[0052] Traditional water flossers mostly use a liquid pump to drive water to spray out from a nozzle to rinse the teeth, thereby cleaning the dental plaque on the tooth surface and the food residues in the gaps between the teeth through the impact force of the water. However, this method has limited cleaning effects. For example, it cannot kill bacteria in the mouth, and cannot reduce or eliminate bad breath. In order to improve the cleaning effect of water flossers, some water flossers are equipped with a functional liquid tank, which contains functional liquids with specific effects (such as sterilization, fresh breath, etc.).

[0053] Since the functional liquid is a consumable, the functional liquid tank needs to be replaced when the functional liquid is used up. Therefore, for a water flosser equipped with a functional liquid tank, how to quickly and conveniently replace the functional liquid tank is a problem that needs to be considered. Based on this, an embodiment of the present application provides a water flosser that can more conveniently replace the functional liquid tank.

[0054] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5As shown, the oral irrigator 1 provided in the embodiment of the present application includes a housing 10, a functional liquid tank 20, a water tank 60, a nozzle 50, a first liquid pump 30 and a flow channel assembly 40. Specifically, an open mounting groove 101 is formed on the top of the housing 10, the opening of the mounting groove 101 faces upward, and a mounting cavity 102 is provided inside the housing 10. The functional liquid tank 20 is installed in the mounting groove 101, and the functional liquid tank 20 is used to contain functional liquid, the water tank 60 is connected to the housing 10, and the water tank 60 is used to store water, and the nozzle 50 is connected to the housing 10. The first liquid pump 30 has a liquid inlet and a liquid outlet. The flow channel assembly 40 and the first liquid pump 30 are both located in the installation cavity 102. The flow channel assembly 40 defines a first flow path 401, a second flow path 402 and a third flow path 403. The water tank 60 is connected to the liquid inlet through the first flow path 401, and the liquid outlet is connected to the nozzle 50 through the second flow path 402. One end of the third flow path 403 is connected to the functional liquid tank 20, and the other end of the third flow path 403 is connected to one of the first flow path 401 and the second flow path 402.

[0055] The functional liquid tank 20 is used to contain the functional liquid and provide the functional liquid to the water flosser 1 so that the water flosser 1 can spray the functional liquid. For example, the functional liquid can be a preparation with functions such as sterilization, breath freshening, and inflammation treatment. The water tank 60 is used to supply water to the water flosser 1. The first liquid pump 30 provides the main power for the liquid flow in the water flosser 1. Under the action of the first liquid pump 30, water, functional liquid, or a mixture of the two can be sprayed out through the nozzle 50.

[0056] Specifically, the water tank 60 of the oral irrigator 1 is connected to the liquid inlet of the first liquid pump 30 through the first flow path 401, the liquid outlet of the first liquid pump 30 is connected to the nozzle 50 of the oral irrigator 1, and the functional liquid tank 20 is connected to one of the first flow path 401 and the second flow path 402 through the third flow path 403. In this way, under the action of the first liquid pump 30, the functional liquid in the functional liquid tank 20 can enter the first flow path 401 or the second flow path 402 through the third flow path 403, and finally spray out through the nozzle 50. The oral irrigator 1 in the embodiment of the present application can not only spray water, but also spray functional liquids with functions such as sterilization, fresh breath, and treatment of inflammation, so that the cleaning effect on the oral cavity can be improved.

[0057] The oral irrigator 1 in the embodiment of the present application has an open installation groove 101 formed on the top of the shell 10, and the functional liquid tank 20 can be installed in the installation groove 101, so that the functional liquid tank 20 is located at the top position of the oral irrigator 1. Such a configuration makes the replacement process of the functional liquid tank 20 extremely convenient, and the operation of installing or removing the functional liquid tank 20 can be completed by inserting it downward or pulling it upward, thereby, the functional liquid tank 20 can be replaced quickly and conveniently.

[0058] In addition, setting the functional liquid tank 20 at the top position of the oral irrigator 1 can also facilitate the user to observe the functional liquid tank 20, so that the user can timely grasp the remaining amount of functional liquid in the functional liquid tank 20, so that the user can prepare a new functional liquid tank 20 in advance.

[0059] Furthermore, a mounting groove 101 is formed on the top of the shell 10, and a mounting cavity 102 is formed inside the shell 10. The first liquid pump 30, the flow channel assembly 40, etc. are all located in the mounting cavity 102, which separates the functional liquid tank 20 and the first liquid pump 30, the flow channel assembly 40 and other structures from each other, thereby avoiding interference between the functional liquid tank 20 and other devices.

