[0010] Referring to FIGS. 1 to 12, the excrement collection assembly of the present application includes a pants device 10 and a working head 11. The excrement collection assembly is used for nursing equipment. The pants device 10 is worn on the human body. The pants device 10 includes a connection bracket 3 and a crotch opening 34 where the human body excretes. The connection bracket 3 is located at the crotch part of the pants device 10 and surrounds the connection bracket 3 so as to form at least a part of the crotch opening 34. The connection bracket 3 includes an air inlet 370, an air outlet 371 and a gas flow path. The gas flow path communicates the air inlet 370 and the air outlet 371. Based on the air inlet 370, the gas flow path, and the air outlet 371 that communicate with each other, the connection bracket 3 of the pants device 10 itself is provided with an air flow path. When the air pressure at the air outlet 371 is smaller than the air pressure at the air inlet 370, the air at the air inlet 370 can be replenished to the air outlet 371 via the gas flow path. Thus, the connection bracket 3 of the pants device 10 itself is provided with a flow path through which gas passes, has higher applicability, and the connection bracket 3 can be made of a plastic material.

[0011] The connection bracket 3 is for docking the pants device 10 and the working head 11 of the care equipment. When in use, the pants device 10 is worn on the human body. In order to receive human excrement, the working head 11 is docked to the connection bracket 3 of the pants device 10, which is equivalent to the working head 11 being indirectly worn on the human body through the pants device 10. The working head 11 includes an excrement container 40 for accommodating human excrement. In a state where the connection bracket 3 is docked to the working head 11, the exhaust port 371 of the connection bracket 3 is adjacent to the excrement container 40, facilitating the airflow at the exhaust port 371 to replenish the excrement container 40. After the excrement collection assembly is worn on the human body, the human body can excrete excrement such as feces into the excrement container 40 through the crotch opening 34. The connection bracket 3 is in an annular shape and surrounds the crotch opening 34. Viewed from another angle, the opening of the frame surrounded by the connection bracket 3 constitutes the crotch opening 34. The air inlet 370 is located on the outer peripheral part of the connection bracket 3, and the exhaust port 371 is located on the inner peripheral part of the connection bracket 3.

The left flow path 372 penetrates through the inside of the left connecting part 363, and the right flow path 373 penetrates through the inside of the right connecting part 364. The left connecting part 363 is hollow, and the internal space of the left connecting part 363 constitutes a part of the left flow path 372. The right connecting part 364 is hollow, and the internal space of the right connecting part 364 constitutes a part of the right flow path 373.

[0015] The second U-shaped part 362 further includes a partition part 390. The partition part 390 divides the intake port 370 into a left half part 3700 and a right half part 3701. The left flow path 372 correspondingly communicates the left half part 3700 of the intake port 370 and the exhaust port 371, and the right flow path 373 correspondingly communicates the right half part 3701 of the intake port 370 and the exhaust port 371. The partition part 390 further promotes the diversion of the air flow.

[0016] The connection bracket 3 is hollow, so that a gas flow path is formed inside the connection bracket 3. Therefore, the gas flow path can also be called an air flow cavity. The left flow path can also be called the left cavity, and the right flow path can also be called the right cavity. The connection bracket 3 includes a first frame body 380 and a second frame body 381. Each of the first frame body 380 and the second frame body 381 is an integrally formed one-piece component. The first frame body 380 and the second frame body 381 can be made of plastic materials. The first frame body 380 and the second frame body 381 are each in an annular shape. The first frame body 380 and the second frame body 381 are combined to form the connection bracket 3. The left half of the first frame body 380 and the left half of the second frame body 381 are combined, and the left flow path 372 is formed between the left half of the first frame body 380 and the left half of the second frame body 381. The right half of the first frame body 380 and the right half of the second frame body 381 are combined, and the right flow path 373 is formed between the right half of the first frame body 380 and the right half of the second frame body 381. In this embodiment, the partition 390 belongs to a part of the second frame body 381.

