Description

Technical Field

[0001] This invention relates to the field of household products, specifically to a toilet paper sterilization and carbonization treatment box. Background Technology

[0002] In existing technologies, bathrooms, due to their warm, humid, and poorly ventilated characteristics, are prone to odors and microbial growth. There are two main methods for disposing of toilet paper used after using the toilet:

[0003] The first method is to discard toilet paper in an open trash can in the bathroom. Since toilet paper typically carries moisture and excreted organic matter, its accumulation in the bathroom easily creates a breeding ground for bacteria, mold, and other microorganisms. This not only leads to the release of volatile odor substances such as ammonia and hydrogen sulfide, affecting indoor air quality, but also poses a potential risk of biological contamination and cross-infection. Furthermore, this method fails to reduce waste volume at the source, increasing the consumption of plastic garbage bags and the frequency and burden of subsequent garbage collection.

[0004] The second method is to flush the toilet directly. While this avoids temporary storage indoors, its successful disposal heavily relies on a sufficient volume of water, a high flow rate in the drain pipes, and the rapid dispersibility of the toilet paper itself. In practical applications, especially in older homes, with water-saving toilets, or in areas with poor drainage networks, toilet paper is prone to incomplete dissolution and can adhere to and entangle in pipe bends. Long-term accumulation may lead to blockages, causing maintenance problems for users and potentially triggering public sewage issues.

[0005] To address the aforementioned issues, some devices on the market aim to improve toilet paper disposal, such as small shredders with built-in cutting mechanisms or airtight trash cans. However, these existing devices either only perform simple physical cutting, failing to effectively inactivate pathogenic microorganisms and lacking sufficient hygiene and safety performance; or they suffer from problems such as complex structure, high energy consumption, excessive noise, or high cost, making it difficult to promote and popularize them on a large scale in ordinary household environments.

[0006] Therefore, there is an urgent need in this field for a toilet paper processing device that can integrate efficient crushing, thorough sterilization, and final volume reduction. Summary of the Invention

[0007] In view of this, the present invention proposes a toilet paper sterilization and carbonization treatment box, which can realize the immediate, on-site, harmless and volume reduction treatment of toilet paper, fundamentally eliminating hygiene hazards and replacing traditional toilet trash cans.

Detailed Implementation

[0044] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0045] Please see Figures 1 to 6This invention discloses a toilet paper sterilization and carbonization treatment box, including a box body 10, a hopper 20, a crushing mechanism 30, a carbonization unit 40, a metering valve 50, and a controller 70.

[0046] like Figure 1 and Figure 2 As shown, the housing 10 is a square housing with an open top. The hopper 20 is fixedly installed at the top of the inner cavity of the housing 10 for receiving and temporarily storing toilet paper to be processed. Specifically, the hopper 20 includes, from top to bottom: a conical feeding section 201 with a rectangular cross-section, a cylindrical crushing section 202 connected to the lower end of the conical feeding section 201, a conical guide section 203 connected to the lower end of the cylindrical crushing section 202, and a cylindrical discharge pipe 204 connected to the lower end of the conical guide section 203. The crushing mechanism 30 includes a crushing component located at the lower part of the hopper 20 for crushing the toilet paper in the hopper 20 and a drive component for driving the crushing component. Specifically, the crushing assembly is located inside the cylindrical crushing section 202, and the metering valve 50 is installed at the outlet of the cylindrical discharge pipe 204 to quantitatively convey the paper scraps processed by the crushing mechanism 30 downwards. The carbonization unit 40 is fixedly installed inside the housing 10 and located below the metering valve 50. The top inlet of the carbonization unit 40 is connected to the outlet of the metering valve 50, and the bottom of the carbonization unit 40 is provided with an ash outlet. The controller 70 is electrically connected to the metering valve 50, the crushing mechanism 30, and the carbonization unit 40 respectively, and is used to control each component to work according to a preset program.

[0047] When using the toilet paper sterilization and carbonization treatment box of the present invention, the user puts the toilet paper into the hopper 20, and the crushing mechanism 30 is activated to crush the toilet paper into small paper scraps. Then, the metering valve 50 opens in stages according to the instructions of the controller 50, sending a metered amount of paper scraps into the carbonization unit 40 below. The paper scraps undergo a high-temperature carbonization process in the carbonization unit 40, are thoroughly sterilized and transformed into sterile ash. Finally, the ash is discharged through the ash outlet at the bottom of the carbonization unit 40.

