[0062] The present invention provides a bubble breaker assembly, which is applied to the lid assembly of an electric pressure cooker and can improve the anti-overflow and silent effect of the electric pressure cooker.

[0063] Please refer to Figures 2 to 4 , Figure 15 and Figure 16In one embodiment of the present invention, the bubble breaker assembly 15 includes a bubble breaker base 151 and a bubble breaker cover 153, the bubble breaker base 151 is formed with a buckle groove 151a and a first exhaust hole 1515a connected to the buckle groove 151a; the bubble breaker cover 153 covers at least a portion of the bubble breaker base 151, and is enclosed with a side of the bubble breaker base 151 away from the opening of the buckle groove 151a to form a first buffer space 15a, the first buffer space 15a is connected to the first exhaust hole 1515a, and the bubble breaker cover 153 is provided with a second exhaust hole 1531a connected to the first buffer space 15a.

[0064] In this embodiment, the bubble breaker assembly 15 is arranged on the top of the pot cover body 11 of the pot cover assembly 10, and covers the exhaust assembly 13 of the pot cover assembly 10. When the electric pressure cooker 100 is exhausted, the airflow first passes through the bubble breaker assembly 15 and then flows out to the outside, so that the bubbles can be broken and the liquid can be prevented from flowing out. Of course, the bubble breaker assembly 15 here is not limited to being arranged in conjunction with the exhaust assembly 13, and can also be directly adapted to the exhaust port 111 of the pot cover body 11. Specifically, the bubble breaker assembly 15 includes a bubble breaker base 151 and a bubble breaker cover 153. The bubble breaker base 151 itself forms a buckle groove 151a with a larger space. The buckle groove 151a can be connected with the pot cover body 11 when it is connected and matched, and the pot cover body 11 is enclosed to form a primary buffer space for steam, reduce the speed and pressure of the airflow, and enter the first buffer space 15a after passing through the first exhaust hole 1515a. The structure is simple and does not require too many connection relationships. Here, the first exhaust hole 1515a also plays a role in breaking bubbles. When the airflow discharged from the exhaust component 13 contains liquid such as rice soup, when the airflow passes through the first exhaust hole 1515a after buffering, the bubbles are squeezed and broken by the first exhaust hole 1515a, thereby trapping most of the liquid. The bubble breaker cover 153 covers the bubble breaker base 151, and the connection between the two can be a detachable connection, such as a snap-on, plug-in, etc., so as to facilitate disassembly and installation, which is conducive to improving the convenience of cleaning and preventing steam from flowing through the bubble breaker for a long time to generate bacteria.

[0065] Here, the bubble breaker base 151 and the bubble breaker cover 153 can both be made of plastic material and can be easily processed and cleaned by injection molding. The cross-sectional shape of the bubble breaker base 151 can be circular, square or other shapes, which are not limited here. The bubble breaker cover 153 is adapted to the shape of the bubble breaker base 151, so as to facilitate assembly and increase the capacity of the first buffer space 15a. The shapes of the first exhaust hole 1515a and the second exhaust hole 1531a can be circular, square, long strip or other shapes, etc., which are not limited here.

[0066] The bubble breaker assembly 15 of the technical solution of the present invention includes a bubble breaker base 151 and a bubble breaker cover 153. The bubble breaker base 151 is formed with a buckle groove 151a, which can form a preliminary buffer space when the bubble breaker assembly 15 is installed on the electric pressure cooker 100, so that the high-pressure steam discharged from the pot can effectively reduce the air flow pressure and speed when passing through the buffer space formed by the buckle groove 151a, and then discharged into the first buffer space 15a formed by the bubble breaker base 151 and the bubble breaker cover 153 through the first exhaust hole 1515a, further reducing the air flow speed and pressure, and then discharged to the outside through the second exhaust hole 1531a. In this way, after the high-pressure steam passes through the two buffer spaces and the two-stage exhaust holes, its pressure and speed are effectively reduced, and the bubbles are squeezed through the two-stage exhaust holes, so that the liquid is trapped in the bubble breaker assembly 15 to prevent the liquid from overflowing; and after the noise reduction of the two buffer spaces, the noise reduction effect can be effectively improved.

