Description

Technical Field

[0001] The utility model relates to the field of drinking water equipment, in particular to a cover assembly and a liquid heating device. Background Art

[0002] Currently, there are many types of health-preserving kettles with stewing pots or filter cups on the market, and the shapes and heights of the kettle bodies vary. In order to better cook the ingredients in the stewing pot or filter cup, each health-preserving kettle usually needs to be equipped with a stewing pot or filter cup of appropriate height, which has poor versatility. Utility Model Content

[0003] Therefore, an object of the present invention is to provide a cover assembly and a liquid heating device to at least solve one of the problems existing in the above-mentioned prior art or related art.

[0004] The first aspect of the utility model provides a cover assembly, which includes: a cover body, on which a plurality of first connection parts are spaced apart in the height direction; a material cup for holding materials, the material cup is located below the cover body, and a second connection part is arranged on the material cup, and the second connection part can be detachably connected to any one of the plurality of first connection parts.

[0005] The cover assembly provided by the embodiment of this aspect includes a cover body and a material cup located below the cover body, and the material cup can be connected to the first connection parts at different heights, and thus be located at different positions relative to the cover body. When the cover body is covered on the container body, the material cup can be located at different heights in the container body by connecting to different first connection parts, so that the material in the material cup is fully heated and the cooking effect is improved. Moreover, even if the container body of different heights is replaced, the material cup can be located at an appropriate position in different container bodies by connecting the material cup to different first connection parts, thereby improving the versatility of the cover assembly.

[0006] In addition, the cover assembly provided in the above embodiment of the present application may also have the following additional technical features:

[0007] In some embodiments, the first connection part is continuously distributed around the central axis of the cover body, and the second connection part can be connected to any position of the first connection part on the circumference. When installing the material cup, there is no need to align the first connection part and the second connection part circumferentially, which is conducive to the rapid installation of the material cup on the cover body. Moreover, after the material cup is installed on the cover body, even if the material cup rotates, the second connection part can still maintain a connection relationship with the first connection part, reducing the probability of the material cup falling.

[0008] In some embodiments, there are multiple second connection parts, which are spaced apart along the circumference of the material cup and are all connected to the same first connection part, so that the material cup can be connected to the cover body at multiple azimuth points in the circumference, thereby improving the installation stability of the material cup.

[0009] In some embodiments, the first connecting portion is a buckle portion, and the second connecting portion is an elastic buckle. The elastic buckle can be squeezed by the cover body to deform into an outer shape, and then elastically snap-fit ​​at the buckle portion.

[0010] In these embodiments, the second connection part is an elastic buckle with a certain elastic force, so that in the process of installing the material cup, the elastic buckle can be first squeezed by the cover body to deform outward, and then rebound and snap together at the snap-in part when reaching the selected snap-in part. Since the elastic buckle has elastic force, compared with the first connection part and the second connection part which are both hard structures, compared with forced squeezing and snapping, the user does not need to apply a large external force for installation, and the material cup is easy and quick to install. After the elastic buckle is snapped at the snap-in part, an external force is also required to pull the material cup outward, so that the elastic buckle is deformed and separated from the snap-in part before it can be separated from the material cup, which can ensure the stability of the installation of the material cup while facilitating the rapid disassembly of the material cup.

[0011] In some embodiments, the bottom of the cover body has a connecting column, and the buckle portion is a convex rib formed on the outer periphery of the connecting column; the top of the material cup has an annular connecting wall, and the elastic buckle is arranged on the annular connecting wall. The elastic buckle can cross any convex rib and buckle on the upward side of the rib.

[0012] In these embodiments, a connecting column is provided at the bottom of the cover body, and a convex rib is provided on the periphery of the connecting column to connect with the material cup. The structure is simple and will not affect the stability of the periphery of the cover body covering the container body. An annular connecting wall is provided on the top of the material cup, and the elastic buckle on the annular connecting wall is used to cooperate with the convex rib. The elastic buckle is similar to a cantilever shape and has a protruding buckling structure. When installing the material cup, the connecting column extends into the annular connecting part. As the material cup continues to move toward the direction where the cover body is located, the elastic buckle is squeezed by the convex rib and deforms toward the outer shape, and then passes over the convex rib and resets by its own elastic force, and buckles on the side of the convex rib facing upward. The design of the elastic buckle not only makes it easier to install the material cup on the cover body, but also because the elastic buckle and the convex rib cooperate with each other, the elastic buckle is not easy to separate from the convex rib, and can only be separated under external force, thereby improving the installation stability of the material cup and making the material cup easy to disassemble and assemble.

