Description

Technical Field

[0001] The present application relates to the field of coffee measurement, and in particular to a coffee powder scraper and a coffee powder detection kit. Background Art

[0002] In some production or competition scenarios, it is necessary to measure the color value of coffee powder. However, there are many variables that affect the color value of coffee powder. In order to improve the color value measurement accuracy of coffee powder, multiple portions of coffee powder are often taken to measure the color value separately, and the average value of the color value measurement results of each portion of coffee powder is taken as the color value of the coffee powder. However, factors such as the distance between the coffee powder and the colorimeter, the arrangement density of the coffee powder, etc. will affect the measurement of the color value of the coffee powder. Therefore, in the prior art, multiple measuring trays are filled with coffee powder, and the coffee powder in the measuring trays is compacted and flattened with a scraper, and then the color value of the coffee powder in each measuring tray is measured separately. However, this measurement method is relatively cumbersome and not user-friendly. Utility Model Content

[0042] Figure 1 FIG. 1 is a schematic structural diagram of an embodiment of the coffee powder scraper of the present application. Figure 1 As shown, the coffee powder scraper 10 comprises a detachable slider 11 and a base 12. The base is generally elongated and has at least two bearing slots 121 arranged in a row along the elongated direction (i.e., the length direction) of the elongated strip. The base 12 also includes a planar top surface 122, with the openings of the bearing slots 121 located on the top surface 122.

[0043] Two opposite side surfaces 123 of the base 12 are provided with rails 124 extending along the longitudinal direction, so that the slider can slide along the rails 124 over the openings of the row of loading grooves 121 to add coffee powder to the loading grooves 121 and to scrape the coffee powder in the loading grooves 121 flat. Specifically, the main body of the slider 11 is located on the top surface 122 of the base 12, and the slider includes a positioning structure ( Figure 1 (not shown), so that when the slider 11 slides back and forth along the length direction on the top surface 122 of the base, the moving direction of the slider 11 is limited by the movement of the positioning structure 111 along the track 124.

[0044] like Figure 2 and Figure 3 As shown, Figure 2 This is a structural diagram of an embodiment of a slider in the coffee powder scraper of the present application. Figure 3 yes Figure 2 The slider 11 is shown in a longitudinal cross-sectional view at the center. The slider 11 is provided with a powder filling channel 113 extending through the top and bottom surfaces 112 of the slider 11. Specifically, the powder filling channel 113 comprises a first opening 1131 at the bottom of the slider 11, a second opening 1132 at the top surface 112 of the slider, and an inner sidewall 1133 connecting the first and second openings 1131, 1132. The first opening 1131 abuts the top surface 122 of the base 12. The user introduces coffee powder into the powder filling channel 113 through the second opening 1132 on the top surface 112 of the slider 11. Because the first opening 1131 abuts the top surface 122 of the base 12 and the top surface 122 is flat, the coffee powder in the powder filling channel 113 is pushed along by the movement of the slider 11. When the slider 11 moves above each of the loading slots 121, the coffee powder in the powder filling channel falls from the first opening into the loading slot 121.

[0045] The width of the first opening 1131 in a direction perpendicular to the track 124 is greater than the width of the opening of each of the loading slots 121 in the direction perpendicular to the track 124. Thus, when the slider 11 passes over the loading slots 121, coffee powder can fall evenly into the loading slots 121 along the width of the loading slots 121. Optionally, the area of ​​the first opening 1131 can cover the opening of each of the loading slots 121, thereby accelerating the speed at which coffee powder is filled from the slider 11 into the loading slots 121.

