[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0030] Example 1

[0031] The first embodiment of this utility model relates to a liquid storage container, such as... Figure 1 and Figure 8 As shown, the liquid storage container 3 includes, along its axial direction, a bottom 31 and a shell wall 32 arranged circumferentially around the bottom 31, with the shell wall 32 forming a liquid storage space 33 on the bottom 31. Meanwhile, the side of the shell wall 32 away from the bottom 31 is an open side 34.

[0032] Among them, combined Figure 2 As shown, the liquid storage container 3 is used to store the brewing components 1 of the pour-over coffee maker, or as... Figure 3 As shown, the liquid storage container 3 is also used to support the brewing assembly 1, so that the brewing assembly 1 protrudes from the opening side 34 and is away from the bottom 31.

[0033] As can be seen from the above, the liquid storage container 3 of the pour-over coffee maker not only stores the brewing component 1, making it convenient for users to carry the pour-over coffee maker, but also supports the brewing component 1, allowing the brewing component 1 to protrude from the opening side 34 of the liquid storage container 3 and away from the bottom 31 of the liquid storage container 3. This allows the liquid storage container 3 to receive the coffee liquid extracted from the brewing component 1, meeting the user's needs to enjoy pour-over coffee outdoors or in any other scenario.

[0034] Specifically, in some embodiments, such as Figure 3 , Figure 8 and Figure 9 As shown, the shell wall 32 of the liquid storage container 3 has an inner wall surface 321 that encloses the liquid storage space 33 and an outer wall surface 322 that is opposite to the inner wall surface 321, and is combined with Figure 8 As shown, the inner wall surface 321 is provided with a plurality of guide grooves 323 along its circumference. Each guide groove 323 extends from the opening side 34 toward the bottom 31, and a support portion 324 is formed between each pair of adjacent guide grooves 323 along the circumference of the inner wall surface 321. Wherein, as Figure 8 and Figure 4 As shown, each support portion 324 is used to support each support protrusion 141 on the brewing assembly 1, so that the brewing assembly 1 at least partially protrudes from the opening side 34 of the liquid storage container 3 and is away from the bottom 31, as shown. Figure 3 The state shown. Or, as... Figure 8 and Figure 4 As shown, each guide groove 323 slides into the support protrusion 141 on the brewing component 1, allowing the brewing component 1 to slide into the liquid storage space 33 of the liquid storage container 3, so that the brewing component 1 is housed within the liquid storage space 33. Figure 2 The state shown. For example, in some embodiments, the number of support portions 324 and guide grooves 323 of the liquid storage container 3 are the same as the number of support protrusions 141, and they correspond uniquely. Meanwhile, combined with... Figure 8 As shown, each support portion 324 is formed by a portion of the inner wall surface 321 of the shell wall 32 protruding away from the outer wall surface 322, such that the side of each support portion 324 relative to the opening side 34 is a support side 325 protruding from the inner wall surface 321, and each support side 325 is used to support each support protrusion 141 on the brewing assembly 1.

[0035] It is easy to see from this that when it is necessary to organize and store the brewing component 1, such as Figure 4 and Figure 8As shown, align the support protrusions 141 on the brewing assembly 1 with the corresponding guide grooves 323 on the liquid storage container 3. Therefore, the brewing assembly 1 can slide entirely into the liquid storage space 33 of the liquid storage container 3, allowing the liquid storage container 3 to store the brewing assembly 1. When it is necessary to use the brewing assembly 1 to brew coffee, as... Figure 8 and Figure 4 As shown, each support protrusion 141 on the brewing assembly 1 can be aligned with its corresponding unique support portion 324 on the liquid storage container 3, so that each support protrusion 141 can abut against each support side 325 of each support portion 324, thereby supporting the entire brewing assembly 1 at a preset position away from the bottom 31 of the liquid storage container 3. Figure 3 The state shown allows the storage space 33 formed between the brewing component 1 and the bottom 31 of the storage container 3 to receive the coffee liquid extracted from the brewing component 1. Furthermore, it should be noted that, in some embodiments, to allow the storage space 33 to hold more coffee liquid during coffee extraction, such as... Figure 8 As shown, the length of each support 324 can be extended so that the support side 325 of each support 324 can be closer to the opening side 34 of the liquid storage container 3. Thus, when the brewing component 1 is supported on each support side 325 of the support 324, there can be a larger vertical height between the brewing component 1 and the bottom 31 of the liquid storage container 3, so that the liquid storage space 33 can store more coffee liquid.

