Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a bursting structure for a beverage extraction device, as well as the extraction device and a portable coffee machine. Background Technology

[0002] A coffee machine is a device used to make coffee. It generally has an extraction unit that uses a liquid bursting mechanism to dispense the coffee. Specifically, it consists of inner and outer cups and a bursting plate inside the outer cup, with several protrusions on the bursting plate. When liquid is poured into the extraction unit, the water pressure causes the needle in the inner cup to pierce the rear end of the capsule. At the same time, the protrusions on the bursting plate press against the aluminum foil on the front end of the capsule. Simultaneously, the piercing allows high-pressure hot water to enter the capsule, causing it to inflate under water pressure. The aluminum foil is then burst by the protrusions on the bursting plate, and the beverage flows out through the outlet channel on the bursting plate, completing the extraction process.

[0003] The existing protrusions are generally arranged in a regular matrix to form a uniformly distributed grid, and the height of the protrusions is basically the same. As the capsule bulges under water pressure to form an arc shape that bulges outward from the center, only the few rows of protrusions in the middle will have a bursting effect, while the other protrusions on the outside will not have a bursting effect. Or the protrusions on the outside can have a bursting effect, but only the end of the protrusion can extend into the aluminum foil, resulting in a poor bursting effect, so it cannot completely break the aluminum foil. Summary of the Invention

[0004] The purpose of this invention is to provide a bursting structure for a beverage extraction device, as well as an extraction device and a portable coffee machine. By setting the height of the protrusion in the center of the bursting area to be lower than the height of the protrusions near the outer periphery (i.e., lower in the center and higher on the periphery), it can better fit the outer surface of the capsule that bulges under water pressure, thereby ensuring that most of the protrusions can play a bursting role, resulting in a better bursting effect and better ability to break the aluminum foil. Thus, it solves the problem that the existing outer protrusions do not play a bursting role or have a poor bursting effect.

[0005] The purpose of this utility model is achieved as follows:

[0006] The bursting structure for a beverage extraction device includes a base plate, and the upper surface of the base plate is divided into a puncture area and a peripheral area. The puncture area is provided with a number of protrusions and a number of channels for liquid flow, and the height of the protrusions located in the center of the puncture area is lower than the height of the protrusions near the peripheral area.

[0007] Preferably, among the plurality of protrusions, there is a protrusion with a sloping top, and the height of the sloping surface of the protrusion near the center of the puncture area is lower than the height of the protrusion away from the center of the puncture area.

[0008] Preferably, the plurality of protrusions also includes a protrusion with a flat top, and the protrusion with a flat top is located at the center of the puncture area, and the protrusion with a sloping top is located outside the protrusion with a flat top.

[0009] Or / and, the tilt angle of the protrusion one near the center of the puncture area is smaller than the tilt angle of the protrusion one far from the center of the puncture area;

[0010] Or / and, the tilt angle of the top of the protrusion is 4°-6°.

[0011] Preferably, the protrusion includes a base and a puncture part disposed on the base, and the base is a frustum or a rectangular frustum;

[0012] Or / and, the protrusion includes a base and a puncture portion disposed on the base, wherein the puncture portion is a frustum or a cuboid.

[0013] Preferably, the plurality of protrusions are configured as multiple rings arranged from the inside out;

[0014] Alternatively, the upper surface of the puncture area is divided into an upper part, a middle part, and a lower part, and each part is provided with a protrusion. The protrusions in the upper part, the middle part, and the lower part are divided into multiple rows, and each row is a straight line. The two adjacent rows in the upper part are staggered, and the two adjacent rows in the lower part are staggered.

[0015] Alternatively, the plurality of protrusions may be divided into multiple rows and columns, with each row and column being a straight line.

[0016] Preferably, the distance between two adjacent protrusions is 3mm-5mm, and the distance between protrusions located in the center of the puncture area is greater than or equal to the distance between protrusions near the outer periphery.

[0017] Or / and, the height difference between the protrusion located at the center of the puncture area and the protrusion near the outer perimeter is 0.3mm-0.6mm.

[0018] Preferably, the puncture area is provided with a boss, and the boss is provided with a plurality of protrusions and a plurality of channels for liquid flow, and a sealing ring is fitted on the outside of the boss;

[0019] Or / and, the bottom ends of the base plate are formed with bevels or rounded corners.

[0020] An extraction device includes an outer cup and an inner cup, with the inner cup disposed inside the outer cup. The inner cup contains a needle, and the outer cup has the aforementioned base plate disposed below the inner cup.

