The pressing membrane 2 deforms under pressure to allow the oral care cleaning solution to be sprayed out from the nozzle 8. The lower compartment 3 is fixed to the bottom surface of the upper compartment 1; a thread outlet hole is provided on one side wall of the lower compartment 3. One end of the dental floss 4 is wound inside the lower compartment 3, and the other end extends to the thread outlet hole. The cutter is fixed inside the lower compartment 3 and positioned facing the dental floss 4 to cut the dental floss 4.

[0021] The advantages of this portable mouthwash and dental floss 4-in-1 device are as follows: Compared with the prior art, the upper compartment 1 of this portable mouthwash and dental floss 4-in-1 device has a through hole at its top, and the nozzle 8 is located on the side wall of the upper compartment 1. A pressing membrane 2 is used to seal the through hole. A lower compartment 3 is fixed below the upper compartment 1, and the floss outlet is located on the side wall of the lower compartment 3. One end of the dental floss 4 is wound inside the lower compartment 3, and the other end extends to the floss outlet. A cutter is fixed inside the lower compartment 3.

[0022] In practical application, pressing the membrane 2 increases the pressure in the space enclosed by the membrane 2 and the upper chamber 1, causing the oral care cleaning liquid to spray out from the nozzle 8. One end of the dental floss 4 is wound inside the lower chamber 3, and the other end extends to the outlet hole. The extracted dental floss 4 can be cut using a cutter. The device provided in this application integrates the functions of rinsing and flossing 4, reducing the overall size and making it easy to carry.

[0023] In some embodiments of the portable 4-in-1 dental floss device provided in this application, please refer to... Figure 1 The pressing film 2 is an upwardly convex arc-shaped structure, and the pressing film 2 is made of flexible material.

[0024] The upward-convex arc-shaped structure better conforms to the shape of the finger when pressing, making it more comfortable and convenient for users and reducing hand fatigue. Furthermore, this arc-shaped structure more effectively alters the pressure distribution within the space enclosed by the pressure membrane 2 and the upper chamber 1 during pressing. Compared to a flat structure, it increases pressure more quickly and stably, ensuring the oral care cleaning liquid is smoothly sprayed from the nozzle 8 with a force and range more suited to actual usage needs. The pressure membrane 2, made of flexible material, possesses excellent flexibility and elasticity. When pressed by the finger, the pressure membrane 2 can deform appropriately according to the force and shape of the finger, closely conforming to the finger and further enhancing pressing comfort. The oral care cleaning liquid can be either mouthwash or a breath freshener, allowing for targeted selection based on actual usage needs.

[0025] Moreover, the flexible material has good sealing properties, effectively preventing leakage of oral care cleaning solution during pressing, ensuring normal use and hygiene of the device. In actual use, users only need to gently press the curved flexible pressing membrane 2 with their fingers to easily spray out the oral care cleaning solution, making operation simple and convenient. Regarding the use of dental floss 4, the presence of the pressing membrane 2 and the rational layout of the entire device's operating area ensure that users are not interfered with by the pressing membrane 2 when using dental floss 4, allowing for smooth extraction from the floss outlet for cleaning between teeth. When it is necessary to cut the dental floss 4, the cutter accurately cuts the floss extracted from the outlet, the entire process being smooth and natural, greatly improving the efficiency and convenience of oral cleaning. This portable mouthwash and dental floss 4 two-in-one device design fully considers actual usage scenarios and user needs. Based on functional integration, the rational design of components such as the pressing membrane 2 brings users a more convenient, efficient, and comfortable oral cleaning experience.

