[0025] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[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 The spray assembly 300 includes a first spray member 310, a second spray member 320 and an adjustable support member 330 arranged between the first spray member 310 and the second spray member 320. The first spray member 310 is arranged below the first rack 210 and is connected to the water supply assembly. A spray hole 322 opening upward is formed on the first spray member 310. The first spray member 310 outputs washing water upward to clean the items 400 to be cleaned.

[0034] The first spraying member 310 may be configured as a fixed structure, or may be rotatably connected below the first shelf 210 .

[0035] The spray holes 322 on the first 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 first spray member 310 rotates to evenly spray the washing water into the washing cavity to wash the items to be washed.

[0036] The second spray member 320 is connected to the top of the first shelf 210 through an adjustable support member 330. The height of the adjustable support member 330 is adjustable, and the height of the second spray member 320 is further adjusted to adapt to the position of the object to be cleaned 400 in the washing cavity to improve the cleaning effect.

[0037] Specifically, when the height of the items to be cleaned 400 on the first rack 210 is low, the height of the adjustable support member 330 is lowered, and the second spray member 320 is above the items to be cleaned 400 and moves toward the items to be cleaned 400, thereby increasing the impact force of the washing water sprayed from the second spray member 320 on the items to be cleaned 400.

[0038] 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 adjustable support member 330 is adjusted to match the items to be cleaned 400 .

[0039] Specific, combined Figure 5-Figure 7The adjustable support member 330 includes at least two support units connected end to end. The adjustable support member 330 is configured to adjust the height of the adjustable 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 adjustable support member 330 is adjusted according to the plug-in depth between the adjacent support units.

[0040] A water supply channel is formed in the adjustable support member 330 , and the water supply channel is used to connect the first spray member 310 and the second spray member 320 .

[0041] In some embodiments, the adjustable support member 330 is vertically arranged, including a bottom support unit 331 connected to the first shelf 210 and at least one adjustable support unit 332 movably connected to the bottom support unit 331, the first spray member 310 is rotatably connected under the bottom support unit 331, and the second spray member 320 is rotatably connected to the adjustable support unit 332 located at the top.

[0042] For the convenience of processing, the bottom support unit 331 is designed to be integrally formed with the first shelf 210. Specifically, the bottom support unit 331 is a tubular structure formed in the middle of the first shelf 210 and extending upward. A through hole connected to the inner cavity of the bottom support unit 331 is also formed in the middle of the first shelf 210. The first spray piece 310 is connected to the bottom support unit 331 through the through hole.

[0043] The number of the adjustable support units 332 can be designed to be one or more than one according to actual design requirements.

[0044] 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 .

[0045] 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.

[0046] From top to bottom, the diameter of each adjustable support unit 332 gradually increases.

[0047] Combination Figure 6 , Figure 7 In some embodiments of the present application, the number of adjustable support units 332 can be designed to be one or more according to actual design requirements.

[0048] 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 .

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] Specifically, at least two positioning holes are arranged at equal angles along the circumferential direction of the adjustable support unit 332 at the lower position, and the positioning portion 334 is specifically a positioning arc plate, on which a positioning protrusion is formed, and the positioning portion 334 is connected to the outer wall of the adjustable support unit 332 through the positioning protrusion.

[0055] The positioning protrusion can be formed by stamping, and the installation of the bottom support unit 331 and the adjacent adjustable support unit 332 is taken as an example: First, a limiting recess 333 is machined at the first end of the bottom support unit 331, and the positioning portion 334 is connected to the positioning hole of the adjustable support unit 332. Then, one end of the adjustable support unit 332 with the positioning portion 334 is inserted from the second end of the bottom support unit 331, and finally the limiting recess 333 at the second end of the bottom support unit 331 is machined into shape.

[0056] Specifically, in order to facilitate processing and assembly, in addition to the bottom support unit 331 located at the bottom of the adjustable support member 330, each adjustable support unit 332 is designed to be provided with a limiting recess 333 at one end away from the positioning hole, that is, the limiting recess 333 is located at the upper end of each adjustable support unit 332, and the limiting of the lower end of each adjustable support unit 332 is achieved by the bottom support unit 331 connected thereto or the positioning portion 334 on the adjustable support unit 332.

[0057] The positioning protrusion on the positioning portion 334 extends from the positioning hole on the adjustable support unit 332 to the inside of the adjustable support unit 332 , and can limit the downward movement of the adjacent adjustable support unit 332 connected thereto.

[0058] 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.

[0059] The first rack 210 and the second rack 220 are spaced apart from each other along the depth direction of the washing cavity, and the second spray member 320 is located between the first rack 210 and the second rack 220 .

[0060] In addition to spraying and cleaning the items to be cleaned 400 on the first rack 210 together with the first spraying member 310, the second spraying member 320 can also clean the items to be cleaned 400 on the second rack 220 according to actual needs of users to improve cleaning efficiency.

[0061] 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.

[0062] 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.

[0063] The cleaning equipment has two layers of upper and lower support parts, which can clean 400 parts of different sizes in layers, with larger capacity and better cleaning effect; a spray part is correspondingly arranged at the bottom of each support part, which has high cleaning efficiency and reduces cleaning blind spots.

[0064] refer to Figure 8 , Fig. 9 In some embodiments of the present application, a penetrating connection hole 321 is formed on the second spray member 320, and the second spray member 320 includes at least two spray arms arranged at equal angles along the circumference of the connection hole 321, and each spray arm is formed with a spray channel, and the spray channel is connected with the water supply channel through the connection hole 321. A spray surface with the same direction is formed on each spray arm, and a plurality of spray holes 322 are arranged at intervals on the spray surface. A sealing cover portion 350 is detachably connected to the connection hole 321 for sealing the top of the connection hole 321.

[0065] Specifically, when the second rack 220 is connected to the washing inner cavity, the second 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 second spraying member 320 is configured with each spraying surface facing the first rack 210 , so as to wash the items 400 to be washed on the first rack 210 .

[0066] In other words, the second spray component 320 can be installed on both sides according to actual washing requirements, that is, its spraying surface can face the second rack 220 or the first rack 210. After the second 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 second spray component 320.

[0067] The above structure of the second 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 first spray member 310 and the second spray member 320 can also be used to clean the items to be cleaned 400 on the first shelf 210 and the second shelf 220 respectively, with a large washing capacity, stronger versatility, and simple and convenient operation.

[0068] Combination Figure 10-11 In some embodiments of the present application, the second spray component 320 is detachably connected to the top of the adjustable support component 330 through the adapter 340, a plurality of connecting parts 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 parts 342, the sealing part 350 is connected to the adapter 340, and the second spray component 320 is rotatably connected to the adapter 340.

[0069] 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 .

[0070] 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 adjustable support unit 332 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 adjustable support unit 332.

[0071] Specifically, a groove 246 is also provided on the second connecting end 341, and the grooves 246 are 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 adjustable support unit 332, 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 adjustable support unit 332 during the installation process, thereby improving the assembly efficiency.

[0072] In addition, in order to support and limit the second 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 second 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 second 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.

[0073] The second connection end 341 is a cylindrical structure with a closed top, and the communication portion 342 is formed on the circumference of the second connection end 341 .

[0074] 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.

[0075] 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 second spray part 320 is rotatably connected relative to the covering part 350.

[0076] The top of the cover portion 350 is also formed with a positioning outer edge 351 extending toward the circumferential side. The positioning outer edge 351 is located on the outer side of the second spray component 320 and is used to limit the second spray component 320.
