Abstract

In order to solve the problem that various inverted bubblers which supply water are polluted by air, the utility model provides a bubbler which supplies water in sub-pressure way. The proposal is that a water storing bottle is arranged in a bucket, a bucket cover can cover the mouth of the water storing bottle, and the bottom of the bucket is provided with a venthole. An obturating ring is arranged on the water conduit of the bubbler, and parts such as a triple valve, a holding valve or a reducing valve are positioned in connecting pipelines among various elements, which forms a closed pipeline of water supply. The whole process of water supply is carried out in the sub-pressure closed pipeline, thus liquid left in the bucket can not be polluted or deteriorated.

Description

The water dispenser of negative pressure water supply

Technical field

A kind of water dispenser of negative pressure water supply refers to household drinker especially.

Background technology

The use of water dispenser is more and more general.But water dispenser, beverage machine that the various inversion types of being sold in the market supply water are all leaned on entering of air, just can displace the liquid in the bucket, and this method of supplying water can cause harmful substances in air to pollute the interior remaining liq of bucket.Liquid in the particularly high hygienic requirements bucket is along with the prolongation air of the phase of drinking is just more outstanding to pollution, the spoilage problems that liquid caused.In addition, the turnover bucket easily is with dust because of the surplus water in cleaning dirty and the water fountain bucket seat and is entered in the water dispenser or the like problem, can cause the pollution problem of hiding again.

Summary of the invention

For the water dispenser that solves various inversion types water supply is subjected to the air-polluting problem, the utility model provides a kind of water dispenser of negative pressure water supply, its scheme is: place a water bag in bucket, the volume of water bag is close with the volume of bucket, Bucket Cover can cap seal water bag sack, the bottom of bucket is provided with passage.On the bucket seat of water dispenser, be provided with two one high and one low interface tubes, the contact site of aqueduct and Bucket Cover is provided with sealing ring, the lower end of aqueduct connects threeway, other two ends of this threeway connect the import of cold valves and check valve respectively, the outlet of check valve is connected with the water inlet of electrical heating water pot lower end, the gas outlet at electrical heating water pot top connects pressure-reducing valve, and the other end of pressure-reducing valve connects the air inlet pipe interface on the bucket seat.When being inverted in bucket on the water dispenser, the passage of bucket bottom is subjected to air pressure, and the compressing water bag makes the water in the water bag be divided into two the tunnel through behind the aqueduct by threeway, discharges hot and cold water purification by cold valves and hot water valve respectively.In the electrical heating water pot, Yin Jiawen and when producing too high pressure, this pressure flows in the water-collecting tray after the post-decompression unnecessary carbonated drink of pressure-reducing valve enters bucket seat again.Whole water supply process all carries out in the closed conduit under the negative pressure, and air can not enter in the interior water bag of bucket, thereby has avoided air pollution residue water quality, and each in addition back replacing water bag that uses has been avoided the pollution of hiding that causes because of bucket is cleaning dirty again.

Description of drawings

Accompanying drawing 1 is the utility model overall schematic.

Accompanying drawing 2 is the profile of bucket seat.

The specific embodiment

See also shown in the accompanying drawing, this water dispenser is made up of bucket 1 and water dispenser support 17.In the bucket 1 among the figure, place a water bag 3, water bag 3 can be a plastic sheeting, after filling water, the shape and the volume of the shape of water bag 3 and volume and bucket 1 are close, the sack of water bag 3 stretches out outside the mouth of bucket 1, the lid 7 of available bucket 1, with the sack of water bag 3 be locked in cover 7 with the bung contact site of bucket 1, the bottom of bucket 1 is provided with passage 2, after water bag 3 is filled water, covers the Bucket Cover 7 that first wife's water blocking 4 is housed, and with passage 2 outsides of bucket 1 bottom, with stand-by behind the viscosity gummed paper cap seal.Aqueduct 8 in the water dispenser support 17 is fixed on the bottom of bucket seat 5 inner chambers, aqueduct 8 is provided with sealing ring 6 with the contact site of Bucket Cover 7, the external diameter of sealing ring 6 is slightly larger than the internal diameter of Bucket Cover 7, the lower end of aqueduct 8 is connected to threeway 10, two ends in addition of threeway 10, connect the import of cold valves 11 and check valve 12 respectively, the outlet of check valve 12 is connected with the water inlet of electrical heating water pot 14 lower ends, the delivery port at electrical heating water pot 14 middle parts is connected with the water inlet of hot water valve 15, the gas outlet at electrical heating water pot 14 tops is by the air inlet pipe interface on pressure-reducing valve 16 access bucket seats 5 tops, and the drain interface of bucket seat 5 lowers one side inserts in the water storage tray 13 with hose adapter 9.

During use, when bucket 1 is inverted the bucket seat 5 that inserts water dispenser, water blocking 4 is backed down by aqueduct 8 immediately, remove the sticky paper in passage 2 outsides this moment, make passage 2 open-minded, water in the water bag 3 promptly is in the water supply state for the treatment of under the negative pressure, when unlatching is located at cold valves 11 or hot water valve 15 on the water dispenser support 17, when making interruption or continuous water supply, because of passage 2 is in opening state, make the water bag 3 of atmospheric pressure in passage 2 is added to bucket 1, make water bag 3 tops be in barotropic state, water in the water bag 3 produces suction function because of the high low head of liquid level, with the water in the water bag 3, press to aqueduct 8 after threeway 10 is divided into two tunnel, one road cooling water valve 11 and discharge cold water purification, another road flows into electrical heating water pot 14 through check valve 12, and the heating back discharges hot water purification by hot water valve 15.When electrical heating water pot 14 internal causes are heated and are produced too high pressure, this pressure is after pressure-reducing valve 16 decompressions, its unnecessary air water enters in the bucket seat 5, drain interface by bucket seat 5 bottoms is aggregated into water-collecting tray 13 with surplus water, in addition, bucket 1 insert or when extracting water dispenser left surplus water also the drain interface through bucket seat 5 bottoms flow in the water-collecting tray 13, enter the interior negative pressure water supply state of water bag so whole water supply process is in no air all the time, be subjected to the air-polluting problem with regard to not having remaining liq certainly.

The utility model can be applicable to the water dispenser that various inversion types supply water, and avoids air pollution, guarantees health.

Claims