[0067] Please combine Figures 4 to 7 In one embodiment of the present invention, the bubble breaker base 151 includes a first baffle 1511, a first enclosure 1513 and a second baffle 1515, the first enclosure 1513 is formed by bending and extending the periphery of the first baffle 1511, the second baffle 1515 is arranged on the outer peripheral surface of the first enclosure 1513, the first baffle 1511, the first enclosure 1513 and the second baffle 1515 are combined to form the buckle groove 151a, the second baffle 1515 is provided with the first exhaust hole 1515a, and the bubble breaker cover 153 is connected to the second baffle 1515.

[0068] In this embodiment, in order to achieve a significant effect of reducing the airflow pressure, the bubble breaker base 151 includes a first baffle 1511, a first enclosure 1513 and a second baffle 1515. The first baffle 1511 and the first enclosure 1513 enclose an airflow buffer space that cooperates with the exhaust component 13, that is, a part of the buckle groove 151a, so that the airflow coming out of the exhaust component 13 releases pressure through the buffer space here. At the same time, the second baffle 1515 is also connected to the circumference of the first enclosure 1513. Optionally, the second baffle 1515 is arranged in parallel with the first baffle 1511, and the appearance is neat and convenient for processing. The second baffle 1515 can be arranged to expand the space of the buckle groove 151a, thereby increasing the initial buffer space of the airflow. In this way, after passing through the narrow space of the exhaust component 13 and entering the larger space of the buffer space, the airflow pressure and speed can be quickly reduced, and the noise reduction effect is obvious. The first exhaust hole 1515a is arranged on the second baffle plate 1515, while the first baffle plate 1511 and the first enclosure plate 1513 have no air holes, so that the airflow can flow through the second baffle plate 1515, reduce pressure and noise, and then be discharged outward through the first exhaust hole 1515a, thereby further improving the effect of reducing pressure and noise.

[0069] Here, the first baffle 1511, the first enclosing plate 1513, and the second baffle 1515 are of an integrally formed structure, which is integrally formed by injection molding, thereby effectively improving the structural strength and stability of the bubble breaker base 151, and can reduce gaps to avoid air flow disorder and further reduce noise. Optionally, the first enclosing plate 1513 is formed by bending and extending from the periphery of the first baffle 1511, and the second baffle 1515 is disposed on the outer peripheral surface of the first enclosing plate 1513, and can be flush with the edge of the first enclosing plate 1513, or can be disposed at the middle position or other positions of the first enclosing plate 1513, which is not limited herein. The first baffle 1511 is in the shape of a circular plate, the first enclosing plate 1513 is in the shape of a circular ring, and the second baffle 1515 is also in the shape of a circular ring plate, so that the opening shape of the buckle groove 151a formed is circular, smooth and without sharp corners, which is convenient for cleaning and holding, and can make the air flow smoothly and reduce noise generation. Of course, the bubble breaker base 151 here is also adapted to the cylindrical exhaust assembly 13.

[0070] Please continue to refer to Figure 7 In an embodiment of the present invention, the bubble breaker base 151 further includes a second enclosing plate 1517, and the second enclosing plate 1517 is annularly disposed around the periphery of the second baffle 1515, and the second enclosing plate 1517, the second baffle 1515, the first enclosing plate 1513, and the first baffle 1511 jointly enclose to form the buckle groove 151a.

