Description

TECHNICAL FIELD

[0001] The utility model relates to the field of brewing device, especially to a brewing cup. BACKGROUND

[0002] The love pressure and the method pressure kettle are two kinds of brewing devices for quickly brewing coffee powder, tea powder and the like to form coffee, tea and the like in the related art. Among them, the love pressure is composed of a filter cartridge, a piston pressure rod, a filter cover and filter paper, and the operation mode for brewing coffee by using the love pressure is as follows: the filter paper is placed on the bottom surface of the concave cavity of the filter cover, the filter cover with the filter paper is assembled at the bottom of the filter cartridge to form a filter assembly, then the filter assembly is vertically placed on the top of an additional cup with the filter cover downward, coffee powder and water are respectively added into the filter cartridge, then stirring is performed, the piston pressure rod is inserted into the filter cartridge, the piston pressure rod is pressed downward to make the liquid in the filter cartridge flow into the cup below the filter cover through the filter paper and the filter hole of the filter cover, and the residue is left above the filter paper. When the piston pressure rod is pressed to the position, the brewing of coffee is completed. The method pressure kettle is composed of a kettle body, a top cover, a metal filter disc and a pressure rod, and the operation mode for brewing coffee by using the method pressure kettle is as follows: coffee powder and hot water are sequentially added into the kettle body, a module composed of the top cover, the metal filter disc and the pressure rod is assembled on the kettle body to make the top cover cover the top opening of the kettle body, then the kettle body is left for several minutes, and then the pressure rod is pressed downward to make the pressure rod move downward through the through hole of the top cover and push the metal filter disc to descend, so that the residue in the kettle body is pressed, and the liquid penetrates into the space above the metal filter disc through the filter hole of the metal filter disc. When the pressure rod is pressed to the position, the brewing of coffee is completed, and the brewed coffee can be poured into an additional cup for drinking.

[0003] However, the love pressure and the method pressure kettle have deficiencies in specific application, which are as follows:

[0004] (1) Deficiencies of the love pressure: (1.1) Since the residue generated by the love pressure filtration is compressed above the filter paper, the residue is easy to block the filtration channel, which affects the downward penetration of the liquid into the cup, and requires a large force to press the piston pressure rod, which affects the user experience. (1.2) Since the love pressure needs to use an additional cup to complete the brewing of coffee, a solid and compatible cup needs to be prepared in advance every time the coffee is brewed, which is very inconvenient to use. (1.3) Since the bottom of the love pressure is not a sealed structure, the love pressure cannot form a sealed space, so it can only be used as a brewing device, but cannot be used as a liquid storage container for reference liquid such as water, and the function is relatively single. (1.4) Since the top of the filter cartridge for mixing coffee powder and water of the love pressure is in an open structure, an additional stirring piece needs to be used to stir the coffee powder and water before the piston pressure rod is inserted into the filter cartridge, so as to achieve the effect of sufficient mixing of the coffee powder and water.

[0005] (2) The disadvantages of the French press kettle are as follows: (2.1) After the coffee is brewed by using the French press kettle, the metal filter disc and the kettle body are all left with residues, and the residues are difficult to clean; (2.2) Since the French press kettle uses a metal filter disc as a filtering component, the filtering precision is relatively low, the filtering effect is poor, and the coffee prepared has a large powder taste, which affects the taste of the coffee; (2.3) The top of the pressing rod of the French press kettle is a small ball, and the user pushes the pressing rod downward by pressing the small ball with the hand, the acting area of the small ball is small, the operation comfort is poor, and the user is inconvenient to use; (2.4) The brewed coffee needs to be poured from the kettle body to an additional cup for drinking, which is inconvenient for the user to use; (2.5) Since a through hole needs to be arranged in the middle of the top cover of the French press kettle for the pressing rod to pass through and move up and down, the French press kettle cannot form a sealed space, and it cannot be inverted when loaded with liquid, so it cannot be used as a liquid storage container for drinking liquid such as water, and the function is relatively single; (2.6) Since the top cover of the French press kettle covers the top opening of the kettle body, and is only pressed on the kettle body, and does not form a sealed connection with the kettle body, the French press kettle can only stir the coffee powder and water by means of an additional stirring piece before covering the top cover on the kettle body, so as to achieve the effect of fully mixing the coffee powder and water.

The filter paper 202 is detachably connected with the filter 201, i.e. the filter paper 202 can be connected with the filter 201 and can be detached from the filter 201 to achieve the separation from the filter 201. The filter paper 202 is used to move from the first opening 102 towards the closed portion 102 under the pushing of the filter 201 and to cover the end of the filter 201 towards the closed portion 102, and to filter the mixed liquid in the accommodating cavity 103 formed by the mixing of the brewing powder and the liquid solvent to separate the residue and the liquid in the mixed liquid, i.e. the filter paper 202 is used to cover the bottom of the filter 201 and to filter the mixed liquid in the accommodating cavity 103. In this embodiment, the filter paper 202 is used to filter and separate the residue and the liquid in the mixed liquid, which can greatly improve the filtering precision compared with the metal filter screen, thereby facilitating the reduction of the powder feeling of the liquid formed by the brewing of the brewing cup 10, and by replacing the filter paper 202 with different filtering precision, the diversified brewing and extraction needs of the user can be met. When the brewing cup 10 is used to brew coffee, compared with the metal filter screen, the filter paper 202 can more efficiently filter the coffee residue, not only can significantly optimize the taste of the coffee, but also can reduce the powder feeling, so that the filtered coffee almost does not contain the powder feeling.

[0092] As an implementation, the pushing member 320 can be detachably connected to the filter 201, that is, the pushing member 320 can be connected to the filter 201 and can be detached from the filter 201 to achieve the separation from the filter 201. And the pushing member 320 is used to push the filter 201 and the filter paper 202 to move along the first opening 101 towards the closed part 102 under the action of external force, so that the filter 201 and the filter paper 202 push the residues in the mixed liquid in the containing cavity 103 towards the closed part 102, and the liquid in the mixed liquid passes through the filter paper 202 into the space between the filter paper 202 and the first opening 101. In specific applications, when it is needed to brew the brewing powder by using the brewing cup 10, after the brewing powder and the liquid solvent are added into the cup body 100 and are mixed sufficiently, the filter paper 202 is first overlapped on the top of the cup body 100, then the filter 201 is erected on the filter paper 202, and then the pushing member 320 is attached to the filter part 200, and then the pushing member 320 is pressed downward to drive the filter 201 and the filter paper 202 to move towards the cup body 100, so that the filter paper 202 pushes the residues in the mixed liquid in the cup body 100 towards the bottom of the cup body 100. In the present embodiment, the residues in the mixed liquid in the cup body 100 are pushed towards the closed part 102 by the pushing member 320 pushing the filter 201 and the filter paper 202 to move, and the liquid in the mixed liquid passes through the filter paper 202 into the space between the filter paper 202 and the first opening 101, so that the residues are prevented from contacting the pushing member 320 and the filter 201 by the isolation of the filter paper 202, thereby effectively reducing the cleaning difficulty of the brewing cup 10 after use. Of course, in specific applications, the setting mode of the pushing member 320 and the filter 201 is not limited to this, for example, as an alternative implementation, the pushing member 320 and the filter 201 can also be set in a telescopic connection mode or other movable connection mode, and the pushing member 320 can be telescoped to different states to achieve the storage and pushable downward pressing of the pushing member 320.

