[0078] 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.

[0079] Please refer to Figures 10 to 12This utility model provides an oral cleaning fluid containing structure, including: a capsule shell assembly 310, in which an oral cleaning fluid containing cavity 301 is provided, the oral cleaning fluid containing cavity 301 being used to communicate with a target outlet 102; and a piston assembly 330, disposed in the oral cleaning fluid containing cavity 301. The capsule shell assembly 310 and the piston assembly 330 are movably disposed relative to each other, so that the cleaning fluid in the oral cleaning fluid containing cavity 301 is forced out of the target outlet 102 by the piston assembly 330.

[0080] With the above-described structure, the piston assembly 330 or the capsule shell assembly 310 can be moved relative to each other by pressing. During this process, the piston assembly 330 gradually squeezes the internal space of the oral cleaning fluid receiving cavity 301, increasing its pressure. Under the pressure difference between the oral cleaning fluid receiving cavity 301 and the target outlet 102, the cleaning fluid in the oral cleaning fluid receiving cavity 301 is squeezed out to the target outlet 102. In this way, when using the oral cleaning fluid receiving structure, there is no need to use a pump to extract the cleaning fluid. It can be achieved using only the above structure, which not only reduces the overall weight of the structure but also simplifies the operation steps and makes it more convenient to use.

[0081] Specifically, the piston assembly 330 includes a piston rod 332, which has an injection channel 333. The two ends of the injection channel 333 are connected to the oral cleaning fluid receiving cavity 301 and the target outlet 102, respectively. The cleaning fluid in the oral cleaning fluid receiving cavity 301 flows into the target outlet 102 through the injection channel 333. This arrangement ensures that during the movement of the piston rod 332, the cleaning fluid in the oral cleaning fluid receiving cavity 301 is directly forced into the injection channel 333, preventing overflow of the cleaning fluid from the oral cleaning fluid receiving cavity 301.

[0082] In a specific implementation, the piston rod 332 is provided with a second through hole 3322 communicating with the injection channel 333. The oral cleaning fluid containing structure also includes a sealing member 370, which is sleeved on the piston rod 332. The sealing member 370 is movably positioned relative to the piston rod 332 to block or avoid the second through hole 3322. When cleaning fluid is not needed, the piston rod 332 or the sealing member 370 can be moved to prevent leakage of cleaning fluid from the oral cleaning fluid containing cavity 301.

[0083] Furthermore, the capsule shell assembly 310 also includes a piston chamber 311, which is connected to the oral cleaning fluid receiving chamber 301 and the target liquid outlet 102, respectively; the piston assembly 330 is disposed within the piston chamber 311. This arrangement facilitates the miniaturization and weight reduction of the piston assembly 330, allowing liquid dispensing to be achieved with a small stroke of the piston chamber 311.

[0084] To maintain the pressure difference between the piston chamber 311 and the target outlet 102, the oral cleaning fluid containing structure further includes: a first one-way valve 360, disposed between the piston chamber 311 and the oral cleaning fluid containing chamber 301, through which the oral cleaning fluid flows into the piston chamber 311; the capsule shell assembly 310 further includes a first through hole 312, disposed between the oral cleaning fluid containing chamber 301 and the piston chamber 311, with the first one-way valve 360 ​​disposed within the first through hole 312. The first one-way valve 360 ​​allows the cleaning fluid to flow unidirectionally from the oral cleaning fluid containing chamber 301 into the piston chamber 311, preventing backflow of the cleaning fluid within the piston chamber 311.

[0085] In specific implementation, the oral cleaning fluid containing structure further includes: a connecting shell 340, a sliding cavity 341 provided within the connecting shell 340, a capsule shell assembly 310 slidably disposed within the sliding cavity 341, a piston assembly 330 connected to the connecting shell 340, a connecting channel 342 provided within the connecting shell 340, and both ends of the connecting channel 342 communicating with the oral cleaning fluid containing cavity 301 and the target outlet 102, respectively; and a first elastic member 350, one end of which abuts against the inner wall of the sliding cavity 341, and the other end of which abuts against the capsule shell assembly 310. Preferably, the first elastic member 350 is a spring.

[0086] The capsule shell assembly 310 also includes a piston cavity 311 communicating with the oral cleaning fluid receiving cavity 301. The piston assembly 330 includes: a fixing rod 331, one end of which is connected to the inner wall of the sliding cavity 341 and the other end is inserted into the piston cavity 311; and a piston rod 332, one end of which is slidably connected to the fixing rod 331 and the other end is inserted into the piston cavity 311.

[0087] The fixed rod 331 is provided with a fixed rod channel 3311, which 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.

[0088] 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.

[0089] The capsule shell assembly 310 includes a receiving cavity 3101, and the oral cleaning fluid receiving structure further includes a movable member 320 disposed within the receiving cavity 3101, and the oral cleaning fluid receiving cavity 301 disposed between the inner wall surface 3201 of the movable member 320 and the receiving cavity 3101; the movable member 320 is movably disposed relative to the capsule shell assembly 310.

