Abstract: Provided a vibrating spear, including a first body, a second body, and a turning assembly. The second body is provided with a sliding groove in a thickness direction thereof. The first body and the second body are rotationally connected. The turning assembly includes a motor and an eccentric part. One end of the eccentric part stretches into the sliding groove. A second connecting portion is provided with a first stopping surface and a second stopping surface that stop the eccentric part at an opening of the sliding groove, and an included angle between the first stopping surface and the second stopping surface is 25-35°, which limits the moving range of the eccentric part in the sliding groove. Thus, the turning amplitude of a hooking portion is controlled, and the problem that the vibrating spear excessively extrudes a clitoris or is insufficient in strength in a hooking process is avoided.

Abstract: The present application provides a pulse penis, including a shell, a first pulse assembly, and a second pulse assembly. The first pulse assembly includes a first motor arranged in an accommodating cavity. The second pulse assembly includes a second motor arranged in the accommodating cavity. The second motor is arranged behind the first motor in a length direction of the shell. An axis of the first motor and an axis of the second motor are located on a same straight line in the length direction of the shell, and the first motor and the second motor operate alternately. The pulse penis generates continuous pulse vibrations with percussive changes in the length direction of the shell as the coaxial double motors operate alternately. This pulse effect can effectively simulate the natural rhythm in a true physiological response.

Abstract: The present application provides a masturbator. The masturbator is provided with a shell, including a handle and a first stimulating head movably connected to the handle. The first stimulating head includes a main body and a first stimulating surface arranged on the main body. A first boss is arranged on the first stimulating surface, and one side of the first boss facing away from the first stimulating surface is provided with a third surface; and a first heating film covers the third surface. According to the masturbator, as the boss is arranged on the stimulating surface and the heating film only covers the third surface, heat is centralized in a region where a stimulating effect is most centralized, the heating efficiency is greatly improved, and the endurance of the device is improved.

Abstract: A hair treatment device includes a main body and a housing. The main body includes a tool bit device. The housing includes an accommodating cavity. The tool bit device is movably accommodated in the accommodating cavity in a telescopic manner. When the tool bit device is accommodated in the accommodating cavity, the tool bit device is automatically turned off; and when the tool bit device extends out of the accommodating cavity, the tool bit device is automatically turned on. According to the hair treatment device of the present disclosure, the tool bit device is movably accommodated in the accommodating cavity in the telescopic manner, so that the tool bit device is effectively protected. Meanwhile, the tool bit device is disposed to be automatically turned on or turned off, which is not required to manually operate a control switch to control an on-and-off state of the tool bit device.
