Description

Technical Field

[0001] This utility model relates to the field of hot water equipment, and in particular to a vacuum cup. Background Technology

[0002] Vacuum cups are widely used in various daily life scenarios. They can maintain the internal liquid temperature for a long time, meeting users' drinking needs in various environments. Vacuum cups typically use a heating plate at the bottom of the cup to heat the fluid inside, thereby increasing or maintaining the fluid temperature.

[0003] Existing heating plates mainly use conductive posts to connect to external circuits. In some vacuum cups, the conductive posts can be assembled to the heating plate by welding. However, in other vacuum cups, the welding space at the bottom of the cup may be limited, making it inconvenient to weld the conductive posts. In this case, the conductive posts can be assembled to the heating plate by studs, but studs need to be formed at the heating plate position at the bottom of the cup, which affects the arrangement space of the heating circuit on the heating plate and affects the heating uniformity of the heating plate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a vacuum cup that simplifies the assembly of conductive components in the heating element and ensures that the arrangement space of the heating circuit in the heating element is not affected.

[0005] To solve the above-mentioned technical problems, this utility model provides a vacuum cup, including a cup body and a connecting shell. The bottom of the cup body is provided with a heating space, and the side of the connecting shell is provided with an assembly. The connecting shell is connected to the inner side of the heating space through the assembly.

[0006] A heating element is arranged on the side of the cup body facing the connecting shell. A conductive element is arranged between the heating element and the connecting shell. The conductive element forms a connecting surface and a pressing surface. The connecting surface is connected to the connecting shell, and the pressing surface abuts against the heating element.

[0007] As an improvement to the above solution, one end of the assembly is disposed on the connecting shell, and the other end of the assembly forms an inclined mounting portion. The inclined mounting portion extends downward at an angle relative to the connecting shell, and a connecting groove is formed on the inner side of the heating space. The inclined mounting portion is inserted into the connecting groove.

[0008] As an improvement to the above solution, the connecting groove is formed with an assembly slot and a pressing slot, the pressing slot extends horizontally on the inner side of the heating space, and the assembly slot is arranged at an angle relative to the pressing slot.

[0009] As an improvement to the above solution, the side of the connecting shell opposite to the heating element is formed with a pressing surface, and the side of the assembly opposite to the inclined mounting part is pressed against the pressing surface.

[0010] As an improvement to the above solution, the outer peripheral surface of the connecting shell is formed with a pressing step, and the pressing surface is the step surface of the pressing step that is away from the heating element.

[0011] As an improvement to the above solution, it also includes:

[0012] The bottom cover is connected to the bottom of the cup body and is connected to the connecting shell. The bottom cover and the connecting shell enclose a driving cavity. The connecting shell is made of heat-insulating material.

[0013] As an improvement to the above solution, a pressing protrusion is formed on the inner side of the bottom cover, and the pressing protrusion abuts against the assembly on the side facing the connecting shell.

[0014] As an improvement to the above solution, the bottom cover has an insert groove, the bottom of the cup body has a connecting protrusion ring, the insert groove is fitted into the connecting protrusion ring, the bottom cover and the connecting shell both have connecting protrusions, the connecting protrusions have mounting holes, and the bottom cover and the connecting shell are detachably connected through the mounting holes.

[0016] As an improvement to the above solution, the conductive element is formed with a power receiving end, and the connecting shell has a clearance groove formed on the side facing the conductive element, and the clearance groove faces the power receiving end.

[0017] Implementing this utility model has the following beneficial effects:

[0018] In this embodiment, the vacuum cup can be fixed to the heating space by means of an assembly. Since the connecting surface of the conductive component is connected to the connecting shell, and the pressing surface of the conductive component presses against the heating component, the conductive component can be pressed against the heating component by means of the cooperation between the connecting shell and the assembly, ensuring stable contact between the heating component and the conductive component. This facilitates the conductive component to conduct electricity and heat the fluid, while simplifying the assembly method of the conductive component in the heating plate. It does not require the use of studs or other structures for fixing, thereby ensuring that the arrangement space of the heating circuit in the heating component is not affected, and ensuring the uniformity of heating of the fluid in the vacuum cup by the heating component.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0029] In embodiments of this utility model, such as Figures 1 to 5 As shown, the vacuum cup includes a cup body 1 and a connecting shell 2. A heating space 11 is provided at the bottom of the cup body 1, and an assembly 3 is provided on the side of the connecting shell 2. The connecting shell 2 is connected to the inner side of the heating space 11 through the assembly 3. A heating element 4 is arranged on the side of the cup body 1 facing the connecting shell 2. A conductive element 5 is arranged between the heating element 4 and the connecting shell 2. The conductive element 5 forms a connecting surface 51 and a pressing surface 52. The connecting surface 51 is connected to the connecting shell 2, and the pressing surface 52 presses against the heating element 4.

