[0001] The present disclosure relates to the field of coffee processing tools, and in particular to a quantifiable pressure tamper and a coffee tamper. Background Art

[0002] At present, with the popularization of coffee culture and consumers' pursuit of coffee quality, coffee tamper plays an increasingly important role in the coffee making process. When coffee powder is tamped, the difference in the uniformity of the powder will directly affect the feel of the coffee, and some manufacturers have also discovered this problem.

[0003] For example, Chinese patent document CN206197774U discloses an impact-type constant-pressure coffee powder tamper, which includes a handle and an impact constant-force mechanism. The impact constant-force mechanism includes a pressing cylinder, a pressing block, a slider, a sliding sleeve and an ejector. The slider is provided with a slider spring, and the ejector is provided with an ejector spring; one end of the pressing cylinder is connected to the handle, and the other end of the pressing cylinder is connected to the sliding sleeve; the sliding sleeve is connected to the pressing block; the slider is provided in the pressing cylinder; and the ejector is fixed to the pressing block by the ejector spring.

[0004] However, the design of the above-mentioned impact type constant pressure coffee tamper still has the following problems:

[0005] The above-mentioned impact-type constant-pressure coffee tamper, although it ensures constant control of the force when tamping the coffee powder through the connection between the tamping cylinder and the slider spring, when tamping the coffee powder, because the pressure of the coffee tamper on the coffee powder is constant, the tamper cannot adjust the tamping depth according to the pressure, resulting in the extraction style of the coffee powder after tamping being roughly the same. Utility Model Content

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a quantifiable pressure powder tamping hammer and a coffee powder tamping hammer that can control the depth of powder tamping and adjust the strength of powder tamping.

[0007] The purpose of this disclosure is achieved through the following technical solutions:

[0008] A quantifiable pressure powder compacting hammer, comprising a powder compacting block, a compacting cover, a push rod and a compacting handle;

[0009] The pressure cover is provided with a guide slide hole, and the rod body of the push rod slides through the guide slide hole; the powder pressing block and the pressing handle are respectively arranged at two ends of the push rod;

[0010] The quantifiable pressure powder compacting hammer also includes a pressure measuring component;

[0011] The pressure measuring assembly comprises an adjusting sleeve, an elastic reset member and a measuring and fixing sleeve; the adjusting sleeve is sleeved between the pressure cover and the pressure handle, and the push rod is inserted into the inner sleeve of the adjusting sleeve; the inner sleeve of the adjusting sleeve is divided into a rotating chamber, a telescopic sliding chamber and a receiving chamber which are connected in sequence; the receiving chamber is arranged close to the pressure cover, and the measuring and fixing sleeve is slidably arranged in the receiving chamber; the measuring and fixing sleeve is slidably sleeved on the push rod and connected to the pressure cover;

[0012] The rotating cavity is arranged close to the pressing handle, and the cavity wall of the rotating cavity is threadedly screwed to the peripheral wall of the push rod; the elastic reset member is arranged in the telescopic sliding cavity, and the adjusting sleeve is supported on the measuring cylinder through the elastic reset member.

[0013] In one of the embodiments, scale lines are provided on the outer cylinder wall of the measuring cylinder, and the length direction of the scale lines is the same as the sliding direction of the adjusting sleeve.

[0014] In one of the embodiments, the outer peripheral wall of the adjusting sleeve is provided with a circle of anti-slip grooves protruding outwards.

[0015] In one of the embodiments, a connecting groove is provided on the pressing handle; one end of the push rod is arranged in the connecting groove and is screwed to the bottom of the connecting groove; a guide gap is formed between the push rod and the peripheral wall of the connecting groove, and the adjusting sleeve extends into the guide gap to form a guide boss.

[0016] In one embodiment, the elastic reset member is a compression spring, and the compression spring is sleeved on the push rod.

[0017] In one embodiment, an internal thread is provided on the cavity wall of the rotating cavity, and an external thread is provided on the peripheral wall of the push rod, and the internal thread matches the external thread.

[0018] In one embodiment, the pressing handle is provided with a gripping structure at one end away from the push rod.

[0019] In one of the embodiments, the pressing handle is provided with a top-pressing limit block, and the adjusting sleeve is close to the pressing handle and presses against the top-pressing limit block.

[0020] In one of the embodiments, the periphery of the pressing cover protrudes from the compressed powder block.

[0021] A coffee tamper comprises a coffee tamper and a quantifiable pressure tamper of any one of the above embodiments.

