Below, have the embodiment of the electric dust collector of the cleaner head that the present invention relates to reference to description of drawings.
[first embodiment]
In Fig. 1, label 1 expression electric dust collector body, it is provided with electric blower 3, and this electric blower 3 is used to make and is formed at the intrinsic dust storage chamber 2 of described electric dust collector and forms negative pressure, is provided with dust-collecting filter 4 in dust storage chamber 2.Label 5 is flexible pipes that the one end connects with electric dust collector body 1 removably, is provided with hand-held pipe 6 at the other end of this flexible pipe 5.This hand-held pipe 6 is provided with handle portion 6A and operating portion 6B, is provided with closing switch S 1 and being used to set configuration switch S2, the S3 etc. of the power of electric blower 3 of the power supply that is used to cut off electric blower 3 at operating portion 6B place.
Prolong pipe 7 and be connected with hand-held pipe 6 removably, the tube connector 11 of cleaner head 9 is connected with the front end that prolongs pipe 7 removably.
As shown in Figure 2, cleaner head 9 comprises suction inlet body 10 and the tube connector 11 that is arranged on these suction inlet body 10 rear portions.Described suction inlet body 10 has the lower house 10b that cross section is hemispheric upper shell 10a and is installed on this upper shell 10a bottom.Be formed with as shown in Figure 3 control of dust in the bottom of lower house 10b with opening 12.Be provided with and manage 7 tube connectors of taking apart 11 with prolongation at the tube portion 10c place at suction inlet body 10 rear portions.Label 17 expressions are arranged at the roller on the lower house 10b.
Be formed with suction chamber R in suction inlet body 10 inside, close opening 12 places in this suction chamber R are provided with the rotary cleaning body 13 that extends along the left and right sides width of suction inlet body 10.This rotary cleaning body 13 is that ground FL scrapes and gets dust or dirt by rotation to be cleaned.The opening 12 of lower house 10b has and the corresponding shape of the appearance and size of rotary cleaning body 13.In addition, is supporting with the not shown bearing that rotation mode freely is set on the suction inlet body 10 two ends of rotary cleaning body 13, and the length that comprises the rotary cleaning body 13 of two ends equates with the left and right sides width of suction inlet body 10 basically.
Rotary cleaning body 13 has and is used for wiping ground FL and extends straight a plurality of scraping blades 14 to two ends, left and right sides places, as shown in Figure 5, anterior 10F place at upper shell 10a offers air introducing port 15, the scraping blade 14 that this air introducing port 15 is used to keep watch and gives rotary cleaning body 13, thus make rotary cleaning body 13 rotations.
Inboard at the suction inlet body 10 of air introducing port 15 is formed with guide wall 15a, and this guide wall 15a is used to keep watch and gives scraping blade 14 expeditiously.As shown in Figure 4, the A/F of this air introducing port 15 is equivalent to the left and right sides width of scraping blade 14, and equals the left and right sides width of opening 12, thereby can make air along whole width range piping and druming scraping blade 14.
The cross section of scraping blade 14 is circular-arc, and its top when air piping and druming scraping blade 14, can make rotary cleaning body 13 (in Fig. 2) rotation in the counterclockwise direction towards the rear of direction of rotation.
If the top 14b of scraping blade 14 is positioned at the rear with respect to direction of rotation of root 14a, then the cross section of scraping blade 14 is also with type substantially linearly.In addition, though scraping blade 14 can form and be installed on the hard axle core 16 by having the flexible elastomer of similar synthetic rubber,, this scraping blade 14 also can be by soft, as to have wearability plastics and the integrally formed parts of axle core 16.
Because scraping blade 14 bends to circular-arc, so that its side side-prominent in advance, that to be it relative with air introducing port 15 along direction of rotation is recessed, like this, when running into ground, it is easy to produce flexural deformation, but, owing to the piping and druming effect of the air that enters from air introducing port 15, this scraping blade 14 is difficult to produce flexural deformations, thereby can make rotary cleaning body 13 rotations reliably.
The following describes the action of above-mentioned electric dust collector.
As shown in Figure 1, at first, flexible pipe 5 is connected with electric dust collector body 1, and will prolongs pipe 7 and be connected, cleaner head 9 and this prolongation are managed 7 be connected with this flexible pipe 5.Afterwards, when pressing switch S 1 or switch S 2, electric blower 3 makes dust storage chamber 2 be negative pressure state by the power work of setting.This negative pressure is passed through flexible pipe 5, is prolonged pipe 7 and tube connector 11, thereby makes the suction chamber R in the cleaner head 9 be in negative pressure state, sucks air from opening 12 and introducing port 15.
