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 test kit comprising an annular magnet (2), a ball (3), a magnetic bar (4), an electromagnetic coil (5), a box body (6), an air inlet (7), a liquid outlet pipe (8) and a sealing gasket (9), wherein the liquid outlet pipe (8) is located on the bottom face of the box body (6), the top of the liquid outlet pipe (8) is fixed to the box body (6), the cylindrical magnetic bar (4) is arranged in the middle of the liquid outlet pipe (8), the bottom of the magnetic bar (4) is fixedly connected to the ball (3), the round sealing gasket (9) is arranged in a hole in the lower portion of the liquid outlet pipe (8), a spherical pit is provided in the center of the top of the sealing gasket (9), a liquid outlet (1) is provided in the bottom of the pit, the bottom of the ball (3) matches and is tightly attached to the spherical pit in the top of the sealing gasket (9), the annular magnet (2) is fixed to the bottom face of the liquid outlet pipe (8), and the electromagnetic coil (5) is fixed on an outer face of the liquid ou

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.
