Description

Technical Field

[0001] This invention relates to the field of bathroom equipment technology, and in particular to a portable bidet with liquid heating function and a split design, suitable for scenarios such as daily home care, outdoor travel, and postoperative rehabilitation. Background Technology

[0002] Traditional portable flushers have two major pain points in practical use:

[0003] Insufficient comfort: Without heating function, the liquid temperature is greatly affected by the environment, especially in winter or low temperature environment. Direct contact of low temperature liquid with the skin will cause irritation and reduce the user experience. It is even more unfriendly to sensitive people (such as pregnant women, postpartum patients, and postoperative patients).

[0004] Portability versus functionality conflict: Most existing rinsers with integrated heating modules adopt an integrated design. In order to accommodate the heating element and large-capacity battery, the device volume usually exceeds 200cm³ and the weight is greater than 300g, resulting in poor portability. Moreover, due to circuit design limitations, most products require the heating and rinsing functions to be cut off when charging, making them unsuitable for emergency use.

[0005] Therefore, the market urgently needs a washing device that combines heating function, portability, and ease of use. Summary of the Invention

[0006] This invention aims to solve the problems of "low-temperature liquids affecting comfort", "bulky integrated heating devices", and "inability to use while charging" in existing technologies, and provides a portable, heatable bidet that achieves the following objectives through a split power supply and heating scheme:

[0007] Precisely heats liquids to a comfortable temperature for the human body, enhancing the user experience;

[0008] Optimize the structural design to reduce overall size and weight, and enhance portability.

[0009] This invention provides a portable, heatable flushing device, comprising a base, a liquid storage chamber, and a nozzle module. The bottom of the liquid storage chamber is mounted on top of the base, and the base contains a battery, a heater, and a control circuit for heating the liquid in the storage chamber. The nozzle module is detachably mounted on top of the liquid storage chamber and contains a water pump, an inlet pipe, an outlet pipe, an independent battery, and a control circuit. The water pump draws liquid from the storage chamber through the inlet pipe, heats it, and then sprays it out through the outlet pipe.

[0010] Furthermore, the base also includes a first charging port, a heating button, a first PCB board, and a temperature sensor. The first PCB board is electrically connected to the first charging port, the heating button, and the temperature sensor to automate and refine the heating process, avoiding errors caused by manual temperature control. The unified control logic simplifies circuit design and improves device stability. The independent heating button facilitates quick operation for users and lowers the barrier to entry.

[0011] Furthermore, a waterproof plug is provided at the first charging port, which fits tightly against the interface when the charging port is not in use, forming a physical sealing barrier to prevent liquid from entering the charging port.

[0012] Furthermore, a display screen electrically connected to the first PCB board is provided on the side of the base, allowing users to intuitively monitor the heating progress and remaining power, avoiding blind waiting or heating interruption due to insufficient power.

[0013] Furthermore, the top of the liquid storage chamber is connected to the bottom of the nozzle module via threads for easy water addition.

[0014] Furthermore, the nozzle module also includes a rotatable folding arm, which can be stored on the side of the nozzle module. The folding arm is connected to the water outlet pipe, and a water outlet nozzle is provided on the folding arm. The folding arm adopts a damped pivot design, which can rotate 0-180° around the nozzle module to adjust the angle of the water outlet nozzle. When not in use, the folding arm can be stored in a groove on the side of the module to reduce space occupation. The hollow interior of the folding arm is connected to the water outlet pipe to form a liquid delivery channel.

[0015] Furthermore, the second PCB board of the nozzle module is electrically connected to the water pump, the water outlet button, the second charging port, and the second battery. The second PCB board serves as the independent control core of the nozzle module, receiving commands from the water outlet button (start / stop rinsing) to control the water pump to extract liquid; simultaneously, it manages the charging and discharging of the second battery, ensuring that the water pump can still operate independently when detached from the base.

[0016] Furthermore, the nozzle module includes a bottom cover, a middle shell, and a top cover. The middle shell and the top cover have grooves for accommodating the folding arm, and the water outlet button is located in the center of the groove. The modular shell design reduces production and maintenance costs; the grooves allow the folding arm to form an integral part with the module body, preventing damage to protruding parts; the button is centrally located and easy to operate, reducing the probability of accidental activation.

[0017] Furthermore, the nozzle module incorporates a built-in water level detection system. If no water or insufficient water is detected after startup, it automatically stops operation and prevents repeated restarts within a short period. The water level detection system monitors the liquid level in the storage chamber through a liquid level sensor and transmits the signal to the second PCB board. When the detected value is lower than the threshold, the second PCB board triggers a protection mechanism, cutting off the power supply to the water pump and locking the startup function.

