Description

Technical Field

[0001] The present application relates to the technical field of oral cleaning equipment, and in particular to a water flosser. Background Art

[0002] Oral irrigators usually use water as the flushing medium, removing dental plaque on the tooth surface and food debris between the teeth through the impact force of water. However, simply using water as a medium to clean the oral cavity cannot kill bacteria in the oral cavity, remove bad breath, or keep the breath fresh.

[0003] Although some oral irrigators have other tanks outside the water tank for storing liquids such as mouthwash to enable the irrigator to achieve more functions, the pump body of the oral irrigator is mainly used to extract the liquid in the water tank, and the suction effect on the liquid in the other tanks is weak, resulting in the liquid in the water tank flowing out quickly while the liquid in the other tanks flowing out slowly.

[0043] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0044] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0047] The oral irrigator 1 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0048] like Figure 2-Figure 4 , Figure 8 and Fig. 9 As shown, the oral irrigator 1 of the embodiment of the present application includes a nozzle 100, a water tank 200, a first pump body 400, a functional liquid tank 500, a first hard tube 800, a second hard tube 510 and a connecting tube 600.

[0049] The nozzle 100 is provided with a liquid spraying port 101, and the water tank 200 is connected to the liquid spraying port 101 through an infusion flow path 300. The water tank 200 can be used to store water. The first pump body 400 is arranged in the infusion flow path 300, and the first pump body 400 is used to pump the liquid in the water tank 200 to the liquid spraying port 101 through the infusion flow path 300.

[0050] For example, the first pump body 400 may be a plunger pump or a diaphragm pump. Since the plunger pump and the diaphragm pump are positive displacement pump bodies, the positive displacement pump body can isolate the liquid inlet and the liquid outlet when it stops running, so that the first pump body 400 can prevent the liquid in the infusion flow path 300 from flowing back. In addition, the dental flosser 1 also includes a battery 930 and an electric control board 940, and the battery 930 and the electric control board 940 are both connected to the first pump body 400.

[0051] The first hard tube 800 is provided with a first interface 810 and a second interface 820, the first interface 810 is connected to the infusion flow path 300, the second hard tube 510 is provided with a third interface 511 and a fourth interface 512, the third interface 511 is connected to the functional liquid tank 500, the second interface 820 and the fourth interface 512 are connected through a connecting tube 600, and the liquid in the functional liquid tank 500 flows to the infusion flow path 300 through the second hard tube 510, the connecting tube 600 and the first hard tube 800. The functional liquid tank 500 contains functional liquid, and the liquid in the functional liquid tank 500 is different from the liquid in the water tank 200. For example, the functional liquid tank 500 can be used to store functional liquids with different functions such as mouthwash, cleaning liquid, and medicine liquid. The liquid in the functional liquid tank 500 can achieve at least one of the functions of sterilization, deodorization, tartar removal, and teeth whitening.

[0052] For example, the connecting tube 600 is a hose, the hardness of the first hard tube 800 and the hardness of the second hard tube 510 are both greater than the hardness of the connecting tube 600, and the shapes of the first hard tube 800 and the second hard tube 510 are not easy to change, which can be used to ensure the position and shape of the end of the connecting tube 600, thereby limiting the approximate flow path of the functional fluid. The connecting tube 600 can be made of flexible materials such as thermoplastic elastomer (Thermoplastic Elastomer, TPE), polyethylene (Polyethylene, PE), etc., so that the connecting tube 600 is easy to deform, and the connecting tube 600 can change its own shape according to the different layouts in the water flosser 1. Therefore, the connecting tube 600 can be suitable for water flossers 1 with different structures. The connecting tube 600 is more adaptable, which is conducive to the assembly of the connecting tube 600.

[0053] In this way, the functional liquid and the water liquid are mixed in the infusion flow path 300 to form a mixed liquid, which is sprayed out from the spray port 101. Not only can the impact force of the mixed liquid remove dental plaque on the tooth surface and food residues between the teeth, but the mixed liquid also has additional functions, such as killing oral bacteria, removing bad breath, keeping breath fresh, and whitening teeth. Users can add functional liquids with different functions into the functional liquid tank 500 according to their needs.

[0054] The second interface 820 extends toward the second rigid tube 510 , or the fourth interface 512 extends toward the first rigid tube 800 , or the second interface 820 extends toward the second rigid tube 510 and the fourth interface 512 extends toward the first rigid tube 800 .

