Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

In the following description, a detailed structure will be presented for a thorough understanding of the embodiments of the present invention. It is apparent that the implementation of the embodiments of the invention is not limited to the specific details known to a person skilled in the art. The preferred embodiments of the present invention are described in detail below, however, the present invention can have other embodiments in addition to the detailed description.

According to an aspect of the present invention, a burner is provided. As shown in fig. 1 to 5, the burner 100 may include a burner 110, an ignition needle 120, and a fixing member 130. The fixing member 130 is used to fix the ignition needle 120 to the burner 110. The burner 110 may be provided with a mounting hole 111. The ignition pin 120 may be inserted through the mounting hole 111. The mounting hole 111 may limit the ignition pin 120 to some extent in a radial direction. A catching groove 121 may be formed on a sidewall of the ignition needle 120. The engaging groove 121 may be located below, in the middle of, or at other positions of the burner 110, which is not limited herein. Hereinafter, an embodiment in which the catching groove 121 is located below the burner 110 will be described as an example. The end 131 of the fixing member 130 may be fixed to the bottom of the burner 110. The middle portion 132 of the fixing member 130 may be retained in the catching groove 121. The fixing member 130 is located below the burner 110. The fixing member 130 may have a plate-like, strip-like, column-like or sheet-like structure. It is understood that the fixing member 130 may be a one-piece structure or a split structure, which is not limited herein, as long as the middle portion 132 of the fixing member 130 can be clamped in the clamping groove 121. The catching groove 121 may be an arc-shaped groove surrounding the ignition needle 120, or an annular groove, etc. The cross section of the card slot 121 may be any shape, for example, the cross section of the card slot 121 may be various shapes and combinations, such as U-shape, V-shape, arc-shape, etc., and is not limited herein. The middle portion 132 of the fixing member 130 may also have any shape, such as U-shape, square shape, V-shape, arc shape, and other shapes and combinations, as long as it can be clamped in the clamping groove 121, and the shape is not limited herein. Illustratively, the middle portion 132 of the fixing member 130 has a cross-sectional shape that is adapted to the catching groove 121, so that the middle portion 132 of the fixing member 130 is more firmly caught to the catching groove 121. The fixing element 130 may be fixed at the bottom of the burner 110 by clamping, adhering, welding, and the like, which is not limited herein. For example, the width of the card slot 121 may be slightly larger than the width of the portion of the fixing member 130 that is clamped into the card slot 121, so that the fixing member 130 can be easily clamped into the card slot 121. For example, when the fixing member 130 has a cylindrical structure, the width of the locking groove 121 may be greater than the diameter of the fixing member 130.

When the ignition needle 120 is installed, the end 131 of the fixing member 130 may be fixed to the bottom of the burner 110, and then the ignition needle 120 may be inserted into the installation hole 111 from top to bottom. When the engaging groove 121 passes through the mounting hole 111, the middle portion 132 of the fixing member 130 can be engaged with the engaging groove 121. In this way, the fixed point fire needle 120 is realized, and the assembly of the burner 100 is completed. It can be understood that, during installation, the ignition needle 120 may be inserted into the installation hole 111, then the middle portion 132 of the fixing member 130 is held in the clamping groove 121, and then the end portion 131 of the fixing member 130 is fixed to the bottom of the burner 110, so as to fix the ignition needle 120 and complete the assembly of the burner 100. The burner 100 is fastened to the ignition needle 120 by a fixing member 130 fixed to the burner head 110, which fixes the ignition needle 120 in a fastening groove 121 of the ignition needle 120, instead of applying all the force to the ignition needle 120 as in the case of the screw fastener or the snap spring of the related art. The inventors have found that either the screw fastener or the circlip are mounted directly on the firing pin 120. In particular, in the case of fixing the ignition needle 120 using a screw fastener, threads need to be machined on the ignition needle 120 and the degree of force applied when screwing the screw fastener is slightly large may cause damage to the ignition needle 120; in the case of fixing the ignition needle 120 by using the snap spring, the snap spring needs to be completely fixed on the ignition needle 120, so the weight of the snap spring itself needs to be borne by the ignition needle 120, and the ignition needle 120 is easily damaged in both cases. And fixing piece 130 is fixed on furnace end 110 in the combustor 100 of this application, the effort that fixing piece 130 applyed to ignition needle 120 only need with ignition needle 120 keep in preset position can, consequently fixing piece 130 can exert less power to ignition needle 120, can greatly reduced ignition needle 120 impaired probability like this, avoid frequently changing ignition needle 120, improved user experience. Moreover, the structure of the burner 100 is simple, the number of parts is small, and the probability of the failure of the burner 100 is reduced. Mounting 130 is located furnace end 110's below, and this mounting 130 can keep away from high temperature stove fire, has avoided receiving the impaired or deformation that high temperature toasted the result in for a long time and can't fix the spot fire needle 120 firmly, and then has reduced the frequency of changing spare part, has reduced the maintenance cost, and user's experience feels better.

