Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of toilet structure, and particularly relates to a double-water-seal toilet with automatic water replenishment. BACKGROUND

[0002] Now there are various toilets on the market, which have various shapes and are colorful. According to their use, they can be divided into sitting type, squatting type and sitting-squatting dual-purpose type, and according to their functions, they can be divided into toilets with water tank and toilets without water tank, single-stage drain valve and double-stage drain valve, siphon type and direct flushing type.

[0003] The common points of the above-mentioned various toilets are: one is to use a water diversion elbow to separate the smell, and the other is to flush after defecation. Figure 1 and Figure 2 As shown in the drawings, the present application has two patents applied in 2006 and 2011, and the patent numbers are 200610034379.3 and 201110460199.2, and the invention names are "a water-saving toilet" and "an improved magnetic energy water-saving toilet".

[0004] The main feature of "a water-saving toilet" is that the sealing cover of the water-saving toilet replaces the water diversion elbow of the old toilet. Although the water-saving toilet achieves obvious water-saving effect, it also has the shortcomings of loud collision sound when the sealing cover is opened and closed, unstable water seal replenishment depth, and unadjustable sealing cover magnetic force. The "improved magnetic energy water-saving toilet" improves the "water-saving toilet" by adding a water seal replenishment device, a sealing cover opening and closing anti-collision buffer device and a sealing cover magnetic force adjusting equipment, which reduces the collision noise problem of the sealing cover opening and closing to a certain extent, increases the function of automatic water seal replenishment, but the water replenishment device has the problems of unstable operation, inconvenient magnetic force adjustment, and not obvious noise reduction, and the water seal device also has the problem of poor deodorization effect. SUMMARY

[0005] In order to overcome the shortcomings of the prior art, the purpose of the present application is to provide a double-water-seal toilet with automatic water replenishment and self-exhaustion, which can solve the problems of incomplete, unstable and not obvious noise reduction of the water replenishment device, and solve the problem of not smelling the odor of excrement during defecation.

[0006] The purpose of the present application is achieved by the following technical scheme:

[0007] A double-water-seal toilet with automatic water replenishment, comprising a toilet bowl and a water tank and an exhaust assembly arranged on the toilet bowl, the water tank is provided with a water inlet valve and a drain valve, characterized in that it further comprises:

[0008] A double-water-seal assembly arranged below the toilet bowl, comprising an upper water seal shell, an upper water seal shell cover, an upper water seal cover, a lower water seal shell and a lower water seal cover.

[0009] The upper water seal cover is arranged on the upper end of the upper water seal and is integrally sealed with the upper water seal, the bottom of the upper water seal is provided with an upper sewage outlet, the upper water seal cover is provided with an upper water seal groove corresponding to the toilet outlet, and the upper water seal cover is hinged to the upper water seal;

[0010] The upper water seal and the upper water seal cover are each provided with a first magnet group corresponding to each other;

[0011] The cover plate at the lower part of the upper water seal is integrally sealed with the upper end of the lower water seal;

[0012] The lower water seal cover is hinged to the lower water seal, the lower water seal is provided with a lower sewage outlet, the lower sewage outlet is connected with a municipal sewage pipeline, and the lower water seal cover is provided with a lower water seal groove corresponding to the upper sewage outlet of the upper water seal;

[0013] The lower water seal and the lower water seal cover are each provided with a second magnet group corresponding to each other;

[0014] The full-automatic water replenishing assembly arranged in the water tank comprises a water storage tank, a water inlet valve assembly, a low water level assembly and a water outlet valve assembly.

[0015] The water inlet valve assembly, the low water level assembly and the water outlet valve assembly are all installed in the water storage tank.

[0016] The present application has the following beneficial effects:

[0017] 1. The double water seal assembly installed in the present application, ① adopts an upper and lower double-layer structure and openable upper and lower water seal covers, and the double water seal mode mainly lies in that the lower water seal cover can effectively isolate the odor of the municipal sewage channel, so that the odor discharge of the municipal sewage channel can be reduced when the upper water seal cover is opened and closed, and therefore the double-layer odor isolation mode improves the odor isolation effect; ② in each water seal assembly, for example, in the upper water seal cover, when the upper water seal cover is turned down, the water in the second buffer groove is scraped by the upper scraper, and the noise generated in the turning-down process is reduced by the resistance and buffer force; when the upper water seal cover is reset upward, the water in the first buffer groove can only be squeezed out in a small amount from the gap between the first hydraulic plate and the first buffer groove, so that the resistance is generated to achieve the buffer effect, and the noise generated by the collision between the upper water seal cover and the toilet sewage outlet when the upper water seal cover is turned upward is reduced; ③ by limiting the deepest water level in the upper water seal groove, i.e. not more than 3 cm, preferably 2 cm, the problem that the excrement falling into the water during defecation is easy to splash the buttocks is solved.

[0018] 2. When the upper water seal cover is tilted downwards to empty the upper water seal trough, water needs to be replenished into the upper water seal trough in a timely manner to facilitate secondary use. The original invention, which used a float and magnetic suction to control the water level in the storage tank to drop to a low level and automatically open the inlet valve, suffers from instability issues such as high requirements for magnetic stability, premature opening of the inlet valve when the water level in the storage tank is still relatively high, and failure to automatically open the inlet valve when the storage tank is empty. Therefore, this invention further designs and improves upon this technology by triggering the inverted cup of the low water level control component to lose atmospheric pressure when the water level in the storage tank drops to approximately 1 cm from the bottom. This causes water to flow out, reducing the weight on one side of the inverted cup and thus preventing it from maintaining the control lever on the other side of the lifting lever. At this point, the control lever naturally droops, and the inlet valve opens simultaneously to begin water intake. This function significantly improves the utilization rate of water in the storage tank, noticeably reduces the usage frequency of all components in the fully automatic water replenishment component, thereby increasing the service life of the storage tank and completely resolving stability issues.

