Title: Fan with time indication

Description:
FIELD OF THE INVENTION  
      The present invention relates to fans, and in particular to a time indicator is combined to a fan. Thereby the fan has also the function of time indication. Thereby space is saved greatly. Besides, since the fan is faced to the user, the user can view the time directly.  
     BACKGROUND OF THE INVENTION  
      In the prior art, time indicator and fan are separated. However they are arranged at different areas. A great space is necessary. Generally, time indicators, such as alarm clocks, suspending clocks, or table clocks, etc., are arranged at a fixed position, such as beds, tables, or walls. Thus, generally, these clocks are not moved. If is often that the user cannot view the clocks easily and conveniently. Furthermore, when the user leaves the area, he (or she) cannot see the clock immediately.  
      Thereby there is an eager demand for a novel design which can improve the prior art defect.  
     SUMMARY OF THE INVENTION  
      Accordingly, the primary object of the present invention is to provide a fan with time indication, wherein a time indicator is combined to a fan. Thereby the fan has also the function of time indication. Thereby space is saved greatly. Besides, since the fan is faced to the user, the user can view the time directly.  
      To achieve above objects, the present invention provides a fan with time indication which comprises a fan having a base; a driving unit being installed on the base; a front end of the driving head having a rear net mask and a blade set capable of being driven by the driving unit; a front side of the blade set having a front net mask; the front net mask being combined with the rear net mask so as to enclose the blade set; the front net mask being separable from the rear net mask; the front net mask having a suspending hole by that the fan can be suspending from a wall; and a time indicator installed on the front net mask for displaying time. The time indicator is installed at a center of the front net mask; and the front net mask has a plurality of radiate net-like ribs which are corresponding to the scales of the time scales.  
      The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

     DETAILED DESCRIPTION OF THE INVENTION  
      In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.  
      Referring to FIGS.  1  to  8 , especially  FIGS. 1 and 2 , the fan with time indication of the present invention is illustrated. The present invention has the following elements.  
      A fan  1  has a base  10 . A driving unit  11  is installed on the base  10 . The driving unit  11  can swing at two sides. A front end of the driving head  11  has a rear net mask  12  and a blade set  13  capable of being driven by the driving unit  11 . A front side of the blade set  13  has a front net mask  14 . The front net mask  14  is combined with the rear net mask  12  so as to enclose the blade set  13 . The front net mask  14  is separable from the rear net mask  12 . The front net mask  14  has a suspending hole  15  by that the fan can be suspended from a wall.  
      A time indicator  2  is installed on the front net mask  14  for displaying time.  
      Referring to  FIGS. 3 and 4 , an iron retainer portion  16  at a central portion of the front net mask  14 . A front surface of the time indicator  2  has an hour hand  20 , a minute hand  21  and a time scale  22  for indicating time. A backside of the time indicator  2  has a suspending hole  23 , a support seat  24 , and a plurality of magnets  25 . The suspending hole  23  of the time indicator  2  can receive a nail at a wall. The support seat  24  is foldable and expandable. The plurality of magnets  25  can adhere to the retaining portion  16  so as to combine the time indicator  2  to the front net mask  14 . In other embodiments, the time indicator  2  can be embedded into, screwed to or buckled to the front net mask  14 , or by other ways.  
      Referring to  FIG. 5 , the front net mask  14  has a plurality of radiate net-like ribs  17  which are corresponding to the scales of the time scales  22  for viewing by users.  
      Referring to  FIG. 6 , when the front net mask  14  is detached from the fan  1 , it can be suspended from a wall by the suspending hole thereof. Thereby the front net mask  14  and the time indicator  2  are formed as a suspending clock.  
      Referring to  FIGS. 7 and 8 , the time indicator  2  can be separated from the front net mask  14 , the support seat  24  at the backside of the time indicator  2  can be expanded for suspending the time indicator  2  so as to be as a table clock or an alarm clock.  
      With reference to  FIG. 9 , the second preferred embodiment of the present invention is illustrated. The difference of this embodiment from the first embodiment is that a front surface of the time indicator  2  has a liquid crystal display screen  26  for displaying time.  
      Referring to  FIG. 10 , the third preferred embodiment of the present invention is illustrated. The difference of the third embodiment from the first embodiment is that the time indicator  2  has a battery set  27  and a control circuit  28 . The battery set  27  serves to supply power to the time indicator  2 . The control circuit  28  serves to control and drive the operation of the time indicator  2  and is connected to the power source  18  of the fan  1 . The power of the power supply is stored in the battery set  27 . A power generator  3  is installed between the fan  1  and the time indicator  2  for converting the dynamic power from the operation of fan  1  to the electric power which is stored in the battery set  27  by the control of the control circuit  28 .  
      With reference to  FIG. 11 , the fourth preferred embodiment of the present invention is illustrated. The fourth embodiment is identical to the first embodiment except that the net ribs  17  on the front net mask  14  has numbers  19  corresponding to the time scales  22 . The hour hand  20  and minute hand  21  extend out of the time indicator  2  so that the user can clearly view the indication of time.  
      In the present invention, the time indicator  2  is combined to a fan  1 . Thereby the fan  1  has also the function of time indication. Thereby space is saved greatly. Besides, since the fan is faced to the user, the user can view the time directly.  
      The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
