Description

A non-water flushing toilet with urine and feces separation and a working method thereof TECHNICAL FIELD

[0001] The present application relates to a non-water flushing toilet and public health treatment technology, in particular to a non-water flushing toilet system, and more particularly to a non-water flushing toilet with urine and feces separation and a working method thereof. BACKGROUND

[0002] With the continuous development of social economy and civilization, clean and sanitary water flushing toilets provide people with a good toilet environment. At the same time, water flushing toilets cause waste of water resources. In arid and water-scarce areas and places without sewers, the construction of water flushing toilets also faces great difficulties. In the environment and scenic area with water as the theme, and in the environment and scenic area with desert and mountain as the theme, it is not convenient to build sewage pipes and sewage pipes. The large amount of sewage discharge of water flushing toilets puts great pressure on the end sewage treatment, and frequent cleaning increases the use cost.

[0003] A large number of market research shows that the toilet available for use in areas where water is not convenient is mostly packaged toilet, microbial toilet and dry toilet. The plastic bag in the waste of packaged toilet is difficult to handle in the later stage, causing secondary pollution to the environment. The small toilet of microbial toilet technology needs to be handled separately, and the harmless treatment technology of feces by microorganisms is not good, the power consumption is large, and the use effect is not good. The common problems also include that the toilet cannot be flushed due to the separation from water source.

[0004] Several toilet technologies that can achieve flushing without water have been disclosed in the prior art, and the technical features of all of them are to collect urine and process it into flushing liquid to flush feces. For example:

[0005] The technical solutions disclosed in patent application number CN01109097.9, patent application number CN201911272844.0 and patent application number CN201720406455.2 also involve non-water flushing technology, but they all have problems such as complex structure, high manufacturing cost, high failure rate or lack of technical feasibility, which cannot be effectively applied in practice. Among them, the patent technology of patent application number CN01109097.9 has a complex structure and high manufacturing cost; the patent technologies of patent application number CN201911272844.0 and patent application number CN201720406455.2 lack technical feasibility. Specifically:

[0006] (1) The urine purification device of the technical solution of patent application number CN201720406455.2 is a reclaimed water treatment device, which is used for filtering, sterilizing, anaerobic reaction and aerobic reaction treatment of collected urine. The use of such a treatment process has high equipment cost and operation cost, and the operation of the equipment requires high management personnel. Such a reclaimed water treatment device is even difficult to achieve harmless treatment of urine, so the use of treated urine to flush the toilet cannot play a role in cleaning the toilet.

[0007] (2) The technical solution of patent application number CN201720406455.2 is provided with a foam generating device, which also greatly increases the system equipment cost. In addition, the foaming agent of the foam generating device needs a diluent to reduce the concentration of the foaming agent for use. If the treated urine is used as the diluent, the foaming effect is not good. If water is used as the diluent, the water consumption per person is more than 50ml, so this technical solution is not a truly water-free toilet product.

[0008] (3) In the technical solution of patent application number 201911272844.0, the flushing pipe is arranged around the upper edge of the feces collection area and the urine collection area. The flushing pipe is provided with a plurality of flushing nozzles. One end of the flushing pipe is installed in the area of the feces collection area and the urine collection area, and the other end is in communication with the flushing pump. One end of the urine suction pipe is in communication with the flushing pump, and the other end is in communication with the urine collection tank. In this way, the feces collection area and the urine collection area are flushed after each toilet use, and the feces collection area and the urine collection area cannot be flushed separately. The consequence is that the amount of collected urine is not enough, and water-free flushing cannot be achieved. This patent has a congenital defect in functional design.

[0009] Therefore, there is a technical need to design a new structure of water-free flushing toilet that can achieve feces and urine separation.

The above various deodorants or deodorization schemes are known in the art and are not described in detail in the present application.

[0052] Unlike the concept or impression of most people, fresh urine not only has no odor, but also has no bacteria. Urea in fresh urine does not produce odor, and after being discharged from the body, urea is decomposed by microorganisms into ammonia water, which produces a strong irritating odor. Fresh urine treated by a deodorant can be used as a flushing liquid based on the above reasons.

[0053] As a preferred embodiment, the urine collecting sub-system has a liquid volume testing device for controlling the amount of water added to the urine collecting sub-system before the first use of the feces and urine separating waterless flush toilet under the cooperation of the water full alarm prompt unit of the control device.

When the water reaches the set volume, the control device 5 is provided with a full water alarm prompt. Before the first use of the excrement and urine separation waterless flushable toilet, since no water is added in the excrement collection tank 4 (here, the mark 4 represents the combination of all excrement collection tanks), when the excrement collection tank needs to be flushed, the control device 5 will suspend the operation of the excrement collection tank coarse flushing pump 42 and prolong the operation time of the excrement collection tank flushing pump 33, so as to ensure the clean flushing of the excrement collection tank 1 and provide urine for flushing the excrement collection tank 1. When the liquid level of the excrement collection tank 4N reaches the pre-set volume, the excrement collection tank liquid level sensor 43 transmits a signal to the control device 5, and the control device 5 restores the normal working procedure.

[0055] In this embodiment, the excrement and urine separation waterless flushable toilet in use, since the number of people using the toilet for urination and defecation is different in different places, the urine volume collected by the urine collection tank 3 and the excrement collection tank 4 will be different. Especially when the number of people using the toilet for defecation is relatively large and concentrated, the urine in the excrement collection tank 4N will be reduced to a state of lack of urine. The excrement collection tank liquid level sensor 43 transmits a signal to the control device 5. At this time, when the defecation flushing process is performed, the control device 5 will suspend the operation of the excrement collection tank coarse flushing pump 42 and prolong the operation time of the excrement collection tank flushing pump 33, so as to ensure the clean flushing of the excrement collection tank 1 and provide more urine for flushing the excrement collection tank 1. When the liquid level of the excrement collection tank 4N reaches the pre-set volume, the excrement collection tank liquid level sensor 43 transmits a signal to the control device 5, and the control device 5 restores the normal working procedure.

[0056] As a preferred embodiment, the first self-discharge subsystem and the second self-discharge upper part are provided with a filtering component.

[0057] In this embodiment, the excrement and urine separation waterless flushable toilet in use, since the number of people using the toilet for urination and defecation is different in different places, the urine volume collected by the urine collection tank 3 and the excrement collection tank 4 will be different. Especially when the number of people using the toilet for defecation is relatively large and concentrated, the urine in the excrement collection tank 4N will be reduced to a state of lack of urine. The excrement collection tank liquid level sensor 43 transmits a signal to the control device 5. At this time, when the defecation flushing process is performed, the control device 5 will suspend the operation of the excrement collection tank coarse flushing pump 42 and prolong the operation time of the excrement collection tank flushing pump 33, so as to ensure the clean flushing of the excrement collection tank 1 and provide more urine for flushing the excrement collection tank 1. When the liquid level of the excrement collection tank 4N reaches the pre-set volume, the excrement collection tank liquid level sensor 43 transmits a signal to the control device 5, and the control device 5 restores the normal working procedure.
