Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to an electrical box assembly, an electrical box assembly fixing structure, and a coffee machine. Background Technology

[0002] In existing technologies, the electrical enclosure of coffee machines lacks a programming space and a structure that allows this space to be opened or closed, which significantly negatively impacts the maintenance, protection, and long-term operation of the coffee machine. First, when it's necessary to update coffee extraction parameters, optimize the heating program, or fix circuit program vulnerabilities, the lack of a dedicated programming space necessitates disassembling the entire electrical enclosure or even the main body of the coffee machine to access the circuit board programming components, drastically increasing maintenance time. Second, the absence of a sealed switch structure leaves the programming openings permanently exposed, or requires destructive operation to open the electrical enclosure. The former allows coffee grounds and steam condensation to continuously infiltrate the enclosure, causing short circuits and component corrosion, while the latter damages the original protective system of the enclosure, exacerbating the risk of circuit failure. Utility Model Content

[0003] Therefore, it is necessary to address the problem that the electrical box assembly of a coffee machine lacks a programming space and a structure that allows the programming space to be opened or closed, by providing an electrical box assembly, an electrical box assembly fixing structure, and a coffee machine.

[0004] An electrical box assembly includes: a mounting housing having a programming space; a cover assembly disposed on the mounting housing and cooperating to form the programming space; a circuit board assembly disposed on the mounting housing and located in the programming space; and a sealing assembly detachably disposed on the mounting housing, a portion of the sealing assembly located in the programming space, a portion of the circuit board assembly being opposite to the portion of the sealing assembly located in the programming space, and the sealing assembly being capable of opening or closing the programming space.

[0005] The above-disclosed electrical box assembly features a programming space within the mounting housing that works in conjunction with a detachable sealing component. During daily use of the coffee machine, when programming the circuit board assembly to update coffee brewing parameters (such as extraction temperature and duration adjustments), the sealing component can be opened to directly expose the portion of the circuit board assembly located in the programming space, eliminating the need to disassemble the entire electrical box or even the coffee machine itself. This greatly simplifies the programming process, avoids affecting the sealing of the internal piping due to large-scale disassembly, and saves maintenance time and labor costs. Furthermore, after programming, the sealing component tightly closes the programming space, effectively preventing coffee powder, steam condensation, and external dust generated during coffee machine operation from entering the programming space. This prevents these impurities from adhering to critical parts of the circuit board assembly and causing short circuits, poor contact, and other malfunctions. Simultaneously, the mounting space formed by the sealing component and the mounting housing completely encloses the circuit board assembly, reducing interference from external environmental factors and lowering the probability of malfunctions.

[0006] In one embodiment, the sealing assembly includes a sealing base plate, a sealing body, and a limiting member. The sealing base plate is disposed on the mounting housing, the sealing body is disposed on the sealing base plate and abuts against the mounting housing, the sealing body passes through the burning space and extends into the mounting space, and the limiting member is disposed on the sealing base plate and abuts against the mounting housing. The mounting housing has a limiting space, and the limiting member passes through the limiting space and extends into the mounting space. By fixing the sealing base plate to the mounting housing, a stable mounting reference is provided for the sealing body and the limiting member, preventing displacement of the sealing components due to vibration during coffee machine operation and ensuring the reliability of the overall sealing structure. Simultaneously, its close fit with the mounting housing initially prevents coffee powder and moisture from seeping into the installation gaps, laying the foundation for subsequent sealing protection. The sealing body is not only disposed on the sealing base plate but also abuts against the mounting housing and extends through the burning space into the mounting space. This through-type design forms a tight seal at the burning space, effectively preventing coffee powder and steam condensation generated during coffee machine operation from entering the burning space and mounting space, thus preventing corrosion of the circuit board components. The limiting member passes through the limiting space of the mounting housing and extends into the mounting space. By abutting against the mounting housing, it further strengthens the connection between the sealing assembly and the mounting housing, preventing the sealing assembly from loosening and causing seal failure.