[0090] A pressure chamber 302 is provided between the outer wall surface 3202 of the movable part 320 and the accommodating cavity 3101; an air guide hole 313 is provided on the capsule shell assembly 310, and the pressure chamber 302 is connected to the ambient air through the air guide hole 313.

[0091] 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 connected to the target outlet 102 of the oral irrigator. The piston assembly 330 is slidably disposed within the capsule shell assembly 340. Inside the piston chamber 311; the connecting housing 340 is provided with a sliding cavity 341, and the capsule housing assembly 310 is slidably disposed in the sliding cavity 341; when the capsule housing assembly 310 slides inward along the sliding cavity 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 along the target 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 cavity 301.

[0092] 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 target 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.

[0093] 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.

[0094] 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 target 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 fluid receiving chamber 301. The oral cleaning fluid flows from the oral cleaning fluid receiving chamber 301 into the piston chamber 311, passes through the connecting channel 342, and then flows along the target liquid outlet 102 into the water storage chamber 101. The operation is simple, the oral cleaning fluid flow channel is unobstructed, and the product structure is stable.

[0095] 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. Under pressure, the oral cleaning fluid inside the piston cavity 311 flows in. The connecting channel 342 then flows into the water storage chamber 101 along the target 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 along the connecting channel 342 and the target outlet 102.

[0096] 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 target liquid outlet 102 in sequence. With the above structure, in 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 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 target liquid outlet 102.

[0097] 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 target 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] This utility model also provides an oral cleaning device, including: a device body, a mixing chamber provided inside the device body, and a target outlet 102 provided inside the mixing chamber; an oral cleaning fluid containing structure 300 connected to the device body, wherein the oral cleaning fluid containing cavity 301 inside the oral cleaning fluid containing structure 300 is connected to the mixing chamber through the target outlet 102; wherein, the oral cleaning fluid containing structure 300 is the oral cleaning fluid containing structure of the above embodiment.

[0103] like Figures 1 to 18 The present invention also provides a water flosser, including an oral cleaning fluid containing structure 300 as described in the above embodiment and a housing 100. The housing 100 is provided with a water storage chamber 101 and a liquid outlet 102 communicating with 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 is provided with a capsule containing chamber 103. The oral cleaning fluid containing structure 300 is provided with an oral cleaning fluid containing chamber 301 and is detachably inserted into the capsule containing chamber 103.

[0104] The oral irrigator 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 in liquid and spray the liquid out along the nozzle 210.

[0105] The housing 100 includes an upper housing 110 and a bottom housing 120, the bottom housing 120 being detachably connected to the upper housing 110, a water storage cavity 101 being disposed between the upper housing 110 and the bottom housing 120, and a capsule receiving cavity 103 being disposed within the bottom housing 120.

[0106] Specifically, the housing 100 is provided with a water storage cavity 101 and a target liquid outlet 102 connected to the water storage cavity 101. The target liquid outlet 102 is located at the bottom of the water storage cavity 101, and the bottom of the housing 100 is provided with a capsule receiving cavity 103.

[0107] 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.

[0108] 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 target liquid outlet 102. The pumping assembly 200 is used to draw liquid and spray the liquid out along the nozzle 210.

[0109] 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.

[0110] 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.

[0111] 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, in use, pressing the pressing member 420 causes the second elastic member 430 to deform, pushing 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, driving the snap-fit ​​member 410 to move inward. Simultaneously, the snap-fit ​​member 410 drives the transmission member 440 to rotate around its middle part, and the transmission member 440 pushes the pressing member 420 outward, so that the pressing member 420 returns to its initial position.

[0112] In this embodiment, the snap-fit ​​assembly 400 includes two components, 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 ​​assemblies 400 can respectively snap into the slots 303 on both sides of the oral cleaning liquid receiving structure 300. This 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 ​​assemblies 400 to separate the oral cleaning liquid receiving structure 300 from the capsule receiving cavity 103.

[0113] In this embodiment, a detachment component 500 is also included. The detachment component 500 includes a third elastic element 510 and a detachment protrusion 520.

The first end of the third elastic element 510 abuts against the housing 100, and the second end of the third elastic element 510 abuts against the detachment protrusion 520. The abutting end of the detachment protrusion 520 protrudes 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.

[0114] In this embodiment, the third elastic element 510 includes two springs, and the housing 100 is provided with two spring receiving grooves 121. The two springs are respectively inserted into the two spring receiving grooves 121, and 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, limit the deformation direction of the springs, and improve the stability of the product.

[0115] 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. The capsule receiving cavity 103 is disposed in the bottom housing 120. With this 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 and ensuring the cleanliness of the water storage cavity 101, thereby protecting the user's oral health.

[0116] 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.

[0117] 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 structural arrangement, 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.

[0118] 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. Through the above structure, the elastic force of the fourth elastic member 620 drives the locking member 610, causing the locking part 611 of the locking member 610 to engage with the locking groove 111, thus ensuring a stable connection between the upper housing 110 and the bottom housing 120.

