Content Description

The utility model relates to the field of water meters, in particular to a multifunctional intelligent water meter.

Background of the invention

At present, there are various types of water meters in the society, and smart water meters are high-tech products that have been developed in recent years based on automatic control technology and information network technology, relying on information management requirements, and are currently in the water sector due to water pipes. The aging of the network and the destruction of external forces, or the destruction of pipeline connection water devices, and forgetting to close the water valve and other leaking conditions are common, and the general water meter has only measurement function, no leak detection function.

Summary of the Invention

In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a simple, environmental-friendly multifunctional smart water meter with a leak detection function.

The technical solution adopted by the utility model to solve its technical problems is: a multi-function intelligent water meter including a water meter housing; wherein: the water meter housing has an intelligent digital display at one end of the cover, and a base dial guard at the other end. There is a character wheel in the base dial cover; the water meter has a controller inside, and the controller is connected with the intelligent digital display, power supply module, transformer, leak detection module and wireless module The said controller is also provided with a controller shield, the water meter outlet is equipped with a solenoid valve and a temperature sensor; the temperature sensor is connected with the controller.

The figure shows the structure of the utility model

The working principle of the invention is that when the water flow through the water meter, the word wheel rotates to record the water consumption, the water flows to the outlet of the water meter, the temperature sensor detects the temperature of the water, and the water consumption and the temperature are sent to the intelligent digital display through the controller. The leak detection module has a pressure sensor, an initialization unit and a blocking mechanism; the pressure sensor and the blocking mechanism are respectively connected with the alarm module; the pressure sensor is installed at the lower end of the water meter and is connected with the initialization unit; when in use, the initialization unit is Set the pressure sensor to collect data for a long time. Once it reaches the length, it will start the alarm module to alarm. When there is water flowing through the water meter, the pressure sensor will be timed by the effect of water gravity. If the user forgets to turn off the water or the water pipe leaks, the water meter Continuous flow of water flows through the gravity sensor. Once the initial setting time is exceeded, an alarm is issued to remind the user to check. The blocking mechanism has a button and a return spring. Once a person needs water for a long time, only the resistance on the water meter is required to stop. Break the button in the body and disconnect the gravity Is connected to the alarm module; button up when the return spring, the gravity sensor and the leak alarm module connection start again.

As a further improvement of the present invention, the leak detection module has a pressure sensor, an initialization unit and a blocking mechanism; the pressure sensor and the blocking mechanism are respectively connected with an alarm module; and the pressure sensor is installed at the lower end of the internal water meter. And connect with the initialization unit. The alarm module is a buzzer, a strobe light or a combination of both. The power module is a button lithium battery. The base dial shield is made of tempered glass. The wireless module is connected to the mobile terminal through wifi or bluetooth. The mobile terminal is a smart phone or a computer.

Compared with the prior art, the utility model has the beneficial effects that: the utility model has a metering water consumption, a water temperature and a leak detection function; the leak detection function can effectively reduce the waste of water resources, and uses the gravity sensing principle of water itself. , Energy-saving and convenient.
