Abstract
Description
Technical Field
[0001] This invention relates to the field of infant clinical care and home care technology, specifically to an intelligent temperature-controlled infant bathing and protective care device. Background Technology
[0002] Infant care is a systematic process encompassing health monitoring, daily cleaning, and infant massage, among other aspects. Infant bathing is a core component, directly impacting an infant's skin health and safety. This is especially true for newborns and young infants, whose neck muscles are not fully developed, their thermoregulation is weak, and they lack self-protection awareness, placing extremely high demands on the safety and comfort of the bathing process. In infant bathing, household folding bathtubs, medical newborn bathing carts, and multi-functional bathing tables have become mainstream products, such as the Rikang RK-X1003-3 temperature-sensitive bathtub, the Babycare reclining folding bathtub, and the Xuzhou Medi MD-2013B medical mobile bathing cart.
[0003] Current infant bathing procedures generally rely on manual operation and experience-based judgment when filling the tub: While adding water, healthcare workers must continuously monitor the infant to prevent them from slipping or bumping against the tub's edge, repeatedly checking the water temperature and level with their hands or a thermometer, and manually turning off the water supply. During this process, water level control depends entirely on manual estimation. Precisely controlling the 3-5cm safe water level for newborns and the 5-8cm suitable water level for younger infants is difficult. Too high a water level can cause the infant to choke, while too low a level doesn't provide sufficient support, increasing the difficulty of holding them up. More importantly, healthcare workers must simultaneously monitor the infant and adjust parameters during the water filling process, occupying their hands with numerous repetitive movements. This significantly increases the workload and poses safety hazards due to distraction. For example, when adjusting the water flow, the infant may tip over or choke if no one is there to support them.
[0004] The core pain points of existing technologies can be summarized as follows: 1. Insufficient water level control precision: Manual estimation cannot accurately match the safe water level threshold for infants of different ages, which can easily lead to choking or difficulty in supporting the infant.
[0005] 2. Combined workload and safety risks: Nursing staff need to perform multiple tasks such as caregiving, temperature measurement, and water preparation at the same time, and the resulting distraction directly leads to a decrease in the safety of infant bathing.
[0006] 3. Poor water temperature stability: Lacking a dynamic constant temperature compensation mechanism, the water temperature is prone to sudden changes during bathing due to heat loss or the addition of water, increasing the risk of the baby catching a cold.
[0007] Therefore, this invention proposes an intelligent temperature-controlled baby bathing and protective care device to systematically solve the above-mentioned technical pain points. Summary of the Invention
[0008] To address the aforementioned issues, this invention provides an intelligent temperature-controlled infant bathing protection and care device, which enables precise and intelligent regulation of water temperature and level during infant bathing. This reduces the complexity of preparatory work for medical personnel, thereby minimizing safety hazards such as choking and tipping caused by manual operation, and ensuring the safety and comfort of newborns and young infants during bathing.
[0009] To achieve the above objectives, the technical solution of the present invention is as follows: A smart temperature-controlled baby bathing and protective care device includes a main control display panel, a faucet, a bathing platform, and a bathing tub. The bathing tub is located at the top of the bathing platform. The main control display panel and the faucet are both embedded in the top of the bathing platform. The bathing platform is equipped with a closed-loop temperature-controlled water supply system for supplying water to the faucet and heating the water. The closed-loop temperature-controlled water supply system is electrically connected to the main control display panel. A drain outlet is located at the bottom of the bathing tub. A liquid level monitoring and calibration component is located at the top of the bathing platform for setting a preset liquid level value and detecting the liquid level in the bathing tub. The liquid level monitoring and calibration component is electrically connected to the main control display panel. The main control display panel is used to automatically stop the closed-loop temperature-controlled water supply system from supplying water to the faucet when the liquid level monitoring and calibration component detects that the water level in the bathing tub meets the preset liquid level value.
[0010] The technical principle of the above solution is as follows: The operator sets the target water temperature through the main control display panel, and simultaneously adjusts the preset target water level for infants of different ages through the liquid level component. The target water level is simultaneously recorded on the main control display panel, forming a dual-parameter control benchmark. After water supply begins, the main control display panel sends a start command to the closed-loop temperature-controlled water supply system. The closed-loop temperature-controlled water supply system then connects to the water source and heats the water. Once the water temperature reaches the preset value, it automatically supplies constant-temperature hot water to the faucet, continuously injecting hot water into the bathing tub. During this process, when the liquid level monitoring and calibration component collects the liquid level data in the bathing tub and dynamically feeds the detection signal back to the main control display panel, the main control display panel immediately sends a stop command to the closed-loop temperature-controlled water supply system. The closed-loop temperature-controlled water supply system then stops supplying water to the faucet, achieving automated and precise control of the water injection process. After the infant bathing is completed, the wastewater in the bathing tub can be discharged uniformly through the bottom drain, completing the closed-loop operation of the entire bathing process.
