Positioning structure, mounting assembly, extraction device and coffee machine

Abstract

Part embodiments of the present application relate to a coffee machine, in particular to a positioning structure, a mounting assembly, an extraction device and the coffee machine. The positioning structure comprises at least one positioning assembly, each positioning assembly is arranged on a mounting frame of the coffee machine. When the extraction assembly is screwed into a mounting space of the mounting frame to a first preset position, each positioning assembly can enter each positioning slot of a housing of the coffee machine, so that the mounting frame and the housing are relatively fixed. When the extraction assembly is screwed out of the mounting space of the mounting frame to a second preset position, each positioning assembly is separated from each positioning slot of the housing of the coffee machine, so that the mounting frame and the housing are relatively rotatable. Compared with the prior art, when the extraction assembly is screwed out of the mounting space of the mounting frame, the mounting frame will not follow the rotation of the extraction assembly, ensuring the stability of the assembly between the mounting frame and the housing of the coffee machine.

Description

Technical Field

[0001] Some embodiments of the present invention relate to a coffee machine, and more particularly to a positioning structure, mounting components, extraction device, and coffee machine. Background Technology

[0002] Portable coffee machines, as a type of portable device that can directly extract coffee powder or coffee capsules, are small in size and easy to carry, allowing users to enjoy freshly ground coffee anytime, anywhere.

[0003] To allow users to enjoy coffee anytime, anywhere, current portable coffee machines not only store and heat liquid media but also extract coffee grounds from the heated liquid. Furthermore, most coffee machines currently include an extraction assembly that extracts coffee grounds or capsules. However, the inventors discovered that the extraction assembly is typically attached to the coffee machine's mounting bracket via a threaded connection. Since the mounting bracket is also screwed onto the coffee machine's casing, the bracket often rotates along with the extraction assembly due to the rotational force of the extraction component. This affects the stability of the assembly between the mounting bracket and the coffee machine's casing, making the installation and removal of the extraction assembly extremely inconvenient. Summary of the Invention

[0004] The purpose of this invention is to design a positioning structure, mounting component, extraction device, and coffee machine that can effectively prevent the mounting bracket from rotating along with the extraction component when installing or removing the extraction component, thereby facilitating the installation and removal of the extraction component on the coffee machine.

[0005] To achieve the above objectives, some embodiments of the present invention provide a positioning structure, including: At least one positioning component is mounted on the coffee machine's mounting bracket; When the extraction component is screwed into the mounting space of the mounting bracket to the first preset position, a portion of each of the positioning components enters the positioning slots of the coffee machine housing, thereby fixing the mounting bracket relative to the housing. When the extraction component is rotated out of the mounting space of the mounting bracket to the second preset position, each of the positioning components disengages from the positioning slots of the coffee machine housing, making the mounting bracket and the housing rotatable relative to each other.

[0006] In addition, some embodiments of the present invention also provide an installation component, including: Mounting bracket; the mounting bracket is provided with a mounting groove along its axial direction and a mounting space opposite to the mounting groove; the mounting groove is for being screwed into the housing part of the coffee machine, so that the mounting bracket is detachably connected to the housing; the mounting groove is for being screwed into the extraction component part of the coffee machine, so that the mounting bracket is detachably connected to the extraction component. The positioning structure described above is disposed on the mounting bracket; Wherein, each of the positioning components is used to enter the respective positioning slots of the coffee machine housing when the extraction component is screwed into the installation space to the first preset position, so that the mounting bracket is relatively fixed to the housing; Each of the positioning components is used to disengage from the positioning slots of the coffee machine housing when the extraction component is rotated out to the second preset position in the installation space, so that the mounting bracket and the housing can rotate relative to each other.

[0007] In addition, some embodiments of the present invention also provide an extraction apparatus, comprising: The installation components are as described above; An extraction assembly for screwing into the mounting space of the mounting bracket.

[0008] In addition, some embodiments of the present invention also provide a coffee machine, the coffee machine comprising: The extraction apparatus as described above; Housing; a portion of the housing is screwed into the mounting groove of the mounting bracket and is detachably connected to the mounting bracket; A pumping device, disposed within the housing, is used to pump liquid medium into the extraction device; A liquid storage device, disposed within the housing, is used to deliver liquid medium to the pumping device.

