DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stool height detecting device for a stool tank of a kind of traffic tool.

[0002]

2. Description of the Related Art As shown in FIGS. 3 and 4, a well-known stool height detecting device for a stool tank provided on a ship and other transportation means has one fixed seat 4, and a bottom portion of the fixed seat 4. A sensor rod 6 is provided at the center of the sensor rod 6, a lifting rod 7 is slidably fitted below the sensor rod 6, a silicone rubber bellows tube 5 is fitted on the outside of the lifting rod 7 and the sensor rod 6, and a screw 82 The fixing seat 4 is fixed to the stool tank main body 82, and the silicone rubber bellows tube 5 contracts or rises or is processed by raising and lowering the stool.
The height of the stool accumulated in the water is detected. However, such a conventional stool height detection apparatus is characterized in that the stool or other waste 81 is used when the silicone rubber bellows tube 5 is used.
In some cases, the concave portion 52 on the outer periphery of the stool may be easily clogged, which may make it impossible for the silicone rubber bellows tube 5 to accurately detect the stool height. For this reason, the stool often overflows from the stool tank. In addition, since the silicone rubber bellows tube 5 normally expands and contracts, the fixed seat 4 is provided with pores 41 to allow air to communicate with the inside of the silicone rubber bellows tube 5. It is. However, the silicone rubber bellows tube 5 used in the conventional stool height detection device, when used for a certain period of time, is very likely to rupture at the fold line portion 51 of the silicone rubber bellows tube 5, whereby feces and wastes are removed. When the silicone rubber bellows tube 5 enters the silicone rubber bellows tube 5, the silicone rubber bellows tube 5 cannot be moved up and down normally and becomes unusable, and the odor is released from the pores 41 of the fixed seat 4 and may fill the room. Resulted in usage problems.