[0013] Here, the plurality of convex ribs are spaced apart in the height direction of the cover body, that is, spaced apart along the axial direction of the connecting column. If the material cup is connected to the convex rib located at the top, the elastic buckle needs to sequentially cross over the plurality of convex ribs located below, and finally cross over the convex rib located at the top and buckle on the side of the convex rib facing upward. If the material cup is connected to the convex rib located at the bottom, the elastic buckle only needs to cross over the convex rib and buckle on the side of the convex rib facing upward.

[0014] In some embodiments, the bottom of the cover body has a connecting column, and the buckle portion is a card slot formed on the outer periphery of the connecting column; the top of the material cup has an annular connecting wall, and the elastic buckle is arranged on the annular connecting wall. The elastic buckle can be squeezed by the annular connecting wall and then buckled into the card slot.

[0015] This is similar to the above-mentioned embodiment in which the first connecting portion is a convex rib, but the first connecting portion is designed as a slot, which facilitates the elastic buckle to be smoothly buckled in the slot and makes it more convenient to disassemble and assemble the material cup.

[0016] In some embodiments, the number of the first connection parts is 2 to 5. Then the material cup can be selectively connected between 2 positions or even 5 positions of the cover body, which has good versatility.

[0017] In some embodiments, the height difference between two adjacent first connecting parts is between 5 mm and 15 mm. If the height difference between two adjacent first connecting parts is too small, it is not conducive to a large adjustment of the height of the material cup. If the height difference between two adjacent first connecting parts is too large, the height adjustment span of the material cup is large, and it is difficult to adapt to a container body with a small height difference, and it will cause the overall height of the cover body to be too high, occupying a large space. Therefore, the height difference between two adjacent first connecting parts on the cover body is between 5 mm and 15 mm, which makes it easier to adjust the height of the material cup to adapt to a variety of container bodies, and the cover body will not occupy too much space.

[0018] The second aspect of the present invention provides a liquid heating device, comprising: a container body for holding liquid; and a cover body assembly according to any one of the above embodiments, wherein the cover body is arranged at the top opening of the container body, and the material cup extends into the container body.

[0019] The liquid heating device provided in the embodiment of this aspect has the cover assembly of any of the above embodiments, and thus has the beneficial effects of any of the above embodiments, which will not be described in detail here.

[0020] In some embodiments, the bottom of the container body has a heating plate, and the distance between the bottom of the material cup and the heating plate ranges from 5mm to 15mm. Here, the distance between the bottom of the material cup and the heating plate can be adjusted by adjusting the height of the material cup, so that the distance between the two is kept between 5mm and 15mm, so that local overheating will not occur due to a too close distance, and the heating efficiency will not be affected due to a too far distance, and the cooking effect is good.

[0021] Other aspects and / or advantages of the general inventive concept will be partially set forth in the following description, and some will be clear from the description or may be learned through implementation of the general inventive concept. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The following will be combined Figures 1 to 9 The invention discloses a cover assembly and a liquid heating device provided in embodiments of the invention.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, the first embodiment of the utility model provides a cover assembly, which includes a cover body 10, a material cup 20 for holding materials, and a height adjustment assembly 30. The material cup 20 is located below the cover body 10, and the material cup 20 is connected to the cover body 10 via the height adjustment assembly 30, and the height adjustment assembly 30 can adjust the height of the material cup 20 relative to the cover body 10.

[0047] The cover assembly provided in the embodiment of this aspect enables the height adjustment assembly 30 to adjust the height of the material cup 20 relative to the cover body 10. When the cover body 10 is covered on the container body 40, the material cup 20 can be located at different heights in the container body 40 according to the adjustment of the height adjustment device, so that the material in the material cup 20 is fully heated and the cooking effect is improved. Moreover, even if the container body 40 of different heights is replaced, the material cup 20 can be extended into the appropriate height of different container bodies 40, thereby improving the versatility of the cover assembly.

