Detailed Description

When there are various types of dirt adhered to the surface to be cleaned, the cleaning work cannot be fully performed only with the dry vacuum cleaner. Thus, users are often required to use multifunctional surface cleaning devices to clean their target area.

Referring to fig. 1-2, a surface cleaning apparatus 100 in accordance with the teachings of the present invention is shown. As shown in this figure, the surface cleaning apparatus 100 may comprise an upright vacuum cleaner 10 and a removable device 20. Wherein the upright type vacuum cleaner 10 includes a cleaning base 12 adapted to be moved on a surface to be cleaned, and a cleaner main body 11 rotatably connected to the cleaning base 12 at a lower portion thereof. The upper part of the main dust collector 11 is provided with a handle 112, and the middle part is provided with a gas-solid separation box 113 and a vacuum motor 114. The vacuum motor 114 can form a flowing air current into the gas-solid separation tank 113 from the lower portion of the dust suction main body 11. In some embodiments, handle 112 may have an adjustable length to allow a user to adjust the height of the cleaning device. In this example, the removable device 20 is removably mounted to the rear of the cleaning base 12.

Referring to fig. 3, the cleaning base 12 includes an adapter 121 having a housing 120 and an upper rear portion 1201 mounted to the housing 120. The front lower portion 1202 of the housing 120 is provided with a cleaning opening 122 facing the surface to be cleaned, and the interior of the housing 120 defines a roller brush chamber (not shown) above the cleaning opening 122. The rolling brush chamber is provided with a rolling brush 123 (see fig. 2) which can rotate, and the lower end part of the rolling brush 123 extends downwards from the dust suction opening 122 and can contact the ground to be cleaned during operation. A dust suction passage (not shown) is provided inside the housing 120 to communicate the rolling brush chamber with the adaptor 121. The rear lower portion 1203 of the housing 120 is also provided with a pair of rear wheels 124. The rear portion of the housing 120 is supported on the floor surface to be cleaned by the pair of rear wheels 124 and is movable along the floor surface to be cleaned.

Thus, an airflow path is formed in the upright vacuum cleaner 10 to communicate the suction port 122, the suction passage, the gas-solid separation tank 113, and the vacuum motor 114. After the dust-containing air flow is sucked into the cleaning base 12 through the dust suction opening 122, the dust-containing air flow upwards flows into the gas-solid separation box 113 through the adapter 12, the solid garbage in the dust-containing air flow is remained in the gas-solid separation box 113, and the clean air flows into the vacuum motor 114 and then escapes to the outside of the device 10.

Referring to fig. 4-5, the removable device 20 includes a base plate 21, a retaining mechanism 22 disposed on the base plate 21, and a wet-type wiping sheet 23 secured to the base plate 21 by the retaining mechanism 22. The base plate 21 has an upper surface 211 and a lower surface 212 opposite the upper surface 211. Lower surface 212 is a generally planar surface. The holding mechanism 22 includes a clip 221 that can be opened and closed, and by means of the clip 221, the wet wiping blade 23 can be held firmly on the base plate 21. When the wet wipe sheet 23 is fixed to the chassis 21, most of the sheet body 231 of the wet wipe sheet 23 covers the lower side of the lower surface 212, and the front edge 232 and the rear edge 233 of the wet wipe sheet 23 are folded toward the middle and held on the upper side of the upper surface 211 by the clips 221. The user can optionally add or replace wet wipe blade 23 by manipulating the openable and closable clip 221 as desired.

The wet wipe sheet 23 of the present example is preferably manufactured from disposable consumables, i.e., the wet wipe sheet may be removed and discarded by a user after one or more wiping jobs have been performed. The wet wiping sheet 23 of this example is a wiping member pre-impregnated with a cleaning solution, which enables wet wiping of the floor. In other embodiments, dry wipes, or other non-disposable, reusable wipe configurations may be used.

As shown in fig. 6, the bottom panel 21 has a front side edge portion 2111 and a rear side edge portion 2112, and the front-rear distance between the front side edge portion 2111 and the rear side edge portion 2112 defines the front-rear width D of the bottom panel 21. A pair of force application areas 213 are provided in the middle of the upper surface 211 of the base plate 21, the distance D1 between the front side edge 2131 and the front side edge portion 2111 of the force application areas 213 is set to 1/4D or more, and the distance D2 between the rear side edge 2132 and the rear side edge portion 2112 of the force application areas 213 is set to 1/4D or more. The force application zone 213 is configured to have a concave profile toward the lower side for engaging the lower portion of the pair of rear wheels 124. In order to prevent the rear wheels 124 located in the force application areas 213 from sliding forward out of the force application areas 213 during the cleaning base 12 is pushed forward, a pair of force application areas 213 have a stopper boss 214 at the front thereof, respectively.

When the removable device 20 is attached to the rear of the cleaning base 12, the downward force transmitted to the removable device 20 can always be kept as much as possible in the middle position of the removable device 20, so that the wet wiping sheet 23 at the lower part of the removable device 20 can always be attached to the surface to be cleaned, thereby keeping the cleaning efficiency high.

As shown in fig. 5-6, the upper surface 211 of the bottom plate 21 is further provided with a suction area 215; to configure the attraction area 215, the bottom wall of the housing 120 is provided with an attraction area 125 (shown in fig. 2) corresponding to the first attraction area 215, and the attraction area 125 will be located between the pair of rear wheels 124. In the attraction sections 215 and 125, a magnetic element is disposed on one attraction section, and a magnetic element attracted and fixed by the magnetic element is disposed on the other attraction section.

As shown in fig. 7, when the removable device 20 is mounted at the rear of the cleaning chassis 12, the pair of rear wheels 124 are positioned in the force application zone 213 so that the force applied by the user to the upright vacuum cleaner 10 via the handle 112 is transmitted down to the removable device 20 by the pair of rear wheels 124, thereby enabling the wet wipe 23 on the removable device 20 to be frictionally wiped across the surface to be cleaned.

In this example, the lower end of the roller brush 123 and the lower ends of the pair of rear wheels 124 define a base M. The removable device 20 is configured such that when the removable device 20 is mounted to the rear of the cleaning base 12, the lower end of the roller brush 123 defines a plane P with the lower surface of the wet wiping blade 23, the plane P being at an angle C of 2-8 ° to the base M. By the angle, the dust suction opening 122 at the front lower part of the housing 120 can be kept as close to the ground as possible in a stable suction state after the removable device 20 is installed at the rear part of the cleaning base 12.

As shown in fig. 8, the main vacuum cleaner 11 in this embodiment is also removable from the cleaning base 1. The cleaner main body 11, which is removed from the cleaning chassis 1, has a lower portion that can be engaged with an accessory such as a dust suction accessory 30 to enable the cleaner main body 11 to be used as a hand cleaner.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
