Description

A fat measurement pound

Technical field

The present invention relates to an apparatus for measuring the amount of fat in an animal's body, and in particular to a human body fat measuring pound.

Background technique

At present, the fat measuring pounds on the market generally use glass pound noodles, glass is an insulator, and metal wires or metal strips are provided on both sides of the pound noodles as electrodes. When measuring fat, both feet stand on either side, DC or AC. Through the body, measure the amount of body fat. This structure requires an ultra-high vacuum adhesive to make the metal wire or metal strip adhere to the glass pound surface. The adhesive cost is high and the bonding process is time-consuming and laborious. Because the molecules of metal materials are not active under normal conditions, it is often difficult to make metal wires or metal strips adhere to the glass surface. If the metal molecules are activated by heating or other methods for bonding, it is particularly time-consuming and labor-intensive. Resources; even if the bonding is proper, at high temperatures or during the transportation of the product, or after long-term or frequent use, the metal wires or metal bars often fall off, causing waste and inconvenience. Because metal wires or metal strips must be placed on the surface of the fat measuring glass, the appearance of the product is limited and affected. In addition, some metal materials have adverse effects on human health, and direct contact between the feet and metal materials poses a certain danger. If the perimeter of the metal wire or metal strip is not handled properly and is too sharp, it can also cut people and cause danger.

Summary of the Invention

The purpose of the present invention is to solve the technical problem that a metal wire or a metal strip is connected on a pound surface as an electrode, the bonding process is time-consuming and laborious, the cost is high, and the metal material makes the appearance of the product not beautiful and safe enough, and provides an electrode. Easy bonding, easy appearance, safe fat measurement.

In order to achieve the above object, the present invention adopts the following technical solution: A fat measurement scale includes a scale foot component, a scale surface, a display component, and an electronic component. The scale surface is provided with two isolated conductive coatings. Two conductive coatings are electrically connected to the electronic component, the circuit is connected, and the two conductive bodies form electrodes; in the case of direct current, the two conductive bodies form positive and negative electrodes; in the case of alternating current, the two conductive pieces The body does not distinguish between positive and negative electrodes.

The electrical conductor is a metal oxide coating.

The conductive body is an indium tin oxide coating.

The present invention adopts the above technical solution, which has the following advantages: Since the present invention does not need to use an ultra-high vacuum adhesive, but uses a metal oxide to make a coating as a conductor, which can save production processes and Cost, save time and effort. According to the forming characteristics of the metal oxide, the appearance design change and aesthetics of the product can be greatly increased. The metal oxide coating has a large area, which is easy to fit with different shapes and sizes of the soles, and is more convenient to use. Moreover, the metal oxide will not fall off once it forms a coating on the glass layer, and the material has the advantages of light weight, waterproof, high temperature resistance and harmless to the human body.

detailed description

As shown in Figures 1 to 4, one embodiment of the present invention. The present invention includes a foot scale component 1, a scale surface 2, a display 'component 3, and an electronic component 4. The scale surface 2 is circular and made of glass material, and the shape can also be other geometric shapes such as oval, square, etc. Wait. Two isolated electrical conductors 21 are provided on the scale surface 2, and the front ends of the two electrical conductors 21 are respectively electrically connected to the electronic component 4. The circuit is connected, and the two electrical conductors 21 form electrodes. The two conductors 21 are coatings made of metal oxide, especially indium tin oxide. The scale foot 2 is provided with the scale foot component 1, and the scale foot component 1 passes through the wires 11 and The electronic component 4 is electrically connected, and the electronic component 4 is electrically connected to the display component 3. A button 5 is provided on the layout of the display assembly 3, and the age, height, and gender of the person to be tested can be input through the button 5, respectively. When two feet stand on the pound surface 2, direct current or alternating current passes through the body. The signal is transmitted to the electronic component 4, and the weight of the human body is also measured through the pound foot component 1 and transmitted to the electronic component 4. The electronic component 4 calculates and processes all data together to measure the body fat Displaying the fat mass through the display assembly 3.
