Under this kind of scheme, the water in the water tank needs to be preheated before flushing, and it takes a long time to wait from heating to flushing
At the same time, this solution uses independent temperature and liquid level sensors. When the sensor fails, it is prone to the danger of dry heating in the heating chamber.
In addition, the control circuit required by the independent water tank heating automatic flushing scheme is relatively complicated, and the required components are more, and the cost is higher

Embodiment 1
[0039] Such as Figure 1-2 As shown, an intelligent cleaning device for nursing beds includes a housing 1, a main control 2 arranged in the housing 1, a solenoid valve 3, an instant water heater 4, a water diversion valve 5, a flushing nozzle 6, a heating The fan 7; the flushing device is connected to the water source, and the solenoid valve 3 controls the on-off of the waterway; the output end of the solenoid valve is connected to the input end of the instant water heater 4, and the output end of the instant water heater 4 is connected to the water diversion valve 5; the water diversion valve 5 Connect the flushing nozzle 6; the main controller 2 controls the solenoid valve 3, the instant water heater 4, the water diversion valve 5, the flushing nozzle 6 and the hot air blower 7.
[0040] The water source includes a water tank and a water pump, the water tank and the water pump, the water pump is arranged at the outlet of the water tank, and the water pump is connected to the...
Embodiment 2
[0066] Such as Figure 12 As shown, an intelligent cleaning method for a nursing bed, step A, sends an instruction to the main controller; step B, the main controller judges whether the power is enabled, and if the power is enabled, then judges whether the water pump and the fan are working , if so, stop receiving new instructions, if the water pump and fan are not working, then enter the next step; step C, first erase the EEPROM content, and then set the steps of the water diversion valve; step D, set the gear status output; Step E, drive the water diversion valve and the nozzle to advance to a suitable position; Step F, turn on the pressure reducing valve and the water pump in turn; Step G, modify the content of the communication array; Step H, write the content to the two addresses of the EEPROM after modifying the array.
[0067] When the MCU receives the flushing command (universal flushing, female flushing), it first judges whether it is currently in the power-enabled st...

Abstract
The invention relates to the technical field of medical equipment and particularly relates to an intelligent washing device for a nursing bed. The intelligent washing device for a nursing bed comprises a shell, a master controller, an electromagnetic valve, an instantaneous water heater, a shunt valve, a flushing sprayer and an air heater, wherein the master controller, the electromagnetic valve,the instantaneous water heater, the shunt valve, the flushing sprayer and the air heater are arranged in the shell; the output end of the electromagnetic valve is connected with the input end of the instantaneous water heater; the output end of the instantaneous water heater is connected with the shunt valve; the shunt valve is connected with the flushing sprayer; and the master controller is usedfor controlling the electromagnetic valve, the instantaneous water heater, the shunt valve, the flushing sprayer and the air heater. According to the intelligent washing device, different persons canbe washed due to the design of the shunt valve, the users have good experience and comfortable feeling; an instantaneous water heat module is arranged in the flushing sprayer, water is heated in thesprayer,, and heat waste and use cost increase caused by heating the water in a water tank can be avoided; and the washing method can achieve automatic washing and drying functions, and work can be continued by reading the last work state even the device is powdered down suddenly and powered on once again in the using process.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an intelligent cleaning device and cleaning method for nursing beds. Background technique [0002] The automatic flushing system is applied to medical care beds, and its function is to help patients with limited mobility to clean and dry themselves after going to the toilet. At present, the concept of automatic flushing is widely used in the field of smart toilets. In the field of medical care, the concept of automatic flushing is less widely used. [0003] At present, the heating scheme of the domestic automatic flushing device mainly adopts the independent water tank heating type. Under such schemes, the water in the water tank needs to be preheated before flushing, and it takes a long time to wait from heating to flushing. At the same time, this solution uses independent temperature and liquid level sensors. When the sensor fails, it is prone to the danger of dry he...
