Description

Novel clever seat with preventing secondary pollution function
Technical field
The present invention relates to the water dispenser technical field, refer in particular to a kind of novel anti-secondary pollution drinking water machine smart seat.
Background technology
Now, water dispenser has been a kind of drinking device that people generally use, and still, also there are some places that require further improvement in water dispenser.For example: people are when the tap of water dispenser discharges water, can find to have bubble to enter water-purifying tank on the water dispenser, this is because the relation of atmospheric pressure, water dispenser when discharging water, must have with the water of emitting with the replenish air of volume, could normally discharge water,, will in water-purifying tank, bring a certain amount of dust and bacterium into along with entering of these air, thereby make the water quality deterioration in the water-purifying tank, produce secondary pollution.According to document announcement, 4,000,000 on bacterium is arranged in every cubic metres of air in the crowded market, also there are 580,000 in every cubic metres of air on the tree-covered walkways.So air is a very important problem to the pollution of drinking water.
At the problems referred to above, people have also designed the smart seat of water dispenser of anti-secondary pollution, are a kind of smart seat " the water dispenser single channel ventilation smart seat " of 98247119.X disclosed as China Patent No..This smart seat comprises pedestal, seat core, cover for seat, dished sealing washer, ventilative seat, moisture trap, a side is provided with an air inlet outside pedestal suitable for reading, this air inlet place is provided with filters the disinfectant film, is provided with sealing ring between the contact-making surface of smart seat and water dispenser side's lid.This smart seat is owing to sealed the passage of other possible air inlet of institute, only stay unique passage ventilation, and be provided with at this passage place and filter the disinfectant film, therefore solved because the drinking water secondary pollution that ventilation is brought, and make the replacing of filtering the disinfectant film easier, be convenient to the user and change voluntarily.But also there are the following problems for this patented technology smart seat:
1. the user in use if know that filtering the disinfectant film lost efficacy, can in time change, but whether problem is the user and does not know to filter the disinfectant film and lost efficacy;
2. only depend on the sealing ring of two simple and easy assemblings seal other might air inlet passage, in theory perhaps this be feasible, and be insecure on the product of reality.Because the size of water dispenser bucket and Fang Gai is bigger, generally made of plastic, and also wall thickness is thinner, so in production, transportation and use, all compare easy deformation.Here said unreliable two implications that have, the first can not guarantee reliably that the water dispenser that dispatches from the factory in enormous quantities each and every one all has good sealing; Its two be can not guarantee reliably water dispenser after long-distance transport and long-time use of user still have good sealing afterwards;
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of novel clever seat with preventing secondary pollution function at above-mentioned prior art present situation, this smart seat can be handled effectively to all air that enters in the water-purifying tank, filtering bacterium and dust wherein, thus make the drinking water in the water-purifying tank avoid secondary pollution.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of novel clever seat with preventing secondary pollution function, comprise clever pedestal and the clever pipe of fixedlying connected, it is characterized in that: the hydrophobic hollow fiber that is provided with bacterium in the effective filtering air in the described clever pipe with clever pedestal.
Described clever pipe comprises body, hollow-fiber module and ventilating cover.Described body and hollow-fiber module can adopt screw thread and sealing ring fixed seal connection, also can adopt welding or bonding to carry out fixed seal connection.The inside of described body is provided with and space in the pipe can be divided into two-part dividing plate, and wherein a part is an exhalant canal, and another part is an inlet channel, and two parts are separate, are not communicated with.The upper and lower end of described inlet channel does not all seal, and upper end open is communicated with the inner chamber of hollow-fiber module, and the lower end has air inlet and is communicated with the water dispenser bucket.The upper end closed of described exhalant canal is not communicated with the inner chamber of hollow-fiber module, and the lower end has delivery port so that be communicated with the water dispenser bucket, is having water inlet near on the sidewall of upper end.Described delivery port position is lower than the air inlet position.
Described hollow-fiber module is by very thin (about 1 millimeter) of numerous diameters and be converted into two ends hydrophobic doughnut of " U " shape and housing up and form, and the end of this doughnut is adopted binding agent to make it to be sealing adhesive mutually and is sealing adhesive with the madial wall on housing top and is integral.Described doughnut has good antibacterial properties, chemical stability, and nontoxic, harmless, reaches foodstuff sanitation-stage, and its filtering accuracy satisfies the requirement of airborne bacterium of effective filtering and tiny dust.Average-size that it is generally acknowledged bacterium is 0.4 micron, so as long as the filtering accuracy of doughnut just has good bacteria-eliminating efficacy less than 0.3 micron.For the reliability that improves degerming preferably adopts filtering accuracy is 0.1 micron doughnut.Because it is big that hydrophobic doughnut has a water flowing resistance, the characteristics that aeration resistance is little, so (pressure is very little) this doughnut can be accomplished the not water flowing of only ventilating under application conditions of the present invention, thereby it is unimpeded that gas circuit is easier to.
