Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to a lid detection device and a coffee machine. Background Technology

[0002] In current technological scenarios, although the coffee machine lid is designed to be detachable to accommodate daily maintenance needs, the lack of a corresponding lid detection structure presents a significant safety vulnerability: if the lid is not fully closed during operation, or if it becomes loose or shifted due to vibration or accidental contact after being closed, the coffee machine will still maintain its normal operating capability. In this situation, the high-temperature steam generated by the machine, no longer sealed by the lid, will freely escape from the gap between the lid and the casing. Direct contact of this hot steam with the human body can easily cause burns. Utility Model Content

[0003] Therefore, it is necessary to provide a lid detection device and a coffee machine to address the problem of the lack of a detection device for the top lid of the coffee machine.

[0004] A cover detection device includes: a top cover assembly having a receiving space; a housing assembly including a main housing and an upper housing assembly, the upper housing assembly being disposed on the main housing, and the top cover assembly being detachable from the main housing and the upper housing assembly; a magnetic suction element disposed on the top cover assembly and located in the receiving space; and a sensing element disposed on the upper housing assembly, the sensing element being disposed opposite to the magnetic suction element across the top cover assembly and / or the upper housing assembly.

[0005] The above-disclosed device is a lid detection device for coffee machines. Through the precise cooperation of a magnetic component and a sensor, it can detect in real time whether the lid assembly is reliably closed on the main housing and upper housing assembly. When the lid assembly is not closed or is not properly closed, the sensor cannot detect the signal from the magnetic component, directly triggering the coffee machine's stop or start-prevention mechanism, fundamentally preventing the equipment from operating without a lid. This design effectively eliminates the risk of uncontrolled steam leakage, preventing burns to operators from high-temperature steam, and also prevents coffee bean powder, hot water, etc., from splashing during equipment operation, thus completely eliminating various safety hazards associated with lidless operation. Moreover, since the lid assembly is detachable from the housing assembly, when the coffee machine requires internal maintenance, users or repair personnel can easily remove the lid assembly without the need for specialized tools or complex procedures, directly accessing the core components such as the internal piping, heating elements, and grinding structure, significantly reducing maintenance difficulty and shortening maintenance time.

[0006] In one embodiment, the top cover assembly includes a top cover body and a mating cover. The mating cover is disposed on the top cover body and cooperates to form the receiving space. The magnetic attractor is disposed on the mating cover. The top cover body is detachable from the main housing and the upper housing assembly. Through the mating arrangement of the mating cover and the top cover body, the receiving space can be precisely enclosed, providing a stable mounting carrier for the magnetic attractor. This prevents the magnetic attractor from being directly exposed to the outside and damaged by external forces or weakened by coffee powder or moisture, ensuring the accuracy of the relative position between the magnetic attractor and the sensing element and the stable transmission of the magnetic signal, thereby ensuring the reliability of the top cover closing detection.

[0007] In one embodiment, the top cover body includes a top cover panel, a first structural reinforcement, a second structural reinforcement, and an assembly. The first structural reinforcement is disposed on the top cover panel and surrounds the top cover panel. The first structural reinforcement protrudes in a direction away from the top cover panel and abuts against the main housing and the upper housing assembly. The second structural reinforcement is disposed on the top cover panel and located on a side away from the first structural reinforcement. The second structural reinforcement is located at both ends of the top cover panel. The assembly is disposed on the top cover panel and sandwiched between the second structural reinforcements. A mating cover is disposed on the second structural reinforcement and the assembly. The top cover panel, the second structural reinforcement, the assembly, and the mating cover cooperate to form the receiving space. By using the top cover panel as the basic load-bearing component, it provides an installation reference for other components. The first structural reinforcement surrounds the top cover panel and protrudes outward, which not only enhances the overall structural strength of the top cover panel and prevents it from deforming under stress, but also ensures precise abutment with the main shell and upper shell components when the top cover assembly is closed, forming a stable assembly relationship. This ensures the sealing and positional accuracy of the top cover after it is closed, and avoids affecting the detection effect due to looseness. The second structural reinforcement is located on the side of the top cover panel away from the first structural reinforcement and is distributed at both ends. This further enhances the structural stability of the top cover panel and provides reliable installation support points for the mating cover. The assembly is clamped between the two second structural reinforcements, and together with the second structural reinforcements, it builds a stable installation frame for the mating cover, ensuring that the mating cover can be accurately fixed. This, in turn, forms a uniformly sized accommodating space with the top cover body, providing a stable installation environment for the magnetic components, ensuring the relative positional accuracy of the magnetic components and the sensing components, and helping to reliably realize the detection function.

