[0010] In some embodiments, the adjustment column includes a first column and a second column, the second column is arranged on a side of the first column away from the bottom of the second groove, and the cross-sectional area of the second column gradually decreases from an end close to the first column to an end away from the first column; When in the first adjustment position, the outer wall of the first column and the inner wall of the first sealing ring abut against each other to form a sealed connection structure; In the second adjustment position, the outer wall of the first column and the inner wall of the first sealing ring are spaced apart to form the second air inlet end.

The liquid flowing through the liquid inlet end is a negative pressure liquid due to the negative pressure suction of the pump body. According to the "Bernoulli principle", the pressure is low where the flow rate is high. When the low-pressure liquid passes through the regulating valve, a "Venturi effect" is formed, so that the liquid flowing through the regulating valve causes the external air pressure of the regulating valve to be lower than the pressure at the liquid inlet end, so that the low-pressure gas will flow into the liquid inlet end, and then mix at the liquid inlet end to form a liquid with bubbles.
[0017] By movably setting the regulating valve on one side of the main body and adjusting the regulating valve from the first adjustment position to the second adjustment position, the guide area of the second air inlet end gradually increases, that is, the flow rate of the gas flowing through the second air inlet end gradually increases, thereby gradually increasing the flow rate of the gas entering the outlet end, so that the diameter of the microbubbles generated after the gas mixes with the liquid at the outlet end gradually increases, thereby realizing dynamic adjustment of the diameter size of the microbubbles in the water flow ejected from the nozzle. When the diameter of the bubbles in the liquid is small, the liquid ejected from the nozzle can form a strong pulse water flow, which is suitable for removing stubborn residues; when the diameter of the bubbles in the liquid is larger, the water flow ejected from the nozzle is softer, which can reduce the risk of bleeding gums of users and is suitable for users with sensitive oral cavity.

[0028] like Figures 1 to 5 As shown, some embodiments of the present application provide a water flosser having a first direction Z, which is mainly used for oral cleaning. The air intake of the water flosser is dynamically adjusted to adjust the ratio of the liquid and gas mixture, thereby controlling the size of bubbles generated after the gas and liquid are mixed, so as to improve the cleaning efficiency of the oral cavity, thereby meeting the different oral cleaning needs of users.
[0029] The oral irrigator includes a body 100 , a nozzle 200 , a connecting head 300 , a pump body 900 and a regulating valve 400 .
[0030] It should be noted that an installation space is defined inside the body 100 , and the connector 300 is disposed in the installation space and fixedly connected to the body 100 to ensure the stability of the connector 300 in the installation space.
[0031] The nozzle 200 is disposed at one end of the body 100 along the first direction Z. The connection between the nozzle 200 and the body 100 includes any one of threaded connection, snap connection, adhesive connection, magnetic connection, interference fit, and bolt connection, which can be specifically set according to actual conditions. It is understood that by making the nozzle 200 and the body 100 detachable, the nozzle 200 can be easily cleaned or replaced to meet the user's oral hygiene needs.
[0032] In this embodiment, the connector 300 is disposed within the body 100. The connector 300 has a first air inlet end 310, a liquid inlet end 320, and an outlet end 330, which are interconnected in pairs. The outlet end 330 is connected to the nozzle 200, so that external gas can enter the outlet end 330 through the first air inlet end 310, and external liquid can enter the outlet end 330 through the liquid inlet end 320. As a result, the gas flowing through the first air inlet end 310 and the liquid flowing through the liquid inlet end 320 can mix at the outlet end 330 to form microbubbles in the liquid. It is understood that the mixed liquid enters the nozzle 200 through the outlet end 330 and is sprayed out from the nozzle head of the nozzle 200.
