Description

Technical Field

[0001] This utility model belongs to the field of toilet technology, and in particular relates to a fecal-urine separation system. Background Technology

[0002] Environmentally friendly toilets include waterless microbial degradation toilets. Waterless microbial degradation toilets require the separation of feces and urine at the source. Feces enter the feces treatment system, and urine enters the urine treatment system. Through different treatment methods, organic fertilizer is obtained. Therefore, the feces and urine separation system is an indispensable part of waterless microbial degradation toilets.

[0003] First, due to its waterless flushing nature, squat toilet panels and urine / feces separation systems typically employ enlarged inlets to ensure precise urine / feces flow. However, these enlarged inlets can easily cause odors to backflow into the toilet chamber. Therefore, in practical use, the urine / feces separation system and urine pipes are designed with negative pressure ventilation to prevent odor backflow. The design of multiple pipes and fans makes installation and maintenance in a space-constrained equipment layer a significant challenge, increasing operating costs. Second, due to the stickiness of feces, it is easy for feces to remain on the urine / feces separation system. Therefore, in practical use, the urine / feces separation system is designed with automatic cleaning to periodically remove residual feces, keep the system clean, and prevent blockages and odors. However, even automatic cleaning devices carry the risk of feces sticking to the system. Furthermore, regarding the urine collection section, the enlarged urine / feces inlets pose a risk of objects falling in, which can clog the urine pipes due to gravity.

[0004] To improve the reliability of the fecal-urine separation system and further ensure the overall usability and environmental performance of the waterless microbial degradation toilet, these existing problems need to be solved. Utility Model Content

Detailed Implementation

[0083] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0084] like Figures 1-7 As shown in the figure, this embodiment discloses a fecal-urine separation system, including: a housing, a fecal-urine separation component, a cleaning component, and an exhaust component.

[0085] The top of the housing is provided with a fecal and urine inlet 1011; the fecal and urine separation component is located below the fecal and urine inlet 1011 to receive and separate fecal and urine; the exhaust component is provided on one side of the housing; wherein, the fecal and urine separation component includes: a movable scraper assembly, an inclined receiving base plate 3, a urine tank 4 and a urine pipe 103.

[0086] The movable scraper assembly, the inclined receiving base plate 3, and the urine tank 4 are all located below the fecal and urine inlet 1011 by being connected to the side wall of the housing; the movable scraper assembly can clean the feces on the inner wall of the housing and the inclined receiving base plate 3.

[0087] In this embodiment, the urine tank 4 is located below the lower end of the inclined receiving base plate 3; the gap between the higher end of the inclined receiving base plate 3 and the inner wall of the housing forms a fecal fallout port. One end of the fecal-urine separation assembly is equipped with the cleaning component, which can be used to clean the scraper of the movable scraper assembly; the exhaust assembly includes an exhaust port and an air duct 102 disposed on the housing. The air duct 102 is connected to the exhaust port, the urine pipe 103, and the negative pressure exhaust gas treatment device via an air duct tee connector 1021; the urine pipe 103 is connected to the exhaust port, the urine tank 4, and the urine treatment device via a urine pipe tee connector 1031. In actual use, this design effectively reduces odor, makes installation more convenient, and reduces costs.

[0088] The movable scraper assembly described in this embodiment includes: a first scraper 202, a first scraper bracket 201, a first scraper pressure plate 203, a first power mechanism 206, and a connecting component connecting the first scraper 202 and the first power mechanism 206.

[0089] The first scraper 202 has an interference fit with the inner wall of the housing on both sides, with an interference amount of 0.5mm; the lower side of the first scraper 202 has an interference fit with the inclined receiving base plate 3, with an interference amount of 1.5mm and a tolerance of ±0.2mm; the interference amount in this embodiment has been verified multiple times to confirm the optimal value.

[0090] The first power mechanism 206 can drive the first scraper 202 to move laterally and reciprocally to clean the feces on the inner wall of the housing and the inclined receiving base plate 3; the first scraper 203 is made of TPU material. This material scrapes cleanly, has little wear, and is highly durable in practical applications.