[0071] In this embodiment, in order to prevent the air flow from flowing to other corners through the edge of the second baffle 1515 and causing blockage, a second enclosing plate 1517 is further disposed on the periphery of the second baffle 1515, and the second enclosing plate 1517 is in the shape of an annular enclosing plate when the first baffle 1511 is in the shape of a circular ring. The second enclosing plate 1517 is also of an integrally formed structure with the second baffle 1515, thereby reducing air flow leakage and improving the structural strength of the bubble breaker base 151, and can facilitate the connection of the bubble breaker base 151 with the pot lid body 11. In this way, when the buckle groove 151a enclosed by the first enclosing plate 1513, the first baffle 1511, the second baffle 1515, and the second enclosing plate 1517 cooperates with the pot lid body 11, a buffer space with a larger space can be formed, and it can be ensured that the air flow all passes through the first exhaust hole 1515a, avoiding the situation of air flow chaos and reducing noise generation.

[0072] In an embodiment of the present invention, a plurality of the first exhaust holes 1515a are provided, and the plurality of first exhaust holes 1515a are spaced apart and disposed on the second baffle 1515;

[0073] And / or, the diameter of the first exhaust hole 1515a is D1, wherein the range of D1 is greater than or equal to 1 mm and less than or equal to 5 mm.

[0074] In this embodiment, in order to improve the discharge rate of the air flow, a plurality of first exhaust holes 1515a are provided. The plurality of first exhaust holes 1515a are spaced apart on the second baffle 1515. For example, they can be arranged in a ring or a fan shape around the periphery of the first enclosure 1513. Moreover, the plurality of first exhaust holes 1515a can be centrosymmetrically distributed about the center of the second baffle 1515, so that the pressure at each position of the second baffle 1515 is equal, avoiding structural deformation or impact damage caused by excessive local pressure. Of course, in other embodiments, the plurality of first exhaust holes 1515a can also be arranged in a radial arrangement or a straight arrangement along the second baffle 1515, etc. The arrangement of the plurality of first exhaust holes 1515a can prevent the air flow from having a large impact on the initial buffer space when the pressure of the air flow is too large, and can quickly release the air flow so that it enters the first buffer space 15a, improving the effect of pressure reduction and noise reduction. The number of the first exhaust holes 1515a can be adjusted according to the size of the bubble breaker assembly 15.

[0075] Here, on the basis of one, two or more first exhaust holes 1515a, the shape of the first exhaust hole 1515a can be set as a circle, which is convenient for processing and can be adapted to the bubbles, facilitating the breaking of the bubbles. Of course, the diameter of the first exhaust hole 1515a should not be too small, otherwise it will block the outflow of the air flow and increase the air pressure in the buckle groove 151a; the diameter of the first exhaust hole 1515a should not be too large, otherwise it will not achieve the effect of buffering the air flow. Therefore, the diameter of the first exhaust hole 1515a is set as D1 here, and the value range of D1 is greater than or equal to 1 mm and less than or equal to 5 mm. For example, 2 mm, 3 mm, 4 mm, etc., so as to prevent the air flow from being blocked and ensure the smooth outflow of the air flow after buffering, and also avoid the air flow flowing out without being buffered, effectively ensuring the effect of pressure reduction and noise reduction of the air flow.

[0076] Please refer to again Figure 7 , in an embodiment of the present invention, one end of the first enclosure 1513 away from the first baffle 1511 protrudes from the second baffle 1515, and the height of the first enclosure 1513 protruding from the second baffle 1515 is greater than the height of the second enclosure 1517 protruding from the second baffle 1515.

[0077] In this embodiment, in order to further improve the buffer space for the air flow to enter the position of the second baffle 1515, the second baffle 1515 is arranged at a position slightly below the middle of the first surrounding plate 1513, that is, the edge of the first surrounding plate 1513 protrudes from the surface of the second baffle 1515 facing away from the first baffle 1511. In this way, on the one hand, the first surrounding plate 1513 can be adapted to the exhaust assembly 13, and the air flow discharged from the exhaust assembly 13 can be guided to the surface close to the pot lid body 11, so as to slowly pass through the gap between the edge of the first surrounding plate 1513 and the pot lid body 11 and enter the buffer space at the position of the second baffle 1515, further improving the effect of reducing the air pressure; on the other hand, without increasing the volume of the bubble breaker base 151, the capacity of the buffer space communicated with the first exhaust hole 1515a can be increased, further improving the pressure reduction effect.

