TECHNICAL FIELD

[0001] The application belongs to the technical field of bean grinders, and relates to a bean grinder magnetic attraction device. BACKGROUND

[0002] The bean grinder can also be referred to as a coffee grinder. The bean grinder is a kind of powder grinding tool for cutting and grinding coffee beans into coffee powder when a motor drives a mechanical cutter to rotate at a high speed. The bean grinder is provided below a powder outlet with a powder receiving cup to receive the coffee powder. Since the powder receiving cup is not fixed, the powder receiving cup often tilts or deviates from the powder outlet, resulting in that the coffee powder falls outside the powder receiving cup. CONTENT OF THE UTILITY MODEL

[0021] The technical solutions in some embodiments of the present application will be described clearly and completely below in conjunction with the drawings of some embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0022] The technical solutions of the embodiments of the present application will be described in detail below in conjunction with the drawings.

[0023] As Figs. 1 to 3As shown in the figure, the embodiment is a coffee grinder, which comprises a main machine and a powder receiving cup 2. The main machine is used to grind coffee beans into coffee powder. The main machine comprises a base 1. The main machine is also provided with a powder outlet 5. The working principle and structure of the main machine belong to the prior art in the field, and will not be described in detail herein.

[0024] The bottom of the powder receiving cup 2 is provided with a first magnetic component 3, which is a magnet. A first accommodating cavity 21 is formed in the bottom of the powder receiving cup 2. The first magnetic component is installed in the first accommodating cavity 21 by means of point gluing or strong pressing. The first accommodating cavity 21 can be fully closed or open at the lower end. In order to make the bottom of the powder receiving cup 2 beautiful, a sheet or the like can be used to cover the first accommodating cavity 21 and the first magnetic component 3. The first magnetic component 3 can also be directly injection molded in the powder receiving cup 2 during injection molding.

[0025] The base 1 is provided with a bearing plane 12 for placing the powder receiving cup 2. The bearing plane 12 is provided with a second accommodating cavity 11. A second magnetic component 4 is installed in the second accommodating cavity 11 by means of glue. The second magnetic component 4 is arranged on the base 1 and below the powder outlet 5 of the coffee grinder body. The first magnetic component 3 and the second magnetic component 4 are attracted to each other by magnetic force. In the case that the first magnetic component 3 is a magnet, the second magnetic component 4 can be selected to be a magnetic sheet or a magnet. The magnetic sheet is made of ferromagnetic material (such as soft iron, silicon steel, etc.). The magnetic sheet itself does not have magnetism, but can be temporarily magnetized under the action of an external magnetic field and thus be attracted to the magnet.

[0026] The powder receiving cup 2 is slidably placed on the bearing plane of the base 1. The size of the second magnetic component 4 is smaller than the bottom of the powder receiving cup 2. During use, the powder receiving cup 2 with the magnet is placed close to the area on the base 1 where the magnetic sheet is arranged. The magnetism exhibited by the magnetized magnetic sheet will cause the magnet in the powder receiving cup 2 to move close to the magnetic sheet on the base 1, thereby exhibiting the automatic positioning effect of the powder receiving cup 2.

[0027] The coffee grinder of the embodiment enables the powder receiving cup 2 to be adsorbed on the base 1 by the magnetic attraction between the first magnetic component 3 and the second magnetic component 4. By using the principle of magnetism, when the powder receiving cup 2 moves below the powder outlet 5, the powder receiving cup 2 can be moved to the best position on the base 1 by the magnetic attraction between the first magnetic component 3 and the second magnetic component 4.

[0028] It should be noted that in the coffee grinder, the circuit board is installed on the base 1. When the powder receiving cup 2 moves away from the magnetic sheet, the magnetism of the magnetic sheet will disappear with the removal of the external magnetic field, thereby reducing the influence of the magnetic field on the circuit board. If the influence of the magnetic field on the circuit board is not considered, the magnet can also be fixedly installed on the base 1, and the magnetic sheet can be fixedly installed on the powder receiving cup 2.

[0029] Of course, the magnet and the magnet can also be used together, but the installation of two magnets is required, which makes the assembly more complex. The use of the magnetic sheet can reduce the installation of one magnet. The installation of the magnet does not need to distinguish the N pole and the S pole, so that the assembly is simpler. Moreover, the price of the magnetic sheet is cheaper than that of the magnet, which can save the cost.

[0030] The above has described various embodiments of the present application, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles, practical applications, or improvements to the technology in the market of the embodiments, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
