The atomizing device 13 is electrically connected to a power supply device 15 . The housing 16 is provided with a smoke outlet 161 at one end close to the mouthpiece 11 . The smoke outlet hole 161 communicates with the mouthpiece 11 . The e-liquid stored in the e-liquid cavity 12 a can be delivered to the atomizing device 13 . After the atomization device 13 is electrically driven by the power supply device 15, the smoke liquid is heated to make it atomized, so that the user can obtain a smoking experience.

The atomizing device 13 includes a first liquid guiding element 131 , a second liquid guiding element 132 , a heating element 133 , a temperature control switch 139 and an atomizer seat 135 . One end of the first liquid guiding element 131 communicates with the smoke liquid cavity 12a, and the other end is connected with the second liquid guiding element 132, so as to transport the smoke liquid in the liquid smoke cavity 12a to the second liquid guiding element 132 through capillary action. Alternatively, the second liquid guide element 132 itself directly communicates with the smoke liquid chamber 12a (for example, the second liquid guide element 132 includes a liquid guide protrusion (not shown) that communicates/extends into the smoke liquid chamber 12a , the liquid is transported to other parts of the second liquid guiding element 132 through the liquid guiding convex part), and the first liquid guiding element 131 is omitted. The heating element 133 is wound or sheathed or closely attached to the second liquid guiding element 132 . Alternatively, the second liquid guiding element 132 is wound or sheathed or closely attached to the heating element 133 . Alternatively, the heating element 133 is wound or sheathed or closely attached to the first liquid-guiding element 131 , and the second liquid-guiding element 132 is omitted. Alternatively, the first liquid guiding element 131 is wound or sheathed or closely attached to the heating element 133 , and the second liquid guiding element 132 is omitted. Alternatively, the heating element 133 serves as both a heating element and a liquid guiding element, and the first liquid guiding element 131 and the second liquid guiding element 132 are omitted. The temperature control switch 139 is disposed close to the heating element 133 , or the heating element 133 is sleeved on the temperature control switch 139 . The temperature control switch 139 is connected in series with the heating element 133 . The heating element 133 and the temperature control switch 139 are electrically connected to the power supply device 15 . The atomizer seat 135 is used to fix at least one of the first liquid guiding element 131, the second liquid guiding element 132, the heating element 133, and the temperature control switch 139, so that each element in the atomizing device 13 The position is fixed.

The temperature control switch 139 has the following properties: when the temperature t _s of the temperature control switch 139 < the action temperature _TM , the temperature control switch 139 is closed; when the temperature t _s of the temperature control switch 139 > the action temperature _TM , the temperature control Switch 139 is open. Considering that the temperature t _s of the temperature control switch 139 is slightly lower than the temperature t of the heating element 133, preferably, the operating temperature _TM of the temperature control switch 139 should be slightly lower than the required working temperature of the heating element 133 upper limit T _H . The temperature control switch 139 can be one, two or any combination of two or more of a mechanical temperature control switch, an electronic temperature control switch and a temperature relay. The mechanical temperature control switch includes 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, and the metal expansion type temperature control switch includes a bimetal switch and a memory alloy switch. The electronic temperature control switch includes a resistance temperature control switch and a thermocouple temperature control switch. The temperature relay includes a thermal reed relay.

In other embodiments, the atomizing device 13 may include two or more heating elements 133 and the same number of temperature control switches 139 . The cooperation relationship between the heating element 133 and the temperature control switch 139 is the same as that in the first embodiment. It can be understood that the number of the heating elements 133 and the number of the temperature control switch 139 may not match, but the number of the temperature control switch 139 is at least one.

In this embodiment, the structure of the atomizing device 13 is simple and easy to realize, and the temperature t of the heating element 133 can be controlled only by the temperature control switch 139 .

Second embodiment:

As shown in FIG. 2 , the present invention provides an electronic cigarette 120 . Compared with the first embodiment, this embodiment is different in that: the heating element 133 and the temperature control switch 139 are not directly connected in series, but are electrically connected to a control device 14 respectively, and the control device 14 and the power supply device 15 electrical connection. Wherein, the property of the temperature control switch 139 can be any one of the following two types: 1. When the temperature t _s of the temperature control switch 139<action temperature _TM , the temperature control switch 139 is closed, and when the temperature control switch 139 When the temperature t _s of the temperature control switch ₁₃₉ is greater than the action temperature TM, the temperature control switch 139 is disconnected; 2. When the temperature t _s of the temperature control switch 139 is less than the action temperature _TM , the temperature control switch 139 is disconnected, and when the temperature of the temperature control switch 139 is When t _s >action temperature _TM , the temperature control switch 139 is closed.

