The driving mechanism 30 is used for driving at least two cleaning assemblies 20 to rotate synchronously. The specific way of driving each cleaning assembly 20 to rotate synchronously by the driving mechanism 30 is many, for example, the driving mechanism 30 includes a driving member (e.g., a motor) and a driving gear driven by the driving member to rotate, the driving gear is respectively engaged with two driven gears, each driven gear is connected with a cleaning assembly 20, the driven gears rotate synchronously with the driving gear, so as to drive two cleaning assemblies 20 to rotate synchronously, of course, the two driven gears can also be engaged with other cleaning assemblies 20 provided with gears, so that the driving mechanism 30 can drive more than two cleaning assemblies 20 to rotate synchronously.

For another example, the driving mechanism 30 includes a driving member and at least two synchronizing wheels, the number of the synchronizing wheels is adapted to the number of the cleaning assemblies 20, each cleaning assembly 20 is connected to one synchronizing wheel, the synchronizing wheels are connected through a synchronous belt transmission, the motor drives one of the synchronizing wheels to rotate, the other synchronizing wheels are synchronously driven, and each cleaning assembly 20 also rotates along with the other synchronizing wheel.

Of course, the driving mechanism 30 can also drive at least two cleaning assemblies 20 to rotate synchronously through other structures, which is not described in detail herein.

Referring to fig. 1, 2 and 6, since the number of the cleaning assemblies 20 is two or more, and each cleaning assembly 20 has a certain distance therebetween, in order to facilitate the driving mechanism 30 to drive each cleaning assembly 20 to rotate synchronously, the driving mechanism 30 includes a transmission member 31 and a driving member 32, the transmission member 31 is in transmission connection with at least two cleaning assemblies 20, and the driving member 32 is in transmission connection with the transmission member 31 to drive at least two cleaning assemblies 20 to rotate synchronously.

Obviously, in combination with the above-mentioned embodiment, the transmission member 31 may be a gear assembly, and the transmission member 31 may also be a combination of a synchronous wheel and a synchronous belt; the transmission member 31 may also be a combination of a gear and a rack mounted on a slider of the linear motor, and specifically, the slider of the linear motor drives the rack to reciprocate, the gear engaged with the rack drives the cleaning component 20 connected thereto to rotate, the gear may also be engaged with other gears connected with the cleaning component 20 to drive other cleaning components 20 to rotate synchronously, and the transmission member 31 may also be other components, which are not listed herein.

The driving member 32 may be a rotary motor, a pneumatic rotary motor, a linear motor or an electric push rod, which is not limited in this respect, according to the choice of the transmission member 31.

The cleaning device 100 in the technical scheme of the utility model is provided with at least two cleaning assemblies 20, and each cleaning assembly 20 is driven by a single driving piece 32 to synchronously rotate, so that a power source is not correspondingly arranged on each cleaning assembly 20, and the purposes of simplifying the structure of the cleaning device 100 and reasonably saving the cost are achieved.

In some embodiments of the present invention, referring to fig. 1, fig. 2 and fig. 6, the transmission member 31 includes at least one first synchronizing wheel 311 and at least one second synchronizing wheel 312, the first synchronizing wheel 311 and the second synchronizing wheel 312 are respectively connected to the corresponding cleaning assembly 20, the first synchronizing wheel 311 and the second synchronizing wheel 312 are in transmission connection, and the first synchronizing wheel 311 drives the second synchronizing wheel 312 to rotate under the driving of the driving member 32.

Wherein, the first synchronizing wheel 311 and the second synchronizing wheel 312 are respectively connected with the corresponding cleaning assembly 20, which may specifically be: each first synchronizing wheel 311 is connected with at least one corresponding cleaning assembly 20, and each second synchronizing wheel 312 is connected with at least one corresponding cleaning assembly 20.

It can be understood that, on the one hand, the first synchronizing wheel 311 and the second synchronizing wheel 312 are both provided with a tooth structure, so that good transmission efficiency can be ensured; on the other hand, the first synchronizing wheel 311 and the second synchronizing wheel 312 have the advantages of simple structure, convenience in installation and the like, so that the structure can be simplified, and the assembly cost can be reduced.

In this case, the first synchronous wheel 311 and the second synchronous wheel 312 are not suitable for transmission by using tooth-to-tooth meshing, and preferably, the first synchronous wheel 311 and the second synchronous wheel 312 are in transmission connection through a synchronous belt.

In view of this, the transmission member 31 further includes at least one idle wheel 313, the idle wheel 313 is used for driving and connecting a first synchronous wheel 311 and a second synchronous wheel 312, so that the rotation directions of the first synchronous wheel 311 and the second synchronous wheel 312 are opposite, the rotation directions of the cleaning assemblies 20 connected with the first synchronous wheel 311 and the cleaning assemblies 20 connected with the second synchronous wheel 312 are opposite, but the opposite and contacting portions of the two cleaning assemblies 20 move in the same direction, so that the wear between the two cleaning assemblies 20 or between the cleaning members arranged on the two cleaning assemblies 20 is greatly reduced, the rotation of the two cleaning assemblies 20 is smoother, and the cleaning efficiency is improved.

With reference to the above embodiments, with continued reference to fig. 1 and fig. 6, the idle wheel 313 and the first synchronous wheel 311 are connected through a synchronous belt transmission, or/and the idle wheel 313 and the second synchronous wheel 312 are connected through a gear transmission. The beneficial effects of the connection between the idle wheel 313 and the first synchronous wheel 311 through the synchronous belt transmission can refer to the above embodiments, the principle is the same, and the details are not repeated herein; the idler wheel 313 and the second synchronizing wheel 312 directly engage with each other through teeth to ensure better transmission stability.

In other embodiments, the idle wheel 313 may also be connected to the second synchronous wheel 312 through a synchronous belt transmission, and the idle wheel 313 is connected to the first synchronous wheel 311 through a gear transmission; other transmission connection modes exist between the idle wheel 313 and the first synchronous wheel 311 and the second synchronous wheel 312, and are not described in detail herein.
