Description

Technical Field

[0001] The present invention relates to sanitary ware, in particular to a water-free toilet Background Art

[0002] The existing toilets and squat toilets are equipped with a water return bend on the downpipe. The water return bend can use the siphon principle to bring the feces and sewage in the toilet into the sewer and has the function of blocking the odor in the sewer. The defects are:

[0003] 1. In the backwater bend structure, if the feces and sewage are floating objects or long strips, they are not easily sucked into the backwater bend. They need to be flushed repeatedly to disperse the feces and sewage with water and can only be sent into the sewer under strong impact. This is very water-consuming and embarrassing.

[0004] 2. The water stored in the return bend forms puddles at the bottom of toilets and squat toilets. When using the toilet, feces and sewage will fall into the puddles and splash into the water, contaminating the human body and the inner wall of the toilet. This is unhygienic to use, especially in public toilets, as it is prone to cross infection.

[0005] 3. When using traditional toilets and squat toilets, if you forget to flush them, feces and sewage will always accumulate in puddles, which will have a strong smell. Although there are ventilation devices in the toilet to continuously absorb the odor in the toilet, the ventilation devices are usually installed on the top of the toilet. In the presence of feces and sewage, toilet users will always breathe air with odor, and the odor removal effect is not significant.

[0006] 4. Toilets and squat toilets with a backwater bend structure require more water to flush the dirt on the inner wall of the toilet and squat toilet due to the splashing and accumulation of feces and sewage. A certain amount of water is needed to pull the feces and sewage into the backwater bend, and the feces and sewage can be sucked into the sewer after siphoning. The water flow needs to be closed from large to small so that a certain amount of water remains in the backwater bend to block the odor in the sewer. The entire use process is very water-consuming.

[0007] 5. Traditional toilets are equipped with water tanks, which will produce odor and bacteria if not used for a few days. It is difficult to clean thoroughly even after a few times of use. In order to meet the technical requirements of the industry, many businesses set two levels of drain buttons under the guise of water-saving. One of them is to deceive people by fictitious idle positions.

[0008] 6. When traditional toilets and squat toilets are not used for a long time, the water in the return bend will evaporate and dry up over time. At this time, the return bend will lose its odor-blocking function and become unhygienic.

[0009] 7. Traditional toilets only have two front and rear adjustment ports at the bottom, which cannot meet the needs of left and right movement.

[0010] 8. The foot pedal of a traditional squat toilet can be moved freely forward and backward, and feces and dirt often fall out of the toilet bowl, which is not only unhygienic but also wastes cleaning water, thus wasting unnecessary time.

[0011] 9. This technology is based on the previous invention patent of "A Toilet", and further improves and optimizes the closing structure, spray structure, deodorization structure, fan and nozzle switch structure, toilet bowl human buttocks shape and squatting shape structure.

[0012] 10. What is even more gratifying is that this technology can transform existing toilets into flush-free toilets, saving manpower, money, materials, time and space to achieve five major functions: ultra-water saving, separation of feces and sewage, environmental protection without flowing into rivers, lakes and reservoirs, epidemic prevention at the toilet and mouth, and low-carbon emission reduction. Summary of the invention

[0013] The purpose of the present invention is to provide a water-free toilet which uses only 0.1 liter of water and is extremely water-saving. It operates under negative pressure and does not emit germs or odors, so it can prevent epidemics, be hygienic and healthy. Feces and sewage will not flow into rivers, lakes or reservoirs, which is environmentally friendly. Feces and sewage are purely separated from the grain cycle, and feces and sewage are recycled as resources for sustainable development.

[0014] The technical solution of the present invention is a water-free toilet, comprising a toilet bowl, the upper opening of which is provided with a seat ring, and is characterized in that:

[0015] 1) The contour and shape of the seat ring highly imitate the buttocks of human body science, so that the anus and the drain outlet are nearly vertical and within a few centimeters. The seat ring is covered with a toilet bowl cover, and the rear end of the toilet bowl cover is hinged to the column through a hinge shaft.

