The application belongs to the technical field of medical devices, and discloses an atomization mask which comprises a sealing member and a supporting member, the sealing member has a fitting end for fitting a patient's face and a supporting end opposite to the fitting end, the fitting end is provided with an accommodation port capable of simultaneously accommodating the patient's mouth and nose, the supporting end is provided with a convex portion capable of covering at least part of the patient's nose and a mounting port located below the convex portion, the supporting member is arranged in the mounting port and jointly spliced with the sealing member to form a delivery cavity, the supporting member is provided with a connecting hole for connecting an atomization cup, the connecting hole is in communication with the delivery cavity, the rigidity of the supporting member is greater than that of the sealing member, thereby increasing the deformation ability of the sealing member, so that the sealing member can adapt to the nose contours of various patients, the sealing property between the atomization mask and the patient's face is increased, and the atomization treatment effect on the patient is ensured.

This invention relates to a planetary roller driven intelligent robot joint, belonging to the field of intelligent robot technology. It features an active, controllable sealing assembly consisting of a sealing strip and a sealing cylinder, with the sealing cylinder integrated into the outer wall of a fixed block. The sealing strip is installed in a sealing groove communicating with the sliding block, allowing the sealing strip to actively extend and retract according to the sliding block's movement. When the sliding block retracts inward to reset, the sealing strip is compressed and deformed, tightly adhering to the outer wall to achieve a dynamic seal. When the sliding block extends outward, the sealing strip releases the compression and springs back to its original shape while maintaining a sealing fit. This transforms the passive alternating friction caused by traditional interference fits into active, time-division controllable contact, fundamentally avoiding fatigue aging and failure caused by the long-term alternating deformation of the sealing strip with the sliding block.

This invention discloses a press-fitting device for bushings based on ultrasonic vibration, comprising a frame base, a hydraulic cylinder, a transducer assembly, a mandrel, and a clamping assembly. The hydraulic cylinder is mounted on the frame base to provide axial pressing force. The transducer assembly is mounted on the output end of the hydraulic cylinder to generate high-frequency mechanical vibration and transmit it to the mandrel. The mandrel has a tapered feature for inserting into a bushing pre-placed in the inner hole of the workpiece. The clamping assembly is mounted above the frame base to clamp and fix the workpiece. The hydraulic cylinder drives the transducer assembly and the mandrel to move axially, and the high-frequency vibration is transmitted through the mandrel to the contact interface between the mandrel and the bushing, converting static friction into dynamic friction and reducing pressing resistance. This invention also includes a movable joint assembly for flexible connection, a pressure sensor for real-time monitoring of the pressing force, and a rubber clamping plate for adaptive centering in the clamping assembly. This invention effectively reduces pressing force and improves pressing quality and efficiency.
