Description

Technical Field

[0001] The invention relates to the technical field of cartridge stoves, in particular to a safety device for a portable butane gas stove to prevent the use of oversized vessels. Background Art

[0002] A portable stove is a non-stationary appliance used for direct heating in home kitchens, hotels, and outdoor leisure products. It uses butane gas as its primary fuel, though liquefied petroleum gas and other gases are also acceptable. Also known as a portable butane gas stove or barbecue grill, it's a relatively recent trend, primarily used in homes, outdoor leisure activities, and hotels. They are categorized by appearance into single-burner, double-burner, mini, and ultra-thin models, as well as single-use and dual-use models.

[0003] Today's portable butane gas stoves do not really prevent users from using oversized containers. Once users use oversized containers, they are likely to cover the position of the gas cylinder compartment. During use, the high temperature of the container will be reflected on the gas cylinder in the gas cylinder compartment, causing the temperature of the gas cylinder to rise and cause the gas cylinder to explode, resulting in a very serious safety accident. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a portable butane gas stove safety device to prevent the use of oversized containers, which separates the bottle body from the valve, realizes the bottle removal, and directly cuts off the combustion of the butane gas stove. This directly avoids the heat reflection caused by oversized containers covering the stove body, causing the bottle body to overheat and explode, and realizes more direct and effective safe use of the portable butane gas stove.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a portable butane gas stove safety device for preventing the use of oversized utensils, including a stove body, a burning end is provided on one side of the stove body, a placement end is provided on the other side of the stove body, a valve is installed in the placement end, an igniter is installed on the valve, a bottle body is placed in the placement end, a side panel is provided at the connection between the placement end and the burning end, a limiting plate is slidably installed on one side of the side panel, one end of the limiting plate is provided with an abutting plate abutting the bottom of the bottle body, the bottle mouth of the bottle body abuts on the valve, an operating panel is installed on the side panel, the operating panel includes a movable part hingedly installed on the side panel, the rear end of the movable part is provided with a movable groove inclined longitudinally forward, the other end of the limiting plate is movably installed in the movable groove, a pressing part is formed at the front end of the movable part, and a ejection part protruding from the top surface of the stove body is provided at the rear end of the movable part.

[0006] As a preferred technical solution of the present invention, the ejection portion is specifically a raised top plate, the raised top plate is integrally formed with the movable portion, and the upper end of the raised top plate protrudes from the furnace body and is tilted backward.

[0007] As a preferred technical solution of the present invention, the ejection part is specifically an auxiliary top sheet, which is hingedly mounted on the side panel, and the lower end of the auxiliary top sheet abuts against the end of the movable part, and the side of the auxiliary top sheet abutting against the movable part is located at the rear end of the hinge of the auxiliary top sheet.

[0008] As a preferred technical solution of the present invention, a spring is provided on the side of the side plate close to the combustion end, one end of the spring is fixed to the rear end of the side plate, and the other end of the spring is fixed to the front end of the limit plate.

[0009] As a preferred technical solution of the present invention, a heat dissipation groove is provided on the side of the placement end away from the combustion end, and there are several heat dissipation grooves that are evenly distributed on the side of the placement end away from the combustion end.

[0010] As a preferred technical solution of the present invention, a buckle groove is provided at the lower end of the operating panel, the buckle groove is provided on the side of the movable part close to the pressing part, and the side panel is provided with a convex buckle that is engaged with the buckle groove.

[0011] As a preferred technical solution of the present invention, the front end of the placement end is provided with a knob installed on the igniter and the valve, and the front end of the placement end is provided with a slide button installed on the pressing part.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. An operating panel is installed on the limit plate, and the limit plate is used to abut the bottle mouth of the bottle body against the valve. A pressing part is provided on one side of the operating panel, and an ejection part is provided on the other side of the operating panel. The ejection part is provided to protrude from the top surface of the furnace body. When an oversized vessel is placed on the combustion end, the bottom end of the vessel will contact the ejection part and press the ejection part downward, driving the movable part to rotate backward, causing the pressing part to bounce up, driving the movable limit plate installed in the movable groove to slide backward along the side plate, thereby separating the bottle body from the valve, achieving bottle removal, and directly cutting off the combustion of the butane gas stove. Therefore, when using the portable butane gas stove, the heat reflection caused by the oversized vessel covering the furnace body is avoided, causing the bottle body to overheat and explode, thereby achieving more direct, effective and safe use of the portable butane gas stove.

[0014] 2. The ejection part is set as an auxiliary top plate, which is hingedly mounted on the side plate and has its bottom end abutted against the movable part, thereby increasing the length of the auxiliary top plate extending from the furnace body and further improving its use effect.
