[0066] The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.

First Embodiment:

[0067] FIG.1 illustrates an electronic cigarette 110. The electronic cigarette 110 can include a suction nozzle 11, a liquid reservoir 12a, an atomizing device 13, a power supply device 15, and a shell 16. An end of the suction nozzle 11 can be coupled to the shell 16. All of the liquid reservoir 12a, the atomizing device 13, and the power supply device 15 can be positioned in the shell 16. The atomizing device 13 can be electrically coupled to the power supply device 15. An end of the shell 16 that is adjacent to the suction nozzle 11 can define a vent hole 161. The vent hole 161 can be in fluid communication with the suction nozzle 11. Smoke liquid received in the liquid reservoir 12a can be carried to the atomizing device 13. After the atomizing device 13 is driven by the power supply device 15, the smoke liquid can be heated and atomized, thus the user can enjoy a smoking experience.

[0068] The atomizing device 13 can include a first liquid guiding member 131, a second liquid guiding member 132, a heating member 133, a temperature control switch 139, and an atomizer seat 135. An end of the first liquid guiding member 131 can be in fluid communication with the liquid reservoir 12a, and another end of the first liquid guiding member 131 can be coupled to the second liquid guiding member 132. The smoke liquid received in the liquid reservoir 12a can thus be carried to the second liquid guiding member 132 through capillary action as exemplary embodiment shown in FIG.1. In an alternative embodiment, the second liquid guiding member 132 can be in fluid communication with the liquid reservoir 12a directly. For example, the second liquid guiding member 132 can include a liquid guiding bulge (not shown) that is in fluid communication with or extends into the liquid reservoir 12a. The smoke liquid stored in the liquid reservoir 12a can thus be carried to other portions of the second liquid guiding member 132 through the liquid guiding bulge, thus the first liquid guiding member 131 can be omitted. The heating member 133 can be twined around, sleeved on or adhered to the second liquid guiding member 132. In an alternative embodiment, the second liquid guiding member 132 can be twined around, sleeved on or adhered to the heating member 133. In an alternative embodiment, the heating member 133 can be twined around, sleeved on or adhered to the first liquid guiding member 131, and the second liquid guiding member 132 can be omitted. In an alternative embodiment, the first liquid guiding member 131 can be twined around, sleeved on or adhered to the heating member 133, and the second liquid guiding member 132 can be omitted. In an alternative embodiment, the heating member 133 can function as the heating member but also function as the liquid guiding members, then both of the first liquid guiding member 131 and the second liquid guiding member 132 can be omitted. The temperature control switch 139 can be positioned adjacent to the heating member 133, or the heating member 133 can be sleeved on the temperature control switch 139. The temperature control switch 139 can be electrically coupled to the heating member 133 in series. Both of the heating member 133 and the temperature control switch 139 can be electrically coupled to the power supply device 15. The atomizer seat 135 can be configured as a fixing base for at least one of the following components: the first liquid guiding member 131, the second liquid guiding member 132, the heating member 133, and the temperature control switch 139, so each component can be fastened in the atomizing device 13.

[0069] The temperature control switch 139 has the following properties: when a temperature ts of the temperature control switch 139 is less than an operating temperature TM, the temperature control switch 139 is switched on; when the temperature ts of the temperature control switch 139 is greater than the operating temperature TM, the temperature control switch 139 is switched off. The operating temperature TM of the temperature control switch 139 can be slightly lower than an upper operating temperature TH of the heating member 133 since the temperature ts of the temperature control switch 139 is always slightly lower than the temperature t of the heating member 133. The temperature control switch 139 can be selected from at least one of the following components: a mechanical temperature control switch, an electronic temperature control switch, a temperature relay, and a combination thereof. The mechanical temperature control switch 139 can include a steam pressure type temperature control switch, a liquid expansion type temperature control switch, a gas adsorption type temperature control switch, and a metal expansion type temperature control switch. The metal expansion type temperature control switch can include a bimetallic strip switch and a memory alloy switch. The electronic temperature control switch can include a resistance type temperature control switch and a thermocouple type temperature control switch. The temperature relay can include a thermal reed relay.

[0070] A temperature control process of the electronic cigarette 110 is as follows. When the temperature ts of the temperature control switch 139 is less than the operating temperature TM, the temperature control switch 139 allows power from the power supply device 15 to reach the heating member 133. When the heating member 133 starts to heat up, the temperature t of the heating member 133 starts to rise, and the temperature ts of the temperature control switch 139 also starts to rise. When the temperature ts of the temperature control switch 139 is greater than the operating temperature TM, the temperature control switch 139 switches off the connection between the power supply device 15 and the heating member 133, then the heating member 133 stops working. The temperature t of the heating member 133 and the temperature ts of the temperature control switch 139 drop naturally until the temperature ts of the temperature control switch 139 is less than the operating temperature TM. When ts is lower than TM, the temperature control switch 139 again interconnects the power supply device 15 and the heating member 133 to allow the heating member 133 to heat up again.

