An independent airway type sports training inflatable cushion

Abstract

The invention provides a physical training inflating cushion with an independent air passage. The inflatable cushion comprises an inflating assembly, an air cushion sleeve and a liner structure arranged in the air cushion sleeve; the inflating assembly comprises an air pump, a controller and an air cavity which has several through holes and is connected with the air outlet end of the air pump, andan electromagnetic valve electrically connected with the controller is arranged at each through hole; each through hole is communicated with the air inlet end of one air inlet pipe; the liner structure comprises several adjustable air bags arranged in parallel; an air inlet is formed in each adjustable airbag, a check valve is arranged at each air inlet position, and each air inlet is communicated with the air outlet end of one air inlet pipe; an air outlet is further formed in each adjustable airbag, and the air outlets are communicated with an air outlet pipe; a pressure sensor is arrangedin each adjustable airbag, and the pressure sensor is electrically connected with the controller. All the airbags are mutually independent, the inflating and deflating speeds are high, and the comfortand safety of the inflating cushion are improved. The using is flexible, and the inflating cushion can be applicable to the requirements of different fields.

Description

technical field [0001] The invention relates to an inflatable cushion, in particular to an independent airway type inflatable cushion for physical training. Background technique [0002] In physical education classes or sports competitions, many times, because there is not enough space, the facilities used for sit-ups and high jump competitions need to be temporarily arranged. Thick mats are the most troublesome thing. If you use inflatable mats , which is convenient for transportation, saves time and manpower for layout and saves space, and can be used only after being charged to the specified air pressure. Inflatable cushions are favored by consumers because of their comfort, softness and warmth. Most of the general inflatable cushions adopt a design of inflatable and deflatable airbags. , to inflate the inside of the inflatable cushion body, so that the inflatable cushion body can be expanded to form a cushion or mattress, etc., for users to lie down or sit on, or open t...
