Description
Technical field
The present invention relates to dust catcher, in more detail, relate to vacuum cleaner.
Background technology
Vacuum cleaner, refers to that air amount goes out the device of the foreign matters such as dust afterwards in the inner screen of body.Generally speaking, vacuum cleaner comprises: body, the built-in fan electromotor for generation of inhalation power; Suction nozzle, for from ground aspirated foreign body and air; And dust collect plant, for sifting out foreign matter.In this manual, for convenience of explanation, vacuum cleaner is called to dust catcher.
In general,, according to cleaning environment or user's cleaning custom, can provide the dust catcher of variform.
Aspect the more wide space of stronger inhalation power cleaning, be applicable to using vertical (up-right) dust catcher and horizontal (canister) dust catcher, and cleaning easily aspect narrow space, be applicable to using stick vacuums.And, aspect the wide space of automatic cleaning, be applicable to using robot cleaner.
In order to clean, dust catcher needs mobile., need to carry out cleaning in the process moving for the suction nozzle that sucks dust.
Suction nozzle is the structure that directly sucks dust from outside, thereby can be separated with the body of dust collector with fan electromotor.For example, can say that horizontal dust collector and vertical type dust collector are the forms that body of dust collector and the suction nozzle body that is formed with suction nozzle are separated.
At this, horizontal dust collector is connected with body of dust collector by extension by suction nozzle body conventionally, thereby can be described as the dust catcher that can change the distance between suction nozzle body and body of dust collector in the time carrying out cleaning.This is because the movement of suction nozzle body and body of dust collector or mobile not synchronously formation all the time.
Different from horizontal dust collector, the suction nozzle body of vertical type dust collector and the movement of body of dust collector or movement are synchronously carried out all the time.This is that suction nozzle body directly combines with body of dust collector because in vertical type dust collector.
Stick vacuums can be closely similar with above-mentioned upright vacuum.This is because suction nozzle body directly combines with body of dust collector.Therefore, can divide stick vacuums and upright vacuum by the difference of relative size
On the other hand, in stick vacuums, have when when cleaning body of dust collector from ground upwards part every stick vacuums.In fact, this stick vacuums only can be considered as by suction nozzle body in ground moving or movement.
Above-mentioned horizontal dust collector, vertical type dust collector and stick vacuums move by user's thrust or pulling force.That is, user can promote or pull body of dust collector or suction nozzle body that above-mentioned body of dust collector or suction nozzle body are moved in order to clean, thereby carries out cleaning.
Similarly, robot cleaner also can comprise suction nozzle body and body of dust collector.But under normal circumstances, the suction nozzle body of robot cleaner can not divided with body of dust collector mutually., suction nozzle body can be a part for body of dust collector.Above-mentioned robot cleaner can have the feature of passing through the driving automated movement of motor in order to clean.
In above-mentioned multiple dust catcher, at least one in body of dust collector, suction nozzle body at ground moving to clean.Particularly, can move horizontally with respect to ground, make suction nozzle body suck dust from ground.And the same with suction nozzle body, body of dust collector also can move horizontally with respect to ground.Certainly, as mentioned above, both can carry out synchronizing moving or asynchronous movement.And both can form separately or merge formation.
Therefore, body of dust collector or suction nozzle body all can be called the moving part body to clean at ground moving.
The enforcement environment of moving part body is very many.Wall, furniture, chair, sofa, bed and the desks etc. of variform can become the barrier of the enforcement that hinders moving part body.As a rule, due to user fail identification or dust catcher itself fail identification cause moving part body and above-mentioned barrier to collide.
Due to this collision, not only can produce the impaired problem of moving part body, can also produce the impaired problem of barrier.And, can produce noise owing to frequently bumping, and cannot clean smoothly.
Below, as an example of dust catcher, common horizontal dust collector is described, and the problem producing in common dust catcher is described.
As shown in Figure 1, dust catcher 10 comprises body of dust collector 1 and suction nozzle body 2.Between above-mentioned body of dust collector 1 and suction nozzle body 2, can there is extension 3.One end of above-mentioned extension 3 is connected with the connecting portion 5 of body of dust collector 1, and the dust flowing into suction nozzle body 2 flows into the inside of body of dust collector 1 by extension 3 and above-mentioned connecting portion 5.

