Anti-suction cup cover of vacuum cup

Technical Field

The utility model belongs to the technical field of the insulated container, a thermos cup prevent suction cup lid is related to.

Background

The vacuum cup is a container made of plastic or stainless steel and vacuum layer, the top of the container is covered tightly, the vacuum heat insulating layer can delay the heat dissipation of the liquid such as water in the container, so as to achieve the purpose of heat preservation. The present thermos cup on the market is equipped with hot water after, covers the bowl cover, and hot water in the thermos cup cools off the back through a period of time, forms the negative pressure because of liquid and gaseous shrink in the cup, leads to the cup lid to be inhaled and hardly can't open even, causes user's inconvenience, influences user's experience, when using great power rotating bowl cover, can make the hot water in the thermos cup spill, causes the scald accident.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problems of the prior vacuum cup and providing the vacuum cup cover with the negative pressure releasing mechanism.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides an anti-suction cup cover of thermos cup, includes outer trim cover and screw cap, the top of screw cap and the inboard roof fixed connection of outer trim cover, the lower extreme department of screw cap is equipped with connecting portion, the periphery of this connecting portion is equipped with the round arch, form round annular installation draw-in groove between this bellied medial surface and the screw cap, installation draw-in groove inside callipers is equipped with the sealing member, its characterized in that, the sealing member include annular body, the lower part downwardly extending of body crosses the bellied annular sealing of arch formation, the lower edge of sealing is buckled to the bowl cover center and is formed the sealed paster, this sealed paster pastes in the laminating face department on the lower extreme terminal surface of connecting portion, it has the through-hole to open on the arch, when the sealed paster separates with the laminating face under the negative pressure, form the first passageway that loses heart between sealed paster and the laminating face and can communicate with the through-hole lower extreme; the body forms the second that can communicate with the through-hole upper end between the deformation back and the installation slot inner wall under the negative pressure effect and loses heart the passageway, and the second loses heart the passageway and communicates with the external world.

Under the normality, the laminating of sealed paster and binding face, the sealed laminating of body and installation slot, the bowl cover is screwed with the rim of a cup cooperation back, and the rim of a cup extrudees the sealing member, makes several sealing connection departments laminating inseparabler, and the first passageway that loses heart and the second of this moment is closed, and perhaps the first passageway that loses heart and the second passageway that loses heart do not form yet. When forming the negative pressure in the cup, the body takes place deformation under the negative pressure effect, and the second loses heart the passageway and forms this moment, and after thin sealed paster separates with the binding face under the negative pressure effect, the passageway that loses heart of the first time forms to make the inside and external atmospheric pressure balance of thermos cup this moment.

In the suction-proof cup cover of the vacuum cup, the sealing patch and the binding surface are mutually attached to form a water sealing rib, the water sealing rib is annular, the cross section of the water sealing rib is triangular, and the bottom and the sealing patch are integrally formed. Annular water sealing muscle makes sealed paster and binding face can effectual laminating when the cooperation to eliminate the clearance, have sealed effectual, effect such as dustproof.

In the anti-suction cup cover of the vacuum cup, the sealing element is made of rubber. The rubber material is compact, not easy to leak, good in adaptability, stability, compressibility and recoverability, good in corrosion resistance and rebound resilience, and long in service life.

In the air suction prevention cup cover of the vacuum cup, the attaching surface is in an inwards concave inclined shape, and the shape of the sealing patch is matched with that of the attaching surface. The inclined binding surface can make the hot air flow enter the second air discharging channel more easily through the first air discharging channel to convect with the cold air flow.

In the bowl cover of breathing in of foretell thermos cup, the air discharge duct has between the bottom surface of body and screw thread lid, the body deformation back, the second of formation loses heart passageway and this air discharge duct intercommunication, and the air discharge duct has external intercommunication all the time.

In the bowl cover of breathing in of foretell thermos cup, mounting groove's tank bottom is the slope form that upper portion leaned out, and the shape of the card income end of body and the shape phase-match of mounting groove tank bottom. The outward inclined angle of the groove bottom is beneficial to the circulation and the discharge of internal gas.

In the air suction prevention cup cover of the vacuum cup, the outer side surface of the threaded cover is provided with an external thread. The cup cover is connected with the cup body in a screwing way through the external thread.

In the suction-proof cup cover of the vacuum cup, the outer edge of the body extends downwards to form a sealing edge, a gap is reserved between the sealing edge and the sealing part, and the sealing edge is embedded into the opening of the cup body and forms side interference sealing with the inner wall of the opening of the handle body.

In the air suction prevention cup cover of the vacuum cup, the outer side surface of the lower part of the sealing edge is inclined inwards. The sealing edge can be inserted into the inner side of the cup mouth conveniently.

Compared with the prior art, the water sealing ribs on the sealing patch effectively enhance the sealing property and the dustproof function of the cup cover; through the slope form design of binding face and the many places of installation slot, can more be favorable to the compressed air volume, the energy of loss hot gas flow can make inside hot gas flow more easily through disappointing passageway and cold air current convection current simultaneously, reduces the atmospheric pressure difference, the difficult problem that current leakproofness drinking cup is difficult to unscrew under the negative pressure is overcome to the customer service, and the leakproofness of the sealing member that keeps that this thermos cup can be better, the life of extension drinking cup.
