Description

Technical Field

[0001] The utility model relates to the field of coffee bean grinders, in particular to a coffee bean grinder with an improved powder box structure. Background Art

[0002] A bean grinder is a device that grinds beans into powder. Taking a coffee bean grinder as an example, the ground coffee powder is used to make drip coffee, espresso, etc. The process of grinding coffee beans is to use a metal blade to cut the coffee beans step by step to make them into fine coffee powder. During the cutting process, the coffee powder will generate static electricity, causing the coffee powder to fly and be adsorbed on the powder outlet of the grinder. The flying powder will make the grinder difficult to clean. In order to alleviate the above problems, the existing technology usually adds a powder spring structure. The mainstream powder spring structure eliminates static electricity through an ion generator to prevent coffee powder from sticking to the tube wall. However, in actual use, it is found that the above structure is single and cannot achieve effective powder removal operation. Therefore, there is an urgent need for a more reasonable structure that can cooperate with the ion generator to achieve a better powder removal effect. Utility Model Content

[0026] In order to more clearly describe the present utility model, the present utility model will be further described below with reference to the accompanying drawings.

[0027] In the following description, example details are given to provide a deeper understanding of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. It should be understood that the specific embodiments are only used to explain the present utility model and are not used to limit the present utility model.

[0028] It should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of the described features, wholes, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components or their combinations.

[0029] In order to solve the above-mentioned technical problems, the present application provides a coffee grinder with an improved structure of a powder cartridge. Please refer to the attached Figure 1 to the attached Figure 6 , which includes a main body 1, a central axis tube 2 and a sleeve 3. Among them, the main body 1 is internally provided with a main control board, and the outer wall is provided with a discharge port; one end of the central axis tube 2 is connected to the main body 1 and communicates with the discharge port; the inner tube wall of the central axis tube 2 is provided with a protruding ion probe 21, and the ion probe 21 is electrically connected to the main control board. The ion probe 21 realizes control and operation through the main control board. This part is the prior art, so it will not be elaborated here; it should be understood that the central axis tube 2 and the sleeve 3 cooperate to form the aforementioned plasma powder cartridge. The outer wall of the central axis tube 2 is further provided with at least one protruding abutted shaft 22; the sleeve 3 is rotatably sleeved on the central axis tube 2, and the end far from the main body 1 is provided with a material port communicating with the discharge port. The inner wall of the sleeve 3 is provided with a step structure 31 with a fluctuating table surface, and the table surface of the step structure 31 abuts against the abutted shaft 22; by rotating the sleeve 3, the fluctuating table surface of the step structure 31 and the abutting column come into contact multiple times, and the vibration generated during the contact can cooperate with the electrostatic adsorption effect generated by the ion probe 21, so that the coffee powder adhering to the tube wall can fall off;

[0030] In a specific solution, sliding holes 23 corresponding to the number of abutting shafts 22 are further provided on the outer wall of the central shaft tube 2. An active tube 24 is also provided inside the central shaft tube 2. One end of the abutting shaft 22 is connected to the active tube 24, and the other end passes through the sliding hole 23 to protrude from the outer wall of the central shaft tube 2. The end of the active tube 24 away from the ion probe 21 is elastically connected to the inner bottom wall of the sleeve 3. The elastic connection can be achieved through structures such as springs, elastic sheets or elastic silica gels. During the specific working process, the user rotates the sleeve 3, so that the abutting shaft 22 abuts against the undulating table surface in sequence and repeatedly. At this time, due to the elastic action, the active tube 24 reciprocates with the rotation of the sleeve 3. The vibration generated by the reciprocation causes the coffee powder to fall off, and further cooperates with the ion probe 21 to eliminate static electricity, making the falling effect better. The cooperation between the sliding hole 23 and the abutting shaft 22 makes the reciprocating movement of the active tube 24 smoother and increases the intensity of the vibration.

[0031] In this embodiment, the undulating table surface is composed of a continuously connected first tooth profile surface 32 and a second tooth profile surface 33 connected at a preset interval. The first tooth profile surface 32 is an inclined surface, and the first tooth profile surface 32 is perpendicular to the inner top surface of the sleeve 3. It is not difficult to understand that by driving the abutting column to abut through the first tooth profile surface 32, the active tube 24 is driven to move in the first direction and the elastic potential energy of the foregoing elastic structure is compressed. When the abutting column rotates to the position of the second tooth profile surface 33, the abutting column quickly moves in the second direction based on the elastic potential energy and collides with the hole wall of the sliding hole 23, thereby generating vibration to make the remaining coffee powder fall off.

[0032] In this embodiment, mounting notches 34 are further provided on the undulating table surface. The number of mounting notches 34 is adapted to the number of abutting shafts 22. The mounting notches 34 are correspondingly located at the preset interval positions. The mounting notches 34 can facilitate the staff to install the abutting shafts 22 to appropriate positions.

[0033] In this embodiment, an adapter seat 25 is further included. One end of the adapter seat 25 is connected to the main body 1, and the other end is connected to the central shaft tube 2. A receiving groove 26 is further provided on the surface of the abutting part close to the main body 1 for receiving the ion probe 21. The adapter seat 25 further reduces the assembly difficulty of the ion probe 21. In a further solution, a bean grinding assembly is further included in the main body 1. Feeding ports and discharging ports communicated with the bean grinding assembly are correspondingly formed on opposite sides of the main body 1. More preferably, a base 4 and a support 5 are further included. One end of the support 5 is connected to the base 4, and the other end is connected to the main body 1. A material taking space for preventing the material taking cup is formed between the main body 1 and the base 4. The reasonable structural design enables the user to quickly take the coffee powder.

[0034] In a more preferable solution, a buffer pad is further provided on the surface of the base 4 away from the main body 1 to buffer the vibration generated during work.

[0035] The advantages of the present utility model are as follows:

[0036] 1. By rotating the sleeve, the undulating tabletop and the abutting column of the stepped structure are brought into contact multiple times. The vibration generated during contact can cooperate with the electrostatic adsorption effect generated by the ion probe, causing the coffee powder adhering to the inner wall of the pipe to fall off.

[0037] 2. The movable pipe reciprocates axially as the sleeve rotates. The vibration generated by the axial movement causes the coffee powder to fall off, further cooperating with the ion probe to eliminate static electricity, resulting in a better falling-off effect. The sliding hole and the abutting shaft cooperate to make the reciprocating movement of the movable pipe smoother and increase the vibration intensity.

[0038] The above only discloses several specific embodiments of the present utility model, but the present utility model is not limited thereto. Any changes that can be conceived by those skilled in the art shall fall within the protection scope of the present utility model.
