Specific Implementation

[0037] The present application will be further described in detail below with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0038] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0039] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0040] This application provides a coffee machine, such as Figure 1 As shown, the coffee machine may include a coffee machine body 1 and a portafilter assembly 2. The coffee machine body 1 has a brewing head 11. Ground coffee powder can be filled into the portafilter assembly 2, and the portafilter assembly 2 can be snapped onto the brewing head 11 to extract coffee liquid.

[0041] The coffee machine body 1 may include components such as a water tank, a heater, and a power supply. The shape of the coffee machine body 1 may be square or cylindrical. This application does not impose any special restrictions on the specific structure and shape of the coffee machine body 1. When using the coffee machine, the power supply can be used to power the heater, which can be used to heat the water in the water tank. The heated hot water can be sprayed out from the brew head 11, thereby extracting the coffee powder in the portafilter assembly 2 and forming coffee liquid.

[0042] In some embodiments, such as Figures 2 to 4 As shown, the handle assembly 2 may include a funnel 21, the outer wall of which may be provided with a connector 213, and the brewing head 11 may be provided with a connecting groove 110. The connector 213 may engage with the connecting groove 110 so that the funnel 21 is installed on the brewing head 11.

[0043] For example, the connector 213 can be arranged circumferentially along the outer wall of the funnel 21, and the connecting groove 110 can be set as a notch on the brewing head 11. When the funnel 21 is connected to the brewing head 11, the connector 213 can first be inserted into the connecting groove 110, and then the funnel 21 can be rotated to connect the funnel 21 to the brewing head 11. The connector 213 can be set as a strip-shaped or columnar protrusion, and the connecting groove 110 can be set as a strip-shaped or columnar notch adapted to the shape of the connector 213. This application does not impose any special restrictions on the specific shape of the connector 213 and the connecting groove 110.

[0044] Furthermore, multiple connectors 213 can be provided circumferentially along the outer wall of the funnel 21, and correspondingly, multiple connecting grooves 110 can be provided on the brewing head 11, thereby making the funnel 21 more securely connected to the brewing head 11 and preventing the funnel 21 from easily falling off the brewing head 11. This application does not impose any special limitation on the specific number of connectors 213 and connecting grooves 110.

[0045] To improve the versatility of the handle assembly 2, this application also provides a handle assembly 2, such as... Figures 2 to 7 As shown, the handle assembly 2 may include a funnel 21, a powder bowl 22, and a base assembly 24. The funnel 21 can be engaged with the brewing head 11. The powder bowl 22 is connected inside the funnel 21 and divides the funnel 21 into a brewing space 211 and an installation space 212. The brewing space 211 is formed between the brewing head 11, the funnel 21, and the powder bowl 22. The installation space 212 is formed on the side of the powder bowl 22 away from the brewing head 11. The base assembly 24 is detachably installed in the installation space 212.

[0046] In this way, since the portafilter 22 divides the funnel 21 into two parts, a brewing space 211 and an installation space 212, the brewing space 211 can be used to fill coffee powder, and the installation space 212 can be used to install the base assembly 24. When using the portafilter assembly 2, if the user needs to observe the coffee extraction process and effect, the base assembly 24 can be removed from the installation space 212, allowing the user to observe the coffee extraction process and effect through the installation space 212 while extracting the coffee. When the user does not need to observe the extraction process and effect, the base assembly 24 can be installed in the installation space 212 to extract the coffee. Thus, this application achieves the effect of using a bottomless funnel and also the effect of using a bottomed funnel with a single portafilter assembly 2, improving the versatility of the portafilter assembly 2.

[0047] Among them, such as Figure 7 As shown, the coffee bowl 22 can be configured as a separate component. For example, the coffee bowl 22 can be a bowl-shaped structure with a filter plate 220. The coffee bowl 22 can be fitted inside the funnel 21, and the height of the coffee bowl 22 along the aa axis is less than the height of the funnel 21 along the aa axis. When the coffee bowl 22 is inserted into the funnel 21, the internal space of the coffee bowl 22 can form a brewing space 211 for filling with coffee powder. The space in the funnel 21 at the bottom of the coffee bowl 22 can form an installation space 212 for installing the base assembly 24.

[0048] In other embodiments, the powder bowl 22 may also be integrally formed with the funnel 21. For example, the filter plate 220 may be directly connected to the funnel 21. In this way, the brewing space 211 and the installation space 212 may be formed in the spaces of the funnel 21 on both sides of the filter plate 220. This application does not impose any special restrictions on the connection method between the funnel 21 and the powder bowl 22.

[0049] In some embodiments, such as Figures 5 to 8 As shown, the handle assembly 2 may also include an elastic element 23; the elastic element 23 may be disposed between the funnel 21 and the base assembly 24, and the base assembly 24 is detachably held in the installation space 212 by the elastic element 23 and sealed between it and the funnel 21.

[0050] When the user does not need to observe the coffee extraction process and its effects, the user can insert the base assembly 24 into the mounting space 212 of the funnel 21. On one hand, the elastic element 23 can deform under the compression of the base assembly 24 and the funnel 21, increasing the friction between them and allowing the base assembly 24 to be fixed in place within the mounting space 212. On the other hand, the deformed elastic element 23 can also seal the gap between the base assembly 24 and the funnel 21 to prevent coffee leakage. Thus, the elastic element 23 serves both to fix the base assembly 24 and to seal the gap.