[0018] More preferably, the base is detachably connected to the liquid storage chamber via a snap-fit, and the base can be removed after heating is complete, reducing the overall weight.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] Enhanced comfort: Precise heating to 38±3℃ solves the problem of irritation from low-temperature liquids, making it especially suitable for winter or sensitive individuals;

[0021] Portability optimization: The split design makes it easy to carry around and use;

[0022] Enhanced safety: Features water level detection, low voltage protection, waterproof design, and overheat protection to reduce usage risks. Attached Figure Description

These drawings and descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0036] Please refer to Figures 1-8. The portable heated rinsing device disclosed in this invention adopts a modular design, consisting of a base 1, a liquid storage chamber 2, and a nozzle module 3. These three components are mechanically connected and work together with electrical circuitry to achieve liquid heating, extraction, and spraying functions. In its assembled state, the overall size is moderate, effectively meeting portability requirements.

[0037] As shown in Figure 8, the base 1, as the core component for heating and power supply, supports the liquid storage chamber 2 and provides heating function. It contains a first battery 15, a heater 16, and a control circuit. The liquid storage chamber 2, made of food-grade material, stores the liquid to be heated and is physically bonded to the base 1 for heat conduction. As shown in Figures 4 and 7, the nozzle module 3 can independently extract and spray the liquid. It contains a second battery 39, a water pump 31, and a control circuit. It can be separated from the liquid storage chamber 2 and used independently. After heating is complete, the base 1 can be removed to reduce overall weight, and the liquid storage chamber 2 can be directly used with the nozzle module 3.

[0038] As shown in Figure 8, the base 1 has a cylindrical structure, using ABS engineering plastic as the outer shell with an anti-slip surface and a silicone pad 11 at the bottom to effectively prevent slippage during placement. The first battery 15 is embedded in a groove at the bottom of the base 1 and electrically connected to the first PCB board 12 via a nickel strip. It also has overcharge and over-discharge protection functions. When the voltage is below 3.2V, it will trigger low-voltage protection, and when it is above 4.2V, it will stop charging. The heater 16 uses a PTC heating element, which is installed close to the contact surface at the bottom of the liquid storage chamber 2. It is physically connected to the liquid storage chamber 2 via thermally conductive silicone. After power is applied, the PTC element heats up and transfers heat to the liquid in the liquid storage chamber 2 through thermal conduction. When the temperature reaches 45℃, the PTC resistance will increase sharply, achieving self-temperature limiting and thus preventing overheating. The core components of the first PCB board 12 include an STM32F030 microcontroller as the main controller, a DS18B20 temperature acquisition chip, and a TP4056 power management chip. Its main functions are to receive commands from the heating button 14 and signals from the temperature sensor, control the start and stop of the heater 16, manage the charging and discharging of the first battery 15, and drive the display screen to show the device status. In this embodiment, the temperature sensor uses an NTC thermistor with an accuracy of ±0.5℃, installed on the contact surface at the bottom of the liquid storage chamber 2. It can collect the liquid temperature in real time and transmit data to the first PCB board 12 every 0.5 seconds. When the temperature reaches 38±3℃, a heating stop signal is triggered. The first charging port 13 supports DC 5V / 0.5-1A input and is equipped with a silicone waterproof plug 17, achieving an IPX4 waterproof rating. When the charger is plugged in to charge the first battery 15, the blue indicator light flashes slowly at a frequency of 1Hz to indicate charging; a solid blue light indicates a full charge, which takes approximately 2 hours. The heating button 14 is a silicone touch button with a tri-color LED indicator integrated on the edge. A solid orange light indicates that heating is in progress, a red light flashes 5 times every 2 seconds to indicate a low voltage alarm, and a slow flashing or solid blue light indicates the charging status.

[0039] In some embodiments, a display screen may be installed on the base 1 to display the real-time liquid temperature, the power level of the first battery 15, and the heating status icon, installed on the side of the base 1 in a direction perpendicular to the heating button 14.

[0040] The storage chamber 2 is a transparent cylindrical container with a capacity of 200mL, marked with graduations of 50mL, 100mL, 150mL, and 200mL. The bottom of storage chamber 2 is connected to the top of base 1 via a snap-fit ​​connection, and the contact surface is lined with a 0.5mm thick aluminum foil layer to enhance heat conduction efficiency. Storage chamber 2 exhibits excellent high-temperature resistance, capable of withstanding long-term storage of 60℃ hot water without deformation or odor.

