Description

Technical Field

[0001] This utility model relates to a split-type outdoor stove valve body and a split-type outdoor stove. Background Technology

[0002] Existing portable gas stoves mostly adopt an integrated structure where the gas canister and the stove valve body are combined into one unit, with the gas canister directly installed below or on the side of the valve body, and the two are rigidly connected. While this structure is convenient for carrying and installation, it has the following shortcomings in practical use:

[0003] The gas cylinder is rigidly connected to the valve body. If the connection becomes loose during outdoor handling, collision, or tipping, it can easily cause gas leakage, posing a significant safety hazard. Improper operation or uneven ground can also cause the interface to shift, leading to leakage accidents, which are especially dangerous in outdoor environments.

[0004] Traditional split-type outdoor stoves typically have only one exhaust duct, meaning gas can only be delivered to the burner via a single path, limiting flame width and thermal efficiency. In cooking scenarios requiring greater heat or more even heating (such as grilling large items or multi-point heating), a single-path gas supply often fails to meet user needs.

[0005] Existing portable gas stoves generally only support the output of a single burner, cannot drive multiple flame zones at the same time, and do not have the ability to independently adjust the center and outer flames. They lack cooking flexibility and are not suitable for complex cooking methods (such as pan-frying or circular boiling).

[0006] Because current technology only provides one gas cylinder connection port, it can only connect to one butane gas cylinder. When butane is used at high power, the internal temperature of the cylinder drops rapidly, resulting in a decrease in gas pressure and a weaker flame, which is particularly noticeable in winter, seriously affecting cooking efficiency and user experience. Utility Model Content

[0007] The primary objective of this invention is to provide a split-type outdoor stove valve body that offers safety, multi-channel gas supply, cooking flexibility, and stability in low-temperature environments.

[0008] The second objective of this invention is to provide a split-type outdoor stove that offers safety, multi-channel gas supply, cooking flexibility, and stability in low-temperature environments.

[0009] The primary objective of this invention is achieved as follows:

[0010] A split-type outdoor stove valve body includes a valve body, an adjustment device, and an igniter. The valve body has an internal air inlet, a pressure reducing chamber, an adjustment chamber, a first exhaust chamber, and a second exhaust chamber. The pressure reducing chamber is equipped with a pressure reducing adjustment rod for reducing gas pressure. The valve body is provided with at least two interconnected gas cylinder connection ports. The inlet of the air inlet is connected to the gas cylinder connection port, the outlet of the air inlet is connected to the inlet of the pressure reducing chamber, and the outlet of the pressure reducing chamber is connected to the inlet of the adjustment chamber.

[0011] The inlet of the first exhaust duct is connected to the outlet of the regulating chamber, and the outlet of the first exhaust duct extends out of the valve body for connection to the burner head;

[0012] The inlet of the second exhaust duct is connected to the outlet of the regulating chamber, and the outlet of the second exhaust duct extends out of the valve body for connection to the furnace head;

[0013] The valve body has an installation port at the position of the adjustment chamber. The front end of the adjustment device passes through the installation port and enters the adjustment chamber. The tail end of the adjustment device protrudes from the installation port to form a control part.

[0014] The igniter is mounted on the valve body, and the push-button switch of the igniter is located near the control unit.

[0015] When the adjusting device rotates, the control unit starts or stops the igniter. At the same time, the adjusting device controls the opening degree of the adjusting chamber outlet, thereby controlling the opening degree of the first exhaust passage and the second exhaust passage.

[0016] By setting at least two interconnected gas cylinder connection ports on the valve body, the gas cylinder and the valve body are connected in a separate and flexible manner, which avoids the risk of loosening of the interface and gas leakage caused by collision or tilting when the gas cylinder and the valve body are rigidly connected, thus greatly improving the safety of use.

[0017] The present invention has two exhaust channels, a first and a second, inside the valve body, which can simultaneously supply gas to two burners or different areas of the center and periphery of the burner plate. The two fires can be turned on and off synchronously through the same rotary adjustment device, and the flame width and heating area are significantly improved, meeting diverse needs such as large-volume cooking and ring heating.

[0018] The dual-cylinder parallel gas supply method disperses the low-temperature cooling effect of butane gas in a single cylinder, slowing down the rate of temperature drop in the gas tank. This allows it to maintain stable gas pressure and firepower output even in low-temperature environments, making it particularly suitable for outdoor camping, winter picnics, and other similar scenarios.

