Description

Technical Field

[0001] This utility model relates to a hot water cup, specifically a wireless hot water cup lid structure. Background Technology

[0002] Water cups, as a type of vessel specifically for drinking water, have been widely used from ancient times to the present. Depending on the specific needs, they are further classified into categories such as thermos cups. When hot water is needed in the wild, it is necessary to heat the water before drinking, hence the need for a thermos cup to heat the water.

[0003] However, current water cups on the market have a significant design flaw: they lack a structure specifically designed to expel the steam generated during heating and boiling. This design flaw causes steam to continuously accumulate inside the sealed cup. When the steam pressure violently impacts the cup wall, it can not only cause the cup to wobble and tip over, but also potentially cause it to burst due to the continuously rising internal pressure, posing a serious safety hazard. Therefore, this utility model provides a wireless hot water cup lid structure to solve the aforementioned problems. Utility Model Content

[0027] The cup lid assembly includes an outer frame 20, a main frame 21, a top cover 22, and a connecting cover 23. The outer wall of the outer frame 20 is provided with a plurality of first guide rails arranged in a circle, and the inner wall of the outer frame 20 is provided with a plurality of first slots arranged in a circle. The outer frame 20 is sleeved on the outer wall of the first guide rails on the main frame 21 through the first slots. The top of the outer wall of the cup body 10 and the inner wall of the main frame 21 are both provided with mutually mating threads. Then, the main frame 21 is installed on the top of the cup body 10 and sealed by being screwed into the threads on the top of the cup body 10 through the main frame 21. The top of the main frame 21 is provided with a first annular groove. The connecting cover 23 is connected to the inner wall of the first groove on the main frame 21 by pressing. The top of the connecting cover 23 is provided with a second groove. The top cover 22 is connected to the inner wall of the second groove on the connecting cover 23.

[0028] The cup lid assembly is equipped with an exhaust component for steam discharge. The exhaust component includes a first air pipe 40, a second air pipe 41, a breathable membrane 42, and an air hole 43. The first air pipe 40 is installed on the axis of the main frame 21, and the second air pipe 41 is installed on the axis of the connecting cover 23 near the main frame 21. The first air pipe 40 has multiple second slots arranged in a circle. The outer wall of the second air pipe 41 is fixedly connected with multiple second guide rails arranged in a circle. The second guide rails on the outer wall of the second air pipe 41 are inserted into the inner wall of the second slots on the first air pipe 40. The breathable membrane 42 is installed on the inner wall of the connecting cover 23. The air hole 43 is opened on the outer wall of the top cover 22 and completely penetrates the top cover 22. When the water in the cup body 10 is heated, the generated steam can pass through the first air pipe 40 and the second air pipe 41, pass through the breathable membrane 42, and then be discharged through the air hole 43.

[0029] A mounting assembly for accommodating the connecting cover 23 and the first air pipe 40 is installed at the main frame 21.

[0030] See Figure 4The installation assembly includes a locking member 50 and a limiting plate 51. A first through hole is opened at the axial position of the first air pipe 40, a second through hole is opened at the bottom of the second air pipe 41, and multiple circumferentially arranged discharge holes are opened at the top of the second air pipe 41, which are connected to the second through hole. A limiting groove adapted to the outer wall of the first air pipe 40 is opened at the axial position of the limiting plate 51. The limiting plate 51 is installed on the inner wall of the main frame 21 and sleeved on the outer wall of the first air pipe 40 through the limiting groove. The locking member 50 passes through the first through hole in the first air pipe 40 and is installed on the inner wall of the second air pipe 41. The bottom end of the locking member 50 is installed on the inner wall of the first air pipe 40. When installation is required, the second air pipe 41 is inserted into the inner wall of the first air pipe 40, and the limiting plate 51 is inserted into the outer wall of the first air pipe 40 for limiting. Then the limiting plate 51 is installed through the first air pipe 40 and installed on the inner wall of the second air pipe 41, so that the connecting cover 23 and the main frame 21 can be installed as a whole.

[0031] See Figure 3 The breathable membrane 42 is made of polyethylene and is located between the second air pipe 41 and the top cover 22. Gas can pass through the breathable membrane 42 and be discharged through the air hole 43. It can also block water and prevent water from passing through.

[0032] Example 2, see Figure 5 A through-hole fixing groove is provided at the axis position of the top cover 22. An installation plate 60 is fixedly connected to the inner wall of the fixing groove. A condensation component for liquefying water vapor is installed at the bottom of the installation plate 60, and a collection component for collecting condensate is installed at the axis position of the installation plate 60. A drainage component for draining water is installed on the collection component.

[0033] See Figure 6 The condensation assembly includes a condenser plate 61 and guide blocks 62. The condenser plate 61 is fixedly connected to the bottom axis of the mounting plate 60. A circular connecting plate is provided at the bottom of the condenser plate 61. The cross-section of the condenser plate 61 at both ends of the connecting plate is arc-shaped and adjacent parts are on the same plane as the connecting plate. The condenser plate 61 is made of stainless steel. Multiple guide blocks 62 arranged in a circular pattern are fixedly connected to the bottom outer wall of the connecting plate on the condenser plate 61. The guide blocks 62 are conical. When water vapor passes through the breathable membrane 42 and enters the top cover 22, the water vapor can come into contact with the condenser plate 61 and condense. The water produced by condensation then flows along the arc surface of the condenser plate 61 to the connecting plate, and then flows and drips along the conical surface of the guide blocks 62.

