A cooking appliance and an emulsifying device

Abstract

This application provides a cooking appliance and an emulsifying device, belonging to the field of cooking technology. The cooking appliance has a first cavity, a second cavity, and a jet orifice for emulsifying soup through jets. The jet orifice connects the first cavity and the second cavity so that the soup in the first cavity can flow to the second cavity through the jet orifice. In this application embodiment, the soup enters the smaller jet orifice from the larger first cavity. Due to the reduced space, the fat and protein in the soup are compressed and collided, which is conducive to the rapid combination of fat and protein. On the other hand, the soup in the first cavity flows through the jet orifice, creating a high-speed jet phenomenon. The fat and protein in the soup flowing rapidly into the jet orifice collide and impact with each other, which can reduce the particle size of fat and protein. The rapid collision and impact and the smaller particle size are conducive to the rapid combination of the lipophilic groups of fat and protein, thereby increasing the viscosity of the soup in a shorter time.

Due to the reduced space, the fat and protein in the soup are squeezed and collided, which is conducive to the rapid combination of fat and protein. On the other hand, the soup in the first cavity flows through the jet hole, causing the soup to generate a relatively high-speed jet phenomenon. The fat and protein in the soup flowing rapidly into the jet hole collide and impact each other, which can reduce the particle size of fat and protein. The relatively rapid collision and impact and the smaller particle size are conducive to the rapid combination of the lipophilic groups of fat and protein. The protein with fat combined dissolves in water through the hydrophilic groups, thereby forming an oil-water emulsion state more quickly, so that the soup presents a better emulsification effect and increases the thickness of the soup in a shorter time.

Detailed Implementation

[0040] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0041] In the description of the embodiments in this application, "upper," "lower," "top," "bottom," orientation, or positional relationship are based on the appendix. Figure 1 The orientations or positional relationships shown are for illustrative purposes only and do not imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. For example, please refer to [link to relevant documentation]. Figure 1 The up and down directions are Figure 1The direction indicated by the middle arrow R1.

[0042] In related technologies, soup is simmered in a cooking appliance without any emulsification device. The soup is thickened by continuous boiling, but this requires a long time to achieve a milky-white consistency. Research has found that the emulsification and thickness of a soup are related to the state of fat, protein, and water. During cooking, meat dissolves in fat and protein. Fat, being less dense, floats on top, resulting in a thinner, less concentrated broth than desired. Proteins, however, have both hydrophilic and lipophilic groups. Fat can bind to the lipophilic groups of proteins, while the fat-bound proteins dissolve more readily in water through their hydrophilic groups. This allows the fat-bound proteins to disperse more evenly, creating an emulsified oil-water mixture, thus increasing the soup's thickness. The reason why broth can form a nearly milky white thick soup after prolonged boiling is because fat gradually combines with protein during the long boiling process. However, the rate of fat-protein combination is relatively slow during pure boiling, resulting in a lower degree and slower emulsification. Factors such as the compression and collision of fat and protein particles, as well as the particle size of fat and protein, have a significant impact on the rate of binding of the lipophilic groups of fat and protein.

[0043] Therefore, this application provides a cooking appliance; please refer to the embodiments provided. Figure 1 , Figures 3-7 , Figure 9 and Figure 10 ,as well as Figures 13-19The cooking utensil has a first cavity 101, a second cavity 102 and a jet hole 103 for emulsifying the soup by jetting. The jet hole 103 connects the first cavity 101 and the second cavity 102 so that the soup in the first cavity 101 can flow to the second cavity 102 through the jet hole 103. With this structural form, on the one hand, the soup enters the smaller jet hole 103 from the larger first cavity 101. The fat and protein in the soup are squeezed and collided due to the smaller space, which is conducive to the rapid combination of fat and protein. On the other hand, the soup in the first cavity 101 flows through the jet hole 103, which causes the soup to produce a relatively high-speed jet phenomenon. The fat and protein in the soup flowing rapidly into the jet hole 103 collide and impact each other, which can reduce the particle size of fat and protein. The relatively rapid collision and impact and the smaller particle size are conducive to the rapid combination of the lipophilic groups of fat and protein. The protein with fat combined dissolves in water through the hydrophilic groups, thereby forming an oil-water emulsion state more quickly, so that the soup presents a better emulsification effect and increases the thickness of the soup in a shorter time.

[0044] Understandably, the liquid flows from the first chamber 101 through the jet hole 103 to the second chamber 102, which receives the liquid flowing out of the jet hole. The opening of the jet hole 103 facing the first chamber 101 is the inlet of the jet hole 103, and the opening of the jet hole 103 facing the second chamber 102 is the outlet of the jet hole 103. Liquid entering the second chamber 102 can flow back to the first chamber 101 through the jet hole 103.

[0045] For example, the food can be meat, which releases fat and protein during cooking.

[0046] For example, food may be placed in the first cavity 101 and / or the second cavity 102.

[0047] In one embodiment, the soup in the first chamber 101 is heated to boiling and generates steam, which increases the pressure in the first chamber 101. The greater pressure forces the soup in the first chamber 101 into the jet hole 103 for emulsification, and then flows from the jet hole 103 to the second chamber 102.

[0048] In one embodiment, please refer to Figure 1 , Figures 3-7 , Figure 9 and Figure 10 ,as well as Figures 13-19 The cooking appliance includes a cooking body 1 and an emulsifying device 2, which is located inside the cooking body 1. The emulsifying device 2 is used to emulsify the soup.

[0049] There are multiple ways to arrange the first cavity 101 and the second cavity 102.

[0050] In one embodiment, please refer to Figure 1 , Figures 3-7 , Figure 9 and Figure 10 ,as well as Figures 13-18 The emulsifying device 2 and the cooking body 1 are arranged to form a first cavity 101. With this structure, the emulsifying device 2 plays a certain role in separating the first cavity 101 and the second cavity 102. When the soup in the first cavity 101 is boiling, a large pressure difference can be generated between the first cavity 101 and the second cavity 102, so that the soup in the first cavity 101 can flow smoothly through the jet hole 103 to the second cavity 102.

[0051] In one embodiment, please refer to Figure 19 The first cavity 101 can be formed in the emulsifying device 2.

