Description

Sweeping robot

Technical field

The innovation is related to a kind of a kind of motor-driven machinery more particularly to built-in robot of dust catcher and sweep brush of sweeping the floor.

Background technology

Sweeping robot essence, is the intelligent carriage of dust catcher and sweep brush built in one, it is self-service that operation finishes trolley Storage charges, and typical product is for example：" precious " of " roomba " of U.S.'s IROBOT brands and Chinese section Butterworth brand.They Shared shortcoming be：Dust box very little, is finished to remove by hand and empties dust, and needs periodically to be cleared up with hairbrush internal.This Sample causes to bend over and wash one's hands, and to cover nose or wear masks.There is the user of allergic rhinitis especially without love.

With another external dust catcher, the dust suck-back in dust box is come out（Abbreviation suck-back）This can be overcome difficult. " Butterworth robot of section science and technology（Suzhou）Two patents of Co., Ltd "《CN201010149846- robot systems》With 《CN201210516561- cleaning systems and suction apparatus for ash》It is related to the suck-back technology, but its scheme is very complicated.

In view of most users, in purchase sweeping robot（It is hereinafter referred to as precious）Before, a common suction has been possessed Dirt device（Hereinafter referred to as external dust catcher）, such as " Philip FC5982 ".This case is intended to the precious dust box in existing ground and charging Stake（Namely garage）It is improved, allows precious and existing dust catcher organic assembling, realize suck-back.

The content of the invention

List of figuresthe：

Before Fig. 1 is robot storage, when Fig. 2 is the suck-back after robot is put in storage, Fig. 3 is charging pile namely garage, and Fig. 4 is ash During dirt box suck-back, side section when Fig. 5 is dust box suck-back, Fig. 6 is oblique profile when dust box is ordinary.

Indicate inventory and its explanation：

100 partition plates：Dust box is separated into small one and large one two spaces by it after the overturning of 102 shafts；The lower edge of partition plate is brush Hair or flexible glue, when partition plate is overturn, are equivalent to besom, and the dust in box is cleaned compression；

101 sieves：It is acted on, first, screening out the big sundries of height, such as peel and paper etc. avoids blocking pipeline；Second is that conduct Reinforcing rib reinforces partition plate；

102 shafts：Partition plate 100 is overturn around this；If this axis sinks, the exposed parts of partition plate are reduced, it can be achieved that partition plate 100 is overturn Afterwards, dust box upper surface remains unchanged smooth no protrusion；The shaft can arrange in pairs or groups spring, and 100 partition plates are subject to turn over when outer tunnel negative pressure Turn, negative pressure is rebounded when disappearing, closing outlet.

110 strainers：" extra large pa " is commonly called as, is usually made of sponge, outside is motor and fan；This strainer is disassembled Afterwards, also allow for toppling over dust manually.

111 entrances：High-speed flow inclusion of dirt enters from this mouth, collects towards 110 strainers；

210 flat mouthes：It is made of duroplasts such as ABS, effect is from rounded transitional into flat by passage.

212 soft lips：It is made of transparent silica gel or PVC flexible plastics, outside shaped like loudspeaker, end 213 is used as sealant rubber ring, has Beneficial to identical.Under negative pressure, meeting collapse-deformation, this deformation is conducive to reduce the cross section of pipeline to the soft lip.In order to rule its Favourable deformation, outer surface have the embossment of became uneven.Favourable deformation refers to：Even if robot storage posture is slightly inclined Move, flat mouth 210 under the auxiliary of this deformation, also can respective offsets, with the interface of face dust box；

213 cushion rubbers：Be conducive to coincide as sealant rubber ring；

211 interfaces：231 interfaces are connected by hose, form gas channel.

231 interfaces：211 interfaces are connected by hose, form gas channel.

233 interfaces：With 231 orifices, the tracheae of external dust catcher is docked with this, is the end of the whole gas channel in garage Bring out mouth.

200 cover boards：It is formed by transparent acrylic bending right angle, there is shaft 201 in bending place, and lower end is hit by robot After hitting, overturning covers robot；

201 shafts：The shaft can have spring, and cover board 200 is allowed to turn over before storage, robot is not interfered to be put in storage, if this shaft is not set If putting spring, then, the fastening spring hose between interface 211 and interface 231 by the pulling force of hose, can play identical Effect；

230 charging piles：Plug can be inserted into herein, is connected with garage circuit, allow garage control by namely garage, external dust catcher The work of the external dust catcher of system；

232 pedestals：The pedestal of 230 charging piles, the charging interface of robot are usually located at herein；

240 vehicle bodies：The body of robot.

Specific implementation method：

Dust collects after entering from the entrance 111 of dust box, and at this time as shown in fig. 6, partition plate 100 is horizontal, only there are one empty in box Between.

When robot is put in storage, as shown in figure 3, cover board 200 is upturned under the spring effect of shaft 201, do not interfere It is put in storage.Subsequent robot head hits the lower end of cover board 200, and forcing cover board 200,201 overturnings cover robot top around the shaft Portion, state are as shown in Figure 2.Because external dust catcher plug is inserted on garage, circuit is by garage control, external dust catcher this moment Start and generate negative pressure.As shown in figure 5, partition plate 100 offsets the spring force of its shaft 102 under suction function, 102 turn over around the shaft Turn, at the same time, two spaces are separated out by partition plate 100 in dust box, dust is swept to the sky close to strainer 110 by partition plate 100 Between.As shown in Fig. 2, soft lip 212 coincide with dust box this moment, and it is bonded under negative pressure closer, negative pressure makes soft lip 212 collapse It collapses deformation, hard mouth 210 is allowed to form complete gas channel this moment closer to dust box.

It is mingled with the air-flow of dust, through sieve 101, into soft lip 212, the pipe between approach interface 211 and interface 231 Road, using interface 233 and the pipeline of external dust catcher, into external dust catcher.

When external dust catcher is shut down, negative pressure disappears.Partition plate 100 recovers horizontal position under the spring effect of its shaft 102 It puts.

This case is summarized：

The size of dust catcher suction is bullied the influences of channel cross-sections, and passage is narrower, and suction is stronger；Cross section is more uniform, effect Fruit is better.This case cleverly realizes slype using the overturning of partition plate 100, enhances suction, and simple in structure, reliability By force.

Soft lip 212 can not only realize that sealing coincide with its simple structure, but also can deform torsion under negative pressure, realization air-flow Channel cross-section it is uniform.

The docking that cover board 200 realizes the trigger action and passage of suck-back with its succinct structure coincide.

The structure of the innovation is simple, and reliability is high, breaks traditional technology prejudice, realizes better suck-back effect.

It is further to improve：

Such as " Xiaomi Technology Co., Ltd. "《CN201520228604- is used for the dust-collecting box and cleaner of clean robot Device people》In a case, technical solution it is complicated, to solve the problems, such as be：Because dust box is compact, to realize to dust Compression.Partition plate 100 in this case can be achieved with the compression to dust by often overturning.

The trigger mechanism that partition plate 100 is often overturn：An air bag A is fastened in robot head bumper, then in ash An air bag B is fastened between dirt box internal partition 100 and dust box, the two air bags are connected using hose.Robot is cleaning work During industry, head bumper constantly hits wall, and air bag A compresses under shock, and compressed air forces air bag B to expand, so as to The effect of gas-pressure mandril is played, partition plate 100 is allowed constantly to overturn, dust is compressed.
