TECHNICAL FIELD
[0001] The utility model relates to a gas pizza oven technical field, concretely relates to a gas stove head and gas pizza oven. BACKGROUND
[0002] The existing gas pizza oven is provided with a gas stove head in the furnace body. In the first minute or so of combustion, before the gas pressure reaches balance, the gas stove head is prone to produce off-flame and floating flame, and the flame back suction is prone to produce backfire when the flame is extinguished.
[0003] The specific performance shows the following problems:
[0004] 1. The gas directly hits the fire hole position corresponding to the gas inlet end of the stove head, which is easy to cause off-flame;
[0005] 2. The gas collides with the wall on both sides of the stove head and forms a nest flow, the local gas gathering pressure is large, and off-flame is easy to occur;
[0006] 3. The inner cavity space of the cast iron stove head is large, and it is easy to cause backfire noise when the flame is extinguished. INVENTION CONTENTS
[0007] The utility model aims at providing a gas stove head which solves the problem of off-flame at the gas inlet end of the stove head.
[0008] The utility model is realized in this way.
[0009] A gas stove head, comprising a stove head body, the stove head body is provided with an air inlet section, the stove head body is provided with a fire hole along the air inlet section to the end of the stove head body, the stove head body is provided with a stove cavity communicating with the fire hole, and the length of the fire hole on the air inlet section is greater than that of the fire hole in the remaining area.
[0010] The utility model increases the length of the air inlet section fire hole, when the gas directly hits the fire hole at this position, the corresponding fire hole gas outlet pressure is relatively stable under the influence of the longer channel of the fire hole, and the off-flame phenomenon of the gas stove head air inlet section is avoided.
[0011] Further, the thickness of the stove wall where the air inlet section is located is greater than that of the stove wall where the remaining fire holes are located.
[0012] By increasing the thickness of the air inlet section stove wall, the length of the air inlet section fire hole is lengthened, which is easy to manufacture, simple in structure and stable.
[0013] Further, the thickness of the stove wall where the air inlet section is located is 2 to 3 times that of the stove wall where the remaining fire holes are located.
[0014] It is helpful to relatively balance and stabilize the fire hole pressure of the air inlet section and the end of the stove head body.
[0015] Further, the stove cavity in the stove wall where the air inlet section is located is thickened.
[0016] The overall volume of the gas burner head is not increased.
[0017] Further, the furnace cavity space gradually decreases from the gas inlet section to the end of the burner head body.
[0018] The furnace cavity space is largest at the gas inlet section and gradually decreases to the end of the burner head body. By changing the size of the furnace cavity space, the gas is guided to flow reasonably in the furnace cavity, avoiding the formation of swirling flow at the end of the burner head body, reducing the local gas pressure difference, and thereby reducing the occurrence of flame deviation of the flame hole at the end of the burner head body.
[0019] Further, the middle part of the burner head body is the gas inlet section, and the middle part of the burner head body extends to the left and right to form the end of the burner head body.
[0020] A gas pizza oven comprises a furnace body, and the furnace body is provided with the above-mentioned gas burner head.
[0021] The gas burner head is used in the gas pizza oven, and the use is safer and more reliable.
[0022] The length of the gas inlet section flame hole is increased, and when the gas directly hits the flame hole at this position, the corresponding flame hole gas outlet pressure is relatively stable due to the influence of the longer channel of the flame hole, thereby avoiding flame deviation at the gas inlet section of the gas burner head. The furnace cavity space is largest at the gas inlet section and gradually decreases to the end of the burner head body. By changing the size of the furnace cavity space, the gas is guided to flow reasonably in the furnace cavity, avoiding the formation of swirling flow at the end of the burner head body, reducing the local gas pressure difference, and thereby reducing the occurrence of flame deviation of the flame hole at the end of the burner head body. The overall structure is simple, reasonable in design, and easy to manufacture. BRIEF DESCRIPTION OF DRAWINGS

[0028] The utility model will be further described below in combination with the drawings and embodiments.
[0029] Embodiment one, seeFigures 2-5 As shown in the figure, a gas stove head comprises a stove head body 1, a middle part of the stove head body 1 is the gas inlet section 2, the gas inlet section 2 is provided with a gas inlet 21, and the middle part of the stove head body 1 extends to the end of the stove head body 1 on both sides.
[0030] The stove head body 1 is provided with a fire hole 3 on both sides from the gas inlet section 2 to the end of the stove head body 1. The length of the fire hole 3 on the gas inlet section 2 is greater than that of the fire hole 3 in the remaining area. Specifically, the thickness of the stove wall where the gas inlet section 2 is located is greater than that of the stove wall where the remaining fire holes 3 are located. Preferably, the thickness of the stove wall where the gas inlet section 2 is located is 2 to 3 times that of the stove wall where the remaining fire holes 3 are located, and the stove cavity 4 in the stove wall where the gas inlet section 2 is located is thickened.
[0031] The stove head body 1 is provided with a stove cavity 4 communicating with the fire hole 3, and the stove cavity 4 communicates with the gas inlet 21. The space of the stove cavity 4 gradually decreases from the gas inlet section 2 to the end of the stove head body 1 on both sides, and the shape of the stove cavity 4 is as shown in the figure.
[0032] The gas enters the stove cavity 4 through the gas inlet 21, and the fire hole 3 on the gas inlet section 2 directly faces the gas. Since the length of the fire hole 3 at this position is relatively long, the gas outlet pressure of the fire hole 3 is reduced, the pressure of the fire hole 3 is more stable, and flame deviation is not easy to occur. The gas flows in the stove cavity 4 from the gas inlet section 2 to the end of the stove head body 1 on both sides. Since the space of the stove cavity 4 gradually decreases, the gas is not easy to produce a swirling flow at the end of the stove head body 1, the gas pressure at this position is reduced, and the fire hole 3 at the end of the stove head body 1 is not easy to produce flame deviation. The overall space of the stove cavity 4 of the stove head body 1 is reduced. Compared with the existing gas stove head, under the same volume, the unburned gas pre-existing in the stove cavity 4 of the stove head body 1 of the utility model is relatively reduced, and the noise of flameout and explosion is relatively smaller.
[0033] Referring to Figure 1 As shown in the figure, a gas pizza stove comprises a stove body 5, and the stove body 5 is provided with the above-mentioned gas stove head. The gas pizza stove is not easy to produce flame deviation and backfire.

[0035] As used in the present utility model, the terms "one", "a", etc. do not represent a limitation on the quantity, but represent the existence of at least one mentioned object.