[0046] At least one end of the base is provided with a locking structure for limiting the maximum moving distance of the slider 11. Figure 1As shown, the track 124 is specifically a bar-shaped groove, and the locking structure 125 is provided at one end of the track 124, specifically a stepped surface at one end of the track 124. Since the user can repeatedly fill the bearing groove 121 with coffee powder and scrape the coffee powder by moving the slider 11 back and forth, the locking structure 125 can prevent the user from sliding off the track 124 and falling off the base 12 when moving the slider 11 back and forth. Optionally, the first end of the track 124 is provided with the locking structure 125, and the second end is not provided with a locking structure, and the slider 11 is detached from the base by sliding to the outside of the second end of the track 124. Optionally, the base 12 is further provided with a handle 126 on the outside of the second end of the track 124, and the width of the handle 126 is smaller than the width of the base 12 to avoid blocking the slider 11 from sliding out of the base 12.

[0047] The volume of the powder filling channel 113 is at least 1.5 times the sum of the volumes of the at least two holding slots 121, for example, twice the sum of the volumes of the at least two holding slots 121. This allows the user to avoid multiple powder addition operations when repeatedly sliding the slider to fill and compact the coffee powder in the holding slots.

[0048] The periphery of the first opening 1131 includes two powder scraping walls 114 extending non-parallel to the track 124. These walls are located on opposite sides of the periphery and are used to scrape off any coffee powder in the at least two receiving slots 121 that extends beyond the openings of the receiving slots 121 as the slider 11 moves along the track 124. One of the two powder scraping walls 114 is also used to push the coffee powder within the powder loading slot 113 as the slider 11 moves in a single direction. The bottom of the slider 11 is recessed upwardly on either side of the two powder scraping walls 114, facing away from the first opening 1131. This ensures that only the two powder scraping walls 114 move against the top surface 122 of the base 12 and the openings of the at least two receiving slots 121 as the slider 11 moves along the track. This prevents coffee powder from becoming stuck between the bottom of the slider 11 and the top surface 122 of the base 12 as the slider 11 slides.

[0049] The thickness of the powder scraping wall 114 is smaller than the maximum particle size of the coffee powder. For example, the thickness of the two powder scraping walls 114 is less than 3 mm, such as 2 mm, 2.5 mm, 1 mm, etc. This can prevent coffee powder from getting stuck between the powder scraping wall 114 and the top surface 122 of the base 12 during the sliding of the slider 11.

[0050] Optionally, the angle between the powder scraping wall 114 and the top surface 122 of the base 12 is greater than 90 degrees or 90 degrees. Preferably, the powder scraping wall 114 is perpendicular to the top surface 122 of the base 12. This allows the two sides of the powder scraping wall 114 to apply uniform force to the coffee powder when the slider slides back and forth, making it easier to form highly consistent coffee powder in each loading groove.

[0051] Alternatively, in one example, the bottom width of the powder scraping wall 114 is smaller than the maximum particle size of the coffee powder. For example, the bottom width of the two powder scraping walls is less than 3 mm, such as 2 mm, 2.5 mm, 1 mm, etc. In addition, the two sides of the powder scraping wall are inclined, and the angles between them and the top surface of the base are both less than 90 degrees. In this way, when the user slides the slider back and forth, the powder scraping wall can also exert oblique downward pressure on the coffee powder, which helps to further compact the coffee powder in the supporting tank. Optionally, the two sides of the powder scraping wall have the same angle with the top surface of the base, so that the pressure on the coffee powder by the two sides of the powder scraping wall is consistent when the slider slides back and forth.

[0052] Optionally, the area of ​​the second opening 1132 is larger than the area of ​​the first opening 1131, which can increase the volume of the powder loading groove 113 of the slider 11 and facilitate the powder loading operation of the user. Optionally, at least part of the inner side wall of the powder loading groove 113 is inclined. In some examples, the inner side wall of the powder loading groove 113 of the slider 11 located above the two powder scraping walls 114 is inclined, and at least part of the inner side wall of the slider 11 located on both sides of the column of bearing grooves 121 is perpendicular to the top surface of the base 12. In this way, the overall width of the slider 11 can be close to the overall width of the base 12 while maximizing the volume of the powder loading groove, making it easier for the user to move the slider above the base 12; moreover, the inclined inner side wall 1133 can facilitate the falling of coffee powder into the first opening 1131. Optionally, on the inner side wall 1133 of the powder filling slot 113 , the inclined inner side wall 1133 and the inner side wall 1133 perpendicular to the top surface of the base 12 are connected by a smooth curved surface to facilitate users to clean the powder filling slot 113 .

