Description

Technical Field

[0001] This application belongs to the field of home appliance technology, and more specifically, relates to a cleaning component, a cleaning shelf, and a cleaning machine. Background Technology

[0002] In related technologies, cleaning machines typically use cleaning components to clean the items to be cleaned. However, existing cleaning components can only cover a limited area, making it difficult to achieve a complete cleaning of the items and resulting in incomplete cleaning. Utility Model Content

[0003] The purpose of this application is to provide a cleaning component, a cleaning shelf, and a cleaning machine, in order to solve the technical problem of limited cleaning range of cleaning components in related technologies.

[0004] To achieve the above objectives, according to one aspect of this application, a cleaning assembly is provided, comprising: an inlet pipe including a variable diameter section, a transition connecting platform, and a main body section connected in sequence; a rotating nozzle having multiple water outlet holes and an inlet pipe section penetrating into the interior of the rotating nozzle, the inlet pipe section being mounted on the transition connecting platform, the inner wall of the inlet pipe section being adjacent to the outer wall of the variable diameter section, or the outer wall of the inlet pipe section being adjacent to the inner wall of the variable diameter section, the inlet pipe section being rotatably mounted on the variable diameter section; and a limiting cover, at least part of which is integrally formed with the inlet pipe, the limiting cover being used to limit the end of the rotating nozzle away from the transition connecting platform.

[0005] Optionally, the diameter of the variable diameter section is smaller than the diameter of the main body section.

[0006] Optionally, a first contact protrusion is provided between the liquid inlet pipe section and the diameter changing section. The first contact protrusion is provided circumferentially along one of the liquid inlet pipe section and the diameter changing section, and is in line contact with the other.

[0007] Optionally, a second contact protrusion is provided between the liquid inlet pipe section and the transition connection platform. The second contact protrusion is provided circumferentially along one of the liquid inlet pipe section and the transition connection platform, and is in line contact with the other.

[0008] Optionally, the main body segment is a plastic structure capable of bending or torsion.

[0009] Optionally, the direction of the axis of the variable diameter section is the first direction; the extension direction of the water outlet is intersected with the first direction and intersected with the second direction, which is perpendicular to the first direction.

[0010] Optionally, the rotary nozzle also has a power hole communicating with the interior of the rotary nozzle. The power hole is spaced apart from the water outlet hole. The extension direction of the power hole is parallel to the second direction, and the axis of the power hole is spaced apart from the axis of the variable diameter section.

[0011] Optionally, the rotary nozzle includes a first rotary shell and a second rotary shell, wherein the second rotary shell and the first rotary shell are integrally formed to form an inner cavity.

[0012] Optionally, the shape of the projection surface of the rotating nozzle onto the preset projection surface is a rhombus, a four-pointed star, or a five-pointed star, and the preset projection surface is perpendicular to the axis of the variable diameter section.

[0013] Optionally, the limiting cover includes a first limiting shell and a second limiting shell, one of the first limiting shell and the second limiting shell is provided with a locking strip and / or a locking block, and the other is provided with a locking groove, the locking strip and / or the locking block being inserted into the locking groove; the second limiting shell is arranged around the main body segment; and / or, the second limiting shell and the main body segment are integrally formed; the second limiting shell is used to limit the end of the rotating nozzle away from the transition connecting platform.

[0014] According to another aspect of this application, a cleaning shelf is provided, including a frame, a water supply component, and multiple sets of the above-described cleaning components. The water supply component includes a water supply body and multiple fixed water supply pipes. The water supply body is disposed on the frame, and the multiple fixed water supply pipes are spaced apart around the axis of the water supply body. One of the fixed water supply pipes and the main body section is inserted into the other.

[0015] According to another aspect of this application, a cleaning machine is provided, including a mounting base and the aforementioned cleaning shelf, the mounting base having a mounting groove, and the cleaning shelf being disposed within the mounting groove.

[0016] The beneficial effects of the cleaning assembly provided in this application are as follows: When cleaning items, the cleaning assembly first places the items upside down onto the cleaning assembly so that the water outlet of the rotating nozzle extends into the interior of the item to be cleaned. Because the liquid inlet section of the rotating nozzle is rotatably positioned on the variable diameter section, the cleaning liquid can be sprayed 360° inside the item, allowing the cleaning liquid to reach every corner of the item (such as the bottom, inner wall, and top). Compared to a fixed spraying method, the cleaning assembly of this application can achieve multi-angle comprehensive cleaning, effectively reducing cleaning dead zones and improving cleaning results. Furthermore, when cleaning items, the cleaning assembly of this application can also directly spray cleaning liquid from the outside of the item to both the inside and outside of the component.

[0017] On the one hand, compared to traditional fixed spraying, the rotating nozzle generates centrifugal force, giving the sprayed cleaning liquid a stronger impact, thus more efficiently removing stains adhering to the inner walls of the items to be cleaned. Furthermore, because the cleaning liquid sprayed by the rotating nozzle in this application already possesses a certain water flow impact force, the spray pattern can be gentler, and the water flow can be more concentrated, eliminating the need for the high-impact water flow of traditional fixed spraying, thereby reducing noise. At the same time, this gentler spray pattern effectively reduces the risk of damage to the items to be cleaned due to excessive water flow impact, thus protecting the items being cleaned.

[0018] On the other hand, the liquid inlet section of the rotary nozzle is mounted on a transition connecting platform, with its inner wall adjacent to the outer wall of the reducing section, or vice versa. This connection method creates a plug-in, detachable connection between the reducing section and the liquid inlet section. This structural design not only allows the length of the liquid inlet pipe to be adjusted according to actual needs, thereby adjusting the depth to which the rotary nozzle penetrates into the item to be cleaned, but also enables precise adjustment of the spray position of the rotary nozzle to the areas requiring focused cleaning, based on the height and internal structure of the item, thus improving the flexibility of the cleaning components. Furthermore, different specifications of rotary nozzles can be added according to actual needs. This flexible selection of various parameters for the added rotary nozzles provides users with a personalized cleaning experience.

