Description

Technical Field

[0001] This invention generally relates to the field of personal care technology, and more specifically, to a mouthwash generating structure and a water flosser. Background Technology

[0002] A water flosser, also known as a dental irrigator, is an oral hygiene tool that uses a high-speed water flow to rinse teeth and remove food debris from between teeth, thus achieving a clean teeth effect.

[0003] To further ensure effective teeth cleaning, existing water flossers use mouthwash instead of regular water, typically in two ways: one is to directly insert a capsule containing mouthwash into the capsule chamber, puncture it using a puncture mechanism to allow the mouthwash to flow into the water tank; the other is to directly add a few drops of mouthwash to the water tank. However, both methods require stopping the flossing process to add mouthwash, which is cumbersome and time-consuming, resulting in a poor user experience and failing to meet diverse user needs. Summary of the Invention

[0004] The present invention provides a mouthwash generating structure and a water flosser, which is simple to operate, convenient to use, and provides a good user experience.

[0017] Where d≤h<2d, d≤b<2d.

[0018] In some embodiments, both the first valve and the second valve include a plurality of jaws, wherein the plurality of jaws of the first valve are configured to move toward or away from each other, and the plurality of jaws of the second valve are configured to move toward or away from each other.

[0019] In some embodiments, a sealing gasket is provided on the side of the plurality of jaws of the first valve that are close to each other, for an isolation seal between the storage chamber and the transition chamber; and / or,

[0020] The second valve has a sealing gasket on one side of the plurality of jaws that are close to each other, for sealing the gap between the delivery channel and the transition chamber.

[0021] In some embodiments, a guide portion is provided on one side of the plurality of claws of the first valve that is close to each other, the guide portion being used to guide one of the mouthwash beads; and / or,

[0022] The second valve has a guide portion on one side of the plurality of said claws that are close to each other, the guide portion being used to guide one of said mouthwash beads.

[0023] In some embodiments, the guide portion is a receiving groove with its opening facing the storage chamber, the receiving groove being used to receive at least a portion of one of the mouthwash beads.

[0024] In some embodiments, an acceleration sensor is also included, electrically connected to the switching assembly, the acceleration sensor being configured to detect oscillating acceleration signals to control the opening and closing of the switching assembly.

[0025] In some embodiments, the sensor is a triaxial accelerometer sensor used to identify swaying acceleration along a first direction;

[0026] The first direction is different from the direction of the punch movement.

[0027] In some embodiments, a sealing cover is also included, wherein the storage chamber has an opening, and the sealing cover is detachably connected to the storage chamber and seals the opening.

A storage chamber provides space for mouthwash beads, and a water tank provides space for cleaning water while also providing space for the mouthwash beads to dissolve and mix with the cleaning water. A delivery channel is selectively connected at one end to the storage chamber and at the other end to the water tank, transporting the mouthwash beads from the storage chamber to the water tank. After the user places the mouthwash beads in the storage chamber, if they want to use diluted mouthwash to freshen their breath during rinsing, a switch assembly is configured to activate upon shaking. Simply shaking the water flosser a few times activates the switch assembly, connecting the storage chamber and the delivery channel. The mouthwash beads in the storage chamber automatically fall into the delivery channel and, under its transport, into the water tank. The mouthwash beads dissolve upon contact with water, thus obtaining diluted mouthwash to freshen breath. The mouthwash generating process is time-saving, labor-saving, easy to operate, and relatively fun. Attached Figure Description

[0053] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0054] Current oral irrigators typically have only one water tank for holding cleaning water, preventing the mixing of various cleaning products. When users need to use mouthwash, it must be added separately. For example, a puncture mechanism can be used to break the capsule containing mouthwash, allowing it to flow into the tank, or a few drops can be added directly to the tank. However, these methods require stopping the irrigating process to add mouthwash, making the operation cumbersome and time-consuming, resulting in a poor user experience.

