Description

Technical Field

[0001] The invention relates to the technical field of toilets, and in particular to a flip-type dry-wet separation structure and a biodegradable toilet. Background Art

[0002] Biodegradable toilets are a new type of toilet that has appeared in recent years. They can degrade human feces through microorganisms. They are particularly suitable for use in indoor environments such as RVs, yachts, and nursing homes for the care of elderly people with limited mobility where it is inconvenient to collect water or discharge waste.

[0003] Please refer to Chinese patents with publication numbers CN220735262U and CN219374488U. Existing biodegradable toilets usually discharge urine and feces directly into a biodegradable container for biodegradation. However, studies have found that the culture medium in the biodegradable container will undergo anaerobic reactions due to excessive humidity, accompanied by the production of toxic and harmful gases, threatening the health of users.

[0004] Therefore, please refer to the Chinese utility model patent with publication number CN219527847U. A biodegradable toilet with a water tray has emerged on the market. By setting a rotatable water tray, urine or flushing water can be collected and guided to the urine box, thereby ensuring the dryness of the biodegradable container and avoiding excessive humidity in the cultured genes and anaerobic reactions that produce toxic and harmful gases. However, the applicant found in the application that the water tray and its auxiliary mechanism would occupy a large amount of space in the biodegradable container, limiting the volume of the biodegradable container, resulting in the need for frequent replacement of the culture medium in the biodegradable container, which seriously affected people's experience of use.

[0005] Solving the above problems has become a top priority. Summary of the invention

[0006] In view of this, the present invention provides a flip-type dry-wet separation structure and a biodegradable toilet.

[0007] The technical solution is as follows:

[0008] The first aspect of the present application relates to a flip-type dry-wet separation structure, comprising a toilet bowl assembly and a flow guide mechanism, wherein the toilet bowl assembly has a large discharge port and a toilet bowl urine guide port located in front of the large discharge port, the toilet bowl assembly has a water receiving tray arranged below the toilet bowl urine guide port, and the water receiving tray is provided with at least one urine discharge hole, and the flow guide mechanism comprises at least one flow guide plate rotatably mounted on the toilet bowl assembly and a flow guide plate control assembly for driving each flow guide plate to rotate;

[0009] When the guide plate control assembly rotates each guide plate to a horizontal position, each guide plate blocks the lower part of the large discharge port and forms a flow channel that can guide the collected liquid to the water receiving tray.

[0010] When the guide plate control assembly rotates each guide plate to a vertical posture, each guide plate together forms a vertically penetrating discharge channel, and the discharge channel is located directly below the large discharge port.

[0011] With the above-mentioned flip-type dry-wet separation structure, when the user defecates, each guide plate rotates to a vertical posture, and the feces can directly fall into the biodegradable container below through the discharge channel, and undergo biodegradation reaction under the action of the culture medium; when the user urinates and flushes after defecation, each guide plate rotates to a horizontal posture, and a part of the user's urine and flushing waste water can be directly discharged to the water receiving tray below it through the urine drainage port of the toilet bowl, and guided to the urine storage device through the urine drainage hole of the water receiving tray, and the rest can be discharged to the flow channel formed by each guide plate below it through the large discharge port, and then Then it is led to the water collecting tray through the flow channel, and then to the urine storage device through the urination hole of the water collecting tray; the entire flip-type dry-wet separation structure can not only achieve complete dry-wet separation, but also reliably collect all liquids when the user urinates and flushes after defecation, thereby ensuring the dryness of the biodegradable container and avoiding anaerobic reactions that produce toxic and harmful gases due to excessive humidity in the culture medium, and the whole can be hidden in the toilet bowl assembly without causing any impact on the installation space of the biodegradable container, thereby greatly extending the frequency of replacing the culture medium and improving the user experience.

[0012] The sliding urinary guide plate and the fixed urinary guide plate work together to catch the urine discharged by the user and transport the urine to the urine box through the urinary guide hole and the urinary guide pipe; the entire toilet wet and dry separation structure occupies very little space in the biodegradable container, and the impact on the space of the biodegradable container is negligible, thereby greatly extending the frequency of culture medium replacement and improving people's user experience.

