`Technical Field
`
`[0001]
`
`The present utility model relates to a battery-powered heating apparatus.
`
`Background of the Invention
`All electronic atomizers on the market are powered by lithium batteries or other power supplies,
`[0002]
`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 tum on or tum 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
`sensing apparatus, one end of the charging mode detection circuit and one end of the battery charging and

`charging mode detection circuit 23, a battery charging and protection circuit 24, and a light-emitting diode
`drive circuit 25 are disposed in the processing chip 2, an output pin of the heating drive circuit 22 is
`connected to the heating apparatus 3, an output pin of the light-emitting diode drive circuit 25 is connected
`to a light-emitting diode D 1, an input pin of the airflow sensing switch circuit 21 is connected to the sensing
`apparatus 4, one end of the charging mode detection circuit 23 and one end of the battery charging and
`protection circuit 24 are connected to the battery 5, and the other end is connected to a power input end.
`An opening to be used by the heating apparatus is disposed on the housing.
`[0012]
`As shown in Fig. 1, an electronic serial interface 6 is disposed inside the housing 1, an opening
`to be used by the electronic serial interface is disposed inside the housing 1, and the electronic serial
`interface 6 is electrically connected to the processing chip 2. In this embodiment, the electronic serial
`interface 6 is a USB interface.
`[0013]
`As shown in Fig. 2, a pin 1 of the processing chip 2 is set to an input pin of the airflow sensing
`switch circuit, a pin 2 is set to a grounding pin, a pin 3 is set to an output pin of the light-emitting diode
`drive circuit, a pin 4 is set to an output pin of the heating drive circuit, an input pin of the charging mode
`detection circuit, and an input pin of the battery charging and protection circuit, and a pin 5 is set to a power
`input pin.
`[0014]
`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 function 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 Cl, the capacitance value of the
`capacitive airflow sensor Cl changes, thereby triggering the airflow sensing switch circuit 21.
`[0017]
`As shown in Fig. 3, the processing chip is Ul, a battery group is BTl, the sensing apparatus is
`Cl, the heating apparatus is Ll, and the light-emitting transistor is D 1. One end of the capacitor C2 is
`connected to a pin 5 (BAT) of the processing chip Ul, 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 C 1. Then, the heating drive circuit 22
`outputs a voltage to the heating apparatus Ll through PWM. High temperature and heat generated by the
`heating apparatus Ll 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
`D 1, to indicate that the heating apparatus Ll is heating. When the user stops smoking, the processing chip
`2 immediately stops driving the heating apparatus Ll and the light-emitting diode D 1.
`[0018]
`If the user keeps smoking for more than five seconds, the processing chip 2 stops outputting the
`voltage to the heating apparatus Ll and flashes the light-emitting diode D 1 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
`Ll to heat up and flashes the light-emitting diode D 1 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 function of
`the lithium battery 5, so that the lithium battery 5 can be fully 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 Dl. One end of the capacitor C2 is connected to a pin 5 (BAT) of
`the processing chip Ul, 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 D 1 to emit light to indicate that the line is in a charging state. When fully
`charged, the processing chip Ul turns off the light-emitting diode Dl to indicate full charging.
`[0023]
`During charging, when the battery voltage is above 2.9 V, the processing chip Ul charges at full
`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(cid:173)
`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 D 1 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 function, 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.
