Description

Technical Field

[0001] This utility model belongs to the technical field of electric armor grinders, and specifically relates to an electric armor grinder with a force-sensing switch. Background Technology

[0002] Fingernails are a part of the human body and, like hair, they continue to grow. Overly long nails can cause inconvenience in daily life, so they need to be trimmed regularly to keep them at an appropriate length.

[0003] In the past, nail trimming was usually done manually, involving first trimming the nail tips with nail clippers and then filing them with a nail file, a time-consuming and laborious process. Based on this, electric nail filers have emerged in current technology. These typically include a control switch, a control circuit board, a motor, and nail file blades. When in operation, the nail filer is activated by the control switch, the control circuit board controls the motor, and the motor drives the nail file blades to rotate, thus achieving automatic nail trimming.

[0004] However, existing electric nail grinders typically use traditional physical buttons or touch buttons for their control switches. Traditional physical buttons are difficult to integrate with the housing, and waterproofing often requires complex structures, resulting in a less aesthetically pleasing overall switch panel. Touch switches require the finger to hold the button continuously for the grinder to operate; once the finger is released, the grinder stops working. Holding the grinder in one position for an extended period can lead to monotonous grip and finger fatigue. Utility Model Content

[0005] To solve the above problems, the primary objective of this utility model is to provide an electric armor grinder with a force-sensitive switch, which makes the switch more convenient.

[0006] Another objective of this utility model is to provide an electric nail grinder with a force-sensing switch, which facilitates the integration of the nail grinder body, improves waterproofing, and enhances aesthetics.

[0007] Another objective of this invention is to provide an electric nail grinder with a force-sensitive switch, which offers more diverse grip options and greater comfort.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows:

[0009] This utility model provides an electric nail grinder with a force-sensing switch, comprising: a nail grinder body, a control circuit board, a nail grinding assembly, and a force sensor.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] To achieve the above objectives, the technical solution of this utility model is as follows:

[0023] See Figure 1-5 This embodiment provides an electric nail grinder with a force-sensing switch, including: a nail grinder body 1, a control circuit board, a nail grinding assembly 2, and a force sensor 3. The control circuit board is disposed inside the nail grinder body 1, and the force sensor 3 is connected to the control circuit board. A first mounting groove 4 with an upper opening is provided on the nail grinder body 1, and the nail grinding assembly 2 is disposed in the first mounting groove 4, with the upper part of the nail grinding assembly 2 exposed outside the nail grinder body 1. A second mounting groove 5 is provided on the bottom wall of the first mounting groove 4, and the force sensor 3 is disposed in the second mounting groove 5, with the force sensor 3 attached to the bottom of the nail grinding assembly 2.

[0024] In this embodiment, the nail grinder body 1 includes a housing 11 for mounting accessories such as a control circuit board, a nail grinding assembly 2, and a force sensor 3; the nail grinding assembly 2 is used to grind and repair nails; the force sensor 3 is used to sense whether there are nails on the nail grinding assembly 2, thereby cooperating with the control circuit board to realize the switching on and off of the electric nail grinder.

[0025] In this embodiment, when the electric nail grinder is in operation, the user presses their nail onto the nail grinding component 2, transmitting the pressure to the force sensor 3. This triggers a slight deformation in the force sensor 3, which detects the applied pressure by sensing its own deformation. The force sensor 3 then transmits the detection signal to the control circuit board, which controls the nail grinding component 2 to operate, thus enabling the electric nail grinder to automatically start and operate. When the user's nail leaves the nail grinding component 2, the force transmitted to the force sensor 3 disappears, and the electric nail grinder stops working. This design allows for automatic switching of the electric nail grinder via force sensing, making switching more convenient. Compared to conventional physical or touch buttons, it eliminates the need for a switch button on the housing 11 of the nail grinder body 1, allowing for flexible material selection to achieve a seamless, integrated design, better waterproofing, and a more aesthetically pleasing appearance. Furthermore, unlike touch buttons, users do not need to constantly press the touch button during use, allowing for more flexible hand grip positions and greater comfort.

[0026] Furthermore, the force sensor 3 is fitted against the bottom wall of the second mounting groove 5, and the bottom wall of the second mounting groove 5 is provided with a deformation avoidance groove 6. In this application, the deformation avoidance groove 6 enables the force sensor 3 to form a deformation space on the side near the bottom wall of the second mounting groove 5. When the force sensor 3 is subjected to pressure from the side of the armor grinding assembly 2, it can deform more easily and detect the deformation pressure more easily, making the triggering and opening of the electric armor grinder more sensitive.

[0027] Furthermore, the nail grinding assembly 2 includes a motor 21, a nail grinding blade 22, and a blade sheath 23. The motor 21 and the blade sheath 23 are disposed within the first mounting slot 4. The motor 21 is connected to the control circuit board. The nail grinding blade 22 is rotatably connected within the blade sheath 23 and connected to the output end of the motor 21. The blade sheath 23 also has a nail grinding groove 24 for placing the nail, which is exposed outside the nail grinder body 1. In this embodiment, when using the device, the user places the nail in the nail grinding groove 24 and presses down on the nail grinding blade 22. After the force sensor 3 senses the pressure of the nail, the control circuit board controls the motor 21 to work. The motor 21 drives the nail grinding blade 22 to rotate within the blade sheath 23, thereby achieving nail grinding and repair.

[0028] In this embodiment, the force sensor 3 can be located directly below the motor 21 or directly below the blade sheath 23. In both of these methods, when the nail is placed in the nail grinding groove 24 and the nail grinding blade 22 is pressed down, the pressing force can be sensitively transmitted to the force sensor 3, thereby realizing a sensitively activated electric nail grinder.

[0029] Furthermore, the nail file 22 is a rod-shaped spiral file that can be rotated to file and repair nails.

[0030] Furthermore, the electric nail grinder also includes a gear adjustment module, which is electrically connected to the control circuit board. In this embodiment, the gear adjustment module can adjust the speed of the motor 21 through the main control chip based on the force value detected by the force sensor 3, thereby realizing the adjustment of the gear of the electric nail grinder. This allows the electric nail grinder to adapt to the grinding intensity according to the user's pressing pressure, making it more convenient to use. It should be noted that gear adjustment is a commonly used existing technology in electronic products, and its specific implementation details are not described in detail in this application.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