[0017] The pants device 10 further includes a through hole 1070. The air inlet 370 is fluidly communicated between the through hole 1070 and the gas flow path. The through hole 1070, the air inlet 370, the gas flow path, and the exhaust port 371 are sequentially communicated. When the air pressure at the exhaust port 371 is smaller than the air pressure at the through hole 1070, air flows in the order of the through hole 1070, the air inlet 370, the gas flow path, and the exhaust port 371. Thus, the air at the through hole 1070 part is replenished to the exhaust port 371 and can further flow to a specific object through the exhaust port 371.

[0018] The pants device 10 further includes a first U-shaped edge portion 1071, and the through-hole 1070 is provided in the first U-shaped edge portion 1071. The urine cover 107 avoids a part of the urine cover 107 (i.e., the first U-shaped edge portion 1071) from shielding the air inlet 370 through the through-hole 1070. Therefore, in this embodiment, the through-hole 1070 can also be called an outlet. The through-hole 1070, the air inlet 370, the left flow path 372, and the exhaust port 371 communicate in sequence to form an air flow path, and the through-hole 1070, the air inlet 370, the right flow path 373, and the exhaust port 371 also communicate in sequence to form another air flow path.

The negative pressure source includes a motor and an impeller. The wheels are located below the host computer and move the host computer. The impeller rotates driven by the motor and generates a suction airflow to suck the excrement collected in the excrement container 40. Due to the suction effect of the negative pressure source, the air pressure in the excrement container 40 becomes smaller than the air pressure outside the excrement collection assembly, and the excrement in the excrement container 40 is sucked. Specifically, when in use, the pants device 10 is worn on the human body. Due to the suction effect of the negative pressure source, the air pressure at the exhaust port 371 becomes smaller than the air pressures at the intake port 370 and the through port 1070. Viewed from another angle, due to the suction effect of the negative pressure source, the air pressure in the excrement container 40 becomes smaller than the air pressure outside the excrement collection assembly (that is, the air pressure in the excrement container 40 is negative pressure relative to the air pressure outside the excrement collection assembly). Due to the existence of the pressure difference, the air outside the excrement collection assembly flows in the order of the intake port 370, the gas flow path, and the exhaust port 371, is replenished to the excrement container 40, and promotes the more complete suction of the excrement collected in the excrement container 40. More specifically, due to the suction of the negative pressure source of the host computer, the air pressure in the excrement container 40 becomes smaller than the air pressure outside the excrement collection assembly, and the air outside the excrement collection assembly flows in the order of the through port 1070, the protective net 109, the intake port 370, the gas flow path, and the exhaust port 371 to replenish the excrement container 40.During use, the pants device 10 is worn on the human body. After the human body excretes, the negative pressure source sucks. Under the suction action of the negative pressure source, the air pressure in the excrement container 40 becomes smaller than the air pressure outside the excrement collection assembly, so that a part of the air outside the excrement collection assembly flows in the order of the through hole 1070, the protective net 109, the left half 3700 of the air inlet 370, the left flow path 372, and the exhaust port 371, and is replenished into the excrement container 40. Another part of the air outside the excrement collection assembly flows in the order of the through hole 1070, the protective net 109, the right half 3701 of the air inlet 370, the right flow path 373, and the exhaust port 371, and is replenished into the excrement container 40.

[0034] The working head 11 further includes a dirt discharge interface 190 and an adaptation connection interface 191. The dirt discharge interface 190 is connected to the dirt suction pipeline. Under the suction action of the negative pressure source, the excrement collected in the excrement container 40 passes through the dirt discharge port 43, the dirt discharge interface 190, and the dirt suction pipeline in sequence and is sucked by the upper computer, and is stored in the dirt bucket of the upper computer. The upper computer sends warm air to the working head 11 via the warm air pipeline and blows it towards the lower body of the human body via the dry exhaust port 371 to dry the lower body of the human body. The upper computer sends clean water to the working head 11 via the water supply pipeline and sprays it via the front nozzle 160, the rear nozzle 162, etc.
