An energy-saving and environmentally friendly ventilation device

Abstract

This utility model discloses an energy-saving and environmentally friendly ventilation device, including a main body and a scraping mechanism disposed on one side of the main body. The main body includes a main frame, and the scraping mechanism includes slide rails fixedly connected to the outside of the main frame and symmetrically arranged. A base frame is fixedly connected to the bottom of the slide rails, and a sliding arm is slidably connected to the outside of the slide rails. A screw is threadedly connected to the inside of the sliding arm, and a knob is fixedly connected to one end of the screw. After holding the handle, the sliding arm is pulled up along the outside of the slide rail, which drives the brush to scrape the surface of the mesh cover. When the sliding arm moves to the top and contacts the bottom of the limiting plate, the handle is released. At this time, the sliding arm slides down and resets under the influence of gravity. During this process, the mesh cover is scraped twice, thus completing the overall cleaning of the outside of the mesh cover in one operation. This effectively avoids the need for multiple operations by personnel, greatly reducing the physical exertion of personnel while ensuring cleaning efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of ventilation equipment technology, and specifically relates to an energy-saving and environmentally friendly ventilation device. Background Technology

[0002] Ventilation devices often achieve energy conservation and environmental protection through variable frequency speed control technology. Through the variable frequency controller, the fan speed is automatically adjusted according to the indoor air quality, such as carbon dioxide concentration, humidity, PM2.5 content, or the activity of people. It runs at high speed when a large air volume is needed, and runs at low speed or stands by when no one is around or the air quality is good, so as to avoid energy waste.

[0003] During long-term use, some existing energy-saving and environmentally friendly ventilation devices tend to accumulate a large amount of dust on the leeward side of their protective mesh covers due to airflow. Traditional manual cleaning methods are limited by the complex shape of the mesh surface and usually require multiple operations, making it difficult to complete the cleaning in one go. This not only significantly increases the physical exertion of operators but also seriously affects cleaning efficiency. Utility Model Content

The outer surface of the handle 5 is treated with a deburring process, which can effectively facilitate personnel to directly hold and pull the sliding arm 202.

[0023] In this utility model, preferably, a limiting piece 6 is fixedly connected to the top of the slide rail 201, and a main frame 101 is fixedly connected to one side of the limiting piece 6, which can effectively limit the upward movement of the sliding arm 202 and reduce the risk of falling off due to excessive movement.

[0024] In this utility model, preferably, the brush 206 is made of flexible material, and a sliding piece 205 is fixedly connected to one side of the brush 206, which can effectively reduce the wear on the surface of the mesh cover 106 during the scraping process.

[0025] The working principle and usage process of this utility model are as follows: During use, the main frame 101 is installed at the predetermined position using the screw holes provided in the mounting bracket 102. After a period of use, when a large amount of dust adheres to the outer surface of the mesh cover 106, the outer wall of the knob 204 is directly pinched, and the screw 203 is rotated within the moving arm 202. This causes the screw 203 to move the moving plate 205 until the brush 206 fully contacts the outer wall of the mesh cover 106. Holding the handle 5, the moving arm 202 is pulled upwards along the outside of the slide rail 201, causing the brush 206 to scrape the surface of the mesh cover 106. When the moving arm 202 moves to the top and contacts the bottom of the limiting plate 6, the handle 5 is released. At this time, the moving arm 202 slides down and resets due to gravity, during which the mesh cover 106 is scraped a second time. Thus, the entire outer surface of the mesh cover 106 is cleaned in one operation, effectively avoiding the need for multiple operations by personnel. This significantly reduces physical exertion while ensuring cleaning efficiency.