[0019] On the other hand, at least part of the limiting cover is integrally formed with the inlet pipe and is used to limit the end of the rotating nozzle away from the transition connection platform. This structural design not only effectively reduces the risk of the rotating nozzle shaking or deviating during rotation, ensuring its stable rotation around the diameter-changing section, allowing the cleaning fluid to be sprayed along the expected trajectory, thus guaranteeing the consistency and stability of the cleaning effect, but also effectively enhances the structural strength of the entire cleaning assembly, making it more robust and reliable during long-term use and reducing the risk of damage caused by external forces or frequent use.

[0041] In the description of this application, unless otherwise stated, " / " indicates that the objects before and after are in an "or" relationship. For example, A / B can mean A or B. "And / or" in this application is merely a description of the relationship between the related objects, indicating that there can be three relationships.

[0043] Reference Figures 1 to 8 To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides a cleaning assembly, which includes an inlet pipe 100, a rotating nozzle 200, and a limiting cover 300. The inlet pipe 100 includes a variable diameter section 110, a transition connecting platform 120, and a main body section 130 connected in sequence. The rotating nozzle 200 has multiple water outlet holes 210 and an inlet pipe section 220 penetrating into the interior of the rotating nozzle 200. The inlet pipe section 220 is mounted on the transition connecting platform 120, and its inner wall is adjacent to the outer wall of the variable diameter section 110, or its outer wall is adjacent to the inner wall of the variable diameter section 110. The inlet pipe section 220 is rotatably disposed on the variable diameter section 110. At least a portion of the limiting cover 300 is integrally formed with the inlet pipe 100, and the limiting cover 300 is used to limit the end of the rotating nozzle 200 away from the transition connecting platform 120.

[0044] In the embodiments of this application, the cleaning component is used in a baby bottle cleaning machine and is used to clean items 700 to be cleaned, such as baby bottles, nipples, breast pumps or other maternal and infant products; it is understood that the cleaning component can also be used in small household cleaning machines (such as fruit and vegetable cleaning machines, tableware cleaning machines, dishwashers), commercial cleaning machines (such as car washing machines) or baby bottle steam cleaners.

[0045] The diameter of the variable diameter section 110 can be greater than, less than, or equal to the diameter of the main body section 130. When the diameter of the variable diameter section 110 is greater than the diameter of the main body section 130, the transition connecting platform 120 is a platform-like structure that is recessed relative to the variable diameter section 110. When the diameter of the variable diameter section 110 is less than the diameter of the main body section 130, the transition connecting platform 120 is a platform-like structure that is convex relative to the variable diameter section 110. When the diameter of the variable diameter section 110 is equal to the diameter of the main body section 130, the transition connecting platform 120 is a platform-like structure that is coaxial with and has the same diameter as the variable diameter section 110. It can be understood that the transition connecting platform 120 can also be a stepped structure or a truncated cone structure.

[0046] The water outlet 210 is used to spray out cleaning liquid, which is water; it is understood that the cleaning liquid may also be a solution containing detergent, disinfectant liquid or liquid mixed with gas.

[0047] The inlet pipe section 220 extends from the outside of the rotating nozzle 200 into the inside of the rotating nozzle 200. One end of the inlet pipe section 220, near the transition connecting platform 120, is located outside the rotating nozzle 200 and is mounted on the transition connecting platform 120 located outside the rotating nozzle 200. The inner wall of the inlet pipe section 220 is adjacent to the outer wall of the reducing section 110, that is, the reducing section 110 is inserted into the inlet pipe section 220, and the inner wall of the inlet pipe section 220 and the outer wall of the reducing section 110 are in a close or near state, so that the inlet pipe section 220 is rotatably arranged around the axis of the reducing section 110 on the outer periphery of the reducing section 110. It is understandable that the outer wall of the liquid inlet pipe section 220 can also be adjacent to the inner wall of the reducing section 110, that is, the liquid inlet pipe section 220 is inserted into the reducing section 110, and the outer wall of the liquid inlet pipe section 220 is in close contact with or near the inner wall of the reducing section 110, so that the liquid inlet pipe section 220 is rotatably disposed around the axis of the reducing section 110 on the inner circumference of the reducing section 110. In addition, the liquid inlet pipe section 220 is part of the structure of the rotary nozzle 200. Furthermore, in order to enhance the rotational stability of the rotary nozzle 200, the end of the liquid inlet pipe section 220 away from the transition connecting platform 120 extends into the interior of the rotary nozzle 200 to increase the contact area with the reducing section 110.

[0048] A first limiting protrusion 310 is provided on the inner wall surface of the limiting cover 300 near the end of the rotating nozzle 200 away from the transition connecting platform 120, and a second limiting protrusion 230 is provided on the end of the rotating nozzle 200 away from the transition connecting platform 120. The limiting cover 300 limits the rotating nozzle 200 by contacting the first limiting protrusion 310 and the second limiting protrusion 230, that is, it prevents the rotating nozzle 200 from deflecting and / or shifting. The deflection of the rotating nozzle 200 refers to the unexpected angular tilting, swinging or twisting of the rotating nozzle 200 around its normal rotation axis when it is rotating normally or stationary. The shift of the rotating nozzle 200 refers to the unexpected positional movement of the rotating nozzle 200 along the axial or radial direction when it is rotating normally or stationary. It is understandable that the inner wall surface of the limiting cover 300 near the end of the rotating nozzle 200 away from the transition connecting platform 120 and the end of the rotating nozzle 200 away from the transition platform may also be provided with a matching sleeve and end cap or guide bearing and shoulder retaining ring.

