Abstract

A personal care device capable of being automatically started and shut down intelligently comprises a holding part and an action part, wherein the holding part comprises a metal sheet, a capacitance value generated when the metal sheet approaches to a human hand changes according to whether the holding part is held or not, a control device electrically connected with the metal sheet and used for controlling the processing action of the action part, the personal care device comprises a holding detection part and a control signal output part, the holding detection part detects whether the holding part is held or not according to the change of the capacitance value and outputs a first trigger signal, the control signal output part outputs a control signal according to whether a second trigger signal allowing the action part to act is received or not during the first trigger signal obtaining period, and the control device is used for vibrating a switch and generating the second trigger signal during vibration, wherein the second trigger signal is valid only when the first trigger signal exists. The hand is used to approach the holding part so as to change the capacitance value of the metal sheet to be used as a first trigger signal, so that the personal care device is activated when a person holds the device and generates a second trigger signal when the vibration switch receives movement to drive the action part to act.

Description

Personal care device capable of being automatically started and shut down intelligently Technical Field The utility model relates to a personal care device, in particular to a personal care device capable of being automatically started and shut down intelligently. Background Personal care devices such as shavers, hair cutters, vibrissas, dental care appliances such as electric or manual toothbrushes, interdental cleaners or gum massaging devices, or skin treatment devices such as massaging devices or vibrators, and in the case of carrying a hand-held personal care apparatus such as an electric shaver in a bag, there is a concern that the hand-held personal care apparatus may be operated at will by inadvertently pressing an operating switch in the bag. Therefore, it is necessary to take a time to avoid an unintentional depression of the operation switch. In order to solve the above technical problems, for example, chinese patent CN204068921U discloses a portable personal care product with a self-locking function, which uses a self-locking circuit to increase the long time of identifying a button, uses a shift register and a locking/unlocking circuit to realize the self-locking and unlocking functions of the button, and prevents the user from touching the machine by mistake. However, by increasing the time, the operation is inconvenient in actual operation, and the mind of some people for use at once cannot be satisfied. Disclosure of utility model Aiming at the defects of the prior art, the utility model aims to provide a personal care device capable of intelligently and automatically switching on and switching off. In order to achieve the above purpose, the present utility model provides the following technical solutions: an intelligent automatic on-off personal care device, which comprises a holding part held by hand and an action part for processing human body, comprising: The metal sheet is arranged in the holding part, and the capacitance value generated when the metal sheet approaches to the hand of the human body changes according to whether the holding part is held or not; a control device electrically connected with the metal sheet for controlling the processing operation of the operation part, comprising: A grip detection unit that detects whether or not the grip unit is gripped based on a change in the capacitance value, and outputs a first trigger signal; A control signal output unit that outputs a control signal for allowing the operation unit to operate, based on whether or not the second trigger signal for allowing the operation unit to operate is received during the period when the first trigger signal is obtained; The vibration switch is arranged in the holding part and can generate a second trigger signal when vibrating, Wherein the second trigger signal is valid if and only if the first trigger signal is present. The metal sheet is disposed near any one of the surfaces in the circumferential direction of the grip portion. The holding detection part comprises a touch detection IC, and a detection circuit is arranged at the input end of the touch detection IC. The detection circuit comprises a resistor R1 connected with the input end, and the other end of the resistor R1 is grounded through a diac ZD 2. The control device is also provided with a power supply module. The control device is also provided with a motor driving module. The control signal output part outputs the control signal according to the second trigger signal in the duration of the first trigger signal, stops outputting the control signal when the first trigger signal disappears, and is not controlled by the second trigger signal in the duration of outputting the control signal. The utility model has the beneficial effects that the hand is close to the holding part to further change the capacitance value of the metal sheet to be used as the first trigger signal, so that the personal care device is activated when and only when a person holds the device, and the second trigger signal is generated when the vibration switch receives movement, so that the action part is driven to act, the whole control is more intelligent, the effect of taking and using can be realized, and the device can not be touched by mistake to start up when the capacitance of the metal sheet is not changed, and is convenient to carry.