In the time of on suction inlet body 10 being placed on ground FL, because the effect of roller 17, can form narrower gap 18 between ground FL and the lower house 10b, air is drawn through and into opening 12 from this gap 18, but because above-mentioned gap 18 is narrower, the air that imports from air introducing port 15 increases, and the pressure of delivering to the wind on the scraping blade 14 of rotary cleaning body 13 strengthens, thereby rotary cleaning body 13 begins rotation.
Then, because the left and right sides width of air introducing port 15 is equivalent to the left and right sides width of scraping blade 14, scraping blade 14 areas that are subjected to from the air piping and druming of air introducing port 15 have been enlarged like this, in addition, because the vertical height in the edge of air introducing port 15 is narrower, the flow velocity of the air that blows from air introducing port 15 becomes higher like this.Therefore, blow and beat scraping blade 14 fiercely, thereby can make rotary cleaning body 13 rotations reliably from the air that air introducing port 15 blows.So, make 13 couples of ground FL of rotary cleaning body carry out the wiping cleaning by above-mentioned rotation.
When ground FL is flannelette blanket, opening 12 is in the state that is blocked by ground FL, and its result is because the air that imports from air introducing port 15 further increases, the pressure of the wind of piping and druming scraping blade 14 strengthens once more, and the revolving force of rotary cleaning body 13 further increases like this.That is, when ground more needs to scrape the flannelette blanket of action in scraping blade 14 generations, can further improve the revolving force of rotary cleaning body 13.
With scraping blade 14 scrape dust through tube connector 11, prolong pipe 7, flexible pipe 5 and attracted in the dust-collecting filter 4 of body of dust collector 1.
When suction inlet body 10 built on stilts FL, because the air pressure among the suction chamber R equates that with atmospheric pressure so the aspiration of 15 pairs of air of air introducing port reduces, rotary cleaning body 13 stops the rotation or rotary speed reduces.In addition, when rotary cleaning body 13 rotations, because the top 14b of scraping blade 14 is towards the rear of direction of rotation, like this, compare when standing upright on the radius of turn direction, enlarged the contact area that scraping blade 14 contacts with ground FL, thereby can improve dust collecting effect or scrape effect from axle core 16.
In addition, according to this first embodiment, owing to all be to make rotary cleaning body 13 by the equidirectional rotation, so can improve the revolving force of rotary cleaning body 13 from the air of opening 12 suction with from the effect of the air of air introducing port 15 suctions.That is, can improve the rotatory power of rotary cleaning body 13.
As mentioned above,, make rotary cleaning body produce the hair-dryer or the motor of rotation so needn't be provided with to be exclusively used in because rotary cleaning body 13 rotates under the effect of the air that the scraping blade 14 of scraping dust is blown and beaten, therefore, the cleaner head that can provide in light weight, volume is little.
In addition, because suction inlet body 10 is provided with air introducing port 15, from these air introducing port 15 suction suction inlet bodies 10 extraneous air on every side, and the suction wind by this suction makes rotary cleaning body 13 rotations, so its structure is very simple, therefore, can provide cost low cleaner head 9 and electric dust collector.
Fig. 6 and Fig. 7 represent another routine cleaner head 40, are provided with recess 41 in the bottom surface, front side of the lower house 10b of this cleaner head 40, form air introducing port 42 by this recess 41.Label 43 expression guide wall.
In addition, the periphery of suction inlet body 10 is equipped with crashproof retaining 44, and the front side portion 44A of this crashproof retaining 44 protrudes in the place ahead of air introducing port 42.When cleaning, utilize the front side portion 44A of this crashproof retaining 44 can prevent that wall K from blocking air introducing port 42 near wall K.
If adopt such cleaner head 40, then identical with aforesaid way, not only can improve the revolving force of rotary cleaning body 13, can also aspirate the dust that is positioned at suction inlet body 10 the place aheads.
The cleaner head 45 of Fig. 8 and the another example of 9 expressions.This cleaner head 45 is provided with air introducing port 46,46 in the both sides, rear portion of upper shell 10a.Label 47 expression guide wall.Owing to all make rotary cleaning body 13 according to identical direction rotation, so also can improve the revolving force of rotary cleaning body 13 with the air that aspirates from air introducing port 46,46 from the air of opening 12 suctions.
[second embodiment]
Figure 10 and Figure 11 represent the cleaner head 50 of second embodiment, and this cleaner head 50 comprises suction inlet body 20 and tube connector 25.
