DETAILED DESCRIPTION

[0055] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0056] Reference is made to the drawings in the embodiments of the present application Figure 1 and the drawings in the embodiments of the present application Figure 2 ​The utility model discloses a coffee powder presser, including first cylinder body 1, second cylinder body 2, adjusting mechanism 3, first cylinder body 1 vertical arrangement is equipped with the first spring 4 in first cylinder body 1's inside and has the slide connection with the rammer 5, and the bottom of first spring 4 abuts the top of rammer 5, second cylinder body 2 is sleeved in the outside of first cylinder body 1 and is connected with first cylinder body 1 directional sliding, and the bottom of second cylinder body 2 is connected with the powder hammer 6, and first cylinder body 1 and second cylinder body 2 relatively move, and first spring 4 has the first state of the pressure accumulation and the second state of the pressure release, when first spring 4 is in the first state, the maximum pressure that first cylinder body 1 and second cylinder body 2 generate in the relative movement process is constant, when first spring 4 is in the second state, rammer 5 can impact powder hammer 6, adjusting mechanism 3 is set up on first cylinder body 1, and the initial length of first spring 4 can be adjusted, to change the initial pressure of first spring 4, to change the impact degree of rammer 5 and the powder pressing degree of powder hammer 6.

[0057] In actual use, the initial length and initial pressure of the first spring 4 are adjusted to predetermined values by the adjusting mechanism 3, and then the first cylinder body 1 and the second cylinder body 2 are relatively moved, so that the first spring 4 is in the first state of accumulating pressure. At this time, the rammer 5 is in a static state relative to the second cylinder body 2, and the powder hammer 6 will flatten the coffee powder in the coffee handle with the relative movement of the first cylinder body 1 and the second cylinder body 2. Continue to relatively move the first cylinder body 1 and the second cylinder body 2, when the first spring 4 is in the second state of releasing pressure, the rammer 5 will enter the motion state from the static state and impact the powder hammer 6, and the last stamping of the coffee powder in the coffee handle is performed, and the user is reminded that the pressure of the stamped coffee powder has reached the predetermined value. Since the final powder pressing degree of the powder hammer 6 is determined by the impact force of the rammer 5, and the impact force of the rammer 5 is composed of the pressure accumulated by the first spring 4 in the first state and the initial pressure of the first spring 4, and the maximum pressure accumulated by the first spring 4 in the first state is constant, and the initial pressure of the first spring 4 can be easily adjusted by the adjusting mechanism 3 located on the first cylinder body 1, therefore, without disassembling the entire coffee powder presser, or replacing different types of springs or other elastic members, the initial pressure of the first spring 4 can be conveniently and quickly adjusted, so as to change the impact force of the rammer 5 and the powder pressing degree of the powder hammer 6, which is simple to operate and saves time and effort. In general, by using the coffee powder presser, the powder pressing degree of the powder hammer 6 can be conveniently and quickly adjusted.

[0058] It should be noted that the above-mentioned "first cylinder body 1 and second cylinder body 2 directional sliding connection" means that the first cylinder body and the second cylinder body can only relatively move in one direction, and cannot relatively rotate. In addition, there are various ways of relative movement. For example, under the premise that the second cylinder body 2 remains stationary, if the first spring 4 is in the first state, the first cylinder body 1 needs to be pressed down, so that the first spring 4 is constantly shortened, thereby accumulating pressure.

[0059] It should be noted that the above-mentioned "initial length of the first spring 4" is not the length of the first spring 4 in the natural state without force, but the length of the first spring 4 when it is not working in the coffee powder presser. At this time, the first spring 4 may be under force or not.

[0060] It should be noted that the above-mentioned "initial pressure of the first spring 4" refers to the pressure accumulated by the first spring 4 when it is not working in the coffee powder presser. Taking the length of the first spring 4 in the natural state without force as the natural length, when the natural length is equal to the initial length, the initial pressure of the first spring 4 is zero, and when the natural length is not equal to the initial length, the initial pressure of the first spring 4 is not zero. Since the first spring 4 in the present application is obviously a pressure spring, the initial length can only be less than or equal to the natural length, and when the initial length is less than the natural length, the initial pressure of the first spring 4 is greater than zero.

[0061] It should be noted that the first spring 4 conforms to Hooke's law, that is, the stress and strain in the material are linearly related after the solid material is under force. Since the first spring 4 is in the first state, the maximum pressure generated during the relative movement of the first cylinder 1 and the second cylinder 2 is constant, therefore, the maximum deformation of the first spring 4 during the relative movement of the first cylinder 1 and the second cylinder 2 is fixed, and the maximum deformation does not include the deformation of the first spring 4 when it is not working in the coffee powder presser.

