Example 1
Referring to fig. 1 to 4, the damper adjusting device provided by the utility model is used for a kitchen range provided with an upper air inlet combustor. The damper adjusting device comprises an ejector pipe 101, a shrinkage pipe 102 and a fastener 103.
The air inlet 104 of the injection pipe 101 is opposite to the gas nozzle 105 of the kitchen range, so that the gas sprayed out of the gas nozzle 105 can enter the injection pipe 101, and the injection pipe can introduce the gas into the combustion disc. The shrinkage tube 102 is arranged in the air inlet 104 of the injection tube 101, the size of the tube cavity of the shrinkage tube 102 gradually expands along the direction away from the air inlet 104 of the injection tube 101, and the large-size end of the tube cavity of the shrinkage tube 102 is opposite to the gas nozzle 105 of the kitchen range.
That is, the inner wall of the shrinkage tube 102 is in a horn shape, and the small opening end of the shrinkage tube 102 is provided with an installation end which is connected with the injection tube 101; the large opening end of the shrinkage tube 102 is an inlet end, and the inlet end is opposite to the gas nozzle 105, so that gas sprayed out of the gas nozzle 105 can enter the injection tube 101 from the shrinkage tube 102, and the circumferential air can enter the injection tube 101 from the large opening end of the shrinkage tube 102 to be mixed with the gas due to the large opening size of the inlet end of the shrinkage tube 102.
The shrink tubing 102 is capable of reciprocating relative to the ejector tubing 101 to either approach or depart from the gas nozzle 105. When the shrinkage tube 102 is close to the gas nozzle 105, when the distance between the shrinkage tube 102 and the gas nozzle 105 is smaller, the shielding effect of the gas nozzle 105 on the inlet end of the shrinkage tube 102 is larger, the primary air inlet area is smaller, the resistance of the gas nozzle 105 on the air inlet is larger, the air inlet quantity is smaller, and the problem that the air source is easy to leave flame can be solved; when the shrinkage tube 102 is far away from the gas nozzle 105, when the distance between the shrinkage tube 102 and the gas nozzle 105 is large, the primary air inlet area is large, the resistance of the gas nozzle 105 to the air inlet is small, the air inlet quantity is large, and the problem that the air source is easy to yellow flame (caused by oxygen deficiency) can be solved. The shrinkage tube 102 can achieve the function of adjusting the inlet area of primary air to cope with different air sources, and can be solidified to form an inlet state with a certain air quantity.
When the mounting position of the shrinkage tube 102 on the injection tube 101 is adjusted, the positions of the shrinkage tube 102 and the injection tube 101 can be locked by using the fastener 103, so that the shrinkage tube 102 is prevented from moving, and the air inlet amount is more reliably adjusted.
In an alternative scheme of the embodiment, at least one of the shrinkage tube 102 and the injection tube 101 is provided with a strip hole 106, and the length direction of the strip hole 106 is the connecting line direction of the air inlet 104 of the injection tube 101 and the gas nozzle 105; the fastener 103 is mounted at the elongated aperture 106. Namely, the shrinkage tube 102 moves along the length direction of the strip hole 106, so that the shrinkage tube 102 can be close to or far away from the gas nozzle 105, and the fastener 103 can be used for connecting and fixing the shrinkage tube 102 and the injection tube 101 at any position of the strip hole 106.
The position of the gas nozzle 105 is generally located on the axis of the ejector tube 101, and at this time, the length direction of the elongated hole 106 is the axis direction of the ejector tube 101, and the shrinkage tube 102 can reciprocate along the axis direction of the ejector tube 101.
In an alternative to this embodiment, the shrink tube 102 comprises a tube body 107 and a connector 108; the lumen size of the tube body 107 diverges in a direction away from the air inlet 104 of the ejector tube 101. The connection member 108 is located outside the tube main body 107, and the connection member 108 is connected to the tube main body 107. The connecting piece 108 is provided with a strip hole 106, the injection pipe 101 is provided with a fixing hole 109, and the fastening piece 103 is connected with the strip hole 106 and the fixing hole 109. That is, the connection structure of the contraction pipe 102 and the injection pipe 101 does not affect the lumen structure of the pipe main body 107, and the influence on the intake air flow can be reduced.
