In order to clearly describe the behavior of robot, carry out following direction definition: robot 100 can by relative to It is advanced on the ground by the various combinations that the following three that main body 110 defines is mutually perpendicular to the movement of axis: lateral shaft x, antero posterior axis y And central vertical shaft z.It is " forward direction " along the forward hand designations of antero posterior axis y, and along the backward driving side of antero posterior axis y To being denoted as " backward ".The axle center that lateral shaft x is substantially defined along the central point by driving wheel module 141 is in robot Right wheel and revolver between extend.Wherein, robot 100 can be rotated around x-axis.When the forward portion of robot 100 is to updip Tiltedly, it is when partially tilting down backward " facing upward ", and when the forward portion of robot 100 tilts down, backward partially to updip It is when tiltedly " nutation ".In addition, robot 100 can be rotated around z-axis.On the forward direction of robot, when robot 100 is to Y Axis right side inclination be " right-hands rotation ", when robot 100 to the left side of y-axis be " left-hand rotation ".

In the technical solution of the disclosure, by changing to the cleaning systems 150 being equivalent in above-mentioned robot 100 Into the available wind path structure optimized under structure, to can reduce the gas in wind path structure under identical dynamic condition Stream loss, improves dust collection efficiency.Below with reference to embodiment, the technical solution of the disclosure is described.

Fig. 5 is a kind of cross-sectional view of the wind path structure of automatic cleaning equipment shown according to an exemplary embodiment； Wherein, when automatic cleaning equipment shown in fig. 5 is robot 100 or other similar equipment as shown in Figs 1-4, this is automatic The wind path structure of cleaning equipment can correspond to the cleaning systems 150 of above-mentioned robot 100.For ease of description, Fig. 5 is shown The directional information of automatic cleaning equipment in one exemplary embodiment, including the direction of travel along y-axis (in which it is assumed that y-axis is left Side direction is forward direction, i.e. "+"；Y-axis right direction be after to driving direction, i.e. "-") and along z-axis vertical direction.

As shown in figure 5, the wind path structure of automatic cleaning equipment may include: cleaning member 1, cleaning object storage member 2, Power part 3, level-one air duct 4 and second level air duct 5.Wherein, cleaning member 1, cleaning object storage member 2 and 3 edge of power part The direction of travel of automatic cleaning equipment, that is, direction y is arranged successively, and level-one air duct 4 is located at cleaning member 1 and cleaning object storage Between component 2, second level air duct 5 be located at cleaning object storage member 2 and power part 3 between.So, embodiment shown in fig. 5 Following air ducts: 1 → level-one of cleaning member air duct 4 → 5 → power part of cleaning 2 → second level of object storage member air duct can be formed Part 3, the wind that power part 3 is generated realize the flowing from cleaning member 1 to power part 3 by above-mentioned air duct, and Flow direction is shown by the arrow direction in Fig. 5；Wherein, the wind that power part 3 generates is in cleaning member 1, level-one air duct 4 and clear When flowing between clean object storage member 2, dust, the graininess rubbish that cleaning member 1 can be cleaned etc. clean object conveying Into cleaning object storage member 2, clean operation is realized.

Sweeping efficiency DPU is the accurate embodiment of the cleaning capacity of automatic cleaning equipment, sweeps effect by suction efficiency and round brush Both rates codetermine, and based on suction efficiency discussed herein, suction efficiency is the accurate embodiment of dust removal ability, is embodied electric energy It is converted into the efficiency of mechanical energy, suction efficiency=sucking power/input power, input power is the electricity of the input of blower motor Can, power=air quantity * vacuum degree is sucked, after input power increases to certain value, starts the air quantity for generating sucking, with input work The increase of rate, air quantity are continuously increased, and vacuum degree is gradually reduced, and sucking power then is first to increase to reduce afterwards, makes input power work Make in the sucking higher range of power.

For same input power, air quantity and vacuum degree are all more big more can obtain high suction efficiency.Vacuum degree Loss reduce and depend on avoiding of leaking out namely encapsulation process.The loss reduction of air quantity depends on smooth without steep The wind path structure of change, specifically specifically includes that whether wind nondestructively enters air duct from round brush lower end, and wind is blowed to from round brush lower end Dirt box enters by the number of wide-angle reflection during blower, and whether duct cross-section product generates a large amount of turbulent flow when changing Etc..The overall construction design of wind path can all generate complete machine dust collection efficiency as organic whole, the structure change of a component Great variety.

