Description

Technical Field

[0001] This invention belongs to the technical field of bathroom fixtures, specifically relating to a water outlet device and a shower head. Background Technology

[0002] As people's living standards improve, existing shower heads with a single static jet of water can no longer meet the needs of daily showering. More and more massage products that can produce dynamic water sprays are appearing on the market. These products generally achieve the effect of dynamic rotating water spray by rotating the water nozzle and using the angled jet holes on the nozzle. However, due to the limited number and shape of the jet holes, the dynamic water spray effect of these products is relatively simple, and the water sprays from multiple nozzles are not synchronized, making the overall water spray effect appear messy and disorderly, affecting the visual experience. Moreover, the massage effect is generally average. Summary of the Invention

[0003] In view of the technical problems of existing technologies, such as monotonous dynamic water output, disordered water spray, and mediocre massage effect, this invention proposes a water output device and shower head to solve the above-mentioned technical problems.

[0004] According to a first aspect of the present invention, a water outlet device is provided, comprising:

[0005] The main body is equipped with a water inlet and a water outlet.

[0006] The drive unit is rotatably disposed inside the main body;

[0007] The water outlet is rotatably disposed at the water outlet of the main body. The water outlet is provided with one or more water outlet holes, which are inclined relative to the rotation axis of the water outlet.

[0008] The water inlet on the main body impacts the drive unit to rotate, and the drive unit drives the outlet unit to rotate. The outlet unit has one or more outlet holes configured to satisfy the following conditions:

[0009] The mounting surface of the water outlet is a plane that passes through the axis of one or more water outlet holes and is perpendicular to the plane of rotation. Any two adjacent mounting surfaces of the water outlets are parallel to each other or at an angle of 360° / N, where N is the number of water outlets. Through the ingenious design of the water outlet holes, this water outlet device can achieve more diverse dynamic water flow effects than a single water outlet, thus providing a more varied massage experience.

[0010] Preferably, the device includes multiple water outlet sections, each with three water outlet holes. The three water outlet holes are tilted in the same direction and arranged in a triangle. The mounting surface is the plane containing the center line of the triangle, and the mounting surfaces of any two adjacent water outlet sections form a 360° / N angle. This arrangement allows the three water outlet holes to generate dynamic water splashes that do not interfere with each other when the water outlet sections rotate, resulting in a more aesthetically pleasing water splash pattern. Furthermore, the multiple water outlet holes provide a more diverse massage experience.

[0011] Further preferably, a positioning protrusion is provided on the upper part of the water outlet, the positioning protrusion is located on the extension line of the center line, and the included angle between any two adjacent water outlets is the angle formed in the direction of the positioning protrusion. The setting of this positioning protrusion facilitates the uniform control of the installation angle of the water outlet.

[0012] Preferably, the system includes multiple water outlet sections, each with two water outlet holes. The two water outlet holes are inclined in opposite directions and their directions on the upper and lower ends of the water outlet section are opposite to each other. The axes of the two water outlet holes are in the same plane, and the planes of the water outlet holes on any adjacent water outlet sections remain parallel. This configuration allows two spiral dynamic water splashes to be formed on a single water outlet section, and the parallel planes of the water outlet holes across multiple water outlet sections ensure that the water splash patterns of all water outlet sections remain consistent.

[0013] A further preferred embodiment includes a top cover and a front cover, which are sealed together. The top cover has a water inlet, and the front cover has one or more water outlets. This design facilitates installation and allows for the placement of corresponding internal components between the top cover and the front cover.

[0014] In a further preferred embodiment, the drive unit includes an inclined water body and a rotating mechanism. The rotating mechanism includes a rotor with an impeller mounted on it. The inclined water body mates with the inner top surface of the upper cover, forming a cavity at the mating point that communicates with the water inlet. The inclined water body has inclined water holes that communicate with the cavity and point towards the impeller. This configuration allows water flow to drive the impeller to rotate through the inclined water holes.

[0015] A further preferred embodiment has a central column located in the center of the inner cavity of the cover, and the rotating mechanism is rotatably mounted on the central column. This arrangement ensures stable assembly of the inclined water body, thereby guaranteeing smooth rotation of the impeller.

[0016] In a further preferred embodiment, the rotating mechanism also includes a speed reduction device, which comprises a speed reduction disc with an external gear and an internal gear correspondingly disposed on the inner surface of the cover. The speed reduction disc has a size smaller than the inner diameter of the cover, and the difference in the number of teeth between the external and internal gears is provided. This arrangement enables the rapid rotational motion of the impeller to be reduced to the required rotational speed for driving the water outlet section.

[0017] In a further preferred embodiment, the rotor is equipped with an eccentric wheel, which cooperates with a reduction gear and drives the reduction gear to rotate at a differential speed on the internal gear of the cover. This configuration enables the reduction gear to rotate at a differential speed in conjunction with the internal gear of the cover.

[0018] In a further preferred embodiment, the upper circumferential surface of the water outlet is provided with driving teeth, and the lower circumferential surface is provided with a sealing ring that rotates and seals with the water outlet. This arrangement allows for direct driving of the water outlet to rotate while also providing excellent rotational sealing.

[0019] In a further preferred embodiment, the drive unit also includes a turntable with drive teeth that mesh with the drive teeth. The reduction gear has multiple drive posts, and the turntable has redundant holes that mate with the drive posts. The size of the redundant holes is larger than the diameter of the drive posts, allowing the reduction gear to rotate around the central post while following the eccentric wheel in differential gear reduction. This turntable structure converts the eccentric rotation of the reduction gear into rotational motion around the central post, thereby stably driving the water outlet section to rotate.

[0020] Furthermore, the surfaces of the speed reducer and turntable are provided with a perforated structure to form a water outlet channel between the inclined water body and the outlet section. This perforated structure allows for the formation of internal water flow channels, ensuring proper water output.

[0021] According to a second aspect of the present invention, a shower head is provided, comprising the water outlet device as described above. By providing the water outlet device to the shower head, the shower head can achieve a corresponding dynamic water outlet effect.

[0022] This invention provides a water outlet device that addresses the technical problems of existing water outlet structures, such as monotonous water flow, chaotic water spray, and poor massage effect. By defining the mounting surface of the water outlet section, a unified angle can be achieved during installation, ensuring synchronized dynamic water flow from multiple outlet sections and improving the overall visual appeal of the water spray. Furthermore, the various outlet structure configurations result in more diverse water flow effects and a better massage experience. Attached Figure Description

[0039] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description and are illustrated by specific illustrative embodiments in which the invention may be practiced. In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the invention. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the invention is defined by the appended claims.

[0040] This invention proposes a water outlet device. Figure 1 A schematic diagram of the overall structure of a water outlet device according to an embodiment of the present invention is shown. The main body of the water outlet device includes an upper cover 1 and a face cover 2. The upper cover 1 has a water inlet at the middle of its upper end, and the face cover 2 has multiple water outlets at its lower end. A water outlet portion 3 is rotatably provided at the water outlet of the face cover 2. The following is in conjunction with... Figure 2 The exploded view of a water outlet device according to a specific embodiment of the present invention is shown below for detailed description:

[0041] Both the top cover 1 and the front cover 2 are open cylindrical structures. Their openings mate to form a cavity. Specifically, the top cover 1 and the front cover 2 are fitted together via internal and external threads, and a sealing structure, such as a sealing ring or a sealing gasket, is provided at the mating point. Figure 3 The schematic diagram of the cover structure according to the first specific embodiment of the present invention is shown in the figure. An internal gear 21 is provided on the inner surface of the cover 2, a central column 22 is provided in the middle of the cover 2, and multiple receiving cavities 23 for accommodating the water outlet 3 are formed on the inner surface of the cover 2. A driving unit for driving the water outlet 3 to rotate is provided in the cavity structure formed by the upper cover 1 and the cover 2. In this embodiment, the driving unit specifically includes a turntable 4, a reduction gear 5, a rotor 6, and an inclined water body 7. The turntable 4, reduction gear 5, and rotor 6 are disposed in the cavity structure through the central column 22. The inclined water body 7, when the cover 2 and the upper cover 1 are engaged, is described below... Figures 4-6 The structure of each component in the drive unit is described in detail below:

[0042] In a specific embodiment, Figure 4 A schematic diagram of the structure of the inclined water body according to a first specific embodiment of the present invention is shown, as follows: Figure 4As shown, an annular groove (or arc-shaped groove) is formed on the upper surface of the inclined water body 7. The outer end face of the annular groove is flat, and the height of the inner end face is slightly lower than the outer end face. This arrangement allows water from the inlet of the upper cover 1 to flow from the inner end face to the groove when the inclined water body 7 mates with the inner top surface of the upper cover 1. Multiple inclined water holes 71 are provided inwards in the annular groove, pointing towards the impeller of the rotor 6. Water flows through the inclined water holes 71, driving the impeller 6 to rotate. In a preferred embodiment, the annular groove is divided into multiple arc-shaped grooves according to the number of inclined water holes 71. For example, in this embodiment, three inclined water holes 71 are provided, dividing the annular groove into three arc-shaped grooves. Each arc-shaped groove is not interconnected to ensure the smooth rotation of the impeller 6.