[0091] In this embodiment, the first scraper 202 is pressed and mounted on the first scraper bracket 201 by means of the first scraper pressure plate 203. The first scraper bracket 201 is U-shaped; the left and right sides of the first scraper bracket 201 are respectively tightly connected to the upper parts of the two linear sliders 204. The two linear sliders 204 are respectively connected to the two linear slide rails 205 through slots; the two linear slide rails 205 are arranged on the left and right sides of the outside of the housing; one side of the linear slide rail 205 on the housing is connected to a rack; the rack meshes with a gear for transmission; the first power mechanism 206 is a motor; the motor controls the rotation of the gear.

[0092] In this embodiment, the housings at both ends of the linear slide rail 205 are respectively provided with strip-shaped holes 104; a proximity switch is provided in the strip-shaped hole 104; the proximity switch can sense the moving position of the first scraper bracket 201; the proximity switch can move within the strip-shaped hole 104 to achieve dynamic and precise adjustment of the operating range of the first scraper bracket 201.

[0093] In this embodiment, the inclined receiving base plate 3 is used to receive feces and urine, and is fixedly connected to the housing, with an inclination angle of 1-5°. The movable scraper assembly maintains the same inclination angle as the inclined receiving base plate 3; the urine tank 4 is inclined, with an inclination angle of 1-5°. The higher side of the inclined receiving base plate 3 is 10-15cm away from the inner wall of the housing; the feces drop outlet corresponds to the feces treatment device below.

[0094] In this embodiment, the higher side of the inclined receiving base plate 3 is a rounded, inwardly folded corner structure; when the first scraper 202 moves to clean, the feces on the inclined receiving base plate 3 slides over the rounded, inwardly folded corner structure and falls into the feces drop outlet.

[0095] It should be noted that non-circular shapes can easily cause wear to the first scraper 202. If an inward-curving design is not used, the feces cannot be guaranteed to fall off completely and there is still a possibility that they will stick to the inclined receiving base plate 3.

[0096] The cleaning assembly described in this embodiment includes: a second scraper 603, a second scraper bracket 601, a second scraper pressure plate 602, a second power mechanism 604, and a drive connection assembly connecting the second scraper 603 and the second power mechanism 604.

[0097] Specifically, the second power mechanism 604 is a drive motor; the drive connection assembly includes a coupling and a rotating shaft. The housing has a shaft hole; the rotating shaft is mounted inside the housing via the shaft hole and bearings; one end of the coupling is connected to the drive motor, and the other end is connected to the rotating shaft. A second scraper bracket 601 is fixedly mounted on the rotating shaft; a second scraper 603 is mounted on the second scraper bracket 601 and pressed against it by a second scraper pressure plate 602. The drive motor is fixedly mounted on a motor mounting bracket outside the housing and rotates within the housing via the rotating shaft and mounting plate to clean the first scraper 202.

[0098] The second scraper 603 is interference-fitted with the first scraper 202; the first contact edge of the second scraper 603 contacting the first scraper 202 is 3mm to 5mm away from the upper edge of the first scraper bracket 201. The contact point is a certain distance from the upper edge, so that the feces are not easily scraped onto the first scraper bracket 201, and the cleaning range of the first scraper 202 is maximized.

[0099] In this embodiment, a beveled fixing bracket 8 is provided inside the housing within the rotation radius of the second scraper 603 for cleaning the second scraper 603. A single strip bracket cannot guarantee a smooth weld and is prone to deformation. The beveled design ensures a smooth weld and is not easily deformed. A fixing scraper 5 is also provided inside the housing; the fixing scraper 5 is positioned above the first scraper bracket 201 and is used to clean the first scraper bracket 201 when the first scraper bracket 201 moves.

[0100] In this embodiment, the top of the shell is a cover plate 101; the cover plate 101 is provided with a feces and urine inlet 1011; the cover plate 101 is provided with an integrally formed enclosure around the feces and urine inlet 1011; the enclosure is used to connect the feces and urine inlet of the toilet.

[0101] In this embodiment, a control component is also provided outside the housing; the control component is connected to the first power mechanism 206 and the second power mechanism 604 respectively, and can control the operation of the first power mechanism 206 and the second power mechanism 604 respectively; the control component includes: a human body sensor, a switch connected to the first power mechanism 206 and the second power mechanism 604, a controller that receives the human body sensor signal and is connected to the switch, and a power supply.