[0033] It should be noted that, in this embodiment, the pump body 900 is arranged in the main body 100, one end of the pump body 900 is connected to the outlet end 330 through the liquid inlet pipe 1000, and the other end of the pump body 900 is connected to the nozzle 200, so that when the pump body 900 is in operation, the liquid flowing through the nozzle 200 is subjected to the pressure of the pump body 900 to form a positive pressure liquid at the outlet of the nozzle 200. The liquid flowing through the liquid inlet end 320 is a negative pressure liquid due to the negative pressure suction of the pump body 900. According to the "Bernoulli principle", it can be seen that the pressure is small where the flow rate is large. When the low-pressure liquid passes through the regulating valve 400, a "Venturi effect" is formed, so that the liquid flowing through the regulating valve 400 will cause the external air pressure of the regulating valve 400 to be lower than the pressure at the liquid inlet end 320, so that the low-pressure gas will flow into the liquid inlet end 320, and then mix at the liquid inlet end 320 to form a liquid with bubbles. The high-pressure gas-liquid mixed medium formed during the operation of the pump body 900 is ejected through the nozzle 200.
[0034] Specifically, the pump body 900 has a positive pressure liquid outlet end and a negative pressure liquid inlet end. The positive pressure liquid outlet end of the pump body 900 is connected to the nozzle 200, and the negative pressure liquid inlet end of the pump body 900 is connected to the outlet end 330 of the connecting head 300 through the liquid inlet pipe 1000. That is, the regulating valve 400 is connected to the negative pressure liquid inlet end of the pump body 900.
[0035] It should be noted that the Venturi effect is a fluid mechanics phenomenon, which refers to the phenomenon that the flow velocity increases and the pressure decreases when a confined fluid flows through a narrow cross-section.
[0036] In addition, the regulating valve 400 is movably arranged on one side of the main body 100, and the regulating valve 400 defines an air flow channel 410, and the air flow channel 410 has a second air inlet end 411 and an air outlet end 412, and the air outlet end 412 is connected to the first air inlet end 310, and the second air inlet end 411 is used to connect with external gas, so that external gas can enter the air flow channel 410 through the second air inlet end 411, and enter the outlet end 330 through the air outlet end 412 and the first air inlet end 310, and then be discharged from the outlet end 330 through the nozzle 200.
[0037] In this embodiment, the regulating valve 400 has a first regulating position and a second regulating position, and the regulating valve 400 can switch between the first regulating position and the second regulating position, thereby regulating the flow of gas entering the air flow channel 410 through the second air inlet end 411, thereby controlling the flow of gas entering the outlet end 330.
[0038] It should be noted that when the regulating valve 400 is in the first regulating position, the second air inlet end 411 is sealed and closed, i.e., external gas cannot enter the air flow channel 410 through the second air inlet end 411. In other words, in this state, only liquid can enter the outlet end 330 through the liquid inlet end 320, i.e., there are no microbubbles in the liquid sprayed from the nozzle 200.
[0039] When the regulating valve 400 is in the second regulating position, the second air inlet end 411 is opened, that is, the second air inlet end 411 is connected to the air outlet end 412, and allows external gas to enter the air outlet end 412 through the second air inlet end 411, so that the gas flowing through the air flow channel 410 can mix with the liquid flowing through the liquid inlet end 320 at the outlet end 330, thereby generating microbubbles in the liquid flowing through the nozzle 200.
[0040] It should be noted that, in the process of adjusting the regulating valve 400 from the first adjustment position to the second adjustment position, the guide area of the second air inlet end 411 gradually increases, that is, the flow rate of the gas flowing through the second air inlet end 411 gradually increases, thereby causing the flow rate of the gas entering the outlet end 330 to gradually increase, so that the diameter of the microbubbles generated after the gas is mixed with the liquid at the outlet end 330 gradually increases, thereby realizing dynamic adjustment of the diameter of the microbubbles in the water flow ejected from the nozzle 200.
[0041] Furthermore, when the diameter of the bubbles in the liquid is small, the liquid sprayed from the nozzle 200 can form a strong pulse water flow, which is suitable for removing stubborn residues; when the diameter of the bubbles in the liquid is large, the water flow sprayed from the nozzle 200 is softer, which can reduce the risk of bleeding gums of the user and is suitable for users with sensitive oral cavity.
[0042] In this embodiment, by controlling the diameter of the bubbles in the liquid, the impact of the high-pressure water flow on the user's oral cavity is buffered by gas, thereby effectively reducing the probability of gingival bleeding, making it suitable for people with oral sensitivity. In addition, it is worth noting that when the microbubbles are impacted by the water flow, they burst and produce a cavitation effect, which enhances the water flow's penetration and improves the efficiency of stripping dental plaque and food debris. It can penetrate into the area below 3mm in the gingival sulcus, and the dental plaque removal rate is increased by 40%, thereby further improving the quality of oral cleaning for the user. By adjusting the flow of gas flowing through the outlet port 330, the amount of pure water used can be effectively reduced, reducing the cost of oral cleaning.
