Description

Technical Field

[0001] The present invention relates to the technical field of nursing beds, in particular to an intelligent nursing bed with an automatic rapid sterilization function. Background Art

[0002] In order to take care of patients with limited mobility, hospitals usually set up nursing beds in wards to assist with patients' treatment and rehabilitation. Currently, nursing beds come in a variety of forms and can generally be divided into electric or manual nursing beds, designed according to the patient's bedridden lifestyle and treatment needs.

[0003] However, in existing general wards, there is usually more than one patient receiving hospitalization in the same ward. Different patients have different admission times and treatment cycles. The viruses they carry and the infectiousness of the patients to others are different. This mixed treatment will inevitably cause cross-infection between patients, and even cause patients whose conditions have been alleviated to be reinfected by severe patients, aggravating their conditions. In order to solve the above problems, current nursing beds usually adopt a method similar to the patent "CN105030448B A method for preparing a nursing bed with sterilization function (published on 2018.0 6.01)", "CN101632615B intelligent nursing bed (publication date 2011.08.10)", but the above technical solutions often have the following problems in actual use: first, it is impossible to remove stains and other substances on the surface of the nursing bed, and the dead bodies of bacteria and microorganisms cannot be processed in time. After a period of time, the bacteria are very likely to reproduce again, causing damage to the patient's health; second, the current nursing beds cannot remove urine scale during the process of processing the patient's urine, so that the urine storage area is often blocked, odor is scattered, and bacteria breed. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent nursing bed with an automatic rapid sterilization function to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an intelligent nursing bed with automatic rapid sterilization function, the intelligent nursing bed comprises a bed frame and a support seat, the bed frame is arranged above the support seat, and footboards and pillows are arranged on both sides of the bed frame, the footboards and pillows are aligned, and two groups of cleaning mechanisms are arranged on the other two sides of the bed frame, the two groups of cleaning mechanisms are aligned, and the bed frame is cleaned by the cleaning mechanisms, a liquid storage tank is arranged on the side of the pillow away from the footboard, and two groups of liquid storage chambers are arranged inside the liquid storage tank, one group of the liquid storage chambers is provided with disinfectant, and the other group of the liquid storage chambers is provided with clean water, a working tank is arranged at the upper end of the liquid storage tank, and a second liquid pump and a spray rack are arranged inside the working tank, one end of the second liquid pump is connected to the two groups of liquid storage chambers through a three-way pipe, and two groups of valves are arranged on the three-way pipe, and the other end of the second liquid pump is connected to the spray rack through a hose, and the spray rack has lifting and rotating functions.

[0006] The support seat is the installation base of the present invention, the bed frame is the nursing base of the present invention, the spray frame is arranged in the working groove through the electric lifting rod and the electric turntable, the surface of the pillow pad is waterproof material, when the patient leaves the bed frame, the spray frame is controlled to move to the top of the pillow pad through the electric lifting rod and the electric turntable, and then the second pumping pump and the three-way pipe are opened to extend into a group of valves in the disinfectant, and the disinfectant in the liquid storage chamber is sprayed onto the top of the pillow pad through the second pumping pump. Since the pillow pad has a slope, the disinfectant will flow into the bed frame along the pillow pad to sterilize and disinfect the pillow pad and the bed frame. When the disinfection is completed, the three-way pipe is closed to extend into the disinfectant. A group of valves in the clean water are opened to extend into the clean water, and then the clean water in the liquid storage chamber is sprayed onto the top of the pillow pad to achieve the purpose of removing residual disinfectant. The present invention is also provided with a cleaning mechanism, which is controlled by a linear motor to move on the side of the bed frame to avoid the disinfectant and the clean water from flowing down from the pillow pad. The flushing force is reduced, causing the stains to be attached to the bed frame and difficult to clean.

