Description

Technical Field

[0001] The utility model relates to the field of sanitary wares, in particular to a microbubble water outlet device. Background Art

[0002] When the existing shower head allows water flow to enter the shower head through a pressurization means, the external air pressure forces the water flow to accelerate and discharge water. However, too high water pressure gives people a sense of urgency or tingling, affecting the user experience. Therefore, microbubble shower heads have emerged. Usually, the water flow in the water flow channel of the shower head is driven to rotate to form a vortex to generate microbubble water for spraying, making people feel comfortable and relaxed, and having a good cleaning effect.

[0003] However, in order to produce a better microbubble effect, a microbubble generating device is arranged in the face cover assembly. Since the length of the holes for generating microbubbles needs to be long enough, the thickness of the face cover assembly is relatively thick or the area of the face cover becomes larger, which is not beautiful enough. In addition, the existing microbubble generation is also equipped with a filter screen, etc., with a complex structure, resulting in an increase in the volume of the shower head, damaging the aesthetic degree of the state of the shower head, and the added filter screen is prone to blockage, leading to risks of abnormal microbubble function and water leakage.

[0037] Embodiment 1

[0038] Referring to Figures 1 - 8 , a microbubble water outlet device includes a water outlet body 10 and a microbubble generator 20. The water outlet body 10 has a water inlet part 11 and a water outlet part 12. The water inlet part 11 is used for water inlet, and the water outlet part 12 is connected to and communicates with the water inlet part 11 to discharge water. The microbubble generator 20 is installed in the water inlet part 11 or at the connection between the water inlet part 11 and the water outlet part 12. The microbubble generator 20 is provided with a plurality of reducing holes 21 communicating with the water inlet part 11. The inner diameter of the reducing holes 21 is set to gradually increase along the water flow direction so that microbubbles are generated when the water flows through, and the water outlet part 12 outputs water flowers containing microbubbles.

[0039] Among them, a plurality of reducing holes 21 are arranged in the microbubble generator 20 and are spaced apart in the radial direction. Each reducing hole 21 extends along the axial direction of the microbubble generator 20 and penetrates the microbubble generator 20. The inner diameter of the water inlet end of the reducing hole 21 is smaller than the inner diameter of the water outlet end of the reducing hole 21. After the water flow in the water inlet part 11 enters the reducing hole 21, the water pressure gradually decreases, and the tiny bubbles dissolved in the water flow precipitate to form a water flow with microbubbles. The number of the reducing holes 21 can be one, two, three, four or even more, which is not limited herein.

[0040] The water outlet part 12 and the water inlet part 11 are detachably connected, such as snap connection or threaded connection, etc. A sealing ring is also arranged at the connection between the water outlet part 12 and the water inlet part 11 for sealing. The microbubble generator 20 and the water inlet part 11 or the connection between the microbubble generator 20 and the connection between the water inlet part 11 and the water outlet part 12 can be fixed by means of concave-convex fit or threaded fit, etc. In this embodiment, a radially extending flange 22 is arranged on the outer periphery of the microbubble generator 20. The flange 22 is located at the water inlet end of the microbubble generator 20, and the flange 22 is clamped at the connection between the water inlet part 11 and the water outlet part 12. A groove can be formed between the water inlet part 11 and the water outlet part 12 for the flange 22 to be inserted.

[0041] A plurality of annular grooves 23 are provided on the outer periphery of the microbubble generator 20. The plurality of annular grooves 23 are spaced apart in the axial direction. A sealing ring is provided in the annular groove 23 for sealing cooperation with the inner wall of the water inlet part 11 or the inner wall of the water outlet part 12.

[0042] In this embodiment, the water outlet device can be a shower head, a faucet, etc. In the figure, a shower head is taken as an example. The water inlet part 11 is a handle, and the handle is provided with a water inlet channel 13. The water outlet part 12 is a face cover assembly. The face cover assembly is detachably connected to the handle and is provided with at least one water outlet channel 14. Different water outlet channels 14 have different water outlet effects. The microbubble generator 20 is installed at the connection between the handle and the face cover assembly, and the variable diameter hole 21 communicates the water inlet channel 13 and the water outlet channel 14. Then, no matter what kind of water outlet effect the face cover assembly has, it has the microbubble function.

[0043] Among them, the face cover assembly can be realized by a conventional structure with at least one water outlet function. In the figure, it includes a water outlet hole plate 15, a face cover 16, a water distribution plate assembly 17, a fixed plate 18, an upper cover 19, etc. The upper cover 19 is connected to the handle and has an installation groove 25. The fixed plate 18, the water distribution plate assembly 17, the water outlet hole plate 15, etc. are arranged in the installation groove 25. The fixed plate 18 is provided with a plurality of water inlet holes for communicating with the water inlet channel 13. The water distribution plate assembly 17 is communicated with the fixed plate 18. The water outlet hole plate 15 is connected to the water distribution plate assembly 17 and forms at least one water outlet channel 14. The water outlet hole plate 15 is provided with water outlet holes corresponding to different water outlet channels 14. The water flow is guided to the corresponding water outlet channels by the water distribution plate assembly 17 and then sprayed out through the corresponding water outlet holes. The face cover 16 covers the outside of the water outlet hole plate 15 and is rotatably connected to the upper cover 19.