[0043] It should be noted that the cavitation effect refers to the tiny shock waves generated when bubbles burst in high-speed water flow. This instantaneous release of energy can destroy the adhesion structure of bacterial biofilms, especially stubborn deposits near the gum line and in the gaps between teeth. The microjets generated by the bubble burst can penetrate into narrow areas that are difficult for ordinary water flow to reach (such as gaps between teeth and pits and fissures).
[0044] Secondly, by adjusting the diameter of the microbubbles in the liquid, the contact area between the liquid and the tooth surface can be increased, thereby improving the cleaning efficiency.
[0045] like Figures 3 to 5 As shown, in some embodiments of the present application, the oral irrigator has a second direction X perpendicular to the first direction Z, and the regulating valve 400 includes a valve core 420 and an adjusting knob 430.
[0046] The valve core 420 is connected to the body 100 by any one of threaded connection, snap connection, bonding, magnetic connection, interference fit or riveting, which can be set according to actual conditions.
[0047] In addition, the adjusting knob 430 is movably connected to the valve core 420 along the second direction X, that is, the adjusting knob 430 can move relative to the valve core 420 along the second direction X. It is understandable that the connection between the adjusting knob 430 and the valve core 420 includes a threaded connection or a sliding connection.
[0048] By controlling the positions of the regulating knob 430 and the valve core 420 along the second direction X, the flow rate of the gas flowing through the second gas inlet end 411 is adjusted, thereby controlling the flow rate of the gas entering the outlet end 330 .
[0049] In this embodiment, the valve core 420 defines the air flow channel 410, and one end of the valve core 420 is connected to the first air inlet end 310. Specifically, the end of the valve core 420 away from the adjusting knob 430 along the second direction X is inserted into the first air inlet end 310, thereby connecting the air flow channel 410 with the first air inlet end 310. The adjusting knob 430 is movably connected to the end of the valve core 420 away from the first air inlet end 310, so that the adjusting knob 430 can move relative to the valve core 420 along the second direction X, thereby adjusting the caliber of the second air inlet end 411 during the movement of the adjusting knob 430 relative to the valve core 420 along the second direction X, thereby adjusting the flow rate of gas flowing through the air flow channel 410 through the second air inlet end 411.
[0050] When the adjusting knob 430 is in the first adjusting position relative to the valve core 420, the adjusting knob 430 is partially set in the second air inlet end 411, and the second air inlet end 411 is sealed by the adjusting knob 430 set at the second air inlet end 411, thereby sealing the air flow channel 410 to prevent external gas from entering the outlet end 330 through the second air inlet end 411.
[0051] When the adjusting knob 430 is in the second adjusting position relative to the valve core 420, the adjusting knob 430 is spaced apart from the second air inlet end 411, so that external gas can enter the air flow channel 410 through the second air inlet end 411 and can mix with the liquid flowing into the outlet end 330, thereby generating microbubbles in the liquid.
[0052] It can be understood that, by gradually moving the adjusting knob 430 from the first adjusting position to the second adjusting position relative to the valve core 420, the guide area of the second air inlet end 411 gradually increases, that is, the gas flow rate flowing into the air flow channel 410 through the second air inlet end 411 gradually increases, thereby adjusting the ratio of gas and liquid entering the outlet end 330, thereby controlling the diameter of the microbubbles mixed in the liquid.
[0053] like Figure 8 and Figure 9 As shown, in some embodiments of the present application, the valve core 420 includes a connecting end 421 and a connecting pipe 422 connected to each other, and the connection method between the connecting pipe 422 and the connecting end 421 includes any one of threaded connection, clamping, bonding or integral molding.
[0054] In this embodiment, the connecting end 421 and the connecting pipe 422 are integrally formed to form the valve core 420 , so as to improve the overall strength and stability of the valve core 420 .
