Description
Technical Field
[0001] This utility model relates to the field of stove technology, specifically to a stove head. Background Technology
[0002] Stoves are commonly used heating devices in households. As long as energy is provided, they can be used to cook food and boil water. With the advancement of transportation and the acceleration of people's pace of life, people often go out for picnics and outings. Consumers who like outdoor travel or camping have an increasing demand for small and portable cooking devices.
[0003] However, existing multi-burner burners require adjustment of flame size and combustion mode during use. They are generally divided into inner ring burners or all burners burning simultaneously. Adjusting these two modes requires a valve structure, but the existing valve structure is complex, and when switching between different modes, it is easy to encounter situations where the flame size is difficult to control. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a furnace head.
[0005] The technical solution of this utility model is as follows:
[0006] This utility model provides a stove head, including a base. An air inlet is opened on one side of the base, and a valve plug hole is opened on the other side of the base corresponding to the position of the air inlet. A valve plug is movably installed in the valve plug hole along the length direction. The valve plug hole and the air inlet are connected through a connecting hole. A first burner head assembly is installed at the middle position of the upper part of the base, and several second burner head assemblies are installed on the outer periphery of the upper part of the base. A first air passage is opened in the base. The lower end of the first air passage is connected to the inner end of the valve plug hole, and the upper end of the first air passage is connected to the first burner head assembly. A second air passage is opened in the base. The lower end of the second air passage is connected to the middle position of the valve plug hole, and the upper end of the second air passage is connected to the multiple second burner head assemblies.
[0007] Furthermore, a first sealing ring is installed on the inner end of the valve plug. When the valve plug extends to the inner limit position, the first sealing ring is located between the inner end of the first air passage and the inner end of the second air passage, and the first sealing ring is in contact with the inner wall of the valve plug hole.
[0008] Furthermore, the valve plug orifice is a stepped orifice, with the inner section diameter being smaller than the middle section diameter. The first sealing ring is installed at the position corresponding to the inner section of the valve plug. When the valve plug extends to the inner limit position, the first sealing ring fits against the inner wall of the inner section.
[0009] Furthermore, a second sealing ring is installed in the middle of the valve plug. The second sealing ring fits snugly against the inner wall of the middle section and is located between the inner end of the second air passage and the outer end of the valve plug hole.
[0010] Furthermore, an internal thread is provided on the outer section of the valve plug hole, and an external thread is provided on the outer end of the valve plug, so that the valve plug and the valve plug hole are connected by threads.
[0011] Furthermore, the outer end of the valve plug is provided with an extension rod.
[0012] Furthermore, a knob is provided at the outer end of the extension rod.
[0013] Furthermore, the base includes a lower base and an upper base. The first air passage and the second air passage are both opened inside the lower base. The upper base is fitted onto the upper end of the lower base. The upper base is provided with multiple support arms. The first flame head assembly is installed on the upper end of the lower base. Multiple second flame head assemblies are respectively installed on the upper side of the outer end of the corresponding support arm. A third air passage is opened inside the support arm. The inner ends of the multiple third air passages are interconnected and connected to the upper end of the second air passage.
[0014] Furthermore, the inner end of the valve plug is a tapered part, and the connecting hole is a tapered hole that matches the shape of the tapered part. When the valve plug is extended to the inner limit position, the tapered part closes the tapered hole.
[0015] The beneficial effects achieved by this utility model are as follows:
[0016] This invention allows for convenient adjustment of the gas supply path and combustion mode through the cooperation of the valve plug, valve plug hole, first gas passage, and second gas passage. Due to the cooperation of the conical part and the conical connecting hole, the maximum air intake rate of the connecting hole can be different between the first combustion mode and the second combustion mode. That is, the air intake rate increases linearly as the valve plug moves outward. This avoids the flame of the first burner assembly from suddenly becoming too small when switching from the first combustion mode to the second combustion mode, and also avoids the flame of the first burner assembly from suddenly becoming too large when switching from the second combustion mode to the first combustion mode. This solves the problem of difficult flame size control when switching combustion modes, making it safer and more reliable to use. Attached Figure Description

[0026] like Figures 1-6 As shown, this utility model provides a stove head, including a base 1. An air inlet 2 is opened on one side of the base 1, and the air inlet 2 is connected to one end of an air inlet pipe 3. A valve plug hole 4 is opened on the other side of the base 1 corresponding to the position of the air inlet 2. A valve plug 5 is movably installed in the valve plug hole 4 along its length. The valve plug hole 4 and the air inlet 2 are connected through a connecting hole 6. A first burner head assembly 7 is installed at the middle position of the upper part of the base 1. There can be one or more first burner head assemblies 7. Several second burner head assemblies 8 are installed on the outer periphery of the upper part of the base 1. A first air passage 9 is opened inside the base 1. The lower end of the first air passage 9 is connected to the inner end of the valve plug hole, and the upper end of the first air passage 9 is connected to the first burner head assembly 7. A second air passage 10 is opened inside the base. The lower end of the second air passage 10 is connected to the middle position of the valve plug hole, and the upper end of the second air passage 10 is connected to multiple second burner head assemblies 8. The upper ends of the first burner head assembly 7 and the second burner head assembly 8 can support the container.