[0044] The working principle of the device of the present utility model is as follows:

[0045] When water enters the water inlet part 11, the water flow enters the variable diameter hole 21 when passing through the microbubble generator 20. Since the inner diameter of the variable diameter hole 21 gradually increases, the water pressure of the water flow gradually decreases, so that the tiny bubbles dissolved in the water flow are precipitated, generating a water flow containing microbubbles and flowing into the water outlet part 12 for spraying, realizing the microbubble water outlet effect.

[0046] Embodiment Two

[0047] See Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 、 Figures 9 - 13, A microbubble water outlet device, whose main structure is the same as that of the first embodiment, except that: in order to achieve a better microbubble water outlet effect, a swirl member 30 is also provided. The swirl member 30 is installed at the water inlet end of the microbubble generator 20 so that the water flow generates a swirl and then enters the microbubble generator 20. The swirl member 30 is used to make the water flow into a swirl state, and the bubbles dissolved in the water are broken up and precipitated by the rotational cutting force of the water flow, and then enter the microbubble generator 20.

[0048] Among them, the swirl member 30 can be installed inside or outside the microbubble generator 20, which can be set according to actual needs. In the figure of this embodiment, a water chamber 24 communicating with the variable diameter hole 21 is provided at the water inlet end of the microbubble generator 20. An installation groove 25 is provided on the inner wall of the opposite end of the water chamber 24 in the axial direction with respect to the swirl member 30, and the swirl member 30 is embedded in the installation groove 25. Protrusions can be provided on the outer periphery of the swirl member 30 to be tightly fitted with the inner wall of the installation groove 25.

[0049] The swirl member 30 includes a connected connecting portion 31 and a guiding portion 32, which are of a split structure or an integrally formed structure. The guiding portion 32 is located at the water inlet end of the swirl member 30 to guide the water flow to the connecting portion 31; the connecting portion 31 is provided with a plurality of water passing holes 33, and the plurality of water passing holes 33 are circumferentially spaced along the guiding portion 32. The water passing holes 33 communicate with the variable diameter hole 21 and extend spirally or obliquely along the axis, and the flow holes are used to change the water flow direction to generate a swirl.

[0050] Specifically, the guiding portion 32 is arranged at the middle position of the connecting portion 31, and a guiding inclined surface 34 is provided on the outer periphery of the guiding portion 32. The guiding inclined surface 34 extends radially outward along the water flow direction, so that the outer diameter of the end of the guiding portion 32 connected to the connecting portion 31 is larger than the outer diameter of the other end of the guiding portion 32, that is, the guiding portion 32 is similar to a cone, so that the water flow enters the water passing holes 33 along the guiding inclined surface 34, playing a role of guiding and buffering.

[0051] Furthermore, through holes 35 can also be provided on the guiding portion 32. The through holes 35 axially penetrate the guiding portion 32, and the through holes 35 communicate with the water chamber 24 and the variable diameter hole 21. The through holes 35 on the guiding portion 32 can be set to have an inner diameter gradually increasing along the water flow direction, which is also beneficial to the precipitation of microbubbles.

[0052] For this structure in this embodiment, see Figures 11 - 13 , when the water flow flows into the water inlet channel 13, under the action of the swirl member 30, the water flow forms a swirl state in the water chamber 24 to precipitate microbubbles. This is the first stage of microbubble generation. The swirling water flow then enters the variable diameter hole 21 of the microbubble generator 20 and precipitates microbubbles again. This is the second stage of microbubble generation. By adopting this two-stage microbubble generation method, the generation amount of microbubbles is greatly increased.

[0053] In this embodiment, a swirl element 30 is added on the basis of the microbubble generator 20, which can avoid the problem of poor microbubble effect caused by the damage of water pressure due to complex water circuits and other situations.

[0054] The terms "first", "second", etc. that appear in the present utility model are only for convenient description to distinguish different components with the same name, and do not indicate the sequence or primary-secondary relationship.

[0055] In the description of the present utility model, the orientation or positional relationship indicated by "up", "down", "left", "right", "front" and "back" is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model, rather than indicating or implying that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, so it should not be construed as a limitation on the protection scope of the present utility model.

[0056] In addition, in the description of the present application, unless otherwise specified, "a plurality of" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0057] The above is only the specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification made to the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