[0011] The above solution offers the following advantages: Through the coordinated control of a closed-loop temperature-controlled water supply system and a level monitoring and calibration component, this solution achieves automated and precise regulation of the water temperature and level for infant bathing. This effectively solves the problems of large errors in water level estimation and cumbersome water temperature detection in traditional manual water filling methods. It accurately matches the safe water level requirements of infants at different stages, further reducing the risk of choking due to excessively high water levels and the difficulty of supporting the infant when the water level is too low. Simultaneously, the automated water supply shutdown mechanism reduces repetitive operations for caregivers, allowing them to focus on infant care and reducing safety hazards such as tipping over and bumps caused by distraction. This further enhances the safety, comfort, and ease of operation of infant bathing care.
[0012] Furthermore, the liquid level monitoring and calibration component includes a connected static pressure chamber and a height adjustment screw. The connected static pressure chamber is located inside the shower stall, and the height adjustment screw is threadedly connected to the shower stall. The bottom end of the height adjustment screw extends into the connected static pressure chamber and is fixedly connected to a floating force-bearing piston. The floating force-bearing piston slides in cooperation with the inner wall of the connected static pressure chamber. A water guiding channel is provided inside the shower stall, and the two ends of the water guiding channel are respectively connected to the bottom end of the connected static pressure chamber and the bottom of the shower tub. A pressure sensor is fixedly connected to the bottom of the floating force piston, and a laser rangefinder is fixedly connected to the top of the floating force piston. Both the laser rangefinder and the pressure sensor are electrically connected to the main control display panel.
[0013] Beneficial Effects: The liquid level monitoring and calibration components of this solution utilize the principle of communicating vessels. The water-conducting connecting channel forms a connected structure between the bath tub and the communicating static pressure chamber, ensuring that the liquid level in the bath tub remains consistent with the liquid level in the communicating static pressure chamber. This eliminates the need to directly install detection components inside the bath tub, avoiding the risk of scratches caused by contact between the detection element and the baby's skin. Furthermore, compared to directly detecting the liquid level, the method of determining the water level by detecting the liquid pressure on the floating piston using a pressure sensor effectively avoids interference from the baby's movements and water fluctuations during bathing. The detection data is more stable and accurate, preventing misjudgments due to instantaneous fluctuations in the liquid level.
[0014] Furthermore, the main control display panel is configured as follows: Initialization phase: The initial distance data between the floating force piston and the top of the connected static pressure chamber is collected by the laser rangefinder, and the preset target water level value in the bathing tub is calibrated based on the initial distance data; Water supply phase: Real-time reception of water pressure data in the connected static pressure chamber collected by pressure sensor. When the pressure data exceeds the preset threshold, an automatic stop water supply command is output to control the closed-loop temperature control water supply system to cut off the water supply path to the faucet.
[0015] Beneficial Effects: This solution uses a laser rangefinder to collect the initial distance of the floating force piston and calibrate the target water level, accurately matching the differentiated water level needs of newborns and young infants, enabling personalized water level presets. Simultaneously, using pressure data detected by a pressure sensor as the trigger condition for water supply shutdown effectively avoids interference from water fluctuations and the addition of bath products on detection accuracy compared to direct liquid level detection, ensuring precise triggering of the water supply stop command. This further improves the stability and reliability of water level control, reduces the risk of choking caused by excessive water levels, lightens the workload of caregivers, and ensures the safety of infant bathing.
[0016] Furthermore, one end of the water guiding channel near the connected static pressure chamber is located above the other end of the water guiding channel.
[0017] Beneficial effects: Utilizing the height difference, residual liquid in the connected static pressure chamber can flow smoothly back to the bathing tub after bathing, and the bottom drain outlet can centrally discharge sewage, avoiding liquid retention and simplifying the subsequent cleaning and maintenance process of the device.
[0018] Furthermore, the height difference between the two ends of the water-conducting channel is less than 1 cm.
[0019] Beneficial effects: While ensuring the smooth return of residual liquid in the connected static pressure chamber, the height difference between the liquid level in the connected static pressure chamber and the bath tub is controlled within a very small range. This avoids the actual water level in the bath tub exceeding the preset safe range due to excessive height difference at both ends of the water guiding channel, eliminates the risk of infant choking caused by excessive water level accumulation, and ensures that the water level control accuracy meets safety standards.
