INLET DEVICE FOR CENTRAL VACUUM SYSTEM

摘要

The present invention consists of an inlet device, of the valve type, used in a Central Vacuum System (CVS) and built into the skirting board, namely in the kitchen of a house. The function of the device is to collect dust and small debris with the aid of a broom into the entrance of this CVS, by means of a micro-switch activated CVS mechanism located in the skirting board, so as to avoid the use of a vacuum cleaner or vacuum tube also connected to the CVS. The device comprises: a base body (1) which can be assembled on the wall at the height of the skirting board; a cover (2) which engages in the base body (1); an unlocking button (3) which disengages the cover (2); a sealing strip (4) which is glued to the base body (1); a micro-switch (5) which engages in the base body (1); a helical torsion spring (6) engaged in the cover (2), by means of a pin, which causes the cover (2) to open in relation to the base body (1). By pressing the unlocking button (3) the user causes the opening of the cover, which activates the micro-switch (5), which, in turn conveys an electric signal to the CVS so that it starts to vacuum.
