[0003] Traditional food inspection and analysis titration devices are usually based on manual operation. First, the food sample to be detected is prepared in a form suitable for titration, for example, by dilution or extraction.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Refer to Figure 1 - Figure 3 , an embodiment provided by the present utility model: A titration device for food inspection and analysis includes a base 1. A support frame 2 is fixedly connected to the upper surface of the base 1. A titration bottle 3 is slidably connected inside the base 1. A support plate 4 is fixedly connected to the upper end of the support frame 2. A liquid storage tank 5 is fixedly connected inside the support plate 4. An infusion tube 14 is fixedly connected inside the liquid storage tank 5. One end of the infusion tube 14 is fixedly connected to a connecting block 16. A rotating block 17 is rotatably connected inside the connecting block 16. The outer wall of the rotating block 17 is fixedly connected to a second handle 15. The outer wall of the second handle 15 is rotatably connected inside the connecting block 16. The outer wall of the connecting block 16 is fixedly connected to a housing 19. A sealing cover 18 is slidably connected inside the housing 19. A burette 20 is fixedly connected to the outer wall of the housing 19. A clamping assembly is provided inside the base 1.
[0026] Specifically, the food sample to be detected is placed in the titration flask 3, and the titration flask 3 is placed on the base 1. The clamping assembly inside the base 1 is used to fix the titration flask 3 to ensure that it does not move or tilt during titration. The liquid storage tank 5 is fixed on the support plate 4 and contains a standard solution inside. The infusion tube 14 connects the liquid storage tank 5 and the burette 20 and is used to transport the standard solution into the titration flask 3. The operator controls the rotating block 17 by turning the second handle 15, thereby adjusting the opening size of the burette 20 so that the standard solution drips into the sample in the titration flask 3 at a controllable speed. The design of the burette 20 allows for precise control of the volume of the titrant.
[0027] Refer to Figure 1 - Figure 3 The clamping assembly includes a clamping block 22. The outer wall of the clamping block 22 is slidably connected inside the base 1. A second spring 21 is fixedly connected to the outer wall of the clamping block 22. One end of the second spring 21 is fixedly connected inside the base 1, and the outer wall of the clamping block 22 is arranged on the outer wall of the titration flask 3. A trapezoidal block 23 is slidably connected to the outer wall of the clamping block 22, and a cylinder 25 is fixedly connected inside the base 1. The output end of the cylinder 25 is fixedly connected to a fixing plate 24.
[0028] Specifically, the clamping block 22 is located inside the base 1 and is connected to the base 1 through the second spring 21. The trapezoidal block 23 is slidably connected to the outer wall of the clamping block 22, and the output end of the cylinder 25 is connected to the fixing plate 24. In the initial state, the cylinder 25 is in a contracted state, and the clamping block 22 remains in a clamped state under the action of the second spring 21 to fix the titration flask 3. When it is necessary to fix the titration flask 3, the operator activates the cylinder 25 to make it extend and push the fixing plate 24. The movement of the fixing plate 24 is converted into a lateral movement of the clamping block 22 through the trapezoidal block 23, so that the clamping block 22 opens. At this time, the operator can place the titration flask 3 inside the base 1 and make the clamping block 22 clamp it by using the resilience of the second spring 21 by retracting the cylinder 25.
[0029] Refer to Figure 1 - Figure 3 The outer wall of the support plate 4 is fixedly connected with a channel-shaped plate 26. A connecting rod 8 is rotatably connected inside the channel-shaped plate 26. One end of the connecting rod 8 is fixedly connected with a first handle 7. A first connecting plate 9 is fixedly connected to the outer wall of the connecting rod 8. A second connecting plate 10 is rotatably connected to the outer wall of the first connecting plate 9. A third connecting plate 11 is fixedly connected to the outer wall of the second connecting plate 10. One end of the third connecting plate 11 is slidably connected inside the channel-shaped plate 26. A cover plate 6 is fixedly connected to the outer wall of the third connecting plate 11. A first spring 12 is fixedly connected inside the support plate 4. One end of the first spring 12 is fixedly connected with an inclined block 13, and the outer wall of the inclined block 13 is slidably connected to the outer wall of the channel-shaped plate 26.
[0030] Specifically, by rotating the first handle 7, the angle of the connecting rod 8 is adjusted, thereby changing the relative positions of the first connecting plate 9, the second connecting plate 10, and the third connecting plate 11. Since one end of the third connecting plate 11 is slidably connected inside the grooved plate 26, the position of the cover plate 6 will also change accordingly. In this way, the operator can open and close the cover plate 6 as needed.
[0031] Working principle: When a food inspection and analysis titration device is needed, first, the liquid inside the liquid storage tank 5 is introduced into the inside of the connecting block 16 through the liquid delivery pipe 14, and the liquid is introduced into the inside of the housing 19 through the slot hole inside the rotating block 17. By rotating the second handle 15 to drive the rotating block 17 to rotate 90 degrees, at this time, the liquid inside the liquid delivery pipe 14 no longer enters the inside of the housing 19. By rotating the second handle 15 again to drive the rotating block 17 to rotate 90 degrees, the liquid inside the liquid delivery pipe 14 enters the inside of the housing 19. By pulling up the sealing cover 18 with a sealing ring to drive the trapezoidal ring below to move, the hole at the bottom of the housing 19 is opened. By opening the hole, the liquid inside the housing 19 can flow into the inside of the burette 20. By driving the trapezoidal block 23 and the fixed plate 24 to move upward by the air cylinder 25, the clamping block 22 is driven to open to both sides. By moving the air cylinder 25 downward, the clamping block 22 clamps the titration flask 3 through the resilience characteristic of the second spring 21, thereby achieving the effect of clamping and fixing the titration flask 3. By rotating the first handle 7 to drive the first connecting plate 9 to rotate, the second connecting plate 10 drives the third connecting plate 11 to slide along the sliding groove inside the grooved plate 26. When one end of the third connecting plate 11 moves upward to the top, it can act as a rotating shaft so that the other end of the third connecting plate 11 and the second connecting plate 10 can slide along the sliding groove inside the grooved plate 26. By the two ends of the third connecting plate 11 sliding in the sliding groove inside the grooved plate 26, the third connecting plate 11 drives the cover plate 6 to move upward and open, and finally realizes the process of opening and closing the cover plate 6.
[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
