Description

Technical Field

[0001] This utility model belongs to the field of camping equipment technology, and more specifically, it relates to a toilet in a camping vehicle. Background Technology

[0002] As people's living standards improve, more and more people are choosing to travel by campervan. A toilet is an indispensable piece of equipment in campervans. However, most existing campervan toilets use a direct-flush or waste-storage design, and their flushing method is similar to that of ordinary household toilets, consuming a large amount of water with each flush. Since campervans have limited water tank capacity, frequent refills are not only inconvenient but may also affect normal use due to difficulties in obtaining water. Furthermore, finding suitable water sources in remote areas is not easy. Therefore, the widespread adoption of existing campervan toilets is difficult.

[0003] For example, the patent with announcement number "CN218558691U" discloses a field camping vehicle. A toilet is fixedly connected to the right side of the rear of the extended compartment. The toilet is equipped with a toilet and a shower. The bed, toilet and simple kitchen facilities inside the field camping vehicle improve the soldiers' continuous combat capability and provide toilet and shower functions.

[0004] However, in actual use, the toilets have the following shortcomings: 1. The bumps and jolting during the campervan's journey make the toilet's drainpipe prone to waste accumulation and blockage. Once blocked, the cleaning process is extremely cumbersome, requiring professional repairs, which seriously affects the normal use of the campervan. 2. The relatively enclosed space of the campervan makes it difficult to deal with the odor from the existing toilets, which can quickly permeate the entire compartment, greatly affecting the air quality and passenger comfort. Currently, many campervan toilets rely solely on simple sealing measures, which are insufficient to effectively control odor dissipation. 3. Due to the limited interior space of the campervan, the installation and layout of the toilets are relatively fixed and occupy too much space, resulting in the compression of space in other functional areas of the vehicle, affecting the overall space utilization rate. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a camper toilet, in which all components are integrated into the toilet base, occupying little space, and solid excrement is treated by biomass fermentation, while liquid excrement is centrally stored and discharged, reducing dependence on external sewage facilities, and making it suitable for use in confined environments such as camper vehicles.

[0006] The campervan toilet includes a toilet base, a toilet trough rotatably connected to the upper part of the toilet base, a liquid collection hopper for receiving liquid excrement and a waste trough for receiving solid excrement inside the toilet trough, a waste passage on the waste trough, and a removable hopper and a liquid storage tank inside the toilet base. The hopper is located below the toilet trough and corresponds to the waste passage. The liquid collection hopper has a liquid outlet that communicates with the liquid storage tank.

[0007] Preferably, a toilet seat is rotatably connected to one end of the top of the toilet base, and the toilet bowl is fixedly installed at the bottom of the toilet seat.

[0008] Preferably, a toilet seat is rotatably connected to the toilet base, and the toilet seat is located above the toilet seat.

[0009] Preferably, the toilet bowl is provided with a cover plate that can block the defecation passage.

[0010] Preferably, the toilet base has handles on both sides and a hollowed-out base plate at the bottom.

[0011] Preferably, the liquid storage tank is slidably disposed on the inner bottom of the toilet base, and an installation port for removing the liquid storage tank is provided on either side of the toilet base.

[0012] Preferably, the hopper is rotatably connected to a stirring mechanism for stirring solid excrement, and the toilet base is provided with a driving device for driving the stirring mechanism. The driving device includes a power mechanism, a first end face tooth and a second end face tooth that are engaged with each other. The second end face tooth is fixedly connected to one end of the stirring mechanism that extends out of the hopper. The power mechanism drives the first end face tooth to rotate, and the first end face tooth is provided with a fork assembly that drives it to slide.

[0013] Preferably, the fork assembly includes a fixed base, which is fixedly connected to the toilet base. A power mechanism is fixedly installed on the fixed base, and a drive wheel is fixedly connected to the output end of the power mechanism. A drive shaft is rotatably connected to the fixed base, and a driven wheel that is rotatably connected to the drive wheel is provided on the drive shaft. An end face tooth is provided on the drive shaft and can slide along the axial direction of the drive shaft. An elastic component is provided between the end face tooth and the fixed base. A fork is provided on the end face tooth, and the middle part of the fork is rotatably connected to the fixed base. A connecting component is provided at the end of the fork away from the end face tooth, and the other end of the connecting component extends out of the toilet base.

[0014] Preferably, the toilet base is provided with at least one reversing component for reversing the connecting components.