[0022] Compared with the prior art, the present invention has at least the following advantages:

[0023] 1) The measuring cylinder is slidably arranged in the accommodating cavity, the measuring cylinder is slidably sleeved on the push rod, and the elastic reset member is arranged in the telescopic sliding cavity, so that the adjusting sleeve is pressed against the measuring cylinder through the elastic reset member. Because the cavity wall of the rotating cavity is threadedly connected to the peripheral wall of the push rod, the user can rotate the adjusting sleeve to stretch or shrink the elastic reset member in the telescopic sliding cavity. When the elastic reset member stretches, the pressure of the elastic reset member decreases, and the pressure transmitted to the measuring cylinder will decrease. When the elastic reset member shrinks, the pressure of the elastic reset member increases, and the pressure transmitted to the measuring cylinder will increase, so that the pressure on the measuring cylinder can be adjusted. The measuring cylinder is connected to the pressure cover. When the pressure cover presses against the coffee powder, the pressure of the pressure cover pressing against the coffee powder can also be adjusted.

[0024] 2) Compared with the impact-type constant-pressure coffee tamper in the prior art, the above-mentioned quantifiable pressure tamper causes the elastic reset part to move after the adjustment sleeve rotates. When the elastic reset part moves, it drives the movement of the push rod, so that the depth of coffee powder pressed by the tamper can be adjusted by rotation, and finally different depths of coffee powder pressed are achieved, and the best extraction style of different coffee powder can be achieved according to the depth of coffee powder pressed.

DETAILED DESCRIPTION

[0030] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0034] like Figure 1 to Figure 2As shown, a quantifiable pressure powder compacting hammer 10 of an embodiment includes a powder compacting block 200, a pressing cover 400, a push rod 300 and a pressing handle 500; a guide slide hole 410 is opened on the pressing cover 400, and the rod body of the push rod 300 slides through the guide slide hole 410; the powder compacting block 200 and the pressing handle 500 are respectively arranged at both ends of the push rod 300; the quantifiable pressure powder compacting hammer 10 also includes a pressure measuring assembly 100; the pressure measuring assembly 100 includes an adjusting sleeve 110, an elastic reset member 120 and a measuring cylinder 130; the adjusting sleeve 110 is sleeved between the pressing cover 400 and the pressing handle 500, and the push rod 300 is inserted into the adjusting sleeve 1 10; the inner cylinder of the adjusting sleeve 110 is divided into a rotating chamber 1110, a telescopic sliding chamber 1120 and a accommodating chamber 1130 which are connected in sequence; the accommodating chamber 1130 is arranged close to the pressure cover 400, and the measuring and fixing cylinder 130 is slidably arranged in the accommodating chamber 1130; the measuring and fixing cylinder 130 is slidably sleeved on the push rod 300 and connected to the pressure cover 400; the rotating chamber 1110 is arranged close to the pressure handle 500, and the cavity wall of the rotating chamber 1110 is threadedly screwed to the peripheral wall of the push rod 300; the elastic reset member 120 is arranged in the telescopic sliding chamber 1120, and the adjusting sleeve 110 is held against the measuring and fixing cylinder 130 through the elastic reset member 120.

[0035] It can be understood that by sliding the measuring cylinder 130 in the accommodating cavity 1130 , slidingly sleeved on the push rod 300 , and disposing the elastic return member 120 in the telescopic sliding cavity 1120 , the adjusting sleeve 110 is supported against the measuring cylinder 130 through the elastic return member 120 . Because the wall of the rotating chamber 1110 is threadedly connected to the peripheral wall of the push rod 300, the user can rotate the adjusting sleeve 110 to stretch or shrink the elastic reset member 120 in the telescopic sliding chamber 1120. When the elastic reset member 120 is stretched, the pressure of the elastic reset member 120 is reduced, and the pressure transmitted to the measuring cylinder 130 is reduced. When the elastic reset member 120 is contracted, the pressure of the elastic reset member 120 is increased, and the pressure transmitted to the measuring cylinder 130 is increased, thereby adjusting the pressure on the measuring cylinder 130. The measuring cylinder 130 is connected to the pressure cover 400. When the pressure cover 400 presses against the coffee powder, the pressure of the pressure cover 400 pressing against the coffee powder can also be adjusted.

[0036] It can be understood that, compared with the impact-type constant-pressure coffee powder tamping device in the prior art, the above-mentioned quantifiable pressure powder tamping hammer 10 causes the elastic reset member 120 to move accordingly after the adjustment sleeve 110 rotates. When the elastic reset member 120 moves accordingly, it drives the movement of the push rod 300, so that the powder tamping depth of the coffee powder by the powder tamping hammer can be adjusted by rotation, and finally different powder tamping depths of different coffee powders are achieved, and the best extraction style of different coffee powders can be achieved according to the powder tamping depth.