[0052] In one embodiment, please refer to Figure 1 , Figures 3-7 , Figure 9 and Figure 10 ,as well as Figures 13-19 The emulsifying device 2 and the cooking body 1 are arranged to form a second cavity 102. With this structure, the emulsifying device 2 and the cooking body 1 are used to jointly enclose the second cavity 102, making the space of the second cavity 102 larger, reducing the resistance to the flow from the jet hole 103 to the second cavity 102, and providing sufficient space in the second cavity 102 to accommodate the soup flowing out from the jet hole 103.

[0053] In one embodiment, the second cavity 102 may be formed in the emulsifying device 2.

[0054] In one embodiment, please refer to Figure 1 , Figures 3-7 , Figure 9 and Figure 10 ,as well as Figures 13-18 The emulsifying device 2 and the cooking body 1 are arranged to form a first cavity 101 and a second cavity 102.

[0055] In one embodiment, please refer to Figure 10 and Figure 11 The emulsifying device 2 and the cooking body 1 are arranged to form a jet hole 103, and / or, please refer to Figures 1-9 ,as well as Figures 12-19 The emulsifying device 2 has jet holes 103. With this structure, the position of the jet holes 103 has little impact on the cooking body 1, which can reduce the processing difficulty of the cooking body 1.

[0056] In one embodiment, the emulsifying device 2 and the cooking body 1 are arranged to form a first cavity 101 and a second cavity 102, and a jet hole 103 connecting the first cavity 101 and the second cavity 102 is formed in the cooking body 1.

[0057] In one embodiment, please refer to Figure 10 and Figure 11 The emulsifying device 2 has protrusions 21 extending from the side of the emulsifying device 2 facing the cooking body 1. Multiple protrusions 21 are arranged circumferentially around the emulsifying device 2. The jet orifice 103 formed by the emulsifying device 2 and the cooking body 1 is located between two adjacent protrusions 21. In this structural configuration, the emulsifying device 2 and the cooking body 1 form the jet orifice 103, which is separated by the protrusions 21 facing the cooking body 1. The space between two adjacent protrusions 21 formed by the emulsifying device 2 and the cooking body 1 allows the broth to be jetted.

[0058] In one embodiment, please refer to Figure 10 and Figure 11 The protrusion 21 is tooth-shaped.

[0059] In one embodiment, please refer to Figure 10 and Figure 11 From one end of the protrusion 21 toward the center line of the emulsifying device 2 to the other end of the protrusion 21 away from the center line of the emulsifying device 2, the span of the protrusion 21 gradually decreases along the circumference of the emulsifying device 2. With this structural form, the further the protrusion 21 is from the center line of the emulsifying device 2, the smaller the span of the protrusion 21 along the circumference of the emulsifying device 2, and the larger the gap between two adjacent protrusions 21 along the circumference of the emulsifying device 2. The protrusion 21 is roughly sharp and serrated, making the processing of the protrusion 21 of the emulsifying device 2 relatively convenient.

[0060] In one embodiment, the span of the protrusion 21 along the circumference of the emulsifying device 2 can remain constant, with the end of the protrusion 21 pointing toward the center line of the emulsifying device 2 and the end of the protrusion 21 pointing away from the center line of the emulsifying device 2.

[0061] In one embodiment, please refer to Figure 1 , Figures 3-7 , Figure 9 , Figure 12 as well as Figure 18The emulsifying device 2 includes a solid boss 22 and a separator 23. The separator 23 and the solid boss 22 are connected. The solid boss 22 protrudes from the separator 22 along the axial direction of the jet hole 103. The separator 23, the solid boss 22, and the cooking body 1 enclose a first cavity 101 and / or a second cavity 102. The jet hole 103 passes through the solid boss 22, and / or the solid boss 22 and the cooking body 1 enclose a jet hole 103. With this structural form, whether the jet hole 103 penetrates the solid boss 22 or the solid boss 22 and the cooking body 1 form a jet hole 103, the length of the jet hole 103 is related to the solid boss 22 to a certain extent. Since the solid boss 22 protrudes from the separator 23 along the axial direction of the jet hole 103, the length of the jet hole 103 can be extended as much as possible. This is beneficial for the fat and protein in the soup flowing rapidly in the jet hole 103 to fully collide and impact in the longer jet hole 103, thereby reducing the particle size of fat and protein and allowing the lipophilic groups of fat and protein to combine more quickly.

[0062] In one embodiment, please refer to Figure 5 The solid boss 22 protrudes from the side of the separator 23 facing the first cavity 101.

[0063] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 4 , Figures 7-9 , Figure 12 as well as Figure 18 The solid boss 22 protrudes from the side of the separator 23 facing the second cavity 102.

[0064] In one embodiment, please refer to Figure 6 Solid boss 22 penetrates separator 23.

[0065] In one embodiment, please refer to Figure 4 The jet orifice 103 penetrates the solid boss 22. The jet orifice 103 is a straight hole, and its extending direction intersects the protruding direction of the solid boss 22. This increases the resistance to the flow of the soup through the jet orifice 103, which is beneficial for the impact and collision of fats and proteins. For an example, please refer to... Figure 4 The solid boss 22 protrudes upward from the separator 23, and the jet hole 103 is a straight hole. The axial direction of the jet hole 103 is arranged intersecting the vertical direction.

[0066] In one embodiment, please refer to Figure 12The solid boss 22 also includes a main platform 221 and an oil separator ring 222 connected to each other. The jet hole 103 passes through the main platform 221, and the oil separator ring 222 surrounds the main platform 221. The separator 23 forms an oil filter platform 231 protruding towards the main platform 221. The oil filter platform 231 is supported below the main platform 221 and has a liquid passage hole 2311. The liquid passage hole 2311 is arranged circumferentially along the main platform 221. The oil separator ring 222 covers the oil filter platform 231. The oil separator ring 222 and the separator The components 23 are arranged at intervals. The first cavity 101 includes a main cavity 104 and an oil filter cavity 105. The separator 23, the main platform 221, the oil separator ring 222 and the cooking body 1 are arranged to form the main cavity 104 and / or the second cavity 102. The oil separator ring 222, the main platform 221 and the oil filter platform 231 are arranged to form the oil filter cavity 105. The oil filter cavity 105 is located at the inlet end of the jet hole 103. The liquid passage hole 2311 connects the oil filter cavity 105 and the main cavity 104. The jet hole 103 connects the oil filter cavity 105 and the second cavity 102.

[0067] In this embodiment, the liquid in the main cavity 104 can flow sequentially through the liquid hole 2311, the oil filter cavity 105, and the jet hole 103 to the second cavity 102, causing the soup to undergo jet emulsification as it flows through the jet hole 103. When the soup stops boiling or the boiling level is low, the soup that has undergone jet emulsification through the jet hole 103 and enters the second cavity 102 can flow back to the oil filter cavity 105 through the gap between the oil separator ring 222 and the separator 23, and then flow from the oil filter cavity 105 to the first cavity 101 through the liquid hole 2311. Since fat is lighter, it can float on top of the soup, and the other parts of the soup are filtered through the oil filter. The liquid flows through the orifice and the liquid passage 2311 into the first chamber 101, causing the liquid level in the second chamber 102 to drop. When the liquid level drops to a point where the opening formed by the oil separator ring 222 and the separator 23, which connects the oil filter chamber 105 and the second chamber 102, is at least partially exposed above the liquid surface, the liquid can no longer flow through the oil filter chamber 105 and the liquid passage 2311 into the first chamber 101 via siphon action. The liquid remaining in the second chamber 102 is mainly the fat floating on top of the liquid, thus filtering out excess fat from the emulsified liquid in the second chamber 102. This method can both emulsify the liquid and filter out fat from the emulsified liquid.

[0068] In one embodiment, the emulsifying device 2 may not have a solid boss 22, and the separator 23 of the emulsifying device 2 may be a thin-walled member.

[0069] In one embodiment, please refer to Figures 1-9The cooking appliance has a return hole 106 that connects the first cavity 101 and the second cavity 102, allowing the liquid in the second cavity 102 to flow back to the first cavity 101 through the return hole 106. The return hole 106 is configured such that the sum of the minimum flow cross-sectional areas of all return holes 106 is greater than the sum of the minimum flow cross-sectional areas of all jet holes 103, and / or, the diameter of the return hole 106 is greater than the diameter of the jet holes 103. This structural configuration, with its larger diameter and / or larger sum of areas of the return holes 106, reduces the resistance to the liquid flowing through the return hole 106, facilitating a smoother and faster return of the liquid to the first cavity 101.

[0070] Understandably, the location of the reflux hole 106 is not limited.

[0071] In one embodiment, please refer to Figure 9 The emulsifying device 2 and the cooking body 1 are arranged to form a reflux hole 106.

[0072] In one embodiment, please refer to Figures 1 to 8 The emulsifying device 2 has a reflux hole 106.

[0073] In one embodiment, please refer to Figure 1 , Figures 3-7 , Figure 9 and Figure 10 ,as well as Figures 14-18 The first cavity 101 is located at least partially below the second cavity 102.

[0074] In this embodiment, the soup in the upper second cavity 102 can flow back to the first cavity 101 relatively naturally under the action of gravity, without the need to provide additional power for the backflow of the soup.

[0075] In one embodiment, please refer to Figure 3 The reflux hole 106 is located below the jet hole 103. With this structure, because the reflux hole 106 is located at a lower position, when the soup enters the second chamber 102 from the jet hole 103, the soup in the second chamber 102 will gather towards the lower reflux hole 106, which is conducive to the reflux of the soup in the second chamber 102 through the reflux hole 106.

[0076] In one embodiment, please refer to Figure 7 When the emulsifying device 2 has a reflux hole 106 located on the bottom wall of the emulsifying device 2, and a jet hole 103 located on the side wall of the emulsifying device 2, in this structural configuration, the liquid in the first chamber 101 flows through the jet hole 103, which is located higher on the side wall, into the second chamber 102. The liquid in the second chamber 102 gathers towards the reflux hole 106, which is located lower on the bottom wall, which is beneficial for the reflux of the liquid in the second chamber 102.

[0077] In one embodiment, please refer to Figure 9 When the emulsifying device 2 and the cooking body 1 are arranged to form a reflux hole 106, the reflux hole 106 is arranged circumferentially along the emulsifying device 2. With this structure, the gap between the emulsifying device 2 and the cooking body 1 is used as the reflux hole 106, eliminating the need for additional holes on the emulsifying device 2 or the cooking body 1, thus simplifying the structure of the emulsifying device 2 or the cooking body 1.

[0078] In one embodiment, please refer to Figure 13 The cooking body 1 includes a main body and a liquid level regulator. An emulsifying device 2 is located within the main body, and the emulsifying device 2 and the main body enclose a first cavity 101 and / or a second cavity 102. The liquid level regulator is installed on the main body and is capable of adjusting the liquid level in the first cavity 101 and / or the second cavity 102 to create a liquid level difference between the first cavity 101 and the second cavity 102.

[0079] In this embodiment, the liquid level regulator installed on the main body can adjust the liquid level of the first chamber 101 and / or the second chamber 102. Under the action of the liquid level regulator, a liquid level difference is generated between the first chamber 101 and the second chamber 102. The different liquid level differences between the first chamber 101 and the second chamber 102 cause a pressure difference between the first chamber 101 and the second chamber 102. Under the action of the pressure difference generated by the liquid level difference, the soup in the first chamber 101 flows to the second chamber 102 through the jet hole 103.

[0080] For example, please refer to Figure 13 The liquid level regulator can be used to heat the liquid in the first chamber 101 but not the second chamber 102, or the power of the liquid level regulator in heating the liquid in the first chamber 101 is greater than the power in heating the second chamber 102. The liquid in the first chamber 101 expands due to heating, causing the liquid level in the first chamber 101 to rise, creating a liquid level difference between the first chamber 101 and the second chamber 102. Under the pressure difference generated by the liquid level difference between the first chamber 101 and the second chamber 102, the liquid in the first chamber 101 flows through the jet hole 103 to the second chamber 102.

[0081] For example, the liquid level regulator can be used to pump the liquid in the second chamber 102 or external liquid to the first chamber 101 to raise the liquid level in the first chamber 101, thereby creating a liquid level difference between the first chamber 101 and the second chamber 102.

[0082] For example, please refer to Figure 13 The first cavity 101 is located on one side of the second cavity 102 along a preset direction, which is arranged intersecting the vertical direction. The angle between the surface where the inlet of the jet hole 103 is located and the horizontal plane is greater than a preset angle, which is 30° to 45°.