Because round brush is as cleaning member 1, the more wide then single cleaning width of width is wider, and dirt box is as cleaning object Storage member 2 is co-located in shell with components such as traveling wheels, and restricted width cannot be very wide, and in order to increase vacuum Fine pressure is rubbish to be drawn into dirt box, and the entrance of dirt box can not be very wide, therefore there are first between round brush and dirt box Air duct, and section is gradually small；The outlet of dirt box is by strainer filtering air, in order to avoid the blocking influence air duct of strainer is unimpeded, Dirt box discharge area is usually larger, and blower is as power part 3, and entrance hole diameter is then much smaller than the outlet of dirt box, therefore dirt There are the second air ducts between box and blower, and section is also gradually small.At present, although there are the wind paths of part automatic cleaning equipment It is middle to use such two air ducts, such as the Roomba series sweeping robot of iROBOT, but not using for the two wind Do the wind path structure of optimization design in road.

Although in fact, all can include round brush, dirt box, blower in wind path, or even can have two sections gradually small air duct, But the difference of air duct shape makes suction efficiency far from each other.

Wind path in the disclosure makes the round brush lower end of wind self-relocation enter air duct, because floating round brush can be in different height It can be tightly bonded with ground in region to be cleaned, wind loss very little.The realization of floating round brush is derived from the soft of level-one air duct Property material properties and make round brush with topography variation and flexible structure design up and down.

Round brush enters level-one air duct by round brush accommodating chamber, and the shape in level-one air duct increases the fine pressure value of wind smoothly, will Rubbish is moved into dirt box obliquely；It is anti-with big angle of reflection at the top of dirt box after the gradient in level-one air duct makes wind enter dirt box It penetrates and leaves dirt box；Rubbish into dirt box falls under gravity into dirt cassette bottom portion, and the wind moved obliquely is by dirt box top Portion is blown out with exporting after big angle of reflection from strainer, into second level air duct；Wherein, the purpose of design in second level air duct is to make The wind blown out from strainer enters blower mouth with certain orientation with losing less as far as possible.

Each structure in wind path is described in detail below:

1, the smooth guide in second level air duct 5

Fig. 5 is the top view of the wind path structure of one exemplary embodiment of the disclosure.As shown in figure 5, cleaning member 1, cleaning Object storage member 2 and power part 3 while the direction of travel (i.e. y-axis direction) along automatic cleaning equipment is arranged successively, Cleaning object storage member 2 also deviates from each other on x-axis direction (i.e. the left and right directions of automatic cleaning equipment) with power part 3, When thus wind blows to power part 3 from cleaning object storage member 2, the fortune on along the y-axis direction and along the x-axis direction is existed simultaneously Dynamic, i.e., there is " turning " in flow process in wind.Certainly, cleaning object storage member 2 and power part 3 can also be in x-axis directions Upper nothing deviates from each other, and the disclosure is limited not to this.

As shown in figure 5, second level air duct 5 is in the shape of a trumpet, (the side sectional area of close cleaning object storage member 2 is relatively Greatly, relatively small close to the side sectional area of power part 3) so that wind is gathered to the air inlet of power part 3.Wind is from clear When clean object storage member 2 is blown into second level air duct 5, due to the reduction of sectional area, wind is the windward side for directly blowing to second level air duct 5 51 inner wall；So in the technical solution of the disclosure, by configuring arc for the inner wall windward side in the second level air duct 5, one The wind that aspect can in the direction of the x axis export cleaning object storage member 2 guides, it is made to be blown to power part 3 On the other hand air inlet can be matched with the flowing of wind, avoid causing to stop to it or interfere to generate turbulent flow, to help to drop Low-flow loss improves air quantity utilization rate.

Meanwhile cleaning after object cleaned by cleaning member 1, the wind that is generated by power part 3 (and level-one air duct 4 Structure cooperation) it is transported in cleaning object storage member 2, thus the air quantity utilization rate by promoting wind path structure, reduction gas Stream loss can increase wind to the conveying intensity of cleaning object, to promote the cleannes and cleaning efficiency of automatic cleaning equipment.

Fig. 6 shows separately the top view in second level air duct 5.As shown in fig. 6, being received in the second level air duct 5 far from cleaning object Receive component 2 end (under visual angle shown in Fig. 6, cleaning object storage member 2 should be located at second level air duct 5 lower section, then End, that is, upper end far from the cleaning object storage member 2) form air outlet 52；The second level air duct 5 is vertical with direction of travel Horizontal direction (i.e. x-axis direction) on have horizontal width, and above-mentioned windward side 51 formed arc can make the horizontal width from The air intake vent (the lower section port in the second level air duct 5 i.e. shown in fig. 6, figure in do not indicate) in the second level air duct 5 is big to air outlet 52 Cause equably reduces.For example, the horizontal width at 3 positions, respectively L1, L2 and L3 have illustratively been marked in Fig. 6, it can Know: as the distance between L1, L2 and L3 corresponding position and air outlet 52 are increasingly closer, the width of L1, L2 and L3 are also substantially equal Evenly smaller and smaller, so as to smoothly guide wind to air outlet 52, the generation of greatly less turbulent flow reduces air quantity damage It loses.Wherein, in order to enable windward side 51 meets above-mentioned condition, 51 corresponding camber line (the i.e. windward side of windward side can be made 51 projection in vertical direction) it is helical, such as logatithmic spiral, Archimedes spiral etc., the disclosure is limited not to this System.

