Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a ventilation structure for a cleaning machine and a cleaning machine. Background Technology

[0002] As a commonly used cleaning equipment, cleaning machines generate steam within the cleaning chamber during operation. Therefore, a venting structure is required at the opening to allow the steam to escape. In existing technology, some cleaning machines lack a venting structure at the opening, failing to expel excess steam from the chamber; others, while having a venting structure, are easily blown out by steam. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0003] Therefore, it is necessary to provide a ventilation structure for a cleaning machine to address the issues of how to set up a ventilation structure to discharge excess steam in the cleaning chamber and how to prevent the ventilation structure from being blown out by steam.

[0004] A ventilation structure for a cleaning machine includes: a cover assembly; a baffle assembly disposed on the cover assembly, the baffle assembly and the cover assembly cooperating to form a mounting groove, the cover assembly having a first air outlet communicating with the mounting groove, the first air outlet being located on the side of the baffle assembly; and a ventilation component detachably mounted on the cover assembly or the baffle assembly and at least partially located within the mounting groove, the ventilation component having a ventilation hole communicating with the first air outlet.

[0005] This application discloses a ventilation structure for a cleaning machine. A complete ventilation system is constructed through the cooperation of a cover assembly, a baffle assembly, and a ventilation component. The detachable ventilation component facilitates quick replacement and cleaning during equipment maintenance or when the ventilation holes are clogged, reducing equipment maintenance costs and downtime. The first air outlet communicates with the ventilation hole, optimizing the gas discharge path, reducing flow resistance, preventing excessive internal air pressure and water vapor condensation, and protecting internal components. The mounting groove formed by the cover assembly and the baffle assembly accommodates the ventilation component, preventing it from shifting due to airflow impact; simultaneously, the reasonable layout blocks external dust and impurities from entering, ensuring stable ventilation function.

[0006] In one embodiment, the cover assembly includes a cover and a connecting portion. The connecting portion is disposed on the cover, and the baffle assembly is disposed on the connecting portion. The baffle assembly, the connecting portion, and the cover form the mounting groove, and the connecting portion is provided with the first air outlet. The combined design of the cover and the connecting portion in the cover assembly makes the construction of the mounting groove more precise. The connecting portion, as an installation reference structure, can effectively position the baffle assembly. The mounting groove formed by the three provides a stable and suitable installation space for the ventilated component, ensuring that the relative position of the ventilated component with each component is accurate after installation, and ensuring the consistency of the gas flow path. At the same time, placing the first air outlet on the connecting portion can optimize the gas discharge path, making the gas flow direction more concentrated and smooth when discharged from the inside of the cleaning machine, reducing the residence time of the gas inside, effectively improving the gas discharge efficiency, and ensuring the internal air pressure balance and stable working environment of the cleaning machine.

[0007] In one embodiment, the cover has an installation opening, and the connecting part includes multiple connecting posts. These connecting posts are disposed on the cover and spaced circumferentially along the installation opening, with adjacent connecting posts forming the first air outlet. This design, where connecting posts are spaced circumferentially along the installation opening to form the first air outlet, serves two purposes: firstly, the connecting posts provide stable structural support, enhancing the overall strength of the mounting groove and effectively resisting vibrations and external impacts during the operation of the cleaning machine; secondly, the multiple spaced first air outlets significantly increase the number of gas discharge channels, multiplying the gas discharge efficiency compared to a single outlet and reducing the gas residence time inside the cleaning machine. Simultaneously, the circumferentially evenly distributed air outlets ensure uniform gas discharge from inside the cleaning machine, preventing localized pressure imbalances from adversely affecting the equipment.

[0008] In one embodiment, the cover includes an outer shell and an inner cover. The inner cover is disposed on the outer shell, and the connecting portion is disposed on the inner cover. The connecting portion is located on the side of the inner cover away from the outer shell. The outer shell, the inner cover, the connecting portion, and the baffle assembly enclose the mounting groove. The cover adopts a combined structure of an outer shell and an inner cover, which cooperate to form a stable and precise mounting base. During assembly, the outer shell and inner cover are installed in stages, reducing the complexity of the overall assembly, facilitating precise positioning of each component by the operator, and improving assembly efficiency. After the outer shell and inner cover are fitted together, they, together with the connecting portion and the baffle assembly, enclose the mounting groove. This multi-layered structure design significantly enhances the structural strength and sealing performance of the mounting groove. On the one hand, it provides a stable and reliable installation environment for the ventilated components, preventing displacement of the ventilated components due to vibration and other factors during the operation of the cleaning machine; on the other hand, good sealing performance can prevent gas leakage, ensuring that the gas inside the cleaning machine is discharged through the ventilated components according to a preset path, ensuring stable operation of the ventilated system, and improving the overall performance of the cleaning machine.

