5results about How to "Prevent affecting the cooling effect" patented technology

The invention discloses a sealed buffer mute roller washing machine motor which comprises a motor body, a sound insulation cover arranged at the bottom of the motor body, auxiliary buffer mechanisms located on the two sides of the sound insulation cover and a connection lubricating mechanism installed on one side of the output end of the motor body. The connecting lubricating mechanism is arranged on the rotating shaft, rotates along with the rotating shaft and is connected with an inner barrel of the washing machine; compared with the prior art, in the moving process of the mounting base, a reset pipe can be extruded, the reset pipe can twist to a certain degree under the action of a reset framework, a compression pipe and a sponge plate in the reset pipe can be extruded, oiling maintenance can be conducted after equipment operates every time, and the situation that a lubricating agent is dry due to long-time use is prevented; and meanwhile, the reset pipe can also expect the effects of blocking water vapor and the like, so that the rusting condition is avoided.

This application discloses an easy-to-clean cooking appliance and a method for cooking rice. The cooking appliance includes a pot body with a accommodating cavity and an inner pot. The pot body is equipped with a cooling device, and the inner wall of the accommodating cavity has air vents. The accommodating cavity has a first cooling side and a second cooling side, which are arranged opposite to each other. The cooling device has a first working state of sending airflow from the first cooling side to the second cooling side, and a second working state of sending airflow from the second cooling side to the first cooling side. The two working states alternate to allow cold air to circulate and cool the inner pot, causing condensation to form on the inner wall of the inner pot. The cold airflow in the accommodating cavity changes direction at regular intervals, alternately cooling the inner pot on the first and second cooling sides. This reduces the temperature difference between the two sides of the inner pot, improves the uniformity of cooling, ensures the non-stick effect of the inner pot in all areas, and enhances the user experience.

The utility model relates to the technical field of radiators, in particular to a novel radiator with a needle-column-shaped fin high-density arrangement structure, which comprises a substrate, the substrate is provided with at least one heat source contact surface, mounting holes are arranged at corners of the heat source contact surface so as to facilitate fixation, and a plurality of needle-column-shaped fins are arranged on the non-contact surface side of the substrate in a high-density vertical array mode. The cross section of the substrate is polygonal or circular, turbulent flow grooves (preferably V-shaped grooves or trapezoidal grooves) are formed in the top of the substrate so as to increase air turbulence and improve the heat dissipation effect, the projection area of the needle-column-shaped fins accounts for 70%-95% of the total area of the non-contact face of the substrate, the space is utilized to the maximum extent, the needle-column-shaped fins are made of copper alloy, aluminum alloy or metal matrix composite materials, and therefore the heat dissipation efficiency is improved. And the surface of the needle-column-shaped fin is covered with the nano oxide layer, so that the heat-conducting property and the corrosion resistance are enhanced, the needle-column-shaped fin can be arranged in a staggered array or hexagonal close packing manner, and the airflow path is optimized.

A portable AC-DC dual-purpose grounding resistance tester disclosed by the present invention comprises a box body, one side of the box body is fixedly provided with a heat dissipation fan, the other side of the box body is provided with a ventilation hole in a penetrating manner, one side of the heat dissipation fan is fixedly provided with a direction adjusting box, and the inner bottom of the direction adjusting box is slidably connected with a stirring frame. And a special-shaped disc is arranged above the shifting frame. A bidirectional motor is started, the output end of the bidirectional motor drives a cooling fan and a worm to rotate, the output end of a special-shaped disc drives a stirring frame to slide in a direction adjusting box, the stirring frame enables a stirring rod to swing along a limiting rod, an L-shaped sliding rod slides in the inner wall of the direction adjusting box, and during sliding, a stirring block pulls the L-shaped sliding rod to rotate in the direction adjusting box; and the flowing direction of heat dissipation air of the heat dissipation fan is changed, so that no-dead-corner cooling of electronic elements on the resistance tester body is realized, and the service life of the electronic elements is prolonged.
