Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular, to a locking mechanism, a brewing chamber, and a brewing machine. Background Art

[0002] Capsule beverage brewing machines are very popular because they are more convenient and hygienic than manual brewing. The main reason why machine brewing is faster than manual brewing is that the brewing system formed by the brewing machine and the capsule exerts pressure on the contents placed in the capsule for brewing, and the existence of pressure promotes the precipitation of active substances in the contents. The pressurized brewing of capsule beverages is completed in the brewing chamber of the machine. The brewing pressure of capsule beverages is mostly between 3 bar and 12 bar. This requires the brewing chamber to have reliable pressure resistance. Once the pressure-resistant measures fail, there is a great possibility of problems such as bursting of the chamber and leakage of water, and splashing of hot water during the brewing process, posing a great safety hazard.

[0003] Generally, there is a self-sealing and pressure-resistant structure between the lid and the body of the brewing chamber of the existing pressurized brewing machine, but there are still cases of chamber bursting, indicating that the inherent pressure-resistant measures are not foolproof. If the sealing and pressure-resistant strength is designed too large simply to meet sufficient pressure resistance, it will be difficult to open the lid of the brewing chamber.

[0004] At the same time, after brewing, most of the existing brewing machines need to manually flip up the lid of the brewing chamber or open the lid through a linked handle to take out the discarded capsule or make the capsule drop automatically. Due to the existence of the inherent sealing and pressure-resistant strength of the brewing machine, it takes force to open the brewing chamber, which causes inconvenience in operation.

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] Implementation Method 1

[0059] like Figure 1As shown in the figure, the present invention provides a locking mechanism, including: at least one first male buckle structure 101, one end of the first male buckle structure 101 is provided with a first buckling protrusion 102, and the other end of the first male buckle structure 101 is connected to the first component 200 through a transmission structure 105; at least one first female buckle structure 103 is arranged on the second component 300, and the first buckling protrusion 102 can move in its buckling direction A to buckle with the first female buckle structure 103 to form a locked state; an unlocking structure 104 can push the transmission structure 105 to move, and the transmission structure 105 drives the first buckling protrusion 102 to move in its unlocking direction B to release the buckle with the first female buckle structure 103 to form an unlocked state.

[0060] Wherein, the buckling direction A of the first buckling protrusion 102 is the protruding direction of the first buckling protrusion 102, and the unlocking direction B of the first buckling protrusion 102 is the opposite direction of its protruding direction.

[0061] In the locking mechanism of the present invention, by setting the unlocking structure 104 to push the transmission structure 105, the transmission structure 105 drives the first buckling protrusion 102 to move in its unlocking direction B to release the buckle with the first female buckle structure 103 on the second component 300. The operation is simple. Therefore, when the first buckling protrusion 102 moves in its buckling direction A to buckle with the first female buckle structure 103, a large sealing pressure resistance can be designed between the first component 200 and the second component 300, meeting the pressure resistance requirements while avoiding the problem that the first buckling protrusion 102 cannot release the buckle with the first female buckle structure 103.

[0062] Specifically, the first male buckle structure 101 is generally hook-shaped. In this embodiment, the first male buckle structure 101 includes an elastic buckle arm 106. The elastic buckle arm 106 is arranged along the pushing direction of the unlocking structure 104 and is located on the side of the elastic transmission arm 109 away from the unlocking structure 104. One end of the elastic buckle arm 106 is connected to the first buckling protrusion 102, and the other end of the elastic buckle arm 106 is connected to the elastic buckle arm 106 through a bending arm 107. The first male buckle structure 101 is inserted into the first female buckle structure 103, and the first buckling protrusion 102 is buckled with the first female buckle structure 103 along its buckling direction A by using the elastic restoring force of the elastic buckle arm 106.

[0063] As Figure 1 and Figure 4 shown in the figure, in this embodiment, the first female buckle structure 103 includes a first buckle hole 108. The first buckling protrusion 102 passes through the first buckle hole 108 and moves in its buckling direction A to buckle with the edge part of the first buckle hole 108 to form a locked state. Optionally, the first female buckle structure may include groove structures such as a buckle groove or a card slot.

