[0036] Please refer to Figures 1 to 16The nursing pants 10 of this design are worn on the lower body and are used to handle human excrement. The nursing pants 10 include an air cushion 11 for adhering to the lower body. The air cushion 11 is located in the crotch area of ​​the nursing pants 10 and forms a first opening 110 for human excretion. The air cushion 11 includes a first part 2, which is used to adhere to and support the buttocks of the human body. The first part 2 forms the base of the air cushion 11 and is inflatable, filled with a flexible padding material 112. When the nursing pants 10 are worn on the lower body and the body is lying flat, the first part... Part 2 is located on the lower side of the human buttocks, and under the pressure of the human buttocks, Part 2 and its internal flexible filler 112 are deformed. The presence of the flexible filler 112 helps to improve the support of the air cushion 11 for the human buttocks, and helps Part 2 to more reliably bear the pressure of the human buttocks after inflation, avoiding the fact that Part 2 is completely flattened under the pressure of the human buttocks, which would cause discomfort to the buttocks. The presence of the flexible filler 112 inside Part 2 helps Part 2 to more effectively cushion the pressure on the human buttocks, reducing the pressure and discomfort on the skin of the human buttocks, and improving the user experience of the air cushion 11.

[0037] The flexible filling material 112 can be a sponge pad, a latex pad, or a gel pad. When the nursing pants 10 are worn on the lower body and the body is lying flat, the first part 2 can be close to the coccyx of the buttocks. When the nursing pants 10 are worn on the lower body and the body is lying flat, the coccyx of the buttocks can directly compress the first part 2 and indirectly compress the flexible filling material 112 inside the first part 2. This arrangement can specifically improve the cushioning of pressure on the coccyx and reduce the pressure and discomfort on the skin of the coccyx.

[0038] In this embodiment, the flexible filler 112 is curved and forms a shape adapted to the first part 2. The flexible filler 112 includes a first flexible layer 1120 and a second flexible layer 1121 stacked together. The first flexible layer 1120 is located above the second flexible layer 1121. The resilience of the first flexible layer 1120 is weaker than that of the second flexible layer 1121. For example, the first flexible layer 1120 is made of slow-rebound sponge or slow-rebound latex, and the second flexible layer 1121 is made of fast-rebound sponge or ordinary sponge. The flexible filler 112 includes a first end 1122 and a second end 1123 opposite to each other. The flexible filler 112 bends and extends from the first end 1122 to the second end 1123. The first end 1122 forms the left rear end of the flexible filler 112, and the second end 1123 forms the right rear end of the flexible filler 112. The first end 1122 and the second end 1123 are located on the left and right sides of the first frame opening 110. This design allows the flexible padding 112 to better fit the first part 2, enabling the flexible padding 112 to more effectively indirectly bear the pressure of the human buttocks. When the nursing pants 10 are worn on the lower body and the body is lying flat, the first end 1122 and the second end 1123 are deformed under the pressure of the weight of the human buttocks.

[0061] The pull strap clamp 41 includes a pin 413, which passes through the first clamp arm 410. In this embodiment, the elastic reset member 412 is a torsion spring 412, which is sleeved on the pin 413.

[0062] The strap clip 41 includes a first connecting portion 414 and a second connecting portion 415, located on the left and right sides of the strap clip 41. A first clamping arm 410 is located between the first connecting portion 414 and the second connecting portion 415. A pin 413 passes through the first connecting portion 414, the first clamping arm 410, and the second connecting portion 415. The first clamping arm 410 is rotatably connected to the first connecting portion 414 and the second connecting portion 415 by means of the pin 413. The outer peripheral surface of one end of the pin 413 is a knurled surface 4130. One end of the pin 413 is inserted and fixed to the first connecting portion 414. The knurled surface 4130 is used for fixing the one end of the pin 413 to the first connecting portion 414. Based on the knurled surface 4130, the fixing firmness between the one end of the pin 413 and the first connecting portion 414 can be significantly enhanced.

