Technical Field

[0001] This utility model belongs to the field of nursing bed technology, and in particular relates to an intelligent body-washing device for nursing beds. Background Technology

[0002] Nursing beds primarily address the nursing needs of patients, the elderly, or long-term bedridden patients. They provide a more efficient and comfortable nursing experience through the design and improvement of bed structure, function, and intelligent systems. This field encompasses innovative technologies such as bed structure optimization, bed adjustment systems, intelligent control, and auxiliary nursing functions (e.g., automatic turning, cleaning, and position monitoring) to reduce the workload of caregivers and improve patient comfort and quality of care. With the advent of an aging society, the nursing needs of the elderly are increasing, especially the daily care of bedridden elderly and patients. Therefore, the cleanliness of nursing beds is particularly important.

[0003] Nursing beds often accumulate food scraps, hair, and other impurities during use. Traditional methods of cleaning nursing beds often rely on manual assistance, which is not only inefficient and unhygienic, but also puts a heavy burden on caregivers. The process often requires moving the patient, which may cause secondary harm to the elderly or critically ill patients. Therefore, it is particularly important to develop an intelligent cleaning device that can efficiently and automatically clean nursing beds.

[0004] To address these issues, we propose an intelligent personal hygiene device for nursing beds. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that it cannot automatically and efficiently clean impurities and debris on nursing beds, and to propose an intelligent body cleaning device for nursing beds.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart personal hygiene device for a nursing bed includes a nursing bed body. Two sliding grooves are formed on the inner wall of the nursing bed body. A threaded rod is rotatably connected to the inner wall of each sliding groove. Two servo motors are arranged on the outer side of the nursing bed body. The power output end of each servo motor is fixedly connected to the right end of the threaded rod. A carrying slide is threadedly connected to the outer surface of each threaded rod. A carrying plate is fixedly connected to the upper surface of the two carrying slides. A controller body is fixedly connected to the upper surface of the carrying plate.

The end of the connecting pipe away from the vacuum negative pressure pump is fixedly connected to a storage tank. The outer surface of the storage tank is slidably connected to the inside of the second elliptical hole. The bottom surface of the storage tank is fixedly connected to a discharge pipe.

[0008] Preferably, each of the servo motors has an L-shaped plate fixedly connected to its outer surface, and the left side of each L-shaped plate is fixedly connected to the right side of the nursing bed body.

[0009] Preferably, a fixing frame is fixedly connected to the outer surface of the controller body, and the bottom surface of the fixing frame is fixedly connected to the upper surface of the carrier plate.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] By setting up a controller body, servo motor, slide rail, threaded rod, nursing bed body, cargo slide frame and cargo plate, the cargo plate and cargo slide frame can be driven to move left and right along the inside of the slide rail. The controller body controls the servo motor to work. The servo motor works under the support of the slide rail and drives the threaded rod to rotate. The rotation of the threaded rod in turn drives the cargo slide frame and cargo plate to move left and right along the inside of the slide rail.

[0015] By incorporating a rotary motor, lead screw, moving groove, moving block, vacuum negative pressure pump, inlet, connecting pipe, storage tank, discharge pipe, first elliptical hole, and second elliptical hole, the device can drive the moving block, vacuum negative pressure pump, and inlet to slide back and forth along the interior of the moving groove. The vacuum negative pressure pump generates negative pressure, which draws food debris, hair, or other impurities from the surface of the nursing bed into the pump through the inlet. These impurities are then transported to the storage tank through the connecting pipe. This device automatically cleans impurities from the surface of the nursing bed, improving its effectiveness and avoiding the need for manual cleaning, which requires moving the patient during cleaning and could cause secondary injury, thus reducing the device's overall efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5A smart personal hygiene device for a nursing bed includes a nursing bed body 1. The inner wall of the nursing bed body 1 has two sliding grooves 4. Each sliding groove 4 has a threaded rod 5 rotatably connected to its inner wall. Each threaded rod 5 has a bearing 23 fixedly connected to its outer surface. The outer surface of each bearing 23 is fixedly connected to the inner wall of the sliding groove 4. The bearing 23 can reinforce the threaded rod 5 and prevent the threaded rod 5 from fluctuating during use.

[0024] Two servo motors 2 are installed on the outer side of the main body 1 of the nursing bed. Each servo motor 2 has an L-shaped plate 3 fixedly connected to its outer surface. The left side of each L-shaped plate 3 is fixedly connected to the right side of the main body 1 of the nursing bed. The L-shaped plate 3 can be used to fix the servo motor 2 and prevent the servo motor 2 from shaking during use.

[0025] The output end of each servo motor 2 is fixedly connected to the right end of the threaded rod 5. The outer surface of each threaded rod 5 is threadedly connected to a load-bearing sliding frame 9. The upper surfaces of the two load-bearing sliding frames 9 are fixedly connected to a load plate 6. The upper surface of the load plate 6 is fixedly connected to the controller body 7. The outer surface of the controller body 7 is fixedly connected to a fixing frame 8. The bottom surface of the fixing frame 8 is fixedly connected to the upper surface of the load plate 6. The fixing frame 8 can be used to reinforce the controller body 7 and prevent the controller body 7 from shaking during use. The controller consists of two parts: hardware and software. The hardware mainly includes a central processing unit (CPU) for calculation, an input / output (I / O) interface for connecting sensors and actuators, a memory for storing programs and data, as well as a power supply and communication module. The software encompasses control algorithms, real-time operating systems such as RTOS, and human-machine interfaces, collectively ensuring precise and efficient system control. It is widely used in industrial automation, smart homes, automotive electronics, and other fields. A controller is a core device that regulates system operation by processing input signals in real time and generating control commands. Its working principle can be summarized as follows: First, it acquires signals from sensors or external inputs such as temperature and speed, compares them with preset target values ​​to calculate the deviation; then, it uses built-in algorithms such as PID control and logical judgment to analyze the deviation and generate adjustment commands; finally, it drives actuators such as motors and valves through the output interface to adjust the system state, while continuously monitoring the effect through closed-loop feedback to achieve dynamic stability. The controller enables control of the electrical components in this technical solution.

