[0038] The present utility model provides a power generation device for a floor washer and a floor washer that increase the battery life of the floor washer to improve the user experience.

[0039] The following combinationFigures 1 to 6 A more detailed description of the technical solution provided by the present utility model will be given.

[0040] The present utility model provides a power generation device for a floor washer, including:

[0041] A power generation housing 100;

[0042] A traveling wheel 130, the rotating shaft 140 of the traveling wheel 130 is rotatably arranged in the power generation housing 100, a rotor assembly 150 is arranged on the rotating shaft 140, a stator assembly 160 is arranged on the inner wall of the power generation housing 100, the stator assembly 160 and the rotor assembly 150 are coaxially arranged, and the stator assembly 160 is arranged in a ring shape around the rotor assembly 150;

[0043] When the traveling wheel 130 rotates, it drives the rotor assembly 150 to rotate, so that the stator assembly 160 and the rotor assembly 150 rotate relative to each other to generate an electric current.

[0044] The power generation device for a floor washer provided by the present utility model includes a power generation housing 100 and a traveling wheel 130. The rotating shaft 140 of the traveling wheel 130 is rotatably arranged in the power generation housing 100. A rotor assembly 150 is arranged on the rotating shaft 140. A stator assembly 160 is arranged on the inner wall of the power generation housing 100. The stator assembly 160 and the rotor assembly 150 constitute a power generation mechanism. When using the floor washer, push the handle of the floor washer, the traveling wheel 130 rolls along the ground, drives the rotor assembly 150 to rotate, and utilizes the relative movement of the rotor assembly 150 and the stator assembly 160 of the generator to cut the magnetic induction lines to generate an electric current. Then, the generated electric current is rectified and regulated by an electronic circuit to charge the battery of the floor washer, thereby increasing the battery life of the floor washer and improving the user experience.

[0045] It can be understood that the rotor assembly 150 includes a permanent magnet, and the stator assembly 160 includes a winding coil. The rotor assembly 150 and the stator assembly 160 move relative to each other to cut the magnetic induction lines to generate an electric current, realizing the power generation of the generator.

[0046] It should be noted that since the floor washer will move forward or backward as the user uses it, correspondingly, the traveling wheel 130 will rotate clockwise or counterclockwise. Whether the traveling wheel 130 rotates clockwise or counterclockwise, the rotor assembly 150 and the stator assembly 160 will move relative to each other to cut the magnetic induction lines to generate an electric current. And because the floor washer is dragged back and forth, the direction of the electric current will also change at any time. Therefore, the electric current needs to be rectified and regulated by an electronic circuit before being used to charge the battery, thereby increasing the battery life.

[0047] In some embodiments of the present utility model, a cooling fan 190 is further arranged on the rotating shaft 140 of the traveling wheel 130.

[0048] In some of the above embodiments of the present utility model, a cooling fan 190 is provided on the rotating shaft 140. The cooling fan 190 can rotate with the rotating shaft 140. The cooling fan 190 can be used to dissipate heat from the stator assembly 160, rotor assembly 150, etc. inside the power generation housing 100, improving the power generation effect.

[0049] In some embodiments of the present utility model, the cooling fan 190 includes a fan shaft sleeve 200 and a plurality of fan blades 210. The plurality of fan blades 210 are arranged in a circular array on the fan shaft sleeve 200;

[0050] The fan blades 210 are symmetrically provided with wind-disturbing inclined surface structures 220. The wind-disturbing inclined surface structures 220 are symmetrically arranged along the radial direction of the fan shaft sleeve 200.

[0051] In some of the above embodiments of the present utility model, the cooling fan 190 includes a fan shaft sleeve 200 and a plurality of fan blades 210. The fan shaft sleeve 200 is connected to the rotating shaft 140 of the walking wheel 130. The fan shaft sleeve 200 is sleeved on the rotating shaft 140. The fan blades 210 are symmetrically provided with wind-disturbing inclined surface structures 220 along the radial direction of the fan shaft sleeve 200. The wind-disturbing inclined surface structures 220 are used to achieve the air supply function. The wind-disturbing inclined surface structures 220 are symmetrically arranged, and can play the air supply role when the rotating shaft 140 rotates clockwise or counterclockwise, thus effectively ensuring the heat dissipation effect of the cooling fan 190.

[0052] It should be noted that the wind-disturbing inclined surface structures 220 are symmetrically arranged along the radial direction of the fan shaft sleeve 200, which means symmetrically arranged with the plane where the radial direction of the fan shaft sleeve 200 is located as the central plane, forming fan blades 210 with a V-shaped structure. When the fan blades 210 rotate clockwise or counterclockwise, the two wind-disturbing inclined surface structures 220 on the fan blades 210 can respectively serve as wind-disturbing pressure surfaces to achieve the air supply purpose and dissipate heat from the stator assembly 160 inside the heat dissipation housing.

[0053] It can be understood that the wind-disturbing inclined surface structures 220 can also be asymmetric structures. The wind-disturbing inclined surface structures 220 on both sides of the fan blades 210 are respectively used for air supply when rotating clockwise or counterclockwise to dissipate heat from the stator assembly 160.

[0054] In some embodiments of the present utility model, an air inlet 170 and an air outlet 180 are provided on the power generation housing 100. The air inlet 170 and the air outlet 180 are respectively arranged on both sides of the cooling fan 190.

Under the action of the cooling fan 190, external cold air enters the power generation housing 100 through the air inlet 170 and blows to the other side of the cooling fan 190, thereby forming a cooling air flow in the power generation housing 100 to dissipate heat from the stator assembly 160 in the power generation housing 100.

[0056] Preferably, the stator assembly 160 is arranged between the air outlet 180 and the cooling fan 190. Under the action of the cooling fan 190, external cold air enters the power generation housing 100 through the air inlet 170 and directly blows to the stator assembly 160, and after dissipating heat from the stator assembly 160, it is discharged from the air outlet 180, improving the heat dissipation effect of the stator assembly 160.

When the fan blades 210 rotate, after the external cold air enters the heat dissipation housing, it is disturbed by the fan blades 210 and evenly diverges towards the inner wall direction of the power generation housing 100 and blows to the stator assembly 160, making the blowing more uniform and improving the heat dissipation effect of the stator assembly 160.

[0059] In some embodiments of the present utility model, the air outlets 180 are annularly arrayed on the side wall of the power generation housing 100.

[0060] In some of the above embodiments of the present utility model, the air outlet 180 is arranged on the side wall of the power generation housing 100, and the air blown out by the cooling fan 190 is discharged through the air outlet 180 on the side wall of the power generation housing 100, which can increase the contact between the air and the side wall of the power generation housing 100 and improve the heat dissipation effect of the inner wall of the power generation housing 100 and the stator assembly 160.

[0061] In some embodiments of the present utility model, the power generation housing 100 includes a power generation outer shell 110 and a power generation cover plate 120, and the power generation cover plate 120 covers the opening of the power generation outer shell 110;

[0062] The rotating shaft 140 of the traveling wheel 130 passes through the power generation outer shell 110 and is rotatably arranged on the power generation housing 100 and the power generation cover plate 120;

[0063] The air inlet 170 is provided on the power generation cover plate 120, and the air outlet 180 is provided on the power generation housing 110.