Further, as shown in fig. 6, when air outlet 52 is rounded, camber line that above-mentioned windward side 51 is correspondingly formed can be with It is tangential on the circular air outlet 52, enables wind to be smoothly directed to air outlet 52 from windward side 51 is oblique, and spiral in turn It is upwardly into power part 3, helps to reduce wind loss.

In addition, as shown in fig. 6, one can be outwardly formed at cleaning object storage member 2 on the outer wall in second level air duct 5 Protrusion 54 is provided with non-contact inductive co-operating member (not shown) in the protrusion 54, can be matched with cleaning object and receive Receive the non-contact inductive element (not shown) being arranged on component 2.It is possible to pass through non-contact inductive co-operating member With the cooperation between non-contact inductive element, determine whether the cleaning object storage member 2 is assembled to automatic cleaning equipment, Avoid automatic cleaning equipment do not install cleaning object storage member 2 in the case where start, avoid dust enter such as motor or Other internal environments and damage.

For example, when non-contact inductive element is magnetic sheet, non-contact inductive co-operating member can pass for Hall Sensor；Certainly, the disclosure is limited not to this.

2, power part 3 is arranged obliquely

Fig. 7 is the cross-sectional view in a kind of second level air duct and power part shown according to an exemplary embodiment.Such as Fig. 7 It is shown, end formation air outlet 52 of the second level air duct 5 far from cleaning object storage member 2 (being not shown in Fig. 7), and the air outlet 52 are also snap-fit attachment to the air inlet 31 of power part 3.Wherein, plane locating for air outlet 52 intersects with horizontal plane, i.e. air outlet 52 favour horizontal plane；So, when power part 3 is axial flow blower, and shaft (the shaft side of air inlet 31 and the axial flow blower To can be found in the chain-dotted line direction indicated in Fig. 7) it is in the same direction when, effectively appear the axial flow blower and favour horizontal plane placement.

When the plane locating for the air outlet 52 and air inlet 31 is perpendicular to horizontal plane, wind in 5 internal flow of second level air duct and It is essentially all to realize flowing in the horizontal plane, thus wind is by light breeze during entering power part 3 by second level air duct 5 When road 5 is blown into axial flow blower, wind direction is arranged essentially parallel to rotor shaft direction, so as to keep the axial flow blower as power part 3 real Existing maximum transfer efficiency (such as the efficiency for converting electrical energy into wind energy)；And it is flat to work as plane locating for air outlet 52 and air inlet 31 Row when horizontal plane, wind flows along the horizontal plane substantially inside second level air duct 5, but by second level air duct 5 enter power part 3 when, It needs then flows along the vertical direction, so that the transfer efficiency of the axial flow blower as power part 3 is minimum.

However, cannot achieve 31 institute of air outlet 52 and air inlet since the inner space of automated cleaning component is extremely limited Locate plane perpendicular to horizontal plane, so in the technical solution of the disclosure, by increasing the axis stream wind as power part 3 as far as possible Angle between machine and horizontal plane, on the one hand can the inner space to automated cleaning component rationally utilized, on the other hand The transfer efficiency of axial flow blower can be made to maximize as much as possible.

In the technical solution of the disclosure, for flow process of the wind in second level air duct 5, second level air duct 5 can also be made On towards the side wall outwardly convex at air outlet 52 make power to increase inner cavity capacity of the second level air duct 5 at air outlet 52 Energy loss of the wind that component 3 generates at air outlet 52 is lower than default loss.Than as shown in figure 8, when air outlet 52 is located at two It is bottom side towards the side wall at air outlet 52 when the top side in grade air duct 5, thus bulge-structure shown in Fig. 8 can be formed down 53, to increase inner cavity capacity of the second level air duct 5 at air outlet 52, so that wind changes wind direction (in outlet air at air outlet 52 Plane locating for mouthfuls 52 and non-perpendicular to horizontal plane in the case where) and in the case where being blown into power part 3, it is empty to provide bigger buffering Between, to reduce energy loss of the wind at air outlet 52.

