Description

Technical Field

[0001] This utility model relates to the field of portable cooking and beverage appliances, and in particular to a container structure. Background Technology

[0002] With the increasing popularity of portable cooking and drinking containers, more and more users want to be able to heat or blend food or drinks directly in the cup in the office, while traveling or outdoors, such as portable kettles, blending cups, soy milk cups and other products.

[0003] To prevent liquid leakage during transport, these cooking and beverage containers typically require a tight seal between the lid and the container body. However, during heating or stirring, the material inside the container generates a large amount of gas due to heat or high-speed stirring, causing a rapid increase in internal pressure and posing a safety hazard of liquid splashing or container rupture. To balance venting and sealing, existing technologies often use a container lid consisting of an upper and lower cover, each with a venting channel. When rotated and aligned, the two covers communicate with the container's internal cavity to release air; when misaligned, they seal the container. Therefore, before installing the lid, the upper cover must be rotated to align the two venting channels and form a complete venting channel, allowing for timely pressure release during operation.

[0004] This method, which relies entirely on user operation, has obvious drawbacks: if the user forgets or operates improperly, the venting channel may not have been formed when the container starts working, which may still lead to the risk of overpressure. Summary of the Invention

[0005] (a) Technical problems to be solved:

[0006] The present invention aims to provide a container structure to solve the safety hazard of internal overpressure that may occur in existing portable cooking and drinking containers if the user does not open the venting channel in time before installing the container lid, due to poor venting during operation.

[0007] (II) Technical Solution:

[0008] To achieve the above objectives, this utility model provides a container structure, comprising: The container body has an inner cavity for containing materials and a processing component for processing the materials, and is equipped with a position detection element; A container lid, detachably mounted at the opening of the container body, includes: The lower cover is detachably connected to the container body and is provided with a lower exhaust channel and a trigger part; The upper cover is rotatable about the axis of the lower cover to switch between a first position and a second position relative to the lower cover, and the upper cover is provided with an upper exhaust channel; A limiting member is provided between the lower cover and the upper cover, so that when the container cover is not connected to the container body: If the upper cover is in the first position, the lower exhaust channel is aligned with and connected to the upper exhaust channel, then the limiting member allows the lower cover to connect with the container body, and the triggering part triggers the position detection element to close the circuit of the processing unit; If the upper cover is in the second position, the lower exhaust channel is misaligned with the upper exhaust channel, and its exhaust end is blocked by the bottom surface of the upper cover. In this case, the limiting member prevents the lower cover from connecting with the container body, and the triggering part cannot trigger the position detection element, thus keeping the circuit of the processing unit disconnected.

[0009] Further, the limiting member includes a main body and a limiting arm located at the lower end of the main body. An installation cavity is formed between the upper cover and the lower cover. The bottom surface of the installation cavity has a through groove extending to the bottom of the annular sidewall of the lower cover. The main body is disposed within the installation cavity, and the limiting arm passes through the through groove, switching between a yielding state and a blocking state as the upper cover rotates between a first position and a second position. When the limiting arm is in the yielding state, its lower end is hidden or can be retracted into the through groove, allowing the lower cover to be connected to the container body in place; When the limiting arm is in the blocking state, its lower end extends out and beyond the bottom surface of the lower cover, preventing the lower cover from connecting with the container body.

[0010] Furthermore, one of the upper cover and the main body is provided with a clearance portion, and the other is provided with a clearance fitting portion that cooperates with the clearance portion; When the upper cover is in the first position, the yielding part is aligned and engaged with the yielding mating part, allowing the limiting member to move axially upward, so that the limiting arm is in the yielding state; When the upper cover is in the second position, the yielding part is misaligned with the yielding mating part and makes contact with the other limiting part, preventing the limiting member from moving upward and keeping the limiting arm in the blocking state.

[0011] Furthermore, a guide structure is provided between the yielding part and the yielding mating part, and when the upper cover continues to rotate from the first position, the guide structure guides the yielding part to exit the yielding mating part.

[0012] Furthermore, the guide structure includes a first guide surface formed on the clearance portion and a second guide surface formed on the inner wall of the clearance mating portion. When the upper cover continues to rotate from the first position, the first guide surface and the second guide surface cooperate with each other to drive the limiting member to move away from the upper cover.

[0013] Furthermore, an elastic element is provided between the limiting member and the lower cover. The elastic element applies an upward elastic force to the limiting member along the axial direction, so that the limiting arm has a force that always tends to yield.

