2, the residual agent monitoring apparatus 100 includes a housing 110, an elastic body guide 120, an elastic body 130, a magnetic bar 140, a sensor 150, a ringer rest 160, a controller 170 ).

The housing 110 serves as a case for mounting a plurality of modules therein, and may be provided in various shapes in addition to design elements such as a polyhedral shape.

The elastic guide 120 may be attached to one side of the upper end of the housing 110 and may have a hole therein. An elastic body 130 is provided in the inner hole of the elastic guide 120 and one end of the elastic body 130 may be fixed to the inner wall of the elastic guide 120.

The magnetic bar 140 may be connected to one end of the elastic body in an opposite direction to the inner wall of the inner hole of the elastic body guide 120. The longitudinal direction of the magnetic bar 140 and the longitudinal direction of the elastic body 130 may be They can be joined at right angles.

The sensor 150 may be spaced a predetermined distance from the magnetic bar 140. In this case, the sensor may be at least one of a Hall sensor, an infrared sensor, an ultrasonic sensor, and a laser sensor. When a Hall sensor is used, the Hall sensor may be used to measure the magnetic force of the magnetic bar 140 Can be measured.

The ringer cradle 160 may be formed in a bar shape, which is positioned between the magnetic bar and the sensor and has a rotation axis at a central portion thereof.

That is, when the remaining amount of the Ringer's fluid is relatively large as shown in FIG. 2 (a), the rotation angle of the Ringer's cradle 160 increases due to the weight of the Ringer's, The weight of the ringer is relatively light, and the rotation angle of the ringer holder 160 is reduced. That is, as the rotation angle of the ringer rest 160 is increased, the magnetic bar 140 is pushed more and the intensity of the magnetic field sensed by the sensor 150 is weakened.
