DETAILED DESCRIPTION

[0059] FIG. 1 is a schematic perspective view of a cleaning apparatus according to an embodiment of the present disclosure, wherein a tubular member is in an unfolded state, and FIG. 2 is another schematic perspective view of the cleaning apparatus in FIG. 1 , wherein a tubular member is in a folded state. As shown in FIGS.1 and 2, the embodiments of the present disclosure provide a cleaning apparatus 10. The cleaning apparatus 10 includes a base 12 and a tubular member 14. The tubular member 14 is arranged on the base 12 and can be folded towards the base 12.

[0060] In this way, the cleaning apparatus 10 can have small size, compact structure and convenient portability, and thus can better meet user needs.

[0061] The base 12 may be a roughly square plate-shaped component. The base 12 may include an internal space 11 (see FIG. 5) for accommodating power, fluid and electrical components 13 (see FIG.5) to ensure normal operation of the cleaning apparatus 10. The power, fluid and electrical components 13 may include, for example, motor pumps, inlet elbows, outlet elbows, battery packs, circuit board modules and switch charging modules. The base 12 may be provided with a charging port 15 and a switch 19.

[0062] The tubular member 14 may include thermoplastic elastomer (TPE), i.e. soft plastic, which can be made by a secondary injection molding process, so that the tubular member 14 can be foldable, lightweight, and have soft touch of TPE, thereby providing users with a better user experience.

[0063] The secondary injection molding process can refer to, for example, first injecting a hard plastic such as polypropylene, polystyrene, acrylonitrile butadiene styrene copolymer, polycarbonate, polyamide, etc., and then coating a relatively thin layer of thermoplastic elastomer on a surface of the hard plastic through the injection molding process. Usually, the secondary injection molding process can first inject the hard plastic into a hard plastic component in a mold A. After the hard plastic component cools down, the hard plastic component is removed and placed into another mold B, and then a TPE soft plastic is injected and bonded to the hard plastic component in the mold B.

[0064] In some embodiments, the hard plastic may be first injected in a mold to form the base 12. After the base 12 cools down, the base 12 is removed and placed into another mold, and then the TPE soft plastic is injected and bonded to the base 12 to form the tubular member 14.

[0065] The tubular member 14 is arranged on the base 12, so that the cleaning apparatus 10 can have small size and compact structure, and thus can better meet user needs in a limited space.

[0066] The tubular member 14 can be folded towards the base 12 so that the cleaning apparatus 10 can have small size, compact structure and convenient portability. Moreover, in the limited space, the size of the cleaning apparatus 10 can be further reduced by folding the tubular member 14. In a non-working state, the tubular member 14 can be folded to make the cleaning apparatus 10 compact and easy to store. In a working state, the tubular member 14 can be extended to ensure the normal operation of the cleaning apparatus 10. The cleaning apparatus 10 can be freely switched between the folded state and the unfolded state of the tubular member 14 to meet the user needs.

[0067] In some embodiments, the tubular member 14 includes a top 16 and a main body 18 for connecting the top 16 and the base 12, and the main body 18 can be folded towards the base 12.

[0068] In this way, it is beneficial to easily fold the tubular member 14 towards the base 12.

[0069] The top 16 and the main body 18 may each have a roughly hollow circular shape. The top 16 may have a label portion 17 and a handle 23. The label portion 17 may be a roughly trapezoidal concave par, and a label may be added to the cleaning apparatus 10. For example, the label may be attached to the label portion 17 through a back adhesive. The handle 23 may be a roughly C-shaped strip component, which can be used to conveniently move the cleaning apparatus 10. The handle 23 may have a clamping portion 25 (see FIG. 4), and the handle 23 may be connected to the top 16 through the clamping portion 25. The clamping portion 25 may be, for example, a buckle.

[0070] The main body 18 can be a soft plastic formed by a secondary injection molding process, and can be folded towards the base 12 based on the flexibility of the soft plastic. When manufacturing the cleaning apparatus 10, the top 16 and the base 12 can be respectively molded by hard plastic through injection molding in corresponding molds, and then the molded top 16 and the base 12 can be placed in the mold of the main body 18. The soft plastic is injected to form the main body 18 and bonded to the top 16 and the base 12 to be connected to the top 16 and the base 12.

[0071] In operation, for example, the top 16 can be pressed to fold the main body 18 to an inner side of the top 16. At this time, the deformation of the soft plastic forming the main body 18 exceeds its rebound range, in order to facilitate the storage of the cleaning apparatus 10. Alternatively, the top 16 can be pulled to extend the folded main body 18, and at this time, the tubular member 14 can be filled with water to facilitate the operation of the cleaning apparatus 10.

[0072] The main body 18 is provided with an indicating portion 31 that can be observed from both inner and outer sides to indicate a liquid level in the tubular member 14. For example, when viewed from the outer side of the main body 18, a portion filled with water in the tubular member 14 is darker in color than a portion without water. Therefore, the liquid level in the tubular member 14 can be determined by a color brightness on the outer side of the main body 18. On the inner side of the main body 18, the liquid level in the tubular member can be directly read based on the indicating portion 31 and a position of the liquid level. In the use of the cleaning apparatus 10, the indicating portion 31 can be observed from the outer side of the main body 18 to determine the liquid level in the tubular member 14 from a distance, without having to walk near the cleaning apparatus 10. Observing the indicating portion 31 from the inner side of the main body 18 can directly determine residual liquid in the tubular member 14, so that users can determine whether the liquid in the tubular member 14 meets the needs of subsequent work.

[0073] Referring to FIG. 2, in some embodiments, the tubular member 14 at least partially surrounds the base 12 after being folded.

[0074] In this way, it is beneficial to obtain a compact structure of the cleaning apparatus 10.

[0075] A lateral dimension of the main body 18 can gradually decrease in a direction from the top 16 to the base 12, and lateral dimensions of the top 16, the main body 18, and the base 12 can be sequentially reduced, so that the tubular member 14 can at least partially surrounds the base 12 after being folded. [0076] In some embodiments, the tubular member 14 is at least partially accommodated in the base 12 after being folded.

[0077] In this way, it is beneficial to obtain a compact structure of the cleaning apparatus 10.

[0078] In some embodiments not shown, the lateral dimension of the main body 18 can gradually increase in the direction from the top 16 to the base 12, and the lateral dimensions of the top 16, the main body 18 and the base 12 can sequentially increase, so that the tubular member 14 can be at least partially accommodated in the base 12 after being folded.

[0079] In some embodiments, the base 12 includes a base support 20, and the tubular member 14 is arranged on the base support 20.

[0080] In this way, it is beneficial to obtain a simple structure of the cleaning apparatus 10.

[0081] The bottom support 20 can be a roughly plate-shaped component corresponding to a shape of a portion in contact with the tubular member 14.

[0082] The base 12 may include a housing portion 21 (see FIG. 5). The base 20 and the housing portion 21 can be respectively provided with a first screw post 27 (see FIG. 5) and a second screw post 29 (see FIG. 5). The first screw post 27 and the second screw post 29 can be connected by a screw to combine the base 20 and the housing portion 21 to form a shell of the base 12.
