Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The installation and use operation process comprises the following steps: after installing the valve core rod 4 sleeved with the silica gel plug 5 into the hole of the drain valve shell 3, buckling the rear cover 6 to the outermost end of the drain valve shell 3, adopting fastening sealing at the matching part of the rear cover 6 and the drain valve shell 3, and then sleeving the sealing ring 2 on the other end of the drain valve shell 3 and then integrally installing the sealing ring at the drain port designed in the main body groove 1; after the rack 7 is installed on an installation plane on the outer side of the main body groove 1, the pressing plate 8 is installed and matched on the rack 7, the rack 7 and the pressing plate 8 are integrally fastened in place, the travel switch plate 9 is installed in the clamping groove of the pressing plate 8, two U-shaped induction areas with a certain distance are arranged on the travel switch plate 9, the rack 7 is provided with an induction area 711, and the travel switch plate 9 comprises a plug-in terminal and is connected with the control assembly 13 in a wiring mode to realize program control; the rack 7 and the valve core rod 4 are connected and fastened in place through screws; the supporting seat 12 is installed and fastened on the main body groove 1, the gear 10 is installed and matched on the rotating shaft of the motor 11, finally, the motor 11 provided with the gear 10 is installed on the semicircular groove of the supporting seat 12 and then is fastened in place through screws, and the gear 10 is just meshed with the rack 7.

When the drainage process is started, the motor 11 rotates forwards, the gear 10 rotates forwards through the meshing relation between the gear 10 and the rack 7, the rack 7 is driven to pull the valve core rod 4 and the silica gel plug 5 backwards, the drainage port is gradually opened, and the drainage process is started. When the induction area 711 on the rack 7 moves to the far-end U-shaped induction area 912 of the travel switch plate 9, the control program receives a signal, the motor 11 stops rotating, at the moment, the silica gel plug 5 moves backwards to the maximum distance, and the drainage valve is opened to the maximum for drainage; after the preset time of water drainage, the control program automatically gives a signal to the motor 11 to enable the motor 11 to reversely rotate, the rack 7 and the valve core rod 4 are gradually returned to the original positions, and after the induction area 711 on the rack 7 returns to move to the near-end U-shaped induction area 911 of the travel switch plate 9, the motor 11 obtains a closing signal, stops rotating and closes the drainage valve.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
