Description

Technical Field

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

[0002] When the water flow enters the existing shower head through a pressurization means, the external air pressure forces the water flow to speed up and flow out. However, too high water pressure gives people a sense of urgency or stinging, affecting the user experience. Therefore, microbubble shower heads have emerged. Usually, the water flow is driven to swirl in the water flow channel of the shower head to form a vortex to generate microbubble water and spray it out, making people feel comfortable and relaxed, and having a good cleaning effect.

[0003] However, the existing microbubble generating devices are usually additional functional components, usually located at the water inlet channel, far from the spraying end of the shower head face cover. Microbubbles are easily lost during the flow process, affecting the microbubble water output effect. 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 shower head state, and the added filter screen is easily blocked, leading to the risk of abnormal microbubble function and water leakage.

[0043] See Figure 1 、 Figure 2 , a microbubble shower head, comprising a water inlet assembly 10, a water distribution assembly 20 and a face cover assembly 30. The water inlet assembly 10 is used for inputting water flow. The water distribution assembly 20 is communicated with the water inlet assembly 10 and is provided with at least one water passage 21 to divide the water flow, that is, the water flow can enter different water passages 21. The number of the water passages 21 can be one, two or even more. In the figure, two water passages 21 are taken as an example. The face cover assembly 30 is connected to the water inlet assembly 10 and is provided with at least one water outlet cavity 31 communicated with the water distribution assembly 20 to output the water flow corresponding to the water passage 21, that is, different water outlet cavities 31 are used to realize different water outlet functions, and the number of the water outlet cavities 31 can correspond to the number of the water passages 21.

[0044] In the present utility model, one or more microbubble generating parts 40 are arranged in one of the water passages 21. Each microbubble generating part 40 includes a plurality of variable-diameter holes 41. The inner diameter of the variable-diameter holes 41 is set to gradually increase along the water flow direction so as to generate microbubbles when the water flow passes through. The water outlet cavity 31 communicated with the water passage 21 having the microbubble generating part 40 correspondingly outputs water flowers containing microbubbles.

[0045] Wherein, the water passage 21 having the microbubble generating part 40 is further provided with a water inlet groove 22 and a water outlet groove 23. The water inlet groove 22 is communicated with the water inlet assembly 10. The water outlet groove 23 is located on the side of the water distribution assembly 20 close to the face cover assembly 30 and is communicated with the corresponding water outlet cavity 31. The microbubble generating part 40 is communicated between the water inlet groove 22 and the water outlet groove 23. In the water passage 21 having the microbubble generating part 40, the number of the water inlet grooves 22 corresponds to the number of the microbubble generating parts 40, and the number of the water outlet grooves 23 is one.

[0046] In addition, the other water passages 21 without the microbubble generating part 40 are provided with a water passage cavity 24 and a water inlet 25. The water inlet 25 is communicated with the water inlet assembly 10. The water passage cavity 24 is communicated with the water inlet 25 and the water outlet cavity 31. Wherein, the water passage cavity 24 is not communicated with the microbubble generating part 40 and the water outlet groove 23, and the water inlet 25 is not communicated with the water inlet groove 22, that is, different water passages 21 are not communicated with each other.

[0047] For the microbubble shower head of the present utility model, the structure of the microbubble generating part 40 can be set according to the actual situation and has various implementation forms. Specifically, see the following:

[0048] Embodiment 1

[0049] Refer to Figures 3 - 8 , the microbubble generating part 40 is arranged near the water outlet cavity 31, and the water flow direction of the variable-diameter hole 41 is set to be the same as the water outlet direction of the water outlet cavity 31. The inner diameter of the end of the variable-diameter hole 41 opposite to the water inlet tank 22 is smaller than the inner diameter of the end of the variable-diameter hole 41 opposite to the water outlet tank 23. Then, when the water flow flows along the variable-diameter hole 41, the water pressure gradually decreases, and the tiny bubbles dissolved in the water flow are precipitated and directly enter the water outlet cavity 31, avoiding the loss during a long water path process.

[0050] In this embodiment, the water distribution component 20 includes a first water distribution plate 26 and a second water distribution plate 27. The first water distribution plate 26 is connected and communicated with the water inlet component 10 and is provided with a water inlet tank 22. The second water distribution plate 27 is opposite to the first water distribution plate 26 and is provided with at least one microbubble generating part 40. In the figure, the second water distribution plate 27 is provided with two symmetric microbubble generating parts 40. The side of the second water distribution plate 27 opposite to the face cover component 30 is also provided with a water outlet tank 23 to communicate with at least one microbubble generating part 40.

[0051] The first water distribution plate 26 also has an inlet 25 of other water passing channels 21. A water passing cavity 24 is arranged in the corresponding second water distribution plate 27. The water passing cavity 24 can be communicated with the inlet 25 to realize other water outlet functions.

[0052] The water inlet component 10 includes an upper cover 11 and a handle 12. The upper cover 11 is provided with a mounting groove 14 to mount the face cover component 30 and the water distribution component 20. The face cover component 30 can be rotatably connected to the mounting groove 14. The water distribution component 20 is arranged between the face cover component 30 and the bottom surface of the mounting groove 14. The handle 12 is axially through and is detachably connected to the upper cover 11 to form a water inlet channel 13. A fixing plate 15 is also arranged in the mounting groove 14. The fixing plate 15 is provided with through holes 16 corresponding to the water inlet tank 22 and the inlet 25, and the through holes 16 are communicated with the water inlet channel 13.

