[0040] Pizza ovens used specifically for making pizza generally use electricity, gas or wood pellets as a source of heat supply. Wood pellets have a special aroma and are small in size and easy to carry. Pizza ovens that use wood pellets as a heat source can make more flavorful pizzas.

[0041] The existing gas pizza oven mainly includes an oven, a hopper, a feeding assembly and a gas assembly. The gas assembly includes an ignition device, a burner and a valve body. The gas flows out through the gas outlet of the burner and is ignited to form a flame. Among them, the burner head is an important component of the burner. The gas enters the burner head through the valve body, mixes with a proper amount of air in the burner head, and flows out through the gas outlet to be ignited by the ignition device.

[0042] At present, the burners used in pellet pizza ovens on the market adopt double-outlet safety valves. Each outlet of the double-outlet safety valve is equipped with a tubular flame-spraying burner head. The gas is exported through two tubular flame-spraying burners and ignited by the ignition device at the outlet of the burner head. Therefore, the flame is relatively concentrated at the two outlets, resulting in incomplete combustion of the pellet fuel and uneven heating in the oven, which affects the flavor of the pizza.

[0043] In view of this, the utility model provides a stove head 100, which is intended to ensure the uniformity and consistency of the temperature in the particle pizza oven.

[0044] See also Figure 1 The utility model discloses a stove head 100, which is used for a pizza oven burner 200. The stove head 100 includes a stove head body 110, an air inlet pipe 120 and an air equalizing nozzle 130. A mixing chamber is formed inside the stove head body 110. An air inlet hole and an air outlet hole connected to the mixing chamber are respectively provided at opposite ends of the stove head body 110 along a first direction, and the area of ​​the air outlet hole is larger than that of the air inlet hole; an air inlet channel is formed inside the air inlet pipe 120, the air inlet pipe 120 is arranged on the stove head body 110, and the air outlet end of the air inlet channel is connected to the air inlet hole; the air equalizing nozzle 130 is arranged on the stove head body 110 and connected to the air outlet hole, and a plurality of air outlet channels 131 extending along the first direction are formed inside the air equalizing nozzle 130, and the air inlet end of each air outlet channel 131 is connected to the mixing chamber.

[0045] The burner head 100 in the utility model conveys the gas and air to the mixing chamber through the air inlet pipe 120 for sufficient mixing, which can ensure that the gas and air are fully mixed, make the combustion more complete, and help to improve the combustion efficiency. The mixed gas is then sprayed out through the multiple air outlet channels 131 arranged side by side in the gas uniformizing nozzle 130, so that the flame after ignition has a larger range. Expanding the flame range can increase the contact area between the flame and the particle fuel, ensuring the sufficient combustion of the particle fuel, thereby improving the consistency and uniformity of the temperature of each area in the pizza oven during the combustion process, avoiding uneven heating of the pizza in the oven, and improving the pizza making flavor.

[0046] Further, in an embodiment of the present application, the furnace head 100 includes a contoured shell 140, and the contoured shell 140 is formed with a furnace head body 110, an air inlet pipe 120, and an air uniforming nozzle 130. The comprehensive design integrates the furnace head body 110, the air inlet pipe 120, and the air uniforming nozzle 130, which can not only improve the overall performance and stability of the furnace body, but also simplify the manufacturing process, reduce the number of parts, and improve production efficiency. The contoured shell 140 can be manufactured using a metal sheet through stamping, stretching, drilling, bending, and other processes to form the metal sheet into a predetermined shape.

[0047] In order to further simplify the manufacturing process, in one embodiment of the present application, the contoured shell 140 includes an upper contoured shell 141 body 140 and a lower contoured shell 142 body 140, and the upper contoured shell 141 body 140 and the lower contoured shell 142 body 140 are connected by riveting to form a mixing chamber, an air inlet channel and a plurality of air outlet channels 131. Specifically, the upper contoured shell 141 body 140 and the lower contoured shell 142 body 140 can be firmly connected by bolt fasteners or snap fasteners, please refer to Figure 1 A snap-fit ​​flange is formed on the edge of the lower contoured shell 142 body 140, and the snap-fit ​​flange is bent to form a snap-fit ​​groove. The edge of the lower contoured shell 142 body 140 is snap-fitted with the snap-fit ​​groove. In order to ensure the stability of the connection, a protrusion is bent on the lower contoured shell 142 body 140. After the lower contoured shell 142 body 140 and the upper contoured shell 141 body 140 are snap-fitted through the snap-fit ​​groove, a bending tool can be used to bend the bent protrusion to abut against the upper contoured shell 141 body 140 to ensure the consistency of the contoured shell 140 structure.

[0048] In order to ensure the uniform distribution of the mixed gas in each gas outlet channel 131, in one embodiment of the present application, the burner body 110 includes a diffuser 111 and a straight-through portion 112 connected to the diffuser 111, an air inlet hole is formed at one end of the diffuser 111 away from the gas equalizing nozzle, and an air outlet hole is formed at one end of the gas equalizing nozzle away from the diffuser 111. In the direction from the air inlet pipe 120 to the gas equalizing nozzle 130, the cross-sectional area of ​​the diffuser 111 gradually increases, and the cross-sectional area of ​​the straight-through portion 112 is adapted to the maximum cross-sectional area of ​​the diffuser 111. This structure can ensure that the fuel gas and air are fully dispersed in the inner cavity of the diffuser 111, so that the fuel and air are fully in contact to form a uniform mixed gas, and the mixed gas is evenly distributed in each gas outlet channel 131 through the straight-through portion 112, and is evenly sprayed at the gas outlet end of the gas equalizing nozzle 130, thereby providing a more stable and efficient combustion effect.

