Description

Technical Field

[0001] The utility model relates to a cartridge furnace valve body and a cartridge furnace using the cartridge furnace valve body. Background Art

[0002] A cassette stove is a portable stove widely used in outdoor activities, picnics and household emergency use. The traditional cassette stove structure usually includes a valve body, an adjustment device, an igniter and a gas cylinder connector for connecting a gas cylinder. The valve body design of the cassette stove in the prior art makes the gas cylinder connector and the knob of the adjustment device on the same straight line. This design has some significant disadvantages, as follows:

[0003] Large volume: Since the gas cylinder connector and the knob are in the same straight line, the overall length of the structure increases, resulting in a larger overall volume of the cassette stove. This design is not conducive to portability and storage, especially when you need to save space.

[0004] Large space occupation: The position of the knob on the valve body usually requires a large space, which further increases the volume of the cassette furnace, making the design and use less compact.

[0005] Large packaging volume: Due to the above design, the volume of the cartridge furnace is large, and the packaging volume increases accordingly, which not only increases the storage space demand, but also increases the transportation cost, which is not conducive to economy and market competitiveness.

[0006] High transportation cost: Large packaging volume directly leads to increased transportation costs. Whether it is warehousing or logistics transportation, large-volume cassette furnaces will take up more space, thereby increasing the transportation cost of a single product. Utility Model Content

[0007] The first purpose of the utility model is to provide a cartridge furnace valve body which optimizes the relative position of the gas cylinder connector and the regulating device, makes the overall structure of the cartridge furnace more compact, and effectively reduces the product volume, packaging volume and transportation cost.

[0008] The second purpose of the utility model is to provide a cassette stove that optimizes the relative position of the gas cylinder connector and the adjustment device, making the overall structure of the cassette stove more compact, effectively reducing the product volume, packaging volume, transportation cost and enhancing the portability of the product.

[0009] The first purpose of the utility model is achieved in this way:

[0010] A cartridge stove valve body, comprising a valve body, a regulating device, an igniter and a gas cylinder connector for connecting a gas cylinder, wherein the valve body is provided with an air inlet, a regulating chamber and an exhaust passage, wherein the inlet of the air inlet is connected to the gas cylinder connector, the outlet of the air inlet is connected to the inlet of the regulating chamber, the outlet of the regulating chamber is connected to the inlet of the exhaust passage, and the outlet of the exhaust passage extends out of the valve body for connecting to a stove head;

[0011] The valve body is provided with a mounting opening at a position corresponding to the regulating cavity, and the angle between the mounting opening and the gas cylinder connector is 90°;

[0012] The igniter is arranged on the valve body, and the push switch of the igniter is close to the installation opening;

[0013] The regulating device comprises 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 into the regulating cavity, so that the angle between the knob and the gas cylinder connector is 90°, and the valve core rotates to control the opening degree of the outlet of the regulating cavity, thereby controlling the opening degree of the exhaust passage;

[0014] The knob is provided with a paddle, and when the knob is rotated, the paddle touches or moves away from the igniter.

[0015] By designing the angle between the installation port and the gas cylinder connector to be 90°, the layout of the components in the valve body is optimized, making the structure of the entire cartridge furnace more compact. This design can reduce the overall volume of the cartridge furnace, making it easier to carry and store.

[0016] The positions of the knob and the gas cylinder connector are staggered to avoid space waste caused by the two being in the same straight line, making the space utilization rate in the valve body higher and further reducing the size of the equipment.

[0017] The push switch of the igniter is arranged near the installation port, so that the user can adjust the gas flow and perform the ignition operation at the same time, thereby improving the convenience and safety of use.

[0018] The valve core in the regulating device controls the outlet opening of the regulating chamber through the knob, thereby accurately controlling the gas flow. This design allows users to adjust the fire power more accurately to meet different cooking needs.

[0019] Due to the more compact and efficient structural design, the packaging volume is reduced, thereby reducing storage and transportation costs and improving the economy and market competitiveness of the product.

[0020] The first purpose of the utility model can also be solved by the following technical measures:

[0021] Furthermore, it also includes an air guide pipe for connecting the burner head, and the air guide pipe is communicated with the exhaust duct.

[0022] The air duct provides a reliable gas transmission path, reduces the risk of gas leakage during transmission, and improves the safety and sealing of the equipment.

[0023] The air guide pipe makes the connection between the valve body and the burner head easier, making it easier for users to disassemble and install the burner head during maintenance and replacement, thus improving the maintainability and ease of use of the equipment.

[0024] The design of the air guide tube can extend the heat conduction path between the burner and the valve body, reduce the heat directly transferred to the valve body, protect the valve body and internal components from high temperature damage, and extend the service life of the equipment.

