Abstract

An external supply system includes a sensing device to provide flush water automatically, and a supply device to provide cleaning liquid. The supply device is connected to the sensing device to provide the flush water and the cleaning liquid. Thus, the supply device co-operates with the sensing device to provide the cleaning agent and the flush water synchronously, thereby facilitating the user washing and cleaning the object.

Claims

1. An external supply system, comprising a sensing device to provide flush water automatically, and a supply device to provide cleaning liquid, wherein

the supply device is connected to the sensing device to provide the flush water and the cleaning liquid synchronously;

the supply device includes a body having an inside formed with a receiving chamber containing the cleaning liquid and having a bottom formed with a drop hole, and a press member movably mounted on the body to connect or disconnect the receiving chamber with the drop hole;

the body of the supply device has a lower portion provided with a cylinder having an inside formed with an operation space, the operation space of the cylinder has a first side communicating with the receiving chamber and a second side communicating with the drop hole of the body, and the press member of the supply device has a first end protruded outward from the body and a second end slidably mounted in the operation space of the cylinder;

the first side of the operation space of the cylinder communicates with the receiving chamber through the connecting hole of the receiving chamber;

the second side of the operation space of the cylinder is formed with a passage communicating with the drop hole of the body;

the second end of the press member has a diameter flush with that of the operation space of the cylinder;

the supply device further includes a sealing member mounted on the press member to move therewith and rested on a first side of the second end of the press member, so that the sealing member is driven by the press member to move between a first position where the sealing member closes and seals the drop hole of the body, thereby disconnecting the operation space of the cylinder with the drop hole of the body, and a second position where the sealing member is detached from the drop body, thereby connecting the operation space of the cylinder with the drop hole of the body;

the supply device further includes an elastic member mounted in the operation space of the cylinder and rested on the press member to press the press member to move the sealing member;

the elastic member of the supply device has a first end rested on a second side of the second end of the press member and a second end rested on a side of the operation space of the cylinder;

the receiving chamber of the body of the supply device has a bottom formed with a connecting hole communicating with the operation space of the cylinder, and the supply device further includes a stop ball movably mounted in the connecting hole of the receiving chamber of the body;

the body of the supply device has a top provided with a transparent cover to facilitate the user replenishing the cleaning agent; and

the sensing device has a first side provided with a water inlet and a second side provided with a water outlet.