[0015] Preferably, the toilet base has an inspection port on the side near the power mechanism, and a rear cover plate is fixedly connected to the inspection port; a fan is provided on the toilet base, the air inlet of the fan is connected to the hopper, and the air outlet of the fan extends out of the toilet base.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model collects excrement by using a solid-liquid separation method through a liquid collection hopper and a waste trough, avoiding the generation of odors from mixed fermentation. Combined with a fan to accelerate air circulation in the silo, it further reduces odor emission. At the same time, after the solid excrement falls into the silo, it can be mixed with biomass filler and fermentation bacteria. The stirring mechanism promotes fermentation, reduces odor, and facilitates composting.

[0018] 2. The hopper and liquid storage tank can be removed, making it convenient for users to clean up solid waste or discharge liquids, ensuring the toilet can continue to function normally. The drive device inside the toilet transmits power through the interlocking of end face teeth one and end face teeth two. Pulling the connecting component can disconnect the interlocking, making it easy to remove the hopper and stirring mechanism for cleaning or replacement of biomass filler.

[0019] 3. All components of this utility model are integrated into the toilet base, occupying little space and suitable for use in confined environments such as campervans. Furthermore, solid waste is treated through biomass fermentation, while liquid waste is centrally stored and discharged, reducing reliance on external sewage facilities. Therefore, this utility model does not need to be fixedly installed in a certain place on the campervan and can be moved as needed, greatly saving the internal space of the campervan.

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

[0030] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figures 1 to 8As shown, the campervan toilet includes a toilet base 2, which serves as the basic support for the entire toilet and provides a mounting base for other components. A toilet bowl 5 is rotatably connected to the upper part of the toilet base 2, allowing the toilet bowl 5 to be flipped and lifted. This means that the toilet bowl 5 can be rotated for cleaning, maintenance, or replacement of internal components, making it easy for operators to access its internal structure. The toilet bowl 5 contains a collection hopper 502 for receiving liquid waste and a waste collection trough 503 for receiving solid waste. The collection hopper 502 and waste collection trough 503 separate and collect liquid and solid waste, facilitating biomass fermentation of the solid waste. This effectively reduces odors produced by the fermentation of mixed waste and makes cleaning easier. The toilet bowl 503 has a waste passage 504, and the toilet base 2 has a removable hopper 6. The hopper 6 is used to collect and temporarily store solid excrement. In this embodiment, after the toilet bowl 5 is flipped over and lifted, the hopper 6 can be removed from the top of the toilet base 2 for cleaning or replacement to ensure the toilet can continue to function normally. The hopper 6 is located below the toilet bowl 5 and corresponds to the waste passage 504. The waste passage 504 provides a foundation for solid excrement to fall accurately from the toilet bowl 503 into the hopper 6, ensuring that the solid excrement can smoothly and directly enter the hopper 6 for fermentation, preventing excrement from accumulating and clogging in the toilet bowl 503, and ensuring the normal use of the toilet. The liquid collection hopper 502 has a liquid outlet 501, which is connected to the liquid storage tank 3 through a connecting pipe. The liquid storage tank 3 can be installed inside the toilet base 2 or placed outside the toilet base 2.

[0032] The outlet 501 ensures that liquid waste is collected promptly and smoothly into the storage tank 3, preventing liquid from overflowing or remaining in the collection hopper 502 and maintaining the cleanliness of the toilet bowl. The storage tank 3 is used to store liquid waste, and its removable design facilitates centralized disposal of the waste. In this embodiment, the storage tank 3 has an inlet / outlet 301, and a connecting pipe is inserted into the inlet / outlet 301. To prevent odor emissions, a sealing cap is provided on the inlet / outlet 301. The connecting pipe is a flexible hose, and the connecting pipe is press-fitted with the hole on the sealing cap.

[0033] The toilet base 2 is rotatably connected to the toilet seat 4 at one end, which provides a comfortable place for the user to use. The toilet bowl 5 is fixedly set at the bottom of the toilet seat 4, so that the toilet bowl 5 and the toilet seat 4 form a whole, which is more convenient to use and operate, and ensures the stability of the position between the parts.

[0034] A toilet seat 1 is rotatably connected to the toilet base 2. During installation, the rotation axis of the toilet seat 1 is coaxial with the rotation axis of the toilet seat 4, and the toilet seat 1 is located above the toilet seat 4. The toilet seat 1 can be closed when the toilet is not in use, serving as a cover and protection to prevent dust and debris from falling into the toilet. It also effectively reduces the emission of odors from inside the toilet into the external environment, keeping the air inside the campervan fresh.

