Fig. 3 is that the utility model pulling block connector carries out hinged a kind of embodiment schematic diagram with the pot body.As Fig. 3, connector becomes flexible with crown cap directly or indirectly and is connected, and its connected mode and Fig. 1 are roughly the same.Connector be connected through the hinge again structure (17) with the pot body (9) be connected.
Fig. 4 is that the utility model has the pot cover of plastic hoop to connect a kind of schematic diagram of pot cover Contiuum type of pot body with the metal latticing.
As Fig. 4, plastic hoop (12) is made of one and is fixed on the crown cap with pushing block (1), and metal latticing (16) one ends utilize hinge engaging structure (17) to be connected with the pot body, and other connected mode is similar to Fig. 2.
Fig. 5 is the utility model connects the pot body with plastic hoop a kind of schematic diagram of Contiuum type structure.
As Fig. 5, plastic hoop and pushing block are made of one, plastic hoop be connected through the hinge structure (17) (coating black is represented) with the pot body (9) be connected; Connector (4) can be fastenedly connected on crown cap in various manners, and the two can not become flexible on in-plane; The interior circle of the cylindrical of connector and plastic hoop utilizes the whole bag of tricks to be connected, and makes crown cap can be attached in various operations on the plastic hoop and rotate around its center that crown cap can not loose.As shown in Figure 5, plastic hoop can have low level snap ring (19) in interior round bottom, and the connector cylindrical is stuck on the low level snap ring, and crown cap both can combine with plastic hoop like this, and the two can do relative rotation again.Pot cover is in the plane with hanging a pot body (9) upside behind the finger push-and-pull Unscrew.Here to illustrate, pushing block that this is routine and plastic hoop cannot rotate, be that connector and the pulling block that is fastenedly connected with crown cap can rotate on the contrary, when cooperating with other finger with hand thumb, not before pushing block is pushed to clockwise, but after pulling block was pulled to counterclockwise, because the two has done to relatively rotate, its effect was identical with above-mentioned each example.
Fig. 6 is a kind of schematic diagram of pot cover separate type that the utility model has plastic hoop.
In each example of above-mentioned Fig. 1 to Fig. 4 in the time will opening pot cover, with the hand thumb jacking on pushing block (1), all the other fingers are by use the push-and-pull of making a concerted effort on pulling block, clockwise direction promptly rotates to a pot tooth to pot cover and deviates from the position, smoothly pot cover is taken out a pot body (if pot cover separate type) or smoothly pot cover is hung pot (if pot cover Contiuum type) on one's body simultaneously.The crown cap of Fig. 5 and Fig. 6 is opposite with the direction of rotation of pulling block connector.Above-mentioned rotation and turn over and hang or take out two operation sequences of pot cover and only need the operation sequence that action of single hand links up to finish does not need the another hand to cooperate, and whole operation is convenient and strength-saving, and action links up, and accomplishs without any letup.
On the basis that above-mentioned one hand is uncapped, close the also available singlehanded finger of lid and cooperate.Make the step-by-step (14) that conveniently firmly to push near the pushing block position at above-mentioned each figure pulling block with finger, with hand thumb by being pressed in the step-by-step, all the other fingers are by on the back of pushing block (1) (uncapping is the front of jacking at pushing block), and finger is with can conveniently closing lid (also available left-handed operation) with joint efforts.
If pulling block is not a crab hull shape but bar shaped then need not step-by-step (14).So-called crab hull shape, it is unlimited on one side to be meant that generally pushing block has only, and another side is the arc or the en shape of sealing, and the arc of sealing or en shape are connected on the connector, and there are enough spaces the centre, and finger can insert takes pot cover, but can not pass; So-called bar shaped is meant and overlooks that pulling block is bar shaped (bar shaped can be a different shape) when seeing pot cover, and pulling block is shapes such as bending or rectangle when seeing when pot cover is kept flat, and two limits can be opened wide or not open wide, as long as finger can conveniently lift.
The float-controlled valve structure of the split type pressure cooker of commercially available pot cover relies on the spring interlock to work, and this complex structure is higher to each parts technological requirement, the cost height, and make a fault easily and cause safety problem.The utility model has overcome above-mentioned defective, and its float-controlled valve structure does not need remaining part, has only a float-controlled valve itself to cooperate and can work fully reliably with the hole of connector or plastic hoop.Its mechanism is as follows: float-controlled valve is connected the crown cap below, connector or plastic hoop porose (10), and there is float-controlled valve (11) at the crown cap place when the pressure cooker fastening puts in place under hole (10).If connector integral body is not circular, such form also can be made in the position of float-controlled valve: when the pot cover fastening put in place, float-controlled valve was near the edge of connector, and as air pressure is arranged in the pot, float-controlled valve can rise and float up; When pot cover fastens when not in place, the float-controlled valve connected body covers, and can not come on the buoyance lift.When in the pot air pressure being arranged, pot cover can not be opened.Here explanation: with the connector of float-controlled valve coupling except that being the connector itself, also can be other parts that are connected with connector.
With attractive in appearance, the nearly crown cap of pushing block center one end and pulling block connector closely this end part can be made isocentric circular arc for convenience.
Fig. 7 is the schematic diagram that cross-like is made at the approaching place of pushing block and pulling block (or connector).Because the thermal coefficient of expansion of plastics is bigger, if lean on too closely at ordinary times, will be difficult to the pot cover of outwarding winding to pushing block and pulling block connector when high temperature; If the two distance is too big, can expose a big seam, influence attractive in appearance.Adopt as shown in Figure 5 method to make cross shaped head, can address the above problem.
Fig. 8 is wherein a kind of embodiment schematic diagram that pulling block is done the embayment bar shaped.
If the left hand personage uses, the position of pushing block of the present utility model and pulling block and direction can be exchanged, and the right hand makes left hand into during use, make into clockwise counterclockwise.
Clean for pot cover Contiuum type structure is convenient, the latch in the hinge engaging structure of the present utility model can be made the pattern of taking out reeve easily, and then pot cover is taken out thereupon when taking out latch, the convenient cleaning.Cleaning finishes can be convenient for assembly.
