[0002] This application claims priority to Chinese patent application No. 202520445127.8, filed March 14, 2025, and Chinese patent application No. 202521838732.8, filed August 27, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of cleaning machine technology, specifically to a water spraying device, rinsing assembly, rinsing rack, and cleaning equipment for a cleaning machine. Background Technology

[0004] The water spray cleaning device in a cleaning machine usually includes a support, a nozzle, and a water inlet pipe. The water inlet pipe is used to introduce water into the nozzle, the nozzle is used to spray water for easy cleaning, and the support is used to install the nozzle. Nozzles include rotatable and non-rotatable nozzles. For rotatable nozzles, a rotating mechanism is usually required to drive the nozzle's rotation. To ensure the nozzle's rotation and stability during rotation, the installation structure of the nozzle is generally quite complex, making it difficult to disassemble. Especially when a nozzle malfunctions, the entire cleaning device needs to be removed from the cleaning machine, which is quite troublesome. Summary of the Invention

[0005] This application provides a water spraying device, rinsing assembly, rinsing rack, and cleaning equipment for a cleaning machine, aiming to solve the problem that the installation structure of the rotating nozzle in the prior art is relatively complex and difficult to disassemble.

[0006] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows:

[0007] This application provides a water spraying device for a cleaning machine, comprising:

[0008] The upper support is equipped with an upper positioning part;

[0009] The lower support is detachably connected to the upper support; the lower support is provided with a lower positioning part.

[0010] The nozzle is rotatably disposed between the upper positioning part and the lower positioning part; the nozzle is provided with a water inlet and a water outlet that are connected to each other, and when the water entering the nozzle through the water inlet is sprayed out from the water outlet, it forms a driving force to drive the nozzle to rotate.

[0011] In one embodiment, the water outlet includes a plurality of power ports and a plurality of spray nozzles; the plurality of power ports are symmetrically arranged on the side wall of the nozzle; and the plurality of spray nozzles are all arranged on the upper surface of the nozzle.

[0012] Based on the above scheme, the symmetrical arrangement of the power ports ensures that the force generated when water is ejected from the power ports can drive the nozzle to rotate. The water ejected from the nozzles can be used for cleaning.

[0013] In one embodiment, there are two power ports, and the two power ports face opposite directions; there are four water spray nozzles, located in the front, back, left, and right directions of the nozzle.

[0014] Based on the above scheme, the opposite orientation of the two power ports ensures that the force generated by the sprayed water is in the same direction, facilitating the rotation of the nozzle. The water nozzles distributed in the four directions (front, back, left, and right) of the nozzle increase the spray area, resulting in a larger spray range.

[0015] In one embodiment, the lower edge of the upper support is provided with a buckle, and the upper edge of the lower support is provided with a buckle groove, wherein the buckle is detachably engaged in the buckle groove.

[0016] Based on the above solution, the structure of the buckle and the groove is relatively simple and the manufacturing process is easy.

[0017] In one embodiment, the upper positioning part is a protrusion located at the top center of the upper support and protruding downward; the upper end of the nozzle is provided with an upward protruding boss; when the nozzle is rotatably positioned between the upper positioning part and the lower positioning part, the boss is located directly below the protrusion.

[0018] Based on the above solution, the boss is located directly below the protrusion, which not only positions the top of the nozzle but also prevents the nozzle from moving upward when rotating, ensuring the stability of the nozzle during rotation.

[0019] In one embodiment, the lower positioning part is an extension tube disposed on the lower support and extending downward, and the inner wall of the extension tube is provided with an annular step; the lower end of the nozzle is provided with a plug tube extending downward along the edge of the water inlet; when the nozzle is rotatably disposed between the upper positioning part and the lower positioning part, the plug tube is inserted into the extension tube and is located directly above the annular step.

[0020] Based on the above solution, the annular step serves to position the lower part of the nozzle. Furthermore, the insertion tube at the lower end of the nozzle is inserted into the extension tube, providing good stability and ensuring that the nozzle will not easily detach from the extension tube during rotation.

[0021] In one embodiment, a water spraying device on a cleaning machine further includes a water inlet pipe, the upper end of which is inserted into the extension pipe and enters the spray head through the water inlet of the spray head; the insertion pipe is located between the extension pipe and the water inlet pipe.

[0022] Based on the above solution, the upper end of the water inlet pipe is inserted into the extension pipe and enters the nozzle through the water inlet of the nozzle, so that the water in the water inlet pipe can flow smoothly into the nozzle. The structure is relatively compact and can reduce the problem of water leakage in the water inlet pipe during the flow process.

[0023] In one embodiment, the outer wall of the water inlet pipe and near the insertion pipe is provided with an annular rib.

[0024] Based on the above scheme, the annular ribs can reduce the friction of the insertion pipe moving up and down, and increase the stability of the nozzle in the vertical direction and the circumferential flexibility when rotating.

[0025] In one embodiment, the extension pipe is provided with an L-shaped groove consisting of a horizontal groove and a vertical groove, and the water inlet pipe is provided with a locking block; the locking block slides along the vertical groove to the horizontal groove and locks at the horizontal groove.

[0026] Based on the above solution, the L-shaped slot and the locking block have a simple structure and are easy to operate, allowing for convenient installation and disassembly of the extension pipe and the water inlet pipe. Furthermore, the L-shaped slot and the locking block are relatively stable when engaged, thus making the connection between the extension pipe and the water inlet pipe more secure.

[0027] In one embodiment, the water inlet pipe is provided with a through hole located inside the nozzle, through which water in the water inlet pipe enters the nozzle and is sprayed out from the outlet.

[0028] Based on the above solution, the through hole allows water in the inlet pipe to enter the nozzle, and then spray out from the power port on the nozzle to complete the nozzle drive, and spray out from the water nozzle on the nozzle to complete the cleaning.

[0040] According to another aspect of this application, a flushing shelf is provided, including a shelf body, a liquid supply pipe and the aforementioned flushing assembly, wherein one of the liquid supply pipe and the main body section is inserted into the other.

[0041] In one embodiment, a limiting protrusion is provided on the outer peripheral surface of the inner side of the liquid supply pipe and the main body segment, and a limiting recess is provided on the inner wall surface of the outer side of the liquid supply pipe.

This structural design facilitates the smooth insertion of the inlet section into the expansion section, ensuring that the outer wall of the inlet section is adjacent to the inner wall of the expansion section, and the end of the inlet section is adjacent to the connecting platform. It also provides stable support for the rotation of the inlet section, ensuring that the rotary nozzle maintains good coaxiality around its axis within the expansion section, effectively avoiding the shaking problem that easily occurs when using an externally fixed water jet as the rotating shaft.

