In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0035] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] Refer to the following Figure 1-Figure 13 A powder hammer storage structure according to some embodiments of the present application is described.

[0037] The purpose of this technical solution is to improve the user experience and convenience of the powder hammer. By adopting a specific structure and design, the powder hammer can be effectively stored on the machine body and can be guaranteed to be safe and reliable during use.

[0038] A compacting hammer storage structure, wherein a forward-convex machine head 2 is provided on the upper part of a machine body 1, a storage slot 3 is provided at the bottom of the machine head 2, a compacting hammer 4 comprises a gripping portion 5 and a pressing plate portion 6 connected to each other, a clamping slot 7 is provided on the outer wall of the gripping portion 5, and a clamping piece matched with the clamping slot 7 is provided on the inner wall of the storage slot 3; when the gripping portion 5 of the compacting hammer 4 is inserted into the storage slot 3, the clamping slot 7 is clamped with the clamping piece so that the gripping portion 5 is kept in the storage slot 3, thereby completing the storage of the compacting hammer 3 on the machine body 1; and when the compacting hammer 4 needs to be used, the pressing plate portion 6 exposed outside the storage slot 3 is pulled to drive the gripping portion 5 to separate the clamping slot 7 from the clamping piece, and the gripping portion 5 is taken out of the storage slot 3. The above-mentioned machine body 1 can be a corresponding machine body of a coffee machine or a grinder.

[0039] In the present technical solution, a retaining spring can be used as a clamping member. A retaining spring groove is provided on the inner wall of the receiving groove 3. The retaining spring is arranged in the retaining spring groove. The clamping portion 10 of the retaining spring passes through the retaining spring groove and extends into the clamping groove 7 to realize the clamping and fixing of the holding portion 5.

[0040] In Example 1, a first retaining spring groove 8 located at the same horizontal plane as the retaining groove 7 is provided on the inner wall of the receiving groove 3, a first retaining spring 9 is arranged in the first retaining spring groove 8, and a clamping portion 10 of the first retaining spring 9 passes through the first retaining spring groove 8 and extends into the retaining groove 7.

[0041] In Example 2, a second retaining spring groove 11 perpendicular to the horizontal plane where the retaining groove 7 is located is provided on the inner wall of the receiving groove 3, and a second retaining spring 12 is arranged in the second retaining spring groove 11. The clamping portion 10 of the second retaining spring 12 passes through the second retaining spring groove 11 and extends into the retaining groove 7.

[0042] The width of the clamping portion 10 of the first clamping spring 9 or the second clamping spring 12 is smaller than the radial spacing of the slot 7, which can not only maintain the effective clamping of the slot 7 by the clamping portion 10, but also allow the clamping portion 10 to produce elastic deformation and release the slot 7 under sufficient external force.

[0043] In Example 3, the clamping member uses a positioning bead 13, which is located at the same horizontal plane as the clamping slot 7. The ball 14 of the positioning bead 13 is extended into the clamping slot 7 by the action of the spring inside the positioning bead 13. When the gripping portion 5 is inserted or pulled out, the ball 14 is compressed or ejected to achieve separation or clamping with the clamping slot 7. In order to obtain a better clamping effect, at least two positioning beads 13 are provided.

[0044] In Embodiment 4, the clamping member adopts a clamping claw 15 arranged along the inner wall of the receiving groove 3 in the circumferential direction, and a convex tooth 16 is arranged on the inner side of the bottom of the clamping claw 15, and the convex tooth 16 is clamped into the clamping groove 7; a clearance groove 17 is arranged between the two sides and the bottom of the clamping claw 15 and the inner wall of the receiving groove 3; when the gripping part 5 is inserted or pulled out, the convex tooth 16 is pushed out or retracted into the clamping groove 7, so as to achieve the retention or removal of the gripping part 5 in the receiving groove 3. In order to obtain a better clamping effect, at least two clamping claws are provided; in Embodiment 4, there are three clamping claws, which are spaced and distributed along the inner wall of the receiving groove 3 in the circumferential direction.

[0045] After adopting the storage structure of the above-mentioned card slot and the card connector, not only the efficiency and safety of the powder hammer are improved, but also more usage options and usage methods are provided. At the same time, it overcomes the problem that when using a magnetic structure, stainless steel materials with high food contact safety cannot be used for the powder hammer and the storage slot due to the natural weak magnetism of stainless steel materials, which affects the use effect and experience.

[0046] 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.