[0119] In this embodiment, the bottom shell 120 is provided with a slot 123, and the detachment portion 612 of the locking member 610 protrudes through the slot 123. The detachment portion 612 of the locking member 610 is used by the user to press it, so that the locking portion 611 of the locking member 610 is detached from the locking groove 111. With the above structure, when in use, pressing the detachment portion deforms the fourth elastic member 620, and the locking portion of the locking member 610 is detached from the locking groove 111, allowing the user to detach the bottom shell 120 from the upper shell 110; when the user releases the detachment portion, the fourth elastic member 620 returns to its original position, pushing the locking portion of the locking member 610 to engage with the locking groove 111, so that the upper shell 110 and the bottom shell 120 are stably connected.

[0120] In this embodiment, a second one-way valve 700 is also included. The housing 100 extends downward along the edge of the target outlet 102 to form a first abutment block 106. A protruding second abutment block 127 is provided inside the housing 100. The second abutment block 127 is disposed facing the first abutment block 106. The second one-way valve 700 is provided with an abutment platform 701. The first abutment block 106 abuts against the upper surface of the abutment platform 701, and the second abutment block 127 abuts against the lower surface of the abutment platform 701, so as to limit the second one-way valve 700 between the first abutment block 106 and the second abutment block 127. The second one-way valve 700 is used to allow oral cleaning fluid to flow unidirectionally into the water storage chamber 101 along the target outlet 102. With the above-described structure, during use, the second one-way valve 700 allows the oral cleaning fluid to flow unidirectionally into the water storage chamber 101 along the installation channel and the target outlet 102, preventing the liquid in the water storage chamber 101 from flowing back into the oral cleaning fluid receiving structure 300, thus ensuring the concentration of the oral cleaning fluid in the oral cleaning fluid receiving structure 300 and ensuring the cleaning efficacy of the oral cleaning fluid. The first abutting block 106 abuts against the upper surface of the abutting platform 701, and the second abutting block 127 abuts against the lower surface of the abutting platform 701, effectively fixing the second one-way valve 700, improving product stability, and also enhancing the product's sealing performance to prevent leakage of oral cleaning fluid, etc. Furthermore, the first abutting block 106 and the second abutting block 127 are interference-fitted against the surface of the abutting platform 701, further enhancing the product's sealing performance and preventing water leakage.

[0121] In this embodiment, the second abutment block 127 is provided with an insertion groove 126, and the second one-way valve 700 is provided with an insertion block 702. The insertion block 702 extends downward along the lower surface of the abutment platform 701 and is inserted into the insertion groove 126. With the above structure, when in use, the insertion block 702 is inserted into the insertion groove 126. At this time, the outer surface of the insertion block 702 is in contact with the inner wall surface of the insertion groove 126, which can effectively limit the insertion block 702, thereby limiting the installation position of the second one-way valve 700. The product structure is more stable. At the same time, the outer surface of the insertion block 702 is in contact with the inner wall surface of the insertion groove 126, which can further enhance the sealing performance of the product.

[0122] In this embodiment, the insert block 702 is provided with a limiting platform 703, and the inner sidewall end face of the insert groove 126 abuts against the limiting platform 703. With the above structure, during use, the insert block 702 is inserted along the insert groove 126 until the inner sidewall end face of the insert groove 126 abuts against the limiting platform 703, reaching the installation position. The limiting platform 703 can effectively limit the insertion depth, making the product connection more stable. At the same time, the inner sidewall end face of the insert groove 126 can also support the limiting platform, thereby allowing the inner side of the lower surface of the first abutting block 106 to fit against the upper surface of the abutting platform 701 with an interference fit, further improving the sealing performance and stability of the product.

[0123] In this embodiment, the upper surface of the bottom shell 120 protrudes upward near the target liquid outlet 102 to form a protrusion 128, and the target liquid outlet 102 is located at the top of the protrusion 128. With this structure, the target liquid outlet 102 is positioned at the top of the protrusion 128, increasing the contact area between the oral cleaning fluid exiting the target liquid outlet 102 and the water. This allows the oral cleaning fluid to quickly diffuse into the water in the water storage chamber 101, resulting in better and more stable product cleaning performance.

[0124] In this embodiment, the upper surface of the bottom shell 120 is inclined, and a suction space is formed between the protrusion 128 and the lowest side of the upper surface of the bottom shell 120. The suction port 201 of the pumping assembly 200 extends into the suction space. With this structure, during use, as the water in the water storage chamber 101 decreases, water flows into the suction space under gravity. The extension of the suction port 201 of the pumping assembly 200 into the suction space effectively and thoroughly removes the liquid from the suction space, improving the suction efficiency of the pumping assembly 200, preventing liquid accumulation, and increasing liquid utilization efficiency.

