Description

Technical Field

[0001] This invention relates to the field of cleaning containers for kitchen cleaning, specifically a cleaning device that can be used as a cleaning container and can automatically clean fruits, vegetables, fish, meat, and other food ingredients. Background Technology

[0002] For Chinese kitchens, the abundance of ingredients makes the need for cleaning fruits, vegetables, fish, and meats very high. Currently, people mostly use washing containers to clean these items, which is time-consuming and laborious. To address this issue, the applicant's prior patent ZL201610632336.9, "Integrated Washing Container Washing Device," discloses a structure that integrates a separate fruit and vegetable washing machine next to the washing container. While this provides convenience for users cleaning fruits, vegetables, fish, and meats, the drainage components and the drive structure of the washing machine are all located at the bottom of the washing container, severely limiting the height and volume of both the washing machine and the washing container, thus affecting the independent usable space of the washing container.

[0003] Paper ZL201821326601.1, "A Washing Container-Type Washing Machine with Fruit and Vegetable Washer," discloses a structure that integrates a washing container and a dishwasher, with a detachable and movable fruit and vegetable washer installed within the washing container. While this structure provides convenience for independent washing of fruits and vegetables, the spray nozzles of the fruit and vegetable washer actually use the same spray arm structure as the original washing container washer, and the water supply to the spray nozzles requires the original washing container washer's water supply system. This necessitates a structure on the side of the washing container that can connect to the original washing container's water supply system. However, due to the fruit and vegetable washer's own weight and the vibration or water flow impact generated when water enters from the side, there is a slight displacement. The connection structure is difficult to balance between easy connection and sealing performance, easily leading to fluid leakage, which in turn affects the medium pressure and cleaning effect. Furthermore, existing interlocking sealing structures struggle to balance sealing performance and reliable connection during frequent disassembly and reassembly.

[0004] Therefore, the current integrated cleaning structure of cleaning containers and automatic cleaning machines needs further improvement. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a cleaning device that is easy to disassemble and assemble and has good sealing at the connection points, in light of the current state of the prior art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] A cleaning device includes a cleaning container and a cleaning tank detachably disposed in the cleaning container. The cleaning container is further provided with a media delivery module for delivering a medium to the cleaning tank. The cleaning tank and the media delivery module are connected in a flexible sealed manner through a connector. The cleaning device also includes a positioning structure that can lock the cleaning tank and the media delivery module after assembly.

[0008] Preferably, the cleaning tank and the media conveying module form a first interface and a second interface that can be connected to each other for conveying fluid, and the first interface and the second interface are fluidly connected through a connector. This structure facilitates a detachable connection between the cleaning tank and the media conveying module through the connector.

[0009] Preferably, the connector has a sealing section extending from the first interface to the second interface and capable of axial elastic expansion and contraction, the head of which forms a flexible seal with the second interface. With this structure, during media flow, the connection can automatically expand and contract according to the media pressure, maintaining good sealing performance and ensuring high sealing reliability.

[0010] Preferably, a boss is provided on the periphery of the interface opposite to the sealing section, and the outer end face of the sealing section is elastically pressed against the boss. Providing a boss structure can shorten the mating distance for the flexible sealing structure and provide a stable sealing surface, which is beneficial to improving the compactness and reliability of the sealing structure.

[0011] Preferably, the cleaning tank has a first interface on its side, and the media conveying module has a second interface on its side. The sealing section is used to form an elastic compression seal between the first and second interfaces. With this structure, during media flow, the connection can expand and contract according to the media pressure, maintaining good sealing performance and ensuring high sealing reliability.

[0012] Preferably, the positioning structure is used to form a dynamic seal between the sealing section and the second interface. Under fluid flow conditions in the sealing section, the positioning structure constrains a displacement range that allows the sealing section to elastically expand and contract while maintaining a seal. This positioning structure allows the flexible sealing structure to form a dynamic seal, enabling it to expand and contract with changes in water pressure, thus adaptively adapting to the water pressure and improving sealing performance. The constraint of the displacement range ensures that the flexible sealing structure can expand and contract within a certain range, further improving the reliability of the seal.

[0013] Preferably, the sealing section is a bellows section.

[0014] Preferably, the positioning structure includes a first part and a second part, wherein the first part is disposed on the cleaning tank or connector, and the second part is disposed on the side wall of the media conveying module or cleaning container; or, the first part is disposed on the side wall of the media conveying module or cleaning container, and the second part is disposed on the cleaning tank or connector. This structure facilitates detachable connection.

