Referring now to fig. 1-13, a floor brush assembly 100 for a floor scrubbing machine according to an embodiment of the present invention is described.

As shown in fig. 1 to 3, a floor brush assembly 100 of a floor washing machine according to an embodiment of the present invention includes: a housing 1 and a rolling brush mechanism 2.

A first channel 101 and a second channel 102 are arranged in the shell 1, an inlet and outlet hole 121 is arranged on the shell 1, and the inlet and outlet hole 121 is communicated with the first channel 101 and the second channel 102; the round brush mechanism 2 is established on shell 1, and round brush mechanism 2 includes: the motor 22 is connected with the rolling brush 21 to drive the rolling brush 21 to rotate, a heat dissipation system is arranged in the motor 22, the air guide shell 23 is arranged on the motor 22 and used for ventilating and dissipating heat of the motor 22, an air inlet channel 2301 and an air outlet channel 2302 are arranged on the air guide shell 23, the air inlet channel 2301 is communicated with the first channel 101, and the air outlet channel 2302 is communicated with the second channel 102.

It can be understood that the heat dissipation system may be a heat dissipation fan (not shown), the motor 22 further includes a rotor assembly (not shown), the specific structure of the rotor assembly may refer to the prior art, and details are not described herein, the rotor drives the heat dissipation fan and the rolling brush 21 to rotate, the rolling brush 21 rotates to be used for cleaning the ground, when the heat dissipation fan rotates, a negative pressure is formed at one side of the heat dissipation fan, the driving air enters from the air inlet channel 2301, heat exchange is performed to form hot air when passing through the winding portion of the rotor, and the hot air is discharged from the air outlet channel 2302 to achieve heat dissipation. The first channel 101 and the second channel 102 in the housing 1 form an airflow path for air intake and air exhaust, when the rolling brush mechanism 2 works and dissipates heat, external cold air enters the first channel 101 from the inlet/outlet hole 121, enters the air guide shell 23 from the air intake channel 2301, exchanges heat with the winding part in the motor 22, and then flows to the inlet/outlet hole 121 from the second channel 102 through the air exhaust channel 2302 and is finally discharged outwards.

According to the floor brush device 100 of the floor washing machine, the first channel 101 and the second channel 102 are arranged in the shell 1, the shell 1 is provided with the inlet and outlet holes 121, the inlet and outlet holes 121 are communicated with the first channel 101 and the second channel 102, the first channel 101 and the second channel 102 are used as an air inlet path and an air outlet path of the rolling brush mechanism 2, and the inlet and outlet paths are communicated with the inlet and outlet holes 121, so that the air inlet distance and the air outlet distance are relatively short, and the waterproof requirement is easily met.

In some embodiments, as shown in fig. 1, the access hole 121 is formed on the side end 106 of the casing 1, so that the floor brush device 100 of the floor washing machine can prevent water stains from above from entering the access hole 121 during use, and further realize water resistance. The access hole 121 is disposed away from the bottom of the side end portion 106, and when the environment outside the housing 1 has a certain water level, the position of the access hole 121 on the side end portion 106 is designed to be higher, so that the probability of water inflow can be reduced.

For example, as shown in fig. 1, the inlet/outlet hole 121 is provided on the upper side of the side end portion 106, so that it is possible to prevent external water from entering the inlet/outlet hole 121.

In some embodiments, as shown in fig. 2 and 3, a plurality of water baffles 107 are disposed on the access hole 121, the water baffles 107 are spaced apart from each other in the up-down direction, and each water baffle 107 is disposed obliquely downward toward the outer side of the access hole 121. That is, when water comes from a side direction and collides with the housing 1, the water can flow obliquely downward along the water guard 107 by the water guard 107 disposed obliquely downward, that is, the water from the side direction guided by the water guard 107 is not easily introduced into the inlet and outlet hole 121. Secondly, adopt this kind of mode of hiding a plurality of breakwaters 107 in business turn over hole 121, can realize waterproof requirement and also can guarantee that its whole aesthetic property is better simultaneously. Alternatively, the water guard plate 107 may be provided in three.

