Abstract
Description
[Technical field]
[0001] The utility model relates to the technical field of foot grinder products, and in particular to a portable foot grinder with reasonable structural design and high practicality and high user experience. [Background Technology]
[0002] Calluses often form on the soles and sides of feet, especially as people get older. Based on the above situation, foot grinders have appeared on the market, which can easily remove calluses and solve problems such as dead skin on the feet. The micro-vibration of the foot grinder itself can also promote blood circulation in the feet, which has certain benefits.
[0003] When using an existing foot grinder, usually the grinding wheel is placed on the foot skin to be polished after the foot grinder is started. The high-speed rotation of the grinding wheel can gradually grind the thick foot skin into thinner skin, thereby completing the grinding of the foot skin. However, after use, the existing foot grinder is often inconvenient to disassemble and clean the grinding wheel, and the operation is complicated, which is not conducive to self-treatment by ordinary consumers.
[0004] For example, the utility model patent with application number CN202321512115.X and patent name "A Foot Grinding Device" specifically discloses a foot grinding device, which relates to the field of foot grinding devices, including a base, a battery fixedly installed on the top of the base, a handle fixedly installed on the top of the base, an upper cover fixedly installed on the top of the base, a circuit board fixedly installed on the top of the base, and a button is arranged on the top of the circuit board, and the circuit board is connected to the battery, and a mounting plate is arranged below the upper cover, and the mounting plate is connected to a motor, one end of the motor is connected to the circuit board, and the output end of the motor is connected to a gear set. The utility model uses a motor and a baffle, and when the foot grinding device is started, the fan can be used to make the ground foot skin be sucked into the inside of the first mounting frame to prevent the foot skin from falling on the ground after being ground. At the same time, the baffle can be set so that the fan can push the baffle when it is started to make the foot skin enter. When the fan stops, the baffle will automatically reset due to the weight of the baffle to prevent the foot skin from leaking out. When cleaning, the foot skin can be poured out by simply opening the cover.
[0005] The related structures of the above-mentioned prior art are not conducive to disassembly and cleaning. Based on this, targeted improvements and enhancements are needed. [Contents of the utility model]