[0048] Here, the material cup 20 is used to hold the material. The material cup 20 can be a stew pot, or a filter cup with mesh. The material cup 20 can be of many types, which are not listed here one by one.

[0049] The cover body 10 is used to cover the top opening of the container body 40, and allow the material cup 20 to extend into the container body 40. Here, the container body 40 can be used as a part of the liquid heating device. For example, when the liquid heating device is a health pot, the container body 40 can be the pot body. The container body 40 can also exist alone. For example, the container body 40 is a water cup, and the cover body 10 covers the cup mouth, and the material cup 20 extends into the water cup. There can be many types of container bodies 40, which are not listed here one by one. When the material cup 20 extends into the container body 40, the liquid in the container body 40 can transfer heat with the material in the material cup 20. When the material cup 20 is a filter cup, the liquid in the container body 40 can also soak the material in the material cup 20.

[0050] In a specific application, if the container body 40 is a part of the liquid heating device, such as a kettle body, the bottom of the kettle body usually has a heating plate 410, and the material cup 20 extends into the container body 40 and needs to be kept within a set range with the heating plate 410, and should not be too close or too far, otherwise it will affect the heating effect. However, the height of the container body 40 in the current liquid heating device is diversified. If the material cup 20 can only be connected to a fixed position of the cover body 10, when the cover body 10 is covered on different container bodies 40, the material cup 20 may be too close or too far from the heating plate 410, affecting the heating effect. In this embodiment, the height adjustment component 30 can adjust the relative position of the material cup 20 and the cover body 10, so as to facilitate the adjustment of the position of the material cup 20 according to the height of the container body 40, thereby facilitating the material cup 20 to always be kept within a set range with the heating plate 410 to ensure the heating effect. Moreover, for manufacturers, the cover body component can adapt to container bodies 40 of different heights, and there is no need to equip different container bodies 40 with different cover body components, which is conducive to reducing the development of new molds and reducing production costs.

[0051] Specifically, the height of the material cup 20 relative to the cover body 10 can be adjusted according to the shape and height of the container body 40, so as to adjust the depth of the material cup 20 extending into the container body 40 when the cover body 10 is placed on the container body 40. For example, if the container body 40 is high, the height adjustment component 30 can be used to move the material cup 20 away from the cover body 10, so that when the cover body 10 is covered on the container body 40, the material cup 20 will not be too far from the bottom of the container body 40. On the contrary, if the container body 40 is short, the height adjustment component 30 can be used to move the material cup 20 close to the cover body 10, so that the material cup 20 will not be too close to the bottom of the container body 40, nor will it exceed the container body 40, thereby improving the versatility of the cover body component.

[0052] In addition, in addition to adjusting the position of the material cup 20 according to the shape and height of the container body 40, the position of the material cup 20 can also be adjusted according to the height of the liquid level in the container body 40. For example, when there is less liquid in the container body 40, in order to ensure that the liquid fully surrounds the material cup 20, the material cup 20 can be kept away from the cover body 10, so that the material cup 20 can be fully in contact with the liquid, and there is no need to add additional liquid to the container body 40, saving energy. If it is necessary to heat the liquid to indirectly heat the material in the material cup 20, since there is less liquid, the heating time of the liquid can also be reduced to improve efficiency. On the contrary, if there is more liquid in the container body 40, the height of the material cup 20 can be appropriately raised to prevent liquid from overflowing. Of course, this is only one way to select the position of the material cup 20. In different situations, the material cup 20 can also select different positions based on other factors, not limited to the above examples.

[0053] Regarding the specific structure of the height adjustment component 30, further, in some embodiments, as Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the height adjustment assembly 30 includes a plurality of first connection parts 310 spaced apart in the height direction of the cover body 10 , and also includes a second connection part 320 disposed on the material cup 20 , and the second connection part 320 is detachably connected to any one of the plurality of first connection parts 310 .