[0027] The valve plug orifice is a stepped orifice. The diameter of the inner section 401 of the valve plug orifice is smaller than that of the middle section 402. A first sealing ring 11 is installed at the inner end of the valve plug corresponding to the position of the inner section 401. The first sealing ring fits snugly against the inner wall of the inner section 401. A second sealing ring 12 is installed in the middle of the valve plug. The second sealing ring fits snugly against the inner wall of the middle section 402. When the valve plug is extended to the inner limit position, the first sealing ring is located between the inner end of the first air passage and the inner end of the second air passage, and the second sealing ring is located between the inner end of the second air passage and the outer end of the valve plug orifice. The inner end of the valve plug blocks the connecting hole 6.
[0028] An internal thread is provided at the outer section 403 of the valve plug hole, and an external thread is provided at the outer end of the valve plug. The valve plug and the valve plug hole are connected by a thread. An extension rod 13 is provided at the outer end of the valve plug, and a knob 14 is provided at the outer end of the extension rod. Through the design of the knob and the extension rod, the valve plug can be rotated more conveniently, thereby adjusting the position of the valve plug in the valve plug hole, thereby controlling the opening and closing of the connecting hole, and then controlling the opening and closing of the first air passage and the second air passage.
[0029] The base 1 includes a lower base 101 and an upper base 102. The first air passage and the second air passage are both opened inside the lower base. The upper base 102 is sleeved on the upper end of the lower base 101. The upper base is provided with multiple support arms 1021. The first flame head assembly 7 is installed on the upper end of the lower base 101. Multiple second flame head assemblies are respectively installed on the upper side of the outer end of the corresponding support arm 1021. A third air passage 15 is opened inside the support arm. The inner ends of the multiple third air passages 15 are interconnected and connected to the upper end of the second air passage.
[0030] The inner end of the valve plug is a tapered part 16, and the connecting hole is a tapered hole that matches the shape of the tapered part. When the valve plug is extended to the inner limit position, the tapered part 16 closes the tapered hole. The intake rate can be controlled by adjusting the position of the valve plug.
[0031] Operating principle: When the valve plug is inserted to its inner limit position, the connecting hole is closed, and the burner is in a non-gas-supply state. When the user drives the valve plug outward, the connecting hole is opened first. The first sealing ring still prevents gas from entering the second gas passage. At this time, the gas in the gas supply pipe passes through the valve plug hole and the first gas passage to supply the first burner assembly. The gas is ejected from the top of the first burner assembly and can be ignited by the ignition device to achieve the first flame mode. This mode can heat small containers or only the bottom center of the container. As the valve plug is continued to be driven outward, the rate at which gas enters the first gas passage will gradually increase, and the first sealing ring will enter... In the middle section, the seal on the second gas passage is released. At this time, the rate at which the gas enters the first gas passage continues to increase. Then, the gas is supplied to the second burner assembly through the second gas passage, which can then ignite the second burner assembly to achieve the second combustion mode. When switching to the second combustion mode, the rate at which the gas enters the first gas passage will not suddenly decrease significantly. The burner in the second combustion mode can heat a larger container at the bottom. Similarly, when switching from the second combustion mode to the first combustion mode, the rate at which the gas enters the first gas passage will also decrease simultaneously to prevent the flame of the first burner assembly from suddenly becoming much larger when switching from the second combustion mode to the first combustion mode.
[0032] This device allows for convenient adjustment of the gas supply path and combustion mode through the cooperation of the valve plug and valve plug hole, as well as the first and second gas passages. Combined with the cooperation of the conical part and the conical connecting hole, it can achieve different maximum air intake rates for the first and second combustion modes. That is, as the valve plug moves outward, the air intake rate increases linearly. This avoids the flame of the first burner assembly from suddenly becoming too small when switching from the first to the second combustion mode, and also avoids the flame of the first burner assembly from suddenly becoming too large when switching from the second to the first combustion mode. This solves the problem of difficult flame size control when switching combustion modes, making it safer and more reliable to use.