This suction inlet body 20 comprises upper shell 21 and is installed on the lower house 22 of this upper shell 21.Be formed with air introducing port 34 in the front side of upper shell 21.On lower house 22, be formed with control of dust opening 23.Tube portion 24 places at suction inlet body 20 rear portions, be provided with can with prolong the tube connector 25 that pipe is taken apart.
Be formed with suction chamber 26 in the inside of suction inlet body 20,, be provided with the rotary cleaning body 27 that extends along the left and right sides width of suction inlet body 20 at close opening 23 places of suction chamber 26.This rotary cleaning body 27 by rotation on one side to be cleaned, be that ground 28 is scraped and got dust or dirt, Yi Bian collect dust.The shape of the opening 23 of lower house 22 is corresponding with the flat shape of rotary cleaning body 27.In addition, the length on the left and right sides width of rotary cleaning body 27 is identical with first embodiment.
Rotary cleaning body 27 comprises the tube portion 32 that a core 29, scraping blade 30 and blade 31 are integrally formed.The scraping blade 30 on wiping ground 28 and blade 31 with interlace mode with tube portion 32 in aggregates, tube portion 32 be fixedly installed in a core 29 around.By scraping blade 30 and blade 31 are formed on the one with a portion 32, it easily is fixed on the core 29, be subjected to air effect and the revolving force that produces directly becomes the revolving force of scraping blade 30 with blade 31 constantly.
The shape of scraping blade 30 is identical with scraping blade 14 among first embodiment.In addition, scraping blade 30 along the length of radius of turn direction length along the radius of turn direction greater than blade 31, the length of blade 31 is configured to make its top can be from the opening 23 of lower house 22 with ground 28 contacted length.
As shown in figure 11, on scraping blade 30, be formed with for example opening 33 of rectangle.This opening 33 is used to make the air piping and druming blade 31 that imports from the air introducing port 34 of the front wall portion of upper shell 21 and this blade 31 is applied revolving force.
Scraping blade 30 is by forming than blade 31 more flexible materials, so can be because of the wiping ground 28 easily that bends when scraping blade 30 is run into ground 28.Blade 31 and tube portion 32 are formed by hard material.The thickness of blade 31 is greater than the thickness of scraping blade 31, and its hardness is greater than the hardness of scraping blade 30.The material of scraping blade 30 is identical with first embodiment.The material of blade 31 for example can use PP resin or ABS resin etc.
When scraping blade 30 is different with the material of blade 31 and tube portion 32, it is whole for they are formed, for example after forming tube portion 32 and blade 31 with hard resin, the assembly that is made of tube portion 32 and blade 31 is positioned over inlays in the shaping dies, form scraping blade 30 then.When forming tube portion 32 and blade 31, also can around tube portion 32, form the protuberance that fixedly mounts scraping blade 30 integratedly in advance.In addition, when forming scraping blade 30 and blade 31, also can increase the thickness of blade 31, thereby make this blade 31 than scraping blade 30 more difficult bendings with identical materials.
The opening 33 that is formed at scraping blade 30 is positioned on the path of the 27 air-flow B that are involved in from air introducing port 34 towards rotary cleaning body, and, can make air piping and druming expeditiously on blade 31.Be formed with tubular guide wall 35 in the outside of air introducing port 34.The guide wall 35 of this air introducing port 34 can transmit air along the direction of rotation A of rotary cleaning body 27, and imports air from the rear of the blade 31 of rotation towards rotation the place ahead one side.In addition, in the present embodiment, because the direction axial and guide wall 35 of tube portion 24 is basic identical, and air introducing port 34 be positioned at the cross section of a portion 24 inner or its near, so, be inhaled in the portion 24, therefore from air introducing port 34 inhaled airs along straight line, the wind path resistance is little, and has improved from the pumping efficiency of air introducing port 34 inhaled airs.
Identical with first embodiment, the same length along left and right directions of length on the left and right directions of described air introducing port 34 and scraping blade 30.
According to above-mentioned second embodiment, make and do not damage flannelette blanket etc. because scraping blade 30 easily produces flexural deformations, and blade 31 has higher hardness, so, can improve the revolving force of rotary cleaning body 27.Therefore, the effect that scrapes that improves dust under the situation of flannelette blanket etc. can not damaged.In addition, because rotary cleaning body 27 is (among Figure 10) rotation along clockwise direction, so when suction inlet body 20 advances mobile (left in Figure 10 is to moving), the relative moving speed with respect to ground 28 of scraping blade 30 is bigger, therefore, can make scraping blade 30 scrape flannelette blanket etc. on more consumingly, thus can improve scraping blade 30 on scrape efficient.
