The invention provides a lid assembly for a pressure cooker.

As shown in FIGS. 1 to 3, the lid assembly of the embodiment of the present invention includes a lid 10, a guide member 20, a slider 30, a self-locking pin 40, and a float 50. The lid 10 is provided with a lid guide hole 11 as shown in FIG. 5 and FIG. 6; the guide member 20 is disposed on the lid 10, and the guide member 20 includes a first guiding portion 21, a second guiding portion 22 and a connecting portion. a first connecting portion 23 of the guiding portion 21 and the second guiding portion 22, and the second guiding portion 22 is provided with a guiding hole 24 corresponding to the cover hole 11 of the lid, the first guiding portion 21, the second guiding portion 22 and the A connecting portion 23 forms a guiding cavity; the slider 30 is disposed in the guiding cavity and is slid therein, the guiding cavity is used for defining the degree of freedom of the slider 30 to move up and down and the degree of freedom of horizontal swing; the self-locking pin 40 is disposed on the sliding On the block 30, the two ends of the self-locking pin 40 respectively pass through the cover hole 11 and the guide hole 24; the float 50 is disposed on the cover 10, and the slider 30 is provided with a limiting portion corresponding to the float 50, the limiting portion It is configured to cooperate with the float 50 when the float 50 floats to define the degree of freedom of horizontal movement of the slider 30.

In general, as shown in Figures 4 through 6, the pressure cooker further includes a pot body 60 for opening and closing the pot body 60 in the embodiment of the present invention. When the lid assembly of the present invention is closed to the pot body 60 for cooking, when the steam pressure in the pot body 60 is too large, the float 50 on the lid 10 is lifted up, and at this time, the float 50 is limited to slide. Block 30 limits the position of the bit portion, thereby defining the degree of freedom of horizontal movement of slider 30. In addition, the guiding cavity defines the degree of freedom of the slider 30 to move up and down and the degree of freedom of horizontal swing, and the self-locking pin 40 is disposed on the slider 30. At this time, the self-locking pin 40 is also limited to the slider 30. At a certain position, the self-locking pin 40 generally cooperates with the structure on the pot body 60 to lock the position of the lid assembly. At this time, the self-locking pin 40 is just in the locked position, so that when the pressure in the pressure cooker is reached, it cannot be used. A small force opens the purpose of the pressure cooker.

Of course, a handle (not shown) is also provided on the lid 10 to facilitate the user to open the lid 10, which is generally connectable with the guide member 20, thereby increasing the firmness of the handle.

When the pressure in the pressure cooker is reduced and the float 50 returns to the initial position, the definition of the slider 30 is released. At this time, the restriction of the self-locking pin 40 is also released, and the lid assembly can be safely opened without the inside of the pot. In the case of a large pressure, there is a problem that the lid 10 can be forcibly opened with a small force, causing a problem that the food in the pot is ejected and injuring people.

Since the slider 30 is slidable within the guiding cavity of the guiding member 20, however, in the prior art, the plurality of components included in the guiding member 20 are generally discretely disposed, and manufacturing tolerances and assembly errors of the plurality of components themselves are This will cause a large disturbance to the accuracy of the moving position of the slider 30, and it is easy to cause the slider 30 to be unrestricted when the float 50 is floated, or the slider 30 is not sufficiently fixed, thereby making it possible to use The problem of forcibly opening the lid 10 by a small force is likely to cause an accident in which the food in the pot is sprayed and wounded.

To this end, as shown in FIG. 5 and FIG. 6, in the embodiment of the present invention, the first guiding portion 21, the second guiding portion 22 and the first connecting portion 23 are integrally formed, and thus, the guiding member 20 is a component which is manufactured. When the guide member 20 is used, the manufacturing tolerance of the guide member 20 itself can be greatly reduced, and when the guide member 20 is mounted, the error caused by the assembly between the plurality of components can be effectively avoided, thereby aligning the slider 30 in the guide member 20. The movement makes an effective guiding and limiting action to avoid the problem that the slider 30 can slide to open the lid 10 when subjected to a small force when the float 50 floats.

Preferably, as shown in FIG. 5 and FIG. 6 , 21 of the guide member 20 is disposed with a first limiting slot 25 corresponding to the position of the float 50 , and the slider 30 includes a first end 31 corresponding to the float 50 , and the first end 31 . Sliding within the first limit slot 25 thus defines the sliding of the first end 31 of the slider 30. It is worth mentioning that the limiting portion of the slider 30 can also be disposed at the first end 31. For example, the limiting portion can be set as a through hole at the first end 31, and when the float 50 floats, it just snaps into the through hole. In the hole, so that the slider 30 can not slide, the purpose of the limit is reached.