[0019] By integrating the igniter and rotary adjustment device into the same control unit, users can simply rotate the control unit to complete ignition, on / off and firepower adjustment without the need for additional pressing or switching parts. The operation is intuitive and convenient, greatly improving the user experience.

[0020] The primary objective of this utility model can also be achieved by the following technical measures:

[0021] Furthermore, it also includes a plug, which is detachably installed at the gas cylinder connection port to seal the gas cylinder connection port.

[0022] The unused gas cylinder connection port can be sealed by a removable plug to prevent gas from leaking through the idle interface;

[0023] In single-cylinder gas supply mode, the plug can be flexibly installed or removed, which ensures the system's sealing performance without requiring additional modifications to the valve body structure, thus improving the product's versatility and safety.

[0024] Furthermore, the inner wall of the gas cylinder connection port is provided with an internal thread, the plug is provided with an insertion part, the outer wall of the insertion part is provided with an external thread, the insertion part is inserted into the gas cylinder connection port, the external thread and the internal thread engage, and the insertion part of the plug seals the gas cylinder connection port.

[0025] After the plug is inserted, the threads engage, ensuring reliable mechanical locking and airtight sealing between the plug and the valve body;

[0026] The threaded structure allows users to quickly tighten or loosen the seal, making it intuitive to operate, stable and durable. Compared to snap-on or rubber plug seals, it is more resistant to high pressure and vibration, further reducing the risk of leakage.

[0027] Furthermore, the angle between the gas cylinder connection port and the gas cylinder connection port is 90°, and an air outlet is opened at the angle to connect to the gas cylinder connection port, and the inlet of the air inlet is connected to the air outlet.

[0028] The two gas cylinder connection ports are designed to be perpendicular to each other at 90°, and an air outlet is opened at the corner, which can efficiently connect the air inlet to the two connection ports.

[0029] The vertical arrangement saves space in the valve body, making the overall structure more compact. It also facilitates the uniform distribution of fluid after pressure reduction, ensuring consistent air pressure in both exhaust ducts, resulting in stable firepower and more uniform heating.

[0030] Furthermore, it also includes a first gas guide pipe for connecting to the burner head and a second gas guide pipe for connecting to the burner head, wherein the first gas guide pipe is connected to a first exhaust channel, and the second gas guide pipe is connected to a second exhaust channel.

[0031] The exhaust passage inside the valve body is directly connected to the furnace head through the first and second gas guide pipes, simplifying the layout of external pipelines.

[0032] Furthermore, it also includes a gas pipeline for connecting the gas cylinder, the gas pipeline being connected to the gas cylinder connection port.

[0033] An independent gas pipeline interface is added, allowing external gas cylinders to be directly connected to the valve body via a standardized hose. The hose connection method is compatible with various commercially available butane tanks, making installation faster. At the same time, the hose has a certain degree of flexibility, which can reduce mechanical stress caused by angle limitations, improving ease of use and safety.

[0034] Furthermore, the valve body has a first exhaust passage on the left side near the regulating chamber, and a second exhaust passage on the right side near the regulating chamber.

[0035] The first and second exhaust channels are respectively opened on the left and right sides of the valve body to achieve airflow separation and left-right symmetrical arrangement;

[0036] The split layout on the left and right sides not only makes it convenient for users to install multiple burners in different directions, but also improves the structural balance and overall aesthetics of the valve body, and helps to distribute heat evenly.

[0037] Furthermore, the angle between the mounting port and the gas cylinder connection port is 90°. The adjustment device includes a valve core and a knob. One end of the valve core is connected to the knob, and the other end of the valve core passes through the mounting port (enters into the adjustment chamber) so that the angle between the knob and the gas cylinder connection port is 90°. The rotation of the valve core controls the opening degree of the outlet of the adjustment chamber, thereby controlling the opening degree of the first exhaust passage and the second exhaust passage.

[0038] The knob is equipped with a paddle; when the knob is rotated, the paddle touches or moves away from the igniter.

[0039] The installation port is at a 90° angle to the gas cylinder connection port, so that the rotary adjustment device (valve core + knob) and the air intake pipeline do not interfere with each other, improving the operating space and ergonomic experience;

[0040] The valve core and knob are integrated into one design, which simultaneously adjusts the opening of the two exhaust channels when rotated, and achieves "one-turn ignition" by touching the igniter with a paddle, making the operation intuitive and efficient;

[0041] The paddle mechanism on the knob serves as both a travel limit switch and a trigger switch, ensuring ignition reliability while preventing accidental activation, thus enhancing user experience and safety.

