Abstract: An electronic cigarette vaporizer comprises an outer tube, a mouthpiece member arranged at an end of the outer tube, and a vaporizing member arranged inside the outer tube. The vaporizing member comprises a two-part tube body which is integrally-formed and consists of a vapor tube located at an upper position and having a smaller diameter and a vaporizing tube located at a lower position and having a greater diameter which are connected with each other. A storage chamber for storing vapor substrate is formed between an outer wall of the two-part tube body and an inner wall of the outer tube. A tube-shaped vaporizing core for heating and vaporizing the vapor substrate is sleeved inside the vaporizing tube. A wall portion of the vaporizing tube is provided with a substrate through-hole. An upper end of a wall portion of the vapor tube is provided with a vent aperture.

Abstract: The invention relates to an electronic cigarette equipped with double air pressure sensors and a control method thereof. Herein, the vaporizer of the electronic cigarette comprises a heating member, wherein a heating resistor is disposed in the heating member, and a battery, a control circuit board and an intake passage are disposed in the battery stick. The control circuit board is arranged with a micro-controlled switch, a microcontroller and a power adjustment module. Double air pressure sensors are disposed in the intake passage, including a switching air pressure sensor for detecting the suction force and determine whether the suction force reaches a switching value to switch on or off the micro-controlled switch, and a digital air pressure sensor for detecting the magnitude of the suction force during the working of the heating resistor to allow controlling of the amount of the vapor.

Abstract: An electronic cigarette vaporizer comprises a housing and a bottom cap, and a vaporizing base, a vaporizing unit and a vaporizing cover part arranged within the housing. The vaporizing base is provided in a center with a rectangular groove. The vaporizing unit comprises a liquid guiding strip and a heating coil wound around a middle portion of the liquid guiding strip. The liquid guiding strip is transversely arranged above the rectangular groove. The vaporizing cover part is arranged on the vaporizing base. A vaporizing chamber is defined between the lower portion of the vaporizing cover part and the vaporizing base. The upper portion of the vaporizing cover part is provided with a conical tube with an inner diameter increasing downwardly. The upper end of the conical tube is sleeved within the inner conical tube. The mouthpiece hole is in communication with the vaporizing chamber by the conical tube.

Abstract: An electronic cigarette with a vaporizer having dual cavities and dual air passages comprises a vaporizer and a battery rod which are detachably connected, wherein the vaporizer comprises a housing and a vaporizing device. A partitioning portion divides the inner cavity of the housing into a large cavity and a small cavity. A first air outlet pipe provided in the small cavity, an air outlet through-hole provided in the vaporizing device and a second air outlet pipe provided in the battery rod are connected in sequence to form a suction sensing air passage. The air intake hole, the air inlet passage, the air inlet cavity, vaporizing chamber, the vapor tube and the vapor outlet hole which are arranged in the housing are connected in sequence to form a smoking air passage.

Abstract: The disclosure provides an automatically controlled heat-not-burn electronic cigarette device and a control method thereof. The electronic cigarette device comprises a housing, a housing lid and a heating tube arranged in the housing, a heat-insulating tube, an automatic lid opening and/or closing mechanism, a cigarette detecting mechanism, an intelligent control circuit board, a button, and a battery. The intelligent control circuit board is arranged with a main control chip, a heating control module, an automatic lid opening and/or closing control module, a button control module, a detector control module, and a charging management module. The main control chip is configured to control the electronic cigarette device to enter a smoking operation mode, or a sleep state, or an off state, on the basis of the determination of whether a cigarette is received in the heating tube within a certain time.
