[0001] This application relates to the field of small household appliances, and particularly to a cup lid assembly and a cooking machine. Background Art

[0002] With the increasing improvement of people's living standards, many different types of cooking machines have emerged in the market. The functions of the cooking machine mainly can include, but are not limited to, making soy milk, squeezing fruit juice, making rice paste, mincing meat, making shaved ice, making coffee, and / or preparing facial masks, etc. The cooking machine can include machines for crushing and stirring food such as a soy milk machine, a blender, or a wall-breaking cooking machine. Related cooking machines include a cup lid assembly. The cup lid assembly is provided with a vent hole. The vent hole communicates the external space with the space inside the cooking machine. When the cooking machine heats and boils food materials, the slurry is likely to overflow from the vent hole. This not only affects the customer experience but also causes waste of food materials. Summary of the Invention

[0003] This application provides a cup lid assembly and a cooking machine that can prevent food materials from overflowing.

[0004] This application provides a cup lid assembly for assembling to a cup body. The cup lid assembly includes a cup lid and a filter screen disposed on the cup lid. The filter screen is provided with a first vent hole. The cup lid is provided with a siphon channel, a liquid storage cavity, and a second vent hole. The second vent hole communicates the liquid storage cavity with the external space. The siphon channel communicates the first vent hole with the liquid storage cavity. When the slurry in the cup body is heated, it can overflow from the first vent hole, enter the liquid storage cavity through the siphon channel. The slurry in the liquid storage cavity can flow back into the cup body through the siphon channel and the first vent hole. The cross-sectional area of the siphon channel is greater than or equal to the total area of the first vent holes.

[0005] In some embodiments, with the setting of the liquid storage cavity in the above technical solution, a large amount of the overflowed foam is converted into slurry after passing through the liquid storage cavity, preventing the foam from overflowing from the second vent hole in a large volume, effectively preventing food materials from overflowing, facilitating high-power boiling of food materials, and having a better taste; at the same time, the food materials in the liquid storage cavity can flow back to avoid waste and prevent a large amount of food materials from remaining in the liquid storage cavity, affecting the user experience; furthermore, defoaming can also occur during the reflux process, and the taste of the food materials after boiling is better; the filter screen can break the foam, increasing the anti-overflow effect; at the same time, it can filter juice residues to prevent large-particle juice residues from overflowing into the liquid storage cavity and being unable to be whipped, improving the taste of the processed food materials. The cross-sectional area of the siphon channel is greater than or equal to the total area of the first vent holes, and it will not be blocked during the overflow process of the slurry, and the slurry can smoothly flow into the liquid storage cavity.

[0006] Furthermore, the cup cover also includes a connecting portion, a baffle wall arranged on the connecting portion, and a baffle wall located outside the baffle wall, the connecting portion and the baffle wall enclose the liquid storage cavity, and the baffle wall and the baffle wall enclose the siphon channel.

[0007] Furthermore, when the bottom end of the baffle wall contacts the liquid stored in the liquid storage cavity, a water seal can be formed to separate the first air outlet and the second air outlet.

[0008] In some embodiments, the above technical solution utilizes the bottom end of the baffle wall to contact the liquid stored in the liquid storage chamber to form a water seal. The formation of the enclosed space allows the cup body to form a pressure higher than the atmospheric pressure when stirring or heating. The food is easier to crush in the cup body, which is more conducive to the cooking of the food, speeding up the cooking speed of the ingredients. There is no need to set up an air pump, and micro-pressure cooking can be achieved, which saves costs and solves the problem that the air outlet of the air pump is easily blocked; and when the pressure in the cup body reaches a certain level, the air pressure can still leak pressure through the liquid surface of the liquid storage chamber, which is safer and more reliable than directly sealing the exhaust channel; at the same time, the overflowing foam will also be converted into a large amount of slurry after passing through the liquid storage chamber, preventing it from overflowing from the second air outlet in the form of a large volume of foam, effectively preventing the overflow of ingredients, so as to facilitate high-power cooking of ingredients with a better taste; furthermore, the water seal can also prevent noise from being discharged, so as to reduce the noise during the operation of the food processor.

