Technical Field
[0001] This utility model relates to the field of coffee machines, specifically to a mini multi-functional coffee machine. Background Technology
[0002] Traditional portable coffee machines have relatively limited functions, especially those specifically designed for brewing coffee capsules. They can only brew coffee from coffee capsules and cannot brew coffee from coffee bags or ground coffee, thus failing to meet the need for multiple uses in one machine.
[0003] A coffee machine is currently available, including a brewing base and a water tank. The brewing base has a brewing chamber and a brewing lid that is openable and closable to seal the brewing chamber. The inner end face of the brewing lid has a water inlet cap that communicates with the water tank. Although its brewing chamber can accommodate any of the following: coffee bag brewing components, coffee powder brewing components, or coffee capsule brewing components, it lacks a safety design. When the brewing lid is open, if the user accidentally touches the start button, hot water will flow out from the water inlet cap, posing a safety hazard. Utility Model Content
[0004] The purpose of this invention is to provide a highly safe mini multi-functional coffee machine.
[0005] To achieve the above objectives, this utility model provides a mini multi-functional coffee machine, including a body, a brewing head, a water supply module, and a heating module. The heating module is used to heat the water supply module. The brewing head has an openable brewing chamber. The water supply module includes a water inlet path and a water pump. The water inlet path supplies water to the brewing chamber through the water pump. The body also has a water circuit shut-off component and a micro switch. The micro switch is electrically connected to the water pump. The water circuit shut-off component is located on the water inlet path. The water circuit shut-off component can force the micro switch to close or open, thereby energizing or de-energizing the water pump, and is used to force the water pump to be de-energized before opening the brewing chamber.
[0006] As can be seen from the above scheme, by setting up a water circuit shut-off component to force the micro switch to disconnect, the water pump is de-energized. Before opening the brewing chamber, the water pump is de-energized first, which prevents hot water from flowing out due to accidental touch of the start button when the brewing chamber is open. This effectively avoids safety accidents caused by accidental hot water leakage and improves its safety. When the brewing chamber is closed, the water circuit shut-off component forces the micro switch to close, which energizes the water pump. Only then can the water supply module work normally.
[0007] A further embodiment is that the water circuit shut-off component includes a lifting movable part and a lifting bracket. The lifting movable part includes a connecting part and a plug-in part. The connecting part is movably connected to the lifting bracket, and the plug-in part is inserted into the water inlet circuit. The lifting movable part can move up and down relative to the lifting bracket to drive the plug-in part to move. A micro switch is set vertically and vertically corresponding to the lifting movable part. When the lifting movable part moves down and abuts against the micro switch, the lifting movable part forces the micro switch to close, and the water pump is powered on. When the lifting movable part moves up and separates from the micro switch, the micro switch is opened, and the water pump is powered off.
[0008] As can be seen from the above scheme, when the lifting movable part is in the low position, it abuts against the micro switch, causing the micro switch to close and thus powering on the water pump. The user can then start the heating module and / or water supply module to perform the brewing operation. When the lifting movable part moves upward, it separates from the micro switch, which automatically disconnects, de-energizing the water pump. The user can then open the brewing chamber and insert any one of the following: a coffee bag brewing component, a coffee powder brewing component, or a coffee powder capsule brewing component. Even if the user accidentally touches the start button, no hot water will flow out, offering the advantage of high safety.
[0009] A further design includes a first water inlet and an internal channel in the connector. The first water inlet is connected to the upper part of the internal channel, and the internal channel is connected to the water inlet path through the first water inlet. The height of the first water inlet within the water inlet path is adjustable. The machine body is also equipped with a mounting base, and the brewing head is connected to the mounting base. The mounting base is equipped with a second water inlet and a water-passing assembly. The second water inlet is connected to the brewing chamber, and the water-passing assembly covers the second water inlet. The water inlet path is located within the water-passing assembly, and the connector is inserted vertically into the water-passing assembly, corresponding vertically to the second water inlet. The lower part of the internal channel is connected to the second water inlet.
