The device is suitable for accurately controlling different types of diffuse media, providing a stable and repeatable experimental environment for research on radiation transfer, optical imaging experiments, etc. Background Art

[0002] In experiments related to radiation transfer and optical imaging, diffuse media (such as smoke, mist, and dust) are often used to simulate the scattering and transmission characteristics of light in complex environments. Existing diffuse media generation devices use a single type of diffuse medium and fail to precisely control the amount of generated diffuse medium. This makes it difficult to achieve consistent experimental conditions, leading to unstable experimental results. Furthermore, the fact that media such as smoke and mist are prone to dispersion during their generation and transmission further increases experimental uncertainty.

[0003] Currently, there is no control device that can accurately control the amount of diffuse medium. Therefore, in order to meet the needs of radiation transfer and optical experiments, it is necessary to design a diffuse medium generation control device to solve this problem. Summary of the Invention

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figure 1 As shown, this embodiment 1 provides a dispersion medium generation control device, comprising: a storage chamber 16, a generator chamber 1, and a buffer chamber 13 connected in sequence. The generator chamber 1 is used to set a dispersion medium generator. One side of the generator chamber 1 is connected to the buffer chamber 13 via a first connecting pipe 7, and the other side is connected to the storage chamber 16 via a second connecting pipe 15.

[0035] The buffer chamber 13 is used to temporarily store the dispersion medium during its generation process. A buffer chamber piston 14 is located at the top of the buffer chamber 13. This piston 14 is used to adjust the pressure in the generator chamber 1 during the generation process and, after the generation process is complete, to press the dispersion medium into a storage chamber 16. The storage chamber 16 is used to store the generated dispersion medium. The buffer chamber piston 14 on the buffer chamber 13 can automatically adjust its position based on changes in internal pressure, ensuring pressure balance between the generator chamber 1 and the buffer chamber 13, and preventing uneven generation or leakage of the medium due to pressure fluctuations.

[0036] Specifically, the dispersed medium generation control device described in this embodiment further includes a detection chamber 19 for conducting detection experiments. The detection chamber 19 is connected to the storage chamber 16 via the third connecting pipe 18. The detection chamber 19 is provided with a concentration detection and calibration module 22 and an air outlet pipe 20. The concentration detection and calibration module 22 is used to detect the concentration of the medium. The concentration detection and calibration module 22 integrates a highly sensitive sensor and a data processing unit, enabling rapid and accurate measurement of the concentration of the dispersed medium entering the detection chamber. A storage chamber piston 17 is provided at the top of the storage chamber 16, which is used to press the dispersed medium in the storage chamber into the detection chamber 19.

[0037] Specifically, in this embodiment, the detection chamber 19 is also provided with a window 21 for allowing light to pass through. Window 21 is made of high-transmittance borosilicate glass to ensure the accuracy and precision of optical detection. Window 21 is a detachable structure, attached to the wall of the detection chamber 19 via a specially designed sealing ring and snap-fit ​​mechanism. This ensures a tight seal while facilitating regular cleaning of the diffused medium adhering to the glass surface. The sealing ring is made of high-temperature-resistant silicone rubber to ensure a good seal even at high temperatures, preventing leakage of the diffused medium and ingress of external air.

[0038] Specifically, in this embodiment, the storage chamber 16 and the detection chamber 19 are made of quartz glass, and have a size of 100 mm×100 mm×150 mm.

[0039] Furthermore, in this embodiment, control valves are provided on the first connecting pipe 7 , the second connecting pipe 15 and the third connecting pipe 18 .

[0040] Furthermore, the dispersion medium generation control device in this embodiment further includes a drive motor provided on the storage bin 16 , and the drive motor is used to control the movement distance of the storage bin piston 17 .

[0041] Specifically, in this embodiment, a bin cover 4 is provided on the top of the generating bin 1, and an air inlet pipe 3 is provided on the bin cover 4. The air inlet pipe 3 is used to connect to the gas source to provide oxygen to the dispersion medium generation process; the dispersion medium generator set in the generating bin 1 is a smoke generator, and the smoke generator includes: a storage table 6 and an electronic igniter 5. The storage table 6 is used to place the smoke generating substance, and the electronic igniter 5 is used to ignite the smoke generating substance to generate the dispersion medium.

