[0027] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0028] See attached Figures 1 to 3 , an inflatable seat cushion, comprising: a seat cushion component, a cushion component and a detachable pipe 320.

[0029] Among them, the backrest component includes a first airbag 110 that maintains a predetermined shape after inflation, an air inlet 120 and an air outlet 130 arranged on the first airbag 110, and a cushion 140 fixed to one side of the first airbag 110 in a detachable manner; the cushion body component includes a second airbag 210 connected to the first airbag 110 through a detachable pipe 320, at least one vent 220 arranged on the second airbag 210, and a bottom pad 230 fixed to the upper part of the second airbag 210 in a detachable manner and connected to the bottom of the cushion 140 through a connecting part.

[0030] When used at home, there is no need to configure the second airbag 210, and the overall effect is similar to that of the company's prior application (an adjustable inflatable cushion 140, announcement number: CN 220045358 U); when used outdoors, the first airbag 110 is in the shape of a triangular prism or a triangular prism after inflation; the second airbag 210 is in the shape of a cuboid or a cuboid after inflation. The second airbag 210 can play the role of overall support, and can provide more uniform and comprehensive support for the user's back and waist, and provide better ergonomic support. The user can directly half-lie on the bottom cushion 230 to reduce waist and back fatigue and discomfort caused by long-term sitting, and adapt to different usage scenarios and needs.

[0031] In further embodiments, see the attached Figure 2 , the outlet 130 and the vent 220 are provided with a quick-insert female connector 310. The detachable pipe 320 includes a hose 321 and quick-insert male connectors 322 arranged at both ends of the hose 321 and matching the quick-insert female connector 310. The quick-insert female connector 310 and the quick-insert male connector 322 are commercially available products, and their structures are not specifically introduced here, but it is pointed out that when the quick-insert female connector 310 is disconnected from the quick-insert male connector 322, the quick-insert female connector 310 has a flow cutoff function to form a circuit breaker; when the quick-insert female connector 310 is connected to the quick-insert male connector 322, the quick-insert female connector 310 and the quick-insert male connector 322 are connected to form a passage. The coordinated use of the quick-insert female connector 310 and the quick-insert male connector 322 not only facilitates users to quickly inflate and deflate, but also automatically closes when not connected, avoiding accidental gas leakage, and improving the convenience and safety of the inflatable seat cushion.

[0032] In a further embodiment, the first airbag 110 is fixedly mounted on the back of the cushion 140 by Velcro; the second airbag 210 is fixedly mounted on the bottom pad 230 and / or the bottom surface of the first airbag 110 by Velcro. Velcro is preferably Velcro, which is also a kind of Velcro and may be superior to some common Velcro on the market in terms of durability, wear resistance and adhesion retention, and can withstand more opening and closing cycles without losing viscosity.

[0033] In further embodiments, see the attached Figure 3 Since the first airbag 110 and the second airbag 210 are involved in this embodiment, the volume is larger when stored. In order to meet the storage requirements, a receiving groove 141 is formed on the back of the cushion 140, and a locking assembly is arranged between the cushion 140 and the bottom pad 230. The locking assembly includes: two zippers 142 respectively arranged on the back of the cushion 140 and the outer edge of the bottom pad 230, and at least one sliding locking member 143 arranged between the two zippers 142. The cushion 140 and the bottom pad 230 are both made of textile elastic materials and have a certain amount of deformation. In the stored state, the first airbag 110 and the second airbag 210 are both in a deflated state and stored in the receiving groove 141, and the cushion 140 and the bottom pad 230 are closed by the locking assembly. The volume of the bed pillow after storage is approximately equal to the volume of the cushion 140.

[0034] In a further embodiment, the air inlet 120 is equipped with an electric inflator 121. The electric inflator 121 automatically moves the power source. Specifically, the electric inflator 121 is a small fan with an automatic mobile power source. The user does not need an external power source or manual pumping, which greatly improves the flexibility and immediacy of use and meets the needs of users for outdoor activities.

[0035] To facilitate understanding of the technical solution of the inflatable seat cushion, a brief description is given of its working principle: during the deployment process, the locking assembly is opened to take out the first airbag 110, the second airbag 210 and the detachable pipe 320, the first airbag 110 is connected to the second airbag 210 through the detachable pipe 320, the electric inflation device 121 is turned on to inflate the first airbag 110 and the second airbag 210 at the same time, and after the first airbag 110 and the second airbag 210 are fully deployed, the two ends of the detachable pipe 320 are pulled out at the same time, the air outlet 130 and the air vent 220 are closed, and finally the back cushion 140 and the bottom pad 230 are installed to achieve the deployment of the inflatable seat cushion.

[0036] During the storage process, the back cushion 140 and the bottom cushion 230 are first removed, and then one end of the detachable pipe 320 is inserted into the first airbag 110 or the second airbag 210, so that the first airbag 110 or the second airbag 210 is connected to the outside world to achieve pressure relief and deflation of the first airbag 110 or the second airbag 210. Finally, the first airbag 110, the second airbag 210 and the detachable pipe 320 are stored in the back accommodating groove 141, and the back cushion 140 and the bottom cushion 230 are closed by the locking assembly to achieve the storage of the inflatable seat cushion.

[0037] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
