A water-saving toilet tank

technical field

The utility model relates to a water-saving sanitary ware, in particular to a water-saving toilet water tank.

Background technique

As we all know, my country is one of the countries short of water in the world, and the per capita water resources are only a quarter of the world's per capita water resources. The shortage and pollution of water resources have seriously affected my country's national economic construction and people's normal life. . At present, domestic water for toilet flushing is mainly clean tap water. For toilet flushing alone, my country consumes about 10 billion cubic meters of tap water every year, which is equivalent to the annual tap water consumption of 50 medium-sized cities. Therefore, a large amount of precious water resources in our country have only played the minimum function every year, and are wasted like this. And some developed countries have laid water recycling pipelines, and centralized treatment, used to provide residents to flush toilets.

At present, the method of flushing toilets with reclaimed water has attracted attention. The recycling of reclaimed water within the community or unit has been implemented in some areas, and after treatment, it is transported to various households or departments as water for flushing toilets. Another method is to flush the ecological toilet with circulating water. After the flushing water enters the septic tank, it is treated to become reclaimed water that can be flushed again, and the toilet is circulated for flushing. There are also people who propose laying reclaimed water recycling pipelines across the country, and after purification, enter reclaimed water tanks like supplying tap water. In the above method, the sewage needs to be treated by sedimentation, filtration, disinfection and other processes before it can be purified into clear reclaimed water. The purification measures are expensive, the procedure is complicated, and its safety needs further verification, and it may cause viruses, microorganisms, Chemical and other secondary pollution. The difficulties in laying reclaimed water pipelines are obvious, involving many aspects such as capital, manpower, environment, ecology, etc., at least currently it is not feasible.

In view of the impracticability of the above schemes, the technology for flushing toilets with reclaimed water used in households is a highlight, and related water-saving flushing technologies and products have been developed. For example, a simple toilet tank that can utilize secondary water (ZL02245769) relates to a simple and convenient toilet tank device that can be flushed with secondary water and clean water (tap water). Rod, clean water inlet valve, secondary water inlet valve, water purification section door switch, water discharge valve and corresponding pipelines. By adding a set of secondary water inlet valve device, the purpose of secondary water utilization can be achieved. It can control the use of purified water and secondary water separately, and can also use secondary water and purified water together. It can also automatically switch to a water tank using purified water when the secondary water is exhausted. And a kind of toilet water tank (ZL200620001919.3) that domestic waste water and tap water are coordinated flushing, its internal structure divides water tank into two water storage chambers of large and small by a dividing plate, and the dividing plate top is provided with a balance port, and the bottom is provided with a communication valve. Press the flushing button, and the water in the large chamber is discharged into the toilet. When it is about to be drained, the communication valve is automatically opened, and the water in the small chamber enters the large chamber and is discharged into the toilet to complete the flushing process. The above-mentioned products have the disadvantages of complex structure or the need to manually inject waste water into the water tank, which is inconvenient to use in daily life. Due to the use of a connecting valve, cost and service life are issues that have to be considered.

Compared with the above designs, in addition to saving water, another key issue of the reclaimed water reuse toilet flushing device for household use is that it is economical, practical and easy to use.

Contents of the invention

The purpose of the utility model is to provide a water-saving toilet water tank, which can overcome the shortcomings of the existing products such as complex structure design and high cost, which can not only simplify the structure of the water tank, reduce the cost of the product, but also facilitate the use of reclaimed water or The toilet is flushed with tap water, and the total water consumption is basically unchanged according to the water volume of reclaimed water, so as to save water resources as much as possible.

The technical scheme that the utility model adopts is as follows:

A water-saving toilet water tank, including a running water tank, characterized in that: the toilet water tank also includes a reclaimed water tank, the reclaimed water tank includes a water inlet, a water discharge port, a water discharge piston and a floating ball, and the water discharge port of the remedial water tank passes through the water discharge port of the tap water tank The pipeline is connected, and the opening of the water discharge piston of the middle water tank and the tap water tank is controlled by a water discharge switch; the floating ball is connected with the water discharge piston of the tap water tank by a connecting rod.

