Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, specifically to a thermos cup with a magnetic lid. Background Technology

[0002] A thermos is a portable container with a double-walled vacuum design that keeps drinks warm by insulating them, typically for 6-12 hours. Modern people love it not only for its practicality—keeping hot tea warm in winter and iced drinks warm in summer—but also because it carries a sense of ritual in life: the condensation on the cup's walls acts as a marker of time, and the rising steam from the rim conveys subtle acts of care. From student desks to office meetings, from gyms to outdoor camping, this small container silently witnesses the modern philosophy of "running with warmth" in life.

[0003] Traditional thermos cup lids are mostly installed using threads, requiring multiple rotations to remove and reinstall them before drinking. This is inefficient, provides a poor user experience, and fails to meet the needs of some users. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic lid thermos cup that solves the problems of low disassembly and assembly efficiency and poor user experience of the lids installed by thread in the prior art.

[0005] This utility model provides the following technical solution: a magnetic lid thermos cup, comprising:

[0006] The thermos cup body, with a handle rotatably connected to the outer wall of the thermos cup body;

[0007] A magnetic connection mechanism is provided on the body of the thermos cup, and the magnetic connection mechanism is used to improve the opening and closing efficiency of the opening of the thermos cup body;

[0008] A pressure relief protection mechanism is installed on the outer wall of the thermos body, and the pressure relief protection mechanism is used to increase the safety when storing high-temperature liquids.

[0009] The magnetic connection mechanism includes a cover plate and an extended side plate. The cover plate is movably abutted against the top of the thermos body. The extended side plate is fixedly installed on the outer wall of the thermos body. A protrusion is fixedly connected to the bottom of the cover plate. A groove is formed on the top of the extended side plate. The protrusion is movably inserted into the inner cavity of the groove. A metal sheet is fixedly installed on the inner wall of the top of the extended side plate. An electromagnet is fixedly installed on the inner wall of the cover plate. The bottom of the electromagnet is magnetically connected to the top of the metal sheet.

[0010] As a preferred embodiment of the above technical solution, a raised ring is fixedly installed at the bottom of the cover plate, and a rubber ring is fixedly sleeved on the outer wall of the raised ring, with the outer wall of the rubber ring being movably connected to the inner wall of the thermos body.

[0011] As a preferred embodiment of the above technical solution, a battery box is fixedly installed on the top of the cover plate, a handle is fixedly installed on the top of the cover plate, and a switch is fixedly installed on the top of the handle.

[0012] As a preferred embodiment of the above technical solution, the pressure relief protection mechanism includes a square tube, which is fixedly connected to the outer wall of the thermos body. A bent tube is fixedly connected to the end of the square tube away from the thermos body, and a round tube is fixedly connected to the end of the bent tube away from the square tube.

[0013] As a preferred embodiment of the above technical solution, an inner partition is fixedly installed on the inner wall of the square tube, a through hole is opened at the top of the inner partition, a threaded rod is threadedly connected to the top of the square tube, the bottom of the threaded rod extends into the inner cavity of the square tube and is rotatably connected to a closing block, and a rotating component is fixedly installed at the top of the threaded rod.

[0014] As a preferred embodiment of the above technical solution, a circular block one is fixedly installed on the inner wall of the circular tube, and a circular block two located below the circular block one is fixedly installed on the inner wall of the circular tube. A circular hole is opened at the top of the circular block two, an elastic element is fixedly installed at the top of the circular block two, and a pin is fixedly installed at the top of the elastic element. The pin is slidably connected to the inner wall of the circular block one.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a magnetic connection mechanism. After the cover is inserted into the top of the thermos body, an electromagnet is activated to generate magnetic force, which then magnetically connects to the top of the metal plate, thus positioning the cover. Conversely, de-energizing the electromagnet allows the cover to be pulled out from the top of the thermos body. This design eliminates the need for cumbersome rotation operations, improving assembly and disassembly efficiency, increasing convenience, and meeting the needs of some users.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a magnetic lid thermos cup, comprising:

[0025] The thermos body 1 has a handle 11 rotatably connected to the outer wall of the thermos body 1.

[0026] Magnetic connection mechanism 2 is installed on the body 1 of the thermos cup. The magnetic connection mechanism 2 is used to improve the opening and closing efficiency of the opening of the body 1 of the thermos cup.

[0027] Pressure relief protection mechanism 3 is installed on the outer wall of the thermos body 1. Pressure relief protection mechanism 3 is used to increase the safety when storing high temperature liquids.

[0028] The magnetic connection mechanism 2 includes a cover plate 21 and an extended side plate 23. The cover plate 21 is movably abutted against the top of the thermos body 1. The extended side plate 23 is fixedly installed on the outer wall of the thermos body 1. A protrusion 22 is fixedly connected to the bottom of the cover plate 21. A groove 24 is formed on the top of the extended side plate 23, and the protrusion 22 is movably inserted into the inner cavity of the groove 24. A metal sheet 25 is fixedly installed on the inner wall of the top of the extended side plate 23. An electromagnet 26 is fixedly installed on the inner wall of the cover plate 21. The bottom of the electromagnet 26 is connected to the metal sheet 25. The top magnetic connection allows the cover plate 21 to be inserted into the top of the thermos body 1 when it is installed. Then, the electromagnet 26 is controlled to work, which generates magnetic force and magnetically connects to the top of the metal plate 25, thus positioning the cover plate 21. Conversely, the electromagnet 26 is de-energized, and the cover plate 21 can be pulled out from the top of the thermos body 1, thereby improving the efficiency of disassembly and assembly. When the cover plate 21 is inserted, the protrusion 22 is simultaneously inserted into the groove 24, which limits the horizontal rotation of the cover plate 21.

