Description

Technical Field

[0001] This utility model belongs to the technical field of kettle sealing structure, specifically a kettle lid sealing structure with a handle. Background Technology

[0002] Nowadays, most kettles on the market have the handle on one side. This is because, in addition to preventing burns, it also saves space. Although it saves space, it does not save effort. Moreover, kettles with the handle on one side usually cannot be used with an open flame. Therefore, kettles with a handle are more convenient and less strenuous for moving around outdoors or between floors at home.

[0003] The most common type of teapot used for open flame is the teapot with a handle, and for aesthetic reasons, the handle is often made very low. However, the disadvantage of the teapot with a handle is that there is almost no seal between the lid and the body. Water vapor can seep out from the edges of the lid and body, which can easily burn your hands. If a seal is necessary, there is usually a sealing ring on the bottom of the lid. However, the sealing ring is in constant contact with water and will eventually become moldy. This is especially problematic for tea lovers, who value both clean water and a positive mindset. People often don't pay attention to cleaning the sealing ring, or it is difficult to clean it, which can affect the quality of drinking water. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing structure for the lid of a kettle with a handle, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sealing structure for the lid of a kettle with a handle, comprising:

[0007] The lid has a fixing structure for fixing it to the pot body, and its lower end face abuts against the outer periphery of the pot body.

[0008] The lower lid, made of a rigid and deformable material, is set on the bottom surface of the upper lid, with its outer edge abutting against the edge of the opening of the pot body.

[0009] In a further technical solution, the middle part of the lower cover is connected to the upper cover by a fastener, and the outer periphery is bent upward to form a raised edge. The raised edge is provided with an abutting part, which abuts against the edge of the opening.

[0010] In a further technical solution, the contact part has an arc-shaped convex edge along the edge of the raised edge.

[0011] In a further technical solution, the opening edge is provided with a downwardly curved edge.

[0012] A further technical solution is that the warped edge and the position near the fixing member form two force points, one above the other, and the elastic part located between the two is bent and contracts inward when subjected to force.

[0013] In a further technical solution, the bottom surface of the upper cover is provided with an elastic element, and the lower end surface of the elastic element abuts against the inner side of the elastic part.

[0014] In a further technical solution, the upper cover is in the shape of a "plate" and extends downward near the opening of the pot body to form a protrusion, and the elastic element is provided at the protrusion.

[0015] In a further technical solution, the elastic element is elastic silicone or a spring.

[0016] In a further technical solution, the fixing element is a screw, which passes through the upper cover and is threadedly connected to the lower cover.

[0017] In a further technical solution, the fastener is a snap-fit ​​component, which is fixed on the lower cover, and the upper cover is provided with a matching snap hole.

[0018] In a further technical solution, the fixing structure includes a cover plate, the upper cover is installed below the cover plate, and two pins are slidably connected inside the cover plate. The two pins are L-shaped and their ends can extend out of the upper cover. A spring is provided between the two pins.

[0019] In a further technical solution, the lower end face of the cover plate is provided with an annular flange, which corresponds to the upper edge of the upper cover.

[0020] In a further technical solution, the outer edge of the upper cover is provided with a flange, the flange forms a slot, and a locking block is provided on the outer side of the annular flange, the locking block engaging with the slot.

[0021] The beneficial effects of this utility model are:

[0022] When in use, the lower lid first contacts the kettle body. In the initial state, the outer diameter of the lower lid is slightly larger than the diameter of the opening, so the lower lid cannot be directly inserted into the opening. Then, the lower lid is forced into the opening by force, causing the outer circumference of the lower lid to deform and shrink. The outer circumference of the lower lid abuts against the edge of the opening to form the first sealing layer. Then, the whole thing continues to move down so that the lower end face of the upper lid abuts against the outer circumference of the kettle body to form the second sealing layer. Finally, the upper lid is fixed to the kettle body by a fixing structure, so that the state of the lower lid abutting against the edge of the opening does not change. There is no need to use sealing rings or threads. These two sealing layers can achieve a good sealing effect and keep the water clean.

[0023] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Please refer to Figure 1-5 ;

[0032] The sealing structure of the kettle lid described in this utility model aims to improve the sealing performance between the kettle lid and the kettle body 31, preventing water vapor from seeping out from the edges. Before that, it should be noted that in the prior art, the common sealing method is also threaded connection. However, too many threads make it inconvenient to remove the kettle lid, and too few threads will still cause steam leakage. Therefore, the threaded connection method is more commonly used in thermos flasks and portable flasks, but rarely in kettles. Therefore, the structure set in this utility model is a new sealing structure other than the threaded connection method. Specifically, it includes an upper cover 1 and a lower cover 41. The upper cover 1 is used to fix it to the kettle body 31. Specifically, it can be fixed by a buckle similar to that of a pressure cooker, as long as it can be easily fixed. The lower cover 41 is made of a rigid and deformable material and is set on the bottom surface of the upper cover 1. There is a gap between the upper cover 1 and the lower cover 41 to provide space for the deformation of the lower cover 41.

[0033] In use, the lower cover 41 first contacts the kettle body 31. In the initial state, the outer diameter of the lower cover 41 is slightly larger than the diameter of the opening, so the lower cover 41 cannot be directly inserted into the opening. Then, the lower cover 41 is forced into the opening by force, causing the outer periphery of the lower cover 41 to deform and shrink. The outer periphery of the lower cover 41 abuts against the edge of the opening to form the first sealing layer. Then, the whole thing continues to move down so that the lower end face of the upper cover 1 abuts against the kettle body 31 on the outer periphery of the opening to form the second sealing layer. Finally, the upper cover 1 and the kettle body 31 are fixed by the fixing structure 2, that is, the state of the lower cover 41 abutting against the edge of the opening will not change. There is no need to use sealing rings or threads. These two sealing layers can achieve a good sealing effect and keep the water clean.

