[0048] First Embodiment

[0049] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a cross-sectional structural diagram of the first embodiment of the cooking device of this application. Figure 2 yes Figure 1 The enlarged schematic diagram of a partial structure shows that, in this embodiment, the cooking device 100 may include a cooking body 110 and a bubble breaker 120 disposed on the cooking body 110. The cooking body 110 forms a cooking chamber for heating food and further includes an exhaust valve core 113. The bubble breaker 120 includes a housing 121 and an exhaust valve 122. The housing 121 forms a receiving cavity, and the exhaust valve 122 is disposed within the receiving cavity. The exhaust valve core 113 connects the cooking chamber and the receiving cavity, and the exhaust valve 122 is disposed at the outlet end of the exhaust valve core 113. The receiving cavity further collects the broth overflowing from the outlet end of the exhaust valve core 113.

[0050] In the cooking device 100 provided in this embodiment, the exhaust valve 122 is installed in the receiving cavity of the bubble breaker 120, and the exhaust valve core 113 is also located in the receiving cavity of the bubble breaker 120. During the exhaust process, when the soup in the cooking cavity overflows from the exhaust valve core 113, the soup collects in the receiving cavity of the bubble breaker 120, thereby preventing the soup from contaminating the lid of the cooking device 100.

[0051] Next, the specific structure of the cooking body 110 will be described. For example... Figure 1 and Figure 3 As shown, Figure 3 yes Figure 1 The schematic diagram of the main cooking body shows that the main cooking body 110 may include a pot body 111, a pot lid 112 fastened to the pot body 111, an exhaust valve core 113 fixed to the pot lid 112, a transmission mechanism 114 disposed on the pot lid 112, and a float 115 disposed on the pot lid 112.

[0052] The pot body 111 and the pot lid 112 cooperate to form a cooking cavity for cooking food. The surface of the pot lid 112 away from the pot body 111 is the top cover. The pot lid 112 can be snapped onto the pot body 111, for example, the pot lid 112 can be rotated and snapped onto the pot body 111. The pot lid 112 can also be connected to the pot body 111 in a flip-top manner, for example, one end of the pot lid 112 can be hinged to the pot body 111. This embodiment does not limit this, and those skilled in the art can choose according to actual needs.

[0053] like Figure 2 As shown, the lid 112 may be provided with mounting grooves 1121 and handles 1122 at intervals. The mounting groove 1121 is used to mount the bubble breaker 120. The mounting groove 1121 can be an annular groove, and the bottom of the bubble breaker 120 is disposed within the mounting groove 1121. Positioning bosses 11211 may be provided at intervals on the sidewalls of the mounting groove 1121. For example, the number of positioning bosses 11211 can be four, evenly distributed along the circumference of the mounting groove 1121. However, this embodiment is not limited to this; the number of positioning bosses 11211 can be one, two, three, or even more, and those skilled in the art can select according to actual needs.

[0054] Of course, the mounting groove 1121 can also be any shape, such as a square groove or a hexagonal groove. This application does not limit this, and those skilled in the art can choose according to actual needs.

[0055] Please refer to the following: Figure 2 and Figure 3The exhaust valve core 113 is tubular and fixed to the bottom of the mounting groove 1121. During cooking, the cooking chamber needs to be kept sealed. At this time, the exhaust valve 122 seals the exhaust valve core 113's outlet end. After cooking, the transmission mechanism 114 drives the exhaust valve 122 to rise, creating an exhaust gap between the exhaust valve 122 and the exhaust valve core 113. At this time, the exhaust valve core 113 connects the cooking chamber of the cooking body 110 with the receiving chamber of the bubble breaker 120.

[0056] like Figure 1 As shown, the transmission mechanism 114 may include a button 1141, a rocker arm 1142, and a first return element 1143. The button 1141 may be located on the handle 1122 for easy user pressing. After the cooking process is complete, the user can press the button 1141. The button 1141, under the user's pressure, pushes one end of the rocker arm 1142, causing the other end of the rocker arm 1142 to tilt upwards and push the exhaust valve 122. This creates an exhaust gap between the exhaust valve 122 and the exhaust valve core 113, allowing steam in the cooking chamber to enter the accommodating cavity of the bubble breaker 120 through the exhaust gap from the outlet of the exhaust valve core 113. After the user's pressing action is released, the first return element 1143 can drive the button 1141 to reset. For example, the first return element 1143 may be a spring sleeved on the lower end of the button 1141.

[0057] The float 115 is located at the bottom of the mounting groove 1121. When pressure is generated in the cooking cavity, the steam pressure will push the float 115 upward.

[0058] Next, the specific structure of the bubble breaker 120 will be described. Please refer to [link / reference needed]. Figure 2 and Figure 4-5 , Figure 4 yes Figure 1 A schematic diagram of the exploded structure of the bubble breaker. Figure 5 yes Figure 1 Another exploded view of the bubble breaker shows that the bubble breaker 120 may include a housing 121, an exhaust valve 122 disposed within the housing 121, a seal 123 disposed on the housing 121, a push rod 124, a second return member 125 and an indicator rod 126, and an elastic member 127 for forming a tight fit between the housing 121 and the sidewall of the mounting groove 1121.

[0059] The housing 121 may include a bottom shell 1211 and a top shell 1212, which are fastened together to form a receiving cavity. In this embodiment, the top shell 1212 and the bottom shell 1211 are detachably connected, for example, they can be snap-fitted together, allowing the user to easily disassemble the top shell 1212 and the bottom shell 1211 for cleaning the receiving cavity. In some embodiments, the top shell 1212 and the bottom shell 1211 may also be non-detachable, and those skilled in the art can choose according to actual needs.

