[0002] Detection solutions are liquids used for chemical analysis, experiments, or tests. They typically contain specific reagents and are used to detect or measure certain components or properties in a sample. Detection solutions are widely used for detecting pesticide residues in agricultural products, heavy metals, or additives. Solution detection is crucial in scientific, industrial, environmental, and medical fields, helping to ensure product quality, environmental safety, and human health.
[0003] In existing detection solutions, the mixed solution adheres to the inner wall of the mixing device during preparation.

Furthermore, the mixing device suffers from insufficient stirring and uneven solution distribution, which also affects the detection results. Therefore, we propose a detection solution mixing device. Utility Model Content
[0004] One of the technical problems this application aims to solve is that, when existing test solutions are mixed, the mixed solution adheres to the inner wall of the mixing device. Incomplete cleaning after use will affect subsequent use and introduce errors in the test results. At the same time, the mixing device has the problem of insufficient stirring when mixing the test solution, and uneven solution distribution will also affect the test results.
[0005] To solve the above-mentioned technical problems, this application provides a device for detecting solution ratio, including a mounting frame. A fixed bevel gear is fixedly connected to the surface of the mounting frame, and a connecting frame is rotatably connected to the middle of the fixed bevel gear. A movable groove is opened on the surface of the connecting frame, and a movable bevel gear is movably connected inside the movable groove. An upper connecting rod and a lower connecting rod extend from both ends of the connecting frame, and a solution mixing tank is fixedly connected between the upper connecting rod and the lower connecting rod.
[0006] In some embodiments, a motor is fixedly connected to the back of the mounting bracket, and the output end of the motor passes through the surface of the mounting bracket and the fixed bevel gear and is fixedly connected to the connecting bracket.
[0007] In some embodiments, a first rotating shaft is fixedly connected to the bottom of the movable bevel gear, a first transmission roller is provided at the bottom of the first rotating shaft, a belt is sleeved on the circumferential side of the first transmission roller, the first rotating shaft passes through the bottom of the connecting frame, the movable bevel gear is engaged with the bottom of the movable groove by the first transmission roller provided at one end of the first rotating shaft, and the fixed bevel gear and the movable bevel gear mesh with each other.
[0008] In some embodiments, a second rotating shaft is provided through the middle of the liquid mixing tank, a fixed shaft is provided at the top of the second rotating shaft, the fixed shaft is movably connected to one end of the upper connecting rod, a second transmission roller is fixedly connected to the bottom of the second rotating shaft, and a stirring blade is fixedly connected to the surface of the second rotating shaft.
[0009] In some embodiments, a liquid guide pipe is fixedly connected to one top end of the liquid preparation tank, and metering cylinders are staggered on both sides of the liquid guide pipe. A liquid outlet is fixedly connected to one bottom end of the liquid preparation tank, and a valve is provided below the liquid guide pipe.
[0010] In some embodiments, the first rotating shaft and the second rotating shaft are parallel to each other, one end of the belt is sleeved on the circumferential side of the first transmission roller, and the other end of the belt is sleeved on the circumferential side of the second transmission roller, wherein the diameter of the first transmission roller is equal to the diameter of the second transmission roller.
[0011] This utility model has at least the following beneficial effects:
[0012] 1. This utility model uses a motor to drive the connecting frame to rotate. Since the movable bevel gear and the fixed bevel gear set below the connecting frame mesh with each other, when the connecting frame rotates, the movable bevel gear will drive the connecting frame to make a circular motion along the center of the fixed bevel gear. This allows the test solution and cleaning agent inside the mixing tank to be fully mixed. The impact force generated by the mixture inside the mixing tank washes away the residue on the inner wall of the mixing tank. The friction between the mixture and the bottle wall also helps to remove the residue, making the cleaning of the mixing tank more thorough.
[0013] 2. This utility model utilizes the meshing action between the fixed bevel gear and the movable bevel gear to enable the belt sleeved on the circumferential side of the bottom first transmission roller to drive the second transmission roller to rotate. When the solution is mixed inside the mixing tank, the solution is stirred, which accelerates the mixing speed and ensures that the solution is evenly distributed inside the mixing tank. This avoids uneven distribution of the prepared solution during use, which could affect the test results. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a device for detecting solution proportioning, including a mounting frame 1. A fixed bevel gear 2 is fixedly connected to the surface of the mounting frame 1. A connecting frame 3 is rotatably connected to the middle of the fixed bevel gear 2. A movable groove 7 is formed on the surface of the connecting frame 3. A movable bevel gear 6 is movably connected inside the movable groove 7. The fixed bevel gear 2 and the movable bevel gear 6 mesh with each other. An upper connecting rod 4 and a lower connecting rod 5 extend from both ends of the connecting frame 3, respectively. A solution mixing tank 8 is fixedly connected between the upper connecting rod 4 and the lower connecting rod 5. The solution mixing tank 8 is used for proportioning solutions. The upper connecting rod 4 and the lower connecting rod 5 are used to fix the solution mixing tank 8. A device is set below the connecting frame 3. The movable bevel gear 6 can rotate around the fixed bevel gear 2 under the meshing action of the fixed bevel gear 2 when the motor 17 drives the connecting frame 3 to rotate, repeatedly inverting the liquid mixing tank 8. When cleaning the solution residue inside the liquid mixing tank 8, it can generate mechanical action, causing the solution to generate impact force inside the liquid mixing tank 8, washing the inner wall of the liquid mixing tank 8. At the same time, the friction generated between the solutions can help peel off the residual solution attached to the inner wall of the liquid mixing tank 8, making the cleaning of the liquid mixing tank 8 more thorough. The motor 17 is fixedly connected to the back of the mounting frame 1, and the output end of the motor 17 passes through the surface of the mounting frame 1 and the fixed bevel gear 2 and is fixedly connected to the connecting frame 3.
