Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to a cooking utensil designed with a function of preventing an inner cover from being missed, and aims to ensure the safety and convenience of the cooking utensil during use through mechanical structure innovation. Background Art

[0002] In modern life, cooking utensils such as rice cookers have become indispensable kitchen appliances in the kitchen. In order to facilitate cleaning, the inner covers of these cooking utensils are often designed to be detachable. However, this design also brings a problem: after removing the inner cover for cleaning, users tend to forget to install the inner cover in a hurry or negligence, which directly leads to the loss of control of the internal pressure or steam of the cooking utensils during operation, which may cause food spillage, damage to the utensils, or even safety accidents. Therefore, it is particularly important to develop a cooking utensil that can effectively prevent users from forgetting to install the inner cover while ensuring easy operation and not affecting the normal cooking process.

[0003] In the prior art, although some cooking utensils have tried to prevent the inner cover from missing by adding a reminder device or adopting a special locking mechanism, these solutions are mostly complex in structure, high in cost or affect the user experience. For example, the utility model patent with patent number CN201189077Y realizes the detachability of the cover body through a push button structure, and uses the elastic recovery of the push button structure to prevent the buckle when the cover is not installed. However, this method adds a push button structure, which increases the number of components and the cost, and also reduces the assembly efficiency of the product. For another example, although the patent document with patent number CN203873593U also realizes the detachability of the inner cover and solves the problem of missing installation, the fool-proof structure it sets also increases the complexity and cost of the product. For another example, some products use electronic sensors to detect whether the inner cover is installed, but this increases the complexity of the circuit system and depends on the power supply, which has the risk of failure.

[0004] In summary, the prior art still has some deficiencies in the design of preventing the inner cover from being missed, and a new design scheme is urgently needed to overcome these problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a cooking utensil which prevents the missing installation of the inner cover. The core of the utility model is to cleverly utilize the mechanical structure to realize automatic detection and control of the installation status of the inner cover, ensuring that the cover body can be buckled with the main body only when the inner cover is correctly installed, thereby effectively preventing the safety hazards caused by the missing installation of the inner cover.

[0006] The utility model discloses a cooking utensil for preventing missing inner cover, which comprises a main body, a cover body and a snapping device; the cover body is provided with a detachable inner cover, and the snapping device comprises a snap plate and a snap seat; the snap plate is attached to the cover body and can rotate between a first position and a second position; the snap seat is attached to the main body; the cover body is provided with a floating member that can move up and down; when the inner cover is assembled on the cover body, the inner cover presses the floating member to move it upward, and then presses the snap plate to rotate it from the first position to the second position; when the inner cover is missing from the cover body, the snap plate is maintained in the first position under the action of a force spring; wherein, at the first position, the snap plate leaves the snap seat to prevent the cover body from snapping with the main body; at the second position, the snap plate is suitable for snapping with the snap seat to allow the cover body to snap with the main body.

[0007] Further optimized, a pressing member for the user to press is provided on the cover body, and the pressing member can drive the buckle plate to rotate, so that it is unfastened from the buckle seat, so that the user can open the cover body. The pressing member is arranged above the first end of the buckle plate, which is convenient for pressing operation, and the second end thereof is designed with a buckle suitable for buckling the buckle seat, which enhances the stability of the structure and the convenience of operation.

[0008] The gusset plate is pivotally connected to the cover body, which simplifies the assembly process and improves the durability of the structure. The design of the force spring, whose main body connects the gusset plate and the floating part, ensures that the gusset plate automatically returns to the first position when not pressed by the inner cover, and realizes automatic detection of the installation status of the inner cover.

[0009] In order to improve the user experience, a return spring is connected between the floating part and the pressing member. The return spring applies force to the floating part to make the floating part move downward, so that the floating part can automatically return to its original position after losing the pressure of the inner cover, which is convenient for the next use. At the same time, the perforated design on the cover allows the floating part to pass through and press against the inner cover, ensuring the accuracy and efficiency of force transmission.

