Technical Field

[0001] The utility model relates to the technical field of beverage equipment, in particular to a beverage machine. Background Art

[0002] With the popularity of beverage machines, especially coffee machines, in daily life, users have put forward higher requirements for the user experience, functional integration and operational convenience of beverage machines. Today's beverage machines (such as coffee machines) usually include a body with an opening and a door body that can open or close the opening. The door body is usually integrated with an operating interface, such as a display screen, which is used to display the status of the beverage machine for users to view and for users to control the operation of the beverage machine. Among them, a locking mechanism is usually required between the door body and the body of the beverage machine to ensure that the door body can be reliably opened and closed, and to keep the door body in a stable locked state when the beverage machine is not in use.

[0003] However, the locking mechanism on traditional beverage machines has the following defects: complex structure, many parts, difficult assembly, prone to unreliable locking or difficult unlocking, especially after multiple uses, the reliability of the locking mechanism will be significantly reduced; in addition, when the existing locking mechanism is subjected to vibration or impact, the door body may automatically open due to unstable locking, triggering the door opening alarm, affecting the efficiency of beverage preparation. Utility Model Content

[0004] The purpose of the utility model is to provide a beverage machine.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a beverage machine, comprising a body having an opening, a door connected to the body to open or close the opening, and a locking mechanism for locking the body and the door, wherein the locking mechanism comprises:

[0006] a driving member, movably connected to the door body;

[0007] At least one locking member, movably connected to the door body, the locking member being drivingly connected to the driving member;

[0008] A locking portion, provided on the body;

[0009] One of the locking member and the driving member is provided with a sliding groove, and the other is provided with a slider that cooperates with the sliding groove. The driving member is configured to be rotatable to drive the slider and the sliding groove to move relative to each other. The relative movement of the slider and the sliding groove drives the locking member to move to a locked position or to an unlocked position. In the locked position, the locking member is limitedly connected to the locking portion, and in the unlocked position, the locking member and the locking portion are released from the limited connection.

[0010] The beverage machine in the present invention realizes the driving connection between the driving member and the locking member through the sliding groove and the slider in the locking mechanism. Only the driving member and the locking member are required to realize the function of locking the door body, which simplifies the structure of the locking mechanism and reduces the cost of production and maintenance. At the same time, the door body can only be opened when the driving member is operated, preventing the door body from being accidentally opened due to external force or misoperation, and can prevent unrelated personnel from operating, thereby improving safety performance.

[0011] As a further improved technical solution of the present invention, the slide groove is provided on the driving member, the slider is provided on one end of the locking member close to the driving portion, and the slider is constructed in a cylindrical shape adapted to the slide groove.

[0012] As a further improved technical solution of the present invention, the sliding groove is constructed as an elliptical groove arranged around the rotation center of the driving member. When the slider is located at the short axis position of the elliptical groove, the locking member is located at the unlocking position; when the slider is located at the long axis position of the elliptical groove, the locking member is located at the locking position.

[0013] As a further improved technical solution of the present invention, the sliding groove is constructed as a straight groove, one end of the straight groove is close to the rotation center of the driving member, and the other end of the straight groove is away from the rotation center of the driving member; the straight groove has a first position and a second position, and the distance between the first position and the one end is smaller than the distance between the second position and the one end; when the slider is at the first position, the locking member is at the unlocking position; when the slider is at the second position, the locking member is at the locking position.

[0014] As a further improved technical solution of the present invention, the locking mechanism includes two locking members, which are arranged on opposite sides of the driving member. The two locking members are configured to move linearly in opposite directions to the locking position or linearly in opposite directions to the unlocking position under the drive of the driving member. This can improve the locking effect of the locking mechanism.

[0015] As a further improved technical solution of the present invention, the locking mechanism also includes a pre-locking structure for pre-locking the machine body and the door body, the pre-locking structure includes a hook protruding from the door body toward the machine body, and a slot provided on the machine body, a block cooperating with the hook is provided in the slot, and the block is provided with guiding inclined surfaces for guiding the hook to enter and exit the slot respectively.

