[0015] As can be seen from the above description of the various embodiments of the present utility model, compared with the prior art, the various embodiments of the present utility model have the following beneficial effects:
[0016] In the first technical solution and related embodiments, a shower head with a distributed aeration unit and a rear air intake is provided. The shower head body is provided with a water inlet channel and at least two aeration units. Each unit includes an independent water inlet end, an air intake channel (opening on the back side of the body), and a water outlet end. The water inlet end is connected in parallel to the water inlet channel, and the water outlet end outputs aerated water. By connecting the independent aeration units in parallel, single-point fault isolation is achieved (a faulty unit does not affect the whole), improving the reliability of the shower head. The rear air intake achieves a compact layout, reduces vertical space, and saves costs.
[0017] In the second technical solution and related embodiments, a water outlet cover is added, which is connected to the shower head body to form a water outlet cavity. After the water outlet ends of each aeration unit flow into the water outlet cavity, they flow out evenly through the water outlet holes, realizing the concentrated and stable output of bubble water, eliminating the pressure difference between each aeration unit, and improving the uniformity of bubbles.
[0018] In the third technical solution and related embodiments, the shower head body is decomposed into a base, a water-passing component (with a water passage), an air-guiding component (with an air-water mixing chamber), a water-outlet component (with an air-bubble water chamber), and a connecting component; the water-passing component is connected to the water inlet, the air-guiding component and the water-passing component form an air-guiding channel, and the connecting component fixes all components; the modular design improves assembly efficiency, and the air path and water path are strictly isolated to prevent leakage.
[0019] In the fourth technical solution and related embodiments, the water-passing component and the air-guiding component are connected by a boss and a groove, and the height of the boss is greater than the depth of the groove to form an air-guiding channel. This assembly structure ensures that the air path is unobstructed while effectively preventing misalignment of the components and stably maintaining the vacuum degree of the air-water mixing chamber.
[0020] In the fifth technical solution and related embodiments, a radial flange is provided on the outer periphery of the water outlet component to press against the base, thereby sealing the air inlet passage and the water outlet passage and blocking the backflow of water into the air inlet passage.
[0021] In the sixth technical solution and related embodiments, the water-passing component and the water inlet end are connected by a water seal to prevent water from leaking into the air intake and obstructing air intake.
[0022] In the seventh technical solution and related embodiments, the cross-section of the water passage gradually narrows, accelerating the water flow through the Venturi effect; the air intake component expands through the flow cross-section (the cross-sectional area of the air-water mixing chamber outlet is larger than that of the water passage outlet but much smaller than that of the water outlet chamber), resulting in a decrease in flow velocity and pressure. The air-water mixing chamber generates negative pressure under the Bernoulli effect, enabling the air intake passage to efficiently draw in air.
[0023] In the eighth technical solution and related embodiments, the water outlet is provided with a multi-layer composite filter screen (covering the bubble water cavity) and a fixing frame. The fixing frame and the cavity are press-fitted to the filter screen, so that the gas-liquid mixture in the gas-water mixing cavity is sheared by the filter screen to generate micro-nano bubbles.
[0024] In the ninth technical solution and related embodiments, the filter screen is arranged in two sets along the axial direction of the water passage cavity. The double shearing improves the efficiency of bubble breaking, improves the uniformity of the output bubble particle size distribution, and makes the bubble particle size finer.
[0025] In the tenth technical solution and related embodiments, the six foaming units are arranged in a ring array to make the water flow distribution more uniform and avoid bubble size fluctuations caused by uneven local water pressure; each foaming unit corresponds to two air inlets, which are symmetrically arranged on both sides of the water inlet end, and the air intake is increased through dual air intake.

[0042] See Figures 1 to 8 ,like Figure 1 As shown, a shower head includes a shower head body and a water outlet cover 3.
[0043] The showerhead body has a water inlet channel 11 and at least two aeration units 2. Each aeration unit 2 has a water inlet end 12, an air inlet channel 13, and a water outlet end 28. The water inlet end 12 of each aeration unit 2 is connected to the water inlet channel 11, the air inlet channel 13 opens onto the surface of the showerhead body opposite to the water outlet end 28, and the water outlet end 28 is used to output aerated water. A water outlet cover 3 is connected to the showerhead body, and the two together form a water outlet chamber 32. The water outlet ends 28 of each aeration unit 2 are connected to the water outlet chamber 32. After the water flow from the water outlet ends 28 of each aeration unit 2 converges into the water outlet chamber 32, it flows out evenly through the water outlet holes 31 on the water outlet cover 3, achieving a concentrated and stable pressure output of aerated water, eliminating pressure differences between the aeration units 2, and improving the uniformity of the bubbles.
[0044] The shower head body includes a base 1 and at least two aeration units 2.
