High flow speed and low flow resistance self-power-generation type sensing faucet with pressure stabilizing structure

Abstract

The invention provides a high flow speed and low flow resistance self-power-generation type sensing faucet with a pressure stabilizing structure. The faucet is mainly composed of a solenoid valve (2), a water flow power generation device (4), a pressure stabilizing valve (5) and a sensing device. An inlet of the solenoid valve (2) is connected with an inlet of a tap water pipe, an outlet of the solenoid valve (2) is connected to an outlet (6) of the tap water pipe through the water flow power generation device (4) and the pressure stabilizing valve (5) via branch passages, the sending device controls the solenoid valve (2) through a signal of the sensor, and opening and closing of the faucet are achieved. The high flow speed and low flow resistance self-power-generation type sensing faucet can well solve the problems that the flow resistance is too large and the power generation efficiency is too low in the prior art. Furthermore, energy of tap water is reasonably utilized to effectively generate power to be supplied to a sensing system, the overall flow resistance of the faucet is reduced, the flow velocity is improved, and the faucet is suitable for being used in the environment with low water pressure.

Description

technical field [0001] The invention relates to a self-generating induction faucet, in particular to an energy-saving induction faucet which utilizes water flow to generate electricity and reduces flow resistance through a voltage stabilizing structure to achieve a higher flow rate. Background technique [0002] Nowadays, the faucet is an essential basic facility for every household and office, but the secondary pollution of the faucet in the bathroom troubles the users. In order to solve the problem of secondary pollution, induction faucets are usually used. However, this kind of faucet needs power supply, and the power supply method is divided into three categories: 1. Use 220V AC power supply, and use voltage conversion as the faucet power supply. Due to the humid environment, there are potential safety hazards and additional wiring problems; 2. Use Battery power supply avoids the problem of line laying, but there are problems of battery replacement and maintenance; thir...

Problems solved by technology

[0003] However, the traditional self-generation system allows all the water to flow through the power generation structure, causing problems such as excessive flow resistance and too low flow velocity.

[0004] At the same time, the traditional self-generating structure causes the power generation to exceed the requirement, and the energy loss of the water flow is too much, which indirectly consumes the energy used for pressurization by the water company. In addition, in an environment with low water pressure, it is easy to cause insufficient water output and cannot be used normally.
