Moreover, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize the applicability of other processes and/or the use of other materials.

A pot cover 100 for a pressure cooker according to an embodiment of the first aspect of the present invention will now be described with reference to Figs. The lid 100 can be applied to a pressure cooker such as an electric pressure cooker. In the following description of the present application, the description will be made by taking the lid 100 for an electric pressure cooker as an example. Of course, those skilled in the art will appreciate that the lid 100 according to an embodiment of the present invention can also be applied to other types of pressure cookers, and is not limited to electric pressure cookers.

Referring to Fig. 20, the pressure cooker includes a pot body 200 having a pan 201 adapted to engage the lid 100 on the outer peripheral wall of the pot body 200.

Referring to the drawings, a pot cover 100 for a pressure cooker such as an electric pressure cooker according to an embodiment of the first aspect of the present invention includes a cover 1, an exhaust valve 2, a drive member 3, and a control device.

Referring to Fig. 1, an exhaust passage is formed in the cover 1, and an exhaust valve 2 is provided on the cover 1, and the exhaust valve 2 is movable between an open position in which the exhaust passage is opened and a closed position in which the exhaust passage is closed. Specifically, for example, when the pressure cooker is in the cooking operation, the exhaust valve 2 is in the closed position where the exhaust passage is closed, so that a closed space is formed in the pressure cooker, and the pressure in the pressure cooker is continuously increased during the cooking process. Large, thereby speeding up the cooking speed and reducing the cooking time. When the pressure cooker is finished cooking, it is necessary to discharge the steam in the pressure cooker. At this time, the exhaust valve 2 is in the open position of opening the exhaust passage, thereby the inside of the pressure cooker Through the exhaust passage and the outside atmosphere, the steam in the pressure cooker is discharged to the outside of the pressure cooker through the exhaust passage, so that the pressure in the pressure cooker is consistent with the pressure of the outside atmosphere, thereby facilitating the opening of the lid 100.

For example, in the examples of Figures 4 and 7, when the pressure cooker is operating (non-venting), the exhaust valve 2 is moved downward to the closed position to block the exhaust passage, and the pressure cooker is exhausted at the end of cooking. The valve 2 is moved up to the open position to allow the interior of the pressure cooker to communicate with the outside atmosphere. Of course, the present invention is not limited thereto, and the exhaust valve 2 may also be configured to rise during the rotation to realize the opening and closing of the exhaust passage of the exhaust valve 2.

The control device includes at least one of a first control device and a second control device, wherein the first control device includes a first control component 4a and a second control component.

Specifically, the drive member 3 and the first control assembly 4a are both disposed on the cover body 1, and the first control assembly 4a is configured such that the drive member 3 drives the exhaust valve 2 to move from the closed position to the open position and held in the open position. Specifically, referring to FIG. 4, at the end of the cooking of the pressure cooker, the user can drive the driving member 3, at which time the exhaust valve 2 is moved from the closed position to the open position and held in the open position (as shown in the row of FIG. 4). The gas valve 2 moves upward from the position where the exhaust passage is closed to open the exhaust passage), and then the steam in the pressure cooker is discharged from the exhaust passage, and since the exhaust valve 2 is maintained at the position where the exhaust passage is opened, the user It is not necessary to keep pressing the driving member 3, which is convenient for operation and improves the user experience.

It can be understood that the driving member 3 can be a button, and the first control unit 4a is driven to press the first control unit 4a to move the exhaust valve 2 from the closed position to the open position; the driving member 3 can also be a knob, which is rotated by the knob to drive the first A control assembly 4 moves the exhaust valve 3 from the closed position to the open position.

For example, the knob can be rotatably disposed on the cover 1 about the axis of rotation, and when the knob is rotated about the axis of rotation in a first direction of rotation (eg, counterclockwise), the knob moves from the closed position to the open position when the knob is along A second direction of rotation (eg, a clockwise direction) opposite the first direction of rotation is rotated to move the knob from the open position to the closed position. Therefore, the knob can be switched between the open position and the closed position by rotating the knob, which is convenient for the user to use, and can simplify the exhaust structure of the lid 100, is convenient for processing and assembly, saves production cycle, reduces production cost, and also reduces production cost. The lid 100 can be made more beautiful. Here, it should be noted that the “rotation axis” may be the central axis of the knob itself or the central axis of the exhaust passage at the same time.