[0015] Preferably, the positioning structure includes a latch and a hook, wherein one of the latch and the hook constitutes the first part, and the other constitutes the second part, and the latch and the hook are detachably plugged into each other. This structure facilitates plug-in connection.

[0016] Preferably, the latch is a V-shaped structure with an outward opening. Rollers capable of rolling engagement are provided at both ends of the V-shaped structure. The latch hook is arrow-shaped. During docking, the outer bevel of the arrowhead of the latch hook rolls between the two rollers and extends into the inner cavity of the V-shaped structure. After docking, the inner end face of the arrowhead of the latch hook forms a rolling stop with the surfaces of the two rollers in the inner cavity of the V-shaped structure. This structure facilitates pre-positioning during mouth-to-mouth docking and is also convenient for disassembly; separation can be achieved by overcoming the elasticity of the V-shaped latch, making operation easy. The force connecting the V-shaped latch and the arrowhead-shaped latch hook simultaneously applies pressure to the flexible sealing end face, further increasing the sealing performance. During media transport, the inner end face of the arrowhead of the latch hook forms a rolling stop with the surfaces of the two rollers in the inner cavity of the V-shaped structure, allowing for a certain amount of elastic expansion and contraction in the axial direction of the flexible sealing structure to achieve adaptive sealing at the interface.

[0017] Preferably, the connector is provided with an air inlet for air supply and a water outlet for water supply and / or drainage. The media conveying system has interfaces corresponding to the air inlet and water outlet, respectively. The air inlet and water outlet are detachably sealed to their corresponding interfaces via sealing sections. The positioning structure is located between the air inlet and the water outlet. The air inlet and water outlet are symmetrically distributed on the positioning structure to ensure reliable sealing of the interfaces after the locking connection, preventing water leakage. Through pre-positioning and locking connection, a synchronous and reliable sealing connection of the two interfaces is achieved, meeting the user's requirement for long-term reliable sealing of the interfaces under a pull-out force of up to 20N. At the same time, compared with electrified interface actuators, it achieves low cost and high reliability.

[0018] In a preferred embodiment of the sealing end and interface, when the first and second interfaces are connected, the head of the sealing section passes through the second interface and is located within the media supply channel of the media delivery system. The media delivery system sidewall surrounding the second interface is engaged in the trough groove on the outer periphery of the sealing section. This structure ensures that the connection maintains good sealing performance in the connected state.

[0019] Preferably, the head end face of the sealing section forms a slope that gradually inclines radially inward from its edge toward the media delivery system. Preferably, the slope constitutes a guide surface that guides the inner edge of the second interface during the mating process of the sealing section and the second interface. With this structure, the head of the sealing section can be guided during mating, and uniform pressure can be applied to the head of the sealing section through the second interface, thereby accurately inserting the head of the sealing section into the second interface.

[0020] Preferably, the second interface is located at the end of the media supply channel, and the inclined surface forms a guide surface that can converge the incoming water from the media supply channel radially towards the center of the second interface. At the end of the media supply channel, since the media needs to undergo a 90-degree bend and reversal at the second interface, there is usually a problem of turbulent media flow and large pressure loss. By adopting the above structure, the head of the sealing section is used to converge and guide the fluid at the reversal point, which helps to reduce fluid loss and improve the cleaning effect.

[0021] Preferably, in the medium conveying state, the sidewall of the medium conveying system surrounding the second interface dynamically cooperates with the trough to form an adaptive sealing structure that can expand and contract with changes in medium pressure. This invention forms a detachable elastic seal. The second interface seal employs an elastic sealing structure, ensuring excellent smooth left-right sliding of the cleaning tank. Furthermore, the sealing section provides sufficient sealing elasticity and elastic deformation. When the cleaning tank is filled with water, the higher the water pressure, the better the sealing effect. Even during changes in water pressure, a good adaptive sealing effect is maintained.

[0022] Preferably, the outer wall of the media conveying system is provided with a raised ring arranged around the second interface. The inner surface of the second interface is inclined radially from the outside to the inside along the water flow direction to form a mating surface. The raised ring elastically engages with the first inclined surface of the trough, and the mating surface elastically engages with the second inclined surface of the trough. With this structure, a pressure seal with a small mating area is provided at the first inclined surface of the trough, while a contact seal with a large mating area is provided at the second inclined surface of the trough. The combination of these two provides high sealing performance while facilitating adaptive engagement of the sealing structure with changes in water pressure.