[0008] In one embodiment, both the second structural reinforcement and the assembly are provided with multiple locking spaces. Some of these locking spaces are located on the second structural reinforcement, while the remaining spaces are distributed on both sides of the assembly. The mating cover is located in one of these multiple locking spaces. The multiple locking spaces on the second structural reinforcement and the assembly provide precise and stable positioning for the installation of the mating cover. The distributed and symmetrical arrangement of the locking spaces—some on the second structural reinforcement and others on both sides of the assembly—allows for multi-point locking and limiting of the mating cover from different positions. This prevents the mating cover from shifting, loosening, or shaking after installation, ensuring a precise assembly relationship between the mating cover and the top cover body. This, in turn, guarantees the stability of the enclosed space and prevents deformation of the space due to cover displacement, which could affect the installation stability of the magnetic components. Meanwhile, the multi-point locking structure can enhance the connection strength between the mating cover and the main body of the top cover, reduce the impact of vibration on the mating cover during the operation of the coffee machine, prevent the magnetic components from deviating from their relative positions with the sensing components due to the displacement of the mating cover, ensure the accuracy of magnetic signal transmission, and further ensure the reliable realization of the top cover closing detection function. In addition, the precise locking space also provides a positioning benchmark for the disassembly and assembly of the mating cover, simplifying the operation process when maintaining or replacing the mating cover and improving the overall device's maintenance convenience.

[0009] In one embodiment, the top cover body further includes multiple flow guides, which are spaced apart along the width of the top cover panel. Adjacent flow guides cooperate to form multiple flow guide spaces, and the flow guides extend along the length of the top cover panel. By arranging multiple flow guides spaced apart along the width of the top cover panel and extending along its length, the multiple flow guide spaces formed by adjacent flow guides can accurately collect water dripping or remaining on the outside of the cup. When the cup is placed on the top cover panel, the water flowing down its outside is guided by the flow guides to the corresponding flow guide spaces. These flow guide spaces can temporarily accumulate the water, preventing it from spreading randomly on the surface of the top cover panel and preventing water from seeping into the connection gaps between the top cover body and the main shell / upper shell assembly. In addition, water that temporarily accumulates in the drainage space is more likely to evaporate naturally due to its relatively large contact area with air, which can quickly eliminate water accumulation on the top cover panel and keep the top cover surface dry and clean. The drainage components that are spaced apart and extend along the length direction can further enhance the structural strength of the top cover panel, reduce the deformation of the top cover panel caused by temperature changes or external force, and work together with other reinforcing components to improve the overall stability of the top cover body and extend the service life of the top cover assembly.

[0010] In one embodiment, the top cover body further includes an exhaust component, which is disposed on the top cover panel and protrudes in a direction away from the top cover panel. The exhaust component has multiple exhaust spaces, which are distributed along the length of the exhaust component. By utilizing the structural design of the exhaust component protruding away from the top cover panel, a height difference is formed between it and the top cover panel, preventing the discharged steam from directly contacting the panel or the components below. The multiple exhaust spaces distributed along the length of the exhaust component can achieve the dispersion and efficient discharge of steam. When steam is generated inside the coffee machine due to heating, the steam can be released in an orderly manner through these exhaust spaces, preventing excessive internal steam pressure from causing the top cover seal to fail or causing component damage due to a sudden increase in pressure. At the same time, it prevents steam from accumulating inside and overflowing from the connection gap between the top cover and the housing, reducing the safety hazards of high-temperature steam to the operator. In addition, the dispersed exhaust spaces can also reduce the steam flow rate of a single exhaust port, preventing steam from splashing due to excessive flow rate carrying coffee powder or water droplets, keeping the area around the top cover clean.

