TECHNICAL FIELD
The present invention relates to a cleaning tool in daily life, and in particular, to an environment-protection energy-saving barrel.
BACKGROUND
For a long time, when mopping floors with a mop barrel, only the water for cleaning the mop at the first time is clean as long as the water in the barrel is unchanged; thereafter, the more the mop is washed, the dirtier the floor is. Every time the water in the original barrel is used for washing, and it is finally found that the mop is cleaned with the sewage all the time when mopping the floor. It apparently seems that the floor has been mopped, but actually, the floor is not clean at all. This is because the water for mopping the floor is unchanged. The water has a lot of dust, sand and other dirt due to cleaning the mop for many times.
Chinese patent public document 1 (publication No. 201445499U) discloses a mop barrel, which consists of a barrel body and a dewatering basket, wherein the interior of the barrel body is connected with the dewatering basket, the dewatering basket is connected with a pedal linkage device through a rotation shaft, the edge at the upper part of the barrel body is connected with a lifting handle through a lifting handle shaft, and the lifting handle is connected in a sliding manner with the barrel body in a sliding groove through a supporting shaft and a sliding shaft at one end of a supporting rod; the upper part of the dewatering basket is connected with two semicircular fasteners, i.e. a left fastener and a right fastener, the left fastener and the right fastener are connected with the dewatering basket through a rotating shaft, and the two fasteners can rotate upwards to be combined and connected and rotate downwards to be respectively superposed with the basket opening of the dewatering basket; and the pedal linkage device is made up in a manner that a foot board and a shaft arm are in rotational connection through an arm shaft, and the shaft arm is connected in a sliding manner with a rectangular sliding tooth block through a spring in a sliding fixing seat, so as to drive a gearwheel, a medium gear, and a pinion wheel to rotate in sequence.
The dewatering basket in the above-mentioned public document 1 plays a main role of dewatering and cleaning dirt, but the structure thereof is very complicated, and long-term use is likely to cause damage and loss of the link mechanism, which is very difficult to maintain for a person not skilled in the art, and the manufacturing cost is higher, which is unacceptable for ordinary people.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
As shown in FIG. 1, an environment-protection energy-saving barrel according to an embodiment of the present invention includes a barrel body, wherein the barrel body (1) includes three parts, i.e., an outer barrel (2), a middle barrel (3) and an inner barrel (4). The inner barrel (4) is communicated with the middle barrel (3) through a plurality of through holes in the wall between the inner barrel and the middle barrel. The bottom of the middle barrel is provided with a water inlet pipeline (5). The water inlet pipeline is communicated with the bottom of the outer barrel for storing water. One end of the outer barrel is provided with a water inlet quality controller (6) for the water inlet pipeline. The water inlet quantity controller (6) consists of a floater (6.1), a water quantity regulating rod (6.2) and a water outlet valve switch (6.3).
The floater (6.1) is arranged at one end of the water quantity regulating rod (6.2), and the water outlet valve switch (6.3) arranged at the other end thereof is located at the end port portion of the water inlet pipeline (5). The water quantity regulating rod passes through the wall between the middle barrel and the outer barrel. The floater (6.1) is arranged in the middle barrel (3) and the water outlet valve switch (6.3) is arranged in the outer barrel.
The bottom of the barrel body (1) is provided with a filtering barrel (9). The filtering barrel is internally provided with a plurality of clapboards (11) for depositing and filtering.
The bottom of the inner barrel is provided with a drain valve (8). The drain valve (8) is communicated with the filtering barrel. The bottom of the inner barrel is further provided with a dewatering pressing plate (7). The dewatering pressing plate (7) is connected with the drain valve (8) into a whole to drain the whole sewage into the filtering barrel, and thus keeping the water in the water barrel clean. The bottom of the inner barrel is provided with a reset spring (13). The other end of the reset spring comes into contact with the lower end of the dewatering pressing plate (7).
