As the utility model adopts the structure that the side of the sewage chamber is made open, and communicated with the gap formed between the tap shell and the tap body, thereby realizing that the sewage chamber is communicated with external air, and avoiding arranging a vent hole on the tap shell, and ensuring the integrity of the appearance of the tap shell and beauty of the appearance of the whole tap.

Description

The anti-syphon structure of tap

Technical field

The utility model is about a kind of water outlet device, is meant that especially a kind of tap prevents syphon structure.

Background technique

Usually the tap of the anti-siphon function of tool is arranged in the water purifying plant, and its inside is provided with the shunting water route so that the water purification after will filtering is introduced in the water inlet path, and sewage can flow into the drainage channel from the another one water route.For preventing that sewage from flowing backwards, then need in the sewage path, be provided with the vent that communicates with ambient atmosphere and constitute anti-syphon structure.

As shown in Figure 1, 2, existing tap is prevented syphon structure, it comprises a leading shell 1 ', a faucet body 2 ' and a syphon tube, faucet body 2 ' is provided with two water-inlet cavitys 21 ', 22 ' from bottom to top, one water purification water-inlet cavity, 21 ' sidewall is provided with the water outlet that is connected with effluent control device, and this effluent control device control water purification flows out from water tap; And syphon tube to be the stopper of a tool two conduits place soil chamber 22 ', wherein a conduit is that the middle part disconnects and communicating with soil chamber 22 ', this soil chamber 22 ' sidewall is provided with a vent 221 ' and communicates with the external world; Tap shell 1 is to cover at outside the faucet body 2 ', be provided with equally and the corresponding matching hole of faucet body 2 ' water outlet, corresponding vent 221 ' at faucet body 2 ' also is provided with vent 11 ', this vent 221 ', 11 ' setting just, make when this tap is in negative pressure state, sewage can not flow backwards, and only is that gas enters syphon tube from the pipeline that disconnects, and prevents pollution of waterhead with this.

The anti-siphon tap of said structure is owing to need to offer vent 11 ' on the leading shell 1 ' sidewall, is subjected to the restriction of vent 11 ' during leading shell 1 ' moulding and assembly line can occur, and influence the integrity and the aesthetic property of leading shell 1 ' outward appearance.

The model utility content

The purpose of this utility model is to provide a kind of not to be influenced leading shell integrity and guarantees that leading shell tap attractive in appearance prevents syphon structure.

For achieving the above object, solution of the present utility model is: a kind of tap is prevented syphon structure, comprise leading shell, faucet body and syphon tube, the tap shell is that the enclosure is on faucet body, two water-inlet cavitys that faucet body forms from bottom to top, wherein syphon tube is to be fixed in the soil chamber, water-purifying cavity by control gear control water outlet whether, wherein: the middle part of this soil chamber is opened wide with leading shell and is communicated with crack mutually between the faucet body.

After adopting such scheme, because the utility model is to adopt the soil chamber sidepiece disconnected with leading shell to communicate with gap between the faucet body, then can realize the function that this soil chamber communicates with ambient atmosphere, need not on leading shell, to establish in addition vent, thereby guarantee the integrity of leading casing appearance, guarantee the aesthetic property of whole leading outward appearance.

Fig. 2 is a side view of commonly using leading shell;

Fig. 3 is a three-dimensional exploded view of the present utility model;

Fig. 4 is a work schematic representation of the present utility model (sectional view).

Embodiment

Shown in Fig. 3,4, tap of the present utility model is prevented syphon structure, and it comprises a leading shell 1, a faucet body 2 and a syphon tube 3, and leading shell 1 is to cover at outside the faucet body 2, and syphon tube 3 is to place faucet body 2.

Tap shell 1 is a housing, and its top is to connect outlet pipe, and its sidewall is provided with the matching hole 11 that connects control gear;

Faucet body 2 is formed with a water-purifying cavity 21 and a soil chamber 22 from bottom to top, and water-purifying cavity 21 communicates with the water-purifying pipe of bottom, and is fixed with syphon tube 3 in the soil chamber 22;

Syphon tube 3 is to be made of two bodys 31,32 and the connecting sheet up and down 33,34 that connects two bodys 31,32, and this connecting sheet 33,34 and above-mentioned soil chamber 22 are suitable, and the middle part of its middle tube body 31 forms two sections bodys 311,312 for disconnecting partly with body 31.

Key of the present utility model is: the middle part of the soil chamber 22 of faucet body 2 is opened wide to communicate with gap between the faucet body 2 with leading shell 1, realizes that with this soil chamber 22 communicates with ambient atmosphere.

Cooperate shown in Figure 4, this syphon tube 3 is to utilize last connecting sheet 34 to cooperate with the lower seal of soil chamber 22, and go up connecting sheet 33 is to cooperate with the top seal of soil chamber 22 to form an airtight chamber 221, during work, water purification enters outlet pipe from water-purifying cavity 21 controlled device controls, and sewage is to enter airtight chamber 221 and flow out from body 311 along body 32, and flows in the body 312 of aiming at body 311 and discharge from sewage pipe; When tap is in negative pressure state, because body 31 is for disconnecting and communicating with soil chamber 22, and soil chamber 22 and leading shell 1 communicate with gap between the faucet body 2, then gas can enter the body 311 from this gap and keep air pressure balance in the pipeline, preventing that sewage from flowing backwards from body 312 enters in the body 311, not contaminated to guarantee the water source, thus realize leading anti-siphon function.

By said structure as can be known, the utility model is to have utilized the gap that communicates with atmosphere between faucet body 2 and the leading shell 1 and be communicated with soil chamber 22, can guarantee that so leading shell 1 does not need to offer in addition through hole on sidewall, guarantee the integrity and the aesthetic property of leading shell 1 with this.

Claims (1)

1. a tap is prevented syphon structure, comprise leading shell, faucet body and syphon tube, the tap shell is that the enclosure is on faucet body, two water-inlet cavitys that faucet body forms from bottom to top, wherein syphon tube is to be fixed in the soil chamber, by control gear control water outlet whether water-purifying cavity is characterized in that: the middle part of this soil chamber is opened wide with leading shell and is communicated with crack mutually between the faucet body.
