The utility model belongs to the technical field of range hoods, and particularly relates to a range hood with air conditioner fresh air, which comprises a range hood main body, a bottom plate fixed at the bottom end of the range hood main body and an air conditioner fresh air component fixed at the top end of the range hood main body, an air guide pipe; the exhaust head is fixed at the bottom end of the bottom plate and communicated with the air guide pipe, the bottom surface of the exhaust head is an inclined surface, and an air outlet hole is formed in the inclined surface; the spoilers are rotationally mounted in the air outlet holes; the driving mechanism is used for driving the spoiler to rotate; the filtering mechanism is slidably mounted at the position, close to the air inlet connector, in the outer shell; according to the utility model, through the designed inclined-surface exhaust head and the rotatable spoiler, air flow is diffused along the inclined surface, and dead angles are reduced; meanwhile, the angle of the spoiler is adjusted through the driving mechanism, the air outlet direction is changed, and dead zones such as wall corners and the rear of furniture are prevented from being directly blown to workers.

This invention discloses a linkage assembly, an air outlet structure, and an air conditioner. The linkage assembly includes a linkage rail and a linkage slider. The linkage assembly drives multiple blades to rotate synchronously. Multiple linkage sliders are spaced apart along the length of the linkage rail, and their positions on the rail are adjustable. Each linkage slider has a first mating groove that directly or indirectly engages with a blade, and these grooves respectively engage with multiple blades. According to the linkage assembly of this invention, the linkage assembly can change the airflow direction of the blades and adapt to adjustments in the blade spacing to meet user needs, thereby improving airflow efficiency and enhancing user comfort and experience.

The utility model discloses a drying oven tuyere structure which comprises a rotating cylinder body, a rotating head is rotationally installed on the rotating cylinder body, and an inner cavity of the rotating head is a first air channel with the width sequentially narrowing from the rotating cylinder body to the outside. The rotating cylinder is provided with a first mounting hole and second mounting holes located in the two sides of the first mounting hole, the rotating head is provided with a third mounting hole aligned with the first mounting hole and two arc-shaped holes located in the two sides of the third mounting hole, and the fastener penetrates through the third mounting hole and is locked on the first mounting hole. The limiting piece penetrates through the arc-shaped hole and is locked on the second mounting hole; a second air duct is formed in the rotating cylinder, a first mesh plate located at the inlet end of the second air duct is mounted in the rotating cylinder, a mounting plate is detachably mounted on the rotating cylinder, and a plurality of air inlet holes communicated with the second air duct are formed in the mounting plate; when different types of pole pieces are dried, the angle of the rotating head can be adjusted, so that the air outlet flow direction in the first air duct is changed, and the drying efficiency and effect are improved.

The application provides a bladeless fan, comprising: a shell provided with an air inlet and an air outlet which are in communication with the inside of the shell; and a fan assembly accommodated in the shell; wherein the air outlet is arranged in the middle region between the front end and the rear end of the shell. By arranging the air outlet in the middle region between the front end and the rear end of the shell, the air outlet direction of the fan assembly is changed, and the air inlet and air outlet of the fan assembly are improved.
