Description

Technical Field

[0001] This utility model relates to the field of coffee powder blowing tools, and in particular to a coffee powder blowing disc and a coffee powder cup assembly having the coffee powder blowing disc. Background Technology

[0002] During the coffee extraction process, the user places coffee powder into the brewing chamber of the coffee maker. The bottom end of the coffee maker has a liquid outlet that is connected to the brewing chamber, so that high-temperature and high-pressure water is supplied to the brewing chamber to extract the coffee powder. Under the brewing of high-temperature and high-pressure water, the coffee powder in the brewing chamber dissolves and extracts soluble compounds (such as aromatic substances, oils, acids, etc.) from the coffee beans. The extracted coffee liquid flows out into the coffee cup through the liquid outlet of the coffee maker.

[0003] After coffee extraction, the user inverts the coffee cup so that the opening of the brewing chamber faces downwards, then shakes and taps the cup to pour out the coffee puck (coffee grounds). However, the coffee puck, after being extracted by high-temperature, high-pressure water, tends to stick to the walls of the brewing chamber. The user needs to shake and tap the cup forcefully to remove the grounds, increasing the effort required to pour them out and impacting user satisfaction. Furthermore, the forceful shaking and tapping causes the grounds to break apart and scatter over a wide area, requiring extensive cleaning and increasing the user's workload. Summary of the Invention

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0031] First embodiment of coffee powder cup assembly: See Figure 1 and Figure 9 This embodiment discloses a coffee powder cup assembly, including a powder cup structure 20 and a coffee powder puck blower 10.

[0032] In this embodiment, the powder cup structure 20 includes a stainless steel cup 21 and a plastic cup sleeve 22. The plastic cup sleeve 22 seals and covers the outside of the stainless steel cup 21 to insulate the stainless steel cup 21 from heat. The stainless steel cup 21 has a cavity opening 211 and a brewing cavity 212 connected to the cavity opening 211. The brewing cavity 212 is used to hold coffee powder. The liquid outlet end of the stainless steel cup 21, which is opposite to the cavity opening 211, has a liquid outlet hole 213 that is connected to the brewing cavity 212. The support end 225 of the plastic cup sleeve 22, which is adjacent to the liquid outlet end of the stainless steel cup 21, has a clearance hole 221 that corresponds to the liquid outlet hole 213. The outer peripheral surface of the support end 225 of the plastic cup sleeve 22 is recessed and formed with a limiting ring groove 222, so that the end of the support end 225 of the plastic cup sleeve 22 away from the cavity opening 211 forms a limiting ring shoulder 223 adjacent to the limiting ring groove 222.

[0033] Furthermore, in this embodiment, the coffee powder pouch blower 10 includes an elastic capsule 11, a first one-way valve 113, and a second one-way valve 115. The elastic capsule 11 contains an elastic air chamber 111. The upper and lower ends of the elastic capsule 11 are respectively provided with an upper air inlet 112 and a lower air outlet 114 communicating with the elastic air chamber 111. In this embodiment, the first one-way valve 113 includes a first spring arm 1131 and a first valve plate 1132. The first spring arm 1131 is located within the elastic air chamber 111 and connected to the elastic capsule. Between the elastic capsule 11 and the first valve plate 1132, the first valve plate 1132 is located inside the elastic air chamber 111 and is positioned near the lower end opening of the upper air inlet 112. The first valve plate 1132 can abut against the upper end wall of the elastic air chamber 111 to seal the lower end opening of the upper air inlet 112. In this embodiment, an elastic ring 116 is provided protruding from the lower end of the elastic capsule 11. The elastic ring 116 contains a first annular cavity 1161, a second annular cavity 1162, and a third annular cavity 1163 connected in sequence. The first annular cavity 1161 is arranged around the outer periphery of the lower vent 114 and can communicate with the lower vent 114. The diameter of the second annular cavity 1162 is smaller than the diameter of the third annular cavity 1163 but larger than the diameter of the first annular cavity 1161. The lower end of the third annular cavity 1163 away from the second annular cavity 1162 has an opening 1169. The periphery of the second annular cavity 1162 adjacent to the third annular cavity 1163 is provided with a supporting shoulder 1164. The periphery of the third annular cavity 1163 is provided with a fastening device. The second one-way valve 115 in this embodiment includes a second spring arm 1151 and a second valve plate 1152. The second spring arm 1151 is located in the first annular cavity 1161 and connected between the elastic capsule 11 and the second valve plate 1152. The second valve plate 1152 is located in the first annular cavity 1161 and is disposed near the lower end opening of the lower vent 114. The second valve plate 1152 can abut against the upper end cavity wall of the first annular cavity 1161 to seal the lower end opening of the lower vent 114.