[0054] In these embodiments, a plurality of first connection portions 310 are spaced apart in the height direction of the cover body 10 , and the second connection portions 320 on the material cup 20 are selectively connected to the first connection portions 310 , so that the material cup 20 can be conveniently connected to different heights of the cover body 10 , thereby enabling the material cup 20 to be located at different heights in the container body 40 when the cover body 10 is covered on the container body 40 .

[0055] In some embodiments, Figure 1As shown, the first connection part 310 is continuously distributed around the central axis of the cover body 10, and the second connection part 320 can be connected to any position of the first connection part 310 in the circumferential direction. When installing the material cup 20, there is no need to align the first connection part 310 and the second connection part 320 in the circumferential direction, which is conducive to the rapid installation of the material cup 20 on the cover body 10. Moreover, after the material cup 20 is installed on the cover body 10, even if the material cup 20 rotates, the second connection part 320 can still maintain a connection relationship with the first connection part 310, reducing the probability of the material cup 20 falling.

[0056] As an example, the bottom of the cover body 10 has a connecting column 110, the center line of the connecting column 110 is colinear with the central axis of the cover body 10, the first connecting part 310 is distributed circumferentially around the connecting column 110, and the second connecting part 320 can be connected to any position of the first connecting part 310 in the circumferential direction.

[0057] In some embodiments, Figure 6 As shown, there are multiple second connection parts 320, which are spaced apart along the circumference of the material cup 20 and are all connected to the same first connection part 310. Thus, the material cup 20 can be connected to the cover body 10 at multiple azimuth points in the circumferential direction, thereby improving the installation stability of the material cup 20.

[0058] In some embodiments, the second connection portion 320 is hooked on the first connection portion 310. Here, the material cup 20 is connected to the cover body 10 by hooking, which is easy to operate and can prevent the material cup 20 from falling off the cover body 10.

[0059] In some embodiments, the first connection portion 310 is a buckle portion, and the second connection portion 320 is an elastic buckle. The elastic buckle can be squeezed by the cover body 10 to deform into an outer shape, and then elastically snap-fit ​​at the buckle portion.

[0060] In these embodiments, the second connection part 320 is an elastic buckle with a certain elastic force, so that in the process of installing the material cup 20, the elastic buckle can be first squeezed by the cover body 10 to deform outward, and then rebound and snap at the selected snap position when reaching the snap position. Since the elastic buckle has elastic force, compared with the first connection part 310 and the second connection part 320, which are both hard structures, compared with forced squeezing and snapping, the user does not need to apply a large external force for installation, and the material cup 20 is easy and quick to install. After the elastic buckle is snapped at the snap position, an external force is also required to pull the material cup 20 outward, so that the elastic buckle is deformed and separated from the snap position before it can be separated from the material cup 20, which can ensure the installation stability of the material cup 20 while facilitating the rapid disassembly of the material cup 20.

[0061] In a specific embodiment, Figures 1 to 6As shown, the bottom of the cover body 10 has a connecting column 110, and the buckle portion is a convex rib formed on the outer periphery of the connecting column 110; the top of the material cup 20 has an annular connecting wall 210, and the elastic buckle is arranged on the annular connecting wall 210. The elastic buckle can pass over any convex rib and buckle on the upward side of the rib.

[0062] In this embodiment, a connecting column 110 is provided at the bottom of the cover body 10, and a convex rib is provided on the periphery of the connecting column 110 to connect with the material cup 20. The structure is simple and does not affect the stability of the periphery of the cover body 10 covering the container body 40. An annular connecting wall 210 is provided on the top of the material cup 20, and the elastic buckle on the annular connecting wall 210 is used to cooperate with the convex rib. Figure 6 The elastic buckle is similar to a cantilever shape and has a protruding buckling structure. When the material cup 20 is installed, the connecting column 110 extends into the annular connecting portion. As the material cup 20 continues to move toward the direction of the cover body 10, the elastic buckle is squeezed by the convex rib and deforms into the outer shape, and then passes over the convex rib and resets by its own elastic force, buckling on the side of the convex rib facing upward, refer to Figure 3 and Figure 5 The design of the elastic buckle not only makes it easier to install the material cup 20 on the cover body 10, but also because the elastic buckle cooperates with the convex rib, the elastic buckle is not easy to separate from the convex rib and can only be separated under external force, thereby improving the installation stability of the material cup 20 and making the material cup 20 easy to assemble and disassemble.

