Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] Reference Figures 1 to 6As shown, this is a preferred embodiment of the photocatalytic reaction test chamber structure with switchable spectrum, including a test component 3. A support 1 is fixedly connected to the bottom of the test component 3, and a light source component 2 is disposed at the front end of the test component 3. The light source component 2 includes a sealing cover 201, a fixing block 202 fixedly connected to the front end of the sealing cover 201, a rotating block 203 rotatably connected inside the fixing block 202, and a lead screw 204 fixedly connected to the front end of the rotating block 203. The front end of the lead screw 204 passes through the front end of the fixing block 202 and is fixedly connected to a knob 205. A threaded sleeve 206 is threaded to the middle of the rod 204. A plurality of equidistant first connecting blocks 207 are fixedly connected to the outer wall of the threaded sleeve 206. A connecting shaft arm 208 is hinged to the end of the first connecting block 207 away from the threaded sleeve 206. A second connecting block 210 is hinged to the end of the connecting shaft arm 208 away from the first connecting block 207. A sliding rod 209 that is slidably connected to the sealing cover 201 is fixedly connected to the end of the second connecting block 210 away from the connecting shaft arm 208. An L-shaped locking block 211 is fixedly connected to the end of the sliding rod 209 away from the second connecting block 210.

[0027] When the knob 205 is rotated, the lead screw 204 rotates, causing the threaded sleeve 206 to move back and forth. The connecting shaft arm 208 causes the L-shaped locking block 211 to slide along the slide groove. At the same time, the rotation of the lead screw 204 drives the threaded transmission of the threaded sleeve 206 to convert the rotational motion into linear motion. In conjunction with the connecting shaft arm 208, the first connecting block 207, the second connecting block 210, and the sliding rod 209, the displacement is amplified, improving the operating efficiency.

[0028] The rear end of the sealing cover 201 is fixedly connected to the mounting base 212, and the rear end of the mounting base 212 is threadedly connected to the test lamp 213;

[0029] The test lamp 213 is easy to disassemble and replace due to its threaded connection. By replacing it with different types of light sources, such as LEDs of different wavelengths, the spectrum can be switched to meet the diverse needs of photocatalytic reaction testing.

[0030] Multiple equidistant fixed shafts 214 are fixedly connected to the rear end of the sealing cover 201 and around the outside of the mounting base 212. A reflective mirror 215 is fixedly connected to the rear end of the fixed shaft 214. The reflective mirror 215 is inclined.

[0031] The tilted reflective mirror 215 can reflect the light emitted by the test lamp 213, reducing light scattering loss, allowing the photocatalytic reaction module to receive more uniform and stronger illumination, improving test accuracy, ensuring that light energy effectively covers the test area, and enhancing light utilization.

[0032] Test component 3 includes test chamber 301, inside which a photocatalytic reaction test module and its electronic components 303 are fixedly connected, and at the front end of test chamber 301 a sealing strip 302 is fixedly connected.

[0033] The sealing strip 302 and the sealing cover 201 work together to form a closed space, preventing external dust and impurities from entering the test chamber 301 and ensuring that the photocatalytic reaction takes place in a controlled environment. At the same time, the test module and electronic components are built into the test chamber 301, which facilitates circuit layout and signal acquisition and improves system stability.

[0034] The test chamber 301 and the sealing strip 302 are both compatible with the sealing cover 201;

[0035] The sealing cover 201 is tightly fitted to the test chamber 301 to prevent light leakage or gas leakage, ensuring the reliability of the test environment and ensuring the stability of parameters such as light intensity and gas concentration, thus providing accurate environmental conditions for photocatalytic reaction testing.

[0036] The outer wall at the front of the test chamber 301 is provided with a slot for the L-shaped card block 211;

[0037] When the L-shaped card block 211 is inserted into the card slot, a stable mechanical connection is formed, preventing the sealing cover 201 and the test chamber 301 from shifting during the test, ensuring optical path alignment and structural stability, and guaranteeing the safety and accuracy of the test process.

[0038] The front end of the sealing cover 201 is provided with a groove for adapting to the sliding rod 209;

[0039] The sliding rod 209 is provided with a movement track by the slide groove, which restricts its movement direction and allows it to move only along a specific axis to avoid deviation during movement. This ensures that the L-shaped locking block 211 can smoothly engage or disengage from the slot, making the installation and disassembly of the sealing cover 201 and the test chamber 301 smoother.

[0040] The photocatalytic reaction test module and its electronic components 303 are configured in correspondence with the test lamp 213;

[0041] By setting the corresponding parameters, the light emitted by the test lamp 213 is ensured to directly illuminate the photocatalytic reaction area, avoiding waste of light energy. At the same time, it facilitates the real-time monitoring of reaction conditions by the photocatalytic reaction test module and its electronic components 303, such as light intensity sensors and temperature sensors, improving data acquisition accuracy and providing reliable data support for photocatalytic reaction testing.

[0042] Specific implementation process: First, install the light source assembly 2: Install the test lamp 213 onto the mounting base 212 at the rear end of the sealing cover 201 via a threaded connection. Select a light source of different wavelengths, such as ultraviolet light or visible light, according to the test requirements, and ensure that the test lamp 213 corresponds to the position of the photocatalytic reaction test module and its electronic components 303. Next, close the sealing cover 201: Align the sealing cover 201 with the front end of the test chamber 301, so that the sealing strip 302 fits tightly with the sealing cover 201 to form a sealed space. Then, rotate the knob 205 to drive the lead screw 204 to rotate. Due to the threaded transmission, the screw sleeve 206 moves backward along the axial direction of the lead screw 204. Through the linkage of the first connecting block 207, the connecting shaft arm 208, and the second connecting block 210, the sliding rod 209 is pushed to slide backward along the sliding groove at the front end of the sealing cover 201, finally causing the L-shaped locking block 211 to be embedded in the locking groove at the front of the test chamber 301, completing the sealing. Mechanically lock the cover 201 to the test chamber 301; then, start the test process: turn on the power, the test lamp 213 emits light, and the tilted reflector 215 reflects and focuses the light into the test chamber 301, ensuring that the photocatalytic reaction area is uniformly illuminated. The photocatalytic reaction test module and its electronic components 303 synchronously monitor parameters such as light intensity, temperature, and gas concentration during the reaction process and transmit the data to the external control system. When it is necessary to switch the spectrum, rotate the knob 205 in the opposite direction, and the lead screw 204 drives the screw sleeve 206 to move forward. Through the linkage mechanism, the L-shaped locking block 211 is disengaged from the slot. Remove the sealing cover 201 and replace the test lamp 213 with a different wavelength. Repeat the above installation steps to complete the spectrum switching. After the test, disassemble and clean: rotate the knob 205 again to release the L-shaped locking block, remove the sealing cover 201, and clean the inside of the test chamber 301 to prepare for the next test.