[0009] Compared to the prior art, the embodiments of the present invention, due to the positioning structure consisting of at least one positioning component on the mounting bracket of the coffee machine, allow each positioning component to partially enter the positioning groove of the coffee machine housing when the extraction component is screwed into the mounting space of the mounting bracket to the first preset position. This fixes the mounting bracket and the housing, preventing the mounting bracket from rotating with the extraction component when it is screwed out of the mounting space, thus ensuring the stability of the assembly between the mounting bracket and the coffee machine housing. When the extraction component is screwed out to the mounting space of the mounting bracket to the second preset position, each positioning component can disengage from the positioning groove of the coffee machine housing, allowing the mounting bracket and the housing to rotate relative to each other again, thus not affecting the assembly and disassembly of the mounting bracket and the housing.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of the present invention to facilitate a better understanding of this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0012] Example 1 Embodiment 1 of the present invention relates to a positioning structure, such as Figure 1 and Figure 2 As shown, the positioning structure 11 includes at least one positioning component 111, and each positioning component 111 is disposed on the mounting bracket 12 of the coffee machine.

[0013] When the extraction component 2 of the coffee machine is screwed into the installation space 121 of the mounting bracket 12 to the first preset position, as follows: Figure 4 and Figure 5As shown, each positioning component 111 has a portion that can enter the positioning slots 31 of the coffee machine housing 3, thus fixing the mounting bracket 12 relative to the housing 3. When the extraction component 2 is unscrewed from the mounting space 121 of the mounting bracket 12 to the second preset position, as... Figure 6 and Figure 7 As shown, each positioning component 111 can be disengaged from each positioning groove 31 of the coffee machine housing 3, so that the mounting bracket 12 and the housing 3 can rotate relative to each other.

[0014] As can be seen from the above, since the coffee machine mounting bracket 12 is equipped with a positioning structure 11 consisting of at least one positioning component 111, when the extraction component 2 is screwed into the mounting space 121 of the mounting bracket 12 to the first preset position, each positioning component 111 can partially enter the positioning groove 31 of the coffee machine housing 3, so that the mounting bracket 12 and the housing 3 are relatively fixed at this time. Therefore, when the extraction component 2 is screwed out from the mounting space 121 of the mounting bracket 12, the mounting bracket 12 will not rotate with the rotation of the extraction component 2, ensuring the stability of the assembly between the mounting bracket 12 and the coffee machine housing 3. When the extraction component 2 is screwed out to the mounting space 121 of the mounting bracket 12 to the second preset position, each positioning component 111 can disengage from the positioning groove 31 of the coffee machine housing 3, so that the mounting bracket 12 and the housing 3 can rotate relative to each other at this time, thus not affecting the disassembly and assembly of the mounting bracket 12 and the housing 3.

[0015] Specifically, in some embodiments, such as Figure 2 and Figure 3 As shown, each positioning component 111 includes: a probe 1111 and an elastic element 1112. Among them, combined with... Figure 3 As shown, probe 1111 is mounted on a mounting bracket and is slidable relative to housing 3. An elastic element 1112 is sleeved on probe 1111, and this elastic element 1112 is used to apply a restoring force to probe 1111 in a direction away from housing 3. Furthermore, it is worth noting that in some embodiments, such as... Figure 4 and Figure 5As shown, the side of probe 1111 away from housing 3 also abuts against the coffee machine's powder cup 21. Each probe 1111 has a portion that enters the positioning grooves 31 of housing 3 when the extraction assembly 2 is screwed into the mounting space 121 of the mounting bracket 12 to the first preset position. This allows the mounting bracket 12 and the coffee machine's housing 3 to be relatively fixed, preventing the mounting bracket 12 from rotating with the extraction assembly 2. Simultaneously, each elastic element 1112 can be compressed by the movement of each probe 1111. Conversely, when each probe 1111 has a portion that moves out of the mounting space 121 of the mounting bracket 12 to the second preset position, the elastic element 1112's rebound force allows each probe 1111 to disengage from the positioning grooves 31 of housing 3, allowing the mounting bracket 12 and the coffee machine's housing 3 to rotate relative to each other.