[0036] Furthermore, it is worth noting that, in order to enable the support portion 324 to provide stable support for the brewing component 1, in some embodiments, such as Figure 8 As shown, the support sides 325 of each support portion 324 are planar. Alternatively, as a preferred embodiment, in other embodiments, such as Figure 9 and Figure 10 As shown, each support side 325 includes: a plane 3251 for supporting the support protrusion 141; a first guide surface 3252 for guiding the support protrusion 141 of the brewing assembly 1 to the plane 3251 when the brewing assembly 1 rotates; and a second guide surface 3253 for guiding the support protrusion 141 of the brewing assembly 1 to the guide groove 323 when the brewing assembly 1 rotates. Wherein, as... Figure 9 and Figure 10 As shown, plane 3251 is disposed between the first guide surface 3252 and the second guide surface 3253, and the vertical distance from plane 3251 to the bottom 31 is greater than the vertical distances from the first guide surface 3252 and the second guide surface 3253 to the bottom 31, respectively. This allows plane 3251 to form a certain height difference with the first guide surface 3252 and the second guide surface 3253, and corresponding to this height difference, such as... Figure 9 and Figure 10As shown, a first limiting surface 3254 and a second limiting surface 3255 are respectively formed between the first guide surface 3252 and the second guide surface 3253 and the plane 3251. Therefore, when the plane 3251 abuts against the support protrusion 141 of the brewing assembly 1, the first limiting surface 3254 and the second limiting surface 3255 can respectively lock the support protrusion 141 around the axis of the brewing assembly 1, preventing the brewing assembly 1 from rotating around its own axis, thereby improving the stability of the brewing assembly when extracting coffee powder.

[0037] Additionally, it is worth mentioning that in some embodiments, such as Figure 9 and Figure 10 As shown, both the first guide surface 3252 and the second guide surface 3253 can be arc surfaces. With the help of these arc surfaces, when the brewing assembly 1 rotates forward, the supporting protrusions 141 can be accurately guided onto the respective planes 3251, thereby quickly positioning the brewing assembly 1 at a preset position away from the bottom 31 of the liquid storage container 3. Similarly, with the help of these arc surfaces, when the brewing assembly 1 rotates in the reverse direction, the supporting protrusions 141 can be accurately guided into the respective guide grooves 323, thereby quickly sliding the brewing assembly 1 into the liquid storage space 33 of the liquid storage container 3, allowing the liquid storage container 3 to store the brewing assembly. It should be noted that the above description of the first guide surface 3252 and the second guide surface 3253 using arc surfaces as an example is only applicable to other embodiments. In other embodiments, the first guide surface 3252 and the second guide surface 3253 can also be inclined surfaces, which can similarly guide the supporting protrusions 141 when the brewing assembly 1 rotates.

[0038] Example 2

[0039] Embodiment 2 of this utility model relates to a pour-over coffee device, such as... Figure 11 As shown, the pour-over coffee maker includes: a liquid storage container 3, a brewing assembly 1, and a top cover assembly 5 as described in Embodiment 1. The brewing assembly 1 holds coffee grounds and extracts coffee liquid from them. Furthermore, the brewing assembly 1 is housed within the liquid storage space 33 of the liquid storage container 3, or it can be supported at a predetermined position away from the bottom 31 of the liquid storage container 3, allowing the liquid storage container 3 to receive the coffee liquid extracted from the brewing assembly 1.

[0040] As can be seen from the above, the liquid storage container 3 of the pour-over coffee maker not only stores the brewing component 1, making it convenient for users to carry the pour-over coffee maker, but also supports the brewing component 1. This allows the brewing component 1 to be supported as a whole in a preset position away from its bottom 31 in the liquid storage container 3. At this time, the liquid storage container 3 can receive the coffee liquid extracted from the brewing component 1, meeting the user's needs to enjoy pour-over coffee outdoors or in any other scenario.

