Description

Technical Field

[0001] This utility model relates to the field of barbecue grill technology, and in particular to a windproof portable gas grill. Background Technology

[0002] Portable gas grills are widely used in outdoor camping, backyard parties, and other similar settings due to their small size, portability, and use of clean energy. Existing portable gas grills typically include a grill body, a grill rack mounted on the grill body, and an openable / closable lid.

[0003] This type of oven lid is typically a one-piece structure, meaning the top cover is integrally connected to the side panels on both sides and the back panel on the rear, and is connected to the rear of the oven body via hinges. When the oven lid is closed, food can be braised, roasted, or kept warm, enabling a variety of cooking methods.

[0004] However, because the existing oven lid is a one-piece structure and lacks wind protection, the entire lid must be completely opened if you need to turn the food, add seasonings, or even just check on it. Each time the lid is fully opened, a large amount of heat and smoke used for grilling is lost instantly, causing drastic temperature fluctuations inside the oven. This not only prolongs cooking time but may also affect the taste and evenness of the food's cooking.

[0005] Therefore, existing portable gas ovens need to be improved to overcome the shortcomings of the existing technology. Utility Model Content

[0006] To overcome the problems existing in related technologies, the purpose of this utility model is to provide a windproof portable gas oven. The windproof portable gas oven designs the oven lid assembly as a structure in which the windproof side wall and the movable cover can be separated, locked, and rotated relative to each other. This overcomes the problem in the prior art where the oven lid is an integral structure, requiring the entire oven lid to be lifted to observe or operate the food during grilling, resulting in a large loss of heat and large temperature fluctuations inside the oven, which affects the cooking effect.

[0007] A windproof portable gas grill includes a grill body, and the windproof portable gas grill also includes a grill cover assembly, the grill cover assembly comprising:

[0008] A connecting base is fixed to the rear of the furnace body;

[0009] Two windproof side panels, the rear parts of which are rotatably connected to the two sides of the connecting base respectively;

[0010] A movable cover plate, the rear two sides of which are rotatably connected to the two windproof side panels respectively, and the front of the movable cover plate is provided with a handle for opening or closing the movable cover plate;

[0011] A locking mechanism is provided for locking or separating the movable cover from the two windproof side panels.

[0012] Furthermore, a first pivot is provided at the bottom of the rear end of the windproof side panel, and the windproof side panel is pivotally connected to the connecting base through the first pivot.

[0013] The movable cover plate is provided with a second pivot at its rear bottom, and the second pivot is coaxially sleeved on the first pivot. The movable cover plate is rotatably connected to the first pivot through the second pivot.

[0014] Two independently rotating components share a single rotation axis, resulting in a highly compact structure across the entire pivoting area with no redundant connectors and a clean appearance. During production and assembly, only one axis needs to be aligned, simplifying the process and improving assembly efficiency and precision. This design achieves dual rotation functionality while maintaining structural compactness, strength, and ease of production.

[0015] Furthermore, a third pivot is provided at the bottom of the rear end of the windproof side panel, and the third pivot is pivotally connected to the connecting base;

[0016] The movable cover is provided with a fourth pivot at the bottom of its rear end, and the movable cover is rotatably connected to the upper rear end of the windproof side panel through the fourth pivot.

[0017] Furthermore, the locking mechanism includes first pin holes respectively provided on the two windproof side panels and a first pin provided on the movable cover plate. Each first pin hole corresponds to a first pin, and the first pin can selectively extend into and engage with the corresponding first pin hole.

[0018] The locking mechanism is specifically designed as a pin-and-hole mating structure. This pin-and-hole locking method is simple in structure, low in manufacturing cost, and achieves locking through mechanical engagement, resulting in a highly reliable and stable connection that is not easily loosened by vibration or accidental contact. This ensures that when the oven needs to be moved or transported as a whole, the oven lid assembly can function as a solid unit, effectively preventing accidental shaking or separation of moving parts, thus improving the overall integrity and safety of the product.

[0019] Furthermore, the locking mechanism also includes an operating component and a drive spring;

[0020] The drive spring is used to apply an elastic force to the first pin to drive the first pin toward the extended position of the movable cover plate.

[0021] The operating component is connected to the first pin via a drive mechanism, and the operating component is used to drive the first pin to move between an extended position and a retracted position.

