The invention is further configured to: the driving mechanism comprises a driving rod, an elastic piece and a driving plate, the driving rod is rotatably connected to the throttle body and connected with the rotary inner barrel, two ends of the elastic piece are respectively connected with the driving rod and the throttle body, and the driving plate is fixed at one end, far away from the throttle body, of the driving rod.

Through adopting above-mentioned technical scheme, it is rotatory to drive the actuating lever through the drive plate, can make the actuating lever drive rotatory inner tube and rotate, reaches the effect of admitting air and shearing carbon deposit, when stopping exerting the effort to the drive plate, can realize restoring to the throne through the elastic force effect of elastic component, makes throttle valve closed tightly.

In conclusion, the invention has the following beneficial effects:

drive rotatory inner tube through actuating mechanism and rotate, make interior shear groove toward the direction removal that is close to outer shear groove, when interior shear groove corresponds with outer shear groove, can make the air through the intake duct, interior shear groove derives from outer shear groove again, when having the carbon deposit on the inner wall of interior shear groove, can cut off the carbon deposit through forming the shearing effect between outer shear groove and the interior shear groove, make rotatory inner tube can rotate and will rotate the inner tube through actuating mechanism and reset, with interior shear groove shutoff, thereby be difficult for causing the problem that the throttle closure is not tight, the throttle jamming.

Detailed Description

The invention is further described with reference to the accompanying drawings.

As shown in fig. 1 to 4, a throttle valve for drum type intake includes a throttle body 1. An air inlet 11 is arranged on the side wall of the throttle body 1, and a rotary inner cylinder 2 and a fixed outer cylinder 4 are arranged on the inner wall of the air inlet 11. One ends of the rotary inner cylinder 2 and the fixed outer cylinder 4 are opened.

The fixed outer cylinder 4 is positioned outside the rotating inner cylinder 2, and the inner wall of the fixed outer cylinder 4 is attached to the outer wall of the rotating inner cylinder 2. The opening of the rotary inner cylinder 2 corresponds to the air inlet 11, and the fixed outer cylinder 4 is arranged coaxially with the rotary inner cylinder 2.

An inner shearing groove 3 is arranged on the outer wall of the rotary inner cylinder 2, and an outer shearing groove 5 is arranged on the fixed outer cylinder 4. The inner shearing groove 3 corresponds to the outer shearing groove 5.

The two ends of the inner transverse surface 33 are respectively connected with the inner chamfered surface 31 and the inner straight surface 32.

The cross section of the external shearing groove 5 is in an equilateral trapezoid shape and comprises a first external straight surface 51, a first external inclined surface 52, a second external straight surface 53 and a second external inclined surface 54 which are connected in sequence. Wherein the first outer straight surface 51 corresponds to the inner chamfer surface 31.

A driving mechanism 6 for driving the rotary inner cylinder 2 to rotate is arranged on the outer wall of the throttle body 1. The drive mechanism 6 includes a drive rod 61, an elastic member 62, and a drive plate 63. The driving rod 61 is rotatably connected to the throttle body 1 and connected to the rotary inner cylinder 2. The two ends of the elastic element 62 are respectively connected with the driving rod 61 and the throttle body 1. The drive plate 63 is fixed to an end of the drive lever 61 remote from the throttle body 1. The drive rod 61 is arranged coaxially with the rotary inner cylinder 2.