[0052] Referring to Figures 1 to 3 as shown, the cooking machine includes a main body 1, a cup assembly 2 and a cup lid assembly 3. The cup assembly 2 is detachably assembled to the main body 1. The cup lid assembly 3 is detachably assembled to the cup assembly 2.

[0053] The cup assembly 2 includes a cup body 20 and a cup base assembly 21 disposed on the cup body 20. The cup base assembly 21 includes a cup base 210, a cutter shaft 211 disposed on the cup base 210, and a crushing cutter 212 and an upper clutch 213 disposed on the cutter shaft 211. The crushing cutter 212 is located inside the cup body 20.

[0054] The host 1 includes a motor 12 and a lower clutch 13 disposed on the motor shaft of the motor 12. After the cup body assembly 2 is assembled to the host 1, the lower clutch 13 is assembled with the upper clutch 213 so that the motor 12 can drive the crushing blade 212 to rotate to stir food ingredients.

[0055] In one embodiment, the cup body assembly 2 can also be integrally provided with the host 1 and is non-detachable. The crushing blade 212 is disposed on the motor shaft of the motor 12; the upper clutch 213 and the lower clutch 13 are omitted, saving costs and reducing the noise generated by the upper clutch 213 and the lower clutch 13, thereby reducing the noise during the operation of the food processor.

[0056] See Figure 4 and Figures 12 to 13 As shown, the cup cover assembly 3 includes a cup cover 31 and a filter screen 361 disposed on the cup cover 31. The filter screen 361 is provided with a first air outlet 3611. The cup cover 31 is provided with a siphon channel 31221, a liquid storage cavity 3110, and a second air outlet 31201. The siphon channel 31221 communicates the first air outlet 3611 with the liquid storage cavity 3110. The second air outlet 31201 communicates the liquid storage cavity 3110 with the external space. When the slurry in the cup body 20 is heated, it can overflow from the first air outlet 3611 and enter the liquid storage cavity 3110 through the siphon channel 31221. The slurry in the liquid storage cavity 3110 can flow back into the cup body 20 through the siphon channel 31221 and the first air outlet 3611. The cross-sectional area of the siphon channel 31221 is greater than or equal to the total area of the first air outlets 3611.

[0057] The cross-sectional area of the siphon channel 31221 refers to the cross-sectional area of the siphon channel 31221 along the horizontal direction. The total area of the first air outlets 3611 refers to the sum of the areas of the projections of all the first air outlets 3611 on the horizontal plane.

[0058] The first air outlets 3611 can be provided in multiple numbers. The second air outlets 31201 can be provided in multiple numbers.

[0059] With the provision of the liquid storage cavity 3110, a large amount of the overflowing foam will be converted into slurry after passing through the liquid storage cavity 3110, preventing it from overflowing from the second air outlet 31201 in the form of large-volume foam, effectively preventing food ingredients from overflowing, facilitating high-power cooking of food ingredients, and resulting in a better taste. At the same time, the food ingredients in the liquid storage cavity 3110 can flow back to avoid waste and prevent a large amount of food ingredients from remaining in the liquid storage cavity 3110, which may affect the user experience. Moreover, defoaming can also occur during the reflux process, making the taste of the cooked food ingredients better. The filter net 361 can break the foam, enhancing the anti-overflow effect. At the same time, it can filter juice and residue, preventing large-particle juice and residue from overflowing into the liquid storage cavity 3110 and being unable to be whipped, improving the taste of the processed food ingredients. The cross-sectional area of the siphon channel 31221 is greater than or equal to the total area of the first air outlet 3611, so it will not be blocked during the slurry overflow process, and the slurry can flow smoothly into the liquid storage cavity 3110.

[0060] Optionally, the total area of the first air outlet 3611 is equal to the sum of the areas of the filter holes on the filter net 361.