[0011] In one embodiment, the mating cover includes a mating cover body and a mounting component. The mounting component is disposed on the mating cover body, and the magnetic suction component is disposed on the mounting component. The mating cover body is disposed on the top cover body and together forms the receiving space. By precisely mating the mating cover body and the top cover body to form the receiving space, an independent and enclosed installation environment is provided for the magnetic suction component, preventing it from being corroded by external moisture or coffee powder, and ensuring its magnetic stability. The mounting component, disposed on the mating cover body, provides a stable mounting carrier for the magnetic suction component. Through positioning and fixing, the accurate position of the magnetic suction component is ensured, preventing displacement of the magnetic suction component due to vibration during coffee machine operation. This ensures that the magnetic suction component and the sensing component always remain in a relatively aligned state, ensuring stable transmission of the top cover closing detection signal.

[0012] In one embodiment, the mating cover body includes a main mating cover and mating hooks. Multiple mating hooks are arranged circumferentially along the main mating cover. The top cover body has multiple locking spaces. Multiple mating hooks are disposed on the top cover body and correspond one-to-one with each locking space. The mounting component is disposed on the main mating cover. The main mating cover, serving as the core framework of the mating cover body, not only provides a stable mounting base for the mounting component, ensuring the magnetic component's position is fixed, but also precisely aligns with the top cover body, forming a sealed enclosure that continuously isolates the magnetic component from external moisture and coffee powder, preventing magnetic attenuation. The multiple mating hooks arranged circumferentially along the main mating cover correspond one-to-one with the multiple locking spaces on the top cover body. Through hook-and-lock positioning, the mating cover body and the top cover body are quickly assembled and securely connected, preventing displacement of the mating cover body due to vibration during coffee machine operation. This ensures that the magnetic component and the sensing component remain in relative alignment, guaranteeing stable transmission of the detection signal.

[0013] In one embodiment, the upper shell assembly includes an upper shell body, a first limiting member, and a second limiting member. The upper shell body is disposed on the main shell. Multiple first limiting members are disposed on the upper shell body and located on the side away from the top cover assembly. Multiple second limiting members are also disposed on the upper shell body and located on the side away from the top cover assembly. The multiple first limiting members, the multiple second limiting members, and the upper shell body cooperate to form the limiting space. The sensing element is disposed on the multiple first limiting members and the multiple second limiting members and located within the limiting space. The upper shell body serves as the basic load-bearing structure, securely mounted on the main shell. This not only provides a precise installation reference for the first and second limiting members, ensuring their regular positions, but also allows for a good assembly fit with the top cover assembly, laying the foundation for the overall structural stability of the cover detection device. The multiple first and second limiting members are all located on the side of the upper shell body away from the top cover assembly, and the limiting space formed by their cooperation enables omnidirectional positioning and fixation of the sensing element. This design prevents sensor displacement through circumferential limiting and avoids sensor detachment due to external impacts or vibrations using structural enclosures. This ensures the sensor remains in its preset position corresponding to the magnetic attraction component, guaranteeing accurate signal transmission between them. This, in turn, improves the sensitivity and reliability of the top cover closing detection, effectively preventing detection failures caused by sensor displacement. Furthermore, this multi-limiting, fixed structural design eliminates the need for complex connectors, simplifying the sensor installation process and facilitating future maintenance and replacement.

[0014] In one embodiment, the second limiting member includes a support member and a hook. The support member is disposed on the upper shell body, and the hook is disposed on the support member and protrudes towards the limiting space. The support member and the hook abut against the sensor. The support member, securely mounted on the upper shell body, provides a solid mounting carrier for the hook, ensuring structural stability. Furthermore, its contact with the sensor creates a horizontal limiting constraint, effectively preventing horizontal displacement of the sensor due to vibrations during coffee machine operation or minor external impacts, ensuring it remains in a preset position on the horizontal plane. The hook, protruding towards the limiting space and abutting against the sensor, primarily provides vertical limiting. Its snap-fit ​​structure supports the sensor, preventing it from sinking or falling off under gravity, thus reliably fixing the sensor vertically. Together, they form a three-dimensional limiting system, ensuring the sensor is always accurately aligned with the magnetic component, guaranteeing stable signal transmission, and significantly reducing the risk of detection failure.