[0102] Example 2

[0103] like Figures 1-7 As shown: This embodiment discloses as follows Figure 1 As shown, a fecal-urine separation system includes: a housing, a fecal-urine separation component, a cleaning component, and an exhaust component;

[0104] In this embodiment, the shell is a hollow structure that runs through the top and bottom, with a cover plate 101. From top to bottom, a fecal and urine inlet 1011 and a fecal and urine separation component are arranged sequentially. A cleaning component is provided at one end of the fecal and urine separation component, and an exhaust component is provided on one side of the shell.

[0105] In this embodiment, the feces and urine separation component includes a movable scraper assembly, an inclined receiving base plate 3, a urine tank 4, a feces drop outlet, and a urine tube 103. The movable scraper assembly includes a first scraper 202, a first scraper bracket 201, a first scraper pressure plate 203, a first power mechanism 206, and a connecting component connecting the first scraper 202 and the first power mechanism 206. The left and right sides of the first scraper 202 are interference-fitted with the inner wall of the housing with an interference amount of 0.5mm, and the lower side is interference-fitted with the inclined receiving base plate 3 with an interference amount of 1.5mm, with a tolerance of ±0.2mm. The first power mechanism 206 drives the first scraper 202 to move laterally back and forth to clean the inner wall of the housing and the inclined receiving base plate 3.

[0106] In this embodiment, a first scraper 202 is pressed onto the first scraper bracket 201 by means of a first scraper pressure plate 203; the first scraper bracket 201 is U-shaped groove, and the left and right sides of the first scraper bracket 201 are respectively tightly connected to the top of two linear sliders 204; the two linear sliders 204 are respectively connected to two linear slide rails 205 through slots; the two linear slide rails 205 are arranged on the left and right sides of the outer shell; the linear slide rails 205 on the left and right sides of the shell are connected to a rack, and the rack meshes with a gear for transmission; the first power mechanism 206 is a motor, and the motor controls the rotation of the gear.

[0107] In this embodiment, the first scraper 202 is made of TPU material.

[0108] In this embodiment, the operating range of the first scraper 202 is controlled by proximity switches at both ends. A strip-shaped hole 104 is provided on the housing of the proximity switches. This is to allow for proper adjustment of the position of the first scraper bracket 201 at the end of the urinal 4, ensuring that the gap between the first scraper 202 and the inclined receiving base plate 3 allows urine to flow smoothly into the urinal 4, while preventing large items such as lighters from entering the urinal tube 103 and causing blockage. (The original design used a circular hole, which prevented movement of the proximity switches and fixed the scraper's position. Due to uneven ground conditions during installation, the gap between the scraper and the inclined plate became too large or too small, causing blockages in the urinal tube.)

[0109] The inclined receiving base plate 3 is used to receive feces and urine, and is fixedly connected to the shell. The inclination angle is 1-5°, preferably 3°. The movable scraper assembly maintains the same inclination angle. A urine trough 4 is provided below the lower side of the inclined receiving base plate 3. The urine trough 4 is fixedly connected to the shell and is inclined at an angle of 1-5°, preferably 1°. A urine outlet and a connected urine pipe 103 are provided on the lower side of the shell connected to the urine trough 4. The urine outlet is connected to a urine treatment device. The feces drop outlet is located 10-15cm away from the inner wall of the shell on the higher side of the inclined receiving base plate 3, and the feces drop outlet corresponds to the feces treatment device.

[0110] Furthermore, the higher side of the inclined receiving base plate 3 is provided with an arc-shaped inward-curving angle. When the first scraper 202 moves to the right (distinguished by left and right in the front view), the feces on the right side of the first scraper 202 are cleaned by the design of the arc-shaped inward-curving angle.

