Sheath type horn mouth sampling head

The utility model relates to a sheath type horn mouth sampling head which comprises a sampling head, one end of the sampling head is fixedly connected with a third sampling tube, the inner diameter of the left side of the sampling head is slightly larger than the outer diameter of the third sampling tube, the sampling head is conical, the inner diameter of a right side port of the sampling head is far smaller than that of a left side port, and the port with the smaller inner diameter is used for targeted sampling. The outer side of the sampling head is sleeved with a sleeve, the left end of the sampling head slightly extends out of the sleeve, the right end of the sleeve is fixedly connected with a horn mouth, and the horn mouth is used for sucking a fluid target sample in a large range. According to the utility model, fluid is sucked by arranging the horn head which is inclined by 15 degrees relative to the sleeve, so that the efficiency of the device is greatly improved, and target fluid is collected in the