[0026] In some embodiments of the portable 4-in-1 dental floss device provided in this application, please refer to... Figure 1 and Figure 2The nozzle 8 contains a back pressure valve 9. The back pressure valve 9 effectively controls the spray pressure and flow rate of the liquid. When the user presses the device, liquid flows through the pipe to the nozzle 8, and the back pressure valve 9 adjusts according to changes in internal pressure. This ensures that the oral care cleaning liquid or cleaning solution is sprayed evenly in the mouth with appropriate force and amount, thus more effectively cleaning the surface of teeth and between teeth. Simultaneously, the back pressure valve 9 prevents accidental leakage when not in use, ensuring a stable liquid level inside the device and improving its sealing and reliability. In daily use, users do not need to worry about liquid leakage; a gentle press is all it takes to achieve the desired cleaning effect. Moreover, this design makes the device more convenient to operate, easily meeting oral hygiene needs whether traveling or in daily life. Furthermore, the presence of the back pressure valve 9 helps extend the device's lifespan and reduces the risk of damage to internal components due to liquid leakage. It works in conjunction with other components of the portable mouthwash and dental floss 4-in-1 device to provide users with an efficient, convenient, and reliable oral hygiene experience.

[0027] In some embodiments of the portable 4-in-1 dental floss device provided in this application, please refer to... Figure 1 The upper compartment 1 and lower compartment 3 are integrally molded. The lower compartment 3 contains a spool for storing dental floss 4, which rotates smoothly for easy extraction. When floss 4 is needed, an appropriate amount can be easily pulled out through the opening at the front of the lower compartment 3 for teeth cleaning. When rinsing is required, the cap of the upper compartment 1 is opened, and mouthwash is forced into the mouth through the nozzle 8. This integral design not only makes the device compact and portable but also ensures a stable connection between the upper compartment 1 and lower compartment 3, reducing inconvenience and the risk of damage caused by component separation. Furthermore, the integral shell is easier to clean and maintain, effectively preventing bacteria from growing in the crevices and providing users with a healthier and more hygienic oral care experience.

[0028] In some embodiments of the portable 4-in-1 dental floss device provided in this application, please refer to... Figure 1 The lower compartment 3 contains a fixed spool, and one end of the dental floss 4 is wound around the spool. The spool is rotatably mounted within the lower compartment 3. When the dental floss 4 is needed, rotating the spool gradually releases the floss, making it easy for the user to remove and use it to clean between teeth. During use, the part of the dental floss 4 that contacts the teeth effectively removes food debris and plaque from between teeth. Simultaneously, to ensure smooth rotation of the spool, a lubrication mechanism is provided within the lower compartment 3 to reduce frictional resistance between the spool and the lower compartment 3.

[0029] In some embodiments of the portable 4-in-1 dental floss device provided in this application, please refer to... Figure 1 and Figure 2 The upper compartment 1 is fitted with a protective cover 6, which seals the nozzle 8 and covers the floss outlet. The protective cover 6 connects to both the upper compartment 1 and the lower compartment 3 via a connector, making its opening and closing convenient. When the protective cover 6 is closed, it effectively prevents dust and debris from entering the nozzle 8 and the floss outlet, avoiding clogging the nozzle 8 and affecting its normal rinsing function, and preventing the dental floss 4 from becoming soiled or contaminated with dust and other impurities, ensuring the cleanliness and proper floss delivery of the dental floss 4. When using this portable mouthwash and dental floss 4-in-1 device, simply open the protective cover 6 to expose the nozzle 8 and the floss outlet for operation. After operation, closing the protective cover 6 restores the device to its protective state, making it convenient for people to carry and use in various scenarios, effectively maintaining oral hygiene.

[0030] In some embodiments of the portable 4-in-1 dental floss device provided in this application, please refer to... Figure 1 and Figure 2 The inner wall of the protective cover 6 is equipped with a sealing post 7. The sealing post 7 engages with the nozzle 8 via the swinging motion of the protective cover 6 to seal the nozzle 8. As the protective cover 6 moves, the sealing post 7 gradually approaches the nozzle 8 until it is fully inserted into the nozzle 8, effectively sealing it. This design prevents internal liquids or other substances from leaking out of the nozzle 8 when the device is not in use, avoiding contamination or waste. Simultaneously, this interlocking mechanism ensures a tight seal, reducing the possibility of external dust and other impurities entering the device. When needed, simply pull out the protective cover 6 again, and the sealing post 7 can be removed from the nozzle 8, restoring its unobstructed flow for rinsing or flossing. This simple yet ingenious structural design ensures both the device's airtightness and ease of use, providing users with a more hygienic and practical oral hygiene experience.

