[0069] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0070] Please refer to Figures 1 to 10This utility model provides a cup structure, including: a cup body 900, with a mixing chamber 901 disposed within the cup body 900; and a connecting part 909 disposed on the cup body 900, with a liquid outlet channel 904 disposed within the connecting part 909. The connecting part 909 is used to connect to a cleaning liquid containing structure 300, and the two ends of the liquid outlet channel 904 are respectively used to communicate with the cleaning liquid containing chamber 301 and the mixing chamber 901 of the cleaning liquid containing structure 300, so that the cleaning liquid in the cleaning liquid containing chamber 301 is injected into the mixing chamber 901. This design allows the cleaning liquid in the cleaning liquid containing structure 300 to flow smoothly into the mixing chamber 901, mix with water or other liquids, and form mouthwash. The principle is based on the tight fit between the cleaning liquid containing structure 300 and the connecting part 909 to ensure accurate delivery of the cleaning liquid. The cup structure designed in this application can easily obtain an appropriate amount of cleaning liquid, avoiding the waste or inaccurate dosage problems that may occur when manually pouring. The user connects the cleaning liquid holding structure 300 to the connecting part 909, so that the cleaning liquid in the cleaning liquid holding structure 300 flows into the mixing chamber 901 through the liquid outlet 904, mixes with water and is used for rinsing. After the cleaning liquid is filled or the cleaning liquid is exhausted, the user can directly remove the cleaning liquid holding structure 300.

[0071] The cleaning solution reservoir 300 is detachably connected to the connecting part 909. This detachable connection is designed to facilitate the replacement of the cleaning solution reservoir 300, ensuring the cup structure can continuously use different types of cleaning solutions. The cup structure of this application allows for quick replacement of the cleaning solution reservoir 300 according to personal preference or oral health needs, improving the versatility and personalization of the cup structure. When the cleaning solution in the reservoir 300 is depleted, the user can easily detach it from the connecting part 909, replace it with a new one, and then reconnect it to the connecting part 909 to replenish the cleaning solution.

[0072] Specifically, the connecting part 909 protrudes from the side wall of the cup body 900, and extends from the side wall of the cup body 900 in a direction away from the cup body 900; or, the connecting part 909 is embedded in the cup body 900. This arrangement makes it easy to connect the cleaning liquid containing structure 300 to the cup body 900. When rinsing is required, the cleaning liquid containing structure 300 is directly connected to the cup body 900 through the connecting part 909, so that the cleaning liquid containing cavity 301 is connected to the mixing cavity 901. When rinsing is not required, the cleaning liquid containing structure 300 can be directly removed. In addition, the cup body structure can also accommodate other cleaning components, such as a mouthwash powder containing structure.

[0073] In one embodiment of this utility model, the connecting part 909 includes a protruding block, and a liquid outlet channel 904 is disposed on the protruding block. The protruding block extends from the cup body 900 in a direction away from the cup body 900, and is used to connect with the cleaning liquid containing structure 300. By extending the protruding block on the cup body 900, it is convenient to install the cleaning liquid containing structure 300. During use, the cleaning liquid containing structure 300 is located outside the mixing chamber 901, ensuring the cleanliness of the inside of the mixing chamber 901 and facilitating the observation of the liquid volume inside the mixing chamber 901.

[0074] In practical implementation, the protruding block is provided with a threaded structure for threaded connection with the cleaning fluid containing structure 300; or, the protruding block is provided with a snap-fit ​​rib for snap-fit ​​connection between the protruding block and the cleaning fluid containing structure 300. Through threaded connection or snap-fit, users can easily connect the cleaning fluid containing structure 300 to the connecting part 909 without the need for a complex installation structure, making operation simple and convenient.

[0075] In another embodiment of this utility model, the connecting part 909 is embedded in the cup body 900. The connecting part 909 includes a connecting opening, and a liquid outlet channel 904 is disposed in the connecting opening. The connecting opening is used to connect with the cleaning liquid containing structure 300. In this embodiment, a threaded structure is provided in the connecting opening for threaded connection with the cleaning liquid containing structure 300. This arrangement facilitates the removal and installation of the cleaning liquid containing structure 300 from the cup body 900.

[0076] A connecting part 909 is disposed on the outer wall surface of the cup body 900, and the cleaning liquid containing structure 300 is detachably connected to the cup body 900 via the connecting part 909. The principle of this design is to place the cleaning liquid containing structure 300 outside the cup body 900 for easy observation and replacement, while also avoiding the cleaning liquid containing structure 300 occupying the internal space of the mixing chamber 901. The cup body structure of this application is partially or entirely made of transparent material, improving the visual transparency of the cup body structure and allowing users to intuitively see the status of the cleaning liquid containing structure 300, while ensuring the maximum capacity of the mixing chamber 901. Users install the cleaning liquid containing structure 300 on the outer wall of the cup body 900 via the connecting part 909. After use, the liquid level in the cleaning liquid containing structure 300 can be directly observed; when replacing the cleaning liquid containing structure 300, it is not necessary to open or disassemble the cup body 900. The connecting part 909 protrudes from the outer wall surface of the cup body 900, and may be disposed on, but is not limited to, the top, side, or bottom surface of the cup body 900.

[0077] The cup body 900 includes a first body 910 and a second body 920. A mixing chamber 901 is disposed within the first body 910, and a connecting part 909 is disposed on the second body 920. The first body 910 and the second body 920 are slidably disposed relative to each other, or the first body 910 and the second body 920 are detachably connected, or the first body 910 and the second body 920 are an integral structure. Through the relative sliding or detachable connection of the first body 910 and the second body 920, the cleaning liquid containing structure 300 can quickly dispense liquid. The detachable connection of the first body 910 and the second body 920 facilitates the replacement and use of the cleaning liquid containing structure 300. The integral structure of the first body 910 and the second body 920 enhances the overall structural strength of the cup body. Users can easily adjust the position of the cleaning liquid containing structure 300, making it easy to operate when needed, and maintaining the neat appearance of the cup body 900 when not needed. Users can slide or detach the first body 910 and the second body 920 as needed to adjust the usage state of the cleaning liquid containing structure 300.

[0078] The liquid outlet channel 904 includes a first outlet section 9041, with its two ends connected to the cleaning liquid containing structure 300 and the mixing chamber 901, respectively. The cup structure also includes a liquid-blocking component 905, disposed within the mixing chamber 901. The liquid-blocking component 905 is positioned opposite and spaced apart from the first outlet section 9041 to block the cleaning liquid flowing out of the first outlet section 9041. The liquid-blocking component 905 controls the mixing rate of the cleaning liquid with the liquid in the mixing chamber 901, preventing the cleaning liquid from splashing out of the cup or towards the user. The cleaning liquid of this application can be uniformly mixed with the liquid in the mixing chamber 901 to form an ideal mouthwash concentration. When the cleaning liquid flows into the mixing chamber 901 through the first outlet section 9041, the liquid-blocking component 905 acts as a barrier, allowing the cleaning liquid to mix slowly and uniformly with the liquid in the mixing chamber 901.

[0079] The cup body 900 also includes: a mounting cavity 903 disposed on the side of the mixing cavity 901, and a connecting portion 909 disposed on the inner wall surface of the mounting cavity 903, so that after the cleaning liquid containing structure 300 is connected to the connecting portion 909, at least a portion of the cleaning liquid containing structure 300 is movably disposed within the mounting cavity 903.

[0080] The mounting cavity 903 is located above, below, or to the side of the mixing cavity 901. This design optimizes the flow path of the cleaning fluid by rationally arranging the cleaning fluid receiving structure 300 and the mixing cavity 901, thereby improving mixing efficiency. The cleaning fluid in the cleaning fluid receiving structure 300 can mix with the liquid in the mixing cavity 901 more quickly and evenly, forming a high-quality mouthwash. The user places the cleaning fluid receiving structure 300 into the mounting cavity 903 and operates the cup structure to allow the cleaning fluid in the cleaning fluid receiving structure 300 to flow into the mixing cavity 901, where it mixes with the pre-existing liquid, completing the preparation of the mouthwash.