[0064] As Figure 1 、 Figure 2 and Figure 4As shown, specifically, the top surface of the first fastening protrusion 102 is a fastening surface, which is arranged perpendicular to the insertion direction C of the first male fastening structure 101. This fastening surface can abut against the edge part of the first fastening hole 108 to prevent the first fastening protrusion 102 from disengaging from the first fastening hole 108. The bottom surface of the first fastening protrusion 102 is a guiding inclined surface, which is inclined along the insertion direction C of the first male fastening structure 101 towards the unlocking direction B of the first fastening protrusion 102 (i.e., the radially inward direction of the first fastening hole 108). This inclined surface can abut and slide along the inner wall surface of the first fastening hole 108 to push the first male fastening structure 101 to pass through the first fastening hole 108. Then, under the action of the elastic restoring force of the first male fastening structure 101 itself, the first fastening protrusion 102 moves towards the fastening direction A (i.e., the radially outward direction of the first fastening hole 108) and engages with the edge part of the first fastening hole 108. The connection between the first fastening protrusion 102 and the elastic fastening arm 106 has an oblique angle transition to prevent the first fastening protrusion 102 from being deformed and broken under force during fastening.

[0065] As Figure 1 and Figure 2 shown, in the embodiment of the present invention, the transmission structure 105 includes an elastic transmission arm 109. The elastic transmission arm 109 can be elastically deformed under the push of the unlocking structure 104 to drive the first fastening protrusion 102 to move along its unlocking direction B. After the elastic transmission arm 109 loses the push of the unlocking structure 104, it can automatically reset by using its own elastic restoring ability, thereby driving the first fastening protrusion 102 to return to the initial position as well. Specifically, the elastic transmission arm 109 is inclined along the push direction F of the unlocking structure 104 towards the side close to the unlocking structure 104, so that the unlocking structure 104 can push the elastic transmission arm 109 to elastically deform towards the side away from the unlocking structure 104, thereby driving the first fastening protrusion 102 to move along its unlocking direction.

[0066] As Figure 1 and Figure 2As shown, in this embodiment, the first component 200 is provided with a first through hole 110. The elastic transmission arm 109 is connected to the side of the first component 200 away from the second component 300. The elastic buckle arm 106 passes through the first through hole 110. The first buckling protrusion 102 extends to the side of the first component 200 close to the second component 300, and the first buckling protrusion 102 protrudes in a direction away from the unlocking structure 104. Among them, the buckling direction A of the first buckling protrusion 102 is the direction away from the unlocking structure 104, and the unlocking direction B of the first buckling protrusion 102 is the direction close to the unlocking structure 104. The installation position of the unlocking structure 104 is related to its pushing direction F. In this embodiment, the unlocking structure 104 is installed near the second component 300 to push the elastic transmission arm 109 from the side of the first component 200 close to the second component 300. The elastic transmission arm 109 deforms toward the side away from the unlocking structure 104 under the push of the unlocking structure 104 and transmits it to the bending arm 107, thereby driving the first buckling protrusion 102 on the elastic buckle arm 106 to move in the unlocking direction B to release the buckling. When the unlocking structure 104 retracts, the elastic deformation of the elastic transmission arm 109 gradually recovers until the unlocking structure 104 separates from the elastic transmission arm 109, and the elastic transmission arm 109 returns to its initial state.

[0067] As Figure 2 shown, specifically, the gap between the first through hole 110 and the elastic buckle arm 106 is used to provide space for the elastic deformation of the elastic buckle arm 106. The elastic buckle arm 106 passes through the first through hole 110 along the axial direction of the first through hole 110, so that the part of the elastic buckle arm 106 connected to the bending arm 107 is located above the first through hole 110, and the part of the elastic buckle arm 106 provided with the first buckling protrusion 102 is located below the first through hole 110. The elastic buckle arm 106 is not located in the middle position of the first through hole 110, but is arranged close to the unlocking structure 104, reserving enough space for the part of the elastic buckle arm 106 connected to the bending arm 107 to move toward the side away from the unlocking structure 104, so that the part of the elastic buckle arm 106 provided with the first buckling protrusion 102 can move toward the side close to the unlocking structure 104 to release the buckling. In addition, the first through hole 110 plays a limiting role in the elastic deformation of the elastic buckle arm 106, preventing the part of the elastic buckle arm 106 provided with the first buckling protrusion 102 from moving excessively in the unlocking direction B and abutting against the side wall of the first buckle hole 108 close to the unlocking structure 104, which hinders the first buckling protrusion 102 from disengaging from the first buckle hole 108.

[0068] As Figure 1 and Figure 2As shown, the elastic drive arm 109, the bending arm 107, the elastic buckle arm 106, the first buckling projection 102 and the first component 200 are integrally injection-molded. The size of the first buckling projection 102 is smaller than that of the first perforation 110 to facilitate demolding during production and manufacturing. The bending arm 107 is bent at approximately 90°, and the bending part is treated with chamfering and thickening to enhance the strength of the entire bending arm 107 and prevent the elastic buckle arm 106 from breaking during the buckling and unlocking processes.

