Description

Technical Field

[0001] This invention relates to the field of ecological sanitation equipment technology, specifically to an ecological toilet for locomotives. Background Technology

[0002] Currently, due to various objective reasons, locomotives of various models, including the Harmony locomotive, suffer from varying degrees of toilet malfunction, which seriously affects the normal work and life of locomotive drivers and passengers. In reality, locomotive toilets are cramped, poorly ventilated, and generally suffer from poor toilet experience, strong residual odors, and difficulty in cleaning up dirt, which can easily breed harmful bacteria and pose a significant potential hazard to the health and hygiene of users.

[0003] Chinese patent CN200910008633.6 discloses an ecological toilet suitable for locomotive or ship drivers, including a main unit and a toilet bowl, with the toilet bowl located above the main unit. The main unit includes a fermentation tank and a motor chamber. A stirrer connected to a motor via a mechanical transmission device is installed in the fermentation tank, which contains microbial agents. After use, excrement is flushed into the fermentation tank, where it is then stirred to aid in decomposition. However, the separate design of the fermentation tank and toilet bowl results in a large space requirement, making it unsuitable for the confined space of locomotive toilets. Furthermore, the horizontal placement of the stirrer within the fermentation tank significantly increases the space required. The direct storage of microbial agents within the fermentation tank can easily contaminate the microbial community after a period of time, causing it to lose its activity. Additionally, the heating device is located at the bottom outside the fermentation tank, resulting in high energy consumption during heating and inconvenience in use.

[0004] In addition, the bottom-mounted design of the fermentation tank makes it difficult to clean after a period of use, causing great difficulties in cleaning. Furthermore, the fermentation tank lacks an exhaust system, so harmful gases or odors produced inside the tank cannot be effectively removed after prolonged use, seriously affecting the user's toilet experience and health. Considering the usage environment of locomotive toilets, the installation of this device is also quite troublesome.

[0005] Based on this, the inventors designed a brand-new ecological toilet. The appearance of this toilet is not much different from that of common toilets on the market. The stirring device is set in the treatment chamber, which effectively reduces the space occupied by the device. At the same time, the microbial liquid of this toilet is stored in the storage box. When in use, it is sprayed into the treatment chamber under the action of the power unit. This facilitates the storage of microbial liquid. At the same time, the design of the storage box being located inside the base also effectively saves the arrangement space, making this device very suitable for placement in small environments such as locomotive toilets. Summary of the Invention

[0006] To address the problems of poor air circulation, strong residual odors, difficulty in cleaning up dirt, and easy growth of harmful bacteria in locomotive toilets due to their small size, which pose significant potential health hazards to users, and the difficulty in placing toilets in such confined spaces, this invention provides an eco-friendly locomotive toilet suitable for use in locomotive toilets and other confined spaces.

[0007] The technical solution of this invention is as follows:

[0008] A locomotive eco-friendly toilet includes a toilet body and a lid-closing system. The toilet body includes a base and a treatment compartment. The base is vertically arranged, hollow inside, and has a vertically arranged treatment compartment. The lid-closing system is located on the upper part of the base and above the treatment compartment, so that the treatment compartment can cover the upper opening when it is performing treatment work to prevent odors from escaping.

[0009] Furthermore, the base is equipped with a bacterial solution addition system, which includes a storage tank and a power unit. The storage tank contains microbial solution, which can be added to the treatment chamber under the action of the power unit. Through the degradation of excrement by the microbial solution, the biodegradable organic matter in the user's excrement can be completely decomposed into simple inorganic matter, realizing the harmless and resource-based treatment of feces, basically achieving zero emissions and not causing environmental pollution. When adding bacterial solution, the amount added at one time is 3-15mL. When the amount added is too small, it is easy to fail to completely decompose the excrement or the decomposition time is too long. When the amount added is too large, it shortens the replacement cycle of bacterial solution and the cleaning cycle of treatment chamber.