[0051] When the user does not need to observe the coffee extraction process and its effect, the user can simply pull out the base assembly 24. The elastic element 23 makes the assembly and disassembly of the base assembly 24 and the funnel 21 simple and convenient. The elastic element 23 can be a silicone, plastic, or rubber sealing ring; this application does not impose any special restrictions on the specific material of the elastic element 23. In other embodiments, the base assembly 24 can also be connected to the funnel 21 by screwing or snap-fitting. This application does not impose any special restrictions on the connection method between the base assembly 24 and the funnel 21.

[0052] In some embodiments, such as Figure 7 and Figure 8 As shown, the base assembly 24 may include a base 241; the base 241 may have a receiving groove 2411 arranged circumferentially along the base 241, and the elastic member 23 may be installed in the receiving groove 2411, and the base 241 is held in the installation space 212 by the elastic member 23.

[0053] For example, the base 241 can be configured as a circular bottom cover structure, and the receiving groove 2411 can be arranged on the outer side wall of the bottom cover along the circumference of the base 241, so that the elastic member 23 can be installed in the receiving groove 2411. Of course, the base 241 can also be configured as a rectangular or elliptical shape, etc. This application does not impose any special restrictions on the specific shape of the base 241.

[0054] When the base 241 is inserted into the mounting space 212, the elastic element 23 can seal between the base 241 and the funnel 21, and the base 241 can also be fixed in the mounting space 212 by the elastic element 23. In other embodiments, the receiving groove 2411 can also be provided on the inner side wall of the mounting space 212 of the funnel 21. When the base 241 is inserted into the mounting space 212, the elastic element 23 can also seal between the base 241 and the funnel 21. This application does not impose any special restrictions on the specific location of the elastic element 23.

[0055] In some embodiments, such as Figure 5 and Figure 8 As shown, the base 241 may be provided with a liquid outlet 2412; the liquid outlet 2412 may be located at the center of the base 241, and the base 241 may have a slope for guiding liquid flow to the liquid outlet 2412.

[0056] When the user does not need to observe the coffee extraction process and its effect, the user can insert the base 241 into the installation space 212 of the funnel 21. At this time, the extracted coffee liquid can flow along the slope of the base 241 to the outlet 2412. On the one hand, the base 241 can pressurize the extracted coffee liquid, allowing the handle assembly 2 to be used as a pressurized funnel. On the other hand, the base 241 can also prevent the coffee liquid from splashing. When the user removes the base 241, the handle assembly 2 can be used as a bottomless funnel. Thus, the handle assembly 2 provided in this application, through the detachable connection between the base 241 and the funnel 21, allows the handle assembly 2 to be used as both a bottomed funnel and a bottomless funnel, thereby improving the versatility of the handle assembly 2.

[0057] In some embodiments, such as Figure 7 and Figure 8 As shown, the base assembly 24 may also include a double-ended nozzle 242; the double-ended nozzle 242 may be detachably connected to the liquid outlet nozzle 2412, and the liquid flowing out from the liquid outlet nozzle 2412 may be diverted through the double-ended nozzle 242.

[0058] For example, the dispensing nozzle 2412 may have an external thread, and the double-ended nozzle 242 may have an internal thread. When the double-ended nozzle 242 is needed, it can be connected to the dispensing nozzle 2412 via the thread. In other embodiments, the dispensing nozzle 2412 and the double-ended nozzle 242 may also be detachably connected by means of plug-in or snap-fit. This application does not impose any special restrictions on the specific method of detachable connection between the dispensing nozzle 2412 and the double-ended nozzle 242.

[0059] When the user installs the double-ended spout 242 on the base 241, the extracted coffee liquid can be split through the double-ended spout 242, allowing for the simultaneous extraction of two cups of coffee. Furthermore, the double-ended spout 242 allows the user to apply force when removing the base 241, facilitating its removal. Therefore, the handle assembly 2 provided in this application, in addition to forming a bottomless funnel with the base 241, can also be used as a double-ended funnel by adding the double-ended spout 242, further improving the versatility of the handle assembly 2.

[0060] In some embodiments, the base assembly 24 may be made of plastic, silicone or metal.

[0061] For example, when the base 241 and the dual-headed nozzle 242 are separate components, the base 241 and the dual-headed nozzle 242 can be made of metal, thereby allowing the handle assembly 2 to be used as a bottomless funnel, a pressurizing funnel, or a dual-headed funnel. In other embodiments, the base 241 can also be made of plastic or silicone; this application does not impose any special restrictions on the specific material of the base assembly 24.

[0062] Furthermore, when the base 241 is made of plastic or silicone, it can also be integrally molded with the elastic element 23. Alternatively, the base 241, elastic element 23, and double-headed nozzle 242 can all be integrally molded to increase the sealing between the base assembly 24 and the funnel 21. This application does not impose any special restrictions on the specific molding method of the base assembly 24.

[0063] In some embodiments, such as Figures 2 to 6 As shown, the handle assembly 2 may also include a handle 25; the handle 25 is detachably connected to the funnel 21.

[0064] For example, the handle 25 may be provided with an external thread, and the funnel 21 may be provided with an internal thread, so that the handle 25 and the funnel 21 can be detachably connected by the thread. In other embodiments, the handle 25 and the funnel 21 may also be detachably connected by means of plug-in or snap-fit. This application does not impose any special restrictions on the specific method of detachable connection between the handle 25 and the funnel 21.

[0065] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
