Description
Technical field
The present invention relates to the water dispenser technical field, refer in particular to a kind of water dispenser that prevents secondary pollution.
Background technology
Water dispenser secondary pollution problem is meant that the barreled drink water flows through from the water circuit system of water dispenser, flow out from the water fountain effluent valve again, and its water quality index is on a declining curve, shows that mainly water turbidity rises, and the bacterial population in the water increases.Its reason is:
1, the space of bottled water discharge water is by the replenish air without purified treatment;
2, the water in the water-purifying tank is may the holding time long, grows microorganism.
At this problem, people have also designed the water dispenser that can prevent secondary pollution, for example, China Patent No. is 200420082321.2 " a kind of bagged water dispensers ", this water dispenser comprises water bag, jockey and water dispenser, the central authorities of described jockey are provided with thorn bag seal-locking mechanism, and this mechanism comprises thorn bag mozzle, flexible sealing ring, fork, handle and extension spring.When pressing fixed handle, the fork swing makes the upper end taper tartar of thorn bag mozzle puncture water bag, under the extension spring effect fork is resetted rapidly then, and the taper tartar of thorn bag mozzle moves down the locking seat cushion of locking holder water bag container, plays sealing function.This water dispenser has anti-secondary pollution function preferably.But this water dispenser can not utilize tens million of water-purifying tanks that using on the market.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of novel water dispenser that prevents secondary pollution at the deficiency of above-mentioned prior art present situation, this water dispenser can utilize existing water dispenser and water-purifying tank, and the same with common water dispenser simple and convenient when using.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of water dispenser that prevents secondary pollution, it is provided with the bracing or strutting arrangement that can support water-purifying tank above bucket, this bracing or strutting arrangement comprises supporting seat and is located at the base plate of supporting seat below, supporting seat be provided with air inlet and can insert in the water-purifying tank and can with the core pipe of water-purifying tank opening part sealing, be provided with purifier on the inlet channel or on the exhalant canal.
In the purpose that purifier is set on the inlet channel is will remove airborne dust and be attached to bacterium on the dust, prevents that entering water-purifying tank without the air that purifies pollutes water generates wherein.The purpose that purifier is set on exhalant canal is the drinking water in the water-purifying tank will to be purified once more, removes bacterium and other suspension that may exist in anhydrating, and guarantees that really the water microorganism index that enters in the bucket is qualified.Also can simultaneously on the inlet channel He on the exhalant canal purifier be set all, like this water dispenser prevent to produce the function of secondary pollution will be stronger, more reliable.
Being arranged on purifier on the exhalant canal and can being the doughnut filter core that can effectively remove bacterium and suspension in the water, can be the cotton filter core of PP that can effectively remove bacterium and suspension in the water, also can be other filter core that can effectively purify water.
The purifier that is arranged on the inlet channel can be effectively to remove dust and the doughnut filter core that is attached to the bacterium on the dust in the air, also can be effectively to remove dust and cotton filter core of the PP that is attached to the bacterium on the dust or nonwoven filter core in the air.
When inlet channel communicates with atmosphere all the time, promptly need only when having negative pressure in the water-purifying tank, extraneous air just can replenish in water-purifying tank by inlet channel, at this moment, should altitude valve be set on exhalant canal, and check valve is set on inlet channel.The effect of altitude valve is when the water level in the bucket rises to desired location, and this valve closing prevents that the water in the water-purifying tank from continuing to replenish to bucket by exhalant canal; The effect of check valve is only to allow air to enter water-purifying tank by this valve, and does not allow the water in the water-purifying tank to flow into bucket by this valve.
The technical measures that the present invention taked also comprise: by screw sealing ring is fixed therein between described base plate and the supporting seat, the sealing circle can be with supporting seat and water dispenser upper end outside seal; Also be provided with radial groove on the described base plate, be equipped with on the groove and can radially regulating and by the fixing locating piece of nut, so that described bracing or strutting arrangement firmly is connected with the water dispenser housing.
Described altitude valve can be float-controlled valve or ball-cock assembly, and it can utilize the buoyancy of float or ball float to control water level automatically.Described altitude valve also can be a magnetic valve, and it can obtain water level signal by level sensor, with the keying of this signal controlling magnetic valve.
In the technology of the present invention, the air that enters in the water-purifying tank is earlier removed dust wherein and is attached to bacterium on the dust through purifier, the water that perhaps flows out from water-purifying tank flows into bucket earlier again after purifier is except that the bacterium that may exist in anhydrating and other suspension, the former can prevent effectively that directly entering water-purifying tank without the air that purifies pollutes water generates wherein, and the water microorganism index that the latter can guarantee to enter in the bucket is qualified.So, the present invention can prevent that the drinking-water function of secondary pollution from solving the secondary pollution problem effectively, and can utilize existing water dispenser and water-purifying tank, during use, smart seat with common water dispenser takes off earlier, reinstall described bracing or strutting arrangement, can equally with common water dispenser use simply, easily.
