Description

Technical Field

[0001] The utility model relates to the field of water cups, and more specifically, to a vacuum pumping structure and a cup body. Background Art

[0002] Thermos cups are usually made of ceramic or stainless steel, with a vacuum layer inside and a tightly sealed lid on top for holding water or other liquids. The design of the vacuum insulation layer allows the thermos to maintain the temperature of both hot and warm water for a long time, avoiding the trouble of frequently changing hot water or waiting for hot water to cool down. The strong portability makes the thermos very suitable for carrying. Whether it is placed in a bag or pocket, you can enjoy hot water anytime and anywhere. It is especially suitable for outdoor activities, office work or daily life. Material safety is also a major advantage of thermos cups. They are usually made of materials such as stainless steel or glass, which have good corrosion resistance and high temperature resistance, ensuring safe and reliable use. The easy-to-clean design means that the lid and inner wall of the thermos cup are usually sealed, which is convenient for cleaning and disinfection to maintain hygiene.

[0003] In existing vacuum insulation cups, the pores of the vacuum flask need to be sealed by melting the flux after the vacuum is completed, which will cause the following problems:

[0004] ① When the vacuum solder melts, it tends to drip into the vacuum cavity. After solidification, it forms a long drop-shaped structure. When shaken during use, it is easy to break and enter the vacuum layer (the layer between the inner and outer walls), causing "cup ringing";

[0005] ② When the vacuum degree is not enough after evacuation, re-evacuation is performed to remove the blocked vacuum solder, and its fragments are likely to fall into the vacuum layer, causing "ringing cup". Utility Model Content

[0006] The present invention aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provide a vacuum pumping structure and a cup body for solving the problem of "cup ringing".

[0007] The technical solution adopted by the present invention is to provide a vacuum pumping structure, including: an inner wall and an outer wall, the inner wall and the outer wall are connected to form an interlayer cavity between the inner wall and the outer wall, and also including: an exhaust structure, the exhaust structure is connected to the interlayer cavity, and is used to vacuum the interlayer cavity so that a vacuum layer is formed in the interlayer cavity; the exhaust structure includes: an exhaust part provided with an exhaust port, and a supporting component arranged on one side of the exhaust port, an air-guiding gap is left between the supporting component and the exhaust port, and the supporting component is used to receive the sealing material entering the exhaust port.

[0008] In the present technical solution, by setting a supporting component, whether during the assembly process of the vacuum structure or after assembly when it is found that the vacuum degree is insufficient and the sealing material needs to be melted again, the sealing material can be effectively prevented from forming a pointed cone shape in the interlayer cavity during the melting process, thereby reducing the formation of an easily fractured structure of the sealing material, and at the same time, it can prevent particles from entering the interlayer cavity when the sealing material breaks, thereby preventing the generation of abnormal noise.

[0009] Furthermore, the exhaust portion is provided on the inner wall and is formed by a recess of the inner wall, and / or the exhaust portion is provided on the outer wall and is formed by a recess of the outer wall.

[0010] In this technical solution, the recess is used to provide a space for the sealing material, facilitating the fixing of the sealing material on the vacuum structure. At the same time, the recess increases the space for the sealing material, allowing more sealing material to be used to seal the exhaust port, thereby improving the sealing performance and preventing the insulation effect from being affected by insufficient vacuum due to air leakage. In addition, the recess is directly formed through the inner or outer wall without the need for additional structure, making the overall structure simple, saving production material costs, simplifying the preparation process, and reducing the weight of the vacuum structure itself, facilitating transportation, and making it more portable for users.

[0011] Furthermore, the exhaust portion is an annular depression, and the annular depression is recessed toward one side of the interlayer cavity.

[0012] In the present technical solution, compared with the square depression, the annular depression will not produce corners. When the sealing material needs to be re-melted, it can prevent the sealing material at the corners from being wasted due to the existence of corners, thereby improving the utilization rate of the sealing material; the depression is concave into the interlayer cavity to facilitate the fixation of the sealing material.

[0013] Furthermore, the supporting assembly includes a supporting tray, which includes a tray body and a connecting arm. The tray body is connected to the inner side of the interlayer cavity through the connecting arm. A gap is left between the tray body and the exhaust part to form an air-guiding gap connected to the interlayer cavity.