[0014] Furthermore, the container body has a locking hole at the shoulder edge of the opening. When the container lid is connected to the container body, if the upper cover continues to rotate from the first position to the second position, the lower end of the limiting arm extends into the locking hole to lock the lower cover to the container body.

[0015] Furthermore, the outer periphery of the lower cover is provided with a first mark, and the outer periphery of the upper cover is provided with a second mark; the first mark and the second mark are arranged opposite to each other to indicate whether the upper cover is in the first position.

[0016] (III) Compared with the prior art, the beneficial effects of this utility model are:

[0017] The container structure of this utility model, by setting a limiting member between the lower and upper lids of the container, ensures that during the assembly process before the lid is fully connected to the container body, the limiting member only allows the lower lid to continue connecting to the container body and triggering the position detection element when the upper and lower exhaust channels are aligned and connected, thereby closing the processing circuit. If the two exhaust channels are misaligned and closed, the limiting member will block the lower lid in advance during installation, preventing the triggering part from activating the position detection element, and keeping the processing circuit open. This ensures that the exhaust channels must be connected before the connection and processing can be completed each time the container lid is installed, avoiding the risk of overpressure caused by the lack of an exhaust channel during installation and improving the safety of portable cooking containers.

[0025] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] In the description of this utility model, it should be noted that the terms "center", "middle", "upper", "lower", "left", "right", "inner", "outer", "top", "bottom", "side", "vertical", "horizontal", "first", "second", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, 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 this utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] refer to Figure 1 and Figure 2 This embodiment provides a container structure, including a container body 1 and a container lid 2.

[0029] The container body 1 has an inner cavity 11 for containing materials, and a processing component 12 is provided at the bottom or on the side wall. The processing component 12 can be a heating component, a stirring component, or a component that combines heating and stirring functions.

[0030] The container body 1 is provided with a position detection element 13 at the opening, which is used to detect whether the container cover 2 is correctly installed on the container body 1 and to provide a signal to the control circuit.

[0031] The container lid 2 is detachably installed at the opening of the container body 1 and consists of a lower lid 21 and an upper lid 22 rotatably connected thereto.

[0032] The lower cover 21 is detachably connected to the container body 1, for example, by threaded connection, swivel snap connection or other equivalent sealing connection, and the lower cover 21 forms a lower exhaust channel 211 communicating with the inner cavity 11.

[0033] A trigger part (not shown) is provided on the lower cover 21. When the container cover 2 is installed from the unconnected state to the connection termination position with the container body 1, the trigger part makes mechanical contact or inductive coupling with the position detection element 13, thereby triggering the position detection element 13 and closing the working circuit of the processing unit 12; When the container lid 2 is not connected to the position, the triggering part and the position detection element 13 do not meet the triggering conditions, the position detection element 13 is not triggered, and the circuit of the processing unit 12 remains disconnected.

[0034] The specific way the trigger part and the position detection element 13 are matched can adopt common structures in the field, such as the pressure surface matching the micro switch, the magnet matching the magnetic control switch, the magnet matching the induction coil, etc., all of which can achieve the same detection function, and no limitation is made here.

[0035] refer to Figure 3 and Figure 4 The upper cover 22 can rotate relative to the lower cover 21 about the axis of the container cover 1, so as to switch between a first position and a second position relative to the lower cover 21. An upper exhaust channel 221 communicating with the outside is formed inside the upper cover 22. When the upper cover 22 is in the first position, the upper exhaust channel 221 is aligned and connected with the lower exhaust channel 211, allowing the gas in the inner cavity 11 to be discharged smoothly. When the upper cover 22 is in the second position, the upper exhaust channel 221 is misaligned with the lower exhaust channel 211, and at this time the gas outlet end of the lower exhaust channel 211 is closed by the bottom surface of the upper cover 22.

[0036] A limiting member 3 is provided between the lower cover 21 and the upper cover 22, so that when the container cover 2 is not connected to the container body 1:

[0037] refer to Figure 3 and Figure 1 If the upper cover 22 is in the first position, the limiting member 3 allows the lower cover 21 to be connected to the container body 1. At this time, the triggering part 212 triggers the position detection element 13 and controls the circuit of the processing unit 12 to close.

[0038] refer to Figure 4 and Figure 1 If the upper cover 22 is in the second position, the limiting member 3 prevents the lower cover 21 from being connected to the container body 1, so that the triggering part 212 does not trigger the position detection element 13, thereby keeping the circuit of the processing unit 12 in an open state.

[0039] This ensures that the container cover 2 can be installed in place with the container body 1 and the processing unit 12 can be powered on only when the upper exhaust channel 221 and the lower exhaust channel 211 are connected, fundamentally avoiding the risk of overpressure caused by forgetting to exhaust.