[0060] The bottom shell 1211 can be detachably connected to the pot lid 112. For example, the bottom shell 1211 and the pot lid 112 can be snap-fitted together, making it convenient for users to remove the entire bubble breaker 120 from the pot lid 112 for cleaning. Specifically, the bottom of the bottom shell 121 can be inserted into the mounting groove 1121 and fixed by the tight fit between the elastic member 127 and the side wall of the mounting groove 1121. In some embodiments, the bottom shell 1211 and the pot lid 112 can also be non-detachable. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0061] like Figure 6 As shown, Figure 6 yes Figure 5 The structural diagram of the bottom shell shows that the bottom shell 1211 may include a bottom plate 12111 adjacent to the top cover, an outer cylinder 12112 connecting the bottom plate 12111 and the top shell 1212, a limiting mechanism 12113 disposed on the bottom plate, and a guide cylinder 12114 disposed on the bottom plate 12111.

[0062] The base plate 12111 may be provided with an insertion hole 12111a for inserting the air supply and exhaust valve core 113. The accommodating cavity is located on the side of the base plate 12111 away from the face cover. The base plate 12111 and the outer cylinder 12112 may be integrally formed or assembled as two pieces.

[0063] In this embodiment, the limiting mechanism 12113 may include an annular rib 12113a surrounding the insertion hole 12111a and extending toward the top shell 1212, and a boss 12113b disposed in the area surrounded by the annular rib 12113a. The exhaust valve 122 is limited to the area surrounded by the annular rib 12113a, so that after the exhaust valve core 113 is inserted into the insertion hole 12111a, the exhaust valve 122 can cooperate with the exhaust valve core 113.

[0064] The annular rib 12113a is provided with at least two notches 12113c spaced circumferentially along the annular rib 12113a, so that the soup overflowing from the vent end of the exhaust valve core 113 can flow out through the notches 12113c, preventing the soup from accumulating in the area surrounded by the annular rib 12113a. In some embodiments, the number of notches 12113c may also be one, and this embodiment does not limit this, and those skilled in the art can choose according to actual needs.

[0065] The outer surface of the outer cylinder 12112 may be provided with a positioning groove 12112a, which can cooperate with the positioning boss 11211 on the side wall of the mounting groove 1121 to prevent misalignment of the exhaust gas installation. The positioning groove 12112a and the positioning boss 11211 can be provided in a one-to-one correspondence.

[0066] like Figure 7 As shown, Figure 7 yes Figure 5 A schematic diagram of the top shell structure shows that the top shell 1212 has a protrusion 12121 and an exhaust port 12122 arranged parallel to the protrusion 12121. Specifically, the protrusion 12121 cooperates with the annular surrounding rib 12113a to limit the exhaust valve 122. The exhaust port 12122 connects the accommodating cavity to the outside atmosphere. Further, as... Figure 2 As shown, the guide tube 12114 set on the base plate 12111 can be connected to the exhaust port 12122.

[0067] The seal 123 can be fitted into the insertion hole 12111a on the base plate 12111. For example... Figure 8 and Figure 9 As shown, Figure 8 yes Figure 5 A schematic diagram of the structure of one embodiment of the central sealing element. Figure 9 yes Figure 8 A cross-sectional structural diagram of the sealing element shows that the sealing element 123 may include a cylindrical portion 1231 forming a hollow channel, a sealing portion 1232 sealing one end of the cylindrical portion 1231, and a first flange 1233 and a second flange 1234 disposed on the outer peripheral surface of the cylindrical portion 1231.

[0068] The first flange 1233 and the second flange 1234 are spaced apart along the axial direction of the cylindrical portion 1231. The cylindrical portion 1231 is embedded in the insertion hole 12111a. The first flange 1233 and the second flange 1234 are located on both sides of the base plate 12111 and interfere with the base plate 12111 along the axial direction of the cylindrical portion 1231.

[0069] like Figure 8As shown, the sealing part 1232 can be disposed at one end of the cylindrical part 1231 near the receiving cavity and seal the hollow channel of the cylindrical part 1231. In some embodiments, the sealing part 1232 can also seal one end of the cylindrical part 1231 near the cooking cavity. This application does not limit this, and those skilled in the art can choose according to actual needs.

[0070] A cross-shaped slit 12321 may be provided on the sealing part 1232. When the bubble breaker 120 is installed on the pot lid 112, the exhaust valve core 113 is inserted into the receiving cavity of the bubble breaker 120 through the insertion hole 12111a, the cross-shaped slit 12321 is opened, and the sealing member 123 seals the gap between the exhaust valve core 113 and the insertion hole 12111a, preventing soup or gas from overflowing from the gap between the exhaust valve core 113 and the insertion hole 12111a. When the bubble breaker 120 is removed from the pot lid 112, the exhaust valve core 113 is pulled out from the insertion hole 12111a, the cross-shaped slit 12321 automatically closes, forming a seal on the insertion hole 12111a, preventing soup remaining in the receiving cavity from overflowing from the insertion hole 12111a, thus keeping the cooking body 110 clean.

[0071] In some embodiments, the slit 12321 on the sealing portion 1232 may also be arc-shaped, such as... Figure 10 As shown, Figure 10 yes Figure 5 A schematic diagram of another embodiment of the sealing element. This embodiment does not limit the specific shape of the slit 12321; those skilled in the art can choose according to actual needs.

