Household energy-saving ventilation equipment

Abstract

The invention discloses household energy-saving ventilation equipment which comprises a ventilation device shell. A driving motor is fixedly installed on the surface of the ventilation device shell, the interior of the ventilation device shell is divided into an air inlet cavity and an air exhaust cavity, ventilation pipelines are fixedly connected to the side walls of the air inlet cavity and the air exhaust cavity correspondingly, a filter screen is fixedly connected onto the inner wall of the other side of the air exhaust cavity, a coarse screening plate is arranged on the surface of the air inlet cavity, multiple anti-blocking mechanisms are arranged in the coarse screening plate, a rotating shaft is rotationally arranged on the inner wall of the air inlet cavity, one end of the rotating shaft is fixedly installed at the output end of the driving motor, and the rotating shaft is fixedly sleeved with multiple fixing tables. Compared with the prior art, according to the household energy-saving ventilation equipment provided by the invention, movable balls can shake under the action of airflow, the shaking amplitude of the movable balls can be enhanced through vibration springs, and most sand grains can be discharged out of screen holes in cooperation with movable shafts, so that the situation that the screen holes are blocked due to long-time operation of the equipment is avoided, and the influence of the sand grains on the operation efficiency of the equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of ventilation equipment, in particular to a household energy-saving ventilation equipment. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Fan is the customary abbreviation for gas compression and gas conveying machinery in China. Generally speaking, fans include ventilators, blowers, and wind generators. Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and induction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances Wait.

Problems solved by technology

[0003] The existing household ventilation device is equipped with a multi-layer filter device, which purifies the gas through the filter layer. During the use process, the filter layer is easy to accumulate dust, and the filter layer needs to be replaced regularly. The later maintenance is troublesome, and the ventilation device is set at Outdoor personnel are affected by wind noise and weather, causing the filter screen of the ventilation device to be blocked, affecting the normal operation of the equipment, requiring more power consumption for ventilation, which may seriously cause damage to the equipment. For this reason, we propose a household energy-saving ventilation The equipment is used to solve the above problems