As shown in FIG. 3 , the control device 14 includes a detection circuit 141 , a processor 142 and a switch circuit 143 . As the temperature t of the heating element 133 increases, the temperature t _s of the temperature control switch 139 also increases. When the temperature t _s of the temperature control switch 139 <action temperature _TM , the temperature control switch 139 takes action A; when the temperature t _s of the temperature control switch 139 >action temperature _TM , the temperature control switch 139 takes action B. The detection circuit 141 is electrically connected to the temperature control switch 139 , monitors the action of the temperature control switch 139 in real time, and feeds back to the processor 142 . The processor 142 controls the on/off of the switch circuit 143 according to the action of the temperature control switch 139 . The switch circuit 143 is electrically connected to the heating element 133 for closing/disconnecting the circuit between the heating element 133 and the power supply device 15 . Wherein, Action A may be that the temperature control switch 139 is closed, or it may be that the temperature control switch 139 is turned off; Action B is opposite to Action A.

The temperature control process of the electronic cigarette 120 is as follows: when the temperature control switch 139 performs action A, the processor 142 controls the switch circuit 143 to close, the power supply device 15 supplies electric energy to the heating element 133, and the temperature t of the heating element 133 rises High, the temperature t _s of the temperature control switch 139 also increases; when the temperature control switch 139 takes action B, the processor 142 controls the switch circuit 143 to disconnect, the power supply device 15 stops supplying electric energy to the heating element 133, and the heating element 133 The temperature t of the temperature control switch 139 naturally decreases, and the temperature t _s of the temperature control switch 139 also decreases naturally, until the temperature t _s of the temperature control switch 139 < the action temperature T _M , the temperature control switch 139 takes action A again, and the processor 142 controls the switch again The circuit 143 connects the circuit between the power supply device 15 and the heating element 133, so that the heating element 133 works normally again.

In other embodiments, the switch circuit 143 can be replaced by a regulating circuit. When the temperature control switch 139 takes action A, the regulating circuit can adjust the power supply device 15 to reduce the output voltage/power to the heating element 133; When the power/power does not reach the maximum output voltage/power, the regulating circuit can adjust the power supply device 15 to increase the output voltage/power to the heating element 133; When the voltage/power reaches the maximum output voltage/power, the regulating circuit can regulate the power supply device 15 to maintain the output voltage/power to the heating element 133 .

In other embodiments, the atomizing device 13 may include two or more heating elements 133 and the same number of temperature control switches 139 . The cooperation relationship between the heating element 133 and the temperature control switch 139 is the same as that in the second embodiment. It can be understood that the number of the heating elements 133 and the number of the temperature control switch 139 may not match, but the number of the temperature control switch 139 is at least one.

In this embodiment, the heating element 133 and the temperature control switch 139 are not directly connected in series, but are electrically connected to a control device 14 respectively, which has the following advantages:

(1) The temperature control switch 139 has a wider selection range, and its properties can be any one of the following two types: one, when the temperature t _s of the temperature control switch 139＜action temperature _TM , the temperature control switch 139 is closed, When the temperature t _s of the temperature control switch 139 > the action temperature _TM , the temperature control switch 139 is turned off; 2. When the temperature t _s of the temperature control switch 139 < the action temperature _TM , the temperature control switch 139 is turned off, and when the temperature When the temperature t _s of the temperature control switch 139 > the action temperature _TM , the temperature control switch 139 is closed.

(2) The temperature t of the heating element 133 can be adjusted by connecting/disconnecting the circuit between the heating element 133 and the power supply device 15; Adjusting the temperature t of the heating element 133 according to the output voltage/power of the heating element 133 can prevent the heating element 133 from immediately stopping working when the temperature of the heating element 133 is too high, causing the temperature t to drop too fast, thereby affecting the use of the user.

Third embodiment:

As shown in FIG. 4 and FIG. 5 , the present invention provides an electronic cigarette 130 . Compared with the second embodiment, this embodiment differs in that: the temperature sensitive element 134 replaces the temperature control switch 139 and is electrically connected to the control device 14 .