[0025] Furthermore, it also includes a protection device, which includes a push rod, a spring, a torsion spring and a rotating sheet. The valve body is provided with a push rod accommodating cavity, and the rod body of the push rod is provided with a retaining ring. The push rod is placed in the push rod accommodating cavity, and the head of the push rod passes through the push rod accommodating cavity and extends outward, and the tail end of the push rod passes through the push rod accommodating cavity and extends toward the gas cylinder connector. The spring is placed in the push rod accommodating cavity, one end of the spring abuts against the inner wall of the push rod accommodating cavity, and the other end of the spring abuts against the retaining ring, and the spring constitutes a reset mechanism of the push rod;

[0026] A contact portion is provided at one end of the rotating piece, and a blocking portion is provided at the other end of the rotating piece. The rotating piece is arranged on the valve body in a rotating manner, and the contact portion abuts against the paddle, and the paddle supports the rotating piece upward;

[0027] The torsion spring is arranged on the valve body, the legs of the torsion spring are connected to the knob plate, and the torsion force of the torsion spring pushes the rotating plate to generate a clockwise rotation trend.

[0028] The design of the protection device ensures that the ejector rod cannot be extended or retracted when the ignition is on, thereby preventing the user from accidentally replacing the gas cylinder during use and increasing safety.

[0029] When the knob is turned for ignition, the blocking portion of the rotating piece is located in front of the head of the ejector rod, ensuring that the ejector rod cannot be extended or retracted in the ignition state, thereby preventing users from accidentally replacing the gas cylinder during use and increasing safety.

[0030] When the knob is rotated clockwise to turn off the flame, the blocking part of the rotating piece is away from the head of the ejector rod, so that the ejector rod can be freely extended and retracted, which is convenient for users to replace the gas cylinder after turning off the flame, thereby improving the convenience of operation.

[0031] The ejector pin is reset by a spring, ensuring that it automatically returns to its original position after the gas cylinder is replaced, without the need for manual reset by the user, making operation easier.

[0032] The linkage design of the paddle and the rotary plate drives the paddle through the rotation of the knob, and then controls the rotation of the rotary plate, realizing the linkage operation of ignition, shutdown and gas cylinder replacement, and optimizing the user experience.

[0033] The setting of the torsion spring ensures that the rotating plate can maintain a clockwise rotation trend in the absence of external force, ensuring that in the ignition state, the blocking portion of the rotating plate is located in front of the head of the push rod, thereby ensuring that the push rod cannot be extended or retracted in the ignition state, preventing users from accidentally replacing the gas cylinder during use, thereby increasing safety of use.

[0034] The extension and retraction of the ejector rod is controlled by the blocking part, which effectively prevents the gas cylinder from accidentally loosening or falling off in the ignition state, prevents gas leakage, and enhances the safety of the equipment.

[0037] The second notch design on the right side wall of the shell is specially used to facilitate the removal and placement of gas cylinders. Users can easily replace gas cylinders without removing the shell or other parts, making the operation simpler and faster.

[0038] The valve core passes through the first notch to connect the knob, so that the user can easily adjust the firepower and perform ignition operations. The position of the first notch is reasonably designed, which is convenient for users to operate from the front and improves the convenience of use.

[0039] The valve body of the cartridge furnace is arranged in the inner cavity of the shell. Through reasonable layout and design, the structure of the entire cartridge furnace is made more compact, the occupied space is reduced, and it is convenient for storage and carrying.

[0040] The design of the outer shell not only protects the internal valve body and gas cylinder, but also prevents damage to the equipment from the external environment. At the same time, it avoids direct contact between the user and the gas cylinder and the valve body, thereby improving the overall safety of use.

[0041] With its reduced size, the cassette stove is lighter, easier to carry and store, and is particularly suitable for users who need to move frequently or have limited storage space, such as for outdoor activities such as camping and picnics.

[0042] The reduction in volume directly reduces the packaging volume of the product and reduces the space occupied during transportation, thereby reducing logistics costs and storage costs and improving economic benefits.

[0043] The smaller size and more compact structure make the overall appearance of the cassette stove more beautiful and elegant, improving the product's visual effect and market competitiveness.

[0044] The beneficial effects of the utility model are as follows:

[0045] The utility model can replace the gas cylinder when the flame is turned off and cannot replace the gas cylinder during operation. Through this design and operation steps, the safe operation of the cassette furnace in different states is ensured, the safety risks caused by misoperation are avoided, and the safety and reliability during use are improved.

[0046] The utility model optimizes the layout of the components in the valve body by designing the angle between the installation port and the gas cylinder connector to be 90 degrees, making the structure of the entire cartridge furnace more compact. This design can reduce the overall volume of the cartridge furnace, making it convenient to carry and store, and staggers the positions of the knob and the gas cylinder connector to avoid space waste caused by the two being in the same straight line, making the space utilization rate in the valve body higher and further reducing the volume of the device.

