The application is further described below by drawings and examples.Illustrated by these, the characteristics of the application It will be become more apparent from advantage clear.

Dedicated word " exemplary " means " being used as example, embodiment or illustrative " herein.Here as " exemplary " Illustrated any embodiment should not necessarily be construed as preferred or advantageous over other embodiments.Although each of embodiment is shown in the attached drawings In terms of kind, but unless otherwise indicated, it is not necessary to attached drawing drawn to scale.

In addition, as long as technical characteristic involved in the application different embodiments disclosed below is not constituted each other Conflict can be combined with each other.

As illustrated in fig. 1 and 2, a kind of tap provided by the present application comprising:

It is internally provided with the tap main body 1 into water tube passage 11 and water outlet tube passage 12,11 He of water inlet tube passage Water outlet tube passage 12 is communicated in the tap main body internal flow,

A part of water inlet pipe 2, the water inlet pipe 2 is arranged in the water inlet tube passage 11 of the tap main body, and one Quartile is in the outside of the tap main body 1；

A part of outlet pipe 3, the outlet pipe 3 is arranged in the water outlet tube passage 12 of the tap main body, and one Quartile is in the outside of 1 body of tap master；

Wherein, it is internally provided with non-return valve 13 in the tap main body 1, the non-return valve 13 is set to positioned at the water Between water inlet pipe 2 inside tap main body and outlet pipe 3.

In this application, a part of the water inlet pipe 2 is arranged in the water inlet tube passage 11 of the tap main body, and one Part is located at the outside of the tap main body 1；A part of outlet pipe 3, the outlet pipe 3 is arranged in the tap main body Water outlet tube passage 12 in, a part be located at 1 body of tap master outside.In one embodiment, the end of outlet pipe 3 Portion and the junction of water outlet tube passage 12 are provided with sealing ring 31.Outlet pipe 3 also has water outlet 33, for outwardly exporting Water.Water inlet pipe 2 has water inlet 23, can be used for connect with external water source such as water purifier etc., for tap water supply.

In this application, non-return valve 13 is located at the inside of tap main body 1, and arrival end is towards water inlet pipe 2.Non-return valve is Refer to and is flowed and automatic open and close flap by medium itself, for the valve for preventing medium from flowing backwards, also known as check-valves, check valve, inverse Flow valve and counterbalance valve etc..Non-return valve for the application tap can use various non-return valves known in the art, such as bullet Spring formula non-return valve etc..The structure and working principle of the known spring non-return valve of those skilled in the art, for spring non-return valve For, medium enters valve body by arrival end, pushes valve rod, spool to move upwards, valve opening；When medium is flowed back by outlet end When, spool, valve rod act rapidly under the effect of the pressure of spring force and medium, and valve is closed.In this application, non-return valve 13 is set It sets and is being set between the water inlet pipe 2 and outlet pipe 3 being located inside the tap main body, it is possible thereby to control by water inlet pipe 2 The water entered into tap main body 1.

In one embodiment, as shown in Fig. 2, the tap of the application further includes circlip 14, the circlip setting exists At the outlet end 15 of the tap main body, and it is located at the inside of the tap main body 1；The outlet pipe 3 passes through the card Spring 14.Fig. 3 and Fig. 4 shows the structure of circlip.In this application, circlip 14 is set on outlet pipe 3, the inner wall of the circlip 14 It is provided with the second protrusion 142, is provided with and second protrusion 142 at the water outlet pipe outer wall and the contact site of the circlip The second groove 32 matched, so that outlet pipe 3 can rotate in circlip 14.

In one embodiment, the outlet end inner wall of the tap main body is provided with the first groove 151, and described first Groove 151 can be engaged by clamping with the first protrusion 141 on the circlip outer wall.In one embodiment, it is arranged on circlip 14 There is cutting 143, the cutting 143 can be plugged into the socket 113 in the tap main body.

When assembling the tap of the application, circlip 14 is set on outlet pipe 3, the second protrusion 142 of circlip 14 is made It is matched with the second groove 32 of outlet pipe, then the cutting of circlip 143 is adjusted to towards the socket 113 in main body, will be gone out Water pipe 3 is inserted into main body water outlet, until the first protrusion 141 on circlip eventually enters into the first groove 151 in main body, cutting 143 enter socket 113.The effect that first protrusion 141 enters the first groove 151 is to keep circlip and outlet pipe solid as a whole Due in main body, while can be rotated with the axle center of main body water outlet.The effect that cutting 143 enters socket 113 is to make be discharged Pipe will not be such that circlip also rotates with it when rotation.

In one embodiment, the lower part of tap main body is provided with pedestal 18 and rubber mat 19, to facilitate the application The fixation and installation of tap.

The tap of the application can be used for water purifier, and wherein water inlet pipe is connected with the treated water outlet of water purifier, use The processed purified water of water purifier is come from conveying to user.

It is understood to one skilled in the art that be also provided on the tap main body of the application water tap by Button, for controlling the opening and closing of tap.This switch button setting can according to the Conventional wisdom of this field come into Row, the application are no longer described in detail.

The major function of the application tap is that tap is made to keep the closed of leading water inlet pipe when not in use, is made in it The water and air exclusion in portion.Outlet pipe is set to be fixed in main body and can be rotated simultaneously.When not in use, the water flow of entire tap Water in channel is stationary, and non-return valve is closed, so that pure water and external environment between water purifier and faucet；And it is using When, the opened by pressure non-return valve of water flow, so that water is flowed by non-return valve toward water outlet.The application passes through in tap main body Non-return valve is set, tap is made to keep the closed of leading water inlet pipe, the water and air exclusion for keeping it internal when not in use.Do not make Used time, the water in the water stream channel of entire tap is stationary, and non-return valve is closed so that the pure water between water purifier and faucet with External environment；And when in use, the opened by pressure non-return valve of water flow, so that water is flowed by non-return valve toward water outlet.Meanwhile The setting of circlip makes outlet pipe be fixed in main body and can be rotated.
