Description

Technical Field

[0001] The utility model belongs to the field of medical devices, and particularly relates to an oral irrigation device with adjustable temperature, adjustable pressure and replaceable irrigation head. Background Art

[0002] Oral irrigation devices are widely used in dental medical treatment, home oral care and postoperative care, and can effectively clean oral residues, remove dental plaque and improve oral hygiene. Existing oral irrigation devices mainly include handheld water flossers, electric irrigators and irrigation systems supporting dental treatment chairs. Most traditional oral irrigation devices adopt a single-channel design, that is, the irrigation fluid is sprayed into the oral cavity through a single pipeline and then flows out naturally, and the waste liquid cannot be effectively collected, which easily causes overflow of the patient's oral cavity and pollution of the operation environment. In addition, although some devices have a negative pressure suction function, the separation of the liquid suction channel and the irrigation channel is improper, and the pipeline is relatively complex, which is not convenient for maintenance and cleaning.

[0003] The existing technology mainly has the following problems in practical applications: the independence of the temperature, pressure of the irrigation fluid and the waste liquid suction function is poor, and it is difficult to form an efficient and intelligent irrigation system. First, some devices cannot accurately control the temperature of the irrigation fluid, and patients may feel uncomfortable due to too low or too high water temperature during use. Especially for people with sensitive teeth, unstable temperature will affect the use experience. Secondly, the irrigation pressure is usually in a fixed mode and cannot be adjusted according to different user needs. Some high-pressure irrigation devices may cause gum damage, while low-pressure devices cannot achieve the ideal irrigation effect. In addition, the waste liquid recovery system often depends on an external negative pressure system, and the device integration degree is low, resulting in that patients still need to rely on an additional liquid suction device during use, and the operation is cumbersome.

[0004] Therefore, aiming at the above defects of the existing oral irrigation devices, there is an urgent need to provide an oral irrigation device integrating adjustable temperature, adjustable pressure and efficient negative pressure liquid suction functions to improve the convenience, safety and hygiene of use and meet the personalized needs of different people.

This method of fixing via the connecting threaded sleeve 3 makes installation and disassembly simpler and faster. Compared to the traditional direct threaded connection, this design not only reduces the torque required during installation but also makes replacing the flushing head 4 more convenient, allowing users to easily replace and clean the flushing head.

[0039] This structure ensures a secure connection between the irrigation head 4 and the main body 1, avoiding the risk of the irrigation head loosening or falling off during use, while also providing a design that facilitates maintenance and operation. The application of the connecting screw sleeve 3 ensures both the stability of the connection and easy operation for the user, providing an efficient and convenient user experience for the entire oral irrigation device.

[0040] In this invention, the pressurized rinsing component consists of a rinsing pump, an electric pressure regulating valve, pipes, and a pressure sensor. It is primarily responsible for providing rinsing fluid at appropriate pressure, which is then used for oral cleaning via the rinsing head 4. The specific working principle and structural connection method are described below:

[0041] The flushing pump is located inside the main body 1 and is connected to the flushing chamber via an inlet pipe. The inlet pipe delivers external water to the flushing chamber. The pump's outer casing is fixedly connected to the inside of the main body 1, ensuring stability during operation and preventing displacement due to vibration or operation. The pump's outlet is connected to an outlet pipe, and the liquid is delivered to the flushing head 4 after passing through the pipe, where it is sprayed out to clean the oral cavity.

[0042] To precisely control the flushing fluid pressure, this device incorporates an electrically operated pressure regulating valve in the piping. This valve connects to the control panel 6, allowing users to adjust the desired pressure using the flushing pressure buttons on the control panel. Adjusting the valve opening controls the output pressure of the flushing pump, ensuring the flushing pressure can be adjusted as needed. The electrically controlled valve offers greater precision and convenience than traditional manual adjustment; users can easily adjust the pressure to meet the flushing needs of different users and under different oral conditions.

[0043] To ensure pressure stability during the rinsing process and avoid excessive or insufficient pressure, a pressure sensor is installed within the device. This sensor, mounted on the pipeline, monitors the liquid pressure in real time and feeds the data back to the rinsing pressure display screen on control panel 6. This allows users to visually understand the current pressure value and make further adjustments as needed to ensure optimal rinsing results.

[0044] This structural design effectively combines the functions of the rinsing pump, pressure regulating valve, pressure sensor, and pipeline, ensuring accurate delivery and pressure regulation of the rinsing fluid. It has the advantages of high efficiency, stability, and ease of operation, avoiding problems such as unstable liquid pressure or excessive rinsing fluid flow, making oral cleaning more efficient and safer.

[0045] The heating component consists of a heating tube, an electric heating element, and a temperature sensor. Its main function is to heat the rinsing fluid, ensuring a comfortable temperature experience for the user. The specific working principle and structural connection method are described below:

[0046] The heating element is installed inside the flushing chamber. Its function is to bring the heating element into close contact with the liquid flowing through the flushing chamber, thereby effectively heating the flushing fluid. An electric heating element is installed inside the heating element. This heating element generates heat through an electrical supply, thus raising the liquid temperature to the user's desired temperature. The design of the electric heating element and the connection method of the heating element ensure uniform and efficient heating, enabling the liquid to be heated quickly to the set temperature, avoiding excessive waiting time for the user.

[0047] To ensure precise temperature control and prevent overheating or overcooling, a temperature sensor is mounted on the heating element, close to the liquid flow channel, to monitor the liquid temperature in real time. The temperature sensor is connected to the temperature display and adjustment buttons via control panel 6, allowing users to adjust the temperature using the buttons on the control panel. The real-time temperature detected by the sensor is displayed on the control panel, ensuring users clearly understand the temperature of the flushing fluid and can make timely adjustments. The accuracy and response speed of the temperature sensor guarantee temperature stability, preventing excessive temperature fluctuations that could cause user discomfort.