[0007] In one embodiment, the sealing body includes a sealing column and a sealing block. The sealing column is disposed on the sealing base plate and passes through the burning space. The sealing block is disposed on the sealing column and abuts against the mounting housing. The sealing block is located in the mounting space and is partially opposite to the circuit board assembly. By fixing one end of the sealing column to the sealing base plate and the other end passing through the burning space, a longitudinal sealing barrier can be formed within the burning space to prevent coffee powder and steam condensate generated during coffee machine operation from seeping into the mounting space along the longitudinal channel of the burning space, thus preventing corrosion of critical parts of the circuit board assembly. It also serves as a mounting carrier for the sealing block, providing stable support. The sealing block, located within the mounting space, abuts tightly against the mounting housing and can form a secondary seal through lateral compression, filling any tiny gaps that may exist between the sealing column and the mounting housing, strengthening the overall sealing effect, and preventing fine impurities from entering through the gaps. Furthermore, the sealing block firmly holds the sealing body in the burning space by the force generated by lateral compression, preventing the sealing body from shifting or loosening due to vibration during coffee machine operation, thus ensuring the continuity and reliability of the seal from a structural perspective.

[0008] In one embodiment, the limiting member includes a limiting post and a limiting block. The limiting post is disposed on the sealing base plate and passes through the limiting space. The limiting block is disposed on the limiting post and abuts against the mounting housing. The limiting block is located within the mounting space. By fixing one end of the limiting post to the sealing base plate and the other end passing through the limiting space of the mounting housing, it can provide additional support for the connection between the sealing component and the mounting housing through its own longitudinal structure, avoiding the uneven force problem that may occur when the sealing component is fixed solely by the sealing body. Furthermore, by adapting to the limiting space, it can accurately position the installation position of the sealing component, preventing the sealing component from shifting during installation or vibration during coffee machine operation, and ensuring the sealing performance between the sealing body and the burning space. The limiting block, located within the mounting space, abuts tightly against the mounting housing, further reinforcing the connection between the limiting post and the mounting housing through lateral clamping force. This forms a dual fixing structure of longitudinal support and lateral clamping, effectively resisting the vibration and impact during coffee machine operation and preventing the limiting member from loosening and causing the entire sealing component to shift.

[0009] In one embodiment, there are multiple limiting members, which are disposed on the sealing base plate and located on both sides of the sealing base plate. The sealing body is located between the multiple limiting members, and there are multiple limiting spaces, with each of the multiple limiting members corresponding to one of the multiple limiting spaces. By fixing multiple limiting members to both sides of the sealing base plate, symmetrical support can be formed from both ends of the sealing assembly, avoiding the unbalanced force of the sealing assembly when only one side is set. Especially when the coffee machine generates continuous vibration during operation, the limiting members on both sides can jointly disperse the vibration impact force, preventing the sealing assembly from tilting or shifting due to excessive force on one side, ensuring that the sealing body always accurately corresponds to the burning space and maintains a reliable seal. At the same time, the limiting members distributed on both sides and the sealing body in the middle form a synergistic structure of limiting on both sides plus sealing in the middle, making the overall force of the sealing assembly more uniform, improving the stability of the connection with the mounting housing, and reducing the risk of structural deformation after long-term use. In addition, multiple limiting components are installed one-to-one with multiple limiting spaces, which ensures that each limiting component can be accurately embedded in the corresponding limiting space, thereby achieving precise multi-point positioning of the sealing component installation position and avoiding installation deviations from affecting the sealing effect.

[0010] In one embodiment, the mounting housing includes a housing body and mounting columns. Multiple mounting columns are disposed on the housing body and distributed circumferentially. The circuit board assembly is disposed on the mounting columns and opposite to the housing body. The cover assembly is disposed on the housing body and cooperates to form the mounting space. The housing body provides the programming space. By using the housing body as a basic support frame, on the one hand, the programming space provides a crucial channel for the programming operation of the circuit board assembly, ensuring precise alignment with the programming space when the sealing assembly is opened, meeting the coffee machine's parameter update requirements; on the other hand, the mounting space formed by the cover assembly completely encloses the circuit board assembly, creating a stable working environment for it. Multiple mounting columns distributed circumferentially along the main body of the housing are fixed at one end to the main body of the housing and support the circuit board assembly at the other end. The circumferentially evenly distributed structure provides balanced support for the circuit board assembly, preventing it from shifting or being damaged due to uneven stress caused by the vibration of the coffee machine. It also maintains a relative gap between the circuit board assembly and the main body of the housing, reducing the direct impact of vibration transmitted from the main body of the housing on the circuit board assembly. At the same time, it facilitates air circulation, assists in heat dissipation of the circuit board assembly, and prevents the circuit board assembly from malfunctioning due to heat accumulation caused by long-term operation of the coffee machine.

