Description

Technical Field

[0001] This invention relates to a vibration-sensing hair dryer start / stop control method. Background Technology

[0002] Existing hair dryers operate continuously after being turned on by the user. If the user forgets to turn off the hair dryer or leaves the room, the hair dryer may become overloaded due to continuous operation, and the hot air may ignite nearby flammable materials, posing a significant safety hazard.

[0003] In response, hair dryers on the market require the user to hold or press a trigger button to operate, such as the switch and hair dryer disclosed in CN202121728102.7. This device has a mechanical press switch and a sensor switch. When the mechanical press switch is not pressed and / or the sensor switch does not detect the handle being held, the main control circuit board can control the hair dryer to stop working. While this technical solution solves the problem of turning off the hair dryer when not held by the user, it still has drawbacks: the user needs to keep their finger pressed on the mechanical press switch continuously, which not only causes finger fatigue but also makes it difficult to change the grip position. Especially when switching hands or when the finger is not aligned with the mechanical press switch, the hair dryer will stop, affecting the user experience.

[0004] Therefore, it is necessary to optimize the logic of the hair dryer's sensor control to make the product more closely match user needs. Summary of the Invention

[0005] This invention proposes a vibration-sensing hair dryer start-stop control method, the purpose of which is to provide a safe control mechanism for hair dryer products under non-hand operation, which is specifically achieved through the following technical means.

[0006] The present invention provides a vibration-sensing hair dryer start / stop control method, which includes the following operations: It is equipped with a start switch and a vibration sensor that are connected to the hair dryer controller; The start switch has two positions: pressed and released, and is used to send an operation signal to the hair dryer controller to start or stop the motor. The vibration sensor is configured to continuously output a vibration sensing signal to the hair dryer controller when the hair dryer is in motion. The hair dryer controller is configured to: When continuously receiving vibration sensing signals, the motor is started or stopped in response to the operation signal issued by the start switch; If the vibration sensor signal connection is interrupted for more than m seconds, the speaker or buzzer will be activated to remind the user, and a shutdown countdown will begin. Force the motor to shut down when the countdown reaches zero; If a continuous vibration signal is received again before the countdown reaches zero, the reminder will stop and the shutdown countdown will exit. The system will then continue to respond to the operation signals issued by the start switch to start or stop the motor.

[0007] In one or more embodiments of the present invention, the hair dryer controller is configured to: After the countdown reaches zero, it enters a self-locking state, which means that the hair dryer controller shuts down the motor and stops responding to the start switch to start the motor. When the hair dryer controller is in the self-locking state, it will release the self-locking state and resume operation response to the start switch after receiving a continuous vibration sensing signal again.

[0008] In one or more embodiments of the present invention, the vibration sensor is a vibration motor or acceleration sensor located on the handle of a hair dryer.

[0009] Compared with the prior art, the advantages of the present invention are reflected in: 1) By using vibration sensors to sense the user's grip on the hair dryer, a shutdown protection mechanism is executed within a certain period of time after the user puts down the hair dryer. This prevents the hair dryer from overloading due to the user forgetting to turn it off, and avoids situations such as hot air igniting nearby flammable materials, thus improving the safety performance of the hair dryer.

[0010] 2) After the countdown stops, a self-locking mechanism is activated. The user needs to hold the card and press the start switch again to release the self-locking state, so as to prevent it from being activated when sliding, falling or picked up by a young child.

[0011] 3) It satisfies the user's perception of the hair dryer's grip status and makes the grip more flexible. There is no need to continuously press the switch. Especially when switching hands or when the finger is not aligned with the mechanical switch, the hair dryer will not stop and affect the user experience. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the internal structure of a vibration-sensing hair dryer.

[0013] Figure 2 This is a flowchart of the start / stop control method for a vibration-sensing hair dryer. Detailed Implementation

[0014] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution: See appendix Figure 1 and 2A method for controlling the start and stop of a vibration-sensing hair dryer, wherein the vibration-sensing hair dryer is provided with a start switch 2 and a vibration sensor 4 connected to the hair dryer controller, and a power switch 1 for connecting to the power supply; the vibration sensor 4 is a vibration motor or acceleration sensor located on the handle of the hair dryer. This method includes the following operations: The start switch 2 has two positions: pressed and released, which are used to send an operation signal to the hair dryer controller to start or stop the motor. The vibration sensor 4 is configured to continuously output a vibration sensing signal to the hair dryer controller when the hair dryer is in a moving state. The hair dryer controller is configured to: While continuously receiving vibration sensing signals, the motor is started or stopped in response to the operation signal issued by the start switch 2; If the vibration sensor signal is interrupted for m seconds (e.g., 30, 50 seconds, etc.), the speaker or buzzer will be activated to remind the user and start a countdown to shutdown. The device also has a prompt audio recorded in the memory on the mainboard of the hair dryer. The audio includes reminders to the user to pay attention to safety, how many seconds after which the hair dryer will be forcibly shut down, or instructions on how to use the hair dryer. Force the motor to shut down when the countdown reaches zero; If a vibration sensor signal is received again before the countdown reaches zero, the reminder will stop and the shutdown countdown will exit. The motor will continue to start or stop in response to the operation signal issued by the start switch 2.

[0015] Furthermore, the hair dryer controller enters a self-locking state after the countdown reaches zero. The self-locking state means that the hair dryer controller shuts down the motor and stops responding to the start switch 2 to start the motor. In the self-locked state, upon receiving a continuous vibration signal again, pressing the start switch 2 will release the hair dryer controller from the self-locked state and restore its operational response to the start switch 2. Alternatively, the self-locked state can also be released by powering off and restarting the device. This power-off and restart operation can be performed via power switch 1 or by unplugging and plugging in the hair dryer's power cord.

[0016] When the user plugs in the hair dryer (power switch 1 is on), the hand holding the hair dryer will shake it, causing the vibration motor to output (i.e., a vibration sensing signal). The hair dryer controller then determines that the hair dryer is being held normally and responds to the operation signal from the start switch 2 to start or stop the motor. If the vibration sensing signal is continuously interrupted, it is possible that the hair dryer has been put down. To avoid false alarms, the hair dryer is only considered not to have been moved after a 30-second interruption of the vibration sensing signal (this time can be set according to actual needs, for example, between 5 and 120 seconds). Subsequently, a reminder and a countdown to shutdown are executed. If the user picks up the hair dryer again during the countdown, the reminder stops, and the hair dryer can be used normally.

[0017] To prevent the vibration-sensitive hair dryer from being activated when it is slid, dropped, or picked up by a young child, the hair dryer controller is equipped with a self-locking mechanism. After the countdown reaches zero, it enters a self-locking state, which shuts off the motor and stops responding to the start switch 2 to start the motor. Only when a continuous vibration sensing signal is received again (for example, after 3 seconds) and the start switch 2 is pressed again will the hair dryer controller release the self-locking state and resume responding to the start switch 2.

[0018] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