[0093] With reference to Figures 3 to 6As shown, as an embodiment, before the pushing member 320 pushes the filter 201 and the filter paper 202 to move towards the closed portion 102, the filter paper 202 is overlapped on the edge of the first opening 101, the filter 201 is vertically placed on the filter paper 202, and there is a spacing between the bottom of the filter 201 towards the closed portion 102 and the filter paper 202, that is, after the filter paper 202 is overlapped on the cup body 100 and the filter 201 is vertically placed on the filter paper 202, and before the pushing member 320 is pressed to move downwards, the bottom of the filter 201 does not directly contact the filter paper 202, but there is a spacing, so that there is a certain foldable space between the filter paper 202 and the bottom of the filter 201. In the process of the pushing member 320 pushing the filter 201 and the filter paper 202 to move towards the closed portion 102, the filter paper 202 is gradually compressed and deformed to fold, so that a part of the filter paper 202 is folded and covered on another part of the filter paper 202, until the filter paper 202 is compressed and folded to contact the bottom of the filter 201. After the pushing member 320 pushes the filter 201 and the filter paper 202 to move towards the closed portion 102, the part of the filter paper 202 between the bottom of the filter 201 and the closed portion 102 is partially stacked and abuts on the bottom of the filter 201, that is, after the filter paper 202 is compressed and folded, at least two layers of stacked structure are formed. The at least two layers of stacked structure formed by the compression and folding of the filter paper 202 constitute a pleated structure 2026 (refer to Figure 6The irregular fold structure 2026 is an irregular fold structure formed by the compression and folding of the filter paper 202 during the pressing process, and a three-dimensional channel can be formed through the irregular fold structure 2026. In this way, not only is the effective filtering area of the filter paper 202 increased, but also a multi-stage filtering mechanism is achieved, that is, large-particle residues are intercepted by the gaps of the fold structure 2026, and small-particle residues are filtered through the micropores of the filter paper 202 itself. In this way, the filtering precision and efficiency can be further improved, and the force required to press the pressing member 320 can be reduced. The undulating structure of the fold structure 2026 can force the liquid to flow in multiple directions when flowing through the filter paper 202, breaking the traditional laminar flow mode of vertical infiltration in the filter paper, enhancing the contact efficiency of the liquid with the surface of the filter paper 202, and reducing the static accumulation of residues on the surface of the filter paper 202. In addition, microscopic observation shows that after brewing is completed using the brewing cup 10 of the present embodiment, residues are mainly distributed in the edge gaps of the fold structure 2026, and the filtering micropores of the filter paper 202 remain unblocked. The reason is mainly that the edge gaps of the fold structure 2026 can form a local low-pressure area, which can induce residues to be preferentially adsorbed on the backflow surface of the fold structure 2026 (i.e., the edge gaps), rather than directly blocking the micropores of the filter paper 202. Moreover, the three-dimensional channel formed by the fold structure 2026 allows the liquid to have a flushing effect on the adsorbed residues during the flow process, preventing excessive accumulation of particle residues. In the present embodiment, by arranging the filter paper 202 to form a fold structure 2026 that can be compressed and folded during the pressing process, an irregular three-dimensional channel can be formed through the fold structure 2026, thereby optimizing the fluid dynamics and optimizing the distribution pattern of particle residues. This significantly reduces the blocking of the micropores of the filter paper 202, and improves the uniformity and efficiency of the extraction of the brewing powder. This design breaks through the two-dimensional filtering mode of traditional filter paper and provides a new solution for the performance optimization of filter paper 202.

[0094] As an embodiment, the part of the filter paper 202 between the bottom of the filter 201 and the closed portion 102 is partially laminated to form a fold structure 2026. The height of the three-dimensional channel formed at the bottom of the filter paper 202 is 0.2mm-1mm, and the three-dimensional channel is irregular. The formation of the three-dimensional channel significantly optimizes the fluid dynamics and the distribution pattern of particle residues during the filtering process, which helps to better solve the problem of blocking of the micropores of the traditional filter paper 202.

[0095] As an embodiment, the filter paper 202 is a disposable product, and one filter paper 202 is discarded after completing one brewing operation. The next time, a new filter paper 202 is used for filtering.

[0096] Reference Figure 4 ,Figure 5 and Figure 18 As shown in FIG. 2, as an embodiment, the filter 201 comprises a cylinder 210 and a filter head 220. The filter head 220 is assembled or integrally formed on the end of the cylinder 210 facing the closed part 102, i.e. the filter head 220 is arranged at the bottom end of the cylinder 210, and the filter head 220 and the cylinder 210 can be two separate parts assembled and connected, or can be an integrally formed part. The filter paper 202 is detachably connected to the filter head 220, and when the filter 201 pushes the filter paper 202 to move towards the closed part 102, the filter paper 202 covers the outside of the filter head 220. The pushing member 320 is detachably connected to the cylinder 210, and the pushing member 320 is used to push the cylinder 210 to drive the filter head 220 and the filter paper 202 to move along the first opening 101 towards the closed part 102 under the action of external force. The filter head 220 cooperates with the filter paper 202 to form the filter part of the filter assembly 200. The filter assembly 200 is detachably and movably arranged in the accommodating cavity 103 with the filter part facing the closed part 102 from the first opening 101. The cylinder 210 is an axially hollow part, i.e. the cylinder 210 is axially through and forms an axial through hole 214. The cup body 100 forms a similar outer cup structure, and the cylinder 210 forms a similar inner cup structure. The top of the filter assembly 200 adopts the cylinder 210, which is beneficial to realize the nested cooperation with the pushing member 320, beneficial to the assembly cooperation with the filter head 220, and further beneficial to reduce the weight and material cost of the filter assembly 200. In this embodiment, the filter head 220 cooperates with the filter paper 202 to form the filter part, so that the filter area can be increased by using the filter head 220, thereby facilitating to reduce the resistance of the filter assembly 200 pushed to move towards the closed part 102, and further facilitating to reduce the pushing force required by the user to push the top cover assembly 300 to move towards the closed part 102 during the brewing process, and facilitating to reduce the difficulty of the user to push the top cover assembly 300 to move towards the closed part 102 during the brewing process, and improving the convenience of the user to use the brewing cup 10.

