Description

Massage device {MASSAGE DEVICE}

The present invention relates to a massage device, and more specifically, to monitor obstacles inserted into a space between a massage body and a massage unit in the process of massaging the user's body while holding and moving the user's hand, It relates to a massage device for controlling rotation of a massage unit when an obstacle is inserted into a space.

In general, a massage device is mainly used to release muscles and treat body pain through a pressing or tapping action on a body part such as a back, arm, or leg. Massage devices are manufactured and sold in a variety of shapes and sizes according to body parts to be used.

Currently, massage devices that are widely sold include a backrest type massage device that can be attached to a chair to intensively massage the back, a chair type massage device that is made in the form of a chair on which a user can sit, and a user holding a handle and the like. A portable massage device capable of massaging a desired body part is a typical example.

The backrest type massage device combines a vibration force transmission body with an eccentric shaft of a motor, and when used, the vibration force transmission body vibrates at a certain position and is configured to massage only the back or waist part intensively. Therefore, it is difficult for a user to massage a body part other than the back or waist. It is also bulky and inconvenient to transport or store.

A chair-type massage device can massage various body parts of a user, but has disadvantages in that it is expensive and takes up a lot of installation space.

Although the portable massage device has the advantage of being small in volume and convenient to use, the conventional portable massage device has a disadvantage in that the massaging effect on the body part is poor. In addition, when an obstacle such as a part of the user's body or the user's clothing is inserted between the massage body and the massage unit, a safety accident occurs in which the part of the user's body is damaged or the user's clothing and the massage unit are entangled and the massage device is damaged there was a problem with