[0007] Furthermore, a protective component is provided inside the liquid storage tank, and the protective component includes a protective frame, and an aspirator, a detection chamber, an air outlet groove and a pH meter are provided inside the protective frame. One end of the detection chamber is connected to the aspirator, and the other end of the detection chamber is connected to the air outlet groove. The interior of the detection chamber is filled with a fluid medium, and the detection end of the pH meter extends into the detection chamber.

[0008] Since the disinfectant is volatile, for example, when the disinfectant is sodium hypochlorite, chlorine will be volatilized, so the present invention is provided with a protective component. When the patient lies on the bed frame, the gas in the working tank can be sucked into the detection chamber by the aspirator. The fluid medium filled in the detection chamber of the present invention selects a substance similar to the aqueous solution. At this time, the pH value of the fluid medium filled in the detection chamber will change. The chlorine content in the working tank is indirectly judged by the degree of change of the pH value, so as to prevent the gas volatilized by the disinfectant from leaking from the three-way pipe or various connection gaps when the patient lies on the bed frame, and the nursing staff cannot react in time.

[0009] Furthermore, an isolation membrane is provided inside the detection chamber, which divides the detection chamber into two areas. The area close to the air aspirator and the air outlet groove is filled with an aqueous solution, and the area far from the air aspirator and the air outlet groove is filled with calcium oxide. The isolation membrane is made of a corrosive material, and the air outlet groove is a whistle-shaped structure.

[0010] In order to avoid the failure of the pH meter and the failure of the early warning, the present invention is provided with an isolation membrane in the detection room. Under normal circumstances, the gas inhaled by the aspirator should not contain chlorine. If at a certain moment, the volatilized gas of the disinfectant leaks from the liquid storage chamber, as the gas inhaled by the aspirator increases, the acidity of the aqueous solution near the aspirator and the air outlet groove area will also increase accordingly. The isolation membrane provided in the present invention is a material that is easily corroded by acid. At the same time, the aspirator inhales external gas at a slow speed. Under normal circumstances, the flow rate of this group of gases is not enough to make the air outlet groove make a sound, but when the acidity of the aqueous solution reaches a certain level, the isolation membrane will rupture and make the aqueous solution contact with calcium oxide. At this time, calcium oxide reacts with the aqueous solution to release heat and steam. In this case, the gas coming out of the air outlet groove will increase dramatically, so that the air outlet groove makes a sound, alerting nearby nursing staff to check. Through the above technical scheme, the purpose of redundant protection can be achieved, and the safety of patients is further guaranteed.

[0011] Furthermore, baffle bars are provided on the sides of the bed frame and the pillow, a liquid leakage groove is provided in the middle position of the bed frame, a first waste liquid chamber and a second waste liquid chamber are provided inside the support seat, a reversing groove is provided between the first waste liquid chamber and the second waste liquid chamber, the reversing groove is aligned with the liquid leakage groove, a reversing plate is provided inside the reversing groove, and a reversing motor is provided outside the reversing groove, and the reversing motor drives the reversing plate to rotate in the reversing groove.

[0012] The present invention prevents disinfectant and water from flowing around by means of a baffle, and collects the waste liquid and urine after disinfection through the first waste liquid chamber and the second waste liquid chamber. That is, when the patient lies on the bed frame, the reversing plate is driven to rotate by the reversing motor so that the inclined surface of the reversing plate faces the second waste liquid chamber. At this time, the patient's urine can be discharged into the second waste liquid chamber through the urinary catheter. When the patient leaves the bed frame and the nursing bed needs to be sterilized and cleaned, the reversing plate is driven to rotate by the reversing motor so that the inclined surface of the reversing plate faces the first waste liquid chamber. At this time, the disinfectant and clean water in the liquid storage tank will enter the first waste liquid chamber along the reversing groove and the leakage groove after cleaning the bed frame and the pillow, thereby achieving the purpose of recycling and reuse.

