Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a micro-bubble water forming structure and a shower head. Background Art

[0002] Sparkling water has a high cleansing and massage effect, so many shower heads and faucets have a sparkling water function. Currently, most sparkling water structures on the market use a method of forming a vortex and generating negative pressure, then sucking air and mixing it into the water. This type of structure is relatively complex. During installation, the air intake channel may be blocked due to dimensional errors of components, or after long-term use, scale may block the air intake channel, thereby affecting the sparkling water effect. Therefore, the utility model provides a structure that can generate sparkling water without sucking air. The structure is relatively simple and can solve the above-mentioned technical problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a bubble water forming structure with a simpler structure.

[0004] In a first aspect, a micro-bubble water forming structure is provided, comprising a water inlet chamber, a swirl chamber and a bubble water outlet nozzle.

[0005] One end of the swirl cavity is connected to the water inlet cavity through a tangential water inlet channel, and the other end is contracted to form a constriction and connected to the bubble water outlet.

[0006] There is at least one tangential water inlet channel, and the tangential water inlet channel is connected to the vortex chamber through a water inlet.

[0007] In order to improve the water flow speed and bubble water effect, the following structural parameters are also set:

[0008] The ratio of the area of the water inlet of the tangential water inlet channel to the area of the water outlet is 0.6-1.3.

[0009] The ratio of the diameter of the rotating circular cavity of the cyclone cavity to the diameter of the bubble water outlet nozzle is 2-3.7.

[0010] The ratio of the diameter of the rotating circular cavity of the swirl cavity to the length of the bubble water outlet nozzle is 0.85-2.8.

[0011] When water enters the vortex chamber, it flows through the tangential water inlet channel in a rotating manner and is concentrated at the constricted outlet, significantly increasing the flow rate. It is then ejected through the bubble water outlet. Because the micro-bubble water forming structure provided by this invention can significantly increase the water flow rate, a significant negative pressure is generated when the water is ejected from the bubble water outlet. This negative pressure causes a small amount of air in the water to separate. The separated air then mixes with the water, forming tiny bubbles in the water, thereby achieving the formation of micro-bubble water.

[0012] The microbubble water forming structure provided by the utility model separates air from water by negative pressure when forming microbubbles, i.e., there is no need to inhale air or reserve an air extraction channel, which makes the bubble forming structure simpler and eliminates the problem of bubble formation being affected by blockage of the air extraction channel.

[0013] Preferably, the ratio of the area of the water inlet of the tangential water inlet channel to the area of the water outlet is 0.8-1.1.

[0014] Preferably, the ratio of the diameter of the rotating circular cavity of the vortex cavity to the diameter of the bubble water outlet nozzle is 2.2-3.5.

[0015] Preferably, the ratio of the diameter of the rotating circular cavity of the vortex cavity to the length of the bubble water outlet nozzle is 1.05-2.6.

[0016] Preferably, there are three tangential water inlet channels, which are evenly distributed around the circumference of the vortex chamber.

[0017] In a second aspect, a shower head is provided, which adopts the micro-bubble water forming structure described in the first aspect.

[0018] Preferably, it includes a water outlet body and a water outlet panel, wherein the water outlet body is provided with a water inlet cavity, the water outlet panel is provided with a swirl cavity and a bubble water outlet nozzle, and the water outlet panel is provided with multiple groups of swirl cavities and bubble water outlet nozzles.

[0019] Preferably, to reduce the difficulty of molding the water outlet panel, a split assembly structure is adopted. The water outlet panel is provided with a mounting groove on the side facing the water inlet chamber. The bottom of the mounting groove is provided with a portion of the swirl chamber and is connected to the bubble water outlet. A water inlet block is installed in the mounting groove. The water inlet block is provided with a portion of the swirl chamber facing the bubble water outlet and the tangential water inlet channel is provided on the periphery.

[0020] Preferably, an axial water passage is provided between the mounting groove and the water inlet block, and the water passage is connected to the tangential water inlet channel, thereby extending the water inlet end of the tangential water inlet channel, avoiding the influence of the water flow in the water inlet cavity on the formation of the tangential water flow, and improving the consistency of the water flow direction in the tangential water inlet channel.

[0021] Preferably, to facilitate assembly, the tops of the water inlet blocks are connected together via a bracket and are pressed into the mounting groove by the cavity wall of the water inlet cavity.

[0022] From the above description of the present invention, it can be seen that the present invention has the following beneficial effects:

[0023] The microbubble water forming structure provided by the utility model separates air from the water by negative pressure when forming microbubbles. This means that there is no need for suction or reserved air extraction channels, making the bubble forming structure simpler and eliminating the problem of air extraction channel blockage affecting bubble formation.

