Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of daily necessities, in particular to a cup cover of a vacuum cup and the vacuum cup. BACKGROUND

[0002] The vacuum cup is a cup which can delay the heat dissipation of the liquid in the inner container through the vacuum layer between the inner container and the cup body, so as to achieve the purpose of heat preservation. Although the existing vacuum cup can meet the heat preservation function of the liquid in the cup, the good heat preservation effect makes the water temperature unable to be quickly reduced, so that people cannot drink freely. Therefore, the inventor designs a direct drinking vacuum cup, which is provided with a cup sleeve on the cup body to form a cavity between the cup body and the cup sleeve, and a lower water outlet hole is arranged at the bottom of the cup body to communicate with the cavity, so that the water in the vacuum cup can flow into the cavity through the lower water outlet hole, and the heat dissipation is realized by the cup sleeve, and the drinking is realized through the cup mouth of the cup sleeve. At the same time, in order to avoid the water in the cup body from flowing out when the water is drunk from the cup sleeve outlet, a cup cover is further arranged at the water inlet of the cup body.

[0003] In order to make the water in the vacuum cavity and the water in the cavity between the cup body and the cup sleeve flow out from the same outlet, the inventor further designs a cup cover which can be covered on the vacuum cup and the cup sleeve at the same time, and a bounce switch valve matched with the vacuum cup and a hole communicated with the inner cavity of the cup sleeve are arranged on the cup cover. When the bounce switch valve is opened, the water in the vacuum cup can be poured out through the switch valve, and when the switch valve is closed, the water in the inner cavity of the cup sleeve can be poured out through the hole on the cup cover after heat exchange. However, when the user forgets to close the bounce switch valve during use, the user directly drinks the beverage in the cup sleeve after heat exchange, which may cause the beverage in the vacuum cavity to flow out directly, causing the situation of scalding or frostbite. SUMMARY

[0004] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present application is to provide a cup cover of a vacuum cup and a vacuum cup which have a clever structure design and are beneficial to improve the safety in use.

[0005] In order to solve the above-mentioned technical problems, the present application adopts the following technical solutions:

[0006] The cup cover of the vacuum cup is characterized in that a main cover body is in a whole cylindrical shape, the main cover body comprises a cup cover wall in a cylindrical shape, the cup cover wall is provided with a first sealing part for sealing an inner cup opening and a second sealing part for sealing an outer cup opening in sequence from inside to outside, the first sealing part and / or the second sealing part is further provided with a mounting thread, the cup cover wall is further provided with a water passing hole located in a region between the first sealing part and the second sealing part, a valve seat in a cylindrical shape is coaxially arranged in the cup cover wall, a valve rod is arranged on a bore of the valve seat, the valve rod is provided with a sealing element for sealing the valve seat, and the valve rod and the valve seat are provided with a reset elastic element arranged in compression, so that the sealing element is sealingly matched on the valve seat in a direction towards an outer end.

[0007] With the above structure, when in use, the cup cover is assembled on a matched vacuum cup, if a user wants to use high-temperature or low-temperature drinks in the inner cup opening, the cup cover can be directly opened, and the high-temperature or low-temperature drinks can be poured out. If the user wants to drink the drinks after heat exchange in the cup sleeve, the valve rod can be pressed down first, so that the inner cup opening (the cup body) and the air outside are communicated through the valve seat, the vacuum drinks flow into the cup sleeve, and the drinks are heat exchanged with the cup sleeve in the cup sleeve. When drinking, the user must not keep pressing the valve rod, the valve rod drives the sealing element to seal the valve seat under the action of the reset elastic element, so that when the heat exchanged drinks in the cup sleeve are drunk, the vacuum drinks cannot be directly poured out from the inner cup opening, and the safety of use is improved.

[0008] The valve rod is connected with a first magnet, further comprising a second magnet provided in the same pole and opposite to the first magnet, the second magnet is located outside the main cover body and can move towards the first magnet, so that the first magnet drives the valve rod to push the sealing element to open the valve seat.

If the user wants to use the high-temperature or low-temperature beverage in the first cavity, the cup cover can be directly opened, and the high-temperature or low-temperature beverage can be poured out. If the user wants to drink the beverage after heat exchange through the second cavity (the cup sleeve), the valve rod can be pressed first, so that the first cavity (the cup body) and the air outside are communicated through the valve seat. At this time, the air pressure in the first cavity and the second cavity is consistent, according to the principle of the communicating vessel, the heat preservation beverage in the first cavity flows into the second cavity from the lower water outlet, and the beverage in the second cavity exchanges heat with the cup sleeve. When drinking, the user must not keep pressing the valve rod, and the valve rod drives the sealing element to seal the valve seat under the action of the reset elastic element, so that the heat preservation beverage in the first cavity cannot be directly poured out when the heat exchange beverage in the second cavity is drunk, thereby improving the safety of use. In addition, since the valve seat is sealed by the sealing element, the first cavity is isolated from the outside air, and the internal air pressure cannot be kept higher than or equal to the external air pressure, so that the beverage in the first cavity cannot flow into the second cavity from the lower water outlet.
