Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation and nursing technology, specifically relating to a novel rotatable foot torture device. Background Technology

[0002] Existing foot file devices typically include a handle, a foot-grinding component, a battery, a motor, and a circuit control module. The battery, motor, and circuit control module are usually housed in the handle, which is connected to the foot-grinding component at the top. The battery-powered motor drives the foot-grinding component to rotate, thereby scrubbing the skin on the soles of the feet. This can more effectively clean the soles of the feet and reduce fungal infections.

[0003] However, the handles of existing foot file devices are usually of a fixed shape. In this case, users need to adjust their wrist joints to file different areas or adjust their body posture to achieve the desired effect. For example, when filing their own feet, users typically bend their lower leg so that the soles of their feet face them, allowing the foot file to file the soles. If the user's lower leg is injured and cannot bend straight, they can only achieve the filing effect by twisting their wrist joint.

[0004] Therefore, it is necessary to design a new type of rotatable foot torturer to overcome the above problems. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a novel rotatable foot-grinding device, comprising a foot-grinding assembly, a motor assembly, a battery assembly, a control assembly, and a handle assembly. The handle assembly comprises a first handle component and a second handle component. The first handle component has a first rotary cutting surface with an annular protrusion. The annular protrusion has a threading hole inside and an annular groove around its periphery. The second handle component has a second rotary cutting surface that fits against the first rotary cutting surface. The second rotary cutting surface has an annular hole adapted to the annular groove, and the diameter of the annular hole is larger than the diameter of the annular groove, while the diameter of the annular hole is smaller than the outer diameter of the annular protrusion.

[0006] In some technical solutions, the thickness of the second rotary cutting surface is slightly smaller than the width of the annular groove, so that when the annular hole is connected to the annular protrusion, the first rotary cutting surface and the second rotary cutting surface can rotate while fitting together as closely as possible.

[0007] In some technical solutions, the height of the first rotary cutting surface and the second rotary cutting surface along the length direction of the handle assembly is equal to the diameter length of the handle assembly in the diameter direction.

[0008] In some technical solutions, the annular protrusion has a protruding structure along the diameter direction of the handle assembly.

[0009] In some technical solutions, the thickness of the protruding structure is the same as that of the annular protrusion.

[0010] In some technical solutions, the first handle component is located on one side of the battery assembly, and the second handle component is located near the foot grinding assembly.

[0011] In some technical solutions, the motor assembly is housed in the second handle component, and the battery assembly is housed in the first handle component.

[0012] In some technical solutions, a wire is provided between the battery assembly and the motor assembly, and the length of the wire is greater than the sum of the thicknesses of the first rotary cut surface and the second rotary cut surface.

[0013] This invention achieves the bending of the handle by setting a rotary cutting surface on the handle. During use, the user can not only hold the foot grinder handle in a fixed position in the scene space, but also reach the same foot grinding position by holding the handle in a way that deviates from the original position.

[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 scope of the present utility model.

[0022] It should be noted that when one element is considered to "drive" another element, it can be a direct drive to the other element or there may be an intervening element present. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this article are for illustrative purposes only.

[0023] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 As shown, the handles of existing foot file devices are typically cylindrical or have other relatively fixed shapes. This limits the user's ability to operate the handle at a specific angle, making it less adaptable to certain usage scenarios. Specifically, existing foot files usually include a handle, a grinding component, a battery, a motor, and a circuit control module. The battery, motor, and circuit control module are usually housed in the handle, with the top of the handle connected to the grinding component. The battery-powered motor drives the grinding component to rotate, thus exfoliating the soles of the feet and effectively cleaning them, reducing fungal infections. However, the handles of existing foot files are usually fixed in shape. In this case, users need to adjust their wrist joints to grind different areas or adjust their posture to achieve the desired effect. For example, when exfoliating their own feet, users typically bend their lower leg so that the soles of their feet face them. If a user's lower leg is injured and cannot bend straight, they must twist their wrist to achieve the desired effect. It should be noted that the above case of a lower leg injury is only one application scenario and does not represent all the scenarios that this utility model aims to address.

[0025] like Figure 2 As shown, the inventors discovered that the bending of the handle can be achieved by setting a rotary cutting surface on the handle. During use, the user can hold the handle of the foot file not only along the Y-axis in the scene space, but also in a direction away from the Y-axis, and still achieve the same foot file position.

