Description

Technical Field

[0001] The utility model belongs to the technical field of reaction chambers, and particularly relates to a miniaturized detection reagent reaction chamber. Background Art

[0002] A detection reagent is a solvent that can detect specific bacteria and fungi. During detection, it generally contacts with the solvent to produce a color reaction, and the operator judges by the color. The place where the reaction occurs is called a reaction chamber, also known as a reaction cabin. To facilitate detection, a miniaturized reaction chamber is often used. It is small in size, light in weight, and easy to carry, which is beneficial for detection in outdoor, home or various non-professional detection places. However, most miniaturized reaction chambers have a simple structure, usually a disc-shaped or box-shaped structure, and there are two disadvantages in the use process. One is that it is easy to spill the reagent when putting the reagent into the reaction chamber, and the other is that the sealing performance is not good, and it is easy to be interfered by the external environment and affect the detection result. Therefore, it is necessary to design a new miniaturized reaction chamber to solve this problem. Content of the Utility Model

[0003] The purpose of the utility model is to provide a miniaturized detection reagent reaction chamber to solve the problems of easy spilling of the reagent and poor sealing performance in the use process of the existing miniaturized reaction chamber mentioned in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A miniaturized detection reagent reaction chamber, comprising

[0005] A diversion part, including a rectangular frame and a funnel groove penetratingly opened inside the rectangular frame;

[0006] A reaction part, including a reaction outer shell spliced at the bottom end of the rectangular frame, an installation groove opened inside the reaction outer shell, and a through groove penetratingly connected between the bottom end of the funnel groove and the installation groove;

[0007] A tray slidably installed inside the installation groove, and a top cover rotatably connected to the top end of the rectangular frame.

[0008] Preferably, the front end of the installation groove is open and the rear end is closed, and a pull ring is connected to the front end of the tray.

[0009] Preferably, rubber side pads are symmetrically arranged on both sides of the tray, and the rubber side pads are attached to the inner walls on both sides of the installation groove.

[0010] Preferably, a rubber bottom pad is fixed at the bottom of the reaction outer shell, and suction holes are opened on the bottom surface of the rubber bottom pad.

[0011] Preferably, a sealing component is arranged between the top cover and the rectangular frame, and the sealing component includes a rubber ring fixed on the bottom surface of the top cover and a sealing groove opened on the top surface of the rectangular frame and matching with the rubber ring.

[0012] Preferably, an insertion component is provided between the rectangular frame and the reaction housing. The insertion component includes insertion posts fixed to the bottoms of the four corners of the rectangular frame, insertion holes opened on the top surfaces of the four corners of the reaction housing and inserted with the insertion posts, limiting rings fixed to the surfaces of the insertion posts, and limiting grooves opened on the inner walls of the insertion holes.

[0013] Preferably, the outer surface of the limiting ring is in an arc structure and is clamped with the limiting groove.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] When adding reagents, the top cover can be opened first, and then the reagents can be put into the inside of the diversion part. After being diverted by the diversion part, they enter the inside of the reaction part and come into contact with the test substances on the tray. The personnel can close the top cover to carry out the color reaction. The advantage of this design is that it is not easy to spill the solvent under the action of the diversion part, and it can fully react with the test substances. At the same time, the whole reaction process is in a sealed environment and is not easily interfered by the external environment. BRIEF DESCRIPTION OF THE DRAWINGS