[0125] In this embodiment, a transparent observation window is provided at the bottom of the side wall of the upper housing 110, allowing the user to observe the liquid level in the water storage chamber 101. With this structure, the user can observe the liquid level in the water storage chamber 101 through the observation window, enabling them to understand the product's operating status and add water as needed, thus improving the user experience. Simultaneously, it prevents the pumping assembly 200 from running dry, extending the product's service life.

[0126] In this embodiment, the observation window includes a front observation window unit 1131 and a rear observation window unit 1132, which are respectively disposed on the front and rear sides of the upper housing 110.

Preferably, the front observation window unit 1131 is approximately a trapezoid with rounded corners, and the rear observation window unit 1132 is also approximately a trapezoid with rounded corners. The ratio of the area of ​​the front observation window unit 1131 to the area of ​​the rear observation window unit 1132 is approximately 1.2-1.8, and the front observation window unit 1131 and rear observation window unit 1132 are disposed opposite to each other.

[0127] In this embodiment, a liquid injection cap 140 is also included. The upper housing 110 is provided with a liquid injection port 107, which is connected to the water storage chamber 101. The liquid injection cap 140 is detachably fitted onto the liquid injection port 107. With the above structure, water can be injected into the water storage chamber 101 through the liquid injection port 107 by opening the liquid injection cap 140, making it convenient for users to add water at any time. When in use, the liquid injection cap 140 is closed onto the liquid injection port 107 to prevent water from flowing out and improve the product's sealing performance.

[0128] In this embodiment, the upper housing 110 is provided with a pivot hole 114 near the injection port 107, and the connecting end of the injection cap 140 is provided with a pivot shaft 141. The pivot shaft 141 is rotatably inserted into the pivot hole 114, so that the injection cap 140 can be detachably closed to the injection port 107. With the above structure, rotating the injection cap 140 detaches it from the injection port 107, allowing water to be injected into the water storage chamber 101 through the injection port 107. In use, rotating the injection cap 140 to the closed position closes the injection port 107, preventing water leakage and improving the product's sealing performance.

[0129] In this embodiment, a second sealing ring 150 is also included. The injection cap 140 has a protruding sealing block 142 on the side facing the upper housing 110. The sealing block 142 has a second sealing groove 143. The second sealing ring 150 is inserted into the second sealing groove 143, and the outer surface of the second sealing ring 150 abuts against the edge of the injection port 107. With this structure, when the injection cap 140 is closed over the injection port 107, the outer surface of the second sealing ring 150 abuts against the edge of the injection port 107, and the inner surface and upper and lower surfaces of the second sealing ring 150 abut against the second sealing groove 143. This further improves the sealing performance between the injection cap 140 and the injection port 107, preventing water from flowing out along the gap between the injection cap 140 and the injection port 107.

[0130] In this embodiment, the upper housing 110 is recessed inward near the injection port 107 to form a receiving groove 108. When the injection cap 140 is closed on the injection port 107, the injection cap 140 is basically accommodated within the receiving groove 108. With this structure, when the injection cap 140 is closed on the injection port 107, the injection cap 140 is basically accommodated within the receiving groove 108. At this time, the outer surface of the injection cap 140 is basically flush with the upper housing 110. This makes the product more aesthetically pleasing and also prevents the injection cap 140 from opening due to user scratches, thus improving product stability.

[0131] In this embodiment, the free end of the liquid filling cap 140 is bent outward to form a toggle part 144. When the liquid filling cap 140 is closed on the liquid filling port 107, there is a gap between the toggle part 144 and the receiving groove 108. With the above structure, when opening the liquid filling cap 140, the user inserts their finger into the gap between the toggle part 144 and the receiving groove 108, moves the toggle part 144 outward, and then rotates the liquid filling cap 140, making it convenient for the user to open the liquid filling cap 140.

[0132] In this embodiment, the injection cap 140 is provided with a first latch 145 near the sealing block 142, and the injection port 107 is provided with a second latch 117 at its edge. The first latch 145 is engaged with the second latch 117. With the above structure, when the injection cap 140 is closed on the injection port 107, the first latch 145 is engaged with the second latch 117, thereby connecting the free end of the injection cap 140 to the upper housing 110, preventing the rotation of the injection cap 140, and improving the stability of the product.

[0133] In this embodiment, a control board 800 is also included. The control board 800 is disposed within the upper housing 110, and the pumping assembly 200 is electrically connected to the control board 800. The upper housing 110 is provided with a charging port 109, and the charging terminal within the charging port 109 is electrically connected to the control board 800. Through the above structural arrangement, the charging terminal within the charging port 109 can connect the control board 800 and an external power source, enabling charging of the product and improving its battery life.

[0134] In this embodiment, a charging cover 160 is also included, which is detachably fitted onto the charging port 109. With the above structure, during charging, the charging cover 160 is opened to allow the charger's output end to be inserted into the charging port 109 for charging; during use, the charging cover 160 is closed onto the charging port 109 to prevent water, dust, and other impurities from entering the charging port 109, thus improving product safety.

