Description

Technical Field

[0001] This application relates to the technical field of stoves, and particularly relates to a cartridge stove. Background Art

[0002] A cartridge stove, also known as a portable butane gas stove, is a non-fixed cooking utensil that uses bottled butane gas as the main fuel and can also use gases such as liquefied gas as fuel, and directly heats through a flame. Cartridge stoves are mainly used for family outdoor leisure, hotel supplies, and non-fixed cooking occasions. The designs of cartridge stoves are diverse, including single-eye, double-eye, miniaturized, and ultra-thin types, as well as the distinction between single-use and dual-use cartridge stoves.

[0003] The main components of a cartridge stove include a stove body, a gas cylinder, an igniter, a combustion burner, a control valve, and a pot support. When in use, the user can ignite and adjust the firepower by rotating the igniter knob, and the operation is very simple. The combustion burner of existing cartridge stoves often protrudes from the surface of the stove body, and the pot support is fixedly arranged on the stove body around the combustion burner. Therefore, during the use of the cartridge stove, the wind force in the external environment will directly affect the combustion burner, making the flame of the combustion burner unstable, resulting in situations such as flame shaking and flame extinction, leading to a decrease in the temperature inside the stove and reducing the heating efficiency of the cartridge stove. Especially when used outdoors, the influence of the wind on the cartridge stove is more significant. Summary of the Invention

[0004] The purpose of this application is to provide a cartridge stove with a simple structure, flexible volume, and windproof effect, so as to reduce the influence of the wind force in the external environment on the flame stability of the cartridge stove.

[0005] To achieve the above purpose, the technical solution adopted in this application is: a cartridge stove, including a stove body, a pot support, and a burner arranged inside the stove body. An installation chamber with an opening at one end is arranged on the top end surface of the stove body at the position of the burner. The burner head of the burner is located inside the installation chamber, and the burner head does not protrude from the top end surface of the stove body. The pot support is detachably connected to the installation chamber, and thus the pot support can be positively or inversely inserted into the installation chamber. When the pot support is inversely arranged in the installation chamber, the pot support does not protrude from the top end surface of the stove body.

[0006] As a preference, the pot support includes a surrounding plate and a plurality of stove ears for supporting the pot. The surrounding plate includes a bottom plate and a side plate. Each stove ear is connected to the bottom plate, and the side plate is vertically arranged on the outer edge of the bottom plate. The height of the side plate is not greater than the depth of the installation chamber.

[0007] As another preference, a relief opening for the burner to pass through is provided on the bottom plate, and each furnace ear is arranged around the relief opening. A support portion is provided at the bottom of the inner side wall of the installation chamber. The cookware support can be positively arranged in the installation chamber by abutting and cooperating with the support portion through the bottom plate, or the cookware support can be reversely arranged in the installation chamber by abutting and cooperating with the support portion through the side plate.

[0008] Further preferably, the height of the side plate is equal to the depth of the installation chamber, and the height of the furnace ear is greater than the height of the side plate. When the cookware support is positively arranged in the installation chamber, the side plate does not protrude from the top surface of the furnace body, and the furnace ear protrudes from the top surface of the furnace body; when the cookware support is reversely arranged in the installation chamber, the bottom plate is cooperatively connected and integrated with the top surface of the furnace body.

[0009] Furthermore, a positioning structure is further provided between the cookware support and the inner side wall of the installation chamber. The positioning structure is adapted to separably connect the cookware support to the installation chamber to limit the cookware support in the installation chamber when the external force does not exceed a preset value.

[0010] Furthermore, the positioning structure includes a clamping hole provided on the inner side wall of the installation chamber and an elastic buckle provided on the side plate. The clamping hole is provided in the middle of the inner side wall of the installation chamber, and the elastic buckle is provided in the middle of the side plate, so that when the cookware support is positively arranged or reversely arranged in the installation chamber, the elastic buckle can be embedded into the clamping hole for cooperation.

[0011] Furthermore, a limiting boss is provided at the edge of the relief opening.

[0012] Furthermore, the support portion can be implemented as a support boss, and the support boss is arranged to surround and connect along the inner side wall of the installation chamber in a circle; or the support portion can be implemented as a plurality of support bumps, and each support bump is arranged at intervals on the inner side wall of the installation chamber.

[0013] Furthermore, the size of the support boss protruding from the inner side wall of the installation chamber is 6 mm to 10 mm, or the size of the support bump protruding from the inner side wall of the installation chamber is 6 mm to 10 mm.

[0014] Furthermore, the shape of the bottom plate is adapted to the shape of the installation chamber, and the bottom plate and the installation chamber can be implemented as circular or square.