[0037] like Figure 1 to Figure 2As shown, specifically, a scale line 1310 is provided on the outer cylinder wall of the measuring cylinder 130, and the length direction of the scale line 1310 is the same as the sliding direction of the adjusting sleeve 110. It can be understood that by providing the scale line 1310 on the measuring cylinder 130, the length direction of the scale line 1310 is consistent with the sliding direction of the adjusting sleeve 110. When the adjusting sleeve 110 is twisted, the elastic reset member 120 will slide up and down relative to the measuring cylinder 130 according to the tensile pressure, so that the scale line 1310 of the measuring cylinder 130 changes accordingly. According to the change of the scale line 1310 of the measuring cylinder 130, the elastic reset member 120 can be intuitively and clearly seen. The change of the pressure of the pressure cap 400 on the pressed powder block 200 can be intuitively felt. Designing the scale line 1310 on the measuring cylinder 130 allows the barista to clearly record the pressed powder scale line 1310 of each type of coffee powder, ensuring the extraction style required by different coffee powders.

[0038] like Figure 1 As shown, further, the outer peripheral wall of the adjusting sleeve 110 is convexly provided with a circle of anti-skid lines 1140. It can be understood that by providing the anti-skid lines 1140 on the outer peripheral wall of the adjusting sleeve 110, when the user rotates and twists the adjusting sleeve 110, by twisting the area of ​​the adjusting sleeve 110 with the anti-skid lines 1140, the friction force when the user twists is increased, and it is prevented that the friction force is too small when twisting the adjusting sleeve 110 during powder compaction, resulting in slipping of the hand and making it more difficult to control the twisting force, and adding the anti-skid lines 1140 prevents the user from slipping when twisting the adjusting sleeve 110 during powder compaction.

[0039] like Figure 2 As shown, specifically, a connecting groove 510 is opened on the pressing handle 500; one end of the push rod 300 is arranged in the connecting groove 510 and is screwed to the bottom of the connecting groove 510; a guide gap 310 is formed between the push rod 300 and the peripheral wall of the connecting groove 510, and the adjusting sleeve 110 extends into the guide gap 310 and forms a guide boss 1150. It can be understood that by opening a connecting groove 510 on the pressing handle 500, setting a connecting groove 510 on the push rod 300, and forming a guide gap 310 on the peripheral wall, the adjusting sleeve 110 extends along the guide gap 310 to form a guide boss 1150, and one end of the push rod 300 is set in the connecting groove 510 and the adjusting sleeve 110 extends toward the guide gap 310 to form the guide boss 1150, so that the push rod 300 connects the pressing handle 500 and the adjusting sleeve 110 together. When the adjusting sleeve 110 is twisted, the push rod 300 connects the pressing handle 500 and the adjusting sleeve 110, so that the adjusting sleeve 110 and the pressing handle 500 can be firmly fixed on the same vertical plane as the push rod 300, thereby avoiding the relative tilting and separation of the pressing handle 500 and the adjusting sleeve 110 due to the pressure of the elastic reset member 120 and the twisting of the adjusting sleeve 110.

[0040] like Figure 2 As shown, in one embodiment, the elastic reset member 120 is a compression spring 1210, and the compression spring 1210 is sleeved on the push rod 300. It can be understood that by setting the elastic reset member 120 as a compression spring 1210, and the compression spring 1210 is sleeved in the push rod 300, when the adjusting sleeve 110 is rotated, the compression spring 1210 expands and contracts the length of the compression spring 1210 as the adjusting sleeve 110 rotates, so that the change in the length of the compression spring 1210 drives the pressure of the push rod 300 on the gland 400, and the expansion and contraction of the compression spring 1210 changes the stroke change of the push rod 300, so that the adjusting sleeve 110 can control the pressing depth of the coffee powder. At the same time, by sleeved on the push rod 300, the adjusting sleeve 110 can be reset as the expansion and contraction distance of the compression spring 1210.

[0041] like Figure 2 As shown, in one embodiment, an internal thread 1111 is provided on the cavity wall of the rotating cavity 1110, and an external thread 320 is provided on the peripheral wall of the push rod 300, and the internal thread 1111 cooperates with the external thread 320. It can be understood that by providing the internal thread 1111 on the cavity wall of the rotating cavity 1110, and providing the external thread 320 on the peripheral wall of the push rod 300, the internal thread 1111 cooperates with the external thread 320 to be threadedly connected, so that the adjusting sleeve 110 can be adjusted up and down according to the external thread 320 in the push rod 300, and the setting of the external thread 320 in the push rod 300 ensures that the push rod 300 can be connected to the adjusting sleeve 110 in a stable sliding manner, and the cooperation of the external thread 320 and the internal thread 1111 ensures that the push rod 300 and the adjusting sleeve 110 are consistently maintained on the vertical plane of the gland 400.

