Abstract
The utility model discloses a water and vapor mixed type water-saving joint which comprises a joint body, a water inlet channel and a water outlet channel, wherein the water inlet channel and the water outlet channel are arranged in a joint body cavity. The joint body cavity is further provided with an acceleration channel and an air cavity, the flow area of the acceleration channel is smaller than that of the water inlet channel, and the air cavity is isolated from the acceleration channel through a separation piece. The joint body is further provided with an air inlet hole communicated with the air cavity, and one portion, placed on the air inlet hole, of the joint body is provided with a single-pass device. With the structure, the water and vapor mixed type water-saving joint is simple in structure, water flow enters the acceleration channel from the water inlet channel, because the area is reduced, the water flow accelerates and drives the flow speed of air to be high, therefore, negative pressure is formed in the joint, the air enters the air cavity from the air inlet hole and is mixed with the water flow, then, the water phase and the vapor phase are formed, and the single-pass device arranged on the air inlet hole can prevent water from flowing back from the air inlet hole when water supply is stopped.
Description
Technical field
The utility model is specifically related to a kind of water-gas mixed water-saving joint.
Background technology
In daily life, we can cause a large amount of wastes when using common water pipe to carry out water, because the shortcoming of people's consciousness of saving water, custom reaches maximum with water in water (as the dish of washing one's hands), so that the area that washes away of water increases, reach reasonable cleaning performance.But such occupation mode makes that the dynamics wash away is excessive, is easy to generate sense of discomfort, and many water resources just are lost in vain, and is particularly all the more so in public places.
The utility model content
The purpose of this utility model provides a kind of simple in structure, saves the water yield, uses comfortable and can prevent from stopping to supply water the water-gas mixed water-saving joint of back water from the air admission hole refluence.
The technical solution adopted in the utility model is a kind of water-gas mixed water-saving joint, the intake tunnel and the exhalant canal that comprise joint body, joint body inner chamber, described joint body inner chamber also is provided with and is communicated with intake tunnel and the accelerated passage of exhalant canal and the air cavity that only communicates with exhalant canal, the circulation area of described accelerated passage is less than the circulation area of intake tunnel, described air cavity is isolated by barriers and accelerated passage, described joint body also is provided with the air admission hole that is communicated with air cavity, and joint body is positioned at air inlet position and is provided with the single-pass device.
Useful technique effect of the present utility model is: the water saving joint of this structure, simple in structure, current enter accelerated passage by intake tunnel, because area reduces, the speed of current will accelerate and drive the flow velocity of air to be accelerated, and makes and forms negative pressure in the joint, air then enters air cavity also and the current mixing from air admission hole, form the aqueous vapor two-phase, the single-pass device that air admission hole arranges is when stopping to prevent that sealing flows backwards from air admission hole after the water supply.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, intake tunnel; 2, accelerated passage; 3, exhalant canal; 4, air cavity; 5, air admission hole; 6, barriers; 7, single-pass device.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
A kind of water-gas mixed water-saving joint as shown in Figure 1, the intake tunnel 1 and the exhalant canal 3 that comprise joint body, joint body inner chamber, described joint body inner chamber also is provided with and is communicated with intake tunnel 1 and the accelerated passage 2 of exhalant canal 3 and the air cavity 4 that only communicates with exhalant canal 3, the circulation area of described accelerated passage 2 is less than the circulation area of intake tunnel 1, described air cavity 4 is isolated by barriers 6 and accelerated passage 2, described joint body also is provided with the air admission hole 5 that is communicated with air cavity 4, and joint body is positioned at air admission hole 5 places and is provided with single-pass device 7.Because the circulation area of the accelerated passage 2 of joint inner chamber is less than the circulation area of intake tunnel 1, current speed up when intake tunnel 1 flows into accelerated passage 2, current are taken away air in the joint and are made and form negative pressure in the joint, according to venturi principle, extraneous air just enters air cavity 4 by air admission hole 5, and form the aqueous vapor two-phase with current, reach the purpose of water saving.The aqueous vapor two-phase is mixed makes current softer, when washing one's hands or having a bath, the user can obtain more comfortable experience, and the circulation area of exhalant canal as shown in Figure 13 is arranged to become gradually big, make the flow speed of aqueous vapor two-phase further slow down, comfort level further increases.In addition, owing to be provided with a single-pass device 7 at air admission hole 5 ends, can guarantee that anti-sealing flows backwards when stopping to supply water from air admission hole 5.
Further, described barriers 6 is infundibulate.That is to say that the accelerated passage 2 that forms by funnelform barriers 6 again after current are by intake tunnel 1 accelerates.Best is that for convenient processing and manufacture, barriers 6 and joint body are one-body molded.Air admission hole 5 concrete and that air cavity 4 communicates is 1, an air admission hole 5 is set can realizes function fully.
Concrete, described single-pass device 7 is arranged on the joint body inwall, single-pass device 7 is arranged on prevents on the joint body inwall that single-pass device 7 is subjected to artificial destruction, single-pass device 7 uses easy hinge-type single-pass device 7, described hinge-type single-pass device 7 is made up of two parts up and down, flexibly connect between two parts, hinge-type single-pass device 7 simple structures, with low cost, air push hinge lower part enters air admission hole 5, enter air cavity 4 at last and mix with current, but because the hinge lower part is longer than air admission hole 5 apertures, current can not flow backwards by air admission hole 5.Certainly, single-pass device 7 also can use check valve.