[0010] In particular, a pair of magnetic components are provided between the floating part and the inner cover, which utilize the repulsive effect of magnetic force to force the floating part to move away from the inner cover when there is no pressure from the inner cover, thereby further enhancing the effect of preventing missing installation, simplifying the process of users installing the inner cover, and improving the convenience of use.

[0011] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0012] The cooking utensil of the present invention realizes automatic detection and control of the installation status of the inner cover through innovative mechanical structure design, effectively preventing safety hazards caused by missing inner cover. It has a simple structure, low cost and convenient operation, which not only improves the user experience, but also significantly enhances the safety and reliability of the cooking utensil. At the same time, the magnetic design between the floating part and the inner cover, as well as the application of the reset spring, make the entire device more intelligent and user-friendly, providing new ideas and directions for the safety protection technology of cooking utensil.

[0030] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0031] Embodiment 1:

[0032] like Figures 1 to 10 As shown, this embodiment provides a cooking utensil for preventing the inner cover from being missed, which mainly includes a body 1, a cover 2 and a buckle device. The cover 2 has a detachable inner cover 3, so that the inner cover 3 can be easily removed when it needs to be cleaned. The buckle device is used to control the buckle state between the cover 2 and the body 1, and the cover 2 can only be buckled with the body 1 when the inner cover 3 is correctly installed, thereby effectively preventing the safety hazard caused by the missed inner cover 3.

[0033] The buckle device specifically includes a buckle plate 4 and a buckle seat 5. The buckle plate 4 is attached to the cover body 2 and can be in a first position (such as Figure 4 and Figure 5 as shown) and a second position (as Figure 6 and Figure 7 The buckle seat 5 is attached to the body 1 and cooperates with the buckle plate 4 to realize the buckle connection or unbuckle of the cover body 2 and the body 1.

[0034] like Figures 4 to 7 As shown, in order to realize the automatic detection and control of the installation state of the inner cover 3, the cover body 2 is also provided with a floating member 6 that can move up and down. When the inner cover 3 is assembled on the cover body 2, the inner cover 3 will press the floating member 6 to move it upward, and then press the buckle plate 4 to rotate it from the first position to the second position. At this time, the buckle plate 4 is buckled with the buckle seat 5, allowing the cover body 2 to buckle with the main body 1. On the contrary, when the inner cover 3 is not installed on the cover body 2, the buckle plate 4 is kept in the first position under the action of a force spring 7, and the buckle plate 4 leaves the buckle seat 5, preventing the cover body 2 from buckling with the main body 1.

[0035] like Fig.10 As shown, the force spring 7 has a main body 71, and a first leg 72 and a second leg 73 respectively located on opposite sides of the main body 71. The first leg 72 is attached to the pinch plate 4, and the second leg 73 is attached to the floating member 6. Such a design ensures that when the pinch plate 4 is not pressed by the inner cover 3, the floating member 6 can automatically reset to the first position by dragging the pinch plate 4 through the force spring 7, thereby realizing automatic detection and control of the installation state of the inner cover 3. Specifically, the force spring 7 is a torsion spring, and the first leg 72 and the second leg 73 extend from both sides of the main body 71. In this embodiment, there are two first legs 72, which are respectively located at the two ends of the main body 71 spaced apart on its axis, and the second leg 73 extends from the two ends of the main body 71 and is connected as a whole.

[0036] To achieve the above-mentioned purpose, the floating member 6 applies force to the buckle plate through the second support leg so that the buckle plate has a tendency to turn to the second position, which further enhances the ability of the buckle plate 4 to automatically reset when the inner cover 3 is not installed, and will not cause displacement interference between the buckle plate 4 and the pressing member 8, thereby ensuring the stability and reliability of the entire device.

[0037] Further optimized, a pressing member 8 for the user to press is provided on the cover body 2, and the pressing member 8 can drive the buckle plate 4 to rotate, so that it is unfastened from the buckle seat 5, so that the user can open the cover body 2. The pressing member 8 is arranged above the first end of the buckle plate 4, which is convenient for pressing operation, and the second end thereof is designed with a buckle 81 suitable for buckling the buckle seat 5, which enhances the stability of the structure and the convenience of operation.

