Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic generators, and in particular relates to a double-waterway hydraulic generator and a water outlet device. Background Art

[0002] A hydroelectric generator is a device that uses the impact force of water flow to drive the impeller of a water turbine to rotate, and then transfers the mechanical energy generated by the rotation of the water turbine to a generator. The generator converts the mechanical energy into electrical energy under the action of magnetic induction. Hydroelectric generators are widely used in the bathroom field. For example, they are installed on showers and basin faucets. The product can generate electrical energy during normal use to supply other power-consuming components. At present, most of the micro-hydraulic generators on the market are single-channel generators, that is, all the water flow at the water inlet is used to impact the impeller to generate electricity. When the water pressure at the water inlet is very high, the impeller will be subjected to a large impact force. Although the power generation of the generator is increased, it exceeds the power demand of the shower product.

Preferably, the spring piece 4 is a corrosion-resistant 304 stainless steel sheet with good elastic deformation. The plane of the elastic deformation part 41 is in close contact with the upper end surface of the first water passage 120. To ensure that the elastic deformation part 41 is in sealing contact with the water outlet of the first water passage 120 in the initial state, a second sealing ring 7 is provided on the water outlet of the first water passage 120. The lower surface of the spring piece 4 presses the second sealing ring 7 downward to seal the water outlet of the first water passage 120. In this embodiment, the first sealing ring 6 and the second sealing ring 7 are both made of rubber.

[0035] For details, see Figure 2-Figure 7 In this embodiment, the spring sheet 4 is fixed between the upper shell 21 and the lower shell 22, and a plurality of spring sheet fixing parts 42 are arranged at intervals. The lower shell 22 is provided with a limiting groove 220 corresponding to the spring sheet fixing part 42, and the upper shell 21 is provided with a limiting boss 210 corresponding to the limiting groove 220.

[0038] For details, see Figure 5-Figure 8 In this embodiment, the water flow guide baffle 222 includes a first guide plate 2220 and a second guide plate 2221 connected to the side of the first guide plate 2220, the second guide plate 2221 extends to the top of the water outlet chamber 211, the height of the first guide plate 2220 is lower than the height of the second guide plate 2221, the drainage channel 212 includes a first drainage channel 2120 connected to the water inlet chamber 221, and a second drainage channel 2121 connected to the first drainage channel 2120, the second drainage channel 2121 is connected to the injection port 5, the first drainage channel 2120 is vertically arranged, and the second drainage channel 2121 is horizontally arranged. In this embodiment, there are two second water passages 121 and four water flow guide baffles 222. The two water flow guide baffles 222 divide each second water passage 121 into two diversion channels 212. After water flows into the water inlet channel 11, it flows into the second water passages 121 on both sides, and then flows into the injection port 5 through the four diversion channels 212, and is injected onto the impeller 31 through the injection port 5. The cross-sectional area of ​​each injection port 5 is smaller than the cross-sectional area of ​​the first diversion channel 2120 and the second diversion channel 2121. This structure allows the water flow in the channel to be quickly diverted to the injection port 5, and then impacts the impeller 31 after being pressurized through the injection port 5. The first guide plate 2220 and the second guide plate 2221 are integrally formed, the first drainage channel 2120 and the second drainage channel 2121 form an inverted L-shaped drainage channel 212, the two side surfaces of the jet port 5 are the jet port inclined surfaces 51, the bottom surface of the second drainage channel 2121 is flush with the jet port bottom surface 52 of the jet port 5, the inclined surface 21210 of the second drainage channel 2121 and the jet port inclined surface 51 are on the same plane, and the second drainage channel 2121 and the jet port 5 are designed to be flush surfaces, which can ensure that the drainage channel 212 through which the water flows is a smooth surface, and the water flows more smoothly. At the same time, the design of the inclined surface can enable the water sprayed from the jet port 5 to impact the impeller 31 at the most efficient spray angle, thereby improving the working efficiency of the generator.

[0039] For details, see Figure 7-Figure 8 In this embodiment, the injection directions of the multiple injection ports 5 are arranged in a ring shape, and the inlet water flows out along the injection direction of the injection ports 5 to effectively impact the impeller 31, so that the impeller 31 rotates more efficiently.

After the inlet water flows through the injection port 5 and impacts the impeller 31, it flows into the mixed water outlet channel 122 from the first water outlet hole 213 and is discharged.

[0041] For details, see Figure 2 In this embodiment, a buckle boss 214 is provided on the outer wall of the upper shell 21, and a buckle slot plate 32 adapted to the buckle boss 214 is provided on the outer wall of the hydroelectric power generation component 3. In this embodiment, the buckle boss 214 is buckled with the buckle slot plate 32 to realize the rapid assembly of the power generation component 3 and the upper shell 21, with a simple structure and convenient installation. The utility model does not limit the connection method between the upper shell 21 and the power generation component 3, as long as the fixed connection between the two can be achieved, and those skilled in the art can design it by themselves.

[0042] The utility model also provides a water outlet device, including a dual-waterway hydraulic generator, wherein the water inlet of the water outlet device is connected to the water inlet channel of the dual-waterway hydraulic generator, and the water outlet is connected to the water outlet channel. The water outlet device is not limited here, and any product that can have water flow in and out can use the dual-waterway hydraulic generator to generate electricity. Currently, it is more common to install the dual-waterway hydraulic generator in bathroom products such as showers, kitchen faucets, basin faucets, toilet water inlets and water heaters, generate electricity through water power, and supply the generated electricity to the power-consuming components of the water outlet device.

[0043] The working principle of the dual-channel hydraulic generator of the present application is as follows: in the initial state, the elastic deformation part 41 of the spring 4 abuts against the water outlet of the first water passage 120. When the water pressure of the inlet water is less than the preset water pressure, the elastic deformation part 41 remains stationary, and the inlet water flows into the water inlet chamber 221 and the water outlet chamber 211 in sequence through the water inlet channel 11, and flows into the injection port 5 through the first drainage channel 2120 and the second drainage channel 2121 for pressurization. The pressurized water flow impacts the impeller 31, so that the power generation component 3 generates electricity, and the falling water flows into the mixed water outlet channel 213 through the first water outlet hole 213. When the water pressure reaches the preset pressure, the elastic deformation part 41 of the spring piece 4 is deformed upward, and a part of the water flow flows in the above manner to make the power generation component 3 generate electricity, and the other part of the water flows into the second water outlet hole 223 through the first water passage 120, and flows into the water outlet channel 13 through the mixed water outlet channel 122 for discharge. When the water pressure decreases, the elastic deformation part 41 of the spring piece 4 is reset under its own elastic action, and the first water passage 120 is closed again, and this is repeated to complete the power generation of the dual-channel hydraulic generator.