[0045] Base 1, such as Figure 2 and 3As shown, it has a handle, and the water inlet of the handle is connected to the annular water inlet channel 11 set in the center of the top of the base 1. The water inlet end 12 and air inlet channel 13 of each foaming unit 2 are set in the base 1. Specifically, the base 1 is provided with several mounting slots (not marked in the figure) for fixing the foaming unit 2. Several water inlets 12 are provided in the middle of the mounting slots. These water inlets 12 are distributed in a ring array on the water inlet channel 11. In this embodiment, the number of water inlets 12 is six, but the specific number can be increased or decreased according to the actual situation and is not limited to six. The opening of each water inlet 12 faces the water outlet direction, and the water inlet 12 is directly connected to the water inlet channel 11 to realize the parallel water supply of the foaming units 2 and ensure that the water flow can be evenly distributed to each foaming unit 2. Two air inlets 13 are symmetrically opened on both sides between the water inlet end 12 and the mounting slot. The air inlets 13 open on the side surface of the base 1 opposite to the water outlet end 28. Integrating the air intake 13 into the back of the base 1 reduces the structural thickness of the shower head, shortens the air path length, and lowers airflow resistance. Simultaneously, the parallel layout of the ring array (six water inlet units 12) enables uniform water flow distribution, avoiding localized water pressure fluctuations. Furthermore, the dual-intake method increases the air intake volume of the air intake 13, controls air pressure fluctuations, and ensures the stability of the negative pressure.
[0046] Bubble-generating unit 2, such as Figure 6 and Figure 7 As shown, it includes a water-passing component 21, an air-exhausting component 22, a water-exhausting component 23, a connecting component 24, a filter screen 25, and a fixing frame 26.
[0047] There are several foaming units 2, which are connected in parallel to the water inlet channel 11 and are arranged correspondingly to the air inlet channel 13. Specifically, in this embodiment, there are six foaming units 2, which is the same as the number of water inlet end 12. They are also arranged in a ring array on the substrate 1. This layout can make the water flow distribution more uniform and avoid fluctuations in bubble size due to uneven local water pressure.
[0048] The water-passing component 21 is provided with a water-passing channel 211, which is connected to the water inlet end 12. Specifically, as follows: Figure 3 and Figure 7 As shown, the water-passing component 21 has a disc-shaped structure with a water passage 211 protruding in the direction of water outlet in its middle. The cross-section of the water passage 211 gradually narrows along the water flow direction, which can accelerate the water flow through the Venturi effect. According to Bernoulli's law, the greater the flow velocity, the lower the pressure, which provides the flow velocity conditions for the formation of the negative pressure chamber at the outlet of the water-passing component 21. A sealing ring 14 is provided between the water-passing component 21 and the water inlet end 12. Specifically, the top of the water-passing component 21 has an annular first sealing groove 213, and the water inlet end 12 has a corresponding second sealing groove (not shown in the figure). The O-ring 14 is nested in both sealing grooves to achieve a seal between the water-passing component 21 and the water inlet end 12, preventing water from the water inlet end 12 from leaking into the air intake duct 13 and hindering the intake of air.
[0049] The air intake component 22 is provided with an air-water mixing chamber 221 connected to the water passage 211. An air intake passage 27 is formed between the air intake component 22 and the water passage component 21, connecting the air intake passage 13 and the air-water mixing chamber 221. Specifically, the bottom of the air-water mixing chamber 221 is provided with a tapered channel opening into the water passage component 21. This tapered channel is used to adapt to the water passage 211 of the water passage component 21 and is suitable for surrounding the water passage 211, forming the air intake passage 27 between the two. The inlet cross-sectional area of the air-water mixing chamber 221 is larger than the outlet cross-sectional area of the water passage 211. After the water flows into the air-water mixing chamber 221, the flow cross-section expands (the inlet cross-sectional area of the air-water mixing chamber 221 is larger than the outlet cross-sectional area of the water passage 211 but much smaller than the water outlet chamber 32), resulting in a decrease in flow velocity and pressure. In the air-water mixing chamber 221, a negative pressure is generated according to the Bernoulli effect, thereby enabling the air intake passage 13 to efficiently draw in air. The water-passing component 21 and the air-guiding component 22 are engaged by several bosses 212 and grooves 222. The air-guiding component 22 has several grooves 222 arranged circumferentially on its surface facing the water-passing component 21. The bottom of the water-passing component 21 facing the air-guiding component 22 has bosses 212 corresponding to the grooves 222 around the water passage 211. The height of the bosses 212 is greater than the depth of the grooves 222, and an air passage 27 is formed between two adjacent bosses 212. This assembly structure ensures unobstructed airflow while effectively preventing component misalignment and maintaining a stable vacuum in the air-water mixing chamber 221. The outer wall of the water-passing component 21 has radially protruding annular protrusions 223 for overlapping the water-exit component 23.
[0050] The water outlet 23 is a hollow cylinder, which has an air-water chamber 232 that connects to the air-water mixing chamber 221, such as... Figure 6 and Figure 7 As shown, the water outlet 23 has a radial flange 231 on its outer periphery. This flange 231 abuts against the wall of the mounting groove of the base 1 to seal the passage between the air inlet 13 and the water outlet 32, preventing water in the water outlet 32 from flowing back into the air inlet 13. Figure 7 As shown, the inner wall of the bubble water chamber 232 is provided with an annular groove 234 that matches the annular protrusion 223 of the water passage component 21, for supporting the water passage component 21. Several intersecting ribs 233 are arranged at the outlet of the bubble water chamber 232 at the bottom of the water outlet component 23 for supporting the filter screen 25.
