Description

Technical Field

[0001] This invention relates to the field of sanitary ware technology, and in particular to an automatic odor-blocking, water-retaining, and freeze-proof toilet. Background Art

[0002] Currently, the rural toilet revolution is in full swing across the country. According to the requirements for toilet renovation, the renovated toilets should meet the "three-fold" standard: underground harmlessness, above-ground hygiene, and ease of use. This means the toilets should be clean and free of flies and insects, convenient to use and able to withstand winter, and odorless. Currently, traditional squat (or seated) toilets are used in urban areas where infrastructure is well-developed, water sources are plentiful for flushing, and toilets have good insulation, thus addressing hygiene, odor control, frost prevention, and ease of use to a reasonable extent. However, when introduced into rural environments, due to poor infrastructure, inadequate toilet insulation, and untimely water supply, the unsuitability of traditional squat (or seated) toilets is becoming increasingly apparent. It has been found that the odor-proofing and frost-proofing functions of traditional toilets contradict each other with the passage of feces. Toilets with good odor-proofing and frost-proofing functions experience severe freezing in winter, affecting normal use; while toilets with good fecal passage have poor odor control in summer due to open drains, resulting in severe odors and increased susceptibility to disease transmission due to contact between flies and feces. These phenomena are particularly prominent in the cold and water-scarce regions of northern my country. The sanitation problems after rural toilet renovations have not been fundamentally solved, and problems such as inconvenience in winter use have arisen. This is a major reason for the low public satisfaction with the rural toilet revolution. Solving the problems of odor prevention, hygiene, and winter frost protection in rural toilets has become the biggest challenge currently hindering the toilet revolution.

[0003] Existing squat toilets (and seated toilets) typically have a large water tank and an S-bend seal at the back, requiring high levels of insulation and reliable water supply. Rural toilets are generally rudimentary, with poor insulation and unreliable water supply. In most rural areas of northern my country, the S-bend seal and water tank are prone to freezing during winter, rendering them unusable or exposing waste. Furthermore, existing squat toilets have a straight discharge outlet; even with odor-proof valves, their odor-proofing and fly-proofing effects are poor, resulting in strong odors and swarms of flies in rural toilets during the summer.

[0004] Existing toilets, whether siphon or direct flush, all have curved drain pipes that use water level differences to trap odors. To allow waste to pass smoothly through the horizontal S-shaped pipe, a large amount of water is required, generally at least 4 to 6 liters. Even when flushing urine, nearly a tank of water is needed, resulting in significant water waste.

[0005] Existing squat toilets (or seated toilets) emit unpleasant odors during use. Since the toilets lack ventilation devices, they cannot eliminate odors and moisture, requiring the installation of an additional ventilation fan.

[0006] After use, existing squat (seat) toilets often leave solid excrement residue at the outlet of the toilet and on the walls of the bowl. This is especially true in public places, where the residue tends to accumulate over time, making them extremely unhygienic. Flushing with water requires a large amount of water, and cleaning by a dedicated person is a waste of manpower.

[0007] Most existing squat toilets (and seated toilets) are made of ceramic, which has a complex structure and high material requirements. This not only results in high production costs but also consumes a lot of energy during the firing process, failing to meet national energy conservation and emission reduction requirements. Furthermore, their bulky and fragile nature makes transportation difficult. For all-stainless steel toilets, the high production cost hinders widespread adoption. As for all-plastic toilets, their easily scratched surface and inherent lack of smoothness increase the difficulty of cleaning, leading to low public acceptance.

[0008] Existing squat toilets (and seated toilets) with flap-type sealing functions also have many hygiene problems. Due to their internal structure, direct contact between feces and the flap cannot be avoided, and residual feces are easily exposed and cause pollution. Some have a coating on the flap to increase its stain resistance, but this technical solution has limited effectiveness. Not only is the coating cost high, but it is also very easy to scratch, and the stain resistance will decrease with prolonged use. Summary of the Invention

[0009] The technical problem this invention aims to solve is to provide an automatic odor-blocking, micro-water, and antifreeze toilet that instantly isolates feces from the outside environment during and after use. By modifying the internal cavity structure of the toilet, feces have minimal or no contact with the bowl and tilting mechanism, thus achieving a micro-water flushing effect. Furthermore, by changing the sealing method, the gas barrier effect is improved, and antifreeze functionality is achieved. This significantly enhances toilet hygiene, preventing flies and insects from contacting feces, thereby reducing disease transmission routes. The toilet's internal transmission structure is simple and reliable, improving the overall device's lifespan. The toilet employs dual micro-water flushing and dual micro-water sealing technology, enhancing its adaptability to various environments. It simultaneously improves gas isolation, effectively isolates odors, reduces costs, and is inexpensive, making it easy to promote; it reduces the amount of water used for flushing, saves water, effectively prevents sewage splashing, improves flushing effect, reduces fecal residue and adhesion, reduces pollution to the toilet environment, and prevents fecal contamination of users; all parts are detachable, making installation and use convenient and maintenance easy; it improves user comfort; and it helps to achieve clean toilets, free of flies and maggots, and virtually odorless.

