Description

Technical Field

[0001] The utility model relates to the technical field of coffee powder tampers, in particular to an impact powder hammer. Background Art

[0002] Pressing the coffee powder is a key step in the coffee powder extraction process. Pressing the coffee powder can form a flat surface in the powder bowl, which is conducive to extraction. In the prior art, the coffee powder is generally pressed by a powder tamper or an impact hammer, among which the impact hammer has a better effect of pressing the coffee powder.

[0003] However, in actual application, we found that the traditional impact hammer still has certain shortcomings. For example, when the traditional impact hammer is in use, the powder pressing plate is directly placed in the powder bowl and pressed on the coffee powder. In the powder pressing process, due to the influence of the force application angle, it is easy to cause pressure imbalance, which in turn affects the powder pressing effect. In addition, the traditional impact hammer has a closed structure and is not easy to disassemble in the event of a failure, making it difficult to repair. Utility Model Content

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Example:

[0037] See also Figure 1 -

[0038] Figure 5The impact hammer comprises a main barrel 1 and a powder pressing plate 2 arranged at the bottom end of the main barrel 1. In this embodiment, a connecting column is fixedly installed at the center of the top of the powder pressing plate 2, and the connecting column is threadedly connected to the inner wall of the bottom of the main barrel 1, so that the entire powder pressing plate 2 is detachable.

[0039] like Figure 3 As shown, an inner cylinder 3 is movably inserted in the main cylinder 1, and a pressing piece is provided at the top of the inner cylinder 3, through which the inner cylinder 3 can be pressed downward;

[0040] In this embodiment, the pressing piece is composed of a pressing head 4 and an outer tube 5 connected by threads. The pressing head 4 is threadedly connected to the top of the inner tube 3, and the outer tube 5 is movably sleeved on the outside of the main tube 1. In addition, a reset spring 21 is provided, which is sleeved on the outside of the inner tube 3 and is arranged between the top of the main tube 1 and the pressing head 4. Through the setting of the reset spring 21, the pressing piece can be easily reset by releasing the hand after being pressed.

[0041] In the present invention, a limited position mechanism is provided so that the inner cylinder 3 can move straight up and down in the main cylinder 1 and cannot rotate. For details, please refer to Figure 4 and Figure 5 The side wall of the main tube 1 is provided with a side groove 6, a stud 7 is installed in the inner thread of the side groove 6, and a limiting groove 8 matching with the stud 7 is vertically provided on the outer wall of the inner tube 3;

[0042] Therefore, by locking the stud 7 in the limiting groove 8 , the rotation of the inner tube 3 can be limited so that the inner tube 3 can only move in an up and down translation in the main tube 1 .

[0043] like Figure 3 As shown, an impact rod 9 is movably provided in the inner cylinder 3, and a support spring 11 is provided between the impact rod 9 and the pressing member. Specifically, the top end diameter of the impact rod 9 is reduced to form an upper bearing platform 10, and the support spring 11 is provided between the upper bearing platform 10 and the pressing member. Therefore, when the pressing member is pressed, if the position of the impact rod 9 remains unchanged, the support spring 11 will be compressed;

[0044] In this embodiment, Figure 5 As shown, a transverse groove 12 is formed through the impact rod 9, and locking rods 13 are provided at both ends of the transverse groove 12, and the two locking rods 13 are supported by an elastic support rod mechanism;

[0045] like Figure 4 As shown, a lower punching groove 15 is provided on the outer wall of the main cylinder 1, and side rod grooves 14 are provided on both sides of the top of the lower punching groove 15. When the two locking rods 13 are spread apart by the elastic support rod mechanism, the two ends of the two locking rods 13 are respectively located in the two side rod grooves 14. The trigger is provided on the inner cylinder 3, and when the inner cylinder 3 moves downward, it can force the two locking rods 13 to approach each other.

[0046] In the present invention, the trigger is a vertical slot 19 provided on the outer wall of the inner tube 3, and the vertical slot 19 is used for allowing the locking rod 13 to pass through. Figure 4 As shown, the top of the vertical groove 19 is inwardly curved to form an inwardly curved surface 20;

[0047] When not pressed, the end of the locking rod 13 is located in the side rod groove 14, the entire locking rod 13 is at the bottom end of the vertical groove 19, and the support spring 11 is also in the initial state;

[0048] When pressing, as the inner tube 3 gradually moves downward, the support spring 11 is gradually compressed (at this time, the position of the entire impact rod 9 remains unchanged, and the end of the locking rod 13 is locked in the side rod groove 14 to maintain the position);

[0049] When the inwardly-adducted surface 20 gradually contacts the locking rod 13, under the squeezing action of the inwardly-adducted surface 20, the two locking rods 13 will approach each other and gradually disengage from the side rod groove 14. After the two locking rods 13 disengage from the side rod groove 14, under the action of the restoring force of the supporting spring 11, the entire impact rod 9 will instantly move downward and impact on the powder pressing plate 2. Through the strong impact of the impact rod 9 on the powder pressing plate 2, the effect of impact-type powder pressing is achieved, the impact force is large, and the powder pressing effect is good.

[0050] In this embodiment, the elastic support rod mechanism includes a rod boss 16, a rod spring 17 and a pressing member 18. Figure 5 As shown, the two locking rods 13 are spread apart by the bottom hemispherical surface of the branch rod protrusion 16, and the branch rod protrusion 16 is vertically movably arranged in the branch rod groove, which is opened at the top of the impact rod 9, and the top opening of the branch rod groove is closed by a pressing member 18, and a branch rod spring 17 is also arranged between the bottom of the pressing member 18 and the top of the branch rod protrusion 16;

[0051] Thus, in the normal state, the rod spring 17 supports the rod boss 16 downward, and the rod boss 16 separates the two locking rods 13;

[0052] When the inwardly-adjusted inclined surface 20 squeezes the locking rod 13, the two locking rods 13 approach each other, which in turn pushes up the branch rod protrusion 16, thereby compressing the branch rod spring 17;

[0053] In this solution, the pressing member 18 is threadedly installed at the top opening of the branch rod slot, which can adjust the spring force and is also easy to disassemble.

[0054] like Figure 3 As shown, a sleeve 23 and an umbrella-shaped disc 24 are connected to each other, which are movably mounted on the main cylinder 1. Further, the diameter of the bottom end of the main cylinder 1 is reduced to form a sleeve portion 22, and a sleeve spring 25 is mounted on the sleeve portion 22. The bottom end of the sleeve spring 25 is blocked by the umbrella-shaped disc 24.

[0055] When in use, the powder pressing plate 2 is inserted into the powder bowl and pressed on the coffee powder, and the umbrella-shaped plate 24 is pressed on the edge of the powder bowl. During the pressing process, the umbrella-shaped plate 24 and the sleeve 23 can play a guiding role, effectively avoiding the powder pressing plate 2 from being biased and causing uneven powder pressing, thereby ensuring the powder pressing effect;

[0056] In the present invention, the bottom of the umbrella-shaped disk 24 is blocked by the powder pressing plate 2, thereby achieving an anti-falling effect. When the umbrella-shaped disk 24 is pushed up, the outer jacket spring 25 will be compressed.

[0057] In the utility model, all parts are of detachable modular design, which not only ensures stability during use, but also is easy to disassemble and repair.

[0058] 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.