[0083] In one embodiment, please refer to Figure 1 , Figures 3-7, Figure 9 and Figure 10 ,as well as Figures 14-18 The emulsifying device 2 and the cooking body 1 are arranged to form a first cavity 101. The second cavity 102 is located above the first cavity 101. The soup in the first cavity 101 boils and generates steam, which increases the pressure in the first cavity 101. The greater pressure in the first cavity 101 forces the soup in the first cavity 101 into the jet hole 103 and flows through the jet hole 103 to the second cavity 102.

[0084] In one embodiment, please refer to Figure 15 and Figure 16 The emulsifying device 2 and the cooking body 1 are arranged to form a first cavity 101 and a second cavity 102. The cooking utensil also includes a connector and a shield 3 located in the first cavity 101. The shield 3 is arranged at intervals with the emulsifying device 2. The connector is connected to the shield 3 and the emulsifying device 2 respectively. The space enclosed by the shield 3 and the emulsifying device 2 is connected to the second cavity 102. The soup in the second cavity 102 can flow through the space enclosed by the shield 3 and the emulsifying device 2 to the side of the shield 3 away from the emulsifying device 2. In this structural configuration, the space enclosed by the shielding member 3 and the emulsifying device 2 is connected to the second cavity 102. The liquid flowing into the second cavity 102 through the jet hole 103 can flow into the space enclosed by the shielding member 3 and the emulsifying device 2. Because the shielding member 3 and the emulsifying device 2 are arranged at intervals, the liquid flowing into the space enclosed by the shielding member 3 and the emulsifying device 2 can flow back to the first cavity 101 through the gap between them. Due to the presence of the shielding member 3, the space enclosed by the shielding member 3 and the emulsifying device 2 is connected... The space and the hole of the second cavity 102 are blocked by the shielding member 3. The soup will not flow from the space enclosed by the shielding member 3 and the emulsifying device 2 and the hole of the second cavity 102 to the second cavity 102. The soup will enter the second cavity 102 as much as possible through the jet hole 103 that is not blocked by the shielding member 3 so that the soup is better emulsified. The space enclosed by the shielding member 3 and the emulsifying device 2 and the hole of the second cavity 102 can be set to be larger so that the soup in the second cavity 102 can flow back to the first cavity 101 better.

[0085] In one embodiment, please refer to Figure 15 and Figure 16 The shielding member 3 has a downwardly recessed groove 31.

[0086] In one embodiment, please refer to Figure 16 The emulsifying device 2 is partially located within the groove 31, and the shielding member 3, which is spaced apart from the emulsifying device 2, forms a siphon channel with the emulsifying device 2. During the reflux of the soup, the fat floating on top of the soup can be retained in the groove 31 of the shielding member 3, achieving the effect of filtering oil.

[0087] In one embodiment, the cooking appliance may not include the shield 3.

[0088] In one embodiment, please refer to Figure 18 The number of jet holes 103 is at least one layer. The surface where the inlet of each jet hole 103 is located is the target surface, with a preset included angle of 30° to 45°. The angle between the tangent plane of the target surface corresponding to the inlet position of at least one jet hole 103 and the horizontal plane is not greater than the preset included angle. The cooking appliance also includes a lifting device 4 connected to the cooking body 1, which is used to drive the emulsifying device 2 to rise and fall. With this structure, the angle between the tangent plane of the target surface corresponding to the inlet position of at least one jet hole 103 and the horizontal plane is not greater than the preset included angle. The angle between the tangent plane of the target surface at the inlet position of the jet hole 103 and the vertical plane is larger. The lifting device 4 drives the emulsifying device 2 to rise and fall, so that the soup in the first chamber 101 can generate a large extrusion force at the inlet position of the jet hole 103, forcing the soup in the first chamber 101 into the jet hole 103.

[0089] It is understandable that as the emulsifying device 2 rises or falls, the inlet of the jet orifice 103, the first chamber 101, and the second chamber 102 may change. For example, the inlet of the jet orifice 103 is the opening of the jet orifice 103 facing the first chamber 101. When the emulsifying device 2 falls, the second chamber 102 is above the first chamber 101. When the emulsifying device 2 rises, the first chamber 101 is above the second chamber 102.

[0090] It should be noted that a tangent plane is a plane that is tangent to a curved surface. A plane is a special type of curved surface, and the tangent plane to a given plane is the plane itself.

[0091] In one embodiment, the lifting device 4 can be a pneumatic cylinder or a hydraulic cylinder, which drives the emulsifying device 2 to rise and fall by extending or retracting the pneumatic cylinder or hydraulic cylinder.

[0092] In one embodiment, the lifting device 4 can be a threaded transmission mechanism driven by a motor.

[0093] Understandably, the jet orifice 103 can be set in layers.

[0094] For example, the number of layers of the jet hole 103 can be at least one.

[0095] It should be noted that "at least one layer" refers to a number of layers including one or more layers.

[0096] For example, please refer to Figure 1 , Figures 3-7 , Figure 9 , Figure 10 , Figure 12 , Figure 13 , Figure 15 , Figure 16 , Figure 18 and Figure 19 The jet hole 103 has one layer.

[0097] For example, the jet orifice 103 may have at least two layers.

[0098] When there are multiple layers of jet holes 103, the soup flows through the jet holes 103 layer by layer for emulsification. For example, when there are at least two layers of jet holes 103, the soup first flows through one layer of jet holes 103 for emulsification, and the soup emulsified by one layer of jet holes 103 can flow through another layer of jet holes 103 for further emulsification.

[0099] For example, please refer to Figure 14 and Figure 17 The jet orifice 103 has two layers.

[0100] In one embodiment, please refer to Figure 19 The emulsifying device 2 and the cooking body 1 form a second cavity 102. A first cavity 101 and a jet orifice 103 are formed in the emulsifying device 2. The cooking appliance also includes a liquid transfer pump 5. The input end of the liquid transfer pump 5 is connected to the second cavity 102, and the output end of the liquid transfer pump 5 is connected to the first cavity 101 to pump the liquid in the second cavity 102 to the first cavity 101. With this structure, food is placed in the second cavity 102 for cooking. The liquid in the second cavity 102 is pumped to the first cavity 101 of the emulsifying device 2 by the liquid transfer pump 5. Under the pumping pressure of the liquid transfer pump 5, the liquid in the first cavity 101 is forced into the jet orifice 103 of the emulsifying device 2 for emulsification. The emulsified liquid after passing through the jet orifice 103 flows back to the second cavity 102. By circulating the liquid to the jet orifice 103 through the liquid transfer pump 5, the fat and protein in the liquid can continuously collide and impact, thereby quickly achieving emulsification.