[0078] Meanwhile, the height by which the first surrounding plate 1513 protrudes from the first baffle 1511 is greater than the height by which the second surrounding plate 1517 protrudes from the first baffle 1511, so that it can be adapted to other structures, further increasing the preliminary buffer space and effectively improving the decompression and noise reduction effects.

[0079] Please refer to Figure 4 , Figures 11 to 13 , in an embodiment of the present invention, the bubble breaker cover 153 includes a cover plate 1531 and side plates 1533 arranged on the periphery of the cover plate 1531. The cover plate 1531 and the side plates 1533 enclose a cover groove 153a. The inner wall of the cover groove 153a is connected to the second baffle 1515. The second baffle 1515, the first surrounding plate 1513 and the cover plate 1531 enclose the first buffer space 15a. The cover plate 1531 is provided with the second exhaust hole 1531a.

[0080] In this embodiment, the bubble breaker cover 153 includes a cover plate 1531 and side plates 1533. The cover plate 1531 and the side plates 1533 enclose a cover groove 153a, and its structural shape is generally U-shaped. It is covered on the bubble breaker base 151 and encloses the first buffer space 15a with the bubble breaker base 151. The air flow entering the first buffer space 15a from the first exhaust hole 1515a can be further buffered, decompressed and noise-reduced. Here, the cover plate 1531 and the side plates 1533 can be an integrally formed structure or a split structure, which is not limited herein.

[0081] The bubble breaker cover 153 is connected to the bubble breaker base 151. Here, the inner wall of the cover groove 153a is connected to the second baffle 1515, and the edge of the side plate 1533 is connected to the pot lid body 11, so that there is a gap for air flow between the edge of the first enclosure 1513 and the pot lid body 11, and the preliminary buffer space can be increased. In this way, the cover plate 1531, the second baffle 1515 and the first enclosure 1513 enclose to form the first buffer space 15a. The second exhaust hole 1531a is arranged on the cover plate 1531, so that the air flow passes through the first buffer space 15a and then is discharged to the outside from the second exhaust hole 1531a, effectively improving the buffer, pressure reduction and noise reduction effects. Of course, in other embodiments, the edge of the side plate 1533 can also be connected to the second baffle 1515 or the second enclosure 1517, and the second enclosure 1517 is connected to the pot lid body 11.

[0082] In addition, for a smooth appearance, chamfering is provided at the docking position of the cover plate 1531 and the side plate 1533, or the edge of the cover plate 1531 is inclined, or the edge of the side plate 1533 is inclined, or the edges of the cover plate 1531 and the side plate 1533 are both inclined, so that there are no sharp edges on the outer surface of the bubble breaker cover 153, improving the convenience and safety of use.

[0083] Please refer to Figure 11 、 Figures 20 to 22 , in an embodiment of the present invention, the cover plate 1531 is provided with an avoidance hole 1531b, and the first baffle 1511 and part of the first enclosure 1513 pass through the avoidance hole 1531b; the second exhaust hole 1531a is communicated with the avoidance hole 1531b; or, the second exhaust hole 1531a is arranged at an interval from the avoidance hole 1531b.

[0084] In this embodiment, in order to reduce the overall structural volume of the bubble breaker assembly 15, an avoidance hole 1531b is opened in the middle of the cover plate 1531, and the first baffle 1511 and part of the first enclosure 1513 pass through the avoidance hole 1531b, so that the height of the side plate 1533 can be reduced, and the appearance of the first baffle 1511 is exposed outside, improving the overall aesthetics of the bubble breaker assembly 15. With reference to Figures 14 to 16 , in one embodiment, the surface of the first baffle 1511 is a smooth surface, and in another embodiment, the surface of the first baffle 1511 is provided with a plurality of circular angular lines.