[0069] As Figure 1 , Figure 2 and Figure 4 shown, compared with the first perforation 110, the first buckling hole 108 is arranged closer to the unlocking structure 104, that is, there is a certain dislocation between the first perforation 110 and the first buckling hole 108 to match the position of the first buckling projection 102. That is, when the elastic buckle arm 106 does not undergo elastic deformation, the position of the first buckling projection 102 corresponds to that of the first perforation 110, and when the elastic buckle arm 106 undergoes elastic deformation, the position of the first buckling projection 102 corresponds to that of the first buckling hole 108, so that after the first buckling projection 102 slides out of the first buckling hole 108, it can move in its buckling direction A and buckle with the edge part of the first buckling hole 108.

[0070] It should be noted that the buckling direction A and the unlocking direction B of the first buckling projection 102 are related to the direction in which it protrudes. The elastic deformation direction of the elastic drive arm 109 and the pushing direction of the unlocking structure 104 can be designed according to the unlocking direction B of the first buckling projection 102, and are not limited to the structure shown in this embodiment. Therefore, the installation position of the unlocking structure 104 is not limited to being installed on the component near the second component 300 in this embodiment, and can also be installed on the second component 300, the first component 200 or the component near the first component 200 as long as the unlocking requirements are met and there is an installation space.

[0071] As Figure 3 shown, two transmission limit blocks 111 are provided on both sides of the vertical direction Y of the elastic deformation direction X of the elastic drive arm 109, and the elastic drive arm 109 is slidably engaged with the two transmission limit blocks 111 along its elastic deformation direction X. The elastic drive arm 109 is limited in the vertical direction Y of its elastic deformation direction X by the two transmission limit blocks 111, so as to prevent the elastic drive arm 109 from shaking in the vertical direction of its elastic deformation direction and causing fracture.

[0072] As Figure 1 , Figure 2 and Figure 3As shown in the figure, in the embodiment of the present invention, the number of the first male buckle structures 101, the first female buckle structures 103 and the transmission structures 105 is multiple, and they are arranged in one-to-one correspondence. The multiple first male buckle structures 101 are arranged at intervals around the unlocking structure 104, and are connected to the first component 200 through the multiple transmission structures 105. An unlocking channel 112 is formed between the multiple transmission structures 105 and is tapered along the pushing direction of the unlocking structure 104. The unlocking structure 104 can push the multiple transmission structures 105 to expand radially outward D along the unlocking channel 112 along the axial direction F of the unlocking channel 112. The multiple transmission structures 105 drive the first buckling protrusions 102 on the multiple first male buckle structures 101 to move radially inward along the unlocking channel 112 (i.e., the unlocking direction B of the first buckling protrusions 102) to release the buckling with the multiple first female buckle structures 103 to form an unlocking state. By buckling the first buckling protrusions 102 on the multiple first male buckle structures 101 along their buckling direction A with the multiple first female buckle structures 103, the reliability of the locking mechanism in the locked state is further improved, and the first component 200 and the second component 300 are locked and fixed. By providing the unlocking channel 112, the multiple transmission structures 105 can move radially outward D along the unlocking channel 112 simultaneously under the push of the unlocking structure 104, so as to drive the multiple first buckling protrusions 102 to move radially inward along the unlocking channel 112 simultaneously to achieve unlocking.

[0073] As Figure 3 shown, specifically, the number of the first buckling protrusions 102, the elastic buckling arms 106, the bending arms 107 and the elastic transmission arms 109 is two, and they are symmetrically arranged with respect to the axis of the unlocking channel 112. The inner wall surface of the elastic transmission arm 109 facing the unlocking channel 112 is generally an arc surface structure, so that it has better elastic expansion ability radially outward along the unlocking channel 112. The thickness of the elastic transmission arm 109 is not specifically limited and is designed according to the elastic requirements of the elastic transmission arm 109.

[0074] As Figure 1 shown, in the embodiment of the present invention, the unlocking structure 104 includes a driving member 113 and an unlocking rod 114. The driving member 113 is connected to the unlocking rod 114, and the driving member 113 is used to drive the unlocking rod 114 to move along the axial direction of the unlocking channel 112. By providing a driving force through the driving member 113, unlocking can be more easily achieved. Specifically, the driving member 113 is a micro motor. As Figure 4 and Figure 5 shown, a threaded hole 129 is provided along the axial direction of the unlocking rod 114, and the output shaft 134 of the driving member 113 is threadedly connected to the threaded hole 129. The unlocking rod 114 is driven into the unlocking channel 112 through screw transmission. As Figure 1 shown, the driving member 113 is installed and fixed on a component through a fixed angle plate 124. Combining Figure 6 andFigure 7 As shown, the fixed angle plate 124 is connected to the component through the first connecting plate 125 and is connected to the driving member 113 through the second connecting plate 126. A limiting sleeve 127 is provided on the second connecting plate 126, and a guiding hole 128 is provided on the limiting sleeve 127. The guiding hole 128 is a polygonal hole. The unlocking rod 114 has a mounting portion 131 that slidably cooperates with the guiding hole 128 and a pushing portion 130 that slidably cooperates with the unlocking limiting hole 116. By the cooperation of the mounting portion 131 and the guiding hole 128, the rotation of the unlocking rod 114 can be restricted and it can only move along its axial direction.

