Description

Folding chair bloies

Technical Field

The invention relates to an article for daily use, in particular to a blowing folding chair.

Background

As a common daily product, the chair is used by almost everyone, and in order to facilitate carrying and save space, a plurality of chairs are made into foldable chairs, and the common chairs are wooden folding chairs and iron art folding chairs. The iron art folding chair generally adopts an iron art framework, and a cloth art or plastic chair is arranged on the iron art framework, so that the iron art folding chair is convenient to manufacture, low in cost and widely used. However, the existing common folding chair has poor air permeability, and in hot summer, because of high temperature, the skin of the folding chair is easy to adhere when the folding chair is seated, and the comfort is poor.

Disclosure of Invention

The invention overcomes the defects of poor air permeability of the folding chair and poor comfort when sitting on the folding chair, and provides the air blowing folding chair which has good air permeability, does not cause skin adhesion even sitting on the folding chair in hot summer and has good comfort.

In order to solve the technical problems, the invention adopts the following technical scheme: the utility model provides a folding chair bloies, includes the folding chair body, installs pad, the fan of blowing on the folding chair body, and the pad of blowing includes from last screen cloth, breather plate, the blotter that down sets gradually, sets up the clearance of ventilating between breather plate and the blotter, and the fan is bloied mouthful and is ventilated clearance intercommunication, sets up a plurality of blow holes that set up towards the screen cloth on the breather plate.

When the folding chair of blowing uses, the people sits on the pad of blowing, and fan work is to the clearance blast air of ventilating to blow to the screen cloth through the hole of blowing on the aeration plate, make on user's buttock and back are blown to wind, the people sits the gas permeability on the folding chair good, can weather wet back and buttock thoroughly, even sit the phenomenon that the skin adhesion can not appear on the folding chair in hot summer, the travelling comfort is good.
