[0002] Most current beauty showerheads use water to displace the beauty serum, and then adjust the concentration of the serum-water mixture by regulating the water flow into the serum reservoir. This method limits the use of the beauty serum to short periods; otherwise, prolonged exposure to the reservoir can lead to bacterial growth. Furthermore, as more water enters the reservoir, the serum is prematurely diluted, resulting in a poorer experience and making it difficult to accurately control the concentration of the serum-water mixture.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0030] refer to Figures 1-7 A water outlet mechanism for adjusting the concentration of functional liquid is described. In this embodiment, a shower head is used as an example. In fact, this structure can also be applied to other water outlet mechanisms, such as spray guns and kitchen shower heads. The shower head includes: a water pump 1 driven by water power, a functional liquid storage chamber 2, a water outlet channel 3, a water inlet channel 4, and a flow rate adjustment mechanism 5.

[0031] The inlet 11 of the hydraulic pump 1 is connected to the functional liquid storage chamber 2, and the outlet 12 is connected to the water outlet channel 3. The flow rate regulating structure is used to adjust the flow rate of the water used to drive the hydraulic pump 1 in the water inlet channel 4, thereby changing the pumping frequency of the hydraulic pump 1. The outlet 12 can also be connected to the water inlet channel 4, which is a simple substitution in this embodiment and will not be described in detail.

[0032] The aforementioned shower head adds beauty and skincare attributes to the traditional shower head, allowing people to care for their skin while showering. It also adds a beauty liquid adjustment mechanism, which controls the mixing ratio of beauty liquid and water by adjusting the suction frequency of the water pump 1. This solves the problems of inaccurate concentration of beauty liquid and water and the reduced effectiveness of beauty liquid after it is pre-diluted in the cavity.

[0033] Structurally, the hydraulic pump 1 includes a hydraulic drive section and a liquid suction and discharge section. The hydraulic drive section includes an impeller 14 that provides power to the pump and rotates under the impact of water flow, and a discharge port 13 that discharges the water flow impacting the impeller 14 into the water outlet channel 3. The liquid suction and discharge section includes an inlet 11 and a suction port 12. The liquid suction and discharge section is a diaphragm pump or a piston pump structure, which is the prior art.

[0034] To adjust the pumping frequency of the hydraulic pump 1, the flow rate regulating mechanism 5 includes a first water passage 51 and a second water passage 52; and an adjusting element for adjusting the water passage area of ​​the second water passage 52. The first water passage 51 serves as the main inlet for driving the impeller 14 of the hydraulic pump 1, while the second water passage 52 serves as an auxiliary inlet. By changing the water passage area of ​​the second water passage 52, more or less water can pass through it, thus reducing or increasing the amount of water flowing through the first water passage 51. Consequently, the amount of water used to drive the impeller 14 of the hydraulic pump 1 also decreases or increases, thereby lowering or increasing the pumping frequency of the hydraulic pump 1.

[0035] Specifically, the adjusting member adjusts the water passage area of ​​the second water passage hole 52 in the following way: the adjusting member translates along the axial direction of the second water passage hole 52 to separate from or embed into the second water passage hole 52.

[0036] The flow rate regulating mechanism 5 includes an inclined water body 53; a second water passage hole 52 is provided at the axis of the inclined water body 53, and inclined water passage holes 51 are distributed in a rotationally symmetrical manner outside the second water passage hole 52 as the first water passage hole 51. The first water passage hole 51 is an inclined hole, and the second water passage hole 52 is a straight hole.

[0037] The flow rate regulating mechanism 5 also includes a conical regulating mandrel 54 as the regulating component; the conical regulating mandrel 54 has a conical column on the side facing the second water passage 52; the conical column has a structure with a gradually increasing diameter from one end near the second water passage 52 to the other end.