[0010] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0011] An automatic odor-proof, water-saving, and freeze-proof toilet includes a toilet shell, a seat ring, a toilet bowl, and a toilet lid. It also includes a push-button flap hinged to the bottom edge of the toilet bowl for sealing the lower opening of the toilet bowl. The push-button flap opens under the drive of a push-button flap drive mechanism, which engages the seat ring to achieve the action. The push-button flap is reset by a push-button flap reset mechanism to achieve a seal.

[0012] A further improvement of the technical solution of the present invention is that: the pressing flip plate driving mechanism includes a horizontal shaft fixedly connected to the pressing flip plate and coaxially arranged with the hinge rotation axis of the pressing flip plate, a rocker arm fixedly connected to the end of the horizontal shaft and perpendicular to the horizontal shaft, a pressure rod provided at the upper end of the rocker arm and pressed on the rocker arm at the lower end, which slides vertically under the swinging and locking action of the seat ring, and the pressure rod is fixedly connected to a pressure rod elastic pulling device.

[0013] A further improvement of the technical solution of the present invention is that: the pressure rod is vertically sleeved in the vertical sliding groove on the toilet seat shell, the upper end of the pressure rod is in contact with the lower surface of the seat ring, the lower end of the pressure rod is arc-shaped, and the end of the rocker arm is provided with a groove that matches the lower end of the pressure rod.

[0014] A further improvement of the technical solution of the present invention is that the pressing flip plate reset mechanism is a pressing weight fixedly connected to the hinge end of the pressing flip plate or a torsion spring sleeved on the hinge shaft of the pressing flip plate.

[0015] A further improvement of the technical solution of the present invention is that when the pressing flap is opened under the drive of the pressing flap driving mechanism, the flip angle of the pressing flap is greater than or equal to 90°.

[0016] A further improvement of the technical solution of the present invention is that: the height of the toilet bowl does not exceed 15 cm, and the minimum distance between the lower opening of the toilet bowl and the rear surface of the toilet seat is less than the minimum distance between the inner opening of the seat ring and the rear surface of the toilet seat.

[0017] A further improvement of the technical solution of the present invention is that: an air-tight chamber is provided below the toilet bowl, and an automatic flap is hinged to the lower opening of the air-tight chamber, and an automatic flap counterweight is fixedly connected to the hinged end of the automatic flap.

[0018] A further improvement of the technical solution of the present invention is that the edges of the pressing flip plate and the automatic flip plate are provided with upward-turning flanges.

[0019] A further improvement of the technical solution of the present invention is that it also includes a flushing system with water outlets respectively set on the side walls of the toilet bowl and the air-tight chamber, and water outlets with water outlets on both sides forming a ring spray are fixedly connected to the water outlets of the flushing system.

[0020] A further improvement of the technical solution of the present invention is that: a seat ring inner pad is fixedly connected to the upper surface of the toilet seat shell, wherein the seat ring is a shell whose inner cavity is adapted to the shape of the seat ring inner pad.

[0021] The technological advancements achieved by this invention due to the adoption of the above technical solutions are as follows:

[0022] This invention provides immediate and complete isolation of feces from the outside environment during and after use, preventing the turning mechanism from contacting the feces and thus avoiding contamination and corrosion. It also prevents flies and insects from coming into contact with the feces, thus preventing their breeding. Simultaneously, it improves gas isolation, effectively blocking odors. The simple and reliable structure is less prone to failure, enhancing the overall device's adaptability to various environments and extending its service life. It reduces costs, making it inexpensive and easy to promote. It reduces the amount of water used for flushing, saving water and effectively preventing sewage splashing, improving flushing efficiency. It also reduces fecal residue and adhesion on the toilet bowl walls, improving the toilet's hygiene and reducing pollution of the toilet environment, preventing fecal contamination of users. All parts are detachable, making installation and use convenient and maintenance easy. It improves user comfort and contributes to a clean, fly- and maggot-free, and virtually odorless toilet, while also improving its anti-freezing capabilities.

