Technical field
The present invention relates to a kind of floor brush device of dust catcher, relate in particular to a kind of floor brush device that is used to do/wet two-purpose dust collector or steamvac.
Technical background
In the prior art, the scrubbing brush of doing/wet two-purpose dust collector or steamvac generally includes housing and the pipe joint that is arranged on the housing, pipe joint is connected with hard tube on the dust catcher, and lower housing portion has suction port, and suction port is connected with pipe joint by the dust absorption passage that is arranged in the housing.Generally also be provided with hairbrush and roller on the housing.During use, roller rotates suction nozzle is moved on surface to be cleaned more easily, by contacting of the hairbrush and the face of land, the dust on the face of land is brushed, and is beneficial to dedusting.
Yet for dried/wet two-purpose dust collector or steamvac, it is in the process of suction surface liquid to be cleaned, in case the power-off of main frame, because the suction of vacuum source reduces, the water that is extracted in the hard tube just can't continue to be extracted in the interior recycling bin of dust catcher.Liquid in the hard tube will flow backwards like this, flows back to ground along hard tube, has influenced cleaning effect.
Summary of the invention
The invention provides a kind of floor brush device of dust catcher, it can prevent that the liquid that aspirates from flowing back to surface to be cleaned because of refluence, reduces secondary pollution.
For achieving the above object, technical scheme of the present invention is, a kind of floor brush device of dust catcher, comprise scrubbing brush body and the pipe joint that is arranged on the scrubbing brush body, described scrubbing brush body is provided with suction port, described scrubbing brush body interior is provided with dust absorption passage, has tube chamber in the described pipe joint, described suction port is connected with tube chamber by dust absorption passage, the floor brush device of described dust catcher also comprises the water tank with water inlet, being arranged on scrubbing brush body or the pipe joint to small part of described water tank, tube chamber or dust absorption passage in the water inlet of described water tank and the pipe joint are connected, under atmospheric pressure state, the liquid in described tube chamber or the dust absorption passage can flow in the water tank by water inlet.
The floor brush device of described dust catcher also comprises the return flow line, and the tube chamber in the described pipe joint is connected with the water inlet of water tank by the return flow line, and described return flow line is arranged in the scrubbing brush body.
The floor brush device of described dust catcher also comprises catch tray and mozzle, and the bottom of described pipe joint is the tube chamber opening, and described catch tray is arranged on the below of tube chamber opening, and described return flow line is catch tray and the mozzle that communicates.
The floor brush device of described dust catcher also comprises the reverse flow baffle that is arranged on regularly on the scrubbing brush body, and the part of described reverse flow baffle relatively is provided with described tube chamber opening.
Described reverse flow baffle is arranged on the described catch tray regularly or integratedly.
Have discharge outlet on the described water tank.
Technical scheme of the present invention compared with prior art, its scrubbing brush body or pipe joint are provided with water tank, and under atmospheric pressure state, liquid in described tube chamber or the dust absorption passage can flow in the water tank by water inlet, therefore, and behind the power-off of dust catcher, even the liquid that is extracted in the hard tube reduces to flow backwards because of the suction of vacuum source, liquid in the pipe also can flow to water tank from the tube chamber in the pipe joint, prevents that the liquid that aspirates from flowing back to surface to be cleaned because of refluence, reduces secondary pollution.

The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the invention is elaborated.In the following description, the same numeral in the different accompanying drawings is used in reference to components identical.
Embodiment one
Shown in accompanying drawing 1, accompanying drawing 2 and accompanying drawing 5, a kind of floor brush device of dust catcher comprises scrubbing brush body 1 and the pipe joint 2 that is arranged on the scrubbing brush body 1.Described scrubbing brush body 1 comprises housing 11, base plate 6 and is arranged on hairbrush 20 and roller 21 on the base plate 6.Have suction port 3 on the base plate 6.Described scrubbing brush body 1 inside is provided with dust absorption passage 4, has tube chamber 5 in the described pipe joint 2, and described suction port 3 is connected with tube chamber 5 by dust absorption passage 4.
The floor brush device of described dust catcher also comprises water tank 7.Described water tank 7 comprises loam cake 18 and lower box 17, and described water tank 7 is fastened mutually by described loam cake 18 and lower box 17 and forms.The top of described water tank 7 is provided with water inlet 19, and the sidepiece of described water tank 7 has discharge outlet 15.Also be extended with pair of brackets 23 on the housing 22 of described scrubbing brush body 1, described water tank 7 is arranged on this on the support 22.The water inlet 19 of described water tank 7 is connected by the tube chamber 5 in return flow line 8 and the pipe joint 2, and described return flow line 8 is arranged in the scrubbing brush body 1; Under atmospheric pressure state, the liquid in the described tube chamber 5 can flow in the water tank 7 by water inlet 19.
Those skilled in the art it will also be appreciated that this water tank 7 can also be connected directly on the pipe joint 2, and pipe joint 2 and water tank 7 are connected.
The floor brush device of described dust catcher also comprises catch tray 9 and mozzle 10, and the bottom of described pipe joint 2 is a tube chamber opening 12, and described catch tray 9 is arranged on the below of tube chamber opening 12.Catch tray 9 and the mozzle 10 of described return flow line 8 for communicating.Described water tank 7 is connected with tube chamber 5 in the pipe joint 2 by mozzle 10, catch tray 9.
The floor brush device of described dust catcher also comprises reverse flow baffle 13, and the part of described reverse flow baffle 13 relatively is provided with described tube chamber opening 12.
As shown in Figure 6, the tube wall 14 of described dust absorption passage 4, catch tray 9, reverse flow baffle 13 and mozzle 10 are for being provided with integratedly.Described catch tray 9 is " pallet " formula structure, and the tube wall 14 of described dust absorption passage 4 and reverse flow baffle 13 all are arranged on the catch tray 9, and reverse flow baffle 13 constitutes the part of the tube wall 14 of dust absorption passage 4.The sidepiece of described catch tray 9 has opening, is connected with an end opening of mozzle 10.The other end open communication of described mozzle 10 is to the water inlet 19 of water tank 7.
