Description

Technical Field

[0001] This utility model relates to an adapter for changing the gas inlet direction of a valve body, a cassette valve body, and a cassette stove. Background Technology

[0002] A portable gas stove is widely used for outdoor activities, picnics, and home emergencies. A traditional gas stove typically includes a valve body, regulating device, igniter, and a gas cylinder connector. Existing gas stove designs suffer from several significant drawbacks:

[0003] Large size: In traditional designs, the gas cylinder connector and the adjustment knob are on the same straight line. This structure increases the overall length and size of the portable gas stove. This design is not conducive to the portability and storage of the product, especially in situations with limited space, increasing the inconvenience of use.

[0004] Space occupation: The knob is usually located on the valve body, and its position requires a certain amount of space, which further increases the size of the cassette stove, affecting the compactness of the stove and the rationality of the overall design.

[0005] Large packaging volume: Due to the aforementioned design, portable gas stoves are relatively large, thus increasing packaging volume. This not only increases storage space requirements but also raises transportation costs, negatively impacting the product's market competitiveness.

[0006] High transportation costs: The increased packaging volume directly leads to higher transportation costs. Whether in warehousing or logistics, the larger portable gas stoves occupy more space, thus increasing the transportation cost per unit and affecting the product's cost-effectiveness.

[0007] The knob cannot be located on the top of the portable gas stove: Since the height of a typical portable gas stove is less than the height of the gas cylinder, and the knobs for the cylinder connector and adjustment device are on the same straight line, the knob cannot be placed on the top of the stove. If the knob were located on the top, the overall design of the portable gas stove would need to accommodate the height of the gas cylinder, further resulting in an excessively tall stove. This makes the overall structure of the portable gas stove impractical, inconvenient to carry and store. Utility Model Content

[0008] The primary objective of this invention is to provide an adapter for changing the direction of the gas inlet of a valve body.

[0009] The second objective of this invention is to provide a cassette valve body that changes the direction of the gas inlet of the valve body.

[0010] The third objective of this invention is to provide a portable gas stove that effectively reduces volume, improves portability, and lowers transportation costs.

[0011] The fourth objective of this invention is to provide a portable gas stove that effectively reduces volume, improves portability, and lowers transportation costs.

[0012] The primary objective of this invention is achieved as follows:

[0013] An adapter for changing the direction of the gas inlet of a valve body includes an adapter and a gas cylinder connector. The head of the adapter has an exhaust port, and the tail of the adapter has an intake port. The included angle between the head and the tail is greater than 0° and less than 180°.

[0014] The head of the adapter is used to connect to the cassette valve body, and the exhaust port is used to connect to the gas inlet of the cassette valve body.

[0015] The gas cylinder connector has a gas cylinder connection port and is detachably fixed to the tail of the adapter. The gas cylinder connection port is connected to the air inlet port.

[0016] By designing an adapter so that the gas inlet and gas cylinder connection are not on the same line, the bulky size of traditional portable gas stoves (PVS) is avoided, as well as the inability to place the knob on the top of the stove. This allows for flexible knob placement on the surface or side of the stove, effectively reducing its height and size. Using this adapter in the PPS valve body results in a more compact design, making it more suitable for portable storage.

[0017] Due to the angled design of the adapter, the valve body of the cartridge oven using this adapter is applied to the cartridge oven, resulting in a more compact overall structure. This not only reduces the overall size but also effectively lowers the packaging volume. This improves storage efficiency while reducing transportation space requirements, thus helping to reduce transportation costs.

[0018] Thanks to optimized design, the size and transportation costs of portable gas stoves have been effectively controlled, making the product more economical and more competitive in the market.

[0019] The primary objective of this utility model can also be achieved by the following technical measures:

[0020] Furthermore, the adapter is a 90-degree adapter.

[0021] The adapter features a 90-degree design, effectively avoiding the problem of excessively large portable gas stoves caused by traditional designs by changing the angle between the gas cylinder connector and the gas inlet. The 90-degree adapter allows for a more compact arrangement of the gas cylinder connector and gas inlet, thereby reducing the overall size of the portable gas stove, making it easier to store and carry, and particularly suitable for outdoor activities, picnics, and other similar scenarios.

[0022] In traditional designs, the knobs of the gas cylinder connector and the regulating device are on the same straight line, making it impossible to place the knobs on the top of the portable gas stove, which affects ease of use. The 90-degree adapter design allows the knobs to be flexibly placed on the top or side of the portable gas stove, thus avoiding the problems of the traditional design and enhancing the convenience and comfort of operation.

[0023] The 90-degree adapter brings greater flexibility to the design of portable gas stoves. The relative positions of the knob and gas cylinder connector are no longer limited to the traditional linear layout. Designers can adjust the positions of the knob and gas cylinder connector according to actual needs, achieving a more flexible and user-friendly design that meets the usage habits and convenience needs of different users.

[0024] The reduced size of portable gas stoves allows for effective compression of their packaging volume, thereby lowering storage space and transportation costs. This not only improves production efficiency but also enhances the competitiveness of portable gas stoves in the market, making them more economical.

