A breast pump (1), having - a milk container (2) with a cavity (3) for receiving expressed milk; - a breast shield (4) which has a breast funnel (5) and a nipple tunnel (6); - a connection element (7) which connects an opening (8) into the cavity (3) of the milk container (2) to the nipple tunnel (6); - an air release channel (9), the first end (10) of which is open to the cavity (3) of the milk container (2) and the second end (11) of which is open to the surroundings, wherein at least one portion of the air release channel (9) extends along the connection element (7), wherein the air release channel (9) extends at least in part along a portion at which the connection element (7) receives the nipple tunnel (6).

The invention relates to a closing screw (10) for a projectile (100), comprising a screw body (14) extending along a central longitudinal axis (M), wherein a channel (16) is formed in the screw body (14), which extends relative to the central longitudinal axis (M) from a first side (18) of the screw body (14) to a second side (20) of the screw body (14), wherein a closing element (22) is arranged in the channel (16), which closes the channel (16) and is configured in such a way that, when a defined limit pressure in the channel (16) is exceeded, the closing element (22) at least partially fails and at least partially releases the channel (16).

A head-maintenance device includes a suction cap to cap a nozzle surface of a head to discharge liquid, a suction unit to suck the inside of the suction cap, an air-release channel communicating with the inside of the suction cap, a lid to close an opening of the suction cap, and processing circuitry. The processing circuitry performs an air-release channel suction operation to close the air-release channel and suck the inside of the suction cap by the suction unit, with the opening of the suction cap closed by the lid, and open the air-release channel with the inside of the suction cap in a negative pressure.

The invention relates to the technical field of transformer protection devices, in particular to a transformer respirator anti-tripping device and a conduction control method. The device comprises a respirator, the respirator is connected with a breathing pipeline of the oil conservator through a flange I, the breathing pipeline of the oil conservator is further connected with an anti-bouncing device through a flange II, and a communicating connector connected with the breathing pipeline penetrates through the middle of a body of the anti-bouncing device. The two sides of the pressure release valve are connected with the negative pressure release channel and the positive pressure release channel through pressure release points respectively, and the pressure release valve is used for releasing positive pressure or negative pressure through the pressure release points when the respirator is blocked; the pressure release points are symmetrically arranged between the communicating connector and the negative pressure release channel and between the communicating connector and the positive pressure release channel respectively. Triple pressure protection is constructed through a respirator and double release channels, and the fault rate is reduced by 90%; pressure release is accurately controlled through a magnet and a spring, and positive pressure and negative pressure are independently treated; and the signal conduction mechanism is linked with the secondary junction box, so that remote alarm and state self-holding are realized, and misoperation is avoided.
