[0019] Beneficial effects

[0020] The utility model provides a vacuum insulation cup. Compared with the existing technology, it has the following advantages:

[0021] 1. For this vacuum insulation cup, when the piston moves downward, the air inside the double-layer cup body can be sucked into the vacuum cylinder through the first micro-check one-way valve. When the piston moves upward, the air inside the vacuum cylinder is discharged through the second micro-check one-way valve, thereby realizing that the air inside the side wall of the double-layer cup body is sucked out by the piston. After the air is sucked out, the side wall of the double-layer cup body is in a vacuum state, so that the cup has a heat preservation effect, thereby realizing the switch between an ordinary cup and a thermos cup.

[0022] 2. The vacuum insulated cup moves downward while the screw rotates, and the sealing plug moves downward at the same time. When the sealing plug moves downward and crosses the connecting groove, the outside world is connected to the side wall of the double-layer cup body through the connecting groove and the connecting ring, so that the outside air can directly enter the double-layer cup body. The double-layer cup body that enters the air no longer has the insulation effect, thereby realizing the switch between the thermos cup and the ordinary cup. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] The present application will be further described in detail below through the accompanying drawings and examples.

[0031] Reference Figures 1 to 4 , the embodiment of the present application provides a vacuum insulation cup, including a double-layer cup body 1, an auxiliary cylinder 4 is fixedly installed at the bottom of the double-layer cup body 1, an internal groove 7 is opened inside the auxiliary cylinder 4, and an air extraction component 2 and an air release component 3 are arranged inside the internal groove 7, and the air extraction component 2 includes an air extraction cylinder 21, which is fixedly installed on the inner top of the internal groove 7, and a first micro-check one-way valve 27 is fixedly installed between the top wall of the air extraction cylinder 21 and the double-layer cup body 1, the first micro-check one-way valve 27 connects the interior of the side wall of the double-layer cup body 1 and the interior of the air extraction cylinder 21, and a second micro-check one-way valve 28 is fixedly installed on the side wall of the air extraction cylinder 21, and the second micro-check one-way valve 28 connects the interior of the air extraction cylinder 21 with the outside world, and a piston 24 is slidably connected to the interior of the air extraction cylinder 21, and a pull rod 25 is fixedly installed at the bottom of the piston 24, and a pull plate 26 is fixedly installed at the bottom of the pull rod 25, and the pull plate 26 is located below the air extraction cylinder 21. An external threaded barrel 6 is screwed onto the side wall of the internal groove 7 , and a bottom plate 5 is fixedly mounted on the bottom of the external threaded barrel 6 . The bottom plate 5 is located at the bottom of the auxiliary barrel 4 .

[0032] A first limiting ring 22 and a second limiting rod 23 are fixedly installed inside the vacuum cylinder 21. The second limiting rod 23 is located inside the bottom opening of the vacuum cylinder 21. The first limiting ring 22 is fixedly installed between the second micro check valve 28 and the piston 24.

[0033] The communication direction of the first micro-check one-way valve 27 is from the inside of the side wall of the double-layer cup body 1 to the inside of the air pump 21 , and the communication direction of the second micro-check one-way valve 28 is from the inside of the air pump 21 to the outside.

[0034] In this embodiment, when the side wall of the double-layer cup body 1 is filled with air, the cup as a whole is an ordinary cup, and heat can quickly pass through the double-layer cup body 1, so that the whole cup has no heat preservation effect. When heat preservation is needed, the bottom plate 5 and the external threaded tube 6 can be rotated to move the bottom plate 5 out from the bottom of the internal groove 7. After moving out, the piston 24 can be pulled up and down by the pull plate 26 and the pull rod 25. When the piston 24 moves down, the air inside the double-layer cup body 1 can be sucked into the air pump 21 through the first micro-check one-way valve 27. When the piston 24 moves up, the air inside the air pump 21 is discharged through the second micro-check one-way valve 28, thereby realizing that the air inside the side wall of the double-layer cup body 1 is sucked out by the piston 24. After the air is sucked out, the side wall of the double-layer cup body 1 is in a vacuum state, so that the cup has a heat preservation effect, thereby realizing the switch between an ordinary cup and a thermos cup.

