Description

Technical Field

[0001] This utility model relates to a silicone lunch box with food freshness monitoring function, belonging to the field of lunch box technology. Background Technology

[0002] Silicone food containers are mostly used in environments where food is carried or stored for a short period of time. Traditional structures have relatively simple functions, so as demand increases, functional development has gradually become apparent, and functions related to food freshness detection have been introduced.

[0003] According to patent application CN204923674U, entitled "A Food Spoilage Detection and Preservation Box," this utility model patent discloses a food spoilage detection and preservation box. "The input terminal of the signal conditioning circuit is connected to a conductivity sensor, a humidity sensor, and a pH sensor. The signal acquisition terminals of the conductivity sensor, humidity sensor, and pH sensor are all exposed on the inner surface of the bottom layer of the preservation box body." This patent application uses multiple sensors for monitoring, which results in a large box structure. This is not only aesthetically pleasing but also increases the overall weight, making it difficult to carry and resulting in mediocre usability. Furthermore, the entire solution does not demonstrate a specific food box structure; it is merely an idealized circuit design. Therefore, a silicone food box with a specific structure, compact overall design, and convenient use, featuring food freshness monitoring, is urgently needed. Utility Model Content

[0004] To address the shortcomings of existing designs, the purpose of this utility model is to provide a silicone lunchbox with food freshness monitoring function. Through structural optimization, the overall structure is compact, space utilization is high, and the usage effect is good.

The lithium battery, odor detector, and circuit board are respectively installed in the power supply mounting slot, the odor detector mounting slot, and the circuit board mounting slot. The LED strip is installed in the LED strip mounting slot. The sealing cover is an integrally molded structure that seals the power supply mounting slot, the odor detector mounting slot, the circuit board mounting slot, and the LED strip mounting slot. The circuit board is wired and connected to the lithium battery, the LED strip, and the odor detector.

[0007] Preferably, the odor detector mounting slot has a through hole that communicates with the inside of the box. The key point of this design is to connect the odor detector with the inside of the box, so as to facilitate real-time detection of food spoilage inside the box.

[0008] Preferably, a wiring groove is provided between the circuit board mounting groove and the light strip mounting groove. The wiring groove is set with the shortest wiring distance to save material costs and make the overall structure compact.

[0009] Preferably, the LED strip mounting slot is located on the top edge of the cover and is a closed ring structure, which can display the light emission color of the LED strip from all directions, so that the food testing situation can be clearly observed.

[0010] Preferably, the sealing cover includes an annular portion that seals the LED strip mounting groove, a strip portion that seals the wiring groove, and a square portion that seals the power supply mounting groove, odor detector mounting groove, and circuit board mounting groove. Furthermore, the sealing cover is a one-piece molded design, resulting in a more compact overall structure and saving space in the accessory box.

[0011] Preferably, the top of the sealing cap is equipped with a waterproof and dustproof plug. This improves the sealing performance and serves to prevent water and dust from entering.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the odor detector can sense the food spoilage in the lunch box, and provide feedback through different colors of LED light strips according to the degree of food spoilage. It can monitor the food condition in the lunch box in real time. Moreover, through optimized structure, the detection component is compact and does not take up storage space, which has great promotional value and application prospects. Attached Figure Description