[0055] This embodiment provides a mouthwash generating structure, such as Figure 1 As shown, the mouthwash generating structure includes a storage chamber 1, a water tank 2, and a delivery channel 4. The storage chamber 1 is used to hold mouthwash beads 10; the water tank 2 is used to hold cleaning water. The delivery channel 4 is located between the storage chamber 1 and the water tank 2, and is connected to the water tank 2. A switch assembly 3 is disposed between the storage chamber 1 and the delivery channel 4 for selective connection between the two. That is, one end of the delivery channel 4 is selectively connected to the storage chamber 1 via the switch assembly 3, and the other end is connected to the water tank 2. The switch assembly 3 is configured to open when shaken, for connection between the storage chamber 1 and the delivery channel 4, allowing the mouthwash beads 10 to enter the water tank 2 through the delivery channel 4 and dissolve in the cleaning water to form mouthwash.

[0056] This embodiment provides a mouthwash generating structure. The storage chamber 1 provides a space to hold the mouthwash beads 10, and the water tank 2 provides a space to hold the cleaning water while also providing a space for the mouthwash beads 10 to dissolve and mix with the cleaning water. By setting one end of the delivery channel 4 to be selectively connected to the storage chamber 1 and the other end to the water tank 2, the delivery channel 4 serves to deliver the mouthwash beads 10 in the storage chamber 1 to the water tank 2. After the user places the mouthwash beads 10 into the storage chamber 1, if they want to use diluted mouthwash to freshen their breath during the water flossing process, the switch component 3 is configured to be turned on when shaken. Simply shake the water flosser body a few times to turn on the switch component 3, connecting the storage chamber 1 and the delivery channel 4. The mouthwash beads 10 in the storage chamber 1 will then automatically fall into the delivery channel 4 and fall into the water tank 2 under the conveying action of the delivery channel 4. The mouthwash beads 10 dissolve upon contact with water, thus obtaining diluted mouthwash to achieve the purpose of freshening breath. The process of producing mouthwash is time-saving, labor-saving, easy to operate, and quite fun.

[0057] It should be noted that if the storage chamber 1 is directly above the water tank 2, then the bottom plate of the storage chamber 1 is the top plate of the water tank 2, and the delivery channel 4 is a through hole on the top plate of the water tank 2, through which the mouthwash beads 10 in the storage chamber 1 fall directly into the water tank 2. If there is a certain distance between the storage chamber 1 and the water tank 2, then the delivery channel 4 is a pipe between the storage chamber 1 and the water tank 2, and the length of the pipe is adapted to the height distance between the storage chamber 1 and the water tank 2. In this case, the length of the delivery channel 4 is relatively long, which prolongs the time for water vapor in the water tank 2 to return to the storage chamber 1, thereby reducing the risk of water vapor in the water tank 2 causing the mouthwash beads 10 in the storage chamber 1 to become damp again.

[0058] It should be noted that the switch assembly 3 can be a solenoid valve. A vibration switch that is non-directional and can be triggered at any angle can be selected. When the switch is stationary, it is in the OFF state. When it is subjected to an external force collision that reaches an appropriate vibration force, or when the moving speed reaches an appropriate centrifugal force or eccentric force, the conductive pin will generate an instantaneous conduction (ON) state, which changes the electrical characteristics. When the external force disappears, the electrical characteristics return to the open circuit (OFF) state.

[0059] In one embodiment, the mouthwash generating structure further includes a sealing cap 5, the storage chamber 1 is provided with an opening, and the sealing cap 5 is detachably connected to the storage chamber 1 and the sealing cap 5 is provided at the opening.

[0060] By providing an opening in the storage chamber 1, the user can insert the mouthwash gel 10 through the opening. Since there is a large amount of moisture in the air, if the storage chamber 1 is an open structure, the mouthwash gel 10 may dissolve upon contact with moisture. A sealing cap 5 is detachably connected to the storage chamber 1 and positioned at the opening. When closed, the sealing cap 5 ensures that the entire storage chamber 1 is a sealed structure, effectively isolating it from external moisture and preventing external moisture from entering the storage chamber 1 and dissolving the mouthwash gel 10, thus ensuring the effectiveness of the mouthwash gel 10.