[0085] On the basis of providing the second exhaust hole 1531a and the avoidance hole 1531b, in one embodiment, the second exhaust hole 1531a can be communicated with the avoidance hole 1531b, that is, the second exhaust hole 1531a is formed at the edge of the avoidance hole 1531b. In this way, the air flow flows out from the gap between the first shroud 1513 and the second exhaust hole 1531a. The provision of this structure can facilitate the cleaning of the bubble breaker cover 153. In another embodiment, the second exhaust hole 1531a and the avoidance hole 1531b can be arranged at intervals, that is, there is a certain distance between the hole edges of the second exhaust hole 1531a and the avoidance hole 1531b. This structure can effectively ensure the size of the second exhaust hole 1531a and improve the smoothness of the air flow out.

[0086] In one embodiment of the present invention, a plurality of the second exhaust holes 1531a are provided, and the plurality of the second exhaust holes 1531a are arranged at intervals along the circumferential direction of the cover plate 1531;

[0087] And / or, the second exhaust hole 1531a extends along the circumferential direction of the cover plate 1531, and the width of the second exhaust hole 1531a in the radial direction of the cover plate 1531 is B1, where the range of B1 is greater than or equal to 2 mm and less than or equal to 8 mm.

[0088] In this embodiment, a plurality of the second exhaust holes 1531a are provided, which can improve the smoothness of the air flow out. After being buffered by two-stage buffer spaces, both the air flow pressure and the speed are reduced to a suitable range. Therefore, the provision of a plurality of the second exhaust holes 1531a can improve the effect of pressure reduction and noise reduction. Moreover, the plurality of the second exhaust holes 1531a are arranged at intervals along the circumferential direction of the cover plate 1531, which can improve the uniformity of the air flow and ensure uniform pressure on the bubble breaker cover 153, avoiding local pressure deformation or noise concentration. The number of the second exhaust holes 1531a can be adjusted according to the size of the bubble breaker assembly 15. Of course, the plurality of the second exhaust holes 1531a can also be arranged in a straight row.

[0089] On the basis that the number of the second exhaust holes 1531a is one, two or more, the shape of the second exhaust holes 1531a is set to be strip-shaped, and the length of the second exhaust holes 1531a extends along the circumferential direction of the cover plate 1531 and is arranged in an arc shape, so as to be adapted to the peripheral edge of the first shroud 1513. Since the pressure and speed of the air flow drop sharply after being buffered by the first buffer space 15a, the opening size of the second exhaust holes 1531a can be larger than that of the first exhaust holes 1515a without affecting the buffering effect. The length and number of the second exhaust holes 1531a in the circumferential direction of the cover plate 1531 can be determined according to the size of the bubble breaker assembly 15. Here, the number of the second exhaust holes 1531a communicated with the avoidance holes 1531b is set to be three, and the number of the second exhaust holes 1531a not communicated with the avoidance holes 1531b is set to be six. The width of the second exhaust holes 1531a in the radial direction of the cover plate 1531 is B1, and the value range of B1 is greater than or equal to 2 mm and less than or equal to 8 mm. For example, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, etc., so as to effectively improve the smoothness of the air flow out.

[0090] In an embodiment of the present invention, the cover plate 1531 and the side plate 1533 are fixedly connected; and / or, the material of the cover plate 1531 is a transparent material.

[0091] Here, the cover plate 1531 and the side plate 1533 are set as two separate components, which are processed separately and then assembled. Here, in order to improve the connection stability between them, they can be set as fixedly connected, for example, bonded or welded, etc., so as to effectively improve the connection tightness between them and avoid air leakage. Here, the cover plate 1531 and the side plate 1533 can be processed with materials of different materials respectively and matched with different colors, which can effectively improve the appearance and increase the recognition. Of course, in other embodiments, the cover plate 1531 and the side plate 1533 can also be set as detachably connected.

