Description

Technical Field

[0001] This invention relates to the field of flushing equipment technology, and in particular to an ultra-efficient, water-saving high-pressure flushing device for toilets that mixes air and water. Background Technology

[0002] Currently, the water-flushing toilets commonly used in rural areas employ a method of directly connecting the water pipe to the toilet tank or water inlet. When flushing is needed, the water valve is opened for a direct flow of water, and the valve is closed after flushing. According to research, this type of toilet uses 4-6L to 6-10L of water per flush, which not only consumes a large amount of clean water but also increases the cost of collecting and treating rural domestic sewage.

[0003] Ultra-efficient water-saving sanitary ware is a crucial black water collection unit in rural domestic sewage gray-black separation treatment models. Unlike urban sanitary ware (such as flush toilets), rural sanitary ware connects directly to septic tanks via inclined pipes, and the internal structure lacks long horizontal pipes. Therefore, the design of the sanitary ware does not require a large flush volume to avoid clogging. Consequently, rural water-saving sanitary ware should be more water-efficient than urban sanitary ware. The smaller flush volume significantly reduces the amount of black water and increases its concentration, effectively improving the efficiency of black water resource utilization. The ultra-low flush volume results in longer septic tank cleaning cycles, significantly improved harmlessness, smaller biogas slurry volume, and higher nutrient concentration, reducing labor intensity. For applications requiring composting (such as in-situ fermentation bed composting), it can also meet the concentration requirements for composted manure.

[0004] Greywater / blackwater separation is a wastewater collection model that separates and treats wastewater at its source at the household level, and is an important prerequisite for rural wastewater treatment and resource utilization in my country. Blackwater refers to flushing water from toilets, containing a mixture of diluted urine, feces, and other pollutants, as well as high-concentration wastewater, characterized by small volume and high pollutant concentration. Greywater refers to other domestic wastewater from sources other than toilets, including wastewater from kitchens, laundry, showers, handwashing, and washing fruits and vegetables, characterized by larger volume and lower concentration. Under this model, wastewater treatment facilities only treat greywater with a lower pollution load, significantly simplifying the wastewater treatment process and reducing construction and operating costs. Blackwater is collected and treated separately, using different treatment methods tailored to local conditions (such as straw-based in-situ fermentation beds, anaerobic fermentation for harmless treatment, etc.).

[0005] In the process of rural household toilet renovation, the design and selection of water-saving sanitary ware should fully recognize the above-mentioned background conditions, and take "low water consumption, strong cleaning power, simple structure, convenient installation and flexible layout" as the principle, combine with the local rural domestic sewage treatment system, and actively meet the needs of users. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an ultra-efficient, water-saving high-pressure flushing device for toilets that combines air and water. This device offers a solution for the treatment of rural domestic sewage by separating black and white pollutants, with minimal flushing volume, strong cleaning power, simple design, and flexible installation. It aims to resolve the adverse effects of excessively low concentrations of black pollutants in rural domestic sewage caused by the large flushing volume of conventional sanitary ware on sewage treatment and resource utilization.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A high-efficiency, water-saving, high-pressure flushing device for toilets that uses air-water mixing is characterized by comprising a water storage tank, an air-water mixing pump, and a conduit. The water storage tank includes a tank body and a lid, with the lid positioned at an opening on the top of the tank body and having a water inlet. The air-water mixing pump includes a pump body, a pressure rod, a piston, a water intake pipe, and an air-water mixing pipe. The pump body is mounted on the lid, and its upper and lower ends are interconnected air chambers and adsorption chambers. The adsorption chambers are venturi-shaped. The pressure rod is movably connected to the pump body, with its lower end connected to the piston located within the air chamber and its upper end connected to a hand-operated device. One end of the water intake pipe is connected to the adsorption chamber, and the other end is located within the tank body. One end of the air-water mixing pipe is connected to the bottom outlet of the adsorption chamber, and the other end is connected to the inlet end of the conduit. The outlet end of the conduit is connected to the toilet bowl via a nozzle.

[0009] Furthermore, the gas-water mixing pump also includes a return spring, one end of which is connected to the pressure rod and the other end is connected to the pump body, for resetting the pressure rod.

