[0046] Example

[0047] Reference Figure 1-Figure 9, which is an embodiment of the present invention, provides a fan that is easy to clean the fan blades, including: a fan equipment unit 100, a water spray unit 200, a foam spray unit 300 and an auxiliary unit 400;

[0048] The fan device unit 100 includes a housing 101 and an air outlet pipe 102 fixedly connected to one side of the housing 101. A protective cover 103 is fixed to the inner wall of one end of the housing 101 by bolts. A servo motor 104 is fixedly installed on one side of the housing 101. The output end of the servo motor 104 passes through one side of the housing 101 and is fixedly connected to a sleeve 105. The sleeve 105 is rotatably connected to a plurality of fan blades 106.

[0049] The water spray unit 200 includes a water pipe 201 fixedly connected to one side of the housing 101, a sealing cylinder 202 is rotatably connected to the inner wall of the sleeve 105, the bottom end of the water pipe 201 passes through the housing 101 and is rotatably connected to one end of the sealing cylinder 202, a plurality of water outlet holes corresponding to each other are provided on the inner walls of the sleeve 105 and the sealing cylinder 202, a plurality of water spray heads 203 connected to the water outlet holes are fixedly connected to one side of the sleeve 105, a first limit plate 204 and a second limit plate 205 are fixedly connected to one side of the sealing cylinder 202, an arc-shaped slide groove fitting the first limit plate 204 and the second limit plate 205 is provided on one side of the sleeve 105, and a sewage pipe 206 is fixedly connected to the lower part of one side of the housing 101;

[0050] The foaming unit 300 includes a filling pipe 301 fixedly connected to one side of the casing 101, the bottom end of the filling pipe 301 passes through the casing 101 and is fixedly connected to a foam box 302, a piston rod 303 slides through the bottom of the inner cavity of the foam box 302, and a plurality of foam nozzles 305 are fixedly connected to the bottom of the foam box 302. The foaming unit 300 also includes a driving assembly 304 for driving the piston rod 303 to move.

[0051] Among them, the driving assembly 304 includes a gear 3041 fixedly sleeved on the sleeve 105, and the inner wall of the casing 101 is rotatably connected to a flywheel 3042 that meshes with the gear 3041, and one side of the flywheel 3042 is rotatably connected to a rotating rod 3043, and one end of the rotating rod 3043 is hinged to the bottom end of the piston rod 303 with a connecting plate 3044.

[0052] A plurality of air inlets are provided on one side of the protective cover 103 for taking air into the housing 101, and the air inside the housing 101 is discharged from the air outlet 102. When the servo motor 104 drives the sleeve 105 to rotate forward, the fan blades 106 are deflected toward the direction of the second limit plate 205 by centrifugal force, and the fan blades 106 push the second limit plate 205 to move along the arc-shaped slide groove of the sleeve 105. At this time, the fan blades 106 begin to deflect toward one end of the second limit plate 205, and the fan blades 106 are deflected toward one end of the second limit plate 205, and the fan blades 106 are deflected toward the second limit plate 205. The blade 106 is in an inclined state, so that the servo motor 104 drives the blade 106 to rotate to generate air volume, and at this time, the water outlet positions of the sleeve 105 and the sealing cylinder 202 are staggered. When the blade 106 needs to be cleaned, the servo motor 104 is rotated in a certain direction, and the gear 3041 drives the flywheel 3042 to rotate. The inside of the flywheel 3042 is a ratchet structure, and the tooth ring and the inner core ring of the flywheel 3042 can only rotate in one direction to rotate synchronously;

[0053] When the servo motor 104 rotates forward, the gear 3041 drives the toothed ring of the flywheel 3042 to rotate, while the inner core ring of the flywheel 3042 does not rotate. When the servo motor 104 rotates in the reverse direction, the toothed ring drives the inner core ring to rotate synchronously. The rotating rod 3043 is fixed on the inner core ring of the flywheel 3042. The rotating rod 3043 and the inner core ring are eccentrically arranged. The rotating rod 3043 drives the connecting plate 3044 to pull the piston rod 303 to move through the flywheel 3042. The top of the piston rod 303 performs a crank slider movement in the vertical direction in the inner cavity of the foam box 302. The top of the filling pipe 301 is arranged There is a sealing cover. Open the sealing cover and pour detergent, soapy water or other liquids that can dissolve oil and generate foam into the filling pipe 301, so that the detergent can flow into the inner cavity of the foam box 302. The bottom of the inner cavity of the foam box 302 is provided with a circular groove that fits the piston rod 303. When the piston rod 303 rises, the detergent flows into the circular groove, and the detergent is mixed with air through the piston rod 303 to generate a large amount of foam. Then the piston rod 303 descends and squeezes the detergent in the circular groove into the foam nozzle 305, and the foam nozzle 305 sprays the detergent into the inner cavity of the housing 101.