[0034] In this embodiment, during use, the user places the coffee powder cup structure 20 with the cavity opening 211 of the stainless steel cup 21 facing upwards, and puts coffee powder into the brewing chamber 212 of the stainless steel cup 21. High-temperature, high-pressure water is then supplied to the brewing chamber 212 of the stainless steel cup 21 to extract the coffee powder. Under the influence of the high-temperature, high-pressure water, the coffee powder in the brewing chamber 212 dissolves, extracting soluble compounds (such as aromatic substances, oils, acids, etc.) from the coffee beans. The extracted coffee liquid flows out through the outlet hole 213 of the stainless steel cup 21 into the coffee cup. Because the brewing chamber 212 is located inside the stainless steel cup 21, the deformation of the stainless steel cup 21 is very small when the coffee powder in the brewing chamber 212 is extracted by the high-temperature, high-pressure water. Furthermore, the stainless steel cup 21 is made of safe and healthy materials, thus ensuring safe use.

[0035] After coffee extraction is complete, the coffee puck, extracted by high-temperature and high-pressure water, adheres to the periphery of the brewing chamber 212 of the stainless steel cup 21. The user then inverts the coffee cup structure 20 so that the opening 211 of the stainless steel cup 21 faces downwards. When the coffee cup structure 20 is placed with the opening 211 facing downwards, the supporting end 225 of the plastic cup sleeve 22 of the coffee cup structure 20 is positioned upwards. The user then places the elastic ring 116 of the coffee puck blower 10 onto the plastic cup sleeve of the coffee cup structure 20. The support end 225 of the cup sleeve 22 allows the upper surface of the second annular cavity 1162 of the coffee powder blower 10 to press against the end face of the limiting ring shoulder 223 of the support end 225 of the cup sleeve 22, away from the cavity opening 211. The outer periphery of the limiting ring shoulder 223 of the support end 225 of the cup sleeve 22 is embedded in the second annular cavity 1162 of the coffee powder blower 10, while the outer periphery of the support ring shoulder 1164 of the coffee powder blower 10 is embedded in the limiting ring groove 222 of the support end 225 of the cup sleeve 22. This securely fastens and installs the coffee powder blower 10 in this embodiment. In this embodiment, the support end 225 of the cup sleeve 22 of the coffee powder cup structure 20 can compress the elastic capsule 11 of the coffee powder blower 10 so that the lower air outlet 114 of the coffee powder blower 10 is connected to the liquid outlet 213 of the stainless steel cup 21 of the coffee powder cup structure 20. Specifically, when the user compresses the elastic capsule 11 of the coffee powder blower 10, the first valve plate 1132 at the upper air inlet 112 of the coffee powder blower 10 abuts against the upper cavity wall of the elastic air chamber 111 under the compression of the air inside the elastic capsule 11, thereby controlling the lower air outlet 112. The end opening is sealed, and at the same time, the second valve plate 1152 at the lower air outlet 114 of the coffee powder blower 10 moves away from the lower end opening of the lower air outlet 114 under the compression of the air in the elastic capsule 11. This allows the air in the elastic capsule 11 to be sent from the lower air outlet 114 to the liquid outlet 213 of the stainless steel cup 21 to be blown into the brewing chamber 212 of the stainless steel cup 21. Under the pushing action of the airflow, the coffee powder in the brewing chamber 212 of the stainless steel cup 21 can be quickly detached and poured out of the brewing chamber 212 of the stainless steel cup 21, and the coffee powder is blown off completely.

[0036] Therefore, the coffee puck blower 10 of this embodiment can quickly and completely blow the coffee puck out of the brewing chamber 212 of the coffee cup, eliminating the need for the user to forcefully shake or tap the coffee cup to remove the coffee puck adhering to the cavity wall of the brewing chamber 212. This reduces the effort required for the user to pour the coffee puck out of the brewing chamber 212 and prevents the coffee puck from falling out in a fragmented state, thus reducing the user's cleaning work, improving user satisfaction, and increasing the enjoyment of the operation. Furthermore, the coffee puck blower 10 of this embodiment has a simple structure and operates stably and reliably.

[0037] Combination Figures 3 to 9In this embodiment, the coffee powder cake blowing disc 10 also includes a first mounting base 12. A first mounting hole 118 is formed through the upper end of the elastic capsule 11. The first mounting base 12 is fixedly disposed within the first mounting hole 118. An upper air inlet 112 is formed through the first mounting base 12. A first elastic arm 1131 is L-shaped and connects the first mounting base 12 and the first valve plate 1132, thereby improving the elastic movement capability of the first valve plate 1132. Specifically, in this embodiment, the first mounting base 12 is securely installed within the first mounting hole 118 by adhesive bonding.

