DETAILED DESCRIPTION

[0030] Existing steam cleaning apparatus are usually equipped with a receiving box for accommodating accessories of the steam cleaning apparatus, including a water tank, a steam pipe, a steam handle, a steam nozzle, a steam brush, a circular brush and a detail nozzle, etc.

[0031] Since the water tank is also accommodated in the receiving box, the size of the water tank is limited. During use of the steam cleaning apparatus it is often necessary to stop working and to flush water into the water tank, and then to restart work again, thus a continuous operating time of the steam cleaning apparatus is relatively short.

[0032] Therefore, the present invention provides a steam cleaning apparatus. In the steam cleaning apparatus, on the one hand, a box cover is connected with a box body in an opening and closing manner, and serves as a cover of the box body, and on the other hand, the box cover also serves as a water tank of the steam cleaning apparatus for providing a water source for the steam cleaning apparatus. Since the box cover is arranged on the box body, the size of the water tank can be larger compared to being arranged in the receiving space provided by the box body, which can increase a volume of the water tank and increase a continuous operating time of the steam cleaning apparatus.

[0033] In order to make above purposes, features and advantages of the present invention more obvious and understandable, specific embodiments of the present invention will be explained in detail below in conjunction with the accompanying drawings

[0034] According to some embodiments, a steam cleaning apparatus includes: a box body having a receiving space; a box cover connected with the box body in an opening and closing manner, wherein the box cover is configured as a water tank for the steam cleaning apparatus; a steam control device arranged in the box body and outside the receiving space; and an accessory in fluid communication or connection with the steam control device and adapted to be accommodated in the receiving space.

[0035] The box body provides the receiving space, which allows the accessories to be accommodated in the receiving space, thus the storage of various accessories of the steam cleaning apparatus can be more tidy. In addition, as a cover of the box body, the box cover can convert the receiving space into a closed space, which can facilitate the movement of the steam cleaning apparatus. The box cover also serves as the water tank for providing a water source and is not limited by the receiving space, which prolongs the continuous operating time of the steam cleaning apparatus without an additional water tank and water tank cover, thereby reducing the overall weight of the steam cleaning apparatus.

[0036] FIG. 1 is a schematic view of a steam cleaning apparatus in a closed state according to an embodiment of the present invention, and FIG. 2 is a schematic view of the steam cleaning apparatus in an opened state according to an embodiment of the present invention;

[0037] Referring to FIGS. 1 and 2, the steam cleaning apparatus includes a box body 11, a box cover 12 and a steam control device. The box body 11 provides a receiving space, and the box cover 12 serves as an upper cover and a water tank of the box body 11. The box body 11 includes a lower cover 111 and a middle frame 112, and the receiving space is located in the middle frame 112. The steam control device is arranged in the lower cover 111 and outside the middle frame 112, and the receiving space can partially surround the steam control device. The box cover 12 is connected with the box body 11 in an opening and closing manner, that is, the box cover 12 can be in a closed position or in an open position relative to the box body 11. When the box cover 12 is in the closed position relative to the box body 11, the receiving space is closed and an overall storage is more tidy.

[0038] In some embodiments, the shape of the receiving space is not limited as long as it can accommodate various accessories.

[0039] In some embodiments, the box cover 12 has a hollow structure suitable for receiving water. The material of the box cover 12 may be polypropylene (PP) or high density polyethylene (HDPE). A thickness of a side wall of the box cover 12 ranges from 1 mm to 3mm. If the side wall of the box cover 12 is too thick, a volume of the water tank can be reduced. If the side wall of the box cover 12 is too thin, the box cover 12 cannot withstand enough pressure and is easy to crack.

[0040] In some embodiments, a shape of the box body 11 matches with a shape of the box cover 12. For example, both the box body 11 and the box cover 12 may have a rectangular shape. Certainly, the box body 11 and the box cover 12 may also have other shapes, which are not limited herein.

[0041] In some embodiments, there may be multiple ways of connecting the box cover to the box body in an opening and closing manner, which are not limited herein.

[0042] In some embodiments, the box cover 12 may be fixedly connected with the box body 11 (such as a hinge connection), that is, the box cover 12 may be non-removably connected with the box body 11. At this time, the box body 11 remains fixed and the box cover 12 can rotate around a connection axis between the box body 11 and the box cover 12.

[0043] In some embodiments, since the box cover 12 serves as the water tank, the box cover 12 may be removably connected with the box body 11, which can facilitate the removal of the box cover 12 from the box body 11 so that box cover 12 can be filled with water.

[0044] FIG. 3 is a schematic top view of a box cover according to an embodiment of the present disclosure, and FIG. 4 is a schematic bottom view of the box cover according to an embodiment of the present disclosure.

[0045] Referring to FIGS. 3 and 4, in some embodiments, the box cover 12 may be provided with a buckle fitting part 121, and the box body 11 may be provided with a buckle 113 (referring to FIG. 2).
