The invention provides a waterproof fastening shell. The waterproof fastening shell comprises an upper shell body and a lower shell body, wherein the upper shell body comprises an upper bottom surfaceand a waterproof glue binding wall which surrounds the upper bottom surface for one circle and protrudes downward; the waterproof glue binding wall is provided with a plurality of convex clamping hooks; the lower shell body comprises a lower bottom surface, and a first side wall and a second side wall which surround the lower bottom surface for one circle and protrude upward; the first side wallis arranged at the outer side of the second side wall; a clamping hook groove matched with the clamping hooks is formed between the first side wall and the second side wall; a U-shaped groove for containing the waterproof glue binding wall is formed in the second side wall. With the adoption of the technical scheme, the clamping hooks and the clamping hook groove are adopted, and the shell is clamped without the need of an additional tool clamp, so that the time and the clamp cost are reduced; the shell body is fastened by utilizing the clamping hooks, and rebound stress can be balanced, so that the risk that waterproof glue is separated from the two shells is effectively reduced; an additional screw locking procedure is not needed, so that the procedure cost is reduced; the waterproof glue is used for preparing a waterproof layer, so that the risk that a waterproof ring is not assembled in place is also avoided.

The invention relates to the technical field of ink-jet printers, and particularly relates to an ink box. The ink box is detachably installed on an installation part and comprises a first clamping position and a second clamping position which are oppositely arranged on the two sides of the ink box, the first clamping position is matched with a clamping groove of the installation part, the ink boxfurther comprises a movable part, the second clamping position is connected to the movable part, the second clamping position comprises a first clamping part and a second clamping part, when the ink box is installed on the installation part, the movable part can move so that the first clamping part and the second clamping part can be connected with the installation part in a clamped mode at the same time. By means of the ink box, and the risk that the ink box is released due to excessive acting force when the ink box is installed on the installation part is avoided.

The invention relates to a air drain control lever for operating air drain, wherein the air drain control lever has a base body and a joint element which is set on an end region of the base body and is designed to keep the distance between the base body and the air drain below a maximum value able to be preset as the base body moving.

Described is an atomizing nozzle having a relatively small frontal area permitting insertion of a nozzle into small diameter medical conduit(s). A body of a preferred nozzle has a characteristic size (e.g., cross-section diameter) of less than about 0.2 inch (0.5 cm). The nozzle body is typically carried on an extension member, which can be transversely flexible to permit passage of a nozzle body through a tube and along a nonlinear path. The nozzle body is typically connected to an extension member by way of a lap joint associated with the nozzle body. Preferred embodiments have a De / O ratio of less than 12.0, a Db / O ratio of less than about 18, and a Db / De ratio of less than about 1.1. Certain embodiments include a swirling chamber disposed upstream of the ejection orifice and having a proximal wall with a portion configured to at least approximate a portion of a dome, or other curved surface.
