Description

Technical Field

[0001] This invention relates to the field of portable water boiling and cooking equipment, and in particular to a portable water boiling and cooking equipment. Background Technology

[0002] Outdoor camping is a popular leisure activity. When camping outdoors, people often go to forests or parks near flowers, trees and shrubs. In order to obtain hot water, users often boil water by burning charcoal. Boiling water with an open flame is inconvenient, and open flames are prohibited in forests or parks for fire prevention. Boiling water with an open flame poses a fire hazard.

[0003] For some users, they carry a portable rechargeable battery and then pair it with a plugged-in water-boiling device. While this solves the problem of open flame, carrying both devices together creates structural redundancy. It requires an extra table to place the water-boiling device and the portable rechargeable battery, and the water-boiling device has a single function, which can only be used to boil water.

[0004] For portable charging and discharging batteries, according to the requirements of household appliance safety regulations, to prevent the risk of misoperation or short circuit, devices with multiple external power interfaces must ensure that different power interfaces cannot be connected simultaneously. In existing technologies, isolation protection for multiple charging interfaces often uses independent covers or mechanical shields. However, such structures often have the following drawbacks: First, the covers or shields are independent of each other, and users may open multiple interface protection covers simultaneously, posing a risk of misconnection; second, some designs use complex electronic locks or sensor interlocking systems, which, while achieving interlocking functionality, are structurally complex, costly, and rely on circuit control, resulting in insufficient reliability in extreme environments.

[0016] The beneficial effects of this invention are as follows: (1) The present invention provides a portable water-boiling and cooking device that, through the cooperation of a lower coupler, an upper coupler, a heating element, and a battery, can boil water and cook food. It can also be used as a portable battery, making it suitable for outdoor use. The device has a high degree of integration and is simple to carry. It integrates a large-capacity battery, an inverter, and a heating appliance into one unit, forming a multi-functional portable energy cooking platform. Users only need to carry one main unit and can flexibly meet various cooking needs such as boiling water, cooking hot pot, and grilling food in different scenarios by changing different dedicated heating appliances (such as kettles, hot pot pots, and barbecue pans). This completely solves the problems of space occupation, weight burden, and single function caused by carrying multiple independent devices in traditional solutions, and greatly improves the convenience of outdoor activities and emergency use.

[0017] (2) By setting up a water guide column, if there is water on the coupling base, the water will flow along the middle of the water guide column to the drain hole at the bottom and be discharged, so that the water is isolated from the inverter and prevents damage to electronic equipment such as control circuit board and inverter.

[0018] (3) The battery fixing structure is directly integrated into the housing of the portable heating device, realizing the integration of the battery and the heating device. This solves the redundancy problem of users having to carry separate batteries and water-boiling devices, reduces the number and volume of items to be carried, and improves the portability for outdoor use. The fixing cover and the bottom shell are welded together, making the structure sturdy and durable. Through a specially designed locking part and locking bolts, the battery can be firmly pressed into the fixing groove from above and the side, effectively preventing the battery from loosening, shaking, or falling off during device movement or use, ensuring the reliability of the connection and safety of household appliances.

[0019] (4) Through a purely mechanical structure involving sliding or rotation, physical interlocking between the DC charging interface and the AC charging interface is forcibly achieved. In any state, only one charging interface can be exposed and used, while the other interface is reliably covered by the cover plate, fundamentally eliminating the possibility of both power interfaces being exposed simultaneously due to misoperation. This fully complies with the requirements of household appliance safety regulations for the isolation of multiple power interfaces and significantly improves the inherent safety of the equipment.

[0023] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0027] like Figures 1 to 7 , Figures 10 to 12 As shown, this embodiment provides a portable water-boiling and cooking device, which is a highly integrated outdoor multi-functional device that combines the functions of a power source, water boiling, and cooking. It is particularly suitable for outdoor scenarios such as camping and picnics.

[0028] The device includes a generally rectangular shell 1. Shell 1 is composed of a top shell 11, a bottom shell 12, a front shell 13, a rear shell 14, a left shell 15, and a right shell 16. The shells are connected by screws to form a sturdy and relatively airtight enclosure. A handle 17 is fixedly provided on the outside of shell 1 for easy carrying. In this embodiment, the handle 17 is located on either the left shell 15 or the right shell 16.

[0029] The internal space of the casing 1 mainly houses the following core components: Battery 2, a high-capacity lithium-ion battery pack, serving as the energy source for the entire device; Control circuit board 3, responsible for the overall power distribution, charging and discharging management, heating control, and safety protection of the device; Inverter 4, used to convert the DC power output from Battery 2 into 220V AC power to supply power to external electrical appliances.

[0030] A lower coupler 5 is located on the top of the housing 1. The lower coupler 5 is a coupling base 51 that is electrically connected to the control circuit board 3. Users can select different heating appliances as needed, such as kettles, hot pots, or barbecue grills. Each of these heating appliances has an upper coupler 53 at its bottom that matches the lower coupler 5, and a heating element (not shown) is installed inside the appliance. When the heating appliance is placed on the lower coupler 5, the upper coupler 53 and the lower coupler 51 are electrically connected, supplying current to the heating element, which then heats the water or food inside the appliance. This design achieves "multi-purpose functionality," greatly expanding the device's capabilities.