[0048] This invention provides a toilet paper sterilization and carbonization treatment box, which automates the feeding, crushing, quantitative feeding, carbonization and sterilization, and ash discharge of toilet paper. It avoids the problem of temporary storage or flushing of used toilet paper, fundamentally solves the problems of odor and bacterial growth caused by the accumulation of waste toilet paper, and achieves waste reduction at the source.

[0049] like Figure 3As shown, the shredding assembly includes a first rotating shaft 301 and a second rotating shaft 304 arranged in parallel. Both the first rotating shaft 301 and the second rotating shaft 304 are rotatably supported horizontally between the two side walls of the hopper 20. A plurality of first large-diameter shredders 302 and first small-diameter shredders 303 are fixedly sleeved on the first rotating shaft 301, and the first large-diameter shredders 302 and the first small-diameter shredders 303 are alternately arranged along the axial direction of the first rotating shaft 301. A plurality of second large-diameter shredders 305 and second small-diameter shredders 306 are fixedly sleeved on the second rotating shaft 304, and the second large-diameter shredders 305 and the second small-diameter shredders 306 are alternately arranged along the axial direction of the second rotating shaft 304. The rotation trajectory of the first large-diameter shredder 302 and the rotation trajectory of the second small-diameter shredder 306 maintain a cutting gap in the radial direction, and the rotation trajectory of the second large-diameter shredder 305 and the rotation trajectory of the first small-diameter shredder 303 also maintain a cutting gap in the radial direction.

[0050] In this embodiment, the opposite sidewalls of the cylindrical crushing section 202 are provided with through holes for the first rotating shaft 301 and the second rotating shaft 304 to extend out of the cylindrical crushing section 202. Bearings are fixedly installed in the through holes, and the first rotating shaft 301 and the second rotating shaft 304 are rotatably engaged with the corresponding bearings, allowing the first rotating shaft 301 and the second rotating shaft 304 to rotatably pass through the cylindrical crushing section 202. The first large-diameter paper shredder 302 and the second large-diameter paper shredder 305 have the same structure, and the first small-diameter paper shredder 303 and the second small-diameter paper shredder 306 have the same structure, and all are ring blades. A cutting gap of 1-5 mm is maintained between the first large-diameter paper shredder 302 and the second small-diameter paper shredder 306, and between the second large-diameter paper shredder 305 and the first small-diameter paper shredder 303. The staggered layout of large-diameter blades to small-diameter blades greatly increases the cutting point density, avoids material entanglement or jamming that may occur when blades of the same diameter cut against each other, thereby improving crushing efficiency and reliability, and ensuring the uniformity of paper scraps.

[0051] like Figure 3 As shown, the drive assembly includes a motor 307, a driving gear 308, and a driven gear 309. The driving gear 308 is fixedly mounted on one end of the first rotating shaft 301 and rotates synchronously with it. The driven gear 309 is fixedly mounted on the corresponding end of the second rotating shaft 304 and rotates synchronously with it. The driving gear 308 and the driven gear 309 mesh with each other to form a gear transmission mechanism. The motor 307 is fixedly mounted on the housing 10 or the hopper 20, and the output shaft of the motor 307 is connected to the end of the first rotating shaft 301 to drive the first rotating shaft 301 to rotate, thereby driving the second rotating shaft 304 to rotate synchronously in the opposite direction through the gear transmission mechanism. Preferably, the motor 307 is a servo motor. The output shaft of the servo motor drives the first rotating shaft 301 to rotate through a coupling, thereby driving the second rotating shaft 304 to rotate synchronously in the opposite direction through a gear pair. This structure allows the drive assembly to drive the dual shafts to rotate in opposite directions with only one motor, resulting in a compact structure and low energy consumption.

[0052] like Figure 5 As shown, the carbonization unit 40 includes a carbonization tank 401. The inner cavity of the carbonization tank 401 is provided with the following components from top to bottom: a first fixing mesh 402, a second fixing mesh 405, a spiral guide vane 403, a first heater 404, and a second heater 406. The first fixing mesh 402 is horizontally fixed to the upper part of the inner cavity of the carbonization tank 401, and the second fixing mesh 405 is horizontally fixed to the lower part of the inner cavity of the carbonization tank 401. The upper and lower ends of the spiral guide vane 403 are fixedly connected to the first fixing mesh 402 and the second fixing mesh 405, respectively. The first heater 404 is arranged around the inner wall of the carbonization tank 401, and its heating area corresponds to the space occupied by the spiral guide vane 403. The second heater 406 is disposed on the second fixing mesh 405.