[0101] In one embodiment, please refer to Figure 14 and Figure 17 The cooking utensil has a concentrating cavity 107, and at least two layers of jet holes 103. These at least two layers of jet holes 103 are connected to the concentrating cavity 107, which is located between the two layers of jet holes 103. A first cavity 101 is connected to one layer of jet holes 103, and a second cavity 102 is connected to the other layer of jet holes 103. With this structure, on the one hand, the broth is emulsified through one layer of jet holes 103 before entering the concentrating cavity 107 for mixing. The mixed broth can then enter the other layer of jet holes 103 for further emulsification, improving the emulsification effect. On the other hand, the jet holes 103 are made in two layers, allowing for a shorter length and reducing the processing difficulty of the jet holes 103.

[0102] In one embodiment, please refer to Figure 14Projecting along the direction of the arrangement of the jet holes 103 in one layer and the jet holes 103 in another layer, the projected areas of the jet holes 103 in one layer and the projected areas of the jet holes 103 in another layer are at least partially offset. This structural form reduces the possibility that the soup flowing out of one layer of jet holes 103 can directly flow out of the other layer of jet holes 103, increases the resistance to the flow of the soup flowing out of one layer of jet holes 103 to the other layer of jet holes 103, and allows the soup flowing out of one layer of jet holes 103 to fully collide and mix in the energy-concentrating cavity 107 before entering the other layer of jet holes 103 for emulsification, thus obtaining a better emulsification effect.

[0103] In one embodiment, please refer to Figure 14 The projection areas of the jet holes 103 in one layer and the projection areas of the jet holes 103 in another layer are at least partially offset in the vertical direction.

[0104] In one embodiment, please refer to Figure 14 and Figure 17 The jet holes 103 in the corresponding layer between the energy-concentrating cavity 107 and the second cavity 102 are designated as first jet holes 1031, and the jet holes 103 in the corresponding layer between the energy-concentrating cavity 107 and the first cavity 101 are designated as second jet holes 1032. The sum of the minimum flow cross-sectional areas of all first jet holes 1031 is less than the sum of the minimum flow cross-sectional areas of all second jet holes 1032. With this structure, the liquid in the first cavity 101 enters the energy-concentrating cavity 107 through the second jet holes 1032 to complete one emulsification. After emulsification in the energy-concentrating cavity 107, the liquid enters the first jet holes 1031 for further emulsification. The liquid is then emulsified through the second jet holes 1032, which have a larger sum of areas, before entering the first jet holes 1031, which have a smaller sum of areas, for further emulsification. This allows the liquid flowing through the first jet holes 1031 to undergo further collision and compression, enhancing the emulsification effect.

[0105] For example, the area of ​​the minimum flow cross section of the first jet orifice 1031 is equal to the area of ​​the minimum flow cross section of the second jet orifice 1032, and the number of the first jet orifice 1031 is not greater than the number of the second jet orifice 1032.

[0106] In one embodiment, the diameter of the first jet orifice 1031 and the diameter of the second jet orifice 1032 are both less than 10 mm. The sum of the number of first jet orifices 1031 and the number of second jet orifices 1032 is less than 30 mm.

[0107] In one embodiment, please refer to Figure 3 and Figure 9The cooking appliance has an energy-concentrating ring 108 located within the first cavity 101. A jet orifice 103 is located on the side of the energy-concentrating ring 108 facing its center. The distance between the centers of the energy-concentrating rings 108 is the target distance, which gradually decreases from bottom to top. The jet orifice 103 is located at the upper end of the energy-concentrating ring 108. With this structure, when the liquid in the first cavity 101 boils and generates rising steam, the energy-concentrating ring 108, which converges from bottom to top, can gather and concentrate the rising steam, causing the extrusion energy to concentrate at the upper end of the energy-concentrating ring 108, approximately at the location of the jet orifice 103. This allows the liquid flowing through the jet orifice 103 to be better emulsified.

[0108] In one embodiment, please refer to Figure 3 and Figure 9 The energy-concentrating ring 108 and the jet orifice 103 are formed in the emulsifying device 2.

[0109] In one embodiment, please refer to Figure 3 and Figure 9 The energy-concentrating ring 108 is formed on the separator 23.

[0110] It is understandable that cooking appliances may not have the energy-concentrating ring 108.

[0111] In one embodiment, please refer to Figure 1 , Figures 3-7 , Figure 9 and Figure 10 ,as well as Figures 12-19 The jet orifice 103 has at least one layer, and the surface where the inlet of each layer of jet orifice 103 is located is the target surface. The preset included angle is 30° to 45°, and the position arrangement of each layer of jet orifice 103 satisfies any one of the following arrangements:

[0112] The angle between the tangent plane of the target surface corresponding to the inlet location of all jet holes 103 in the corresponding layer and the horizontal plane is not greater than the preset angle;

[0113] The angle between the tangent plane of the target surface corresponding to the inlet location of all jet holes 103 in the corresponding layer and the horizontal plane is greater than the preset angle;

[0114] The angle between the tangent plane of the target surface corresponding to the inlet location of at least one jet hole 103 in the corresponding layer and the horizontal plane is not greater than a preset angle, while the angle between the tangent plane corresponding to the inlet location of at least one jet hole 103 in the corresponding layer and the horizontal plane is greater than a preset angle.

[0115] Each of these is a positional arrangement of the jet holes 103, and all of these jet holes 103 exhibiting these positional arrangements are capable of emulsifying the soup.

[0116] It should be noted that the target surface is the surface between the first cavity 101 and the second cavity 102 and away from the second cavity 102.

[0117] It should be noted that when the number of jet orifice 103 layers is at least two, the target surface corresponding to each layer includes the common surface of each layer between the first cavity 101 and the second cavity 102, as well as the independent surface of each layer. The common surface is located between the first cavity 101 and the second cavity 102, and there is no energy-concentrating cavity 107 between the two layers of jet orifice 103 on the side of the common surface facing the first cavity 101 and the side of the common surface facing the second cavity 102.

[0118] For example, please refer to Figure 1 , Figures 3-7 , Figure 9 , Figure 10 , Figure 12 , Figure 13 , Figure 15 , Figure 16 , Figure 18 and Figure 19 The jet orifice 103 has one layer, and the target surface where the inlet of the jet orifice 103 is located is the surface of the emulsifying device 2 located between the first cavity 101 and the second cavity 102, away from the second cavity 102.

