Description
Technical Field
[0001] This invention relates to the field of intelligent health cup cooking control technology, specifically to an intelligent health cup multi-mode cooking control device. Background Technology
[0002] In today's fast-paced life, people are increasingly pursuing health and wellness, and the quality of homemade beverages and medicinal stews has become a key focus. The processes of ingredient preparation, herbal tea brewing, and medicinal stew preparation are crucial to the home-based wellness experience and have a vital impact on people's quality of life. Against this backdrop, the smart health-preserving cup has emerged, offering a more convenient and intelligent stewing and cooking experience with its unique advantages and innovative functions.
[0003] The biggest highlight of the smart health-preserving cup lies in its multi-mode intelligent control and voice interaction function, an innovative technology that revolutionizes the traditional way of operating health-preserving cups. Users can easily operate various modes of the cup with simple voice commands, eliminating the need for manually pressing buttons to switch functions repeatedly. For example, when brewing herbal tea, simply say "Start herbal tea mode," and the cup will immediately respond and start the herbal tea brewing program. Furthermore, users can precisely set the brewing temperature and duration using voice commands, such as "Set the brewing temperature to 85℃ and brew for 20 minutes," and the cup will automatically adjust the operating parameters. This convenient operation greatly enhances the user experience, making it especially suitable for the elderly and busy working professionals.
[0004] Existing conventional smart health-preserving cups lack a regular flow channel for the liquid during stewing and cooking. This results in uneven heating of the ingredients, with localized overheating at the bottom leading to scorching. Furthermore, large pieces of food residue easily float to the top of the cup during stewing, clogging the steam vents. The upper layers of food also receive insufficient heating, leading to poor overall stewing results and incomplete release of flavor and nutrients. Traditional health-preserving cups mostly rely on fixed heating levels, with the liquid inside the inner liner relying solely on natural heat convection. The lack of active stirring to guide liquid circulation makes it easy for medicinal herbs, flowers, and root vegetables to sink to the bottom and burn. Residue floating with the steam can also contaminate the rim, resulting in significant cleaning and maintenance work, highlighting clear technical shortcomings. Summary of the Invention
[0005] The purpose of this invention is to provide a smart health cup multi-mode cooking control device to solve the problems in the prior art, such as poor liquid convection, food sticking to the bottom, residue floating and clogging the steam outlet, and inconvenient mode switching operation.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a smart health cup multi-mode cooking control device, comprising a health cup body, a voice receiving module disposed on the surface of the health cup body, a main controller disposed at the bottom of the voice receiving module, the main controller disposed on the front surface of the health cup body, a temperature sensor disposed inside the health cup body, a heating and cooking mechanism disposed inside the health cup body, a dustproof protection mechanism for the cup mouth disposed on the top of the health cup body, and a touch display screen disposed on the surface of the health cup body.

[0012] Preferably, the cup mouth dustproof protection mechanism includes a cup mouth, which is fixedly connected to the top of the health cup body, and a dustproof filter is fixedly connected to the bottom of the mounting bracket.
[0013] Preferably, a support rod is fixedly connected to the top of the assembly bracket, and a positioning frame is fixedly connected to the middle of the support rod, with the positioning frame positioned directly above the main body of the health cup.

[0015] Preferably, the dust filter is disposed inside the cup opening, and the surface of the dust filter has uniformly sized air filtration holes.
[0016] Compared with the prior art, the present invention provides a smart health cup multi-mode cooking control device, which has the following beneficial effects:
[0017] 1. This smart health-preserving cup features a multi-mode cooking control device. Through the coordinated action of the first and second flow guide vanes and the circulating fan blades, a stable liquid convection channel is created inside the inner container, driving the liquid to circulate along a set path. During this process, larger food residues collide with the inner wall of the conical baffle and fall back to the bottom of the inner container under gravity, rejoining the heating and cooking process. This structure prevents large food residues from floating directly to the rim and causing blockages, while also ensuring more even heating of the food inside the inner container, reducing the probability of food burning at the bottom, and guaranteeing the optimal cooking effect of the health-preserving cup, resulting in a more complete release of flavor and nutrients from the ingredients.