[0009] In one embodiment, the outer shell and the inner cover cooperate to form the mounting opening. The mounting opening, the connecting portion, and the baffle assembly surround to form the mounting groove. One of the outer shell and the inner cover has a sealing groove, or the outer shell and the inner cover cooperate to form a sealing groove. The sealing groove surrounds the mounting opening and is located between the outer shell and the inner cover. The cover also includes a sealing ring that is adapted to the sealing groove. The mating structure of the sealing groove and the sealing ring forms an effective sealing barrier between the outer shell and the inner cover. During the operation of the cleaning machine, it prevents internal gas from leaking from the connection between the outer shell and the inner cover, avoiding internal pressure instability caused by gas leakage, and preventing external dust, moisture, and other impurities from entering the cleaning machine, thus protecting internal components. Simultaneously, the elastic properties of the sealing ring can absorb installation errors and equipment operating vibrations to a certain extent, ensuring the long-term stability of the sealing effect and reducing equipment failure and maintenance costs due to seal failure.

[0010] In one embodiment, the outer shell has a plurality of first limiting protrusions, which are spaced apart circumferentially along the outer shell and located near the inner cover. Each first limiting protrusion has a recess at its end away from the outer shell. The inner cover has second limiting protrusions, which are spaced apart circumferentially along the inner cover and located near the outer shell. The second limiting protrusions are opposite to the first limiting protrusions and abut against the recess. This mating structure of the first and second limiting protrusions allows for rapid and accurate positioning during the installation of the outer shell and inner cover. The operator only needs to align the second limiting protrusion with the recess of the first limiting protrusion to complete the initial installation positioning, significantly reducing installation difficulty and improving assembly efficiency. During equipment operation, the abutting action between the limiting protrusions effectively restricts the relative displacement between the outer shell and inner cover, preventing component loosening due to vibration, ensuring the structural stability of the cover assembly, and maintaining the normal working state of the ventilated structure, thus avoiding obstruction of gas flow due to component displacement.

[0011] In one embodiment, the outer shell is provided with multiple first limiting members, and the inner cover is provided with multiple second limiting members. When the outer shell and the inner cover are fastened together, the multiple first limiting members correspond one-to-one with the multiple second limiting members and are interlocked. This one-to-one interlocking structure of the first and second limiting members establishes a high-strength connection between the outer shell and the inner cover through a mechanical snap-fit ​​mechanism. This connection method can withstand greater vibration and external forces during the operation of the cleaning machine, preventing the outer shell and inner cover from separating. Simultaneously, the snap-fit ​​connection structure provides clear tactile feedback during assembly, facilitating operator confirmation of proper installation and ensuring assembly quality. Furthermore, the interlocking limiting members can absorb vibration energy to a certain extent, reducing component fatigue damage caused by vibration transmission and extending the service life of the cover assembly.

[0012] In one embodiment, the first limiting member is located between adjacent first limiting protrusions, and the second limiting member is disposed on the second limiting protrusion. The first limiting member is composed of adjacent first grooves and first protrusions, and the second limiting member is composed of adjacent second grooves and second protrusions. The second grooves are adapted to the first protrusions, and the second protrusions are adapted to the first grooves. The groove-protrusion adaptation design of the first and second limiting members significantly improves the firmness of the connection between the outer shell and the inner cover by increasing the contact area and friction. During assembly, the cooperation between the grooves and protrusions can play a guiding role, reducing installation difficulty and improving assembly accuracy. At the same time, this fine structural design can effectively limit the relative displacement of the outer shell and the inner cover in multiple directions, and can maintain a stable connection even under the vibration and external force generated by the long-term operation of the cleaning machine, ensuring that the sealing and functionality of the ventilated structure are not affected.

