[0038] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0039] Referring to Figures 1-7 , the controllable fluid chemical reagent automatic distribution device based on ESP32 includes experimental support 1, and the experimental support 1 is composed of test tube base 11 and limiting platform 13, and the specific reference specification appendixFigure 1 With the attached Figure 3 The test tube base 11 and the limiting platform 13 are fixedly connected with two reinforcing support rods 12, the test tube base 11 and the limiting platform 13 can be disassembled and connected through the reinforcing support rods 12, the experimental support 1 with a box structure can vertically place and support the reaction test tube 21 and the feeding test tube 22, and the test tube base 11 and the limiting platform 13 are provided with a limiting machine set 14, and further, the limiting machine set 14 includes a first limiting groove 141 provided in the middle position of the test tube base 11 and a first limiting hole 142 provided in the middle position of the limiting platform 13, and the first limiting groove 141 and the first limiting hole 142 are used for vertically fixing the reaction test tube 21, the limiting machine set 14 further includes a second limiting groove 143 provided in the both sides of the test tube base 11 and a second limiting hole 144 provided in the both sides of the limiting platform 13, and the second limiting groove 143 and the second limiting hole 144 are used for vertically fixing the feeding test tube 22, it should be noted that one first limiting hole 142 and one first limiting groove 141 corresponding to each other form a group, the number of groups is one, which is used for fixing and placing one reaction test tube 21, one second limiting hole 144 and one second limiting groove 143 corresponding to each other form a group, the number of groups is four, which is used for fixing and placing four feeding test tubes 22, and the reagent management mechanism 2 and the adjusting mechanism 3 make the four feeding test tubes 22 transport raw materials into the reaction test tube 21.

[0040] The experimental support 1 places the reagent management mechanism 2 composed of the reaction test tube 21 and the feeding test tube 22 through the test tube base 11 and the limiting platform 13, and the specific reference is made to the attached Figure 1 With the attached Figure 4 The reagent management mechanism 2 includes a feeding pipeline 23 fixedly connected to the feeding test tube 22 and a discharging pipeline 24 fixedly connected to the reaction test tube 21, it should be noted that each feeding test tube 22 forms a single-phase connection between the reaction test tube 21 through the feeding pipeline 23, the water pump 38 and the discharging pipeline 24, so as to avoid mutual pollution between different feeding test tubes 22, and each water pump 38 can extract according to the preset volume according to the control of the single-chip microcomputer.

[0041] The experimental support 1 is further provided with an adjusting mechanism 3 for automatically distributing the reagent in the feeding test tube 22 into the reaction test tube 21, and the specific reference is made to the attached Figure 1 With the attached Figure 5The dispensing mechanism 3 includes a PLC controller 31 and a charging module 32 fixedly arranged in the test tube base 11. It should be noted that the PLC controller 31 adopts ESP32, which not only has various input and output interfaces and can process various sensor data, but also can accurately extract the dose of reagent by controlling the water pump 38. Specifically, it receives and processes data from the temperature and humidity sensor 34 and the photosensitive sensor 35 to monitor and adjust the experimental environment. The ESP32 is also responsible for receiving instructions input by the user through the button 37 and controlling the water pump 38 to accurately extract the reagent according to these inputs. The ESP32 also controls the display of the display screen 36 to present environmental data and operation interfaces to the user. The charging module 32 is electrically connected with the lithium battery 33 electrically connected with the PLC controller 31. The power supply is realized by the charging module 32 and the lithium battery 33, which ensures the stable operation and convenience of use of the dispensing mechanism 3. The temperature and humidity sensor 34 and the photosensitive sensor 35 are fixedly installed in the limiting platform 13 and electrically connected with the PLC controller 31. The display screen 36 and the button 37 are fixedly installed on the limiting platform 13 and electrically connected with the PLC controller 31. The water pump 38 is fixedly installed on the limiting platform 13 and electrically connected with the PLC controller 31 and communicates with the feeding pipeline 23 and the discharging pipeline 24.

[0042] It is worth noting that in order to accurately control the operation of the water pump 38 as needed, precise extraction of fluid is achieved. The'motorSet' function receives two parameters:'motor' specifies the motor to be controlled, and'spe' is used to set the speed of the motor. If the value of'spe' is positive, the motor will rotate in one direction; if it is negative, it will rotate in the opposite direction. The function uses the 'ledcWrite' function to set the PWM signal of a specific channel, thereby controlling the speed of the motor.

[0043] From the device initialization, to ensure that all functions are in a ready state, the PLC controller 31 reads the data of the temperature and humidity sensor 34 to obtain the temperature and humidity information of the current environment, and then reads the data of the photosensitive sensor 35 to obtain the light intensity information. The above information is displayed on the display screen 36.

[0044] The PLC controller 31 detects the state of the button 37. If no button 37 operation is detected, the PLC controller 31 will continue to monitor the photosensitive data. Once the button 37 is detected to be pressed, the PLC controller 31 will control the water pump 38 to extract the reagent raw material in the feeding test tube 22 according to the preset value input by the user.

[0045] After the extraction is completed, it returns to the step of monitoring the photosensitive data again to maintain a continuous monitoring and operation cycle.

[0046] The test tube base 11 is fixedly provided with a charging port 321 electrically connected with the charging module 32.

