Vapor recovery and water collection box structure of heating barrel

Abstract

A vapor recovery and water collection box structure of a heating barrel includes a vapor box, a heating barrel unit, and a faucet. The faucet includes an outer tube and an inner tube. Vapor is guided into the vapor box and out from the inner tube of the faucet, preventing the accumulation of the vapor from generating biogas and preventing the outer tube from generating heat. Through the vapor box to recycle the condensed water, the heating barrel is safe for use and able to prevent leaks.

What is claimed is: 
     
         1 . A vapor recovery and water collection box structure of a heating barrel, comprising:
 a vapor box, the vapor box including an upper box lid and a lower box tray, the upper box lid having a first guide opening, a second guide opening, and an air inlet, the first guide opening being fixedly connected with a backflow connecting tube, the second guide opening being fixedly connected with a check valve connecting tube, the air inlet being provided with a non-return air inlet valve, the upper box lid and the lower box tray being sealed against each other to form an accommodation chamber therebetween, the accommodation chamber being provided with a water collection trough and a float ball seat above the water collection trough, the float ball seat having a plurality of float ball limit grooves defined therein, a bottom side of each float ball limit groove being formed with a guide hole, a float ball being provided above the guide hole, the float ball being able to float and displace relative to a corresponding one of the float ball limit grooves.   
     
     
         2 . The vapor recovery and water collection box structure of a heating barrel as claimed in  claim 1 , wherein an inner side of the guide hole is provided with a check ring, wherein when the float ball in the corresponding float ball limit groove descends, the float ball is to abut against the check ring. 
     
     
         3 . A vapor recovery and water collection box structure of a heating barrel, comprising:
 a vapor box, the vapor box including an upper box lid and a lower box tray, the upper box lid having a first guide opening, a second guide opening, and an air inlet, the first guide opening being fixedly connected with a backflow connecting tube, the second guide opening being fixedly connected with a check valve connecting tube, the air inlet being provided with a non-return air inlet valve, the upper box lid and the lower box tray being sealed against each other to form an accommodation chamber therebetween, the accommodation chamber being provided with a water collection trough and a float ball seat above the water collection trough, the float ball seat having a plurality of float ball limit grooves defined therein, a bottom side of each float ball limit groove being formed with a guide hole, a float ball being provided above the guide hole, the float ball being able to float and displace relative to a corresponding one of the float ball limit grooves.   a heating barrel unit, the heating barrel unit including a barrel body, a top side of the barrel body being provided with a water inlet duct and a water outlet duct, the barrel body being provided with a heating controller disposed close to a bottom edge thereof, a side of the water inlet duct being provided with a recovered water guide mouth, the water inlet duct being provided with a water inlet tube extending into the barrel body close to a bottom of the barrel body, a side of the water outlet duct being provided with a vapor guide mouth, the vapor box being fixedly disposed on top of the heating barrel unit, the backflow connecting tube of the first guide opening of the vapor box being connected to the recovered water guide mouth of the water inlet duct, the check valve connecting tube of the second guide opening being connected to the vapor guide mouth of the water outlet duct; and   a faucet, the faucet including an outer tube and an inner tube in the outer tube, the inner tube being connected with the water outlet duct of the heating barrel unit.   
     
     
         4 . The vapor recovery and water collection box structure of a heating barrel as claimed in  claim 3 , wherein an inner side of the guide hole is provided with a check ring, wherein when the float ball in the corresponding float ball limit groove descends, the float ball is to abut against the check ring.