[0042] like Figure 3 As shown, further, the pressing handle 500 is provided with a gripping structure 530 at one end away from the push rod 300. It can be understood that the pressing handle 500 is provided with the gripping structure 530, and the gripping structure 530 is provided with an uneven groove. By providing the gripping structure 530 on the pressing handle 500, when the user is compacting the powder, the user can easily grasp the groove in the pressing handle 500 so that the quantifiable pressure compacting hammer 10 does not shake easily, and it is easier to hold the device.

[0043] like Figure 2As shown, specifically, the pressing handle 500 is provided with a top-pressing limit block 520, and the adjusting sleeve 110 is close to the pressing handle 500 and presses against the top-pressing limit block 520. It can be understood that by providing the top-pressing limit block 520 on the pressing handle 500, the adjusting sleeve 110 is close to the pressing handle 500 and presses against the top-pressing limit block 520, when the adjusting sleeve 110 is turned to adjust the compression spring 1210, when the adjusting sleeve 110 is upwardly close to the pressing handle 500, the top-pressing limit block 520 controls the maximum stroke of the adjusting sleeve 110 to rotate, thereby achieving the maximum telescopic distance of the compression spring 1210.

[0044] like Figures 2 to 3 As shown, specifically, the periphery of the pressure cap 400 protrudes from the compressed powder block 200. It can be understood that the periphery of the pressure cap 400 protrudes from the compressed powder block 200, the pressure cap 400 is arranged on the top of the compressed powder block 200, the pressure cap 400 is pressed on the compressed powder block 200, the pressure cap 400 fully covers the top of the compressed powder block 200, the clearance pressure cap 400 covers the compressed powder block 200 and the periphery of the pressure cap 400 protrudes from the compressed powder block 200, so that when the adjusting sleeve 110 adjusts the compression spring 1210, the pressure of the push rod 300 on the pressure cap 400 can act evenly on the compressed powder block 200, so that the compressed powder block 200 can press the coffee powder evenly, ensuring that the density of the compressed coffee powder is consistent, so that the extraction effect of the coffee powder is better.

[0045] The present application also provides a coffee tamper, comprising the quantifiable pressure tamper 10 of any of the above embodiments. It can be understood that by applying the quantifiable pressure tamper 10 of the present disclosure to the coffee tamper, when the adjusting sleeve 110 is rotated, the pressure of the push rod 300 on the pressing cover 400 is changed by controlling the telescopic length of the elastic reset member 120, so that the pressure of the tamper block 200 on the coffee powder can be adjusted according to the demand, so that the extraction effect of the coffee powder is optimized.

[0046] Compared with the prior art, the present invention has at least the following advantages:

[0047] 1) The measuring and fixing cylinder 130 is slidably disposed in the accommodating cavity 1130 , and the measuring and fixing cylinder 130 is slidably sleeved on the push rod 300 , and the elastic reset member 120 is disposed in the telescopic sliding cavity 1120 , so that the adjusting sleeve 110 is supported against the measuring and fixing cylinder 130 through the elastic reset member 120 . Because the wall of the rotating chamber 1110 is threadedly connected to the peripheral wall of the push rod 300, the user can rotate the adjusting sleeve 110 to stretch or shrink the elastic reset member 120 in the telescopic sliding chamber 1120. When the elastic reset member 120 is stretched, the pressure of the elastic reset member 120 is reduced, and the pressure transmitted to the measuring cylinder 130 is reduced. When the elastic reset member 120 is contracted, the pressure of the elastic reset member 120 is increased, and the pressure transmitted to the measuring cylinder 130 is increased, thereby adjusting the pressure on the measuring cylinder 130. The measuring cylinder 130 is connected to the pressure cover 400. When the pressure cover 400 presses against the coffee powder, the pressure of the pressure cover 400 pressing against the coffee powder can also be adjusted.

[0048] 2) Compared with the impact-type constant-pressure coffee tamper in the prior art, the above-mentioned quantifiable pressure tamper 10 causes the elastic reset member 120 to move accordingly after the adjustment sleeve 110 rotates. When the elastic reset member 120 moves accordingly, it drives the movement of the push rod 300, so that the depth of coffee powder compaction by the tamper can be adjusted by rotation, and finally different depths of coffee powder compaction are achieved, and the best extraction style of different coffee powders can be achieved according to the depth of compaction.

[0049] The above embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be subject to the attached claims.
