Description

A kind of sealed cup cover
Technical field
The utility model relates to a kind of sealed cup cover.
Background technology
Current, because the rhythm of life ratio is very fast, majority like carrying water tumbler, and this just requires the good airproof performance of cup, can not leak, so the cup of good sealing effect has been subjected to consumer's favor.But existing cup or vacuum bottle are in use, especially after adding the higher water of temperature or other liquid, when water that adds or fluid temperature reduction, can produce certain negative pressure in cup or in the bottle, cause bowl cover to be not easy to open, brought inconvenience for normal the use.
The utility model content
The purpose of this utility model provides a kind of sealed cup cover, when producing negative pressure in the cup, can be relatively easy to open cup.
For achieving the above object, the technical solution adopted in the utility model is: a kind of sealed cup cover, comprise bowl cover, described bowl cover top has the hole, in this hole pressure relief device is housed, this pressure relief device comprises the pressure release body of stepped cylindrical or truncated cone-shaped, and the end that this pressure release body cross section is little stretches out from described hole, pressure release body top is provided with fastening cover, by fastening cover the pressure release body is fixed on the bowl cover; Be provided with cavity in this pressure release body, the bottom of this cavity is provided with relief hole, and this fastening cover top is provided with air pressure retaining hole and the diameter centre bore less than cavity diameter, and this air pressure retaining hole and centre bore and described cavity connect; In the pressure release body cavity relief valve is housed, this relief valve comprises valve body and handle, and this valve body is a cylinder, and relief hole is opened and closed to the center bore inner wall on itself and fastening cover top by threaded engagement by rotary handle.
In the scheme that the utility model adopts owing on bowl cover, adopted pressure relief device, when in cup, producing negative pressure, realize opening relief hole by rotary handle, the air pressure retaining hole and cup interior air pressure maintenance balance of gas by being arranged on pressure release body top, eliminate the negative pressure in the cup rapidly, make that opening bowl cover is easy to; The sealing bowl cover is widely used in sealing on teacup and the vacuum bottle.
Description of drawings
Fig. 1 is the profilograph of the utility model sealed cup cover.
The specific embodiment
As shown in Figure 1, sealed cup cover of the present utility model comprises bowl cover 1, be provided with the hole on the top of bowl cover, the pressure relief device that is made of pressure release body 2 and relief valve 3 is housed in this hole, pressure release body 2 is stepped cylinder or Rotary-table, inside is provided with cylindrical cavity, and the cavity bottom is provided with relief hole 5; The cross-sectional diameter of this pressure release body bottom is greater than the cross section of its upper end and the cross-sectional diameter of bowl cover topped hole, and stretch out the hole from bowl cover the upper end, and this extension outer circle wall is provided with external screw thread; This pressure release body top is provided with fastening cover 9, fastening cover 9 sidewall inner peripheral surfaces are provided with the internal thread that matches with external screw thread on the external periphery of pressure release, fastening cover 9 excircle diameters are fixed on the pressure release body on the bowl cover 1 by fastening cover 9 greater than the diameter of described bowl cover 1 topped hole; These fastening cover 9 tops have centre bore, and the inwall of described centre bore is provided with internal thread; Depart from central hole on the fastening cover top and be provided with air pressure retaining hole 6, air pressure retaining hole 6 also can be pressed close to centre bore certainly, as long as can guarantee the air pressure and the atmospheric pressure balance of pressure release body 2 internal cavities; For guaranteeing result of use, will there be certain thickness on the top of this fastening cover 9.Pressure release body 2 bottoms and bowl cover contact portion can be equipped with sealing gasket 8, and sealing pad 8 can be softer rubber of material or plastic mattress; Relief valve comprises valve body 3, this valve body 3 can be cylindrical rubber body or the plastic body of diameter greater than relief hole 5, its outer circumference surface is provided with the external screw thread that matches with internal thread on the center bore inner wall of fastening cover top, relief valve is fixed on the pressure release body by this screw thread, relief valve is provided with handle 4, by rotary handle 4, the relief hole 5 on the pressure release body bottom is closed and opened to the driving valve body, and relief valve bottom and relief hole contact portion are equipped with the softer sealing gasket of material 7.When needs were eliminated the negative pressure of cup, rotary handle 4 made valve body leave the relief hole 5 of pressure release body bottom, makes the Pneumatic pipe cleaner in the cup cross relief hole 5 and air pressure retaining hole 6 pressure release rapidly; When not needing pressure release, turn handle 4 makes valve body 3 closely contact with the relief hole 5 of pressure release body 2 low sides, reaches the effect of sealing.
In the above-described embodiment, fastening cover 9 also can be realized by the mode of clamping pressure release body 2 is fixed on the bowl cover 1 with the pressure release body, be that fastening cover 9 sidewall inner peripheral surfaces are provided with projection, pressure release body 2 stretches out bowl cover 1 part and is provided with the pit that matches with described projection with fastening cover 9 contact portions.
New novel being mainly used in the sealing teacup of this practicality, on the vacuum bottle, the scope of application is just wider in the winter time.
