[0054] 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 the water flosser, a water flosser in the related art is equipped with a functional liquid bottle, which contains a functional liquid with specific effects (such as sterilization, fresh breath, etc.).

[0055] When installing the functional liquid bottle in the related art to the oral irrigator, it is necessary to open the bottle mouth first, and then install the functional liquid bottle upside down (with the bottle mouth facing downward) on the oral irrigator. During the installation process, it is inevitable that a small amount of liquid will flow out, causing waste.

[0056] Based on this, the present application provides a functional liquid bottle and a water flosser having the functional liquid bottle, aiming to improve the problem that the functional liquid bottle is easily prone to liquid outflow when being installed on the water flosser.

[0057] like Figures 1 to 5As shown, the functional liquid bottle 200 in the embodiment of the first aspect of the present application includes a bottle body 210, a bottle bottom 220 and a packaging member 230. The bottle bottom 220 is connected to the bottle body 210, and the bottle body 210 and the bottle bottom 220 jointly define a receiving chamber 201 for receiving the functional liquid. The bottom of the bottle bottom 220 is provided with a downwardly extending flow channel portion 240, and the inside of the flow channel portion 240 is provided with a liquid channel 241 communicating with the receiving chamber 201. The bottom of the flow channel portion 240 is provided with a channel opening 242 communicating with the liquid channel 241, and the inner diameter of the liquid channel 241 is smaller than the inner diameter of the receiving chamber 201. The packaging member 230 seals the liquid channel 241, and the packaging member 230 includes a puncturable film 231, and the puncturable film 231 is located in the liquid channel 241.

[0058] Specifically, the bottle body 210 and the bottle bottom 220 of the functional liquid bottle 200 define a receiving chamber 201 together, and the receiving chamber 201 can be used to receive functional liquid, wherein the functional liquid is, for example, a liquid having functions of sterilization, fresh breath, and treatment of inflammation. The flow channel portion 240 located at the bottle bottom 220 constructs a channel for outputting the functional liquid, that is, the functional liquid can be output through the liquid channel 241 in the flow channel portion 240, thereby providing the functional liquid to the water flosser 100.

[0059] The packaging member 230 can seal the liquid channel 241, so that the functional liquid bottle 200 has a good sealing effect when not in use, so as to ensure that the functional liquid in the accommodating cavity 201 will not be contaminated or volatilized. The packaging member 230 includes a puncturable film 231, which can be punctured relatively easily. When the puncturable film 231 is punctured, the packaging member 230 loses its sealing effect, and at this time, the liquid channel 241 becomes unobstructed.

[0060] It is understood that the internal part of the water flosser 100 is provided with a liquid supply flow path, which is connected to the liquid pump in the water flosser 100. After the functional liquid bottle 200 is installed on the water flosser 100, the liquid channel 241 in the flow channel part 240 is connected to the liquid supply flow path of the water flosser 100, so that the functional liquid bottle 200 can be used to supply the functional liquid to the water flosser 100. In addition, the water flosser 100 is also provided with a piercing component 110 (refer to Fig. 9 and Fig.10 ), the piercing component 110 is provided with a flow channel 111 inside, and the flow channel 111 forms a part of the liquid supply flow path. In this way, when the functional liquid bottle 200 is installed on the dental flosser 100, the piercing component 110 can destroy the pierceable film 231, and the flow channel 111 in the piercing component 110 is connected with the liquid channel 241.

[0061] The functional liquid bottle 200 in the embodiment of the present application can be applied to the oral irrigator 100. The bottom 220 of the functional liquid bottle 200 is provided with a flow channel 240. The liquid channel 241 in the flow channel 240 can be used to output the functional liquid in the accommodating cavity 201. The functional liquid bottle 200 is also provided with a package 230, which seals the liquid channel 241, wherein the package 230 includes a puncturable film 231 located in the liquid channel 241. The functional liquid bottle 200 can be applied to the oral irrigator 100 provided with a puncture component 110. When the functional liquid bottle 200 is installed on the oral irrigator 100, the puncture component 110 on the oral irrigator 100 extends into the liquid channel 241 and punctures the puncturable film 231, thereby connecting the liquid channel 241 with the liquid supply path in the oral irrigator 100. This installation method can significantly improve the problem of liquid outflow during the installation of the functional liquid bottle 200. In addition, when the piercing component 110 extends into the liquid channel 241 to pierce the pierceable film 231, the flow channel portion 240 can play a guiding role, making the pierceable film 231 easier to pierce, thereby improving the success rate of piercing.