[0022] By adding a drive spring and an operating component, the locking mechanism has been upgraded from manual to semi-automatic. The drive spring gives the pin a tendency to automatically reset (defaulting to the extended locked position), which greatly improves safety by preventing accidents caused by the user forgetting to lock it. The operating component provides a convenient way to actively unlock against the spring force, realizing intelligent operation of "unlocking on demand and locking automatically," simplifying user operation and improving the user experience.

[0023] Furthermore, the operating component includes a control button and a pull cable. The control button is located on the handle, and the bottom of the control button is connected to one end of the pull cable. The other end of the pull cable is connected to the first pin. When the control button is pressed, the pull cable is pulled, causing the first pin to move from the extended position to the retracted position.

[0024] The operating components are embodied in the control buttons and pull cord located on the handle. This design is highly ergonomic, integrating the "unlocking" and "opening" actions. When the user holds the handle to open the cover, their finger can naturally press the button, which unlocks the cover by pulling the cord and engaging the latch, allowing the cover to be lifted smoothly. This achieves a "one-handed, one-step" opening operation, greatly improving the smoothness and convenience of operation.

[0025] Furthermore, there are two first pins and two first pin holes. The two first pins are respectively located on both sides of the movable cover plate. The control button drives the two first pins to move from the extended position to the retracted position simultaneously through the pull cable.

[0026] A single control button simultaneously drives two pins on both sides via a cable, achieving synchronous locking and unlocking at two points. Compared to single-point locking, dual-point locking makes the connection between the movable cover and the windproof side panels on both sides more stable and symmetrical, preventing unilateral wobbling or twisting, and significantly enhancing the structural rigidity and stability of the furnace cover assembly in the locked state. At the same time, because it is synchronously driven, it retains the convenience of single-handed, single-point operation, achieving a perfect combination of "structural optimization" and "operational simplification".

[0027] Furthermore, the furnace cover assembly also includes a rotation and fixing mechanism, which is used to fix the movable cover plate relative to the windproof side wall at a preset opening angle when the movable cover plate and the windproof side wall are in the unlocked state.

[0028] By adding a rotating fixing mechanism, the problem of the movable cover accidentally closing due to gravity after being unlocked and opened is solved. This mechanism can reliably fix the movable cover at a preset opening angle, thereby freeing the user's hands and allowing them to safely and conveniently perform operations such as turning food and adding seasonings, greatly improving the safety and convenience of use.

[0029] Furthermore, the rotating fixing mechanism includes a second pin and a second pin hole, the second pin and the second pin hole being respectively provided on the movable cover plate or the windproof side panel.

[0030] The rotating fixing mechanism is specifically implemented as a second pin and a second pin hole. This implementation method is similar in principle to the locking mechanism, and also has the advantages of simple structure, low cost, and reliable fixation. By setting multiple second pin holes in different positions, the movable cover can also be easily fixed at multiple preset opening angles, providing users with greater flexibility to adapt to different operational needs.

[0031] Furthermore, the end of the first pin that extends into the first pin hole is chamfered.

[0032] The beneficial effects of this utility model are as follows:

[0033] This utility model provides a windproof portable gas grill, which includes a lid assembly comprising a connecting base, two independently rotatable windproof side panels, a movable cover plate rotatable relative to the windproof side panels, and a locking mechanism. When the locking mechanism locks the movable cover plate and the two windproof side panels, the three form a rigid whole. At this time, the entire lid assembly can be flipped up and down around the connecting base, just like a traditional lid. When the user needs to check or operate the food, the locking mechanism can be unlocked. The two windproof side panels remain stationary (closed to protect the grill body), and the user can easily and independently open the movable cover plate using the handle. During use, it is no longer necessary to completely open the entire lid; only a small portion of the movable cover plate needs to be opened, thus greatly reducing the instantaneous loss of heat and smoky flavor inside the grill and effectively maintaining a constant cooking temperature. This not only ensures uniform cooking and taste of the food and saves gas energy, but also significantly improves the ease of operation and user experience. Attached Figure Description

[0042] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0043] Example 1

[0044] like Figures 1 to 6 As shown, this embodiment provides a windproof portable gas oven, which includes an oven body and an oven cover assembly located at the rear of the oven body.

[0045] The furnace cover assembly includes a connecting base 100, two windproof side panels 200, a movable cover plate 300, and a locking mechanism 400.