[0030] In this embodiment, the vacuum cup can be fixed to the heating space 11 by the mounting accessory 3. Since the connecting surface 51 of the conductive element 5 is connected to the connecting shell 2 and the pressing surface 52 of the conductive element 5 presses against the heating element 4, the conductive element 5 can be pressed against the heating element 4 by the cooperation of the connecting shell 2 and the mounting accessory 3, ensuring stable contact between the heating element 4 and the conductive element 5. This facilitates the conductive element 4 to conduct electricity and heat the fluid, while simplifying the assembly method of the conductive element 5 in the heating plate. It does not require the use of studs or other structures for fixing, thereby ensuring that the arrangement space of the heating circuit in the heating element 4 is not affected, and ensuring the uniformity of heating of the fluid in the vacuum cup by the heating element 4.

[0031] It should be noted that the heating element 4 is a thick-film circuit applied to the outer bottom wall of the cup body 1, and the conductive element 5 is a conductive electrode sheet. The thick-film circuit is connected to an external circuit through the conductive electrode sheet, so that electricity is applied to the thick-film circuit to generate heat, and the fluid inside the vacuum cup is heated through heat conduction. The thick-film circuit can be formed on the outer bottom wall of the cup body 1 by chemical etching or mechanical removal. The specific shape of the thick-film circuit can be formed according to the actual designed current path to ensure uniform distribution.

[0032] Specifically, to ensure that the assembly 3 can fix the connecting shell 2 in the heating space 11 and improve the contact effect between the conductive component 5 and the heating component 4, such as Figures 3 to 7 As shown, one end of the assembly 3 is disposed on the connecting shell 2, and the other end of the assembly 3 forms an inclined mounting part 31. The inclined mounting part 31 extends downward relative to the connecting shell 2. A connecting groove 12 is formed on the inner side of the heating space 11, and the inclined mounting part 31 is inserted into the connecting groove 12.

[0033] Understandably, since the inclined mounting part 31 extends downward relative to the connecting shell 2, when the fitting 3 is inserted into the connecting groove 12 through the inclined mounting part 31, the inclined mounting part 31 and the connecting groove 12 can provide inclined support for the connecting shell 2, so as to press the connecting shell 2 tightly against the heating space 11 on the bottom surface of the cup body 1, and counteract the outward force of the conductive element 5 on the connecting shell 2, thereby ensuring that the connecting shell 2 can press the conductive element 5 tightly against the heating element 4, and improve the contact stability between the conductive element 5 and the heating element 4.

[0034] As an optional embodiment, to facilitate the insertion of the inclined mounting portion 31 of the assembly 3 into the connecting groove 12, such as... Figure 6As shown, the connecting groove 12 has an assembly slot 13 and a pressing groove 14. The pressing groove 14 extends horizontally on the inner side of the heating space 11, and the assembly slot 13 is arranged at an angle relative to the pressing groove 14. During assembly, the inclined mounting part 31 of the fitting 3 can be inserted into the assembly slot 13, and then the inclined mounting part 31 can be slid from the assembly slot 13 into the pressing groove 14, so that a tenon and mortise structure is formed between the fitting 3 and the inner side of the heating space 11. This facilitates the assembly between the fitting 3 and the connecting groove 12, and further ensures that the connecting groove 12 can provide support for the connection through the inclined mounting part 31, thus ensuring the stability of the connecting shell 2 in the heating space 11.

[0035] Furthermore, it should be noted that the assembly 3 can be integrally formed with the connecting shell 2, or it can be separately connected to the connecting shell 2, depending on the actual needs of the design. When the assembly 3 is integrally formed with the connecting shell 2, the assembly 3 can be an inclined protrusion (not shown in the figure) formed on the outer side of the connecting shell 2, so as to complete the assembly of the connecting shell 2 in the heating space 11 by using the cooperation between the inclined protrusion and the connecting groove 12.

[0036] When the assembly 3 is separately connected to the connecting shell 2, the assembly 3 is a ring structure that abuts against the connecting shell 2, and the inclined mounting part 31 is a ring structure that is inclined connecting piece away from the connecting shell 2, so that the connecting shell 2 can be assembled in the heating space 11 by using the cooperation of the inclined connecting piece and the connecting groove 12.