[0013] In one embodiment, the outer shell has a mounting protrusion on the side near the inner cover, and the inner cover has multiple mounting keys on the side near the outer shell. These mounting keys are located between adjacent second limiting protrusions. The inner cover extends two adjacent ribs towards the outer shell. A connecting rib connects the two adjacent ribs, and the ribs, connecting ribs, and inner cover cooperate to form a sliding groove. When the outer shell and inner cover are installed, the mounting protrusion can engage with the sliding groove. This engagement structure of the mounting protrusion and sliding groove provides clear guidance and positioning for the installation of the outer shell and inner cover. During assembly, the mounting protrusion can smoothly slide into the engagement position along the sliding groove, reducing installation difficulty and improving assembly efficiency. Simultaneously, the mechanical locking effect of this structure effectively prevents relative sliding between the outer shell and inner cover due to vibration or external forces during equipment operation, ensuring the stability of the cover assembly structure. Furthermore, the mounting keys further enhance the strength and stability of the connection, distributing the force at the connection between the mounting protrusion and the sliding groove, and extending the service life of the connection structure.

[0014] In one embodiment, the outer shell has an annular protrusion along the circumference of the mounting opening, and the annular protrusion is located on the side close to the inner cover. The annular protrusion has a third limiting protrusion, and the connecting portion has a first limiting groove. The third limiting protrusion is adapted to the first limiting groove. When the outer shell and the inner cover are fastened together, the third limiting protrusion abuts against the first limiting groove. This matching structure of the third limiting protrusion and the first limiting groove strengthens the connection between the outer shell, the inner cover, and the connecting portion. During installation, the cooperation between the third limiting protrusion and the first limiting groove enables precise axial and circumferential positioning, ensuring accurate installation of each part of the cover assembly. During operation, the abutting action of both effectively transmits and disperses the forces between components, preventing structural deformation or loosening due to uneven stress. The annular protrusion, positioned circumferentially along the mounting opening, further enhances the structural strength of the mounting opening area, improves the overall rigidity of the cover assembly, and ensures stable operation of the ventilated structure under complex working conditions.

[0015] In one embodiment, the breathable component includes a breathable plate and a support protrusion. The support protrusion is disposed on the breathable plate and is at least partially located within the mounting groove. The support protrusion has multiple second air outlets spaced apart and opposite to the first air outlet. The first air outlet, the second air outlets, and the vent are sequentially connected. The breathable component employs a combination design of the breathable plate and the support protrusion. The support protrusion provides stable mounting support for the breathable plate, ensuring its fixed position within the mounting groove and preventing displacement due to vibration that could affect the breathability. The multiple spaced-apart second air outlets on the support protrusion, opposite to the first air outlets and connected to the vent, form a multi-stage gas flow channel. This design significantly increases the gas flow area, and compared to a single channel, it can significantly improve the gas discharge speed and efficiency. Simultaneously, the spaced-apart second air outlets ensure uniform gas distribution, guaranteeing the flow stability of the gas within the breathable component and optimizing the overall performance of the breathable structure.

[0016] In one embodiment, the supporting protrusion is provided with a fifth limiting protrusion, and one of the connecting portion and the baffle assembly is provided with a second limiting groove. The second limiting groove is adapted to the fifth limiting protrusion. When the ventilated assembly is installed on the cover assembly, the fifth limiting protrusion is engaged with the second limiting groove. The engaging structure of the fifth limiting protrusion and the second limiting groove provides a precise positioning reference for the installation of the ventilated assembly. During assembly, the operator can quickly and accurately install the ventilated assembly to the designated position using the limiting structure, reducing installation errors and improving assembly efficiency. During the operation of the cleaning machine, this limiting structure can effectively restrict the movement of the ventilated assembly in the mounting groove, prevent the ventilated assembly from shifting due to vibration, ensure the relative position stability of the ventilated assembly with components such as the first air outlet and the second air outlet, maintain the unobstructed gas flow path, and ensure the normal operation of the ventilated function of the cleaning machine.

[0017] In one embodiment, the ventilated component further includes a flow-blocking protrusion disposed on the ventilated plate and extending towards the baffle assembly, the flow-blocking protrusion being positioned opposite the second air outlet. The flow-blocking protrusion effectively obstructs the gas passing through the second air outlet, changing the gas flow direction and speed, resulting in a more uniform gas distribution within the ventilated structure. During the operation of the cleaning machine, this structure avoids localized pressure imbalances caused by excessively high gas flow rates or concentrated flow directions, preventing gas from impacting and damaging the ventilated component or other parts. Simultaneously, the obstruction effect of the flow-blocking protrusion can, to some extent, counteract the impact force of the gas on the ventilated component, preventing it from being pushed out of the mounting slot by the strong thrust of the airflow, ensuring the ventilated component is securely installed in its designated position. Furthermore, uniform gas distribution helps increase the contact area and contact time between the gas and the vent holes, enhancing the ventilation effect, ensuring more efficient gas discharge from inside the cleaning machine, and optimizing the overall performance of the ventilated structure.