[0135] In this embodiment, the upper housing 110 is provided with an insertion slot 115 near the edge of the charging port 109, the insertion slot 115 being used for inserting a user's finger. By setting the above structure and providing the insertion slot 115, it is convenient for the user to insert their finger into the insertion slot 115, thereby opening the charging cover 160 and facilitating user operation.

[0136] In this embodiment, the surface of the upper housing 110 is provided with a friction grip portion 116, and the friction grip portion 116 is provided with friction texture. Through the above-described structure, the friction texture at the friction grip portion 116 can increase the coefficient of friction, making the user's grip on the product more stable, and at the same time, making the product's appearance more aesthetically pleasing.

[0137] In this embodiment, the upper housing 110 is narrower at the top and wider at the bottom, and the friction grip portion 116 is disposed on the upper part of the upper housing 110. With the above-described structure, the friction grip portion 116 is disposed on the upper part of the upper housing 110, where the thickness of the upper housing 110 is moderate, making it convenient for the user to grip.

[0138] In this embodiment, the bottom shell 120 is provided with a drainage groove 129, which is connected to the internal space of the bottom shell 120. With the above structure, during use, the drainage groove 129 can allow water accumulated inside the bottom shell 120 to flow out, ensuring the dryness of the product's interior and preventing bacterial growth; preferably, the drainage groove 129 is located at the bottom of the bottom shell 120.

[0139] like Figures 19 to 29The present invention also provides a mouthwash cup, including a cup body 900 and an oral cleaning liquid containing structure 300. A mixing chamber 901 is provided in the cup body 900. The oral cleaning liquid containing structure 300 is connected to the cup body 900 and communicates with the mixing chamber 901. The oral cleaning liquid containing structure 300 is the oral cleaning liquid containing structure 300 of the above embodiment.

[0140] The mouthwash cup also includes a connecting part 909, disposed on the cup body 900, with a liquid outlet channel 904 within the connecting part 909. The oral cleaning liquid containing structure 300 is connected to the connecting part 909, and the two ends of the liquid outlet channel 904 are respectively connected to the oral cleaning liquid containing structure 300 and the mixing chamber 901. This design allows the cleaning liquid in the oral cleaning liquid containing structure 300 to flow smoothly into the mixing chamber 901, mixing with water or other liquids to form mouthwash. The principle is based on the tight fit between the oral cleaning liquid containing structure 300 and the connecting part 909, ensuring accurate delivery of the cleaning liquid. The mouthwash cup 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 inserts the oral cleaning liquid containing structure 300 into the connecting part 909, and then operates a specific mechanism of the mouthwash cup, such as a button or rotating mechanism, to cause the cleaning liquid in the oral cleaning liquid containing structure 300 to flow through the liquid outlet channel 904 into the mixing chamber 901, mixing with water for rinsing.

[0141] The oral cleaning solution container 300 is detachably connected to the connecting part 909. This detachable connection is designed to facilitate the replacement of the oral cleaning solution container 300, ensuring the mouthwash cup can continuously use different types of cleaning solutions. The mouthwash cup of this application allows for quick replacement of the oral cleaning solution container 300 according to personal preference or oral health needs, improving the versatility and personalization of the mouthwash cup. When the cleaning solution in the oral cleaning solution container 300 is depleted, the user can easily detach it from the connecting part 909, replace it with a new oral cleaning solution container 300, and then reconnect it to the connecting part 909 to replenish the cleaning solution.

[0142] Specifically, the oral cleaning fluid container structure 300 and the connecting part 909 can be threaded or plugged in, making it convenient to replace the oral cleaning fluid container structure 300.

[0143] The mouthwash cup also includes: a mounting cavity 903 disposed within the cup body 900; a connecting part 909 disposed on the inner wall of the mounting cavity 903; and at least a portion of the oral cleaning fluid containing structure 300 disposed within the mounting cavity 903. The mounting cavity 903 is positioned above, below, or to the side of the mixing chamber 901. The principle of this design is to optimize the flow path of the cleaning fluid and improve mixing efficiency by rationally arranging the oral cleaning fluid containing structure 300 and the mixing chamber 901. The cleaning fluid in the oral cleaning fluid containing structure 300 can mix with the liquid in the mixing chamber 901 more quickly and evenly, forming high-quality mouthwash. The user places the oral cleaning fluid containing structure 300 into the mounting cavity 903 and operates the mouthwash cup to allow the cleaning fluid in the oral cleaning fluid containing structure 300 to flow into the mixing chamber 901, where it mixes with the pre-existing liquid, thus completing the preparation of the mouthwash.

[0144] A connecting part 909 is disposed on the outer wall surface of the cup body 900, and the oral 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 oral cleaning liquid containing structure 300 outside the cup body 900 for easy observation and replacement, while also avoiding the oral cleaning liquid containing structure 300 occupying the internal space of the mixing chamber 901. The mouthwash cup of this application is partially or entirely made of transparent material, improving the visual transparency of the mouthwash cup and allowing users to intuitively see the state of the oral cleaning liquid containing structure 300, while ensuring the maximum capacity of the mixing chamber 901. Users install the oral 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 oral cleaning liquid containing structure 300 can be directly observed; when replacing the oral cleaning liquid containing structure 300, there is no need 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 the top, side, or bottom surface of the cup body 900, including but not limited to. 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 oral cleaning liquid containing structure 300 can quickly dispense liquid. The detachable connection of the first body 910 and the second body 920 facilitates replacement and use of the oral 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 mouthwash cup. Users can easily adjust the position of the oral 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 oral cleaning liquid containing structure 300.

