Abstract
The invention relates to a straight-pipe suction control structure of a cleaner, which comprises an annular shallow slot which is arranged at the outer side surface of the straight pipe, two air inlets which are relatively arranged inside the shallow slot and pass through the pipe wall, and a rotary vane with a kerf is sleeved at the slot. The width of the rotary vane is the same as that of the slot and two parts prominent inwards are arranged at the inner side face of the rotary vane while the outer side face thereof is provided with transversely-arrayed ridges; the two parts in the inner side face of the rotary vane are respectively inserted into the two air inlets inside the slot of the pipe wall, wherein, one part is arranged at one end of the vane while the other one is arranged at the middle part thereof. The rotary vane can rotate around the outer side face of the straight pipe and one air inlet of the pipe can open and close during rotation. When the air inlet is open, air outside the pipe can enter the pipe and the suction of a sucker of the cleaner decreases; when the air inlet is closed, air outside the pipe can not enter the pipe and the suction of the sucker thereof increases. The invention can adjust the size and air inlet volume of the air inlet by rotating the rotary vane so as to control the suction of the cleaner.
Description
Technical field
The present invention relates to dust catcher, particularly relate to the air intake duct of vacuum cleaner.
Background technology
Dust catcher is a kind of household electrical appliance of indoor cleaning health, is used for removing the dust in ground, carpet, wall, furniture and various slits.Dust catcher mainly comprises body, suction nozzle and air intake duct, and air intake duct is connected between suction nozzle and the body.With motor and blower fan is that the aspirator that dominant shape becomes is arranged in the body, and the air inlet of body inner blower is connected with the air entry of suction nozzle under shed by air intake duct.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 is drawn in the intrinsic dust bucket 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.
Dust catcher is broadly divided into vertical with horizontal from profile.Dress disposal box in the horizontal dust collector housing approximate circle cone, thin slightly first half, thick slightly latter half of built-in motor and blower fan, suction nozzle separate with housing and are connected by long air intake duct.Vertical type dust collector housing approximate circle tubular, built-in motor and blower fan, suction nozzle are arranged on housing bottom and are connected by short air intake duct.
No matter be vertical type dust collector or horizontal dust collector, air intake duct generally all is made of inflexible straight tube and flexible flexible pipe.In the horizontal dust collector, inflexible straight tube is used to move the suction nozzle that is connected, and straight tube can also stretch simultaneously, so that adjust the position of dust suction better; In the vertical type dust collector, air intake duct places the outside of body casing, and inflexible straight tube is used for flexible pipe and puts and move in the upright body casing outside.
Fig. 1 is a kind of horizontal dust collector schematic diagram of prior art.
As shown in Figure 1, dust catcher mainly is made up of body 7, suction nozzle 1 and air intake duct, and air intake duct is connected between suction nozzle 1 and the body 7.Air intake duct straight tube 2 and flexible pipe 5 constitute.Being provided with motor and blower fan in the body 7 is the aspirator that dominant shape becomes, and the air inlet of body 7 inner blowers is communicated with the air entry of suction nozzle 1 under shed by air intake duct.Dust bucket 6 in the body 7 gathers the dust by suction nozzle 1 and air intake duct suction, and discharges from the exhaust outlet 9 at body casing 8 rear portions after filtering.The both sides of casing 8 are provided with roller 10, are convenient to mobile body of dust collector 7.
Fig. 2 is the straight tube schematic diagram of the vertical type dust collector of prior art.
From Fig. 1 and Fig. 2 as can be seen, the dust catcher air intake duct of prior art all has the straight tube structure of tube wall sealing, is sent in the body with the air of fixing suction with the band dust of suction nozzle suction.But the dust catcher air intake duct of prior art can not be done any adjusting and control to dust catcher.Although the suction rate of dust catcher is divided into the class that can operate control, still, generally has only high, medium and low three retainings, can not be with continuously, fine suction changes the dust suction of the different cleaning objects such as adapting to ground, bed surface, sofa, corner and the scope of operation.Especially, the straight tube of air intake duct is positioned at the position of dust catcher handled easily and control, but can not do any adjusting and control to dust catcher suction, and this is the problem of the dust catcher straight tube structure existence of prior art, influences the more convenient use of dust catcher.
Summary of the invention
The problem that can not do any adjusting and control to dust catcher suction that exists at the straight tube of the dust catcher air intake duct of above-mentioned prior art, the present invention releases and air admission hole is set on tube wall and is combined with the straight tube structure of rotating blade around pipe, rotate size and the intake that blade blocks air admission hole by regulating, realize control dust catcher suction.
The suction control structure of suction cleaner straight pipe that the present invention relates to comprises: the air admission hole that sees through tube wall is set in the ring-type shallow slot of straight tube lateral surface setting, the shallow slot and is enclosed within nicked blade on the shallow slot.The width of blade is identical with the width of shallow slot, and blade can rotate in shallow slot.
Straight tube lateral surface ring-type shallow slot is oppositely arranged 2 air admission holes that see through tube wall, and air admission hole can be blocked by blade.The blade medial surface has two inwardly outstanding fasteners, and the lateral surface of blade has transversely arranged rib.A fastener of blade medial surface places an end of blade, and another fastener places the middle part of blade, and two fasteners insert respectively in 2 interior air admission holes of tube wall shallow slot, play position-limiting action.When blade rotates, insert move left and right in the air admission hole that fastener in the tube wall shallow slot air admission hole is limited in the shallow slot tube wall in shallow slot.
Blade is in the process of straight tube lateral surface rotation, and an air admission hole of straight tube is blocked by blade, and another air admission hole can open and close from the blade incision.When air admission hole was unlimited from the blade incision, the outer wind of straight tube was drawn into, and the suction head of suction cleaner suction of straight tube one end just reduces.When air admission hole was closed, the outer wind of straight tube can not enter, and suction head of suction cleaner suction increases.The present invention regulates the size and the intake of air admission hole by rotating blade, realizes the control to dust catcher suction.