[0061] Understandably, the storage chamber 1 is used to hold multiple mouthwash beads 10. In other words, the internal space of the storage chamber 1 is relatively large, providing space for multiple mouthwash beads 10, allowing users to add multiple mouthwash beads 10 at once, preventing the need to add mouthwash beads 10 every time mouthwash is needed, thus extending the usage time and saving users time from repeated additions.

[0062] If multiple mouthwash beads 10 simultaneously fall into the delivery channel 4 through the switch assembly 3 during a single shaking process, it will not only result in a high concentration of mouthwash and waste resources, but also fail to effectively reduce the need for users to repeatedly add mouthwash beads 10. To solve this problem, such as Figures 1-3 As shown, the switch assembly 3 provided in this embodiment is used for multiple mouthwash beads 10 to enter the delivery channel 4 one by one. With this setting, the switch assembly 3 not only sorts the multiple mouthwash beads 10, but also separates them one by one. Each time the device is shaken, the switch assembly 3 is turned on, allowing only one mouthwash bead 10 to pass through into the delivery channel 4, ensuring that the concentration of mouthwash obtained each time is the same. At the same time, the multiple mouthwash beads 10 added by the user at one time can be used in multiple sessions and can be used multiple times.

[0063] It should be noted that storage chamber 1 is approximately a cuboid structure. The height direction of storage chamber 1 is defined as the first direction, i.e., the vertical direction, and the width direction of storage chamber 1 is defined as the second direction, i.e., the horizontal direction. The first and second directions are perpendicular to each other. The first and second directions only represent spatial directions and have no substantial meaning.

[0064] In one embodiment, such as Figures 4-7 As shown, the switch assembly 3 includes a first valve 31, which is located at the bottom of the storage chamber 1 along a first direction and is used to open and close the outlet of the storage chamber 1.

[0065] Specifically, a first valve 31 is provided at the bottom of the storage chamber 1 along the first direction. The first valve 31 can selectively block the outlet located at the bottom of the storage chamber 1 to realize the opening and closing of the outlet of the storage chamber 1. When the user does not need to use mouthwash, the first valve 31 is closed, and the mouthwash beads 10 can only be temporarily stored in the storage chamber 1 and cannot fall into the conveying channel 4; when the user needs to use mouthwash, the first valve 31 is opened, and the mouthwash beads 10 can fall from the storage chamber 1 into the conveying channel 4.

[0066] In one embodiment, the switching assembly 3 further includes a second valve 32, which is disposed at the top of the conveying channel 4 along the first direction and is used to open and close the inlet of the conveying channel 4.

[0067] A second valve 32 is installed at the top of the conveying channel 4 along the first direction. The second valve 32 can selectively block the inlet at the top of the conveying channel 4 to open and close the inlet of the conveying channel 4. When the user does not need to use mouthwash, the second valve 32 is closed, and the mouthwash beads 10 can only be temporarily stored in the storage chamber 1 or between the first valve 31 and the second valve 32, and cannot fall into the conveying channel 4. When the user needs to use mouthwash, the second valve 32 is opened, and the mouthwash beads 10 can fall from the storage chamber 1 into the conveying channel 4.

[0068] In one embodiment, such as Figures 4-7 As shown, either the first valve 31 or the second valve 32 can be opened.

[0069] If both valves 31 and 32 are opened simultaneously, and both are open, the storage chamber 1 may be connected to the water tank 2 via the conveying channel 4. In this case, water vapor in the water tank 2 may evaporate in the reverse direction and be transferred to the storage chamber 1 via the conveying channel 4, causing the mouthwash beads 10 in the storage chamber 1 to become damp and dissolve. By selectively opening either valve 31 or valve 32—that is, if valve 31 is open, valve 32 is closed; or if valve 31 is closed, valve 32 is open—at least one of the two valves isolates the storage chamber 1 from the conveying channel 4. This ensures that water vapor in the water tank 2 is only temporarily stored in the conveying channel 4, reducing the risk of water vapor entering the storage chamber 1 and thus ensuring that the mouthwash beads 10 in the storage chamber 1 remain dry, guaranteeing the reliability of the mouthwash beads 10. Specifically, valve 31 is opened first, and valve 32 is closed; then valve 31 is closed, and valve 32 is opened.

