When the person of expense completes water intaking, " warm water/stopping " or " cold water/stopping " virtual push button is again tapped on, is controlled often by central processing unit 5
Warm outlet valve or cold water outlet valve are closed.
When consumer takes hot water, " hot water/stopping " virtual push button is clicked, Locked Confirmation region 62 is discharged at this time and starts work
Make, the prompt information such as " cup, Caution! Hot please be put " is shown on character showing area and shows the confirmation for releasing hot water effluent
Key, consumer need to click confirmation key, could continue hot water water intaking, control hot water effluent's valve by central processing unit 5 at this time
It opens；When consumer completes to fetch water, " hot water/stopping " virtual push button is again tapped on, hot water effluent is controlled by central processing unit 5
Valve is closed.In the operating process of above-mentioned confirmation key, pressing confirmation key just opens hot water effluent within the defined time (5 seconds)
Valve hides all keys when exceeding schedule time after (20 seconds) after water outlet again without key operation signal automatically, and water dispenser is replied
Standby or multimedia state, with prevent children arbitrarily disorderly press the water outlet of hot water key be burned or when cup is not put well out hot water and
Sputtering scald.
Consumption mode is flow (i.e. to be upgraded to unit) charging；Its reimbursement of expense mode can by " wechat ", " Alipay ",
" the day wing ", " movement " or the payment of other payment platforms.It needs supplement with money just if consumer's remaining sum (shared drinking-water account) is insufficient
Next-step operation can be carried out, the account balance of consumer is shown after supplementing with money.In the case where consumer account's surplus, consumer
Room temperature button, hot water button or cold water button are clicked as needed, then water purification (palpus when hot water taking of faucet outflow relevant temperature
Could be discharged after releasing child lock), while can put and hit a glass button and take cup, if the included water bottle of consumer, can skip the step
Suddenly.Automatic charging during water intaking, charging are more than that then water dispenser is automatically stopped water outlet to account balance, and consumer is moving after having fetched water
Payment is completed in dynamic terminal；If Sorry, your ticket has not enough value by consumer account, prompt is supplemented with money.
Each shared direct drinking fountain is communicated with each other by cloud server and service terminal and mobile client, is implemented to main body
Water source, water quality, state of runtime machine, cup cylinder etc. are supervised and are reported and submitted, and management service personnel pass through the service that connect with Cloud Server
Terminal can control the operation conditions of each direct drinking fountain whenever and wherever possible.In the direct drinking fountain course of work, encounter failure can in time to
Maintenance personnel pushes dependent failure data, and the personnel of maintaining easily safeguard, so that it is guaranteed that direct drinking fountain operates normally.
The utility model is different from the water dispenser of tradition machinery formula key, joined on direct drinking fountain shell for showing
The multimedia display screen of virtual key solves the problems, such as that mechanical key service life is shorter, while hot water locking function is added
Can, avoid child play or machine clean when accidentally by hot water key flow out hot water and scald.
The above, the only preferred embodiment of the utility model, the utility model are not limited to above-mentioned implementation
Mode, as long as its technical effect for reaching the utility model with identical means, all should belong to the protection scope of the utility model.
