Description

Technical Field

[0001] This utility model relates to the field of titanium cup technology, specifically to a leak-proof structure for a lead-free glass-sealed titanium cup. Background Technology

[0002] A titanium cup is a cup made of titanium metal. It took over a century from the discovery of titanium to the production of pure titanium. However, its true utilization and understanding of its properties only began after the 1940s. Titanium has excellent heat resistance, with a melting point as high as 1668℃. At room temperature, titanium can remain unharmed in solutions of various strong acids and alkalis. Even the most potent acid—aqua regia—cannot corrode it. Titanium is resistant to seawater; someone once submerged a piece of titanium on the seabed, and five years later, when it was retrieved, it was covered with small animals and seaweed, yet it showed no signs of rust and remained shiny.

[0003] Currently, lead-free glass titanium insulated cups on the market generally suffer from the technical problem of reduced heat preservation performance. Due to the lack of effective means of locating and detecting leaks, when the vacuum layer of the product fails, consumers often have no choice but to passively accept the reality of reduced heat preservation. This irreparable defect forces users to frequently replace insulated containers, which not only wastes resources and increases the economic burden on consumers, but also goes against the concept of sustainable development and environmental protection. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: An airtight structure for a lead-free glass-sealed titanium cup includes a container mechanism and a detection mechanism. The container mechanism includes an inner liner, a cup sleeve fitted onto the outside of the inner liner, a handle connected to the outer wall of the cup sleeve, and a screw cap screwed onto the top of the inner liner. The detection mechanism includes a heat-insulating cavity formed between the inner liner and the cup sleeve, a rubber stopper slidably installed inside the handle, a push rod connected to the outer end of the rubber stopper, and an arc surface disposed on the inner edge of the top of the cup sleeve.

[0006] By adopting the above technical solution, once the holder feels that the heat preservation time and effect have decreased, the holder can add a small amount of water to the curved surface, then squeeze the push rod inside the cup sleeve, and then the rubber stopper will squeeze the air in the heat preservation cavity. The air will rise along the outer wall of the inner liner and then overflow from the leaking point at the top of the cup sleeve. The overflow phenomenon is specifically manifested as water bubbles coming out of the leaking point. After the holder finds the leaking point, they can repair it in a targeted manner to avoid wasting resources, which is in line with the environmental protection concept of sustainable development.

[0007] In a preferred embodiment, the present invention can be further configured such that: the bottom of the handle has an insertion port communicating with the interior of the insulation cavity, and the rubber plug and the push rod are both movably disposed inside the insertion port.

[0008] In a preferred embodiment, the present invention can be further configured such that: a sealing ring is fitted onto the outer side of the inner liner, and the top of the sealing ring fits against the top of the inner cavity of the cup sleeve.

[0009] In a preferred embodiment, the present invention can be further configured such that: a heat-insulating component is fixedly connected to the inner wall of the cup sleeve, the heat-insulating component is movably sleeved on the outer side of the inner liner, and the sealing ring is interference-fitted to the top of the heat-insulating component.

[0010] In a preferred embodiment, the present invention can be further configured such that the insulation component is processed into a hollow column shape, and the inner wall of the hollow column is processed into a corrugated surface.

[0011] In a preferred embodiment, the present invention can be further configured such that: a reinforcing component is provided at the bottom of the inner liner, the reinforcing component being composed of a round cover and multiple fitting blocks, the multiple fitting blocks being arranged around the outside of the round cover and integrally formed with the round cover.

[0012] In a preferred embodiment, the present invention can be further configured such that: the round cover is fitted onto the bottom of the inner liner, the fitting block is set as a triangle, and the outer wall of the fitting block is fixedly connected to the inner wall of the hollow column.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, once the holder feels that the heat preservation time and heat preservation effect have decreased, the holder can add a small amount of water to the curved surface, and then squeeze the push rod into the cup sleeve. Then the rubber stopper will squeeze the air in the heat preservation cavity. The air will rise along the outer wall of the inner liner and then overflow from the leaking position at the top of the cup sleeve. The overflow phenomenon is specifically manifested as water bubbles coming out of the leaking position. After the holder finds the leaking position, he / she can repair it in a targeted manner to avoid wasting resources, which is in line with the environmental protection concept of sustainable development.