[0097] As an embodiment, the filter head 220 is detachably connected with the barrel 210, i.e. the filter head 220 can be connected with the bottom end of the barrel 210, and can also be removed from the bottom end of the barrel 210 to achieve the separation with the barrel 210. In this embodiment, the filter head 220 and the barrel 210 are two parts manufactured separately, and the filter head 220 and the barrel 210 are detachably connected, so that the filter head 220 is convenient for cleaning, maintenance and replacement in the later stage. Of course, as an alternative embodiment, the filter head 220 and the barrel 210 can also be one part manufactured integrally in specific applications. Alternatively, as another alternative embodiment, the filter head 220 and the barrel 210 can also be two parts manufactured separately and connected in a non-detachable manner, i.e. after the two parts are assembled together, the two parts cannot be detached without damaging the parts.

[0098] As an embodiment, the barrel 210 and the filter head 220 are both rigid parts, and the filter paper 202 is a flexible part. When the pushing member 320 pushes the barrel 210 to drive the filter head 220 and the filter paper 202 to move downward, the barrel 210 and the filter head 220 will not be deformed, and the filter paper 202 will be deformed by being squeezed and folded.

[0099] Referring to FIGS. 1, 2 and 3, Figure 4 and Figure 5 As an embodiment, the brewing cup 10 further comprises a first sealing ring 400, which is sleeved outside the filter head 220 to seal the cooperation gap between the filter head 220 and the inner side wall of the accommodating cavity 103 when the filter member 200 is inserted into the accommodating cavity 103, i.e. the first sealing ring 400 is sealingly cooperated with the inner side wall of the accommodating cavity 103. The first sealing ring 400 is arranged to seal the cooperation gap between the outer side wall of the filter member 200 and the inner side wall of the cup body 100 when the filter member 200 is inserted into the cup body 100, so as to prevent the residues and liquid from entering between the outer side wall of the filter member 200 and the inner side wall of the cup body 100 from below, thereby further reducing the cleaning difficulty of the brewing cup 10 after use.

[0100] Referring to FIGS. 1, 2 and 3, Figures 3 to 8As shown, as an implementation form, the filter paper 202 is formed with a first concave cavity 2021 having a first cavity opening 2022 arranged towards the first opening 101 and a cavity bottom wall 2023 arranged opposite to the first cavity opening 2022. The filter paper 202 is wrapped outside the filter head 220 with the first cavity opening 2022 towards the first opening 101. The first concave cavity 2021 further has a cavity side wall 2024 extending from a circumferential edge of the cavity bottom wall 2023 to a circumferential edge of the first cavity opening 2022. The cavity bottom wall 2023 is the innermost bottom wall of the first concave cavity 2021. The filter 201 composed of the cylinder 210 and the filter head 220 can be vertically placed on the filter paper 202 from the first cavity opening 2022 of the filter paper 202. Before the pushing member 320 pushes the filter 201 and the filter paper 202 to move towards the closed portion 102, there is a spacing between the bottom of the filter head 220 and the cavity bottom wall 2023 of the filter paper 202, i.e., before the pushing member 320 is pressed to move downwards, the bottom of the filter 201 does not directly contact the cavity bottom wall 2023 of the filter paper 202, but there is a certain space that can be compressed and folded. In this embodiment, the filter paper 202 has the shape of the first concave cavity 2021, which is beneficial to quickly wrap the filter paper 202 outside the filter head 220 through the first concave cavity 2021.

[0101] Referring to Figures 3 to 10 As shown, as an implementation form, the filter head 220 includes a connecting section 221, a sealing section 223 and a filtering section 222 arranged in sequence along the axial direction, i.e., the connecting section 221, the sealing section 223 and the filtering section 222 are arranged in sequence along the vertical direction. The connecting section 221 is detachably connected with the cylinder 210. The filtering section 222 is formed with a plurality of filtering holes for liquid to pass through. The first sealing ring 400 is sleeved outside the sealing section 223 to seal the cooperation gap between the sealing section 223 and the inner side wall of the accommodating cavity 103 when the filter assembly 200 is arranged in the accommodating cavity 103. The filter paper 202 is used to at least detachably wrap outside the filtering section 222 or wrap outside the filtering section 222 and the first sealing ring 400, i.e., the filter paper 202 at least wraps outside the filtering section 222 and the first sealing ring 400 with the first cavity opening 2022 towards the first opening 101. In this embodiment, the filter paper 202 is arranged to wrap outside the filtering section 222 and the first sealing ring 400, so that the filtering function of the filter paper 202 on the mixed liquid can be ensured, and the first sealing ring 400 can be prevented from being contaminated by residues through the filter paper 202, thereby facilitating to further reduce the cleaning difficulty of the brewing cup 10 after use. Of course, as an alternative implementation form, the filter paper 202 can be arranged to wrap outside the filtering section 222 only without wrapping the first sealing ring 400.

[0102] Referring to Figures 3 to 10As shown, as an implementation, the filter paper 202 and the filter head 220 satisfy at least one of the following conditions: the minimum inner diameter d1 of the first recess cavity 2021 is less than the outer diameter d3 of the filter section 222 toward the bottom of the closed portion 102, and the depth h1 of the first recess cavity 2021 is greater than the height h2 of the filter section 222. The depth h1 of the first recess cavity 2021 is the distance between the first cavity opening 2022 and the cavity bottom wall 2023. The height h2 of the filter section 222 is the distance between the top end and the bottom end of the filter section 222, i.e., the vertical extension of the filter section 222. By setting the minimum inner diameter d1 of the first recess cavity 2021 to be less than the outer diameter d3 of the bottom of the filter section 222, the bottom of the filter section 222 cannot enter the part of the first recess cavity 2021, so that the filter head 220 cannot completely enter the filter paper 202, i.e., the filter head 220 cannot directly contact the cavity bottom wall 2023 when it just enters the first recess cavity 2021, and there is a gap between the bottom of the filter head 220 and the cavity bottom wall 2023. By setting the depth h1 of the first recess cavity 2021 to be greater than the height h2 of the filter section 222, the filter head 220 also cannot completely enter the filter paper 202, and there is a gap between the bottom of the filter head 220 and the cavity bottom wall 2023. It can be seen that by setting the minimum inner diameter d1 of the first recess cavity 2021 to be less than the outer diameter d3 of the bottom of the filter section 222 and setting the depth h1 of the first recess cavity 2021 to be greater than the height h2 of the filter section 222, the purpose of having a space between the filter paper 202 and the bottom of the filter head 220 that can be compressed and folded is achieved, so that the bottom of the filter paper 202 can be squeezed and folded to form a wrinkle shape during the process of the pushing member 320 pushing the filter member 200 toward the closed portion 102, thereby facilitating further reducing the pushing force required by the user to push the filter member 200 toward the closed portion 102 by the pushing member 320.

