Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coffee machines, in particular to an anti-static powder flying structure of a coffee bean grinder. Background Art
[0002] In current coffee machines or bean grinders, the ground coffee powder has a certain charge due to its light density and the static electricity generated when the grinding device is working. It is easy to scatter and agglomerate during the powder discharge process, resulting in problems such as poor powder discharge. By setting a plasma generator in the powder discharge channel, the positive and negative emission needles on the plasma generator ionize the air to generate positive and negative ions, neutralizing the charge carried by the coffee powder, thereby solving the problem of coffee powder scattering and agglomeration. However, during the installation and use of the plasma generator of the current bean grinder, since the emission needle is directly exposed in the powder channel and the user touches it directly, it cannot meet the safety requirements; secondly, after long-term use, the coffee powder will accumulate and adhere to the surface of the emission needle, affecting the effect of the emission needle in generating positive and negative ions, making the anti-static powder flying effect weakened or even ineffective.
[0003] CN202122762758.7 discloses a grinding mechanism and a coffee machine, the grinding mechanism comprising: a grinder; a powder channel assembly, which is detachably mounted on the grinder and communicated with the powder outlet on the grinder to form a powder outlet channel for guiding out coffee powder, the powder channel assembly having a powder blocking portion; and a plasma generator, which has two steel needles arranged in parallel for eliminating static electricity generated by the coffee powder, the plasma generator is detachably mounted on the side wall of the powder channel assembly, and the steel needles are inserted into the powder outlet channel and are located below or inside the powder blocking portion. In this technical solution, the plasma generator is detachably mounted on the side wall of the powder channel assembly, and the plasma generator is regularly disassembled to clean the coffee powder accumulated on the emission needle, which increases the inconvenience of use, and the emission needle exposed in the powder outlet channel still has a large safety hazard. Utility Model Content
[0004] The purpose of the utility model is to provide an anti-static powder flying structure for a coffee bean grinder, so as to solve the problem that a plasma generator is detachably mounted on the side wall of the powder channel assembly, and the plasma generator needs to be regularly disassembled to clean the coffee powder accumulated on the emission needle, which increases the inconvenience of use, and the emission needle exposed to the powder outlet channel still poses a great safety hazard, so as to overcome the deficiencies of the prior art.
[0005] The present utility model provides an anti-static powder flying structure for a coffee grinder through the following technical solutions, which includes a powder outlet channel and a grinding unit. The powder outlet channel is communicated with the powder outlet of the grinding unit. A bracket is provided on the top cover of the powder outlet channel. Two parallel plasma needles are arranged inside the bracket. The plasma needles extend downward into the top cover. A driving device is provided on one side of the powder outlet channel. The bracket moves up and down under the action of the driving device. When the bracket moves down, the plasma needles penetrate through the top cover and extend into the powder outlet channel. When the bracket moves up, the plasma needles are retracted into the top cover.
[0006] Further, a baffle is also provided above the bracket, and an elastic element is provided between the baffle and the bracket.
[0007] Further, the driving device is an electromagnet, and the push rod of the electromagnet is located below one end of the bracket.
[0008] The present utility model has the following beneficial effects: The emission needles are arranged on the bracket above the top cover of the powder outlet channel. The bracket drives the plasma needles to move up and down under the drive of the driving device. When the coffee grinder is working, the plasma needles penetrate through the top cover and extend into the powder outlet channel. After grinding, the plasma needles are retracted into the top cover, reducing the safety regulation hidden danger brought by the exposure of the plasma needles. At the same time, the plasma needles moving up and down in the top cover can remove the coffee powder accumulated on their surfaces. The vibration generated by the elastic element pushing the bracket to touch the top cover can conveniently clean the coffee powder accumulated on its surface, maintaining the long-term effectiveness of anti-static powder flying.

[0020] Next, refer to Figures 1 - 4 Describe an anti-static powder flying structure of a coffee grinder according to some embodiments of the present application.
[0021] An anti-static powder flying structure of a coffee grinder includes a grinding unit 2 for grinding coffee beans into coffee powder. An outlet powder channel 1 is provided at the powder outlet of the grinding unit 2 and is connected and communicated. The coffee powder ground by the grinding unit 2 enters the outlet powder channel 1 from the powder outlet and then falls into the brewing device below for brewing.
[0022] A top cover 3 is provided at the top of the flour discharging channel 1. A bracket 4 is provided on the top cover 3. Two juxtaposed plasma needles 5 are provided inside the bracket 4. The plasma needles 5 extend downward into the top cover 3. A driving device 8 is provided on one side of the flour discharging channel 1. In this embodiment, the driving device 8 is an electromagnet, and the push rod 9 of the electromagnet is located directly below one end of the bracket 4. A baffle 6 is further provided above the bracket 4, and an elastic element 7 is provided between the baffle 6 and the bracket 4.
[0023] When the coffee grinder is not grinding coffee, the push rod 9 of the non-powered electromagnet is in the released and ejected state, pushing the bracket 4 upward. The elastic element 7 is compressed, and the lifted bracket 4 drives the plasma needles 5 to retract into the top cover 3, avoiding the plasma needles 5 being exposed in the flour discharging channel 1.
[0024] When the coffee grinder starts to grind coffee, after the electromagnet is powered on, the push rod 9 retracts. The bracket 4 that loses the upward push of the push rod 9 moves downward under the reset and release action of the elastic element 7, driving the plasma needles 5 to penetrate through the top cover 3 and extend into the flour discharging channel 1, so as to prevent static electricity and powder flying of the coffee powder entering the flour discharging channel 1.
[0025] In addition to cooperating with coffee grinding and driving the plasma needles 5 to penetrate through the top cover 3 when the bracket 4 moves downward, after the coffee grinding is completed, the electromagnet can be powered on multiple times to realize the repeated up and down movement of the bracket 4 and the plasma needles 5. During the up and down movement of the bracket 4, the top cover 3 is touched multiple times, and the generated vibration can shake off the coffee powder remaining on the plasma needles 5 and in the flour discharging channel 1, realizing real-time and effective cleaning of the coffee powder and avoiding the inconvenience of use caused by regular disassembly and cleaning.
[0026] In this embodiment, a pair of convex rings are provided on the upper part of the top cover 3. A needle hole penetrating the top cover 3 is provided at the center of the convex rings. A needle seat is provided on the bracket 4, and the plasma needles 5 are arranged in the needle seat. The needle seat is matched with the convex rings. When the bracket 4 moves downward, the needle seat enters the convex rings, and the plasma needles 5 penetrate through the needle hole and the top cover 3 and extend into the flour discharging channel 1. When the bracket 4 moves upward, the needle seat moves out of the convex rings, and the plasma needles 5 retract and stay in the needle hole.
[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