[0010] Furthermore, the bucket lid is provided with a cross beam, the water inlet is located in the gap of the cross beam, the cross beam is provided with a first opening and a second opening, the pump body is fixedly connected to the first opening, and the water pipe passes through the second opening.

[0011] Furthermore, a fixing seat is provided on the cross beam, and a fixing component is provided on the outer wall of the pump body. The fixing seat and the fixing component are connected to each other by a bracket.

[0012] Furthermore, the nozzle head has an arc-shaped structure, and a rectangular water outlet is provided on the side of the nozzle head. A nozzle sealing ring is provided at the upper end of the rectangular water outlet. A reinforcing rib is provided on the side wall of the connection area between the nozzle and the guide tube. The nozzle is connected to the toilet through the nozzle sealing ring.

[0013] Furthermore, the cross-sectional area of ​​the lower end of the air chamber gradually decreases from top to bottom, forming a funnel shape.

[0014] Furthermore, the lower end of the adsorption chamber is connected to the gas-water mixing pipe via a sealing bolt.

[0015] Furthermore, the gas-water mixing pipe and the conduit are connected by a conduit sealing ring, which is installed on the barrel body.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention utilizes the Venturi effect. By manipulating a pressure rod and piston, air in the air chamber is compressed and drawn into the adsorption chamber. As the cross-section of the air gradually decreases, the pressure of the compressed air drops sharply, while the flow rate increases. At this point, a vacuum is generated at the connection point of the water intake pipe in the adsorption chamber, causing liquid in the storage tank to be drawn into the adsorption chamber and mixed with the compressed air, flowing into the air-water mixing pipe to form a high-pressure air-water mixture that is then sprayed into the toilet bowl. Due to the intervention of high-pressure air, compared to traditional water-saving high-pressure flushers, this invention not only uses far less water (0.2-0.3 liters / flush) but also improves cleaning efficiency.

[0018] 2. When renovating or building new toilets in rural areas, this device does not need to be buried underground and can be placed around the toilet. The equipped pipes and nozzles can be used with conventional toilets, which greatly reduces the construction, installation or renovation costs.

[0019] 3. The water source used in this invention can be in various forms. The water inlet of the bucket lid can be connected to the drain pipe of the washbasin, or grey water generated from bathing, washing, etc. can be manually added, thus saving water resources.

[0020] 4. The pump body has only one air chamber instead of a separate water chamber, which reduces the pump's size, saves space, and makes the whole device more compact and flexible to install. Attached Figure Description

[0026] To enhance understanding of the present invention, we will now describe it in further detail with reference to the accompanying drawings. These embodiments are for illustrative purposes only and do not constitute a limitation on the scope of protection of the present invention.

[0027] Figure 1-4 A specific embodiment of an ultra-efficient water-saving high-pressure flushing device for a toilet with air-water mixing is shown, including a water storage tank, an air-water mixing pump, and a conduit 4; the water storage tank includes a tank body 1 and a tank cover 2, with the tank cover 2 located at the opening above the tank body 1; the air-water mixing pump includes a pump body 19, a pressure rod 16, a piston 22, a water intake pipe 20, an air-water mixing pipe 25, a return spring 21, and other structures.

[0028] Among them, such as Figure 2 As shown, the bucket lid 2 is reinforced with a cross beam 11, which can be made of channel steel or stainless steel plate. The water inlet 10 is located at the four gaps of the cross beam 11. The cross beam 11 is provided with a first opening 13 and a second opening 14. The pump body 19 is fixedly connected to the first opening 13, and the water suction pipe 20 passes through the second opening 14. Four fixing seats 12 are provided on the cross beam 11, and four fixing parts 18 are provided at corresponding positions on the outer wall of the pump body 19. The fixing seats 12 and fixing parts 18 are connected to each other one by one through the bracket 17.

