Technical Field

The invention relates to a matched tableware, in particular to a matched chopstick spoon, a catering utensil and an appliance which are triggered by metal detection to give an electronic prompt.

Background

Because helicobacter pylori is a rather harmful infectious disease transmitted through mouth and mouth, the infection rate of helicobacter pylori in China is as high as 50%, particularly, the abuse of new coronavirus is great, so that the dining culture needs to be improved, and the use of a public chopstick spoon during public dining is advocated. This requires changing the long-standing subconscious habits of the general public, and in order to alert the user to unintended misuse, it is a good elegant solution for the user to feel certain electronic alerts when using the personal chopstick and spoon to get close to the shared eating utensils.

The invention utilizes the basic characteristic of mutual inductance impedance, and is designed in such a way that when the front ends of individual chopsticks or spoons with metal or inductance coils are near shared tableware and utensils, a metal detection device arranged in the tableware or utensil triggers acousto-optic electronic prompt to warn users to change behaviors.

Disclosure of Invention

The invention aims to provide certain corresponding prompt information when personal chopsticks or spoons are close to a shared tableware during public health dining, so that a user can obtain certain warning to correct the subconscious behavior of the user, and the public health level is improved.

In order to achieve the above object, the present invention is a metal detection tableware set, comprising one or more of chopsticks (as shown in fig. 1, item 1) and spoon (as shown in fig. 2, item 4) with metal or inductance coil, and one or more of tableware (as shown in fig. 3, item 5) and utensil (as shown in fig. 3, item 6, item 10, item 14, item 20, item 24, etc.) with metal detection, wherein when the front end of the chopsticks or spoon approaches the tableware or utensil, an electronic prompt is triggered by the metal detection.

The chopsticks and spoon with metal or inductance coils are made of embedded or mixed metal materials, or the whole body of the chopsticks and spoon is made of metal materials, or the chopsticks and spoon contains embedded inductance coils; especially when the diameter of the chopsticks is small, the eddy current of electromagnetic excitation is small, and the inductance coil with the embedded magnetic core can be selected.
