[0032] Multiple nozzles 7 are interconnected with the pipe sleeve 6. A duct 8 interconnected with the pipe sleeve 6 is fixedly installed on the outer side of the pipe sleeve 6. The end of the duct 8 away from the U-shaped tube 5 is fixedly connected to a blower 9. A drive motor 10 is fixedly installed on the upper end of the blower 9. The drive motor 10 is used to drive the impeller in the blower 9 to rotate, and the drive shaft of the drive motor 10 is fixedly connected to the mounting shaft of the impeller in the blower 9. A duct 2 11 interconnected with the pipe is fixedly installed on the air inlet end of the blower 9. The connection between the drive motor 10 and the sensor 4 is an electrical connection.

[0033] Working principle: When the inspector uses the faucet 3 for cleaning, the inspector inserts his hand into the pool 2, the sensor 4 senses the hand and sends a signal, then the faucet 3 releases clean water, and the drive motor 10 runs synchronously, the drive motor 10 drives the impeller inside the blower 9 to rotate, and the gas is discharged through multiple nozzles 7, forming a wind wall inside the pool 2, so that when the inspector is cleaning, the wind wall will block water droplets from splashing to the outside of the pool 2, which can effectively prevent the inspection table and the inspector's clothes and exposed upper skin from being contaminated with the experimental solution.

[0034] Example 2: Please refer to Figure 4-Figure 6 This embodiment further explains the first embodiment. The liquid adding component includes a liquid storage tank 12 fixedly installed inside the detection table body 1, and the blower 9 is fixedly installed at the center of the upper end of the liquid storage tank 12. A conduit three 13 connected to the liquid storage tank 12 is fixedly installed on the outer side of the liquid storage tank 12, and the conduit three 13 is close to the lower end of the liquid storage tank 12. The liquid storage tank 12 is used to hold disinfectant. A positioning ring 14 is fixedly installed inside the liquid storage tank 12. A plurality of metal sheets 15 equidistantly distributed in a circle are fixedly installed on the inner wall of the positioning ring 14, and the height of the metal sheets 15 is less than the depth of the liquid storage tank 12.

[0035] The lower end of the impeller mounting shaft of the blower 9 is fixedly connected with a rotating shaft 16, and the rotating shaft 16 is rotatably connected to the liquid storage tank 12 through a sealed bearing, and the lower end of the rotating shaft 16 is fixedly connected with a connecting seat 17, and a plurality of circumferentially equidistantly distributed shifting rods 18 are fixedly embedded on the outer side of the connecting seat 17, and the cross-sectional shape of the shifting rod 18 is circular, so that the resistance to the rotation of the shifting rod 18 in the liquid is small, and a triangular stopper 19 is fixedly embedded at one end of the shifting rod 18 away from the connecting seat 17, and the connection between the triangular stopper 19 and the plurality of metal sheets 15 is a rotational contact.

[0036] In this embodiment: since the gas enters the blower 9 through the second conduit 11, the end of the second conduit 11 away from the blower 9 is embedded in the upper end of the liquid storage tank 12, so that the gas entering the blower 9 needs to pass through the disinfectant in the liquid storage tank 12 first, and the gas passing through the disinfectant will carry disinfectant molecules. At the same time, the impeller in the blower 9 will drive multiple levers 18 and triangular blocks 19 to rotate through the rotating shaft 16 during the rotation process. The triangular block 19 contacts multiple metal sheets 15 during the rotation process, causing the metal sheets 15 to deform. When the triangular block 19 rotates away from the metal sheet 15, the metal sheet 15 will rebound under its own performance, causing the metal sheet 15 to vibrate, thereby generating a large amount of disinfectant mist on the surface of the disinfectant in the liquid storage tank 12, further increasing the content of disinfectant molecules in the gas entering the blower 9, which is beneficial to disinfect the unwashed part of the personnel's hands located on the lower side of the wind wall.

[0037] Example 3: Please refer to Figure 5 This embodiment further explains Example 2, the filter assembly includes a water tank 20 installed on the left side of the liquid storage tank 12, and the end of the conduit three 13 away from the liquid storage tank 12 is fixedly embedded in the center of the upper end of the water tank 20, and a conduit four 21 connected to the water tank 20 is fixedly installed on the outside of the water tank 20, and the conduit four 21 is close to the lower end of the water tank 20, and the end of the conduit four 21 away from the water tank 20 is fixedly connected to an air pump 22, and the air pump 22 is used to deliver gas into the water tank 20.

[0038] A valve 23 connected to the water tank 20 is fixedly installed on the outer side near its lower end, and a sewage pipe 24 connected to the water tank 20 is fixedly installed on the end of the valve 23 away from the water tank 20. A liquid adding pipe 25 connected to the water tank 20 is fixedly installed on the upper ends of the liquid storage tank 12 and the water tank 20. A sealing cover 26 is threadedly sleeved on the upper end of the liquid adding pipe 25 to prevent gas from leaking through the liquid adding pipe 25.

[0039] Anti-reversal components are installed inside the catheter three 13 and the catheter four 21. The anti-reversal components include a perforated plate 27 fixedly embedded in the catheter three 13 and the catheter four 21.

The hollow ball 29 can move inside the conical tube 28 when driven by gas or liquid, and the diameter of the hollow ball 29 is larger than the diameter of the left end of the conical tube 28.

[0040] In this embodiment: the air pump 22 runs to send air into the water tank 20 through the conduit four 21. After the air contacts the clean water inside the water tank 20, it enters the liquid storage tank 12 through the conduit three 13. In the process of the air passing through the clean water, the clean water absorbs dust and impurities in the gas, which is helpful to filter out dust or impurities in the air and prevent the gas and impurities in the air from entering the liquid storage tank 12 and causing contamination to the disinfectant.

[0041] Example 4: Please refer to Figure 7 , Figure 8 This embodiment further illustrates other embodiments. Two symmetrically distributed guide components are installed on the inner wall of the water pool 2, and the two guide components are respectively installed on the upper sides of multiple nozzles 7. The guide component includes a rotatable guide plate 30. The guide plate 30 is used to change the flow direction of the gas ejected from the nozzle 7. The two ends of the guide plate 30 are movably abutted with a positioning seat 31, and the positioning seat 31 is fixedly connected to the water pool 2. The guide plate 30 is rotatably connected to the positioning seat 31 through a connecting shaft 32. The outer sides of both ends of the connecting shaft 32 are fixedly sleeved with rubber sleeves 33, and the rubber sleeves 33 are located inside the positioning seat 31.

The elastic band 36 is used to seal the gap between the guide plate 30 and the pool 2.

[0043] In this embodiment: when the inspector is cleaning the inside of the pool 2, the inspector rotates the guide plate 30 downward. After the rotation, the guide plate 30 changes the flow direction of the gas sprayed from the nozzle 7, so that the gas flows along the side wall of the pool 2. At this time, the gas containing disinfectant molecules is blown on the side wall of the pool 2, which can directly disinfect the side wall of the pool 2. When a large amount of disinfectant droplets are attached to the side wall of the pool 2, the inspector can wipe other areas in the pool 2 with a rag dipped in disinfectant, thereby facilitating the disinfection of the pool 2 over a large area.