[0015] Compared with the prior art, the beneficial effects of the present application are as follows:

[0016] In the cartridge stove provided by the present application, the burner is arranged in the installation cavity defined by the tank body, and the burner head does not protrude from the installation cavity. Thus, the burner head of the burner will be blocked by the tank wall of the tank body, and the ambient wind will not directly blow towards the burner head, which can avoid the influence of the ambient wind on the flame of the cartridge stove and phenomena such as flame fluttering and flame extinction, ensuring the heating efficiency of the cartridge stove in the outdoor environment. In addition, the cookware support is detachably arranged on the support part and is positively or reversely embedded in the installation cavity. When the cartridge stove is in use, the cookware support is positively arranged in the installation cavity, and the burner ears in the cookware support protrude from the installation cavity to support the cookware. When the cartridge stove is stored, the cookware support is reversely arranged in the installation cavity, the burner ears in the cookware support are arranged downward, and the bottom plate of the cookware support is cooperatively connected with the stove body to form an integral body without protruding from the installation cavity, reducing the size of the cartridge stove in the height direction, thereby reducing the packaging size of the cartridge stove, and lowering the packaging cost and transportation cost of the cartridge stove.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, in combination with the specific embodiments, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0022] In the description of the present application, it should be noted that for the orientation terms, if there are terms such as "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation and position relationship are based on the orientation or position relationship shown in the drawings, which are only for facilitating the description of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be construed as limiting the specific protection scope of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence.

[0024] The terms "comprising", "having" and any variations thereof in the description and claims of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0025] As Figures 1-3 shown, this application provides a gas stove, which includes a stove body 100, a cookware support 200 and a burner 300. The burner 300 is arranged inside the stove body 100. An installation chamber 110 with an opening at one end is provided on the top end surface of the stove body 100. The burner head of the burner 300 is located inside the installation chamber 110 and does not protrude from the top end surface of the stove body 100. Thus, the burner head of the burner 300 is blocked by the stove body 100, and the ambient wind will not directly blow towards the burner head of the burner 300, avoiding the influence of the ambient wind on the flame of the gas stove and resulting in phenomena such as flame fluttering and flame extinction, ensuring the heating efficiency of the gas stove in the outdoor environment. The cookware support 200 is detachably connected to the installation chamber 110, and the user can set the cookware support 200 forward or upside down inside the installation chamber 110 according to the actual usage situation.

[0026] Furthermore, as Figure 1 shown, a support portion 120 is provided at the bottom of the inner side wall of the installation chamber 110. The cookware support 200 is detachably placed on the support portion 120. When the user uses the gas stove, the cookware support 200 is positively embedded inside the installation chamber 110, and a part of the cookware support 200 protrudes from the top end surface of the stove body 100 to support the cookware. When the user stores the gas stove, the cookware support 200 can be set upside down inside the installation chamber 110, and the bottom of the cookware support 200 does not protrude from the top end surface of the stove body 100, so that the size of the gas stove in the height direction is reduced, and the size of the carton used for packaging the gas stove can also be reduced accordingly, thereby reducing the packaging cost and transportation cost of the gas stove.

[0027] It is worth mentioning that the implementation manner of the support portion 120 is not limited. In Figure 1In the illustrated embodiment, the support portion 120 can be implemented as a support boss. The support boss is disposed around the inner sidewall of the installation chamber 110 in a circumferential manner. The support boss forms a support plane for supporting the cookware bracket 200. The dimension that the support boss protrudes from the inner sidewall of the installation chamber 110 is 6 mm to 10 mm. In some other embodiments, the support portion 120 can also be implemented as a plurality of support bumps. The support bumps are spaced apart on the inner sidewall of the installation chamber 110 to form a support plane for supporting the cookware bracket 200.

[0028] As Figure 1 shown, the cookware bracket 200 includes a surrounding plate 210 and four furnace ears 220 for supporting the cookware. The surrounding plate 210 includes a bottom plate 211 and side plates 212 vertically disposed on the outer edge of the bottom plate 211. A relief opening 230 for the burner 300 to pass through is formed on the bottom plate 211. The four furnace ears 220 are spaced apart and disposed around the relief opening 230. The distance between the furnace ears 220 and the side plates 212 is set to be 11 mm to 15 mm, so as to avoid interference between the furnace ears 220 and the support portion 120 when the cookware bracket 200 is reversely disposed in the installation chamber 110. When the cookware bracket 200 is disposed upright in the installation cavity, the bottom end surface of the bottom plate 211 abuts against the support portion 120, so that the cookware bracket 200 is erected on the support portion 120; when the cookware bracket 200 is reversely disposed in the installation cavity, the top end surface of the side plate 212 abuts against the support portion 120, so that the cookware bracket 200 is erected on the support portion 120.

