The present invention relates to a pneumatic distributor, and in particular, at least one, for example, by adsorbing the skin to obtain the effect of cupping that promotes blood circulation, such as a cupping device, opens and closes the pipe connected to the applicator of the skin care device for skin health It relates to a pneumatic distributor of an improved structure to indicate the applicator in communication with the hole of the rotation shaft by providing a hall sensor to correspond to the position of the hole provided on the rotation shaft conveniently without using a solenoid to do so.

In general, a pneumatic distributor is widely used in various industries to allow the suction force of the motor to communicate with any one selected from among a plurality of applicators, or to selectively supply compressed air of the motor to the applicators.

Such a pneumatic distributor is used to distribute compressed air generated by a motor to a plurality of applicators or to apply negative pressure of a vacuum generated by a motor to a plurality of applicators.

As an example of such a pneumatic distributor, Korean Patent Registration No. 10-1541605 (published on Aug. 03, 2015) discloses an outer tube having an inlet hole formed on the upper outer periphery in the longitudinal direction, and a movable piston inserted into the outer tube. A cannula comprising an inner tube that reciprocates forward and backward together with movement and a suction hole is formed on the upper periphery to suck fat; a connecting tube connected to the lower end of the outer tube and having a moving space therein; a moving piston connected to the lower end of the inner tube and reciprocating within the connecting tube; an operation rod connected to the lower end of the moving piston, a suction passage communicating with the inner tube formed therein, and being drawn in and out of the operation member; an operation member connected to the lower end of the connection pipe and reciprocating the operation rod; and a discharge pipe connected to the lower end of the working rod, formed to communicate with the suction path, and the lower end connected to the suction hose of the vacuum inhaler to discharge the sucked fat.

This liposuction device generates a vacuum negative pressure by a motor and uses the vacuum negative pressure to suck and remove fat accumulated in the body, and the generated vacuum negative pressure is selectively connected from among a plurality of cannulas connected to the distributor, The conduits connecting the cannula are configured to communicate in series through the solenoid valves, and in order to open the last conduit, the configuration becomes complicated in that all the preceding solenoid valves must be opened, resulting in an increase in the manufacturing cost of the vacuum suction device, There was a problem in that frequent failures occurred due to unnecessary current supply to several electrically operated solenoid valves.