[0075] As Figure 1 and Figure 2 shown, specifically, the radial dimension of the larger end of the unlocking channel 112 is equal to the radial dimension of the unlocking rod 114. During the process of the unlocking rod 114 moving towards the unlocking channel 112, after the radial dimension of the unlocking channel 112 is smaller than the radial dimension of the unlocking rod 114, the unlocking rod 114 abuts against the inner arc surface of the elastic transmission arm 109 and continues to slide, thereby pushing the elastic transmission arm 109 to expand and deform outwards.

[0076] As Figure 2 and Figure 4 shown, in order to ensure that the unlocking rod 114 can accurately enter the unlocking channel 112, an unlocking limiting boss 115 is provided on the second component 300, an unlocking limiting hole 116 is provided on the unlocking limiting boss 115, an unlocking limiting groove 117 and an ejection hole 118 are provided on the first component 200. The unlocking limiting groove 117 cooperates with the unlocking limiting boss 115, and the unlocking limiting hole 116 is communicated with the unlocking channel 112 through the ejection hole 118. The unlocking rod 114 slidably cooperates with the unlocking limiting hole 116 along the axial direction of the unlocking channel 112.

[0077] As Figure 8 shown, the locking mechanism further includes an unlocking key 119, and the unlocking key 119 is electrically connected to the driving member 113 through a control module. Among them, the installation position of the unlocking key 119 is not specifically limited and can be installed on other components near the first component 200 or the second component 300. The control module can be the control module of the whole machine where the first component 200 and the second component 300 are located, or it can be an independent control module. After the unlocking key 119 is pressed, an unlocking instruction is generated, and the control module controls the driving member 113 to drive the unlocking rod 114 to unlock according to the unlocking instruction.

[0078] Specifically, the unlocking key 119 includes a touch switch 120 and a key housing 121. The touch switch 120 is a circuit board 123 with two elastic buttons 122. The touch switch 120 is equipped with a terminal block and can be electrically connected to the control module through a wire. Each time the unlocking key 119 is pressed, a signal is generated and transmitted to the control module, and the control module issues an unlocking instruction to the driving member 113 to start working. At the same time, the touch switch 120 has a rebound function. When the pressing stops, it will bounce back to its original position and no longer emit a signal until it is pressed and bounced again. The working principle of the unlocking key 119: When the key housing 121 is pressed, the pressure is transmitted to the two elastic buttons 122 on the touch switch 120, and the elastic buttons 122 are pressed down. The downward pressure is converted into an electrical signal by the touch switch 120 and transmitted to the control module through the wire connected to the touch switch 120. The control module issues an unlocking instruction to the driving member 113 according to the received signal, and the driving member 113 drives the unlocking rod 114 to push the transmission structure 105 to unlock according to the unlocking instruction. When the key housing 121 is released, the elastic buttons 122 of the touch switch 120 bounce back, and the bouncing force is transmitted to the key housing 121 covering the elastic buttons 122, and the key housing 121 bounces back synchronously. When the elastic buttons 122 bounce back, since the downward pressure disappears, the touch switch 120 no longer sends a signal to the control module, and the control module issues a reset instruction to the driving member 113. The driving member 113 drives the unlocking rod 114 back to the initial position according to this reset instruction until the unlocking key 119 is pressed again.

[0079] Embodiment 2

[0080] As Figure 9 and Figure 10 As shown, the present invention also provides a brewing chamber 400, including a locking mechanism 100. The brewing chamber 400 further includes a chamber lid 401 and a chamber body 402. The chamber lid 401 is locked and closed on the chamber body 402 through the locking mechanism 100. The specific structure, beneficial effects, and working principle of the locking mechanism 100 in this embodiment are the same as those of the locking mechanism in Embodiment 1 and will not be elaborated here. In the brewing chamber 400 of the present invention, the chamber lid 401 and the chamber body 402 are locked and fastened through the locking mechanism 100, which can design a large sealing pressure resistance between the chamber lid 401 and the chamber body 402, and the chamber lid 401 can be opened by unlocking the locking mechanism 100 through the unlocking structure 104. The operation is simple, so it can meet the pressure resistance requirements while avoiding the problem that the chamber lid 401 cannot be opened.

