To make the objects, technical solutions and advantages of the present invention clearer, the drawings of the present invention are combined to clearly and completely describe the technical solutions of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The automatic uncovering and sample storing device 100 for the liquid hazardous chemical substance of the present invention is described below with reference to fig. 1 to 4, and comprises: the box 110, the movable door 120, the carrying device 130 and the executing device.
Specifically, the housing 110 has a storage cavity 111, an access port 112, and a sampling port 113. The pick-and-place port 112, the sampling port 113 and the storage cavity 111 are all communicated. It will be appreciated that the access opening 112 may allow the storage chamber 111 to communicate with the outside (where "outside" may refer to the interior space of the device connected to the housing 110, or may refer to the environment outside the housing 110). In some examples, the sampling port 113 is in communication with a sample output device such that a sample within the sample output device can be placed onto the carrier 130 through the sampling port 113. In some embodiments, the interior surface of the storage chamber 111 and the surface of the sample cup 150 are coated with a material that prevents corrosion, increasing the durability of the device and the adaptability of the device to different sample types.