[0015] The second aspect of this application discloses a coffee machine, which includes: the aforementioned lid detection device; and a coffee machine body disposed on the housing assembly.

[0016] The second aspect disclosed above discloses a coffee machine in which the main body of the coffee machine is mounted on a housing assembly. When the top cover assembly is closed on the housing assembly, the magnetic component on the top cover assembly is precisely aligned with the sensor on the upper housing assembly. The coffee machine can only start operating normally after the sensor detects the signal from the magnetic component. If the top cover assembly is not closed or is not properly closed, the magnetic component and the sensor cannot form an effective signal connection, and the sensor will trigger a stop or start-prevention mechanism for the coffee machine. This design eliminates the risk of the coffee machine operating with the top cover open, preventing uncontrolled high-temperature steam from scalding operators and avoiding safety accidents caused by coffee powder or hot water splashing.

[0034] 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.

[0035] 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.

[0036] The following describes some embodiments of the lid detection device and coffee machine of this utility model with reference to the accompanying drawings.

[0037] Example 1

[0038] like Figures 1 to 12 As shown, this embodiment discloses a cover detection device, including: a top cover assembly 1, the top cover assembly 1 having a receiving space 101; a shell assembly 2, the shell assembly 2 including a main shell 21 and an upper shell assembly 22, the upper shell assembly 22 being disposed on the main shell 21, and the top cover assembly 1 being detachable from the main shell 21 and the upper shell assembly 22; a magnetic suction member 3, the magnetic suction member 3 being disposed on the top cover assembly 1 and located in the receiving space 101; and a sensing member 4, the sensing member 4 being disposed on the upper shell assembly 22, the sensing member 4 being disposed opposite to the magnetic suction member 3 across the top cover assembly 1 and / or the upper shell assembly 22.

[0039] This application discloses a lid detection device for coffee machines. Through the precise cooperation of the magnetic suction element 3 and the sensing element 4, it can detect in real time whether the top lid assembly 1 is reliably closed on the main housing 21 and the upper housing assembly 22. When the top lid assembly 1 is not closed or is not properly closed, the sensing element 4 cannot detect the signal from the magnetic suction element 3, which can directly trigger the coffee machine's stop or prevent start-up mechanism, fundamentally preventing the equipment from operating without a lid. This design effectively eliminates the risk of uncontrolled steam leakage, preventing burns to operators from high-temperature steam, and also prevents coffee bean powder, hot water, etc., from splashing during equipment operation, thus completely eliminating various safety hazards associated with lidless operation. Moreover, since the top lid assembly 1 is detachable from the housing assembly 2, when the coffee machine requires internal maintenance, users or repair personnel can easily remove the top lid assembly 1 without the need for professional tools or complex procedures, directly accessing the core components such as the internal pipes, heating elements, and grinding structure of the coffee machine, significantly reducing the difficulty of maintenance and shortening maintenance time.

[0040] like Figure 2 , Figure 3 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines: the top cover assembly 1 includes a top cover body 11 and a mating cover 12. The mating cover 12 is disposed on the top cover body 11 and forms a receiving space 101. The magnetic suction element 3 is disposed on the mating cover 12. The top cover body 11 is detachable from the main housing 21 and the upper housing assembly 22. Through the mating arrangement of the mating cover 12 and the top cover body 11, the receiving space 101 can be precisely enclosed to provide a stable mounting carrier for the magnetic suction element 3. This avoids the magnetic suction element 3 from being directly exposed to the outside and damaged by external forces or weakened by coffee powder or moisture. It ensures the accuracy of the relative position between the magnetic suction element 3 and the sensing element 4 and the stable transmission of the magnetic attraction signal, thereby ensuring the reliability of the top cover closing detection.