[0021] Preferably, the inner wall of the outer cup is provided with a limiting block, and the upper surface of the limiting block is wavy, and a limiting groove is opened on the outer side of the inner cup corresponding to the limiting block.

[0022] A portable coffee machine includes a cup body, and an extraction device is provided inside the cup body. The extraction device includes an outer cup and an inner cup, wherein the inner cup is disposed inside the outer cup, and the base plate is provided below the inner cup on the outer cup.

[0023] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0024] 1. This utility model has a design where the height of the protrusion located in the center of the puncture area is lower than the height of the protrusions near the outer periphery, i.e., the center is lower and the periphery is higher. This design allows the protrusions to fit more closely to the outer surface of the capsule when it bulges under water pressure, thereby ensuring that most of the protrusions can play their role in bursting, resulting in a better bursting effect and better ability to break the aluminum foil.

[0025] 2. The preferred embodiment of this utility model is that by setting the top slope of the protrusion, it can fit more closely with the outer surface of the capsule that bulges under water pressure. At the same time, it can make the higher side of the protrusion puncture the aluminum foil layer first, guiding the entire protrusion to extend into the aluminum foil layer in an inclined state. This makes the integrity of the broken part of the aluminum foil layer better, reduces the possibility of aluminum foil layer producing debris, and thus reduces the possibility of debris affecting the quality of coffee liquid.

[0026] 3. The preferred embodiment of this utility model is to increase the total number of protrusions by arranging and combining them in different ways, so as to make more holes puncture the aluminum foil layer of the capsule, thereby accelerating the rate of synchronous liquid discharge.

[0066] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0067] like Figures 1-6 As shown, the bursting structure for a beverage extraction device includes a base plate 1, and the upper surface of the base plate 1 is divided into a puncture area and an outer area. The puncture area is provided with a number of protrusions 11 and a number of channels 12 for liquid flow. The height of the protrusions 11 located in the center of the puncture area is lower than the height of the protrusions 11 near the outer area.

[0068] Therefore, in actual use, by setting the height of the protrusion 11 located in the center of the puncture area to be lower than the height of the protrusion 11 near the outer periphery, that is, setting the center low and the periphery high, it can fit more closely with the outer surface of the capsule that bulges under water pressure, thereby ensuring that most of the protrusions 11 can play the role of bursting, thus making the bursting effect better and being able to break the aluminum foil better.

[0069] It should be noted that, as mentioned above, the number A of the protrusions 11 located in the center of the puncture area is not limited and can be set to one or more.

[0070] Secondly, the top of the protrusion 11 is generally flat. However, in order to fit more closely with the outer surface of the capsule that bulges under water pressure, some of the aforementioned protrusions 11 have a sloping top. Furthermore, the height of the sloping side of the protrusion 11 near the center of the puncture area is lower than the height of the side away from the center of the puncture area. In other words, the sloping side faces towards the center of the puncture area.

[0071] Furthermore, given the height difference of the protrusions 11, setting the top of protrusion 11 as a slope allows the higher side of protrusion 11 to pierce the aluminum foil layer first. This guides the entire protrusion 11 into the aluminum foil layer at an angle, resulting in better integrity of the broken portion of the aluminum foil layer and reducing the possibility of aluminum foil debris, thus minimizing the possibility of debris affecting the quality of the coffee liquid. The slope angle of the top of protrusion 11 is 4°-6°, and this slope angle is the angle between the horizontal plane and the slope of the top of protrusion 11.

[0072] Meanwhile, in actual use, the outer surface of the capsule bulges under water pressure, with the middle part tending to be flat and the two sides tending to be curved. Therefore, among the several protrusions 11, there is also a protrusion 11 with a flat top. The protrusion 11 with a flat top is located in the center of the puncture area, and the protrusion 11 with a sloping top is located on the outside of the protrusion 11 with a flat top, thus fitting more closely with the outer surface of the capsule bulging under water pressure.

[0073] It should be noted that there is no limit to the number B of the sloping protrusions 11, and the number of B at this point does not interfere with the number of A mentioned above.

[0074] Furthermore, the tilt angle of the sloping protrusions 11 can be set to be consistent, or the tilt angle of the protrusions 11 closer to the center of the puncture area can be smaller than the tilt angle of the protrusions 11 farther from the center of the puncture area, so that the top height of the protrusions 11 on the outer side is higher than the top height of the protrusions 11 in the center, and the protrusions 11 with different slopes can also be made to fit against the outer surface of the capsule that bulges under water pressure.

