Description

Technical Field

[0001] This invention relates to the field of container drying technology, specifically to a method and apparatus for drying residual liquid in containers. The core of this method and apparatus involves "directly or indirectly heating the container body / inner liner to accelerate the evaporation of residual liquid." It is particularly suitable for drying residual liquid in conventionally used civilian / commercial containers (excluding large-capacity industrial-grade liquid storage containers), such as water cups, tableware, and sampling cups. Its application can be extended to various scenarios including container heating, heat preservation, temperature control, and moisture retention. The technical solution of this invention has the advantages of intelligence, convenience, high efficiency, low power consumption, and high adaptability, and its core logic based on heating control has good versatility and scalability. Background Technology

[0002] In daily life and work, residual liquid in various containers (such as cups, tableware, sampling cups, etc.) after use, if not dried in time, can easily breed bacteria, mold, and produce odors, affecting hygiene and user experience. Existing container drying methods mainly include natural air drying, manual wiping, drying with equipment such as disinfection cabinets, and combined drying methods such as "inverted gravity water control + hot air (such as PTC heating block + fan)". These methods have the following systemic defects: 1. Limited application scenarios and poor user experience: Natural air drying of containers is time-consuming and prone to mold and bacterial growth; manual wiping is cumbersome and poses a risk of cross-contamination; disinfection cabinets and other equipment are bulky and power-consuming, only suitable for batch processing, and cannot meet the immediate drying needs of individual containers, resulting in insufficient convenience for daily use and a poor user experience. 2. Deficiencies of existing combined drying equipment: Taking the "inverted gravity water control + hot air (such as PTC heating block + fan)" combined drying equipment (such as smart toothbrush holders) as an example, on the one hand, the container must be fixed upside down on a special bracket, and the inversion can easily cause residual liquid to remain at the mouth of the cup or in the gaps of the bracket, resulting in incomplete drying. In addition, the poor sealing of the air duct can easily introduce external dust, and the equipment itself is difficult to clean, which can easily cause secondary pollution and affect the hygiene experience. On the other hand, the continuous operation of the fan and the superimposed heating module result in high overall power consumption. Most of them rely on wired fixed power supply, which cannot achieve independent and convenient drying of individual containers, and cannot meet the daily usage habits of "use, place, and dry" for containers such as water cups. In addition, the continuous operation of the fan during the drying process generates noise, which affects the user experience. The fixed bracket design further limits the use scenarios. 3. Imbalance between drying efficiency and power consumption control: Existing drying technologies (such as hot air drying and fixed power heating) cannot detect and dynamically match the amount of residual liquid in the container, resulting in the problem of "incomplete drying at low power and excessive power consumption at high power, which can easily damage the container". This leads to an imbalance between drying efficiency and power consumption control. When there is a small amount of residual liquid, overheating leads to energy waste, and high-temperature drying can easily damage container materials with limited heat resistance, such as silicone. When there is a large amount of residual liquid, there is the problem of incomplete drying. 4. Insufficient adaptability and safety: Most existing products are designed for specific categories, specific materials (such as stainless steel) or specific structures (such as split containers), which cannot cover container scenarios with multiple categories, materials and structures. In addition, they lack precise temperature control, which can easily damage containers due to overheating and pose safety hazards. 5. Low level of intelligence and lack of convenience: Most existing solutions rely on manual triggering and lack an automatic triggering drying mechanism. They cannot achieve automatic start drying when the container is placed, resulting in poor operation convenience and difficulty in meeting the user habit and convenience needs of placing the container anywhere after daily use. This invention provides a method and apparatus for drying residual liquid in containers that can cover multiple scenarios, categories, materials, and structural forms, and features low power consumption, high adaptability, high security, strong scalability, and intelligent convenience, thereby solving the aforementioned systemic defects of the prior art. Summary of the Invention

[0003] (a) Purpose of the invention

[0004] The core objective of this invention is to overcome the aforementioned systemic defects of the prior art and provide a method and apparatus for drying residual liquid in containers. Through the core drying logic of "directly or indirectly heating the container body / inner liner to accelerate the evaporation of residual liquid", the residual liquid is dried by rapid and efficient evaporation. Furthermore, through a differentiated intelligent drying process using low-power mode, high-power mode, or a combination of high and low power consumption, a balance between power consumption control and drying efficiency is achieved. This invention is a highly adaptable, safe, intelligent, and convenient drying method and apparatus. Based on this, the present invention also aims to achieve the following derivative objectives: 1. The drying method and apparatus are constructed with an automatic triggering mechanism as the core and a manual triggering mechanism as an option, which improves the intelligence and convenience of user operation; 2. The container device supports multiple product categories, multiple container materials (metal / non-metal), multiple container capacity specifications, and multiple container structure forms (with or without lid, integrated or separate, with or without base / stand), etc., and has wide adaptability and versatility, covering multiple application scenarios such as daily portability, home, office, and outdoor. 3. The container device may be optionally configured with additional functional modules, such as an optional sterilization module to further improve hygiene, or an optional human-computer interaction module to adapt to different user needs; the optional additional functional modules do not affect the core drying logic of the present invention; 4. This invention provides three mature and mass-producible implementation schemes to support industrialization. The heating control core logic of this invention based on the container residual liquid drying method has good versatility and can be extended to scenarios such as container heating, heat preservation, constant temperature, and moisture retention, thereby enhancing the reuse value of the technical solution.

[0005] (II) Technical Solution

[0006] The core technical solution of this invention revolves around the drying of residual liquid in containers. It uses "direct or indirect heating of the container body / inner liner to accelerate the evaporation of residual liquid" as the core drying logic, constructing a differentiated drying process with a low-power mode as the core, a high-power mode as an option, and a combination of high and low power modes, achieving a precise balance between drying efficiency and power consumption control. The preferred low-power mode drying process is: automatic triggering + triple residual liquid quantity judgment + low-power drying process (high-power heating + low-power heat preservation (two stages) + intelligent shutdown / total duration shutdown). The preferred high-power mode drying process is: automatic triggering + residual liquid quantity judgment based on preset parameters + high-power drying process (high-power heating + low-power heat preservation (one stage) + intelligent shutdown / total duration shutdown). The container device supports two heating methods: "direct heating and indirect heating of the container body / inner liner," and can be configured with heating auxiliary structures and container auxiliary structures to further improve thermal efficiency and evaporation efficiency. The container device includes, but is not limited to, a trigger module, a heating device, a detection module, a control module, a power supply module, and optional additional function modules (such as...). The container is a carrier for containing substances, including different specifications or capacities, materials, and structural forms. Container materials include metal and non-metal materials, with non-metallic materials including silicone, plastic, glass, ceramic, wood, and other suitable non-metallic materials. Container structures include those with or without lids, with or without bases / supports, integrated or split designs, and other suitable structural forms, adapting to multiple product categories and scenarios. The container device can be configured with, but is not limited to, heating auxiliary structures and container auxiliary structures, and additional functional modules (such as sterilization modules and human-computer interaction modules), without affecting the core drying logic of this invention. Furthermore, the core heating control logic of the container residual liquid drying method of this invention can be extended to scenarios such as container heating, heat preservation, constant temperature, and moisture retention, without changing the core structure; only relevant parameters need to be adjusted. It is not limited to container categories, materials, or structural forms, and has advantages such as strong technical versatility, strong scalability, and high reusability. To clearly illustrate the core drying logic of this invention, a detailed description of each module is provided below in conjunction with the accompanying drawings:

[0007] 1. Overview of Drying Methods (corresponding to...) Figure 2 (Overview of drying methods) A method for drying residual liquid in a container uses "direct or indirect heating of the container body / inner liner, and conducting heat to the residual liquid to accelerate its evaporation, thereby achieving container drying" as its core drying logic. An overview diagram of the drying method is shown below. Figure 2 As shown, the details are as follows: (1) The control module receives the start signal sent by the trigger module (S201 receives the start signal): The trigger signal includes manual triggering (D202b) or automatic triggering (D202a). This invention takes automatic triggering without human intervention as the core, and manual triggering is optional. Manual triggering has a higher priority than automatic triggering. The triggering type of automatic triggering (D202a) is classified based on the triggering logic, including but not limited to the following: ① Attitude / Motion Detection Triggers: These are triggered by detection elements that can determine the container's attitude (such as upright or tilted) and user actions (such as picking up or moving the container), including but not limited to ball switches, gravity sensors, tilt sensors, and gyroscopes. ② Non-contact sensing triggering: This is achieved through sensing elements that can detect the status of containers and users without physical contact, including but not limited to optical sensors, vision sensors, etc. ③ Human-computer interaction triggers: These are triggered by user-initiated commands, including but not limited to voice control, remote control via APP, gesture operation, button operation, NFC, etc. ④ Environment / Status-Related Triggers: These are triggered indirectly by detecting environmental or status parameters inside or outside the container, including direct parameters (such as temperature and humidity values) and indirect parameters (such as indirectly feeding back the residual liquid status by "collecting the voltage peak value when the heating element is powered off"). ⑤ Structural linkage triggers: triggered by physical contact or structural linkage between the container and its supporting components (such as lids, bases / supports, etc.), such as when the base / support detects that the container has been placed in place, or when the lid is closed on the container; The triggering element and installation location of the D202a automatic trigger are not limited. They can be adapted to multiple dimensions such as container properties (specifications, materials, structural form), residual liquid state parameters, and usage environment and scenario. One or more triggering elements can be used in combination. (2) The control module independently or in conjunction with the detection module (if any) performs the D202 residual liquid quantity value judgment and controls the heating device to perform the drying process (including the M203 low power mode (see details)). Figure 4 ) and M204 high-power mode (see details) Figure 3 (Two types); the M203 low-power mode drying process is the core, suitable for application scenarios with high power consumption requirements, especially portable scenarios; the M204 high-power mode drying process is optional; suitable for application scenarios with high drying efficiency requirements and low power consumption requirements, especially desktop and other fixed scenarios; high and low power drying processes can also be used in combination (see the following embodiment two for details). (3) During or after the drying process, additional functional modules may be added (S205 (optional) Additional functional modules (such as sterilization modules), the types of sterilization modules include but are not limited to UV sterilization (preferred) and ozone sterilization, etc.; the additional functional modules are optional and do not affect the core drying processing logic of the present invention; (4) In the drying process, it is preferable to preset a safe temperature threshold and monitor it in real time. If the temperature touches the safe temperature threshold, the machine will automatically stop or the heating power will be reduced to ensure safety and controllability.

