Technical Field

[0001] This utility model relates to the field of coffee machine accessories technology, and in particular to a split-type coffee machine funnel. Background Technology

[0002] Coffee machines are common beverage preparation devices, and one of their core components is the coffee funnel, which holds the coffee grounds and extracts them under high pressure. To ensure the flavor of every cup of coffee, users need to regularly clean the funnel and its internal filter to remove residual coffee oils and powder.

[0003] In existing technologies, traditional coffee machine funnels typically feature a filter that is either an integral part of the funnel body or a tightly pressed-in structure. This design makes it difficult to remove the filter from the funnel body, creating blind spots for cleaning and allowing dirt and grime to accumulate over time, thus affecting coffee quality. To address this issue, separate designs where the filter and funnel body are separate have emerged. However, this separate structure inevitably creates gaps at the connection between the funnel body and the filter. During high-pressure extraction, high-pressure hot water can easily leak through these gaps, affecting not only the extraction process but also posing a safety hazard of scalding the user. Therefore, ensuring that the filter can be easily removed for thorough cleaning while maintaining a reliable seal at the connection to prevent leakage is a pressing technical problem that needs to be solved in this field.

[0004] Therefore, this utility model proposes a split-type coffee machine funnel to overcome the shortcomings of the prior art. Utility Model Content

[0007] The funnel body has an installation groove and a snap-fit ​​groove on its inner wall, and the filter screen has a second snap-fit ​​block on its outer wall that cooperates with the snap-fit ​​groove.

[0008] Furthermore, the filter screen is rotated so that the second snap-fit ​​block on it snaps into the snap-fit ​​groove on the funnel body, and at the same time, the upper edge of the filter screen is pressed against the sealing ring placed in the mounting groove to form a combination.

[0009] Preferably, the snap-fit ​​groove includes a notch formed along the axial direction of the funnel body and a groove extending circumferentially along the funnel body.

[0010] Preferably, the mounting groove is an annular groove, and the sealing ring forms a compression seal between the upper edge of the filter screen and the bottom of the mounting groove after the filter screen is installed.

[0011] Preferably, the second snap-fit ​​block, the snap-fit ​​groove, the sealing ring, and the mounting groove together constitute an installation assembly for installing the filter screen onto the funnel body.

[0012] Preferably, the outer wall of the funnel body is integrally formed with a first locking block for locking the funnel body onto the coffee machine.

[0013] Preferably, the bottom of the funnel body is provided with a liquid outlet.

[0014] Preferably, the funnel body is also connected to a handle.

[0015] Preferably, the end surface of the handle is provided with a sunburst pattern.

[0020] 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.

[0021] Example: See attached document Figure 1 - Appendix Figure 4 This utility model provides a split-type coffee machine funnel, which aims to solve the technical problems of leakage caused by poor sealing structure in existing split-type coffee machine funnels, as well as the inconvenience of disassembling and assembling the filter screen and the difficulty of cleaning.

[0022] The split-type coffee machine funnel includes a funnel body 1 and a filter screen 6 that is detachably installed inside the funnel body 1; the funnel body 1 serves as the support base for the entire device and is used to connect with the coffee machine, while the filter screen 6 is used to hold coffee powder for filtration and extraction.

[0023] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that a specific structural fit and detachable connection relationship is formed between the funnel body 1 and the filter screen 6, which is realized by the installation component 7.

[0024] The core structure will be explained in detail below: An annular mounting groove 704 is integrally formed on the inner wall of the funnel body 1, and two symmetrical snap-fit ​​grooves 702 are provided below the mounting groove 704; the mounting groove 704 is used to accommodate a sealing ring 703 made of rubber or silicone; the structure of the snap-fit ​​groove 702 includes a notch opened along the axial direction of the funnel body 1, and a groove extending circumferentially from the notch along the funnel body 1.

[0025] Meanwhile, two symmetrical second snap-fit ​​blocks 701 are correspondingly provided on the outer wall of the filter screen 6. The shape and size of the second snap-fit ​​blocks 701 are adapted to the snap-fit ​​groove 702. In the assembled state, the filter screen 6 is placed into the funnel body 1, so that the second snap-fit ​​blocks 701 of the filter screen 6 are aligned and pass through the notch of the snap-fit ​​groove 702. Then, the filter screen 6 is pressed down, and the upper edge of the filter screen 6 will contact the sealing ring 703 in the mounting groove 704 and form a pre-tightening. Then, the filter screen 6 is rotated clockwise, and the second snap-fit ​​blocks 701 will slide along the slide of the snap-fit ​​groove 702 and be locked. This bayonet connection structure ensures that the filter screen 6 can be quickly installed and removed and stably positioned inside the funnel body 1, while the sealing ring 703 is pressed after the filter screen 6 is installed, forming a reliable pressure seal, which effectively prevents the coffee liquid from leaking during the extraction process.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, to achieve quick locking of the filter screen 6, the structure of the locking groove 702 includes a notch opened along the axial direction of the funnel body 1 and a sliding groove extending circumferentially along the funnel body 1. The second locking block 701 enters the locking groove 702 through the notch during installation, and then rotates and slides in the sliding groove to complete the locking.

[0027] As another preferred embodiment, to enhance the sealing effect, the mounting groove 704 is designed as an annular groove. After the filter screen 6 is installed, the sealing ring 703 forms a compression seal between the upper edge of the filter screen 6 and the bottom of the mounting groove 704.

[0028] As a further explanation, the aforementioned second snap-fit ​​block 701, snap-fit ​​groove 702, sealing ring 703, and mounting groove 704 together constitute the mounting assembly 7 for detachably mounting the filter screen 6 to the funnel body 1.

[0029] As a preferred embodiment, in order to facilitate fixing the entire device to the coffee machine, two symmetrical first locking blocks 5 are integrally formed on the outer wall of the funnel body 1 for locking the funnel body 1 to the coffee machine.

[0030] As a preferred embodiment, in order to guide the extracted coffee liquid out, the bottom of the funnel body 1 is integrally formed with at least one liquid outlet 2.

[0031] As a preferred embodiment, to facilitate user operation, the funnel body 1 is also fixedly connected to a handle 3, and the end surface of the handle 3 is machined with a sunburst pattern 4. The sunburst pattern 4 not only increases the aesthetics, but also provides anti-slip and wear-resistant functions.

[0032] Working principle: When the filter screen 6 needs to be installed, align the second snap-fit ​​block 701 on the outer wall of the filter screen 6 with the notch of the snap-fit ​​groove 702 on the inner wall of the funnel body 1, press the filter screen 6 down so that its upper edge presses against the sealing ring 703 in the installation groove 704, and then rotate the filter screen 6 clockwise. The second snap-fit ​​block 701 will slide along the groove of the snap-fit ​​groove 702 and be locked, thus completing the installation. In subsequent use, the first snap-fit ​​block 5 on the funnel body 1 is locked onto the coffee machine by the handle 3, and the extracted coffee liquid flows out from the liquid outlet 2 at the bottom. Through the snap-fit ​​connection formed by the second snap-fit ​​block 701 and the snap-fit ​​groove 702, this utility model solves the problem of inconvenient filter screen disassembly and assembly in the prior art. At the same time, the pressed sealing ring 703 solves the problem of easy leakage of the split structure under high pressure.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