[0018] 2. This smart health cup features a multi-mode cooking control device. Through its dust filter, it can prevent external dust and debris from entering the main body of the health cup, thus avoiding contamination of the food and soup inside the inner pot. Furthermore, when the dust filter becomes clogged with residue, it can be quickly disassembled for cleaning, ensuring its normal use.
[0019] 3. This smart health cup features a multi-mode cooking control device. The voice receiving module collects the user's voice command signals and transmits them to the main controller. Upon receiving the command, the main controller responds quickly, switching between corresponding cooking modes such as herbal tea, medicinal cuisine, and nourishing soups, driving the main body of the health cup to operate. At the same time, the temperature sensor collects the inner pot temperature in real time, realizing automatic adjustment of heating power, improving the intelligent operation level of the device, and optimizing the user's home health care experience.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Example 1: Stewing Example in Flower Tea Mode
[0033] Combination Figures 1 to 8A smart health cup multi-mode cooking control device includes a health cup body 1, a voice receiving module 4 on the surface of the health cup body 1, a main controller 5 at the bottom of the voice receiving module 4, the main controller 5 being located on the front surface of the health cup body 1, a temperature sensor 7 inside the health cup body 1, a heating and cooking mechanism 2 inside the health cup body 1, a dustproof protection mechanism 3 at the top of the health cup body 1, and a touch display screen 6 on the surface of the health cup body 1.
[0034] The heating and cooking mechanism 2 includes a food container 26, which is fixedly connected to the bottom of the health cup body 1. A stirring shaft 29 is provided inside the food container 26, and a stirring blade 202 is fixedly connected to the surface of the stirring shaft 29. The stirring blade 202 is located inside the food container 26. A positioning support 27 is fixedly connected to the upper edge of the food container 26. An electromagnetic heating element 205 is fixedly connected to the side of the positioning support 27 near the center of the food container 26. A fixed support member 21 is fixedly connected to the top of the food container 26. A second flow guide baffle 204 is fixedly connected to the inner wall of the fixed support member 21. The second flow guide baffle 204 is located above the electromagnetic heating element 205.
[0035] Furthermore, a stirring shaft 29 extends through the bottom of the health cup body 1, and a drive motor 203 is fixedly connected to the bottom of the stirring shaft 29. The drive motor 203 is also fixedly connected to the bottom of the health cup body 1. A fixed inner ring 23 is fixedly connected inside the fixed support member 21, and an auxiliary heating plate 24 is fixedly connected to the surface of the fixed inner ring 23. A conical baffle 22 is provided inside the fixed inner ring 23, and the conical baffle 22 is fixedly connected inside the fixed support member 21 with its opening facing upwards. The stirring shaft 29 passes through the conical baffle cylinder 22; a circulating fan blade 201 is fixedly connected to the surface of the stirring shaft 29, and the circulating fan blade 201 is disposed inside the conical baffle cylinder 22; a support bracket 28 is rotatably connected to the top of the stirring shaft 29, and the support bracket 28 is fixedly connected to the top of the conical baffle cylinder 22; a first guide baffle 25 is fixedly connected to the inner wall of the conical baffle cylinder 22, and the number of the first guide baffles 25 is several, and the several first guide baffles 25 are distributed in a ring at equal intervals.
[0036] This embodiment is used for brewing flower tea. The flower tea ingredients and purified water are placed inside the inner pot. The user can give the voice command "Start Flower Tea Mode". The voice receiving module collects the voice signal and transmits it to the main controller. The main controller retrieves the preset parameters for the flower tea mode. The flower tea mode is set to a temperature of 85℃ and a brewing time of 15 minutes. The temperature sensor collects the water temperature inside the inner pot in real time, and the data is output to the touch screen for visualization.
