Toilet bowl with changeable water seal

Abstract

The present invention relates to a toilet bowl with a changeable water seal, which comprises an upper region, a waste drain outlet of the upper region, a lower region and a waste drain outlet of the lower region. A deviated waste discharge passage is fixed on a supporting shaft or a supporting bore. A reposition apparatus is arranged for the reposition of the waste discharged passage, the lower end of which surrounds the waste drain outlet of the upper region, the higher end of which could be depressed and repositioned automatically and be lead to the waste drain outlet of the lower region. This invention could overcome these disadvantages that immobile waste discharge passage of the traditional toilet bowl between the waste drain outlet of the upper region and the waste drain outlet of the lower region has a higher water seal, a higher water resistance and higher water consume. The waste discharge passage of this invention is deviated automatically to form a lower water seal while flushing, and is repositioned automatically to form a higher water seal while non-flushing. It can not only seal the dour but also improve the flushing efficiency and save water. The structure of invention is simple and reliable and has lower cost.

1 . A variable water sealed toilet bowl, comprising: an upper chamber, a lower chamber, an upper chamber outlet and a lower chamber outlet; wherein a tiltable sewage draining passage is provided which is mounted on a supporting axle or supporting hole, wherein a lower end thereof surrounds the upper chamber outlet, and a higher end thereof capable of descending and resetting automatically leads to the lower chamber outlet, and a reset device for the tiltable sewage draining passage is also provided.  
   
   
       2 . The variable water sealed toilet bowl according to  claim 1 , wherein the described tiltable sewage draining passage is tubular, namely, the configuration of the tiltable tubular sewage draining passage is: a flexible tubular sewage draining passage is mounted on the outside groove of the elbowed upper chamber outlet, the tiltable frame tilting around the axle is supported in the supporting hole on the hoop supporter fastened with bolt, and there is a reset device on one side of the tiltable frame, the other side thereof inclines to extend upwards to join the flexible tubular sewage draining passage that is extending with it simultaneously or join the tubular sewage draining passage connected to the flexible tubular sewage draining passage to form a horizontal, vertical or inclined tiltable outlet leading to the lower chamber outlet, and is tilted and reset with the tiltable frame synchronously; there is a narrow plate in the middle of the frame edge on one side of the tiltable frame, that bends downwards to form a bump, the narrow plate bending downwards and the bump form the limit plate and limit bump limiting tilt and reset.  
   
   
       3 . The variable water sealed toilet bowl according to  claim 1 , wherein the described tiltable sewage draining passage is basin-shaped, namely, the variable waterseal is basin-shaped variable waterseal, comprising: a basin-shaped sewage draining passage with a axle and capable of tilt around the axle, that is supported in the supporting hole on the hoop supporter fastened with bolt on the outside of the upper chamber outlet, and the upper chamber outlet extends into the lower end of the basin-shaped sewage draining passage, and the basin-shaped sewage draining passage inclines right upwards and extends to the horizontal tilting outlet, and there exists reset counterweight on the left outside of the basin-shaped sewage draining passage; the horizontal plate on the top of the supporter is the limit plate, a bending bump is the limit bump; the bottom of the supporter is fastened by screws.  
   
   
       4 . The variable water sealed toilet bowl according to  claim 1 , wherein the described tiltable sewage draining passage is U-pipe sewage draining passage or ┐ pipe sewage draining passage.  
   
   
       5 . The variable water sealed toilet bowl according to  claim 1 , wherein a supporting axle or supporting hole is mounted on the outside of the upper chamber outlet or the lower chamber outlet in the lower chamber.  
   
   
       6 . The variable water sealed toilet bowl according to  claim 1 , wherein the reset device is selected from the counterweight reset device, the compression spring reset device or the tension spring reset device or the combined reset device of compression spring and tension spring.  
   
   
       7 . A basin-shaped variable water sealed toilet bowl according to  claim 4 , wherein the reset device is selected from the counterweight reset device, the compression spring reset device or the tension spring reset device or the combined reset device of compression spring and tension spring.  
   
   
       8 . The variable water sealed toilet bowl according to  claim 5 , wherein the reset device is selected from the counterweight reset device, the compression spring reset device or the tension spring reset device or the combined reset device of compression spring and tension spring.  
   
   
       9 . The variable water sealed toilet bowl according to  claim 2 , wherein the described tiltable sewage draining passage is U-pipe sewage draining passage or ┐ pipe sewage draining passage.  
   
   
       10 . The variable water sealed toilet bowl according to  claim 2 , wherein a supporting axle or supporting hole is mounted on the outside of the upper chamber outlet or the lower chamber outlet in the lower chamber.
