7. A method for installing and using a portable nursing bed according to any one of claims 1 to 6, characterized in that: The steps include: S1. Assembling the outer frame, connecting the pipes of the outer frame and tightening them with bolts; S2, assembling the inner frame, first assemble and fix the pipe fittings of the inner frame by bolts to form a frame and a supporting beam, then insert the positioning tubes on the four square tubes into the through holes of the square tubes respectively, then install the fixing seat by bolts on the front and rear sides of the bottom of the inner frame, install the transmission rod through the bearing on the fixing seat, install the motor bracket by bolts at the end of the inner frame, install the driving motor on the motor bracket by bolts, and connect the driving wheel of the driving motor with the sprocket through a chain, and finally mount the square tube on the swing wheel of the transmission rod; S3, assembling the dirt accumulation mechanism, clamping the guide plates at both ends of the dirt accumulation plate, and installing the sewage discharge pipe at the sewage discharge port of the dirt accumulation plate through the flange; S4, assembling the support mechanism, inserting the branch pipe into the inner side of the rectangular frame along the top, then inserting the buffer spring along the bottom end of the branch pipe, then continuing to make the bottom end of the branch pipe pass through the bottom of the rectangular frame, and finally inserting the retaining spring into the groove reserved in the upper half of the branch pipe; S5. Assemble the whole. Invert the assembled outer frame and invert the inner frame on the inner side of the outer frame. Then assemble the inner frame and the outer frame by bolts. After the assembly is completed, straighten the whole. Put the assembled support mechanisms into the guide grooves one by one. After all the support mechanisms are placed, install the end plates and the peripheral side plates on the upper surface of the outer frame by bolts, and embed the fixing plates on the outer sides of the peripheral side plates and the end plates by screws. After the support rods are inserted into the holes of the fixing plates, a heat preservation cover is set between the multiple support rods and the heat preservation cover is sealed with the edge of the outer frame. Then, the accumulated dirt is removed. The mechanism is directly snapped or installed at the bottom of the inner frame by bolts, the sewage pipe is connected to the inlet of the sewage tank through the adapter tube, the delivery pipe is inserted and installed along the reserved hole, and the delivery joints on at least one delivery pipe are connected to the adapter at the location where the flushing operation is required by using a plastic pipe, the above delivery pipes are connected to the water pump in the warm water tank by using a conduit, and the remaining delivery pipes are connected to the warm air system, the delivery joints on the delivery pipes connected to the warm air system are connected to the adapter at the location where the warm air operation is required by using a plastic pipe, and the edge of the dirt accumulation mechanism and the inner frame are sealed with a sealing strip; The specific method of using the nursing bed is as follows: when in use, a raindrop sensor is arranged under the inner frame, and the water pump, the drive motor, and the warm air system are connected to the computer, and a pillow is placed on the end plate. After the patient lies on the nursing bed, the thermal cover is closed. When the patient urinates or defecates, the raindrop sensor will sense the signal and transmit it to the computer. The computer controls the start of the drive motor and the water pump, and the drive motor drives the transmission rod to rotate. As the transmission rod rotates, the two square tubes at the same end reciprocate up and down, so that the square tubes lift up the adjacent supporting mechanism to reciprocate up and down. The water pump draws warm water and transmits it to the spray hole through the delivery pipe connected to it for spraying and flushing, so that the excrement falls into the dirt accumulation mechanism and flows into the sewage tank for collection. After flushing, the computer controls the warm air system to blow out dry warm air through the delivery pipe connected to it through the spray hole to quickly dry the moisture on the patient and the bed.