[0075] Next, examples will be given to illustrate the above. Figure 4 In the puncture zone, the top of one protrusion 11 located at the center of the puncture zone is flat and has the lowest height. Apart from that, the tops of the other protrusions 11 are all sloping, with the same angle of inclination. Furthermore, the maximum height of the protrusions 11 gradually increases along the direction closer to the outer perimeter, making this puncture structure exhibit the aforementioned "low center, high perimeter" characteristic.

[0076] Furthermore, different specifications of base plates 1 can be obtained by simply changing the height difference of protrusion 11, or by modifying only the tilt angle of the top of protrusion 11 based on the height difference of protrusion 11, or by modifying both the height difference of protrusion 11 and the tilt angle of the top of protrusion 11 simultaneously.

[0077] Meanwhile, the upper surface of the puncture area is generally flat, so the height difference of the protrusion 11 depends only on the protrusion 11 itself. However, if a larger height difference is required, the upper surface of the puncture area can be set as a concave surface to increase the height difference and make the outer surface of the capsule bulge more closely under water pressure.

[0078] Furthermore, the slope of protrusion 11 can be straight or curved, meaning it can be slightly concave inward.

[0079] In addition, such as Figures 1-6 As shown, the protrusion 11 includes a base 111 and a puncture part 112 disposed on the base 111, wherein the base 111 is a frustum or a rectangular frustum, and the puncture part 112 is a frustum or a rectangular frustum.

[0080] Therefore, in practical use, various combinations can be made, such as... Figure 1 As shown, the base 111 is a frustum of a cone, and the puncture part 112 is a rectangular frustum; or as... Figure 5 As shown, the base 111 is a frustum, and the puncture part 112 is also a frustum; or as... Figure 6 As shown, the base 111 is a rectangular platform, and the puncture part 112 is also a rectangular platform.

[0081] Furthermore, the base 111 and the puncture part 112 can also be polygonal truncated structures, such as hexagonal truncated structures or octagonal truncated structures.

[0082] like Figures 1-6 As shown, based on the height difference between protrusions 11 or on the height difference between protrusions 11 with the top being a slope, several protrusions 11 can also be arranged in different combinations, such as concentric circles, staggered or matrix settings, and by different arrangements, the total number of protrusions can be increased, so that more holes are punctured in the aluminum foil layer of the capsule, thereby accelerating the rate of synchronous liquid discharge.

[0083] When it is set as concentric circles, such as Figure 1 As shown, several protrusions 11 are arranged in a multi-ring configuration from the inside out. The specific number of rings can be selected according to actual needs. They can be divided into one ring, two rings, and three rings, forming a three-ring configuration. A protrusion 11 can also be provided in the center of the one ring.

[0084] Secondly, when it is a misaligned setting, such as Figure 5 As shown, the upper surface of the puncture area is divided into an upper part, a middle part, and a lower part, and each part is provided with a protrusion 11. The protrusions 11 in the upper part, the middle part, and the lower part are divided into multiple rows, and each row is a straight line. The two adjacent rows in the upper part are staggered, and the two adjacent rows in the lower part are staggered.

[0085] Furthermore, the two adjacent rows at the top and middle are also staggered, as are the two adjacent rows at the bottom and middle.

[0086] At the same time, when it is set as a matrix, such as Figure 6 As shown, several protrusions are divided into multiple rows and columns, and each row and column is a straight line.

[0087] like Figures 1-6As shown, the detailed structure of protrusion 11 is as follows: First, the distance between two adjacent protrusions 11 is 3mm-5mm, and the distance between protrusions located in the center of the puncture area is greater than or equal to the distance between protrusions near the outer perimeter. When the distance between protrusions in the center of the puncture area is greater than the distance between protrusions near the outer perimeter, the density increases from the center to the perimeter, thus increasing the number of protrusions 11, resulting in a better bursting effect and better ability to break the aluminum foil.

[0088] Furthermore, the height difference between the protrusion 11 located in the center of the puncture area and the protrusion 11 near the outer perimeter is 0.3mm-0.6mm.

[0089] like Figure 6 As shown, the structure of the base plate 1 can be further optimized as follows: First, a boss 13 is provided in the puncture area, and several protrusions 11 and several channels 12 for liquid flow are provided on the boss 13, and a sealing ring is sleeved on the outside of the boss 13.

[0090] Therefore, in actual use, by setting the sealing ring, when the outer surface of the capsule is attached to the boss 13, the edge of the capsule can be held in place by the sealing ring to prevent liquid leakage during the extraction process. Moreover, the top surface of the sealing ring can be set to be slightly higher than the surface of the boss 13.