[0103] Referring to Figures 6 to 10 As shown, as an implementation, the minimum inner diameter d1 of the first recess cavity 2021 is less than the outer diameter d3 of the bottom of the filter section 222 toward the closed portion 102, and the depth h1 of the first recess cavity 2021 is greater than the height h2 of the filter section 222, so that the filter paper 202 is better formed into a wrinkle structure 2026 when being pressed. The minimum inner diameter d1 of the first recess cavity 2021 is the inner diameter of the cavity bottom wall 2023, i.e., the inner diameter of the cavity bottom wall 2023 is less than the outer diameter d3 of the bottom of the filter section 222.

[0104] Referring to Figures 6 to 10As shown, as an implementation form, the depth h1 of the first cavity 2021 is greater than the sum of the height h2 of the filtering section 222 and the height h3 of the sealing section 223, so that the filtering paper 202 can be folded in the space between the bottom of the filter 201 and the filtering paper 202, and the filtering paper 202 can be wrapped around the filtering section 222 and the first sealing ring 400 at the same time.

[0105] Referring to Figure 6 , Figure 7 and Figure 10 As an implementation form, the maximum inner diameter d8 of the first cavity 2021 is greater than or equal to the maximum outer diameter d4 of the filtering section 222, so that the filtering paper 202 can be wrapped around the filtering section 222.

[0106] As an implementation form, the first cavity 2021 extends from the first cavity opening 2022 to the cavity bottom wall 2023 in a gradually decreasing diameter, that is, the first cavity 2021 is tapered, the inner diameter of the first cavity 2021 gradually decreases from top to bottom, that is, the top of the first cavity 2021 is the largest part of the inner diameter of the first cavity 2021, the inner diameter of the top of the first cavity 2021 is greater than or equal to the maximum outer diameter of the filtering section 222, and the bottom of the first cavity 2021 is the smallest part of the inner diameter of the first cavity 2021, so that the filtering section 222 can be better inserted into the filtering paper 202.

[0107] Referring to Figure 5 , Figure 10 and Figure 11 As an implementation form, the filter head 220 further forms a second cavity 224, which extends from the connecting section 221 to the sealing section 223 and the filtering section 222. The second cavity 224 is concave from the top of the filter head 220. The plurality of filtering holes formed on the filtering section 222 are respectively communicated with the second cavity 224. The second cavity 224 is arranged so that during the process that the pushing member 320 pushes the filtering component 200 to move towards the closed part 102, the liquid can flow into the barrel 210 through the filtering paper 202, the filtering holes and the second cavity 224 in sequence.

[0108] Referring to Figure 9 , Figure 10 and Figure 11As shown, as the first embodiment of the filter section 222, the filter section 222 comprises a first filter bottom wall 2221 and a first filter side wall 2222, the first filter side wall 2222 extending from the circumferential edge of the first filter bottom wall 2221 to the sealing section 223. The filter holes formed by the filter section 222 comprise a plurality of first filter holes 2223 formed in the first filter bottom wall 2221 and communicated with the second cavity 224 and a plurality of second filter holes 2224 formed in the first filter side wall 2222 and communicated with the second cavity 224, i.e. the first filter bottom wall 2221 is formed with the plurality of first filter holes 2223 and the first filter side wall 2222 is formed with the plurality of second filter holes 2224. In this embodiment, the filter holes are provided on both the first filter bottom wall 2221 and the first filter side wall 2222 of the filter section 222, which can facilitate increasing the filter area of the filter head 220 and reducing the weight and material usage of the filter head 220. Of course, in specific applications, as an alternative embodiment, the filter holes formed by the filter section 222 can only comprise the plurality of first filter holes 2223 formed in the first filter bottom wall 2221 and communicated with the second cavity 224 or only comprise the plurality of second filter holes 2224 formed in the first filter side wall 2222 and communicated with the second cavity 224, without providing the filter holes on both the first filter bottom wall 2221 and the first filter side wall 2222.

[0109] As a further embodiment of the first embodiment of the filter section 222, the first filter side wall 2222 extends from the circumferential edge of the first filter bottom wall 2221 to the sealing section 223 in a gradually increasing diameter, i.e. the outer diameter of the filter section 222 gradually decreases from top to bottom, the top of the filter section 222 is the largest part of the outer diameter of the filter section 222, and the bottom of the filter section 222 is the smallest part of the outer diameter of the filter section 222. The inner diameter of the top of the first cavity 2021 is greater than the outer diameter d3 of the bottom of the filter section 222 and greater than or equal to the outer diameter d4 of the top of the filter section 222, and the inner diameter d1 of the bottom of the first cavity 2021 is less than the outer diameter d3 of the bottom of the filter section 222. In this embodiment, the filter section 222 is arranged in a conical structure with the top larger and the bottom smaller, which can facilitate guiding the filter head 220 to be better arranged in the filter paper 202 and facilitating guiding the filter member 200 to be arranged in the cup body 100. Of course, in specific applications, as an alternative embodiment, the shape of the filter section 222 is not limited to this, for example, as an alternative embodiment, the first filter side wall 2222 extends from the circumferential edge of the first filter bottom wall 2221 to the sealing section 223 in a constant diameter, i.e. the filter section 222 has a cylindrical shape; or, as other alternative embodiments, the filter section 222 can also be arranged in a spherical shape or other irregular shapes.

