[0008] Specifically, a capacitive touch button is provided on the nail clipper body, and the capacitive touch button is used to connect or disconnect the cutter head driving circuit according to a touch signal.

[0011] S200, analyzing the pressure detection signal to obtain pressure data, and then calculating the pressure change amplitude data within a first preset time interval, and determining whether the pressure change amplitude data is greater than or equal to a first preset threshold;

[0012] S300: Determine whether to control the electric nail clipper head to start according to the determination result.

[0013] Specifically, judging whether to control the electric nail clipper head to start according to the judgment result includes:

[0014] If the pressure change amplitude data is greater than or equal to the first preset threshold, the electric nail clipper head is controlled to start;

[0015] If the pressure change amplitude data is less than the first preset threshold value, the electric nail clipper head is not controlled to start.

[0016] Specifically, the method further includes:

[0017] If a closing signal of the first start-stop switch provided on the electric nail clipper is obtained, the capacitive touch button is used to determine whether a touch signal is obtained. If so, the electric nail clipper head is controlled to start; if not, the electric nail clipper head is not controlled to start.

[0018] Specifically, the method further includes:

[0030] Compared with the prior art, the comprehensive effects brought by the present invention include:

[0031] (1) The present application sets a push trigger structure between the cutter head and the nail clipper body. During normal use, the cutter head needs to be pressed with a certain force so that the push trigger structure connects to the cutter head drive circuit, and the cutter head can move to trim the nails. When the force of pressing with the lips or tongue is not enough to trigger the push trigger structure to connect to the cutter head drive circuit, the cutter head will not move, thereby effectively protecting children and avoiding accidental injuries.

[0032] (2) The cutter head assembly is designed as a push-type movable structure, which is linked to the control switch and transmits the switch signal to the first control unit. When the cutter head is pressed to move, the fixed structure drives the linked reset structure to move, and the cutter head drive circuit drives the cutter head to move. Children have less strength, so it is prevented that the child's tongue or lips touch the cutter head and cause injury.

[0033] (3) A pressure sensor is designed at the blade head. When in use, the finger needs to press the blade head with a certain force to trigger the signal change of the pressure sensor. The second control unit detects that the signal change reaches a certain amplitude before driving the blade head to rotate. The second control unit analyzes the difference in the amplitude of the pressure sensor signal change to distinguish between finger pressure or lip or tongue pressure, thereby protecting the lips and tongue from contact with the blade head.

[0041] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0042] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0043] See also Figure 1-6 The present invention provides an electric nail clipper, comprising:

[0044] The invention comprises a nail clipper body, on which a cutter head is arranged, and a pressure detection device is provided between the cutter head and the nail clipper body. The pressure detection device switches on or off a cutter head driving circuit according to the pressure condition of the cutter head.

[0045] Specifically, a capacitive touch button is provided on the nail clipper body, and the capacitive touch button is used to connect or disconnect the cutter head driving circuit according to a touch signal.

[0046] like Figures 1 to 3 As shown, an electric nail clipper with a protection mechanism includes a nail clipper body 1, on which a cutter head 2 is arranged, and a pressure detection device is provided between the cutter head 2 and the nail clipper body 1. The pressure detection device connects or disconnects the cutter head drive circuit according to the pressure condition of the cutter head 2.

[0047] The present application sets a pressure detection device between the cutter head and the nail clipper body. During normal use, the cutter head needs to be pressed with a certain force so that the pressure detection device connects to the cutter head drive circuit to realize the movement of the cutter head to trim the nails. When the force of pressing with the lips or tongue is not enough to trigger the pressure detection device to connect to the cutter head drive circuit, the cutter head will not move, thereby effectively protecting children and avoiding accidents and injuries.

[0048] In other preferred embodiments, the pressure detection device includes a fixed structure 3 for fixing the cutter head 2 and a linkage reset structure 4 for linkage with the fixed structure 3. The cutter head 2 is arranged on the fixed structure 3. The fixed structure 3 is displaced along with the cutter head 2 according to the force applied to the cutter head 2, thereby driving the linkage reset structure 4 to move. The linkage reset structure 4 has a control connection relationship with a control switch for controlling the cutter head drive circuit arranged in the nail clipper body 1, and the action of the linkage reset structure 4 is associated with the switching action of the control switch.

[0049] The cutter head assembly is designed as a push-active structure, which is linked to the control switch and transmits the switch signal to the first control unit. When the cutter head is pressed to move, the fixed structure 3 drives the linked reset structure 4 to move, and the cutter head drive circuit can drive the cutter head to move. Children have less strength, so it is prevented that the tongue or lips of children touch the cutter head and cause injuries.

[0050] In this embodiment, the linkage reset structure 4 has a reset structure. When the force on the cutter head 2 disappears, the linkage reset structure 4 is pushed by the reset structure to reset, thereby driving the cutter head 2 on the fixed structure 3 to reset.

[0051] In this embodiment, the nail clipper body 1 further includes a first power supply 9 and a first control unit. The first power supply 9, the first control unit and the control switch are connected to form a cutter head driving circuit.

