Water outlet mouthpiece 25 is offered, the water outlet mouthpiece 25 and aforementioned 15 face of water outlet, water outlet connector 54 pass through water outlet mouthpiece 25 and goes out
The mouth of a river 15 is fixedly connected.
The synchronous switch spool 30 is mounted in the first installation cavity 11, former hotter water import 13, hot water flux 16, mixed water flow
Road 17, outlet passage 18 are communicated with port corresponding on synchronous switch spool 30 docking respectively, enable synchronous switch spool 30
Enough control the open and-shut mode at the mouth of a river and water flow passage that communicate therewith.The synchronous switch spool 30 is equipped with one point of water handle 31, uses
In the working condition of adjusting control synchronous switch spool 30, and then reach the mesh for controlling the opening and closing at each mouth of a river and water stream channel
's.
The thermostatic valve core 40 is mounted in the second installation cavity 12, for controlling the inflow of hot water or cold water, reaches adjusting
The effect of mixed water temperature.Aforementioned cooling water inlet 14, hot water flux 16 and mixed water flow passage 14 are corresponding on thermostatic valve core 40 respectively
Port docking communicates.The thermostatic valve core 40 is equipped with a temperature control handle 41, for adjusting control mixed water temperature.
The working principle that the present embodiment is described in detail is as follows:
Firstly, hot water connector 52 and cold water connector 53 are connect with external hot water pipeline and cold water pipes respectively.At the beginning,
Synchronous switch spool 30 and thermostatic valve core 40 are in closed state, at this point, being hindered between mixed water flow passage 17 and outlet passage 18
Break, and the hot water in external water route is blocked at hot water inlet 13 and cannot be introduced into hot water flux 16.
Then, water handle 31 is divided to regulate and control synchronous switch spool 30 by rotation, so that hot water inlet 13 and hot water flux 16
It communicates, external hot water is allowed to flow to thermostatic valve core 40.Then, by temperature control handle 41 regulate and control thermostatic valve core 40 so that hot water and
Cold water is able to enter in thermostatic valve core 40 by certain flow and mix, and mixed water is then flowed from thermostatic valve core 40
Out, and through overmulling water flow passage 17 synchronous switch spool 30 is flowed to.
Then, mixed water can flow into corresponding outlet passage 18 and from correspondence according to the state of synchronous switch spool 30
Water outlet 15 flow out.
Finally, closing synchronous switch spool 30 and thermostatic valve core 40 return to closed state.
The design focal point of the utility model is:
1, it by the synchronous switch spool at one control of setting each mouth of a river and runner opening and closing, may be implemented to intake to hot water
With the close synchronously of mixing water outlet, hot and cold water string water is avoided, therefore the cold and hot water inlet end of the utility model is without installing non-return additional
Valve.
2, the outlet passage of the utility model is setting up and down two, can carry out being lauched by synchronous switch spool
The switching on road.
3, outer housing is connected by cold and hot water swivel with interior main body, while forming cold and hot water inlet water route, is also limited
Interior main body is rotated around the axial direction of decorative shell;And abutting joint has the case ring interface at decorative shell both ends respectively
Case ring, and case ring is butted on the both ends of interior main body respectively, therefore, can limit to the interior main body in decorative shell, prevents
Only interior main body is shaken;The design of such structure has the advantages that manufacture and simple to install, at low cost, avoid tradition integrally at
The high problem of type structure manufacturing cost.
4, by being convexly equipped with positioning rib on the outer wall of interior main body, and the inner wall of positioning rib and decorative shell offsets,
So that it is formed with the air gap between the inner wall of decorative shell and the outer surface of interior main body, it is outer to obstruct interior main body and decoration
The heat transmitting of shell, it is ensured that decorative shell is always ambient temperature, is played the role of anti-scald.
5, interior main body is made by using cast copper material, compared to traditional plastic material, the intensity and anti-freezing of interior main body
Performance is more preferable, it is not easy to crack.
