Side portion 112 returns to the second wind pushing mechanism 150, forms self-cycle structure.Compared with air curtain of the prior art, the present invention carries
The self-loopa air curtain 100 of confession as a result of be sequentially connected installation portion 114, first side portion 111, backflow portion 113 and
Dual side-edge portion 112, so the formation of steady air flow curtain can be realized, and steady air flow can be returned to along backflow portion 113 into
The position of gas, the generation in air-flow cavity is avoided, it is practical, it is cost-effective, make air curtain system 10 more safe and efficient, completely cut off
Effect is more preferable, is liked by user.
The preferred embodiments of the present invention are these are only, are not intended to limit the invention, for those skilled in the art
For member, the present invention can have various modifications and variations.Any modification within the spirit and principles of the invention, being made,
Equivalent substitution, improvement etc., should be included in the scope of the protection.
