Detailed Description

In order to specifically describe the embodiments and achieve the effects of the present application, an embodiment is provided and described below with reference to the drawings.

Referring to fig. 1 to 4, a water spraying unit 100 of a shower head device is shown, wherein the water spraying unit 100 is rotatably disposed on a base 200 of the shower head device and is mainly formed by assembling an adjusting base 10 and a mounting base 11 in a front-back corresponding manner. A plurality of nozzles are disposed between the adjusting base 10 and the mounting base 11, and the nozzles have respective water outlets and inlets between the adjusting base 10 and the mounting base 11, the mounting base 11 is connected to the water inlet 101 of the base 200 of the shower device, and the water inlet 101 is connected to a water source. Therefore, the relative rotation between the water spraying unit 100 and the base 200 of the shower device can make one of the nozzles communicate with the water inlet 101 of the base 200, so that the water from the water source flows through the water inlet 101 and the inside of the nozzle and then is sprayed out from the water outlet 102.

One of the nozzles has a rotary nozzle structure, which is composed of a housing 15, an axis 20, and a fluid guiding base 40. The housing 15 is generally tubular, the front end of the housing 15 is engaged with the inner wall of the adjusting seat 10, so that the water outlet end 102 of the housing 15 is positioned on the adjusting seat 10, the rear end of the housing 15 is connected to the mounting seat 11, so that the mounting seat 11 and the housing 15 define a chamber 17, and the inner space of the chamber 17 is long-column-shaped.

The guide seat 40 has a ring-shaped base 41 positioned at the rear opening of the housing 15 and the stopper 12 on the sidewall of the mounting seat 11, so that the guide seat 40 and the water inlet end at the bottom of the mounting seat 11 are spaced apart. In addition, the guide seat 40 has a central base 45 spaced apart from the annular base 41, a positioning column 47 protruding from the central base 45 toward the water outlet end 102, and a plurality of guide vanes 43 connecting the inner side wall of the annular base 41 and the outer side wall of the central base 45, the guide vanes 43 extending along the radial direction of the central base 45 and being tangent to the central base 45 at predetermined angles, and swirl openings 46 defined between adjacent guide vanes 43. In other words, the swirl openings 46 are arc-shaped and extend through opposite sides of the annular deflector 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 two ends. Wherein, a plurality of rectifying pieces 26 are disposed on the inner wall of the shaft core 20 and distributed in a cross shape and extend to the water inlet 21. The water outlet 22 of the shaft 20 has a spherical end 27 positioned at the water outlet 22 and communicated with the water outlet 102 of the adjusting seat 10, wherein the spherical end 27 and the water outlet 102 are complementary structures. In addition, the water inlet 21 of the shaft 20 is limited to the annular track between the inner wall of the chamber 17 and the positioning column 47 of the diversion seat 40, so that the shaft 20 is eccentrically arranged relative to the water outlet direction (i.e. the shaft is inclined backwards and outwards).

In this embodiment, the chamber 17 adjacent to the water outlet end 102 is a long column, and the inner wall of the chamber is provided with a plurality of protruding blocks 18 in an annular arrangement, such that the protruding blocks 18 form a guiding groove 19 therebetween, and the spherical end 27 of the shaft core 20 is provided with a plurality of stopping columns protruding radially as guiding members 28 and positioned in the guiding groove 19. In addition, the surface of the projection 18 has a slope to guide the surface of the shaft center 20, so that the shaft center 20 is disposed obliquely, and the water outlet end (spherical end 27, guide 28) of the shaft center 20 forms at least two annular positioning areas, and can stably perform a rotation motion, and simultaneously avoid the shaft center 20 from rotating, so that the water flow sprayed from the water outlet 22 of the shaft center 20 is a concentrated linear water flow, rather than a conical radial water flow sprayed due to the rotation of the shaft center in the prior art rotary nozzle.

It should be noted that the positioning post 47 of the diversion seat 40 is aligned with the water inlet 101 and the water outlet 102, and one end of the water inlet 21 of the shaft 20 is axially extended with a column 25 along the rear end of the rectifying plate 26 to be positioned on the outer peripheral wall of the positioning post 47, so as to stabilize the rotation track of the shaft 20.

When the water flow from the water source passes through the rotational flow opening 46 of the diversion seat 40 from the water inlet 101, the water flow generates a lateral water flow in the chamber 17 to drive the shaft 20 to rotate, and the water flow is communicated from the water inlet 21 of the shaft 20 to the water outlet 102 of the water spraying unit 100, and the rotating water flow is output through the rotating motion of the shaft 20.

Referring to fig. 5, another water spraying unit of a shower head is shown, in this embodiment, a cavity adjacent to the water inlet 101 is provided with an inclined surface to guide the surface behind the shaft center 20, the cavity adjacent to the water outlet 102 is substantially in a long column shape, three bumps 18 are convexly arranged on the inner wall at equal angles, a plurality of guide grooves are radially arranged at the water outlet of the shaft center 20 and are annularly arranged, and the guide grooves are used as a guide 28 to accommodate the bumps 18, so that the shaft center 20 is inclined and can stably rotate, and the rotation of the shaft center 20 is avoided.

In the embodiment, the number of the guiding elements 28 is an integral multiple of the number of the protrusions 18 to maintain the rotational balance, however, the number of the protrusions 18 may be only one to position the shaft center 20.

The above-described embodiments and/or implementations are only illustrative of the preferred embodiments and/or implementations for implementing the technology of the present application, and are not intended to limit the implementations of the technology of the present application in any way, and those skilled in the art can make many changes or modifications to the equivalent embodiments without departing from the scope of the technology disclosed in the present application, but should still be considered as the technology or implementations substantially the same as the present application.