[0016] In some embodiments, the water receiving tray is gradually tilted downward from the back to the front, and each urination hole is adjacent to the front edge of the water receiving tray;

[0017] When the deflector control assembly rotates the two deflectors to a lateral posture, the two deflectors gradually tilt downward from the rear to the front.

[0018] In some embodiments, the rear edge of the water receiving tray extends upward to form a water receiving tray water retaining wall;

[0019] When the guide plate control assembly rotates the two guide plates to a horizontal posture, the leading edges of the two guide plates extend downward to form guide plate water-guiding walls, the trailing edges of the two guide plates extend upward to form guide plate water-retaining walls, and the guide plate water-guiding wall of the guide plate located in front of the large discharge port protrudes in front of the water-retaining wall of the water receiving tray, and the guide plate water-guiding wall of the guide plate located behind the large discharge port protrudes in front of the guide plate water-retaining wall of the guide plate located in front of the large discharge port.

[0020] In some embodiments, one of the guide plates is rotatably mounted on the toilet bowl assembly via a driving shaft, and the other guide plate is rotatably mounted on the toilet bowl assembly via a follower pin shaft, and has a rotating connecting shaft that rotates synchronously therewith, the rotating connecting shaft is arranged in parallel on a side of the follower pin shaft close to an adjacent guide plate, and a two-link assembly is arranged at any one end or both ends of the driving shaft;

[0047] The present invention is further described below in conjunction with embodiments and drawings.

[0048] Embodiment 1:

[0049] like Figure 1-Figure 5 , Figure 7 and Fig. 9 As shown, a flip-type dry-wet separation structure mainly includes a toilet bowl assembly and a diversion mechanism.

[0050] Among them, the toilet bowl assembly can be composed of one part or multiple parts. In the present embodiment, the toilet bowl assembly is preferably composed of a toilet bowl 2 and a toilet bowl mounting seat 13. The toilet bowl 2 is mounted on the top of the toilet bowl mounting seat 13. The toilet bowl 2 of the present embodiment can be mounted on the toilet bowl mounting seat 13 in a fixed manner or in a detachable manner. The toilet bowl 2 and the toilet bowl mounting seat 13 can be lifted as a whole.

[0051] The bottom of the toilet bowl 2 of the toilet bowl assembly is provided with a large discharge port 2a and a toilet bowl urine guide port 2b located in front of the large discharge port 2a. Specifically, the large discharge port 2a is provided at the rear of the bottom of the toilet bowl 2, and the front of the bottom of the toilet bowl 2 is concave to form a urine guide groove 2c, and the toilet bowl urine guide port 2b is located at the lowest point of the urine guide groove 2c.

[0052] Most of the user's urine flows to the bedpan catheter port 2b, and a small part flows to the large discharge port 2a. Most of the waste water after the user flushes flows to the large discharge port 2a, and a small part flows to the bedpan catheter port 2b. The user's feces falls into the biodegradable container 3 below through the large discharge port 2a.

[0053] In this embodiment, a water receiving tray 13c is integrally formed on the toilet bowl mounting base 13 of the toilet bowl assembly, and the water receiving tray 13c is arranged below the urine guiding port 2b of the toilet bowl. Therefore, the liquid flowing out of the urine guiding port 2b of the toilet bowl will be completely collected by the water receiving tray 13c, and then, since at least one urine discharge hole 13c1 is provided on the water receiving tray 13c, the liquid collected in the water receiving tray 13c is discharged to the urine storage device through each urine discharge hole 13c1.

[0054] In this embodiment, the guide mechanism includes at least one guide plate 15 rotatably mounted on the toilet bowl assembly and a guide plate control assembly for driving each guide plate 15 to rotate, wherein each guide plate 15 is preferably mounted on the toilet bowl 2.

