Abstract
The utility model relates to an automatic safety device for opening or closing a cover of a pressure cooker, which is composed of a sealing sleeve, a sealing seat, a supporting seat, an indicating valve, a sealing pad, and sealing screws. The utility model is characterized in that the sealing sleeve without needing any accessory is directly and tightly sheathed with the upper edge of the inner wall of a cooker body; the lower end of the indicating valve is sealed with the sealing pad and the sealing screws; when the pressure cooker is rightly covered, the indicating valve is exactly aligned with the central position of a hole of the sealing sleeve; when the indicating valve is pushed onto the hole of the sealing sleeve by air pressure, a side hole of the lower part of the indicating valve is deadly plugged in a hole of the sealing seat by the sealing pad (8). The utility model has the advantages that manufacturing process is simple; the cost is low; the operation is convenient; the quality of use can be ensured for a long term, the utility model is convenient to produce in large scale, and manufacturers and users can obtain benefits.
Description
The utility model belongs to a kind of pressure cooker open and close cover automatic safety.
In the market, the pressure cooker open and close cover automatic safety has varied, as patent 95244228.0 pressure cooker open and close safety controls, exists complex process, and structure is loaded down with trivial details, and the cost height is difficult to guarantee the long-term weakness of using.
The purpose of this utility model is to provide that a kind of technology is simple, cost is low, easy to operate, can guarantee service property (quality) for a long time, be convenient to the novel pressure cooker open and close cover automatic safety of mass production again, manufacturer and user are really benefited from it.
The utility model is made up of sealing shroud (2), seal receptacle (3), bearing (6), indicator valve (7), sealing gasket (8), sealed screw (9), it is characterized in that sealing shroud (2) does not directly add any annex and is locked in the installing hole of pot cover (1), bearing (6) is fixed tightly in the interior top edges of a pot body (10), and seal receptacle (3) is put into the hole of bearing (6); Indicator valve (7) is put into the hole of seal receptacle (3), indicator valve (7) has centre bore, the bottom communicates with side opening (a), indicator valve (7) lower end seals with sealing gasket (8) and sealed screw (9), get togather when covering at pressure cooker, indicator valve (7) just in time aligns the center in sealing shroud (2) hole, when air pressure during with indicator valve (7) top upper sleeve gasket (2) hole, the sealed pad of side opening (a) (8) of indicator valve (7) bottom blocks in the hole of seal receptacle (3), plays sealing function.
The utility model structure is very reasonable, and technology is simple, and cost is low, is convenient to produce, and quality is good, and durable degree height can prevent reliably that the dangerous phenomenon of incorrect folding lid from taking place, and really belongs to super quality and competitive price at present, stands the successful structure of deliberation, is worth promoting.

Fig. 6 is the schematic diagram of the I-shaped sealing shroud of the utility model through hole (2);
Fig. 7 is the schematic diagram of the utility model through hole T font sealing shroud (2).
As shown in Figure 1, this device is by pot cover (1), sealing shroud (2), seal receptacle (3), spring pad (4), rivet (5), bearing (6), indicator valve (7), sealing gasket (8), sealed screw (9) is formed, earlier in the top edges of pot body (10) towards good installing hole, use rivet (5) that bearing (6) is fixed on the interior top position of a pot body (10) then, desired height is when actual production, can be by adjusting the height of (3) sealing shroud (2) and installing hole, to reach best fit, behind the good bearing of riveting (6), seal receptacle (3) is passed the hole that spring pad (4) is put into bearing (6), again indicator valve (7) is put into the hole of sealing shroud (2), then the sealed screw that has sealing gasket (8) (9) is tightened in the bottom of indicator valve (7), the part installation in the pot.Part on the pot cover (1), dash a round installing hole at the edge of pot cover (1) earlier, then sealing shroud (2) directly is enclosed within on the installing hole, total is just accused installation, positioner can dash a boss at the edge of pot body (10) tooth or pot cover (1) tooth, just can reach the purpose of mutual location.
Its operation principle is: after device installs, when closing lid arrival position location, the bottom of seal receptacle (3) and sealing shroud (2) has elastic force and coincide mutually, to reach the top seal of device, at this moment indicator valve (7) just in time aligns the center in sealing shroud (2) hole, when producing air pressure in the pot, steam is automatically with on indicator valve (7) top, enter in the hole of sealing shroud (2), the aperture (a) of indicator valve (7) bottom is owing to enter in the hole of seal receptacle (3), the sealed screw (9) that has sealing gasket (8) directly is pressed in the bottom of seal receptacle (3) when indicator valve (7) rises, at this moment just played the effect of insurance and sealing.Do not arranged vapour as pressure cooker, indicator valve (7) can not be opened just pin pot cover (1), if after safety has been arranged vapour, owing to do not have pressure in the pot, indicator valve (7) just can fall automatically, can uncap safely.
As shown in Figure 4, when closing lid a bit less and not putting in place as the pressure cooker difference, when indicator valve (7) rises, because it is not corresponding, be subjected to stopping of sealing shroud (2) edge, do not enter in the hole of sealing shroud (2), steam just can be discharged among the through hole of indicator valve (7) or side opening, making does not have pressure in the pot, play to close to cover purpose of safety.
As shown in Figure 5, if it is not in place to close lid, when too wide in the gap, gas just can directly be discharged from the hole of sealing shroud (2) with the position location; As shown in Figure 1, the indicator valve of this device (7) can be a clear opening; As shown in Figure 3, indicator valve (7) can be that the top is obstructed, the side opening type that side has aperture to communicate; As shown in Figure 5, can be the cylinder of blind hole again.Key is that sealing shroud (2) can directly be locked on pot cover (1) in addition, sealing shroud (2) can be the I shape of through hole, or the T font of through hole, two end surfaces are circle, square triangle pentagon hexagon and other geometry, no matter two end surfaces are any geometries about it, install up or down, all play sealing or scavenging action, principle is the same.Have again spring pad (4) must, can be rubber blanket, plastic mattress, metal gasket or metal spring, but want this part help folding and sealing slightly.Also do not work, principle is constant in the same old way.Sealing gasket (8) can be plane, bowl type, annulated column type.In addition, for guaranteeing the flexible up and down of structure, the cylindrical of the inner hole wall of seal receptacle (3) and indicator valve (7) can be processed with pitting or sulculus.
