Embodiment 1

[0029] Such as Figure 1 to Figure 10As shown, a new single-contact water pressure switch includes a seat body, the seat body includes an upper cover 1 and a lower cover 2, and a water pressure detection mechanism and a contact switch are arranged in the seat body. The lower cover 2 is provided with a diaphragm accommodation cavity 11 with an opening facing the upper cover 1 , and a fluid passage 12 communicating with the lower cover 2 is provided in the middle of the diaphragm accommodation chamber 11 . A diaphragm 3 is installed in the diaphragm accommodation chamber 11, a pressure plate 4 is arranged above the diaphragm 3, a through hole 5 is arranged in the middle of the pressure plate 4, a push rod 6 is arranged above the pressure plate 4, and the bottom end of the push rod 6 passes through the through hole. The hole 5 is in contact with the upper end surface of the diaphragm 3 . The push rod 6 includes a basic push rod section 7, an intermediate push rod section 37 and ...

Abstract

The invention provides a novel single-contact water pressure switch, belongs to the technical field of water pressure detection, and aims at solving the problem that a water pressure switch in the prior art is relatively larger in overall structure and cannot meet the requirements for intelligent and miniaturized development of household appliances. The novel single-contact water pressure switch comprises a base body which comprises an upper cover and a lower cover, a water pressure detection mechanism and a contact switch mechanism are arranged in the seat body, the water pressure detection mechanism comprises a push rod assembly driving rod which moves between the upper cover and the lower cover, and the driving rod is arranged on a path on which the push rod assembly moves up and down. The driving rod transversely rotates under the thrust action of the push rod assembly so as to push the contact switch to act, so that the driving rod does not need to move in the moving direction of the push rod assembly, the space required by the action of the internal switch of a product is saved, and the height of the product is reduced; the base is used as an installation base of a contact switch mechanism, so that the number of product parts and required molds is reduced, and the product volume is reduced.

Description

technical field [0001] The invention belongs to the technical field of water pressure detection, and in particular relates to a novel single-contact water pressure switch. Background technique [0002] The water pressure switch is usually sealed with a diaphragm, and the driving plate is pushed through the deformation of the diaphragm to make the micro switch on and off. The driving path of the driving plate in the prior art is generally in the same direction as the path of the diaphragm deformation, that is, the longitudinal direction. The setting makes the product height relatively high, so the product is larger overall. At present, home appliances are gradually developing towards intelligence and miniaturization, so the conventional structure cannot meet this requirement. Contents of the invention [0003] The present invention proposes a new type of single-contact water pressure switch, aiming at that the overall structure of the water pressure switch in the prior art...
