The first bracket is arranged on one side of the bottom of the auxiliary sealing inner cover, and the plug-in frame is arranged on the other side of the bottom of the auxiliary sealing inner cover, and the plug-in frame is inserted into the back cover through the back side of the back cover. The auxiliary sealing inner cover is slidably plugged above the first bracket and the plug-in frame. The front side of the auxiliary sealing inner cover has the same curvature as the top plate and is interlocked with the top plate. The bottom of the auxiliary sealing inner cover contacts the back cover to one side, thereby sealing the space on the left and right sides of the inner cavity of the back cover, reducing the smoking space of the entire volute, which can increase the smoking efficiency while reducing the cleaning surface. The shockproof gasket is arranged in the space formed between the auxiliary sealing inner cover and the side wall of the back cover, the second bracket is arranged on the top of the shockproof gasket, and the first bracket and the second bracket are both arranged on the side wall of the back cover; by arranging the auxiliary sealing inner cover on the left and right sides of the volute corresponding to the front side of the inner wall of the back cover, the bottom of the auxiliary sealing inner cover is in contact with the top of the top plate, so that a small space for better absorption of the volute is formed by combining the two auxiliary sealing inner covers, the top plate and the back cover, so that the suction force of the volute is further increased, and at the same time, shockproof gaskets for absorbing the vibration of the auxiliary sealing inner cover are arranged above the two sides of the auxiliary sealing inner cover and the back cover, which are used for soft materials with lighter materials, which can reduce the counterweight and have a shock-absorbing effect.

[0035] The protective device includes a first fixed plate, a small motor, a rotating shaft, a rubber ring, a second fixed plate, a sealing seat and a protective cover. The protective cover is sleeved on the surface of the output end of the steel water pipe and protects multiple spray heads. The connection between the protective cover and the steel water pipe is connected through a bearing. A water spray port is provided at the protective cover corresponding to the spray head. The second fixed plate is sleeved on the surface of the steel water pipe. A sealing seat for sealing the water spray port is provided on the side of the second fixed plate facing the protective cover. The first fixed plate is arranged on the top of the second fixed plate.

The rotating shaft is arranged on the output end of the small motor. The rubber ring is sleeved on the surface of the rotating shaft. The rubber ring and the protective cover are rollingly connected with each other.

[0036] A steel water pipe is inserted through one side of the inner wall of the volute casing, and a plurality of spray heads are arranged at one end surface facing the inner wall of the volute casing. In conjunction with a small water pump connected to the end of the steel water pipe, the cleaning liquid can be sprayed onto the inner wall of the volute casing to achieve a cleaning effect. At the same time, a protective device is sleeved on the surface of the spray head. The protective device adopts a hollow cylindrical protective cover to protect the spray head. At the same time, a water spray port is opened to facilitate the spraying of the spray head. One end of the protective cover is rotatably connected to the steel water pipe through a bearing, and a rotating shaft connected to a small motor at the top and a rubber ring on the surface. The rotation of the rubber ring can drive the protective cover to rotate through the mutual fit between the rubber ring and the protective cover. When the water spray port of the protective cover rotates to the sealing seat on the rear side, the protective cover has a sealing effect, which can prevent external oil smoke from entering the protective cover, thereby providing good protection for the spray head, increasing the service life of the spray head, and having a better effect on the cleaning of the volute casing in the later stage.

[0037] Working principle: When the structure needs to be disassembled for cleaning, hold the bottom of the top plate with both hands and move it to the left to make the top installation slide out of the auxiliary slide groove on the back of the front panel, then remove the top plate and clean it first, and slide the coarse filter rack to the left and right sides respectively to make it out of the top and bottom slide rails for cleaning;

[0038] When the inner volute has been used for a long time, waste oil will accumulate inside. At this time, it is necessary to use a small water pump to extract cleaning liquid in the water tank and clean the inner wall surface of the volute through a steel water pipe and a spray head. The high-speed rotation of the volute can clean the waste oil accumulated on the surface. The surface of the spray head is protected by a protective cover to prevent the spray head from being blocked by waste oil. At this time, when the spray head needs to be opened, the small water pump is turned on and the small motor is turned on synchronously, which drives the rotating shaft on the surface to start rotating, so that the rubber ring on the surface of the rotating shaft drives the protective cover to start rotating, so that the water spray outlet on the surface of the protective cover rotates out of the range of the sealing seat to the side of the spray head, so that the mist cleaning liquid sprayed by the spray head can clean the inside of the volute. At the same time, when cleaning is not needed, the small motor is turned on again to make the water spray outlet of the protective cover rotate to the side of the sealing seat again to achieve the sealing of the protective cover.

[0039] At this time, the interior of the entire range hood is exposed. According to the oil condition of the internal secondary filter, you can pull out the secondary filter from the front for cleaning. Then hold the oil collecting bucket and take out the oil collecting bucket along the two slides on the side. After the oil collecting bucket is taken out, lift the collection tank upwards and clean the waste oil inside the collection tank. At the same time, it is also convenient to clean due to its small area. Then you can place plastic wrap or tin foil on the guide slope for easy cleaning, and press it with the pressing rack to make it fit better to the side of the oil collecting bucket. Finally, replenish the internal cleaning liquid according to the condition of the top water tank.

[0040] Finally, it should be pointed out that the above embodiments are only representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention should be considered to belong to the protection scope of the present invention.
