[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0034] The utility model provides an electronic cigarette 10, see Figure 1 The electronic cigarette 10 includes a first shell 11 and a second shell 12 connected to the first shell 11, the first shell 11 and the second shell 12 form a containing space for accommodating a cigarette cartridge unit 20 and a control unit 30; the first shell 11 and the second shell 12 have a front end 110 and a rear end 120 along the longitudinal x direction; the front end 110 is provided with an air outlet 113, and the air outlet 113 is connected to the suction nozzle 13; the rear end 120 is provided with an air inlet 114 (112b and 122a).

[0035] The first shell 11 and the second shell 12 are snap-connected along the x direction, and the second shell 12 is snap-connected to the outside of the first shell 11 to form a whole. By removing the second shell 12, the battery or other component units in the control unit 30 can be replaced or recycled, which is convenient for classification, recycling and reuse.

[0036] For example, see Figure 2 A protrusion 111 is provided on the side of the first shell 11 toward the opening direction, and the protrusion 111 has a first through hole 111a for setting the power on and off buttons. A cofferdam 112 is provided circumferentially along the opening direction of the first shell 11, and the inner side 1121 of the cofferdam 112 close to the opening extends to the inner side of the first shell 11, and the outer side 1122 of the cofferdam 112 close to the opening forms a step 1123 with the outer side of the first shell 11. The second shell 12 is clamped on the cofferdam 112 of the first shell 11, and the outer side of the second shell 12 is flush with the outer side of the first shell 11 to form a complete shell.

[0037] For example, see Figure 2 and Figure 4 The cofferdam 112 has a notch 112a at one end to absorb production errors during production and deformation during assembly or disassembly. Figure 2 As shown, the notch 112a is arranged in the tail end 120 area, and a first half-slot 112b is formed along the notch 112a extending toward the first shell 11. This structure is convenient for eliminating stress concentration generated during the production process and is convenient for positioning processing; the first half-slot 112b matches the second half-slot 122a on the second shell 12 to form an air inlet 114. It can be known that the air inlet 114 can be separately arranged in the tail end 120 area of ​​the first shell 11, and can also be separately arranged in the tail end 120 area of ​​the second shell 12.

[0038] See also Figure 2 and Figure 3 Chamfers 112c are arranged at intervals along the circumference of the cofferdam 112, and the thickness of the chamfers 112c gradually decreases along the opening direction of the first shell 11. A second through hole 112d is opened on the central axis of the chamfer 112c near the step 1123.

[0039] The second housing 12 is snap-fitted to the first housing 11. For details, see Figure 5 The opening direction of the side surface of the second shell 12 corresponds to the raised portion 111 on the first shell 11 to form a groove 121 , and the groove 121 matches the raised portion 111 .

[0040] For example, see Figure 5A circumferentially arranged enclosure 122 is arranged along the opening direction of the second shell 12, the enclosure 122 cooperates with the cofferdam 112, and the enclosure 122 is sleeved on the outside of the cofferdam 112. Specifically, a second half-slot 122a is provided on the enclosure 122 of the second shell 12 corresponding to the first half-slot 112b, and this structure facilitates processing and assembly positioning.

[0041] Furthermore, raised blocks 122b are arranged at intervals on the enclosure 122 of the second shell 12, and the raised blocks 122b match the second through holes 112d, that is, the raised blocks 122b can be inserted into the second through holes 112d. In some embodiments, the raised blocks 122b fit tightly with the second through holes 112d to prevent the first shell 11 and the second shell 12 from being loose or unstable after being connected.

[0042] See also Figure 6 The protruding block 122b is provided with an inclined surface 122b1 on the side surface along the opening direction of the second shell 12. When the first shell 11 and the second shell 12 are clamped, the protruding block 122b slides along the chamfer 112c on the cofferdam 112 and enters the second through hole 112d to achieve a stable clamping. The protruding block 122b is provided with an inclined surface 122b1, which can be easily and quickly inserted into the chamfer 112c on the cofferdam 112 for clamping.

[0043] In some embodiments, the protruding block 122b has a slot 122b2 on one side of the inclined surface 122b1, and the length of the slot 122b2 is smaller than the length of the protruding block 122b. When separating the first shell 11 and the second shell 12, a tool can be used to separate the protruding block 122b from the second through hole 112d through the slot 122b2 to achieve quick disassembly.

[0044] Furthermore, a stop plate 122c is disposed on the enclosure 122 of the second housing 12, and the stop plate 122c includes a stop portion 122c1 and a limit portion 122c2. Figure 6As shown, the stopper portion 122c1 extends along the opening direction of the second shell 12, and there is a gap between the stopper portion 122c1 and the enclosure 122, which is used to insert or pull out the cofferdam 112 and prevent the cofferdam 112 from bending toward the inside of the second shell 12 cavity; the limiting portion 122c2 abuts against the enclosure 122, and the limiting portion 122c2 is close to the inside of the second shell 12 cavity; when the first shell 11 and the second shell 12 are snap-fitted, the protruding block 122b slides along the chamfer 112c on the cofferdam 112 and enters into the second through hole 112d. At this time, the front end of the cofferdam 112 just abuts against the limiting portion 122c2, thereby improving the stability of the snap-fit.

[0045] See also Figure 7 The second shell 12 defines a third through hole 123 for setting a USB interface.

[0046] See also Figure 8 The front end of the cigarette cartridge unit 20 is connected to the suction nozzle 13. The cigarette cartridge unit 20 is accommodated in the first shell 11. The cigarette cartridge unit 20 includes an atomizer and necessary components, including an oil (liquid) storage pipe (warehouse), oil (liquid) storage cotton, a ventilation pipe, etc.

[0047] See also Fig. 9 The control unit 30 includes a PCB board 31, an on / off button 311, a USB interface 312, and a battery 32 disposed on the other side of the PCB board 31. The battery 32 is a rechargeable battery, and the user can charge it through the USB interface.

[0048] The battery 32 provides operating voltage for the PCB board 31 and the atomizer 21 , and the on / off button 311 and the USB interface 312 are electrically connected to the PCB board 31 .

[0049] It should be noted that the USB interface 312 includes a Type-A, Type-B or Type-C standard interface.