[0016] For the pre-locking structure, the user only needs to apply external force to the door with one hand to lock and unlock the door body. The operation is relatively simple, and the door body will not open by itself. When closing the door body, the pre-locking structure is first used to pre-lock the door body so that the door body closes the opening. The driving member can be operated to drive the locking member to cooperate with the locking part to completely lock the door body without holding the door body, which is convenient for the user to operate. At the same time, due to the heavy weight of the door body, when there is no external force interference between the door body and the machine body, one side of the door body is easily automatically rotated and opened due to the influence of gravity. In the utility model, by setting a pre-locking structure, the door body can be pre-locked only by operating the relatively simple pre-locking structure during maintenance, which is convenient for maintenance personnel to operate the door body with one hand. The operation is simple and labor-saving, and there is no need to repeatedly operate the driving member to lock or unlock the door body.

[0017] As a further improved technical solution of the present invention, the pre-locking structure further includes a reset member acting on the hook, and the reset member provides the hook with an engaging force to engage with the locking block.

[0018] As a further improved technical solution of the present invention, the locking mechanism also includes a base body fixed to the door body, and a cover body cooperating with the base body to enclose an installation cavity, and the locking member and the hook are at least partially movably accommodated in the installation cavity; a limiting structure is provided in the installation cavity, and the limiting structure is used to limit the installation position of the locking member and / or the hook.

[0019] As a further improved technical solution of the present invention, the locking mechanism also includes a pre-locking structure for pre-locking the machine body and the door body; the pre-locking structure is constructed as a magnetic attraction structure arranged between the machine body and the door body, and the magnetic attraction structure includes a first magnetic part arranged on the machine body and a second magnetic part arranged on the door body.

[0020] As a further improved technical solution of the present invention, the door body includes a mounting bracket and a display control screen arranged on the mounting bracket; the mounting bracket has a first end and a second end relative to each other, the first end is rotatably connected to the body, and the second end is limitedly connected to the body or releases the limit connection through the locking mechanism.

[0034] The following will describe the present invention in detail with reference to the embodiments shown in the accompanying drawings. Figures 1 to 13 The following are preferred embodiments of the present invention. However, it should be noted that these embodiments do not limit the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by persons skilled in the art based on these embodiments fall within the scope of protection of the present invention.

[0035] The terms used in this utility model to express position and direction are based on the beverage dispenser being placed on a support surface and in use. The side of the beverage dispenser facing the operator is defined as the front side of the beverage dispenser, and the side of the beverage dispenser away from the operator is defined as the rear side. The direction toward the direction of gravity of the beverage dispenser is defined as "downward," and the direction opposite to the direction of gravity of the beverage dispenser is defined as "upward." Furthermore, the terms "first," "second," etc., used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features indicated.

[0036] Please refer to Figures 1 to 13 As shown, the utility model provides a beverage machine, which is used for users to prepare target beverages.

[0037] The following is a detailed description of a beverage machine that prepares coffee, but it should be noted that the technical spirit involved in the following embodiments can be applied to beverage machines that prepare beverages other than coffee.

[0038] Combine Figures 1 to 8 As shown, the coffee machine 100 includes a body 1 having an opening and a door 2 connected to the body 1 to open or close the opening. When the door 2 is closed, it protects the components within the body 1 from the external environment and maintains the overall neatness and aesthetics of the coffee machine 100. When the door 2 is open, the user can access the components within the body 1 through the opening, such as cleaning, maintenance, and repairs, making operation more convenient.

[0039] In this embodiment, the door body 2 includes a mounting bracket 22 and a display screen 21 mounted on the mounting bracket 22. Specifically, the mounting bracket 22 has a mounting hole 221 for mounting the display screen 21, and a sidewall extending from the side of the mounting hole 221 in a direction away from the display screen 21. The end of the sidewall away from the display screen 21 cooperates with the body 1 to open or close the opening on the body 1.

[0040] The mounting bracket 22 has a first end and a second end that are opposite each other, with the first end being rotatably connected to the body 1. The beverage dispenser further includes a locking mechanism 3 for locking the body 1 and the door 2. In an embodiment in which the first end is rotatably connected to the body 1, the locking mechanism 3 is disposed at the second end. That is, the second end of the mounting bracket 22 is either limitatively connected to the body 1 or releaseably connected to the body 1 via the locking mechanism 3. When the second end is limitatively connected to the body 1, the opening of the body 1 is closed; when the second end is releaseably connected to the body 1, the opening of the body 1 can be opened by rotating the second end of the door 2.

