Title:
AIR BLOWING DEVICE AND TOWER FAN
Document Type and Number:
WIPO Patent Application WO/2022/001043
Kind Code:
A1
Abstract:
Disclosed are an air blowing device and a tower fan. The air blowing device comprises a housing (10), a wind wheel assembly (30) and a heating component (40), wherein the housing is provided with an accommodating cavity (11), and an air inlet, a first air outlet (21) and a second air outlet (22) which are all in communication with the accommodating cavity; the wind wheel assembly and the heating component are both arranged in the accommodating cavity; the wind wheel assembly comprises a first wind wheel (31) and a second wind wheel (32); the first wind wheel is located on one side of the first air outlet, such that airflow in the accommodating cavity flows out of the first air outlet under the action of the first wind wheel; the second wind wheel is located on one side of the second air outlet, such that airflow in the accommodating cavity flows out of the second air outlet under the action of the second wind wheel; the heating component is located between the second air outlet and the air inlet, such that at least some of the air passing through the second air outlet is heated by means of the heating component; and the first wind wheel and the second wind have a synchronous rotation state and an independent rotation state. By means of using the air blowing device, the problem of the comfort of a heating and cooling tower fan in some embodiments being poor can be solved.
