The specific embodiment
The utility model has disclosed the mop system of the dust sensor of a kind of intelligent cleaning robot, preferred embodiment as shown in Figure 1 to Figure 3, comprise a housing 1, this housing 1 be the intelligent cleaning robot internal structure, two walls up and down that described housing 1 comprises two sidewalls 11 and connects these two sidewalls, the same with prior art, four above-mentioned walls have formed a dust channel 12, and the dust that is sucked by the intelligent cleaning robot can pass this dust channel 12.
Described two sidewalls 11 respectively are extended with a supporting walls 14 laterally, are a circle circular wall in this preferred embodiment, are fixedly connected with a cover plate 4 with this supporting walls 14, and described cover plate 4, supporting walls 14 and sidewall 11 form the enclosure space of a hollow.Have two optical signal elements 51,52 to be separately fixed on the cover plate 4 that is positioned at housing 1 both sides, one of them is a photocell 51, and another is a photoinduction element 52.The same with prior art, photocell 51 can send infrared signal, after this signal passes dust channel 12, can be sensed by photoinduction element 52, and the power of its signal can be detected by the intelligent cleaning robot, and judges the cleannes of present cleaning area.
In this preferred embodiment, cover plate 4 is provided with two holding pieces 41, and the optical signal element is forced between the holding piece 41, and both tight fits then this optical signal element promptly are held firmly, the afterbody of optical signal element exposes two contacts, in order to connect the power supply of optical signal element.Because supporting walls 14 be circular the setting, so cover plate 4 also is arranged to circle, and optical signal element 51,52 all is arranged on the position of off-centre relatively, and described photocell 51 and photoinduction element 52 be positioned on same the axis, so that can sense signal better.
The same with prior art, all respectively be provided with a light-passing board 3 between described optical signal element 51,52 and the adjacent separately sidewall 11, the infrared signal of sending in the optical signal element 51 can penetrate described light-passing board 3.
In this preferred embodiment, have a through hole 13 on the sidewall 11, the shape of through hole 13 does not limit in the utility model, can be illustrated rectangle, perhaps waits other shape for circle.Be set with a polishing piece 2 in the described through hole 13.The interior profile phase coupling of the outline of described polishing piece 2 and through hole 13 is so that can make both fix.Described polishing piece 2 is arranged between light-passing board 3 and the sidewall 11, and is close on the surface of inboard of light-passing board 3.In this preferred embodiment, the inside of described polishing piece 2 is provided with a hole 21, and the light that is used for photocell 51 is sent can pass from described hole 21, and is sensed by photoinduction element 52.Certainly, polishing piece 2 also can be to be strip always, only otherwise the transmission that stops optical signal gets final product.In the utility model, polishing piece 2 is made by easy Wiping material such as sponge or woollen goods.
All be provided with a hole in the center of cover plate 4 and light-passing board 3, be inserted in the hole of light-passing board 3 after having the motor drive shaft 61 of a motor 6 to pass cover plate 4, and fix with light-passing board 3.There is a boss inboard of light-passing board 3, rotatably is supported on the sidewall 11, and after motor 6 started, the rotation of motor drive shaft 61 can drive light-passing board 3 and rotate around motor axis.Because light-passing board was located at the both sides of housing 1 in 3 minutes, so two light-passing boards 3 are driven by a motor respectively in this preferred embodiment.Motor equally also is arranged on the both sides of housing 1.
When two motors 6 rotated, motor drive shaft 61 drove light-passing board 3 and rotates together, because polishing piece 2 is fixed, therefore between light-passing board 3 and the polishing piece 2 relative displacement was arranged this moment, therefore can will wipe out attached to the dust of light-passing board 3 inner surfaces.
Fig. 4 and Fig. 5 have disclosed second embodiment of the present utility model, be that with the difference of preferred embodiment described light-passing board 3 is rectangle, the one side is provided with tooth bar 31, the front end of described motor drive shaft 61 is provided with gear 62, described tooth bar 31 and gear 62 are meshed, one side of described light-passing board 3 also is provided with the spring 7 that is used to make light-passing board 3 answers, uses so that light-passing board 3 drives the reciprocating motion of back do perpendicular to motor axis by motor 6.Certainly, also can directly control positive and negative rotation of motor and get final product without spring 7.In the present embodiment, revolution, rack-and-pinion cooperates makes light-passing board 3 do rectilinear motion, because polishing piece 2 is fixed, therefore between light-passing board 3 and the polishing piece 2 relative displacement is arranged this moment, therefore can will wipe out attached to the dust of light-passing board 3 inner surfaces.After wiping finished, spring overcame rack-and-pinion and cooperates the resistance that is produced that light-passing board 3 is returned to initial position.
Fig. 6 has disclosed the 3rd embodiment of the present utility model, is that with the difference of preferred embodiment described motor drive shaft 61 passes dust channel 12, all fixedlys connected with the light-passing board 3 that is positioned at housing 1 both sides, in order to drive described two light-passing boards 3 simultaneously.The advantage of She Zhiing is to have saved a motor like this, provides cost savings.And the motor in the present embodiment also can be replaced by the main motor of robot, and promptly main motor drives the axle 61 that fixes with light-passing board 3 by a series of transmission devices commonly used, and simple example is for adopting gear drive.Can make the structure of robot interior compact more, simple like this.Certainly, second embodiment also can adopt the structure of present embodiment, promptly controls the reciprocating motion of two light-passing boards 3 with a motor.
The utility model still has multiple concrete embodiment.For example: polishing piece 2 is matched with the motor drive shaft 61 of motor 6, driven the back by motor 6 then and done rotation or reciprocating motion, and light-passing board 3 is arranged on corresponding fixed position.When revolution, make between light-passing board 3 and the polishing piece 2 and produce relative displacement, thereby will wipe out attached to the dust of light-passing board 3 inner surfaces.Because the structure and the embodiment that adopt are closely similar, so do not repeat them here.
All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