[0110] Referring to Figure 3 and Figures 12 to 14As shown, as the second embodiment of the filtering section 222, the filtering head 220 is further formed with a second cavity 224 and a third cavity 225. The second cavity 224 is recessed from the connecting section 221 to the sealing section 223 and the filtering section 222, and the third cavity 225 is recessed at the bottom of the filtering section 222, i.e. the second cavity 224 is recessed downward from the top of the filtering head 220, and the third cavity 225 is recessed upward from the bottom of the filtering head 220. The second cavity 224 has a second cavity opening arranged upward, and the third cavity 225 has a third cavity opening arranged downward. The filtering section 222 includes a second filtering bottom wall 2225, a second filtering side wall 2226 and a third filtering side wall 2227, the second filtering side wall 2226 forms the outer peripheral wall of the filtering section, the second filtering bottom wall 2225 and the third filtering side wall 2227 enclose to form the third cavity 225, and the third filtering side wall 2227 extends from the bottom end of the second filtering side wall 2226 to the peripheral edge of the second filtering bottom wall 2225 towards the second cavity 224. The plurality of filtering holes on the filtering section 222 includes a plurality of third filtering holes 2228 formed on the second filtering bottom wall 2225 and communicated with the second cavity 224, a plurality of fourth filtering holes 2229 formed on the second filtering side wall 2226 and communicated with the second cavity 224, and a plurality of fifth filtering holes 2220 formed on the third filtering side wall 2227 and communicated with the second cavity 224. The second filtering bottom wall 2225 and the third filtering side wall 2227 are located inside the second filtering side wall 2226 in the radial direction of the filtering section 222. The third filtering side wall 2227 and the second filtering side wall 2226 are spaced apart from each other except that their bottom ends are connected, i.e. the third filtering side wall 2227 and the second filtering side wall 2226 are not the same side wall. In this embodiment, by recessing the third cavity 225 upward from the bottom of the filtering head 220, and arranging filtering holes on the inner side wall of the third cavity 225 (i.e. the third filtering side wall 2227) and the bottom wall of the third cavity 225 (i.e. the second filtering bottom wall 2225), and at the same time arranging filtering holes on the outer side wall of the filtering section 222 (i.e. the second filtering side wall 2226), it is equivalent to forming an additional side wall (i.e. the third filtering side wall 2227) for arranging filtering holes by the upward recess of the third cavity 225, so as to not only ensure that the filtering section 222 can form a large enough filtering area, but also facilitate reducing the height of the filtering section 222. Compared with the first embodiment of the filtering section 222, in this embodiment, the size of the space formed between the outer side wall of the filtering section 222 and the inner side wall of the cup body 100 can be reduced, so as to facilitate reducing the accumulation of liquid in the space formed between the outer side wall of the filtering section 222 and the inner side wall of the cup body 100, and further facilitate improving the drying and compaction effect of the residues being pressed.

[0111] Referring to Figure 3 and Figure 14As shown, in a further embodiment of the second implementation of the filter section 222, the height h4 of the filter section 222 is less than or equal to the height h5 of the connecting section 221. The height h4 of the filter section 222 is the vertical distance between the top and bottom ends of the second filter sidewall 2226, i.e., the axial length of the filter section 222. The height h5 of the connecting section 221 is the vertical distance between the top and bottom ends of the connecting section 221, i.e., the axial length of the connecting section 221. In this embodiment, by controlling the height h4 of the filter section 222 to be relatively small, it is more conducive to reducing the space formed between the outer wall of the filter section 222 and the inner wall of the cup body 100, thereby further improving the drying and compaction effect formed by the pushing of residue.

[0112] Reference Figure 14 As shown, in one embodiment, the height h4 of the filter section 222 is less than or equal to the height h6 of the sealing section 223. The height h6 of the sealing section 223 is the vertical distance between the top and bottom ends of the sealing section 223, i.e., the axial length of the sealing section 223. This embodiment allows for further control of the height h4 of the filter section 222 to be even smaller, thereby further improving the drying and compaction effect of the residue being pushed and compressed.

[0113] Reference Figure 3 and Figure 14 As shown, in one embodiment, the maximum outer diameter d6 of the second filter sidewall 2226 is smaller than the outer diameter d7 of the end of the sealing section 223 furthest from the connecting section 221. That is, the maximum outer diameter d6 of the second filter sidewall is smaller than the bottom outer diameter of the sealing section 223. This ensures that the second filter sidewall 2226 does not extend downwards from the bottom outer edge of the sealing section 223, but rather from a portion of the bottom wall of the sealing section 223 that is at a certain distance from the outer edge of the bottom wall. This facilitates better placement of the filter 201 on the filter paper 202 and allows the filter paper 202 to better cover the filter section 222 and the first sealing ring 400 during the pressing process. Of course, in specific applications, as an alternative embodiment, the maximum outer diameter d6 of the second filter sidewall 2226 can also be set to be equal to the outer diameter d7 of the end of the sealing section 223 furthest from the connecting section 221.

[0114] In one implementation, the second filter sidewall 2226 extends from the bottom wall of the sealing section 223 in a direction away from the connecting section 221 with a gradually decreasing diameter. That is, the second filter sidewall 2226 has a tapered structure that is larger at the top and smaller at the bottom, which facilitates better placement of the filter head 220 on the filter paper 202. Of course, in specific applications, the shape of the second filter sidewall 2226 is not limited to this. For example, as an alternative implementation, the second filter sidewall 2226 extends from the bottom wall of the sealing section 223 in a direction away from the connecting section 221 with a constant diameter. That is, the second filter sidewall 2226 is cylindrical.

[0115] As an implementation, the third filter side wall 2227 extends from the bottom end of the second filter side wall 2226 of the sealing section 223 to the circumferential edge of the second filter bottom wall with a tendency of gradually reducing diameter, i.e. the third filter side wall 2227 is a tapered structure with the top smaller than the bottom, so that the second filter side wall 2226 and the third filter side wall 2227 can form a larger spacing, facilitating the formation of filter holes in the second filter side wall 2226 and the third filter side wall 2227, respectively. The cross section of the second filter side wall 2226 and the third filter side wall 2227 is in the shape of an inverted V. Of course, the shape of the third filter side wall 2227 is not limited thereto in specific applications. For example, as an alternative implementation, the third filter side wall 2227 extends from the bottom end of the second filter side wall 2226 of the sealing section 223 to the circumferential edge of the second filter bottom wall with a constant diameter, i.e. the third filter side wall 2227 is in the shape of a cylinder.

[0116] As an implementation, the distribution area of the plurality of filter holes of the filter section 222 (i.e. all the filter holes of the filter section 222) is greater than or equal to 20% of the surface area of the filter section 222, so as to ensure that the filter section 222 has a large enough filter area, thereby facilitating the pushing member 320 to be pressed down without too much difficulty.

[0117] As an implementation, the distribution area of the plurality of filter holes of the filter section 222 is greater than or equal to 32% of the surface area of the filter section, so as to further improve the filtering efficiency and the smoothness of the pushing member being pressed down.

[0118] As an implementation, the distribution area of the plurality of filter holes of the filter section 222 is greater than or equal to 45% of the surface area of the filter section, so as to further improve the filtering efficiency and the smoothness of the pushing member being pressed down.

[0119] As an implementation, the outer side wall of the sealing section 223 is formed with a first annular groove, and the first sealing ring 400 is in clamping engagement with the first annular groove.

[0120] As an implementation, the connecting section 221 is formed with external threads, and the bottom end of the barrel 210 is formed with internal threads, and the connecting section 221 is threadedly connected with the barrel 210.

[0121] Referring to Figs. Figure 3 , Figure 8 and Figure 15 As an implementation, the maximum outer diameter d2 of the filter paper 202 is greater than the inner diameter d5 of the first opening 101, i.e. the outer diameter of the top of the filter paper 202 is greater than the inner diameter d5 of the first opening 101, so that when the filter paper 202 is just placed on the cup body 100, it will not completely enter the accommodating cavity 103 of the cup body 100, thereby facilitating the fault tolerance of the placement of the filter paper 202.

