DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0027] This embodiment mainly describes a thermos cup with an easily detachable lid, as follows:

[0028] like Figure 1 、 Figure 2 As shown, a thermos cup with an easily detachable cup lid comprises a cup body 5, a cup lid, and a connector 3 with a handle 4 connecting the cup body 5 and the cup lid. Specifically, the connector 3 is fixed to the cup lid and the cup body 5 respectively by threaded connections. The cup body 5 is a double-layer vacuum structure and is made of metal material, which improves the heat preservation performance while being strong and durable. The connector 3 and the cup lid are made of plastic material to reduce the overall weight of the thermos cup. At the same time, the design of the handle 4 makes it convenient for users to carry the thermos cup.

[0029] like Figure 3 As shown, the cup cover includes a cover core 2 and an upper cover 1 rotatably connected to the cover core 2, a groove 21 is provided on the upper cover 1, and a group of opposite through-type connecting holes 11 are provided on the left and right side walls of the groove 21, a boss 15 is provided on the cover core 2, a through hole is provided in the boss 15, and a telescopic member 16 with retractable ends is provided in the through hole, and the telescopic member 16 can be fixedly or rotatably set in the boss 15, the boss 15 extends into the groove 21, and the retractable parts at both ends are inserted into the connecting holes 11 to realize the connection between the upper cover 1 and the cover core 2. When the user needs to remove the upper cover 1 from the cover core 2 for cleaning, the retractable ends of the telescopic member 16 can be retracted toward the boss 15 by pressing or other means, so that it is removed from the connecting hole 11, and the upper cover 1 can be separated from the cover core 2; during installation, the boss 15 is aligned with the connecting holes 11 on the left and right side walls of the groove 21, and the two ends of the telescopic member 16 are inserted into the connecting holes 11 to complete the installation.

[0030] In order to make the upper cover 1 more convenient to open, a torsion spring 14 is provided in the through hole of the boss 15. When the upper cover 1 is opened, the torsion spring 14 can provide an automatic pop-up force. A connecting block 13 is provided between the torsion spring 14 and the groove 21 of the upper cover 1. The connecting block 13 is provided with a boss 13a and a convex portion 13b inserted into the through hole of the boss 15. The side where the groove 21 of the upper cover 1 is in contact with the connecting block 13 is provided with an embedding groove 12 for the connecting block 13 to be installed. Specifically, when the connecting block 13 is set in the embedding groove 12, the convex portion 13b is in contact with the embedding groove 12, so that the connecting block 13 drives the upper cover 1 to rotate at the same time. The boss 13a is sleeved on the torsion spring 14 in the through hole, which plays the role of transmitting the elastic force of the torsion spring 14, ensuring that the elastic force of the torsion spring 14 can be effectively transmitted to the upper cover 1, and when the user opens the upper cover 1, the upper cover 1 is popped out.

[0031] like Figure 4As shown, a suction nozzle 17 extending into the cup body 5 is provided in the lid core 2. The suction nozzle 17 has an outwardly extending abutment portion 17b and a pressure relief hole 17c is provided on the abutment portion 17b for balancing the air pressure inside and outside the cup body 5. When the temperature inside the cup body 5 changes or the air pressure changes due to other reasons, the pressure relief hole 17c can balance the air pressure inside and outside the cup body 5, preventing the cup lid from being difficult to open and making it easier for users to drink water.

[0032] The cover core 2 is provided with a sealing cover 8 for the suction nozzle 17 to pass through. The bottom of the sealing cover 8 is provided with a mounting hole 19 for limiting the suction nozzle 17. An air hole 10 corresponding to the suction nozzle 17 is provided in the mounting hole 19. The suction nozzle 17 is provided with a limiting groove 17a. The sealing cover 8 is provided with a protrusion 8b at the opening for the suction nozzle 17 to pass through. When the protrusion 8b is inserted into the limiting groove 17a on the suction nozzle 17, and the suction nozzle 17 is embedded in the mounting hole 19 at the bottom of the sealing cover 8, and the pressure relief hole 17c is inserted into the air hole 10, the position of the suction nozzle 17 on the sealing cover 8 is positioned.

[0033] The sealing cover 8 is provided with a soft protrusion 8a for locating the installation position of the sealing cover 8. The cover core 2 is provided with a recessed portion 18, and the protrusion 8a is arranged in the recessed portion 18, which makes it convenient for the user to remove the sealing cover 8 and also makes it convenient for the user to accurately locate the installation position of the sealing cover 8 on the cover core 2.

[0034] A sealing member is sleeved on the sealing cover 8. Preferably, the sealing member is an elastic sealing ring 9. One side of the elastic sealing ring 9 rests on the sealing cover 8, and the other side rests on the top of the cup body 5. The extrusion effect generated by the threaded connection and tightening of the connector 3 and the cup body 5 enables the elastic sealing ring 9 to play a good sealing role to prevent the liquid in the cup from leaking. A protrusion extending inward is provided on the inner ring of the elastic sealing ring 9. When the suction nozzle 17 is embedded in the mounting hole 19 of the sealing cover 8, the elastic sealing ring 9 is sleeved on the sealing cover 8. The protrusion on the inner ring of the elastic sealing ring 9 and the abutting portion 17b on the suction nozzle 17 are in contact with each other, which locates the installation position of the elastic sealing ring 9 on the cover core 2 and also enhances the stability of the suction nozzle 17 installed on the sealing cover 8.

[0035] like Figure 6 、 Figure 7 As shown, a plurality of vertically extending soft stop ribs 20 are provided on the inner side wall of the cover core 2. The stop rib 20 is wavy and has a sunken end 20a and an upper convex end 20c. A guide slope 20b is provided between the sunken end 20a and the upper convex end 20c. The sealing cover 8 is embedded in the cover core 2 and clamped by the stop rib 20. During installation, the sealing cover 8 slides from the upper convex end 20c into the sunken end 20a via the guide slope 20b, thereby realizing rapid installation and fixation of the sealing cover 8.

[0036] like Figure 2As shown, a first locking hook 6 is provided on the upper cover 1, and a second locking hook 7 is provided on the cover core 2. The first locking hook 6 and the second locking hook 7 are engaged to close the cup cover, ensuring that the cup cover will not be accidentally opened during carrying and use, thereby improving the safety of the thermos cup.

[0037] When the user needs to remove the cup cover, the user presses or uses other means to make the retractable ends of the telescopic part 16 retract toward the boss 15, and remove the upper cover 1 from the boss 15 of the cover core 2. After removal, the connecting block 13 inserted in the boss 15 can be taken out from the boss 15 of the cover core 2, and the cup body 5 and the connecting part 3 are unscrewed in turn. After unscrewing, the elastic sealing ring 9 is no longer pressed against the top of the cup body 5. After removing the elastic sealing ring 9, the soft protrusion 8a on the sealing cover 8 is moved in the recessed part 18 of the cover core 2, and the sealing cover 8 is removed from the bottom of the cover core 2. After removal, the limiting groove 17a of the suction nozzle 17 is squeezed to disengage the limiting groove 17a from the protrusion 8b at the opening of the sealing cover 8, and the suction nozzle 17 is removed from the mounting hole 19 at the bottom of the sealing cover 8. After removal, the removed parts are cleaned.
