Technical Field

[0001] This utility model belongs to the field of water cup technology and relates to a magnetic cup. Background Technology

[0002] Most water cups on the market consist of a cup body and a lid, with the inside of the cup body always connected to the lid. This type of cup has the following disadvantages: First, when the cup is tilted, laid flat, or inverted, water inside the cup will flow into the lid. Even after opening the lid, if the cup is placed upright, residual water will still drip from the lid, affecting its use. Second, the lid of this type of cup needs to be screwed onto the cup body, making it inconvenient to open and close. If the lid is not screwed on tightly, the cup may leak. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems with existing tea cups by proposing a tea cup that can seal the inside of the cup when the lid is closed and allow the inside and outside of the cup to communicate when the lid is opened.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A magnetic cup includes a cup body and a cup lid, characterized in that a bushing is fixedly disposed inside the cup body, the bushing is provided with a water inlet channel connecting the inside and outside of the cup body, a magnet is provided on the cup lid, a magnet is provided on the bushing corresponding to the magnet one vertically, a plug is movably disposed inside the bushing, the plug can rise and fall relative to the bushing, and the magnet two is fixedly connected to the plug.

[0006] The cup lid is placed on the cup body. Magnet one and magnet two approach each other and attract each other to fix the cup lid and the cup body to form a closed lid. When magnet two is attracted, it drives the plug to rise and close the water inlet channel. After the lid is opened, magnet one and magnet two separate, magnet two and plug descend to reset and open the water inlet channel.

[0007] In the aforementioned magnetic cup, a sealing structure is also provided between the plug and the bushing. After the plug is raised, a circumferential seal is formed between the plug and the bushing through the sealing structure.

[0008] In the aforementioned magnetic cup, the sealing structure includes a sealing ring, which is fixed to the plug. When the plug is lifted, the sealing ring presses against the bushing.

[0009] In the aforementioned magnetic cup, a spring is provided between the plug and the bushing. After the cover is opened, the spring pushes the plug to descend and reset.

[0010] In the aforementioned magnetic cup, the bushing is further provided with a second sealing ring. The bushing is threaded onto the cup body, and the inner wall of the cup body is provided with a ring of bosses. When the bushing is screwed on, the second sealing ring is pressed against the bosses to form a circumferential seal between the bushing and the cup body.

[0011] In the aforementioned magnetic cup, the second magnet is fixed to the plug by a mounting sleeve, the second magnet is embedded in the inner cavity of the mounting sleeve, and the mounting sleeve is screwed to the top of the plug.

[0012] In the aforementioned magnetic cup, a guide structure is provided between the plug and the bushing. The guide structure includes a guide block fixed on the plug and a guide groove opened on the bushing. Several guide blocks are distributed at intervals along the circumference of the plug, and each guide block is inserted into the corresponding guide groove. When the plug is raised or lowered, the guide blocks are raised or lowered synchronously along the guide groove.

[0013] In the aforementioned magnetic cup, the bushing is provided with several guide strips that correspond one-to-one with the positions of each guide block, and guide grooves are formed on the guide strips.

[0014] In the aforementioned magnetic cup, the bushing is further provided with a connecting ring that is fixedly connected to each guide bar. The top of the plug extends upward out of the connecting ring and is fixedly connected to the mounting sleeve. After the cover is opened, the spring pushes the plug down, and the mounting sleeve presses against the connecting ring.

[0015] In the aforementioned magnetic cup, the magnetic cup also includes a tea container, which is fastened and fixed to the bushing.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. After the lid is closed, the magnetic attraction causes the second magnet and the plug to rise, and the first sealing ring is pressed against the bushing, forming a seal between the plug and the bushing, closing the water inlet channel and preventing water from flowing into the lid. After the lid is opened, the second magnet demagnetizes, the plug and the first sealing ring descend, the water inlet channel opens, and the inside and outside of the cup are connected for drinking.