[0081] As Figure 13As shown, in the embodiments of the present invention, the bin cover 401 includes an inner cover 403 and an outer cover 404. The inner cover 403 and the outer cover 404 are butted and enclosed to form a cavity 428. The inner cover 403 serves as the first component 200, and the transmission structure 105 is located in the cavity 428. By installing the transmission structure 105 in the cavity 428 between the inner cover 403 and the outer cover 404, it is possible to prevent the user from accidentally touching and causing the bin cover 401 to open, and it is more aesthetically pleasing.

[0082] As Figure 10 shown, in the embodiments of the present invention, the outer cover 404 is locked and fastened to the bin body 402 through an outer locking mechanism 405. In the present invention, by cooperating the outer locking mechanism 405 with the locking mechanism 100, the outer cover 404 is fastened to the bin body 402 by the outer locking mechanism 405 to form the first pressure-resistant measure, and the inner cover 403 is fastened to the bin body 402 by the locking mechanism 100 to form the second pressure-resistant measure, further ensuring the pressure resistance of the brewing bin 400.

[0083] As Figure 9 、 Figure 13 and Figure 14 shown, the outer locking mechanism 405 includes: a transmission plate 406, which is hinged to the outer cover 404, and an elastic reset structure 407 is provided between the transmission plate 406 and the outer cover 404; at least one second male buckle structure 408, one end of the second male buckle structure 408 is provided with a second buckling protrusion 409, a second through hole 410 is provided on the inner cover 403, the second male buckle structure 408 is passed through the second through hole 410, and the second buckling protrusion 409 extends to the side of the inner cover 403 close to the bin body 402, and the other end of the second male buckle structure 408 is connected to the transmission plate 406; at least one second female buckle structure 411, which is provided on the bin body 402, and the second buckling protrusion 409 can move in its buckling direction to be buckled with the second female buckle structure 411 to form a locked state; wherein, the unlocking structure 104 can push open the transmission structure 105 and push the transmission plate 406 to rotate, and the transmission plate 406 can drive the second buckling protrusion 409 to move in its unlocking direction to release the buckle with the second female buckle structure 411 to form an unlocked state. After unlocking the locking mechanism 100 between the inner cover 403 and the bin body 402 by using the unlocking structure 104, then pushing the transmission plate 406 to unlock the outer locking mechanism 405 between the outer cover 404 and the bin body 402, the structure is compact, ensuring the pressure resistance of the brewing bin 400 while ensuring that the bin cover 401 is easy to open. Specifically, the elastic reset structure 407 is a reset spring 417. The second female buckle structure 411 includes a second buckle hole 412.

[0084] To make the technical solution of the present invention clearer, the structure of the brewing bin 400 will be described in more detail below.

[0085] As Figure 2 、 Figure 15 、Figure 16 , Figure 17 , Figure 18 as well as Figure 23 As shown, the structure of the inner cover 403, specifically, the inner cover 403 is used as the first component 200, and the first male buckle structure 101 is installed on the inner cover 403 through the transmission structure 105. The inner cover 403 is generally a U-shaped cover structure, and the outer edge of the inner cover 403 is provided with an L-shaped step to be connected with the inverted L-shaped step on the outer cover 404. There is a mounting groove 429 at the center position near the edge of the inner side surface of the inner cover 403 (i.e., the side opposite to the outer cover 404 and away from the bin body 402), which is used to install the transmission plate 406. There is a circular through hole at the center position of the mounting groove 429, which is the ejection hole 118 for the unlocking rod 114 to penetrate. The aperture of the ejection hole 118 is slightly larger than the diameter of the unlocking rod 114, so as to facilitate the ejection of the unlocking rod 114. Two elastic transmission arms 109 are arranged on the left and right sides of the ejection hole 118 and extend obliquely toward the inner side thereof. The inner arc surfaces of the two elastic transmission arms 109 are respectively arranged along the edge of the ejection hole 118 and extend obliquely toward the inner side thereof, and are arranged symmetrically with respect to the axis of the ejection hole 118, thereby forming an unlocking channel 112 that is gradually arranged along the pushing direction F of the unlocking rod 114. Two square holes are symmetrically distributed on both sides of the ejection hole 118, which are the first through holes 110 for passing the elastic buckle arms 106. An unlocking limit groove 117 is provided on the outer side surface of the inner cover 403 (i.e., the side opposite to the outer cover 404 and close to the bin body 402), and the ejection hole 118 is located at the center of the bottom of the unlocking limit groove 117, and the unlocking limit groove 117 constitutes the buckling groove of the unlocking limit boss 115. When the bin cover 401 is buckled onto the bin body 402, the upper half of the unlocking limit boss 115 abuts against the unlocking limit groove 117.

