Description

Technical Field

[0001] This application relates to the field of personal hygiene devices, and in particular to a portable personal hygiene device. Background Technology

[0002] Currently, bidet devices are mainly divided into two categories: portable bidets and smart toilets. Smart toilets and bidets connect to the municipal water network and use a heater to achieve a constant-temperature cleaning function, suitable for fixed home environments. The other type is portable, using bottled water or a special water tank, with a pump pressurizing the water for cleaning, suitable for outdoor travel scenarios.

[0003] However, these smart toilets and bidets are typically stationary and cannot be used in mobile settings. Portable bidets in related technologies lack heating functions, requiring the addition of warm water each time they are used, and cannot achieve long-term constant-temperature washing. Summary of the Invention

[0004] The main technical problem this application addresses is to provide a portable bidet that solves the problems of existing smart toilets being unable to perform cleaning in mobile scenarios, and portable bidets lacking heating functions and unable to achieve long-term constant temperature rinsing.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide a portable bidet, wherein the portable bidet includes: a main unit shell forming a receiving cavity; a water circuit mechanism including a water inlet filter, a water inlet pipe assembly, a water pump, a water outlet pipe assembly, a heating element, and a washer, wherein the water inlet pipe assembly, the water pump, the water outlet pipe assembly, and the heating element are disposed in the receiving cavity, one end of the water inlet filter is used to be disposed in an external water storage device, the other end of the water inlet filter is connected to the water inlet pipe assembly, the water pump is connected between the water inlet pipe assembly and the water outlet pipe assembly, the heating element is connected to the water outlet pipe assembly, and one end of the washer is detachably connected to the water outlet pipe assembly.

[0006] The water outlet pipe assembly includes a first pipe section, a second pipe section, and a quick-connect water outlet connector. The heating element is a heater. The first pipe section is connected between the water pump and the heater, and the second pipe section is connected between the heater and the quick-connect water outlet connector. One end of the cleaner is detachably connected to the quick-connect water outlet connector.

[0007] The heating element is a heating film, which is attached to the outer wall of the water outlet pipe assembly.

[0008] The main unit has a storage slot on the outer wall of the casing. The portable bidet also includes a dust cover, which is used to cover the opening of the storage slot to form a storage cavity for the other end of the bidet.

[0009] The portable bidet also includes a main unit bottom shell and a main unit sealing ring. One end of the main unit shell has a first opening, and the main unit bottom shell covers the first opening to close it. The main unit sealing ring is attached to the inner wall of the connection between the main unit bottom shell and the main unit shell.

[0010] The portable bidet also includes a core frame, an inlet water pipe assembly, a water pump, an outlet water pipe assembly, and a heating element, all of which are mounted and connected to the core frame.

[0011] The portable bidet also includes a button board and a main control circuit board. The other end of the main unit casing has a second opening, and the button board is placed over the second opening to close it. The main control circuit board is connected to the core frame and is electrically connected to the button board.

[0012] The main unit has a power interface on the outer wall of the casing. The portable bidet also includes a sealing plug, which is used to cover the power interface. The power interface is electrically connected to the main control circuit board.

[0013] The portable bidet also includes a liquid level sensor and / or a temperature sensor, which are connected to the inner wall of the water inlet pipe assembly and electrically connected to the main control circuit board.

[0014] The portable bidet also includes a buzzer, a display screen, and a voice controller. The buzzer and display screen are located on the side of the button panel away from the main control circuit board. The voice controller is connected to the core frame or the main control circuit board. The buzzer, display screen, and voice controller are electrically connected to the main control circuit board.

[0015] To solve the above-mentioned technical problems, another technical solution adopted in this application is: to provide a control method for a portable bidet, applied to the portable bidet as described above, wherein the control method for the portable bidet includes: acquiring a control command signal input by the user pressing the cleaning button on the keypad; triggering a buzzer to flash and beep a set number of times; starting the water pump after a first delay; starting the heating element after a second delay in response to a sensing feedback signal input by the liquid level sensor and / or temperature sensor being within a preset threshold range; and sequentially turning off the heating element and the water pump after triggering the display screen to show a countdown for a third time.