[0055] In this way, the length of the connecting tube 600 can be shortened, thereby shortening the path length of the functional fluid flowing to the infusion path 300, allowing the functional fluid to quickly enter the infusion path 300, shortening the pumping time of the functional fluid, and allowing the functional fluid to be discharged more quickly.

[0056] like Figure 7 As shown, the above-mentioned infusion flow path 300 includes a first flow path 310 and a second flow path 320. The first flow path 310 is located between the first pump body 400 and the water tank 200, and the second flow path 320 is located between the first pump body 400 and the liquid spray port 101. The first interface 810 is connected to the first flow path 310.

[0057] That is to say, in the extension direction of the infusion flow path 300, the first flow path 310 is located upstream of the first pump body 400, and the second flow path 320 is located downstream of the first pump body 400. When the first interface 810 is connected to the first flow path 310, the first interface 810 is also located upstream of the first pump body 400. Therefore, the functional liquid and the aqueous liquid are mixed upstream of the first pump body 400. The path through which the functional liquid and the aqueous liquid flow after mixing is long, the functional liquid and the aqueous liquid are mixed for a long time, and the functional liquid and the aqueous liquid are mixed more fully and evenly, which is beneficial to ensure the cleaning effect of the liquid sprayed from the spray port 101 on various areas of the teeth.

[0058] like Figure 5-Figure 6 As shown, the above-mentioned infusion flow path 300 includes a first flow path 310 and a second flow path 320. The first flow path 310 is located between the first pump body 400 and the water tank 200, and the second flow path 320 is located between the first pump body 400 and the liquid spray port 101. The first interface 810 is connected to the second flow path 320.

[0059] That is to say, in the extension direction of the infusion flow path 300, the first flow path 310 is located upstream of the first pump body 400, and the second flow path 320 is located downstream of the first pump body 400. When the first interface 810 is connected to the second flow path 320, the first interface 810 is also located downstream of the first pump body 400. Therefore, the functional liquid and the aqueous liquid are mixed downstream of the first pump body 400, and the functional liquid will not flow through the first pump body 400, thereby reducing the probability of the first pump body 400 being corroded by the functional liquid, and the mixed liquid needs to flow through a shorter path to flow to the liquid injection port 101, and the flow path of the functional liquid is shorter, so it can be sprayed out faster.

[0060] like Figure 8-Figure 9As shown, when the first interface 810 is connected to the first flow path 310, the first hard tube 800 is connected to the liquid inlet of the first pump body 400. In this way, there is no need to set up an additional pipeline connection between the first hard tube 800 and the first pump body 400, which can reduce the number of pipelines, and the connection between the first hard tube 800 and the first pump body 400 is more convenient, shortening the distance of the functional liquid flowing to the liquid injection port 101.

[0061] like Figure 8-Figure 9 As shown, when the first interface 810 is connected to the first flow path 310, the first hard tube 800 is further provided with a fifth interface 830, and the fifth interface 830 is connected to the water tank 200. The first hard tube 800 may be a three-way tube, a four-way tube, or the like.

[0062] By providing the fifth interface 830 on the first hard tube 800, the water tank 200, the first pump body 400 and the functional liquid tank 500 can be connected to each other, which is beneficial to ensuring the connection reliability between the functional liquid tank 500 and the infusion path 300, reducing the number of parts and making the structure simpler.

[0063] like Figure 5-Figure 6 As shown, when the first interface 810 is connected to the second flow path 320, the first hard tube 800 and the nozzle 100 are spaced apart in the extension direction of the second flow path 320. Since the functional liquid in the functional liquid tank 500 needs to first flow through the second hard tube 510, the connecting tube 600 and the first hard tube 800, and then flow through the infusion flow path 300, and then be sprayed out from the spray port 101, by spacing the first hard tube 800 and the nozzle 100, that is, the functional liquid and the water liquid have already begun to mix before flowing into the nozzle 100. In the extension direction of the infusion flow path 300, the functional liquid flows from the first hard tube 800 to the spray port 101 and at least flows through the flow channel in the nozzle 100. When flowing to the spray port 101, the functional liquid and the water liquid are mixed more evenly, which is conducive to ensuring the cleaning effect of the liquid sprayed from the spray port 101 on various areas of the teeth.

