     BACKGROUND 
     An electronic cigarette, also known as a virtual cigarette, is used for replacing a normal cigarette. The electronic cigarette has a similar taste as a cigarette. However, with increasing of an output power of a cell assembly of the electronic cigarette and decreasing of a resistance of a heating member of a atomizing device for the electronic cigarette, a temperature of the heating member can become too high.

     First Embodiment 
       FIG. 1  illustrates an electronic cigarette  110 . The electronic cigarette  110  can include a suction nozzle  11 , a liquid reservoir  12   a , 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  12   a , 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  12   a  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. 
     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 . The first liquid guiding member  131  has two ends. A first end  1313  of the first liquid guiding member  131  can be in fluid communication with the liquid reservoir  12   a , and a second end  1311  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  12   a  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  12   a  directly, for example, the second liquid guiding member  132  can include a liquid guiding bulge or pouch (not shown) that extends into and is in fluid communication with the liquid reservoir  12   a . The smoke liquid stored in the liquid reservoir  12   a  can thus be carried to other portions of the second liquid guiding member  132  through the liquid guiding bulge or pouch, thus the first liquid guiding member  131  can be omitted. The heating member  133  can be sleeved on, twined around, adhered to or clinged to the second liquid guiding member  132 . In an alternative embodiment, the second liquid guiding member  132  can be sleeved on, twined around, adhered to or clinged to the heating member  133 . In an alternative embodiment, the heating member  133  can be sleeved on, twined around, adhered to or clinged 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 sleeved on, twined around, adhered to or clinged 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, for example, the heating member  133  can be a porous heating member made of ceramic, 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 , the temperature control switch  139 , and other components, so each component can be received and fastened in the atomizing device  13 . 
     The temperature control switch  139  has the following properties: when a temperature t s  of the temperature control switch  139  is less than an operating temperature T M , the temperature control switch  139  is switched on; when the temperature t s  of the temperature control switch  139  is greater than the operating temperature T M , the temperature control switch  139  is switched off. The operating temperature T M  of the temperature control switch  139  can be slightly lower than an upper operating temperature T H  of the heating member  133  since the temperature t s  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 (not shown), a liquid expansion type temperature control switch (not shown), a gas adsorption type temperature control switch (not shown), and a metal expansion type temperature control switch (not shown). The metal expansion type temperature control switch can include a bimetallic strip switch (not shown) and a memory alloy switch (not shown). The electronic temperature control switch can include a resistance type temperature control switch (not shown) and a thermocouple type temperature control switch (not shown). The temperature relay can include a thermal reed relay (not shown). 
     A temperature control process of the electronic cigarette  110  is as follows. When the temperature t s  of the temperature control switch  139  is less than the operating temperature T M , 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 t s  of the temperature control switch  139  also starts to rise. When the temperature t s  of the temperature control switch  139  is greater than the operating temperature T M , 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 t s  of the temperature control switch  139  drop naturally until the temperature t s  of the temperature control switch  139  is less than the operating temperature T M . When t s  is lower than T M , 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. 
     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 . 
     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 
       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 directly and electrically coupled to each other in series, 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, wherein each characteristics may signify a plurality of properties: the first is that the temperature control switch  139  can be switched on when the temperature t s  of the temperature control switch  139  is less than the operating temperature T M , 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 t s  of the temperature control switch  139  is less than the operating temperature T M , and can be switched on when greater. 
       FIG. 3  illustrates that the control device  14  can include a detecting circuit  141 , a processor  142 , and a switch circuit  143 . 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 . With the increase of the temperature t of the heating member  133 , the temperature t s  of the temperature control switch  139  is also increased. “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. For example, if Action A is to switch “on” a component, Action B is to switch “off” the component. When the temperature t s  of the temperature control switch  139  is less than the operating temperature T M , the temperature control switch  139  can execute action A; when the temperature t s  of the temperature control switch  139  is greater than the operating temperature T M , the temperature control switch  139  can execute action B. The processor  142  can switch on or switch off the switch circuit  143  according to the action of the temperature control switch  139 . The switch circuit  143  electrically coupled to the heating member  133  can be configured to switch on and allow power to the heating member  133  from the power supply device  15 . The switch circuit  143  is also configured to cut off the power to the heating member  133  from the power supply device  15 . 
     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 switch on the switch circuit  143 , 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 t s  of the temperature control switch  139  also starts to rise. When the temperature control switch  139  executes action B, the processor  142  can switch off the switch circuit  143 , 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 t s  of the temperature control switch  139  drops naturally until the temperature t s  of the temperature control switch  139  is less than the operating temperature T M . When t s  is lower than T M , the temperature control switch  139  can execute action A again. The processor  142  can switch on the switch circuit  143  between the power supply device  15  and the heating member  133  again. In this arrangement, the heating member  133  starts to work again. 
     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 . 
     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 . 
     In the second embodiment, the heating member  133  and the temperature control switch  139  is not directly and electrically coupled to each other in series, but each one is coupled independently to a control device  14 . Advantages of the electronic cigarette  120  can be described as follows. 
     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 t s  of the temperature control switch  139  is less than the operating temperature T M , and switched off when greater; or the temperature control switch  139  is switched off when the temperature t s  of the temperature control switch  139  is less than the operating temperature T M , and switched on when greater. 
     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 the cool down from cooling too rapidly when the temperature t of the heating member was too high to begin with and in turn affects the user&#39;s enjoyment.

Either an insulating bushing (not shown) is sleeved on the temperature sensor  134  or an insulation coating (not shown) is coated on the temperature sensor  134 , to prevent direct contact between the temperature sensor  134  and the heating member  133 . In the illustrated embodiment, the temperature sensor  134  can be a PTC thermistor. 
       FIG. 6  illustrates a control device  14  that includes a detecting circuit  141 , a processor  142 , and a switch circuit  143 . The detecting circuit  141  electrically coupled to the temperature sensor  134  can monitor the resistance R of the temperature sensor  134  in real time, and feedback the resistance R of the temperature sensor  134  to the processor  142 . The processor  142  can pre-store the relational data between the resistance value R of the temperature sensor  134  and the temperature T of the temperature sensor  134 , an operational formula of the heating member&#39;s temperature t, an upper operating temperature T H  of the heating member  133 , and a lower operating temperature T L  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 sensor  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 T H  and the lower operating temperature T L  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.