[0070] In one embodiment, such as Figures 4-7 As shown, a transition chamber 33 is provided between the first valve 31 and the second valve 32, and the transition chamber 33 is used to temporarily store the mouthwash beads 10.

[0071] By providing a transition chamber 33 between the first valve 31 and the second valve 32, the transition chamber 33 serves to temporarily store the mouthwash gel 10, allowing the mouthwash gel 10 to stay in the transition chamber 33 for a short time, thus avoiding the situation where the first valve 31 and the second valve 32 are opened at the same time.

[0072] In one embodiment, the transition chamber 33 is used to temporarily store a mouthwash bead 10.

[0073] By setting a transition chamber 33 to temporarily store a mouthwash gel 10, the transition chamber 33 not only provides a space for the mouthwash gel 10, but also limits the number of mouthwash gel 10, so that only one mouthwash gel 10 can enter the delivery channel 4 through the second valve 32, thereby achieving the purpose of separating the mouthwash gel 10 one by one.

[0074] In one embodiment, the height of the transition chamber 33 is h along the first direction, the diameter of the mouthwash beads 10 is d, and the minimum width of the transition chamber 33 is b along the second direction. The first and second directions are perpendicular to each other. Wherein, d≤h<2d and d≤b<2d.

[0075] If d > h, meaning the diameter d of the mouthwash gel 10 is greater than the height h of the transition chamber 33, then the height of the transition chamber 33 is relatively small, and the diameter of the mouthwash gel 10 is relatively large. The height of the transition chamber 33 is insufficient to accommodate one mouthwash gel 10, and the transition chamber 33 cannot serve its purpose of temporarily storing one mouthwash gel 10. If h ≥ 2d, meaning the diameter d of the mouthwash gel 10 is greater than twice the height h of the transition chamber 33, then the height of the transition chamber 33 is relatively large, and the diameter of the mouthwash gel 10 is relatively small. The transition chamber 33 can accommodate two mouthwash gel 10s, but cannot achieve the purpose of separating multiple mouthwash gel 10s one by one. By d ≤ h < 2d, the diameter d of the mouthwash gel 10 is between the height h of the transition chamber 33 and twice the height h, allowing the height of the transition chamber 33 to accommodate at most one mouthwash gel 10, but not two. This allows it to accommodate one mouthwash gel 10 while simultaneously serving the purpose of separating multiple mouthwash gel 10s one by one. Specifically, h can be d, 1.1d, 1.2d, 1.3d, 1.4d, 1.5d, 1.55d, 1.6d...1.9d, etc.

[0076] If d > b, meaning the diameter d of the mouthwash gel 10 is greater than the minimum width b of the transition chamber 33, then the minimum width of the transition chamber 33 is relatively small, and the diameter of the mouthwash gel 10 is relatively large. The minimum width of the transition chamber 33 is insufficient to accommodate one mouthwash gel 10, and the transition chamber 33 cannot serve the purpose of temporarily storing one mouthwash gel 10. If b ≥ 2d, meaning the diameter d of the mouthwash gel 10 is greater than twice the minimum width b of the transition chamber 33, then the minimum width of the transition chamber 33 is relatively large, and the diameter of the mouthwash gel 10 is relatively small. The transition chamber 33 can accommodate two mouthwash gel 10, but cannot achieve the purpose of separating the mouthwash gel 10 one by one. With d ≤ b < 2d, the diameter d of the mouthwash gel 10 is between the minimum width b of the transition chamber 33 and twice the minimum width b of the transition chamber 33. This allows the minimum width of the transition chamber 33 to accommodate at most one mouthwash gel 10, but not two mouthwash gel 10. While accommodating one mouthwash gel 10, it also serves to separate multiple mouthwash gel 10s one by one. h can be b, 1.1b, 1.2b, 1.3b, 1.4b, 1.5b, 1.55b, 1.6b...1.9b, etc.