[0016] The beneficial effects of this application are as follows: Unlike existing technologies, the portable bidet provided by this application integrates the water inlet pipe assembly, water pump, water outlet pipe assembly, and heating element within a cavity inside the main unit's casing. This achieves a balance of portability, safety, ease of maintenance, and functionality. The main unit has a high degree of integration and a small size, making it suitable for carrying around and for use by travelers, outdoor activities, post-operative care, the elderly, and other special groups. By placing one end of the water inlet filter in an external water storage device (such as a mineral water bottle, medical purified water bottle, or saline bottle) and connecting the other end of the water inlet filter to the water inlet pipe assembly, a built-in water tank is eliminated, reducing weight, increasing flexibility, and allowing the water inlet filter to adapt to various water qualities, preventing clogging, and improving reliability. The heating element also enables instant heating for rapid warm water output, preventing bacterial growth in stored water and ensuring effective long-term constant-temperature rinsing. The use of a detachable washer also makes cleaning easier, more replaceable, and ensures hygiene and safety. Furthermore, the modular water system design facilitates maintenance, repair, and upgrades, is feasible for mass production, and is applicable to fields such as personal care, medical assistance, and smart health, with huge market potential.

[0026] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Please see Figures 1-3 ,in, Figure 1 This is an exploded view of one embodiment of the portable bidet of this application. Figure 2 yes Figure 1 Partial assembly diagram of an embodiment of a portable bidet. Figure 3 yes Figure 2 A schematic diagram of an embodiment of the water system mechanism in a portable bidet. In this embodiment, the portable bidet 1 includes a main unit housing 10 and a water system mechanism 20.

[0028] It is worth noting that this portable bidet 1 can specifically be a well-structured and fully functional personal hygiene care device. Its design takes into account portability, safety, ease of maintenance, and functionality, making it suitable for use in travel, outdoor activities, post-operative care, medical wound care, daily cleaning for the elderly, and special care scenarios for children and pregnant women. This portable bidet 1 achieves a complete process from water intake from an external water storage device → filtration and anti-clogging → pressurized delivery → heating → washing through a modular water system. It features practical characteristics such as instant heating, a detachable washing head, and anti-clogging water inlet.

[0029] Specifically, the main unit housing 10 is used to protect internal components, provide structural support and a comfortable grip, and has an internal cavity (not shown) for integrating water and electrical modules.

[0030] The water system 20 further includes an inlet filter 21, an inlet pipe assembly 22, a water pump 23, an outlet pipe assembly 24, a heating element 25, and a cleaner 26, forming a modular water system for achieving cleaning functions.

[0031] The water inlet pipe assembly 22, water pump 23, water outlet pipe assembly 24, and heating element 25 are integrated and installed in the receiving cavity inside the main unit housing 10, so that the main unit housing 10 provides protection, structural support, and a comfortable grip.

[0032] The inlet filter 21 is used to install in any reasonable water storage device, such as a mineral water bottle, a medical purified water bottle, a saline bottle, a water tank or bucket filled with cleaning water, etc., to draw water from the external water storage device and prevent impurities and sediments in the water from entering the water system, avoid the water inlet from getting stuck to the bottom and becoming blocked, play a filtering and protection role, prevent impurities from clogging the subsequent water system components, and ensure the smooth flow of water.

[0033] In some embodiments, the inlet filter 21 may have a built-in filter screen to adapt to various water qualities, prevent clogging, improve reliability, and adopt a raised bottom design to avoid direct contact with the bottom of the container. It may also be removable for cleaning, that is, the other end of the inlet filter 21 can be detachably connected to the inlet pipe assembly 22 for easy maintenance.

[0034] One end of the water inlet pipe assembly 22 is connected to the water inlet filter 21, and the other end is connected to the inlet of the water pump 23. Specifically, it may have a built-in one-way valve to prevent backflow, and a pressure sensor and / or level sensor may be installed at its interface for water shortage detection. Furthermore, one end of the water inlet pipe assembly 22 can be connected to the water inlet filter 21 using any reasonable detachable connection method, such as a quick-connect rotary connection or a threaded connection; this application does not impose any limitations on this.

[0035] The water pump 23 is connected between the inlet pipe assembly 22 and the outlet pipe assembly 24 as a power component to provide power for the flow of water, and to transport water from the inlet pipe assembly 22 to the subsequent outlet pipe assembly 24, ensuring that the water can flow smoothly within the system, so as to pressurize and transport water from the external water source to the subsequent pipeline.