[0010] Furthermore, the treatment chamber is a hollow structure with an opening at the top, and the opening at the top is flush with the upper part of the base to receive excrement. The lower end of the treatment chamber is equipped with a stirring and mixing system. Through the stirring action of the stirring and mixing system, the microbial liquid and excrement can be mixed evenly, reducing the required amount of microbial liquid to be added, effectively shortening the degradation time, and greatly improving the degradation efficiency.

[0011] As described above, the locomotive eco-friendly toilet includes a treatment chamber and a second connecting plate. The treatment chamber has an opening at its upper end, through which it can receive excrement. The interior of the chamber is used for the decomposition of excrement. The second connecting plate is located outside the opening at the upper end of the treatment chamber. The treatment chamber is detachably connected to the upper end of the base through the second connecting plate, allowing the treatment chamber to be disassembled for cleaning after a long period of use, reducing the difficulty of cleaning and increasing the practicality of the device.

[0012] Furthermore, an exhaust purification system is provided on the upper side of the processing chamber of the processing compartment and below the second connecting plate. The exhaust purification system is connected to the outside through a connecting device, so that the odor generated during use or decomposition can be effectively discharged, improving the toilet experience. A gravity sensing system is provided on the upper outer ring of the second connecting plate, so that the stirring and mixing device can operate according to the signal transmitted by the gravity sensing system, and the excrement decomposition work is carried out when no one is using it.

[0013] Furthermore, the base is equipped with a heating and insulation system circumferentially located near the processing chamber. This system controls the temperature to enhance the activity of the microbial community in the microbial liquid, reducing the decomposition time. At the same time, the decomposition process also evaporates the generated water, which is then discharged through the exhaust purification system, increasing the service life of the device and reducing the replacement and cleaning cycle.

[0014] As described above, in a locomotive eco-friendly toilet, the bacterial liquid addition system includes a nozzle connected to the middle of the lid-closing system. When the lid-closing system is closed, the nozzle is located above the opening of the treatment chamber. The bacterial liquid is added by spraying, which makes the bacterial liquid and excrement mix more evenly and fully, effectively reducing the decomposition time.

[0015] As described above, the locomotive ecological toilet includes a mixing system comprising a mixing motor and mixing blades. The mixing motor is vertically positioned in the middle of the lower end of the treatment chamber, with its upper end serving as a transmission end. The transmission end is connected to the mixing blades, which position the mixing blades in the middle of the lower end of the treatment chamber. This allows for a more uniform mixing of the bacterial solution and the excrement during the auxiliary excrement decomposition and mixing process.

[0016] Furthermore, the stirring blade includes a connecting shaft and a fan blade assembly. The stirring blade is connected to the drive end of the stirring motor via the connecting shaft. The fan blade assembly is arranged circumferentially, and the fan blade assembly has one or more blades, which include several fan blades arranged circumferentially around the connecting shaft. Compared with stirring cages, stirring rods or other stirring methods, its stirring effect is more obvious. At the same time, the fan blade stirring occupies less space and is more convenient to arrange.

[0017] Preferably, when there are multiple fan blade groups, the multiple fan blade groups have different heights, and the rotation diameter of the upper fan blade group is larger than that of the lower fan blade group. Combined with the constricted design at the lower end of the processing chamber, the multiple fan blade groups work in layers during the stirring operation, and the stirring work of each layer of fan blades can be fully completed.

[0018] As described above, in a motorcycle-style eco-friendly toilet, a height step is provided at the lower front end of the base along the outer circumference of the base, providing standing space for the user and improving user comfort.

[0019] As described above, the locomotive eco-friendly toilet includes a lid-closing system comprising a top cover, an automatic cover-changing system, and a detection device. The automatic cover-changing system is located at the top of the base, and the top cover is rotatably connected to the upper part of the automatic cover-changing system. Rotation controls the opening and closing of the processing chamber. The automatic cover-changing system can complete the automatic cover-changing operation based on the signal transmitted by the detection device, improving hygiene and protecting the user's health.