[0011] In one embodiment, the cover assembly includes a cover main board and mounting clips. The cover main board is disposed on the mounting housing, and there are multiple mounting clips distributed circumferentially along the cover main board. The mounting housing has multiple locking spaces distributed circumferentially along the mounting housing, and the mounting clips abut against the mounting housing and are placed in corresponding locking spaces. By covering the mounting housing with the cover main board and forming mounting spaces, the impact of environmental factors on the stability of the circuit board assembly is reduced. Multiple mounting clips distributed circumferentially along the main cover form a uniform circumferential fixing structure by abutting against the mounting housing and corresponding to multiple circumferential locking spaces. This ensures a tight fit between the main cover and the mounting housing, preventing the main cover from loosening due to vibrations during coffee machine operation and avoiding the formation of protective gaps. Furthermore, the snap-fit ​​connection design allows for the installation and removal of the main cover without the need for additional tools. When it is necessary to inspect the circuit board components, the main cover can be quickly opened, greatly improving operational convenience. In addition, the circumferentially distributed mounting clips ensure even force distribution on the main cover, preventing structural deformation caused by excessive local stress and extending the service life of the cover components.

[0012] In one embodiment, the circuit board assembly includes a circuit board body and a programming component. The circuit board body is disposed on the mounting housing, and the programming component is disposed on the circuit board body and positioned opposite to the portion of the sealing assembly located in the programming space. By fixing the circuit board body to the mounting housing, a stable mounting platform is provided for the programming component, ensuring reliable connection between the programming component and other circuit components and reducing the impact of coffee machine vibration on the programming component. The relative positioning of the programming component and the portion of the sealing assembly located in the programming space allows for direct connection of the programming component simply by opening the sealing assembly when updating the coffee machine program, such as optimizing the extraction algorithm or adding coffee category parameters. This eliminates the need to disassemble the entire circuit board or electrical box, significantly simplifying the programming process, reducing maintenance difficulty, and ensuring rapid device recovery in various application scenarios. Simultaneously, when the sealing assembly is closed, it provides targeted protection for the programming component, preventing corrosion from coffee powder and moisture, ensuring long-term stable operation of the programming component.

[0013] A second aspect of this application discloses an electrical box assembly fixing structure, the electrical box fixing structure comprising: the aforementioned electrical box assembly; a first mounting component disposed on a first side of the electrical box assembly; a second mounting component disposed on a second side of the electrical box assembly, the first side of the electrical box assembly and the second side of the electrical box assembly being disposed opposite to each other; and an assembly housing, the first mounting component and the second mounting component abutting against the assembly housing, the electrical box assembly being mounted on the assembly housing via the first mounting component and the second mounting component.

[0014] The second aspect disclosed above provides a fixing structure for the electrical box assembly. By respectively placing the first and second fittings on the opposite first and second sides of the electrical box assembly, a symmetrical bidirectional support structure is formed. This structure can balance and distribute the weight of the electrical box assembly itself and the vibration and impact forces generated during the operation of the coffee machine, preventing the electrical box assembly from tilting or shifting due to unilateral force or vibration. Simultaneously, both the first and second fittings abut against the assembly housing, securing the electrical box assembly to the housing through the abutment force, eliminating the need for complex bolt connections and simplifying the installation process.

