Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of barbecue stove valves, in particular to an integrated barbecue stove valve. Background Art
[0002] The barbecue grill valve is a key component for controlling the flow of gas in the grill. It's primarily used to control gas flow, ignite the gas, and provide protection against leaks. During the ignition process of a conventional barbecue grill valve, a sufficient concentration of gas is pre-filled through the valve. A spark from a lighter then ignites the gas. This spark can cause the gas inside the grill to instantly explode, leading to the following issues: 1. The grill temperature rises instantly, making it difficult to accurately and stably control the temperature. 2. The instant the gas explodes, the pressure inside the grill increases instantly, pushing it outward, posing a safety hazard. Utility Model Content
[0003] The purpose of the utility model is to provide an integrated barbecue grill valve to solve the technical problems described in the background art.
[0004] The integrated barbecue grill valve includes a main body, the main body is provided with a main channel, the main channel is provided with an air inlet and an air outlet, the air inlet is provided with an adjusting switch, the main body is provided with a cache chamber, the cache chamber is arranged with a plurality of cache channels connected to the main channel, the capacity between the plurality of cache channels is arranged from small to gradually increasing, the cache channel with the largest capacity is provided with a small interface connected to the air outlet, the small interface is provided with an igniter, the remaining small-capacity cache channels are provided with a large interface connected to the air outlet, the large interface is provided with a one-way door mechanism with resistance, and the flow of the small interface is less than the flow of the air inlet.
[0005] According to the technical solution, when the integrated barbecue grill valve is working, gas enters the main channel from the air inlet, and then enters the cache chamber from the main channel. When the gas enters the cache channel with the maximum capacity, a small part of the gas is discharged from the small interface to the gas outlet, and the rest of the gas will be blocked and discharged from the small interface and stored in the cache channel. At this time, the igniter ignites the gas discharged from the small interface. Thereafter, when the cache channel is full of gas, the gas pressure in the cache channel will push the one-way door mechanism to open. At this time, the gas in the cache channel is discharged from the large interface to the gas outlet, and the flame on the small interface will ignite the gas discharged from the large interface, so that the utility model can achieve the following beneficial effects:
[0006] During ignition, a buffer channel is provided to pre-utilize a small portion of the gas to be discharged from the small interface, and the gas discharged from the small interface is ignited to keep the small interface in a state of continuous low-fire combustion, while the remaining gas is delayed and discharged from the large interface, so that the remaining gas can be ignited immediately when it is discharged from the large interface, and will not be dissipated and stored inside the barbecue grill, thus avoiding the instantaneous explosion of gas inside the barbecue grill and the resulting instantaneous increase in temperature and pressure. Therefore, the temperature can be accurately and stably controlled and safety can be improved.
[0007] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.
[0008] In some embodiments, the caliber of the large interface decreases as the capacity of the cache lane gradually increases;
[0009] According to the technical solution, when gas with a relatively large pressure and flow rate is inputted into the gas inlet, the gas outputted from the gas outlet can be gradually ignited, thereby further avoiding gas explosion.
[0010] In some embodiments, the gas outlet is a slot-shaped port, the small port faces the large port, and the igniter is located at the small port;
[0011] According to the technical solution, the flame at the small interface can more stably ignite the gas discharged from the large interface.
[0012] In some embodiments, the small interface is provided with a pressurized mesh plate; according to the technical solution, when the gas pressure and flow rate output from the small interface are too low, the flame can be effectively prevented from entering the cache channel from the small interface.
[0013] In some embodiments, the small interface and the large interface are both provided with a one-way door mechanism;
[0014] According to the technical solution, when the gas pressure and flow output from the small interface or large interface are too low, the small interface or large interface can be closed through a one-way door mechanism, thereby further preventing the flame from entering the cache channel from the small interface or large interface.
[0015] In some embodiments, the one-way door mechanism includes a rotating shaft, a limiting bar, and a magnet. The rotating shaft is mounted with a door body that can swing outward. The limiting bar is used to limit the door body from swinging inward. The magnet is used to adsorb, fix, and reset the door body.