[0018] In one embodiment, the connecting portion, the baffle assembly, and the venting assembly enclose a flow cavity. The formation of the flow cavity significantly increases the gas flow space within the venting structure, providing a buffer zone for gas flow. During operation, the larger flow space effectively reduces gas flow resistance, minimizes energy loss during gas flow, and allows gas to exit more smoothly through the venting structure, improving venting efficiency. Simultaneously, the flow cavity makes gas flow more stable within the structure, reducing noise caused by airflow turbulence and enhancing the comfort and stability of the cleaning machine's operation. Furthermore, the flow cavity can also accommodate a small amount of liquid generated by gas condensation, preventing liquid blockage of the gas flow channel and ensuring the normal operation of the venting system.

[0019] In one embodiment, the ventilated component further includes a first flow-through protrusion disposed on the ventilated plate and extending toward the baffle assembly. The first flow-through protrusion further optimizes the gas flow path within the ventilated component. By changing the gas flow direction and guiding gas diffusion, the gas can more fully contact various parts of the ventilated structure, increasing the contact area and contact time between the gas and the vent holes, thereby enhancing the ventilation effect. During the operation of the cleaning machine, this structure ensures efficient gas discharge from inside the cleaning machine, preventing internal pressure increases due to poor gas discharge, ensuring a stable internal working environment, and extending the equipment's service life. Simultaneously, the first flow-through protrusion also provides some turbulence to the gas, preventing the formation of eddies in localized areas and improving the uniformity and stability of gas flow. Furthermore, the structural design of the first flow-through protrusion can guide condensate generated during the ventilation process back to the baffle assembly, preventing condensate accumulation within the ventilated component, reducing damage to the ventilated structure caused by water accumulation, and ensuring long-term stable operation of the ventilated system.

[0020] In one embodiment, the baffle assembly protrudes towards the venting assembly at its center to form a second flow-through protrusion. The cross-section of the second flow-through protrusion is inclined from the center towards the first air outlet. This inclined cross-section design of the second flow-through protrusion not only precisely guides the gas, directing it smoothly towards the first air outlet, reducing flow resistance and improving gas discharge efficiency, but also effectively guides the condensate generated during the venting process back along the protrusion surface to the baffle assembly, preventing accumulation within the venting structure. This design optimizes the gas flow field, ensures unobstructed gas flow channels, reduces damage to the venting assembly from accumulated water, ensures stable operation of the venting system, and protects the internal components of the cleaning machine.

[0047] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention 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.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0049] The ventilation structure of the cleaning machine according to some embodiments of the present invention is described below with reference to the accompanying drawings.

[0050] like Figures 1 to 22 As shown, this embodiment discloses a ventilation structure for a cleaning machine. The ventilation structure includes: a cover assembly 1; a baffle assembly 2, which is disposed on the cover assembly 1 and forms an installation groove 101 with the cover assembly 1. The cover assembly 1 has a first air outlet 102 communicating with the installation groove 101 and is located on the side of the baffle assembly 2; and a ventilation assembly 3, which is detachably installed on the cover assembly 1 or the baffle assembly 2 and is at least partially located in the installation groove 101. The ventilation assembly 3 has a ventilation hole 301 communicating with the first air outlet 102.

[0051] This application discloses a ventilation structure for a cleaning machine. A complete ventilation system is constructed through the cooperation of a cover assembly 1, a baffle assembly 2, and a ventilation assembly 3. The detachable ventilation assembly 3 facilitates quick replacement and cleaning during equipment maintenance or when the ventilation hole 301 becomes clogged, reducing equipment maintenance costs and downtime. The first air outlet 102 communicates with the ventilation hole 301, optimizing the gas discharge path, reducing flow resistance, preventing excessive internal air pressure and water vapor condensation, and protecting internal components. The mounting groove 101 formed by the cover assembly 1 and the baffle assembly 2 is adapted to the ventilation assembly 3, preventing the ventilation assembly 3 from shifting due to airflow impact; simultaneously, the reasonable layout blocks external dust and impurities from entering, ensuring stable ventilation function.