[0043] Figure 5 A schematic diagram of the rotor structure according to a first specific embodiment of the present invention is shown, as follows: Figure 5 As shown, the rotor 6 includes multiple impellers arranged in a circular pattern. When assembled, the inclined water holes 71 of the inclined water body 7 can be perpendicular to or at a certain angle to the surface of the impellers, so that the water flow through the inclined water holes 71 drives the impellers to rotate. An eccentric wheel 61 is also provided on the impeller 6. The axis of the eccentric wheel 61 is parallel to the rotation axis of the impeller 6, so that when the impeller 6 rotates, the eccentric wheel 61 rotates eccentrically relative to the impeller 6.

[0044] In a specific embodiment, the reduction disk 5 is sleeved on the eccentric wheel 61 to follow the eccentric wheel 61 in eccentric rotation. An external gear structure is provided on the circumferential surface of the reduction disk 5, which meshes with an internal gear structure on the inner circumferential surface of the cover 2. The size of the reduction disk 5 is smaller than the inner diameter of the cover 2, and the external gear of the reduction disk 5 and the internal gear of the cover 2 are configured with differential teeth, so that the eccentric wheel 61 of the impeller 6 drives the reduction disk 5 to achieve differential tooth reduction rotation. Multiple drive columns are provided on the lower surface of the reduction disk 5 to drive the turntable to rotate.

[0045] Figure 6 A schematic diagram of the structure of the turntable according to a first specific embodiment of the present invention is shown, as follows: Figure 6 As shown, the turntable 4 has multiple redundant holes 42 that mate with the drive column on the reduction gear 5. The size of the redundant holes 42 is slightly larger than the size of the drive column to ensure that the eccentric rotational motion of the reduction gear 5 can be converted into the rotational motion of the turntable 4 around the central column 22. A drive gear 41 is also provided in the middle of the bottom surface of the turntable 4, which is used to drive the water outlet 3 to rotate.

[0046] In a specific embodiment, the surfaces of the speed reducer 5 and the turntable 4 are provided with a hollow structure so that the water flow can enter the water outlet 3 through the hollow structure after the drive rotor 6 rotates, and be ejected from the water outlet hole of the water outlet 3.

[0047] Continue to refer to Figures 7a-7b , Figures 7a-7b A schematic diagram of the water outlet section according to a first specific embodiment of the present invention is shown, as follows: Figure 7a and 7b As shown, the upper part of the water outlet section 3 is provided with an external gear structure that meshes with the drive gear 41 of the turntable 4. The middle surface of the water outlet section 3 is provided with an annular groove for placing a sealing ring to ensure the sealing performance of the water outlet section 3 when it rotates in the receiving cavity 23. The water outlet section 3 is provided with a water outlet hole 32 inside. The axis of the water outlet hole 32 is inclined relative to the rotation axis of the water outlet section 3 so that the water flow ejected from the water outlet hole 32 when the water outlet section 3 rotates forms a spiral water discharge dynamic effect.

[0048] Figure 8 A schematic diagram illustrating the working principle of the water outlet device according to a first specific embodiment of the present invention is shown, as follows: Figure 8 As shown in the figure, combined with the specific structure in the figure above, the working principle of the water outlet device is as follows: the water flows into the water outlet device through the inlet of the upper cover 1, and impacts the rotor 6 through the inclined water hole of the inclined water body 7 to make the rotor 6 rotate. The speed reduction disk 5 achieves differential speed reduction rotation by engaging the outer teeth of the outer circumference with the corresponding inner teeth on the cover 2 and under the action of the eccentric wheel 61. The speed reduction disk 5 then drives the turntable 4 to rotate. The drive gear 41 on the turntable 4 meshes with the outer gears on multiple water outlet parts 3, thereby driving multiple water outlet parts to rotate synchronously. The water flows through the water outlet hole of the water outlet part to form a spiral dynamic water outlet effect.

