs to touch the touch member on the bottom. When the time of one smoking exceeds a preset time, the indicator under a corresponding electric quantity will flicker for several times to remind the user of time out; and when the user wants to smoke later, the user needs to touch the touch member on the bottom again. If the user does not want to smoke, the electronic cigarette gets into standby to save power. When the touch member is continuously touched for 5 times, the electronic cigarette gets to be locked. In this case, a user cannot smoke by the electronic cigarette unless the touch member is touched for 5 times again.
The foregoing is further detailed description of the present invention with reference to specific preferred embodiments, and will not be regarded as any limitation to the specific embodiments of the present invention. It will be understood by an ordinary person of kill in the art that the present invention may have various simple deductions or replacements without departing from the idea of the present invention, and those deductions or replacements shall fall into the protection scope of the present invention.