[0046] Specifically, the connecting base 100 is a long strip plate that is fixed to the rear wall of the furnace body by screws or rivets. Each end of the connecting base 100 has an upwardly extending pivot lug with a through hole.

[0047] Each windproof side panel 200 is a generally trapezoidal metal plate. At its rear bottom, an inwardly extending first pivot is integrally formed or welded. This first pivot passes through a corresponding through hole on the connecting base 100, enabling a rotatable connection between the windproof side panel 200 and the connecting base 100.

[0048] The movable cover 300 is a top cover that covers the furnace body. On either side of its rear bottom, there is a tubular second pivot. This second pivot is coaxially fitted around the outside of the first pivot and can rotate freely relative to the first pivot. This coaxial design allows the windproof sidewall 200 and the movable cover 300 to rotate around the same axis, resulting in a compact structure. A handle 310 for easy gripping is located at the center of the front of the movable cover 300.

[0049] The locking mechanism 400 is used to lock and unlock the movable cover 300 and the two windproof side panels 200. The locking mechanism 400 includes:

[0050] A first pin hole 420 is provided on the upper front edge of each windproof side panel 200.

[0051] First pins 410 are slidably provided on both sides inside the movable cover plate 300. Each pin has a chamfered head to facilitate smooth insertion into the first pin hole 420.

[0052] Drive spring 430, each first pin 410 is connected to a compression spring, the spring force drives the first pin 410 to always tend to extend out of the side wall of the movable cover plate 300, that is, to the extended position of the first pin hole 420.

[0053] The operating component includes a control button 440 and two cables 450 mounted on the handle 310. The control button 440 can be pressed. One end of each cable 450 is connected to the bottom of the control button 440, and the other end is connected to the tail of a first pin 410. To enable the control button 440 to reset more effectively after being pressed, two return springs 460 are symmetrically arranged inside the button.

[0054] In its natural state, the drive spring 430 pushes the two first pins 410 into the first pin holes 420 on the two windproof side panels 200, thus firmly locking the movable cover 300 and the two windproof side panels 200 into a rigid whole. At this time, the user can hold the handle 310 and open or close the entire furnace cover assembly as a whole, centered on the common pivot at the rear.

[0055] When the user needs to open the top cover separately, simply press the control button 440 on the handle 310. The button pulls both first pins 410 inwards simultaneously via two cables 450, causing them to retract from the first pin holes 420 to the returned position. At this time, the movable cover 300 and the windproof side panel 200 are unlocked. The user can keep the windproof side panel 200 stationary and only flip up the movable cover 300 for observation or operation. After releasing the button, the spring returns to its original position. If the movable cover 300 is already closed, the pins will automatically spring back into the pin holes, relocking the cover.

[0056] This embodiment employs a coaxial sleeve structure with a first pivot and a second pivot, enabling the windproof side panel 200 and the movable cover 300 to rotate on the same axis, resulting in a more compact, highly integrated, and stable overall structure. Its linear pin-type locking mechanism 400 is operated via a control button 440 on the handle 310 linked to a cable 450, providing an intuitive and rapid response, allowing users to easily switch between locking and unlocking with one hand. Simultaneously, the design of automatically resetting and locking the pin using a drive spring 430 ensures that the furnace cover reliably returns to an integrated rigid state when closed, retaining the excellent overall windproof performance of traditional furnace covers while achieving the convenience of independently opening the top cover in a simple and reliable manner.

[0057] Example 2

[0058] like Figures 1 to 6 As shown, this embodiment provides another windproof portable gas oven, which includes an oven body and an oven cover assembly located at the rear of the oven body.

[0059] The connecting base 100 is a long strip of metal fastener, which is securely installed on the upper edge of the rear wall of the furnace body by a number of screws or rivets. Both ends of the connecting base 100 are provided with pivoting structures for rotatable connection, such as pivoting holes or pivoting seats.

[0060] The windproof side panels 200 consist of two symmetrically arranged, roughly trapezoidal metal plates, with a height comparable to the furnace body sidewalls, effectively protecting both sides of the furnace body when the furnace lid is closed. In this embodiment, each windproof side panel 200 has a third pivot at its rear bottom. This third pivot cooperates with the pivoting structure on the connecting base 100 to form a first rotating joint, allowing the two windproof side panels 200 to rotate relative to the furnace body using this axis.

