Namely, the outer shell 30 and the inner shell 31 are nested, and water is guided by the water guide pipes 36 with the number equal to the number of layers of the atomizing nozzles 35, so that when water is introduced into the water supply pipe 21, water sources sequentially enter the atomizing nozzles 35 at each layer along the plurality of water guide pipes 36, and water can be sprayed to each atomizing nozzle 35 only by a single water supply pipe 21.
On the basis of the above technical solution, in order to achieve the purpose of rotating the inner housing 31 to close the atomizing nozzle 35, referring to fig. 5 and 6, the sealing mechanism is an extrusion protrusion 37, a plurality of extrusion protrusions 37 are fixed on the surface of the inner housing 31, a plurality of extrusion protrusions 37 are located on the same vertical plane, and the number of extrusion protrusions 37 corresponds to the number of layers of the atomizing nozzle 35 one by one.
Namely, the extrusion protruding blocks 37 with the same layer number are arranged on the surface of the inner shell 31 and limit the extrusion protruding blocks 37 to be the same vertical plane, so that the surface can be based, when the inner shell 31 rotates, the extrusion protruding blocks 37 can pass through the water guide pipe 36, and because the water guide pipe 36 is in a one-way communication state with the water guide pipe 21, when the surface of the water guide pipe 36 is extruded, a water source cannot pass through, so that the road sections between the extrusion protruding blocks 37 and the water guide pipe 21 are all in a water-through state, and the atomizing nozzles 35 on the path where the extrusion protruding blocks 37 pass are separated from the passage, namely, the atomizing nozzles 35 on the path where the extrusion protruding blocks 37 pass through cannot spray water, so that the purpose of sealing the atomizing nozzles 35 on the path where the extrusion protruding blocks 37 pass through is achieved.
Example two
In the first embodiment, the sealing structure is configured to seal by moving on one side, and under the limitation of the structure, the sealing direction of the extrusion protrusion 37 is single, that is, the structure cannot pass water from the portion far away from the water pipe 21, but can only pass water on one side of the water pipe 21, and in some cases, the problem of inconvenient angle adjustment still exists, so as to solve the problem, please refer to fig. 7 and 8, specifically:
the shell body 30 is a hollow spherical shell body, the inner shell body 31 comprises a first connecting plate 311 and a second connecting plate 312, the first connecting plate 311 is fixed with the shaft sleeve 32, the second connecting plate 312 is fixed with the central shaft 33, the first connecting plate 311 and the second connecting plate 312 are arc-shaped plate bodies, a plurality of extrusion convex blocks 37 are arranged on the surfaces of the first connecting plate 311 and the second connecting plate 312, the number of the extrusion convex blocks 37 on the surfaces of the first connecting plate 311 and the second connecting plate 312 corresponds to the number of layers of the atomizing spray heads 35 one by one, the atomizing spray heads 35 on the surface of the shell body 30 are divided into two groups which are symmetrical based on hemispheres, each group of atomizing spray heads 35 is connected with water guide pipes 36 with the same number of layers of the atomizing spray heads 35, and the water guide pipes 21 are two, and each water guide pipe 21 is communicated with the water guide pipes 36 connected with one group of the atomizing spray heads 35.
That is, the inner shell 31 is not a circular shell, but is connected by two arc-shaped plates, the two arc-shaped plates rotate independently and are matched with two water delivery pipes 21, so that the original multiple layers of atomizing nozzles 35 are divided into two groups, each group of atomizing nozzles 35 independently deliver water through one water delivery pipe 21, and then independently rotate through the first connecting plate 311 or the second connecting plate 312 to control the extrusion convex blocks 37 at corresponding positions to extrude the corresponding water delivery pipes 36, so that the water delivery is carried out from two groups of structures, the adjustable range is larger, and the angle capable of spraying water is more.
Because in the above technical solution, the integral rotation is supported by the first connecting plate 311 and the second connecting plate 312, which may lead to the problem of bending of the structure, in order to solve this problem, the inner sides of the arc-shaped recesses of the first connecting plate 311 and the second connecting plate 312 are provided with the supporting frames 313, that is, the positions of the bending positions are limited by the supporting frames 313, so as to reduce the bending degree of the structure, the supporting frames 313 can be in a cross bar structure as shown in fig. 7 and 8, and can also be supported by a reticular supporting structure, the structure is not limited, and the arc-shaped recesses of the first connecting plate 311 and the second connecting plate 312 can be supported.
For the sake of convenience of understanding, fig. 8 is a schematic vertical sectional view of the outer casing in the second embodiment of the present invention, but only shows the state structure of the single-layer atomizer 35 in the interior, and the other multi-layer structure is the same as that shown, and only the number of atomizers 35 and the length of the water guide tube 36 are different, and therefore not shown.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