[0016] In addition, to facilitate the installation of each positioning component 111 on the mounting bracket 12, in some embodiments, such as Figure 1 , Figure 5 and Figure 7 As shown, the mounting bracket 12 is also provided with positioning holes 122 for each positioning component 111, through which each positioning component 111 can be stored. Meanwhile, in order to allow the probe 1111 to slide relative to the housing 3, in some embodiments, such as... Figure 3 As shown, the probe 1111 includes a main body 11111, a flange 11112, and a positioning part 11113. The main body 11111 has a head end and a tail end away from the head end along its axial direction. The flange 11112 is partially expanded from the tail end to the head end of the main body 11111. An elastic element 1112 is sleeved on the main body 11111 of the probe 1111. One end of the elastic element 1112 abuts against the flange 11112, and the other end of the elastic element 1112 abuts against the mounting bracket 12. Additionally, as... Figure 1As shown, the positioning part 11113 is disposed at the tail end of the main body 11111, and the positioning part 11113 extends away from the head end. The positioning part 11113 is also used to abut against the extraction component 2 when the extraction component 2 is screwed into the mounting space 121 of the mounting bracket 12, so that the probe 1111 can move relative to the housing 3 of the coffee machine under the movement of the extraction component 2. Therefore, when the extraction component 2 is screwed into the mounting space 121 of the mounting bracket 12, the extraction component 2 can drive each probe 1111 to move towards the housing 3, and at this time, each elastic element 1112 can be gradually compressed under the movement of each probe 1111, so that each probe 1111 can enter the respective positioning groove 31 of the housing 3, thereby realizing the relative fixation between the mounting bracket 12 and the housing 3. Conversely, when the extraction component 2 is rotated out of the mounting space 121 of the mounting bracket 12, each elastic element 1112 can be gradually stretched and restored under its own rebound action, and each probe 1111 can move away from the housing 3 under the rebound action of each elastic element 1112 until each probe 1111 disengages from each positioning groove 31 of the housing 3. At this time, the mounting bracket 12 and the housing 3 can rotate relative to each other.

[0017] Additionally, as a preferred embodiment, in other embodiments, such as Figure 2 As shown, when multiple positioning components 111 are provided, each positioning component 111 is arranged circumferentially around the mounting bracket 12. This allows for better fixation between the mounting bracket 12 and the housing 3 when a portion of the probes 1111 of each positioning component 111 enters the positioning grooves 31 of the housing 3, thereby further improving the stability of the assembly between the mounting bracket 12 and the housing 3. Furthermore, it should be noted that the elastic element 1112 in each positioning component 111 can be a spring. Of course, in other embodiments, the elastic element 1112 can also be other elastic elements with restoring properties. However, in this embodiment, the type of elastic element 1112 is not specifically limited.

[0018] Example 2 Embodiment 2 of the present invention relates to an installation component, such as Figure 1 , Figure 2 and Figure 3 As shown, the mounting assembly 1 includes: a mounting bracket 12 and a positioning structure 11 as described in Embodiment 1. Wherein, as... Figure 3 As shown, the mounting bracket 12 is provided with a mounting groove 129 along its axial direction and a mounting space 121 opposite to the mounting groove 129, and combined with... Figure 4 As shown, the mounting slot 129 of the mounting bracket 12 is screwed into the housing 3 of the coffee machine, so that the mounting bracket 12 and the housing 3 are detachably connected. At the same time, the mounting space 121 is screwed into the extraction component 2 of the coffee machine, so that the mounting bracket 12 and the extraction component 2 are detachably connected.

[0019] In addition, such as Figure 1 and Figure 2 As shown, the positioning structure 11 is disposed on the mounting bracket 12, and each positioning component 111 in the positioning structure 11 is used to extract the component 2 when it is screwed into the mounting space 1212 of the mounting bracket 12 to the first preset position, such as Figure 4 and Figure 5 As shown, each component enters a positioning slot 31 in the housing 3 of the coffee machine, fixing the mounting bracket 12 relative to the housing 3. Simultaneously, each positioning component 111 is also used when the extraction component 2 is screwed out into the mounting space 121 of the mounting bracket 12 to the second preset position, such as... Figure 6 and Figure 7 As shown, the mounting bracket 12 is detached from the positioning slots 31 of the housing 3 of the coffee machine, so that the housing 3 can rotate relative to the mounting bracket 12.

