Abstract

The utility model relates to a water adding device for a domestic drinker. A sealed column container is formed by joining an upper half and a lower half. An inlet valve on the upper end face of the utility model is connected with a piston rod. A spring force is used for regulating air pressure in the sealed column container, realizing that directly drunk pure water in a high pressure pipeline has a constant low pressure and outside air is isolated to add water into a domestic drinker.

Description

A kind of priming apparatus of water dispenser

The utility model relates to a kind of priming apparatus of household drinker.

At present, known household drinker adds water, has by manually adding water with container to water dispenser, and also useful pure water bottle adds water to water dispenser.Manually add water, directly drink pure water and air, add the container that water uses and contact, all straight drink pure water is had pollution with container.Add water with pure water bottle to water dispenser, the water dispenser air admission hole is big, has dust, mosquito, and bacterium makes straight drink pure water water quality be subjected to secondary pollution with entering in straight drink pure water in the pure water bottle and the volume of air exchange process.Along with the progress of society, quality classification water supply progressively rises, and pipeline is directly drunk pure water and progressively entered huge numbers of families, and the household drinker water feeding method has been proposed the improvement requirement.

The purpose of this utility model provides a kind of priming apparatus of household drinker, can not only add straight drink pure water to household drinker, and pipeline directly drinks pure water and directly enter household drinker through this priming apparatus, does not contact with air, does not have secondary pollution.

The purpose of this utility model is achieved in that an O-ring post container that is connected into by the first half, Lower Half, and there are piston cylinder and outer microgroove pipe in first half upper surface, is installed into water valve on the outer microgroove pipe, and DI UNICOM is directly drunk with pipeline in the water intaking valve upper end.Dress piston element, large sealing packing ring, small sealing ring and spring in the piston cylinder.Piston element is associated in the water intaking valve handle.There are three mouths of pipe the Lower Half bottom surface, and two is delivery port, and one is air inlet.Straight drink pure water reduces in O-ring post container, piston element is descended by spring action, piston element drives the water intaking valve handle and rotates, open water intaking valve, directly drink pure water and enter O-ring post container, compress wherein air, its chamber pressure increases, compressed air promotes piston element and up moves, and piston element drives the water intaking valve handle and rotates, and closes water intaking valve.Along with water dispenser discharges water, O-ring post container middle water level descends, pressure reduces, when spring force greater than O-ring post container compressed air during to the holder power of piston element, piston element is promoted to move down by spring, drives water intaking valve hand tenon and rotates, open water intaking valve, add water for O-ring post container, repeat to open, close water intaking valve like this, make water dispenser add straight drink pure water and be in constant low-pressure state for a long time.

Owing to adopt to go up fast scheme, straight drink pure water does not contact with outside air the priming apparatus of household drinker in the water process adding to water dispenser, is not subjected to the erosion of dust, bacterium and mosquito in the outside air, avoids pipeline directly to drink pure water and is subjected to secondary pollution.

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is a structure chart of the present utility model.

1. first halves, 2. water intaking valves, 3. pipelines are directly drunk DI 4. handles 5. piston elements 6. small sealing rings 7. springs 8. large sealing packing rings 9. Lower Halves among the figure

In the accompanying drawings, the first half (1) is connected into O-ring post container with Lower Half (9).The first half (1) is uniform several projectioies on the outer garden, so that be fixed on the household drinker, end face has piston cylinder and outer microgroove pipe.Lower Half (9) is one garden, end tube, and there are three mouths of pipe the bottom surface, and two is delivery port, and one is air inlet, three mouths of pipe and water dispenser UNICOM.Male-pipe on the first half (1) and water intaking valve (2) UNICOM O-ring post container, the upper end of water intaking valve (2) is directly drunk DI with pipeline and is communicated.Piston element (5), small sealing ring (6), spring (7), large sealing packing ring (8) are installed in the piston cylinder on the first half (1) end face, and the piston rod of piston element (5) is associated in the handle (4) of water intaking valve (2).Straight drink pure water reduces in O-ring post container, cavity pressure descends, piston element (5) is descended by the effect of spring (7), driving hand tenon (4) rotates, open water intaking valve (2), directly drink pure water and enter air in the compression seal garden post container in the O-ring post container, when its cavity pressure is increased to pressure greater than spring (7), compressed air promotes piston element (5) and goes up shipper pole fixed handle (4) rotation, closes water intaking valve (2).Water dispenser discharges water, water level descends in the O-ring post container, and pressure descends, and the holder power of giving piston element (5) when its chamber compressed air is during less than the pressure of spring (7), piston element (5) moves down and drives handle (4) rotating opening water intaking valve (2), and pipeline is directly drunk pure water and added in the O-ring post container.Repeat to open, close water intaking valve (2) like this, avoid pipeline and directly drink high pressure in the pure water system pipe, make water dispenser add pipeline and directly drink pure water and be in constant low-pressure state for a long time to guarantee household drinker.

Claims

1, a kind of household drinker priming apparatus, put into water valve, piston element, small sealing ring, large sealing packing ring, spring on the O-ring post container upper end face, it is characterized in that: the first half and Lower Half are connected into O-ring post container, put into water valve on the male-pipe of first half upper surface, the water intaking valve other end and pipeline are directly drunk DI UNICOM, adorn piston element, spring and sealing ring in the piston cylinder.Lower Half has three mouths of pipe.

2, according to the described household drinker priming apparatus of claim 1, it is characterized in that: the piston rod of piston element is associated in the water intaking valve handle.
