The disclosure provides a neck massager including a main body, two clamping arms connected to two ends of the main body, respectively, and two clamping parts corresponding to the two clamping arms, respectively. The two clamping parts are rotatably disposed on the two clamping arms, respectively; the two clamping parts are disposed opposite to each other to clamp a user's neck; each clamping arm includes a first rotating axis, and each clamping part is rotatable around the first rotating axis; each clamping part includes at least a first end and a second end that are different in distance from the first rotating axis; each clamping part includes a circumferential side surrounding the first rotating axis; and the first end and the second end are respectively disposed at two ends of the circumferential side of each clamping part.

A dustproof nasal irrigator includes a nozzle assembly and a shielding cover. The nozzle assembly includes a nozzle seat, a raw liquid nozzle and a waste liquid nozzle, the raw liquid nozzle and the waste liquid nozzle are both connected to the nozzle seat, the shielding cover is detachably connected to the nozzle seat, a receiving cavity is provided in the shielding cover, and when the shielding cover is connected to the nozzle seat, the raw liquid nozzle and the waste liquid nozzle are both located in the receiving cavity.

A physical therapy appliance includes a shell wherein inside the shell is provided an accommodating cavity; a soft colloid wherein the soft colloid is provided a massage channel, and at an end portion of the soft colloid is provided an opening of the massage channel; pressure expansion portions wherein the pressure expansion portions are provided on the soft colloid; and a pressure generating mechanism configured to adjust pressure of the pressure expansion portions. Expansion of pressure expansion portions enables the massage channel of the soft collide to extrude, thereby working out a penis and getting an erection last longer; the pressure generating mechanism adjusts pressure of the pressure expansion portions, so as to freely control pressure of the soft colloid, and enable the massage channel of the soft collide to exert different extruding forces, so the massage channel of the soft collide can be adapted to different specifications of penises.
