Description

Technical Field

[0001] This utility model relates to the field of skateboards, and more particularly to a biodegradable toilet seat. Background Technology

[0002] Currently, many RVs are equipped with bio-toilets, such as the waterless eco-toilet with publication number CN109700364A and publication date of May 3, 2019. This type of toilet includes a sliding plate, a toilet bowl shell, a scraper, a fecal fermentation device, and a urine decomposition device. When urine falls onto the sliding plate from the toilet bowl opening, it flows quickly into the urine collection tank through the tilted sliding plate according to fluid dynamics and gravity. Defecation falls onto the sliding plate. After use, pressing a button or sensing the device causes the sliding plate to retract, and the feces, after being scraped by the scraper, fall into the fermentation tank for fermentation and decomposition. If the scraper does not completely remove the feces from the sliding plate, it will cause odor and affect the user's experience, requiring additional cleaning with a brush to remove any remaining feces. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a biodegradable toilet seat that prevents feces from falling onto the slide, allows urine on the slide to flow out completely, and reduces odor.

[0004] To achieve the above objectives, one of the technical solutions adopted by this utility model is: a biodegradable toilet seat, including a seat body, the seat body being located between the bio-reaction chamber of the bio-toilet and the toilet seat, the seat body being moved back and forth in the horizontal direction by a drive source to open or close the reaction chamber, the upper end face of the seat body being integrally formed with a guide groove, a guide channel being provided below the guide port of the guide groove, the guide channel being fixed on the base of the bio-toilet, and the guide channel being connected to a drain pipe.

[0005] The beneficial effects of this biodegradable toilet seat are that the seat body is driven by a drive source to open or close the bioreactor chamber. When urinating, the seat body prevents urine from entering the bioreactor chamber. When defecating, the seat body opens the bioreactor chamber, and excrement is directly discharged into the bioreactor chamber. The scraper structure is eliminated, the structure is simple, and the phenomenon of excrement sticking to the seat body is reduced. In addition, the seat body has a urine guide channel, which can guide the urine to flow through the guide channel and finally discharge it from the drain pipe, reducing the retention of urine on the seat body and minimizing odor residue.

[0006] Preferably, a baffle is integrally formed on the outer circumference of the cover plate body, the middle part of the cover plate body is raised upward, and the circumferential edge of the cover plate body is recessed downward to form the guide groove. By setting the baffle, splashing of urine on the cover plate body can be prevented, and the urine is ultimately blocked by the baffle and flows to the surrounding guide groove, which can better drain into the guide channel.

[0007] Preferably, the bottom of the guide channel on the side with the guide channel is lower than the bottom of the side opposite to the guide channel. This allows the urine in the guide channel to flow more effectively in the direction of the guide channel.

[0008] Preferably, the flow guide is a straight section of extended pipe, and the cross-section of the straight section of extended pipe is U-shaped.

[0009] Preferably, the guide channel has a guide cavity inside, and a slot is formed on the side wall of the guide channel. When the cover plate body moves back and forth horizontally, the straight section extension pipe can move back and forth in the direction of extending into the slot and away from the slot.

[0010] Preferably, the bottom of the guide channel is provided with a guide outlet pipe, and the lower end of the guide outlet pipe is connected to the top of the drain pipe.

[0011] Preferably, the guide channel further includes a buffer chamber, which is connected to the guide chamber. The bottom of the buffer chamber is higher than the bottom of the guide chamber, and the bottom of the buffer chamber is inclined towards the guide chamber. Because the outlet of the guide channel is small and the discharge speed is limited, the addition of the buffer chamber expands the urine storage space, preventing overflow caused by a large amount of urine flowing down rapidly and the guide channel being unable to discharge urine quickly.

[0012] Preferably, the drive source includes a fixedly mounted motor, two lead screws rotatable around their own central axes, and synchronous pulleys fixed to the same end of each lead screw. A synchronous belt is fitted onto each of the synchronous pulleys, and the synchronous belt meshes with the pulleys. Each lead screw has a threaded sleeve, and the two sleeves are connected and fixed to both sides of the cover plate body. The motor, through the synchronous belt and the engagement of the two pulleys, synchronously drives the two lead screws to rotate, thereby causing the sleeves on the lead screws to move back and forth along the axial direction of the two lead screws, smoothly moving the cover plate body horizontally.

