Description

Technical Field

[0001] This utility model relates to the field of coffee preparation equipment, specifically an electric coffee powder loosener. Background Technology

[0002] In coffee preparation, the uniformity of coffee grounds filling and distribution directly affects extraction efficiency and the final taste of the beverage. Currently, in semi-automatic coffee machines, after the portafilter is filled, the coffee grounds are prone to clumping due to pressure and the adhesion between particles. These clumps lead to uneven water flow during extraction, resulting in localized over-extraction or under-extraction, severely impacting coffee quality.

[0003] To address these issues, traditional methods often employ manual needle-like tools for loosening the coffee grounds. This involves manually inserting a needle-like tool into the coffee grounds to stir and loosen them. However, this manual method has significant drawbacks: firstly, it is inefficient and cannot meet the rapid production demands of commercial settings; secondly, it is difficult to maintain consistent pressure and stirring angle, easily leading to uneven coffee grounds density and failing to completely resolve the problem of uneven extraction.

[0048] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0049] Please see Figures 1-8 This application provides the following technical solutions:

[0050] An electric powder loosening device includes a main body 1, a connecting part 2 at the lower part of the main body 1, and a lifting mechanism 3 and a powder loosening structure 4 inside the main body 1.

[0051] The main body 1 includes a main shell 11, a top cover 12, and a fixing frame 13. The main shell 11 has an internal cavity and a flared structure that is smaller at the top and larger at the bottom. The top cover 12 is connected to the top of the main shell 11. The fixing frame 13 is disposed inside the main shell 11. A connecting part 2 is movably disposed on the lower side of the main body 1, located below the fixing frame 13, and slidably connected to the fixing frame 13. The connecting part 2 is used to connect to an external container, such as a handle for holding coffee powder in the coffee preparation process. A lifting mechanism 3 is disposed inside the cavity of the main body 1, and the lifting frame 31 is slidably connected to the fixing frame 13. A powder loosening mechanism 4 is disposed below the lifting mechanism 3, and the powder loosening mechanism 4 includes a powder loosening drive 41 and a powder loosening component 42. The powder loosening drive 41 is connected to the lifting frame 31; the powder loosening component 42 is linked to the powder loosening drive 41, and the powder loosening component 42 can rotate under the drive of the powder loosening drive 41.

[0052] With the structure of this design, the main housing 11 is shaped for easy gripping. A container holding coffee powder, such as the coffee preparation handle 2, is connected to it. Then, the lifting mechanism 3 lowers the loosening mechanism 4, and the loosening component 42 rotates to loosen the coffee powder in the container. It should be noted that the coffee preparation handle mentioned here refers to a coffee preparation tool with a container at the front and a handle at the rear; this tool is simply called a "handle" in coffee preparation.

[0053] Based on the above implementation plan, see Figures 3-5 Considering that the depth of the container corresponding to the handle may vary, this solution includes an adjustable connecting part 2. The solution is as follows:

[0054] The connecting part 2 includes a first connecting structure 21 and a second connecting structure 22. The first connecting structure 21 is inserted into and slidably connected to the fixing frame 13, and its sliding direction is parallel to the axial direction of the main housing 11. Various connection methods can be used between the first connecting structure 21 and the fixing frame 13; this solution provides one for reference. The fixing frame 13 is generally a circular frame, and its periphery is fixedly connected to the interior of the outer housing 11. Several first connecting holes are formed on the fixing frame 13; the first connecting holes are rectangular through holes.

[0055] The first connecting structure 21 is an overall ring structure. Several first connecting components 211 are arranged on the upper part of the first connecting structure 21, and the number and position of the first connecting components 211 correspond to the first connecting holes. Each first connecting component 211 includes two symmetrically arranged insert plates, each corresponding to one of the two parallel sides of the first connecting hole. The insert plates are inserted into and slidably connected to the first connecting holes. To prevent the first connecting components 211 from separating from the fixing frame 13, a first limiting structure is provided at the upper end of the insert plates. The shape of the first limiting structure is sufficient to allow it to engage with the upper side of the first connecting hole when the first connecting component 211 moves downwards. In this design, the first limiting structure is a right-angled triangular block structure.

[0056] The second connecting structure 22 is an overall annular structure. The lower outer side of the first connecting structure 21 is provided with external threads, and the second connecting structure 22 is provided with corresponding internal threads. The two are connected by threads. When it is necessary to change the length of the connecting part 2, simply rotate the second connecting structure 22.

[0057] Furthermore, a magnet assembly is provided at the lower part of the second connecting structure 22. The magnet assembly consists of several magnets arranged in a ring array. Since the containers on the aforementioned coffee-making handles are mostly magnetically attracted, the magnet assembly at the lower part of the second connecting structure 22 allows for convenient magnetic connection with the handle.