[0063] The strap clip 41 also includes a third connecting portion 416, which is spaced apart from the second clamping arm 411. The first connecting portion 414, the second clamping arm 411, the second connecting portion 415, and the third connecting portion 416 are connected in sequence. The second clamping arm 411 is connected between the first connecting portion 414 and the second connecting portion 415, and the third connecting portion 416 is connected between the first connecting portion 414 and the second connecting portion 415. 415. The third connecting part 416 defines the third frame opening 417. The pin 413 is basically located in the third frame opening 417. The pull strap 510 can pass through the third frame opening 417. The torsion spring 412 includes a spring coil 4120 and a first leg 4121 and a second leg 4122 extending from the spring coil 4120 respectively. The spring coil 4120 is sleeved on the pin 413. The first leg 4121 presses against the first clamping arm 410, and the second leg 4122 presses against the third connecting part 416.

[0064] After the pull strap 510 disengages from between the first clamping arm 410 and the second clamping arm 411, under the force of the torsion spring 412, the first clamping arm 410 returns to its original position, directly abutting against the second clamping arm 411. The first clamping arm 410 includes a drive unit 4100, a first leg 4121 pressing against the drive unit 4100, and the first leg 4121 and the second leg 4122 located between the drive unit 4100 and the third connecting part 416. When the pull strap 510 is clamped by the first clamping arm 410... After being clamped by the second clamping arm 411, the first clamping arm 410 is rotated by pushing the drive unit 4100 toward the third connecting part 416 (e.g., pressing and pushing the drive unit 4100 with a finger), thereby widening the gap between the first clamping arm 410 and the second clamping arm 411 and releasing the pull strap 510. Releasing the pull strap 510 means releasing the clamping of the pull strap 510 by the first clamping arm 410 and the second clamping arm 411, and the released pull strap 510 can be removed from the pull strap clamp 41.

[0065] The first clamping arm 410 has a plurality of teeth 4101, which together with the second clamping arm 411 clamp the pull strap 510. The plurality of teeth 4101 can enhance the clamping stability of the pull strap clamp 41 on the pull strap 510.

[0066] The first clamping arm 410 can rotate in both the forward and reverse directions. When the drive unit 4100 is pushed toward the third connecting part 416, the first clamping arm 410 rotates in the same direction. During assembly, the free end 5100 of the pull strap 510 passes between the first clamping arm 410 and the second clamping arm 411. The free end 5100 of the pull strap 510 can be inserted between the first clamping arm 410 and the second clamping arm 411 from either side of the pull strap clamp 41 and gradually pass through. Therefore, there will be forward passing and reverse passing. In both scenarios, "forward" and "reverse" are relative terms, used only for clarity and distinction. When the free end 5100 of the pull strap 510 passes forward between the first clamping arm 410 and the second clamping arm 411, and the pull strap 510 is clamped by them, continuing to pull forward on the free end 5100 causes the first clamping arm 410 to deflect in the opposite direction of rotation due to friction. This causes the first clamping arm 410 and the second clamping arm 411 to... The clamping force of the pull strap 510 weakens, allowing it to pass more forward between the first clamping arm 410 and the second clamping arm 411. If the opposite end of the pull strap 510 is pulled in the opposite direction, the first clamping arm 410 tends to deflect in the direction of rotation (due to friction), thus increasing the clamping force between the first and second clamping arms 410 and 411. This results in a tighter clamping of the pull strap 510 between the first and second clamping arms 410 and 411. To prevent the pull strap 510 from coming loose, when attaching the pull strap 510 to the pull strap clip 41, the free end 5100 of the pull strap 510 needs to be passed through the first clip arm 410 and the second clip arm 411 in the forward direction and pulled to the required length as needed. If the free end 5100 of the pull strap 510 is passed through the first clip arm 410 and the second clip arm 411 in the reverse direction, the upper cover 51 cannot be effectively and reliably connected to the diaper 4, because pulling the upper cover 51 in this case will cause the pull strap 510 to come loose.

[0067] The lower cover 50 is provided with a first left-side restraint strap 501 and a first right-side restraint strap 502. The first left-side restraint strap 501 is provided with a second hook and loop fastener 5010.

