BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates generally to a blow drying tool, especially, to a blow drying mechanism for drying a plate-like workpiece. 
         [0003]    2. Description of Related Art 
         [0004]    During many manufacturing processes, products need to be cleaned one or more times. If the products are not dried effectively after cleaning, subsequent manufacturing steps may be affected negatively. Products not suitable to be dried by heating methods, the products may be blow dried. During drying, a nozzle connected to pressurized air directs airflow to surfaces of the products. However, the pressurized air may not strike all parts of a surface at the same pressure and may leave watermarks on surfaces of the products, which may in turn affects appearances and performances of the product negatively. 
         [0005]    Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       [0012]    Referring to  FIGS. 1 and 2 , a first embodiment of a blow drying mechanism  10  is communicated with a pressurized air source (not shown), such that the blow drying mechanism  10  is used to dry a plate-like member (not shown) with the pressurized air. The blow drying mechanism  10  has a substantially rectangular, plate-like structure, and includes a bottom wall  11 , a top wall  21  opposite to the bottom wall  11 , an air inlet wall  31 , a first sidewall  41 , an air outlet wall  51  opposite to the air inlet wall  31 , and a second sidewall  61  opposite to the first sidewall  41 . The air inlet wall  31 , the first sidewall  41 , the air outlet wall  51 , and the second sidewall  61  extend perpendicularly from a periphery of the bottom wall  11  to the top wall  21 , and connect with each other in that order. 
         [0013]    Also referring to  FIGS. 3 and 4 , a plurality of inlets  311  are defined in the air inlet wall  31 . The plurality of inlets  311  are evenly spaced between each other. An extending direction of each of the plurality of inlets  311  is perpendicular to the air outlet wall  51 . The plurality of inlets  311  are connected to an air outlet of the pressurized air source. In the first embodiment, the plurality of inlets  311  comprise five inlets. A cross section of each of the plurality of inlets  311  taken perpendicular to the extending direction of the plurality of inlets  311  is substantially circular. In alternative embodiments, the number of the plurality of inlets  311  can be changed according to need such as to accommodate work pieces of different size and shape. 
         [0014]    An outlet  511  is defined in the air outlet wall  51 , and is communicated with all of the plurality of inlets  311 . The outlet  511  is an elongated slot, and extends from one end of the air outlet wall  51  to the other end of the air outlet wall  51 . A length of the outlet  511  is greater than the sum of diameters of the plurality of inlets  311 . In the first embodiment, the outlet  511  is substantially a rectangular slot. A width of the outlet  511  along a direction perpendicular to the bottom wall  11  is less than diameter of each of the plurality of inlets  311 , to maintain a desired air pressure. 
         [0015]    In alternative embodiments, the inlet  311  can be defined in the bottom wall  11 , the top wall  21 , the first sidewall  41 , or the second sidewall  61 . 
         [0016]    When blow drying a plate-like member with the blow drying mechanism  10 , the plate-like member is placed opposite to the outlet  511 , and a predetermined angle is formed between the plate-like member and the air outlet wall  51 , such as 30 degrees or 60 degrees. Because the outlet  511  is an elongated slot, the pressurized air strikes linearly to the plate-like member, and diffuses along a surface of the plate-like member at the same pressure. Thus, the surface of the plate-like member can be dried completely and effectively without leaving watermarks. The blow drying mechanism  10  has a simple structure with a low cost. 
         [0017]    Referring to  FIG. 5 , a second embodiment of a blow drying mechanism  20  has a similar structure to the first embodiment of the blow drying mechanism  10 . However, a plurality of outlets  5011  are defined in an air outlet wall  501 , a number of the plurality of outlets  5011  is the same as that of inlets  3011  defined in an air inlet wall  301 , and each of the plurality of outlets  5011  is communicated with each of the inlets  3011 . A length of each of the plurality of outlets  5011  is greater than diameter of each of the inlets  3011 . A width of each of the plurality of outlets  5011  along a direction perpendicular to a bottom wall  101  is less than diameter of each of the inlets  3011 . Because each of the plurality of outlets  5011  corresponds to one of the inlets  3011 , when drying the plate-like member, a desired air pressure is easy to maintain, and the plate-like member can be dried effectively. 
         [0018]    It is to be understood, however, that even through numerous characteristics and advantages of the disclosure have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