[0020] The beneficial effects of this invention are as follows:

[0021] The treatment chamber, combined with a stirring device and a bacterial liquid addition system, can completely decompose the biodegradable organic matter in the user's excrement into simple inorganic matter, achieving harmless and resource-based treatment of feces, basically achieving zero emissions and not causing environmental pollution.

[0022] The design of the processing compartment being located inside the base reduces the space required for device placement, making the device suitable for use in confined spaces such as locomotive toilets.

[0023] The exhaust purification system, combined with the lid closing system, ensures that odors and other gases produced during decomposition after use can be effectively expelled to the outside, guaranteeing a good toilet experience and the health of the user. At the same time, the water produced during decomposition is also evaporated by the heating and insulation system and discharged to the outside, increasing the replacement cycle of the treatment chamber.

[0024] The detachable connection between the treatment chamber and the base makes cleaning the device more convenient.

[0025] The addition of microbial liquid by spraying, combined with the stirring of the mixing device, ensures that the excrement is evenly mixed with the liquid, reducing the decomposition time. At the same time, the method of adding the liquid by spraying is more conducive to the preservation and replacement of the liquid. Attached Figure Description

[0043] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. It should be noted that these embodiments are provided to enable a more thorough understanding of this disclosure and to fully convey the scope of this disclosure to those skilled in the art. This disclosure can be implemented in various forms and should not be limited to the embodiments set forth herein. Example

[0044] This embodiment provides an eco-friendly toilet for locomotives; see [link / reference]. Figures 1-3 The toilet includes a toilet body and a lid-closing system 3. The toilet body includes a base 1, a treatment chamber 2, and a height-adjustable pedal. The base 1 is vertically arranged, hollow inside, and has the treatment chamber 2 vertically positioned. The lid-closing system 3 is located on the upper part of the base 1 and above the treatment chamber 2, so that the treatment chamber can cover the upper opening during treatment to prevent odors from escaping. The height-adjustable pedal is located at the lower front end of the base 1 and is set along the outer ring of the base 1, providing standing space for the user and improving user comfort.

[0045] In this embodiment, combined with Figures 4-6 The base 1 includes a support shell and a first connecting plate 13. The support shell is the main shell of the toilet, which is hollow inside and plays a major supporting role. The first connecting plate 13 is horizontally located on the upper part of the support shell and is used to connect the treatment chamber 2 and the lid closing system 3.

[0046] Furthermore, the support shell includes a front support shell 11, a rear support shell 12, and a chassis. One end of the chassis is an outwardly protruding arc-shaped structure, and the other end is square, and it is horizontally located below the base 1. The rear support shell 12 is a cuboid structure, which is vertically located at one end of the square end of the chassis and matches the square end of the chassis. The thickness of the rear support shell 12 is less than the length of the square end of the chassis. The front end of the front support shell 11 is a vertical semi-cylindrical structure, and both sides extend to the rear end and connect with the rear support shell 12. The diameter of the semi-cylindrical structure is smaller than the diameter of the arc segment of the chassis, and the lower part of the front support shell 11 is tapered inward.

[0047] Furthermore, the first connecting plate 13 has the same structure as the chassis and is located at the upper end of the support shell. It has an installation port 131 at the middle of one end near the front support shell 11. The installation port 131 is a circular structure and is located at the middle of the arc-shaped end of the front support shell 11.

[0048] Furthermore, a heating plate 15 is provided circumferentially around the lower part of the mounting port 131 along its axis. The heating plate 15 is cylindrical in shape, and a phase change material filler 14 is provided circumferentially inside the lower end of the heating plate 15. The outer ring of the phase change material filler 14 matches the inner ring of the heating plate 15, and the middle part of the heating plate 15 has an upward-opening bowl-shaped notch at the bottom inside the heating plate 15. The heating plate 15 is made of graphene. When heating is required, the graphene heating material is energized and heated, and the heat is transferred to the phase change material filler 14. When heating is stopped, the heating plate 15 is powered off, the graphene heating material stops heating, and the phase change material filler 14 slowly releases heat, achieving the effect of simultaneous heating and heat preservation, reducing the energy consumption required for heat dissipation, and ensuring the activity of microbial communities.