[0062] In some embodiments, Figure 3 , Figure 4 as well as Figure 5 As shown, the packaging member 230 further includes a soft rubber tube 232, at least a portion of which is located in the liquid channel 241 and abuts against the side wall of the liquid channel 241, and the puncturable film 231 is arranged inside the soft rubber tube 232. In this way, when the puncture component 110 on the dental flosser 100 is inserted into the liquid channel 241 and the puncturable film 231 is destroyed, the soft rubber tube 232 is maintained between the puncture component 110 and the side wall of the liquid channel 241, thereby playing a sealing role to prevent the functional liquid from flowing out from the gap between the puncture component 110 and the side wall of the liquid channel 241.

[0063] In some embodiments, the distance from the pierceable film 231 to the upper end of the liquid channel 241 is greater than 1 / 4 of the length of the liquid channel 241 along the height direction of the functional liquid bottle 200 .

[0064] It is easy to understand that the top of the piercing component 110 is provided with a piercing tip 112 (refer to Fig. 9 and Fig.10 ), so that the puncturable film 231 can be destroyed. If the distance between the puncturable film 231 and the upper end of the liquid channel 241 is small, the puncturing tip 112 may extend into the accommodating cavity 201, and the inlet of the flow channel 111 is usually arranged at the top of the puncturing component 110, which makes the inlet of the flow channel 111 higher than the liquid channel 241. In this way, the functional liquid in the functional liquid bottle 200 cannot flow out through the liquid channel 241, and the residual liquid remaining in the functional liquid bottle 200 will eventually lead to waste.

[0065] In this embodiment, the distance from the pierceable film 231 to the upper end of the liquid channel 241 is greater than 1 / 4 of the length of the liquid channel 241 along the height direction of the functional liquid bottle 200. In this way, after the piercing component 110 destroys the pierceable film 231, the piercing tip 112 can be ensured to be in the liquid channel 241, so that the inlet of the flow channel 111 is located in the liquid channel 241, so that the residual liquid can be reduced.

[0066] In some embodiments, Figure 3 , Figure 4 as well as Figure 5 As shown, the puncturable film 231 and the soft rubber tube 232 are of an integrated structure and made of the same material, and the thickness of the puncturable film 231 is less than the wall thickness of the soft rubber tube 232. The puncturable film 231 and the soft rubber tube 232 are made of the same material and are made in an integrated manner, which is conducive to improving the sealing performance of the seal. In addition, the thickness of the puncturable film 231 is set to be less than the thickness of the soft rubber tube 232, so that the difficulty of destroying the puncturable film 231 can be reduced, so that the puncturable film 231 is easily destroyed by the puncture component 110.

[0067] In some embodiments, Figure 3 , Figure 4 as well as Figure 5 As shown, the inner wall of the soft rubber tube 232 is provided with a plurality of annular leak-proof protrusions 2321, and the leak-proof protrusions 2321 protrude in the direction close to the central axis of the liquid channel 241. The water flosser 100 includes a puncturing component 110, and a flow channel 111 is formed inside the puncturing component 110. When the functional liquid bottle 200 is installed on the water flosser 100, the puncturing component 110 can puncture the puncturable film 231 so that the flow channel 111 is connected with the liquid channel 241. The leak-proof protrusions 2321 are used to form a sealing structure with the puncturing component 110. By providing a plurality of annular leak-proof protrusions 2321 on the inner wall of the soft rubber tube 232, the soft rubber tube 232 can be made to contact the puncturing component 110 more closely, so that the sealing effect of the soft rubber tube 232 can be further improved, thereby better preventing the functional liquid from flowing out of the gap between the puncturing component 110 and the side wall of the liquid channel 241.

[0068] In some embodiments, the leak-proof protrusion 2321 is located below the pierceable film 231, so that when the piercing component 110 destroys the pierceable film 231, the leak-proof protrusion 2321 will be in close contact with the piercing component 110, thereby effectively performing a sealing function.

[0069] In some embodiments, Figure 3 , Figure 4 as well as Figure 5As shown, the upper end of the soft rubber tube 232 is provided with a first flange 2322, the first flange 2322 protrudes in a direction away from the central axis of the liquid channel 241, and the first flange 2322 is located in the accommodating cavity 201 and abuts against the top surface of the bottle bottom 220. The mutual abutment between the first flange 2322 and the top surface of the bottle bottom 220 can improve the connection stability between the soft rubber tube 232 and the flow channel portion 240, thereby preventing the soft rubber tube 232 from moving relative to the flow channel portion 240 along the axial direction of the liquid channel 241.