[0013] Furthermore, a first liquid pump is provided inside the support seat, a liquid inlet end of the first liquid pump is connected to the first waste liquid chamber via a first guide groove, a liquid outlet end of the first liquid pump is connected to the second waste liquid chamber via a second guide groove, a descaling component is provided inside the second waste liquid chamber, a paddle is provided inside the second guide groove, and the paddle is connected to the descaling component.

[0014] Since the patient's urine usually contains urine scale, the present invention is provided with a first liquid pump. When the second waste liquid chamber needs to be cleaned, it is only necessary to turn on the first liquid pump. The waste disinfectant in the first waste liquid chamber can be sent into the second waste liquid chamber along the second guide groove through the first liquid pump to clean the inside of the second waste liquid chamber. In addition, the present invention is also provided with a paddle and a descaling component. When the waste disinfectant flows through the second guide groove, the paddle will drive the descaling component to work. The descaling component can prevent the urine scale from adhering to the inner wall of the second waste liquid chamber too tightly.

[0015] Furthermore, the descaling assembly includes a rotating frame, a centrifugal brush and a telescopic spring rod, the rotating frame is connected to the paddle, the fixed end of the telescopic spring rod is arranged on the outside of the rotating frame, and the movable end of the telescopic spring rod is connected to the centrifugal brush.

[0016] Through the above technical solution, when the descaling component rotates, under the action of centrifugal force, the centrifugal brush will move away from the rotating frame and apply a set of pressures to the inner wall of the second waste liquid chamber. By controlling the liquid flow rate in the second guide groove, the pressure of the centrifugal brush on the inner wall of the second waste liquid chamber can be controlled, thereby ensuring the effect of cleaning urine scale.

[0017] Furthermore, a fan is provided on the footboard, and the cleaning mechanism includes an armrest frame and a cleaning frame, a storage slot is provided at one end of the armrest frame close to the bed frame, and the cleaning frame is arranged in the storage slot, the armrest frame and the cleaning frame are connected by a rotating shaft and a rotating motor, a ventilation slot is provided inside the cleaning frame, and fan blades and a transmission assembly are provided inside the ventilation slot, a cleaning disc and an electromagnet are provided at one end of the cleaning frame close to the bed frame, the electromagnet is provided between the cleaning disc and the transmission assembly, the cleaning disc is connected to the transmission assembly, and a magnetic block is provided at one end of the cleaning disc close to the electromagnet.

[0018] The present invention is provided with heating tubes inside the bed frame and the pillow, which can provide a comfortable environment for patients in winter on the one hand, and can accelerate the drying speed of the bed frame and the pillow after disinfection on the other hand. Finally, the present invention is also provided with a cleaning mechanism. After the disinfection of the bed frame and the pillow by the disinfectant is completed, the cleaning frame is controlled by a rotating motor to extend out of the storage slot and parallel to the footboard, and then the electromagnet is turned on to make the electromagnet generate a group of magnetic fields that repel the magnetic blocks on the cleaning disk. At this time, under the action of the magnetic field repulsion, the cleaning disk will descend and contact the bed frame, and the handrail frame and the cleaning disk are controlled to move by the linear motor, and the bed frame is cleaned and deliquified and destained by the cleaning disk.

[0019] Furthermore, the transmission assembly includes a fixed frame, a bevel gear assembly, a sleeve and a transmission rod, the sleeve is connected to the fan blades through the bevel gear assembly, the transmission rod is arranged inside the sleeve, one end of the transmission rod extends into the sleeve, the other end of the sleeve is connected to the cleaning disk, and the end of the transmission rod extending into the sleeve is provided with a compression spring.

