The electric pump may be reversible to provide for both inflation and deflation.
A multichannel air assembly (1000) for use with inflatable products with multiple inflatable chambers (C). Specifically, said multi-channel air assembly (1000) may be used to selectively inflate or deflate one or more chambers (C) of an inflatable product to varying pressures.
Air assemblies (1000,2000,3000,4000,5000) having an inflation, a deflation, and a closed state for use with inflatable products, such as air mattresses. Specifically, air assemblies (1000,2000,3000,4000,5000) can be changed manually by a user by operating a directional control valve (1033,2043,3033,4033,5001) to inflate, deflate, or close the inflatable product. The directional control valve (1033,2043,3033,4033,5001) may also activate a pump in the inflation and deflation states and deactivate the pump in the closed state.

A pool cleaner for use in a pool may include a housing, a driving assembly, a traction assembly, and a filtration assembly. The driving assembly may include an inlet conduit configured to receive pressurized water, an impeller in fluid communication with the inlet conduit, an outlet conduit in fluid communication with the impeller, and an outlet nozzle coupled to the outlet conduit and may be configured to eject the pressurized water upward from the housing and into the pool in a parallel or oblique ejection direction relative to a vertical axis. The traction assembly may be coupled to the impeller to drive the housing across the pool and the filtration assembly may be configured to filter water from the pool.
A hanging assembly is disclosed for use with a flow generating device that produces a current in a pool. The hanging assembly includes a back supporting plate coupled to a side supporting plate where a plate angle is formed between the back supporting plate and the side supporting plate. The plate angle is adjustable such that a current angle of the current relative to a sidewall of the pool can be varied based on user preferences.
An inflatable furniture design has a user-interfacing surface, such as the sleeping surface of an air mattress, which includes a breathable multilayer mesh which separates the user from the underlying air-impermeable sheet. The breathable mesh is made from a material such as 3D fabric, which is resiliently deformable while also allowing for airflow through and around the volume of the mesh material of the breathable interface material. When a person contacts the inflatable furniture, her or his body comes into direct contacts with the breathable mesh. The mesh then resiliently deforms such that airflow through and around the mesh is still permitted. This airflow allows heat and moisture from the user to dissipate through mesh of the breathable interface material. This, in turn, enhances the comfort of the breathable mesh, while also reducing the potential for the proliferation of bacteria and mites on the user-contacting surface.
