The gas-liquid separation unit 3 adopts a cyclone separation principle, namely under negative pressure formed by suction, aerosol after the tobacco tar atomization enters a spiral hollow pore channel 3.1 of the gas-liquid separation unit 3 and moves spirally upwards from a lower end inlet hole 3.3 to an upper end outlet hole 3.2, the aerosol spirally rises to enter the upper part of the hollow pore channel 3.1, and large-particle-size liquid particles in the aerosol are thrown to the inner wall surface of the lower part of the hollow pore channel 3.1 under the action of inertial centrifugal force and flow into the tobacco tar soft capsule cartridge 4 from the lower end inlet hole 3.3; the gas or small-particle-size liquid in the aerosol becomes an ascending inner layer rotational flow, and flows into the cavity of the vapor mixing chamber 2 from the hollow thin tube 2.3 of the vapor mixing chamber 2. Because the rotating diameter of the gas or small-particle-size liquid is very small, a strong centrifugal force field still exists under the conditions of small gas flow and low gas flow rate, and the gas-liquid separation effect is ensured, so that the condensed smoke oil liquid is prevented from flowing into the suction port end 1 and being sucked into the suction port.
The electronic cigarette is also provided with a segmented heating control unit which is positioned in the heating needle accommodating cavity 5 and is used for controlling the heating of each hollow tubular insulating segment 113 of the heating needle 5.1. The segmented heating control unit includes a control circuit board 121 and corresponding connection wires. The control circuit board 121 has a function of controlling the electrical connection of each section of metal heating wire to be turned on and off, and can be provided with a temperature setting function. The segmented heating control operation can be performed by a display screen 122 provided on the outer wall of the housing of the electronic cigarette, for example, on the outer wall of the heating pin accommodating chamber 5. The display screen can select the metal heating wires to be controlled, and the heating temperature of each section of metal heating wire is set. After the heating needle 5.1 punctures the tobacco tar soft capsule 4.1, the sectional heating control unit is adopted to start the metal heating wire 114 in the shell of the tobacco tar soft capsule 4.1 to work, and then the number of the working metal heating wires 114 is selectively increased or reduced according to the liquid level of the tobacco tar after the capsule shell is melted, so that the working metal heating wires 114 are ensured to be immersed in the tobacco tar. When the operating metal heating wire 114 heats the soot, other metal heating wires 114 not in contact with the soot are in an off state and do not operate. In the process of smoking, when the tobacco tar is gradually consumed, the liquid level of the tobacco tar is lowered, and the metal heating wire 114 exposed on the liquid level of the tobacco tar can be timely turned off, so that the metal heating wire 114 is prevented from being burnt. A temperature control element can be added in the heating needle accommodating cavity or integrated on the segmented heating control unit to further control the heating temperature of each segment of the metal heating wire 114.
The heating needle expansion and contraction control assembly in the heating needle accommodating cavity 5 comprises a sliding rod 115 fixed at the bottom end of the heating needle accommodating cavity 5 and sleeved with the heating needle 5.1, a pull wire 118, a small ring 119 arranged on the outer wall of the bottom end of the sliding rod 115, a first spring 124 with two ends respectively fixed between the inner wall of the top end of the heating needle 5.1 and the top of the sliding rod 115, a sliding block 120 arranged on the outer wall of the shell of the heating needle accommodating cavity 5 and a sliding groove 123 for the sliding block 120 to slide; one end of the pull wire 118 is connected with the inner wall of the top end of the heating needle 5.1, and the other end of the pull wire penetrates through the small ring 119 and then is connected with the sliding block 120; when the slide block 120 moves to the lowest position of the slide groove 123, the heating needle 5.1 is fully extended, and the first spring 124 is in a relaxed state, and when the slide block 120 moves upward along the slide groove 123, the heating needle 5.1 is contracted, and the first spring 124 is in a compressed state. The slide block 120 moves up and down along the slide groove 123, so that the pull wire 118 can be pulled and the heating needle 5.1 can be pulled to do telescopic movement, when the slide block 120 moves up along the slide groove 123, the pull wire 118 pulls the top end of the heating needle 5.1 to move downwards, the heating needle 5.1 contracts, and the first spring 124 is in a compressed state; when the slide block 120 moves downwards, the pull wire and the first spring both relax, and the heating needle 5.1 extends. When the heating needle 5.1 is extended into the tobacco tar soft capsule cartridge 4 or retracted into the heating needle receiving chamber 5, it can be fixed in the slide groove 123 by the slider 120, so that the heating needle 5.1 remains stationary. The small ring 119 and the pull wire 118 are made of insulating high-temperature resistant materials, and the pull wire has certain tensile strength and elasticity.
