Range hood with smoke blocking screen capable of being automatically opened and closed

Abstract

The invention discloses a range hood with a smoke blocking screen capable of being automatically opened and closed. The range hood comprises a box body and a fan system arranged in the box body, wherein the box body comprises a panel right aligned with a cooking bench, and an air inlet is arranged on the panel. The range hood is characterized in that the smoke blocking screen in size matching with the air inlet is hinged with the upper end of the air inlet through a rotating hinge, the inner side of the panel is provided with an electric push rod driven by a motor, the extending-out part of the electric push rod is connected with the rotating hinge, and the extending-out part can do linear movement for driving the rotating hinge to rotate so that the smoke blocking screen is opened or closed. The smoke blocking screen is hinged at the upper end of the air inlet of the panel through the rotating hinge, and the electric push rod drives the rotating hinge to rotate so that the smoke blocking screen rotates to be opened or closed, and a user cannot directly face the electric push rod for driving the smoke blocking screen when operating in front of the cooking bench, so the hidden opening and closing of the smoke blocking screen is realized; and in addition, the range hood is also provided a sudden stop prevention mechanism and a position limiting pin, wherein the sudden stop prevention mechanism can prevent the hand clamping of a user caused by the sudden stop, and the position limiting pin prevents the stroke exceeding of the smoke clocking screen and realizes the position limiting effect.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood with a smoke screen which can be opened and closed automatically. Background technique [0002] The existing near-suction range hood usually includes a casing, a fan system arranged in the casing, and a control switch. The casing includes side panels on both sides and a panel on the side facing the stove. The panel is provided with a suction port. After the power supply of the fan system is turned on, the oil fume is sucked into the fan system by the suction port and discharged to the public flue. This range hood is inconvenient to clean. In addition to cleaning the shell, it is also necessary to extend into the air suction port to clean the fan blades of the fan system in the shell or the partition net positioned at the air suction port. [0003] For this reason, improvements have been made on this basis, such as the Chinese patent with the authorized announcement number CN201628292...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned range hoods with flip cover do not need to open the flip cover when there is little oil fume; when the flip cover needs to be used, the motor drives the flip cover to open or close. You can directly see the support rods (or support frames, etc.) supported on both sides of the flip cover, which affects the user experience; after the long-term use of the motor, the stroke will become longer, which will cause the flip cover to close too far; and there is no anti-pinch function, when the flip cover is about to close , if the user operates the flip cover, there is a risk of injury