In addition, owing on scraping blade 30, be formed with opening 33, so, even be blown to scraping blade 30 from air introducing port 34 inhaled airs, this air still can be blown and beaten blade 31 by described opening 33, therefore, can prevent that scraping blade 30 from can not obtain sufficient revolving force because of the effect generation flexural deformation of described air.Therefore, from air introducing port 34 inhaled airs rotary cleaning body 27 is rotated expeditiously.
Figure 12 represents another routine cleaner head 60.This cleaner head 60 makes scraping blade 61 have the function of blade, and rotary cleaning body 62 is rotated in a clockwise direction, and other parts are identical with second embodiment, so omit its explanation.
[the 3rd embodiment]
Figure 13~Figure 16 represents the cleaner head 70 of the 3rd embodiment.As shown in figure 17, this cleaner head 70 has rotary cleaning body 71.This rotary cleaning body 71 has a plurality of scraping blades 72, and the structure of this rotary cleaning body 71 and shown in Figure 12 identical is so omit its explanation.
The body 73 of this cleaner head 70 comprises upper shell 74 and is installed on the lower house 22 of this upper shell 74, is formed with air introducing port 75,76 in the left and right sides of the front side of upper shell 74.The height that forms this air introducing port 75,76 is different mutually, has difference in height L.
According to this embodiment, can be according to the anglec of rotation of rotary cleaning body 71, scraping blade 72 parts that the wind that change blows from air introducing port 75,76 is blown and beaten.That is, the wind that air introducing port 76 is blowed is arranged in the left part (Figure 15) of scraping blade 72B, and when this scraping blade 72B was positioned at the position of scraping blade 72A, the wind that air introducing port 75 is blowed was positioned at the right side part of scraping blade 72B.
When adopting aforesaid way, the fluctuation of rotary speed is reduced, thereby rotary cleaning body 71 is rotated reposefully.
When rotary cleaning body 71 for example turned over angle [alpha], scraping blade 72B moved to the position of the scraping blade 72A shown in the solid line from the position of solid line, and when rotary cleaning body 71 turned over angle [alpha]/2, scraping blade 72B moved to the position of the scraping blade 72B shown in the dotted line from solid line position.Be under the situation of sustained height at air introducing port 76 and air introducing port 75, when rotary cleaning body 71 turn over α/2 jiao and make scraping blade 72B from solid line position when dotted line position moves, the air that blows from air introducing port 75,76 pushes back scraping blade 72B (bear and make it to the power of rotation counterclockwise).Therefore, the revolving force of rotary cleaning body 71 sharply reduces, thereby produces bigger noise.This moment, the revolving force of rotary cleaning body 71 was minimum.
Be under the situation of sustained height at air introducing port 76 and air introducing port 75, when the scraping blade 72A of rotary cleaning body 71 is positioned at solid line position, the blast of the air that blows from air introducing port 75,76 that scraping blade 72 bears reaches maximum, then rotary cleaning body 71 obtained revolving force F simultaneously from two air introducing ports 75,76 when revolving the α angle, and this revolving force F is a maximum.
That is, rotary cleaning body 71 just bore once maximum revolving force whenever revolving the α angle in rotary course, and the difference of this maximum revolving force and minimum revolving force is bigger.That is, because the fluctuation of revolving force is bigger, and rotary cleaning body 71 just bears revolving force one time whenever turning over the α angle in rotary course, so, rotary cleaning body 71 is rotated reposefully.Therefore, can produce vibration and noise.
Corresponding, under the different situation of the height of air introducing port 75,76, rotary cleaning body 71 just obtains the revolving force of a F/2 when the angle beta that turns over less than the α angle, thereby reduces the poor of maximum revolving force and minimum revolving force.Promptly, because the fluctuation of revolving force diminishes, and rotary cleaning body 71 just bears small rotation power F/2 one time when the angle beta that turns over less than the α angle in rotary course, therefore, rotary cleaning body 71 is rotated reposefully, can also with the vibration and noise control in less degree.In addition, because the air that blows from air introducing port 75,76 impacts different scraping blades 72 at every turn, so the impact noise that described air produces is less.
Figure 18 represent another routine cleaner head 70 ', this cleaner head 70 ' be provided with rotary cleaning body 27 is to replace rotary cleaning body 71.
Be provided with an air introducing port 78 that extends along left and right directions in the upper shell 74 that Figure 19 represents the cleaner head 70 of another example "; in this cleaner head 70 ", with 2 the air introducing ports 75,76 that replace being provided with in upper shell 74, the height of two end 78A, 78B of described air introducing port 78 is different.In addition, cleaner head 70 " comprises rotary cleaning body 71 or rotary cleaning body 27.
