Description

Technical Field

[0001] This utility model belongs to the field of thermos cup technology, specifically relating to a vacuum thermos cup. Background Technology

[0002] Vacuum insulated cups are generally water containers made of stainless steel with a vacuum layer. They are constructed with double layers of stainless steel, and the inner liner and outer shell are joined together using welding technology. Then, vacuum technology is used to remove the air from the space between the inner liner and the outer shell. The top is equipped with a tightly sealed lid. With increasing health awareness, people have placed higher demands on the safety of drinking water and the practicality of insulated cups. Although insulated cups on the market can meet basic heat preservation needs, there are still many pain points in structural design and functional implementation.

[0003] Problems with existing technology:

[0004] On the one hand, most existing vacuum insulated cups adopt a fixed structure where the inner liner and the outer cup body are integrated. This design means that if the inner liner is damaged by bumps or if scale builds up on the inner wall and is difficult to clean thoroughly, it cannot be disassembled and replaced separately. Users can only choose to replace the entire insulated cup, which not only significantly increases the cost of use, but also causes unnecessary waste of resources.

[0005] On the other hand, in thermos cups with sterilization functions, since the main body is mostly made of stainless steel, the sterilization elements such as ultraviolet rays are usually only installed in the lid due to material limitations. This layout means that the sterilization light can only cover the mouth of the cup and a limited area nearby, making it difficult to effectively irradiate key parts such as the inside of the cup body and the bottom of the inner liner. This results in a limited sterilization range and insufficient sterilization, which cannot fundamentally guarantee drinking water hygiene and seriously affects the actual sterilization effect. Utility Model Content

[0006] The purpose of this utility model is to provide a vacuum insulated cup that adopts a modular design, consisting of multiple independent components such as an outer cup body, an inner liner, a sealing base, and a cup lid. Each component is precisely assembled to achieve overall connection. This structural design allows for direct disassembly and replacement of damaged individual components without the need for complete replacement, significantly reducing maintenance costs and greatly improving the product's durability and overall practicality.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A vacuum insulated cup includes an outer cup body, which is a tube with openings at both the top and bottom. The top of the outer cup body is provided with a concentrically bent limiting lip. The inner liner is provided inside the outer cup body, and the top opening of the inner liner extends to the outside of the outer cup body. A cavity is formed between the inner side of the outer cup body and the outer wall of the inner liner. The outer wall of the inner liner is provided with a mating groove that mates with the limiting lip. A sealing base is screwed to the bottom of the outer cup body. Multiple ultraviolet lamps are vertically arranged on the inner wall of the outer cup body through a snap-fit ​​assembly for disinfecting the drinking water inside the inner liner.

[0009] The outer cup body is made of stainless steel, and the inner liner is made of transparent glass.

[0010] The buckle assembly includes multiple inverted L-shaped plates arranged in a circumferential array on the inner wall of the outer cup. A through hole is provided on one side of the vertical plate of the inverted L-shaped plate. A limiting annular groove is provided inside the through hole. A ball is provided inside the limiting annular groove. A plug plate is provided on the top of the ultraviolet lamp strip and is inserted into the limiting groove formed by the inverted L-shaped plate and the inner wall of the outer cup.

[0011] A positioning sleeve is fixed inside the outer cup body and directly below the inverted L-shaped plate. The ultraviolet lamp strip passes through the inside of the positioning sleeve, and a transparent rubber is provided on the inner side of the positioning sleeve that contacts the outer wall of the ultraviolet lamp strip.

[0012] The bottom of the ultraviolet lamp strip is provided with two elastic conductive contacts that are connected to its positive and negative poles. The protrusions on the elastic conductive contacts are staggered vertically. The outer wall of the sealed base is provided with two conductive rings that cooperate with the elastic conductive contacts.

[0013] A battery is installed at the bottom of the sealed base. A mechanical timer switch is installed at the bottom of the sealed base and on the side of the battery. A push-button switch is installed at the bottom of the sealed base and on the side of the mechanical timer switch. The battery, push-button switch, mechanical timer switch and conductive ring are connected in series.

[0014] The bottom of the sealing base is provided with an air extraction hole, and a vacuum one-way valve is provided inside the air extraction hole.

[0015] A sealing ring is provided between the limiting lip and the mating groove, and the cross-section of the sealing ring is L-shaped.

[0016] The inner side of the outer cup body has multiple buffer pads arranged equidistantly along the circumferential direction, and the other side of the buffer pads is in contact with the outer wall of the inner liner.