[0081] This utility model also provides a mouthwash cup, including a cup body structure and a cleaning liquid containing structure 300. The cleaning liquid containing structure 300 is detachably connected to the cup body structure. Cleaning liquid is injected into the cup body structure through the cleaning liquid containing structure 300. The cup body structure is the cup body structure of the above embodiment.

[0082] Specifically:

[0083] like Figure 1 and Figure 2 As shown, in the first embodiment of this application, the first body 910 and the second body 920 are slidably disposed relative to each other. When the first body 910 and the second body 920 slide to a first relative position, the cleaning fluid receiving cavity 301 communicates with the mixing cavity 901. When the first body 910 and the second body 920 slide to a second relative position, the cleaning fluid receiving cavity 301 and the mixing cavity 901 are separated. A first guide portion 911 is provided on the first body 910, and a second guide portion 921 is provided on the second body 920. The first guide portion 911 and the second guide portion 921 are interlocked to guide the first body 910 when it moves. By utilizing the cooperation of the first guide portion 911 and the second guide portion 921, the stability and accuracy of the first body 910 and the second body 920 during relative sliding are ensured. This application improves the structural stability of the cup structure and the user experience, avoiding shaking or misalignment during the sliding process. The user adjusts the position of the cleaning fluid containing structure 300 by sliding the first body 910 and the second body 920. The interlocking of the first guide part 911 and the second guide part 921 ensures smooth and precise sliding. Specifically, the first guide part 911 is an insertion ring, and the second guide part 921 is an insertion groove. The insertion groove extends vertically to ensure that the first body 910 and the second body 920 reciprocate under the action of the insertion ring and the insertion groove.

[0084] The piston assembly 330 is connected to the first body 910. By pressing the first body 910 or the second body 920, the piston assembly 330 moves relative to the cleaning fluid receiving cavity 301, squeezing the cleaning fluid in the cleaning fluid receiving cavity 301 into the mixing cavity 901. When the first body 910 and the second body 920 slide to the first relative position, the cleaning fluid receiving structure 300 moves to the position where it squeezes against the piston assembly 330. At this time, the piston assembly 330 squeezes the cleaning fluid in the cleaning fluid receiving cavity 301 into the mixing cavity 901. When the first body 910 and the second body 920 slide to the second relative position, the cleaning fluid receiving structure 300 moves to the initial position, and the piston assembly 330 does not apply squeezing force to the cleaning fluid in the cleaning fluid receiving cavity 301, thus separating the cleaning fluid receiving cavity 301 from the mixing cavity 901.

[0085] The design of the piston assembly 330 connected to the first body 910 allows pressing the first body 910 or the second body 920 to directly cause relative movement of the piston assembly 330 within the cleaning fluid receiving cavity 301. This direct mechanical connection ensures that the pressing action is efficiently converted into a squeezing process of the cleaning fluid, improving the transfer efficiency and response speed of the cleaning fluid. When the user presses the first body 910 or the second body 920, the piston assembly 330 moves due to its fixed connection with the first body 910, thereby compressing the volume within the cleaning fluid receiving cavity 301 and forcing the cleaning fluid into the mixing cavity 901 through the connecting channel. This design simplifies the process of transferring the cleaning fluid from the oral cleaning fluid receiving structure to the mixing cavity 901, avoids complex transmission structures, reduces energy loss during the transfer process, and makes the pressing action more intuitively associated with the squeezing effect of the cleaning fluid, improving the directness of the user experience and the reliability of the product. Furthermore, the connection between the piston assembly 330 and the first body 910 ensures the stability and positioning accuracy of the piston assembly 330, reducing potential shifts or loosening during pressing, and further improving the stability and precision of the cleaning fluid delivery. This design facilitates the quantitative delivery of the cleaning fluid, ensuring that the ratio of cleaning fluid to water in the mixing chamber 901 remains consistent each time it is used, thus improving the consistency and predictability of the cleaning effect.

[0086] In this embodiment, the cleaning fluid containing structure 300 is connected to the second body 920. To improve the connection stability between the second body 920 and the cleaning fluid containing structure 300, the second body 920 is also provided with a slot 923. The slot 923 is arranged around the second guide portion 921. A mating groove 9230 is provided on the groove wall of the slot 923. The mating groove 9230 extends along the circumferential direction of the slot 923. An extension plate 314 is provided on the capsule shell assembly 310. A mating protrusion 3140 is provided on the extension plate 314. The extension plate 314 is inserted into the slot 923, and the mating protrusion 3140 is engaged in the mating groove 9230. This prevents the cleaning fluid containing structure 300 from detaching from the second body 920. During use, pressing the first body 910 realizes the delivery of cleaning fluid.

[0087] In this embodiment, the liquid outlet channel 904 further includes a second liquid outlet section 9042. The liquid blocking component 905 is provided with a drain channel. The two ends of the second liquid outlet section 9042 are respectively connected to the first liquid outlet section 9041 and the drain channel. The extension direction of the drain channel and the extension direction of the second liquid outlet section 9042 are at an angle. In this way, during the process of cleaning liquid spraying, the spraying direction of the cleaning liquid is adjusted to avoid the cleaning liquid being sprayed towards the user.

[0088] like Figures 3 to 5 As shown, in the second embodiment provided in this application, the first body 910 and the second body 920 are detachably connected to allow the cleaning fluid receiving cavity 301 to communicate with or be separated from the mixing cavity 901. The liquid outlet channel 904 includes a first liquid outlet section 9041. The cup structure further includes a baffle member 930, which is disposed on the second body 920 and surrounds the liquid outlet of the first liquid outlet section 9041. At least a portion of the inner wall surface of the first body 910 is fitted with the outer wall surface of the baffle member 930 so that the first body 910 and the second body 920 are interlocked. Through the baffle member 930, the cleaning fluid receiving structure 300 and the mixing cavity 901 are precisely connected, while ensuring the sealing performance of the cup structure. At the same time, the baffle member 930 blocks the outflowing cleaning fluid to prevent leakage. The cleaning fluid in the cleaning fluid receiving structure 300 of this application can flow accurately into the mixing chamber 901, while the engagement of the first body 910 and the second body 920 strengthens the structural integrity of the cup structure. The user installs the cleaning fluid receiving structure 300 onto the second body 920, ensuring proper alignment between the cleaning fluid receiving structure 300 and the outlet channel 904 through the guidance of the enclosure component 930. Then, the first body 910 and the second body 920 are engaged to form a complete cup structure. During use, such as... Figure 4In the indicated state, the first body 910 is inverted, and the cup structure can be flipped 180° to rotate the first body 910 to the bottom of the second body 920. After pressing the second body 920, the cleaning fluid can be directly poured into the mixing chamber 901.

[0089] The second body 920 is provided with a first magnetic component 922; the first end of the first body 910 is provided with a second magnetic component 912. The first magnetic component 922 and the second magnetic component 912 are attracted to each other, so that the first body 910 is fastened to the second body 920. The attraction between the magnetic components simplifies the connection process between the first body 910 and the second body 920, and improves the stability of the connection and the convenience of operation. Users can quickly and accurately fasten the first body 910 and the second body 920. At the same time, the magnetic connection provides additional fastening force to ensure the sealing of the cup structure. Users only need to bring the first end of the first body 910 close to the second body 920, and the first magnetic component 922 and the second magnetic component 912 will naturally attract each other to complete the fastening of the first body 910 and the second body 920. At this time, the first body 910 is upside down on the second body 920. The purpose is to avoid leakage during carrying and to improve the hygiene of the first body 910, and to avoid contamination of the mixing chamber 901.