[0041] Specifically, the sidewalls include a first sidewall 222 at a first end and a second sidewall 223 at a second end. The first and second sidewalls 222 and 223 extend from the display screen 21 toward the housing 1, i.e., from front to back. The first sidewall 222 is rotatably connected to the housing 1. A locking mechanism 3 is provided on the side of the second sidewall 223 facing the first sidewall 222, thereby locking or unlocking the door 2 at the end of the second sidewall 223.

[0042] In one embodiment, the first end and the second end are left and right ends, that is, the first side wall 222 and the second side wall 223 are two side walls located in the left and right directions. In this case, the door body 2 is a left-right rotating door body. Of course, this is not limited to this. For example, the door body 2 can also be a vertically rotating door body.

[0043] The locking mechanism 3 includes a driving member 31 movably connected to the door body 2, a locking member 32 movably connected to the door body 2 and drivingly connected to the driving member 31, and a locking portion 33 provided on the body 1. The locking portion 33 is used to cooperate with the locking member 32 to lock the door body 2. At least one locking member 32 is provided.

[0044] One of the locking member 32 and the driving member 31 is provided with a slide groove 3111, and the other is provided with a slider 321 that cooperates with the slide groove 3111. The driving member 31 is configured to be rotatable to drive the slider 321 and the slide groove 3111 to move relative to each other. The relative movement of the slider 321 and the slide groove 3111 drives the locking member 32 to move to a locked position or an unlocked position. When the locking member 32 is in the locked position, the locking member 32 and the locking portion 33 are limitedly connected to each other so that the second end of the door body 2 is limitedly connected to the machine body 1, that is, the second end of the door body 2 and the machine body 1 are locked to each other. When the locking member 32 is in the unlocked position, the locking member 32 and the locking portion 33 are released from the limited connection, so that the second end of the door body 2 can be separated from the machine body 1, that is, the opening can be opened by rotating the second end of the door body 2. In the present invention, the driving connection between the locking member 32 and the driving member 31 is realized by the matching structure of the slider 321 and the slide groove 3111. Only the driving member 31 and the locking member 32 are required to realize the function of locking the door body 2, which simplifies the structure of the locking mechanism 3 and reduces the production and maintenance costs. At the same time, the door body 2 can be opened only when the driving member 31 is driven, preventing the door body 2 from being accidentally opened due to external force or misoperation, preventing unrelated personnel from operating, and improving safety performance.

[0045] In some optional embodiments, an installation cavity 37 is provided in the door body 2. Specifically, the locking mechanism 3 includes a base body 34 fixed to the door body 2 and a cover body 35 cooperating with the base body 34 to enclose the installation cavity 37. The base body 34 is connected to the second side wall 223. By setting the locking mechanism 3 to have a installation cavity 37, the driving member 31 and the locking member 32 can be fixed to the installation cavity 37 through the cover body 35 to form an integral locking mechanism 3, and then the assembled locking mechanism 3 can be directly connected to the door body 2, so that the locking mechanism 3 is modularly arranged, thereby simplifying the assembly between the locking mechanism 3 and the door body 2.

[0046] In one embodiment, the locking member 32 is at least partially movably accommodated in the mounting cavity 37, the locking portion 33 is a lock hole, and the locking member 32 is configured to be movable between an unlocked position located inside the mounting cavity 37 and a locked position partially protruding outside the mounting cavity 37. That is, the driving member 31 is configured to be operable to rotate and drive the locking member 32 to move into the mounting cavity 37 to the unlocked position or to move out of the mounting cavity 37 to the locked position. After the user closes the door body 2, the locking portion 33 and the locking member 32 are in corresponding positions. At this time, the driving member 31 only needs to be rotated to drive the locking member 32 to move out of the mounting cavity 37 so as to protrude out of the mounting cavity 37 and insert into the lock hole, thereby locking the door body 2 and the machine body 1. When it is necessary to open the door body 2, the driving member 31 only needs to be rotated in the opposite direction to drive the locking member 32 to move into the mounting cavity 37 and disengage the lock hole, thereby unlocking the door body 2 and the machine body 1. The locking mechanism 3 has a simple structure and is easy to operate.

