The present application relates to the field of elec flowing into the airflow path; the air flows backwards the tronic products, and more particularly to an electronic ciga mouthpiece when blowing into the electronic cigarette from rette and a method for adjusting flow rate of gas flow of the the mouthpiece, a pressure inside the electronic cigarette is electronic cigarette. lower than the atmospheric pressure outside, and the airflow pathis sealed up by the floating sphere to avoid the tobacco oil BACKGROUND inside the atomizer flowing to the battery of the cigarette rod. 0002 With a rising attention to health, people come to 0007. In the electronic cigarette of the present application, realize the tobacco is harmful to health, thus the electronic a holding cavity is defined inside the cigarette rod and the cigarette which is both able to ease a craving for tobacco and battery is accommodated in the holding cavity, a Smoke cavity less harmful to health is produced. The electronic cigarette is is defined inside the atomizer and the tobacco oil is contained usually configured to atomize specially prepared tobacco oil in the Smoke cavity, and the holding cavity and the Smoke and simulate tastes of Smoking. When preparing the tobacco cavity are connected to form the airflow path; and the floating oil, materials harmful to health, such as nicotine, tar and the sphere open or close the airflow path according to an airflow like, are removed to eliminate the harm to health. As the direction inside the electronic cigarette and a pressure differ tobacco oil contains no harmful material that makes people be ence between the pressures inside and outside the electronic addicted, such as nicotine, tar and the like, the nicotine addic cigarette, so that the holding cavity and the Smoke cavity are tion will be reduced after Smoking the electronic cigarette. correspondingly communicated or isolated. Therefore, the electronic cigarette has an effect on assisting in 0008. In the electronic cigarette of the present application, quitting Smoking. the pressure regulating valve unit is arranged between the 0003. In the prior art, the electronic cigarette consists of a cigarette rod and the atomizer, the electronic cigarette further cigarette rod, an atomizer and a mouthpiece. A battery is comprises a first bracket and a second bracket, one end of the arranged in the cigarette rod. The tobacco oil is stored in the pressure regulating valve unit is adapted to and fixed on the atomizer. An intake hole connected to the outside is defined first bracket, and the other end of the pressure regulating valve on the cigarette rod or an end of the cigarette rod to enable the unit is adapted to and fixed on the second bracket. air outside to flow into the electronic cigarette. However, the 0009. In the electronic cigarette of the present application, airflow rate flowing into the electronic cigarette is fixed the pressure regulating valve unit includes a valve gland and because the diameter of the intake hole is fixed, and it is a Support base, and a through hole is defined at the top of the difficult to adjust the amount of Smoke by adjusting the air valve gland, the two ends of the Support base are open ends flow rate. In addition, the tobacco oil in the atomizer will be and a plurality of protrusions are spaced on an inner wall of blew into the cigarette rod if users blow into the mouthpiece the Support base, and the floating sphere is movably clamped by mistake when using the electronic cigarette, which will in the protrusions defined on the inner wall of the support render the battery and related connection circuits to be dam base. aged by the tobacco oil. 0010. In the electronic cigarette of the present application, the pressure regulating valve unit further includes a valve BRIEF SUMMARY gland and a Support base, and a through hole is defined at the 0004 Aiming at the drawbacks in the prior art that it is top of the valve gland, an intake hole configured to enable the difficult to adjust flow rate of gas flow of the electronic ciga air outside to flow in and a pilot hole communicated with the rette and it is easy to cause the leakage of the tobacco oil, an intake hole are formed inside the support base, and the pilot objective of the present application is to provide an electronic hole is extended and radially enlarged from the intake hole to cigarette and a method for adjusting flow rate of gas flow of one side that is close to the valve gland, and the floating the electronic cigarette. A pressure regulating valve is used to sphere is movably abutted against the intake hole under the improve tastes of smoke effectively and adjust the airflow rate guidance of the pilot hole to seal up or open the airflow path. by a puffing force. Furthermore, it can avoid the tobacco oil 0011. In the electronic cigarette of the present application, inside a mouthpiece or inside an atomizer flowing into a a circular hole is formed inside the Support base, and the cigarette rod when users blowing at the mouthpiece. circular hole extends from the pilot hole to one side that is 0005. The technical solution of the present application to away from the intake hole, and the intake hole, the pilot hole Solve the technical problem is providing an electronic ciga and the circular hole are arranged with the same axis. rette comprising a cigarette rod with a battery, an atomizer 0012. In the electronic cigarette of the present application, configured to atomize tobacco oil contained therein, and an a centerline of the floating sphere and that of the intake hole airflow path configured to enable the air to flow into the are coaxially arranged, and a diameter of the floating sphere is atomizer, a pressure regulating valve unit is arranged in the larger than a diameter of the intake hole. airflow path, and the pressure regulating valve unit includes a 0013. In the electronic cigarette of the present application, floating sphere configured to close or open the airflow path the floating sphere is clamped at a connection between the according to an airflow direction and to adjust an airflow rate intake hole and the pilot hole to seal up the intake hole. flowing into the airflow path. 0014. In the electronic cigarette of the present application, 0006. In the electronic cigarette of the present application, a Support part and at least two transition parts are defined on the electronic cigarette further comprises a mouthpiece an inner wall of the Support base, and the intake hole is arranged at one side of the atomizer and the side of the defined in the center of the support part, and the at least two US 2015/0351457 A1 Dec. 10, 2015 transition parts extend along the intake hole and are evenly lifetime of the electronic cigarette. Furthermore, the adjusting spaced, the at least two transition parts are enclosed to form method is easy to complete, there is no need to operate manu the pilot hole.
