Detailed Description

Fig. 1 is a perspective view of a cleaning device according to some embodiments of the present invention in an extended state of the cartridge. Fig. 2 is a perspective view of a cleaning device according to further embodiments of the present invention in a folded state of the cartridge. As shown in fig. 1 and 2, embodiments of the present invention relate to a cleaning device 10, which includes: a base 12; and a cylinder 14 provided to the base 12 and foldable toward the base 12.

Therefore, the cleaning device 10 has the advantages of small volume, compact structure, portability, better satisfaction of the use requirements of users and the like.

The base 12 may be a generally square disk-shaped member. The base 12 may include an interior space 11 (see fig. 5) that may be used to house power, fluid, and electrical components 13 (see fig. 5) for proper operation of the cleaning device 10. The power, fluid, and electrical components 13 may include, for example, a motor pump, a water inlet elbow, a water outlet elbow, a battery pack, a circuit board module, a switch charging module, and the like. The base 12 may be provided with a charging port 15 and a switch 19.

The barrel 14 may include a thermoplastic elastomer (TPE), i.e., soft rubber, which may be manufactured through a two-shot injection molding process, so that the barrel 14 may be foldable, light-weight, and may have a soft touch of the TPE, which may provide a better user experience.

The two-shot molding process may refer to, for example, injection molding a rigid plastic such as polypropylene, polystyrene, acrylonitrile-butadiene-styrene copolymer, polycarbonate, or polyamide, and then coating a relatively thin thermoplastic elastomer on the surface of the rigid plastic by an injection molding process. Generally, in the secondary injection molding process, hard plastic is first injection molded into a hard plastic part in one set of mold a, and after the hard plastic part is cooled and taken down, the hard plastic part is placed into another set of mold B, and the TPE soft rubber is injection-molded and adhered to the hard plastic part in the mold B.

In the embodiment of the present application, the rigid plastic may be injection molded into the base 12 in one set of mold, and after the base 12 is cooled and removed, it is placed into another set of mold to injection mold the TPE soft plastic into the tubular member 14 adhered to the base 12.

The tubular member 14 is disposed on the base 12, so that the cleaning device 10 has a small size and a compact structure, and can better meet the use requirements of users in the case of limited space.

The folding of the cartridge 14 towards the base 12 further reduces the size of the cleaning device 10, makes the structure more compact and portable, and, in situations where space is limited, further reduces the size of the cleaning device 10 by folding the cartridge 14. When the cleaning device is stopped, the tubular member 14 can be folded to make the cleaning device 10 small in size and convenient to store. When desired, the barrel 14 can be extended for proper operation of the cleaning device 10. The cleaning device 10 is freely switchable between a collapsed position and an extended position of the bowl 14 to meet the needs of use.

In some embodiments, the cartridge 14 includes a top portion 16 and a body portion 18 connecting the top portion 16 to the base 12, the body portion 18 being foldable toward the base 12.

In this manner, folding of the cartridge 14 toward the base 12 may be facilitated.

The top portion 16 and the body portion 18 may each be hollow, generally annular. The top portion 16 may be provided with a logo 17 and a handle 23. The flag 17 may be a generally trapezoidal recess that may be used to add labels to the washing device 10. The label may be adhered to the label portion 17, for example, by a backing adhesive. Handle 23 may be a generally C-shaped strap-like member that may be used to facilitate easy removal of the position of the cleaning device 10. The handle 23 may be provided with a snap-fit portion 25 (see fig. 4), by which the top portion 16 may be connected. The engaging portion 25 may be, for example, a snap.

The main body 18 may be a two-shot molded soft gel that is foldable toward the base 12 based on the flexibility of the soft gel. When the cleaning device 10 is manufactured, the top 16 and the base 12 can be respectively formed by injection molding of rigid plastics in corresponding molds, then the formed top 16 and the base 12 are placed in the mold of the main body 18, and the main body 18 is formed by injection molding of soft glue and is adhered to the top 16 and the base 12 and connected with the top 16 and the base 12.

In operation, for example, the top portion 16 may be pressed to fold the body portion 18 inside the top portion 16, and at this time, the amount of deformation of the soft gel constituting the body portion 18 exceeds the rebound range thereof, so as to facilitate storage of the cleaning apparatus 10. Alternatively, the top portion 16 may be pulled to extend the folded main body portion 18, and the interior of the barrel 14 may be filled with water for operation of the cleaning device 10.

The main body portion 18 is provided with an indicating portion 31 which can be observed from the inside and outside thereof for indicating the level of the liquid inside the cylinder 14. For example, since the portion of the tube 14 filled with water is darker than the portion without water when viewed from the outside of the main body portion 18, the liquid level inside the tube 14 can be determined by the color brightness outside the main body portion 18. The liquid level inside the cylinder can be directly read from the indicating part 31 and the liquid level position inside the main body part 18. In use of the cleaning device 10, the liquid level inside the barrel 14 can be determined from a distance without going to the front of the cleaning device 10 by observing the indicator 31 from the outside of the main body 18; the user can directly determine the remaining amount of the liquid in the cylinder 14 by observing the indicator 31 from the inside of the body 18, and can determine whether the liquid in the cylinder 14 satisfies the need for subsequent operations.

Referring to fig. 2, in some embodiments, the cartridge 14 is folded to at least partially wrap around the base 12.

In this way, the cleaning device 10 can be advantageously compact.

The transverse dimension of the body portion 18 may decrease in a direction from the top portion 16 to the base 12, and the transverse dimensions of the top portion 16, the body portion 18, and the base 12 may decrease in sequence such that the cartridge 14 at least partially wraps around the base 12 after being folded.

In some embodiments, the cartridge 14 is at least partially received in the base 12 after folding.

In this way, the cleaning apparatus 10 can be advantageously compact.

In an embodiment not shown, the transverse dimension of the main body portion 18 may gradually increase in a direction from the top portion 16 to the base 12, and the transverse dimensions of the top portion 16, the main body portion 18 and the base 12 may sequentially increase, so that the barrel 14 is at least partially received in the base 12 after being folded.

In some embodiments, the base 12 includes a shoe 20, and the cartridge 14 is positioned on the shoe 20.

This can facilitate the simple construction of the cleaning device 10.

The shoe 20 may be a generally plate-like member corresponding in shape to the portion of the barrel 14 that contacts one another.

Base 12 may include a housing portion 21 (see fig. 5). The mounting 20 and the housing portion 21 may be provided with a first screw post 27 (see fig. 5) and a second screw post 29 (see fig. 5), respectively, the first screw post 27 and the second screw post 29 being connectable by, for example, screws such that the mounting 20 and the housing portion 21 in combination constitute a housing of the base 12.

FIG. 3 is a schematic top view of the cleaning apparatus of FIG. 2, except for the attachments. As shown in fig. 3, the shoe 20 may be provided with a filter screen 33 for filtering liquid inside the cartridge 14.
