Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Refer to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the utility model ground brush assemblies 100 comprises housing 10 and is arranged on the pushing mechanism 20 on described housing 10.Described housing 10 comprises ground brush holder 11 and pivot joint is arranged on dirt lid 12 on described ground brush holder 11.Described pushing mechanism 20 comprises crank 21, push rod 22 and flexible member 23.The two ends of described crank 21 are respectively arranged with the first pivot 211 and the second pivot 212.Described crank 21 is arranged on described dirt lid 12 by described first pivot 211 pivot joint, is arranged on described push rod 22 by described second pivot 212 pivot joint.Described crank 21 is roughly V-shaped.Although in the present embodiment, the shape of described crank 21 is V-type, and in other embodiments, the shape of described crank 21 can be established according to needing.Described push rod 22 is generally u-shaped, is arranged on described ground brush holder 11.Described push rod 22 comprises and is positioned at described housing 10 outside with the pushing portion 221 offseted with other object (such as, wall) and the adjutage 222 extended to form from two lateral bucklings of described pushing portion 221, and described adjutage 222 part is positioned at described housing 10.Although in the present embodiment, described push rod 22 is U-shaped, and in other embodiments, described push rod 22 can also be L-type.One end of described flexible member 23 is arranged on described push rod 22, and the other end is arranged on described housing 10.When promoting described push rod 22, there is elastic deformation in described flexible member 23, described crank 21 promotes described dirt lid 12 and overturns under the effect of described push rod 22.When unclamping described push rod 22, described flexible member 23 resets, and described push rod 22, crank 21, dirt lid 12 reset under the effect of described flexible member 23.

Figure 3 shows that the first embodiment of pushing mechanism 20.One end of described flexible member 23 is arranged on one end that described adjutage 222 deviates from described pushing portion 221, and the other end is arranged on described ground brush holder 11.When promoting described push rod 22, described flexible member 23 is compressed, and now described flexible member is stage clip.

Figure 7 shows that the second embodiment of pushing mechanism 20 '.Described pushing mechanism 20 ' is substantially identical with the structure of described pushing mechanism 20, difference is one end that one end of flexible member 23 ' is arranged on described adjutage 222 and deviates from described pushing portion 221, the other end is arranged on one end of the contiguous described pushing portion 221 of described dirt lid 12, that is: described flexible member 23 ' one end be arranged on described push rod 22 is positioned at the side that described crank 21 deviates from described pushing portion 221, and the one end be arranged on described dirt lid 12 is positioned at the side of the contiguous described pushing portion 221 of described crank 21.When promoting described push rod 22, described flexible member 23 ' is stretched, and now described flexible member 23 ' is extension spring.

Figure 8 shows that pushing mechanism 20 ' ' the 3rd embodiment.Described pushing mechanism 20 ' ' the structure of structure and described pushing mechanism 20 substantially identical, difference is flexible member 23 ' ' is torsion spring, a reverse arm and the effect of described push rod 22 phase of described torsion spring, another reverse arm and the effect of described housing 10 phase.When promoting described push rod 22, described flexible member 23 ' ' twist deformation, and described crank 21 promotes described dirt lid 12 and overturns under the effect of described push rod 22; Reset under the effect of when unclamping described push rod 22, described flexible member 23 ' ' reset, described push rod 22, crank 21, dirt lid 12 are at described flexible member 23 ' '.

When using ground described in the utility model brush assemblies 100, directly the objects such as described push rod 22 and wall are offseted, described dirt lid 12 is overturn, thus makes described ground brush assemblies 100 can clean the corner formed between wall and ground, can effectively avoid occurring cleaning blind area.When cleaning bottom furniture, can also so operate.

Compared to prior art, the utility model ground brush assemblies 100 can effectively clean the places such as the corner formed bottom furniture, between wall and ground, effectively avoids occurring cleaning blind area.

Of particular note, for the person of ordinary skill of the art, do under instruction of the present utility model for equivalence change of the present utility model, must be included in the scope that the utility model claim advocates.
