Abstract

A steam valve of an electric cooker is disposed on a top cover of the electric cooker and comprises a valve seat, a bonnet, an exhaust passage, a handle, a limit part, a first spring and an expansion device. The bonnet is fitted to the valve seat. The exhaust passage forms in the valve seat and the bonnet. The handle capable of moving from a first position to a second position axially along the bonnet is disposed on the bonnet. When the handle is at the first position, the upper end of the handle extends out of the surface of the bonnet. When the handle is at the second position, the upper surface of the handle and the upper surface of the bonnet are coplanar, or the upper surface of the handle and the upper surface of the bonnet are connected to form a smooth camber surface. The limit part is arranged on the bonnet and capable of keeping the handle at the first position. The first spring is sleeved outside the handle, and one end of the first spring is abutted to the bonnet. The expansion device has an expansion position and a retraction position and is provided with a brake end allowing the expansion device to change from the expansion position to the retraction position. When the expansion device is at the expansion position, the handle is kept at the first position. When the expansion device is at the retraction position, the handle is kept at the second position.

Description

A kind of electric cooker steam valve

Technical field

The invention belongs to the small household appliances field, be specifically related to a kind of electric cooker steam valve.

Background technology

Electric cooker on sale in the market, steam valve is installed on the cover mostly, and steam valve periphery or will design pulls down the required attacker position of steam valve on one side; The steam valve of this structure is pulled down the required attacker position of steam valve because having designed at cover, thus very large to the appearance effects of whole cover, cannot cover do very exquisite and high-grade.

Summary of the invention

The object of the present invention is to provide a kind of periphery and electric cooker cover applying degree fine and be equipped with the electric cooker steam valve of concealed handle.

For reaching goal of the invention the technical solution used in the present invention be:

A kind of electric cooker steam valve, it is installed on the electric cooker cover, comprises

Valve seat;

Valve gap cooperates installation with above-mentioned valve seat; The exhaust passage is formed in above-mentioned valve seat and the valve gap;

It is characterized in that: described valve gap is provided with can be along the axial mobile handle between primary importance and the second place of valve gap;

Handle is in primary importance, and the valve gap face is stretched out in its upper end; Handle is when being in the second place, and coplanar or its upper surface of its upper surface and valve gap upper surface and valve gap upper surface connect into the cambered surface of rounding off;

Limiting section is located on the valve gap, can make handle remain on primary importance;

The first spring, an end is against handle one end against valve gap;

Expansion bend, it possesses one and upholds the position with punctured bit and make this expansion bend uphold the dog point of position with the punctured bit variation;

Expansion bend is in when upholding the position, and handle remains on primary importance; When stretcher was in punctured bit, handle remained on the second place.

Further, described handle is provided with triggering section, and when described handle moved between primary importance and the second place, described triggering section pressed dog point and makes described expansion bend at punctured bit and uphold between the position and change.

Further, described expansion bend comprises

Shell, it is installed in the valve gap;

Pulling buckle, it can uphold installation mobile between position and the punctured bit in the enclosure, possesses dog point and can uphold the attacker of contraction; When the attacker upheld, pulling buckle is in upheld the position; When the attacker shrank, pulling buckle was in punctured bit;

The second spring, the one end is against pulling buckle, and the other end is against shell;

Slip hook, it is installed in the enclosure, can make pulling buckle be in punctured bit;

Retainer, it is located on the shell, pulling buckle is in upholds the position.

Further, also be provided with the waist button that cooperates locking with slip hook on the described pulling buckle, the upper surface of described waist button is one to cooperate the buckle portion of the V-shape of locate pulling buckle with slip hook upper end, and the side of described waist button is that a slip hook can be along the arc surface of downslide, is that a slip hook can be along the lower inclined plane of upper cunning bottom it.

Further, described pulling buckle above the buckle portion of waist button, be provided with a slip hook can be along sliding ramp.

Further, described pulling buckle is provided with the hook portion that cooperates with retainer.

Further, described valve seat is provided with return valve.

When the present invention uses and cover be assembled together, when pulling down: press handle with hand, the dog point of the triggering section compression expansion bend on the handle, expansion bend is moved down, the slip hook in the shell left the buckle portion that waist buckles and contacted with the ramp of pulling buckle this moment, slided to the right by the active force of ramp, unclamp the power of pressing handle this moment, slip hook slides along the arc surface of waist button, the buckle portion that this moment, waist was buckled has broken away from the restriction of slip hook, pulling buckle moves up under the acting force of the spring of the second spring, until the hook portion on the pulling buckle is moved on stopping when retainer on the shell contacts, expansion bend is in upholds the position, and this moment, the attacker stretched out to both sides, opened with the triggering part on the handle, handle moves up under the active force of the first spring, until limiting section place handle stops to move up, handle is in primary importance, and can pull down of the present invention electric cooker steam valve with pulling handle this moment.

When hiding handle, press handle with hand, handle moves down, the triggering section of handle pushes down the dog point of expansion bend, expansion bend is moved down, and the buckle portion of the slip hook of this moment in the shell along the lower inclined plane upward sliding of waist button to the waist button makes the pulling buckle spiral-lock in the enclosure, expansion bend is in punctured bit, the attacker shrinks to the center simultaneously, encases the triggering section on the handle, and handle is in the second place, unclamp the power of pressing handle this moment, this moment, electric cooker steam valve of the present invention was returned to original state.

The effect that the present invention is useful is: in use micropressure valve around fine with the applying degree of cover, need not to arrange at cover the position of special handle, and during original state, handle can be hidden in the steam valve cap, can make cover accomplish exquisiteness and top grade.
