Detailed Description

Example 1

As shown in fig. 1 to 8, the entire assembly of a cup (hereinafter, simply referred to as a cup) is called an initial state. When in use, the whole water cup cover 1 is screwed anticlockwise in the initial state (the rotating shaft 5 of the water cup cover 1 passes through the rotating shaft 7 of the sealing round plug cover plate 10 so as to connect the water cup cover 1 with the round plug cover plate 10, the fixed foot 11 of the round plug cover plate 10 is fixed in the fixed foot hole 11-1 of the sealing round plug 24 so as to fix the round plug cover plate 10 with the sealing round plug 24, the left button 14 and the right button 15 are arranged in the button groove 22 of the sealing round plug 24, the fixed hook 16 of the right button 15 hooks the cover edge 3 of the water cup cover 1, namely, the water cup cover 1, the sealing round plug cover plate 10, the sealing round plug 24, the left button 14 and the right button 15 form a whole), the whole water cup cover 1 is unscrewed from the water cup, namely, the threaded opening 23 slowly separates from the threaded opening 44 of the outer sleeve 43, then pouring boiled water from the upper port of the inner container 42, when the boiled water is poured into the inner container 42, the boiled water flows out from the lower water outlet 42-1 of the inner container quickly under the action of gravity, the boiled water flows out from the inner container fixing frame 40 (threads are arranged at the lower end of the inner container fixing frame 40 and can rotate in the inner threads 37 of the base 36, namely, the position of the inner container 42 in the water cup can be adjusted up and down, so that the boiled water flows out from the square hole 41 of the inner container fixing frame is adjusted), and enters the outer sleeve 43, the inner container 42 and the base 36 (because the fixing plug 31 is tightly fixed on the base 36 by the first gasket 30 through the inner threads 37, and the second gasket 35 is arranged between the outer sleeve 43 and the base 36, the boiled water cannot flow out from the water cup) and the water level flowing into the inner sleeve 43, the inner container 42 and the base 36 can be increased continuously along with the continuous increase of the water level in the inner container 42, when a certain height is reached, the sum of the buoyancy of the plug 28 and the elastic force of the third spring 29 is large enough, so that the plug 28 tightly plugs the lower water outlet 42-1 of the inner container 42, the outflow of hot water in the inner container 42 is stopped (because the inner container 42 is not insulated as the outer sleeve 43, the inner container 42 and the base 36, the water in the inner container is cooled quickly, namely cold water is stored quickly), and when the water level of the inner container 42 reaches the maximum value, the water filling is stopped. Then the lower cold water pipe 26 and the lower hot water pipe 25 are respectively inserted into the strip-shaped hole 42-3 of the inner container fixing plate 42-2 and the upper opening of the inner container 42, the first threaded opening 23 of the first sealing round plug 24 is aligned with the second threaded opening 44 of the outer sleeve 43, the whole body just unscrewed is screwed down in the clockwise direction, the upper opening of the inner container 43 is fixed in the inner container opening groove 23-1, hot water in the inner container 43 is prevented from overflowing, and finally the water cup is restored to the initial state. When drinking water is needed by a drinker, the slide lock 16-1 is pushed to the rightmost end from the inside of the sliding groove 16-2, the right button 15 is in an unlocking state, the right button 15 is pressed again, the fixing hook 16 is separated from the cover edge 3 of the first water cup cover 1, under the elastic force of the spring head 6 inserted into the spring head jack 4, the first water cup cover 1 rotates around the first rotating shaft 5 because the first rotating shaft 5 is arranged in the first rotating shaft hole 7, until the first water cup cover 1 is completely opened, the drinker only needs to suck by the sucking pipe 17, and cold water and hot water under the default state are sucked up to be mixed and then enter the sucking pipe 17 to finally enter the mouth of the drinker. If the drinker feels that the water is too hot, the left button 14 arranged in the button groove 22 can be pressed, the front end of the left button 14 presses the hot water pipe 19, so that the water flow from the boiled water in the inner container to the suction pipe 17 through the lower hot water pipe 25, the water flow from the hot water pipe 19 to the suction pipe 17 becomes smaller, the larger the force of pressing the left button 14 is, the smaller the water flow from the cold water pipe 18 is, the water temperature in the suction pipe 17 becomes lower slowly, when the temperature required by the drinker is reached, the force of pressing the left button 14 is kept unchanged, the left button 14 is released after the water is drunk, and the left button 14 returns to the initial state under the elastic force of the left button spring 20. If the drinker feels that the water temperature is too cool, the right button 15 arranged in the button groove 22 can be pressed, the front end of the right button 15 presses the cold water pipe 18, so that the water flow of the cold water stored between the inner container 42 and the outer sleeve 43 and the base 36 reaching the suction pipe 17 through the cold water pipe lower 26 and the cold water pipe upper 18 becomes smaller, the larger the force of pressing the right button 15 is, the smaller the cold water flow is, the hot water flow in the hot water pipe upper 19 is kept unchanged, the water temperature in the suction pipe 17 is gradually increased, when the temperature required by the drinker is reached, the force of pressing the right button 15 is kept unchanged, the right button 15 is released after the water is drunk, and the right button 15 returns to the initial state under the elastic force of the right button spring 21. When the cold water or the hot water is sucked up, the air outside the water cup enters between the inner container 42 and the outer sleeve 43 or in the inner container 42 through the ventilation groove 12-1 of the ventilation valve 12 arranged in the ventilation valve hole 9, so that the space pressure of the cold water or the hot water is consistent with the outside, and a user can drink water more easily. After drinking water is finished, the first cup cover 1 rotates around the first rotating shaft 5, the lower teeth 8 and the upper teeth 2 are slowly close to each other, namely the suction pipe 17 is slowly clamped, finally the cover edge 3 of the first cup cover 1 is hooked by the fixing hook 16 of the right button 15, water in the clamped suction pipe 17 cannot naturally overflow at the moment, and finally the slide lock 16-1 slides from the sliding groove 16-2 to the leftmost end to enable the right button 15 to be locked, and the cup is restored to an initial state at the moment. When the amount of cold water in the water cup is less than a certain threshold value, the sum of the buoyancy provided by the plug 28 and the elastic force of the spring III 29 is insufficient to block the water outlet 42-1 under the liner, and the hot water in the liner 42 naturally flows out to fully supplement the cold water. If the user only wants to drink the hot water as a normal water cup, only needs to store the hot water and does not need to pour the cold water, the pull buckle 34 of the fixed plug 31 is separated from the fixed plug 38 in the initial state of the water cup, and the fixed plug 31 tightly supports the fixed head 32 against the plug 28 under the telescopic action of the telescopic tube 33 of the fixed plug 31, so that the plug 28 cannot slide out of the water outlet 42-1 under the inner container freely, namely the boiled water cannot flow out of the inner container 42, and the function of storing the cold water to provide the cold water is lost. If the user wants to open the function again, the fixing plug 31 is pulled downwards, the pull buckle 34 on the fixing plug 31 is sleeved on the fixing bolt 38 again, and in addition, because one end of the pull rope 13 is fixed in the second rotating shaft 5-1, the user can take the cup by directly holding the pull rope 13 by hand.

