Abstract

The utility model discloses a water flow regulator and belongs to the field of instrument regulation. According to the water flow regulator, a T-junction is arranged in a box body and respectively connected with a water outlet pipe, a cold water pipe and a hot water pipe; a valve is mounted on the cold water pipe; another valve is mounted on the hot water pipe; a temperature sensor is mounted on the water outlet pipe; an LED display screen and key-presses are arranged on the box body; a singlechip is arranged in the LED display screen. Water flow enters the water outlet pipe, and the temperature of the water flow is measured by the temperature sensor and displayed on the LED display screen. According to the display temperature, a user can respectively regulate hot water flow and cold water flow via the key-presses to reach a proper bathing temperature. The water flow regulator is simple, easy and quickly to regulate, is visible, can prevent that over cold or over heat water causes the user's body uncomfortable, and can feed constant-temperature water to bathing tanks, bathing pools, swimming pools and the like. Moreover, the water flow regulator can supply constant-temperature water to clothe washing, rinsing and the like for families, can be used in public places, and is lower in cost and easy to generalize.

Description

A water flow regulating device

technical field

The utility model relates to a water flow regulating device, which belongs to the field of instrument control.

Background technique

In some current bathing centers, hotels, and families, the bathing control switches are mostly manually adjusted, which is relatively slow and does not contain a temperature display device, and the user may be exposed to overcooling or overheating at the beginning of adjustment. Hot water brings discomfort to the body of the bather. Although there is an automatic constant temperature electric water heater on the market, its price is too high and its use is relatively single, which cannot meet the needs of the public. During family laundry and washing in winter, the temperature adjustment of the water flowing out from the electric water heater is inconvenient or needs to be heated or cold water before use, which brings inconvenience to the user.

Contents of the invention

The purpose of the utility model is to provide a water flow regulating device with a temperature display, which can adjust the size and temperature of the water flow through buttons.

technical solution

The utility model comprises a box body, and a three-way is arranged in the box body, and the three-way connection is respectively connected to a water pipe, a cold water pipe, and a hot water pipe. Valves are installed on the cold water pipe, and valves are respectively installed on the hot water pipe. The motor is connected, the valve is connected with the stepping motor, and the outlet pipe is equipped with a temperature sensor; there are LED display screens and buttons on the box, and a single-chip microcomputer is installed in the LED display screen, and the temperature sensor, buttons, stepping motor, and stepping motor are respectively connected to the MCU connection.

The utility model is equipped with a temperature sensor, which can send a signal to the single-chip microcomputer through the button, transmit it to the stepping motor, and adjust the water flow and temperature at the same time. Users can adjust the appropriate temperature and water flow according to their own needs, which can prevent the user from being uncomfortable due to excessive cold or hot water.

Features of the utility model:

1. The utility model of the present invention is equipped with a temperature sensor on the water outlet pipe, which can transmit the water temperature in the water outlet pipe to the LED display screen, which is convenient for users to adjust the temperature.

2. The utility device of the present invention is equipped with stepping motors on the cold water pipe and the hot water pipe respectively, which can simultaneously adjust the size of the cold and hot water flow. It can be used to deliver constant temperature water to bathtubs, baths, swimming pools, etc. In winter, it can provide constant temperature water for family laundry, washing, etc., and can also be used for sinks in public places.

Detailed ways

The utility model is provided with a three-way in the box, and the three-way is respectively connected to the water pipe 1, the cold water pipe 5, and the hot water pipe 9, and the valve 4 is installed on the cold water pipe 5, and the valve 8 and the valve 8 are respectively installed on the hot water pipe 9. Connected with the stepper motor 10, the valve 4 is connected with the stepper motor 6, the outlet pipe 1 is equipped with a temperature sensor 7; the box is provided with an LED display 2 and buttons 3, and the LED display 2 is provided with a single-chip microcomputer and a temperature sensor 7 , button 3, stepping motor 6, and stepping motor 10 are connected with single-chip microcomputer respectively.

When in use: the outlet pipe 1, cold water pipe 5, and hot water pipe 9 in the box are connected to the outlet pipe, cold water pipe, and hot water pipe on the water heater, and then the power is turned on. There are two on the LED display 2 device. Button 3, one button is used to adjust the water volume, and the other button is used to adjust the temperature. According to the temperature on the LED display screen 2, the user sends a signal to the single-chip microcomputer through the button 3, and transmits it to the stepping motor 10 to adjust the size and temperature of the water flow. When bathing, fine-tuning can also be carried out by button 3 to reach the optimum temperature and water flow. For the same user, you only need to remember the appropriate button, and when you use it again, restore the last button to get the appropriate water temperature and water flow. This device can also be adjusted by button 3 to deliver quantitative constant-temperature water to bathtubs, bathing pools, swimming pools, etc.