[0029] The shape of the bottom plate 211 in the cookware bracket 200 is adapted to the shape of the installation chamber 110. The bottom plate 211 is square, and the installation chamber 110 is also square. When the cookware bracket 200 is embedded in the installation chamber 110, the side plates 212 are in contact with the inner sidewall of the installation chamber 110, and the cookware bracket 200 will not slide in the installation chamber 110. Of course, in addition to implementing the bottom plate 211 and the installation chamber 110 as square, the bottom plate 211 and the installation chamber 110 can also be implemented as circular or other shapes.

[0030] In some preferred embodiments, a limiting boss 231 is further disposed at the edge of the relief opening 230. The limiting boss 231 is used to block food residues and liquids on the bottom plate 211, so as to prevent the overflowed food residues and soup from flowing into the interior of the furnace body 100 through the relief opening 230, increasing the cleaning difficulty of the cartridge stove. In other words, the limiting boss 231, the bottom plate 211 and the side plates 212 define a groove, and the overflowed food residues and soup from the cookware can be retained in the groove. When the user cleans, the cookware bracket 200 only needs to be removed from the installation chamber 110 and the cookware bracket 200 can be cleaned and wiped.

[0031] Further, the height of the side plate 212 in the pot support 200 is not greater than the depth of the installation chamber 110, so that when the pot support 200 is placed upright or upside down in the installation chamber 110, the side plate 212 of the pot support 200 does not protrude from the top surface of the stove body 100.

[0032] Preferably, the height of the side plate 212 in the pot support 200 is equal to the depth of the installation chamber 110, that is, the height of the side plate 212 is equal to the distance between the top surface of the stove body 100 and the support portion 120, and the height of the pot ear 220 in the pot support 200 is greater than the depth of the installation chamber 110.

[0033] Based on the above structure, when the pot support 200 is placed upright in the installation chamber 110, the top surface of the side plate 212 is flush with the top surface of the stove body 100, and the pot ear 220 protrudes from the top surface of the stove body 100 and extends outside the installation chamber 110 to support various sizes of pots. If the height of the pot ear 220 is less than the depth of the installation chamber 110, the pot ear 220 will not be able to protrude from the top surface of the stove body 100, and the pot ear 220 can only support pots with a size smaller than the installation chamber 110. Pots with a size larger than the installation chamber 110 will interfere with the installation chamber 110 and cannot be placed on the pot support 200.

[0034] Based on the above structure, when the pot support 200 is placed upside down in the installation chamber 110, the bottom end surface of the bottom plate 211 and the top surface of the stove body 100 are fitted and joined together. While the height dimension of the cartridge stove is reduced, a flat placement plane is formed on the top surface of the stove body 100, and users can place some light items on the top surface of the stove body 100, such as tableware like bowls, plates, chopsticks, etc., or stack multiple cartridge stoves.

[0035] In some preferred embodiments, a positioning structure is further provided between the pot support 200 and the inner side wall of the installation chamber 110. The positioning structure is adapted to detachably connect the pot support 200 to the installation chamber 110 to limit the pot support 200 in the installation chamber 110 when the external force does not exceed a preset value. Specifically, the positioning structure includes a clamping hole 130 provided on the inner side wall of the installation chamber 110 and an elastic buckle 240 provided on the side plate 212. The position of the elastic buckle 240 corresponds to the position of the clamping hole 130. When the pot support 200 is placed in the installation chamber 110, the elastic buckle 240 can be inserted into the clamping hole 130 to limit the pot support 200 in the installation chamber 110. Preferably, the position of the clamping hole 130 is set in the middle of the inner side wall of the groove, and the elastic buckle 240 is provided in the middle of the side plate 212, so that whether the pot support 200 is placed upright or upside down in the installation chamber 110, the elastic buckle 240 can be engaged and matched with the clamping hole 130.

[0036] In addition to being implemented as the snap holes 130 and the elastic snap fasteners 240, the positioning structure can also be implemented as spring balls and arc-shaped limiting grooves, magnetic components, etc.

[0037] In summary, for the cartridge stove of the present application, an installation chamber 110 is provided around the burner 300. The burner head of the burner 300 is located in the installation chamber 110 and does not protrude from the top surface of the stove body 100. The burner head is blocked by the stove body 100, and the ambient wind will not directly blow towards the burner head. Thus, it is possible to prevent the flame of the burner 300 from being blown and shaken or extinguished, improving the stability of the flame of the cartridge stove. When the cartridge stove is in use, the cookware support 200 can be disposed upright in the installation chamber 110. When the cartridge stove is stored, the cookware support 200 can be disposed upside down in the installation chamber 110, reducing the size of the cartridge stove in the stored state and correspondingly reducing the size of the packaging carton of the cartridge stove, thereby reducing the packaging cost and the transportation cost. Moreover, when the cookware support 200 is disposed upside down in the installation chamber 110, the top surface of the cartridge stove is a flat end surface, and some relatively light items can be placed on the top surface of the cartridge stove, such as placing some bowls or plates.

[0038] The foregoing has described the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application.
