Abstract

The invention provides a liquid drawing device, comprising a shell, a liquid outlet pipe, a pressurization device, a pressure relief pipe and a switch group. An insertion pipe on the bottom of the shell can be hermetically inserted into a container bottle; an inner pipe is arranged in the insertion tube; the inlet end of the liquid outlet pipe is communicated with the inner pipe; the inlet end of the pressure relief pipe is communicated to the insertion pipe; and the switch group has a switch button for turning on / off the pressurization device, as well as a plug which can be interlocked with the switch button so as to plug up or leave the outlet end of the pressure relief pipe. Users can operate the pressurization device to drive air into the container bottle, so as to raise the air pressure in the container bottle and press liquid to be injected into a holding cup from the inner pipe and the liquid outlet pipe; moreover, when the pressurization device is turned off, the pressure relief pipe is not blocked by the plug any longer so as to allow high-pressure gas in the bottle to overflow, which can immediately stop the outflow of the liquid of the liquid outlet pipe.

Description

technical field [0001] The present invention relates to a liquid extractor, in particular to a liquid extractor capable of accurately extracting a required amount of liquid. Background technique [0002] Existing liquid extractors can be divided into two categories: manual extractors and electric extractors, which are described as follows: [0003] (1) The manual extractor includes an upper cover shell and a liquid container. The top of the upper cover shell is provided with a pressing part, and an air valve is installed in the shell. The bottom end of the air valve is provided with an air outlet pipe. At the bottom of the pressing part, there is a liquid outlet pipe in the liquid container, and the liquid inlet end of the liquid outlet pipe is close to the bottom of the container; when in use, inject liquid into the liquid container, and then install the upper cover shell airtightly on the In the liquid container, press the pressing part on the top of the upper cover shell...