[0053] In one example, the bottom of the slider 11 is provided with two concave stepped surfaces on either side of the two powder scraping walls 114, facing away from the first opening 1131. The first stepped surface 115, located away from the powder scraping wall 114, is designed to create as large a gap as possible between the bottom of the slider and the top surface of the base. This allows the user to use the outer surface of the powder scraping wall 114 facing in that direction to scrape coffee powder from the loading groove 121. Because the sidewall of the powder loading groove 113 above the powder scraping wall 114 is inclined, the second stepped surface 116, located near the powder scraping wall 114, can maintain a small thickness while creating a gap between the bottom of the slider and the top surface of the base, reducing processing difficulty.

[0054] Optionally, the bottom of the slider 11 further includes two support surfaces 117 connecting the two powder scraping walls 114, located on opposite sides of the first opening 1131 and on opposite sides of the row of bearing slots 121. The slider 11 is supported on the top surface 122 of the base 12 by the support surfaces 117 in addition to the powder scraping walls 114, thereby increasing the support area of ​​the slider on the top surface of the base and reducing the possibility of deformation of the slider 11 due to the small support area.

[0055] Alternatively, as Figure 1 and Figure 2 As shown, the slider 11 further includes two opposing side walls 118, each of which is connected to the top surface 112 of the slider 11. In one embodiment, the track 124 is a strip-shaped groove located on two opposing side surfaces of the base 12, and the locking structure 125 is a protrusion located on the inner side surface of the side wall of the slider 11, which is used to be locked in the track 124 when the slider 11 moves along the track 124. Alternatively, in one embodiment, the track is a protrusion located on two opposing side surfaces of the base, and the locking structure is a groove located on the inner side surface of the side wall of the slider, which is used to be locked on the protrusion when the slider moves along the track.

[0056] like Figure 4a As shown, Figure 4a This is a schematic diagram of the exploded structure of an embodiment of the base of the coffee powder scraper of the present application. Figure 4a In the illustrated embodiment, the base 12 includes a base 41 and a gasket 42 that are independent of each other. The base 41 and the gasket 42 are both generally in the shape of a long strip. The base 41 and the gasket 42 are stacked to form the base, and the top surface of the gasket 42 serves as the top surface 122 of the base 12.

[0057] In one instance, Figure 4b As shown, Figure 4bIt is a structural diagram of an embodiment of the base 41 and the detection device in the base of the coffee powder scraper of the present application. The at least two bearing grooves 121 are located on the base 41, and a protruding step 411 is provided around the opening periphery of each of the bearing grooves 121, which is used to limit the detection device 50 when the detection device 50 detects the coffee powder in the bearing groove 121. The detection device 50 can be used to detect the color value, particle size or other parameters of the coffee powder, which is not limited here. The gasket 42 is provided with at least two through holes 421 corresponding to the at least two bearing grooves 121. When the base 41 and the gasket 42 are stacked together, each through hole 421 is sleeved on the outside of the protruding step 411, so that the top surface of the protruding step 411 and the top surface 122 of the gasket 42 are located on the same plane. In this way, the base 12 formed by the base 41 and the gasket 42 can ensure that the top surface of the base is smooth to facilitate the sliding of the slider on the top surface of the base, while also providing a structure on the surface of the base 41 to limit the position of the detection equipment, so that the detection equipment can be aligned with the loading slots for testing the coffee powder. The base 41 and the gasket 42 are independent of each other. This makes it easy to remove the gasket 42 after the loading slots are filled with coffee powder and smoothed by the slider by stacking the base 41 and gasket 42 to test the coffee powder with the detection equipment, avoiding the coffee powder in the loading slots being moved during the removal process, which may affect the consistency of the coffee powder in each loading slot.