[0049] Furthermore, the heating plate 15 has a notch at the upper end near the rear support shell 12, and the first connecting plate 13 is provided with an exhaust purification system 16 at the lower part and outside the notch. The exhaust purification system 16 includes an axial flow fan, which connects the processing chamber 2 to the outside, so that the odor generated during use or decomposition can be effectively discharged, improving the toilet experience. At the same time, the water vapor generated by heating is also extracted by the exhaust purification system 16, which greatly extends the cleaning time of the processing chamber 2.

[0050] Furthermore, the base 1 also includes a spray system 17, which includes a liquid storage tank 171, a feeding pump 172, a suction pipe 173, a discharge pipe 174, and a nozzle 175. The liquid storage tank 171 and the feeding pump 172 are both located inside the bottom of the rear support shell 12, close to both the front and rear ends of the rear support shell 12. The liquid storage tank 171 contains microbial liquid; the specific composition is not limited in this invention, but can be referenced, for example, in CN200910008633.6. The microbial agent in the patent has a suction pipe 173 connecting a storage tank 171 and a feeding pump 172, and an outlet pipe 174 connecting the feeding pump 172 and a nozzle 175. The nozzle 175 is located at the lower middle part of the capping system 3 and above the treatment chamber 2. The microbial liquid in the storage tank 171 can be sprayed into the treatment chamber 2 under the action of the feeding pump 172. By degrading excrement with microbial liquid, the biodegradable organic matter in the excrement of workers can be completely decomposed into simple inorganic matter, realizing the harmless and resource-based treatment of feces, basically achieving zero emissions and not causing environmental pollution. When adding the microbial liquid, the amount added at one time is 8mL. When the amount added is too small, it is easy to fail to completely decompose the excrement or the decomposition time is too long. When the amount added is too large, on the one hand, the replacement cycle of the microbial liquid is shortened, and on the other hand, the cleaning cycle of the treatment chamber is shortened. At the same time, the method of adding the microbial liquid by spraying makes the mixture of microbial liquid and excrement more uniform and sufficient, effectively reducing the decomposition time.

[0051] In this embodiment, combined with Figures 8-10The treatment chamber 2 includes a chamber body 21 and a stirring and mixing device. The stirring and mixing system 22 is vertically arranged at the bottom of the chamber body 21. Through the stirring action of the stirring and mixing system 22, the microbial liquid and excrement can be mixed evenly, which reduces the requirement for the amount of microbial liquid to be added, effectively shortens the degradation time, and greatly improves the degradation efficiency.

[0052] Furthermore, the cabin 21 includes a processing chamber 211 and a second connecting plate 212. The processing chamber 211 includes a first chamber 2111 and a second chamber 2112. The first chamber 2111 is a vertically arranged cylindrical structure. The second chamber 2112 is located at the bottom of the first chamber 2111 and is in the shape of a funnel that tapers downwards in an arc. A through hole is provided in the middle of the bottom end of the second chamber 2112. The front end of the second connecting plate 212 is arc-shaped and has the same shape as the arc-shaped structure at the front end of the first connecting plate 13. The rear end of the second connecting plate 212 is rectangular, and the length of the second connecting plate 212 is less than the length of the first connecting plate 13. A circular opening is provided in the middle of the front end of the second connecting plate 212. The upper end of the first chamber 2111 is connected to the lower part of the circular opening through a connecting device, and the axis coincides with the axis of the circular opening.