[0019] 3. The magnetic force adjustment component installed in this invention allows users to easily adjust the magnetic force of the water seal cap as needed via adjustment buttons on the outside of the toilet. For example, adjusting the magnetic force of the water seal cap to slightly exceed the state when the water seal cap is full allows for immediate opening and emptying of urine and feces after they enter the water seal cap, achieving a "purge and empty" function. It also allows for flushing with minimal water flow. If it is necessary to observe urine and feces to assess health, the magnetic force of the water seal cap can be adjusted to its strongest state, ensuring that the water seal cap can only be opened when flushing with sufficient water.

[0020] 4. The spray flushing component of this invention achieves flushing effect with a minimal amount of water, significantly saving flushing water. When used in temporary mobile toilets, it greatly reduces the space required for waste storage. Through industry reform, it can also allow for the targeted storage and direct transport of urban waste to suburban farmland for use as organic fertilizer, reducing urban pollution and wastewater treatment costs.

[0021] 5. The exhaust system of this invention precisely removes odors generated in the toilet pit through an exhaust fan, exhaust pipe, and flushing water channel, ensuring that the user will not smell the odor of their own excrement each time they use the toilet.

[0022] 6. The double water seal component of the present invention can also be made separately into a floor drain that does not clog and prevents pests such as snakes, rats, and cockroaches from entering the bathroom by modifying the overall external dimensions.

[0023] 7. The fully automatic water replenishment component of the present invention can also be manufactured as a separate product for use in places where precise water level control is required, such as poultry water troughs. It can solve the drinking water hygiene problem of poultry and other auxiliary production sites that require precise water level control. Attached Figure Description

DETAILED DESCRIPTION

[0040] The present application will be further described below in conjunction with the accompanying drawings and specific embodiments. The terms such as "upper", "inner", "middle", "left", "right" and "one" used in the specification are only for the convenience of clear description, and are not intended to limit the scope of the application. Changes or adjustments of the relative relationship without substantial changes in the technical content are also considered as the scope of the application. In the specification, the terms such as "front", "back", "upper", "lower" used in some parts are with the toilet bowl installed on the toilet with the water tank direction as "back", "upper", with the toilet base direction as "lower", and with the toilet bowl direction as "front".

[0041] The automatic water-supplying double-water-seal toilet of the present application can completely and stably automatically cycle the water seal water in the toilet according to the designed water seal depth; the opening and closing of the water seal cover is more silent; preferably, the odor generated during defecation and the situation of dirty water splashing on the buttocks during defecation are completely eliminated; the opening and closing force of the upper water seal cover 53 can be conveniently and randomly adjusted; the toilet is flushed by spraying, and the water consumption per flushing can be reduced to about 0.3 liters.

[0042] The structure and working principle of the automatic water-supplying double-water-seal toilet of the present application will be described in detail below:

[0043] An automatic water-supplying double-water-seal toilet, as shown in Figures 1 to 15 , comprises a toilet bowl 1, a water tank 2, a water inlet valve 3, a drain valve 4, a double-water-seal assembly 5, a full-automatic water-supplying assembly 6, an exhaust assembly 7, a magnetic force adjusting assembly 8, and a spraying toilet flushing kit.

[0044] A water tank 2 is located above and behind the toilet pit 1. An inlet valve 3 and a drain valve 4 are located inside the water tank 2. Flushing is initiated by pressing the drain valve 4. A flushing channel 75 is arranged around the inner circumference of the upper edge of the toilet pit 1. The flushing channel 75 is connected to and shares a vent pipe 73. The end of the vent pipe 73 is connected to the air intake side of an exhaust fan 71, allowing for precise removal of odors generated in the toilet pit 1 during use using the venting assembly 7. The venting assembly 7 of this invention consists of an exhaust fan 71, an exhaust pipe 73, and the connected flushing channel 75. A double water seal assembly 5 is located below the toilet pit 1. The double water seal assembly 5 is used to prevent odors from municipal pipes from entering the toilet, thus isolating odors. Simultaneously, it can automatically open and empty any additional waste or water, achieving immediate flushing and reducing odor. The fully automatic water replenishment component 6 is installed inside the water tank 2. It automatically circulates water to replenish the upper water seal trough 531, ensuring a set water depth in the trough when the water seal cover is closed, preventing odors from municipal pipes from entering the toilet. The adjustment button 81 of the magnetic adjustment component 8 is located around the toilet bowl, allowing for easy adjustment of the magnetic force of the upper water seal cover 53. Depending on user needs, a spray flushing component is installed under the toilet seat or lid for flushing after each use, achieving significant water savings.

[0045] Regarding the structure and working principle of the dual water seal assembly 5 of the present invention:

[0046] The dual water seal assembly 5 of the present invention adopts a dual water seal configuration, such as... Figures 1 to 9 As shown, the system includes an upper water seal cover 53, an upper water seal shell 52, an upper water seal shell cover 51, a lower water seal cover 57, a lower water seal shell 56, magnets A54, B55, C58, and D59. The upper water seal groove 531 of the upper water seal cover 53 corresponds to and matches the toilet drain outlet 11, used to collect excrement during toilet use, while simultaneously preventing odors from flowing into the toilet through a water seal. When the load inside the upper water seal cover 53 exceeds a set value, the upper water seal cover 53 automatically rotates and tilts open, emptying the contents into the lower water seal groove 571. The lower water seal cover 57 uses a water seal to prevent odors from the municipal sewer from flowing into the upper water seal shell 52. When the load inside the lower water seal cover 57 exceeds a set value, the lower water seal cover 57 automatically rotates and tilts open, emptying the contents into the municipal sewage pipe. Through a double water seal and secondary pouring method, the odor from the isolated toilet pit 1 is doubly protected from the municipal sewage pipes.