[0020] Furthermore, the bathing tub is equipped with an auxiliary thermostat component for dynamically maintaining the temperature of the water inside the tub.
[0021] Beneficial effects: The auxiliary thermostat can compensate for heat loss in the water during bathing, effectively reducing the rate of water temperature drop and keeping the water temperature in the bathtub consistently within a safe range suitable for infants. This avoids causing discomfort to infants due to sudden drops in water temperature and eliminates the need for caregivers to repeatedly add water and adjust the temperature, further enhancing the convenience and safety of bathing care.
[0022] Furthermore, the auxiliary thermostat component includes a temperature sensor, which is installed at the bottom of the floating force piston. Several auxiliary slots are opened on the inner wall of the bath tub, and each auxiliary slot is embedded with a zoned heating module for heating the water in the auxiliary slot. The temperature sensor is electrically connected to the main control display panel.
[0023] Beneficial effects: The temperature sensor, integrated into the bottom of the floating force-bearing piston, accurately and synchronously detects the water temperature in the bath tub using the principle of communicating vessels. This eliminates the need for additional detection elements within the tub, avoiding the risk of skin irritation from contact with the infant. The heating element in the auxiliary tub specifically compensates for heat loss during bathing. The temperature sensor provides real-time feedback of water temperature data to the main control display panel, enabling dynamic temperature control and ensuring the water temperature remains stable within a safe range throughout the bath. This reduces the risk of the infant catching a cold due to sudden temperature drops and eliminates the need for caregivers to repeatedly measure and adjust the temperature, further enhancing the convenience and safety of care.
[0024] Furthermore, each of the zoned heating modules includes an electric heating layer, and the electric heating layer corresponds one-to-one with the auxiliary slot; the width of each electric heating layer is less than 1 / 3 of the arc length of the auxiliary slot; and each electric heating layer is electrically connected to the main control display panel.
[0025] Beneficial effects: By limiting the width of the heating layer to less than 1 / 3 of the arc length of the auxiliary tank, non-uniform local heating of the water in the auxiliary tank can be achieved. The temperature difference effect drives the water in the bathing tank to form a natural convection circulation, making the heating process more gentle and uniform. This avoids the problem of sudden local water temperature rise caused by heating the entire circle, eliminates the risk of scalding the baby's skin with high temperature water, ensures the stability and reliability of water temperature control, and provides a continuous and safe constant temperature environment for baby bathing.
[0026] Furthermore, auxiliary tanks are symmetrically distributed on the two inclined inner walls of the bathing tub.
[0027] Beneficial effects: The auxiliary heating elements are symmetrically distributed on the two inclined inner walls of the bath tub, allowing the heat released by the heating components on both sides to form a symmetrical convection circulation, ensuring even heating of the water in the bath tub and avoiding the risk of scalding to infants due to localized high temperatures. At the same time, the inclined layout adapts to the lying posture of infants during bathing, and the heating area avoids direct contact with the infant's skin, ensuring rapid heat diffusion throughout the entire tub, improving the accuracy and stability of water temperature control, and further reducing the monitoring burden on caregivers.
[0028] Furthermore, all auxiliary grooves are wavy line structures.
[0029] Beneficial effects: The wavy auxiliary groove increases the contact area with the water in the bath tub, improving heat transfer efficiency and accelerating the thermal convection circulation of the water within the groove. This results in a more uniform water temperature distribution, preventing localized high or low temperature areas. Simultaneously, the wavy groove wall enhances friction with the bath rack placed inside the tub, effectively preventing the bath rack from sliding or shifting due to the baby's movements, ensuring the baby's stability while bathing and further reducing safety hazards.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0036] The following detailed description illustrates the specific implementation methods: Example 1:
[0037] like Figure 1 and Figure 2 As shown, an intelligent temperature-controlled baby bathing and care device includes a main control display panel 2, a faucet 3, a bathing platform 1, a bathing tub 5, and a closed-loop temperature-controlled water supply system. The closed-loop temperature-controlled water supply system is electrically connected to the main control display panel 2, and a drain outlet 501 is opened at the bottom of the bathing tub 5. The closed-loop temperature-controlled water supply system is a mature existing technology, mainly composed of a water storage tank, an electric heating module, a water supply pipeline, and a water pressure regulating unit. The water storage tank is stably connected to the faucet 3 through the water supply pipeline, ensuring a continuous water supply. The electric heating module can accurately heat the water in the tank to the appropriate range of 37-39℃ for infants, meeting the temperature requirements of infants' delicate skin. The water pressure regulating unit can flexibly adjust the water flow and pressure according to actual bathing needs, avoiding excessively rapid water flow that could splash or excessively slow flow that could affect bathing efficiency. The control terminal of this closed-loop temperature-controlled water supply system is electrically connected to the main control display panel 2, and can accurately respond to the start and stop commands sent by the main control display panel 2, efficiently executing water supply, heating, and shutdown actions. Its specific internal structure and working principle are common knowledge to those skilled in the art and will not be described in detail here.