[0072] Optionally, the maximum size of the slit 12321 is smaller than the diameter of the exhaust valve core 113 to ensure that when the exhaust valve core 113 is inserted, the seal 123 can seal the gap between the exhaust valve core 113 and the insertion hole 12111a.

[0073] Please refer to the following: Figure 2 and Figure 5 The push rod 124 can be positioned within the area surrounded by the annular rib 12113a. When the user presses the button 1141, the button 1141 pushes one end of the rocker arm 1142, causing the other end of the rocker arm 1142 to tilt upwards, thus pushing the push rod 124 upwards. The push rod 124 further pushes the exhaust valve 122 upwards, creating an exhaust gap between the exhaust valve 122 and the exhaust valve core 113, thereby venting the exhaust. After the user's pressing action is canceled, the second return element 125 can assist the push rod 124 in resetting. For example, the second return element 125 can be a spring sleeved on the lower end of the push rod 124.

[0074] like Figure 2As shown, in this embodiment, when the push rod 124 is in its natural state, that is, when it is not subjected to the thrust from the transmission mechanism 114, the upper end of the push rod 124 protrudes from the base plate 12111. To ensure the balance of the exhaust valve 122, the boss 12113b provided on the base plate 12111 can cooperate with the push rod 124 to jointly support the exhaust valve 122. In some embodiments, when the push rod 124 is in its natural state, the upper end of the push rod 124 can also be flush with the base plate 12111. In this case, the boss 12113b is not required.

[0075] Please refer to the following: Figure 2 and Figure 5 The indicator rod 126 is located inside the guide tube 12114. When the float 115 rises under the pressure inside the cooking cavity, it can push the indicator rod 126 out of the vent hole 12122 on the top shell 1212 to indicate the pressure inside the cooking cavity, so that the user can understand the cooking situation.

[0076] Please continue reading. Figure 2 and Figure 5 The elastic element 127 is disposed at the bottom of the outer cylinder 12112 of the bottom shell 1211, and is used to form a tight fit between the outer cylinder 12112 of the bottom shell 1211 and the side wall of the mounting groove 1121, thereby fixing the bottom shell 1211 in the mounting groove 1121.

[0077] Second Embodiment

[0078] Please refer to the following: Figure 11 and Figure 12 , Figure 11 This is a cross-sectional structural diagram of the second embodiment of the cooking device of this application. Figure 12 yes Figure 11 The enlarged schematic diagram of a partial structure shows that, in this embodiment, the cooking device 200 may include a cooking body 210 and a bubble breaker 220 detachably mounted on the cooking body 210. The cooking body 210 forms a cooking chamber for heating food. The bubble breaker 220 includes a housing 211, an exhaust valve core 228, and an exhaust valve 222. The housing 211 forms a receiving cavity, and the exhaust valve 222 is disposed within the receiving cavity. The exhaust valve core 228 is fixed to the housing 211 and connects the cooking chamber and the receiving cavity. The exhaust valve 222 is located at the outlet end of the exhaust valve core 228. The receiving cavity further collects the broth overflowing from the outlet end of the exhaust valve core 228.

[0079] In the cooking device 200 provided in this embodiment, the exhaust valve 222 is installed in the receiving cavity of the bubble breaker 220, and the exhaust valve core 228 is also located in the receiving cavity of the bubble breaker 220. During the exhaust process, when the soup in the cooking cavity overflows from the exhaust valve core 228, the soup collects in the receiving cavity of the bubble breaker 220, thereby preventing the soup from contaminating the lid of the cooking device 200.

[0080] Next, the specific structure of the cooking body 210 will be described. For example... Figure 11 and Figure 12 As shown, the cooking body 210 may include a pot body 211, a pot lid 212 fastened to the pot body 211, an exhaust pipe 216 disposed on the pot lid 212, an assembly cylinder 217 disposed at the end of the exhaust pipe 216 away from the cooking cavity, a sealing element 218 disposed at the end of the assembly cylinder 217 away from the cooking cavity, a transmission mechanism 214 disposed on the pot lid 212, and a float 215 disposed on the pot lid 212.

[0081] In this embodiment, the specific structure and connection relationship of the pot body 211, pot lid 212, transmission mechanism 214 and float 215 can be similar to or the same as those in the first embodiment, and will not be described again here.

[0082] An exhaust pipe 216 is disposed on the pot lid 212, and an assembly cylinder 217 is disposed at the end of the exhaust pipe 216 away from the cooking cavity. In this embodiment, the upper end face of the assembly cylinder 217 may protrude from the upper surface of the pot lid 212. In some embodiments, the upper end face of the assembly cylinder 217 may also be flush with the upper surface of the pot lid 212, and those skilled in the art can choose according to actual needs.

[0083] like Figure 13 As shown, Figure 13 yes Figure 12 A cross-sectional view of the assembly cylinder and sealing element is shown. The end of the assembly cylinder 217 furthest from the cooking cavity may have an insertion hole 2171. When the bubble breaker 220 is mounted on the lid 212, the exhaust valve core 228 is inserted into the assembly cylinder 217 through the insertion hole 2171 and mates end-to-end with the exhaust pipe 216, allowing air from the cooking cavity to pass through the exhaust pipe 216 and exit from the exhaust valve core 228. Furthermore, an annular flange 2172 may be provided on the outer peripheral wall of the end of the assembly cylinder 217 furthest from the cooking cavity.

