Description

Technical Field

[0001] The utility model relates to the technical field of toilets, in particular to a biodegradable toilet with an integrated urine box. 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 caring for elderly people with limited mobility where it is inconvenient to collect water or discharge waste.

[0003] Most biodegradable toilets on the market, such as those disclosed in Patent Publication No. EP3816355B1, require a separate urine collection container 28 (i.e., a urine tank) to collect urine discharged by the user. However, due to the extremely limited internal space of a toilet, the separate urine tank can only accommodate a small feces collection container (i.e., a biodegradable container). This results in the culture medium in the biodegradable container needing to be frequently emptied and replaced, resulting in a poor user experience.

[0004] To this end, some biodegradable toilets on the market, such as those disclosed in patent publication number CN111608239A, have an independent urinal 40 (i.e., urine tank) located outside the toilet. This allows the biodegradable toilet to accommodate a large biodegradable container, significantly reducing the frequency of emptying and replacing the culture medium in the biodegradable container. However, for use in scenarios with extremely limited interior space, such as RVs and yachts, the toilet area is typically very small, and the external independent urine tank requires additional space, making it difficult to find a suitable installation location for the urine tank in real-world installations, limiting the promotion and application of this type of biodegradable toilet.

[0005] Solving the above problems has become a top priority. Utility Model Content

[0006] In view of this, the utility model provides a biodegradable toilet with an integrated urine tank.

[0007] The technical solution is as follows:

[0008] The first aspect of the present application relates to a biodegradable toilet with an integrated urine tank, comprising a toilet body, a toilet bowl and a biodegradable container, the toilet body forms a container mounting groove with an open top, the biodegradable container is mounted in the container mounting groove, the toilet bowl is mounted at the opening position of the container mounting groove and is located above the biodegradable container, the interior of the toilet body is a hollow cavity structure, thereby forming a urine storage cavity capable of storing liquid, at least one urine storage cavity inlet communicating with the urine storage cavity is formed on the toilet body, and a large discharge port located directly above the biodegradable container and a toilet urine guide port for guiding liquid to each urine storage cavity inlet are formed on the bottom of the toilet bowl.

[0009] The biodegradable toilet with an integrated urine tank can directly form a urine storage cavity inside the side wall and / or bottom wall of the toilet body for storing urine and other liquids, thereby not only still being able to accommodate a large-sized biodegradable container inside, making the frequency of pouring and replacing the culture medium in the biodegradable container very low and improving the user's experience, but also having almost no change in the external dimensions of the biodegradable toilet, allowing flexible selection of the installation position of the biodegradable toilet, and being particularly suitable for use in scenarios with extremely limited internal space, such as motor homes and yachts.

[0019] In some embodiments, the water permeable openings of the guide tube are evenly distributed along the circumferential direction on the circumferential side wall of the floating block lifting guide tube.

[0020] In some embodiments, the top of the toilet body is detachably covered with a bedpan mounting seat, and a toilet lid that can rotate relative to the top of the bedpan mounting seat is installed on the rear outer edge of the top of the bedpan mounting seat, and the toilet lid can be opened or closed on the bedpan.

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] like Figure 1-Figure 7 As shown, a biodegradable toilet with an integrated urine tank mainly includes a toilet body 1, a toilet bowl 2 and a biodegradable container 3.

[0031] Wherein, the biodegradable container 3 is a box structure with an open top, and the closest to the toilet body 1 is also a box structure with an open top, that is, the toilet body 1 constitutes a container installation groove 1a with an open top, which is matched with the biodegradable container 3, and the biodegradable container 3 is installed in the container installation groove 1a.

[0032] Please see Figure 6 , 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, and the biodegradable container 3 of the embodiment is preferably detachably installed in the container installation groove 1a, so as to facilitate the biodegradable container 3 to be taken out alone for cleaning. Since the top of the container installation groove 1a of the toilet body 1 of the embodiment is open, the biodegradable container 3 is preferably installed in the container installation groove 1a in an up-down manner.

[0033] Please see Figure 1 、 Figure 3 、 Figure 5 and Figure 6 , the toilet bowl 2 is installed at the slot position of the container installation groove 1a and above the biodegradable container 3. Specifically, the top of the toilet body 1 is detachably covered with a toilet bowl mounting seat 13, and the toilet bowl 2 is installed on the top of the toilet bowl mounting seat 13. The toilet bowl 2 of the embodiment can be fixedly installed on the toilet bowl mounting seat 13, or can be detachably installed on the toilet bowl mounting seat 13. Therefore, by lifting the toilet bowl mounting seat 13 upward, the container installation groove 1a of the toilet body 1 can be exposed to the outside, and by placing the toilet bowl mounting seat 13 on the top of the toilet body 1, the biodegradable toilet can be normally used.

