[0002] Rubber hoses are generally used to transport petrochemical products, natural gas, combustible gases, high-temperature and high-pressure media, etc. During the transportation process, as the medium flows, it will rub against the inner surface of the rubber hose, generating static electricity, which will then be distributed on the outer surface of the rubber hose. The storage of static electricity can easily induce a fire, so it is necessary to treat the rubber hose with anti-static measures.

[0003] A previously published patent (publication number CN201748053U) discloses an antistatic suction hose, comprising, from the inside out, an inner rubber layer, a first canvas layer, a middle rubber layer, a second canvas layer, and an outer rubber layer. The hose also includes a steel wire and a conductor. The steel wire is disposed within the middle rubber layer, and the conductor is entirely attached to the steel wire and exposed at both ends of the hose. In this utility model, the suction hose uses a conductor to connect the conductor to the steel wire skeleton throughout the hose body, with the conductor exposed at both ends of the hose opening. As long as any point on the conductor outside the hose is grounded, the static electricity generated by the transported medium can be conducted away, avoiding the risk of fire due to static electricity and increasing safety.
