When the electronic cigarette rod 101 is pulled out from the preset position of the heating insulation sleeve, the tact switch 8 bounces and disconnects the power connection of the main control circuit board 2, and all circuits of the main control circuit board 2 stop working.

When the electronic cigarette rod is pulled out from the preset position of the heating insulation sleeve, the light touch switch 8 bounces and disconnects the power supply connection of the main control circuit board 2, and all circuits of the main control circuit board 2 stop working; the temperature sensing element 5 is used for detecting the temperature of the rear end of the electronic cigarette rod 101, and after the electronic cigarette rod 101 is inserted into the heating insulation sleeve, the probe of the temperature sensing element 5 is in direct contact with the end face of the rear end of the electronic cigarette rod.
In this embodiment, the temperature sensing element 5 is a thermistor, and the main control circuit board 2 detects the real-time temperature of the rear end of the electronic cigarette rod 101 by detecting the resistance value of the thermistor and performing conversion operation; the electric heating element 4 is used for heating the electronic cigarette rod 101 inserted into the heating insulation sleeve, in the embodiment, the mesh-shaped resistance wire is used as the electric heating element, a circle of resistance wire is laid along the inner wall of the outer shell sleeve 1, in order to make the inner temperature of the heating insulation sleeve more uniform, the laying position is as close to the electronic cigarette rod battery 102 as possible, and the laying area is as large as possible (if the inner surface of the outer shell sleeve 1 is coated with a layer of insulation material, the mesh-shaped resistance wire is embedded into the whole insulation material as uniformly as possible).

Example 3
In this example, the circuit configuration of the heating jacket according to the present invention is explained based on example 1.
Fig. 3 is a schematic diagram of a circuit structure of a heating thermal insulation cover according to embodiment 2 of the present invention, in which a main control circuit board 2 is externally connected with an electric heating element 4, a temperature sensing element 5, a status indicator light 7 and a buzzer 10, and is connected with a battery 3 through a tact switch 8.
The main control circuit board 2 is internally provided with a main control circuit, a battery power detection circuit, a timing dormancy circuit and a charging output control circuit, wherein the battery power detection circuit is used for monitoring the current power of a battery for heating the heat preservation sleeve, when the battery power is detected to be too low, the main control circuit drives the state indicator lamp 7 to flash in red light, and simultaneously drives the buzzer 10 to give out warning sound. The timed sleep circuit is used for effectively saving the overall power consumption of the heating insulating sleeve as far as possible so as to prolong the working time of the battery 3. When the temperature sensing element 5 monitors that the temperature of the rear end of the electronic cigarette rod 101 is higher than a preset room temperature threshold (for example, 25 ℃), the timing sleep circuit enables the main control circuit board 2 to enter a low power consumption sleep mode, awakens the main control circuit board 2 after a preset period of time (for example, 60 seconds), and re-detects the temperature of the electronic cigarette rod 101, so that the detected temperature is still higher than the preset room temperature threshold, and then enters the timing sleep mode again. In the sleep mode, all the circuits on the main control circuit board 2 except the timing sleep circuit stop working normally and are in a sleep state with extremely low power consumption. Considering that when a user uses the electronic cigarette rod to smoke, the temperature of the electronic cigarette rod heating piece 105 is very high (generally reaching about 300 ℃), and part of the heat is conducted to the rear end of the electronic cigarette rod, so that the temperature of the rear end of the electronic cigarette rod 101 is higher in the whole smoking process, and the design of the timing dormancy circuit can effectively reduce unnecessary power consumption of the battery 3. In addition, considering that after the electronic cigarette rod is inserted into the heating insulation sleeve, the inside of the electronic cigarette rod is a narrow and closed space and the requirement on the heating speed is not high, in order to prolong the service time of the battery 3 after being charged once and avoid the influence of large current output on the service life of the battery 3, the power of the mesh resistance wire selected by the electric heating element 4 is not too large, the resistance value is not too small, and generally about 10 ohm to 100 ohm is selected.
The heating insulation sleeve is also designed to have the function of a charger, a charging output connector 11 is fixedly installed at a proper position of the heating insulation sleeve, after the electronic cigarette rod 101 is inserted into the heating insulation sleeve at a proper rotating position, an electronic cigarette rod charging port 103 at the rear end of the electronic cigarette rod 101 can be just aligned with the charging output connector 11 and mutually inserted, at the moment, if a charging output control circuit on a main control circuit board 2 detects that the voltage of the electronic cigarette rod battery 102 is too low and a battery electric quantity detection circuit detects that the electric quantity of the battery 3 of the heating insulation sleeve is sufficient, the charging output control circuit charges the electronic cigarette rod battery 102 through the charging output connector 11 until the voltage difference between the battery 3 of the heating insulation sleeve and the electronic cigarette rod battery 102 is smaller than a preset voltage difference value, and then the charging is stopped.
The batteries 3 of the heating and heat-insulating sleeve are all rechargeable batteries, the charging input interface 6 is arranged in the heating and heat-insulating sleeve, and the external charger can charge the batteries 3 through the charging input interface 6 and the charging input control circuit.