[0055] A guide groove 423 is provided on the side of the connecting end 421 facing away from the connecting tube 422 along the second direction X. The notch of the guide groove 423 is arranged along the second direction X away from the connecting tube 422. The guide groove 423 has a first groove bottom 424 on one side along the second direction X. The first groove bottom 424 is provided with a through hole 425. The guide groove 423 is connected to the air flow channel 410 through the through hole 425, that is, external gas can enter the outlet end 330 through the guide groove 423, the through hole 425, and the connecting tube 422. It should be noted that the air flow channel 410 described in any of the above embodiments is formed by sequentially connecting the guide groove 423, the through hole 425, and the connecting tube 422.
[0056] In this embodiment, the axis of the guide groove 423, the axis of the through hole 425 and the axis of the connecting pipe 422 coincide with each other, and the inner diameter of the guide groove 423 is larger than the inner diameter of the through hole 425, the inner diameter of the through hole 425 is larger than the inner diameter of the connecting pipe 422, and the inner diameter of the connecting pipe 422 is larger than or equal to the inner diameter of the first air inlet end 310 to ensure the flow rate of the gas entering the first air inlet end 310.
[0057] In this embodiment, the connecting tube 422 passes through the main body 100 along the second direction X and is arranged inside the main body 100. The side of the connecting end 421 facing the connecting tube 422 abuts against the outer wall of the main body 100, so as to limit the connecting end 421 through the outer wall of the main body 100 to ensure the accuracy of the connection position of the valve core 420 and the main body 100.
[0058] like Figure 5 and Figure 8 As shown, in some embodiments of the present application, a plurality of spaced-apart connecting members 426 are provided on the side of the connecting end 421 facing the connecting tube 422, and the end of the connecting member 426 facing away from the connecting end 421 is inserted into the main body 100 and snapped together with the inner wall of the main body 100 to form a snap connection.
[0059] The number of the connecting members 426 can be two or more than two, and can be set according to actual conditions.
[0060] It should be noted that there is a gap between the connecting piece 426 and the connecting pipe 422 .
[0061] In some embodiments, there are two connecting members 426, which are respectively located on two opposite sides of the connecting pipe 422 perpendicular to the second direction X. The two connecting members 426 are respectively connected to the inner wall of the main body 100, which not only ensures the stability of the connection between the valve core 420 and the main body 100, but also reduces the production cost of the valve core 420 by controlling the number of connecting members 426.
[0062] It can be understood that by placing the connecting end 421 against the outer wall of the main body 100 on one side of the main body 100 and connecting it to the inner wall of the main body 100 through the connecting member 426, the valve core 420 is fixedly connected to the main body 100 to improve the stability of the valve core 420 on the main body 100.
[0063] like Figure 5 As shown, in some embodiments of the present application, the valve core 420 includes a first sealing ring 500 , and the first sealing ring 500 is disposed in the guide groove 423 .
[0064] Along a direction perpendicular to the second direction X, the outer wall of the first sealing ring 500 abuts against the inner wall of the guide groove 423. Furthermore, one side of the first sealing ring 500 along the second direction X abuts against the first groove bottom 424. This means that the inner wall of the guide groove 423 and the first groove bottom 424 limit the first sealing ring 500, thereby improving the stability of the first sealing ring 500 within the guide groove 423.
[0065] The inner diameter of the first sealing ring 500 is greater than or equal to the aperture of the through hole 425 to prevent the first sealing ring 500 from affecting the air flow through the air flow channel 410 , thereby ensuring the stability of the air flow through the air flow channel 410 .
[0066] In addition, the first sealing ring 500 is at least one of a rubber sealing ring and a silicone sealing ring.
[0067] It should be noted that when the adjusting knob 430 is in the first adjustment position relative to the valve core 420, a portion of the adjusting knob 430 abuts against the inner wall of the first sealing ring 500, thereby sealing the second air inlet end 411 through the first sealing ring 500 and the adjusting knob 430. When the adjusting knob 430 is in the second adjustment position relative to the valve core 420, the adjusting knob 430 is spaced apart from the inner wall of the first sealing ring 500, thereby opening the second air inlet end 411, allowing external gas to enter the air flow channel 410 through the second air inlet end 411.