[0041] like Figure 4 , Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines: the top cover body 11 includes a top cover panel 111, a first structural reinforcement 112, a second structural reinforcement 113, and an assembly 114. The first structural reinforcement 112 is disposed on the top cover panel 111 and surrounds the top cover panel 111. The first structural reinforcement 112 protrudes in a direction away from the top cover panel 111 and abuts against the main housing 21 and the upper housing assembly 22. The second structural reinforcement 113 is disposed on the top cover panel 111 and located on the side away from the first structural reinforcement 112. The second structural reinforcement 113 is located at both ends of the top cover panel 111. The assembly 114 is disposed on the top cover panel 111 and sandwiched between the second structural reinforcement 113. The mating cover 12 is disposed on the second structural reinforcement 113 and the assembly 114. The top cover panel 111, the second structural reinforcement 113, the assembly 114, and the mating cover 12 cooperate to form an accommodating space 101. By using the top cover panel 111 as the basic load-bearing component, an installation reference is provided for other components; the first structural reinforcement 112 surrounds the top cover panel 111 and protrudes outward, which not only enhances the overall structural strength of the top cover panel 111 and prevents it from deforming under stress, but also precisely abuts against the main housing 21 and the upper housing assembly 22 when the top cover assembly 1 is closed, forming a stable assembly relationship, ensuring the sealing and positional accuracy of the top cover after it is closed, and avoiding the impact of loosening of the cover on the detection effect. The second structural reinforcement 113 is located on the side of the top cover panel 111 away from the first structural reinforcement 112 and is distributed at both ends. It not only further improves the structural stability of the top cover panel 111, but also provides a reliable installation support point for the mating cover 12. The mounting accessory 114 is sandwiched between the two second structural reinforcements 113. Together with the second structural reinforcements 113, it builds a stable installation frame for the mating cover 12, ensuring that the mating cover 12 can be accurately fixed. In turn, it works with the top cover body 11 to form a uniformly sized accommodating space 101, providing a stable installation environment for the magnetic suction component 3, ensuring the relative positional accuracy of the magnetic suction component 3 and the sensing component 4, and helping to reliably realize the detection function.

[0042] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: both the second structural reinforcement 113 and the assembly 114 are provided with locking spaces 102, and there are multiple locking spaces 102. Some locking spaces 102 are located at the second structural reinforcement 113, and the remaining locking spaces 102 are distributed on both sides of the assembly 114, with the cover 12 located at multiple locking spaces 102. The provision of multiple locking spaces 102 on the second structural reinforcement 113 and the assembly 114 provides a precise and stable positioning guarantee for the installation of the cover 12. Part of the locking space 102 is located at the second structural reinforcement 113, and the rest are distributed on both sides of the assembly 114. This dispersed and symmetrical distribution can lock and limit the mating cover 12 at multiple points from different positions, preventing the mating cover 12 from shifting, loosening or shaking after installation. This ensures that the mating cover 12 and the top cover body 11 always maintain a precise assembly relationship, thereby ensuring that the size of the enclosed space 101 is stable and preventing the enclosed space 101 from deforming due to the displacement of the mating cover 12, which would affect the installation stability of the magnetic suction component 3. Meanwhile, the multi-point locking structure can also enhance the connection strength between the mating cover 12 and the top cover body 11, reduce the impact of vibration on the mating cover 12 during the operation of the coffee machine, prevent the magnetic suction part 3 from deviating from the relative position of the sensing part 4 due to the displacement of the mating cover 12, ensure the accuracy of magnetic signal transmission, and further ensure the reliable realization of the top cover closing detection function. In addition, the precise locking space 102 also provides a positioning reference for the disassembly and assembly of the mating cover 12, simplifying the operation process when maintaining or replacing the mating cover 12 and improving the maintenance convenience of the overall device.

[0043] like Figure 4 , Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the top cover body 11 also includes multiple guide members 115, which are spaced apart on the top cover panel 111 along the width direction. Adjacent guide members 115 cooperate to form a guide space 103, and there are multiple guide spaces 103. The guide members 115 extend along the length direction of the top cover panel 111. By arranging multiple guide members 115 at intervals along the width direction of the top cover panel 111 and extending along the length direction, the multiple guide spaces 103 formed by the cooperation of adjacent guide members 115 can accurately catch water dripping or remaining on the outside of the cup. When a cup is placed on the top cover panel 111, the water on its outer side flows down and is guided by the guide member 115 into the corresponding guide space 103. The guide space 103 can temporarily accumulate this water, preventing the water from spreading randomly on the surface of the top cover panel 111 and preventing water from seeping into the connection gap between the top cover body 11 and the main shell 21 and the upper shell assembly 22. In addition, the water that temporarily accumulates in the guide space 103 has a relatively large contact area with the air, making it easier to evaporate naturally and quickly eliminate the water accumulation on the top cover panel 111, keeping the top cover surface dry and clean. The guide members 115, which are spaced apart and extend along the length direction, can further enhance the structural strength of the top cover panel 111, reduce the deformation of the top cover panel 111 caused by temperature changes or external force, and work with other reinforcing members to improve the overall stability of the top cover body 11 and extend the service life of the top cover assembly 1.

