[0014] Working principle: During the cleaning process, first, the storage tank in the temperature control component heats water through the water heater, and the hot water is transported to the sprinkler head through the hot water pipe. The manual control component in the temperature control component can manually adjust the water intake of hot water. Turning the handle drives the worm and worm gear to rotate, and drives the adjustment plate to rotate on the outer wall of the baffle to ensure precise control of the water temperature and meet the patient's comfort needs. At the same time, the display in the temperature control component displays the water temperature in real time, and the controller makes corresponding adjustments according to the needs of the nursing staff to ensure that the water temperature is within the appropriate range.

[0015] The filter assembly inside the cleaning tank is responsible for purifying the wastewater generated during the cleaning process. The wastewater first flows into the wastewater tank, and the large particles are removed through filter one. The wastewater passes through filter two and the activated carbon plate to further remove harmful substances and odors, thereby realizing the recycling and reuse of the wastewater. The water pump draws the filtered and purified wastewater from the bottom of the wastewater tank through pump pipe two, and transports it to the inside of the cold water tank to realize the recycling of water.

[0016] After cleaning is completed, the disinfection component disinfects the inside of the cleaning box through the nozzle. The disinfectant in the cleaning liquid tank is drawn into the connecting pipe through the delivery pump 2, and then diverted to multiple nozzles for atomization spraying, ensuring that every corner is covered with disinfectant, reducing the risk of bacterial growth and cross infection, and maintaining the hygiene of the cleaning box.

[0017] A collection box is provided at the top of the cleaning box, and multiple leak holes are provided inside the box to collect the disinfectant and guide it to the collection bucket, and then discharge it from the cleaning box through the outlet pipe to ensure the cleanliness of the equipment and the tidiness of the operating environment. At the same time, a wastewater tank is designed at the bottom of the cleaning box. The wastewater tank is equipped with a multi-layer filtration structure and an activated carbon layer to ensure the effective treatment and purification of wastewater, thereby reducing the risk of environmental pollution and improving the overall functionality and safety of the cleaning equipment.

[0018] The present invention provides a cleaning device for nursing patients in the critical care department. It has the following beneficial effects:

[0019] 1. The present invention achieves precise control of water temperature through the coordination between the internal structures of the temperature control component and the manual control component, while facilitating manual control of the amount of hot water added, thereby solving the problems of patient discomfort and low nursing efficiency caused by uneven water temperature or inconvenient water addition during the nursing process. Specifically, the temperature control component is equipped with a highly sensitive temperature sensor and a manual regulating valve, which can monitor the water temperature in real time and adjust it immediately according to nursing needs, ensuring that each cleaning is performed within a comfortable temperature range acceptable to the patient.

[0020] 2.

The filter assembly adopts a multi-layer filtration system, including a primary filter screen and an activated carbon layer, which can effectively remove particulate matter and harmful substances in wastewater.

[0021] 3. The present invention achieves the effect of simple disinfection of the interior of the cleaning box through the coordination between the disinfection component and the internal structure of the collection component, thereby solving the problems of bacterial growth and cross-infection risks caused by frequent use of cleaning equipment. The disinfection component adopts an efficient spray disinfectant distribution system, which can automatically spray and disinfect the interior of the cleaning box after cleaning is completed.
