Cutterhead assembly and mower
The application relates to the technical field of lawn mowers, in particular to a cutterhead assembly and a lawn mower. The cutterhead of the cutterhead assembly is provided with a driving part, an annular supporting part and an annular mounting part from inside to outside, the supporting part is connected with the driving part in an inner ring and connected with the mounting part in an outer ring; the driving part is connected with a driving unit, the outer ring of the mounting part is provided with cutting blades, the supporting part is provided with one or more through holes, and when the cutterhead rotates, the air flow velocity on the side of the supporting part close to the ground is smaller than the air flow velocity on the side of the supporting part far from the ground. When the cutterhead rotates, the air flow velocity below is higher, an upper-lower pressure difference is formed according to the Bernoulli principle, a stable air flow from top to bottom is constructed, the upward movement of grass stems is blocked, and the broken grass stems entering the upper part of the cutterhead can be quickly discharged to the ground in cooperation with the through holes. The application effectively solves the problem of grass stem winding around the motor output end in the long-term use of the cutterhead of the lawn mower.

Elastic metal plastic bearing bush, bidirectional thrust bearing and pumped storage unit
PendingCN119532321AImprove carrying capacitySolve the lack of spaceShaftsMachines/enginesThrust bearingMechanical engineering
The invention discloses an elastic metal plastic bearing bush, a bidirectional thrust bearing and a pumped storage unit, and relates to the technical field of thrust bearings of pumped storage units. The problems that an existing bidirectional thrust bearing is low in bearing capacity and high in bush temperature are solved. The bearing bush comprises a bush body, one side of the bush body is an oil outlet side, the other side of the bush body is an oil inlet side, the oil outlet side and the oil inlet side are each provided with an inclined face inclining towards the direction close to the bush body, and the circumferential length of each inclined face is one third of the circumferential length of the bush body. The inclined planes are arranged on the oil inlet side and the oil outlet side respectively, when the tile body is in an inclined state under the action of fluid dynamic pressure, the inclined plane on the oil outlet side can incline towards the direction close to the tile body, and the inclined planes are approximately parallel to the runner plate after being inclined, so that the influence of low bearing capacity caused by concave deformation of the elastic metal plastic tile surface is counteracted; enough space between the oil outlet side and the runner plate is ensured, so that the thickness of an oil film on the oil outlet side is correspondingly increased, the bearing capacity of the bearing is improved, and the bearing temperature is reduced.

An EGR check valve and an EGR system
ActiveCN224282797UOpen resistance is smalllarge opening angleInternal combustion piston enginesExhaust gas recirculationExhaust fumesCheck valve
This application discloses an EGR one-way valve and an EGR system. The EGR one-way valve includes a base and a valve plate. A rotating shaft is provided at the fixed end of the valve plate, and a bushing is provided on the base. The valve plate is rotatably connected to the base through the bushing that cooperates with the rotating shaft. The opening of the valve plate of the EGR one-way valve disclosed in this solution is affected by the friction between the rotating shaft and the bushing. The friction between the rotating shaft and the bushing is much smaller than the restoring force generated by the deformation of the valve plate in related technologies, which reduces the opening resistance of the valve plate and increases the opening angle of the valve plate, thereby reducing the exhaust gas resistance and helping to improve the engine EGR rate. By changing the fixing method of the valve plate, the valve plate does not deform during the opening process, and the valve plate does not block the opening area, increasing the opening area at the same opening angle. At the same time, the valve plate does not deform, reducing the risk of the valve plate breaking due to frequent opening and closing, and extending the service life of the valve plate.

Atomizer, method for making atomizer, and electronic cigarette
ActiveCN115104778Bescape efficientReduction in the number of bouncesTobaccoHazardous substanceElectronic cigarette
An atomizer, a method for making an atomizer, and an electronic cigarette. The atomizer comprises a porous ceramic body and a heating body. The porous ceramic body comprises a liquid guide area and an atomization area. Liquid is introduced into the atomization area through the liquid guide area. The heating body is used to heat the porous ceramic body so that the liquid is heated and atomized in the atomization area. An escape hole is formed on the outer surface of the atomizer. Particles formed by liquid atomization escape to the outside through the escape hole. Along the depth direction of the escape hole, the width dimension of the bottom of the escape hole is not greater than the width dimension of the opening, so that the escape hole has a larger opening angle, the number of rebounds of the particles in the escape hole is reduced, the escape impedance is reduced, and the efficient escape of the particles can be achieved, so as to avoid the particles staying in the escape hole and being heated for too long to produce harmful substances.
