[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] This embodiment provides a detection device for chemical reaction endpoint, which is already in the testing stage. Figure 1-5 Describe together.

[0027] Example

[0028] This embodiment provides a device for detecting the end point of a chemical reaction. Figure 1 , including a burette 1, the burette 1 is detachably connected to a detection disk 2, and the burette 1 is detachably connected to a pressure control component 3 and a titration component 4 from top to bottom. Specifically, Figure 1 and Figure 5 The pressure control assembly 3 includes a threaded side 17 and a rotary cover 18 rotatably connected to the threaded side 17. The threaded side 17 and the rotary cover 18 are connected via a transmission assembly, which is a gear transmission set. In the prior art, the gear transmission set is a combination of a bevel gear set and a sprocket set, that is, a rotary opening and closing structure. By twisting the threaded side 17, the transmission assembly is driven, and then the rotary cover 18 is rotated, thereby slowing the inflow of external gas, thereby gradually increasing the pressure chamber inside the titration assembly 4.

[0029] Next, refer to Figure 2 The detection disk 2 includes a first working surface 21, a second working surface 25, at least one reaction chamber 22, RGB detectors 23, 24 and a driving member 5, wherein the first working surface 21 is provided with a reaction chamber 22, the reaction chamber 22 being electrically connected to the RGB detectors 23, 24, and the reaction chamber 22 including a carrier for holding the detection reagent and a color-transmitting surface arranged parallel to the carrier. The second working surface 25 is detachably connected to the driving member 5, and the driving member 5 is electrically connected to the RGB detectors 23, 24. Specifically, after the reaction in the reaction chamber 22, color will appear, that is, the color will change accordingly. At this time, the RGB detectors 23, 24 will detect the color change and identify the recognized color. This application specifically refers to the detection of red, green and blue, that is, the detection reagent for the titration reaction detection of this application is litmus or phenolphthalein reagent. The RGB detectors 23, 24 will transmit the recognized color to the database of the cloud or back-end processor for subsequent identification and detection operations. The transmission process is a normal data transmission process.

[0030] Further, refer to Figure 3The driving member 5 includes a first electrical driving source 26, a second electrical driving source 27, and a power supply connection 28.

Specifically, the first electrical driving source 26 and the second electrical driving source 27 are both power terminals on the device body, and together with the power supply line 28, they constitute a power transmission system that provides power to the RGB detectors 23 and 24 in the device.

[0031] Furthermore, refer to Figure 4 The titration assembly 4 includes an injection port 11, a pressure-conducting tube 12, a flow-conducting tube 13, an observation tube 14, an accelerating tube 15, and a docking end 16. The end of the injection port 11 is connected to the periphery of the flow-conducting tube 13, the end of the pressure-conducting tube 12 is connected to the end of the flow-conducting tube 13, the inside of the observation tube 14 is connected to the accelerating tube 15, the accelerating tube 15 is connected to the flow-conducting tube 13, and the end of the accelerating tube 15 abuts the bottom end of the docking end 16. Among them, the diameter of the pressure-conducting tube 12 is larger than the diameter of the flow-conducting tube 13, and the diameter of the flow-conducting tube 13 is larger than the diameter of the accelerating tube 15. It should be noted that, according to the principles of fluid mechanics, the flow velocity of the liquid flowing through will increase at this time, thereby achieving the effect of assisting in accelerating the titration reaction.

[0032] Next, the first working surface 21 and the second working surface 25 in this application are arranged in parallel to improve the detection stability of the RGB detectors 23 and 24.

[0033] Finally, in order to ensure the complete operation of the entire device, the power connection 28 is connected to an external three-phase power socket to stably supply power to the RGB detectors 23 and 24 for detection operations.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0035] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution, such as the driving method of the driving member 5, the pressure control method of the pressure control component 3, etc. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
