DETAILED DESCRIPTION

[0020] Hereinafter, the invention is further described in conjunction with Figures and examples:

[0021] With reference to FIGS. 1 to 3, a rotary switch electronic cigarette includes a cylindrical electronic cigarette body, wherein the electronic cigarette body from top to bottom is divided into retractable smoking nozzle portion 1, electric heating portion 2, and rotary switch controlling portion 3. Retractable smoking nozzle portion 1 covers and snaps on electric heating portion 2, and snaps on an upper end of rotary switch controlling portion 3. Electric heating portion 2 is connected to an upper end of rotary switch controlling portion 3 in a screw thread manner.

[0022] Retractable smoking nozzle portion 1 includes a vertically retractable smoking nozzle 11, lid decorative tube 12 and glass tube 13. Smoking nozzle 11 is clamped at the inlet of the upper end of the lid decorative tube 12. Glass tube 13 engages within the lid decorative tube 12. The lower end of lid decorative tube 12 engages electric heating portion 2, and snaps on the upper end of rotary switch controlling portion 3. Lid decorative tube 12 has hollow leaf-shape observation window 121 on the surface of the periphery.

[0023] Electric heating portion 2 includes heating element 21, ceramic base cup 22, replacement core threaded tube base 23, and ceramic protective sleeve 24. Heating element 21 is fixed to the bottom of the heating cavity of ceramic base cup 22. Ceramic base cup 22 snaps inside ceramic protective sleeve 24. Ceramic protective sleeve 24 snaps on the upper end of replacement core threaded tube base. The upper end of ceramic protective cover 24 is also provided with air permeable and leaking proof lid 25. The lower end of replacement core threaded tube base 23 is a threaded tube. Replacement core threaded tube base 23 is fastened inside the upper end of rotary switch controlling portion 3 through the threaded tube at its lower end upper electrode contact core pole 26 is clamped inside the threaded tube. Upper electrode contact core pole 26 is connected to heating element 21 by a lead.

[0024] Rotary switch controlling portion 3 includes a rotary switch assembly 4, battery sleeve 31, rechargeable battery 32, PCBA control panel 33, and battery base 34. Rotary switch assembly 4 is mounted above battery sleeve 31. Rechargeable battery 32 is fixed to the middle of battery sleeve 31. Battery base 34 covers and engages the bottom of battery sleeve 3. The upper portion of battery base 34 is provided with circular translucent region 341. PCBA control panel 33 is provided with a ween indicator light, and is fixed on battery base 34. PCBA control board 33 is connected to rotary switch assembly 4 and rechargeable battery 32 via the lead. The bottom of battery base 34 is also provided with the charging port. The upper end of rotary switch assembly 4 is connected to the lower end of lid decorative tube 12 in a snap-fit manner.

[0025] Rotary switch assembly 4 includes lid rotating snap ring 41, rotating base 42, battery rotating base 43, rotating; damp base 44, and rotary switch 45, lid rotating snap ring 41 snaps on the upper end of rotating base 42. Rotating base 42 is clamped on battery rotating base 43. Battery rotating base 43 is fixed on the upper portion of battery sleeve 31. The upper end of the battery rotating base 42 is connected to the threaded tube of replacement core threaded tube base 23 through the inner thread. The central portion of rotating base 42 is also clamped with lower electrode contact core pole 46.

[0026] PCBA control panel 33 is provided with a time-out protection circuit, a low-voltage protection circuit, a short circuit protection, and an overload protection circuit.

[0027] Detailed implementation:

[0028] Adding tobacco shred: when it is in use, from the controlling portion of the rotary switch, the retractable smoking nozzle portion is pulled out, while the smoking nozzle is also pulled out. Meanwhile, the tobacco shred is put into the heating cavity of the ceramic base cup. After the tobacco shred is put in, the retractable smoking nozzle portion is clamped on the upper end of the controlling portion of the rotary switch again.

[0029] Turning on the switch: the lid decorative tube is turned 90 degrees clockwise. With the rotation of the lid decorative tube, the rotary switch of the rotary switch assembly is driven to rotate to enable the operation of the PCBA control panel. The heating element starts working to generate heat. Now, through the translucent region of the upper portion of the base battery, the green indicator light can be observed as shining. The smoke can also be seen through the window of the lid decorative tube, showing that the electronic cigarette is in a working status which can be smoked.

[0030] Timeout protection: after the PCBA control panel has continuously worked for 30 seconds, the timeout protection circuit controls the PCBA control panel to stop the output. The green indicator light flashes five times to indicate this.

[0031] Short circuit protection and overload protection: when the PCBA control panel detects that the load is short-circuited or less than 0.5Ω, through short circuit protection circuit or overload protection circuit controls the PCBA control panel to stop the output. The green indicator light flashes three times to indicate this.

[0032] Low voltage protection: when the PCBA control panel detects that the rechargeable battery voltage is lower than 3.4V using the low voltage detecting circuit, it controls the PCBA control panel to stop the output. Meanwhile, the green indicator light flashes eight times to indicate this.

[0033] Turning off the switch: the lid decorative tube is turned 90 degrees counter-clockwise by rotating the lid decorative tube, and the rotary switch of the rotary switch assembly is driven to rotate to disable the operation of the PCBA control panel. The heating element stops generating heat. The green light goes out.

[0034] In summary, after reading the present invention documents, according to the technical solution and the technical idea of the present invention, a variety of other alternative solutions made by one of ordinary skill in the art without creative efforts, are within the scope of the present invention.