[0015] In one embodiment, the first assembly includes a first assembly body and a protrusion. The first assembly body is disposed on the mounting housing, and the protrusion is disposed on the first assembly body. The mounting housing has a first assembly space and a second assembly space. The protrusion abuts against the mounting housing and is located in the first assembly space, and the second assembly abuts against the mounting housing and is located in the second assembly space. By fixing the first assembly body to the mounting housing, a stable mounting carrier is provided for the protrusion, ensuring accurate positioning of the protrusion and the mounting housing and preventing displacement of the protrusion due to vibration of the coffee machine. The protrusion, disposed on the first assembly body, not only abuts against the mounting housing to form a clamping force but also embeds into the first assembly space. Through the dual fixing method of clamping and space limiting, the electrical box assembly is prevented from loosening in the lateral or longitudinal direction, especially resisting the high-frequency vibration generated during coffee machine operation, preventing the electrical box assembly from dislodging from the preset installation position due to vibration. At the same time, the corresponding cooperation between the second assembly component and the second assembly space forms a symmetrical structure with the cooperation between the first assembly component and the first assembly space, achieving precise positioning and fixation from the opposite sides of the electrical box assembly, so that the electrical box assembly is subjected to balanced forces as a whole.

[0016] In one embodiment, the assembly housing includes a main housing and a bottom housing. The bottom housing is disposed on the main housing. The first assembly component abuts against the main housing, and the second assembly component abuts against the bottom housing. The main housing has a first assembly space, and the bottom housing has a second assembly space. By using the main housing as the core frame of the assembly housing, it supports the installation of the bottom housing, forming a complete assembly space. Furthermore, by providing the first assembly space, it precisely matches the protrusion of the first assembly component, and the abutment between the main housing and the first assembly component achieves precise positioning of one side of the electrical box assembly. The abutting force also enhances the connection stability between the first assembly component and the main housing. The bottom housing is fixed to the main housing, and its second assembly space corresponds and matches the second assembly component. Simultaneously, the bottom housing abuts against the second assembly component, forming a bidirectional fixing structure with the main housing and the first assembly component. This provides support and limitation from opposite sides of the electrical box assembly, preventing tilting or displacement due to uneven force on one side of the fixing, ensuring the overall stable installation of the electrical box assembly.

[0017] In one embodiment, the mounting housing, the first fitting, and the second fitting are integrally molded. By adopting an integral molding design for the mounting housing, the first fitting, and the second fitting, the overall structural strength is significantly improved, enabling more stable resistance to vibrations and impacts during coffee machine operation. This prevents loosening at the connection between the first and second fittings and the mounting housing, ensuring long-term stable installation of the electrical box assembly.

[0018] A third aspect of this application discloses a coffee machine, which includes: the aforementioned electrical box assembly fixing structure; and a coffee machine body disposed on the assembly housing.

[0019] The third aspect disclosed above discloses a coffee machine in which the assembly method of the electrical box component fixing structure simplifies the installation process of the electrical box component. No additional electrical box installation structure needs to be designed; precise positioning of the electrical box can be achieved by relying on limiting structures such as clips. Simultaneously, the programming space on the mounting housing cooperates with the detachable sealing component. When it is necessary to update coffee extraction parameters or optimize the heating program, there is no need to excessively disassemble the coffee machine. Simply opening the sealing component allows the programming space to connect to the programming component of the circuit board component for program input. This operation is convenient and does not affect the normal installation state of the coffee machine body, significantly reducing maintenance difficulty. Attached Figure Description

[0042] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0044] The following describes some embodiments of the present invention, including the electrical box assembly, the electrical box assembly fixing structure, and the coffee machine, with reference to the accompanying drawings.

[0045] Example 1

[0046] like Figures 1 to 9 As shown, this embodiment discloses an electrical box assembly, including: a mounting housing 1, the mounting housing 1 having a programming space 101; a cover assembly 2, the cover assembly 2 being disposed on the mounting housing 1 and cooperating to form the mounting space 102; a circuit board assembly 3, the circuit board assembly 3 being disposed on the mounting housing 1 and located in the mounting space 102; and a sealing assembly 4, the sealing assembly 4 being detachably disposed on the mounting housing 1, a portion of the sealing assembly 4 being located at the programming space 101, and a portion of the circuit board assembly 3 being disposed opposite to the portion of the sealing assembly 4 located at the programming space 101, the sealing assembly 4 being able to open or close the programming space 101.