[0111] In this embodiment, the cleaning assembly includes a second scraper 603, a second scraper bracket 601, a second scraper pressure plate 602, a second power mechanism 604, and a connecting assembly connecting the second scraper 603 and the second power mechanism 604. The second power mechanism 604 is a motor, and a shaft hole is provided on the housing. The rotating shaft is installed in the housing by means of the shaft hole and bearings. One end of the coupling is connected to the motor, and the other end is connected to the rotating shaft. The second scraper bracket 601 is fixedly mounted on the rotating shaft. The second scraper 603 is mounted on the second scraper bracket 601 and is pressed against the second scraper bracket 601 by means of the second scraper pressure plate 602. The motor is fixedly mounted on a motor mounting bracket on the outside of the housing, and drives the second scraper 603 to rotate in the housing by means of the rotating shaft and the mounting plate, so as to clean the first scraper 202. By using a proximity switch and a strip hole 104, an interference fit between the second scraper 603 and the first scraper 202 can be ensured. The distance between the first contact edge of the second scraper 603 and the first scraper 202 and the upper edge of the first scraper bracket 201 is set to 3mm to 5mm.

[0112] Furthermore, an angled fixing bracket 8 is provided within the rotation radius of the second scraper 603 to clean the second scraper 603 when it rotates.

[0113] When the second scraper 603 rotates, the residual feces on the second scraper 603 may be scraped onto the first scraper support 601. A scraper is fixedly installed in front of the feces outlet by a fixed scraper pressure plate and a fixed scraper support. If the feces remain on the first scraper support 201, the first scraper support 201 will be cleaned when it moves to the right. The cleaned feces will fall onto the inclined receiving base plate 3 due to gravity, waiting for the first scraper 202 to clean it again, and finally fall into the feces treatment device from the feces drop outlet.

[0114] In this embodiment, the ventilation assembly includes a ventilation port on the housing and a connecting duct 102. The duct 102 connects to a fan and an exhaust gas treatment device. The duct 102 on the housing is connected to the urine tube 103 by a flexible hose. In the past, the equipment did not use a T-junction, and the urine tube 103 needed to be vented under negative pressure separately. Now, a duct T-junction interface is provided, and the negative pressure of the duct 102 is directly connected to the urine tube 103 to provide negative pressure to the urine tube 103, reducing the number of fans used and reducing the layout of pipelines.

[0115] In this embodiment, a cover plate 101 is also provided on the housing; the cover plate 101 is provided with a fecal and urine inlet 1011; the cover plate 101 is provided with an integrally formed enclosure around the fecal and urine inlet; the enclosure is used to connect the fecal and urine inlet of the toilet.

[0116] In this embodiment, a base plate assembly 7 is also included, which is used to fit onto the housing. The housing is installed on the fecal processor by means of the base plate assembly 7. An installation bracket is also provided on the periphery of the lower part of the housing for movably connecting with the base plate assembly, so as to adjust the overall height of the device on the fecal processor and better match the toilet and the fecal treatment device.

[0117] Specifically, the mounting bracket below the housing is connected to the base plate assembly 7 via the screw and fixed with a nut; the screw adjusts the overall height of the device on the fecal processor via the nut.

[0118] In this embodiment, the outer casing should also be provided with a control component connected to the first power mechanism 206 and the second power mechanism 604, for controlling the controlled operation of the first power mechanism 206 and the second power mechanism 604; the control component includes: a human body sensor, a switch connected to the first power mechanism 206 and the second power mechanism 604, a controller that receives the human body sensor signal and is connected to the switch, and a power supply.

[0119] In this embodiment, when a user uses the toilet, the human body sensor sends a signal, and the control component controls the motor to open the first scraper bracket. Feces and urine enter the housing and fall onto the inclined receiving base plate 3. Due to the inclined setting of the inclined receiving base plate 3, urine automatically flows to the lower side of the inclined receiving base plate 3 and enters the urinal, and enters the urine treatment device through the urination port; feces remain on the receiving surface.

[0120] After the user finishes using the toilet, the control component controls the motor to run, closes the first scraper bracket 201, and the first scraper 202 scrapes the feces from the higher end into the feces drop outlet into the feces processor.

[0121] When the first scraper bracket 201 is paused, the control component controls the motor of the second scraper 603 to run, and the second scraper 603 rotates to clean the first scraper 202. Through the above operation, the inner wall of the housing, the first scraper 202, and the supporting floor are cleaned. Finally, the control component controls the fan of the exhaust vent to exhaust air and prevent odors from rising, so that there is no odor in the toilet room.

[0122] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of this utility model without creative effort, and these embodiments will all fall within the scope of protection of this utility model.