[0014] In this technical solution, when the sealing material melts and drips into the interlayer cavity through the exhaust port, the disc body blocks the formation of a pointed cone, thus preventing the conical sealing material from breaking and causing unusual noises. The disc body is connected to the inner side of the interlayer cavity via a link arm, which increases the contact area between the support tray and the interlayer cavity, making it more secure. The provision of an air-guiding gap ensures that the placement of the disc body does not affect vacuum extraction. The disc body is preferably positioned directly opposite the exhaust port.

[0015] Furthermore, the disc body includes a receiving cavity and a surrounding edge surrounding the receiving cavity; the middle portion of the disc body is recessed toward a side away from the exhaust port to form the receiving cavity; and the cross-section of the receiving cavity is larger than that of the exhaust port.

[0016] In this technical solution, the opening of the receiving cavity is retracted inward by the design of the surrounding edge, making it difficult for sealing material dripping into the receiving cavity to overflow. The receiving cavity formed by the central portion of the disc body being recessed toward the side away from the exhaust port can increase the capacity of the receiving cavity, so that even when a large amount of sealing material drips from the exhaust port, it can still be received and prevented from falling into the interlayer cavity. The cross-section of the receiving cavity is larger than the cross-section of the exhaust port, ensuring that the size of the receiving cavity can cover the exhaust port, thereby facilitating the sealing material dripping from the exhaust port to fall into the receiving cavity.

[0017] Furthermore, the supporting assembly includes a porous supporting sheet, which is connected to the inner side of the interlayer cavity to form a non-sealed cover on the exhaust portion; the exhaust port is connected to the interlayer cavity through the porous supporting sheet.

[0018] In this technical solution, when the sealing material drips through the vent, it is blocked by the porous support sheet and does not form a sharp cone. Instead, it adheres to the porous support sheet, preventing the sharp cone-shaped sealing material from breaking and causing abnormal noise in the interlayer cavity. The vent is connected to the interlayer cavity through the porous support sheet, ensuring smooth vacuum operation.

[0019] Furthermore, the porous supporting sheet is a metal mesh, the wire diameter of the porous supporting sheet is less than 0.3 mm, and the mesh size of the porous supporting sheet is 100 to 200.

[0020] In this technical solution, the wire diameter and mesh number of the porous support sheet are limited to prevent the molten sealing material from passing through the support sheet and dripping directly into the interlayer cavity due to the wire diameter being too large, thereby causing abnormal noise. At the same time, it can also ensure smooth communication between the interlayer cavity and the exhaust port.

[0021] Furthermore, the supporting assembly includes a supporting tray and a porous supporting sheet; the porous supporting sheet is connected to the inner wall of the interlayer cavity and is arranged between the supporting tray and the exhaust part; the supporting tray is connected to the inner wall of the interlayer cavity through the porous supporting sheet.

[0022] In this technical solution, the porous support sheet serves as the first layer of supporting component. When the molten sealing material drips through the exhaust port, it first reaches the porous support sheet. When too much sealing material drips, part of it passes through the porous support sheet and drips onto the second layer of supporting component, i.e., the support tray. This forms a double protection to prevent the molten sealing material from dripping into the interlayer cavity.

[0023] Another object of the present invention is to provide a cup body, comprising any one of the above-mentioned vacuum structures, wherein a partition wall is provided inside the vacuum structure to separate the vacuum structure into a liquid containing cavity and a functional containing cavity.

[0024] In this technical solution, the liquid cavity is used to contain liquid; and the functional cavity is used to contain functional components.

[0025] Furthermore, the exhaust structure is provided on the inner wall and is located in the functional cavity.

[0026] In this technical solution, the exhaust structure is arranged on the inner wall without affecting the appearance of the vacuum structure, making it more beautiful and improving user acceptance. The exhaust structure is arranged in the functional cavity to prevent the sealing material from contaminating the liquid in the liquid cavity.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] (1) The present invention provides a supporting assembly. Whether during the assembly process of the vacuum structure or after assembly when the vacuum degree is insufficient and the sealing material needs to be melted again, the sealing material can be effectively prevented from forming a pointed cone shape in the interlayer cavity during the melting process, thereby reducing the formation of a structure that is easy to break by the sealing material. At the same time, it can prevent particles from entering the interlayer cavity when the sealing material breaks, thereby preventing the generation of abnormal noise.