Illustratively, as shown in fig. 6, the catching groove 121 may be an annular groove surrounding the ignition needle 120. Compared with other clamping grooves (such as arc-shaped clamping grooves), the annular groove can enable the ignition needle 120 to penetrate into the mounting hole 111 in any direction and be clamped with the fixing piece 130, so that the ignition needle 120 is more convenient to mount.

For example, the inner diameter of the mounting hole 111 may be adapted to the outer diameter of the ignition needle 120. With such an arrangement, the mounting hole 111 can better limit the ignition needle 120 in the radial direction.

Illustratively, the portions of the ignition pins 120 that are located below the mounting holes 111 each have a diameter that is less than or equal to the diameter of the mounting holes 111. With this arrangement, the ignition pin 120 can be inserted into the mounting hole 111 from the top down. When dismantling or changing this combustor 100's ignition needle 120, need not with the help of external instrument, the user can directly upwards pull out ignition needle 120, under the effect of pulling force, draw-in groove 121 breaks away from mounting 130 to dismantle ignition needle 120 from furnace end 110 fast. When the ignition needle 120 is installed, the ignition needle 120 only needs to be inserted into the installation hole 111 downwards, and the installation is very convenient and fast. Also, since the ignition needle 120 can be mounted and dismounted above the burner 110, the operation is more convenient.

For example, as shown in fig. 2 and 7, the middle portion 132 of the fixing member 130 may partially surround the ignition pin 120 and be caught in the catching groove 121. The middle portion 132 of the fixing member 130 may have various shapes such as a square shape, an arc shape, a trapezoid shape, a U shape, etc., as long as it can semi-surround the ignition needle 120, which is not limited herein. Both end portions 131 of the fixing member 130 may be fixed to the bottom of the burner 110. With this arrangement, the middle portion 132 of the fixing member 130 only needs to surround the ignition needle 120 in a region approximately half of its outer circumference and be fitted into the catching groove 121, which simplifies the structure of the fixing member 130, i.e., the structure of the burner 100. The ignition pin 120 is more easily engaged with and disengaged from the catching groove 121 during the mounting and dismounting processes, respectively. Furthermore, both end portions 131 of the fixing member 130 may be fixed to the bottom of the burner 110, and the fixing of the fixing member 130 is more secure than when one end portion 131 is fixed to the burner 110, thereby further fixing the ignition needle 120 better.

Illustratively, the middle portion 132 of the fixing member 130 may have an arc-shaped beam shape. The arc-shaped beam can be in the shape of a semicircle, a major arc or a minor arc, and the like, and is not limited herein. The ignition needle 120 is generally cylindrical. Due to the arrangement, the arc-shaped beam can be better adapted to the structures of most ignition needles 120, and the universality is strong; moreover, the arc beam-shaped middle part 132 has a larger contact area with the ignition needle 120, so that the ignition needle 120 can be firmly fixed on the burner 110, and less space around the ignition needle 120 is occupied, which is beneficial to the miniaturization of the burner 100; furthermore, since the middle part 132 of the fixing member 130 has an arc-shaped beam structure, the middle part 132 of the fixing point fire needle 120 has a certain elasticity, and the fire needle 120 is correspondingly more easily engaged with and disengaged from the engaging groove 121 during installation and removal.

