Description

Technical Field

[0001] The utility model relates to the technical field of food inspection, in particular to a liquid adding device for food analysis and inspection. Background Technique

[0002] Food inspection refers to a discipline that studies and evaluates the quality of food and its changes. It is based on some basic theories and various technologies of physics, chemistry, and biochemistry, and according to the formulated technical standards, such as international and national food hygiene and safety standards, it inspects the quality of food raw materials, auxiliary materials, semi-finished products, finished products, and by-products to ensure that the product quality is qualified. The content of food inspection includes the sensory detection of food, the detection of nutrients, additives, and harmful substances in food, etc.

[0003] When conducting food inspection, generally, one needs to pick up a dropper by hand to suck the required liquid into the dropper, and then inject the liquid inside the dropper into the test tube. This is inconvenient and time-consuming, and accidentally the liquid will touch the hand, thus hurting the skin and causing unnecessary trouble. Based on this, a liquid adding device for food analysis and inspection is proposed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a liquid adding device for food analysis and inspection, effectively solving the deficiencies of the prior art.

[0005] To achieve the above purpose, an embodiment of one aspect of the utility model provides a liquid adding device for food analysis and inspection, including a base. A liquid storage tank and a waste liquid box that can be horizontally pulled out are respectively installed on the top surface of the base. An instrument support frame is installed on the top of the base, and a housing support frame is installed on one side thereof;

[0006] On one side of the top surface of the instrument support frame, a support rod and a diversion box are installed. On the side of the instrument support frame far from the bottom surface of the support rod, a driving motor is installed, and a circular placement rack is installed at its output end. A test tube placement rack that can be disassembled and assembled is installed on the top surface of the circular placement rack;

[0007] A horizontally placed guide rail is installed on the top surface of the support rod, and a micro control pump that moves along its length direction is installed inside it. The output end of the micro control pump bends downward and faces the test tube placement rack. A water pipe is arranged at the input end of the micro control pump, and the water pipe enters the inside of the liquid storage tank;

[0008] A protective housing is installed on the outer wall of the housing support frame.

[0009] Preferably, according to any of the above solutions, a limiting strip is installed on the top surface of the base near the waste liquid box. The limiting strip is respectively placed at three side positions of the waste liquid box. By using this solution, it is convenient to limit the pushing and pulling of the waste liquid box, and the waste liquid box is convenient for receiving the reagent dripping from the output end of the micro control pump, preventing the reagent from entering the top surface of the base.

[0010] Preferably, according to any of the above solutions, one side of the waste liquid box away from the liquid storage tank is flush with the side surface of the protective housing. A handle is installed on the side surface of the waste liquid box away from the liquid storage tank. By using this solution, it is convenient for the user to quickly pull and push the waste liquid box through the handle, improving the operation convenience. At the same time, one side of the waste liquid box is flush with the protective housing, improving the overall appearance aesthetics.

[0011] Preferably, according to any of the above solutions, a rigid tube is installed on the bottom surface of the diversion box. One end of the rigid tube is bent obliquely downward and is directly opposite to the waste liquid box. In this solution, the diversion box is arranged at one side position of the test tube placement rack. After the reagent filling is completed, the electric push rod shortens its action, making the output end of the micro control pump move away from the test tube placement rack and move directly above the diversion box, facilitating the reception of the overflowing reagent.

[0012] Preferably, according to any of the above solutions, an operation handle is installed in the middle of the test tube placement rack. The test tube placement rack is of a circular structure, and grooves are provided at the edges of its top surface. By using this solution, it is convenient to provide a holding position for the user, and then it is convenient for the user to lift the test tube placement rack and multiple food sample test tubes as a whole through the operation handle, facilitating separation from the circular placement rack and facilitating the user's subsequent detection operation on the test tube samples.

[0013] Preferably, according to any of the above solutions, four limiting holes are provided at the edges of the top surface of the circular placement rack. Limiting columns matching the limiting holes are arranged on the bottom surface of the test tube placement rack. By using this solution, it is convenient to limit the placement of the test tube placement rack and at the same time used to transmit torque, enabling the driving motor to drive the circular placement rack and the test tube placement rack to rotate synchronously. To improve the rotation accuracy, a stepping motor can be selected as the driving motor.

By using this solution, it is convenient to provide a power source for the horizontal movement of the micro control pump. At the same time, by the extension or shortening action of the electric push rod, the relative position between the output end of the micro control pump and the food sample test tube is changed, preventing interference with the overall removal of the food sample test tube.
