Accompanying drawing explanation
Fig. 1 is the structural representation of the stage aerosol sprayer oil-free protection device that embodiment proposes.
Fig. 2 is the theory diagram of the stage aerosol sprayer oil-free protection device that embodiment proposes.
In Fig. 1: 10-oil pump, 20-oil bottle, 30-heater, the spy of 40-temperature, 50-control circuit plate.
Detailed description of the invention
This utility model is retouched further below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that
State.
Referring to Fig. 1 to Fig. 2, a kind of the stage aerosol sprayer oil-free protection device that embodiment proposes, including oil pump 10, oil bottle
20, heater 30, temperature probe 40 and control circuit plate 50；Wherein, temperature probe 40 is preferably thermocouple, certainly
Can also other temperature-sensitive devices；Oil pump 10 two ends are connected by pipeline with oil bottle 20, heater 30 respectively, with by oil bottle 20
In oil pump to heater 30 heating, atomization can be produced after being heated to uniform temperature, externally spray smog；Oil pump 10,
Heater 30, temperature probe 40 electrically connect with control circuit plate 50 respectively；Temperature probe 40 contacts with heater 30 with inspection
Surveying the heating-up temperature of heater 30, control circuit plate 50 controls the work of heater 30 according to the testing result of temperature probe 40
State, and according to the heater 30 operating time in Preset Time, and according to heater 30 variations in temperature when aerosol spraying
Situation determines whether oil pump 10 is supplied oil and entered heater 30, to judge oil bottle 20 whether oil-free corresponding control oil pump 10
Duty, as judged, oil-free then control oil pump 10 quits work state, if it is determined that there is oil then oil pump 10 to work on.
In the present embodiment, the structure of control circuit plate substantially refers to the design of Fig. 2, has heater control unit 51, master
Control unit 52 and oil pump control unit 53；Wherein, heater control unit 51 respectively with heater 30, main control unit 52
Electrical connection；Temperature probe 40 electrically connects with main control unit 52；Oil pump control unit 53 respectively with oil pump 10, main control unit 52
Electrical connection.Wherein, heater control unit 51 can be specifically the device such as relay or controllable silicon, and main control unit 52 leads to accordingly
Cross this relay or controllable silicon and electrically connect to control the duty of heater 30 with heater 30.Certainly, oil pump 10 controls
The concrete sample of unit 53 can be the device such as relay or controllable silicon.
The machine parameter configuration of the oil pump 10 of the present embodiment may is that pressure is 1.5MPa～2.0MPa, and flow is
350ml/min～400ml/min, power is 50W, certainly, is the most only citing, and not as restriction.
Operation principle
The process of the stage aerosol sprayer aerosol spraying is: heating pumped to heater 30 by the oil in oil bottle 20 by oil pump 10, is heated to
Smog can be produced after uniform temperature in the pipeline of heater 30, temperature probe 40 by the Temperature Feedback detected to controlling electricity
In road plate 50 (main control unit 52), control circuit plate 50 (heater control unit 51) i.e. controls heater 30 power-off
To suspend heating；Owing to ree-oil atomization can take away the heat of heater 30, cause the temperature rapid decrease of heater 30, temperature
Probe 40 by the Temperature Feedback that detects to control circuit plate 50, control circuit plate 50 i.e. control heater 30 is powered with
Heat.If fog machine (oil bottle 20) oil-free, oil pump 10 still can work, but does not has oil to enter the pipe of heater 30
In road, the temperature of heater 30 declines can slowly, and control circuit plate 50 supplies electrical heating also will not to heater 30, when
Control circuit plate 50 calculate in Preset Time to heater 30 heat time heating time (operating time) less than setting value time, and
When determining that oil pump 10 unavailability oil enter heater 30 according to heater 30 variations in temperature when aerosol spraying, then judge oil bottle 20
Oil-free, and control oil pump 10 quits work, thus protect oil pump 10.
The present embodiment does not increase hardware cost just can realize the protection to oil pump 10, and is made without debugging, it is judged that accurately.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed, but also
Therefore the restriction to this utility model the scope of the claims can not be interpreted as.It should be pointed out that, for the ordinary skill of this area
For personnel, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into
Protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