[0017] The technical effects achieved by this utility model are as follows:

[0018] This utility model consists of multiple components, including an outer cup body, an inner liner, a sealing base, and a cup lid. It adopts a modular design, with each component assembled independently, facilitating maintenance and replacement, reducing maintenance costs, and improving the overall practicality of the product. The outer cup body is a stainless steel tube with openings at both the top and bottom, which not only improves the strength of the thermos but also effectively blocks ultraviolet rays from shining outward. The inner liner is made of transparent glass, allowing ultraviolet rays to pass through smoothly to disinfect the drinking water inside, and its top opening extends to the outside of the outer cup body for easy water retrieval. A vacuum is created in the cavity formed by the outer cup body and the inner liner through a vent, enhancing the heat preservation effect.

[0019] This invention features an equidistant array of ultraviolet lamps arranged on the inner wall of the outer cup, allowing ultraviolet light to irradiate from the side of the inner liner. This layout breaks away from the limitations of traditional disinfection elements that are confined to the cup lid, enabling ultraviolet light to cover all areas inside the inner liner, including the inner side of the cup body and the bottom, thus providing comprehensive and thorough disinfection of drinking water and significantly improving the sterilization effect. In addition, the ultraviolet lamps can be easily disassembled and installed using a specially designed snap-fit ​​assembly, facilitating future replacement and maintenance and further reducing maintenance costs.

[0020] When using the ultraviolet lamp strip, this utility model allows users to turn on the button switch and then rotate the knob of the mechanical timer switch to set the sterilization time as needed. It can also use the characteristics of the mechanical timer switch to remind users to drink water at set times, just like the mechanical timer switch on a microwave oven. When the time is up, it will make an audible reminder to the user, increasing the practicality of the device. Attached Figure Description

[0028] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0029] like Figures 1-3 As shown, a vacuum insulated cup includes an outer cup body 1, which is a tube with openings at both the top and bottom. The top of the outer cup body 1 is provided with a concentrically bent limiting lip 2. The outer cup body 1 is provided with a removable inner liner 3, and the top opening of the inner liner 3 extends to the outside of the outer cup body 1. A cavity is formed between the inner side of the outer cup body 1 and the outer wall of the inner liner 3. The outer wall of the inner liner 3 is provided with a mating groove 4 that mates with the limiting lip 2. The bottom of the outer cup body 1 is sealed with a sealing base 7. The top of the sealing base 7 is provided with a rubber pad that contacts the inner liner 3. The inner wall of the outer cup body 1 is vertically provided with multiple ultraviolet lamp strips 11 through a buckle assembly for disinfecting the drinking water in the inner liner 3. The outer wall of the limiting lip 2 is threaded with a cup lid 8 that seals the inner liner 3.

[0030] The outer cup body 1 is made of stainless steel, and the inner liner 3 is made of transparent glass;

[0031] A sealing ring 6 is provided between the limiting lip 2 and the mating groove 4, and the cross section of the sealing ring 6 is L-shaped; multiple buffer pads 5 are equidistantly arranged along the circumferential direction on the inner side of the outer cup body 1, and the other side of the buffer pad 5 is in contact with the outer wall of the inner liner 3.

[0032] According to the above structure, the mutual cooperation of the limiting lip 2 and the mating groove 4 can limit the inner liner 3. By tightening the sealing base 7, the inner liner 3 can be stably fixed inside the outer cup body 1. The structure is simple and easy to operate, making it convenient to install and disassemble the inner liner 3, and also convenient to replace the inner liner 3. The ultraviolet lamp strip 11 is set vertically on the inner wall of the outer cup body 1, and its height covers the entire water-filling part of the inner liner 3, which is convenient for ultraviolet disinfection of the drinking water in the inner liner 3. The outer cup body 1 is made of stainless steel, which improves the strength of the thermos cup and also prevents ultraviolet rays from passing through the outer cup body 1 and shining outward. The inner liner 3 is made of transparent glass, which allows ultraviolet rays to pass through the inner liner 3 smoothly for disinfection, increasing the completeness and practicality of the equipment. The sealing ring 6, rubber gasket and buffer pad 5 can effectively protect the inner liner 3, increasing the practicality of the equipment. The modular design of this structure facilitates the maintenance and replacement of each component.

[0033] like Figures 2-5 As shown, the buckle assembly includes a plurality of inverted L-shaped plates 15 arranged in a circumferential array on the inner wall of the outer cup body 1. A through hole 16 is provided on one side of the vertical plate of the inverted L-shaped plate 15. A limiting annular groove 18 is provided inside the through hole 16. A ball block 17 is provided inside the limiting annular groove 18. A plug plate 19 is provided on the top of the ultraviolet lamp strip 11, and the plug plate 19 is inserted into the limiting groove formed by the inverted L-shaped plate 15 and the inner wall of the outer cup body 1.