[0068] By disposing an elastic first sealing ring 500 in the guide groove 423 , the sealing quality of the regulating knob 430 to the second air inlet end 411 is improved when the regulating knob 430 is in the first regulating position relative to the valve core 420 .
[0069] like Figures 5 to 7As shown, in some embodiments of the present application, the adjusting knob 430 is provided with a mounting groove 431, and the mounting groove 431 has a second groove bottom 432 on one side along the second direction X, and the second groove bottom 432 is provided with an adjusting column 433 extending along the second direction X, and the side wall of the adjusting column 433 and the inner wall of the second groove bottom 432 are combined to form an annular channel 434, and the axis of the annular channel 434 coincides with the axis of the guide groove 423.
[0070] In this embodiment, the adjusting knob 430 is movably connected to the connecting end 421 along the second direction X.
[0071] In which, the end of the connecting end 421 facing away from the connecting pipe 422 is accommodated in the annular channel 434, and the adjusting column 433 is at least partially penetrated into the guide groove 423, so as to define the second air inlet end 411 described in any of the above embodiments through the outer wall of the adjusting column 433, the inner wall of the guide groove 423 and the inner wall of the first sealing ring 500.
[0072] It can be understood that when the adjusting knob 430 moves along the second direction X relative to the connecting end 421 , the adjusting post 433 moves along the second direction X relative to the first sealing ring 500 .
[0073] Specifically, when the adjusting knob 430 is in the first adjustment position relative to the valve core 420, the side wall of the adjusting post 433 abuts against the inner wall of the first sealing ring 500, thereby sealing the second air inlet end 411 through the first sealing ring 500 and the adjusting post 433. When the adjusting knob 430 is in the second adjustment position relative to the valve core 420, the side wall of the adjusting post 433 is spaced apart from the inner wall of the first sealing ring 500, thereby opening the second air inlet end 411, allowing external gas to enter the air flow channel 410 through the second air inlet end 411.
[0074] It can be understood that by controlling the position of the adjusting knob 430 relative to the valve core 420 to adjust the distance between the inner wall of the first sealing ring 500 and the outer wall of the adjusting column 433, the amount of air flowing through the second air inlet end 411 is adjusted, thereby adjusting the amount of air entering the outlet end 330.
[0075] like Figures 5 to 7 As shown, in some embodiments of the present application, the adjustment column 433 includes a first column 4331 and a second column 4332. The first column 4331 and the second column 4332 are coaxially connected, and the connection method includes any one of threaded connection, clamping, bonding, or integral molding. In this embodiment, the first column 4331 and the second column 4332 are integrally molded to ensure the strength and stability of the adjustment column 433.
[0076] Among them, the second column 4332 is arranged on the side of the first column 4331 away from the second groove bottom 432, and the cross-sectional area of the second column 4332 gradually decreases from the end close to the first column 4331 to the end away from the first column 4331, that is, the second column 4332 is a conical structure.
[0077] When the adjusting knob 430 is at the first adjusting position relative to the valve core 420 , the outer wall of the first column 4331 and the inner wall of the first sealing ring 500 abut against each other to form a sealing connection structure, thereby sealing the second air inlet end 411 .
[0078] When the adjusting knob 430 is in the second adjusting position relative to the valve core 420, the outer wall of the first column 4331 is spaced apart from the inner wall of the first sealing ring 500, thereby opening the second air inlet end 411 so that the external gas can be guided into the air flow channel 410 through the gap between the first column 4331 and the first sealing ring 500.
[0079] It can be understood that when the adjustment knob 430 moves from the first adjustment position to the second adjustment position relative to the valve core 420, the annular flow area between the side wall of the second cylinder 4332 and the inner wall of the first sealing ring 500 gradually increases to control the flow rate and flow of the gas flowing through the air flow channel 410, thereby controlling the flow of gas entering the outlet end 330, and thus controlling the diameter of the microbubbles generated after mixing with the liquid at the outlet end 330.
