The invention discloses an ignition control system based on a jet oscillator, comprising a duty flame stabilizer, a plurality of jet oscillators arranged on the duty flame stabilizer, and a fuel system. The jet oscillator is connected to a duty area behind the duty flame stabilizer, and the fuel system sprays fuel into the inlet of the jet oscillator. The outlets of the inner channel and the outer channel are provided with paddles, and the paddles rotate around the outer wall of the inner channel. The paddles control the source of air entering the jet oscillator, and the active control of the oxygen content in the combustion chamber is realized, the oxygen content is increased, ignition is realized at a smaller oil-gas ratio, and the ignition boundary is widened; when the paddles are adjusted to a suitable position, the airflow entering the jet oscillator is adjusted, so that the oxygen content and fuel distribution in the duty area can be adjusted.

The utility model relates to the technical field of motors, and discloses a rotor assembly, a motor and a household electrical appliance, the rotor assembly comprises a rotating shaft, a plastic package body and an iron core, the plastic package body is connected to the rotating shaft, and the iron core is connected to the plastic package body; wherein the plastic package body is packaged between the rotating shaft and the iron core, the iron core surrounds the rotating shaft, at least one of the two end faces of the plastic package body is provided with a thickness reducing hole in the axial direction of the rotating shaft, and the thickness reducing hole is located between the rotating shaft and the iron core. The thickness reducing holes are formed in the end face of the plastic package body, the wall thickness of the position, between the rotating shaft and the iron core, of the plastic package body is reduced, the wall thickness of all positions of the plastic package body is uniform, shrinkage of all positions is uniform in the injection molding process, and the defects of internal shrinkage cavities, overlarge internal stress, uneven deformation and the like of the plastic package body are overcome; and the structural strength and the dimensional precision of the rotor assembly can be improved.

A matching structure of a movable tool bit and a fixed tool bit of a kitchen waste machine barrel assembly comprises the movable tool bit rotationally arranged in a barrel body and the fixed tool bit fixedly arranged in the barrel body, a plurality of tools with different heights are annularly arranged on the movable tool bit, and the fixed tool bit comprises a plurality of blades which are arranged on the barrel body and have different heights. And when the movable cutter head rotates, the cutters with different heights are respectively matched with the blades with different heights. A plurality of cutters with different heights are annularly arranged on the movable cutter head, the fixed cutter head comprises a plurality of blades which are arranged on the can body and have different heights, and the cutters with different heights are respectively matched with the blades with different heights when the movable cutter head rotates, so that garbage can be sheared and crushed in all directions, and the movable cutter head and the fixed cutter head are simple in structure and convenient to use. The garbage crushing device is simple in structure and uniform in circumferential distribution, has a garbage crushing function in each direction, avoids the situation that garbage cannot be crushed, and is short in garbage crushing time and high in working efficiency by combining continuous circulating work of the movable cutter head and the fixed cutter head.

The present application relates to air purification and clean room ventilation technical field, more specifically, the present application relates to a kind of low wind resistance high flux chemical filter structure, including the shell of filter section in air conditioning unit installation, the shell is connected with the air inlet pipeline for conveying gas to be handled;The shell can make gas form vortex air curtain guide vane;First filter element capable of carrying out preliminary processing to gas is installed in the shell, vibration element capable of disturbing filter material in first filter element is installed in the shell, collection element capable of collecting broken filter material is provided in the shell.The present application is through annular self-adapting guide, rotating vibration double-layer filter bed, variable porosity thin layer filter bed and multi-stage cooperation of cabin self-vibration fine filter, make the airflow distribution uniform entering filter layer, filter material utilization rate is high, under the premise of not increasing module external dimension, significantly reduce unit wind volume pressure drop and slow down the growth of pressure difference with running time, realize low wind resistance, high flux chemical filtration.