[0047] The outside of the above-mentioned mounting cavity 37 refers to the side of the base body 34 and / or the cover body 35 facing away from the mounting cavity 37. It can also be understood that the movement of the above-mentioned locking member 32 toward the outside of the mounting cavity 37 means that the locking member 32 moves away from the driving member 31, and the movement of the above-mentioned locking member 32 into the mounting cavity 37 means that it moves toward the driving member 31.

[0048] Combine Figure 3 、 Figure 6 As shown, in a specific embodiment in which the door body 2 is a left-right rotating door body, the locking mechanism 3 is configured to drive the locking member 32 to move up and down by rotating the driving member 31 .

[0049] In some optional embodiments, the locking mechanism 3 includes two locking members 32, and the two locking members 32 are arranged on opposite sides of the driving member 31; the two locking members 32 are arranged to be able to move linearly in opposite directions to the locking position or move linearly towards each other to the unlocking position under the drive of the driving member 31. Improve the locking effect of the locking mechanism 3. In the embodiment in which the locking mechanism 3 is arranged to drive the locking members 32 to move up and down by rotating the driving member 31, the two locking members 32 are respectively arranged on the upper and lower sides of the driving member 31. Among them, the linear movement in opposite directions specifically refers to the linear movement of the two locking members 32 away from each other, and the linear movement towards each other specifically refers to the linear movement of the two locking members 32 towards each other. In this embodiment, the linear movement specifically refers to the locking members 32 moving only in the up and down directions, without movement in the front-back direction and the left-right direction.

[0050] Specifically, the base body 34 includes a first wall 341 disposed opposite the second side wall 223, an upper wall 342 connected to the upper end of the first wall 341, a lower wall 343 located below the first wall 341, and a rear wall 344 located at the rear end of the first wall 341. A through-hole a is formed through the upper wall 342 and / or the lower wall 343 corresponding to the locking member 32, and the through-hole a is used to allow the corresponding locking member 32 to protrude outside the mounting cavity 37.

[0051] In some optional embodiments, the rear wall 344 is provided with a fixing hole 3441 protruding forward, and the second side wall 223 is provided with a fixing frame 2232 that cooperates with the fixing hole 3441. The fixing frame 2232 is provided with a fastening hole 2233. The fastener passes through the fixing hole 3441 and the corresponding fastening hole 2233 at the same time to achieve a fixed connection between the locking mechanism 3 and the door body 2, which is easy to operate.

[0052] For details, please refer to Figure 6 The locking member 32 and the cover body 35 are provided with a making way portion b for the fixing frame 2232 to avoid interference between the locking member 32 and the fixing frame 2232.

[0053] In this embodiment, the chute 3111 is provided on the driving member 31, and the slider 321 is provided on the end of the locking member 32 close to the driving member 31. The slider 321 is constructed in a cylindrical shape that is compatible with the chute 3111. In this case, the slider 321 can rotate in the chute 3111, and can also slide in the chute 3111 along the extension direction of the chute 3111. Constructing the slider 321 in a cylindrical shape that is compatible with the chute 3111 can ensure the smooth movement of the slider 321 in the chute 3111 and improve the operating feel. Specifically, sliding means that the size of the chute 3111 matches the diameter of the slider 321, and the slider 321 only moves in the chute 3111 along the extension direction of the chute 3111. Of course, this is not limited to this. In other embodiments, the chute 3111 can also be provided on the end of the locking member 32 close to the driving member 31, and the slider 321 is provided on the driving member 31.

