Abstract

A dust-collecting head is composed of upper casing, joint unit, brush extension controller and lower cover plate. The dust suction head with the structure is suitable for various ground conditions, and is convenient to operate, save time and store.

Description

Cleaner head

The utility model belongs to a kind of dust catcher, relates to the suction tip of dust catcher.

At present, home-use general dust catcher, the employed cleaner head of its dust suction is element or the assembly for fixed structure, during use, looks the situation or the structure on dust suction ground, selects to be assembled in to hold tube end.The advantage of this structure is: during use, need often change, assemble cleaner head, bother time-consumingly, simultaneously, the cleaner head number is many, and collection takes up space, and seeks during use also to be not easy.

The purpose of this utility model provides a kind of cleaner head, and a cleaner head is fit to multiple state of ground to be used, not only easy to operate saving time, and be convenient to collection.

The purpose of this utility model realizes by following scheme: cleaner head is by upper encloser, piecing devices, brush unit, the bristle telescopic control device, compositions such as lower cover, described upper encloser is a hollow, rectangular cover, upper wall has that piecing devices stretch out medium pore and switch knob stretches out the hole, be equiped with piecing devices in the lower opening, brush unit, the bristle telescopic control device, wherein piecing devices comprise end suction pipe and tube connector, the lower ending pivot of end suction pipe is coupled in the upper encloser medium pore, the upper end is stretched out by tube connector and is held pipe from medium pore and joins, brush unit is the rectangular frame less than size in the upper encloser, lower periphery in framework is planted bristle, framework is sleeved on the upper encloser inner edge guide rod with slide opening, the framework upper limb has skewed slot, one compression spring is arranged between framework lower edge and lower cover, compressing tablet and switch knob constitute the bristle telescopic control device in upper encloser by pivotly joining, both are relative with the skewed slot of rectangular frame, and lower cover is covered on upper encloser below inner edge.

Cleaner head changes a cleaner head into by a plurality of fixation kits, and is not only easy to operate, saves time, and be provided with brush unit in cleaner head, borrows stretching out or withdraw of switch knob control bristle, makes a cleaner head be suitable for the situation on multiple ground, is convenient to simultaneously collect.

Fig. 3 is the utility model embodiment exploded view.

Fig. 4 is the utility model piecing devices position cutaway view.

Fig. 5 is the utility model switch knob position cutaway view.

Be described further below in conjunction with drawings and Examples:

In Fig. 1, upper encloser 1 is the hollow, rectangular cover of a below opening, upper wall central authorities are provided with the medium pore 7 that piecing devices stretch out, pull to turn round and stretch out hole 8, hollow in the lower opening is provided with the bottom of piecing devices 2, brush unit 3, and bristle telescopic control device 4, be covered on the lower opening location with lower cover 5.

In Fig. 2, the piecing devices of establishing in the upper encloser 12 are by end suction pipe 9, tube connector 10, snap ring 11, reach axle sleeve 12 and form, wherein, end suction pipe 9 is one section bend pipe, it pivotly joins the end both sides and respectively is provided with axis hole 13, each penetrates with axle sleeve 12, passes with polygonal bar 14 again, and the pivot end of end suction pipe 9 medium pore 7 by upper encloser 1 is stretched out, stay and pivotly join end in the upper encloser and pivotly join in the medium pore 7 of upper encloser, stretch out outer pivot end of upper encloser and tube connector grafting with end cap 20.Pivot end is established hole clipping 16, trip 17 for snap ring 11 inner edges, draw-in groove 15 is arranged on the tube connector 10, snap in the draw-in groove 15 of tube connector 10 through hole clipping 16, make tube connector 10 be articulated in end suction pipe 9 pivot ends, hold pipe operation dust suction in order to connect the dust catcher hard, make it upper encloser and can vow 18 directions along holding axially back and forth rotating of pipe, also can vow that 19 directions back and forth rotate along the vertical direction of holding pipe according to arrow according to arrow.As shown in Figure 4.

In Fig. 3, the brush unit of establishing in the upper encloser 13, be one less than in the upper encloser size rectangular frame 21, the framework lower periphery is planted bristle 22, is provided with a pair of slide opening 23 in the framework 21, in order to wear close sliding sleeve 24 after, be sleeved on the guide rod 25 of upper encloser 1 inner edge.5 of framework 21 upper limbs and lower covers have a compression spring 26, because the tension force of spring makes rectangular frame 21 be pressed in upper encloser 1 inner edge location, and the bristle 22 of framework lower periphery is contracted in the upper encloser 1.Rectangular frame 21 upper limbs are provided with the skewed slot 27 of a pair of symmetry, and skewed slot 27 is relative with the switch knob and the compressing tablet of bristle control device, borrow switch knob 6 and compressing tablet 28, compacting rectangular frame 21 downward displacement location.Make bristle 22 stretch out upper encloser 1 lower end, in order to scrub ground.

Bristle telescopic control device 4 is made of switch knob 6 that stretches out upper encloser 1 and compressing tablet 28 upper encloser 1 in, and switch knob 6 and compressing tablet 28 are sleeved on the two ends of polygonal bar 14 respectively, and each under the skewed slot 27 of rectangular frame 21.Switching switch knob 6 promptly drives compressing tablet 28, and each is exerted pressure to skewed slot 27, makes rectangular frame 21 toward bottom offsets, and the compression spring 26 and the bristle 22 that compress simultaneously it under stretch out; Drive compressing tablet 28 in switching switch knob 6, break away from skewed slot 27, compression spring 26 is upheld and is pushed back rectangular frame 21, makes bristle 22 withdrawals, with the effect that reaches the loose dirt ash of brush, washes ground and pull of vacuum dust suction or water.As shown in Figure 5.

Lower cover 5 is provided with the through hole 30 of end suction pipe, and the locating flange 31 of a pair of compression spring upper end, is fixed at the inner edge of upper encloser 1 with screw 29, covers the interior relative scope of bristle of rectangular frame in upper encloser 1 lower opening.