[0091] Meanwhile, the bottom ends of the base plate 1 are formed with bevels or rounded corners to avoid contact with other components and cause interference.

[0092] This invention also protects the extraction device, such as... Figures 7-9 As shown, it includes an outer cup 21 and an inner cup 22, with the inner cup 22 disposed inside the outer cup 21. The inner cup 22 contains a needle 23, and the outer cup 21 has a base plate 1 as described above below the inner cup 22.

[0093] Meanwhile, a limiting block 211 is provided on the inner wall of the outer cup 21, and the upper surface of the limiting block 211 is wavy, and a limiting groove 221 is opened on the outer side of the inner cup 22 corresponding to the limiting block 211.

[0094] Therefore, in actual use, the mutual rotation between the outer cup 21 and the inner cup 22 is restricted by the matching of the limiting block 211 and the limiting groove 221.

[0095] Furthermore, this utility model also protects a portable coffee machine, which includes a cup body 3, and an extraction device is provided inside the cup body 3. The extraction device includes an outer cup 21 and an inner cup 22. The inner cup 22 is disposed inside the outer cup 21, and the outer cup 21 is provided with a base plate 1 as described above below the inner cup 22.

[0096] like Figures 10-20 As shown, the other structural features of the portable coffee machine are:

[0097] Firstly, portable coffee machines have an anti-tipping function, and there are different implementation methods to achieve this anti-tipping function.

[0098] Example 1: As Figures 10-12 As shown, the device includes a cup body 3, with a cup lid 4 and an outer cup body 5 at each end. Normally, a portable coffee machine can be placed using the outer cup body 5. However, in some cases, the portable coffee machine cannot be placed using the outer cup body 5. Therefore, the cup lid 4 in this invention has at least one support area on the side away from the cup body 3, and this support area can fit against the placement surface to keep the cup body 3 upright and prevent it from tilting.

[0099] Therefore, in actual use, the lid 4 has at least one support area on the side away from the cup body 3. The support area can fit against the placement surface to keep the cup body 3 upright and prevent it from tilting. Thus, it can be inverted. So, in addition to relying on the outer cup body 5 to place the entire portable coffee machine, it can also rely on the support area for placement. Moreover, when removing the outer cup body 5 and / or the outer cup 21 from the cup body, the support area can also fit against the placement surface to prevent the cup body 3 from tilting, thereby also preventing the coffee machine from contacting the table surface with the extraction device or the part connecting the outer cup body 5.

[0100] The placement surface is the surface on which the coffee machine is placed, such as on a table. The support area is the bottom surface of the lid 4, and the bottom surface of the lid 4 is flat.

[0101] Alternatively, the lid 4 may have a groove 436 on the side away from the body 3, and the support area may be a ring, with the ring being flat. A vent 46 may be provided within the groove 436 to facilitate ventilation. This is because when the cup is inverted, the side of the lid 4 away from the body 3 is completely flush with the tabletop, hindering ventilation; the groove 436 facilitates ventilation. Of course, a vent 46 may be provided instead of a groove 436.

[0102] Secondly, the cup body 3 is fitted onto one end of the cup lid 4 and is provided with a silicone part 3 48, and the outer cup body 5 is fitted onto the other end of the cup body 3 and is provided with a silicone part 4 311. Moreover, a silicone sleeve 45 can be provided on the outside of the cup lid 4 to play a non-slip role. The specific structure is as follows: the cup lid 4 includes an outer shell 43 and an inner shell 42 provided on the outer shell 43, and the cup body 3 is fitted onto the outside of the inner shell 42 with a silicone part 3 48 provided between the two. At the same time, a connector 31 is provided at the other end of the cup body 3, and the outer cup body 5 is fitted onto the outside of the connector 31 with a silicone part 4 311 provided between the two.

[0103] Example 2: This example is basically the same as Example 1, except that: Figures 17-20As shown, the cup lid 4 can also be used with the outer cup 21 and / or the connector 31. The specific structure is as follows: First, the cup body 3 is provided with a connector 31 at the end away from the cup lid 4, and the outer cup body 5 is sleeved on the outside of the connector 31, and the outer cup 21 is provided on the connector 31.

[0104] The part where the cup lid 4 connects to the cup body 3 is the connecting part 421, and the connector 31 can be sleeved on the outside of the connecting part 421 to place the cup body 3 on the cup lid 4.