[0008] 2. Container and heating device structure (corresponding) Figure 1 (Schematic diagram of container and heating device) A method and apparatus for drying residual liquid in a container, wherein the heating device of the container is the core technical feature of the core drying process logic of the present invention, and its core function is to directly or indirectly heat the container body / inner liner, through an internal heating device disposed on the container body / inner liner, or an external heating device separate from the container body / inner liner; the following is in conjunction with the appendix. Figure 1 The optimal solution is explained in detail below: (1) The heating device of the container mainly includes core components and optional components. The core components are the necessary structural features to achieve the drying function, and the optional components are additional structural features adapted to multiple scenarios; as follows: ①Core components: 101 Container body / inner liner, 102 Heating element; ② Optional components: 131 Cover (optional), 132 Base / Standard (optional); (2) The core component of the heating device is the 102 heating element (core technical feature), which heats the container body / inner liner. The heating method includes direct heating and indirect heating. The specific type, heating power, shape, size, and installation position of the 102 heating element are not limited. It can be adapted to the container properties (specifications, materials, structural form), residual liquid state parameters, and usage environment and scenario. Specifically, as follows: ①The specific types of the heating element 102 include, but are not limited to, the following: a. Integrated integral heating: The resistor is directly integrated into the container body / inner liner through a process (such as the side wall or bottom of the container inner liner), realizing the integration of the heating resistor with the container body / inner liner, and achieving optimal heat conduction efficiency; b. Thin-film heating: including but not limited to PI heating elements (balancing thinness and stability, with fast thermal response), PIA heating film, carbon fiber heating film, silicone heating film, ceramic heating elements, PET heating film, etc., which can be installed by surface bonding or embedding. c. Traditional block / wire heating: heating elements, heating wires, heating tubes, PTC heating, etc.; ② Direct heating method: The installation position of the 102 heating element (flexible selection, mutually exclusive substitution) includes, but is not limited to, the following: a. Preferred location: such as Figure 1 As shown, a PI heating element is preferably used to adhere to the bottom of the 101 container body / inner liner, or the concave annular area of ​​the bottom, to match the shape of the container, as described in Embodiment 1 and Embodiment 2 below; b. Optional alternative locations: such as installation at Figure 1 The 132 base / bracket (optional) is shown; the 132 base / bracket is an optional component, and the heating element installed therein is an optional alternative, which only needs to be installed in one position (different positions are mutually exclusive alternative implementations, and do not need to be installed at the same time); ③ Indirect heating method: The installation position of the heating element 102 (flexible selection, mutually exclusive substitution) includes, but is not limited to, the following: a.106 Indirect heating source (optional): such as installing a PTC heating element inside the container, with the assistance of a fan, to generate hot air that surrounds the 101 container body / inner liner to achieve indirect heating; b. The silicone tableware of the following embodiment three adopts the design of an independent functional lid. The independent functional lid has a built-in heating element 102 (preferably a ceramic heating plate) and is equipped with a heating auxiliary structure such as a fan 105 (optional) to improve air circulation efficiency. Indirect heating is achieved by heating the air between the lid 131 (optional) and the container body / inner liner 101. (3) The heating device may be optionally configured with auxiliary structures to improve thermal efficiency and evaporation efficiency; the auxiliary structures include, but are not limited to, 122 heating auxiliary structure (optional), 121 container auxiliary structure (optional), 103 heat insulation layer (optional), 105 fan (optional), etc. Regardless of whether the auxiliary structures are used, they are all equivalent measures of the core drying process logic of "heating the container to accelerate the evaporation of residual liquid"; the auxiliary structures include two types: passive auxiliary structures and active auxiliary structures, both of which are optional optimization measures. The preferred scheme is as follows: ① Passive auxiliary structure: mainly used to optimize heat conduction and reduce losses. a. Heat-conducting and flow-guiding auxiliary structures: For example, the auxiliary structure of container 121 (optional) adopts the following preferred design: the bottom of the container liner is designed to be concave in the center or annular concave shape, and the sidewall is designed to be inclined or to use hydrophobic textures, coatings, etc. to guide the residual liquid to gather in the bottom area of ​​the liner. The gathering area can be equipped with capillary effect micro-textures (such as dot / strip / mesh, etc.) to guide the gathered residual liquid to spread quickly to form a water film, thereby increasing the area and improving thermal efficiency and evaporation efficiency; For example, the heating auxiliary structure of 122 (optional) adopts the following preferred design: such as the three-layer composite structure design of the heating device, the specific measures are: firstly, use a high thermal conductivity material (such as copper, aluminum, etc.) plate to stamp a heat-conducting sheet similar to the shape of the lower part of the container (including the bottom), and then install the heat-conducting sheet on the back of the heating sheet at the bottom of the container to form a three-layer composite structure of "container body / liner + heating sheet + heat-conducting sheet". The heat-conducting sheet can effectively conduct the heat on the back of the heating sheet to the side of the container body / liner, thereby improving thermal efficiency and reducing heat loss; b. Thermal insulation auxiliary structure: such as the 103 thermal insulation layer, which can be applied to a double-layer composite container structure of "inner liner + outer shell"; ② Active auxiliary structure: including but not limited to 105 fan (optional), turbine, air pump, etc., with dual functions of auxiliary heating and auxiliary evaporation: as in the independent functional cover design of Embodiment 3 below, the 102 heating element, combined with the active auxiliary structure such as 105 fan (optional), achieves indirect heating and improves thermal efficiency, and can accelerate the discharge of water vapor in the container during the drying stage to improve evaporation efficiency, especially suitable for container structures and scenarios with lids; (4) The heating power adjustment logic of the 102 heating element can be adapted and adjusted in multiple dimensions based on the optimization goal of improving thermal efficiency and evaporation efficiency; all power adjustments and fixed parameter settings based on the following dimensions are equivalent measures, and the specific dimensions include but are not limited to the following: ① Container dimension: Adjustments are made based on the thermal conductivity of the container material and the structural design. Low thermal conductivity + insufficient structural optimization is suitable for higher initial power, while high thermal conductivity + adequate structural optimization is suitable for lower initial power. ② Residual liquid dimension: If the residual liquid state parameter is higher than the preset threshold, the container body / inner liner is heated with higher power; if it is lower than the preset threshold, the container body / inner liner is heated with lower power. ③ Environmental scenario dimension: When the ambient temperature is below 5℃ (preferred), the initial heating power should be increased appropriately; when the ambient temperature is above 35℃ (preferred), the initial power should be reduced appropriately, and the ambient temperature should be used to help improve efficiency. (5) The installation and heating methods of the 102 heating element (including both direct heating and indirect heating) and optional structural optimization schemes, including but not limited to the following: ① Direct heating of container body / inner liner + structural optimization: The heating element is directly attached to / embedded in the container body / inner liner for direct heating, and is combined with a structural optimization scheme; the structural optimization scheme includes, but is not limited to, 121 container auxiliary structure (optional), 122 heating auxiliary structure (optional), 103 heat insulation layer (optional), etc.; the structural optimization scheme is an optional configuration, and its core is the drying process logic of "heating the container body / inner liner to accelerate the evaporation of residual liquid"; ② Direct heating with matching base / stand + structural optimization: The heating element is installed inside the container base / stand, and the container is directly heated after the container is detected to be placed in the base / stand. ③ Indirect heating of the matching cover + structural optimization: As shown in the following embodiment three, it is achieved by using a heating element (preferably a ceramic heating plate) set in an independent functional cover, combined with an optional heating auxiliary structure (such as a fan).