[0070] Furthermore, the distance between the end surface of the upper end of the soft rubber tube 232 and the top surface of the bottle bottom 220 does not exceed 3 mm. If the distance between the end surface of the upper end of the soft rubber tube 232 and the top surface of the bottle bottom 220 is too large, it is easy to increase the residual liquid in the functional liquid bottle 200. Therefore, the embodiment of the present application sets the above distance to be no more than 3 mm, so that while improving the connection stability between the soft rubber tube 232 and the flow channel portion 240, it is helpful to reduce the residual liquid in the functional liquid bottle 200.

[0071] In some embodiments, Figure 3 , Figure 4 as well as Figure 5 As shown, the inner wall of the flow channel 240 is formed with a step portion 243, and the outer wall of the soft rubber tube 232 is formed with a second flange 2323, the second flange 2323 protrudes in a direction away from the central axis of the liquid channel 241, and the second flange 2323 is clamped to the step portion 243. The clamping between the second flange 2323 and the step portion 243 can improve the combination stability between the soft rubber tube 232 and the flow channel 240, thereby preventing the soft rubber tube 232 from moving relative to the flow channel 240 along the axis direction of the liquid channel 241. In some other embodiments, the soft rubber tube 232 and the bottle bottom 220 are an integrally formed structure, so that the combination stability between the soft rubber tube 232 and the flow channel 240 can also be improved.

[0072] In some embodiments, Figure 3 , Figure 4 as well as Figure 5 As shown, the lower end of the soft rubber tube 232 is provided with a tube chamfer 2324. In this way, it is convenient for the piercing component 110 to enter the soft rubber tube so as to pierce the pierceable film 231 in the soft rubber tube 232.

[0073] In some embodiments, the bottle bottom 220 is made of hard plastic material. This arrangement ensures that the bottle bottom 220 will not be deformed or dented when the piercing component 110 pierces the pierceable film 231, thereby ensuring that the pierceable film 231 is pierced smoothly.

[0074] In some embodiments, the bottle body 210 is made of hard plastic. On the one hand, it can make the installation and replacement of the functional liquid bottle 200 easier. On the other hand, as the amount of functional liquid in the functional liquid bottle 200 gradually decreases, the pressure inside the functional liquid bottle 200 will decrease. The bottle body 210 is made of hard plastic, which can ensure that when the pressure inside the functional liquid bottle 200 decreases, the bottle body 210 will not be deformed. The advantage of this is that it can avoid the formation of a large gap between the bottle body 210 and the wall of the mounting groove on the water flosser 100 (the functional liquid bottle 200 is installed in the mounting groove), thereby preventing dirt and water from entering.

[0075] In some embodiments, the cross-sectional shape of the bottle body 210 is an ellipse. When the functional liquid bottle 200 is installed on the water flosser 100, the short axis of the ellipse can point to the nozzle of the water flosser 100, that is, the nozzle can be located on the extension line of the short axis of the ellipse. In this way, after the functional liquid bottle 200 is installed, the nozzle can also have a relatively ample installation space.

[0076] In some embodiments, Figure 3 , Figure 5 As shown, a first magnetic member 250 is provided at the bottom of the bottle bottom 220. Accordingly, the oral irrigator 100 includes a second magnetic member, and the first magnetic member 250 is used to attract the second magnetic member. With such a configuration, when the functional liquid bottle 200 is installed on the oral irrigator 100, the functional liquid bottle 200 can be quickly assembled into place by utilizing the attraction of the first magnetic member 250 and the second magnetic member. In addition, by utilizing the attraction of the first magnetic member 250 and the second magnetic member, the difficulty of the piercing component 110 to pierce the pierceable film 231 can also be reduced, making the piercing process relatively easier.

[0077] In some embodiments, Figure 3 , Figure 5 As shown, the bottle bottom 220 includes a main body 221, the flow channel 240 is connected to the main body 221, the top of the main body 221 is provided with an abutting surface, and the lower end of the bottle body 210 abuts against the abutting surface. The bottle bottom 220 also includes a positioning protrusion 222, which is located at the top of the main body 221, and the positioning protrusion 222 extends into the interior of the bottle body 210 and abuts against the inner wall of the bottle body 210.

