Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, the burner air intake device disclosed in this embodiment includes a fan housing 1, an air inlet 2 for air to enter is formed in the fan housing 1, a baffle 3 circularly disposed is rotatably connected to the fan housing 1, and a plurality of air passing holes 4 are formed in the baffle 3. By rotating the baffle 3, when the air passing hole 4 is aligned with the air inlet 2, air can pass through the air passing hole 4 and the air inlet 2; when the solid part of the baffle 3 rotates to the air inlet 2, the air inlet 2 can be blocked, air is prevented from passing through the air inlet 2, and the air inlet volume of the fan can be controlled manually by adjusting the position of the baffle 3.

Referring to fig. 1 and 2, the circle center of the baffle 3 is rotatably connected with the fan shell 1 through a pin shaft 5. The pin shaft 5 penetrates through the baffle 3 and is rotationally connected with the baffle 3, and the pin shaft 5 is inserted into one end of the fan shell 1 and is fixed with the fan shell 1 in an interference fit mode, so that the baffle 3 rotates by taking the pin shaft 5 as an axis. The lower groove 6 for the baffle 3 to be placed is formed in the fan shell 1, the lower groove 6 is in a circular shape, the height from the groove bottom of the lower groove 6 to the upper end of the lower groove 6 is equal to the thickness of the baffle 3, the baffle 3 rotates in the lower groove 6, and the lower groove 6 is provided with the effect of stabilizing the baffle 3.

Referring to fig. 2 and 3, a plurality of tooth-shaped grooves 7 located on the sides are formed in the baffle 3, a through hole 8 perpendicular to the surface of the fan housing 1 is formed in the fan housing 1, a limiting rod 9 penetrating through the through hole 8 is slidably arranged on the fan housing 1, an inner disc 10 is fixed at one end of the limiting rod 9 inserted into the fan housing 1, an outer disc 11 is fixed at one end of the limiting rod 9 penetrating out of the fan housing 1, the diameters of the inner disc 10 and the outer disc 11 are larger than the aperture of the through hole, the maximum sliding distance of the limiting rod 9 is limited by the arrangement of the inner disc 10 and the outer disc 11, and the limiting rod 9 is prevented from completely falling out of the through hole 8. The part of the limiting rod 9 penetrating out of the fan shell 1 is positioned in a tooth-shaped groove 7. The limiting rod 9 is provided with a yielding groove 12 for the baffle 3 to pass through, when the yielding groove 12 is aligned with the tooth-shaped groove 7, namely, the yielding groove 12 and the tooth-shaped groove 7 are positioned on the same plane, and the baffle 3 can rotate through the yielding groove 12. The fan shell 1 is also provided with a reset component 13 which is used for driving the limiting rod 9 to move and enabling the solid part of the limiting rod 9 to move into the tooth-shaped groove 7.

Referring to fig. 2 and 3, the reset component 13 is a spring 14, one end of the spring 14 is fixed to the inner side wall of the fan housing 1, and the other end of the spring 14 is fixed to the inner disk 10. When the limiting rod 9 is free from the artificial external force and is stable, the solid part of the limiting rod 9 is positioned in the tooth-shaped groove 7, so that the rotation of the baffle 3 is limited. When the baffle 3 needs to be rotated, force is manually applied to the outer disc 11, so that the limiting rod 9 moves into the fan shell 1 until the abdicating groove 12 is aligned with the toothed groove 7. A circular channel 15 is fixedly arranged on the inner side wall of the fan shell 1, the disc is slidably arranged in the circular channel 15, the spring 14 is positioned in the circular channel 15, and the circular channel 15 is arranged to protect the spring 14.

Referring to fig. 1 and 2, an extension block 16 is fixedly arranged at one end of the outer disc 11 facing the fan housing 1, and when the limiting rod 9 moves inwards the fan housing 1 and the extension block 16 abuts against the fan housing 1, the abdicating groove 12 is aligned with the toothed groove 7. Need not to judge deliberately whether to align in groove 12 and the flute profile groove 7 of stepping down, the staff only need press outer disc 11 hard for gag lever post 9 removes in fan casing 1, until extension piece 16 with fan casing 1 lateral wall butt can, play the effect of convenient control.

Referring to fig. 3, the solid portion of the baffle 3 located between two adjacent tooth-shaped grooves 7 is a mark portion 17, and the mark portion 17 is provided with a mark for displaying the opening degree of the baffle 3, for example, the surface of the mark portion 17 is engraved with numbers (not shown in the figure) such as 1, 2, 3, 4, 5, etc.; the staff is helped to judge the rotating position of the baffle 3 and the size of the overlapping part of the air passing hole 4 and the air inlet 2.

Referring to fig. 3, the outer disc 11 is sleeved with a rubber sleeve 18 to protect fingers of workers.

The concrete working condition effects are as follows:

when the limiting rod 9 is not subjected to an artificial external force, the solid part of the limiting rod 9 is positioned in one toothed groove 7 of the baffle 3, so that the rotation of the baffle 3 is limited. When the air inlet volume of the fan needs to be adjusted, a worker applies a force towards the direction of the fan shell 1 to the outer disc 11, so that the extension rod moves towards the inside of the fan shell 1, the spring 14 is stressed and stretched until the extension block 16 abuts against the fan shell 1, the tooth-shaped groove 7 is aligned with the abdicating groove 12, and the baffle 3 can be rotated. After the baffle 3 is adjusted to a proper position, the new tooth-shaped groove 7 is aligned with the abdicating groove 12, then the outer disc 11 is loosened, the inner disc 10 moves towards the direction close to the inner side wall of the fan shell 1 under the force of the spring 14, the solid part of the limiting rod 9 moves into the new tooth-shaped groove 7, the effect of limiting the rotation of the baffle 3 is achieved, and the baffle 3 can be adjusted without the help of a virtual tool.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