[0009] 3. Low-power mode drying process logic (corresponding to) Figure 4 (Low-power mode drying logic diagram) A method for drying residual liquid in a container, wherein the M203 low-power mode drying process is the core of the invention, is suitable for application scenarios with high power consumption requirements, especially for portable applications, and the core logic of its drying process is as follows: Figure 4 As shown; to further clarify the drying process of M203 low-power mode, the specific threshold parameters below are all based on actual measured data. The measured object is the integrated smart cup of Embodiment 1 below, whose general structure is as follows. Figure 5 As shown, the capacity of this integrated smart cup is preferably 300mL. It adopts a double-layer design with a plastic heat-insulating outer shell and a stainless steel inner liner. The bottom of the inner liner features a concave annular shape with capillary micro-texture on the inside and a PI annular heating element (preferred) attached to the outside. The structure is an independent, integrated design. The entire drying process requires no inverting of the cup, no traditional fan assistance, no noise, and no manual intervention. It is particularly suitable for portable applications, achieving a seamless "use-as-you-go, place-and-dry-as-you-go" intelligent experience. The actual measured data is based on a real indoor environment with a temperature of 17℃ and no air convection. The specific drying process in the M203 low-power mode is as follows: (1) In the M203 low-power mode drying process, the control module independently or in conjunction with the detection module executes the following steps: ①S402 receives the start signal (manual or automatic triggering, with automatic triggering as the core and manual triggering as optional, with manual triggering having higher priority than automatic triggering), enters the S403 low-power mode drying process, executes M401 triple residual liquid quantity judgment (preferably triple judgment), completes D405 judgment based on the detected residual liquid quantity value and comparison with a preset threshold, preferably the residual liquid quantity value is divided into three levels, as follows: a. If the residual liquid volume of D405a is ≤ the preset threshold (e.g., 1 mL is preferred), then execute S408 to start the drying process; b. If the preset threshold of D405b (e.g., 1 mL preferred) < the amount of residual liquid ≤ the upper limit of pretreatment (e.g., 10 mL preferred), then execute S406 to start the pretreatment process until the amount of residual liquid ≤ the preset threshold (e.g., 1 mL preferred) and then execute S408 to start the drying process. c. If the residual liquid volume of D405c is greater than the pretreatment upper limit (e.g., 10 mL preferred), then execute S407 to prevent startup and issue a prompt; ②S408 starts the drying process and executes the M411 low-power drying process (preferably using S409 high-power heating stage + S410 first-stage heat preservation stage + S413 second-stage heat preservation stage). The drying process adds a D412 interrupt mechanism. As in the following embodiment, the attitude / action type automatic trigger is preferred. The triggering element is preferably two independent ball switches. When the user moves the cup during the drying process, the ball switches detect that the cup is tilted or upright and reaches the preset threshold range, and then automatically trigger the interrupt mechanism. Alternatively, a manual trigger interrupt mechanism can be added. The manual trigger has a higher priority than the automatic trigger. a. If no interruption is detected during the drying process, the S414 (optional) sterilization process is executed in the drying process, followed by the S415 intelligent shutdown / total duration shutdown, and finally the S499 process ends. b. When an interruption is detected during the drying process, if the state after the interruption matches the state before the interruption, the original process continues, and then the S415 intelligent shutdown / total duration shutdown is executed, and finally the S499 process ends; if the state after the interruption does not match the state before the interruption, the process restarts and enters the M401 triple residual liquid quantity judgment step until the S499 process ends. ③ An additional functional module S414 (optional) sterilization process can be added during or after the execution of the M411 low-power drying process; (2) The total time limit for the above M401 triple residual liquid quantity judgment steps is 13 minutes (preferred), which consists of the second judgment 10 minutes (preferred) limit + the third judgment 3 minutes (preferred) limit; the specific steps are as follows: ① First-level judgment: Preferred automatic triggering is achieved using attitude / motion detection. The triggering element includes, but is not limited to, ball switches, gravity sensors, tilt sensors, gyroscopes, and other detection elements capable of determining the container's attitude. Preferred is the use of ball switches (e.g., in Example 1, using two independent ball switches). The independent operation of the two ball switches provides reliability and a simplified algorithm and circuit design. The specific logic is as follows: When... Figure 5 The 551a ball switch 01 detected a container tilt angle of ±30° (determining that the user had used the container, generating a potential drying demand), and subsequently returned to ±10° (this value is determined by...). Figure 5 If the ball switch 02 detects within the range of the 551b and the device remains stationary for a preset time (preferably 1 minute), it is determined that there is a need for initial drying. ② Second judgment: Preferably, the current temperature of the container is collected by a temperature sensor to obtain the ambient reference temperature, and at the same time, it is determined whether the reference temperature is within the preset normal temperature range (e.g., 5℃ to 35℃ is preferred); if the reference temperature is >35℃ or <5℃, the temperature waiting stage is entered, and the temperature is continuously collected in real time. The total duration of this stage is up to 10 minutes (preferably); if the temperature recovers to the 5℃ to 35℃ range within 10 minutes, the subsequent judgment is performed; if the temperature still does not reach the standard within 10 minutes, the machine is stopped. ③ Third-level judgment: The total duration is capped at 3 minutes (preferred). The specific steps are as follows: Control the PI heating element (preferred) to heat for a period of time (40 to 80 seconds, preferably 60 seconds). The temperature sensor, based on the ambient temperature collected in the second-level judgment above and the temperature change value during this heating stage, compares it with the threshold parameter to determine the amount of residual liquid in the container. It supports adding one or more detection elements to achieve more accurate judgment. These detection elements include, but are not limited to, reused heating element two-pole electrical connection, capacitive sensor, electrode sensor, humidity sensor, etc. "Reuse heating element two-pole electrical connection" is preferred. The specific method is: during the initial stage of heating using the reused heating element, collect the peak voltage of the heating element's two poles at the instant heating stops (i.e., power is cut off), compare it with the threshold parameter, and further determine the amount of residual liquid. The third-level judgment, based on the above measured physical object, provides experimental data, specifically referring to the "Appendix". Figure 9 The measured data is shown in the table below; (3) The preset threshold (e.g., 1 mL preferred) and the pretreatment upper limit (e.g., 10 mL preferred) of the D405 based on the detected residual liquid volume are both based on the above-mentioned actual test sample; the actual test sample has a natural residual water volume between 0.3 mL and 0.8 mL after multiple simulated uses by multiple people. Based on certain design redundancy requirements, the preset threshold is preferably 1 mL. (4) The pretreatment methods of the above D406 pretreatment process include, but are not limited to, atomization, micro-air drying, heating concentration, ultrasonic dehydration, etc. The core objective is to pretreat the amount of residual liquid in the container to a preset threshold. Regardless of the pretreatment method used, they are all equivalent measures. (5) In the above-mentioned preferred M411 low-power drying process, in the high-power heating stage of S409, the heating power ranges from 3W to 6W, preferably 4.5W, and the heating time ranges from 1 minute to 5 minutes, preferably 3 minutes. The core objective is to quickly raise the temperature of the residual liquid accumulation area in the container; in the first-stage heat preservation stage of S410, the heating power ranges from 0.5W to 1.5W, preferably 1W, and the heating time ranges from 3 minutes to 7 minutes, preferably 5 minutes; in the second-stage heat preservation stage of S413, the heating power ranges from 0.3W to 0.8W, preferably 0.5W, and the heating time ranges from 5 minutes to 25 minutes, preferably 15 minutes. The core objective is to maintain the temperature by continuously heating with low power, thereby efficiently evaporating the residual liquid; based on the above-mentioned actual test, ultra-low total power consumption is achieved, and experimental data, including heating power, heating time, etc., are provided. For details, please refer to "Appendix". Figure 8 The measured data is shown in the table below; (6) The logic of the above S415 intelligent shutdown / total duration shutdown is as follows: ① Intelligent shutdown: During the drying process, a temperature sensor monitors the temperature in real time. When the temperature reaches the preset drying temperature threshold (preferably 45℃), the machine automatically shuts down. To further consolidate the drying effect, low-power heating can be activated again 30 seconds (preferably) after automatic shutdown. The heating power is preferably the first-level heat preservation power of S410, until the temperature reaches the preset drying temperature threshold (preferably 45℃) again, at which point the machine will shut down completely automatically. The number of times the preset drying temperature threshold (preferably 45℃) is reached ranges from 1 to 3 times, preferably 2 times. In this step, you can optionally refer to the "third judgment" above, where when the temperature reaches the preset drying temperature threshold (preferably 45℃), the peak voltage of the heating element at the moment of power failure is collected and compared with the preset threshold to further determine whether the preset standard for intelligent shutdown has been met. ② Total Duration Shutdown: The preset total duration limit for the drying process is 30 minutes (preferred). If, during the entire drying process, the temperature sensor does not detect a temperature reaching the preset drying temperature threshold (e.g., 45℃ is preferred) within the total duration limit, then a total duration shutdown will be executed after the total duration is reached. If there is a small amount of residual liquid in the container after drying, it can be quickly dried again under the residual temperature of the container and the ambient temperature. The total duration shutdown logic is to ensure that the power consumption limit for a single cycle is controllable, thereby making the battery life controllable. (7) The above optional S414 sterilization process is an optional additional function module. UV sterilization is preferred. The triggering logic is preferably as follows: when the drying process performs intelligent shutdown, that is, before the upper limit of the total duration, the sterilization process is automatically executed after the intelligent shutdown; when the drying process performs a total duration shutdown, the sterilization process is automatically triggered at the last period of the total duration and is completed synchronously with the drying process after the total duration is reached; it can also be adjusted according to user needs (such as manual triggering by the user). All of these are equivalent measures. Its core is to work in coordination with the drying process without increasing the core power consumption of the equipment; the duration of UV sterilization can be set to 5 minutes (preferred), and the total time of the drying process and the optional sterilization process is controlled within the upper limit of the total duration to ensure that the overall process is efficient and controllable; the above UV sterilization is only the preferred sterilization method. Other sterilization methods are equivalent measures. The installation position of the sterilization component includes, but is not limited to, the container itself or the accessories set separately by the container (such as lids, brackets, etc.).

[0010] 4. High-power mode drying process logic (corresponding to) Figure 3 (High-power mode drying logic diagram) A method for drying residual liquid in a container, wherein the M204 high-power mode drying process is suitable for application scenarios with high drying efficiency requirements and low power consumption requirements, especially suitable for fixed scenarios such as desktops. An optional detection module can be configured to compare preset parameter thresholds. The detection module can be implemented using one or more composite detection elements, including but not limited to temperature sensors and humidity sensors. The logic diagram of the M204 high-power mode is attached. Figure 3 As shown, the details are as follows: (1) The M204 high-power mode drying process is performed as follows: ①S301 receives the start signal (manual trigger or automatic trigger, automatic trigger is the core, manual trigger is optional, manual trigger has higher priority than automatic trigger), enters the S302 high power mode drying process, and executes M304 to judge the residual liquid value based on preset parameters based on manual trigger or automatic trigger (preferred) (can be paired with D303 (optional) detection module). The residual liquid value can be divided into one level or multiple levels, preferably three levels, namely D305a small residual liquid level, D305b medium residual liquid level, and D305c large residual liquid level; ②S306 Start the drying process (according to preset parameters), execute the M311 high-power drying process (preferably using "high-power heating + low-power insulation (level 1)", which can be paired with the D307 (optional) detection module); the drying process adds a D312 interrupt mechanism. For example, in the high-power drying process of the "pure base power supply" scenario in the following embodiment 2, the drying process is automatically triggered when the user places the cup on the base after use, and the interrupt mechanism is automatically triggered when the user picks up the cup and removes it from the base. For example, in the silicone tableware of the following embodiment 3, the drying process is automatically triggered when the independent functional cover is closed on the tableware body, and the interrupt mechanism is automatically triggered when the independent functional cover is opened. A manual trigger interrupt mechanism can also be added, with manual triggering having higher priority than automatic triggering. If an interruption is detected during the high-power drying process, the machine stops and executes S308 to issue a prompt signal, and finally the process ends in S399. If no interruption is detected during the drying process, the sterilization process is executed in S314 (optional), then the intelligent shutdown / total duration shutdown is executed in S305, and finally the process ends in S399. ③The above S314 (optional) sterilization process is an optional additional function module. Referring to the optional S414 (optional) sterilization process in the M203 low power mode, based on preset parameters, it supports triggering during the drying process or after the drying process is completed. (2) The D303 (optional) detection module and the D307 (optional) detection module preferably reuse one or more of the same detection elements. For example, in Embodiment 2 below, the "safety temperature control temperature sensor" is preferably reused, that is, a single temperature sensor is shared throughout the entire container. In Embodiment 3 below, in addition to the temperature sensor, a humidity sensor is added to the detection element. The installation position of the detection element is not limited. The type and installation position of the detection element are necessary conditions and equivalent measures for the optional detection modules. The two optional detection modules differ in their core functions, as follows: ①D303 (optional) detection module: The core function is the initial judgment and classification of residual liquid volume; the detection element is preferably a temperature sensor. Referring to the low-power drying process, the judgment is based on the ambient temperature at the start of the drying process and the temperature change value during the initial heating time of 60 seconds (preferred). Compared with the low-power mode drying process, the accuracy of residual liquid volume judgment can be greatly reduced in the high-power mode, such as the expansion of the ambient temperature classification range, which can simplify the collection of experimental data and reduce the number of threshold parameters. ②D307 (optional) detection module: Its core function is to dynamically detect the state parameters of residual liquid in the container during the drying process, providing data support for intelligent shutdown / total duration shutdown; (3) The above-mentioned M311 high-power drying process is preferably executed according to preset parameters, and preferably adopts the heating logic of "high power heating + low power heat preservation (level 1)"; the preset parameters can be adapted according to the container attributes (specifications, materials, structural forms), residual liquid state parameters, and usage environment and scenario from multiple dimensions, and are not specifically limited, including but not limited to the following: ① Fixed parameters: such as preset fixed heating power and heating time, as well as preset drying standard parameters, etc., and intelligent shutdown / shutdown after execution is completed; ② Variable parameters: such as preset variable dynamic heating power and heating time, change logic, drying standard parameters, etc., based on residual liquid volume state parameters, and intelligent shutdown / total duration shutdown after execution; (4) The core of the above-mentioned S315 intelligent shutdown / total duration shutdown is the preset drying standard and shutdown logic and other execution parameters; the total duration shutdown logic refers to the low power mode, and the drying standard involved in intelligent shutdown is described in conjunction with the following embodiments 2 and 3, as follows: ① In the "pure base power supply" scenario of Example 2, it is preferable to use temperature threshold cycling, and intelligently stop after reaching the preset number of cycles, that is, preset upper temperature threshold and lower temperature threshold. When the temperature reaches the upper temperature, switch to heat preservation power or stop the machine. When the temperature drops to the lower limit, restore the heating power. The cycle is executed until the preset number of cycles are reached and then intelligently stop the machine. ② Example 3 is based on an indirect heating design with an independent functional cover. It preferably uses multiple preset dimensions such as temperature sensor and humidity sensor. Please refer to Example 3 below for details.

