Description

Technical Field

[0001] The utility model relates to the field related to food freshness monitoring, and in particular to a portable food freshness monitoring device. Background Art

[0002] Food freshness monitoring is an important part of ensuring food safety and quality. It uses advanced detection technologies, such as sensors to monitor gas composition (such as carbon dioxide, ethylene, etc.), temperature control, humidity regulation, and the use of biological indicators or chemical analysis methods to evaluate the freshness of food in real time or regularly throughout the entire chain from production to consumption. These monitoring methods can effectively prevent food spoilage, ensure the nutritional value and taste of food, and provide consumers with safe and healthy dietary choices.

[0003] Existing food freshness monitoring devices are often large in size and are not convenient to carry to various food storage or sales sites for real-time monitoring, which affects their practicality. In addition, when using existing food freshness monitoring devices, when part of the food is spoiled, the food may move or tilt during the monitoring process due to differences in shape, size or surface characteristics. This instability makes it difficult for the sensor to accurately focus on a specific area that may have been spoiled, and the monitoring results are often significantly affected.

[0004] Therefore, we make improvements on this and propose a portable food freshness monitoring device. Utility Model Content

[0031] In order to solve the technical problems in the background technology, the following portable food freshness monitoring device is provided:

[0032] Combination Figure 1 - Figure 4 As shown, the utility model provides a portable food freshness monitoring device, including a bottom frame 1, a monitoring device body 2 is fixedly installed inside the bottom frame 1, and a control screen 3 is fixedly installed on the front surface of the monitoring device body 2, a placement box 4 is installed on one side of the monitoring device body 2, and a rotating plate 5 is tightly rotatably connected inside the placement box 4, an upper cover 6 is arranged on the upper side of the bottom frame 1, and a connecting mechanism 7 is arranged between the upper cover 6 and the bottom frame 1, and a handle 8 is installed on the upper surface of the upper cover 6, a clamping mechanism 9 is arranged inside the placement box 4, and a gas sensor 10 is installed on the top of the placement box 4; the connecting mechanism 7 includes a mounting block 701, and the mounting block 701 is fixedly installed on the lower surface of the upper cover 6, a mounting groove 702 is opened on the upper surface of the bottom frame 1, and the mounting block 701 is connected to the mounting groove 702 in a snap-fit ​​connection, and a snap-fit ​​structure is formed between the upper cover 6 and the bottom frame 1.

[0033] In this embodiment, when it is necessary to monitor the freshness of food, the food to be tested is placed in the placement box 4, the monitoring device body 2 is controlled by the control screen 3, and the rotating plate 5 is closed to make the placement box 4 in a sealed state. Since spoiled food will produce characteristic gases such as volatile basic nitrogen, organic amines, and sulfides, the gas released by the spoiled food can be captured by the gas sensor 10 on the top of the placement box 4, which is convenient for monitoring the food;

[0034] By placing the monitoring device body 2 into the bottom frame 1 and engaging the mounting block 701 on the surface of the upper cover 6 with the mounting groove 702, it is convenient to combine and connect the bottom frame 1 and the upper cover 6. The handle 8 on the surface of the upper cover 6 makes it easy to carry the device, thereby improving its practicality.

[0035] refer to Figure 1 - Figure 2 On the basis of the above embodiment, in order to be able to fix the bottom frame 1 and the upper cover 6, this embodiment provides the following design:

[0036] As a preferred embodiment, a slot 703 is provided inside the mounting block 701, and a sliding plate 704 is slidably connected inside the slot 703, and a clamping block 705 is fixedly installed on one side surface of the sliding plate 704, and the lower side surface of the clamping block 705 is inclined, a spring 706 is fixedly installed between one side surface of the sliding plate 704 and the inner wall of the slot 703, a clamping slot 707 is provided on one side surface of the mounting slot 702, and the clamping block 705 and the clamping slot 707 are clamped together.

[0037] In this embodiment: since one side surface of the lower side of the block 705 is inclined, when the mounting block 701 is inserted into the mounting groove 702, the block 705 can be squeezed by the inclined surface of the block 705 to make the block 705 slide into the slot 703, and the spring 706 can be squeezed by the sliding plate 704. When the block 705 is aligned with the slot 707, the sliding plate 704 can be supported by the elastic force of the spring 706 itself, so that the block 705 on the surface of the sliding plate 704 is inserted into the slot 707, which facilitates the fixing of the mounting block 701 into the mounting groove 702, and further facilitates the fixed connection between the bottom frame 1 and the upper cover 6.

[0046] In this embodiment, the motor 908 can be started to work, and the motor 908 will drive the driving gear 909 at the output end to rotate, and the driving gear 909 is meshed with the driven gear 906, thereby driving the driven gear 906 and the threaded rod 902 to rotate, so as to facilitate the clamping of food.

[0047] refer to Figure 1 and Figure 3 Based on the above embodiments, in order to make the device easy to use, this embodiment provides the following design:

[0048] As a preferred embodiment, a plurality of fans 11 are fixedly installed at the rear of the storage box 4 .

[0049] In this embodiment: after monitoring the food, the rotating plate 5 is opened, and the fan 11 at the back can be started to blow away the deteriorated gas inside the storage box 4, so as to facilitate the subsequent use of the device.

[0050] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