[0105] Furthermore, the cup lid 4 has a silicone part 47 on the side near the cup body 3, and the top of the silicone part 47 has a mounting part 471. The outer cup 21 can be fitted onto the outside of the mounting part 471 so that the outer cup 21 can be placed on the cup lid 4.

[0106] Therefore, in actual use, when the outer cup body 5 is removed, the outer cup 21 can be fitted with the cup lid 4 so that the cup body 3 is placed upright on the cup lid 4. Moreover, when the outer cup body 5 and the outer cup 21 are removed, the connector 31 can be fitted with the cup lid 4 so that the cup body 3 is placed upright on the cup lid 4. At this time, since the support area can fit with the placement surface, the cup body 3 is placed vertically, so there is no need to tilt it and the coffee machine and the extraction component or the part connected to the outer cup body are not in contact with the table.

[0107] like Figure 18 As shown, the structure between the connector 31 and the cup lid 4 is as follows: First, the bottom of the connector 31 is provided with a storage groove 312, and the inner wall of the storage groove 312 is connected to the outer cup 21, and the opening of the storage groove 312 is sleeved on the outside of the connector 421.

[0108] Meanwhile, the inner shell 42 of the cup lid 4 is provided with a connecting part 421, and an installation groove 422 is provided on the outside of the connecting part 421. A silicone part 3 48 is built into the installation groove 422, and the outside of the silicone part 3 48 abuts against the inner wall of the connecting part 31, that is, abuts against the inner wall of the storage groove 312, so that the connection is more stable.

[0109] like Figure 20 As shown, the structure between the outer cup 21 and the cup lid 4 is as follows: First, an annular plate 24 is provided at the bottom of the outer cup 21, and the annular plate 24 is sleeved on the outside of the mounting part 471.

[0110] Meanwhile, the inner shell 42 of the cup lid 4 has an assembly groove 423 on the side near the cup body 3, and the silicone part 47 has an assembly part 472 corresponding to the assembly groove 423. The installation of the silicone part 47 is achieved by the matching of the assembly part 472 and the assembly groove 423.

[0111] like Figures 17-20As shown, other structural details are as follows: First, this utility model also includes a spare lid. When the cup body 3 is placed on the cup lid 4, the spare lid can be placed on top of the cup body 3, thereby preventing the top of the cup body 3 from coming into contact with the outside world and becoming contaminated. The spare lid has the same structure as the cup lid 4.

[0112] Meanwhile, the structure between the connector 31 and the outer cup 5 is as follows: First, a silicone part 311 is provided on the outside of the connector 31, and a protrusion is provided on the outside of the silicone part 311, and the protrusion abuts against the inner wall of the outer cup 5.

[0113] Furthermore, the outer cup 21 and the connector 31 are connected by threads, and the connector 31 and the cup body 3 can be connected by plugging or snapping.

[0114] Example 3: This example is basically the same as Example 1, except that the support area is different. The support area is a second protrusion 41, and the bottom surface of the second protrusion 41 is a plane. The second protrusion 41 can also be used to increase friction, thereby making the placement more stable.

[0115] The types and structures of the protrusions 41 are diverse. They can be simply provided at the bottom of the cup lid 4, or as shown in Embodiments 4 and 5.

[0116] Furthermore, protrusion 2 41 can exist alone or simultaneously with other support areas, such as protrusion 2 41 and the bottom surface of cup lid 4 being flat.

[0117] Example 4: This example is basically the same as Example 1, except that the support area is a second protrusion 41, the bottom surface of the second protrusion 41 is a plane, and the second protrusion 41 can also be used to increase friction, thereby making the placement more stable.

[0118] Furthermore, the number of protrusions 41 can be set according to actual needs, and three can be selected. The specific structure of protrusions 41 is as follows: Figures 13-14 As shown, the cup lid 4 includes an outer shell 43 and an inner shell 42 disposed on the outer shell 43, and the inner shell 42 is connected to the cup body 3. A silicone sleeve 45 is fitted on the outer side of the outer shell 43, and the silicone sleeve 45 has a protrusion 41 at the end away from the cup body 3.

[0119] Furthermore, the silicone sleeve 45 can play a non-slip role when holding the cup lid 4, and its installation structure is as follows: First, the upper and lower sides of the outer shell 43 are respectively provided with a first protrusion 434 and a second protrusion 435, and the upper end of the silicone sleeve 45 forms a hook part 451, which hooks the outside of the first protrusion 434. Second, the lower end of the silicone sleeve 45 forms a second hook part 452, which hooks the first hook part 451 on the outside of the second protrusion 435.

