Description

Technical Field

[0001] This utility model relates to the field of coffee making tools, and in particular to an improved structure of a multi-functional coffee tamper. Background Technology

[0002] Distributing and tamping are two steps in coffee grinding. Distributing the coffee powder evenly in the portafilter, while tamping compacts it for easier coffee extraction. Currently, distributing and tamping can be done automatically by machine or manually by the user.

[0003] The automatic operation mode of the machine can be seen in Chinese invention patent application CN119366784A, entitled "A Fully Automatic Coffee Machine", published on January 28, 2025. It has a machine platform, on which a coffee bean grinder for grinding coffee beans into powder and a semi-automatic coffee machine for extracting coffee from the coffee powder are arranged. It also includes: a powder cup for holding coffee powder ground by the coffee bean grinder; a powder dispensing and tamping device, which has a powder dispensing component for dispensing coffee powder into the powder cup and a tamping component for tamping the dispensed coffee powder; and a conveying device for holding the powder cup and transferring the powder cup between the coffee bean grinder, the powder dispensing and tamping device and the semi-automatic coffee machine.

[0004] The manual operation method requires users to use a powder spreader and a powder presser separately. Not only does it require personnel to prepare two kinds of production tools, but the overall operation is also quite complicated and time-consuming. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an improved structure for a multi-functional powder press that has both powder pressing and powder dispensing functions and is relatively simple and convenient to operate.

[0006] The purpose of this utility model is achieved as follows:

[0007] An improved structure for a multi-functional powder tamper includes a clamping component and a pushing component. It is characterized by further including a base, a first spring, a second spring, and a bearing. The base is sleeved on the upper outer periphery of the clamping component via the bearing, with a gap between the base and the clamping component. The two ends of the first spring abut against the clamping component and the pushing component respectively, and the first spring is in a pre-tightened state. The pushing component is movably mounted on the clamping component, and the clamping component also has a limiting part for restricting the pushing component. The two ends of the second spring abut against the bearing and the pushing component respectively. In this improved structure for a multi-functional powder tamper, because the first spring is in a pre-tightened state, that is, the two ends of the first spring... The pressure and pushing components have significant frictional forces. When distributing coffee powder, the user only needs to rotate the pushing component, which, with the assistance of the first spring and bearing, drives the pressure component to rotate, thus distributing the powder. At the same time, the base will not affect the rotation of the pressure component. When tamping coffee powder, the user only needs to press the pushing component, which pushes the pressure component to move through the first spring, thus tamping the powder. In other words, this product has both tamping and distributing functions. Moreover, each time the powder is tamped, the user can press the pushing component to its limit position to ensure that the compression amount of the first spring is constant each time, so that the pressure of the first spring on the pressure component is constant, which helps to ensure the quality of the tamped coffee powder.

[0008] The objective of this utility model can also be achieved by the following technical measures:

[0009] Specifically, the clamping member includes a pressure head and a connecting column connected to the pressure head. The inner ring of the bearing is fitted around the outer circumference of the connecting column. The outer ring of the bearing is fixed on the base, and there is a gap between the base and the pressure head. The pushing member is movably disposed on the connecting column. The clamping member cooperates with the bearing through the connecting column, thereby realizing the installation and cooperation of the base and the bearing on the clamping member. Its design is ingenious.

[0010] Specifically, the pusher has an inner cavity, and a blocking wall with a through hole extends inward from the side wall of the inner cavity. The upper part of the connecting post passes through the through hole, and the upper outer periphery of the connecting post is provided with the limiting part, which abuts against the upper surface of the blocking wall. The limiting part and the blocking wall have a good cooperation effect, so as to stably realize the limiting effect of the limiting part on the pusher and prevent the pusher from disengaging from the connecting post under the action of the first spring. At the same time, the blocking wall passes through the through hole, so that the blocking wall will not affect the cooperation between the connecting post and the pusher.

[0011] Furthermore, an open retaining ring is provided on the upper outer periphery of the connecting column. The open retaining ring abuts against the upper surface of the blocking wall and constitutes the limiting part. The open retaining ring has a simple structure, is easy to obtain, and has a good implementation effect.

[0012] Specifically, the connecting column has a hollow cavity, the upper end of the pressure head has an inner groove, the lower part of the connecting column is inserted into the inner groove, and the first spring is placed in the hollow cavity of the connecting column with its upper and lower ends abutting against the top surface of the inner cavity of the pusher and the inner groove, respectively. This ensures that the two ends of the first spring stably abut against the inner cavity of the pusher and the pressure head, respectively. At the same time, the hollow cavity of the connecting column provides a good limiting effect for the spring, which is conducive to the stable operation of the first spring. Furthermore, the installation and operation of the connecting column on the pressure head is simple and convenient.

