Description
Technical field
The utility model discloses a kind of inflator, special relevant with a kind of automatic adjustment air pressure air pump.
Background technique
Air pump is exactly a kind of device that adds air from an enclosed space deaeration or from enclosed space.Existing air pump control inflation mode is simple, just carries out work continually behind the startup power supply.
But existing air pump work is single, can not carry out free adjusting according to the actual requirements, and is excessive through normal atmospheric pressure when causing inflating, the life-span of damaging caisson, or air pressure is too small, causes caisson to use quantity not sufficient.
Given this, the inventor designs a kind of automatic adjustment air pressure air pump, and this case produces thus.
The model utility content
The purpose of the utility model is to provide a kind of automatic adjustment air pressure air pump, and dynamic adjustments air pressure size makes inflation flexibly, efficient energy-saving according to the actual requirements.
In order to achieve the above object, the utility model is realized through following technological scheme:
A kind of automatic adjustment air pressure air pump comprises microprocessor, pressure transducer, variable resistor, inflation motor, air pump, gas tube; Wherein pressure transducer, variable resistor, inflation motor are electrically connected microprocessor; The work of inflation motor driven air pump, gas tube is connected to the gas in the air pump in the outside air cushion; Actual pressure and actual pressure value that pressure transducer is used for detecting gas tube reach microprocessor; Variable resistor is used to set the standard atmosphere pressure value of microprocessor; Microprocessor will gather the actual pressure value and standard atmosphere pressure numerical value compares, and draws control signal and delivers to the inflation motor.
The detected actual pressure value of described pressure transducer inputs in the microprocessor through signal amplifier.
Described microprocessor converts DC-voltage supply by the external communication electricity to through electric pressure converter.
The control signal that described microprocessor produces is sent in the inflation motor through signal rectifier.
Form a branched pipe on the described gas tube, pressure transducer is arranged in this branched pipe and detects the actual pressure value
After adopting such scheme, the utlity model has many beneficial effects:
In the utility model mainly is the setup pressure value of gathering actual pressure value and the required setting of user; See through the microprocessor internal program and carry out both pressure ratios; If the actual pressure value is less than setup pressure value; Then just drive the inflation motor does inflation to outside air cushion function when pressure has reached setting value, just stop output, reach the effect of control.
The pressure sensor signal of the utility model system is through necessary signal amplifier; Testing signal is formed required signal magnitude in the microprocessor; The control signal of output is carried out signal rectification through rectifier simultaneously; Make the output signal conversion become to be used to control the signal of inflation motor, signal conveys is stable between the whole system.
Description of drawings
Fig. 1 is the general structure schematic representation of the utility model preferred embodiment;
Fig. 2 is the circuit structure control graph of the utility model preferred embodiment.
Embodiment
In conjunction with Fig. 1～Fig. 2, preferred embodiment explains further details to the utility model.
A kind of automatic adjustment air pressure air pump, the parts that are mainly concerned with comprise microprocessor 1, pressure transducer 2, signal amplifier 3, variable resistor 4, electric pressure converter 5, rectifier 6, inflation motor 7, air pump (not shown), gas tube 9, inflation interface 10.
The utility model is processed the housing 11 among Fig. 1, on housing, offers perforate 12, and gas tube 9 passes the external air pump of perforate 12, one ends, and the other end connects the inflation interface 13 that fixes on housing 11, gives outside air cushion inflation through inflation interface 13.At branched pipe 14 of 9 fens expenditures of gas tube, be connected to pressure transducer 2 on the branched pipe 14, housing 11 is provided with variable resistor 4 simultaneously, and operator are through regulating the resistance of variable resistor 4, and air pressure is set in adjusting.
The electrical principle of the utility model is as shown in Figure 2, and pressure transducer 2, variable resistor 4, inflation motor 7 are electrically connected with microprocessor 1 respectively, and microprocessor 1 is the core component of data processing, can adopt various data processing chips in the present electronic technology field.Microprocessor 1 is realized AC-DC conversion by the external communication electricity through electric pressure converter 5 in the present embodiment, converts powered by direct current work to.
Actual pressure value on the detection gas tube 9 of pressure transducer 2, resulting data based appropriate signals amplifier 3 are carried out signal and are amplified, and are sent in the microprocessor 1.Signal amplifier 3 changes according to the signal kinds difference flexibly, and this part is known technology by the electronic applications technician, does not do and gives unnecessary details.The resistance of variable resistor 4 also is sent in the microprocessor 1 simultaneously, converts resistance signal to corresponding atmospheric pressure value, understands the setting pressure of the required setting of present operator like this.Microprocessor 1 compares this two class value, if the actual pressure value less than setting atmospheric pressure value, then microprocessor 1 just produces a control signal, drives the inflation motor is done inflation to outside air cushion function.When actual pressure value has reached setting value, just stop output, reach the effect of control.
The output of microprocessor 1 control signal forms stabilization signal and is transported in the inflation motor 7 through rectifier 6 rectification in the present embodiment, starts its work.
The utility model can be regulated inflation motor operations state according to the air pressure situation in the gas tube 9 constantly, and the size of the control air amount of charging and discharging realizes adjustment inner gas pressure automatically.
The foregoing description only be used to explain inventive concept of the utility model, but not to the qualification of the utility model rights protection allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into the protection domain of the utility model.
