Technical Field
[0001] This utility model relates to the field of gas equipment technology, and in particular to a safe portable gas stove. Background Technology
[0002] Existing portable gas stoves, such as the one described in Chinese Utility Model Patent CN208011790U (title: A Slim Portable Stove, authorized on October 26, 2018), include a stove body and a valve. A gas cylinder mounting portion is located on one side of the stove body, with a cavity for mounting the gas cylinder. The valve is installed within this cavity. A burner assembly is mounted inside the stove body and fixedly connected to the base plate of the stove body. A top cover is attached to the stove body, with a through hole for the burner assembly to pass through. Multiple cookware supports evenly distributed around the burner assembly are connected to the top cover. In this utility model, the burner assembly adopts a recessed mounting structure, reducing the overall height of the portable stove to as low as 84mm. This lower height improves stability and ease of use when using cookware such as woks. The reduced overall size of the portable stove also makes it more convenient to carry, bringing convenience to users.
[0003] However, the above-mentioned portable gas stove still has the following shortcomings: (1) Generally speaking, the instruction manual of portable gas stove will specify the size of the cookware it can be used to ensure the safe use of portable gas stove. However, since the stove body and the top cover are not equipped with corresponding limiting structures, users can also place larger cookware on the portable gas stove. At this time, part of the cookware is located above and close to the gas cylinder installation part. When working, the heat of the cookware is easily transferred to the gas cylinder surface of the gas cylinder installation part, which leads to the gas cylinder temperature rising and the risk of explosion. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a portable gas stove that can limit the use of large pots on the gas stove to ensure safe use.
[0005] The purpose of this utility model is achieved as follows:
[0006] A safe portable gas stove includes a stove body and a stove frame. The stove body has an internal partition plate that divides the interior into a receiving cavity and a gas cylinder mounting cavity. A burner head assembly is mounted on the receiving cavity. The stove frame is fixed to the upper opening of the receiving cavity. A rotatable mounting cover is provided on the gas cylinder mounting cavity. The stove is characterized by further including an actuating element, a pushing element, and a resilient element. The actuating element is rotatably mounted on one side of the partition plate and located within the receiving cavity. The pushing element is movable on the partition plate, with its two ends being a gas cylinder pushing end and a gas cylinder mounting end, respectively. The cylinder limiting end and the cylinder pushing end are both located on the cylinder mounting cavity. One end of the elastic element is connected to the other side of the partition plate located on the cylinder mounting cavity, and the other end of the elastic element is connected to the cylinder pushing end. The actuating element is provided with a limiting guide rail and a limiting part is provided at one end of the limiting guide rail. The pushing element is provided with a blocking part and the blocking part extends into the limiting guide rail. When the blocking part is engaged with the limiting part of the limiting guide rail, the elastic element is in a stretched state. One end of the actuating element passes upward through the through-hole of the furnace frame and the through-hole is close to the partition plate.
[0007] This portable gas stove uses a safe design. When a user places a large pot on the stove rack, the pot will press down on one end of the actuator, causing the actuator to rotate. This, in turn, pushes the blocking part on the actuator to disengage from the limiting part of the guide rail. Simultaneously, under the elastic restoring force of the elastic element, the actuator, along with the gas cylinder pushing end and the gas cylinder limiting end, moves together. This allows the gas cylinder pushing end to move the gas cylinder installed in the gas cylinder mounting cavity, preventing the gas cylinder from continuing to supply gas to the burner assembly, thus cutting off the operation of the portable gas stove. This effectively restricts the use of large pots on the portable gas stove, ensuring its safe use.
[0008] The objective of this utility model can also be achieved by the following technical measures:
[0009] Specifically, the opening cross-section of the gas cylinder mounting cavity and the cross-section of the mounting cover are both inverted L-shaped. The mounting cover includes a top wall and a side wall, with the side wall connected to one side of the top wall. The other side of the top wall is rotatably connected to the opening of the gas cylinder mounting cavity. The inverted L-shaped opening of the gas cylinder mounting cavity facilitates the installation of the gas cylinder by the user, while the mounting cover can also effectively seal the opening of the gas cylinder mounting cavity. Furthermore, the rotatable connection between the mounting cover and the gas cylinder mounting cavity is located on one side of the top wall. Therefore, when installing the gas cylinder, the user needs to push the mounting cover to rotate with one hand and install the gas cylinder with the other hand. After installation, the user only needs to release the mounting cover, and the mounting cover can naturally rotate under its own weight to close onto the gas cylinder mounting cavity. This allows the mounting cover to effectively perform its heat insulation function and prevent the gas cylinder surface temperature from becoming too high, thus avoiding the risk of explosion.
[0010] Specifically, the top of the partition plate extends upward to form a bearing seat with a fixed shaft, and a shaft hole is opened on the other side of the top wall corresponding to the fixed shaft position, into which the fixed shaft is inserted; this rotating connection method has a simple structure and is relatively convenient to operate.
[0011] Specifically, one end of the pusher is provided with a gas cylinder limiting wall, and an elastic sheet is connected to the gas cylinder limiting wall. There is an elastic movement gap between the elastic sheet and the gas cylinder limiting wall. The gas cylinder limiting wall and the elastic sheet on it constitute the gas cylinder limiting end. The elastic sheet can abut against the non-outlet end of the gas cylinder, so that the gas cylinder is installed stably. At the same time, the elastic movement gap provides elastic movement space for the elastic sheet, so that the gas cylinder mounting cavity can install gas cylinders of different lengths, which has a wide range of applications.
