Description

Technical Field

[0001] This utility model relates to the field of touch-controlled electric nail clipper design technology, specifically to a touch-controlled electric nail clipper and its control circuit. Background Technology

[0002] Most electric nail clippers on the market are relatively simple to control; for example, they can be started by pressing the power button. Even if some products have a child lock mechanism, it is still impossible to completely prevent young children from turning them on by themselves. Given the current structure of the electric nail clipper head, it is dangerous for young children to use or play with it alone after it has been started. Known cases of accidents have involved accidental cuts to the lips or tongue from the blade.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a touch-controlled electric nail clipper and its control circuit to solve the technical problems existing in the related technologies.

[0005] To achieve the above-mentioned technical objectives, according to the first aspect of this utility model, the present utility model adopts the following technical solution: a control circuit for a touch-controlled electric nail clipper is provided, the circuit comprising:

[0006] The system includes a main control MCU circuit, a touch detection circuit, and an electric nail clipper head motor drive circuit. The touch detection circuit is communicatively connected to the main control MCU circuit, and the main control MCU circuit is controllably connected to the electric nail clipper head motor drive circuit.

[0007] Specifically, the circuit also includes:

[0008] A start button circuit is provided, which includes a start button and is electrically connected to the main control MCU circuit.

[0009] Specifically, the electric nail clipper head motor drive circuit includes a motor control signal input terminal. The electric nail clipper head motor drive circuit is connected to the electric nail clipper head motor control. The electric nail clipper head motor drive circuit is used to start or stop the electric nail clipper head motor under the control of the motor control signal.

[0010] Specifically, the main control MCU circuit includes:

[0011] The first MCU chip includes a detection signal input terminal and a motor control signal output terminal. The motor control signal output terminal of the first MCU chip is electrically connected to the motor control signal input terminal of the motor drive circuit. The motor control signal output terminal of the first MCU chip is used to output motor control signals.

[0012] Specifically, the touch detection circuit includes:

[0013] Capacitive touch button circuit.

[0014] Specifically, the capacitive touch button circuit includes:

[0015] The second MCU chip, the tenth resistor, and the capacitive touch button are described. The detection signal input terminal includes a second detection signal input terminal. The second MCU chip includes a signal input terminal and a signal output terminal. The capacitive touch button is connected to the signal input terminal of the second MCU chip through the tenth resistor. The signal output terminal of the second MCU chip is connected to the second detection signal input terminal.

[0016] According to another aspect of the present invention, the present invention also provides a touch-controlled electric nail clipper, which employs the control circuit of the above-mentioned touch-controlled electric nail clipper. The touch-controlled electric nail clipper includes an electric nail clipper body, on which a capacitive touch area for sensing human touch actions is provided, and a capacitive touch button is provided on the capacitive touch area.

[0017] Specifically, the capacitive touch area is located on the electric nail clipper body at an ergonomic finger gripping position. There are two finger gripping positions, located on two surfaces of the electric nail clipper body respectively, and the capacitive touch area is located at at least one of the finger gripping positions.

[0019] Specifically, when the electric nail clipper body is a regular shape, the positions where two people hold the electric nail clipper body with their fingers are on the same straight line as the geometric center of the electric nail clipper body.

[0020] Beneficial effects:

[0021] In addition to the start button circuit, this invention also includes a touch detection circuit. After the start button circuit powers on the electric nail clippers, the clippers enter a standby state, where the clippers head does not start. The clippers head motor only rotates when the touch detection circuit detects a touch signal.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] To effectively solve the above problems, this utility model provides a control circuit for a touch-controlled electric nail clipper, which will be described in detail below.

[0026] According to an embodiment of this utility model, a control circuit for a touch-controlled electric nail clipper is provided. Please refer to [link / reference]. Figure 1 ,include:

[0027] The system includes a main control MCU circuit, a touch detection circuit, and an electric nail clipper head motor drive circuit. The touch detection circuit is communicatively connected to the main control MCU circuit, and the main control MCU circuit is controllably connected to the electric nail clipper head motor drive circuit.

[0028] Specifically, the circuit also includes:

[0029] A start button circuit is provided, which includes a start button SW1 and is electrically connected to the main control MCU circuit.

[0030] It should be noted that the start button circuit is existing technology. The start button SW1 is used to turn on the electric nail clipper and put it into standby mode, or to turn off the electric nail clipper. This utility model does not make specific requirements on the mechanical structure and type of the start button SW1, as long as it can realize the switching between standby mode and off mode of the electric nail clipper.

[0031] Specifically, the electric nail clipper head motor drive circuit includes a motor control signal input terminal. The electric nail clipper head motor drive circuit is connected to the electric nail clipper head motor control. The electric nail clipper head motor drive circuit is used to start or stop the electric nail clipper head motor under the control of the motor control signal.

