Description

Technical Field

[0001] The utility model relates to the technical field of stove burners, in particular to a burner base. Background Art

[0002] The stove burner plays a pivotal role in modern families. The temperature required for cooking is largely due to the combustion performance of the stove burner. In the prior art, the stove burner generally includes a base, a burner, a fire cover and an ignition needle. During use, the base is usually connected to a gas pipe so that the gas is premixed between the base and the burner before entering the burner for output and combustion.

[0003] For example, Chinese patent document CN107036093A discloses a three-ring fire burner that is easy to disassemble, which discloses that the furnace base is provided with an outer ring fire channel connected to the outer ejector tube, a middle ring fire channel connected to the middle ejector tube, and an inner ring fire channel connected to the inner ejector tube; the outer ring fire channel is connected to the outer ring air channel, the middle ring fire channel is connected to the middle ring air channel, respectively, and the inner ring fire channel is connected to the inner ring air channel.

[0004] The stove base of the prior art is provided with three channels to connect the three ejector tubes of the burner. This structure usually can only make the inner ring fire and the center fire burn at the same time. However, in actual cooking, only turning on the center fire will cause the temperature of the outer ring position at the bottom of the pot to drop, making the heating of the pot uneven. In addition, the structure of this stove base is relatively bulky and the manufacturing cost is high. Utility Model Content

[0011] In the above-mentioned burner base, a second gas inlet installed on the chassis is provided on one side of the first gas inlet, and the second gas inlet is connected to an inner fire ring gas outlet, and the inner fire ring gas outlet is located on one side of the outer fire ring gas outlet.

[0012] The beneficial effect of the utility model is that gas is supplied to the outer fire ring gas outlet and the center fire nozzle mounting seat at the same time through the first gas inlet on the chassis, so that the outer fire ring and the center fire can be turned on at the same time, and the outer ring and the center ring of the bottom of the cookware can be heated during cooking, with high heating efficiency and uniform heating, without the need to adopt the traditional three channels, reducing the structure and weight of the chassis, and having relatively lower manufacturing costs, and the center fire nozzle mounting seat can be used to install the center fire nozzle, making overall maintenance convenient.

DETAILED DESCRIPTION

[0017] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0018] Combination Figures 1 to 3 A burner base shown includes a chassis 1, a first gas inlet 3 is provided at the lower end of one side of the chassis 1, an outer fire ring gas outlet 9 connected with the first gas inlet 3 is provided on one side of the upper end of the chassis 1, a center fire nozzle mounting seat 6 is provided in the middle of the chassis 1, the center fire nozzle mounting seat 6 is connected with the first gas inlet 3 through a connecting pipe 5, and the center fire nozzle mounting seat 6 is located at the lower end of the chassis 1; the beneficial effect of the utility model is that by simultaneously supplying gas to the outer fire ring gas outlet 9 and the center fire nozzle mounting seat 6 through the first gas inlet 3 on the chassis 1, the outer fire ring and the center fire can be turned on at the same time, and the outer ring and the center ring at the bottom of the cookware can be heated during cooking, with high heating efficiency and uniform heating, without the need to adopt the traditional three channels, reducing the structure and weight of the chassis 1, and having a relatively lower manufacturing cost, and the center fire nozzle mounting seat 6 can be used to install the center fire nozzle, and the overall maintenance is convenient.

[0019] In this embodiment, one side of the first gas inlet 3 is provided with a second gas inlet 4 installed only on the chassis 1. The second gas inlet 4 is connected to an inner fire ring gas outlet 11. The inner fire ring gas outlet 11 is located on one side of the outer fire ring gas outlet 9, so that only these two gas inlets are required on the chassis 1, reducing the manufacturing cost of the chassis 1.

[0020] The upper end surface of the center fire nozzle mounting seat 6 of the present embodiment is provided with a slag receiving groove 7, and a center fire nozzle mounting hole 8 is provided in the slag receiving groove 7. The center fire nozzle mounting hole 8 is connected with the connecting pipe 5, and the inner wall of the center fire nozzle mounting hole 8 is provided with an internal thread. The center fire nozzle mounting hole 8 is used to install the center fire nozzle. The center fire nozzle is cylindrical, and the outer wall is provided with an external thread. A spray hole is opened at the upper end of the center fire nozzle. After installation, the gas can be directly output from the center fire nozzle mounting hole 8, and then sprayed upward from the spray hole, which can make the center fire ring structure of the burner simpler. The connecting pipe 5 and the core fire nozzle mounting seat 6 of the present embodiment are an integrated structure, which makes the entire chassis 1 simpler and more convenient for maintenance.

[0021] A branch air cavity 10 is provided in the connecting pipe 5 of the present embodiment, and one end of the branch air cavity 10 is connected to the first gas inlet 3, and the other end is connected to the center fire nozzle mounting hole 8. The first gas inlet 3 and the connecting pipe 5 are an integrated structure; the gas enters from the first gas inlet 3, and can be simultaneously output from the outer fire ring gas output port 9 and the branch air cavity 10, thereby realizing the simultaneous combustion of the outer fire ring and the center fire. The overall structure is more stable, and leakage at the connection between the outer fire ring gas output port 9 and the branch air cavity 10 is prevented, making it safer to use.

[0022] It should be noted that, in this embodiment, at least two supporting feet 2 are provided at the lower end of the edge of the chassis 1, so that air can easily enter the lower end of the chassis 1. A ventilation hole is opened in the middle of the chassis 1, and the center fire nozzle mounting seat 6 is located in the ventilation hole. Air can enter from the ventilation hole, which is convenient for secondary oxygen supply when the center fire is burning.

[0023] It is also worth mentioning that in some other embodiments, the connecting pipe 5 can also be connected to the second gas inlet 4 without being connected to the first gas inlet 3, and the connecting pipe 5 and the second gas inlet 4 are an integrated structure, thereby achieving simultaneous combustion of the inner fire ring and the center fire.

[0024] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