[0047] According to the number of feeding test tubes 22, a corresponding number of water pumps 38 or air pumps can be equipped to extract different volumes of reaction reagents and gases, which are accurately controlled by the single-chip microcomputer to ensure that the amount of reaction reagents in the reaction test tube 21 meets the preset value.

[0048] By setting the temperature and humidity sensor 34, the light sensor 35, the temperature and humidity of the environment can be detected in real time, and the light intensity can be recorded and displayed in real time, which is convenient for monitoring and analysis. The temperature and humidity sensor 34 monitors and collects the temperature and humidity data in the environment in real time, and the light sensor 35 monitors the light intensity in the environment in real time. By feeding these data back to the ESP32, the PLC controller 31 can adjust or maintain constant environmental conditions according to the experimental needs, ensuring that the chemical reaction is carried out at an appropriate temperature and humidity. By accurately controlling the light conditions in the experimental environment, the accuracy and repeatability of the experimental results can be ensured.

[0049] By configuring the keys 37 and the display screen 36, the display screen 36 is preferably a touch screen, which can select the feeding test tube 22 and set the extraction amount of the reaction reagent through the menu on the display screen 36 or the keys 37, which is convenient for user operation and monitoring. The 'btnControl' function reads the state of the three keys 37 through 'digitalRead': the increase key, the decrease key and the switch key. If the increase key is pressed and the value of 'num' is less than 10, the value will increase, and similarly, if the decrease key is pressed and 'num' is greater than 0, the value will decrease. After each change in the state of the key 37, there is a short delay to prevent jitter.

[0050] The test tube base 11 is provided with a limiting mechanism 4 for fixing the bottom end of the reaction test tube 21 and the supply test tube 22. It should be noted that the number of limiting mechanisms 4 is determined according to the number of reaction test tubes 21 and supply test tubes 22. The limiting mechanism 4 includes a concave groove 41 provided in the test tube base 11 and communicating with the first limiting groove 141 and the second limiting groove 143. The concave groove 41 is fixedly provided with a driving cylinder 42. The output end of the driving cylinder 42 is fixedly connected with a load carrier 43 which extends into the first limiting groove 141 and the second limiting groove 143 and is used to support the reaction test tube 21 and the supply test tube 22. The top end of the concave groove 41 is provided with a light sensor 44 for monitoring the reaction test tube 21 and the supply test tube 22 and connecting the driving cylinder 42. It should be noted that the light sensor 44 can be electrically connected with the PLC controller 31 to facilitate unified deployment of the driving cylinder 42. The concave groove 41 is slidably provided with a lifting plate 45 which is fixedly pulled by the load carrier 43. The concave groove 41 is welded with a return spring 46. The return spring 46 is welded with a limiting clamp 47 which is movably pulled by the lifting plate 45 and is used to abut and clamp the reaction test tube 21 and the supply test tube 22. It should be noted that the return spring 46 is a tension spring. Under the tension of the return spring 46, the limiting clamp 47 in the initial state is retracted in the concave groove 41. When the light sensor 44 senses that the reaction test tube 21 and the supply test tube 22 extend into the first limiting groove 141 and the second limiting groove 143, the driving cylinder 42 is controlled to be opened, so that the load carrier 43 supports the reaction test tube 21 and the supply test tube 22 to vertically move downward, and at the same time drives the symmetrically arranged limiting clamps 46 to move towards each other, so as to clamp and limit the reaction test tube 21 and the supply test tube 22 in the first limiting groove 141 and the second limiting groove 143, thereby ensuring the stability of the reaction test tube 21 and the supply test tube 22. The end of the limiting clamp 47 towards the first limiting groove 141 and the second limiting groove 143 adopts an arc plate structure to closely fit the reaction test tube 21 and the supply test tube 22, thereby ensuring the firmness of abutting and clamping, and a rubber pad can be used to enhance the adsorptivity and protectivity.

[0051] A wedge-shaped through hole 451 is formed in the lifting plate 45. An inclined surface 471 is formed at one end of the limiting clamp 47 and abuts against the wedge-shaped through hole 451. During the process of vertically moving downward of the lifting plate 45 driven by the load carrier 43, the inclined surface 471 is pressed through the wedge-shaped through hole 451. During the process of pressing the return spring 46, the limiting clamp 47 extends into the first limiting groove 141 or the second limiting groove 143, so as to clamp and limit the reaction test tube 21 or the supply test tube 22 located in the first limiting groove 141 or the second limiting groove 143.

[0052] It should be noted that the PLC controller 31, the charging module 32, the lithium battery 33, the temperature and humidity sensor 34, the light sensor 35, the display screen 36, the key 37 and the water pump 38 adopt specific model specifications, which need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the art, so it is not described in detail.

[0053] The utility model can be described by the following operation mode to explain its function principle:

[0054] The reaction test tube 21 and the feeding test tube 22 are respectively placed vertically in the first limiting groove 141 and the second limiting groove 143, the driving cylinder 42 controls the vertical downward movement of the load carrier 43, and the limiting clamp 47 extends into the concave groove 41, so as to clamp and limit the reaction test tube 21 and the feeding test tube 22;

[0055] The temperature and humidity sensor 34 and the light sensor 35 obtain the conditions of the environment where the experiment is located, the PLC controller 31 judges according to the condition information, controls the water pump 38 to run, extracts the raw materials in the corresponding feeding test tube 22 and transports them into the reaction test tube 21, and then observes after the reaction.

[0056] The above is only a preferred embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