[0042] Specifically, an electronic igniter 5 is mounted at the bottom of the generator chamber 1 and can be controlled externally for ignition. A storage platform 6, made primarily of high-quality, high-temperature-resistant silicon carbide, is used to house the smoke-generating material. An oxygen connection port 2 is provided on the air inlet pipe 3, which passes through the chamber cover and into the generator chamber 1, providing oxygen during the combustion of the smoke-generating material. The generator chamber 1 is connected to a buffer chamber 13 via a first connecting pipe 7. A freely sliding buffer chamber piston 14 is located at the top of the buffer chamber 13.

[0043] Specifically, in this embodiment, the generating chamber 1 and the buffer chamber 13 are made of quartz glass, and have a size of 150 mm×150 mm×200 mm.

[0044] Furthermore, in this embodiment, the first connecting tube 7, the second connecting tube 15, the third connecting tube 18, the air inlet pipe 3, and the air outlet pipe 20 are all made of PTFE material, which has excellent chemical resistance, high temperature resistance, and a low friction coefficient, and can maintain stability and durability in high-temperature and corrosive environments. At the same time, the internal surface of the connecting tube is smooth, which can effectively reduce the resistance of the fluid during transmission and improve the efficiency of fluid transmission. The design of the connecting tube takes into account the dispersion of the dispersed medium and uses high-quality sealing rings and fasteners to ensure the airtightness of the connection and reduce the possibility of leakage during the experiment.

[0045] In this embodiment, the generating chamber 1 is the core part of the dispersed medium generation, which can withstand high temperatures and provide good optical transmittance. The generating chamber 1 adopts a modular design and can be replaced according to the generation requirements of different types of dispersed media. The main function of the buffer chamber 13 is to balance the internal pressure changes during the generation process and ensure that the dispersed medium can be smoothly input into the storage chamber. The storage chamber 16 is used to temporarily store the generated dispersed medium. The output of the dispersed medium input into the detection chamber 19 can be controlled by the storage chamber piston 17, thereby achieving precise control of the dispersed medium supply. The chamber wall of the detection chamber 19 is composed of a detachable medium, which is used for the transmission of light in experiments such as radiation transfer and optical imaging. The detection chamber 19 is equipped with a high-precision concentration detection and calibration module 22, which can collect the concentration data of the dispersed medium in the detection chamber to ensure that it meets the requirements of the optical experiment. The chamber bodies of the generating chamber 1, the buffer chamber 13, and the storage chamber 16 are all made of high-transmittance quartz glass, which is convenient for observing the condition of the dispersed medium in the chamber.

[0046] Example 2

[0047] The embodiment of the present invention provides a diffusion medium generation control device, which is the same as the first embodiment in that it includes: a detection chamber 19, a storage chamber 16, a generation chamber 1 and a buffer chamber 13 connected in sequence.

[0048] Different from the first embodiment, in this embodiment, the dispersion medium to be generated in the generating chamber 1 is water mist, and the dispersion medium generator provided in the generating chamber is a water mist generator. Figure 2 As shown, in this embodiment, the water mist generator specifically includes: a water container 10 and an ultrasonic oscillator 11; the ultrasonic oscillator 11 is used to vibrate the water in the water container 10, and through high-frequency resonance, generate fine and uniform particles to produce water mist.

[0049] Specifically, in this embodiment, the generator chamber 1 is made of quartz glass and measures 150 mm x 150 mm x 200 mm. A water container 10 is located at the bottom of the chamber 1 and is marked with scale to control the amount of water added. This ensures a consistent amount of water mist is generated each time. Furthermore, to withstand the stress and pressure changes generated during ultrasonic oscillation, the water container 10 is primarily made of high-strength borosilicate glass. An ultrasonic oscillator 11 for producing water mist is installed within the water container 10.

[0050] Specifically, in this embodiment, each chamber is provided with a connecting port 12, which is designed with threads. The first connecting pipe, the second connecting pipe, and the third connecting pipe between each chamber can be firmly connected to the connecting port 12 by screwing, ensuring the sealed transmission of the dispersed medium.

[0051] Example 3

[0052] A third embodiment of the present invention provides a method for controlling the generation of a dispersion medium, which is implemented based on the device for controlling the generation of a dispersion medium described in the first or second embodiment, and includes the following steps:

[0053] Step 1: Open the cover of the generating chamber 1 , set the dispersed medium generator in the generating chamber 1 , close the cover, open the first connecting pipe 7 , and close the second connecting pipe 15 .