[0020] Through the above technical scheme, the present invention is also provided with a fan. When the cleaning mechanism is working, the fan is in an open state. The airflow generated by the fan accelerates the evaporation rate of the liquid on the one hand, and drives the fan blades to rotate on the other hand. When the fan blades rotate, the sleeve and the transmission rod will rotate with the cleaning disc. The rotation of the cleaning disc can increase the stain removal effect, and it can also serve the purpose of leveling the bed frame, reducing the probability of wrinkles and the like on the bed frame, and increasing the sterilization effect through the ultraviolet sterilization lamp.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: compared with the current nursing beds, the present invention is provided with a spraying frame and a cleaning mechanism, the spraying frame is controlled to move to the top of the pillow pad by an electric lifting rod and an electric turntable, the disinfectant in the liquid storage chamber is sprayed to the top of the pillow pad by a second liquid pump, and then the pillow pad and the bed frame are sterilized and disinfected, and the cleaning mechanism is controlled to move on the side of the bed frame by a linear motor to avoid the disinfectant and clean water from flowing down from the pillow pad. The flushing force is reduced, causing the stains to be attached to the bed frame and difficult to clean. The present invention is also provided with a protective component, and the protective component has a dual alarm function, that is, the pH value in the detection room is tested by a pH meter. The chlorine content in the working tank can be indirectly judged by the degree of chlorination, so as to prevent the volatilized gas of the disinfectant from leaking from the three-way pipe or various connecting gaps when the patient is lying on the bed frame, and the nursing staff cannot react in time. When the pH meter fails and the early warning fails, the aqueous solution can contact with calcium oxide through the rupture of the isolation membrane, and then react to release heat and steam, so that the gas outlet groove makes a sound, alerting the nearby nursing staff to check. Finally, the present invention is provided with a first liquid pump and a descaling component, which removes the urine scale in the second waste liquid chamber, on the one hand to avoid the reproduction of bacteria, and on the other hand to realize the function of recycling the disinfectant.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figure 1-Figure 2 , Figure 7As shown, an intelligent nursing bed with automatic rapid sterilization function includes a bed frame 1 and a support seat 2. The bed frame 1 is arranged above the support seat 2. A footboard 3 and a pillow 4 are arranged on both sides of the bed frame 1. The footboard 3 and the pillow 4 are aligned. Two groups of cleaning mechanisms 6 are arranged on the other two sides of the bed frame 1. The two groups of cleaning mechanisms 6 are aligned. A linear motor is arranged inside one end of the bed frame 1 close to the cleaning mechanism 6. The bed frame 1 is cleaned by the cleaning mechanism 6. A liquid storage tank 5 is arranged on the side of the pillow 4 away from the footboard 3. The liquid storage tank Two groups of liquid storage chambers 51 are arranged inside 5, one group of liquid storage chambers 51 is arranged inside disinfectant, and the other group of liquid storage chambers 51 is arranged inside clean water. A working tank 54 is arranged at the upper end of the liquid storage tank 5, and a second liquid pump 52 and a spray rack 55 are arranged inside the working tank 54. One end of the second liquid pump 52 is connected to the two groups of liquid storage chambers 51 through a three-way pipe, and two groups of valves are arranged on the three-way pipe. The other end of the second liquid pump 52 is connected to the spray rack 55 through a hose, and the spray rack 55 has lifting and rotating functions.

[0038] The support base 2 is the installation base of the present invention, the bed frame 1 is the nursing base of the present invention, the spray frame 55 is arranged in the working groove 54 through the electric lifting rod and the electric turntable, the surface of the pillow 4 is made of waterproof material, when the patient leaves the bed frame 1, the spray frame 55 is moved to the top of the pillow 4 by the electric lifting rod and the electric turntable, and then the second pumping pump 52 and the three-way pipe are opened to extend into a group of valves in the disinfectant, and the disinfectant in the liquid storage chamber 51 is sprayed to the top of the pillow 4 by the second pumping pump 52. Since the pillow 4 has a slope, the disinfectant will The liquid flows along the pillow 4 onto the bed frame 1 to sterilize the pillow 4 and the bed frame 1. When the disinfection is completed, a group of valves extending from the three-way pipe into the disinfectant are closed, and a group of valves extending from the three-way pipe into the clean water are opened, so that the clean water in the liquid storage chamber 51 is sprayed onto the top of the pillow 4 to achieve the purpose of removing residual disinfectant. The present invention is also provided with a cleaning mechanism 6, which is controlled by a linear motor to move on the side of the bed frame 1 to avoid the disinfectant and the clean water from reducing the flushing force when flowing down from the pillow 4, causing the stains to adhere to the bed frame 1 and be difficult to clean.

