Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines. Background Art

[0002] At present, the coffee machine known in the prior art usually has a brewing unit and a grinder, and the brewing unit has a brewing chamber, and the brewing chamber can be filled with a ground product, usually ground coffee powder. The inlet side of the grinder can be filled with unground roasted coffee beans, and in order to provide hot coffee beverages, the outlet side of the grinder can provide the ground coffee powder to the opening of the brewing chamber. A grinding funnel is usually used on the outlet side of the grinder to receive the ground coffee powder, and the outlet of the grinding funnel is connected to the opening of the brewing chamber to achieve the filling of coffee powder in the brewing chamber. However, the outlet end of the grinding funnel is not tightly connected to the inlet end of the brewing chamber, and there is a gap; in the process of filling coffee powder, coffee powder is easy to leak out from the connection gap between the two, and scattered coffee powder will appear on the grinding funnel shell, the outer shell of the brewing chamber and its surrounding environment.

[0023] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0025] Embodiment 1:

[0026] A structure for preventing coffee powder from flying, comprising a flexible connecting sleeve 1, wherein the connecting sleeve 1 is hollow to form a channel. The connecting sleeve 1 can be made of silicone. One end of the connecting sleeve 1 is sleeved on the outer peripheral side of the outlet end of the grinding funnel 2, and the other end is covered at the opening of the brewing chamber 3 and forms a seamless fit with the opening edge of the brewing chamber 3 to connect the grinding funnel 2 and the brewing chamber 3. The connecting sleeve 1 is used to seamlessly connect the grinding funnel 2 and the brewing chamber 3, thereby preventing leakage of coffee powder and keeping the grinding funnel shell, the brewing chamber shell and their surroundings clean and tidy.

[0027] Specifically, a covering ring 4 is provided at one end of the connecting sleeve 1 facing the brewing chamber 3, and the covering ring 4 spreads in the circumferential direction and covers the opening circumference of the brewing chamber 3. By providing the covering ring 4, the fitting area between the connecting sleeve 1 and the opening circumference of the brewing chamber 3 can be increased, further reducing the possibility of coffee powder leakage.

[0028] Furthermore, the connecting sleeve 1 has one end of a covering ring 4 which is pressed against the opening side of the brewing chamber 3. The connecting sleeve 1 has elastic deformation capability and is pressed against the opening side of the brewing chamber 3 by elastic deformation, so that the covering ring 4 is deformed and expanded, thereby increasing the covering area and maintaining a close fit with the opening side of the brewing chamber 3. In this way, when the coffee machine vibrates during operation, the elastic deformation capability of the connecting sleeve 1 can be used to prevent the covering ring 4 from shaking up and down, thereby ensuring that the covering ring 4 is always pressed against the opening side of the brewing chamber 3, so that coffee powder will not leak.

[0029] In other embodiments, the cover ring 4 of the connection sleeve 1 can also be directly laid flat on the side of the opening of the brewing chamber 3 to achieve seamless fitting. However, in this way, the shaking generated when the coffee machine is working can easily cause the cover ring 4 to shake up and down, thereby generating a gap and causing slight leakage of coffee powder. The cover ring 4 of the connection sleeve 1 can also be directly glued to the side of the opening of the brewing chamber 3 by glue to achieve seamless fitting. Although glue can achieve a stable fitting connection, it cannot be separated and is not convenient to remove it for cleaning or replacement.

[0030] In addition, a clearance portion 5 is provided on the covering ring 4. The clearance portion 5 is an upwardly concave groove structure, which is used to fit the raised portion at the opening edge of the brewing chamber 3, ensuring that the covering ring 4 fits tightly with the opening edge of the brewing chamber 3, and can further limit the displacement of the covering ring 4 along the circumferential direction.

[0031] The connection between the connecting sleeve 1 and the outlet end of the grinding funnel 2 is maintained by friction. The connecting sleeve 1 faces one end of the grinding funnel 2, and its opening is a shrinking structure when not subject to external force, and the minimum shrinking diameter is smaller than the outlet end diameter of the grinding funnel 2. The connecting sleeve 1 utilizes its own elastic deformation, and when its opening is expanded and sleeved on the outlet end of the grinding funnel 2, it can be bound and tightly held on the outer peripheral side of the outlet end of the grinding funnel 2.

[0032] This embodiment also discloses a coffee machine, comprising the above-mentioned connecting sleeve 1. The connecting sleeve 1 is used to connect the grinding funnel 2 and the opening of the brewing chamber 3, which can effectively prevent the coffee powder from flying and keep the grinding funnel shell, the brewing chamber shell and their surroundings clean and tidy.

[0033] Embodiment 2:

[0034] Different from the first embodiment, the connection sleeve 1 is connected to the outlet end of the grinding funnel 2 by a fastener, wherein the fastener can be fastened to the connection sleeve 1 by a rope or a clamp, so as to maintain a seamless connection between the connection sleeve 1 and the outlet end of the grinding funnel 2.

[0035] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