[0012] (III) Beneficial Effects

[0013] The container residual liquid drying method and apparatus disclosed in this invention address the core pain points of existing container drying technologies, such as "imbalance between power consumption and efficiency, limited applicable scenarios, cumbersome operation, insufficient safety protection, and poor scalability." The core drying logic is "directly or indirectly heating the container body / inner liner to accelerate the evaporation of residual liquid." It employs a low-power drying process as the core, with a high-power drying process as an option, or a combination of both. Through multi-dimensional innovative design, it achieves a dual breakthrough in technology and market value. The core beneficial effects are as follows.

[0014] 1. Core Technology Value (1) Precise core positioning, deep balance between drying efficiency and energy consumption control ①Low power mode: The control module determines the residual liquid volume based on one or more detection modules (preferably using the first level of automatic attitude / action triggering + the second level of ambient temperature + the third level of residual liquid volume determination), and executes a low power drying process (preferably using high power heating + low power heat preservation (two stages) + intelligent shutdown / total duration shutdown). The container heating device can be configured with auxiliary structures (such as optional container auxiliary structure, optional heating auxiliary structure) to further improve thermal efficiency and evaporation efficiency, achieving intelligent, efficient and ultra-low power consumption of the entire drying process. It is suitable for use scenarios with high power consumption requirements, especially for everyday portable use scenarios. ② High power consumption mode: The control module judges the amount of residual liquid based on preset parameters and executes a high power consumption drying process (preferably using high power heating + low power heat preservation (level 1) + intelligent shutdown / total duration shutdown), which is suitable for use scenarios where containers have high requirements for drying efficiency and low requirements for power consumption, especially suitable for use scenarios on fixed desktops; ③ Combined use of high and low power consumption: As shown in Example 2 below, the split container drying can be used in two scenarios: "pure base power supply (high power consumption)" and "portable with battery (low power consumption)". (2) Wide adaptability ① Containers: Suitable for containers of different specifications or capacities, regardless of material or structural form; ② Product Category: Open design that adapts to all product categories, such as water cups, tableware, sampling cups, etc. ③Scenario: The low-power mode is suitable for application scenarios with high power consumption requirements, while the high-power mode is suitable for application scenarios with high drying efficiency requirements and low power consumption requirements, covering a wide range of scenarios; (3) Intelligent and convenient, taking into account both hygiene and safety ① Intelligent and Convenient (Core User Experience): Automatic triggering enables intelligent and convenient operation without manual intervention. Through automatic triggering methods including but not limited to posture / action triggering and structural linkage triggering, it achieves a seamless intelligent experience of "use, place, and dry immediately" for users. An interruption mechanism is added to the drying process. If the user moves the container during the drying process, it will automatically pause / switch / restart. Manual triggering can be added, and manual triggering has higher priority than automatic triggering. A human-computer interaction module can be configured to adapt to user-defined needs. ② High hygiene: Additional functional modules (such as a sterilization module) can be optionally configured. UV sterilization is preferred, with a sterilization rate of ≥99%, meeting food-grade requirements. The sterilization process is carried out simultaneously after the drying process or in the final stage of the drying process, ensuring efficient completion of the drying and sterilization processes within the total time. It can be combined with a sealed and waterproof container structure design to enable the container to be fully washed, achieving a "zero maintenance" experience for users and further improving hygiene. ③ High safety: The temperature is monitored in real time by a temperature sensor added to the container. When the temperature reaches the preset safe temperature threshold (preferably 60℃), the machine will automatically stop or reduce the heating power to avoid the risk of high temperature damage to the container and burns to users, making it safe and reliable. (4) It has strong scalability and outstanding product value and industrialization potential. ① High scalability: The core drying technology logic of this invention, which is to "directly or indirectly heat the container body / inner liner to accelerate the evaporation of residual liquid", can be extended to other containers for heating, heat preservation, constant temperature and moisturizing in various scenarios, such as constant temperature storage of cosmetic products such as cosmetic cushions, heat preservation of various tableware such as lunch boxes and baby food bowls, constant temperature and heat preservation of various beverages, and heating, constant temperature and moisturizing of daily necessities such as wet wipes. No need to change the core structure, only the relevant parameters need to be adjusted to achieve the corresponding functions. No need to bind to specific materials, and it is suitable for multiple scenarios such as daily portability, home, office and outdoor. ② Industrialization potential: The following three examples provide a complete design solution that can be mass-produced. The core structure is complete, the algorithm is simplified, and the security and reliability are high. It can be flexibly adapted to the target scenario, and its market adaptability and commercial value are significant.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] (I) Example 1: Integrated Smart Cup A method and apparatus for drying residual liquid in a container, applied to an integrated smart cup, such as... Figure 5 As shown, this corresponds to the integrated drying device described in claims 10 and 11.

[0028] 1. Structural details The integrated smart cup in this embodiment adopts a double-layer composite structure design (outer shell (511 upper outer shell + 512 lower outer shell, both made of heat-insulating and anti-scalding plastic material) + inner liner (501 container body / inner liner, made of stainless steel), mainly including a trigger module, heating device, detection module, control module, power supply module, and optional additional function modules (such as optional sterilization module, optional human-computer interaction module, etc.); the preferred capacity of the integrated smart cup is 300mL, and it can be equipped with a 531 lid (optional) to meet dust protection requirements; the specific structural details are as follows: (1) Heating device: The heating device is the core component of the integrated smart cup in this embodiment. It uses direct heating to heat the container body / inner liner and mainly includes 501 container body / inner liner, 502 heating element, and 521 container auxiliary structure (optional), as follows: ①501 Container Body / Inner Liner: Made of stainless steel, roughly cylindrical in shape, with optional 521 container auxiliary structure; The preferred embodiment of the 521 container auxiliary structure is: the bottom of the container inner liner is provided with an annular concave area (preferably filled with capillary effect microtexture), which guides the residual liquid to gather in the bottom annular concave area and quickly spread to form a thin film, thereby increasing the area and improving thermal efficiency and evaporation efficiency; ②502 heating element: preferably a PI annular heating element, which is the core component of the heating device; it is attached to the outer side of the annular concave area at the bottom of the container liner to directly heat the container liner; the heating power of the 502 heating element can be dynamically adjusted between 0.2W and 6W to adapt to the drying process; (2) Triggering module: Preferred automatic triggering based on posture / action. The triggering element preferably uses two independent ball switches (551a ball switch 01, detecting ±30° tilt; 551b ball switch 02, detecting ±10° tilt). The installation position is preferably integrated on the built-in control circuit board where the 582 control module is located, which is used to detect the container posture to realize automatic triggering. Based on the independence of the two ball switches, the algorithm and circuit design can be simplified, and the reliability is improved. (3) Detection module: The detection module consists of a 552 temperature sensor and a 553 detection element (optional), as detailed below: ①552 Temperature Sensor: Preferably an NTC thermistor is used, preferably attached to the outer side of the bottom of the container liner, avoiding the PI ring heating element at the bottom of the container liner and the optional UV sterilization lamp (if present) set in the middle of the bottom of the container liner, to detect the temperature of the liner and provide data support for judging the state of residual liquid and intelligent shutdown. ②553 Detection Element (Optional): Its core function is to work in conjunction with the 552 temperature sensor to further accurately detect the residual liquid state parameters. It preferably uses a reusable heating element two-pole circuit connection. Its working principle is: it collects the voltage peak value at the moment the heating element is powered off and compares it with a preset threshold. See details... Figure 5 Schematic diagram of the 553 detection element (reusable heating element poles); (4) Control module: The 582 control module preferably adopts a single-chip microcomputer, and is preferably integrated with two ball switches and a 561 wireless charging receiver module on a built-in control circuit board. The control circuit board is provided with ports for electrical connection to the 502 heating element, 552 temperature sensor, 553 detection element (optional), 581 battery, 503 sterilization module (optional) and optional human-machine interaction module (if any), and integrates full-link control logic such as "trigger, start / stop, switch, execute, and judge". (5) Power supply module: Built-in 581 battery, preferably with a capacity of 5000mAh, suitable for daily portable scenarios; and a 561 wireless charging receiver module is integrated on the above-mentioned built-in control circuit board for battery charging and replenishment. (6) Optional module: 503 sterilization module (optional) preferably uses a UV sterilization lamp located in the middle of the bottom of the inner liner to sterilize the container and the items inside the container, with a sterilization rate of ≥99%, which meets the food-grade safety standards; an optional human-computer interaction module can also be added to meet the user's customized needs.

