Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 3, the light composite blade of the present invention includes a blade shell and a foam core 1 disposed in the blade shell, wherein the foam core 1 supports the blade shell. Specifically, the blade shell includes two wood pieces 2, and the two wood pieces 2 are adhered to the surface of the foam core 1 by an adhesive such as epoxy resin. According to the scheme, the wood chips 2 are bonded and compounded on the surface of the foam core 1, so that the blade has the advantages of light weight and strong structural rigidity, and does not crack, deform or age, compared with the existing solid wood blade, the blade saves materials, has low formaldehyde release amount, is easy to manufacture, is beneficial to improving the processing efficiency, has low manufacturing cost, does not lose the high-grade texture of the solid wood blade, and is fashionable and attractive in appearance; the foam core 1 is arranged in the hollow blade shell, so that the temperature difference resistance of the blade is improved to some extent, and the blade has a certain warm-keeping function, is firm and durable, and prolongs the service life of the ventilation window to some extent.

In order to improve the structural rigidity of the blade, glass fiber cloth 3 is arranged between each wood chip 2 and the surface of the foam core 1, the glass fiber cloth 3 is respectively bonded with the foam core 1 and the wood chips 2 through epoxy adhesives, and the connection strength of the wood chips 2 and the foam core 1 is improved to a certain extent. The central axis of the glass fiber cloth 3 in the length direction is on the same horizontal plane with the central axis of the foam core 1 in the length direction. The length and the width of the glass fiber cloth 3 are determined according to the width and the thickness of the blade, preferably, the thickness of the glass fiber cloth 3 is 0.1-0.3 mm, and the glass fiber cloth 3 in the thickness range can not only enhance the structural rigidity of the blade, but also can not increase the whole weight of the blade.

The blade shell can be formed by directly enclosing two arc-shaped wood pieces 2, and also can be formed by two wood pieces 2 and two side sealing strips 4 connected with the upper side and the lower side of the two wood pieces 2. As a preferred embodiment, the vane shell of the present invention further comprises two side seals 4, wherein the upper and lower sides of the two wood pieces 2 are respectively connected by one side seal 4, the side seals 4 are arranged along the axial direction of the two wood pieces 2 and are fixedly connected with the upper and lower ends of the two wood pieces 2, and the side seals 4 are bonded with the foam core 1.
