A water outlet component

Abstract

This utility model discloses a water outlet assembly, including a body, an outlet component, and a rotating component. The body has a water inlet hole; the outlet component is adapted to rotate relative to the body around a first axis and has an outlet hole, which is either non-circular or its central axis does not coincide with the first axis, so that the water pattern changes when the outlet component rotates, achieving a massage or aesthetic effect. The outlet component and the body enclose an outlet cavity that connects the outlet hole and the water inlet hole. During water dispensing, water flows through the inlet hole, the outlet cavity, and the outlet hole in sequence. The output end of the rotating component is located in the outlet cavity and is adapted to rotate under hydraulic or motor drive. The rotating component and the outlet component are driven by a speed reduction transmission so that the rotation speed of the outlet component is less than that of the rotating component, thereby preventing the outlet component from rotating too fast and causing the water pattern change to be insignificant. Since the rotation speed of the rotating component is faster than that of the outlet component, it will cause vortices in the water in the outlet cavity, affecting the water pattern. A rectifier structure located in the outlet cavity is used to rectify the vortices and reduce the impact on the water pattern at the outlet hole.

Description

Technical Field

[0001] This utility model relates to the field of water discharge products, specifically to a water discharge component. Background Technology

[0002] In existing technologies, the water outlet component is typically rotated to change the water pattern at the outlet holes, achieving a massage or aesthetic effect. To prevent the water from directly acting on the water outlet component, causing excessively rapid changes in the water pattern or damage to the component, existing technologies often use a rotating component within the water outlet cavity. This rotating component is directly driven by the water, and a speed reduction transmission exists between the rotating component and the water outlet component to ensure the water outlet component's rotational speed is lower than that of the rotating component. However, because the rotating component's rotational speed is faster than that of the water outlet component, it creates vortices in the water within the outlet cavity, ultimately affecting the water pattern at the outlet holes.

[0022] The main body is equipped with a water inlet;

[0023] The water outlet component is adapted to rotate relative to the main body around a first axis. It is provided with a water outlet hole, which is either non-circular or its central axis does not coincide with the first axis. This causes the water pattern at the water outlet hole to change when the water outlet component rotates, thereby achieving a massage or aesthetic effect. The water outlet component and the main body enclose a water outlet cavity that connects the water outlet hole and the water inlet hole. When water is discharged, water flows through the water inlet hole, the water outlet cavity, and the water outlet hole in sequence.

[0024] The output end of the rotating component is located in the water outlet cavity, which is suitable for rotation driven by water force or motor. The rotating component and the water outlet component are driven by a speed reduction transmission so that the speed of the water outlet component is less than that of the rotating component, thereby preventing the water pattern from changing indistinctly due to the excessive speed of the water outlet component. Since the speed of the rotating component is faster than that of the water outlet component, it will cause vortices in the water in the water outlet cavity, which will affect the water pattern. The rectifier structure located in the water outlet cavity is used to rectify the vortices and reduce the impact on the water pattern at the water outlet.

In Scheme 2 and its preferred embodiments, the rectification structure consists of several rectification protrusions arranged around the water inlet end of the water outlet, with each rectification protrusion spaced apart to form a water passage gap between adjacent rectification protrusions.

The second tooth portion is located in the limiting cavity and is adapted to be positioned in the limiting cavity in a direction parallel to the rotation axis of the reducer. The positioning of the reducer is achieved through the design of the eccentric circular groove (first circular groove and limiting cavity), without the need to set a positioning shaft on the main body to rotate with the reducer, which is simpler and more convenient.

[0032] 9. In Scheme 9 and its preferred embodiments, the rotating component is provided with blades located in the water outlet cavity, and the main body is provided with a jet hole that connects the water inlet hole and the water outlet cavity.

[0033] 10. In Scheme 10 and its preferred embodiments, the speed reducer is provided with several water passage holes to assist water passage, reduce the impact of water on the speed reducer, and increase service life.

[0034] 11. In Scheme 11 and its preferred embodiments, the water outlet component is further provided with several ribs extending along the water flow direction of the water outlet hole. The ribs are spaced apart to accelerate the water flow and achieve further rectification, so as to improve the water pattern.

[0035] 12. In Scheme Twelve and its preferred embodiments, the main body includes an inner frame and a plate. The inner frame is provided with a first circular groove and a first arc groove. The first arc groove communicates with the side wall of the first circular groove. The plate is placed on the inner frame to close the openings of the first circular groove and the first arc groove, and forms a limiting cavity with the first arc groove. The two ends of the second tooth abut against the bottom of the first arc groove and the plate respectively for limiting engagement. The main body is formed in parts, thereby facilitating the installation and limiting of the second tooth. Attached Figure Description

[0055] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".

