Description

FIELD OF THE INVENTION

The present invention relates to the field of indoor cleaning tools, and in particular to a sweeping and mopping integrated machine, by which floor sweeping and floor mopping may be completed simultaneously.

DESCRIPTION OF THE PRIOR ART

With the increasing improvement of people's quality of life, indoor cleaning becomes more and more important. In indoor cleaning, floor sweeping and floor mopping are common. At present, floor sweeping and floor mopping operations are performed separately. One needs to prepare tools for floor sweeping and floor mopping separately as well as operate floor sweeping and floor mopping separately at different time periods. There are a variety of cleaning tools prepared at home, occupying much space. Moreover, floor sweeping and floor mopping operations need to be performed separately, which is also a waste of time. In order to reduce the number of types of cleaning tools that one needs at home and to enable floor sweeping and floor mopping to be performed simultaneously for time saving, it is necessary to design a tool that can simultaneously sweep and mop the floor, so as to save space for a house and save the time taken by people in cleaning, thereby improving life efficiency.
Therefore, those skilled in the art devote themselves to developing a novel cleaning tool that may complete floor sweeping and floor mopping at the same time.

SUMMARY OF THE INVENTION

In view of the above drawbacks of the prior art, the technical problem to be resolved by the present invention is to provide a sweeping and mopping integrated machine.
To achieve the above object, the present invention provides a sweeping and mopping integrated machine, characterized by comprising a sweeping and mopping assembly, a collection assembly, a water spraying assembly, and a handle, wherein the water spraying assembly is provided on the handle or the sweeping and mopping assembly and comprises a water storage assembly and a nozzle assembly; the water spraying assembly is configured to spray, through the nozzle assembly, water or a cleaning liquid in the water storage assembly onto a working surface to be swept and mopped; the sweeping and mopping assembly comprises a motor and a drum-type working portion which is rotatable when driven by the motor; and the sweeping and mopping assembly is configured to sweep and mop the working surface and bring garbage and liquid on the working surface into the collection assembly through the rotation of the drum-type working portion.
Further, the nozzle assembly is a nozzle which is provided as a liquid outlet.
Further, the water spraying assembly comprises a manual pump or an electric pump.
Further, the sweeping and mopping assembly comprises a battery, and the motor is powered by the battery.
Further, the material of the drum-type working portion comprises cloth, sponge, felt, collodion, or fiber.
Further, the drum-type working portion is detachable.
Further, the handle comprises a gripping bend, wherein a switch of the water spraying assembly is provided at the gripping bend, and the switch is of a mechanical type or an electronic type.
Further, the sweeping and mopping integrated machine further comprises a control switch, which is provided on the sweeping and mopping assembly or the handle.
Preferably, the control switch is provided on a handle assembly.
Further, the sweeping and mopping assembly comprises an electronic control assembly.
Further, the collection assembly is detachable.
Compared with the prior art, in the present invention, it is possible to spray water through a nozzle onto a floor to be mopped, which is conductive to wet floor mopping, and with the high-speed rotation of a rolling brush, garbage may be swept into a garbage box, and excess water and garbage may also be swept into the garbage box simultaneously, such that floor sweeping and floor mopping are performed simultaneously, thereby resolving the problem that an existing ordinary mop cannot sweep garbage and an ordinary sweeper cannot mop the floor once and for all.
The drum-type working portion of the present invention may rotate at a high speed when driven by a motor, such that when a “mopping” effect is produced due to friction on a working surface such as a floor or a window, solid waste and liquid may be brought and drawn into the collection assembly with the rotational movement of the working portion and a negative pressure formed thereby, that is, a “sweeping” effect. Meanwhile, high-speed rotation may also “spin” the liquid absorbed by the working portion itself into the collection assembly, that is, a spin-drying function, such that the working portion may continuously absorb the liquid on the working surface.
Existing dust collectors cannot perform wet floor mopping, are highly noisy, and are expensive and inconvenient to use without a power cord. Sweeping robots on the market cannot mop the floor in a wet manner, among which, very few can mop the floor in a wet manner but have secondary pollution and high price. Whereas the sweeping and mopping integrated machine of the present invention may be handheld and convenient to operate, without secondary pollution when performing wet floor mopping, and the price is low.
The concepts, specific structures and produced technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the objects, features, and effects of the present invention.

The handle upper connecting rod is located on the proximal end and the handle lower connecting rod is located on the distal end. Specifically, the sweeping and mopping assembly 1 is connected to the water spraying assembly 2, which is connected to the handle lower connecting rod. The sweeping and mopping assembly 1, the water spraying assembly 2, the handle lower connecting rod, and the handle upper connecting rod are sequentially connected from the distal end to the proximal end of the sweeping and mopping integrated machine.
The handle assembly 4 is connected to the handle upper connecting rod. The handle lower connecting rod is connected to the handle upper connecting rod on a side towards the proximal end through the handle connecting piece and to the water spraying assembly 2 on a side close to the distal end. The water spraying assembly 2 is connected to the sweeping and mopping assembly 1 through a connecting piece. The water spraying assembly 2 may be flexibly rotated relative to the sweeping and mopping assembly 1. The user may adjust the angle between the handle and the sweeping and mopping assembly 1 by rotating the handle so as to ensure quick and easy adjustment to the most suitable and comfortable position when sweeping and mopping operations are performed. Connection between the water spraying assembly 2 and the handle lower connecting rod is a fixed connection. In a process of using the sweeping and mopping integrated machine, the water spraying assembly 2 is responsible for spraying water, which is atomized by the nozzle and falls on the floor evenly so as to keep the floor moist, while the sweeping and mopping assembly 1 is responsible for completing the floor mopping and floor sweeping operations, such that wet floor mopping and floor sweeping are completed simultaneously. The water spraying assembly 2 maintains a certain distance from the sweeping and mopping assembly 1. The sweeping and mopping assembly 1, when in operation, is attached to the floor, and the water spraying assembly 2 is fixed on the handle lower connecting rod and at a certain distance away from the floor so as to ensure that the water sprayed by the spray assembly 2 may be sprayed onto the floor instead of falling onto a surface of the sweeping and mopping assembly 1. The handle upper connecting rod is connected to the handle lower connecting rod on the side towards the distal end through the handle connecting piece and to the handle assembly 4 on the side close to the proximal end.
As shown in FIG. 2, the water spraying assembly 2 comprises a water storage assembly 201 (as shown in FIG. 3) and a nozzle assembly 202 (as shown in FIG. 4).