[0054] When the servo motor 104 rotates in the opposite direction, the fan blades 106 are deflected toward the first limit plate 204 by the action of centrifugal force, and then the fan blades 106 squeeze the first limit plate 204 and drive the sealing cylinder 202 to deflect so that the sleeve 105 and the water outlet hole of the sealing cylinder 202 overlap each other. At this time, the fan blades 106 and the central axis of the sleeve 105 are parallel, and the plurality of fan blades 106 are almost perpendicular to each other. At this time, the fan blades 106 will not introduce a large amount of external air into the housing 101, and the air will flow around the inner wall of the housing 101.

[0055] The cleaning agent sprayed by the foam nozzle 305 will be hit by the rotating fan blades 106 and generate more foam to dissolve the oil fume mixture on the fan blades 106 in all directions. After a certain period of reaction, the oil fume mixture is dissolved and falls off the fan blades 106. Then, the water pipe 201 is used to transport clean water into the sealing cylinder 202. The clean water in the sealing cylinder 202 passes through the water outlet holes of the sleeve 105 and the sealing cylinder 202 and flows to the water spray head 203. The multiple water spray heads 203 and the multiple fan blades 106 are arranged in a staggered distribution. The fan blades 106 can be washed by the water spray heads 203, and the fan blades 106 will shake off the oil fume mixture and the cleaning agent foam on their own surfaces under the action of centrifugal force to ensure that no pollutants remain on the surface of the fan blades 106 after washing. The sewage after washing is discharged through the sewage pipe 206.

[0056] Then the water pipe 201 stops supplying water and starts the servo motor 104 for forward rotation. At this time, the inner core ring of the flywheel 3042 will not drive the rotating rod 3043 to rotate, and the fan blades 106 are deflected again toward the direction of the second limit plate 205 by centrifugal force, and push the sleeve 105 to deflect, so that the positions of the water outlet holes of the sleeve 105 and the sealing cylinder 202 are staggered with each other. At this time, the water spray head 203 cannot spray water, and the fan blades 106 are tilted again, so that the fan blades 106 can introduce a large amount of external air into the casing 101, and dry the interior of the casing 101 to ensure that the fan is not only clean inside after cleaning, but also can be put into use quickly.

[0057] In addition, the shape of the water spray head 203 is Y-shaped, and both ends of the water spray head 203 are fixedly connected with a spherical sleeve 207. The surface of the spherical sleeve 207 is provided with a plurality of spray holes facing the fan blades 106. Both sides of the fan blades 106 are provided with a plurality of wave grooves 208 and a plurality of straight grooves. The plurality of wave grooves 208 located on one side of the fan blades 106 are connected by two straight grooves, and the wave grooves 208 and the straight grooves both have a smooth transition with the surface of the fan blades 106.

[0058] The two ends of the water spray head 203 are respectively inclined upward toward the direction of two adjacent fan blades 106, and the multiple spray holes of the spherical sleeve 207 are all oriented toward the fan blades 106, so that the spherical sleeve 207 can disperse the clean water sprayed by the water spray head 203 and expand the spraying range of the water spray head 203 to improve the effect of flushing the fan blades 106. When the detergent foam dissolves the oil smoke mixture on the surface of the fan blade 106, the wave groove 208 can increase the time that the detergent stays on the fan blade 106, so that the fan blade 106 can rotate. During the process, part of the detergent foam will be intercepted by the wave groove 208 and will not be directly thrown out on the surface of the fan blade 106. The detergent foam can flow into multiple wave grooves 208 in sequence through the straight grooves to improve the effect of the detergent foam on dissolving the oil fume substance. The connection between the wave groove 208 and the straight groove is provided with multiple smoothly transitioned fillets, and the opening of the wave groove 208 and the opening of the straight groove are both arc-shaped and smoothly transitioned to the surface of the fan blade 106, so that the oil fume mixture will not accumulate in the wave groove 208 and the straight groove.

[0059] Furthermore, a limit rod 306 is threadedly connected to one side of the housing 101, and the bottom end of the limit rod 306 passes through the top of the housing 101 and the foam box 302 in sequence. The top of the piston rod 303 is fixedly connected to a T-shaped plate 307, and a plurality of hourglass-shaped holes are opened on the top of the T-shaped plate 307.

[0060] The piston rod 303 drives the T-plate 307 to slide vertically along the inner wall of the foam box 302, so that the detergent continuously passes through the hourglass-shaped hole and continuously flows in and out from both ends of the hourglass-shaped hole. The detergent is fully stirred and mixed with the air through the T-plate 307 and the hourglass-shaped hole to generate a large amount of high-density foam, thereby improving the effect of dissolving the oil fume substance. When the fan blade 106 has finished cleaning, the limit rod 306 is rotated to make it contact with the T-plate 307, and the piston rod 303 is squeezed downward through the T-plate 307 to ensure that the top of the piston rod 303 can be located in the circular groove at the bottom of the inner cavity of the foam box 302, thereby preventing the detergent in the foam box 302 from directly flowing out through the foam nozzle 305, thereby causing waste.

[0061] Furthermore, it also includes an auxiliary unit 400, which includes a sealing disk 401 rotatably connected to one side of the protective cover 103, a handle 402 is fixedly connected to one side of the sealing disk 401, two limit columns 403 are fixedly connected to one side of the protective cover 103, and an arc plate 406 is fixedly connected to the inner wall of the casing 101, and the arc plate 406 is close to the upper side of the foam box 302, and a plurality of circular holes are opened on one side of the arc plate 406.