[0145] The liquid outlet channel 904 includes a first outlet section 9041, with its two ends connected to the oral cleaning liquid containing structure 300 and the mixing chamber 901, respectively. The mouthwash cup 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 in 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. Figure 19 and Figure 20As shown, in the first embodiment of this application, the first body 910 and the second body 920 are slidably disposed relative to each other. The first body 910 is provided with a first guide portion 911, and the second body 920 is provided with a second guide portion 921. The first guide portion 911 and the second guide portion 921 are interlocked to guide the first body 910 when it moves. The cooperation of the first guide portion 911 and the second guide portion 921 ensures the stability and accuracy of the first body 910 and the second body 920 during relative sliding. This application improves the structural stability of the mouthwash cup and the user experience, avoiding shaking or misalignment during sliding. The user adjusts the position of the oral cleaning liquid containing structure 300 by sliding the first body 910 and the second body 920; the interlocking of the first guide portion 911 and the second guide portion 921 ensures smooth and precise sliding. Specifically, the first guide portion 911 is an insertion ring, and the second guide portion 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. 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 oral cleaning fluid receiving cavity 301, squeezing the cleaning fluid in the oral cleaning fluid receiving cavity 301 into the mixing cavity 901. The design of the piston assembly 330 being connected to the first body 910 allows pressing the first body 910 or the second body 920 to directly cause the piston assembly 330 to move relative to the oral cleaning fluid receiving cavity 301. This direct mechanical connection ensures that the pressing action can be efficiently converted into a squeezing process of the cleaning fluid, improving the transmission 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 oral 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 transmission, 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 deviation or loosening during pressing, further improving the stability and precision of the cleaning fluid transfer. This design facilitates the quantitative transfer of the cleaning fluid, ensuring a consistent ratio of cleaning fluid to water in the mixing cavity 901 each time it is used, improving the consistency and predictability of the cleaning effect.

[0146] In this embodiment, the oral cleaning fluid containing structure 300 is connected to the second body 920. To improve the connection stability between the second body 920 and the oral 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 oral 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.

[0147] 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.

[0148] like Figures 21 to 23 As shown, in the second embodiment provided in this application, the first body 910 and the second body 920 are detachably connected; the mouthwash cup also includes: a baffle member 930, disposed on the second body 920, the baffle member 930 surrounding the outlet of the first liquid outlet section 9041; at least a portion of the inner wall surface of the first body 910 is fitted against 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 precise docking of the oral cleaning fluid containing structure 300 and the mixing chamber 901 is achieved, while ensuring the sealing performance of the mouthwash cup. At the same time, the baffle member 930 blocks the outflowing cleaning fluid, preventing leakage. The cleaning fluid in the oral cleaning fluid containing structure 300 of this application can accurately flow into the mixing chamber 901, while the interlocking of the first body 910 and the second body 920 strengthens the structural integrity of the mouthwash cup. The user installs the oral cleaning solution container 300 onto the second body 920, ensuring proper alignment between the oral cleaning solution container 300 and the liquid outlet channel 904 via the guide member 930. Then, the first body 910 and the second body 920 are fastened together to form a complete mouthwash cup structure. During use, as... Figure 22 In the indicated state, the first body 910 is inverted. The mouthwash cup can be flipped 180° and the first body 910 rotated to be below the second body 920. After pressing the second body 920, the cleaning solution can be directly poured into the mixing chamber 901.

[0149] 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, improving the stability of the connection and the ease of operation. Users can quickly and accurately fasten the first body 910 and the second body 920, while the magnetic connection provides additional securing force, ensuring the sealing of the mouthwash cup. 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, completing the fastening of the first body 910 and the second body 920. At this time, the first body 910 is inverted on the second body 920 to prevent leakage during carrying and to improve the hygiene of the first body 910, avoiding contamination of the mixing chamber 901.

[0150] 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.

[0151] During use, simply remove the first body 910 from the second body 920, then inject the oral cleaning solution into the mixing chamber 901 using the oral 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.

[0152] 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.

[0153] 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.

[0154] 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 mouthwash cup, allowing users to easily place the first body 910 on the liquid-retaining component 905 without additional securing 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, stably placing the first body 910 on the liquid-retaining component 905, facilitating subsequent adjustment of the cleaning solution dosage. Compared to... Figure 22 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.