[0031] If liquid overflows and seeps into the housing 1 during boiling or cooking, it will damage the internal electronic components. In order to ensure the safety of the internal electronic components, especially to prevent water overflowing or condensing from the lower coupler 5 from flowing into the housing 1 and damaging the inverter 4 and control circuit board 3, this embodiment is equipped with a water guiding and drainage structure.

[0032] Directly below the coupling base 51, a water guide column 52 is provided. The water guide column 52 is a hollow tubular structure that extends from the top inner wall of the housing 1 to the bottom inner wall.

[0033] The top of the top shell 11 has a first mounting groove 111 for mounting the coupling base 51. A sealing gasket 1111 is fitted around the top of the first mounting groove 111 to prevent water from seeping in from the mounting gap between the coupling base 51 and the shell 1. The coupling base 51 is fixed in the first mounting groove 111 by screws or other fasteners.

[0034] A fixing part 1112 extends inward from the wall of the first mounting groove 111, and a fixing hole 1113 is formed on the fixing part 1112 for mounting the coupling base 51. Specifically, two sets of first retaining plates 1114 are symmetrically arranged near the bottom of the first mounting groove 111, and a first retaining groove 1115 is formed between the two sets of first retaining plates 1114. The top of the water guide column 52 can be precisely inserted into the first retaining groove 1115 to achieve fixation.

[0035] Near its bottom, the water guide column 52 has a wire groove 521. The cable connecting the control circuit board 3 to the coupling base 51 can pass through this wire groove 521, which ensures neat wiring and avoids the cable obstructing the water path.

[0036] An annular baffle 121 is provided on the inner side of the bottom shell 12. A drain hole 122 is provided within the area enclosed by the annular baffle 121. The bottom port of the water guide column 52 is located directly above the area enclosed by this annular baffle 121. Any liquid flowing into the first mounting groove 111 from near the coupling base 51 will fall along the column wall of the water guide column 52 into the annular baffle, and finally be discharged from the bottom drain hole 122 to the outside of the shell 1, thus achieving physical isolation from the internal electronic components.

[0037] The method of securing battery 2 is crucial to the safety and reliability of the device. This embodiment adopts an integrated reinforcement and securing scheme: a fixing cover 21 is welded to the inner bottom surface of the bottom shell 12. The fixing cover 21 is formed by the front cover 211, the rear cover 212, the left cover 213, and the right cover 214, forming a fixing groove 215 that matches the shape of battery 2.

[0038] The top edges of the front cover 211 and the rear cover 212 are bent outward horizontally to form a first flange 216. A first connecting hole 2161 is provided on the first flange 216.

[0039] After the battery 2 is placed in the fixing groove 215, a locking part 6 is placed on top of it. The locking part 6 is formed by bending a metal plate and includes a top surface fitting part 61 covering the top surface of the battery 2 and a side surface fitting part 62 fitting the side surface of the battery 2. At the bottom of the side surface fitting part 62, a second flange 63 is formed by bending it outward horizontally, and a second connecting hole 631 is provided on it, which corresponds to the position of the first connecting hole 2161.

[0040] During installation, the locking part 6 is placed over the battery 2, so that the top contact part 61 and the side contact part 62 press the battery 2 down respectively. Then, the locking bolt (not shown in the figure) is passed through the aligned first connection hole 2161 and second connection hole 631 and tightened. In this way, the battery 2 is firmly restrained in the fixing groove 215, preventing it from jumping up and down or wobbling left and right, ensuring connection stability and safety during transportation and use.

[0041] As a portable power bank, the device needs to provide interfaces for charging and external power supply. The power supply interface 9 is located on the front cover 13. For example... Figure 2As shown, in this embodiment, the power supply interface 9 includes a DC power supply interface 91 and an AC power supply interface 92. The power supply interfaces connect to the control circuit board or the inverter. Specifically, the AC power supply interface connects to the inverter, providing AC power output; the DC power supply interface is a USB or Type-C interface, which connects to the control circuit board and the battery, providing DC power output. Simultaneously, to charge the built-in battery 2, two charging interfaces 7 are provided: a DC charging interface 71 and an AC charging interface 72. The charging interfaces 7 are located on one side of the rear shell 14 and connect to the inverter. The inverter converts the AC power provided by the AC charging interface into DC power to charge the battery. Simultaneously, the inverter can also transform the DC power provided by the DC charging interface to charge the battery. It should be noted that the front shell 13 is equipped with a touch screen display, and the control circuit board 3 is located behind the touch screen display.

[0042] To prevent users from accidentally connecting both charging ports 7 to the power supply at the same time and causing danger, this embodiment designs a mechanically interlocking cover plate 8.

[0043] A second mounting groove 141 is formed on the surface of the housing 1 (such as on the rear housing 14). A DC charging interface 71 and an AC charging interface 72 are mounted side-by-side within this second mounting groove 141. Sliding grooves 1411 are embedded in the side walls of the second mounting groove 141. The main body of the cover plate 8 is a plate 81, with sliders 82 connected to both sides. The sliders 82 are slidably embedded in the sliding grooves 1411, allowing the cover plate 8 to slide.