[0092] Optionally, the material of the cover plate 1531 is set as a transparent material, that is, the cover plate 1531 is a transparent part, for example, polymethyl methacrylate (PMMA, acrylic plate), polystyrene (PS), polycarbonate (PC), etc., which is not limited here. In this way, the dirt condition inside the bubble breaker assembly 15 can be observed through the cover plate 1531 at any time, so that the user can clean it in time and improve the safety and hygiene of the bubble breaker assembly 15.

[0093] Please combine Figure 4 、 Figures 8 to 10In order to further improve the appearance and noise reduction effect, in one embodiment of the present invention, the bubble breaker assembly 15 also includes a bubble breaker grid 155, and the bubble breaker grid 155 is arranged in the first buffer space 15a and has a third exhaust hole 1555a connected to the first buffer space 15a.

[0094] In this embodiment, the bubble breaker grid 155 is arranged in the first buffer space 15a, and a third exhaust hole 1555a is provided. The third exhaust hole 1555a runs through the thickness direction of the bubble breaker grid 155, that is, it is connected to the first buffer space 15a, so that the airflow enters the first buffer space 15a after passing through the first exhaust hole 1515a, and flows to the second exhaust hole 1531a through the third exhaust hole 1555a, which does not affect the buffering effect of the airflow in the first buffer space 15a; at the same time, it can also play a certain guiding role in the routing of the airflow, avoid airflow turbulence in the first buffer space 15a, and further reduce noise. The shape of the third exhaust hole 1555a can be a long strip, a circle or other shapes, which are not limited here. In addition, the bubble breaker grid 155 can also be exposed through the second exhaust hole 1531a to increase the layered appearance.

[0095] In one embodiment of the present invention, the bubble breaker grid 155 includes an inner ring plate 1551, an outer ring plate 1553 and a connecting piece 1555 connecting the inner ring plate 1551 and the outer ring plate 1553, the connecting piece 1555 forms the third exhaust hole 1555a, and the outer ring plate 1553 is installed on the side of the bubble breaker base 151 away from the opening of the buckle groove 151a and / or the inner wall surface of the bubble breaker cover 153.

[0096] Specifically, the bubble breaker grid 155 includes an inner ring plate 1551 and an outer ring plate 1553. The inner ring plate 1551 is an annular plate arranged around the periphery of the first enclosure 1513, and the inner ring plate 1551 extends along the axial direction of the first enclosure 1513, and its inner diameter is adapted to the outer diameter of the first enclosure 1513, so as to facilitate assembly. The outer ring plate 1553 is arranged in parallel with the inner ring plate 1551, and is located on the surface of the second baffle 1515 away from the second enclosure 1517, and can be connected to the second baffle 1515, or connected and fixed to the inner wall surface of the cover groove 153a. Between the inner ring plate 1551 and the outer ring plate 1553 is a connecting member 1555 connecting the two, and the connecting member 1555 is provided with a third exhaust hole 1555a, so that the airflow passes through the first buffer space 15a. Here, a plurality of third exhaust holes 1555a are provided, that is, the connecting member 1555 is formed with a plurality of the third exhaust holes 1555a, and the plurality of third exhaust holes 1555a are arranged in an array at intervals, so as to further reduce the influence on the air flow.

[0097] Please refer again Figure 7 andFigure 8 In an embodiment of the present invention, a mounting plate 1519 is formed on the surface of the second baffle 1515 facing away from the second enclosing plate 1517. The mounting plate 1519 and the second baffle 1515 enclose to form a mounting groove 151b. The outer ring plate 1553 is fixed in the mounting groove 151b, and the inner wall surface of the bubble breaker cover 153 is connected to the mounting plate 1519.