[0044] like Figure 4 , Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the top cover body 11 also includes an exhaust member 116, which is disposed on the top cover panel 111 and protrudes in a direction away from the top cover panel 111. The exhaust member 116 is provided with exhaust spaces 104, and there are multiple exhaust spaces 104 distributed along the length direction of the exhaust member 116. By utilizing the structural design of the exhaust member 116 protruding in a direction away from the top cover panel 111, a height difference is formed between it and the top cover panel 111, preventing the discharged steam from directly contacting the panel or the components below; and the multiple exhaust spaces 104 distributed along the length direction of the exhaust member 116 can achieve the dispersion and efficient discharge of steam. When steam is generated inside the coffee machine due to heating, the steam can be released in an orderly manner through these exhaust spaces 104, preventing the top cover seal from failing due to excessive internal steam pressure, or causing component damage due to a sudden increase in pressure. At the same time, it prevents steam from accumulating inside and overflowing from the connection gap between the top cover and the shell, reducing the safety hazards of high-temperature steam to the operator. In addition, the dispersed exhaust spaces 104 can reduce the steam flow rate of a single exhaust port, preventing coffee powder or water droplets from splashing out due to excessive flow rate when steam is discharged, thus keeping the area around the top cover clean.

[0045] like Figure 3 , Figure 8 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further defines: the mating cover 12 includes a mating cover body 121 and a mounting member 122. The mounting member 122 is disposed on the mating cover body 121, and the magnetic suction member 3 is disposed on the mounting member 122. The mating cover body 121 is disposed on the top cover body 11 and forms a receiving space 101. By precisely mating the mating cover body 121 and the top cover body 11 to form the receiving space 101, an independent and closed installation environment is provided for the magnetic suction member 3, preventing the magnetic suction member 3 from being corroded by external moisture and coffee powder, and ensuring its magnetic stability. The mounting member 122, disposed on the mating cover body 121, can provide a stable mounting carrier for the magnetic suction member 3. By positioning and fixing, the position of the magnetic suction member 3 is ensured to be accurate, preventing the magnetic suction member 3 from shifting due to vibration during coffee machine operation. This ensures that the magnetic suction member 3 and the sensing member 4 always maintain a relatively aligned state, ensuring stable transmission of the top cover closing detection signal.

[0046] like Figure 8 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further defines: the mating cover body 121 includes a main mating cover 1211 and mating hook blocks 1212, the number of mating hook blocks 1212 is multiple, the multiple mating hook blocks 1212 are arranged circumferentially along the main mating cover 1211, the top cover body 11 is provided with a locking space 102, the number of locking spaces 102 is multiple, the multiple mating hook blocks 1212 are arranged on the top cover body 11 and correspond one-to-one with the multiple locking spaces 102, and the mounting member 122 is arranged on the main mating cover 1211. The main mating cover 1211 serves as the core framework of the mating cover body 121, providing a stable installation base for the mounting component 122 and ensuring the fixed position of the magnetic component 3. It also precisely aligns with the top cover body 11, forming a sealed receiving space 101 to continuously isolate the magnetic component 3 from external moisture and coffee powder, preventing its magnetic attenuation. Multiple mating hooks 1212 arranged circumferentially along the main mating cover 1211 correspond one-to-one with multiple locking spaces 102 on the top cover body 11. Through hook-and-lock positioning, the mating cover body 121 and the top cover body 11 are quickly assembled and securely connected, preventing the mating cover body 121 from shifting due to vibration during coffee machine operation. This ensures that the magnetic component 3 and the sensing component 4 always maintain a relatively aligned state, guaranteeing stable transmission of detection signals.

