Abstract

The invention discloses a pressure switch device, a vacuum pumping device, a stirring cup assembly and a food processor, wherein the pressure switch device comprises a casing assembly, a pressure relief assembly and a pressure switch assembly; the casing assembly comprises a first casing and a second casing in sealed connection; a pressure relief cavity and a pressure measuring cavity which communicate with each other are defined by the first casing and the second casing; the cavity wall of the pressure relief cavity is provided with a pressure relief opening communicating with the pressure relief cavity; the pressure relief assembly is arranged in the pressure relief cavity; the pressure relief assembly comprises a valve body push button capable of sealing and blocking or opening the pressure relief opening; the pressure switch assembly is arranged in the pressure measuring cavity; and an air pressure connector communicating with an external container is arranged on the first casing or the second casing, and communicates with the pressure relief cavity and the pressure measuring cavity. The technical scheme has the advantages that the pressure relief assembly and the pressure switch assembly are combined together; only one air pressure connector is arranged; the air pressure connector communicates with the pressure relief cavity and the pressure measuring cavity, so that the number of the connector can be reduced; and the air leakage probability is reduced.

Description

technical field [0001] The invention relates to the technical field of pressure switches and pressure relief valves, in particular to a pressure switch device, a vacuum device using the pressure switch device, a stirring cup assembly using the pressure switch device, and a vacuum device or a stirring cup assembly using the pressure switch device food processor. Background technique [0002] Existing household appliances with a vacuum function, such as vacuum devices for food processors, use two independent components, namely a pressure switch and a pressure relief valve, in order to simultaneously realize the pressure on-off control and pressure relief function. , respectively communicated with the vacuum container or connected with an independent air duct to realize the function. However, this connection method leads to a large number of parts, complicated assembly, and many interfaces, resulting in a high probability of air leakage. Contents of the invention [0003] T...