For example, as shown in fig. 2 and 7, the two end portions 131 of the fixing member 130 may extend from the two ends of the middle portion 132 toward opposite directions, respectively. With this arrangement, the two end portions 131 of the fixing member 130 are located on two sides of the mounting hole 111, so that the two end portions 131 can be fixed on two sides of the mounting hole 111. The fixing of the fixing member 130 can be made more uniform. Moreover, the fixing member 130 has a simple structure and is convenient to manufacture. Moreover, compared with the two end portions 131 of the fixing member 130 which can extend from the two ends of the middle portion 132 towards the same direction, the two end portions 131 of the fixing member 130 can have a larger opening degree therebetween, so that the middle portion 132 has better elasticity, and the middle portion 132 can be more conveniently and rapidly clamped in the clamping groove 121.

Illustratively, the fixing member 130 may be made of a metal material, and may be configured to have elasticity. So set up, when plug ignition needle 120, mounting 130 can warp, better block the draw-in groove 121. Illustratively, the fixing member 130 may be made of a spring steel wire.

Illustratively, as shown in fig. 2 and 7, a junction 151 of the middle portion 132 and the end portion 131 of the fixing member 130 may be spaced apart from a junction 152 of the end portion 131 of the fixing member 130 and the burner 110 by a predetermined distance. With such an arrangement, the fixing member 130 has better elasticity at the arc-shaped beam portion, which is more favorable for clamping and separating the middle portion 132 of the fixing member 130 and the clamping groove 121 in the process of mounting and dismounting the ignition needle 120.

Illustratively, the radius of curvature of the curved beam-like central portion 132 may be greater than the radius of curvature of the firing pin 120. With such an arrangement, when the middle portion 132 in the shape of the arc-shaped beam semi-surrounds the ignition needle 120, rubbing against the outer wall of the ignition needle 120 is avoided, thereby affecting the performance of the ignition needle 120. And, when the arc-shaped beam semi-surrounds the ignition needle 120, it is easier and the operation is fast.

The manner in which the fixing member 130 is fixed to the burner 110 is various. Illustratively, the bottom of the burner 110 may be provided with a first stopper groove 113 that is upwardly recessed. The shape of the first limiting groove 113 may be any shape, for example, U-shaped, V-shaped, stepped, etc., as long as it can limit the end 131 of the fixing member 130, and is not limited herein. At least a portion of the end 131 of the fixing member 130 is inserted into the first limiting groove 113. It is understood that the end 131 of the fixing member 130 may be located in the first limiting groove 113, may be flush with the first limiting groove 113, or, as shown in fig. 5, the end 131 of the fixing member 130 may protrude out of the first limiting groove 113. So set up, can directly operate mounting 130 in the bottom of furnace end 110, with the tip 131 of mounting 130 from bottom to top direct embedding to first spacing groove 113 in, fixed mounting 130 and furnace end 110, this structure can make the mode that mounting 130 fixed to furnace end 110 simple and convenient more.

Illustratively, as shown in fig. 2, 4, 5 and 7, a bending segment 133 may be connected to an end 131 of the fixing member 130. The bottom of the burner 110 may be provided with a second catching groove 112 that is upwardly recessed. At least a portion of the bending segment 133 can be received in the second limiting groove 112. The shape of the second limiting groove 112 may be any shape, for example, U-shaped, V-shaped, stepped, etc., as long as it can limit the bending section 133 of the fixing member 130, which is not limited herein. The extending direction of the second limiting groove 112 is different from the extending direction of the first limiting groove 113. It is understood that the extending direction of the second limiting groove 112 may or may not be perpendicular to the extending direction of the first limiting groove 113, and is not limited herein. So set up, when first spacing groove 113 is spacing to the tip 131 of mounting 130, second spacing groove 112 can be spacing to the section 133 of bending of mounting 130 simultaneously, and, second spacing groove 112 can be spacing to mounting 130 in the spacing direction that is different from first spacing groove 113, that is to say, furnace end 110 can carry out spacing in two at least directions to mounting 130, avoided the removal of mounting 130 along the extending direction of first spacing groove 113 in furnace end 110 bottom, further make fixing 130 more firm with furnace end 110's fixed.