[0090] A fourth magnetic component 913 is provided at the second end of the first body 910. The first magnetic component 922 and the fourth magnetic component 913 are attracted to each other, allowing the first body 910 to be placed on the second body 920. By providing a second magnetic component 912 and a fourth magnetic component 913 at the first and second ends of the first body 910 respectively, which attract each other to the first magnetic component 922 on the second body 920, the first body 910 can remain stable in both inverted and upright states without the need for additional fixing measures.

[0091] During use, simply remove the first body 910 from the second body 920, then inject the cleaning solution into the mixing chamber 901 using the cleaning solution containing structure 300. After injection or rinsing, the first body 910 can be placed upright on the second body 920, with the base 914 of the first body 910 adhering to the second body 920. The first body 910 is fixed by the attraction between the fourth magnetic component 913 and the first magnetic component 922. The first body 910 has a scale line inside, which allows for a direct view of the volume of solution inside the first body 910, making it easy to confirm the amount remaining and the amount of diluent to be added. Alternatively, the first body 910 can be allowed to air dry after rinsing.

[0092] The base 914 is located at the second end of the first body 910, and the fourth magnetic component 913 is located on the base 914.

[0093] In another embodiment of this invention, a liquid-blocking component 905 is provided on the second body 920, and a flow gap 906 communicating with the mixing chamber 901 is provided between the liquid-blocking component 905 and the liquid outlet of the first liquid outlet section 9041. A third magnetic component 9050 is provided on the liquid-blocking component 905; the first body 910 is placed on the liquid-blocking component 905 by the attraction between the third magnetic component 9050 and the fourth magnetic component 913. Specifically, the liquid-blocking component 905 is positioned above the liquid outlet of the first liquid outlet section 9041.

[0094] The connection between the first body 910 and the liquid-retaining component 905 is simplified through the interaction between the magnetic components. This application improves the structural stability and ease of operation of the cup structure, allowing users to easily place the first body 910 on the liquid-retaining component 905 without additional fixing measures. When the user brings the second end of the first body 910 close to the liquid-retaining component 905, the third magnetic component 9050 and the fourth magnetic component 913 are attracted, making the first body 910 stably placed on the liquid-retaining component 905, facilitating subsequent adjustment of the cleaning fluid dosage. Compared to... Figure 4 In the indicated state, the first body 910 is rotated 180° so that the base 914 of the first body 910 is placed on the liquid-blocking component 905, and the fourth magnetic component 913 is disposed on the base 914. The first body 910 is fixed by the third magnetic component 9050 and the fourth magnetic component 913.

[0095] like Figure 6 and Figure 7As shown, in the third embodiment provided in this application, the first body 910 and the second body 920 are an integral structure. The second body 920 is disposed on the side of the first body 910. The mixing chamber 901 is disposed within the first body 910. The mounting cavity 903 is disposed within the second body 920 and is disposed on the side of the mixing chamber 901. The cleaning fluid containing structure 300 is disposed within the mounting cavity 903 and is movably disposed along the extending direction of the mounting cavity 903. The connecting part 909 is disposed on the bottom wall surface of the mounting cavity 903. By disposing the cleaning fluid containing structure 300 within the mounting cavity 903, the flow rate of the cleaning fluid is controlled by the movement of the cleaning fluid containing structure 300. Simultaneously, the cleaning fluid is mixed with the liquid in the mixing chamber 901 through the liquid outlet channel 904. The liquid outlet channel 904 includes a first liquid outlet section 9041 and a second liquid outlet section 9042 that are interconnected. The first liquid outlet section 9041 extends in the same direction as the mounting cavity 903, and the second liquid outlet section 9042 extends horizontally. The second liquid outlet section 9042 is located at the bottom of the second body 920. The cleaning liquid flows into the first body 910 after passing through the first liquid outlet section 9041 and the second liquid outlet section 9042. Users can adjust the dosage of the cleaning liquid as needed to form a mouthwash of suitable concentration. According to the required dosage of cleaning liquid, the user moves the cleaning liquid receiving structure 300 within the mounting cavity 903. The cleaning liquid flows into the mixing cavity 901 through the liquid outlet channel 904 and mixes with water to form mouthwash. Specifically, the dosage of liquid dispensed by the cleaning liquid receiving structure 300 with each press is limited, so that the amount of water added can be determined based on the number of presses to dilute the mouthwash to a suitable concentration.

[0096] The cleaning fluid containing structure 300 also includes a capsule shell assembly 310, which is movably disposed within the mounting cavity 903. A second positioning portion 380 is provided on the capsule shell assembly 310. A first positioning portion 907 is also provided on the side wall of the mounting cavity 903, extending along the extending direction of the mounting cavity 903. At least a portion of the second positioning portion 380 is inserted into the first positioning portion 907. The capsule shell assembly 310 drives the second positioning portion 380 to move within the first positioning portion 907, thereby limiting the travel distance of the cleaning fluid containing structure 300. Through the cooperation of the first positioning portion 907 and the second positioning portion 380, precise control of the travel distance of the cleaning fluid containing structure 300 is achieved, avoiding inaccurate cleaning fluid dosage caused by excessive squeezing or positional deviation. This application improves the accuracy of cleaning fluid dosage control, ensuring that the ideal concentration of mouthwash is obtained every time it is used. When the user moves the cleaning fluid container structure 300, the second positioning part 380 moves within the first positioning part 907, restricting further movement of the cleaning fluid container structure 300 and thus controlling the dosage of the cleaning fluid. Preferably, the second positioning part 380 is a protruding rib, and the first positioning part 907 is a groove. The protruding rib is slidably disposed within the groove. By restricting the movement of the cleaning fluid container structure 300 by the groove wall, bias pressure is avoided.

[0097] like Figures 8 to 10 As shown, in the fourth embodiment provided in this application, the first body 910 and the second body 920 are an integral structure. The second body 920 is disposed on the side of the first body 910. The mixing chamber 901 is disposed within the first body 910, the mounting cavity 903 is disposed within the second body 920, and the cleaning fluid containing structure 300 is disposed within the mounting cavity 903. A first pushing block 390 is disposed on the cleaning fluid containing structure 300. The cup structure further includes a pushing component 940, disposed on the cup body 900. The pushing component 940 is movably disposed relative to the cup body 900 and is connected to the first pushing block 390. The pushing component 940 pushes the first pushing block 390 to move, so that the first pushing block 390 drives the cleaning fluid containing structure 300 to move along the extension direction of the mounting cavity 903, so that the mixing chamber 901 and the cleaning fluid containing cavity 301 are connected or separated. Preferably, the pushing component 940 and the first pushing block 390 are slidably connected.

[0098] The pushing assembly 940 includes: a second pushing block 941, wherein the first pushing block 390 and the second pushing block 941 are wedge-shaped blocks; an operating handle 942, wherein the second pushing block 941 is disposed on the operating handle 942, and the operating handle 942 is disposed opposite to the cup body 900; and a connecting component 943, which is respectively connected to the cup body 900 and the operating handle 942, wherein at least a portion of the connecting component 943 is elastically disposed. Preferably, the connecting component 943 includes a spring, and the operating handle 942 is movably disposed in a direction approaching or away from the cup body 900. When the operating handle 942 moves toward the cup body 900, it moves against the elastic force of the spring, and at the same time causes the second pushing block 941 to push the first pushing block 390 upward, so that the mixing chamber 901 communicates with the cleaning liquid receiving chamber 301 for cleaning liquid dispensing operation. After dispensing is completed, the operating handle 942 moves away from the cup body 900 under the elastic restoring force of the spring, so that the mixing chamber 901 and the cleaning liquid receiving chamber 301 are separated.