[0047] like Figures 3 to 9As shown, the upper water seal shell cover 51 includes a buffer water connection elbow 511, a buffer water introduction interface 512, a buffer water connection port 513, a water replenishment connection port 514, an extended water outlet 515, and a bayonet E 516. The upper water seal shell cover 51 seals the opening of the upper water seal shell 52, and the bayonet E 516 corresponds to the toilet sewage outlet 11. The upper water seal shell cover 51 has the water replenishment connection port 514 and the buffer water connection port 513 formed on the upper surface, and the extended water outlet 515 extending into the upper water seal groove 531 is formed on the lower surface of the upper water seal shell cover 51. The upper water seal cover 53 is provided with a groove 532 communicating with the upper water seal groove 531, and the tube opening of the extended water outlet 515 is about 2 cm away from the bottom surface of the groove 532 of the upper water seal cover 53. The water replenishment connection port 514 is connected to the water guide pipe 66 of the full-automatic water replenishment assembly 6, and the water replenishment connection port 514 and the extended water outlet 515 are used to replenish water in the upper water seal groove 531 to form a water seal to prevent odors below the upper water seal cover 53 from flowing to the bathroom. The buffer water introduction interface 512 is connected to the buffer water connection elbow 511, and is used to replenish buffer water in the first buffer groove 522 and the third buffer groove 562 of the double water seal assembly 5.

[0048] Regarding the upper water seal shell 52: The top end of the upper water seal shell 52 is provided with an opening, and the upper water seal shell 52 is provided with a first buffer groove 522 capable of storing water with a depth of 0.5 cm or more at the middle-upper part of the back surface. A first mounting box 525 with a lifting space of 1 cm or more for the magnet fixing box 85 is arranged below the first buffer groove 522. The bottom front surface of the upper water seal shell 52 is provided with an upper sewage outlet 524 leading to the lower water seal shell 56, and a second buffer groove 523 is arranged between the first buffer groove 522 and the upper sewage outlet 524. The inner walls of the upper water seal shell 52 are each provided with a first U-shaped clamping groove 521 clamping the two hinge shafts A 536 of the upper water seal cover 53. The outer side surface of the upper water seal shell 52 is provided with a water guide elbow 527 introducing water overflowing from the first buffer groove 522 into the third buffer groove 562. The upper sewage outlet 524 of the middle-lower part of the upper water seal shell 52 is provided with a lower water seal shell cover 526 for sealing the opening of the lower water seal shell 56 at a position about 3.5 cm above. The upper water seal shell cover 51 seals the opening of the upper water seal shell 52, and the water inlet 5271 of the water guide elbow 527 is arranged at a position about 0.5-1 cm away from the bottom surface of the first buffer groove 522. The water outlet 5272 of the water guide elbow 527 is arranged on the panel of the lower water seal shell cover 526, and the water storage depth of the buffer water guide elbow 527 is set to 3±1 cm.

[0049] About the lower water seal 56: the top end of the lower water seal 56 is open, the upper middle part of the front of the lower water seal 56 is provided with a third buffer groove 562 capable of storing water depth of 0.5 cm or more, the second mounting box 565 provided with magnet C58 is arranged below the third buffer groove 562, the lower sewage outlet 564 is arranged at the bottom of the back of the lower water seal 56, which is communicated with the municipal sewage pipe, the fourth buffer groove 563 is arranged between the third buffer groove 562 and the lower sewage outlet 564, the second U-shaped clamping groove 561 is arranged on both sides of the inner wall of the lower water seal 56, which is clamped into the two sides of the hinge shaft B574 of the lower water seal cover 57, and the lower water seal cover 526 seals the shell opening of the lower water seal 56.

[0050] About the upper water seal cover 53: the two sides of the middle and rear part of the upper water seal cover 53 are provided with hinge shaft A536 fitted into the first U-shaped clamping groove 521 on both sides of the inner wall of the upper water seal 52, the front of the hinge shaft A536 is provided with an upper water seal groove 531 capable of storing water depth of about 2 cm, the first mounting clamping hole 533 provided with magnet B55 is arranged at the middle part of the rear of the hinge shaft A536, the groove 532 and the counterweight groove 534 communicated with the upper water seal groove 531 are arranged on both sides of the first mounting clamping hole 533, the upper draw plate 537 is arranged below the upper water seal groove 531, which is drawn into the second buffer groove 523, and the bottom surface of the groove 532, the bottom surface of the magnet B55 and the bottom surface of the counterweight groove 534 at the bottom of the rear of the hinge shaft A536 are combined to form the upper hydraulic plate 535 with an area slightly smaller than that of the bottom of the first buffer groove 522.

[0051] About the lower water seal cover 57: the two sides of the middle and rear part of the lower water seal cover 57 are provided with hinge shaft B574 fitted into the second U-shaped clamping groove 561 on both sides of the inner wall of the lower water seal 56, the lower water seal groove 571 capable of storing water depth of about 3 cm is arranged behind the hinge shaft B574, the second mounting clamping hole 572 provided with magnet D59 is arranged at the middle part of the front of the hinge shaft B574, the lower draw plate 575 is arranged below the lower water seal groove 571, which is drawn into the fourth buffer groove 563, and the bottom surface of the magnet D59 and the surface plate on both sides of the front of the hinge shaft B574 are combined to form the lower hydraulic plate 573 with an area slightly smaller than that of the bottom of the third buffer groove 562.

[0052] In the design of the upper water seal groove 531 of the upper water seal cover 53, the deepest water storage depth of the upper water seal groove 531 is limited to not more than 3 cm, preferably 2 cm, according to actual experience, which can realize that when the human excretion falls into the upper water seal groove 531, it will not splash dirty water on the buttocks, and solve the problem that the dirty water occasionally splashes on the buttocks during defecation, which is not only unhygienic but also easy to cause long-term psychological shadow of dirty water splashing on the buttocks.

