TECHNICAL FIELD
[0001] The utility model relates to smell detection technical field, concretely relates to a multifunctional smell detection box. BACKGROUND
[0002] With the continuous progress of society and the significant improvement of people's living standards, consumers' requirements for product health safety and comfort are increasingly strict, especially in terms of sensitivity and pickiness of smell. As one of the most direct and significant sensory feedbacks when consumers experience products, whether there is an odor and the persistence of fragrance has become a key factor in measuring product quality. This trend is not limited to daily necessities, but also extends to the field of high value-added consumer goods such as perfumes and cosmetics, among which consumers have high expectations for the preference and persistence of smell.
[0003] Under this background, the market demand for smell detection technology has grown dramatically, and its importance and urgency are self-evident. However, the existing smell detection instruments generally have limitations in design, mainly focusing on single type of test object, such as smell detection for gaseous environment (such as air quality monitoring), solid sample (such as material volatility test) or liquid product (such as food, beverage aroma analysis). This single detection capability seriously limits its application range in diversified sample testing and cannot meet the growing diversified detection needs in the market.
[0004] Furthermore, the existing detection instruments are not competent in simulating real use environment. Different products may have significant differences in smell release and persistence under different temperature and air flow conditions. However, most of the detection devices on the current market lack the function of adjusting these environmental parameters, resulting in a large deviation between the detection results and the actual use conditions.
[0005] It is particularly noteworthy that although smell durability has become one of the important indicators for evaluating the quality of products such as perfumes and cosmetics, there are few devices on the market that can directly detect this property. This gap not only affects consumers' accurate judgment of product performance, but also restricts the innovation and development of related industries. INVENTION CONTENTS
