Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a funnel structure for a coffee machine. Background Technology

[0002] As living standards improve, coffee has gradually become a common beverage in people's lives, leading to an increasing demand for coffee machines. Espresso machines use a mixture of high-pressure steam and water to quickly pass through the coffee layer, instantly extracting the coffee. This results in coffee with a high temperature, low caffeine and other impurities, and a rich flavor.

[0003] Espresso machines are generally equipped with a funnel structure with a handle. To make coffee, the funnel structure first collects the coffee grounds, then a grinder evens the grounds within the funnel. Next, a coffee maker uses a puncture needle to break up any clumps, and finally, a tamper is used to tamp the grounds to ensure even extraction and full extraction. For details, please refer to Chinese patent application CN202322432519.4, entitled "A Coffee Needle-Type Coffee Maker".

[0004] However, the above coffee preparation process requires the use of a "coffee three-piece set" (i.e., a coffee spreader, a coffee needle, and a tamper), which is costly and complicated to operate. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a low-cost and easy-to-operate funnel structure for coffee machines, based on the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a funnel structure for a coffee machine, including a funnel for containing coffee powder and a handle installed on the side of the funnel, characterized in that: a vibration device for vibrating the coffee powder in the funnel is installed on the handle so that the coffee powder is evenly distributed under the vibration.

[0007] In order to vibrate the coffee powder in the funnel, the handle has a housing cavity inside, and the vibration device includes a vibrating element with a power output end, which is housed in the housing cavity, and the power output end abuts against the inner wall of the housing cavity.

[0008] To ensure contact between the power output end and the inner wall of the accommodating cavity, the vibration device also includes...

[0009] A limiting element is provided on the handle; and

[0010] An elastic element acts between the vibrating element and the limiting element to ensure that the power output end always tends to abut against the inner wall of the accommodating cavity.

[0011] To facilitate the installation of the elastic element, the elastic element is a compression spring, which is housed in the accommodating cavity, and the two ends of the compression spring respectively abut against the opposite surfaces of the vibration element and the limiting element.

[0012] To facilitate the positioning of the elastic element, the limiting member has an installation groove at one end facing the elastic element for the elastic element to be inserted.

[0013] To facilitate adjustment of vibration amplitude, the limiting member is threadedly connected to the handle and has an operating part extending out of the handle. The rotation axis of the limiting member extends along the compression direction of the elastic element, so that the limiting member can adjust the compression amount of the elastic element during rotation.

[0014] To facilitate the mold making and processing of the handle, as well as the installation of the vibration device, the handle includes:

[0015] The handle body is mounted on the rear side of the funnel, has the aforementioned receiving cavity inside, and has an opening at the rear end; and

[0016] A handle end cap is installed at the rear opening of the handle body;

[0017] The power output end is located at the front end of the vibration element, and the limiting member is threadedly connected to the handle end cap.

[0018] Preferably, the vibration element is a vibration motor assembly.

[0019] In order to supply power to the vibrating element, a power supply device for supplying power to the vibrating element is also included.

[0020] To facilitate adjustment of the vibration frequency, the power supply device includes:

[0021] The battery pack includes at least two batteries housed within the accommodating cavity and electrically connected to the vibrating element; and

[0022] A control switch, located on the handle, is used to control the battery pack to operate in series or in parallel.

[0023] Compared with the prior art, the advantages of this utility model are as follows: by installing a vibration device on the handle for vibrating the coffee powder in the funnel, the coffee powder that was originally piled up in a "small mountain" shape can be quickly and evenly distributed in a horizontal state under the vibration action of the vibration device, and the clumped coffee powder can be shaken apart, which is more conducive to the uniform extraction of coffee. The vibration device here efficiently replaces the powder mixer and powder needle, which is low in cost and simple to operate. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0028] like Figures 1 to 2 The image shows a preferred embodiment of the funnel structure for a coffee machine according to the present invention. This funnel structure for a coffee machine includes a funnel 1, a handle 2, a vibration device 3, and a power supply device 4.

