[0039] The following embodiments are used to explain the technical solution of this utility model in a non-limiting manner.
[0040] Example 1
[0041] like Figures 1-3 The electronic cigarette cartridge shown includes a cartridge shell 9, a cartridge middle cover 8, and a cartridge bottom cover 5, which are fitted together by conventional limiting mechanisms such as a latch and a slot. The cartridge middle cover 8 and the cartridge bottom cover 5 are made of heat-resistant silicone, and the cartridge shell 9 is made of food-grade PC material.
[0042] The cartridge shell 9 is constructed with a smoke outlet 92 at the top and a shell body 91 around the perimeter. A smoke pipe 93 is installed inside the shell body 91 and connected to the smoke outlet 92. The length of the smoke pipe 93 is such that its lower end abuts against the upper surface of the cartridge cover 8.
[0043] The cartridge inner cover 8 and the cartridge bottom cover 5 can be assembled together. In this configuration, the space between the inner cover 8 and the bottom cover 5 forms an atomizer carrier cavity 102, used to house the atomizer carrier 7. In addition to housing the atomizer carrier 7, the cartridge inner cover 8 has a smoke hole 81 for connecting the atomizer carrier cavity 102 to the smoke tube 93. The cartridge inner cover 8 also has a small oil filling hole 82, allowing consumers to easily fill the atomizer carrier cavity 102 with liquid atomized material through the oil filling hole 82.
[0044] The bottom cover 54 of the cartridge has a hole 53 in the middle, and a heat conductor 6 is installed in the hole 53, so that the metal heat conductor 6 is part of the bottom cover 5 of the cartridge. In this way, when the heat conductor heats up, the atomizing carrier 7 in contact with it is heated.
[0045] The atomizing carrier 7 is made of folded oil-absorbing cotton and is filled in the atomizing carrier cavity 102.
[0046] Electronic cigarette systems such as Figures 4-6 As shown, the device includes a standard electronic cigarette casing 103, a bracket 104, a battery, and a control board. A position for mounting the ferrite cartridge 2 and ferrite cartridge cover 4 is provided on the upper part of the bracket 104. The ferrite cartridge 2 has an air inlet 21 and a pin hole 22 at its bottom, and the ferrite cartridge cover 4 has an air outlet 41. The coil 3 is placed in the ferrite cartridge 2, with its pins extending from the pin hole 22 and connecting to the control board. Furthermore, a position for fixing the airflow sensor 1 is provided on the bracket 104. The airflow sensor 1 is positioned near the air inlet 21 and electrically connected to the control board, serving as a switch for the electronic cigarette coil.
[0047] like Figure 7 As shown, when the cartridge is used with the electronic cigarette system, the metal heat conductor 6 is adjacent to the upper surface of the ferrite box cover 4.
[0048] In use, when the consumer inhales from the smoke outlet, air enters the electronic cigarette through the air inlet 105 and flows past the airflow sensor 1. The airflow sensor 1 converts the airflow into an electrical signal, driving the electronic control board to input current to the coil. This generates a high-frequency alternating magnetic field inside the coil, causing the metal heat conductor to heat up. Consequently, the atomized material on the atomizer carrier 7, which is in contact with the heat conductor, is heated, atomized, and produces vapor, which fills the atomizer carrier cavity 102.
[0049] On the other hand, as the inhalation action occurs, air enters the air intake duct 52 through the air inlet 21 and the air outlet 41, then enters the atomized carrier cavity 102 and mixes with the atomized vapor to form an aerosol, which enters the flue pipe 93 through the flue vent 81, and is finally inhaled by the consumer from the flue outlet 92.