[0122] Referring to Figure 3 , Figure 4 , Figure 5 and Figure 8 , as an implementation form, the top edge of the filter paper 202 is formed with a flange 2025 extending outward, which is used to lap the top edge (i.e. the edge of the first opening) of the cup body 100 before the pushing member 320 pushes the filter 201 and the filter paper 202 to move towards the closing part 102. Specifically, the filter paper 202 includes a filter paper body 2027 and a flange 2025, which is an annular structure extending horizontally from the top edge of the filter paper body in a direction away from the central axis of the filter paper body 2027. The outer diameter of the flange 2025 is the maximum outer diameter d2 of the filter paper 202. The provision of the flange 2025, on the one hand, allows the user to place it on the cup body 100 at will and makes the filter paper 202 lap the top edge of the cup body 100 well, without worrying about the placement position being inappropriate, thereby facilitating to improve the fault tolerance of the placement of the filter paper 202, i.e. when lapping the filter paper 202 on the top of the cup body 100, the flange 2025 can make the user easily let the filter paper 202 fall into the appropriate position, which is conducive to improving the convenience of the user using the brewing cup 10 and reducing the difficulty of the user using the brewing cup 10, and on the other hand, makes the filter paper 202 better cover the first sealing ring 400.

[0123] As an implementation form, the filter paper body 2027 is conical, and the filter paper body 2027 extends in a trend that the diameter gradually decreases from top to bottom, i.e. the filter paper body 2027 is a conical structure with the top being large and the bottom being small, which facilitates the filter paper 202 to lap the top edge of the cup body 100 more smoothly.

[0124] As an implementation form, the outer diameter of the cylinder body 210 is equal to the inner diameter of the accommodating cavity 103, so that after the cylinder body 210 is arranged in the accommodating cavity 103, it is in contact with the inner side wall of the accommodating cavity 103. Of course, in specific applications, there can be a certain gap between the outer diameter of the cylinder body 210 and the inner diameter of the accommodating cavity 103.

[0125] Referring to Figure 18 and Figure 20 , as an implementation form, the cylinder body 210 is also formed with a strip-shaped opening 213 extending from the outer side wall to the inner side wall, which can facilitate to strengthen the strength of the cylinder body 210.

[0126] Referring to Figures 16 to 20As shown, as an embodiment, the inner side wall of the barrel 210 is provided with at least two first abutting portions 211 which are distributed along the circumference; the outer circumference of the pushing member 320 is provided with at least two second abutting portions 323 which are arranged along the circumference; when the second abutting portions 323 are opposite to and abut against the first abutting portions 211, the pushing member 320 can push the barrel 210 to drive the filter head 220 and the filter paper 202 to move along the first opening 101 towards the direction of the closed portion 102 under the action of external force. In the present embodiment, the abutting cooperation between the second abutting portions 323 and the first abutting portions 211 realizes the abutting cooperation between the pushing member 320 and the filter 201, and the bottom of the pushing member 320 can be supported on the top of the first abutting portions 211, at this time, the pushing member 320 can push the first abutting portions 211 to drive the barrel 210 to move downward under the action of external force. The first abutting portions 211 can be protrusions or protrusions 2112 or stepped surfaces or protruding ribs provided on the inner side wall of the barrel 210.

[0127] As an embodiment, the number of the first abutting portions 211 is an integer multiple of the number of the second abutting portions 323, and the integer multiple is greater than or equal to one, that is, the number of the first abutting portions 211 can be equal to the number of the second abutting portions 323, or can be two times or more integer times of the number of the second abutting portions 323. For example, the number of the first abutting portions 211 and the number of the second abutting portions 323 can both be four, or both be three, or both be two, or both be five, or both be six or even more; or the number of the first abutting portions 211 is four, and the number of the second abutting portions 323 is two; or the number of the first abutting portions 211 is six, and the number of the second abutting portions 323 is three.

[0128] As an embodiment, the first abutting portions 211 are spaced apart from the end of the barrel 210 away from the filter, that is, there is a spacing between the first abutting portions 211 and the top of the barrel 210, and the first abutting portions 211 are not flush with the edge of the top of the barrel 210, so that when the second abutting portions 323 abut against the first abutting portions 211, the pushing member 320 is partially embedded in the barrel 210, so that the pushing member 320 can be horizontally limited by the barrel 210, thereby preventing the pushing member 320 from slipping off the filter member 200 during the movement of the pushing member 320 towards the closed portion 102, and ensuring the stability and reliability of the movement of the pushing member 320 to push the filter member 200.

[0129] Reference Figure 2 , Figure 16 and Figure 17As shown, as a first embodiment of the pushing member 320, the pushing member 320 comprises a transverse plate body 321 and at least two vertical plate bodies 322. One end of the transverse plate body 321 is connected to one end of the at least two vertical plate bodies 322, i.e. the bottom surface of the transverse plate body 321 is connected to the top end of the at least two vertical plate bodies 322. The inner side of the at least two vertical plate bodies 322 close to the central axis of the transverse plate body 321 meets, and the outer peripheral side of the at least two vertical plate bodies 322 away from the central axis of the transverse plate body 321 is arranged in a spaced manner in the circumferential direction; each vertical plate body 322 is provided with a second abutting portion 323 on the outer peripheral side away from the central axis of the transverse plate body 321, and the second abutting portion 323 is arranged close to the end of the vertical plate body 322 away from the transverse plate body 321, i.e. the at least two vertical plate bodies 322 extend radially outward from the meeting surface of each vertical plate body 322. The provision of the at least two vertical plate bodies 322 mainly facilitates cooperation with the filter component 200, which is beneficial to reducing the material usage and weight of the pushing member 320. In an alternative embodiment, the transverse plate body 321 can also be provided in the form of a rod.

[0130] Referring to Figures 16 to 18 As shown, as an embodiment, the first abutting portion 211 is a first protrusion 2111, which extends in an arc shape along the circumferential direction of the inner side wall of the cylinder body 210; the second abutting portion 323 is a second protrusion 3231, which is provided on the outer peripheral side of the vertical plate body 322 and extends from the end of the vertical plate body 322 away from the transverse plate body 321; the circumferential extension length of the second protrusion 3231 is greater than the circumferential extension length of the first protrusion 2111, and the second protrusion 3231 is used to abut against the first protrusion 2111 to realize the abutment of the second abutting portion 323 and the first abutting portion 211. The circumferential extension length of the first protrusion 2111 is the dimension of the first protrusion 2111 extending in the horizontal circumferential direction. The circumferential extension length of the second protrusion 3231 is the dimension of the second protrusion 3231 extending in the horizontal circumferential direction. In this embodiment, the circumferential extension length of the second protrusion 3231 is set to be greater than the circumferential extension length of the first protrusion 2111, which is beneficial to preventing the first protrusion 2111 from easily slipping off the second protrusion 3231.

