6results about How to "Avoid moisture corrosion" patented technology

This utility model relates to the field of motor technology and provides a corrosion-resistant DC motor, including a motor body, an anti-corrosion shell, and a circulating cooling assembly inside the anti-corrosion shell. The circulating cooling assembly has at least one cooling fin, an inlet pipe, and an outlet pipe, both of which penetrate the anti-corrosion shell and extend to the outside. The motor body has a motor output shaft and a junction box. A sealed bearing is provided between the motor output shaft and the anti-corrosion shell. A terminal block is provided on the anti-corrosion shell near the junction box. This utility model features an anti-corrosion shell that isolates the motor body from the external environment, preventing direct contact and corrosion. The circulating cooling assembly inside the anti-corrosion shell carries away the heat generated by the motor body, preventing a temperature difference between the inside and outside of the anti-corrosion shell and keeping the inner wall of the anti-corrosion shell dry, thus preventing the motor body from getting damp.

This utility model discloses a novel drinking water device for cattle, belonging to the technical field of drinking water facilities for cattle. The utility model includes a base, a drinking device, a buoyancy-based water-blocking structure, and two side water-blocking structures. The drinking device is fixedly installed on the front of the base, providing stepped support. The buoyancy-based water-blocking structures are located on both sides inside the drinking device, utilizing the buoyancy within the device to seal it. This utility model utilizes the cooperation of pipes, pipe-blocking columns, and a buoyancy plate within the buoyancy-based water-blocking structure. When the water level in the cattle drinking trough drops, the buoyancy plate lowers with the water level, causing the pipe-blocking columns to move downwards via a vertical rod, allowing water from the storage box to automatically flow into the cattle drinking trough through the pipes. When the water level rises to a set height, the buoyancy plate, driven by buoyancy, moves the pipe-blocking columns upwards to seal the pipes. Automatic water filling is achieved without electricity, avoiding the risk of electric leakage that may occur with electric drives, while also reducing the complexity of cattle farming operations.

This utility model discloses an exhaust valve structure for a sparkling water machine, including an air passage body, an operating chamber and an exhaust chamber arranged on the air passage body, an exhaust valve, an exhaust valve rod, a first return spring, a second return spring, and an air guide pipe. During normal operation, the first return spring controls the operating valve rod to be located at the end of the operating chamber near the operating hole, and the driving valve section extends to its maximum distance outside the air passage body. At this time, the operating valve section does not contact the exhaust valve, and the exhaust valve completely seals the first connecting hole between the exhaust chamber and the operating chamber. When exhaust is required, a driving component arranged inside the sparkling water machine cooperates with the driving valve section and presses the driving valve section, causing the driving valve section to push the exhaust valve to move within the exhaust chamber. This allows the air intake channel to connect unobstructed with the exhaust hole in the exhaust chamber through the first connecting hole, thereby guiding the carbon dioxide gas in the sparkling water bottle to a specific area along the air guide pipe, thus preventing the moisture in the emitted carbon dioxide gas from corroding the parts.

The application discloses a two-port conductive contact connecting device and method of micro network fusion terminal and belongs to the field of electric connection. The two-port conductive contact connecting device of the micro network fusion terminal comprises an upper conductive connecting part installed on a terminal device and a lower conductive connecting part provided with a wire, wherein the upper conductive connecting part is connected with the lower conductive connecting part, further comprising a lock catch used for mounting the lower conductive connecting part to the upper conductive connecting part, a rectangular slot is formed on the lower conductive connecting part, the rectangular slot is internally provided with a reset assembly and a plurality of piercing units, and the reset assembly provides a rebound force which can effectively prevent the lock catch from falling off. In addition, the glue flowing out of the rubber strip is combined with the extrusion of the reset assembly to realize all-round filling, thereby effectively improving the sealing effect and avoiding the internal conductive elements from being corroded due to damp.
