Description

Technical Field

[0001] The utility model relates to the field of black water tanks, in particular to an open black water tank for a mobile toilet. Background Art

[0002] The black water tank generally refers to a water tank for storing sewage and dirt. For example, the sewage outlet of the toilet in a recreational vehicle is connected to the black water tank to receive the sewage and dirt discharged from the toilet.

[0003] In the prior art, especially the black water tanks in recreational vehicles are generally of an integrally sealed structure. There are various inconveniences in the use of this type of black water tank. One is the inconvenience of cleaning, which is also the most serious problem, that is, the inside of the black water tank cannot be thoroughly cleaned at all. The interface is relatively small, and there are dead corners that cannot be cleaned during the process of dumping dirt and cleaning. It is also very difficult to dump it cleanly and even more difficult to rinse. After long-term use, dirt accumulates inside, and the generated odor directly returns to the toilet, seriously affecting the use experience. Second, when the black water tank is used in a sealed state for a long time, the contents can ferment to produce combustible gases, causing a fire hazard. Third, currently, degradants and biological fermentation technologies are widely used to remove odors. Although it can solve certain problems, due to the trouble in use and the occupation of the internal volume of the black water tank, and more importantly, the relatively high use cost, it is used less. To solve the problem of toilet odor, quite a number of toilets can only be left unused and regarded as decorations, while users have to go to other places for toilet convenience. This is the very embarrassing and helpless current situation in the recreational vehicle industry.

[0004] Research and design an economical and practical new solution to completely bid farewell to the embarrassment during use, completely bid farewell to the trouble of rinsing the black water tank, completely bid farewell to the helplessness of using degradants, and completely bid farewell to the reality of stinking. Making convenience an easy and happy thing is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an open split structure, and a replaceable black water bag is arranged inside, which is easy to take out and dump dirt and is also convenient to replace, and a mobile toilet open black water tank that is convenient to move itself. The device includes a box body, a box cover and a replaceable black water bag;

[0006] The top surface of the box body is in the form of an open box, and a movable box cover A and box cover B are arranged on the box body. The box cover A and box cover B are respectively arranged on both sides of the upper surface of the box body;

[0007] A replaceable black water bag is arranged inside the box body and the box cover. The black water bag is a plastic film bag. The upper end of the plastic film bag is provided with an opening, and a socket part is integrally extended upward from the opening position and fixed on a boss sealing ring. The replaceable black water bag is in a hollow shape to receive and store the sewage and dirt discharged from the toilet;

[0008] On the cover B at the upper part of the box body, there is a docking notch; on the inner side of the docking notch, there is a protruding boss sealing ring. The protruding boss sealing ring docks and elastically seals the open black water tank with the sewage outlet at the bottom of the toilet. The dirt discharged from the sewage outlet directly falls into the black water bag for storage. When the storage reaches a certain amount, the black water tank is pulled out to pour, clean, and replace the black water bag.

[0009] On the cover A at the upper part of the box body and the box body, there are respectively provided a locking notch and a locking convex structure. The effect achieved thereby is that the cover A is connected through the locking notch and the locking convex structure, ensuring the connection and fixation between the cover A and the box body.

[0010] The effect achieved thereby is that after the box body is pulled out and the cover is opened, the black water bag can be directly taken out for cleaning and replacement. Under the action of the newly replaced black water bag, the remaining feces and urine are prevented from remaining and contaminating the box body, achieving the effect of keeping the box body clean and free of odor returning to the bathroom.

[0011] The beneficial effects of the present utility model are as follows: The present utility model solves the problems in the prior art that the black water tank is inconvenient to clean, and the fermented gas and odor return to the bathroom, resulting in a stinky bathroom. It fills a gap in the market with a simple structure. Through the movably arranged box body cover and the replaceable black water bag, the fecal fermentation is completely eliminated, and the feces contaminate the black water tank. The replaceable black water bag is used as a fecal storage container, achieving the effects of convenient cleaning and replacement and no odor returning to the bathroom. Description of the Drawings