[0098] In this embodiment, for the convenience of assembly, a mounting plate 1519 is convexly provided on the surface of the second baffle 1515 facing the bubble breaker grille 155. The mounting plate 1519 is arranged along the periphery of the second baffle 1515 and encloses with the second baffle 1515 to form a mounting groove 151b. The outer ring plate 1553 can be fixed in the mounting groove 151b, so that the installation of the bubble breaker grille 155 is more convenient and rapid. Here, the mounting plate 1519 is in the shape of an annular plate, so as to increase the installation space of the mounting groove 151b. Of course, in other embodiments, the mounting plate 1519 can also be arranged as a plurality of arc-shaped plate structures with smaller sizes.

[0099] In addition, the height of the outer ring plate 1553 can be higher than that of the mounting plate 1519. The inner wall surface of the bubble breaker cover 153 abuts against the outer peripheral wall of the outer ring plate 1553 and the end surface of the mounting plate 1519, so as to form a stable connection structure, and the structure can be simplified, avoiding a relatively high height of the mounting plate 1519 and a relatively large thickness of the cover plate 1531. Of course, in other embodiments, the height of the mounting plate 1519 can also be higher than that of the outer ring plate 1553, and the convex structure on the inner wall surface of the covering groove 153a abuts against the outer peripheral surface of the mounting plate 1519.

[0100] Please combine Figure 5 and Figure 8 In an embodiment of the present invention, in order to further improve the connection stability, a clamping groove 151c and a clamping inlet 151d are formed on the peripheral wall of the mounting groove 151b. The clamping inlet 151d communicates with one groove wall of the clamping groove 151c. A clamping block 1557 is formed on the periphery of the outer ring plate 1553. The clamping block 1557 is screwed into and fixed in the clamping groove 151c through the clamping inlet 151d.

[0101] In this embodiment, the peripheral wall of the installation groove 151b is bent away from the center of the second baffle 1515 to form a clamping groove 151c, and the side wall of the clamping groove 151c parallel to the surface of the first baffle 1511 is opened to form a clamping inlet 151d. A clamping block 1557 is formed on the outer peripheral edge of the outer ring plate 1553. When the outer ring plate 1553 is installed in the installation groove 151b, the clamping block 1557 is adapted to the clamping inlet 151d. Then, the bubble breaker grille 155 is rotated to snap the clamping block 1557 into the clamping groove 151c for fixation, thereby limiting the axial direction of the bubble breaker grille 155 and ensuring the stability of the connection structure. Moreover, the connection method is simple and fast, improving the assembly efficiency.

[0102] Please refer to again Figure 8 , in an embodiment of the present invention, the connecting member 1555 includes a plurality of rib plates 1559, and each rib plate 1559 extends along the radial direction of the outer ring plate 1553. The plurality of rib plates 1559 are spaced apart in the circumferential direction of the outer ring plate 1553, and the third exhaust holes 1555a are formed by enclosing between two adjacent rib plates 1559.

[0103] Here, the connecting member 1555 is formed by a plurality of rib plates 1559. The rib plates 1559 are in the shape of long strip plates and extend along the radial direction of the outer ring plate 1553, that is, one end of the rib plate 1559 is connected to the inner ring plate 1551, and the other end is connected to the outer ring plate 1553. The plurality of rib plates 1559 are spaced apart in the circumferential direction of the outer ring plate 1553. The surfaces of two adjacent rib plates 1559 are relatively arranged and enclose to form the third exhaust holes 1555a, that is, the surfaces of the rib plates 1559 form the inner wall of the holes of the third exhaust holes 1555a. When the air flow passing through the first exhaust hole 1515a passes through the first three exhaust holes, it can guide the air flow to flow along the axial direction of the bubble breaker assembly 15, avoiding the disorder and turbulence of the air flow in the entire first buffer space 15a to eliminate the extra noise generated by the air flow. At the same time, when the bubbles flowing through the first exhaust hole 1515a still contain liquid, the second exhaust hole 1531a can further squeeze to break the bubbles, further reducing the liquid overflow.