[0055] When the guide plate control assembly rotates each guide plate 15 to a horizontal posture, each guide plate 15 jointly blocks the bottom of the large discharge port 2a, and each guide plate 15 jointly constitutes a flow channel that can guide the collected liquid to the water receiving tray 13c; when the guide plate control assembly rotates each guide plate 15 to a vertical posture, each guide plate 15 jointly constitutes a discharge channel 16 that runs through from top to bottom, and the discharge channel 16 is located directly below the large discharge port 2a.

[0056] Therefore, when the user defecates, each guide plate 15 rotates to a vertical posture, and the feces can directly fall into the biodegradable container 3 below through the discharge channel 16, and undergo a biodegradation reaction under the action of the culture medium; when the user urinates or flushes after defecation, each guide plate 15 rotates to a horizontal posture, and a part of the user's urine and flushing waste water can be directly discharged to the water receiving tray 13c below it through the urine drainage port 2b of the toilet bowl, and guided to the urine storage device through the urine discharge hole 13c1 of the water receiving tray 13c, and the rest can be discharged to the flow channel jointly formed by the guide plates 15 below it through the large discharge port 2a. Then it is guided to the water receiving tray 13c through the flow channel, and then guided to the urine storage device through the urination hole 13c1 of the water receiving tray 13c; the entire flip-type dry-wet separation structure can not only achieve complete dry-wet separation, but also reliably collect all liquids when the user urinates and flushes after defecation, thereby ensuring the dryness of the biodegradable container and avoiding anaerobic reactions that produce toxic and harmful gases due to excessive humidity in the culture medium, and the whole can be hidden in the toilet bowl assembly without causing any impact on the installation space of the biodegradable container, thereby greatly extending the replacement frequency of the culture medium and improving the user experience.

[0057] It should be pointed out that the guide plate 15 can be one or more, as long as the above functions can be achieved.

[0058] In this embodiment, there are preferably two guide plates 15, which can be rotated downward to a vertical position away from each other under the drive of the guide plate control assembly, and can also be rotated to a horizontal position close to each other under the drive of the guide plate control assembly. Compared with the case of one guide plate 15, the vertical space occupied can be reduced in the vertical position, so that the volume of the biodegradable container 3 is as large as possible; compared with the case of more guide plates 15, it is not only easy to synchronously control, making the structure of the guide plate control assembly simple, reliable and durable, but also the overall cost is lower and easy to assemble.

[0059] In this embodiment, one of the guide plates 15 is rotatably mounted at the front of the large discharge port 2a, and the other guide plate 15 is rotatably mounted at the rear of the large discharge port 2a. At the same time, when the guide plate control assembly rotates both guide plates 15 to a horizontal posture, the height of the guide plate 15 located at the front of the large discharge port 2a is higher than the height of the water receiving tray 13c, and the front edge of the guide plate 15 protrudes forward to between the front edge and the rear edge of the water receiving tray 13c, and the height of the guide plate 15 located at the rear of the large discharge port 2a is higher than the height of the guide plate 15 located at the front of the large discharge port 2a, and the front edge of the guide plate 15 located at the rear of the large discharge port 2a protrudes forward to between the front edge and the rear edge of the guide plate 15 located at the front of the large discharge port 2a. Through the above design, the two guide plates 15 and the water receiving tray 13c are arranged in a stepped manner, which can not only reliably collect the liquid discharged from the large discharge port 2a, but also enable the collected liquid to flow stably to the water receiving tray 13c. At the same time, the flipping process of the two guide plates 15 is not prone to interference and jamming, ensuring the stability and smoothness of the cooperation.

[0060] Furthermore, the hinged positions of the two guide plates 15 leave a distance between the front edge and the rear edge of the large discharge port 2a, so that when the two guide plates 15 are in a vertical posture, the width of the discharge channel 16 formed by them is greater than the width of the large discharge port 2a, thereby preventing the feces discharged by the user from soiling the guide plates 15.