[0053] In the process of opening and closing of the upper water seal cover 53 and the lower water seal cover 57, the closer the distance between the magnets, the faster the speed, and vice versa. In the environment where the upper water seal cover 53 and the lower water seal cover 57 almost completely rely on magnetic force to open and close, the noise generated by the collision with the bottom plate or the sewage outlet is certain. In order to better reduce the noise in the opening and closing process, the following design is made:

[0054] The upper water seal shell 52 is provided with a first buffer groove 522 for containing water, which is located directly above the first mounting box 525. The area of the first buffer groove 522 is slightly larger than the area of the upper hydraulic plate 535 of the upper water seal cover 53. When the upper water seal cover 53 is turned down to dump the contents in the groove and then turned up to close, the upper hydraulic plate 535 is pressed into the water in the first buffer groove 522 as a whole. At this time, the water in the first buffer groove 522 can only be squeezed out upward from the gap between the four sides of the first buffer groove 522 and the periphery of the upper hydraulic plate 535, thereby reducing the noise generated by the collision with the sewage outlet 11 of the toilet bowl when the upper water seal cover 53 is quickly turned up to close. The upper water seal shell 52 is provided with a second buffer groove 523 for containing water between the first mounting box 525 and the upper sewage outlet 524. The second buffer groove 523 is located below the first buffer groove 522 in a stepped manner. When the upper water seal cover 53 is turned down to open, the upper guide plate 537 located below the upper water seal groove 531 is guided into the water in the second buffer groove 523 to generate a buffer force, thereby effectively reducing the noise generated by the collision with the bottom plate of the upper water seal shell 52 when the upper water seal cover 53 is quickly turned down.

[0055] The lower water seal shell 56 is provided with a third buffer groove 562 for containing water, which is located directly above the second mounting box 565. The area of the third buffer groove 562 is slightly larger than the area of the lower hydraulic plate 573 of the lower water seal cover 57. When the lower water seal cover 57 is turned down to dump the contents in the groove and then automatically turned up to close, the lower hydraulic plate 573 is pressed into the water in the third buffer groove 562. At this time, the water in the third buffer groove 562 can only be squeezed out upward from the gap between the four sides of the third buffer groove 562 and the periphery of the lower hydraulic plate 573, thereby reducing the noise generated by the collision with the upper sewage outlet 524 when the lower water seal cover 57 is quickly turned up to close. The lower water seal shell 56 is provided with a fourth buffer groove 563 for containing water between the second mounting box 565 and the lower sewage outlet 564. The fourth buffer groove 563 is located below the third buffer groove 562 in a stepped manner. When the lower water seal cover 57 is turned down to open, the lower guide plate 575 located below the lower water seal groove 571 is guided into the water in the fourth buffer groove 563 to generate a buffer force, thereby effectively reducing the noise generated by the collision with the bottom plate of the lower water seal shell 56 when the lower water seal cover 57 is quickly turned down.

[0056] The upper water seal cover 53 can be provided with a magnetic force to bear a weight slightly greater than the weight of the upper water seal tank 531 filled with water seal, and the upper water seal tank 531 is provided with a loading capacity greater than the space filled with water seal, that is, after the upper water seal tank 531 is filled with water seal water, a certain loading space is reserved. When the feces discharged from the toilet continues to increase the weight of the upper water seal tank 531, causing the magnetic force provided by the upper water seal cover 53 to be unable to bear the weight loaded by the upper water seal tank 531, the upper water seal cover 53 will automatically turn down and open to dump the feces and water in the upper water seal tank 531. In this case, the upper water seal cover 53 is not flushed open, and the upper water seal tank 531 has no subsequent water to supplement the water seal, that is, there is no water seal, and the odor below the upper water seal cover 53 cannot be isolated. At this time, the full-automatic water supplement assembly 6 needs to supplement water to the groove 532 through the water supplement connection port 514 of the upper water seal shell cover 51. The following structure is adopted: a groove 532 is provided on one side of the first mounting clamp 533, the groove 532 is communicated with the upper water seal tank 531, and a water outlet 515 extending out is mounted about 2 cm above the groove 532. When the water in the groove 532 fails to cover the water outlet 515, the water in the full-automatic water supplement assembly 6 will always supplement water to the groove 532. When the water in the groove 532 rises to cover the water outlet 515, the full-automatic water supplement assembly 6 automatically stops supplementing water to the groove 532.

[0057] In the process of opening and closing the upper water seal cover 53 and the lower water seal cover 57, the water in the first buffer tank 522, the second buffer tank 523, the third buffer tank 562, and the fourth buffer tank 563 will inevitably overflow and lose. Therefore, it is necessary to supplement water to the buffer tank in time, and the following structure is adopted: a buffer water introduction port 512 is arranged below the toilet flushing channel 75, the buffer water introduction port 512 is connected to the buffer water connection port 513 of the upper water seal shell cover 51 through the buffer water connection elbow pipe 511, and the buffer water connection port 513 is aligned below the counterweight tank 534 and the first buffer tank 522, that is, the water flowing down from the buffer water connection port 513 flows into the first buffer tank 522 and the counterweight tank 534 at the same time. The overflow water of the counterweight tank 534 flows into the first buffer tank 522, the overflow water of the first buffer tank 522 flows into the third buffer tank 562 and the lower water seal tank 571 below the water inlet port 5271 of the water guide elbow pipe 527, the overflow water of the third buffer tank 562 flows into the fourth buffer tank 563, and the overflow water of the fourth buffer tank 563 is discharged into the municipal sewage pipeline through the lower sewage outlet 564. The buffer water of the second buffer tank 523 is supplemented by the overflow water of the upper water seal tank 531 and the water splashed into the first buffer tank 522 when the upper water seal cover 53 is closed each time.

[0058] It should be noted that the water storage depth of the connecting bend 511 and the water guide bend 527 is 3±1 cm, and the water guide bend 527 is provided with a screen at one end to prevent various pests from flowing into the toilet and the bathroom. The first mounting socket 533 is provided with a counterweight groove 534 on one side, which is mainly used to increase the weight of the upper hydraulic plate 535 on one side of the upper water seal cover 53 to drive the upper water seal cover 53 to reset.

[0059] The upper water seal shell 52, the upper water seal cover 53, the lower water seal shell 56, and the lower water seal cover 57 are processed by welding or one-piece forming process of sheet metal parts, and can be processed by one-piece forming or 3D printing process of plastic parts or metal parts. After processing and forming, the corresponding required groove structure is formed.

