The invention relates to an underwater sealed cabin, and underwater equipment with electronic components. The underwater sealed cabin comprises a shell, a sealed space is formed in the shell, a vent hole for communicating the outside with the sealed space is formed in the shell, a first one-way valve is arranged at the ventilation hole, and the first one-way valve is opened when the air pressure in the sealed space is larger than a preset value; and a waterproof ventilation valve is arranged at the end, connected with the sealed space, of the first one-way valve. According to the underwater sealed cabin, the ventilation hole is formed in the shell, the waterproof ventilation valve is arranged at the ventilation hole, the first one-way valve is arranged on the outer side of the waterproof ventilation valve, the first one-way valve can protect the waterproof ventilation valve when the external water pressure is large, and the waterproof ventilation valve is prevented from being damaged due to the too large water pressure. Meanwhile, when the pressure in the sealed space in the shell is low and negative pressure is formed, the first one-way valve can protect the waterproof ventilation valve, the waterproof ventilation valve is prevented from being damaged due to external water pressure, and the sealed space in the underwater sealed cabin can be maintained, so that external water can not enter the sealed space.

    本发明涉及一种水下密封舱及具有电子元件的水下设备。水下密封舱包括壳体,壳体内具有密封空间,壳体上设置有将外界与密封空间连通的通气孔,通气孔处设置有第一单向阀,第一单向阀在密封空间内的气压大于设定值时开启;第一单向阀与密封空间相接的一端设置有防水透气阀。上述水下密封舱,壳体上具有通气孔,在通气孔处设有防水透气阀,且在防水透气阀的外侧设有第一单向阀,该第一单向阀可在外部水压较大时保护防水透气阀,避免防水透气阀因过大的水压压力而损坏。同时,在壳体内的密封空间内的压力较低,形成负压时,第一单向阀可保护防水透气阀,避免防水透气阀因外界水压而损坏,使水下密封舱内的密封空间能够维持而不被外界的水进入。