[0064] like Figure 5-Figure 6 As shown, the second flow path 320 has a mixing chamber 321, and the area surrounded by the inner contour of the cross section of the mixing chamber 321 is larger than the area surrounded by the inner contour of the cross section of the rest of the second flow path 320. In the extending direction of the second flow path 320, the mixing chamber 321 is located downstream of the first hard tube 800, or the positions of the mixing chamber 321 and the first hard tube 800 correspond.

[0065] Specifically, the functional liquid in the functional liquid tank 500 needs to first flow through the second hard tube 510, the connecting tube 600 and the first hard tube 800, and then flow through the mixing chamber 321 before it can flow to the liquid spraying port 101 and be sprayed out from the liquid spraying port 101. Since the area surrounded by the inner contour of the cross section of the mixing chamber 321 is large, the flow rate of the liquid in the mixing chamber 321 is slow, so the functional liquid stays in the mixing chamber 321 for a longer time, and the water liquid and the functional liquid in the mixing chamber 321 can fully contact and mix, which is conducive to mixing the functional liquid and the water liquid to form a uniform mixed liquid.

[0066] In addition, the mixed liquid continues to flow from the mixing chamber 321 toward the liquid spray port 101. Since the inner diameter of the pipe between the mixing chamber 321 and the liquid spray port 101 gradually decreases, the flow rate of the mixed liquid gradually increases, and the impact force of the liquid sprayed from the liquid spray port 101 is stronger, which is beneficial to the cleaning of teeth.

[0067] like Figure 2 As shown, the first pump body 400 includes a pumping component 410 and a motor 420. The pumping component 410 is arranged in the infusion flow path 300, and the first hard tube 800 is connected to the pumping component 410. The motor 420 is arranged in the infusion flow path 300 and connected to the pumping component 410, and the motor 420 is used to drive the pumping component 410 to pump the liquid in the water tank 200 to the liquid spraying port 101 through the infusion flow path 300. Among them, the first pump body 400 and the functional liquid tank 500 are arranged in parallel, and the pumping component 410 is closer to the functional liquid tank 500 than the motor 420.

[0068] For example, the motor 420 and the pumping component 410 can be arranged along the length direction of the oral irrigator 1, or the motor 420 and the pumping component 410 can be arranged along the radial direction of the oral irrigator 1. In addition, the motor 420 outputs power through the motor 420 shaft to drive the pumping component 410 to change its volume. When the volume of the pumping component 410 increases, water is extracted from the water tank 200. When the volume of the pumping component 410 decreases, the liquid in the infusion flow path 300 is squeezed to the liquid spraying port 101 and sprayed out from the liquid spraying port 101.

[0069] By placing the functional liquid tank 500 closer to the pump liquid component 410, that is, the functional liquid tank 500 is closer to the first hard tube 800 and the infusion flow path 300, the pipe length between the functional liquid tank 500 and the first hard tube 800 can be shortened, thereby shortening the flow path of the functional liquid in the functional liquid tank 500 in the process of flowing to the infusion flow path 300, so that the functional liquid in the functional liquid tank 500 can flow to the infusion flow path 300 more quickly.

[0070] like Figure 8-Figure 9As shown, the spacing between the second interface 820 and the fourth interface 512 in the length direction of the oral irrigator 1 is not greater than 10 mm. Among them, the spacing between the second interface 820 and the fourth interface 512 in the length direction of the oral irrigator 1 refers to the spacing between the center of the second interface 820 and the center of the fourth interface 512 in the length direction of the oral irrigator 1. It should be noted that the second interface 820 can be in a rectangular, triangular, circular or other shape, and the fourth interface 512 can be in a rectangular, triangular, circular or other shape. For example, when the second interface 820 is circular and the fourth interface 512 is circular, the spacing between the center of the second interface 820 and the center of the fourth interface 512 in the length direction of the oral irrigator 1 is not greater than 10 mm.

[0071] For example, in the length direction of the oral irrigator 1, the spacing between the second interface 820 and the fourth interface 512 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, or 10mm.

[0072] In addition, during the use of the oral irrigator 1, the second interface 820 can be located above the fourth interface 512, that is, the second interface 820 is closer to the nozzle 100 relative to the fourth interface 512, or during the use of the oral irrigator 1, the second interface 820 can be located below the fourth interface 512, that is, the fourth interface 512 is closer to the nozzle 100 relative to the second interface 820.

