TECHNICAL FIELD

[0001] The utility model relates to the field of vacuum cup design, especially to a vacuum cup convenient to open and drink. BACKGROUND

[0002] Vacuum cups, as indispensable daily necessities in modern life, have won wide favor and application with their excellent heat preservation performance. Such cups, through the adoption of double-layer or multi-layer structure design and the filling of vacuum or heat insulation materials between the two layers, effectively isolate the influence of external temperature on the internal liquid, making it possible to keep cold drinks cool in summer or hot drinks warm in cold winter. Vacuum cups not only meet people's demand for temperature control of drinks, but also become ideal companions for outdoor exploration, daily commuting and office work due to their portability, durability and other characteristics.

[0003] The vacuum cups on the current market have shown very high technical level in terms of heat preservation effect. Thanks to advanced production processes and material selection, these vacuum cups can maintain the temperature of drinks for a long time, even after several hours of placement, they can still better maintain the initial temperature. This outstanding performance is largely due to the excellent airtightness design of the vacuum cup, through the tight sealing cover and efficient sealing structure, effectively preventing heat loss through air convection and conduction, while also avoiding the intrusion of external moisture and impurities, further ensuring the hygiene and safety of the drinks.

[0004] However, it is this excellent airtightness design of the vacuum cup that has brought inconvenience to users in some specific situations. Especially when the vacuum cup contains hot drinks and has been for a period of time, due to the gradual evaporation of internal gas with the decrease of temperature, a negative pressure state is formed inside the vacuum cup. When the internal and external pressure difference reaches a certain degree, the user will find it extremely difficult to open the lid of the vacuum cup, or even completely unable to open it. In order to alleviate this problem, some users have to resort to the method of immersing the vacuum cup in hot water, which expands the internal gas through heating, thereby reducing the internal and external pressure difference, but this undoubtedly increases the complexity and inconvenience of use.

Those skilled in the art will appreciate that these descriptions are only descriptive, exemplary and should not be interpreted as limiting the scope of protection of the utility model.

[0023] It should be noted that: similar reference numerals represent similar items in the following drawings, therefore, once an item is defined in one drawing, it can not be further defined and explained in the subsequent drawings.

[0024] This embodiment mainly describes the structure of the vacuum cup, as follows:

[0025] A kind of vacuum cup convenient to open cover and drink, such as Figures 1-5As shown, including the vacuum cup 1, cup cover 101, exhaust assembly 2, limit assembly and anti-touch assembly 8, the vacuum cup 1 is provided with cup cover 101, cup cover 101 is threadedly connected with vacuum cup 1, so as to ensure good air tightness, cup cover 101 is provided with exhaust assembly 2 for discharging gas in vacuum cup 1, exhaust assembly 2 mainly includes pressing rod 23 and sealing plate 24, sealing plate 24 is moved by pressing rod 23, so that the inside and outside of vacuum cup 1 are communicated, the atmospheric pressure is balanced, cup cover 101 is provided with limit assembly, limit assembly is used for maintaining the exhaust state of exhaust assembly 2, limit assembly mainly includes the cooperation of clamping groove 3 on pressing rod 23 and top plate 4, limiting the movement of pressing rod 23, so as to maintain the position of pressing rod 23, exhaust assembly 2 is provided with anti-touch assembly 8, anti-touch assembly 8 is used for limiting exhaust assembly 2 to exhaust vacuum cup 1.

[0026] As shown in Figure 2 and Figure 3 , exhaust assembly 2 further includes fixed plate 21 and return spring 25, through hole is formed in cup cover 101, fixed plate 21 is connected in through hole, exhaust hole 22 is formed in fixed plate 21, pressing rod 23 is slidably connected with fixed plate 21, pressing rod 23 protrudes from cup cover 101 at top, sealing plate 24 is connected with bottom of through hole of cup cover 101, return spring 25 is sleeved on pressing rod 23, top of return spring 25 is connected with fixed plate 21, bottom of return spring 25 is connected with sealing plate 24.

[0027] As shown in Figure 2 and Figure 4 , limit assembly further includes connecting piece 5, elastic piece 6 and operation plate 7, clamping groove 3 is formed in pressing rod 23, connecting piece 5 is slidably connected in cup cover 101, operation plate 7 is connected with top of connecting piece 5, operation plate 7 is higher than cup cover 101, top plate 4 is connected with bottom of connecting piece 5, top plate 4 is limitedly matched with clamping groove 3, four elastic pieces 6 are arranged between connecting piece 5 and cup cover 101, one end of elastic piece 6 is fixedly connected with connecting piece 5, the other end of elastic piece 6 is fixedly connected with cup cover 101.

[0028] As shown in Figure 1 and Figure 5 , anti-touch assembly 8 includes magnetic ring 81 and metal sleeve ring 82, metal sleeve ring 82 is connected with top of pressing rod 23, magnetic ring 81 is connected with top of through hole of cup cover 101, magnetic ring 81 is magnetically matched with metal sleeve ring 82, when metal sleeve ring 82 moves with pressing rod 23, metal sleeve ring 82 is slidably connected with cup cover 101, the rebound force of return spring 25 is greater than the magnetic force between metal sleeve ring 82 and magnetic ring 81, and recesses are arranged around metal sleeve ring 82, which can discharge gas in vacuum cup 1.