[0029] The pump body 19 has an interconnected air chamber 23 and an adsorption chamber 26 at its upper and lower ends. The adsorption chamber 26 has a Venturi tube configuration. The pressure rod 16 is movably connected to the pump body 19, with its lower end connected to a piston 22 located in the air chamber 23 and its upper end connected to a hand-operated device 15. One end of the water intake pipe 20 is connected to the adsorption chamber 26, and the other end is located inside the tank 1. One end of the air-water mixing pipe 25 is connected to the bottom outlet of the adsorption chamber 26, and the other end is connected to the inlet end of the conduit 4. The outlet end of the conduit 4 is connected to the toilet bowl 27 through the nozzle 5. One end of the return spring 21 is connected to the pressure rod 16, and the other end is connected to the pump body 19, for resetting the pressure rod 16.

[0030] The nozzle 5 has an arc-shaped head. A rectangular water outlet 6 is provided on one side of the nozzle 5 head. A nozzle sealing ring 7 is provided at the upper end of the rectangular water outlet 6. A reinforcing rib 9 is provided on the side wall of the connection area 8 on the nozzle 5. The nozzle 5 is connected to the toilet bowl 27 through the nozzle sealing ring 7.

[0031] Preferably, the cross-sectional area of ​​the lower end of the gas chamber 23 gradually decreases from top to bottom, forming a funnel shape. The lower end of the adsorption chamber 26 is connected to the gas-water mixing pipe 25 by a sealing bolt 24. The gas-water mixing pipe 25 and the conduit 4 are connected by a conduit sealing ring 3, which is set on the barrel body 1.

[0032] The specific working process and principle of the above embodiments are as follows:

[0033] During installation, the bucket 1 does not need to be buried in the ground and can be placed around the toilet 27 according to the farmer's wishes, which greatly reduces the cost and difficulty of modification or construction and installation.

[0034] When in use, the cross beam 11 has four fan-shaped water inlets 10 around it. The water inlets 10 can be connected to the drain pipe of the washbasin, or they can be manually filled with gray water generated from bathing, washing, etc. Normally, they are covered by four fan-shaped plastic caps to prevent foreign objects from entering the inside of the bucket 1 and clogging the pipes.

[0035] The cross beam 11 at the top of the lid 2 is provided with an opening and a fixing seat 12. The gas-water mixing pump is fixed to the cross beam 11 by these components, plastic bolts, brackets 17, etc., which can effectively prevent the pump body 19 from shaking during use.

[0036] The air-water mixing pump utilizes the Venturi effect. By pressing down on the hand-operated pump 15, the pressure rod 16 and rubber piston 22 compress the air in the air chamber 23 into the adsorption chamber 26. As the cross-section of the air gradually decreases, the pressure of the compressed air drops sharply, and the flow rate increases. At this point, a vacuum is created at the connection between the adsorption chamber 26 and the water pipe 20, causing the liquid in the bucket 1 to be drawn into the adsorption chamber 26 and mixed with the compressed air, flowing into the air-water mixing pipe 25 to form an air-water mixture. This mixture is then sprayed into the toilet bowl 27 through the conduit 4 and nozzle 5. Due to the intervention of high-pressure air, compared to traditional water-saving high-pressure flushers, this invention not only uses very little water (0.2-0.3 liters / flush) but also improves cleaning efficiency.

[0037] After the hand pressure device 15 is released, the pressure rod 16, under the action of the return spring 21, drives the piston 22 to return to its original position, and the air chamber 23 is filled with gas again, waiting for the next flushing operation.

[0038] A steel wire conduit 4 is installed on the outer bottom of the tub body 1, which is sealed to the tub body 1. A nozzle 5 is installed at the end of the conduit 4, which can be connected to the water inlet of the toilet bowl 27. The nozzle 5 has an arc-shaped head, and a rectangular water outlet 6 is provided on one side of the nozzle head. The design of the rectangular water outlet 6 can spray water out in a fan shape, with a large water flow impact force and a large washing area. A nozzle sealing ring 7 is provided at the upper end of the rectangular water outlet 6, and a reinforcing rib 9 is provided on the side wall of the connection area 8 on the nozzle 5, which can seal and firmly fix the nozzle 5 to the interface of the toilet bowl 27.

[0039] The above specific embodiments are only for illustrating the technical concept and structural features of the present invention, and are intended to enable those skilled in the art to implement them. However, the above content does not limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit and essence of the present invention should fall within the scope of protection of the present invention.
