Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art As shown in FIGS. 3 and 4, a well-known fecal height detecting device for a feces tank provided in ships and other transportation means has one fixed seat 4 and a bottom portion of the fixed seat 4. One sensor rod 6 is provided at the center of the sensor rod 6, an elevating rod 7 is slidably fitted below the sensor rod 6, and a silicone rubber bellows tube 5 is fitted to the outside of the elevating rod 7 and the sensor rod 6, and a screw 82 The fixing seat 4 is fixed to the main body 82 of the feces tank, and the silicone rubber bellows tube 5 contracts and rises due to the elevation of the feces, or is processed, and the elevating rod 7 also rises and lowers accordingly.
It is designed to detect the height of the feces collected in the. However, in such a conventional feces advanced detection device, the feces or other waste 81 is not used when the silicone rubber bellows tube 5 is used.
The concave portion 52 on the outer periphery of the rubber was easily clogged, which sometimes prevented the silicone rubber bellows tube 5 from accurately detecting the height of feces. For this reason, a situation in which the feces overflow from the feces tank often occurs, and in order for the silicone rubber bellows tube 5 to normally expand and contract, a pore 41 is provided in the fixed seat 4 so that air communicates with the inside of the silicone rubber bellows tube 5. There is. However, when the silicone rubber bellows tube 5 used in the conventional feces advanced detection device is used for a certain period of time, the broken line portion 51 of the silicone rubber bellows tube 5 is apt to be ruptured, which causes feces and wastes. The silicone rubber bellows tube 5 may enter the silicone rubber bellows tube 5 and may not be able to normally move up and down to be unusable, and odor may be discharged from the pores 41 of the fixed seat 4 to fill the room. Has caused problems in use.