[0060] The working principle of the double water seal assembly 5 is as follows:

[0061] (1) When the double water seal assembly 5 is installed under the toilet bowl 1 and can be normally used, the upper water seal cover 53 is inverted and clamped to the toilet bowl drain 11 under the action of the attraction of the magnet A 54 and the magnet B 55, and the lower water seal cover 57 is inverted and clamped to the upper drain 524 under the action of the attraction of the magnet C 58 and the magnet D 59.

[0062] (2) When normally defecating or flushing the toilet, the water or human excrement in the upper water seal groove 531 gradually increases, the upper water seal cover 53 loses the balance between the weight of the upper water seal groove 531 and the attraction of the magnet A 54 and the magnet B 55 and the weight of the magnet B 55 and the counterweight groove 534, and cannot bear the weight of the full excrement and water in the upper water seal groove 531. The upper water seal cover 53 automatically flips down and tilts open, and the water and excrement in the upper water seal groove 531 pour into the lower water seal groove 571. At the same time, the upper water seal cover 53 below the upper water seal cover 53 is drawn into the second buffer groove 523 to generate resistance, slowing down the opening of the upper water seal cover 53, thereby eliminating the noise generated by the collision of the upper water seal cover 53 and the bottom plate of the upper water seal shell 52.

[0063] (3) When the objects in the upper water seal groove 531 are poured out, the upper water seal cover 53 is pressed down under the action of the attraction of the magnet B 55 and the magnet A 54 and the weight of the magnet B 55 and the counterweight groove 534, and the upper water seal cover 53 is flipped up again. When the upper water seal cover 53 flips up close to the toilet bowl drain 11, the upper hydraulic plate 535 presses the water in the first buffer groove 522 downward to generate hydraulic resistance, and the upper water seal cover 53 slowly inverts and tightly closes the toilet bowl drain 11, thereby eliminating the noise generated by the collision of the upper water seal cover 53 when closing the toilet bowl drain 11. At the same time that the upper water seal cover 53 inverts and tightly closes the toilet bowl drain 11, the automatic water replenishing assembly 6 starts to replenish water to the groove 532, and when the water in the groove 532 rises to just cover the water outlet 515, the automatic water replenishing assembly 6 automatically stops replenishing water to the groove 532 under the vacuum environment of the atmospheric pressure.

[0064] (4) When the toilet is normally flushed, the upper water cover 53 repeats the above-mentioned operation mode, and at this time, the suction force of the magnet D59 of the lower water cover 57 and the magnet C58 cannot resist the heavy pressure of a large amount of flushing water, and the lower water cover 57 is flipped and tilted downward to open, and when the lower water cover 57 is flipped downward to the lower guide plate 575 to enter the fourth buffer groove 563 to generate resistance, the speed of the opening of the lower water cover 57 is slowed down, and the noise generated by the collision of the lower water cover 57 with the bottom plate of the lower water cover shell 56 is eliminated.

[0065] (5) When the object in the lower water cover 57 is dropped, the lower water cover 57 is flipped upward again under the suction force of the magnet D59 and the magnet C58, and when the lower water cover 57 is flipped upward to approach the upper sewage outlet 524, the lower hydraulic plate 573 presses the water in the third buffer groove 562 downward to generate hydraulic resistance, the speed of the closing of the lower water cover 57 is slowed down, and the noise generated by the collision of the lower water cover 57 with the upper sewage outlet 524 is eliminated.

[0066] (6) When the flushing water flows through the buffer water introduction interface 512 of the flushing water channel 75 each time the toilet is flushed, a small amount of water flows into the first buffer groove 522 and the counterweight groove 534 through the buffer water introduction interface 512, the buffer water connection elbow 511 and the buffer water connection port 513. When the water in the first buffer groove 522 rises above the buffer water introduction elbow water inlet 5271, the water overflowing from the first buffer groove 522 flows into the third buffer groove 562 and the lower water cover groove 571 through the water introduction elbow 527 to supplement the buffer of the third buffer groove 562 and the water seal of the lower water cover groove 571; at the same time, the subsequent water poured into the lower water cover groove 571 by the upper water cover 53 flipped and opened downward during flushing is supplemented, so as to achieve the effect of supplementing water into the lower water cover 57 in two directions at the same time, and the water in the second buffer groove 523 and the fourth buffer groove 563 is supplemented by the water overflowing from the first buffer groove 522 and the third buffer groove 562 when the upper water cover 53 and the lower water cover 57 are closed each time, by the upper hydraulic plate 535 and the lower hydraulic plate 573.

[0067] As shown in Figure 1 , Figure 2 , Figures 10 to 13 , the structure and working principle of the full-automatic water supplement assembly 6: the full-automatic water supplement assembly 6 of the present application is used for automatically supplementing the water seal of the upper water cover groove 531, and the full-automatic water supplement assembly 6 comprises a water storage tank 61 with a tank cover, a water storage tank cover 62, a water inlet valve assembly 63, a water outlet valve assembly 64 and a low water level assembly 65.

[0068] The water storage tank 61 can be set as a square column or a cylinder according to the environment of the installation site. The water storage tank 61 of the present application is most suitable for installation in the toilet water tank 2. Due to the space limitation of the existing square water tank 2 of the toilet in the market, in order to maximize the use of the space of the water storage tank 61, the water storage tank 61 is set as a square column shape, the tank opening of the water storage tank 61 is set as an open type, the tank wall of the water storage tank 61 is provided with a mounting hole C611, and the tank bottom of the water storage tank 61 is provided with a water outlet 612. The water outlet 612 is arranged through the mounting hole arranged at the bottom of the toilet water tank 2 to install and fix the full-automatic water replenishing assembly 6 in the toilet water tank 2.

[0069] The faceplate of the water storage tank cover 62 is provided with a track groove 621 corresponding to the position of the air inlet of the upper end of the exhaust pull pipe 641, which facilitates the lifting and stretching of the exhaust pull pipe 641. The water storage tank cover 62 is used to tightly seal the tank opening of the water storage tank 61.

