Problems solved by technology

[0003] However, in the prior art, the existing food additive detection device needs to turn over the cover plate above it after putting it into the cuvette to ensure the light-free environment of the cuvette, but the device is installed in an environment with a lot of dust outside. When the cover plate is turned over during use, the cover plate is easy to press the air below it, so that the air has a certain pressure to flow, and the dust in the air is easy to enter the cuvette with the flowing air as the cover plate is pressed down. within, thereby affecting the accuracy of the detection value of the detection device

Embodiment 1

[0029] Such as Figure 1-3 As shown, the present invention provides a technical solution: a food additive detection device for solid food, comprising a main body mechanism 1, an upper mechanism 2 is arranged above the main body mechanism 1, and a top cover 4 is rotatably connected to the top of the upper mechanism 2. The top of the cover 4 is provided with a through air vent 5, and one side of the air vent 5 is provided with a fixed block 17, one end of the fixed block 17 is fixedly connected with a connecting spring plate 19, and the end of the connecting spring plate 19 away from the fixed block 17 is fixedly connected with a Cover plate 18, the area of ​​cover plate 18 is larger than the area of ​​air vent 5, the top of upper mechanism 2 is fixedly installed with display host 7, the top of display host 7 is fixedly installed with display screen 8, and one side of display host 7 is provided with control board 9. The bottom surface of the control panel 9 and the top of the up...

Embodiment 2

[0032] Such as image 3 and Figure 7 As shown, the two sides of the main mechanism 1 are provided with sliding grooves 16, and the inside of the sliding groove 16 is movably connected with a connecting block 15. One end of the connecting block 15 is fixedly connected with the bottom surface of the upper mechanism 2, and the upper mechanism 2 is connected to the main body through the connecting block 15. Mechanism 1 is movably connected, and a power switch 27 is movably installed inside the slide groove 16, and a side of the power switch 27 is provided with a pressing block 26, and one side of the pressing block 26 is fixedly connected with the inner wall of the upper mechanism 2.

[0033] In this embodiment, through the setting of the power switch 27, the present invention can slide the upper mechanism 2 during use, so that the pressing block 26 moves away from the top of the power switch 27, so that the present invention starts to supply power. The type power switch 27 make...

Embodiment 3

[0035] Such as Figure 1-2As shown, the front of the main body mechanism 1 is provided with a storage tank 10, the inside of the storage tank 10 is rotatably connected with a turning block 11, the bottom surface of the turning block 11 is fixedly connected with a connecting rod 12, and the bottom surface of the connecting rod 12 is fixedly connected with a cleaning sponge 13, The top of the cleaning sponge 13 is provided with a through vent hole 14 .

[0036] In this embodiment, through the setting of the cleaning sponge 13 and the air hole 14, the connecting rod 12 can be passed through the overturning block 11 before the solution reacted with food is injected into the cuvette 6 during use of the present invention. Rotate, then utilize the cleaning sponge 13 to clean the inner wall of the cuvette 6, so that the cuvette 6 can keep the inner wall clean before injecting the solution. When the inner wall moves, the internal air pressure of the cuvette 6 can be kept the same as t...

Abstract

The invention provides a food additive detection device for solid food, and relates to the technical field of detection devices.The food additive detection device comprises a main body mechanism, an upper mechanism is arranged above the main body mechanism, a top cover is rotationally connected to the top of the upper mechanism, a through ventilation opening is formed in the top of the top cover, and a fixing block is arranged on one side of the ventilation opening; and one end of the fixing block is fixedly connected with a connecting elastic plate. According to the invention, through the arrangement of the vent hole and the cover plate, in the use process of the cuvette, when a user places the cuvette into a detection groove and then turns over and covers the top cover, airflow generated by pressing down in the turning process of the top cover can eject the cover plate open from the vent hole and discharge the cover plate to the outside, so that the air pressure generated in the turning process of the top cover is reduced; therefore, when the top cover covers the top of the cuvette, dust in the air cannot be pressed into the cuvette, the color development influence of the dust on a solution in the cuvette is reduced, and the detection accuracy of the device is improved.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a food additive detection device for solid food. Background technique [0002] The food safety rapid detector is mainly used for rapid detection of pesticide residues, formaldehyde, nitrite, sulfur dioxide, hydrogen peroxide, available chlorine, histamine, volatile base nitrogen, diseased meat and benzoyl peroxide in various food and agricultural products. Quantitative determination, where the number indicates the number of effective channels, that is, N items can be detected. The detection of solid food requires a chemical reaction between the food sample and the solution, and then injects the reaction solution into the cuvette of the device. The automatic calculation of color difference comparison can get the exact concentration of the index component in the sample and the result of whether it exceeds the standard. [0003] However, in the prior art, the existing foo...
