Description

Technical Field

[0001] This utility model belongs to the technical field of coffee grinders, specifically relating to a coffee grinder powder outlet vibrating mechanism. Background Technology

[0002] In the coffee-making process, coffee beans need to be processed into coffee powder. This process is completed by a coffee grinder. The top of the coffee grinder has a container for holding coffee beans. The coffee beans enter the grinding mechanism inside the grinder and are processed into powder. The coffee powder flows out from the outlet, which is connected to the grinding mechanism and is axially positioned inside the grinder. However, due to the nature of coffee powder, it tends to adhere very easily to the wall of the outlet. Existing grinders use a manual method to push a vibrating mechanism at the outlet. The vibrating mechanism moves up and down, impacting the wall of the outlet, thus causing the coffee powder to fall out. This type of grinder requires multiple manual operations to dislodge the powder from the outlet, which is inconvenient. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figs. 1-3 The coffee grinder powder outlet vibrating mechanism shown includes:

[0024] Grinding chamber 1, the top of grinding chamber 1 is connected to bean hopper seat 2 and bean hopper 3 is connected inside bean hopper seat 2;

[0025] A rear cutter head 4 is rotatably connected to the grinding chamber 1, and a flat grinding cutter 5 is fixed to one end of the rear cutter head 4 by screws. A front cutter head 6 is provided at one end of the flat grinding cutter 5 and the front cutter head 6 is connected to the flat grinding cutter 5.

[0026] The grinding chamber base 7 is fixed to the bottom of the grinding chamber 1 by screws, and a fixing seat 8 is fixedly connected to the surface of the grinding chamber base 7. A vibration motor 10 is fixed inside the fixing seat 8 by a fixing cover 9. A powder outlet seat 11 is fixed to the bottom of the fixing seat 8 by screws, and both the fixing seat 8 and the powder outlet seat 11 are provided with a powder outlet 12 for vibrating powder discharge. The powder outlet 12 is connected to the powder discharge channel provided at the bottom of the grinding chamber 1.

[0027] One end of the grinding chamber 1 is connected to a gearbox 13 and the output shaft of the gearbox 13 is connected to the rear blade plate seat 4. The gearbox 13 is equipped with a grinding motor 14 and the output shaft of the grinding motor 14 is connected to the gearbox 13.

[0028] The top of the bean hopper 3 is magnetically attached to the bean hopper lid 15 by a magnet 25. The magnetic design makes the opening and closing of the bean hopper lid 15 more convenient. The bean hopper lid 15 can automatically be attracted or separated under the attraction of the magnet 25 without the need for force to unscrew or fasten it. It can be easily completed with one hand, improving the convenience of use for users.

[0029] The surface of the grinding chamber 1 is fitted with a liner 16, and a panel 17 is fixed to the liner 16 by screws. The liner 16 and the panel 17 provide a mounting base for other components. By installing the PCB display board 18 inside the liner 16, a reasonable layout and protection of electronic components is achieved.

[0030] The liner 16 contains a PCB display board 18, and the vibration motor 10 and the grinder motor 14 are both electrically connected to the PCB display board 18.

[0031] One end of the front blade holder 6 is connected to an insert 19 and the insert 19 is threadedly connected to the grinding chamber 1. The insert 19 is provided with a base 20, and the base 20 is connected to a scale adjustment knob 21. The scale adjustment knob 21 is marked with a scale, which can provide users with an intuitive adjustment reference.

[0032] The negative ion generator 22 is fixed to the powder outlet 12 inside the fixed base 8 by screws.

[0033] A wool ring 23 is provided at the connection between the powder outlet 12 and the powder outlet channel at the bottom of the grinding chamber 1. The wool ring 23 can prevent coffee powder from leaking out during the powder dispensing process and ensure the sealing of the connection. A sealing ring 24 is provided at the connection between the front blade seat 6 and the flat grinding blade 5. The sealing ring 24 further enhances the sealing of the grinding chamber 1 and prevents coffee beans from leaking from the screw connection during the grinding process.

[0034] The coffee grinder's powder outlet vibrating mechanism works by placing coffee beans into the bean hopper 3 and closing the bean hopper cover 15. Then, the grinder motor 14 is started by controlling the control button on the PCB display board 18. The output shaft of the grinder motor 14 is connected to the gearbox 13, and the output shaft of the gearbox 13 is connected to the rear blade holder 4, thereby driving the rear blade holder 4 to rotate. The flat grinding blade 5 fixed at one end of the rear blade holder 4 rotates accordingly to grind the coffee beans. By rotating the scale adjustment knob 21, the insert 19 can be moved axially within the grinding chamber 1, thereby causing the front blade holder 6 to move and change the gap between the front blade holder 6 and the flat grinding blade 5, thus adjusting the coarseness of the grind. After the coffee beans are ground into powder between the flat grinding blade 5 and the front blade holder 6, they enter the powder outlet 12 through the powder outlet channel at the bottom of the grinding chamber 1.

[0035] When the ground coffee powder reaches the outlet 12, the preset program in the PCB display board 18 comes into play. The user can select a specific oscillation mode on the corresponding operation area of ​​the PCB display board according to actual needs. For finely ground coffee powder, a high-frequency short-duration vibration mode can be set because fine powder adheres more strongly and needs to be shaken off quickly by high-frequency vibration. For coarsely ground coffee powder, a low-frequency long-duration vibration mode is used to avoid excessive vibration that causes coffee powder to splatter. After the oscillation mode is selected, the vibration motor 10 in the fixing base 8 starts to work. According to the instructions of the preset program, the vibration motor 10 generates vibrations of corresponding frequency, duration and amplitude. These vibrations are transmitted to the fixing base 8 and the entire powder dispensing structure, causing the coffee powder adhering to the wall of the outlet 12 to be shaken off and flow out smoothly from the outlet 12. Since coffee powder easily adheres to the wall of the outlet 12, the vibration of the vibration motor 10 can effectively solve this problem and ensure smooth powder dispensing.

[0036] As the coffee powder passes through the outlet 12, the negative ion generator 22 at the outlet 12 works continuously. The negative ions generated by the negative ion generator 22 are released into the space around the outlet 12 and come into full contact with the coffee powder. The negative ions can neutralize the static electricity generated by the coffee powder during grinding and flow, reduce the clumping of the coffee powder, make the coffee powder looser and easier to flow out. At the same time, the negative ions can also inhibit the growth of bacteria and reduce the contact between the coffee powder and oxygen, reduce the degree of oxidation, thereby protecting the aroma and flavor of the coffee powder and improving the quality of the coffee.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
