Description

Technical Field

[0001] The utility model relates to the technical field of beverage machine parts, in particular to a manual powder tamper. Background Art

[0002] When using a semi-automatic pressure coffee machine, you need to use a brewing funnel to collect the coffee powder ground by the grinder, and then put it into the brewing head of the coffee machine. The brewing head releases hot water to flow through the brewing funnel to extract the coffee powder and brew coffee liquid. In order to ensure that the coffee powder is fully extracted, before installing the brewing funnel to the brewing head, you need to use a powder tamper to compact the coffee powder in the brewing funnel and expel the air in it.

[0003] The current powder tampers include automatic powder tampers and manual powder tampers. The manual powder tampers are widely used because they are simple to operate and easy to clean. The main part of the manual powder tampers is the powder hammer, which uses the weight of the powder hammer combined with the pressure of the user to quickly and easily complete the powder compaction. However, since the weight of the powder hammer is concentrated on the hammer head, it is easy to cause uneven compaction or splashing of coffee powder due to the imbalance of the hammer head, which affects the compaction effect. Utility Model Content

[0004] The utility model aims to provide a manual powder tamper to solve the problem that when using a powder tamping hammer to tamp powder, the weight is concentrated on the hammer head, and the unbalanced hammer head is likely to cause uneven powder tamping or coffee powder splashing, thus affecting the powder tamping effect, so as to overcome the shortcomings of the prior art.

[0006] Furthermore, the connection portion of the handle is hinged to the upper portion of the pressing plate, and the handle is flipped up and down with the connection point with the pressing plate as the center, so that the handle can be unfolded and folded.

[0007] Furthermore, a hinge shaft is provided at the end of the connecting portion of the handle, and a hinge shaft seat matching with the hinge shaft is provided at the upper portion of the pressing plate.

[0008] Furthermore, the connecting portion and the holding portion are vertically connected, and when the handle is unfolded, the outer surface of the connecting portion abuts against the upper part of the pressure plate, and when the handle is folded, the inner surface of the connecting portion abuts against the upper part of the pressure plate, and the holding portion abuts against the outer wall of the shell.

[0009] Furthermore, the gripping portion is arc-shaped, and its curvature is consistent with the curvature of the shell.

[0010] Furthermore, there are two handles and they are symmetrically arranged with the center of the pressure plate as the axis.

[0011] Furthermore, the opening is provided with a connecting ring extending downward and an annular flange extending horizontally, and the connecting groove is a clamping groove arranged at the lower edge of the annular flange.

[0012] Furthermore, the annular flange is provided with a receiving groove, and the receiving groove is used to receive the gripping part.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] Refer to the following Figure 1-Figure 7 A manual powder tamper according to some embodiments of the present application is described.

[0031] A manual tamper includes a housing 1, a pressing plate 2 and a handle 3. The housing 1 is a hollow cylindrical structure with an opening 4 at the bottom. A horizontally extending annular flange 12 is provided around the opening 4. A plurality of connecting grooves 5 are provided at the lower edge of the annular flange 12. A convex tooth for connecting a brewing head of a coffee machine is provided at the mouth of a brewing funnel 8. The connecting groove 5 can be screwed into the convex tooth to install and connect the housing 1 to the brewing funnel 8. In this embodiment, the connecting groove 5 is a card slot.

[0032] A pressing plate 2 is provided in the housing 1, and the handle 3 includes a connecting portion 6 and a gripping portion 7. The connecting portion 6 of the handle 3 extends from the top of the housing 1 into the housing 1 and is connected to the pressing plate 2. When powder pressing is required, the gripping portion 7 is pressed down to drive the pressing plate 2 to slide downward in the housing 1 to press the coffee powder in the brewing funnel 8. After the powder pressing is completed, the gripping portion 7 is pulled up to drive the pressing plate 2 to be retracted upward in the housing 1.

[0033] Among them, a hinge shaft 9 is provided at the end of the connecting part 6 of the handle 3, and a hinge shaft seat 10 is provided on the upper part of the pressing plate 2. The hinge shaft 9 and the hinge shaft seat 10 cooperate to realize the hinge connection between the connecting part 6 of the handle 3 and the upper part of the pressing plate 2. The handle 3 is flipped up and down with the connection point with the pressing plate 2 as the center to realize the unfolding and folding of the handle 3.

[0034] The connecting portion 6 and the holding portion 7 of the handle 2 are vertically connected, so when the handle 3 is unfolded, the outer surface of the connecting portion 6 abuts against the upper part of the pressing plate 2, increasing the contact area between the handle 3 and the pressing plate 2 when pressing powder, which can make the powder pressing operation smoother and more labor-saving; when the pressing plate 2 is pulled up and recovered, the handle 3 is folded, and the inner surface of the connecting portion 6 abuts against the upper part of the pressing plate 2, making the handle 3 more stable; at the same time, the holding portion 7 is arc-shaped, and its curvature is consistent with the curvature of the shell 1. When the handle 3 is folded, the holding portion 7 can be attached to the outer wall of the shell 1; the annular flange 12 is provided with a receiving groove 13, and when the handle 3 is folded, the receiving groove 13 is used to receive the holding portion 7.

[0035] The number of the handle 3 may be one or more. In the present embodiment, there are two handles 3 which are symmetrically arranged with the center of the pressing plate 2 as the axis, so as to facilitate operation after unfolding and storage after folding.

[0036] The opening 4 of the shell 1 is provided with a connecting ring 11 extending downward. When the shell 1 is installed and connected to the brewing funnel 8, the connecting ring 11 will extend into the brewing funnel 8, thereby blocking and sealing the gap between the shell 1 and the brewing funnel 8, thereby preventing coffee powder from splashing out of the gap when pressing the powder.

[0037] A first guide hole 14 and a second guide hole 15 are provided on the top of the shell 1 . The first guide hole 14 and the second guide hole 15 intersect vertically. The first guide hole 14 cooperates to realize the rotation of the connecting part 6 , and the second guide hole 15 cooperates to realize the movement of the gripping part 7 .

[0038] A sealing groove 16 is provided on the outer periphery of the pressing plate 2, and an elastic sealing member 17 is provided in the sealing groove 16 to prevent coffee powder from splashing out from the gap between the pressing plate 2 and the inner wall of the shell 1 when the coffee powder is pressed.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