[0061] Furthermore, the water receiving tray 13c gradually tilts downward from the back to the front, and each urination hole 13c1 is adjacent to the front edge of the water receiving tray 13c. At the same time, when the guide plate control assembly rotates the two guide plates 15 to the horizontal posture, the two guide plates 15 gradually tilt downward from the back to the front. Through the above design, the two guide plates 15 and the water receiving tray 13c have a slope, and each urination hole 13c1 is adjacent to the front edge of the water receiving tray 13c, which can avoid liquid residue on it, thereby avoiding the problem of scale accumulation and odor after long-term use.

[0062] Furthermore, the water receiving tray 13c is recessed adjacent to the front edge to form a confluence groove 13c3, and each urination hole 13c1 is arranged at the bottom of the confluence groove 13c3. Through such a design, the liquid collected by the water receiving tray 13c can first be converged into the confluence groove 13c3 and then discharged through the urination holes 13c1, which can effectively solve the problem of liquid residue around each urination hole 13c1.

[0063] Furthermore, the bottom of the water receiving tray 13c is integrally formed with urination tubes 13c4 corresponding to the urination holes 13c1, each urination tube 13c4 extends downward, and the inner hole of each urination tube 13c4 constitutes the urination hole 13c1. This design facilitates docking with the urine storage device to avoid leakage.

[0064] Furthermore, the rear edge of the water receiving tray 13c extends upward to form a water receiving tray water retaining wall 13c2; at the same time, when the guide plate control assembly rotates the two guide plates 15 to a horizontal posture, the front edges of the two guide plates 15 extend downward to form a guide plate water guide wall 15a, the rear edges of the two guide plates 15 extend upward to form a guide plate water retaining wall 15b, and the guide plate water guide wall 15a of a guide plate 15 located in front of the large discharge port 2a protrudes to the front of the water receiving tray water retaining wall 13c2, and the guide plate water guide wall 15a of a guide plate 15 located behind the large discharge port 2a protrudes to the front of the guide plate water retaining wall 15b of a guide plate 15 located in front of the large discharge port 2a. Through such a design, not only can the problem of liquid overflow between the water receiving tray 13c and the two guide plates 15 when collecting liquid be effectively avoided, but also the problem of liquid leakage at their respective connections can be avoided.

[0065] See also Figure 4 and Figure 5 One of the guide plates 15 is rotatably mounted on the toilet bowl 2 of the toilet bowl assembly through an active rotating shaft 15c, and the other guide plate 15 is rotatably mounted on the toilet bowl 2 of the toilet bowl assembly through a follower pin shaft 15d, and has a rotating connecting shaft 15e that rotates synchronously therewith, and the rotating connecting shaft 15e is arranged in parallel on a side of the follower pin shaft 15d close to the adjacent guide plate 15, and a two-link assembly is arranged at any one end or both ends of the active rotating shaft 15c. The method of arranging the two-link assembly at both ends is more stable and reliable, and the method of arranging the two-link assembly at only one end is more cost-effective.

[0066] Among them, the two-link assembly includes an active link 21 and a driven link 22, one end of the active link 21 is synchronously rotated and installed on the corresponding end of the active rotating shaft 15c, the other end of the active link 21 is hinged to one end of the driven link 22, and the other end of the driven link 22 is hinged to the corresponding end of the rotating connecting shaft 15e; the guide plate control assembly can drive the active rotating shaft 15c to rotate.

[0067] Therefore, when the guide plate control assembly drives the active shaft 15c to rotate, not only the guide plate 15 on which the active shaft 15c is installed will rotate, but the active shaft 15c can also drive the other guide plate 15 to rotate through the two-link assembly. By driving the active shaft 15c to rotate forward or reversely through the guide plate control assembly, the two guide plates 15 can be synchronously rotated to a horizontal posture or synchronously rotated to a vertical posture, and the structure is simple and reliable.

