New description: [New technical field] This creation is about a blade structure, especially a blade structure used for a ceiling fan. [Prior Art] The blade (10) used in the current market ceiling fan (shown in Figure 1) is composed of two low-density slabs (11) that are subject to environmental factors when used for a long time ( If the humidity or temperature changes affect the bending of the low-density layer (11) of the blade (10), it will increase the number of replacements of the blade (10), thereby increasing the cost burden. In view of this, the creators of this case have been carefully designed and designed with many years of experience. After many discussions and trials of sample tests and multiple corrections, a blade structure was developed. [New content] The purpose of the present invention is to provide structural reinforcement by the blade through the high-density layer to match the low-density layer; for the above purpose, the blade comprises a high-density layer and a low-density layer; wherein the blade The bonding surface of the high-density slab layer is fixed corresponding to the bonding surface of the low-density slab layer of the blade, thereby: 5 M317501 The blade is designed to pass through the structure of the high-density slab layer having a density greater than that of the low-density slab layer The high-density slab structure strengthens the low-density slab structure, so that the blade does not bend and deform easily and maintains the blade air guiding structure, thereby eliminating the number of blade replacements and reducing the cost burden. [Embodiment] The techniques, means and other functions of the present invention are described in detail with reference to the accompanying drawings, and the above-mentioned objects, features and other advantages are believed to be In-depth and specific understanding; please refer to Figure 2, the original blade (20) comprises a high-density layer (21) and a low-density layer (22); the high-density layer (21) is dense a plate or a plywood, the high-density ply (21)-side has a joint surface (211); the low-density ply (22) is a splint or a wood board, and the low-density ply (22) has a joint surface on one side (221); the shape of the high-density layer (21) of the blade (20) corresponds to the shape of the low-density layer (22) of the blade (20), and the density of the high-density layer (21) of the blade (20) is greater than The structural density of the low-density layer (22) of the blade (20), the bonding surface (211) of the high-density layer (21) and the bonding surface (221) of the low-density layer (22) are correspondingly fixed, The blade (20) strengthens the structure of the low-density layer (22) through the high-density layer (21) structure, so that the blade (20) does not Easy to bend 6 M317501 The deformation of the blade further extends the service life of the blade (20); in addition, the blade (2〇) is under the existing blade structure of the high-density layer (21) and the low-density layer (22). A low-density layer (22,) with a joint surface (221') (see also Figures 4 and 5) is formed into a three-layer structure; An overview of the relationship between the relative elements of the various components and their construction. In order to clearly explain the operation and efficacy of this creation, please also refer to Figure 2 to Figure 3: The joint surface (211) of the blade (20) high-density layer (21) corresponds to the blade (20) The bonding surface (221) of the low-density layer (22) is fixed, so that the blade (20) has a structural density greater than that of the low-density layer (22) I by the structure density of the low-density layer (22). Having the blade (2〇) strengthen the structure of the low-density layer (22) through the high-density layer (21) structure, so that the blade (2〇) does not bend easily and maintains the blade (20) air guiding structure, and further Reduce the number of blade (2〇) replacements and reduce the cost burden. In summary, the blade of the present invention comprises a high-density slab and a low-density slab; wherein the slab is designed such that the density of the high-density slab is greater than the density of the low-density slab, so that the high-density slab The layer and the low-density layer correspondingly reinforced and strengthened the blade structure' so that the blade is not easily bent and deformed, and the blade life is prolonged by the 7 M317501, and the blade wind flow efficiency is maintained; therefore, the creation has "industrial availability" It should be undoubtedly, in addition to this, the feature technology exposed in the embodiment of this case has not been seen in the publications before the application, nor has it been used publicly, not only has the fact that the above-mentioned effects are enhanced, but also must not be neglected. The additional effect is that the "novelty" and "progressiveness" of this creation have been in compliance with the patent regulations', and the application for a new type of patent has been filed according to law, and it is prayed for review and early grant of patents.
