Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gas equipment, specifically to a gas burner head with good gas equalization effect. Background Technology
[0002] Patent document CN206904974U discloses a novel burner, the specific contents of which include "the upper cover and the lower cover of the distribution channel are combined to form an outer ring gas distribution channel, and the outer ring gas outlet groove, the outer ring gas distribution channel and the outer ring gas chamber are connected for combustion".
[0003] As can be seen from the attached diagram, the outer ring gas distribution channel is arranged radially. Therefore, when the gas mixture enters the outer ring gas chamber through the outer ring gas distribution channel, the gas mixture cannot generate a tendency to move circumferentially within the outer ring gas chamber. As a result, the gas mixture will be relatively concentrated near the outlet position of the corresponding outer ring gas distribution channel within the outer ring gas chamber, resulting in a relatively poor uniformity effect in the outer ring gas chamber.
[0004] Therefore, further improvements are needed. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a gas burner head with good gas uniformity. After the gas mixture enters the outer ring gas cavity through the gas delivery channel, it can generate a circumferential movement tendency, so that the gas mixture can better diffuse in the outer ring gas cavity and avoid the situation where the gas mixture is relatively concentrated near the gas outlet end of the gas delivery channel, so that the gas mixture in the outer ring gas cavity has a better gas uniformity effect.
[0006] The purpose of this utility model is achieved as follows:
[0007] A gas burner head with good gas equalization effect includes a flame distribution seat, the flame distribution seat has a first gas distribution chamber, the first gas distribution chamber includes a front gas chamber and an outer ring gas chamber, and a plurality of gas delivery channels are provided between the front gas chamber and the outer ring gas chamber for transporting gas from the front gas chamber to the outer ring gas chamber. The extension line of the gas delivery channel on the side away from the outer ring gas chamber is offset from the dot position of the front gas chamber.
[0008] As a specific embodiment, the width of the gas delivery channel increases along the direction from the front gas chamber to the outer annular gas chamber.
[0009] As a specific embodiment, the gas delivery channel is inclined from bottom to top along the direction from the front gas chamber to the outer ring gas chamber.
[0010] As a specific embodiment, the gas delivery channels are evenly distributed circumferentially along the first gas distribution chamber.
[0011] As a specific embodiment, the ignition base has several partitions distributed on it. The partitions are located between adjacent gas supply channels. An air replenishment hole is provided on the inner side of the partition. The air replenishment hole extends vertically through the upper and lower ends of the ignition base.
[0012] As a specific embodiment, the upper side of the ignition base is provided with an outer ring flame cap, and the outer ring flame cap and the ignition base are connected and fixed by a stud mechanism to form an outer ring gas cavity, with the stud mechanism located inside the outer ring gas cavity.
[0013] As a specific embodiment, the flame distribution base also has a central gas chamber, which passes through the front gas chamber and is spaced apart from each other. A central flame cap is connected to the upper side of the flame distribution base corresponding to the central gas chamber.
[0014] As a specific embodiment, the flame distribution seat is provided with a raised rib at the position corresponding to the central gas chamber. The raised rib is placed horizontally at the gas outlet end of the central gas chamber, and the central flame cover is connected and fixed to the raised rib by a locking device.
[0015] The beneficial effects of this utility model are:
[0016] After the gas mixture enters the outer annular cavity through the gas delivery channel, it tends to move circumferentially, allowing the gas mixture to diffuse better in the outer annular cavity. This avoids the gas mixture from being relatively concentrated near the outlet end of the gas delivery channel, resulting in better gas homogenization in the outer annular cavity.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] See Figures 1-4This gas burner head with good gas equalization effect includes a burner base 1, which has a first gas distribution chamber 11. The first gas distribution chamber 11 includes a front gas chamber 111 and an outer ring gas chamber 112. Several gas delivery channels 113 are provided between the front gas chamber 111 and the outer ring gas chamber 112 to transport gas from the front gas chamber 111 to the outer ring gas chamber 112. The extension line of the gas delivery channel 113 on the side facing away from the outer ring gas chamber 112 is offset from the dot position of the front gas chamber 111. Since the extension direction of the gas delivery channel 113 is not outward... The radial direction of the annular cavity 112 means that after the gas mixture enters the outer ventilation cavity, it will move a certain distance circumferentially before contacting the inner wall of the outer ventilation cavity. This allows the gas mixture to move circumferentially after entering the outer annular cavity 112 through the gas delivery channel 113, enabling the gas mixture to diffuse better in the outer annular cavity 112. This avoids the gas mixture being relatively concentrated near the outlet end of the gas delivery channel 113, resulting in better gas homogenization in the outer annular cavity 112.
[0023] Furthermore, the width of the gas delivery channel 113 increases along the direction from the front gas chamber 111 to the outer ring gas chamber 112, further enhancing the tendency of the gas mixture to diffuse outward when it enters the outer ring gas chamber 112, and further optimizing the gas homogenization effect of the gas mixture in the outer ring gas chamber 112.
[0024] Furthermore, the gas delivery channel 113 is inclined from bottom to top along the direction from the front gas chamber 111 to the outer ring gas chamber 112, so that the gas mixture has a certain upward diffusion tendency after entering the outer ring gas chamber 112, and the gas uniformity effect in the vertical space of the outer ring gas chamber 112 is better.
[0025] Furthermore, the gas delivery channels 113 are evenly distributed along the circumference of the first gas distribution chamber 11, so that the gas mixture can enter the outer annular gas chamber 112 more evenly through different gas delivery channels 113, thereby further improving the gas uniformity effect of the gas mixture in the outer gas exchange chamber.
[0026] Furthermore, the burner seat 1 has several partitions 114 distributed on it. The partitions 114 are located between adjacent gas supply channels 113. The inner side of the partitions 114 is provided with air supply holes 115. The air supply holes 115 penetrate vertically through the upper and lower ends of the burner seat 1, which can supplement more air when the burner head is burning, so that the combustion effect of the burner head is more complete.
[0027] Furthermore, an outer ring flame cap 2 is provided on the upper side of the burner seat 1. The outer ring flame cap 2 and the burner seat 1 are connected and fixed by a stud mechanism 21 to form an outer ring gas cavity 112. The stud mechanism 21 is set in the outer ring gas cavity 112. The stud mechanism 21 can improve the connection strength between the outer ring flame cap 2 and the burner seat 1. At the same time, when the gas mixture flows through the stud mechanism 21 in the outer ring gas cavity 112, the stud mechanism 21 can play a certain turbulence effect on the gas mixture, so that the gas mixture can be further fully mixed, thereby further improving the combustion effect of the burner head.
[0028] Furthermore, the burner seat 1 also has a central gas chamber 12, which passes through the front gas chamber 111 and is spaced apart from each other. The burner seat 1 is connected to a central flame cover 3 on the upper side of the central gas chamber 12, so that the burner head also has the effect of central flame combustion.
[0029] Furthermore, a raised rib 121 is provided on the ignition base 1 at the position corresponding to the central gas chamber 12. The raised rib 121 is horizontally placed at the gas outlet end of the central gas chamber 12. The central burner cap 3 and the raised rib 121 are connected and fixed by a locking device. The raised rib 121 can not only improve the stability of the connection between the central burner cap 3 and the ignition base 1, but also play a certain role in shielding and diverting the gas mixture, so that the gas mixture can diffuse more quickly between the central gas chamber 12 and the central burner cap 3, thereby improving the gas uniformity effect of the central gas chamber 12.
[0030] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
