[0002] A glass cup is a tea drinking utensil made of transparent glass as the main material. Compared with a thermos cup, a glass cup has better transparency and appearance.

[0003] However, since glass has excellent thermal conductivity, in practice, the outer wall of a glass into which hot water is poured is very hot and often scalds the user.

[0004] Therefore, we believe that a glass cup with a temperature insulation function is needed to avoid scalding the user. Summary of the invention

[0005] In view of the deficiencies in the prior art, the utility model proposes a glass cup with a heat insulation function, which has the advantages of temperature insulation and avoiding scalding users, and solves the disadvantage that the prior art devices are prone to scalding users.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Please refer to Figure 1-4 A glass cup with heat insulation function includes an outer shell 1. The upper part of the outer shell 1 is an open structure so that a glass cup 4 can be placed into the outer shell 1. The outer shell 1 prevents a user from directly holding the glass cup 4, thereby avoiding burns.

[0024] It should be noted that, in practice, the outer shell 1 in the present device can be produced by limiting its material and using a plastic material with slow heat conduction, which can fully ensure that the outer shell 1 can produce a heat insulation effect.

[0025] However, due to the heat conduction speed of the outer shell 1 itself, the liquid in the glass 4 cools down slowly, which makes it impossible for the user to drink boiled water at a suitable temperature in the glass 4 within the expected time.

[0026] Therefore, a plurality of slide grooves 2 are circumferentially formed on the side end surface of the outer shell 1 , and a driving rod 8 with a horizontal central axis is inserted into the slide groove 2 .

[0027] In addition, a pull rope 7 is provided between the driving rod 8 and the glass 4, and one end of the pull rope 7 is fixedly connected to the driving rod 8, so that when the user slides the driving rod 8, the glass 4 can be driven to make relative movement relative to the outer shell 1, so that the glass 4 can protrude out of the outer shell 1 and directly contact the air, and with the help of the faster gas circulation speed in the air (high-temperature air flows to low-temperature air), the glass 4 can be restored to the correct cooling speed.

[0028] Specifically, the device is provided with a follower ring 6 on the outer wall of the glass 4, and the end of the pull rope 7 away from the driving rod 8 is fixedly connected to the follower ring 6. In addition, the follower ring 6 and the glass 4 are interference fit so that the follower ring 6 can keep synchronous movement with the glass 4.

[0029] It should be noted that in practice, during the processing of the glass cup 4, several protrusions can be added to the contact part between it and the follower ring 6, and corresponding matching grooves can be set on the inner side of the follower ring 6 for the protrusions. This can further enhance the friction resistance between the glass cup 4 and the follower ring 6 to ensure that the two can move synchronously.

[0030] Furthermore, in order to avoid unbalanced force on the glass 4, multiple driving rods 8 can apply uniform tension to the glass 4 in the circumferential direction through the pull rope 7. The device is provided with a rubber insulation ring 3 on the outside of the outer shell 1. The insulation ring 3 is slidably connected to the outer shell 1, and the multiple driving rods 8 are fixedly connected to the inner wall of the insulation ring 3 at one end away from the central axis of the outer shell 1.

[0031] Similarly, the temperature-isolating ring 3 may also be made of a material with a slow heat conduction rate, such as rubber or plastic.

[0032] Furthermore, when the user holds the temperature-isolating ring 3 , the temperature-isolating ring 3 and the outer shell 1 are present between the user and the glass 4 , which can further enhance the temperature-isolating effect.

[0033] Furthermore, as shown in the figure, the device is provided with a transverse anti-slip groove 2 on the temperature-isolating ring 3, which helps the user to slide the temperature-isolating ring 3 up and down.

[0034] Furthermore, the device is fixedly connected to the inner wall of the outer shell 1 in the circumferential direction with multiple limit rods 5 whose central axes are horizontal and whose vertical planes are projected into a T-shaped structure. The multiple limit rods 5 correspond one by one to the multiple pull ropes 7, and the height of the limit rods 5 is greater than that of the driving rod 8 and the follower ring 6.

[0035] At this time, by sleeve-arranging the middle section of the pull rope 7 on the outer side of the corresponding limit rod 5, the pull rope 7 is slidably connected with the limit rod 5, so that the purpose of moving the insulation ring 3 downward to lift the glass 4 can be achieved. Compared with pulling the insulation ring 3 upward to drive the glass 4 upward, this is more in line with the daily force habit, and the user does not need to fix the glass 4 additionally.

[0036] It should be noted that, in practice, in order to simplify the processing technology of the glass cup 4, the glass cup 4 does not need to have an avoidance groove for the follower rod and the driving rod 8 on the inner side of the outer shell 1. The present device directly constrains the distance between the outer wall of the glass cup 4 located inside the outer shell 1 and the outer shell 1 to be smaller than the distance between the driving rod 8 close to the central axis of the outer shell 1 and the distance between the end of the limiting rod 5 close to the central axis of the outer shell 1 and the central axis of the outer shell 1, that is, the glass cup 4 as a whole is still a cylindrical structure, and the projection of the glass cup 4 on the horizontal plane does not overlap with the follower rod and the driving rod 8.

[0037] At the same time, the projection of the glass cup 4 on the horizontal plane does not overlap with the follower rod and the driving rod 8, which also causes a gap between the glass cup 4 and the inner wall of the outer shell 1. At this time, a limit ring 9 is arranged on the inner wall of the upper end of the outer shell 1 and is coaxially fixed to the outer shell 1. By constraining the inner wall of the limit ring 9 to abut against the glass cup 4, the gap between the glass cup 4 and the outer shell 1 can be made into a quasi-enclosed space with a small number of air outlets. By utilizing the characteristics of slow air flow speed and poor thermal conductivity of air in this gap, the heat transfer from the glass cup 4 to the outer shell 1 can be further weakened, thereby ensuring that the temperature of the outer shell 1 will not scald the user.

[0038] Furthermore, the existence of the limiting ring 9 can also block the follower ring 6 to ensure that the glass 4 cannot be separated from the outer shell 1 .

[0039] Furthermore, the present device also constrains the projection of each slide groove 2 on the vertical plane to be an L-shaped structure, that is, the width of the lower end of each slide groove 2 is greater than the width of its upper end. This allows the user to slide the thermal insulation ring 3 downward to drive the glass cup 4 to move upward, and the user can further rotate the thermal insulation ring 3 to drive the driving rod 8 to sink into the horizontal section of the slide groove 2. At this time, the driving rod 8 cannot move up and down relative to the outer shell 1 in the slide groove 2. At this time, the position between the glass cup 4 and the outer shell 1 can be fixed to ensure that the glass cup 4 can be normally located outside the outer shell 1.

[0040] In actual use, the utility model:

[0041] First, the follower ring 6 abuts against the inner wall of the lower end of the outer shell 1. At this time, the glass 4 is completely located in the outer shell 1. When the user grasps the insulation ring 3 to drive the device to move as a whole, the insulation ring 3, the outer shell 1, and the air gap can fully prevent the user from being scalded.

[0042] Afterwards, when the user wants to quickly dissipate the heat of the liquid inside the glass 4, he only needs to press the insulation ring 3 downward. At this time, the pull rope 7 drives the follower ring 6, that is, drives the glass 4 to move upward. When the driving rod 8 is located at the bottom of the slide groove 2, the insulation ring 3 is rotated horizontally to fix the position of the glass 4 protruding from the outer shell 1.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