Described ventilating cover is fixedly connected on the upper end of hollow-fiber module, which is provided with venthole, and the effect that it has protection hollow-fiber module upper end has certain ornamental simultaneously.
Described clever pipe, because its diameter is less, its size and distortion are all than being easier to control, so each requires the sealing part to guarantee sealing easily.
The mode of fixedlying connected between described clever pedestal and the clever pipe can be to adopt engage thread to be tightly connected by sealing ring, nut; Also can be to adopt welding manner to be tightly connected; Also can be to adopt bonding mode to be tightly connected; Also can be to adopt the mode of buckle to be tightly connected; Also can be that bottom (being body) with clever pipe becomes a complete part with the smart seat system, the bottom of clever pipe (being body) fixedlys connected with hollow-fiber module again.
The technical measures that the present invention taked also are included in the delivery port place current limliting part that can carry out current limliting to water flow are set, this current limliting part is provided with the metering hole of sectional area very little (for example diameter is not more than 5 millimeters circular hole), enters from delivery port to prevent gas.Described metering hole can be an aperture that sectional area is less, also can be the littler aperture of a plurality of sectional areas.
During use, novel clever seat with preventing secondary pollution function of the present invention is installed on the water dispenser housing, and its underpart is stretched in the bucket of water dispenser, and water-purifying tank tips upside down on the smart seat.Drinking water in the water-purifying tank has the trend that flows in bucket under the gravity effect.Because doughnut has hydrophobic property, the drinking water in the water-purifying tank can not pass doughnut and flow out from inlet channel, can only flow into exhalant canal from water inlet, and the delivery port from the exhalant canal lower end flows into the water dispenser bucket again.Outflow along with drinking water in the water-purifying tank, to produce certain negative pressure in the water-purifying tank, because the relation of atmospheric pressure, drinking water goes out hydrodynamic force and will reduce in the water-purifying tank, at this moment, the air in the bucket will suck inlet channel from the air inlet of inlet channel lower end, enter the inner chamber of hollow-fiber module again, pass the tube wall of hydrophobic doughnut then, enter in the water-purifying tank.Air is when passing the doughnut tube wall, and bacterium wherein and tiny dust are trapped within the tube wall outside of the doughnut of porous, so air is purified.Along with the benefit of air is gone into, the negative pressure in the water-purifying tank will reduce, so the drinking water in the water-purifying tank obtains out hydrodynamic force again, current continue to flow in the water dispenser bucket, and the water level in the bucket rises thereupon.When air inlet is flooded in the water level rising, inlet channel will stop to carry air in water-purifying tank.At this moment, will produce certain negative pressure in the water-purifying tank, under the atmospheric pressure effect, the drinking water in the water-purifying tank will stop to flow in bucket, and the water level in the bucket will remain on certain position.When the user when the water dispenser tap discharges water, the water level in the bucket just descends thereupon.When water level drops to when exposing the air inlet position, because the delivery port position is lower than the air inlet position, delivery port is still lived by water seal, air can not enter from delivery port, can only suck inlet channel from air inlet, pass the tube wall of hydrophobic hollow fiber then, enter in the water-purifying tank, so the drinking water in the water-purifying tank obtains out hydrodynamic force once more, beginning is to the moisturizing of water dispenser bucket.If the user constantly discharges water from the water dispenser tap, inlet channel just constantly replenishes air in water-purifying tank, and the drinking water in the bucket just constantly flows in the water dispenser bucket, till the drinking water in water-purifying tank has been put.If the user stops to discharge water from the water dispenser tap, then the bucket middle water level will rise, when water level rise to flood air inlet after, water-purifying tank stops again to the bucket moisturizing, the water level in the bucket returns to original position again.The water dispenser that novel clever seat with preventing secondary pollution function of the present invention is housed is exactly to supply drinking water to the user by such principle.
Because the hydrophobic hollow fiber diameter is very thin, can in less volume, hold the doughnut of many radicals, filter area is bigger, so the service life of doughnut can be very long.Doughnut is after using for a long time, contaminated thing is stopped up gradually, and water fountain effluent can be more and more not smooth, and this phenomenon is easy to and is certain to found by the user, so the hollow-fiber module that the user can in time more renew, thereby ensure that the drinking water in the water-purifying tank is not subjected to secondary pollution.
Effect of the present invention is: when each user fetches water from the water dispenser tap, the air that enters in the water-purifying tank all passes through purified treatment, filtering bacterium and tiny dust wherein, thereby the trouble and worry of drinking person has been eliminated in the drinking water secondary pollution that brings when having solved the water-purifying tank tonifying Qi.
Compared with prior art, advantage of the present invention is that the drinking water anti-secondary pollution method in the water-purifying tank is reliable, is used for the bacterium of entrapped air and the hydrophobic hollow fiber long service life of dust, doughnut is easy to and is certain to be found after in a single day stopping up, and is convenient to timely replacing.
