Description

Electronic cigarette with breath sensing function

This creation relates to an electronic cigarette, in particular to an electronic cigarette with breath sensing function.

Unlike traditional tobacco that needs to be ignited by an open flame, an electronic cigarette is a heat-generating and non-burning device. It uses an electric heating element to heat the chemically-treated tobacco or essential oil, so that it releases smoke particles and is absorbed by people, thus achieving The same thrill of smoking traditional tobacco. Among them, for electronic cigarettes that use e-liquid as the heating object, for the convenience of users, most of them are now equipped with breathing sensors. When the user has a smoking action, the electronic cigarette automatically turns on the power and starts working. When there is no smoking for a long time When in action, the electronic cigarette automatically turns off the power, which not only saves the trouble of operating the power switch every time it is turned on, but also avoids the embarrassment of the electronic cigarette burning for a long time because of forgetting to turn off the power switch. However, for this kind of electronic cigarette, the first guarantee is that the smoke oil cannot leak out. Therefore, the oil tank and the power supply tank are sealed, and the breathing sensor and the oil tank are arranged in parallel on the upper end of the electronic cigarette. As a result, the upper end of the e-cigarette is wide and the lower end is small, and the overall structure is not light enough. As a portable appliance, the overall size of the electronic cigarette is light and coordinated. The user pays more attention to it. Therefore, the e-cigarette must be sealed and smoked. Improve the installation location of the measuring sensor.

The purpose of this creation is to provide an electronic cigarette with breath sensing function that can ensure that the e-cigarette smoke oil does not leak and can make the overall size of the e-cigarette light and coordinated.

In order to achieve the above purpose, the present disclosure discloses an electronic cigarette with a breath sensing function, which includes a mouthpiece section, an atomizing section and a cigarette rod section; the mouthpiece section is used to provide a suction nozzle; the cigarette rod section includes a first cylinder, The first cylinder body is used for accommodating a power source, and the first cylinder body is provided with an airflow sensor arranged along the longitudinal direction of the power source; the atomizing section includes a second cylinder body, a smoke pipe, and an atomizer; One end of the second cylinder is hermetically connected to the mouthpiece section, the other end of the second cylinder is hermetically connected to the first cylinder, the smoke duct is threaded through the second cylinder, the The second cylinder is used for containing smoke oil, the atomizer is installed at the lower end of the smoke pipe, and the smoke pipe is provided with an oil inlet channel communicating with the atomizer, the atomizer Is controlled by the airflow sensor, the bottom end of the atomizer is provided with a waterproof and breathable membrane that is sealingly connected to the inner wall of the smoke pipe, through the waterproof and breathable membrane, the mouthpiece section, the A communication airflow channel is formed between the smoke duct and the first cylinder.

The bottom end of the atomizer 22 is provided with a waterproof and breathable membrane 24 which is sealingly connected to the inner wall of the smoke duct 21, and through the waterproof and breathable membrane 24, a continuous air flow is formed between the mouthpiece section 1, the smoke duct 21 and the first cylinder 30 The channel allows the suction airflow to act on the airflow sensor 32. The waterproof breathable membrane 24 prevents the liquid smoke oil in the smoke oil bin 23 from passing, but the airflow can pass therethrough. Through the installation of the waterproof and breathable membrane 24, the problem of leakage of smoke oil is solved, and the problem of air flow from the smoke pipe 21 to the first cylinder 30 is also solved. In order to facilitate the user to observe the amount of smoke oil in the smoke oil tank 23, the second cylinder 20 is made of transparent glass.

The following describes the structural principle of the electronic cigarette with breath sensing function created by the suction air flow and the flow process of smoke particles (generated by the atomizer 22): as shown in the second and third figures, when the cigarette holder section 1 When a suction action is applied, a negative pressure channel is formed between the smoke duct 21 and the first cylinder 30 through the waterproof and breathable membrane 24, so that the suction airflow passes through the waterproof and breathable membrane from the bottom end of the first cylinder 30 24 flows into the atomizer 22 and the smoke duct 21, and finally enters the mouthpiece section 1 through the smoke duct 21, forming a clear air flow channel, the suction air flow acts on the air flow sensor 32, so that the air flow sensor 32 is triggered, thereby turning on the mist The power path of the atomizer 22, the atomizer 22 starts to work, and the smoke particles generated by the atomizer 22 enter the mouthpiece section 1 through the smoke pipe 21 and are sucked into the mouth of a person. It can be seen that the above-mentioned electronic cigarette with breath sensing function not only realizes the function of automatically turning on the power supply 31 through the suction action, but also the airflow sensor 32 and the second cylinder 20 containing the smoke oil are arranged in a longitudinally separated direction, In the atomizing section 2 located in the middle of the electronic cigarette, it is no longer necessary to provide a separate installation structure for the airflow sensor 32, so that the overall structure of the electronic cigarette is relatively light, coordinated up and down, and can also prevent the leakage of smoke oil.