[0070] The water inlet valve assembly 63 is used to control the water inlet of the water storage tank 61. The water inlet valve assembly 63 includes a water inlet valve body 631, a pressure valve cover 632, a latch 633, a control lever 634, a valve plug 636, and a water float 635. The water inlet valve assembly 63 is installed and fixed at the mounting hole C611 position on the side of the water storage tank 61.

[0071] The water inlet valve body 631 includes a water inlet connection port 6311 and a pressure valve cover bayonet 6312. The water inlet connection port 6311 extends from the mounting hole C611 to connect the water pipe, and the pressure valve cover bayonet 6312 installs and fixes the pressure valve cover 632.

[0072] The pressure valve cover 632 is provided with a latch hole A6321 and a pressure valve hole 6322. The latch hole A6321 is tied to the control lever 634 through the latch 633, and the pressure valve hole 6322 is pressed or released by the valve plug 636 installed and fixed on the control lever 634 to control the water inlet valve to stop water or water inlet.

[0073] The water floating member 635 comprises a float 6351, a clamping shaft B63511, a U-shaped clamping hole 63512, a drain hole 63513, a clamping plate 63514, a float 6352, a hanging ring A63521, and a float plug 6353. The float 6351 is fixedly installed on the inner circumferential surface of the water storage tank 61 in a manner of being pasted, welded, or screwed. The top of the float 6351 is upward, and the side of the top of the float 6351 is provided with the clamping shaft B63511 for assembling the jacking lever 653. The bottom of the float 6351 is further provided with the drain hole 63513 for hanging the float plug 6353. The side of the float 6351 facing the mounting hole C611 is provided with the U-shaped clamping hole 63512, which extends upward to the top of the float 6351. The depth of the U-shaped clamping hole 63512 is set according to the space required for the lifting of the lever 634. The side of the float 6351 facing the water storage tank 61 is provided with the clamping plate 63514, which is clamped into the clamping groove C6423. The upper end of the float 6351 is provided with the clamping shaft B63511, which is clamped into the clamping hole C6522 of the jacking lever 653. The lower end of the float plug 6353 is cup-shaped, and the upper end is designed with a hook. The float plug 6353 is hung below the drain hole 63513. The diameter of the float plug 6353 is greater than that of the drain hole 63513. When the float plug 6353 floats and blocks the drain hole 63513, the water in the water storage tank 61 rises above the drain hole 63513, and the water in the water storage tank 61 will not flow into the float 6351. When the water in the water storage tank 61 decreases, the water in the float 6351 will flow out through the drain hole 63513. The float 6352 is invertedly clamped in the float 6351. The float 6352 is hung on the control lever 634 through the hanging ring A63521 at the top. The float 6352 uses the buoyancy or its own weight to lift or lower the control lever 634 to control the water inflow or stop the water inflow.

[0074] The control lever 634 is provided with a valve plug groove 6341, a pin hole B 6342 and a bayonet B 6343. The valve plug groove 6341 is located at the top end of the control lever 634 and is used to install the valve plug 636. The pin hole B 6342 is located near the valve plug groove 6341 and is installed in the pin hole A 6321 of the pressure valve cover 632 through the pin 633. The bayonet B 6343 is located in the middle of the control lever 634 and is clamped into the bayonet groove B 6411 of the exhaust pull pipe 641. The other section of the control lever 634 passes through the U-shaped bayonet B 63512 of the float 6351 and the hanging ring A 63521 at the top end of the float 6352. When the float 6352 falls to the bottom of the float 6351, the float 6352 is hung on the control lever 634 through the hanging ring A 63521. The control lever 634 is hung due to the weight of the float 6352 and the exhaust pull pipe 641, and the valve plug 636 installed at the other end is lifted and separated from the pressure valve hole 6322 to start water inlet. When the float 6352 rises and lifts the control lever 634, the control lever 634 is pivoted at the pin hole B 6342, the pin 633 and the pin hole A 6321, and the valve plug 636 installed at the other end is pressed to stop water inlet.

[0075] The water outlet valve assembly 64 includes an exhaust pull pipe 641, an air inlet, a bayonet groove B 6411, a water outlet valve film 642, an exhaust connection pipe 6421, an air outlet 6422 and a bayonet groove C 6423. The upper section of the exhaust pull pipe 641 is provided with the bayonet groove B 6411, which is matched with the bayonet in the middle of the control lever 634. The lower end of the exhaust pull pipe 641 is integrally sealed and matched with the pipe interface of the water outlet valve film 642. The water outlet valve film 642 is designed with the exhaust connection pipe 6421 connected with one end of the exhaust pull pipe 641. The air outlet 6422 is located in the middle of the water outlet valve film 642 and faces the water outlet 612. The opposite end of the exhaust connection pipe 6421 of the water outlet valve film 642 is provided with the bayonet groove C 6423, and the bottom surface of the water outlet valve film 642 can cover and block the water outlet 612.

[0076] The exhaust connecting pipe 6421 has an air inlet and an air outlet 6422, the air inlet is arranged at one end of the water outlet valve diaphragm 642, and the air inlet is connected with the exhaust pull pipe 641. The air outlet 6422 is arranged at the middle of the water outlet valve diaphragm 642 and faces downward to the position of the water outlet 612. The clamping groove C6423 is arranged at the opposite end of the air inlet, and the clamping groove C6423 is clamped into the clamping plate 63514 of the float 6351 to fix the water outlet valve diaphragm 642 near the water outlet 612, the bottom surface of the water storage tank 61. The bottom surface of the water outlet valve diaphragm 642 can cover the blocked water outlet 612, when the control lever 634 is lowered, the exhaust pull pipe 641 clamped on the control lever 634 is lowered together, and the water outlet valve diaphragm 642 connected with the exhaust pull pipe 641 is lowered at the same time to cover the water outlet 612 to stop water outlet. When the float 6352 is floated to lift the control lever 634, the exhaust pull pipe 641 clamped on the control lever 634 is pulled up together, and the water outlet valve diaphragm 642 connected with the exhaust pull pipe 641 is pulled up at the same time to separate from the water outlet 612, and the water outlet 612 starts to automatically supplement water to the upper water sealing groove 531.

