`Technical Field
`
`[0001]
`
`The present utility model relates to a battery-powered heating apparatus.
`
`Background of the Invention
`
`[0002]
`
`All electronic atomizers on the market are powered by lithium batteries or other power supplies,
`
`and liquid is atomized by using heating wires and is then inhaled by a user. In medical application,
`
`medicinal liquid is atomized. In the application of electronic cigarettes, a simulated traditional tobacco
`
`effect or liquid of another flavor is atomized. All current electronic cigarettes sense a smoking action of the
`
`user by using various switch apparatuses, such as a mechanical switch or a Hall-effect switch, to determine
`
`to turn on or turn off a heating apparatus. All these switch apparatuses have a mechanical part or a magnetic
`
`induction part, and as a result, a product has a short life span and is prone to accidental triggering or lacks
`
`sensitivity.

`
`connected to the battery, the heating apparatus, and the sensing apparatus. An airflow sensing switch circuit,
`
`a heating drive circuit, a charging mode detection circuit, a battery charging and protection circuit, and a
`
`light-emitting diode drive circuit are disposed in the processing chip. An output pin of the heating drive
`
`circuit is connected to the heating apparatus, an output pin of the light-emitting diode drive circuit is
`
`connected to a light-emitting diode, an input pin of the airflow sensing switch circuit is connected to the
`

`
`A battery compartment is disposed inside the housing 1, and the battery is installed inside the
`
`battery compartment. A lithium battery is used as the battery in this embodiment.
`
`[0015]
`
`The heating drive circuit 22 is configured to drive the heating apparatus 3, and the heating drive
`
`circuit 22 outputs a voltage to the heating apparatus 3 through pulse width modulation. The heating
`
`apparatus 3 lights a cigarette and atomizes liquid by generating heat. The heating apparatus 3 may be a
`
`heating wire, a heating resistor, or another material that generates heat by using electric energy. In this
`
`embodiment, the heating apparatus 3 is a heating wire.
`
`[0016]
`
`The sensing apparatus 4 is a capacitive airflow sensor. The airflow sensing switch circuit 21 is
`
`configured to sense smoking actions of a user, and the circuit provides an airflow sensing fill’lCthl’l by
`
`detecting a capacitance value of an external capacitive airflow sensor C 1. When the user smokes, an airflow
`
`is generated. When the airflow flows through the capacitive airflow sensor C1, the capacitance value of the
`
`capacitive airflow sensor C1 changes, thereby triggering the airflow sensing switch circuit 21.
`
`[0017]
`
`As shown in Fig. 3, the processing chip is U1, a battery group is BT1, the sensing apparatus is
`
`C1, the heating apparatus is L1, and the light-emitting transistor is D1. One end of the capacitor C2 is
`
`connected to a pin 5 (BAT) of the processing chip U1, and the other end of the capacitor C2 is grounded.
`
`When the user smokes, an airflow is generated, and the airflow triggers the airflow sensing switch circuit
`
`21 after passing through the capacitive airflow sensing apparatus C1. Then, the heating drive circuit 22
`
`outputs a voltage to the heating apparatus L1 through PWM. High temperature and heat generated by the
`
`heating apparatus L1 are enough to atomize liquid that simulates cigarettes for inhalation by the user.
`
`During heating, the light-emitting diode drive circuit 25 also outputs a current to the light-emitting diode
`
`D1, to indicate that the heating apparatus L1 is heating. When the user stops smoking, the processing chip
`
`2 immediately stops driving the heating apparatus L1 and the light-emitting diode D1.
`
`[0018]
`
`If the user keeps smoking for more than five seconds, the processing chip 2 stops outputting the
`
`voltage to the heating apparatus L1 and flashes the light-emitting diode D1 several times to indicate that
`
`the heating time is too long.
`
`[0019] When a voltage of the lithium battery is less than 3.2 V and after the user smokes to trigger the
`
`airflow sensing switch circuit 21, the processing chip 2 does not output the voltage to the heating apparatus
`
`L1 to heat up and flashes the light-emitting diode D1 several times to indicate that the voltage of the battery
`
`is too low. This can protect the battery 5 from excessively discharging.
`
`[0020]
`
`The charging mode detection circuit 23 may detect whether the present utility model is in a battery
`
`charging mode or a normal heating mode, so that the battery can be normally charged or can normally atomize
`
`liquid. When a voltage of a fourth pin (OUT) of the processing chip 2 is higher than a voltage of the fifth pin

`
`(BAT), the processing chip 2 is in charging mode and is powered off from a USB by using the fourth pin
`
`(OUT) to be used for battery charging. When the voltage of the fifth pin (BAT) is higher than or equal to the
`
`voltage of the fourth pin (OUT), the processing chip 2 is in a normal heating state and can drive the heating
`
`wire to heat up according to instructions of the airflow sensing switch circuit 21.
`
`[0021]
`
`The battery charging and protection circuit 24 provides a charging and protection fill’lCthl’l of
`
`the lithium battery 5, so that the lithium battery 5 can be fiilly charged by using a constant current and a
`
`limited voltage. In addition, the circuit 24 can be connected to another electronic product by the USB
`
`interface 6 and directly charges by using a USB power supply. In a normal working state, the circuit 24 can
`
`detect a voltage of the lithium battery 5 and protect the battery 5 from excessively discharging. The lithium
`
`battery may be of different capacities, different shapes, and different packaging. In this way, the lithium
`
`battery may be directly used for power supply, and no lithium battery protection chip or charging chip
`needs to be added.
`
`[0022]
`
`As shown in Fig. 4, the processing chip is Ul, a battery group is BTl, the sensing apparatus is
`
`Cl, and the light-emitting transistor is D1. One end of the capacitor C2 is connected to a pin 5 (BAT) of
`
`the processing chip U1, and the other end of the capacitor C2 is grounded. When the output pin 4 (OUT)
`
`of the processing chip Ul is connected to a charging power supply (a 5 V power supply or a USB power
`
`supply in the figure), the entire circuit enters a charging state. The processing chip Ul inputs a current (a
`
`constant current of 100 mA) to the lithium battery BTl by using a constant current and a limited voltage
`
`until the battery is fully charged (maximum voltage is 4.2 V). During charging, the processing chip Ul
`
`drives the light-emitting diode D1 to emit light to indicate that the line is in a charging state. When fiilly
`
`charged, the processing chip Ul turns off the light-emitting diode D1 to indicate fiill charging.
`
`[0023]
`
`During charging, when the battery voltage is above 2.9 V, the processing chip Ul charges at filll
`
`speed (100 mA) until the battery is fully charged. If the battery voltage is less than 2.9 V, the processing
`
`chip Ul charges at one tenth of the speed. This can protect the battery and prevent charging with a short-
`circuit.
`
`[0024]
`
`After receiving on/off instructions from the airflow sensing switch circuit, the light-emitting
`
`diode drive circuit 25 drives the light-emitting transistor D1 to display a working state or simulate the light
`
`of a real cigarette.
`
`[0025]
`
`The present utility model is simple and durable and can normally be lit 2,000 times. The present
`
`utility model also has an airflow sensing switch fill’lCthl’l, is also equipped with battery charging and battery
`
`protection functions and can directly take power from the USB interface of other electronic products for
`
`charging purposes.
