Portable vacuum cup with manual extraction function without power supply

Abstract

The invention discloses a portable vacuum cup with a manual extraction function without a power supply. The portable vacuum cup comprises an upper cup body, an output base and a lower cup body; a valve body assembly and a pressurizing assembly are connected between the upper cup body and the output base; the pressurizing assembly is used for pressing water in the upper cup body into the output base through the valve body assembly; the pressurizing assembly comprises a pressurizing base, a compression cylinder arranged on the pressurizing base and a power assisting piece rotationally arranged between the upper cup body and the pressurizing base; a piston rod is arranged in compression cylinder, the end of the piston rod is hinged to the power assisting piece. The end part of the compressioncylinder is eccentrically hinged to the pressurizing base; a water inlet and a water outlet are formed in the end parts of the compression cylinder; when the power assisting piece is rotated, a transmission part and the piston rod simultaneously drive the compression cylinder to rotate, and the relative distance between the transmission part and the compression cylinder is increased or decreased,so that the piston rod moves in the compression cylinder, a force arm between a stress point and a force application point on the piston rod is greatly increased, and the operation is easy and labor-saving.

Description

technical field [0001] The invention relates to the technical field of coffee machines, in particular to a portable thermos cup with the function of manual extraction without power supply. Background technique [0002] Coffee as a drink has been widely popularized in social occasions and office crowds. Brewed coffee on the market is ground into coffee powder and packaged in small cups or bags, such as coffee pods and coffee capsules, which greatly simplifies the The process of brewing coffee. At present, there is a portable coffee machine on the market, which is used to brew coffee conveniently when going out or driving a car. This kind of portable coffee machine is manually squeezed and pulled Air pressure is generated, and hot water is pressed into the coffee bag / capsule through the air pressure, so as to extract the coffee. In this process, the internal atmospheric pressure needs to be overcome, repeated operations are laborious, and the hands are prone to fatigue. A port...

[0002] Coffee as a drink has been widely popularized in social occasions and office crowds. Brewed coffee on the market is ground into coffee powder and packaged in small cups or bags, such as coffee pods and coffee capsules, which greatly simplifies the The process of brewing coffee. At present, there is a portable coffee machine on the market, which is used to brew coffee conveniently when going out or driving a car. This kind of portable coffee machine is manually squeezed and pulled Air pressure is generated, and hot water is pressed into the coffee bag / capsule through the air pressure, so as to extract the coffee. In this process, the internal atmospheric pressure needs to be overcome, repeated operations are laborious, and the hands are prone to fatigue. A portable coffee machine in the prior art The coffee machine resets the piston rod by adding a spring, and the belt also receives the resistance of the spring when it is pressed, and there is also the influence of the elastic fatigue of the spring, and the filter effect of the portable coffee machine in the prior art on the coffee bag Not good, there are still fine particles in the filtered coffee, which leads to poor coffee taste, and it is necessary to set up another cup to accept the coffee, which will cause both a coffee machine and a travel mug to be used, which is too inconvenient to use
