Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings so that the advantages and features of the present invention will be readily understood by those skilled in the art, and the scope of the present invention will be clearly and clearly defined.
A preferred embodiment of an electronic cigarette with temperature protection function as shown in fig. 1 to 3; the electronic cigarette comprises a cigarette rod 1 and a cigarette cartridge 2, wherein the cigarette rod 1 is connected with the cigarette cartridge 2 in a detachable mode (such as a thread mode); a battery 11 and a control circuit board 12 are arranged in the tobacco rod 1, and the control circuit board 12 is electrically connected with the battery 11 through a connecting wire; the cartridge 2 comprises a cartridge main body 21, a suction nozzle 22, a tobacco tar bin 23 and an atomizer 24, wherein the suction nozzle 22 is connected to the end part of the flue main body 21, and the end part of the suction nozzle 22 is provided with a suction hole; an atomizer 24 and a tobacco tar bin 23 are arranged in the flue main body 21; an axially arranged flue 25 is arranged in the tobacco tar bin 23, and the flue 2 extends to the top of the suction nozzle 22; the tobacco tar bin 23 stores tobacco tar; the atomizer 24 is arranged at the lower part of the tobacco tar bin 23; the heating element 241 is arranged on the atomizer 24; the heating element 241 is electrically connected to the cartridge electrode 26; the smoke cartridge electrode 26 is connected with the temperature protector 3, and the temperature protector 3 is connected with the smoke rod electrode 13; the tobacco rod electrode 13 is electrically connected with the control circuit board 12 through a connecting lead.
In this embodiment, the atomizer 24 is a ceramic member, and the ceramic member is provided with micropores for allowing smoke to enter; the heating member 241 is a heating wire; the heater wire is coiled around the atomizer 24.
The temperature protector 3 includes a temperature protector upper electrode 31, a positive temperature coefficient thermistor 32, a temperature protector lower electrode 33, and a lower cover plate 34, which are arranged in this order from top to bottom.
When the electronic cigarette normally works, the battery 11, the atomizer 24, the temperature protector 3 and the control circuit are connected to form a loop; after normal power on, the heating element 241 generates high temperature; when sufficient soot contacts the heating element 241, the heating element 241 atomizes the soot entering the atomizer 24 to form a mist, which is drawn out of the atomizer and then into the flue 25, and is sucked out of the suction nozzle by the user; certain heat is taken away by the smoke, and the surface temperature of the heating element is stable. During normal operation, the surface heat of the heating element 241 is conducted to the temperature protector 3 through the smoke cartridge electrode 26, the temperature of the smoke cartridge electrode does not reach the response lower limit of the temperature protector, the resistance value is normally 0.1-0.3 Ω, and the current in the operating circuit is kept normal, as shown in fig. 4 a.
When the tobacco tar is insufficient (the electronic cigarette is dry-burned), the heat generated by the heating element 241 cannot be taken away in time, so that the temperature of the heating element is continuously increased, the temperature of the joint of the smoke cartridge electrode 26 and the temperature protector 3 exceeds the normal working temperature, and finally exceeds the response lower limit of the temperature protector 3, the resistance value of the temperature protector 3 is increased, and the current in the working circuit starts to be reduced, as shown in a graph (4 b); after the continuous working for a period of time, the temperature exceeds the response upper limit of the temperature protector 3, the resistance value is rapidly increased, and the current of the working circuit is rapidly reduced and approaches to zero, as shown in a graph (4 c); the heating member 241 stops heating, and the temperature protector 3 realizes an over-temperature protection function. When the resistance value of the temperature protector is recovered to be normal, the electronic cigarette can work normally.
The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structures or equivalent processes performed by the present invention or directly or indirectly applied to other related technical fields are included in the scope of the present invention.
