Problems solved by technology

Most of the air volume adjustment methods currently used are manual control or electric control. Manual control cannot adjust the air intake in real time according to the external wind pressure, while electric control mostly uses the measurement signal of the sensor to adjust the air intake, which is relatively expensive.

Embodiment Construction

[0047] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] A kind of building anti-smog ventilation purifier The specific implementation mode is as follows figure 1 As shown, when the ventilator is ventilated with the outside, the outdoor air intake baffle 1 is opened, and the indoor air intake baffle 14 is closed. Outdoor air enters the ventilator through the lower part of the device, and then the air flows through the air volume regulating plate 2, which can rotate with the external wind pressure to automatically adjust the air volume. The air volume adjustment plate can also adjust its vertical position through the gear transmission mechanism, so as to change the air volume adjustment range and meet the individual needs for ventilation volume. Thereafter, the outdoor wind is filtered through the filter 4, and when the filter bypass baffle 3 is opened, the resistance of the air passing thro...

Abstract

The invention discloses a building haze prevention ventilation purifier. According to the ventilation purifier, the open degree of an air inlet is changed through rotation of an air volume adjusting plate under the action of air pressure, and thus the air inlet volume in an adjusting chamber is fed back. The adjusting plate conducts vertical position adjustment through a gear connection rod mechanism so as to change the area, impacted by air pressure, of the adjusting plate, and the needs for ventilation quantity in different seasons are met. A filter in the building haze prevention ventilation purifier is provided with an ash deposition indicating device and a scrap reminding device. The ash deposition indicating device can display the front and back differential pressure of the filter under real-time air speed so as to reflect the ash deposition degree of the filter. According to the scrap reminding device, when the filter is in a scrap state, a differential pressure linkage pointer makes contact with an air speed linkage pointer, a circuit is turned on, and an indicator light is on to remind a user of replacement of a filter screen. When the cleanliness of outdoor air is high, the ventilator bypasses the filter, the service life of the filter can be prolonged, and ventilation energy consumption is reduced. Through the building haze prevention ventilation purifier, indoor air quality of a building is effectively improved with small cost.

Description

technical field [0001] The invention relates to the field of indoor fresh air introduction and air purification, in particular to a building ventilation purifier under the background of smog. Background technique [0002] Our country's buildings are facing the "internal troubles" and "external troubles" of pollution. The "internal worry" is the release of a large amount of pollutants caused by the substandard interior decoration and furniture coating; the "external worry" is air pollution, especially the smog pollution that has received wide attention. The best way to alleviate "internal troubles" is building ventilation, but ventilation under the background of smog will introduce "external troubles". Therefore, it is necessary to develop a ventilation device that can not only introduce outdoor fresh air, but also intercept outdoor haze particles; and can meet the building ventilation requirements under non-haze weather conditions. [0003] At present, the most widely used...
