A caravan and its feces collection system

Abstract

The invention discloses a motor home and a defection collection system thereof. The system comprises a collection cabin, a closestool which is embedded in the collection cabin in a turndown manner and a sewage collection device communicated with the sewage outlet of theclosestool, wherein a folding device is arranged between the closestool and the collection cabin, and the closestool is turned in or out relative to the collection cabin by virtue of the folding device; the sewage collection device comprises a sewage tank; a sewage inlet, a fan extraction opening and a drain outlet are formed in the sewage tank; the sewage inlet is communicated with the sewage outlet of the closestool through a sewage pipeline; the fan extraction opening is communicated with a fan; and the drain outlet is communicated with the space outside the vehicle through a draining valve. According to the defection collection system, theclosestoolcan be folded for storage, so that space interference between theclosestooland shower can be avoided, the space utilization is improved, and user experience is improved; furthermore, the draining efficiency and draining capacity are improved by adopting an extraction draining mode.

Description

technical field [0001] The invention relates to the technical field of caravan auxiliary facilities, in particular to a feces collection system for a caravan. The present invention also provides a caravan comprising a feces collection system. Background technique [0002] A caravan is a mobile car with the basic facilities necessary for home. It has a driving area, a living area, a bedroom area, a sanitary area, a kitchen area, etc. The caravan is a collection of "clothing, food, housing, and transportation". All in one, realize the fashion product of "travel in life, life in travel". The feces collection system is used to collect and temporarily store the excrement of passengers, so that it can be discharged into the municipal sewer pipeline in the campsite. It includes toilets, dirt tanks, flushing equipment, etc., and is an essential sanitary equipment for RVs. [0003] The existing feces collection system mainly has two structural forms according to the working princip...

AI Technical Summary

Problems solved by technology

In addition, the outer diameter of the bedpan in the feces collection system is usually smaller than that of the domestic toilet, the seat is positioned high and the contact area with the buttocks is small, and the comfort is poor

[0005] In addition, in the feces collection system that uses gravity to collect, the user needs to manually open the drain valve when emptying the bedpan. Since the dirt tank is closed, the air inside must overflow from the open drain valve when the dirt falls into the dirt tank. Pollution, on the one hand odor pollution and on the other hand bacteria-laden droplets that can contaminate nearby surfaces, posing a health risk if someone later touches these surfaces

Therefore, such products usually need to use special chemicals and put them into the dirt tank to inhibit the odor and bacterial growth, the effect is mediocre and it is an extra cost

Moreover, the dirt tank is usually detachable and movable. The user needs to dismantle the dirt tank and carry it to the sewage discharge point of the camp, and dump the dirt into the sewer. This operation requires manpower, and the operator will see the dirt flow out. Unhygienic and very uncomfortable experience

To sum up, there are many manual operations, pollution is inevitable, and the experience is not good

[0006] The problem with the electric sewage pump system is that each flush requires 1.5 to 2 liters of water to be discharged along with the excrement, resulting in a large amount of water consumption and high water content in the sewage. The same number of times the toilet is used requires a larger clean water tank and sewage on the vehicle. The volume of the box, taking up space and adding unnecessary weight
