         2 . The sealed container according to  claim 1 , wherein a pulling portion passes through the lid body to the upper side of the container lid is disposed on the upper side of the movable base, the twisting switch is movably connected with the pulling portion, the pulling portion is provided with twisting grooves on both sides, the twisting switch is movably connected with the pulling portion at the twisting groove, and the twisting switch and the pulling portion adapt to be stably and movably connected under an action of an elastic force of the twisting grooves of the pulling portion and the elastic seal. 
     
     
         3 . The sealed container according to  claim 2 , wherein a limit portion is disposed on the upper side of the lid body, wherein when the sliding cover slides on the twisting switch, the sliding cover is abutted to or separated from the limit portion; when the sliding cover is abutted to the limit portion, the sliding cover cannot be twisted, so that the twisting switch also cannot be twisted; and when the sliding cover is separated from the limit portion, the sliding cover and the twisting switch adapt to be twisted together. 
     
     
         4 . The sealed container according to  claim 2 , wherein a notch is disposed at a lower end of the twisting switch, the twisting switch adapt to be attached to and detached from the pulling portion at the notch, wherein when the sliding cover slides on the twisting switch, the sliding cover covers the notch or exposes the notch, so that the sliding cover forms a disassembly safety portion at the notch and limits movement between the twisting switch and the pulling portion; when the sliding cover slides to expose the notch, the twisting switch and the sliding cover adapt to be attached to/detached from the pulling portion together; and when the sliding cover slides until the notch is covered, neither the twisting switch nor the sliding cover adapt to be attached to and detached from the pulling portion. 
     
     
         5 . The sealed container according to  claim 2 , wherein a positioning buckle is disposed between the sliding cover and the twisting switch for snapping and positioning the sliding cover and the twisting switch. 
     
     
         6 . The sealed container according to  claim 5 , wherein the positioning buckle includes positioning grooves on both sides of the twisting switch, and positioning protrusions are disposed on both sides of the sliding cover, wherein during the sliding of the sliding cover, the positioning protrusions of the sliding cover are snapped in the positioning grooves. 
     
     
         7 . The sealed container according to  claim 2 , wherein a vent hole is disposed in the movable base, and the vent hole extends to the upper side of the lid body through the pulling portion; an elastic sealing plug is disposed on the upper side of the vent hole, and a sealing hole communicated with the vent hole is disposed in the middle of the elastic sealing plug, and the sealing hole is opened or closed under the sliding action of the sliding cover. 
     
     
         8 . The sealed container according to  claim 1 , wherein the elastic seal has an N-layer structure, and when the container is sealed and connected with the container lid, the sealing portion formed by the elastic seal has an N-layer structure. 
     
     
         9 . The sealed container according to  claim 7 , wherein the elastic seal is fixedly connected or removably connected with the movable base or the lid body. 
     
     
         10 . The sealed container according to  claim 8 , wherein the elastic seal has a ring structure, and an upper end of the elastic seal is connected with the lid body, and a lower end is located on the upper side of the movable base, wherein when the movable base is moved upward, the movable base squeezes the elastic seal outward at a position of the maximum diameter of the deformed part, the elastic seal is squeezed at the maximum diameter beyond the movable base at the position of the maximum diameter of the deformed part, and the maximum diameter of the deformed part of the squeezed elastic seal is greater than the diameter of the sealing part of the container, thereby preventing the movable base from continuing to move upward, so that the movable base presses the elastic seal on the neck portion of the container to form a sealing portion, and realizing the sealing of the container lid and the container; and when the lower end of the elastic seal is separated from the movable base, under the elasticity of the elastic seal itself, the elastic seal recovers from deformation and releases the sealing state. 
     
     
         11 . The sealed container according to  claim 8 , wherein the elastic seal has a ring-like structure with a hole in the middle part, a protrusion portion is disposed between the hole and the edge of the elastic seal, and the elastic seal is connected to the movable base or the lid body through the middle opening, wherein when the movable base is moved upward, the movable base moves towards the lid body, and under the squeezing action of the movable base and the lid body, the elastic seal expands outward, the edge of the elastic seal extends beyond the movable base to be greater than the diameter of the sealing part of the container to prevent the movable base from continuing to move upward, so that the movable base presses the elastic seal on the neck portion of the container to form a sealing portion, and to realize the sealing of the container lid and container. 
     
     
         12 . The sealed container according to  claim 11 , wherein a pressing plate is disposed on the lower side of the lid body, wherein when the movable base is moved upward, the lower side of the pressing plate is abutted to the upper side of the elastic seal, and the lower side of the elastic seal is abutted to the upper side of the movable base, so that the elastic seal is deformed, the edge of the elastic seal extends outward beyond the movable base; and when the lower end of the elastic seal is separated from the movable base, under the elasticity of the elastic seal itself, the elastic seal recovers from deformation, and the sealing is released. 
     
     
         13 . The sealed container according to  claim 3 , wherein a positioning buckle is disposed between the sliding cover and the twisting switch for snapping and positioning the sliding cover and the twisting switch. 
     
     
         14 . The sealed container according to  claim 4 , wherein a positioning buckle is disposed between the sliding cover and the twisting switch for snapping and positioning the sliding cover and the twisting switch.
