  By the way, in the above-mentioned air massage machine, there is a tendency to use an air pump having a large air pressure and flow rate in order to meet the needs of users in recent years, and accordingly, vibration generated by driving the air pump has increased. It was. Since the air pump and the switching device are linearly connected by the flexible hose, the transverse component (hose radial direction component) of the flexible hose can be sufficiently absorbed in the vibration from the air pump. The vertical component (hose extending direction component) propagates to the switching device via the hose, and so-called chatter noise may be generated by propagating from the switching device to the housing.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an air massage machine that suppresses propagation of vibration of an air pump to a housing and has high silence.

  In order to solve the above-mentioned problems, the invention according to claim 1 is arranged to be connected to the air pump to suppress air supply / exhaust noise and to be rigidly connected to the air pump. A silencer and a control member connected to the silencer and controlling air supply / exhaust from the air pump are provided in the housing, and an air bag connected to the control member is provided by air supply / exhaust by the air pump. An air massage machine for inflating and contracting to treat a user, wherein a flexible first connected to the first hose connection port of the silencer to connect the silencer and the control member. The gist is that the hose and the flexible second hose connected to the second hose connection port of the control member are jointed by the joint member so as to intersect. That.

  In this invention, in order to connect a silencer and a control member, the flexible 1st hose connected to the 1st hose connection port of a silencer, and the possibility connected to the 2nd hose connection port of a control member The joint members are connected to each other so that the second hose having flexibility intersects. Thereby, the longitudinal component and the transverse component are generated by the flexible first and second hoses jointed so that the vibrations generated by the driving of the air pump and propagated through the silencer intersect. Each of these vibrations can be suitably suppressed.

The gist of the invention described in claim 2 is that the first hose and the second hose are jointed in an L shape.
In the present invention, since the first hose and the second hose are jointed in an L shape, that is, in an orthogonal direction, vibration can be more suitably suppressed.

  According to a third aspect of the present invention, in the air massage machine according to the first or second aspect, the first hose connection port of the silencer is the control member, and the second hose connection port of the control member is the silencer. The gist is that it is set to a mode that is not suitable for each.

  In the present invention, the first hose connection port of the silencer is set to the control member, and the second hose connection port of the control member is set not to face the silencer. Thereby, compared with the case where the 1st hose connection port and the 2nd hose connection port are made to oppose, it becomes possible to make easy handling of the 1st hose and the 2nd hose provided in the mode which intersects.

  According to a fourth aspect of the present invention, in the air massage machine according to the third aspect, the first hose connection port of the silencer and the second hose connection port of the control member are directed in the same direction. The gist.

  In this invention, the 1st hose connection port of a silencer and the 2nd hose connection port of the said control member are orient | assigned to the same direction. Thereby, it becomes possible to attach a 1st hose and a 2nd hose easily. Moreover, a 1st hose and a 2nd hose can be comprised short, and it can contribute to the space saving of the whole air massage machine.

  According to a fifth aspect of the present invention, in the air massage machine according to any one of the first to fourth aspects, the joint member is configured to be more rigid than the first and second hoses. Is the gist.

  In this invention, the joint member is configured to be more rigid than the first and second hoses. That is, it is possible to reliably maintain the intersecting state of the first hose and the second hose so that the vibration can be suitably suppressed by the joint member having higher rigidity than the first hose and the second hose.

  ADVANTAGE OF THE INVENTION According to this invention, propagation of the vibration of an air pump to the housing can be suppressed and an air massage machine with high silence can be provided.