[0068] The nursing pants 10 also include a first connector 520 in fluid communication with the inner cavity of the air cushion 11, a first nozzle 42 for spraying water, and a water supply pipe assembly 53. The water supply pipe assembly 53 is connected to the first nozzle 42 and is equipped with a one-way valve 530 and a second connector 531. The water supply pipe assembly 53 delivers water to the first nozzle 42 in one direction via the one-way valve 530. The one-way valve 530 is a normally closed valve. The water delivered by the water supply pipe assembly 53 can open the one-way valve 530 and flow to the first nozzle 42. The one-way valve 530 is in fluid communication between the second connector 531 and the first nozzle 42. 520 is compatible with the second connector 531 and can be connected together; this design helps to prevent water from entering the inner cavity of the air ring 11 during cleaning and maintenance. For example, when soaking for disinfection or cleaning with water, the first connector 520 and the second connector 531 can be connected together. Due to the presence of the one-way valve 530, even if the liquid flows back from the first nozzle 42, it will be blocked by the one-way valve 530 and cannot flow to the second connector 531 / first connector 520. This can prevent the liquid from flowing through the first connector 520 and further into the inner cavity of the air ring 11, thus preventing water from entering the inner cavity of the air ring 11.

[0069] The nursing pants 10 also includes an air supply tube assembly 52 that is in fluid communication with the inner cavity of the air cushion 11. The air supply tube assembly 52 includes the first connector 520, and the air supply tube assembly 52 can be connected to an external air supply pipeline device 80 via the first connector 520. The first nozzle 42 is disposed on the urine mask 4, forming the urine mask nozzle. The air cushion 11 can be inflated and deflated via the air supply tube assembly 52. ​​Specifically, when the air cushion 11 is inflated, gas is delivered to the inner cavity of the air cushion 11 via the air supply tube assembly 52; when the air cushion 11 is deflated, the air inside the air cushion 11 flows out through the air supply tube assembly 52. ​​The water supply tube assembly 53 also includes a first... The system consists of a water hose 532, a second water hose 533, an adapter 534, a one-way valve 530 connected to one end of the first water hose 532, a second connector 531 connected to the opposite end of the first water hose 532, the first water hose 532 connected between the one-way valve 530 and the second connector 531, the one-way valve 530 connected between the first water hose 532 and the second water hose 533, and the adapter 534 connected to the first nozzle 42 and the second water hose 533. The first water hose 532, one-way valve 530, second water hose 533, adapter 534, and first nozzle 42 are connected sequentially. This design prevents liquid from flowing further through the one-way valve 530, the first connector 520 and the second connector 531, and the air supply assembly 52 into the inner cavity of the air cushion 11 during cleaning and maintenance, thus preventing water from entering the air cushion 11 via the air supply assembly 52.

[0070] The diaper cover 4 is equipped with a positioning device 40, a strap clip 41 is positioned on the positioning device 40, a first nozzle 42 is disposed on the diaper cover 4 to form a diaper cover nozzle, the first nozzle 42 is fixed to the positioning device 40, and an adapter 534 is located inside the positioning device 40 and fixed to the positioning device 40. The positioning device 40 includes an outer shell 400 and an inner shell 401. The outer shell 400 is located outside the diaper cover 4, and the inner shell 401 is located inside the diaper cover 4. The inner shell 401 is attached to the inner surface of the diaper cover 4, and the outer shell 400 and the inner shell 401 are locked together and clamp a portion of the diaper cover wall of the diaper cover 4. The outer shell 400 and the inner shell 401 are locked together by several third screws 402. After the upper cover 51 is detachably connected to the urine cover 4, when the pull strap 510 is pulled, the pulling force is transmitted to the inner shell 401, causing the inner shell 401 to further press against the inner surface of the urine cover 4. The adapter 534 is located inside the outer shell 400 and is fixed together with the first nozzle 42. Furthermore, the adapter 534 and the first nozzle 42 are threadedly connected and fixed. The first nozzle 42 penetrates the cover wall of the urine cover 4, and the pull strap clip 41 is set on the outer shell 400. The urine cover 4 can be placed above the human genitals to receive human urine. When the urine collection device 1 is worn on the lower body and the human body is lying flat, the first nozzle 42 is located on the upper side of the lower body so as to spray water downward.

[0071] The diaper cover 4 is also provided with at least one air inlet 43, which is used to replenish air into the internal space of the diaper cover 4. The at least one air inlet 43 penetrates the cover wall and the inner shell 401 of the diaper cover 4. The at least one air inlet 43 is adjacent to the outer shell 400 and adjacent to the pull strap clip 41. The at least one air inlet 43 is located at the front end of the diaper cover 4.

