Abstract
The utility model provides an overflow and secondary pollution prevention cover for drinking machine, comprising a head cover body, an intelligent column and a vent pipe, and the intelligent column is opened with a hole communicated with the water bottle. The utility model is characterized in that in the vent pipeline, an overflow valve is connected in serious between the mouth of the vent pipe and the mouth of an air inlet pipe; a connection pipeline between the vent pipe and the overflow valve is provided with a filtering cotton; a screen pack is installed at the place of the mouth of the vent pipe, when air is leaked from the drinking water bottle resulting in that the pressure in the water bottle is out of balance, water flows through the overflow valve, and under the action of buoyant force, a valve stem hole is sealed by a valve core, to prevent the water in the drinking machine from overflowing; the filtering cotton is installed in the connection pipeline of the vent pipe and the overflow valve, and the filtering net is installed at the place of the mouth of the vent pipe, so dust, ants, insects, etc. in air are prevented from the drinking machine.
Description
Technical field
The utility model relates to a kind of water dispenser top cover.
Background technology
At present, its water bottle of bottled drinking water is turnover repeatedly and uses, the breakage of water bottle is inevitable, in a single day but the breakage of water bottle often is difficult for being it is found that, still is contained in when using on the water dispenser, because of outside air can directly enter in the water bottle, cause and lose pressure balance in the water bottle, the former ordinary water level of water dispenser can't keep, and the water in the water dispenser overflows from ventilative pipeline, causes the loss that do not have.
Water energy in the water dispenser water bottle is normally dirty to be because extraneous air can enter into the tank at top cover place from the ventilative pipeline place of the clever top cover of water dispenser, enters in the water bottle by clever post again.This shows; if not taking filtration measure and air to enter the mouth of pipe, outside air do not take safeguard measure then to be difficult to guarantee hygienic quality of drinking water; and its ventilative mode of water dispenser of market sale now mostly is a through type; promptly be outside air and enter the mouth of pipe, directly enter in the machine and in the water bottle without any processing.Like this, not only contaminated air can influence water quality, and extraneous hazardous materials such as tiny ant worm also can unblockedly directly enter in the water machine heavy damage water quality.
Summary of the invention
The purpose of this utility model is: the water dispenser top cover that a kind of anti-overflow, anti-secondary pollution are provided, it not only has and prevents to damage ventilative because of water bottle, cause the excessive of the interior water of water dispenser, prevent that dust in the air, ant worm etc. from entering the effect in the water dispenser but also have.
The utility model is achieved in that the water dispenser top cover of a kind of anti-overflow, anti-secondary pollution comprises top cover main body, clever post, permeability cell, clever post has the hole that communicates with water bottle, and its special character is: be connected in series an overflow valve between the ventilative ducted ventilative mouth of pipe and the air inlet mouth of pipe.
Described overflow valve comprises valve body, spool, and valve body has a upper valve core chamber, bottom spool chamber to stop up, and upper and lower spool chamber communicates by a valve rod hole; Spool comprises a upper valve core, bottom spool, valve rod, and upper and lower spool connects by valve rod; Gapped between valve rod and the valve rod hole.
In the connecting pipe of permeability cell and overflow valve by filter cotton is housed.
At ventilative mouth of pipe place by screen pack is housed.
At the air inlet place of permeability cell by ventilative over cap is housed.
The water dispenser top cover of anti-overflow of the present utility model, anti-secondary pollution, owing to be connected in series an overflow valve between the air inlet mouth of pipe and the air inlet mouth of pipe, when the gas leakage of drinking-water bottle, when causing the pressure disequilibrium in the water bottle, when the ordinary water level in the water dispenser can't keep, water entered overflow valve in water dispenser, and spool is under buoyancy function, bottom spool seals valve rod hole, thereby has prevented that the water in the water dispenser is excessive; In the connecting pipe of permeability cell and overflow valve, by filter cotton is housed, by screen pack is housed, prevent that dust in the air, ant worm etc. from entering the effect in the water dispenser so have at the air inlet place of permeability cell.
Description of drawings
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is the partial enlarged drawing of the utility model Fig. 1.
The specific embodiment
As shown in Figure 1, the water dispenser top cover of a kind of anti-overflow, anti-secondary pollution comprises top cover main body 1, clever post 11, permeability cell 4, between permeability cell 4 and air inlet pipe 10, by tube connector 5, overflow valve 7 of tube connector 9 serial connections; By screen pack 3 is housed, there is a ventilative over cap 2 to be installed in the air inlet place of permeability cell 4 at the air inlet place of permeability cell 4; Screen pack 3 can be the nylon screen pack, also can be the net of other filtration.
As shown in Figure 2, described overflow valve 7 comprises valve body 8, spool 7, and valve body 8 has a upper valve core chamber 81, bottom spool chamber to stop up 82, and upper and lower spool chamber 81,82 communicates by a valve rod hole 83; Spool 7 has a upper valve core 71, bottom spool 72, and upper and lower spool 71,72 connects by valve rod 73; Gapped between valve rod 73 and the valve rod hole 83, this gap is the passage of breathing freely with the external world in the water dispenser.
As further improvement of the utility model, in the pipeline of permeability cell 4 and the tube connector 5 of overflow valve 7 by filter cotton 6 is housed, but the dust in filter cotton 6 filtered airs etc. are guaranteed the cleaning of the air in the machine that enters, in the water bottle, thereby have been prevented the drinking water secondary pollution.
In actual use, if during the gas leakage of drinking-water bottle, cause the pressure disequilibrium in the water bottle, when the ordinary water level in the water dispenser can't keep, water enters overflow valve 7 in water dispenser, bottom spool 72 is under buoyancy function, and bottom spool 72 is with valve rod hole 83 sealings, thus the pressure balance in the maintenance drinking-water bottle.