[0040] like Figure 5 As shown, the limiting member 3 includes a main body 31 and a limiting arm 32 located at the lower end of the main body 31. An installation cavity 23 is formed between the upper cover 22 and the lower cover 21. The bottom surface of the installation cavity 23 has a through groove 24 extending to the bottom of the annular sidewall of the lower cover 21. The main body 31 is located within the installation cavity 23, and the limiting arm 32 passes through the through groove 24. The limiting arm 32 can switch between a yielding state and a blocking state as the upper cover 22 rotates.

[0041] Continue to refer to Figure 3 When the upper cover 22 rotates to the first position, the limiting arm 32 is in a yielding state, which is hidden or can be retracted in the through groove 24, and does not obstruct the connection between the lower cover 21 and the container body 1. At this time, the trigger part 212 can smoothly trigger the position detection element 13, so that the circuit of the processing unit 12 is closed and it works normally.

[0042] Continue to refer to Figure 4 When the upper cover 22 rotates to the second position, the limiting arm 32 is in a blocking state, with its lower end extending downward from the through groove 24 and beyond the bottom surface of the lower cover 21. During the installation of the container cover 2, it will contact the shoulder edge 14 of the container body 1 before other parts of the lower cover 21, causing abutment interference. As a result, the lower cover 21 cannot continue to be positioned downward, the connection with the container body 1 is blocked, and the trigger part 212 cannot approach and trigger the position detection element 13, keeping the circuit of the processing unit 12 disconnected and preventing accidental activation when exhaust is obstructed.

[0043] like Figures 3 to 6 As shown, to enable the limiting arm 32 to switch between the yielding state and the blocking state, the main body 31 is provided with a yielding part 33, and the upper cover 22 is provided with a yielding mating part 222 that cooperates with it. The "yielding part" and "yielding mating part" referred to herein are structures that provide axial movement space for the limiting member 3 when the upper cover 22 is in the first position, so that it is in the yielding state.

[0044] When the top cover 22 rotates to the first position, the clearance part 33 aligns with and cooperates with the clearance mating part 222, allowing the limiting member 3 to move upward along the axial direction, so that the limiting arm 32 is in the clearance state; when the top cover 22 rotates to the second position, the clearance part 33 and the clearance mating part 222 are misaligned and form a limiting contact with the bottom surface of the top cover 22, restricting the axial upward movement of the limiting member 3, so that the limiting arm 32 remains in the blocking state.

[0045] The clearance portion 33 and the clearance mating portion 222 can adopt various structural forms, as long as they allow the limiting member 3 to move axially during alignment and restrict its movement during misalignment. For example, the clearance portion 33 can be any protrusion such as a cylindrical boss, a hemispherical protrusion, a wedge key, or a cam surface; the clearance mating portion 222 can be a corresponding recess such as a through hole, a hemispherical recess, a keyway, or a clearance groove, but is not limited to these.

[0046] It is understood that the relative arrangement of the clearance portion 33 and the clearance fitting portion 222 is not limited to the above embodiment. The clearance portion 33 may be provided on the bottom surface of the upper cover 22, while the clearance fitting portion 222 may be provided on the main body portion 31.

[0047] To facilitate the retraction of the retraction part 33 from the retraction mating part 222, so that the upper cover 22 can continue to rotate from the first position to the second position, a guide structure is also provided between the retraction part 33 and the retraction mating part 222.

[0048] Specifically, the outer surface of the clearance portion 33 forms a first guide surface 331, and the inner wall of the clearance mating portion 222 forms a corresponding second guide surface 2221.

[0049] When the top cover 22 continues to rotate from the first position in a predetermined direction, the first guide surface 331 and the second guide surface 2221 engage with each other to generate an axial force that causes the limiting member 3 to move away from the top cover 22, thereby allowing the receptive part 33 to smoothly exit the receptive engagement part 222, thus ensuring the continuous rotation of the top cover 22.

[0050] The first guide surface 331 can be a chamfer, a bevel, or an arc surface, and the second guide surface 221 is an inclined surface or a curved surface that matches it; the shape and angle of the two can be determined according to the matching stroke and process requirements, and are not limited to a single form.

[0051] In this embodiment, to enable the limiting member 3 to automatically retract to the yielding state, an elastic member 34 is provided between the lower cover 21 and the limiting member 3. The elastic member 34 is preferably a metal helical compression spring, but leaf springs, wave springs, or other elastic components that can provide axial restoring force can also be selected as needed.