[0036] The heating element 25 is connected to the water outlet pipe assembly 24 to heat the water flowing through the water outlet pipe assembly 24 and heat the water to a suitable temperature according to actual needs to meet the water temperature requirements of subsequent cleaning and other operations. It does not require water storage for heating, thus avoiding water accumulation and bacterial growth.

[0037] One end of the cleaner 26 is detachably connected to the water outlet pipe assembly 24. The connection can be made using any reasonable method, such as threads, clips, or magnetic attraction, to receive water treated by the aforementioned components. This water is then used for cleaning operations, achieving a cleaning function for specific objects, such as for travel, outdoor activities, post-operative care, medical wound care, daily cleaning for the elderly, feminine hygiene, perianal cleaning, and post-operative care. Furthermore, the cleaner 26 can be fitted with different nozzles, such as feminine wash heads or anal wash heads, and can employ mist, columnar, or pulsed water output modes. This application does not limit the specific nozzle types.

[0038] Understandably, in this water circuit mechanism 20, the water flows sequentially through the following path: first, it enters through the inlet filter 21 (filtration + anti-clogging), then flows through the inlet pipe assembly 22 into the water pump 23 (pressurization), and under the conveying action of the water pump 23, it enters the outlet pipe assembly 24. After being treated by the heating element 25 (heated to the set temperature), the water flows from the outlet pipe assembly 24 into the cleaner 26, completing the entire water flow transmission process. Finally, the cleaner 26 sprays out warm water to complete the cleaning.

[0039] The above solution integrates the inlet pipe assembly 22, water pump 23, outlet pipe assembly 24, and heating element 25 of the water circuit mechanism 20 into the internal cavity of the main unit casing 10, achieving a balance of portability, safety, ease of maintenance, and functionality. The main unit has a high degree of integration and a small size, making it suitable for carrying around and for use during travel, outdoor activities, post-operative care, and for the elderly and other special groups. By placing one end of the inlet filter 21 in an external water storage device (such as a mineral water bottle, medical purified water, or saline solution) and connecting the other end of the inlet filter 21 to the inlet pipe assembly 22, a built-in water tank is eliminated, reducing weight and increasing flexibility. The inlet filter 21 is adaptable to various water qualities, preventing clogging and improving reliability. The heating element 25 can also provide instant heating for rapid warm water output, preventing bacterial growth in stored water and effectively maintaining a constant temperature for long-term rinsing. The use of a detachable washer 26 also makes cleaning easier, more replaceable, and ensures hygiene and safety. Furthermore, the modular water system design facilitates maintenance, repair, and upgrades, making it feasible for mass production. It is applicable to fields such as personal care, medical assistance, and smart health. For example, in travel / business trips, it eliminates the need to rely on hotel hygiene conditions, as it carries its own cleaning equipment; it can be used for postpartum care, providing warm water rinsing to promote recovery and reduce the risk of infection; it can be used for the elderly / those with limited mobility to assist in cleaning and improve their self-care ability; bottled water can be used for cleaning when there is no tap water available during outdoor activities; and it can be used for postoperative recovery to keep wounds clean and avoid friction, demonstrating huge market potential.

[0040] Please continue reading. Figure 4 , Figure 4 yes Figure 1 A schematic diagram illustrating the assembly of an embodiment of a portable bidet.

[0041] In some embodiments, the portable bidet 1 may further include a water tank, which is detachably connected to the main unit housing 10 for easy carrying. Bottled water is added to the water tank so that the water filter 21 can draw water directly from it. The water tank can be a fixed tank or a detachable sterile tank with a disposable sterile liner. The liner can be replaced after use without cleaning the tank, thus improving cleaning efficiency in medical settings and making it suitable for mass use at hospital bedsides. This application does not limit its application to this specific type.

[0042] In some embodiments, the water outlet pipe assembly 24 further includes a first pipe section 241, a second pipe section 242, and a water outlet quick connector 243. The first pipe section 241 is connected between the water pump 23 and the heater, the second pipe section 242 is connected between the heater and the water outlet quick connector 243, and one end of the cleaner 26 is detachably connected to the water outlet quick connector 243.