[0056] refer to Figures 1-12 A water outlet assembly includes a body 1, a water outlet component 2, a rotating component 3, and a speed reduction component 4. The water outlet assembly can be a shower head, faucet, spray gun, or other components mounted on the aforementioned parts.

[0057] The main body 1 includes an upper shell 11, a lower shell 12, an inner frame 13, and plates. The connection methods can include snap-fit, threaded connection, screw fastening, welding, bonding, etc.

[0058] refer to Figure 10 The upper shell 11 is provided with a water inlet hole 111.

[0059] The lower shell 12 is through the middle and connected and fixed to the upper shell 11 to form an installation cavity suitable for accommodating the water outlet 2, the rotating part 3, the deceleration part 4, the inner frame 13 and the jet plate 14.

[0060] refer to Figures 2-4 The inner frame 13 is through the middle and has a first circular groove 131 and a first arc groove 132. The projections of the first circular groove 131 and the first arc groove 132 are roughly gourd-shaped. The first circular groove 131 opens towards the direction of the upper shell 11, and the first arc groove 132 opens towards the direction of the upper shell 11. The first arc groove 132 is also connected to the side wall of the first circular groove 131.

[0061] refer to Figure 5 The plate is a jet plate 14, which has a rotating shaft 141, a limiting strip 142, and a jet hole 143. The jet hole 143 is used to drive the rotating component 3 to rotate by water entering through the jet hole 143. The jet plate 14 is placed on the inner frame 13 to close the openings of the first circular groove 131 and the first arc groove 132 facing the upper shell 11, and forms a limiting cavity 15 with the first arc groove 132. The limiting cavity 15 is connected to the side wall of the first circular groove 131, and the limiting strip 142 extends into the first arc groove 132.

[0062] refer to Figure 6 , Figure 10 The water outlet 2 is adapted to rotate relative to the body 1 around the first axis. In this embodiment, the water outlet 2 is located at the bottom of the first circular groove 131 and rotates with the first circular groove 131, and the middle part of the water outlet 2 extends out from the middle hole of the inner frame 13.

[0063] The water outlet component 2 is provided with a water outlet hole 21, which has an acceleration section to accelerate the water flow. The water-passing area of ​​the acceleration section gradually decreases towards the water outlet end of the water outlet hole 21, or the acceleration section is a micro-pore to increase the speed of the water flow when it enters the atmosphere. Alternatively, the water outlet component 2 may also have several ribs extending along the water-passing direction of the water outlet hole 21 within the water outlet hole 21, with the ribs spaced apart to accelerate the water flow and improve the water pattern. The water outlet hole 21 is not a circular hole with its central axis coinciding with the first axis; for example, the water outlet hole 21 is a non-circular hole. In this case, the central axis of the water outlet hole can coincide with the first axis, and the water pattern changes accordingly when the water outlet component 2 rotates. Alternatively, the central axis of the water outlet hole 21 does not coincide with the first axis, such as the central axis of the water outlet hole 21 being parallel or inclined relative to the first axis, so that the water pattern changes accordingly when the water outlet component 2 rotates. In this embodiment, the water outlet hole 21 is suitable for discharging blade water.

[0064] The water outlet component 2 includes a fourth tooth 22, which, in this embodiment, is an internal tooth protruding towards the first axis. The water outlet component 2 is generally T-shaped, with the water outlet end of the water outlet hole 21 protruding from the body 1. (Reference) Figure 10In this embodiment, the water outlet component 2 is located at the bottom of the first circular groove 131 and forms a water outlet cavity 5 with the main body 1. Specifically, in this embodiment, the water outlet component 2, the inner frame 13, and the jet plate 14 form the water outlet cavity 5. The water outlet cavity 5 connects the water outlet hole 21 and the water inlet hole 111. The water outlet cavity 5 is connected to the water inlet hole 111 through the jet hole 143.

[0065] The water outlet chamber 5 is equipped with a flow rectifying structure to rectify the water flow into the inlet end of the water outlet hole 21. The flow rectifying structure consists of several flow rectifying protrusions 23 arranged around the inlet end of the water outlet hole 21. The flow rectifying protrusions 23 are spaced apart to form a water passage gap between adjacent flow rectifying protrusions 23. The outlet end of the water passage gap is connected to the inlet end of the water outlet hole 21. (Refer to...) Figure 6 In this embodiment, the rectifying structure is a rectifying protrusion 23 protruding from the outer wall of the water outlet 2. Alternatively, the rectifying structure is a plurality of rectifying holes, the outlet end of which is connected to the inlet end of the water outlet 21. Water first enters other parts of the water outlet cavity 5, drives the rotating component 3, and then enters the rectifying holes before flowing into the inlet end of the water outlet 21. Alternatively, the rectifying structure is a rectifying water channel, which consists of multiple water channels with different water flow directions. The outlet end of the rectifying water channel is connected to the inlet end of the water outlet 21. Water first enters other parts of the water outlet cavity 5, drives the rotating component 3, and then enters the rectifying holes before flowing into the inlet end of the water outlet 21. The rectifying structure can be formed by the body 1 alone, the water outlet 2 alone, or the body 1 and the water outlet 2 together.

