As shown in FIGS. 1-4 , in one or more embodiments, the washing device is a washing machine 1, and the washing machine 1 includes a housing 11, an air duct 12, a fan 13, a washing tub 33 accommodated in the housing 11, Solenoid valve 31 , water inlet pipe 32 and detergent box 34 . As shown in FIG. 1 , in one or more embodiments, both ends of the water inlet pipe 32 are respectively connected to an external water source and a detergent box 34 for injecting washing water into the washing tub 33 . The detergent box 34 is used for containing detergent and communicated with the washing tub 33 . When the washing machine 1 is washing, the control system controls the solenoid valve 31 to allow water from an external water source to enter the water inlet pipe 32 , and inject washing water into the washing tub 33 through the detergent box 32 . A fan 13 is provided at the upper portion of the washing machine 1, and the fan 13 is arranged in a substantially horizontal direction (based on the direction shown in Fig. 1). The fan 13 communicates with the washing tub 33 through the air duct 12 . The fan 13 includes a motor 132 and a fan blade 131 . The fan blades 131 are evenly distributed along the circumferential direction of the fan 13 and extend along the radial direction of the fan 13 . When the fan 13 works, the motor 132 drives the fan blades 131 to rotate, and the washing tub 33 is ventilated through the air duct 12 .

As shown in FIG. 1 , in one or more embodiments, a first self-generating module 14 is provided on the fan blade 131 , and the first self-generating module 14 is also electrically connected with a first sterilizing component 15 . The first disinfection assembly 15 may be configured to include, but not limited to, an ultraviolet lamp or a deep ultraviolet lamp. Alternatively, the first disinfection component 15 may be replaced with a lighting component, such as an LED lamp, or a disinfection component and a lighting component may be provided at the same time.

Fig. 2 is a schematic plan view of the first embodiment of the electrical connection between the self-generating module and the sterilizing assembly of the washing device of the present invention. As shown in FIG. 2 , in one or more embodiments, the first self-generating component 14 includes a guide portion 141 , a coil 143 and a magnetic member 142 . The guide portion 141 has a substantially rectangular parallelepiped shape. Alternatively, the guide portion 141 can also adopt other suitable shapes, such as a hollow long cylinder. The guide portion 141 has opposite guide portion first ends 141 a and guide portion second ends 141 b along its longitudinal direction (horizontal direction shown in FIG. 2 ). The inside of the guide portion 141 is a cavity structure, and the inner surface of the cavity structure is set as a smooth surface. The magnetic member 142 is accommodated in the cavity structure inside the guide portion 141 and is allowed to move freely in the longitudinal direction thereof in the inner cavity structure.

As shown in FIG. 2 , in one or more embodiments, the magnetic member 142 is a rectangular body with a smooth surface adapted to the shape of the inner cavity of the guide portion 141 , and the first end 141 a of the guide portion and the second end of the guide portion 141 141b can move freely between them. Herein, the free movement of the magnetic member 142 between the first end 141a of the guide portion and the second end 141b of the guide portion is referred to as "reciprocating motion C". Setting the inner surface of the guide portion 141 as a smooth surface and setting the outer surface of the magnetic member 142 as a smooth surface can reduce the frictional resistance experienced by the magnetic member 142 when the magnetic member 142 reciprocates inside the guide portion 141 to increase the speed of the reciprocating motion.

In addition, those skilled in the art can also provide elastic spacers (not shown in the figure) inside the guide part 141 at the first end 141a of the guide part and the second end 141b of the guide part (not shown in the figure) to slow down the magnetic parts as required.

The reciprocating motion of the magnetic member 142 inside the guide portion 141 can cause a current to be generated in the coil 143 wound on the outside of the guide portion 141 , that is, the principle of magnetism is used. The speed and frequency of the reciprocating motion can affect the magnitude of the current in the coil 143 . As shown in FIG. 2 , in one or more embodiments, the coil 143 is connected with the first sterilizing assembly 15 through a wire 181 to provide power for the first sterilizing assembly 15 .

FIG. 3 is a schematic plan view of the second embodiment of the electrical connection between the self-generating module and the sterilizing assembly of the washing apparatus of the present invention. As shown in FIG. 3 , in another alternative embodiment, a circuit board 182 is provided between the first self-generating module 14 and the first sterilizing assembly 15 . Specifically, the coil 143 is connected to the circuit board 182 through the wire 181 , and the first sterilizing component 15 is connected to the circuit board 182 . Since the reciprocating motion of the magnetic member 142 inside the guide portion 141 is intermittent and unstable, with an unfixed speed and frequency, the magnitude of the current in the coil 143 is also unstable. The circuit board 182 is configured to control the voltage to prevent transient high voltages from being applied to the first sterilization assembly 15 . By arranging the circuit board 182 between the coil 143 and the sterilizing assembly 15 , the voltage supplied to the first sterilizing assembly 15 can be more stable, thereby prolonging the service life of the first sterilizing assembly 15 .

4 is a schematic plan view of a third embodiment of the electrical connection between the self-generating module and the sterilizing assembly of the washing device of the present invention.

Based on the direction shown in FIG. 5, in the vertical direction (direction perpendicular to the paper surface), the first end 141a of the guide portion is disposed at a position lower than the second end 141b of the guide portion.

Preferably, the fan 13 has an intermittent working mode, and in the intermittent working mode, it can intermittently work with high frequency. When the fan 13 rotates at a high speed, the magnetic member 142 in the first self-generating module 14 provided on the fan blade 131 will move in the interior of the guide portion 141 due to centrifugal force and abut against the end of the second end 141b of the guide portion . When the fan 13 stops rotating, the magnetic member 142 will move to the end of the first end 141a of the guide portion due to the action of gravity. The above-mentioned moving process of the magnetic member 142 causes the coil 143 to cut the magnetic induction line to generate a current in the coil 143 . Since the fan 13 is provided as a spaced working element, the magnetic member 142 can reciprocate inside the guide portion 141 to generate electricity in the coil 143 .
