Description

Technical Field

[0001] This utility model belongs to the field of automatic urine and feces treatment technology, specifically relating to an automatic urine and feces treatment control device that can be used by multiple people. Background Technology

[0002] To facilitate toileting care for disabled elderly residents, modern nursing homes have installed toileting assistance devices on their beds. These devices typically consist of a main unit, a collection container, and a special mattress. One set is installed on each disabled resident's bed, primarily for collecting and storing their daily waste. This system uses a vacuum collection mechanism to centrally collect and store waste, adding clean water and emptying the wastewater in the morning and evening. This effectively solves the problem of toileting care for disabled elderly residents and reduces environmental pollution.

[0003] However, existing automatic waste disposal devices typically have one main unit that can only connect to one waste collection head, and one waste collection head can only meet the needs of one user. The main unit only works when the user defecates, resulting in long idle time for the main unit, wasted resources, and increased operating costs. Therefore, there is an urgent need for an automatic waste disposal control device that can be used by multiple people to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide an automatic waste disposal control device that can be used by multiple people, so as to solve the problem mentioned in the background art that the existing automatic waste disposal devices usually only support one waste collection head connected to one host, resulting in long idle time of the host and waste of resources.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic defecation and urination control device that can be used by multiple people, comprising an expander shell, a waste collection head connector, a valve assembly, a waste collection device connector, a circuit board, and a water and gas pipeline tee assembly. The waste collection head connector is fixedly connected to the inner walls of both the left and right ends of the expander shell. The valve assembly is fixedly connected to the side of the waste collection head connector closer to the middle. The waste collection device connector is fixedly connected to the inner wall of the rear end of the expander shell. A circuit board is provided at the rear end of the expander shell. A control line plug is fixedly connected to both the front and rear ends of the circuit board. The control line plug inside is electrically connected to the waste collection head connector. The water and gas pipeline tee assembly is fixedly connected to the inner wall of the bottom of the expander shell.

[0006] Preferably, the valve assembly includes a drain pipe valve, two vent pipe valves, three drain pipe valves, and a valve assembly bracket. The top of the valve assembly bracket is fixedly connected to the drain pipe valve and the two vent pipe valves, with the two vent pipe valves located at the left and right ends of the drain pipe valve, respectively. The bottom of the valve assembly bracket is fixedly connected to the three drain pipe valves.

[0007] Preferably, the sewage pipe valve is fixedly connected in the middle of the sewage collection head connector, and the sewage collection head connector is fixedly connected to two exhaust pipe valves and three drain pipe valves through five connecting pipes.

[0008] Preferably, the front side of the urine and feces collection device connector is fixedly connected to a sewage pipe tee, and both ends of the sewage pipe tee are fixedly connected to one end of a sewage pipe, while the other end of the sewage pipe is fixedly connected to the sewage pipe valve of the valve assembly.

[0009] Preferably, pipe seals are provided at the connection points between the sewage pipe tee and the urine and feces collection device connector, and at the connection points between the sewage pipe tee and the sewage pipe.

[0013] 1. This automatic waste disposal control device, which can be used by multiple users, is equipped with multi-level communication modules, dynamic resource allocation, and fault isolation mechanisms. The microcontroller communicates with the host control via serial communication and interacts with the host panel via serial communication. The microcontroller is connected to the 485 bus, which enables the host resources (water pump, air pump, sewage recovery) to be dynamically allocated according to the waste / urine sensor signals of the waste collection head, ensuring independent control. When any waste collection head or microcontroller fails, the extender automatically blocks the abnormal signal and switches to the backup link.

[0033] 2. Microcontroller 1 / 2 performs a self-test to confirm that the sensors and relays are in normal condition.

[0034] II. Operational Phase:

[0035] 1. When the stool collection head triggers defecation:

[0036] a. When microcontroller one detects a signal from the feces sensor, it sends the signal to microcontroller three via the 485 bus.

[0037] b. Microcontroller 3 requests Microcontroller 2 to close the solenoid valve of toilet head 2 via the 485 bus, and Microcontroller 1 opens the clean water valve, gas valve, and sewage valve of toilet head 1.

[0038] c. The microcontroller disconnects the relay of toilet head two and closes the relay of toilet head one;

[0039] d. The main unit starts the water pump, and clean water is sprayed out through the toilet head, while sewage flows back to the sewage tank through the three-way valve;

[0041] III. Control Methods:

[0042] 1. Signal acquisition stage: The microcontrollers of the extender acquire the sensor signals of the collector heads in real time and synchronize them to the microcontroller of the extender via the 485 bus.

[0043] 2. Logic Judgment Stage: The microcontroller determines the priority based on the sensor signals and the current status of the host, such as flushing taking precedence over drying the stool, and decides on the number of the stool collection head to be connected to the host.

[0044] 3. Execution Control Phase:

[0045] a) The microcontroller 3 judges the information returned by the microcontroller 1 / 2 through the 485 bus and switches the solenoid valve group of clean water / gas circuit and electric ball valve sewage circuit inside the expander to the target toilet head pipeline.

[0046] b) Microcontroller 3 sends relay opening and closing commands to microcontrollers 1 and 2 via the 485 bus;

[0048] IV. System Architecture

[0049] 1. Multi-level communication module: Microcontroller 3 communicates with the host main controller through serial communication port 1, interacts with the host panel through serial communication port 2, and connects to microcontroller 1 / 2 via 485 bus.

[0050] 2. Dynamic resource allocation: The main unit's water pump, air pump, and sewage recovery are dynamically allocated based on the feces / urine sensor signals from the collection head, ensuring independent control.

[0051] 3. Fault isolation mechanism: When any collector head or microcontroller fails, the extender automatically blocks the abnormal signal and switches to the backup link.