[0052] The control switch is actuated to connect or disconnect the first power source 9 and the first control unit, thereby determining whether the cutter head 2 is actuated according to the pressure condition of the control switch.

[0053] In this embodiment, the blade drive circuit further includes a first start-stop switch 7, and the first start-stop switch 7 is connected to the first control unit signal.

[0054] Preferably, a first power switch is connected between the first power supply 9 and the first control unit. The first power switch can be a mechanical switch type, such as a toggle switch, a sliding switch, a rocker switch, etc., or other key switch types with equivalent functions. During use, the first power switch is first turned on / pressed, and the product is in a standby state. If the user turns on / presses / touches the first start-stop switch 7, the nail presses the cutter head 2, the nail clipper body 1 will start to work, and the cutter head 2 will start to rotate. The first start-stop switch 7 is a capacitive touch button in a preferred embodiment.

[0055] Specifically, the capacitive touch button is applied to a capacitive touch button circuit, the second control unit further includes a second detection signal input terminal TOUCH IN, and the capacitive touch button circuit includes:

[0056] The second MCU chip U2, the tenth resistor R10 and the capacitive touch button TOUCH, the second MCU chip U2 includes a signal input end and a signal output end, the signal input end of the second MCU chip U2 is pin 3 of the second MCU chip U2, the signal output end of the second MCU chip U2 is pin 1 of the second MCU chip U2, the capacitive touch button TOUCH is connected to the signal input end of the second MCU chip U2 through the tenth resistor R10, and the signal output end of the second MCU chip is connected to the second detection signal input end TOUCH IN.

[0057] It should be noted here that the model of the second MCU chip U2 of the present invention is AS9601D2.

[0058] In other preferred embodiments, the pressure detection device is a pressure sensor RP1. Preferably, the pressure sensor RP1 is a thin film pressure sensor.

[0059] The present application is designed with a pressure sensor RP1 at the blade 2; during normal use, the finger needs to press the blade 2 component with a certain force to trigger the signal change of the pressure sensor RP1, and the control unit detects that the signal change reaches a certain amplitude before driving the blade 2 to rotate. The texture of lips or tongue is quite different from that of fingers, and is relatively soft, especially for children. The signal change amplitude generated by pressing the pressure sensor RP1 with lips or tongue is different from the signal change amplitude generated by finger touching and pressing, and is usually smaller. The control unit distinguishes between finger pressing or lip or tongue pressing by the difference in the different signal change amplitudes of the pressure sensor RP1, thereby protecting the lips and tongue from contacting the blade 2.

[0060] Through the above solution, the possibility that young children start the nail clipper body 1 by themselves can be effectively avoided, thereby improving the safety of the product for children.

[0061] In this embodiment, the nail clipper body 1 also includes a second power supply and a second control unit. The second power supply, the second control unit and the pressure sensor RP1 are connected to form a cutter head drive circuit. The cutter head drive circuit also includes a second start-stop switch, and the second start-stop switch is connected to the second control unit signal.

[0062] See also Figure 4 Further, the second control unit includes a first detection signal input terminal PRESS ADC, the pressure detection device includes a pressure sensor RP1 detection circuit, and the pressure sensor RP1 detection circuit includes:

[0063] A pressure sensor RP1, an eleventh resistor R11 and an eleventh capacitor C11, one end of the pressure sensor RP1 is electrically connected to one end of the eleventh resistor R11, one end of the eleventh capacitor C11 and the first detection signal input terminal PRESS ADC respectively, and the other end of the eleventh resistor R11 and the other end of the eleventh capacitor C11 are grounded.

[0064] A second power switch is set to be connected between the second power supply and the second control unit. During use, first, the second power switch is long pressed to turn on the product, and the nail clipper body 1 is in standby state 1. Subsequently, the user needs to keep pressing or touching the second start-stop switch to put the product into standby state 2. At this time, if the user presses the cutter head 2 with a finger, the pressure sensor RP1 assembled on the surface of the cutter head 2 transmits a signal to the second control unit. After the second control unit detects that the amplitude of the signal change reaches a certain value requirement, the nail clipper body 1 will start to work, and the cutter head 2 will start to rotate for trimming.

[0065] If the second start-stop switch is lifted or not touched, the blade head 2 will stop rotating immediately. Preferably, the second start-stop switch can be a mechanical touch key switch or a touch key switch, or other key switch types with equivalent functions. If the amplitude of the signal change of the pressure sensor RP1 on the surface of the blade head 2 does not reach a certain numerical requirement, the blade head 2 will also stop rotating immediately.

[0066] In this embodiment, an arc groove 5 is provided at one end of the nail clipper body 1, a nail opening 6 is provided on the groove surface of the arc groove 5, the cutter head 2 is provided on the inner side of the nail opening 6, and a second start-stop switch is provided at the top of the nail clipper body 1 for easy long pressing or touching, and the second power switch is provided on the side of the nail clipper body 1.

