[0002] The electric energy metering box is a device for measuring and metering electric energy consumption, which is widely used in power supply and power management systems. The electric energy metering box can provide accurate electric energy metering and monitoring functions, which helps to monitor the electric energy use in real time.

[0003] At present, the general electric energy metering box is provided with a heat dissipation hole and an exhaust device to accelerate the air flow in the metering box, so as to avoid internal circuit short circuit and cause damage to the electric energy metering box, and even cause fire and other situations.

[0004] However, when the electric energy metering box is set outdoors, the air humidity increases significantly when severe rainfall and other bad weather occurs, which causes the circuit, components and other components in the electric energy metering box to be prone to short circuit. SUMMARY

[0005] In order to improve the safety of the electric energy metering box, the present application provides an electric energy metering box.
