1. A detection device, comprising:
a housing (10), a wall detection assembly (20) and a multimeter assembly (30), wherein
the wall detection assembly (20) comprises a sensing assembly (202) and a wall detection processing circuit (201), the sensing assembly (202) and the wall detection processing circuit (201) being both arranged inside the housing (10); and the sensing assembly (202) being electrically connected to the wall detection processing circuit (201), and the sensing assembly (202) comprising at least one of a metal detection sensing element (202a), a foreign object detection sensing element (202b) and an alternating-current voltage signal sensing element (202c);
wherein the sensing assembly (202) and the wall detection processing circuit (201) are arranged spaced apart in a first direction, and the sensing assembly (202) and the multimeter assembly (30) are arranged staggered in a second direction, the first direction and the second direction forming an included angle; and the sensing assembly (202) is mounted to an inner side wall of the housing (10) via a connection structure (60),
wherein
the housing (10) comprises a top housing (101) and a bottom housing (102) that are snap-fitted with respect to each other in the first direction, and the multimeter assembly (30) further comprises a multimeter measurement circuit (301) arranged inside the housing (10); and
the wall detection processing circuit (201) and the multimeter measurement circuit (301) are arranged on the same plane which is arranged closer to the top housing (101) than to the bottom housing (102), and the sensing assembly (202) is mounted to an inner side wall of the bottom housing (102) via the connection structure (60),
wherein
the sensing assembly (202) comprises the metal detection sensing element (202a), and the metal detection sensing element (202a) is detachably snapped to the inner side wall of the bottom housing (102) via the connection structure (60).
