[0020] Tea leaves (green tea is selected in this embodiment) are placed in a test tube, and hot water is added to the test tube. Multiple test tubes with this configuration are installed on a transmission device, which is used to transfer the test tubes for testing. To achieve continuous heavy metal detection of green tea without affecting the heavy metal content of green tea samples in different test tubes, the following settings are implemented.

[0021] like Figures 1-6As shown, a detection device for green tea production that can provide early warning of heavy metal content includes a main frame 1, a cylinder 2 fixedly connected to the main frame 1, a piston rod 3 movably connected to the cylinder 2, a heavy metal detector 4 fixedly connected to the piston rod 3, a probe on the heavy metal detector 4, and a probe cleaning assembly connected to the main frame 1.

[0022] In a preferred configuration, the probe cleaning assembly includes two squeezing components. Each squeezing component includes a linkage bar 5, a sponge connector 6, a sponge body 7, a support bar 8, a bracket 9, a pressure box 10, an inclined block 12, and an extension rod 14. One end of the linkage bar 5 is rotatably connected to the piston rod 3, and the other end of the linkage bar 5 is rotatably connected to the sponge connector 6. The sponge body 7 is connected to the sponge connector 6. The bracket 9 is fixed to the main frame 1. The sponge connector 6, the pressure box 10, and the inclined block 12 are all slidably connected to the bracket 9. The support bar 8 is fixed to the heavy metal detector 4. A limiting groove 19 is provided on the pressure box 10. The inclined block 12 is connected to the bracket 9 through an elastic element 13. An inclined channel 18 is provided on the inclined block 12. The extension rod 14 is fixed to the piston rod 3. A rotating bar 20 is rotatably connected to the extension rod 14. A passive rod 24 is fixed to the pressure box 10.

[0023] Furthermore, a rack 16 is fixedly connected to the support 9, and a liquid storage chamber 21 and a liquid outlet chamber 17 are provided on the pressure box 10. The liquid outlet chamber 17 is connected to the bottom wall of the limiting groove 19. A guide wheel 22 is rotatably connected between the liquid storage chamber 21 and the liquid outlet chamber 17. A liquid guiding groove 23 is provided on the guide wheel 22, and a gear 15 is fixedly connected to the guide wheel 22, extending to the outside of the pressure box 10. A recycling box 11 is fixedly connected to the support 9, and the support 9 has two or more water collection holes. The liquid squeezed out from the sponge 7 passes through the water collection holes and enters the recycling box 11 for recycling, reducing the difficulty of subsequent cleaning.

[0024] To enable the movement of the inclined block 12, the outer wall of the pressure box 10 is provided with an inclined surface.

[0025] Optionally, the heavy metal detector 4 is equipped with a heavy metal sensor. The heavy metal sensor is used to detect the tea water inserted into the test tube in real time and convert the detected heavy metal content into an electrical signal output.

[0026] The cylinder 2 is equipped with a displacement sensor.

[0027] Regarding the choice of materials, the overall frame 1 is made of stainless steel, and the sponge body 7 is made of water-based polyurethane.

[0028] Regarding the further internal module configuration of the heavy metal detector 4, the heavy metal detector 4 includes a processing module and a wireless module. The processing module is used to analyze and judge the signals collected by the heavy metal sensor, realizing automatic identification and early warning of excessive heavy metal content. The wireless module is used to send the detection data to an external terminal or control platform in real time, realizing remote monitoring, data storage and traceability, and improving the informatization and intelligence level of the device.

[0029] Implementation process: In the initial state, such as Figure 1 As shown, two sponges 7 clamp the probe of the heavy metal detector 4, the inclined block 12 is inserted into the limiting groove 19 for limiting, the liquid guiding groove 23 on the guide wheel 22 faces upward, the liquid storage chamber 21 is filled with clean water, some of the clean water enters the liquid guiding groove 23, and the gear 15 is located above the rack 16.

[0030] A transmission device is used to transport test tubes containing tea leaves and tea water. When the test tube is transported to below the probe of the heavy metal detector 4, the transmission device stops transporting. The cylinder 2 controls the piston rod 3 to extend, thereby causing the heavy metal detector 4 to move down. The probe of the heavy metal detector 4 moves down and is inserted into the test tube to detect heavy metals in the tea water.

