As an embodiment of the present invention, the annular disc 61 is connected to the inner wall of the second annular groove 6 in a sealing and sliding manner; the outer side wall of the bottom end of the lower cup cover 13 is provided with two symmetrically distributed anti-falling grooves; a first cavity 62 is formed in the lower cup cover 13; a first push plate 63 is connected to the inner wall of the first cavity 62 in a sealing and sliding manner; the first push plate 63 is fixedly connected to the side wall of the first cavity 62 through a spring; a first push rod 64 is fixedly connected to the side wall of the first push plate 63 far away from the second annular groove 6; the side wall of the first push rod 64 far away from the first push plate 63 extends into the anti-falling groove, and is fixedly connected with an anti-falling block 65; the second annular groove 6 is communicated with the first cavity 62 through a second hose; when the vacuum cup is in operation, when the vacuum cup is placed on a table top, the vacuum cup is prone to toppling, the annular disc 61 arranged in the vacuum cup slides in the second annular groove 6 in a sealing mode, under the action of the gravity of the vacuum cup, the annular disc 61 is extruded into the second annular groove 6, extruded gas enters the first cavity 62 from the second hose, the gas can push the first push plate 63 to move, the first push plate 63 moves to drive the anti-falling block 65 to move through the first push rod 64, after the annular disc 61 completely enters the second annular groove 6, the anti-falling block 65 extends out at the moment, the bottom end of the anti-falling block 65 contacts with the table top, the whole vacuum cup is further protected and supported, the vacuum cup is not prone to toppling, after the vacuum cup is taken away from the table top, the annular disc 61 and the first push plate 63 can return to the original position under the action of elastic force, and the anti-falling block 65 is guaranteed not to influence taking of the vacuum.

As an embodiment of the present invention, a third annular groove 7 is formed on the outer side wall of the cup body 1; a rubber layer 71 is fixedly connected to the side wall of the third annular groove 7; a pair of first pressing plates 72 which are symmetrically distributed is fixedly connected to the side wall of the third annular groove 7 through a spring; a second push rod 73 is fixedly connected to the side wall of the first pressure plate 72 far away from the rubber layer 71; the end part of the second push rod 73 far away from the first press plate 72 extends into the vacuum cavity and is fixedly connected with a heat-conducting silica gel pad 74; when the thermal cup is in operation, when people hold the thermal cup by hands, the temperature of the outer surface of the thermal cup is low, the hands are easy to freeze, and the phenomenon that the hands fall off from the hands is easy to occur.

The working principle is as follows: when the tea cup is in operation, firstly, tea leaves are put into the opening of the second filter cylinder 16 on the lower cup cover 13, the barrel cover 51 is connected to the opening of the first filter cylinder 14 through threads, when the lower cup cover 13 is installed, the second fixing column 33 is put into the second groove 3, the position of the fixing block 15 is fixed, when the lower cup cover 13 is connected to the cup body 1 through threads, because the outer diameter of the opening of the second filter cylinder 16 is the same as the inner diameter of the first filter cylinder 14, when the lower cup cover 13 is installed, the first filter cylinder 14 is put into the second filter cylinder 16, when the lower cup cover 13 is rotated, the first filter cylinder 14 enters the second filter cylinder 16, the first filter cylinder 14 is driven to rotate through the rotating column 22 through the rotating block 23, the first water through hole 141 is communicated with the second water through hole 161, then boiled water is injected into the opening of the cup body 1 to soak the tea leaves, when the tea water is suitable for taste, the cup body 1 can be reversed, at the moment, boiled water flows out from the first filter cylinder 14, the first water through hole 141 and the second water through hole 161 are in a staggered state by rotating the rotating block 23, at the moment, water flow cannot enter the first filter cylinder 14 and tea leaves cannot be continuously soaked in the cup body 1, the taste of the tea leaves is kept to be suitable for the taste all the time, the tea leaves are not soaked in the boiled water any more, when the tea leaves need to be soaked again, the first water through hole 141 and the second water through hole 161 are processed and communicated by the rotating component 2, and the tea leaves are enabled to be soaked again; when the vacuum cup works, the annular disc 61 arranged in the vacuum cup sealing sliding device is sealed and slides in the second annular groove 6, under the action of the gravity of the vacuum cup, the annular disc 61 is extruded to enter the second annular groove 6, the extrusion gas enters the first cavity 62 from the second hose, the gas can push the first push plate 63 to move, the first push plate 63 moves to drive the anti-falling block 65 to move through the first push rod 64, after the annular disc 61 completely enters the second annular groove 6, the anti-falling block 65 extends out at the moment, the bottom end of the anti-falling block contacts with a table top, the whole vacuum cup is further protected and supported, the vacuum cup is not prone to toppling, after the vacuum cup is taken away from the table top, the annular disc 61 and the first push plate 63 can return to the original position under the action of elastic force, and the anti-falling block 65 cannot influence taking of the vacuum cup and dismounting of the lower cup cover.
