Abstract
Description
Technical Field
[0001] This utility model relates to the field of water-dispensing products, specifically to a water-dispensing component and a shower head. Background Technology
[0002] Existing shower heads and faucets have added scale inhibitors to prevent scale buildup. Shower systems typically contain scale inhibitors to achieve this purpose. After a certain period of use, users need to manually disassemble the scale inhibitor to replace it, which is quite troublesome. Scale inhibitors need to be replaced regularly, making them long-term consumables and resulting in high user costs. Existing copper-based catalyst alloy materials have low scale inhibition rates and unstable scale inhibition effects. For example, after a period of use, scale buildup on the material surface will also reduce the scale inhibition effect. Utility Model Content

The circuit board is adapted to convert the current generated by the power supply into a microcurrent. Its input and output terminals are electrically connected to the first and second electrode plates, respectively, and are adapted to form a circuit through the water in the water passage cavity. This allows the microcurrent to propagate in the water, releasing free electrons and causing a polarization effect, reducing the cation concentration in the water, thereby lowering the scale-forming index and affecting the nucleation and growth process of scale crystals, achieving a scale inhibition effect. Furthermore, under the action of the microcurrent, the scale and scale salt crystals in and on the inner wall of the water passage change from a marble structure to an aragonite structure, making them easier to decompose. The scale gradually falls off, achieving a descaling effect. This scale inhibition structure is electronic, requiring no disassembly or replacement, resulting in low cost.

[0022] 3. In Scheme 3 and its preferred embodiments, the opposing surfaces of the first electrode plate and the second electrode plate are non-planar, so that the opposing planes have a larger surface area, increasing the contact area with water. The larger the contact area with water flow, the better the scale inhibition speed and effect.

In Scheme 4 and its preferred embodiments, the surfaces of the first electrode sheet and the second electrode sheet facing each other are one or more of curved surfaces, wavy surfaces, and serrated surfaces, wherein the serrated surface has a sharp point, which has better discharge and conductivity effects.
[0024] 5. In Scheme 5 and its preferred embodiments, a hydroelectric generator is also included. The hydroelectric generator is a power source, which is installed on the main body and electrically connected to the circuit board. It is adapted to generate current when water flows through the water passage cavity to supply current to the circuit board. Hydroelectric power generation is cleaner and has lower daily operating costs.

[0026] 7. In Scheme 7 and its preferred embodiments, the first electrode plate and the second electrode plate are fixedly placed in the water passage cavity to prevent them from changing position due to hydraulic forces, which would lead to a deterioration in performance.
[0027] 8. In Scheme 8 and its preferred embodiments, the main body is provided with a limiting post and a snap-fit post located in the water passage cavity. There is an installation space between the limiting post and the snap-fit post. The limiting post and the snap-fit post are respectively provided with a first limiting surface and a second limiting surface. The first limiting surface and the second limiting surface are arranged opposite to each other. The snap-fit post is adapted to deform so as to allow the first electrode piece or the second electrode piece to be placed into the installation space, and is adapted to return to its original shape so that the two ends of the first electrode piece or the second electrode piece abut against the first limiting surface or the second limiting surface, thereby facilitating the installation of the first electrode piece or the second electrode piece, and maintaining the snap-fit state during use to prevent the first electrode piece or the second electrode piece from shaking.