[0077] The low water level assembly 65 includes a lifting lever 653, a clamping hole C6522, a clamping hook 6532, a conversion support B652, a hanging ring B6521, a reverse buckle cup 651, a clamping shaft C6511, a water outlet gap 6512, and a direction control strip 6513. The middle part of the lifting lever 653 is rotatably connected with the clamping shaft B63511 of the float 6351 through the male and female buckles 6531, one end of the lifting lever 653 is located below the control lever 634 to press, the other end of the lifting lever 653 is provided with a clamping hook 6532, the hanging ring B6521 arranged on the top surface of the conversion support B652 is clamped into the clamping hook 6532 to form a movable link, the clamping hole C6522 arranged on the lower side of the hanging ring B6521 is clamped into the clamping shaft C6511 arranged on the two sides of the reverse buckle cup 651 to form a rotatable connection, the clamping shaft C6511 is arranged on the two sides of the reverse buckle cup 651 and slightly deviates from the bottom of the cup, in the state that the installed reverse buckle cup 651 is naturally placed with the cup opening downward, the direction control strip 6513 arranged on the cup opening of the reverse buckle cup 651 controls the direction of the reverse buckle cup 651 to be not completely vertical, and the cup opening of the reverse buckle cup 651 is provided with the water outlet gap 6512.

[0078] The working principle of the full-automatic water supplement assembly 6 is as follows:

[0079] Before the water inlet valve assembly 63, the water outlet valve assembly 64, the low water level assembly 65 and the water inlet pipe 66 of the full-automatic water replenishing assembly 6 are all installed and the water inlet connecting port 6311 is connected with the tap water pipe, the control lever 634 and the float 6352 hung on the control lever 634, the exhaust pull pipe 641 and the water outlet valve rubber sheet 642 are all naturally drooped, the end of the control lever 634, on which the valve plug 636 is installed and fixed, is upwardly tilted, the valve plug 636 is separated from the pressure valve hole 6322, and the water inlet valve assembly 63 is in the water inlet state. At this time, the control lever 634 presses the jacking lever 653 of the low water level assembly 65 downward, meanwhile, the other end lifts the conversion support B 652 and the inverted cup 651 to be naturally drooped, and the water outlet valve rubber sheet 642, which is drooped together with the exhaust pull pipe 641, blocks the water outlet port 612.

[0080] When the water inlet valve assembly 63 is connected to the water pipe to start water inflow, the water tank 61 will discharge the excess air through the exhaust pull tube 641 due to the space occupied by the inflow water. When the water in the water tank 61 gradually increases and starts to flood the cup opening water gap 6512 of the inverted cup 651, the inverted cup 651 will lose balance and naturally droop downward due to the position of the rotation support point of the inverted cup 651 being set at the middle of the cup bottom side, and the cup opening side being longer. Therefore, a vacuum is generated in the inverted cup 651 to form buoyancy, and the inverted cup 651 starts to float in the designed direction that can ensure the natural upward floating of the inverted cup 651 under the action of the direction control strip 6513. When the water level in the water tank 61 rises to exceed the float 6353 at the bottom of the float tube 6351, the float 6353 is lifted to press the drain opening 63513, blocking the rising water from entering the float tube 6351. When the water in the water tank 61 rises to flood the inverted cup 651 floating on the water surface, the inverted cup 651 has been deflected by 90 degrees or more due to the buoyancy, and the inverted cup 651 is filled with water. At this time, the inverted cup 651 filled with water loses buoyancy and naturally sinks to a relatively vertical posture. When the water in the water tank 61 rises to about 2 cm from the tank cover 62 and starts to exceed the barrel opening position of the float tube 6351, the excess water flows into the float tube 6351, and the float 6352 in the float tube 6351 rises due to the increase of water flowing into the float tube 6351. The float 6352 rises to lift one end of the control lever 634, and the other end connected to the valve plug 636 flips downward and blocks the pressure valve hole 6322, stopping the water inlet valve assembly 63 from inflowing water. At this time, the water tank 61 forms a vacuum state of atmospheric pressure, and the exhaust pull tube 641 connected to the control lever 634 pulls the water outlet valve film 642 upward to open the water outlet 612, and the water tank 61 starts to automatically supplement the water seal in the upper water seal groove 531. The air inlet of the exhaust pull tube 641 is inserted into the track groove 621 of the water tank cover 62. At the same time, the lifting lever 653 under the control lever 634 rises, and the inverted cup 651 connected to the other side of the lifting lever 653 through the conversion support B652 also descends. At this time, the cup opening of the inverted cup 651 has contacted the bottom surface of the water tank 61. When the water in the upper water seal groove 531 is supplemented to the set depth (the specific depth varies according to different toilets, and the depth is below 3 cm, preferably 2 cm), and the water surface floods the extended water outlet 515, the water in the water tank 61 stops supplementing due to the formation of atmospheric pressure. Conversely, when the water in the upper water seal cover 53 is drained, and the extended water outlet 515 is not flooded by water, the water in the water tank 61 loses the effect of atmospheric pressure, and the water in the water tank 61 reflows into the upper water seal cover 53 to automatically implement water supplement.When the water in the water storage tank 61 is circulated back and forth to replenish the water seal tank 531, and the water level in the water storage tank 61 is about to drop to the point where the buoyancy of the float 6352 is not enough to hold the control lever 634 closed to block the pressure valve hole 6322, the inverted cup 651 of the low water level assembly 65 has begun to emerge from the water surface. At this time, the mouth of the inverted cup 651 filled with water is still submerged in the water, creating a vacuum atmospheric pressure state. Although the cup body is partially exposed to the air, the water in the cup body continues to be full. At this time, the exposed part of the cup body produces weight, causing the inverted cup 651 to sink and press downward. When the inverted cup 651 sinks and presses downward, the lifting lever 653, on one side of the inverted cup 651 sinks and presses downward, and on the other side of the lifting lever 653 lifts the control lever 634, thereby holding the control lever 634 and blocking the pressure valve hole 6322.

