Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1 to 45, the embodiment of the present invention provides a sampling device, which is used for sampling the object to be sampled in the accommodating cavity of the accommodating barrel. Specifically, the sampling device in this embodiment includes a sampling mechanism 10, and the sampling mechanism 10 is used for sampling an object to be sampled in the accommodating cavity; the sampling mechanism 10 comprises a sampling shell 11 and a sampling piece 120, wherein the sampling shell 11 is provided with a sampling cavity 111, and a communication port 112 is arranged on the sampling shell 11 so as to enable the sampling cavity 111 to be communicated with a containing cavity of a containing barrel through the communication port 112. The sampling member 120 is movably disposed so that the sampling member 120 has an initial position and a sampling position, and the sampling member 120 has a sample storage portion for receiving a sample. When the sampling member 120 is in the initial position, the sampling member 120 is positioned within the sampling cavity 111; when the sampling member 120 is in the sampling position, the sampling member 120 is positioned within the receiving cavity to collect the sample through the sample reservoir. In a specific embodiment, the receiving bucket comprises a drainage shell 30, and the receiving cavity is a drainage cavity 31 enclosed by the drainage shell 30. In one embodiment, the sample reservoir may be a sample reservoir or a sampling tray.

The sampling device in this embodiment further includes a sampling mechanism 20, and the sampling mechanism 20 is used for sampling the samples in the sample storage portion. The sampling mechanism 20 includes a sampling arm 213 and a sampling driving part, the sampling arm 213 is used for sampling the sample in the sample storage part, and the sampling driving part is in driving connection with the sampling arm 213 so as to drive the sampling arm 213 to sample through the sampling driving part. In this way, better sampling can be facilitated to better reduce contamination of the sample.

With the sampling device provided in this embodiment, as shown in fig. 1 to 3, when sampling is not needed, the sampling member 120 is in the initial position, and the sampling member 120 is located in the sampling cavity 111, so as to avoid contamination of the sampling member 120 by the excretory substance in the excretory cavity 31. When sampling is needed, the sampling member 120 moves to the sampling position, at this time, the sampling member 120 is located in the excretion cavity 31 and collects the excrement through the sample storage part of the sampling member 120, and after the excrement is collected, the sampling member 120 moves to the initial position again. As can be seen from the above operation process of sampling, the sampling member 120 in this embodiment realizes sampling by switching the movement between the sampling cavity 111 and the excretion cavity 31, so as to avoid the situation that the sampling member 120 is easily contaminated in the excretion cavity 31 for a long time, thereby facilitating obtaining an effective excrement sample. Therefore, through the technical scheme that this embodiment provided, can solve the technical problem that the closestool among the prior art can cause serious pollution to the sample when sampling the excrement.

As shown in fig. 3 to 7, in order to facilitate the sampling member 120 to move to the initial position or the sampling position, in a specific embodiment, the sampling device further includes a first sampling driving mechanism 13, and a driving end of the first sampling driving mechanism 13 is in driving connection with the sampling member 120 to drive the sampling member 120 to move through the first sampling driving mechanism 13.