[0023] The flip-top design is simple and reliable, and while improving the gas barrier effect, it can effectively solve the problem of ice formation affecting toilet use in winter.

[0024] When the pressing flap is opened under the drive of the pressing flap drive mechanism, the pressing flap flips at an angle greater than or equal to 90°, which reduces the space occupied by the pressing weight and expands the range of angles that the pressing flap can flip, allowing the pressing flap to flip more than 90°, thus avoiding direct contact between the pressing flap and the feces.

[0025] The automatic flip-plate reset mechanism automatically activates the flip-plate. The height of the toilet bowl is no more than 15 centimeters. The minimum distance between the lower opening of the toilet bowl and the rear surface of the toilet bowl is less than the minimum distance between the inner opening of the seat ring and the rear surface of the toilet bowl. These dimensional limitations ensure that feces are aligned with the lower outlet of the toilet bowl, reducing the chance of feces splashing, reducing feces adhering to the toilet bowl, reducing pollution to the toilet environment, and facilitating toilet bowl cleaning.

[0026] The air-tight chamber located below the toilet bowl helps to isolate gas below the bowl, while also creating a hollow structure inside the toilet, making it easy to install other deodorizing devices. It also allows fecal matter to flow out directly from the two openings, preventing fecal matter from splashing in the space between the air-tight chamber and the bowl, thus reducing the burden of cleaning.

[0027] Pressing the flap and the automatic flap lifts the edges upwards, which helps to catch a small amount of flushing water. The water and the flap work together so that when the two flaps return to the horizontal position, the water fills the gap between the flap and the lower opening of the air-sealing chamber and the lower opening of the toilet bowl, creating a double-layered gas-isolating structure and improving the odor-proofing effect.

[0028] A flushing system with water inlets located on the side walls of both the toilet bowl and the vent chamber allows for simultaneous cleaning of both. This dual flushing system fully utilizes water pressure, ensuring thorough cleaning of both the toilet bowl and the vent chamber at the same time. This prevents water from flowing down from the top layer and causing insufficient water pressure, which could result in ineffective flushing and prevent fecal matter from adhering to the side walls of the toilet bowl and the vent chamber.

[0029] The seat's structure limits the user's position, making it easy to direct feces towards the lower outlet of the toilet bowl. This avoids contact between the toilet bowl and the side walls of the vent chamber and feces, reducing feces adhering to the toilet bowl, minimizing pollution to the toilet environment, and lowering the requirements for cleaning.

[0030] The inner seat pad is fixedly connected to the upper surface of the toilet bowl housing. The toilet bowl itself is a shell whose inner cavity conforms to the shape of the inner seat pad, preventing seat misalignment. This helps to define the user's position and direct waste towards the lower outlet of the toilet bowl, avoiding structural damage caused by seat misalignment and extending the lifespan of the toilet bowl. The inner seat pad also securely connects the toilet bowl to the toilet bowl housing, facilitating toilet bowl stability and providing a fixing point for the push-to-open mechanism.

[0035] The present invention will be further described in detail below with reference to embodiments:

[0036] like Figure 1 , Figure 2 and Figure 3As shown, an automatic odor-proof, water-saving, and freeze-proof toilet includes a toilet shell 1, a seat ring 2, a toilet bowl 4, and a toilet lid 3. It also includes a push-button flap 6a and a push-button flap driving mechanism. The toilet shell 1 is made of stainless steel, the seat ring 2 is a hollow shell, and the push-button flap 6a is hinged to the lower opening of the toilet bowl 4. The push-button flap driving mechanism opens the lower opening of the toilet bowl 4 by rotating the hinge shaft of the push-button flap 6a. It includes a horizontal shaft 6e, a rocker arm 6f, a pressure rod 6c, a pressure rod elastic pulling device, and a push-button flap reset mechanism. The push-button flap reset mechanism is used to drive the push-button flap 6a to reset. The horizontal shaft 6e is fixedly connected to the push-button flap 6a, and the horizontal shaft 6e is coaxial with the hinge rotation shaft of the push-button flap 6a. The rocker arm 6f is fixedly connected to the end of the horizontal shaft 6e, and the rocker arm 6f is perpendicular to the horizontal shaft 6e. The pressure rod 6c and the rocker arm 6f cooperate with each other and are driven by the seat ring 2 to generate action. The elastic pulling device of the pressure rod is fixedly connected to the pressure rod 6c. The combination of the horizontal shaft 6e, the rocker arm 6f, the pressure rod 6c, and the elastic pulling device of the pressure rod is provided in two sets, located on the left and right sides inside the toilet housing 1, respectively.