The second liquid guiding element 132 is placed close to or close to the temperature sensitive element 134, and the heating element 133 is wound or sheathed or closely attached to the second liquid guiding element 132 and the temperature sensitive element 134, or only wound or sheathed Set or close to the second liquid guiding element 132 .

Alternatively, the temperature-sensitive element 134 is arranged close to or close to the first liquid-conducting element 131, and the heating element 133 is wound or sheathed or closely attached to the first liquid-conducting element 131 and the temperature-sensitive element 134, or only The second liquid guiding element 132 is omitted because it is wrapped around or sheathed or tightly attached to the first liquid guiding element 131 . Alternatively, the temperature-sensitive element 134 is close to or close to the first liquid-conducting element 131, and the first liquid-conducting element 131 and the temperature-sensitive element 134 are wound or sheathed or closely attached to the heating element 133, or only the second A liquid guiding element 131 is wound or sheathed or closely attached to the heating element 133 , and the second liquid guiding element 132 is omitted. Alternatively, the heating element 133 is sheathed or coated on the temperature sensitive element 134 , the first liquid guiding element 131 is wound or sheathed on the heating element 133 , and the second liquid guiding element 132 is omitted. Alternatively, the heating element 133 serves as both a heating element and a temperature sensitive element, and the temperature sensitive element 134 is omitted. Alternatively, the heating element 133 serves as a heating element, a liquid guiding element and a temperature sensitive element at the same time, and the first liquid guiding element 131 , the second liquid guiding element 132 and the temperature sensitive element 134 are omitted. The heating element 133 is not directly electrically connected to the temperature sensitive element 134 , but is electrically connected to the control device 14 respectively. Alternatively, the heating element 133 is directly electrically connected to the temperature sensitive element 134 , and then electrically connected to the control device 14 . The atomizer seat 135 is used to fix at least one of the first liquid guiding element 131, the second liquid guiding element 132, the heating element 133, and the temperature sensitive element 134, so that each element in the atomizing device 13 The position is fixed. Wherein, in order to prevent the temperature sensitive element 134 from being in direct contact with the heating element 133 , an insulating sheath or an insulating coating can be provided outside the temperature sensitive element 134 . In this embodiment, the temperature sensitive element 134 is a PTC thermistor.

As shown in FIG. 6 , the control device 14 includes a detection circuit 141 , a processor 142 and a switch circuit 143 . The detection circuit 141 is electrically connected to the temperature sensitive element 134 , monitors the resistance R of the temperature sensitive element 134 in real time, and feeds back the resistance R of the temperature sensitive element 134 to the processor 142 . The corresponding relationship data of the resistance value R of the temperature-sensitive element 134 and the temperature T of the temperature-sensitive element 134, the computing formula of the temperature t of the heating element 133 are pre-stored in the processor 142: t=T+ΔT (ΔT: through experiment The resulting difference between the temperature T of the temperature sensitive element 134 and the temperature t of the heating element 133 ) and the upper limit _TH and the lower limit T _L of the operating temperature of the heating element 133 . The processor 142 first calculates the temperature t of the heating element 133, then compares the temperature t of the heating element 133 with the upper limit _TH and the lower limit _TL of the heating element 133, and finally controls the switch circuit 143 according to the comparison result on/off. The switch circuit 143 is electrically connected to the heating element 133 for closing/disconnecting the circuit between the heating element 133 and the power supply device 15 .

The temperature control process of the electronic cigarette 130 is as follows: the temperature T of the temperature sensitive element 134 increases as the temperature t of the heating element 133 increases. The resistance value R of the temperature sensitive element 134 increases as the temperature T of the temperature sensitive element 134 increases. The detection circuit 141 monitors the resistance value R of the temperature sensitive element 134 in real time, and feeds back the resistance value R of the temperature sensitive element 134 to the processor 142 . The processor 142 first calculates the temperature T of the temperature sensitive element 134 according to the corresponding relationship data between the resistance value R of the temperature sensitive element 134 and the temperature T of the temperature sensitive element 134, and then according to the calculation formula of the temperature t of the heating element 133: t =T+ΔT (ΔT: the difference between the temperature T of the temperature sensitive element 134 obtained through experiments and the temperature t of the heating element 133) calculates the temperature t of the heating element 133, and then the temperature t of the heating element 133 and the heating element The upper limit T _H of the operating temperature of the element 133 is compared with the lower limit T _L of the operating temperature, and finally the on/off of the switch circuit 143 is controlled according to the comparison result.