[0119] For example, please refer to Figure 14 and Figure 15 The jet orifice 103 has two layers. The jet orifice 103 in the corresponding layer between the energy focusing cavity 107 and the second cavity 102 is the first jet orifice 1031, and the jet orifice 103 in the corresponding layer between the energy focusing cavity 107 and the first cavity 101 is the second jet orifice 1032. The common surface P1 of the corresponding layer of the first jet orifice 1031 and the corresponding layer of the second jet orifice 1032 is located between the first cavity 101 and the second cavity 102 and is away from the second cavity 102. There is no energy focusing cavity 107 between the two layers of jet orifices 103 on the side of the common surface facing the first cavity 101 and the side of the common surface facing the second cavity 102. The independent surface of the layer corresponding to the first jet orifice 1031 is the first surface P2, which is located between the energy-concentrating cavity 107 and the second cavity 102 and faces away from the second cavity 102. The independent surface of the layer corresponding to the second jet orifice 1032 is the second surface P3, which is located between the energy-concentrating cavity 107 and the first cavity 101 and faces away from the second cavity 102. The common surface P1 and the first surface P2 constitute the target surface where the inlet of the first jet orifice 1031 of the corresponding layer is located. The common surface P1 and the second surface P3 constitute the target surface where the inlet of the second jet orifice 1032 of the corresponding layer is located. The area of ​​the overlapping part of the second surface P3 and the common surface P1 is not calculated repeatedly; only the area corresponding to the common surface is calculated for the overlapping part.

[0120] For example, the number of layers of jet holes 103 is three or more, the energy focusing cavity 107 is divided into multiple sub-cavities, and a layer of jet holes 103 is provided between two adjacent sub-cavities. Except for the independent surface of the layer corresponding to the first jet hole 1031 and the independent surface of the layer corresponding to the second jet hole 1032, the independent surface of the corresponding layer of each other layer of jet holes 103 is located between two sub-cavities adjacent to the jet hole 103 of the corresponding layer, and the independent surface of the corresponding layer is located at the inlet end of the jet hole 103 of the corresponding layer.

[0121] It is understandable that the angle between the tangent plane of the target surface corresponding to the inlet location of all jet holes 103 in the corresponding layer and the horizontal plane is not greater than a preset angle. The tangent plane of the target surface at the inlet location of the jet hole 103 is relatively close to the horizontal plane. The pressure formed at the jet hole 103 by the steam generated by the boiling of the soup in the first cavity 101 is relatively large, which is conducive to the soup in the first cavity 101 being squeezed into the jet hole 103, so that the fat and protein in the soup collide and emulsify.

[0122] It is understandable that the angle between the tangent plane of the target surface corresponding to the inlet location of all jet holes 103 in the corresponding layer and the horizontal plane is greater than the preset angle. The tangent plane of the target surface at the inlet location of the jet hole 103 is relatively close to the vertical plane. The pressure formed at the jet hole 103 by the steam generated by the boiling of the soup in the first chamber 101 is relatively small. The impact force of the soup flowing into the second chamber 102 through the jet hole 103 is relatively small, and the direction of the soup flowing out of the jet hole 103 is relatively close to the horizontal plane. The risk of soup overflow is small, and cooking is relatively safe.

[0123] Understandably, the angle between the tangent plane of the target surface corresponding to the inlet location of at least one of the jet holes 103 in the corresponding layer and the horizontal plane is not greater than a preset angle, while the angle between the tangent plane corresponding to the inlet location of at least one of the jet holes 103 in the corresponding layer and the horizontal plane is greater than a preset angle. The tangent plane of the target surface at the inlet location of some jet holes 103 is closer to the horizontal plane, and the tangent plane of the target surface at the inlet location of some jet holes 103 is closer to the vertical plane, allowing the liquid in the first cavity 101 to flow into the jet holes 103 from various directions for emulsification as much as possible.

[0124] The shape of the flow cross section of the jet orifice 103 is not limited.

[0125] In one embodiment, please refer to Figures 20-24 The shape of the jet orifice 103 is any one of the following:

[0126] The jet orifice 103 is a straight orifice;

[0127] Along the extension direction of the jet orifice 103, the area of ​​the flow cross section of the jet orifice 103 gradually decreases or alternates from the inlet of the jet orifice 103 to the outlet of the jet orifice 103.

[0128] The centerline of the jet orifice 103 is a curve;

[0129] The jet orifice 103 includes a main orifice 1033 and a plurality of branch orifices 1034 communicating with the main orifice 1033. The inlet of the jet orifice 103 is located in the main orifice 1033.

[0130] The shape of the jet orifice 103 can be selected according to actual needs.

[0131] When the jet orifice 103 is a straight orifice, the flow velocity of the soup through the jet orifice 103 is relatively fast and the resistance is relatively small.

[0132] For example, the jet orifice 103 can be a cylindrical orifice extending in a straight line.

[0133] When the centerline of the jet orifice 103 is curved, the flow direction of the soup in the jet orifice 103 will change, which can increase the flow resistance of the soup in the jet orifice 103, so that the fat and protein in the soup can fully collide and impact in the jet orifice 103 to improve the emulsification effect in a shorter time.

[0134] It should be noted that the curve can be a relatively smooth curve with a continuously changing curvature. The curve can also be a multi-segment bend.

[0135] For example, please refer to Figure 20 The jet orifice 103 is bent at a 90-degree angle.

[0136] Please see Figure 22 As the jet orifice 103 extends, the cross-sectional area of ​​the jet orifice 103 alternates between its inlet and outlet. The liquid continuously flows alternately between larger and smaller spaces, allowing the fat and protein particles in the liquid to collide and impact repeatedly, thereby improving the emulsification effect in a shorter time.

[0137] Please see Figure 23 As the jet orifice 103 extends, the cross-sectional area of ​​the jet orifice 103 gradually decreases from its inlet to its outlet. During the flow of the liquid within the jet orifice 103, the space is continuously compressed and the flow rate increases, which facilitates the collision and impact of fats and proteins in the liquid, thereby improving the emulsification effect in a shorter time.

[0138] In one embodiment, please refer to Figure 21 The area of ​​the flow cross section of the jet orifice 103 first increases and then decreases.