Further, it is based on above-mentioned bulge-structure 53, so that wind diagonally descends direction to enter substantially after entering the second level air duct 5 (such as incident for upper left lower right in Fig. 7) is penetrated, then transfers to be emitted obliquely from air outlet 52；Therefore, such as Fig. 7 institute Show, can be connected using cambered surface 55 between the bottom surface and air outlet 52 in the second level air duct 5, so that cleaning object storage member 2 The wind of output can be smoothed the air inlet 31 of guidance to power part 3, to help to reduce wind loss.

As an exemplary embodiment, the cleaning member 1 in the automatic cleaning equipment of the disclosure can be roller brush assembly.Figure 9 show the schematic perspective view of the main brush mould group in roller brush assembly, and Figure 10 is the decomposition texture of main brush mould group shown in Fig. 9 Schematic diagram (visual angle in Figure 10 is to be observed from bottom to top along z-axis)；As shown in figs. 9-10, which may include rolling Brush 11 and round brush storehouse 12, round brush storehouse 12 further comprise floating system bracket 121 and round brush lid 122.

1) round brush 11

Figure 11 shows the structural schematic diagram of round brush 11.As shown in figure 11, the round brush 11 in the roller brush assembly can be glue Hair mixing brush, i.e., in the shaft 111 of round brush 11 simultaneously be provided with glue brush part 112 and hairbrush part 113, can take into account in this way floor, A variety of cleaning ambients such as woollen blanket.The radial base of the adhesive tape of glue brush part 112, the direction of growth of the hairbrush of hairbrush part 113 and shaft 111 This is consistent, and the width base of the hairbrush width of the adhesive tape width of glue brush part 112, hairbrush part 113 and the arrival end 41 in level-one air duct 4 This is consistent；Wherein, intermediate micro- row being bent upwards shown in Figure 11 is a glue brush part 112, in a row of undaform is one A hairbrush part 113 may include at least one glue brush part 112 and at least one hairbrush part 113 on each round brush 11.

Glue brush part 112 and hairbrush part 113 not take the set-up mode being parallel or nearly parallel, but have between the two Biggish angle, to ensure that glue brush part 112 and hairbrush part 113 can respectively realize the application function of itself.

(1) glue brush part 112

Due to existing between the brush tuft 113A on hairbrush part 113 compared with big gap, so that wind is easy to flow between gap It loses, to being formed, the help that vacuum environment is formed is smaller.Therefore, by setting glue brush part 112, effect of going for a drive can be formed, and It and when intensity of going for a drive reaches preset strength, can assist to realize the sweeping to cleaning object, cleaning object is being rolled Under the sweeping of brush 11 and the blowing of wind, more easily it is transported in cleaning object storage member 2.

Wherein, folder of the glue brush part 112 between the setting direction in the cylindrical surface of round brush 11 and the setting direction of shaft 111 Angle is got over hour, for example glue brush part 112 carries out straight line arrangement along the setting direction of shaft 111 completely in the limiting case, i.e., completely When along the x-axis arrangement of embodiment illustrated in fig. 11, glue brush part 112 can form maximum and go for a drive intensity.

And on the basis of in view of intensity of going for a drive not less than above-mentioned preset strength, the disclosure is also further combined with it His factor is considered.Such as in embodiment shown in Figure 11, glue brush part 112 is actually not arranged fully according to straight line, but Using arranging in the cylindrical surface of round brush 11 along close to by the way of straight line, and make the middle position of glue brush part 112 to rolling The rotating direction end bend of brush 11, so that the wind that power part 3 generates converges in glue brush part 112 and forms curved interposition It sets, to can further collect to cleaning object.And on the other hand, the glue brush part 112 of complete lineal layout The maximum that moment can only be obtained is gone for a drive effect, and the setting of certain bending angle can going for a drive the round brush 11 in rolling process Effect is kept for a period of time.

In fact, as shown in Figure 10, by being compared to the level-one air duct 4 for being located at 12 oblique upper of round brush storehouse with round brush 11 Known to: on width direction (or left and right directions), the specification in level-one air duct 4 is less than round brush 11；Wherein, compared with the force one wind of small dimension Road 4 can use limited air quantity and realize bigger static pressure, be delivered to cleaning object storage member 2 convenient for that will clean object, And bigger cleaning area then may be implemented in the round brush 11 of larger specification, so above-mentioned size heterogeneity is actually to be in cleaning The promotion of efficiency and the design means taken.So, reasonable disposition is carried out by the shape to glue brush part 112, so that wind direction glue The middle position of brush part 112 is collected, and above-mentioned size heterogeneity can be matched with, it is ensured that by all cleanings swept by round brush 11 Object is sent into level-one air duct 4, and is further delivered in cleaning object storage member 2.

