Description
Technical field
The present invention relates to a kind of vacuum cleaner hair brush structure
Background technology
As shown in Figure 1 and Figure 2, common dust catcher is made up of main body 10 and inhalation apparatus 20 substantially.Main body has pressure fan 2 and dust bag 4.Pressure fan 2 produces suction, and dust bag 4 is collected foreign matters such as dust.Inhalation apparatus 20 links together with aforementioned body 10, and air and foreign matter are sucked together.In dust catcher when work, allow main body 10 produce suction, sucks air and foreign matters by above-mentioned inhalation apparatus 20, and when foreign matter is collected in dust bag 4, discharges after air is filtered.
Above-mentioned inhalation apparatus 20 comprises cleaner head 22, hairbrush 26, suction nozzle 28, intake line 29.Cleaner head 22 is formed with the suction inlet 22a that can suck air and foreign matter, and is combined in main body 10 bottoms, forms the part outward appearance of dust catcher.Hairbrush 26 can be rotatably set in the suction inlet 22a of cleaner head 22, under the effect of motor (not shown), the foreign matter on ground has been brushed lightly, and makes it floating.Suction nozzle 28 forms round said brush 26, and the foreign matter to the suction inlet 22a of above-mentioned cleaner head 22 sucks sucks.Intake line 29 is arranged between suction nozzle 28 and the dust bag 4, and the suction of pressure fan 2 is passed suction inlet 22a to above-mentioned cleaner head 22, and the foreign matter water conservancy diversion of above-mentioned suction nozzle 28 suctions to dust bag 4.
Above-mentioned inhalation apparatus 20 after the ground foreign matter suction of cleaner head 22 suction inlet 22a sides, by intake line 29, is sent to dust bag 4 to above-mentioned foreign matter by pressure fan 2 suction.Meanwhile,, make said brush 26 rotations, ground foreign matter has been brushed lightly, make it floating for the suction inlet 22a by cleaner head 22 sucks the foreign matter that deposits on the ground better.
But there are the following problems for existing dust catcher inhalation apparatus.Under the situation that the ground of not laying carpet etc. is cleaned, when each mobile dust catcher, even allow hairbrush 26 stop to drive, the hairbrush hair 26a of this hairbrush 26 can scratch ground, causes the damaged claim from the user.
Summary of the invention
In order to overcome the above-mentioned shortcoming that existing dust catcher exists, the invention provides a kind of vacuum cleaner hair brush structure, it can prevent to make ground to cause the phenomenon of scratch.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of vacuum cleaner cleaner head comprises cleaner head body, swingle, hairbrush, transmission device, drive unit, and the cleaner head body is formed with suction nozzle, and suction nozzle is used to suck air; Swingle is rotatably installed on the described cleaner head body; Hairbrush is in the state of isolating by certain angle from the central shaft of described swingle, and forms along the length direction of swingle; Transmission device is used to rotate described swingle; Drive unit is used to drive described transmission device; Described hairbrush only is formed on a privileged site of described swingle, by rotating swingle, make hairbrush and ground mutually across a certain distance, hairbrush is pressed radial formation from the swingle central shaft, this hairbrush is formed by two row, the 1st row and the 2nd row of hairbrush form acute angle, central shaft with swingle is as the criterion, the length of hairbrush is greater than the minimum range of swingle surface to ground, two row hairbrush are as the criterion when symmetrical with vertical line perpendicular to the ground, hairbrush and ground are mutually across a certain distance, transmission device carries out the arm of force of angle rotation and the revolving force of arm of force biography is constituted to the connector of swingle by being combined in drive unit, connector makes the arm of force be connected with swingle, is that swingle is rotated at the center with the torque arm.
Aforesaid vacuum cleaner cleaner head, wherein the length of hairbrush is less than the hypotenuse length that with the minimum range is the right angle equilateral triangle of height.
Aforesaid vacuum cleaner cleaner head, wherein drive unit is a motor, presses the certain angle rotation transmission device.
