technical field

The present invention relates to a liquid control device and its use method, in particular to a push-type liquid control device and its use method for controlling liquid supply.

Background technique

There are many push-type liquid control devices currently used, but most of them spray liquid or discharge liquid from the top. Some of our devices, such as the invented labware scrubber, require the flow of liquid to be controlled from below. Therefore, there is a need for a reusable push-type liquid control device for various types of products that can meet the requirements of the lower part of the liquid outlet, so as to facilitate the use and operation of these products.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Referring to Fig. 1, in order to solve the above problems, the technical solution of the present invention is: a push-type liquid control device and its use method, which are divided into two parts: the button 6 and the air pressure tube 13, and the feature is that the bottom of the button 6 is fixedly connected with a piston The rod 8 and the piston rod 8 are inside the compressed air pipe 13, and are tightly matched with the compressed air pipe 13; The end is connected with the compressed air gasket 12; within the stroke h range of the compressed air gasket 12, the side wall of the compressed air pipe 13 is connected with a liquid suction pipe 2; at the bottom of the compressed air pipe 13, there is a liquid discharge pipe sealing chamber 15, and The liquid pipe sealing chamber 15 communicates with 1-2 liquid discharge pipes 16, and a liquid discharge pipe sealing gasket 14 is arranged inside the liquid discharge pipe sealing chamber 15. The lower bottom of the piston rod 8 is also fixed with an elastic device 9, and the other end of the elastic device 9 is fixed on the elastic device fixed block 10 on the inner wall of the pressure pipe 13. The inside of the piston rod 8 is penetrated with a pressure pipe vent pipe 7, which is jointly opened at the button vent hole 5 together with the liquid storage container vent pipe 4 inside the button 6. The liquid suction pipe 2 is reinforced and fixed on the outside of the air pressure pipe 13 with the liquid pipet fixed frame 3, and its opening is at the 1/2h place of the air pressure gasket 12 strokes, and the liquid suction pipe 2 other end stretches into the liquid storage container 1 bottom. An elastic device 17 is installed on the lower bottom of the discharge pipe gasket 14 . The compressed air pipe 13 can be a straight pipe or a curved pipe with a certain radian; especially in the H length part, it can also be a pipe of any shape and a bend.

Operation instructions: When pressing, block the button vent hole 5 with your fingers, press down the button 6, and drive the piston rod 8 and the compressed air gasket 12 to go down. At this time, the internal air pressure of the air pressure pipe 13 increases, and a part of the gas enters the liquid storage container 1 through the liquid suction pipe 2 connected with it. Because the liquid storage container vent pipe 4 is blocked and the pressure increases, part of the liquid is pressed into the liquid storage container 1. In the liquid suction pipe 2; when the air pressure sealing pad 12 goes down and crosses the 2/1h position, the internal air pressure of the air pressure pipe 13 continues to increase until the maximum downward stroke, and the liquid pressed into the liquid suction pipe 2 remains still . The increased pressure inside the air pressure pipe 13 presses down the discharge pipe gasket 14, and the air pressure communicates with the external atmospheric pressure through the liquid discharge pipe 16 to reduce the pressure rapidly. At the same time, the elastic device 17 pushes the discharge pipe gasket 14 back to its original position. For, make pressure gas pipe 13 have to keep sealing.

After the button 6 is pressed to the maximum stroke, unclamp the finger blocking the button vent 5, and the air-pressing gasket 12 moves upward and resets quickly under the action of the elastic device 9 of the piston rod 8. At this time, the air pressure in the liquid storage container 1 is the same as the atmospheric pressure, and the liquid pressed into the liquid suction pipe 2 should flow back downwards. Negative pressure is generated inside, and after the air pressure sealing pad 12 goes up and crosses the 1/2h place, the liquid in the liquid suction pipe 2 is sucked into the air pressure pipe 13 inside.

In this way, pressing the button 6 repeatedly causes the liquid to be sucked into the air pressure pipe 13 from the liquid storage container 1 and then discharged from the liquid discharge pipe 16 .

Explanation: The shape of the present invention is not limited to those shown in the accompanying drawings. As long as the structure is the same or similar to the present invention, it is within the protection scope of the present invention.