[0043] Specifically, the heating element 25 can be any reasonable heating element such as a heating wire, a PTC (Positive Temperature Coefficient) ceramic heating element, or an electric heating tube, and is combined with a heat dissipation shell to form a heater. This application does not limit this.

[0044] The quick-connect fitting 243 is used to quickly connect the water outlet pipe so that the water after heating and other treatments can be delivered to the next component, namely the cleaner 26. It features quick connection and easy maintenance.

[0045] In other embodiments, the heating element 25 may be a heating film of any reasonable material, such as a graphene heating film or a composite heating film of polyester film and conductive ink. The heating film is attached to the outer wall of the water outlet pipe assembly 24 to achieve constant temperature through infrared heating, thereby avoiding direct contact between the heating element and water, reducing the risk of water leakage, and is suitable for medical scenarios that are sensitive to metal ions, such as burn wound irrigation scenarios. This application does not limit this.

[0046] In some embodiments, the outer wall of the main unit housing 10 is provided with a storage groove 11, and the portable bidet 1 specifically includes a dust cover 30. The dust cover 30 is used to cover the opening of the storage groove 11 to form a storage cavity (not shown in the figure) for setting the other end of the cleaner 26. That is, the storage cavity is used to accommodate the cleaner 26 as the installation area of ​​the cleaner 26. The dust cover 30 is used to cover the installation area of ​​the cleaner 26 to beautify the appearance, hide the connection structure, and assist in fixing the cleaner 26. By being assembled on the outside of the main unit housing 10 and the cleaner 26, for example by being connected to the main unit housing 10 by a buckle / screw, it fits snugly with the cleaner 26 inside, forming a wrap and fixing, improving the overall aesthetics and structural integrity.

[0047] In some embodiments, the cleaner 26 may be made of medical or food-grade plastic, with an internal fluid channel. One end of the cleaner is connected to the outlet of the heater or the output end of the water outlet pipe assembly 24, and the other end is a flushing head for guiding the heated and pressurized fluid to the user's area to be cleaned. Specifically, the cleaner 26 is used to connect to the outlet of the heater or the output end of the water outlet pipe assembly 24 via a pipe or quick-connect structure to receive hot water. Its exterior is covered by a dust cover 30, which secures its position and enhances its appearance.

[0048] In some embodiments, the portable bidet 1 further includes a main unit bottom shell 40 and a main unit sealing ring 50. One end of the main unit shell 10 is provided with a first opening (not shown in the figure), and the main unit bottom shell 40 covers the first opening to close the first opening, thereby cooperating with the main unit shell 10 to form a complete shell, supporting the weight of the device and sealing the bottom space.

[0049] Specifically, the main unit bottom shell 40 can be connected to the main unit outer shell 10 through the main unit sealing ring 50, buckle or screw to form the equipment shell and provide bottom support.

[0050] In some embodiments, the main unit sealing ring 50 may be a ring-shaped sealing ring made of silicone, rubber or any other reasonable material with good elasticity and strong sealing performance, and is attached to the inner side wall at the connection between the main unit bottom shell 40 and the main unit outer shell 10. It is used to place between the mating surfaces of the main unit outer shell 10 and the main unit bottom shell 40, and is compressed and deformed when the main unit outer shell 10 and the main unit bottom shell 40 are fastened, filling the gap to form a reliable seal and preventing water and dust from entering from the gap.

[0051] Please continue reading. Figure 5 , Figure 5 yes Figure 4 A schematic diagram of the assembly of another embodiment of the portable bidet.

[0052] In some embodiments, the portable bidet 1 also includes a shock-absorbing foot pad 60, which is installed on the side of the main unit bottom shell 40 away from the main unit outer shell 10. That is, by installing the shock-absorbing foot pad 60 on the bottom of the main unit bottom shell 40, the vibration transmission is reduced, the vibration is buffered, and the slippage is prevented.