[0058] Based on the above implementation plan, see Figure 3 and Figure 4 A lifting drive component 32, which is a motor, is fixedly mounted on the fixed frame 13, and a gear is fixedly mounted on the motor shaft. A vertical rack is correspondingly provided on the lifting frame 31. A hollow sleeve is provided in the middle of the fixed frame 13, and the lifting frame 31 is sleeved inside the sleeve. A slot for the rack to extend to the outer side is reserved on the sleeve wall. The rack of the lifting frame 31 meshes with the gear of the lifting drive component 32. Through this structure, the movement of the lifting frame 31 is driven by the rotation of the lifting drive component 32.

[0059] Based on the above implementation scheme, the powder loosening drive component 42 is fixedly installed inside the lifting frame 31. The powder loosening drive component 42 is also a motor, with its motor shaft extending downwards. A powder loosening frame 421 is fixedly installed on the motor shaft of the powder loosening drive component 42, and the powder loosening frame 421 is coaxially connected to the motor shaft of the powder loosening drive component 42. Several powder loosening needles 422 are provided on the lower side of the powder loosening frame 421.

[0060] See Figure 7 and Figure 8 The coffee loosening rack 421 in this design adopts a snowflake-shaped hexagonal structure, and the loosening needles 422 are distributed in an approximately spiral pattern, meaning that the distance from each loosening needle 422 to the axis of the loosening rack 421 is different. This structure of the loosening component 42 allows for faster and better coffee loosening.

[0061] Based on the above implementation scheme, and considering the ease of use of this device, the lifting action is activated by two downward taps. See [link / reference] Figure 4 The lifting mechanism 3 also includes a lifting trigger 33 mounted on the fixed frame 13. The lifting trigger 33 is a contact switch electrically connected to the lifting drive 32, with its contacts facing downwards. A stake is provided between the two insert plates of the first connecting assembly 211, and a corresponding insert cylinder is provided on the fixed frame 13. The stake can be inserted into the insert cylinder, and a return spring is provided on the outside of the stake.

[0062] After placing the powder loosener on the handle, release your grip and quickly tap or pull the main body 1 of the powder loosener twice to cause the part above the connecting part 2 to sink. See below. Figure 5 A trigger boss 212 is provided on the upper part of the first connecting structure 21 of the connecting part 2, and the trigger boss 212 corresponds to the contact point of the lifting trigger 33. As the upper structure descends, the trigger boss 212 touches the contact point of the lifting trigger 33 twice, thereby activating the lifting drive 32 and driving the lifting frame 31 to move the powder loosening component 4 downward. The reason for setting the lifting drive 32 to start only after two contacts is to take into account the possibility of occasional accidental activation, and setting it to start after two contacts minimizes this problem.

[0063] Based on the above implementation scheme, the powder-loosening action is automatically executed upon triggering the lifting action. This scheme includes a powder-loosening trigger 43, which also uses a contact switch. The contact of the trigger 43 is positioned facing the horizontal side of the lifting frame 31, meaning it appears on the movement path of the lifting frame 31. (See [link]). Figure 6A trigger protrusion 311 is provided on one side of the lifting frame 31. The trigger protrusion 311 is a long strip block with a notch at the top and bottom. In the initial state, that is, when the lifting frame 31 is in a high horizontal position, the contact point of the powder loosening trigger 43 is located at the lower notch of the trigger protrusion 311, and the contact point is not triggered. When the lifting frame 31 descends, the contact point is squeezed, thereby causing the powder loosening trigger 43 to cause the powder loosening drive 41 to enter the working state, driving the powder loosening component to rotate and loosen the powder.

[0064] Based on the above implementation scheme, as a further optimization of this scheme, the powder loosener is equipped with a control module. This control module sets the powder loosening drive 41 and controls its working time for each powder loosening cycle. Furthermore, after the working time is met, the corresponding lifting drive 32 of the lifting frame 31 can be reversed to return the lifting frame 31 to its original position. This powder loosener also includes a prompting component, which can be a simple sound prompt, a light prompt, or a combination of sound and light. A prompt is given after the preset powder loosening working time is reached. The control of the lifting drive 32 and the powder loosening drive 41 can be implemented using existing technology, and will not be elaborated upon here.

[0065] This solution has an internal rechargeable battery and a charging port on the outer casing 11, which facilitates the flexible use of this solution.

[0066] Based on the above implementation scheme, as a further optimization of this scheme, a switch can be installed on the upper part of the top cover 12, so that the device can be switched from standby state or power-off state to ready-to-work state by tapping.