[0016] 2) The squat toilet has a fixed foot pedal position, which highly imitates the scientific squatting posture of the human body. The anus and the drain outlet are nearly vertical and the distance between them is within a few centimeters. There are nozzles in front and behind the toilet bowl, and an air suction port at the rear of the toilet bowl.

[0017] 3) An air suction port is provided between the upper side of the drain outlet of the toilet bowl and the seat ring. The sucked air is sent out through the ventilation pipe or sewer. A cleaning nozzle is fixed on the lower part of the front and back of the seat ring. The operation of the fan and the cleaning nozzle is controlled by three switching modes: induction, voice or manual.

[0018] 4) The toilet bowl is provided with a water outlet, a closing switch is provided at the lower end of the water outlet, and a filter net bag is provided under the switch, which is characterized by:

[0019] (1) When feces and sewage fall, it opens under the action of gravity. After the feces and sewage pass through, it automatically closes under the action of gravity, magnetism and springs to prevent the odor from returning. (2) There is a water supply pipe outside the downspout, the upper part is closed under the toilet bowl, and the lower part is connected to the flange closing switch, which plays the role of safely sending feces and sewage into the sewer between the two closing switches.

[0020] 5) A flange closing switch is provided at the bottom of the water supply pipe to connect with the sewer. The features include: (1) a tight connection between the water supply pipe and the sewer, and (2) the first line of defense to prevent the odor from the sewer from coming back up. This double barrier to odor is achieved together with the closing switch of the downspout.

[0021] The seat ring shape and the toilet bowl of the sitting toilet and the toilet bowl of the squatting toilet highly imitate the buttocks shape and squatting posture shape of the human body science. When a person sits down, the anus and the drain outlet are nearly vertical and the distance is within a few centimeters. If the person sits down or squats slightly to the side, because the distance from the anus to the drain outlet is only a few centimeters, and the drain outlet area is 29.83 centimeters, which is more than 3 times the maximum expansion area of ​​the anus, feces and sewage can fall into the sewer within seconds by their own weight without any worries. In addition, the slopes of the three sides of the toilet bowl are nearly vertical, and the feces and sewage will automatically slide down and be quickly sent out to the water pipe outside the closed switch, so as to avoid the feces and sewage staying in the toilet bowl until the end of defecation and releasing odor and bacteria.

[0022] The two cleaning nozzles are respectively arranged and fixed under the seat rings on the front and rear sides of the toilet bowl. The front nozzle water distribution pipe is fixed under the seat ring along the seat ring. The front and rear water distribution pipes are connected with the main water pipe at the 3-way position of the column fixed axis. In fact, after defecation, almost no feces and sewage can be seen in the toilet bowl. This is the core of the technology. If feces and sewage remain in the toilet bowl due to incorrect sitting posture or diarrhea, the toilet bowl can be cleaned by spraying a few times with a spare spray gun. The nozzle is a commercially available sprayer head, and the water supply pipe and connecting tee are commercially available air pump related products. The spare spray gun and water pipe are commercially available air pump spiral tubes, which are convenient and retractable, safe, durable and reliable.

[0023] The two cleaning nozzles are installed in the toilet bowl on the front and rear sides of the squat toilet, and the water supply pipe is invisible in the squat toilet structure. In fact, the core of this technology is that after defecation, almost no feces and sewage can be seen in the toilet bowl. If feces and sewage remain in the toilet bowl due to incorrect squatting posture or diarrhea, the toilet bowl can be cleaned by spraying a few times with a prepared spray gun. The water source of the spray gun is the city water supply, and the pressure is sufficient without pressurization. If there is no water supply, a small circulation pump can be installed.

[0024] The air suction port is arranged between the toilet bowl and the seat ring on one side of the drain outlet, and the fan is fixed under the toilet bowl. The operation of the fan and the cleaning nozzle is switched on and off by induction, voice or manual mode. Since the human body completely covers the seat ring, all the odors and germs generated when using the toilet are sucked out and sent out through the ventilation pipe or sewer.