[0062] A plurality of air inlets corresponding to the protective cover 103 are provided on one side of the sealing disk 401. A handle 402 is provided to facilitate the user to rotate the sealing disk 401. The handle 402 is located between two limiting posts 403. The limiting posts 403 are used to limit the handle 402 so that the sealing disk 401 can be controlled in terms of its rotation angle. The limiting posts 403 located above one side of the protective cover 103 are used to align the sealing disk 401 and the protective cover 103 with each other so that the outside air can pass through the air inlets of the sealing disk 401 and the protective cover 103 and be delivered to the casing 101. The limiting posts 403 located below one side of the protective cover 103 are used to stagger the sealing disk 401 and the protective cover 103 so that the sealing disk 401 and the protective cover 103 are staggered with each other.

[0063] At this time, the air inlet of the protective cover 103 is completely covered by the sealing disk 401, so that during the cleaning of the fan blades 106, cleaning foam and sewage will not be discharged from the air inlet of the protective cover 103, so as to ensure that the fan blades 106 will not cause pollution to the external environment during the cleaning process. The arc plate 406 is used to intercept the water flow. When the fan blades 106 rotate in the casing 101, part of the foam and clean water will flow in a rotational manner along the inner wall of the casing 101. The arc plate 406 can block the foam and clean water attached to the inner wall of the casing 101 and divert them to the fan blades 106 for cleaning. At the same time, part of the foam and clean water can quickly pass through the through hole and be ejected out, so that part of the foam is impacted and split and quickly forms foam, so as to improve the effect of dissolving the oil fume mixture.

[0064] A method for cleaning a fan, the method for using the fan is applicable to any of the above fans, and the method for using the fan comprises the following steps:

[0065] Step 1: When cleaning the fan blade 106, the sealing disk 401 is rotated to cover the air inlet of the protective cover 103, and then the cleaning agent is added into the filling pipe 301, and the sleeve 105 is driven to rotate by the servo motor 104, so that the fan blade 106 pushes the first limit plate 204 by centrifugal force;

[0066] Step 2: The first limit plate 204 drives the sealing cylinder 202 to deflect, at which time the water outlet positions of the sleeve 105 and the sealing cylinder 202 overlap each other, and the flywheel 3042 drives the rotating rod 3043 to rotate through the gear 3041, and the rotating rod 3043 drives the piston rod 303 through the connecting plate 3044 to transport the detergent in the foam box 302 to the foam nozzle 305;

[0067] Step 3: The foam nozzle 305 sprays the detergent toward the rotating fan blade 106, so that the detergent generates a large amount of foam in the inner cavity of the housing 101, and the oil fume mixture attached to the surface of the fan blade 106 is dissolved by the detergent foam;

[0068] Step 4: The water pipe 201 is connected to an external water source, and clean water is delivered to the water spray head 203 through the water pipe 201. The spherical sleeve 207 is used to flush the surface of the fan blade 106, so that the oil smoke and foam on the surface of the fan blade 106 are washed away, and the sewage generated by the flushing is discharged through the sewage pipe 206;

[0069] Step 5: After the flushing is completed, the supply of clean water to the water pipe 201 is stopped, and then the sealing disk 401 is rotated to open the air inlet of the protective cover 103, and then the servo motor 104 drives the sleeve 105 to rotate in the opposite direction, and the fan blade 106 pushes the second limit plate 205 through the centrifugal force, so that the positions of the sleeve 105 and the water outlet hole of the sealing cylinder 202 are staggered, and the fan blade 106 returns to the inclined state;

[0070] Step 6: The piston rod 303 is used to seal the foam box 302 by rotating the limit rod 306 , and then the rotating fan blades 106 are used to suck the outside air into the housing 101 to air-dry the housing 101 .

[0071] Embodiment 2

[0072] Reference Figure 6 The difference from the first embodiment is that the inner wall of the housing 101 is rotatably connected with an adjusting rod 404 , a tooth plate 405 is threadedly sleeved on the adjusting rod 404 , and the tooth plate 405 is slidably arranged on the inner wall of the housing 101 .

[0073] By rotating the two bolts on one side of the protective cover 103, the protective cover 103 can be removed from the inner wall of the casing 101, and by rotating the adjusting rod 404, the tooth plate 405 can slide along the inner wall of the casing 101. When the teeth on the tooth plate 405 are engaged with the teeth of the flywheel 3042, the gear 3041 is also locked by the flywheel 3042, so that the sleeve 105 will not drive the fan blades 106 to rotate, so as to fix the position of the fan blades 106, and the user can manually perform secondary cleaning and maintenance on the fan blades 106 to ensure the cleanliness of the fan blades 106 and always maintain a good state for operation. By rotating the adjusting rod 404 in the opposite direction, the tooth plate 405 is no longer in contact with the flywheel 3042, and the protective cover 103 is reinstalled back into the casing 101, and then the fan blades 106 can be driven normally to rotate.