[0023] Please see Figure 2-5The bottom of the movable bevel gear 6 is fixedly connected to a first rotating shaft 600. A first transmission roller 601 is located at the bottom of the first rotating shaft 600. A belt 9 is sleeved on the circumferential side of the first transmission roller 601. The first rotating shaft 600 passes through the lower part of the connecting frame 3. The movable bevel gear 6 is engaged with the bottom of the movable groove 7 via the first transmission roller 601 at one end of the first rotating shaft 600. When the movable bevel gear 6 meshes with the fixed bevel gear 2 and rotates, the movable bevel gear 6 simultaneously rotates via the first transmission roller 601 fixedly connected to the first rotating shaft 600. This causes the belt 9 sleeved on the outside to drive the second transmission roller 11 at the other end to rotate. The rotation of the second transmission roller 11 drives... The stirring blades 12, which are fixedly connected to the surface of the second transmission roller 11 inside the mixing tank 8, stir the solution inside the mixing tank 8, accelerate the mixing speed of the solution, and make the solution more uniform. A second rotating shaft 13 is provided through the middle of the mixing tank 8. A fixed shaft 14 is provided at the top of the second rotating shaft 13. The fixed shaft 14 is movably connected to one end of the upper connecting rod 4. The second transmission roller 11 is fixedly connected to the bottom of the second rotating shaft 13. The stirring blades 12 are fixedly connected to the surface of the second rotating shaft 13. While driving the second rotating shaft 13 to rotate, the second transmission roller 11 cooperates with the fixed shaft 14 to fix the mixing tank 8 between the upper connecting rod 4 and the lower connecting rod 5.
[0024] Please see Figure 3-5 A liquid guide pipe 15 is fixedly connected to the top of the mixing tank 8. Metering cylinders 16 are staggered on both sides of the liquid guide pipe 15. An outlet hole 10 is fixedly connected to the bottom of the mixing tank 8. A valve is located below the liquid guide pipe 15. The metering cylinder 16 contains the required quantitative solution for mixing. The valve below the liquid guide pipe 15 is a check valve. When mixing the solution, if the liquid guide pipe 15 is below the mixing tank 8, the solution inside the mixing tank 8 will not enter the liquid guide pipe 15. The pressure of the solution pushes the valve disc against the valve seat, closing the valve and preventing the solution from passing through. If the liquid guide pipe 15 is below the mixing tank 8, the solution inside the metering cylinder 16 will push the valve disc open, allowing the solution to enter. The solution is mixed inside the mixing tank 8. When cleaning the inside of the mixing tank 8, the liquid guide tube 15 is removed and the hole is sealed. The liquid outlet 10 is always sealed during the mixing process and is only opened when liquid needs to be discharged or when cleaning is required. The first rotating shaft 600 and the second rotating shaft 13 are parallel to each other. One end of the belt 9 is sleeved on the circumferential side of the first transmission roller 601, and the other end of the belt 9 is sleeved on the circumferential side of the second transmission roller 11. The diameter of the first transmission roller 601 is equal to the diameter of the second transmission roller 11. The rotation speed of the movable bevel gear 6 is the same as the rotation speed of the second rotating shaft 13, which enables the stirring plate 12 fixedly connected to the surface of the second rotating shaft 13 to stir the internal solution.
[0025] Example 2: Please refer to Figure 6This utility model provides a technical solution: a solution mixing device, including a mounting frame 1, a fixed bevel gear 2 fixedly connected to the surface of the mounting frame 1, a connecting frame 3 rotatably connected to the middle of the fixed bevel gear 2, an upper connecting rod 4 and a lower connecting rod 5 extending from both ends of the connecting frame 3, a mixing tank 8 disposed between the upper connecting rod 4 and the lower connecting rod 5, and a mixing hopper 18 disposed at the top end of the mixing tank 8. The test solution can be directly poured into the mixing hopper 18 for preliminary mixing after the dosage is set. A check valve is disposed at the bottom of the mixing hopper 18. The mixed solution enters the interior of the mixing tank 8. When the dosage of the solution to be mixed is large, the capacity of the mixing hopper 18 can be increased to mix the solution. This device is more adaptable to solution mixing and is easier to operate.
