Detailed ways

The following is a specific description of the embodiments of the present application and the achieved effects, and an example is provided and described with the drawings as follows.

Please refer to FIG. 1 to FIG. 4 , which illustrate a sprinkler unit 100 of a shower sprinkler device. The sprinkler unit 100 is rotatably disposed on the base 200 of the sprinkler sprinkler device, and is mainly composed of an adjustment seat 10 and an installation seat 11 The front and rear are assembled correspondingly. A plurality of spray heads are arranged between the adjustment seat 10 and the installation seat 11, and these spray heads have individual water outlet ends and water inlet ends between the adjustment seat 10 and the installation seat 11, and the installation seat 11 communicates with the base 200 of the shower sprinkler. The water inlet end 101 is connected to a water source. Therefore, the relative rotation between the sprinkler unit 100 and the base 200 of the shower sprinkler device can make one of the sprinkler heads communicate with the water inlet end 101 of the base 200, so that the water from the water source flows through the water inlet end 101 and the inside of the sprinkler head. Then it is sprayed out from the water outlet 102 .

One of the nozzles has a rotating nozzle structure, and the rotating nozzle structure is composed of a casing 15 , a shaft center 20 , and a guide seat 40 . The casing 15 is generally tubular, the front end of the casing 15 is engaged with the inner wall of the adjusting seat 10, so that the water outlet end 102 of the casing 15 is positioned on the adjusting seat 10, and the rear end of the casing 15 is connected to the mounting seat 11, so that the The mounting base 11 and the housing 15 together define a cavity 17 , and the inner space of the cavity 17 is a long column.

The guide seat 40 has an annular base 41 positioned at the rear end opening of the casing 15 and the block 12 on the side wall of the mounting seat 11 , so that the guide seat 40 and the water inlet end of the bottom of the mounting seat 11 are spaced apart. In addition, the guide seat 40 has a central base 45 spaced from the annular base 41 , a positioning post 47 protrudes from the central base 45 and faces the direction of the water outlet 102 , and a plurality of guide fins 43 are connected to the inner side wall of the annular base 41 With the outer side wall of the center base 45 , the guide vanes 43 extend along the radial direction of the center base 45 and are respectively tangent to the center base 45 by a predetermined angle, and a swirl opening 46 is defined between the adjacent guide vanes 43 . . In other words, the swirl opening 46 is arc-shaped and penetrates two opposite sides of the annular flow guide seat 40 .

The shaft 20 is accommodated in the chamber 17 and has a hollow cylindrical shape with a water inlet 21 and a water outlet 22 at both ends. The inner wall of the shaft center 20 is provided with a plurality of fairing pieces 26 distributed in a cross and extending to the water inlet 21 . The water outlet 22 of the shaft 20 is provided with a spherical end 27 positioned at the water outlet 22 and communicated with the water outlet 102 of the adjustment base 10 . The spherical end 27 and the water outlet 102 are complementary structures that match. In addition, the water inlet 21 of the shaft center 20 is limited to the annular track between the inner wall of the chamber 17 and the positioning column 47 of the guide seat 40, so that the shaft center 20 is eccentrically arranged with respect to the water outlet direction (that is, the shaft center faces backwards outside tilt).

In this embodiment, the chamber 17 adjacent to the water outlet 102 has a slightly long column shape, and the inner wall is protruded with a plurality of protrusions 18 arranged in a ring shape, so that a guide groove 19 is formed between the protrusions 18, and the spherical end of the shaft 20 is formed. 27 is radially protruded with a plurality of stop posts as guides 28 and positioned in the guide grooves 19 . In addition, the surface of the bump 18 also has an inclined surface to guide the surface of the shaft center 20, so that the shaft center 20 is inclined, and the water outlet end (the spherical end 27, the guide member 28) of the shaft center 20 forms at least two annular positioning area, and can stably perform rotational motion, while avoiding the rotation of the shaft 20, so that the water flow from the water outlet 22 of the shaft 20 is a concentrated linear water flow, rather than the rotation of the shaft in the prior art. A conical jet of water is ejected.

It is worth mentioning that the positioning column 47 of the guide seat 40 is in a straight line with the water inlet end 101 and the water outlet end 102 , and one end of the water inlet 21 of the shaft center 20 axially extends along the rear end of the fairing 26 with a cylinder 25 . , so as to be positioned on the outer peripheral wall of the positioning column 47 to stabilize the rotational trajectory of the shaft center 20 .

When the water flow from the water source passes through the swirl opening 46 of the guide seat 40 from the water inlet end 101, the water flow will generate a lateral water flow in the chamber 17 to drive the shaft 20 to rotate, and the water flow will be communicated from the water inlet 21 of the shaft 20 to the The water outlet 102 of the water spray unit 100 outputs a rotating water flow through the rotational movement of the shaft 20 .

Please refer to FIG. 5 , which shows a water spray unit of another shower sprinkler. In this embodiment, the chamber adjacent to the water inlet end 101 is provided with a slope to guide the surface behind the shaft 20 , and the chamber adjacent to the water outlet end 102 is provided with a slope. The chamber is in the shape of a long column, and the inner wall is protruded with three protrusions 18 arranged at equal angles. The outlet of the shaft 20 is provided with a plurality of guide grooves arranged in a ring shape. The guide grooves serve as a guide 28 to accommodate the protrusions 18. Therefore, the shaft center 20 is inclined and can rotate stably while avoiding the rotation of the shaft center 20 .

In this embodiment, the number of the guides 28 is an integer multiple of the number of the bumps 18 to maintain the rotational balance.

The above-mentioned embodiments and/or implementations are only used to illustrate the preferred embodiments and/or implementations of the technology of the present application, and are not intended to limit the implementation of the technology of the present application in any form. Personnel, without departing from the scope of the technical means disclosed in the content of this application, may make some changes or modifications to other equivalent embodiments, but they should still be regarded as substantially the same technology or embodiment as this application.