[0034] Further, the top of the toilet body 1 and the bottom of the toilet bowl mounting seat 13 are provided with positioning structures matched with each other, so as to accurately define the installation position of the toilet bowl mounting seat 13 on the top of the toilet body 1.

[0035] At the same time, the rear side outer edge of the top of the toilet bowl mounting seat 13 is provided with a toilet cover 11 capable of rotating relative thereto, and the toilet cover 11 can be opened or covered on the toilet bowl 2, so as to cover the toilet cover 11 on the toilet bowl 2 when the biodegradable toilet is not used, thereby achieving the effect of hiding dirt and keeping the appearance beautiful.

[0036] Please see Figures 1-6 , the inside of the toilet body 1 is a hollow cavity structure, and therefore the hollow cavity structure in the inside of the toilet body 1 forms a urine storage cavity 1b capable of storing liquid, so that liquid such as urine and cleaning wastewater can be stored in the urine storage cavity 1b.

[0037] Specifically, the toilet body 1 is provided with at least one urine storage cavity inlet 1b1 communicating with the urine storage cavity 1b, and the basin bottom of the toilet basin 2 is provided with a basin urine guide opening 2b for guiding liquid to each urine storage cavity inlet 1b1, that is, the urine discharged by the user is collected by the toilet basin 2, flows to the basin urine guide opening 2b, and then enters the urine storage cavity 1b through each urine storage cavity inlet 1b1 for storage. At the same time, the basin bottom of the toilet basin 2 is also provided with a large discharge opening 2a located directly above the biodegradable container 3, and the excrement discharged by the user falls into the biodegradable container 3 through the large discharge opening 2a.

[0038] Therefore, the urine storage cavity 1b for storing liquid such as urine is directly and integrally formed in the side wall and / or bottom wall of the toilet body 1, so that not only can a biodegradable container 3 of a large size be accommodated therein, the frequency of pouring and replacing the culture medium in the biodegradable container 3 is very low, the user's use experience is improved, but also the biodegradable toilet has little change in the overall size, and the installation position of the biodegradable toilet can be flexibly selected, which is particularly suitable for use in a house car or a yacht with extremely limited internal space.

[0039] The bottom of the toilet body 1 is provided with a urine discharge opening 1b3 communicating with the urine storage cavity 1b, and the urine discharge opening 1b3 can be opened or closed, that is, when the urine storage cavity 1b is full of liquid and needs to be emptied, the urine discharge opening 1b3 is opened, and when the biodegradable toilet is normally used, the urine discharge opening 1b3 is closed.

[0040] Please refer to Figure 4 and Figure 5 In the embodiment, the bottom of the toilet body 1 is concave to form a urination assembly accommodating groove 1d, the urine discharge opening 1b3 is formed on the groove wall of the urination assembly accommodating groove 1d, a valve 4 and a bendable urination pipe 5 are arranged in the urination assembly accommodating groove 1d, one end of the valve 4 is connected with the urine discharge opening 1b3, and the other end is connected with one end of the urination pipe 5. Therefore, when the biodegradable toilet is normally used, 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 is discharged outward through the urination pipe 5.

[0041] The urination pipe 5 of the embodiment can be bent, and is usually hidden in the urination assembly accommodating groove 1d, so as to ensure the overall appearance, and is adaptively bent according to the actual situation when the liquid in the urine storage cavity 1b needs to be discharged, which is very flexible and convenient.

[0042] The toilet body 1 of the 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 use convenience of the user, the toilet body 1 of the embodiment is preferably made of high-strength plastic, which not only realizes lightweight design, but also guarantees the structural strength of the toilet body 1.

[0043] Further, two roller mounting grooves 1e are recessed on the outer edge of the rear side of the bottom of the toilet body 1, and rollers 12 are outwardly protrudingly mounted in the two roller mounting grooves 1e, which neither affect the stability and reliability of the biodegradable toilet in placement and use, nor hinder the user from moving, thereby improving the convenience in daily use. Meanwhile, in order to facilitate lifting, a buckle groove 1f is recessed on the outer wall of each of the left and right sides of the toilet body 1, thereby providing a grip for the user's hand and improving the convenience in lifting the toilet.

[0044] Further, in order to avoid the problem that the urine storage cavity 1b leaks due to the damage of the toilet body 1 caused by collision, the cavity wall of the urine storage cavity 1b in the embodiment is designed in double layers, that is, the urine tank inner container 1c is further arranged on the cavity wall of the urine storage cavity 1b. It should be pointed out that the urine storage cavity 1b in the embodiment is not provided with the urine tank inner container 1c, which is also not a problem, as long as the urine storage cavity 1b is a sealed structure that will not leak.