[0039] like Figure 1-Figure 4 As shown, a protective component 53 is also provided inside the liquid storage tank 5, and the protective component 53 includes a protective frame 531. The interior of the protective frame 531 is provided with an aspirator 532, a detection chamber 533, an air outlet groove 534 and a pH meter. One end of the detection chamber 533 is connected to the aspirator 532, and the other end of the detection chamber 533 is connected to the air outlet groove 534. The interior of the detection chamber 533 is filled with a fluid medium, and the detection end of the pH meter extends into the detection chamber 533.

[0040] Since the disinfectant is volatile, for example, when the disinfectant is sodium hypochlorite, chlorine gas will be volatilized, the present invention is provided with a protective component 53. When the patient lies on the bed frame 1, the gas in the working tank 54 can be sucked into the detection chamber 533 through the aspirator 532. The fluid medium filled in the detection chamber 533 of the present invention is a substance similar to an aqueous solution. At this time, the pH value of the fluid medium filled in the detection chamber 533 will change. The chlorine content in the working tank 54 can be indirectly judged by the degree of change in the pH value, so as to prevent the gas volatilized by the disinfectant from leaking from the three-way pipe or various connection gaps when the patient lies on the bed frame 1, and the nursing staff cannot react in time.

[0041] like Figure 1-Figure 4 As shown, an isolation membrane 5331 is provided inside the detection chamber 533, and the detection chamber 533 is divided into two areas by the isolation membrane 5331. The area close to the air aspirator 532 and the air outlet groove 534 is filled with an aqueous solution, and the area away from the air aspirator 532 and the air outlet groove 534 is filled with calcium oxide. The isolation membrane 5331 is made of easily corrosive material, and the air outlet groove 534 is a whistle-shaped structure.

[0042] In order to avoid the failure of the pH meter and the failure of the early warning, the present invention is provided with an isolation membrane 5331 in the detection chamber 533. Under normal circumstances, the gas inhaled by the aspirator 532 should not contain chlorine. If at a certain moment, the volatilized gas of the disinfectant leaks from the liquid storage chamber 51, as the gas inhaled by the aspirator 532 increases, the acidity of the aqueous solution in the area near the aspirator 532 and the air outlet groove 534 will also increase accordingly. The isolation membrane 5331 provided in the present invention is a material that is easily corroded by acid. At the same time, the aspirator 532 inhales external gas at a slow speed. Under normal circumstances, the flow rate of this group of gases is not enough to make the air outlet groove 534 make a sound, but when the acidity of the aqueous solution reaches a certain level, the isolation membrane 5331 will rupture and make the aqueous solution contact with calcium oxide. At this time, the calcium oxide reacts with the aqueous solution to release heat and steam. In this case, the gas coming out of the air outlet groove 534 will increase dramatically, so that the air outlet groove 534 makes a sound, alerting nearby nursing staff to check. Through the above technical solution, the purpose of redundant protection can be achieved, and the safety of patients is further guaranteed.

[0043] like Figure 1 and Figure 5 As shown, baffles are provided on the sides of the bed frame 1 and the pillow 4, a liquid leakage groove 11 is provided at the middle position of the bed frame 1, a first waste liquid chamber 21 and a second waste liquid chamber 22 are provided inside the support seat 2, a reversing groove 25 is provided between the first waste liquid chamber 21 and the second waste liquid chamber 22, the reversing groove 25 is aligned with the liquid leakage groove 11, a reversing plate 251 is provided inside the reversing groove 25, and a reversing motor is provided outside the reversing groove 25, and the reversing plate 251 is driven to rotate in the reversing groove 25 by the reversing motor.