[0023] Preferably, the side wall of the cleaning tank is provided with a slot communicating with the first interface, the connector is disposed in the slot, and a plug-in sleeve is provided on the outer side of the connector. The sealing section is formed on the outer wall of the plug-in sleeve, directly disposed on the side wall of the cleaning tank, or connected to the side wall of the cleaning tank through a plug-in assembly. The connector is made of rigid plastic, while the plug-in sleeve is made of a material that is easily elastically deformable to achieve an elastic seal. The connector and the plug-in sleeve together constitute the connector.

[0024] As another preferred embodiment of the sealing end and interface, when the first interface and the second interface are in communication, the outer end face of the sealing segment is elastically pressed against the outer surface of the second interface. In its natural state, the axial length of the sealing segment is greater than the distance between the first and second interfaces. Therefore, after the cleaning tank is moved into place, the sealing segment is elastically compressed between the first and second interfaces to form a seal. This structure is easy to assemble, and the connection point has low structural requirements, making it easy to manufacture.

[0025] Preferably, the side wall of the cleaning container has a notch for the first interface and the second interface to connect opposite each other, and at least a portion of the connector passes through the notch. More preferably, at least a portion of the second interface is hidden within the notch, and the periphery of the first interface has a mating structure that can be inserted into at least a portion of the notch and engages with the inclined surface of the inner wall of the notch. In this invention, the sealing structure around the first interface forms an inclined surface that gradually slopes inward from the first interface. Correspondingly, the inner wall of the notch can be a normally extending wall surface or a mating inclined surface that matches this inclined surface. This structure can serve a guiding function when the sealing sections are joined and sealed.

[0026] Preferably, the side of the cleaning tank is provided with a support rib, which supports the cleaning tank in the cleaning container. This structure facilitates the support of the cleaning tank in the water tank.

[0027] Compared with the prior art, the advantages of this invention are as follows: This invention achieves a flexible sealing connection between the cleaning tank and the media conveying module through a connector. Because the flexible structure has a certain axial expansion and contraction force, it can generate a certain axial expansion and contraction margin. During media flow, the connection can self-expand and fit according to the media pressure, always maintaining good sealing performance and high sealing reliability. During assembly, the positioning structure can pre-position the flexible sealing connection structure, thereby ensuring that there is no deviation at the flexible sealing connection and maintaining the seal more precisely. After assembly, if the water pressure changes significantly during media conveying, the positioning structure can maintain the flexible sealing connection through its positioning action, preventing it from detaching and improving sealing reliability.

Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] In the description of this invention, it should be understood that if terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limiting this invention.

[0045] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Where applicable, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this invention are for illustrative purposes only and do not represent the only possible implementation.

[0049] Example 1:

[0050] like Figure 1 As shown in ~ 11, the cleaning device of this embodiment includes a water tank 1 and a cleaning tank 2 detachably disposed in the water tank 1. A drain outlet 13 is provided on the bottom wall of the water tank 1, and a medium conveying system 100 for supplying water and / or air to the cleaning tank 2 is provided outside the water tank 1.

[0051] In existing methods of combining a washing tank with a sink or a sink dishwasher, the washing tank occupies the space of the sink. This embodiment provides a washing tank 2 that can be combined with or separated from the sink 1. When combined with the sink 1, it is an electric washing tank. When separated from the sink 1, it reverts to an independent large sink 1 to meet the different cleaning needs of users.

[0052] The side of the cleaning tank 2 is provided with a first interface 200 that can be connected or disconnected from the media conveying system 100. The media conveying system 100 is provided with a second interface 20 corresponding to the first interface 200. A sealing section 3 extending outward and capable of axial elastic expansion and contraction is provided at the first interface 200. The sealing section 3 is detachably connected to the second interface 20. With the above structure, the sealing section 3 has a certain axial expansion and contraction force. When it is connected to the second interface 20, its head can be inserted into the second interface 20 by means of its axial elasticity. The edge of the second interface 20 just forms a snap-fit ​​limit with the recessed part on the outside of the sealing section 3. This connection structure is not only convenient for disassembly and assembly, but also, because the connection has a certain axial expansion and contraction margin, the connection can expand and contract with the medium pressure during the medium flow process, always maintaining good sealing performance.

