Side draught type extractor hood

Abstract

The invention discloses a side draught type extractor hood. The side draught type extractor hood includes a machine shell. The right front of the machine shell is provided with an air inlet. A smoke deflector is arranged in the air inlet. The machine shell is internally provided with an electric pushing rod mechanism used for driving the smoke deflector to overturn. The electric pushing rod mechanism includes a pushing rod outer shell and a pushing rod carrying out linear reciprocating motion relative to the pushing rod outer shell. The side draught type extractor hood is characterized in thatthe end, away from the pushing rod outer shell, of the pushing rod is connected with the smoke deflector through a first bearing. The end, away from the pushing rod, of the pushing rod outer shell isconnected with the machine shell through a second bearing. Through arranging the electric pushing rod mechanism into a double-bearing structure, the pushing rod can rotate around the bearing center,the pushing rod can be inclined to compensate disadvantages of low accuracy, when the centers of a rod end knuckle bearing and a mounted bearing are in misregistration, the straightness accuracy of the pushing rod can be ensured through a rotation shaft of the rod end knuckle bearing, and the radial force inside when the pushing rod moves can be eliminated.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a side suction type range hood with an electric push rod mechanism. Background technique [0002] Existing side suction range hoods usually include 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, as the Chinese patent application number 201020026644.5, which discloses a range ...

AI Technical Summary

Problems solved by technology

The above-mentioned installation method has the following disadvantages: 1. The range hood has been in the oil fume environment for a long time, and the common shaft and hole are connected. Use will reduce the service life of the push rod; 2. The gap between the shaft and the hole will cause the stop and shake when the smoke baffle is opened and closed due to the gap when the smoke baffle is moving and the direction of the smoke baffle is changed due to the force. Phenomenon; 3. The range hood box is made of sheet metal, and its assembly process is basically manual assembly on the assembly line. The assembly process is long and the precision is low. Due to the assembly error of the push rod, there will be a certain angle between the push rod and the push rod shell , Figure 12 As shown in , a certain angle is formed between the axis X of the push rod and the thrust F1 it receives, so that the push rod is bent by the radial force F2, which affects the operating efficiency and service life of the push rod, and at the same time causes the acceleration of the worm gear accelerated wear