[0053] In some embodiments, the portable bidet 1 further includes a core frame 70, on which the water inlet pipe assembly 22, water pump 23, water outlet pipe assembly 24, and heating element 25 are specifically mounted and connected to the core frame 70 to integrate and support internal components such as the water inlet pipe assembly 22 and water pump 23, arranging them in an orderly manner for easy assembly and maintenance. The core frame 70 is specifically installed in the internal space of the main unit housing 10 and the main unit bottom housing 40, and is fixed to the main unit bottom housing 40 and the main unit housing 10 by clips or screws. The water inlet pipe assembly 22, water pump 23, water outlet pipe assembly 24, and heating element 25 can also be assembled to corresponding positions on the core frame 70 using screws or slots to achieve component positioning and support; this application does not limit this specific arrangement.

[0054] In some embodiments, the portable bidet 1 further includes a button panel 80 and a main control circuit board 90, and the other end of the main unit housing 10 is provided with a second opening (not shown in the figure). The button panel 80 covers the second opening to close the second opening, thereby cooperating with the main unit housing 10 to form a complete housing. The main control circuit board 90 is connected to the core frame 70 and is electrically connected to the button panel 80.

[0055] The main control circuit board 90, based on a PCB (Printed Circuit Board), integrates one or more of the following reasonable circuit functions: power management chip, rectifier circuit, filter circuit, connector, etc. It is the core component for power supply and signal management, converting external power into a stable voltage required by internal components and distributing power. The main control circuit board 90 is mounted on the chassis frame 70 and fixed by screws or slots. Its input terminal is used to connect to an external power adapter or built-in battery to receive power input, and its output terminal is connected to circuit units such as the water pump 23, heater, and keypad 80 via wires, adjusting the operating status of each component according to control signals.

[0056] The keypad 80 is based on a PCB and integrates touch switches, circuit traces and connectors. It is a core component for human-computer interaction, converting user operation commands into electrical signals and transmitting them to the main control circuit board 90, which then drives and controls circuit units such as the water pump 23 and heater.

[0057] The circuit output terminal of the keypad 80 is electrically connected to the main control circuit board 90 via wires / connectors to transmit operation commands to control the water pump 23, heater and other actuators, thereby achieving heating and constant temperature cleaning.

[0058] Furthermore, in some embodiments, the portable bidet 1 further includes a face mask 110, which is a wear-resistant and waterproof film made of PET (polyethylene terephthalate) / PC (polycarbonate) material, with operation markings (function icons, text, etc.) printed on its surface, covering the surface of the keypad 80, for marking the operation area and protecting the keypad 80.

[0059] The faceplate 110 is attached above the button panel 80, forming an operation interface component, i.e., an operation panel, together with the button panel 80. Users can trigger electrical signals on the button panel 80 by pressing the corresponding area of ​​the faceplate 110 to achieve corresponding function control.

[0060] In some embodiments, a power interface (not shown) is provided on the outer side wall of the main unit housing 10. The portable bidet 1 also includes a sealing plug 100, which is used to cover the power interface or be embedded in the power interface of the main unit housing 10, and to seal it with the housing by interference fit, so as to block the mounting hole of the power interface of the main unit housing 10 to prevent water and dust from entering when not in operation; and the power interface is electrically connected to the main control circuit board 90, so that when the sealing plug 100 is removed to expose the power interface, an adapter or external power supply can be connected to supply power to the main control circuit board 90, the water pump 23, and the heating element 25.

[0061] In some embodiments, the sealing plug 100 may be an elastic sealing plug 100 made of silicone, rubber, resin or any other reasonable material, which has the characteristics of good elasticity and strong sealing performance. This application does not limit this.

[0062] In some embodiments, the portable bidet 1 further includes a liquid level sensor (not shown). The liquid level sensor is connected to the inner wall of the water inlet pipe assembly 22 or the water outlet pipe assembly 24 and is electrically connected to the main control circuit board 90. It is used to detect the liquid level in the water inlet pipe assembly 22 and send a liquid level feedback signal to the main control circuit board 90. This allows the main control circuit board 90 to disable the heating element 25 when there is a lack of water in the water inlet pipe assembly 22, thereby effectively preventing the heating element 25 from being activated when there is a lack of water and causing damage to the portable bidet 1, thus achieving water shortage protection.