[0037] The main controller starts the drive motor, which drives the stirring shaft to rotate. The stirring blades rotate at low speed, gently agitating the tea and water inside the inner pot to prevent the tea from settling. Simultaneously, the stirring shaft drives the circulating fan blades to rotate, which in turn drives the liquid inside the inner pot through the container and the conical baffle to form a circulation flow. Under the combined action of the first and second guide baffles and the circulating fan blades, a complete liquid convection channel is formed, driving the liquid in the cup to circulate vertically. At this time, some large pieces of petal residue will come into contact with and collide with the inner wall of the conical baffle, and fall back to the bottom of the container under the influence of gravity, participating in the heating and stewing again, preventing large pieces of petal residue from floating directly to the top and clogging the steam filter of the dustproof filter screen at the cup opening.
[0038] The electromagnetic heating element is the main heating source, while the auxiliary heating plate helps compensate for the heat from the upper part, reducing the temperature difference between the top and bottom of the inner pot. When the temperature sensor detects that the water temperature has reached the set 85℃, the main controller automatically reduces the heating power to maintain a constant temperature for timed stewing. After the timer ends, it automatically switches to the keep-warm setting. The steam generated during stewing rises through the dust filter and is discharged outwards.
[0039] The dust filter is installed inside the limiting slot at the mouth of the cup and is positioned by the mounting bracket, support rod and positioning frame. Small tea residues will be trapped by the filter. After brewing, lift the positioning frame upwards to remove the mounting bracket and the dust filter as a whole. Rinse and clean the trapped petal residues directly. After cleaning, insert it back into the limiting slot to complete the assembly reset.
[0040] Example 2: Stewing of Root and Rhizome Ingredients for Medicinal Cuisine
[0041] See Figure 9 Based on Example 1, this example focuses on stewing root and rhizome medicinal ingredients such as wolfberry, astragalus, and codonopsis. These ingredients have a relatively hard texture, requiring higher temperatures and longer stewing times. They tend to sink to the bottom and become gelatinized, resulting in more broken pieces and residues.
[0042] The cup mouth dustproof protection mechanism 3 includes a cup mouth 32, which is fixedly connected to the top of the health cup body 1. A limiting groove is opened on the inner side of the cup mouth 32, and an assembly bracket 31 is inserted into the limiting groove. A dustproof filter screen 33 is fixedly connected to the bottom of the assembly bracket 31. The dustproof filter screen 33 is set inside the cup mouth 32, and the surface of the dustproof filter screen 33 has uniformly sized steam filtering holes. A support rod 35 is fixedly connected to the top of the assembly bracket 31, and a positioning frame 34 is fixedly connected to the middle of the support rod 35. The positioning frame 34 is set directly above the health cup body 1.
[0043] The working process of this embodiment is as follows: The chopped medicinal root and stem ingredients and water are put into the inner pot of the container, and the user gives the voice command "Start medicinal mode"; the main controller calls the medicinal mode, sets the stewing temperature to 98℃, and the stewing time to 40 minutes; the drive motor speed is appropriately increased, the stirring blades increase the stirring amplitude, and the speed of the circulating fan blades is increased simultaneously to enhance the internal liquid circulation and convection of the inner pot; the first guide baffle and the second guide baffle, together with the conical baffle, block large pieces of food debris that have fallen off the root and stem, causing them to fall back to the bottom of the inner pot and preventing the debris from floating up and clogging the steam filter hole.
[0044] The electromagnetic heating element and auxiliary heating plate work together to quickly raise the temperature; a temperature sensor continuously monitors the inner pot temperature, and once it approaches boiling, the power is reduced to maintain a gentle simmering state, minimizing the amount of foam that rises due to violent bubbling. Steam generated during the simmering process is filtered through a dust filter before being discharged; after the medicinal cuisine mode ends, it automatically enters a 70℃ keep-warm mode.
[0045] After the medicinal food is cooked, simply lift the positioning frame upwards to remove the assembly bracket and dust filter screen as a whole. The medicinal food debris intercepted by the filter screen can be rinsed directly. The stirring blades inside the inner pot can be disassembled along with the structure, making it easy to clean the medicinal food residue adhering to the bottom of the inner pot.