[0044] The present invention uses a baffle to prevent disinfectant and water from flowing around, and collects the disinfected waste liquid and urine through the first waste liquid chamber 21 and the second waste liquid chamber 22. That is, when the patient lies on the bed frame 1, the reversing motor drives the reversing plate 251 to rotate so that the inclined surface of the reversing plate 251 faces the second waste liquid chamber 22. At this time, the patient's urine can be discharged into the second waste liquid chamber 22 through the urinary catheter. When the patient leaves the bed frame 1 and the nursing bed needs to be sterilized and cleaned, the reversing motor drives the reversing plate 251 to rotate so that the inclined surface of the reversing plate 251 faces the first waste liquid chamber 21. At this time, the disinfectant and clean water in the liquid storage tank 5 will enter the first waste liquid chamber 21 along the reversing groove 25 and the leakage groove 11 after cleaning the bed frame 1 and the pillow pad 4, thereby achieving the purpose of recycling and reuse.

[0045] like Figure 1 , Figure 5 and Figure 6 As shown, a first liquid pump 24 is also provided inside the support seat 2, the liquid inlet end of the first liquid pump 24 is connected to the first waste liquid chamber 21 through a first guide groove, the liquid outlet end of the first liquid pump 24 is connected to the second waste liquid chamber 22 through a second guide groove, a descaling component 221 is provided inside the second waste liquid chamber 22, a paddle 23 is provided inside the second guide groove, and the paddle 23 is connected to the descaling component 221.

[0046] Since the patient's urine usually contains urine scale, the present invention is provided with a first liquid pump 24. When the second waste liquid chamber 22 needs to be cleaned, it is only necessary to turn on the first liquid pump 24. The waste disinfectant in the first waste liquid chamber 21 can be sent into the second waste liquid chamber 22 along the second guide groove through the first liquid pump 24 to clean the inside of the second waste liquid chamber 22. In addition, the present invention is also provided with a paddle 23 and a descaling component 221. When the waste disinfectant flows through the second guide groove, it will drive the paddle 23 to work with the descaling component 221. The descaling component 221 can prevent the urine scale from adhering to the inner wall of the second waste liquid chamber 22 too tightly.

[0047] like Figure 1 , Figure 5 and Figure 6 As shown, the descaling assembly 221 includes a rotating frame 2211, a centrifugal brush 2212 and a telescopic spring rod 2213. The rotating frame 2211 is connected to the paddle 23. The fixed end of the telescopic spring rod 2213 is arranged on the outside of the rotating frame 2211, and the movable end of the telescopic spring rod 2213 is connected to the centrifugal brush 2212.

[0048] Through the above technical solution, when the descaling component 221 rotates, under the action of centrifugal force, the centrifugal brush 2212 will move away from the rotating frame 2211 and apply a set of pressures to the inner wall of the second waste liquid chamber 22. By controlling the liquid flow rate in the second guide groove, the pressure of the centrifugal brush 2212 on the inner wall of the second waste liquid chamber 22 can be controlled, thereby ensuring the effect of cleaning urine scale.

[0049] like Figure 1 , Figure 9-12 As shown, a fan is provided on the footboard 3, and the cleaning mechanism 6 includes an armrest frame 61 and a cleaning frame 62. A storage groove is provided at one end of the armrest frame 61 close to the bed frame 1, and the cleaning frame 62 is arranged in the storage groove. The armrest frame 61 and the cleaning frame 62 are connected by a rotating shaft and a rotating motor. A ventilation groove 621 is provided inside the cleaning frame 62, and fan blades 622 and a transmission assembly 623 are provided inside the ventilation groove 621. A cleaning disk 624 and an electromagnet 625 are provided at one end of the cleaning frame 62 close to the bed frame 1, and the electromagnet 625 is arranged between the cleaning disk 624 and the transmission assembly 623. The cleaning disk 624 is connected to the transmission assembly 623, and a magnetic block is provided at one end of the cleaning disk 624 close to the electromagnet 625.