[0048] Furthermore, the connection between the heating element and the rinsing chamber employs a robust structural design, ensuring that the heating element is not affected by vibration or pressure during operation, maintaining safe and stable operation. The electrical connections of the electric heating element and temperature sensor also have strict electrical insulation protection, ensuring safety during use.

[0049] This design allows the heating element to heat the rinsing solution precisely and evenly in a short time, ensuring that users receive a suitable temperature experience. At the same time, the temperature control system avoids discomfort caused by unstable temperature, improving the comfort and safety of the overall oral cleaning process.

[0050] The negative pressure suction unit consists of a negative pressure pump, negative pressure tubing, and a pressure sensor. It is primarily used to aspirate waste fluid from the patient's mouth and transport it to the waste fluid chamber. The design of this unit ensures efficient waste fluid recovery and disposal, prevents spillage, and maintains hygiene throughout the oral irrigation process. Its working principle and structural connection method are described below:

[0051] The negative pressure pump is located inside the main body 1. Its function is to generate suction through negative pressure to draw waste fluid from the patient's mouth through the rinsing head 4 into the device. The inlet of the negative pressure pump is connected to the rinsing head 4 via a negative pressure pipe. The waste fluid channel of the rinsing head 4 is connected to the negative pressure pipe to ensure that the waste fluid can be quickly and effectively drawn away. The negative pressure pump, through the negative pressure suction it generates, ensures that the waste fluid channel inside the rinsing head 4 generates suction, drawing the waste fluid from the mouth and transporting it through the negative pressure pipe to the waste fluid chamber, completing the waste fluid recovery process. The outlet of the negative pressure pump is connected to the waste fluid chamber to ensure that the drawn-in waste fluid flows steadily into the waste fluid chamber and is properly stored.

[0052] To ensure adjustable suction and stable liquid flow, a pressure sensor is installed on the negative pressure pipeline to monitor the negative pressure intensity in real time. This sensor detects the current suction status and feeds the pressure data back to the control panel 6. The pressure display shows the current negative pressure intensity in real time. Users can adjust the suction pressure using the suction pressure button to ensure efficient absorption of waste liquid without causing discomfort or excessive suction.

[0053] In terms of structural connection, both the inlet and outlet are provided with external threads on their outer circumferences, allowing them to be connected and secured separately via sealing caps 5. The design of sealing caps 5 not only provides effective sealing to prevent liquid leakage but also ensures a secure connection between the inlet and outlet, thus better maintaining the equipment's sealing and hygiene. Sealing caps 5 can be easily disassembled when not in use for convenient cleaning or replacement, while also ensuring the reliability and stability of the equipment during operation.

[0054] This negative pressure liquid suction system, through precise pipe layout and intelligent adjustment mechanism, not only achieves efficient waste liquid recovery but also improves the overall operating efficiency of the equipment and the user experience. Real-time monitoring and adjustment by pressure sensors ensures precise control of the negative pressure suction, avoiding potential risks caused by excessive or insufficient suction.

[0055] When using this device: ① First, the user needs to add cleaning liquid to the rinsing chamber inside the main body 1 beforehand, ensuring sufficient liquid for the entire rinsing process. The user can pour the cleaning liquid in through the liquid inlet of the main body 1, ensuring the rinsing chamber is full. ② Next, connect the rinsing head 4 to the top of the main body 1 via the connector 2 and mating head, ensuring the figure-eight interface of the connector 2 aligns accurately with the recessed groove of the mating head. The connector 2 and mating head are connected by external threads and secured with the connecting sleeve 3. Rotate the sleeve 3 until the connector and mating head are firmly engaged, preventing loosening during use. ③ After securing the rinsing head, the user can set the desired rinsing liquid temperature using the temperature adjustment buttons on the control panel 6. The temperature display on the control panel shows the current temperature in real time, ensuring a suitable and comfortable temperature. If necessary, the user can adjust the temperature using the control panel to suit individual needs. ④ Then, the user uses the rinsing pressure buttons on the control panel to adjust the desired rinsing pressure. The rinsing pressure display on the control panel shows the current pressure value in real time. The adjustment buttons can precisely adjust the rinsing liquid pressure, ensuring appropriate pressure during rinsing and avoiding excessive or insufficient pressure that may affect the effect or cause discomfort. ⑤ Simultaneously, the user can adjust the suction pressure using the suction pressure button to ensure moderate suction when the negative pressure suction component draws up waste liquid. The current suction pressure can be viewed on the suction pressure display screen on the control panel, and fine-tuned as needed. ⑥ After completing the settings, the user presses the start button to start the rinsing pump and heating component. The rinsing pump delivers the cleaning liquid from the rinsing chamber through the pipe to the rinsing head 4. The liquid is heated to the set temperature by the heating tube and electric heating element, and then delivered to the rinsing head 4 through the outlet pipe for oral rinsing. ⑦ At the same time, the negative pressure pump starts working, drawing waste liquid through the waste liquid channel of the rinsing head 4 and delivering it to the waste liquid chamber through the negative pressure pipe. The pressure sensor monitors the system pressure in real time to ensure that the pressure during rinsing and suction is within a safe range. ⑧ During rinsing, the user can adjust the liquid temperature, pressure, and suction at any time through the control panel to ensure optimal oral cleaning effect and comfort. ⑨ After use, the user simply presses the stop button to end the work, and then disassembles the rinsing head 4 for cleaning.