[0052] For example, the lower end of the elastic member 34 can be supported on the bottom surface of the mounting cavity 23 or the shoulder of the through groove 24, and the upper end can abut against the lower surface of the main body 31 of the limiting member 3 (or the annular step formed in the main body), thereby continuously applying an upward elastic force to the limiting member 3 along the axial direction of the container cover 2.

[0053] When the upper cover 22 rotates to the first position, the clearance part 33 aligns with the clearance mating part 222, and the limiting member 3 automatically moves upward along the axis under the action of the elastic member 34, causing the limiting arm 32 to retract into the through groove 24 and be in the clearance state. At this time, the lower cover 21 can be smoothly connected to the container body 1, and the trigger part 212 can trigger the position detection element 13, thereby closing the working circuit of the processing member 12.

[0054] As the top cover 22 continues to rotate from the first position to the second position, guided by the guide structure, the receptive part 33 gradually disengages from the receptive mating part 222, and drives the limiting member 3 to overcome the elastic force of the elastic member 34 and move downward along the axis as a whole, causing the lower end of the limiting arm 32 to extend downward from the through groove 24. Finally, the receptive part 33 abuts against the bottom surface of the top cover 22. At this time, the upward movement of the limiting member 3 is restricted, and the limiting arm 32 remains in a blocking state extending downward from the through groove 24, thereby reliably preventing the lower cover 21 from being connected to the container body 1.

[0055] In addition, the cooperation between the elastic element 34, the clearance part 33, and the clearance mating part 222 can also form a slight locking effect. When the user rotates the top cover 22, he will feel a clear tactile feedback, which makes it easy to intuitively judge whether the top cover 22 is in the first position or has left that position.

[0056] refer to Figure 1 In this embodiment, the shoulder edge 14 of the opening is provided with a locking hole 15, the position of which corresponds to the through groove 24 and the limiting arm 32 on the lower cover 21. After the container cover 2 is installed on the container body 1, the lower end of the limiting arm 32 can be inserted into the locking hole 15.

[0057] After the container lid 2 is connected to the container body 1, if the user continues to rotate the upper lid 22 from the first position to the second position, the clearance part 33 and the clearance mating part 222 will be misaligned and drive the limiting member 3 to move down. The lower end of the limiting arm 32 will then extend downward and enter the locking hole 15 to lock the lower lid 21, thereby preventing the lower lid 21 from rotating or loosening relative to the container body 1 during carrying or shaking.

[0058] When it is necessary to remove the container lid 2, the user must first rotate the upper lid 22 back to the first position so that the clearance part 33 and the clearance mating part 222 are realigned. Under the elastic force of the elastic member 34, the limiting member 3 automatically moves upward along the axial direction, and the limiting arm 32 retracts into the through groove 24 and exits the locking hole 15. At this time, the upper exhaust channel 221 and the lower exhaust channel 211 are reconnected, and the inner cavity 11 of the container forms a smooth exhaust path with the outside, automatically releasing residual pressure and preventing hot air or liquid from splashing.

[0059] If the upper cover 22 is rotated to the second position after the container lid 2 is removed, the limiting arm 32 will continue to extend downwards. During reinstallation, the limiting arm 32 will contact and interfere with the shoulder edge 14 of the opening before other parts of the lower cover 21, preventing the lower cover 21 from connecting to the container body 1. The user must rotate the upper cover 22 back to the first position to complete the reinstallation.

[0060] Therefore, the lock hole 15 not only provides a reliable mechanical lock during carrying, but also achieves a comprehensive safety effect of automatic venting and reset and preventing misoperation by forcing the operation sequence of "returning to the first position before disassembly or reinstallation".

[0061] Continue to refer to Figure 1 To facilitate users in intuitively determining the rotation position of the top cover 22, this embodiment provides a position indicator structure on the outer periphery of the container cover 2.

[0062] A first mark 25 is provided on the outer circumferential surface of the lower cover 21, and a second mark 26 is provided on the outer circumferential surface of the upper cover 22. The first mark 25 and the second mark 26 are arranged opposite each other in the circumferential direction. When the upper cover 22 is rotated to the first position, the two are aligned with each other; when the upper cover 22 is deviated from the first position, the two are misaligned. Users can quickly determine whether the upper cover 22 is in the state of alignment and connection of the exhaust channels 211 and 221 by observing the relative relationship between the two marks.

[0063] The first mark 25 and the second mark 26 can be painted with contrasting colors, silkscreened patterns, laser-etched lines, or can be raised and recessed grooves, metal inserts or other visually recognizable markings, and the specific method is not limited.

[0064] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