[0047] This application discloses an electrical box assembly. The programming space 101 provided in the mounting housing 1 cooperates with the detachable sealing component 4. During daily use of the coffee machine, when it is necessary to program the circuit board assembly 3 to update coffee brewing parameters (such as extraction temperature and time adjustment programs), the portion of the circuit board assembly 3 located in the programming space 101 can be directly exposed by opening the sealing component 4, without disassembling the entire electrical box or even the coffee machine body. This greatly simplifies the programming process, avoids the impact of large-scale disassembly on the sealing of the internal pipelines of the coffee machine, and saves maintenance time and labor costs. After programming, the programming space 101 can be tightly closed by the sealing component 4, effectively preventing coffee powder, steam condensate, and external dust generated during the operation of the coffee machine from entering the programming space, preventing these impurities from adhering to critical parts of the circuit board assembly 3 and causing short circuits, poor contact, and other malfunctions. At the same time, the mounting space 102 formed by the cover component 2 and the mounting housing 1 completely encloses the circuit board assembly 3, reducing interference from external environmental factors and lowering the probability of malfunctions.

[0048] like Figure 2 , Figure 4 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines: the sealing assembly 4 includes a sealing base plate 41, a sealing body 42, and a limiting member 43. The sealing base plate 41 is disposed on the mounting housing 1, the sealing body 42 is disposed on the sealing base plate 41 and abuts against the mounting housing 1, the sealing body 42 passes through the burning space 101 and extends into the mounting space 102, the limiting member 43 is disposed on the sealing base plate 41 and abuts against the mounting housing 1, the mounting housing 1 is provided with a limiting space 103, and the limiting member 43 passes through the limiting space 103 and extends into the mounting space 102. By fixing the sealing base plate 41 to the mounting housing 1, a stable mounting reference is provided for the sealing body 42 and the limiting member 43, preventing the sealing components from shifting due to vibration during coffee machine operation, and ensuring the reliability of the overall sealing structure; at the same time, its close fit with the mounting housing 1 can initially prevent coffee powder and moisture from seeping in from the installation gaps, laying the foundation for subsequent sealing protection. The sealing body 42 is not only mounted on the sealing base plate 41, but also abuts against the mounting housing 1 and extends through the burning space 101 to the mounting space 102. This through-type design forms a tight seal at the burning space 101, effectively preventing coffee powder and steam condensation generated during the operation of the coffee machine from entering the burning space 101 and the mounting space 102, thus avoiding corrosion of the circuit board assembly 3. The limiting member 43 passes through the limiting space 103 of the mounting housing 1 and extends to the mounting space 102. By abutting against the mounting housing 1, it further strengthens the connection between the sealing assembly 4 and the mounting housing 1, preventing the sealing assembly 4 from loosening and causing seal failure.

[0049] like Figure 2 , Figure 4 , Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further defines: the sealing body 42 includes a sealing column 421 and a sealing block 422. The sealing column 421 is disposed on the sealing base plate 41 and passes through the burning space 101. The sealing block 422 is disposed on the sealing column 421 and abuts against the mounting housing 1. The sealing block 422 is located in the mounting space 102 and is partially opposite to the circuit board assembly 3. By fixing one end of the sealing column 421 to the sealing base plate 41 and the other end passing through the burning space 101, a longitudinal sealing barrier can be formed in the burning space 101 to prevent coffee powder and steam condensate generated during the operation of the coffee machine from seeping into the mounting space 102 along the longitudinal channel of the burning space 101, thus preventing the critical parts of the circuit board assembly 3 from being corroded; it can also serve as the mounting carrier for the sealing block 422, providing it with stable support. The sealing block 422, located within the installation space 102, abuts tightly against the mounting housing 1. It forms a secondary seal through lateral compression, filling any tiny gaps between the sealing column and the mounting housing, thus enhancing the overall sealing effect and preventing minute impurities from entering through these gaps. Furthermore, the sealing block 422, through the force generated by lateral compression, firmly holds the sealing body 42 within the burning space 101, preventing displacement or loosening of the sealing body 42 due to vibrations during coffee machine operation. This structurally ensures the continuity and reliability of the seal.

