[0002] Distributing the coffee powder and tamping the coffee powder are two processes in grinding coffee. The purpose of distributing the coffee powder is to make the coffee powder evenly distributed in the powder bowl, and the purpose of tamping the coffee powder is to make the coffee powder compact in the powder bowl to facilitate the subsequent coffee making. The existing distributing and tamping operations generally have two modes: automatic machine operation or manual operation by the user.

[0003] The automatic operation mode of the machine can be seen in Chinese invention patent application CN119366784A, title: A fully automatic coffee machine, application publication date: January 28, 2025, which has a machine table, on the table top of the machine table is provided with a coffee bean grinder for grinding coffee beans into powder and a semi-automatic coffee machine for extracting coffee from coffee powder, and also includes: a powder cup for holding coffee powder ground by the coffee bean grinder; a powder distribution and pressing device, which has a powder distribution component for distributing the coffee powder in the powder cup and a pressing component for compacting the coffee powder after distributing the powder; a conveying device for clamping the powder cup and transferring the powder cup between the coffee bean grinder, the powder distribution and pressing device and the semi-automatic coffee machine.

[0004] The manual operation method requires the user to use a powder distributor and a powder press respectively, which not only requires personnel to prepare two production tools, but also the overall operation is relatively complicated and time-consuming. Summary of the invention

[0005] The purpose of the present invention is to solve the deficiencies of the above-mentioned prior art and to provide a multifunctional powder pressing device which has the functions of pressing and distributing powder and is relatively simple and convenient to operate.

[0006] The object of the present invention is achieved in that: A multifunctional powder press, comprising a pressing member and a pushing member, characterized in that it also comprises a base, a first spring, a second spring and a bearing, the base is sleeved on the upper periphery of the pressing member through the bearing and there is a gap between the base and the pressing member, the periphery of the base is also connected to a movable hollow adjustment sleeve, the lower surface of the pressing member is lower than the lower surface of the hollow adjustment sleeve, the two ends of the first spring are respectively against the pressing member and the pushing member and the first spring is in a pre-tightened state, the pushing member is movably arranged on the pressing member and a limiting portion for limiting the pushing member is also arranged on the pressing member, and the two ends of the second spring are respectively against the bearing and the pushing member; in this multifunctional powder press, since the first spring is in a pre-tightened state, that is, the two ends of the first spring have a large friction force with the pressing member and the pushing member respectively, when spreading powder, the user only needs to rotate the pushing member, and can drive the pressing member with the assistance of the first spring and the bearing. The user only needs to press the push member to make the push member push the pressing member to move through the first spring to achieve powder compression, that is, the product has the functions of powder compression and powder distribution, and each time the powder is compressed, the user can press the push member to the limit position to make the compression amount of the first spring constant each time, so that the pressure of the first spring on the pressing member is constant, which is beneficial to ensure the quality of the coffee powder after compression; furthermore, when in use, the base is matched with the opening periphery of the coffee powder cup through the hollow adjustment sleeve, so that the lower surface of the pressing member extends into the coffee powder cup, and the hollow adjustment sleeve is operated to realize the movement of the hollow adjustment sleeve on the base, thereby realizing the adjustment of the height difference between the lower surface of the hollow adjustment sleeve and the lower surface of the pressing member, that is, realizing the height adjustment of the lower surface of the pressing member extending into the coffee powder cup to meet the use requirements of different powder distribution depths.

[0007] The purpose of the present invention can also be solved by the following technical measures: Specifically, the clamping member includes a pressure head and a connecting column connected to the pressure head, the inner ring of the bearing is sleeved on the outer periphery of the connecting column, the outer ring of the bearing is fixed on the base and there is the gap between the base and the pressure head, and the pushing member is movably arranged on the connecting column; the clamping member is matched with the bearing through the connecting column, and then the base and the bearing are installed and matched on the clamping member, and the arrangement is ingenious.

[0008] Specifically, an inner cavity is provided in the pushing member, and a blocking wall with a through hole is extended inward from the side wall of the inner cavity, the upper part of the connecting column passes through the through hole, and the limiting part is provided on the upper periphery of the connecting column, and the limiting part is abutted against the upper surface of the blocking wall; the limiting part and the blocking wall have a good coordination effect, so as to stably realize the limiting effect of the limiting part on the pushing member, and prevent the pushing member from detaching from the connecting column under the action of the first spring, and at the same time, the blocking wall passes through the through hole thereon, so that the blocking wall will not affect the coordination between the connecting column and the pushing member.

[0009] Specifically, an opening retaining ring is arranged on the upper periphery of the connecting column, the opening retaining ring abuts against the upper surface of the blocking wall, and the opening retaining ring constitutes the limiting portion; the opening retaining ring has a simple structure, is easy to obtain and has a good implementation effect.

[0010] Specifically, a hollow cavity is opened on the connecting column, an inner groove is arranged at the upper end of the pressure head, the lower part of the connecting column is inserted into the inner groove, the first spring is placed in the hollow cavity of the connecting column and the upper and lower ends of the first spring are respectively against the top surface of the inner cavity of the pushing member and the inner groove; so that the two ends of the first spring are respectively against the inner cavity of the pushing member and the pressure head stably, and at the same time, the hollow cavity of the connecting column has a better limiting effect on the spring, which is beneficial to the stable operation of the first spring. Furthermore, the installation operation of the connecting column on the pressure head is simple and convenient.

