Abstract

This utility model provides a water outlet device, including a water outlet body with a first water outlet hole. The first water outlet hole includes a water splash forming hole and a jet hole. The top of the water splash forming hole allows horizontal or oblique water flow to enter along a direction deviating from the vertical central axis of the water splash forming hole, and the bottom communicates with the jet hole. The water passage area at the top of the water splash forming hole is larger than the water passage area at the bottom outlet end of the jet hole. All inner walls of the water splash forming hole are smooth surfaces. In this utility model, the water splash forming hole allows multiple water streams to fully collide. The water flow within the water splash forming hole is not obstructed by planes, corners, etc., thus preventing changes in flow direction and disturbances.

This utility model also provides a shower head, which has the same advantages.

Description

Technical Field

[0001] This utility model relates to the field of bathroom products technology, and particularly to the field of water outlet devices and shower heads. Background Technology

[0002] Shower heads, faucets and other bathroom products often use atomized water or spray water. These water output modes usually break up the water body by converging water streams at different angles to form atomized water droplets.

[0003] In existing bathroom products, the water outlet of granular water usually still adopts the conventional straight hole or conical hole structure. The water flow after the convergence and impact is discharged directly from the water outlet. The space for the water flow to impact each other is small, and it is easy to mix in the water outlet. The water breaking effect is poor and unstable, which affects the use effect. Utility Model Content

[0037] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0038] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0040] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0041] Reference Figures 1 to 11 In a preferred embodiment of the water outlet device of this utility model, a water outlet body 10 is provided, and a first water outlet hole 21 is provided on the water outlet body 10. The first water outlet hole 21 includes a water splash forming hole 211 and a jet hole 212. The top of the water splash forming hole 211 allows horizontal or oblique water flow to enter in a direction deviating from the vertical central axis of the water splash forming hole 211, and the bottom is connected to the jet hole 212. The water passage area at the top of the water splash forming hole 211 is larger than the water passage area at the bottom outlet end of the jet hole 212. All the inner walls of the water splash forming hole 211 are smooth walls. The water outlet device of this utility model has a first water outlet 21 divided into a water splash forming hole 211 and a jet hole 212. The water passage area at the top of the water splash forming hole 211 is larger than the water passage area at the outlet end of the jet hole 212. After the horizontal or oblique water flow enters from the top of the water splash forming hole 211 in a direction deviating from the vertical central axis of the water splash forming hole 211, it can rotate and oscillate fully along the wall surface of the water splash forming hole 211. Furthermore, the inner walls of the water splash forming hole 211 are all set as smooth walls. The water flow will not be obstructed by planes, corners, etc. within the water splash forming hole 211, thus changing its flow direction and causing disturbance. This allows a stable water flow vortex to be formed within the water splash forming hole 211, which can effectively prevent the water from re-aggregating after oscillation and breakage, and can effectively maintain the water flow velocity, thereby effectively improving the water oscillation and breakage effect. The jet hole 212 can further pressurize the water flow, effectively improving the particle effect and water pressure of the water after breakage at the first water outlet 21, and effectively improving the user experience.

[0042] As a preferred embodiment of the water outlet device in this utility model, it may also have the following additional technical features:

[0043] In this embodiment, the upper section of the water splash forming hole 211 is a cylindrical main hole section 2111, and the lower section is a spherical transition section 2112. The transition section 2112 gradually narrows from top to bottom, and the sidewalls of the main hole section 2111 and the transition section 2112 are smoothly connected. This water splash forming hole 211 has a regular structure, is easy to process and manufacture, and can also provide a stable and good guiding effect for the water flow inside the water splash forming hole 211. In other embodiments, the inner wall of the water splash forming hole 211 can also be entirely made of a spherical surface, or it can also be made of an ellipsoidal surface or other suitable smooth wall surface structures, or it can be made of a combination of smooth surfaces such as conical surfaces, spherical surfaces, and arc surfaces. Those skilled in the art can choose flexibly and are not limited to these.

[0044] Reference Figure 9 In this embodiment, the diameter R2 of the main orifice 2111 is 4 to 6 times the diameter R1 of the outlet end of the jet orifice 212. Under domestic water usage conditions, this provides ample space for water fragmentation and excellent pressurization. In this embodiment, the height h of the water droplet forming orifice 211 is 3 to 5 times the diameter R1 of the outlet end of the jet orifice 212. Similarly, under the water pressure and flow conditions of a domestic water usage environment, this ensures sufficient water fragmentation time, improves the water fragmentation effect, and effectively reduces the remixing of water droplets after fragmentation. In other embodiments, the dimensions of the first outlet orifice 21 can be flexibly adjusted according to the usage environment and needs.