[0025] The second objective of this utility model is achieved as follows:

[0026] A portable gas stove includes a housing and bolts. The housing has a gas inlet. The head of the adapter is detachably connected to a valve body. The housing has a retaining ring around the gas inlet. The side wall of the retaining ring has a first retaining opening spaced apart. The housing has a first bolt seat corresponding to the first retaining opening.

[0027] The adapter has a first locking piece spaced apart at its head.

The side wall of the locking seat is spaced apart with a second locking opening, and the tail of the adapter is provided with a second bolt seat corresponding to the position of the second locking opening.

[0035] The gas cylinder connector is provided with a plug that connects to the gas cylinder connection port. The plug is provided with second locking pieces at intervals. The plug is inserted into the locking piece, and the plug and the locking piece fit tightly together. The second locking piece is inserted into the corresponding second locking hole. The bolt passes through the second locking piece and locks the corresponding second bolt seat, thereby realizing the connection between the gas cylinder connector and the adapter.

[0036] By incorporating a locking seat and a second locking port at the tail of the adapter, and a second locking piece at the gas cylinder connector plug, all secured with bolts, a tight connection between the gas cylinder connector and the adapter is ensured. This design enhances the stability of the connection points, preventing loosening due to vibration or improper operation during use, thereby improving the safety and reliability of the portable gas stove.

[0037] The tight fit between the connector and the retaining seat, and the insertion of the retaining clip into the corresponding retaining slot, ensures accurate connection and avoids gas leakage caused by loose fit. Good fit precision improves sealing performance, effectively prevents gas leakage, and enhances product safety.

[0038] The bolt-locking method ensures a tight fit at the connection points, effectively preventing the risk of gas leakage. At the same time, the tight fit between the plug and the mounting bracket further enhances the seal between the gas cylinder connector and the adapter, ensuring the safe use of the portable gas stove.

[0039] This design, through precise fitting and bolt-locking structure, ensures a stable connection between the gas cylinder connector and the adapter, enabling it to withstand high temperatures and prolonged use, thus extending the service life of the portable gas stove.

[0040] The detachable design allows users to easily and quickly maintain or replace the gas cylinder connector. This structure not only improves the maintainability of the portable gas stove but also makes daily use more flexible, reducing maintenance costs and time.

[0041] This design, through the ingenious combination of the mounting base and the mounting plate, simplifies the assembly process, reduces the need for traditional welding or complex connection methods, and helps to improve production efficiency and reduce manufacturing costs.

[0042] The third objective of this utility model is achieved as follows:

[0043] A 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 for easy access to a gas cylinder. The burner head is located on the top of the shell. A cartridge stove valve body is located inside the shell. The valve core of the cartridge stove valve body passes through the first notch and is connected to a knob. The gas discharge port of the cartridge stove valve body is connected to the burner head.

[0044] By creating a first and a second notch on the front and right side walls of the outer casing, the overall structural design of the portable gas stove has been optimized, reducing its size. The first notch provides space for the connection between the valve core and the knob, while the second notch facilitates the removal and placement of the gas cylinder. This design makes the stove more compact and suitable for portable use, especially advantageous when space-saving storage is required.

[0045] Thanks to optimized design, the overall size of the portable gas stove has been reduced, resulting in a decrease in packaging volume and storage space requirements. This not only helps lower transportation costs but also allows the product to gain a more advantageous position in the market and enhance its competitiveness.

[0046] Through innovative design, the operation of portable gas stoves and the replacement of gas cylinders have become simpler, allowing users to experience greater convenience and comfort in daily use, especially suitable for outdoor activities and outdoor fire-making scenarios.

[0047] The compact design gives the product a greater advantage in the market, especially in consumer scenarios where portability and storage space are in high demand. It can meet the needs of more consumers and enhance the product's market appeal and competitiveness.

[0048] The fourth objective of this utility model is achieved as follows:

A cassette valve body is located inside the shell. The valve core of the cassette valve body passes through the first notch and is connected to a knob. The gas discharge port of the cassette valve body is connected to the burner head.

[0050] By placing the knob on top of the portable gas stove and connecting it to the valve core via a first notch, users can easily adjust the gas flow by rotating it. The knob design makes operation more intuitive and unrestricted by space, enhancing the user experience, especially in outdoor or confined spaces.

[0051] The second notch design facilitates the placement and removal of gas cylinders, allowing users to quickly and easily replace them. Users can operate the system easily without disassembling or moving complex parts, greatly improving the efficiency and convenience of gas cylinder replacement.

[0052] Due to the reduced overall size, portable gas stoves occupy less space during packaging, effectively lowering storage and transportation costs. This reduces logistics costs and improves storage efficiency, making them particularly suitable for mass production and market sales.

[0053] Its compact size and easy-to-use design give this portable gas stove a competitive edge in the market. Its portability, ease of operation, and quick gas cylinder replacement features will attract more consumers, especially in outdoor and camping settings.

[0054] In summary, this design, through optimizing the valve body layout, knob position, and notch design, not only effectively reduces the size of the portable gas stove and improves its portability, but also enhances operational convenience and safety, making the portable gas stove more advantageous in the market.

[0055] The beneficial effects of this utility model are as follows:
