When the slide column 6 is pressed downwards, the hidden part of the large key 33 is inserted into the hidden groove 608 of the slide column 6, and the limiting bulge is also inserted into the vertical limiting groove 3302, at the moment, the large key 33 is prevented from moving rightwards due to the limiting bulge, and a user cannot press the large key 33 at the moment, so that the electronic cigarette is prevented from working and burning out the ultrasonic atomization sheet 16 caused by mistakenly touching the large key 33 when the slide column 6 is pressed to replace the cigarette cartridge 21.

c. When smoking, the large key 33 is pressed, and at the moment, the top surface of the hidden part on the large key 33 is propped against the limit bulge of the sliding column 6, so that the sliding column 6 cannot be pressed downwards, and the fact that the cartridge 21 cannot be replaced in the smoking process of the electronic cigarette is ensured.

As shown in fig. 20 to 27, in the first embodiment, the process of replacing the heating assembly 2 is as follows:

a. the top cover 24 is opened: due to the elastic force exerted rightward by the springs five 26, when the slide assembly 38 is pressed downward and the top cover assembly 23 is released, the cover can be slid rightward along the guide groove 2501 of the guide plate 25. The first spring 15 is arranged in the top column 14, the support lug 1401 of the top column 14 is assembled corresponding to the semicircular mounting groove 603 of the sliding column 6 and rotates along the rotating guide groove 604, and the top column 14 cannot be separated when the upper end face of the support lug 1401 of the top column 14 moves upwards to the limit end face 6051 due to the upward force of the first spring 15 on the top column 14.

b. The process of installing the heating component 2 comprises the following steps: since the second spring 11 is disposed on the right end face of the slider 7, the second spring 11 applies a leftward force to the slider 7, so that the slider 7 always has a leftward movement tendency. The four sides of the conductive ring 18 are provided with the buckling grooves 20, and the top of the sliding block 7 is provided with the buckling part 701, so when the conductive ring 18 and the sliding block 7 start to contact, the end part of the sliding block 7 is in an inclined surface shape, so that the heating assembly 2 can be conveniently and continuously pressed downwards for assembly, and the sliding block 7 can be pressed to move rightwards. The heating component 2 is then assembled by pressing downwards, the bottom of the conductive ring 18 and the top column 14 start to contact, so that the pressing hand feeling is better, until the buckling part 701 of the sliding block 7 is buckled into the buckling groove 20 of the conductive ring 18, and the heating component 2 is locked. Since the seal 17 is made of soft silica gel material, the lead wire can directly pierce the seal 17 to the outside in pressing contact with the conductive ring 18. The first spring 15 is arranged under the top column 14, the first spring 15 applies an upward force to the top column 14, and the top surface of the top column 14 applies an upward force to the conducting ring 18, so that the heating component 2 has a trend of upward movement, and the clamping groove 20 of the conducting ring 18 is tightly contacted with the sliding block 7, so that good contact between the positive and negative leads of the heating component 2 can be ensured, namely, the heating component 2 can work normally after being locked.

c. Unlocking the heating assembly 2 state: the sliding column 6 and the sliding block 7 are provided with corresponding vertical limiting steps 602, and the first plane 6011 and the second plane 702 are opposite to each other as the limiting position of the sliding block 7 moving leftwards, so that the sliding block 7 does not rotate in the moving process. A spring IV 13 is penetrated below the ejector rod 10, the ejector rod 10 is riveted and fixed with the key block 12, the rotating tongue 8 is penetrated and limited in the sliding column 6 by the rotating shaft 9, the top of the rotating tongue 8 is embedded into a U-shaped groove of the sliding block 7, and the sliding block 7 slides in a circular accommodating hole 601 of the sliding column 6. When the key block 12 is pressed upwards, the turning tongue 8 rotates clockwise to drive the sliding block 7 to move rightwards, the sliding block 7 is separated from the heating component 2, the first spring 15 is arranged below the top column 14, the first spring 15 always applies an upward force to the top column 14, and the heating component 2 is instantaneously jacked by the top column 14 due to the fact that the sliding block 7 is instantaneously separated from the heating component 2, namely, the heating component 2 can be poured downwards. After the unlocking of the heating component 2 is finished, the second spring 11 has left elasticity on the sliding block 7, so that the sliding block 7 resets to drive the turning tongue 8 to reset; the spring IV 13 has a downward elasticity to the push rod 10, and the key block 12 is reset.

The heating component 2, the cartridge 21 and the suction nozzle 37 can be replaced as a whole, which is more convenient. The same structure as that of the first embodiment is not repeated here, but does not affect the understanding and implementation of the present invention by those skilled in the art.

Example III

As shown in fig. 34 to 36, the third embodiment of the electronic cigarette has a similar structure to the first embodiment, and is different in that a cartridge 21 is further disposed in a groove at the top of the sliding column 6, a suction nozzle 37 is disposed at the top of the housing 1, the heating component 2 includes an ultrasonic atomization sheet 16 and a conductive ring 18 outside the ultrasonic atomization sheet 16, the cartridge 21 is disposed in the suction nozzle 37, a sealing seat 17 is disposed between the cartridge 21 and the suction nozzle 37, the cartridge 21, the sealing seat 17 and the suction nozzle 37 are connected into a whole, and a fastening groove 20 corresponding to the fastening part 701 is formed on the side wall of the suction nozzle 37; one pole of the ultrasonic atomizing sheet 16 is abutted against the elastic electrode 19 and is electrically connected with one pole of the power supply through the elastic electrode 19; the other electrode of the ultrasonic atomization sheet 16 is welded with a lead wire which is in pressing contact with the conducting ring 18, and the sliding block 7 is welded with the lead wire and is electrically connected with the other electrode of the power supply; when the locking part 701 locks the locking groove 20, the suction nozzle 37 abuts against the conductive ring 18. In the locked state, the heating assembly 2 is pressed and conducted by clamping the clamping groove 20 on the cartridge 21 through the clamping part 701 on the sliding block 7. The heating component 2 and the cartridge 21 are two independent components, the outer diameter of the heating component 2 is smaller than that of the cartridge 21, and the heating component and the cartridge 21 are replaced respectively, so that the use cost can be reduced, and the assembly is more convenient and quicker. The same structure as that of the first embodiment in the third embodiment is not repeated here, but does not affect the understanding and implementation of the present invention by those skilled in the art.