[0037] The pressure rod 6c is a vertically positioned long rod whose upper end contacts the lower surface of the toilet seat 2. The pressure rod 6c is fitted into a groove located on the side wall of the toilet seat 1. The lower end of the pressure rod 6c is arc-shaped; when the cross-section of the pressure rod 6c is circular, the lower end is semi-circular; when the cross-section of the pressure rod 6c is rectangular, the lower end is hemispherical. The pressure rod 6c is positioned above the rocker arm 6f, and its lower end presses against the rocker arm 6f. The upper end of the pressure rod 6c contacts the lower surface of the toilet seat 2, and the pressure rod 6c slides vertically under the swinging engagement of the toilet seat 2. The end of the rocker arm 6f has a groove that mates with the lower end of the pressure rod 6c. When the pressure rod 6c is pressed down, it drives the rocker arm 6f to swing, forming a tangential mechanism. The elastic pulling device of the pressure rod is a spring, one end of which is fixed to the pressure rod 6c, and the other end is fixed to the toilet seat housing 1.

[0038] The push-to-open mechanism has two forms. The first form consists of a pressing weight 6b fixedly connected to the push-to-open plate 6a. The pressing weight 6b is fixedly connected to the hinge end of the push-to-open plate 6a, and the push-to-open mechanism is located at the end opposite to the push-to-open plate 6a. The hinge axis between the push-to-open plate 6a and the push-to-open mechanism is the hinge shaft of the push-to-open plate 6a. The surface of the pressing weight 6b is perpendicular to the surface of the push-to-open plate 6a. Because the surfaces of the push-to-open plate 6a and the pressing weight 6b are perpendicular, when the push-to-open plate 6a is opened by the rocker arm 6f, it rotates more than 90° to prevent it from being splashed with feces. The second form of the push-to-open mechanism is a torsion spring sleeved at the hinge point between the push-to-open plate 6a and the toilet bowl 4.

[0039] It also includes an automatic flip-plate reset mechanism, which is an automatic flip-plate counterweight 7b fixedly connected to the hinge end of the automatic flip-plate 7a.

[0040] The height of the toilet bowl 4 does not exceed 15 cm, the distance between the lower opening of the toilet bowl 4 and the rear surface of the toilet seat 1 does not exceed 7.5 cm, the minimum distance between the lower opening of the toilet bowl 4 and the rear surface of the toilet seat 1 is less than the minimum distance between the inner opening of the seat ring 2 and the rear surface of the toilet seat 1, the area where the toilet seat 1 is located is completely within the projection range of the seat ring 2, and the range of fecal spillage is limited by the above dimensions.

[0041] The invention also includes a vent chamber 4a. Both the toilet bowl 4 and the vent chamber 4a are fixedly connected to the toilet housing 1. The vent chamber 4a is located below the toilet bowl 4, and its lower opening is a drain outlet 9. An automatic flap 7a is hinged to the lower opening of the vent chamber 4a. The automatic flap 7a and its counterweight 7b are fixedly connected, with the counterweight 7b fixedly connected at the hinge end of the automatic flap 7a. The two are connected by a hinge shaft 4a at the lower opening of the vent chamber. The lower opening of the vent chamber 4a is located directly below the lower opening of the toilet bowl 4, and the two openings are aligned. The upper opening of the vent chamber 4a is open. This non-closed structure provides sufficient space for pressing the flap 6a. The toilet bowl 4 is fixedly connected to the toilet housing 1 without gaps or openings at the connection point, directly sealing odorous gases inside the toilet housing 1.

[0042] The edges of the pressing flap 6a and the automatic flap 7a are provided with upward-folding flanges. The pressing flap 6a and the automatic flap 7a are disc-shaped with the edges folding upwards. When water flows out, the disc-shaped structure can retain some of the water.