[0010] As can be seen from the above scheme, compared with the scheme of directly using water pipes as the water inlet, the above configuration makes it easier to insert the plug-in part into the water inlet; by setting the first water inlet and the internal channel, the water in the water inlet enters the internal channel through the first water inlet and then flows to the second water inlet.
[0011] A further embodiment includes a water-passing component and a water-passing seal. The water-passing seal is sealed between the water-passing component and the mounting base. The water-passing component has a cavity, which includes a first cavity and a second cavity that are interconnected. The water inlet path includes the first cavity and the second cavity. The top wall of the first cavity is higher than the top wall of the second cavity. The plug is inserted into the first cavity. The height of the first water inlet can be higher or lower than the top wall of the second cavity. When the height of the first water inlet is higher than the top wall of the second cavity, the water inlet flow rate is less than when the first water inlet is lower than the top wall of the second cavity.
[0012] As can be seen from the above scheme, with the above settings, when the height of the first water inlet is higher than the top wall of the second cavity, the first water inlet is higher than the highest water level in the second cavity, which helps to reduce the water intake of the first water inlet and prevent the water remaining in the water inlet channel from continuing to flow to the first water inlet; when it is necessary to increase the water intake of the second water inlet, it is only necessary to lower the height of the first water inlet.
[0013] A further embodiment includes a water-passing assembly, a water-passing sleeve, a first sealing ring, and a second sealing ring. The water-passing sleeve is disposed inside the first cavity and sleeved on the outside of the insertion part. The upper part of the water-passing sleeve is sealed to the top wall of the first cavity through the first sealing ring, and the lower part of the water-passing sleeve is sealed to the bottom wall of the first cavity through the second sealing ring. An annular channel is provided between the inner wall of the water-passing sleeve and the outer wall of the insertion part, and the annular channel is connected to the first water inlet. A water-passing groove is provided at the lower part of the water-passing sleeve, and the water-passing groove is connected to the annular channel and the first cavity respectively.
[0014] As can be seen from the above scheme, the above settings allow water to enter the annular channel from the water passage groove at the bottom of the water passage sleeve, which helps to reduce the flow path of the water into the annular channel and further prevents the water remaining in the water inlet from continuing to flow towards the first water inlet, thereby reducing the amount of water entering the first water inlet.
[0015] A further option is to rotatably connect the lifting movable component to the lifting bracket, allowing the lifting movable component to rotate relative to the lifting bracket, thereby forcing the lifting movable component to move up and down relative to the lifting bracket.
[0016] A further embodiment is that the connecting part is located on the inner side of the lifting bracket, a first sliding engagement part is provided on the outer wall of the connecting part, and a second sliding engagement part is provided on the inner wall of the lifting bracket. The first sliding engagement part or the second sliding engagement part extends spirally along the axial direction, and the first sliding engagement part and the second sliding engagement part are in concave-convex engagement and can slide relative to each other; the first sliding engagement part is set as a protrusion, and the second sliding engagement part is set as a groove, or the first sliding engagement part is set as a groove, and the second sliding engagement part is set as a protrusion.
[0017] As can be seen from the above scheme, the above settings enable the connecting part to rotate relative to the lifting bracket while simultaneously moving up and down, which has the advantages of simple structure and convenient operation.
[0018] A further embodiment includes a locking ring with a first actuating part and a second actuating part. The first actuating part protrudes outside the body, while the second actuating part is located inside the body. A third actuating part is provided on the lifting movable part, which is slidably connected to the second actuating part. When the lock ring rotates around its own axis, the second actuating part can drive the lifting movable part to rotate.
[0019] As can be seen from the above scheme, with the above settings, the user can apply force to the first actuating part on the outside of the machine body, and the locking ring drives the lifting movable part to rotate through the second actuating part and the third actuating part, and the lifting movable part moves up and down during the rotation.