[0025] The squat toilet air suction port is arranged on one side of the drain outlet. The squat toilet is different from the traditional squat toilet. Its shape and outline highly imitate the squatting posture of the human body. It reduces the entry of outside air when using the toilet, improves the air suction port to suck out odors and germs in the toilet bowl, and the fan and the cleaning nozzle are turned on and off by induction, voice or manual.

[0026] The operating principle of the closing switch under the drain outlet is gravity, magnetism and spring action. When feces and sewage fall, the baffle is pushed open by gravity. After the feces and sewage pass through, the baffle is automatically closed immediately. This function avoids backflow and rat invasion when the sewer is blocked.

[0027] The filter net bag is arranged below the closing switch and is fixed on a hook in the water supply pipe. It is characterized by being made of metal, nylon, fiber and other fine filaments, which can quickly cut the feces and sewage that should fall and send them smoothly to the sewer, and completely intercept other objects that should not fall. The bag shape can retain objects that cannot be cut immediately, thereby avoiding the phenomenon that objects such as toilet paper cannot be cut immediately and block the filter net, causing feces and sewage to be delivered unobstructed.

[0028] The flange closing switch is a connecting component between the sewer outlet and the lower section of the toilet water supply pipe. It is a double measure to prevent sewer odor. In this way, the area of ​​more than ten centimeters between the flange closing switch and the upper drain outlet is doubly closed, and the lack of air flow further prevents odor, with excellent results.

[0029] The universal distance adjuster is used to solve the problem that the bottom of a traditional toilet has only two front and rear distance adjustment openings, which cannot meet the need for left and right movement.

[0030] The fixed squat toilet foot pedal is to avoid the phenomenon that the foot pedal of the squat toilet is free in the past, and the feces and sewage will inevitably fall out of the toilet bowl in an emergency. It avoids the unsanitary phenomenon that the stool or urine always exceeds the toilet bowl in the past squat toilet, which brings discomfort to cleaning and makes it difficult for the lower toilet user to start.

[0031] The spare spray gun is based on the actual needs of the toilet obtained from public opinion surveys, and is an effective measure to quickly eliminate feces and dirt when diarrhea or incorrect sitting or squatting postures leave feces and dirt traces in the toilet bowl, and to save water and clean the toilet bowl.

[0032] The push toilet can be transformed into a waterless toilet when the user does not want to replace the existing toilet. It is necessary to change the previous water flushing to a certain amount of feces and sewage and use the push toilet to deliver the feces and sewage, so as to achieve water-free separation and ensure the closed switch of the drain outlet.

[0033] Advantages of the present invention

[0034] 1. When using the toilet, the person sits in the toilet and the fan is activated by induction, voice or manual. At this time, the air in the toilet produces a pressure difference, and the air in the toilet moves toward the air suction port. When people use the toilet, most of the toilet slots are blocked by the human body. The fan sucks the air out of the toilet, preventing odors and germs from moving into the toilet space or overflowing during the process of using the toilet. Since the area of ​​the water outlet is 29.83 cm, which is 3 times the maximum expansion area of ​​the anus, the feces and sewage fall into the sewer within seconds by their own weight without worry. Since there are no puddles, no entry is generated. The splashing phenomenon is hygienic to use. It can not only eliminate the odor from the source and reduce odor pollution, but also has a significant effect on removing odor under the action of the fan, which can make users feel comfortable breathing. The feces and sewage fall directly into the sewer from the anus within seconds, which has less pollution to the toilet bowl. After defecation, only a small amount of water is needed to spray the closed switch baffle. It is easy to clean and saves water, ensuring that the odor is discharged cleanly and preventing the back-odor. The closing switch of the drain outlet always remains sealed when there is no falling feces and sewage, which will not cause the sewer odor to return. It also has the function of preventing rat invasion and preventing the sewer from being blocked by feces and sewage.

