Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 to 5, the present invention discloses a foot grinder, which includes a substrate 1 and a coating layer 2. Wherein, the base plate 1 is a bamboo product integrated into one piece, the base plate 1 is symmetrical at two ends, and the base plate 1 is a sub-waist arc surface structure. In this embodiment, the arc design of the substrate 1 can be more conformable to the feet of a human body, and when a user applies pressure to the feet through the foot grinder of the present invention during use, the arc-shaped substrate 1 can disperse the pressure to the direction perpendicular to the contact surface of the feet, so that the feet are more uniformly stressed, and local damage to the feet due to improper force application of the user is avoided. When the bamboo product foot grinder is specifically applied, the base plate 1 is integrally formed by the bamboo product, compared with the existing foot grinder made of metal, the base plate 1 has the advantages of high safety and no toxic and harmful substances, and the bamboo product is low in raw material cost, easy to machine and form and further capable of reducing the production cost of enterprises.

Referring to fig. 1 to 5, the substrate 1 of the present invention includes a holding area 11, and a first portion 12 and a second portion 13 connected to two ends of the holding area 11. The first part 12 and the second part 13 are symmetrically designed, and in order to enlarge the use area of the foot grinding device and enhance the universality of the foot grinding device, the holding area 11 is arranged at the middle section of the substrate 1, so that the first part 12 and the second part 13 at two ends are uniformly stressed in the use process of the foot grinding device. In this embodiment, two sides of the holding area 11 along the arc direction are respectively provided with a groove. This recess of district 11 of gripping can make the foot grinder more convenient to use person grips, provides the point of application of force for the user in the use, avoids the smooth injury that leads to of hand simultaneously.

When the outer sidewalls of the first portion 12 and the second portion 13 of the present invention have the first cladding layer 21 and the second cladding layer 22 stacked in sequence, respectively, the thickness of the first cladding layer 21 of the present invention is between 0.1 mm and 1 mm. The thickness of the first coating layer 21 is too thick, which increases the production cost of enterprises, and the thickness of the first coating layer 21 is too thick, which easily causes the second coating layer 22 to be completely wrapped, and the thickness of the first coating layer 21 is too thin, which easily causes the second coating layer 22 to fall off, which is not beneficial to the long-term use of the foot grinder, therefore, the thickness of the first coating layer 21 is most suitable between 0.1 mm and 1 mm. Preferably, the first coating layer 21 is made of epoxy glue with a thickness of 1 mm, the epoxy glue serves as an adhesive for the first coating layer 21 to bond the second coating layer 22 to the first portion 12 and the second portion 13, respectively, and the epoxy glue has strong hardness, water resistance, corrosion resistance and bonding strength, so that the second coating layer 22 can be bonded to the first portion 12 and the second portion 13 more tightly and firmly.

For particular applications, the second cladding layer 22 of the present invention has a thickness of between 0.3 mm and 5 mm. The thickness of the second coating layer 22 is too thick, which increases the production cost of an enterprise, and the thickness of the second coating layer 22 is too thick, which easily causes the second coating layer 22 to fall off, and the thickness of the second coating layer 22 is too thin, which easily causes the grinding performance of the foot grinder to be insufficient, so that the thickness of the second coating layer 22 is most suitable from 0.3 mm to 5 mm. Preferably, the second coating 22 is a brown corundum abrasive with a thickness of 2 mm. The brown corundum abrasive material is also called carborundum, and is used as a second coating layer 22 which is distributed on the outer surface of the first coating layer 21 in a fine and uniform mode, the brown corundum is mainly composed of alumina, the content of the alumina is 95-97%, and the brown corundum additionally contains a small amount of iron, silicon and titanium. The brown corundum has higher hardness and excellent grinding performance, is low in use cost, and reduces the production cost of enterprises while ensuring the grinding effect of the foot grinder.

In the embodiment, a manufacturer calculates the coating amount of the epoxy resin glue according to the surface areas of the outer side walls of the first part 12 and the second part 13, and quantitatively adds the epoxy resin glue with the preset coating amount to the outer side walls of the first part 12 and the second part 13 respectively, and the manufacturer uniformly coats the epoxy resin glue on the first part 12 and the second part 13 to form an epoxy resin glue coating with the preset thickness; and the brown corundum abrasive material with the preset granularity and uniform particles is uniformly covered on the surface of the epoxy resin adhesive coating by a manufacturer, and after the brown corundum abrasive material particles which are not bonded on the surface are shaken out through overturning and vibrating, the epoxy resin adhesive and the brown corundum abrasive material are cured for 6 hours at normal temperature to form a compact and uniform brown corundum abrasive material coating. The thickness of the brown corundum abrasive coating is selected to be 2 mm in order to provide a foot grinder with a proper grinding effect while ensuring stability of the second coating 22, so that a user can use the foot grinder safely and effectively.

In summary, in the embodiment, the bamboo product integrally formed with the foot grinder of the present invention is used as the substrate, and the first coating layer and the second coating layer are sequentially stacked on the substrate. The first coating layer is a macromolecule adhesive, namely epoxy resin glue in the embodiment, and the epoxy resin glue has strong hardness, water resistance, corrosion resistance and bonding strength, so that the second coating layer is not easy to fall off after being used for a long time, and the service life of the foot polisher is prolonged. The second coating is made of an inorganic grinding material, namely brown corundum in the embodiment, the brown corundum has high hardness and excellent grinding performance, the use cost is low, and the production cost of an enterprise is reduced while the grinding effect of the foot grinder is ensured. The grinding material of the second coating layer is granular and can be tightly adhered to the surface of the first coating layer, so that a compact and uniform grinding functional area is formed, the grinding functional area can grind cutin, dead skin and foot cocoons of the foot of a user, and the grinding material has higher hardness, strength and corrosion resistance and is distributed finely and uniformly, so that the foot grinder provided by the utility model can provide a high-efficiency grinding effect and ensure the maximum use safety; the base plate is of a sub-waist-shaped cambered surface structure, so that the foot grinding device disclosed by the utility model can be more attached to each part of the human foot, the grinding functional area is ensured to be more uniformly stressed when being contacted with the human foot, and skin damage caused by stress difference is avoided.