[0020] A further option is that the water supply module also includes a water tank, which is connected to the water inlet via a water pump; the heating module includes a heating element, which is installed on the bottom wall and / or side wall of the water tank.
[0021] As can be seen from the above scheme, the above settings enable the heating module to directly heat the water tank, improving heating efficiency, and also help save space.
[0022] A further embodiment is that the brewing head includes a brewing holder and a fixed container. The brewing holder is connected to the machine body, and the fixed container is detachably connected to the brewing holder. The brewing chamber is located between the fixed container and the brewing holder. The bottom of the fixed container has a coffee outlet that communicates with the brewing chamber. The brewing chamber can be equipped with any one of a coffee bag brewing component, a coffee powder brewing component, or a coffee powder capsule brewing component.
[0023] As can be seen from the above scheme, with the above settings, when the brewing chamber is opened, the user can put in any one of the coffee bag brewing component, coffee powder brewing component, or coffee powder capsule brewing component to achieve multi-functional settings.

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation
[0039] See Figures 1 to 3 and combined Figure 11 The mini multi-functional coffee machine provided in this embodiment includes a body 10 and a base 20. The body 10 is disposed on the first end of the base 20, and the second end of the base 20 is provided with a cup holder 201 for holding cups.
[0040] The main body 10 is equipped with a brewing head 1, a water supply module 2, a heating module 3, and a control module. The brewing head 1 is located directly above the cup holder 201, and the brewing head 1 has an openable brewing chamber 13. The control module is connected to both the water supply module 2 and the heating module 3.
[0041] The water supply module 2 includes a water tank 21, a water pump 22, water pipes, and an inlet water passage. The water pipes are connected to the outlet 211 at the bottom of the water tank 21 and the inlet of the water pump 22. The outlet 221 of the water pump 22 is connected to the brewing chamber 13 through the inlet water passage. The water tank 21 supplies water to the brewing chamber 13 through the water pump 22 and the inlet water passage.
[0042] The heating module 3 includes a heating element, which can be disposed on the bottom wall and / or side wall of the water tank 21 for heating the water in the water tank 21. The heating element can be a heating wire or a heating plate; in this embodiment, a heating plate is preferred. The heating plate can be directly disposed on the bottom wall of the water tank 21, such as... Figure 11 As shown, this is to improve heating efficiency.
[0043] Combination Figures 3 to 10The upper part of the body 10 is provided with an outer cover 101 and a mounting base 102, with the outer cover 101 covering the mounting base 102. The water tank 21 is located on the upper side of the first end of the mounting base 102 and inside the outer cover 101, the brewing head 1 is located on the lower side of the second end of the mounting base 102, and the water pump 22 is located on the middle part of the mounting base 102.
[0044] The second end of the mounting base 102 is provided with a second water inlet 1021 and a water-passing assembly 4. The second water inlet 1021 extends vertically through the mounting base 102 and communicates with the brewing chamber 13. The water-passing assembly 4 is located between the outlet end 221 of the water pump 22 and the second water inlet 1021. The water inlet path is located within the water-passing assembly 4 and communicates with both the outlet end 221 of the water pump 22 and the second water inlet 1021. Specifically:
[0045] The water-passing assembly 4 includes a water-passing component 41 and a water-passing seal 42. The water-passing component 41 is fixedly connected to the mounting base 102 and covers the second water inlet 1021. A cavity is provided inside the water-passing component 41, and the water-passing seal 42 is disposed around the cavity and is sealed between the water-passing component 41 and the mounting base 102 to ensure the sealing of the cavity. The cavity is stepped and includes a first cavity 411 and a second cavity 412 that are interconnected. The top wall of the first cavity 411 is higher than the top wall of the second cavity 412. The water inlet path includes the first cavity 411 and the second cavity 412. The outlet end 221 of the water pump 22 is inserted into the second cavity 412 and communicates with the second cavity 412. In order to improve the water intake speed, the mounting base 102 has a groove 1022 on the bottom wall of the second cavity 412. The groove 1022 is recessed into the surface of the mounting base 102 and corresponds vertically to the water outlet 221 of the water pump 22.
