The hot air released at the ceiling of the bathroom passes through the reduced air outlet area and the speed increases, thereby blowing the air more strongly into the lower space. This helps to deliver hot air to lower areas in a shorter time, providing a faster heating effect. Also, toilets are often places in the home where temperature stratification is more pronounced, as the hot air will rise leaving cooler air. By blowing hot air at the ceiling and transferring it to a lower location, the hot air rises upward, and the rapid hot air flow causes air mixing at the lower location in advance, slowly rises, and can reduce temperature stratification, thereby achieving a more uniform temperature distribution in space and providing a more comfortable environment.

Second, the air outlet area of the air outlet is reduced, so that the air flow can be sent to a lower position under the condition that the power of the air source is not increased. This saves energy to some extent. And moreover, noise caused by the adoption of a high-power wind source is avoided, and a more comfortable environment is provided.

Third, the air outlet area of the air outlet can be adjusted according to the gear set by a user, a first temperature sensor and a second temperature sensor can be arranged at different heights in the toilet, the air outlet area required by the air outlet is dynamically determined according to the temperature changes of the height and the low position, when the warm air in the toilet low-altitude area is insufficient, the air outlet area of the air outlet is automatically reduced, and the hot air is conveyed to the sanitary low-altitude area more quickly.

Fourth, the air duct is divided into the first air duct and the second air duct, and the pressurizing cavity is arranged between the first air duct and the second air duct, so that air flow can be compressed by the pressurizing cavity, concentrated air is blown out from the air outlet, and the blowing speed and the blowing distance of the air flow are increased to a certain extent.
