Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1-3 As shown in the figure, the disinfectant sampling device provided by the present invention comprises a barrel 100 and a plurality of suction units, and the suction units are used to suck the disinfectant sample from the disinfectant production tank.

[0026] The front port of the cylinder 100 is detachably blocked with an end cap 200, and a handle 300 is provided at the bottom of the rear end of the cylinder 100. Specifically, each suction unit includes an internal threaded connecting pipe 410, a liquid suction pipe 420, an air pump 430, and an air suction pipe 440. The end cap 200 can be connected to the front port of the cylinder 100 by a snap-on method. For example, the inner diameter of the end cap 200 is equal to the outer diameter of the cylinder 100, an annular groove is arranged around the inner wall of the end cap 200, and an annular convex ring is arranged around the outer wall of the front end of the cylinder 100. In the process of sleeve the end cap 200 on the front end of the cylinder 100, the annular convex ring is inserted into the annular groove, so that the end cap 200 can be prevented from falling off easily. When the end cap 200 needs to be removed, it can be removed with a little force.

[0027] The internal threaded connection tube 410 is arranged at the outer bottom of the cylinder 100, and the internal threaded connection tube 410 is used to connect with the sampling bottle 1. The bottle mouth of the sampling bottle 1 is generally provided with an external thread, which can be conveniently connected with the internal threaded connection tube 410.

[0028] A plurality of suction units are provided, so that a plurality of sampling bottles 1 can be connected. Thus, the sampling device provided by the utility model can be used to sequentially take out samples from a plurality of disinfectant production tanks into corresponding sampling bottles 1, thereby improving the sampling efficiency.

[0029] The pipette 420 is arranged inside the cylinder 100, the front end of the pipette 420 extends from the end cover 200 to the outside of the cylinder 100, and the rear end of the pipette 420 extends from the internal threaded connecting tube 410 to the outside of the cylinder 100. The pipette 420 adopts a telescopic tube.

[0030] The air pump 430 is arranged at the inner rear part of the cylinder 100, the air suction pipe 440 is arranged at the inner part of the cylinder 100, the front end of the air suction pipe 440 extends from the internal threaded connection pipe 410 to the outside of the cylinder 100, and the rear end of the air suction pipe 440 is connected to the air pump 430. Specifically, the air suction pipes 440 of each suction unit are connected to the same air pump 430 through a multi-port joint. Further, the air pump 430 is arranged in the installation cavity at the inner rear part of the cylinder 100, and the rear end of the cylinder 100 is provided with an air hole 110 that connects the installation cavity with the outside, and the gas sucked by the air pump 430 is led out of the cylinder 100 from the air hole 110.

[0031] In order to simplify the equipment structure, the internal threaded connecting pipes 410 of each suction unit are arranged at intervals along the length direction of the cylinder 100.

[0032] In order to facilitate identification of the corresponding relationship between the air suction pipe 440 and the internal threaded connecting pipe 410 on the end cover 200 , auxiliary markings are usually provided around the liquid suction pipe 420 and the internal threaded connecting pipe 410 .

[0033] Before sampling, the operator connects the sampling bottle 1 to each internal threaded connection pipe 410. When arriving at the first disinfectant production tank, the operator connects the disposable long hose to the pipette 420 on the end cap 200, and then puts the other end of the long hose into the disinfectant production tank and immerses it in the disinfectant. Then, the air pump 430 can be started, and the air pump 430 extracts the air in the sampling bottle 1, so that the pressure in the sampling bottle 1 is reduced, and then the disinfectant in the disinfectant production tank is sucked into the sampling tube through the long hose and the pipette 420. After the required volume of disinfectant is sucked into the sampling tube, the air pump 430 is turned off, and the corresponding long hose is removed from the pipette 420 and extracted from the disinfectant production tank. The operator can continue to move to the next disinfectant production tank and take samples using the same steps.

[0034] After sampling is completed and each sampling bottle 1 is removed, the sampling device provided by the utility model needs to be cleaned to prevent interference with the sample of the next sampling. Figure 3-Figure 5As shown in , the sampling device provided by the utility model also includes a flushing cylinder 510 and a flushing cylinder pipe 520 arranged at the bottom of the outer side of the cylinder body 100. The flushing cylinder pipe 520 surrounds each internal thread connection pipe 410 on the inner side, and the flushing cylinder pipe 520 is used to be detachably connected with the flushing cylinder 510. When cleaning, the flushing cylinder 510 is buckled on the flushing cylinder pipe 520, and the end cover 200 is removed, so that the pipe mouth of the liquid suction tube 420 on the end cover 200 is immersed in the cleaning liquid, and then the air pump 430 is started, and the cleaning liquid can be sucked into the flushing cylinder 510, and the liquid suction tube 420 is cleaned during the flow of the flushing liquid. In the utility model, a detachable end cover 200 is arranged at the front end of the cylinder body 100, which can not only immerse the front end of the liquid suction tube 420 with the end cover 200 in the cleaning liquid for cleaning, but also make the sampling device and the flushing cylinder 510 in an upright state to ensure that the cleaning liquid can be smoothly sucked into the flushing cylinder 510.

[0035] The flushing cylinder 510 and the flushable cylinder connecting pipe 520 are connected by interference fit, and a sealing ring may be provided on the outer wall of the flushing cylinder connecting pipe 520 to improve the sealing between the flushing cylinder 510 and the flushable cylinder connecting pipe 520 .

[0036] In the sampling device provided by the utility model, the bottom of the handle 300 is fixedly connected to the base 600, and the base 600 is located below the cylinder 100. The air pump 430 is powered by a battery, and the battery is placed in the inner cavity of the handle 300, so that the center of gravity of the sampling device is lowered, so that the sampling device can remain upright when placed on a table.