[0072] The gas supply assembly 52 includes a gas supply hose 521 and a gas supply connector 522. The gas supply connector 522 is mounted on the second sealing member 31. One end of the gas supply hose 521 is connected to the first connector 520, and the other end of the gas supply hose 521 is fitted onto the first connector 520. The opposite end of the gas supply hose 521 is connected to the gas supply connector 522. When the gas cushion 11 deflates, the gas inside the gas cushion 11 flows sequentially through the gas supply connector 522, the gas supply hose 521, and the first connector 520. The gas supply connector 522 is integrally formed with the fourth cover plate 311, so both are made of the same material. The first water supply hose 532, the second water supply hose 533, and the gas supply hose 521 can be made of silicone hoses. The gas supply connector 522 constitutes the air nozzle of the gas cushion 11, and the gas supply connector 522 can also be considered as part of the gas cushion 11.

[0073] The air inlet connector 522 is located on the top side of the air cushion 11 and in front of the urine mask 4. The air inlet hose 521 and the air inlet connector 522 are adjacent to the urine mask 4. This arrangement facilitates the movement of the air inlet hose 521. The air inlet connector 522 is offset to the left or right relative to the urine mask 4 on the fourth cover plate 311 so that the air inlet hose 521 can avoid the urine mask 4 without excessive bending and adjustment of the air inlet hose 521. The third cover plate 310 has a clearance hole 3102 for accommodating the end 5220 of the air inlet connector 522, which is connected to the inner cavity of the air cushion 11.

[0074] The nursing pants 10 also include a decorative piece 132, which covers the second closure 31 to prevent it from being exposed, thus improving its appearance and preventing the aforementioned second screws 115 on the second closure 31 from being exposed. The decorative piece 132 is glued to the second closure 31. The decorative piece 132 has a first through hole 1320, through which the air supply pipe assembly 52 and the air supply connector 522 pass.

[0075] The air cushion body 113 forms an integrally molded annular three-dimensional airbag. Furthermore, the air cushion body 113 forms an integrally molded annular three-dimensional airbag having at least one draft hole. The air cushion 11 is in its inflated, unused state (this unused state corresponds to the state where the nursing pants 10 are assembled but not worn on the body (see...)). Figure 4 , Figure 6 As shown), the air cushion 11 needs to be properly inflated for inspection; it should be noted that the nursing pants 10 are usually worn on the body with the air cushion 11 uninflated, and then inflated for use. The air cushion 114 is in a first fold shape that can fit the lower body (see...). Figure 4 , Figure 6 As shown), it can effectively and closely conform to the lower body without excessive deformation; in its original state after inflation (this original state corresponds to the air cushion 114 not yet being connected to the other components of the nursing pants 102, so the air cushion 114 is in an independent state where its shape is not constrained by the other components), the shape of the air cushion 114 is basically not restricted by external objects, thus restoring its original shape. Figure 13 As shown), the air cushion 114 has a second fold shape adapted to the lower body of the human body (see figure). Figure 13As shown), the first bend shape is consistent with the second bend shape (i.e., the shapes are basically the same). If the shape of the air cushion 114 in its inflated, unused state differs significantly from that in its original inflated state, even if the air cushion 114 in its original inflated state has few wrinkles, it is highly likely that the air cushion 114 in its inflated, unused state will have several wrinkles due to the large shape change compared to its original inflated state. These wrinkles will result in poor sealing between the air cushion body 113 and the human skin, and may even pinch the skin and flesh, leading to poor fit and sealing of the air cushion 114 against the human skin and poor comfort. This design improves the fit and sealing of the air cushion 114 against the human skin and improves comfort. In the inflated, unused state, the exposed surface of the air cushion body 113 (i.e., the exposed surface) is wrinkle-free, resulting in better fit and sealing against the skin of the lower body and higher comfort during use.

The electrical connector 140 is located at the free end of the power transmission cable 14. The waterproof sealing cap 15 is used to cover the electrical connector 140 and seal and store the electrical connector 140, thereby providing waterproof sealing protection for the electrical connector 140. For example, when the waste collection container 7 is soaked for disinfection or cleaned with water, the waterproof sealing cap 15 seals and stores the electrical connector 140, preventing the electrical connector 140 from contacting liquid and avoiding rust and corrosion. The urination sensor, defecation sensor, turning angle sensor, circuit board, etc. inside the toilet 7 all require electricity, and all require the power supply cable 14 and its electrical connector 140 to supply power. The waterproof sealing cap 15 has a hanging hole 150. In order to prevent the waterproof sealing cap 15 from being lost, a rope can be tied through the hanging hole 150.