[0053] In this embodiment, with the first interface 200 and the second interface 20 connected, the head of the sealing section 3 passes through the second interface 20 and is located within the medium supply channel 001 of the medium delivery system 100. The side wall of the medium delivery system 100 surrounding the second interface 20 is engaged in the trough 31 on the outer periphery of the sealing section 3. This structure ensures that the connection maintains good sealing performance in the connected state.

[0054] The head end face of the aforementioned sealing section 3 forms a slope 30 that gradually inclines radially inward from its edge toward the media delivery system 100. This slope 30 serves as a guide surface that guides the inner edge of the second interface 20 during the insertion process of the sealing section 3 and the second interface 20. With this structure, the head of the sealing section 3 can be guided during insertion, and uniform pressure can be applied to the head of the sealing section 3 through the second interface 20, thereby accurately inserting the head of the sealing section 3 into the second interface 20.

[0055] In this embodiment, the second interface 20 is located at the end of the medium supply channel 001, and the inclined surface 30 forms a guide surface that can converge the incoming water from the medium supply channel 001 radially towards the center of the second interface 20. At the end of the medium supply channel 001, since the medium needs to undergo a 90-degree bend and change of direction through the second interface 20, there is usually a problem of turbulent medium flow and large pressure loss. By adopting the above structure, the head of the sealing section 3 is used to converge and guide the fluid at the reversal point, which helps to reduce fluid loss and improve the cleaning effect.

[0056] In this embodiment, during media delivery, the sidewall of the media delivery system 100 surrounding the second interface 20 and the corrugated groove 31 dynamically cooperate to form an adaptive sealing structure that can expand and contract with changes in media pressure. This embodiment forms a detachable elastic seal. The second interface seal adopts a corrugated elastic sealing structure, which ensures that the cleaning tank 2 has good left and right sliding smoothness. Furthermore, the corrugated structure provides sufficient sealing elasticity and elastic deformation. When the cleaning tank 2 is filled with water, the higher the water pressure, the better the sealing effect. Even during changes in water pressure, a good adaptive sealing effect can always be maintained.

[0057] In this embodiment, the outer wall of the media conveying system 100 is provided with a convex ring 101 arranged around the second interface 20. The inner surface of the second interface 20 is inclined radially from the outside to the inside in the direction of water flow to form a mating surface 102. The convex ring 101 elastically engages with the first inclined surface 311 of the trough 31, and the mating surface 102 elastically engages with the second inclined surface 312 of the trough 31. With the above structure, a pressure seal with a small mating surface area 102 is provided at the first inclined surface 311 of the trough 31, and a contact seal with a large mating surface area 102 is provided at the second inclined surface 312 of the trough 31. The two work together to achieve high sealing performance while facilitating adaptive engagement of the sealing structure with changes in water pressure.

[0058] The aforementioned sealing section 3 includes 2 to 3 corrugated structures 32 that are sequentially connected along the axial direction and protrude outwards, with a trough 31 formed between two adjacent corrugated structures 32. Too many corrugated structures will cause some loss of water flow energy. In this embodiment, it is preferred to have 2 corrugated structures, that is, the sealing section 3 constitutes a double corrugated elastic sealing structure, so as to balance low energy loss and sufficient elastic sealing.

[0059] In this embodiment, a positioning structure 300 is also provided between the cleaning tank 2 and the media conveying system 100, which can pre-position the two during assembly and lock them after assembly. This structure allows for pre-positioning during assembly before the head of the sealing section 3 is engaged with the second interface 20, ensuring no deviation between the head of the sealing section 3 and the second interface 20, achieving more precise insertion and reducing compression loss on the sealing section 3. After assembly, if there are significant changes in water pressure during media conveying, the positioning structure 300 can maintain the sealing seal between the sealing section 3 and the second interface 20 through its positioning function, preventing them from separating.

[0060] The side of the cleaning tank 2 is provided with an air inlet 21 for supplying air and a water outlet 22 for supplying water and / or draining water. The cleaning tank 2 is provided with an air passage and aeration hole connected to the air inlet 21, and a flow channel and spray hole connected to the water outlet 22, so as to form air blowing and turbulence in the cleaning tank 2 to clean the food in the cleaning tank 2.

[0061] The medium conveying system 100 is flat and is installed on the outer wall of the water tank 1. The medium conveying system 100 is provided with an air inlet pipe that can be connected to the air inlet 21, a water inlet pipe that can be connected to the water outlet 22, and a drainage pipe. The side wall of the water tank 1 is provided with a notch 11 for the air inlet 21 and the water outlet 22 to connect with the corresponding pipes.

