[specific embodiment]

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

Referring to Fig. 1 to Fig. 6, the utility model provides a kind of one-point type stepless air bleeding valve, includes bonnet 1, gravity drop hammer 2 and valve seat 3.Wherein, described bonnet 1 encases the upper end of gravity drop hammer 2, and its top is provided with steam vent 11, and the lower end rim of described bonnet 1 is the bung flange inclined-plane 12 that rises gradually, these 12 head and the tail two ends, bung flange inclined-plane are connected to form a spacing block face 13, are mainly used in that this air bleeding valve is in sealing state and position; Described gravity drop hammer 2 is made by metal material, perhaps adopt plastic sheath genus covered with gold leaf or plastic sheath bag magnet piece structure fabrication to form, be provided with the cavity 21 that communicates up and down in it, cavity 21 communicates with steam vent 11, and be provided with a sealing 22 in it, described sealing 22 is an awl body, and is one-body molded with gravity drop hammer 2, or by the assembly connection one; Described valve seat 3 is provided with the installation cavity 31 of an opening upwards, be provided with a blast pipe 32 in the described installation cavity 31, be provided with exhaust passage 33 in the blast pipe 32, the tapering, lower end 221 of institute's awl body 22 is complementary with the exhaust outlet of exhaust passage 33, and the inside side walls of installation cavity 31 is provided with exhaust limited support section 34 and sealing limited support section 35, described exhaust limited support section 34 and sealing limited support section 35 are the brace rod of longitudinal design, and one-body molded with valve seat 3.During assembling, described bonnet 1 and gravity drop hammer 2 are rotatably installed in the installation cavity 31, described exhaust limited support section 34 and sealing

limited support section

35 and 12 the face sliding-contacts in bung flange inclined-plane, and support bonnet 1 and gravity drop hammer 2, described blast pipe 32 is inserted in the cavity 21, and sealing 22 is separated or is tightly connected with blast pipe 32 with gravity drop hammer 2 rotations, and described bonnet 1, gravity drop hammer 2, sealing 22 and exhaust passage 33 are positioned on the same axle center.

The operation principle of air bleeding valve described in the utility model is: when described bonnet 1 and gravity drop hammer 2 are packed the installation cavity 31 of valve seat 3 into when interior, the bung flange inclined-plane 12 of bonnet 1 is pressed in the exhaust limited support section 34 in the valve seat 3 and seals in the limited support section 35, at gravity drop hammer 2(gravity or magnetic force) effect under, relative sliding motion is made with exhaust limited support section 34 and sealing limited support section 35 in described bung flange inclined-plane 12, automatically fall to installation cavity 31 bottoms, sealing 22 also drops to blast pipe 32 places, its tapering 221 seals up the exhaust outlet of exhaust passage 33, air bleeding valve is processed sealing state, and described spacing block face 13 just contacted with sealing limited support section 35 and was connected this moment; If pressure does not reach specified atmospheric pressure value in the pot, sealing 22 seals blast pipe 32 by gravity drop hammer gravity or magnetic force, if surpass specified atmospheric pressure value, sealing 22 is separated with blast pipe 32 by pot internal gas pressure jack-up, automatically realizes exhaust, regulates the pot internal gas pressure; Certainly, if when needing as early as possible exhaust, also manually counter clockwise direction (discharge directions) is rotated described bonnet 1 and gravity drop hammer 2, in exhaust

limited support section

34 and 12 actings in conjunction of bung flange inclined-plane, bonnet 1 and gravity drop hammer 2 are elevated gradually, the tapering 221 of sealing 22 is separated gradually with the exhaust outlet of exhaust passage 33, realize exhaust.

Like this, but air bleeding valve described in the utility model is automatic vent both, regulate pot internal gas pressure intensity, greatly improved the pressure cooker security, but exhaust is finished in manual operation again, regulate, and bung flange inclined-plane 12 is sliding motions that point contacts with face with respect to exhaust limited support section 34, the angular dimension of the described bonnet 1 of hand rotation and gravity drop hammer 2 is adjustable gradually in addition, namely the height between sealing 22 and the blast pipe 32 is adjustable, thereby realize the adjusting of capacity size, simple to operate, convenient, move smooth and easy, without catching phenomenon, use also flexible, reliably, practical, simultaneously its

spacing block face

13 and 35 actings in conjunction of sealing limited support section have been avoided misrouting direction and have been caused capacity excessive and make the food ejection, even user's injury, the user also can be different food bonnet 1 and gravity drop hammer 2 are turned to that gas is discharged and without the position of food jet flow, convenient, save time; And this exhaust structure is simple, and thickness is easy to control, thickness is even, outward appearance shrink phenomenon can not occur.

As the utility model one preferred embodiment, described bonnet 1 is provided with regulating handle 14, described regulating handle 14 is positioned at steam vent 11 outsides, and stretch out outside the valve seat 3, also be provided with an icon instruction unit 36 that is used to indicate " sealing " state, " exhaust " state and corresponding turn marking on the described valve seat 3, and described bonnet 1 and regulating handle 14, described valve seat 3 and icon instruction unit 36 are respectively by the plastic material integrated injection molding.When within described bonnet 1 and gravity drop hammer 2 are packed the installation cavity 31 of valve seat 3 into, being positioned at the bottom, regulating handle 14 is being aimed on icon instruction unit 36 " sealing " state position, the user can be by the direction indication of corresponding turn marking on the icon instruction unit 36, and by stirring regulating handle 14 described bonnet 1 and gravity drop hammer 2 rotated, regulate capacity, very clear, operate more clear, simple, convenient, save time, safety, worried without scalding.

Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
