Description

Technical Field

[0001] This invention relates to the field of beverage brewing equipment technology, and in particular to a capsule brewing machine. Background Technology

[0002] The beverage capsule brewing machine has been rapidly adopted in many countries and regions. It's a convenient beverage preparation device that allows users to quickly make various drinks, such as coffee and tea, using pre-filled capsules and a dedicated brewing machine. Due to its convenience, versatility, and sustainability, it has been widely used in many countries and regions since its introduction. In existing beverage capsule brewing machines, after the user places the capsule into the machine, hot water is injected into the capsule through a special nozzle. The hot water reacts with the ingredients inside the capsule, releasing the flavor and aroma of the beverage. The user can then adjust the hot water temperature and injection time using buttons on the brewing machine to achieve the optimal beverage taste.

[0003] While existing beverage capsule brewing machines offer many conveniences, they still have some problems. The most significant issue is that some water remains inside the capsule after brewing. This residual moisture keeps the tea leaves damp inside the capsule for an extended period, potentially damaging their flavor and aroma, thus affecting the color and taste of the tea. Furthermore, because this water cannot be quickly drained, it can also negatively impact the results of subsequent brews. Summary of the Invention

[0004] The purpose of this invention is to provide a capsule brewing machine that can expel residual water from the capsule by blowing air, preventing the tea from becoming stale and ensuring that the effect of the next brewing is not affected.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A capsule brewing machine includes a base, with a housing at the upper end of the base. The housing includes a water tank bottom shell, a main shell located on one side of the water tank bottom shell, and a brewing shell connected to the upper part of the main shell and located away from the water tank bottom shell. The base has a placement platform below the brewing shell. A water storage tank with an open top is detachably connected to the upper end of the water tank bottom shell. A lid is detachably connected to the upper end of the water storage tank. A water passage hole is opened at the bottom of the water storage tank. A water pipe that cooperates with the water passage hole is provided at the upper end of the water tank bottom shell.

[0007] The main housing is equipped with a water pump, a hot water tank, and a water flow diversion valve. One connection port of the water pump is connected to the lower end of the water pipe through a connecting pipe. The hot water tank is equipped with a spiral electric heating tube. The water flow diversion valve includes a water pump connecting pipe, a hot water lower connecting pipe, and a water pump connecting pipe connected in a Y-shape. The water pump connecting pipe is connected to the other connection port of the water pump. The hot water lower connecting pipe is connected to the hot water tank. The water pump connecting pipe is connected to a water pump pipe that extends outward from the main housing. The hot water lower connecting pipe is equipped with a first one-way valve that communicates with the hot water tank. The water pump connecting pipe is equipped with a second one-way valve that communicates with the water pump connecting pipe.

[0008] The brewing shell has a brewing groove with an open bottom on the side away from the water tank. Two opposing inner sides of the brewing groove are horizontally arranged with first slide rails. An electromagnet is installed at the upper end of the brewing groove inside the brewing shell. A through hole is opened downwards in the middle of the electromagnet. A perforation communicating with the through hole is opened at the top of the brewing groove. Multiple limiting shafts are arranged upwards on the upper edge of the electromagnet. An iron plate is movably arranged at the upper end of the electromagnet. The iron plate has multiple sliding holes that slide and connect one-to-one with the limiting shafts. A water injection pipe that mates with the through hole is arranged downwards at the lower end of the iron plate. The lower end of the water injection pipe is pointed. A supporting spring for the water injection pipe is arranged between the electromagnet and the iron plate.

[0009] The brewing shell is also equipped with a water-air diversion valve and an air pump. The water-air diversion valve includes a hot water upper connection pipe, a water injection connection pipe and an air blowing pipe connected in a Y-shape. The hot water upper connection pipe is connected to the end of the hot water tank away from the water diversion valve. The air blowing pipe is connected to the outlet end of the air pump. The water injection connection pipe is connected to the upper end of the water injection pipe. A third one-way valve is provided in the hot water upper connection pipe and communicates with the water injection connection pipe. A fourth one-way valve is provided in the air blowing pipe and communicates with the water injection connection pipe.