[0077] In one embodiment, such as Figures 4-7 As shown, both the first valve 31 and the second valve 32 include multiple claws 311. The multiple claws 311 of the first valve 31 are configured to move toward or away from each other, and the multiple claws 311 of the second valve 32 are configured to move toward or away from each other.

[0078] When the multiple claws 311 of the first valve 31 move closer to each other, the first valve 31 is closed, which serves to stop the mouthwash gel 10 in the storage chamber 1; when the multiple claws 311 of the first valve 31 move further away from each other, the first valve 31 is opened, which serves to output the mouthwash gel 10 in the storage chamber 1 to the transition chamber 33.

[0079] When the multiple claws 311 of the second valve 32 move closer to each other, the second valve 32 is closed, which serves to stop the mouthwash gel 10 in the transition chamber 33; when the multiple claws 311 of the second valve 32 move further away from each other, the second valve 32 is opened, which serves to output the mouthwash gel 10 in the transition chamber 33 to the delivery channel 4.

[0080] It is understood that each valve may have two locking claws 311, arranged opposite to each other, or at least three locking claws 311, arranged in a ring around the transition chamber 33. This embodiment does not limit the number of locking claws 311 on the valve; it can be adjusted according to actual production needs.

[0081] In one embodiment, such as Figures 4-7As shown, a sealing gasket 312 is provided on the side of the multiple claws 311 of the first valve 31 that are close to each other, for the isolation and sealing between the storage chamber 1 and the transition chamber 33; and / or, a sealing gasket 312 is provided on the side of the multiple claws 311 of the second valve 32 that are close to each other, for the isolation and sealing between the conveying channel 4 and the transition chamber 33.

[0082] Since the storage chamber 1 has only one delivery channel 4 connected to the water tank 2, it is isolated from the outside and has a sealed and waterproof function. By setting a sealing gasket 312 on the corresponding claw 311 of the valve, it is equivalent to sealing in the moving position. When the water flosser body is not shaken, the storage chamber 1 and the delivery channel 4 are sealed and isolated; only when the water flosser body is shaken will the storage chamber 1 and the delivery channel 4 be connected for a short time so that the mouthwash beads 10 can fall into the water tank 2 to form diluted mouthwash.

[0083] Specifically, such as Figure 4 As shown, in the initial unshaken state, multiple mouthwash beads 10 are located in the storage chamber 1; in the initial shaking state, only one mouthwash bead 10 is located on the first valve 31, at which time both the first valve 31 and the second valve 32 are closed; as Figure 5 As shown, the first valve 31 then opens, while the second valve 32 remains closed. The mouthwash gel 10 falls from the first valve 31 into the transition cavity between the first valve 31 and the second valve 32. Since the second valve 32 remains closed, the delivery channel 4 and the storage chamber 1 are sealed and isolated. Then, as... Figure 6 As shown, the first valve 31 is closed and the second valve 32 is open. The mouthwash beads 10 in the transition chamber 33 enter the conveying channel 4 through the second valve 32. Since the first valve 31 is closed, the conveying channel 4 and the storage chamber 1 are in a sealed and isolated state. Finally, as shown... Figure 7 As shown, after the mouthwash gel 10 has completely passed through the second valve 32, the second valve 32 is closed.

[0084] It is understandable that the second valve 32 can only be opened after the first valve 31 is closed. The first valve 31 can be controlled to automatically close 2 seconds after opening, and the second valve 32 will open after the first valve 31 is closed.