[0013] Preferably, both ends of each lead screw are mounted on fixed seats, and each fixed seat contains a bearing. The two ends of each lead screw are rotatably mounted within two fixed seats via the bearings. The fixed seats are then fixedly mounted on the bioreactor or toilet seat. Attached Figure Description

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0019] See Figures 1 to 3 As shown, this embodiment discloses a biodegradable toilet seat, including a seat body 1. The seat body 1 is located between the bio-reaction chamber 17 and the toilet seat 18 of the bio-toilet. The seat body 1 is driven by a drive source to move back and forth in the horizontal direction to open or close the reaction chamber. A guide groove 2 is integrally formed on the upper end surface of the seat body 1. A guide channel 4 is provided below the guide port 3 of the guide groove 2. The guide channel 4 is fixed on the base 19 of the bio-toilet and is connected to a drain pipe 5.

[0020] A baffle 6 is integrally formed on the outer circumference of the cover body 1. The middle part of the cover body 1 protrudes upward, and the circumferential edge of the cover body 1 is recessed downward to form a guide groove 2. The baffle 6 is used to prevent urine from splashing on the cover body 1.

[0021] In this embodiment, the bottom of the guide channel 2 on one side of the guide channel 4 is lower than the bottom of the channel on the opposite side of the guide channel 4, so that the urine can flow better in the direction of the guide channel 4.

[0022] The guide port 3 is a straight section extension pipe with a cross-section of "U". The guide channel 4 has a guide cavity 7 inside and a slot 8 is opened on the side wall of the guide channel 4. When the cover plate body 1 moves back and forth horizontally, the straight section extension pipe can move back and forth in the direction of extending into the slot 8 and away from the slot 8. A guide outlet pipe 9 is provided at the bottom of the guide channel 4, and the lower end of the guide outlet pipe 9 is connected to the top of the drain pipe 5.

[0023] In this embodiment, the drainage channel 4 also has a buffer chamber 10 inside, which is connected to the drainage channel 7. The bottom of the buffer chamber 10 is higher than the bottom of the drainage channel 7, and the bottom of the buffer chamber 10 is inclined to the drainage channel 7. Since the outlet of the drainage channel 4 is small and the discharge speed is limited, the addition of the buffer chamber 10 expands the urine storage space.

[0024] like Figure 1 , Figure 2As shown, the drive source includes a fixedly mounted motor 11 and two lead screws 12 that can rotate around their own central axes. Synchronous pulleys 13 are fixed to the same end of each lead screw 12. Synchronous belts 14 are fitted onto the two synchronous pulleys 13 and mesh with them. Each lead screw 12 is threadedly engaged with a lead screw sleeve 20, and the two lead screw sleeves 20 are connected and fixed to both sides of the cover plate body 1. The motor 11 drives the two lead screws 12 to rotate synchronously through the synchronous belts 14 and the engagement of the two synchronous pulleys 13. This, in turn, causes the lead screw sleeves 20 on the lead screws 12 to move back and forth along the axial direction of the two lead screws 12, smoothly driving the cover plate body 1 to move horizontally. Each lead screw 12 has its two ends mounted on a fixed base 15, and each fixed base 15 contains a bearing 16. The two ends of each lead screw 12 are rotatably mounted within the two fixed bases 15 via the bearings 16. The mounting base 15 is fixedly installed on the bioreactor 17 or the toilet seat 18.

[0025] The working principle of this embodiment is as follows:

[0026] The cover body 1 is driven by the drive source to move horizontally to block the opening at the top of the bio-reaction chamber 17, thus closing the bio-reaction chamber 17. When a person urinates on the bio-toilet, the urine will be discharged through the guide channel 2 of the cover body 1 to the guide channel 4 and finally out of the drain pipe 5. When it is time to use the toilet, the cover body 1 is driven by the drive source to move horizontally in the opposite direction until the opening at the top of the bio-reaction chamber 17 is opened. At this time, the excrement discharged by the person on the bio-toilet falls directly into the bio-reaction chamber 17.

[0027] Furthermore, the working principle of the drive source is as follows: the motor 11 drives the two lead screws 12 to rotate synchronously through the synchronous belt 14 and the cooperation of the two synchronous pulleys 13. This causes the lead screw sleeves 20 on the lead screws 12 to move along the axial direction of the two lead screws 12 to one end, thereby causing the cover plate body 1 to move horizontally and thus opening the bioreactor 17. When closing the bioreactor 17, the motor 11 drives the two lead screws 12 to rotate in opposite directions, causing the lead screw sleeves 20 on the lead screws 12 to move along the axial direction of the two lead screws 12 to the other end, thereby causing the cover plate body 1 to move horizontally and thus closing the bioreactor 17.

[0028] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