[0038] The flow rate regulating mechanism 5 further includes an operating component 55 for driving the conical regulating spindle 54 to translate axially along the second water passage 52. The operating component 55 is disposed outside the water inlet spindle 6, and the water inlet spindle 6 is internally the water inlet channel 4; the side wall of the water inlet spindle 6 is provided with a relief groove 61 along the direction of translation of the conical regulating spindle 54; the operating component 55 is connected to the conical regulating spindle 54 through the relief groove 61.

[0039] In use, the conical adjusting spindle 54 is driven to move by pushing, twisting and sliding. The conical adjusting spindle 54 is a conical shaft that cooperates with the second water passage hole 52 of the inclined water body 53. When the conical adjusting spindle 54 slides, the water passage area of ​​the second water passage hole 52 of the inclined water body 53 is changed. With the area of ​​the first water passage hole 51 of the inclined water body 53 remaining unchanged, the flow of the first water passage hole 51 of the inclined water body 53 is diverted. The speed at which the water in the first water passage hole 51 of the inclined water body 53 impacts the impeller is changed, thereby changing the speed of the hydraulic pump 1, which in turn changes the speed at which the hydraulic pump 1 draws the functional liquid, thereby changing the concentration of the mixture of the functional liquid and the bath water.

[0040] This device can also achieve stepless adjustment of the concentration of functional liquids, specifically:

[0041] 1) When the beauty liquid needs to be drawn at the lowest speed, the operating part 55 needs to be pushed away from the second water passage 52. At this time, the tapered shaft of the tapered adjusting spindle 54 is completely separated from the second water passage 52 of the inclined water body 53. The tapered adjusting spindle 54 has no flow restriction effect on the second water passage 52 of the inclined water body 53. At this time, the second water passage 52 of the inclined water body 53 has the maximum flow diversion to the first water passage 51, the flow velocity of the first water passage 51 and the impact force on the impeller 14 are the minimum, and the hydraulic pump 1 draws the beauty liquid at the slowest speed.

[0042] 2) When it is necessary to extract the beauty liquid at a speed between the minimum and maximum speed, the operating part 55 can be pushed to any position in the middle except for the two ends. At this time, the tapered shaft of the tapered adjusting spindle 54 and the second water passage 52 of the inclined water body 53 cooperate with each other. The tapered adjusting spindle 54 has a flow-limiting effect on the second water passage 52 of the inclined water body 53. At this time, the second water passage 52 of the inclined water body 53 diverts the flow to the first water passage 51, reducing the water flow speed of the inclined water inlet and the impact force on the impeller 14, thereby reducing the speed at which the hydraulic pump 1 extracts the beauty liquid.

[0043] 3) When the beauty liquid needs to be drawn at the maximum speed, the push rod needs to be pushed to the end close to the second water passage 52. At this time, the conical shaft of the conical adjusting spindle 54 is basically in contact with the second water passage 52 of the inclined water body 53. The conical adjusting spindle 54 completely restricts the flow of the second water passage 52 of the inclined water body 53. At this time, the second water passage 52 of the inclined water body 53 will not divert the flow to the first water passage 51. At this time, the flow velocity of the first water passage 51 and the impact force on the impeller 14 are the greatest, and the hydraulic pump 1 draws the beauty liquid at the fastest speed.

[0044] In this embodiment, the functional liquid is a serum, conditioner, shampoo, or shower gel. When the water outlet is a spray gun or a kitchen shower head, the functional liquid can also be dish soap or hand soap.

[0045] The first water passage 51 connects to the water outlet channel 3 after passing through the impeller, and the second water passage 52 also connects to the water outlet channel 3. The amount of water flowing into the water outlet channel 3 after passing through the flow rate regulating mechanism 5 is the same as the amount flowing through the water inlet channel 4. Therefore, adjusting the flow rate of the beauty serum by regulating the outflow volume of the beauty serum through the flow rate regulating mechanism 5 achieves the purpose of regulating the concentration of the beauty serum.

[0046] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