[0139] Please see Figure 24 When the jet orifice 103 includes a main orifice 1033 and multiple branch orifices 1034 communicating with the main orifice 1033, the inlet of the jet orifice 103 is located in the main orifice 1033. The liquid flows in through the main orifice 1033 and flows from the main orifice 1033 to the branch orifices 1034 with smaller cross-sectional areas, further emulsifying the liquid flowing out of the main orifice 1033 through the smaller branch orifices 1034.

[0140] In one embodiment, the cross-sectional shape of the jet hole 103 can be a regular or irregular shape such as square, ellipse or rhombus.

[0141] In one embodiment, the maximum particle size of water-soluble fat is the target particle size, which is 0.05 mm to 0.15 mm. It is understood that fat with a particle size not larger than the target particle size is soluble in water.

[0142] In one embodiment, a circle with the target particle size as its diameter is designated as the critical circle, the area of ​​the critical circle is designated as the critical area, the included angle is preset to be 30° to 45°, the number of jet holes 103 layers is at least one, the sum of the areas of the minimum flow cross sections of all jet holes 103 corresponding to each layer is designated as the first area, and each layer of jet holes 103 satisfies any one of the following conditions:

[0143] The diameter of each jet hole 103 in the corresponding layer is no larger than the target particle size;

[0144] The area of ​​the minimum flow cross section of each jet hole 103 in the corresponding layer is not greater than the critical area;

[0145] First proportional term: The cross-sectional shape of the jet hole 103 of the corresponding layer is circular. The diameter of the cross-section at any two positions on the center line of the jet hole 103 of the corresponding layer is equal. The ratio of the length of the center line of the jet hole 103 of the corresponding layer to the diameter of the corresponding jet hole 103 is greater than or equal to 1. The surface where the inlet of the jet hole 103 of the corresponding layer is located is the target surface. The target surface is away from the second cavity 102. The target surface includes the first target surface. The angle between the tangent plane of the first target surface and the horizontal direction is not greater than the preset angle. The projected area of ​​the first target surface along the vertical direction is the second area. The inlets of all jet holes 103 of the corresponding layer are located on the first target surface. The ratio of the first area to the second area of ​​the corresponding layer is not greater than 50%.

[0146] Second proportional term: The cross-sectional shape of the jet hole 103 of the corresponding layer is circular. The diameter of the cross-section at any two positions on the center line of the jet hole 103 of the corresponding layer is equal. The ratio of the length of the center line of the jet hole 103 of the corresponding layer to the diameter of the corresponding jet hole 103 is greater than or equal to 1. The surface where the inlet of the jet hole 103 of the corresponding layer is located is the target surface. The target surface is away from the second cavity 102. The target surface includes the second target surface. The angle between the tangent plane of the second target surface and the horizontal direction is greater than the preset angle. The area of ​​the second target surface is the third area. The inlets of all jet holes 103 of the corresponding layer are located on the second target surface.

[0148] Fourth proportional item: The surface where the inlet of the jet hole 103 of the corresponding layer is located is the target surface. The target surface is away from the second cavity 102. The target surface includes a first target surface. The angle between the tangent plane of the first target surface and the horizontal direction is not greater than a preset angle. The projected area of ​​the first target surface along the vertical direction is the second area. The inlet of all jet holes 103 of the corresponding layer is located on the first target surface. The ratio of the first area to the second area of ​​the corresponding layer is not greater than 10% or not greater than 2%.

[0149] Fifth proportional item: The surface where the inlet of the jet hole 103 of the corresponding layer is located is the target surface. The target surface is away from the second cavity 102. The target surface includes the second target surface. The angle between the tangent plane of the second target surface and the horizontal plane is greater than the preset angle. The area of ​​the second target surface is the third area. The inlet of all jet holes 103 of the corresponding layer is located on the second target surface. The ratio of the first area to the third area of ​​the corresponding layer is not greater than 10% or not greater than 2%.

[0150] The sixth proportional item: The surface where the inlet of the jet hole 103 of the corresponding layer is located is the target surface. The target surface is away from the second cavity 102. The target surface includes a first target surface and a second target surface that are connected to each other. The angle between the tangent plane of the first target surface and the horizontal plane is not greater than a preset angle. The projected area of ​​the first target surface in the vertical direction is the second area. The angle between the tangent plane of the second target surface and the horizontal plane is greater than a preset angle. The area of ​​the second target surface is the third area. Among all the jet holes 103 of the corresponding layer, the inlet of at least one jet hole 103 is located on the first target surface, and the inlet of at least one jet hole 103 is located on the second target surface. The ratio of the first area of ​​the corresponding layer to the sum of the second area and the third area is not greater than 7% or not greater than 1.5%.

[0151] When the jet orifice 103 meets any of these conditions, the soup can produce a good jetting effect when flowing through each layer of jet orifice 103, so that the soup flows relatively quickly in the jet orifice 103, promoting the collision and impact of protein and fat particles in the soup, which is beneficial to improve the emulsification effect of the soup in a shorter time.

[0152] It is understandable that the diameter of each jet hole 103 in the corresponding layer is not greater than the target particle size. The boiling of the soup in the first chamber 101 generates steam, which pushes the soup in the first chamber 101 towards the jet hole 103. The fat and protein in the soup collide and impact each other, so that the fat particle size is not greater than the target particle size. Fat particles smaller than the target particle size can dissolve better in water, so that the fat can be better dispersed in water, forming an emulsion state of water and milk blending.

[0153] It is understandable that the minimum flow cross-sectional area of ​​each jet orifice 103 in the corresponding layer is not greater than the critical area. When the flow cross-section of the jet orifice 103 is circular, the diameter of the corresponding jet orifice 103 is smaller than the target diameter. When the flow cross-section of the jet orifice 103 is non-circular, fat particles larger than the target particle size are more difficult to pass through the jet orifice 103 whose minimum flow cross-sectional area is not greater than the critical area. Therefore, the particle size of fat particles impacted by the jet flowing through this type of jet orifice 103 will be smaller than the target particle size, allowing the fat to dissolve better in water and thus forming an emulsified state of water and milk.

[0154] It is understandable that the angle between the tangent plane of the first target surface and the horizontal direction is not greater than the preset angle, the tangent plane of the first target surface is close to the horizontal plane, and the inlet of all jet holes 103 of the corresponding layer is located on the first target surface. When the ratio of the first area to the second area of ​​the corresponding layer is not greater than 10% or not greater than 2%, the jet holes 103 of this layer located on the first target surface have a better jetting effect.

