Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to a detachable and switchable funnel structure. Background Art

[0002] The funnel is a support structure used to hold the filter basket in the coffee machine. After the coffee powder is put into the filter basket, hot water is forced through the filter basket by pressure to extract the concentrated coffee liquid. Common coffee machine funnels usually include a cylindrical hollow body, a filter basket, and a conical bottom for installing a coffee spout. Different ways of brewing espresso can produce coffee with different flavors. Usually, after the coffee powder is put into the filter basket, the coffee powder in the filter basket will be compacted and smoothed. The funnel with a conical bottom is difficult to place on the desktop platform, which is very inconvenient for novices and operators who need to perform this process multiple times.

[0003] Chinese patent CN203328529U discloses a filter support device for an espresso machine, comprising a support, a filter basket and a handle arranged on the support, a bottom plate arranged at the bottom of the support, and a spout arranged on the bottom plate, wherein the bottom plate is connected to the support and the spout in a separate manner; and at least one through hole is arranged on the bottom plate. The existing filter support device has a detachable bottom plate on the support, which can be used as a traditional standard support when it is detached, and a spout is arranged on the bottom plate; after the bottom plate is removed, it can be used as a bottomless support.

[0004] The bracket is provided with a connecting portion connected to the handle, a cavity is provided in the connecting portion, a spring is provided in the cavity, a stud passes through the spring and the lower end is connected to a locking piece, so that the locking piece and the bottom plate can be detachably connected. This locking piece can move on the connecting portion through the stud, and when the bottom plate is disassembled, it is necessary to press the bolt or the locking piece to achieve locking or unlocking, which is inconvenient to operate. Therefore, the existing technology needs to be improved and developed. Utility Model Content

[0005] The utility model aims to provide a detachable and switchable funnel structure with reasonable structure and convenient operation in view of the defects and shortcomings of the prior art.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The utility model discloses a detachable and switchable funnel structure, comprising a funnel body, a filter cup and a funnel bracket, wherein the filter cup is detachably loaded in the upper port of the funnel body, and a handle is installed on the outer wall of the funnel body; a coffee spout is arranged on the funnel bracket, and the funnel bracket is inserted into the lower port of the funnel body, and a magnetic attraction structure is arranged between the funnel body and the funnel bracket, and the magnetic attraction structure enables the funnel bracket to be detachably connected with the funnel body.

The positioning groove and the positioning keel constitute a circumferential position identification structure, and the funnel bracket can be installed in the lower port of the funnel body only when the positioning keel is matched with the positioning groove.

[0012] According to the above scheme, a passage opening is provided on the funnel bracket, and the coffee spout is installed on the passage opening through a fixing cap, and a through hole is provided on the fixing cap, through which the coffee spout is connected to the inner cavity of the funnel body. It can be understood that the funnel bracket as a whole is a cylindrical structure with an opening at the upper end, and the lower end of the funnel bracket has a bottom plate structure, and this bottom plate structure can be conical or disc-shaped, so as to cover the lower port of the funnel bracket. Then the passage opening is set on the bottom plate structure to connect the inner cavity of the funnel bracket. The coffee spout is loaded into the passage opening from the bottom, and the fixing cap is inserted into the passage opening from the top. The fixing cap and the coffee spout can be threadedly matched so that the two are fixed on the funnel bracket, or the fixing cap is inserted into the upper end of the coffee spout to form an interference fit so that the two are fixed on the funnel bracket.

[0013] According to the above scheme, at least two sliding fasteners are provided on the outer edge of the upper end of the funnel body. The utility model is an extraction component of a coffee machine for extracting coffee. The funnel body is connected to the coffee machine in a rotatable manner through the sliding fasteners.