[0052] like Figures 1 to 7 As shown, in addition to the features of the above embodiments, this embodiment further defines: the cover assembly 1 includes a cover 11 and a connecting part 12. The connecting part 12 is disposed on the cover 11, and the baffle assembly 2 is disposed on the connecting part 12. The baffle assembly 2, the connecting part 12, and the cover 11 enclose to form an installation groove 101. The connecting part 12 is provided with a first air outlet 102. The combined design of the cover 11 and the connecting part 12 in the cover assembly 1 makes the construction of the installation groove 101 more precise. The connecting part 12 serves as an installation reference structure and can effectively position the baffle assembly 2. The installation groove 101 formed by the three components can provide a stable and suitable installation space for the ventilated assembly 3, ensuring that the relative position of the ventilated assembly 3 with each component is accurate after installation, and ensuring the consistency of the gas flow path. Meanwhile, by setting the first air outlet 102 on the connecting part 12, the gas discharge path can be optimized, making the flow direction of the gas more concentrated and smooth when it is discharged from the inside of the cleaning machine, reducing the residence time of the gas inside, effectively improving the gas discharge efficiency, and ensuring the internal air pressure balance and stable working environment of the cleaning machine.

[0053] In addition to the features of the above embodiments, this embodiment further specifies that: the cover 11 has an installation port 1101, and the connecting part 12 includes a plurality of connecting posts 121. The plurality of connecting posts 121 are disposed on the cover 11 and spaced apart circumferentially along the installation port 1101, with a first air outlet 102 formed between adjacent connecting posts 121. The design of the connecting posts 121 spaced apart circumferentially along the installation port 1101 to form the first air outlet 102 has two advantages. First, the connecting posts 121 provide stable structural support, enhancing the overall strength of the mounting groove 101 and effectively resisting vibration and external impact during the operation of the cleaning machine. Second, the multiple spaced first air outlets 102 significantly increase the number of gas discharge channels, which can multiply the gas discharge efficiency compared to a single air outlet and reduce the residence time of gas inside the cleaning machine. At the same time, the circumferentially evenly distributed air outlets can ensure that the gas inside the cleaning machine is discharged evenly, avoiding the adverse effects of local pressure imbalance on the equipment.

[0054] In addition to the features of the above embodiments, this embodiment further specifies that: the cover 11 includes an outer shell 111 and an inner cover 112, the inner cover 112 is disposed on the outer shell 111, and the connecting part 12 is disposed on the inner cover 112, with the connecting part 12 located on the side of the inner cover 112 away from the outer shell 111. The outer shell 111, the inner cover 112, the connecting part 12, and the baffle assembly 2 enclose and form a mounting groove 101. The cover 11 adopts a combined structure of the outer shell 111 and the inner cover 112, which cooperate with each other to form a stable and precise mounting base. During the assembly process, the outer shell 111 and the inner cover 112 are installed in stages, which reduces the complexity of the overall assembly, facilitates the operator to accurately position each component, and improves assembly efficiency. After the outer shell 111 and the inner cover 112 are fitted together, they together with the connecting part 12 and the baffle assembly 2 enclose and form the mounting groove 101. This multi-layered structure design significantly enhances the structural strength and sealing performance of the mounting groove 101. On the one hand, it can provide a stable and reliable installation environment for the ventilated component 3, preventing the ventilated component 3 from shifting due to vibration and other factors during the operation of the cleaning machine; on the other hand, good sealing can prevent gas leakage, ensure that the gas inside the cleaning machine is discharged through the ventilated component 3 according to the preset path, ensure the stable operation of the ventilated system, and improve the overall performance of the cleaning machine.

[0055] In addition to the features of the above embodiments, this embodiment further specifies that: the outer shell 111 and the inner cover 112 cooperate to form an installation port 1101; the installation port 1101, the connecting part 12, and the baffle assembly 2 enclose to form an installation groove 101; one of the outer shell 111 and the inner cover 112 is provided with a sealing groove 11201, or the outer shell 111 and the inner cover 112 cooperate to form a sealing groove 11201; the sealing groove 11201 is arranged around the installation port 1101 and located between the outer shell 111 and the inner cover 112; the cover 11 also includes a sealing ring 113, which is adapted to the sealing groove 11201. The cooperation structure of the sealing groove 11201 and the sealing ring 113 forms an effective sealing barrier between the outer shell 111 and the inner cover 112. During the operation of the cleaning machine, it can prevent internal gas from leaking from the connection between the outer shell 111 and the inner cover 112, avoid internal pressure instability caused by gas leakage, and prevent external dust, water vapor, and other impurities from entering the cleaning machine, thus protecting the internal components. Meanwhile, the elastic properties of the sealing ring 113 can absorb installation errors and equipment operation vibrations to a certain extent, ensuring the long-term stability of the sealing effect and reducing equipment failure and maintenance costs caused by sealing failure.

