Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a coffee grinder that facilitates cleaning of the grinding chamber. Background Technology

[0002] A coffee grinder is a device that grinds coffee beans into coffee powder. The ground coffee powder is used to make drip coffee, espresso, and other coffees. The grinding process involves using metal blades to cut the coffee beans into fine powder. During the cutting process, the coffee powder generates static electricity, causing coffee powder to fly up and adhere to the grinder's outlet, making the grinder difficult to clean.

[0003] Existing products typically use silicone / rubber / metal baffles in the grinding chamber to cause coffee grounds to clump together and fall off prematurely. Additionally, the coffee grinder's outlet is usually metal, and grounding it can reduce static electricity to some extent. However, this method has the following drawbacks: the silicone / rubber / metal baffles will cause the coffee grounds to clump together, resulting in clumping, which severely affects the flavor of the coffee; the silicone / rubber / metal baffles will fatigue and deform after prolonged use, leading to decreased effectiveness and requiring periodic replacement; grounding only partially reduces static electricity and cannot completely eliminate it from the coffee grounds. Utility Model Content

[0004] The purpose of this invention is to solve the problems of coffee grinders in the background art mentioned above, and to provide a coffee grinder that is easy to clean the grinding chamber.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a coffee grinder that facilitates cleaning of the grinding chamber, comprising a grinder body, a grinding chamber installed inside the grinder body, a powder outlet on the side wall of the grinding chamber, a powder outlet tube connected to the powder outlet, an electrostatic detector installed on the inner wall of the grinder body, the electrostatic detector further comprising an electrostatic detection plate installed on the outer wall of the grinding chamber, and an ion generator installed on the inner wall of the grinder body, the ion generator further comprising an emitting component for emitting negative ions installed between the grinding chamber and the powder outlet tube.

[0006] Furthermore, the emitting component consists of electrode plates respectively mounted on both sides of the powder outlet.

[0007] Furthermore, the emitting component is an electrode tube fitted onto one end of the powder outlet tube and connected to the grinding chamber.

[0008] Furthermore, both the grinding chamber and the powder outlet pipe are made of stainless steel.

[0009] Furthermore, the powder outlet pipe is installed at an angle on the outer wall of the grinding chamber.

[0010] Furthermore, an antistatic coating is applied to the inner wall of the powder outlet pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By installing an electrostatic detector and ion generator inside the coffee grinder, the static electricity level inside the grinding chamber can be monitored in real time, and negative ions can be emitted to neutralize the static electricity. This effectively reduces the electrostatic adsorption of coffee grounds on the inner walls of the grinding chamber and the powder outlet tube, thereby preventing coffee grounds from clogging and leaving residue, and improving the cleanliness and efficiency of the equipment.

[0013] 2. Due to the synergistic effect of the electrostatic detector and ion generator, coffee grounds adhere to the grinding chamber and outlet pipe, making cleaning the grinding chamber easier and faster for users. Frequent disassembly and cleaning of the equipment is eliminated, saving time and effort and extending the equipment's lifespan.

[0014] 3. The grinding chamber and dispensing tube are made of stainless steel, which not only has excellent corrosion resistance and durability, but also features an anti-static coating on the inner wall, further reducing coffee grounds adhesion. These designs not only improve the cleaning efficiency of the equipment, but also extend its service life and reduce maintenance and replacement costs. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Combination Figures 1 to 5 The coffee grinder shown is easy to clean. It includes a grinder body 1, a grinder hopper 2 installed inside the grinder body 1, a powder outlet 3 on the side wall of the grinder hopper 2, a powder outlet tube 4 connected to the powder outlet 3, an electrostatic detector 5 installed on the inner wall of the grinder body 1, the electrostatic detector 5 also includes an electrostatic detection plate 51 installed on the outer wall of the grinder hopper 2, and an ion generator 6 installed on the inner wall of the grinder body 1. The ion generator 6 also includes an emitting component 61 for emitting negative ions installed between the grinder hopper 2 and the powder outlet tube 4.

[0024] Example 1

[0025] like Figure 4 As shown, the emitting component 61 consists of electrode plates 61a installed on both sides of the powder outlet 3. After the grinder is started, the motor below the grinding chamber 2 drives the blades inside the grinding chamber 2 to grind the coffee beans. At this time, the electrostatic detector 5 monitors the electrostatic situation inside the grinding chamber 2 in real time. The electrostatic detector plate 51 is installed on the outer wall of the grinding chamber 2 and can sense the electrostatic changes inside the grinding chamber 2. When the electrostatic detector 5 detects the accumulation of electrostatics, the ion generator 6 is started. Through the emitting component 61, the two electrode plates 61a emit negative ions. The negative ions neutralize the positive charge on the surface of the coffee powder inside the grinding chamber 2, reducing the electrostatic adsorption phenomenon and preventing the coffee powder from adsorbing on the inner wall of the grinding chamber 2 and the powder outlet tube 4 due to electrostatics.

[0026] Example 2

[0027] like Figure 5As shown, the emitting component 61 is an electrode tube 61b that is fitted onto one end of the powder outlet tube 4 and connected to the grinding chamber 2. The electrode tube 61b has the same function as the electrode plate 61a. Unlike the emitting component 61 in Embodiment 1, the electrode tube 61b can be threaded onto the outer wall of the powder outlet tube 4 for easy installation and disassembly.

[0028] The emitting component 61 is connected to the ion generator 6 via wires, and the coffee grinder uses a microcontroller unit, such as an MCU controller, to process various electrical signals and control the working state of the grinder motor, thereby controlling the operation of the coffee grinder.

[0029] Both the grinding chamber and the powder outlet tube 4 are made of stainless steel, which has good corrosion resistance and durability, and is easy to clean. The powder outlet tube 4 is installed at an angle on the outer wall of the grinding chamber 2, which makes it easier for coffee powder to slide off, reducing accumulation and flying powder. The angle of inclination is usually designed between 30 and 45 degrees. The inner wall of the powder outlet tube 4 is coated with an anti-static coating to further reduce the static electricity adsorption of coffee powder on the inner wall of the outlet tube, ensuring that the coffee powder flows out smoothly.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