[0061] Optionally, the cup lid assembly 3 further includes a handle 33, a first sealing ring 34, a second sealing ring 35, and a filtering assembly 36 provided on the cup lid 31. The cup lid 31 includes a lower cup lid 311 and an upper cup lid 312 assembled together. The handle 33 is provided on the upper cup lid 312. The first sealing ring 34 is located between the upper cup lid 312 and the lower cup lid 311. The filter net 361 and the second sealing ring 35 are provided on the lower cup lid 311.

[0062] Optionally, the upper cup lid 312 and the lower cup lid 311 can also be integrally provided and non-detachable.

[0063] Optionally, the hardness of the upper cup lid 312 can be less than that of the lower cup lid 311, for example, it is made of silica gel, rubber, or fluororubber.

[0064] The first sealing ring 34 fits and seals with the upper cup lid 312 and the lower cup lid 311 to prevent air leakage or water leakage from the gap between the upper cup lid 312 and the lower cup lid 311. The first sealing ring 34 can be provided on the upper cup lid 312 or the lower cup lid 311. The lower cup lid 311 is assembled to the cup body 20. The second sealing ring 35 fits and seals with the lower cup lid 311 and the cup body 20 to prevent air leakage or water leakage from the gap between the lower cup lid 311 and the cup body 20. The handle 33 is assembled to the upper cup lid 312 for gripping, facilitating the picking up and placing of the cup lid assembly 3.

[0065] Optionally, the cup lid assembly 3 includes a filter net assembly 36. The filter assembly 36 is detachably assembled to the lower cup lid 311, facilitating the cleaning of the filter assembly 36.

[0066] In one embodiment, the filtering component 36 may also be integrally provided with the lower cup cover 311 and is not detachable.

[0067] See Figures 12 to 13 As shown, the lower cup cover 311 includes a connecting portion 3112 and a retaining wall 3113 provided on the connecting portion 3112. The connecting portion 3112 and the retaining wall 3113 enclose a liquid storage cavity 3110.

[0068] The upper cup cover 312 includes a retaining wall 3122. The retaining wall 3122 is located outside the retaining wall 3113. At least a part of the connecting portion 3112 is located below the retaining wall 3122. The retaining wall 3122 and the retaining wall 3113 enclose a siphon channel 31221. When the slurry in the cup body 20 overflows from the first air outlet 3611 during heating, it can enter the liquid storage cavity 3110 through the siphon channel 31221. When the temperature in the cup body 20 decreases or the crushing blade 212 stops beating the ingredients or the pressure is released, and the air pressure in the cup body 20 decreases to be less than the external air pressure, the liquid in the liquid storage cavity 3110 flows back into the cup body 20 along the siphon channel 31221 under the action of the atmospheric pressure, forming a siphon phenomenon, which can prevent the water level in the liquid storage cavity 3110 from rising continuously and prevent liquid from flowing out.

[0069] The height of the first air outlet 3611 is higher than the highest end of the liquid storage cavity 3110, and the two ends of the siphon channel 31221 are at different heights. The siphon channel 31221 is in an inverted U shape.

[0070] Optionally, the height of the first air outlet 3611 is not higher than the highest end of the liquid storage cavity 3110.

[0071] When the bottom end of the retaining wall 3122 contacts the liquid stored in the liquid storage chamber 3110, a water seal can be formed to separate the first air outlet 3611 from the second air outlet 31201. When the cup body 20 is stirred or heated, a pressure higher than the atmospheric pressure is formed, and the food is easier to be beaten and crushed in the cup body 20, which is also more conducive to the cooking of the food. When the pressure in the cup body 20 reaches a certain level, the air pressure can still be released through the liquid surface of the liquid storage chamber 3110, which is safer and more reliable than directly sealing the exhaust channel. At the same time, it can effectively prevent the noise in the cup body 20 from being discharged, so as to reduce the noise during the operation of the food processor. Furthermore, the overflowed foam will also be converted into liquid in large quantities after passing through the liquid storage chamber 3110, preventing the overflow of the second air outlet 31201 in the form of large volume of foam, and effectively preventing the slurry from overflowing. Compared with traditional food processors that use an air pump to blow air into the cup to increase the air pressure, there is no need to set up an air pump, which saves costs; at the same time, it solves the problem that the air port of the air pump is easily blocked, ensuring the smooth progress of the micro-pressure steaming of the food processor.

