N/A
The present invention relates to the technical field of grinders, more particularly to an electronic grinder adapted for grinding and pulverizing herbs and other materials.
In daily life, people gradually begin to have personalized demands for smoking a small amount of tobacco or refined tobacco, hemp plants, hemp flowers, spices and herbs. Most of these products have to be pulverized or ground in order to effectively smoke. When grinding or pulverizing a variety of herbs, people have different requirements on the size and shape of the blades due to the difference in dryness, hardness and viscosity of different herbs. However, existing rotary shaft grinders usually have the blade fixedly connected to the shaft, therefore the blade cannot be easily replaced, thereby limiting the user to a single mode of pulverization. Additionally, portability has become a key market force in many categories, with users desiring small and more feature-packed electronic devices to serve their daily needs. Accordingly there is a need to improve upon the existing art and provide a more versatile and portable electronic grinder.

Referring to
The electronics housing 3 comprises and contains the various electronic components of the grinder including a motor 31 and related electronic components. The motor 31 drives a blade 32 by way of a drive shaft 33 extending upward from the motor 31 and disposed through the housing 3. In some embodiments, the blade 32 is removably attached to the drive shaft 33 such that the blade can be removed for cleaning or replacement. In some embodiments, the blade 32 is magnetically but removably attached to the drive shaft for easy manual replacement. This is accomplished by a lower connector 34 attached to the drive shaft 33 and an upper connector 35 attached to the blade 32. Each of the lower connector 34 and upper connector 35 include magnets 36 to provide the releasable magnetic connection. In some embodiments, the motor 31 is retained by a motor housing 37 disposed with the electronics housing 3. A clip 38 seats the motor 31 within the motor housing 37 and a bracket 39 secures the motor housing 37 to the electronics housing 3. The blade 32 may comprise various configurations two examples of which are shown in
The connector section 4 comprises an end clip 41 which connects to the bottom of the electronics housing 3. A slideable connector 42 is disposed between an upper clip 43 and a lower clip 44. In some embodiments, the connector 42 comprises a universal serial bus port (any of the various USB protocols including B, mini-B, micro-B, USB-C, or the like) and is configured to receive power from an external power supply (not shown) such as a phone with a battery or charger. In other embodiments the connector 42 comprises a Lightning connector or other multi-pin or barrel-type power connection known in the art. In some embodiments, a spring housing 45 includes a spring 46 wherein the spring housing 45 springingly engages the connector 42 such that the connector 42 is selectively deployable out of the housing 4. The spring housing 45 in combination with the spring 46 is operable to such that the connector is locked in position whether retracted or deployed such that the connector 42 does not inadvertently move. In some embodiments the spring housing 45 comprises an external button to lock/unlock the connector 42.
In some embodiments a microcontroller 47 controls the power flow at the connector 42 and in some embodiments comprises a processor (CPU), memory, and control programming for the various input and output peripherals. In some embodiments the microcontroller 47 is in electrical communication with the motor 31 in order to pass power from connector 42 thereto and to provide control commands therefor. The microcontroller is operably configured to provide over-load protection, safety protection based on temperature or speed, and can manage smart charging functionality which allows the grinder to be operated while charging.
In some embodiments, the container section 2 is removably mated to the electronics housing 3 by a magnetic connection. A sealing bushing 21 seals the top of the electronics housing and include bi-lateral magnet posts 22. A spacer 23 sits over the sealing bushing 21 and a retention clip 24 sits over the spacer 23. Magnets 25 are disposed on either side of the bottom of the container section 2. In some embodiments a grommet 26 provides a tight fitment of the container section 2 onto the housing 3. When the container section 2 is attached to the electronics housing 3, the blade 31 is seated inside the container 2 such that it can effectively grind and pulverize material placed in the container section.
The top of the container section 2 is open and terminates at cap 1, which includes a swivel-mounted cover 11. In some embodiments, the swivel-mounted cover 11 is rotatably mounted to the cap 1 by a pin 12. In some embodiments, the cover 11 is magnetically but removably latched to the cap 1 by one or more magnets 13 so that it remains closed until sufficient manual force is applied to break the magnetic connection. The cap 1 is thus openable to provide a point of entry and exit for material into and out of the container section 2. In some embodiments the cap 1 is spring loaded by one or more springs 14 to assist in the opening and closing action. An upper grommet 15 sits between the cap 1 and the top of the container section 2 to provide a tight seal and fitment. A spacer 16 is attached underneath the cap 1 between the cap 1 and the container 2.
In some embodiments the grinder is operably not only to grind and pulverize material placed in the container but also to dispense the material. In some embodiments, the blade 32 can be configured to function as a grinder when rotating in one direction and to function as a fan when rotating in another direction, or it can accomplish same depending on whether the cover 11 is open or closed. In some embodiments, the blade 32 comprises a fan-like structure to facilitate air flow as well as function as a grinding blade. Accordingly, the direction of the blade 32 can be reversed in order to force air out of the chamber and up toward to the cap 1 in order to assist in expelling and dispensing ground material from the chamber. However, in other embodiments, the blade can function both as grinder and a fan when rotating in the same direction and whether the blade functions to dispense material out of the chamber is dictated by whether the cover 11 is open.
In use, the user removes the inserts material to be ground through the open cap 1 into the container section 2. With the container section 2 secured to the electronics housing 3 and the swivel-mounted cover 11 closed, the user can activate the motor 31 by connecting connector 42 to a power source such as a computing device (smartphone, tablet, personal computer) or AC adapter. If the user desires to dispense the material in the container section, the cover 11 is opened and again the motor is activated and in a dispensing mode will generate air flow to expel the contents of the container 2 out and through the cap 1.
The materials selected for the grinder of the present invention are not particularly limiting however in some embodiments at least a portion of the container 2 is comprised of a transparent material so that the user can easily observe the contents therein.
It is appreciated and understood that the present invention provides an easy to use, compact electronic grinder that is capable of effectively pulverizing and dispensing a small amount of herb such as tobacco, hemp, Chinese herbal medicine, spices etc. for smoking or other uses. Moreover, the use of the magnetic shaft connector between the blade 31 and the drive shaft 33 provides an easy and convenient way to remove the blade for cleaning or replacement with a blade of a same or different type, depending on user preferences and the target material to be pulverized.