In addition, as can be seen that floating system bracket 121 has from air inlet (lower end in figure) to level-one air duct 4 in Figure 10 Wind path guides arc structure 1211, and the arc structure 1211 and the arc shape 40 in level-one air duct 4 are that curvature is consistent, thus The arc structure 1211 improves the efficiency that wind enters air duct, reduces wind loss.

(2) hairbrush part 113

In embodiment of the disclosure, hairbrush part 113 is formed between rotor shaft direction larger in the cylindrical surface of round brush 11 The angle of deviation；For each hairbrush part 113, by forming above-mentioned relatively large deviation angle, it can make to form the several of the hairbrush part 113 When brush tuft 113A successively arranges along rotor shaft direction, the bigger angle of coverage to round brush 11 is realized in the circumferential, such as to round brush 11 circumferential angle of coverage reaches predetermined angle.

On the one hand, by expanding the circumferential angle of coverage to round brush 11, cleannes and cleaning efficiency can be promoted.Round brush 11 During scrolling, the cleaning to bottom surface may be implemented；And when hairbrush part 113 reaches the circumferential angle of coverage of round brush 11 At 360 °, it can ensure that round brush 11 can be realized cleaning operation always during scrolling.

Meanwhile by increasing the angle of deviation between hairbrush part 113 and rotor shaft direction, each hairbrush part 113 can be made right The circumferential angle of coverage of round brush 11 increases with it, thus when realizing the circumferential angle of coverage of same size, required hairbrush part 113 quantity is less.For example, it is assumed that need to realize 360 ° of circumferential angle of coverage to round brush 11, if each hairbrush part 113 circumferential angle of coverage is 60 °, then needs 6 hairbrush parts 113, and if the circumferential angle of coverage of each hairbrush part 113 is At 120 °, then 3 hairbrush parts 113 are only needed.It therefore, can be with by increasing the angle of deviation between hairbrush part 113 and rotor shaft direction The setting quantity to hairbrush part 113 is reduced, is facilitated in the case where ensuring cleaning effect, the production cost of round brush 11 is reduced.

On the other hand, hairbrush part 113 is needed to contact ground during cleaning and be cleaned；Wherein, due to hairbrush part 113 Flexible nature, will generate certain deformation in cleaning process, form " support " effect to entire automatic cleaning equipment.That , if hairbrush part 113 is to the circumferential angle of coverage deficiency of round brush 11, will lead to form circumferential covering and cover with not formed circumferential direction Difference in height is formed between the region of lid, automatic cleaning equipment jolting or shake in the z-axis direction is caused, influences clean operation It executes；Therefore, when hairbrush part 113 can be realized 360 ° of circumferential angle of coverage, it can be jolted, be shaken by elimination, thus both It can ensure that automatic cleaning equipment maintains continual and steady output, and can reduce the noise of automatic cleaning equipment generation, also It can cause to impact to avoid to motor, facilitate the service life for extending automatic cleaning equipment.

2) round brush lid 122

In the technical solution of the disclosure, when cleaning member 1 is roller brush assembly, Figure 12 is shown in the roller brush assembly The schematic perspective view of round brush lid 122, the round brush lid 122 may include antiwind guard block 1221 and be located in the direction of travel The flexible glue scraping article 1222 at antiwind 1221 rear of guard block.Antiwind 1221 one side of guard block can stop the cleaning pair of large volume Blocking is formed as entering air duct, on the other hand stops the slender bodies such as electric wire to enter round brush storehouse 12 and generates winding.

In conjunction with Fig. 9 it is found that round brush lid 122 is located at 11 lower section of round brush, the cleaning that specification can be stopped excessive in the z-axis direction Object is involved in inside roller brush assembly, influences normal clean operation.And flexible glue scraping article 1222 is located at antiwind guard block in z-axis 1221 lower section, and flexible glue scraping article 1222 is located at the direction of travel end of round brush 11, the flexible glue scraping article 1222 and round brush on the y axis Certain distance (such as 1.5-3mm) is kept between 11, and by fitting in ground, is allowed to sub-fraction not by round brush 11 The cleaning object directly rolled is intercepted and has been scooped up, so that it be made to be involved in round brush 11 under the sweeping of round brush 11 and the blowing of wind Between round brush storehouse 12, hence into level-one air duct 4.The position of flexible glue scraping article 1222 and the selection of angle are so that cleaning object begins Final position avoids also being left after flexible glue adhesive tape 1222 in optimal cleaning and suction position.