[0155] like Figure 24 and Figure 25As 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, and the cup body 900 further includes: an installation cavity 903 disposed within the second body 920 and on the side of the mixing chamber 901; an oral cleaning fluid containing structure 300 disposed within the installation cavity 903, the oral cleaning fluid containing structure 300 being movably disposed along the extending direction of the installation cavity 903; and a liquid outlet channel 904 disposed at the bottom of the cup body 900, the liquid outlet channel 904 being connected to the oral cleaning fluid containing chamber 301 and the mixing chamber 901 respectively. By disposing of the oral cleaning fluid containing structure 300 within the installation cavity 903, the flow rate of the cleaning fluid is controlled by the movement of the oral cleaning fluid containing structure 300, while the mixing of the cleaning fluid and the liquid in the mixing chamber 901 is achieved 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 oral 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 oral 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.

[0156] The cup body 900 is further provided with a first positioning part 907, and the oral cleaning liquid receiving structure 300 is provided with a second positioning part 380. At least a portion of the second positioning part 380 is inserted into the first positioning part 907. The oral cleaning liquid receiving structure 300 drives the second positioning part 380 to move within the first positioning part 907 until the first positioning part 907 and the second positioning part 380 abut against each other, thereby limiting the movement stroke of the oral cleaning liquid receiving structure 300. Through the cooperation of the first positioning part 907 and the second positioning part 380, precise control of the movement stroke of the oral cleaning liquid receiving structure 300 is achieved, avoiding inaccurate cleaning liquid dosage caused by excessive squeezing or positional displacement. This application improves the accuracy of cleaning liquid dosage control, ensuring that the ideal concentration of mouthwash is obtained every time it is used. When the user moves the oral cleaning liquid receiving structure 300, the second positioning part 380 moves within the first positioning part 907 until the two abut against each other, limiting further movement of the oral cleaning liquid receiving structure 300, thereby controlling the cleaning liquid dosage. Preferably, the second positioning part 380 is a protruding rib, and the first positioning part 907 is a sliding groove. The protruding rib is slidably disposed in the sliding groove. By restricting the groove wall surface, the protruding rib drives the oral cleaning liquid containing structure 300 to move, thus avoiding bias pressure.

[0157] like Figures 26 to 28 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 cup body 900 is also provided with an installation cavity 903, which is disposed within the second body 920. The oral cleaning fluid containing structure 300 is disposed within the installation cavity 903. The oral cleaning fluid containing structure 300 is provided with a first pushing block 390. The mouthwash cup also includes a pushing component 940, which is disposed on the cup body 900. The pushing component 940 is movably disposed relative to the cup body 900. The pushing component 940 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 oral cleaning fluid containing structure 300 to move along the extension direction of the installation cavity 903. Preferably, the pushing component 940 and the first pushing block 390 are slidably connected.

[0158] 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 connected to the cup body 900 and the operating handle 942 respectively, 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 to perform the cleaning liquid dispensing operation. After the dispensing is completed, the operating handle 942 moves away from the cup body 900 under the elastic restoring force of the spring.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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 oral 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 delivery of the cleaning fluid. An air guide hole is provided on the first push block 390, allowing external air to replenish the oral 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 delivery 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 does not exert unnecessary pressure on the cleaning fluid when not in use, thus extending the service life of the oral 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.

[0163] 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.

[0164] 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.

[0165] 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.

[0166] Specifically, such as Figure 29 As shown, the oral cleaning fluid containing structure 300 includes: an oral 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 oral cleaning fluid containing cavity 301, and the oral cleaning fluid containing cavity 301 and piston assembly 330 are movably disposed relative to each other, squeezing the cleaning fluid in the oral cleaning fluid containing cavity 301 into the mixing cavity 901 via the piston assembly 330. By utilizing the movement of the piston assembly 330 within the oral 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 oral cleaning fluid containing structure 300, facilitating manufacturing and maintenance. The user operates the piston assembly 330, causing it to move within the oral cleaning fluid containing cavity 301, squeezing the cleaning fluid and allowing it to flow into the mixing cavity 901 through a connecting channel, where it mixes with water to form mouthwash.

[0167] In the oral cleaning fluid containing structure 300, the piston assembly 330 is threaded, plugged in, or snapped into the connecting part 909, which is a protruding block. Preferably, the piston assembly 330 is plugged into the protruding block. Specifically, the cross-sectional area of ​​the flow channel 904 is larger than that of the flow channel 333. Simultaneously, the end of the piston assembly 330 is fitted onto the protruding block, and a sealing ring is provided between the piston assembly 330 and the protruding block. This difference in cross-sectional area between the flow channel 904 and the flow channel 333 allows for adjustment of the cleaning fluid flow rate and, in conjunction with the sealing ring, prevents leakage of the cleaning fluid.