[0084] The seal 218 can be fitted to the end of the assembly cylinder 217 furthest from the cooking cavity. For example... Figure 14 As shown, Figure 14 yes Figure 12A cross-sectional structural diagram of the sealing element is shown. The sealing element 218 includes an annular fixing part 2181 and a sealing part 2182. The annular fixing part 2181 wraps around the annular flange 2172 on the assembly cylinder 217 and forms a hollow channel. The sealing part 2182 blocks the hollow channel formed by the annular fixing part 2181.

[0085] like Figure 14 As shown, the sealing part 2182 may be provided with an opening 21821 for the exhaust valve core to pass through. In this embodiment, the opening 21821 can be circular. Of course, the opening 21821 can also be square or hexagonal, and those skilled in the art can choose according to actual needs.

[0086] Optionally, the diameter of the opening 21821 is smaller than the diameter of the exhaust valve core 228 to ensure that when the exhaust valve core 228 is inserted, the seal 218 can seal the gap between the exhaust valve core 228 and the insertion hole 2171, preventing soup or gas from overflowing from the gap between the exhaust valve core 228 and the insertion hole 2171.

[0087] In some embodiments, the sealing part 2182 may also have a cross-shaped slit. When the bubble breaker 220 is installed on the pot lid 212, the exhaust valve core 228 is inserted into the assembly cylinder 217 through the insertion hole 2171, the cross-shaped slit on the sealing part 2182 is opened, and the sealing member 218 seals the gap between the exhaust valve core 228 and the insertion hole 2171, preventing soup or gas from overflowing from the gap between the exhaust valve core 228 and the insertion hole 2171. When the bubble breaker 220 is removed from the pot lid 212, the exhaust valve core 228 is pulled out from the insertion hole 2171, the cross-shaped slit automatically closes, and the sealing member 218 seals the insertion hole 2171 of the assembly cylinder 217, preventing foreign objects from entering the cooking cavity through the insertion hole 2171. In some embodiments, the slit on the sealing part 2182 may also be arc-shaped.

[0088] Next, please continue reading. Figure 12 The specific structure of the bubble breaker 220 is described below. The bubble breaker 220 may include a housing 211, an exhaust valve 222 disposed within the housing 211, an exhaust valve core 228 disposed on the housing 211, a push rod 224, a second return member 225 and an indicator rod 226, and an elastic member 227 for forming a seal between the housing 211 and the lid 212.

[0089] In this embodiment, the specific structure and connection relationship of the housing 211, exhaust valve 222, top rod 224, indicator rod 226 and seal 218 can be similar to or the same as those in the first embodiment, and will not be described again here.

[0090] The exhaust valve core 228 is fixed to the bottom shell 2111 of the housing 211 and is arranged in a tubular shape. The air inlet end of the exhaust valve core 228 protrudes from the side of the bottom shell 2111 facing the pot lid 212, so that it can be inserted into the assembly cylinder 217 and mate end-to-end with the exhaust pipe 216. The air outlet end of the exhaust valve core 228 corresponds to the exhaust valve 222 and cooperates with it. The exhaust valve core 228 can be integrally formed with the bottom shell 2111 or assembled with the bottom shell 2111 as a two-piece assembly. This embodiment does not limit this, and those skilled in the art can choose according to actual needs.

[0091] In the first embodiment, the exhaust valve core 228 is disposed on the pot lid 212 of the cooking body 210. Since the exhaust valve core 228 needs to be inserted into the receiving cavity of the bubble breaker 220 to cooperate with the exhaust valve 222, the exhaust valve core 228 protrudes relatively large from the pot lid 212. When the bubble breaker 220 is removed, the exhaust valve core 228 may affect the appearance of the cooking body 210 and may easily scratch the user.

[0092] In this embodiment, the exhaust valve core 228 is fixed to the housing 211 of the bubble breaker 220, so that when the bubble breaker 220 is installed on the pot lid 212, the exhaust valve core 228 is connected to the exhaust pipe 216 on the pot lid 212, connecting the cooking chamber to the bubble breaker 220. This avoids the exhaust valve core 228 protruding too high from the pot lid 212, which helps to improve the appearance of the cooking body 210 and prevents the user from being scratched.

[0093] Third Embodiment

[0094] Please refer to the following: Figure 15 and Figure 16 , Figure 15 This is a cross-sectional structural diagram of the third embodiment of the cooking device of this application. Figure 16 yes Figure 15 The enlarged schematic diagram of a partial structure shows that the cooking device 300 may include a cooking body 310 and a bubble breaker 320 disposed on the cooking body 310. The cooking body 310 forms a cooking chamber for heating food and further includes an exhaust valve core 313. The bubble breaker 320 includes a housing 321 and an exhaust valve 322. The housing 321 forms a receiving cavity, and the exhaust valve 322 is disposed within the receiving cavity. The exhaust valve core 313 connects the cooking chamber and the receiving cavity, and the exhaust valve 322 is located at the exhaust outlet end of the exhaust valve core 313.

[0095] Next, the structure of the cooking body 310 will be described in detail. For example... Figure 15 As shown, the cooking body 310 may include a pot body 311, a pot lid 312 fastened to the pot body 311, an exhaust valve core 313 fixed to the pot lid 312, and a transmission mechanism 314.