[0038] The special feature of this solution is that, Figure 4 , Figure 5 and Figure 6 As shown, the shower stall 1 has a connected static pressure chamber 402. The top of the shower stall 1 is threaded with a height adjustment screw 4. At the same time, the bottom end of the height adjustment screw 4 extends into the connected static pressure chamber 402 and is integrally formed with a floating force-bearing piston 403. The floating force-bearing piston 403 slides in cooperation with the inner wall of the connected static pressure chamber 402.
[0039] A water-guiding channel 401 is provided inside the shower basin 1. The two ends of the water-guiding channel 401 are connected to the bottom of the communicating static pressure chamber 402 and the bottom of the shower tub 5, respectively, forming a complete liquid circuit interconnection structure. Utilizing the principle of communicating vessels, the liquid level in the shower tub 5 and the liquid level in the communicating static pressure chamber 402 are always consistent. For example, when 3cm of water is poured into the shower tub 5, the liquid level in the communicating static pressure chamber 402 also reaches 3cm simultaneously, eliminating the need to directly install detection elements inside the shower tub 5. A pressure sensor 404 is embedded in the bottom of the floating force piston 403, and a laser rangefinder is connected to the top of the floating force piston 403 by a screw. Both the laser rangefinder and the pressure sensor 404 are electrically connected to the main control display panel 2. In actual use, the floating force piston 403 can be moved by rotating the height adjustment screw 4. The laser range sensor collects the initial distance data between the floating force piston 403 and the top of the connected static pressure chamber 402. For example, when adapting a newborn to a 3cm safe water level, the floating force piston 403 is adjusted to the corresponding initial position by rotating the height adjustment screw 4. The main control display panel 2 automatically calibrates the preset target water level value of 3cm based on the distance data. Subsequently, the pressure sensor 404 detects the pressure of the water on the floating force piston 403 to determine whether the actual water level meets the standard.
[0040] In addition, one end of the water guiding channel 401 near the connecting static pressure chamber 402 is located above the other end of the water guiding channel 401, that is, there is a height difference between the two ends of the water guiding channel 401, and the height difference between the two ends of the water guiding channel 401 is less than 1cm. This ensures that the residual liquid in the connecting static pressure chamber 402 can be completely returned to the bathing tub 5 after bathing. At the same time, the height difference between the liquid level in the connecting static pressure chamber 402 and the bathing tub 5 is controlled within a very small range, so as to avoid the actual water level in the bathing tub 5 exceeding the preset safe range due to the excessive height difference between the two ends of the water guiding channel 401.
[0041] The main control display panel 2 is configured as follows: Initialization phase: The initial distance data between the floating force piston 403 and the top of the connected static pressure chamber 402 is collected by the laser range sensor, and the preset target water level value in the bathing tank 5 is calibrated based on the initial distance data. Water supply stage: Real-time reception of water pressure data in the connected static pressure chamber 402 collected by pressure sensor 404. When the pressure data exceeds the preset threshold, an automatic stop water supply command is output to control the closed-loop temperature control water supply system to cut off the water supply path to faucet 3.
[0042] The specific implementation process is as follows: First, the caregiver determines the target water level and water temperature according to the baby's age. For newborns, a safe water level of 3-5cm is set, and for younger infants, a suitable water level of 5-8cm is set. Then, the height adjustment screw 4 is rotated to drive the floating force piston 403 to rise and fall in the connected static pressure chamber 402. The laser range sensor collects the initial distance data between the floating force piston 403 and the top of the connected static pressure chamber 402 in real time and transmits it to the main control display panel 2. The main control display panel 2 completes the target water level calibration based on this distance, and at the same time sets the suitable bathing water temperature for infants to 37-39℃ on the panel.
