Abstract:
A computer mouse with liquid ornaments is comprised of a main body of mouse and an ornament disposed on the main body, in which the ornament may contain a mere liquid or a floating-article-contained liquid. When the main body is under operation, the liquid and floating article will flow or drift to present a sightly vision to heighten people&#39;s interest and delight in operating the mouse. Moreover, the ornament is replaceable depending on personal favor.

Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     This invention relates generally to the structure of a computer mouse, specifically to a computer mouse with detachable liquid ornaments.  
         [0003]     2. The Prior Arts  
         [0004]     A computer mouse is one of the peripherals of computer used for controlling a cursor on screen, and furthermore, for executing a graphic file or choosing options.  
         [0005]     For the sake of attracting consumers, some makers endeavored in adding wheels to a conventional computer mouse for making operation easily, some others engaged in introducing an optical mouse to substitute for that of a roller style cursor-control manner in order to avoid bringing the dust of a slide pad or desktop into the mouse, yet some others made efforts in wireless design of mouse for releasing the bondage of conventional wire-transmission. Nevertheless, however, all the mentioned computer mice work on the basis of the same principle for cursor control in the way a conventional mouse used to do.  
         [0006]     For making a conventional computer mouse look more active in configuration, a liquid ornament is added to the tail end of mouse as disclosed recently in U.S. Pat. No. 6,380,926B1—“Computer mouse” and Taiwan patent No. 542380—“Mouse housing with liquid ornament”. However, in either patent, the added liquid ornament is inseparably fixed or glued to the main body of the computer mouse, hence, processing is rather difficult and replacement of the ornament is impossible.  
       SUMMARY OF THE INVENTION  
       [0007]     For dissolving abovementioned defects, the primary object of this invention is to provide a computer mouse with detachable liquid ornaments, in which the ornaments could be dismounted easily to hence facilitate updating of the printed pattern on the mouse, whenever desired.  
         [0008]     In order to realize the foregoing object, the computer mouse with liquid ornaments is comprised of a main body of mouse and an ornament connectively mounted on the main body, in which the bottom end of the main body is a base, on which an inner casing is arranged. A junction area is arranged on two sides of the inner casing and along an edge of the base for connectively mounting the ornament, where a positioning portion is formed on a wall of the edge of the base in the junction area. An assembling space for accommodating the ornament is reserved between the rear end of the inner casing and the base, and the ornament is composed of a casing and a bottom cover, in which a roof portion, which is formed at the front end of the casing for covering on the inner casing, is provided on two sides with a connecting portion for connectively mounting the roof portion to the positioning portion. The roof portion abuts upon a sealing space, which allows a liquid and/or a floating article to enter through an entrance and sealed by the bottom cover. A through hole penetrating through the base is disposed in the bottom end of the base and in the assembling space, and a plurality of connecting portions is provided to the inner wall of the through hole for connectively combining with the ornament. The bottom cover is provided with a protruding portion on a lateral face thereof to be sleeve-jointed with the through hole, in which a positioning portion is further provided to the protruding portion for connectively combining with the connecting portions to thereby facilitate mounting or dismounting the ornament on or from the main body of mouse.  
         [0009]     For more detailed information regarding advantages or features of this invention, at least an example of preferred embodiment will be described below with reference to the annexed drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0018]      FIG. 1  is a schematic three-dimensional view of appearance of a computer mouse with detachable liquid ornaments of this invention, while  FIG. 2-1  and  FIG. 2-2  are schematic exploded and partially enlarged views respectively of  FIG. 1 . As shown in figures, the computer mouse with liquid ornaments of this invention is comprised of a main body  1  of mouse and an ornament  2 , in which the ornament  2  is a liquid-contained ornament to be mounted on the main body  1  for promoting image of the computer mouse, interest of using it, and easiness of replacement.  
         [0019]     The bottom end of the main body  1  is a base  11 , on which a pair of symmetrical keys  12 , 13  is disposed. In the space between the keys  12 , 13  and the base  11 , an inner casing  14  is arranged, and in the space between the inner casing  14  and the base  11 , a circuit board (not shown) for processing operation signals of the main body  1  is inserted. Moreover, a junction area  15  is arranged on two sides of the inner casing  14  and along an edge of the base  11  for connectively mounting the ornament  2 , where a positioning portion  16  is formed on a wall of the edge of the base  11  in the junction area  15 . Besides, an assembling space  17  for accommodating the ornament  2  is reserved between the rear end of the inner casing  14  and the base  11 , in which a through hole  18  penetrating through the base  11  is disposed in the bottom end of the base  11  and in the assembling space  17 . A plurality of connecting portions  19  is provided to the inner wall of the through hole  18  for connectively combining with the ornament  2 .  
         [0020]     The ornament  2  is made of a transparent plastic material, and comprises a casing  21  and a bottom cover  22 . A roof portion  23 , which is formed at the front end of the casing  21  for covering on the inner casing  14 , is provided on two sides with a connecting portion  24  for connectively mounting the roof portion  23  to the positioning portion  16 . The roof portion  23  abuts upon a sealing space  25 , which allows a liquid and/or a floating article to enter through an entrance  26  to be sealed by the bottom cover  22 . The bottom cover  22  has a protruding portion  27  on a lateral face thereof to be sleeve-jointed with the through hole  18 , in which a positioning portion  28  is further provided to the protruding portion  27  for connectively combining with the connecting portions  19  to thereby mount or dismount the ornament  2  on or from the main body  1  of mouse.  
         [0021]     Please refer this time to  FIGS. 3 and 4 , in which  FIG. 3  is a cutaway sectional view taken along line A-A in  FIG. 1 ; and  FIG. 4  is a cutaway sectional view taken along line B-B in the same figure. As shown in the figures, a liquid or a floating-article-contained liquid is poured into the sealing space  25  in the casing  21  of the ornament  2 , then, the entrance  26  is sealed with the bottom cover  22 .  
         [0022]     After the liquid and the floating article are retained inside the ornament  2 , by means of connectively combining the connecting portion  24  and the positioning portion  28  of the ornament  2  with the positioning portion  16  and the connecting portion  19  of the main body  1 , the ornament  2  can be assembled on or disassembled from the main body  1  of mouse, and it is possible for a user to replace the ornament  2  in different patterns.  
         [0023]      FIG. 5  is a schematic view showing an embodiment of this invention. As shown in  FIG. 5 , a liquid  3  to be poured into the ornament  2  of this invention could be a liquid of single species or two species indissoluble to each other, while a floating article  4  floated on the liquid  3  could be a three-dimensional pattern in diversified configurations. When a user is operating the main body  1  of mouse, the liquid  3  inside the ornament  2  will flow subsequently, and so does the floating article  4  therein accordingly.  
         [0024]      FIG. 6  is a schematic view showing another embodiment of this invention. As indicated in  FIG. 6 , various patterns, such as trademarks, could be printed or stuck on the surface of the inner casing  14  of the main body  1  and protected by the roof portion  23  at the front end of the casing  21  of the ornament  2  against scratch, etc. Also, the floating article  4  may be made in form of a three-dimensional pattern of trademark as a free gift to be drifted on the liquid  3  in a commercial event.  
         [0025]     In addition to the merit of this invention for easy mounting or dismounting the detachable ornament  2  on or from the main body  1  of mouse, a user may replace it by himself without difficulty, and it is very convenient for people to print a trademark and stick it onto the ornament  2 .  
         [0026]     In the above described, at least one preferred embodiment has been described in detail with reference to the drawings annexed, and it is apparent that numerous changes or modifications may be made without departing from the true spirit and scope thereof, as set forth in the claims below.