In some embodiments, as shown in fig. 3, the first channel 101 and the second channel 102 are disposed on the side end 106, that is, the access hole 121 and the first channel 101 and the second channel 102 are disposed on the same side of the housing 1, which can reduce the airflow path and provide better heat dissipation and cooling effects for the motor 22. Secondly, the first channel 101 and the second channel 102 are arranged on the same side of the housing 1, so that the housing 1 can be conveniently machined into the first channel 101 and the second channel 102 at the same time during manufacturing, and the machining difficulty is reduced.

Specifically, the first channel 101 and the second channel 102 may be disposed at any one of the front, rear, left, and right side ends of the casing 1, and since the top and bottom of the casing 1 generally need to be provided with a cover plate structure for assembly and disassembly to replace internal components, the first channel 101 and the second channel 102 are disposed at the side ends of the casing 1 in the horizontal direction without disassembly, so that the first channel 101 and the second channel 102 are always intact, and the problem of inaccurate positions of the first channel 101 and the second channel 102 due to disassembly and reassembly can be avoided.

For example, as shown in fig. 4, the rolling brush mechanism 2 is provided on the front side of the housing 1, and the first passage 101 and the second passage 102 are provided on the left side of the housing 1; alternatively, the rolling brush mechanism 2 is arranged at the front side of the housing 1, and the first channel 101 and the second channel 102 are arranged at the right side of the housing 1; alternatively, the rolling brush mechanism 2 is provided on the lower side of the housing 1, and the first passage 101 and the second passage 102 are provided on the rear side of the housing 1. Of course, the above is only an example, and the positions of the first channel 101 and the second channel 102 may have other arrangement manners, which is not limited to this, and are not described herein again.

In some embodiments, the first channel 101 and the second channel 102 extend along the length direction and/or the width direction of the side end. Taking the example in which the first channel 101 and the second channel 102 are provided at the left end of the housing 1, the first channel 101 and the second channel 102 may extend along the longitudinal direction of the left end, which is the front-rear direction in the drawing, and the first channel 101 and the second channel 102 constitute an elongated channel extending in the front-rear direction. The first channel 101 and the second channel 102 may extend in the width direction of the left end portion, the width direction of the left end portion being the vertical direction, and the first channel 101 and the second channel 102 may form an elongated channel extending in the vertical direction. The first channel 101 and the second channel 102 can also extend along the length direction and the width direction of the left end part at the same time, so that the cross-sectional sizes of the first channel 101 and the second channel 102 are large, and air inlet and air outlet are facilitated.

Of course, the above description is only an example, and the first channel 101 and the second channel 102 are provided on other side end portions (e.g., a right side end portion, a rear side end portion, etc.) of the housing 1 so as to be provided on a left side end portion in the same manner, and are not described again here.

In some embodiments, the first channel 101 has a larger cross-section in a vertical reference plane parallel to the axial direction of the roller brush 21 than the second channel 102. Therefore, the air inlet surface of the air inlet path formed by the first channel 101 is larger, the air inlet is facilitated, the air inlet volume is obviously increased, and the heat dissipation effect of the rolling brush mechanism 2 is enhanced.

In some embodiments, as shown in fig. 4, the housing 1 includes: the rolling brush device comprises a main body part 11, an outer plate part 12 and an inner plate part 13, wherein a groove 111 is arranged on the main body part 11, and the rolling brush mechanism 2 is arranged on the main body part 11; the outer plate 12 is arranged in the groove 111, and the access hole 121 is arranged on the outer plate 12; the inner panel 13 is disposed between the groove 111 and the outer panel 12, the inner panel 13 and the groove 111 define a first channel 101 therebetween, the inner panel 13 and the outer panel 12 define a second channel 102 therebetween, and the distance between the inner panel 13 and the groove 111 is greater than the distance between the inner panel 13 and the outer panel 12. By arranging the shell 1 to comprise the main body part 11, the outer plate part 12 and the inner plate part 13, the first channel 101 is defined between the inner plate part 13 and the groove 111, and the second channel 102 is defined between the inner plate part 13 and the outer plate part 12, the first channel 101 and the second channel 102 are formed by reasonably utilizing the assembly of the plate parts, the structural design is ingenious, the forming is easy, and the processing difficulty of the first channel 101 and the second channel 102 can be reduced.

