Abstract: The present application provides a gas inlet structure for a reagent kit, which includes a gas inlet connecting pipe and a plugging pipe arranged at one end of the gas inlet connecting pipe. The plugging pipe is provided with a gas nozzle plug, and the plugging pipe is in interference fit with the gas nozzle plug. The gas nozzle plug is provided with a gas inlet blind hole that is arranged along an axis direction of the gas nozzle plug, and an opening end of the gas inlet blind hole faces the gas inlet connecting pipe.
Abstract: A sealing valve comprises a sealing valve body (1). The sealing valve body (1) is provided with a cylindrical valve hole (2), and a bottom end of the cylindrical valve hole (2) is provided with a frustum hole (3). The frustum hole (3) is arranged coaxially with the cylindrical valve hole (2), and a small bottom end of the frustum hole (3) is in communication with the bottom end of the cylindrical valve hole (2). The sealing valve is controllable over the opening and closing of a nozzle.
Abstract: A liquid outlet device for reagent kit includes a spray pipe and a nozzle that is arranged at one end of the spray pipe, where each blocking strip extends along an axial direction of the spray hole and one end of each blocking strip is provided with a shoulder that extends towards a center of the spray hole. The spray pipe includes a spray pipe body, a plurality of blocking strips and a magnet bar that is movable along the axial direction of the spray hole in a space defined by the shoulders and the blocking strips. The nozzle includes an annular sleeve connected with the spray pipe body through threaded connection or clamped connection, an end plate, a nozzle pipe, a conical nozzle opening and an annular blocking flange.
