Problems solved by technology

This device is often used in conjunction with washing liquid bottles, toilet water bottles, curry water bottles and other containers that need to press out the liquid in the bottle. Since the position between the liquid outlet pipe and the gland is fixed, it is impossible to adjust the liquid outlet pipe. The distance between the gland and the gland, when the liquid outlet pipe is pressed down, the amount of liquid squeezed out is fixed. necessary waste

Embodiment Construction

[0008] The present invention will be further described in detail in conjunction with the accompanying drawings. The liquid outlet pipe 1 of the present invention is slid up and down in the hole at the top of the gland 4, and a liquid outlet adjustment device is provided between the gland 4 and the upper end of the liquid outlet pipe 1. The liquid outlet regulating device includes an outer cover 2, the inner side of the outer cover 2 is provided with an internal thread, the outer side of the gland 4 is provided with an external thread 3 matching the inner side of the outer cover, and the internal thread and the external thread 3 are screwed together. The hole at the top of the outer cover 2 is opposite to the hole at the top of the gland 4 , and the outlet pipe 1 slides up and down and is connected in the hole at the top of the outer cover 2 .

[0009] When in use, according to the amount of liquid you usually need, rotate the outer cover 2 to adjust the distance between the upp...

Abstract

The invention discloses a pressing suction device capable of adjusting the liquid outlet amount. The device comprises a gland and a liquid outlet tube. The liquid outlet tube is in vertical sliding connection with a hole in the top of the gland. The device is characterized in that a liquid outlet adjusting unit is arranged between the gland and the liquid outlet tube and comprises an outer cover which is screwed to the outside of the gland, a hole formed in the top of the outer cover is aligned with the hole in the top of the gland, and the liquid outlet tube is in vertical sliding connection with the hole in the top of the outer cover. The device has the advantages that the outer cover is screwed to the outside of the gland, and the distance between the upper end of the liquid outlet tube and the outer cover can be adjusted by rotating the outer cover, the pressing height of the liquid outlet tube can be controlled, the liquid outlet amount can be controlled effectively by controlling the pressing height of the liquid outlet tube, the liquid outlet amount can be adjusted, and unnecessary waste can be prevented effectively.

Description

technical field [0001] The invention relates to a liquid lifting device, in particular to a pressing liquid suction device. Background technique [0002] Push-type liquid suction device, which is mainly composed of gland, catheter, liquid inlet valve, spring, exhaust valve, piston, liquid outlet pipe, liquid storage cylinder, etc. It works on the same principle as a piston pump. It uses the movement of the piston to discharge the air in the liquid storage cylinder, causing the difference in air pressure inside and outside, so that the liquid rises under the action of air pressure and is discharged from the liquid outlet pipe. When the liquid pipe is pressed down by hand, the spring is compressed so that the liquid inlet valve is closed downward, and at the same time, due to the downward movement of the piston, the exhaust valve is opened at this time, and the liquid in the liquid storage cylinder flows out of the liquid pipe from the liquid pipe. Outside; when the lever is...
