Description

Technical Field

[0001] This utility model relates to the technical field of vitamin detection, and in particular to a protective shell for a vitamin detection electrode. Background Technology

[0002] Currently, electrochemical methods are one of the mainstream methods for vitamin detection. These methods establish a relationship between the vitamin concentration in the sample and the response current on the electrode by detecting the electrons transferred during redox reactions occurring on the electrode surface. Traditional electrochemical methods for vitamin detection use a three-electrode system with a glassy carbon electrode as the working electrode. This method is costly and requires pre-treatment such as polishing and modification, making the process cumbersome and unsuitable for large-scale market adoption.

[0003] Chinese patent application CN202111123567.4 discloses a screen-printed electrode for detecting vitamin content in plasma. Screen printing technology is a common manufacturing method, widely used in various fields due to its low cost, high efficiency, and good electrochemical performance. This technology integrates the required inks, modifying materials, working electrode, and reference electrode onto the same chip area, eliminating the need for polishing the finished electrode, thus improving efficiency and avoiding errors from manual operation. However, screen-printed electrodes also have drawbacks. The substrates used are mostly soft PVC boards, resulting in thin electrodes that are prone to bending during use, and their dimensions cannot match standard slots. Furthermore, industrial electrodes often only use a thin layer of insulating ink for protection. During use, the liquid being tested is easily splashed, contaminating the test liquid and the testing environment. Additionally, the electrode is easily bent, scratched, and contaminated during storage and transportation, leading to electrode malfunction, affecting test results, or causing short circuits. Therefore, this invention proposes a protective shell for a vitamin detection electrode. Utility Model Content

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0025] Example 1

[0026] Reference Figures 1 to 2 A schematic diagram of the overall structure of a protective shell for a vitamin detection electrode is provided. The protective shell includes an upper shell 100, a lower shell 101 disposed below the upper shell 100, a sample application port 102 on the upper shell 100, a support platform 103 disposed within the lower shell 101, an electrode insertion port 104 disposed on one side of the lower shell 101, and a slider 105 slidably disposed on the upper shell 100. In this embodiment, two support platforms 103 are used, and the slider 105 can slide to either completely block or fully expose the sample application port 102.

[0027] Furthermore, the sample inlet 102 includes a sample inlet 102a formed on the upper shell 100, and an overflow prevention groove 102b that is connected in communication with the sample inlet 102a. In this embodiment, the liquid added to the sample inlet can flow into the overflow prevention groove 102b, one of which is fixedly disposed below the sample inlet 102a.

[0028] Operation process: Slide the slider 105 down from the sample inlet 102a to fully expose the sample inlet 102a, then insert the vitamin detection electrode into the electrode socket 104, add the detection solution into the sample inlet 102a until excess solution flows into the anti-overflow tank 102b, detect the solution through the electrode, clean the solution after detection, slide the slider 105 above the sample inlet 102a, and the electrode sheet can be attached to the sample inlet 102 on the upper shell 100 by the support platform 103.

[0029] Beneficial effects: An overflow preventer 102b is provided next to the sample inlet 102a, allowing operators to accurately add the required amount of test solution. During electrode storage and transportation, the electrode sheet is protected within a protective casing, preventing it from being easily bent or scratched. Sliding the slider 105 to the sample inlet 102a prevents solution contamination during testing. It also prevents splashing of any remaining solution when the electrode is removed from the electrode socket 104.

[0030] Example 2

[0031] Reference Figures 2 to 4This embodiment differs from the first embodiment in that the slider 105 includes a sliding track 105a disposed on the upper shell 100, a sliding cover 105b slidably disposed on the sliding track 105a, and limiting blocks 105c disposed at both ends of the sliding track 105a. In this embodiment, the slider 105 includes two sliding tracks 105a, and the sliding cover 105b slides on these two sliding tracks 105a. The sliding trajectory can cover the sample inlet 102a and the anti-overflow groove 102b. A total of four limiting blocks 105c are provided at the ends of the two sliding tracks 105a.

[0032] Specifically, the sliding track 105a includes a slide body 105a-1 disposed on the upper shell 100, and a snap-fit ​​strip 105a-2 disposed on the outside of the slide body 105a-1. In this embodiment, the slide body 105a-1 is vertically fixed to the upper shell 100, and the snap-fit ​​strip 105a-2 is fixedly disposed on the outside of the slide body 105a-1.

[0033] Furthermore, the sliding cover 105b includes a sliding block 105b-1 slidably disposed on the sliding track 105a, a sliding groove 105b-2 formed below the sliding block 105b-1, and a snap-fit ​​groove 105b-3 formed on one side of the sliding groove 105b-2; the slide body 105a-1 is slidably disposed in the sliding groove 105b-2; and the snap-fit ​​strip 105a-2 is slidably disposed in the snap-fit ​​groove 105b-3.

[0034] The rest of the structure is the same as in Example 1.

[0035] Beneficial effects: The snap-fit ​​strip 105a-2 is set on the outside of the sliding body, which not only realizes the protection function of the sliding part 105, but also makes it easier to clean the electrode protective shell when the solution is accidentally spilled.

[0036] Example 3

[0037] Reference Figures 5 and 6This embodiment differs from the previous embodiments in that the upper shell is connected to the lower shell via a connector 106. The connector 106 includes a threaded opening 106a on the upper shell 100, a connecting through hole 106b on the lower shell 101, a rotating groove 106c at the bottom of the lower shell 101, and mounting screws 106d disposed in the threaded opening 106a and the connecting through hole 106b. In this embodiment, the gap between the upper shell 100 and the lower shell 101 can be adjusted via the connector 106. Six mounting screws 106d are used; four are adjustable mounting screws 106d located near the sample inlet 102a, and the two at the bottom of the shell are ordinary mounting screws 106d. Adjusting the connector 106 allows the vitamin detection electrode to be tightly secured between the sample inlet 102a and the support platform 103. Loosening the connector 106 allows the electrode to be pulled out of the electrode socket 104.

[0038] Specifically, the mounting screw 106d includes a threaded head 106d-1 disposed in the threaded opening 106a and the connecting through hole 106b, a rotating wheel 106d-2 disposed in the rotating groove 106c, and an opening groove 106d-3 disposed on the edge of the rotating wheel 106d-2; the rotating wheel 106d-2 is connected to the end of the threaded head 106d-1. In this embodiment, rotating the mounting screw 106d clockwise tightens the connection between the upper shell 100 and the lower shell 101, and rotating the mounting screw 106d counterclockwise loosens the connection between the upper shell 100 and the lower shell 101.

[0039] The rest of the structure is the same as in Example 2.

[0040] Beneficial effect: Tightening the mounting screws 106d diagonally ensures that the detection electrode is parallel to the sample inlet 102a, preventing the solution from flowing into the protective shell and causing contamination of the shell due to the tilt of the electrode plane when the solution is added.
