Embodiment Construction
[0059]It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
[0060] like Figures 1 to 5 as well as Figure 8 to Figure 14 As shown, the inflating and deflating device of the present invention includes an inflator 6, an air path reversing valve 1 communicating with the inflator 6, and a housing 8, wherein the air path reversing valve 1 and the inflator 6 are both Installed in the housing 8, the air path reversing valve 1 has an inflation air path for air bag inflation and a deflation air path for air bag deflation, and the air pump 6 is changed through the air path. The air path switching between the inflation air path and the deflation air path in the valve 1 realizes the inflation or deflation of the air bag.

The invention discloses an inflation and deflation device. The inflation and deflation device comprises an inflator pump and an air path reversing valve communicated with the inflator pump, an inflation air path and a deflation air path which can be switched with each other are arranged in the air path reversing valve, the inflator pump inflates or deflates through air path switching in the air path reversing valve, the inflator pump comprises a piston cylinder, a driving assembly, a first elastic sealing part and a second elastic sealing part, the piston cylinder comprises a cylinder body, apiston and a piston rod, and the piston is provided with an air passage; the driving assembly is used for driving the piston to move in a reciprocating manner; the first elastic sealing part has an outward expanding state for opening the air passage when the piston cylinder sucks air and a closing state for closing the air passage when the piston cylinder exhausts air; and the second elastic sealing part has a closed state for closing the cylinder body air outlet when the piston cylinder sucks air and an open state for opening the cylinder body air outlet when the piston cylinder exhausts air.The air path reversing valve is used in cooperation with the inflator pump, the air bag can be inflated and deflated by switching the inflation air path and the deflation air path, the cost can be controlled, and the inflation and deflation device has the advantages of being convenient to operate and flexible to use.
Description
technical field [0001] The invention relates to the technical field of inflation equipment, in particular to an inflation and deflation device capable of both inflation and deflation. Background technique [0002] The portable inflatable water platform has the characteristics of light weight, multi-function, easy disassembly and storage, and is widely used in water leisure and entertainment, water sports activities, wharf engineering, water commercial performances and other projects. [0003] The above-mentioned portable inflatable water platform includes a carrying platform and an air bag connected with the carrying platform to provide buoyancy. When using the portable inflatable water platform, the air bag needs to be inflated. When carrying and storing the portable inflatable water platform The gas in the air bag needs to be released. [0004] At present, in order to inflate and deflate the above-mentioned airbags, it is often necessary to be equipped with different equi...