A cover plate (12) is fixed at the outer edge of the dewatering pressing plate (7). The end portion of the cover plate (12) is made into a water inlet valve (10). The water inlet valve (10) is located above the end port portion of the water inlet pipeline (5) in the middle barrel and remains a certain gap from the end port.
The operating principle of the environment-protection energy-saving barrel in the above-mentioned embodiment is as follows: the environment-protection energy-saving barrel is designed to consist of three parts, namely an outer barrel, a middle barrel and an inner barrel which form into a whole, wherein as a plurality holes are opened in the wall between the middle barrel and the inner barrel, the water in the middle barrel is communicated with the water in the inner barrel. The water source accesses into the middle barrel from the outer barrel via the water inlet pipeline (5) between the outer barrel and the middle barrel. A mop is cleaned in the inner barrel each time, and the water in the middle barrel is separated from the water in the outer barrel via the wall, so the sewage caused by cleaning the mop fails to reflow into the outer barrel.
When needing to dewater the mop, the user just only hold the handle of the mop, dewatering the mop and pressing the dewatering pressing plate (7) in the inner barrel with force, and then dewater the mop; and meanwhile, the drain valve (8) connected with the dewatering pressing plate (7) in a whole in the inner barrel is opened and the reset spring (13) is compressed. At this time, the sewage in the inner barrel flows into the filtering barrel (9) via the drain valve (8).
The cover plate (12) is fixedly connected with the dewatering pressing plate (7). The cover plate (12) falls down following the opening of the drain valve (8) due to pushing-down of the dewatering pressing plate. The water inlet valve (10) at the end part thereof closes a gap with the end port of the water inlet pipeline (5) to close the water inlet pipeline (5) while drawing the sewage as well, so the sewage is not reflowed into the outer barrel and the clean water in the outer barrel does not access into the middle barrel and the inner barrel.
After the mop is dewatered, the drain valve (8) is reset to close the inner barrel (4) by virtue of the resilience force of the reset spring (13) in case of lifting the mop to mop the floor. At the same time, the gap between the water inlet valve (10) and the end port of the water inlet pipeline (5) is recovered by the cover plate (12) along with the rise of the dewatering pressing plate (7), and then the water inlet valve (10) of the water inlet pipeline is opened.
By this time, the water in the middle barrel and the inner barrel has been discharged into the filtering barrel; the water level in the inner barrel is lower than the floater (6.1) of the water inlet quantity controller, the floater drops down to the cover plate (12), the water outlet valve (6.3) is separated from the end port of the water inlet pipeline (5) located below the water inlet valve (6.3) to communicate the outer barrel (2) and the middle barrel (3), the clean water in the outer barrel (2) re-accesses into the middle barrel again via the water inlet pipeline (%), and thus re-cleaning the mop with the clean water in the inner barrel when mopping the floor.
The frequency of the use of the clean water is determined by the volume of the outer barrel. The greater the volume is, the more the using time is.
The water inlet quantity from the outer barrel (2) to the middle barrel (3) is regulated by the water inlet quantity controller (6). The water inlet quantity each time is controlled by controlling the length of the water quantity regulating rod at one end of the floater. The longer the water quantity regulating rod at one end of the floater is than that at the other end, the smaller the water inlet quantity is.
The environment-protection energy-saving barrel according to the embodiment is fully made of engineering plastics, which is durable, environment-protection and energy-saving. In addition, the filtering barrel is provided with the plurality of clapboards for depositing and filtering. The sewage on the mop is seemed to be darker due to much dust and other micro-particles. The clapboards are used for depositing and filtering, so the vast majority of micro-particles are deposited at the bottom of the filtering barrel. Its principle is as bellows: the micro-particles in the still water will continue to sink to the bottom of the filtering barrel, while the filtering barrel is divided into 4 portions by the clapboards: the water in the first portion is not filtered, the water in the second portion is filtered once, the water in the third portion is filtered twice, and the water in the fourth portion is filtered three times, so the sewage after filtering several times can be reused, thus saving a lot of living water and being very environmentally friendly.