[0018] 2. There is no connecting structure between the lid and the cup body. After the lid is on, it can be fixed by the attraction between magnet one and magnet two, making it convenient and quick to open and close. Moreover, the lid has no internal threads, so it can be used as a teacup for drinking water after opening. Attached Figure Description

The bushing 7 has a water inlet channel connecting the inside and outside of the cup body 1. A magnet 4 is provided on the cup lid 2. A magnet 5 is provided on the bushing 7, which corresponds to the magnet 4 vertically. A plug 6 is movably provided inside the bushing 7. The plug 6 can rise and fall relative to the bushing 7. The magnet 5 is fixedly connected to the plug 6.

[0028] like Figure 2 As shown, the cup lid 2 covers the cup body 1. Magnet 4 and magnet 5 approach and attract each other, so that the cup lid 2 and the cup body 1 are relatively fixed to form a closed lid. When magnet 5 is attracted, it drives the plug 6 to rise and close the water inlet channel. Figure 3 As shown, after the cover is opened, magnet 4 separates from magnet 5, magnet 5 and plug 6 descend to reset and open the water inlet channel. A spring 8 is provided between plug 6 and bushing 7. After the cover is opened, spring 8 pushes plug 6 to descend to reset.

[0029] A sealing structure is also provided between the plug 6 and the bushing 7. After the plug 6 is raised, a circumferential seal is formed between the plug 6 and the bushing 7 through this sealing structure. The sealing structure includes a first sealing ring 9, which is fixed on the plug 6. When the plug 6 is raised, the first sealing ring 9 is pressed against the bushing 7. The bushing 7 is also provided with a second sealing ring 10. The bushing 7 is threadedly connected to the cup body 1. The inner wall of the cup body 1 is provided with a boss 11. When the bushing 7 is screwed on, the second sealing ring 10 is pressed against the boss 11, so that a circumferential seal is formed between the bushing 7 and the cup body 1.

[0030] like Figure 5As shown, a guide structure is also provided between the plug 6 and the bushing 7. This guide structure includes guide blocks 13 fixed on the plug 6 and guide grooves 14 formed on the bushing 7. Several guide blocks 13 are distributed at intervals along the circumference of the plug 6, and each guide block 13 is inserted into its corresponding guide groove 14. When the plug 6 is raised or lowered, the guide blocks 13 are raised or lowered synchronously along the guide grooves 14. The bushing 7 is provided with several guide strips 15 that correspond one-to-one with the positions of each guide block 13, and the guide grooves 14 are formed on the guide strips 15.

[0031] like Figure 4 As shown, the second magnet 5 is fixed to the plug 6 by a mounting sleeve 12. The second magnet 5 is embedded in the inner cavity of the mounting sleeve 12, and the mounting sleeve 12 is screwed to the top of the plug 6. The bushing 7 is also provided with a connecting ring 16 fixed to each guide bar 15. The top of the plug 6 extends upward out of the connecting ring 16 and is fixed to the mounting sleeve 12. After the cover is opened, the spring 8 pushes the plug 6 down, and the mounting sleeve 12 presses against the connecting ring 16.

[0032] The magnetic cup also includes a tea compartment 3, which is fastened and fixed to the bushing 7.

[0033] The mounting sleeve 12 of this utility model includes an outer shell and a sealing sleeve disposed within the outer shell. A magnet 5 is fixedly embedded within the sealing sleeve. An outer shell 2 is fixedly disposed at the bottom of the plug 6, and a sealing ring 9 is fitted onto the outer shell 2. The bushing 7 includes a liner and an outer shell 3 covering the liner, with a sealing ring 3 between the outer shell 3 and the liner. The outer shells 1, 2, and 3 are all metal parts, made of stainless steel or titanium.

[0034] Example 2

[0035] Unlike Embodiment 1, this embodiment does not have a spring 8 between the plug 6 and the bushing 7. There is a certain amount of friction between the plug 6 and the connecting ring 16 on the bushing 7. After opening the lid, the magnet 5 loses its magnetism, and the magnet 5 and the plug 6 overcome the aforementioned friction and descend due to their own weight. When drinking water, the user tilts the cup, and the plug 6 remains stationary relative to the bushing 7 under the action of friction. Therefore, no seal is formed between the plug 6 and the bushing 7, allowing for drinking water.