[0049] In a specific embodiment, the arrangement of the water outlet and the water outlet holes thereon satisfies the following conditions: the mounting surface of the water outlet is a plane that passes through the axis of one or more water outlet holes of the water outlet and is perpendicular to the plane of rotation; any two adjacent mounting surfaces of the water outlet are arranged at an angle of 360° / N, where N is the number of water outlets. In this embodiment, the number of water outlets is set to 4, and the angle is 90°. Alternatively, the angle on the plane of rotation can be expressed as follows: the angle between the projection lines of the axes of the water outlet holes on adjacent water outlets onto the plane of rotation (the radial end face of the cover 2) is always 90 degrees. Figures 9a-9c Cross-sectional and perspective views of the water outlet device in two states according to a first specific embodiment of the present invention are shown, wherein, Figure 9a and Figure 9b The figures show a planar cross-section and a three-dimensional view of the same rotating state. In this state, the extension of the axis of the water outlet just passes through the axis of the central column. At this point, the mounting surface is actually... Figure 9a The plane containing the X and Y axes (represented as a straight line in this view) has an included angle of 90° between the mounting parts of two adjacent water outlets. Figure 9cThis diagram shows the state of the water outlet section after rotating 90 degrees, at which point the angle between the two mounting surfaces remains 90°. In other embodiments, the number of water outlet sections 3 can be set to other values, such as three or more, as long as the mounting surfaces of any two adjacent water outlet sections are set at an included angle of 360° / N, the technical effect of the present invention can still be achieved. Furthermore, a single water outlet section 3 can also have multiple water outlet holes; for example, three holes are shown below. Figures 10a-10c A cross-sectional and perspective view of a water outlet device according to a second specific embodiment of the present invention is shown, in which, as Figure 10a and 10b As shown, a single water outlet has three water outlets arranged in a triangle, with the axes of the three water outlets tilting in the same direction. The mounting surface is the plane containing the center line of the triangle, and also satisfies the condition that the mounting surfaces of any two adjacent water outlets form an angle of 360° / N. That is, on the cross-section of the rotation plane (the radial end face of the cover 2), the angle between the center lines of the water outlets on adjacent water outlets (considering the three water outlets as the center lines of the overall triangle) is always 360° / N, where N is the number of water outlets. To facilitate assembly, a positioning protrusion can be provided on the water outlet, located on the extension line of the center line of the water outlet, so as to uniformly arrange the angles of multiple water outlets during assembly. The 360° / N angle direction is the angle between the center line of the water outlet and the direction of the positioning protrusion. Furthermore, in this embodiment, as... Figure 10c As shown in the cross-sectional view, both the water outlet 3 and its receiving cavity 23 are tapered curved surface structures, forming a dynamic fit. This structure can also be applied to the fit structure of the water outlet and the receiving cavity in the aforementioned embodiments. In this embodiment, the sealing ring structure in the above embodiments can also be used, which can also achieve the technical effect of the present invention.

[0050] In another embodiment, the multiple water outlets on the water outlet section can also be configured in other forms. The water outlets of the water outlet section satisfy the following conditions: the mounting surfaces of any two adjacent water outlet sections are parallel to each other, and specifically, on the plane of rotation, the center lines connecting the multiple water outlets of different water outlet sections always remain parallel. This embodiment uses two as an example for illustration, but it should be understood that two or more water outlets can be configured using the same conditions. Figure 11 A schematic diagram of the water outlet device according to the third embodiment of the present invention is shown. Figure 12 An exploded view of the water outlet device according to a third specific embodiment of the present invention is shown, in conjunction with... Figure 11 and 12 As can be seen, the structure of the water outlet device in this embodiment is basically the same as the overall structure of the previous embodiment, and will not be described again here. The main difference lies in the structure of the water outlet part 3'. Figures 13a-13b A schematic diagram of the water outlet of the third specific embodiment of the present invention is shown, as follows: Figure 13aand 13b As shown, the water outlet 3' is provided with two water outlet holes. The axes of the two water outlet holes are on the same plane and at a certain angle. Furthermore, the two water outlet holes gradually move away from each other from the upper end face to the lower end face of the water outlet 3', so that when the water outlet 3' rotates, the two water outlet holes can form two spiral water splashes. Figure 14 A schematic diagram illustrating the working principle of the water outlet device according to a third specific embodiment of the present invention is shown, as follows: Figure 14 As shown, the working principle of this water outlet device is the same as that of the aforementioned embodiment: water flows into the water outlet device through the inlet of the upper cover 1, and impacts the rotor 6 through the inclined water hole of the inclined water body 7, causing the rotor 6 to rotate. The speed reduction disk 5 achieves differential speed reduction rotation by engaging the outer teeth of the outer circumference with the corresponding inner teeth on the cover 2 and under the action of the eccentric wheel 61. The speed reduction disk 5 then drives the turntable 4 to rotate. The drive gear 41 on the turntable 4 meshes with the outer gears on multiple water outlet parts 3, thereby driving multiple water outlet parts to rotate synchronously. The water flows through the water outlet holes of the water outlet parts to form a spiral dynamic water outlet effect.

[0051] Figures 15a-15b The diagram shows cross-sectional views of the water outlet device in two states according to a third specific embodiment of the present invention. It can be seen that no matter what angle the water outlet is rotated to, the mounting surfaces on each water outlet (represented in the cross-sectional view as the line connecting the centers of the two water outlet holes) always remain parallel in this cross-section. This setting enables the water outlet device to have a better dynamic water outlet effect, more neat and beautiful water spray, and also to obtain a better massage effect.

[0052] According to other aspects of the present invention, the water outlet device can also be installed on the shower head structure. The specific connection and fitting method can be to install it on the shower head by means of threaded connection, snap-fit ​​connection or the like. The water inlet of the water outlet device can be connected to the water outlet pipe on the shower head in a corresponding sealed fit, so that the shower head has the above-mentioned dynamic water outlet effect of the present invention.

[0053] The specific embodiments of the present invention have been described above, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
