Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0026] This embodiment provides a side suction range hood, the side suction range hood includes a box body and a panel 1, the air inlet of the box body is provided with a mesh plate 2, such as figure 1 and figure 2 As shown, the side suction range hood also includes a transmission mechanism 3 connected between the net plate 2 and the panel 1, the transmission mechanism 3 is connected with a driving mechanism, and the driving mechanism rotates in a direction to drive the The transmission mechanism 3 drives the panel 1 to reciprocate and periodically move linearly. Wherein, the driving mechanism is arranged in the box body.

[0027] In this embodiment, a transmission mechanism 3 is provi...

Abstract

The invention relates to a side suction type range hood. The invention belongs to the technical field of range hoods. The side suction type range hood comprises a box body and a panel; a screen plateis arranged at an air inlet of the box body; the side suction type range hood further comprises a transmission mechanism connected between the screen plate and the panel, the transmission mechanism isconnected with a driving mechanism, and the driving mechanism directionally rotates to drive the transmission mechanism to drive the panel to do reciprocating periodic linear movement. According to the invention, the transmission mechanism is arranged between the screen plate and the panel; the transmission mechanism can drive the panel to reciprocate periodically and linearly through one-way rotation of the driving mechanism so that lifting of the panel is achieved, the situation that in the ascending and descending process of the panel, due to frequent forward and reverse rotation of the driving mechanism, a return stroke gap is generated in the panel is avoided, the stroke starting position and the stroke ending position of the panel are accurately positioned, and meanwhile the servicelife of the driving mechanism is prolonged.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a side suction type range hood. Background technique [0002] At present, the automatic lifting of the side suction range hood panel generally adopts traditional methods such as electric push rod, gear, rack, chain drive and belt drive. [0003] Since the range hood mainly uses sheet metal parts as the main parts, the above-mentioned structure increases the difficulty of the range hood in terms of structural design, stability, and fine work; and the existing technical solutions use the motor to drive the operation of the entire mechanism. It is inevitable to make the motor frequently start in forward and reverse directions, and the frequent forward and reverse start of the motor greatly reduces the service life of the motor. The worm-worm mechanism, gear-rack mechanism and chain drive used in electric push rods also inevitably produce backlash, resulting in unstable automati...
