Moreover, before the sponge brush is stored in the storage shell, the scraper can be moved to scrape off the grease and dirt remaining on the surface of the sponge brush, so that the surface of the sponge brush is kept clean, thereby further ensuring the subsequent use effect of the sponge brush.

[0021] 2. The automatic water-washing fireproof and environmentally friendly oil fume exhaust hood described in the present invention adds cleaning water into the water tank and then starts the pump body. The pump body draws the cleaning water out of the water tank, passes through the hose and reaches the long tube, and then sprays it from the nozzle to automatically flush the inner cavity of the smoke hood. At the same time, under the action of motor 2, the long tube can be rotated within a certain range to change the angle of the nozzle, so that the cleaning water can be evenly sprayed to the inside of the smoke hood, thereby expanding the coverage of the cleaning liquid and improving the uniformity of flushing. Moreover, when only local stains need to be flushed, the angle of the nozzle can also be changed to ensure that the water flow is more concentrated and accurately covers the area that needs to be cleaned, thereby avoiding waste of water flow and being more environmentally friendly.

[0022] 3. The automatic water-washing fireproof and environmentally friendly oil fume exhaust hood described in the present invention has a fireproof effect on the smoke hood when the temperature sensor detects that the temperature around the smoke hood exceeds a preset safety threshold, and the alarm will sound to remind the surrounding personnel to cut off the corresponding power supply. In addition, when the alarm sounds, the pump body will pump out the water inside the water tank and use the nozzle to spray the water to extinguish the fire, thereby having a fireproof effect on the smoke hood and improving safety.

[0040] The inner cavity of the housing 18 is fixedly connected to the motor 5 31, and the output end of the motor 5 31 is fixedly connected to the middle of the front end of the mounting plate 2 30;

[0041] The left and right ends of the upper side of the mounting plate 2 30 are rotatably provided with a mounting plate 16, and the rear end surface of the mounting plate 16 is fixedly connected to the sponge brush 17;

[0042] A worm gear 20 is fixedly connected to one end of the mounting plate 16, and the worm gear 20 is rotatably mounted on the mounting plate 2 30. A fixing plate 19 is fixedly connected to the middle portion of the upper side of the front end surface of the mounting plate 2 30. Worms 29 are rotatably mounted on both the left and right sides of the fixing plate 19. A motor 3 21 is fixedly connected to the lower side of the right end surface of the fixing plate 19. The output end of the motor 3 21 is fixedly connected to the right end of the worm 29.

[0043] Threaded rods 24 are rotatably provided on both the left and right ends of the upper front end of the smoke collecting hood 1. The threaded rods 24 are threadedly connected to the scraper 23. The rear end of the scraper 23 is slidably connected to the limit rod 25. The left and right ends of the limit rod 25 are fixedly connected to the smoke collecting hood 1. The right end of the upper front end of the smoke collecting hood 1 is fixedly connected to the motor 4 22. The output end of the motor 4 22 is fixedly connected to the right end of the threaded rod 24.

[0044] Specifically, the range hood is a common appliance in the kitchen. During the cooking process, especially high-temperature cooking methods such as frying, deep-frying, and stir-frying, a large amount of oil smoke is generated. The range hood can effectively absorb the oil smoke and discharge it outdoors, thereby keeping the kitchen air fresh. When in use, the existing range hood can automatically flush the inner wall of the fume hood 1 to solve the problem of harm to the human body caused by the traditional manual spraying of oil dispersants, and improve the convenience and safety of cleaning the fume hood. However, for some more stubborn stains, it is inconvenient to completely remove the stains on the inner wall of the fume hood 1 and the flue 26 by flushing alone, thereby affecting the overall washing effect.

[0045] Therefore, in order to solve the above problem, when using the long tube 12 and the nozzle 13 to flush the inner wall of the smoke hood 1, the box door 8 can be opened, and the connecting rod 1 4 can be rotated under the action of the motor 1 3, so that the angle between the connecting rod 1 4 and the connecting rod 2 5 can be changed, so that the mounting plate 3 6 is moved out of the storage shell 2, and then the motor 7 33 is used to drive the connecting rod 3 7 to rotate, and the T-shaped plate 10 can be lowered with the cooperation of the connecting rod 4 9 until the lower surface of the sponge brush 17 is flush with the lower surface of the inner cavity of the smoke hood 1, and then the T-shaped plate 10 is driven to move horizontally again to make the sponge brush 17 close to the inside of the smoke hood 1, so that the lower surface of the sponge brush 17 and the lower surface of the inner cavity of the smoke hood 1 can form friction. The stains can be removed by friction, and the inner wall of the smoke hood 1 can be fully wiped by adjusting the horizontal and vertical positions of the sponge brush 17. When it is necessary to wipe the upper surface of the inner cavity of the smoke hood 1, the motor 6 32 can be used to drive the L-shaped rod 11 to rotate 90 degrees, so that the sponge brush 17 is turned over and the upper surface of the inner wall of the smoke hood 1 can be wiped. Since some stains may also adhere to the inner wall of the flue 26, after the L-shaped rod 11 is rotated 90 degrees, the motor 3 21 can be started to drive the worm 29 to rotate, so that the worm gears 20 and the mounting plate 1 16 on both sides rotate in different directions at the same time, so as to bend the sponge brush 17 downward and from the middle until the sponge brush 17 can be inserted into the flue 26 and both sides of the sponge brush 17 can contact the inner wall of the flue 26. Then, the motor 5 31 is used to drive the mounting plate 2 30 to rotate, so that the sponge brush 17 rotates, and the stains on the inner wall of the flue 26 are wiped, thereby avoiding the problem of poor oil smoke circulation caused by excessive oil stains adhering to the inner wall of the flue 26.

