To meet people to quality of life increasingly higher demands, technical staff have devised can be to being stored in drinking-water
Water in machine is heated the water dispenser even to freeze, so that user takes according to self-demand.
Reversed bay-type drinking-water switch is provided on water dispenser, user is according to the actual demand of oneself by opening and closing reversed bay-type drinking-water
It switchs to take the water stored in water dispenser.
A kind of reversed bay-type drinking-water switch, as shown in Figures 2 and 3, including water drinking tube 1, spool 2 and faucet 3, water drinking tube
1 lower end is equipped with water outlet 11, and one end of spool 2 stretches into water outlet 11, the other end be located at water outlet 11 outside and with faucet 3
Connection, spool 2 can be moved, be set successively from top to bottom between water outlet 11 and faucet 3 between the open and the closed positions
It is equipped with the first telescopic sealing set 41, connecting tube 5 and the second telescopic sealing set 42, the upper end of the first telescopic sealing set 41
It is tightly connected with water drinking tube 1, lower end is tightly connected with connecting tube 5, and upper end and the connecting tube 5 of the second telescopic sealing set 42 seal
Connection, lower end are tightly connected with faucet 3, and the inner wall of the first telescopic sealing set 41, the inner wall of connecting tube 5 and second can stretch
Water stream channel, and the exhalant canal 31 of water stream channel and faucet 3 are surrounded between the inner wall and the outer wall of spool 2 of contracting sealing shroud 42
Connection, when spool 2 is moved upward to open position, water drinking tube 1 is connected to water stream channel, and the first telescopic sealing covers 41 quilts
Faucet 3, which squeezes, to be shunk, and when spool 2 is moved downward to closed position, water drinking tube 1 is disconnected with water stream channel, and first can stretch
Contracting sealing shroud 41 restores to the original state, and water stream channel is made to generate suction.
Reversed bay-type drinking-water switch provided by the invention, when moving to open position on spool 2, reversed bay-type drinking-water switch is beaten
It opens, user directly can take water out of faucet 3.At this point, since faucet 3 moves up so that faucet 3 and connecting tube 5

The case where outflow so that the reliability of reversed bay-type drinking-water switch is high.Meanwhile reversed bay-type drinking-water provided in an embodiment of the present invention is opened
It closes due to there is no the mutual cooperation between plastic part, two scalable sealing shrouds need to only be connect with water drinking tube 1 and faucet 3 respectively
, therefore without considering the cooperation precision between component when production, to reduce production cost.And the present invention is due to using
The structure of two telescopic sealings sets and connecting tube 5, reversed bay-type drink water switch open when, each telescopic sealing set
Decrement is all little, is in contact with the outer wall of spool 2 to avoid the occurrence of its inner wall after telescopic sealing set is compressed, leads to water
The case where circulation road is blocked, and reversed bay-type drinking-water switch cannot be normally discharged.
To enable the first telescopic sealing set 41 and/or the second telescopic sealing set 42 convenient for compression, first is scalable
The barrel of sealing shroud 41 and/or the second telescopic sealing set 42 has variable-diameter structure.First telescopic sealing set 41 and/or second
When the barrel of telescopic sealing set 42 has variable-diameter structure, the first telescopic sealing set 41 and/or the second telescopic sealing set 42
When compressed, the position for deformation occur is the changed position of its diameter, keeps deformation controllable, and required power is smaller,
It is prone to deformation, to preferably play the role of back suction, is more advantageous to reversed bay-type drinking-water switch water outlet.