[0045] Reference Figures 8 to 11 In this embodiment, the water outlet body 10 is provided with a first water distribution chamber 311 and a second water distribution chamber 321. The top of the first water outlet 21 is connected to the first water distribution chamber 311 through a horizontal first water passage 41. The first water passage 41 is connected to the second water distribution chamber 321 through a vertical second water passage 42. At least part of the water flow from the first water passage 41 deviates from the vertical central axis of the water splash forming hole 211. Thus, the horizontal water flow provided by the first water passage 41 can rotate and oscillate fully along the wall of the water splash forming hole 211 after entering the first water outlet 21, thereby causing the water to break up and form a shape. The water is formed into droplets, thus generating particulate water or spray water. The vertical water flow provided by the second water passage 42 can slow down the horizontal water flow provided by the first water passage 41 before it enters the first water outlet 21, thereby suppressing the rotation and oscillation of the horizontal water flow after entering the first water outlet 21 and reducing the degree of water breakup into droplets. Furthermore, by gradually increasing the vertical water flow input of the second water distribution chamber 321 while gradually decreasing the horizontal water flow input of the first water distribution chamber 311, the first water outlet 21 can be switched from particulate water outlet mode to direct water outlet mode. The structure is simple and convenient for processing, manufacturing and control.

[0046] Reference Figure 2 , Figure 4 and Figure 5 In this embodiment, the first water passage 41 includes a water flow acceleration section 411 and a water flow receiving section 412. The first water outlet 21, the water flow receiving section 412, and the water flow acceleration section 411 are connected in sequence. The second water passage 42 is aligned with the water flow receiving section 412. The water flow area S1 at the inlet end of the water flow acceleration section 411 is smaller than the water flow area S2 at the outlet end of the water flow receiving section 412. Because the water flow area S1 at the inlet end of the water flow acceleration section 411 is smaller than the water flow area S2 at the outlet end of the water flow receiving section 412, the water flow can pass smoothly through the first water passage 41, which can reduce the flow velocity loss. Specifically, the transverse water flow in the first water distribution chamber 311 enters... When water flows through the first outlet 21, it first needs to pass through a narrower water flow acceleration section 411 to increase the water flow velocity. Then, in the water flow receiving section 412, the vertical water flow input from the second water distribution chamber 321 via the second water passage 42 can collide with the horizontal water flow in the water flow receiving section 412, thus slowing down the horizontal water flow velocity. However, because the horizontal water flow is accelerated, the degree of inhibition of the horizontal water flow by the vertical water flow is weakened. That is, the proportion of vertical water flow required to neutralize the horizontal water flow is increased. Correspondingly, in the complete process of the horizontal water flow decreasing and the vertical water flow increasing, the time proportion of particulate water flow discharged from the first outlet 21 increases. In other embodiments, the first water passage 41 can also adopt any other suitable shape, such as a uniform straight line or curved channel, and is not limited to this.

[0047] In this embodiment, the water inlet area S1 of the water flow acceleration section 411 is greater than 1.2 times the water outlet area S3 of the jet hole 212 and less than 3 times the water outlet area S3 of the jet hole 212. Under the household water environment, it can produce optimal particulate water, and the particulate water mode of the first water outlet 21 can be maintained for a long time during the process of adjusting the flow rate of the first water distribution chamber 311 and the second water distribution chamber 321.

[0048] Reference Figure 2 Figure 4 , Figure 5 , Figure 6 , Figures 8 to 11 In this embodiment, the water outlet body 10 is also provided with a third water passage 43 that connects the first water distribution chamber 311 and the second water distribution chamber 321. The third water passage 43 is laterally offset from the first water outlet 21. The third water passage 43 can play an automatic adjustment role. When the water pressure or flow rate in the second water distribution chamber 321 is too high, the excess water can enter the first water distribution chamber 311 through the third water passage 43, and then enter the first water outlet 21 through the first water passage 41. This can make full use of the water pressure and flow rate of the external water source and improve the water output effect.

[0049] In this embodiment, a first water guide seat 51 is provided in the first water distribution cavity 311 corresponding to the first water outlet 21, and a first water passage 41 is provided in the first water guide seat 51. The bottom surface of the first water passage 41 is higher than the bottom surface of the first water distribution cavity 311 by a distance. In this way, when multiple first water outlets 21 are provided on the water outlet body 10, the water outlet uniformity of each first water outlet 21 can be improved.

