Pre-embedded base device

Abstract

A pre-embedded base device includes a pre-embedded base, a first plug detachably coupled to the pre-embedded base, and second plug detachably coupled to the first plug. The pre-embedded base defines a base water chamber and a water inlet channel in communication with the base water chamber. The first plug has a drainage channel in communication with the base water chamber and a water pipe joint in communication with the drainage channel. When the pre-embedded base device is in an initial configuration, the first plug is coupled to the pre-embedded base, the second plug is coupled to the first plug, the first plug seals the base water chamber, and the second plug seals at least one of the drainage channel or the water pipe joint.

         1 . A pre-embedded base device comprising:
 a pre-embedded base;   a first plug detachably coupled to the pre-embedded base; and   a second plug detachably coupled to the first plug;   wherein the pre-embedded base defines a base water chamber and a water inlet channel in communication with the base water chamber;   wherein the first plug has a drainage channel in communication with the base water chamber and a water pipe joint in communication with the drainage channel; and   wherein when the pre-embedded base device is in an initial configuration, the first plug is coupled to the pre-embedded base, the second plug is coupled to the first plug, the first plug seals the base water chamber, and the second plug seals at least one of the drainage channel or the water pipe joint.   
     
     
         2 . The pre-embedded base device according to  claim 1 , wherein:
 the pre-embedded base device comprises a protective cover detachably coupled to the pre-embedded base; and   when the pre-embedded base device is in an initial state, both the first plug and the second plug are located within the protective cover.   
     
     
         3 . The pre-embedded base device according to  claim 2 , wherein the protective cover comprises:
 a cover cylinder detachably coupled to the pre-embedded base; and   a cover cap detachably coupled to the cover cylinder.   
     
     
         4 . The pre-embedded base device according to  claim 3 , wherein the cover cylinder is provided with at least one cutting position marking. 
     
     
         5 . The pre-embedded base device according to  claim 1 , wherein:
 the first plug comprises:
 a plug body defining the drainage channel, and 
 a plug lug plate coupled around the plug body; 
   the water pipe joint is coupled at a top of the plug body and is arranged coaxially with the drainage channel;   the plug lug plate rests on a top of the pre-embedded base and is coupled to the pre-embedded base by a connection member; and   the plug body is inserted in the base water chamber and seals against a cavity wall of the base water chamber.   
     
     
         6 . The pre-embedded base device according to  claim 5 , wherein a circumferential surface of the plug body includes at least one a first sealing ring configured to seal against the cavity wall of the base water chamber. 
     
     
         7 . The pre-embedded base device according to  claim 5 , wherein:
 the second plug comprises:
 a plug end cap, and 
 a plug rod body coupled to the plug end cap; 
   the plug rod body is inserted in the water pipe joint and the drainage channel and seals at least one of the water pipe joint or the drainage channel; and   the plug end cap is positioned above the water pipe joint.   
     
     
         8 . The pre-embedded base device according to  claim 7 , wherein a circumferential surface of the plug rod body includes at least one a second seal ring configured to seal at least one of the water pipe joint or the drainage channel. 
     
     
         9 . The pre-embedded base device according to  claim 7 , wherein:
 an inner surface of the water pipe joint is provided with an internal thread;   an outer surface of the water pipe joint is provided with an external thread; and   an upper end of the plug rod body has a threaded connection segment, the threaded connection segment configured to engage the internal thread of the water pipe joint to detachably couple the plug rod body to the water pipe joint.   
     
     
         10 . The pre-embedded base device according to  claim 9 , wherein the external thread of the water pipe joint is configured engage a thread of a drainage pipe to detachably couple the drainage pipe to the water pipe joint. 
     
     
         11 . The pre-embedded base device according to  claim 7 , wherein the plug end cap is provided with an end cap recess configured to interface with a tool.