[0053] In this embodiment, both the first heater 404 and the second heater 406 are electric heaters. The first heater 404 is a heating wire or heating tube that surrounds the inner wall of the carbonization tank 401. Its heating area covers the axial space where the spiral guide plate 403 is located, providing the main heat required for carbonization. The second heater 406 is an electric heat lamp that can finally burn off the ash accumulated at the bottom of the carbonization tank to ensure thorough sterilization.

[0054] In this embodiment, the spiral guide plate 403 is provided with multiple ash-collecting holes 4031, which are evenly distributed along the spiral surface of the spiral guide plate 403. The spiral guide plate 403 allows paper scraps to slowly fall along the spiral path, extending the residence time of the paper scraps in the high-temperature zone, that is, extending the carbonization path. The diameter of the ash-collecting holes 4031 is not less than 5 mm and not more than 10 mm, and some fine ash can fall through the ash-collecting holes 4031. This process makes the paper scraps constantly turn and mix, thereby realizing dynamic carbonization and ensuring uniform heating and carbonization effect.

[0055] like Figure 5 and Figure 6As shown, the center of the lower surface of the second fixed mesh 405 is provided with a ash discharge switch 60 for opening and closing the ash outlet. The ash discharge switch 60 includes an outer cylinder 601, a pull rod 603 and an elastic element 606. The upper end of the outer cylinder 601 is fixedly connected to the center of the second fixed mesh 405. The lower end of the outer cylinder 601 is threadedly connected to an end cap 602. The center of the end cap 602 is provided with a through hole for the pull rod 603 to pass through. The upper end of the pull rod 603 is fixedly connected to a pressure plate 604 that can slide up and down inside the outer cylinder 601. The rod of the pull rod 603 is movably inserted through the through hole of the end cap 602. Its lower end is connected to a sealing block 605 for sealing the ash outlet. An elastic element 606 is sleeved on the outer wall of the pull rod 603. The upper end of the elastic element 606 abuts against the lower surface of the pressure plate 604, and the lower end abuts against the upper surface of the end cap 602, providing a continuous upward elastic sealing force for the pull rod 603 and the sealing block 605, so that the sealing block 605 keeps the ash outlet closed in its natural state.

[0056] In this embodiment, the elastic element 606 is preferably a compression spring, and the sealing block 605 is preferably a frustum structure. When the weight of the ash accumulated at the bottom of the carbonization tank 401 exceeds the preload of the elastic element 606, the pull rod 603 is pressed down, and a gap is formed between the sealing block 605 and the ash outlet, allowing the ash to be discharged. When the weight of the ash decreases, the sealing block 605 re-closes the ash outlet under the reset action of the elastic element 606. This structure ensures that a small amount of ash is always present at the bottom of the carbonization tank 401, forming an ash seal, effectively preventing a large amount of external air from entering the carbonization tank 401, and maintaining the high-temperature and oxygen-deficient environment required for carbonization.

[0057] In this embodiment, a temperature sensor is also installed inside the carbonization tank 401. The temperature sensor is electrically connected to the controller 70. The temperature sensor is used to detect the temperature inside the carbonization unit 40 and feed the temperature signal back to the controller 70. When the detected temperature reaches the set value (e.g., 550°C), the first heater 404 and the second heater 406 are turned off. When the temperature is lower than the set value, the heating is restarted to stabilize the temperature inside the carbonization tank in the optimal carbonization range until the preset carbonization time is completed. This temperature control not only ensures the sterilization and carbonization effect but also improves energy efficiency.

[0058] In this embodiment, a pull-out ash collection box 101 is provided at the bottom of the box 10. The receiving cavity of the ash collection box 101 is arranged vertically and vertically with the ash outlet at the bottom of the carbonization unit 40. The ash collection box 101 is used to receive and store the ash after carbonization. When it accumulates to a certain amount, it can be pulled out, the ash can be poured out, and it can be reinserted into the box 10 for continued use.

[0059] This invention relates to a toilet paper sterilization and carbonization treatment box. Through the integrated design of paper scrap crushing, quantitative feeding, spiral flow carbonization, and automatic ash discharge, toilet paper is converted into a very small amount of sterile ash, which greatly reduces the amount of waste. Moreover, the entire process from feeding to ash discharge can be automatically controlled without manual intervention, making it convenient and hygienic to use. The high-temperature carbonization process can completely inactivate all pathogenic microorganisms and eliminate the risk of biological contamination.

[0060] The technical solution of the present invention has been described in detail above with reference to specific embodiments. The specific embodiments described are used to help understand the concept of the present invention. Derivations and modifications made by those skilled in the art based on the specific embodiments of the present invention also fall within the scope of protection of the present invention.
