Abstract

The invention relates to indoor ventilation equipment, in particular to indoor ventilation equipment capable of controlling ventilation quantity. The indoor ventilation equipment comprises an air duct, an inner channel of the air duct is circular, a plurality of inlets are formed below the air duct, baffles are arranged on the inlets, bottom covers are arranged in the inlets, straight rods are arranged above the bottom covers, electric push rods are arranged above the straight rods, the electric push rods are fixed in the air duct, movable shafts of the electric push rods are fixedly connected with the straight rods, through holes are formed in round balls, and rotating shafts are arranged on the upper portions and the lower portions of the round balls; and the multiple balls are located behind the multiple inlets, and transmission structures are connected with the rotating shafts and the bottom covers and used for driving the multiple balls to rotate. According to the indoor ventilation equipment, the opening states of the multiple inlets are controlled through the arranged electric push rods, specifically, the multiple inlets are sequentially opened along with the increase of the rotating speed of a fan, and the inlets in different positions have different effective ventilation ranges, so that the indoor ventilation efficiency is improved on the whole, and meanwhile, the problem that the ventilation effect is poor due to the fact that a ventilation pipeline is too long is solved.

Description

technical field [0001] The invention relates to an indoor ventilation device, in particular to an indoor ventilation device with a controllable ventilation rate. Background technique [0002] Indoor ventilation equipment can discharge the indoor air. For some manufacturers, the use of indoor ventilation equipment can effectively reduce the indoor dust content. In order to save electricity, different air dust content uses different motor speeds. This method increases the motor speed. Finally, the speed of the fan increases and the suction force from the ventilation duct increases, but the position of the entrance of the duct is fixed, resulting in an increase in the adsorption capacity that is not proportional to the increase in the effective dust collection area, that is, the adsorption force cannot be effectively increased to a certain strength. The absorption range of the entrance of the pipeline is improved. In view of this, the present invention proposes an indoor ventil...