[0029] 2. Work Process The drying process in this embodiment is designed for mass production and uses "direct heating of the container body / inner liner to accelerate the evaporation of residual liquid" as the core intelligent drying logic. It preferably adopts the M203 low-power mode drying process: the control module independently or collaboratively performs a triple residual liquid quantity judgment based on the detection module, enters and executes the low-power drying process, and can optionally configure additional function modules (such as a sterilization process). An interrupt mechanism is added to the drying process; the specific steps are as follows: (1) Based on the triple residual liquid volume judgment of the detection module (preferably the first level of automatic triggering of posture / action + the second level of ambient temperature + the third level of residual liquid volume judgment): the specific processing logic and execution steps refer to the above-mentioned M203 low power mode drying process; the residual liquid volume threshold is preferably 1mL, and the setting basis is: after multiple simulated user uses by multiple people, the natural residual liquid volume is usually 0.3mL to 0.8mL, and based on a certain design redundancy, it is determined to be preferably 1mL; this embodiment is only designed for a small amount of residual liquid ≤1mL; if the residual liquid volume is ≤1mL, the low power drying process is started directly; if the residual liquid volume is >1mL, the drying process is prohibited from starting, and the user is prompted by the indicator light; the details are as follows: ① First-level judgment (preferred posture / action type automatic trigger): After the user places the cup upright on the table for a period of time (preferred 1 minute) after using it, it will be automatically triggered. Specifically, two independent ball switches are preferred. When the user uses the cup, the ball switch 01 of 551a detects the tilt within ±30° to determine that the cup is in use. After use, when the cup is placed on the table, the ball switch 02 of 551b detects the tilt within ±10° to determine that the cup has been used and placed on the table. The combined signal of the two sends an automatic trigger command to the control module. No manual operation is required, realizing the intelligent start of the drying process as soon as it is used and placed on the table. ② Second judgment (ambient temperature): The 552 temperature sensor collects the current temperature of the container to obtain the ambient reference temperature, and at the same time determines whether the reference temperature is within the preset normal temperature range (such as 5℃ to 35℃ preferred); if the reference temperature is >35℃ or <5℃, it enters the temperature waiting stage and continuously collects the temperature in real time. The total duration of this stage is up to 10 minutes. If the temperature recovers to the 5℃ to 35℃ range within 10 minutes, the following steps continue to be executed. If the temperature still does not reach the standard within 10 minutes, the machine stops, the process is terminated, and a prompt is issued. ③ Third-level judgment (residual liquid volume judgment): The 582 control module controls the 502 heating element to initially heat the container for a period of time (range 40 to 80 seconds, preferably 60 seconds). The temperature sensor, based on the collected ambient temperature and the temperature change value during this initial heating period, compares it with preset parameters to determine whether the residual liquid volume in the container is ≤1mL. An optional 553 detection element (preferably a reusable heating element with two-pole electrical connection) can be configured. Its working logic is: to collect the peak voltage between the two poles of the 502 heating element (preferably a PI ring heating element) when the initial heating stops (i.e., at the moment of power failure), compare it with preset parameters, and further determine whether the residual liquid volume in the container is ≤1mL. See Appendix for details. Figure 9 The table showing the actual measured experimental data is provided. (2) The low-power drying process (preferred high-power heating + low-power heat preservation (two stages) + intelligent shutdown / total duration shutdown) achieves a single drying power consumption of 0.3Wh to 0.8Wh. See Appendix for details. Figure 8 The actual experimental data table shown is as follows: ① High-power heating: The heating power ranges from 3W to 6W, preferably 4.5W, and the heating time ranges from 1 minute to 5 minutes, preferably 3 minutes. The core objective is to rapidly heat the container to raise the temperature of the residual liquid accumulation area inside the container and bring it into the high-efficiency evaporation temperature range. ② Low-power heat preservation (two stages): The first stage heat preservation heating power ranges from 0.5W to 1.5W, preferably 1W, and the heat preservation time ranges from 3 minutes to 7 minutes, preferably 5 minutes; the second stage heat preservation heating power ranges from 0.3W to 0.8W, preferably 0.5W, and the heat preservation time ranges from 5 minutes to 25 minutes, preferably 15 minutes; the core objective is to maintain the temperature through continuous low-power heating, thereby accelerating the continuous and efficient evaporation of residual liquid and achieving a drying effect; ③ Intelligent shutdown: During the second-stage low-power heat preservation phase, the 552 temperature sensor dynamically detects the temperature. When the temperature reaches the preset drying temperature threshold (preferably 45℃), the machine automatically shuts down. To further consolidate the drying effect, after automatic shutdown (preferably 30 seconds), the first-stage heat preservation heating power (preferably 1W) can be restarted until the temperature reaches the preset drying temperature threshold again (preferably 45℃), at which point the machine will completely shut down intelligently. Alternatively, an optional 553 detection element (using the two poles of the heating element for electrical connection) can be configured to collect the peak voltage of the two poles of the 502 heating element (PI ring heating element) at the moment of power failure when the temperature reaches the preset drying temperature threshold (preferably 45℃). This peak voltage is compared with preset parameters to further determine whether the preset standard for intelligent shutdown has been met. In this embodiment, drying was completed at 45℃. ④ Total Duration Shutdown: The preset total duration of the drying process is capped at 30 minutes. If the 552 temperature sensor does not detect a temperature reaching the preset drying temperature threshold (e.g., 45℃ is preferred) during this period, the machine will be forcibly shut down after the total duration is reached. If there is a small amount of residual liquid in the container after drying, it can be quickly dried again under the residual temperature of the container and the ambient temperature. The total duration shutdown ensures that the power consumption limit for a single cycle is controllable, thus making the battery life controllable. (3) Optional sterilization process: The preferred sterilization process has a total duration of 5 minutes. The triggering logic is as follows: Referring to the M204 low-power drying mode, if the drying process ends through intelligent shutdown, it will be automatically triggered after intelligent shutdown. If the shutdown is due to the total duration, the sterilization process will be carried out synchronously with the final drying process. Manual triggering is supported, and manual triggering has a higher priority than automatic triggering. (4) Interruption mechanism: An interruption mechanism is added to the drying process. For example, when the user moves the cup during the drying process, it is automatically triggered by the ball switch. After the interruption is restored, the detection module starts detection. If the residual liquid state after restoration is the same as before the interruption, the original drying process is restored. If the residual liquid state after restoration is different from before the interruption, the drying process is restarted. (5) Safety temperature control: Based on the low power consumption mode drying process, the actual temperature of this embodiment is 45℃ after drying and shutdown. The maximum temperature does not exceed 50℃, which is lower than the preset safety temperature threshold (such as 60℃ preferred), so it is safe and reliable.

[0030] 3. Beneficial effects This embodiment of the integrated smart cup, while inheriting the overall beneficial effects, is tailored to the daily portable use scenario of a "single smart water cup," aligning with the user habit of "use it, put it away, and let it dry instantly," thus demonstrating unique technological and market value; specifically as follows: (1) Core value: It has achieved a breakthrough in the form of single-unit smart water cup drying, creating a brand-new sub-category of "single-unit smart water cup drying". This embodiment, through the deep integration of integrated structural design and low-power drying logic, creatively opens up a new subcategory of "independent intelligent drying for individual water cups," effectively solving the core pain points of existing technologies, as detailed below: ① Compared to traditional water cups: Traditional water cups require manual wiping to remove residual liquid after use (time-consuming, laborious, and prone to secondary contamination) or natural air drying (taking 4 to 8 hours, and in actual testing, bacteria start to grow after 1 hour, easily becoming moldy and producing odors). This embodiment automatically triggers the drying process through posture / action. After use, the user only needs to place the cup on the table to start and complete the drying process without manual intervention. The intelligent drying of residual liquid is completed in 30 minutes (preferred), which solves the problem of dampness, bacteria growth, and mold from the root, greatly improving hygiene. ② Compared with existing drying equipment such as smart toothbrush holders: Existing equipment relies on fixed brackets and adopts a combination of "inverted gravity water control + hot air drying" drying method, which poses a risk of cross-contamination due to shared brackets, the drying process is noisy, and it must be used in a fixed setting; This embodiment does not require inversion, does not require brackets, has no fan and is noiseless, and with an automatic triggering mechanism, it fits the user's habit of "placing the water cup anywhere and using it anytime", and is suitable for the portable use scenario of water cups; (2) Implementation of technical effects: a precise balance between low power consumption and user experience This embodiment employs an intelligent drying logic of "triple residual liquid volume judgment + low-power drying process" to achieve precise results for water cup usage scenarios: ① Automatic Triggering and Precise Drying Synergy: Through a three-step process of "automatic triggering based on posture / motion + ambient temperature + residual liquid volume judgment", the system automatically triggers and determines whether the residual liquid volume is ≤1mL of the preset threshold. This ensures that the drying process is only initiated when the cup is detected to be stably placed and the residual liquid volume is ≤1mL of the preset threshold, avoiding false triggering and improving intelligence and reliability. When the user moves the cup during the drying process, the posture / motion detection element will intelligently interrupt the process and automatically resume or restart the drying process after the cup is repositioned, achieving a truly "intelligent and seamless" user experience. ② Extreme power consumption control and long battery life: The power consumption of a single drying cycle is controlled between 0.3Wh and 0.8Wh. With a 5000mAh battery, the battery life is increased by 2 to 3 times (25+ cycles) under the premise that the total drying time is limited to 30 minutes. It eliminates the constraints of fixed stands and wired power supply, making it suitable for everyday portable scenarios for water bottles. ③ Safety and hygiene upgrades: When the measured temperature reaches 45℃, the residual liquid dries and the machine automatically shuts down. The maximum temperature does not exceed 50℃ to avoid overheating and damaging the container material. Optional UV sterilization function is available, with a sterilization time of 5 minutes and a sterilization rate of ≥99%, meeting food-grade safety standards. ④ "Zero maintenance" experience: Based on the independent one-piece design without a fan, the drying process is noiseless. Combined with the fully sealed structural design, it can be fully washed. Like a traditional non-smart water bottle, it has "zero maintenance" in daily use. (3) Expanding value: technology reuse and scenario extension The low-power intelligent drying core technology logic of this embodiment can be directly extended to scenarios such as container heating, heat preservation, constant temperature, and moisturizing. No changes are required to the core structure; only the relevant parameters need to be adjusted to achieve the corresponding functions. It does not need to be bound to a specific container material and is especially suitable for small, sealed containers, such as the constant temperature storage of cosmetic products like cosmetic cushions, and the heating, heat preservation, and moisturizing storage of daily necessities like wet wipes, further broadening the application scenarios and enhancing commercial value.

[0031] (II) Example 2: Split-type smart cup A method and apparatus for drying residual liquid in a container, applicable to a split-type smart cup (cup body + base / stand + optional lid), such as... Figure 6 As shown, this corresponds to the split-type drying device described in claims 10 and 12. The split-type smart cup in this second embodiment is an extension and expansion of the integrated smart cup in the first embodiment, demonstrating the application of the split structure in the scenario of drying residual liquid in a container. It preferably adopts a smart drying process that combines high and low power consumption. The high-power drying process is suitable for the "pure base-powered" scenario, and the low-power drying process is suitable for the "battery-powered portable" scenario, realizing the dual-scenario application of "daily portability + fixed desktop". This embodiment does not limit the power supply method of the cup body and the base / stand. Wireless power supply is preferred, but it can also be achieved through other power supply methods such as contact points. Different power supply methods are all equivalent measures.