[0068] Since the toilet bowl assembly of the present embodiment is preferably composed of a toilet bowl mounting base 13 and a toilet bowl 2 mounted thereon, in order to facilitate user operation, the deflector control assembly includes a lever 17, a lever shaft 18, a driving bevel gear 19 and a driven bevel gear 20. The upper end of the vertically arranged lever shaft 18 passes upward through the toilet bowl 2 of the toilet bowl assembly and is synchronously rotatably installed with the lever 17. The driving bevel gear 19 is synchronously rotatably installed on one end of the lever shaft 18 that passes downward into the toilet bowl 2. The driven bevel gear 20 is synchronously rotatably installed on one end of the driving shaft 15c.

[0069] It should be pointed out that the lever 17 can also be set on the side wall of the toilet bowl mounting seat 13. In this case, the lever shaft 18 is arranged horizontally, and the lever 17 is installed on the end of the lever shaft 18 that passes through the toilet bowl mounting seat 13 so as to rotate synchronously, and the driving bevel gear 19 is installed on the end of the lever shaft 18 that passes through the toilet bowl mounting seat 13 so as to rotate synchronously. Of course, the driving bevel gear 19 and the driven bevel gear 20 can also adopt other methods commonly used by those skilled in the art, such as cylindrical gears.

[0070] Furthermore, since the active rotating shaft 15c is subjected to greater force, in order to ensure the stability and reliability of its cooperation with the counterpart, the active rotating shaft 15c does not adopt a conventional cylindrical structure, but preferably adopts a rotating shaft with a triangular, square or polygonal cross section.

[0071] Embodiment 2:

[0072] See also Figure 5-Figure 16 A biodegradable toilet comprises a toilet body 1 and the flip-type dry-wet separation structure of Example 1.

[0073] A biodegradable container 3 with an open top is arranged in the toilet body 1. Specifically, the toilet body 1 forms a container mounting groove 1a with an open top, and the container mounting groove 1a is adapted to the biodegradable container 3. The biodegradable container 3 is installed in the container mounting groove 1a.

[0074] The biodegradable container 3 can be fixedly installed in the container installation groove 1a, or can be detachably installed in the container installation groove 1a. The biodegradable container 3 of this embodiment is preferably detachably installed in the container installation groove 1a, so that the biodegradable container 3 can be taken out separately for cleaning. Since the top of the container installation groove 1a of the toilet body 1 of this embodiment has an opening, the biodegradable container 3 is preferably installed in the container installation groove 1a in an upper and lower manner.

[0075] The toilet bowl assembly is installed on the top of the toilet body 1, that is, the toilet bowl 2 is installed at the notch position of the container mounting groove 1a and is located above the biodegradable container 3. Therefore, by lifting the toilet bowl assembly upward, the container mounting groove 1a of the toilet body 1 can be exposed to the outside, and the toilet bowl assembly is placed on the top of the toilet body 1, and the biodegradable toilet can be used normally.

[0076] Furthermore, the top of the toilet body 1 and the bottom of the toilet bowl mounting seat 13 are provided with mutually adapted positioning structures, so that the installation position of the toilet bowl mounting seat 13 on the top of the toilet body 1 can be accurately defined.

[0077] At the same time, a toilet cover 11 that can rotate relative to the toilet bowl mounting seat 13 is installed on the rear outer edge of the top thereof. The toilet cover 11 can be opened or closed on the toilet bowl 2, so that when the biodegradable toilet is not in use, the toilet cover 11 can be closed on the toilet bowl 2 to cover dust and maintain beauty.

[0078] In this embodiment, the large discharge port 2a is located directly above the top opening of the biodegradable container 3. When the large discharge port 2a is not blocked, the feces discharged by the user can smoothly fall into the biodegradable container 3. At the same time, each urination hole 13c1 can guide the liquid collected by the water receiving tray 13c to the urine storage device.