[0038] The pinch plate 4 is rotatably connected to the cover body 2 by a pivoting manner, which simplifies the assembly process and improves the durability of the structure. The design of the force spring 7, whose main body connects the pinch plate 4 and the floating member 6, ensures that the pinch plate 4 automatically returns to the first position when not pressed by the inner cover 3, and realizes the automatic detection of the installation state of the inner cover 3.

[0039] In order to improve the user experience, a return spring 9 is connected between the floating member 6 and the pressing member 8. The return spring 9 applies force to the floating member 6 so that the floating member 6 moves downward, so that the floating member 6 can automatically return to its original position after losing the pressure of the inner cover 3, which is convenient for the next use. At the same time, the perforation 21 on the cover body 2 allows the floating member 6 to pass through and press against the inner cover 3, ensuring the accuracy and efficiency of force transmission. Specifically, the return spring 9 is a cylindrical spring or other elastic member.

[0040] Embodiment 2:

[0041] On the basis of Example 1, this embodiment further optimizes the interaction between the floating member 6 and the inner cover 3. Specifically, a pair of magnetic components are provided between the floating member 6 and the inner cover 3, and the repulsive effect of the magnetic force is used to force the floating member 6 to deflect under the action of the magnetic force when the inner cover 3 is installed, so that the buckle plate 4 is deflected to a position where it can be buckled with the pot body. In addition, a counterweight can be further installed on the floating member 6 to increase the gravity of the floating member 6, so that when the inner cover 3 is not installed, it can move downward under the action of gravity, thereby driving the buckle plate 4 to deflect to a position where it cannot be buckled with the pot body.

[0042] Specifically, the floating member 6 has a first magnet 61, and the inner cover 3 has a second magnet 31. The magnetic poles of the first magnet 61 and the second magnet 31 are arranged so that a repulsive force is generated between them, so that when there is no pressure from the inner cover 3, the floating member 6 will move away from the inner cover 3 due to gravity and remain in the initial position. When the user correctly installs the inner cover 3, the repulsive force will press the floating member 6, causing the floating member 6 to move upward, thereby triggering the rotation of the buckle plate 4, thereby preventing the cover body 2 from buckling with the body 1.

[0043] Working principle and beneficial effects:

[0044] The cooking utensil of the utility model realizes automatic detection and control of the installation state of the inner cover 3 through an innovative mechanical structure design. When the user forgets to install the inner cover 3, the buckle plate 4 is kept in the first position under the action of the force spring 7, preventing the cover body 2 from buckling with the main body 1, thereby effectively preventing the safety hazard caused by missing the inner cover 3. When the user correctly installs the inner cover 3, the inner cover 3 presses the floating member 6 to move it upward, and then presses the buckle plate 4 to rotate it to the second position, at which time the buckle plate 4 is buckled with the buckle seat 5, allowing the cover body 2 to buckle with the main body 1.

[0045] In addition, the magnetic design between the floating part 6 and the inner cover 3 can make the structure of the cover body 2 simpler and the mold cost lower than that of the return spring 9 structure. Of course, in another embodiment, the magnetic design and the return spring can be used in combination. The user only needs to simply place the inner cover 3 on the cover body 2, and the magnetic force will automatically trigger the rotation of the buckle plate 4 to achieve the buckle connection between the cover body 2 and the main body 1. When the user needs to open the cover body 2, he only needs to press the pressing member 8 to drive the buckle plate 4 to rotate and unfasten it from the buckle seat 5, which is convenient to operate.

[0046] In summary, the cooking utensil of the utility model has the advantages of simple structure, low cost, convenient operation, etc., which not only improves the user experience, but also significantly enhances the safety and reliability of the cooking utensil. At the same time, the design also provides new ideas and directions for the safety protection technology of cooking utensil.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