[0011] Specifically, the pushing member includes a hollow shell and a pushing cover, the inner side wall of the hollow shell is provided with the blocking wall, the pushing cover is connected to the upper part of the hollow shell and the inner cavity is formed between the pushing cover and the hollow shell, and the upper end of the first spring is against the pushing cover; on the one hand, the structure of the pushing cover and the hollow shell is simple and easy to implement, and on the other hand, the user only needs to remove the pushing cover to maintain or replace the first spring, and the operation is simple and convenient.

[0012] Specifically, the second spring is a V-shaped spring which is wider at the top and narrower at the bottom, the lower surface of the blocking wall is concave with an annular groove, the upper end of the V-shaped spring is against the top surface of the annular groove, and the lower end of the V-shaped spring is against the inner ring of the bearing; in the initial state, the base together with the bearing can be kept in a fixed state relative to the pushing member under the action of the second spring, so as to prevent the base from being easily movable, which is beneficial to the stable cooperation between the base and the coffee powder cup when distributing the coffee powder.

[0013] Specifically, the base includes a connecting bottom wall and an outer ring portion and an inner ring portion connected at both ends of the connecting bottom wall, the lower end of the pushing member extends into the outer ring portion, the inner ring portion extends inwardly with a first support, and the bottom surface of the first support is flush with the bottom surface of the connecting bottom wall, the outer ring of the bearing is interference fit with the first support, and a second support is also provided on the pressure head located on the outer periphery of the connecting column at a position corresponding to the inner ring of the bearing, the inner ring of the bearing is supported on the second support, and the height of the first support is lower than the height of the second support; so that there is a gap between the bottom surface of the base and the surface of the pressure head, and at the same time, the outer ring portion can play a certain limiting role in the movement of the pushing member, which is beneficial to the stable movement of the pushing member, and the connecting bottom wall can limit the maximum moving stroke of the pushing member, that is, each time the user uses it, the user can press the lower end of the pushing member until it is against the connecting bottom wall. At this time, the compression amount of the first spring is constant, so that a constant pressure of the pushing member is achieved each time the powder is pressed.

[0014] Specifically, a powder cloth sheet is further included, and the powder cloth sheet is detachably connected to the lower surface of the pressure head, so that the user can replace the powder cloth sheets with different shapes.

[0015] The beneficial effects of the present invention are as follows: (1) This multifunctional powder pressing device has a first spring in a pre-tightened state, that is, the two ends of the first spring have a large friction with the pressing member and the pushing member respectively. When spreading powder, the user only needs to rotate the pushing member, and with the assistance of the first spring and the bearing, the pressing member can be driven to rotate and the powder can be spread. At the same time, the base will not affect the rotation of the pressing member. When compacting powder, the user only needs to press the pushing member, so that the pushing member pushes the pressing member to move through the first spring to compact the powder. That is, this product has the functions of compacting and distributing powder. Moreover, each time the powder is compacted, the user can press the pushing member to the limit position. The arrangement is such that the compression amount of the first spring is constant each time, so that the pressure exerted by the first spring on the pressing member is constant, which is beneficial to ensuring the quality of the coffee powder after pressing. Furthermore, when in use, the base cooperates with the opening periphery of the coffee powder cup through the hollow adjustment sleeve, so that the lower surface of the pressing member extends into the coffee powder cup, and the hollow adjustment sleeve is operated to realize the movement of the hollow adjustment sleeve on the base, thereby realizing the adjustment of the height difference between the lower surface of the hollow adjustment sleeve and the lower surface of the pressing member, that is, realizing the height adjustment of the lower surface of the pressing member extending into the coffee powder cup to meet the use requirements of different powder distribution depths.

[0016] (2) The cooperation effect between the limiting part and the blocking wall is good, so as to stably realize the limiting effect of the limiting part on the pushing member, and prevent the pushing member from being separated from the connecting column under the action of the first spring. At the same time, the blocking wall passes through the through hole thereon, so that the blocking wall does not affect the cooperation between the connecting column and the pushing member.

[0017] (3) The base includes a connecting bottom wall and an outer ring portion and an inner ring portion connected at both ends of the connecting bottom wall. The lower end of the pusher extends into the outer ring portion. The inner ring portion extends inward to form a first support platform, and the bottom surface of the first support platform is flush with the bottom surface of the connecting bottom wall. The outer ring of the bearing is interference fit with the first support platform. A second support platform is also provided on the pressure head located on the outer periphery of the connecting column at a position corresponding to the inner ring of the bearing. The inner ring of the bearing is supported on the second support platform, and the height of the first support platform is lower than that of the first support platform; so that there is a gap between the bottom surface of the base and the surface of the pressure head. At the same time, the outer ring portion can play a certain limiting role in the movement of the pusher, which is conducive to the stable movement of the pusher. Moreover, the connecting bottom wall can limit the maximum movement stroke of the pusher, that is, each time the user uses it, the user can press the lower end of the pusher until it is against the connecting bottom wall. At this time, the compression amount of the first spring is constant, so that a constant pressure of the pusher is achieved each time the powder is pressed. BRIEF DESCRIPTION OF THE DRAWINGS