[0010] It also includes a plastic capsule cup holder, which includes a first end cap that matches the side opening of the brewing tank, a first horizontal cover that is vertically connected to the first end cap and slidably connected to the first slide rail, and a capsule cup slot disposed below the first horizontal cover and matching the shape of the plastic capsule. The upper end of the first horizontal cover has an inlet that matches the upper opening of the capsule cup slot, and the bottom of the capsule cup slot has a first water outlet that communicates with its interior.

[0011] By adopting the above technical solution, when using plastic capsules for brewing, first place the capsule in the plastic capsule cup holder, then place the plastic capsule cup holder into the brewing tank. When the electromagnet is energized, it generates magnetism to attract the iron plate, causing the water injection pipe to move down and pierce the top membrane of the plastic capsule. The water pump works to draw water from the water storage tank and inject it into the hot water tank through the water flow diversion valve for heating. After rapid heating, the water is injected into the water injection pipe through the water vapor diversion valve. The water injection pipe injects water into the capsule for brewing. Then, the tea flows out from the bottom of the plastic capsule and drips into the cup. After brewing, the water pump stops working, and the air pump works, blowing air into the capsule through the water flow diversion valve and the water injection pipe to expel the residual water inside the capsule.

[0012] A further feature of the present invention includes a metal capsule cup holder, the metal capsule cup holder comprising a second end cap that mates with the side opening of the brewing tank, a second horizontal cap that is perpendicularly connected to the second end cap and slidably connected to the first slide rail, and a placement cup sleeve disposed below the second horizontal cap. The second horizontal cap has a slot that mates with and communicates with the placement cup sleeve. The second horizontal cap and the placement cup sleeve have insertion notches located away from the second end cap, communicating with the slot and the interior of the placement cup sleeve. The bottom of the placement cup sleeve has a second water outlet communicating with its interior. The cup holder has multiple protrusions at its bottom. The upper end of the second horizontal cover is rotatably connected to a connecting strip that rotates toward the slot. The free end of the connecting strip has a pressure cap that matches the slot. The lower end of the pressure cap has a capsule cover that matches the shape of the bottom of the metal capsule. A water injection gap is provided between the pressure cap and the capsule cover. The upper end of the pressure cap has a water injection hole that communicates with the water injection gap and matches the water injection pipe. The bottom of the water injection gap is connected to multiple hollow needles that extend into the capsule cover.

[0013] A further feature of the present invention is that a support ring not higher than the protrusion is provided at the bottom edge of the cup holder.

[0014] A further feature of the present invention is that two cup holder placement slots are provided inwardly on the side wall of the main housing, and a second slide rail is provided horizontally inwardly on the two opposite inner sides of each cup holder placement slot, which is slidably connected to the first horizontal cover or the second horizontal cover.

[0015] A further feature of the present invention is that a rare earth thick film made of rare earth material is disposed on the outside of the spiral electric heating tube.

[0016] A further feature of the present invention is that: a plurality of inverted L-shaped baffles distributed in a circular pattern are provided at the bottom of the water storage tank at the edge of the water passage hole; a baffle for blocking the water passage hole is provided at the bottom of the water storage tank within the inverted L-shaped baffles; a pressure spring is provided between the baffle and the barb of the inverted L-shaped baffle; and a plurality of water flow notches are provided in the portion of the water pipe extending into the water storage tank.

[0017] A further feature of the present invention is that a rubber plug that mates with the water passage hole is provided at the lower end of the baffle.

[0018] A further provision of the present invention is that: a detection port is provided on one side of the water storage tank with the bottom facing upward; a laser ranging sensor that cooperates with the detection port is provided on the upper end of the bottom shell of the water tank; a water level groove is provided on the inner wall of the water storage tank above the detection port; and a water level float that cooperates with the laser ranging sensor is slidably connected in the water level groove.