[0054] When the diffusion medium to be generated is smoke, the step 1 also includes the step of connecting the oxygen supply equipment to the air inlet pipe 3 and inputting oxygen into the generating chamber 1; during operation, first open the chamber cover 4 on the top of the generating chamber 1, put in the smoke generator, and then put a fixed weight of smoke generating material on the storage table 6, close the generating chamber cover 4, connect the oxygen supply equipment to the oxygen supply connection port 2, close the second connecting pipe 15, open the first connecting pipe 7, externally control the electronic igniter 5 to ignite the smoke generating material, open the valve of the air inlet pipe 3, and strictly control the amount of oxygen input. By controlling the amount of oxygen input, it can be ensured that the total amount of smoke generated after the smoke generating material is fully burned each time is constant.

[0055] When the dispersed medium to be generated is water mist, the chamber cover 4 on top of the generating chamber 1 is opened, the water mist generator is placed in, water is poured into the water container 10, and then the water container 10 and the ultrasonic oscillator 11 are placed in the generating chamber. The ultrasonic oscillator 11 is activated under external control. Controlling the amount of water injected each time to be equal ensures that the total amount of water mist generated is constant.

[0056] Step 2: Turn on the dispersion medium generator to start generating dispersion medium. During the dispersion medium generation process, the buffer chamber piston 14 is allowed to freely expand and contract under the action of atmospheric pressure to keep the air pressure in the generating chamber 1 constant.

[0057] During the combustion of the smoke generating material, the dispersed medium in the generating chamber 1 enters the buffer chamber 13 through the first connecting pipe 7, and the buffer chamber piston 14 automatically adjusts according to the pressure change to stabilize the pressure between the buffer chamber 13 and the generating chamber 1.

[0058] During the water mist generation process, the dispersed medium in the water mist generating chamber 1 enters the buffer chamber 13 through the connecting pipe 7, and the buffer chamber piston 14 will automatically adjust according to the pressure change to stabilize the pressure between the buffer chamber 13 and the generating chamber 1.

[0059] Step 3: After the dispersion medium generation process is completed, the second connecting pipe 15 is opened, and the buffer bin piston 14 is controlled to move downward to press the dispersion medium in the buffer bin 13 into the storage bin 16 .

[0060] In this embodiment, after the dispersion medium is generated in the generating chamber 1 and the buffer chamber 13, the storage chamber piston 17 is adjusted to the bottom, the second connecting pipe 15 is opened, the third connecting pipe 18 is closed, and the buffer chamber piston 14 is pressed to the bottom. This allows the dispersion medium in the buffer chamber 13 to be transferred to the storage chamber 16. Because the present invention can strictly control the input amount during the dispersion medium generation process, the total amount of dispersion medium ultimately transferred to the storage chamber 16 is consistent during repeated experiments. After the transfer is completed, the second connecting pipe 15 is closed.

[0061] Furthermore, the dispersion medium generation control method of this embodiment further includes the following steps:

[0062] Step 4: Open the third connecting pipe 18 and the air outlet pipe 20 at the same time.

[0063] Step 5: Control the storage chamber piston 17 to move downward, and quantitatively control the amount of dispersed medium input into the detection chamber 19 by controlling the moving distance of the storage chamber piston 17 .

[0064] Specifically, in this embodiment, storage chamber piston 17 is driven by a motor. By precisely controlling the downward pressure distance of storage chamber piston 17 each time, a variety of dispersion medium environments with different concentrations can be created in detection chamber 19. The generation device of the present invention ensures that the total amount of dispersion medium generated each time is the same, and therefore the total amount of dispersion medium entering storage chamber 16 is the same, so the concentration of the resulting dispersion medium environment is always controllable.

[0065] Step 6: After the storage chamber piston 17 has finished moving, the air outlet pipe 20 and the third connecting pipe 18 are closed, and relevant experiments are performed through the dispersed medium in the detection chamber 19 .

[0066] Step 6 also includes the step of detecting the concentration of the dispersed medium in the detection chamber 19 by the concentration detection and calibration module 22. When the dispersed medium in the detection chamber 19 is stable, its concentration data can be collected to facilitate subsequent analysis and display of experimental data. It can also be used to verify whether the concentration of the dispersed medium in the detection chamber remains within a certain range during repeated experiments.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
