The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Referring to fig. 1-7, the present invention provides an embodiment: a micro water flow generator comprises a shell 1, wherein a generator 4 is arranged inside the shell 1, and one end of the generator 4 penetrates through the shell 1 and then is connected with an impeller 2; the shell 1 is also provided with a first water inlet 13 and a second water inlet 14, and water flow is guided to impact the impeller 2 through the first water inlet 13 or the second water inlet 14, so that the generator 4 generates electricity.

In summary, two water inlets are provided, one of the two water inlets is located on the side surface of the housing 1 and impacts the impeller 2, and the other water inlet is located on the end surface of the housing 1 and impacts the impeller 2; therefore, when the device is installed on a water faucet, when the first water inlet 13 is used for water inflow, the second water inlet 14 is used for water outflow, the impeller 2 can rotate at the moment, and when the second water inlet 14 is used for water inflow, the first water inlet 13 is used for water outflow, and the impeller 2 can also rotate. Therefore, the device can utilize water flow to drive the impeller 2 to rotate under the condition of any water outlet mode so as to realize the power generation of the generator 4. Thereby improving the general performance of the equipment.

On the basis of the above scheme, because the one end of the casing 1 far away from the generator 4 is further provided with the filter housing 3, and through the connection of the filter housing 3 and the casing 1, impurities are prevented from flowing into the casing 1 through the first water inlet 13 or the second water inlet 14, so that the impurities in water can be filtered by using the filter housing 3 to avoid the problem that the rotation of the impeller 2 is blocked due to the contact of the impurities with the impeller 2.

In addition, two water inlets both can intake also can go out water, so can wash filter mantle 3 through the reverse flow of water source, realize washing to avoid impurity to block up the problem that causes the velocity of flow of water to slow down, for example, pull down tap's water inlet, then pour into the water source from tap's delivery port, both can accomplish washing of filter mantle 3.

The specific design mode can be as follows: the first water inlet 13 is located at a side of the impeller 2 and introduces water flow into the interior of the housing 1 from different angles through the inclined surface 16 to urge the water flow into the housing 1 in a predetermined direction so that the water flow entering the interior of the housing 1 impinges on the impeller 2. Because the inclined plane 16 is provided with the extension lines b, an included angle a is formed between the intersection points of any two extension lines b; the included angle a is an acute angle as long as the water flow can directly impact the impeller 2; for example, when the included angle a is 60 degrees, the force of the water flow impacting the impeller 2 can be forced to be strongest, so that the rotation efficiency of the impeller 2 can be maximized.

For further promotion impeller 2's rotational efficiency, impeller 2 top is equipped with and hinders the surface 20, and the water impact hinders the rotation that the surface can better impel impeller 2, and the lower part of impeller 2 is equipped with drainage face 21, and through the centrifugal pump principle, the second water inlet 14 that lies in the impeller 2 below can be better got rid of through impeller 2 to rivers simultaneously, flows out from second water inlet 14. Wherein, the choked flow surface 20 and the induced flow surface 21 are integrally processed.

Further, the inner wall surface of the second water inlet 14 is a conical surface 37, that is, the inner wall surface of the second water inlet 14 is folded from the surface facing the bottom net 34 to the surface facing the impeller 2 until the inner wall surface is folded to the water hole 38, so that when water enters the second water inlet 14, the folded water flow of the conical surface 37 can be used for enhancing the water pressure, so as to enhance the rotation efficiency of the impeller 2;

the back of second water inlet 14 still is equipped with water drainage tank 36, when first water inlet 13 intakes, when rivers flow to second water inlet 14 department, after rivers process water hole 38, the area of delivery that reduces of water hole 38, water area is put once more to toper face 37, recycle the inside siphon principle in water route, so can make the rivers that flow form the vortex this kind of suction of vortex formula this kind promptly, accelerate its displacement, and then can effectually strengthen the suction of second water inlet 14, the water in the discharge housing 1 that can be as fast as far as possible, the generating efficiency of motor 4 is improved.

Meanwhile, when water enters from the second water inlet 14, the water flow impacts the impeller 2 to enable the impeller 2 to rotate, water in the water drainage groove 36 forms a vortex leading to the impeller 2, the flow speed of the water in the water drainage groove 36 can be effectively enhanced through the suction force of the water flow at the second water inlet 14, the water flow in the water drainage groove 36 is enabled to upwards impact the impeller 2, and the power generation efficiency of the motor 4 is further enhanced.

Specifically, the filter housing 3 comprises a side net 31 sleeved outside the first water inlet 13 and a bottom net 34 covering the second water inlet 14.

Furthermore, one end of the side net 31 is connected with the bottom cover 30, and the bottom cover 30 is connected with the bottom net 34 through the supporting column 32, so that the filter housing 3 forms a whole, and the assembled filter housing 3 is conveniently connected with the shell 1.

Furthermore, because the bottom cover 30 is further provided with a groove 35 on the side facing the bottom net 34, and the groove 35 is in adaptive connection with the provided sealing ring 33, the sealing ring 33 can be utilized to seal the connection between the device and the faucet, and meanwhile, the replacement of the sealing ring 33 is also facilitated.

On the basis of the above scheme, the casing 1 is further provided with a flow guide surface 12, and the flow guide surface 12 guides water flow to enter the casing 1 through the first water inlet 13. Due to the arrangement of the flow guide surface 12, after the housing 1 and the faucet are installed, a larger water storage area is arranged between the flow guide surface 12 and the inner wall of the faucet, so that a water source can stably impact the impeller 2, meanwhile, the flow guide surface 12 and the first water inlet 13 are integrally formed, namely, the first water inlet 13 directly penetrates through the housing 1 along the radian of the flow guide surface 12, and therefore, the first water inlet 13 is convenient to process, and meanwhile, water flow can be guaranteed to directly impact the impeller 2.

Specifically, still be equipped with external screw thread 11 on the casing 1, just external screw thread 11 is located the top of water conservancy diversion face 12, and through external screw thread 11 will casing 1 is fixed on the tap, consequently makes casing 1 and tap simple to operate.

Further, the shell 1 is further provided with an annular groove 10, and the annular groove 10 is located above the external thread 11, so that the upper end of the shell 1 can be sealed, and meanwhile, the shell 1 can be screwed on a water faucet by using the driving part 15. Wherein the cross section of the driving part 15 is hexagonal.

In addition, the temperature-sensing probe in the shell 1 is made of electrolytic copper materials, so that magnetization is effectively prevented, the service life is prolonged, and meanwhile, the chromium coating is arranged on the surface of the temperature-sensing probe, so that oxidation corrosion is further prevented.
