Description

Technical Field

[0001] This utility model relates to the technical field of water quality testing tools, specifically a reaction cup for water quality testing. Background Technology

[0002] In water quality testing, the reaction cup serves as the container for the chemical reaction between the sample and reagents, and its performance directly affects the accuracy of the test results.

[0003] Traditional reaction cups have the following main technical drawbacks: 1. Temperature sensitivity defect: When existing single-layer structure reaction cups are used outdoors or in environments with large temperature differences, the ambient temperature fluctuations will be directly transmitted to the reaction system, leading to problems such as changes in enzyme activity and abnormal reaction rates, especially affecting the detection accuracy of temperature-sensitive indicators such as COD and BOD. 2. Defects in mixing efficiency: Conventional stirring methods suffer from boundary layer effects. When stirring, a laminar flow zone is formed at the contact surface between the liquid and the cup wall, which reduces the reagent diffusion rate and requires extending the stirring time.

[0004] Therefore, we propose a reaction cup for water quality testing. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a reaction cup for water quality testing, which solves the problem of data deviation caused by environmental temperature fluctuations in traditional reaction cups, and improves the stirring effect, thus effectively solving the problems in the background technology.

[0006] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: a reaction cup for water quality testing, comprising an outer cup body, an inner cup body inserted into the inner cup body, an installation cavity provided inside the outer cup body shell, the installation cavity being filled with heat insulation material, an external threaded ring formed on the upper outer wall of the inner cup body, a protrusion fixedly installed on the inner wall of the inner cup body, a cup lid provided on the upper part of the inner cup body, a regular hexagonal limiting groove formed in the middle of the lower outer surface of the inner cup body, a regular hexagonal limiting block fixedly installed at the middle of the bottom of the inner cavity of the outer cup body, a hydrophobic coating provided on the inner wall of the inner cup body, and reinforcing rings fixedly installed at equal intervals in the installation cavity of the outer cup body.

[0007] Preferably, the heat insulation material is aerogel.

[0008] Preferably, the cup lid and the external threaded ring are connected by a thread.

[0009] Preferably, after the lower part of the inner cup is inserted into the interior of the outer cup, the position of the external threaded ring on the upper part of the inner cup is located on the upper part of the outer cup, and the cup cover is threadedly connected to the external threaded ring.

[0011] Preferably, the thickness of the hydrophobic coating is 0.5~20μm.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a reaction cup for water quality testing, which has the following advantages: 1. This reaction cup for water quality testing has a heat insulation function through the nested design of the outer cup and the inner cup, which avoids abnormal reaction rate caused by environmental temperature difference during the testing process. It is especially suitable for water quality testing in outdoor or low-temperature environments.

[0013] 2. This reaction cup for water quality testing, through the protrusions, disrupts the laminar flow of the liquid during stirring, enhances the turbulent effect, and allows the reagent to mix with the water sample quickly and thoroughly, thus shortening the reaction time.

[0014] 3. This reaction cup for water quality testing, through the setting of regular hexagonal limiting groove and regular hexagonal limiting block, facilitates the improvement of the stability of the inner cup body inside the outer cup body, and avoids the inner cup body from rotating inside the outer cup body when the liquid is stirred inside the inner cup body by the stirring shaft.