[0062] In this embodiment, the inner sidewall of the water tank 1 is provided with a laterally extending guide rib 12. Correspondingly, the sidewall of the cleaning tank 2 is formed with a guide portion 25 that can reciprocate and slide against the guide rib. This structure is adopted to realize the lateral sliding of the cleaning tank 2 in the water tank 1. The main body of the cleaning tank 2 has a vertically extending sidewall, and the bottom of the cleaning tank 2 is formed into a bowl-shaped or flat-bottomed pot-shaped structure that smoothly transitions inward from the bottom edge of the sidewall. The connection between the sidewall and the bottom of the cleaning tank 2 forms a guide portion 25 that can slide and support the guide rib 12. By placing the guide portion 25 here, that is, moving the support position between the cleaning tank 2 and the water tank 1 to the lower part of the cleaning tank 2, the sliding stability of the cleaning tank 2 can be improved, and the reliability of the cleaning tank 2 when bearing weight can be improved.

[0063] In this embodiment, the cleaning tank 2 is detachably installed in the water tank 1. When the cleaning tank 2 is needed, it is placed in the water tank 1, and water and air are introduced into the cleaning tank 2 through the media conveying system 100 to achieve cleaning. When the cleaning tank 2 is not needed, it can be removed from the water tank 1, so that the water tank 1 has a large volume of cleaning space to meet user needs. In addition, the media conveying system 100 is located on the outer wall of the water tank 1, so it does not occupy the space at the bottom of the water tank 1 like existing water tank 1 dishwashers, leaving space under the water tank 1 to install other items and improving space utilization.

[0064] In this embodiment, the media conveying system 100 has independent second interfaces 20 corresponding to the air inlet 21 and the water outlet 22, respectively. The air inlet 21 and the water outlet 22 are detachably sealed to their respective second interfaces 20 via sealing sections 3. A notch 11 is provided on the side wall of the water tank 1 for the first interface 200 and the second interface 20 to connect relative to each other. The second interface 20 is hidden within the notch 11. A mating structure is provided around the first interface 200, capable of at least partially fitting into the notch 11 and engaging with the inclined surface of the inner wall of the notch 11. In this embodiment, the sealing structure around the first interface 200 forms an inclined surface 201 that gradually slopes inward from the first interface 200. Correspondingly, the inner wall of the notch 11 can be a normally extending wall surface or a mating inclined surface matching the inclined surface 201. This structure can serve as a guide when the sealing sections are joined and sealed.

[0065] The positioning structure 300 is located between the air inlet 21 and the water outlet 22. The air inlet 21 and the water outlet 22 are symmetrically distributed on the positioning structure 300 to ensure reliable sealing of the second interface after connection and prevent water leakage. Through pre-positioning connection, synchronous and reliable sealing connection of the two second interfaces is achieved, which meets the user's requirement for long-term reliable sealing of the second interface under a pull force of less than 20N. At the same time, compared with the electrified second interface actuator, it achieves low cost and high reliability.

[0066] The positioning structure 300 in this embodiment includes a first part and a second part. The first part is disposed on the side of the cleaning tank 2, and the second part is disposed on the side of the media conveying system 100. The first part and the second part are detachably connected. This structure facilitates detachable connection. Specifically, the positioning structure 300 includes a latch 301 and a hook 302. The latch 301 constitutes the first part, and the hook 302 constitutes the second part. The latch 301 and the hook 302 are detachably plugged into each other. This structure facilitates plug-in connection.

[0067] The aforementioned latch 301 is a V-shaped structure with its opening facing outwards. Rollers 3011, arranged vertically at both ends of the V-shape, are provided for rolling engagement. The latch 302 has an arrowhead-shaped structure. During the docking process, the outer beveled surface 3021 of the latch 302 rolls between the two rollers 3011 and extends into the inner cavity 3012 of the V-shape. After docking, the inner end face 3022 of the latch 302 forms a rolling limit with the surfaces of the two rollers 3011 in the inner cavity 3012 of the V-shape. This structure facilitates pre-positioning during mouth-to-mouth docking and is also convenient for disassembly; separation can be achieved by overcoming the elasticity of the V-shaped latch 301, making operation easy. The force connecting the V-shaped latch 301 and the arrowhead-shaped latch 302 simultaneously applies pressure to the double-corrugated elastic end face of the sealing section 3, further increasing the sealing performance. During the medium transport process, the inner end face of the arrow of the locking hook 302 forms a rolling limit with the surfaces of the two rollers 3011 in the inner cavity of the V-shaped structure, allowing a certain amount of elastic expansion and contraction in the axial direction of the sealing section 3 to achieve adaptive sealing at the second interface.