The second control assembly is disposed on the cover 1 and the second control assembly is configured to cooperate with the pan 201 to open the exhaust valve 2 from the open position by the first control assembly 4a when the cover 1 is opened or closed Position movement. Specifically, when the pressure in the pressure cooker is the same as the external pressure, the user can take out the food cooked in the pressure cooker by opening the cover body 1. When the cover body 1 is opened, the second control component cooperates with the pan tooth 201 to pass the first A control assembly 4a moves the exhaust valve 2 from the open position to the closed position, thereby causing the exhaust valve 2 to be in a state of closing the exhaust passage, thereby solving the problem that the user forgets to adjust the exhaust valve 2 to close the exhaust passage. Preventing the problem that the exhaust valve 2 is not reset (ie, the exhaust valve 2 does not close the exhaust passage) during the next cooking, causing problems such as overflow, poor cooking, and the like.

Of course, after opening the cover 1, if the user mistakenly drives the drive member 3, the exhaust valve 2 is opened. The open position of the passage, the next time the cooking lid is closed, the second control assembly will again cooperate with the pot 201 to move the exhaust valve 2 from the open position to the closed position by the first control assembly 4a, thereby closing the exhaust passage Thus, the reliability of the pressure cooker work is guaranteed.

Wherein the second control device comprises a control assembly 4b, with reference to Fig. 11, the drive member 3 and the control assembly 4b are both disposed on the cover body 1, the drive drive member 3 is vented from the closed position to the open position, and the control assembly 4b is constructed When the control unit 4b is engaged with the drive member 3, the exhaust valve 2 is maintained in the open position. Specifically, at the end of the cooking of the pressure cooker, the user can drive the drive member 3, at which time the exhaust valve 2 is moved from the closed position to the open position, and then the steam in the pressure cooker is discharged from the exhaust passage, and due to the control assembly 4b cooperates with the driving member 3, the exhaust valve 2 is maintained in the open position of opening the exhaust passage, so that the user does not need to keep pressing the driving member 3, and the pressure cooker can be continuously exhausted, thereby facilitating operation and improving the user experience.

It can be understood that the driving member 3 can be a button, and the button is driven to drive the exhaust valve 2 to move from the closed position to the open position; the driving member 3 can also be a knob that is rotated by the knob to drive the exhaust valve 3 from the closed position. The position moves to the open position.

The control assembly 4b is disengaged from the drive member 3 when the cover 1 is opened or closed to fit or rotate the drive member 3 to move the exhaust valve 2 from the open position to the closed position. When the pressure in the pressure cooker is consistent with the external pressure, the user can take out the cooked food by opening the cover 1, and while the cover 1 is opened, the control assembly 4b is adapted to cooperate with the pan 201 to disengage from the drive member 3 The gas valve 2 moves from the open position to the closed position, so that the exhaust valve 2 closes the exhaust passage, solving the problem that the user forgets to adjust the exhaust valve 2 to close the exhaust passage, preventing the exhaust valve 2 from being closed during the next cooking. The reset (exhaust valve 2 does not close the exhaust passage) causes problems such as overflow, poor cooking, and the like.

Of course, after the cover body 1 is opened, if the user mistakenly drives the driving member 3 so that the exhaust valve 2 is in the open position to open the exhaust passage, the driver member 201 will be controlled again when the cover 1 is closed for the next cooking. The assembly 4b cooperates to move the exhaust valve 2 from the open position to the closed position, thereby closing the exhaust passage, thereby ensuring the reliability of the operation of the pressure cooker.

At the same time, the user erroneously operates the driving member 3 during cooking, and the driving member 3 can be rotated (for example, rotated in the i direction in FIG. 14) to disengage the control assembly 4b from the driving member 3 to open the exhaust valve 2 from the opening. The position moves to the closed position, thereby continuing to cook and improving the ease of operation.

Further, during the continuous evacuation of the pressure cooker, the drive member 3 can be driven by rotation (for example, rotation in the i direction in FIG. 14) to disengage the control assembly 4b from the drive member 3 to move the exhaust valve 2 from the open position to the closed position. The movement, so as to achieve the manual end of the exhaust early, and thus achieve the purpose of controlling the exhaust time.