[0079] Specifically, the interior of the toilet body 1 is a urine storage chamber 1b with a hollow cavity structure. The urine storage chamber 1b is a urine storage device, so that liquids such as urine and cleaning waste water can be stored in the urine storage chamber 1b. The toilet body 1 is provided with at least one urine storage chamber inlet 1b1 connected to the urine storage chamber 1b. The number of the urine storage chamber inlets 1b1 is the same as the number of the urination holes 13c1. Each urination hole 13c1 is connected to the corresponding urine storage chamber inlet 1b1, that is, each urination tube 13c4 is inserted downward into the corresponding urine storage chamber inlet 1b1.

[0080] Therefore, in this embodiment, a urine storage cavity 1b for storing liquids such as urine is directly integrally formed inside the side wall and / or bottom wall of the toilet body 1, so that not only can a large-sized biodegradable container 3 still be accommodated therein, the frequency of pouring and replacing the culture medium in the biodegradable container 3 is very low, which improves the user experience, and the biodegradable toilet has almost no major changes in its external dimensions, and the installation location of the biodegradable toilet can be flexibly selected, which is particularly suitable for use scenarios with extremely limited internal space such as RVs and yachts.

[0081] A urine discharge port 1b3 connected to the urine storage chamber 1b is provided at the bottom of the toilet body 1. The urine discharge port 1b3 can be opened or closed, that is, when the urine storage chamber 1b is full of liquid and needs to be emptied, the urine discharge port 1b3 is opened; when the biodegradable toilet is used normally, the urine discharge port 1b3 is closed.

[0082] In this embodiment, the bottom of the toilet body 1 is concavely formed with a urination component accommodating groove 1d, and the urine discharge port 1b3 is provided on the groove wall of the urination component accommodating groove 1d. A valve 4 and a bendable urination tube 5 are provided in the urination component accommodating groove 1d, and one end of the valve 4 is connected to the urine discharge port 1b3, and the other end is connected to one end of the urination tube 5. Therefore, when the biodegradable toilet is used normally, the valve 4 is in a closed state. When the urine storage cavity 1b is full of liquid and needs to be emptied, the valve 4 is opened, and the liquid in the urine storage cavity 1b will be discharged outward through the urination tube 5.

[0083] The urination tube 5 of this embodiment is bendable and is usually hidden in the urination component receiving groove 1d, thereby ensuring the overall beauty. When the urine storage cavity 1b needs to be drained, the urination tube 5 can be adaptively bent according to actual conditions, which is very flexible and convenient.

[0084] The toilet body 1 of this embodiment often needs to be moved to a designated position to discharge the liquid in the urine storage cavity 1b. Therefore, in order to improve the user's convenience, the toilet body 1 of this embodiment is preferably made of high-strength plastic, which not only realizes lightweight design but also ensures its own structural strength.

[0085] Furthermore, two roller mounting grooves 1e are formed on the rear outer edge of the bottom of the toilet body 1, and rollers 12 are installed in the two roller mounting grooves 1e to protrude outward, which will not affect the stability and reliability of the placement and use of the biodegradable toilet, and is convenient for users to move, thereby improving the convenience of daily use. At the same time, in order to facilitate lifting, buckle grooves 1f are formed on the left and right outer walls of the toilet body 1, thereby providing a grip point for the user's hand, thereby improving the convenience of lifting the toilet.

[0086] Furthermore, in order to prevent the toilet body 1 from leaking due to collision and damage, the wall of the urine storage chamber 1b of this embodiment adopts a double-layer design, that is, a urine box liner 1c is also provided on the wall of the urine storage chamber 1b. However, it should be pointed out that there is no problem if the urine storage chamber 1b of this embodiment is not provided with the urine box liner 1c, as long as the urine storage chamber 1b is a leak-proof sealed structure.

[0087] There are two installation methods for the urine box liner 1c:

[0088] Installation method 1 of the urine box liner 1c: The urine box liner 1c is fixedly installed on the wall of the urine storage cavity 1b. Specifically, the urine box liner 1c can be fixedly installed on the wall of the urine storage cavity 1b by bonding, or it can be integrally formed with the toilet body 1 by two-color injection molding. Of course, other existing technical means known to those skilled in the art can also be used. Among them, for the two-color injection molding process, the toilet body 1 preferably uses high-strength hard plastic, and the urine box liner 1c preferably uses flexible plastic that is elastic and not easy to break.

