Detailed Description
The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and fig. 2, the blowing cylinder capable of being started and stopped by touch sensing includes a central processing unit, and a touch sensing circuit, a key switch circuit, a temperature detection circuit, a motor driving circuit and a heating driving circuit respectively connected to the central processing unit; the motor driving circuit is connected with the motor, and the heating driving circuit is connected with the heater;
the touch sensing circuit is internally provided with a touch sensor M5, the touch sensor M5 is arranged on the handle of the air blowing cylinder and used for sensing a touch signal sent to the central processing unit by the touch sensing circuit when the handle of the air blowing cylinder is sensed to be touched; the central processing unit starts the motor driving circuit and the heating driving circuit when receiving the touch signal, and stops the motor driving circuit and the heating driving circuit when not receiving the touch signal.
The key switch circuit is used for providing working state signals, and the central processing unit controls the working states of the motor driving circuit and the heating driving circuit according to the working state signals provided by the key switch circuit.
Specifically, in the present embodiment, the key switch circuit includes a power switch, a wind speed adjusting switch, and a hot/cold switch. The power switch is used for controlling the power supply states of the motor driving circuit and the heating driving circuit; the wind speed adjusting switch is used for controlling the output power of the motor through the motor driving circuit; the cold and hot switch is used for controlling the output power of the heater through the heating driving circuit.
The temperature detection circuit is used for detecting the temperature of the air blown out by the air blowing cylinder. When the temperature of the air blown by the air blowing cylinder is too high, the user is prompted, and the motor driving circuit and the heating driving circuit can be closed through the central processing unit if necessary.
As shown in fig. 2, in the embodiment of the present invention, the touch sensing circuit includes a touch chip U2, a first pin of the touch chip U2 is connected to a touch sensing control switch SW4 through a first resistor R15, and is connected to the central processing unit through a touch sensing control switch SW 4; meanwhile, the first pin is also connected to the operating power supply VDD5 through a second resistor R16.
The eighth pin of the touch chip U2 is connected to the touch sensor M5 through the touch sensitivity adjustment resistor R6.
Furthermore, a second pin of the touch chip is connected to the ground through a reference capacitor, a third pin is connected to the working power supply through a third resistor, the third pin is also connected to the ground through the first capacitor, and a fourth pin is connected to the ground.
In the embodiment of the present invention, the model of the adopted touch chip is CM8T 211B.
When the touch sensing circuit works, the touch sensor M5 is used for continuously detecting whether the handle of the air blowing tube is touched, wherein the sensitivity of touch sensing can be adjusted through the touch sensitivity adjusting resistor R6. A first pin of the touch chip U2 is an output end of a touch signal, and when the touch sensor M5 does not sense a touch, the level of the first pin is pulled high by the second resistor R16; when the touch sensor M5 senses a touch, the level of the first pin is pulled down by the touch chip U2, and is sequentially transmitted to the first resistor R15 and the touch sensing control switch SW 4; after the touch sensing control switch SW4 senses the low level, it is determined that the touch sensing is effective, and the touch signal is continuously sent to the central processing unit.
When the central processing unit works, the touch control signal sent by the touch sensing circuit and the power switch signal sent by the power switch in the key switch circuit are continuously detected, and when the touch control signal and the power switch-on signal are detected simultaneously, the motor driving circuit and the heating driving circuit work normally.

In the present embodiment, the time period employed is 2 minutes.
Specifically, as shown in fig. 3, the work flow of the air blowing cylinder provided by the embodiment of the utility model is as follows: in a standby state, the power switch is in a closed state; and after the power switch is turned on, continuously detecting whether a touch signal is generated, if no touch signal exists, continuously maintaining the standby state, and if the touch signal exists, enabling the motor and the heater to work. The wind speed and the cold-hot state of the blowing cylinder can be adjusted through the wind speed adjusting switch and the cold-hot change-over switch.
The method comprises the steps of detecting a touch signal uninterruptedly during the working period of a motor and a heater, and maintaining the operation of the motor and the heater under the condition of continuously detecting the touch signal until a power switch is turned off to enter a standby state. When the touch signal is detected to be lost, the motor and the heater stop working, enter a waiting state and start timing, wherein the timing duration is 2 minutes. If the touch signal is detected again within 2 minutes, the motor and the heater are driven according to the state before the touch signal is lost, so that the motor and the heater start to work again, and the wind speed and the cold and hot states are kept unchanged. If the touch signal is not detected after 2 minutes, the standby state is entered, and the power switch is required to be turned on again to restart.