[0041] In this embodiment, the water pump 31 inside the nozzle module 3 is a miniature DC diaphragm pump with a voltage of 3.7V, a flow rate of 150mL / min, and a head of 1.5m. It is fixed by a silicone shock-absorbing pad and controlled by the second PCB board 34. It starts after receiving a signal from the water outlet button 35 and draws liquid from the storage chamber 2 to the water outlet pipe 33. Both the inlet pipe 32 and the outlet pipe 33 are made of food-grade silicone tubing. One end of the inlet pipe 32 is connected to the inlet of the water pump 31, and the other end extends to the bottom of the storage chamber 2. One end of the outlet pipe 33 is connected to the outlet of the water pump 31, and the other end is connected to the internal channel of the folding arm 36. The folding arm 36 can rotate 0-180° around the pivot of the nozzle module 3. The water outlet nozzle 361 is located at the end of the folding arm 36, and different types of sprays can be achieved by replacing the nozzle.

[0042] The middle shell 371 and the top cover 372 have grooves that match the shape of the folding arm 36, allowing the folding arm 36 to be fully inserted when stored. The second charging port 38 is a Type-C interface, located on the top of the nozzle module 3, and sealed by the seal 373. The second PCB board 34 is equipped with an STM8S003 microcontroller, which is responsible for receiving signals from the water dispensing button 35, water volume detection system data, controlling the start and stop of the water pump 31, and the charging and discharging of the second battery 39; the water dispensing button 35 is located in the center of the groove, supporting single-press start, repress stop, or long press for 2 seconds to lock to prevent accidental touch. The water level detection system uses an infrared photoelectric sensor, with the transmitter and receiver installed on opposite sides of the connection between the liquid storage chamber 2 and the nozzle module 3. When the liquid level is below the 50mL threshold, the infrared light refraction path changes, the signal strength at the receiver decreases, and the second PCB board 34 determines that the water level is insufficient. After detecting insufficient water level, the power supply to the water pump 31 is immediately cut off, and the water dispensing button 35 is locked, preventing restarting within 30 seconds. The system also emits a 1-second prompt sound at a frequency of 2kHz via a built-in buzzer.

[0043] The circuit control system of this invention is divided into a base 1 control loop and a nozzle module 3 control loop. The two operate independently and achieve functional coordination through mechanical connection. In the heating control process, when the first battery 15 has a charge of ≥10%, the device is in standby mode, and the display shows the current ambient temperature and charge level. After pressing and holding the heating button 14 for 2 seconds, the first PCB board 12 receives the signal and drives the heater 16 to power on, the orange LED lights up, and heating begins. The temperature sensor feeds back data every 0.5 seconds, and the microcontroller compares the data with the target value of 38±3℃ in real time. When the temperature reaches 35℃, the power of the heater 16 is reduced from 15W to 5W to avoid overheating. When the temperature reaches 41℃, the power supply to the heater 16 is immediately cut off, the orange LED turns off, or the user can press and hold the heating button 14 for 2 seconds to forcibly stop heating. In the rinsing control process, after the nozzle module 3 is connected to the liquid storage chamber 2, the water volume detection system will automatically start and enter a 10-second detection window period. If sufficient water volume is detected, the water pump 31 is in a standby state. At this time, pressing the water outlet button 35 will drive the water pump 31 to work, and the liquid will be sprayed out from the water outlet nozzle 361 through the water inlet pipe 32, the water pump 31, and the water outlet pipe 33. Pressing the water outlet button 35 again will stop the water pump 31 from working. If insufficient water volume is detected within the detection window period, a buzzer will sound and the button will be locked for 30 seconds.

[0044] In actual use, the operation varies slightly depending on the scenario. For daily home use, first fill the reservoir 2 with clean water and connect it to the base 1. Press and hold the heating button 14 to start heating. The display screen shows the temperature change in real time. Once the temperature reaches 38±3℃, connect the nozzle module 3 to the reservoir 2, remove the base, rotate the folding arm 36 to adjust the angle as needed, and press the water outlet button 35 to rinse. After use, disassemble the parts, wipe them clean with a dry cloth, and store them. For postoperative recovery patients, the temperature can be adjusted to a suitable range, and a comfortable rinsing angle can be found by rotating the folding arm 36. The water volume detection system can prevent the water pump 31 from running dry due to insufficient liquid, ensuring safe use.

[0045] This invention achieves an effective combination of heating function, portability, and safety through reasonable structural design and circuit control. The materials selected for each component meet the requirements of food safety and durability. The operation process is simple and intuitive, and it can meet the usage needs of various scenarios such as home, outdoor, and postoperative care.