[0053] The face cover component 30 includes a base plate 32, a water outlet hole plate 33 and a cover body 34. The base plate 32 is connected to the water outlet hole plate 33 to form a water outlet cavity 31. The number of the water outlet cavities 31 corresponds to the number of the water passing channels 21. The base plate 32 is provided with a water inlet hole group 35 to communicate between the corresponding water passing channels 21 and the water outlet cavities 31, so that the water flow in the water passing channels 21 enters the corresponding water outlet cavities 31. The water outlet hole plate 33 is provided with a water outlet hole group 36 communicated with the water outlet cavity 31 for spraying the water flow in the water outlet cavity 31. The number of the water outlet hole groups 36 corresponds to the number of the water outlet cavities 31, and each water outlet hole group 36 is provided with a plurality of water outlet holes. The cover body 34 covers the side of the water outlet hole plate 33 facing away from the base plate 32.

[0054] In this embodiment, when the microbubble function is turned on, water enters the water passage 21 with the microbubble generating part 40. The water flows through the water inlet tank 22 and into the variable-diameter hole 41. Since the inner diameter of the variable-diameter hole 41 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 corresponding water outlet cavity 31 through the water outlet tank 23, and spraying out through the corresponding water outlet hole group 36 on the water outlet orifice plate 33.

[0055] Embodiment Two

[0056] See Figure 9 and Figure 10 In another embodiment, in order to achieve a better microbubble water outlet effect, a swirl element 50 can also be arranged in the water inlet passage 13 so that the water in the water inlet passage 13 generates a swirl and then enters the water distribution component 20. The swirl element 50 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.

[0057] The swirl element 50 can be arranged near the handle 12 of the upper cover 11 or near the upper cover 11 of the handle 12, etc., which can be set according to actual needs. The swirl element 50 includes a connected connecting part 51 and a guiding part 52. The connecting part 51 and the guiding part can be an integrally formed structure or a split structure. The guiding part 52 is located at the water inlet end of the swirl element 50 to guide the water flow to the connecting part 51; the connecting part 51 is provided with a plurality of water passing holes 53 spaced circumferentially along the guiding part 52. The water passing holes 53 are spirally extended or inclined axially to change the water flow direction to generate a swirl.

[0058] Specifically, the guiding part 52 is arranged at the middle position of the connecting part 51, and a guiding inclined surface 54 is arranged on the outer periphery of the guiding part 52. The guiding inclined surface 54 extends radially outward along the water flow direction, that is, the guiding part 52 is similar to a cone, so that the water flow enters the water passing holes 53 along the guiding inclined surface 54.

[0059] Adopting this structure, see Figure 11 When the water flow flows into the water inlet passage 13, microbubbles are precipitated under the action of the swirl element 50. This is the first stage of microbubble generation. When the water flow passes through the water inlet passage 13 and enters the water passage 21 with the microbubble generating part 40, microbubbles are precipitated 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.

[0060] In this embodiment, by adding the swirl element 50 on the basis of the microbubble generating part 40, the problem of poor microbubble effect caused by the damage of water pressure due to the complexity of the water path can be avoided.

[0061] Embodiment Three

[0062] See Figures 12 to 15, which is another embodiment of the microbubble generating part 40. In this embodiment, the water flow direction of the variable-diameter hole 41 is set perpendicular to or at an angle to the water outlet direction of the water outlet cavity 31, that is, the water flow direction of the variable-diameter hole 41 is not parallel to the water outlet direction of the face cover assembly 30. The inner diameter of the end of the variable-diameter hole 41 opposite to the water inlet groove 22 is smaller than the inner diameter of the end of the microbubble generator part opposite to the water outlet groove 23.

[0063] See Figure 14 , the water distribution component 20 in this embodiment is different from the water distribution component 20 in the previous text. It includes a third water distribution plate 28, on which a water inlet groove 22, a water outlet groove 23 and a microbubble generating part 40 are provided. The water inlet groove 22 penetrates the third water distribution plate 28 axially. The microbubble generating part 40 and the water outlet groove 23 are located on the side of the third water distribution plate 28 facing the face cover assembly 30. The number of the water inlet groove 22, the water outlet groove 23 and the microbubble generating part 40 is the same. In the figure, there are two water inlet grooves 22, two water outlet grooves 23 and two microbubble generating parts 40. The third water distribution plate 28 is also provided with other water passing channels 21 for realizing the conventional water outlet function.

[0064] In this embodiment, a cyclone can be provided in the water inlet assembly 10 or not. In the figure, the case of providing a cyclone is taken as an example.

[0065] See Figure 13 and Figure 15 When the water flow flows into the water inlet channel 13, microbubbles are precipitated under the action of the swirling member 50. This is the first stage of microbubble generation. The water flow passes through the water inlet channel 13 into the third water distribution plate 28, and enters the bubble generating part through the water inlet groove 22 to precipitate 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.

[0066] In this embodiment, a single third water distribution plate 28 is adopted, and the variable-diameter hole 41 of the microbubble generating part 40 is arranged horizontally, which is beneficial to reducing the thickness of the water distribution component 20 and reducing the weight.

[0067] The above is only the specific implementation manner of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modification made to the present invention using this concept shall fall within the scope of infringement of the protection scope of the present invention.
