Detailed Description
The invention is described in further detail below with reference to the drawings and the detailed description.
Referring to fig. 1-18, a rotary pressure cooker comprises a cooker body 1 and a cooker cover 2 covered on the cooker body 1, wherein an upper handle 3 and a float valve 4 are arranged on the cooker cover 2, a lower handle 5 is arranged on the cooker body 1, and a locking mechanism is arranged between the upper handle 3 and the lower handle 5.
The upper handle 3 and the lower handle 5 are overlapped up and down after closing the cover, and the upper handle 3 and the lower handle 5 are locked by the locking mechanism. After the air pressure in the pressure cooker is reduced, the float valve 4 falls down to open the cover, and the upper handle 3 and the lower handle 5 are staggered after the cover is opened.
The upper handle 3 is internally provided with a lock piece 6 which can move back and forth along the length direction of the upper handle 3.
The upper handle 3 is also internally provided with an elastic piece 7, the elastic piece 7 props against the lock piece 6, and the lock piece 6 is far away from the float valve 4 under the action of the elastic piece 7 in a closing state, so that the float valve 4 can normally float. The elastic element 7 is preferably a spring, but other elastic elements, such as a spring plate, may of course be used instead.
The upper handle 3 is also provided with a driving piece, the locking piece 6 is driven by the driving piece to overcome the elasticity of the elastic piece 7 when the cover is opened, and the locking piece 6 moves towards the float valve 4 and blocks the float valve 4, so that the float valve cannot rise and be sealed.
The upper handle 3 is also internally provided with a positioning block 17, the positioning block 17 is movable, the positioning block 17 is in an avoiding position in a cover closing state, and the positioning block does not position the locking piece 6 at the moment.
After the lock 6 moves forward during the opening, the positioning block 17 automatically moves to the positioning position, and the lock 6 is positioned by the positioning block 17 at the positioning position.
When the cover is closed again, the locking mechanism acts on the positioning block 17 to enable the positioning block 17 to reach the avoiding position, so that the locking piece is automatically reset.
In this embodiment, the specific structural form of the lock member 6 and the specific structural form of the locking mechanism are: the lock 6 comprises a lock plate 8 and a lock tail end 9 arranged at the tail of the lock plate 8, and the lock tail end 9 is provided with an inner cavity 10. The locking mechanism comprises a locking column 11 arranged on the lower handle 5 and an inner cavity 10 at the tail end of a locking piece, wherein the locking column 11 enters the inner cavity 10 at the tail end of the locking piece when the cover is closed, so that the aim of locking the upper handle 3 and the lower handle 5 is fulfilled, the locking column 11 cannot be opened, and the locking column 11 is separated from the inner cavity 10 at the tail end of the locking piece when the cover is opened.
In this embodiment, the specific way of the lock cylinder 11 entering and exiting the inner cavity 10 is as follows: the tail end of the lock is provided with a notch 12 communicated with the inner cavity 10, the notch 12 is arranged on the side surface of the tail end 9 of the lock, which is far away from the positioning block, the lock column 11 enters the inner cavity from the notch 12 when the lock is closed, and the lock 6 moves backwards under the action of the elastic piece 7, and then the lock column 11 further penetrates into the inner cavity 10 of the tail end of the lock; when the cover is opened, the lock 6 moves forwards, the notch 12 is aligned with the lock column 11, and the lock column 11 exits the inner cavity 10 at the tail end of the lock through the notch 12.
In this embodiment, the driving member is a shift fork 13 rotatably connected to the upper handle, and the lock member 6 is shifted by the shift fork 13. The lock 6 is provided with a shifting shaft 14, and the shifting fork 13 shifts the shifting shaft 14 so as to drive the lock.
For convenient installation, the concrete installation mode of shift fork is: a plug 15 is arranged, and the shifting fork 13 penetrates through the plug 15 and then penetrates into the rotating shaft 16, so that the shifting fork 13 is rotatably arranged on the plug 15; the upper handle 3 is provided with a socket, after the shifting fork 13 is installed on the inserting block 15, the inserting block 15 is inserted into the socket to be connected and positioned in a clamping way, so that the installation is simple and convenient, and the appearance of the upper handle is not damaged.
Of course, the structure of the driving member is not limited to a fork, and the driving member can drive the locking member to move. For example, a sliding button arranged on the upper handle is used for connecting with the locking piece, and the locking piece is driven to move by sliding the sliding button. Of course, the sliding button and the locking piece can be fixedly connected or movably connected, for example, the sliding button is hinged with the locking piece after being provided with a connecting rod, or is connected with the locking piece by adopting a spherical hinge, or is connected with the shifting fork by adopting a shifting way, and the like.
In this embodiment, the positioning block 17 is rotatably disposed in the upper handle 3, and a torsion spring 18 is further disposed in the upper handle, where the torsion spring 18 acts on the positioning block 17 to make it have a tendency to rotate inwards. The lock tail end 9 is provided with a positioning surface 19, and the positioning block 17 is in an avoidance position in a closed cover state, and the positioning block 17 is separated from the positioning surface 19. After the locking piece 6 moves when the cover is opened, the positioning block 17 automatically moves to a positioning position under the action of the torsion spring 18, and at the moment, the positioning block 17 is propped against the positioning surface 19 so as to position the locking piece 6. When the cover is closed again, the lock column 11 pushes the positioning block 17 open, so that the positioning block 17 reaches the avoiding position, and the lock piece 6 is automatically reset. The positioning surface 19 in this embodiment is formed as follows: the side of the tail end 9 of the locking piece is provided with an inner groove 21, the end face of the inner groove 21 forms the positioning surface 19, and after the driving piece drives the locking piece 6 to move forwards, the positioning block 17 automatically falls into the inner groove 21 under the action of the torsion spring, so that the positioning block 17 is propped against the positioning surface 19.
As a preferential scheme, the positioning surface 19 is arranged on the side surface, close to the positioning block, of the tail end 9 of the locking piece, when the positioning block 17 is at the avoiding position, the positioning block 17 is positioned on the outer side of the positioning surface 19, and the side surface of the locking piece with the positioning surface limits the positioning block 17 to be at the avoiding position all the time.
As a preferred solution, the positioning block 17 has a protrusion 20, the protrusion 20 extends into the inner cavity 10 of the tail end of the locking member, and the locking post 11 acts on the protrusion 20 when closing the cover, so as to push the positioning block 17 to the avoiding position.
Of course, the positioning block 17 is not only rotatably mounted on the upper handle, but also may be movable, for example, the positioning block may be movable, and the movement direction of the positioning block is perpendicular to the upper handle (i.e., the movement direction of the positioning block is along the width direction of the upper handle), and is supported by a spring to have a tendency to move inward. The positioning block is also positioned at the avoiding position in the closing state, so that the positioning of the locking piece is not formed; the locking piece moves forwards when the cover is opened, the positioning block automatically moves to the positioning position under the action of the spring, and the positioning surface of the locking piece abuts against the positioning block to position the locking piece.
In summary, the invention can open the cover by rotating the upper and lower handles only by operating the driving member when opening the cover; when the cover is closed, the cover can be closed after the upper handle and the lower handle are rotated, and the locking between the upper handle and the lower handle is automatically achieved.
