Referring to FIGS. 1-2, an inflator device includes

Outsourcing 1; the outer bag 1 is internally provided with an air chamber 13, the outer bag 1 is provided with a ventilation passage, and the ventilation passage is used for communicating the air chamber 13 with the outside; in the present embodiment, the ventilation passage preferably includes a first ventilation passage 14 and a second ventilation passage 15, the first ventilation passage 14 is provided with the air inlet nozzle 3, and the second ventilation passage 15 is provided with the air outlet nozzle 2; preferably, only the first one-way valve 31 is installed in the air inlet nozzle 3, the first one-way valve 31 comprises a flexible valve plate, when the outer bag is pressed, the valve plate is attached to an inner hole of the air inlet nozzle to seal the air inlet nozzle 3, namely, the first ventilation channel 14 is cut off, so that the air chamber cannot be communicated with the outside through the first ventilation channel 14, the air in the air chamber can be discharged outwards only through the air outlet nozzle 2 on the second ventilation channel 15, and if the air outlet nozzle 2 is communicated with an inflatable product, the air discharged from the air chamber can be inflated into an air bag of the inflatable product; after the outer bag is released, the inner part of the air chamber is in a vacuum state, the valve plate is pushed by external air pressure, the valve plate partially bends and moves towards the inner part of the outer bag, the first ventilation channel 14 is communicated with the air chamber, and air outside the air chamber enters the air chamber. It should be noted that, only when the first check valve 31 is installed in the nozzle, an inflatable product requiring a check valve at the inlet of the inflatable product to be inflated is used. (the one-way valve can only allow gas to enter the bladder of the inflatable product and block gas in the bladder from being expelled outwards).

As a further preferred feature of the present embodiment, a second one-way valve 21 may be further disposed on the air outlet 2, the second one-way valve 21 also has a valve plate, the second one-way valve 21 is just opposite to the first one-way valve 31, when the outer bag is pressed, the valve plate of the second one-way valve 21 is bent and moved outward of the air chamber, and the air chamber is communicated with the inflatable product through the second ventilation channel 15, so that the air in the air chamber is inflated into the inflatable product; when releasing the outsourcing, the inside vacuum state that presents of air chamber, outside atmospheric pressure pastes the valve block of second check valve 21 in the hole of play gas nozzle tightly, seals the play gas nozzle, is about to cut off second air passage 15 for the outside air chamber of air chamber can't enter into the air chamber through play gas nozzle 2.

The inside pressure spring that often uses of traditional pump of pressing keeps the shape of air chamber, and the problem that the pressure spring exists is that the hand is comparatively laboured to require to press the point of application of force and will be located on the pressure spring or the pressure spring is peripheral, and it still has the volume great, is difficult to reduce itself volume, thereby leads to carrying and accomodates inconveniently. For this reason, in the present embodiment, it is preferable that the air chamber 13 is filled with the elastic filler 131; specifically, preferred elastic filler 131 is monoblock sponge or foaming sponge, has replaced traditional push type air pump to adopt pressure spring help outsourcing to kick-back, and traditional pressure spring of relative ratio, this application can be realized aerifing in arbitrary extrusion outsourcing.

Further, in the present embodiment, the outer cover 1 preferably includes an upper sheet 11, a lower sheet 16, and side walls 12, the upper sheet 11, the lower sheet 16, and the side walls 12 are all made of an airtight flexible material, and the upper sheet 11, the lower sheet 16, and the side walls 12 may preferably be made of any one of TPU, PVC, and EVA; in the embodiment, the edges of the upper sheet 11 and the lower sheet 16 are respectively fixedly connected with the edges of the side wall 12; preferably, the edges of the upper sheet 11 and the lower sheet 16 are fixedly connected with the edges of the side wall 12 by welding. The upper sheet 11, the lower sheet 16, and the side gusset 12 may be cut out as required by design, and in the present embodiment, the first ventilation path 14 and the second ventilation path 15 are preferably formed by opening holes in the side gusset 12 and the upper sheet 11. The air inlet nozzle 3 and the air outlet nozzle 2 are fixedly connected with the edges of the first ventilation channel 14 and the second ventilation channel 15 in a bonding or welding mode, so that connection and sealing are formed, and air can only enter or exit the air chamber through the air inlet nozzle 3 and the air outlet nozzle 2. The first check valve 31 and the second check valve 21 in this embodiment may be integrated with the inlet nozzle 3 and the outlet nozzle 2, and it should be noted that the inlet nozzle or the outlet nozzle structure with the check valves is the prior art.

Further, the present embodiment further includes a sealing assembly 32, where the sealing assembly 32 is detachably mounted on the intake nozzle 3, and in the present embodiment, the sealing assembly 32 is preferably an assembly that can completely seal the intake port, such as a rubber cover, a plastic cover, or a rubber plug; when the air inflation is finished and the air is required to be stored, due to the use of the flexible material outer bag and the porous flexible material in the air chamber, after the air in the air chamber is extruded and discharged, the sealing plug is plugged into the air inlet to seal the air inlet, at the moment, the air in the air chamber is discharged outwards through the air outlet by pressing the outer bag, and due to the fact that the air inlet is sealed, the outer bag cannot be restored to an original state under the action of atmospheric pressure, the volume of the whole air inflation device is reduced to the minimum, and the air inflation device can be curled, so that the carrying and the storage are convenient, and detailed figures 3-4 are shown; when needing to inflate, the sealing plug is dismantled, and the air alright can enter into the air chamber from the air chamber outside through the air inlet this moment, and the outsourcing resumes original state under the elastic action of foaming sponge itself to this aerating device can normal use.

With reference to fig. 1, the present embodiment further includes an inflation connection pipe 4, one end of the inflation connection pipe 4 is detachably connected to the air outlet 2, so that the other end of the inflation connection pipe 4 can be connected to the inflation nozzle of the inflation product, thereby facilitating the use of the inflation device and reducing the requirement of the inflation device for inflating and placing positions.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
