Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical detection equipment technology, and in particular to a sample extraction and sealing device for organic compound detection. Background Technology
[0002] With the continuous advancement of science and technology and the increasing awareness of environmental protection, the detection of organic compounds is becoming increasingly important in fields such as environmental monitoring, food safety, and drug testing; effective sample extraction and sealing processes are crucial to ensuring the accuracy and reliability of test results.
[0003] Traditional organic compound detection sample extraction and preservation often relies on multiple independent and scattered devices. Each of these devices occupies a certain amount of space, resulting in a large overall footprint. For laboratories with limited space, this not only increases the difficulty of layout but also restricts the placement and use of other experimental equipment, reducing the overall utilization rate of the laboratory space. Furthermore, due to the dispersed nature of the devices, operators need to frequently switch between different devices during sample extraction and preservation, making the process cumbersome and prone to errors. Secondly, in the traditional sample extraction process, locating specific samples for preservation often relies on manual searching. After locating the sample, it is difficult to accurately control the drip volume, which can easily lead to sample leakage. This not only wastes and contaminates the sample but also affects subsequent test results. Utility Model Content

[0027] like Figure 1-4As shown, this embodiment provides an organic compound detection sample extraction and sealing device, including: a sealing box 1, a storage mechanism 2 disposed within the sealing box 1, an extractor 7 disposed on one side of the storage mechanism 2, and a control terminal 10 disposed through the top working surface of the sealing box 1; the sealing box 1 is hollow inside and is divided into two accommodating spaces by an electric partition 15, with the storage mechanism 2 and the extractor 7 located in the two accommodating spaces respectively. The electric partition 15 not only effectively separates the accommodating spaces inside the sealing box 1 but also improves space utilization; the space between the electric partition 15 and the sealing box 1 is a transfer channel 16; the sealing box 1 is equipped with a quick-retrieval mechanism 5, which is used to retrieve the sealing component 9 that is clipped onto the storage mechanism 2. The quick-retrieval mechanism 5 can accurately and quickly retrieve the sealing component 9, shortening the sample extraction time. After the sealing component 9 is removed by mechanism 2, it is placed on the fixed seat 8 through the transfer channel 16 to wait for the sample to be removed, which improves work efficiency. A sampling window 14 is opened at the top of the sealing box 1, and the sampling window 14 corresponds to the position of the fixed seat 8 set on the bottom wall of the sealing box 1. After extraction, the operator removes the extractor 7 through the sampling window 14 and tests the organic compound sample inside. The control terminal 10 is used to control the working status of each component. The setting of the control terminal 10 can accurately control each component, improve the intelligence and automation level of the device, and thus simplify the operation process and improve the accuracy and convenience of the work. Furthermore, a sealing door 12 is opened on one side of the working surface of the sealing box 1, and rubber pads 13 are provided at the four corners of the bottom. The setting of the sealing door 12 makes it convenient for the operator to replace the sample in time, and when the sealing door 12 is closed, it completely isolates the sample from the outside world, preventing sample contamination.

At this time, if there is no sealing component 9 in the groove 202, the light emitted by the transmitter can successfully propagate to the receiver. The receiver receives a stable light signal, converts it into a corresponding electrical signal, and transmits it to the control terminal 10. The control terminal 10 determines that the groove 202 is empty based on the received electrical signal, otherwise it is empty because there is a sealing component 9.