[0019] A further feature of the present invention is that the lower end of the brewing shell is provided with a water collection channel that is inclined downward and away from the water storage tank, the water collection channel being wider at the top and narrower at the bottom, and the upper end of the water collection channel being connected to the lower end of the brewing tank.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] Firstly, the capsule brewing machine of the present invention has an air blowing function after brewing, which can expel the residual water in the capsule by blowing air, effectively preventing the tea from becoming stale and avoiding affecting the effect of brewing once;

[0022] Secondly, by replacing the plastic capsule holder with the metal capsule holder, the same brewing machine can brew both plastic and metal beverage capsules, achieving multi-purpose functionality.

[0023] Thirdly, the present invention, through the structural design of the water flow diversion valve, enables only one water pump to realize the functions of water injection and water filling to the water storage tank, saving equipment costs. Through the structural design of the water-air diversion valve, water injection and air blowing can be adaptively separated and do not interfere with each other.

[0024] Fourth, this invention automatically detects the water level in the water tank by combining a laser rangefinder sensor with a water level float, which can accurately determine the amount of water in the water tank, making it easy to judge the amount of water used for brewing based on changes in water volume, and automatically pump water to replenish water when the water level is low.

[0025] Fifth, the present invention has a rare earth thick film on the outside of the spiral electric heating tube. Rare earth materials have high thermal conductivity and heat capacity, so they can quickly transfer heat to the heated object, thereby achieving the effect of rapid heating. When you want to drink water, the water will be heated instantly when it passes through the boiling heating tube and then the water will come out, thus achieving the effect of water coming out in three seconds.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0037] Example, refer to Figure 1-8 A capsule brewing machine includes a base 1, with a housing at the upper end of the base 1. The housing includes a water tank bottom shell 21, a main shell 22 located on one side of the water tank bottom shell 21, and a brewing shell 23 connected to the upper part of the main shell 22 and located away from the water tank bottom shell 21. A placement platform 11 is provided below the brewing shell 23 on the base 1. A transparent water storage tank 3 with an open top is detachably connected to the upper end of the water tank bottom shell 21, and a lid 31 is detachably connected to the upper end of the water storage tank 3.

[0038] A water passage hole 32 is provided at the bottom of the water tank 3. Multiple inverted L-shaped baffles 33 are arranged circumferentially around the edge of the water passage hole 32 at the bottom of the water tank 3. A baffle plate 34 is installed inside the inverted L-shaped baffles 33 at the bottom of the water tank 3 to block the water passage hole 32. A rubber plug 35 that mates with the water passage hole 32 is provided at the lower end of the baffle plate 34. A downward pressure spring 36 is installed between the baffle plate 34 and the barb of the inverted L-shaped baffle 33. A water pipe 24 that mates with the water passage hole 32 is provided at the upper end of the water tank bottom shell 21. The portion of the water pipe 24 that extends into the water tank 3 has four water flow notches 25. When the water tank 3 is placed on the water tank bottom shell 21, the water pipe 24 is inserted into the water passage hole 32, pushing the rubber plug 35 and the baffle plate 34 upwards, allowing water to flow into the water tank 3 through the water flow notches 25, thus connecting the water tank 3 with the water pipe 24.

[0039] A detection port 37 is located on one side of the water tank 3, facing upwards from the bottom. A laser rangefinder sensor 4, which works in conjunction with the detection port 37, is located on the upper end of the bottom shell 21 of the water tank. A water level groove 38 is provided on the inner wall of the water tank 3 above the detection port 37. A water level float 39, which works in conjunction with the laser rangefinder sensor 4, is slidably connected within the water level groove 38. The water level float 39 floats on the water surface. The laser rangefinder sensor 4 emits a laser beam that passes through the water tank 3 and the water inside, illuminating the float 39, which then floats back to the surface. The position of the float 39 is measured to determine the water level in the water tank 3.

