Compared with the existing techniques, the technical solution of the present invention has the following beneficial effects.

1. The present invention provides a water outlet device in which the inner sidewalls of the plurality of water outflow passages are tapered. When a radial dimension of each of the inner sidewalls of the plurality of water outflow passages gradually becomes smaller in a direction of the water flow, the water spray pattern of the water flow has a more concentrated range and a stronger impact force. When the radial dimension of each of the inner sidewalls of the plurality of water outflow passages gradually becomes larger in the direction of the water flow, the water spray pattern of the water flow has a larger range and a weaker impact force.

2. The present invention provides a water outlet device, each of the at least one injector comprises at least one injection hole, a water outflow direction of the at least one injection hole, and an axial direction of a corresponding one of the plurality of water outflow passages forms an angle a. As the angle a becomes larger, a collision between water flowing out from the at least one injection hole and inner sidewalls of the corresponding one of the plurality of water outflow passages becomes more obvious, an atomization effect of water spray pattern of the water flow becomes better, and an energy loss of the water flow becomes larger, so that an impact force of the water flow is decreased. When the angle a becomes smaller, the collision becomes less obvious, or water directly flows out without impacting the inner sidewalls, the atomization effect of the water spray pattern of the water flow becomes weaker, and an energy loss of the water flow becomes smaller, so that the impact force of the water flow is significantly enhanced.

3. The present invention provides a water outlet device, according to the aforementioned characteristics, in which a plurality of injection holes are defined by each of the at least one injector. At a surface of the at least one injector facing the corresponding one of the plurality of water outflow passages, centers of the plurality of injection holes can be arranged at different radial distances relative to a central axis of the at least one injector. When a larger impact force of the water is needed, a large number of the injection holes with a small angle can be disposed close to the central axis of the injector. When a larger outflow range is needed, a large number of injection holes with a large angle can be disposed further away from the central axis of the injector.

Therefore, the water outlet device provided by the present invention can freely adjust water spray patterns with various dispersed ranges, water outflow forms, and impact forces according to the adjustment of the angle a between the water outflow direction of the at least one injection hole and the axial direction of the corresponding one of the plurality of water outflow passages, an arrangement of the injection holes in a radial direction of the injector, and a taper β of the inner sidewalls of the plurality of water outflow passages, without making big adjustments to an overall structure of the water outlet device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The present invention will be further described below with the combination of the accompanying drawings together with the embodiments.

Referring toFIGS. 1-7, the water outlet device comprises at least one rotatable driving member1, at least one injector2, and a main body3with a plurality of water outflow passages31.

The main body3comprises at least one accommodating cavity32. Each of the at least one accommodating cavity32is connected to a corresponding one of the plurality of water outflow passages31, and each of the at least one accommodating cavity32is disposed above the corresponding one of plurality of water outflow passages31. Each of the at least one rotatable driving member1and a corresponding one of the at least one injector2are respectively disposed in a corresponding one of the at least one accommodating cavity32. Each of the at least one rotatable driving member1is driven to rotate by water flow, and each of the at least one injector2is driven to rotate in the corresponding one of the at least one accommodating cavity32by a corresponding one of the at least one rotatable driving member1.

Each of the at least one injector2comprises at least one injection hole21. Each of the at least one injection hole21is connected to the corresponding one of the plurality of water outflow passages31. A water outflow direction of the at least one injection hole21and an axial direction of a corresponding one of the plurality of water outflow passages31forms an angle a. As the angle a becomes larger, a collision between water flowing out from the at least one injection hole21and inner sidewalls of the corresponding one of the plurality of water outflow passages31becomes more obvious. As the collision becomes more obvious, an atomization effect of a water spray pattern of the water flow becomes better and an energy loss of the water flow becomes larger, so that an impact force of the water flow decreases. As the collision becomes less obvious, the atomization effect of the water spray pattern of the water flow becomes weaker and an energy loss of the water flow becomes smaller, so that the impact force of the water flow increases. Therefore, it is possible to select an appropriate angle of the angle a that is suitable for different types of showers.

The inner sidewalls of the plurality of water outflow passages31are tapered, and the tapered inner sidewalls can be designed in two ways. As a radial dimension of each of the inner sidewalls of the plurality of water outflow passages31gradually becomes smaller in a direction of the water flow (e.g., an upper portion of the inner sidewalls is larger than a lower portion of the inner sidewalls in the direction of the water flow), the water spray pattern of the water flow has a more concentrated range and a stronger impact force. As the radial dimension of each of the inner sidewalls of the plurality of water outflow passages31gradually becomes larger in the direction of the water flow (e.g., a lower portion of the inner sidewalls is larger than an upper portion of the inner sidewalls in the direction of the water flow), the water spray pattern of the water flow has a larger range and a weaker impact force. In this embodiment, due to the tapered inner sidewalls, the radial dimension of each of the inner sidewalls of the plurality of water outflow passages31in the direction of the water flow gradually becomes larger. In practical use, it is also possible to find a balance between the range and the impact force suitable for different types of showers.

Further, when water flows out from the plurality of water outflow passages31, external air also enters the plurality of water outflow passages31to be mixed with the water, so that the water flow further forms an aerated water flow.