[0038] Specifically, in this embodiment, the coffee powder cake blower 10 also includes a second mounting base 13. A second mounting hole 119 is formed through the lower end of the elastic capsule 11. The second mounting base 13 is fixedly disposed within the second mounting hole 119. A lower air outlet 114 is formed through the second mounting base 13. A second elastic arm 1151 is L-shaped and connects the second mounting base 13 and the second valve plate 1152, thereby improving the elastic movement capability of the second valve plate 1152. Specifically, in this embodiment, the second mounting base 13 is securely installed within the second mounting hole 119 by adhesive bonding.

[0039] To improve the smoothness and speed of the elastic ring 116 of the coffee powder blower 10 being fitted and installed into the powder cup structure 20, in this embodiment, the third annular cavity 1163 of the elastic ring 116 of the coffee powder blower 10 is inclined downwards at the cavity peripheral wall 1166 between the fastening ring rib 1165 and the opening 1169. The inclined downwards cavity peripheral wall 1166 can guide the elastic ring 116 to be fitted and installed into the powder cup structure 20 smoothly and quickly.

[0040] To further improve the smoothness and speed of the flexible ring 116 of the coffee powder blower 10 being fitted and installed into the powder cup structure 20, in this embodiment, the lower corner of the support shoulder 1164 in the flexible ring 116, away from the cavity wall of the second annular cavity 1162, is set with an arc angle 1167, and the upper end surface 1168 of the support shoulder 1164 is inclined upward. In this embodiment, the outer circumferential surface of the fastening rib 1165 in the flexible ring 116, away from the cavity wall of the third annular cavity 1163, is set with an arc shape.

[0041] To improve operational stability, the outer periphery of the elastic capsule 11 of the coffee powder blower 10 in this embodiment is provided with a plurality of anti-slip ribs 117 protruding from it. The plurality of anti-slip ribs 117 are arranged in concentric circles, which improves the appearance of the coffee powder blower 10.

[0042] In order to improve the airflow from the lower air outlet 114 of the coffee powder blower 10 to be delivered quickly and smoothly to the liquid outlet 213 of the stainless steel cup 21 so as to quickly enter the brewing chamber 212 of the stainless steel cup 21, thereby blowing the coffee powder in the brewing chamber 212 to blow the coffee powder out of the brewing chamber 212 completely and quickly, in this embodiment, the supporting end 225 of the cup sleeve 22 away from the cavity opening 211 is provided with a recessed groove 224 corresponding to the lower air outlet 114.

[0043] Second embodiment of coffee powder cup assembly: As an explanation of the second embodiment of the coffee powder cup assembly of this utility model, the following description only focuses on the differences from the first embodiment of the coffee powder cup assembly.

[0044] See Figure 10 This embodiment of the coffee powder cup assembly includes a powder cup structure 30 and a coffee powder puck blower 10. Specifically, the powder cup structure 30 includes a stainless steel cup 31 and a plastic cup sleeve 32. The plastic cup sleeve 32 seals and covers the outside of the stainless steel cup 31 to insulate the stainless steel cup 31 from heat. The stainless steel cup 31 has a cavity opening 311 and a brewing cavity 312 connected to the cavity opening 311. The brewing cavity 312 is used to hold coffee powder. The liquid outlet end of the stainless steel cup 31, which is opposite to the cavity opening 311, has a liquid outlet hole 313 that is connected to the brewing cavity 312. The support end 323 of the plastic cup sleeve 32, which is adjacent to the liquid outlet end of the stainless steel cup 31, has a clearance hole 321 that corresponds to the liquid outlet hole 313. The outer end face of the support end 323 of the plastic cup sleeve 32 has a protruding support ring rib 322.

