Description
Technical field
The present invention relates to a kind of dust catcher, particularly relate to the dust collector upper cover fixed point remaining device that can rest on any position when a kind of dust collector upper cover is opened.
Background technology
Usually, vacuum cleaner is to utilize vacuum to produce suction to suck air, makes air flow through various filters, airborne foreign matter is filtered the device in the cleaning chamber.
In general, vacuum cleaner mainly comprises aspirator and suction line, with motor and blower fan is that the aspirator that dominant shape becomes is arranged in the body, suction line comprises suction nozzle and air intake duct, and the air entry of the oriented under shed of suction nozzle and telescoping tube and flexible pipe by air intake duct communicate with the air inlet of body inner blower.During the dust catcher running, the impeller of motor drives blower fan rotates at a high speed, and the air in the dust catcher is discharged, and forms instantaneous vacuum in dust catcher, and forms a quite high Negative Pressure Difference between the ambient atmosphere.Under the effect of this Negative Pressure Difference, near the dust the suction nozzle sucks in the dust bucket in the body by air entry together with air.The air that contains dust after filtering, flows back to the dust catcher outside from air outlet again in the body dust bucket.Like this, just reach the effect of dust out, clean floor.The suction rate of vacuum cleaner is divided into a plurality of class of operating control, adapts to the scope of operation of different cleaning objects such as ground, bed surface, sofa, corner, so that aspirate dust everywhere better.
Press the use and the moving method of vacuum cleaner, can be divided into horizontally, vertical, portable etc., little foreign matters such as dust clean: ground such as vertical easy cleaning woollen blanket with comparalive ease in the wherein horizontal family that is mainly used in; The portable narrow positions such as step, desktop of easily cleaning.
In addition, vacuum cleaner can be divided into filer element type, cyclone type to the mode that foreign matters such as dust, hair filter by it.Wherein filer element type makes the air that contains foreign matter flow through a kind of dry goods dust bag, foreign matter filtered to change dust bag periodically, and cyclone type makes the suction air generation swirling flow that contains foreign matter, fall the bottom surface with sucking the deadweight effect tenesmus of airborne foreign matter in rotary course, do not need dust bag, its use amount just constantly rises.
Dust catcher is for adapting to the cleaning in different cleaning face or corner, and common brush head of dust collector can have difformity and purposes, as tapered suction nozzle, and selective uses such as the brush head of dust collector of rectangle.
It is integrally formed that common dust catcher conical shell connects adapter, the conical shell Duanxi inkstone is provided with suction nozzle, its inside is formed with air intake duct, make its inside be formed with bigger dust suction space, and in a side and the logical sweep-up pipe adapter of air intake trough rim, during use, dust sucting motor work behind the importing electric current, dust on the cleaning face enters in the suction head of suction cleaner through the suction nozzle of conical shell end face, and through air intake duct, sweep-up pipe adapter, hose, the device of passing by on one's way enter the dust collecting part of gathering suction.
Existing dust catcher comprises main body of dust collector and loam cake, and main body and loam cake are by the connecting rod combination, and loam cake rests on the maximum position of opening when opening loam cake.But the dust collector upper cover of this structure can not rest on the optional position of opening, and can bring some inconvenience to the user.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, provide a kind of when opening dust collector upper cover loam cake can rest on any position of opening and dust collector upper cover fixed point remaining device that can slippage.
The technical solution adopted in the present invention is: dust collector upper cover fixed point remaining device comprises body of dust collector, loam cake and connecting rod; One end of described connecting rod is connected with loam cake, and the other end is connected with body of dust collector; The outer end of the other end of described connecting rod is provided with a gear, and the cavity arranged outside that can hold connecting rod in the described body of dust collector has slideway, is respectively arranged with dentalation on the sidewall of described slideway; Described gear slides in slideway.
Described gear is cylindric; Described dentalation is a tooth bar.
Between the body wall of described dentalation and body, be provided with spring.
Described slideway is an arc, and the movement locus of its radian and gear is suitable.
The invention has the beneficial effects as follows: because connecting rod is provided with cylindrical gear, and on the slideway that is provided with on the running orbit of gear, be formed with tooth bar, the wheel and rack location of matching, guarantee that any position of dust collector upper cover in opening procedure all can stop, this convenience simple in structure, suitable applying.

The specific embodiment
Below, with the specific embodiment the present invention is described in further detail in conjunction with the accompanying drawings:
To shown in Figure 7, dust collector upper cover fixed point remaining device of the present invention comprises body of dust collector 10, loam cake 20 and connecting rod 30 as Fig. 1; One end of described connecting rod 30 is connected with loam cake, and the other end is connected with body of dust collector 10; The outer end of the other end of described connecting rod 30 is provided with a gear 31, and described gear 31 is cylindric; The cavity arranged outside that can hold connecting rod 30 in the described body of dust collector 10 has slideway 11, and described slideway 11 is an arc, and the angle that its radian and loam cake 20 are opened is suitable; Be respectively arranged with dentalation 12,13 on the sidewall of described slideway 11, described dentalation 12 can be a tooth bar; Described gear 31 slides in slideway 11; Between the body wall of described dentalation 13 and body 10, be provided with spring 40, untie the constraint of tooth bar to gear, described dentalation 13 can move, dentalation 13 pushes to spring 40 sides under the effect of power when closing loam cake, gear 31 and dentalation 13 are broken away from, close loam cake smoothly.
Roller gear projection in the dust catcher is slided along the track that slides when loam cake is opened, because the auto-lock function of gear and both sides tooth bar, loam cake can stop at different fixed positions; When needs close dust collector upper cover, with handle a little firmly, press spring to the tooth bar direction, gear is convenient to tooth bar and is separated like this, is free to this moment move, and loam cake closes.
