Abstract

The utility model discloses a ventilation funnel, which is characterized in that a channel 11 is provided in the funnel, and a ventilation chamber is provided at one side of the funnel. With the utility mode, residual water in the funnel can be eliminated to avoid secondary pollution to water retained in a water storage device so as to make a water dispenser form a hygienic water supply structure beneficial to people health.

Description

Air changing funnel

The utility model relates to the parts that are used for water dispenser, specifically a kind of Air changing funnel that matches with bottled water and water dispenser.

Along with the raising of people's living standard and the enhancing of health perception, bottled water reaches and the water dispenser of its coupling has entered average family and general public place, the water dispenser structure of Xiao Shouing is general as Fig. 1 in the market, the loam cake 5 of water dispenser is fixedlyed connected with water receiver 6, in water receiver, be provided with three passages 12,19,20, wherein passage 12 is communicated with hot courage, passage 19 is communicated with warm water tap or Cold-water bag, passage 20 is connected with the air leakage hole of hot courage, smart seat 4 is housed in water receiver 6, clever core 3 and clever rod 2 are housed on smart seat, the water bottle 1 of filled with water tips upside down on the clever rod 2 and by loam cake 5 and supports, water in the water bottle 1 injects water receiver 6 by clever core 3, water receiver 6 has stored a part of water and has played distributional effects, water flows to hot courage by passage 12, overflow gas in the hot courage from passage 20, normal-temperature water or frozen water are supplied water by passage 19, when water bottle 1 supplies water, air is through water and clever rod 2 in the water receiver 6, gap between the clever core 3 sucks, with the balance that keep-ups pressure, gap between clever rod 2 and the clever core 3 is interconnected, come down to a passage, obvious this water-supply structure causes secondary pollution inevitably, airborne bacterium is invaded the surplus water in the water receiver 6, and breeding therein.

The purpose of this utility model is to provide a kind of Air changing funnel, and it can avoid the surplus water in the existing water receiver to be secondary polluted.

The technical solution of the utility model is achieved in that Air changing funnel, and it mainly comprises funnel, is provided with passage in funnel, and clever rod is housed on funnel, it is characterized in that: also be provided with passage 11 in funnel, adorn an air-exchanging chamber in a side of funnel.

Use the utility model to save the interior water receiver of water dispenser, surplus water has avoided the surplus water in the water receiver to be secondary polluted in the funnel, makes water dispenser form a kind of water-supply structure of health, helps the healthy of people.

The utility model will be further described below in conjunction with drawings and Examples.

The utility model mainly comprises funnel 7, in funnel, be provided with passage 12,19,20, clever rod 2 is housed on funnel 7, it is different from prior art and is: also be provided with passage 11 in funnel 7, adorn an air-exchanging chamber 8 in a side of funnel 7, the air-exchanging chamber 8 of present embodiment has a housing 13, a side has a through hole 21 in the bottom of housing 13, and this through hole 21 is communicated with passage 11 in the funnel 7, forms an inlet channel, in housing 13, place a floating cup 14, a fixedly connected bowl cover 15 on floating cup 14 is established a rubber blanket 16 in the upper end of bowl cover 15, and a pressing plate 17 is arranged in the upper end of rubber blanket 16, on housing 13, also establish a lid 9, on pressing plate 17 and lid 9, be provided with pore; One screen pack 18 is arranged between lid on the housing 13 9 and pressing plate 17 in force, can carry out disinfection to air, rubber blanket is a resilient rubbber cushion, in housing 13, establish a dome ring 21 in the time of fixedly, rubber blanket 16 is contained on the dome ring 21, housing is cup-shaped, between the shell of the inwall of housing 13 and floating cup 14, leave gap 22, floating cup 14 in the utility model floats cup with the hollow cylindrical that bowl cover 15 has been formed a sealing, the similar ball float of its effect, can fluctuate at the housing 13 of air-exchanging chamber, the come-up distance is undertaken spacing by rubber blanket 16 and pressing plate 17, when water bottle 1 back-off of filled with water to loam cake 2, because the pressure of water bottle 1 will float cup 14 jack-up by passage 11, rubber blanket 16 is close in the upper surface of bowl cover 15, make the external and internal pressure of water bottle 1 keep balance, when opening the leading water supply start of water dispenser, water purification in the water bottle 1 flows out by passage 19 or passage 20, decompression in the water bottle 1, must be air-breathing, negative pressure in the water bottle 1 (pressure in the water bottle 1 and pressure differential of atmosphere) causes floating cup 14 to sink, make air pass through lid 9 and the pore of pressing plate 17 and the centre bore of screen pack 18 and rubber blanket 16 of air-exchanging chamber, and pass gap 22 between the inwall of floating cup 14 and housing 13, passage 11 enters in the water bottle 1, pressure in water bottle 1 reaches balance, whole air-exchanging chamber essence is a Non-return air valve, it is communicated with passage 11 by the through hole 21 in the funnel 7, form an inlet channel, only to water bottle 1 direct air feed, its each part is by the food grade materials manufacturing.