[0014] 2. In this utility model, the round cap and the fitting block work together to effectively strengthen the hollow column and the cup sleeve after supporting the inner wall of the hollow column. The round cap also improves the installation firmness of the inner liner. With the combination of these two effects, the service life of this product is improved. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0018] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0019] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an air-leakage-proof structure for a lead-free glass-sealed titanium cup.

[0020] Example 1: Combination Figure 1-5 As shown, the present invention provides a leak-proof structure for a lead-free glass sealed titanium cup, including a container mechanism 100 and a detection mechanism 200. The container mechanism 100 includes an inner liner 110, a cup sleeve 120 sleeved on the outside of the inner liner 110, a handle 130 connected to the outer wall of the cup sleeve 120, and a screw cap 140 screwed to the top of the inner liner 110. The testing mechanism 200 includes a heat-insulating cavity 210 formed between the inner liner 110 and the cup sleeve 120, a rubber stopper 220 slidably installed inside the handle 130, a push rod 230 connected to the outer end of the rubber stopper 220, and an arc surface 240 disposed on the inner edge of the top of the cup sleeve 120.

[0021] Furthermore, the bottom of the handle 130 is provided with an insertion port that communicates with the interior of the insulation cavity 210. The rubber plug 220 and the push rod 230 are both movably disposed inside the insertion port. The insertion port provides installation conditions for the rubber plug 220 and the push rod 230, and also ensures that the air leakage detection operation can be carried out smoothly.

[0022] Furthermore, a sealing ring 300 is fitted onto the outer side of the inner liner 110, and the top of the sealing ring 300 fits against the top of the inner cavity of the cup sleeve 120. The sealing ring 300 can improve the sealing performance between the inner liner 110 and the cup sleeve 120.

[0023] Example 2: Combination Figure 4 and Figure 5 As shown, based on Embodiment 1, a heat-insulating component 400 is fixedly connected to the inner wall of the cup sleeve 120. The heat-insulating component 400 is movably sleeved on the outside of the inner liner 110. The sealing ring 300 is interference-fitted to the top of the heat-insulating component 400. The heat-insulating component 400 can improve the heat preservation function of the inner liner 110.

[0024] Furthermore, the insulation component 400 is processed into a hollow column 410, and the inner wall of the hollow column 410 is processed into a corrugated surface 420. The shape design of the corrugated surface 420 can increase the heat reflective surface and further improve the insulation function.

[0025] Example 3: Combination Figure 4 and Figure 5 As shown in the above embodiment, the bottom of the inner liner 110 is provided with a reinforcing component 500. The reinforcing component 500 consists of a round cover 510 and a plurality of mating blocks 520. The plurality of mating blocks 520 are arranged around the outside of the round cover 510 and are integrally formed with the round cover 510. The round cover 510 and the mating blocks 520 cooperate to support the interior of the hollow column 410, reduce the probability of deformation of the hollow column 410 and the cup sleeve 120, and at the same time improve the installation firmness of the inner liner 110.

[0026] Furthermore, the round cover 510 is fitted onto the bottom of the inner liner 110, and the fitting block 520 is set as a triangle. The outer wall of the fitting block 520 is fixed to the inner wall of the hollow column 410. The shape design of the fitting block 520 can better fit the corrugated surface 420, ensuring that the round cover 510 can be firmly suspended inside the hollow column 410.

[0027] The working principle and usage process of this utility model: During the use of this product, if the user feels that the heat preservation time or heat preservation effect has decreased, the user can add a small amount of water at the arc surface 240 position, and then squeeze the push rod 230 into the cup sleeve 120. Then the rubber stopper 220 squeezes the air in the heat preservation cavity 210. The air rises along the outer wall of the inner liner 110, passes through the sealing ring 300, and overflows from the air leakage position at the top of the cup sleeve 120. The overflow phenomenon is specifically manifested as water bubbles coming out of the air leakage position. After the user finds the air leakage position, they can repair it accordingly.

[0028] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
