Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, specifically to a portable coffee grinder. Background Technology

[0002] With the improvement of living standards and people's tastes, more and more people have come to enjoy drinking coffee and other beverages. Coffee grinders are the most labor-saving and efficient tools for grinding coffee beans and other products. During the crushing and grinding process, static electricity is generated due to friction between the coffee beans and the grinding blades, causing the coffee powder to carry a certain charge and resulting in flying coffee powder. To solve this problem, coffee grinders were invented to address the issue of static electricity in coffee powder. This is mainly achieved by incorporating a plasma generator in the coffee channel. The positive and negative electrodes of the plasma generator ionize air molecules to generate positive and negative ions, neutralizing the charge carried by the coffee powder and thus solving the flying coffee powder problem. However, current coffee grinders of this type still have the following problems: firstly, they directly use 220V AC mains power, which is unsafe and inconvenient for use in places without AC mains power; secondly, the plasma generator is usually exposed on the outside of the machine body, resulting in poor aesthetics; and thirdly, the powder dispensing structure is not designed properly, and flying coffee powder still occurs. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a portable coffee grinder with a more reasonable structural design, portability for use in situations without mains power, a more aesthetically pleasing appearance, and ideal control over coffee powder spillage.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A portable coffee grinder includes a main unit, a motor, a housing, and a powder dispensing structure. The main unit and motor are installed in the housing, and the motor drives the main unit to operate. The powder dispensing structure is connected to the powder dispensing channel of the main unit. A plasma generator is arranged near the powder dispensing channel. The machine also includes a rechargeable battery with low-voltage output, which provides low-voltage power to the motor. The powder dispensing structure includes a powder dispensing pipe and a powder dispensing cover. The powder dispensing pipe is connected to the powder dispensing channel, and the powder dispensing cover is fitted over the outside of the powder dispensing pipe and assembled and fixed to the housing. The powder dispensing cover blocks part of the outlet of the powder dispensing pipe. The plasma generator is installed inside the housing, and the electrodes of the plasma generator extend into the powder dispensing channel.

[0005] Furthermore, an upward-protruding mounting cover is provided at the inlet end of the powder outlet pipe, and the mounting cover is opposite to the powder outlet channel; the upper end of the mounting cover is an open structure, and a plasma support is installed at the open structure. The plasma generator is installed on the plasma support, and the plasma support is covered by the powder outlet cover.

[0006] Preferably, the plasma support has an "n" shaped structure, which spans across the mounting cover, and the electrodes of the plasma generator extend from above through the plasma support into the powder outlet channel inside the mounting cover.

[0007] Furthermore, the powder outlet pipe is inclined downwards, and a downward-extending blocking part is provided at the front end of the powder outlet cover, which blocks the outlet of the powder outlet pipe below and in front of it.

[0008] Furthermore, a base is provided at the bottom of the housing, the rechargeable battery is placed in the base, and the switch and display mechanism are located on the housing.

[0009] Preferably, the output voltage of the rechargeable battery does not exceed 36V, such as a 24V power supply; the power connector of the rechargeable battery is located on the casing and is connected to the circuit board of the main unit.

[0010] This invention, by incorporating a rechargeable battery and using low-voltage (e.g., 24V) power, not only allows the grinder to be easily carried to locations without mains power, but also enhances safety. Furthermore, by placing the plasma generator inside the machine body, it is not visible from the outside, resulting in a more aesthetically pleasing design. Additionally, the use of a powder outlet pipe in conjunction with the powder outlet cover and plasma generator to form the powder outlet structure more effectively prevents secondary powder spillage.

Detailed Implementation

[0016] In this embodiment, refer to Figures 1-4The portable coffee grinder includes a main unit 1, a motor 3, a housing 2, and a powder dispensing structure. The main unit 1 and motor 3 are installed in the housing 2. The motor 2 drives the main unit 1 to grind coffee beans. The powder dispensing structure is connected to the powder dispensing channel 10 of the main unit 1. A plasma generator 7 is located near the powder dispensing channel 10. The grinder also includes a low-voltage rechargeable battery 5, which provides low-voltage power to the motor 3. The powder dispensing structure includes a powder dispensing pipe 6 and a powder dispensing cover 8. The powder dispensing pipe 6 is connected to the powder dispensing channel 10. The powder dispensing cover 8 is fitted over the powder dispensing pipe 6 and fixed to the housing 2. The powder dispensing cover 8 blocks part of the outlet of the powder dispensing pipe 6 to prevent some coffee powder from being sprayed into the powder receiving cup and causing secondary powder scattering. The plasma generator 7 is installed inside the housing 2 and is not visible from the outside. The electrodes of the plasma generator 7 extend into the powder dispensing channel 10.

[0017] An upward-protruding mounting cover 61 is provided at the inlet end of the powder outlet pipe 6, and the mounting cover 61 is opposite to the powder outlet channel 10; the upper end of the mounting cover 61 is an open structure, and a plasma support 71 is installed at the open structure. The plasma generator 7 is installed on the plasma support 71, and the plasma support 71 is covered by the powder outlet cover 8 and cannot be seen from the outside.

[0018] The plasma support 71 has an "n"-shaped structure and spans across the mounting cover 61. The electrodes of the plasma generator 7 extend from above through the plasma support 71 into the powder outlet channel 10 inside the mounting cover 61 (the powder outlet channel 10 extends from the main unit 1 into the mounting cover). This design of the plasma support 71 to block coffee powder prevents coffee powder from flying onto the electrodes of the plasma generator 7, thus preventing them from sticking to the coffee powder and causing malfunction.

[0019] The powder outlet pipe 6 is inclined downwards, and a downward-extending shield is provided at the front end of the powder outlet cover 8, which blocks the outlet of the powder outlet pipe 6 below and in front of it. This can block residual flying powder without affecting powder dispensing, thus helping to solve the problem of secondary flying powder.

[0020] A base 4 is provided at the bottom of the housing 2, a rechargeable battery 5 is placed in the base 4, and a switch and display mechanism are provided on the housing 2.

[0021] The output voltage of the rechargeable battery 5 does not exceed 36V, such as a 24V DC power supply, and the motor 3 can be a DC motor. The power interface of the rechargeable battery 5 is located on the housing 2 and is connected to the circuit board of the main unit 1. The power interface can be a TYPE-C interface. This allows for simultaneous charging and use, and the charging will automatically stop when the battery is fully charged. The charging process uses a TYPE-C 5V voltage booster to 24V, and then supplies power to the rechargeable battery 5 through the circuit board.

[0022] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
