The cup body 2 comprises a cup wall 21 and a removable cup bottom cap 22, which is configured to be opened and closed to allow access to the crushing chamber 20. The other end of the cup body 2 is connected to the base 1. A driving device 10 is provided in the base 1, and the driving device 10 comprises a transmission shaft 101 extending to the crushing chamber. A blade group 3 is provided in the crushing chamber 20, and the blade group 3 is connected to the transmission shaft 101. In some embodiments, the blade group 3 comprises a plurality of blades 31. The base 1 comprises the base shell 11, a bracket 13 provided in the base shell 11 and configured to mount the driving device 10, and the base cover 12 provided at the lower part of the base shell 11.

The shaft connection component 41 and the blade connection component 42 are axially attracted and connected together by their respective magnetic materials 43. Therefore, the blade assembly 3 can be magnetically moved from the transmission shaft 101, so that blades of different types and configurations can be cleaned and replaced in the same way. The selected blade type can be changed according to the needs of the user and the characteristics of the target material to be ground.

[0040] refer to Fig. 9 and Fig.10 In one exemplary embodiment, the blade set 3 is a set of integrally formed cross-shaped blade sets, wherein two opposing blades are tilted upward and the other two blades are tilted downward, and each blade is triangular. In some embodiments, the edges of the blades are sharpened. However, it is worth noting that the blade set 3 can be configured in various configurations according to the desired crushing size and quality, and due to the magnetic connection disclosed in the present invention, the blade set 3 can be easily replaced on the transmission shaft 101.

[0041] like Figure 1-Figure 3 As shown, the cup bottom cap 22 includes a fixed ring 220 and a movable cap 221. The fixed ring 220 is an annular body connected to the bottom of the cup wall 21, and the movable cap 221 is a flat body covered on the fixed ring 220. A pin 222 is provided between the fixed ring 220 and the movable cap 221 to connect the two. The movable cap 221 rotates with the pin 222 as the axis to open or close the crushing chamber 20, thereby providing a channel to enter the crushing chamber 20.

[0042] like Figure 11-Figure 14 As shown, the fixing ring 220 and the movable cap 221 are respectively embedded with mutually attracting magnetic materials 224 at relative positions, so that the movable cap 221 can be fixed by the fixing ring 220. In some embodiments, the fixing ring 220 is provided with a fourth groove 2203 for embedding the magnetic material 224, and the fixing ring 220 is provided with a positioning groove 2202 for accommodating the positioning spring column 223 at a position relative to the positioning spring column 223.

The fixing ring 220 is provided with a pin hole 2201 for the pin 222 to pass through.

[0043] The movable cap 221 is provided with a third groove 2211 on the side of the pin 222, and a positioning spring column 223 is embedded in the third groove 2211. When the movable cap 221 is closed or opened, the positioning spring column 223 is embedded in the positioning groove 2202 for positioning. The movable cap 221 is provided with a mounting hole 2210 for mounting the pin 222, and a fifth groove 2212 for embedding the magnetic material 224.

[0044] Reference again Figure 1-3 , the drive device 10 includes a motor 102 and a battery 103, and the battery 103 is used to power the motor 102. In some embodiments, the motor 102 includes a high-speed low-voltage electronic motor running at 30,000 revolutions per minute and 80g-cm torque. The motor 102 can work in both counterclockwise and clockwise directions according to the application and usage preferences, and can selectively work in both directions to complete the grinding operation. In some embodiments, an external power supply (not shown) can be used to replace or supplement the battery 103. In some embodiments, the transmission device also includes a microcontroller or single-chip microcomputer 104, a power button 106, and a control button 107. Through the microcontroller 104, the control button 107 is used to switch the power button or cut off the power, and the power button 106 is used to control the forward and reverse rotation of the motor. In some embodiments, the power button 107 and / or the control button 106 can be used as a lock / unlock button, depending on the user input, such as locking / unlocking by pressing 5 seconds. In some embodiments, the microcontroller 104 includes a processor (CPU) and a memory, wherein the memory contains programming logic for controlling the grinder. The microcontroller is powered by a battery 103 or other power source and can also pass power to other components of the device. In some embodiments, the battery 103 can be charged via USB, light or other power connection. The microcontroller can operate, configure overload protection, temperature or speed safety protection, and manage intelligent charging functions to allow the grinder to be operated while charging.

[0045] In some embodiments, the base 1 is provided with an inductive switch, i.e., a trigger element 110, for detecting whether the cup body 2 is connected to the base 1. In some embodiments, the trigger element 110 is in electrical communication with the microcontroller 104. Specifically, the trigger element 110 is provided at the connection between the cup wall 21 of the cup body 2 and the base 1. If the cup wall 21 is not connected to the base 1 and the trigger element 110 is not connected, the motor 102 cannot be triggered, and the blade assembly will be prevented from rotating, which can protect the user from being injured because the grinder is not assembled properly.

[0046] like Figure 1-Figure 3As shown, in some embodiments, the cup wall 21 of the cup 2 is made of a transparent material, which allows the user to easily observe the state of the material therein. In some embodiments, the upper part of the bracket 13 has a light panel 109. The light panel 109 is provided with an indicator light to indicate the working state of the motor and illuminate the grinding chamber 20 in the cup body, so that the working state of the grinding process is clear at a glance. The light panel communicates with the single-chip computer 104. In some embodiments, the light panel 109 also has a silicone gasket 108 for isolating and sealing the gap between the base 1 and the cup body 2 to prevent the crushed material from falling into the base 1.

[0047] The present invention provides an electronic grinder that is easy to use, compact in structure, and can effectively grind small amounts of tobacco, Chinese herbs, spices, etc. for use in smoking, etc. In addition, the use of a magnetic shaft connector between the blade assembly and the drive shaft provides a simple and convenient method to remove the blade assembly for cleaning or to replace the blade assembly with the same or a different type, depending on the user's preference and the material being ground.