[0068] To facilitate production and assembly, the side wall of the cleaning tank 2 is provided with a slot 23 that communicates with the first interface 200. A connector 4 is disposed in the slot 23, and a connector sleeve 5 is disposed on the outer side of the connector 4. A sealing section 3 is formed on the outer wall of the connector sleeve 5. The connector 4 is made of rigid plastic, while the connector sleeve 5 is made of a material that is easily elastically deformable to achieve an elastic seal. In this embodiment, the connector 4 and the connector sleeve 5 together constitute a connector E for mating the first interface and the second interface.

[0069] In this embodiment, the cleaning tank 2 and the media conveying system 100 are detachably connected by the insertion and mating of the sealing section 3 and the second interface 20. Since the sealing section 3 has a certain axial expansion and contraction force, when it is mated with the second interface 20, its head can be inserted into the second interface 20 by means of its axial elasticity. The edge of the second interface 20 just forms a snap-fit ​​limit with the recessed part on the outside of the sealing section 3. Such a connection structure is not only convenient for disassembly and assembly, but also has a certain axial expansion and contraction margin at the connection. During the medium flow process, the connection can expand and contract with the medium pressure, always maintaining good sealing performance and good sealing reliability.

[0070] Example 2:

[0071] The difference between this embodiment and Embodiment 1 is that: Figure 12 As shown in ~14, the sealing structure of the sealing section 3 is different from that of the second interface 20 on the medium conveying system 100.

[0072] Specifically, in this embodiment, when the first interface 200 and the second interface 20 are connected, the outer end face of the sealing section 3 is elastically pressed against the outer surface of the media conveying system 100 surrounding the second interface 20. In its natural state, the axial length of the sealing section 3 is greater than the distance between the first and second interfaces. Therefore, after the cleaning tank is moved into place, the sealing section 3 is elastically compressed between the first and second interfaces to form a seal. This structure is easy to assemble, and the connection point has low structural requirements, making it easy to manufacture.

[0073] The outer surface of the media conveying system 100 is provided with a boss 10a arranged around the second interface 20, and the outer end face of the sealing section 3 is elastically pressed against the boss 10a. The presence of this boss helps to further improve the compactness and reliability of the elastic seal between the sealing section and the sealing section.

[0074] A positioning structure is also provided between the cleaning tank 2 and the media conveying system 100 to maintain a sealed state between the outer end face of the sealing section 3 and the second interface 20 of the media conveying system 100. Since the seal between the outer end face of the sealing section 3 and the periphery of the second interface is achieved only by compression, there is a risk of water leakage when the water pressure impact is large. The above-mentioned positioning structure is provided to counteract the impact force on the sealing section 3 when the water pressure is too large, thereby maintaining the seal and preventing water leakage.

[0075] The outer end face of the sealing section 3 and the second interface 20 of the media conveying system 100 are dynamically sealed through a positioning structure. During fluid flow in the sealing section 3, the positioning structure constrains the displacement range within which the sealing section 3 can elastically expand and contract while maintaining a seal. This positioning structure allows a dynamic seal to form between the outer end face of the sealing section 3 and the second interface 20 of the media conveying system 100. This means the corrugated pipe can still expand and contract with water pressure changes, thus adaptively adapting to the water pressure and improving sealing performance. The constraint of the displacement range ensures that the sealing section can expand and contract within a certain range, further improving the reliability of the seal.

[0076] The positioning structure in this embodiment is the same as that in Embodiment 1, and will not be described again here.

[0077] Example 3:

[0078] In this embodiment, there are one or more positioning structures, which are located next to the second interface.

[0079] When multiple positioning structures are used, they are distributed on both sides of the second interface. This structure satisfies the need for more installation space while ensuring the reliability of the sealing effect.

[0080] Example 4:

[0081] like Figure 15As shown, in another preferred embodiment, the connector E' is arranged at the bottom of the cleaning container 1' and the cleaning tank 2', and is used to connect the cleaning container 1' and the cleaning tank 2' vertically. The connector E' can be set at the bottom of the cleaning container 1' to achieve vertical connection between the cleaning container 1' and the cleaning tank 2', which meets the needs of vertical transport of the medium. In this case, it is convenient for the cleaning tank 2' to be placed vertically in the cleaning container 1'.

[0082] 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.

[0083] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
