The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described
As shown in Figure 1, power supply air system of the present invention is made up of main body 1, universal air filter 2 and waistband 3, and said main body is connected with the universal air filter through hickey, and the main body dorsal part is waistband fixedly;
Main body as shown in Figure 2 comprises fore shell 4, control panel 5, blower fan 6, surface-mounted integrated circuit 7, seal cover 8, back cover 9, charging inlet 10, battery 11, fin 12, blower fan set casing 13 and subsequent use air inlet sealing-plug 14; Main body cover is made up of fore shell and back cover; The main body cover top is air outlet and control panel fixedly; Be set with the blower fan set casing of blower fan in the main body cover; Set gradually surface-mounted integrated circuit, seal cover and battery between blower fan set casing and the back cover, said back cover is provided with charging inlet.
Power supply air system control section operation principle of the present invention is as shown in Figure 4; Said control system is that the surface-mounted integrated circuit of core is formed by control panel with single-chip microcomputer P89LPC935; Battery is connected with blower fan through the circuit that digital and Adjustable is set; Battery is connected with surface-mounted integrated circuit through expansion battery capacity observation circuit; Blower fan is connected with surface-mounted integrated circuit through expansion air quantity observation circuit, and said control panel is provided with the buzzer siren of water proof switch, air volume adjusting knob, battery electric quantity demonstration LED light, low electric weight and low air quantity and is connected with surface-mounted integrated circuit respectively.
The battery capacity monitoring: because the capacity of battery becomes piecewise linear relation with voltage, the relation table of capacity and voltage when utilizing the discharge of empirical value manufacture batteries.In use, monitor cell voltage in real time, the row interpolation of going forward side by side through tabling look-up calculates and obtains the corresponding battery capacity, and utilizes five LED pilot cell capacity.When battery capacity is lower than setting value, MCU driving LED and buzzer warning.
Air quantity is regulated: realize the control of fan delivery through the supply voltage of control blower fan.Blower fan is by the voltage stabilizing output power supply of digital and Adjustable, and the output voltage of digital and Adjustable is regulated the resistor decision on the pin by being connected in it.Single-chip microcomputer response user's keyboard operation, change can be edited the resistance of resistor, thereby regulates the voltage output of digital and Adjustable.
Low air quantity is reported to the police: decide under the voltage condition, the air quantity of blower fan and fan pressure head pressure are inversely proportional to, and during the increase of fan pressure head pressure, the electric current of blower fan can reduce.So, can realize the monitoring of low air quantity through the current value of monitoring supply blower fan.Under the situation of digital and Adjustable voltage stabilizing output, if supply with the threshold value of the current average of blower fan less than program setting, it is low excessively then to be judged to be air quantity, MCU driving LED and buzzer warning.
Wherein:
Fig. 1 and Fig. 2 air filter 2 must be selected the screw thread bore that meets China or external correlation standard for use, can select the air cleaner of difference in functionality according to actual needs for use.
Fore shell 4, back cover 9 and blower fan set casing 13 materials are selected polystyrene and nylon eutectic among Fig. 2, and weight is lighter when having higher-strength.Fore shell 4 constitutes the passage that air flow jointly with blower fan set casing 13 in the power supply air system.
Surface-mounted integrated circuit 7 among Fig. 2 is used to control power supply air system power switch of the present invention, air quantity adjusting, battery electric quantity demonstration, low electric weight and low air quantity sound and light alarm etc.Operation principle is as shown in Figure 4.
But the battery 11 among Fig. 2 is selected the polymer high-performance lithium battery of recharge for use, also can select battery combination like other performance classes for use.
Self-contained battery 11 on the back cover 9 among Fig. 2 can install and fix waistband 3 simultaneously.
Charging inlet among Fig. 2 is used for also can be used as the interface of external power source to the rechargeable battery charging.
The effect of the subsequent use air inlet sealing-plug 14 among Fig. 2 is when only using 2 air cleaners, seals another air inlet.
The course of work of the present invention is following: when the power supply air system was moved, battery 11 is startup blower fan 6 under the control of integrated circuit 7, and blower fan 6 sucks surrounding air in the power supply air system through filter 2.During air process filter 2, harmful substance wherein (particle, gas or steam) will be intercepted.What discharge from power supply air system air outlet is the pure air with certain flow and pressure, can be through passages such as flexible pipes to other protective gears conveyings.
Under special circumstances, too high or bigger to the air quantity requirement like the air cleaner resistance, then the present invention provides another kind of 3 filter power supply air systems.As shown in Figure 3,3 air cleaners can significantly reduce the air velocity through each filter, thereby reduce the integrated air resistance of filter.Certainly, under the situation that weight and other parameters allow, the number that still can append air inlet and filter is to realize special requirement.
Embodiment: when power supply air system of the present invention and certain malleation Protective clothes combined with cap and mask are used (as shown in Figure 5), it is as shown in table 1 below specifically to detect its performance.
Parameter actual measurement when table 1 power supply air system of the present invention and certain malleation Protective clothes combined with cap and mask are used
Can find out from measured result under the moderate respiratory intensity, no matter exhale or air-breathing; The power supply air system all can make and keep certain malleation value in the malleation Protective clothes combined with cap and mask; Noise is lower than 75dB, and the working time, each item indication and warning function operation were normal on average greater than 6 hours.
Although for illustrative purposes, provided embodiments of the invention, those skilled in the art all can not break away under the appended claims book scope of the present invention, and it is carried out multiple modification and additional.Power supply air system of the present invention is not limited to be used for medical malleation head-shield, and other all can supporting use the present invention such as respiratory protection mask, the helmet, head-shield and protective garment.