[0041] Specifically, in some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the brewing assembly 1 includes: a cup body 11, a water distribution component 13, a support frame 12, and a support structure 14. The cup body 11 has a top side 111 and a bottom side 112 at its two ends along its axial direction, and both the top side 111 and the bottom side 112 are open. Furthermore, in conjunction with... Figure 2 and Figure 3 As shown, the water distribution component 13 is disposed on the top side 111 of the cup body 11. The water distribution component 13 is used to receive the liquid medium injected from the outside and to divide the received liquid medium into several streams of fluid before discharging them into the cup body 11.

[0042] Additionally, in other embodiments, such as Figure 4 and Figure 7 As shown, the support frame 12 is disposed on the bottom side 112 of the cup body 11 along the axial direction of the cup body 11. This support frame 12 is used to support the filter paper (not shown in the figure) that can hold coffee powder, and is combined with Figure 2 , Figure 3 and Figure 6 As shown, the support frame 12 is provided with at least one liquid outlet hole 124 along the axial direction of the cup body 11, allowing the extracted coffee liquid to flow into the liquid storage space 33 of the liquid storage container 3 through each outlet hole 124. Finally, combined with Figure 4 and Figure 7 As shown, the support structure 14 is used for the cup body 11 to slide into the liquid storage space 33 of the liquid storage container 3, such as... Figure 2 The state shown, or the support structure 14 is also used to support the cup body 11 at a predetermined position away from the bottom 31 of the liquid storage container 3, such as... Figure 3 The state shown.

[0043] Furthermore, it is worth mentioning that in other embodiments, such as Figure 7 As shown, the water distribution component 13 is detachably mounted on the top side 111 of the cup body 11, allowing for convenient cleaning by the user and preventing dirt and grime buildup. Simultaneously, to enable a detachable connection between the water distribution component 13 and the cup body 11, as shown... Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the water distribution component 13 includes a perforated plate 131 and a side plate 132. The perforated plate 131 receives externally injected liquid media and divides the received liquid media into several streams before discharging them into the cup body 11. Figure 3 and Figure 6As shown, the perforated plate 131 has an upper surface 1311 and a lower surface 1312 opposite to the upper surface 1311. The upper surface 1311 is provided with a plurality of liquid inlets 1313, while the lower surface 1312 is provided with a plurality of liquid outlets 1314. The number of liquid inlets 1313 and the number of liquid outlets 1314 are the same and uniquely corresponded. Each liquid inlet 1313 is connected to a uniquely corresponding liquid outlet 1314, and the diameter of each liquid outlet 1314 is smaller than the diameter of each liquid inlet 1313. For example, in some embodiments, such as... Figure 3 , Figure 4 and Figure 5 As shown, the liquid inlets 1313 can be distributed in an array on the upper surface 1311 of the perforated plate 131, making the upper surface 1311 of the perforated plate 131 have a honeycomb structure. This ensures that the wall thickness between any two adjacent liquid inlets 1313 remains consistent in any direction, maximizing the number of liquid inlets 1313 on the perforated plate 131. Therefore, when the liquid medium for brewing coffee powder is poured onto the upper surface 1311 of the perforated plate 131, the liquid medium can flow evenly to each liquid inlet 1313. Simultaneously, as... Figure 2 and Figure 3 As shown, since the diameter of each outlet 1314 is smaller than the diameter of each inlet 1313, the flow rate of the liquid medium from each inlet 1313 to the unique outlet 1314 can be greatly reduced. This ensures that during the pouring of the liquid medium onto the upper surface 1311 of the porous plate 131, the liquid medium can continuously spread to the surrounding area of ​​the upper surface 1311 of the porous plate 131, and can quickly form a water film on the upper surface 1311 of the porous plate 131. This ensures that liquid medium can be discharged from each outlet 1314 onto the coffee powder layer supported by the filter paper, thereby achieving uniform extraction of the coffee powder layer by the liquid medium and avoiding under-extraction or over-extraction in local areas of the coffee powder layer.

