CROSS-TYPE PCB BOARD AND MASSAGE DEVICE WITH REPLACEABLE CASING

摘要

A cross-type PCB board and a massage device with a replaceable casing (4), comprising: a main board (1) and a secondary board (2). The main board (1) has at least one strip-shaped PCB board section, and the middle of the strip-shaped board section is provided with a fixing slot (11). In a combined state, the secondary board (2) is inserted into the fixing slot (11) and is then fixed to the main board (1) to form a PCB board structure having a cross-shaped cross section; at least four side faces of the cross-shaped PCB board structure are respectively provided with sensors for monitoring electromagnetic characteristics of external markers. The secondary board (2) is inserted into the fixing groove (11) and then fixed by means of an adhesive. The sensors are Hall sensors. The main board (1) further has a fixing section at a certain angle with respect to the strip-shaped PCB board section. A massage device with a replaceable casing (4), comprising a device body (3) and a casing (4) sleeved on the device body; the device body (3) comprises a shell and a control unit comprising a cross-type PCB board structure used for recognizing electromagnetic characteristics of a casing component; the casing (4) is in interference fit with the device body (3); a magnetic marker (43) having a specific marking characteristic is provided inside the casing (4).
