The utility model circuit theory is following:
During inflated condition, moving seesaw-type double-pole-double-throw switch 60 is upwards closed, and at this moment, motor 21 is connected; Solenoid valve 321 is an off state, because 54 be pressure-sensitive switch, when above-mentioned air pressure sense cell 52 did not touch 54,54 was on-state; Motor 21 and power connection begin inflation, and when filling when full, air pressure reaches certain value; Air pressure sense cell 52 touches 54,54 and breaks off, and motor 21 is shut down, and stops inflation;
When bleeding state, moving seesaw-type double-pole-double-throw switch 60 is closed downwards, solenoid valve 321 and motor 21 parallel connections and power connection; Solenoid valve 321 switching-overs, motor 21 starts simultaneously, begins to bleed; When exhausting gas, air pressure descends in the inflatable product 90, and air pressure sense cell 52 resets and separates with 54; 54 connect, and motor shutdown stops to bleed;
When using a teleswitch inflation, pin fine motion formula switch 70, shell fragment is closed left on the fine motion this moment formula switch 70, and at this moment, motor 21 and power connection begin inflation, when unclamping fine motion formula switch 70, stop inflation, and simultaneously, shell fragment is upwards closed on the fine motion formula switch 70;
Use a teleswitch when bleeding, pin fine motion formula double-pole-double-throw switch 80, shell fragment is upwards closed on the air-breathing switch 80 of remote controller this moment; Because when fine motion formula switch 70 was not pinned, shell fragment was upwards closed on it, thereby; Motor 21 and solenoid valve 321 parallel connections and power connection; Begin to bleed, unclamp fine motion formula double-pole-double-throw switch 80, stop to bleed.
The working principle of the utility model is following:
Usually, the air pump of the utility model has inflation, pressurize and bleeds three kinds of mode of operations.
Wherein, modes of inflation is as shown in Figure 3, is that air with the external world fills fast and squeezes in inflatable product 90 inner chambers, and it is when inflation; The user is upwards closed with moving seesaw-type double-pole-double-throw switch 60, and at this moment, motor 21 is connected, and solenoid valve 321 is an off state; Because 54 is pressure-sensitive switch, when above-mentioned air pressure sense cell 52 did not touch 54,54 was on-state, motor 21 and power connection; Begin inflation, motor 21 impeller 22 high speed rotating form inlet stream, and this inlet stream is washed air valve 40 open or air valve 40 is backed down and opened second gas port 13 by pushing tow cambered surface 311; This inlet stream is washed air valve 40 open and is opened second gas port 13, and outside air is charged in the product cavity via first gas port 12, second air compartment 24, first air compartment 23, first air port 232 and second gas port, 13 backs, realizes aerification function; When filling when full, air pressure reaches certain value, and air pressure sense cell 52 touches 54; 54 break off, and motor 21 is shut down, and stops inflation;
Another kind of inflation mode: when using a teleswitch inflation, pin fine motion formula switch 70, shell fragment is closed left on the fine motion this moment formula switch 70, at this moment; Motor 21 and power connection begin inflation, when unclamping fine motion formula switch 70; Stop inflation, simultaneously, shell fragment is upwards closed on the fine motion formula switch 70;
The pressurize pattern is as shown in Figure 4, is the swelling state that keeps inflatable product 90, when when aforementioned inflation completion inflatable product 90 fully being expanded; Solenoid valve drive activity wind groove moves and makes on it pushing tow cambered surface leave air valve, and through control switch motor is shut down, at this moment; Because the air pressure in the mattress inner chamber is much larger than ambient pressure; Therefore under the effect of draught head, this air valve tightly blocks second gas port, realizes pressure holding function.
The pattern of bleeding is as shown in Figure 5; System extracts the air in inflatable product 90 inner chambers out, and the user is closed downwards with moving seesaw-type double-pole-double-throw switch 60, solenoid valve 321 and motor 21 parallel connections and power connection; Solenoid valve 321 switching-overs; Simultaneously motor 21 starts, and begins to bleed, and solenoid valve 321 drive activity wind grooves 31 move and make in the movable wind groove 31 pushing tow cambered surfaces 311 back down air valve 40 to open second gas port 13; This is given vent to anger and flows through by second air port 241, second air compartment 24, first air compartment 23, first air port 232 and 12 exhausts of first gas port, thereby realizes inflatable product 90 exhausts.In addition, this goes out the heat that air-flow also can be taken away motor 21, has the effect of heat radiation.When exhausting gas, air pressure descends in the inflatable product 90, and air pressure sense cell 52 resets and separates with 54, and 54 connect, and motor shutdown stops to bleed;
Another kind of air suction mode: use a teleswitch when bleeding, pin fine motion formula double-pole-double-throw switch 80, shell fragment is upwards closed on the fine motion this moment formula double-pole-double-throw switch 80; Because when fine motion formula double-pole-double-throw switch 70 was not pinned, shell fragment was upwards closed on it, thereby; Motor 21 and solenoid valve 321 parallel connections and power connection; Begin to bleed, unclamp fine motion formula double-pole-double-throw switch 80, stop to bleed.
The design focal point of the utility model is, realizes that through a wind direction COMM communication is set the wind direction of blower device switches, and controls the automatic on-off of the switch realization air pump of motor and electromagnetic valve circuit break-make respectively through a pressure responsive element and two.By this, this air pump structure can realize that the inflation and the pattern of bleeding freely change, and can autostop after the air-pump inflating or the end of bleeding; Reduced the loss of manpower, financial resources greatly, be user-friendly to, and; This air pump is simple in structure, and is easy to operate, and automaticity is high; Improve the air pump working efficiency, strengthened product competitive ability.
The above; It only is the preferred embodiment of the utility model; Be not that the technical scope of the utility model is done any restriction; So every technical spirit according to the utility model all still belongs in the scope of the utility model technological scheme any trickle modification, equivalent variations and modification that above embodiment made.
