The specific embodiment
To describe preferred embodiment of the present invention in detail below, example of the present invention be shown in the accompanying drawing.
Shown in Fig. 3 and 4, upright vacuum cleaner according to the present invention comprises: the main body 1 that wherein has spatial accommodation; Be installed in the handle 6 of main body 1 upside; Be installed in main body 1 and produce the fan electromotor 2 of suction; Be arranged in fan electromotor 2 suction sides and filter the filter 3 of dust; Be used to hold the dirt chamber 4 that filter 3 reaches the dust that is filtered by filter 3; And, be used for sucking external dust by the operation of fan electromotor 2 by connecting the suction nozzle 100 that flexible pipe 7 is connected with dirt chamber 4.
Suction nozzle 100 comprises: be provided with the shell 110 of suction inlet 20, suction inlet has the structure of opening wide towards the floor; Be rotatably installed in the cylindrical brush 30 of suction inlet 20, and on the longitudinal direction of this brush, be furnished with a plurality of bristles 31; Be used in predetermined angular range, reaching backward the reciprocally brush-driven device 40 of rotary brush 30 forward; First intake line 50 with inlet 51 of when direction is forward rotated, arranging when brush 30 corresponding to the dust direction of motion; Second intake line 60 with inlet 61 of when brush 30 rotates on direction backward, arranging corresponding to the dust direction of motion; And be used for first intake line 50 is connected to the tube connector 115 that is connected flexible pipe 7 with second intake line 60.
Bristle 31 is installed on the brush 30 equably being many rows on the longitudinal direction of brush 30.
As shown in Figure 5, brush-driven device 40 comprises: the drive motors 41 that is used to provide driving force; And the driving force delivery unit 42 that is used for the driving force of drive motors 41 is sent to brush 30, so brush 30 can reciprocally rotation in predetermined angular range.
Driving force delivery unit 42 comprises: be fixed in the motor shaft 43 of drive motors 41 and with the swingle 44 of motor shaft 43 coaxial rotations; Be installed in the hinge mount 45 of brush 30 external peripheral surfaces one side; And connecting rod 46, wherein an end of connecting rod 46 is connected with swingle 44 hinges in the position that is eccentric in swingle 44 pivots, and the other end of connecting rod 46 is connected with hinge mount 45 hinges, therefore carries out the angle by the rotation of swingle 44 and moves back and forth.
Driving force delivery unit 42 converts rotatablely moving of drive motors 41 motor shafts 43 to the back and forth rotation and back and forth rotation backward forward of brush 30.
Shown in Fig. 6 and 7, the inlet 51 of first intake line 50 is arranged in the rear side of brush 30 and extends to the rear side of shell 110, and the outlet 52 of first intake line 50 links to each other with tube connector 11 5.
When brush 30 rotated forward, promptly brush 30 was rotated counterclockwise as shown in Figure 7, and therefore first intake line 50 moves to dust the rear side of suction inlet 20 as the flow channel of the dust of bristle 31 sweepings of passing through brush 30.
Simultaneously, preferably in order more effectively to suck air, the inlet 51 of first intake line 50 forms agley towards the direction of suction inlet 20.
The inlet 61 of second intake line 60 be arranged to the form of opening wide towards the floor in the front side of brush 30 and on the suction inlet 20 circumference extend, and the outlet 62 of second intake line 60 links to each other with first intake line 50.
When brush 30 rotated backward, promptly brush 30 turned clockwise as shown in Figure 7, and therefore second intake line 60 moves to dust the front side of suction inlet 20 as the flow channel of the dust that passes through bristle 31 sweepings.
Preferably, in order to increase the aisle spare that sucks dust, the width with suction inlet 20 left and right directions is identical basically for the width of second intake line, 60 inlets, 61 left and right directions.
In order to increase the suction of channel interior, the width of second intake line, 60 left and right directions is reduced towards outlet 62 gradually by inlet 61.Therefore, the width of suction passage 60 fore-and-aft directions reduces (referring to Fig. 4) gradually towards the both sides of second intake line 60.
Preferably, guidance part 70 is formed on the outlet 62 of second intake line 60, is used for crossing towards first intake line, 50 directed stream the air of second intake line 60.Guidance part 70 keeps being flowed to by second intake line 60 constant voltage and the constant flow of the air of first intake line 50.
Guidance part 70 can be outstanding from the inwall of second intake line 60, and the thickness of guidance part 70 diminishes towards first intake line 50.Preferably guidance part 70 forms agley towards two surfaces 72 and 74 of first and second intake lines 50 and 60.
Hereinafter, with the operation of explanation according to vacuum cleaner suction head of the present invention.The direction of motion of each parts illustrates with reference to the accompanying drawings, and the present invention is not limited to these direction of motion.
When electric power is sent into vacuum cleaner, because the suction that fan electromotor 2 produces produces suction at suction inlet 20 places of suction nozzle 100.By this suction, the dust on the floor sucks by suction inlet 20, therefore sends into the dirt chamber 4 of main body 1.
Shown in Fig. 8 and 9, produce revolving force at drive motors 41 places.When the revolving force of drive motors 41 was sent to brush 30 by driving force delivery unit 42, brush 30 is reciprocally rotation in predetermined angular range.
As shown in Figure 8, when brush 30 rotated forward, promptly brush 30 was rotated counterclockwise, the dust of bristle 31 on the direction sweeping floor of suction inlet 20 rear sides.In view of the above, the great majority in the dust of sweeping are sent into the inlet 51 of first intake line 50 that is arranged in suction inlet 20 rear sides.
As shown in Figure 9, when brush 30 rotated backward, promptly brush 30 turned clockwise, the dust of bristle 31 on the direction sweeping floor of suction inlet 20 front sides.In view of the above, the great majority in the dust of sweeping are sent into and are arranged in the inlet 61 of suction inlet 20 at second intake line 60 of front side.Then, dust flows along second intake line 60, and sends into first intake line 50 by the outlet 62 of second intake line 60.
The dust of sending into first intake line 50 and second intake line 60 enters tube connector 115, enters the dirt chamber 4 of main body 1 by connecting flexible pipe 7 then.The dust that filters by filter 3 in 4 inside, dirt chamber is stayed in the dirt chamber 4, and the clean air that filters by filter 3 drains into main body 1 outside.
Vacuum cleaner suction head 100 according to the present invention is configured to brush 30 can reciprocally rotation in predetermined angular range.In view of the above, the shared entire area sweeping equably of suction nozzle 100.
Equally, be used to suck first intake line 50 of dust and the both sides that second intake line 60 is separately positioned on the direction on brush 30 sweeping floors.In view of the above, the dust of sweeping successfully can be sucked main body 1.
In addition, the width with suction inlet 20 left and right directions is identical basically to be arranged in the width of second intake line, 60 left and right directions of suction inlet 20 front sides, and the width of second intake line, 60 left and right directions is little by little reduced towards outlet 62 by inlet 61.In view of the above, by using suitable suction, can successfully clean the whole zone of second intake line, 60 processes.
Because the present invention can implement under the situation that does not break away from spirit of the present invention or essential feature in many ways, it will also be appreciated that the above-mentioned specific embodiment is not limited by any details of aforementioned specification, unless it is dated especially, can very wide in range explanation in the defined spirit and scope of claims, therefore belong to the border of claim and the institute in the scope and change and revise, therefore the equivalent structure of perhaps this border and scope also is contained in the appended claim.