[0096] The pot body 311 and the pot lid 312 cooperate to form a cooking cavity for cooking food. The surface of the pot lid 312 away from the pot body 311 is the top cover. The pot lid 312 can be snapped onto the pot body 311, for example, the pot lid 312 can be rotated and snapped onto the pot body 311. The pot lid 312 can also be connected to the pot body 311 in a flip-top manner, for example, one end of the pot lid 312 can be hinged to the pot body 311. This embodiment does not limit this, and those skilled in the art can choose according to actual needs.

[0097] like Figure 15 and Figure 16 As shown, the pot lid 312 may be provided with a mounting groove 3121, and the exhaust valve core 313 may be fixed to the bottom of the mounting groove 3121. The mounting groove 3121 is used to install the bubble breaker 320. The mounting groove 3121 may be an annular groove, and the bottom of the bubble breaker 320 is disposed within the mounting groove 3121. Of course, the mounting groove 3121 may also be any shape, such as a square groove or a hexagonal groove. This application does not limit this, and those skilled in the art can choose according to actual needs.

[0098] like Figure 15 and Figure 16 As shown, the transmission mechanism 314 may include an electromagnet 3141, a push rod 3142, a push rod 3143, and a return member 3144. The push rod 3143 may be fixed to the bottom of the mounting groove 3121, and the return member 3144 is sleeved on the lower end of the push rod 3143. The electromagnet 3141 may be disposed inside the pot body 311, and the push rod 3142 may be partially disposed inside the pot lid 312 and partially disposed inside the pot body 311. When the cooking device 300 needs to release air, the electromagnet 3141 may drive the push rod 3142 to push the push rod 3143 upward. After the air release is completed, the return member 3144 drives the push rod 3143 to return to its original position. For example, the return member 3144 may be a spring sleeved on the lower end of the push rod 3143. This embodiment does not limit this, and those skilled in the art can choose according to actual needs.

[0099] Next, the structure of the bubble breaker 320 will be described in detail. Please refer to [link / reference needed]. Figure 17 and Figure 18 , Figure 17 yes Figure 15 A cross-sectional structural diagram of the bubble breaker. Figure 18 yes Figure 15 The exploded structure diagram of the bubble breaker 320 shows that the bubble breaker 320 may include a housing 321, an exhaust valve 322 disposed in the housing 321, a first seal 323 disposed on the housing 321, a second seal 324 disposed on the housing 321, and a spacer assembly 325 disposed in the housing 321.

[0100] The housing 321 may include a bottom housing 3211 and a top housing 3212, which are fastened together to form a receiving cavity. In this embodiment, the top housing 3212 and the bottom housing 3211 are detachably connected, for example, by snap-fit ​​connection, allowing the user to easily disassemble them for cleaning the receiving cavity. In some embodiments, the top housing 3212 and the bottom housing 3211 may also be non-detachable, as those skilled in the art can choose according to actual needs.

[0101] The bottom shell 3211 can be detachably connected to the pot lid 312. For example, the bottom shell 3211 and the pot lid 312 can be snap-fitted together, making it convenient for the user to remove the entire bubble breaker 320 from the pot lid 312 for cleaning. Specifically, the bottom of the bottom shell 3211 can be inserted into the mounting groove 3121. In some embodiments, the bottom shell 3211 and the pot lid 312 can also be non-detachable. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0102] like Figure 17 As shown, the bottom shell 3211 may include a bottom plate 32111, which is disposed adjacent to the top cover, and the accommodating cavity is disposed on the side of the bottom plate 32111 away from the top cover. The bottom plate 32111 may be provided with a first insertion hole 32111a for inserting the exhaust valve core 313 and a second insertion hole 32111b for inserting the top rod 3143.

[0103] like Figure 18 As shown, the top shell 3212 is provided with a protrusion 32121 and a plurality of vent holes 32122 arranged around the protrusion 32121. The vent holes 32122 connect the accommodating cavity to the outside atmosphere. The specific number of vent holes 32122 is not limited in this embodiment; those skilled in the art can select them according to actual needs. Furthermore, as... Figure 17 As shown, a latch 32123 is also provided on the top shell 3212.

[0104] like Figure 17As shown, the exhaust valve 322 is positioned directly above the first insertion hole 32111a and the second insertion hole 32111b. The exhaust valve core 313 can be inserted into the receiving cavity of the bubble breaker 320 through the first insertion hole 32111a, cooperating with the exhaust valve 322 located within the receiving cavity. Specifically, during cooking, the cooking cavity needs to remain sealed. At this time, the exhaust valve 322 seals the exhaust valve core 313's outlet. After cooking, the electromagnet 3141 drives the push rod 3142 to push the top rod 3143 upward, lifting the exhaust valve 322, thus creating an exhaust gap between the exhaust valve 322 and the exhaust valve core 313. At this time, the exhaust valve core 313 connects the cooking cavity of the cooking body 310 with the receiving cavity of the bubble breaker 320.

[0105] The first seal 323 is used to seal the first insertion hole 32111a. Please refer to the following: Figure 19 and Figure 20 , Figure 19 yes Figure 18 A schematic diagram of the structure of the first seal in the middle. Figure 20 yes Figure 18 A cross-sectional structural schematic diagram of the first sealing element shows that the first sealing element 323 may include a cylindrical portion 3231 forming a hollow channel, a sealing portion 3232 sealing one end of the cylindrical portion 3231, and a first flange 3233 and a second flange 3234 disposed on the outer peripheral surface of the cylindrical portion 3231.

