As shown in Fig. 1-Fig. 7, the drinking device 100 according to the utility model embodiment substantially may include: shell 10, Water tank 20 and smart seat 50.

Specifically, as shown in Figure 1,10 roof of shell has installing port 11.Water tank 20 is located in shell 10, and water tank 20 has There are venthole 211, air inlet 221, apopore 231 and water outlet 24, venthole 211 and air inlet 221 are each provided on water tank 20 Portion, venthole 211 are suitable for connection exterior space.

Smart seat 50 is located on shell 10, and smart seat 50 top open wide, and smart seat 50 top week along with installation The inner edge of mouth 11 seals cooperation, to avoid the water in soft water bag 200 all edges and 11 inner circumferential of installing port at the top of smart seat 50 Flowed out in gap between, sealing ring 43 can be equipped between all edges in the top of smart seat 50 and 11 inner edge of installing port, with into One step improves airtightness and then improves safety, wherein can connect water source on smart seat 50, water source can for hard bucket, Soft water bag 200 etc., in the present embodiment for connecting soft water bag 200 on smart seat 50.

Further, smart seat 50 has first interface 51 and second interface 52, and second interface 52 can be located at smart seat 50 bottom, for example, example as shown in Figure 7, the height of second interface 52 in the vertical direction is not less than apopore 231, this Outside, it is connected between first interface 51 and air inlet 221 by air inlet pipe, passes through water outlet between second interface 52 and apopore 231 Pipe is connected, meanwhile, it is connected between air inlet pipe and outlet pipe by connecting tube.

It is understood that as the water in soft water bag 200 is constantly reduced, in the hydraulic pressure in soft water bag 200 and water tank 20 The pressure difference of air pressure also constantly change, according to the continuous variation of the air pressure in the hydraulic pressure and water tank 20 in soft water bag 200 Pressure difference, the course of work of the drinking device 100 in the application can substantially be divided into three phases:

The T1 stage: since water level pressure difference is high in soft water bag 200 and water tank 20, the water in water bag 200 is by smart seat 50 Flowed through after first interface 51 air inlet pipe, water tank 20 air inlet 221 into water tank 20 plus water, also, the water in water bag 200 can also The apopore 231 of outlet pipe, water tank 20 is flowed through after the second interface 52 of smart seat 50 into water tank 20 plus water, in water tank 20 Water level rises, and air is extruded, and the air in water tank 20 all passes through the open to atmosphere venthole 211 of connection and is discharged.

The T2 stage: when 100 normal use of drinking device, the water in soft water bag 200 can slowly tail off, soft water bag 200 with Pressure difference in water tank 20 also becomes smaller gradually, when pressure difference between the two is close to critical value, i.e., close to the T2 stage when, smart seat 50 First interface 51 and water tank 20 air inlet 221 between just no longer have water and flow through, that is to say, that have water in air inlet pipe Column, the pressure at water column both ends keep balance, at this point, water mainly pass through the outlet pipe of connection second interface 52 and apopore 231 to Moisturizing in water tank 20.Water level rises in water tank 20, and air is extruded, and the air in water tank 20 all passes through the open to atmosphere venthole of connection 211 discharges.

The T3 stage: the pressure when the water in soft water bag 200 there remains close to the T3 stage, in soft water bag 200 and water tank 20 There is negative pressure, i.e., the pressure that water column is located at 221 side of air inlet in air inlet pipe is greater than the pressure positioned at 51 side of first interface, this When, the water column part in air inlet pipe can enter outlet pipe discharge by communicating pipe under pressure, and part then passes through air inlet Pipe flows into soft water bag 200, and the water in air inlet pipe is emptied, so that air can enter soft water bag 200 by air inlet pipe It is interior so that the pressure in soft water bag 200 restores, water flow can be continued to flow by outlet pipe in water tank 20 (i.e. again under Water).

When the lower water flow of water flow is excessive, at this point, water flow can reenter in water inlet pipe, and water inlet pipe is blocked, At this moment, it continues through outlet pipe and adds water into water tank 20, the pressure in soft water bag 200 and water tank 20 can be made to bear again Pressure, i.e., the pressure that water column is located at 221 side of air inlet in air inlet pipe are greater than the pressure positioned at 51 side of first interface, in this way, into Water column in tracheae empties again under pressure, so that air can be entered in soft water bag 200 again by air inlet pipe, Hereby it is achieved that water inlet-emptying-air inlet circulation in air inlet pipe, to realize discontinuity air inlet in soft water bag 200, and then realizing will Water in the soft water bag 200 connecting with smart seat 50 empties, and avoids water resource waste, improves utilization rate.