A third small hole 116 is formed in the side wall of the hollow tubular insulating section 113 at the lowermost end of the heating needle 5.1, and an elastic protrusion 117 capable of being clamped with the third small hole 116 is arranged on the side wall of the bottom end of the sliding rod 115. The purpose of this arrangement is to clamp the heating pin 5.1 on the bottom end of the sliding bar 115 by the engagement of the third small hole 116 and the elastic projection 117 to define the position of the heating pin 5.1 in the heating pin accommodating chamber 5.
The opening structure 4.2 in the tobacco tar soft capsule cartridge 4 comprises two groups of grooves 103 on the same horizontal line and two sliding pieces which are respectively clamped in one group of grooves 103 and can horizontally slide along the grooves, wherein a first sliding piece 1041 is provided with a clamping hole 106 and a clamping groove 105 which are connected into a whole and are parallel to the grooves 103, and a second sliding piece 1042 is provided with a clamping pin 107 which can be clamped with the clamping groove 105 and a clamping nail 108 which can be clamped with the clamping hole 106; a second spring 125 is disposed between the first sliding piece 1041 and the second sliding piece 1042 and the groove 103 below the first sliding piece and the second sliding piece, and the second spring 125 can urge the two sliding pieces to be clamped. When the heating needle 5.1 is inserted into the tobacco tar soft capsule cartridge 4, the needle point of the heating needle 5.1 jacks up two sliding sheets, and the two sliding sheets respectively slide to the periphery along the grooves on the two sides; when the heating pin 5.1 is retracted to the heating pin accommodating cavity 5 or pulled out from the tobacco tar soft capsule cartridge 4, the two sliding sheets slide to the center along the grooves on the two sides, the clamping pin 107 and the clamping nail 108 on the second sliding sheet 1042 are inserted into the clamping groove 105 and the clamping hole 106 of the first sliding sheet 1041, so that the bottom of the tobacco tar soft capsule cartridge 4 is sealed, and the tobacco tar is prevented from leaking into the heating pin accommodating cavity 5 or the power end 6.
The upper end face of the heating needle accommodating cavity 5 is provided with a circular boss 110 and a second small hole 111 positioned on the surface of the circular boss, and the circular boss 110 is internally provided with a heating needle sealing ring 102 with a central hole and a replaceable oil suction pad 112 with a central hole positioned below the heating needle sealing ring 102; the bottom end face of the tobacco tar soft capsule cartridge 4 is provided with a circular groove 101 and a first small hole 100 positioned on the surface of the circular groove 101, and the circular groove 101 is clamped with the circular boss 110. When the electronic cigarette is not used, the second small hole 111 can be sealed by a plug so as to prevent dust from falling into the heating needle accommodating cavity 5 and polluting the heating needle 5.1. When the heating needle accommodating cavity 5 is combined with the tobacco tar soft capsule cartridge 4, the heating needle sealing ring 102 enters the circular groove 101 in the tobacco tar soft capsule cartridge 4 to seal the heating needle 5.1, so that the tobacco tar is prevented from leaking into the heating needle accommodating cavity. The first small hole, the second small hole and the hole diameters of the heating needle sealing ring and the opening hole in the center of the replaceable oil absorption pad can ensure that all heating sections of the heating needle can extend out of the heating needle accommodating cavity. Preferably, a replaceable oil suction pad 112 with the same outer diameter as that of the sealing ring is arranged below the heating needle sealing ring 102, and is used for absorbing the smoke oil adhered to the heating needle when the heating needle is retracted into the heating needle accommodating cavity, so as to prevent the smoke oil on the heating needle from leaking into the heating needle accommodating cavity.