To make reversed bay-type drinking-water switch that can smoothly be discharged after opening, as shown in Figures 2 and 3, the internal diameter of connecting tube 5
It is identical as the diameter of water outlet 11.Flow is flowed out out of water drinking tube 1 through water outlet 11, into water stream channel, connecting tube 5
Inner wall be water stream channel a part, if the internal diameter of connecting tube 5 is identical as the diameter of water outlet 11, flow can be more suitable
Enter in the exhalant canal 31 in faucet 3 by water stream channel sharply.Flow is flowed from water outlet 11 after drinking-water switch is opened
Go out to enter in connecting tube 5, after flow is hit in connecting tube 5 with spool 2 on inner wall of the rebound to connecting tube 5, when connecting tube 5
When internal diameter is more than the diameter of water outlet 11, movement of the flow in connecting tube 5 is more acutely and irregular, flows to faucet 3
It is possible that the case where splashing will appear the possibility that user is burned, and even if user takes hot water at this time when flowing out afterwards
The internal diameter of take over 5 increases, and correspondingly can also increase the production cost of connecting tube 5, be unfavorable for cost control.If connecting tube 5 is interior
Diameter is less than the diameter of water outlet 11, and flow first can cover 41 after being flowed out in water outlet 11 in compressed first telescopic sealing
It is hoarded in inner space, so that telescopic sealing set 41 is generated deformation, this increases the first telescopic sealing set to a certain extent
41 working strength, if the hypervolia hoarded in the inner space of compressed first telescopic sealing set 41, it may appear that the
The decrement passive recovery of one telescopic sealing set 41 even struts the first telescopic sealing set 41, and drinking-water switch is caused to be closed
Negative pressure can not be generated in water stream channel afterwards so that the residual water outflow in water stream channel.
To keep the connection between two telescopic sealing sets and connecting tube 5 more stable, as shown in Figures 2 and 3, connecting tube
5 outer wall both ends are respectively set there are one annular recess, and one end insertion that the first telescopic sealing set 41 is connect with connecting tube 5 connects
In the annular recess of 5 one end of take over；One end insertion 5 other end of connecting tube that second telescopic sealing set 42 is connect with connecting tube 5
Annular recess in.Since connecting tube 5 only carrys out restriction site by two telescopic sealing sets, if the two are scalable close
When big envelope is only set in connecting tube 5, when reversed bay-type drinking-water switch frequently opens and closes, two telescopic sealing sets can repeated compression
And recovery, after long-time use, the case where telescopic sealing set can be caused to be disengaged from connecting tube 5, therefore, the two can be stretched
Contracting sealing shroud can effectively avoid the two telescopic sealings from being sleeved on for a long time in the connecting pin insertion connecting tube 5 of connecting tube 5
The case where being disengaged with connecting tube 5 after use.
Further, to make the connection between two telescopic sealing sets and connecting tube 5 more closely, first is scalable close
Big envelope 41 and the second telescopic sealing set 42 enter the part in the annular recess of connecting tube 5 and are interference between the annular recess
Cooperation.In the case of interference fit, to will be embedded in the groove of connecting tube 5 telescopic sealing set end from the groove
Take out, then need larger power, and in reversed bay-type drinking-water switch opening-closing process, telescopic sealing set by compressed restoring force not
It is enough to take out the end that the telescopic sealing being embedded in the groove of connecting tube 5 covers from the groove so that the two are scalable
Connection between sealing shroud and connecting tube 5 is more closely.
When two telescopic sealing sets are respectively sleeved on 31 outer wall of exhalant canal of water drinking tube 1 and faucet 3, connect
Termination process is easy and leakproofness is enough, as shown in Figures 2 and 3, one end that the first telescopic sealing set 41 is connected with water drinking tube 1

More closely, ribs 421 can ensure the second telescopic sealing set 42 and water outlet for the connection of flexible sealing shroud 41 and water drinking tube 1
The connection of 31 outer wall of exhalant canal of mouth 3 more closely, better ensures that its leakproofness.It is set in water drinking tube 1 or is set in
The end of telescopic sealing set on 31 outer wall of exhalant canal of faucet 3 will appear elasticity and reduces even after prolonged use
The case where being cracking, can effectively avoid telescopic sealing from covering 4 after the end set of telescopic sealing set has cyclic annular ribs
Both ends because long-time using occur elasticity reduce even crack the case where.
