BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flushing system, and more particularly to a system for storing and utilizing water that can be directly reused in domestic sewage for flushing. BACKGROUND OF THE INVENTION At present, water resources are one of human precious natural resources. Many countries in the world are facing the problem of lack of fresh water resources. For this reason, the United Nations has designated March 22 every year as "World Water Day" to vigorously advocate Protect water resources, save water and change water use. In daily life, people need to wash their face, wash laundry, wash vegetables and wash, etc., and consume a lot of tap water, especially the most water-consuming. Therefore, the Ministry of Construction issues mandatory provisions: Washing water for each flush cycle of the product The amount is not more than 6 liters. When the water pressure is 0.3Mpa, the product for stool flushing has a flushing capacity of 6-8 liters, and the flushing product has a flushing volume of 2 to 4 liters. In fact, flushing water does not require high water quality. It can be done by using existing wastewater, such as washing, washing vegetables and washing water. Since it does not contain oil impurities, it can be used directly without chemical or physical treatment. Rush. Existing systems or devices that collect domestic sewage for flushing usually collect all domestic sewage such as face washing, dish washing, and laundry, and then use physical and chemical treatment methods for treatment. This often requires the addition of power equipment, or the construction of the device to occupy a limited living space, complex structure, inconvenient to use, is not conducive to promotion in general households, hotels and public toilets. SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a water-saving flushing system that is simple in structure, low in cost, and easy to implement in general households, households, and public toilets. To this end, the water-saving flushing system provided by the utility model comprises a domestic water tank and a flushing water tank, and a domestic sewage water tank is arranged below the living water tank, and the living water tank has two water holes, one of which passes through the water hole The pipeline is connected to the sewer port, and the pipeline is arranged in a groove on the outer side wall of the domestic sewage treatment tank, and the sewage outlet at the lower end of the domestic sewage treatment tank passes through the conveying pipe and the flushing water. The sewage inlet at the lower end of the tank is connected, and a water level control device is arranged above the inner end of the sewage inlet, and a check valve is arranged in series on the conveying water pipe near the flushing water tank, and the groove wall of the domestic sewage treatment water tank is provided with an overflow near the upper end The flow port, the outer end of the overflow port is connected to the sewer port through a pipe. ■ 'The utility model utilizes domestic sewage which can be directly used twice in the daily life as one of the water sources of the flushing water tank. When the domestic sewage generated in the domestic water tank contains oil or other impurities that are difficult to clean, one of the drains is directly discharged into the sewer through the pipeline; if the domestic sewage generated after washing the face, washing hands or washing vegetables in the domestic sink is more When cleaning, it is temporarily stored in the domestic sewage treatment tank below the other water outlet. When the water level in the flushing tank drops and the water level of the domestic sewage in the domestic sewage treatment tank is sufficient, the domestic sewage enters the flushing water tank from the domestic sewage treatment tank through the conveying water pipe, and is used as a common water source for flushing with the tap water. Under normal circumstances, the tap water connected to the flushing water tank is normally closed. Try to use the water sent from the domestic sewage treatment tank to flush the toilet or the toilet. When the water in the domestic sewage treatment tank is not enough, the tap water switch is turned on, and the tap water is used. Rush. When space permits, a dedicated water storage tank can be added between the domestic sewage treatment tank and the flushing water tank to store and utilize domestic sewage more. Compared with the conventional flushing water tank which only uses tap water as the water source, the consumption of tap water is greatly saved, thereby achieving the purpose of saving water. The utility model has the beneficial effects that the clean domestic sewage generated by people's daily life can be stored and used as a common water source for the flushing with the tap water, and the whole system has a simple structure, and the existing living water tank and the flushing water tank are provided. The structure is not changed greatly, nor is it added to other power equipment or complex physical and chemical treatment equipment, and the cost is low, and it is easy to promote and apply in general households, hotels and public toilets. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing the overall configuration of an embodiment of the present invention. 2 is a schematic view showing the structure of the domestic water tank 1 and the domestic sewage treatment water tank 3 below the embodiment of the present invention. Figure 3 is a rear elevational view of Figure 2. 