[0030] The application proposes a vertical PCB fixing structure 100, please refer to Figure 1 、 Figure 2 And Figure 3 , including: shell 101 and circuit board 107, the inside of shell 101 is hollow, and the inside is provided with a containing cavity, the inner wall of the containing cavity extends first guide column 102 and second guide column 104, first guide column 102 is provided with first guide groove 103 along the length direction, second guide column 104 is provided with second guide groove 105 along the length direction, and first guide groove 103 and second guide groove 105 are oppositely arranged.The two sides of circuit board 107 are inserted into first guide groove 103 and second guide groove 105, so that circuit board 107 is limited and buckled in the shell 101 in the way of clamping.The application reduces the use of screw materials, and the number of mold opening is less, the mold cost is reduced, the buckling action is simple, the work efficiency is high;Compact structure, small internal assembly space.
[0031] In an embodiment, the circuit board 107 is a PCB board. The inner walls of the first guide groove 103 and the second guide groove 105 are respectively provided with stepped limiting grooves, the width of the limiting grooves decreases from inside to outside. The two side edges of the circuit board 107 are provided with grooves, and the circuit board 107 is clamped by embedding the grooves into the limiting grooves.

[0032] Please refer to Figure 1 and Figure 2 The bottom of the shell 101 extends out an elastic buckle 106, which is made of a certain elastic plastic material. When the circuit board 107 is inserted, the elastic buckle 106 can avoid the circuit board 107, and then the elastic buckle 106 is smoothly buckled on the groove of the circuit board 107. The connection between the first guide column 102 and the second guide column 104 is an auxiliary line. The elastic buckle 106 is arranged on one side of the auxiliary line, and the circuit board 107 is provided with a clamping groove 108, and the elastic buckle 106 is buckled with the clamping groove 108.
[0033] Further, the top surface of the elastic buckle 106 is an inclined surface, and the height of the top surface of the elastic buckle 106 gradually decreases towards the side of the auxiliary line. When the circuit board 107 is inserted along the first guide groove 103 and the second guide groove 105, the bottom edge of the circuit board 107 will be supported on the top surface of the elastic buckle 106, and the bottom edge of the circuit board 107 will gradually decrease in height along the inclined surface of the top surface, until the bottom edge of the circuit board 107 decreases to the lowest part of the inclined surface. Continue to push the bottom edge of the circuit board 107 until the elastic buckle 106 is buckled on the groove, thereby completing the action of fixing the circuit board 107 in the shell 101. This design reduces the resistance of the bottom edge of the circuit board 107 to decrease and insert, and reduces the working strength of the workers.
[0034] Further, the number of elastic buckles 106 is two. In an embodiment, the two elastic buckles 106 are respectively arranged on the two sides of the auxiliary line. In another embodiment, the two elastic buckles 106 are respectively arranged on the same side of the auxiliary line.

The shell 101 is provided with a light transmission hole, and the light guide lamp 109 is arranged at the light transmission hole, so that the light emitted by the light guide lamp 109 can be transmitted from the light transmission hole. When the circuit board 107 is powered on, the light guide lamp 109 is turned on, indicating whether the product is in a power-on state or a power-off state.
[0036] Further, the product is usually equipped with a rechargeable battery. The charging interface 110 is welded on the circuit board 107, and the mounting port 111 is arranged on the shell 101, and the plug end of the charging interface 110 is arranged on the mounting port 111. The charging interface 110 is electrically connected with the battery. The external power supply is plugged into the charging interface 110 through the charging line to charge the battery. Further, the charging interface 110 is a USB interface, a Lightning interface or a Type-c interface, and the charging interface 110 is diversified, and the USB interface, the Lightning interface or the Type-c interface are the three most common interfaces, and the universality is strong.
[0037] Please refer to Figure 1 and Figure 2 , the front position of the shell 101 is provided with a key hole 113 and a key shell 115. The key shell 115 is arranged in the key hole 113 and can move horizontally. The key switch 112 is welded on the circuit board 107, and the key switch 112 is used to control the power on / off of the circuit board 107. The top end of the key switch 112 is arranged in the key hole 113 and is supported on the key shell 115. When the user presses the key shell 115, the pressure is conducted to the key switch 112 through the movement of the key shell 115, so that the key switch 112 is triggered, and the circuit board 107 is powered on; the key switch 112 is pressed again, and the circuit board 107 is powered off. The key switch 112 on the PCB can be arranged on the front position of the shell 101, which is beautiful and atmospheric, and is convenient to press.
[0038] Please refer to Figure 4 , the shell 101 is provided with two demolding ports 114. After the shell 101 is made on the mold, demolding is needed, and the staff can start from the demolding port 114 to separate the shell 101 from the mold. In addition, the demolding port 114 can balance the air pressure inside and outside the shell 101, and serve as an air inlet channel of the electronic cigarette 200.
[0039] In addition, please refer to Figure 5 , the application also provides an electronic cigarette 200, which comprises a mouthpiece 201, an atomization assembly 202 and the above-mentioned vertical PCB fixing structure 100. The mouthpiece 201 is used as the suction end of the user. The shell 101 is hollow inside, and the bottom is provided with an air inlet hole. The atomization assembly 202 comprises a transparent cover 203 and an atomizer 204. The transparent cover 203 is hollow inside, and the inside is provided with an oil tank. The atomizer 204 is plugged into the oil tank, the oil tank is used to store tobacco tar, and the atomizer 204 is used to atomize the tobacco tar in the oil tank. The air inlet end of the atomizer 204 communicates with the air inlet hole, and the air outlet end of the atomizer 204 communicates with the mouthpiece 201 to form an air flow channel. The vertical PCB fixing structure 100 is arranged below the atomization assembly 202, the circuit board 107 is electrically connected with the atomization assembly 202, and the circuit board 107 supplies power to the atomization assembly 202.
[0040] In summary, the working principle of the electronic cigarette 200 is that external air enters from the air inlet hole on the shell 101, so that the external air enters the atomizer 204 at high speed and mixes with the atomized liquid droplets, reduces the high concentration of the atomized liquid droplets, and makes the mixture of the atomized liquid droplets and the air suitable for the taste of the user. The human oral cavity contacts the cigarette holder 201, so that a negative pressure is formed in the electronic cigarette 200, so that air enters from the air inlet hole opposite the cigarette holder 201. At the same time, the battery supplies power to the circuit board 107 to drive the atomizer 204 to atomize the tobacco tar. The external air passes through the atomizer 204, the air mixes with the atomized liquid droplets in the atomizer 204, and forms a mixed smoke, and finally the mixed smoke is guided from the cigarette holder 201 to the oral cavity. Among them, the atomized liquid droplets are the mist droplets after the tobacco tar is atomized.
