Description

Bilge water resisting returns excessive water closet

Affiliated technical field

The utility model relates to a kind of sanitaryware, especially a kind ofly can return excessive water closet by bilge water resisting.

Technical background

Existing water closet comprises the base of storage tank, band urinal and sewer, this kind water closet when line clogging takes place, sewage easily along the sewer overflow to the washroom, contaminated environment, even whole room.In addition, when the water closet sewer stops up, not easy to clean mediation.

Summary of the invention

At existing problem in the above-mentioned prior art, the utility model provides a kind of bilge water resisting to return excessive water closet, also is convenient to the cleaning mediation simultaneously.

Its technical solution is that this bilge water resisting returns excessive water closet, the base that comprises storage tank, band urinal and sewer, the bottom that it is characterized in that described sewer is provided with float cabin and the earial drainage chamber that all communicates with sewer, be provided with the passage that communicates between the two, be provided with movable ball float in the described float cabin, the diameter of ball float greater than sewer with the diameter of float cabin junction and also greater than the earial drainage chamber with the diameter of sewer junction, also be greater than the channel pitch that communicates between float cabin and the earial drainage chamber simultaneously, be provided with access hole at the rear lower of base.

Its beneficial effect is that when line clogging, ball float seals sewer, prevents the sewage overflow owing to be provided with float cabin and earial drainage chamber; Because the rear lower at base is provided with access hole, can be convenient to change ball float and clear up relevant dirt.

Description of drawings

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that float cabin and earial drainage chamber concern schematic diagram among Fig. 1.

Among the figure, 1-storage tank, 2-urinal, 3-base, 4-sewer, 5-float cabin, 6-earial drainage chamber, 7-access hole, 8-ball float.

The specific embodiment

Accompanying drawing 1, shown in Figure 2, this bilge water resisting returns excessive water closet, comprises the base 3 of the storage tank 1, band urinal 2 and the sewer 4 that communicate with urinal.The bottom of described sewer 4 is provided with float cabin 5 and the earial drainage chamber 6 that all communicates with sewer, be provided with the passage that communicates between the two, from the current that sewer comes, a part is descending through earial drainage chamber 6, and another part is descending behind the passage between float cabin and float cabin and the earial drainage chamber.Be provided with movable ball float 8 in the described float cabin 5, the diameter of ball float 8 greater than sewer 4 with the diameter of float cabin 5 junctions and also greater than earial drainage chamber 6 with the diameter of sewer junction, also be greater than the channel pitch that communicates between float cabin 5 and the earial drainage chamber 6 simultaneously, thereby ball float can only move freely in float cabin.Rear lower at base 3 is provided with access hole 7, the also sealing on base by screw thread or bolton of this access hole.

Owing to be provided with float cabin and earial drainage chamber, when line clogging, ball float seals sewer, prevents the sewage overflow; Owing to the rear lower at base is provided with access hole, can be convenient to change ball float and clear up relevant dirt again.
