Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air massage device that is excellent in safety for a user.
[0002]
[Prior art]
The air massage device is used by many users because it easily gives the user a pleasant feeling. In particular, a type of air massage apparatus having a plurality of air supply ports in one air compressor has recently become widespread. In this type of air massage device, one air supply port sends air to an air massage bag provided on a futon that uses high-pressure compressed air, and the other air supply port uses a human body that uses low-pressure compressed air. Air is sent to air massage bags provided on the legs, waist, and shoulders. Therefore, the user needs to select one of the air supply ports according to the state of use. However, if the air supply port is connected by mistake, High-pressure compressed air is supplied to the air massage bags such as the waist and shoulders. Thus, as a result of the supply of high-pressure compressed air to the foot, waist, and shoulders of the human body, these affected parts of the human body are compressed with an excessive pressure, causing unintentional harm to the human body. Such mounting errors are common among older people. However, conventionally, no measures have been taken to prevent such operation errors.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of the conventional drawbacks, and an object of the present invention is to enable anyone to distinguish between a high-pressure connection device and a low-pressure connection device at a glance and to have a different connection structure. Therefore, it is possible to prevent the low-pressure connector from being accidentally inserted into the high-pressure compressed air port, thus preventing the user from accidentally connecting the compressed air supply port for different pressures. The air massage bag body for low pressure can be configured as a cheaper bag body compared to the air massage bag body for high pressure and the air massage bag for low pressure. The object is to provide an air massage device that helps protect the body.
