Description

Technical Field

[0001] The utility model relates to the technical field of combustion-supporting fans, in particular to a combustion-supporting fan capable of adjusting air intake volume. Background Art

[0002] During the material combustion process, the fan can be used to blow air to the burning material, thereby improving the combustion efficiency of the material. Although the existing combustion-supporting fan can play the role of supporting the combustion of the material, it does not have the function of adjusting the wind force.

[0003] For example, when blowing air over materials, excessive wind force can extinguish the combustion of the materials, while weak wind force cannot achieve the combustion-supporting effect. Some fuels require gentle and scattered air, while others require concentrated air at one point. The combustion-supporting fans in the existing technology are not easy to adjust. The air intake of the combustion-supporting fans cannot be adjusted according to people's work needs and the degree of material combustion. The air volume and wind concentration point cannot be selected by the user, which easily affects the combustion of the materials, thereby increasing people's work pressure, failing to meet people's work needs, and reducing the working efficiency of the combustion-supporting fans. Utility Model Content

[0004] The purpose of this application is to provide a combustion-supporting blower with adjustable air intake volume, aiming to solve the problems in the prior art.

[0005] The embodiment of the present application provides a combustion-supporting fan with adjustable air intake volume, comprising a base plate; an adjusting base and a combustion-supporting fan are installed on the base plate; the combustion-supporting fan comprises a driving motor, a fan main body and an air supply cylinder; the air supply cylinder is provided with an air volume regulator; the air volume regulator consists of a wind reduction rotor and an air dispersion rotor; the internal structures of the wind reduction rotor and the air dispersion rotor both include an adjusting ring, a rotating cylinder and blades; the blades of the wind reduction rotor are sealing blades; the blades of the air dispersion rotor are perforated blades; the adjusting ring is fixedly arranged on the inner wall of the air supply cylinder; the adjusting ring is provided with a plurality of rotating blades; a first connecting rod and a second connecting rod are respectively provided at both ends of the bottom of the blade; the blades are rotatably connected to the adjusting ring through the first connecting rod; the second connecting rod is fixedly connected to the transmission rod; the other end of the transmission rod is fixedly arranged on the rotating cylinder; the rotating cylinder is rotatably connected to the outer wall of the air supply cylinder; there is an adjustment space between the rotating cylinder and the adjusting ring; a blade channel is provided on the wall of the air supply cylinder; the blade channel is connected to the adjustment space.

[0006] Furthermore, the adjustment base is rotatably arranged on the bottom plate; a group of symmetrical damping shafts are provided on the adjustment base; and the damping shafts are rotatably connected to the driving motor housing.

[0007] Furthermore, a rotating gear is provided at the bottom of the adjustment base; the rotating gear and the adjustment screw are engaged with each other; the adjustment gear is located inside the base plate, and the adjustment screw extends out of the base plate.

[0008] Furthermore, the rotating cylinders of the wind reduction rotating cylinder and the wind dispersion rotating cylinder are both provided with control handles.

[0009] Furthermore, the perforated blades are provided with evenly distributed holes.

[0010] Furthermore, the base plate is installed on a lift.

[0011] The beneficial effects of the present invention are as follows: the present invention designs two wind control devices. When the wind reduction drum is rotated, the air volume gradually decreases, and the blowing points are mainly concentrated at the center point; when the wind dispersion drum is rotated, the degree of wind force reduction is slower than that of the wind reduction drum, and the wind force points are scattered under the action of the blade holes, making the air volume gentle and dispersed. Users can switch to different drums according to the different materials and combustion degrees. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

A blade channel is provided on the wall of the air supply cylinder; the blade channel is connected to the adjustment space, and the blades can rotate along the blade channel into the adjustment space under the action of the transmission rod 604.

[0021] When the wind reducing drum 61 is rotated, the internal channel of the air supply drum 5 is reduced as the sealing blades shrink, so that the air volume gradually decreases, and the blowing points are mainly concentrated at the center point; when the wind dispersing drum 62 is rotated, due to the holes on the blades, the degree of wind reduction is slower than that of the wind reducing drum, and the wind points are scattered under the action of the blade holes, making the air volume gentle and dispersed.