[0120] Secondly, the outer shell 43 and the inner shell 42 are connected by screws. Corresponding to the arrangement of the outer shell 43 and the inner shell 42, the specific structure of the vent 46 is as follows: the outer shell 43 has a vent 46 on the side away from the cup body 3, so as to facilitate the gas discharge between the outer shell 43 and the inner shell 42. At the same time, the inner shell 42 has a hole corresponding to the vent 46 to facilitate the ventilation between the inside and outside.

[0121] Example 5: This example is basically the same as Example 1, except that the support area is protrusion 2 41, and the specific structure of protrusion 2 41 differs from that of Example 4. For example... Figures 15-16 As shown, the outer shell 43 has an opening 431 on the side away from the cup body 3, and a silicone part 44 is provided between the inner shell 42 and the outer shell 43. The silicone part 44 has a protrusion 41 on the side near the outer shell 43, and the protrusion 41 is exposed through the opening 431.

[0122] Furthermore, the silicone part 44 also serves to seal the connection between the inner shell 42 and the outer shell 43. Its installation structure is as follows: First, a connecting groove 432 is provided inside the outer shell 43, and a protrusion 433 is provided on the inner wall of the connecting groove 432. The silicone part 44 is located inside the connecting groove 432, and a slot 441 is provided on the outer side of the silicone part 44 corresponding to the protrusion 433.

[0123] In summary, when the lid 4 has at least one support area on the side away from the cup body 3, the support area can fit against the placement surface to keep the cup body 3 upright and prevent it from tilting. Therefore, the entire coffee machine can be inverted. Of course, when the outer cup body 5 and / or the outer cup 21 are removed, the rest of the machine can also be inverted.

[0124] When the cup lid 4 is used as a support area, it can also be used with the outer cup 21 and / or the connector 31. Besides being inverted, it can also be placed upright. That is, when the outer cup body 5 is removed, the outer cup 21 can be fitted with the cup lid 4 to place the cup body 3 upright on the cup lid 4. Similarly, when the outer cup body 5 and the outer cup 21 are removed, the connector 31 can be fitted with the cup lid 4 to place the cup body 3 upright on the cup lid 4. Furthermore, for greater stability, structures such as protrusions 41 can be provided.

[0125] like Figures 21-24 As shown, the other structural features of the portable coffee machine are:

[0126] Firstly, the portable coffee machine has a control panel, namely a main control board 7 and an operation panel 8. The control panel is located inside the cup body 3 and below the water tank 9, with the cup lid 4 on top of the water tank 9. The installation structure of the operation panel 8 is as follows: the portable coffee machine includes a mounting bracket 6, the main control board 7, and the operation panel 8. The main control board 7 is located on the top of the mounting bracket 6, and the mounting bracket 6 has a first insertion interface 61. The main control board 7 has a second insertion interface 71 corresponding to the first insertion interface 61.

[0127] Meanwhile, the main control board 7 has at least one welding groove 72 on both sides of the second plug-in interface 71, and the top of the operation board 8 passes through the first plug-in interface 61 and the second plug-in interface 71 in sequence and is exposed. A welding block 73 is provided between the welding groove 72 and the exposed side of the operation board 8, and the connection is achieved by welding.

[0128] Therefore, in actual use, the top of the operation board 8 passes through the main control board 7 and is exposed. The main control board 7 and the operation board 8 are connected by welding, so that the operation board 8 is placed on the main control board 7 and electrically connected. Thus, the electrical connection by welding is used instead of the electrical connection of the ribbon cable, so that the wired connection method is not used, thereby avoiding the possibility of the ribbon cable being squeezed or worn.

[0129] Meanwhile, the welding process is relatively convenient to operate, thus saving time, and the welding block occupies relatively little space, so it will not hinder the use of space in other parts of the main control board.

[0130] The soldering slot 72 is specifically a solder pad in the prior art, and the soldering in this example can be done using a soldering process. Furthermore, the number of soldering slots 72 can be selected according to the actual situation and is not specifically limited, i.e., it depends on the number of circuits required between the main control board 7 and the operation board 8, and then the number of soldering slots 72 on both sides is balanced and distributed. The number and layout of the soldering slots 72 used in this example can be seen from the attached diagram; that is, there can be seven soldering slots 72, with three on one side of connector 2 71 and four on the other side.

[0131] Moreover, the distance between any two adjacent welding slots 72 is the same, which facilitates the welding process and avoids safety issues.