[0012] Specifically, the gas cylinder limiting wall is inverted L-shaped, and includes a connecting part and a limiting part. One end of the elastic sheet is connected to one side of the connecting part, and a limiting opening is opened on the limiting part. The other end of the elastic sheet extends to the limiting opening and abuts against one side of the limiting opening. There is an elastic movement gap between the elastic sheet and the other side of the connecting part. The cooperation between the other end of the elastic sheet and the limiting opening effectively limits the maximum deformation of the elastic sheet, avoids excessive deformation of the elastic sheet, and is conducive to the stable use of the elastic sheet and ensures the service life of the elastic sheet.
[0013] Specifically, the actuating element is an actuating rod with a rotating hole in the middle. One end of a connector passes through the rotating hole and connects to the partition plate. The actuating rod has a limiting guide hole, and one end of the limiting guide hole extends into a limiting hole. The limiting guide hole forms the limiting guide track, and the limiting hole forms the limiting part. The other end of the actuating rod extends out of the outside of the furnace body. After one end of the actuating rod is touched, the other end of the actuating rod allows the user to push the actuating rod to rotate again, thereby causing the elastic element to be stretched again, the actuating end to pass through the through-hole of the furnace frame again, and the pushing element to return to its initial state. Furthermore, the limiting guide hole and the limiting hole have simple structures and are relatively easy to manufacture.
[0014] Specifically, the pushing component includes a pushing rod and a gas cylinder pushing end and a gas cylinder limiting end connecting the two ends of the pushing rod. The partition plate has a first guide through hole, a second guide through hole, and a third guide through hole. The pushing rod is located between the actuating rod and one side of the partition plate. One end of a screw passes through the limiting guide through hole, the through hole on the pushing rod, and the first guide through hole in sequence and is screwed to a fixing nut. The screw constitutes the blocking part. The gas cylinder pushing end passes through the second guide through hole and extends into the gas cylinder mounting cavity. The gas cylinder limiting end passes through the third guide through hole and extends into the gas cylinder mounting cavity. The blocking part composed of the screw has a simple structure and is relatively easy to implement. Furthermore, the first guide through hole plays a good limiting and guiding role for the movement of the screw on the pushing rod, the second guide through hole plays a good limiting and guiding role for the movement of the gas cylinder pushing end, and the third guide through hole plays a good limiting and guiding role for the movement of the gas cylinder limiting end, so that the overall movement of the pushing component is stable.
[0015] Specifically, the elastic element is an elastic tension spring, a hook is provided on the other side of the partition plate, and a hook groove is opened on the pushing end of the gas cylinder. One end of the elastic tension spring is hooked on the hook, and the other end of the elastic tension spring is hooked on the hook groove; it is easy to implement and has good implementation effect.
[0016] Specifically, the burner assembly is provided with a flame distributor and a flame distributor cover. The flame distributor has an annular wall extending upward around its perimeter. Multiple inclined flame distributor teeth are fixed on the upper surface of the annular wall, with gaps between adjacent flame distributor teeth. The flame distributor cover is fitted onto the multiple flame distributor teeth to form multiple flame distributor holes. The annular wall, in conjunction with the multiple inclined flame distributor teeth, makes the overall flame emitted from the multiple flame distributor holes have a circular inward swirling effect when the burner assembly is working, resulting in a better implementation effect.
[0017] The beneficial effects of this utility model are as follows:
[0018] (1) This safe portable gas stove will cause the user to place a large pot on the stove rack. The large pot will press down on one end of the actuating component, causing the actuating component to rotate. This will cause the blocking part on the pushing component to disengage from the limiting part of the limiting guide rail. At the same time, under the elastic restoring force of the elastic component, the pushing component, together with the gas cylinder pushing end and the gas cylinder limiting end on it, will move together. This will allow the gas cylinder pushing end to push the gas cylinder installed in the gas cylinder mounting cavity to move, so that the gas cylinder can no longer supply gas to the stove head assembly, that is, cut off the operation of the portable gas stove. This will achieve the effect of restricting the use of large pots on the portable gas stove and ensure the safety of using the portable gas stove.
[0019] (2) The inverted L-shaped gas cylinder installation cavity opening makes it convenient for users to install gas cylinders. At the same time, the installation cover can also seal the opening of the gas cylinder installation cavity well. Furthermore, the rotating connection between the installation cover and the gas cylinder installation cavity is located on one side of the top wall. Therefore, when installing the gas cylinder, the user needs to push the installation cover to rotate with one hand and install the gas cylinder with the other hand. After installation, the user only needs to loosen the installation cover, and then the installation cover can rotate naturally under its own gravity and close on the gas cylinder installation cavity, so that the installation cover can play its heat insulation role well and effectively prevent the gas cylinder surface temperature from being too high, which could lead to the risk of explosion.
[0020] (3) The elastic sheet can abut against the non-outlet end of the gas cylinder, making the installation of the gas cylinder stable. At the same time, the elastic movement gap provides elastic movement space for the elastic sheet, so that gas cylinders of different lengths can be installed in the gas cylinder installation cavity, which has a wide range of applications.