[0056] like Figures 6 to 16As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the outer shell 111 is provided with a plurality of first limiting protrusions 1111, the plurality of first limiting protrusions 1111 are arranged at intervals along the circumference of the outer shell 111 and located on the side near the inner cover 112, and the end of the first limiting protrusion 1111 away from the outer shell 111 is provided with a recess; the inner cover 112 is provided with a second limiting protrusion 1121, the second limiting protrusion 1121 is arranged at intervals along the circumference of the inner cover 112 and located on the side near the outer shell 111, the second limiting protrusion 1121 is arranged opposite to the first limiting protrusion 1111, and the second limiting protrusion 1121 abuts against the recess. The mating structure of the first limiting protrusion 1111 and the second limiting protrusion 1121 can achieve rapid and accurate positioning during the installation of the outer shell 111 and the inner cover 112. The operator only needs to align the second limiting protrusion 1121 with the recess of the first limiting protrusion 1111 to complete the initial installation positioning, significantly reducing installation difficulty and improving assembly efficiency. During equipment operation, the abutting action between the limiting protrusions can effectively limit the relative displacement between the outer shell 111 and the inner cover 112, preventing component loosening due to vibration, ensuring the structural stability of the cover assembly 1, and thus maintaining the normal working state of the ventilated structure, avoiding obstruction of gas flow due to component displacement.

[0057] In addition to the features of the above embodiments, this embodiment further specifies that: the outer shell 111 is provided with a plurality of first limiting members 1112, and the inner cover 112 is provided with a plurality of second limiting members 1122. When the outer shell 111 and the inner cover 112 are fastened together, the plurality of first limiting members 1112 and the plurality of second limiting members 1122 correspond one-to-one and are fastened together. The structure in which the first limiting members 1112 and the second limiting members 1122 are fastened together establishes a high-strength connection between the outer shell 111 and the inner cover 112 through a mechanical snap-fit ​​method. This connection method can withstand greater vibration and external force during the operation of the cleaning machine, preventing the outer shell 111 and the inner cover 112 from separating. At the same time, the snap-fit ​​connection structure has obvious tactile feedback during assembly, making it easy for operators to confirm that the installation is in place and ensuring assembly quality. In addition, the fastened limiting members can also absorb vibration energy to a certain extent, reducing component fatigue damage caused by vibration transmission and extending the service life of the cover assembly 1.

[0058] In addition to the features of the above embodiments, this embodiment further specifies that: the first limiting member 1112 is located between adjacent first limiting protrusions 1111, and the second limiting member 1122 is disposed on the second limiting protrusion 1121; the first limiting member 1112 is composed of adjacent first grooves and first protrusions, and the second limiting member 1122 is composed of adjacent second grooves and second protrusions, with the second grooves and first protrusions adapted to each other. The groove-protrusion adaptation design of the first limiting member 1112 and the second limiting member 1122 significantly improves the firmness of the connection between the outer shell 111 and the inner cover 112 by increasing the contact area and friction. During assembly, the cooperation between the grooves and protrusions can play a guiding role, reducing the installation difficulty and improving the assembly accuracy. At the same time, this fine structural design can effectively limit the relative displacement of the outer shell 111 and the inner cover 112 in multiple directions, and can maintain a stable connection even under the vibration and external force generated by the long-term operation of the cleaning machine, ensuring that the sealing and functionality of the ventilated structure are not affected.