[0054] Combine Figure 4 、 Figure 6 and Figure 7 As shown, in a specific embodiment in which the slide groove 3111 is provided on the driving member 31, the slide groove 3111 is constructed as an elliptical groove arranged around the rotation center of the driving member 31. The elliptical groove has a short axis and a long axis. When the slider 321 is located at the short axis position of the elliptical groove, the locking member 32 is located in the unlocked position. When the slider 321 is located at the long axis position of the elliptical groove, the locking member 32 is located in the locked position. When the driving member 31 rotates and drives the slider 321 from the short axis position to the long axis position, the slider 321 drives the locking member 32 to the locked position. When the driving member 31 rotates and drives the slider 321 from the long axis position to the short axis position, the slider 321 drives the locking member 32 to the unlocked position. In this embodiment, the slide groove 3111 is set to an elliptical groove, and the slider 321 is always located in the slide groove 3111 and slides, so that the cooperation between the slider 321 and the slide groove 3111 is relatively stable, and the operation feel is better. In the embodiment with two locking members 32, the two locking members 32 can be set to cooperate with the same elliptical groove, and the two locking members 32 can be directly set to be symmetrical relative to the rotation center of the driving member 31. The two locking members 32 extend less in the front and rear directions, thereby saving space and reducing the manufacturing cost of the locking members 32.

[0055] Specifically, the driving member 31 includes a driving portion 311 located within the mounting cavity 37, an operating portion 312 connected to the driving portion 311 and exposed to the outside of the door body 2, and a locking member 32 disposed within the mounting cavity 37. The locking member 32 is drivingly connected to the driving portion 311, i.e., the aforementioned slide 3111 is disposed on the driving portion 311. A user need only operate the operating portion 312 from outside the door body 2 to rotate the driving portion 311, thereby causing the slider 321 and the slide 3111 to move relative to each other, switching the locking member 32 between a locked position and an unlocked position. This simplifies operation. Furthermore, the door body 2 can only be opened by the user operating the operating portion, preventing the door body 2 from accidentally opening due to external force or misoperation, thereby preventing unauthorized personnel from operating the door, and improving safety.

[0056] Specifically, the driving portion 311 includes a base plate 3112. The operating portion 312 is disposed on a side of the base plate 3112 facing the second side wall 223. The slide groove 3111 is disposed on a side of the base plate 3112 facing away from the second side wall 223. The base plate 3112 includes an inner groove wall disposed around the rotation center of the driving portion 311, and an outer groove wall disposed on the periphery of the inner groove wall and spaced apart from the inner groove wall. The inner groove wall and the outer groove wall together form the slide groove 3111. The slider 321 protrudes toward the base plate 3112 to extend into the slide groove 3111.

[0057] In one embodiment, the operating portion 312 has a hexagonal groove 3121 , and the second side wall 223 has a window 2231 for exposing the operating portion 312 outward. The user can rotate the operating portion 312 using a hexagonal wrench that matches the hexagonal groove 3121 , facilitating operation.

[0058] In an embodiment where the operating portion 312 has a hexagonal groove 3121, the operating portion 312 can be configured not to protrude from the outside of the door body 2, which not only reduces the risk of the operating portion 312 being damaged by contact with objects other than the coffee machine 100, but also improves the appearance of the coffee machine 100.

[0059] In some optional embodiments, a limiting structure 4 is provided within the installation cavity. In one specific embodiment, the limiting structure 4 is configured to limit the installation position of the locking member 32, facilitating installation of the locking member 32 while allowing the locking member 32 to move only in a predetermined direction under the driving action of the driving member 31. Specifically, the limiting structure 4 limits the movement of the locking member 32 in the front-to-back direction, thereby facilitating installation of the cover 35, but does not limit the movement of the locking member 32 in the up-down direction, thereby allowing the locking member 32 to normally lock and unlock with the locking portion 33. Of course, this is not limiting; the limiting structure 4 can also be configured to limit the installation position of the driving member 31, facilitating installation of the driving member 31 while also facilitating stable rotation of the driving member 31 around its rotation center.

[0060] In a specific embodiment, the limiting structure 4 is a guiding rib provided on the seat body 34 , and the guiding rib can be integrally formed with the seat body 34 .