[0026] The specific embodiments of this utility model are as follows:

[0027] like Figure 2-3As shown, this utility model provides a novel rotatable foot-grinding device 100: including a foot-grinding assembly 1, a motor assembly 2 connected to the foot-grinding assembly 1, a battery assembly 3 electrically connected to the motor assembly 2, a control assembly 4 electrically connected to the battery assembly 3 and the motor assembly 2, and a handle assembly 5 that can accommodate the motor assembly 2 and the battery assembly 3; characterized in that the handle assembly 5 includes a first handle part 51 and a second handle part 52, the first handle part 51 having a first rotary cutting surface 511, the first rotary cutting surface 511 having an annular protrusion 5111, the annular protrusion 5111 having a threading hole 5112 inside, and an annular groove 5 on the periphery. 113. The second handle component 52 is provided with a second rotary-cut surface 521 that fits against the first rotary-cut surface 511. The second rotary-cut surface 521 is provided with an annular hole 5211 that matches the annular groove 5113. The diameter of the annular hole 5211 is larger than the diameter of the annular groove 5113, while the diameter of the annular hole 5211 is smaller than the outer diameter of the annular protrusion 5111. The thickness of the second rotary-cut surface 521 is slightly smaller than the width of the annular groove 5113, so that when the annular hole 5211 is connected to the annular protrusion 5111, the first rotary-cut surface 511 and the second rotary-cut surface 521 can rotate while fitting together as closely as possible. It should be noted that the first rotary-cut surface 511 and the second rotary-cut surface 521 can be fitted with equal or unequal areas. In this embodiment, for the sake of aesthetics and simplicity, both are identical in shape.

[0028] like Figure 4 As shown, in this embodiment, to achieve a right-angle bend, the height H of the first rotary cutting surface 511 and the second rotary cutting surface 521 along the length direction of the handle is equal to the diameter length L in the diameter direction. Thus, after the first rotary cutting surface 511 and the second rotary cutting surface 521 are rotated and bent, the first handle component 51 and the second handle component 52 form a right angle. Figure 2 As shown, when the handle of the foot file 100 is not bent and it is used in a straight cylindrical form, the user has an angle to operate the foot file 100 in the Y-axis direction in the scene space. When it is used in a twisted form, the user has an angle to operate the foot file 100 in the X-axis direction. Both angles can simultaneously enable the foot file component 1 to grind and wash the foot on the designated position of the sole.

[0029] like Figure 5As shown, in this embodiment, the annular protrusion 5111 is further provided with a protruding structure 51111 along the diameter direction of the handle assembly 5, and the thickness of the protruding structure 51111 is the same as that of the annular protrusion 5111. This is to further prevent the annular protrusion 5111 on the first rotary cutting surface 511 from disengaging from the annular hole 5211 due to excessive external force when they are engaged.

[0030] It should be noted that the first handle component 51 in this utility model can be located near the foot-grinding assembly 1, that is, near the top of the handle assembly 5, and correspondingly, the second handle component 52 is located on one side of the battery assembly 3, that is, near the bottom of the handle assembly 5; or the first handle component 51 can be located on one side of the battery assembly 3, that is, near the bottom of the handle assembly 5, and correspondingly, the second handle component 52 is located near the foot-grinding assembly 1, that is, near the top of the handle assembly 5. Figure 3 As shown, in this embodiment, the first handle component 51 is positioned near the top of the handle assembly 5, and the second handle component 52 is positioned near the bottom of the handle assembly 5. Thus, the annular protrusion 5111 is located in the upper half of the handle assembly 5.

[0031] In existing foot grinders 100, the battery assembly 3 and motor assembly 2 are typically standard modules, and this embodiment is no exception, as this saves costs by eliminating the need for customized modules. Figure 3 As shown, the motor assembly 2 of the foot file 100 is housed in the first handle component 51, and the battery assembly 3 is housed in the second handle component 52. Generally, the battery assembly 3 has a greater mass than the motor assembly 2. After rotation, if the battery assembly 3 is located in the first handle component 51, it will result in a larger mass distribution in the first handle component 51, leading to a top-heavy result. This will worsen the user's grip on the foot file 100, and at higher motor speeds, it may become difficult to control the foot file 1. Simultaneously, the length of the wire between the battery assembly 3 and the motor is greater than the combined thickness of the first rotary cut surface 511 and the second rotary cut surface 521. This ensures that during rotation caused by the first rotary cut surface 511 and the second rotary cut surface 521, the wire will not break due to excessively short wires between the battery assembly 3 and the motor assembly 2.

[0032] The above are only some embodiments of this utility model. It should be noted that for those skilled in the art, other modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
