Description

Technical Field

[0001] The present invention belongs to the technical field of air purifiers, and in particular refers to an air purifier with a voice control function. Background Art

[0002] Air purifiers, as a modern household appliance, are designed to effectively remove pollutants such as dust, pollen, bacteria, viruses, and harmful gases from indoor air through specific filtering and purification technologies, thereby improving indoor air quality and protecting people's respiratory health. With the advancement of technology, air purifiers have gradually incorporated more intelligent elements, such as air quality monitoring and intelligent control, making them more convenient and efficient to use.

[0003] However, there are still some urgent problems to be solved in the design and use of existing air purifiers. In particular, the fan inside the air purifier, as a key component for generating airflow, will generate certain noise during its operation. This noise not only affects the user experience, but more importantly, in an air purifier with voice control function, the noise generated by the fan can easily interfere with the voice recognition of the microphone. When the noise is too loud, the voice recognition accuracy of the microphone will drop significantly, resulting in the inability to accurately recognize and execute user commands, thereby affecting the intelligent control effect of the air purifier.
