[0034] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0035] First embodiment:

[0036] See also Figure 1-Figure 9 The smoke collecting hood includes a main body 1, a raised portion 11 is provided at the upper front section of the main body 1, a lighting device 2 is provided at the lower side of the raised portion 11, a front plate is provided at the front side of the raised portion 11, an air inlet 111 is provided on the front plate, and an exhaust mechanism (not shown) connected to the air inlet 111 is provided in the main body 1. By setting the air inlet 111 at the front plate position of the raised portion 11, the oil smoke can relatively bypass the lighting device 2 in the process of entering the air inlet 111, thereby improving the lighting effect. At the same time, the air inlet 111 can better utilize the spatial position of the raised portion 11 to relatively increase the air intake, so that the oil smoke extraction effect is better.

[0037] Furthermore, the lighting device 2 on the lower side of the raised portion 11 is tilted upward from the rear side to the front side, which can increase the illumination range of the lighting device 2 and further improve the lighting effect compared to the method of horizontally arranging the lighting device 2.

[0038] Furthermore, the front plate of the raised portion 11 is tilted downward from the rear side to the front side, which can relatively increase the surface area of ​​the air inlet 111, thereby further improving the fume extraction effect.

[0039] Furthermore, the front plate of the raised portion 11 is connected to a movable cover 3, and the movable cover 3 is connected to a transmission mechanism. The movable cover 3 can open or close the air inlet 111 through the transmission mechanism. The user can control the movable cover 3 to open or close the air inlet 111 through the transmission mechanism as needed, thereby reducing the speed of dust accumulation inside the main body 1. At the same time, closing the air inlet 111 by the movable cover 3 can also make the smoke hood more beautiful as a whole.

[0040] Furthermore, the front plate of the raised portion 11 is connected to a single movable cover 3 , the width of the movable cover 3 is equivalent to the width of the front plate of the raised portion 11 , and the movable cover 3 in this embodiment is a single continuous plate shape that can continuously cover the front plate of the raised portion 11 .

[0041] Furthermore, the movable cover 3 opens or closes the air inlet 111 by flipping in the up and down direction relative to the front plate of the protrusion 11. The movable cover 3 can open the air inlet 111 and form a guide cavity 31 between the movable cover 3 and the front plate of the protrusion 11. The cross-sectional width of the guide cavity 31 decreases from bottom to top. The movable cover 3 can also guide the airflow so that the oil smoke can enter the air inlet 111 in a more concentrated manner.

[0042] Furthermore, the transmission mechanism includes a first hinge arm 41, a second hinge arm 42, a third hinge arm 43 and a driving assembly. The head end of the first hinge arm 41 is transmission connected to the driving assembly, the end of the first hinge arm 41 is hinged to the head end of the second hinge arm 42 through a first hinge shaft 441, the end of the second hinge arm 42 is hinged to the middle section of the third hinge arm 43 through a second hinge shaft 442, the third hinge arm 43 is C-shaped, the head end of the third hinge arm 43 is hinged to the main body 1 through a third hinge shaft 443, and the end of the third hinge arm 43 is fixedly connected to the movable cover 3.

[0043] The driving assembly can drive the end of the first hinge arm 41 and the head end of the second hinge arm 42 to swing around the head end of the first hinge arm 41. The head end of the second hinge arm 42 swinging around the head end of the first hinge arm 41 can drive the third hinge arm 43 to swing around its head end to make the movable cover 3 open or close the air inlet 111.

[0044] Compared with the method of directly driving the third hinge arm 43 to control the movable cover 3, adding the first hinge arm 41 and the second hinge arm 42 can relatively increase the force arm acting on the third hinge arm 43, thereby relatively reducing the power required to be provided by the drive assembly, and the power of the drive assembly can be relatively reduced. Moreover, compared with the method of using a cylinder drive, since the first hinge arm 41 and the second hinge arm 42 can be folded and stored with each other, the space occupied by the whole is relatively small, and the space position in the main body 1 can be more reasonably utilized to realize the driving of the third hinge arm 43, saving the space position inside the main body 1.

[0045] Furthermore, an oil retaining shell 5 is provided on the outer side of the driving component, and the oil retaining shell 5 can reduce the chance of the driving component contacting with oil smoke, thereby protecting the driving component.

[0046] The oil-blocking shell 5 is formed by processing of metal material. When the oil smoke contacts the oil-blocking shell 5 , it can condense to form oil stains more quickly and drip downwards, thereby reducing the chance of oil stains accumulating on the surface of the oil-blocking shell 5 .

[0047] The oil retaining shell 5 is detachably connected to the main body 1, so that the user can disassemble and clean it conveniently.

[0048] Furthermore, the driving assembly includes a motor 6 and a reduction gearbox 7, the motor 6 is transmission-connected to the reduction gearbox 7, the output end of the reduction gearbox 7 is transmission-connected to the head end of the first hinge arm 41, the reduction gearbox 7 can increase the output torque of the motor 6, and at the same time, can control the movable cover 3 to open or close the air inlet 111 at a relatively low speed.

[0049] Furthermore, the first hinge axis 441, the second hinge axis 442 and the third hinge axis 443 are all arranged in the horizontal direction, and the central axis of the motor 6 is arranged in the vertical direction, which can further utilize the vertical space position in the main body 1 for click installation, thereby improving the space utilization efficiency in the main body 1.

[0050] The horizontal height of the driving component corresponds to the upper position of the air inlet 111, which can relatively reduce the chance of the driving component coming into contact with oil smoke.

[0051] Furthermore, a maintenance window 12 is provided on the rear side of the main body 1 at a position corresponding to the transmission mechanism, and the maintenance window 12 is connected to a rear baffle 8 . The rear baffle 8 is detachably connected to the main body 1 , and the user can inspect and maintain the transmission mechanism by removing the rear baffle 8 .

[0052] Furthermore, a side panel is provided on the left and / or right side of the main body 1, and the transmission mechanism is arranged on the side of the side panel facing the inner side of the main body 1. The side panel is in the shape of a thin plate, which can relatively increase the spatial position inside the main body 1, facilitate the installation layout of components, and save materials.

[0053] Second embodiment:

The two movable covers 3 can be opened separately or all opened according to the needs of use.

[0055] The remaining undescribed parts are the same as those of the first embodiment and will not be repeated here.

[0056] Third embodiment:

[0057] The difference between this embodiment and the first embodiment is that the inner side of the side panel of the smoke hood has an assembly cavity for installing the transmission mechanism, and the transmission mechanism is arranged in the assembly cavity. The side panel of this embodiment is relatively thick, and there can be sufficient space in the assembly cavity to install the transmission mechanism. This method can further avoid the influence of oil smoke on the transmission mechanism and eliminate the phenomenon of the transmission mechanism being stuck due to oil smoke.
