[0001] The utility model relates to the technical field of electric nail clippers, in particular to an electric nail clipper with a protection mechanism. Background Art

[0002] Electric nail clippers are a kind of daily necessities for personal care, which are driven by electricity to help users trim their nails. Existing electric nail clippers are mainly composed of a shell, a motor and a cutting shaft. After the nail is inserted into the shell through the nail inlet, the nail is cut by the blade, thereby trimming the nail.

[0003] Currently, the control of electric nail clippers is relatively simple. They can be started by simply pressing the power button. After the electric nail clippers are started, it is dangerous for young children to use them or play with them alone. Known dangerous cases are all cases where the lips or tongues were accidentally injured by the cutter head. Utility Model Content

[0004] In view of the shortcomings of the prior art, an electric nail clipper with a protection mechanism is proposed, which solves the problem in the above background technology that after the electric nail clippers are started, it is dangerous for young children to use or play alone.

[0005] In order to achieve the above purpose, the utility model proposes the following technologies to achieve it:

[0006] An electric nail clipper with a protection mechanism comprises a nail clipper body, a cutter head is arranged on the nail clipper body, a press trigger structure is provided between the cutter head and the nail clipper body, and the press trigger structure connects or disconnects the cutter head drive circuit according to the pressure of the cutter head.

[0007] Furthermore, the press-trigger structure includes a fixed structure for fixing the cutter head and a linked reset structure for linking with the fixed structure, the cutter head is arranged on the fixed structure, and the fixed structure is displaced with the cutter head according to the force applied to the cutter head, thereby driving the linked reset structure to move, wherein the linked reset structure has a control connection relationship with a control switch for controlling the cutter head drive circuit arranged in the nail clipper body, and the action of the linked reset structure is associated with the switching action of the control switch.

[0008] Furthermore, the linkage reset structure has a reset structure. When the force on the cutter head disappears, the linkage reset structure is pushed by the reset structure to reset, thereby driving the cutter head on the fixed structure to reset.

[0009] Furthermore, the nail clipper body also includes a first power supply and a first control unit, and the first power supply, the first control unit and the control switch are connected to form a cutter head driving circuit.

[0010] Furthermore, the blade drive circuit also includes a first start-stop switch, and the first start-stop switch is connected to the first control unit signal.

[0011] Furthermore, the press trigger structure is a pressure sensor.

[0012] Furthermore, the pressure sensor is a thin film pressure sensor.

[0013] Furthermore, the nail clipper body also includes a second power supply and a second control unit, and the second power supply, the second control unit and the pressure sensor are connected to form a cutter head driving circuit.

[0014] Furthermore, the blade drive circuit also includes a second start-stop switch, and the second start-stop switch is connected to the second control unit signal.

[0015] Compared with the prior art, the comprehensive effects brought by the utility model include:

[0016] (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.

[0017] (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.

[0018] (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.

[0023] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the utility model.

The orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "top", etc. is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation to the utility model.

[0025] 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 press-trigger structure is provided between the cutter head 2 and the nail clipper body 1. The press-trigger structure connects or disconnects the cutter head drive circuit according to the pressure of the cutter head 2.

[0026] The present application sets a press-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 press-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 press-trigger structure to connect to the cutter head drive circuit, the cutter head will not move, thereby effectively protecting children and avoiding accidents and injuries.

[0027] Embodiment 1:

[0028] In this embodiment, the press-trigger structure includes a fixed structure 3 for fixing the cutter head 2 and a linked reset structure 4 for linking with the fixed structure 3. The cutter head 2 is set on the fixed structure 3. The fixed structure 3 moves with the cutter head 2 according to the force applied to the cutter head 2, thereby driving the linked reset structure 4 to move. The linked reset structure 4 has a control connection relationship with a control switch for controlling the cutter head drive circuit set in the nail clipper body 1, and the action of the linked reset structure 4 is associated with the switching action of the control switch.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] Preferably, a first power switch is connected between the first power source 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 starts to work, and the cutter head 2 starts to rotate.

[0035] Embodiment 2:

[0036] In this embodiment, the press trigger structure is a pressure sensor, and preferably, the pressure sensor is a thin film pressure sensor.

[0037] The present application is designed with a pressure sensor 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, 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 with lips or tongue is different from that generated by pressing with fingers, 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, thereby protecting the lips and tongue from contacting the blade 2.

[0038] 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.

[0039] 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 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.

[0040] A second power switch is set to be connected between the second power supply and the second control unit. During use, the second power switch is first 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 signal assembled on the surface of the cutter head 2 is transmitted 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.

[0041] 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 change of the pressure sensor signal on the surface of the blade head 2 does not reach a certain numerical requirement, the blade head 2 will also stop rotating immediately.

[0042] 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.

[0043] 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.