[0066] refer to Figure 7 , Figure 10 The output end of the rotating component 3 is located in the water outlet cavity 5, and it is adapted to be driven to rotate by water or a motor. In this embodiment, the rotating component 3 is an impeller, which is located inside the water outlet cavity 5. The rotating component 3 is inserted into the rotating shaft 141 and partially sits on the inner frame 13. The rotating component 3 is driven by water to rotate around the first axis. Specifically, the rotating component 3 includes blades 31 located in the water outlet cavity 5, and the jet hole 143 is adapted to discharge water toward the blades 31 to make the rotating component 3 rotate. The output end of the rotating component 3 is a first tooth 32, which protrudes outward along the radial direction of the rotating component 3. When a motor is used, the output shaft of the motor extends into the water outlet cavity 5 and engages with the rotating component 3 to prevent rotation; optionally, the input end of the rotating component 3 is located outside the water outlet cavity 5, and the output end is located inside the water outlet cavity 5, with the output shaft of the motor engaging with the input end of the rotating component 3 to prevent rotation.

[0067] refer to Figure 8 , Figure 10 The speed reducer 4 is located inside the water outlet chamber 5, and it connects the output end of the water outlet component 2 and the rotating component 3 so that the rotational speed of the water outlet component 2 is less than the rotational speed of the rotating component 3. Specifically, the speed reducer 4 includes a second tooth 41 and a third tooth 42, which protrude inward along the radial direction of the speed reducer 4. (Reference) Figure 11 , Figure 12The second tooth 41 engages with the first tooth 32 for deceleration, and the third tooth 42 engages with the fourth tooth 22 for deceleration. The third tooth 42 is located on the water outlet 2, and the second tooth 41 is partially located in the limiting cavity 15, and is adapted to engage with the limiting cavity 15 in a direction parallel to the rotation axis of the reducer 4 for upper limit engagement. Specifically, the two ends of the second tooth 41 abut against the bottom of the first arc groove 132 and the limiting strip 142 respectively to achieve limiting engagement. The reducer 4 is provided with several water passage holes 43 to assist water passage and reduce the impact of water on the reducer 4. Here, deceleration engagement means that the number of teeth between the two conforms to the deceleration requirement, that is, the number of teeth of the driven wheel is more than the number of teeth of the driving wheel.

[0068] During assembly, refer to Figure 10 First, place the inner frame 13 inside the lower shell 12. Then, position the water outlet 2 on the first circular groove 131 of the lower shell 12. Position the decelerator 4 on the water outlet 2 and engage the third tooth 42 of the decelerator 4 with the fourth tooth 22 of the water outlet 2. Place the second tooth 41 of the decelerator 4 into the first arc groove 132. Install the rotating part 3, which is positioned on the inner frame 13. Engage the first tooth 32 of the rotating part 3 with the second tooth 41 of the decelerator 4. Cover the inner shell with the jet plate 14 to form a water outlet cavity 5 with the water outlet 2 and the inner shell. Form a limiting cavity 15 with the first arc groove 132 to position the decelerator 4. Finally, connect the upper shell 11 and the lower shell 12 to complete the assembly.

[0069] When using, refer to Figure 10 When water enters through the inlet hole 111, the water enters the outlet cavity 5 through the jet hole 143 and impacts the blade 31 of the rotating component 3, causing the rotating component 3 to rotate. When the rotating component 3 rotates, it drives the speed reducer 4 to rotate, and the speed reducer 4 drives the outlet component 2 to rotate, so that the water pattern at the outlet hole 21 changes. Since the rotation speed of the rotating component 3 is faster than that of the outlet component 2, it will cause vortices in the water in the outlet cavity 5, which will affect the water pattern. The rectifier structure located in the outlet cavity 5 is used to rectify the vortices and reduce the impact on the water pattern at the outlet hole 21.

[0070] Compared with the prior art, this embodiment has the following beneficial effects:

[0071] In one exemplary embodiment, a water outlet assembly includes a body 1, a water outlet component 2, and a rotating component 3.

[0072] The main body 1 is provided with a water inlet 111;

[0073] The water outlet component 2 is adapted to rotate relative to the body 1 around a first axis. It is provided with a water outlet hole 21. The water outlet hole 21 is not a circular hole or the central axis of the water outlet hole 21 does not coincide with the first axis, so that when the water outlet component 2 rotates, the water pattern of the water outlet hole 21 changes to achieve a massage or aesthetic effect. The water outlet component 2 and the body 1 enclose a water outlet cavity 5 that connects the water outlet hole 21 and the water inlet hole 111. When water is discharged, water passes through the water inlet hole 111, the water outlet cavity 5, and the water outlet hole 21 in sequence.

[0074] The output end of the rotating component 3 is located in the water outlet cavity 5, which is suitable for rotation driven by water or motor. The rotating component 3 and the water outlet component 2 are driven by a speed reduction transmission so that the speed of the water outlet component 2 is less than the speed of the rotating component 3, thereby preventing the water pattern from changing too much due to the excessive speed of the water outlet component 2. Since the speed of the rotating component 3 is faster than the speed of the water outlet component 2, it will cause vortices in the water outlet cavity 5, which will affect the water pattern. The rectifier structure located in the water outlet cavity 5 is used to rectify the vortices and reduce the impact on the water pattern at the water outlet hole 21.

[0075] In one exemplary embodiment, the rectification structure consists of a plurality of rectification protrusions 23 arranged around the water inlet end of the water outlet 21. The rectification protrusions 23 are spaced apart so that a water passage gap is formed between adjacent rectification protrusions 23. The water outlet end of the water passage gap is connected to the water inlet end of the water outlet 21 to achieve the rectification effect.

[0076] In one exemplary embodiment, the rectification structure consists of several rectification holes, with the outlet end of the rectification holes connected to the inlet end of the outlet hole 21 to achieve a rectification effect.

[0077] In one exemplary embodiment, the rectification structure is a rectification water channel, which consists of multiple water channels with different water flow directions. The water outlet of the rectification water channel is connected to the water inlet of the water outlet 21 to achieve the rectification effect.

[0078] In one exemplary embodiment, the speed reducer 4 is located inside the water outlet chamber 5. It connects the output end of the water outlet 2 and the rotating member 3 so that the rotation speed of the water outlet 2 is less than the rotation speed of the rotating member 3. The output end of the rotating member 3 is a first tooth 32. The speed reducer 4 includes a second tooth 41 and a third tooth 42. The rotating member 3 includes a fourth tooth 22. The first tooth 32 meshes with the second tooth 41 to achieve a first-level speed reduction. The third tooth 42 meshes with the fourth tooth 22 to achieve a second-level speed reduction, thereby realizing a multi-level speed reduction transmission.

[0079] In one exemplary embodiment, the third tooth 42 is located on the water outlet 2, and the second tooth 41 is engaged with the body 1 in a direction parallel to the rotation axis of the reducer 4 to limit the position of the reducer 4 and prevent the reducer 4 from moving.

[0080] In one exemplary embodiment, the body 1 is provided with a first circular groove 131 and a limiting cavity 15. The water outlet 2 is located at the bottom of the first circular groove 131 and rotates with the first circular groove 131. The limiting cavity 15 is connected to the side wall of the first circular groove 131. The second tooth 41 is partially located in the limiting cavity 15 and is adapted to be positioned with the limiting cavity 15 in a direction parallel to the rotation axis of the reducer 4. The positioning of the reducer 4 is achieved through the design of the eccentric circular groove (first circular groove 131 and limiting cavity 15), without the need for a positioning shaft on the body 1 to rotate with the reducer, which is simpler and more convenient.

[0081] In one exemplary embodiment, the water outlet 21 is provided with an acceleration section to accelerate the water flow, thereby increasing the impact force of the water and making it more suitable for cleaning dirt or massaging.

[0082] In one exemplary embodiment, the rotating member 3 is provided with blades 31 located in the water outlet cavity 5, and the body 1 is provided with a jet hole 143 that connects the water inlet hole 111 and the water outlet cavity 5. The jet hole 143 is adapted to discharge water toward the blades 31 so that the rotating member 3 rotates. The rotating member 3 is driven to rotate by water power, which saves more energy and reduces costs.

[0083] In one exemplary embodiment, the speed reducer 4 is provided with a plurality of water passage holes 43 to assist water passage, reduce the impact of water on the speed reducer 4, and increase service life.

[0084] In one exemplary embodiment, the water outlet 2 is further provided with a plurality of ribs extending along the water flow direction of the water outlet 21 within the water outlet hole 21. The ribs are spaced apart to accelerate the water flow and achieve further rectification, resulting in a better water pattern.

[0085] In one exemplary embodiment, the body 1 includes an inner frame 13 and a plate. The inner frame 13 is provided with a first circular groove 131 and a first arc groove 132. The first arc groove 132 communicates with the side wall of the first circular groove 131.
