When switching on the on/offswitch 122 with the hand H, peppercorns are ground by the grinding mechanism intopepper powder 70 for application. This structure of pepper mill is still not satisfactory in function. One drawback of this structure of pepper mill is that residual pepper powder tends to fall out of the bottom dispensing port of the bottom housing when putting the pepper mill on a flat surface. Another drawback of this structure of pepper mill is that the top housing must be opened from the intermediate shell so that peppercorns can be put in the bottom housing for grinding. Further, when cleaning the pepper mill, the parts must be detached from one another. - The present invention has been accomplished to provide a pepper mill, which eliminates the aforesaid drawbacks. It is one object of the present invention to provide a pepper mill, which has its pepper powder dispensing port disposed at the top side. It is another object of the present invention to provide a pepper mill, which enables the user to feed peppercorns for grinding conveniently. It is still another object of the present invention to provide a pepper mill, which enables the user to clean the grinding mechanism conveniently. It is still another object of the present invention to provide a pepper mill, which well protects the internal grinding mechanism against outside dust. According to one aspect of the present invention, the pepper mill includes a housing holding a driving mechanism and an output shaft, a top cover shell covered on the housing and defining with the housing a peppercorn chamber, the top cover shell having a threaded top neck, a grinding mechanism provided in the top cover shell and driven by the output shaft to grind peppercorns into powder, and a screw cap threaded onto the threaded top neck of the housing for output of ground pepper powder. According to another aspect of the present invention, the top cover shell has a peppercorn inlet through which peppercorns are inserted into the peppercorn chamber for further grinding. According to still another aspect of the present invention, a bracket is provided inside the top cover shell and defining with the threaded top neck of the top cover shell a grinding chamber within which the grinding mechanism is driven to grind peppercorns into powder. According to still another aspect of the present invention, a transparent swivel frame is pivoted to the top cover shell and adapted to close/open the peppercorn inlet. According to still another aspect of the present invention, a protective cap is adapted to close the screw cap.
- FIG. 1 is an elevational view of a pepper mill according to the prior art.
- FIG. 2 is an elevational of a pepper mill according to the preferred embodiment of the present invention.
- FIG. 3 is an exploded view, partially cutaway, of the pepper mill according to the preferred embodiment of the present invention.
- FIG. 4 is a sectional view of the pepper mill according to the preferred embodiment of the present invention.
- FIG. 5 is an applied view of the present invention, showing pepper powder shaken out of the pepper mill.
- Referring to FIGS. from2 through 4, a pepper mill is shown comprising a
housing 50, atop cover shell 30, anouter grinding member 64, aninner grinding member 62, aswivel frame 40, ascrew cap 32, and aprotective cap 20. Thehousing 50 is a cylindrical structure convenient for holding by hand, comprising a driving mechanism (not shown) mounted on the inside, anoutput shaft 54 coupled to the driving mechanism and extended out of a top center through hole (not shown), and an on/offswitch 52 provided at the periphery at a suitable location. The driving mechanism can be a manual driving mechanism operated by hand to rotate theoutput shaft 54. Alternatively, the driving mechanism can be an electricity-driven driving mechanism. According to the present preferred embodiment of the present invention, the driving mechanism is an electricity-driven driving mechanism controlled by the on/off switch 52. The bottom side of thehousing 50 is a flat base adapted to support the pepper mill on a flat surface. Thetop cover shell 30 is shaped like a conical tube covered on thehousing 50 over theoutput shaft 54 and defining with the housing 50 apeppercorn chamber 38, having aninlet 385 for input of peppercorns into thepeppercorn chamber 38, twoeye lugs 33 disposed at two sides in theinlet 385, and a threadedtop neck 34. Theouter grinding member 64 is an annular grinding member formed integral with the inside wall of the threadedtop neck 34 of thetop cover shell 30. Theinner grinding member 62 is fixedly mounted on the top end of theoutput shaft 54, and suspended within theouter grinding member 64. Theinner grinding member 62 and theouter grinding member 64 form a grinding mechanism adapted to grind peppercorns into powder. Theswivel frame 40 is connected to thetop cover shell 30 and turned to close/open theinlet 385, having twopivot rods 43 disposed at two sides and respectively pivoted to theeye lugs 33 of thetop cover shell 30. - Referring to FIGS. from2 through 4 again, a
bracket 36 is disposed in thetop cover shell 30 at the bottom side of theouter grinding member 64. Thebracket 36 comprises acenter ring 364, and a plurality ofradial ribs 366 respectively radially connected between the periphery of thecenter ring 364 and the inside wall of thetop cover shell 30. Theradial ribs 366 define with the periphery of thecenter ring 364 and the inside wall of the top cover shell 30 a plurality ofopenings 362 around thecenter ring 364 for the passing of peppercorns. Theoutput shaft 54 is inserted through thecenter ring 364 and connected to theinner grinding member 62. Thescrew cap 32 is threaded onto the threadedtop neck 34 of thetop cover shell 30, forming with the threadedtop neck 34 of the top cover shell 30 a grinding chamber in which theinner grinding member 62 works with theouter grinding member 64 to grind peppercorns into powder. Theprotective cap 20 is detachably closed on thescrew cap 32 to protect the grinding chamber and thepeppercorn chamber 38 against outside dust. Theprotective cap 20 has abottom chamber 22 adapted to hold pepper powder for application. When cleaning the grinding mechanism of the pepper mill, theprotective cap 20 is removed from thescrew cap 32, and then thescrew cap 32 is unfastened from the threadedtop neck 34 of the top cover shell. After cleaning, thescrew cap 32 and theprotective cap 20 are fastened to thetop cover shell 30 again. - Referring to FIG. 5 and FIG. 2 again, after insertion of peppercorns through the
inlet 385 into thepeppercorn chamber 38 and removal of theprotective cap 20 from thescrew cap 32, the pepper mill is turned upside down with the hand H, and the on/offswitch 52 is switched on to rotate theoutput shaft 54, causing theinner grinding member 62 to grind with theouter grinding member 64 inserted peppercorns into powder, enablingground pepper powder 70 to be shaken out of thescrew cap 32 and applied to the food. When turning the pepper mill upside down, theswivel frame 40 is turned from the open position to the close position to close theinlet 385. Preferably, theswivel frame 40 is made of transparent material, so that the user can visually check the amount of peppercorns put in thepeppercorn chamber 38 and the running of the internal grinding mechanism. - A prototype of pepper mill has been constructed with the features of FIGS.1˜5. The pepper mill functions smoothly to provide all of the features discussed earlier.
- Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
