Description

Technical Field

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

[0002] The filter of a pressure coffee machine's brewing head is usually fixed to the water outlet of the brewing head with screws. There is a water outlet space between the water outlet and the filter of the brewing head so that the high-pressure and high-temperature water can be evenly distributed in the water outlet space and finally sprayed out from the small holes of the filter of the brewing head to achieve coffee extraction. For example, a brewing head, coffee brewing system and coffee machine are disclosed in Chinese utility model patent with patent number CN202323132862.3. Ideally, the coffee grounds (tampd down with a tamping hammer) in the funnel should fit snugly against the brewing head filter. However, if the amount of coffee grounds is too small, gaps will form between the grounds and the filter after assembly. This results in a layer of water remaining in these gaps throughout the extraction process, leading to poor extraction and affecting coffee quality. Therefore, users often place more coffee grounds in the funnel. However, after being tamped down, the grounds become a semi-solid pouch (somewhat firm). During assembly, this interferes with the filter, causing excessive force to lock the funnel into place, making it difficult to assemble or disassemble. Conversely, if too little coffee grounds are used, the funnel may fail to fit properly. Therefore, further improvements are necessary. Utility Model Content

[0003] The present invention aims to provide an adaptive assembly structure for a coffee machine funnel to overcome the shortcomings of the prior art.

[0004] A self-adaptive assembly structure for a coffee machine funnel, designed for this purpose, includes a funnel and a coffee machine body. The coffee machine body is provided with a brewing head, and the brewing head is provided with a brewing head filter and a sealing element. During assembly, the funnel is sealed to the brewing head through the sealing element. The brewing head filter forms a gap with the brewing head and is connected to the sealing element.

[0005] The center of the brewing head filter is fixed to the brewing head by fasteners or buckles, and the remaining positions of the brewing head filter form the distance between it and the brewing head.

[0006] The bottom of the sealing element has an annular sealing portion, and the outer periphery of the brewing head filter screen is connected to the annular sealing portion.

[0007] The filter screen of the brewing head is provided with an annular flange on the outside, and the annular flange surrounds the annular sealing part.

[0008] The sealing element has a funnel-shaped sealing portion extending from its periphery. During assembly, the funnel seals together with the brewing head through the funnel-shaped sealing portion.

[0009] A powder cup is detachably attached to the funnel. The mouth of the powder cup is provided with a protrusion, which acts as a seal on the funnel sealing part when the funnel is assembled.

[0010] The brewing head is provided with a slot, and the top of the sealing element is provided with a snap-fit ​​part, which is snapped onto the slot.

[0011] The funnel has a handle on its outer side and is attached to the coffee machine body via the handle.

[0012] This invention, through structural improvements, utilizes the sealing effect of the sealing element to ensure a tight seal between the funnel and the brewing head during assembly, as well as a secure connection between the brewing head filter and the sealing element. Furthermore, due to the gap between the brewing head filter and the brewing head, the filter can move flexibly on the brewing head, maintaining a tight seal with the head throughout its movement. This effectively avoids the problems of excessive coffee powder causing interference with the filter during funnel assembly and disassembly, as seen in existing technologies. The funnel can be adaptively and securely mounted on the brewing head, enhancing its practicality. Moreover, the flexible movement of the filter ensures it remains in close contact with the coffee powder, guaranteeing high-quality coffee extraction. Simultaneously, the coffee powder container within the funnel can be adaptively adjusted, effectively avoiding the need for a high coffee powder content and facilitating user convenience.

[0015] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] See Figure 1 , Figure 2 The coffee machine funnel adaptive assembly structure includes a funnel 1 and a coffee machine body 2. The coffee machine body 2 is provided with a brewing head 3, a brewing head filter 4 and a sealing element 5. During assembly, the funnel 1 is sealed to the brewing head 3 through the sealing element 5. The brewing head filter 4 forms a gap 6 with the brewing head 3 and is connected to the sealing element 5.