[0099] The connecting component 943 also includes a limiting post and a limiting protrusion. The limiting protrusion is set on the limiting post. The operating handle 942 is provided with a sleeve with a strip-shaped hole. The sleeve is fitted onto the limiting post, and the limiting protrusion is inserted into the strip-shaped hole. The limiting protrusion and the strip-shaped hole are in clearance fit. When the operating handle 942 moves back and forth, the limiting protrusion abuts against the hole walls at both ends of the strip-shaped hole, thereby limiting the movement stroke of the operating handle 942 and ensuring that the operating handle 942 will not detach from the cup body.

[0100] An air cavity 960 is provided between the operating handle 942 and the cup body 900, and the air cavity 960 is connected to the external environment of the cup body 900. Since the operating handle 942 needs to reciprocate, there is a gap between the operating handle 942 and the cup body 900 when the operating handle 942 is in the initial position, and the air cavity 960 is connected to the external environment through the gap.

[0101] Furthermore, a notch 908 is provided on the cup body 900. After the operating handle 942 is engaged with the cup body 900, an operating hole 950 communicating with the air cavity 960 is formed at the notch 908, which facilitates the disassembly and assembly of the operating handle 942.

[0102] The first push block 390 is provided with an air guide hole 313. The design of the push assembly 940, especially the configuration of the second push block 941, the first push block 390, the operating handle 942, the connecting part 943, the air cavity 960, and the air guide hole, provides the following beneficial effects: When the operating handle 942 is pressed by an external force, the second push block 941 moves with the operating handle 942. Since both the first push block 390 and the second push block 941 are wedge-shaped blocks, and their contact surfaces form an inclined plane, the second push block 941 can directly transmit force to the first push block 390 through its wedge-shaped surface. This causes the first push block 390 to push the cleaning fluid into the mixing chamber 901. Specifically, within the mounting cavity 903, it drives the capsule shell assembly 310 and the piston assembly 330 to generate relative movement, thereby compressing the cleaning fluid. This direct power transmission mechanism ensures that the piston assembly 330 can respond quickly when the operating handle 942 is pressed, improving the squeezing efficiency of the cleaning fluid. The presence of the air cavity 960 ensures that when the operating handle 942 is pressed, air can enter the cleaning fluid containing structure from the outside through the air cavity 960, compensating for the volume change caused by the squeezing out of the cleaning fluid and maintaining the pressure balance inside the capsule. This air conditioning mechanism avoids obstruction of the cleaning fluid flow due to a drop in internal pressure, ensuring smooth transmission of the cleaning fluid. An air guide hole is provided on the first push block 390, allowing external air to replenish the cleaning fluid containing structure while the cleaning fluid is being squeezed, further balancing the pressure difference between the inside and outside of the capsule. This helps prevent backflow caused by the pressure difference after the cleaning fluid is squeezed, ensuring unidirectional transmission of the cleaning fluid and enhancing the reliability of the system. The elastic design of the connecting component 943 allows the operating handle 942 to automatically reset when no external force is applied, simultaneously driving the second push block 941 back to its initial position. At the same time, the first push block 390 returns to its initial position under its own weight and the action of the first elastic element 350. This elastic reset mechanism not only simplifies the operation process and reduces the difficulty of operation for users, but also ensures that the piston assembly 330 will not exert unnecessary pressure on the cleaning fluid when not in use, thus extending the service life of the cleaning fluid container. The operating handle 942 is positioned opposite the cup body 900 and maintains a certain distance from it, forming a space that is easy to grip. This design allows users to intuitively feel the movement of the piston assembly 330 during operation, while also providing a comfortable grip and enhancing the user's operating experience.

[0103] In this embodiment, the capsule shell assembly 310 and the first push block 390 are an integral structure, or the capsule shell assembly 310 has a connector at its bottom, which is connected to the capsule shell assembly 310. The first push block 390 is disposed on the connector, which has a clearance structure that communicates with the air guide hole 313 on the first push block 390. The connector is a sleeve structure, and the clearance structure is preferably a clearance hole to ensure that the air pressure chamber 302 is connected to the ambient air pressure.

[0104] In this embodiment, the operating handle 942 is provided with an anti-slip textured structure or flexible pad that matches the palm or fingers to prevent the user from slipping when holding the handle.

[0105] In this embodiment, the liquid outlet channel 904 includes a first liquid outlet section 9041 and a second liquid outlet section 9042 that are interconnected. The liquid blocking component 905 is provided with a drain channel. The two ends of the second liquid outlet section 9042 are respectively connected to the first liquid outlet section 9041 and the drain channel. The extension direction of the drain channel and the extension direction of the second liquid outlet section 9042 are at an angle. In this way, during the process of cleaning liquid spraying, the spraying direction of the cleaning liquid is adjusted to avoid the cleaning liquid being sprayed towards the user.

[0106] Specifically, such as Figure 11 As shown, the cleaning fluid containing structure 300 includes: a cleaning fluid containing cavity 301 for storing cleaning fluid, which is connected to a mixing cavity 901; a piston assembly 330 is disposed within the cleaning fluid containing cavity 301, and the cleaning fluid containing cavity 301 and the piston assembly 330 are movably disposed relative to each other, so that the cleaning fluid in the cleaning fluid containing cavity 301 is squeezed into the mixing cavity 901 by the piston assembly 330. By utilizing the movement of the piston assembly 330 within the cleaning fluid containing cavity 301, the amount of cleaning fluid squeezed out is precisely controlled, ensuring the mixing ratio with the liquid in the mixing cavity 901. This application improves the accuracy of cleaning fluid dosage control while simplifying the structure of the cleaning fluid containing structure 300, facilitating manufacturing and maintenance. The user operates the piston assembly 330, causing it to move within the cleaning fluid containing cavity 301, where the cleaning fluid is squeezed and flows into the mixing cavity 901 through a connecting channel, where it mixes with water to form mouthwash.

[0107] In the cleaning fluid containing structure 300, the piston assembly 330 is threaded, plugged in, or snapped into the connecting part 909. The connecting part 909 includes a protruding block, and the piston assembly 330 is preferably plugged into the protruding block. Specifically, the cross-sectional area of ​​the flow section of the outlet channel 904 is larger than that of the flow section of the injection channel 333. At the same time, the end of the piston assembly 330 is sleeved on the protruding block, and a sealing ring is provided between the piston assembly 330 and the protruding block. In this way, by utilizing the difference between the cross-sectional areas of the flow section of the outlet channel 904 and the flow section of the injection channel 333, the flow rate of the cleaning fluid can be adjusted on the one hand, and the sealing ring can also be used to prevent the cleaning fluid from leaking on the other hand.

[0108] The cup structure also includes an operating unit 902, which is movably positioned relative to the cup body 900. The operating unit 902 is connected to the cleaning fluid containing structure 300 or the cup body 900, and moves the cleaning fluid containing structure 300 or the cup body 900 via the operating unit 902. Specifically, when the operating unit 902 is mounted on the cup body 900, it is connected to the piston assembly 330 via the cup body 900. This direct or indirect connection between the operating unit 902 and the cleaning fluid containing structure 300 or the piston assembly 330 allows the user to directly control the displacement of the cleaning fluid containing structure 300 or the piston assembly 330 simply by moving the operating unit 902. This simplifies the cleaning fluid dispensing process, eliminating the need for the user to directly contact or apply force to the cleaning fluid containing structure 300 or the piston assembly 330, thus improving operational convenience and user experience. The movable nature of the operating unit 902 allows the user to intuitively perceive the direct correlation between operation and cleaning fluid output. The pressing or pulling action of the operating part 902 is directly converted into the displacement of the cleaning fluid receiving structure 300 or the piston assembly 330. This direct force transmission makes the user operation more intuitive and easier to master the correct operating method. The mechanical connection between the operating part 902 and the cleaning fluid receiving structure 300 or the piston assembly 330 ensures that the force applied by the user can be accurately converted into the output of cleaning fluid. This direct connection helps to achieve quantitative squeezing of cleaning fluid. According to the user's pressing force and stroke on the operating part 902, the output of cleaning fluid can be controlled, thereby ensuring that the amount of cleaning fluid used in each cleaning is consistent, improving the predictability and consistency of the cleaning effect. The position design and mobility of the operating part 902 provide the user with a more comfortable operating point, avoiding direct action on the cup body 900 or other internal components, which may result in poor feel or difficult operation due to structural limitations or material hardness. The position and movement of the operating part 902 provide a more ergonomic operating interface, reducing discomfort during operation. The connection between the operating unit 902 and the cleaning fluid containing structure 300 or the piston assembly 330 avoids structural instability or damage that may be caused by directly applying force to these internal components. Through the indirect control of the operating unit 902, the cleaning fluid containing structure 300 or the piston assembly 330 can be driven more accurately and safely, maintaining the integrity and stability of the internal structure and extending the service life of the cup structure.

