Description

Technical Field

[0001] Involving the field of sanitary ware technology, it focuses on solving the pain points of defecation privacy and hygiene cleaning, and post-defecation disposal in outdoor scenarios such as the field, emergency, and special operations, as well as the high cost of using indoor toilets. Background Technology

[0002] The pain points related to toileting, cleaning, and disposal can be summarized into four categories: 1. Outdoor privacy and disposal (Problem 1): In the wild and scenic areas where there are many people and few toilets, the risk of privacy exposure during defecation is high, and the random disposal of feces pollutes the environment. Traditional tools have limited functionality. 2. Indoor usage costs (Question 2): Traditional toilets have high installation costs, require a matching drainage system, and have high daily maintenance and cleaning costs, making them unsuitable for temporary residences (such as apartments or basements) or low-cost living scenarios; 3. Functions and Operation (Question 3): Existing defecation tools lack spill prevention and easy cleaning designs, have no manual / electric mode selection, and cannot adapt to the usage habits of different people.

[0003] 4. People's hygiene habits (Question 4): There is room for improvement in defecation, cleaning, and disposal in different parts of the world.

[0004] There is an urgent need for an innovative product that integrates "indoor toilet replacement, outdoor compliant defecation, manual and electric dual modes, and changes in people's hygiene habits" to fill the gap in related solutions. Summary of the Invention

[0005] A portable indoor / outdoor urinal (a divisional application, original application number: 2025111708144, referred to here as a "urinal," please refer to its contents for details on urination) is mainly used for indoor and outdoor defecation scenarios, supplementing the urinal in my patent (in this application, urine is processed in the urinal opening and urinal cavity, with simple adaptive modifications to the water pipe and air duct). Its features include three parts: an inflatable body covering, a core defecation unit, and a post-defecation disposal tool. It supports both manual (traditional mode) and electric (mobile APP control) modes, realizing three steps: "1. Preparation (wearing the inflatable cover) - 2. Defecation (dual-cavity wings + negative pressure suction + water and air cleaning) - 3. Disposal (direct burial / compliant disposal)." Technical solution (a) Inflatable body covering

[0006] Similar to a raincoat or poncho, but larger, it features a lightweight, foldable, inflatable design. Most of the material is opaque, waterproof TPU fabric. The upper part covers the head but leaves the eyes exposed, while the lower part has an open, skirt-like structure (or a canopy-like structure, with the arms and hands also inside). The bottom is supported by a ring-shaped inflatable tube with a diameter of about 100-200cm and a tube diameter of about 2cm. The body covering is equipped with a quick inflation valve (using a foot-operated or electric air pump). After inflation, the person can use the body covering to defecate inside. After use, it can be folded up. It is lightweight, compact, and easy to carry. (II) Core defecation unit

[0007] Double-cavity winged defecation bag: similar to shopping bags with a single handle (2) in shopping malls, it is sturdy enough, and there are different sizes for men and women. It is made of biodegradable PLA material with appropriate thickness, except that most of its top is sealed with plastic film. It has a certain degree of elasticity and can stretch. There is a positioning protrusion (6) about 0.6cm high on the top, with a large defecation opening and a small urination opening. The defecation opening is concave downward to facilitate cleaning. There are dozens of plastic protrusions about 0.3cm high near it to facilitate friction and cleaning. It has wide wings on both sides (like sanitary napkins). When the user sits down, the wings are pressed against the thighs to keep the defecation opening fixed open and prevent the defecation bag from slipping and the feces from overflowing). Inside the bag is a plastic film (like the interlayer in a small bag) that divides the defecation bag into a fecal cavity (7) and a urinary cavity (5), which are connected to the fecal opening and the urinary opening respectively; the inner walls of the fecal cavity and the urinary cavity are equipped with a cleaning and drying structure, and come with a section of plastic water pipe (9) and a section of air pipe (4) that do not obstruct the anus and urethra, which can be connected to the corresponding water pipe and air pipe from the outside; the urinary cavity is smaller, and a small hole is opened at its lower part to allow urine to flow to the bottom of the defecation bag, so there is very little interference between the two cavities; the defecation bag is about 40cm high (similar to the height of a toilet, the top should accommodate the genitals, and the bottom is columnar), and the bottom is supported by the ground or other objects; During defecation, guide the positioning protrusion (6) to accurately align the anus with the stool opening (7); after defecation, there are three ways to clean: 1. You can use your hand to gently rub the plastic bumps on the stool bag from below, using short, light strokes, while also washing the anus with water (either a clean wash or a water wash, but since this is done through the plastic film, it should be cleaner than using toilet paper and more readily accepted). 2. Cleaning with a micro-motor assisted through a plastic film (an alternative solution, the micro-motor driven cleaning device includes a micro-vibration motor installed on the outer wall of the defecation bag and on the toilet support stool. The motor is connected to the protrusions on the inner wall of the bag through an elastic connector to achieve hygienic and safe non-contact cleaning. See the micro-vibration motor of massage chairs and electric toothbrushes, and the ultrasonic cleaning principle, which uses the high-frequency vibration of ultrasonic cleaning equipment or the reciprocating vibration of electric toothbrushes, with the external vibration motor driving the internal protrusions); there are handles (2) on both sides of the bag (for easy operation by pulling the handles back and forth, similar to pulling the ends of a towel to clean the crotch when taking a bath); the bag body integrates a negative pressure air extraction port (connected to a micro negative pressure pump, optional), a water pipe interface (9, for connecting a water bottle on the back), and an air duct interface (4, for connecting a fan in front of the body) (water pipes and air ducts can be added as needed and led to the relevant genital positions); Thirdly, the plastic water pipe on the top of the toilet can be replaced with a plastic water pipe rod (14) with a certain degree of hardness. Its front end is located behind the defecation opening, with a protrusion (13) and a spray nozzle (12) on it. It can be connected to a water bottle and its water pipe (9). Water can be sprayed through the pressure handle, which can better move back and forth and rotate clockwise and counterclockwise to clean the anus.

