Description

Technical Field

[0001] The utility model relates to the field of coffee machines, in particular to an electric-driven centrifugal inertia coffee machine. Background Art

[0002] With the improvement of living standards, people are increasingly fond of high-quality freshly ground and brewed coffee, and are starting to make coffee by themselves.

[0003] To make a cup of freshly ground coffee, we need to bring water and coffee into contact, allow the soluble substances in the coffee powder to dissolve in the water, and then separate the water containing the coffee soluble substances from the insoluble coffee powder to get a cup of drinkable coffee liquid.

[0004] There are two mainstream ways to separate coffee grounds and coffee liquid:

[0005] 1. Pressure-free extraction:

[0006] Without adding extra pressure, use filter paper or metal filter to filter naturally. Under the action of gravity, the coffee liquid will pass through the filter paper or metal filter with tiny holes and flow into the container below, while the inedible coffee powder will remain on the filter paper, completing the coffee making.

[0007] This filtering method has three disadvantages:

[0008] 1. Only suitable for coarser coffee powder: If the coffee powder is ground too finely, it will clog the gaps in the filter paper. When the gaps in the filter paper are clogged, the filter paper loses its filtering ability and cannot filter the coffee. This extraction method requires the coffee powder to be coarser, but the coarser the particles, the smaller the specific surface area of ​​the same gram of coffee powder, resulting in less extraction of soluble substances.

[0009] 2. Long filtration time: Because the coffee liquid relies on natural gravity to penetrate downward, the gaps in the filter paper are gradually blocked during the filtration process, causing the penetration process to become slower and slower, and the extraction process takes more time.

[0010] 3. There is a lot of water remaining in the coffee powder: The wet coffee powder is like a sponge. In the absence of external pressure, a lot of water will remain in the coffee powder. This part of water cannot be effectively separated, resulting in waste.

[0011] 2. Pressurized extraction:

[0012] In order to make up for the shortcomings of pressureless extraction, pressurized extraction was born. By increasing the pressure inside the extraction container to 7-15 atmospheres, the coffee liquid can quickly penetrate the filter mesh under the drive of pressure. Under pressurized conditions, finer coffee powder can be used, and the extraction rate of soluble substances is also higher. At the same time, less liquid remains in the coffee powder, reducing waste. It is a more advanced coffee extraction method. However, in order to generate high pressure, this type of equipment has high power consumption, complex internal structure, large size, and high cost, resulting in a low household penetration rate.

[0013] There are also manual pressurized coffee machines that use the lever principle. However, in order to adapt to ergonomics, the length of the lever is limited. In order to generate a high enough pressure in the extraction container, it is very physically demanding, the consumer experience is not good, and it is difficult for the market to accept it.

[0014] Therefore, the utility model proposes an electric-driven centrifugal inertia coffee machine to solve the above problems. Utility Model Content

[0015] In order to overcome the defects in the above-mentioned prior art, the utility model provides an electrically driven centrifugal inertia coffee machine. Through the action of centrifugal force, water actively seeks pores through which it can seep out. The filtering process is faster than extraction by natural gravity. At the same time, less liquid remains in the coffee powder, reducing waste. Even finer coffee powder particles can be produced. The extraction rate is higher than that of general pressure-free extraction. Compared with pressurized extraction equipment, the production process requires less energy, has a simple structure, a small size, is portable, and is not dependent on power supply. It is more suitable for home or outdoor coffee making.

[0016] Technical Solution

[0017] An electric-driven centrifugal inertia coffee machine comprises an electric-driven mechanism at the uppermost side, wherein the lower side of the electric-driven mechanism is dynamically connected to a transmission shaft, a cover body is fixedly connected to the transmission shaft, an extraction cup body is detachably fixedly connected to the lower side of the cover body, a metal mesh for throwing out coffee liquid is arranged on the upper side of the extraction cup body, a stirring blade located inside the extraction cup body is fixedly arranged on the lower end of the transmission shaft, and a collection cup for receiving coffee is also arranged on the lower side of the extraction cup body.

[0018] Furthermore, the electric drive mechanism includes a top cover portion and a base portion, the transmission shaft passes through and is rotatably connected to the base portion, a gear plate is fixedly connected to the upper end of the transmission shaft, and a transmission plate is connected to the upper side of the gear plate.

[0019] Furthermore, a locking plate fixing shaft is fixedly connected to the lower side of the transmission disc, a one-way locking plate is connected to the locking plate fixing shaft, a locking tooth is arranged in the upper surface of the gear disc, and the one-way locking plate is unidirectionally transmitted with the locking tooth.

[0020] Furthermore, the upper end of the transmission plate is fixedly connected to the output shaft end of the motor, and the motor is fixedly connected to the top cover.

[0021] Furthermore, a battery for supplying power to the motor and a control switch for controlling the start and stop of the motor are also arranged in the top cover.

[0022] Furthermore, a connecting portion with a sealing ring is fixedly provided on the lower side of the base portion, and the connecting portion can be connected to and sealed with the upper port of the collection cup.

[0023] Beneficial Effects

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] Instead of following the natural passive separation method of pressureless extraction or the pressurized extraction method, a new approach is taken to separate the coffee powder and water by using the principle of inertia generated by the movement of matter.

[0026] The coffee powder and water are mixed inside the extraction container and the soluble substances are dissolved. Then, a force is applied to make the container rotate at high speed. Under the action of inertia, the coffee powder and water mixture in the container forms a centrifugal force. Due to the fluidity of the liquid, the coffee liquid is drilled out through the pores of the metal mesh, and the coffee powder is isolated in the container, completing the extraction.

[0027] Under the action of centrifugal force, water actively seeks out pores through which it can seep. The filtering process is faster than extraction by natural gravity. At the same time, less liquid remains in the coffee powder, reducing waste. Even finer coffee powder particles can be produced. The extraction rate is higher than general pressure-free extraction. Compared with pressurized extraction equipment, the production process requires less energy (physical strength or electricity), has a simple structure, a small size, is portable, and does not rely on power supply. It is more suitable for home or outdoor coffee making. BRIEF DESCRIPTION OF THE DRAWINGS