[0071] In an alternative embodiment, the atomizing device 13 can include two or more heating members 133 and the same number of temperature control switches 139 as the heating members 133. A relationship between the heating member 133 and the temperature control switch 139 can be the same as in the first embodiment. In an alternative embodiment, the number of the heating members 133 is not equal to the number of the temperature control switches 139. The atomizing device 13 can include at least one temperature control switch 139.

[0072] In the first embodiment, the atomizing device 13 can have a simple structure, and the temperature t of the heating member 133 can be controlled by the temperature control switch 139 alone.

Second Embodiment:

[0073] FIG.2 illustrates an electronic cigarette 120. A difference between the electronic cigarette 120 of the second embodiment and the electronic cigarette 110 of the first embodiment is as follows. The heating member 133 and the temperature control switch 139 are not electrically coupled to each other in series directly, but each one is coupled independently to a control device 14. The control device 14 is electrically coupled to the power supply device 15. The temperature control switch 139 can have one of the following characteristics: the first is that the temperature control switch 139 can be switched on when the temperature ts of the temperature control switch 139 is less than the operating temperature TM, and can be switched off when greater; the second is the opposite of the above, namely, the temperature control switch 139 can be switched off when the temperature ts of the temperature control switch 139 is less than the operating temperature TM, and can be switched on when greater.

[0074] FIG.3 illustrates that the control device 14 can include a detecting circuit 141, a processor 142, and a switch circuit 143. With the increase of the temperature t of the heating member 133, the temperature ts of the temperature control switch 139 is also increased. When the temperature ts of the temperature control switch 139 is less than the operating temperature TM, the temperature control switch 139 can execute action A; when the temperature ts of the temperature control switch 139 is greater than the operating temperature TM, the temperature control switch 139 can execute action B. The detecting circuit 141 can be electrically coupled to the temperature control switch 139 and can monitor the action of the temperature control switch 139 in real time, and feedback to the processor 142. The processor 142 can control the switch circuit 143 to switch on or switch off according to the action of the temperature control switch 139. The switch circuit 143 electrically coupled to the heating member 133, and can be configured to switch on or switch off the circuit between the heating member 133 and the power supply device 15. "Action A" as hereinafter used can mean the temperature control switch 139 being switched on or can mean the temperature control switch 139 being switched off. "Action B" as used hereinafter means in one event opposite of action A.

[0075] The temperature control process of the electronic cigarette 120 is as follows. When the temperature control switch 139 executes action A, the processor 142 can control the switch circuit 143 to switch on, and then the power supply device 15 can supply power to the heating member 133, the temperature t of the heating member 133 starts to rise, and the temperature ts of the temperature control switch 139 also starts to rise. When the temperature control switch 139 executes action B, the processor 142 can control the switch circuit 143 to switch off, and then the power supply device 15 can stop supplying power to the heating member 133. The temperature t of the heating member 133 and the temperature ts of the temperature control switch 139 drops naturally until the temperature ts of the temperature control switch 139 is less than the operating temperature TM. When ts is lower than TM, the temperature control switch 139 can execute action A again. The processor 142 can control the switch circuit 143 to switch on the circuit between the power supply device 15 and the heating member 133 again. In this arrangement, the heating member 133 starts to work again.

[0076] In an alternative embodiment, the switch circuit 143 can be replaced by an adjusting circuit. When the temperature control switch 139 executes action B, the adjusting circuit can adjust the power supply device 15 to decrease the output voltage/output power supplied to the heating member 133. When the temperature control switch 139 executes action A and the output voltage/output power of the power supply device 15 supplied to the heating member 133 is not up to a maximum output voltage/output power, the adjusting circuit can adjust the power supply device 15 to increase the output voltage/output power supplied to the heating member 133. When the temperature control switch 139 executes action A and the output voltage/output power of the power supply device 15 supplied to the heating member 133 is up to the maximum output voltage/output power, the adjusting circuit can adjust the power supply device 15 to maintain the output voltage/output power supplied to the heating member 133.

[0077] In an alternative embodiment, the atomizing device 13 can include two or more heating members 133 and the same number of temperature control switches 139 as the heating members 133. The relationship between the heating member 133 and the temperature control switch 139 can be the same as that in the second embodiment. In an alternative embodiment, the number of the heating members 133 is not equal to the number of the temperature control switches 139. The atomizing device 13 can include at least one temperature control switch 139.

