Improved structure of circulation fan

The present invention relates to an improved structure of a circulating fan, in particular to a ceiling-mounted circulating fan for setting in an indoor ceiling, and more particularly to an improved structure of a circulating fan capable of automatically detecting temperature and adjusting air volume.

In summer, the temperature is very hot. Air conditioners are usually used to provide indoor air-conditioning to reduce indoor temperature. However, air circulation is not easy to cause uneven indoor temperature. Do your best. In order to solve the problem of indoor temperature unevenness, there is a ceiling-type circulating fan on the market for adjusting indoor airflow. The circulating fan is mainly installed on the indoor ceiling, and the operation of the internal fan can attract adjacent ceilings. The upper layer of air enters the circulation fan, and the air in the circulation fan is sent out toward the ceiling, so that the upper and lower air in the room form a state of circulation convection, instead of the cool air effect of the general fan, if used in conjunction with cold air, Effectively help the air-cooling to spread quickly, let the air-conditioning evenly distribute, and the cold room effect is better, which can avoid the above-mentioned situation of cold and hot.

The existing circulation fans can accept the user to adjust the wind speed, generally can be divided into breeze, stroke and strong wind, and even more segments of wind speed change, so that the circulation fan provides the air volume to meet the user's needs. However, when the indoor temperature changes with the outdoor climate, the user must actively adjust the wind speed of the circulating fan. For example, when the outdoor climate temperature drops suddenly, the indoor temperature will also decrease. At this time, if the circulation fan is still supplied with the wind speed before the climatic temperature dips, the temperature of the circulating fan air supply will decrease with the outdoor temperature. The user feels cold. On the other hand, when the outdoor climate temperature rises, if the circulation fan is still supplied with the wind speed before the climatic temperature rises, the temperature of the circulating fan air supply also rises with the outdoor temperature, making the user feel stuffy. Therefore, the user must pay attention to the changes of the outdoor climate at any time, and immediately make appropriate adjustments to the wind speed of the circulating fan. The convenience of use is still insufficient, especially when the user sleeps during the night, if the user fails to get up immediately The wind speed of the circulating fan is likely to cause the user's body to get cold and get sick.