[0061] The movable cover 300 is a plate used to cover the top of the furnace body. A fourth pivot extending outward is provided on each of its two rear bottom sides. Correspondingly, a pivot hole matching the fourth pivot is provided in the upper rear region of each windproof side panel 200 (i.e., away from the third pivot). The fourth pivot passes through this pivot hole, forming a second rotating pair. The windproof side panel 200 rotates about its rear bottom as an axis, while the movable cover 300 rotates relative to the windproof side panel 200 about its upper rear part as an axis. A handle 310 integrating operating functions is also provided at the center of the front part of the movable cover 300.

[0062] In this embodiment, the locking mechanism 400 for locking or separating the movable cover 300 from the two windproof side panels 200 includes:

[0063] A locking tongue is pivotally mounted on the front inner side of the movable cover 300, near its left and right corners, via a pivot. The locking tongue can be an L-shaped or eccentric metal lever. Each locking tongue is equipped with a torsion spring, which drives the locking tongue to always tend towards a locked position (rotated to the position extending beyond the side wall of the movable cover 300).

[0064] On the front inner wall of the two windproof side panels 200, corresponding to the position of the aforementioned locking tongue, a locking groove is respectively opened or stamped. The shape of the locking groove matches the head of the locking tongue in the locked position, and can accommodate and lock the locking tongue.

[0065] A transmission linkage mechanism is installed inside the movable cover plate 300 to synchronously drive the rotation of the two locking tongues. This mechanism can consist of a central drive disc and a linkage connecting the drive disc to the two locking tongues.

[0066] The operating component is a rotary knob or a slider that can slide left and right, mounted on the handle 310. The rotary knob or slider is connected to the aforementioned transmission linkage mechanism (e.g., a central drive disc).

[0067] This embodiment also includes a rotation fixing mechanism for stably fixing the movable cover 300 at a specific opening angle when it is opened independently. Specifically, this mechanism includes: multiple second pin holes arranged in an arc shape, punched or drilled on the side walls of two of the windproof side panels 200 along the rotation trajectory of the fourth pivot. These pin holes correspond to different preset opening angles, such as 30 degrees, 60 degrees, and 90 degrees. A manual second pin is installed on the corresponding side wall of the movable cover 300. This second pin is preferably a spring-loaded pull pin structure, whose pin is extended by an internal spring in its natural state, and retracts when its handle is pulled outwards.

[0068] In its natural state, the two torsion springs act on the two locking tongues respectively, causing them to rotate to the locked position. In this position, the head of each locking tongue extends out of the side wall of the movable cover 300 and is firmly engaged in the locking groove on the corresponding windproof side panel 200. At this time, the movable cover 300 is tightly locked to the two windproof side panels 200 by the two locking tongues on the left and right, forming a rigid whole, which can be flipped over as a whole.

[0069] When the user needs to open the movable cover 300 independently, they need to operate the rotary knob on the handle 310 (e.g., rotate it 90 degrees clockwise) or slide the slider. This operation, through a transmission linkage mechanism, synchronously drives the two latches to overcome the force of the torsion springs, rotating them to the unlocked position (e.g., the latches are fully retracted within the outline of the movable cover 300). Once the latches disengage from the latch slots, the movable cover 300 separates from the windproof side panel 200, and the user can then independently flip the movable cover 300 upwards.

[0070] After closing the movable cover 300, the user can reverse the rotation of the knob or slider. Alternatively, in some designs, the knob / slider itself may have a return spring 460, which will automatically reset upon release. The locking tongue rotates back to the locked position under the action of the torsion spring, re-engaging into the locking slot to complete the locking process.

[0071] This embodiment employs a rotary locking mechanism 400, providing a cable-free 450 and more reliable locking solution. It also optimizes the opening trajectory of the movable cover 300 using a non-coaxial dual-pivot design and adds a rotational fixing mechanism. This allows the user to easily fix the movable cover 300 at multiple preset opening angles after independently opening it, completely freeing the user's hands and solving the problem of needing to hold the cover with one hand and operate the food with the other during the braising or grilling process. This greatly improves the convenience, safety, and operational efficiency of the cooking process.

Any specific values ​​in all examples shown and discussed herein should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0073] Furthermore, it should be noted that the use of terms such as "first" and "second" is merely for ease of distinction, and unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.
