Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides Figure 1-3 A leak-proof base for a thermos, comprising:

[0024] A thermos shell 1, with a handle 2 fixedly connected to one side of the thermos shell 1;

[0025] The base 3 is threadedly connected to the external thread on the bottom surface of the thermos shell 1 through an internal thread. The thermos shell 1 is provided with an inner liner 4 and the bottom of the inner liner 4 is provided with an arc-shaped bottom pad 5 for supporting the inner liner 4. The bottom of the arc-shaped bottom pad 5 is connected to the base 3. The base 3 is provided with a water collecting component for collecting the water remaining on the surface of the thermos shell 1. The residual water after pouring out the inner liner 4 through the bottle mouth 6 of the water collecting component leaks into the water collecting tank 8 of the base 3 through the water collecting channel 7, so that the water in the water collecting tank 8 is collected under the sealing of the seal 9 and the seal 9 is opened to discharge the collected water into the base 3.

[0026] The water collection assembly includes a branch pipe 10 and a drain pipe 11. The bottle mouth 6 is connected to the top of the thermos shell 1. The water collection channel 7 is arranged between the thermos shell 1 and the inner tank 4. The branch pipe 10 is provided in several groups, and one end of the several groups of branch pipes 10 is connected to the water collection tank 8, and the other end is connected to the drain pipe 11 in the base 3.

[0027] The plug 9 is sealed at one end of the drain pipe 11 , and a drainage channel 12 is provided in the middle of the arc-shaped bottom pad 5 , and one end of the drainage channel 12 is communicated with the water collecting tank 8 .

[0028] A filter screen 13 for filtering water leaking into the water collection tank 8 is detachably provided at the connection between the top of the inner liner 4 and the thermos shell 1. The filter screen 13 is fixed to the connection between the inner liner 4 and the thermos shell 1 by a snap-fit ​​connection, which can be conveniently disassembled and cleaned later. The water leaking into the water collection channel 7 is filtered by the filter screen 13 to prevent impurities from entering the drain pipe 11 and causing blockage, and the water collection channel 7 can also be protected to prevent debris from falling into it.

[0029] A bottle stopper 14 is inserted into the bottle mouth of the inner liner 4 , and the bottle stopper 14 is tightly combined with the bottle mouth of the inner liner 4 to prevent hot water from leaking out of the bottle mouth of the inner liner 4 .

[0030] A plug rack 15 is provided in the base 3, a sealing opening 16 is provided in the middle of the plug rack 15 and a sealing ring 17 is provided on the surface of the sealing opening 16, one end of the drain pipe 11 is connected to the sealing opening 16, and the sealing ring 17 can enhance the sealing performance when the sealing column 19 is inserted into the slot 20.

[0031] Elastic card blocks 18 are connected inside the plug rack 15 and on both sides of the sealing port 16. A sealing column 19 is provided in the middle of the plug 9 and the sealing column 19 is inserted into the sealing port 16 to seal the sealing port 16. Slots 20 are provided inside the plug 9 and on both sides of the sealing column 19. After the elastic card blocks 18 are inserted into the slots 20, they are engaged with the card grooves 21 provided in the plug 9. The two groups of elastic card blocks 18 can clamp and fix the plug 9 into the plug rack 15, thereby preventing the plug 9 from loosening due to accidental touch and causing water leakage.

[0032] The leak-proof base of the thermos can be used to pour out the hot water by lifting the handle 2 to tilt the inner liner 4. After the inner liner 4 is straightened, the water that does not enter the inner liner 4 will flow into the water collection channel 7 along the inner wall of the bottle mouth 6, and flow along the inner wall of the thermos shell 1 and the outer wall of the inner liner 4 to the water collection tank 8 in the base 3, and be collected by the water collection tank 8, thereby solving the problem of water leakage during the pouring process of the thermos causing the bearing surface of the thermos to become wet. Part of the water that flows along the outer wall of the inner liner 4 into the curved bottom pad 5 can flow into the water collection tank 8 through the drainage channel 12 to be collected, thereby avoiding water accumulation in the curved bottom pad 5.

[0033] After the residual water is collected by the water collecting tank 8 and needs to be drained, a container for collecting water is prepared in advance, and the sealing plug 9 is pulled out from the plug holder 15, so that the sealing column 19 in the middle of the sealing plug 9 is separated from the seal of the sealing opening 16. At this time, the water in the water collecting tank 8 flows into the drain pipe 11 through the branch pipe 10 and flows out through the sealing opening 16 into the container for collecting water, thereby draining the water in the water collecting tank 8 and cleaning the water collected in the base 3 in time.

[0034] When the water in the base 3 is drained, the plug 9 can be inserted into the plug rack 15. When the plug 9 is inserted into the plug rack 15, the two groups of elastic blocks 18 of the plug rack 15 are inserted into the slots 20 of the plug 9. The plug 9 squeezes the two groups of elastic blocks 18 to deform them, so that the two groups of elastic blocks 18 are close to each other. When the elastic blocks 18 come into contact with the card slots 21 under the continuous movement of the plug 9, the elastic blocks 18 rebound and engage with the card slots 21, thereby engaging and fixing the plug 9 into the plug rack 15. At this time, the sealing column 19 is inserted into the sealing port 16 to seal the sealing port 16 to prevent water leakage.