[0061] Combine Figure 9 and Figure 10 As shown, in another specific embodiment in which a slide groove 3111 is provided in the driving portion 311, this other specific embodiment differs from the other embodiments described above in that the slide groove 3111a is a straight groove, one end of which is close to the rotation center of the driving member 31, and the other end of which is away from the rotation center of the driving member 31. The straight groove has a first position and a second position, and the distance between the first position and the one end is smaller than the distance between the second position and the one end; that is, the first position is closer to the one end relative to the second position, and the second position is closer to the other end relative to the first position. In other words, the first position is closer to the rotation center relative to the second position. When the slider 321 is in the first position, the locking member 32 is in the unlocked position; when the slider 321 is in the second position, the locking member 32 is in the locked position.

[0062] When the driving member 31 rotates and drives the slide groove 3111a to rotate in the direction away from the locking portion 33, the slider 321 moves in the slide groove 3111a along the direction from the second position to the first position, thereby driving the locking member 32 to move to the inside of the installation cavity 37 to the unlocking position; when the driving member 31 rotates and drives the slide groove 3111a to rotate toward the locking portion 33, the slider 321 moves in the slide groove 3111a along the direction from the first position to the second position, thereby driving the locking member 32 to move to the outside of the installation cavity 37 to the locking position.

[0063] Specifically, in an embodiment where the sliding groove 3111a is a straight groove, the two locking members 32 correspond to the two straight grooves, and the two straight grooves are respectively provided on opposite sides of the rotation center of the driving portion 311. Thus, the driving portion 311 can synchronize the movement of the two locking members to the locked position or the unlocked position.

[0064] Except for the above-mentioned differences, the other specific embodiments of the present invention are the same as those of other embodiments, and are not described in detail here.

[0065] In some optional embodiments, the locking mechanism 3 also includes a pre-locking structure 36 for pre-locking the machine body 1 and the door body 2. The pre-locking structure 36 is configured to unlock the door body 2 when an external force is applied to the door body 2. That is, the locking effect achieved by the pre-locking structure 36 is weaker than that achieved by the locking member 32, and the door body 2 and the machine body 1 cannot be completely locked firmly. For the pre-locking structure 36, the user only needs to apply external force to the door body 2 with one hand to lock and unlock the door body 2. The operation is relatively simple, and the door body 2 will not open by itself. When closing the door body 2, the door body 2 is pre-locked by the pre-locking structure 36 first, so that the door body 2 closes the opening. The driving member 31 can be operated to drive the locking member 32 to cooperate with the locking part 33 to completely lock the door body 2 without holding the door body 2, which is convenient for user operation. At the same time, due to the heavy weight of the door body 2, when there is no external force interference between the door body 2 and the machine body 1, one side of the door body 2 is easily automatically rotated open due to the influence of gravity. In the utility model, a pre-locking structure 36 is provided. During maintenance, the door body 2 can be pre-locked only by operating the relatively simple pre-locking structure 36, which is convenient for maintenance personnel to operate the opening and closing of the door body 2 with one hand. The operation is simple and labor-saving, and there is no need to repeatedly operate the driving member 31 to lock or unlock the door body 2.

[0066] Combine Figure 11 and 12As shown, in a specific embodiment of the present invention, the pre-locking structure 36 includes a hook 361 protruding from the door body 2 toward the body 1, a slot 362 provided in the body 1, a block 3621 provided in the slot 362 for cooperating with the hook 361, and at least the block 3621 of the hook 361 and the block 3621 is provided with a guide slope c for respectively guiding the hook 361 into and out of the slot 362. The angle between the guide slope c on the side of the block 3621 closer to the body 1 and the horizontal plane is greater than the angle between the guide slope c on the side farther from the body 1 and the horizontal plane. Thus, when closing the door body 2, the closing process of the door body 2 is more labor-saving and smooth. After the door body 2 is closed, the pre-locking of the door body 2 with the body 1 is more reliable, and the door body 2 will not open on its own.

[0067] In some optional embodiments, combined with Figure 6 As shown, the hook 361 includes a hook body 3611 located outside the mounting cavity 37, a connecting block 3612 connected to the hook body 3611 and located within the mounting cavity 37, and the pre-locking structure 36 further includes a reset member 363 located within the mounting cavity 37 and acting on the connecting block 3612. The reset member 363 provides an engaging force for the hook 361 to engage with the locking block 3621. As the hook 361 moves in and out of the slot 362, the reset member 363 is pressed by the guiding slope c. After the hook 361 moves past the locking block 3621, the elastic restoring force of the reset member 363 resets the hook 361 to engage with or disengage from the locking block 3621.