[0072] The liquid storage chamber 3110 is used to store liquid, which can be the slurry overflowing from the cup body 20, or the condensed water generated when the food processor is heated, or the liquid added manually. The space above the liquid surface of the liquid storage chamber 3110 is connected to the second air outlet 31201, that is, it is consistent with the external air pressure.

[0073] The width of the filter holes on the filter net 361 is less than or equal to 5 mm, so that the foam will burst when passing through the first air outlet 3611, so as to prevent a large volume of foam from entering the liquid storage cavity 3110, thereby improving the anti-overflow effect.

[0074] See also Figures 5 to 8 As shown, the lower cup cover 311 includes an assembly portion 3114 and a lower holding portion 3115 extending from the assembly portion 3114.

[0077] The connecting portion 3112 further includes a third connecting portion 31123. The third connecting portion 31123 is connected to the assembling portion 3114 and the second connecting portion 31122. The upper surface of the third connecting portion 31123 is inclined upward from the second connecting portion 31122, which helps the slurry to flow back into the liquid storage cavity 3110 along the second connecting portion 31122 and prevents food residues from remaining on the third connecting portion 31123.

[0078] The angle between the upper surface of the third connecting portion 31123 and the horizontal plane is greater than or equal to 2 degrees, which helps the slurry to flow back into the liquid storage cavity 3110 along the second connecting portion 31122.

[0079] The retaining wall 3113 includes a top 31131. The top 31131 is provided with a perforation 31132.

[0080] The filtering assembly 36 includes a holding member 360 and a filter net 361 disposed on the holding member 360.

[0081] In one embodiment, the first air outlet 3611 can also be disposed on the top 31131.

[0082] Optionally, the filter net 361 is annular and fixed to the side wall of the retaining wall 3113, and the slurry laterally enters the siphon channel 31221.

[0083] See Figures 9 to 13As shown, the upper cup cover 312 includes a top plate portion 3120, an upper holding portion 3121 extending downward from the top plate portion 3120, and a positioning post 3123 extending upward from the top plate portion 3120. The retaining wall 3122 is formed by extending downward from the top plate portion 3120. The second air outlet 31201 is located above the liquid storage cavity 3110. The second air outlet 31201 can be provided on the top plate portion 3120 or the upper holding portion 3121. The second air outlet 31201 is located outside the retaining wall 3122.

[0084] In one embodiment, the second air outlet 31201 can also be located between the upper cup cover 312 and the lower cup cover 311.

[0085] The upper holding portion 3121 is annular. The upper holding portion 3121 is provided with a plurality of groove portions 31210. The first sealing ring 34 is fixed to the upper holding portion 3121. The retaining wall 3122 encloses an annular shape. The bottom end of the retaining wall 3122 is in a flared shape, which can play a guiding role when the upper cup cover 312 and the lower cup cover 311 are assembled; at the same time, when the liquid in the liquid storage cavity 3110 is siphoned, it can ensure that a certain amount of liquid remains in the liquid storage cavity 3110 to contact the retaining wall 3122 to form a water seal, ensuring that the cooking machine is always in a water-sealed state during the entire pulping process.

[0086] When the upper cup cover 312 and the lower cup cover 311 are assembled, the upper holding portion 3121 is located in the space surrounded by the lower holding portion 3115. Rotate the upper cup cover 312 or the lower cup cover 311 so that the convex block 31151 is received in the groove portion 31210 to fix the upper cup cover 312 to the lower cup cover 311.

[0087] The upper cup cover 312 and the lower cup cover 311 can also be fixed by means of threaded connection, welding, bonding, magnetic adsorption, screw fixation, etc.

[0088] In one embodiment, the convex block 31151 can also be provided on the upper cup cover 312. Correspondingly, the groove portion 31210 is provided on the lower cup cover 311.

