The invention relates to the technical field of kitchen appliances, in particular to a range hood and a device with the range hood. The range hood comprises a cooking fume collection cover and an angle adjustment structure, wherein the cooking fume collection cover is arranged on an object for the range hood to be installed on, one end of the angle adjustment structure is rotationally connected with the object for the range hood to be installed on, and the other end of the angle adjustment structure is rotationally connected with the cooking fume collection cover. Because the angle adjustmentstructure is arranged, one end of the angle adjustment structure is rotationally connected with the object for the range hood to be installed on, and the other end of the angle adjustment structure isrotationally connected with the cooking fume collection cover, a user can adjust the angle and the position of the cooking fume collection cover according to the actual requirements, and for example,the user can adjust the height of the cooking fume collection cover by turning the cooking fume collection cover relative to the object for the range hood to be installed on, so that the cooking fumecollection cover adapts to the height of the user, and cooking fume is prevented from blowing to the user directly; and meanwhile, the user can further turn the cooking fume collection cover to carryout adjustment so that a cooking fume inlet of the cooking fume collection cover can be opposite to a kitchen range, then more cooking fume can be sucked in by the cooking fume collection cover, andthe cooking fume collection effect of the range hood is improved.

The invention discloses a novel automatic rising-falling extractor hood which comprises a machine shell, a wind chamber, a motor box, a threaded soft pipe, a fixing box, a fixing rod, a rack, a driving box and a rotating motor. The machine shell is internally provided with the wind chamber and the motor box from left to right, the upper end of the wind chamber communicates with a smoke vent, the smoke vent vertically and upwards extends to penetrate the upper end of the machine shell to communicate with the threaded soft pipe, the fixing box is arranged on the right side of the machine shell,the fixing rod is arranged on the right side of the fixing box, the rack is arranged on the right side of the fixing rod, the driving box is arranged on the right portion of the rack, a driving gear,a fixed gear and a driven gear which are meshed with each other are arranged in the driving box, and the left portion of the driven gear penetrates the driving box to be meshed with the rack. The novel automatic rising-falling extractor hood is obvious in lampblack sucking effect, rising and falling of the extractor hood are continuously adjusted according to the actual condition, when the lampblack amount is too large, the lampblack is blocked, sucked and removed in time through automatic rising and falling, the lampblack gathering effect is effectively improved, meanwhile, the user experience effect is improved, and the wide market prospect is achieved.

The invention discloses an air energy firewood stove. A firewood inlet is formed in an outer sleeve; a fire door is movably mounted at the firewood inlet; an inner firewood inlet corresponding to the firewood inlet is formed in an inner sleeve; a smoke collecting hole is formed between the outer sleeve and the inner sleeve on two side parts of the inner firewood inlet; a heating hole is formed in the stove surface; a cover plate is movably covered at the heating hole; an ash falling hole is formed in the bottom of the stove; furnace teeth are arranged in the ash falling hole; an ash chamber shell is arranged under the bottom of the stove; an ash hole is formed in the side part of the ash chamber shell; an ash hopper is inserted and mounted in the ash chamber shell through the ash hole; and a smoke exhaust hole is also formed in the outer sleeve. The air energy firewood stove has the advantages that the smoke is effectively prevented from directly dissipating out of the heating hole or the firewood inlet, so that the heat energy utilization rate is increased, the smoke collection effect is enhanced, the consumption of fuel is reduced, and the energy conservation and environment protection effects are improved.

The invention discloses a range hood having a fume collecting chamber and including: a frame; a second fume collecting plate having the rear side connected to the frame in lifting manner, one end of the second fume collecting plate is slidably connected with the frame in a preset path such that the second fume collecting plate may lower and turn to a preset position below the fume collecting chamber. The range hood herein has effectively improved applicability.

The present invention provides a range hood and a casing assembly thereof. The present invention provides a casing assembly of a range hood, comprising: a casing and a smoke inlet; the smoke inlet includes an air inlet and a deflector ; the smoke inlet is set to be suitable for switching between the first position and the second position; when the smoke inlet is switched from the first position to the second position, the smoke inlet at least extending partially from the casing; the deflector is arranged to be suitable for switching between a third position and a fourth position; when the deflector is in the third position, the deflector The air inlet is closed by the air flow plate; when the air guiding plate is in the fourth position, the air inlet is opened, and the air guiding plate is suitable for guiding the air flow into the air inlet. The range hood includes the cabinet assembly. The present invention reduces the volume while solving the bump problem.