[0059] In addition to the features of the above embodiments, this embodiment further specifies that: the outer shell 111 has a mounting protrusion 1113 on the side near the inner cover 112, and the inner cover 112 has a plurality of mounting keys 1123 on the side near the outer shell 111. The plurality of mounting keys 1123 are located between adjacent second limiting protrusions 1121. The inner cover 112 extends two ribs toward the outer shell 111. The two ribs are adjacent and also include a connecting rib. The connecting rib connects the two adjacent ribs. The ribs, connecting ribs and inner cover 112 cooperate to form a sliding groove. When the outer shell 111 and inner cover 112 are installed, the mounting protrusion 1113 can be snapped into the sliding groove. The snapping structure of the mounting protrusion 1113 and the sliding groove provides a clear guiding and positioning function for the installation of the outer shell 111 and inner cover 112. During the assembly process, the mounting protrusion 1113 can slide smoothly into the snapping position along the sliding groove, reducing the installation difficulty and improving the assembly efficiency. Meanwhile, the mechanical locking effect created by this structure effectively prevents the outer shell 111 and the inner cover 112 from sliding relative to each other due to vibration or external force during equipment operation, ensuring the structural stability of the cover assembly 1. In addition, the installation key 1123 further enhances the strength and stability of the connection part 12, distributes the force at the connection between the installation protrusion 1113 and the slide groove, and extends the service life of the connection structure.

[0060] In addition to the features of the above embodiments, this embodiment further specifies that: the outer shell 111 is provided with an annular protrusion along the circumference of the mounting opening 1101, and the annular protrusion is located on the side close to the inner cover 112. A third limiting protrusion 1114 is provided on the annular protrusion, and a first limiting groove 1201 is provided on the connecting portion 12. The third limiting protrusion 1114 is adapted to the first limiting groove 1201. When the outer shell 111 and the inner cover 112 are fastened together, the third limiting protrusion 1114 abuts against the first limiting groove 1201. The adaptation structure of the third limiting protrusion 1114 and the first limiting groove 1201 strengthens the connection between the outer shell 111, the inner cover 112, and the connecting portion 12. During installation, the cooperation between the third limiting protrusion 1114 and the first limiting groove 1201 enables precise axial and circumferential positioning, ensuring that the installation positions of each part of the cover assembly 1 are accurate. During equipment operation, the contact action between the two components effectively transmits and disperses the forces between them, preventing structural deformation or loosening caused by uneven stress. The annular protrusion is arranged circumferentially along the mounting opening 1101, further enhancing the structural strength of the mounting opening 1101, improving the overall rigidity of the cover assembly 1, and ensuring the stable operation of the ventilated structure under complex working conditions.

[0061] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 17 , Figure 18 , Figure 19 , Figure 20 , Figure 21 and Figure 22As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the breathable component 3 includes a breathable plate 31 and a support protrusion 32. The support protrusion 32 is disposed on the breathable plate 31 and is at least partially located within the mounting groove 101. The support protrusion 32 has multiple second air outlets 302, which are spaced apart and opposite to the first air outlet 102. The first air outlet 102, the second air outlets 302, and the vent holes 301 are sequentially connected. The breathable component 3 adopts a combination design of the breathable plate 31 and the support protrusion 32. The support protrusion 32 provides stable installation support for the breathable plate 31, ensuring that the position of the breathable plate 31 within the mounting groove 101 is fixed and avoiding displacement due to vibration that could affect the breathability. The multiple spaced-apart second air outlets 302 on the support protrusion 32 are opposite to the first air outlet 102 and connected to the vent holes 301, forming a multi-stage gas flow channel. This design significantly increases the gas flow area, which can greatly improve the gas discharge speed and efficiency compared to a single channel. At the same time, the spaced second air outlets 302 can ensure uniform gas distribution, guarantee the flow stability of gas within the breathable component 3, and optimize the overall performance of the breathable structure.

[0062] In addition to the features of the above embodiments, this embodiment further specifies that: the support protrusion 32 is provided with a fifth limiting protrusion 321, and one of the connecting part 12 and the baffle assembly 2 is provided with a second limiting groove 1202. The second limiting groove 1202 is adapted to the fifth limiting protrusion 321. When the ventilated assembly 3 is installed on the cover assembly 1, the fifth limiting protrusion 321 is engaged at the second limiting groove 1202. The matching and engaging structure of the fifth limiting protrusion 321 and the second limiting groove 1202 provides a precise positioning reference for the installation of the ventilated assembly 3. During the assembly process, the operator can quickly and accurately install the ventilated assembly 3 to the designated position through the limiting structure, reducing installation errors and improving assembly efficiency. During the operation of the cleaning machine, the limiting and locking structure can effectively restrict the movement of the ventilating component 3 in the mounting groove 101, prevent the ventilating component 3 from shifting due to vibration, ensure the relative position of the ventilating component 3 with components such as the first air outlet 102 and the second air outlet 302 is stable, maintain the smooth flow of gas, and ensure the normal realization of the ventilating function of the cleaning machine.