Specifically, in order to achieve the angle a between the water outflow direction of the at least one injection hole21and the axial direction of the plurality of water outflow passages31, in a cross-sectional view of each of the at least one injection hole21in the axial direction of the corresponding one of the plurality of water outflow passages31, a first sidewall of each of the at least one injection hole21adjacent to a central axis of the injector2is sloped relative to the axial direction of the corresponding one of the plurality of water outflow passages, a second sidewall of each of the at least one injection hole21away from the central axis of the injector2is parallel to the axial direction of the corresponding one of the plurality of water outflow passages31.

Each of the inner sidewalls of the plurality of water outflow passages31is disposed with a plurality of regulating strips311. The plurality of regulating strips311extend in a length direction of each of the inner sidewalls (i.e., extend in the direction of the water flow), and the plurality of regulating strips311are disposed along a circumference of each of the inner sidewalls at intervals. The regulating strips311help to regulate the water flow in the plurality of water outflow passages31to mitigate turbulence, so that the water spray pattern can achieve a desired effect.

In this embodiment, the rotatable driving member1is an impeller, the main body3comprises at least one water oblique inlet on a first side away from the plurality of water outflow passages31, and water flowing from the at least one water oblique inlet impacts the impeller and drives the impeller to rotate.

To link the impeller and the injector2so that the impeller can drive the injector2, a first side of the impeller adjacent to the injector2extends outwardly to form an insert bar in a direction of a central axis of the impeller, and the injector2comprises an insert hole for coupling with the insert bar.

In the aforementioned water outlet device, the water spray pattern is atomized water with relative obvious atomized effect, low impact force, and a larger dispersed range.

Referring toFIG. 8andFIG. 9, the difference between this embodiment and Embodiment 1 is that, at a surface of the at least one injector2facing the corresponding one of the plurality of water outflow passages31, a center of a first injection hole21(to the right inFIG. 8andFIG. 9) is spaced a first distance from a central axis of the injector2and a center of a second injection hole21(to the left inFIG. 8andFIG. 9) is spaced a second distance from the central axis of the injector2and the angle a between a water outflow direction of the first injection hole21and the axial direction of the corresponding one of the plurality of water outflow passages31is different than the angle a between a water outflow direction of the second injection hole21and the axial direction of the corresponding one of the plurality of water outflow passages31.

This embodiment comprises injection holes at two different radial positions relative to the central axis. The angle a between the water outflow direction of the first injection hole21closer to the central axis and the axial direction of the corresponding one of the plurality of water outflow passages31is smaller than the angle a between the water outflow direction of the second injection hole21further away from the central axis and the axial direction of the corresponding one of the plurality of water outflow passages31.

Therefore, the water from the first injection hole21has a strong impact force and a relatively weak atomization effect, so that the water outlet device of this embodiment achieves a mixed water outflow effect of two water flows. In the two water flows, if one of the two water flows is to be strengthened, additional injection holes21can be added that are approximately the same radial distance away from the central axis of the injector2as the first injection hole21or as the second injection hole21.

Referring toFIG. 10, the difference between this embodiment and Embodiment 1 is that the radial dimension of each of the inner sidewalls of the plurality of outflow passages31gradually becomes smaller in the direction of water flow, thereby forming a water spray pattern with more concentrated water flow and stronger impact force relative to the water flow and impact force of the water spray pattern formed by Embodiment 1.

Referring toFIG. 11, the difference between this embodiment and Embodiment 2 is that the radial dimension of each of the inner sidewalls of the plurality of outflow passages31gradually becomes smaller in the direction of water flow, thereby forming a water spray pattern with more concentrated water flow and stronger impact force relative to the water flow and impact force of the water spray pattern formed by Embodiment 2.

Therefore, the water outlet device provided by the present invention can freely adjust water spray patterns with various dispersed ranges, water outflow forms, and impact forces according to the adjustment of the angle a between the water outflow direction of the at least one injection hole21and the axial direction of the corresponding one of the plurality of water outflow passages31, a radial spacing or distance between a central axis of the injector2and the at least one injection hole21, and a taper β of the inner sidewalls of the plurality of water outflow passages31, without making big adjustments to an overall structure of the water outlet device.

Referring toFIGS. 12-13, the difference between this embodiment and Embodiment 1 is that in the cross-sectional view of each of the at least one injection hole21in the axial direction of the corresponding one of the plurality of water outflow passages31, a first sidewall of each of the at least one injection hole21adjacent to a central axis of the injector2is sloped relative to the axial direction of the corresponding one of the plurality of water outflow passages31, a second sidewall of each of the at least one injection hole21away from the central axis of the injector2is also sloped relative to the axial direction of the corresponding one of the plurality of water outflow passages31, and an angle γ1between the second sidewall and the axial direction of the plurality of water outflow passages31is smaller than an angle γ2between the first sidewall and the axial direction of the plurality of water outflow passages31, so that this embodiment can achieve an effect similar to that of Embodiment 1, in which the second sidewall of each of the at least one injection hole21is parallel to the axial direction of the plurality of water outflow passages31.

The above description is only a preferred embodiment of the present disclosure, and the scope of the present disclosure is not limited in this embodiment. That is, equivalent changes and modifications made in the scope of the disclosure and the specification contents should remain within the scope of the present disclosure.
