At last, it is as follows working principle of the present utility model to be described in detail in detail:

Usually, the air pump of the utility model has inflation, pressurize and bleeds three kinds of mode of operations.

Wherein, modes of inflation system fills the air in the external world fast and squeezes in the mattress inner chamber, uses so that mattress expands and is convenient to do mattress.It is when inflation, driving slide block 41 by this drive unit moves, the switching wind groove 411 that makes slide block 41 is over against being communicated with first air guide channel 35, at this moment, motor 31 impeller 32 high speed rotating form inlet stream, this inlet stream is washed air valve 20 open and is opened second gas port 103, outside air is crossed air port 302, second air compartment 34, first via first gas port 102, second successively and is crossed air port 301, first air compartment 33, first air guide channel 35, switches wind groove 411 and second gas port, 103 backs are charged into (shown in arrow among Fig. 3) in the mattress inner chamber, realizes aerification function.

Pressurize pattern system keeps the swelling state of mattress, when aforementioned inflation is finished and mattress is fully expanded, the user shuts down motor 31 by operation wire controller 50 or knob 43, at this moment, the switching wind groove 411 of this slide block 41 is over against being communicated with first air guide channel 35, because the air pressure in the mattress inner chamber is much larger than the air pressure in the external world, therefore under the draught head effect, this air valve 20 tightly blocks second gas port 103, realizes pressure holding function.

The pattern of bleeding system extracts the air in the mattress inner chamber out, when the user does not need to use and during the collection airbed as mattress, by operating this wire controller 50 or knob 43, driving slide block 41 by this drive unit moves, the switching wind groove 411 that makes slide block 41 is over against being communicated with second air guide channel 36, slide block 41 is in the process of sliding simultaneously, utilize it to push domatic 412 air valve 20 jack-up are opened second gas port 103, simultaneously, form air-flow by motor 31 impeller 32 high speed rotating, this goes out air-flow successively via second gas port 103, switch wind groove 411, second air compartment 34, first crosses air port 301, first air compartment 33, mattress outer (shown in arrow among Fig. 4) is discharged in first air guide channel 35 and first gas port, 102 backs, realizes bleeding function.In addition, this goes out the heat that air-flow also can be taken away motor 31, has the effect of heat radiation.

Design focal point of the present utility model is that it comes moving slider by solenoid valve or knob-operated, utilizes the domatic air valve that backs down that pushes in the slide block then, realizes the switching of the different working modes of air pump thus.With respect to finishing simultaneously for the structure of action of slide block and air valve separately of tradition by the follower lever of solenoid valve, structure of the present utility model is more reasonable, and the layout that makes the win gas port and second gas port has more flexibility, by this, first gas port and second gas port can be arranged at the upper-end surface and the lower end surface of shell respectively, realize straight line over against.Thereby, help shortening the air flow path of inlet stream, make air inlet more direct and rapid, promote the aeration speed and the working efficiency of product.

The above, it only is preferred embodiment of the present utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