[0067] Preferably, a stopper 8 is provided on the groove surface of the arc groove 5, and the stopper 8 is installed above the nail opening 6. A cavity is provided in the stopper 8, and at least one lighting lamp is installed in the cavity. The lighting lamp is connected to the control unit signal. The stopper 8 and the lighting lamp are provided to provide lighting for the nail opening 6, so as to facilitate better trimming of nails and check whether the nails are trimmed neatly during normal use; preferably, the lighting lamp is turned on or off synchronously with the operating state of the cutter head 2.

[0068] See also Figure 5 The present invention provides another embodiment, which provides a method for starting and stopping a cutter head of an electric nail clipper, and the method for starting and stopping a cutter head of an electric nail clipper comprises:

[0069] S100, obtaining a closing signal of a first start-stop switch provided on the electric nail clipper at a first preset time interval, and determining whether a closing signal of the first start-stop switch provided on the electric nail clipper is obtained; if so, obtaining a pressure detection signal at a first preset time interval using a pressure detection device provided between the cutter head and the nail clipper body.

[0070] It should be noted here that before step S100, the first preset threshold, the first preset time interval, the second preset threshold, the second preset time interval, and the third preset threshold are pre-set in the second control unit.

[0071] It can be understood that the first preset threshold, the first preset time interval, the second preset threshold, the second preset time interval, and the third preset threshold can be specifically set according to the actual needs of the user of the present invention. The present invention does not impose specific restrictions on the values ​​of the first preset threshold, the first preset time interval, the second preset threshold, the second preset time interval, and the third preset threshold, as long as they are applicable to the method for starting and stopping the cutter head of an electric nail clipper proposed in the present invention.

[0072] Preferably, the present invention sets the first preset threshold to 5 kilograms of pressure applied on an area of ​​1 square centimeter, the present invention sets the first preset time interval to 1 second, the present invention sets the second preset time interval to 0.5 seconds, the present invention sets the second preset threshold to 2 seconds, and the present invention sets the third preset threshold to 3 kilograms of pressure applied on an area of ​​1 square centimeter. The settings of the above parameters are obtained by the technicians of the present invention through a large number of tests, and can well implement the start and stop method of the electric nail clipper head of the present invention.

[0073] S200, analyzing the pressure detection signal to obtain pressure data, and then calculating the pressure change amplitude data within a first preset time interval, and determining whether the pressure change amplitude data is greater than or equal to a first preset threshold;

[0074] S300: Determine whether to control the electric nail clipper head to start according to the determination result.

[0075] Specifically, judging whether to control the electric nail clipper head to start according to the judgment result includes:

[0076] If the pressure change amplitude data is greater than or equal to the first preset threshold, the electric nail clipper head is controlled to start;

[0077] If the pressure change amplitude data is less than the first preset threshold value, the electric nail clipper head is not controlled to start.

[0078] Specifically, the method further includes:

[0079] If a closing signal of the first start-stop switch provided on the electric nail clipper is obtained, the capacitive touch button is used to determine whether a touch signal is obtained. If so, the electric nail clipper head is controlled to start; if not, the electric nail clipper head is not controlled to start.

[0080] Specifically, the method further includes:

[0081] If the pressure change amplitude data is greater than or equal to the first preset threshold, calculate the duration of the pressure change amplitude data being greater than or equal to the first preset threshold based on the first preset time interval data, determine whether the duration is greater than or equal to the second preset threshold, and determine whether to control the electric nail clipper head to start based on the judgment result.

[0082] Specifically, the method further includes:

[0083] If the duration is greater than or equal to a second preset threshold, controlling the electric nail clipper head to start;

[0084] If the duration is less than the second preset threshold, the electric nail clipper head is not controlled to start.

[0085] It can be understood that the present invention controls the electric nail clipper head to start only when the duration is greater than or equal to the second preset threshold, which further prevents accidental touching by infants and young children, and further improves the safety and reliability of the present invention.

[0086] Specifically, the method further includes:

[0087] After the cutting head of the electric nail clipper is started, a pressure detection device arranged between the cutting head and the nail clipper body is used to obtain a pressure detection signal according to a second preset time interval, and the pressure detection signal is analyzed to obtain pressure data, and then the pressure change amplitude data within the second preset time interval is calculated to determine whether the pressure change amplitude data is greater than or equal to a third preset threshold value, and whether to control the cutting head of the electric nail clipper to stop is determined based on the judgment result.

[0088] Specifically, the method further includes:

[0089] If the pressure variation amplitude data is greater than or equal to the third preset threshold value, the cutting head of the electric nail clipper is controlled to stop.

[0090] Specifically, the method further includes:

[0091] If the pressure change amplitude data is less than the third preset threshold value, the electric nail clipper head is not controlled to stop.

[0092] It can be understood that when the cutter head of the electric nail clipper is started, the present invention greatly improves the safety and reliability of the present invention by shortening the first preset time interval to the second preset time interval, thereby increasing the detection frequency. Moreover, since the detection frequency is increased, the present invention utilizes the third preset threshold for detection, which further improves the reliability and availability of the detection of the present invention and greatly improves the user experience.
