Abstract
The utility model discloses an anti-boiling-over pot cover. The pot cover comprises a round cover plate (1) with a hole in the center and a lifting handle (3) located in the center of the round cover plate (1) and fastened though a bolt (2), the bolt (2) and the lifting handle (3) are respectively provided with a vertical through hole and in threaded connection, the lifting handle (3) is provided with a side hole (4) communicated with the through hole of the lifting handle (3), and an adjusting rod (6) with a screwing button (5) at the top end is inserted in the through hole of the lifting handle (3). When water boils in a normal pressure pot, steam in the pot can be exhausted outside the normal pressure pot from the through holes in the bolt (2) and the lifting handle (3) through the side hole (4) to avoid the boiling-over condition, the adjusting rod (6) is moved up and down by means of the screwing button (5) to adjust the ventilation volume of the side hole (4), and therefore the pot cover has the advantages of preventing the boiling-over condition and fully using the optimum state of heat.
Description
Technical field
The utility model relates to a kind of pot cover, more specifically to a kind of boiling-over proof pot cover.
Background technology
Existing normal pressure pot pot cover is by the porose circular cover in center, and the handle by bolted that is positioned at circular cover center forms, in the time stewing burning food, tend to boil over, in pot, liquid flows to the kitchen range top so that stained kitchen range from pot edge, or combustion cell so that flame-out, for the kitchen range taking toxic gas as fuel, as gas range, easily therefore there is the poisoning or explosion accident of human body, as pot cover is opened, although can restrain the situation of boiling over, but can a little fuel of many losses, therefore, provide a kind of boiling-over proof pot cover, tool is of great significance.
Utility model content
The purpose of this utility model is to provide a kind of boiling-over proof pot cover.
The utility model is achieved by following technical proposals:
A kind of boiling-over proof pot cover of the utility model, comprise the circular cover that center is porose, be positioned at the handle by bolted at circular cover center, described bolt and described handle all have upward and downward through hole and mutually borrow and be threaded, described handle is provided with the side opening being connected with its through hole, assigns top band to screw the adjusting rod of button in the through hole of described handle.
Also, described adjusting rod bottom is provided with cavity to a kind of boiling-over proof pot cover of the utility model, and there is a breach cavity wall lower end.
The utility model beneficial effect is compared with prior art:
In the time that normal pressure pot seethes with excitement, in pot, steam-energy is from the through hole of described bolt and described handle, through described side opening discharged to normal pressure pot outside, avoid boiling over situation, described in borrowing, screwing button allows described adjusting rod upward and downward move, to adjust the throughput of described side opening, boil over to reaching neither, make full use of again the optimum state of heat energy.
Brief description of the drawings
It shown in Fig. 1, is the front perspective structure schematic diagram of a kind of boiling-over proof normal pressure of the utility model pot cover.
It shown in Fig. 2, is the cross-sectional side structural representation of a kind of boiling-over proof normal pressure of the utility model pot cover.
It shown in Fig. 3, is the cross-sectional side structural representation of another embodiment of a kind of boiling-over proof normal pressure of the utility model pot cover.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model will be further described.
Shown in Fig. 1 or Fig. 2, a kind of boiling-over proof pot cover of the utility model, comprise the porose circular cover in center 1, be positioned at circular cover 1 center by the fastening handle 3 of bolt 2, described bolt 2 and described handle 3 all have upward and downward through hole and mutually borrow and be threaded, described handle 3 is provided with the side opening 4 being connected with its through hole, assigns top band to screw the adjusting rod 6 of button 5 in the through hole of described handle 3.
Further, for improving the throughput efficiency of adjusting described side opening 4, described adjusting rod 6 bottoms are provided with cavity 7, and there is a breach 8 cavity 7 wall lower ends, screwing in described adjusting rod 6 upward and downward moving process, borrow described breach 8 to change with the amount of area that overlaps of described side opening 4, adjust rapidly the throughput of described side opening 4, as shown in Figure 3.
Described handle 3 and described in screw button 5 and made by plastics or timber, with non-scald on hand, between the root of described bolt 2 and described cover plate 1, be also lined with seal washer.The locate mode of described adjusting rod 6 in the through hole of described handle 3, can borrow screw thread combination or borrow emulsion gasket combination.
Before the boiling of normal pressure pot, twist and or pressure-raising described in screw button 5 and allow described adjusting rod 6 be adjusted to the most the next, to boil over time, described in borrowing, screwing button 5 allows described adjusting rod 6 upward and downwards move, and the amount of area that overlaps of described breach 7 and described side opening 4, to adjust the throughput of described side opening 4, boil over to reaching neither, make full use of again the optimum state of heat energy.
Claims (2)
1. a boiling-over proof pot cover, comprise the porose circular cover in center (1), be positioned at circular cover (1) center by the fastening handle (3) of bolt (2), it is characterized in that, described bolt (2) and described handle (3) all have upward and downward through hole and mutually borrow and be threaded, described handle (3) is provided with the side opening (4) being connected with its through hole, assigns top band to screw the adjusting rod (6) of button (5) in the through hole of described handle (3).