[0109] The cup body 900 also includes a mounting cavity 903; the cleaning fluid containing structure 300 further includes: a capsule shell assembly 310, disposed within the mounting cavity 903 and slidably connected to the inner wall of the mounting cavity 903; an operating part 902 connected to the capsule shell assembly 310; a cleaning fluid containing cavity 301 disposed within the capsule shell assembly 310; a piston cavity 311 disposed within the cleaning fluid containing cavity 301; and a piston assembly 330 disposed within the piston cavity 311. The operating part 902 drives the capsule shell assembly 310 to move relative to the piston assembly 330, so that when the mixing cavity 901 is connected to the cleaning fluid containing cavity 301, the piston assembly 330 squeezes the cleaning fluid in the piston cavity 311 into the mixing cavity 901. The relative movement of the capsule shell assembly 310 and the piston assembly 330, through the simple mechanical connection of the operating part 902, allows for precise control of the process of the cleaning fluid in the piston cavity 311 being squeezed into the mixing cavity 901. When the user operates the operating unit 902, its action is directly translated into the movement of the piston inside the cleaning fluid containing structure 300, thereby squeezing the cleaning fluid. This direct connection ensures the controllability and precision of the cleaning fluid output, improving the consistency of the cleaning effect. The connection between the operating unit 902 and the capsule shell assembly 310 allows the user to indirectly control the piston assembly 330 through the external operating unit 902 without directly contacting or operating it. This design improves the intuitiveness and convenience of operation; the user can intuitively feel the squeezing of the cleaning fluid through the movement of the operating unit 902, making operation simpler and reducing the difficulty of operation. The design of the capsule shell assembly 310 slidingly connected to the inner wall of the mounting cavity 903 of the cup body 900 provides stable support for the piston assembly 330 during operation. This means that when the user operates the operating unit 902 to squeeze the cleaning fluid, the piston assembly 330 can move smoothly within the piston cavity 311, avoiding problems such as uneven or inability to squeeze the cleaning fluid due to internal structural instability, ensuring the long-term stability and reliability of the cleaning fluid containing structure 300. The capsule shell assembly 310 and piston assembly 330 are indirectly controlled by the operating unit 902, avoiding damage to the internal precision components from direct force. For example, directly pressing the cleaning fluid reservoir 300 may cause deformation or damage, while applying force through the operating unit 902 allows for safer and more accurate control of the cleaning fluid extrusion, protecting the integrity and long-term usability of the cleaning fluid reservoir 300 and other internal components. The sliding connection between the capsule shell assembly 310 and the mounting cavity 903 ensures precise positioning of the cleaning fluid reservoir 300 within the cup body 900. This connection method not only simplifies the installation process of the cleaning fluid reservoir 300 but also improves its stability within the cup body 900, preventing uneven cleaning fluid extrusion caused by capsule misalignment or loosening during use.

[0110] Preferably, the operating part 902 is a pressing surface or a pressing protrusion provided on the capsule shell assembly 310.

[0111] The piston assembly 330 is provided with a liquid injection channel 333, the two ends of which are connected to the piston chamber 311 and the mixing chamber 901, respectively. The cleaning fluid in the piston chamber 311 flows into the mixing chamber 901 through the liquid injection channel 333. The liquid injection channel 333 ensures that the cleaning fluid flows smoothly from the piston chamber 311 into the mixing chamber 901 when the piston assembly 330 moves, achieving precise mixing of the cleaning fluid and water. This application improves the efficiency of the cleaning fluid containing structure 300 while reducing its complexity, facilitating user operation and maintenance. The user operates the piston assembly 330, causing the cleaning fluid in the piston chamber 311 to flow into the mixing chamber 901 through the liquid injection channel 333, where it mixes with water to form mouthwash.

[0112] The piston assembly 330 includes: a piston rod 332, one end of which is connected to the cup body 900, and the other end of which is inserted into the piston chamber 311; a liquid injection channel 333 is disposed within the piston rod 332; and a first elastic member 350, sleeved on the piston rod 332, one end of which is connected to the cup body 900, and the other end of which is connected to the capsule shell assembly 310. The first elastic member 350 is elastically configured to push the capsule shell assembly 310 away from the piston assembly 330 by its elastic restoring force, thereby separating the mixing chamber 901 from the cleaning fluid receiving chamber 301. The piston assembly 330 is automatically reset using the elastic force of the first elastic member 350, ensuring that the cleaning fluid receiving structure 300 returns to its initial position after each use, facilitating future use. This application improves the automation level of the cleaning fluid receiving structure 300, simplifies user operation, and ensures precise control of the cleaning fluid dosage. The user operates the piston assembly 330 to move the piston rod 332 within the piston chamber 311, and the cleaning fluid flows into the mixing chamber 901 through the injection channel 333. After use, the elastic restoring force of the first elastic element 350 pushes the capsule shell assembly 310, causing the piston assembly 330 to return to its initial position, ready for the next use.

[0113] The piston rod 332 is provided with a second through hole 3322, which communicates with the injection channel 333. The cleaning fluid containing structure 300 also includes a sealing element 370, which is disposed in the piston cavity 311 and sleeved on the piston rod 332. The capsule shell assembly 310 drives the sealing element 370 to move relative to the piston rod 332 to block or avoid the second through hole 3322. By moving the sealing element 370 on the piston rod 332, the opening and closing of the second through hole 3322 is controlled, thereby precisely controlling the extrusion volume of the cleaning fluid. This application improves the accuracy of cleaning fluid dosage control while ensuring the sealing performance of the cleaning fluid containing structure 300 and preventing cleaning fluid leakage. The user operates the capsule shell assembly 310, which moves the seal 370. When the seal 370 blocks the second through hole 3322, the cleaning liquid cannot be squeezed out. When the seal 370 avoids the second through hole 3322, the cleaning liquid flows into the mixing chamber 901 through the injection channel 333 and mixes with water to form mouthwash.

[0114] The capsule shell assembly 310 is provided with a first through hole 312, the two ends of which are respectively connected to the piston chamber 311 and the cleaning fluid receiving chamber 301. The cleaning fluid receiving structure 300 also includes a first one-way valve 360, at least a portion of which is disposed within the first through hole 312. The cleaning fluid in the receiving chamber 301 flows into the piston chamber 311 through the first one-way valve 360. The first one-way valve 360 ​​controls the flow of cleaning fluid from the receiving chamber 301 to the piston chamber 311, preventing reverse flow and ensuring stable internal pressure of the cleaning fluid receiving structure 300. This application improves the efficiency and safety of the cleaning fluid receiving structure 300, avoiding waste and leakage of cleaning fluid. The user operates the piston assembly 330, causing the cleaning fluid in the receiving chamber 301 to flow into the piston chamber 311 through the first one-way valve 360, and then into the mixing chamber 901 through the injection channel 333, where it mixes with water to form mouthwash.