[0106] The first flange 3233 and the second flange 3234 are axially spaced from each other on the cylindrical portion 3231. The cylindrical portion 3231 is embedded in the first insertion hole 32111a. The first flange 3233 and the second flange 3234 are located on both sides of the base plate 32111 respectively, and interfere with the base plate 32111 along the axial direction of the cylindrical portion 3231.

[0107] like Figure 20 As shown, the sealing part 3232 can be disposed at one end of the cylindrical part 3231 near the receiving cavity and seal the hollow channel of the cylindrical part 3231. In some embodiments, the sealing part 3232 can also seal one end of the cylindrical part 3231 near the cooking cavity. This application does not limit this, and those skilled in the art can choose according to actual needs.

[0108] A circular opening 32321 may be provided on the sealing part 3232 for the exhaust valve core 313 to pass through. In some embodiments, the opening 32321 may also be square or hexagonal, and those skilled in the art can choose according to actual needs.

[0109] Optionally, the diameter of the opening 32321 is smaller than the diameter of the exhaust valve core 313, so as to ensure that when the exhaust valve core 313 is inserted, the first seal 323 can seal the gap between the exhaust valve core 313 and the first insertion hole 32111a, preventing gas from escaping from the gap between the exhaust valve core 313 and the first insertion hole 32111a. The sealing part 3232 may also be provided with the slit structure described above, so as to achieve automatic sealing after the exhaust valve core 313 is pulled out.

[0110] The second seal 324 is used to seal the second mortise 32111b. Please refer to the following: Figure 21 and Figure 22 , Figure 21 yes Figure 18 A schematic diagram of the structure of the second seal. Figure 22 yes Figure 18 A cross-sectional structural schematic diagram of the second sealing element shows that the second sealing element 324 may include a cylindrical portion 3241 forming a hollow channel, a sealing portion 3242 sealing one end of the cylindrical portion 3241, and a first flange 3243 and a second flange 3244 disposed on the outer peripheral surface of the cylindrical portion 3241.

[0111] The second sealing element 324 differs from the first sealing element 324 in that: the cylindrical portion 3241 has a folding structure 32411 at the end near the accommodating cavity, which gives the cylindrical portion 3241 a certain degree of extensibility. The sealing portion 3242 is located at the end of the cylindrical portion 3241 near the accommodating cavity and seals the hollow channel formed by the cylindrical portion 3241. The sealing portion 3242 may not have any openings or slits, resulting in a completely sealed state.

[0112] The push rod 3143 is inserted into the hollow channel formed by the cylindrical part 3241 from the lower end of the second seal 324. When the push rod 3143 rises, due to the extensibility of the folded structure 32411, the push rod 3143 pushes the sealing part 3242 upward, thereby lifting the exhaust valve 322, so that an exhaust gap is formed between the exhaust valve core 313 and the exhaust valve 322.

[0113] Please see Figure 23 , Figure 23 yes Figure 18An exploded view of the intermediate partition assembly 325 shows that the partition assembly 325 can be disposed within the accommodating cavity. The partition assembly 325 includes a cylindrical body 3251 and a sealing gasket 3252. The cylindrical body 3251 divides the accommodating cavity into a first cavity and a second cavity. The internal space of the cylindrical body 3251 is the first cavity, which is connected to the cooking cavity via an exhaust valve core 313. The external space of the cylindrical body 3251 is the second cavity, which is connected to the external atmosphere. The first cavity and the second cavity are connected to each other via a flow-limiting channel 32511. The flow-limiting channel 32511 is configured such that gas entering the first cavity via the exhaust valve core 313 can travel a certain distance around the central axis of the exhaust valve core 313 before being discharged into the second cavity.

[0114] The cylindrical body 3251 can cooperate with the protrusion 32121 on the top shell 3212 to limit the exhaust valve 322 disposed in the first cavity, so that the exhaust valve 322 and the exhaust valve core 313 inserted into the first cavity cooperate with each other.

[0115] The cylindrical body 3251 may include a first end face and a second end face disposed opposite to each other. In this embodiment, the first end face of the cylindrical body 3251 is fixedly connected to the bottom plate 32111 of the bottom shell 3211. The two can be integrally formed or assembled together as two pieces. When the bottom shell 3211 and the top shell 3212 are assembled together, the cylindrical body 3251 is inserted into the protrusion 32121, and its second end face abuts against the top wall of the protrusion 32121. A sealing gasket 3252 is disposed between the second end face of the cylindrical body 3251 and the top wall of the protrusion 32121.

[0116] In this embodiment, the flow-limiting channel 32511 can be disposed between the second end face of the cylindrical body 3251 and the sealing gasket 3252. Specifically, the flow-limiting channel 32511 is formed on the second end face of the cylindrical body 3251 and surrounds the central axis of the exhaust valve core 313, with an extension length not less than one-third of the circumference of the cylindrical body 3251. For example, such as Figure 23 As shown, the flow-limiting channel 32511 can surround half of the cylindrical body 3251. Gas in the first cavity enters the flow-limiting channel 32511 through the air inlet 32512, and then flows out of the flow-limiting channel 32511 through the air outlet 32513 and enters the second cavity. In some embodiments, the flow-limiting channel 32511 can also be formed on the side of the sealing gasket 3252 near the cylindrical body 3251.