[0034] See Figure 7The collection assembly includes a collection pipe 80, a storage ring 90, and a water pipe 92. A through fixing hole is provided at the axial position of the mounting plate 60 and the condensation plate 61. The collection pipe 80 is fixedly connected to the inner wall of the fixing hole. Multiple fixing rods 91 arranged in a circle are fixedly connected to the outer wall of the collection pipe 80. The storage ring 90 is circular and fixedly connected to the outer wall of the fixing rods 91. The storage ring 90 is located at the bottom of the guide block 62. The two ends of the water pipe 92 are respectively connected to the inner wall of the storage ring 90 and the collection pipe 80. The connection between the water pipe 92 and the collection pipe 80 is lower than the horizontal plane of the connection between the water pipe 92 and the storage ring 90. When water drips from the bottom of the guide block 62, it falls into the storage ring 90 and is transported to the bottom of the collection pipe 80 for collection through the water pipe 92.

[0035] See Figure 8 The drainage assembly includes a protective sleeve 70, a connecting rod 73, and a piston plate 74. The piston plate 74 is slidably connected to the inner wall of the bottom of the collection pipe 80. The top of the mounting plate 60 has an annular threaded groove. The protective sleeve 70 is threadedly connected to the inner wall of the threaded groove on the mounting plate 60. The connecting rod 73 is fixedly connected to the opposing walls of the protective sleeve 70 and the piston plate 74. The outer wall of the protective sleeve 70 has multiple circumferentially arranged drainage holes 72, and an adjusting block 71 is fixedly connected to the top axis of the protective sleeve 70. The middle of the inner wall of the collection pipe 80 is fixedly connected to the protective sleeve 70. A fixed ring 81 is fixedly connected to the piston plate 74. A return spring 82 is fixedly connected to the wall surface opposite the fixed ring 81 and the piston plate 74. When drainage is required, the adjusting block 71 is rotated to screw the protective sleeve 70 out of the threaded groove on the mounting plate 60. The cup lid assembly is then inverted, and the adjusting block 71 is pulled. The adjusting block 71 can then pull the piston plate 74 to slide in the collection pipe 80 through the protective sleeve 70 and the connecting rod 73. Then, the water is discharged to the protective sleeve 70 by gravity and the movement of the piston plate 74, and then discharged through the drain hole 72.

[0036] For more details, please refer to Figure 8 A fixed plate 85 is fixedly connected to the inner wall of the collecting pipe 80. The fixed plate 85 has multiple connecting holes arranged in a circle. An adjusting plate 83 is fixedly connected to the outer wall of the connecting rod 73. A sealing rod 84 that matches the connecting hole is fixedly connected to the bottom of the adjusting plate 83. The adjusting plate 83 has multiple through grooves arranged in a circle for water to pass through. Specifically, when drainage is not performed, the sealing rod 84 blocks the connecting hole to prevent external impurities from entering. When drainage is performed, the adjusting plate 83 is moved by the connecting rod 73, which then moves the sealing rod 84 out of the connecting hole, allowing water to pass through the connecting hole and the through grooves on the adjusting plate 83 for drainage.

[0037] The working principle of this utility model is as follows: when heating is required, water is added into the cup body 10, and the cup lid assembly is screwed into the top of the cup body 10 through the threads on the main frame 21. At this time, the water is heated by the heating pad 31 on the heating base 30.

[0038] When water is heated to boiling and produces steam, the steam can pass through the first air pipe 40 and the second air pipe 41 and pass through the breathable membrane 42 to be discharged from the air hole 43 at the top cover 22. The breathable membrane 42 also blocks the water, preventing the water from passing through the breathable membrane 42 and being discharged through the air hole 43.

[0039] When water vapor is delivered to the top cover 22, the condenser plate 61 condenses the water vapor into water droplets. The water droplets flow along the arc surface of the condenser plate 61 to the guide block 62 and drip into the storage ring 90. They are then transported to the collection pipe 80 through the water pipe 92 for collection.

[0040] When drainage is required, the protective sleeve 70 is unscrewed, the cup lid assembly is inverted, and then the adjusting block 71 is pulled to move the piston plate 74 through the protective sleeve 70 and the connecting rod 73. Then, under the pressure of water gravity and the piston plate 74, the water is discharged from the collection pipe 80 into the protective sleeve 70 and drained through the drain hole 72 on the protective sleeve 70.

[0041] When in use, the cup lid assembly allows the steam generated when water is heated to boiling to be released, preventing the internal steam from colliding with the inner wall of the cup body 10 and causing the cup body 10 to shake and tip over, resulting in damage from the cup body 10 falling off. It also maintains the air pressure balance inside the cup body 10, preventing excessive internal air pressure from causing an explosion.

[0042] The condensation, collection, and drainage components are designed to collect and discharge water vapor, preventing it from condensing at the top cover 22 and accumulating at the breathable membrane 42. This would prevent the breathable membrane 42 from being deformed by pressure, affecting its water vapor passage efficiency. Furthermore, it prevents water from contaminating the breathable membrane 42 at the point of contact with the top cover 22, thus ensuring the safety of drinking water.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