[0168] The mouthwash cup also includes an operating unit 902, which is movably positioned relative to the cup body 900. The operating unit 902 is connected to the oral cleaning fluid containing structure 300 or the cup body 900, and moves the oral cleaning fluid containing structure 300 or the cup body 900 via the operating unit 902. Specifically, when the operating unit 902 is positioned 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 oral cleaning fluid containing structure 300 or the piston assembly 330 allows the user to directly control the displacement of the oral cleaning fluid containing structure 300 or the piston assembly 330 simply by moving the operating unit 902. This simplifies the process of squeezing the cleaning fluid, eliminating the need for the user to directly contact or apply force to the oral 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 oral cleaning fluid receiving structure 300 or the piston assembly 330. This direct force transmission makes the operation more intuitive for the user and easier to master the correct operating method. The mechanical connection between the operating part 902 and the oral cleaning fluid receiving structure 300 or the piston assembly 330 ensures that the force applied by the user is 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 oral 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 indirect control of the operating unit 902, the oral 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 mouthwash cup.

[0169] The cup body 900 also includes a mounting cavity 903; the oral 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; an oral cleaning fluid containing cavity 301 disposed within the capsule shell assembly 310; a piston cavity 311 disposed within the oral 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 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 squeezing the cleaning fluid in the piston cavity 311 into the mixing cavity 901. When the user operates the operating unit 902, the action is directly translated into the movement of the piston inside the oral cleaning fluid receiving 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 oral cleaning fluid receiving 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 oral cleaning fluid container 300 may cause it to deform or be damaged, while applying force through the operating unit 902 allows for safer and more accurate control of the fluid extrusion, protecting the integrity and long-term usability of the oral cleaning fluid container 300 and other internal components. The sliding connection between the capsule shell assembly 310 and the mounting cavity 903 ensures the precise positioning of the oral cleaning fluid container 300 within the cup body 900. This connection method not only simplifies the installation process of the oral cleaning fluid container 300 but also improves its stability within the cup body 900, preventing uneven fluid extrusion caused by capsule displacement or loosening during use.

[0170] Preferably, the operating part 902 is a pressing surface or a pressing protrusion provided on the capsule shell assembly 310.

[0171] The piston assembly 330 is provided with an 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 injection channel 333. The 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 oral cleaning fluid container structure 300 while reducing its complexity, making it easier for users to operate and maintain. 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 injection channel 333, where it mixes with water to form mouthwash.

[0172] 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 cavity 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, and its elastic restoring force pushes the capsule shell assembly 310 to move away from the piston assembly 330. Utilizing the elastic force of the first elastic member 350, the piston assembly 330 is automatically reset, ensuring that the oral cleaning liquid containing structure 300 returns to its initial position after each use, facilitating future use. This application improves the automation level of the oral cleaning liquid containing structure 300, simplifies user operation, and ensures precise control of the cleaning liquid 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.

[0173] The piston rod 332 is provided with a second through hole 3322, which communicates with the injection channel 333. The oral cleaning fluid containing structure 300 also includes a sealing member 370, which is disposed in the piston cavity 311 and sleeved on the piston rod 332. The capsule shell assembly 310 drives the sealing member 370 to move relative to the piston rod 332 to block or avoid the second through hole 3322. By moving the sealing member 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 oral 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.

[0174] The capsule shell assembly 310 is provided with a first through hole 312, the two ends of which are connected to the piston chamber 311 and the oral cleaning fluid receiving chamber 301, respectively. The oral cleaning fluid receiving structure 300 further includes a first one-way valve 360, at least a portion of which is disposed within the first through hole 312. The oral cleaning fluid 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 oral cleaning fluid receiving chamber 301 to the piston chamber 311, preventing reverse flow and ensuring stable internal pressure of the oral cleaning fluid receiving structure 300. This application improves the efficiency and safety of the oral 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 oral cleaning fluid 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.

[0175] The oral cleaning fluid containing structure 300 further includes: a movable member 320, movably disposed within the capsule shell assembly 310; an oral 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 an air guide hole 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 through the air guide hole 313. By moving the movable member 320 within the capsule shell assembly 310, the amount of cleaning fluid squeezed out of the oral 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 air guide hole 313, ensuring the normal operation of the oral cleaning fluid containing structure 300. This application improves the efficiency and safety of the oral 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, causing it to move within the capsule shell assembly 310. The cleaning fluid in the oral cleaning fluid receiving cavity 301 is squeezed out and flows into the mixing chamber 901 through the injection channel 333, where it mixes with water to form mouthwash. Simultaneously, the air pressure chamber 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 oral cleaning fluid receiving structure 300.

[0176] During the use of the oral 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 oral 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.

[0177] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0178] With the above-described structure, the piston assembly 330 or the capsule shell assembly 310 can be moved relative to each other by pressing. During this process, the piston assembly 330 gradually squeezes the internal space of the oral cleaning fluid receiving cavity 301, increasing its pressure. Under the pressure difference between the oral cleaning fluid receiving cavity 301 and the target outlet 102, the cleaning fluid in the oral cleaning fluid receiving cavity 301 is squeezed out to the target outlet 102. In this way, when using the oral cleaning fluid receiving structure, there is no need to use a pump to extract the cleaning fluid. It can be achieved using only the above structure, which not only reduces the overall weight of the structure but also simplifies the operation steps and makes it more convenient to use.

[0179] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