[0034] It should be noted that since this is a kettle, both the upper lid 1 and the lower lid 41 are made of metal, and the vent is located on the kettle body 31, which is away from the handle to prevent burns.

[0035] Preferably, the lower cover 41 is connected to the upper cover 1 in the middle by a fastener 51, and the outer periphery is bent upward to form a raised edge 42. The raised edge 42 is provided with an abutting part 43, which abuts against the edge of the opening. In this embodiment, the abutting part 43 is on the outer side of the raised edge 42. By raising it, the edge position can be deformed better. Moreover, after being forcefully inserted into the opening, the raised edge 42 will have a tendency to return to its original position in the opposite direction, thereby maintaining the abutting state and keeping the sealing state.

[0036] In another embodiment, the contact part 43 is provided with an arc-shaped protrusion along the edge of the raised edge 42. The main function of the arc-shaped protrusion is to strengthen the part and prevent the raised edge 42 from undergoing irreversible deformation, thereby causing poor sealing performance.

[0037] In addition, a downward-curved edge 32 is provided at the edge of the opening. When the lower cover 41 is forcefully inserted into the opening, the arc-shaped convex edge abuts against the edge 32. The main function is that the arc-shaped convex edge has high strength and is not prone to irreversible deformation. Moreover, it can have a better fit with the edge 32, thus improving the sealing performance.

[0038] In one embodiment of the present invention regarding the lower cover 41, the warped edge 42 and the position near the fixing member 51 form two stress points, one above the other. The elastic part 44, which is bent between the two, will deform itself when the warped edge 42 is squeezed, and will also apply pressure to the elastic part 44. When the elastic part 44 is squeezed, the two stress points will shift slightly up and down, which is equivalent to storing the elastic force. When the lid is removed, the elastic part 44 will reset and stretch outward, thereby restoring the lower cover 41 to its initial state. By setting the elastic part 44, the lower cover 41 is made more durable, and at the same time, irreversible deformation caused by long-term use is avoided.

[0039] Based on the above embodiments, some gaps are provided between the upper cover 1 and the lower cover 41, which will cause the lower cover 41 to wobble and not be compact enough. Therefore, an elastic member 12 is provided on the bottom surface of the upper cover 1. The lower end surface of the elastic member 12 abuts against the inner side of the elastic part 44. The elastic member 12 compensates for the looseness caused by these gaps. In addition, the elastic member 12 can be compressed during use, and can also provide assistance when the lower cover 41 is reset.

[0040] In this embodiment of the utility model, the lower cover 41 has a concave shape, and the upper cover 1 adopts the same design. The upper cover 1 is in the shape of a "plate" and extends downward to form a protrusion 11 near the opening of the pot body 31. The elastic element 12 is provided at the protrusion 11. Preferably, the elastic element 1 can be elastic silicone or a spring.

[0041] In this embodiment of the utility model, the fixing member 51 is a screw, which passes through the upper cover 1 and is threadedly connected to the lower cover 41; or the fixing member 51 is a snap-fit ​​member, which is fixed on the lower cover 41, and the upper cover 1 is provided with a snap-fit ​​hole 13 that cooperates with it, so that it can be detachably connected by snap-fit.

[0042] Regardless of the method used, the final result is a detachable connection between the upper cover 1 and the lower cover 41. During the boiling process, some water vapor will inevitably enter the gap between the two, which may cause the elastic element 12 to become moldy. These are invisible and will not attract people's attention. However, after a period of use, when people want to clean these areas, they can do so by disassembling the two parts. Moreover, since the elastic element 12 is exposed, it can be replaced, etc.

[0043] One embodiment of the fixing structure 2 of this utility model specifically includes a cover plate 21, an upper cover 1 installed below the cover plate 21, and two pins 22 slidably connected inside the cover plate 21. The two pins 22 are L-shaped and can extend out of the upper cover 1 at both ends. A spring 23 is provided between the two pins. Of course, two holes corresponding to the pins 22 are provided on the pot body 31. By pressing the two pins 22 at the same time, both are retracted inward, and then the pot lid is combined with the pot body 31. After that, the two pins 22 are released and extended outward under the action of the spring 23 and then inserted into the holes to lock the position of the pot lid.

[0044] Furthermore, since part of the upper cover 1 is in contact with the outer side of the pot body 31, it may undergo irreversible deformation after long-term use, which may affect the sealing performance. Therefore, the lower end face of the cover plate 21 is provided with an annular flange 24, which corresponds to the upper edge of the upper cover 1. There is a gap between the annular flange 24 and the upper cover 1 to provide space for the deformation of the upper cover 1. The part of the annular flange 24 corresponding to the upper cover 1 is the part of the upper cover 1 that is in contact with the pot body 31. Therefore, after the pot cover and the pot body 31 are combined, the upper cover 1 will deform and lift up, and then contact the annular flange 24 to form a limit.

[0045] Furthermore, the outer edge of the upper cover 1 is provided with a flange 14, the flange 14 forms a slot 15, and the outer side of the annular flange 24 is provided with a locking block 25, which engages with the slot 15. Of course, a notch is formed at the flange 14 for the locking block 25 to enter the slot 15. The cover plate 21 and the upper cover 1 can be fixed by rotating relative to each other.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