[0035] 2. The net bag type filter, which is arranged under the closing switch of the drain outlet, is in the form of a net bag woven with metal, nylon, fiber and other fine filaments. First, the gravity of feces and sewage is utilized, and the filter pre-cuts large pieces of feces and sewage to help them enter the sewer more smoothly to avoid blockage of the sewer. Second, it can prevent valuables such as mobile phones, watches, keys, wallets, etc. from falling into the sewer and causing losses. Third, large pieces of materials that are not easily soluble in water, such as toilet paper, are first intercepted and temporarily piled at the bottom of the net bag. They are naturally cut and decomposed and released under the influence of the continuously falling feces and sewage. Because a large space is left on the upper part of the bag, which does not hinder the falling and cutting of feces and sewage, the structure is particularly suitable for use in public places.

[0036] 3. When the selected material is a light-weight resin, the hollow part can be easily transported, carried and installed. The duck claw glue at the bottom skirt of the column extends inward to improve stability and resist the lateral thrust on the toilet when the human body leans down to sit. At the same time, the fan can be stably hidden in the edge of the group, reducing the erosion and influence of water vapor in the toilet on the fan, thereby increasing the service life of the fan and reducing noise.

[0037] 4. When a person sits in the toilet, the sensor or voice or manual start the fan, which continuously sucks the air in the toilet bowl from the air intake port and sends it out through the ventilation pipe. Because the toilet bowl opening is covered by the sitting posture, negative pressure is generated in the toilet bowl, and the odor and bacteria in the feces and sewage cannot escape from the toilet bowl, and cannot spread to the toilet space to pollute the air in the toilet. In addition, this technology is different from traditional toilets. Feces and sewage fall into the sewer within seconds, and the odor is completely removed by closing the switch.

[0038] 5. When a person enters the squat toilet, the sensor or voice or manual fan is started, and the air in the toilet bowl is continuously sucked away from the air suction port and sent out through the ventilation pipe. Because the squat toilet highly imitates the human body squatting posture, the air outlet is better blocked. In addition, the air suction port is around the feces drop. Although it is not as tightly covered as a toilet, the strong suction force creates negative pressure in the toilet bowl, and the odor and bacteria have no chance to spread to the toilet space. In addition, this technology is different from the traditional squat toilet. The anus is only a few centimeters away from the drain outlet, and the feces and sewage will not accumulate and fall into the sewer within seconds. The closed switch is tight to remove odors thoroughly.

[0039] 6. The toilet and squat toilet of this technology have compact structure and each component is responsive and moves quickly. The tail of the long stool has not come out of the anus and the closed baffle has been opened to enter the water supply pipe, like a loach actively finding the sewer. Therefore, 99% of people can't see the traces of feces accumulation in the toilet bowl after defecation. The so-called spray cleaning is just a form and habit. If there is a possibility of feces and dirt left in the toilet bowl during diarrhea, the toilet bowl can be cleaned by spraying a few times with the prepared spray gun.

[0040] 7. The flange closing switch is the second core of the technology of the present invention. It is a connecting component between the sewer outlet and the lower section of the toilet water supply pipe. It is a double measure to prevent the sewer odor. In this way, there is only a dozen centimeters between the upper drain outlet closing switch and the double closure. The lack of air flow further prevents the odor from returning, and the effect is excellent.

[0041] 8. The universal distance adjuster is used to solve the problem that the traditional toilet has only two front and rear distance adjustment ports at the bottom, which cannot meet the need for left and right movement.

[0042] 9. Install a spare spray gun. When diarrhea or incorrect sitting or squatting posture leaves traces of feces in the toilet bowl, use the prepared spray gun to immediately remove them to ensure the toilet bowl is clean.

[0043] 10. Fixed foot pedal. No matter the height, age or squatting posture, the fixed foot pedal makes the anus and the drain outlet close to vertical, which helps the feces and sewage fall into the sewer quickly. It avoids the unsanitary phenomenon of squatting toilets in the past where either defecation or urination always exceeds the toilet bowl, which brings discomfort to cleaning and makes it difficult for the squatting user to start.

