Abstract

A hand-pressing vacuum device is composed of two sets of movable pistons, one set of fixed pistons and two sets of compression springs, which are arranged in a coaxial manner, and is designed by the difference of the cross-sectional area of the piston and the resilience of the spring to drive the suction stroke of different pistons. The compression pressure and volume change of the piston are generated when the compression of the gas is generated and the spring is restored. In this way, a large piston rapidly pumps air, resulting low voltage, and the internal negative pressure environment withintermediate vacuum level of a small piston is achieved. A micro fixed piston and a matched one-way valve are used to force the exhaust to increase the vacuum level. When the above device is used asthe container cover, the vacuum container can be used for collecting. Or an extension tube is added. The hand-pressing vacuum device can be connected with a general plastic bag and turns the general plastic bag into a vacuum storage, and is economical and convenient to realize vacuum storage of daily necessities.

Description

technical field [0001] The invention relates to a hand-held and portable press-type vacuum generating device, which adopts the synchronous working principle of three-layer cylinders with the same axis. The large piston in the outer layer generates large flow and rapid suction to form a low negative pressure vacuum, and the small piston generates a low-flow medium negative pressure. The design of vacuum pressure and forced exhaust of miniature fixed piston to enhance the high vacuum degree overcomes the physical characteristics of high expansion of gas in a negative pressure environment. And the application of multiple collocations makes it a vacuum storage storage application suitable for the use of various types of container top covers. Background technique [0002] Such as Figure 35 , the existing commercially available hand-pulled one-way pump must pull the piston quickly and frequently, which is inconvenient to use and has poor vacuum suction performance and vacuum degr...
