[0040] like Figure 5-Figure 8As shown, the cleaning component 3 includes a limiting cylinder 301, a guide rod 302 is fixedly installed on the outer surface of the limiting cylinder 301, the guide rod 302 is slidably installed in the guide groove 207, the guide groove 207 is opened on the outer surface of the liquid storage cylinder 201, a cleaning cylinder 311 is fixedly installed in the limiting cylinder 301, a cleaning cavity 305 is opened at the center of the cleaning cylinder 311, and the limiting cylinder 301 and the cleaning cylinder 311 are both slidably installed on the outer surface of the injection tube 203.

[0041] The cleaning chamber 305 of the cleaning cylinder 311 is sleeved on the outer surface of the outer surface of the injection tube 203 , and there is a distance between the cleaning chamber 305 and the outer surface of the injection tube 203 .

[0042] The outer surface of the cleaning cylinder 311 is connected with a water inlet pipe 303 and a water outlet pipe 304 . The water inlet pipe 303 is connected to the water tank 309 , while the water outlet pipe 304 is connected to the water tank 309 and the cleaning chamber 305 . The water tank 309 is opened in the cleaning cylinder 311 .

[0043] A pressurized nozzle 310 is fixedly installed in the cleaning chamber 305 , and the pressurized nozzle 310 is connected to the water storage tank 309 .

[0044] The pressurized nozzles 310 are arranged in a cross shape in the cleaning chamber 305 .

[0045] A cone cap 306 is fixedly installed on the lower surface of the limiting cylinder 301 , and a first hard film 307 and a second hard film 308 are fixedly connected inside the cone cap 306 . The second hard film 308 is located below the first hard film 307 .

[0046] The first hard film 307 and the second hard film 308 can be sealed against the surface of the injection tube 203 , and when the bottom slides out of the injection tube 203 , the first hard film 307 and the second hard film 308 will close and seal the cleaning chamber 305 .

[0047] The design of the limiting cylinder 301, the cleaning cylinder 311, the water inlet pipe 303, the water outlet pipe 304, the cleaning chamber 305 and the pressurized nozzle 310 is such that when the injection tube 203 is flushed, the second electric push rod 401 will push the limiting cylinder 301 and the cleaning cylinder 311 to slide down on the outer surface of the injection tube 203, and when the lower ends of the limiting cylinder 301 and the cleaning cylinder 311 slip out from the outer surface of the injection tube 203, the first hard film 307 and the second hard film 308 in the cone cap 306 on the lower surface of the limiting cylinder 301 will automatically reset and cover each other, and block and seal the sliding hole of the limiting cylinder 301 and the lower surface of the cleaning chamber 305 of the cleaning cylinder 311, and then the cleaning cylinder 311 can inject the external cleaning liquid into the water storage tank 309 through the water inlet pipe 303 connected to the outer surface, and the water storage tank When the cleaning liquid in 309 is filled and continuously injected, the cleaning liquid in the water tank 309 will be ejected from the small hole pressurized nozzle 310. Since the hole diameter of the pressurized nozzle 310 is small, the flow rate of the cleaning liquid will increase, resulting in a decrease in the pressure at the orifice of the pressurized nozzle 310. Due to the decrease in the pressure at the orifice, the cleaning liquid in the water tank 309 will be subjected to a greater pressure, thereby pushing the liquid to flow out, forming a pressurized effect and spraying on the outer surface of the injection tube 203, thereby achieving the cleaning operation of the injection tube 203 and improving the accuracy and purity of quantitative filling. The cleaning liquid ejected from the pressurized nozzle 310 will flow into the cleaning chamber 305, and then the outlet pipe 304 can be opened to allow the cleaning liquid and debris accumulated in the cleaning chamber 305 to flow out;

[0048] Through the design of the first hard film 307 and the second hard film 308, after the cleaning of the injection tube 203 is completed, the second electric push rod 401 will drive the limiting cylinder 301 and the cleaning cylinder 311 to slide upward on the outer surface of the injection tube 203 and expose the liquid outlet of the injection tube 203 to the outside, and at the same time, the first hard film 307 and the second hard film 308 on the lower surface of the limiting cylinder 301 will be pushed open by the injection tube 203 and stick to the outer surface of the injection tube 203, and the first hard film 307 and the second hard film 308 use the principle of the heart valve, that is, they are in a closed state when there is no force under normal circumstances, and will form a channel for the injection tube 203 to pass through only when subjected to external force.

[0049] According to the above technical solution, the working steps of this solution are summarized and sorted out: when filling the detection reagent, the first electric push rod 2 can be started to push the liquid storage cylinder 201 and the injection tube 203 on the lower surface of the mounting plate 205 to move vertically downward, and the injection tube 203 can be used to insert the reagent bottle below, and the liquid storage cylinder 201 will introduce the external detection reagent into the injection tube 203 through the liquid inlet tube 202 and inject it into the reagent bottle, so that it can achieve the filling operation;

[0050] When flushing the injection tube 203, the second electric push rod 401 will push the limiting cylinder 301 and the cleaning cylinder 311 to slide down on the outer surface of the injection tube 203. When the lower ends of the limiting cylinder 301 and the cleaning cylinder 311 slip out from the outer surface of the injection tube 203, the first hard film 307 and the second hard film 308 in the cone cap 306 on the lower surface of the limiting cylinder 301 will automatically reset and cover each other, and the sliding hole of the limiting cylinder 301 and the lower surface of the cleaning cavity 305 of the cleaning cylinder 311 will be blocked and sealed. Then the cleaning cylinder 311 can inject the external cleaning liquid into the water storage tank 309 through the water inlet pipe 303 connected to the outer surface, and the water storage tank 3 When the cleaning liquid in 09 is filled and continuously injected, the cleaning liquid in the water storage tank 309 will be sprayed out from the small hole of the pressurized nozzle 310. Since the hole diameter of the pressurized nozzle 310 is small, the flow rate of the cleaning liquid will increase, resulting in a decrease in the pressure at the orifice of the pressurized nozzle 310. Due to the decrease in pressure at the orifice, the part of the cleaning liquid in the water storage tank 309 will be subjected to a greater pressure, thereby pushing the liquid to flow out, forming a pressurized effect and spraying on the outer surface of the injection tube 203, thereby achieving the cleaning operation of the injection tube 203, and the cleaning liquid sprayed from the pressurized nozzle 310 will flow into the cleaning chamber 305 and flow out from the water outlet pipe 304.