[0078] In the second embodiment, the heating member 133 and the temperature control switch 139 is not electrically coupled to each other in series directly, but each one is coupled independently to a control device 14. Advantages of the electronic cigarette 120 can be described as follows.

(1) The choice of the temperature control switch 139 can be wider, so long as the temperature control switch 139 can have one of the following properties: the temperature control switch 139 is switched on when the temperature ts of the temperature control switch 139 is less than the operating temperature TM, and switched off when greater; or the temperature control switch 139 is switched off when the temperature ts of the temperature control switch 139 is less than the operating temperature TM , and switched on when greater.

(2) The control device can connect or disconnect circuit between the heating member 133 and the power supply device 15 to adjust the temperature t of the heating member 133, or the output voltage/output power to the heating member 133 can be supplied variably under a control of the regulating circuit to adjust the temperature t of the heating member 133, thus preventing cooling too rapidly when the temperature t of the heating member was too high and avoiding to affect the user's enjoyment.

The atomizer seat 135 can be configured as the fixing base for at least one component of the following components: the first liquid guiding member 131, the second liquid guiding member 132, the heating member 133, and the temperature sensitive member 134, so each component can be fastened in the atomizing device 13.

The detecting circuit 141 electrically coupled to the temperature sensitive member 134, and can monitor the resistance R of the temperature sensitive member 134 in real time, and feedback the resistance R of the temperature sensitive member 134 to the processor 142. The processor 142 can pre-store the relational data between the resistance value R of the temperature sensitive member 134 and the temperature T of the temperature sensitive member 134, an operational formula of the heating member's temperature t, an upper operating temperature TH of the heating member 133, and a lower operating temperature TL of the heating member 133. The operational formula is described as follows: t=T+ΔT, ΔT means the difference between the temperature T of the temperature sensitive member 134 and the temperature t of the heating member 133 that are achieved from tests. The processor 142 can calculate the temperature t of the heating member 133, and then can compare the temperature t of the heating member 133 with the upper operating temperature TH and the lower operating temperature TL of the heating member 133, and then can control the switch circuit 143 to switch on or switch off according to the result of the comparison. The switch circuit 143 electrically coupled to the heating member 133, and can be configured to switch on or switch off the circuit between the heating member 133 and the power supply device 15.

[0082] The temperature control process of the electronic cigarette 130 is as follows. The temperature T of the temperature sensitive member 134 can rise with the rising temperature t of the heating member 133. The resistance value R of the temperature sensitive member 134 can be increased with the rising temperature T of the temperature sensitive member 134. The detecting circuit 141 can monitor the resistance R of the temperature sensitive member 134 in real time, and feedback the resistance R of the temperature sensitive member 134 to the processor 142. The processor 142 can calculate the temperature T of the temperature sensitive member 134 according to the relational data between the resistance value R of the temperature sensitive member 134 and the temperature T of the temperature sensitive member 134, and then can calculate the temperature t of the heating member 133 according to the following operational formula: t=T+ΔT (ΔT means the difference between the temperature T of the temperature sensitive member 134 and the temperature t of the heating member 133 that are achieved from tests), and then can compare the temperature t of the heating member 133 with the upper operating temperature TH and the lower operating temperature TL of the heating member 133, and then can control the switch circuit 143 to switch on or switch off according to the result of comparison. When the temperature t of the heating member 133 is less than the upper operating temperature TH, the processor 142 can control the switch circuit 143 to be switched on, and then the power supply device 15 can supply power to the heating member 133, the temperature t of the heating member 133 can rise; when the temperature t of the heating member 133 is greater than the upper operating temperature TH, the processor 142 can control the switch circuit 143 to be switched off, and then the power supply device 15 can stop supplying power to the heating member 133, the temperature t of the heating member 133 can drop naturally until the temperature t of the heating member 133 is equal to the lower operating temperature TL. When the temperature t is equal to the lower operating temperature TL, the power supply device 15 can start to supply power to the heating member 133 again.

[0083] In an alternative embodiment, the switch circuit 143 can be replaced by an adjusting circuit. When the temperature t of the heating member 133 is greater than the upper operating temperature TH, the adjusting circuit can adjust the power supply device 15 to decrease the output voltage/output power supplied to the heating member 133. When the temperature t of the heating member 133 is less than the lower operating temperature TL and the output voltage/output power of the power supply device 15 supplied to the heating member 133 is not up to a maximum output voltage/output power, the adjusting circuit can adjust the power supply device 15 to increase the output voltage/output power supplied to the heating member 133. When the temperature t of the heating member 133 is less than the lower operating temperature TL and the output voltage/output power of the power supply device 15 supplied to the heating member 133 is up to the maximum output voltage/output power, the adjusting circuit can adjust the power supply device 15 to maintain the output voltage/output power supplied to the heating member 133.