[0060] In some embodiments, Figure 3 , Figure 6 , Figure 7 , Figure 8 as well as Fig. 9 As shown, the interior of the functional liquid tank 20 defines a receiving chamber 201 for receiving the functional liquid, the bottom of the functional liquid tank 20 is provided with a flow channel portion 202 extending downward, the interior of the flow channel portion 202 is provided with a liquid channel 2021 communicating with the receiving chamber 201, and a packaging member 203 is provided in the liquid channel 2021, the packaging member 203 seals the liquid channel 2021, and the packaging member 203 includes a pierceable film 2031. The flow channel assembly 40 includes a piercing component 404, and a flow channel 405 is formed inside the piercing component 404. When the functional liquid tank 20 is installed in the installation groove 101, the piercing component 404 can pierce the pierceable film 2031 to make the flow channel 405 communicate with the liquid channel 2021, and the flow channel 405 constitutes a part of the third flow path 403.

[0061] It can be understood that the inner diameter of the liquid channel 2021 is smaller than the inner diameter of the accommodating chamber 201, so that it is more conducive to controlling the output speed of the functional liquid.

[0062] The package 203 can seal the liquid channel 2021, which makes the functional liquid tank 20 have a good sealing effect when it is not installed and used, thereby ensuring that the functional liquid in the accommodating cavity 201 will not be contaminated or volatilized. The package 203 includes a puncturable film 2031, which can be punctured relatively easily. When the puncturable film 2031 is punctured, the package 203 loses its sealing effect, and the liquid channel 2021 is unblocked. When the functional liquid tank 20 is installed in the mounting groove 101 of the housing 10, the puncturing component 404 in the flow channel assembly 40 can puncture the puncturable film 2031, so that the liquid channel 2021 is connected to the third flow path 403 of the flow channel assembly 40. At this time, the functional liquid tank 20 can supply functional liquid to the water flosser 1.

[0063] In addition, a flow channel portion 202 extending downward is provided at the bottom of the functional liquid tank 20, and the functional liquid in the functional liquid tank 20 can flow out through the liquid channel 2021 of the flow channel portion 202. The liquid channel 202 is provided at the bottom of the accommodating cavity 201, so that the functional liquid can flow out of the functional liquid tank 20 by the gravity of the functional liquid itself, thereby helping to reduce the residual liquid in the functional liquid tank 20 to reduce waste.

[0064] In some embodiments, Fig. 9 As shown, a piercing tip 4041 is formed at the upper end of the piercing member 404. The piercing tip 4041 can pierce the pierceable film 2031 more effectively to ensure that when the functional liquid tank 20 is installed in the installation groove 101, the liquid channel 2021 is in a connected state with the third flow path 403.

[0065] In some embodiments, the top of the piercing component 404 is located in the flow channel portion 202. The inlet of the flow channel 405 of the piercing component 404 is located at the top of the piercing component 404. Therefore, if the top of the piercing component 404 extends into the accommodating chamber 201, the inlet of the flow channel 405 may be higher than the liquid channel 2021. In this way, the functional liquid in the functional liquid tank 20 cannot all flow out through the liquid channel 2021, and the residual liquid remaining in the functional liquid tank 20 will eventually cause waste. Therefore, in this embodiment, the top of the piercing component 404 is set to be located in the flow channel portion 202, so that the inlet of the flow channel 405 is located in the liquid channel 2021, thereby reducing the residual liquid in the functional liquid tank 20 and further reducing waste.

[0066] In other embodiments, the top of the piercing component 404 extends into the accommodating cavity 201, and the height of the portion of the piercing component 404 located in the accommodating cavity 201 does not exceed 2 mm. When the top of the piercing component 404 extends into the accommodating cavity 201 and the height of the portion of the piercing component 404 located in the accommodating cavity 201 is limited to not more than 2 mm, in this case, although the problem of residual liquid in the functional liquid tank 20 cannot be eliminated, the amount of residual liquid can be controlled at a lower level, which is also conducive to reducing waste.

[0067] In some embodiments, Figure 6 , Figure 7As shown, the package 203 further includes a soft rubber tube 2032, at least a portion of which is located in the liquid channel 2021 and abuts against the side wall of the liquid channel 2021, and the pierceable film 2031 is arranged inside the soft rubber tube 2032. In this way, when the piercing component 404 extends into the liquid channel 2021 and destroys the pierceable film 2031, the soft rubber tube 2032 is maintained between the piercing component 404 and the side wall of the liquid channel 2021, thereby playing a sealing role to prevent the functional liquid from flowing out from the gap between the piercing component 404 and the side wall of the liquid channel 2021.

