This utility model provides a geotechnical investigation sampling box, belonging to the field of geotechnical engineering investigation and sampling. The technical solution is as follows: a geotechnical investigation sampling box includes a soil sample box, with an upper and lower cover respectively installed at both ends. A label box is installed on the top of the upper cover. The label box includes a base and a lid. The bottom of the base is fixedly connected to the top of the upper cover, and the top of the base has a mounting groove for storing labels. The lid is located above the mounting groove, and the lid and base are rotatably connected. A locking mechanism is provided on the lid to lock it onto the base and seal the mounting groove. The beneficial effect of this utility model is that by encapsulating the labels inside the label box, it not only achieves independent protection for the labels but also effectively maintains their integrity over a long period.

The utility model provides an atomizer with a tar locking function and an electronic cigarette, and the atomizer comprises a housing which is provided with a tar storage cavity which is used for storing tobacco tar; the atomization assembly is arranged on the shell, the atomization assembly is provided with an atomization channel, and the atomization assembly is used for heating and atomizing tobacco tar entering the atomization channel; the blocking component is arranged on the shell in a sliding mode, the blocking component is provided with an oil passing channel and a limiting hole, the limiting hole extends in the sliding direction perpendicular to the blocking component, and the blocking component has an initial position and a working position; at the initial position, the oil storage cavity and the atomization channel are isolated by the blocking component; the working position is that the oil passing channel communicates with the oil storage cavity and the atomization channel; and the limiting component is detachably arranged in the limiting hole in a penetrating manner, so that the blocking component is limited to the initial position. According to the oil leakage prevention structure, accidental unlocking can be avoided, the locking reliability is remarkably improved, the blocking component can stably maintain the initial position, and the oil leakage prevention performance before use is effectively enhanced.