[0020] As can be seen from the above, since the coffee machine mounting bracket 12 is equipped with a positioning structure 11 consisting of at least one positioning component 111, when the extraction component 2 is screwed into the mounting space 121 of the mounting bracket 12 to the first preset position, each positioning component 111 can partially enter the positioning groove 31 of the coffee machine housing 3, so that the mounting bracket 12 and the housing 3 are relatively fixed at this time. Therefore, when the extraction component 2 is screwed out of the mounting space 121 of the mounting bracket 12, the mounting bracket 12 will not rotate with the rotation of the extraction component 2, ensuring the stability of the assembly between the mounting bracket 12 and the coffee machine housing 3. When the extraction component 2 is screwed out to the mounting space 121 of the mounting bracket 12 to the second preset position, each positioning component 111 can disengage from the positioning groove 31 of the coffee machine housing 3, so that the mounting bracket 12 and the housing 3 can rotate relative to each other at this time, thus not affecting the disassembly and assembly of the mounting bracket 12 and the housing 3.

[0021] Specifically, in some embodiments, such as Figure 1 and Figure 3 As shown, the mounting bracket 12 includes a positioning plate 124, an upper ring portion 125, and a lower ring portion 126. The positioning plate 124 has an upper surface 1241 and a lower surface 1242 opposite to the upper surface 1241 along its axial direction, and the positioning plate 124 also has at least one positioning hole 122. The number of positioning holes 122 is the same as the number of positioning components 111, and they correspond uniquely; each positioning component 111 is disposed within its uniquely corresponding positioning hole 122. Furthermore, as... Figure 3 and Figure 4 As shown, the upper ring portion 125 is disposed on the upper surface 1241 of the positioning plate 124, and the upper ring portion 125 forms a mounting groove 129 on the upper surface 1241 of the positioning plate 124, so that after the coffee machine housing 3 is screwed into the mounting groove 129, the upper ring portion 125 can be detachably connected to the housing 3. Finally, as Figure 3 and Figure 4 As shown, the lower ring 126 is disposed on the lower surface 1242 of the positioning plate 124, and the lower ring 126 forms an installation space 121 on the lower surface 1242 of the positioning plate 124, so that after the extraction component 2 is screwed into the installation space 121, the lower ring 126 can be detachably connected to the extraction component 2.

[0022] Furthermore, in order to enable the upper ring 125 to be detachably connected to the housing 3 of the coffee machine, in some embodiments, such as Figure 3 and Figure 9 As shown, the inner side of the upper ring 125 is provided with a plurality of buckles 127, and corresponding to each buckle 127, the outer surface of the housing 3 is provided with a plurality of grooves 32, the number of grooves 32 being the same as the number of buckles 127 and uniquely corresponding. Each groove 32 is used to be embedded in each buckle 127, and each buckle 127 can slide within its uniquely corresponding groove 32, allowing the mounting bracket 12 to rotate relative to the housing 3, thereby achieving a screw connection between the mounting bracket 12 and the housing 3. Specifically, in some embodiments, such as Figure 9 As shown, each slide groove 32 includes: an inclined groove section 321 and a horizontal groove section 322 connected to the inclined groove section 321. One end of the inclined groove section 321 is connected to one end of the horizontal groove section 322, and both extend inclinedly towards the bottom of the housing 3. The included angle between the inclined groove section 321 and the horizontal groove section 322 is an obtuse angle. It is easy to see that the inclined groove section 321 of each slide groove 32 allows each swivel buckle 127 to slide into or out of the horizontal groove section 322 of each slide groove 32. The horizontal groove section 322 of each slide groove 32 allows the mounting bracket 12 to rotate relative to the housing 3. Therefore, when it is necessary to assemble the mounting bracket 12 with the housing 3, such as... Figure 3 and Figure 9 As shown, the screws 127 on the mounting bracket 12 can first be slid into the horizontal grooves 322 through the inclined sections 321 of the sliding grooves 32. Then, the mounting bracket 12 is rotated clockwise so that the screws 127 can slide from one end of the horizontal grooves 322 to the other end, thus achieving the screw connection between the mounting bracket 12 and the housing 3. When it is necessary to remove the mounting bracket 12 from the housing 3, the mounting bracket 12 can be rotated counterclockwise so that the screws 127 can slide from the horizontal sections 322 of the sliding grooves 32 into the inclined sections 321. Then, the screws 127 can gradually slide out from the bottom of the housing 3 along the inclined sections 321, thus removing the mounting bracket 12 from the housing 3. Similarly, in order to enable the lower ring 126 to be detachably connected to the extraction component 2, in some embodiments, such as Figure 3 and Figure 6As shown, the inner side of the lower ring 126 is provided with an internal thread 123, and the lower ring 126 can be threadedly connected to the extraction component 2 through the internal thread 123, so that the extraction component 2 can be screwed into or out of the installation space 121 enclosed by the lower ring 126.

