The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-4, the present invention provides an embodiment: a generator for a faucet comprises a main body part 3, an end cover 2 connected with the main body part 3; the structure and the specific connection mode can directly adopt the structure of the existing generator assembly, for example, a stator and a rotor are arranged inside the main body part 1 or a generator is directly arranged in the main body part 1.

The main body part 3 is internally provided with a generator assembly 4 and an impeller 1 for driving the generator assembly 4 to rotate; the end cover 2 is provided with a first water inlet 22 for guiding water flow to impact the side surface of the impeller 1; the impeller 1 is driven to rotate from the side surface through the first water inlet 22, the generator component 4 is driven to generate electricity, and the electricity generation function is realized while the water flow is realized; wherein the impeller 1 may be mounted on the shaft of the rotor, or on the motor shaft when a generator is used.

The end cover 2 is further provided with a second water inlet 20 for guiding water flow to cover the upper end face of the impeller 1, and the second water inlet 20 enables the water flow to enter from the upper end of the impeller 1, so that the impeller 1 in stable rotation by the flow of the water flow is prevented from shaking on a motor shaft.

In summary, because the second water inlet 20 guides the water flow to the upper end surface of the impeller 1, the pressure of the water flow can be used to overcome the up-and-down swing of the impeller 1 on the motor shaft, so that the problem that the gap between the impeller 1 and the motor shaft is enlarged due to shaking is avoided; and the impeller 1 is balanced in stress, so that the impeller can stably rotate, and the power generation efficiency of the power generator assembly 4 is greatly improved.

In order to further stabilize the impeller 1 and ensure the stress balance of the impeller 1, the second water inlet 20 guides the water flow to the upper end surface of the impeller 1 through the inclined surface 21, and the inclined surface 21 guides the water flow to obliquely enter the upper end of the impeller 1, so that the impeller 1 can be balanced on the motor shaft in a large range by the water flow.

Furthermore, the inflow direction of the water flow guided by the inclined surface 21 is consistent with the rotation direction of the impeller 1, so that the resistance of the impeller 1 during rotation can be further reduced, and the water flow entering through the second water inlet 20 can further promote the impeller 1 to rotate, so that the potential energy of the water flow is fully utilized, the conversion efficiency of the potential energy to the mechanical energy is improved, and the power generation efficiency of the generator assembly 4 is higher.

In order to solve the problem that the water source is accumulated in the main body part 3 due to long water flow stroke and the conversion efficiency of potential energy is influenced, the main body part 3 is further provided with a water outlet 32, the water outlet 32 is provided with a groove surface 31 for shortening the flow stroke of the water flow, the arrangement of the groove surface 31 shortens the water flow stroke, enhances the flow quantity of the water flow to enable the water source to be quickly discharged from the main body part 3, further enhances the rotating speed of the impeller 1, and solves the problems that the rotation of the impeller 1 is blocked or the rotating resistance of the impeller 1 is large due to unsmooth water discharge.

Further, one end of the main body portion 3 is provided with a cavity 30 for accommodating the impeller 1, wherein the groove surface 31 is disposed on an outer side surface of the cavity 30 and extends toward the inside of the cavity 30. Through the above scheme, the groove surface 31 extends towards the inside of the cavity 30, the flow stroke of water flow is shortened, namely, the water flow can flow downwards or can flow along the radial direction of the cavity 30, the flow direction of the water flow is increased, so that a water source in the cavity 30 is rapidly discharged, and the rotation efficiency of the impeller 1 is improved.

In addition, the other end of the main body part 1 opposite to the cavity 30 can be provided with a cavity for accommodating the generator assembly 4, so that the generator assembly 4 can be hidden in the main body part 1.

Furthermore, the number of the water outlets 32 is equal to the number of the groove surfaces 31, so that the flow direction of the water flow is more, for example, four, and at this time, the flow direction of the water flow can flow in a radial direction at least in four directions and can also flow downwards after flowing in the radial direction; meanwhile, the water source extends towards the inner side, so that the water storage capacity outside the main body part 3 is more, and the water source flowing out from the cavity 30 is faster.

Because the water outlet 32 is further provided with the mounting hole 33 for mounting the sensor, the position of the sensor can be closer to the water outlet 32, so that the value detected by the sensor is more accurate, for example, a temperature sensor is mounted, and at the moment, the discharge temperature of the water source can be sensed more accurately because the temperature sensor is closer to the water outlet 32.

In order to realize more stability of the impeller 1, the impeller 1 comprises blades 10, a guide surface 11 is arranged between every two blades 10, and a water source is guided by the guide surface 11, so that the pressure of the water source can be uniformly concentrated on the guide surface 11, and the pressure is used for balancing the up-and-down shake of the impeller 1 on the shaft.

Furthermore, one end of the flow guide surface 11 is in contact with a bottom plate 12 provided with the flow guide surface, the other end of the flow guide surface is in contact with an axle pin 13 provided with the flow guide surface, and the flow guide surface 11 extends from one end of the bottom plate 12 to one end of the axle pin 13 in an inclined manner, so that the blades 10 are effectively fixed through the arrangement of the bottom plate 12 and the axle pin 13, and the bottom plate 12 further guides water to flow in an inclined manner and then flow out along the radial direction of the bottom plate 12, so that the impeller 1 is further stabilized.