[0073] In this way, the second interface 820 and the fourth interface 512 are closer in the length direction of the oral irrigator 1, which is beneficial to reducing the size of the pipeline between the second interface 820 and the fourth interface 512, thereby shortening the flow path of the functional liquid in the functional liquid tank 500 to the infusion path 300, so that the functional liquid in the functional liquid tank 500 can flow to the infusion path 300 more quickly.

[0074] like Figure 2-Figure 3 , Figure 5-Figure 7 As shown, in the length direction of the water flosser 1, a liquid outlet 520 is provided on the side of the functional liquid tank 500 facing the water tank 200. During the use of the water flosser 1, generally speaking, the water tank 200 is at the lower end of the water flosser 1. By setting the liquid outlet 520 on the side of the functional liquid tank 500 facing the water tank 200, the functional liquid in the functional liquid tank 500 can naturally flow to the liquid outlet 520 under the action of gravity, and the amount of functional liquid remaining in the functional liquid tank 500 is reduced, which is beneficial to improve the utilization rate of the functional liquid.

[0075] In addition, the third interface 511 is connected to the liquid outlet 520, and the central axis of the fourth interface 512 is perpendicular to the central axis of the liquid outlet 520. In other words, the central axis of the third interface 511 can coincide with the central axis of the liquid outlet 520, the central axis of the fourth interface 512 is perpendicular to the central axis of the third interface 511, and the functional liquid can turn 90 degrees in the second hard tube 510.

[0076] like Figure 8-Figure 9 As shown, the central axis of the second interface 820, the central axis of the fourth interface 512 and the length direction of the oral irrigator 1 are perpendicular to each other. In this way, while the second interface 820 and the fourth interface 512 are close to each other, the second interface 820 and the fourth interface 512 are not arranged relative to each other, and the second interface 820 and the fourth interface 512 are arranged in a staggered manner in space, which can utilize the space at different positions of the oral irrigator 1 and improve the space utilization rate of the oral irrigator 1.

[0077] Since the central axis of the second interface 820 does not extend along the length direction of the oral irrigator 1, it is convenient for the central axis of the fifth interface 830 to extend along the length direction of the oral irrigator 1. In this way, the fifth interface 830 is more convenient to connect with the water tank 200, the pipe between the fifth interface 830 and the water tank 200 has fewer bends, and the flow of liquid in the pipe between the fifth interface 830 and the water tank 200 is more convenient.

[0078] Since the central axis of the fourth interface 512 does not extend along the length direction of the oral irrigator 1, the central axis of the third interface 511 is convenient to extend along the length direction of the oral irrigator 1, so that the third interface 511 is more convenient to connect with the liquid outlet 520 of the functional liquid tank 500, and the flow of functional liquid between the third interface 511 and the functional liquid tank 500 is more convenient.

[0079] The above-mentioned oral irrigator 1 further includes a movement 910, which defines at least a portion of the infusion flow path 300, a first hard tube 800 connected to the movement 910, a first interface 810 exposed from the movement 910, a second hard tube 510 located outside the movement 910, and at least a portion of the connecting tube 600 located outside the movement 910. The portion of the connecting tube 600 located outside the movement 910 is connected to the first hard tube 800, or the portion of the connecting tube 600 located outside the movement 910 is connected to the second hard tube 510, or the portion of the connecting tube 600 located outside the movement 910 is connected to the first hard tube 800 and the second hard tube 510.

[0080] In this way, after the first hard tube 800 is connected to the movement 910, the connecting tube 600 can be plugged in and out from the outside of the movement 910 and the first hard tube 800, and the second hard tube 510 can also be plugged in and out from the outside of the movement 910 and the connecting tube 600. The connection between the connecting tube 600, the first hard tube 800 and the second hard tube 510 is not restricted by the movement 910, which facilitates the disassembly and assembly of the connecting tube 600, and the assembly and subsequent maintenance of the oral irrigator 1 are more convenient.

[0081] like Figure 8-Figure 9 As shown, the above-mentioned water flosser 1 also includes a second pump body 700, and the second pump body 700 has a sixth interface 710 and a seventh interface 720, the sixth interface 710 is connected to the second interface 820, and the seventh interface 720 is connected to the fourth interface 512, wherein the connecting pipe 600 includes a first pipe 610 and a second pipe 620, the second interface 820 and the fourth interface 512 are connected through the first pipe 610, and the fourth interface 512 and the seventh interface 720 are connected through the second pipe 620.