[0115] The cleaning fluid containing structure 300 further includes: a movable member 320, movably disposed within the capsule shell assembly 310; a cleaning fluid containing cavity 301 disposed between the inner wall surface 3201 of the movable member 320 and the inner wall surface of the capsule shell assembly 310; and a pressure chamber 302 disposed between the outer wall surface 3202 of the movable member 320 and the inner wall surface of the capsule shell assembly 310; and a vent 313 disposed on the capsule shell assembly 310, communicating with the pressure chamber 302, which in turn communicates with the ambient air pressure of the capsule shell assembly 310. By moving the movable member 320 within the capsule shell assembly 310, the amount of cleaning fluid squeezed out of the cleaning fluid containing cavity 301 is controlled. Simultaneously, the pressure difference between the inside and outside of the capsule shell assembly 310 is adjusted using the pressure chamber 302 and the vent 313, ensuring the normal operation of the cleaning fluid containing structure 300. This application improves the efficiency and safety of the cleaning fluid receiving structure 300, while simplifying the operation process. Users only need to operate the movable part 320 to squeeze out the cleaning fluid. The user operates the movable part 320 to move it within the capsule shell assembly 310, squeezing out the cleaning fluid in the cleaning fluid receiving cavity 301. The fluid flows into the mixing cavity 901 through the injection channel 333, where it mixes with water to form mouthwash. At the same time, the air pressure cavity 302 is connected to the external ambient air pressure through the air guide hole 313, adjusting the pressure difference inside and outside the capsule shell assembly 310 to ensure the normal operation of the cleaning fluid receiving structure 300. During the use of the cleaning fluid containing structure 300, the piston assembly 330 is fixed on the cup body 900, and the capsule shell assembly 310 is movable relative to the piston assembly 330. When the capsule shell assembly 310 or the piston assembly 330 is pressed, the piston rod 332 moves toward the bottom of the piston chamber 311, increasing the hydraulic pressure in the piston chamber 311. Under pressure, the cleaning fluid is squeezed into the injection channel 333, and then flows into the mixing chamber 901 through the outlet channel 904, completing one injection. During this process, the capsule shell assembly 310 squeezes the first elastic member 350, compressing the first elastic member 350. After the injection is completed, the user releases the capsule shell assembly 310. Under the action of the elastic restoring force of the first elastic member 350, the capsule shell assembly 310 is pushed to move toward the initial position. As the cleaning fluid in the cleaning fluid containing chamber 301 decreases, the hydraulic pressure decreases. At this time, the movable part 320 moves under the push of the air pressure in the air pressure chamber 302, thereby achieving the effect of completely squeezing out the cleaning fluid.

[0116] This utility model also provides a dental flosser, such as Figures 12 to 29As shown, the device includes a cleaning fluid containing structure 300 and a housing 100. The housing 100 has a water storage cavity 101 and a liquid outlet 102 connected to the water storage cavity 101. The liquid outlet 102 is located at the bottom of the water storage cavity 101. The bottom of the housing 100 has a capsule containing cavity 103. The oral cleaning fluid containing structure 300 has an oral cleaning fluid containing cavity 301 and is detachably inserted into the capsule containing cavity 103.

[0117] The oral cleaning fluid receiving structure is installed within the capsule receiving cavity 103 of the oral irrigator and includes a capsule shell assembly 310, a movable member 320, a piston assembly 330, and a connecting shell 340. The movable member 320 is movably disposed within the capsule shell assembly 310, and the oral cleaning fluid receiving cavity 301 is formed between the inner wall of the movable member 320 and the inner wall of the capsule shell assembly 310. The capsule shell assembly 310 also has a piston cavity 311, which communicates with the oral cleaning fluid receiving cavity 301 and is also connected to the outlet 102 of the oral irrigator. The piston assembly 330 is slidably disposed within the capsule receiving cavity 103 of the oral irrigator. Inside the piston chamber 311; the connecting housing 340 is provided with a sliding chamber 341, and the capsule housing assembly 310 is slidably disposed in the sliding chamber 341; when the capsule housing assembly 310 slides inward along the sliding chamber 341 under the action of external force, the piston assembly 330 slides toward the piston chamber 311 to spray the oral cleaning fluid in the piston chamber 311 out along the outlet 102 of the oral irrigator; when the capsule housing assembly 310 returns to the initial position, the movable part 320 moves toward the piston assembly 330 under the action of atmospheric pressure and the hydraulic pressure difference in the oral cleaning fluid receiving chamber 301.

[0118] With the above structure, when in use, pressing the capsule shell assembly 310 causes the capsule shell assembly 310 and the movable part 320 to move towards the sliding cavity 341 along the direction of force. At this time, the piston assembly 330 slides towards the piston cavity 311, increasing the pressure in the oral cleaning fluid receiving cavity 301. The oral cleaning fluid flows from the oral cleaning fluid receiving cavity 301 into the piston cavity 311, and then flows into the water storage cavity 101 along the outlet 102. The operation is simple. When the capsule shell assembly 310 is reset, the piston assembly 330 slides away from the piston cavity 311, and the pressure in the oral cleaning fluid receiving cavity 301 decreases. Atmospheric pressure drives the movable part 320 to move inward along the axis of the oral cleaning fluid receiving structure 300 to maintain the pressure in the oral cleaning fluid receiving cavity 301.

[0119] In this embodiment, the oral cleaning fluid containing structure 300 further includes a first elastic member 350, the first end of which abuts against the capsule shell assembly 310, and the second end of which abuts against the inner wall of the sliding cavity 341. With the above-described structure, when in use, pressing the capsule shell assembly 310 causes it to slide within the sliding cavity 341 of the connecting shell 340, thereby causing the piston assembly 330 to slide towards the piston cavity 311. At this time, the first elastic element 350 deforms under force, and the oral cleaning fluid in the oral cleaning fluid receiving cavity 301 flows out. When the user releases the capsule shell assembly 310, the first elastic element 350 resets, driving the capsule shell assembly 310 back to its initial position. Under atmospheric pressure, the movable element 320 moves inward along the axis of the oral cleaning fluid receiving structure 300. The sliding cavity 341 of the connecting shell 340 allows the capsule shell assembly 310 to reciprocate more smoothly, making user operation easier and more convenient. Furthermore, using the connecting shell 340 better connects the oral cleaning fluid receiving structure 300 to the shell 100 and protects the various components therein. The first elastic element 350 can reset the capsule shell assembly 310, making operation simpler.

[0120] In this embodiment, the connecting shell 340 is provided with a connecting channel 342. The first end of the connecting channel 342 is connected to the piston chamber 311, and the second end of the connecting channel 342 is connected to the liquid outlet 102. With the above structure, when in use, pressing the capsule shell assembly 310 causes the piston assembly 330 to slide towards the piston chamber 311, increasing the pressure in the oral cleaning liquid receiving chamber 301. The oral cleaning liquid flows from the oral cleaning liquid receiving chamber 301 into the piston chamber 311, passes through the connecting channel 342, and then flows along the liquid outlet 102 into the water storage chamber 101. The operation is simple, the oral cleaning liquid flow channel is unobstructed, and the product structure is stable.

[0121] In this embodiment, the piston assembly 330 includes a fixed rod 331 and a piston rod 332. The fixed rod 331 abuts against the housing 100 and is inserted into the piston cavity 311, while the piston rod 332 is slidably inserted into the piston cavity 311. With this structure, during use, pressing the capsule housing assembly 310 causes the capsule housing assembly 310 and the movable member 320 to move along the direction of force. At this time, the fixed rod 331 slides towards the piston cavity 311, and the piston rod 332 moves with the capsule housing assembly 310 towards the fixed rod 331 until the piston rod 332 abuts against the fixed rod 331. Then, the piston rod 332 continues to slide towards the piston cavity 311 with the fixed rod 331, increasing the pressure inside the piston cavity 311. The oral cleaning fluid inside the piston cavity 311 flows out under pressure. The fluid enters through the connecting channel 342 and flows into the water storage chamber 101 via the outlet 102. When the user releases the capsule shell assembly 310, the first elastic element 350 resets, driving the capsule shell assembly 310 back to its initial position. The fixing rod 331 slides away from the piston chamber 311, and atmospheric pressure drives the movable element 320 to move inward along the axis of the oral cleaning fluid receiving structure 300. The pressure in the oral cleaning fluid receiving chamber 301 drives the oral cleaning fluid to flow into the piston chamber 311, and the piston rod 332 slides away from the piston chamber 311. The piston rod 332 can slide relative to the piston chamber 311 under the action of pressure and the fixing rod 331, which can adjust the pressure in the piston chamber 311 and the oral cleaning fluid receiving chamber 301, thereby allowing the oral cleaning fluid to flow into the water storage chamber 101 via the connecting channel 342 and the outlet 102.

