It is designed to be mounted to a mounting plate 11 of a household lift, providing electric control for the lift. The electrical protection box includes an electrical protection box base 1 and a removably fixed electrical protection box cover 3, which together form a sealed electrical protection box with a cavity. The electrical protection box has multiple openings that provide passageways for power cables, connecting wires, and other wiring connected to the components within the box, as well as connections to external components to achieve electrical control pathways.

[0029] Specifically, the electrical protection box cover 3 is an integrally formed structure with an L-shaped cross-section, consisting of a front facade 32 and an upper top surface 34 integrally connected thereto, wherein, in the installed state, the front facade 32 faces the room, and the upper top surface 34 is parallel to the lower bottom surface 124 of the electrical protection box base 1, which will be described in detail below. The electrical protection box base 1 includes the lower bottom surface 124, a left facade 115 and a right facade 110 of equal height arranged on opposite sides of the lower bottom surface 124 and extending vertically upward, and a rear facade 114 connected to the lower bottom surface 124 at the bottom and connected to the left facade 115 and the right facade 110 on the corresponding sides on opposite sides. When the electrical protection box cover 3 is in a state of being buckled with the base of the electrical protection box 1, the front facade 32 is parallel to the rear facade 114, forming the four walls of the electrical protection box, and the upper top surface 34 is used to close the upper end opening, so that the electrical protection box is closed. Optimally, fixing ears 111 with base rear fixing holes 123 are integrally formed on the outwardly facing surfaces of the left and right facades 115 and 110. Correspondingly, cover plate fixing ears 31 corresponding to the positions of the fixing ears 111 are provided on opposite sides of the upper top surface 34. The cover plate rear fixing holes 33 of the cover plate fixing ears correspond to the base rear fixing holes 123 of the fixing ears. The fixing piece passes through the two fixing holes to secure the upper top surface 34. The front facade 32 is provided with a cover plate front fixing hole 4. The electrical protection box base 1 is integrally formed with a fixing portion with a base front mounting hole 118 facing inward. In the engaged state, the base front fixing hole 118 corresponds to the cover plate front fixing hole 4. The fixing screws 2 are sequentially inserted through the cover plate front fixing hole 4 and the base front fixing hole 118 from front to back, completing the fixed connection between the electrical protection box cover 3 and the electrical protection box base 1. When disassembly is required, the fixing screws 2 are loosened from the front of the electrical protection box, that is, the side surface facing the room, to remove the electrical protection box cover 3, which is easy to disassemble and easy to maintain.