As shown in fig. 1, the fastener 103 is a screw, and the fixing hole 109 is a screw hole. The fastener 103 penetrates through the strip hole 106 and is in threaded connection with the fixing hole 109, so that the shrinkage tube 102 is installed at the air inlet 104 of the injection tube 101. Preferably, the end of the fastener 103 does not protrude from the inner wall of the ejector tube 101, i.e., the length of the screw is not too long, and the end of the screw does not extend into the ejector tube 101, thereby avoiding the screw from affecting the flow of the air stream.
More specifically, as shown in fig. 4, the connecting member 108 is a bent flange provided at one end of the pipe main body 107 near the gas nozzle 105, that is, the bent flange is provided with a long hole 106 for connecting the injection pipe 101. The bending flanging is bent to the outer side of the pipe main body 107, so that a splicing groove 110 is formed between the pipe main body 107 and the pipe main body, the pipe wall at the air inlet 104 of the injection pipe 101 is spliced in the splicing groove 110, and the reliability of the connection between the shrinkage pipe 102 and the injection pipe 101 can be improved.

The damper adjusting device in the second embodiment is an improvement on the basis of the above embodiment, and the technical content disclosed in the above embodiment is not repeated, and the content disclosed in the above embodiment also belongs to the content disclosed in the second embodiment.
Referring to fig. 2 and 3, in an alternative scheme of the embodiment, a limiting surface 111 is arranged on a pipe wall at an air inlet 104 of the injection pipe 101, and the limiting surface 111 is adapted to a bottom of the plugging groove 110; one end of the strip hole 106, which is close to the gas nozzle 105, is a first limiting end, and when the first limiting end corresponds to the fixing hole 109, the limiting surface 111 is abutted with the bottom of the plugging groove 110.
In this embodiment, as shown in FIG. 2, the shrink tubing 102 may be inserted into the ejector tube 101 to distance the shrink tubing 102 from the gas nozzle 105. When the pipe wall of the air inlet 104 of the injection pipe 101 abuts against the bottom of the insertion groove 110 during the process of inserting the shrink tube 102 into the injection pipe 101, the shrink tube 102 cannot move further, and the shrink tube 102 reaches the limit position farthest from the gas nozzle 105. The insertion end of the shrinkage tube 102 may just contact the shrinkage surface 112 provided on the inner wall of the injection tube 101 or may not contact the inner wall of the injection tube 101.
At this time, the first limiting end of the elongated hole 106 is opposite to the fixing hole 109, and the fastener 103 connects the elongated hole 106 to the fixing hole 109, so that the shrinkable tube 102 is fixed at the position farthest from the gas nozzle 105.
Further, except for the position where the bending flanging is arranged, the rest positions of the pipe main body 107, which are close to one end of the gas nozzle 105, are also provided with the pipe edge 113, when the first limiting end corresponds to the fixing hole 109, the pipe edge 113 abuts against the pipe orifice of the injection pipe 101, so that the shrinkage pipe 102 is prevented from being skewed, and the installation position of the shrinkage pipe 102 can be more accurate.
In an alternative embodiment, the end of the elongated hole 106 away from the gas nozzle 105 is a second limiting end, and when the second limiting end corresponds to the fixing hole 109, at least a portion of the pipe main body 107 is located in the injection pipe 101.
In this embodiment, as shown in FIG. 3, the shrink tubing 102 may be pulled out of the injector tube 101 to bring the shrink tubing 102 into close proximity to the gas nozzle 105. When the end of the elongated hole 106 of the connecting piece 108 away from the gas nozzle 105 corresponds to the fixing hole 109 during the process of pulling the shrink tube 102 out of the injection tube 101, the elongated hole 106 is connected to the fixing hole 109 by the fastener 103, and the shrink tube 102 reaches the extreme position nearest to the gas nozzle 105. At this time, the pipe main body 107 cannot be separated from the air inlet 104 of the injection pipe 101, so that air is prevented from entering the injection pipe 101 through a gap between the pipe main body 107 and the injection pipe 101.