[0035] Reference Figures 1 to 4 In one aspect of this embodiment, the deflation assembly 3 includes a deflation cylinder 32, which is fixedly installed on the inner top of the internal groove 7. A connecting ring 31 is fixedly installed between the top of the deflation cylinder 32 and the double-layer cup body 1. The connecting ring 31 connects the side wall of the double-layer cup body 1 and the interior of the deflation cylinder 32. A sealing plug 34 is inserted into the interior of the deflation cylinder 32 and below the connecting ring 31.

[0036] An internally threaded barrel 36 is fixedly mounted below the inner sidewall of the bleed cylinder 32. A screw 35 is threadedly connected to the interior of the internally threaded barrel 36. The top wall of the screw 35 abuts against the bottom of the sealing plug 34. A knob 37 is fixedly mounted below the bottom of the screw 35 and below the bleed cylinder 32. A connecting groove 33 is formed in the sidewall of the bleed cylinder 32. The connecting groove 33 is located below the sealing plug 34 and above the internally threaded barrel 36.

[0037] In this embodiment, the screw 35 is driven to rotate by rotating the knob 37. Under the action of the internal threaded cylinder 36, the screw 35 can move up and down while rotating. The upward movement of the screw 35 can squeeze the sealing plug 34. After being squeezed, the edge of the sealing plug 34 can spread to the surroundings and fit tightly against the inside of the bleed cylinder 32, thereby improving the sealing performance of the sealing plug 34. When the screw 35 moves downward, the sealing plug 34 returns to its original state. The diameter of the sealing plug 34 is slightly smaller than the inner diameter of the bleed cylinder 32, so it is sealed under the action of gravity. The sealing plug 34 can move downward synchronously; when the cup needs to be switched from the heat preservation state to the normal state, the screw 35 is rotated and moved downward at the same time. When the screw 35 moves downward, the sealing plug 34 moves downward. When the sealing plug 34 moves downward and crosses the connecting groove 33, the outside world is connected with the side wall of the double-layer cup body 1 through the connecting groove 33 and the connecting ring 31, so that the outside air can directly enter the double-layer cup body 1. The double-layer cup body 1 that enters the air no longer has the heat preservation effect, thereby realizing the switching between the heat preservation cup and the normal cup.

[0038] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0039] Working principle: When the side wall of the double-layer cup body 1 is filled with air, the cup as a whole is an ordinary cup, and heat can quickly pass through the double-layer cup body 1, making the cup as a whole have no heat preservation effect. When heat preservation is needed, the bottom plate 5 and the external threaded tube 6 can be rotated to remove the bottom plate 5 from the bottom of the internal groove 7. After removal, the piston 24 can be pulled up and down by the pull plate 26 and the pull rod 25. When the piston 24 moves down, the air inside the double-layer cup body 1 can be pumped into the air pump 21 through the first micro-check one-way valve 27. When the piston 24 moves up, the air inside the air pump 21 is discharged through the second micro-check one-way valve 28, thereby realizing the air inside the side wall of the double-layer cup body 1 being pumped out by the piston 24. After pumping, the side wall of the double-layer cup body 1 is in a vacuum state, which makes the cup have a heat preservation effect, thereby realizing the difference between an ordinary cup and a thermos cup. Switching; when the side wall of the double-layer cup body 1 is filled with air, the cup as a whole is an ordinary cup, and heat can quickly pass through the double-layer cup body 1, so that the whole cup has no heat preservation effect. When heat preservation is needed, the bottom plate 5 and the external threaded tube 6 can be rotated to move the bottom plate 5 out from the bottom of the internal groove 7. After moving out, the piston 24 can be pulled up and down by the pull plate 26 and the pull rod 25. When the piston 24 moves down, the air inside the double-layer cup body 1 can be sucked into the air pump 21 through the first micro-check one-way valve 27. When the piston 24 moves up, the air inside the air pump 21 is discharged through the second micro-check one-way valve 28, thereby realizing that the air inside the side wall of the double-layer cup body 1 is sucked out by the piston 24. After the air is sucked out, the side wall of the double-layer cup body 1 is in a vacuum state, so that the cup has a heat preservation effect, thereby realizing the switching between an ordinary cup and a thermos cup.
