The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

As shown in fig. 1, the range hood of an embodiment includes a housing 1, a fan 2 and a dust suction mechanism 3, the housing 1 is provided with an oil smoke suction port 11 and an air outlet 12, a cavity (not shown) is provided in the housing 1, the cavity is communicated with the air outlet 12, the cavity is selectively communicated with the oil smoke suction port 11, the fan 2 is provided in the cavity, the dust suction mechanism 3 includes a flexible hose 31 and a dust removal assembly 32, the dust removal assembly 32 is provided on the housing 1, one end of the dust removal assembly 32 is selectively communicated with the cavity, and the other end of the dust removal assembly 32 is connected with the flexible hose 31.

When the garbage suction function is used, the smoke suction port 11 is closed, the dust suction mechanism 3 is communicated with the cavity, and then the fan 2 is started, so that the telescopic hose 31 has elasticity, and the garbage can be sucked into the dust removal assembly 32 without entering the cavity by stretching the telescopic hose 31 to the position where the garbage is located. When the conventional oil smoke suction work is required, the dust removal assembly 32 is not communicated with the cavity, and then the oil smoke suction port 11 is opened and the fan 2 is started. The range hood of this embodiment still possesses the function of removing to the absorption of rubbish on the kitchen mesa when possessing conventional range hood function, and is with low costs and convenient to use.

As shown in fig. 1, 2 and 4, further, the dust removing assembly 32 includes a cyclone dust cup 321, an air inlet pipe 322, an air outlet pipe 323 and an electromagnetic valve 324, wherein one end of the air inlet pipe 322 is connected to the flexible hose 31, the other end of the air inlet pipe 322 is tangent to the wall of the cyclone dust cup 321 and is communicated with the inside of the cyclone dust cup 321, one end of the air outlet pipe 323 is connected to the top surface of the cyclone dust cup 321 and is communicated with the inside of the cyclone dust cup 321, and the electromagnetic valve 324 is disposed at the other end of the air outlet pipe 323 and is located in the cavity. The electromagnetic valve 324 can realize selective communication between the air outlet pipe 323 and the cavity in the housing 1, and as the air inlet pipe 322 is tangent to the wall of the cyclone dust cup 321, kitchen garbage such as vegetable debris, salt particles, starch and the like and air are sucked into the cyclone dust cup 321 and then rotate around the inner wall of the cyclone dust cup 321, and due to the centrifugal force, the garbage can adhere to the inner wall of the cyclone dust cup 321 and finally deposit at the bottom of the cyclone dust cup 321 under the action of gravity, and lighter air enters the cavity in the housing 1 from the air outlet pipe 323, so that the separation of the garbage and the air is realized, and the damage to the fan 2 caused by the garbage entering the fan 2 is avoided.

As shown in fig. 3 and 4, the dust removing assembly 32 further includes a filter 325, and the filter 325 is disposed at an end of the air outlet pipe 323 away from the solenoid valve 324. When more garbage is accumulated in the cyclone dust separating cup 321, the garbage is possibly sucked into the air outlet pipe 323, and the filtering member 325 is arranged at one end of the air outlet pipe 323 far away from the electromagnetic valve 324, so that the situation can be effectively avoided.

In the illustrated embodiment, the filter element 325 is conical, the bottom surface of the filter element 325 is connected to the end surface of the air outlet pipe 323 away from the electromagnetic valve 324, and the side surface of the filter element 325 is provided with a plurality of filter holes 3251. If the filter element 325 is configured in a generally planar shape, the smaller surface area results in a smaller total area of the filter holes 3251, which in turn results in a greater resistance to the air flow and a reduction in the suction force.

As shown in fig. 3 and 4, further, the cyclone dust separating cup 321 includes an upper cup 3211 and a lower cup 3212, the upper cup 3211 is detachably connected to the lower cup 3212, and the air inlet pipe 322 and the air outlet pipe 323 are both disposed on the upper cup 3211. When the amount of garbage in the cyclone dust cup 321 is large, the garbage needs to be cleaned in time to ensure the normal operation of the dust removing assembly 32. If dismantle whole dust removal subassembly 32, waste time and energy, consequently leave the structure that dirt cup 321 design can separate from top to bottom with whirlwind to dismantle the lower cup 3212 with splendid attire rubbish alone, after rubbish is emptyd out, again with lower cup 3212 install again on last cup 3211 can, convenient laborsaving.

Further, go up cup 3211 and cup 3212 threaded connection down, go up cup 3211 and be equipped with the assorted screw thread on the cup 3212 down, good gas tightness and easy dismounting can be guaranteed to threaded connection's form.

As shown in fig. 1, 5 and 6, the range hood further comprises an electric push rod 4 and a blocking piece 5, the electric push rod 4 is arranged in the cavity, the blocking piece 5 is connected with the electric push rod 4, and the electric push rod 4 can stretch and retract so as to drive the blocking piece 5 to move, so that the blocking piece 5 can selectively block the oil smoke suction port 11. Of course, the form of the driving mechanism is not limited to the electric push rod 4, and other forms of driving mechanism may be adopted to drive the plugging member 5 to move.

The number of the electric push rods 4 is preferably two, the electric push rods 4 are arranged on the inner wall of the shell 1, and the two electric push rods 4 are respectively connected with two ends of the blocking piece 5, so that the blocking piece 5 can stably move up and down, and the oil smoke suction port 11 can be better sealed.

Further, the oil smoke suction port 11 is rectangular, the plugging piece 5 is quadrangular, the section of the plugging piece 5 is trapezoidal, the electric push rod 4 is connected with the top surface of the plugging piece 5, the length of the bottom surface of the plugging piece 5 is equal to that of the oil smoke suction port 11, and the width of the bottom surface of the plugging piece 5 is larger than that of the oil smoke suction port 11. The width of shutoff piece 5 is from last to increasing gradually down, and shutoff piece 5 need not enter into the cavity inside of casing 1 completely can seal oil absorption mouth 11, and when oil absorption mouth 11 closed completely, can keep certain pressure between the surface of shutoff piece 5 and the casing 1 to eliminate the gap between the two as far as possible, play better closed effect.

As shown in fig. 1, the range hood further comprises an oil collecting tank 6, wherein the oil collecting tank 6 is arranged right below the blocking piece 5 and connected with the bottom surface of the blocking piece 5. The oil smoke condensed on the range hood can flow into the oil collecting tank 6 under the action of gravity, so that the oil stain is prevented from dropping on the kitchen table to cause pollution.

In the detailed description of the embodiments, various technical features may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