[0046] The body 10 also contains a water circuit shut-off component 5 and a micro switch 54.
[0047] In one embodiment, the micro switch 54 is directly electrically connected to the water pump 22. Preferably, the micro switch 54 and the water pump 22 are connected in series. When the micro switch 54 is open, the water pump 22 is directly de-energized; when the micro switch 54 is closed, the water pump 22 is energized.
[0048] In another implementation, the micro switch is electrically connected to the water pump, that is, the control module is connected to both the water pump and the micro switch. When the micro switch is open, the control module controls the water pump to be powered off; when the micro switch is closed, the control module controls the water pump to be powered on.
[0049] The water circuit shut-off component 5 is installed on the water inlet circuit. This component mechanically forces the microswitch 54 to close or open, energizing or de-energizing the water pump 22. By forcing the water pump 22 to de-energize before opening the brewing chamber 13, hot water leakage is prevented due to accidental activation of the start button, thus improving safety. Specifically:
[0050] The water circuit shut-off assembly 5 includes a lifting movable component 51 and a lifting bracket 52. The lifting movable component 51 includes a connecting portion 511 and a plug-in portion 512, with the plug-in portion 512 positioned below the connecting portion 511. The lifting bracket 52 is fixedly connected to the second end of the mounting base 102. The connecting portion 511 is movably connected to the lifting bracket 52, allowing the lifting movable component 51 to move up and down relative to the lifting bracket 52, thereby causing the plug-in portion 512 to move up and down. A micro switch 54 is vertically corresponding to the lifting movable component 51; preferably, the micro switch 54 is positioned directly below the lifting movable component 51.
[0051] When the lifting movable part 51 moves down to the low position, the lifting movable part 51 abuts against the micro switch 54 and forces the micro switch 54 to close. At this time, the water pump 22 is powered on, and the user can brew coffee. When the lifting movable part 51 rises to the high position, the lifting movable part 51 moves away from the micro switch 54, the micro switch 54 automatically disconnects, the water pump 22 is de-energized, and the user can open the brewing chamber 13.
[0052] The connector 512 is inserted into the water inlet channel. The connector 512 has a first water inlet 5121 and an internal channel 5122. The first water inlet 5121 is connected to the upper part of the internal channel 5122. One end of the first water inlet 5121 is connected to the water inlet channel, and the other end of the first water inlet 5121 is connected to the brewing chamber 13 through the internal channel 5122.
[0053] Furthermore, the insertion part 512 is inserted into the first cavity 411 and corresponds vertically to the second water inlet 1021, with the lower part of the internal channel 5122 communicating with the second water inlet 1021. The lifting movable part 51 can move up and down relative to the lifting bracket 52, thereby driving the insertion part 512 and the first water inlet 5121 to move up and down, so that the height of the first water inlet 5121 can be higher or lower than the top wall of the second cavity 412.
[0054] When the first inlet 5121 is higher than the top wall of the second cavity 412, the water inlet volume of the first inlet 5121 is less than the water inlet volume when the first inlet 5121 is lower than the top wall of the second cavity 412. This helps to reduce the flow of hot water remaining in the water inlet into the first inlet 5121 after the water pump 22 is de-energized, which helps to further improve its safety.
