[0028] In some embodiments, The mesh cover fixing frame 2 comprises a mounting bottom plate 7 and an annular side plate 8, the mounting bottom plate 7 is connected with the first side end face 9 of the cover plate 1, the annular side plate 8 is connected with the periphery of the mounting bottom plate 7 and protrudes away from the cover plate 1 to enclose an internal space 11, the third exhaust hole 6 is opposite to and in communication with the internal space 11, and the second exhaust hole 5 is arranged on the mounting bottom plate 7 in a manner of penetrating through both side faces of the mounting bottom plate 7; The anti-blocking mesh cover 3 can rotate to open the inner space 11 of the mesh cover fixing frame 2 when cleaning is needed, and can rotate to close the inner space 11 of the mesh cover fixing frame 2 when working normally.

[0029] The application further forms an inner space by arranging the mesh cover fixing frame to include a ring-shaped side plate and a mounting bottom plate, and protruding the inner space towards the first side end surface of the cover plate (usually towards the inner part of the pot body), and the cross-sectional area of the inner space is preferably larger than the flow cross-sectional area of the first exhaust hole, so that the exhaust flow area is effectively increased, and the anti-blocking performance of the exhaust is further improved.

[0034] In some embodiments, The anti-blocking mesh cover 3 further includes a guide part 18 connected to the second clamping part 17, and the guide part 18 has a guide inclined surface; and the mounting bottom plate 7 and the cover plate 1 are riveted and fixed by a rivet 19.

[0035] The anti-blocking cover can be clamped and guided through the guide portion when being covered to the inside of the annular side plate, and finally clamped through the first and second clamping portions, so that the assembly of small flow is improved.

[0036] In some embodiments, The annular side plate 8 is further provided with fourth exhaust holes 12 penetrating the annular side plate 8 to communicate the internal space 11 at the inner periphery of the annular side plate 8 with the space at the outer periphery of the annular side plate 8, and the third exhaust holes 6 and the fourth exhaust holes 12 are both multiple.

[0037] The fourth exhaust holes provided on the annular side plate can further increase the exhaust flow area of the anti-blocking cover assembly, and further improve the performance of the pressure rice cooker in preventing blocking of exhaust.

[0038] In order to improve the safety of pressure rice cooking, food safety and user cleaning and maintenance, the application designs a new anti-blocking cover which mainly comprises a mesh cover, a mesh cover fixing frame, a hinge shaft and other main parts. The mesh cover and the mesh cover fixing frame are hinged by the hinge shaft and can be opened and closed to prevent the loss of parts during user cleaning. The mesh cover and the mesh cover fixing frame have multiple circular and strip-shaped holes on multiple surfaces to prevent the exhaust valve hole from being blocked during pressure cooking. The application selects non-plastic parts which are resistant to aging in high temperature and high pressure environment during cooking and have better food safety In some embodiments, Further comprising an exhaust valve 20, an exhaust valve seat one 21 and an exhaust valve seat two 22, the exhaust valve seat one 21 and the exhaust valve seat two 22 are both arranged on the second side end face 10 of the cover plate 1, the second side end face 10 and the first side end face 9 are two end faces opposite to each other of the cover plate 1, the exhaust valve seat one 21 has a fifth exhaust hole 23 opposite to the first exhaust hole 4, the exhaust valve seat two 22 covers at least part of the structure of the exhaust valve seat one 21, the exhaust valve seat one 21 has an inner cavity 24, at least part of the structure of the exhaust valve seat one 21 is located in the inner cavity 24, the exhaust valve 20 is arranged in the inner cavity 24 and located between the exhaust valve seat one 21 and the exhaust valve seat two 22, the exhaust valve 20 can close the fifth exhaust hole 23 by its gravity and the connection with the fifth exhaust hole 23, when the pressure of the first exhaust hole 4 is greater than the gravity of the exhaust valve 20, the exhaust valve 20 is separated from the fifth exhaust hole 23, so that the first exhaust hole 4, the fifth exhaust hole 23 and the inner cavity 24 are sequentially communicated.

[0039] The application further forms an inner cavity containing the exhaust valve between the two exhaust valve seats arranged on the second side end face of the cover plate, and drives the exhaust valve to move according to the pressure to open or close the exhaust passage, and the two exhaust valve seats are both fixed to the cover plate, which can form a two-layer sealing effect on the first exhaust hole of the cover plate and prevent exhaust leakage.

[0040] In some embodiments, The exhaust valve seat two 22 is further provided with a sixth exhaust hole 25, when the pressure of the first exhaust hole 4 is greater than the gravity of the exhaust valve 20, the first exhaust hole 4, the fifth exhaust hole 23, the inner cavity 24 and the sixth exhaust hole 25 are sequentially communicated to exhaust.

[0041] This is the preferred structure of the exhaust valve seat two of the application, which can effectively communicate the gas in the inner cavity through the sixth exhaust hole to form a communication passage for outward exhaust.

The exhaust valve support two is in sealed contact with at least a portion of the outer periphery of the exhaust valve support one. The exhaust valve support two is also fixed as a whole with the cover plate and the mesh cover fixing frame, which further enhances the sealing performance of the exhaust port and prevents gas from leaking to the outside of the exhaust valve assembly.

[0044] The present invention also provides a pressure rice cooker, which includes the aforementioned pressure rice cooker exhaust anti-clogging component 100, and also includes a lid 101 and a cooker body 102, wherein the lid plate 1 is located on the lid 101.

[0045] like Figure 1 As shown, the inner pot of this pressure cooker bears pressure during cooking and requires intermittent venting according to cooking requirements. The pot opening is sealed by a lid assembly. Hot steam follows the path shown in the diagram, passing through the anti-clogging cover assembly on the lid assembly and the vent valve before being discharged through the top vent. Because the pressure cooker operates under pressure, venting can easily cause soup and food to spray out together. To avoid this problem, the lid assembly needs to be equipped with an anti-clogging cover. like Figures 4-5 The image shows the mesh cover of the present invention in both closed and open states. The mesh cover has round holes and strip-shaped holes (third vent holes), and the mesh cover fixing frame has round holes on its side (fourth vent holes), all of which are used for venting and filtering to prevent food from clogging the vent valve holes.

[0046] The beneficial effects of this invention are: 1. The hinge connection prevents parts from being lost during the cleaning process.

[0047] 2. The anti-clogging cover has a large filter hole coverage area, with round holes and strip ribs distributed on multiple surfaces, which greatly reduces the possibility of clogging.

[0048] 3. Made of food-grade stainless steel, it resists aging under high temperature and pressure conditions, ensuring food safety. The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