[0063] Here, the plurality of ribs are spaced apart in the height direction of the cover body 10, that is, spaced apart in the axial direction of the connecting column 110. If the material cup 20 is connected to the rib located at the top, the elastic buckle needs to sequentially pass over the plurality of ribs located below, and finally pass over the rib located at the top and buckle on the side of the rib facing upward. If the material cup 20 is connected to the rib located at the bottom, the elastic buckle only needs to pass over the rib and buckle on the side of the rib facing upward.

[0064] Furthermore, if Figure 1 As shown, the connecting post 110 is located at the middle of the bottom of the cover body 10, and the diameter of the connecting post 110 is smaller than the maximum outer diameter of the cover body 10. The design of the connecting post 110 will not affect the cover body 10 covering the container body 40.

[0065] Furthermore, if Figure 1 , Figure 7 , Figure 8 and Fig. 9As shown, the convex ribs are distributed circumferentially around the connecting column 110. It is not necessary to align the position of the convex ribs to connect the material cup 20 to the connecting column 110, and the elastic buckle can be buckled at any position of the convex rib circumference, which is convenient for quick installation of the material cup 20. Moreover, after the material cup 20 is installed on the cover body 10, even if the material cup 20 rotates, the elastic buckle can still maintain a matching relationship with the convex rib, reducing the probability of the material cup 20 falling.

[0066] Furthermore, there are multiple elastic buckles, which are distributed circumferentially along the annular connecting wall 210. Then the material cup 20 can be connected to the cover body 10 at multiple points in the circumference by using multiple elastic buckles, thereby improving the connection stability of the material cup 20. As an example, Figure 6 As shown, the number of elastic buckles is 4.

[0067] Figure 7 , Figure 8 and Fig. 9 Different positions of the material cup 20 relative to the cover body 10 are shown respectively. Figure 7 As shown, the connection column 110 below the cover body 10 has three convex ribs, which are distributed circumferentially around the connection column 110. The elastic buckle on the material cup 20 is hung on the convex rib located at the top. At this time, the bottom of the material cup 20 is close to the cover body 10. When the cover body 10 is covered on the container body 40, it can be roughly referred to Figure 2 and Figure 3 ( Figure 2 and Figure 3 The middle connecting column 110 has only two ribs, and the bottom of the material cup 20 is far away from the bottom of the container body 40. Figure 8 As shown, the connection column 110 below the cover body 10 still has the above three ribs, and the elastic buckle on the material cup 20 is hung on the rib in the middle. At this time, the bottom of the material cup 20 is at a certain distance from the cover body 10. When the cover body 10 is covered on the container body 40, it can be roughly referred to Figure 4 and Figure 5 ( Figure 4 and Figure 5 The middle connecting column 110 has only two ribs, and the bottom of the material cup 20 is at a certain distance from the bottom of the container body 40. Fig. 9 As shown, the connection column 110 below the cover body 10 still has the above three convex ribs, and the elastic buckle on the material cup 20 is hooked on the convex rib below. At this time, the bottom of the material cup 20 is far away from the cover body 10. When the cover body 10 is covered on the container body 40, the bottom of the material cup 20 is close to the bottom of the container body 40. Here, different positions of the material cup 20 are shown. Figure 2 and Figure 4The height of the middle container body 40 is designed to be consistent, and the display of the various placement positions of the material cup 20 does not represent the optimal placement position, which can be determined according to actual needs.

[0068] In another specific embodiment, the bottom of the cover body 10 has a connecting column 110, and the buckle portion is a card slot formed on the outer periphery of the connecting column 110; the top of the material cup 20 has an annular connecting wall 210, and the elastic buckle is arranged on the annular connecting wall 210, and the elastic buckle can be squeezed by the annular connecting wall 210 and then buckled into the card slot.

[0069] This is similar to the above-mentioned embodiment in which the first connection portion 310 is a convex rib, but the first connection portion 310 is designed as a slot, so that the elastic buckle can be smoothly buckled in the slot, and the disassembly and assembly of the material cup 20 is more convenient.