[0035] The toilet bowl 5 is equipped with a cover that can block the defecation passage 504. When the defecation function is not in use, the cover can block the defecation passage 504 to further prevent odor from escaping and to prevent debris from accidentally falling into the defecation passage 504; when the defecation function is needed, the cover can be opened to ensure that the excrement can pass smoothly through the defecation passage 504 into the hopper 6.

[0036] The toilet base 2 has handles 201 on both sides, which facilitate users in carrying and moving the toilet. The handles 201 provide a reliable grip, especially when the toilet needs to be removed from the campervan for cleaning or maintenance. The bottom of the toilet base 2 has a perforated base plate 203, which helps with air circulation inside the toilet, preventing bacterial growth due to moisture and other factors. It also reduces the overall weight of the toilet, making it easier to move and install.

[0037] The liquid storage tank 3 is slidably mounted on the inner bottom of the toilet base 2, and an installation port 204 for removing the liquid storage tank 3 is provided on either side of the toilet base 2. The sliding design of the liquid storage tank 3 makes it easy for users to remove and push it into the toilet base 2, and the installation port 204 provides a channel for removing the liquid storage tank 3, facilitating users to clean the liquid storage tank 3, drain liquid waste, and perform other operations, thus improving user convenience.

[0038] A stirring mechanism 8 is rotatably connected inside the hopper 6. This stirring mechanism 8 is existing technology and commercially available; its structure will not be described in detail here. The stirring mechanism 8 can agitate the collected solid excrement, ensuring thorough mixing with the biomass filler and fermentation bacteria within the hopper 6. This facilitates subsequent composting and prevents excrement from accumulating and clumping within the hopper 6, thus avoiding blockages. The toilet base 2 contains a drive unit 7 that powers the stirring mechanism 8.

[0039] Specifically, such as Figure 7As shown, the drive device 7 includes a power mechanism 704, a first end face tooth 705 and a second end face tooth 706 that engage with each other. The power mechanism 704 is a geared motor. The second end face tooth 706 is fixedly connected to one end of the mixing mechanism 8 that extends out of the hopper 6. The power mechanism 704 drives the first end face tooth 705 to rotate. The first end face tooth 705 is equipped with a fork assembly that drives its sliding. By driving the first end face tooth 705 to rotate through the power mechanism 704, when the first end face tooth 705 engages with the second end face tooth 706, power is transmitted to the mixing mechanism 8 to make it rotate. The fork assembly can control the sliding of the first end face tooth 705, realizing the engagement or disengagement of the first end face tooth 705 and the second end face tooth 706, making it convenient for the user to remove the hopper 6 and the mixing mechanism 8, thereby cleaning the hopper 6 or replacing the biomass filler.

[0040] Furthermore, the shift fork assembly includes a fixed base 701, which provides mounting support for components such as the power mechanism 704, ensuring stable installation and normal operation of each component. Specifically, the fixed base 701 is fixedly connected to the toilet base 2, the power mechanism 704 is fixedly mounted on the fixed base 701, and a drive wheel 703 is fixedly connected to the output end of the power mechanism 704. A drive shaft is rotatably connected to the fixed base 701, and a driven wheel 702 is mounted on the drive shaft, which is driven by the drive wheel 703. In this embodiment, the drive wheel 703 and the driven wheel 702 are preferably meshing gears, and the driven wheel 702 has more teeth than the drive wheel 703, which can further reduce speed. The drive wheel 703 and the driven wheel 702 form a transmission system, or transmit the power of the power mechanism 704 to the drive shaft. The first end face tooth 705 is mounted on the drive shaft and can slide along the axial direction of the drive shaft. The mating part between the drive shaft and the first end face tooth 705 can be any of a square prism, hexagonal prism, or non-circular structure. The inner hole shape of the first end face tooth 705 matches the aforementioned mating part to prevent relative rotation between the first end face tooth 705 and the drive shaft. An elastic component 707, which is a spring, is provided between the first end face tooth 705 and the fixed base 701. The first end face tooth 705 is provided with a fork 708, the middle of which is rotatably connected to the fixed base 701. A connecting component 709 is provided at the end of the fork 708 away from the first end face tooth 705, and the other end of the connecting component 709 extends out of the toilet base 2. The connecting component 709 can be a flexible pull rope or a rigid pull rod. In use, the first end face tooth 705 can slide along the axial direction of the drive shaft and is kept in a normal state by the elastic component 707. The first end face tooth 705 and the second end face tooth 706 are engaged. When the hopper needs to be removed, the user pulls the connecting component 709, which drives the shift fork 708 to rotate. The shift fork 708 pushes the end face tooth 705 to slide, separating it from the end face tooth 706, thereby disconnecting the power transmission and making it easier to remove the hopper.