[0046] Since the sponge brush 17 absorbs cleaning water when in use, when the sponge brush 17 absorbs more cleaning water, its adsorption effect on stains will be affected. Therefore, after the sponge brush 17 has been wiping for a period of time, the motor 3 21 can be used to drive the worm 29 to rotate again, so that the sponge brush 17 is bent from the middle, and the left and right sides of the sponge brush 17 face each other and contact each other, so as to form an extrusion, squeeze out the water in the sponge brush 17, and ensure the subsequent adsorption effect. At the same time, the water in the sponge brush 17 can also be squeezed out after the scrubbing work is completed to avoid the sponge brush 17 being in a wet state for a long time, thereby breeding bacteria and mold, thereby ensuring the subsequent use effect of the sponge brush 17;

[0047] When the sponge brush 17 finishes the scrubbing work, a certain amount of grease will adhere to its surface. In order to prevent the residual grease from affecting the subsequent use of the sponge brush 17, the sponge brush 17 can be driven to rise and the lateral position of the sponge brush 17 can be adjusted to align and fit with the scraper 23. Moreover, when the sponge brush 17 rises and fits with the scraper 23, the scraper 23 can be used to scrape off the grease on the side of the sponge brush 17. Then, the motor 22 drives the threaded rod 24 to rotate, so that the scraper 23 moves laterally, and the scraper 23 fits with the rear end face and the upper and lower end faces of the sponge brush 17 to scrape off the grease on the surface of the sponge brush 17, thereby realizing the self-cleaning of the residual grease on the surface of the sponge brush 17, and further ensuring the subsequent use effect of the sponge brush 17. The sponge brush 17 after cleaning can be returned to the storage shell 2 for storage.

[0048] The self-cleaning auxiliary brushing mechanism can be used to wipe the inner wall of the smoke hood 1 with the sponge brush 17 while washing with water. The stubborn stains can be removed through friction, thereby improving the washing effect. Moreover, the shape of the sponge brush 17 can be changed so that it can be bent and extended into the flue 26 to wipe and clean the stains on the inner wall of the flue 26. Moreover, after the sponge brush 17 has been used for a period of time or after the work is completed, the sponge brush 17 can be driven to bend in the other direction to squeeze out the water adsorbed by the sponge brush 17, thereby ensuring the subsequent adsorption effect of the sponge brush 17 and avoiding the situation where the sponge brush 17 is in a wet state for a long time, thereby breeding bacteria and mold, thereby ensuring the subsequent use effect of the sponge brush 17. Moreover, before the sponge brush 17 is stored in the storage shell 2, the scraper 23 can be moved to scrape off the oil and dirt remaining on the surface of the sponge brush 17, so that the surface of the sponge brush 17 remains clean, further ensuring the subsequent use effect of the sponge brush 17.

[0049] In this embodiment, as shown in FIG7 , a temperature sensor 34 is provided on one side of the right end surface of the smoke collecting hood 1 , and an alarm 35 is provided on one side of the right end surface of the smoke collecting hood 1 , and the temperature sensor 34 is electrically connected to the alarm 35 ;

[0050] Specifically, when the temperature sensor 34 detects that the temperature around the smoke hood 1 exceeds a preset safety threshold, the alarm 35 will sound an alarm to remind surrounding personnel to cut off the corresponding power supply. In addition, when the alarm 35 sounds an alarm, the pump body 28 will pump out the water inside the water tank 27 and use the nozzle 13 to spray the water to extinguish the fire, thereby having a fire prevention effect on the smoke hood 1 and improving safety.