[0032] Specifically, the main control MCU circuit includes:

[0033] The first MCU chip includes a detection signal input terminal and a motor control signal output terminal. The motor control signal output terminal of the first MCU chip is electrically connected to the motor control signal input terminal of the motor drive circuit. The motor control signal output terminal of the first MCU chip is used to output motor control signals.

[0034] Specifically, the touch detection circuit includes at least one of the following:

[0035] Capacitive touch button circuit.

[0038] It should be noted that the model number of the second MCU chip U2 in this invention is AS9601 D2.

[0039] It is understood that this invention, in addition to the start button circuit, also includes a touch detection circuit. After the start button circuit powers on the electric nail clippers, the clippers are in standby mode, where the clippers head does not start. The clippers head motor only rotates when the touch detection circuit detects a touch signal. If the touch detection circuit fails to detect a touch signal, the clippers head motor immediately stops rotating. This design effectively reduces the probability of young children starting the product independently, thus improving the safety of the product for children handling electric nail clippers.

[0040] Please see Figure 2 In other preferred embodiments of this utility model, this utility model also provides a touch-controlled electric nail clipper, which adopts the control circuit of the touch-controlled electric nail clipper described above. The touch-controlled electric nail clipper includes an electric nail clipper body 1, on which a capacitive touch area 3 for sensing human touch actions is provided, and a capacitive touch button is provided on the capacitive touch area 3.

[0041] Specifically, the electric nail clipper body 1 has a nail trimming head 4. The electric nail clipper body 1 is a housing, and the head 4 is mounted on the housing and located at one end of the electric nail clipper body 1. The electric nail clipper body 1 has at least one capacitive touch area 3, that is, the capacitive touch area 3 is located on the outside of the housing of the electric nail clipper body 1. A capacitive touch button is provided on the capacitive touch area 3. The electric nail clipper body 1 contains a main control MCU circuit and an electric nail clipper head motor drive circuit for driving the movement of the head 4. The electric nail clipper head motor drive circuit is connected to the head 4 and includes a motor that drives the head 4 to rotate. The electric nail clipper head motor drive circuit and the capacitive touch button are respectively connected to the main control MCU circuit. The electric nail clipper body 1 is also equipped with a power switch 2 for turning on and a power supply (battery).

[0042] Specifically, the capacitive touch area 3 is located on the electric nail clipper body 1 at an ergonomic finger gripping position. This position depends on the shape of the electric nail clipper body 1, that is, when the user picks up the electric nail clipper body 1, the capacitive touch area 3 corresponds to the finger gripping position.

[0043] As a technical optimization of this utility model, there are two finger pinching positions, which are respectively located on two corresponding surfaces of the electric nail clipper body 1. The capacitive touch area 3 is located at at least one of the finger pinching positions, for example, corresponding to the user's thumb pinching position or the index finger pinching position.

[0044] As a technical optimization of this utility model, the positions where the two people's fingers are pinching the nail clipper are on the same straight line as the center of gravity of the electric nail clipper body 1.

[0045] As a technical optimization of this utility model, when the electric nail clipper body 1 is a regular shape, the positions where two people hold the electric nail clipper body 1 with their fingers are on the same straight line as the geometric center of the electric nail clipper body 1.

[0046] As a technical optimization of this utility model, the finger gripping positions on the two corresponding surfaces of the electric nail clipper body 1 are aligned with the center of gravity of the electric nail clipper body 1. This facilitates gripping by the user and provides a more comfortable gripping effect. Furthermore, the capacitive touch area 3 is located at this gripping position, serving to guide the user's gripping action.

[0047] As a technical optimization of this utility model, when the electric nail clipper body 1 has a regular shape, the positions where the user's fingers pinch the clipper on the two corresponding surfaces of the electric nail clipper body 1 are on the same straight line as the geometric center of the electric nail clipper body 1. For example, when the electric nail clipper body 1 is regularly symmetrical and the main body is in the shape of a rectangular cube, the position of the capacitive touch area 3 guides the user's pinching, and the user's finger pinching position is on the same straight line as the geometric center of the electric nail clipper body 1, which can effectively improve the user's comfort.

[0048] As a technical optimization of this utility model, the line connecting the gripping positions of the fingers on the two corresponding surfaces of the electric nail clipper body 1 is perpendicular or parallel to the direction of the blade head 4. During operation, gripping the electric nail clipper body 1 effectively controls the direction in which the blade head 4 trims the nails, and makes it easy for the user to observe the position of the blade head 4.

[0049] As a technical optimization of this utility model, the electric nail clipper body 1 is provided with a shallow groove corresponding to the capacitive touch area 3. The capacitive touch area 3 is formed in the shallow groove. The shallow groove can effectively correspond to the capacitive touch area 3 when the user pinches it, and at the same time, it also plays an effective anti-slip role.

[0050] As a technical optimization of this utility model, the capacitive touch area 3 of the electric nail clipper body 1 is provided with a fingerprint pattern shape coating. The fingerprint pattern shape coating serves as an identifier, making it easy for users to quickly locate and use the capacitive touch area 3.
