Description
Technical field
The present invention relates to a kind of aspirator that possesses real-time gas pressure measuring ability, in order to solve the just suction of the flushing water in the water pipe problem between process chambers and the recycling bin of urine in the intelligent treating device for urination and defecation.
Background technology
In the prior art; The urine of intelligence in the treating device for urination and defecation just between process chambers and the recycling bin flushing water suction method in the water pipe be between recycling bin and air pump, to add electromagnetic valve; The gentle pipe of energy storage canister forms gas circuit; At first close electromagnetic valve and prevent that ambient atmos from getting into, booster air pump begins tracheae and energy storage pump are bled, and whole gas circuit forms certain negative pressure after suction a period of time.Opens solenoid valve then because action of negative pressure, urinates just that the flushing water in the water pipe is inhaled into recycling bin between the process chambers and recycling bin.
There is following shortcoming in said method: at first, this method can only be in advance through deciding suction effect the switch time of experiment test electromagnetic valve and air pump, can not should the time according to the dynamic adjustment of the force value in the actual gas circuit, suction effect is not ideal enough.Secondly, owing to lack real-time pressure monitoring, when the electromagnetic valve in the gas circuit, air pump, when tracheae breaks down, certainly will cause the aspirator operation irregularity, system can't real-time perception.
Summary of the invention
The objective of the invention is shortcoming, a kind of aspirator that possesses real-time gas pressure measuring ability is provided to prior art.
The present invention realizes through following technical scheme: between recycling bin and air pump, add electromagnetic valve, the gentle pipe of energy storage canister forms gas circuit, simultaneously; On energy storage is irritated, install a pressure sensor additional, sensor is connected to single-chip microcomputer, at first close electromagnetic valve and prevent that ambient atmos from getting into; Booster air pump begins tracheae and energy storage pump are bled; Device shows the negative pressure value in the gas circuit in real time, when reaching the negative pressure value of setting, and opens solenoid valve; This moment is because action of negative pressure, urinates just that the flushing water in the water pipe is inhaled into recycling bin between the process chambers and recycling bin.If suction effect is not good, then can adjust the switch time of electromagnetic valve and air pump through the actual pressure value in the gas circuit, reach best suction effect.This device can be monitored the unusual of gas circuit components and parts and pipeline through real-time force value simultaneously.
The present invention includes aspiration circuit part and Single-chip Controlling part, just partly form by process chambers, recycling bin, electromagnetic valve, energy storage canister, pressure sensor, strainer, air pump, sound absorber, Single-chip Controlling by the urine of intelligent treating device for urination and defecation for its structure.Urinate just that process chambers is connected through water pipe with recycling bin, recycling bin, electromagnetic valve, energy storage canister, strainer, air pump, sound absorber connect through tracheae according to turnover gas mode, and pressure sensor is connected through the internal thread of external screw thread and energy storage canister.Pressure sensor partly is connected with Single-chip Controlling through lead.

It below is the workflow of this aspirator.
Single-chip microcomputer U1 at first accomplishes initialization; Its main purpose is to accomplish the configuration of input and output pin, Abort Timer; Close electromagnetic valve then and prevent that ambient atmos from getting into; Booster air pump begins tracheae and energy storage pump are bled, and pressure sensor carries out data acquisition to the pressure of energy storage canister internal gas simultaneously, and the analog quantity that collects is inputed to single-chip microcomputer PF0 pin.Single-chip microcomputer starts the AD conversion routine after receiving the analog quantity of input.Behind the AD EOC, SCM system returns actual force value and is presented on the LCD screen.Program compares through the force value that gets access to and the value of setting in advance, requires then opens electromagnetic valve if meet the negative pressure of suction, just the flushing water in the water pipe aspirates between process chambers and the recycling bin to urinating.Do not require then continue to aspirate if meet the negative pressure of suction, till reaching default value.Suction is closed electromagnetic valve and air pump after finishing.
The workflow of AD conversion routine is when receiving the analog quantity that pressure sensor sends here as single-chip microcomputer pin PF0; At first control is carried out initialization with status register ADCSRA to single-chip microcomputer inside ADC multiplex's mask register ADMUX and ADC, the AD translative mode is set for starting AD sampling single channel ADC0, and external voltage 5V benchmark is imported; The transformation result Right Aligns; ADC pre-divider Frequency Dividing Factor is 64, begins to carry out digital-to-analogue conversion then, when ADC interrupt identification ADIF is 0; Digital-to-analogue conversion is not accomplished, and program is then changed.When ADC interrupt identification ADIF was 1, digital-to-analogue conversion finished, and transformation result is returned main program.
Beneficial effect of the present invention:
Adopts pressure sensor is gathered the gas circuit pressure of aspirator; According to the unlatching and the turn-off time of electromagnetic valve and air pump in the force value real-time and dynamic adjusting device that collects; Solve the just suction of the flushing water in the water pipe problem between process chambers and the recycling bin of urine in the intelligent treating device for urination and defecation, reached suction effect preferably.
This device has real-time pressure monitoring; When the electromagnetic valve in the gas circuit, air pump, when tracheae breaks down; Its force value also can occur unusually, and system can real-time perception also sends corresponding out-of-work order, so this device has certain fault function of saving oneself.
This apparatus structure is succinct, and is easy to use, and automaticity is higher.