[0050] Reference Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 10 and Figure 11 In this embodiment, the water outlet body 10 is also provided with a second water outlet hole 22. The second water outlet hole 22 is connected to the first water distribution chamber 311 and is used to output direct water. Direct water output is a water output mode with unidirectional water flow and a large water volume. It consumes less water pressure from the inlet, which allows more water outlet holes to be arranged on the water outlet body 10, effectively increasing the total water output. When the water output decreases due to the output of particulate water from the first water outlet hole 21, the second water outlet hole 22 can still maintain the output of direct water, ensuring sufficient water supply and meeting the user's needs.

[0051] In this embodiment, a first water outlet 21 is provided in both the central and outer edge regions of the water outlet body 10, and a second water outlet 22 is provided between the central and outer edge regions of the water outlet body 10. Thus, when the first water outlet 21 switches to the granular water mode, granular water can be generated simultaneously in the outer ring and center of the water outlet body 10, while the second water outlet 22 sprays water directly between the two layers of granular water, ensuring sufficient water output and visually presenting a more powerful water flow effect. Furthermore, the outer edge and central regions of the water outlet body 10 are generally areas with greater water flow disturbance and stronger water pressure; placing the second water outlet 22 in these locations helps to improve the water breaking effect. In other embodiments, the location and distribution of the first water outlet 21 and the second water outlet 22 can be flexibly adjusted as needed, for example, by using an alternating arrangement, and are not limited to this.

[0052] In this embodiment, a second water guide seat 52 is provided in the first water distribution cavity 311 corresponding to the second water outlet 22. A fourth water passage 44 is provided in the second water guide seat 52. The fourth water passage 44 connects the second water outlet 22 and the first water distribution cavity 311. The bottom surface of the fourth water passage 44 is higher than the bottom surface of the first water distribution cavity 311 by a distance. In this way, when multiple second water outlets 22 are provided, the uniformity of water output from each second water outlet 22 can be improved.

[0053] In this embodiment, the second water outlet 22 is a tapered hole that gradually narrows from top to bottom, which can increase the water flow velocity and achieve a pressurization effect. In other embodiments, the second water outlet 22 can also adopt other suitable shapes such as a straight circular hole. In this embodiment, the diameter of the second water outlet 22 is relatively small, making it difficult to provide space for water flow rotation and oscillation. This allows the second water outlet 22 to maintain a straight-out shower water mode. Furthermore, the water outlet direction of the fourth water passage 44 is directly opposite the vertical central axis of the second water outlet 22. Therefore, after the water flows into the second water outlet 22, it will more directly impact the inner wall of the second water outlet 22 and is less likely to rotate and oscillate along the inner side wall of the second water outlet 22. This also helps to maintain the second water outlet 22 in a straight-out shower water mode.

[0054] Reference Figures 1 to 3 , Figures 6 to 11 In this embodiment, the water outlet body 10 is provided with an inlet 33 for connecting to an external water source. The first water distribution chamber 311 is connected to the inlet 33 through a first water distribution channel 312, and the second water distribution chamber 321 is connected to the inlet 33 through a second water distribution channel 322. The water outlet body 10 is provided with a regulating valve 34 for adjusting the flow rate of the first water distribution channel 312 and the second water distribution channel 322. The regulating valve 34 can flexibly adjust the flow rate of the first water distribution chamber 311 and the second water distribution chamber 321, and correspondingly adjust the water outlet mode of the first water outlet 21.

[0055] Furthermore, in this embodiment, the second water outlet 22 is combined with the third water passage 43, enabling the second water outlet 22 to continuously discharge water for ease of use. In some embodiments, the third water passage 43 can be aligned with the second water outlet 22. Excess water after the water volume in the second water passage 42 reaches its upper limit can be directly discharged from the second water outlet 22 through the third water passage 43. This reduces interference with the water intake of the first water outlet 21, ensuring the stability of the water discharge pattern of the first water outlet 21. It also helps reduce disturbances in the water flow within the first water distribution chamber 311, reducing water pressure and flow rate losses, and thus increasing the water output. In other embodiments, the location of the third water passage 43 can be any other location, and is not limited to this.