[0050] like Figure 4 , Figure 8 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the limiting member 43 includes a limiting post 431 and a limiting block 432. The limiting post 431 is disposed on the sealing base plate 41 and passes through the limiting space 103. The limiting block 432 is disposed on the limiting post 431 and abuts against the mounting housing 1. The limiting block 432 is located in the mounting space 102. By fixing one end of the limiting post 431 to the sealing base plate 41 and the other end passing through the limiting space 103 of the mounting housing 1, it can provide additional support for the connection between the sealing component 4 and the mounting housing 1 through its own longitudinal structure, avoiding the problem of uneven force that may occur when the sealing component 4 is fixed only by the sealing body 42. It can also accurately position the installation position of the sealing component 4 by means of the adaptation and cooperation with the limiting space 103, preventing the sealing component 4 from shifting during installation or vibration during coffee machine operation, and ensuring the corresponding sealing performance between the sealing body 42 and the burning space 101. The limiting block 432 located in the installation space 102 is tightly abutted against the installation housing 1. The lateral clamping force further strengthens the connection between the limiting column 431 and the installation housing 1, forming a double fixing structure of longitudinal support and lateral clamping, which effectively resists the vibration and impact when the coffee machine is working and prevents the limiting part 43 from loosening and causing the sealing assembly 4 to shift as a whole.

[0051] like Figure 4 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: there are multiple limiting members 43, which are disposed on the sealing base plate 41 and located on both sides of the sealing base plate 41; the sealing body 42 is located between the multiple limiting members 43; there are multiple limiting spaces 103, with the multiple limiting members 43 corresponding to each other in the multiple limiting spaces 103. By fixing the multiple limiting members 43 to both sides of the sealing base plate 41 respectively, symmetrical support can be formed from both ends of the sealing assembly 4, avoiding the unbalanced force of the sealing assembly 4 when only one side is set. Especially when the coffee machine generates continuous vibration during operation, the limiting members on both sides can jointly disperse the vibration impact force, preventing the sealing assembly 4 from tilting or shifting due to excessive force on one side, ensuring that the sealing body 42 always accurately corresponds to the burning space 101 and maintains a reliable seal; at the same time, the limiting members 43 distributed on both sides and the sealing body 42 in the middle form a cooperative structure of limiting on both sides plus sealing in the middle, making the overall force of the sealing assembly 4 more uniform, improving the stability of the connection with the mounting housing 1, and reducing the risk of structural deformation after long-term use. In addition, multiple limiting components 43 are inserted one-to-one with multiple limiting spaces 103, which ensures that each limiting component 43 can be accurately embedded in the corresponding limiting space 103, thereby achieving multi-point accurate positioning of the sealing component 4 and avoiding installation deviation from affecting the sealing effect.

[0052] like Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines: the mounting housing 1 includes a housing body 11 and mounting posts 12, the number of mounting posts 12 is multiple, the multiple mounting posts 12 are disposed on the housing body 11 and distributed circumferentially along the housing body 11, the circuit board assembly 3 is disposed on the multiple mounting posts 12 and is disposed opposite to the housing body 11, the cover assembly 2 is disposed on the housing body 11 and cooperates to form a mounting space 102, and the housing body 11 is provided with a programming space 101. By using the housing body 11 as a basic support frame, on the one hand, by setting the programming space 101, a key channel is reserved for the programming operation of the circuit board assembly 3, ensuring that the subsequent opening of the sealing assembly 4 can accurately connect to the programming space 101, meeting the coffee machine parameter update requirements; on the other hand, by cooperating with the cover assembly 2 to form the mounting space 102, the circuit board assembly 3 is completely enclosed within, creating a stable working environment for the circuit board assembly 3. Multiple mounting columns 12 are distributed circumferentially along the main body 11 of the housing. One end is fixed to the main body 11 of the housing, and the other end supports the circuit board assembly 3. The circumferentially evenly distributed structure provides balanced support for the circuit board assembly 3, avoiding the displacement or damage of the circuit board assembly 3 due to uneven force caused by the vibration of the coffee machine. It also maintains a relative gap between the circuit board assembly 3 and the main body 11, reducing the direct impact of the vibration transmitted by the main body 11 on the circuit board assembly 3. At the same time, it facilitates air circulation, assists in heat dissipation of the circuit board assembly 3, and prevents the circuit board assembly 3 from malfunctioning due to the heat accumulation generated by the long-term operation of the coffee machine.