[0024] By setting the parameter ratios of various structures, the water flow rate can be further increased, thereby forming a greater negative pressure to separate the air in the water. This allows the separated air sufficient time and space to mix with the water flow to form bubble water.

[0025] The water outlet panel adopts a split structure, which can reduce the difficulty of forming the water outlet panel;

[0026] The tops of the water inlet blocks are connected together by a bracket and are pressed into the installation groove by the cavity wall of the water inlet cavity, so as to facilitate assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] See also Figures 1 to 6 A micro-bubble water forming structure includes a water inlet chamber 1, a swirl chamber 2 and a bubble water outlet nozzle 3.

[0042] One end of the swirl chamber 2 is connected to the water inlet chamber 1 through a tangential water inlet channel 22, and the other end is contracted to form a constriction 21 and connected to the bubble water outlet 3.

[0043] There is at least one tangential water inlet channel 22 . In this embodiment, there are three tangential water inlet channels 22 , which are evenly distributed around the circumference of the vortex chamber 2 . The tangential water inlet channel 22 is connected to the vortex chamber 2 through a water inlet 23 .

[0044] In order to improve the water flow speed and bubble water effect, the following structural parameters are also set:

[0045] The ratio of the area of the water inlet 23 of the tangential water inlet channel 22 to the area of the water outlet is 0.6-1.3. Preferably, the ratio is 0.8-1.1. For example, in this embodiment, the ratio of the area of the water inlet 23 of the tangential water inlet channel 22 to the area of the water outlet is 1.

[0046] The ratio of the diameter of the rotating circular cavity of the vortex cavity 2 to the diameter of the bubble water outlet nozzle 3 is 2-3.7. Preferably, the ratio adopted is 2.2-3.5. For example, in this embodiment, the ratio of the diameter of the rotating circular cavity of the vortex cavity 2 to the diameter of the bubble water outlet nozzle 3 is 2.8.

[0047] The ratio of the rotating circular cavity diameter of the vortex cavity 2 to the length of the bubble water outlet nozzle 3 is 0.85-2.8. Preferably, the ratio adopted is 1.05-2.6. For example, in this embodiment, the ratio of the rotating circular cavity diameter of the vortex cavity 2 to the length of the bubble water outlet nozzle 3 is 2.

[0048] When water enters the vortex chamber 2 in a rotating manner through the tangential water inlet channel 22, and is concentrated at the constricted opening 21, significantly increasing the flow rate. It is then ejected through the bubble water outlet 3. Because the micro-bubble water forming structure provided by this invention can significantly increase the water flow rate, when the water is ejected from the bubble water outlet 3, a considerable negative pressure is generated. This negative pressure causes a small amount of air in the water to separate. The separated air then mixes with the water, forming tiny bubbles in the water, thereby achieving the formation of micro-bubble water.

[0049] In another embodiment, a shower head 4 adopts the micro-bubble water forming structure provided in the above embodiment.

[0050] The shower head 4 includes a water outlet body 41 and a water outlet panel 42 , wherein the water outlet body 41 is provided with a water inlet cavity 1 , the water outlet panel 42 is provided with a swirl cavity 2 and a bubble water outlet nozzle 3 , and the water outlet panel 42 is provided with multiple groups of swirl cavities 2 and bubble water outlet nozzles 3 .

[0051] In one embodiment, to reduce the difficulty of molding the outlet panel 42, a split assembly structure is employed. A mounting groove 421 is provided on the surface of the outlet panel 42 facing the water inlet chamber 1. The bottom of the mounting groove 421 defines a portion of the swirl chamber 2, which communicates with the bubble water outlet 3. A water inlet block 43 is mounted within the mounting groove 421. The water inlet block 43 defines a portion of the swirl chamber 2 facing the bubble water outlet 3, and the tangential water inlet channel 22 is provided around its periphery.

[0052] In addition, to facilitate assembly, the tops of the water inlet blocks 43 are connected together via a bracket 44 and are pressed into the mounting groove 421 by the cavity wall of the water inlet cavity 1 .

[0053] In another embodiment, in order to improve the swirl effect, an axial water passage 431 is provided between the mounting groove 421 and the water inlet block 43, and the water passage 431 is connected to the tangential water inlet channel 22, thereby extending the water inlet end of the tangential water inlet channel 22, avoiding the influence of the water flow in the water inlet chamber 1 on the formation of the tangential water flow, and improving the consistency of the water flow direction in the tangential water inlet channel 22.

[0054] The microbubble water forming structure provided by the utility model separates air from water by negative pressure when forming microbubbles, i.e., there is no need to inhale air or reserve an air extraction channel, which makes the bubble forming structure simpler and eliminates the problem of bubble formation being affected by blockage of the air extraction channel.