Example 2

As shown in fig. 9 to 14, the method and structure of the cup are similar to those of embodiment 1, wherein the functions of the second cup cover 45, the second sealing plug cover 50 and the second sealing plug 52 correspond to the functions of the first cup cover 1, the first sealing plug cover 10 and the first sealing plug 24 in embodiment 1, respectively. The water filling mode is the same as that of the embodiment 1, when the water is filled, after the water cup is restored to the initial state, a user presses the right button 15, so that the fixing hook 16 falls off from the fixing edge 46 of the second water cup cover 45, then the second water cup cover 45 rotates around the third rotating shaft 53 (because the third rotating shaft 53 is clamped in the notch 48 of the sleeve hook 49), the half round head fixing cap 54 on the second sealing round plug 52 is just clamped in the notch 48, the second water cup cover 45 is temporarily fixed, then the water cup is inclined, pouring water into a container prepared in advance is started, if the water is heated too hot, the left button 14 is pressed, the front end of the left button 14 presses the hot water pipe 57, so that the flow rate of hot water is reduced, the flow rate of cold water is unchanged, the cold water enters the cold water pipe 55 through the strip-shaped hole 42-3 of the inner container fixing plate 42-2 between the outer sleeve 43 and the inner container 42, and then enters the water outlet 56 to be converged with the hot water, and finally the water temperature of the poured water is reduced to a proper temperature along with the pressing of the left button 14; if the water temperature is perceived to be too cool, the right button 15 is pressed, the front end of the right button 15 presses the cold water pipe 55 to reduce the flow rate of cold water, and finally the water temperature of the poured water rises to a proper temperature as the pressure of pressing the right button 15 increases. If no proper container can hold water, the newly opened water cup cover II 45 can be pressed from the direction from the rotation shaft III 53 to the pull rope rod 53-1, the sleeve hook 49 can be separated from the rotation shaft III 53, at the moment, the water cup cover II 45 can be used as a container for holding water, and the water cup cover II 45 can be installed on a water cup by reversing operation after the use is finished. After drinking, the second cup cover 45 rotates reversely around the third rotating shaft 53 in the opening direction, so that the original state can be restored, and the round-head soft plug 47 can block the water outlet 56 at the moment so that the cold water and the hot water in the cup cannot overflow freely. When the heat preservation sleeve 43-1 is used in winter, the heat preservation sleeve 43-1 can be sleeved outside the outer sleeve 43 to prevent the cold water from being too low in temperature and prevent the cold water from being frozen and not poured out due to the too low outdoor temperature. Because one end of the pull rope 13 is fixed at the pull rope rod 53-1, a user can take the cup by directly holding the pull rope 13 by hand.

Example 3

In this embodiment, the inner liner 42 in embodiment 1 and embodiment 2 is changed to a metal inner liner 42-1, the inner wall of the metal inner liner 42-1 is an integral metal inner shell 58, the outer shell is divided into an upper part and a lower part, the upper part is a metal outer shell upper 59, the lower part is a metal outer shell lower 61, and a heat insulation sealing material is arranged in the middle: the heat-insulating sealing material III 64, and the upper and lower parts are mutually rotated and screwed together through the threaded port 60, and the heat-insulating sealing material is arranged between the inner wall and the outer wall of the upper port: the first heat-insulating sealing material 62 is also arranged between the inner wall and the outer wall of the lower opening: and a second heat-insulating sealing material 63. After the metal inner container 42-4 is completely installed, air in the inner container is pumped out by using air pumping equipment from the first heat insulation sealing material 62 and the second heat insulation sealing material 63 respectively to the space between the upper inner wall and the lower inner wall and the outer wall, so that the heat preservation effect can be achieved.
