WATER PURIFIER EUROPOLO-GROUP CO.LTD.

Working principle and composition of dual water vending machine:

1. Working principle

The working principle of dual water vending machine mainly revolves around water purification and water vending service, which includes the following steps:

Water purification:

Tap water enters the water vending machine through water pump pressurization or tap water pressure.

It is purified through multiple filters, which may include activated carbon filters, PP cotton filter elements, RO membranes, etc. to remove impurities, odors, bacteria, etc. in the water.

The purified water is stored in the water tank, waiting for users to take water.

Water vending service:

Users pay by inductive IC card, coin or code scanning.

After receiving the payment signal, the water vending machine control system controls the water outlet switch to open.

Users select the water outlet (such as normal temperature water outlet or hot water outlet) according to their needs to obtain water of the required water quality.

2. Components

The components of the dual-water vending machine mainly include the following systems:

Water purification system:

Including pre-treatment filter element, core water purification device (such as RO membrane), post-filter element, etc., used for multi-stage filtration and purification of tap water.

Water vending system:

Including water outlet switch, inductive IC card reader, coin machine, barcode scanner, etc., used to receive user payment and control water outlet.

It also includes a water tank for storing purified water.

Power supply system:

Provides power support for the water vending machine, usually using 220V electric drive technology, and the water purification and water vending systems use lower voltage to ensure safety.

Control system:

It is called the "heart" of the water vending machine, mainly composed of water vending control motherboard, water purification controller, coin machine, card reader, power supply, etc.

Responsible for monitoring the overall operation status of the water vending machine, including water quality monitoring, pressure monitoring, voltage monitoring, etc.

Other auxiliary systems:

Cleaning and disinfection system: such as automatic ozone sterilization and ultraviolet sterilization devices, used to ensure the cleanliness of water tanks and pipes.

Antifreeze and insulation system: For outdoor water vending machines, automatic temperature control sensing devices and insulation materials are used to ensure normal operation in winter.

In addition, dual-water vending machines may also have some special designs, such as dual faucets (providing normal temperature water and hot water respectively), smart display screens (displaying water quality information, payment amount, etc.), seats and placement slots (convenient for users to place water bottles), etc.

In summary, dual-water vending machines provide users with convenient, safe and economical ways to get water through complex water purification and water vending service systems. Its components include water purification systems, water vending systems, power supply systems, control systems and other auxiliary systems, 

which together ensure the normal operation of water vending machines and meet user needs.