[0053] like Figure 3 , Figure 4 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further defines: the cover assembly 2 includes a cover main board 21 and mounting clips 22. The cover main board 21 is disposed on the mounting housing 1. Multiple mounting clips 22 are disposed on the cover main board 21 and distributed circumferentially along the cover main board 21. The mounting housing 1 has multiple locking spaces 104, distributed circumferentially along the mounting housing 1. The multiple mounting clips 22 abut against the mounting housing 1 and are placed one-to-one in the multiple locking spaces 104. By covering the mounting housing 1 with the cover main board 21 and forming the mounting space 102, the impact of environmental factors on the stability of the circuit board assembly 3 is reduced. Multiple mounting clips 22 distributed circumferentially along the cover main board 21 form a uniform circumferential fixing structure by abutting against the mounting housing 1 and corresponding with multiple circumferential locking spaces 104. This ensures that the cover main board 21 fits tightly against the mounting housing 1, preventing the cover main board 21 from loosening due to vibrations during coffee machine operation and preventing the formation of protective gaps. On the other hand, the clip-on connection design allows for the installation and removal of the cover main board 21 without the need for additional tools. When it is necessary to inspect the circuit board assembly 3, the cover main board 21 can be quickly opened, greatly improving operational convenience. Furthermore, the circumferentially distributed mounting clips 22 ensure that the cover main board 21 is subjected to balanced force, avoiding structural deformation caused by excessive local force and extending the service life of the cover assembly 2.

[0054] like Figure 3 , Figure 4 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further defines: the circuit board assembly 3 includes a circuit board body 31 and a programming component 32. The circuit board body 31 is disposed on the mounting housing 1, and the programming component 32 is disposed on the circuit board body 31 and is positioned opposite to the portion of the sealing component 4 located in the programming space 101. By fixing the circuit board body 31 to the mounting housing 1, a stable mounting platform is provided for the programming component 32, ensuring reliable connection between the programming component 32 and other circuit components, and reducing the impact of coffee machine vibration on the programming component 32. The programming component 32 and the portion of the sealing component 4 located in the programming space 101 are positioned opposite each other. When it is necessary to update the coffee machine program, such as optimizing the extraction algorithm or adding coffee category parameters, it is only necessary to open the sealing component 4 to directly connect the programming component 32 without disassembling the entire circuit board or electrical box, greatly simplifying the programming operation process, reducing maintenance difficulty, and ensuring that the equipment can be quickly restored to use in various application scenarios. At the same time, when the sealing component 4 is closed, it can provide targeted protection for the programming component 32, blocking coffee powder and moisture corrosion, and ensuring long-term stable operation of the programming component 32.

[0055] Example 2

[0056] like Figures 1 to 14As shown, this embodiment discloses an electrical box assembly fixing structure, including: the aforementioned electrical box assembly; a first mounting part 5, which is disposed on a first side of the electrical box assembly; a second mounting part 6, which is disposed on a second side of the electrical box assembly, with the first side of the electrical box assembly and the second side of the electrical box assembly being disposed opposite to each other; and an assembly housing 7, with the first mounting part 5 and the second mounting part 6 abutting against the assembly housing 7, and the electrical box assembly being mounted on the assembly housing 7 via the first mounting part 5 and the second mounting part 6.

[0057] The second aspect of this application discloses a fixing structure for an electrical box assembly. By respectively placing the first mounting part 5 and the second mounting part 6 on the opposite first and second sides of the electrical box assembly, a symmetrical bidirectional support structure is formed. This structure can balance and distribute the weight of the electrical box assembly itself and the vibration and impact force generated during the operation of the coffee machine, preventing the electrical box assembly from tilting or shifting due to unilateral force or vibration. Simultaneously, both the first mounting part 5 and the second mounting part 6 abut against the assembly housing 7, and the abutment force securely installs the electrical box assembly onto the assembly housing 7, eliminating the need for complex bolt connections and simplifying the installation process.

