An inflation connector valve according to an embodiment of the present invention will be described with reference to fig. 1-5, and is primarily used in inflatable products, including but not limited to inflatable tents, inflatable mattresses, and inflatable sofas, which are assembled together in a multi-shape structure having a plurality of air chambers.

The existing inflation connection valve generally adopts two structures, one structure is a bent nozzle structure, and the askew nozzle structure has the advantage that the inflation connection valve can be detachably connected with two air cavities. The bent nozzle structure has the defects that an external connection mode is adopted, and the bent nozzle is easy to bend, so that unsmooth air circulation is caused, and the inflation efficiency is influenced. And the product is exposed outside the product, can not be hidden and is not beautiful enough. The other is a directly welded structure, and has the advantages that the pipeline is not easy to bend, is hidden in the air cavity cloth, is not exposed and is beautiful. The direct welding structure has the defects that a welding connection mode is adopted, when the inner container on one side is damaged, only the whole set of inner container can be replaced, the maintenance cost is high, the resources are wasted, and the environment is not protected. And the utility model discloses an aerify the connecting valve and combine the advantage of two kinds of current structures, realized that hidden structure, breather hose are difficult for buckling and can dismantle the effect of change maintenance.

As shown in fig. 1 to 5, the inflation connection valve includes three parts, namely a connection valve base 100, an inner container 200 and a base fixing structure 300, wherein the connection valve base 100 includes two groups, which are respectively symmetrically arranged and attached. Specifically, the connecting valve bases 100 are respectively disposed in two air chambers of the inflatable product, one of the connecting valve bases 100 is disposed in one of the air chambers of the inflatable product, and the other connecting valve base 100 is disposed in the other air chamber of the inflatable product. The two connecting valve bases 100 are closely fitted to form the inflation conduits of the two air chambers of the inflatable product. It is understood that one inflation connection valve is arranged between every two air cavities, and the number of the inflation connection valves of the inflatable product is determined according to the number of the air cavities of the inflatable product. For example, the backrest and the base of the inflatable sofa are provided with two air cavities, the existing connecting valve adopts the exposed ventilating bent nozzle to be communicated with the valves of the two air cavities, the structure of the ventilating bent nozzle can be seen from the outside, and the appearance is not beautiful enough. And the utility model discloses an aerify the connecting valve and set up respectively on the contact surface of base and back, the surface of every air cavity is provided with a set of connecting valve base 100, and connecting valve base 100 and inner bag 200 press from both sides the lateral wall of tight air cavity, and two connecting valve bases 100 play the effect of ventilating through base fixed knot structure 300 zonulae occludens. The utility model discloses an aerify connection valve structure can hide in the contact surface in two air cavitys, and is more secret, pleasing to the eye.

One side of two connecting valve bases 100 welds an inner bag 200 respectively, specifically, the both sides of inner bag 200 and connecting valve base 100 adopt the welding form to combine, also can adopt other connected modes such as bonding the utility model discloses do not describe. The inner container 200 and the connecting valve base 100 are attached to two sides of the cavity wall of the air cavity, and the inner container 200 is communicated with the connecting valve base 100 through the communication hole 110. It should be noted that the connecting valve base 100 is used as the position of air circulation of the air chamber, the connecting valve base 100 is tightly connected with the surface of the air chamber, and is not detachable, while the liner 200 is connected with the connecting valve base 100 from the other side of the air chamber, and the wall of the air chamber is between the connecting valve base 100 and the liner 200. The inner container 200 between the two air chambers is detachably connected through a connecting valve hose. When the liner 200 of one of the air chambers is damaged, the connecting valve hose between the two connecting valve bases 100 is firstly detached, then the liner 200 and the connecting valve base 110 of the air chamber to be maintained are detached, the new liner 200 and the new connecting valve base 110 are replaced, and then the connecting valve hose is remounted on the communicating hole 110 between the two connecting valve bases 110, so that the use can be continued. The cost of replacing the whole inflation connecting valve is reduced, resources are saved, the generation of plastic waste is reduced, and the inflation connecting valve is more environment-friendly. The connected mode between two air cavities of current generally adopts the undetachable connected mode, including but not limited to welded connection, welded connection and integrated into one piece connect etc. the inner bag 200 of two air cavities is connected the back and is not dismantled, when inner bag 200 damages the back, can only change whole gas connection valve, and the replacement cost is high, is unfavorable for the later maintenance.

The relative positions of the two connecting valve bases 100 are fixed by the base fixing structure 300, so that the connecting valve bases 100 between the two air cavities of the inflatable product are fixed, and the connecting valve bases 100 on the two sides are prevented from offsetting to influence the inflation effect. The existing air-breathing bent nozzle is mostly connected with the outside in an external mode, the air-breathing bent nozzle is exposed outside the connecting valve, and after the inflatable product is inflated, the air-breathing bent nozzle is exposed at the periphery, so that the appearance of the inflatable product is abrupt and unattractive. And in inflatable products such as inflatable tents and inflatable furniture, the curved mouth of ventilating that exposes also has certain potential safety hazard, and the easy mistake of touching in the use leads to the gas flow in the inflatable product to be obstructed, influences and uses experience.

The middle part of the connection valve base 100 of the present invention is extended with a communication hole 110, the communication hole 110 is disposed inside the connection valve base 100, and the two communication holes 110 of the two connection valve bases 100 are connected by a connection valve hose (not shown in the drawings), and the connection valve hose and the communication hole 110 are equivalent to a ventilation bent nozzle of the existing product. The communication hole 110 and the connection valve hose are built in, and only the connection valve base 100 on the outer side can be seen from the outside of the inflatable product, so that the related structures such as the communication hole 110 and the connection valve hose can be better hidden. Not only the outward appearance is more pleasing to the eye, and can reduce the probability that the user touched by mistake, and use experience is better. The two connecting valve bases 100 are connected through the base fixing structure 300, so that the two air cavities are communicated, and the connecting valve hose is arranged in the two connecting valve bases 100, so that the bending problem of the connecting valve hose in the actual use process can be effectively prevented. Effectively promote the efficiency and the anti-bending ability of aerifing of product. When the connection valve hose is connected with the communication hole 110, a sealing adhesive is applied to the periphery of the communication hole 110 in advance, the connection valve hose is sleeved with the communication hole 110, and a connection valve air-closing cover (not shown in the drawing) is sleeved on the periphery of the connection valve hose to reinforce the connection of the connection valve hose and the communication hole 110 so as to avoid air leakage.