[0131] As an embodiment, the number of vertical plate bodies 322 is four, and the outer peripheral side of each vertical plate body 322 is formed with a second protrusion 3231. Of course, in specific applications, the number of vertical plate bodies 322 is not limited to four, for example, as an alternative embodiment, the number of vertical plate bodies 322 is three; or, the number of vertical plate bodies 322 is two; or, the number of vertical plate bodies 322 is five or six or more.

[0132] In the first embodiment of the aforementioned pushing member 320, the pushing member 320 adopts a combination of a horizontal plate 321 and at least two vertical plates 322, and the second abutting portion 323 is a protrusion protruding from the outer periphery of the vertical plate 322. Of course, in specific applications, the arrangement of the pushing member 320 and the second abutting portion 323 is not limited to this. For example, refer to... Figure 19 As shown, in a second embodiment of the pusher 320, the pusher 320 includes a rod 324, and a second abutment portion 323 is provided on the outer side wall of the rod 324. In this embodiment, the pusher 320 adopts a rod, which has a simple structure.

[0133] Reference Figure 2 , Figure 19 and Figure 20 As shown, in a further embodiment of the second implementation of the pusher 320, the first abutting part 211 is a protrusion 2112, which protrudes from the inner sidewall of the cylinder 210; the second abutting part 323 is a groove 3232, which has a slot 3233 facing the closing part 102 and a first groove wall 3234 spaced apart from the slot 3233. The protrusion 2112 is used to be engaged in the groove 3232 and abut against the first groove wall 3234 to achieve the abutment between the second abutting part 323 and the first abutting part 211. In this embodiment, the cooperation between the protrusion 2112 and the groove 3232 can achieve the abutting cooperation between the first abutting part 211 and the second abutting part 323, and also helps to prevent the second abutting part 323 from slipping off the first abutting part 211.

[0134] In one embodiment, the protrusion 2112 is a cylindrical protrusion 2112, which has a simple structure and is easy to manufacture. Of course, the shape of the protrusion 2112 is not limited to this. For example, as an alternative embodiment, the protrusion 2112 can also be a semi-cylindrical protrusion 2112 or a rectangular protrusion 2112, etc.

[0135] Reference Figure 2 , Figure 19 and Figure 20As shown, as an embodiment, the clamping groove 3232 comprises a mounting groove segment 3235 and a clamping groove segment 3236, the mounting groove segment 3235 extends from the slot opening 3233 towards the first groove wall 3234, and the clamping groove segment 3236 extends horizontally from the first groove segment. The clamping groove 3232 is further formed with a second groove wall 3237, a third groove wall 3238, and a fourth groove wall 3239, the first groove wall 3234 and the second groove wall 3237 are oppositely arranged, the third groove wall 3238 and the fourth groove wall 3239 are oppositely arranged, the third groove wall 3238 is connected to one end of the first groove wall 3234 and the second groove wall 3237, and the first groove wall 3234, the second groove wall 3237, and the third groove wall 3238 enclose the clamping groove segment 3236. The protrusion 2112 is assembled with the clamping groove 3232 in the following way: the protrusion 2112 is slid into the mounting groove segment 3235 from the slot opening 3233, and then is clamped into the clamping groove segment 3236 from the mounting groove segment 3235, so as to prevent the protrusion 2112 from being easily slid out of the clamping groove 3232.

[0136] Referring to Figure 2 and Figure 19 As an embodiment, the rod body 324 is formed with a hollow inner hole 3241 along the central axis thereof, i.e., the rod body 324 is a hollow rod body, so as to facilitate reducing the weight and material consumption of the pushing member 320.

[0137] Referring to Figure 1 , Figure 2 , Figure 17 and Figure 19As shown, as an embodiment, the brewing cup 10 further comprises a top cover 310 which is detachably connected to the cup body 100, and when the top cover 310 is connected to the cup body 100, the top cover 310 seals the first opening 101 and forms a closed space with the cup body 100. In this embodiment, by arranging the top cover 310 to seal the first opening 101 of the cup body 100 and form a closed space with the cup body 100, when the brewing cup 10 is loaded with liquid, even if the brewing cup 10 is inverted, the liquid will not leak out of the first opening 101 at the top of the brewing cup 10, so that the brewing cup 10 can be used not only to brew the brewing powder into a drinkable liquid, but also as a portable liquid storage container for loading a drinkable liquid, thereby effectively expanding the function of the brewing cup 10. In addition, the top cover 310 seals the cup body 100, so that the brewing cup 10 has a sealing capability to form a closed space, so that in specific applications, after the user puts the brewing powder and the liquid solvent into the cup body 100, the user can first seal the cup body 100 with the top cover 310, and then shake the brewing cup 10 to mix the brewing powder and the liquid solvent, thereby more quickly and fully mixing the brewing powder and the liquid solvent. The mixing operation process does not need to rely on other articles, and the operation is simple and convenient; and when used for making coffee, the sufficient mixing of the brewing powder and the liquid solvent helps to improve the concentration and taste of the coffee.

[0138] As an embodiment, after the brewing powder and the liquid solvent are added into the cup body 100, the brewing powder and the liquid solvent are mixed by shaking the brewing cup 10. This mixing method can improve the extraction efficiency compared to the stirring mixing method, especially in the preparation process of cold brew coffee, which achieves the effect of being made within one minute. In specific applications, after the brewing powder and the liquid solvent are added into the cup body 100, the top cover 310 is first sealed to the first opening 101, and then the brewing powder and the liquid solvent are shaken and mixed by shaking the brewing cup 10, to prevent the liquid from being sprayed out of the cup body 100 during shaking.

[0139] As an implementation, the end of the pusher 320 away from the closed portion 102 can be detachably connected to the top cover 310, that is, the end of the pusher 320 away from the closed portion 102 can be detachably connected to the top cover 310, so that the pusher 320 can be connected to the top cover 310 or detached and removed from the top cover 310 to achieve separation from the top cover 310. The pusher 320 is connected to the top cover 310, and the top cover device 300 can be assembled. In specific applications, after the brewing powder and the liquid solvent are added into the cup body 100 and before the brewing powder and the liquid solvent are mixed by shaking the brewing cup 10, the pusher 320 is first detached and removed from the top cover 310, and the top cover 310 is separately sealed to the first opening 101. After the shaking and mixing operation, the top cover 310 is detached, the filter member 200 is placed at the top end of the cup body 100, and then the pusher 320 is assembled to the top cover 310 to form the top cover device 300 attached to the filter member 200. With this scheme, the pusher 320 can not be contaminated during the shaking and mixing process, thereby facilitating the cleaning of the pusher 320. In addition, when the filter member 200 is attached to the cup body 100 and the pusher 320 abuts against the filter member 200, the user can drive the pusher 320 to push the filter member 200 to move into the accommodation cavity 103 by applying force to the top of the top cover 310. Of course, as an alternative implementation, the pusher and the top cover 310 can be integrally formed.