[0043] This invention also includes a dual flushing system. The flushing system's outlets are located on the side walls of the toilet bowl 4 and the air-tight chamber 4a. A water outlet head 8 is fixedly connected to each outlet, ensuring the water flow direction is perpendicular to the outlet direction. The water outlet head 8 also controls the water flow range, causing water to flow or spray out in several fan-shaped areas, forming a ring spray from both sides of the water outlet head 8. Two water outlet heads 8 are symmetrically arranged on each of the left and right side walls of the toilet bowl 4. The water outlet heads 8 are positioned relatively high, with the maximum distance between the water outlet head 8 and the upper edge of the toilet bowl 4 not exceeding 5 cm. This maximum distance of no more than 5 cm between the water outlet head 8 and the upper edges of the toilet bowl 4 and the air-tight chamber 4a ensures that the water outlet head 8 is kept as far away as possible from the parabolic trajectory of fecal matter, preventing it from being splashed by fecal matter. A water outlet 8 is installed on the lower part of the wall in front of the air-tight chamber 4a. The water outlet 8 is located in the area below the automatic flap 7a. After the automatic flap 7a is flipped, the water outlet 8 is in the area in front of the automatic flap 7a, preventing fecal matter from flowing out of the lower opening of the toilet bowl 4 and contaminating the water outlet 8. The irregularly shaped flush nozzle and the concealed water channel design minimize the amount of water used for flushing while effectively preventing splashing, ensuring flushing effect and cleanliness; making fecal matter leave no residue or adhesion on the toilet bowl, resulting in a more hygienic toilet environment.

[0044] The front part of the upper surface of the seat ring 2 is higher than the rear part, and the front half of the seat ring 2 surface curves upwards at an angle. The rear end of the seat ring 2 has a vertically positioned baffle that curves upwards. The connection between the baffle and the upper surface of the seat ring 2 has a rounded transition surface, allowing the user to slide towards the middle and rear of the seat ring 2 after sitting down, directly providing positioning or fixation for the user. The front part of the upper surface of the seat ring 2 is higher than the rear part, allowing the user to naturally tilt and move backwards. The upward-curving baffle at the rear end of the seat ring 2, with its rounded transition surface, encourages the user to move towards or towards the rear of the seat ring 2. The user's buttocks feel comfortable contacting the rounded rear end of the seat ring 2, facilitating the alignment of waste with the lower outlet of the toilet bowl. This structure also elevates the user's legs, facilitating the defecation process and benefiting the user's health.

[0045] The invention also includes a seat inner pad 2a, which is fixedly connected to the upper surface of the toilet bowl housing 1. The seat ring 2 is a housing with an inner cavity that conforms to the shape of the seat inner pad 2a. A concealed annular water channel is provided along the upper edge of the toilet bowl 4. The annular water channel is located below the seat inner pad 2a, and during flushing, a concealed annular water flow is formed at the connection between the toilet bowl 4 and the seat ring 2.

[0046] Working principle or usage method:

[0047] The user opens the toilet seat lid 3 and sits on the seat ring 2. Under the influence of gravity, the seat ring 2 presses down the lever 6c. The arc-shaped end of the lever 6c presses down on the rocker arm 6f, causing the rocker arm 6f to swing. This, in turn, drives the horizontal shaft 6e to rotate, ultimately opening the lower opening of the toilet bowl 4 by rotating the hinge shaft of the pressing flap 6a, which is the horizontal shaft 6e. As the horizontal shaft 6e rotates, the pressing flap 6a rotates accordingly. The pressing flap 6a rotates more than 90°, and its surface is tilted relative to the vertical direction, completely avoiding fecal matter.

[0048] The toilet bowl 4 has a very low vertical height, so the waste hardly contacts the side walls of the toilet bowl 4 and flows out directly from the lower opening of the toilet bowl 4. Then, the waste comes into contact with the automatic flap 7a hinged to the lower opening of the air-tight chamber 4a, causing the automatic flap 7a to flip. The waste then enters the sewer pipe.

[0049] After use, the user stands up, and the lever 6c moves upward under the action of the elastic pulling device. The rocker arm 6f, which has lost its pressing function, rotates under the action of the pressing weight 6b, and the pressing flap 6a resets. At this time, the pressing flap 6a and the automatic flap 7a are both in a horizontal state. The pressing flap 6a, the automatic flap 7a and the toilet seat 3 form a three-layer isolation protection.

[0050] After flushing, the toilet bowl 4 and the vent chamber 4a are flushed by water from their respective channels, leaving virtually no residue on their side walls. The high-pressure flushing water in the toilet bowl 4 impacts the side walls, then contacts the push-button flap 6a fixedly connected to the lower opening of the toilet bowl 4, causing it to flip and allowing the flushing water to enter the vent chamber 4a. The high-pressure flushing water in the vent chamber 4a then impacts the side walls, and all the water in the vent chamber 4a contacts the automatic flap 7a fixedly connected to the lower opening of the vent chamber 4a. The automatic flap 7a flips, and the water flows into the sewer.