[0132] Meanwhile, the welding block 73 is arched, with one end of the welding block 73 located inside the welding groove 72, and the other end of the welding block 73 connected to the exposed side of the operating plate 8.

[0133] Therefore, in actual use, the arched design avoids sharp parts, resulting in a smooth surface, stable connection, and an attractive appearance.

[0134] Secondly, as Figure 24As shown, the structure of the operation plate 8 is as follows: First, the operation plate 8 includes a plug-in part 81 and a mounting part 82, and the plug-in part 81 is located on the top of the mounting part 82. The top of the mounting part 82 is provided with abutment surfaces 84 on both sides of the plug-in part 81. When the plug-in part 81 passes through the plug-in interface 71 and is exposed, the abutment surface 84 abuts against the bottom of the mounting bracket 6, and a welding block 73 is provided between the welding groove 72 and the side of the plug-in part 81.

[0135] Therefore, in actual use, since the plug-in part 81 is located at the top of the mounting part 82, and the top of the mounting part 82 is provided with abutment surfaces 84 on both sides of the plug-in part 81, that is, the length of the plug-in part 81 is less than the length of the mounting part 82, so it is stepped, so it can cooperate with the mounting bracket 6, thereby ensuring that the position of the operation plate 8 is correct and that the relative position between the operation plate 8 and the main control board 7 is correct, thus facilitating accurate welding.

[0136] At the same time, such as Figures 21-24 As shown, the control panel 8 is a long strip, and welding only corresponds to the installation of one end. Therefore, in order to make the control panel 8 installed stably, a connection structure, such as a snap-fit ​​or fastener connection, is provided between the control panel 8 and the mounting bracket 6.

[0137] When it is a snap-fit, the specific structure is as follows: First, the bottom of the mounting bracket 6 is provided with a mounting plate 62 on one side of the insertion interface 61, and the mounting plate 62 is provided with a buckle 63 on the side close to the insertion interface 61, and the operation plate 8 is provided with a corresponding snap-fit ​​interface 83.

[0138] Therefore, in actual use, the connection between the operation panel 8 and the mounting bracket 6 is achieved by the matching of the buckle 63 and the card interface 83.

[0139] When the fastener connection is used, the mounting plate 62 and the operating plate 8 are connected by fasteners, and the fasteners can be screws. Specifically, the operating plate 8 has a hole, the mounting plate 62 has a slot, and one end of the fastener passes through the operating plate 8 and is threaded to the mounting plate 62 to achieve the connection.

[0140] like Figures 21-22 As shown, the structure between the main control board 7 and the mounting bracket 6 is as follows: First, a mounting hole 1 is opened in the middle of the main control board 7, and a mounting hole 2 is opened in the mounting bracket 6 corresponding to the mounting hole 1. The main control board 7 is mounted on the mounting bracket 6 by passing one end of a fastener through the mounting hole 1 and threading it into the mounting hole 2. The fastener can be a screw.

[0141] like Figures 21-23 As shown, other detailed structures of the mounting bracket 6 are as follows: First, the bottom of the mounting bracket 6 is provided with a mounting rod 64 for mounting the mounting bracket 6 on the cup body, and a support plate 65 is provided on the outside of the mounting rod 64 to provide support and increase strength.

[0142] Meanwhile, a protrusion 66 is provided on the outer side of the mounting bracket 6, and the protrusion 66 can be adapted to the groove on the cup body to restrict the rotation of the mounting bracket 6.

[0143] like Figures 25-30 As shown, the other structural features of the portable coffee machine are:

[0144] Firstly, the portable coffee machine has a water tank 9, which is located at the opening at the top of the cup body 3. The water tank structure is as follows: the portable coffee machine includes a water tank 9, and a water outlet is provided on the bottom surface of the inner wall of the water tank 9. The height of the connection between the side and bottom surface of the inner wall of the water tank 9 is higher than the height of the water outlet, and the water outlet is provided with a water pipe 91.

[0145] Therefore, in actual use, since the height of the connection between the side and bottom of the inner wall of the water tank 9 is higher than the height of the water outlet, and a water outlet pipe 91 is installed at the water outlet, the bottom of the inner wall of the water tank 9 will no longer be horizontal but will have a certain angle of inclination. When the water flows along the angle of inclination, it will be relatively faster.

[0146] Meanwhile, a removable filter screen 93 is installed inside the water outlet pipe 91, and the filter screen 93 has several water outlet holes 931. Therefore, in actual use, since the filter screen 93 is detachable, it is easy to clean or replace.