[0046] Example 3: Nourishing Soup Mode, Large-Capacity Stewing Example for Multiple Servings
[0047] This embodiment is suitable for stewing nourishing soups for multiple people. The inner pot contains a large volume of soup and a variety of ingredients, including meat and medicinal ingredients. The large volume of soup makes it more prone to uneven heating and the floating of foam and residue.
[0048] In this mode, the main controller controls the drive motor to rotate intermittently, the stirring shaft rotates in both directions intermittently, and the stirring blades stir intermittently. This achieves liquid circulation and convection without causing excessive and violent stirring that would lead to a large amount of soup boiling over. The circulating fan blades rotate intermittently with the shaft, working in conjunction with the first and second guide vanes to continuously build a circulating flow field. Large pieces of meat, bones, and other food residues fall back to the bottom of the inner liner after hitting the inner wall of the conical turbulence cylinder, reducing the probability of residues floating to the surface.
[0049] A temperature sensor collects the temperature in real time, and the main controller dynamically adjusts the output power of the electromagnetic heating element and auxiliary heating plate based on the detected temperature, starting with high heat to bring it to a boil and then switching to low heat for simmering. The touch screen displays the current mode, inner pot temperature, and remaining cooking time in real time.
[0050] Users can issue mode commands via voice or manually modify temperature and cooking time parameters directly through the touch screen. The device supports voice status queries, such as asking "What is the current temperature?" The voice receiving module receives the command, the main controller retrieves sensor data, and announces the real-time temperature of the inner pot through the built-in voice broadcast module.
[0051] It automatically keeps warm after stewing; the dustproof and protective mechanism at the mouth of the cup still serves to block impurities and intercept foam and residue; the entire set, including the bracket and dustproof filter, can be removed and cleaned as a whole.
[0052] In the actual operation of all the above embodiments, the temperature sensor detects the temperature of the soup inside the inner pot in real time. The detected data can be displayed on the touch screen and fed back to the main controller. The main controller controls the drive motor to drive the stirring shaft and stirring blades to rotate. At this time, the stirring blades can fully stir and mix the ingredients and water inside the inner pot, so that the ingredients can be fully dissolved. Since the outer periphery of the conical baffle is equipped with an auxiliary heating plate, in conjunction with the electromagnetic heating element, the liquid inside the inner pot can be heated evenly. While the stirring shaft rotates, it drives the circulating fan blades to rotate. Under the action of the circulating fan blades, the liquid inside the inner pot is driven to circulate through the inner pot and the conical baffle. Under the guidance of the first and second guide baffles, a stable liquid convection channel is formed, driving the liquid in the cup to circulate along the set path. Larger food scraps will come into contact with the inner wall of the conical baffle. After colliding, they will fall back into the inner container under gravity and participate in the heating and stewing process again. This avoids the phenomenon of large food scraps floating directly to the top and clogging the cup opening, ensuring that the food is heated evenly during cooking and improving the stewing and cooking effect. Steam passes through the dust filter and is discharged outside, completing the stewing and cooking process of the health cup.
[0053] This dust filter features quick installation and removal. It prevents external dust and debris from entering the body of the health cup, thus avoiding contamination of the soup and food inside the inner pot. When the dust filter becomes clogged, it can be easily disassembled and cleaned to ensure its proper function.
[0054] When the user says "Start herbal tea mode" or other voice commands, the voice receiving module collects the audio command and sends it back to the main controller. The main controller then controls the smart health cup to switch to the corresponding cooking mode and begin operation, achieving intelligent operation. This smart health cup is equipped with a temperature sensor that monitors the temperature of the broth inside the inner pot in real time. Based on the monitored data, it can automatically adjust the heating power. For example, when the temperature inside the cup is lower than the set stewing temperature, the health cup will automatically increase the heating power; when the temperature reaches the set target temperature, the health cup can automatically reduce the heating power or enter a keep-warm mode, thereby maintaining a stable stewing temperature and providing the user with a comfortable and healthy stewing environment.