[0089] The bottom end of the baffle wall 3122 and the connecting portion 3112 enclose an exhaust gap 31222. The first air outlet 3611, the siphon channel 31221, the exhaust gap 31222, and the second air outlet 31201 are sequentially connected to form an exhaust passage. The position of the second air outlet 31201 is higher than the position of the exhaust gap 31222. The exhaust passage is relatively long, which extends the path when the noise is discharged and reduces the noise during the operation of the cooking machine. The baffle wall 3122 is located between the second air outlet 31201 and the first air outlet 3611. The non-linear design of the exhaust passage can prevent the slurry stirred up in the cup body 20 from splashing out directly and prevent the slurry from overflowing.

[0090] The diameter of the cavity surrounded by the retaining wall 3113 is greater than or equal to 20 mm and less than or equal to 100 mm. If it is too large, it will occupy the volume of the liquid storage cavity 3110, and if it is too small, it is not conducive to exhaust. The width W1 of the first connecting portion 31121 is greater than or equal to 5 mm and less than or equal to 20 mm. If it is too small, more liquid will remain, resulting in a poor user experience. If it is too large, it is not conducive to water sealing.

[0091] The width W2 of the siphon channel 31221 is less than or equal to 10 mm, and the siphon effect is better. Less liquid remains in the liquid storage cavity 3110, improving the user experience.

[0092] The height H of the exhaust gap 31222 is greater than or equal to 0.5 mm and less than or equal to 2.5 mm, which can prevent food residues from blocking the exhaust gap 31222 and ensure normal exhaust. At the same time, the siphon effect is better, less liquid remains in the liquid storage cavity 3110, and the user experience is improved.

[0093] In one embodiment, a plurality of liquid storage cavities 3110 can be provided, which are respectively located outside the retaining wall 3113, and the bottom end of the baffle wall 3122 is located in the liquid storage cavity 3110.

[0094] The handle 33 includes a base 330 and an upper cover 331 assembled to the base 330. The base 330 and the upper cover 331 enclose a cavity 3310, which can reduce the weight of the handle 33; at the same time, it can also prevent scalding. The base 330 is provided with an assembly hole 3301 and a through hole 3302 communicating with the assembly hole 3301. The through hole 3302 communicates the assembly hole 3301 with the cavity 3310.

[0095] When the handle 33 is assembled to the upper cup cover 312, the positioning post 3123 is assembled to the assembly hole 3301, and then a fixing member, such as a screw or a bolt, can be used to pass through the through hole 3302 and then assembled to the positioning post 3123 to fix the base 330 to the upper cup cover 312, and then the upper cover 331 is assembled to the base 330.

[0096] The second air outlet 31201 is located below the handle 33, which can hide the second air outlet 31201. When steam rushes out, it is blocked by the handle 33, preventing it from directly rushing out and burning consumers. Alternatively, the second air outlet 31201 is arranged on the side of the top plate part 3120 away from the handle 33, avoiding the handle 33 being too hot and inconvenient to hold.

[0097] The cup cover assembly 3 includes a lower cup cover 311 and an upper cup cover 312 assembled together. The cup cover 31 is double-layered, which can effectively reduce the temperature of the upper cup cover 312 to prevent scalding. The lower cup cover 311 and the upper cup cover 312 enclose a receiving cavity 3116, and the liquid storage cavity 3110 is located at the bottom of the receiving cavity 3116. The receiving cavity 3116 can store more liquid and prevent the liquid from overflowing.

[0098] See Figure 14 As shown, in another embodiment, the baffle 3122 is in a straight cylinder shape, so that the liquid in the liquid storage cavity 3110 can flow back as much as possible, avoiding the liquid remaining in the liquid storage cavity 3110 and improving the user experience.

[0099] See Figure 15 As shown, in yet another embodiment, the filter screen 361 is directly fixed to the retaining wall 3113, and the two are integrally formed. The first air outlets 3611 can be set more and can be distributed at the alternating positions of the filter screen 361 and the retaining wall 3113, and the siphon reflux effect is better.
