Preferably, as shown in fig. 1, the relief valve 2 includes a valve cover 21 and a valve spool 22; as shown in fig. 1 or 4, one end of the valve core 22 is open and integrally formed by using an elastic material for food contact, specifically, the material is a silica gel for food contact, and the silica gel comprises a head part 221 and a support part 222, wherein the head part 221 seals the pressure relief hole 12; as shown in fig. 2 or 3, the bottom surface of the valve cover 21 is provided with a mounting column 211 and a threaded column 212 from inside to outside; the valve core 22 is sleeved on the mounting column 211 through a support part 222, and a gap is formed between the mounting column 211 and the head part 221; the threaded column 212 is provided with external threads which are matched with the internal threads on the mounting part 11; a gap is provided between the valve cover 21 and the mounting portion 11 for pressure relief.

Preferably, as shown in fig. 4, the outer wall or the inner wall of the supporting portion 222 is provided with outer annular grooves and inner annular grooves at intervals, and the outer annular grooves and the inner annular grooves are arranged alternately; this structure can increase the elasticity of the support portion 222.

Preferably, as shown in fig. 4, the head 221 is a convex cone, and the conical surface can increase the contact area of the gas, so as to facilitate the air pressure jacking the valve core 22 to open the pressure relief hole 12 for air exhaust and pressure relief, and can also enhance the sealing performance of the pressure relief hole 12 to avoid water leakage from the position.

Preferably, as shown in fig. 2 or 3, the bottom surface of the mounting portion 11 is located at the periphery of the pressure relief hole 12 and is bent inward, so that an air guide groove is formed below the mounting portion and a contact inclined surface matched with the tapered surface of the head portion 221 is formed above the mounting portion. With the structure, the air guide groove can collect more air, so that the pressure of the head part 221 is higher, the valve core 22 is more easily jacked open, and the air pressure in the cup is lower; the contact inclined plane is matched with the conical surface of the head part 221, so that the contact area of sealing is increased, and the sealing performance is better.