[0029] (2) The present invention adds a porous support sheet as the first layer of support component. When the molten sealing material drips through the exhaust port, it first reaches the porous support sheet. When too much sealing material drips, part of it passes through the porous support sheet and drips onto the second layer of support component, i.e., the support tray. This forms a double protection to prevent the molten sealing material from dripping into the interlayer cavity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The drawings in this utility model are for illustrative purposes only and are not to be construed as limiting the scope of this utility model. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the products. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted from the drawings.

[0038] Example 1

[0039] refer to Figure 1 and Figure 2 This embodiment provides a vacuum pumping structure, comprising: an inner wall 100 and an outer wall 200, the inner wall 100 and the outer wall 200 being connected to form an interlayer cavity 110 therebetween; and an exhaust structure communicating with the interlayer cavity 110 and configured to evacuate the interlayer cavity 110 to form a vacuum layer therein. The exhaust structure comprises: an exhaust portion 300 having an exhaust port 310, and a supporting assembly disposed on one side of the exhaust port 310, with an air-guiding gap 320 being provided between the supporting assembly and the exhaust port 310. The supporting assembly is configured to receive a sealing material that enters the exhaust port 310. The sealing material may be flux, such as glass beads.

[0040] By setting up a supporting component, whether during the assembly process of the vacuum structure or after assembly when it is found that the vacuum degree is insufficient and the sealing material needs to be melted again, the sealing material can be effectively prevented from forming a pointed cone shape in the interlayer cavity 110 during the melting process, thereby reducing the formation of an easily fractured structure of the sealing material. At the same time, it can prevent particles from entering the interlayer cavity 110 when the sealing material breaks, thereby preventing the generation of abnormal noise.

[0041] Preferably, the vent portion 300 is provided on the inner wall 100 and formed by a recess in the inner wall 100, and / or the vent portion 300 is provided on the outer wall 200 and formed by a recess in the outer wall 200. For example, the vent portion 300 may not be provided on the inner wall 100 and formed by a recess in the inner wall 100; or the vent portion 300 may be provided on the outer wall 200 and formed by a recess in the outer wall 200; or a combination of the above two solutions. Furthermore, the vent portion 300 is an annular recess that is recessed toward one side of the interlayer cavity 110.

[0042] The formed depression is used to provide a holding space for the sealing material, which is convenient for fixing the sealing material on the vacuum structure. At the same time, the holding space for the sealing material is increased by the depression, and more sealing material can be used to seal the exhaust port 310, thereby improving the sealing performance and preventing the insulation effect from being affected by insufficient vacuum due to air leakage. In addition, the depression is directly formed through the inner wall 100 or the outer wall 200, without the need for additional structure, which makes the overall structure simple, saves production material costs, simplifies the preparation process, and is also beneficial to reducing the weight of the vacuum structure itself, facilitating transportation, and is more portable for users. In addition, compared with the square depression, the annular depression will not have corners. When the sealing material needs to be re-melted, it is prevented that the sealing material at the corners cannot be melted due to the existence of corners, thereby improving the utilization rate of the sealing material; the depression is concave toward the interlayer cavity 110, which facilitates the fixing of the sealing material.

[0043] Preferably, the supporting assembly includes a supporting tray 400, and the supporting tray 400 includes a tray body 410 and a connecting arm 420. The tray body 410 is connected to the inner side of the interlayer cavity 110 through the connecting arm 420. A gap is left between the tray body 410 and the exhaust part 300 to form an air-conducting gap 320 connected to the interlayer cavity 110.

[0044] When the sealing material melts and drips into the interlayer cavity 110 through the exhaust port 310, the disk body 410 blocks the formation of a pointed cone shape, thereby preventing the pointed cone-shaped sealing material from breaking and causing abnormal noise. The disk body 410 is connected to the inner side of the interlayer cavity 110 via a link arm, which can increase the contact area between the support tray 400 and the interlayer cavity 110, making it more secure. The provision of the air guide gap 320 ensures that the provision of the disk body 410 does not affect vacuum extraction. The disk body 410 is preferably positioned directly opposite the exhaust port 310.

[0045] Preferably, the disc body 410 includes a receiving cavity 411 and a surrounding edge 412 surrounding the receiving cavity 411; the middle portion of the disc body 410 is recessed toward the side away from the exhaust port 310 to form the receiving cavity 411; the cross-section of the receiving cavity 411 is larger than the exhaust port 310.