[0047] like Figure 2 , Figure 10 , Figure 11 and Figure 12As shown, in addition to the features of the above embodiments, this embodiment further defines: the upper shell assembly 22 includes an upper shell body 221, a first limiting member 222 and a second limiting member 223. The upper shell body 221 is disposed on the main shell 21. There are multiple first limiting members 222, which are disposed on the upper shell body 221 and located on the side away from the top cover assembly 1. There are multiple second limiting members 223, which are disposed on the upper shell body 221 and located on the side away from the top cover assembly 1. The multiple first limiting members 222, the multiple second limiting members 223 and the upper shell body 221 cooperate to form a limiting space 201. The sensing member 4 is disposed on the multiple first limiting members 222 and the multiple second limiting members 223 and located in the limiting space 201. The upper shell 221 serves as the basic load-bearing structure, securely mounted on the main shell 21. This provides a precise installation reference for the first and second limiting components 222 and 223, ensuring their proper positioning. It also allows for a good fit with the top cover assembly 1, laying the foundation for the overall structural stability of the cover detection device. Multiple first and second limiting components 222 and 223 are positioned on the side of the upper shell 221 away from the top cover assembly 1. The limiting space 201 formed by these components provides omnidirectional positioning and fixation for the sensor 4. This circumferential limiting action prevents the sensor 4 from shifting, while the structural enclosure prevents it from falling off due to external collisions or vibrations. This ensures the sensor 4 remains in the preset position corresponding to the magnetic component 3, guaranteeing the accuracy of signal transmission between them. This improves the sensitivity and reliability of the top cover closing detection, effectively preventing detection failures caused by sensor 4 displacement. In addition, this multi-limiting component combined with a fixed structural design eliminates the need for complex connectors, simplifying the installation process of the sensor 4 and facilitating later maintenance and replacement.

[0048] like Figure 10 and Figure 11As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second limiting member 223 includes a support member 2231 and a hook 2232. The support member 2231 is disposed on the upper shell body 221, and the hook 2232 is disposed on the support member 2231 and protrudes towards the limiting space 201. The support member 2231 and the hook 2232 abut against the sensor 4. By being securely disposed on the upper shell body 221 by the support member 2231, on the one hand, a solid mounting carrier is provided for the hook 2232, ensuring the structural stability of the hook 2232. On the other hand, through the abutting contact with the sensor 4, a limiting constraint is formed on the sensor 4 in the horizontal direction, effectively preventing the sensor 4 from being horizontally displaced due to vibration during the operation of the coffee machine or slight external collisions, ensuring that it is always in a preset position on the horizontal plane. The hook 2232 protrudes towards the limiting space 201 and abuts against the sensor 4, primarily serving a vertical limiting function. Its snap-fit ​​structure supports the sensor 4, preventing it from sinking or falling off under gravity, thus reliably fixing the sensor 4 vertically. Together, these two elements form a three-dimensional limiting system, ensuring the sensor 4 is always precisely aligned with the magnetic attractor 3, guaranteeing stable signal transmission and significantly reducing the risk of detection failure.

[0049] Example 2

[0050] like Figures 1 to 12 As shown, this embodiment discloses a coffee machine, including: the aforementioned lid detection device; and a coffee machine body, which is mounted on the housing assembly 2.

[0051] The second aspect of this application discloses a coffee machine in which the main body is mounted on a housing assembly 2. When the top cover assembly 1 is closed on the housing assembly 2, the magnetic 3 on the top cover assembly 1 is precisely aligned with the sensor 4 on the upper shell assembly 22 of the housing assembly 2. After the sensor 4 detects the signal from the magnetic 3, the main body of the coffee machine can start working normally. If the top cover assembly 1 is not closed or is not closed properly, the magnetic 3 and the sensor 4 cannot form an effective signal connection, and the sensor 4 will trigger a stop or start-prevention mechanism for the coffee machine. This design eliminates the risk of the coffee machine operating with the top cover open, preventing high-temperature steam from escaping unrestrained and scalding the operator, and avoiding safety accidents caused by coffee powder or hot water splashing.

[0052] 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.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. 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. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
