Abstract
The utility model discloses an air-absorbing anti-backflow device which comprises an anti-backflow rubber plug and a joint. A water flow channel is formed in the joint axially. Air-absorbing holes are formed in the joint in a radial direction. The air-absorbing holes, the water flow channel and air are communicated. The anti-backflow plug has monodirectional water- transiting ability and the anti-backflow plug is installed in the joint. The anti-backflow plug is located on the position of a water outlet of the water flow channel. Water flows out of the joint after the water passes through the water flow channel and the anti-backflow plug. The air-absorbing anti-backflow device can be used normally in a low water-pressure condition. Strong water flow can be guaranteed and transparent white water columns can be saw through water outlet holes. Large-scale bubble water can be produced and water impulsion can be enhanced. The air-absorbing anti-backflow device can be applied to tall buildings and places of low water-pressure. Meanwhile, the air-absorbing anti-backflow device has an anti-backflow effect and an anti- tortuosity effect. Problems that residual water in bathroom instruments such as a shower can flow back and hosepipes can tie and crook can be solved when the water is stopped.

The specific embodiment
Below in conjunction with accompanying drawing embodiment is elaborated.
Referring to Fig. 1-11, the air-breathing anti-backflow device of present embodiment comprises anti-backflow plug 1, hex union 2, water sealing aprons 3, anti-distortion joint 4, interior plug 5, it is epimere 2-1, stage casing 2-2, hypomere 2-3 that hex union 2 can be divided into three sections, by three sections external diameters is successively from big to small: epimere 2-1, hypomere 2-3, stage casing 2-2.Hex union 2 inside form water stream channel along its axial (length direction), and this water stream channel comprises the main flow hole 2-4 that is in hypomere and be in the apopore 2-9 in stage casing that main flow hole 2-4 communicates with apopore 2-9.Radially uniform several suction holes of stage casing 2-2 2-5 of hex union, suction hole 2-5 and the external world and apopore 2-9 connect.
Clamping anti-backflow plug 1 in the epimere 2-1 of hex union, the material selection flexible glue material of anti-backflow plug 1, it is one-body molded by top and the bottom, the longitudinal section of top 1-1 is ∧ shape up, and the top of top 1-1 has the slit, under the inside water pressure effect, this slit can distending, but outside hydraulic pressure can't be with its distending; Bottom 1-2 is circular, and the circular hole at its middle part communicates with the end opening on ∧ shape top, is affixed on to lower seal the epimere of hex union and the 2-6 of radial transition section in stage casing, and the middle part circular hole of the apopore 2-9 of hex union and anti-backflow plug bottom 1-2 connects.The anti-backflow plug has the function of anti-backflow and water shutoff concurrently, and it has played aqueous reflux residual in the bathroom utensil and the effect of joint waterproofing plug of preventing.
Referring to Fig. 7,9, it is water inlet flow channel 2-7 that the hypomere 2-3 of hex union forms four road breach vertically, and the bottom of hypomere 2-3 is step-like (up) of evagination.
The outer cover of the hex union hypomere 2-3 distortion joint 4 of setting up defences, anti-distortion joint are joints that can 360 degree rotates, and its lower end is down step-like, thus with the lower end stage portion phase clamping of hex union hypomere 2-3.The upper surface of anti-distortion joint 4 is the concave/convex-shaped structure of rule, be affixed between the lower surface of the 2-6 of radial transition section of the protuberance of this upper surface and hex union, thereby make between the lower surface of the 2-6 of radial transition section of the recess of this upper surface and hex union and leave the gap, be used for ventilation.
Also be installed with water sealing aprons 3 between the hypomere 2-3 of anti-distortion joint 4 and hex union, to leak on the limit that prevents the distortion joint, play the water shutoff effect.
The lower port inside of the hex union hypomere 2-3 interior plug 5 of packing into, the hypomere inwall close-fitting of plug 5 and hex union in this is to prevent that twisting joint 4 is drawn out.But leave passage between interior plug 5 upper surfaces and the hypomere 2-3, this passage is inlet opening 2-8, and it connects water inlet flow channel 2-7 and main flow hole 2-4.
Referring to Fig. 6, air-suction: the thick arrow points among the figure is the flow direction of current, current enter inlet opening 2-8 from water inlet flow channel 2-7, through main flow hole 2-4 current are become straight line again and pour apopore 2-9, pass into the water inlet of anti-backflow plug 1, in this process, the air-flow that drives suction hole 2-5 enters (the thin arrow points among the figure is the flow direction of air-flow) again, thereby current and air are mixed into air-bubble, and then reach hydraulic pressure and increase technique effect about being twice.
Referring to Figure 11, the anti-backflow principle is: after current entered the water inlet of anti-backflow plug 1, the hydraulic pressure during owing to water inlet was larger, therefore, the back pressure (arrow downwards) in the hydraulic pressure in A district (to upward arrow) serious offense B district among Figure 11 is so the slit that current can be washed anti-backflow plug 1 top open sprays water.And when current stopped, then anti-backflow plug 1 can recover and keep original state, and was subjected to the kickback pressure (being back pressure, downward arrow among the figure) of residual water in the bathroom utensil to make the slit at its top closed, thereby reached the instead effect of stream.
The utility model is through optimal design, and its installations is very easy, can directly it be contained on the bathroom utensil such as gondola water faucet just can use, and the use state on the gondola water faucet of being contained in is referring to Figure 12,13, and it is that one of shower product is innovated greatly.During use, it should be noted that water outlet direction of the present utility model can not arrange stopping device afterwards, after no person cut off the water, leaking can appear in suction hole.
Those of ordinary skill in the art will be appreciated that; above embodiment illustrates the utility model; and be not that conduct is to restriction of the present utility model; as long as in essential scope of the present utility model, all will fall into protection domain of the present utility model to variation, the modification of the above embodiment.
