Smart home water inlet control valve

Abstract

The invention discloses an intelligent household water inlet control valve. The existing water valve cannot manage and control unattended accidental water overflow. The invention is installed in the general water inlet pipe of the family, and includes a power supply management module, a signal acquisition module, an input and output module, an execution module and a control module. Collect water flow information through the signal acquisition module, use the microprocessor to calculate the duration of the current single water flow and compare it with the maximum duration of the set single water flow, so as to judge whether the current water flow of the household water inlet pipe is caused by normal water use or unattended caused by accidental flooding. If it is judged to be an accidental overflow event, the microprocessor sends a signal to close the solenoid valve for normally open water through the execution module to close the water inlet of the user's main water inlet pipe, thereby achieving the effect of cutting out the accidental overflow event, and at the same time an alarm is issued to notify the user. The device of the invention has the advantages of simple structure, low power consumption, convenient use, and can effectively prevent the occurrence of accidental water overflow events.

Description

technical field [0001] The invention belongs to the technical field of water valves, in particular to an intelligent household water inlet control valve. Background technique [0002] In recent years, with the improvement of people's awareness of environmental pollution and the difficulty of drinking water in some cities during the summer peak period due to the decline of groundwater levels, the awareness of water conservation has generally increased among the people. How to minimize the loss and waste of tap water for residents has become the focus of everyone's attention. There are various water-saving faucets currently on the market, and their working principles are mainly divided into three categories: a) Flow-limiting and water-saving, that is, flow-limiting to reduce water loss in the process of using water. b) Shorten the opening and closing time of the faucet, and reduce the waste of water in the process of switching. c) Ceramic seal reduces dripping. The above thr...

Problems solved by technology

The above three water-saving methods have obvious effects. To a certain extent, they solve the water-saving during regular water use, but they cannot reduce the waste caused by accidental overflows such as forgetting to turn off the tap or bursting water pipes.

According to the survey, most solar water heater users forget to close the sluice gate when they fill up the water, ranging from a few minutes to a few hours, or forgetting that the roof has been closed for several days. In the case of water heaters overflowing, this not only causes great losses to users, but also is a great waste of precious water resources

In addition, family water pipe bursts and other situations also occur from time to time. If no one is at home, the consequences not only waste our source of life, but also cause serious consequences of flooding our own home and even neighbors.