[0122] In this embodiment, the fixed rod 331 is provided with a fixed rod channel 3311, and the piston rod 332 is provided with a piston rod channel 3321. The piston rod 332 is connected to the piston cavity 311, the piston rod channel 3321, the connecting channel 342, and the liquid outlet 102 in sequence. With the above structure, when the fixed rod 331 slides toward the piston cavity 311, the piston rod 332 moves toward the fixed rod 331 along with the capsule shell assembly 310 until the piston rod 332 abuts against the fixed rod 331. At this time, the piston rod 332 continues to slide toward the piston cavity 311 along with the fixed rod 331, the pressure in the piston cavity 311 increases, and the oral cleaning fluid in the piston cavity 311 flows into the connecting channel 342 along the piston rod channel 3321 and the fixed rod channel 3311 under pressure, and finally flows out along the liquid outlet 102.

[0123] The fixed rod channel 3311 includes a first channel segment 3312 and a second channel segment 3313 that are interconnected. The piston rod 332 is disposed in the first channel segment 3312, and the second channel segment 3313 is connected to the connecting channel 342. The piston rod 332 is provided with a piston rod channel 3321, and the two ends of the piston rod channel 3321 are respectively connected to the piston chamber 311 and the second channel segment 3313.

[0124] The piston chamber 311 and the oral cleaning fluid receiving chamber 301 are connected through the first through hole 312. The oral cleaning fluid receiving structure also includes a limiting block 334, which is disposed in the piston chamber 311 and located on the side of the first through hole 312. The piston rod 332 contacts the limiting block 334 to limit the movement stroke of the piston rod 332.

[0125] In this embodiment, the oral cleaning fluid containing structure 300 further includes a first one-way valve 360. The capsule shell assembly 310 is provided with a first through hole 312, which allows the oral cleaning fluid containing cavity 301 to communicate with the piston cavity 311. The first one-way valve 360 ​​is disposed in the first through hole 312 and is used to allow the oral cleaning fluid to flow unidirectionally from the oral cleaning fluid containing cavity 301 to the piston cavity 311. With the above structure, during use, when the fixed rod 331 slides toward the piston cavity 311, the piston rod 332 moves toward the fixed rod 331 along with the capsule shell assembly 310 until the piston rod 332 abuts against the fixed rod 331. At this time, the piston rod 332 continues to slide toward the piston cavity 311 along with the fixed rod 331, the first one-way valve 360 ​​closes, and the pressure in the piston cavity 311 increases, so that the oral cleaning fluid flows into the connecting channel 342 along the piston rod channel 3321 and the fixed rod channel 3311, and finally flows out along the outlet 102. When the user releases the capsule shell assembly 310, the first elastic element 350 drives the capsule shell assembly 310 to reset, and atmospheric pressure drives the movable element 320 to move inward along the axis of the oral cleaning fluid receiving structure 300. The first one-way valve 360 ​​opens, and the pressure in the oral cleaning fluid receiving cavity 301 drives the oral cleaning fluid to flow into the piston cavity 311.

[0126] In this embodiment, the oral cleaning fluid containing structure 300 further includes a sealing element 370, and the piston rod 332 is also provided with a second through hole 3322. The second through hole 3322 allows the piston cavity 311 to communicate with the piston rod channel 3321. The sealing element 370 is slidably sleeved on the piston rod 332 and covers or opens the second through hole 3322. With the above structure, in use, when the fixing rod 331 slides toward the piston cavity 311, the piston rod 332 moves toward the fixing rod 331 along with the capsule shell assembly 310 until the piston rod 332 abuts against the fixing rod 331. At this time, the piston rod 332 continues to slide toward the piston cavity 311 along with the fixing rod 331, the sealing element 370 moves relative to the piston rod 332, and the second through hole 3322 opens to allow the oral cleaning fluid to pass through the second through hole 3322 and enter the piston rod channel 3321.

[0127] In this embodiment, the capsule shell assembly 310 is further provided with an air guide hole 313. A pressure chamber 302 is formed between the inner wall of the movable member 320 and the inner wall of the capsule shell assembly 310. The air guide hole 313 is used to connect the pressure chamber 302 and the external atmosphere. With the above structure, the air guide hole 313 can connect the external atmosphere and the pressure chamber 302. When the pressure in the oral cleaning fluid receiving chamber 301 decreases, the atmospheric pressure can drive the movable member 320 to move inward, ensuring the pressure inside the oral cleaning fluid receiving chamber 301 is stable, thereby making it easier for the oral cleaning fluid to enter the water storage chamber 101 under the action of the piston assembly 330.

[0128] In this embodiment, the bottom of the housing 100 is provided with a capsule receiving cavity 103, and the oral cleaning fluid receiving structure 300 is detachably inserted into the capsule receiving cavity 103. With the above-described structure, the user can easily insert the oral cleaning fluid receiving structure 300 into the capsule receiving cavity 103 during use, and can freely replace the oral cleaning fluid receiving structure 300 when the oral cleaning fluid in the oral cleaning fluid receiving cavity 301 is depleted. Furthermore, for the sake of stability, oral cleaning fluid receiving structures are typically designed to be narrower at the top and wider at the bottom. Positioning the oral cleaning fluid receiving structure 300 at the bottom of the housing 100 (generally referring to the portion below the vertical midline of the housing 100) allows for the use of a larger volume oral cleaning fluid receiving structure 300, thereby extending the product's lifespan, reducing the frequency of replacing the oral cleaning fluid receiving structure 300, and improving the user experience.

[0129] In this embodiment, the surface of the oral cleaning fluid receiving structure 300 is provided with a slot 303, which is used to allow the snap-fit ​​component 400 inside the water flosser to snap into place. With this structure, during use, the oral cleaning fluid receiving structure 300 is inserted into the capsule receiving cavity 103, and the snap-fit ​​end of the snap-fit ​​component 400 snaps into the slot 303, effectively fixing the oral cleaning fluid receiving structure 300 and making the product structure more stable. When removing the oral cleaning fluid receiving structure 300, the snap-fit ​​end of the snap-fit ​​component 400 is detached from the slot 303, separating the oral cleaning fluid receiving structure 300 from the capsule receiving cavity 103, making it convenient for the user to disassemble the oral cleaning fluid receiving structure 300 and simplifying the operation.

[0130] The housing 100 has a water storage chamber 101 and a liquid outlet 102 connected to the water storage chamber 101. The liquid outlet 102 is located at the bottom of the water storage chamber 101. The bottom of the housing 100 has a capsule receiving chamber 103.

[0131] The oral cleaning fluid containing structure 300 described above has an oral cleaning fluid containing cavity 301 inside. The oral cleaning fluid containing structure 300 is detachably inserted into the capsule containing cavity 103. The axis of the force direction of the oral cleaning fluid containing structure intersects or projects into the vertical axis of the shell.

[0132] It also includes a pumping assembly 200, which is disposed inside the housing 100. The suction port 201 of the pumping assembly 200 extends to the bottom of the water storage chamber 101 near the outlet 102. The pumping assembly 200 is used to draw liquid and spray the liquid out along the nozzle 210.