The distance between the inner plate 13 and the groove 111 is greater than the distance between the inner plate 13 and the outer plate 12, so that the gap (i.e., the first channel 101) formed between the inner plate 13 and the groove 111 is greater than the gap (i.e., the second channel 102) formed between the inner plate 13 and the outer plate 12, which is beneficial to improving the air intake amount and ensuring the ventilation and heat dissipation of the motor 22.

In some embodiments, as shown in fig. 3 and 4, the groove 111 is provided with a first air inlet 112 communicated with the air inlet channel 2301, the groove 111 is provided with a cylinder 113 communicated with the air outlet channel 2302, the inner plate 13 is provided with a mounting hole 131, the cylinder 113 is disposed in the mounting hole 131, the inner plate 13 is provided with a second air inlet 132, and the outer plate 12 is provided with an inlet/outlet hole 121. During heat dissipation, air enters from the inlet and outlet holes 121, enters the first channel 101 through the second air inlet holes 132 of the inner plate 13, then enters the air inlet channel 2301 through the first air inlet holes 112, and hot air enters the second channel 102 through the air outlet channel 2302 through the cylinder 113 and is discharged from the inlet and outlet holes 121 of the outer plate 12. By adopting the mode, the first channel 101 and the second channel 102 can be stacked, the structure is compact, the space can be saved, meanwhile, the barrel 113 is matched with the mounting hole 131, the air inlet of the first channel 101 and the air outlet of the second channel 102 can be guaranteed not to be interfered with each other, and the structural design is ingenious.

In some embodiments, as shown in fig. 4, the second air inlet holes 132 are provided in plural, and the plural second air inlet holes 132 are provided at intervals in the inner panel 13, and the provision of the plural second air inlet holes 132 can improve the air inlet capacity of the first duct 101.

In some embodiments, one of the second air inlet holes 132 is disposed opposite to the access hole 121, so that the air directly enters the second air inlet hole 132 from the access hole 121, which facilitates the quick air inlet of the rolling brush mechanism 2.

In some embodiments, as shown in fig. 4, a plurality of supporting members 114 are disposed on the groove 111, and the plurality of supporting members 114 all abut against the inner plate 13. Because the inner plate 13 is a thin plate, the support members 114 can support the inner plate 13, and the first channel 101 formed between the inner plate 13 and the groove 111 is stable and reliable.

Alternatively, as shown in fig. 4, the supporting member 114 is a supporting column, one end of which is disposed on the groove 111 and the other end of which abuts against the inner plate 13.

In some embodiments, as shown in fig. 2, 3 and 5, the air inlet channel 2301 and the air outlet channel 2302 are disposed on the same side of the air guiding shell 23 and are arranged side by side. Because the air inlet channel 2301 and the air outlet channel 2302 which are arranged side by side are arranged on the same side of the air guide shell 23, air outlet and air inlet on the same side can be realized when the rolling brush mechanism 2 dissipates heat, and the arrangement of the rolling brush mechanism 2 in the floor brush device 100 of the floor washing machine is facilitated.

In some embodiments, as shown in fig. 5 and fig. 6, the motor 22 includes a housing 221, the heat dissipation system is disposed in the housing 221, an air inlet 2211 and an air outlet 2212 are disposed on the housing 221, the air guiding shell 23 is disposed on the housing 221 and defines an air inlet cavity and an air outlet cavity with the housing 221 therebetween, the air inlet cavity and the air outlet cavity are separately disposed, the air inlet cavity communicates with the air inlet 2211 and the air inlet passage 2301, and the air outlet cavity communicates with the air outlet 2212 and the air outlet passage 2302. An airflow path required by heat dissipation is defined between the air guide shell 23 and the casing 221, air enters the air inlet cavity through the air inlet channel 2301, then enters the casing 221, exchanges heat with the winding part of the rotor, then hot air enters the air outlet cavity through the air outlet 2212, and finally is discharged from the air outlet channel 2302 (see fig. 1, wherein the arrow direction is the flowing direction of the air), and the arrangement of the air inlet path and the air outlet path for heat dissipation of the motor 22 is more compact by adopting the mode.