[0029] Funnel 1 is used to hold coffee powder.

[0030] The handle 2 includes a handle body 21 and a handle end cap 22. Specifically, the handle body 21 is installed on the rear side of the funnel 1, has an internal receiving cavity 211 and an opening at the rear end; the handle end cap 22 is installed at the rear opening of the handle body 21.

[0031] The vibration device 3 is used to vibrate the coffee powder in the funnel 1 to ensure that the coffee powder is evenly distributed under the vibration. In this embodiment, the vibration device 3 includes a vibration element 31, a limiting member 32, and an elastic member 33.

[0032] Specifically, the vibration element 31 is a vibration motor assembly, which is housed in the accommodating cavity 211 and has a power output end 311 at its front end;

[0033] The limiting member 32 is threadedly connected to the handle end cap 22. Its front end has a mounting groove 321 and its rear end has an operating part 322 that extends out of the handle 2. The rotation axis of the limiting member 32 extends in the front-back direction.

[0034] The elastic element 33 is a compression spring, which is housed in the accommodating cavity 211 and can extend and retract in the front-back direction. The rear part of the compression spring is inserted into the mounting groove 321, and the two ends of the compression spring abut against the opposite surfaces of the vibrating element 31 and the limiting element 32, so that the power output end 311 of the vibrating element 31 always tends to abut against the inner wall of the accommodating cavity 211.

[0035] In addition, since the rotation axis of the limiting member 32 extends along the compression direction of the elastic member 33, the limiting member 32 can adjust the compression amount of the elastic member 33 during rotation, thereby changing the impact force applied by the vibrating element 31 to the funnel 1, and then changing the vibration amplitude of the coffee powder in the funnel 1 to adapt to coffee powder with different roasting degrees.

[0036] The power supply device 4 is used to supply power to the vibration element 31. In this embodiment, the power supply device 4 includes a battery pack 41 and a control switch 42. Specifically, the battery pack 41 includes two batteries 411 housed in the accommodating cavity 211 and electrically connected to the vibration element 31; the control switch 42 is mounted on the handle end cover 22 and is used to control the battery pack 41 to work in series or in parallel, thereby changing the vibration frequency of the vibration element 31.

[0037] In this embodiment, when the limiting member 32 is screwed in to its deepest point, the elastic member 33 is compressed to its maximum, and the impact force of the vibrating element 31 is at its maximum. When the limiting member 32 is screwed in to its shallowest point, the elastic member 33 is compressed to its minimum, and the impact force of the vibrating element 31 is at its minimum. When the battery pack 41 operates in series, the vibration frequency of the vibrating element 31 doubles, and the number of times the vibrating device 3 impacts the funnel 1 is approximately 300 times / minute. When the battery pack 41 operates in parallel, the vibration frequency of the vibrating element 31 is halved, and the number of times the vibrating device 3 impacts the funnel 1 is approximately 150 times / minute. After multiple tests, it was found that for coffee powder with a lot of oil, fine texture, and a small amount of clumps, a low-frequency, high-impact method is most effective, while for coffee powder with less oil and coarser texture, a high-frequency, low-impact method is most effective.

[0038] The working principle of this embodiment is as follows:

[0039] (1) Before receiving powder, rotate the limiting part 32 to compress the elastic part 33 to a suitable length to adjust the vibration amplitude according to the requirements;

[0040] (2) After receiving the coffee powder, turn on the control switch 42 to start the vibration element 31 and change the vibration frequency of the vibration element 31 by controlling the battery pack 41 to work in series or in parallel. The vibration element 31 starts to vibrate at high frequency and transmits the coffee powder in the funnel 1 through the handle 2. The coffee powder that was originally piled up in the shape of a "small mountain" is quickly and evenly distributed into a horizontal state under the action of vibration, and the clumped coffee powder can be shaken apart, which is more conducive to the uniform extraction of coffee. It can be seen that the vibration device 3 of this solution efficiently replaces the powder homogenizer and the powder distribution needle.