[0147] Secondly, the bottom surface of the water tank 9 can be the same as the bottom surface of the inner wall, with a height difference. This way, the thickness of the bottom of the water tank 9 is relatively small, which is more conducive to the heat conduction of the heating element 94. Of course, the bottom surface of the water tank 9 can also be different from the bottom surface of the inner wall.

[0148] like Figure 26 and Figure 30 As shown, the bottom surface of the inner wall of the water tank 9 has various shapes, including inclined surfaces or curved surfaces. The inclined surface can be an inclined surface with the entire bottom surface of the inner wall of the water tank 9 set at the same angle, or an inclined surface formed by multiple inclined surfaces with different angles.

[0149] like Figure 25 and Figure 29 As shown, the horizontal cross-section of the water tank 9 is also varied, including circular or polygonal shapes, and the location of the water outlet is also varied, with some located at the center or eccentrically on the bottom surface of the inner wall of the water tank 9. One advantage of the horizontal cross-section of the water tank 9 being polygonal is that the outer surface of the water tank 9 can have an additional surface for attaching the heating element 94. Therefore, the heating element 94 can be placed not only on the bottom surface of the water tank 9, but also on the side surface of the water tank 9.

[0150] Meanwhile, setting the water outlet to the center facilitates manufacturing, while setting it to the eccentric center makes it easier to install the water pump components.

[0151] Furthermore, the aforementioned shape, horizontal cross-section, and outlet location can be randomly combined, and generally, the outer bottom surface of the water tank 9 can be the same as the inner bottom surface, for example... Figure 25 As shown, it combines a circle and an inclined plane, with the outlet pipe 91 eccentrically positioned. The inclined plane has an angle of 15°-30° with the horizontal plane. This design accelerates the water flow rate, and because the circle is relatively conventional, it is easy to manufacture. Furthermore, the eccentric design facilitates the installation of the water pump assembly. For example... Figure 29 As shown, it combines polygons and slopes and sets the water outlet pipe 91 off-center. The bottom of the water tank 9 has multiple slopes. This design can increase the water flow rate and also increase the area for attaching the auxiliary heating plate 94, meaning that the heating plate 94 can also be installed on the side, thereby improving heating efficiency and facilitating the installation of the water pump assembly.

[0152] like Figures 3-5 As shown, the structure of the filter screen 93 is as follows: First, the filter screen 93 is connected to the water outlet pipe 91 by a thread, and the top of the filter screen 93 is provided with a groove 932 for matching with a screwdriver, and the bottom of the groove 932 is provided with several water outlet holes 931.

[0153] In actual use, the filter screen 93 is relatively small, making it difficult for users to hold and operate it directly by hand. Therefore, the groove 932 allows for disassembly and assembly of the filter screen 93 using a screwdriver, such as an Allen screwdriver. Furthermore, the bottom wall of the water tank 9 has a flat surface corresponding to the water outlet pipe 91, and the top of the filter screen 93 is flush with this surface. This is because the water flow needs a buffer at the end, and the flat surface slows down the water flow, preventing excessive force from the water on the filter screen 93.

[0154] Secondly, the water outlet pipe 91 includes an upper part 911 and a lower part 912, and a connecting part 913 is provided between the upper part 911 and the lower part 912. The connecting part 913 is inclined, and the diameter of the upper part 911 is larger than the diameter of the lower part. The filter screen 93 is located inside the upper part 911.

[0155] Therefore, in actual use, the filter screen 93 is prevented from falling from below the water outlet pipe 91 by the different diameters and the setting of the connection part 913.

[0156] like Figures 25-30 As shown, heating elements 94 are provided on the bottom surface and / or the outer side surface of the water tank 9, so that the water tank 9 can be matched with a corresponding number of heating elements 94 according to the actual situation. Moreover, the heating elements 94 are provided on the side surface, which can increase the area for attaching the additional heating elements 94, thereby improving the heating efficiency.

[0157] However, due to the different shapes of the bottom and / or outer sides of the water tank 9, the structure between the heating element 94 and the outer surface of the water tank 9 is different. When the heating element 94 is attached to the outer surface of the water tank 9, the heating element 94 and the water tank 9 can be directly installed together.

[0158] If the heating element 94 does not fit the outer surface of the water tank 9, for example, if the bottom surface or / and the outer side surface of the water tank 9 has an arc or other shape, then a thermally conductive filler is used between the water tank 9 and the heating element 94 to ensure stable heat transfer.

[0159] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