[0044] 11. Push toilet, even if you don't want to change the toilet, you can use this technology to transform the water-free toilet. Install the toilet trough of this technology on the original toilet, and install a push toilet at the outlet below. You need to change the previous flushing with water to a certain amount of feces and sewage and use the push toilet to send out the feces and sewage, so as to save water and separate the feces and sewage, and ensure the closing and switching of the water outlet.

[0058] Waterless toilets, such as Figures 1 to 12 , a toilet column 1 is provided with a toilet trough 2, a seat ring 4 is provided on the toilet trough, a toilet trough cover 9 is provided on the seat ring, and the seat ring 4 and the toilet trough cover 9 are hinged to the toilet column 1 at the rear end by a relatively large shaft 10; a water outlet 3 is provided at the bottom rear side of the toilet trough 2, a closing switch fixing seat 11 is glued to the water outlet 3, a filter net bag 14 is provided below the closing switch, and is fixed to the inner wall of a downpipe 16 by a hook 15. The upper part of the downpipe 16 is fixed to the bottom of the toilet trough 2, and the lower part is fixed to the sewer 21 by a flange closing switch 17, and the water outlet closing switch 11 and the filter net bag 14 are all surrounded in the downpipe 16; anything on the toilet trough 2 is concentrated to the water outlet 3, the closing baffle 12 is pushed open by gravity, and then directly falls into the sewer 21 through the flange closing baffle 19 after being cut by the filter net bag 14, and the material that cannot be cut is suspended at the bottom of the filter net bag 14, and is naturally decomposed and cut into the sewer over time, or the material that cannot be cut is taken out manually.

[0059] The closing switches 12, 19 are one-way valves that only allow objects to fall. When the sewer is blocked, the closing function completely prevents the overflow of feces and sewage and also prevents rats from invading.

[0060] The filter net bag 14 is hollow at the upper edge of the filter and is hung on the net bag hook 15 on the inner wall of the downpipe 16. The filter material is woven from metal, nylon, fiber and other filaments, with a mesh size of 2-3 cm. It is easy to cut and durable. The net bag hook 15 is fixed on the inner wall of the downpipe 16 at the closed switch position. If it needs to be replaced, use a tool to hook out the old net bag and replace it with a new one.

[0061] The upper opening of the downpipe 16 is fixedly linked to the toilet trough 2, and the lower opening is fixedly linked to the sewer 21 with a flange closing switch 17.

[0062] like Figure 8 The height of the toilet bowl is designed to imitate the falling shape of feces and urine when using the toilet. It can not only drop the feces and sewage accurately, but also realize the precise and reasonable spatial design, so that the clean area of ​​the toilet bowl 2 after defecation is minimized to achieve the purpose of water saving and environmental protection, and also highly optimize the ornamental appearance of the toilet bowl 2.

[0063] like Figure 8 The seat ring 4 is designed to highly imitate the scientific sitting posture of the human body. It is comfortable to sit on, and the anus and the drain outlet 3 are nearly vertical and only a few centimeters apart, so that feces and sewage can fall into the sewer 21 faster and more accurately, reducing the adhesion or hanging of feces and sewage on the toilet bowl 2, and avoiding unnecessary flushing waste.

[0064] like Figure 2 The nozzles 5 arranged before and after the toilet bowl 2 are commercially available products. Before opening the toilet bowl cover 9 and sitting down, the manual water supply switch 23 nozzle 5 sprays water once to wet the toilet bowl 2 so that feces and sewage can fall more smoothly, reduce the adhesion or hanging of feces and sewage on the toilet bowl 2, and avoid flushing to achieve the purpose of saving water. After using the toilet, the manual water supply switch 23 nozzle 5 pauses to spray water three times to clean the toilet bowl 2. In this way, the three pauses in water output can increase the pressure, which is greater than the continuous water output pressure and has a better effect, and the best cleaning effect can be achieved with the same amount of water.

