In the figure: 10. a first joint; 11. a first inlet; 12. a first outlet; 13. buckling; 20. a second joint; 21. a second inlet; 22. a second outlet; 23. a bayonet; 24. and (4) external threads.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1, 2 and 3, the overflow head structure includes a first joint 10 and a second joint 20, a first flow passage is formed inside the first joint 10, and a second flow passage is formed inside the second joint 20. Specifically, one end of the first joint 10 is provided with a first inlet 11, and the other end of the first joint 10 is provided with a first outlet 12. A second inlet 21 is provided at one end of the second joint 20, and one end of the second joint 20 is formed as a second outlet 22. Detachably fixing an end of the first joint 10 adjacent to the first outlet 12 and an end of the second joint 20 adjacent to the second inlet 21 so that the first outlet 12 communicates with the first inlet 11; the aperture of the first inlet 11 is larger than the aperture of the second outlet 22.

On the basis of the structure, use the utility model discloses a during overflow head structure, can insert the play water department of hydrophone under the first import 11 of first joint 10, the second export 22 and the outside outlet conduit of second joint 20 are connected, then first export 12 of first joint 10 and the second import 21 of second joint 20 connect can, the water of hydrophone can get into first runner through first import 11, the water in the first runner gets into second import 21 through first export 12, the second runner is introduced with water to second import 21, the water of second runner is exported 22 through the second afterwards, because the bore of first import 11 is greater than the bore of second export 22, the macrostoma is intake, the osculum goes out water, increase the inflow, and easy dismounting.

Specifically, in order to facilitate the detachment and installation of the first joint 10 and the second joint 20, a buckle 13 may be disposed on an outer surface of an end portion of the first joint 10 close to the first outlet 12, and a bayonet 23 is correspondingly disposed on an end portion of the second joint 20 close to the second inlet 21, when the first joint 10 is assembled, the end portion of the first joint 10 close to the first outlet 12 is inserted into an end portion of the second joint 20 close to the second inlet 21, so that the buckle 13 is clamped into the bayonet 23, that is, the first joint 10 and the second joint 20 may be fixed in an insertion manner, and meanwhile, the connection structure is more stable by matching the clamping of the buckle 13 and the bayonet 23.

More specifically, a sealing ring can be clamped between the outer surface of the end portion of the first joint 10 close to the first outlet 12 and the inner surface of the end portion of the second joint 20 close to the second inlet 21, so that the joint of the first joint 10 and the second joint 20 is in sealing engagement, the sealing performance is better, and water leakage is prevented.

Preferably, in this embodiment, the inner diameter of the second flow passage gradually decreases from the end near the second inlet 21 to the end near the second outlet 22, and the water flow entering the second flow passage can form a certain water pressure at the second outlet 22 to increase the flow rate of the water flow.

Furthermore, the section of the second flow channel in the water flow direction is in an inverted cone shape, namely, the inner space of the second flow channel is in the inverted cone shape, so that the water pressure at the water outlet position is increased, and the overflow flow speed is increased.

Of course, the second flow channel may also be provided with an inclined surface inclined inward from top to bottom, and the above-mentioned structure with a wide top and a narrow bottom may also be formed.

Preferably, the outer surface of the end of the second connector 20 adjacent to the second outlet 22 is provided with external threads 24 to facilitate the threaded connection of the second connector 20 to an external pipe.

Preferably, the first inlet 11 is square, and the square structure has a larger area, so that the caliber of the first inlet 11 is relatively larger, and the water inflow is increased.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
