This utility model discloses a bladeless fan with a horizontally arranged annular air duct for both heating and cooling. It includes a main housing with an air inlet on one side. Inside the main housing is a fan with its air inlet aligned with the air inlet. A baffle assembly for balancing the airflow on both sides is located at the upper end of the annular air duct. This horizontal arrangement, aligning the fan's air inlet with the air inlet on the main housing, minimizes the space occupied by the fan installation, saving more space for other components and structures. This results in a smaller, more compact bladeless fan, improving space utilization. The cooperation of baffles A and B ensures that even if the airflow from the horizontally arranged fan's outlet into the left and right annular air ducts differs, the baffles can buffer the side with the stronger airflow, maintaining uniform airflow from both sides and preventing wind noise caused by differences in airflow strength.

This invention provides a pet drying box air outlet structure and a pet drying box itself. The pet drying box air outlet structure includes a drying box body, a volute fan, and a heating structure. The drying box body is provided with a hot air outlet chamber, a guide chamber, and a pet holding chamber connected in sequence. The volute fan and the heating structure are both installed in the hot air outlet chamber, with the heating structure installed downstream of the volute fan. The guide chamber and the hot air outlet chamber are connected by a ventilation plate. After the volute fan generates air, the heating structure raises the air temperature to form hot air. The hot air enters the guide chamber through the ventilation plate and, guided by the guide plate, flows to the pet holding chamber to dry the pet. This invention, through the design of hot air sequentially passing through the hot air outlet chamber, the guide chamber, and the pet holding chamber, forms a complete air outlet path. Combined with the guiding effect of the guide plate, the raised bottom of the air outlet plate, and the concave design of the air outlet, the invention achieves a uniform air outlet effect in the pet drying box.