[0117] In this embodiment, the gas discharged from the exhaust valve core 313 first enters the first chamber, where its volume increases and it expands; then it enters the flow-limiting channel 32511, where its volume decreases and it is compressed; subsequently, it flows into the second chamber through the flow-limiting channel 32511, and then enters the atmosphere through the exhaust port 32122 on the top shell 3212, where its volume increases and it expands. After undergoing the expansion-compression-expansion process, the gas's energy decreases, its flow rate decreases, and thus the exhaust noise is reduced. At the same time, the flow-limiting channel 32511 can also control the gas flow rate, reducing the airflow and preventing soup from overflowing.

[0118] Furthermore, in this embodiment, the flow-limiting channel 32511 is configured such that the gas entering the first cavity through the exhaust valve core 313 can travel a certain distance around the central axis of the exhaust valve core 313 before being discharged into the second cavity. This is beneficial for increasing the extension length of the flow-limiting channel 32511, further reducing the gas flow rate, and reducing exhaust noise.

[0119] In some embodiments, the flow restriction channel 32511 may also be disposed between the top wall of the protrusion 32121 and the sealing gasket 3252. For example, the flow restriction channel 32511 may be disposed on the top wall of the protrusion 32121 or on the side of the sealing gasket 3252 away from the cylindrical body 3251. Those skilled in the art can choose according to actual needs.

[0120] In some embodiments, the first end face of the cylindrical body 3251 is fixedly connected to the top shell 3212, and when the bottom shell 3211 and the top shell 3212 are assembled together, the second end face of the cylindrical body 3251 abuts against the bottom shell 3211. A sealing gasket 3252 is disposed between the second end face of the cylindrical body 3251 and the bottom shell 3211. In this case, the flow-limiting channel 32511 can be disposed between the second end face of the cylindrical body 3251 and the sealing gasket 3252, or between the bottom shell 3211 and the sealing gasket 3252. This application does not limit this, and those skilled in the art can choose according to actual needs.

[0121] In some embodiments, the spacer assembly 325 may not include the sealing gasket 3252, and the flow-limiting channel 32511 may be directly disposed between the cylindrical body 3251 and the top shell 3212 or between the cylindrical body 3251 and the bottom shell 3211. Those skilled in the art can choose according to actual needs. The sealing gasket 3252 helps to restrict the flow direction of gas and ensure that gas flows along the flow-limiting channel 32511.

[0122] Optionally, in the direction perpendicular to the airflow direction defined by the flow-limiting channel 32511, the cross-sectional area of ​​the flow-limiting channel 32511 is between 1 and 10 square millimeters. For example, the cross-sectional area of ​​the flow-limiting channel 32511 can be 1 square millimeter, 3 square millimeters, 4 square millimeters, 5 square millimeters, 6 square millimeters, 8 square millimeters, or 10 square millimeters.

[0123] The outer side of the cylindrical body 3251 may also be provided with a snap-fit ​​32514, which can cooperate with the snap-fit ​​32123 on the top shell 3212 to form a snap-fit ​​structure so that the bottom shell 3211 and the top shell 3212 can be connected to each other.

[0124] Fourth embodiment

[0125] Please refer to the following: Figure 24 and Figure 25 , Figure 24 This is a cross-sectional structural diagram of the fourth embodiment of the cooking device of this application. Figure 25 yes Figure 24 The enlarged schematic diagram of a partial structure shows that the cooking device 400 may include a cooking body 410 and a bubble breaker 420 disposed on the cooking body 410. The cooking body 410 forms a cooking chamber for heating food and further includes an exhaust valve core 413. The bubble breaker 420 includes a housing 421 and an exhaust valve 422. The housing 421 forms a receiving cavity, and the exhaust valve 422 is disposed within the receiving cavity. The exhaust valve core 413 connects the cooking chamber and the receiving cavity, and the exhaust valve 422 is located at the exhaust outlet end of the exhaust valve core 413.

[0126] Next, the structure of the cooking body 410 will be described in detail. For example... Figure 24 As shown, the cooking body 410 may include a pot body 411, a pot lid 412 fastened to the pot body 411, an exhaust valve core 413 fixed to the pot lid 412, and a transmission mechanism 414.

[0127] The specific structure and connection relationship of the pot body 411, pot lid 412, exhaust valve core 413 and transmission mechanism 414 can be the same as or similar to those of the third embodiment, and will not be described in detail here.

[0128] Next, the structure of the bubble deflator 420 will be described in detail. Please refer to [link / reference]. Figure 26 , Figure 26 yes Figure 24 The exploded structure diagram of the bubble breaker shows that the bubble breaker 420 may include a housing 421, an exhaust valve 422 disposed in the housing 421, a first seal 423 disposed on the housing 421, a second seal 424 disposed on the housing 421, and a spacer assembly 425 disposed in the housing 421.

[0129] The housing 421 may include a bottom housing 4211 and a top housing 4212. For example... Figure 26 As shown, the difference between the bottom shell 4211 and the third embodiment is that the bottom shell 4211 has a fastening position 42112 on its outer periphery. The top shell 4212 has a plurality of vent holes 42122, and the outer periphery of the top shell 4212 also has fastening positions 42123. The vent holes 42122 connect the accommodating cavity to the outside atmosphere. The specific number of vent holes 42122 is not limited in this embodiment; those skilled in the art can select them according to actual needs.

[0130] The snap-fit ​​42123 on the top shell 4212 can cooperate with the snap-fit ​​42112 on the bottom shell to form a snap-fit ​​structure, so that the bottom shell 4211 and the top shell 4212 are connected to each other. Other structures of the bottom shell 4211 and the top shell 4212 can be the same as or similar to those in the third embodiment, and will not be described in detail here.

