Description

A multi-purpose cleaning device

technical field

The invention relates to a cleaning device with functions of absorbing water and dust, in particular to the structural improvement of the suction nozzle of the cleaning device, and belongs to the technical field of dust removal and cleaning appliances.

Background technique

At present, cleaning devices such as pneumatic vacuum cleaning brushes are not uncommon. The search found that US patents such as US5088149 and US6513190 disclosed related technologies respectively. However, this kind of product has no separate water suction channel and sewage suction nozzle because the dirty air recovery channel overlaps with the driving air channel of the wind impeller, so after long-term use, the sewage and solution flowing through the impeller will cause erosion to the bearing and transmission device damage. In fact, the air inlet of the above-mentioned pneumatic cleaning brush can only remove dust but cannot be used to remove sewage.

In addition, the search also found that the patent Nos. US6185781, US6134746 and other US patents disclose the structure of the wind-driven water-absorbing cleaning brush. Although the sewage recovery channel of this type of patented product is separated from the driving air channel of the wind impeller, and has a separate water suction channel and sewage suction nozzle, in order to ensure the function of the suction nozzle of this type of product, its size is limited, resulting in the suction nozzle. The air flow and specifications are insufficient for vacuuming. As a result, the air inlet of this type of pneumatic cleaning brush can only clean sewage but is difficult to use for dust removal.

Contents of the invention

The object of the present invention is to propose a multi-purpose cleaning device capable of removing dust and sewage in view of the above shortcomings of the prior art.

In order to achieve the above object, one end of the housing of the multi-purpose cleaning device of the present invention has an outlet, an air-flow driven impeller and a driven roller brush are installed inside, and a suction port is opened below; the improvement is that: the housing is equipped with a The impeller is isolated and communicated with the sewage recovery channel; the housing is also provided with an air inlet, and a suction nozzle assembly with a water inlet and a water outlet is installed; the suction nozzle assembly has a first position and a second position; When in the first position, the suction nozzle assembly closes the inlet, and the suction port communicates with the outlet through the impeller; when in the second position, the suction nozzle assembly closes the passage between the suction inlet and the impeller, and the inlet The air port is opened and communicated with the outlet through the impeller, and at the same time, the water outlet of the suction nozzle assembly communicates with the sewage recovery channel.

In this way, the device of the present invention can be in two working states suitable for dust suction and water suction respectively by simply switching the suction nozzle assembly:

When it is in the dust suction working state corresponding to the first position of the suction nozzle assembly, the dusty air is discharged from the outlet through the suction port through the impeller, and the dust suction operation is successfully completed.

When it is in the working state of absorbing water corresponding to the second position of the suction nozzle assembly, the air is discharged from the outlet through the air inlet through the impeller, and a negative pressure is generated through the recovery channel, so that the sewage can be sucked by the water inlet of the suction nozzle assembly, and passed through the water outlet. Sewage recovery channel, discharged by the outlet, to achieve the required water suction operation.

In the above working process, since the present invention has separate channels for water absorption and sewage recovery, it can avoid the erosion of sewage on the impeller and the transmission device. At the same time, due to the rational setting of the suction nozzle assembly, the air flow of the suction port is not affected, and the ideal dust collection effect can be maintained. It can be seen that the present invention solves the problem that the existing air-driven dust-absorbing cleaning brush cannot absorb water, and the air-operated water-absorbing cleaning brush cannot be used for dust absorption, and has significant substantive features and outstanding progress.

Detailed ways

Embodiment one

This embodiment is a multi-purpose cleaning brush for vacuum cleaners, the specific structure is shown in Figure 1, the upper and lower parts of the middle frame 1 are respectively buckled to cover the front cover 2 and the bottom cover 3, forming a complete machine case.

The rear end of the casing forms a tubular outlet, and there is a suction port below. The interior is divided into upper and lower chambers. The upper chamber is equipped with an airflow-driven impeller assembly 6, and the lower chamber is equipped with a roller brush assembly 7 connected to the impeller assembly through a belt 8. There is an opening between the upper and lower chambers. One side of the impeller in the casing is provided with a sewage recovery channel 15 isolated from the impeller. One end of the sewage recovery channel 15 communicates with the outlet, and the other end faces the water inlet 14 of the middle frame.

The front cover 2 of the housing is provided with an air inlet 11 communicating with the upper cavity, and the front end of the housing is equipped with a blade-shaped suction nozzle 4 through a mobile pair formed by an interfitting chute 17 and a nozzle slide rail 18 . There is an extended nozzle water inlet 12 at the lower end of the nozzle, and a nozzle outlet 13 is opened on the inner side corresponding to the water inlet 14 of the middle frame (see Figure 2). 5.

When the suction nozzle 4 and the switching valve 15 are brought to the upper limit position defined by the limit device 16 on the suction nozzle through operation (see Figure 5 and Figure 8), the air inlet at the front end of the housing is closed by the upper end of the suction nozzle, and The opening between the upper and lower chambers in the housing is opened, and the suction port communicates with the outlet from the lower brush chamber through the opening to the upper impeller chamber. After the impeller assembly 6 is activated by the air flow, it drives the lower roller brush assembly 7 through transmission, so that the dust under the suction port can be brushed and sucked away. Now the cleaning brush of the present embodiment is in the working state of cleaning and vacuuming.

When the suction nozzle 4 and the switching valve 15 are lowered to the lower limit position defined by the suction nozzle limiter 16 through operation (see Figure 4 and Figure 7), the air inlet at the front end of the housing is opened, and the upper and lower The opening between the two cavities is closed by the switching valve, the air inlet communicates with the outlet through the impeller, and the water outlet of the suction nozzle assembly communicates with the sewage recovery channel at the same time. The impeller assembly 6 is activated by the air flow. The air is inhaled by the air inlet and discharged from the outlet, and the sewage recovery channel is subjected to suction negative pressure, so that the sewage can be sucked by the water inlet of the suction nozzle assembly, and discharged from the outlet through the sewage recovery channel isolated from the impeller. At this moment, the cleaning brush of this embodiment is in the working state of removing sewage.

The pneumatic multi-purpose cleaning brush for dust suction and water absorption of this embodiment properly solves the problem that ordinary wind-driven dust-absorption cleaning brushes cannot absorb water, and the wind-driven water-absorption cleaning brush cannot be used for dust collection, so that ordinary vacuum cleaners only need to be equipped with this one wind cleaning brush. The multi-purpose cleaning brush for vacuuming and absorbing water can complete the above operations, so it has wider applicability.

In addition to the above-mentioned embodiments, the present invention can also have other implementations. For example, the upper and lower limit devices can be various concave-convex blocking structures; for another example, various other switching structures can be used to replace the switching valve; and so on. Therefore, all technical solutions formed by those skilled in the art by referring to the present invention and adopting equivalent replacements or equivalent transformations all fall within the scope of protection required by the present invention.