[0008] The top or sides of the defecation bag are provided with a self-sealing strip (11) for sealing after defecation (refer to the self-sealing strip on the plastic self-sealing bag).

[0009] Toilet support stool (1): The toilet support stool is similar to a toilet with a wide gap in the middle. It adopts a lightweight folding structure for easy carrying. When defecating, the stool bag wings are spread flat on it and you sit on it to press it down.

[0010] Negative pressure defecation module: A miniature negative pressure pump (optional) is connected to the negative pressure suction port of the double-chamber winged defecation bag through a pipeline. The negative pressure value generated ranges from -5kPa to -20kPa. After starting, it forms negative pressure at the defecation port to assist defecation.

[0011] Water and air coordinated cleaning module: A replaceable water bottle is provided on the back, which is connected to the cleaning nozzle of the double-cavity winged toilet bag through a water pipe (9); a portable fan is provided at the front, which is connected to the air drying port of the double-cavity winged toilet bag through an air pipe (4); the module can be started and stopped by a mobile APP (electric mode). (iii) Tools for post-defecation disposal

[0012] Multi-functional shovel: Made of lightweight material, the shovel head has a depth mark (compliant with the legal depth of >20cm for outdoor burial of feces), and the handle integrates a temporary storage slot for feces bags (can hold folded, empty feces bags).

[0013] Working principle

[0014] Users bring their own miniature power supply and can choose between manual or electric modes as needed: in electric mode, each module is controlled via a mobile app; in manual mode, each component is operated manually. After inflating and unfolding the body covering, place the double-chamber winged defecation bag on the toilet seat support stool, using the positioning protrusions to accurately align the anus with the defecation opening and the urethra with the urination opening; during defecation, activate the negative pressure suction module (optional) to assist defecation; after defecation: in manual mode, there are three ways to clean the diaphragm with water; in electric mode, activate the micro motor to assist in cleaning and the water-air module via the mobile app; after cleaning and drying, seal the defecation bag directly with the sealing strip. In outdoor scenarios, bury it in a pit with a shovel; in indoor scenarios, take it out for compliant disposal, completing the entire process.

[0015] Beneficial effects Compared to the current situation (urinating outdoors, queuing for toilet stalls, using indoor toilets, and using toilet paper for cleaning), this application offers relative freedom in outdoor urination, and allows for washing and drying of the genitals with water and air, making it more hygienic; the waste bags used to collect feces are water-saving, cost-effective, maintenance-free, easy to dispose of, and convenient to use. Regarding water conservation, each use requires less than 1 liter, roughly the amount of a bottle of mineral water, which is much more economical than the 6 liters required for a toilet.

[0016] 1. Functional complementarity and scenario adaptation: This application mainly relates to the equipment and method for defecation, which complements the urination device in my patent; it supports both indoor and outdoor scenarios, and can replace the toilet indoors, while reducing the need to build public toilets outdoors; 2. Dual-mode adaptation: The manual mode adapts to traditional usage habits and is highly reliable; the electric mode is controlled via a mobile app (based on existing technology upgrades, unlike smart toilets), covering the needs of different users. 3. Hygiene and environmental protection are both taken into account: Double-cavity wings prevent spillage, and raised dots + micro motor and ultrasonic-assisted cleaning (electric mode) enhance convenience; the biodegradable sewage bag can be directly buried, which greatly benefits the fertilization and watering of nearby plants, especially trees (new management measures are required). 4. Safe and convenient operation and privacy protection: The three steps of "preparation-defecation-disposal" are clear, the structure is simple and safe, the inflatable body covering creates an independent private space, the folding design is easy to carry, and it can replace a raincoat for rain protection; 5. Significant social value: fewer public toilets need to be built outdoors, reducing infrastructure investment and saving social costs; indoor toilets can replace toilets, reducing housing costs and adapting to temporary or low-cost housing scenarios.

