Smell detection cover and container

Abstract

The invention discloses a smell detection cover for monitoring a food smell in real time and a container containing the smell detection cover. The smell detection cover fits to the container containing a sample to be detected. The smell detection cover comprises a cover member, a smell detection part which is used for detecting the current smell of an object to be detected in real time and at least producing a corresponding current smell value in real time, a smell value processing part which produces a current smell change value according to the smell initial value and the current smell value, a display part which displays the current smell value and the current smell change value, a communication part and a power supply part. The smell detection part comprises at least one first gas sensor for producing a first response signal according to the detected smell of an object to be detected, at least one second gas sensor for producing a second response signal according to the detected smell of the object to be detected, and a smell data generation chip for producing the current smell value according to the first and second response signals.

Description

technical field [0001] The invention specifically relates to an odor detection cap and a container comprising the odor detection cap. Background technique [0002] With the gradual improvement of the current living standard, people's requirements for the quality of life are also increasing. In order to improve the quality of life, people now not only pay attention to the quality of the food itself, but also pay attention to the time when the food goes bad. At present, glass and plastic cups, bowls, jars, barrels and other containers are commonly used in household life to store food and drinks independently. However, since the containers are usually sealed and stored independently, it is difficult for users to obtain the information immediately when the food in the container changes. . [0003] In addition, consumers often use life experience to identify whether food is spoiled, but the different degrees of spoilage of different foods do not show the same judgment character...

AI Technical Summary

Problems solved by technology

At present, glass and plastic cups, bowls, jars, barrels and other containers are commonly used in household life to store food and drinks independently. However, since the containers are usually sealed and stored independently, it is difficult for users to obtain the information immediately when the food in the container changes.

[0003] In addition, eaters often use life experience to identify whether food is spoiled, but the different degrees of spoilage of different foods do not show the same judgment characteristics, and when the actual situation is different, life experience often cannot be used as a basis for judgment

At this time, the eater may eat the spoiled food by mistake to make himself sick, or throw away the unspoiled food to cause waste, or miss the best time to drink / eat the food

[0004] At present, most of the products in the same period on the market use signal acquisition terminals (such as humidity sensors, pH sensors, etc.) to directly collect food-related data, which not only easily causes pollution to the signal acquisition terminal, but also causes cross-contamination of the detected objects. In addition, most of them cannot provide Provide users with intuitive and continuous parameter data of the object to be detected