[0031] In some embodiments of the portable 4-in-1 dental floss device provided in this application, please refer to... Figure 1The lower compartment 3 contains a positioning clip 5, which rests against the dental floss 4 and is positioned on the inner wall of the lower compartment 3 to secure the dental floss 4. Specifically, the positioning clip 5 has a specific shape that fits snugly against the dental floss 4, firmly holding it in place without causing excessive pressure or damage. The positioning clip 5 is cleverly designed to connect to the inner wall of the lower compartment 3, ensuring it will not easily loosen or shift during use. When the dental floss 4 is placed in the positioning clip 5, it is precisely positioned in the appropriate location, allowing the user to smoothly obtain the desired length of floss when withdrawing it, and ensuring a relatively uniform length of floss each time, facilitating effective oral cleaning. Furthermore, this positioning clip 5 helps maintain the neatness and order of the dental floss 4, preventing tangling or confusion during use, thereby improving the convenience and reliability of this portable mouthwash and dental floss 2-in-1 device. Meanwhile, the material selection of the positioning clip 5 is also crucial. It needs to have a certain degree of flexibility and wear resistance to adapt to the friction of the dental floss 4 during continuous extraction and use, ensuring that it can stably and long-term fix the dental floss 4. The positioning clip 5 includes a positioning head and a spring. The spring compresses the positioning head, and the positioning head presses the dental floss 4 against the inner wall of the lower compartment 3.

[0032] In some embodiments of the portable 4-in-1 dental floss device provided in this application, please refer to... Figure 1 and Figure 2 The cutter includes a pressure plate 10 and a blade 11. The blade 11 is fixed to the back of the pressure plate 10 and cuts the dental floss 4 by means of the movement of the pressure plate 10. Specifically, the shape of the pressure plate 10 is designed to fit the comfortable angle of human fingers, making it easy for users to apply force. When the user presses the pressure plate 10, the pressure plate 10 moves the blade 11 downward. The blade 11 is sharp and durable, and can accurately cut the dental floss 4. After cutting the dental floss 4, the user can easily remove the dental floss 4 for use. At the same time, to ensure the safety of the blade 11, a specific protective structure prevents accidental cuts by the blade 11 when the device is not in use. A layer of elastically retractable spring is provided around the blade 11. When the pressure plate 10 is not pressed, the spring is in an extended state, completely covering the blade 11. When it is necessary to cut the dental floss 4, the pressure plate 10 is pressed down, the spring elastically contracts, and the blade 11 cuts the dental floss 4.

[0033] In some embodiments of the portable 4-in-1 dental floss device provided in this application, please refer to... Figure 1 and Figure 2A spring is installed between the lower compartment 3 and the pressing plate 10. This spring can generate elastic deformation when the pressing plate 10 is pressed, providing power support for subsequent operations such as the dispensing of dental floss 4. When the user presses the pressing plate 10, the spring compresses and accumulates energy. Then, when the pressing plate 10 is released, the spring rebounds, driving the connected components to smoothly dispense the dental floss 4, facilitating oral cleaning. Moreover, by reasonably designing the spring's elastic coefficient and other parameters, it can be ensured that the force required to dispense the dental floss 4 is moderate, neither too strong to cause inconvenience nor too weak to effectively dispense the dental floss 4. At the same time, the stability of the spring is also crucial during long-term use. It needs to ensure continuous and reliable operation without problems such as elasticity decay, in order to maintain the normal performance of the entire portable mouthwash and dental floss 2-in-1 device.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
