Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described below clearly and completely with reference to the accompanying drawings of the embodiments of the present disclosure. It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.

Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure belongs. The use of the word "comprising" or "comprises", and the like, in this disclosure is intended to mean that the elements or items listed before that word, include the elements or items listed after that word, and their equivalents, without excluding other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may also include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.

referring to fig. 1-3, an intelligent weighing spoon comprises a spoon body and a pressure detection device, wherein a lever fulcrum 1 is arranged on a spoon handle of the spoon body, a cantilever beam arm 3 is fixedly bonded at the lever fulcrum 1, and stress sheets 4 are fixedly bonded on two sides of the cantilever beam arm 3.

the pressure detection device comprises a display screen 5 and a pressure detection circuit board 6.

The display screen 5 and the pressure detection circuit board 6 are connected through a wire.

One stress sheet 4 close to the spoon handle is in contact with the spoon handle and forms a lever resistance point 2, and the other stress sheet 4 is connected with the pressure detection circuit board 6 through a lead.

The pressure detection circuit board 6 is provided with a bridge circuit, an AD converter and a processor, the bridge circuit, the AD converter and the processor are connected in sequence through leads, and the processor adopts an STM32 processor.

The inside of ladle body is equipped with the cavity, and the inside of cavity is provided with button cell 7, utilizes the advantage of button cell 7 small, easy installation, is convenient for provide the electric energy for this spoon of weighing and supports.

The object in the spoon produces a pressure to the lever promptly power in the lever, through the lever transmission, also produces a pressure at the other end of lever fulcrum promptly resistance in the lever, according to lever principle: power x power arm is resistance x resistance arm, because resistance arm < power arm, thereby resistance > power, through stress piece 4, pressure measurement circuit board 6 and display screen 5 constitute complete full bridge circuit, article pressure produces the resistance through the lever to cantilever beam arm 3 in the spoon, arouse stress piece 4 to take place elastic deformation, thereby lead to bridge circuit to produce output voltage, voltage signal sends into AD converter and converts digital signal, STM32 treater reading data, carry out the operation analysis, convert voltage signal into corresponding article quality, show on spoon handle display, can read the numerical value of weighing.

Those not described in detail in this specification are within the skill of the art.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