[0023] In addition, to improve the movement performance of each positioning component 111 within each positioning hole 122, in other embodiments, such as Figure 5 and Figure 7 As shown, the lower surface 1242 of the positioning plate 124 also has a portion protruding away from the upper surface 1241 in the direction corresponding to each positioning hole 122, forming annular protrusions 1243. At the same time, each annular protrusion 1243 is coaxially arranged with each positioning hole 122, and each annular protrusion 1243 can be partially sleeved by each elastic element 1112, so that one end of each elastic element 1112 can be fixed by each annular protrusion 1243. Therefore, each elastic element 1112 can stably compress or rebound along its axial direction under the movement of each probe 1111, thereby improving the movement performance of each probe 1111.

[0024] Example 3 Embodiment 2 of the present invention relates to an extraction device, such as... Figure 8 As shown, the extraction device includes: an installation assembly 1 and an extraction assembly 2 as described in Embodiment 1. Wherein, combined with Figure 4 As shown, the extraction component 2 is screwed into the mounting space 121 of the mounting bracket 12.

[0025] Specifically, in some embodiments, such as Figure 4 As shown, the extraction assembly 2 includes: a powder cup 21, a locking member 22, a sealing cap 23, and a water distribution plate 24. The locking member 22 is an annular component used to house the powder cup 21 and to screw into the installation space 121, thereby locking the powder cup 21 within the installation space 121.

[0026] In addition, such as Figure 4 As shown, the sealing cap 23 is located on the side of the powder cup 21 away from the bottom 211. The sealing cap 23 is used to seal the mouth 212 of the powder cup 21, and is also connected to the mounting bracket 12. Figure 10 and Figure 11As shown, the sealing cap 23 is also provided with an inlet hole 231 for receiving the liquid medium pumped out by the pumping device 4, and at least one outlet hole 232 communicating with the inlet hole 231. Each outlet hole 232 is used to deliver the liquid medium into the coffee powder cup 21. The water distribution plate 24 is disposed inside the coffee powder cup 21, and the water distribution plate 24 is also distributed with several drainage holes (not shown in the figure). It is easy to see that when the inlet hole 231 of the sealing cap 23 receives the liquid medium pumped out by the pumping device 4, the liquid medium can be dispersed on the upper surface of the water distribution plate 24 through the outlet holes 232, so that the liquid medium can enter the coffee powder cup 21 through the drainage holes 241 of the water distribution plate 24 to extract the coffee powder in the coffee powder cup 21.