[0140] As an implementation, the end of the pusher 320 away from the closed portion 102 (i.e., the top of the pusher 320) is detachably connected to the top cover 310 by rotating buckling or threaded connection.

[0141] As an implementation form, the top cover device 300 formed by assembling the pushing member 320 and the top cover 310 is used to drive the filter component 200 to move relative to the cup body 100 under the action of an external force, that is, the user pushes the filter component 200 to move downward by pressing the top cover 310 and the pushing member 320 to move downward, instead of pressing the pushing member 320 alone. In this way, the top cover 310 can be used to increase the pressing area of the user, thereby facilitating the operation comfort and use convenience of the user in using the brewing cup 10. In a specific application, when the brewing cup 10 is needed to brew the brewing powder, the filter component 200 and the top cover device 300 can be removed from the cup body 100, the brewing powder and the liquid solvent are added into the cup body 100, and after the brewing powder and the liquid solvent are fully mixed, the filter component 200 is placed at the top end of the cup body 100, and then the top cover device 300 is attached to the filter component 200. The filter component 200 is driven by the top cover device 300 to move toward the closed part 102 of the cup body 100, so that the filter component 200 pushes the residues in the mixed liquid in the cup body 100 toward the bottom of the cup body 100. After the filter component 200 is moved in place, the top cover device 300 can be removed. At this time, since the filter component 200 remains in the cup body 100 to maintain the separation state of the liquid and the residues, the user can directly use the cup body 100 to drink the brewed liquid. That is, the brewing cup 10 can be used as a brewing device and as a drinking container, without the need to additionally increase a container as a drinking container, thereby improving the convenience of the user in brewing the brewing powder and drinking the brewed liquid.

[0142] Referring to Figure 1 , Figure 2 and Figure 17 As an implementation form, the top cover 310 is formed with a holding part 311 for the user to hold to push the pushing member 320 to drive the filter component 200 to move along the first opening 101 toward the closed part 102. The outer diameter of the holding part 311 is greater than or equal to 50% of the inner diameter of the first opening 101. In this embodiment, the holding part 311 with an outer diameter greater than or equal to 50% of the inner diameter of the first opening 101 is formed on the top cover 310 for the user to press the top cover device 300 to move, which greatly increases the pressing area compared with the way of pressing a small ball on a teapot.

[0143] As an implementation form, the outer diameter of the holding part 311 is greater than or equal to 60% of the inner diameter of the first opening 101.

[0144] As an implementation form, the outer diameter of the holding part 311 is greater than or equal to 80% of the inner diameter of the first opening 101.

[0145] As an implementation, the outer diameter of the holding portion 311 is greater than or equal to the inner diameter of the first opening 101.

[0146] As an implementation, the outer diameter of the holding portion 311 is substantially equal to the inner diameter of the first opening 101, so that the acting area acting on the top cover device 300 when a user presses the top cover device 300 to move can be maximized while the performance of the top cover 310 covering the first opening 101 is taken into account, thereby facilitating the improvement of the operation comfort of the user pressing the top cover device 300 to move.

[0147] Referring to FIGS. 1 and 2, Figure 2 and Figure 5 As an implementation, the brewing cup 10 further includes a second sealing ring 500, which is arranged between the top cover 310 and the cup body 100 to seal the fitting gap between the top cover 310 and the cup body 100 when the top cover 310 covers the cup body 100. The arrangement of the second sealing ring 500 enables the top cover 310 to form a closed space with the cup body 100 when covering the cup body 100, so that the liquid loaded in the brewing cup 10 cannot leak out of the first opening 101 even if the brewing cup 10 is inverted, and the liquid in the cup body 100 cannot leak out of the first opening 101 when the brewing powder and the liquid solvent in the brewing cup 10 are shaken to mix, thereby ensuring the feasibility of shaking to mix.

[0148] As an implementation, the top cover 310 is formed with a second annular groove, and the second sealing ring 500 is in clamping fit with the second annular groove.

[0149] Referring to FIGS. 1 and 2, Figures 1 to 3As shown, as an implementation, the pushing member 320 has a first installation state and a second installation state. In the first installation state, the pushing member 320 is nested with the filtering component 200, so that the pushing member 320 and the filtering component 200 can be accommodated in the closed space. In the second installation state, the pushing member 320 abuts against the filtering component 200 in the direction of the first opening 101 towards the closed portion 102, and the pushing member 320 is at least partially exposed outside the accommodating cavity 103, so that the pushing member 320 can push the filtering component 200 to move in the direction of the first opening 101 towards the closed portion 102 under the action of an external force, so that the filter paper 202 pushes the residue in the mixed liquid in the accommodating cavity 103 towards the closed portion 102, and the liquid in the mixed liquid passes through the filter paper 202 into the space between the filter paper 202 and the first opening 101. The pushing member 320 is provided on the side of the top cover 310 towards the closed portion 102. In the first installation state, the top cover 310 is connected to the cup body 100 and seals the first opening 101. In the second installation state, the top cover 310 is spaced apart from the cup body 100. The present embodiment can meet different use requirements of the brewing cup 10 by providing the pushing member 320 with the first installation state and the second installation state. Specifically, since the pushing member 320 is nested with the filtering component 200 in the first installation state, the pushing member 320 and the filtering component 200 can be accommodated in the closed space enclosed by the top cover 310 and the cup body 100, thereby facilitating the reduction of the volume of the brewing cup 10, and thus the portability of the brewing cup 10 can be improved by using the first installation state of the pushing member 320. Since the pushing member 320 abuts against the filtering component 200 in the direction of the first opening 101 towards the closed portion 102 in the second installation state, the pushing member 320 can push the filtering component 200 to move in the direction of the first opening 101 towards the closed portion 102 under the action of an external force, so that the brewing function of the brewing cup 10 on the brewing powder can be realized by using the second installation state of the pushing member 320. After the pushing member 320 pushes the filtering component 200 to move into position, the top cover 310 and the pushing member 320 can be removed, and at this time, since the filtering component 200 remains in the cup body 100 to maintain the separation state of the liquid and the residue, the user can directly use the cup body 100 to drink the brewed liquid, that is, the brewing cup 10 can be used as a brewing device and as a drinking container, without the need for an additional container as a drinking container, thereby improving the convenience of the user in using the brewing cup 10.