Structural details The split-type smart cup in this second embodiment comprises three parts: "cup body (core functional carrier), base / stand (power supply / charging + structural linkage triggering), and lid (optional)". To clearly illustrate that this embodiment is adapted to both "pure base-powered (no battery + no attitude detection element)" and "portable with battery (with battery + attitude detection element)" scenarios, the following descriptions are based on the two scenarios: (1) "Pure base power supply" scenario: Suitable for application scenarios with high drying efficiency and low power consumption requirements, especially suitable for desktop fixed scenarios. ① Main body of the cup: This is the core functional carrier, employing a double-layer composite structure design (611 outer shell (heat-insulating and anti-scalding plastic material) + 601 container body / inner liner (stainless steel material)), with a preferred capacity of 400mL; details are as follows: a.601 Container Body / Inner Liner: Made of stainless steel, roughly cylindrical in shape, the inner liner does not require optional auxiliary structures and focuses on the core heating and drying function; b. 602 heating element: preferably a PI heating element, which is attached to the outer side of the bottom of the container liner to directly heat the container liner; the heating power of the 602 heating element can be dynamically adjusted between 0.5W and 10W to adapt to the drying process; c.622 Heating Auxiliary Structure (Optional): Preferably, a "three-layer composite structure of heating device" is adopted. Specifically, a heat-conducting sheet is stamped from a 0.5mm thick aluminum plate into a shape similar to the lower part of the container (including the bottom). The heat-conducting sheet is attached to the back of the PI heating sheet at the bottom of the container to form a three-layer composite structure of "container / inner liner + PI heating sheet + heat-conducting sheet". The heat-conducting sheet can effectively utilize the heat on the back of the PI heating sheet and conduct the heat to the side of the container body / inner liner, thereby improving thermal efficiency and reducing heat loss. d.652 Temperature Sensor: Preferably an NTC thermistor is used to detect the temperature of the container body / inner liner, providing data support for residual liquid status judgment, safe temperature threshold judgment, intelligent shutdown (drying standard setting), etc. e. Control Module: The 682 control module preferably uses a microcontroller and is preferably integrated with the 661 wireless charging receiver module on a built-in control circuit board; the control circuit board is provided with ports for electrical connection to the 602 heating element, 652 temperature sensor, etc., and integrates full-link control logic such as "trigger, start / stop, switching, execution, and judgment"; ② Base / Standard (Power Supply / Charging + Linkage Trigger) a.632 Base / Stand: Built-in 662 wireless charging transmitter module and 683 base control module, used to provide wireless power and charging for the cup, and equipped with a "structural linkage trigger element (preferred configuration for "pure base power supply" scenario)", which automatically triggers the start of the drying process when the cup is placed in place, and automatically triggers the stop of the drying process when the cup is removed from the base / stand. b.683 Base Control Module: Preferably, a single-chip microcomputer is used, preferably electrically connected to the 662 wireless charging transmitter module, structural linkage trigger element, etc., and preferably integrated on the base control circuit board to realize power supply adjustment, structural linkage trigger logic control, etc. (2) "Battery-enabled Portable" Scenario: Adapts to the use scenario where the cup body detaches from the base / stand and is portable independently. In this scenario, the cup body is based on the cup body in the "pure base-powered" scenario described above. It is preferably achieved by adding a 651 attitude detection element (preferably integrated into the built-in control circuit board within the cup body) and a 681 battery (optional). These two components are necessary for achieving the "battery-powered portability" scenario and are mutually compatible; details are as follows: a.651 Attitude Detection Element (Optional): Preferably a dual ball switch (detects ±30° tilt, ±10° upright), preferably integrated on the built-in control circuit board where the 682 control module is located, used to detect the container attitude and realize automatic triggering; b.681 Battery (optional): Preferred battery capacity 2500mAh, suitable for 10 short-term battery life uses, with 661 wireless charging receiver module for receiving charging from the base / stand; (3) 631 lid (optional): includes a built-in 671 fan (optional) and a 603 sterilization module (optional); the 603 sterilization module (optional) is used to improve hygiene; the 671 fan can improve air circulation efficiency and accelerate the discharge of water vapor during the drying process to improve drying efficiency.

[0033] 2. Work Process The split-type smart cup in this embodiment uses a smart drying process that combines high and low power consumption. The high-power drying process is suitable for the "purely base-powered" scenario, while the low-power drying process is suitable for the "battery-powered portable" scenario. The "purely base-powered" scenario has higher priority than the "battery-powered portable" scenario. That is, when the cup is placed on the base / stand, the high-power drying process under the "purely base-powered" scenario is used. When the cup is removed from the base, it automatically switches to the low-power drying process under the "battery-powered portable" scenario. The working process is described below according to the two scenarios: (1) Judgment of residual liquid volume Based on actual measurements and multiple simulations of user use of the container, the amount of naturally remaining liquid is typically between 0.5 mL and 1.2 mL. Based on a certain design redundancy, the preset threshold for the amount of remaining liquid is preferably 1.5 mL. ① Residual liquid quantity judgment in the "battery-enabled portable" scenario: The triple residual liquid quantity judgment of Example 1 is preferred. Only the third judgment needs to be adjusted in the triple residual liquid quantity judgment of Example 1. After adjustment, the third judgment of this example only requires a temperature sensor as a detection element, without the need for any other detection elements. The method is as follows: The control module first collects the ambient temperature through the 652 temperature sensor, and then controls the heating device to perform initial heating for 60 seconds (preferably). The residual liquid quantity is judged by comparing the temperature change during the initial heating period with the preset parameter threshold. If the residual liquid quantity is ≤ the preset threshold (preferably 1.5mL), the low-power drying process is started and executed. If the residual liquid quantity is > the preset threshold (preferably 1.5mL), the drying process is prohibited and a prompt signal is issued. ② Determining the residual liquid volume in the "pure base-powered" scenario: It is preferable to use the same method as in the "battery-powered portable" scenario; alternatively, the residual liquid volume determination based on preset parameters in the M204 high-power mode described in this invention can be used. For example, based on user experience, the residual liquid volume can be divided into two or more levels: a small amount (≤1.5mL) and a large amount (>1.5mL), and a differentiated high-power drying process can be selected. This embodiment only applies to the high-power drying process when the residual liquid volume is a small amount, that is, when the residual liquid volume is ≤ a preset threshold (preferably 1.5mL). (2) "Pure base power supply" scenario: preferred structure linkage trigger + high power drying process ①Automatic Trigger: The 632 base / support is equipped with a "structural linkage trigger element" (preferred configuration). When the cup is placed on the base / support and remains still for 1 minute (preferred), the high-power drying process is automatically triggered. ② High-power drying process The preferred heating process is high-power heating + low-power heat preservation (level 1) + intelligent shutdown / total duration shutdown: The heating power of the high-power heating stage ranges from 6W to 10W (preferably 8W). After heating to (preferably 50℃), it switches to the low-power heat preservation stage, where the heating power ranges from 1W to 5W (preferably 3W). After heating to (preferably 55℃), heating stops. Once the temperature returns to (preferably 50℃), the heating power of the low-power heat preservation stage (preferably 3W) is restarted. After the temperature returns to (preferably 55℃), heating stops. This heating logic based on temperature changes cycles 1 to 5 times (preferably 3 times) to trigger intelligent shutdown. The drying process has a preset total duration (preferably 15 minutes), which forces a total duration shutdown when the total duration is reached. An interruption mechanism is added to the drying process. When the user removes the cup from the base / support during the drying process, the structural linkage trigger element automatically triggers the interruption mechanism, terminating the drying process and issuing a prompt signal to remind the user. (3) "Portable with battery": Preferred posture / action triggering + low power drying process ①Automatic Trigger: When the cup body detaches from the base / support, the 651 attitude detection element (preferably a dual ball switch) detects a combination signal of "±30° tilt and ±10° upright", which automatically triggers the low-power drying process; ② Low-power drying process (preferred high-power heating + low-power insulation (two stages) + intelligent shutdown / total duration shutdown): The low-power drying process preferably adopts the same low-power drying process as in Embodiment 1 of the present invention, only requiring changes to the core parameters; specifically: the heating power of the high-power heating stage in this embodiment is preferably 6W, the heating power of the first low-power heat preservation stage is preferably 2W, and the heating power of the second low-power heat preservation stage is preferably 1W. Other parameters, including but not limited to heating time, temperature threshold, and total time, can preferably be kept the same as in Embodiment 1; an interruption mechanism is added to the drying process. When the user moves the cup during the drying process, the 651 attitude detection element automatically triggers the interruption mechanism, terminates the drying process, and issues a prompt signal to remind the user; (4) Sterilization and safety control ① The 603 sterilization module (optional) is built into the 631 cover (optional). It preferably uses UV sterilization with a sterilization rate of ≥99%, which meets food-grade safety standards. The total sterilization process is preferably 5 minutes. The triggering logic is as follows: if the drying process is based on intelligent shutdown, it will be automatically triggered after the drying process ends. If the drying process is based on the total time shutdown, the sterilization process will be automatically triggered in the last period of the drying process. After the total time is reached, the sterilization process and the drying process are completed synchronously. It supports adding manual triggering of the sterilization process, and manual triggering has a higher priority than automatic triggering. ②Safe temperature control: The 652 temperature sensor monitors the temperature throughout the process. If the temperature reaches (preferably 55℃) during the drying process, the machine will automatically stop. The actual measured temperature will not reach 60℃. The entire drying process is safe and controllable. In the "pure base power supply" scenario, it is preferable to place another temperature sensor inside the base / support to monitor the temperature of the base / support, so as to avoid the base / support from overheating when the power supply is heated or charging, thereby improving safety. (5) Power supply logic: When the structural linkage trigger element detects that the cup is placed on the base / stand, the high power consumption drying process under the "pure base power supply" scenario is adopted. During the execution of the high power consumption drying process, the base / stand simultaneously supplies power to heat the cup and charge the built-in battery. The built-in battery automatically stops charging when it is fully charged.