[0034] A positioning sleeve 21 is fixed inside the outer cup body 1 and directly below the inverted L-shaped plate 15. The ultraviolet lamp strip 11 passes through the inside of the positioning sleeve 21, and a transparent rubber is provided on the inner side of the positioning sleeve 21 that contacts the outer wall of the ultraviolet lamp strip 11.

[0035] According to the above structure, when installing the ultraviolet lamp strip 11, the top of the ultraviolet lamp strip 11 passes through the positioning sleeve 21 until the top plug plate 19 is inserted into the limiting groove formed by the inner wall of the outer cup body 1 and the inverted L-shaped plate 15. At this time, the ball block 17 is aligned with the slot 20. Then the inner liner 3 is installed. The outer wall of the inner liner 3 squeezes the ball block 17, causing the other side of the ball block 17 to be inserted into the slot 20, thus fixing the ultraviolet lamp strip 11. The positioning sleeve 21 is convenient for positioning the installation of the ultraviolet lamp strip 11 and is quite practical. The transparent rubber, through its properties, provides initial fixation for the ultraviolet lamp strip 11, making the fixation fluid of the ultraviolet lamp strip 11 relatively stable.

[0036] like Figures 2-4 As shown, the bottom of the ultraviolet lamp strip 11 is provided with two elastic conductive contacts 12 connected to its positive and negative poles. The protrusions on the elastic conductive contacts 12 are staggered vertically. The outer wall of the sealing base 7 is provided with two conductive rings 10 that cooperate with the elastic conductive contacts 12.

[0037] A battery 9 is installed at the bottom of the sealed base 7. A mechanical timer switch 13 is installed at the bottom of the sealed base 7 and on one side of the battery 9. A push-button switch 14 is installed at the bottom of the sealed base 7 and on one side of the mechanical timer switch 13. The battery 9 is connected in series with the push-button switch 14, the mechanical timer switch 13 and the conductive ring 10.

[0038] Based on the above structure, when using the ultraviolet lamp strip 11, turn on the button switch 14, and rotate the knob of the mechanical timer switch 13 to set the sterilization time as needed. It can also remind the user to drink water at set times based on the characteristics of the mechanical timer switch 13, just like the mechanical timer switch 13 on the microwave oven currently in use. When the time is up, it will make an audible reminder to the user, which increases the practicality of the equipment.

[0039] like Figures 2-3 As shown, the bottom of the sealing base 7 is provided with an air extraction hole 22, and a vacuum check valve is provided inside the air extraction hole 22.

[0040] According to the above structure, after the thermos cup is assembled, a vacuum is drawn through the air extraction hole 22 to form the cavity between the outer cup body 1 and the inner liner 3.

[0041] The working principle of this utility model is as follows: the inner liner 3 is placed inside the outer cup body 1, so that the mating groove 4 on the outer wall of the inner liner 3 is aligned and nested with the limiting lip 2 on the top of the outer cup body 1. At this time, the L-shaped sealing ring 6 achieves a preliminary seal. Then, the sealing base 7 is screwed tightly onto the bottom of the outer cup body 1, and the rubber pad on its top presses upward against the bottom of the inner liner 3, forming an upper and lower clamping force with the limiting lip 2. With the help of the circumferential array of buffer pads 5, the inner liner 3 is stably fixed. The buffer pads 5 can absorb radial impact force, while the rubber pads buffer axial vibration. The double protection ensures that the inner liner 3 is not easily damaged during movement.

[0042] The ultraviolet light strip 11 is fixed to the inner wall of the outer cup body 1 by a snap-fit ​​assembly. During installation, the plug plate 19 is inserted into the limiting groove formed by the inverted L-shaped plate 15 and the outer cup body 1. The positioning sleeve 21 ensures the verticality of the light strip. After the inner liner 3 is installed, the squeezing ball block 17 is inserted into the slot 20 to complete the fixing of the light strip. When disinfection is required, the button switch 14 is pressed and the mechanical timer switch 13 is rotated to set the duration. The battery 9 supplies power to the ultraviolet light strip 11 through the contact between the conductive ring 10 and the elastic conductive contact 12. Since the inner liner 3 is made of transparent glass, ultraviolet rays can penetrate the inner liner 3 to irradiate the drinking water, while the stainless steel outer cup body 1 blocks the ultraviolet rays from leaking out. The staggered protrusion design of the elastic conductive contact 12 ensures that there is no risk of short circuit between the positive and negative poles, improving circuit safety.

[0043] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