[0089] The second installation method of the urine box liner 1c: the urine box liner 1c can be detachably installed on the wall of the urine storage cavity 1b. For example, the toilet body 1 is fixed as a whole by two injection molded parts through ultrasonic welding. Before ultrasonic welding, the urine box liner 1c is first installed in one of the injection molded parts, and then the other injection molded part is buckled, and finally ultrasonic welding is performed. In addition to ultrasonic welding, other existing technical means known to those skilled in the art can also be used to connect the two injection molded parts.

[0090] A flushing water inlet 1b2 connected to the urine storage chamber 1b is provided on the top of the toilet body 1. The flushing water inlet 1b2 can be opened or closed by a plug 6, so that when the urine storage chamber 1b needs to be cleaned, the plug 6 can be removed and clean water or cleaning agent can be added to the urine storage chamber 1b through the flushing water inlet 1b2. After cleaning, the flushing water inlet 1b2 can be sealed with the plug 6.

[0091] Furthermore, the inner end of the plug 6 is recessed to form a plug groove 6a, on which a floating block lifting guide cylinder 7 protruding from the inner end of the plug 6 can be detachably installed. The floating block lifting guide cylinder 7 is a cylindrical structure with a bottom plugged. When the plug 6 blocks the flushing water inlet 1b2, the floating block lifting guide cylinder 7 is vertically inserted into the urine storage cavity 1b. In addition, at least one guide cylinder water permeable port 7a is provided on the floating block lifting guide cylinder 7. A floating block 8 that can rise and fall with the liquid level is installed in the floating block lifting guide cylinder 7. An induction body 9 is installed on the top of the floating block 8. An induction body detection device 10 adapted to the induction body 9 is installed immediately above the plug 6.

[0092] Therefore, when the liquid in the urine storage chamber 1b is at a high level, the float 8 can adaptively rise and fall with the liquid level. When the liquid in the urine storage chamber 1b reaches the alarm position, the float 8 is also at a high position, and the sensor detection device 10 can sense the sensor 9 and then issue an alarm (for example, the alarm light is on) to prompt the user to empty the urine storage chamber 1b.

[0093] In order to improve the sealing performance of the plug 6 and avoid leakage, a waterproof sealing ring 14 is also installed on the outer peripheral surface of the plug 6. When the plug 6 is installed on the flushing water inlet 1b2, the waterproof sealing ring 14 is sealed between the plug 6 and the flushing water inlet 1b2 with an interference fit.

[0094] The induction body 9 may be a magnet, and the induction body detection device 10 may then use a Hall sensor; the induction body 9 may also be made of a corrosion-resistant metal material, and the induction body detection device 10 may then use a proximity sensor.

[0095] Furthermore, the guide tube water permeable openings 7a are all strip-shaped slit structures extending upward from the bottom of the float lifting guide tube 7, so that the water level inside the float lifting guide tube 7 can change in time with the liquid level in the urine storage cavity 1b, thereby improving the detection accuracy.

[0096] In order to further improve the detection accuracy, each guide tube water permeable port 7a is evenly distributed along the circumferential direction on the circumferential side wall of the floating block lifting guide tube 7, thereby further improving the response speed of the water level inside the floating block lifting guide tube 7 to the change of the liquid level in the urine storage cavity 1b.

[0097] The circuit boards of the biodegradable toilet are all installed inside the toilet bowl mounting seat 13. In order to facilitate the installation of the sensor detection device 10 and ensure the reliability of the sensor detection device 10, the sensor detection device 10 is preferably installed at the bottom of the toilet bowl mounting seat 13. When the toilet bowl mounting seat 13 is placed on the toilet body, the sensor detection device 10 is closely arranged just above the plug 6.