[0063] In some embodiments, the portable bidet 1 further includes a temperature sensor (not shown), which is connected to the inner wall of the water inlet pipe assembly 22 or the water outlet pipe assembly 24 and electrically connected to the main control circuit board 90. The temperature sensor is used to detect the temperature inside the water inlet pipe assembly 22 or the water outlet pipe assembly 24 and send a temperature feedback signal to the main control circuit board 90. When the temperature inside the water inlet pipe assembly 22 or the water outlet pipe assembly 24 exceeds a set temperature threshold, the main control circuit board 90 adjusts the power of the heating element 25 or disables it, thereby effectively preventing the water temperature from becoming too hot and causing discomfort to the person using the bidet 26.

[0064] In some embodiments, the portable bidet 1 further includes a buzzer (not shown) and a display screen (not shown). The buzzer and display screen are located on the side of the keypad 80 away from the main control circuit board 90. The buzzer, display screen, and voice controller are electrically connected to the main control circuit board 90 so as to respond to the input commands of the keypad 80 and the working status parameters of the water pump 23 and the heating element 25, and the detection feedback parameters of the sensors, and / or display images to prompt the user. This application does not limit this aspect.

[0065] In some embodiments, the portable bidet 1 further includes a voice controller (not shown), which is connected to the core frame 70 or the main control circuit board 90. Specifically, it can correspond to a voice control chip or a voice control program loaded in the main control circuit board 90. This eliminates the need for manual temperature adjustment or pressing of the button panel 80. Users can simply speak the corresponding keywords to start the device. For example, it can be set to support commands such as "start medical mode" and "stop rinsing" to adjust and control the water pump 23 and heating element 25 accordingly, making it suitable for bedridden elderly users or users who cannot operate the device with their hands.

[0066] Furthermore, in some embodiments, the voice controller may also be equipped with a wireless remote control with an effective range of 5m-10m, as an aid and supplement to voice control, in order to improve the accuracy of voice recognition and the performance against environmental noise.

[0067] This application also provides a control method for a portable bidet; please refer to [link / reference]. Figure 6 , Figure 6 This is a flowchart illustrating one embodiment of the control method for the portable bidet of this application. Specifically, it may include the following steps:

[0080] S1205: After the countdown display shows the third hour, turn off the heating element and water pump in sequence.

[0081] At the same time, in response to the user's pressing operation of the cleaning button, the display screen is triggered to show the third countdown timer, and the heating element 25 and water pump 23 are turned off in sequence. During this period, in response to the user's pressing operation of the cleaning button on the button panel 80 again, the heating element 25 and water pump 23 are turned off in sequence after a fourth delay to exit the cleaning operation.

[0082] In some embodiments, the third duration is 80-100 seconds, preferably 90 seconds; the fourth duration is 1-2 seconds, preferably 1 second, and this application does not limit this.

[0083] It is worth noting that the number of times, the first duration, the preset threshold range, the second duration, the third duration, and the fourth duration can be adjusted according to different application scenarios, and this application does not limit them.

[0084] In one specific embodiment, when the user briefly presses the cleaning button, the main control circuit board 90 will control the buzzer to ring three times and flash a countdown timer. After a 3-second delay, the water pump 23 will start, and after 4 seconds, the water pump 23 will be controlled to rise from a duty cycle of 50% to the water pressure setting. The system will also check whether the sensing signals of the liquid level sensor and temperature sensor are normal. If the sensing signals are normal, the heating element 25 will be activated after a 0.5-second delay. At the same time, the display screen will be constantly lit to show a countdown, which will continue for 90 seconds before the heating element 25 and water pump 23 are turned off sequentially to automatically stop the cleaning process. If the user briefly presses the cleaning button during this period, the heating element 25 and water pump 23 will be turned off sequentially after a 1-second delay, thus ending the cleaning operation.

[0085] Specifically, users can issue commands via the control panel 110 and the button panel 80. Upon receiving the corresponding command, the main control circuit board 90 controls the water pump 23 to pump and pressurize water, which is then sent to the heating element 25 for heating. The hot water is then sprayed out through the inlet pipe assembly 22 and the outlet pipe assembly 24 to the cleaner 26 to complete the rinsing. Structurally, the main unit housing 10, the main unit bottom housing 40, and the main unit sealing ring 50 form a sealed main body. The core frame 70 supports the internal components, the dust cover 30 beautifies the area of ​​the cleaner 26, and the shock-absorbing feet 60 ensure the stability of the equipment. All components achieve functional and structural integrity through mechanical and electrical connections.