As shown in figure 12, the end of antiwind guard block 1221 in the direction of travel (can be the y axis negative direction of Figure 12, i.e., The right end of antiwind guard block 1221) it can be equipped with the obstacle detouring assistance 1221A for being matched with the direction of travel of automatic cleaning equipment, one Aspect obstacle detouring assistance 1221A can assist automatic cleaning equipment to play the role of obstacle detouring (surmounting obstacles), on the other hand should Obstacle detouring assistance 1221A can be butted on the upper surface of flexible glue scraping article 1222, make the bottom margin of the flexible glue scraping article 1222 automatic Cleaning equipment can fit in surface to be cleaned (such as ground, desktop) always when in running order, and avoid the flexible glue scraping article 1222 are rolled-up due to the barriers such as rubbish in surface to be cleaned, influence subsequent cleaning effect.

In one embodiment, obstacle detouring assistance 1221A can for the end of antiwind guard block 1221 in the direction of travel to Under (i.e. z-axis negative direction shows as " top " in Figure 12) formed protrusion.Figure 13 is that obstacle detouring assistance 1221A is scraped with flexible glue The partial enlargement diagram of matching relationship between item 1222；It as shown in figure 13, can be with as the protrusion of obstacle detouring assistance 1221A It include: the first composition side AA on front side of direction of travel, when the first composition side AA is tilted to direction of travel rear side, such as When the composition of this in Figure 13 first side AA is tilted from left to right, since automatic cleaning equipment carries out forward drive from right to left, thus There are when barrier 6, first composition side AA is matched with above-mentioned suspension system bracket 121, Ji Ke in surface to be cleaned Smooth guide automatic cleaning equipment crosses the barrier 6 during obstacle detouring, without being stuck.

As shown in figure 13, the protrusion as obstacle detouring assistance 1221A may include: second group on rear side of direction of travel Second the upper surface that side BB is butted on flexible glue scraping article 1222 is formed at side BB, and by this；So, when protrusion by first form side AA and When second composition side BB is constituted, which can be tip-angled shape shown in Figure 13.

It should be understood that minimum point should be not less than round brush lid using the obstacle detouring assistance 1221A of convex form 122 minimum end face is avoided being formed with surface to be cleaned and scratches and generate additional thus in the walking process of automatic cleaning equipment Resistance, facilitate promoted automatic cleaning equipment cleaning efficiency.

3) floating system bracket 121

Therefore, when automatic cleaning equipment is in normal cleaning process, floating bracket 1213 rotates under the influence of gravity To extreme lower position, no matter in floor, carpet or other rough clean surfaces, in the floating path domain of round brush 11, The round brush 11 installed in the floating system bracket 121 can be tightly attached to surface to be cleaned, with realize peak efficiency patch clean, All there is preferable patch ground effect in different type clean surface, the leakproofness in air duct is contributed obvious.

And when in surface to be cleaned there are when barrier 6, by floating bracket 1213 up and down " floating ", round brush can be reduced The 11 equal interactions between barrier 6, so that automatic cleaning equipment be assisted easily to realize obstacle detouring.Wherein, 4, level-one air duct Between fixed bracket 1212 and floating bracket 1213, thus the round brush 11 to float proposes flexible demand to level-one air duct 4, because The floating variation of round brush 11 can not be absorbed for the air duct of rigidity, which is realized by the flexible material in level-one air duct 4；So when Level-one air duct 4 can squeeze one by floating bracket 1213 during obstacle detouring using when such as flexible glue flexible material is made Grade air duct 4 and make its generate deformation, thus smoothly realize upwards " floating ".

In addition, for the surface to be cleaned of the rough surfaces such as carpet, passing through floating bracket 1213 in normal cleaning process " floating " effect, it is possible to reduce interfering between round brush 11 etc. and carpet, to reduce what round brush motor 1214 was subject to Resistance facilitates the power consumption for reducing round brush motor 1214, and prolongs its service life.

4, the structure in level-one air duct 4

In the technical solution of the disclosure, by the guiding function in level-one air duct 4, so that the wind that power part 3 generates can Object is cleaned with the dust etc. for cleaning cleaning member 1 to be delivered in cleaning object storage member 2.

For overall structure, as shown in figure 15, level-one air duct 4 can be in the shape of a trumpet, and any place on level-one air duct 4 Corresponding sectional area reverse phase is about the spacing distance between any place and cleaning member 1；In other words, " horn mouth " relatively Object storage member 2 is cleaned towards cleaning member 1, relatively small side direction in big side.