[0034] 3. Beneficial effects The split-type smart cup in this second embodiment is a specific implementation of the "split-type ready-to-use, ready-to-dry smart cup". It is an extension and expansion of the "integrated ready-to-use, ready-to-dry smart cup" in the first embodiment. It demonstrates the application of the split structure in the scenario of drying residual liquid in a container. Through the intelligent drying logic that combines high and low power consumption, it realizes the dual scenarios of "daily portability + fixed desktop", showing unique technical and market value, as detailed below: (1) Core technology value: echoing the overall logic and realizing dual verification of structure and technology. ① The split structure of this embodiment is effectively different from the integrated structure of Embodiment 1, which verifies that the core drying technology of the present invention is not limited to a single container structure form. It can flexibly adapt to different containers of "integrated / split type" according to the scenario, echoing the technical feature of "no limit to structural form" in the overall beneficial effect. ② The intelligent drying process using a combination of high and low power consumption in this embodiment verifies that the core drying logic of the present invention can operate effectively under different strategies of "low power consumption / high power consumption", echoing the drying method of "combining high and low power consumption" in the overall beneficial effect; ③ Compared with existing heating containers: such as insulated cup mats, insulated cups, kettles and other existing heating container products all aim to "keep / heat the liquid inside the cup", with the core being to maintain or increase the liquid temperature; the core of this embodiment is "drying the residual liquid inside the container", with the core drying logic of "heating the container body / inner liner to accelerate the evaporation of residual liquid", which is fundamentally different from existing products in terms of technical purpose, and effectively solves the pain point of "residual liquid in the container causing dampness, bacteria growth and odor"; (2) Implementation of technical effects: Dual-mode adaptation, balancing drying efficiency with power consumption / battery life ① Dual-scenario adaptation, balancing drying efficiency and battery life: In the "pure base-powered" scenario, a high-power drying logic is adopted to achieve rapid drying in 15 minutes, which is suitable for usage scenarios with high drying efficiency requirements and low power consumption requirements; in the "portable with battery" scenario, a low-power drying logic is adopted, which is suitable for usage scenarios with high power consumption requirements. With a single drying time of 30 minutes, the battery life can reach more than 10 times with a 2500mAh battery, which is especially suitable for portable scenarios; ②Structural linkage triggering for a smart and convenient experience: The "battery-powered portable" scenario uses posture / action-based automatic triggering, which is suitable for "daily portable" use scenarios; the "base-powered" scenario uses structural linkage automatic triggering, which is suitable for "fixed desktop" use; achieving a smart and seamless user experience of "use, place, and dry instantly" in both scenarios; the use of posture / action-based triggering and structural linkage triggering echoes the adaptability to multiple automatic triggering types in the claims of this invention; (3) Expanding value: technology reuse and scenario extension The intelligent drying core technology logic used in the high and low power consumption combination of this embodiment can be directly extended to other scenarios such as heating, heat preservation, constant temperature, and humidification of containers. No changes are required to the core structure; only the relevant parameters need to be adjusted to achieve the corresponding functions. It does not need to be bound to a specific container material, and is especially suitable for constant temperature and heat preservation scenarios of beverage / food containers, further broadening the application scenarios and enhancing commercial value.

[0035] (III) Example 3: Silicone tableware (single tableware + independent functional lid) A method and apparatus for drying residual liquid in containers, applicable to silicone tableware (single tableware + independent functional lid + optional base), such as... Figure 7 As shown, this corresponds to the silicone tableware drying device described in claims 10 and 13. The silicone tableware in this third embodiment is an extension and expansion of the first two embodiments. Through the design of an independent functional lid adapted to a single silicone tableware, it demonstrates the core drying logic of "indirectly heating the container body / inner liner to accelerate the evaporation of residual liquid". Using a single silicone tableware as a carrier, it is designed to adapt to the poor thermal conductivity and limited heat resistance of silicone material, adapting to the container residual liquid drying needs of open tableware. It forms a multi-dimensional technical complement with the previous two embodiments in terms of container material (silicone material in this embodiment, stainless steel material in the previous two embodiments), category (tableware in this embodiment, water cup in the previous two embodiments), and heating method (indirect heating in this embodiment, direct heating in the previous two embodiments). This third embodiment only describes the intelligent drying method logic of silicone tableware. Specific parameters, including but not limited to heating power, heating time, temperature threshold, humidity threshold, etc., are not limited and can be adapted according to the container attributes (specifications, material, structural form), residual liquid state parameters, and usage environment and scenario.

[0036] 1. Structural details The silicone tableware in Example 3 consists of three parts: 701 container body (tableware body), 731 independent functional lid (core independent functional module), and 732 base / stand (optional), as detailed below: (1) 731 Independent Functional Cover (Core Independent Functional Module): The 731 independent functional cover includes a heating device, a 752 temperature sensor (preferred), a 753 humidity sensor (preferred), a 781 battery, a 782 control circuit board, a 703 sterilization module (optional), etc.; it has a built-in "structural linkage trigger element" to realize automatic triggering after the independent functional cover is closed. A human-machine interaction module can be optionally configured to meet user customization needs; the details are as follows: ① Heating device (core functional module) The heating device is a core functional module, consisting of a 702 heating element (the core component of the heating device) and a 771 heating auxiliary structure (preferably). Its core function is to "indirectly heat the container body / inner liner to accelerate the evaporation of residual liquid"; specifically as follows: a.702 Heating element (core component of heating device): preferably a ceramic heating plate is used, which is located inside the 731 independent functional cover near the container cavity as a heat source and is used in conjunction with the 771 heating auxiliary structure (preferably) to heat the air in the space between the 731 independent functional cover and the 701 container body, thereby indirectly heating the container body / inner liner. b.771 Heating Auxiliary Structure (Preferred): The core function of the heating auxiliary structure is to improve the air circulation efficiency within the container, and to work with the heating element to achieve efficient indirect heating of the container body / inner liner, thereby solving the problem of insufficient heat transfer efficiency due to the poor thermal conductivity of air under simple heating. The heating auxiliary structure may be configured with, but is not limited to, a container sealing structure and an air intake / exhaust structure (such as a one-way valve) to achieve directional air circulation and airflow discharge, further improving thermal efficiency and evaporation efficiency. The heating auxiliary structure includes active auxiliary structures (including but not limited to power components such as fans, turbines, and air pumps, whose core is to actively drive airflow) and passive auxiliary structures (including but not limited to the design of a non-powered circulation channel with thermosiphon effect). ② Control Module: The control module preferably uses a microcontroller and is preferably integrated on a 782 control circuit board. The 782 control circuit board provides electrical connections for the control module, heating device, 752 temperature sensor (preferred), 753 humidity sensor (preferred), 781 battery, and 703 sterilization module (optional). It integrates full-link control logic such as "trigger, start / stop, switching, execution, and judgment". A power supply / charging module (such as a wireless charging receiver module, Type-C interface, etc.) can be added. Manual buttons can be added to realize manual triggering, function switching, parameter adjustment and setting, etc. A human-machine interaction module can be optionally configured to adapt to user-defined needs. ③752 Temperature Sensor (Preferred): NTC thermistor is preferred, used to collect ambient temperature and real-time temperature during the drying process, providing data support for dynamic adaptation and adjustment of parameters such as heating power; ④753 Humidity Sensor (Preferred): A capacitive humidity sensor is preferred, used to detect the air humidity inside the container, providing data support for determining the dryness of the residual liquid inside the container and intelligent shutdown, etc. ⑤781 Battery: Battery capacity is not limited and can be adapted to multiple dimensions such as container attributes (specifications, materials, and structural forms), battery life requirements, and usage environment and scenarios. ⑥703 Sterilization Module (Optional): This is an optional additional function module. It is preferred to use UV sterilization with a sterilization rate of ≥99%, which meets food-grade safety standards. It is preferred to be integrated into the 782 control circuit board inside the 731 independent function cover. (2) 701 Container body (tableware body) The 701 container body is made of food-grade silicone and is in the shape of open tableware such as bowls and plates. It serves as a carrier for containing substances and a target carrier for drying residual liquids. It is only assembled with the 731 independent functional lid to realize indirect heating of the container. The 701 container body does not need to be equipped with any detection elements or any electronic components that are charged or require power. It is suitable for the high-frequency cleaning needs of tableware containers and can be soaked in water for full washing. (3) 732 base / stand (optional) The 732 base (optional) serves only as a support base for placing the main body of the 701 container. It can be integrated with a wireless charging module as needed to provide external power supply / charging for the 731 independent functional cover. It can also be equipped with basic structures such as anti-slip features.

[0037] 2. Work Process This third embodiment addresses the poor thermal conductivity and limited heat resistance of silicone material through an adaptive design. It preferably employs the M204 high-power drying process of this invention, combined with actual mass production design. Through a split, independent functional lid structure, and using an indirect heating method for the container, it achieves "low-temperature rapid drying" of individual silicone tableware. The drying process preferably adopts a "structural linkage trigger + high-power drying process" approach, as detailed below: (1) Temperature detection controls safety + humidity detection determines dryness In the preferred embodiments of the first two above, the entire drying process is mainly based on temperature thresholds to determine the state of residual liquid, set and determine drying standards, and implement safety control based on temperature thresholds. In this embodiment, based on an indirect heating method, a humidity threshold is preferably used to determine the state of residual liquid and set and determine drying standards. The temperature threshold is used as an auxiliary measure for drying, and temperature detection is used for safety control. ① Drying judgment logic: setting drying standards A capacitive humidity sensor is preferably used to continuously collect the air humidity inside the container during the drying process. This data is then combined with the ambient humidity (i.e., the air humidity detected when the drying process starts) to determine the drying status. When the following preferred combination of conditions is met simultaneously, it is determined that the residual liquid inside the container has dried, and an automatic intelligent shutdown is triggered, as follows: a. The difference between the relative humidity inside the container and the relative humidity of the environment is ≤ ±5%RH; b. The relative humidity inside the container is ≤30%RH; c. The above humidity level remains stable for 3 minutes (preferred). ② Determining the amount of residual liquid: a. Judgment based on the amount of residual liquid detected The preferred solution is as follows: In the initial stage of the drying process, the control module controls the heating device to perform indirect heating in conjunction with the preferred heating auxiliary structure. When the temperature sensor detects that the temperature reaches the preset temperature threshold (e.g., preferably 40°C), the preset threshold is compared with the three dimensions of "humidity change, temperature change, and time consumption" in the container in the above stage, and the residual liquid volume judgment based on detection is performed. b. Judgment of residual liquid volume based on preset parameters: It is preferable to judge the residual liquid volume based on the user's experience and divide it into one or more levels; This example 3 is based on the above drying standards and does not require precise judgment of the residual liquid amount. When implementing the product, it is only necessary to simulate the actual measured object and preset the residual liquid amount threshold based on a certain design redundancy to ensure that the above drying standards can be met within the preset total time (preferably 15 minutes) and achieve the drying of residual liquid within the residual liquid amount threshold range; the residual liquid amount threshold is equivalent to the upper limit of the amount of residual liquid to be dried within the total time. (3) Drying process: Optimal structure linkage automatic triggering + high power consumption drying process ① Start the drying process Automatic triggering is preferably achieved by using structural linkage triggering elements, that is, the drying process is automatically started after the user closes the independent functional cover. The drying process can also be started manually by manual button triggering or human-machine interaction module triggering. ② High-power drying process (preferred high-power heating + low-power heat preservation (first stage) + intelligent shutdown / total duration shutdown) The preferred method is the high-power drying process (high-power heating + low-power heat preservation (level 1) + intelligent shutdown / total duration shutdown) in the "pure base power supply" scenario of Embodiment 2 described above. Specifically, the control module, based on a preset threshold heating power, uses high-power heating during the high-power heating phase to quickly raise the temperature to the preset temperature threshold (preferably 40°C). Then, it switches to the low-power heat preservation phase, using low-power continuous heating to maintain the temperature and promote continuous evaporation. When the temperature reaches 45°C (preferably), heating stops. Once the temperature returns to 40°C, low-power heating is restarted until the temperature reaches 45°C (preferably) again, at which point heating stops. This process is based on the aforementioned temperature range. The process is executed cyclically, with no limit on the number of cycles. During execution, a humidity sensor monitors the humidity inside the container in real time, and a temperature sensor monitors the temperature inside the container in real time, providing data support for dynamic power adjustment. The machine intelligently stops when the humidity threshold reaches the preset drying standard. The drying process has a preset total time for stopping (preferably 15 minutes). Once the total time is reached, the machine will be forcibly stopped regardless of whether the humidity judgment condition is met, to avoid continuous operation under abnormal conditions. An interruption mechanism is added to the drying process. When the user opens or closes the lid during the drying process, the structural linkage trigger element automatically triggers an interruption, terminating the drying process and issuing a prompt signal to remind the user. A manual interruption mechanism can also be added. (4) Hygiene and Safety ①Optional additional function modules can be configured, with UV sterilization preferred and sterilization time preferred to be 5 minutes. It is triggered during or after the drying process, and the drying process and sterilization process work together to further improve hygiene; ② The temperature sensor monitors the internal air temperature in real time and controls the heating temperature within the safe temperature range suitable for the silicone material, preventing the silicone container from deforming or aging due to excessive temperature, thus achieving safe temperature control protection.