[0086] In some embodiments, the cleaning key on the keypad 80 may specifically be equipped with a "+ / -" key, so that the main control circuit board 90 replaces the "fixed-level water pressure control" with "stepless pressure regulation control", thereby adjusting the water pressure in real time to achieve continuous adjustment from 10-50 kPa; and the display screen simultaneously displays the current water pressure value to adapt to more refined medical needs, such as cavity irrigation at different depths, which is not limited in this application.

[0087] In some embodiments, the cleaning button on the button panel 80 can also be set as a scene mode button, or the voice controller can be set with corresponding scene mode keyword commands, such as one or more of any reasonable scene modes such as medical scene, elderly care scene, children and pregnant women scene; and the main control circuit board 90 is correspondingly set with a control program so that when the scene mode is adjusted to the corresponding scene mode through the scene mode button or the voice controller, the output power, working time and other states of the water pump 23 and the heater can be adjusted according to the preset control program to adapt to the cleaning needs in different scenarios; at the same time, the display screen can display the corresponding scene mode and the working status of the water pump 23 and the heater, which is not limited in this application.

[0088] In medical settings, precise temperature control is required to reduce wound risks: By employing a "dual temperature sensor + PID (Proportion Integral Differential) temperature control algorithm," and using a PTC constant temperature module for real-time heating (non-storage type), the water temperature fluctuation during rinsing is ≤±0.5℃ (degrees Celsius), in order to avoid wound irritation during rinsing after anorectal surgery or gynecological inflammation, thereby reducing the incidence of pain by more than 80% in clinical use.

[0089] The operation of elderly care scenarios needs to be simplified to improve ease of use: By designing "scenario-based one-button operation + backlit magnified display + voice prompts", elderly users do not need to manually adjust the temperature or press multiple buttons. They only need to select the corresponding scenario or say the corresponding keyword to start the device, which can reduce the spill rate by 90% and the equipment damage rate by 70%.

[0090] Safety must be ensured for children and pregnant women to reduce the risk of injury: The child mode can be activated by pressing a button or using voice to control the water pump 23 to reduce the water pressure to 10-20 kPa and the water flow rate to ≤0.5 mL / s (milliliters / second); When the pregnant woman mode is activated, the anti-backflow seal is strengthened to ensure that the rate of skin and mucous membrane damage to children is <0.5% and the rate of infection from backflow of the rinsing solution to pregnant women is <0.1%, thus meeting the standards for maternal and infant safety.

[0091] Understandably, this portable bidet 1 can cover four major scenarios—medical, elderly care, children's, and pregnant women—through scene switching, eliminating the need to purchase multiple dedicated devices and achieving versatility across multiple scenarios, thereby reducing usage costs. User purchase costs can be reduced by 60%, and storage space can be saved by 70%. Furthermore, due to the integrated over-temperature, water shortage, over-current, and backflow prevention quadruple protection, the device failure rate can be reduced to below 3%, and the service life can be extended from 1 year to 3 years (based on twice-daily use). Maintenance costs in medical scenarios are reduced by 50%, thus effectively achieving long-term safety protection and improving device reliability.

[0092] Unlike existing technologies, the portable bidet provided in this application integrates the water inlet pipe assembly, water pump, water outlet pipe assembly, and heating element into a cavity inside the main unit's casing. This design balances portability, safety, ease of maintenance, and functionality. The highly integrated and compact main unit is ideal for carrying around and is suitable for travel, outdoor activities, post-operative care, and use by the elderly and other special populations. By placing one end of the water inlet filter in an external water storage device (such as a mineral water bottle, medical purified water bottle, or saline bottle) and connecting the other end to the water inlet pipe assembly, an internal water tank is eliminated, reducing weight and increasing flexibility. The water inlet filter is adaptable to various water qualities, preventing clogging and improving reliability. The heating element provides instant heating for rapid warm water output, preventing bacterial growth in stored water and ensuring effective long-term constant-temperature rinsing. The detachable washer also facilitates cleaning, replacement, and hygiene. Furthermore, the modular water system design facilitates maintenance, repair, and upgrades, making mass production feasible. It is applicable to personal care, medical assistance, and smart health fields, with significant market potential.