[0051] Connector 24, such as Figure 3 As shown, its function is to fix the water-passing component 21, the air-drawing component 22, and the water-discharging component 23 to the base 1. Specifically, the wall of the mounting groove of the base 1 is provided with external threads, and the connector 24 is provided with internal threads. The connector 24 is sleeved on the wall of the mounting groove and presses the flange 231 of the water-discharging component 23 against the groove wall.
[0052] Filter 25, such as Figure 1 , Figure 3 and Figure 7As shown, a multi-layer composite filter screen 25 is used. The diameter of the filter screen 25 matches that of the bubble water chamber 232, covering the inlet of the bubble water chamber 232. There is at least one set of filter screens 25; in this embodiment, there are two sets of filter screens 25, arranged side-by-side along the axial direction of the water passage chamber. The filter screen 25 uses six layers of 200-mesh stainless steel mesh or five layers of 250-mesh mesh mesh. Through a dual shearing action, the bubble breaking efficiency is improved, the uniformity of the output bubble particle size distribution is increased, and the bubble particle size is finer.
[0053] Fixture 26, such as Figure 1 , Figure 7 and Figure 8 As shown, there are two ring-shaped structures with several radially protruding spherical protrusions 261 on their periphery, which are interference-fitted with the inner wall of the bubble water chamber 232 to press the filter screen 25. Through the friction between the spherical protrusions 261 and the inner wall of the bubble water chamber 232, the filter screen 25 can be pressed tightly, while making it easier to install the fixing bracket 26 into and remove it from the water outlet 23.
[0054] The water outlet cover 3 and the base 1 are detachably connected. Specifically, the base 1 and the water outlet cover 3 can be connected by a snap-fit structure or by screws 15. Figure 1 , Figure 3 and Figure 5 As shown, this embodiment uses screws 15 for fastening. Several radially protruding first protrusions 16 are provided around the periphery of the base 1. The first protrusions 16 are provided with first screw holes. The water outlet cover 3 is provided with several radially protruding second protrusions 33. The second protrusions 33 are provided with second screw holes corresponding to the first screw holes. The base 1 and the water outlet cover 3 are fastened together by screws 15.
[0055] like Figure 3 As shown, the surface of the water outlet cover 3 is provided with several water outlet holes 31. After the water outlet cover 3 is connected to the substrate 1, a water outlet cavity 32 is formed above the water outlet holes 31 for storing micro-nano bubble water cut by each bubble-generating unit 2.
[0056] The specific working process of this shower head is as follows:
[0057] Water flows from the inlet channel 11 to each inlet end 12 and enters the corresponding bubble-forming unit 2. In the bubble-forming unit 2, the water first passes through the water passage 211 of the water passage 21. As the cross-section of the water passage 211 gradually narrows along the water flow direction, the water flow is significantly accelerated as it passes through, forming a high-speed water flow. Subsequently, the high-speed water flow enters the air-water mixing chamber 221 of the air intake component 22. Due to the expansion of the flow cross-section, the flow velocity decreases and the pressure drops, forming a negative pressure in the air-water mixing chamber 221. At this time, the air inlet 13, which opens at the top of the back side of the substrate 1, is connected to the air-water mixing chamber 221 through the air intake 27. Under the action of negative pressure, outside air is drawn into the air-water mixing chamber 221 and fully mixes with the high-speed water flow to form initial bubble water. The initial air-mixed bubble water flow rate remains at a high level, continuing to impact the high-mesh multi-layer composite filter 25 in the water outlet 23. The air in the water flow is further cut and refined by the fine mesh of the filter 25, generating micro-nano-scale bubbles with smaller particle size and more uniform distribution.
[0058] The water stream containing micro-nano bubbles generated by each foaming unit 2 flows into the water outlet chamber 32 through the water outlet 28. The water outlet chamber 32 balances the water pressure fluctuations of each unit, ensuring thorough mixing and stable flow of the bubble-water mixture. Finally, the water stream with uniformly distributed micro-nano bubbles is ejected at high speed from the water outlet 31, resulting in a highly efficient cleaning or oxygenating water output effect.
[0059] This embodiment provides a shower head with distributed aeration units 2 and a rear air intake structure. The shower head body has a water inlet channel 11 and at least two aeration units 2. Each unit includes an independent water inlet end 12, an air intake channel 13 (opening on the back side of the body), and a water outlet end 28. The water inlet end 12 is connected in parallel to the water inlet channel 11, and the water outlet end 28 is used to output aerated water. By adopting a parallel independent aeration unit 2 design, single-point fault isolation is achieved (i.e., a faulty unit does not affect the normal use of the entire shower head), improving the reliability of the shower head. The rear air intake method achieves a compact layout, reduces vertical space occupation, and saves costs.
[0060] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