[0013] Specifically, the pushing component includes a hollow shell and a pushing cover. The inner sidewall 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 pushing cover and the hollow shell form the inner cavity. The upper end of the first spring abuts against the pushing cover. On the one hand, the structure of the pushing cover and the hollow shell is simple and easy to implement. On the other hand, the user only needs to disassemble the pushing cover to maintain or replace the first spring, which is simple and convenient to operate.

[0014] Specifically, the second spring is a V-shaped spring that is wider at the top and narrower at the bottom. The lower surface of the blocking wall has an annular groove that is recessed upwards. The upper end of the V-shaped spring abuts against the top surface of the annular groove, and the lower end of the V-shaped spring abuts against the inner ring of the bearing. In the initial state, the base and the bearing can remain fixed relative to the pushing member under the action of the second spring, avoiding the base from being in a state of easy movement, which is conducive to the stable fit between the base and the coffee powder cup when dispensing powder.

[0015] Specifically, the base includes a connecting bottom wall and an outer ring and an inner ring connected to both ends of the connecting bottom wall. The lower end of the pusher extends into the outer ring. The inner ring 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-fitted 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, corresponding to the inner ring of the bearing. The inner ring of the bearing rests on the second support platform. The height of the first support platform is lower than the height of the second support platform. This ensures 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 can restrict the movement of the pusher to a certain extent, which is beneficial to the stable movement of the pusher. Moreover, the connecting bottom wall can limit the maximum travel of the pusher. That is, each time the user uses it, the user can press the lower end of the pusher until it abuts against the connecting bottom wall. At this time, the compression of the first spring is constant, so as to achieve constant pressure of the pusher each time the powder is pressed.

[0016] Furthermore, the outer periphery of the base is also connected to a movable hollow adjusting sleeve, and the lower surface of the pressing member is lower than the lower surface of the hollow adjusting sleeve. In use, the base is fitted with the opening periphery of the coffee powder cup through the hollow adjusting sleeve, so that the lower surface of the pressing member extends into the coffee powder cup. The hollow adjusting sleeve is operated to move on the base, thereby adjusting the height difference between the lower surface of the hollow adjusting sleeve and the lower surface of the pressing member, that is, adjusting the height of the lower surface of the pressing member extending into the coffee powder cup to meet the usage requirements of different powder distribution depths.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) This multi-functional coffee tamper has an improved structure. Since the first spring is in a pre-tightened state, the two ends of the first spring have a large friction with the clamping part and the pushing part respectively. When dispensing coffee powder, the user only needs to rotate the pushing part and, with the assistance of the first spring and the bearing, can drive the clamping part to rotate and achieve the dispensing of coffee powder. At the same time, the base will not affect the rotation of the clamping part. When tamping coffee powder, the user only needs to press the pushing part so that the pushing part pushes the clamping part to move through the first spring and achieves the tamping of coffee powder. In other words, this product has the functions of tamping and dispensing coffee powder. Moreover, each time the coffee powder is tamped, the user can press the pushing part to the limit position so that the compression amount of the first spring is constant each time, so that the pressure of the first spring on the clamping part is constant, which is conducive to ensuring the quality of the coffee powder after tamping.

[0019] (2) On the one hand, the structure of the push cover and the hollow shell is simple and easy to implement. On the other hand, users only need to disassemble the push cover to maintain or replace the first spring, which is simple and convenient to operate.

[0020] (3) When in use, the base is fitted with the opening periphery of the coffee powder cup through the hollow adjustment sleeve, so that the lower surface of the pressing part extends into the coffee powder cup. The hollow adjustment sleeve is operated to move on the base, thereby adjusting the height difference between the lower surface of the hollow adjustment sleeve and the lower surface of the pressing part. That is, the height of the lower surface of the pressing part extending into the coffee powder cup is adjusted to meet the usage requirements of different powder distribution depths.

[0031] As a more specific embodiment, the connecting post 13 has a hollow cavity 131, the upper end of the pressure head 12 is provided with an inner groove 121, the lower part of the connecting post 13 is inserted into the inner groove 121, the first spring 4 is placed in the hollow cavity 131 of the connecting post 13 and the upper and lower ends of the first spring 4 abut against the top surface of the inner cavity 21 of the pusher 2 and the inner groove 121 respectively; more specifically, the lower outer periphery of the connecting post 13 and the inner periphery of the inner groove 121 are provided with screw threads that are screwed together, so that the connection between the lower outer periphery of the connecting post 13 and the inner groove 121 is more secure.

[0032] In this embodiment, the pushing member 2 includes a hollow shell 24 and a pushing cover 25. The inner sidewall of the hollow shell 24 is provided with the blocking wall 22. The pushing cover 25 is connected to the upper part of the hollow shell 24 and the pushing cover 25 and the hollow shell 24 form the inner cavity 21. The upper end of the first spring 4 abuts against the pushing cover 25.