[0055] Combination Figure 5 and Figure 9To further reduce the risk of hot water remaining in the water inlet circuit accidentally entering the first water inlet 5121, the water-passing assembly 4 in this embodiment also includes a water-passing sleeve 43, a first sealing ring 44, and a second sealing ring 46. The water-passing sleeve 43 is disposed inside the first cavity 411 and sleeved on the outside of the insertion part 512. An annular channel 45 is provided between the inner wall of the water-passing sleeve 43 and the outer wall of the insertion part 512, and the first water inlet 5121 communicates with the annular channel 45. The upper part of the water-passing sleeve 43 is sealed to the top wall of the first cavity 411 through the first sealing ring 44, and the lower part of the water-passing sleeve 43 is sealed to the bottom wall of the first cavity 411 through the second sealing ring 46. The lower part of the water-passing sleeve 43 is also provided with multiple water-passing grooves 431. The multiple water-passing grooves 431 are arranged along the circumference of the water-passing sleeve 43. The water-passing grooves 431 are recessed in the bottom wall of the water-passing sleeve 43. The water-passing grooves 431 are respectively connected to the annular channel 45 and the second cavity 412, so that the water flow in the second cavity 412 can enter the annular channel 45 through the water-passing grooves 431, which helps to reduce the flow path of the water flow.
[0056] When the first inlet 5121 is in a high position, water will not accidentally enter the first inlet 5121, which helps to further improve safety.
[0057] Combination Figure 6 , Figure 9 and Figure 10 In this embodiment, the lifting movable component 51 is rotatably connected to the lifting bracket 52. The lifting movable component 51 can rotate relative to the lifting bracket 52, thereby forcing the lifting movable component to move up and down relative to the lifting bracket 52. Specifically:
[0058] In this embodiment, the connecting portion 511 is disposed on the inner side of the lifting bracket 52. A first sliding engagement portion is disposed on the outer wall of the connecting portion 511, and a second sliding engagement portion is disposed on the inner wall of the lifting bracket 52. The first sliding engagement portion extends spirally along the axial direction of the connecting portion 511, or the second sliding engagement portion extends spirally along the axial direction of the lifting bracket 52. The first sliding engagement portion and the second sliding engagement portion are in a concave-convex fit and can slide relative to each other.
[0059] In one embodiment, the first sliding engagement portion is a protrusion 5111, and the number of protrusions 5111 is set to several. The several protrusions 5111 are arranged circumferentially along the connecting portion 511, and the protrusions 5111 extend arcuately along the axial direction of the connecting portion 511. The second sliding engagement portion is a groove 521, and the groove 521 extends spirally along the axial direction of the lifting bracket 52. The protrusions 5111 are embedded in the groove 521 and can slide along the extending direction of the groove 521.
[0060] In another embodiment, the first sliding engagement part is a groove that extends spirally along the circumference of the connecting part, and the second sliding engagement part is a protrusion that extends arcuately along the axial direction of the lifting bracket. The protrusion is embedded in the groove and can slide along the extension direction of the groove.
[0061] When the lifting movable component 51 rotates relative to the lifting bracket 52 around its own axis, the lifting movable component 51 can move up and down relative to the lifting bracket 52 at the same time.
[0062] To facilitate user control of the rotation of the lifting movable component 51 located inside the body 10 from the outside of the body 10, the water circuit shut-off assembly 5 of this embodiment also includes a locking ring 53. The locking ring 53 is movably connected to the upper part of the outer cover 101 and is connected to the lifting movable component 51. The user can drive the lifting movable component 51 to rotate through the locking ring 53. Specifically:
[0063] The locking ring 53 is provided with a first actuating part 531 and a second actuating part 532. The first actuating part 531 protrudes beyond the outer cover 101, and the second actuating part 532 is disposed inside the outer cover 101 and extends vertically. The free end of the second actuating part 532 is provided with a hook for connecting with the annular flange 1011 of the outer cover 101, so that the locking ring 53 will not easily detach from the outer cover 101, while allowing it to rotate horizontally relative to the outer cover 101. The lifting movable part 51 is provided with a third actuating part 513, which protrudes upward and outward, and has a groove 5131 that mates with the second actuating part 532. The second actuating part 532 can slide vertically into the groove 5131.
