Abstract

The utility model a health-care magnetic cup. A ventilation pressure valve is matched in a central hole of a cup cover, and is composed of a valve body and a valve core. A circular hole guide way is arranged in the valve body, and the valve core is glidingly fitted in the circular hole guide way. Thus, the health-care magnetic cup is easy to open, and is convenient in use.

Description

Insulation magnetic cup with ventilation pressure valve

The utility model relates to a kind of insulation magnetic cup.

At present, totally enclosed thermos cup bowl cover, its weak point is: when in the cup during splendid attire hot water, people get used to bowl cover is screwed, make its sealing and insulation, but treat that the water in the cup temperature descends, liquids and gases just can negative pressure occur because of shrinkage in the cup, cause bowl cover to be sucked and do not open, even can't open.

In view of this, the purpose of this utility model provides a kind of insulation magnetic cup with ventilation pressure valve, and it can make glass interior gas be communicated with the outer atmosphere of cup when bowl cover is sucked, and bowl cover is opened easily.

The purpose of this utility model is achieved in that

A kind of insulation magnetic cup with ventilation pressure valve comprises cup and bowl cover, it is characterized in that: set a ventilation pressure valve in the centre hole of bowl cover, this ventilation pressure valve is to be made of valve body and spool, has the circular hole guide rail in this valve body, sliding dispensing spool in this circular hole guide rail.

Described spool is made up of button, core bar, spring and sealing-ring, and wherein, button bottom and core bar upper end are affixed, and spring is in button bottom and valve body inside bottom wall, and sealing-ring is clamped between the shoulder of valve body bottom wall outer and core bar.

Owing to adopt such scheme: cup is opened easily, and is easy to use.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments synoptic diagram.

Among the figure:

1, cup 11, interior cover 12, shell 13, magnet piece

2, bowl cover 21, centre hole 3, ventilation pressure valve 31, valve body

311, circular hole guide rail 32, spool 321, button 322, core bar

323, spring 324, sealing-ring

Present embodiment comprises cup 1, bowl cover 2 and ventilation pressure valve 3, as shown in Figure 1, and wherein:

Cup 1 is to be linked into an integrated entity at intervals by interior cover 11 and shell 12, and interior again cover 11 wall outside surfaces are provided with two relative magnet pieces 13, have insulation and hydromagnetic and turn usefulness into, belong to prior art.

Bowl cover 2 is middle lids with thermal insulation layer, screws with its lower end inner edge to be connected on the cup 1 opening end outer rim screw thread, belongs to prior art; The center of bowl cover 2 is provided with a centre hole 21.

Ventilation presses 3 to comprise valve body 31 and spool 32, and valve body 31 is engaged in the centre hole 21 of bowl cover 2, with upper and lower back-up ring valve body 1 is fixed on the bowl cover 2.Also has circular hole guide rail 311 (also having ventilating pit on it) in this ventilation pressure valve 3; Spool 32 is made up of button 321, core bar 322, spring 323 and sealing-ring 324, wherein, button 321 tops are circular arc, the bottom has internal thread hole, the upper end of core bar 322 has outside screw, and the lower end has shoulder, and button 321 lower end internal threads are connected with core bar 322 upper external screw threads, spring 323 is in button 321 bottoms and valve body 31 inside bottom wall, and sealing-ring 324 is clamped between the shoulder of valve body 31 bottom wall outer and core bar 322.

The operation of present embodiment and principle thereof:

When water in the cup turned cold the generation negative pressure, as long as press button 321 gently with finger, spring 323 was compressed, and the shoulder of spool 32 and sealing-ring 324 move down, a gas in the cup and glass outer a connection, and therefore, bowl cover 2 is just opened easily.
