The working principle that the present embodiment is described in detail is as follows:

When needing to carry out bidirectional inflating using big pump, switching mechanism 50 is pushed into side in place, so that the big cylinder 20 of activity Can be up and down together with the small cylinder 30 of activity, meanwhile, switching switch 70 is allocated to two-way position so that cock body 71 block the 5th into Stomata 106 and close；Then, when pulling up movable small cylinder 30 by handle 40, the big activity upwards of cylinder 20 of activity, external gas Body enters in the first air cavity 101 from the first air inlet 102, then, successively passes through upper air gap 104, first annular embedding slot 204, inlet channel 203 and third air inlet 202 and enter the second air cavity 201, then, enter the by the 4th air inlet 302 In three air cavitys 301, and the gas in third air cavity 301 is entered in inflatable substrate inside by venthole 41.Instantly handle hand 40 When, extraneous gas enters in the first air cavity 101 from the second air inlet 103, then in turn through lower air inlet gap 105, the first ring Shape embedding slot 204, inlet channel 203 and third air inlet 202 and enter the second air cavity 201, then, by the 4th air inlet 302 enter in third air cavity 301, and the gas in third air cavity 301 is entered in inflatable substrate inside by venthole 41.

When needing to be switched to big pump unidirectionally inflation, as shown in Figure 6 to 8, switching switch 70 is allocated to check position, is made The 5th air inlet 106 is obtained to open；When pulling up movable small cylinder 30 by handle 40, extraneous gas is from the first air inlet 102 The external world is exported from the 5th air inlet 106 into the first air cavity 101, while again, so that pull on handle 40 easily, it will not be to inflation Object is inflated；Instantly when handle hand 40, extraneous gas enters in the first air cavity 101 from the second air inlet 103, then successively passes through It crosses down air inlet gap 105, first annular embedding slot 204, inlet channel 203 and third air inlet 202 and enters the second air cavity 201, then, enter in third air cavity 301 by the 4th air inlet 302, and the gas in third air cavity 301 passes through venthole 41 enter in inflatable substrate inside.

When being inflated using small pump, for unidirectional inflation, switching mechanism 50 is pushed into the other side in place, the activity is big Cylinder 20 is fixed, and the big cylinder 20 of the small cylinder 30 of activity activity relatively is movable, external when pulling up movable small cylinder 30 by handle 40 Gas enters in the first air cavity 101 from the first air inlet 102, while exporting the external world from the 5th air inlet 106 again, so that pulling on handle Hand 40 easily, will not be inflated inflatable substrate, and instantly when handle hand 40, which is closed, and the 4th is unidirectional Air valve 34 is opened, and the gas in the second air cavity 201 is entered in third air cavity 301 by the 4th air inlet 302, and third air cavity Gas in 301 is entered in inflatable substrate inside by venthole 41.

The design focal point of the utility model is: firstly, utilizing switching switch control the 5th by being provided with switching switch Air inlet opens or closes, and to realize that big pump bi-directionally or uni-directionally inflated toggles, volumetric efficiency is can be improved in when bidirectional inflating, It when unidirectional inflation, above pulls handle easily, can be realized using human body self gravity when pushing handle, inflatable substrate is sufficiently beaten in guarantee Full, product uses more flexible and convenient, also more hommization.Secondly, increase cap by being provided with, to form extension air flue, Extend the inlet end height of air flue close to the middle height position of ontology, is located at body bottom portion instead of the product inlet end of tradition Mode, to effectively prevent the sundries such as water, the grains of sand, mud during (such as sandy beach) use outdoors and enter in air flue, Guarantee airway patency.

The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model Any restrictions, therefore any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent change Change and modify, is still within the scope of the technical solutions of the present invention.