Further, as shown in FIG. 5 and FIG. 6 , the second guiding portion 22 is disposed with a second limiting slot 26 corresponding to the position of the self-locking pin 40 , and the slider 30 includes a second end 32 corresponding to the self-locking pin 40 , The second end 32 slides within the second limiting slot 26. Typically, the second end 32 of the slider 30 is disposed opposite the first end 31 such that after defining the movement of the first end 31, the second end 32 is again defined. The motion can effectively define the motion of the slider 30.

In an embodiment of the invention, the setting slider 30 includes a second connecting portion 33 connecting the first end 31 and the second end 32, in order to further define the movement of the slider 30, as shown in FIGS. 5 and 6, A limiting cavity 27 is formed in the first connecting portion 23 for sliding the second connecting portion 33. The first limiting slot 25 and the second limiting slot 26 communicate through the limiting cavity 27 and form together with the limiting cavity 27. The guiding cavity, as such, defines the movement space of the entire slider 30 through the guide member 20, ensures that the slider 30 is moved to an accurate position, prevents the deviation of its movement, and the problem that the pressure cooker can be forcibly opened with a small force.

Specifically, the first guiding portion 21 may include a first body (not labeled) and two first side plates (not labeled). The two first side plates may be respectively disposed on the two side edges of the first body, and the two first side plates may respectively extend upward from the two side edges of the first body, such that the first guiding portion 21 defines The first limiting slot 25 can limit the degree of freedom of the horizontal swing of the slider 30; further, the first guiding portion 21 can further include two longitudinal limiting pieces (not labeled), and the two longitudinal limiting pieces can respectively And connecting the upper edges of the two first side plates, and the two longitudinal limiting pieces may extend from the upper edges of the two first side plates toward the first body, respectively. In this way, the two longitudinal limiting piece stop sliders 30 can be moved upward, and the first body can stop the sliding block 30 to move downward, thereby limiting the degree of freedom of the sliding movement of the sliding block 30, thereby finally achieving the passage. The first limiting groove 25 of a guiding portion 21 realizes the degree of freedom of restricting the upward movement of the slider 30 and the degree of freedom of horizontal swing. Of course, in other embodiments, the degree of freedom of the up and down movement of the slider 30 and the degree of freedom of horizontal swing can also be limited by setting the structure of the limiting cavity 27.

Generally, after the slider 30 is mounted to the guiding cavity, when the first end 31 of the slider 30 moves in the first limiting slot 25, the end (not labeled) of the first end 31 of the slider 30 is due to the entire slider 30. Gravity is prone to the problem of upturning. At this time, the limit action of the float 50 may be invalid due to the upward end of the first end 31, and there is a problem that the pressure cooker is forcibly opened with a small force. To this end, the first limiting slot 25 is provided in the present invention, and includes an end limiting portion (not labeled) corresponding to the end of the first end 31 of the slider 30 for defining the end movement of the end of the first end 31 The degree of freedom. Specifically, the end limiting portion is a sub-structure of the first limiting slot 25, which is also a limiting slot. For example, a radial limiting piece (not labeled) is disposed on the inner edge of the first body. The radial limiting piece may extend upward from the inner edge of the first body, wherein the inner edge of the first body refers to the edge adjacent to the inside of the lid assembly; meanwhile, the third longitudinal limiting piece is disposed at the edge of the radial limiting piece The third longitudinal limiting piece extends toward the first body. Thus, the first body, the radial limiting piece and the third longitudinal limiting piece form a limiting slot, wherein the third longitudinal limiting piece is The end of the first end 31 of the stop slider 30 can be moved upward, and the first body can stop the end of the first end 31 from moving downward, whereby the end limit portion can limit the up and down movement of the end of the first end 31. The free end effectively prevents the tip end of the first end 31 from being warped. Of course, in other embodiments, the degree of freedom of the up and down movement of the end of the first end 31 of the slider 30 can also be limited by providing a limiting slot with the opening downward.

Generally, the end limit portion is generally disposed on one side of the float 50. In order to ensure the stability of the degree of freedom of restricting the movement of the slider in the first limit groove 25, the first limit groove 25 is further provided with a second sub-limit. a slot, the second sub-limit slot and the end limit slot are oppositely disposed on opposite sides of the float 50, and the second sub-limit slot is used for limiting the degree of freedom of the slider to move up and down and the degree of freedom of horizontal swing, and the structure thereof The structure of the first guide portion 21 described above can be referred to.