In this embodiment, by the bell mouth shape for being configured to gradually successively decrease by the sectional area in level-one air duct 4, so that accordingly Static pressure at position is incremented by therewith, that is, forms increasing suction；So, when the cleaning object such as dust, rubbish is cleaned Component 1 sweeps and after band to level-one air duct 4, as cleaning object moves away from cleaning member 1, gradually close to cleaning object storage Component 2 (equally gradually close to power part 3), although cleaning member 1 is gradually reduced to the sweeping power that cleaning object applies, by It is gradually increased in power part 3 to the suction that cleaning object applies, is attracted and is delivered to clearly so as to ensure to clean object In clean object storage member 2.

Further, when cleaning member 1 is roller brush assembly, as shown in figure 15, the arrival end in level-one air duct 4 is towards round brush The round brush 11 of component, and the width on the direction (i.e. x-axis direction) vertical with direction of travel in the horizontal plane of arrival end 41 from It is upper to be incremented by downwards.In order to make it easy to understand, for the matching relationship between level-one air duct 4 shown in figure 15 and round brush 11, Figure 16 shows Level-one air duct 4 and the mutually matched schematic perspective view of round brush 11 are gone out.As shown in figure 16, close to round brush on level-one air duct 4 11 arrival end 41 is with larger sectional area, the outlet end 42 far from round brush 11 with small cross sections product.Wherein, it is based on arrival end 41 above-mentioned " incremental " feature, the section of the arrival end 41 can be trapezoidal, and the second relatively narrow edge 412 is trapezoidal upper bottom Side, wider first edge 411 are trapezoidal bottom；Certainly, as long as meeting above-mentioned " incremental " feature, the section of arrival end 41 Other shapes can also be used, for example, correspond to above-mentioned two " trapezoidal " waists can using arc etc., the disclosure not to this into Row limitation.

In this embodiment, by meeting above-mentioned " pass using trapezoidal or similar at the arrival end 41 in level-one air duct 4 The shape of increasing " feature, so that the static pressure of corresponding position is incremented by therewith, then when the cleaning object such as dust, rubbish is by round brush When 11 sweepings and band to arrival end 41, the wind that power part 3 generates is capable of providing enough suction, so that being swept to arrival end 41 Cleaning object can be inhaled into as much as possible cleaning object storage member 2 in, facilitate promoted cleaning efficiency.

As shown in figure 15, the arrival end 41 in level-one air duct 4 can connect to the round brush of the roller brush assembly as cleaning member 1 Storehouse 12, and pass through the opening on the round brush storehouse 12 towards round brush 11；Wherein, as shown in figure 17, level-one air duct 4 is in round brush 11 It include two side walls on rotating direction: the first side wall 43 positioned at the rear side of direction of travel, the positioned at the front side of direction of travel Two side walls 44, the two can be configured by following manner.

1) the first side wall 43

In one embodiment, the first side wall 43 can be arranged along the tangential direction of the circular cross-sectional area in round brush storehouse 12.Than As shown in figure 17, round brush storehouse 12 may include the left side multiple portions such as arcuate structure and right side L-type structure on section, wherein Arch section in the arcuate structure of left side corresponds to circular dashed line region shown in Figure 17, thus the corresponding circle of the arch section Shape dashed region can be equivalent to above-mentioned circular cross-sectional area；Correspondingly, the first side wall 43 in level-one air duct 4 can be along the circle The tangential direction of shape dashed region is arranged, such as in the relative positional relationship shown in Figure 17, since level-one air duct 4 is located at round brush The oblique upper of component and the rear for being biased to round brush 11 in the direction of travel, thus the first side wall 43 can be arranged along the vertical direction.

In this embodiment, after round brush 11 sweeps cleaning object from ground, object is cleaned first along round brush 11 and round brush Gap movement between storehouse 12；And with movement of the cleaning object from roller brushes structure to level-one air duct 4, by by the first side wall 43 are arranged along above-mentioned tangential direction, so that the flowing of the motion profile and wind direction of cleaning object not will receive the first side wall 43 Stop, it is ensured that cleaning object passes through level-one air duct 4 and enters in cleaning object storage member 2.

2) second sidewall 44

In one embodiment, in conjunction with Figure 15 and Figure 17, when cleaning member 1 is roller brush assembly, and level-one air duct 4 is in traveling side Upwards when being partial to the rear of round brush 1, the arrival end 41 in level-one air duct 4 is towards front side (such as the left side in Figure 15 of direction of travel Side) round brush 11 at obliquely downward, outlet end 42 be connected at rear side (such as right side in Figure 15) oblique upper of direction of travel The air intake vent 21 of object storage member 2 is cleaned, and the air outlet 22 for cleaning object storage member 2 is located at non-top sides (i.e. outlet air Mouth 22 is not located at top side 23, for example is located at right side wall in Figure 15).