[0078] The bottle body 210 and the bottle bottom 220 can be connected by gluing. The bottle bottom 220 is provided with a positioning protrusion 222, which can extend into the inner wall of the bottle body 210 and abut against the inner wall of the bottle body 210. In this way, during the curing process of the glue, the positioning protrusion 222 can prevent the bottle body 210 from being offset relative to the bottle bottom 220, thereby facilitating the assembly accuracy of the bottle body 210 and the bottle bottom 220.

[0079] Furthermore, if Figure 5 As shown, the main body 221 has a peripheral side surface 2211 and a bottom surface 2212, and there is a smooth transition between the peripheral side surface 2211 and the bottom surface 2212. In this way, when the functional liquid bottle 200 is installed in the installation groove of the dental flosser 100, the functional liquid bottle 200 can enter the installation groove more easily.

[0080] In some embodiments, Figure 2 As shown, the top of the bottle body 210 is provided with a third flange 211, or a buckle portion is provided on the outer surface of the bottle body 210. The third flange 211 or the buckle portion is convenient for grasping and applying force, so that the functional liquid bottle 200 can be disassembled and assembled more easily.

[0081] In some embodiments, Figure 6 As shown, the functional liquid bottle 200 also includes a piston 260 located in the accommodating chamber 201, and the piston 260 divides the accommodating chamber 201 into a first chamber 2011 and a second chamber 2012 located below the first chamber 2011, and the second chamber 2012 is used to store the functional liquid. The side wall of the first chamber 2011 is provided with a waterproof and breathable membrane, and the waterproof and breathable membrane is used to keep the pressure of the first chamber 2011 and the external air environment balanced. In this way, as the amount of functional liquid in the functional liquid bottle 200 decreases, the piston 260 will gradually move down to balance the pressure of the first chamber 2011 and the second chamber 2012.

[0082] Second, as Figure 7 , Figure 8 as well as Fig. 9 As shown, the present application provides a water flosser 100, which includes the functional liquid bottle 200 in any of the above embodiments.

[0083] The oral irrigator 100 in the embodiment of the present application is based on the same inventive concept as the functional liquid bottle 200 in the above-mentioned first embodiment. Therefore, the oral irrigator in the embodiment of the present application can obtain the beneficial effects of the functional liquid bottle 200 in the above-mentioned embodiment.

[0084] In some embodiments, Fig. 9 As shown, the oral irrigator 100 includes a housing 120, a mounting groove 121 is formed on the top of the housing 120, and the functional liquid bottle 200 is detachably mounted in the mounting groove 121. Thus, the functional liquid bottle 200 can be mounted on the top of the housing 120 of the oral irrigator 100.

[0085] In some embodiments, a sealing ring is provided between the bottle body 210 and the inner wall of the mounting groove 121, or the bottle body 210 and the mounting groove 121 are interference fit. When the water flosser 100 is working, liquid will splash, and some liquid will flow out along the nozzle of the water flosser 100. If the fluid enters the gap between the inner wall of the mounting groove 121 and the functional liquid bottle 200, it will easily breed bacteria and form stains over time, which will affect the user's health and use experience. In this embodiment, a sealing ring is provided between the bottle body 210 and the inner wall of the mounting groove 121, or the bottle body 210 and the mounting groove 121 are interference fit, so that the gap between the inner wall of the mounting groove 121 and the functional liquid bottle 200 can be eliminated, thereby avoiding the inflow of liquid, which may easily breed bacteria, form stains, and other problems.

[0086] In some embodiments, Fig. 9 , Fig.10 As shown, the dental flosser 100 further includes a piercing component 110, which is disposed below the mounting groove 121. A flow channel 111 is formed inside the piercing component 110. When the functional liquid bottle 200 is installed in the mounting groove 121, the piercing component 110 can pierce the pierceable film 231 to connect the flow channel 111 with the liquid channel 241.

[0087] It is understandable that the oral irrigator 100 can be provided with a liquid supply flow path, which is connected to the liquid pump in the oral irrigator 100. After the functional liquid bottle 200 is installed on the oral irrigator 100, the liquid channel 241 in the flow channel portion 240 is connected to the liquid supply flow path of the oral irrigator 100, so that the functional liquid bottle 200 can be used to supply the functional liquid to the oral irrigator 100. The oral irrigator 100 is provided with a puncture component 110, and the puncture component 110 is provided with a flow channel 111 inside, and the flow channel 111 forms a part of the liquid supply flow path. In this way, when the functional liquid bottle 200 is installed on the oral irrigator 100, the puncture component 110 can destroy the puncturable film 231, and the flow channel 111 in the puncture component 110 is connected to the liquid channel 241.

[0088] The above contents are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. 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. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