[0042] Furthermore, it also includes a resilient valve core for opening or closing the gas cylinder connection port, the resilient valve core being movably disposed within the gas cylinder connection port, the resilient valve core moving to open or close the gas cylinder connection port.

[0043] Each gas cylinder connection port is equipped with a flexible valve core, which can automatically open when the gas pipeline is inserted and automatically close when it is pulled out, thus achieving self-sealing of the interface;

[0044] This automatic valve core structure eliminates the need for additional manual plugs or tools, allowing for rapid gas shut-off after hose disconnection. This significantly reduces the risk of gas leaks due to operational errors and enhances the product's safety protection capabilities.

[0045] The second objective of this utility model is achieved as follows:

[0046] A split-type outdoor stove includes a shell and a burner head. The front end face of the shell has a first notch, and the right side wall of the shell has a second notch to facilitate the passage of a gas pipe. The burner head is located on the top of the shell. The valve body of the split-type outdoor stove is located in the inner cavity of the shell. The valve core passes through the first notch and connects to the knob. The burner head includes an outer ring flame gas pipe and an inner ring flame gas pipe. The first exhaust duct connects to the outer ring flame gas pipe, and the second exhaust duct connects to the inner ring flame gas pipe.

[0047] The burner features a dual-ring structure with inner and outer flames, each supplied with gas independently by a second and first exhaust duct, allowing for precise control of the central burner and the outer flame zones. Users can choose between single-ring or dual-ring cooking, or adjust the knob to obtain multiple levels of heat from low to high, meeting various cooking needs from stewing and frying to stir-frying, further improving cooking flexibility and efficiency.

[0048] The separate outdoor stove valve body, valve core, and knob are integrated into the inner cavity of the outer shell, and corresponding notches are opened at the front end and side wall of the outer shell. This not only ensures the space arrangement of the knob and gas pipe, but also makes the overall appearance simple and beautiful. At the same time, the connection path between the valve body and the stove head is short and the protection is good, taking into account the product's portability, durability and ease of maintenance.

[0049] The beneficial effects of this utility model are as follows:

[0050] This invention, through at least two interconnected gas cylinder connection ports and a dual exhaust channel design, enables parallel gas supply from two cylinders. After pressure reduction and regulation, the gas is delivered to the first and second exhaust channels respectively, significantly mitigating the low-temperature cooling effect of a single cylinder of butane at high power output, and ensuring continuous and stable firepower in winter and under high load.

[0051] This invention uses a single rotary adjustment device to control the opening of the adjustment chamber outlet, which can simultaneously or separately adjust the size of the outer ring and inner ring flames (first exhaust channel and second exhaust channel), thereby achieving ring-shaped firepower zone control and meeting various cooking needs such as frying, stir-frying, boiling, and braising.

[0052] This invention cleverly combines the igniter push-button switch with the adjustment knob. Users can complete ignition, on / off and firepower adjustment simply by rotating the control unit, without the need for additional pressing or switching. The operation is intuitive and efficient, improving the user experience and safety.

[0053] This invention employs a dual-ring structure at the burner head, consisting of an inner ring flame and an outer ring flame, with independent gas supply from the second and first exhaust ducts respectively. This allows for precise zoned control of the central burner and the outer flame. Users can choose between single-ring or dual-ring cooking, or adjust the knob to obtain multiple levels of heat from low to high, meeting various cooking needs from stewing and frying to stir-frying, further improving cooking flexibility and efficiency.

[0054] This invention uses a removable plug to seal unused gas cylinder connections, preventing gas leakage through idle interfaces. In single-cylinder supply mode, the plug can be flexibly installed or removed, ensuring system sealing without requiring additional modifications to the valve body structure, thus improving the product's versatility and safety.

[0055] This invention features a flexible valve core installed in each gas cylinder connection port. This valve core automatically opens when the gas pipeline is inserted and automatically closes when it is removed, achieving self-sealing of the interface. This automatic valve core structure eliminates the need for additional manual plugs or tools, allowing for rapid gas cut-off after hose disassembly. This significantly reduces the risk of gas leakage due to operational errors and enhances the product's safety protection capabilities. Attached Figure Description