[0050] The present invention is provided with heating tubes inside the bed frame 1 and the pillow pad 4, which can provide a comfortable environment for patients in winter on the one hand, and can accelerate the drying speed of the bed frame 1 and the pillow pad 4 after disinfection. Finally, the present invention is also provided with a cleaning mechanism 6. After the disinfectant finishes disinfecting the bed frame 1 and the pillow pad 4, the cleaning frame 62 is controlled by a rotating motor to extend out of the storage slot and parallel to the foot board 3, and then the electromagnet 625 is turned on, so that the electromagnet 625 generates a set of magnetic fields that repel the magnetic blocks on the cleaning disk 624. At this time, under the action of the magnetic field repulsion, the cleaning disk 624 will descend and contact the bed frame 1, and the handrail frame 61 and the cleaning disk 624 are controlled to move by the linear motor, and the bed frame 1 is cleaned and deliquified and decontaminated by the cleaning disk 624.

[0051] like Figure 1 , Figure 9-12 As shown, the transmission assembly 623 includes a fixed frame 6231, a bevel gear assembly 6232, a sleeve 6233 and a transmission rod 6234. The sleeve 6233 is connected to the fan blade 622 through the bevel gear assembly 6232. The transmission rod 6234 is arranged inside the sleeve 6233. One end of the transmission rod 6234 extends into the sleeve 6233. The other end of the sleeve 6233 is connected to the cleaning disc 624. A compression spring is arranged at the end of the transmission rod 6234 extending into the sleeve 6233. An ultraviolet sterilization lamp is also arranged at the end of the cleaning frame 62 close to the bed frame 1.

[0052] Through the above technical scheme, the present invention is also provided with a fan. When the cleaning mechanism 6 is working, the fan is in an open state. The airflow generated by the fan accelerates the evaporation rate of the liquid on the one hand, and drives the fan blades 622 to rotate on the other hand. When the fan blades 622 rotate, the sleeve 6233 and the transmission rod 6234 will rotate with the cleaning disc 624. The rotation of the cleaning disc 624 can increase the stain removal effect, and achieve the purpose of leveling the bed frame 1, reducing the probability of wrinkles and the like on the bed frame 1, and increasing the sterilization effect through the ultraviolet sterilization lamp.

[0053] The working principle of the present invention is as follows: when the patient lies on the bed frame 1, the gas in the working tank 54 is sucked into the detection chamber 533 through the suction machine 532 to detect whether the disinfectant in the liquid storage chamber 51 evaporates to the outside. If the patient needs to urinate, the reversing plate 251 is driven to rotate by the reversing motor so that the inclined surface of the reversing plate 251 faces the second waste liquid chamber 22, and then the patient's urine can be discharged into the second waste liquid chamber 22 through the urinary catheter. When the patient leaves the bed frame 1 and needs to sterilize and clean the nursing bed, the reversing plate 251 is driven to rotate by the reversing motor so that the inclined surface of the reversing plate 251 faces the first waste liquid chamber 21, and then the spray frame 55 is controlled to move to the pillow 4 through the electric lifting rod and the electric turntable. Above, the second liquid pump 52 and a set of valves extending into the disinfectant are turned on, and the disinfectant in the liquid storage chamber 51 is sprayed onto the top of the pillow 4 through the second liquid pump 52, thereby sterilizing and disinfecting the pillow 4 and the bed frame 1. When the disinfection is completed, the cleaning frame 62 is controlled by the rotating motor to extend out of the storage slot and parallel to the footboard 3, and then the electromagnet 625 and the fan are turned on, and the cleaning disc 624 is lowered and contacted with the bed frame 1 through the electromagnet 625, and the armrest frame 61 and the cleaning disc 624 are controlled to move by the linear motor, and the bed frame 1 is cleaned and deliquified and decontaminated by the cleaning disc 624, and the cleaning disc 624 is driven to rotate while moving by the fan and the fan blades 622 to increase the decontamination effect.