[0058] like Figures 10 to 14 As shown, in addition to the features of the above embodiments, this embodiment further defines: the first assembly 5 includes a first assembly body 51 and a protrusion 52. The first assembly body 51 is disposed on the mounting housing 1, and the protrusion 52 is disposed on the first assembly body 51. The mounting housing 7 has a first assembly space 701 and a second assembly space 702. The protrusion 52 abuts against the mounting housing 7 and is located at the first assembly space 701. The second assembly 6 abuts against the mounting housing 7 and is located at the second assembly space 702. By fixing the first assembly body 51 to the mounting housing 1, a stable mounting carrier is provided for the protrusion 52, ensuring accurate mating position between the protrusion 52 and the mounting housing 7, and preventing the protrusion 52 from shifting due to vibration of the coffee machine. The protrusion 52 is provided on the first assembly body 51, which not only abuts against the assembly housing 7 to form a clamping force, but also embeds into the first assembly space 701. Through the dual fixing method of clamping and spatial limiting, it prevents the electrical box assembly from loosening in the lateral or longitudinal direction, and can especially resist the high-frequency vibration generated when the coffee machine is working, preventing the electrical box assembly from being dislodged from the preset installation position due to vibration. At the same time, the corresponding cooperation between the second assembly 6 and the second assembly space 702, together with the cooperation between the first assembly 5 and the first assembly space 701, forms a symmetrical structure, achieving precise positioning and fixing from opposite sides of the electrical box assembly, so that the overall force on the electrical box assembly is balanced.

[0059] like Figures 10 to 14As shown, in addition to the features of the above embodiments, this embodiment further defines: the assembly housing 7 includes a main housing 71 and a bottom housing 72, the bottom housing 72 is disposed on the main housing 71, the first assembly part 5 abuts against the main housing 71, the second assembly part 6 abuts against the bottom housing 72, the main housing 71 is provided with a first assembly space 701, and the bottom housing 72 is provided with a second assembly space 702. By using the main housing 71 as the core frame of the assembly housing 7, on the one hand, it supports the installation of the bottom housing 72, forming a complete assembly space; on the other hand, by setting the first assembly space 701, it precisely matches the protrusion 52 of the first assembly part 5, and the main housing 71 abuts against the first assembly part 5, achieving precise positioning of one side of the electrical box assembly, and also enhancing the connection stability between the first assembly part 5 and the main housing 71 through the abutment force. The bottom shell 72 is fixed on the main shell 71. The second assembly space 702 provided therein corresponds to and is adapted to the second assembly 6. At the same time, the bottom shell 72 abuts against the second assembly 6, and together with the main shell 71 and the first assembly 5, they form a two-way fixing structure from top to bottom. This provides support and limit from the opposite sides of the electrical box assembly, preventing the electrical box assembly from tilting or shifting due to uneven force on one side of the fixing, and ensuring that the electrical box assembly is installed stably as a whole.

[0060] like Figure 1 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the mounting housing 1, the first assembly 5, and the second assembly 6 are integrally formed. By adopting an integrally formed design for the mounting housing 1, the first assembly 5, and the second assembly 6, the overall structural strength is greatly improved, which can more stably resist the vibration and impact during the operation of the coffee machine, prevent the connection between the first assembly 5 and the second assembly 6 and the mounting housing 1 from loosening, and ensure the long-term stable installation of the electrical box assembly.

[0061] Example 3

[0062] like Figures 1 to 14 As shown, this embodiment discloses a coffee machine, including: the above-mentioned electrical box assembly fixing structure; and a coffee machine body, which is mounted on the assembly housing 7.

[0063] The third aspect of this application discloses a coffee machine in which the assembly method of the electrical box assembly fixing structure simplifies the installation process of the electrical box assembly. No additional electrical box installation structure needs to be designed; precise positioning of the electrical box can be achieved by relying on limiting structures such as clips. Simultaneously, the programming space 101 on the mounting housing 1 cooperates with the detachable sealing component 4. When it is necessary to update coffee extraction parameters or optimize the heating program, there is no need to excessively disassemble the coffee machine. Simply opening the sealing component 4 allows program input through the programming space 101 to connect with the programming component 32 of the circuit board assembly 3. This operation is convenient and does not affect the normal installation state of the coffee machine body, significantly reducing maintenance difficulty.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