[0065] like Figure 8 The air suction port is used to start the manual fan 30 before a person sits down to suck away the air in the toilet bowl 2 including odors and germs, and the air enters the fan air inlet 26. The fan air outlet 27 then sends the air to the air supply pipe or the sewer column pipe 28 on the wall. After the toilet is finished, the manual swing lever 30 stops the fan 27.

[0066] like Figure 4 The manual push-button switch 23 is a commercially available product, fixed on the wall behind the toilet, and is used for the water discharge command of the sprinkler. The push-button switch 23 is convenient for commanding water discharge and water stop more sensitively to achieve the purpose of saving water.

[0067] like Figure 5 The manual swing switch 30 is a commercially available product, fixed on the wall behind the toilet, and is used for starting and stopping instructions of the fan. The swing switch 30 has stable instruction performance.

[0068] The electronic version, the induction or voice receiver 36 is fixed on the front part of the toilet, the control panel 37 is placed inside or behind the toilet, and the circuits are all installed in a hidden manner, and can automatically operate according to the actions of the toilet user or timely shouting as needed.

[0069] The squat toilet is as follows Fig. 9 ,like Fig. 9The toilet bowl 2 highly imitates the scientific squatting posture of the human body, and is designed in the falling shape of urine and feces when using the toilet. The position of the foot pedal 31 is accurately fixed, which can not only make the feces and sewage fall more quickly and accurately to avoid leaving traces of feces and sewage in the toilet bowl 2, but also is the precise and reasonable spatial design, so that the cleaning area of ​​the toilet bowl 2 after defecation is minimized to achieve the purpose of water saving and environmental protection, and also highly optimize the ornamental value of the toilet bowl 2.

[0070] The flange closing switch 17 is first installed in the sewer 21 when installing the toilet, and then the toilet is aligned with the opening 17 and lowered steadily, and the toilet is gently pressed down, and a circle of glue is applied to the bottom of the toilet where it contacts the ground to fix it.

[0071] like Fig.11 The universal distance adjuster is used to solve the problem that the traditional toilet has only two front and rear distance adjustment ports at the bottom, which cannot meet the need for left and right movement. When distance adjustment is required, first insert the sewer port 33 into the sewer 21, then move the rotatable tube 35, adjust the toilet port 34 to the desired position, and then align the toilet with the toilet port 34 and put it down.

[0072] like Fig.10 The duck claw is formed by extending the bottom of the skirt inward in the shape of a duck claw in order to further stabilize the toilet made of light materials such as resin. Since the duck claw 32 is adhered to the ground over a large area, the adhesive surface is expanded to make the installation more secure.

[0073] The spare spray gun is a commercially available product, which is usually hung on the wall behind the toilet for use. Once heavy feces and dirt are found, it can be picked up and sprayed in a focused manner. It is a supplementary measure that can clean the toilet trough 2 better and more timely, which is convenient, applicable, hygienic, economical, water-saving and durable.

[0074] The water supply filter 38 is arranged on the water supply pipe 24 in front of the electromagnetic valve to prevent particles from mixing in and clogging the nozzle and affecting the cleanliness of the toilet bowl.

[0075] like Fig.12 As described above, when an old toilet is transformed into a flush-free toilet with this technology, after the toilet trough of this technology is installed on the toilet, the toilet delivery bucket 39 is set at the S-bend entrance of the old toilet, and the push-pull handle 46 is hung on the wall. The purpose is to wait until a certain amount of feces and sewage accumulates to hinder the operation of the drain outlet closing switch, hold the push-pull handle 46, pull the rope 45, and under the action of tension, close the feces outlet baffle 41, open the feces inlet 42 to let feces in, relax the push-pull handle 46, close the feces inlet baffle 43, and open the feces outlet 40 under the action of the push spring 44 to deliver the feces and sewage in the toilet delivery bucket 39. Repeating this operation several times can complete the defecation, which is simple, economical, water-saving and easy to use.

[0076] like Figure 1 As described above, the signal of the induction or voice receiver 36 is wirelessly transmitted to the control board 37 , and the control board 37 then instructs the fan 26 and the solenoid valve 49 to work through the electric control line 50 .