[0040] The main housing 22 is equipped with a water pump 5, a hot water tank 6 and a water flow diversion valve 7. One of the connection ports of the water pump 5 is connected to the lower end of the water pipe 24 through a connecting pipe 51. The hot water tank 6 is equipped with a spiral electric heating tube 61. The spiral electric heating tube 61 is covered with a rare earth thick film made of rare earth material. Rare earth material has high thermal conductivity and heat capacity, so it can quickly transfer heat to the object being heated, thereby achieving the effect of rapid heating. The water flow diversion valve 7 includes a water pump connecting pipe 71, a hot water lower connecting pipe 72, and a water pump connecting pipe 73 connected in a Y-shape. The water pump connecting pipe 71 is connected to another connection port of the water pump 5. The hot water lower connecting pipe 72 is connected to the hot water tank 6. The water pump connecting pipe 73 is connected to a water pumping pipe 74 that extends outward from the main housing 22. A first one-way valve 75 is installed in the hot water lower connecting pipe 72, which is connected to the hot water tank 6. A second one-way valve 76 is installed in the water pump connecting pipe 73, which is connected to the water pump connecting pipe 71. Both the first one-way valve 75 and the second one-way valve 76 are composed of four connected, approximately conical, blades. When the water pump 5 rotates forward, the pressure generated can only push the first one-way valve 75 to open. At this time, the water pump 5 draws water from the water storage tank 3 and injects it into the hot water tank 6 after passing through the water flow diversion valve 7. When the water pump 5 rotates in reverse, the negative pressure generated can only drive the second one-way valve 76 to open. At this time, the water pump 5 injects water into the water storage tank 3 through the water pumping pipe 74.

[0041] A brewing tank 26 with an open bottom is provided on the side of the brewing shell 23 away from the water storage tank 3. A first slide rail 27 is provided horizontally inward on both opposite inner sides of the brewing tank 26. An electromagnet 8 is installed at the upper end of the brewing tank 26 inside the brewing shell 23. A through hole (not shown) is opened downward in the middle of the electromagnet 8. A through hole (not shown) is opened at the top of the brewing tank 26 and communicates with the through hole. Four limiting shafts 81 are provided upward on the upper edge of the electromagnet 8. An iron plate 82 is movably installed at the upper end of the electromagnet 8. The iron plate 82 has four sliding holes that are slidably connected to the limiting shafts 81 one by one (not shown). A water injection pipe 83 that cooperates with the through hole is provided downward at the lower end of the iron plate 82. The lower end of the water injection pipe 83 is pointed. A support spring 84 for the water injection pipe 83 is provided between the electromagnet 8 and the iron plate 82.

[0042] The brewing housing 23 also houses a water-air diversion valve 9 and an air pump 10. The water-air diversion valve 9 includes a hot water upper connection pipe 91, a water injection connection pipe 92, and an air blowing pipe 93 connected in a Y-shape. The hot water upper connection pipe 91 is connected to the end of the hot water tank 6 away from the water diversion valve 7. The water injection connection pipe 92 is connected to the upper end of the water injection pipe 83. The air blowing pipe 93 is connected to the outlet end of the air pump 10. The hot water upper connection pipe 91 is provided with a nozzle facing the water injection connection pipe 93. The third check valve 94 is connected to the air pipe 93, and the fourth check valve 95 is installed inside the air pipe 93 and is connected to the water injection pipe 92. Both the third check valve 94 and the fourth check valve 95 are composed of four connected approximately conical blades. When the water pump 5 rotates to inject water, the pressure generated pushes the third check valve 94, and water is injected from the hot water tank 6 into the water injection pipe 83. When the air pump 10 works, the pressure generated pushes the fourth check valve 95, and the air pump 10 blows air into the water injection pipe 83.

[0043] It also includes a plastic capsule cup holder, which includes a first end cap 111 that matches the side opening of the brewing tank 26, a first horizontal cap 112 that is vertically connected to the first end cap 111 and slidably connected to the first slide rail 27, and a capsule cup slot 113 that is disposed below the first horizontal cap 112 and matches the shape of the plastic capsule. The upper end of the first horizontal cap 112 has an inlet 114 that matches the upper opening of the capsule cup slot 113, and the bottom of the capsule cup slot 113 has a first water outlet 115 that communicates with the interior.