[0068] Furthermore, if Figure 3 , Figure 7 , Figure 8 As shown, the inner wall of the soft rubber tube 2032 is provided with a plurality of annular leak-proof protrusions 2033, and the leak-proof protrusions 2033 protrude in the direction close to the central axis of the liquid channel 2021, and the leak-proof protrusions 2033 are used to form a sealing structure with the piercing component 404. When the functional liquid tank 20 is installed in the installation groove 101, the piercing component 404 can pierce the pierceable film 2031 so that the flow channel 405 is connected with the liquid channel 2021. The leak-proof protrusions 2033 are used to form a sealing structure with the piercing component 404. By providing a plurality of annular leak-proof protrusions 2033 on the inner wall of the soft rubber tube 2032, the soft rubber tube 2032 can be more closely contacted with the piercing component 404, so that the sealing effect of the soft rubber tube 2032 can be further improved, thereby better preventing the functional liquid from flowing out from the gap between the piercing component 404 and the side wall of the liquid channel 2021.

[0069] In some embodiments, Fig.10 As shown, a piston 204 is provided inside the functional liquid tank 20, and the piston 204 divides the accommodating chamber 201 into a first chamber 2011 and a second chamber 2012 located below the first chamber 2011. The second chamber 2012 is used to store functional liquid, and a waterproof and breathable membrane is provided on the side wall of the first chamber 2011, and the waterproof and breathable membrane is used to keep the pressure of the first chamber 2011 and the external air environment balanced. With such a configuration, as the amount of functional liquid in the functional liquid tank 20 gradually decreases, the piston 204 will gradually move downward, thereby balancing the pressure of the first chamber 2011 and the second chamber 2012. In this way, the functional liquid in the functional liquid tank can flow out smoothly.

[0070] In some embodiments, the functional liquid tank 20 and the flow channel 202 are made of hard plastic material. This arrangement can ensure that when the piercing component 404 pierces the pierceable film 2031, the functional liquid tank 20 and the flow channel 202 will not be deformed or dented, which is conducive to the smooth piercing of the pierceable film 2031.

[0071] In some embodiments, the cross-sectional area of ​​the mounting groove 101 gradually increases from the bottom of the mounting groove 101 to the opening of the mounting groove 101. In this way, when the functional liquid tank 20 is installed, the functional liquid tank 20 can enter the mounting groove 101 more easily, thereby facilitating the installation efficiency of the functional liquid tank 20.

[0072] In some embodiments, the opening edge of the installation groove 101 is provided with a chamfer structure, so that when the functional liquid tank 20 is installed, it is helpful to make the functional liquid tank 20 enter the installation groove 101 more easily.

[0073] In one of the embodiments, a sealing ring is provided between the functional liquid tank 20 and the inner wall of the mounting groove 101. When the water flosser 1 is working, liquid will splash, and some liquid will flow out along the nozzle 50 of the water flosser 1. If the liquid enters the gap between the inner wall of the mounting groove 101 and the functional liquid tank 20, it will easily breed bacteria and form residual stains over time, which will affect the health and user experience of the user. In this embodiment, a sealing ring is provided between the functional liquid tank 20 and the inner wall of the mounting groove 101, so that a seal can be formed at the gap between the inner wall of the mounting groove 101 and the functional liquid tank 20, thereby preventing liquid from flowing in, so as to improve the problem of easy breeding of bacteria and residual stains.

[0074] In another embodiment, the functional liquid tank 20 is interference fit with the mounting groove 101. In this way, the gap between the inner wall of the mounting groove 101 and the functional liquid tank 20 can be eliminated, thereby preventing liquid from flowing in, thereby improving the problem of easy breeding of bacteria and formation of stains.

[0075] In another embodiment, a cover plate is provided on the top of the installation groove 101. The cover plate can cover the gap between the inner wall of the installation groove 101 and the functional liquid tank 20, so that liquid can be prevented from flowing in, so as to improve the problems of easy breeding of bacteria and formation of stains.

[0076] In some embodiments, Figure 1 , Figure 2 as well as Figure 3As shown, the housing 10 includes a first side portion 103 and a second side portion 104 that are relatively arranged along a first direction, and the first side portion 103 is provided with a key area 1031, and the key area 1031 is provided with a key for controlling the water flosser; along the first direction, the nozzle 50 is located between the mounting groove 101 and the first side portion 103. Among them, the first direction is perpendicular to the height direction of the water flosser 1, that is, the first direction is a horizontal direction. When the user holds the water flosser 1, the thumb can be placed at the position where the key area 1031 is located, and the key area 1031 faces the user, so that the mounting groove 101 is relatively far away from the user, and the water flosser 1 is usually tilted to a certain extent when in use, which makes the mounting groove 101 relatively high. In this way, it is not easy for the water flowing out of the user's mouth to flow to the mounting groove 101, which is conducive to preventing the liquid from flowing into the mounting groove 101, so as to improve the problems of easy breeding of bacteria and formation of stains caused by the liquid flowing into the mounting groove 101.

[0077] Furthermore, the mounting groove 101 is closer to the second side portion 104 than the first side portion 103. In this way, the distance between the mounting groove 101 and the key area 1031 in the horizontal direction can be further increased, so that when the oral irrigator 1 is in use, the water flow from the user's oral cavity is not easy to flow to the mounting groove 101.