[0026] The upper surface of the carrying plate 6 is provided with a first elliptical hole 10 and a second elliptical hole 11. The bottom surface of the carrying plate 6 is provided with a moving groove 15. The inner wall of the moving groove 15 is rotatably connected to a lead screw 16. A rotary motor 17 is provided on the outer side of the carrying plate 6. The output end of the rotary motor 17 is fixedly connected to the end of the lead screw 16 near the controller body 7. The outer surface of the lead screw 16 is threaded with a moving block 21. The bottom surface of the moving block 21 is fixedly connected to a vacuum negative pressure pump 19. The input end of the vacuum negative pressure pump 19 is fixedly connected to a feed inlet 20. The output end of the vacuum negative pressure pump 19 is fixedly connected to a connecting pipe 12. The outer surface of the connecting pipe 12 is fixedly connected to a fixing ring 14. The bottom end of the fixing ring 14 is fixedly connected to the upper surface of the storage box 13. The fixing ring 14 can be used to reinforce the connection between the connecting pipe 12 and the storage box 13 to prevent the connection between the storage box 13 and the connecting pipe 12 from breaking, which would affect the stability of the device.

[0027] The end of the connecting pipe 12 away from the vacuum negative pressure pump 19 is fixedly connected to the storage box 13. The outer surface of the storage box 13 is slidably connected to the inside of the second elliptical hole 11. The bottom surface of the storage box 13 is fixedly connected to the discharge pipe 22. The outer surface of the rotary motor 17 is fixedly connected to the connecting plate 18. The upper surface of the connecting plate 18 is fixedly connected to the bottom surface of the carrying plate 6. The connecting plate 18 can be used to fix the rotary motor 17 and prevent the rotary motor 17 from shaking during use.

[0028] The working principle of this utility model is as follows: In use, the servo motor 2, controller body 7, vacuum negative pressure pump 19, and rotary motor 17 are first connected to the power supply. When medical staff need to clean the nursing bed, they use the controller body 7 to control the servo motor 2. The two servo motors 2, supported by the slide rail 4, drive the threaded rod 5 to rotate. Since the threaded rod 5 is threadedly connected to the carrying slide frame 9, the rotation of the threaded rod 5 drives the carrying slide frame 9, the carrying plate 6 fixed by the two carrying slide frames 9, and the cleaning structure fixed below the carrying plate 6 to slide left and right along the inside of the slide rail 4. As the cleaning structure slides left and right along the inside of the slide rail 4... The servo motor 2 controls the rotary motor 17 to operate. The rotary motor 17, supported by the moving groove 15, drives the lead screw 16 to rotate. Since the lead screw 16 is threadedly connected to the moving block 21, the rotation of the lead screw 16 causes the moving block 21 to slide back and forth along the interior of the moving groove 15. During this sliding motion, the vacuum negative pressure pump 19, the inlet 20, the connecting pipe 12, the storage tank 13, and the discharge pipe 22 slide back and forth along the interior of the carrying plate 6. Specifically, the connecting pipe 12 slides back and forth along the interior of the first elliptical hole 10, and during this sliding motion, the storage tank 13 and the discharge pipe 22 slide back and forth along the interior of the second elliptical hole 11. During the back-and-forth sliding process of the negative pressure pump 19, the controller body 7 controls the vacuum negative pressure pump 19 to work. The vacuum negative pressure pump 19 creates a negative pressure environment by reducing the air pressure inside the pump body. That is, the vacuum negative pressure pump 19 generates negative pressure. Since the feed inlet 20 is fixedly connected to the vacuum negative pressure pump 19, and the bottom of the feed inlet 20 is in contact with the surface of the nursing bed, the negative pressure generated by the vacuum negative pressure pump 19 allows impurities, food scraps, or hair fragments on the surface of the nursing bed to be transported to the inside of the storage box 13 through the connecting pipe 12 under the adsorption of the vacuum negative pressure pump 19. The moving block 21 moves back and forth along the inside of the moving groove 15, driving the carrying plate 6 and the carrying material. The cleaning structure, consisting of a lowered plate 6 and other components, moves back and forth to clean the nursing bed. A servo motor 2, supported by a slide rail 4, drives a threaded rod 5 to rotate. This rotation, in turn, moves the sliding frame 9, the carrying plate 6, and the cleaning structure fixedly connected to the carrying plate 6 left and right, thus moving the nursing bed body 1 back and forth. This device enables autonomous and automatic cleaning of the nursing bed body 1 in both left-right and back-and-forth motions, improving its cleaning efficiency. After cleaning, impurities are discharged through a valve on the discharge pipe 22. This device eliminates the need to move the patient; it automatically cleans the nursing bed body 1 through negative pressure adsorption, further enhancing its effectiveness.