[0044] Within the second mounting groove 141, a first fixed mounting groove 1414 and a second fixed mounting groove 1415 are arranged side-by-side along its length. This length direction can be horizontal or vertical; in this embodiment, it is vertical. A DC charging interface 71 (such as an interface for connecting a photovoltaic DC power supply) is fixedly installed in the first fixed mounting groove 1414, and an AC charging interface 72 (such as an interface for connecting to mains power) is fixedly installed in the second fixed mounting groove 1415. Parallel sliding grooves 1411 are provided on the inner walls of both sides of the second mounting groove 141 along its length.

[0045] The cover plate 8 is used to selectively cover one of the charging ports 7. It includes a plate body 81 and sliders 82 integrally connected to both sides of the plate body 81. The sliders 82 are slidably embedded in the grooves 1411 on both sides of the second mounting groove, so that the entire cover plate 8 can slide smoothly in a straight line within the second mounting groove along the length direction of the grooves 1411. The plate body 81 is sized to completely cover the opening of the first fixed mounting groove 1414 or the second fixed mounting groove 1415.

[0046] To achieve physical interlocking, the sliding stroke of the cover plate 8 is precisely limited. For example... Figure 1 As shown, when the cover plate 8 slides to its topmost extreme position, its plate 81 completely covers the first mounting slot 1414 where the DC charging interface 71 is located, while the second mounting slot 1415 where the AC charging interface 72 is located is fully exposed and can be inserted. Conversely, when the cover plate 8 slides to its bottommost extreme position, its plate 81 completely covers the second mounting slot 1415 where the AC charging interface 72 is located, while the first mounting slot 1414 where the DC charging interface 71 is located is fully exposed and can be inserted. Due to the size limitation of the plate 81, it can only cover one mounting slot at any extreme position, thus forcibly ensuring that the two charging interfaces 7 will not be exposed at the same time, achieving a purely mechanical interlock. It should be noted that in this embodiment, due to its own weight, the cover plate will be at the bottom of the second mounting groove. When the cover plate is at the top of the second mounting groove 141, it is necessary to keep the cover plate at the top of the second mounting groove 141. Preferably, a magnet 841 can be embedded in the top of the cover plate. Similarly, a magnet 841 can be embedded in the top of the second mounting groove 141 of the housing 1. When the cover plate needs to slide to the top of the second mounting groove to cover the first fixed mounting groove 1414, the cover plate will not fall off due to gravity by magnetic attraction.

[0047] To further enhance the protection level of the interfaces, this embodiment also includes a sealing structure. Specifically, a first sealing plate 711 is connected to the outer edge of the DC charging interface 71, and a second sealing plate 721 is connected to the outer edge of the AC charging interface 72. Correspondingly, a third recess 1412 is provided on both sides of the first fixing mounting groove 1414, and a fourth recess 1413 is provided on both sides of the second fixing mounting groove 1415. Simultaneously, a first recess 811 and a second recess 812 are provided at corresponding positions on the cover plate 8. The third recess 1412 and the fourth recess 1413 provide a clearance for the first sealing plate 711 and the second sealing plate 721 to be flipped open. Similarly, the first recess 811 and the second recess 812 also provide clearance for the first sealing plate 711 and the second sealing plate 721, allowing them to be flipped open.

[0048] like Figure 8 and 9 As shown, in a preferred embodiment of the present invention, a rotating shaft 83 is rotatably connected at approximately the center of the second mounting groove 141. The cover plate 8 is generally L-shaped and is formed by a first flip plate 84 and a second flip plate 85 that are perpendicular to each other and fixedly connected at the connection point. This connection point is fixedly connected to the rotating shaft 83, so that the entire cover plate 8 can rotate around the rotating shaft 83 within the second mounting groove 141.

[0049] like Figure 8 As shown, when the lower AC charging interface 72 is needed, the user can rotate the cover plate 8 upwards. At this time, the second flip plate 85 rotates upwards to a horizontal position, and the first flip plate 84 forms a shielding surface that completely covers the upper DC charging interface 71. Simultaneously, the lower AC charging interface 72 is fully exposed. To achieve stable fixation of the cover plate 8 in the vertical position, a magnet 841 (or an iron material) can be embedded in the top of the first flip plate 84, attracting the corresponding iron material (or magnet 841) on the housing 1 to form a magnetic fixation.

[0050] like Figure 9 As shown, when the upper DC charging interface 71 is needed, the user can rotate the cover 8 downwards. At this time, the first flip plate 84 rotates downwards to a horizontal position, and the second flip plate 85 rotates to a vertical position. The shielding surface formed by the two completely covers the lower AC charging interface 72, while the upper DC charging interface 71 is fully exposed. In this state, the gravity of the cover 8 keeps it stable.

[0051] Through the aforementioned rotational motion, the L-shaped cover 8, using the combination of its two vertical plates 81, can always and only completely cover one of the charging ports 7 at the two extreme positions of rotation, thus achieving a forced mechanical interlock. The operation is intuitive and space-saving.

[0052] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