[0056] In this embodiment, the regulating valve 34 includes a valve cavity 341 disposed within the water outlet body 10 and a valve core 342 rotatably disposed within the valve cavity 341. The side wall of the valve cavity 341 is provided with a first water inlet 351, a second water inlet 352, and an inlet connection 353. A first water distribution channel 312 is connected to the valve cavity 341 through the first water inlet 351, a second water distribution channel 322 is connected to the valve cavity 341 through the second water inlet 352, and an inlet 33 is connected to the valve cavity 341 through a main water inlet channel 354 via the inlet connection 353. The valve core 342 has a valve plate 343, which is attached to the side wall of the valve cavity 341 and is used to completely or partially block the first water inlet 351, the second water inlet 352, or the inlet connection 353 as it rotates. The valve plate 343 can simultaneously partially block the first water inlet 351 and the second water inlet 352. The regulating valve 34 has a simple structure, is easy to manufacture, and allows for flexible adjustment of the water outlet mode by rotating the valve core 342, making it easy to operate. In this embodiment, the first water inlet 351, the second water inlet 352, and the inlet connection 353 are similar in shape and size. There is one valve plate 343, which is slightly larger than any of the first water inlet 351, the second water inlet 352, and the inlet connection 353. The first water inlet 351 and the second water inlet 352 are adjacent to each other, and the inlet connection 353 is located on the opposite side of the first water inlet 351 and the second water inlet 352. In this way, the valve plate 343 can only completely close the first water inlet 351. 51. In use, either the second water outlet 352 or the water inlet connection 353, when the valve plate 343 is aligned with the water inlet connection 353, closes the water inlet connection 353, thus closing the water outlet device. When the valve plate 343 is aligned with the second water outlet 352, it closes the second water distribution channel 322. At this time, water will only flow into the first water distribution chamber 311 via the first water distribution channel 312, and the first water outlet 21 and the second water outlet 22 will only output direct water. Subsequently... Rotating the valve core 342 causes the valve plate 343 to gradually open the second water inlet 352 and gradually block the first water inlet 351. This allows for the regulation of the flow rates in the first water channel 312 and the second water channel 322, and also adjusts the flow ratio between the first water chamber 311 and the second water chamber 321, thereby adjusting the water outlet mode of the first water outlet 21. Furthermore, combined with the third water channel 43 and the second water outlet 22 provided in this embodiment, when the valve plate 343 closes the first water inlet 351, the water flow will only enter the second water chamber 321, but it can still enter the first water outlet 21 through the second water channel 42 and the first water chamber 311 through the third water channel 43 before exiting through the second water outlet 22. This maintains the water flow from the first water outlet 21 and the second water outlet 22, preventing accidental shutdown of the water outlet device and avoiding impact on the water heater, especially preventing accidental shutdown and restart of the gas water heater. This helps maintain a constant water temperature and improves the user experience.In other embodiments, the regulating valve 34 may also employ other commonly used valve body structures, and is not limited to this. In this embodiment, the water outlet body 10 has a handle section 15, and the main water inlet channel 354 is disposed inside the handle section 15. In some embodiments that do not have a second water outlet 22 and a third water passage 43, the structure of the regulating valve 34 in this embodiment can also be used to adjust only the water outlet mode of the first water outlet 21.

[0057] Reference Figure 1 , Figure 2 , Figure 6 , Figures 8 to 11 In this embodiment, the water outlet body 10 includes a water outlet plate 11, a water distribution plate 12, and a rear cover 13 arranged sequentially from bottom to top. A first water outlet hole 21 is disposed on the water outlet plate 11, and a second water passage 42 is disposed on the water distribution plate 12. A first water distribution cavity 311 is formed by the water outlet plate 11 and the water distribution plate 12, and a second water distribution cavity 321 is formed by the water distribution plate 12 and the rear cover 13. The structure is simple and convenient for processing, molding, and assembly. In other embodiments, the water outlet body 10 may also adopt other suitable shapes and structures, and is not limited to this.

[0058] In this embodiment, the water outlet body 10 also includes a cover 14, and the water outlet plate 11 is a flexible plate clamped by the water distribution plate 12 and the cover 14. This improves the sealing effect and reduces leakage. Furthermore, in this embodiment, the first water guide seat 51 and the second water guide seat 52 are both disposed on the water outlet plate 11. The first water passage 41 and the fourth water passage 44 are respectively formed into grooves on the first water guide seat 51 and the second water guide seat 52. Combined with the flexible water outlet plate 11 and the clamping of the cover 14, the first water guide seat 51 and the second water guide seat 52 can be pressed tightly onto the water distribution plate 12, thereby sealing the first water passage 41 and the fourth water passage 44 to form a hole. This allows the first water passage 41 and the fourth water passage 44 to stably guide the water flow laterally, facilitating the processing and shaping of the water outlet plate 11, the first water passage 41, and the fourth water passage 44. The water outlet plate 11 can be made of commonly used flexible materials such as silicone or rubber.