[0085] In one embodiment, a guide portion 313 is provided on one side of the plurality of claws 311 of the first valve 31 that are close to each other, and the guide portion 313 is used to guide a mouthwash bead 10; and / or,

[0086] The second valve 32 has a guide portion 313 on one side of the multiple claws 311 that are close to each other. The guide portion 313 is used to guide a mouthwash gel bead 10.

[0087] Since the storage chamber 1 can hold multiple mouthwash beads 10, opening the first valve 31 or the second valve 32 may result in more than one mouthwash bead 10 falling. A guide section 313 is provided on the side of the first valve 31 facing the storage chamber 1. The guide section 313 guides only one mouthwash bead 10 at a time, thus limiting the flow and preventing multiple mouthwash beads 10 from falling from the storage chamber 1 through the first valve 31. Similarly, a guide section 313 is provided on the side of the second valve 32 facing the storage chamber 1. This guide section 313 also guides only one mouthwash bead 10 at a time, thus limiting the flow and preventing multiple mouthwash beads 10 from falling through the second valve 32 into the delivery channel 4.

[0088] It is understandable that the guide part 313 can be provided only in the first valve 31, or only in the second valve 32, or both the first valve 31 and the second valve 32 can have the guide part 313. Since the first valve 31 is located upstream of the second valve 32, if the first valve 31 has the guide part 313, it can already limit the fall of only one mouthwash gel bead 10. In this case, the second valve 32 may not have the guide part 313. However, the presence of the guide part 313 in both valves provides a double safety measure, ensuring the accuracy of limiting the passage of only one mouthwash gel bead 10.

[0089] In one embodiment, the guide portion 313 is a receiving groove with its opening facing the storage chamber 1, and the receiving groove is used to receive at least a portion of a mouthwash gel 10.

[0090] The opening of the receiving slot is set towards the storage chamber 1, so that the mouthwash gel 10 located in the storage chamber 1 can enter the receiving slot through the opening of the receiving slot. The receiving slot is used to accommodate at least a portion of a mouthwash gel 10, that is, the internal space of the receiving slot is relatively small, and the receiving slot can only accommodate a maximum of one mouthwash gel 10, so as to avoid multiple mouthwash gels 10 falling at the same time.

[0091] It is understandable that the receiving groove can be a V-shaped groove, a C-shaped groove, or a U-shaped groove, etc.

[0092] In one embodiment, the mouthwash generating structure further includes an acceleration sensor (not shown) electrically connected to the switch assembly 3. The acceleration sensor is configured to detect the acceleration signal of the shaking to control the opening and closing of the switch assembly 3.

[0093] When the user shakes the water flosser vigorously, the acceleration sensor receives a signal and transmits it to the controller, which then activates the control switch 3. The mouthwash beads 10 automatically fall into the water tank 2 and dissolve upon contact with water. Therefore, mouthwash is created simply by shaking the device; it's easy to operate and quite fun.

[0094] Understandably, the actual swaying amplitude and speed along the first direction need to be adjusted according to the actual product to achieve the best user experience.

[0095] In one embodiment, the sensor is a triaxial accelerometer sensor used to identify swaying acceleration along a first direction; wherein the first direction is different from the direction of the punch movement.

[0096] like Figures 8-9 As shown, existing water flossers move slowly left and right in the second direction during use, but to activate the switch assembly 3, it is necessary to shake it up and down significantly in the first direction. An accelerometer can be used for this purpose, and the shaking acceleration and direction can be programmed. In particular, a triaxial accelerometer sensor can be programmed to recognize shaking in the first direction. Since there is no significant up-and-down shaking in the first direction during actual use of the water flosser, accidental activation can be effectively avoided.

[0097] Understandably, the triaxial accelerometer sensor is specifically a high-sensitivity vibration sensor to ensure sensitivity and accuracy in detecting swaying along the first direction.

[0098] like Figures 10-13 As shown, this embodiment also provides a water flosser, including the mouthwash generating structure described above.