[0053] Furthermore, the lower part of the second connecting plate 212 and the inner circumferential side of the first chamber 2111 are provided with six blue LED light sources, and the lower front part of the second connecting plate 212 is also provided with a gravity sensor, and the lower rear part is provided with an electrical connector 2121. The gravity sensor and the blue LED light sources are connected to the power supply through the electrical connector 2121. The processing chamber 211 is inserted downward from the mounting port 131 of the first connecting plate 13, and the processing chamber 2 and the base 1 are detachably connected by the cooperation of the first connecting plate 13 and the second connecting plate 212. This allows the processing chamber 2 to be disassembled for cleaning after a long period of use, reducing the difficulty of cleaning and increasing the practicality of the device. The second chamber 2112 cooperates with the bowl-shaped opening of the phase change material filler 14 and fits closely to the phase change material filler 14.

[0054] Furthermore, the mixing system 22 includes a stirring motor 221 and stirring blades 222. The stirring motor 221 is vertically arranged inside the bottom through hole of the second chamber 2112 and is sealed to the bottom through hole of the second chamber 2112. Its transmission end is located inside the second chamber 2112 and is connected to the stirring blades 222. The stirring blades 222 include a connecting shaft and a fan blade assembly. The stirring blades 222 are connected to the transmission end of the stirring motor 221 through the connecting shaft. The fan blade assembly includes three fan blades that are evenly arranged circumferentially around the connecting shaft. There are two fan blade assemblies, one of which is located at the connecting shaft. At the upper end of the shaft, another is located at the lower end of the connecting shaft, and the rotation diameter of the upper fan blade group is larger than that of the lower fan blade group. Combined with the constricted design at the lower end of the processing chamber, multiple fan blades work in layers during the stirring operation, and the stirring work of each layer of fan blades can be fully completed. Furthermore, a vent is provided at the upper end of the first chamber 2111 near the notch of the heating plate 15. The vent is connected to the exhaust purification system 16 through a connecting device. The stirring and mixing device and the exhaust purification system 16 can operate according to the signal transmitted by the gravity sensor, and the excrement decomposition work is carried out when no one is using it.

The automatic cover changing system 32 is located at the upper end of the base 1. The upper cover 31 is rotatably connected to the upper part of the automatic cover changing system 32, and the opening and closing of the processing chamber 211 can be controlled by rotation. The automatic cover changing system 32 can complete the automatic cover changing work according to the signal transmitted by the detection device, which improves the hygiene of use and protects the health of users.

[0056] In this embodiment, the automatic toilet seat cover changing system 32 includes a seat cushion 321 and a cover changing device 322. The cover changing device 322 includes a third connecting plate 3221. The cover changing device 322 is connected to the upper rear end of the first connecting plate 13 through the third connecting plate 3221. The seat cushion 321 is U-shaped and horizontally arranged, with one end rotatably connected to one side of the cover changing device 322. The cover changing device 322 also includes a first roller 3222 and a second roller 3223, which are located on both sides of the cover changing device 322, respectively. The first roller 3222 is closer to the end where the seat cushion 321 connects to the cover changing device 322, and the second roller 3223 is closer to the other end. The two rollers are horizontally arranged. The second roller 3223 is used to store new toilet seat covers. One end of the toilet seat cover passes through the seat cushion 321 and is then connected to the first roller 3222. The first roller 3222 is used to roll up the old toilet seat cover.

[0057] Furthermore, the upper cover 31 is rotatably connected to the upper part of the sleeve changing device 322 near the seat cushion 321. The opening and closing action of the processing chamber 2 is completed by rotation in the vertical plane. The nozzle 175 is located below the middle of the upper cover 31. The sleeve changing device 322 is also provided with a counting device near the second roller 3223. The counting device is rotatably connected to the front end of the second roller 3223. When the toilet seat cover passes through the counting device, it can drive the counting device to rotate, and the remaining amount of toilet seat cover can be known by counting its rotation.

[0058] Furthermore, the sleeve changing device 322 is provided with a sensor switch at the front end of the middle section, and the automatic sleeve changing operation of the sleeve changing device 322 can be controlled by the sensor switch. At the same time, a cover closing motor is provided above the sensor switch, and the drive end of the cover closing motor is connected to the upper cover 31.