[0041] This embodiment does not limit the pulling position of the connecting component 709. When the connecting component 709 is a flexible pull cord, one or more reversing components 710 for reversing the connecting component 709 are installed on the toilet base 2. The reversing component 710 can be any of a fixed pulley, roller, or slip ring, as long as it can realize the reversing of the connecting component 709. The reversing component 710 can change the direction of the pulling force of the connecting component 709, allowing the user to arrange the connecting component 709 in any suitable position according to actual needs, which is convenient for user operation and improves the convenience and comfort of operation.

[0042] The toilet base 2 has an inspection port on the side near the power mechanism 704, and a rear cover plate 202 is fixedly connected to the inspection port. The inspection port and rear cover plate 202 facilitate the user's inspection and maintenance of internal components such as the drive device 7. When a component malfunctions, the rear cover plate 202 can be opened for inspection and repair. The toilet base 2 is equipped with a fan 9. The air inlet of the fan 9 is connected to the hopper 6, and the air outlet of the fan 9 extends out of this utility model, and the air outlet direction is not limited. The fan 9 draws air out of the hopper 6 through the air inlet and then discharges it through the air outlet, forming air circulation, accelerating the drying process of excrement in the hopper 6, reducing odor generation, and reducing the possibility of bacterial growth, thus keeping the air inside the toilet fresh and hygienic.

[0043] Working principle:

[0044] When a user uses the campervan toilet, excrement first enters the toilet bowl 5. Liquid excrement flows directly into the collection hopper 502. Since the outlet 501 on the collection hopper 502 is connected to the storage tank 3, the liquid excrement flows smoothly into the storage tank 3 for storage under the influence of gravity. Solid excrement falls into the sump 503, and then slides down through the sump channel 504 on the sump 503 under the influence of gravity into the hopper 6 inside the toilet base 2. The hopper 6 is filled with biomass filler and fermentation bacteria.

[0045] When the toilet is not in use, the toilet lid 1 can be closed to cover the inside of the toilet and reduce odor emissions. The baffle on the toilet bowl 5 can cover the defecation passage 504, further blocking odors and preventing debris from falling into the defecation passage 504 and causing blockages. When it is necessary to process the solid excrement in the hopper 6, the power mechanism 704 is activated. The drive wheel 703 at its output end rotates, which drives the transmission shaft and end face gear 705 to rotate through the driven wheel 702. This causes the stirring mechanism 8, which is fixedly connected to the end face gear 706, to start rotating in the hopper 6, stirring the solid excrement and biomass filler to prevent the excrement from accumulating and clumping, and also to prepare for subsequent composting. After processing is completed, the power mechanism 704 is turned off. During this process, the fan 9 on the toilet base 2 works continuously. Its air inlet is connected to the hopper 6, which draws out the air in the hopper 6 and discharges it to the outside of the toilet base 2 through the air outlet. This speeds up the drying of the excrement in the hopper 6, reduces odor, lowers the risk of bacterial growth, and keeps the air inside the toilet fresh and hygienic.

[0046] When the liquid tank 3 is full of liquid waste, the user can pull the liquid tank 3 out from the bottom of the toilet base 2, remove it, and drain the liquid waste in the liquid tank 3. After cleaning, the liquid tank 3 can be reinstalled into the toilet base 2 so that the toilet can continue to be used normally.

[0047] When the hopper 6 needs cleaning, tighten the connecting component 709. The elastic component 707 compresses, causing end face tooth 1 705 and end face tooth 2 706 to separate. Flip the toilet seat 4 upwards to remove the hopper 6 from the toilet base 2. After cleaning the solid waste from the hopper 6, reinstall the hopper 6 back into the toilet base 2 so the toilet can continue to function normally. Loosen the connecting component 709; under the reset action of the elastic component 707, end face tooth 1 705 and end face tooth 2 706 engage.

[0048] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