[0018] This embodiment utilizes the sealing effect of the sealing element 5 to ensure that the funnel 1 can be sealed and fitted with the brewing head 3 during assembly, and that the brewing head filter 4 can be connected to the sealing element 5. Furthermore, because a gap 6 is formed between the brewing head filter 4 and the brewing head 3, the brewing head filter 4 can move elastically on the brewing head 3, and remains sealed and fitted with the brewing head 3 through the sealing element 5 during movement. This effectively avoids the problem in the prior art where excessive coffee powder interferes with the assembly and disassembly of the funnel 1 due to interference with the brewing head filter 4. Thus, the funnel 1 can be adaptively and stably assembled on the brewing head 3, making it highly practical. Moreover, because the brewing head filter 4 can move elastically on the brewing head 3, it can always maintain close contact with the coffee powder, ensuring coffee extraction quality. Simultaneously, the coffee powder containing cavity inside the funnel 1 can be adaptively adjusted, effectively avoiding the problem of requiring a high amount of coffee powder in the funnel 1, making it convenient for users.

[0019] The center of the brewing head filter 4 is fixed to the brewing head 3 by fasteners or buckles, and the remaining positions of the brewing head filter 4 form a gap 6 with the brewing head 3.

[0020] In this embodiment, a connecting hole is provided at the center of the brewing head filter 4, and a connecting mating hole is provided on the brewing head 3. The connecting mating hole and the connecting hole correspond to each other and are fixed together by fasteners, so that the center of the brewing head filter 4 can be fixed on the brewing head 3, while other positions of the brewing head filter 4 do not contact the brewing head 3 and form a gap 6. That is, the center of the brewing head filter 4 is in a fixed state, while other positions are in a flexible state. When the funnel 1 is assembled and too much coffee powder is added to it, the coffee powder acts on the brewing head filter 4. At this time, the brewing head filter 4 deforms, and the driving seal 5 follows the elastic deformation and acts as a buffer to avoid interference between the excessive coffee powder and the brewing head filter 4, so that the funnel 1 can be adaptively assembled on the brewing head 3.

[0021] The bottom of the seal 5 has an annular sealing part 7, and the outer periphery of the brewing head filter 4 is connected to the annular sealing part 7, thereby enabling the brewing head filter 4 to be effectively connected to the seal 5.

[0022] The outer side of the brewing head filter screen 4 is provided with an annular flange 8, and the annular flange 8 surrounds the outer periphery of the annular sealing part 7. The annular flange 8 can surround a part of the outer periphery of the annular sealing part 7, so as to further improve the sealing fit between the brewing head filter screen 4 and the sealing element 5.

[0023] The sealing element 5 has a funnel sealing part 9 extending from its periphery. During assembly, the funnel 1 is sealed and fitted with the brewing head 3 through the funnel sealing part 9.

[0024] A powder cup 10 is attached to the funnel 1. A protrusion 11 is provided on the mouth of the powder cup 10. The protrusion 11 acts as a seal on the funnel sealing part 9 when the funnel 1 is assembled.

[0025] In this embodiment, the powder cup 10 uses the protrusion 11 to act on the funnel sealing part 9 so that the powder cup 10 and the brewing head 3 can achieve an effective sealing fit.

[0026] The brewing head 3 is provided with a slot 12, and the top of the sealing element 5 is provided with a snap-fit ​​part 13, which is snapped onto the slot 12 through the snap-fit ​​part 13. This improves the assembly stability of the sealing element 5 and prevents it from loosening after assembly.

[0027] A handle 14 is provided on the outside of the funnel 1, and it is attached to the coffee machine body 2 by means of the handle 14.

[0028] In this embodiment, the funnel 1 is attached to the brewing head 3 by a screw fastener. When using it, the user can rotate the funnel 1 through the handle 14 to detach and attach the funnel 1, which is convenient to use.

[0029] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