[0062] Based on the above, the maximum pressure generated during the relative movement of the first cylinder 1 and the second cylinder 2 is called the working pressure of the first spring 4, and the initial pressure of the first spring 4 + the working pressure of the first spring 4 = the impact pressure of the hammer 5. Since the working pressure of the first spring 4 is obviously constant, the impact pressure of the hammer 5, that is, the maximum powder pressing force of the powder hammer 6, can be changed by changing the initial pressure of the first spring 4.

[0063] It should be noted that the material, shape, size, color and other parameters of each component in the present application are not limited, and can be flexibly selected according to actual needs, such as material, single material or mixed material such as metal, plastic, solid wood, etc. can be selected; such as shape, various geometric shapes with aesthetic sense can be designed on the premise of not affecting its own function; such as size, it can be made according to the actual size of the coffee handle; such as color, different components can be designed in different colors, which is convenient for distinguishing and quickly assembling, and also more beautiful.

[0064] Further, the type of the powder hammer 6 is not limited in the present application, and different types of the powder hammer 6 can be set in material, shape, weight, diameter, thickness, etc. to make the extracted coffee flavor as much as possible to meet the needs of the drinker, for example, different patterns 61 can be set at the bottom of different types of the powder hammer 6 for extracting different coffee flavors; refer to the following drawings Figure 13 In the embodiment, the pattern 61 is set as a groove or protrusion structure composed of a plurality of concentric circles.

[0065] Refer to the following drawings Figure 4 and the following drawings Figure 5 In order to enable the first cylinder 1 and the second cylinder 2 to slide in a direction, the following design is made in the embodiment, specifically, the outer wall of the first cylinder 1 is provided with at least one first guide 101, and the inner wall of the second cylinder 2 is provided with a first guide groove 201 corresponding to the first guide 101, and the first guide groove 201 is vertically arranged.

[0066] Through the design of the above structure, the first cylinder 1 and the second cylinder 2 can slide in the vertical direction under the cooperation of the first guide 101 and the first guide groove 201, and the mutual rotation of the first cylinder 1 and the second cylinder 2 can be prevented.

[0067] Refer to the following drawings Figure 3 - the following drawings Figure 5 In order to enable the first spring 4 to have a first state of accumulating pressure and a second state of releasing pressure, the following design is made in the embodiment, specifically, it further includes a first sliding groove 7, a second sliding groove 8, and a sliding block 9, the first sliding groove 7 is at least one and is arranged on the side of the first cylinder 1, the first sliding groove 7 is vertically arranged, the top of the first sliding groove 7 is provided with an upper slope 71, the bottom of the first sliding groove 7 is provided with a lower slope 72, and the bottoms of the upper slope 71 and the lower slope 72 are located on the same side of the first sliding groove 7; the second sliding groove 8 is consistent in number with the first sliding groove 7, the second sliding groove 8 is arranged on the second cylinder 2 and corresponds to the first sliding groove 7 one by one, the second sliding groove 8 is vertically arranged, and the top of the second sliding groove 8 is provided with a horizontally arranged clamping groove 81; the sliding block 9 is consistent in number with the first sliding groove 7, the sliding block 9 is arranged on the hammer 5 and corresponds to the first sliding groove 7 one by one, and the sliding block 9 simultaneously passes through the first sliding groove 7 and the second sliding groove 8; in the natural state, the sliding block 9 passes through the bottom of the lower slope 72 and the clamping groove 81.

[0068] Through the design of the above structure, the first cylinder body 1 and the second cylinder body 2 are relatively moved, so that the upper slope 71 gradually approaches the sliding block 9, at this time, the first spring 4 is in the first state and can accumulate pressure; when the bottom of the upper slope 71 abuts against the sliding block 9, the first cylinder body 1 is continuously moved, the top of the upper slope 71 gradually approaches the sliding block 9, and since the upper slope 71 is inclined, the sliding block 9 is driven to deviate to the vertical part of the second sliding groove 8, until the sliding block 9 moves to the vertical part of the second sliding groove 8, the first spring 4 changes from the first state to the second state and can release pressure, so that the rammer 5 impacts the powder hammer 6.

