Preferably, the upper cap 1, the lower cap 2, the wire mesh tube 3 and the thread distributor 4 are made of stainless steel.
The components of the water cap structure are specifically described as follows:
the upper cap 1 and the lower cap 2 have a substantially disc-shaped structure, and the upper cap 1 and the lower cap 2 are held in correspondence with each other. And the opposite end surfaces of the upper cap 1 and the lower cap 2 are protruded along the circumferential direction to form a blocking ring, so as to form a limiting blocking effect on a silk screen arranged between the upper cap 1 and the lower cap 2.
A through hole is provided in the center of the lower cap 2. The thread distributor 4 penetrates through the lower cap 2 from the central through hole of the lower cap 2, extends to the upper cap 1 and is fixedly connected to the center of one end face of the upper cap 1. The thread distributor 4 is arranged concentrically and vertically with the upper cap 1 and the lower cap 2.
The thread distributor 4 includes a thread distribution pipe 41, a lower end connection pipe 42, a water distribution pipe 43, and an upper end connection pipe 44, which are integrally connected in this order from bottom to top. The thread distributor 4 can be manufactured by integral injection molding.
Wherein: the thread distributing pipe 41 is provided with threads. The threaded distribution pipe 41 cooperates with the nut to effect the connection of the water cap to the distribution plate.
The lower connecting pipe 42 is fixedly connected with the lower cap 2.
The water distribution pipe 43 is positioned in the wire mesh pipe 3, and a plurality of water distribution holes are arranged on the periphery of the water distribution pipe 43. Preferably, the water distribution holes are elliptical. The water flow is filtered from the thread distributor 4 to the wire mesh tube 3 by the water distribution holes.

And, the top end of the upper end connecting pipe 44 is uniformly provided with a plurality of protrusions 8 along the circumferential direction thereof; a plurality of grooves 9 corresponding to the protrusions 8 are formed in the end face of one end of the upper cap 1, which is connected with the upper connecting pipe 44; the upper connecting tube 44 and the upper cap 1 are fixed by the protrusion 8 and the groove 9.
The filter screen is positioned between the upper cap 1 and the lower cap 2, the upper cap 1 and the lower cap 2 limit the position of the filter screen, and the thread distributor 4 is positioned at the inner side of the filter screen net 3.
That is, the diameter size is: upper cap 1 = lower cap 2 > wire mesh tube 3 > thread distributor 4.
The wire mesh tube 3 comprises a tubular structure surrounded by wedge wire mesh and an inner support rod for supporting the wedge wire mesh tube 3. The supporting rods are uniformly distributed on the inner side of the silk screen.
The cross section of the silk screen is in an isosceles triangle structure. So that the channels formed between the screens are represented as isosceles trapezoid channels and the channels are represented as large inside and small outside. And, sharp angles on the silk screen are dulled. So that the whole silk screen pipe 3 is burr-free and the smoothness of water flow is ensured.
In operation, water enters through the thread distributing pipe 41 on the thread distributor 4, passes through the lower connecting pipe 42 to the water distributing pipe 43 and flows out from the water distributing hole, thus entering the silk screen pipe 3, and is discharged after being filtered by the silk screen pipe 3, so as to realize the filtering function. In addition, a plurality of water caps are uniformly distributed on the distribution plate, and the water flow distribution function can be realized.
In the present application, the connection stability between the upper cap 1 and the lower cap 2 is maintained for a long period of time without easy detachment. In the present applicant, the stopper 6 is tightly matched with the stopper hole 5 to fix the lower cap 2 on the thread distributor 4. Specifically, the end face of one end of the lower cap 2 facing away from the upper cap 1 is provided with a plurality of limiting holes 5 by taking the center of the end face as the center of the end face and the outer diameter of the thread distributor 4 as the diameter, and the periphery of the thread distributor 4 is provided with a plurality of limiting blocks 6 corresponding to the limiting holes 5. Preferably, three or six limiting blocks 6 and limiting holes 5 are arranged, and each limiting block 6 and each limiting hole 5 are in one-to-one correspondence in the vertical direction. The thickness of the limiting block 6 is the same as that of the limiting hole 5, so that after the limiting block 6 is buckled in the limiting hole 5, the outer surface of the limiting block 6 and the bottom end surface of the lower cap 2 are positioned on the same plane.
And the stopper 6 has a structure including, but not limited to, a rectangular, triangular, and trapezoidal block structure.
When the water cap is assembled, the lower cap 2 is assembled from the direction of the upper connecting pipe 44 of the thread distributor 4, the limiting block 6 is embedded in the limiting hole 5, the silk screen pipe 3 and the upper cap 1 are assembled, and finally the gasket 7 is assembled from the direction of the thread distributor 41, so that the whole water cap structure can be assembled.
In addition, in order to further improve the connection stability between the upper cap 1, the lower cap 2 and the screw distributor 4, the upper end connection pipe 44 may be welded to the upper cap 1 and the lower end connection pipe 42 may be welded to the lower cap 2 on the basis of the above. The welding point is at the junction of the convex point and the groove 9 and the junction of the limiting block 6 and the limiting hole 5.
Because the connection between the upper cap 1 and the thread distributor 4 is realized by the convex points and the grooves 9, and the connection between the lower cap 2 and the thread distributor 4 is realized by the limiting blocks 6 and the limiting holes 5, the upper cap 1, the lower cap 2 and the thread distributor 4 can not fall off easily even under the condition of oxidation of welding parts caused by long-term use.
The gasket 7 is sleeved outside the thread distributor 4 and is located below the lower cap 2, and since the limiting block 6 does not protrude out of the surface of the lower cap 2 after the upper cap 1 and the thread distributor 4 are assembled, that is, the gasket 7 can be tightly attached to seal the lower cap 2 for sealing the joint of the thread distributor 4 and the lower cap 2, so that the overall tightness of the water cap is ensured during operation.
When the water cap is integrally installed on the distribution plate, a plurality of installation holes are preset on the distribution plate, the threaded distribution pipe 41 on the water cap is inserted into the installation holes on the distribution plate, and the water cap is reliably clamped by the nut matched with the distribution plate by screwing the nut onto the threaded distribution pipe 41 of the threaded distributor 4.
The whole water cap structure, the upper cap 1 and the lower cap 2 are connected with the thread distributor 4 by adopting double fixing structures, the upper cap 1 and the lower cap 2 are firmly assembled and are not easy to loosen and fall off, the condition that the water cap falls off due to oxidization when the service time is too long is avoided, the service time of the water cap structure is prolonged, and the cost is saved.
The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