[0068] Specifically, the rear wall 344 is provided with a through hole 3442 for the hook 361 to pass through and move.

[0069] In a specific embodiment, combined with Figure 6 、 Figure 8 As shown, the reset member 363 is a spring, and a stopper 351 is protruding from the cover 35 or the base 34. One end of the spring abuts against the connecting block 3612, and the other end abuts against the stopper 351. Since the stopper 351 is fixed and the connecting block 3612 is movable, when the hook 361 enters and exits the slot 362, the hook 361 moves upward under the action of the guiding slope c, causing the lower end of the connecting block 3612 to press the reset member 363 upward. After the hook 361 moves past the block 3621, the force of the reset member 363 drives the hook 361 downward, thereby achieving mutual engagement or disengagement between the hook 361 and the block 3621. Of course, this is not limiting, and in other embodiments, the reset member can also be configured as a torsion spring or other structures.

[0070] In one embodiment, the pre-locking structure 36 includes at least two hooks 361 spaced apart in the vertical direction, and a slot 362 provided on the body 1 and corresponding one-to-one with the hooks 361, thereby improving the reliability of the pre-locking of the locking mechanism 3. In one embodiment having at least two hooks 361 and a reset member 363, the at least two hooks 361 can be configured as an integral structure, that is, the connecting block 3612 of the at least two hooks 361 is an integral structure, and the two hooks 361 are integrally connected via the connecting block 3612. As a result, only one reset member 363 is required, simplifying the structure of the locking mechanism 3.

[0071] Specifically, in an embodiment where the pre-locking structure 36 includes a hook 361 protruding from the side of the door body 2 toward the body 1, the connecting block 3612 can be set to be supported on the forward-protruding fixing hole 3441 on the above-mentioned rear wall 344, which can prevent the hook 361 from being damaged by being subjected to force alone, thereby improving the stability of the locking mechanism 3.

[0072] In this embodiment, the driving member 31 and the locking member 32 are disposed on the front side of the connecting block 3621. The hook 361 is at least partially movably accommodated within the mounting cavity 37. The limiting structure 4 disposed within the mounting cavity 37 can also be configured to limit the installation position of the hook 361, that is, the installation position of the connecting block 3621. Specifically, the limiting structure 4, the locking member 32, and the hook 361 are sequentially disposed along the front-to-back direction. The limiting structure 4 and the locking member 32 restrict the front-to-back movement of the hook 361, thereby facilitating the installation of the cover 35. However, the vertical movement of the hook 361 is not restricted, thereby allowing the hook 361 to properly lock and unlock with the slot 362. Thus, the locking member 32 and the limiting structure 4 can directly limit the hook 361, eliminating the need for additional structure to limit the hook 361. This simplifies the structure and reduces costs. Furthermore, the locking member 32 can guide the movement of the hook 361, facilitating stable engagement between the hook 361 and the block 3621.

[0073] Combine Figure 13 As shown, in another embodiment of the present invention, the difference between this embodiment and the above embodiment is that the pre-locking structure 36b is constructed as a magnetic attraction structure provided between the machine body 1 and the door body 2. The structure is simple and easy to operate.

[0074] Specifically, the magnetic structure includes a first magnetic member 365 provided on the body 1 and a second magnetic member 364 provided on the door body 2; when the door body 2 is closed, the first magnetic member 365 is magnetically connected to the second magnetic member 364.

[0075] Except for the above differences, the other embodiments of the present invention are the same as those of the other embodiments, and will not be described in detail here.

[0076] Compared with the prior art, the beverage machine in the present invention simplifies the locking mechanism by realizing the driving connection between the driving member 31 and the locking member 32 through the slide groove 3111 and the slider 321 in the locking mechanism 3, and is easy to operate. At the same time, the door body 2 can only be opened by the user operating the operating part 312, preventing the door body 2 from being accidentally opened due to external force or misoperation, and preventing unrelated personnel from operating, thereby improving safety performance.