4 is a schematic view showing the structure of the flush water tank 2 in the embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. As shown in Fig. 1, the water-saving flushing system provided by the utility model has a domestic water tank 1 and a flush water tank 2, and a domestic sewage water tank 3, a domestic water tank 1 and a flush water tank are arranged below the domestic water tank 1. A special water storage tank 12 is installed on the water supply pipe 4 between the two, and the special water storage tank 12 is also connected to the drain pipe of the washing machine 13 through the water supply pipe 4. There are two flushing water tanks 2, one is a water tank matched with the toilet, and the other is a water tank matched with the squat toilet. The two flushing water tanks have the same structure. A check valve 9 is connected in series to the transfer water pipe 4 between the dedicated water storage tank 12 and the two flush water tanks 2 to prevent backflow of water. When the components of the system are arranged in different rooms of the same floor building, the washing machine 13 should adopt an upper drainage structure as shown in FIG. As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the domestic water tank 1 has two drain holes la and lb, one of which is connected to the sewer port 17 through a duct 5, which is arranged in domestic sewage. The inside of the groove 3c of the outer side wall of the water tank 3 is treated, so that the pipe 5 does not occupy other space, and the installation and arrangement of the domestic sewage treatment water tank 3 in the room are facilitated. The wall of the recess 3c of the domestic sewage treatment tank 3 is provided with an overflow port 3b near the upper end, and the outer end of the overflow port 3b communicates with the sewer port 17 through the duct 5, when the water level of the domestic sewage treatment tank 3 reaches the overflow port 3b At the time, the sewage is discharged through the pipe 5 to the sewer. The sewage outlet 3a at the lower end of the domestic sewage treatment tank 3 is connected to the sewage inlet 2a at the lower end of the flushing water tank 2 through a water delivery pipe 4, and a water level control device 11 is provided above the inner end of the sewage inlet 2a, when the water level in the flushing water tank 2 reaches the allowable level At the highest 7 digits, the 7j position control device 11 closes the sewage inlet 2a; when the water level in the flush tank 2 reaches the lower limit, the 7j position control device 11 opens the sewage inlet 2a. The water level control device 15 connected to the water pipe in the flush water tank 2 is an upper water inlet structure, and the water outlet control device 15 has a drain port 15c at the drain key 15b higher than the highest water level of the water tank, and the wall of the float pipe 15d at the water level control device 15 The upper opening has a vent hole 15a, the vent hole 15a is positioned higher than the highest water level of the water tank, and the drain port 15c communicates with the vent hole 15a, so that when the water pipe 14 connected to the water level control device 15 is in an open state and suddenly stops water, the tap water A negative pressure is generated in the tube 14, and the vent hole 15a prevents the dirt at the bottom of the flush tank 2 from being sucked into the water pipe 14 under a negative pressure. The water level control device 15, the water button flushing valve 16 for controlling the flushing amount, and the water level controlling device 11 for controlling the opening and closing of the sewage inlet 2a are both conventional structures. The height of the overflow port 3b of the domestic sewage treatment tank 3 preferably coincides with the highest water level of the dedicated water storage tank 12 and the flush water tank 2. Reference numeral 2b in Fig. 4 is a flushing port connected to the bowl. 2 and 3 show that the inner bottom of the domestic sewage treatment tank 3 is provided with a sewage pipe ditch 6, and the sewage pipe ditch 6 can be convexly or concavely disposed at the bottom of the domestic sewage treatment tank 3 and made into a domestic sewage treatment tank 30. One. One end of the sewage pipe ditch 6 is provided with a sewage inlet 6a, and the other end of the sewage outlet 6b is connected to the sewer port 17 in the outer side wall groove 3c of the domestic sewage treatment tank 3 via a pipe 5, and a sewage cover 7 is arranged above the sewage inlet 6a. The drain cover 7 is attached to the pulling rod mechanism 8. The dirt deposited on the bottom of the domestic sewage treatment tank 3 can open the sewage inlet 6a on the sewage pipe groove 6 by periodically or irregularly operating the lifting bar +f mechanism 8, thereby allowing the dirt to be discharged into the sewer. It can be seen from Fig. 2 and Fig. 3 that a spherical filter cover 10 is disposed inside the sewage outlet 3a at the lower end of the domestic sewage treatment tank 3, so that the domestic sewage entering the delivery water pipe 4 through the sewage outlet 3a is filtered, and the spherical mesh cover is filtered. It can effectively prevent dirt from accumulating on the net cover and affect its filtering function. The sewage outlet 3a is located higher than the sewage inlet 6a of the sewage pipe ditch 6. The domestic water tank 1 of the utility model can also be two independent water tanks, one water tank for generating relatively clean domestic sewage, and the other water tank for generating domestic sewage which should be directly discharged into the sewer. The domestic water tank 1 can also be any other structure, as long as the domestic sewage can be used in a differentiated manner, and the domestic sewage that can be directly used twice can be discharged into the domestic sewage treatment tank 3 below.