[0049] When cleaning the item 700 to be cleaned using the cleaning assembly of this application, the item 700 is first placed upside down on the cleaning assembly so that the water outlet 210 of the rotating nozzle 200 extends into the interior of the item to be cleaned. Because the liquid inlet section 220 of the rotating nozzle 200 is rotatably mounted on the reducing section 110, the cleaning liquid can be sprayed 360° inside the item 700, allowing the cleaning liquid to reach every corner inside the item 700 (such as the bottom, inner wall, and top of the item 700). Compared to a fixed spraying method, the cleaning assembly of this application can achieve comprehensive cleaning from multiple angles, effectively reducing cleaning dead zones and improving cleaning results. Furthermore, when cleaning the item 700, the cleaning assembly of this application can also directly spray the cleaning liquid from the outside of the item 700 to both the interior and exterior of the item.

[0050] On the one hand, compared to traditional fixed spraying, the rotating nozzle 200 generates centrifugal force, giving the sprayed cleaning liquid a stronger impact force, thus more efficiently removing stains adhering to the inner wall of the item 700 to be cleaned. Furthermore, since the cleaning liquid sprayed by the rotating nozzle 200 already possesses a certain water flow impact force, the spray pattern can be gentler, and the water flow can be more concentrated, eliminating the need for the high-impact water flow of traditional fixed spraying, thereby reducing noise. Simultaneously, this gentler spray pattern effectively reduces the risk of damage to the item 700 to be cleaned due to excessive water flow impact force, thus protecting the item 700.

[0051] On the other hand, the liquid inlet pipe section 220 of the rotary nozzle 200 is mounted on the transition connecting platform 120, and the inner wall of the liquid inlet pipe section 220 is adjacent to the outer wall of the variable diameter section 110, or the outer wall of the liquid inlet pipe section 220 is adjacent to the inner wall of the variable diameter section 110. This connection method allows the variable diameter section 110 and the liquid inlet pipe section 220 to form a plug-in detachable connection structure. This structural design not only allows the length of the liquid inlet pipe 100 to be adjusted according to actual needs, thereby adjusting the depth of the rotary nozzle 200 into the item 700 to be cleaned, but also allows the spray position of the rotary nozzle 200 to be precisely adjusted to the areas that need to be cleaned according to the height and internal structure of the item 700, improving the flexibility of the cleaning components. At the same time, different specifications of rotary nozzles 200 can be added according to actual needs. This feature of flexibly selecting various parameters of the rotary nozzle 200 provides users with a personalized cleaning experience.

[0052] On the other hand, at least a portion of the limiting cover 300 is integrally formed with the inlet pipe 100 and is used to limit the end of the rotating nozzle 200 away from the transition connecting platform 120. This structural design not only effectively reduces the risk of the rotating nozzle 200 shaking or deviating during rotation, ensuring its stable rotation around the diameter-changing section 110, allowing the cleaning fluid to be sprayed along the expected trajectory, thus guaranteeing the consistency and stability of the cleaning effect, but also effectively enhances the structural strength of the entire cleaning assembly, making it more robust and reliable during long-term use and reducing the risk of damage caused by external forces or frequent use.

[0053] Reference Figure 6 In one embodiment, the diameter of the variable diameter section 110 is smaller than the diameter of the main body section 130. In this embodiment, the transition connecting platform 120 is coaxially arranged with the variable diameter section 110.

[0054] The above structural design not only increases the flow rate of the cleaning liquid flowing from the main section 130 to the variable diameter section 110, thereby increasing the fluid pressure; but also makes the high-pressure, high-speed cleaning liquid more impactful when it is sprayed out of the water outlet 210 after entering the rotary nozzle 200 through the variable diameter section 110, which can more effectively remove stains from the surface of the item 700 to be cleaned, thus helping to improve cleaning efficiency and cleanliness.

[0055] Meanwhile, the smaller diameter of the variable diameter section 110 allows it to nest with the liquid inlet pipe section 220 of the rotary nozzle 200. This design enables the liquid inlet pipe section 220 to rotate more precisely around the variable diameter section 110, reducing radial sway and ensuring the rotational stability of the rotary nozzle 200. This, in turn, ensures that the spray trajectory of the water outlet 210 is controllable and the cleaning range is stable.

[0056] Reference Figure 6 as well as Figure 9 In one embodiment, a first contact protrusion 221 is provided between the liquid inlet pipe section 220 and the variable diameter section 110. The first contact protrusion 221 is provided circumferentially along one of the liquid inlet pipe section 220 and the variable diameter section 110, and is in line contact with the other.

[0057] In this embodiment, the first contact protrusion 221 is a contact ring, and it is disposed around the inner wall surface of the liquid inlet pipe section 220 in the circumferential direction. It can be understood that the first contact protrusion 221 may also include a plurality of contact protrusions spaced apart in the circumferential direction of the liquid inlet pipe section 220, or the first contact protrusion 221 may also include a plurality of contact protrusions and contact strips spaced apart in the circumferential direction of the liquid inlet pipe section 220; in addition, the first contact protrusion 221 may also be disposed on the outer circumferential surface of the variable diameter section 110.

[0058] Compared to surface contact, the line contact between the inlet pipe section 220 and the variable diameter section 110, achieved through the first contact protrusion 221, not only reduces the contact area, thereby lowering rotational friction resistance and improving rotational flexibility and durability, thus extending their service life, but also precisely constrains the relative positions of the inlet pipe section 220 and the variable diameter section 110, thereby improving their concentricity and ensuring the stability of the injection trajectory.

