When the resident takes water, the resident presses the driving button after swiping a card or inserting coins, the lifting door descends and opens, the resident inserts the water bucket opening downwards into the slot 102, the equipment washes the inner wall of the water bucket firstly, then the resident inverts the water bucket to enable the water bucket opening to be upwards, then presses the water selling button, and the purified water outlet above the water receiving bin 101 starts to drain until the water bucket is full. After the resident finishes taking water, the end button is pressed, and the lifting door is lifted to be closed, so that one water taking action is completed.
It should be noted that, through market research, the use environment of some resident's home casks is relatively poor, for example the cask is placed on kitchen or balcony for a long time, and oil smoke or dust pollute the cask inner wall easily to pollute the quality of water in the cask, so this equipment can wash in the cask before every turn intaking.
As shown in fig. 2,3 and 4, an RO membrane filter 2, a pure water tank 3 and a concentrate tank 4 are arranged in the shell 1, pure water filtered by the RO membrane filter 2 is stored in the pure water tank 3, a water taking unit directly absorbs pure water from the pure water tank 3 and discharges the pure water through a pure water outlet, concentrate water generated when the RO membrane filter 2 works is stored in the concentrate tank 4, water for flushing the inner wall of a bucket is from the concentrate tank 4, a concentrate pipe 5 is communicated with a concentrate outlet of the RO membrane filter 2, the tail end of the concentrate pipe 5 is communicated with a first drain pipe 7 and a second drain pipe 8 through a first water valve 6, the first drain pipe 7 is communicated with the concentrate tank 4, and the second drain pipe 8 is communicated with an external sewer pipe.

The front end of the RO membrane filter 2 is also provided with an activated carbon filter, a PP cotton filter and a booster pump, and the water pressure entering the RO membrane filter 2 is improved after the tap water is preliminarily filtered.
It should be noted that, fig. 2 is only a schematic water path diagram of the present apparatus, and how each pipeline is specifically arranged needs to be designed according to the actual situation of the apparatus. In the water selling process, pure water generated by the RO membrane filter 2 enters the pure water tank 3 through the pure water pipe 9 and is absorbed by the water taking unit from the pure water tank 3 synchronously through the pure water pump 10, concentrated water generated by the RO membrane filter 2 enters the first water discharging pipe 7 through the first water valve 6 and finally enters the concentrated water tank 4 through the concentrated water pipe 5, when maintenance personnel periodically maintain equipment, the equipment is kept in a water making state (namely, external tap water is not supplied to the equipment), the pure water pump 10 is turned on, the pure water pump 10 reversely absorbs water, namely, pure water in the pure water tank 3 flows back to the inside of the RO membrane filter 2 through the pure water pipe 9, back flushing is carried out on the RO membrane (the back flushing water pressure is not more than 0.2MPa, so that the RO membrane is prevented from being damaged, the back flushing time is not more than 15 s), impurities attached on the RO membrane are separated from the RO membrane, and the RO membrane is carried out of the RO membrane filter 2 by the water flow.

Note that the second water valve 1206 is an electronically controlled three-way valve or a manual three-way valve. When maintenance personnel regularly maintain the equipment, the second water valve 1206 is adjusted, the flushing water pump 1204 is started after the adjustment, pure water in the pure water tank 3 enters the flushing water pipe 1205 after passing through the second water suction pipe 1208 and passing through the second water valve 1206, and is sprayed out through the flushing head 1202 to flush a pure water outlet at the top of the water sump 101, and after flushing is finished, the second water valve 1206 is adjusted to be in an initial state. In summary, the flushing unit 12 in this embodiment can not only suck the concentrated water to flush the water tub, but also suck the pure water to flush the pure water outlet.
Example 2
When in actual use, maintenance personnel need to adjust the state of the first water valve 6 before back flushing the RO membrane filter 2, and the state of the first water valve 6 needs to be adjusted after back flushing is finished. The operation is more complicated, and if the maintenance personnel forgets to adjust back the state of the first water valve 6, the later concentrated water is always discharged through the second water discharge pipe 8 and cannot enter the concentrated water tank 4.

Under the condition that pure water is stored in the pure water tank 3, the foam blocks 18 always float on the water surface, so that the lower surface of the arc-shaped baffle 17 is always positioned about 1mm below the water surface. Thus, in the back flushing process of maintenance personnel, the arc-shaped baffle 17 plays a role in sealing a part of the vertical groove 901, so that the pure water pipe 9 can absorb water from the pure water tank 3, and a small amount of air above the water surface is mixed in the water to be sucked into the pure water pipe 9 together due to the fact that the lower surface of the arc-shaped baffle 17 is close to the water surface, and the air is mixed with the water in the pure water pipe 9 to form small bubbles. Pure water mixed with small bubbles enters the RO membrane filter 2, the bubbles are broken after contacting with the RO membrane, vibration is generated, impurities attached to the RO membrane are promoted to be separated from the RO membrane, and the backwashing effect is improved.
Example 4

In the state of fig. 10, the semicircular plate 13 does not hinder pure water, and pure water can smoothly flow to the pure water tank 3.
Note that, the semicircular plate 13 in the state of fig. 10 is not completely parallel to the direction of the water flow, but forms a certain angle with the direction of the water flow, so that, when back flushing is performed next time, pure water flowing from bottom to top can act on the semicircular plate 13 and push the semicircular plate 13 to rotate counterclockwise to the state shown in fig. 8. In addition, in order to ensure that the second protruding strips 20 can drive the rotating shaft 605 to rotate, 2-3 groups of second protruding strips 20 and the bearing plate 21 can be arranged on the semicircular plate 13 along the circumferential direction of the rotating shaft 605. And a rubber strip is arranged between the second raised strip 20 and the semicircular plate 13, the rubber strip is in a compressed state, when the water flow does not act on the bearing plate 21 to generate a force towards the inside of the rotating shaft 605, the rebound of the rubber strip can promote the separation of the second raised strip 20 from the groove on the surface of the rotating shaft 605, and further, the surface of the second raised strip 20 towards the rotating shaft 605 can be designed into an arc shape to further promote the separation of the second raised strip 20 from the groove on the surface of the rotating shaft 605.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the invention, which is defined by the appended claims.
