[0063] The adjustable support 330 is formed with a water supply channel, and comprises a bottom support unit 331 and at least one adjustable support unit 332. The bottom support unit 331 and the adjustable support unit 332 are both tubular structures, and are movably connected between each other. The bottom of the bottom support unit 331 is configured to be connected to a water supply assembly.

[0064] The spraying member is rotatably connected to one end of the adjustable support unit 332 away from the bottom support unit 331.

[0065] The rotation of the spraying member can be driven by a driving structure, or the spraying holes 322 thereon can be designed to be inclined. In a washing state, the spraying member is rotated under the reaction of the washing water output from the spraying holes 322, so as to uniformly spray the washing water in the washing inner cavity and clean the objects to be cleaned.

[0066] In some embodiments of the present application, the number of the adjustable support units 332 can be designed to be one or more than one according to actual design requirements.

[0067] When the number of the adjustable support units 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 relative to the bottom support unit 331 within a certain range.

[0068] Specifically, the two ends of the bottom support unit 331 are respectively formed with limiting recesses 333 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 above it. The outer wall of one end of the adjustable support unit 332 extending into the bottom support unit 331 is provided with a positioning portion 334.

One end of each of the adjustable support units 332 extending into the adjacent adjustable support units 332 is provided with a positioning portion 334.

[0071] The inner diameter size of the limiting recess 333 is matched with the outer wall size of the adjustable support unit 332 connected above the limiting recess 333, and the limiting recess 333 and the adjustable support unit 332 connected therewith form a close connection to ensure the sealing property and avoid water leakage.

[0072] 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 part 334 connected thereon moves synchronously until the positioning part 334 contacts with the limiting recess 333, and the adjustable support unit 332 is adjusted to the position.

[0073] Specifically, the lower end of the adjustable support unit 332 is provided with at least two positioning holes arranged at equal angles along the circumferential direction, and the positioning part 334 is specifically a positioning arc piece, and the positioning arc piece is provided with a positioning protrusion, and the positioning part 334 is connected to the outer wall of the adjustable support unit 332 through the positioning protrusion.

[0074] 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.

[0075] Firstly, a limiting recess 333 is formed at the first end of the bottom support unit 331, the positioning part 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 part 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 formed.

[0076] Specifically, in order to facilitate processing and assembly, in addition to the bottom support unit 331 located at the bottom of the adjustable support unit 330, the end of each adjustable support unit 332 away from the positioning hole is provided with a limiting recess 333, that is, the limiting recess 333 is located at the upper end of each adjustable support unit 332, and the limiting at the lower end of each adjustable support unit 332 is realized through the positioning part 334 of the bottom support unit 331 or the adjustable support unit 332 connected therewith.

[0077] The positioning protrusion on the positioning part 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 thereabove.

[0078] Reference Figures 1-3 The application also provides a cleaning device, which comprises an outer shell 100, a base 110, a shelf assembly 200, and the adjustable lifting and spraying structure.

[0079] The shelf assembly 200 at least comprises a first shelf 210 arranged at the bottom of the washing inner cavity and used for supporting the cleaning object 400.

[0086] The first spraying member 310 is internally formed with spraying holes 322 facing the first shelf 210. The first spraying member 310 outputs washing water upward, and cleans the to-be-cleaned member 400.

[0087] The first spraying member 310 can be arranged in a fixed structure, or can be rotatably connected below the first shelf 210.

[0088] The spraying holes 322 on the first spraying member 310 are arranged in the same inclined direction. In a washing state, under the reaction of the washing water output from the spraying holes 322, the first spraying member 310 rotates, and uniformly sprays the washing water in the washing inner cavity, so as to clean the to-be-cleaned member placed on the first shelf 210.

[0089] For the convenience of understanding, the spraying member involved in the liftable spraying structure is defined as a second spraying member 320.

[0090] The second spraying member 320 is connected above the first shelf 210 through an adjustable support 330. The height of the adjustable support 330 is adjustable, and the height of the second spraying member 320 is adjusted, so as to adapt to the position of the to-be-cleaned member 400 in the washing inner cavity, and improve the cleaning effect.

[0091] Specifically, when the height of the item to be cleaned 400 on the first shelf 210 is low, the height of the adjustable support 330 is lowered, and the second sprayer 320 is above the item to be cleaned 400 and moves towards the item to be cleaned 400 to increase the impact force of the washing water sprayed from the second sprayer 320 on the item to be cleaned 400.

[0092] When the height of the item to be cleaned 400 on the first shelf 210 is high, such as a baby bottle, the height of the adjustable support 330 is adjusted to match the item to be cleaned 400.

[0093] In some embodiments, the adjustable support 330 is vertically arranged and includes 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 below the bottom support unit 331, and the second spray member 320 is rotatably connected to the topmost adjustable support unit 332.

[0094] To facilitate 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. The middle of the first shelf 210 also has a through hole that communicates with the inner cavity of the bottom support unit 331. The first spraying component 310 is connected to the bottom support unit 331 through the through hole.

[0096] The first shelf 210 and the second shelf 220 are spaced apart along the depth direction of the washing cavity, and the second spray element 320 is located between the first shelf 210 and the second shelf 220.

[0097] In addition to spraying and cleaning the parts 400 to be cleaned on the first shelf 210 together with the first spraying component 310, the second spraying component 320 can also clean the parts 400 to be cleaned on the second shelf 220 according to the user's actual needs, so as to improve cleaning efficiency.

[0098] The second shelf 220 is detachably connected to the washing cavity to facilitate the placement and removal of the item 400 to be washed on the first shelf 210. Specifically, an inner support protrusion extending into the washing cavity is formed on the side wall of the washing cavity, and the second shelf 220 is supported on the inner support protrusion.

[0099] Of course, the second shelf 220 can also be connected by other detachable connection such as buckle, and the specific connection is not the design focus of the present application, which will not be described here.