[0131] The specific structures of the exhaust valve 422, the first seal 423, and the second seal 424 can be the same as or similar to those in the third embodiment, and will not be described in detail here.

[0132] Please refer to the following: Figure 26 and Figure 27 , Figure 27 yes Figure 26 A schematic diagram of the structure of the first cylindrical body is shown, in which a spacer assembly 425 can be disposed within the accommodating cavity. The spacer assembly 425 includes a cylindrical body 4251 and a sealing gasket 4252. The cylindrical body 4251 divides the accommodating cavity into a first cavity and a second cavity. The internal space of the cylindrical body 4251 is the first cavity, which is connected to the cooking cavity through an exhaust valve core 413. The external space of the cylindrical body 4251 is the second cavity, which is connected to the external atmosphere. The first cavity and the second cavity can be connected to each other through a flow-limiting channel 42513. The flow-limiting channel 42513 is configured such that gas entering the first cavity through the exhaust valve core 413 can travel a certain distance around the central axis of the exhaust valve core 413 before being discharged into the second cavity.

[0133] A cylindrical body 4251 surrounds the exhaust valve 422 and can limit the movement of the exhaust valve 422. The cylindrical body 4251 may include a first cylindrical body 42511 and a second cylindrical body 42512. The first cylindrical body 42511 is disposed on the bottom shell 4211, and the second cylindrical body 42512 is disposed on the top shell 4212. The first cylindrical body 42511 can be integrally formed with the bottom shell 4211, or it can be assembled with the bottom shell 4211 as a two-piece assembly. The second cylindrical body 42512 can be integrally formed with the top shell 4212, or it can be assembled with the top shell 4212 as a two-piece assembly (in this embodiment, the second cylindrical body 42512 and the protrusion 32121 in the third embodiment can be the same component).

[0134] When the top shell 4212 and the bottom shell 4211 are engaged, the first cylindrical body 42511 is inserted into the second cylindrical body 42512 along the axial direction of the second cylindrical body 42512. A sealing gasket 4252 may be disposed between the first cylindrical body 42511 and the second cylindrical body 42512.

[0135] In this embodiment, the flow-limiting channel 42513 can be disposed between the outer peripheral surface of the first cylindrical body 42511 and the sealing gasket 4252. Specifically, the flow-limiting channel 42513 can be formed on the outer peripheral surface of the first cylindrical body 42511, and extends spirally around the central axis of the exhaust valve core 413, with an extension length not less than one-third of the circumference of the first cylindrical body 42511. For example, such as Figure 27 As shown, the flow-limiting channel 42513 can surround the first cylindrical body 42511. The gas in the first cavity enters the flow-limiting channel 42513 through the air inlet 42514, and then flows out of the flow-limiting channel 42513 through the air outlet 42515 and enters the second cavity. In some embodiments, the flow-limiting channel 42513 can also be formed on the inner circumferential surface of the sealing gasket 4252.

[0136] In this embodiment, the gas discharged from the exhaust valve core 413 first enters the first chamber, where its volume increases and it expands; then it enters the flow-limiting channel 42513, where its volume decreases and it is compressed; subsequently, it flows into the second chamber through the flow-limiting channel 42513, and then enters the atmosphere through the exhaust port 42122 on the top shell 4212, where its volume increases and it expands. After undergoing the expansion-compression-expansion process, the gas's energy decreases, its flow rate decreases, and thus the exhaust noise is reduced. At the same time, the flow-limiting channel 42513 can also control the gas flow rate, reducing the airflow and preventing soup from overflowing.

[0137] Furthermore, in this embodiment, the flow-limiting channel 42513 is configured such that the gas entering the first cavity through the exhaust valve core 413 can travel a certain distance around the central axis of the exhaust valve core 413 before being discharged into the second cavity. This is beneficial for increasing the extension length of the flow-limiting channel 42513, further reducing the gas flow rate, and reducing exhaust noise.

[0138] In some embodiments, the flow-limiting channel 42513 may be disposed between the inner circumferential surface of the second cylindrical body 42512 and the sealing gasket 4252. For example, the flow-limiting channel 42513 may be formed on the inner circumferential surface of the second cylindrical body 42512 or on the outer circumferential surface of the sealing gasket 4252, and those skilled in the art may choose according to actual needs.

[0139] In some embodiments, a first cylindrical body 42511 is disposed on a top shell 4212, and a second cylindrical body 42512 is disposed on a bottom shell 4211. When the top shell 4212 and the bottom shell 4211 are engaged with each other, the first cylindrical body 42511 is inserted into the second cylindrical body 42512 along the axial direction of the second cylindrical body 42512.

[0140] In some embodiments, the spacer assembly 425 may not include the sealing gasket 4252, and the flow-limiting channel 42513 may be directly disposed between the first cylindrical body 42511 and the second cylindrical body 42512. Those skilled in the art can choose according to the actual situation. The arrangement of the sealing gasket 4252 helps to restrict the flow direction of gas and ensure that the gas flows along the flow-limiting channel 42513.

[0141] Optionally, in the direction perpendicular to the airflow direction defined by the flow-limiting channel 42513, the cross-sectional area of ​​the flow-limiting channel 42513 is between 1 and 10 square millimeters. For example, the cross-sectional area of ​​the flow-limiting channel 42513 can be 1 square millimeter, 3 square millimeters, 4 square millimeters, 5 square millimeters, 6 square millimeters, 8 square millimeters, or 10 square millimeters.

[0142] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