The reclaimed water enters the reclaimed water tank through the water inlet, and the floating ball in the reclaimed water tank is affected by the buoyancy, and is transmitted to the water discharge piston of the tap water tank through the connecting rod. Adjust to achieve the purpose of using reclaimed water. When the middle water tank is full of water, the floating ball is subjected to the greatest buoyancy, and the force transmitted to the water discharge piston through the connecting rod is the largest, and the water discharge piston falls quickly, and all the reclaimed water enters the toilet, and tap water hardly enters the toilet. When the water in the middle water tank is not full, the float ball is subjected to less buoyancy, and the force passed to the water discharge piston by the connecting rod is less, and the water discharge piston slowly falls, and all the middle water enters the toilet, and the tap water partly enters the toilet. When there is almost no water in the middle water tank, the float ball is hardly affected by buoyancy, and the force transmitted to the water discharge piston by the connecting rod is almost zero, and the water discharge piston remains suspended, and almost all the tap water enters the toilet.

Described connecting rod is made up of connecting rod one and connecting rod two, and connecting rod one and connecting rod two are rotationally connected, and connecting rod one is fixedly connected with floating ball, and connecting rod two is fixedly or rotationally connected with tap water tank discharge piston; Rotate around a fixed fulcrum on the water tank. Fixed fulcrum can be arranged on the casing of tap water tank or intermediate water tank, or be arranged on the dividing plate of tap water tank and intermediate water tank.

The toilet water tank is under the condition that the middle water tank is full of water (suffering buoyancy is maximum), and the tap water tank discharges no more than 1L. Determine the shape of the floating ball accordingly, and when the water surface of the middle water tank is at any height, the total water discharge of the two water tanks can be basically unchanged (within 6-10L). Preferably, the floating ball is a cuboid.

When there is no water in the middle water tank, the floating ball has no buoyancy. For the convenience of use, the tap water tank discharge piston is the same as the piston in the traditional water tank, and is not affected by the connecting rod and the floating ball. A counterweight can be added to it. And the weight of the water discharge piston and the force balance that the connecting rod and the floating ball exert on the piston.

The structure of above-mentioned running water tank is identical with traditional toilet water tank structure, can adopt existing water tank structural form and size, and its structure usually comprises water discharge port, water discharge piston and water discharge switch except water inlet and control part. The utility model can improve the traditional water tank without changing the design of the tap water tank.

The water-saving toilet water tank described in the utility model can effectively recycle and utilize reclaimed water resources, and save water resources as much as possible. The traditional water tank can be improved without changing the design of the tap water tank, the total water consumption is basically unchanged, the structure is simple, and no additional maintenance costs are required. The cost of producing the water tank is almost the same as that of the traditional water tank, and the cost is lower. More importantly, it saves non-renewable water resources and alleviates the current shortage of water resources. If the utility model is accepted and popularized by ordinary residents and relevant government agencies and units, with the calculation of 2.5 yuan per ton of tap water and 60% reclaimed water reuse rate, and reclaimed water accounts for 30% of the toilet flushing water, the tap water fee saved every year is 100 * 2.5 * 60% * 30% = 4.5 billion yuan, so there are about 4.5 billion yuan of water-saving benefits every year, reducing household water expenses and saving social resources.

The utility model will be described in detail through specific embodiments below in conjunction with the accompanying drawings. The protection scope of the utility model is not limited by the specific implementation, but by the scope of the claims.

Detailed ways

A water-saving toilet water tank, as shown in Figure 1, the water tank is divided into two parts, the middle water tank (i.e. the water tank for storing domestic water) and the tap water tank, the left side is the middle water tank 1, the right side is the tap water tank 2, and the middle is separated by a partition 13 open. Tap water tank 2 is cuboid, and size is 20 * 20 * 30cm (the same as traditional toilet water tank). Middle water tank 1 shell size is except that width is 30cm, and all the other are the same with tap water tank 2, and middle water tank size is 20X30X30cm, and increasing middle water tank width is in order to increase the capacity of middle water storage.

The structure of tap water tank 2 is identical with traditional toilet water tank structure, except water inlet and control part (not shown in the figure), comprises water discharge port 7, water discharge piston 8 and water discharge switch 9. The middle water tank comprises a water inlet 3, a water discharge port 4, a water discharge piston 5 and a float 6.