Detailed Implementation

[0073] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0074] It should be noted that in the water spraying device of the cleaning machine in this embodiment, the cleaning machine can be a dishwasher or a baby bottle cleaning machine, etc.

[0075] As shown in Figure 1, this embodiment provides a water spraying device for a cleaning machine, including:

[0076] Upper support 1, which is provided with an upper positioning part;

[0077] The lower support 2 is detachably connected to the upper support 1; the lower support 2 is provided with a lower positioning part.

[0078] The nozzle 3 is rotatably positioned between the upper positioning part and the lower positioning part; the nozzle 3 is provided with a connected water inlet and water outlet, and when the water entering the nozzle 3 through the water inlet sprays out from the water outlet, it forms a driving force to drive the nozzle 3 to rotate.

[0079] As shown in Figure 5, the water outlet includes several power ports 31 and several spray nozzles 32; the power ports 31 are symmetrically arranged on the side wall of the nozzle 3; the spray nozzles 32 are all arranged on the upper surface of the nozzle 3.

[0080] A more specific example of the power port 31 and the water nozzle 32 is as follows: there are two power ports 31, and the two power ports 31 face opposite directions; there are four water nozzles 32, located in the front, back, left and right directions of the nozzle 3.

[0081] The orientation of the nozzle 32 located on the nozzle 3 can be straight upward (the water jet from the nozzle 32 with this orientation is a straight column) or tilted upward (the water jet from the nozzle 32 with this orientation is an arc).

[0082] The power inlet 31 and the water nozzle 32 can be elongated or circular, etc.

[0083] A more specific example of upper support 1 is:

[0084] As shown in Figures 4 and 6, the upper positioning part is a protrusion 11 that is located at the top center of the upper support 1 and protrudes downward; the upper end of the nozzle 3 is provided with an upward protruding boss 33; when the nozzle 3 is rotated and positioned between the upper positioning part and the lower positioning part, the boss 33 is located directly below the protrusion 11.

[0085] The protrusion 11 has several outwardly extending arc-shaped plates 12 on its upper circumference, and the ends of the arc-shaped plates 12 are connected to an upper annular ring 13; the arc-shaped plates 12 and the upper annular ring 13 form an upper support 1, and the upper annular ring 13 is located at the lower edge of the upper support 1. There may be six arc-shaped plates 12.

[0086] A more specific example for lower support 2 is:

[0087] As shown in Figures 4 and 6, the lower positioning part is an extension tube 21 that is set on the lower support 2 and extends downward. The inner wall of the extension tube 21 is provided with an annular step 22. The lower end of the nozzle 3 is provided with a plug tube 34 that extends downward along the edge of the water inlet. When the nozzle 3 is rotated and set between the upper positioning part and the lower positioning part, the plug tube 34 is inserted into the extension tube 21 and is located directly above the annular step 22.

[0088] A lower annular ring 23 is provided above the extension tube 21, and several strip plates 24 are provided between the lower annular ring 23 and the upper opening of the extension tube 21. The strip plates 24, the lower annular ring 23, and the extension tube 21 form a lower support 2. The lower annular ring 23 is located at the upper edge of the lower support 2. There may be six strip plates 24.

[0089] In this embodiment, the detachable structure between the upper support 1 and the lower support 2 can be as follows: the lower edge of the upper support 1 is provided with a buckle 14, and the upper edge of the lower support 2 is provided with a buckle groove 25, and the buckle 14 can be detachably engaged in the buckle groove 25.

[0090] In one embodiment, the buckle 14 is located on the upper annular ring 13, and the buckle groove 25 is located on the lower annular ring 23. The buckles 14 and buckle grooves 25 correspond one-to-one, and the number of buckles 14 and buckle grooves 25 can be determined according to specific circumstances. The number of buckles 14 and buckle grooves 25 can be two, three, four, etc. In this embodiment, to ensure the stability of the connection between the upper support 1 and the lower support 2, six buckles 14 and six buckle grooves 25 are provided.

[0091] The interlocking structure of buckle 14 and buckle groove 25 is just one example of a detachable structure between upper support 1 and lower support 2. Other detachable structures between upper support 1 and lower support 2 are also possible, as long as they achieve a detachable connection between upper support 1 and lower support 2, they are all within the scope of protection of this application.

[0092] As shown in Figures 3 and 4, based on the above scheme, the water spraying device on the cleaning machine in this embodiment also includes a water inlet pipe 4. The upper end of the water inlet pipe 4 is inserted into the extension pipe 21 and enters the nozzle 3 through the water inlet of the nozzle 3; the insertion pipe 34 is located between the extension pipe 21 and the water inlet pipe 4.

[0093] The upper end of the water inlet pipe 4 is provided with a positioning protrusion 41, and the protrusion 33 of the nozzle 3 has a groove inside. When the upper end of the water inlet pipe 4 enters the nozzle 3, the positioning protrusion 41 is inserted into the groove. A through hole 42 is provided on the water inlet pipe 4 at a position inside the nozzle 3. Water in the water inlet pipe 4 enters the nozzle 3 through the through hole 42 and is sprayed out from the outlet. The through hole 42 is located below the positioning protrusion 41.

[0094] In addition, an annular rib 44 is provided on the outer wall of the water inlet pipe 4 near the insertion pipe 34. There are two ribs 44, and the two ribs 44 are arranged circumferentially on the outer wall of the water inlet pipe 4.

[0095] In this embodiment, the connection structure between the extension pipe 21 and the water inlet pipe 4 can be:

[0096] As shown in Figure 2, the extension pipe 21 is provided with an L-shaped slot 211 composed of a horizontal slot and a vertical slot, and the water inlet pipe 4 is provided with a locking block 43; the locking block 43 slides along the vertical slot to the horizontal slot and locks in the horizontal slot.

[0097] As shown in Figures 2 and 3, based on the above scheme, this embodiment of a water spraying device on a cleaning machine further includes a base 5, and a water inlet pipe 4 is disposed on the base 5. The lower end of the water inlet pipe 4 is provided with a water inlet 45, which is located at the bottom of the base 5. When the base 5 is installed in a cleaning machine (e.g., a baby bottle cleaning machine), the water inlet 45 is connected to a component (e.g., a water pump) in the cleaning machine that provides a water source.

[0098] The base 5 is square, and there are several round holes 51 distributed on the base 5, which are connected to the water inlet pipe 4.

[0099] The following is a further explanation of this application in conjunction with its working principle:

[0100] The nozzle 3 is located between the upper support 1 and the lower support 2, with the boss 33 on top of the nozzle 3 positioned directly below the protrusion 11 on the upper support 1. The insertion pipe 34 below the nozzle 3 is located between the extension pipe 21 and the water inlet pipe 4 on the lower support 2. When water from the cleaning machine enters the water inlet pipe 4, the water flows along the water inlet pipe 4 into the nozzle 3. The water flow sprayed through the power port 31 on the nozzle 3 provides power to the nozzle 3, driving it to rotate. The water flow sprayed through the spray nozzle 32 is used for cleaning. In addition, when water from the cleaning machine enters the water inlet pipe 4, some water will be sprayed out from the round hole 51 on the base 5 for cleaning.

[0101] In related technologies, cleaning equipment typically uses a rinsing assembly to rinse the items to be rinsed. However, the rotating nozzle of the rinsing assembly in related technologies relies on an external water jet as a pivot, which makes the rotating nozzle prone to shaking when rotating.

[0102] Referring to Figures 7 to 15, to address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides a flushing assembly. The flushing assembly includes an inlet pipe 100, a rotating nozzle 200, and a limiting cover 300. The inlet pipe 100 includes a main body section 110, a connecting platform 120, an expanding section 130, and a mounting platform 140 arranged sequentially. The diameter of the expanding section 130 is larger than the diameter of the main body section 110. The rotating nozzle 200 has a connection with the rotating nozzle... The internal components of the nozzle 200 include a drain hole 221 and an inlet section 230. There are multiple drain holes 221, which are spaced apart. The inlet section 230 is adjacent to the connecting platform 120, and the outer wall of the inlet section 230 is adjacent to the inner wall of the expansion section 130. The inlet section 230 is rotatably disposed within the expansion section 130 around its axis. The limiting cover 300 is installed on the mounting platform 140 and is used to limit the rotation of the nozzle 200 on the side away from the mounting platform 140.

[0103] In this embodiment, the rinsing component is used in a baby bottle cleaning machine and is used to rinse items 800 to be rinsed, such as baby bottles, nipples, breast pumps or other maternal and infant products; the rinsing component can also be used in small household cleaning machines (such as fruit and vegetable cleaning machines, dishwashing machines, dishwashers), commercial cleaning machines (such as car washing machines) or baby bottle steam cleaners.

[0104] The expanded diameter section 130 is coaxially arranged with the main body section 110. The outer diameter of the connecting platform 120 is larger than the outer diameter of the main body section 110 but smaller than the outer diameter of the expanded diameter section 130. The connecting platform 120 is a platform-shaped structure that is recessed relative to the expanded diameter section 130. The outer diameter of the mounting platform 140 is larger than the outer diameter of the expanded diameter section 130. The mounting platform 140 is a platform-shaped structure that is convex relative to the expanded diameter section 130. The connecting platform 120 and the mounting platform 140 can also be stepped structures or truncated cone structures.

[0105] The drain hole 221 is used to spray the flushing liquid inside the rotary nozzle 200 outward. The flushing liquid is water; the flushing liquid may also be a solution containing detergent, disinfectant liquid, or liquid mixed with gas.

[0106] The liquid inlet section 230 is part of the structure of the rotary nozzle 200. The liquid inlet section 230 is coaxially arranged with the expansion section 130. The liquid inlet section 230 protrudes from the inner wall surface of the rotary nozzle 200 toward the outside of the rotary nozzle 200. The end of the liquid inlet section 230 away from the rotary nozzle 200 is adjacent to the connecting platform 120, that is, the end face of the liquid inlet section 230 away from the rotary nozzle 200 is close to or near the surface of the connecting platform 120 near the rotary nozzle 200. The outer wall of the liquid inlet section 230 is adjacent to the inner wall of the expansion section 130, which means that the outer wall of the liquid inlet section 230 is close to or near the inner wall of the expansion section 130.

[0107] The limiting cover 300 can be fixedly installed on the mounting platform 140 through connection structures such as snap-fit, screw-fit, welding, fusion, plug-in, or riveting. A first limiting protrusion 310 is provided on the inner wall surface of the end of the limiting cover 300 away from the mounting platform 140, and a second limiting protrusion 222 is provided on the end of the rotating nozzle 200 away from the connecting platform 120. The limiting cover 300 limits the rotating nozzle 200 through the contact between the first limiting protrusion 310 and the second limiting protrusion 222, thereby restricting the deflection and / or offset of the rotating nozzle 200. Deflection of the rotating nozzle 200 refers to an unexpected angular tilt, oscillation, or torsion around its normal axis of rotation when the rotating nozzle 200 is rotating normally or stationary; offset of the rotating nozzle 200 refers to an unexpected positional movement along the axial or radial direction when the rotating nozzle 200 is rotating normally or stationary. The inner wall surface of the limit cover 300 at the end away from the mounting platform 140 and the end of the rotating nozzle 200 at the end away from the connecting platform 120 may also be provided with matching sleeves and end caps or guide bearings and shoulder retaining rings.

[0108] When the flushing assembly of this application flushes the item 800 to be flushed, the item 800 is first placed upside down on the flushing assembly so that the drain hole 221 of the rotating nozzle 200 extends into the interior of the item 800. Since the inlet section 230 of the rotating nozzle 200 is rotatably positioned within the expansion section 130, the flushing liquid can be sprayed in a 360° rotation inside the item 800, allowing the flushing liquid to reach all corners inside the item 800 (such as the bottom, inner wall, and top of the item 800). Furthermore, when flushing the item 800, the flushing assembly of this application can also directly position the drain hole 221 outside the item 800 to spray flushing liquid both inside and outside the item 800.

[0109] On the one hand, the connecting platform 120 of the inlet pipe 100 provides an axial positioning reference for the inlet section 230 of the rotary nozzle 200, while the expansion section 130 provides a radial positioning reference. The two work together to form a precise limiting space and positioning system. The above structural design facilitates the smooth insertion of the inlet section 230 into the expansion section 130, ensuring that the outer wall of the inlet section 230 is adjacent to the inner wall of the expansion section 130 and the end of the inlet section 230 is adjacent to the connecting platform 120. It also provides stable support for the rotation of the inlet section 230, ensuring that the rotary nozzle 200 always maintains good coaxiality around its axis within the expansion section 130, effectively avoiding the shaking problem that easily occurs when using an externally fixed water jet as the rotating shaft. At the same time, the limiting cover 300 installed on the mounting platform 140 forms an axial limit on the end of the rotary nozzle 200 away from the connecting platform 120, which can effectively suppress the deflection or axial displacement that may occur during the high-speed rotation of the rotary nozzle 200. The radial constraint of the connecting platform 120 and the expansion section 130, combined with the axial limitation of the limiting cover 300, enables the rotating nozzle 200 of the flushing assembly to rotate stably, thereby achieving continuous and uniform rotating flushing operation and ensuring the consistency and reliability of the flushing effect.

[0110] On the other hand, the flushing component of this application can achieve multi-angle comprehensive flushing, effectively reduce flushing dead corners, effectively improve cleaning effect, and improve flushing efficiency.

[0111] On the other hand, the flushing assembly includes an inlet pipe 100, a flushing nozzle, and a limiting cover 300. This segmented design not only facilitates the processing and assembly of each component, reducing production costs and difficulties, but also facilitates disassembly and replacement, reducing maintenance costs and difficulties.

[0112] Referring to Figures 12 to 14, in one embodiment, the direction of the axis of the enlarged diameter section 130 is the first direction, the extension direction of the drain hole 221 is intersected with the first direction and intersected with the second direction, and the second direction is perpendicular to the first direction.

[0113] In this embodiment, the angle between the extension direction of the drain hole 221 and the first direction is an acute angle, and the angle between the extension direction and the second direction is also an acute angle.

[0114] On the one hand, the extension direction of the drain hole 221 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 expansion section 130, this multi-angle spraying method not only effectively improves the comprehensiveness of the rinsing coverage and reduces rinsing dead angles, but also forms oblique or multi-angle rinsing on the same position of the item 800 to be rinsed, effectively improving the cleaning effect on stubborn stains.

[0115] On the other hand, the extension direction of the drain hole 221 (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 expansion section 130 is generated. This force can form a rotational torque around the first direction, driving the rotating nozzle 200 to rotate automatically. This self-driven design not only simplifies the structure of the flushing assembly, but also allows the water spray trajectory to form a dynamic circular or spiral coverage range, avoiding local over-flushing or under-flushing caused by fixed spraying, and achieving uniform and comprehensive flushing.

[0116] In addition, the extension directions of the plurality of drainage holes 221 may be parallel to each other, or the extension directions of at least two of the plurality of drainage holes 221 may intersect.

[0117] Referring to Figures 13 and 14, in one embodiment, the rotary nozzle 200 further has a power hole 211 communicating with the interior of the rotary nozzle 200. The power hole 211 is spaced apart from the drain hole 221. The extending direction of the power hole 211 is parallel to the second direction, and the axis of the power hole 211 is spaced apart from the axis of the enlarged diameter section 130.

[0118] On one hand, the extension direction of the power orifice 211 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 expanded section 130). 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 the oblique water spray drive that relies solely on the drain orifice 221, the power orifice 211 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.

[0119] On the other hand, the drain hole 221 is responsible for achieving multi-angle spraying to ensure comprehensive flushing; while the power hole 211 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 expansion section 130, complementing the spray trajectory of the drain hole 221 and enhancing the cleaning effect.

[0120] In other embodiments, the rotary nozzle 200 may also have a spray hole that extends perpendicularly to the first direction to achieve vertical spraying of the flushing liquid.

[0121] Referring to Figures 16 and 17, in one embodiment, a first contact protrusion 231 is provided between the liquid inlet section 230 and the connecting platform 120. The first contact protrusion 231 is arranged circumferentially along one of the liquid inlet section 230 and the connecting platform 120, and is in line contact with the other.

[0122] In this embodiment, the first contact protrusion 231 is a contact ring, and it is arranged circumferentially around the end face of the liquid inlet section 230 near the connecting platform 120. The first contact protrusion 231 may also include a plurality of contact protrusions spaced apart circumferentially along the liquid inlet section 230, or the first contact protrusion 231 may also include a plurality of contact protrusions and contact strips spaced apart circumferentially along the liquid inlet section 230; in addition, the first contact protrusion 231 may also be disposed on the surface of the connecting platform 120 near the liquid inlet section 230.

[0123] Compared to surface contact, the line contact between the liquid inlet section 230 and the connecting platform 120 achieved through the first contact protrusion 231 not only reduces the contact area between the two, thereby reducing rotational friction resistance and improving rotational flexibility and durability, thus extending their service life, but also establishes a stable support structure between the liquid inlet section 230 and the connecting platform 120, thereby improving the axial support stiffness and stability of the rotating nozzle 200 and ensuring the stability of the spray trajectory.

[0124] In addition, the line contact provided by the first contact protrusion 231 can also form a sealing barrier between the liquid inlet section 230 and the connecting platform 120, which can prevent the flushing liquid from leaking outward from the gap between the liquid inlet section 230 and the connecting platform 120, ensuring that more flushing liquid in the rotating nozzle 200 is sprayed out from the drain hole 221, thereby improving the utilization rate of the flushing liquid.

[0125] In addition, the line contact design only needs to ensure the manufacturing accuracy of the first contact protrusion 231, without the need for high-precision machining of the entire surface of the liquid inlet section 230 and the connecting platform 120, which reduces the manufacturing difficulty and cost.

[0126] Referring to Figures 16 and 17, in one embodiment, a second contact protrusion 232 is provided between the liquid inlet section 230 and the expansion section 130. The second contact protrusion 232 is arranged circumferentially along one of the liquid inlet section 230 and the expansion section 130 and is in line contact with the other.

[0127] In this embodiment, the second contact protrusion 232 is a contact ring, and is disposed around the outer peripheral surface of the liquid inlet section 230 in the circumferential direction. The second contact protrusion 232 may also include a plurality of contact protrusions spaced apart in the circumferential direction of the liquid inlet section 230, or the second contact protrusion 232 may also include a plurality of contact protrusions and contact strips spaced apart in the circumferential direction of the liquid inlet section 230; in addition, the second contact protrusion 232 may also be disposed on the inner wall surface of the diameter expansion section 130.

[0128] Compared to surface contact, the second contact protrusion 232 enables line contact between the inlet section 230 and the expansion section 130. This not only reduces the contact area between the two sections, 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 section 230 and the expansion section 130, improving their concentricity and ensuring the stability of the injection trajectory.

[0129] In addition, the line contact provided by the second contact protrusion 232 can also form a sealing barrier between the liquid inlet section 230 and the expansion section 130, which can prevent the flushing liquid from leaking outward from the gap between the liquid inlet section 230 and the expansion section 130. When used in conjunction with the first contact protrusion 231, it can further ensure that more flushing liquid in the rotating nozzle 200 is sprayed out from the drain hole 221, thereby improving the utilization rate of the flushing liquid.

[0130] In addition, the line contact design only needs to ensure the manufacturing accuracy of the second contact protrusion 232, without the need for high-precision machining of the entire surface of the liquid inlet section 230 and the diameter expansion section 130, which reduces the manufacturing difficulty and cost.

[0131] Referring to Figures 12 to 14, in one embodiment, the rotary nozzle 200 further includes a first rotary shell 210 and a second rotary shell 220. The surface of the second rotary shell 220 near the first rotary shell 210 is kept in contact with the surface of the first rotary shell 210 near the second rotary shell 220. The second rotary shell 220 and the first rotary shell 210 are integrally formed or fixedly connected.

[0132] In this embodiment, the second rotating shell 220 is located on the side of the first rotating shell 210 away from the connecting platform 120. The liquid inlet section 230 is disposed on the first rotating shell 210, and the second limiting protrusion 222 is disposed on the second rotating shell 220. The internal space of the second rotating shell 220 is in communication with the internal space of the first rotating shell 210 to form the inner cavity of the rotating nozzle 200. The drain hole 221 is disposed on the second rotating shell 220, and the power hole 211 is disposed on the first rotating shell 210. The drain hole 221 and the power hole 211 can also be disposed on one of the first rotating shell 210 and the second rotating shell 220, or the drain hole 221 can be disposed on the first rotating shell 210 and the power hole 211 can be disposed on the second rotating shell 220. It depends on the actual needs and is not limited here.

[0133] On the one hand, by splitting the rotating nozzle 200 into a first rotating shell 210 and a second rotating shell 220, the required structures can be processed on the two rotating shells respectively, ensuring that the different structures do not interfere with each other.

[0134] On the other hand, the surface of the second rotating shell 220 near the first rotating shell 210 and the surface of the first rotating shell 210 near the second rotating shell 220 are kept in close contact. This structural design makes the internal space of the rotating nozzle 200 a closed space. This closed structure can effectively ensure that the pressure of the flushing liquid is retained inside, and ensure that the flushing liquid sprayed from the drain hole 221 and the power hole 211 has sufficient spray pressure. This not only ensures the flushing effect, but also provides stable rotation power for the rotating nozzle 200, ensuring its rotation effect.

[0135] On the other hand, the second rotating shell 220 and the first rotating shell 210 adopt an integral molding design. This structure not only simplifies the processing and manufacturing process of the rotating nozzle 200 and reduces production difficulty, but also improves the connection strength and stability of the overall structure of the rotating nozzle 200, reducing the risk of failure caused by assembly gaps or loose parts. At the same time, the second rotating shell 220 and the first rotating shell 210 can also be fixedly connected by connection structures such as snap-fit ​​structure, screw structure, welding structure, fusion structure, plug-in structure or riveting structure.

[0136] Furthermore, for ease of processing and manufacturing, the second rotating shell 220 has the same basic structure as the first rotating shell 210.

[0137] Referring to Figures 10 to 14, in one embodiment, a limiting cover 300 covers the rotating nozzle 200 and is provided with a first liquid outlet through hole 320 that connects the inside and outside of the limiting cover 300.

[0138] In this embodiment, the limiting cover 300 completely covers the rotating nozzle 200, and there are multiple first liquid outlet holes 320, which are arranged at intervals along the circumference of the limiting cover 300.

[0139] When the flushing assembly sprays flushing liquid outward, the flushing liquid is first delivered into the rotating nozzle 200, and then sprayed out of the rotating nozzle 200 through the drain hole 221 and the power hole 211; during this process, the sprayed flushing liquid will be ejected out of the flushing assembly through the first liquid outlet hole 320.

[0140] On the one hand, the limiting cover 300 not only physically covers the rotating nozzle 200, preventing the item to be rinsed 800 or other external parts from directly contacting the high-speed rotating nozzle 200 and reducing the risk of damage caused by collision; it also reduces the risk of impurities clogging the drain hole 221 on the rotating nozzle 200 during rinsing and extends the service life of the rotating nozzle 200.

[0141] On the other hand, the first liquid outlet orifice 320 provides a directional outflow channel for the flushing liquid ejected from the rotating nozzle 200. By rationally designing the position, number, and angle of the first liquid outlet orifice 320, the spray direction of the flushing liquid can be guided or constrained, reducing energy waste caused by irregular scattering of the flushing liquid and allowing the flushing liquid to act more concentratedly on the area to be flushed, further expanding the effective flushing range or enhancing the local flushing intensity. At the same time, it also effectively blocks the splashing liquid generated during high-pressure jetting and nozzle rotation, optimizing the working environment.

[0142] Referring to Figures 10, 13, and 14, in one embodiment, the shape of the projection surface of the rotating nozzle 200 onto the preset projection surface is a rhombus, a quadrangular star, or a pentagonal star, and the shape of the projection surface of the limiting cover 300 onto the preset projection surface is a circle. The preset projection surface is perpendicular to the axis of the expansion section 130.

[0143] In this embodiment, the preset projection surface is parallel to the end face of the expansion section 130, and there is a rotation gap between the outer surface of the rotating nozzle 200 and the inner wall surface of the limiting cover 300. 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 other polygons, a circle, a triangular star, a hexagonal star, or other polygonal star shapes. No further restrictions are imposed here, and the shape depends on actual needs.

[0144] On the one hand, the star-shaped / diamond-shaped projection of the rotating nozzle 200 has a multi-directionally extending corner structure. During rotation, the spray trajectory of the drain hole 221 of the rotating nozzle 200 can cover a wider radial area. On the other hand, the circular projection of the limiting cover 300 provides a containment boundary for this irregular spray, reducing the risk of pressure loss due to excessive scattering of the flushing liquid. The combination of the two allows the flushing liquid to form a double coverage effect of dense coverage at the center and extended coverage at the corners within a circular range, reducing the flushing blind spots that are prone to occur in traditional circular nozzles.

[0145] On the other hand, during the rotation process, the different sides and corners of the star-shaped / diamond-shaped rotating nozzle 200 alternately pass through the same area, so that the flushing liquid forms a periodic sweeping effect within the circular range, reducing the risk of local liquid accumulation or thinning that may occur in the rotating nozzle 200; while the circular limiting cover 300 further confines this periodic spray within the regular boundary, ensuring that the flushing liquid distribution in the overall flushing area is more uniform and improving the consistency of the flushing effect.

[0146] In addition, the outer peripheral surface of the rotating nozzle 200 is irregularly undulating and has protrusions, while the outer peripheral surface of the rotating nozzle 200 can also be regularly undulating and can also have depressions.

[0147] Referring to Figures 10, 13 and 14, in one embodiment, the projection surface of the mounting platform 140 onto the preset projection surface is the first projection surface, and the projection surface of the limiting cover 300 onto the preset projection surface is the second projection surface. The first projection surface completely covers the second projection surface, and the preset projection surface is perpendicular to the axis of the expansion section 130.

[0148] In this embodiment, the area of ​​the first projection surface is equal to the area of ​​the second projection surface, and the area of ​​the second projection surface may be greater than the area of ​​the first projection surface.

[0149] The mounting platform 140 serves as the supporting foundation for the limiting cover 300. Its projected surface completely covers the projected surface of the limiting cover 300, meaning that the radial dimension of the mounting platform 140 is greater than or equal to that of the limiting cover 300. This provides the limiting cover 300 with more ample installation space and support area. This structural design can disperse the forces on the limiting cover 300 (such as the vibration and impact force when the rotating nozzle 200 rotates, the reaction force of the flushing liquid spray, etc.), reducing the risk of the limiting cover 300 loosening or deforming due to excessive local stress, thereby enhancing the structural stability of the entire flushing assembly.

[0150] Referring to Figures 18 and 19, in one embodiment, one of the limiting cover 300 and the mounting platform 140 is provided with a locking strip and / or a locking block 330, and the other is provided with a locking groove 141, wherein the locking strip and / or the locking block 330 is inserted into the locking groove 141.

[0151] In this embodiment, a plurality of locking blocks 330 are provided on the outer peripheral surface of the limiting cover 300, spaced apart along its own axial direction, and the mounting platform 140 is provided with the same number of locking slots 141 as the locking blocks 330. The outer peripheral surface of the limiting cover 300 may also be provided with annular locking strips arranged along its own axial direction, and the mounting platform 140 is provided with annular locking slots 141; the outer peripheral surface of the limiting cover 300 may also be provided with locking blocks 330 and arc-shaped locking strips arranged circumferentially, and the mounting platform 140 is provided with corresponding locking slots 141. Furthermore, the locking strips and / or locking blocks 330 may be mounted on the mounting platform 140, and the locking slots 141 are provided on the limiting cover 300.

[0152] With the cooperation of the locking strip and / or locking block 330 with the locking slot 141, the limit cover 300 and the mounting platform 140 can be quickly aligned and fixed without the need for additional fasteners or complicated tools, thus shortening the assembly and disassembly time of the limit cover 300 and the mounting platform 140.

[0153] Meanwhile, when the rotary nozzle 200 needs to be inspected, the limiting cover 300 can be easily disassembled by applying appropriate external force to separate the snap-fit ​​structure without damaging any parts, which improves the convenience of maintaining and replacing the rotary nozzle 200.

[0154] Referring to Figures 13 and 14, in one embodiment, the main body section 110, the connecting platform 120, the diameter-expanding section 130, and the mounting platform 140 are integrally formed parts.

[0155] The liquid inlet pipe 100 adopts an integral molding design. This structure not only simplifies the processing and manufacturing process of the liquid inlet pipe 100 and reduces the production difficulty, but also improves the connection strength and stability of the overall structure of the liquid inlet pipe 100, and reduces the risk of failure caused by assembly gaps or loose parts.

[0156] Referring to Figures 10 and 19, in one embodiment, a second liquid outlet hole 142 is provided on the surface of the mounting platform 140 near the limiting cover 300, and the second liquid outlet hole 142 extends to the surface of the mounting platform 140 away from the limiting cover 300.

[0157] In this embodiment, there are multiple second liquid outlet holes 142, which are spaced apart along the circumference of the mounting platform 140.

[0158] The second liquid outlet 142, used in conjunction with the first liquid outlet 320, not only helps to widen the spray range of the flushing component, reduce flushing blind spots, and improve the comprehensiveness of flushing, but also allows for timely drainage of any accumulated liquid, reducing the risk of flushing liquid buildup in localized areas and optimizing the drainage efficiency of the flushing liquid.

[0159] Referring to Figures 7 to 20, according to another aspect of this application, an embodiment of this application also provides a flushing shelf, which includes a shelf body 400, a liquid supply pipe 500, and the aforementioned flushing assembly, wherein one of the liquid supply pipe 500 and the main body segment 110 is inserted into the other.

[0160] In this embodiment, the frame body 400 is used not only to support the liquid supply pipe 500, but also to support the item 800 to be rinsed. The liquid supply pipe 500 is inserted into the main body section 110 with an interference fit, and after passing through the liquid inlet section 230, it is inserted into the rotating nozzle 200. The liquid supply pipe 500 can also be intermittently inserted into the main body section 110, and the main body section 110 can also be inserted into the liquid supply pipe 500.

[0161] The plug-in connection structure allows for quick docking of the liquid supply pipe 500 with the main body section 110 without the need for complex fasteners or seals, simplifying the assembly steps of the flushing rack and reducing installation difficulty.

[0162] Meanwhile, when the flushing components or the liquid supply pipe 500 malfunction (such as blockage or damage), the insert structure allows for quick separation of the two, enabling individual replacement of damaged parts without disassembling the entire shelf, thus reducing maintenance costs and difficulty.

[0163] In addition, the above structural design also supports flexible matching of flushing components of different specifications with liquid supply pipes 500, which makes it easy to upgrade or replace parts according to flushing needs, improve the flexibility of the flushing rack and the overall service life.

[0164] Referring to Figures 19 to 22, in one embodiment, a limiting protrusion 510 is provided on the outer peripheral surface of the inner side of the liquid supply pipe 500 and the main body segment 110, and a limiting recess 111 is provided on the inner wall surface of the outer side. The limiting recess 111 includes an inlet / outlet channel 1111 and a limiting groove 1112 that are connected to each other. The extending direction of the inlet / outlet channel 1111 intersects the extending direction of the limiting groove 1112. The limiting protrusion 510 enters into the limiting groove 1112 through the inlet / outlet channel 1111 and maintains contact with the two inner wall surfaces of the limiting groove 1112 that are arranged opposite to each other along the axial direction of the main body segment 110.

[0165] In this embodiment, the limiting protrusion 510 is disposed on the outer peripheral surface of the liquid supply pipe 500 and is integrally formed with the liquid supply pipe 500; the limiting recess 111 is disposed on the inner wall surface of the main body section 110 and extends through to the outer peripheral surface of the main body section 110. The inlet / outlet channel 1111 is an inlet / outlet through hole, and the extending direction of the inlet / outlet channel 1111 is perpendicular to the extending direction of the limiting groove 1112. The angle between the extending direction of the inlet / outlet channel 1111 and the extending direction of the limiting groove 1112 can also be an acute angle. In addition, the limiting protrusion 510 can be an elastic member and can enter into the inlet / outlet channel 1111 by elastic deformation. In this case, the inlet / outlet channel 1111 does not need to extend to the end face of the main body section 110 away from the connecting platform 120.

[0166] After the limiting protrusion 510 enters the limiting groove 1112, it comes into close contact with the inner walls on both sides of the limiting groove 1112 along the axial direction of the main body section 110, forming a rigid limit. This can effectively block the relative displacement between the liquid supply pipe 500 and the main body section 110 in the axial direction, improve the connection strength and stability between the liquid supply pipe 500 and the flushing assembly, and ensure that the liquid supply operation continues to be stable.

[0167] Meanwhile, the inlet / outlet channel 1111 and the limiting groove 1112 used in conjunction not only have the dual advantages of quick disassembly and assembly and reliable positioning, but also can be disassembled and assembled without complicated operations, simplifying the disassembly and assembly operations and reducing the difficulty of assembly and maintenance.

[0168] Referring to Figures 19 and 22, in one embodiment, the extension direction of the inlet / outlet channel 1111 is parallel to the axial direction of the main body segment 110 and extends to the end face of the main body segment 110 away from the connecting platform 120, and the extension direction of the limiting groove 1112 is parallel to the circumferential direction of the main body segment 110.

[0169] When assembling the liquid supply pipe 500 and the flushing assembly, first align the inlet / outlet channel 1111 with the limiting protrusion 510, then move the main body section 110 toward the liquid supply pipe 500. After the limiting protrusion 510 is inserted into the inlet / outlet channel 1111, continue to move the main body section 110 radially. When the limiting protrusion 510 moves to the area on the inlet / outlet channel 1111 that corresponds to the limiting groove 1112, move the main body section 110 along the extension direction of the limiting groove 1112 until the limiting protrusion 510 contacts the inner wall surface of the limiting groove 1112 and then stop moving. At this point, the assembly is complete.

[0170] When separating the liquid supply pipe 500 from the flushing assembly, the main body section 110 is first moved along the extension direction of the limiting groove 1112 toward the inlet / outlet channel 1111. After the limiting protrusion 510 moves to the inlet / outlet channel 1111, the main body section 110 is moved away from the liquid supply pipe 500. After the limiting protrusion 510 is disengaged from the inlet / outlet channel 1111, the liquid supply pipe 500 is also separated from the flushing assembly.

[0171] Referring to FIG21, in one embodiment, the limiting protrusion 510 has a guide slope 511, the surface of the limiting protrusion 510 near the diameter expansion section 130 is a first surface 512, the surface of the limiting protrusion 510 away from the diameter expansion section 130 is a second surface 513, and the limiting protrusion 510 also has a third surface 514 disposed adjacent to the first surface 512 and the second surface 513; the guide slope 511 is located between the first surface 512 and the third surface 514, and gradually slopes from the first surface 512 to the second surface 513 towards the third surface 514.

[0172] In this embodiment, after the limiting protrusion 510 is inserted into the limiting groove 1112, the third surface 514 is disposed corresponding to the inner wall surface of the limiting groove 1112 that is away from the inlet / outlet channel 1111.

[0173] The guide ramp 511 not only guides and directs the limiting protrusion 510 as it enters the inlet / outlet channel 1111, improving assembly smoothness, but also converts the axial or radial thrust of the main body section 110 into a portion of the lateral force during assembly, allowing the limiting protrusion 510 to enter the inlet / outlet channel 1111 more smoothly and reducing assembly resistance.

[0174] Referring to Figures 19 and 20, in one embodiment, there are multiple limiting protrusions 510, which are spaced apart circumferentially along the main body segment 110; the number of limiting recesses 111 is the same as the number of limiting protrusions 510, and the multiple limiting protrusions 510 are respectively provided in one-to-one correspondence with the multiple limiting recesses 111.

[0175] In this embodiment, there are two limiting protrusions 510, which are evenly distributed along the circumference of the main body segment 110; the number of limiting protrusions 510 may also be three, four or more.

[0176] The multiple limiting protrusions 510 and multiple limiting recesses 111 arranged circumferentially along the main body section 110 work together to not only balance the force distribution and improve the strength and stability of the connection between the liquid supply pipe 500 and the flushing component, but also form multi-point positioning constraints to improve positioning accuracy and ensure that the liquid supply pipe 500 and the main body section 110 maintain good coaxiality.

[0177] Referring to Figures 14 and 20, in one embodiment, the liquid supply pipe 500 has a support protrusion 520, and the inner wall surface of the rotating nozzle 200 is provided with a support groove 223; the support protrusion 520 passes through the support groove 223 and contacts or makes point contact with the bottom line of the groove 223.

[0178] In this embodiment, the supporting protrusion 520 is a supporting protrusion, and the supporting groove 223 is disposed on the inner wall surface of the second rotating shell 220 near the first rotating shell 210; the supporting protrusion 520 and the bottom of the supporting groove 223 are in point contact. The supporting protrusion 520 and the supporting groove 223 can also be in line contact. In addition, under the cooperation of the supporting protrusion 520 and the supporting groove 223, there is a rotational gap between the liquid inlet section 230 and the connecting platform 120, and there is a rotational gap between the liquid inlet section 230 and the expansion section 130. At this time, it is also feasible that there is no first contact protrusion 231 between the liquid inlet section 230 and the connecting platform 120, and it is also feasible that there is no second contact protrusion 232 between the liquid inlet section 230 and the expansion section 130.

[0179] The supporting protrusion 520 and supporting groove 223 used in conjunction are in line contact or point contact. This provides radial restraint for the rotating nozzle 200, preventing excessive offset or wobbling during rotation and ensuring the stability of the rotation trajectory. Furthermore, by minimizing the contact area (compared to surface contact), it significantly reduces frictional resistance, allowing the rotating nozzle 200 to rotate more smoothly under the power of the flushing liquid, reducing the risk of jamming or speed reduction due to excessive friction. In addition, compared to surface contact structures that require high-precision fit, line contact or point contact places lower requirements on the machining accuracy of the supporting protrusion 520 and supporting groove 223.

[0180] In addition, a plurality of liquid supply holes 530 are provided on the outer circumferential surface of the section of the liquid supply pipe 500 that extends into the interior of the rotary nozzle 200. The liquid supply holes 530 are connected to the interior of the liquid supply pipe 500. The plurality of liquid supply holes 530 are spaced apart along the circumference of the liquid supply pipe 500.

[0181] Referring to Figures 13 to 15, in one embodiment, the liquid supply pipe 500 is inserted into the main body section 110, and the liquid inlet section 230 is sleeved on the outer periphery of the liquid supply pipe 500. A contact protrusion 540 is provided between the liquid supply pipe 500 and the liquid inlet section 230. The contact protrusion 540 is arranged circumferentially along one of the liquid supply pipe 500 and the liquid inlet section 230 and is in line contact with the other.

[0182] In this embodiment, the contact protrusion 540 is disposed on the outer peripheral surface of the liquid supply pipe 500 and is a contact protrusion ring disposed along the circumference of the liquid supply pipe 500. The contact protrusion 540 may also include a plurality of contact protrusions disposed at intervals along the circumference of the liquid supply pipe 500, or the contact protrusion 540 may also include a plurality of contact protrusions and contact protrusions disposed at intervals along the circumference of the liquid supply pipe 500. In addition, the contact protrusion 540 may also be disposed on the inner wall surface of the liquid inlet section 230.

[0183] On the one hand, the sequentially nested liquid supply pipe 500, liquid inlet section 230 and diameter expansion section 130 form a stable hierarchical support structure, which enables the rotary nozzle 200 to effectively resist the external forces generated by the vibration of the rotary nozzle 200 and the impact of liquid during the flushing process, ensuring the stability of the rotation of the rotary nozzle 200.

[0184] On the other hand, compared to surface contact, the line contact between the inlet section 230 and the supply pipe 500 achieved through the contact protrusion 540 not only reduces the contact area between the two, thereby reducing rotational friction resistance and improving rotational flexibility and durability, thus extending their service life, but also forms a sealing barrier between the inlet section 230 and the supply pipe 500. This prevents the flushing liquid from leaking outward from the gap between the inlet section 230 and the supply pipe 500, ensuring that more flushing liquid in the rotating nozzle 200 is ejected from the drain hole 221, thus improving the utilization rate of the flushing liquid.

[0185] In addition, to further reduce the friction between the liquid supply pipe 500 and the liquid inlet section 230, there are multiple contact protrusions 540, and the multiple contact protrusions 540 are spaced apart along the axial direction of the liquid supply pipe 500.

[0186] Referring to Figures 7 to 9 and Figure 11, in one embodiment, the flushing shelf further includes a liquid supply seat 600, which is disposed on the shelf body 400; there are multiple flushing components and liquid supply pipes 500, which are spaced apart around the axis of the liquid supply seat 600 and are connected to the liquid supply pipes 500.

[0187] In this embodiment, the liquid supply seat 600 is fixedly installed on the frame body 400, and multiple liquid supply pipes 500 are evenly spaced around the axis of the liquid supply seat 600, with the axis of the liquid supply pipes 500 parallel to the axis of the liquid supply seat 600; the multiple liquid supply pipes 500 can also be distributed in a straight line or a curve; the flushing assembly can also be provided with only one set.

[0188] In addition, the number of liquid supply pipes 500 is the same as the number of flushing components, or the number of liquid supply pipes 500 may differ from the number of flushing components, depending on actual needs, and is not limited here.

[0189] Multiple flushing components are positioned at different locations and heights according to the structural layout of the item 800 to be flushed. After being uniformly supplied with water through the liquid supply base 600, the rotating nozzles 200 of each flushing component can spray water from multiple angles. Each rotating nozzle 200 is responsible for flushing a different area, ensuring that the item 800 to be flushed is fully flushed. Compared with a single flushing component, this multi-directional coordinated flushing can cover the inner and outer surfaces, corners, and crevices of the item 800 to be flushed, avoiding local omissions and improving flushing efficiency and coverage. At the same time, centralized water supply through the liquid supply base 600 not only reduces pipeline complexity but also facilitates unified maintenance and reduces maintenance costs.

[0190] Referring to Figures 7 to 22, according to another aspect of this application, an embodiment of this application provides a cleaning device, which includes a mounting base 700 and the aforementioned flushing rack. The mounting base 700 has a mounting groove 710, and the flushing rack is disposed within the mounting groove 710.

[0191] In this embodiment, the cleaning equipment is a baby bottle cleaner. The cleaning equipment can also be a small household cleaner (such as a fruit and vegetable cleaner, dishwashing machine, or dishwasher), a commercial cleaner (such as a car wash machine), or a baby bottle steam cleaner. The rinsing rack is installed within the mounting recess 710.

[0192] The mounting base 700 serves as a load-bearing foundation, providing rigid support for the rinsing rack and effectively reducing the risk of the rack shaking or tilting due to the placement of items 800 to be rinsed or impact from the rinsing liquid. Meanwhile, the mounting groove 710 not only accommodates the rinsing rack, optimizing the layout of the cleaning equipment and reducing its size, but also provides a protective enclosure for the rack.

[0193] Referring to FIG7, in one embodiment, the cleaning equipment further includes a protective cover 720, which is pivotally connected to the mounting for covering the flushing rack.

[0194] In summary, implementing the flushing assembly, flushing rack, and cleaning equipment provided in this embodiment has at least the following beneficial technical effects: On the one hand, the flushing assembly of this application can achieve multi-angle comprehensive flushing, effectively reduce flushing dead angles, effectively improve the cleaning effect, and improve flushing efficiency.

[0195] On the other hand, the connecting platform 120 of the inlet pipe 100 provides an axial positioning reference for the inlet section 230 of the rotary nozzle 200, while the expansion section 130 provides a radial positioning reference. The two work together to form a precise limiting space and positioning system. The above structural design facilitates the smooth insertion of the inlet section 230 into the expansion section 130, ensuring that the outer wall of the inlet section 230 is adjacent to the inner wall of the expansion section 130 and the end of the inlet section 230 is adjacent to the connecting platform 120. It also provides stable support for the rotation of the inlet section 230, ensuring that the rotary nozzle 200 always maintains good coaxiality around its axis within the expansion section 130, effectively avoiding the shaking problem that easily occurs when using an externally fixed water jet as a rotating shaft.

[0196] Meanwhile, the limiting cover 300 installed on the mounting platform 140 forms an axial limit on the end of the rotating nozzle 200 away from the connecting platform 120, which can effectively suppress the deflection or axial displacement that may occur during the high-speed rotation of the rotating nozzle 200. Through the radial constraint of the connecting platform 120 and the expansion section 130, combined with the axial limit of the limiting cover 300, the rotating nozzle 200 of the flushing assembly can achieve stable rotation, thereby realizing continuous and uniform rotating flushing operation, ensuring the consistency and reliability of the flushing effect.

[0197] On the other hand, the flushing assembly includes an inlet pipe 100, a flushing nozzle, and a limiting cover 300. This segmented design not only facilitates the processing and assembly of each component, reducing production costs and difficulties, but also facilitates disassembly and replacement, reducing maintenance costs and difficulties.

[0198] This application is not limited to the above-mentioned optional implementation methods. Under the premise of not conflicting with each other, the solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this application. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this application shall fall within the protection scope of this application.
