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.