[0104] Please refer to Figures 17 to 19 , in an embodiment of the present invention, the connecting member 1555 further includes a transition portion 1558. The transition portion 1558 extends along the peripheral edge of the outer ring plate 1553 in a bent manner. One end of each rib plate 1559 is connected to the outer surface of the inner ring plate 1551, and the other end is connected to the inner surface of the transition portion 1558;

[0105] And / or, the width of the third exhaust hole 1555a in the circumferential direction of the connecting member 1555 is B2, where the value range of B2 is greater than or equal to 2 mm and less than or equal to 8 mm.

[0106] Different from the bubble breaker grille 155 of the previous embodiment, the connecting member 1555 of the bubble breaker grille 155, in addition to having rib plates 1559, also includes a transition portion 1558. The transition portion 1558 bends and extends along the circumference of the outer ring plate 1553 and is arranged in an arc-shaped plate on the longitudinal section of the bubble breaker grille 155, thereby reducing the length of the rib plates 1559. One end of each rib plate 1559 is connected to the outer surface of the inner ring plate 1551, and the other end is connected to the inner surface of the transition portion 1558. In this way, the structure of the bubble breaker grille 155 is more stable. Of course, in other embodiments, the transition portion 1558 can also be arranged at the edge of the inner ring plate 1551, so that one end of the rib plate 1559 is connected to the edge of the transition portion 1558, and the other end is connected to the inner surface of the outer ring plate 1553.

[0107] Based on the structure of the bubble breaker grille 155 with or without the transition portion 1558, in order to buffer the airflow, the width of the third exhaust hole 1555a should not be too large. At the same time, for the convenience of the airflow passing through, the width of the third exhaust hole 1555a should not be too small. Therefore, the width of the third exhaust hole 1555a in the circumferential direction of the connecting member 1555 is set to B2 here, and the range value of B2 is greater than or equal to 2 mm and less than or equal to 8 mm. For example, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, etc., which can ensure the buffering and bubble-breaking effect of the third exhaust hole 1555a and also facilitate the airflow. Here, because the diameters of the inner ring plate 1551 and the outer ring plate 1553 are different, the distance between adjacent rib plates 1559 will increase in the direction from the center to the edge of the bubble breaker grille 155. Therefore, the width B2 can be the average width of the third exhaust hole 1555a. The thickness and number of the rib plates 1559 can be adjusted according to the size of the bubble breaker assembly 15.

The inner peripheral wall of the buckle groove 151a, the exhaust assembly 13 and the pot lid body 11 enclose a second buffer space 15b, that is, the above-mentioned preliminary buffer space, which is the space for buffering the airflow flowing out of the exhaust assembly 13 first.

[0111] In an embodiment of the present invention, the pot lid assembly 10 further includes a seal 17. The bubble breaker cover 153 is connected to the pot lid body 11. The seal 17 is installed on the outer peripheral surface of the bubble breaker cover 153 and abuts against the pot lid body 11.

[0112] In this embodiment, in order to improve the sealing performance of the pot lid assembly 10, a seal 17 is provided at the connection position between the bubble breaker cover 153 and the pot lid body 11. Specifically, the seal 17 is an O-ring or sealing cotton, etc., so as to ensure the sealing effect at the connection position between the two, prevent air leakage from this place, ensure the normal buffering and discharge of the airflow, and effectively reduce the generation of extra noise. Here, for the convenience of installing the seal 17, a sealing groove is opened on the outer peripheral surface of the bubble breaker cover 153, and the seal 17 is fixed in the sealing groove, and the opening of the sealing groove faces the connection structure of the pot lid body 11, so that the seal 17 abuts against the pot lid body 11 to achieve effective sealing. Of course, in other embodiments, the seal 17 can also be directly attached between the bubble breaker cover 153 and the pot lid body 11.

[0113] Please refer to Figure 1 and Figure 14 In addition, the present invention also provides an electric pressure cooker 100.