[0049] See also Figures 2 to 5The utility model also provides a pizza oven burner 200, including a burner head 100, a safety valve 210 and an igniter 220. The specific structure of the burner head 100 refers to the above embodiment. The safety valve 210 is arranged at one end of the air inlet pipe 120 away from the burner head body 110, and the air outlet end of the safety valve 210 is connected to the air inlet pipe. The air inlet end of the safety valve 210 is used to connect to an external gas source; the ignition end of the igniter 220 is arranged near the gas nozzle 130, and is used to ignite the gas sprayed from the air outlet end of the air outlet channel 131. Since the pizza oven burner 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0050] It should be added that the safety valve is a combination valve of a plug valve and a solenoid valve. When the manual rotation ignition is successful, the flame heats the front end of the thermoelectric flameout protector to generate current, so that the solenoid valve in the valve body is attracted, thereby ensuring that the gas circuit is always open.

[0051] Furthermore, in one embodiment of the present application, the pizza oven burner 200 further includes a mounting plate 230 disposed on the burner body 110, the extension direction of the mounting plate 230 is arranged at an angle with the first direction, and the mounting plate 230 is provided with a first mounting hole; the igniter 220 is passed through the first mounting hole and is detachably arranged with the mounting plate 230. The igniter 220 is a device for igniting fuel, which is commonly used in burners or other gas equipment, and can provide an ignition source that can generate flames to start the combustion process. The igniter 220 can be an electric spark igniter 220 or an infrared igniter 220. It can be known that in order to ensure the consistency of ignition, the igniter 220 is usually electrically connected to the operating knob of the safety valve 210. When the knob is rotated to the ignition position, the safety valve 210 will open, thereby achieving automatic ignition while controlling the flow of gas.

[0052] Furthermore, in one embodiment of the present application, the pizza oven burner 200 further includes a mounting plate 230 disposed on the burner body 110, the extension direction of the mounting plate 230 is set at an angle with the first direction, and the mounting plate 230 is provided with a second mounting hole; the pizza oven burner 200 further includes a thermoelectric flameout protector 240, the thermoelectric flameout protector 240 is passed through the second mounting hole, and is detachably arranged with the mounting plate 230, the sensing head of the thermoelectric flameout protector 240 is arranged close to the gas nozzle 130, and the thermoelectric flameout protector 240 is electrically connected to the safety valve 210. The working principle of the thermoelectric flameout protector 240 is based on the thermoelectric effect. When the thermoelectric flameout protector 240 senses that the flame temperature at the position of the gas outlet channel 131 is lower than the safe range of the gas combustion temperature (generally the flame is extinguished), the thermoelectric flameout protector 240 will stop generating an electrical signal through the thermoelectric element, the solenoid valve in the safety valve 210 is closed, and the gas path is disconnected to prevent the gas from continuing to leak.

[0053] Of course, in one embodiment of the present application, the first mounting hole and the second mounting hole are arranged on the mounting plate 230 at intervals, and the igniter 220 and the thermal electric flameout protector 240 are installed on the mounting plate 230 at the same time.

[0054] For further information, see Figure 5 , the safety valve 210 has two gas outlet ends, and the pizza oven burner 200 includes two burners 100, and the burner bodies 110 of the two burners 100 are respectively connected to the two gas outlet ends of the safety valve 210. In the pizza oven burner 200, two burners 100 are usually used for combustion. In order to control the combustion of the burners 100, the safety valve 210 is used to connect the burner body 110 and the gas supply pipeline. In this way, by controlling the on-off state of the solenoid valve, the flow control of the fuel can be achieved, thereby controlling the injection process of the burner 100. By using the safety valve 210 with two gas outlet ends, the pizza oven burner 200 can achieve synchronous control of the two burners 100, making the combustion process of the burners 100 more precise and controllable, and can improve the cooking effect and energy utilization of the pizza oven.

[0055] In one embodiment of the present application, the pizza oven burner 200 further includes a gas pipe 250 and a pressure reducing valve 260. The gas outlet end of the gas pipe 250 is connected to the gas inlet end of the safety valve 210, and the gas outlet end of the gas pipe 250 is connected to the external gas source. The pressure reducing valve 260 is arranged on the gas pipe 250 to adjust the gas flow in the gas pipe 250. The gas pipe 250 is used to transport the gas to the safety valve 210, and the pressure reducing valve 260 is used to control the flow and pressure of the gas to ensure that the pizza burner can operate normally. The pressure reducing valve 260 can stabilize the gas pressure in the gas pipe at a fixed value as needed, thereby realizing the control and regulation of combustion to generate the required heat to bake the pizza.

[0056] See also Figure 6 The utility model also provides a gas pizza oven 300, including an oven shell 310 and a pizza oven burner 200. The specific structure of the pizza oven burner 200 refers to the above embodiment. The oven shell 310 is internally formed with a combustion chamber 311 and a baking chamber 312 that are connected; the pizza oven burner 200 is accommodated in the combustion chamber 311. Since the gas pizza oven 300 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0057] To facilitate the addition of pellet fuel, in one embodiment of the present application, the furnace shell 310 is provided with a feed port 313 connected to the combustion chamber 311; the gas pizza oven 300 further includes a combustion support 320 and a hopper 330. The combustion support 320 is tilted at the bottom of the combustion chamber 311, and the hopper 330 is passed through the feed port 313 and is located above the combustion support 320. It is easy to understand that the pellet fuel is put in from the feed port 313, and falls onto the combustion support 320 through the hopper 330. The tilted combustion support 320 facilitates all the pellet fuel to fully react and burn, improves combustion efficiency, and reduces energy waste.
