One-way valve and cooking machine using the same

Abstract

The invention relates to a one-way valve and a food processer using the one-way valve. The one-way valve comprises a valve body, a valve element, a valve bonnet, a valve rod, a pressure spring and a snap spring; the valve element comprises a valve rod channel located in the center and a liquid passing hole, a liquid inlet pipe is arranged at the lower end of the valve body, and a liquid guide hole is formed in the intersecting position of the liquid inlet pipe and the valve body; a valve element cavity is formed in the upper opening end of the valve body, and the valve element is fixed into the valve element cavity to be connected with the valve body; the valve bonnet is embedded on an annular clamping groove of an extending-out part of the valve rod through the snap spring in manners that the valve rod penetrates the valve element, and the pressure spring is installed on the extending-out part of the valve rod; and the bottom face of the valve bonnet and the upper end face of the valve element are attached to achieve liquid sealing. The one-way valve further comprises a valve stopping ball and a valve stopping base, the valve stopping base is provided with a liquid inlet through hole and arranged in a valve body cavity, the liquid inlet through hole is communicated with the liquid guide hole in a butt joint manner, and the valve stopping ball is arranged at the top of the liquid inlet through hole of the valve stopping base in a fit manner so as to achieve liquid sealing. The food processer using the one-way valve has the beneficial effects of preventing the liquid passing hole of the one-way valve from being blocked by foods, enabling the valve bonnet to be opened when forcing hot water is injected, and enabling the valve bonnet to be automatically closed when no hot water flows.

Description

technical field [0001] The invention relates to a device for cooking machines, in particular to a one-way valve.