[0051] Working principle: Add cleaning water into the water tank 27, then start the pump body 28, the pump body 28 draws the cleaning water out of the water tank 27, reaches the long tube 12 after passing through the hose 15, and then sprays it out from the nozzle 13 to automatically flush the inner cavity of the smoke hood 1. At the same time, under the action of the motor 2 14, the long tube 12 can be rotated within a certain range to change the angle of the nozzle 13, so that the cleaning water can be evenly sprayed into the inside of the smoke hood 1, thereby expanding the coverage of the cleaning liquid and improving the uniformity of flushing. Moreover, when only local stains need to be flushed, the angle of the nozzle 13 can also be changed to ensure that the water flow is more concentrated and accurately covers the area that needs to be cleaned. This avoids waste of water flow and is more environmentally friendly. When the temperature sensor 34 detects that the temperature around the smoke hood 1 exceeds a preset safety threshold, the alarm 35 will sound an alarm to remind nearby personnel to cut off the corresponding power supply. In addition, when the alarm 35 sounds an alarm, the pump body 28 will pump out the water inside the water tank 27 and use the nozzle 13 to spray the water to extinguish the fire, thereby having a fire prevention effect on the smoke hood 1 and improving safety. When the long tube 12 and the nozzle 13 are used to flush the inner wall of the smoke hood 1, the box door 8 can be opened and the connecting rod 1 4 can be rotated under the action of the motor 1 3, so that the angle between the connecting rod 1 4 and the connecting rod 2 5 can be changed, so that the mounting plate 3 6 can be moved from the storage The shell 2 is moved out, and then the motor seven 33 is used to drive the connecting rod three 7 to rotate, and the T-shaped plate 10 can be lowered with the cooperation of the connecting rod four 9 until the lower surface of the sponge brush 17 is flush with the lower surface of the inner cavity of the smoke hood 1, and then the T-shaped plate 10 is driven to move horizontally again to make the sponge brush 17 close to the inside of the smoke hood 1, so that the lower surface of the sponge brush 17 and the lower surface of the inner cavity of the smoke hood 1 form friction, and the stains can be removed by friction, and the horizontal and vertical positions of the sponge brush 17 can be adjusted to fully wipe the inner wall of the smoke hood 1. When it is necessary to wipe the upper surface of the inner cavity of the smoke hood 1, the motor six 32 can be used to drive the L-shaped rod 11 to rotate ninety degrees, so that the sponge brush 17 can be turned over. The upper surface of the inner wall of the smoke hood 1 can be wiped by rotating the motor 3 21 , and since the inner wall of the flue 26 may also be adhered to some stains, when the L-shaped rod 11 is rotated 90 degrees, the worm 29 can be driven to rotate by starting the motor 3 21 , so that the worm gears 20 on both sides and the mounting plate 1 16 rotate in different directions at the same time, so as to move the sponge brush 17 downward and bend it from the middle until the sponge brush 17 can be inserted into the flue 26 and both sides of the sponge brush 17 can contact the inner wall of the flue 26 , and then the motor 5 31 is used to drive the mounting plate 2 30 to rotate, so that the sponge brush 17 rotates, and the stains on the inner wall of the flue 26 can be wiped, thereby avoiding the situation where too much oil and dirt adhere to the inner wall of the flue 26 and the smoke circulation is not smooth;Since the sponge brush 17 absorbs cleaning water when in use, when the sponge brush 17 absorbs more cleaning water, it will affect its adsorption effect on stains. Therefore, after the sponge brush 17 has been wiping for a period of time, the motor 3 21 can be used again to drive the worm 29 to rotate, so that the sponge brush 17 is bent from the middle, and the left and right sides of the sponge brush 17 face and contact each other, so as to form an extrusion, squeeze out the water in the sponge brush 17, and ensure the subsequent adsorption effect. At the same time, the water in the sponge brush 17 can also be squeezed out after the scrubbing work is completed to prevent the sponge brush 17 from being in a wet state for a long time, thereby breeding bacteria and mold. The situation of bacteria ensures the subsequent use effect of the sponge brush 17; when the sponge brush 17 completes the scrubbing work, a certain amount of grease will be attached to its surface. In order to avoid the influence of these residual grease on the subsequent use of the sponge brush 17, the sponge brush 17 can be driven to rise and the lateral position of the sponge brush 17 can be adjusted to align and fit with the scraper 23, and when the sponge brush 17 rises and fits with the scraper 23, the scraper 23 can be used to scrape off the grease on the side of the sponge brush 17, and then the motor 22 is used to drive the threaded rod 24 to rotate, so that the scraper 23 moves laterally, and the scraper 23 is aligned with the rear end surface of the sponge brush 17, The upper and lower end surfaces fit together to scrape off the grease on the surface of the sponge brush 17, thereby realizing the self-cleaning of the residual grease on the surface of the sponge brush 17, and further ensuring the subsequent use effect of the sponge brush 17; the sponge brush 17 after cleaning can be reset to the storage shell 2 for storage; thereby utilizing the self-cleaning auxiliary brushing mechanism, the sponge brush 17 can be used to wipe the inner wall of the smoke hood 1 while washing with water, and stubborn stains can be removed by friction, thereby improving the washing effect, and the shape of the sponge brush 17 can be changed to make it extend into the flue 26 in a bent manner to wipe and clean the stains on the inner wall of the flue 26. Moreover, after the sponge brush 17 has been used for a period of time or after work is completed, the sponge brush 17 can be bent in the other direction to squeeze out the water absorbed by the sponge brush 17, thereby ensuring the subsequent adsorption effect of the sponge brush 17 and preventing the sponge brush 17 from being wet for a long time, thereby breeding bacteria and mold, thereby ensuring the subsequent use effect of the sponge brush 17. In addition, before the sponge brush 17 is stored in the storage case 2, the scraper 23 can be moved to scrape off the oil and dirt remaining on the surface of the sponge brush 17, so that the surface of the sponge brush 17 remains clean, further ensuring the subsequent use effect of the sponge brush 17.