[0044] Furthermore, in order to ensure that the water distribution component 13 can be stably supported on the top side 111 of the cup body 11, such as... Figure 5 and Figure 7 As shown, the side plate 132 of the water distribution component 13 is arranged circumferentially around the perforated plate 131, and the side plate 132 forms a water storage area 133 on the upper surface 211 of the perforated plate 21 to receive liquid media. Meanwhile, as... Figure 6 and Figure 7As shown, the side plate 132 away from the perforated plate 131 extends outward toward the water storage area 133 to form a bent portion 134. This bent portion 134 is used to abut against the top side 111 of the cup body 11, so that the side plate 132 of the water distributor 13 can be partially inserted into the cup body 11. This ensures that the water distributor 13 can be stably supported on the top side 111 of the cup body 11. Therefore, when the user pours the liquid medium for brewing coffee powder into the water distributor 13, the user can save the user from manually operating and controlling the water distributor 13. This not only makes it convenient for the user to brew coffee, but also ensures the uniformity of the extraction of coffee powder by the liquid medium, thereby ensuring the taste of the extracted coffee.

[0045] Additionally, it is worth noting that in some other embodiments, such as Figure 4 and Figure 7 As shown, the support frame 12 can be detachably connected to the cup body 11, and, combined with Figure 6 As shown, the support frame 12 includes a perforated plate 121 and a side wall 122. The perforated plate 121 is disposed on the bottom side 112 of the cup body 11, and the perforated plate 121 has a plurality of liquid outlet holes 124 distributed thereon. For example, the liquid outlet holes 124 can be distributed in an array. After the coffee powder layer is extracted by the liquid medium, the coffee liquid can be evenly discharged into the liquid storage container 3 through the liquid outlet holes 124, thereby further avoiding the phenomenon of over-extraction or under-extraction of the coffee powder layer. Furthermore, it is worth noting that in some embodiments, each liquid outlet hole 124 can be a regular hexagonal structure, making the mesh plate 121 have a honeycomb structure as a whole. This ensures that the wall thickness between any two adjacent liquid outlet holes 124 can be kept consistent in any direction, so that the number of liquid outlet holes 124 provided on the mesh plate 121 can reach the maximum. Of course, in other embodiments, the liquid outlet holes 124 can also be circular or square. However, in this embodiment, the shape of the liquid outlet holes 124 is not specifically limited.

[0046] In addition, such as Figure 4 , Figure 6 and Figure 7 As shown, the sidewall 122 is arranged circumferentially around the perforated plate 121, and the sidewall 122 is also detachably connected to the cup body 11. For example, as Figure 6As shown, the side wall 122 may be provided with an internal thread 123, while the cup body 11 has an external thread 116 that can be screwed into the internal thread 123 from the bottom side 112 to the top side 111, so that the cup body 11 and the side wall 122 can be threadedly connected, thereby allowing the support frame 12 to be detachably installed on the bottom side 112 of the cup body 11. It is easy to see that, with the detachable connection between the support frame 12 and the cup body 11, the support frame 12 can be removed from the cup body 11 after the coffee liquid extraction is completed. This not only makes it convenient for the user to remove the coffee grounds and filter paper after extraction, but also makes it easy for the user to clean the support frame 12, preventing dirt and grime from accumulating in the liquid outlet holes 124 of the support frame 12.

[0047] Furthermore, in order for the support frame 12 to support the cup body 11 at a predetermined position away from the bottom 31 of the liquid storage container 3, in other embodiments, such as Figure 6 As shown, the sidewall 122 has an inner side surface 1221 detachably connected to the cup body 11, and an outer side surface 1222 opposite to the inner side surface 1221, and is combined with Figure 4 As shown, the support structure 14 is disposed on the outer surface 1222 of the side wall 122. This support structure 14 is used for the cup body 11 to slide into the liquid storage space 33 of the liquid storage container 3, as shown. Figure 2 The state shown, or the support structure 14 is also used to support the cup body 11 at a predetermined position away from the bottom 31 of the liquid storage container 3, such as... Figure 3 The state shown. For example, in some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the support structure 14 includes a plurality of support protrusions 141, each support protrusion 141 being arranged circumferentially around the sidewall 122, and each support protrusion 141 protruding from the outer side surface 1222 of the sidewall 122 in a direction away from the inner side surface 1221. Furthermore, in some embodiments, when it is necessary to house the brewing assembly 1 within the liquid storage container 3, combined with... Figure 2 , Figure 4 and Figure 8 As shown, by means of the sliding engagement between each supporting protrusion 141 and each guide groove 323 of the liquid storage container 3, the entire brewing assembly 1 can be slid into the liquid storage space 33 of the liquid storage container 3, thus satisfying the storage container 3's requirement for housing the brewing assembly 1. When it is necessary to support the brewing assembly 1 at a preset position away from the bottom 31 of the liquid storage container 3, as shown... Figure 3 , Figure 4 and Figure 8 As shown, each support protrusion 141 can be supported on each support side 325 of the liquid storage container 3, so that the cup body 1 is separated from the bottom 31 of the liquid storage container 3, thereby allowing extraction of the coffee powder layer that is currently supported on the filter paper.

