[0016] like Figures 1-6 As shown, this embodiment of the invention provides a hospital bed with an automatic cleaning function, including a main bed board 2 and two cleaning mechanisms 1. The center of the front and rear ends of the main bed board 2 is provided with trapezoidal grooves 5. An extension block 10 is fixedly provided at the front and rear ends of the main bed board 2 near the cleaning mechanism 1. An adjustment motor 9 is fixedly provided inside the two extension blocks 10. A threaded rod 6 is fixedly provided at the output end of the two adjustment motors 9. A trapezoidal slider 8 is threadedly sleeved on the body of the two threaded rods 6. A fixing frame 7 is fixedly provided at the opposite ends of the two trapezoidal sliders 8. The cleaning mechanism 1 includes a protective shell 101. A processing hole 108 is provided at the rear end of the upper surface of the protective shell 101. An upper storage cavity 115 is fixedly provided on the upper surface of the protective shell 101 above the processing hole 108. A cleaning water tank 113 is fixedly provided at the upper end of the upper storage cavity 115. A lower storage cavity 109 is fixedly provided inside the protective shell 101 below the processing hole 108. A dual-axis motor 107 is fixedly provided at the center of the top surface inside the protective shell 101. Two synchronous pulleys 106 are fixedly connected to the two output ends of the dual-axis motor 107. Rotary shafts 102 are rotatably provided inside the protective shell 101 at the front end and the rear end. A synchronous pulley 103 is fixedly sleeved in the middle of the shaft of the two rotating shafts 102. A synchronous belt 105 is provided between the synchronous pulley 103 and the synchronous pulley 106. A cleaning cotton 104 is fixedly provided on the outer surface of the synchronous belt 105.

[0017] Two spring telescopic rods 114 are fixedly installed at the rear end of the top surface inside the upper storage cavity 115. A pressure plate 110 is fixedly installed between the lower ends of the two spring telescopic rods 114. A micro-controlled water pump 112 is connected to the front end of the top surface inside the upper storage cavity 115 via a pipe. A branch pipe 111 is fixedly installed at the lower output end of the micro-controlled water pump 112. Support legs 4 are fixedly installed at the four corners of the lower end face of the bed board 2. A headboard 3 is fixedly installed at the end of the bed board 2 away from the cleaning mechanism 1. The internal cavity of the extension block 10 communicates with the trapezoidal slide 5. The trapezoidal slider 8 is slidably installed inside the trapezoidal slide 5. The end of the threaded rod 6 away from the adjusting motor 9 is rotatably installed inside the trapezoidal slide 5. The two cleaning mechanisms 1 are located at the upper and lower ends of the bed board 2, respectively. The two fixing brackets 7 are fixedly installed at the front and rear ends of the protective shell 101 by bolts. The upper end of the cleaning water tank 113 has a water inlet hole, and the internal thread of the water inlet hole is fitted with a sealing plug. Water outlet pipes are fixedly connected to one side of both the upper storage chamber 115 and the lower storage chamber 109. The input end of the micro-controlled water pump 112 extends through to the interior of the cleaning water tank 113. Spray nozzles are fixedly installed at the lower ends of the two branch pipes 111, and the nozzle nozzles are located at the cleaning cotton 104.

[0018] A dual-axis motor 107 drives a synchronous belt 105 in cyclical motion, causing the cleaning cotton 104 to contact the bed surface for mechanized wiping and cleaning. The cleaning mechanism 1, driven by an adjusting motor 9, moves along a trapezoidal slide 5, covering the upper and lower surfaces of the bed board 2 to ensure thorough cleaning. The continuous movement of the synchronous belt 105 and the cleaning cotton 104 is several times more efficient than manual wiping. The cyclical use of the cleaning cotton 104 removes dirt in real time, preventing secondary contamination. A micro-controlled water pump 112 draws disinfectant from the cleaning water tank 113 and sprays it evenly onto the surface of the cleaning cotton 104 through a nozzle on a branch pipe 111. The sprayed disinfectant, combined with the wiping action of the cleaning cotton 104, simultaneously completes cleaning and disinfection. This combination of physical wiping and chemical disinfection effectively kills pathogens and reduces the risk of cross-infection. The metered spraying by the micro-controlled water pump 112 avoids liquid waste and reduces the pressure on hospital wastewater treatment.

[0019] The pressure plate 110, under the elastic force of the spring telescopic rod 114, applies pressure to the soiled cleaning cotton 104, scraping off the adsorbed dirt and achieving self-cleaning of the cleaning cotton 104. The scraped dirt falls into the lower storage chamber 109 or the upper storage chamber 115 by gravity, and is then discharged through the drain pipe. The self-cleaning mechanism reduces the replacement frequency of the cleaning cotton 104, lowering maintenance costs. Centralized treatment of dirt avoids direct contact with contaminants by operators, improving cleaning safety.

[0020] The adjusting motor 9 drives the threaded rod 6 to rotate, which in turn moves the trapezoidal slider 8 along the trapezoidal groove 5, enabling the cleaning mechanism 1 to automatically reciprocate. The upper and lower cleaning mechanisms 1 operate synchronously, simultaneously cleaning the upper and lower surfaces of the bed board 2. The cleaning process can be completed without manual intervention, saving medical staff time. The cleaning mechanism 1 is detachably connected to the bed frame via a fixing frame 7, facilitating maintenance or upgrades. The upper storage cavity 115 collects the dirt scraped off by the upper cleaning mechanism 1, while the lower storage cavity 109 collects the dirt from the lower layer, making operation simple and convenient. An external collection device is connected via a water outlet pipe for closed-loop discharge of waste.

[0021] Working principle: This device is modular. The cleaning mechanism 1 is connected to the fixed frame 7 by bolts, which makes disassembly quick and easy. The two cleaning mechanisms 1 clean the upper and lower surfaces of the bed board 2 respectively. When cleaning is needed, after removing the relevant bed sheet and keeping the bed board 2, the two adjusting motors 9 are started. The two adjusting motors 9 are controlled to rotate synchronously by the set controller, which drives the threaded rod 6 to rotate. The rotation of the threaded rod 6 drives the trapezoidal slider 8 to slide in the trapezoidal groove 5, which can drive the fixed frame 7 and the connected cleaning mechanism 1 from the foot of the bed to the head of the bed. The back-and-forth movement of the cleaning mechanism 1 from the head to the foot of the bed is realized by the motor controller. During this process, the dual-axis motor 107 and the micro-controlled water pump 112 are started. After the dual-axis motor 107 starts, it drives the second synchronous pulley 106 to rotate, realizing the transmission of the synchronous belt 105. During the transmission of the synchronous belt 105, the cleaning cotton 104 contacts the bed board 2 for cleaning. After the micro-controlled water pump 112 starts, it can spray the disinfectant or cleaning water in the cleaning water tank 113 through the nozzle of the branch pipe 111 onto the surface of the cleaning cotton 104. At the same time, under the elastic force of the spring telescopic rod 114, the pressure of the pressure plate 110 pressing down on the synchronous belt 105 is applied. The cleaning cotton 104 is squeezed and, after coming into contact with the bed board 2 and becoming dirty, moves to the pressure plate 110. The pressure of the pressure plate 110 can scrape off the dirt. The dirt from the upper cleaning mechanism 1 falls into the lower storage cavity 109, and the dirt from the lower cleaning mechanism 1 falls into the upper storage cavity 115. Both can be discharged through the water outlet pipe. The cleaned cleaning cotton 104 will also be sprayed by the nozzle for further cleaning and moisturizing. The whole process is automated, simple to operate, and convenient to use.

[0022] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