[0043] After the parameters are set, the nursing staff starts the system through the main control display panel 2. Upon receiving the instruction, the closed-loop temperature-controlled water supply system starts supplying water from the storage tank. The electric heating module heats the water. Once the water temperature reaches the preset value, the water pressure regulating unit adjusts the water flow rate, and hot water is injected into the bathing tub 5 at a uniform speed through the faucet 3. As hot water is injected, the liquid level in the bathing tub 5 gradually rises. Utilizing the principle of communicating vessels, the liquid level in the communicating static pressure chamber 402 rises synchronously. When the liquid level in the communicating static pressure chamber 402 contacts the pressure sensor 404 at the bottom of the floating force piston 403, any slight rise in the liquid level in the bathing tub 5 will exert pressure on the pressure sensor 404. At this time, the pressure sensor 404 feeds back the pressure data to the main control display panel 2 (pressure data greater than 0). The main control display panel 2 immediately outputs a stop water supply command, and the closed-loop temperature-controlled water supply system then cuts off the water supply path, completing the automatic water filling process.
[0044] After bathing, open the drain port 501 at the bottom of the bathing tub 5, and the sewage in the bathing tub 5 will be discharged. The residual liquid in the connected static pressure chamber 402 will flow back to the bathing tub 5 due to the height difference of the water guiding channel 401 and be discharged together with the sewage.
[0045] Example 2:
[0046] The difference from Example 1 is that, in order to further address the problem of heat loss and rapid temperature drop in the water during the bathing process, this solution includes an auxiliary thermostat component in the bathing tub 5 for heating the water in the bathing tub 5, thereby further improving the comfort and safety of the entire baby bathing process.
[0047] Specifically, such as Figure 1 and Figure 3 The auxiliary thermostat component includes a temperature sensor 405, which is mounted at the bottom of the floating force-bearing piston 403. The inner wall of the bath tub 5 has several wavy auxiliary grooves 502, each containing a heating layer 503. Figure 7As shown, the heating layers 503 are all corresponding to the bottom of the auxiliary tank 502; the heating layers 503 and the temperature sensor 405 are both electrically connected to the main control display panel 2. At the same time, the width of the heating layers 503 is less than 1 / 3 of the arc length of the auxiliary tank 502, and the auxiliary tanks 502 are symmetrically distributed on the two inclined inner walls of the bathing tank 5.
[0048] The specific implementation process is as follows: Following the preset process of target water level (3-5cm for newborns, 5-8cm for infants) and basic water temperature (37-39℃) in Example 1, the water level is calibrated using the height adjustment screw 4 and the laser rangefinder, and the water temperature is set on the main control display panel 2. Simultaneously, the temperature sensor 405, along with the floating force piston 403, is in its initial position. After completing a self-check, it sends an initial signal back to the main control display panel 2 to ensure the auxiliary heating function is ready. Then, the closed-loop temperature-controlled water supply system heats the water at the preset temperature and fills the bathing tub 5. This process is consistent with Example 1—using the principle of communicating vessels to achieve a synchronous rise in the liquid level. After the pressure sensor 404 detects that the pressure has reached the target, the main control display panel 2 controls the closed-loop temperature-controlled water supply system to shut off the water supply, completing precise water filling.
[0049] During bathing, temperature sensor 405 uses the principle of communicating vessels to synchronously detect the water temperature in the bathing tub 5 in real time and dynamically feeds the data back to the main control display panel 2. When the water temperature drops below the preset lower limit (e.g., 37℃) due to heat loss, the main control display panel 2 immediately activates the auxiliary heating function, controlling the electric heating layer 503 in each auxiliary tank 502 to operate. Since the width of the electric heating layer 503 is less than 1 / 3 of the arc length of the auxiliary tank 502, and the auxiliary tanks 502 are symmetrically distributed on the inclined inner wall of the bathing tub 5, a local temperature difference can be formed to drive natural convection of the water. Combined with the increased heat exchange area of the wavy auxiliary tank 502, uniform heating of the water is achieved, avoiding localized high temperatures that could scald the baby.
[0050] Meanwhile, the wavy auxiliary groove 502 can enhance the friction of the bath rack and prevent the rack from sliding due to the baby's movements. For example, when the baby kicks, rolls over or twists his body during bathing, the bottom of the non-slip bathing frame and the adjustable bathing net support placed in the bathing tub 5 is closely fitted with the wall of the wavy auxiliary groove 502. The uneven wavy surface can increase the frictional resistance between the frame and the wall of the bathing tub 5, effectively reducing the side slip and displacement of the frame as the baby moves, ensuring that the baby is always in a safe lying position and reducing the risk of bumps and falls.
[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