[0082] By adding a second pump body 700 and adjusting the power of the second pump body 700, the speed and frequency of the functional liquid in the functional liquid tank 500 flowing to the infusion path 300 can be controlled, and the second pump body 700 can be a positive displacement pump body such as a diaphragm pump, a plunger pump and a peristaltic pump. The positive displacement pump body can isolate the liquid inlet and the liquid outlet 520 when it stops running, so that the second pump body 700 can prevent the liquid in the infusion path 300 from flowing back to the functional liquid tank 500, avoiding leakage and backflow of the functional liquid, and there is no need to additionally set a one-way valve between the second interface 820 and the fourth interface 512, thereby reducing costs and the number of parts.

[0083] The sixth interface 710 extends toward the second interface 820, and the seventh interface 720 extends toward the fourth interface 512. In this way, the lengths of the first pipeline 610 and the second pipeline 620 can be shortened, thereby shortening the flow path of the functional liquid in the functional liquid tank 500 in the process of flowing to the infusion flow path 300, so that the functional liquid in the functional liquid tank 500 can flow to the infusion flow path 300 more quickly.

[0084] like Figure 8-Figure 9 As shown, in the circumferential direction of the oral irrigator 1, the second pump body 700 is located between the second interface 820 and the fourth interface 512, and the sixth interface 710 and the seventh interface 720 are arranged along the circumferential direction of the oral irrigator 1, and the sixth interface 710 is closer to the second interface 820 than the seventh interface 720. Among them, the central axis of the sixth interface 710 and the central axis of the seventh interface 720 are arranged in parallel and extend along the length direction of the oral irrigator 1, and thus the portion of the first pipe 610 extending along the length direction of the oral irrigator 1 and the portion of the second pipe 620 extending along the length direction of the oral irrigator 1 can be arranged parallel to each other.

[0085] In this way, on the circumference of the oral irrigator 1, the sum of the distance between the sixth interface 710 and the second interface 820 and the distance between the seventh interface 720 and the fourth interface 512 is relatively small, which is beneficial to shortening the overall length of the first pipeline 610 and the second pipeline 620, and thereby shortening the flow path of the functional liquid in the functional liquid tank 500 in the process of flowing to the infusion path 300, so that the functional liquid in the functional liquid tank 500 can flow to the infusion path 300 more quickly.

[0086] like Figure 8-Figure 9 As shown, in the length direction of the oral irrigator 1, the second interface 820 and the fourth interface 512 are located on the same side of the second pump body 700. That is to say, the first pipeline 610 and the second pipeline 620 are located on the same side of the second pump body 700, and the first pipeline 610 and the second pipeline 620 can be arranged side by side. In the length direction of the oral irrigator 1, the overall size of the first pipeline 610, the second pipeline 620 and the second pump body 700 is smaller, which reduces the size occupied by the first pipeline 610, the second pipeline 620 and the second pump body 700 in the length direction of the oral irrigator 1, which is conducive to improving the space utilization rate in the oral irrigator 1.

[0087] like Figure 1 and Figure 2 As shown, the above-mentioned water flosser 1 also includes a body 900, a water tank 200 and a nozzle 100 are arranged on the body 900, a first side 901 of the body 900 is provided with a button area 903, the liquid inlet of the first pump body 400 is close to the second side 902 of the body 900, and the first side 901 and the second side 902 are adjacently arranged in the circumferential direction of the water flosser 1, wherein the fourth interface 512 extends toward the second side 902.

[0088] Specifically, the first hard tube 800 can be connected to the liquid inlet of the first pump body 400, and the first side surface 901 and the second side surface 902 are arranged at intervals along the circumference of the fuselage 900. Since the key area 903 and the liquid inlet of the first pump body 400 are arranged in a spatially staggered manner, the leakage of liquid at the liquid inlet of the first pump body 400 to the key area 903 can be reduced, thereby preventing the user from being electrocuted when pressing the key area 903, thereby improving the safety of use.

[0089] Since the fourth interface 512 and the liquid inlet of the first pump body 400 are both close to the second side 902 of the body 900, the distance between the fourth interface 512 and the liquid inlet of the first pump body 400 is closer, which is beneficial to shortening the pipe length between the fourth interface 512 and the second interface 820, thereby shortening the flow path of the functional liquid in the functional liquid tank 500 to the infusion path 300, so that the functional liquid in the functional liquid tank 500 can flow to the infusion path 300 more quickly.
