Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a high-performance air purification device. Background technique [0002] The problem of fine particle pollution in the air has been gradually recognized by people, and air purification devices such as air purifiers are used more and more. Most air purification devices use a combination of an air filter and an airflow drive device. The airflow drive device drives the air to flow through the air filter to obtain the basic structure of the purification effect. The following part of this specification will refer to this structure as "basic structure". [0003] For an air purification device with a basic structure, air volume, noise, and efficiency are three important performance indicators. The larger the air volume, the better the purification effect, the lower the noise, the better, and the higher the filtration efficiency, the better, but these three performance indicat...

Problems solved by technology

[0013] 1. It has a shell or a specific overall structure, which is used to install components, form airflow channels and similar purposes. This problem exists in the above-mentioned prior art. This problem limits the expansion of air volume and is also useful for performance optimization in various aspects. limit;

[0014] 2. Take the combination of "fan + filter corresponding to the fan" as the basic functional unit, and use different combination numbers and forms to obtain different effects, such as existing technologies 2, 4, 5, 6, and 7. This problem, in this way of thinking, there is always a corresponding relationship between a certain airflow drive device and a specific air filter, which limits the performance improvement in many ways;

[0015] 3. The positions of the air inlet and outlet are adjacent and the airflow cannot be effectively separated, resulting in a short circuit in the airflow path. When used indoors, the overall air circulation and filtration of the working space cannot be effectively realized. This problem is installed at the air outlet. Filters are especially obvious, as existing technologies 1 and 3 have this problem;

[0016] 4. It is difficult to use a real high-efficiency air filter or its performance is low in terms of air volume and lifespan

High-efficiency air filters can provide excellent filtration efficiency, but the resistance is relatively high. As far as the structure of most existing air purification devices is concerned, direct use of real high-efficiency air filters will have low air volume, high noise, and short life Many other problems, practicality is not enough

[0017] The above-mentioned existing technologies, none of them have been able to optimize as many aspects as possible in terms of air volume, noise, efficiency, volume, energy consumption, airflow path, etc., and at the same time minimize the unfavorable factors brought by the optimization method. Some performance indicators have been improved, but caused other problems or retained the deficiencies of the original technology

Existing technologies for air purification devices still have much room for improvement
