Description

Technical Field

[0001] This utility model relates to the technical field of household appliances, specifically to a coffee grinder and a coffee maker. Background Technology

[0002] Patent document CN223111483U discloses an anti-static powder-flying structure for a coffee grinder. The specific content includes an anti-static powder-flying structure for a coffee grinder, comprising a powder outlet channel and a grinding unit. The powder outlet channel is connected to the powder outlet of the grinding unit. A support is provided on the top cover of the powder outlet channel, and two parallel plasma generating needles are arranged inside the support. The plasma generating needles extend downward into the top cover. A driving device is provided on one side of the powder outlet channel. Under the action of the driving device, the support moves up and down. When the support moves downward, it causes the plasma generating needles to pass through the top cover and enter the powder outlet channel; when the support moves upward, it causes the plasma generating needles to retract into the top cover.

[0003] During operation, some flying powder will gradually cover the surface of the plasma generating needle under the action of static electricity, which will reduce the ionization effect of the plasma generating needle. This will further increase the chance of flying powder gradually covering the surface of the plasma generating needle under the action of static electricity, forming a vicious cycle and ultimately causing the plasma generating needle to fail.

[0004] Therefore, further improvements are needed. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] See Figures 1-8 This coffee grinding device includes a coffee grinding mechanism 1 with a powder outlet channel 2. The powder outlet channel 2 is equipped with two or more sets of plasma generators 3, that is, the number of plasma generators 3 set on the powder outlet channel 2 is greater than or equal to two sets.

[0027] Each set of plasma generators 3 is equipped with two adjacent plasma needles 31. The plasma needles 31 of each set of plasma generators 3 can generate positive and negative ions by ionizing the air. These positive and negative ions can neutralize the positive and negative charges formed in the powder during the grinding process, thereby eliminating static electricity in the powder.

[0028] Adjacent plasma generators 3 are located in the powder outlet channel 2 and are staggered or symmetrically arranged. By setting two or more sets of plasma generators 3, the plasma generators 3 can remove static electricity from the flying powder covering other plasma generators 3. The plasma generators 3 can complement each other to eliminate static electricity from flying powder, thereby greatly reducing the chance of the plasma generating needle 31 failing due to being covered by flying powder.

[0029] The offset positions of adjacent plasma generators 3 in the powder outlet channel 2 mean that different plasma generators 3 are spatially misaligned, for example, different plasma generators 3 form a height difference along the vertical direction.

[0030] The symmetrical arrangement of adjacent plasma generators 3 in the powder outlet channel 2 means that different plasma generators 3 (usually two plasma generators 3) are symmetrically arranged in the horizontal or vertical direction.

[0031] Furthermore, the plasma generator 3 also includes a connector 32, on which two plasma generating needles 31 are arranged side by side. The connector 32 is connected and fixed to the outside of the powder outlet channel 2. During installation, only the connector 32 and the powder outlet channel 2 need to be fixed once, which simplifies the installation process of the plasma generator 3.

[0032] In other different embodiments, the two plasma generating needles 31 can also be arranged opposite each other, that is, the centers of the two plasma generating needles 31 coincide and their ionization ends point to each other.

[0033] Furthermore, the connecting seat 32 is provided with a mounting part 321, and the outer side of the powder outlet channel 2 is provided with a mounting post 21 corresponding to the mounting part 321. The mounting part 321 and the mounting post 21 are connected and fixed by a locking member, which can be a screw. The cooperation between the mounting part 321 and the mounting post 21 can improve the stability of the connection between the connecting seat 32 and the powder outlet channel 2.

[0034] Furthermore, the outer side of the powder outlet channel 2 is provided with a pin insertion part 22 corresponding to the plasma generating needle 31. The plasma generating needle 31 extends into the inner side of the powder outlet channel 2 through the pin insertion part 22. The connecting seat 32 abuts against the pin insertion part 22. The pin insertion part 22 can limit and protect the plasma generating needle 31, improve the installation accuracy of the plasma generating needle 31, and reduce the chance of damage to the plasma generating needle 31.

[0035] Furthermore, there are two sets of plasma generators 3, which are respectively set at the powder inlet end and the powder outlet end of the powder outlet channel 2, so that the ionization effect generated by the two sets of plasma generators 3 covers the powder outlet channel 2 as much as possible, and the flying powder is not easy to adhere to the inner wall of the powder outlet channel 2 during the process of passing through the powder outlet channel 2.

[0036] The coffee grinding device also includes a drive module, which is electrically connected to two sets of plasma generators 3, simplifying the overall structure of the coffee grinding device. At the same time, since the two sets of plasma generators 3 can complement each other to eliminate static electricity from flying coffee powder, the power of each plasma generator 3 can be relatively less than that required by a single plasma generator device. The overall power of the drive module can be relatively reduced, thus reducing production costs.

[0037] Furthermore, the plasma generator 3 corresponding to the powder inlet end of the powder outlet channel 2 is arranged vertically and forms a gap with the grinding mechanism 1. Its plasma generating needle 31 extends vertically from the outside to the inside of the plasma generating needle 31, which can avoid interference between the plasma generator 3 and the grinding mechanism 1.

[0038] Furthermore, the plasma generator 3 corresponding to the powder outlet end of the powder outlet channel 2 is arranged laterally on the side of the powder outlet channel 2 facing away from the grinding mechanism 1, and its plasma generating needle 31 extends laterally from the outside to the inside of the plasma generating needle 31, which can avoid interference between the plasma generator 3 and the grinding mechanism 1.

[0039] In other embodiments, the two sets of plasma generators 3 can also be arranged opposite each other at the powder inlet or outlet of the powder outlet channel 2. Alternatively, the two sets of plasma generators 3 can be arranged side by side at the powder inlet or outlet of the powder outlet channel 2. The arrangement position and configuration (vertical or horizontal) of the two sets of plasma generators 3 can be flexibly adjusted and combined according to actual production and processing needs.

[0040] This utility model also discloses a coffee machine, including a main body 4, a funnel 5 and the above-mentioned grinding device. A powder receiving rack 41 is provided on the main body 4 at a position corresponding to the lower part of the powder dispensing channel 2 to fix the position of the funnel 5, so that the funnel 5 can receive powder more stably.

[0041] Furthermore, the main body 4 is equipped with a brewing mechanism 6, which is located adjacent to the grinding device. The water outlet of the brewing mechanism 6 is equipped with a brewing section 42 for fixing the position of the funnel 5. The coffee machine has both grinding and brewing functions, making it more convenient for users to brew coffee.

[0042] This utility model also discloses a coffee grinder, including the above-mentioned coffee grinder.

[0043] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
