Part of toilet bowl for removing foul odor of excrement

Abstract

A toilet odor removing device is provided a valve including a spring biased plunger and a water chamber disposed around the plunger; an odor rejection and overflow assembly mounted downstream of the valve and communicating therewith; and a blower mounted downstream of the odor rejection and overflow assembly and communicating therewith. In response to an activation of the blower and sucking odor into the plunger, the plunger slides to increase a volume of the water chamber with the odor being prevented from passing through the odor rejection and overflow assembly.

1 . A device for removing odors from air in a toilet bowl environment, comprising:
 a valve comprising a spring biased plunger and a water chamber disposed around the plunger;   an odor rejection and overflow assembly mounted downstream of the valve and comprising a central passage communicating with the plunger; and   a blower mounted downstream of the odor rejection and overflow assembly and communicating with the odor rejection and overflow assembly;   wherein in response to an activation of the blower and sucking odor into the plunger, the plunger slides to increase a volume of the water chamber with the odor being prevented from passing through the odor rejection and overflow assembly.   
     
     
         2 . The device of  claim 1 , wherein the odor rejection and overflow assembly comprises the central passage being upstream of the blower, an annular trough mounted on the valve and communicating with the passage, and a hollow cylindrical member partially disposed in the trough. 
     
     
         3 . The device of  claim 2 , wherein the trough is divided into an inner region and an outer region by the cylindrical member. 
     
     
         4 . The device of  claim 3 , wherein an elevation difference between top of the trough and a water level of the inner region of the trough is about 0 mm to 30 mm. 
     
     
         5 . The device of  claim 3 , wherein an elevation difference between bottom of the cylindrical member and a water level of the inner region is about 5 mm to 50 mm. 
     
     
         6 . The device of  claim 3 , wherein a cross-section of water in the outer region is greater than 415 mm 2 . 
     
     
         7 . The device of  claim 2 , further comprising a supply line for supplying water to the trough. 
     
     
         8 . The device of  claim 1 , wherein the valve comprises the plunger having a central tunnel as an odor removal path, a rubber seal provided for sealing a joining portion of the plunger and a base, a support provided in the plunger and having a top above top of the plunger, a waterproof seal sealingly disposed between top of the support to the top of the plunger, an annular divider plate provided on an intermediate portion of a peripheral surface of the plunger, and a cylindrical outer frame provided on an outer edge of the divider plate to define an upper chamber in cooperation with the divider plate, an upper portion of the plunger, and an upper limit member. 
     
     
         9 . The device of  claim 8 , wherein the cylindrical outer frame further defines the water chamber in cooperation with the divider plate, a lower limit member provided on an intermediate portion of the plunger with the plunger slidably passing through, a portion of the plunger below the divider plate, and a lower portion of the outer frame, and further comprising a helical spring biased in the upper chamber. 
     
     
         10 . The device of  claim 9 , further comprising a drain on the lower limit member and opposite to an inlet of the water chamber. 
     
     
         11 . The device of  claim 10 , wherein the drain comprises a cup-shaped housing having a plurality of ports, a sliding sealing rubber, and a spring having one end anchored on an inner surface of the housing and the other end secured to the sealing rubber to block an outlet of the water chamber so that the sealing rubber slides to compress the spring to open the water chamber for exiting water. 
     
     
         12 . The device of  claim 11 , wherein the drain is operated automatically. 
     
     
         13 . The device of  claim 1 , further comprising an activated charcoal filter above the passage and the odor rejection and overflow assembly and a water suction prevention assembly. 
     
     
         14 . The device of  claim 13 , wherein the water suction prevention assembly comprises an upper block member including a plurality of port members, and a lower block member having a plurality of port elements communicating with the port members so that water components in the odor is prevented from sucking into the activated blower.