[0029] When the user fills the vacuum cup 1 with hot water and covers the cup cover 101, the hot water in the vacuum cup 1 partially vaporizes during the movement of the vacuum cup 1, the air pressure in the vacuum cup 1 rises, and the gas pushes the sealing plate 24 to tightly adhere to the cup cover 101, thereby ensuring the air tightness and heat preservation effect of the vacuum cup 1. When the user needs to open the cup cover 101 to drink water, it is difficult to open the cup cover 101 by simply rotating the cup cover 101, so the user presses the pressing rod 23 to press the sealing plate 24 downward. During the downward movement of the sealing plate 24, the through hole of the cup cover 101 connects the inside and outside air, the gas in the vacuum cup 1 is discharged, and if the vacuum cup 1 is large or the shaking degree of the vacuum cup 1 is large, the pressure difference between the inside and outside is large, so the top plate 4 is inserted into the clamping groove 3 of the pressing rod 23 to maintain the state of gas discharge, so that the user does not need to press the pressing rod 23 all the time. After the inside and outside pressure balance, the user rotates the cup cover 101 to drink water. In addition, when the user carries the vacuum cup 1, the anti-touch assembly 8 can prevent the pressing rod 23 from being contacted or pressed by other objects to slide, thereby preventing the water from flowing out from the top of the cup cover 101 when the vacuum cup 1 is tilted.

[0030] When discharging the gas, the user presses the pressing rod 23 downward, the pressing rod 23 pushes the sealing plate 24 to move downward, the pressing rod 23 slides in the fixed plate 21, one end of the reset spring 25 is pulled by the sealing plate 24 to move downward, thereby stretching the compression spring, and after the sealing plate 24 is separated from the top of the cup cover 101, the gas is discharged from the through hole of the cup cover 101, thereby balancing the inside and outside pressure. After the gas is discharged, the pressing rod 23 is released, the reset spring 25 rebounds to reset the pressing rod 23 and the sealing plate 24.

[0031] When the vacuum cup 1 is not discharging the gas, the elastic member 6 is in a stretched state, when the pressing rod 23 moves downward, the top plate 4 is aligned with the clamping groove 3 on the side of the pressing rod 23, the elastic member 6 rebounds, the connecting member 5 pushes the top plate 4 to insert into the clamping groove 3, thereby locking the position of the pressing rod 23 and maintaining the state of gas discharge. After the gas discharge is completed, the operating plate 7 is pushed, the operating plate 7 drives the connecting member 5 to stretch the elastic member 6, and the connecting member 5 drives the top plate 4 to move away from the clamping groove 3. At this time, the user releases the pressing rod 23, so the pressing rod 23 is reset upward under the action of the reset spring 25. At this time, the pressing rod 23 abuts against the top plate 4 to maintain the stretched state of the elastic member 6.

[0032] When the pressing rod 23 moves, the metal sleeve ring 82 also moves, when the metal sleeve ring 82 passes through the magnetic ring 81, the magnetic force will limit the relative displacement between the metal sleeve ring 82 and the magnetic ring 81, thereby limiting the arbitrary sliding of the pressing rod 23. In addition, the reset spring 25 is in a stretched state in the heat preservation state, thereby maintaining the sealing between the sealing plate 24 and the cup cover 101.

[0033] As shown in FIG. 8, the pressing rod 23 is provided with a metal sleeve ring 82, and the pressing rod 23 is provided with a magnetic ring 81. Figure 5 As shown in FIG. 8, the pressing rod 23 is provided with a metal sleeve ring 82, and the pressing rod 23 is provided with a magnetic ring 81.

[0034] The rubber sleeve 9 can optimize the user's experience of pressing the pressing rod 23 and protect the user's fingers from being scratched by the metal part, ensuring the user's safety.

[0035] As shown in Figure 4 The operation plate 7 is connected with a rubber pad 10.

[0036] The rubber pad 10 can optimize the user's experience of using the operation plate 7 and protect the user's fingers.

[0037] As shown in Figure 3 The sealing plate 24 is provided with a sealing pad 11 with a diameter equal to that of the through hole of the cup cover 101.

[0038] The soft sealing pad 11 can further optimize the sealing effect between the sealing plate 24 and the cup cover 101.

[0039] As shown in Figure 1 The heat-insulating cup 1 is connected with a sponge pad 12 at the bottom.

[0040] The sponge pad 12 with rough texture on the bottom surface can enhance the stability of the heat-insulating cup 1.

[0041] After the heat-insulating cup 1 is filled with hot water and the cup cover 101 is covered, the screw connection ensures good airtightness to maintain the water temperature. With the movement of the heat-insulating cup 1 or changes in the environment, the internal hot water gasifies to cause the air pressure to rise, and the sealing plate 24 tightly adheres to the bottom of the through hole of the cup cover 101 under the action of the air pressure, ensuring the heat-insulating effect. When the cup cover 101 needs to be opened, if it is difficult to open due to the difference between the internal and external air pressures, the user can press the sealing plate 24 downward by pressing the pressing rod 23, so that the through hole is connected with the internal and external air to balance the air pressure. In this process, the return spring 25 is stretched, and after the gas is discharged, the pressing rod 23 is released, and the spring rebounds to reset the pressing rod 23 and the sealing plate 24. If the exhaust state needs to be maintained, the top plate 4 in the limiting assembly is inserted into the clamping groove 3 of the pressing rod 23 under the action of the elastic element 6, locking the position of the pressing rod 23. The magnetic ring 81 in the anti-touch assembly 8 magnetically cooperates with the metal sleeve ring 82, and when the metal sleeve ring 82 moves to the magnetic ring 81 along with the pressing rod 23, the magnetic force limits the relative displacement to prevent the pressing rod 23 from being accidentally touched and sliding, ensuring that the heat-insulating cup 1 will not leak water due to tilting during carrying. In addition, the rubber sleeve 9 and the rubber pad 10 optimize the user's experience of using the pressing rod 23 and the operation plate 7, respectively, and protect the user's fingers; the sealing pad 11 enhances the sealing effect; and the sponge pad 12 with rough texture on the bottom surface enhances the stability of the heat-insulating cup 1.
