These and other features and advantages of the invention will become more readily appreciated when considered in connection with the following description of the presently preferred embodiments, appended claims and accompanying drawings, in which:
Referring to the Figures, wherein like numerals indicate corresponding parts throughout the several views, one aspect of the present disclosure is related to a portable blender 20 that can be powered by a handheld drill or impact driver 22 (or any suitable handheld motorized tool with a rotational output). The blender 20 can be used to mix components on a job site (for example, drywall putty) or can be used to blend food or perform any suitable blending or mixing operation.
The blender 20 includes a blender jar or container 24 that is generally cylindrical in shape and has an open first end and a closed second end. An outer surface of the container 24 is threaded adjacent the open first end to engage with a threaded cap 26. The cap 26 can be removably secured with the open first end of the container 24 in order to trap contents within the blender 20 during blending. The cap 26 has a first side that faces towards an interior of the container 24 when the cap 26 is engaged with the container 24 to enclose an interior of the container 24 and a second side that faces away from the interior of the container 24. In some embodiments, the cap 26 and/or the container 24 maybe provided with one or more seals to seal contents being blended within the interior of the container 24. In some embodiments, the container 24 and cap 26 maybe releasably engaged with one another through other means than the threaded connection of the exemplary embodiment. The container 24 and the cap 26 maybe made of plastic or any suitable material.
A rotating blade piece 28 is fixedly attached with and extends fully through and past opposite sides of the cap 26. In the exemplary embodiment, the rotating blade piece 28 is centrally located on the cap 26.
In the exemplary embodiment, the rotating blade piece 28 is made of metal (for example, stainless steel) and has a shaft or shank portion 30 that extends through a circular opening in the cap 26. The rotating blade piece 28 also includes a plurality of blades with sharp edges that are disposed on the first side of the cap 26 and that extend outwardly from the shank portion 30. In the example embodiment, the blades have a cross-blade configuration with four total blades being evenly spaced from one another around the shaft. In some embodiments, the blades could have other configurations, e.g., there could be more or fewer than four blades and the blades could have different features such as serrations depending on the types of objects to be blended.
Where it extends through the cap 26 from the first side of the cap 26 to the second side of the cap 26, the rotating blade piece 28 is sealed to the cap 26 to prevent the contents of the container 24 from leaking out of the container 24. In some embodiments, at least one elastomeric seal engages both a cylindrical portion of the shank 30 and the cap 26 to seal the rotating blade piece 28 against the cap 26. The rotating blade piece 28 may also be supported by one or more bearings to facilitate free rotation of the rotating blade piece 28 relative to the cap 26.
On an opposite side of the rotating blade 28 from the blades, the shank portion 30 is shaped to be received into the chuck of a handheld tool, such as a drill or an impact driver 22. As illustrated in
The drill or impact driver 22 engages with the shank portion 30 on an opposite side of the cap 26. In some embodiments, the rotating blade 28 can be removable from the cap 26 and replaced when worn out or replaced with a differently configured rotating blade that is optimized for blending a different type of object.
In operation, the user fills the container 24 with an object to be blended, e.g., building materials to be mixed, or food (such as ice, fruits, soups, vegetables, etc.). The user then joins the cap 26 with the container 24. In the exemplary embodiment, the user threads the cap 26 onto the container 24 to trap the objects inside the interior of the container 24. Next, the user flips the container 24 upside down (so that the cap 26 is below the container 24) and inserts the shank portion 30 of the rotating blade 28 into to the chuck of the handheld tool 22 and tightens the chuck about the shank portion 30. The user can then turn on, or activate, the motorized handheld tool 22 to rotate the rotating blade piece 28 relative to the cap and blend the object in the container 24. If the handheld tool 22 has multiple speeds, then the user can adjust the blending rate by adjusting the speed on the handheld tool 22.
Obviously, many modifications and variations of the present invention are possible in light of the above teachings and may be practiced otherwise than as specifically described while within the scope of the appended claims. Additionally, it is to be understood that all features of all claims and all embodiments can be combined with each other as long as they do not contradict each other.