[0045] After coffee extraction is complete, the coffee puck, extracted by high-temperature and high-pressure water, adheres to the cavity wall of the brewing chamber 312 of the stainless steel cup 31. The user then inverts the coffee cup structure 30 so that the cavity opening 311 of the stainless steel cup 31 faces downwards. When the coffee cup structure 30 is placed with the cavity opening 311 facing downwards, the support end 323 of the plastic cup sleeve 32 of the coffee cup structure 30 in this embodiment is positioned upwards. The user then places the elastic ring 116 of the coffee puck blower 10 onto the coffee cup structure 30. In the embodiment, the support end 323 of the plastic cup sleeve 32 of the coffee powder cup structure 30 allows the upper end face of the third annular cavity 1163 of the coffee powder blower 10 or the lower end face of the support ring shoulder 1164 of the coffee powder blower 10 to press against the support ring rib 322 of the plastic cup sleeve 32. Furthermore, the fastening ring rib 1165 of the coffee powder blower 10 is sleeved and pressed against the outer peripheral wall of the plastic cup sleeve 32, thus securely fastening the coffee powder blower 10 to the plastic cup sleeve 32 of the coffee powder cup structure 30 in this embodiment, thereby allowing the coffee powder to be extruded. The elastic capsule 11 of the blower 10 connects the lower air outlet 114 of the coffee powder blower 10 with the liquid outlet 313 of the stainless steel cup 31 of the powder cup structure 30. Specifically, when the user squeezes the elastic capsule 11 of the coffee powder blower 10, the first valve plate 1132 at the upper air inlet 112 of the coffee powder blower 10 abuts against the upper end wall of the elastic air chamber 111 under the compression of the air inside the elastic capsule 11, thus sealing the lower end of the upper air inlet 112. Simultaneously, the coffee powder blower 10... The second valve plate 1152 at the lower air outlet 114 moves away from the lower end of the lower air outlet 114 under the compression of the air in the elastic capsule 11, so that the air in the elastic capsule 11 is sent from the lower air outlet 114 to the liquid outlet 313 of the stainless steel cup 31 to be blown into the brewing chamber 312 of the stainless steel cup 31. Under the pushing action of the airflow, the coffee powder in the brewing chamber 312 of the stainless steel cup 31 can be quickly detached and poured out of the brewing chamber 312 of the stainless steel cup 31, and the coffee powder is blown off completely.

[0046] Third embodiment of coffee powder cup assembly: As an explanation of the third embodiment of the coffee powder cup assembly of this utility model, the following description only focuses on the differences from the first embodiment of the coffee powder cup assembly.

[0047] See Figure 11 In this embodiment, the coffee powder cup assembly includes a stainless steel powder cup 40 and a coffee powder puck blower 10. Specifically, the stainless steel powder cup 40 has a cavity opening 401 and a brewing cavity 402 connected to the cavity opening 401. The brewing cavity 402 is used to hold coffee powder, and the liquid outlet end 404 of the stainless steel powder cup 40, which is opposite to the cavity opening 401, has a liquid outlet hole 403 that is connected to the brewing cavity 402.

[0048] After coffee extraction is complete, the coffee puck, extracted by high-temperature and high-pressure water, adheres to the periphery of the brewing chamber 402 of the stainless steel coffee cup 40. The user then inverts the stainless steel coffee cup 40 so that the chamber opening 401 faces downwards. When the stainless steel coffee cup 40 is placed with its chamber opening 401 facing downwards, the liquid outlet 404 of the stainless steel coffee cup 40 is positioned upwards. The user then places the elastic ring 116 of the coffee puck blower 10 on the liquid outlet 404 of the stainless steel coffee cup 40, so that the lower end face of the elastic ring 116 of the coffee puck blower 10 presses against the liquid outlet 404 of the stainless steel coffee cup 40, thus firmly placing the coffee puck blower 10 on the liquid outlet 404 of the stainless steel coffee cup 40. This allows the elastic capsule 11 of the coffee puck blower 10 to be squeezed, causing the lower air outlet 114 of the coffee puck blower 10 to... The outlet 403 of the stainless steel powder cup 40 is connected.

In this embodiment, the liquid outlet end 604 of the stainless steel powder cup 60 is positioned such that the upper end surface of the second annular cavity 1162 of the coffee powder pouch blower 10 presses against the end face of the liquid outlet end 604 of the stainless steel powder cup 60 away from the cavity opening 601, and the support shoulder 1164 of the coffee powder pouch blower 10 is fitted and pressed against the outer peripheral wall of the stainless steel powder cup 60, so as to securely fasten the coffee powder pouch blower 10 to the liquid outlet end 604 of the stainless steel powder cup 60 in this embodiment, thereby allowing the elasticity of the coffee powder pouch blower 10 to be squeezed. The elastic capsule 11 connects the lower air outlet 114 of the coffee powder pouch blower 10 with the liquid outlet 603 of the stainless steel powder cup 60. Specifically, when the user squeezes the elastic capsule 11 of the coffee powder pouch blower 10, the first valve plate 1132 at the upper air inlet 112 of the coffee powder pouch blower 10 abuts against the upper cavity wall of the elastic air chamber 111 under the compression of the air inside the elastic capsule 11, thus sealing the lower end of the upper air inlet 112. At the same time, the lower air outlet 114 of the coffee powder pouch blower 10... The second valve plate 1152 moves away from the lower end of the lower air outlet 114 under the compression of the air inside the elastic capsule 11, so that the air inside the elastic capsule 11 is sent from the lower air outlet 114 to the liquid outlet 603 of the stainless steel powder cup 60 to be blown into the brewing chamber 602 of the stainless steel powder cup 60. Under the driving force of the airflow, the coffee powder cake in the brewing chamber 602 of the stainless steel powder cup 60 can be quickly detached and poured out of the brewing chamber 602 of the stainless steel powder cup 60, so that the coffee powder cake is blown off completely.
