Specific embodiment
It is to reach technological means and effect that predetermined goal of the invention is taken for the present invention is expanded on further, below in conjunction with attached Figure and preferred embodiment, to the specific embodiment of foundation the present patent application, structure, feature and its effect, describe in detail such as Afterwards.In the following description, the special characteristic in one or more embodiments, structure or feature can be combined by any suitable form.
As shown in Figure 1 and Figure 2, this specific embodiment designs a kind of pressure cooker with lock, including pot cover 1 and pot 2, Described pot cover 1 and described pot 2 are connected;
It is provided with described pot 2 for preventing described pot cover 1 along the freely rotatable lock 3 of the circumference of described pot 2;Described The fit structure 4 being adapted with described lock 3 is provided with pot cover 1;
Or, being provided with described pot cover 1 for preventing described pot cover 1 along the lock 3 circumferentially rotating of described pot 2;Described The fit structure 4 being adapted with described lock 3 is provided with pot 2.
Described pot cover 1 and described pot 2 can be for separately positioned it is also possible to the mode being connected as a single entity be arranged, described pressure Described lock can 3 be arranged in pot 2 by pot, and described fit structure 4 is arranged on pot cover 1, or vice versa also may be used.This two kinds settings Mode can be selected according to the concrete structure setting of pressure cooker.By the described lock 3 that is adapted and described fit structure 4, can To limit the rotation that described pot cover 1 carries out circumferentially with respect to described pot 2, thus preventing child from rotating pot cover 1 due to curious Or move described pressure cooker, cause described pot cover 1 to loosen, come off, thus avoiding causing danger.
Preferably, described pot 2 is provided with and is adapted, with described pot cover 1, the pot opening being connected, described lock 3 is arranged at The edge of described pot opening;It should be noted that pot opening described herein, refer to be opened in described pot 2, be used for The opening of pot inner bag is put into into described pot 2.Described pot opening is adapted with described pot cover 1 and is connected, and can make described pot Body is internally formed the seal cavity for culinary art, thus cooking to the food being positioned in described pot inner bag.Described cooperation Structure 4 is arranged at the edge of described pot cover 1 and is locked at 3 corresponding positions with described.
Preferably, described lock 3 includes extending and protrude from described pot opening rim surface or is contracted to described pot Push rod 31 within body opening edge edge.It is further preferred that described fit structure 4 includes the groove of setting that is recessed, described push rod 31 can be with described groove fit grafting.
That is, when described push rod 31 extends, the function of described lock 3 is opened, and described push rod 31 protrudes from described pot opening Rim surface is simultaneously fixed with described groove grafting, thus limiting the rotation that described pot cover 1 is with respect to described pot 2;When described top When bar 31 shrinks, described push rod 31 can be taken in described pot opening edge along internal completely, thus releasing and described groove Cooperation fixed relationship, that is, close the function of locking 3 so that described pot cover 1 can be rotated with respect to described pot 2, thus entering The normal pressure cooker open and close of row is using operation.This grafting fit system can prevent described pot cover 1 with respect to institute simple and effectively State the rotation of pot 2, thus reducing the potential safety hazard of pressure cooker.
As shown in Figure 3 and Figure 4, as one kind preferably embodiment, described lock 3 includes electromagnetic control structure 32, described Electromagnetic control structure 32 passes through the active force that the change of its connecting and disconnecting of the circuit is applied to described push rod 31, so that described push rod 31 completes The state switching of above-mentioned elongation or contraction.
Preferably, described electromagnetic control structure 32 applies to point to described Electromagnetic Control to described push rod 31 in the energized state The electromagnetic force in structure 32 direction, does not exert a force to described push rod 31 in the power-off state.It is further preferred that on described push rod 31 Be arranged with catch 33 and spring structure 34, described spring structure 34 be located at described catch 33 and described electromagnetic control structure 32 it Between, and one end of described spring structure 34 abutted against with described catch 33, the other end is abutted against with described electromagnetic control structure 32.
Specifically, that is, when described electromagnetic control structure 32 is energized, described electromagnetic control structure 32 is to described push rod 31 Apply captivation so as to be contracted to described pot opening edge along internal, now, lock 3 function closing, one end is connected to described gear Spring structure 34 on piece 33 is in compressive state (see Fig. 4).When described electromagnetic control structure 32 power-off, described Electromagnetic Control Structure 32 stops described push rod 31 is exerted a force, and the described spring structure 34 being in compressive state restores to the original state, by described push rod 31 Jack-up is so as to protrude from the surface on described pot opening edge edge, thus opening the function (see Fig. 3) of lock 3.
Described electromagnetic control structure 32 makes the switching simple and fast of the working condition of described push rod 31, and security performance is relatively Good.
As one kind preferably embodiment, described fit structure 4 includes assembling inclined-plane and the locating slot of connect setting, institute State assembling inclined-plane be used for making described push rod 31 slip into when described pot cover 1 relatively rotates and is connected with described pot 2 described fixed Position groove.The setting on described assembling inclined-plane, is conducive to, in the state of the function of described lock 3 is opened, directly fastening described pot cover 1 It is arranged in described pot 2, the function of described lock 3 need not be closed in advance, need not withdraw described push rod 31 in advance, treat pot cover 1 Open described lock 3 after being rotated in place again, so that described push rod 31 is extended, described pot cover 1 is fixed.This kind of assembling mode can So that described push rod 31 is precisely connected with described fit structure 4, decrease the operating procedure using lock 3 functions, simply simultaneously Convenient, safe.
As one kind preferably embodiment, described push rod 31 is cylindrical structural, and described locating slot is and described push rod 31 slotted eyes being adapted.
As one kind preferably embodiment, described pot 2 is provided with control mainboard 5, described lock 3 controls master with described Plate 5 electrically connects, and described control mainboard 5 is provided with the button for controlling described lock 3.Described mainboard and described lock 3, pressure cooker Heating dish 6 and the part such as display screen 7 one kind preferably annexation as shown in Figure 5.The described pressure cooker with lock 3 Several confined states are as shown in figs 6-8.
To sum up, skilled addressee readily understands that, on the premise of not conflicting, above-mentioned each advantageous manner can from By combination, superposition.
The above, the only better embodiment of the present invention, not the present invention is done with any pro forma restriction.Any People can draw other various forms of products under the enlightenment of the present invention, however, making any change in its shape or structure Change, every have technical scheme identical or similar to the present application, is within the scope of the present invention.