[0045] Example 1,
[0046] refer to Figures 1-5 A shower head includes a water outlet assembly. In other embodiments, the water outlet assembly can also be applied to products such as faucets and spray guns.
[0047] The water outlet assembly includes a main body 1, a conductive component 2, a circuit board 3, and a hydroelectric generator 4.
[0048] refer to Figures 1-3 The main body 1 includes a handle portion 11 and a faceplate portion 12. The faceplate portion 12 has a water outlet 121. The handle portion 11 is used for gripping and has a water inlet 111 and a sealing cavity 112. The water passages of the handle portion 11 and the faceplate portion 12 enclose each other to form a water passage cavity 13. After the sealing element is installed, the sealing cavity 112 and the water passage cavity 13 are sealed and isolated from each other to prevent water in the water passage cavity 13 from entering the sealing cavity 112. The water passage cavity 13 is connected to the water inlet 111 and the water outlet 121. The sealing element can be a sealing ring, a sealing plug, a sealing gasket, or a potting layer (sealing is achieved through a potting process), etc.
[0049] refer to Figure 3The hydroelectric generator 4 is installed on the main body 1 and electrically connected to the circuit board 3 to supply current to the circuit board 3 as a power source. In this embodiment, the input end of the hydroelectric generator 4 is located in the water passage of the handle part 11, and generates current when water flows through the water passage chamber 13. The output end of the hydroelectric generator 4 is electrically connected to the circuit board 3 located in the sealed cavity 112 to supply current to the circuit board 3 as a power source. In other embodiments, the circuit board 3 can also be powered by a battery or mains power. The hydroelectric generator 4 can be a turbine generator, etc., which will not be described in detail here.
[0050] refer to Figures 2-5 The conductive component 2 is adapted to conduct electricity and includes a first electrode plate 21 and a second electrode plate 22. The first electrode plate 21 and the second electrode plate 22 are spaced apart and placed in the water passage cavity 13. In this embodiment, there are at least two conductive components 2, which are located in the water passages of the handle portion 11 and the cover portion 12, respectively, to descale the two main water passages. The first electrode plate 21 and the second electrode plate 22 extend along the water passage direction to ensure a large length and increase the contact area with water. The opposing surfaces of the first electrode plate 21 and the second electrode plate 22 are non-planar to have a larger surface area relative to the vertical plane, increasing the contact area with water. The larger the contact area with the water flow, the better the scale inhibition speed and effect. Specifically, the opposing surfaces of the first electrode plate 21 and the second electrode plate 22 are one or more of curved surfaces, wavy surfaces, and serrated surfaces 23. In this embodiment, the opposing surfaces of the first electrode plate 21 and the second electrode plate 22 are serrated surfaces 23, which have sharp points and better discharge and conductivity effects. The first electrode plate 21 and the second electrode plate 22 are fixedly placed inside the water passage cavity 13 to ensure stable operation. For details, please refer to... Figure 4 The cross-sections of the first electrode plate 21 and the second electrode plate 22 located within the faceplate portion 12 (perpendicular to the arrangement direction of the handle portion 11 and the faceplate portion 12) are approximately L-shaped, having a horizontal portion and a vertical portion perpendicular to each other. The vertical portion is parallel to the water outlet direction of the water outlet 121. The body 1 is provided with a limiting post 14 and a locking post 15 located within the water passage cavity 13. Multiple sets of limiting posts 14 and locking posts 15 can be provided. The projections of the limiting posts 14 and locking posts 15 onto a plane perpendicular to the water outlet direction of the water outlet 121 can overlap or be staggered (e.g., ...). Figure 5 As shown, the two are offset from each other. There is an installation space 16 between the limiting post 14 and the snap-fit post 15, as shown. Figure 4As shown, the installation space 16 is also L-shaped, including a vertical section and a horizontal section that are perpendicular to each other. The vertical section is parallel to the water outlet direction of the outlet 121. The limiting post 14 and the snap-fit post 15 are respectively provided with a first limiting surface 141 and a second limiting surface 151 corresponding to the horizontal section of the installation space 16. The first limiting surface 141 and the second limiting surface 151 are arranged opposite to each other and perpendicular to the water outlet direction of the outlet 121. The locking post 15 is provided with an elastic hook (the second limiting surface 151 is located on the elastic hook) to allow the locking post 15 to deform when the first electrode piece 21 or the second electrode piece 22 abuts against the inclined surface of the elastic hook, thereby allowing the first electrode piece 21 or the second electrode piece 22 to pass over the elastic hook and be placed into the installation space 16. At this time, the first electrode piece 21 or the second electrode piece 22 no longer acts on the elastic hook, and the locking post 15 returns to its original position, so that the two ends of the first electrode piece 21 or the second electrode piece 22 along the water outlet 121 respectively contact the first limiting surface 141 or the second limiting surface 151. The limiting surfaces 151 abut against each other, thereby achieving the snap-fit installation of the first electrode piece 21 or the second electrode piece 22. Preferably, the vertical section corresponding to the installation space 16 between the snap-fit post 15 and the limiting post 14 is further provided with a third limiting surface 142 and a fourth limiting surface 152 arranged opposite to each other. The third limiting surface 142 is perpendicular to the first limiting surface 141 and is arranged opposite to the fourth limiting surface 152. When the first electrode piece 21 or the second electrode piece 22 is installed, the first electrode piece 21 or the second electrode piece 22 also abuts against the third limiting surface 142 and the fourth limiting surface 152 to prevent shaking. Of course, in other embodiments, the first electrode piece 21 or the second electrode piece 22 can also be fixed to the body 1 by means of screw connection, adhesive bonding, etc. The installation method of the first electrode piece 21 or the second electrode piece 22 can be the same or different. The installation method of different groups of conductive components and the structure of the first electrode piece 21 or the second electrode piece 22 can be the same or different.
[0051] The first electrode plate 21 and the second electrode plate 22 are made of metallic conductive materials, such as stainless steel, copper, iron, silver, etc. Preferably, copper plated with nickel has better performance (good conductivity and is not easy to oxidize).
[0052] refer to Figure 3The circuit board 3 is placed inside the sealed cavity 112 and is adapted to convert the current generated by the power supply into a microcurrent. The input and output terminals of the circuit board 3 are electrically connected to the first electrode plate 21 and the second electrode plate 22, respectively, and are adapted to form a circuit through the water in the water cavity 13, thereby allowing the microcurrent to propagate in the water. Under the action of the current, free electrons are released into the water, causing a polarization effect in the water, reducing the cation concentration in the water, thereby reducing the scaling index, affecting the nucleation and growth process of scale crystals, and achieving a scale inhibition effect. Furthermore, under the action of the microcurrent, the scale and scale salt crystals in the water cavity and on the inner wall of the water cavity change from a marble structure to an aragonite structure, which is easier to decompose, and the scale gradually falls off, achieving a descaling effect. The circuit board 3 can obtain electrical energy from the power supply and convert it into a precisely controlled microcurrent (usually in the microampere μA to milliampere mA level) by designing specific circuits (such as using resistor current limiting, constant current source circuit, etc.). Preferably, the intensity of the microcurrent emitted by the circuit board 3 is adjustable to adjust the descaling intensity. The stronger the microcurrent generated, the better the speed and effect of scale inhibition.
[0053] When using, refer to Figures 1-5 When water begins to flow through the water passage 13, the hydroelectric generator 4 starts generating electricity, and the current flows into the circuit board 3. The circuit board 3 converts the current into a microcurrent. The input and output terminals of the circuit board 3 are electrically connected to the first electrode plate 21 and the second electrode plate 22, respectively, and are adapted to form a circuit through the water in the water passage 13. Under the action of the microcurrent, the water achieves the effects of scale inhibition and scale removal. The scaled impurities flow out through the water outlet 121 through the water in the water passage 13. This scheme achieves the effect of scale inhibition on the basis of scale removal, resulting in less scale.