[0081] When the water in the water storage tank 61 drops to the point where it cannot submerge the mouth of the inverted cup 651, the inverted cup 651 loses the condition of vacuum atmospheric pressure, and the water in the inverted cup 651 begins to flow out. When the weight of the water in the cup is less than the total weight of the control lever 634, the float 6352, the water outlet valve film 642, and the exhaust pull tube 641, the control lever 634, the float 6352, the water outlet valve film 642, and the exhaust pull tube 641 instantaneously drop. At the same time, one side of the control lever 634, which supports the valve plug 636, flips upward and opens the pressure valve hole 6322, and the water inlet valve assembly 63 begins to fill with water. At the same time, the water outlet valve film 642 covers the water outlet 612 to stop replenishing water. That is, the full-automatic water replenishing assembly 6 returns to the water filling state. From now on, it automatically maintains the above-mentioned cycle water replenishing operation mode for a long time.

[0082] As shown in Figure 1 , Figure 2 , Figure 14 The structure and working principle of the exhaust assembly 7 are as follows:

[0083] The exhaust assembly 7 of the present application is used to accurately exhaust the odor generated in the toilet bowl 1 during defecation. The exhaust assembly 7 comprises an exhaust fan 71, an exhaust hole 72, an exhaust connecting pipe 73, an exhaust duct 74, and a flushing water channel 75. The exhaust fan 71 is arranged and fixed near the toilet tank 2 and corresponds to the position of the exhaust hole 72.

The exhaust duct 74 is arranged below and at the two sides of the water tank 2. One end of the exhaust duct 74 arranged below the water tank 2 is connected to the flushing water channel 75, and the other end of the exhaust duct 74 arranged at the two sides of the water tank 2 is connected to the exhaust connecting pipe 73 connected to the exhaust fan 71. The flushing water channel 75 is a water channel formed below the water tank 2 and around the inner periphery of the toilet bowl 1. When flushing, the flushing water channel 75 is preferentially used for water passage. When the exhaust fan 71 is turned on to exhaust the odor from the toilet bowl, the exhaust assembly 7 uses the flushing water channel 75 for ventilation and exhaust. The exhaust hole 72 is arranged near the water tank 2 to facilitate the installation of the small exhaust fan 71 and the connection of the exhaust connecting pipe 73.

[0084] Regarding the working principle of the exhaust assembly 7, the exhaust assembly 7 is operated as follows:

[0085] When the exhaust assembly 7 is installed in communication, the power of the exhaust fan 71 is turned on to start exhaust, and the exhaust fan 71 precisely sucks all the odor generated in the toilet bowl 1 through the exhaust connecting pipe 73, the exhaust pipe 74 and the flushing water channel 75, and then discharges it out of the toilet through the exhaust hole 72.

[0088] The adjusting button 81 is installed and arranged above the flushing water channel 75 between the water tank and the toilet cover plate, and the appearance of the adjusting button 81 is mainly set to be convenient for rotation, which can be round or flat. The lower end of the adjusting button 81 is fixedly connected with the adjusting rod 83, and the locking of the adjusting button 81 after rotation adjustment is performed by the locking box 82 arranged together with the adjusting button 81. The function and appearance of the locking box 82 are determined according to the arrangement of the adjusting button 81, and the locked adjusting button 81 can only be unlocked by manual operation. A mounting hole A 87 slightly wider than the diameter of the adjusting rod 83 is arranged through the flushing water channel 75 or the toilet panel below the adjusting button 81. A card B 86 is arranged to be clamped into the clamping groove A 831 at the middle part of the adjusting rod 83 below the flushing water channel or the toilet panel. A thread 832 with a length of more than 3 cm is arranged at the lower end of the adjusting rod 83, and the thread 832 is screwed into the nut 841 arranged in the conversion support A 84. The nut 841 is arranged and fixed at the middle part of the conversion support A 84. The clamping shaft A 842 is arranged at both ends of the round rod of the conversion support A 84, and the clamping shaft A 842 is rotatably connected by penetrating the clamping port A 852 arranged on both sides of the magnet fixing box 85. The magnet fixing box 85 is provided with a magnet mounting groove 851 with the same size as the magnet A 54, and the magnet A 54 is arranged and fixed in the magnet mounting groove 851 of the magnet fixing box 85. The magnet fixing box 85 with the arranged magnet A 54 is arranged in the first mounting box.

[0089] Regarding the working principle of the magnetic force adjusting assembly 8, the magnetic force adjusting assembly 8 is operated as follows:

[0090] When the adjusting magnetic component 8 is installed and in normal working order, it is installed on the toilet flushing pipe. The adjusting button 81 near the toilet seat mounting hole rotates left and right, causing the adjusting rod 83 connected and fixed below the adjusting button 81 to rotate as well. The diameter of the adjusting button 81 and the clip B86 connected and fixed to the adjusting rod 83 is larger than the diameter of the mounting hole A87, so that the adjusting rod 83 cannot move up or down after being inserted into the mounting hole A87. After the adjusting rod 83 is screwed into the adjusting conversion bracket A84 nut 841, the adjusting conversion bracket A84 rises or falls with the rotating adjusting rod 83. At the same time, the magnet fixing box 85 connected to the conversion bracket A84 and the magnet A54 installed and fixed in the magnet fixing box 85 also rise or fall. The rise or fall of the magnet A54 causes the distance between the magnet A54 and the magnet B55 to increase or decrease. The distance between the magnet A54 and the magnet B55 directly affects the mutual attraction, that is, it affects the weight or impact force required to open the water seal cover 53. Once the attraction between magnet A54 and magnet B55 is adjusted to the ideal state, the adjustment button 81 is locked by the locking box 82. The adjustment button 81 cannot be rotated before it is unlocked.