[0037] As an optional embodiment, when the assembly 3 is separately connected to the connecting shell 2, such as Figure 2 , Figure 4 and Figure 7 As shown, the side of the connecting shell 2 facing away from the heating element 4 has a pressing surface 21. The side of the mounting part 3 facing away from the inclined mounting part 31 is pressed against the pressing surface 21. By pressing the mounting part 3 against the pressing surface 21, the mounting part 3 can provide a clamping force to the connecting shell 2, thereby ensuring that the connecting shell 2 can press the conductive element 5 against the heating element 4, and further ensuring stable contact between the conductive element 5 and the heating element 4.

[0038] Furthermore, such as Figure 4 and Figure 7 As shown, a pressing step 22 is formed on the outer peripheral surface of the connecting shell 2. The pressing surface 21 is the step surface of the pressing step 22 that is away from the heating element 4, so that the pressing surface 21 can be close to the location of the heating element 4. Thus, when the assembly 3 presses the pressing surface 21, the overall thickness of the assembly 3 and the connecting shell 2 can be reduced, the space utilization rate of the assembly structure composed of the assembly 3 and the connecting shell 2 in the heating space 11 can be improved, and the overall volume of the heating space 11 can be avoided by adding the assembly 3.

[0039] It should be noted that the pressure surface 21 can also be the top surface of the connecting shell 2.

[0040] In this embodiment, as Figures 1 to 3 , Figure 9 As shown, the vacuum cup also includes a bottom cover 6, which is connected to the bottom of the cup body 1 and is connected to the connecting shell 2. The bottom cover 6 and the connecting shell 2 enclose a driving cavity 61, so that a PCB board or other driving board structure can be arranged in the driving cavity 61, and the driving board can be electrically connected to the conductive component 5. This allows the driving circuit composed of the components integrated on the driving board to energize the conductive component 5, thereby realizing the heating function of the heating element 4. The connecting shell 2 is made of heat-insulating material, which can separate the driving cavity 61 from the heating space 11, preventing the heat generated by the heating element 4 from affecting the operation of the driving structure.

[0041] Among them, such as Figure 4 and Figure 9 As shown, a pressing protrusion 62 is formed on the inner side of the bottom cover 6. The pressing protrusion 62 abuts against the side of the connecting shell 2 and the fitting 3, so as to further ensure the pressing force of the fitting 3 on the connecting shell 2 by using the pressing force of the pressing protrusion 62 on the fitting 3, and further ensure that the connecting shell 2 can press the conductive element 5 into the heating element 4, and ensure the contact between the conductive element 5 and the heating element 4.

[0042] As an optional embodiment, such as Figure 9 As shown, the bottom cover 6 has an insert groove 63, and the bottom of the cup body 1 has a connecting protrusion 15. The insert groove 63 is fitted into the connecting protrusion 15. Both the bottom cover 6 and the connecting shell 2 have connecting protrusions 64, and mounting holes are formed in the connecting protrusions 64. The bottom cover 6 and the connecting shell 2 are detachably connected through the mounting holes. Therefore, when assembling the bottom cover 6, the insert groove 63 and the connecting protrusion 15 can be used as positioning structures for the bottom cover 6, and the mounting holes of the connecting protrusions 64 can be used to improve the ease of assembling the bottom cover 6 into the cup body 1.

[0043] Among them, such as Figure 2 and Figure 9 As shown, the connecting protrusion 64 is a threaded post coaxial between the bottom cover 6 and the connecting shell 2, and the mounting hole of the bottom cover 6 is a threaded through hole, while the mounting hole of the connecting shell 2 is a threaded countersunk hole, so that the bottom cover 6 and the connecting shell 2 can be threadedly connected by bolts or studs.

[0044] In this embodiment, as Figure 7 and Figure 8As shown, the connecting shell 2 is made of insulating material to prevent short circuits in the conductive component 5, which would affect the safety performance of the cup body 1. The connecting shell 2 has a first connecting portion 23, and the conductive component 5 has a second connecting portion 53. The first connecting portion 23 and the second connecting portion 53 are detachably connected. The first connecting portion 23 is a through hole formed in the connecting shell 2, and the second connecting portion 53 is a through hole formed in the connecting surface 51 of the conductive component 5, so that the conductive component 5 and the connecting shell 2 can be connected by bolts or studs to ensure the connection stability between the conductive component 5 and the connecting shell 2.

[0045] In this embodiment, as Figure 8 As shown, the conductive component 5 has a power receiving end 54, and the connecting shell 2 has a clearance groove 24 on the side facing the conductive component 5, and the clearance groove 24 faces the power receiving end 54. The power receiving end 54 can be electrically connected to an external circuit through a wire. The protective sleeve on the outer surface of the wire can be arranged in the clearance groove 24 to organize the wire arrangement of the conductive component 5, prevent the wires from being piled up messily, and avoid the wires connected to the conductive component 5 from contacting the heating element 4 and causing a short circuit.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
