And the upper and lower hub bodies are provided with a plurality of corresponding grooves for the fixing portions of the respective blades, and a tooth portion is respectively disposed on the inner side surface of the groove; the blade system is provided The utility model has a conical fixing portion, so that the fixing portion can be sandwiched in a corresponding shape of the inner lower jaw body, and the conical bottom edge of the fixing portion is provided with a toothed shape and can respectively be respectively The teeth of the upper and lower hub bodies are relatively meshed, thereby making the blades clamped in the hub have better stability to avoid sway or noise, and facilitating the assembly or angle adjustment of the blades. One purpose is to provide an impeller structure of a blower. The same indicator scale is provided on the bottom surface of one of the fixing portions of the blade, and the indicator scale can be used to identify each blade when installing each blade. The blade can be easily positioned in the same - Installation angle, borrowing the efficiency and accuracy of the blade. Another object of the present invention is to provide an impeller of a blower, wherein the blade of the impeller is designed to be symmetrically shaped, and the impeller is rotated by the impeller to rotate forward or reverse to achieve a two-way air supply operation. Convenience and Saving Operation Costs and Embodiments [Embodiment] In order to make the present invention more clear and detailed, the structure and the technology of the present invention are combined with the following diagrams. 4 1334899 t » · Please refer to FIG. 1 to FIG. As shown, the blower 1 of the present invention comprises a cylindrical outer casing 10, which is a double-shell structure having inner and outer layers, and can be formed by using galvanized steel sheets and galvanized punched steel sheets or the like. The sound absorbing material may be filled between the outer layer and the inner layer, and the sound absorbing material may be made of cotton material; the front side 11 of the outer box 10 is provided with an air inlet 12, and the rear side 13 is provided with an air outlet 14; 10 at least one bracket 15 can be disposed at an appropriate place, so that the blower 1 can be suspended by the bracket 15 and used for hanging on the ceiling; and the air inlet 12 and the air outlet 14 are respectively provided with a safety guard. The net 20 can be woven by a metal wire to form a stainless steel spot welded wire such as a turtle net or a square shape, so as to prevent foreign matter such as birds from inadvertently invading the blower 1 and the air inlet 12 and the air outlet 14 of the blower 1 Add a security protection effect. Further, a flow guiding muffler cone 30 is further disposed between the air inlet 12 and the inner side of the air outlet 14 and the impeller 40, and the guiding muffling cone 30 is a double-layer structure having inner and outer layers, which can be galvanized steel plate and plated. The zinc punched steel plate or the like plate is formed, and the sound absorbing material can be filled between the outer layer and the inner layer, and the sound absorbing material can be constructed by using the cotton material to avoid the position of the blower or the center position of the blower 1 when the airflow of the blower 1 inlet/outlet flows. The effect is that the airflow cannot be smoothly passed and the running noise of the blower 1 is reduced. An inner portion of the cylindrical outer casing 10 is provided with an impeller 40. The impeller 40 includes an upper hub 41, a lower hub 42 and a plurality of blades 43. The upper hub 41 and the lower hub 42 are Correspondingly, a complete hub body can be locked correspondingly, and a plurality of upper and lower corresponding grooves 411 are arranged at equal angles and radially arranged at the inner near outer edge of the upper hub body 41 and the lower hub body 42, respectively, and each groove 411 is also provided with a corresponding opening 413; the upper and lower corresponding grooves 411 are used for closely clamping the fixing portion 431 of the blade 43, and the blade portion 435 of the blade 43 can be outwardly protruded from the opening 413; the upper and lower body portions are further An inner surface of the central axis of the proximal hub of the groove 411 of 41 and 42 is respectively provided with an annular tooth portion 412. 5 1334899 The center of the lower hub 42 is imaginary. ^ A motor 50 drives the impeller 4 to rotate. The 'S j4 is connected to the inside of the cylindrical outer casing 10 to lock the position of the motor 50 and increase Its stability. The plurality of supports 16 are fixed to the blade 43 to include a blade adjacent 151 〜 〜 the fixed portion is a truncated-fixed portion, wherein the concave sample 411 (four), # = ΐ corresponds to the upper and lower valleys 41, 42, the groove 411 is green, so that the truncated cone shape = the groove 411 of the upper and lower hub bodies 41, 42. The ▽社田紧4 fits around the bottom edge and has a ring-shaped outer shape cone The 432 can be engaged with the upper and lower housings 4 in a toothed shape. When the pair of teeth 412 in the groove 411 are assembled, the fixing portion 431 of the blade 43 can be correspondingly, and the concave portion (41) of the 41 and 42 can be made to be the same as that of the upper and lower hub bodies 41 and 42 simultaneously. The external type locks the firmware such as the bolt 45 and the nut 46#φ73| I & relative engagement, and then up, down _, 42 Ξ = ί through the upper and lower hub body lock, so that the 〇 structure blade 43 can be firmly locked into an impeller and the fixed part of each blade 43 One of the bottom faces of the 431 = indicating scale 434' is provided for mounting the respective leaflets 434 to identify the safety of the respective blades 43, and the shuttles are not at the same mounting angle, so that the blades 43 can be easily characterized. In order to improve the efficiency of the installation of the blade 43 and the accurate shape of the f-piece 43 of the impeller 4Q, as shown in Figs. 2 and 3, the installation is relatively simple, and the curtain pen is only smashed, and the two tails are 436 thin. The middle section is guilty, the wide line grabs the I# piece 4, and the symmetrical blade 43 is used to match the blower motor 5 〇 # Λ γ 孓 孓 孓 又 又 又 又 又 又 又 , , , , 华 华 华 华 华 华 华 华 华 华 华 华 华 华 华The change of the movement (/reverse) = the result of the program can be achieved in the forward or reverse rotation of the wind can be achieved by the above structure 'and the actual laboratory test is true, the invention of the send 6 1334899 • * · fan 1 indeed The stability of the blade 43 of the impeller 40 can be improved, the running cost can be saved, and the convenience, rapidity and accuracy of the overall blade 43 adjustment operation and the good use effect of the two-way air supply can be achieved, so as to avoid the stability of the fan of the conventional blower. Good, complicated correction work and single air supply direction.
