Description

Technical Field

[0001] The utility model belongs to the technical field of burners, and particularly relates to a burner for a barbecue grill. Background Art

[0002] With the continuous development of cities, the pressure on people working and living in cities is also increasing continuously. To relieve the pressure, many people will choose to go for an outing and camping outdoors with their friends and family in their spare time. Barbecue is not only convenient and fast, but also can bring everyone camping together. Therefore, a portable barbecue grill has gradually become an indispensable equipment for camping;

[0003] Since camping is basically carried out outdoors and the power supply outdoors is usually difficult to guarantee, most current portable barbecue grills use charcoal or gas for combustion. Taking a gas barbecue grill as an example, the current portable barbecue grills on the market usually have a perforated gas pipeline laid at the bottom of the grill. After the gas is passed through, it is ignited by a blowtorch for barbecue. Although it is convenient and easy to use, at the same time, due to its simple structure, it is difficult for the gas to burn fully, resulting in a large amount of smoke and more gas waste.

[0004] Therefore, we propose a burner for a barbecue grill to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the prior art, and a burner for a barbecue grill is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A burner for a barbecue grill includes an upper layer piece and a lower layer piece. The upper layer piece and the lower layer piece are buckled together. One end of the upper layer piece is provided with an upper half opening, and one end of the lower layer piece is provided with a lower half opening. The combined upper half opening and lower half opening form a complete air inlet. A upper flow guide plate is provided on the side wall of the upper layer piece away from the lower layer piece. An air inlet taper is communicated between the upper half opening and the upper flow guide plate. A lower flow guide plate is provided on the side wall of the lower layer piece away from the upper layer piece. An air inlet taper is also communicated between the lower flow guide plate and the lower half opening. Reverse taper air outlet holes are respectively provided on both side walls of the upper layer piece, and positive taper air outlet holes are respectively provided on both side walls of the lower layer piece.

[0008] Preferably, the cross-sectional shape of the upper layer piece is the same as that of the lower layer piece.

[0009] Preferably, an air inlet alignment member is embedded in the upper half opening and the lower half opening. The side wall of the air inlet alignment member abuts against the inner walls of the upper half opening and the lower half opening, and air inlet holes are provided on the side wall of the air inlet alignment member.

[0010] Preferably, the reverse taper air outlet is arranged obliquely downward, and the positive taper air outlet is arranged obliquely upward.

[0011] Preferably, a barb catch is fixedly connected to the side wall of the upper layer sheet away from one end of the upper half opening, and a clamping groove is fixedly connected to the side wall of the lower layer sheet away from one end of the lower half opening, and the side wall of the barb catch abuts against the inner wall of the clamping groove.

[0012] In summary, the technical effects and advantages of the present utility model are as follows:

[0013] By arranging an upper half opening, a lower half opening, an air inlet guiding member, an air inlet taper, a reverse taper air outlet and a positive taper air outlet between the upper layer sheet and the lower layer sheet, after the gas enters from the air inlet hole of the air inlet guiding member, under the action of the Venturi effect, it will quickly enter the flow guiding plate and be fully mixed with air, making the combustion efficiency higher, and then being ejected from the tapered air outlet, making the air outlet fast and the combustion effect better.

Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Such as Figure 1 - Figure 3As shown in the figure, a barbecue burner includes an upper layer sheet 1 and a lower layer sheet 2. The upper layer sheet 1 and the lower layer sheet 2 are buckled together. The shape of the cross-section of the upper layer sheet 1 is the same as that of the cross-section of the lower layer sheet 2. The same shape enables the two to fit together better, effectively preventing air leakage. One side wall of the upper layer sheet 1 far from the upper half opening 3 is fixedly connected with an inverted hook position 12, and one side wall of the lower layer sheet 2 far from the lower half opening 4 is fixedly connected with a clamping groove 13. The side wall of the inverted hook position 12 abuts against the inner wall of the clamping groove 13. The cooperation of the inverted hook position 12 and the clamping groove 13 enables the upper layer sheet 1 to be easily buckled with the lower layer sheet 2, thereby ensuring that the gas can only be ejected from the two tapered air outlets.

[0020] One end of the upper layer sheet 1 is provided with an upper half opening 3, and one end of the lower layer sheet 2 is provided with a lower half opening 4. The buckled upper half opening 3 and lower half opening 4 are combined into a complete air inlet. The upper half opening 3 and the lower half opening 4 can fit perfectly to ensure that the gas will not leak from the gap between the two. An air inlet guiding and aligning member 10 is embedded in the upper half opening 3 and the lower half opening 4. The side wall of the air inlet guiding and aligning member 10 abuts against both the inner wall of the upper half opening 3 and the inner wall of the lower half opening 4. An air inlet hole 11 is provided on the side wall of the air inlet guiding and aligning member 10. The gas will enter the entire burner through the air inlet hole 11. Since the air inlet hole 11 is relatively small, the gas can enter the burner more concentratedly.

[0021] One side wall of the upper layer sheet 1 far from the lower layer sheet 2 is provided with an upper guide plate 5. An air inlet taper 6 is communicated between the upper half opening 3 and the upper guide plate 5. One side wall of the lower layer sheet 2 far from the upper layer sheet 1 is provided with a lower guide plate 7. An air inlet taper 6 is also communicated between the lower guide plate 7 and the lower half opening 4. The air inlet taper 6 is mainly set to utilize the Venturi effect to accelerate the gas flow rate.

[0022] The Venturi effect means that when a restricted flow passes through a reduced cross-sectional area of the flow passage, the fluid will show an increase in flow velocity. Therefore, after the gas passes through the relatively narrow air inlet taper 6, the flow velocity will increase. The settings of the upper guide plate 5 and the lower guide plate 7 will also make the space inside the burner larger, facilitating the accommodation of more gas and also facilitating the mixing of gas and air. Anti-taper air outlets 8 are respectively provided on both side walls of the upper layer sheet 1, and positive-taper air outlets 9 are respectively provided on both side walls of the lower layer sheet 2. The anti-taper air outlets 8 are inclined downward, and the positive-taper air outlets 9 are inclined upward. The positive-taper air outlets 9 and the anti-taper air outlets 8 are just buckled together, so that the gas mixture can only flow out from the gap between the two. This burner needs to barbecue the food above after being lit, so the length of the positive-taper air outlet 9 is greater than the length of the anti-taper air outlet 8, so that the ignited flame will burn obliquely upward. Due to the small gap between the positive-taper air outlet 9 and the anti-taper air outlet 8, under the action of the Venturi effect, the flow velocity of the gas mixture becomes faster, so that the ignited flame can be ignited more quickly, which is more convenient for the user to use.

[0023] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
