This application relates to a top-blown vaporizer, applied in the field of vaporizers. It includes a vaporizer body with a plurality of heat exchange tubes forming a heat exchange channel. A mounting frame is mounted on the vaporizer body, and a first damping pad is mounted on the mounting frame. A fan is mounted on the first damping pad, with the fan's outlet corresponding to the heat exchange channel. The technical advantages of this application are: the first damping pad absorbs the high-frequency vibrations generated during fan operation, reducing the possibility of vibrations being directly transmitted to the mounting frame and vaporizer body, reducing resonance between the fan and the mounting frame, improving the overall stability of the vaporizer body, and simultaneously reducing the possibility of high-frequency vibrations being transmitted and amplified through rigid connections during fan operation, thus reducing mechanical noise generated by fan vibration.

This invention proposes a seed metering chamber that directly drives the seed disc rotation using an axial flux motor, belonging to the field of agricultural machinery technology. It solves the shortcomings of existing seed metering mechanisms, such as reliance on mechanical shaft transmission, long transmission chains, poor transmission stability during operation, and high noise levels. In this invention, housings A and B are interconnected to form a seed metering cavity, with the seed disc disposed inside the cavity. A top seed wheel is located inside housing A and on one side of the seed disc, adjacent to the seed disc to form a seed metering structure. An axial flux motor is disposed on one side of housing B, with its output end facing the seed metering cavity and connected to the seed disc. The output end of the axial flux motor has a protruding structure, and the seed disc has a corresponding groove structure. The protruding structure is embedded in the groove structure to drive the seed disc to rotate. This invention is applicable to precision seeding operations in agricultural seeding equipment for quantitative separation and stable seed discharge.