[0069] It should be noted that the number and arrangement of the first sliding groove 7 are not limited in the present application, and can be designed flexibly according to actual needs, for example, when the first sliding groove 7 has at least two, it can be arranged in an annular array around the first cylinder body 1, and the second sliding groove 8, the sliding block 9 and other structures or components are correspondingly arranged, so that the components are evenly stressed and are not easily deviated during relative movement, and the movement is more smooth.

[0070] Referring to the accompanying drawings Figure 3 It should be noted that in the natural state, under the elastic force of the first spring 4 on the rammer 5, the sliding block 9 is located at the bottom of the lower slope 72; in addition, since the sliding block 9 can be deflected in the horizontal direction, the size of the sliding block 9 should be smaller than the width of the first sliding groove 7, so as to leave enough space for the movement of the sliding block 9 in the horizontal direction; further, the size of the sliding block 9 can be substantially equal to the width of the vertical part of the second sliding groove 8, so as to guide the movement of the sliding block 9 on the second cylinder body 2.

[0071] Referring to the accompanying drawings Figure 6 Further, a sleeve 14 corresponding to the second sliding groove 8 can be arranged on the side surface of the second cylinder body 2, so as to block the movement path of the sliding block 9, which not only prevents the sliding block 9 from hooking or scratching other objects during movement, but also makes the surface of the entire coffee powder crusher smoother, more flat and more beautiful.

[0072] Referring to the accompanying drawings Figure 5 and the accompanying drawings Figure 6 Further, in order to facilitate the processing of the second cylinder body 2, the first guide groove 201 and the second sliding groove 8 are arranged coincidentally in the embodiment.

[0073] Referring to the accompanying drawings Figure 2 , the accompanying drawings Figure 3 and the accompanying drawings Figure 11 Further, in the embodiment, the following design is made, specifically, the sliding block 9 is designed in a cylindrical shape, and the axis of the sliding block 9 is located in the horizontal plane.

[0074] Through the design of the above structure, the friction between the sliding block 9 and the first cylinder 1 can be effectively reduced, and the friction between the sliding block 9 and the second cylinder 2 can also be effectively reduced, so that the sliding block 9 is facilitated to move in the first sliding groove 7 and the second sliding groove 8. In addition, the outer surface of the sliding block 9 is more rounded, which can also effectively reduce the damage of the sliding block 9 to the first cylinder 1, the second cylinder 2 and itself during movement.

[0075] Referring to the accompanying drawings Figure 1 and the accompanying drawings Figure 2 , the structure capable of adjusting the length and pressure of the first spring 4 is various, and one of them is introduced in the embodiment. Specifically, the adjusting mechanism 3 comprises a plugging assembly 31 and an adjusting assembly 32. The plugging assembly 31 is arranged at the top of the first cylinder 1 and is used to plug the opening at the top of the first cylinder 1. The adjusting assembly 32 is arranged between the first cylinder 1 and the plugging assembly 31, the bottom of the adjusting assembly 32 abuts against the first spring 4, and the bottom of the adjusting assembly 32 is liftable.

[0076] Through the design of the above structure, the first spring 4 is limited between the plugging assembly 31 and the hammer 5, so as to prevent the first spring 4 from being separated from the first cylinder 1. Since the bottom of the adjusting assembly 32 abuts against the first spring 4 and the bottom of the adjusting assembly 32 is liftable, the length of the first spring 4 can be compressed and shortened or automatically reset by moving the bottom of the adjusting assembly 32, so as to achieve the purpose of adjusting the initial length and initial pressure of the first spring 4.

[0077] Referring to the accompanying drawings Figure 1 , the accompanying drawings Figure 2 and the accompanying drawings Figure 8 - the accompanying drawings Figure 10 , the structure capable of achieving the plugging effect is various, and one of them is introduced in the embodiment. Specifically, the plugging assembly 31 comprises a connecting piece 311, a rod body 312 and a pressing handle 313. The connecting piece 311 is connected to the top of the first cylinder 1, and a vertical guide hole 3111 is arranged on the connecting piece 311. The rod body 312 is vertically arranged and is fixedly connected at the bottom to the connecting piece 311. The rod body 312 is cylindrically arranged and is provided with a threaded segment 3121 at the upper portion. The pressing handle 313 is threadedly connected to the upper portion of the rod body 312.

[0078] Through the design of the above structure, the opening at the top of the first cylinder 1 can be plugged by the connecting piece 311, and the pressing handle 313 is threadedly connected to the upper portion of the rod body 312. Since the pressing handle 313 is obviously detachable, the pressing handle 313 can be detached for cleaning, maintenance or replacement.