Above-mentioned body of dust collector 1 has wheel 9, so that body of dust collector 1 is exercised.And above-mentioned body of dust collector 1 can have the attaching plug 7 for connecting external power source.
User holds operating portion 8, promotes or pulls extension 3 that suction nozzle body 2 is exercised, and carrying out cleaning.Now, user never takes one's eyes off the front of suction nozzle body 2.Therefore, in general, if the front of suction nozzle body 2 exists barrier, user can change moving direction or stop exercising.
But exist barrier in two sides of suction nozzle body 2 or both sides forwardly, in most of the cases user has little time to change moving direction or has little time to stop and exercising.For example, in the time that suction nozzle body 2 is inserted in inside to gap, the above-mentioned gap that is greater than expectation at the width of suction nozzle this subject, often there is two sides of suction nozzle body 2 or the both sides in front and thing that barrier collides.
Therefore,, because these suction nozzle bodies 2 bump with barrier, the impaired or destroyed worry of suction nozzle body or barrier is increased.
Impaired or the damaged worry being caused by these collisions can be more serious at body of dust collector 1.This is because the volume and weight of body of dust collector 1 is more heavy more greatly than suction nozzle body.
Relatively, user easily controls the moving direction of suction nozzle body 2.But relatively and be not easy to control the direction of body of dust collector 1.This is because the enforcement of common body of dust collector 1 can be carried out in the time that user pulls extension 3 or suction nozzle 4.Therefore, utilize very large power to pull body of dust collector 1.
Now, may there is very serious collision with barrier in above-mentioned body of dust collector 1.Therefore, the possibility impaired or damage of initiation body of dust collector 1 or barrier is very large.
And, may often there is the situation that body of dust collector 1 cannot depart from because being stuck in turning.This situation is most of may be occurred in the situation that user and the residing position of suction nozzle body 2 and the residing position of body of dust collector 1 divide by turning., most ofly may occur in user because seeing in the situation of body of dust collector 1 at turning.
In this case, user can pull body of dust collector 1 by larger power, or temporarily stops cleaning the position of mobile subscriber and nozzle.Therefore, may make the impaired maximization of body of dust collector or barrier, or produce the problem that sweeping efficiency reduces.
Recently, home appliance is characterised in that, not only it is functional, and appearance design is also very attractive in appearance.Therefore, body of dust collector 1 or appearance design are day by day attractive in appearance.But because the impaired of outward appearance occurs this frequently bumping, thereby can reduce the reliability of product.

In order to solve the problem producing because of collision, suction nozzle body 100 can have buffer 90.Above-mentioned buffer 90 can be called to suction nozzle buffer device 90.
Suction nozzle buffer device 90, due to the property difference of suction nozzle body 100 and above-mentioned body of dust collector 30, makes the shape of buffer or shape or the structure difference of structure and buffer support portion.This is because there is the difference of bump between the load, barrier of suction nozzle body 100 itself form and impulsive force.
As shown in Figure 7, buffer 90 can circular in configuration., can ringwise band form.And above-mentioned buffer 90 can be supported by buffer support portion 91.Above-mentioned buffer support portion 91 can so that the mode that above-mentioned buffer 90 can rotate by sliding support.Therefore, above-mentioned buffer support portion 91 can be called to buffer rail.And above-mentioned buffer rail 91 can be fixing by guide rail fixed part 92.
At this, above-mentioned guide rail fixed part 92 can be formed at the lower body 102 in suction nozzle body 100.Therefore, buffer support portion can comprise above-mentioned buffer rail 91 and guide rail fixed part 92.Thus, Bunper assembly can comprise buffer and buffer support portion.Therefore, buffer support portion 91,92 can comprise buffer rail 91, and above-mentioned buffer rail 91 is so that the mode that above-mentioned buffer 90 slides to direction of rotation supports buffer 90.
Above-mentioned buffer rail 91 and guide rail fixed part 92 not only can be formed at lower body, can also be formed at upper body 101.Type by both closes, and buffer 90 is stably supported by buffer rail 91 in the mode that can rotate.Therefore, suction nozzle buffer device 90 and buffer support portion 91,92 can be formed at upper body 101 and lower body 102.
At this, preferably, the shape of said suction nozzle body 100 also ringwise, with corresponding with the shape of annular buffer 90.Therefore, preferably, above-mentioned buffer 90 forms the outermost of front and the both sides of suction nozzle body 100.And preferably, buffer 90 does not expose to the rear of suction nozzle body 100.This is because rotary connector 80 forms the rear outermost of suction nozzle body 100.
Too, if apply tangential direction external force to buffer 90, buffer 90 rotates the present embodiment.The moving direction that this means suction nozzle body 100 is converted.
Therefore, forwards or side and barrier collide in the situation that, can change the moving direction of suction nozzle body 100, thus shock absorbing power, and can significantly reduce the generation of noise.
And, due to the rotation of the slip by buffer 90, make the structure of buffer 90 and buffer support portion 91,92 very simple, can prevent thus the increase of the overall weight of suction nozzle body 100.
On the other hand, for the formation of this circular buffer 90, can form hollow 104 at above-mentioned body 100.

And, equally also can form hollow 104 at said suction nozzle body 100.
On the other hand, due to the arc shape of above-mentioned buffer 90, be necessary to limit the slip separation distance of above-mentioned buffer 90.In other words, be necessary to limit the anglec of rotation of buffer 90.For this reason, can form slip stop section 107 in the both-side ends of buffer 90 or at the left and right of buffer 90 end.This slip stop section 107 specifically can be formed at body 100.
For example, as shown in Figure 9, produce in the both-side ends of buffer 90 excess room that can slide by slip stop section 107.A side end at above-mentioned buffer 90 slides, and in situation about contacting with above-mentioned slip stop section 107, the slip of above-mentioned buffer 90 will stop.
Excess room 108 by this slip stop section 107 or excess length can limit the anglec of rotation of buffer 90.This slip stop section 107 is formed at the both-side ends of buffer 90, and can make buffer 90 to bidirectional rotation.Certainly, clearer and more definite for this is carried out, can also form not shown elastomeric element, so that buffer 90 returns to initial position after rotation.
On the other hand, preferably, above-mentioned excess room 108 is not exposed to the outside of body 100.Preferably, the both-side ends of above-mentioned buffer is not exposed to the outside of body 100 specifically.This is because buffer 90 can depart from, and can flow into foreign matter to above-mentioned excess room 108.
Therefore, preferably, have for covering above-mentioned excess room or covering the damper cover 10 of the both-side ends of above-mentioned buffer.Above-mentioned damper cover 105 can form in one mode with body 100.
