Floor brush of dust collector 10 according to embodiments of the present invention is described in detail below with reference to Fig. 1-Fig. 2.
As Figure 1-Figure 2, floor brush of dust collector 10 according to embodiments of the present invention includes：Housing 1 it is different with function
One round brush 2 and the second round brush 3, that is to say, that the first round brush 2 and the second round brush 3 have chosen two kinds of work(in practical cleaning works
The different round brush of energy, the two cooperate, so that dust catcher efficiency is more preferable, pick-up performance is more preferable.
Housing 1 limits round brush holding tank 11 and air duct 12, and round brush holding tank 11 is connected with air duct 12, in this way by the first rolling
The dust or particulate matter that 2 and second round brush 3 of brush has been brushed can be entered by air duct 12 in dust catcher, can realize dust catcher
The purpose of dedusting work.
Wherein, the first round brush 2 and the second round brush 3 are respectively positioned in round brush holding tank 11, and the first round brush 2 is located at the second round brush 3
Front side, and the first round brush 2 and the second round brush 3 contact with each other, when bulky grain or clast are taken to by the first round brush 2 in air duct 12
When, since the first round brush 2 and the second round brush 3 have amount of interference, the second round brush 3 can be under the bulky grain object obstruction on the first round brush 2
Come, thereby may be ensured that the bulky grain object at the first round brush 2 can enter in dust catcher.
Also, diaphragm structure is eliminated between the first round brush 2 and the second round brush 3, can prevent from blocking at the first round brush 2
Bulky grain object can effectively solve the problems, such as to block bulky grain object at the first round brush 2, so as to promote floor brush of dust collector
10 working performance, and then the efficiency of dust collection of floor brush of dust collector 10 can be promoted, it is also possible to promote the satisfaction of user.
Coordinated as a result, by housing 1, the first round brush 2 and the second round brush 3, can prevent from blocking bulky grain at the first round brush 2
Object can effectively solve the problems, such as to block bulky grain object at the first round brush 2, so as to promote the work of floor brush of dust collector 10
Make performance, and then the efficiency of dust collection of floor brush of dust collector 10 can be promoted, it is also possible to promote the satisfaction of user.
Optionally, in a part the first round brush 2 of intrusion of the second round brush 3, such setting can make the first round brush 2 and second
Round brush 3 better contacts with, it is ensured that the first round brush 2 and the second round brush 3 generate interference in rotation process, thereby may be ensured that
Second round brush 3 stops the bulky grain object on the first round brush 2.
Further, the first round brush 2 can be villus brush, and the second round brush 3 can be carpet brush, and such setting can make two
A round brush is preferably contacted with dedusting face, it is ensured that two round brush can stir the dust on dedusting face or particulate matter
Come, so as to dust or particulate matter inspiration dust catcher, and then dust removing effects can be promoted.
Specifically, as shown in Figure 1, the peripheral wall of round brush holding tank 11 can include：First segmental arc 111 and the second segmental arc
112, the first segmental arc 111 is connected to the front side of the second segmental arc 112, and the first segmental arc 111 is correspondingly arranged with the first round brush 2,
And second segmental arc 112 be correspondingly arranged with the second round brush 3, it should be noted that the first round brush 2 is arranged on round brush holding tank 11
The lower section of the first interior segmental arc 111, the second round brush 3 are arranged on the lower section of the second segmental arc 112 in round brush holding tank 11, such as
This setting can make that the first round brush 2 and the second round brush 3 arrange more rationally, the first round brush 2 and the second round brush 3 can be promoted
Working performance, meanwhile, it can also prevent the first round brush 2 and the second round brush 3 from generating interference with round brush holding tank 11, it is ensured that the
One round brush 2 and the second round brush 3 work normally.
Optionally, as shown in Fig. 2, floor brush of dust collector 10 can also include：Drive component 4 and transmission component 5, drive component
4 are driven with the second round brush 3, and transmission component 5 is arranged between the first round brush 2 and the second round brush 3, wherein, drive component 4 can be
The rotation of second round brush 3 provides power, can rotate the second round brush 3, so as to be further ensured that the work of the second round brush 3
Reliability.
In addition, transmission component 5 has gearing, it, can by the transmission of transmission component 5 when the second round brush 3 rotates
Make the first round brush 2 that the second round brush 3 be followed to rotate together, can realize the work mesh that the first round brush 2 and the second round brush 3 rotate together
,.
Further, as shown in Fig. 2, drive component 4 can include：Motor 41 and conveyer belt 42, conveyer belt 42 are set in
On the driving end of the motor shaft of motor 41 and the second round brush 3, it is to be understood that one end of conveyer belt 42 is set in motor 41
On motor shaft, the other end of conveyer belt 42 is set on the driving end of the second round brush 3, when motor 41 works, the electricity of motor 41
Arbor rotates, and then by the effect of conveyer belt 42, can make the driving end of the second round brush 3 that the second round brush 3 be driven to rotate, and
The transmission effect of conveyer belt 42 is good, stable drive, can promote the functional reliability of floor brush of dust collector 10.
Specifically, as shown in Fig. 2, transmission component 5 can include：First gear 51, intermediate gear 52 and second gear 53,
First gear 51 is fixed on the driving end of the first round brush 2, and second gear 53 is fixed on the driving end of the second round brush 3, center tooth
Wheel 52 is engaged between first gear 51 and second gear 53, and when the second round brush 3 rotates, the driving end of the second round brush 3 can turn
Dynamic, then the driving end of the second round brush 3 can be rotated with intermediate gear 52, and then intermediate gear 52 can drive 51 turns of first gear
Dynamic, the rotation of first gear 51 can drive the driving end of the first round brush 2 to rotate, and the driving end of the first round brush 2 can drive the first round brush 2
Rotation, so as to realize that the second round brush 3 drives the work purpose that rotates together of the first round brush 2.
Wherein, the transmission capacity of first gear 51, intermediate gear 52 and second gear 53 is strong, bearing capacity is strong, torque is big,
Stable drive, when the surface of the first round brush 2 has attached clast, such setting can ensure what the surface of the first round brush 2 attached
Clast is easy to be sucked into dust catcher, can prevent 2 stall of the first round brush, is encountered so as to effectively solve the first round brush 2
It attaches the clast stall on surface the problem of.
Optionally, intermediate gear 52 can be duplex-gear gear, and duplex gear can include：Big gearing part and small teeth portion,
Big gearing part is engaged with second gear 53, and small teeth portion is engaged with first gear 51, and the functional reliability of duplex gear is good, transmission effect
Rate is high, it is ensured that the second round brush 3 preferably drives the first round brush 2 to rotate.
Further, first gear 51, intermediate gear 52 and second gear 53 all can be helical gear, between helical gear
Engagement property is good, the transmission between first gear 51, intermediate gear 52 and second gear 53 can be made more steady, and also can
Reduce the rotational noise between first gear 51, intermediate gear 52 and second gear 53, meanwhile, can also make first gear 51,
Registration between intermediate gear 52 and second gear 53 becomes larger, and can reduce first gear 51,52 and second tooth of intermediate gear
The load of wheel 53, so as to improve the bearing capacity of first gear 51, intermediate gear 52 and second gear 53..