[0155] In particular, when the ratio of the first area to the second area is no more than 2%, the jetting effect generated by the liquid flowing through the jetting hole 103 at the inlet on the first target surface is more obvious, and the emulsification effect of the liquid is greatly improved in a short time.

[0156] For example, the ratio of the first area to the second area can be 0.01%, 0.02%, 0.05%, 0.07%, 0.1%, 0.5%, 1%, 2%, 3%, 5%, 7%, 8%, or 10%.

[0157] Understandably, the boiling liquid in the first cavity 101 generates steam that forces the liquid into the jet orifice 103. Since the tangential plane of the first target surface is nearly horizontal, the pressure exerted by the boiling liquid and steam on the first target surface and at the inlet of the jet orifice 103 is relatively high. This pressure is beneficial for the emulsification of fats and proteins in the liquid through collision and impact. However, the high pressure also poses a risk of liquid overflow. In one embodiment, the ratio of the first area to the second area in the fourth proportional term is not less than 0.05%. With this structural configuration, appropriately increasing the ratio of the first area to the second area can reduce the force pushing the liquid in the first cavity 101 towards the inlet of the jet orifice 103, thus reducing the risk of liquid overflow.

[0158] It is understandable that the angle between the tangent plane of the second target surface and the horizontal plane is greater than the preset angle, the tangent plane of the second target surface is close to the vertical plane, the inlet of the jet hole 103 of the corresponding layer is located on the second target surface, and when the ratio of the first area to the third area of ​​the corresponding layer is not greater than 10% or not greater than 2%, the jet hole 103 of this layer located on the second target surface has a better jetting effect.

[0159] In particular, when the ratio of the first area to the third area is no more than 2%, the jetting effect generated by the liquid flowing through the jetting hole 103 at the inlet on the second target surface is more obvious, and the emulsification effect of the liquid is greatly improved in a short time.

[0160] It is understandable that the pressure exerted by the first cavity 101 on the jet hole 103, where the inlet is located on the second target surface, to push the soup towards the jet hole 103 is relatively small, which helps to reduce the risk of soup overflow.

[0161] It is understandable that in the corresponding layer of jet holes 103, when the inlet of some jet holes 103 is located on the first target surface and the inlet of some jet holes 103 is located on the second target surface, both the first and second target surfaces have a certain influence on the pressure of the liquid flowing through the jet holes 103. The area ratio needs to take into account the sum of the second and third areas, and the corresponding ratio can be appropriately reduced. The ratio of the first area of ​​the corresponding layer to the sum of the second and third areas is not greater than 7% or not greater than 1.5%, so that this layer of jet holes 103 has a better jet emulsification effect.

[0162] In particular, when the ratio of the first area of ​​the corresponding layer to the sum of the second and third areas is no more than 1.5%, the jetting effect generated by the liquid flowing through the jetting hole 103 of this layer is more obvious, and the emulsification effect of the liquid is greatly improved in a short time.

[0163] It is understandable that the cross-sectional shape of the flow passage of the corresponding layer's jet orifice 103 is circular, the diameter of the cross-section at any two positions on the centerline of the corresponding layer's jet orifice 103 is equal, and the ratio of the length of the centerline of the corresponding layer's jet orifice 103 to the diameter of the corresponding jet orifice 103 is greater than or equal to 1. These jet orifices 103 are relatively long and slender, allowing the liquid to flow rapidly within them. This facilitates the interaction of fats and proteins in the liquid, improving the emulsification effect. The range of area ratios for these long and slender orifices can be appropriately relaxed.

[0164] For a relatively slender jet orifice 103, the ratio of the first area to the second area of ​​the corresponding layer is not greater than 50%, the ratio of the first area to the third area of ​​the corresponding layer is not greater than 50%, or the ratio of the first area to the sum of the second and third areas of the corresponding layer is not greater than 30%, so that the jet orifice 103 of the corresponding layer has a better emulsification effect in a shorter time.

[0165] For example, please refer to Figure 1 , Figures 3-6 , Figure 9 , Figure 12 and Figure 18 The jet orifice 103 has one layer, and the inlet of the jet orifice 103 is located on the first target surface, which is parallel to the horizontal plane.

[0166] For example, please refer to Figure 7 , Figure 13 , Figure 15 and Figure 16 The jet hole 103 has one layer, and the inlet of the jet hole 103 is located on the second target surface, which is perpendicular to the horizontal plane.

[0167] For example, please refer to Figure 14 The jet orifice 103 has two layers. The inlet of the first jet orifice 1031 is located on the first target surface of the target surface of the corresponding layer, and the inlet of the second jet orifice 1032 is located on the first target surface of the target surface of the corresponding layer. The first target surface is parallel to the horizontal plane.

[0168] For example, please refer to Figure 17The jet orifice 103 has two layers. The inlet of the first jet orifice 1031 is located on the second target surface of the target surface of the corresponding layer. The second target surface is perpendicular to the horizontal plane. The inlet of the second jet orifice 1032 is located on the first target surface of the target surface of the corresponding layer. The first target surface is parallel to the horizontal plane.

[0169] For example, please refer to Figures 1-9 , Figure 12 as well as Figure 18 The figure shows that the jet orifice 103 has one layer. The cross-sectional shape of the jet orifice 103 in the corresponding layer is circular. The diameter of the cross-section at any two positions on the center line of the jet orifice 103 in the corresponding layer is equal. The ratio of the length of the center line of the jet orifice 103 in the corresponding layer to the diameter of the corresponding jet orifice 103 is greater than or equal to 1. The jet orifice 103 shown in the figure is relatively slender.

[0170] In one embodiment, when the jet orifice 103 satisfies any one of the first proportional term, second proportional term, third proportional term, fourth proportional term, fifth proportional term, and sixth proportional term, the orifice diameter of the minimum flow cross-section of the jet orifice 103 is 0.5mm to 20mm or 1mm to 6mm, or the area of ​​the minimum flow cross-section of the jet orifice 103 is π*0.0625mm². 2 ~π*100mm 2 or π*0.25mm 2 ~π*9mm 2 With this structural form, under the premise of satisfying any proportional term, the size of the jet orifice 103 is appropriately limited to prevent a single jet orifice 103 from being too large, which is conducive to improving the jet emulsification effect of the jet orifice 103.