[0047] The utility model makes the structure of the whole cartridge stove more compact through reasonable layout and design, reduces the occupied space, and is convenient for storage and carrying. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] Steps and principles for replacing gas cylinders when the cassette furnace is turned off

[0072] step:

[0073] Turn off the gas valve: First, turn the knob 6 of the gas stove to the off position to ensure that the gas supply is completely stopped.

[0074] Allow to cool: Allow the stove and burner to cool completely to prevent burns or other safety hazards.

[0075] Release residual gas: Confirm that there is no residual gas pressure in the valve body 1. If there is, gently press the ignition switch to release the residual gas.

[0076] Removing the old gas cylinder: Open the second notch 92 on the right side wall of the housing 9 and remove the old gas cylinder from the gas cylinder connector 4 .

[0077] Install a new gas cylinder: Align the new gas cylinder with the interface of the gas cylinder connector 4, gently rotate and push the gas cylinder to ensure that the gas cylinder is firmly connected.

[0078] Check the sealing: Check the connection between the new gas cylinder and the gas cylinder connector 4 to ensure that there is no gas leakage.

[0079] Re-ignition: Follow normal ignition operation, turn knob 6 and press the ignition switch to re-ignite the stove.

[0080] principle:

[0081] By closing the gas valve and waiting for cooling, ensure that the gas supply is completely stopped and the cassette furnace is safe, and then safely remove the old gas cylinder and install the new gas cylinder. On the premise of ensuring good sealing, gas leakage and potential safety hazards are avoided.

[0082] Turn off the engine and replace the gas cylinder:

[0083] When the knob 6 rotates clockwise to perform the flameout operation, the paddle 61 rotates clockwise along with the knob 6. The torsion force of the torsion spring 83 is overcome, and the paddle 61 pushes the rotating piece 84 to rotate counterclockwise, so that the blocking portion 842 of the rotating piece 84 is away from the head of the push rod 81.

[0084] At this time, the push rod 81 can be freely extended and retracted, and the user can easily remove the old gas cylinder and install a new gas cylinder through the second notch 92.

[0085] After installing a new gas cylinder, check the seal to ensure there are no gas leaks.

[0086] The steps and principles of the inability to replace the gas cylinder during the operation of the cassette furnace

[0087] step:

[0088] Operation in ignition state: When the gas stove is in operation, turn knob 6 counterclockwise to the ignition position.

[0089] The linkage protection device 8 is activated: the counterclockwise rotation of the knob 6 moves the paddle 61 away from the contact portion 841 , the torsion spring 83 drives the rotating piece 84 to rotate clockwise, and the blocking portion 842 is located in front of the head of the push rod 81 .

[0090] Locking the gas cylinder connector 4: The blocking portion 842 of the rotating piece 84 blocks the push rod 81, making it unable to extend or retract, and the gas cylinder connector 4 is in a locked state.

[0091] Preventing the gas cylinder from being removed: Since the push rod 81 is blocked, the user cannot remove the gas cylinder for replacement.

[0092] principle:

[0093] The activation of the protection device 8 by the rotation linkage of the knob 6 ensures that the top rod 81 is blocked by the blocking portion 842 of the rotating piece 84 in the ignition and working state, preventing the user from removing the gas cylinder by mistake. This design increases safety, prevents the gas cylinder replacement operation in the working state, and avoids gas leakage and potential dangers.

[0094] The gas cylinder cannot be replaced during work:

[0095] When the knob 6 rotates counterclockwise to the ignition position, the paddle 61 rotates counterclockwise with the knob 6 and moves away from the contact portion 841. The torsion force of the torsion spring 83 pushes the rotating piece 84 to rotate clockwise, so that the blocking portion 842 is located in front of the head of the top rod 81.

[0096] The push rod 81 cannot be extended or retracted, and the gas cylinder connector 4 is in a locked state, preventing the user from removing the gas cylinder.

[0097] This design ensures that the gas cylinder cannot be replaced during the operation of the cassette furnace, avoiding possible gas leakage and safety hazards.

[0098] Through this design and operating steps, the safe operation of the cassette furnace in different states is ensured, the safety risks caused by misoperation are avoided, and the safety and reliability during use are improved.

[0099] Since the angle between the knob 6 and the gas cylinder connector 4 is 90°, the above-mentioned card-type stove valve can be installed on a table, with the knob located on the table top, the gas cylinder located at the bottom of the table and plugged into the gas cylinder connector 4, and the gas cylinder is placed horizontally and does not occupy the bottom space of the table.