[0078] In some embodiments, Figure 1 As shown, the cross-sectional shape of the housing 10 is an ellipse, the cross-sectional shape of the mounting groove 101 is an ellipse, and the major axis of the cross-sectional shape of the housing 10 is parallel to the minor axis of the cross-sectional shape of the mounting groove 101. Accordingly, the cross-sectional shape of the functional liquid tank 20 is an ellipse, so that the cross-sectional shape of the functional liquid tank 20 is adapted to the cross-sectional shape of the mounting groove 101. With such an arrangement, after the functional liquid tank 20 is installed on the housing 10, there is still ample space on the housing 10 for installing the nozzle 50, so that there is no interference between the functional liquid tank 20 and the nozzle 50.

[0079] In some embodiments, Figure 1 , Figure 2 as well as Figure 3 As shown, along the height direction of the oral irrigator 1, the functional liquid tank 20 protrudes from the mounting groove 101, and the height of the functional liquid tank 20 protruding from the mounting groove 101 is greater than or equal to 2.5 mm. With such a configuration, when the user needs to replace the functional liquid tank 20, it is convenient for the user to apply force to the functional liquid tank 20 to remove the functional liquid tank 20 from the mounting groove 101.

[0080] In one embodiment, Figure 6 , Figure 7As shown, the top of the functional liquid tank 20 is provided with a flange 205, or the portion of the functional liquid tank 20 protruding from the mounting groove 101 is provided with a buckle portion. The flange 205 or the buckle portion is convenient for grasping and applying force, so that the disassembly of the functional liquid tank 20 can be made easier and labor-saving.

[0081] In some embodiments, Figure 6 , Figure 7 As shown, a first magnetic member 206 is provided at the bottom of the functional liquid tank 20, and a second magnetic member (not shown in the figure) is provided at the bottom of the mounting groove 101, and the first magnetic member 206 is used to attract the second magnetic member. With such a configuration, when the functional liquid tank 20 is installed in the mounting groove 101, the functional liquid tank 20 can be quickly assembled into place by utilizing the attraction of the first magnetic member 206 and the second magnetic member. In addition, by utilizing the attraction of the first magnetic member 206 and the second magnetic member, the difficulty of the piercing component 404 to pierce the pierceable film 2031 can also be reduced, making the piercing process relatively easier.

[0082] In one embodiment, the first magnetic member 206 is located on the lower surface of the bottom of the functional liquid tank 20. Such a configuration is conducive to reducing the distance between the first magnetic member 206 and the second magnetic member, thereby facilitating the attraction between the first magnetic member 206 and the second magnetic member, thus facilitating the first magnetic member 206 and the second magnetic member to better play the function of assisting puncture, thereby reducing the difficulty of the puncture component 404 in puncturing the puncturable film 2031.

[0083] In one embodiment, the lower surface of the bottom of the functional liquid tank 20 is provided with an upwardly concave groove 207, and at least a portion of the first magnetic member 206 is located in the groove 207. By disposing at least a portion of the first magnetic member 206 in the groove 207, the overall thickness of the bottom structure of the functional liquid tank 20 can be reduced, thereby improving the problem of the overall height of the functional liquid tank 20 being too high due to the provision of the first magnetic member 206.

[0084] Furthermore, the first magnetic member 206 is completely embedded in the groove 207. This arrangement can further reduce the overall thickness of the bottom structure of the functional liquid tank 20, thereby better improving the problem of the overall height of the functional liquid tank 20 being too high due to the arrangement of the first magnetic member 206.

[0085] In one embodiment, the first magnetic member 206 is an annular structure and surrounds the flow channel portion 202, and the second magnetic member is an annular structure. It is understandable that when the functional liquid tank 20 is installed in the installation groove 101, the second magnetic member also surrounds the flow channel portion 202. In this embodiment, the first magnetic member 206 is an annular structure and surrounds the flow channel portion 202, and the second magnetic member is an annular structure. Such an arrangement is conducive to making the magnetic force received by the functional liquid tank 20 more evenly distributed, so that when the functional liquid tank 20 is installed, it is conducive to avoiding the functional liquid tank 20 from being offset or skewed.

[0086] In some embodiments, Figure 4 , Figure 5 As shown, the oral irrigator 1 further includes a second liquid pump 70, which is disposed in the mounting cavity 102 and in the third flow path 403. The first liquid pump 30 is the main power device of the oral irrigator 1, and the second liquid pump 70 can provide auxiliary power for the output of the functional liquid. The second liquid pump 70 can transport the functional liquid in the functional liquid tank 20 to the first flow path 401 or the second flow path 402, and then use the power of the first liquid pump 30 to pump the functional liquid out of the nozzle 50, so that the oral irrigator 1 can have more sufficient power.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