A pot cover 100 for a pressure cooker such as an electric pressure cooker according to an embodiment of the present invention, by providing a first control unit 4a, When the pot cover 100 is applied to a pressure cooker such as an electric pressure cooker, continuous exhausting of the pressure cooker can be realized, which is convenient for the user to operate and improve the user experience. By providing the second control component, the exhaust valve 2 can be realized while opening and closing the cover body 1 The reset prevents the exhaust valve 2 from being reset during the next cooking, causing overflow, poor cooking, etc., or by setting the driving member 3 and the control assembly 4b, the continuous exhaust of the pressure cooker can be realized, which is convenient for the user to operate and improve the user experience. And the opening of the exhaust valve 2 can be realized when the cover body 1 or the rotary driving member 3 is opened or closed, preventing the exhaust valve 2 from being reset when the cooking valve 2 is not reset, causing overflow, poor cooking, and the like, and controlling the exhaust gas. time.

For example, as shown in FIGS. 1 and 6, the slider 42a can be movably coupled to the cover body 1 by a fixing screw 425a, and the slider 42a is configured to be driven to drive. The member 3 is then engaged with the first lever 41a to maintain the exhaust valve 2 in the open position, disengaged from the first lever 41a when the cover 1 is opened or closed to move the exhaust valve 2 from the open position to the closed position. When the user drives the driving member 3 to move the second end 412a of the first lever 41a upward to lift the exhaust valve 2, the slider 42a cooperates with the first lever 41a to maintain the exhaust valve 2 in the open position, thereby achieving continuous row The purpose of the gas, and the user does not need to press the driving member 3 all the time. After the pressure is released, when the cover 1 is opened or closed, the slider 42a is disengaged from the first lever 41a to move the exhaust valve 2 from the open position to the closed position, thereby realizing the reset of the exhaust valve 2.

Further, the slider 42a may be located at the second end 412a of the first lever 41a. For example, referring to FIGS. 2 to 4, when the user drives the driving member 3 to move the second end 412a of the first lever 41a upward to lift the exhaust valve 2, the one end 421a of the slider 42a can protrude into the first lever 41a.

Of course, the present invention is not limited thereto. In other optional embodiments of the present invention, the slider 42a may also be located above the first end 411a of the first lever 41a, and after driving the driving member 3, the one end 42a1 of the slider 42a may be The top end of the first end 411a of the first lever 41a is extended to maintain the exhaust valve 2 in an open position (not shown).

Further, referring to FIGS. 3 and 9, the one end 421a of the slider 42a has an abutment surface 422a adapted to abut against a side surface of the second end 412a of the first lever 41a. The user can drive the driving member 3, the side surface of the second end 412a of the first lever 41a and the abutting surface 422a of the one end 421a of the slider 42a are stopped and moved upward relative to the slider 42a until the second end of the first lever 41a The side surface of the 412a is disengaged from the abutting surface 422a of the one end 421a of the slider 42a. Then, the one end 421a of the slider 42a projects under the action of the fourth spring 424a into the bottom of the second end 412a of the first lever 41a to make the row The gas valve 2 is held in the open position.

Alternatively, referring to FIG. 9, the abutting surface 422a is formed as a slope that obliquely extends from the bottom to the top toward the center of the first lever 41a, thereby facilitating the side surface of the second end 412a of the first lever 41a. Good cooperation.

Further, the second control assembly includes a control member 5a that cooperates with the slider 42a to move the slider 42a in a direction away from the first lever 41a when the cover 1 is opened or closed. For example, when the cover 1 is opened, the control member 5 cooperates with the slider 42a to move the slider 42a in a direction away from the first lever 41a, and the one end 421a of the slider 42a is from the second end 412a of the first lever 41a. The bottom is disengaged, and the second end 412a of the first lever 41a moves downward so that the exhaust valve closes the exhaust passage, thereby solving the problem that the user forgets to adjust the exhaust valve 2 to close the exhaust passage.

Of course, after the cover 1 is opened, if the user mistakenly drives the drive member 3 to cause the exhaust valve 2 to be in the open position, the control member 5a and the slider 42a are re-engaged at the same time that the cover member 1 needs to be closed for the next time to make The slider 42 is moved away from the first lever 41a such that the one end 421a of the slider 42a is disengaged from the bottom of the second end 412a of the first lever 41a to close the exhaust passage.
