Fresh air device and fresh air service system

Abstract

The invention provides a fresh air device and a fresh air service system. The fresh air device comprises an outdoor unit arranged outdoors, an air filtering device arranged indoors, a connecting assembly and a control assembly. The air filtering device comprises a filter element identity identification module. The control assembly comprises a controller and a filter element identity identifier, the filter element identity identifier can read a filter element identity identification in the filter element identity identification module after the air filtration device and the connection assemblyare assembled together and send the information to the controller, the controller allows a motor of a fan in the outdoor unit to operate normally when it is confirmed that the read filter element identity identification has been authorized for use, and the controller disables normal operation of the motor in the fan in the outdoor unit when it is confirmed that the read filter element identity identification is not authorized for use. Thus, the non-legitimate filter element bearing device cannot be normally used.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a fresh air device and a fresh air service system. Background technique [0002] The rapid development of the existing economy has greatly satisfied the material needs of residents, but at the same time it has also brought serious environmental pollution, mainly reflected in air pollution, water pollution and soil pollution. In particular, the performance of air pollution has been particularly prominent in recent years, and the frequent occurrence of smog has even seriously endangered the health of residents. In order to improve the indoor air quality of homes, offices, etc., various types of fresh air devices have emerged. It introduces filtered clean fresh air into the room through ventilation and supplements oxygen, thereby improving the comfort of the living space. Reduce the level of pollutants in the air. [0003] At present, the commonly used fresh air devices o...

Problems solved by technology

[0005] 1. It is difficult for traditional fresh air devices to achieve a balance in terms of purification effect, purification area, product volume and noise generated by the product. That is, if you want to have a good purification effect and a large purification area, it is best to use glass fiber filter paper. Okay, but if the wind resistance is large, you need to use a high-power fan, and the high-power fan will inevitably lead to a large volume of the product and the noise generated; if you want a product with low noise or small size, you need to use a low-power fan. It is suitable for chemical fiber filter paper, but not suitable for glass fiber filter paper. The impact of this is that the purification effect is poor or the purification area is small;

[0006] 2. The traditional wall-mounted fresh air device will become less and less effective with the use of time, so the filter must be replaced in a short period of time. The operation of replacing the filter is troublesome, wastes materials, and costs high;

[0007] 3. After the traditional wall-mounted fresh air device or split-type fresh air device is used or stopped for a period of time, the inside and surface of the indoor unit will be dirty, and the inside is not easy to clean. When the purified clean air is released into the air through the internal unit, it is easy to cause secondary Pollution; although the surface of the body is easy to clean, it tends to become old and dirty over time, making it unsightly; etc.

The filter element is installed in the inner machine. From the perspective of product production, at least two main components are required, namely the replaceable filter element and the inner casing. Multiple molds need to be prepared, which is inconvenient for production, installation, and maintenance, and the cost is also high.

After installing a traditional wall-mounted fresh air device or a split-type fresh air device, if the user is not satisfied with its appearance and wants an ideal appearance, it is necessary to replace the fresh air device as a whole, or at least replace the internal unit of the fresh air device. The cost, the operation is also troublesome