[0059] In addition, the line contact provided by the first contact protrusion 221 can also form a sealing barrier between the liquid inlet section 220 and the variable diameter section 110, which can to a certain extent prevent the cleaning liquid from leaking outward from the gap between the liquid inlet section 220 and the variable diameter section 110, ensuring that more cleaning liquid in the rotary nozzle 200 is sprayed out from the water outlet 210, thereby improving the utilization rate of the cleaning liquid.

[0060] In addition, the line contact design only needs to ensure the manufacturing accuracy of the first contact protrusion 221, without the need for high-precision machining of the entire surface of the liquid inlet section 220 and the variable diameter section 110, which reduces the manufacturing difficulty and cost.

[0061] Reference Figure 6 as well as Figure 9 In one embodiment, a second contact protrusion 222 is provided between the liquid inlet pipe section 220 and the transition connecting platform 120. The second contact protrusion 222 is arranged circumferentially along one of the liquid inlet pipe section 220 and the transition connecting platform 120, and is in line contact with the other.

[0062] In this embodiment, the second contact protrusion 222 is a contact ring, and is disposed around the circumference of the liquid inlet pipe section 220 on the surface of the liquid inlet pipe section 220 near the transition connecting platform 120. It is understood that the second contact protrusion 222 may also include a plurality of contact protrusions spaced apart circumferentially along the liquid inlet pipe section 220, or the second contact protrusion 222 may also include a plurality of contact protrusions and contact strips spaced apart circumferentially along the liquid inlet pipe section 220; in addition, the second contact protrusion 222 may also be disposed on the surface of the transition connecting platform 120 near the liquid inlet pipe section 220.

[0063] Compared to surface contact, the second contact protrusion 222 enables line contact between the liquid inlet pipe section 220 and the transition connecting platform 120. This not only reduces the contact area between the two, thereby lowering rotational friction resistance and improving rotational flexibility and durability, but also extends their service life. Simultaneously, it establishes a stable support structure between the liquid inlet pipe section 220 and the transition connecting platform 120, thereby improving the axial support stiffness and stability of the rotating nozzle 200 and ensuring the stability of the spray trajectory.

[0064] In addition, the line contact provided by the second contact protrusion 222 can also form a sealing barrier between the liquid inlet section 220 and the transition connecting platform 120. When used in conjunction with the first contact protrusion 221, it can further prevent the cleaning liquid from leaking outward from the gap between the liquid inlet section 220 and the variable diameter section 110, ensuring that more cleaning liquid in the rotary nozzle 200 is sprayed out from the water outlet 210, thereby improving the utilization rate of the cleaning liquid.

[0065] In addition, the line contact design only needs to ensure the manufacturing accuracy of the second contact protrusion 222, without the need for high-precision machining of the entire surface of the liquid inlet pipe section 220 and the transition connection platform 120, which reduces the manufacturing difficulty and cost.

[0066] Reference Figures 3 to 5 as well as Figure 8 In one embodiment, the main body segment 130 is a plastic structure capable of bending or torsion. In this embodiment, the main body segment 130 is one of a flexible hose, a bellows, a universal joint type flexible tube, or a helical spring tube.

[0067] The main body section 130 can be bent or twisted. This structural design allows the rotating nozzle 200 to adapt to different shapes of items 700 to be cleaned (such as conical bottles, square bottles, or bottles with special curvature). By bending the main body section 130, the rotating nozzle 200 can not only enter the interior of the item 700 to be cleaned more smoothly, but also better conform to the inner wall of the item 700 to be cleaned, ensuring that every part of the item 700 to be cleaned is accurately rinsed by the water flow, thereby achieving all-round cleaning. Compared with the traditional fixed spraying method, the combined use of the main body section 130 and the rotating nozzle 200 broadens the applicability of the cleaning components.

[0068] Reference Figure 5 as well as Figures 7 to 9 In one embodiment, the axis of the variable diameter section 110 is in the first direction; the extension direction of the water outlet 210 intersects the first direction and intersects the second direction, which is perpendicular to the first direction.

[0069] In this embodiment, the angle between the extension direction of the water outlet 210 and the first direction is an acute angle, and the angle between the extension direction and the second direction is also an acute angle.

[0070] On the one hand, the extension direction of the water outlet 210 intersects with both the first and second directions, meaning that the water spray direction is not along a single dimension, but can form a spray trajectory with multiple angles. When the rotating nozzle 200 rotates around the axis of the variable diameter section 110, this multi-angle spraying method not only effectively improves the comprehensiveness of the cleaning coverage and reduces cleaning dead corners, but also forms oblique or multi-angle flushing on the same position of the item 700 to be cleaned, effectively improving the cleaning effect on stubborn stains.

[0071] On the other hand, the extension direction of the water outlet 210 (i.e., the water spray direction) intersects with the first direction, meaning that when the water is sprayed, a reaction force perpendicular to the axis of the variable diameter section 110 is generated. This force can form a rotational torque around the first direction, driving the rotary nozzle 200 to rotate automatically. This self-driving design not only simplifies the structure of the cleaning components, but also allows the water spray trajectory to form a dynamic circular or spiral coverage range, avoiding local over-rinsing or under-rinsing caused by fixed spraying, and achieving uniform and comprehensive cleaning.

[0072] Reference Figure 5 , Figure 7 as well as Figure 8 In one embodiment, the rotary nozzle 200 further has a power hole 240 communicating with the interior of the rotary nozzle 200. The power hole 240 is spaced apart from the water outlet 210. The extension direction of the power hole 240 is parallel to the second direction, and the axis of the power hole 240 is spaced apart from the axis of the variable diameter section 110.

[0073] On one hand, the extension direction of the power orifice 240 is parallel to the second direction, meaning that the direction of the water flow it ejects is perpendicular to the first direction (the direction of the axis of the variable diameter section 110). According to the principle of reaction force, the water flow generates a reaction force along the second direction when it is ejected. This force can directly form a rotational torque about the first direction, providing stable power for the rotation of the rotating nozzle 200. Compared to relying solely on the oblique water spray drive of the outlet orifice 210, the power orifice 240 can specifically enhance the driving force, ensuring that the rotating nozzle 200 can stably start and rotate even under low water pressure or high load.

[0074] On the other hand, the water outlet 210 is responsible for achieving multi-angle spraying to ensure comprehensive cleaning; while the power outlet 240 focuses on providing rotational power, and its water spray parallel to the second direction can simultaneously form an auxiliary flushing on the area perpendicular to the axis of the variable diameter section 110, complementing the spray trajectory of the water outlet 210 and enhancing the cleaning effect.

[0075] In other embodiments, the rotary nozzle 200 may also have a spray hole, the extension direction of which is perpendicular to the first direction, so as to achieve vertical spraying of the cleaning liquid.

[0076] Reference Figures 3 to 5 as well as Figure 9 In one embodiment, the rotary nozzle 200 includes a first rotary shell 250 and a second rotary shell 260, wherein the second rotary shell 260 and the first rotary shell 250 are integrally formed to form an inner cavity.

[0077] In this embodiment, the liquid inlet pipe section 220 is disposed on the second rotating shell 260 and is integrally formed with the second rotating shell 260; the first rotating shell 250 is located on the side of the second rotating shell 260 away from the transition connecting platform 120. The internal space of the first rotating shell 250 is in communication with the internal space of the second rotating shell 260 to form the inner cavity of the rotating nozzle 200. At the same time, in order to ensure the spray pressure of the cleaning liquid sprayed through the water outlet 210, the surface of the first rotating shell 250 near the second rotating shell 260 and the surface of the second rotating shell 260 near the first rotating shell 250 are kept in close contact. It is understood that the second rotating shell 260 and the first rotating shell 250 can also be connected by ultrasonic welding, fastening, or screw connection.

[0078] The water outlet 210 and the power outlet 240 can both be located on one of the first rotating shell 250 and the second rotating shell 260, or they can be located on the first rotating shell 250 and the second rotating shell 260 respectively, depending on actual needs, and are not limited here. Furthermore, for ease of manufacturing, the second rotating shell 260 has the same basic structure as the first rotating shell 250. By disassembling the rotating nozzle 200 into the first rotating shell 250 and the second rotating shell 260, the required structures can be machined on the two rotating shells respectively, ensuring that the different structures do not interfere with each other.

[0079] Reference Figures 7 to 9 In one embodiment, there are multiple water outlet holes 210, which are spaced apart, and the extending directions of any two water outlet holes 210 are parallel.

[0080] In this embodiment, a plurality of water outlet holes 210 are arranged at intervals along the circumference of the rotating nozzle 200. It can be understood that the plurality of water outlet holes 210 may also be arranged at intervals along the axial, radial or other directions of the rotating nozzle 200.

[0081] The parallel extension directions of all water outlets 210 not only mean that their spray direction is consistent, but also that when the rotating nozzle 200 rotates around the axis of the variable diameter section 110, the multiple spaced and parallel water outlets 210 will form a concentric annular or spiral spray trajectory centered on the axis of the variable diameter section 110. This ensures that the scouring angle and force on all parts of the item 700 to be cleaned are completely consistent, avoiding uneven cleaning in some areas due to differences in direction.

[0082] Meanwhile, the multiple parallel water outlets 210, in conjunction with the rotation of the rotating nozzle 200, expand the coverage area of ​​the three-dimensional space and reduce cleaning dead zones. Furthermore, the parallel nature of all the water outlets 210 also reduces manufacturing difficulty.

[0083] Reference Figures 7 to 9 In one embodiment, there are multiple water outlet holes 210, which are spaced apart, and at least two water outlet holes 210 are arranged in intersecting directions.

[0084] In this embodiment, any two water outlet holes 210 are arranged with their extension directions intersecting. It is understood that only two, three, or a number equal to the total number of water outlet holes 210 minus two, may have their extension directions intersecting, while the remaining water outlet holes 210 have their extension directions parallel to each other and parallel to the extension direction of one of the intersecting water outlet holes 210. Furthermore, multiple water outlet holes 210 are spaced apart circumferentially along the rotating nozzle 200. It is understood that the multiple water outlet holes 210 may also be spaced apart axially, radially, or in other directions along the rotating nozzle 200.

[0085] The intersecting water outlets 210 can form intersecting spray trajectories in space. When the rotating nozzle 200 rotates, these intersecting water streams can cover different dimensional areas inside the item 700 to be cleaned, thus expanding the cleaning range of the cleaning assembly.

[0086] Meanwhile, the intersecting water outlets 210 can create water flow impacts at different angles on the same key area of ​​the item 700 to be cleaned, strengthening the multiple rinsing of the same location and thus improving cleaning efficiency.

[0087] In addition, in one specific embodiment, the first rotating shell 250 is provided with four water outlet holes 210 at intervals, and the extension directions of the four water outlet holes 210 intersect each other; the second rotating shell 260 is provided with two power holes 240 at intervals. Figure 8 The dotted line in the figure refers to the spray path of the cleaning liquid that is sprayed outward through the water outlet 210 and the power outlet 240.

[0088] Reference Figures 3 to 5 as well as Figure 9 In one embodiment, the shape of the projection surface of the rotating nozzle 200 onto the preset projection surface is rhomboid, and the preset projection surface is perpendicular to the axis of the variable diameter section 110.

[0089] In this embodiment, the preset projection surface is parallel to the end face of the variable diameter section 110, and the overall shape of the rotating nozzle 200 is similar to that of an ellipsoid. It is understood that the shape of the projection surface of the rotating nozzle 200 onto the preset projection surface can also be a triangle, a regular square, a hexagon, or a circle, etc., without much restriction, depending on actual needs.

[0090] The rhomboid projection shape allows the distance and angle between the water outlets 210 in different positions and the surface of the item 700 to be cleaned to change dynamically during the rotation of the rotating nozzle 200. Compared to the circular projection shape of the rotating nozzle 200, the rhomboid structure creates differentiated spray paths in the major and minor axis directions, allowing the cleaning liquid to cover a more complex three-dimensional space and reducing cleaning blind spots.

[0091] At the same time, the four vertices of the rhombus form a larger circular trajectory when rotating, which makes the spray range of the edge area wider and improves the cleaning power of the edge area.

[0092] Furthermore, for the same projected area, the perimeter of a rhombus structure is smaller than that of a rectangle or circle, which helps to reduce the amount of material used and achieve a lightweight design. This not only helps to reduce manufacturing costs, but also reduces the inertial torque during rotation, making the rotary nozzle 200 more flexible in starting and stopping.

[0093] Reference Figures 3 to 5 as well as Figure 9 In one embodiment, the shape of the projection surface of the rotating nozzle 200 onto the preset projection surface is a quadrilateral star or a pentagonal star, and the preset projection surface is perpendicular to the axis of the variable diameter section 110. It is understood that the shape of the projection surface of the rotating nozzle 200 onto the preset projection surface can also be a triangular star, a hexagonal star, or other polygonal star shapes.

[0094] The four-pointed or five-pointed star projection shape not only allows the cleaning liquid sprayed by the rotating nozzle 200 to cover a more complex three-dimensional space and reduce cleaning blind spots, but also helps to improve the cleaning effect in edge areas.

[0095] Furthermore, the unique geometric shapes of four-pointed or five-pointed stars not only help enhance product recognizability through appearance design but also facilitate user identification of rotating nozzles 200 with different shapes. (See reference) Figures 3 to 5 In one embodiment, the limiting cover 300 has a communicating limiting space 320 and a liquid outlet 330. The rotating nozzle 200 is rotatably disposed within the limiting space 320. A limiting gap 340 is provided between the inner wall of the limiting space 320 and the rotating nozzle 200 to limit the deflection and / or offset of the rotating nozzle 200.

[0096] In this embodiment, the limiting space 320 is the internal space of the limiting cover 300 and is a completely enclosed annular structure. The liquid outlet 330 is disposed on the outer surface of the limiting cover 300 and is a through hole extending into the limiting space 320. To minimize the obstruction effect of the limiting cover 300 on the cleaning liquid sprayed outward from the water outlet 210, multiple liquid outlets 330 are provided, spaced apart circumferentially along the limiting cover 300. The limiting gap 340 is smaller than any dimension of the rotating nozzle 200 in the first and second directions to limit the deflection and offset of the rotating nozzle 200 within the limiting space 320. Specifically, the maximum outer diameter of the rotating nozzle 200 is slightly smaller than the minimum inner diameter of the limiting space 320.

[0097] When the cleaning component sprays cleaning liquid outward, the cleaning liquid is first delivered to the rotary nozzle 200 through the liquid inlet pipe 100, and then sprayed outward through the water outlet 210. During this process, the sprayed cleaning liquid will be sprayed outward through the limiting space 320 and the liquid outlet 330 to the outside of the cleaning component.

[0098] The limiting space 320 not only constrains the shaking of the rotating nozzle 200 through the limiting gap 340, ensuring its smooth rotation and spraying operation, but also reduces the risk of interference between the item to be cleaned 700 and the rotating nozzle 200 through physical isolation, avoiding direct contact between the two as much as possible, and further provides a stable environment for the rotating spraying of the rotating nozzle 200, ensuring reliable operation.

[0099] Reference Figures 3 to 5 , Figure 8 as well as Figure 10 In one embodiment, the limiting cover 300 includes a first limiting shell 350 and a second limiting shell 360. One of the second limiting shell 360 and the second limiting shell 360 is provided with a locking strip and / or a locking block 361, and the other is provided with a locking groove 351. The locking strip and / or the locking block 361 is inserted into the locking groove 351.

[0100] In this embodiment, the first limiting shell 350 is correspondingly disposed with the first rotating shell 250, and the second limiting shell 360 is correspondingly disposed with the second rotating shell 260. The second limiting shell 360 is provided with a plurality of locking blocks 361 spaced apart along its circumference, and the first limiting shell 350 is provided with the same number of slots 351 as the locking blocks 361. It can be understood that the second limiting shell 360 may also be provided with annular locking strips arranged along its circumference, and the first limiting shell 350 may be provided with annular slots 351; the second limiting shell 360 may also be provided with locking blocks 361 and arc-shaped locking strips arranged along its circumference, and the first limiting shell 350 may be provided with corresponding slots 351; furthermore, locking blocks 361 and / or locking strips may also be disposed on the first limiting shell 350, and slots 351 may be disposed on the second limiting shell 360. In addition, the main structure of the second limiting shell 360 is the same as that of the first limiting shell 350.

[0101] With the cooperation of the locking strip and / or locking block 361 with the locking slot 351, the first limiting shell 350 and the second limiting shell 360 can be quickly aligned and fixed without the need for additional fasteners or complicated tools, thus shortening the assembly and disassembly time of the first limiting shell 350 and the second limiting shell 360.

[0102] Meanwhile, when the rotary nozzle 200 needs maintenance, the limiting cover 300 can be easily disassembled by applying appropriate external force to separate the locking structure without damaging any parts, thus improving the convenience of maintaining and replacing the rotary nozzle 200. In addition, dividing the limiting cover 300 into two independent housings simplifies the mold structure and reduces the difficulty and cost of mold manufacturing.

[0103] Reference Figures 3 to 5 In one embodiment, the second limiting shell 360 is disposed around the main body segment 130. In this embodiment, the main structure of the second limiting shell 360 surrounds or partially surrounds the main body segment 130 circumferentially.

[0104] The second limiting shell 360 surrounding the main body section 130 not only prevents the item to be cleaned 700 from directly contacting the main body section 130, forming physical protection and extending the service life of the main body section 130; it also helps to integrate the cleaning components, thereby reducing the overall size of the cleaning components.

[0105] Reference Figures 3 to 5 In one embodiment, the second limiting shell 360 and the main body segment 130 are integrally formed. It is understood that the second limiting shell 360 and the main body segment 130 can also be connected by ultrasonic welding, fastening, screw connection or adhesive bonding.

[0106] The second limiting shell 360 and the main body segment 130 are integrally molded. This structural design not only improves the connection strength between the second limiting shell 360 and the main body segment 130, thereby enhancing the stability of the limiting cover 300 on the main body segment 130, but also indirectly optimizes the limiting effect of the limiting cover 300. At the same time, it simplifies the processing and assembly procedures.

[0107] Reference Figures 3 to 5 In one embodiment, the size of the limiting cover 300 in the first direction is a first size, and the size of the limiting cover 300 in the second direction is a second size, which is different from the first size.

[0108] In this embodiment, the first dimension is smaller than the second dimension. It is understood that the second dimension can also be smaller than the first dimension. The second dimension is different from the first dimension. Combined with the design that the main body segment 130 can be bent or twisted, when the cleaning component is inserted into the small-diameter item 700 to be cleaned, the bending of the main body segment 130 can drive the rotating nozzle 200 and the limiting cover 300 to deflect, thereby allowing the limiting cover 300 in the cleaning component to smoothly enter the interior at the smaller value between the first dimension and the second dimension. This structural design improves the convenience of the cleaning component entering or exiting the item 700 to be cleaned.

[0109] Reference Figures 3 to 5 In one embodiment, the shape of the projection surface of the limiting cover 300 onto the preset projection surface is polygonal or circular, and the preset projection surface is perpendicular to the axis of the variable diameter section 110.

[0110] In this embodiment, the preset projection surface is parallel to the end face of the variable diameter section 110, and the shape of the projection surface of the limiting cover 300 onto the projection surface is circular, and the overall shape of the limiting cover 300 is similar to that of an ellipsoid; it can be understood that the shape of the projection surface of the limiting cover 300 onto the projection surface can also be a triangle, a quadrilateral, a hexagon or other polygons.

[0111] The core function of the limiting cover 300 is to constrain the swaying of the rotating nozzle 200. Its projected shape is designed to match the projected shape of the rotating nozzle 200. This fit allows the limiting gap 340 to be more evenly distributed circumferentially, which can more accurately limit the offset or deflection of the rotating nozzle 200, avoid local collisions caused by uneven limiting gap 340, and ensure that the rotating nozzle 200 always rotates stably around the variable diameter section 110.

[0112] Reference Figures 1 to 15According to another aspect of this application, an embodiment of this application also provides a cleaning shelf, which includes a frame 400, a water supply component 500, and multiple sets of the above-mentioned cleaning components. The water supply component 500 includes a water supply body 510 and multiple fixed water supply pipes 520. The water supply body 510 is disposed on the frame 400, and the multiple fixed water supply pipes 520 are spaced apart around the axis of the water supply body 510. One of the fixed water supply pipes 520 and the main body segment 130 is inserted into the other.

[0113] In this embodiment, the frame 400 is used not only to support the water supply component 500, but also to support the items 700 to be cleaned. The water supply body 510 is a water supply base, which is fixedly installed on the frame 400. Multiple fixed water supply pipes 520 are evenly spaced around the axis of the water supply body 510, and the axis of the fixed water supply pipes 520 is parallel to the axis of the water supply body 510. It can be understood that the multiple fixed water supply pipes 520 can also be distributed in a straight line or a curve. The cleaning component may also consist of only one set.

[0114] Furthermore, the number of fixed water supply pipes 520 is the same as the number of cleaning components. It is understood that the number of fixed water supply pipes 520 may also differ from the number of cleaning components, depending on actual needs, and is not limited here. The main body section 130 is interference-fitted into the fixed water supply pipe 520. It is understood that the main body section 130 may also be loosely inserted into the fixed water supply pipe 520, and the fixed water supply pipe 520 may also be inserted into the main body section 130.

[0115] On the one hand, multiple cleaning components can be positioned at different locations and heights according to the structural layout of the item 700 to be cleaned. After being uniformly supplied with water by the water supply unit 500, the rotating nozzles 200 of each cleaning component can spray water from multiple angles. Each rotating nozzle 200 is responsible for cleaning a different area, ensuring that the item 700 to be cleaned is thoroughly cleaned. Compared with a single cleaning component, this multi-directional collaborative cleaning can cover the inner and outer surfaces, corners, and crevices of the item 700 to be cleaned, avoiding local omissions and improving cleaning efficiency and coverage. At the same time, centralized water supply through the water supply unit 500 not only reduces pipeline complexity but also facilitates unified maintenance and reduces repair costs.

[0116] On the other hand, the design of inserting one of the fixed water supply pipe 520 and the main body section 130 into the other not only facilitates quick assembly and disassembly of the fixed water supply pipe 520 and the main body section 130, but also allows for direct separation and individual replacement of damaged parts in case of malfunction of the cleaning components or the fixed water supply pipe 520, reducing maintenance difficulty and cost. Furthermore, it facilitates the replacement of different specifications of the main body section 130 and the rotating nozzle 200 according to different usage needs, broadening the applicability of the cleaning shelf and enhancing its flexibility.

[0117] Furthermore, the rotation directions of two adjacent rotary nozzles 200 can be the same or opposite. Specifically, when the two rotary nozzles 200 rotate in the same direction, the scouring force of the water flow is enhanced, quickly removing stubborn stains over large areas. When the two rotary nozzles 200 rotate in opposite directions, the water flow can form a complex vortex inside the item 700 to be cleaned, allowing the water to penetrate into every tiny corner, thus achieving comprehensive and thorough cleaning.

[0118] Reference Figures 1 to 15 According to another aspect of this application, embodiments of this application provide a cleaning machine, which includes a mounting base 600 and the aforementioned cleaning shelf. The mounting base 600 has a mounting groove 610, and the cleaning shelf is disposed within the mounting groove 610.

[0119] In this embodiment, the cleaning machine is a baby bottle cleaner. It is understood that the cleaning machine can also be a small household cleaning machine (such as a fruit and vegetable cleaner, dishwashing machine, or dishwasher), a commercial cleaning machine (such as a car wash machine), or a baby bottle steam cleaner. The cleaning shelf is installed within the mounting groove 610.

[0120] The mounting base 600 serves as a load-bearing foundation, providing rigid support for the cleaning shelf and effectively reducing the risk of the cleaning shelf shaking or tilting due to the placement of items 700 to be cleaned or impact from the cleaning liquid. Meanwhile, the mounting groove 610 not only accommodates the cleaning shelf, thus optimizing the layout of the cleaning machine and reducing its size, but also provides a protective enclosure for the cleaning shelf.

[0121] Reference Figure 11 In one embodiment, the cleaning machine further includes a protective cover 620, which is pivotally connected to the mounting base 600 for covering the cleaning rack.

[0122] In summary, implementing the cleaning assembly, cleaning shelf, and cleaning machine provided in this embodiment has at least the following beneficial technical effects: When cleaning the item 700 to be cleaned, the cleaning assembly of this application first places the item 700 upside down onto the cleaning assembly so that the water outlet 210 of the rotating nozzle 200 extends into the interior of the part to be cleaned; since the liquid inlet section 220 of the rotating nozzle 200 is rotatably arranged on the variable diameter section 110, the cleaning liquid can be sprayed in a 360° rotation inside the item 700 to be cleaned, thereby allowing the cleaning liquid to reach every corner inside the item 700 to be cleaned (such as the bottom, inner wall, and top of the item 700 to be cleaned); compared with the fixed spraying method, the cleaning assembly of this application can achieve multi-angle comprehensive cleaning, effectively reducing cleaning dead corners and effectively improving the cleaning effect. In addition, when cleaning the item 700 to be cleaned, the cleaning assembly of this application can also directly spray the cleaning liquid from the outside of the item 700 to the inside and outside of the part to be cleaned.

[0123] On the one hand, compared to traditional fixed spraying, the rotating nozzle 200 generates centrifugal force, giving the sprayed cleaning liquid a stronger impact force, thus more efficiently removing stains adhering to the inner wall of the item 700 to be cleaned. Furthermore, since the cleaning liquid sprayed by the rotating nozzle 200 already possesses a certain water flow impact force, the spray pattern can be gentler, and the water flow can be more concentrated, eliminating the need for the high-impact water flow of traditional fixed spraying, thereby reducing noise. Simultaneously, this gentler spray pattern effectively reduces the risk of damage to the item 700 to be cleaned due to excessive water flow impact force, thus protecting the item 700.

[0124] On the other hand, the liquid inlet pipe section 220 of the rotary nozzle 200 is mounted on the transition connecting platform 120, and the inner wall of the liquid inlet pipe section 220 is adjacent to the outer wall of the variable diameter section 110, or the outer wall of the liquid inlet pipe section 220 is adjacent to the inner wall of the variable diameter section 110. This connection method allows the variable diameter section 110 and the liquid inlet pipe section 220 to form a plug-in detachable connection structure. This structural design not only allows the length of the liquid inlet pipe 100 to be adjusted according to actual needs, thereby adjusting the depth of the rotary nozzle 200 into the item 700 to be cleaned, but also allows the spray position of the rotary nozzle 200 to be precisely adjusted to the areas that need to be cleaned according to the height and internal structure of the item 700, improving the flexibility of the cleaning components. At the same time, different specifications of rotary nozzles 200 can be added according to actual needs. This feature of flexibly selecting various parameters of the rotary nozzle 200 provides users with a personalized cleaning experience.

[0125] On the other hand, at least a portion of the limiting cover 300 is integrally formed with the inlet pipe 100 and is used to limit the end of the rotating nozzle 200 away from the transition connecting platform 120. This structural design not only effectively reduces the risk of the rotating nozzle 200 shaking or deviating during rotation, ensuring its stable rotation around the diameter-changing section 110, allowing the cleaning fluid to be sprayed along the expected trajectory, thus guaranteeing the consistency and stability of the cleaning effect, but also effectively enhances the structural strength of the entire cleaning assembly, making it more robust and reliable during long-term use and reducing the risk of damage caused by external forces or frequent use.

[0126] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