[0086] like Figure 19 and Figure 20 As shown, the structure of the outer cover 404 is specifically, the outer cover 404 is made of plastic material by an integral injection molding process. The outer cover 404 is an arched sheet structure with two parallel flanges, and the two flanges extend downward perpendicular to the arched surface. The bottom edges of the two flanges are respectively provided with an inverted L-shaped step to match and dock with the L-shaped step on the inner cover 403 of the bin cover 401. Figure 9 , Figure 11 as well as Figure 12 As shown, when the outer cover 404 is buckled into the opening of the shell 413 of the bin body 402, the surface of the outer cover 404 and the surface of the shell 413 are coplanar to form a continuous arc surface. A runway-shaped through hole is provided near the short side of the outer cover 404 and at the center of its extension direction, which is the button mounting hole 426 of the unlocking button 119 (i.e., the opening button of the bin cover 401). The button mounting hole 426 is arranged perpendicular to the arched surface of the outer cover 404. Figure 8As shown, the button mounting hole 426 matches the size of the button housing 121, facilitating the installation of the button housing 121. There is an annular arc surface with equal width connecting between the button mounting hole 426 and the outer side wall of the outer cover 404. This arc surface is slightly recessed relative to the surface of the outer cover 404 to improve the comfort when the finger presses the button housing 121. The edge of the button housing 121 extends outward to form a mounting edge 135, and the mounting edge 135 is generally in the shape of a runway. When the button housing 121 is inserted into the button mounting hole 426 on the outer cover 404 from the inside of the outer cover 404, the button housing 121 passes through the button mounting hole 426, and the mounting edge 135 is located inside the outer cover 404, so that the button housing 121 is limited by the mounting edge 135 and coplanar with the outer side surface of the outer cover 404 (i.e., the side opposite to the inner cover 403). The two ends in the length direction of the touch switch 120 are connected to two mounting posts 432 on the inner side surface of the outer cover 404 by screws. The two elastic buttons 122 on the touch switch 120 are symmetrically arranged with respect to the center of the circuit board 123, and are located on the center line in the length direction of the button mounting hole 426 on the outer cover 404 after installation. The elastic button 122 extends into the groove of the button housing 121 and abuts against the button housing 121.

[0087] As Figure 13 , Figure 15 and Figure 20 shown, for the installation of the outer locking mechanism 405, specifically, a first spring mounting post 418 is provided on the inner side of the outer cover 404 (i.e., the side close to the inner cover 403). The first spring mounting post 418 is arranged close to the long side of the button mounting hole 426 and is located at the central position in the extending direction of the short side of the outer cover 404. One end of the return spring 417 is sleeved on the first spring mounting post 418, and the other end of the return spring 417 is sleeved on the second spring mounting post 419 on the transmission plate 406. The first spring mounting post 418 and the second spring mounting post 419 are arranged opposite to each other and coaxially. The radial dimensions of the first spring mounting post 418 and the second spring mounting post 419 are equal, and the return spring 417 is coaxially arranged with the first spring mounting post 418 and the second spring mounting post 419 after installation. After the outer cover 404 and the inner cover 403 are installed, there is a certain gap between the first spring mounting post 418 and the second spring mounting post 419 to form an elastic deformation space for the return spring 417. The two ends of the return spring 417 are in a natural straight state (i.e., a free state without extrusion force and tensile force) after being sleeved on the first spring mounting post 418 and the second spring mounting post 419. Combining Figure 1 , Figure 9 and Figure 14As shown, when the drive plate 406 is pushed up by the unlocking lever 114 until the second engaging protrusion 409 disengages from the second engaging hole 412, the drive plate 406 can return to its original position by the rebound of the return spring 417; when the unlocking lever 114 does not push up the drive plate 406, the return spring 417 is in a free state; when the drive plate 406 is pushed up, the return spring 417 is in a compressed state; when continuously pushed up until the second engaging protrusion 409 disengages from the second engaging hole 412, the return spring 417 returns from the compressed state to the free state.

[0088] As Figure 9 , Figure 11 , Figure 12 and Figure 23 As shown, for the structure of the bin body 402, specifically, the bin body 402 has a housing 413, and inside the housing 413, there is a top plate 414, a bottom plate 415 and four side plates 416. As Figure 24 shown, the four side plates 416 are vertically arranged on the bottom plate 415 and enclose to form an installation space 431. The top plate 414 is installed on the four side plates 416 and is connected to the crescent-shaped flanging 433 at the opening of the housing 413. The top plate 414 is recessed towards the installation space 431 to form a bin chamber 427. The top plate 414 serves as the second component 300, and the first female fastener structure 103 and the unlocking limit boss 115 are provided on the top plate 414. Combining Figure 26 shown, the housing 413 of the bin body 402 is generally an arc-shaped shell, and the housing 413 is the outer shell of the entire brewing machine. The center of the top of the housing 413 has an arc-shaped rectangular notch, forming the fastening port 423 of the bin cover 401. In the fastened state, the surface of the outer cover 404 is coplanar with the outer arc surface of the housing 413.