The reclaimed water is received in the reclaimed water tank 1 of the toilet for storage, and a grid is used in the middle to prevent solid debris from entering the reclaimed water tank 1 and blocking the pipeline. Reclaimed water comes from water facilities such as pools, which can be divided into two types: heavily polluted domestic water pools and lightly polluted domestic water pools, namely reclaimed water pools (some water with visual and olfactory pollution is not suitable for flushing toilets). The former is directly connected to the sewer, and the latter is used to flush the toilet.

The middle water tank water outlet 4 is communicated with the tap water tank water outlet 7 by the pipeline 12, and the opening of the middle water tank water discharge piston 5 and the tap water tank water discharge piston 8 is controlled by the water discharge switch 9; the float ball 6 is connected with the water discharge piston 8 of the tap water tank by a connecting rod. There is a metal counterweight 16 on the water discharge piston 8 of the tap water tank, and the weight of the counterweight 16 and the water discharge piston 8 is balanced with the force of the connecting rod and the floating ball 7 to the piston 8.

The connecting rod is composed of two parts, including connecting rod one 10 and connecting rod two 11. Connecting rod one 10 is the hard rod of a bend, can rotate in a plane around the fulcrum 14 on the dividing plate without friction, and fulcrum 14 is positioned at the water surface top of middle water tank 1 and tap water tank 2. One end of connecting rod one 10 is fixed on the floating ball 6, and the other end is rotationally connected with connecting rod two 11. One end of connecting rod two 11 is rotatably connected with connecting rod one 10, and the other end is rotatably connected on the water discharge piston 8 of the tap water tank.

The floating ball 6 in the middle water tank 1 is subjected to the buoyancy effect, and can be delivered to the tap water tank water discharge piston 8 by the connecting rod, thereby the water discharge is controlled and regulated. When there was water in the middle tank 1, the buoyancy of the ball float 6 made connecting rod one 10 upwards to be carried, and connecting rod two 11 was pushed down to withstand the tap water tank draining piston 8, and the tap water tank draining piston 8 was closed. When middle water tank 1 did not have water, ball float 6 did not have buoyancy, and because the effect of counterweight metal block 16, the water-discharging piston 8 in the tap water tank was not affected by connecting rod and ball float 6.

Open the water discharge switch 9, the middle water tank discharge piston 5 and the tap water tank discharge piston 8 are opened simultaneously, and tap water and reclaimed water are released simultaneously, but because the connecting rod can press down the discharge piston 8 of the tap water tank, it is quickened to close, so that the outlet of the tap water tank 2 The amount of water will be adjusted according to the different water volumes of the reclaimed water tank 1 (the buoyancy of the floating ball 6 is different), so that when the reclaimed water in the reclaimed water tank 1 is at different water levels, the total water discharge of the two water tanks is basically between 6 and 10L, achieving good toilet flushing Effect.

Float 6 is a cuboid that is 5 cm wide, 3 cm long, and 20 cm high. Under the condition that the middle water tank 1 is full of water and the buoyancy is the largest, the tap water tank 2 discharges no more than 1 L, which can just make the buoyancy of the float 6 larger than 1 L. Control the water discharge piston 8 of the tap water tank, that is: when the middle water tank 1 is full of water, the floating ball 6 is subjected to the maximum buoyancy, and the force passed to the water discharge piston 8 by the connecting rod is the largest, and the water discharge piston 8 falls quickly, and all the middle water enters the toilet. The tap water barely goes into the toilet. When the middle water tank 1 was not full of water, the float 6 was subjected to less buoyancy, and the power passed to the water discharge piston 8 by the connecting rod was less, and the water discharge piston 8 slowly fell, and the middle water all entered the toilet, and the tap water part entered the toilet. When water tank 1 was almost without water in the middle, ball float 6 was hardly subject to buoyancy, and the power passed to water-discharging piston 8 by connecting rod was almost zero, and water-discharging piston 8 remained suspended, and tap water almost all entered the toilet.

An overflow port 15 can be established on the top of the reclaimed water tank 1 (under the condition of reclaimed water pipeline, the reclaimed water tank can be filled with water control parts), to control the reclaimed water tank 1 water level.

The total water discharge of the water-saving toilet tank in this example under different reclaimed water volumes is shown in Table 1:
