[0026] refer to Figure 1 , Figure 2 The present application proposes a cleaning device, which includes an outer shell 100, a base 110, a shelf assembly 200 and a spray assembly 300.

[0027] The outer shell 100 is a shell structure, in which a washing cavity is formed. A cover is provided on the outer shell 100 for sealing the washing cavity.

[0028] The base 110 is disposed at the bottom of the outer shell 100 to provide a support foundation for the entire cleaning device.

[0029] An installation cavity is formed in the base 110 , and a water supply component is disposed in the installation cavity.

[0030] The water supply component is mainly used to supply water to the washing cavity, and includes a water supply pump. In addition to the water supply component, a drainage component is also installed in the cavity to drain the water in the washing cavity.

[0031] The cleaning equipment also includes a water tank 120, which is specifically a clean water tank 120 for connecting to a water supply component. Of course, the cleaning equipment may also be provided with a sewage tank 120 for connecting to a drainage component to temporarily store sewage. Alternatively, the drainage component of the cleaning equipment involved in the present application may be externally connected to a drainage pipe group to directly discharge the sewage.

[0032] The shelf assembly 200 is disposed in the washing cavity. The shelf assembly 200 at least includes a first shelf 210 disposed at the bottom of the washing cavity, and is used to support the items 400 to be cleaned.

[0033] Combination Figure 3 , Figure 4 , Fig.14 as well as Fig.17 In some embodiments, the spray assembly 300 includes a support member and at least two replaceable spray members 320 .

[0034] Specifically, any replaceable spray component 320 is detachably connected to the top of the support component via an adapter, and each replaceable spray component 320 has a different spray structure. Different replaceable spray components 320 are connected to the support component for parts 400 to be cleaned of different shapes.

[0035] In another embodiment, the spray assembly 300 includes a bottom spray member 310 , at least two replaceable spray members 320 , and a support member 330 disposed between the bottom spray member 310 and the replaceable spray members 320 .

[0036] The bottom spray member 310 is disposed on the upper side or the lower side of the first rack 210 and connected to the water supply assembly. A spray hole 322 opening toward the first rack 210 is formed on the bottom spray member 310. The bottom spray member 310 outputs washing water upward to clean the items 400 to be cleaned.

[0037] Reference again Figure 2 , Figure 3 In some embodiments of the present application, the shelf assembly 200 specifically includes a first shelf 210 and a second shelf 220, that is, at least a double-layer support structure is provided in the washing cavity.

[0038] The first rack 210 and the second rack 220 are arranged at intervals along the depth direction of the washing cavity, and the replaceable spray member 320 is located between the first rack 210 and the second rack 220 .

[0039] The bottom spraying member 310 may be configured as a fixed structure, or may be rotatably connected above or below the first shelf 210 .

[0040] The spray holes 322 on the bottom spray member 310 are arranged in the same inclined direction. In the washing state, under the reaction of the washing water output from the spray holes 322, the bottom spray member 310 rotates to evenly spray the washing water into the washing cavity to wash the items to be washed.

[0041] In addition to spraying and cleaning the items to be cleaned 400 on the first rack 210 together with the bottom spray member 310, the replaceable spray member 320 can also clean the items to be cleaned 400 on the second rack 220 according to the actual needs of the user to improve the cleaning efficiency.

[0042] The second rack 220 is detachably connected to the washing cavity to facilitate the placement of the items to be cleaned 400 on the first rack 210. Specifically, an inner supporting protrusion extending into the washing cavity is formed on the side wall of the washing cavity, and the second rack 220 is supported on the inner supporting protrusion.

[0043] Of course, the second shelf 220 can also be connected in other detachable ways such as snaps. The specific connection is not the design focus of this application and will not be described in detail here.

[0044] The cleaning equipment has two layers of shelves, which can clean 400 items of different sizes in layers, with larger capacity and better cleaning effect; a spray part is arranged at the bottom of each shelf, which has high cleaning efficiency and reduces cleaning blind spots.

[0045] refer to Figure 6 In some embodiments of the present application, one of the replaceable spray parts 320 is a spray arm structure, on which a penetrating connecting hole 321 is formed. The replaceable spray part 320 specifically includes at least two spray arms arranged at equal angles along the circumference of the connecting hole 321, and each spray arm is formed with a spray channel, which is connected to the water supply channel through the connecting hole 321. Each spray arm is formed with a spray surface with the same direction, and a plurality of spray holes 322 are arranged at intervals on the spray surface. A sealing portion 350 is detachably connected to the connecting hole 321 for sealing the top of the connecting hole 321.

[0046] Specifically, when the second rack 220 is connected to the washing cavity, the replaceable spraying member 320 is configured with each spraying surface facing the second rack 220, so as to wash the items 400 to be washed on the second rack 220; When the second rack 220 is removed from the washing inner cavity, the replaceable spraying member 320 is configured with each spraying surface facing the first rack 210 , so as to clean the items 400 to be cleaned on the first rack 210 .

[0047] In other words, the replaceable spray component 320 can be installed on both sides according to actual washing requirements, that is, its spraying surface can face the second shelf 220 or the first shelf 210. After the replaceable spray component 320 is installed, it is only necessary to cover the covering part 350 on the connecting hole 321 to complete the adjustment of the specific spraying direction of the replaceable spray component 320.

[0048] The above-mentioned structure of the replaceable spray member 320 can realize the multifunctional washing of the cleaning equipment, and can perform up and down bidirectional cleaning on the items to be cleaned 400 on the first shelf 210 to improve the cleaning effect; the items to be cleaned 400 on the first shelf 210 and the second shelf 220 can also be cleaned respectively by the bottom spray member 310 and the replaceable spray member 320, with a large washing capacity, stronger versatility, and simple and convenient operation.

[0049] Combination Figure 7-Figure 11 In some embodiments of the present application, the replaceable spray member 320 is detachably connected to the top of the support member 330 through the adapter 340, a plurality of connecting portions 342 are formed on the peripheral side of the adapter 340, the spray channel is connected to the water supply channel through the corresponding connecting portions 342, the sealing portion 350 is connected to the adapter 340, and the replaceable spray member 320 is rotatably connected to the adapter 340.

[0050] The adapter 340 includes a first connection end 344 and a second connection end 341 . The first connection end 344 is a cylindrical structure, and the second connection end 341 is a cylindrical structure closed at the top. A penetrating connection channel is formed in the first connection end 344 and the second connection end 341 .

[0051] The first connection end 344 is sleeved on the top of the adjustable support unit 332 located at the top. Specifically, a snap-in hole 3321 is provided on the outer wall of the support member 330 located at the top, and a snap-in block 345 is provided on the inner wall of the second connection end 341. In the connected state, the snap-in block 345 is snapped into the snap-in hole 3321 to realize the connection and fixation between the second connection end 341 and the support member 330.

[0052] Specifically, a groove 246 is also provided on the second connecting end 341, and the groove 246 is specifically provided on both sides of the clamping block 345. A reset arc piece is formed between the two grooves 246. The reset arc piece has a certain deformation amount. When the second connecting end 341 is connected to the support member 330, the reset arc piece expands outward under the action of the clamping block 345 until the clamping block 345 is clamped into the clamping hole 3321. Then the reset arc piece is reset to reduce the friction between the second connecting end 341 and the support member 330 during the installation process, thereby improving the assembly efficiency.

[0053] In addition, specific reference Fig. 9In order to support and limit the replaceable spray component 320, a limiting protrusion 343 extending radially outward along the first connecting end 344 is formed between the first connecting end 344 and the second connecting end 341. The size of the connecting hole 321 of the replaceable spray component 320 is larger than the outer diameter of the second connecting end 341, and the outer diameter of the limiting protrusion 343 is larger than the connecting hole 321. The replaceable spray component 320 is sleeved on the adapter 340 from above the second connecting end 341 through the connecting hole 321, and can be rotatably connected above the limiting protrusion 343.

[0054] The second connection end 341 is a cylindrical structure with a top that is at least partially closed, and the communication portion 342 is formed on a peripheral side of the second connection end 341 .

[0055] The washing water transported upward from the water supply channel is transported to the spray channel through the connecting portion 342, and is finally output from the spray hole 322 on the spray arm.

[0056] The covering part 350 is specifically connected to the second connecting end 341, the outer diameter of the covering part 350 is adapted to the size of the connecting hole 321, the inner diameter is adapted to the outer diameter of the second connecting end 341, the covering part 350 is fixedly connected to the second connecting end 341, the covering part 350 is connected in the connecting hole 321, and the replaceable spray part 320 is rotatably connected relative to the covering part 350.

[0057] Specific reference Fig.10 A positioning outer edge 351 extending toward the circumferential side is also formed at the top of the cover portion 350. The positioning outer edge 351 is located on the outer side of the replaceable spray component 320 and is used to limit the replaceable spray component 320. It can also reduce the gap between the connecting hole 321 and the cover portion 350, thereby reducing the leakage of washing water from between the replaceable spray component 320 and the cover portion 350.

[0058] Then, the replaceable spraying member 320 is rotatably connected between the positioning outer edge 351 and the limiting protrusion 343 .

[0059] In some embodiments, the covering portion 350 is snapped onto the second connecting end 341, and a plurality of snap portions 352 are dispersedly arranged on the covering portion 350 along the circumferential direction. The snap portions 352 are specifically formed on the inner surface of the covering portion 350 and extend downward, and a snap-connecting portion 347 is formed on the second connecting end 341, and the snap-connecting portion 352 is connected to the corresponding snap-connecting portion 347.

[0060] Specifically, the clamping portion 347 is a clamping protrusion formed on the connecting portion 342 , and the buckle portion 352 is correspondingly connected to the clamping protrusion.

[0061] Combination Fig.12 , Fig.13In other embodiments, the cover part 350 is adsorbed on the adapter 340, a first adsorption part 361 is provided in the second connecting part, a second adsorption part 362 is provided in the cover part 350, and the second adsorption part 362 is connected to the first adsorption part 361 by magnetic attraction to realize a detachable connection between the cover part 350 and the adapter 340.

[0062] refer to Figure 14-16 In other embodiments, a spray end face is formed on one of the replaceable spray parts 320, and the spray end face is located at the far end where the replaceable spray part 320 is connected to the adapter, and a plurality of penetrating spray ports 323 are dispersedly arranged on the spray end face.

[0063] The number and specific size of the spray ports 323 are designed according to actual needs. The spray ports 323 are specifically through-flowing water ports formed on the spray end surface. The water flow in the water supply channel is directly output from the spray ports 323 to the washing inner cavity.

[0064] The replaceable spray member 320 is mainly used for the bottle-shaped article to be cleaned 400 with a larger opening size and a deeper depth. When in use, the article to be cleaned 400 is inverted on the first shelf, and the replaceable spray member 320 extends into the inner cavity of the article to be cleaned 400. In addition to the bottom spray member 310 located on the lower layer spraying the article to be cleaned 400 in a large area, the relatively concentrated water flow output from the spray port 323 on the replaceable spray member 320 can also strongly clean the inner cavity of the article to be cleaned 400.

[0065] In some embodiments, a plurality of snap-fit ​​portions 352 are dispersedly arranged along the circumferential direction on the inner side of the spray end surface of the replaceable spray member 320 , a snap-fit ​​portion 347 is formed on the second connecting end 341 , and the snap-fit ​​portion 352 is connected to the corresponding snap-fit ​​portion 347 .

[0066] The specific structures of the buckle portion 352 and the engaging portion 347 are similar to those in the above-mentioned embodiment and will not be described in detail here.

[0067] A first adsorption portion is disposed in the second connection end 341 , and a second adsorption portion is formed in the spray end surface. The second adsorption portion is connected to the first adsorption portion by magnetic attraction to achieve a detachable connection between the replaceable spray component 320 and the adapter.

[0068] It should be noted that in order to realize the transportation of the washing water in the adapter to the spray port 323 through the connecting portion 342, a sealing outer edge 3411 extending outward is formed on the side of the second connection end 341 close to the limiting protrusion 343. The size of the sealing outer edge 3411 is smaller than the limiting protrusion 343. The bottom of the replaceable spray part 320 is connected to the sealing outer edge 3411, and a flow gap is formed between the outer wall of the second connection end 341 and the inner wall of the replaceable spray part 320.

[0069] The water flow output from the connecting portion 342 is output to the outside through the flow gap, and is output through the spray port 323, the spray column 324 or the spray channel.

[0070] refer to Fig.17 , Fig.18 In some other embodiments, a spray end face is formed on one of the replaceable spray parts 320, and the spray end face is located at the distal end where the replaceable spray part 320 is connected to the adapter. A spray column 324 extending in a direction away from the adapter is formed on the spray end face, and a spray channel connected to the water supply channel is formed on the spray column 324.

[0071] The replaceable spray member 320 is different from the replaceable spray member 320 in the previous embodiment in that a spray column 324 extending upward is formed on the spray end surface.

[0072] The replaceable spraying member 320 is mainly used for bottle-shaped or tubular objects 400 to be cleaned with a smaller opening size.

[0073] During cleaning, the bottle-shaped or tubular part 400 to be cleaned with a smaller opening size is turned upside down onto the corresponding spray column 324. In addition to the bottom spray part 310 located at the lower layer spraying the part 400 to be cleaned over a large area, the more concentrated water flow output from the spray column 324 on the replaceable spray part 320 can also strongly clean the inner cavity of the part 400 to be cleaned.

[0074] The connection between the replaceable spraying member 320 and the adapter member may also be achieved by snapping or magnetic attraction.

[0075] The cleaning device involved in the present application includes at least two of the three replaceable spray parts 320 mentioned above, and the connection method between each replaceable spray part 320 and the adapter is unified to achieve a detachable connection.

[0076] Combined with 13, Fig.16 as well as Fig.18 In addition, in some embodiments, in order to reduce the vortex formed by the water flow at the lower side of the second connection end 341 and reduce the upward force on the second connection end 341, the present application forms a guide portion 348 extending in the direction of the water supply channel at the top of the second connection end 341, and the guide portion 348 is used to guide the water flow output from the water supply channel to the surrounding side.

[0077] The guide portion 348 is specifically a guide arc surface structure that gradually shrinks from the top peripheral side of the second connection end 341 toward the center direction. Under the action of the guide portion 348, the water flow is guided toward the connecting portion 342 on the peripheral side to reduce the force of the water flow on the second connection end 341.

[0078] In some embodiments, the height of the support member 330 is adjustable, thereby adjusting the height of the replaceable spray member 320 to adapt to the position of the object to be cleaned 400 in the washing cavity to improve the cleaning effect.

[0079] Specifically, when the height of the items to be cleaned 400 on the first rack 210 is relatively low, the height of the support member 330 is lowered, and the replaceable spray member 320 is moved above the items to be cleaned 400 toward the items to be cleaned 400, thereby increasing the impact force of the washing water sprayed from the replaceable spray member 320 on the items to be cleaned 400.

[0080] When the height of the items to be cleaned 400 on the first shelf 210 is relatively high, such as milk bottles, etc., the height of the support member 330 is adjusted to match the items to be cleaned 400.

[0081] Specific, combined Figure 5-Figure 7 The support member 330 includes at least two support units connected end to end. The support member 330 is configured to adjust the height of the support member 330 by changing the relative positions of adjacent support units. Specifically, the adjacent support units are movably connected by plug-in, and the height of the entire support member 330 is adjusted according to the plug-in depth between the adjacent support units.

[0082] A water supply channel is formed in the support member 330 , and the water supply channel is used to connect the bottom spray member 310 and the replaceable spray member 320 .

[0088] From top to bottom, the diameter of each adjustable support unit 332 gradually increases.

[0089] In order to limit the movement of the adjustable support unit 332 , a limiting recess 333 recessed into the water supply channel is formed on the bottom support unit 331 and / or the adjustable support unit 332 .

[0090] When the number of the adjustable support unit 332 is one, the bottom of the adjustable support unit 332 is inserted into the bottom support unit 331 and can move up and down within a certain range relative to the bottom support unit 331 .

[0091] Specifically, both ends of the bottom support unit 331 are respectively formed with limiting recesses 333 which are recessed into the water supply channel. The inner diameter of the limiting recess 333 is adapted to the outer wall size of the adjustable support unit 332 connected thereto. A positioning portion 334 is provided on the outer wall of one end of the adjustable support unit 332 extending into the bottom support unit 331. The positioning portion 334 and the corresponding limiting recess 333 are used to limit the maximum displacement of the adjustable support unit 332 relative to the bottom support unit 331.

[0092] When the number of the adjustable support units 332 is two or more, the adjustable support unit 332 at the bottom is plugged into the bottom support unit 331 , which is then plugged into adjacent adjustable support units 332 from top to bottom.

[0093] Except for the adjustable support unit 332 at the top that is directly connected to the spray element, at least one end of each of the other adjustable support units 332 is formed with a limiting recess 333 recessed into the water supply channel, and one end of each adjustable support unit 332 extending into the adjacent adjustable support unit 332 is provided with a positioning portion 334.

[0094] The inner diameter of the limiting recess 333 is matched with the outer wall size of the adjustable support unit 332 connected thereto, and a tight connection is formed between the limiting recess 333 and the adjustable support unit 332 connected thereto, thereby ensuring sealing and preventing water leakage.

[0095] When the adjustable support unit 332 moves up and down along the bottom support unit 331 or the adjacent adjustable support unit 332 , the positioning portion 334 connected thereto moves synchronously therewith until the positioning portion 334 contacts the limiting recess 333 , and the adjustable support unit 332 is adjusted into place.