[0017] 6. Modern technology improves traditional habits: Around the world, some regions use hand washing (or water washing) after defecation, while others use only toilet paper. Those who can afford expensive smart toilets remain a minority. This application uses water washing, but through a plastic film, avoiding the residue left by using only toilet paper without water, making it more acceptable to people. This is a change in customs, achieving great things with little expense.

[0018] 7. Significant Innovation and Easy Promotion: This application solves three major pain points—difficulty in finding a toilet outdoors, leakage prevention, cleaning and drying of excrement, and simplified sanitation—through a combination of innovative technologies: "inflatable portable body covering + double-cavity winged anti-overflow excrement bag + convex friction + feng shui cleaning + direct sealing and burial." Unlike existing technologies with their single-function limitations, this application solves a problem that people have long wanted to solve but have been unable to (news reports of toilet difficulties are common during peak tourist seasons). It provides a new alternative to toilets for living spaces without toilets, such as basements. The excrement bag is inexpensive, the cleaning method is hygienic, and it is easily accepted by people, making it easy to promote. Attached Figure

Detailed Implementation

[0020] Operating procedures 1. Preparation stage: Select mode: Manual mode prepares parts directly; Electric mode connects to the mobile APP (pairs the device). Wear the inflatable bodysuit: Take out the folded bodysuit, inflate it with the air pump, adjust the lower skirt-like structure to unfold, and cover your head and eyes while covering your body; Assemble the core unit: unfold the toilet support stool (1), lay the stool bag wings flat on the stool, sit down and press the wings on both sides, use the positioning protrusions (6) to make the anus accurately aligned with the stool opening (7), and then make the urethra aligned with the urinary cavity (5); in electric mode, connect each module through the APP. Prepare the tools: Place the shovel within easy reach.

[0021] 2. Defecation stage: Zoned defecation: Activate the negative pressure defecation module to assist defecation (optional, the negative pressure suction port is located slightly below the defecation port), and complete the discharge of defecation (through defecation port 7) and urine (through urine port 5) separately; Cleaning and drying: Cleaning method: Wipe the stool through the plastic film (like using toilet paper) and rinse with water. The purpose of the raised plastic dots is to increase friction at the contact point near the anus and prevent the skin from sticking to the stool bag. The stool bag is manufactured by pressing raised dots and textures onto the surface of the anus area using an embossing roller.

[0022] Manual mode: Three modes: One method is to use one hand to gently press the raised dots directly through the plastic film to wipe away feces, while pinching the water pipe head to control the flushing water volume. Secondly, hold the front handle with your left hand and the back handle with your right hand, and pull the toilet bag back and forth slightly to rub it. Use your right hand to pinch the water pipe to control the water volume (9) for cleaning. Then turn on the fan (4) to dry it. Thirdly, the plastic water pipe on the top of the toilet is replaced with a plastic water pipe rod (14) with a certain degree of hardness. Its front end is located behind the defecation opening, with a protrusion (13) and a spray nozzle (12) on it. A water bottle and its water pipe (9) are connected to it. When cleaning after defecation, one hand can be used to move the water pipe rod back and forth and rotate it clockwise and counterclockwise to rub the anus. At the same time, press the pressure handle (15) on the integrated water pipe (modify the common spray bottle, in which case the water pipe rod is similar to a nozzle) to spray water, which can better clean the anus.

[0023] Electric mode: The portable miniature power supply is connected to a mobile app to start a micro motor to assist in cleaning, water pipe cleaning, and fan drying. When the motor starts, the short-distance movement or high-frequency vibration generated is transmitted to the protrusions, causing them to make slight reciprocating movements on the inner wall of the bag, thereby achieving friction cleaning of the anus.

[0024] Sealing the bag: Close the relevant module and seal it with the self-sealing strip (11) on the bag (which can also be made on the side wings).

[0025] 3. Disposal Phase: Disposing of excrement bags: In outdoor settings, use a shovel to dig a pit of the required depth, place the sealed excrement bag directly into the pit and bury it, leaving some handle marks on the ground, or use other methods to remind others not to step on it accidentally; In indoor settings, dispose of the excrement bag in accordance with compliance requirements. Storage tools: folding toilet seat, deflated and stored body covering, storage shovel, to complete the entire operation.

[0026] The implementation of this application is not limited to the above embodiments. Various modifications and changes can be made without departing from the spirit and scope of this application, such as: biodegradable defecation bags, since the current biodegradability time is still too long, or other materials such as suitable paper materials can be used instead.

[0027] The scope of protection of this application is defined by the claims, and any equivalent substitutions or modifications shall be included within the scope of protection of this application. This application does not claim traditional methods that involve simple mechanical expansion of the handle, defecation into ordinary plastic bags, and cleaning with toilet paper.