[0029] As one implementation method in this embodiment, such as Figure 2 As shown, a raised ring 27 is fixedly installed at the bottom of the cover plate 21. A rubber ring 271 is fixedly sleeved on the outer wall of the raised ring 27. The outer wall of the rubber ring 271 is movably connected to the inner wall of the thermos body 1. When the cover plate 21 is inserted, the raised ring 27 is inserted into the inside of the thermos body 1. At this time, the design of the rubber ring 271 can seal the gap at the connection between the raised ring 27 and the thermos body 1.

[0030] As one implementation method in this embodiment, such as Figure 2 As shown, a battery box 28 is fixedly installed on the top of the cover plate 21, a handle 29 is fixedly installed on the top of the cover plate 21, and a switch 291 is fixedly installed on the top of the handle 29. The battery box 28 contains a battery, which powers the electromagnet 26. The switch 291 is electrically connected to the electromagnet 26 and the battery, and the electromagnet 26 can be turned on and off from the switch 291 for convenient use. It is worth noting that the electromagnet 26, switch 291, and battery in this solution are commercially available devices that can be purchased by those skilled in the art. The devices have not been structurally modified in this paper. Therefore, those skilled in the art are familiar with their working principle based on their professional knowledge and can apply it skillfully. Therefore, this paper will not elaborate on this. At the same time, this solution aims to protect the physical structure, but does not protect the circuit. The proposed processing circuit in this paper is only to supplement the explanation of the feasibility and authenticity of this utility model. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0031] As one implementation method in this embodiment, such as Figure 1 As shown, the pressure relief protection mechanism 3 includes a square tube 31, which is fixedly connected to the outer wall of the thermos body 1. A bent tube 32 is fixedly connected to the end of the square tube 31 away from the thermos body 1, and a round tube 33 is fixedly connected to the end of the bent tube 32 away from the square tube 31. Through the design of the bent tube 32, the exhaust end of the round tube 33 can be made to face downward, which increases the safety when holding it from the handle 11.

[0032] As one implementation method in this embodiment, such as Figure 3 As shown, an inner partition 311 is fixedly installed on the inner wall of the square tube 31. A through hole 312 is opened at the top of the inner partition 311. A threaded rod 313 is threadedly connected to the top of the square tube 31. The bottom of the threaded rod 313 extends into the inner cavity of the square tube 31 and is rotatably connected to a closing block 315. A rotating part 314 is fixedly installed at the top of the threaded rod 313. The threaded rod 313 can be rotated from the rotating part 314 to adjust the height of the closing block 315. When the closing block 315 is closed at the top of the through hole 312, the inner cavity of the square tube 31 is in a closed state. When the closing block 315 is away from the top of the through hole 312, the inner cavity of the square tube 31 is in an open state. The round tube 33 is used as a whole for pressure relief protection. When the body of the thermos cup 1 stores high-temperature liquid, the inner cavity of the square tube 31 should be adjusted to the open state.

[0033] As one implementation method in this embodiment, such as Figure 4 , Figure 5 As shown, a circular block 331 is fixedly installed on the inner wall of the circular tube 33, and a circular block 333 located below the circular block 331 is fixedly installed on the inner wall of the circular tube 33. A circular hole 334 is opened on the top of the circular block 333, and an elastic element 335 is fixedly installed on the top of the circular block 333. A pin 332 is fixedly installed on the top of the elastic element 335. The pin 332 is slidably connected to the inner wall of the circular block 331. When the inner cavity of the square tube 31 is adjusted to the open state, the inner cavities of the circular tube 33, the bent tube 32, the square tube 31 and the thermos body 1 are connected. The air pressure inside the thermos body 1 will push the pin 332, causing the pin 332 to slide on the inner wall of the circular block 331, while compressing the elastic element 335. Then, high-pressure gas can be discharged from the gap of the pin 332 to achieve the function of pressure relief protection.

[0034] Working principle: During use, when installing the cover plate 21, insert the cover plate 21 into the top of the thermos body 1, and then control the electromagnet 26 to work. It can generate magnetic force when energized, and magnetically connect to the top of the metal plate 25 to realize the positioning function of the cover plate 21. When removing the cover plate 21, control the electromagnet 26 to de-energize, and the cover plate 21 can be pulled out from the top of the thermos body 1. When the thermos body 1 stores high-temperature liquid, the threaded rod 313 is rotated from the rotating part 314, so that the closing block 315 moves away from the top of the through hole 312, and the inner cavity of the square tube 31 is adjusted to the open state. The air pressure inside the thermos body 1 will push the pin 332, causing the pin 332 to slide on the inner wall of the circular block 331, while compressing the elastic part 335. Then, high-pressure gas can be discharged from the gap of the pin 332 to realize the function of pressure relief protection.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
