Aiming at the problems that the cleaning of the inner mesh cover at the volute of the fan of the existing range hood needs to be additionally provided with a driving piece, so that the manufacturing cost and the assembly cost are increased, and the whole volume of the range hood is increased, the invention provides the structure to realize the automatic cleaning of the inner mesh cover of the range hood, so as to avoid the reduction of the smoking effect, and simultaneously prevent the inner mesh cover from being blocked to cause mildewing and generate peculiar smell, and in addition, the structure can also reduce the manufacturing cost and the assembly cost of the range hood, and reduce the whole volume of the range hood. The specific structure is illustrated by the following examples.

Example one

The embodiment provides a range hood, as shown in fig. 1, the range hood includes a range hood housing 1, a smoke baffle 2, a fan 3, a transmission assembly 4 and a cleaning assembly 5, wherein the range hood housing 1 is provided with a smoke inlet, and smoke can enter through the smoke inlet and is sucked to the outside by the fan 3. The smoke baffle 2 is arranged on one side of the cigarette machine shell 1 (namely the range hood is a side-suction type cigarette machine) and can rotate relative to the cigarette machine shell 1 to open or close the smoke inlet. Fan 3, drive assembly 4 and clean subassembly 5 are all arranged in cigarette machine casing 1, mesh enclosure 31 in air intake department of fan 3 is provided with, 4 both ends of drive assembly are connected respectively and are kept off cigarette board 2 and clean subassembly 5, when keeping off cigarette board 2 and open or close for cigarette machine casing 1, drive assembly 4 and the linkage of keeping off cigarette board 2, it can drive the motion of drive assembly 4 to keep off cigarette board 2, drive assembly 4 then can drive clean subassembly 5 and remove for interior mesh enclosure 31, and then clean inner mesh enclosure 31.

In this embodiment, the smoke baffle 2 is driven by a driving member disposed on the casing 1 of the cigarette machine, and the driving member may be a motor, an electric push rod, or other driving components.

In this embodiment, can drive transmission assembly 4 when keeping off cigarette board 2 and rotate for cigarette machine casing 1, drive assembly 4 pivoted and drive clean subassembly 5 simultaneously and clean inner mesh cover 31. Illustratively, as shown in figure 2, a mount 11 may be provided on the cigarette machine housing 1, with the drive assembly 4 rotatably disposed on the mount 11.

Referring to fig. 2-4, the transmission assembly 4 includes a first connecting member 41, wherein the first connecting member 41 is bent, and the bent position is rotatably connected to the mounting base 11, a first end of the first connecting member 41 is slidably connected to the smoke baffle 2, and a second end of the first connecting member 41 can drive the cleaning assembly 5 to move. When keeping off the cigarette board 2 and rotating, the first end of first connecting piece 41 can be driven by keeping off the cigarette board 2 and remove to the cigarette machine casing 1 outside or inboard, because first connecting piece 41 rotates to be connected in mount pad 11, first connecting piece 41 can turn into for the rotation of mount pad 11 to the cigarette machine casing 1 outside or inboard removal this moment, first connecting piece 41 can drive clean subassembly 5 and rotate in order to clean interior screen panel 31, the first end of first connecting piece 41 slides along keeping off the cigarette board 2 simultaneously, can avoid first connecting piece 41 to appear rotating the dead angle, lead to the unable removal of clean subassembly 5, can not clean interior screen panel 31. In this embodiment, the shape of the inner mesh enclosure 31 is adapted to the rotation track of the cleaning assembly 5, so that the cleaning assembly 5 can contact and clean the inner mesh enclosure 31 when rotating.

As shown in fig. 4, in the present embodiment, a sliding slot 21 may be disposed on one side of the smoke barrier 2, and the first end of the first connecting member 41 can slide along the sliding slot 21. Illustratively, the third connecting member 22 may be provided on the smoke barrier 2, and optionally, the third connecting member 22 is fixed on the smoke barrier 2 by screws or rivets.
