Waterflow pressure control switch

Abstract

The invention discloses a waterflow pressure control switch. The waterflow pressure control switch is characterized by including a base; the left side and the right side of the base are provided with a water inlet and a water outlet respectively; a first drumhead is arranged in the base and connection with a fixing ring underneath the first drumhead; a micro-touch switch button is arranged underneath the fixing ring, and the lower end of the micro-touch switch button is connected with a micro-touch switch; a second drumhead is arranged above the first drumhead and provided with an inner ring; the upper surface of the inner ring is provided with a sealing member, and one end of the sealing member is connected with one end of an iron core; the lower end of the iron core is connected with the inner ring through a volute spring, the iron core is arranged in a hollow bracket, and the upper end of the iron core is connected with the top of the hollow bracket through a spring; the outer side of the hollow bracket is sleeved with an electromagnet; a first port in one end of the electromagnet is connected with a second port underneath the micro-touch switch through a power circuit. The waterflow pressure control switch has the advantages of being simple in structure, safe, effective, high in sensitivity and the like.

Description

technical field [0001] The invention relates to a switch, in particular to a water flow pressure control switch, which can effectively cut off the water and power of the water purification equipment. Background technique [0002] The micro switch is a contact mechanism with a small contact interval and a quick action mechanism, which performs switching action with a specified stroke and a specified force. It is covered with a shell and has a drive rod outside. It is relatively small, so it is called micro switch, also known as sensitive switch. [0003] Electromagnetic relay is an electronic control device, which has a control system (also known as input circuit) and a controlled system (also known as output circuit), usually used in automatic control circuits, it actually uses a smaller current, lower An "automatic switch" that controls a larger current and a higher voltage with a higher voltage. Therefore, it plays the role of automatic adjustment, safety protection, and...
