Abstract: An electronic cigarette includes an inhalation rod with a cavity, a mouthpiece assembly, an e-liquid accommodating assembly and an atomization assembly. The mouthpiece assembly, the e-liquid accommodating assembly and the atomization assembly are installed in the cavity of the inhalation rod. Between the mouthpiece assembly and the atomization assembly disposes a ventilation tube capable to guide the atomized e-liquid from the atomization assembly to the mouthpiece assembly. The mouthpiece assembly includes a filter. On an inner wall of the cavity of the inhalation rod along the axial direction thereof disposes a first mounting part. The filter or on other components fixing connected with the filter disposes a second mounting part. The first mounting part and the second mounting part are disposed adjacent to each other. The connection by mechanical mechanism does not need to use glue or other adhesive containing harmful ingredients.

Abstract: A protective device and method for preventing supply voltage of microcontroller from sag in electronic cigarette is provided, comprising a microcontroller, a power supply module, a field effect transistor, an energy storage circuit, wherein, the energy storage circuit is connected between the microcontroller and the power supply module, the energy storage circuit supplies electric power to the microcontroller when an over current or short circuit occurs, and maintains the supply voltage of the microcontroller not being less than its minimal operating voltage in a certain period of time; the microcontroller processes the over current or short circuit signal and turns off the MOSFET to cut off the current flow in a load circuit. The unstable or uncontrollable phenomena of the microcontroller in the existing technology are resolved. The circuit of the present invention is simple and low cost.

Abstract: A wireless charging device comprises an electronic switch and a transmitting coil (L1) electrically connected with a power source in sequence. A control end of the electronic switch is connected with a transmitting control unit. The wireless charging device further comprises a current limiting resistance (R1) connected in serial with the transmitting coil. The wireless charging device further comprises a compensation capacitor (C1) connected in parallel with the transmitting coil. An insert total electromagnetic coupling structure is further employed for charging. Such wireless charging device is particularly suitable for electronic cigarette, with low cost, stable and reliable working status and high efficiency, and specific heat sink is not required.

Abstract: This invention relates to an electronic cigarette device, including an electronic cigarette and an electronic cigarette charger, the electronic cigarette charger forming a first magnetic portion, the electronic cigarette correspondingly forming a second magnetic portion mutually magnetically adsorbed with the first magnetic portion. The electronic cigarette charger forms a first connector, and the first connector comprises a first seat, a first electrode pole disposed at a middle portion of the first seat and a first insulating sleeve disposed between the first seat and the first electrode pole to insulate the first seat and the first electrode pole. The electronic cigarette forms an electronic cigarette battery therein, and the electronic cigarette at an end thereof forms a second connector connected with the electronic cigarette battery and the first connector of the electronic cigarette charger.

Abstract: An electronic cigarette box is provided, comprising a box body, a box cover connected with the box body, an electronic cigarette container received in the box body, wherein, the box body defines a holding cavity, a bottle is received in the holding cavity, and the bottle contains perfume, air fresheners, deodorant or medicine. When the electronic cigarette box generates peculiar smell after a long time of use, a user can spray appropriate perfume into the electronic cigarette box to dispel the peculiar smell; the body of the user may have residual smoke smell when he/she has smoked the electronic cigarette a short time ago, the user can take out the perfume bottle and spray some perfume onto his/her body, thereby burnishing the user's image and improving the user's experience; the bottle can also received medicine, the user can be treated timely when feeling uncomfortable or illness due to smoking.