[0070] In some embodiments, the number of the first connection parts 310 is 2 to 5. Then the material cup 20 can be selectively connected between 2 positions or even 5 positions of the cover body 10, which has good versatility.

[0071] In some embodiments, the height difference between two adjacent first connecting parts 310 is between 5 mm and 15 mm. If the height difference between two adjacent first connecting parts 310 is too small, it is not conducive to a large adjustment of the height of the material cup 20. If the height difference between two adjacent first connecting parts 310 is too large, the height adjustment span of the material cup 20 is large, and it is difficult to adapt to the container body 40 with a small height difference, and it will cause the overall height of the cover body 10 to be too high, occupying a large space. Therefore, the height difference between two adjacent first connecting parts 310 on the cover body 10 is between 5 mm and 15 mm, which makes it more convenient to adjust the height of the material cup 20 to adapt to a variety of container bodies 40, and the cover body 10 will not occupy too much space.

[0072] Regarding the specific structure of the height adjustment assembly 30, further, in other embodiments, the bottom of the cover body 10 has a connecting column 110, the first connecting portion 310 is a slot (not shown in the figure) horizontally arranged on the outer periphery of the connecting column 110, and the outer periphery of the connecting column 110 also has a vertically extending connecting groove (not shown in the figure), and the slots are connected to the connecting grooves; the second connecting portion 320 is a tongue (not shown in the figure) arranged on the top of the material cup 20, and the tongue can move up along the connecting groove and then rotate to be inserted into any slot.

[0073] In these embodiments, when installing the material cup 20, the insertion tongue can be inserted into the connection groove by aligning the position of the connection groove, and then as the material cup 20 moves toward the direction where the cover body 10 is located, the insertion tongue moves along the connection groove until it reaches the selected position, the material cup 20 is rotated to move the insertion tongue to the corresponding slot, and then the material cup 20 is released, and the material cup 20 is hung on the slot through the insertion tongue. The structure is simple and the processing is convenient.

[0074] Furthermore, the connecting column 110 can be a hollow column. In this case, the slot can radially penetrate the wall of the connecting column 110, and the tongue can extend inward from the top of the material cup 20. In this case, the material cup 20 can be surrounded by the outside of the connecting column 110. The tongue can also extend outward from the top of the material cup 20. In this case, the top of the material cup 20 can be inserted into the connecting column 110.

[0075] Furthermore, the number of the inserting tongues and the connecting grooves are both multiple and distributed one-to-one. Then, the material cup 20 can be hung on the cover body 10 at multiple points in the circumferential direction by using the multiple inserting tongues, thereby improving the installation stability of the material cup 20.

[0076] In other embodiments, the height adjustment assembly 30 may further include a threaded connection structure. For example, a connecting column 110 is provided at the bottom of the cover body 10, an external thread is provided on the periphery of the connecting column 110, and an internal thread is provided on the inner side of the top opening of the material cup 20. The material cup 20 is screwed onto the external thread of the connecting column 110, thereby realizing stepless adjustment of the position of the material cup 20.

[0077] like Figures 1 to 5 As shown, the second aspect of the utility model provides a liquid heating device, comprising: a container body 40 for holding liquid; and a cover body assembly of any one of the above embodiments, wherein the cover body 10 is covered at the top opening of the container body 40, and the material cup 20 extends into the container body 40.

[0078] The liquid heating device provided in the embodiment of this aspect has the cover assembly of any of the above embodiments, and thus has the beneficial effects of any of the above embodiments, which will not be described in detail here.

[0079] In some embodiments, Figure 2 and Figure 4 As shown, the bottom of the container body 40 has a heating plate 410, and the distance X between the bottom of the material cup 20 and the heating plate 410 ranges from 5 mm to 15 mm. Here, the distance X between the bottom of the material cup 20 and the heating plate 410 can be adjusted by adjusting the height of the material cup 20, so that the distance X between the two is maintained between 5 mm and 15 mm, so that local overheating will not occur due to a too close distance, and the heating efficiency will not be affected due to a too far distance, and the cooking effect is good.

[0080] In some embodiments, the liquid heating device is an electric kettle, a health kettle, or a teapot.

[0081] Although the embodiments of the present invention have been described in detail above, those skilled in the art may make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that, in the opinion of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