[0089] As Figure 1 , Figure 5 , Figure 11 , Figure 12 , Figure 24 and Figure 25As shown, the structure and installation of the driving member 113. Specifically, the driving member 113 is installed on the outer side surface of a side plate 416 through a fixing angle plate 124 and is located below the top plate 414. The side surface of the driving member 113 is in contact with the outer side surface of the side plate 416. The size of the second connecting plate 126 matches the top surface of the driving member 113. When the output shaft 134 of the driving member 113 rotates, it drives the unlocking rod 114 to move axially along the polygonal guiding hole 128 of the limiting sleeve 127 through screw transmission, ensuring that the unlocking rod 114 can accurately enter the unlocking channel 112 and preventing the unlocking rod 114 from deviating due to vibration during movement and thus being unable to accurately enter the unlocking channel 112. A supporting groove 420 is provided on the bottom plate 415 for supporting the driving member 113. The driving member 113 has a main body portion 132 and a square column portion 133. There are two oppositely arranged mounting blocks 421 in the supporting groove 420. The mounting blocks 421 are perpendicular to the bottom plate 415, and the main body portion 132 of the driving member 113 is clamped between the inner arc surfaces of the two mounting blocks 421. The square column portion 133 of the driving member 113 abuts against the top surface of the mounting block 421. A wire groove 424 is provided between the bottom ends of the two mounting blocks 421 for leading out the wires of the driving member 113 and connecting them to the control module. A supporting block 422 is provided between the bottom ends of the two mounting blocks 421 for lifting the driving member 113, thereby preventing the vibration generated during the operation of the driving member 113 from being transmitted to other components and causing noise.

[0090] As Figure 5 and Figure 6As shown, the structure and installation of the unlocking lever 114. Specifically, the unlocking lever 114 includes an installation portion 131 and a pushing portion 130, and is generally in the shape of a hexagonal sleeve structure with a cylindrical rod-shaped body at the center of the top end. The installation portion 131 of the unlocking lever 114 is provided with a cylindrical threaded hole 129, and the bottom end of the threaded hole 129 has an opening. The threaded hole 129 is matched with the thread of the output shaft 134 of the driving member 113. When the driving member 113 works, the extension and retraction of the unlocking lever 114 are realized through the forward and reverse rotation of its output shaft 134. The top end of the pushing portion 130 of the unlocking lever 114 is provided with a tapered platform structure, which is convenient for jacking up the transmission plate 406. In the locked and closed state of the bin cover 401, the unlocking lever 114 is in the initial position and has not risen under the drive of the driving member 113. The top of the unlocking lever 114 is located in the unlocking limit hole 116 and never comes out, ensuring the limiting function of the limit hole. During the process of opening the bin cover 401, the output shaft 134 of the driving member 113 rotates forward, and the unlocking lever 114 continuously rises in the unlocking limit hole 116 until it jacks up the transmission plate 406 to a certain height. When the unlocking lever 114 rises to the set height, the transmission plate 406 is jacked up to the specified height, and the outer locking mechanism 405 is unlocked; then the output shaft 134 of the driving member 113 rotates reversely, and the unlocking lever 114 retracts to the initial position. When the unlocking lever 114 touches the transmission plate 406, the forward rotation of the output shaft 134 of the driving member 113 drives the unlocking lever 114 to gradually rise, the transmission plate 406 is rotated and turned up, and the turning angle becomes larger and larger, and the return spring 417 is continuously compressed.

[0091] As Figure 1 , Figure 13 , Figure 21 and Figure 22As shown in the figure, the structure of the outer locking mechanism 405 is specifically as follows: The transmission plate 406 is generally in a plate-like structure with a flipping shaft 430. When the unlocking lever 114 jacks up the transmission plate 406, the transmission plate 406 can rotate and flip up along the flipping shaft 430. The edge of the transmission plate 406 has an L-shaped groove to be embedded in the installation groove 429 on the inner side surface of the inner cover 403. The transmission plate 406 continuously rotates and flips up under the jacking force of the unlocking lever 114, the elastic deformation space of the return spring 417 shrinks, and the return spring 417 is continuously compressed until the outer locking mechanism 405 is unlocked, the unlocking lever 114 no longer rises, the jacking force on the transmission plate 406 disappears, and the transmission plate 406 is bounced back to its original position under the elastic restoring force of the return spring 417. A jacking groove 425 is provided on the side surface of the transmission plate 406 opposite to the inner cover 403 to accommodate the first male buckle structure 101 and the transmission structure 105. The top end of the elastic transmission arm 109 and the bending arm 107 are parallel to the bottom surface of the jacking groove 425 and have a certain gap, so that it will not interfere with the elastic deformation of the elastic transmission arm 109. The jacking groove 425 is coaxial with the unlocking channel 112. The length of the jacking groove 425 is greater than or equal to the distance between the side walls of the two first through holes 110 that are far away from each other, so as to avoid interfering with the elastic deformation of the elastic buckle arm 106.