The cleaner head of vacuum cleaner of the present invention makes to be printed with selectedly to contact with ground, thereby can prevent hairbrush scratch ground by forming hairbrush by suitable angle and length.

The specific embodiment
As shown in Figure 3, Figure 4, vacuum cleaner cleaner head of the present invention comprises cleaner head body, swingle 60, transmission device 70, drive unit 80.The cleaner head body is formed with the suction nozzle (not shown), and suction nozzle is used to suck air, and swingle 60 is rotatably installed on the cleaner head body.Transmission device 70 is used to rotate above-mentioned swingle 60; Drive unit 80 is used to drive above-mentioned transmission device 70.
The center of above-mentioned swingle 60 is formed by torque arm 65, carries out back and forth movement by some cycles in certain angle (β).The surface 61 of above-mentioned swingle 60 is formed with hairbrush 92,94 by length direction.
Said brush 92,94 is made up of two row.Be as the criterion with torque arm 65, the row of this hairbrush 92,94 are positioned at certain angle α scope.This hairbrush 92,94 is as the criterion with central shaft torque arm 65, by forming to extraradial direction.The angle [alpha] that the 1st row 92 of said brush 92,94 and the 2nd row 94 form is an acute angle.
Here, is S1 from the surface 61 of swingle 60 to the minimum range the above-mentioned ground 100, and this minimum range S1 and swingle 60 radius sums are S2, is that the hypotenuse length of the formed right angled triangle of right-angle side is S3 with above-mentioned S2, the length L of this hairbrush 92,94 is longer than S1, and is shorter than S3.That is, 100 vertical line is as the criterion to ground with the axle center, the 1st, 2 row 92,94 of said brush 92,94, and in the time of symmetrically, the end of this hairbrush 92,94 and ground 100 maintenance certain intervals.
The central shaft torque arm 65 of above-mentioned swingle 60, one side 62a is fixed on the cleaner head body, and opposite side 62b is rotatably installed on the cleaner head body.
Above-mentioned drive unit 80 is a motor, and this motor 80 can make axle 81 by carrying out back and forth movement in the certain angle β.
Above-mentioned transmission device 70 is connected with above-mentioned axle 81, comprises the arm of force 72 and connector 74.The arm of force 72 carries out back and forth movement in certain angle β scope.Connector 74 connects arm of force 72 chord bull stick 60, is the center with above-mentioned torque arm 65, rotates swingle 60.
Below, with reference to Fig. 3, Fig. 5 a, Fig. 5 b, Fig. 5 c, the course of work of the embodiment of the invention is described.
At first, start vacuum cleaner.At this moment, the control part (not shown) of vacuum cleaner is connected power supply to above-mentioned motor 80, makes above-mentioned axle 81 carry out the angle rotation.At this moment, the arm of force 72 that is fixed on axle 81 carries out back and forth movement by certain angle β under this effect of 81.Under the back and forth movement effect of the arm of force 72, above-mentioned swingle 60 is the center with torque arm 65, is rotated by certain angle.At this moment, be formed on the hairbrush 92,94 on swingle 60 surfaces,, make the foreign matter on ground 100 floating with ground 100 frictions.
In addition, when the ground of not laying carpet is cleaned, do not need to make foreign matter floating.Therefore, as shown in Figure 7, cause scar in order to prevent said brush 92,94 to ground, adjust the anglec of rotation of 80 81 in motor, the center line of hairbrush 92,94 angle [alpha] and the vertical line 101 on ground 100 lump together.At this moment, hairbrush 92,94 can keep a determining deviation with ground 100.
In addition, as shown in Figure 6,80 81 rotations of above-mentioned motor make hairbrush 92,94 exceed the angular range that rubs with ground 100, and hairbrush 92,94 meetings and ground 100 keep a determining deviation.
The invention effect
The cleaner head of vacuum cleaner of the present invention makes hair by forming hairbrush by suitable angle and length Be brushed with selectedly and contact with ground, thereby can prevent hairbrush scratch ground.