[0046] The design of the surrounding edge 412 causes the opening of the receiving cavity 411 to shrink inward, making it difficult for the sealing material dripping into the receiving cavity 411 to overflow. The receiving cavity 411 formed by the middle portion of the disc body 410 being recessed toward the side away from the exhaust port 310 can increase the capacity of the receiving cavity 411, so that even when a large amount of sealing material drips from the exhaust port 310, it can still be received and prevented from falling into the interlayer cavity 110. The cross-section of the receiving cavity 411 is larger than the cross-section of the exhaust port 310, ensuring that the size of the receiving cavity 411 can cover the exhaust port 310, thereby facilitating the sealing material dripping from the exhaust port 310 to fall into the receiving cavity 411.

[0047] Example 2

[0048] This embodiment provides a vacuum pumping structure similar in structure to that of Embodiment 1, except that the support assembly comprises only a porous support sheet 500, which is connected to the inner side of the interlayer cavity 110, forming a non-sealed cover on the exhaust portion 300; the exhaust port 310 communicates with the interlayer cavity 110 through the porous support sheet 500. The porous support sheet 500 is a metal mesh with a wire diameter less than 0.3 mm, and the mesh size is 100 to 200. Preferably, the wire diameter is 0.1 to 0.3 mm.

[0049] In this embodiment, when the sealing material drips through the exhaust port 310, it is blocked by the porous support sheet 500 and does not form a sharp cone shape. Instead, it adheres to the porous support sheet 500, preventing the sharp cone-shaped sealing material from breaking and causing abnormal noise in the interlayer cavity 110. The exhaust port is connected to the interlayer cavity 110 through the porous support sheet, ensuring smooth vacuum operation.

[0050] Example 3

[0051] refer to Figure 3 and Figure 4 This embodiment provides a vacuum pumping structure similar in structure to that of Embodiment 1, except that the support assembly includes a support tray 400 and a porous support sheet 500. The porous support sheet 500 is connected to the inner wall 100 of the interlayer cavity 110 and disposed between the support tray 400 and the exhaust portion 300. The support tray 400 is connected to the inner wall 100 of the interlayer cavity 110 via the porous support sheet 500. The porous support sheet 500 is a metal mesh with a wire diameter less than 0.3 mm and a mesh size of 100 to 200. Preferably, the wire diameter is 0.1 to 0.3 mm.

[0052] In this embodiment, the porous supporting sheet 500 serves as the first layer of supporting component. When the molten sealing material drips through the exhaust port 310, it first reaches the porous supporting sheet 500. When too much sealing material drips, part of it passes through the porous supporting sheet 500 and drips onto the second layer of supporting component, i.e., the supporting tray 400. This forms a double protection to prevent the molten sealing material from dripping into the interlayer cavity 110.

[0053] Example 4

[0054] refer to Figure 5 This embodiment provides a vacuum structure, which is similar to that of embodiment 3, except that: a convex edge 330 is provided on the edge of the exhaust portion 300, and the convex edge 330 is formed by the inner wall 100 or the outer wall 200 protruding in the direction away from the interlayer cavity 110, and the inner wall 100 of the convex edge 330 forms a capacity expansion cavity 340, and the capacity expansion cavity 340 is connected to the receiving cavity 411, thereby increasing the volume of the receiving cavity 411 and accommodating more sealing materials, further preventing the sealing materials from dripping into the interlayer cavity 110, and preventing the generation of "ringing cup".

[0055] Example 5

[0056] refer to Figure 6 This embodiment provides a cup body 600, comprising any one of the vacuum structures provided in Embodiments 1 to 4, wherein a partition wall is provided within the vacuum structure, dividing the vacuum structure into a liquid receiving chamber 610 and a functional receiving chamber 620. The liquid receiving chamber 610 is used to hold liquid; the functional receiving chamber 620 is used to hold functional components.

[0057] The exhaust structure is disposed on the inner wall 100 and is located within the functional cavity 620. Placing the exhaust structure on the inner wall 100 does not affect the appearance of the vacuum structure, making it more aesthetically pleasing and improving user acceptance. Placing the exhaust structure within the functional cavity 620 prevents contamination of the liquid within the liquid cavity 610 by the sealing material.