[0133] With the above-described structure, during use, the user holds the housing 100 and simultaneously presses the oral cleaning liquid receiving structure 300 located at the bottom of the housing 100. The oral cleaning liquid receiving structure 300 is subjected to force, and the oral cleaning liquid within it is injected into the bottom of the water storage chamber 101. The pumping component 200 then operates, with its suction port 201 extending to the bottom of the water storage chamber 101, allowing it to draw out liquid with a higher concentration of oral cleaning liquid from the bottom of the water storage chamber 101, resulting in better product cleaning. For stability, oral irrigators are typically designed to be narrower at the top and wider at the bottom; the oral cleaning liquid receiving structure 300 is designed accordingly. The placement at the bottom of the housing 100 allows for the use of a larger volume oral cleaning solution container 300, thereby extending the product's lifespan, reducing the frequency of replacing the oral cleaning solution container 300, and making it more convenient to use. Furthermore, since the axis of the force direction of the oral cleaning solution container 300 intersects or projects into the vertical axis of the housing 100, no greater gripping force is required when pressing the oral cleaning solution container 300. This makes it easier and more convenient for users to press the oral cleaning solution container 300, allowing them to hold the product with one hand and press the oral cleaning solution container 300 with their palm.

[0134] In this embodiment, the snap-fit ​​assembly 400 includes a snap-fit ​​member 410, a pressing member 420, and a second elastic member 430. The housing 100 is provided with a button hole 104. The pressing member 420 is disposed in the button hole 104. The first end of the second elastic member 430 abuts against the pressing member 420, and the second end of the second elastic member 430 abuts against the snap-fit ​​member 410. The elasticity of the second elastic member 430 drives the snap-fit ​​member 410 to be inserted into the slot 303. The pressing member 420 is used to drive the snap-fit ​​member 410 to be disengaged from the slot 303 under external pressure. With the above structure, when in use, pressing the pressing member 420 causes the second elastic member 430 to deform, and the pressing member 420 drives the locking member 410 to move outward. The locking end of the locking member 410 is disengaged from the slot 303, which can easily separate the oral cleaning liquid containing structure 300 from the capsule containing cavity 103. When the user releases the pressing member 420, the second elastic member 430 resets, drives the locking member 410 to move inward, and the locking end of the locking member 410 is engaged with the slot 303. This allows the oral cleaning liquid containing structure 300 to be stably connected to the capsule containing cavity 103, improving the stability of the product and making disassembly and assembly convenient.

[0135] In this embodiment, the snap-fit ​​assembly 400 further includes a transmission member 440. The first end of the transmission member 440 is rotatably connected to the pressing member 420, the middle part of the transmission member 440 is rotatably connected to the housing 100, and the second end of the transmission member 440 is rotatably connected to the snap-fit ​​member 410. With the above structure, when in use, pressing the pressing member 420 causes the second elastic member 430 to deform, and the pressing member 420 pushes the transmission member 440 inward to rotate around its middle part. The second end of the transmission member 440 drives the snap-fit ​​member 410 to move outward, so that the snap-fit ​​end of the snap-fit ​​member 410 is disengaged from the slot 303. When the user releases the pressing member 420, the second elastic member 430 resets, drives the snap-fit ​​member 410 to move inward, and at the same time, the snap-fit ​​member 410 drives the transmission member 440 to rotate around its middle part. The transmission member 440 pushes the pressing member 420 to move outward, so that the pressing member 420 resets to its initial position.

[0136] In this embodiment, two snap-fit ​​components 400 are included, which are disposed within the housing 100 and located on both sides of the capsule receiving cavity 103. Through this structural arrangement, the two symmetrically arranged snap-fit ​​components 400 can respectively snap into the slots 303 on both sides of the oral cleaning liquid receiving structure 300, which enhances the stability of the product structure and prevents accidental contact by the user. The user must simultaneously press the pressing parts 420 of both snap-fit ​​components 400 to separate the oral cleaning liquid receiving structure 300 from the capsule receiving cavity 103.

[0137] In this embodiment, a detachment component 500 is also included. The detachment component 500 includes a third elastic member 510 and a detachment protrusion 520. An opening 105 is provided on the upper part of the inner wall of the capsule receiving cavity 103. The first end of the third elastic member 510 abuts against the shell 100, and the second end of the third elastic member 510 abuts against the detachment protrusion 520. The abutting end of the detachment protrusion 520 passes through the opening 105 and abuts against the upper surface of the oral cleaning liquid receiving structure 300. With the above structure, when the snap-fit ​​member 410 of the snap-fit ​​assembly 400 snaps into the slot 303, the third elastic member 510 drives the disengagement protrusion 520 to move toward the oral cleaning fluid receiving structure 300, and the disengagement protrusion 520 abuts against the surface of the oral cleaning fluid receiving structure 300; when the snap-fit ​​member 410 of the snap-fit ​​assembly 400 is disengaged from the slot 303, the third elastic member 510 drives the disengagement protrusion 520 to move toward the oral cleaning fluid receiving structure 300, and the disengagement protrusion 520 pushes the oral cleaning fluid receiving structure 300 so that the oral cleaning fluid receiving structure 300 is detached from the capsule receiving cavity 103, making it convenient for the user to replace the oral cleaning fluid receiving structure 300.

[0138] In this embodiment, the third elastic element 510 includes two springs. The housing 100 is provided with two spring receiving grooves 121, and the two springs are respectively inserted into the two spring receiving grooves 121. The second ends of the two springs respectively abut against the two ends of the detachment protrusion 520 and are symmetrically arranged along the axis of the capsule receiving cavity 103. With the above structure, the two springs abut against the two ends of the detachment protrusion 520, which allows the detachment protrusion 520 to stably pass through the opening 105. Moreover, the spring receiving grooves 121 can allow the springs to be stably inserted, restrict the deformation direction of the springs, and improve the stability of the product.

[0139] In this embodiment, the housing 100 includes an upper housing 110 and a bottom housing 120. The bottom housing 120 is detachably connected to the upper housing 110, and a water storage cavity 101 is formed between the upper housing 110 and the bottom housing 120. A capsule receiving cavity 103 is disposed in the bottom housing 120. With the above structure, the upper housing 110 and the bottom housing 120 are detachably connected, allowing the user to remove the bottom housing 120 and open the water storage cavity 101, facilitating cleaning of the water storage cavity 101 and ensuring its cleanliness, thereby protecting the user's oral health.

[0140] In this embodiment, a first sealing ring 130 is also included. A first sealing groove 122 is provided on the upper edge of the bottom shell 120. The first sealing ring 130 is inserted into the first sealing groove 122, and the outer surface of the first sealing ring 130 abuts against the inner wall of the upper shell 110. With the above structure, when in use, the bottom shell 120 is installed on the upper shell 110. At this time, the outer surface of the first sealing ring 130 abuts against the inner wall of the upper shell 110, and the inner surface and the upper and lower surfaces of the first sealing ring 130 abut against the inner wall of the first sealing groove 122. This can increase the sealing performance of the product, prevent the liquid in the water storage cavity 101 from leaking out, and improve the sealing performance of the product.

[0141] In this embodiment, a locking assembly 600 is also included. The locking assembly 600 includes a locking member 610 and a fourth elastic member 620. The first end of the fourth elastic member 620 abuts against the bottom shell 120, and the second end of the fourth elastic member 620 abuts against the locking member 610. The locking member 610 is locked to the upper shell 110. Through the above-described structure, the elastic force of the fourth elastic member 620 drives the locking member 610, causing the locking member 610 to lock to the upper shell 110, thereby improving the stability of the connection between the upper shell 110 and the bottom shell 120.

[0142] In this embodiment, the upper housing 110 is provided with a locking groove 111, and the locking part 611 of the locking member 610 is detachably engaged with the locking groove 111. With the above structure, the elastic force of the fourth elastic member 620 drives the locking member 610, so that the locking part 611 of the locking member 610 is engaged with the locking groove 111, making the connection between the upper housing 110 and the bottom housing 120 stable.
