The utility model provides a kind of electric hair dryer, it includes shell and hair dryer piece.The electric hair dryer of the utility model, shell inside is equipped with multiple independent air duct, each air duct independently sets air inlet, air outlet and hair dryer piece, airflow can independently circulate in respective air duct inside, effectively ensure the air speed, air pressure stability of each direction air outlet, improve overall hair drying efficiency;And, the air outlet direction of the air outlet passage formed by the electric hair dryer corresponding multiple air ducts is different, so that user can realize the coverage of multiple area airflow without frequently adjusting the position of electric hair dryer, to make airflow distribution more uniform, range more extensive, to effectively cover the different area of object to be blown dry, improve user's use experience.

This utility model discloses a hot air circulation pipeline diversion and distribution device, relating to the field of pipeline diversion technology. It includes a diversion box with an air inlet on its bottom wall and branch interfaces evenly inserted on its top. Each branch interface has a connecting cylinder fixedly connected to its inner wall, and a crossbar fixedly connected to its inner wall. By incorporating connecting cylinders and connecting balls, this utility model prevents gas backflow during use, ensuring unidirectional hot air flow in the designed direction. This maintains stable airflow and pressure in each branch pipeline, preventing process effects caused by unstable airflow. The device also features threaded sleeves and protruding plates, allowing for quick and easy disassembly of damaged branch interfaces during maintenance. This significantly improves the efficiency of maintenance.

The utility model discloses a multifunctional air volume control film blowing device for mulching film processing, and relates to the technical field of mulching film processing. The device comprises a bottom plate, an extrusion device is arranged at the top of the bottom plate, an air blower is fixedly connected to the top of the extrusion device, a ventilation box is communicated to the top of the air blower, an air suction pipe is communicated to the top of the ventilation box, and a transmission motor is fixedly connected to the interior of the ventilation box. The transmission motor drives the gear to be meshed with the fluted disc to drive the wind shield to rotate, the opening degree of the ventilation groove can be accurately adjusted, accurate control over the film blowing air volume is achieved, the problem that a traditional device cannot adjust the air blowing volume is solved, airflow leakage is effectively prevented through cooperation with a sliding sealing structure of the rubber sealing ring and the sealing groove, and the service life of the device is prolonged. And stable air pressure under different raw materials and process conditions is ensured, so that the film bubble forming quality is improved, the mulching film is more uniform in thickness and smoother in surface, and meanwhile, the energy consumption and the production rejection rate are reduced.
