A kind of water dispenser is purifier again

Technical field

The utility model relates to the water dispenser technical field, mainly is the water dispenser that proposes for the secondary pollution problem that solves water dispenser purifier again.

Background technology

Water dispenser secondary pollution problem, be meant that the drink water after barreled drink water, special water purifier for drinking machine purify flows through from the water circuit system of water dispenser, flow out from the water fountain effluent tap again, its water quality index is on a declining curve, show that mainly water turbidity rises, the bacterial population in the water increases.The nearly all water dispenser of this problem is ubiquity all.Its reason is:

1, the water in the water dispenser bucket directly communicates with extraneous air, and dust in air, bacterium directly enter in the water, produces secondary pollution;

2, the water in the water dispenser is may the access time long, produce microbial reproduction, and water dispenser itself does not have sterilization, bacteria resistance function or sterilization, bacteria resistance function not to meet the demands.

At this problem, more existing patented technology schemes.For example, what have is provided with the sterilization nonwoven at the water fountain effluent mouth, and what have puts into sterilization or antibacterial material etc. in the water dispenser bucket.These methods have certain effect to preventing out the water generates secondary pollution, but reliability is not high, because these active ingredients antibacterial or sterilization material can be separated out in water gradually, concentration can be more and more lower, after a period of time, have in addition a couple of days after, its sterilization or fungistatic effect just disappear.

Therefore, be badly in need of to occur on the market a kind ofly can avoiding the bigger water dispenser of drinking water secondary pollution, clean water quality degree height, water flow purifier more reliably, guarantee user's health of drinking water with this.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of water dispenser that can solve water dispenser secondary pollution problem effectively, reliably purifier again is provided at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this water dispenser is purifier again, comprise the water dispenser bucket, the bucket delivery port is connected with the water pump that boosts, exit of pump is connected with the doughnut filter core that filtering accuracy is enough to bacterium in the filtering water reliably, and the filter core delivery port is the water fountain effluent mouth.

Described water dispenser bucket, water wherein directly communicates with extraneous air, and dust in air, bacterium directly enter in the water, produce secondary pollution; In addition, these water possibilities are longer memory time, and easy therebetween breed bacteria produces secondary pollution.Near the water fountain effluent mouth doughnut filter core is being set, all handle instant purifying from the water that the water fountain effluent mouth flows out through Hollow Fiber Ultrafiltration, remove the bacterium that may exist in anhydrating and other dust, impurity, can guarantee water outlet cleaning, health, non-secondary pollution.Described water pump is used to provide the resistance that produces when overcoming current by the doughnut filter core.Described doughnut can be a high-hydrophilic, also can be low hydrophilic.When adopting high hydrophilic doughnut, resistance to water-flow is little, discharge is big, pump energy consumption is little; Because the water that enters before the doughnut fully purifies, the service life of doughnut is also longer.Because doughnut filter core delivery port is the water fountain effluent mouth, so the water that purifies through Hollow Fiber Ultrafiltration can not produce pollution once more.It is generally acknowledged that bacterium is of a size of 0.4 micron, so, as long as the filtering accuracy of control doughnut is not less than 0.3 micron, just can reach good bacteria-eliminating efficacy.For further improving the degerming reliability, preferably adopt filtering accuracy to be not less than 0.1 micron hollow-fiber module.

For the water dispenser that compressor cooling or electronic cooling are arranged, can be with the delivery port of cold jar water inlet water receiving bucket, the water inlet of cold jar delivery port water pump.Water in cold jar enters hollow-fiber module after water pump boosts, flow out from the water fountain effluent mouth after doughnut purifies.May there be water instant purifying when the user takes of microbial contamination in cold jar, guarantees cold water water outlet cleaning, health, non-secondary pollution.

Compared with prior art, advantage of the present utility model is: the utility model can guarantee that the user is in water intaking, current are all handled by doughnut filter core instant purifying, and water pump is arranged as power, both can guarantee that the water outlet microbiological indicator was qualified, and can reduce the turbidity of water again, water flow is bigger simultaneously, satisfy the moment user and take water yield requirement, thereby effectively solve the ubiquitous secondary pollution problem of water dispenser.