[0080] like Figure 5 and Figure 7 As shown, in some embodiments of the present application, the outer diameter of the end of the second cylinder 4332 close to the first cylinder 4331 is greater than the inner diameter of the first sealing ring 500, and the outer diameter of the end of the second cylinder 4332 away from the first cylinder 4331 is smaller than the inner diameter of the through hole 425, so as to ensure that the second cylinder 4332 can pass through the first sealing ring 500, so that when the adjusting knob 430 moves relative to the valve core 420 along the second direction X, the side wall of the second cylinder 4332 can abut against the inner wall of the first sealing ring 500 to form a sealing structure, and the side wall of the second cylinder 4332 can be separated from the inner wall of the first sealing ring 500 and open the second air inlet end 411.
[0081] like Figure 5 and Figure 8 As shown, in some embodiments of the present application, a first connecting portion 427 is provided on the outer peripheral side of the connecting end 421, and a second connecting portion 435 is provided on the inner wall of the mounting groove 431, and the first connecting portion 427 and the second connecting portion 435 are movably connected along the second direction X.
[0082] For example, in this embodiment, the first connecting portion 427 is an external thread, and the second connecting portion 435 is an internal thread. The internal thread is connected to the external thread, thereby threading the adjusting knob 430 and the connecting end 421. By rotating the adjusting knob 430, the relative position of the adjusting knob 430 and the valve core 420 along the second direction X is controlled, thereby adjusting the amount of air flowing through the air flow channel 410.
[0083] Optionally, in some embodiments, the first connecting portion 427 is a pulley, the second connecting portion 435 is a slide rail, and the pulley and the slide rail are slidably connected along the second direction X, so that the amount of air flowing through the air flow channel 410 can be adjusted by sliding the adjusting knob 430 relative to the valve core 420 along the second direction X.
[0084] like Figure 2 、 Figure 7 and Figure 8 As shown, in some embodiments of the present application, the adjusting knob 430 is provided with a plurality of spaced-apart guide holes 436 on a side away from the valve core 420 along the second direction X, and the guide holes 436 penetrate the second groove bottom 432 along the second direction X. The guide holes 436 are connected to the guide groove 423 through the annular channel 434, so that external gas can enter the guide groove 423 through the guide holes 436.
[0085] The number of the guide holes 436 can be two or more than two, and can be set according to actual conditions.
[0086] It should be noted that the guide holes 436 are spaced apart from the adjustment column 433 . In some embodiments, a plurality of guide holes 436 are arranged in a circular pattern at equal intervals along the axis of the adjustment column 433 .
[0087] In this embodiment, there are two guide holes 436 , and the two guide holes 436 are located at two opposite sides of the axis of the adjustment column 433 along a direction perpendicular to the second direction X.
[0088] like Figure 5 As shown, in some embodiments of the present application, the water flosser further includes a filter element 600, which is sleeved on the first column 4331, and the inner wall of the filter element 600 abuts against the outer wall of the first column 4331, and the filter element 600 abuts against the inner wall of the mounting groove 431 along a side perpendicular to the second direction X.
[0089] Along the second direction X, one side of the filter element 600 abuts against the second groove bottom 432, and the other side of the filter element 600 abuts against the side of the connecting end 421 away from the connecting pipe 422, so as to provide a limiting effect on the filter element 600 through the second groove bottom 432 and the connecting end 421, so as to ensure the stability of the filter element 600 in the installation groove 431, and at the same time provide a filtering effect on the gas flowing through the guide hole 436 through the filter element 600.
[0090] like Figure 5 As shown, in some embodiments of the present application, a sealing tube 700 is provided inside the first air inlet end 310, the side wall of the sealing tube 700 is connected to the inner wall of the first air inlet end 310, and the inner wall of the sealing tube 700 is connected to the outer wall of the connecting tube 422 to improve the sealing quality between the connecting tube 422 and the first air inlet end 310.
[0091] like Figure 2 and Figure 5 As shown, in some embodiments of the present application, a mounting hole 110 is provided on the side wall of the main body 100, the connecting pipe 422 is passed through the mounting hole 110, and an annular groove 4221 is provided on the outer wall of the connecting pipe 422. The groove wall of the annular groove 4221 and the hole wall of the mounting hole 110 are combined to form an annular hole, and a sealing ring 800 is provided in the annular hole. The sealing ring 800 abuts against the groove wall of the annular groove 4221 and the hole wall of the mounting hole 110 to improve the sealing quality between the connecting pipe 422 and the main body 100, thereby improving the sealing quality of the connection between the valve core 420 and the main body 100.