Wherein, the second sidewall 44 in level-one air duct 4 is towards the oblique rear-inclined of horizontal plane (i.e. as close possible to horizontal plane), namely Form second sidewall 44 and z-axis vertical direction angle as big as possible.In fact, due to the inner space of automatic cleaning equipment It is limited, cause the setting between roller brushes structure, level-one air duct 4 and cleaning object storage member 2 etc. extremely compact, and most save empty Between mode be by level-one air duct 4 completely along z-axis be arranged, but that can significantly lose air quantity, to substantially reduce suction efficiency；And In embodiment of the disclosure, under the conditions of limited inner space, by increasing the angle between the first side wall 43 and z-axis, Wind direction can be done and be guided obliquely, it is anti-with 23 wide-angle of inner wall top side after so that wind is entered the inside of cleaning object storage member 2 After penetrating, horizontal direction discharge, a this wide-angle reflection are approached by the strainer (not indicating in figure) at air outlet 22 Wind path design to the loss very little of air quantity.And in the related art, in order to save space and use completely by wind straight up When derived wind path, due to wind straight up meet with turn mouth the result is that by being reflected down, thus air quantity can impact upwards It is largely lost at mouth in turning for guiding horizontal afterwards.It on the other hand, can be to avoid automatic by avoiding straight up exporting wind It the moment that cleaning equipment is shut down, causes to drop out still in the cleaning object in level-one air duct 4 to the external world, causes the second level to ground Pollution.

Also, since the arrival end in level-one air duct 4 41 is connected to cleaning object towards the round brush 11 of lower left, outlet end 42 The air intake vent 21 of storage member 2, thus level-one air duct 4 by wind guide to cleaning 2 inside of object storage member when, can make wind and Its cleaning object swept along directly blows to the inner wall top side 23 of cleaning object storage member 2；And since wind is directly blowing to top side When 23, clean the air outlet 22 of object storage member 2 not at the top side 23 at, thus need to occur at top side 23 big The reflection of incidence angle, convert wind direction after by air outlet 22 enter second level air duct 5；Wind enters section after cleaning object storage member 2 Product becomes larger, and leads to the decline of wind speed, cleans object and falls due to wind speed decreased and from top side 23, to reside in cleaning object In storage member 2；Simultaneously as the change of wind speed decreased and wind direction, goes forward side by side so while wind itself can blow to air outlet 22 Enter second level air duct 5, but can not continue that object will be cleaned blows at air outlet 22, thus when cleaning object storage member 2 is dirt When being provided with strainer 24 at case assembly and air outlet 22, it can be directly blown to 24 surface of strainer to avoid cleaning object, prevented clear Clean object causes to block to the surface of strainer 24, helps to promote air quantity utilization rate.

In addition, as shown in figure 18, which is equipped with inlet air when cleaning object storage member 2 is dirt case assembly The side wall 25 of mouth 21 is detachable, and when the side wall 25 is removed, can be formed for toppling over the cleaning pair stored in dirt case assembly The pour spout 26 of elephant.Since air intake vent 21 is set on side wall 25, thus the specification of side wall 25 is naturally larger than air intake vent 21, so After dismantling side wall 25, the pour spout 26 that specification is greater than air intake vent 21 can be formed, convenient for user to collecting in dirt box structure The cleaning object such as dust is toppled over.

5, complete machine air duct is hermetically sealed

From the analysis of front it is found that vacuum degree and air quantity have significant contribution similarly for high suction efficiency.In the disclosure Technical solution in, processing is all sealed to the place of having the gap existing for component each in wind path structure junction, for example stitching Flexible glue etc. is filled at gap, to avoid leaking out, namely reduces the loss of vacuum degree.On the other hand, as shown in figure 5, in blower Flexible glue part 32 is used at air outlet, wind is all exported into host, the use of flexible glue part 32 to avoid leaking out in addition to (can reduce true Reciprocal of duty cycle) outside, dust can also be avoided to enter the motor etc. inside automatic cleaning equipment, help to extend automatic cleaning equipment Service life.

Those skilled in the art will readily occur to its of the disclosure after considering specification and practicing disclosure disclosed herein Its embodiment.This application is intended to cover any variations, uses, or adaptations of the disclosure, these modifications, purposes or Person's adaptive change follows the general principles of this disclosure and including the undocumented common knowledge in the art of the disclosure Or conventional techniques.The description and examples are only to be considered as illustrative, and the true scope and spirit of the disclosure are by following Claim is pointed out.
