Description

Technical Field

[0001] The utility model relates to the technical field of health care equipment, in particular to a waterproof reduction motor. Background Art

[0002] Currently commonly used massage sticks generally include telescopic and vibration functions. The telescopic structure that realizes the telescopic function and the vibrator that realizes the vibration function are generally driven by the same motor. The rotation of the motor itself can directly drive the telescopic structure to rotate and extend, and a reducer will be installed between the motor and the telescopic structure.

[0003] Conventional massagers typically incorporate a connecting housing between the reducer and the telescopic mechanism. The reducer's rotating shaft passes directly through the connecting housing and connects to the telescopic mechanism. This creates a gap between the connecting housing and the telescopic outer cylinder of the telescopic mechanism, and the connecting housing of these massagers lacks a waterproof structure. During use, due to the gap between the connecting housing and the telescopic outer cylinder, water can enter the connecting housing through the gap and then into the reducer, causing rust and damage to the reducer's internal components. This compromises the waterproofing and shortens its service life. Utility Model Content