As shown in fig. 3, the combustor 100 may also include a platen 140. The pressing plate 140 may be fixed to the burner 110 and cover the notch of the first catching groove 113 to fix the end 131 of the fixing member 130 to the burner 110. The manner in which the pressure plate 140 is fixed to the burner 110 is various, and for example, the pressure plate may be fixed to the burner 110 by using threads, pins, snaps, etc., which are not limited herein. In one embodiment, the pressure plate 140 and the burner 110 may be provided with corresponding threaded holes, and the pressure plate 140 is fixed to the burner 110 by fasteners. When the fixing member 130 is installed, at least a portion of the end 131 of the fixing member 130 may be first inserted into the first limiting groove 113, and then the pressing plate 140 may be fixed to the burner 110. With such an arrangement, the fixing member 130 can be more stably fixed, and the fixing member 130 is prevented from slipping off the burner 110.

Illustratively, as shown in fig. 2 and 3, the pressure plate 140 may be provided with a through hole 141 aligned with the mounting hole 111. The ignition needle 120 may be inserted through the through hole 141. The inner diameter of the through hole 141 is adapted to the outer diameter of the ignition needle 120. With such an arrangement, the mounting hole 111 on the burner 110 and the through hole 141 on the pressing plate 140 respectively radially limit the ignition needle 120 above and below the fixing member 130, so that even if the fixing member 130 is only half-enclosed and clamped into the clamping groove 121 on the ignition needle 120, the ignition needle 120 can be prevented from shaking in the horizontal direction and being separated from the fixing member 130. The fixing member 130 may axially limit only the ignition pin 120. Thus, the force applied to the ignition pin 120 by the fixing member 130 can be further reduced, thereby extending the life of the ignition pin 120.

Illustratively, at least a portion of the end 131 of the fixing member 130 may have a gap with an inner wall of the first limiting groove 113. It is understood that the width of the first limiting groove 113 may be slightly greater than the width of the portion of the end 131 of the fixing member 130 inserted into the first limiting groove 113. The height dimension of the first limiting groove 113 may be slightly greater than the height of the portion of the end 131 of the fixing member 130 inserted into the first limiting groove 113. When the fixing member 130 is inserted into the first limiting groove 113, the fixing member 130 is forced to deform, and the gaps can provide a moving space for the portion of the end 131 of the fixing member 130 inserted into the first limiting groove 113 to deform.

For example, as shown in fig. 1 and 6, a boss 122 may be provided on a sidewall of the ignition needle 120. The boss 122 may abut against an edge of the mounting hole 111 above the burner 110. The boss 122 may have any shape, such as a square, a hexagon, an ellipse, etc., and is not limited herein. So set up, boss 122 can play spacing effect, avoids the downward aversion of ignition needle 120. And, during the installation point fire needle 120, can play the effect of preliminary location, avoided the operation that the ignition needle 120 excessively deeply inserted mounting hole 111 and then upwards drawn back again for first operation just can accurate location during installation point fire needle 120, avoided adjusting the position repeatedly, simplified assembly process, labour saving and time saving.

Illustratively, as shown in fig. 6, the boss 122 may be an annular boss. By such arrangement, the annular boss can cover the mounting hole 111, so that dirt is prevented from flowing into the lower portion of the burner 110 from the mounting hole 111. And the annular boss can limit the ignition needle 120 in the whole circumferential direction, so that the inclination of the ignition needle 120 is avoided.