[0058] like Figures 5 to 7 As shown, Figure 5 This is a structural diagram of an embodiment of the top surface of the base and the bottom surface of the gasket in the coffee powder scraper of the present application. Figure 6 yes Figure 5 The schematic diagram of the structure of the top surface of the base of the coffee powder scraper shown in FIG. Figure 7 yes Figure 5 The bottom surface of the base gasket in the coffee powder scraper is shown in the figure. The base 41 includes a generally elongated bottom plate 412 and a support platform 413 protruding from the center of the bottom plate 412 along its length. The at least two bearing grooves 121 are disposed within the support platform 413, and the opening perimeters of the at least two bearing grooves 121 are located on the top surface of the support platform 413. The protruding step 411 protrudes from the top surface of the support platform 413.

[0059] A concave positioning groove 421 is provided in the middle of one side of the bottom surface of the gasket 42 along the length direction. When the base 41 and the gasket 42 are stacked, the support platform 413 is embedded in the positioning groove 421, and the top surface of the support platform 413 abuts against the bottom of the positioning groove 421, and the opening surface of the positioning groove 421 abuts against the chassis 412.

[0060] Alternatively, as Figures 6 to 8As shown, Figure 8 yes Figure 5 The schematic diagram of the cross-sectional structure of the base in the coffee powder scraper shown is perpendicular to the length direction. The top surface 4131 of the support platform 413 is also provided with a concave step 4132 extending along the length direction at both side edges, so that a gap 71 is formed between the top surface 4131 of the support platform 413 and the bottom of the positioning groove 421. The opening surface 4211 of the positioning groove 421 is also provided with a concave step 4212 extending along the length direction, so that a gap 72 is formed between the opening surface 4211 of the positioning groove 421 and the chassis. The design of these gaps can make it possible for any coffee powder to escape from the bottom surface of the slider when the slider pushes the coffee powder to fall into the gap of the base, thereby avoiding the base and gasket of the base from being unable to close due to the coffee powder being clamped, and also making it convenient for users to clean. Optionally, as Figure 5 As shown, the opening surface 4211 of the positioning groove 421 is provided with a plurality of disconnected concave steps 4212, so that the area of ​​the opening surface 4211 of the positioning groove 421 can be increased while retaining the gap, so as to increase the contact area between the opening surface 4211 of the positioning groove 421 and the chassis 412 of the base 41, increase the support degree of the base 41 for the gasket 42, and reduce the possibility of structural deformation.

[0061] In some examples, the present application provides a coffee powder detection kit, comprising any one of the coffee powder scrapers and detection equipment described above. The detection equipment has a detection port, the opening size and shape of which matches the opening size and shape of the carrying slot of the coffee powder scraper. The detection equipment is used to detect at least one attribute parameter of the coffee powder in the carrying slot when the detection port covers the carrying slot. The attribute parameter may include at least one parameter such as the color value, particle size, and roasting degree of the coffee powder. Optionally, as Figure 4b As shown, a limiting structure is provided on the inner wall of the detection port for cooperating with the raised step at the periphery of the opening of the bearing slot of the base of the coffee powder scraper. When the detection device is covered above one of the bearing slots on the base, the cooperation between the limiting structure and the raised step prevents the detection device from moving horizontally. For example, an annular groove is provided on the inner wall of the detection port. After the user uses the coffee powder scraper to fill and level the coffee powder in each bearing slot, the user removes the gasket from the base and covers the detection device on one of the bearing slots on the base. The raised step on the bearing slot is embedded in the annular groove of the detection device. After the user has completed the detection of the coffee powder in the bearing slot by operating the detection device, the user can move the detection device to cover the second bearing slot and repeat the detection operation. After obtaining the detection results of the property parameters of the coffee powder in each bearing slot, the detection device can average the detection results to obtain the final detection result.

[0062] The embodiments of the present application have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to the technology in the market, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