[0027] Furthermore, it is worth mentioning that when the extraction component 2 is screwed into the mounting space 121 of the mounting bracket 12, in order to allow the powder cup 21 to abut against the probes 1111 of each positioning component 111, in some embodiments, such as Figure 11 As shown, the sealing cap 23 includes: a base 234 that can be inserted into the powder cup 21, and an annular protrusion 235 arranged circumferentially around the base 234. Wherein, combined with Figure 10 As shown, a sealing ring 236 is provided around the base 234, which allows the base 234 to form a seal with the cup wall 213 of the powder cup 21. The annular protrusion 235 is used to seal the opening 212 of the powder cup 21. Furthermore, corresponding to the annular protrusion 235, as... Figure 4 As shown, a portion of the wall 213 of the powder cup 21 bends outward from the cup opening 212 to the cup bottom 211, forming a flange 214. This flange 214 can directly abut against the annular protrusion 235 of the sealing cap 23, thereby improving the sealing performance of the sealing cap 23 against the cup opening 212 of the powder cup 21. Furthermore, corresponding to the positioning portion 11113 of each probe 1111, as... Figure 5 and Figure 7 As shown, the annular protrusion 235 of the sealing cover 23 is also provided with through holes 233 corresponding to each probe 1111, so that the positioning part 11113 of each probe 1111 can pass through 11113. Therefore, when the locking member 22 locks the powder cup 21 in the installation space 121, as Figure 4 As shown, the flange 214 of the powder cup 21 can directly abut against the positioning part 11113 of each probe 1111, and drive each probe 1111 to slide in each positioning hole 122 along its axial direction. This allows each positioning part 11113 of the probe 1111 to enter or leave each positioning hole 122 of the mounting frame 12, thereby achieving the fixation or separation between the mounting frame 12 and the extraction assembly 2.

[0028] Example 4 Embodiment 3 of the present invention relates to a coffee machine, such as Figure 8 and Figure 10As shown, the coffee machine includes: a housing 3, an extraction device as described in Embodiment 3, a pumping device 4, and a storage device 5. The extraction device is detachably mounted at the bottom of the housing 3, while the pumping device 4 is disposed within the housing 3 and is used to pump liquid medium to the extraction device. Secondly, as... Figure 10 As shown, the liquid storage device 5 is disposed inside the housing 3, and the liquid storage device 5 is used to deliver liquid medium to the pumping device 4.

[0029] Specifically, as can be seen from the above embodiment 1, since the housing 3 and the mounting bracket 12 of the mounting assembly 1 are connected by a screw connection, and since the inner side of the upper ring portion 125 of the mounting bracket 12 is provided with several screw fasteners 127, corresponding to each screw fastener 127, such as Figure 3 and Figure 9 As shown, the outer surface of the housing 3 is provided with a plurality of sliding grooves 32, and the number of sliding grooves 32 is the same as the number of swivel buckles 127, and they correspond uniquely. Each sliding groove 32 is used to be embedded in each swivel buckle 127, and each swivel buckle 127 can slide within its uniquely corresponding sliding groove 32, so that the mounting bracket 12 can rotate relative to the housing 3, thereby realizing the swivel connection between the mounting bracket 12 and the housing 3. Specifically, in some embodiments, such as Figure 9 As shown, each groove 32 includes: an inclined groove section 321 and a horizontal groove section 322 connected to the inclined groove section 321. The inclined groove section 321 is connected to one end of the horizontal groove section 322 and extends inclinedly towards the bottom of the housing 3, and is combined with... Figure 9 The angle formed between the inclined groove section 321 and the horizontal groove section 322 shown is an obtuse angle. It is easy to see that the inclined groove section 321 of each slide 32 allows each swivel buckle 127 to slide into or out of the horizontal groove section 322 of each slide 32, while the horizontal groove section 322 of each slide 32 allows the mounting bracket 12 to rotate relative to the housing 3. Therefore, when it is necessary to assemble the mounting bracket 12 with the housing 3, such as... Figure 3 and Figure 9 As shown, the screws 127 on the mounting bracket 12 can be slid into the horizontal grooves 322 through the inclined sections 321 of the sliding grooves 32. Then, the mounting bracket 12 can be rotated clockwise so that the screws 127 can slide from one end of the horizontal grooves 322 to the other end, thus achieving the screw connection between the mounting bracket 12 and the housing 3. When it is necessary to remove the mounting bracket 12 from the housing 3, the mounting bracket 12 can be rotated counterclockwise so that the screws 127 can slide from the horizontal sections 322 of the sliding grooves 32 into the inclined sections 321. Then, the screws 127 can gradually slide out from the bottom of the housing 3 along the inclined sections 321, thus removing the mounting bracket 12 from the housing 3.

[0030] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made in form and detail without departing from the spirit and scope of the present invention.