[0092] As Figures 1 to 26 shown, the specific working process of the present invention is as follows:

[0093] Latching of the chamber lid 401: After placing the beverage capsule to be brewed in the chamber 427 and then covering the chamber lid 401, manually press down the chamber lid 401. At this time, the inclined plane of the first latching protrusion 102 abuts against the upper edge of the first latching hole 108. As the downward pressure continues to be applied, the inclined plane slides along its slope direction against the upper edge of the first latching hole 108, and the elastic buckle arm 106 is squeezed and elastically deformed into the first latching hole 108 until the first latching protrusion 102 slides into the first latching hole 108. Then, continue to apply a downward pressure to the chamber lid 401, and the first latching protrusion 102 abuts against the inner wall surface of the first latching hole 108 and slides downward. During the sliding process, the elastic buckle arm 106 is still in an elastically deformed state until the first latching protrusion 102 slides out of the first latching hole 108, the elastic deformation of the elastic buckle arm 106 disappears and returns to its natural state, so that the first latching protrusion 102 moves in its latching direction to below the lower edge of the first latching hole 108, and the first latching protrusion 102 is latched in place, thus locking the entire chamber lid 401, and at the same time the outer locking mechanism 405 is also in a locked state, completing the locking and covering of the chamber lid 401.

[0094] When brewing a beverage capsule, the pressure in the chamber 427 increases. The chamber lid 401 is under the action of this pressure and tends to be pushed outwards. As a result, the first fastening protrusion 102 abuts against the plane around the lower edge of the first fastening hole 108. Due to the counterforce generated by the abutment of the first fastening protrusion 102, the chamber lid 401 cannot be pushed open by the pressure in the chamber 427, thus protecting the sealed fastening of the chamber lid 401 and improving the pressure resistance of the entire brewing chamber 400.

[0095] Opening of the chamber lid 401: When the brewing of the beverage capsule is completed, manually press the open lid button (i.e., the unlocking button 119) to achieve automatic opening of the lid. The pressing force is transmitted through the button housing 121 to the touch switch 120 below. The elastic button 122 on the touch switch 120 is pressed down. The downward force is converted into an electrical signal by the circuit board 123 of the touch switch 120 and transmitted to the brewing machine control module via the wire connected to the touch switch 120. After receiving the signal, the control module issues an open lid command (i.e., an unlocking command) to the driving member 113. The driving member 113 rotates its output shaft 134 forward according to this open lid command. Thus, under the action of the screw engagement drive, the unlocking lever 114 moves upward, and then extends into the unlocking channel 112 to push the elastic transmission arm 109. As the unlocking lever 114 slides upward against the inner arc surface of the elastic transmission arm 109, it pushes the elastic transmission arm 109 to expand elastically outwards, and drives the first fastening protrusion 102 to move inwards from the periphery of the lower edge of the first fastening hole 108 through the bending arm 107 and the elastic fastening arm 106 to release the fastening. The output shaft 134 of the driving member 113 continues to rotate forward, causing the unlocking lever 114 to continue to rise and pass through the unlocking channel 112 to abut against the transmission plate 406, and continue to rise. As a result, the transmission plate 406 rotates and flips up under the upward pushing force of the unlocking lever 114, and the flipping angle becomes larger and larger. The return spring 417 is continuously compressed. Until the unlocking lever 114 rises to a specified height, the second fastening protrusion 409 is released from the fastening, and the unlocking lever 114 stops rising. The upward pushing force acting on the transmission plate 406 disappears. The return spring 417 returns from the compressed state to the free state. The transmission plate 406 is pushed by the elastic restoring force of the return spring 417 from the compressed state to the free state and returns to the normal state. The chamber lid 401 opens. The control module automatically controls the output shaft 134 of the driving member 113 to reverse according to the set control program. That is, the trigger condition for the output shaft 134 of the driving member 113 to reverse is that the unlocking lever 114 extends a set stroke. This set stroke has been written into the control program of the control module in advance. Once the condition is met, the control module automatically controls the output shaft 134 of the driving member 113 to reverse, and then drives the unlocking lever 114 to retract to the initial position under the guidance of the unlocking limit hole 116 through the screw drive, completing the opening of the chamber lid 401.