[0016] According to the technical solution, when the cache channel is full of gas and the gas enters the cache chamber from the main channel, until the gas in the cache channel reaches the set pressure, the gas pressure in the cache channel will push the door body to open, and the gas can be discharged from the small interface or the large interface. Therefore, when the gas pressure and flow output from the small interface or the large interface are too low, the magnet attracts the door body to reset, so that the small interface or the large interface is closed, thereby effectively preventing the flame from entering the cache channel from the small interface or the large interface, so as to achieve the protection of the barbecue grill valve and the gas source.
[0017] In some embodiments, the magnetic force of the magnet decreases as the capacity of the cache track increases;
[0018] According to the technical solution, when gas with a relatively high pressure and flow rate is inputted into the gas inlet, the gas outputted from the gas outlet can be gradually ignited and the output can be gradually delayed and ignited, thereby further avoiding gas explosion.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following is an enumerated description with reference to the appended drawings.
[0025] like Figure 1 and 2 As shown, this specific embodiment provides an integrated barbecue grill valve, which includes a main body 1, the main body 1 is provided with a main channel 2, an air outlet 3 and a buffer chamber 5, the main channel 2 is provided with an air inlet 4, and the air inlet 4 is provided with an adjustment switch 41.
[0026] The cache chamber 5 is arranged with several cache lanes 51 connected to the main channel 2. The capacity of the cache lanes 51 increases gradually from small to large. The cache lane 51 with the largest capacity is equipped with a small interface 6 connected to the air outlet 3, while the remaining cache lanes 51 with smaller capacities are equipped with large interfaces 7 connected to the air outlet 3. The flow rate of the small interface 6 is less than that of the air inlet 4. The small interface 6 is equipped with a pressurized mesh plate 62, and the large interface 7 is equipped with an igniter 61. The diameter of the large interface 7 gradually decreases as the capacity of the cache lane 51 increases. The air outlet 3 is a slot-shaped opening, with the small interface 6 facing the large interface 7, and the igniter 61 is located at the small interface 6.
[0027] Both the small interface 6 and the large interface 7 are provided with a one-way door mechanism, which includes a rotating shaft 81, a limit bar 82 and a magnet 83. A door body 84 that can swing outward is installed on the rotating shaft 81. The limit bar 82 is used to limit the door body 84 from swinging inward. The magnet 83 is used to adsorb, fix and reset the door body 84. The magnetic force of the magnet 83 decreases as the capacity of the cache channel 51 increases.
[0028] The following is a working description of the integrated barbecue grill valve described in this specific embodiment.
[0029] During operation, the gas enters the main channel 2 from the air inlet 4, and then enters the cache chamber 5 from the main channel 2. When the gas enters the cache channel 51 with the maximum capacity, a small amount of gas is discharged from the small interface 6 to the air outlet 3, which will push the one-way door mechanism of the small interface 6 to open. At this time, the igniter 61 ignites the gas discharged from the small interface 6, and the small interface 6 is in a state of maintaining combustion; thereafter, the remaining gas will be blocked by the small interface 6 and discharged and stored in the cache channel 51. Thereafter, when the cache channel 51 is full of gas, the gas pressure in the cache channel 51 will push the one-way door mechanism on the large interface 7 to open. At this time, the gas in the cache channel 51 is discharged from the large interface 7 to the air outlet 3, and the flame on the small interface 6 will ignite the gas discharged from the large interface 7.
[0030] When the gas pressure and flow output from the small interface 6 or the large interface 7 are too low, that is, the gas pressure in the cache channel 51 is insufficient to push the one-way door mechanism to open, the one-way door mechanism will reset and close the small interface 6 or the large interface 7, thereby preventing the flame from entering the cache channel 51 from the small interface 6 or the large interface 7.
[0031] When the one-way door mechanism is working, when the cache channel 51 is full of gas and the gas enters the cache chamber 5 from the main channel 2, until the gas in the cache channel 51 reaches the set gas pressure, the gas pressure in the cache channel 51 will push the door body 84 to open, and the gas can be discharged from the small interface 6 or the large interface 7. Therefore, when the gas pressure and flow output from the small interface 6 or the large interface 7 are too low, the magnet 83 attracts the door body 84 to reset, so that the small interface 6 or the large interface 7 is closed, thereby effectively preventing the flame from entering the cache channel 51 from the small interface 6 or the large interface 7, so as to protect the barbecue grill valve and the gas source.
