Electric appliance box and device with same

Abstract

The invention provides an electric appliance box and a device with the electric appliance box. The electric appliance box comprises a box body which is provided with an accommodating cavity suitable for accommodating a circuit board, the box body is provided with at least one wire outlet communicated with the accommodating cavity, and the wire outlet is suitable for leading out a wire connected with the circuit board; The at least one blocking rib is arranged corresponding to the wire outlet, extends out of the first opening wall of the wire outlet in the direction far away from the wire outlet, and extends towards a second opening wall opposite to the first opening wall; And the projection of the blocking rib on the side wall of the box body where the wire outlet is located covers the wire outlet. On one hand, a wire connected with the circuit board can be led out through a gap between the blocking rib and the wire outlet, and on the other hand, when fire breaks out in the electric appliance box due to circuit board faults, flames jumping out of the wire outlet can be blocked by the blocking rib and cannot directly jump out of the electric appliance box through the wire outlet, sothat the safety of the electric appliance box can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to an electrical appliance box and a device with the appliance box. Background technique [0002] Air purifiers are generally designed with an electrical box for placing circuit boards. Its primary function is to block the flame to a certain extent when the circuit board fails and burns. The side wall of the electrical box is usually designed with an outlet hole for drawing out the wiring connected to the circuit board. However, the outlet hole on the existing electrical box is generally a gap that is simply opened on the side wall of the electrical box. As a result, when the circuit board fails and catches fire, the flame can easily escape from the outlet hole, and it is impossible to protect the inside of the electrical box. Effectively block the flame generated when the circuit board fails. Contents of the invention [0003] Therefore, the technical p...
