Title:
COVER BODY FOR LIQUID SAMPLING BOTTLE, LIQUID SAMPLING BOTTLE, LIQUID SAMPLING DEVICE, AND LIQUID INJECTION GUN
Document Type and Number:
WIPO Patent Application WO/2023/273454
Kind Code:
A1
Abstract:
A cover body for a liquid sampling bottle, a liquid sampling bottle, a liquid sampling device, and a liquid injection gun (5). The cover body comprises a base (1) provided with a liquid inlet (11) and a liquid outlet (12), a valve body (2) disposed on the base (1) and capable of selectively opening and closing the liquid inlet (11), and a sealing cover (3) detachably disposed on the base (1) to open and close the liquid outlet (12). The valve body (2) comprises a moving body (20) and a retaining structure. A liquid injection port (21) capable of being in fluid communication with a liquid injection tube (51) of the liquid injection gun (5) is formed on the moving body (20). The moving body (20) is movable in a first direction and has three stations sequentially arranged in the first direction, i.e., a first station for closing the liquid inlet (11), a second station at which the liquid injection port (21) communicates with the liquid inlet (11) to open the liquid inlet (11), and a third station for closing the liquid inlet (11). The retaining structure is configured to prevent the moving body (20) from moving in a second direction opposite to the first direction, so that the moving body (20) cannot return to the second station from the third station after sampling is completed, in order to inject liquid into a bottle. Therefore, the possibility of cheating during transportation is avoided.