[0038] 3. Beneficial effects The silicone tableware in this third embodiment is an extension and expansion of the first two embodiments. It adopts an independent functional lid design adapted to a single open tableware. Through an "indirect heating of the container body / inner liner" heating method, it achieves the drying of residual liquid in the container. This "indirect heating of the container body / inner liner" heating method effectively distinguishes it from the "direct heating" of the first two embodiments, verifying the core drying logic of this invention (direct or indirect heating of the container body / inner liner to accelerate the evaporation of residual liquid). This third embodiment uses a single silicone tableware as a carrier, adapting its design to the material characteristics of silicone, such as "poor thermal conductivity and limited heat resistance," and the scenario characteristics of "open tableware easily leaving residue and requiring frequent cleaning." Building upon the advantages of the core drying logic, intelligent control, and safety protection of the first two embodiments, it specifically implements different heating methods, container types, container materials, container structures, and intelligent shutdown logic (drying standards), demonstrating unique technological and market value, as detailed below: (1) Core value: Echoing the overall logic and adapting to tableware scenarios ① The universal design, which echoes the overall design, verifies the broad applicability of this invention. This third embodiment adopts a container split structure design with an independent functional lid and a heating method of "indirect heating container", which is effectively different from the first two embodiments. It further verifies that the core drying technology of the present invention has wide applicability and realizes the universal design goal of not being limited by heating method, container structure, container type, or container material. ②Based on the design of an independent functional lid, the container body / inner liner can be fully washed without electricity, adapting to the characteristics and scenarios of tableware. In response to the characteristics of open tableware that requires frequent soaking and washing and is easily exposed to water, this third embodiment integrates all electrical components into an independent functional cover. The container body / inner liner is completely free of electricity, enabling full-body washing and soaking cleaning, thus eliminating safety hazards such as water ingress during cleaning, short circuits, and leakage from the structural source, and greatly improving the safety and reliability of use. The independent functional cover combined with indirect heating is the preferred structure for achieving heating function in open tableware containers. ③ Specifically addresses the drying challenges of silicone tableware, achieving a balance between low-temperature rapid drying and material protection. Existing silicone tableware lacks dedicated drying equipment and relies heavily on general high-temperature equipment such as sterilizers for batch drying. High-temperature environments can easily cause silicone material deformation and aging, and individual tableware cannot be dried instantly, resulting in poor portability for daily use. This third embodiment adopts a technical solution of "indirect heating + low-temperature control + high-power rapid drying," ideally completing the rapid drying of a single silicone tableware in 15 minutes. The indirect heating method avoids direct contact between the heating element and the container body, while closed-loop temperature control strictly maintains the safe temperature range for silicone, preventing localized overheating and high-temperature damage. The heating is gentle and uniform, suitable for the heat-insulating and fragile characteristics of silicone, as well as the open structure of tableware, achieving a new experience of "individual tableware, independent instant drying, and low-temperature safety," forming a fundamental technical difference from traditional high-temperature equipment. (2) Technical effects: intelligent and convenient, efficient drying, hygienic and safe. ①Structural linkage is automatically triggered, realizing and continuing the intelligent and convenient experience of "use, put away, and dry" globally; This embodiment three uses a structural linkage automatic triggering method. The drying process can be automatically started when the user puts the independent functional lid into place with the tableware container. ② Precise drying determination + multiple safety protections ensure reliable operation without hidden dangers. This third embodiment adopts a processing logic of "humidity detection to determine dryness + temperature detection to control safety" to avoid ineffective heating and overheating; based on temperature closed-loop control and total duration fallback mechanism, multiple safety protections are formed to prevent continuous heating under abnormal operating conditions; coupled with optional sterilization function (preferably UV sterilization), the drying process and sterilization process are carried out in tandem to further improve the hygiene of use; ③ Use humidity detection to determine dryness, enriching the methods for determining dryness. This embodiment three achieves dryness determination through humidity detection, further enriching the dryness determination method of the present invention, and verifying that dryness determination is only an auxiliary measure, which can be flexibly adapted according to container properties (such as material, structural form, etc.) and usage scenarios. The present invention still takes "direct or indirect heating of the container body / inner liner to accelerate the evaporation of residual liquid" as the core drying processing logic. (3) Expanding value: The modular design has strong versatility and significant advantages in industrialization. ① The structure and technology are highly versatile and adaptable to various materials and scenarios. Based on the independent functional lid of this embodiment, an external modular design is adopted, which does not require modification of the container body or binding to specific materials. It is primarily compatible with silicone open tableware, and can also be extended to similar tableware made of other materials such as stainless steel and food-grade plastic. The core technical features of this embodiment, such as indirect heating, low-temperature temperature control, humidity determination, and independent functional lid design, do not require modification of the core structure. Only the relevant parameters need to be adjusted to adapt to various materials, open structures, and container drying scenarios that require frequent washing, making the technology highly reusable. ② Diverse application scenarios and significant industrialization potential The core technologies of this embodiment three, such as indirect heating and independent functional lid design, do not require modification of the core structure. Only the relevant parameters need to be adjusted to realize the functions. They can be extended to various tableware / food containers, such as lunch boxes and baby food boxes, for heating and heat preservation, as well as daily necessities such as wet wipes for heating, constant temperature, and moisturizing, further broadening the application scenarios and enhancing commercial value and industrialization potential.

A method for drying residual liquid in a container according to claims 1 and 2, characterized in that, The low-power mode drying process is suitable for application scenarios with high power consumption requirements, especially for portable scenarios. The execution steps are as follows: (1) The control module receives the start signal sent by the trigger module and enters the low-power mode drying process; (2) The control module independently or in conjunction with the detection module collects the state parameters of the residual liquid in the container through one or more judgments, compares them with the preset threshold parameters, and divides the residual liquid amount into one or more levels, as follows: ① When performing a triple residual liquid quantity determination, the following steps can be taken: a. First judgment: After automatic triggering, the container posture (e.g., whether the container is returned to a horizontal position after use?) or placement position (e.g., whether the container is returned to the fixed base / support after use? whether the lid is properly closed after use?) are judged to meet the preconditions for starting the drying process; if they are met, the second judgment is executed; if they are not met, the process is terminated and a prompt signal is issued. b. Second judgment: Determine whether the container ambient temperature or initial temperature meets the preset temperature range of the drying process; if it meets the temperature range, execute the third judgment; if it does not meet the temperature range, enter the temperature waiting period; if it meets the temperature range within the preset waiting period, execute the third judgment; if it still does not meet the temperature range, terminate and issue a prompt signal. c. Third-level judgment: By combining the temperature change value during the initial heating stage with the ambient temperature or initial temperature, it is determined whether the residual liquid volume meets the drying requirements. It supports adding one or more detection elements to perform multi-dimensional judgments. If the requirements are met, the drying process is started; if not, it is terminated and a prompt signal is issued. ② If the residual liquid volume is divided into three levels, the details are as follows: a. For small quantities (residual liquid amount ≤ preset threshold): the control module directly executes the low-power drying process; b. When the medium volume setting is used (preset threshold < residual liquid volume ≤ pretreatment upper limit): the control module first executes the residual liquid pretreatment process. The core of the pretreatment process is to reduce the residual liquid volume in the container from the medium volume setting to the small volume setting. After reaching the small volume setting threshold, the low power drying process is then executed. c. At high volume (residual liquid volume > pretreatment upper limit): the control module prohibits the drying process and issues a warning signal; (3) The control module controls the heating device to perform a low-power drying process, and adopts the heating treatment logic of "high power heating + low power heat preservation (at least two stages) + intelligent shutdown / total duration shutdown".

(2) An interruption mechanism can be preset in the drying process. When the detection module detects an interruption, the control module compares the threshold parameter and executes at least one of the following: terminate the drying process, continue the drying process, or restart the drying process. (3) Intelligent shutdown / total duration shutdown: The total duration and drying standard are preset in the drying process; If the preset drying standard is detected before the total time is reached, the machine will intelligently shut down to reduce total power consumption. If the preset drying standard is not detected after the total time is reached, the machine will be stopped after the total time is reached to ensure that the total power consumption is controllable. The small amount of liquid remaining in the container can be dried naturally using the residual heat. (4) During or after the drying process, additional functional modules, such as a sterilization module, can be configured. The sterilization module is of at least one type, such as UV sterilization or ozone sterilization, and is installed on the container body / inner liner or its separate accessories. The accessories include at least one type, such as a lid or a base / support. The sterilization function supports automatic or manual triggering.

If the total time is reached, the sterilization process and the final stage of the drying process are synchronized and completed synchronously after the total time is reached. (5) A safe temperature threshold can be preset in the drying process.