[0063] In addition to the features of the above embodiments, this embodiment further specifies that: the air-permeable component 3 also includes a flow-blocking protrusion 33, which is disposed on the air-permeable plate 31 and extends towards the baffle assembly 2, and is disposed opposite to the second air outlet 302. The flow-blocking protrusion 33 can effectively obstruct the gas passing through the second air outlet 302, and by changing the flow direction and speed of the gas, the gas distribution within the air-permeable structure is made more uniform. During the operation of the cleaning machine, this structure can avoid local pressure imbalance caused by excessively fast gas flow or concentrated flow direction, and prevent the gas from impacting and damaging the air-permeable component 3 or other components. At the same time, the obstruction effect of the flow-blocking protrusion 33 on the gas can, to a certain extent, offset the impact force of the gas on the air-permeable component 3, preventing the air-permeable component 3 from being pushed out of the mounting groove 101 by the strong thrust of the airflow, and ensuring that the air-permeable component 3 is stably installed in the predetermined position. In addition, uniform gas distribution helps to increase the contact area and contact time between the gas and the vent 301, enhance the ventilation effect, ensure that the gas inside the cleaning machine can be discharged more efficiently, and optimize the overall performance of the ventilation structure.

[0064] In addition to the features of the above embodiments, this embodiment further defines that the connecting part 12, the baffle assembly 2, and the venting assembly 3 enclose a flow cavity 303. The formation of the flow cavity 303 significantly increases the flow space of gas within the venting structure, providing a buffer area for gas flow. When the cleaning machine is working, the larger flow space can effectively reduce gas flow resistance, reduce energy loss during gas flow, and allow gas to be discharged more smoothly through the venting structure, improving venting efficiency. At the same time, the flow cavity 303 can make the gas flow within the structure more stable, reduce noise caused by airflow turbulence, and improve the comfort and stability of the cleaning machine operation. In addition, the flow cavity 303 can also accommodate a small amount of liquid generated by gas condensation to a certain extent, preventing liquid from blocking the gas flow channel and ensuring the normal operation of the venting system.

[0065] In addition to the features of the above embodiments, this embodiment further specifies that the ventilated component 3 also includes a first flow-through protrusion 34, which is disposed on the ventilated plate 31 and extends toward the baffle assembly 2. The arrangement of the first flow-through protrusion 34 further optimizes the flow path of gas within the ventilated component 3. By changing the gas flow direction and guiding gas diffusion, the gas can more fully contact various parts of the ventilated structure, increasing the contact area and contact time between the gas and the vent holes 301, thereby enhancing the ventilation effect. During the operation of the cleaning machine, this structure can ensure that the gas inside the cleaning machine can be efficiently discharged, avoiding the increase in internal pressure caused by poor gas discharge, ensuring a stable internal working environment for the cleaning machine, and extending the service life of the equipment. At the same time, the first flow-through protrusion 34 can also play a certain role in turbulence of the gas, preventing the formation of eddies in local areas and improving the uniformity and stability of gas flow. In addition, the structural design of the first flow-through protrusion 34 can also guide the condensate generated during the ventilation process back to the baffle assembly 2, avoid the accumulation of condensate in the ventilation assembly 3, reduce the damage to the ventilation structure caused by water accumulation, and ensure the long-term stable operation of the ventilation system.

[0066] In addition to the features of the above embodiments, this embodiment further specifies that: the middle part of the baffle assembly 2 protrudes towards the ventilated assembly 3 to form a second flow-through protrusion 21, and the cross-section of the second flow-through protrusion 21 is inclined from the middle towards the first air outlet 102. The inclined cross-section design of the second flow-through protrusion 21 not only provides precise guidance for the gas, guiding the gas to flow smoothly towards the first air outlet 102, reducing flow resistance and improving gas discharge efficiency; it also effectively guides the condensate generated during the ventilation process to flow back along the protruding surface to the baffle assembly 2, avoiding accumulation within the ventilated structure. This design optimizes the gas flow field, ensures unobstructed gas flow channels, reduces damage to the ventilated assembly 3 from accumulated water, ensures stable operation of the ventilated system, and protects the internal components of the cleaning machine.

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.