[0064] The user can manually move the first actuating part 531 to make the locking ring 53 rotate around its own axis. At this time, the second actuating part 532 can drive the lifting movable part 51 to rotate through the third actuating part 513, and during the rotation, the slot 5131 can slide along the extension direction of the second actuating part 532.
[0065] The third actuating part 513 may be integrally formed with the lifting movable part 51, or the third actuating part 513 may be set on an external part, and the external part may be fixed to the lifting movable part 51 by screws. This embodiment does not impose any restrictions.
[0066] A control panel 55 is installed inside the locking ring 53. The locking ring 53 can rotate relative to the control panel 55. The control panel 55 is equipped with a temperature display area, control buttons, and a power display area. The user can start or stop the heating module 3 and / or the water supply module 2 by pressing the control buttons.
[0067] The mini multi-functional coffee machine in this embodiment also includes a power supply module 6, which is connected to the control module, heating module 3, water supply module 2 and micro switch 54 respectively. The power supply module 6 can be a dry cell battery or a rechargeable battery, etc.
[0068] See Figure 12 and Figure 13 and combined Figure 5 and Figure 9 The brewing head 1 includes a brewing holder 11 and a fixing container 12. The brewing holder 11 is connected to the mounting base 102. The brewing holder 11 includes a locking plate 111, a first fixing member 112, and a second fixing member 113. One end of the first fixing member 112 is connected to one end of the second fixing member 113. The locking plate 111 is fixed to the first fixing member 112 and the second fixing member 113 respectively by screws. For easy assembly, a flange that can overlap is provided between the first fixing member 112 and the second fixing member 113. After the two flanges overlap, they are then locked together by the locking plate 111 and screws. The first fixing member 112 has a third water inlet 1121 in the middle and the locking plate 111 has a fourth water inlet 1111 in the middle. The third water inlet 1121 and the fourth water inlet 1111 are coaxially arranged. When the first water inlet 5121 is in a low position, the lower part of the plug part 512 can be inserted into the second water inlet 1021, the fourth water inlet 1111 and the third water inlet 1121, so that the internal channel 5122 of the plug part 512 is connected to the brewing chamber 13.
[0069] The fixed container 12 is detachably connected to the brewing holder 11. Specifically, the fixed container 12 and the brewing holder 11 are snap-fitted or threaded together. The brewing chamber 13 is located between the fixed container 12 and the brewing holder 11, and the bottom of the fixed container 12 is provided with a coffee outlet that communicates with the brewing chamber 13.
[0070] The brewing chamber 13 can be equipped with any one of the following: a coffee bag brewing component (not shown in the figure), a coffee powder brewing component 8, or a coffee powder capsule brewing component 7.
[0071] The coffee capsule brewing assembly 7 includes a capsule 71 and a puncture member 72, with the puncture member 72 located at the lower part of the capsule 71. During brewing, the user simply inserts the capsule 71 and the puncture member 72 together into the brewing chamber 13.
[0072] The coffee brewing assembly 8 includes a coffee container 81 and a water distributor 82. The coffee container 81 holds the coffee powder, and the water distributor 82 is located on the upper part of the coffee container 81. The water distributor 82 has multiple evenly spaced water holes to facilitate the even flow of hot water into the coffee container 81. During brewing, the user simply places the coffee brewing assembly 8 into the brewing chamber 13.
[0073] In summary, this utility model, by setting the water circuit shut-off component 5 to force the micro switch to disconnect, thereby de-energizing the water pump, forces the water pump to disconnect before opening the brewing chamber 13. This prevents hot water from flowing out due to accidental touch of the start button while the chamber is open, effectively avoiding safety accidents caused by accidental hot water leakage and improving its safety. After the brewing chamber 13 is closed, the water circuit shut-off component 5 forces the micro switch to close, energizing the water pump. Only then can the water supply module 2 and the heating module 3 work normally.
[0074] Finally, it should be emphasized that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