[0044] It also includes a metal capsule cup holder, which includes a second end cap 121 that matches the side opening of the brewing tank 26, a second horizontal cap 122 that is vertically connected to the second end cap 121 and slidably connected to the first slide rail 27, and a cup holder 123 disposed below the second horizontal cap 122. The second horizontal cap 122 has a slot 124 that matches and communicates with the cup holder 123. The second horizontal cap 122 and the cup holder 123 have an insertion notch 125 that communicates with the slot 124 and the interior of the cup holder 123 at a distance away from the second end cap 121. The bottom of the cup holder 123 has a second water outlet 126 that communicates with its interior. The bottom of the cup holder 123 is provided with multiple protrusions 127. The edge of the bottom of the cup holder 123 is provided with a support ring 128 that is no higher than the protrusions 127, so that after the top membrane of the capsule is punctured, there is still a gap between the top membrane and the bottom of the cup holder 123, which facilitates water discharge. The upper end of the second horizontal cover 122 is rotatably connected to a connecting strip 130 that rotates toward the slot 124 near the second end cover 121. The free end of the connecting strip 130 is provided with a pressure cap 131 that matches the slot 124. The lower end of the pressure cap 131 is provided with a capsule cover 132 that matches the shape of the bottom of the metal capsule. A water injection gap 133 is provided between the pressure cap 131 and the capsule cover 132. The upper end of the pressure cap 131 is provided with a water injection hole 134 that communicates with the water injection gap 133 and matches the water injection pipe 83. The bottom of the water injection gap 133 is connected to three hollow piercing needles 135 that extend into the capsule cover 132. After the capsule cover 132 is closed, the bottom of the metal capsule is pierced by the hollow piercing needles 135.

[0045] The main housing 22 has two cup holder slots 28 on its side wall, which are used to store plastic capsule cup holders and metal capsule cup holders. Each cup holder slot 28 has a second slide rail 29 horizontally arranged on its two opposite inner sides, which slides inward to cooperate with the first horizontal cover 112 or the second horizontal cover 122. The lower end of the brewing housing 23 has a downward-sloping water collection channel 140 that is wider at the top and narrower at the bottom. The upper end of the water collection channel 140 connects to the lower end of the brewing tank 26, allowing the flowing tea to collect and flow out from a small opening, making the water flow more concentrated and preventing dripping outside the cup due to uneven water flow, especially when blowing air to drain the water.

[0046] Working principle: When using plastic capsules for brewing, first place the capsule in the plastic capsule cup holder, then place the plastic capsule cup holder into the brewing tank 26. When the electromagnet 8 is energized, it generates magnetism to attract the iron plate 82, causing the water injection pipe 83 to move down and pierce the top membrane of the plastic capsule. The water pump 5 works to draw water from the water storage tank 3 and inject it into the hot water tank 6 through the water flow diversion valve 7 for heating. After rapid heating, the water is injected into the water injection pipe 83 through the water vapor diversion valve 9. The water injection pipe 83 injects water into the capsule for brewing. Then, the tea flows out from the bottom of the plastic capsule and drips into the cup. After brewing, the water pump 5 stops working, and the air pump 10 works to blow air into the capsule through the water flow diversion valve 7 and the water injection pipe 83 to expel the water remaining in the capsule.

[0047] When using a metal capsule for brewing, place the metal capsule upside down inside the cup sleeve 123 and cover it with the capsule cover 132. The hollow needle 135 punctures the bottom of the metal capsule. After the electromagnet 8 is energized, it pushes the water injection tube 83 into the water injection hole 134. After repeating the above water boiling steps, water is injected into the water injection gap 133. Hot water is then poured into the capsule through the hollow needle 135 for brewing. After brewing, the above blowing steps are repeated to expel the water remaining in the capsule.

[0048] When the water level float 39 drops to a certain position, the laser range sensor 4 detects and determines that the water storage tank 3 is short of water. The water pump 5 reverses, causing the negative pressure generated in the water diversion valve 7, which drives the second one-way valve 76 to open. At this time, the water pump 5 injects water into the water storage tank 3 through the water pumping pipe 74.

[0049] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