[0031] During the extension of piston rod 3, the linkage bar 5 drives the sponge connector 6 and sponge body 7 to move horizontally, thereby moving the two sponge bodies 7 away from each other. When the sponge body 7 moves to below the pressure box 10, the rotating bar 20 on the extension rod 14 is inserted into the inclined channel 18 but does not move down to below the inclined channel 18, thereby pushing the inclined block 12 to overcome the elastic force of the elastic element 13 and move away from the limiting groove 19. After the inclined block 12 is separated from the limiting groove 19, the pressure box 10 falls down under its own gravity, thereby pressing on the sponge body 7 and squeezing out the liquid on the sponge body 7, thereby cleaning the sponge body 7 so that the sponge body 7 can continuously clean the probe of the heavy metal detector 4.

[0032] When the pressure chamber 10 falls down, the gear 15 meshes with the rack 16, causing the rack 16 to drive the gear 15 to rotate. The gear 15 then drives the guide wheel 22 and the liquid guide tank 23 to rotate about 180 degrees, causing a certain amount of clean water in the liquid guide tank 23 to fall into the liquid outlet chamber 17. The clean water then flows out of the liquid outlet chamber 17 to the sponge 7 to rinse the sponge 7. This improves the cleaning quality of the sponge 7 when the pressure chamber 10 squeezes the sponge 7, allowing more tea to be squeezed out of the sponge 7, while not wasting too much clean water in the liquid storage chamber 21.

[0033] Then, the piston rod 3 is shortened, the probe is moved upward and removed from the test tube, and the two sponges 7 approach each other to squeeze the probe of the heavy metal detector 4 and suck away the tea on the probe. The gear 15 reverses, thereby causing the liquid guide groove 23 on the guide wheel 22 to reverse and reset. The liquid guide groove 23 is refilled with a certain amount of clean water for the next cleaning of the sponge 7. The inclined surface on the pressure box 10 pushes the inclined block 12 to move against the elastic force of the elastic element 13. Then the inclined block 12 and the side wall of the pressure box 10 abut against each other. When the limiting groove 19 moves to the same horizontal plane as the inclined block 12, the inclined block 12 is inserted into the limiting groove 19 under the action of the elastic force of the elastic element 13 to limit the pressure box 10.

[0034] Then, the next test tube is moved to the bottom of the heavy metal detector 4 using a transmission device, and the heavy metal content in the tea is detected using the same method as above, thereby detecting the heavy metal content in the tea.

[0035] This invention relates to a probe cleaning assembly linked to a heavy metal detector 4, mounted on the overall frame 1. During the up-and-down movement of the piston rod 3 driven by the cylinder 2, the linkage bar 5, sponge connector 6, and sponge body 7 simultaneously undergo relative opening and closing motion. As the probe completes one test and moves upward, the two sponge bodies 7 perform a squeezing wipe on the probe, effectively removing residual tea from its surface and preventing tea residue from the previous test tube from interfering with the test results of the next test tube. This structure achieves automatic cleaning without manual intervention, ensuring the heavy metal detector 4 maintains a clean probe throughout continuous, multi-test-tube testing. This fundamentally solves the problems of cross-contamination of residual probe liquid, distorted test results, and poor repeatability in existing technologies, significantly improving detection accuracy and reliability. This application also utilizes the coordinated operation of the pressure box 10, inclined block 12, elastic element 13, gear 15, rack 16, guide wheel 22, and liquid guiding groove 23 to enable the probe cleaning process to not only include mechanical squeezing but also a quantitative rinsing function, thus avoiding waste of clean water and being environmentally friendly and energy-saving. When the pressure box 10 falls and squeezes the sponge 7, the gear 15 meshes with the rack 16, driving the guide wheel 22 to rotate, causing a quantitative amount of clean water in the liquid guiding groove 23 to flow into the liquid outlet chamber 17 and spray onto the surface of the sponge 7, achieving synchronous rinsing. The waste liquid after cleaning is collected and recycled through the recycling box 11 to avoid overflow pollution. This structure, while ensuring the cleaning effect, also achieves an automatic cleaning function with controllable water volume, structural linkage, and no need for additional power, making the probe cleaning process highly coupled with the detection action. It is suitable for batch detection scenarios in production lines and significantly improves the continuity, automation, and industrial applicability of heavy metal detection in green tea.