[0098] The toilet bowl mounting seat 13 has a circuit board mounting cavity 13 a and a clean water containing cavity 13 b both of which are cavity structures. The circuit board mounting cavity 13 a and the clean water containing cavity 13 b are located on the left and right sides of the toilet bowl mounting seat 13 respectively.

[0099] The circuit board installation cavity 13a is provided with electrical components such as a circuit board, thereby providing good protection for the electrical components and improving the service life of the electrical components. The inductor detection device 10 is arranged at the bottom of the circuit board installation cavity 13a.

[0100] The clean water accommodating chamber 13b is used to contain clean water, so as to supply water to the nozzle of the smart seat ring. Specifically, a water pump is also provided in the clean water accommodating chamber 13b, and the clean water contained in the clean water accommodating chamber 13b is pressurized by the water pump and supplied to the nozzle of the smart seat ring.

[0101] Further, similar to the urine storage chamber 1b, in order to avoid leakage of the clean water storage chamber 13b due to damage to the toilet bowl mounting seat 13, the cavity wall of the clean water storage chamber 13b of this embodiment adopts a double-layer design, that is: a water tank liner 13b1 is also provided on the cavity wall of the clean water storage chamber 13b. However, it should be pointed out that there is no problem if the clean water storage chamber 13b of this embodiment is not provided with a water tank liner 13b1, as long as the clean water storage chamber 13b is a sealed structure that will not leak. Similarly, the water tank liner 13b1 can also be fixedly installed or detachably installed, depending on actual needs.

[0102] Furthermore, in order to facilitate the filling of clean water into the clean water accommodating chamber 13b, a clean water filling port is provided on the top of the toilet bowl mounting seat 13. Normally, the clean water filling port is sealed by a sealing cover 13b2, and the sealing cover 13b2 is exposed at the top of the toilet bowl 2 for user operation.

[0103] See also Figure 14-16 In the biodegradable container 3 of this embodiment, a stirring kettle 23 extending in the horizontal direction is installed, and the stirring kettle 23 can rotate under the control of a manual driving device 24 and / or an electric driving device 25. That is, in the biodegradable toilet, only a manual driving device 24 can be installed, and the rotation of the stirring kettle 23 in the biodegradable container 3 is controlled by the manual driving device 24; in the biodegradable toilet, only an electric driving device 25 can be installed, and the rotation of the stirring kettle 23 in the biodegradable container 3 is controlled by the electric driving device 25; in the biodegradable toilet, both a manual driving device 24 and an electric driving device 25 can be installed, and the rotation of the stirring kettle 23 in the biodegradable container 3 can be controlled by both the manual driving device 24 and the electric driving device 25.

[0104] See also Fig.15 and Fig.16 The manual drive device 24 is generally integrated and installed on the toilet body 1. When the biodegradable container 3 is installed in the toilet body 1, one end of the stirring kettle 23 is connected to the driving shaft of the manual drive device 24, so that they can rotate synchronously, that is, rotating the rocker arm of the manual drive device 24 can drive the stirring kettle 23 to rotate synchronously with it. When the biodegradable container 3 is taken out of the toilet body 1, one end of the stirring kettle 23 is separated from the driving shaft of the manual drive device 24.

[0105] Furthermore, a rocker arm receiving groove 1h is recessed on the side wall of the toilet body 1, and the rocker arm receiving groove 1h is compatible with the rocker arm of the manual drive device 24. When there is no need to rotate the mixing kettle 23, the rocker arm of the manual drive device 24 can be received in the rocker arm receiving groove 1h, thereby ensuring the overall aesthetic appearance.

[0106] See also Fig.14The electric drive device 25 includes a motor and a reducer, and the motor can drive the stirring kettle 23 to rotate through the reducer. In this embodiment, after removing the rear baffle 1g of the housing of the toilet body 1, it can be clearly seen that the electric drive device 25 is integrated and installed on the outer side wall of the biodegradable container 3. In this embodiment, the easily disassembled rear baffle 1g of the housing can facilitate the maintenance and replacement of the electric drive device 25.
