Description

The overflow-preventing energy-saving pot cover

Technical field

The utility model relates to a kind of life pot cover, particularly a kind of overflow-preventing energy-saving pot cover.

Background technology

Pot cover is the indispensable kitchen utensils of daily life, and effect mainly is to strengthen the pot internal gas pressure and prevent that heat from distributing in a large number.In the prior art, common pot cover is made of lid and handle, and a circular aperture is arranged on the pot cover lid that has, and is used for pressure release.These pot covers particularly when heating gruel and Duo Tang juice food, are easy to occur excessive phenomenon in use, not only cause waste, and influence the kitchen environment health, bring inconvenience to life.Circular aperture on the lid is too little can not to play the pressure release effect, and too conference causes energy waste.And excessive in order to prevent, after food boiled, common way was that pot cover is opened, though spillover can not occur, can cause pot internal gas pressure to reduce significantly with heat and scatter and disappear in a large number, can increase time and many consumes energy of cooking food.

Therefore, need a kind of pot cover, the pot phenomenon that do not occur during use overflowing, and can not cause pot internal gas pressure to reduce significantly with heat and scatter and disappear in a large number can energy savings, reduces food heat time heating time.

The utility model content

In view of this, the purpose of this utility model provides a kind of overflow-preventing energy-saving pot cover, according to circumstances regulates the pressure release amount, the pot phenomenon does not occur during use overflowing, and can not cause pot internal gas pressure to reduce significantly and scatter and disappear in a large number with heat, can energy savings, reduce food heat time heating time.

Overflow-preventing energy-saving pot cover of the present utility model, comprise lid and handle, also comprise pressure relief device, pressure relief device comprises the relief hole that is arranged on the lid, relief tube that is fixedly installed on the lid and leads to relief hole and the pressure release adjustable cap that is provided with staving, be respectively arranged with the annular radial groove on the described relief tube body He on the pressure release adjustable cap staving circumference, two annular through groove axial locations are corresponding, the circumferential lengths of annular through groove is not more than 1/2nd relief tube girths, the staving of pressure release adjustable cap is enclosed within the relief tube excircle, with relief tube radially rotatable shaft to secure fit.

Further, described pressure relief device is a handle;

Further, also comprise female back of the body cap is set, described relief tube lower end is provided with the annular boss of diameter greater than relief hole, annular boss top body is provided with and carries on the back the external screw thread that cap matches, relief tube passes relief hole from inside to outside, by the back of the body cap lid is pressed together between annular boss and the back of the body cap, pressure release adjustable cap staving matches with relief tube by internal thread;

Further, described relief tube upper end mouth of pipe sealing;

Further, the annular radial groove on described relief tube body and the pressure release adjustable cap staving circumference, circumferential lengths equals 1/2nd relief tube girths.

The beneficial effects of the utility model are: when the utility model uses, can adjust the circumferential relative position of the annular radial groove on pressure release adjustable cap and the relief tube, change the pressure release passage size according to operating position, thus the size of control gas output.When need keeping pot internal gas pressure and heat,, staggered in annular radial groove on the pressure release adjustable cap and the annular radial groove position on the relief tube, close venting channels by rotation pressure release adjustable cap; When the needs pressure release, by rotation pressure release adjustable cap, make the annular radial groove on the pressure release adjustable cap relative with the annular radial groove position on the relief tube, venting channels is opened and pressure release, the pot phenomenon of avoiding overflowing.Therefore, do not need to open the pot cover pressure release, the food spillover can not occur, and can not cause air pressure to reduce significantly and scatter and disappear in a large number, thereby energy savings reduces heat time heating time with heat.

Description of drawings

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

Fig. 1 is a section of structure of the present utility model;

Fig. 2 is that the A of Fig. 1 is to view.

The specific embodiment

Fig. 1 is a section of structure of the present utility model; Fig. 2 be the A of Fig. 1 to view, as depicted in figs. 1 and 2, overflow-preventing energy-saving pot cover of the present utility model comprises lid 4 and pressure relief device, in the present embodiment, pressure relief device is the still handle 5 of pot cover simultaneously.Pressure relief device comprises the relief hole 4a that is arranged on the lid, be fixedly installed on the lid 4 and the relief tube 2 of the upper end mouth of pipe sealing of leading to relief hole 4a, female annular back of the body cap 3 be set and be provided with the pressure release adjustable cap 1 of staving 1b, be respectively arranged with annular

radial groove

2a and 1a on described relief tube 2 bodys He on the pressure release adjustable cap staving 1b circumference, annular

radial groove

2a and 1a circumferential lengths equal 1/2nd relief tube girths, and two annular through groove axial locations are corresponding; Relief tube 2 lower ends are provided with the annular boss 2b of diameter greater than relief hole, annular boss 2b top body is provided with the external screw thread that matches with annular back of the body cap 3, relief tube 2 passes relief hole 4a from inside to outside from lid 4 inside, by annular back of the body cap 3 lid is pressed together between annular boss 2b and the back of the body cap 3, avoids pressure to pass through clearance leakage between lid 4 and annular back of the body cap 3 and the annular boss 2b; Pressure release adjustable cap staving 1b is spun on relief tube 2 excircles by internal thread.

Certainly, pressure relief device also can be provided with separately at other positions on lid, and does not serve as handle; Annular radial groove circumferential lengths is not limited to and equals 1/2nd relief tube girths, and can be other numerical value less than this numerical value; Also be not limited to the mode that compresses by back of the body cap thread cooperating between relief tube and the lid, can adopt other connected modes such as screw; Cooperating between pressure release adjustable cap staving and the relief tube also can adopt other can realize radially rotating, and the mode of axial restraint adopts thread connecting mode, and easy accessibility is connected firmly.

The utility model is taked above structure, can be according to operating position, and the annular radial groove on adjustment pressure release adjustable cap and the relief tube changes the pressure release passage size at the relative position of circumferencial direction, thus the size of control gas output.Therefore, do not need to open the pot cover pressure release, the food spillover can not occur, can't cause air pressure to reduce significantly and scatter and disappear in a large number, thereby energy savings reduces heat time heating time with heat.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
