Description
The utility model relates to a kind of pressure cooker safety device.
The release mechanism of existing pressure cooker is of all kinds, but exist a problem, be that structure is comparatively complicated, inconvenience operates, bring inconvenience to the user, as push away and turn round the mechanism pressure pot, in order to satisfy consumer's instructions for use, make the release mechanism use of pressure cooker simple, safe and reliable, need design not have to push away and turn round formula safe pressure cooker handle mechanism.
The purpose of this utility model is to provide a kind of simple in structure, easy to use, pressure cooker safety device that performance is safe and reliable.
The purpose of this utility model is achieved in that
It is that latching valve is installed on pressure cooker cover, and latching valve is provided with spool, and spool can move up and down under the pot inner pressure effect, is provided with chute in the upper handle,
The type self-lock rod is arranged in the chute of upper handle, the top of self-lock rod is provided with centre bore, corresponding with the latching valve spool on the pot cover, the bottom of self-lock rod is provided with locating hole, spring housing is on apical axis, self-lock rod under the effect of spring, but in the upper handle chute back and forth movement, the movement travel of self-lock rod is determined by pot body serratd edge.
The utility model has the advantages that simple in structure, esy to use, safe and reliable.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 does not contact schematic diagram for self-lock rod with pot body serratd edge.
Fig. 3 is the self-lock rod schematic diagram that contacts with a pot body serratd edge.
Fig. 4 closes up schematic diagram fully for pot cover and pot body.
Fig. 5 is the lower handle structural representation.
Fig. 6 is the latching valve structure chart.
Describe the utility model in detail below in conjunction with accompanying drawing:
Shown in Fig. 1-6, it is that latching valve 2 is installed on pressure cooker cover 1, and latching valve 2 is provided with spool 7, and spool 7 can move up and down under the pot inner pressure effect, is provided with chute in the upper handle 3,
Type self-lock rod 4 is arranged in the chute of upper handle 3, the top of self-lock rod 4 is provided with centre bore 9, corresponding with the latching valve spool 7 on the pot cover 1, the bottom of self-lock rod 4 is provided with locating hole, spring housing 5 is on apical axis, self-lock rod 4 under the effect of spring 5, but in the upper handle chute back and forth movement, the movement travel of self-lock rod 4 is determined by pot body serratd edge.
The course of work of the present utility model is as follows:
When pot cover is incorporated into self-lock rod 4 and contacts with a pot body serratd edge 10, self-lock rod 4 moves under the effect of pot body serratd edge 10 backward, as shown in Figure 3, this moment, the centre bore 9 of self-lock rod 4 departed from spool 7, do not come on the spool 7, through hole by latching valve in the pot does not boost with extraneous normal open as shown in Figure 6, and promptly pot cover closes and not in placely do not boost.When pot cover is incorporated into; be that upper handle 3, lower handle 8 overlap fully; self-lock rod 4 makes self-lock rod centre bore 9 concentric with self-locking spool 7 by the effect of spring 5, when in the pot 6 when pressure is arranged; the centre bore 9 that self-locking spool 7 passes self-lock rod 4 floats up; to seal pressurize in the pot, make the pressure cooker operate as normal, simultaneously self-lock rod 4 is pinned; have in the pot this moment and press the lid of not opening, thereby entire mechanism plays the safeguard protection effect.