[0048] Furthermore, as can be seen from the above, since the pour-over coffee maker also includes a top cover assembly 5, and the top cover assembly 5 opens or closes the opening side 34 of the liquid storage container 3, after the brewing component 1 is stored in the liquid storage container 3, the top cover assembly 5 can close the opening side 34, which can further facilitate the user to carry the pour-over coffee maker, while also preventing the surface from being corroded by the external environment, thereby ensuring the cleanliness of the brewing component 1.

[0049] Specifically, in some embodiments, such as Figure 11 and Figure 14 As shown, the upper cover assembly 5 includes: a cover plate bracket 51 and a cover body 52. ​​Wherein, as... Figure 11 , Figure 12 and 15 As shown, the cover plate support 51 includes: an upper cover plate 511 for opening or closing the opening side 34 of the liquid storage container 3, an annular lower flange 512 disposed on the bottom side of the upper cover plate 511, and an annular upper flange 513 disposed on the top side of the upper cover plate 511. The annular lower flange 512 is inserted into the liquid storage space 33. The upper cover plate 511 can cover the opening side 34 of the liquid storage container 3, and the annular upper flange 513 can form a storage area 514 on the upper cover plate 511 for storing filter paper. Corresponding to the storage area 514, as shown... Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, the cover 52 is disposed on the annular upper flange 513 of the cover plate bracket 51, so that the cover 52 can be flipped relative to the cover plate bracket 51, so that the cover 52 can be used to open or close the storage area 514 of the cover plate bracket 51.

[0050] Furthermore, in order to allow the cover 52 to flip relative to the cover plate support 51, in some embodiments, such as Figure 14 As shown, the cover 52 and the annular upper flange 513 of the cover plate support 51 are rotatably connected by a pivot 53, allowing the cover 52 to be flipped relative to the cover plate support 51. Of course, as an alternative, in other embodiments, such as... Figure 17 As shown, the cover 52 and the annular upper flange 513 of the cover plate support 51 can also be connected by a flexible component 54, allowing the cover 52 to be flipped relative to the cover plate support 51. It is worth noting that the flexible component 54 can be made of rubber, silicone, fabric, etc., and the material of the flexible component 54 is not specifically limited in this embodiment. Furthermore, the cover 52 and the annular upper flange 513 can also be snap-fitted together. That is, when the cover 52 is in the storage area 514 of the closed cover plate support 51, the cover 52 can be snapped onto the annular upper flange 513, thereby preventing the cover 52 from being rotated by non-human external force, thus ensuring the reliability and stability of the cover 52 in the closed storage area 514.

[0051] Additionally, as a preferred embodiment, in other embodiments, such as Figure 11 and Figure 17 As shown, the upper cover assembly 5 further includes a lower cover plate 55, which is disposed on the bottom side 5111 of the upper cover plate 511. Therefore, when the upper cover plate 511 of the upper cover assembly 5 is closed on the opening side 34 of the liquid storage container 3, the lower cover plate 55 can abut against the bent portion 134 of the water distribution component 13, so that the lower cover plate 55 can have sufficient supporting force to support the upper cover plate 511, thereby effectively improving the strength of the upper cover assembly 5 when closed on the opening side 34 of the liquid storage container 3. In addition, in some other embodiments, such as Figure 11 and Figure 14 As shown, the upper cover assembly 5 also includes a sealing element 56, which can surround the outer surface of the annular lower flange 512, so that after the annular lower flange 512 is inserted into the liquid storage space 33, the sealing element 56 can achieve a seal between the annular lower flange 512 and the shell wall 32, thereby improving the sealing performance of the upper cover assembly 5 on the liquid storage container 3.

[0052] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