[0045] The urine tank inner container 1c has the following two installation modes:

[0046] The first installation mode of the urine tank inner container 1c is that the urine tank inner container 1c is fixedly installed on the cavity wall of the urine storage cavity 1b. Specifically, the urine tank inner container 1c can be fixedly installed on the cavity wall of the urine storage cavity 1b by adhesion, or can be integrally formed with the toilet body 1 by double-color injection molding, or can be connected by other existing technical means known to those skilled in the art. For the double-color injection molding process, the toilet body 1 is preferably made of high-strength hard plastic, and the urine tank inner container 1c is preferably made of flexible plastic that is elastic and not easy to break.

[0047] The second installation mode of the urine tank inner container 1c is that the urine tank inner container 1c is detachably installed on the cavity wall of the urine storage cavity 1b. For example, the toilet body 1 is fixed as a whole by ultrasonic welding of two injection molded parts. Before ultrasonic welding, the urine tank inner container 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.

[0048] Please refer to Figure 5-Figure 7 The top of the toilet body 1 is provided with a flushing water inlet 1b2 communicating with the urine storage cavity 1b, which can be opened or closed by a plug 6, so that when it is necessary to clean the urine storage cavity 1b, the plug 6 can be removed, and the urine storage cavity 1b can be filled with clean water or cleaning agent through the flushing water inlet 1b2, and after cleaning, the flushing water inlet 1b2 can be plugged by the plug 6.

[0049] Furthermore, the inner end of the plug 6 is recessed to form a plug groove 6a. A float lifting guide cylinder 7, which protrudes from the inner end of the plug 6, is removably mounted on the plug groove 6a. The float lifting guide cylinder 7 is a cylindrical structure with a sealed bottom. When the plug 6 seals the flushing water inlet 1b2, the float lifting guide cylinder 7 is vertically inserted into the urine storage chamber 1b. Furthermore, the float lifting guide cylinder 7 is provided with at least one guide cylinder water permeable opening 7a. A float 8, which can rise and fall with the liquid level, is mounted in the float lifting guide cylinder 7. An inductor 9 is mounted on the top of the float 8. An inductor detection device 10, compatible with the inductor 9, is mounted immediately above the plug 6.

[0050] 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 lights up) to prompt the user to empty the urine storage chamber 1b.

[0051] The induction body 9 may be a magnet, and the induction body detection device 10 may accordingly be 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 accordingly be a proximity sensor.

[0052] Furthermore, the guide tube water permeable openings 7a are all strip-shaped slit structures extending upward from the bottom of the floating block lifting guide tube 7, so that the water level inside the floating block lifting guide tube 7 can change in time with the liquid level in the urine storage cavity 1b, thereby improving the detection accuracy.

[0053] In order to further improve the detection accuracy, the water permeable openings 7a of each guide tube are 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.

[0054] See Figure 5 The circuit boards of the biodegradable toilet are all installed inside the toilet bowl mounting base 13. To facilitate the installation of the sensor detection device 10 and ensure its reliability, the sensor detection device 10 is preferably installed at the bottom of the toilet bowl mounting base 13. When the toilet bowl mounting base 13 is placed on the toilet body, the sensor detection device 10 is tightly placed directly above the plug 6.

[0055] See Figure 3 and Figure 5 The interior of the toilet bowl mounting seat 13 has a circuit board mounting cavity 13a and a clean water accommodating cavity 13b, both of which are cavity structures. The circuit board mounting cavity 13a and the clean water accommodating cavity 13b are respectively located on the left and right sides of the toilet bowl mounting seat 13.

[0056] 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 their service life.

[0057] The clean water accommodating chamber 13b is used to hold 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 held in the clean water accommodating chamber 13b is pressurized by the water pump and supplied to the nozzle of the smart seat ring.

[0058] Furthermore, similar to the urine storage chamber 1b, to prevent leakage from the clean water storage chamber 13b due to damage to the toilet bowl mounting base 13, the clean water storage chamber 13b of this embodiment adopts a double-layer design. That is, the wall of the clean water storage chamber 13b is also provided with a water tank liner 13b1. However, it should be noted that the clean water storage chamber 13b of this embodiment can be installed without the water tank liner 13b1, as long as the clean water storage chamber 13b is a leak-proof sealed structure. Similarly, the water tank liner 13b1 can also be installed in a fixed manner or in a removable manner, depending on actual needs.

[0059] See Figure 7 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.

[0060] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