[0099] The water flosser provided in this embodiment has a storage chamber 1 that provides space for mouthwash beads 10, and a water tank 2 that provides space for cleaning water while also providing space for the mouthwash beads 10 to dissolve and mix with the cleaning water. By setting one end of the delivery channel 4 to be selectively connected to the storage chamber 1 and the other end to the water tank 2, the delivery channel 4 serves to deliver the mouthwash beads 10 in the storage chamber 1 to the water tank 2. After the user places the mouthwash beads 10 into the storage chamber 1, if they want to use diluted mouthwash to freshen their breath during the water flossing process, the switch component 3 is configured to be turned on when shaken. Simply shake the water flosser body a few times to turn on the switch component 3, connecting the storage chamber 1 and the delivery channel 4. The mouthwash beads 10 in the storage chamber 1 will then automatically fall into the delivery channel 4 and fall into the water tank 2 under the conveying action of the delivery channel 4. The mouthwash beads 10 dissolve upon contact with water, thus obtaining diluted mouthwash to achieve the purpose of freshening breath. The process of producing mouthwash is time-saving, labor-saving, easy to operate, and quite fun.

[0100] In one embodiment, such asFigures 13-14 As shown, the oral irrigator also includes a nozzle 100 and a delivery assembly 200, one end of which is connected to the water tank 2 and the other end of which is connected to the nozzle 100.

[0101] In normal rinsing mode, without shaking the water flosser, the water in tank 2 is delivered to nozzle 100 via delivery assembly 200, which rinses the teeth. In mouthwash mode, shaking the water flosser causes the mouthwash beads 10 to fall into tank 2, dissolve in water, and become mouthwash. This mouthwash is then delivered to nozzle 100 via delivery assembly 200, which rinses the teeth. Different modes are available to meet different user needs.

[0102] In one embodiment, such as Figures 13-14 As shown, the oral irrigator also includes a main body 800 and a motor 300, a first gear 400, a second gear 500, a cam 600, and a piston pump 700, all housed within the main body 800. The output end of the motor 300 is connected to the first gear 400, which meshes with the second gear 500. The second gear 500 and the cam 600 are coaxially arranged to form an eccentric wheel structure, which drives the piston to reciprocate, thereby drawing out the cleaning water or mouthwash from the water tank 2, which enters the piston pump 700, and is then sprayed out from the nozzle 100, thus realizing the pulse water function of the oral irrigator.

[0103] Understandably, the main body 800 is equipped with a power switch 801 and a gear selector 802. The power switch 801 and gear selector 802 are electrically connected to the motherboard. Press and hold the power switch 801 to turn the machine on and off, and press the power switch 801 briefly to pause or start the machine. The gear selector 802 is used to switch between different gears to change the speed and volume of water output from the nozzle 100.

[0104] It is understandable that a partition is provided inside the main body 800, which divides the inner cavity of the main body 800 into two parts. One part is used to accommodate the motor 300, the first gear 400, the second gear 500, the cam 600, and the piston pump 700, while the other end serves as the storage chamber 1 and the conveying channel 4.

[0105] The working process of the water flosser provided in this embodiment is as follows:

[0106] When the water flosser is turned off, shaking the water flosser will disable the high-sensitivity vibration sensor.

[0107] Press and hold the power button to turn on the water flosser. The high-sensitivity vibration sensor will then activate. When the user shakes the water flosser at a specific frequency, such as shaking it up and down in the first direction at least twice within one second or shaking the water flosser body continuously for two seconds, the high-sensitivity vibration sensor switch on the main board will receive the vibration signal and control the switch assembly 3 to open. That is, the first valve 31 will automatically close after opening for two seconds. After the first valve 31 closes, the second valve 32 will open, causing the mouthwash beads 10 to automatically fall into the water tank 2, where they will dissolve in water to form mouthwash, thus realizing the mouthwash function of the water flosser.

[0108] Press and hold the power button to turn on the water flosser. If the user does not shake the device in the first direction, the cleaning water in the water tank 2 will be drawn out and enter the piston pump 700, and then sprayed out from the nozzle 100 to realize the water flosser's cleaning water function.
