[0060] 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.

[0061] The water tank 200 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0062] like Figure 1 and Figure 2 As shown, the water tank 200 of the embodiment of the present application includes a tank body and a water drawing pipe 500 .

[0063] The water tank 200 is provided with a water storage space 208 and a first opening 205. The water storage space 208 is connected to the first opening 205. The water storage space 208 is used to store liquid for cleaning the oral cavity, such as clean water or mouthwash, etc. The user can replenish the liquid for cleaning the oral cavity to the water storage space 208 through the first opening 205, and connect to the body 100 of the water flosser 1 through the first opening 205.

[0064] The water-drawing pipe 500 is disposed in the water storage space 208, one end of the water-drawing pipe 500 is fixedly connected to the box body and communicated with the first opening 205, and the lowest point of the other end of the water-drawing pipe 500 is closer to the bottom wall of the water storage space 208 relative to the lowest point of the first opening 205, wherein the other end of the water-drawing pipe 500 can face the bottom wall of the water storage space 208.

[0065] By providing a water drawing pipe 500, when the body 100 is connected to the water tank 200, the liquid in the water storage space 208 can be pumped out as much as possible to reduce the amount of liquid remaining in the water tank 200, thereby improving the utilization rate of the liquid and eliminating the step of pouring out the liquid in the water tank 200 after using the oral irrigator 1, making it more convenient to use. In addition, it is not easy for bacteria to grow in the water tank 200, and the cleaning effect on the oral cavity is better.

[0066] In addition, the water flosser of the prior art has a water pumping pipe on the body, and the water pumping pipe is inserted into the water tank. When the body and the water tank are separated, the water pumping pipe of the body will be exposed to the air, which is easy to be bumped, and the probability of being contaminated with dust and bacteria is high. When the body and the water tank are combined again, bacteria and dust can be brought into the water tank, causing the liquid for cleaning the oral cavity to breed bacteria, affecting oral health. The embodiment of the present application integrates the water pumping pipe 500 into the water tank 200, and the water pumping pipe 500 will not be exposed to the air, and the water pumping pipe 500 is not easy to contact with external objects, and the probability of being contaminated with dust and bacteria is low, and the liquid for cleaning the oral cavity will not breed bacteria, and the cleaning effect on the oral cavity is better.

[0067] Furthermore, since the water tank 200 is provided with a water drawing pipe 500, and one end of the water drawing pipe 500 connected to the first opening 205 is fixed to the tank body, after the water tank 200 is moved and transported, the liquid in the water tank 200 can still flow to the first opening 205 through the water drawing pipe 500. Therefore, regardless of whether the fuselage 100 has the water drawing pipe 500, it can be used in conjunction with the water tank 200, which is convenient to use and has a wide range of applications.

[0068] Specifically, the first opening 205 is arranged on the side wall and / or top wall of the box body, so that the first opening 205 has a certain distance from the bottom wall of the water storage space 208 in the length direction of the water flosser 1, which is convenient for processing and ensures the structural strength of the water tank 200, and the water tank 200 is connected to the bottom or side of the body 100, and the connection is more convenient.

[0069] like Fig. 9 and Fig.11As shown, the water tank 200 further includes a valve body 220, which is connected to the tank body and can be switched between an open state and a closed state. When the valve body 220 is in the open state, the water storage space 208 is connected to the external space of the water tank through the first opening 205; when the valve body 220 is in the closed state, the connection between the water storage space 208 and the external space of the water tank 200 is disconnected.

[0070] By providing the valve body 220 , the liquid in the water tank 200 will not accidentally leak from the first opening 205 , which facilitates the separate carrying and storage of the water tank 200 .

[0071] Among them, the water tank 200 can be provided with a water inlet 209, and the water tank 200 can inject water into the water storage space 208 through the water inlet 209. When the water tank 200 is replenished with liquid, the opening direction of the water inlet 209 is upward, and the water inlet 209 is located above the first opening 205 and the water storage space 208.

[0072] like Figure 3 , Figure 9-11 As shown, the outer surface of the box body is provided with a sealing protrusion 203, the sealing protrusion 203 surrounds the first opening 205, and the outer peripheral surface of the valve body 220 is provided with a first sealing rib 223, and the first sealing rib 223 cooperates with the inner peripheral surface of the sealing protrusion 203. When the valve body 220 moves relative to the first opening 205, the first sealing rib 223 and the inner peripheral surface of the sealing protrusion 203 are always sealed and matched.

[0073] By setting the first sealing rib 223, the gap between the inner circumference of the sealing protrusion 203 and the outer circumference of the valve body 220 can be filled, thereby ensuring that the liquid in the water storage space 208 will not leak from between the inner circumference of the sealing protrusion 203 and the outer circumference of the valve body 220.

[0074] like Figure 3 As shown, the oral irrigator 1 further includes a body 100, which is detachably connected to a water tank 200 and is provided with a second opening 105. When the water tank 200 is connected to the body 100, the valve body 220 is in an open state, and the first opening 205 is communicated with the second opening 105. A second sealing rib 229 is provided at one end of the valve body 220 facing away from the water storage space 2085, and the second sealing rib 229 is located between the sealing protrusion 203 and the body 100.

[0075] By setting the second sealing rib 229, the gap between the end face of the valve body 220 and the fuselage 100 can be filled, thereby ensuring that the liquid in the water storage space 208 will not leak from between the end face of the valve body 220 and the fuselage 100, and the first sealing rib 223 and the second sealing rib 229 form a double seal, which further improves the sealing effect and reduces the risk of liquid leakage.

[0076] like Fig. 9 and Fig.11 As shown, the valve body 220 includes a valve core 221 and a valve plate 222. The valve core 221 is slidably disposed in the first opening 205, and the valve plate 222 is connected to an end of the valve core 221 facing away from the body 100, and the valve plate 222 is located in the water storage space 208.

[0077] When the valve body 220 is in an open state, the water storage space 208 is connected to the first opening 205 ; when the valve body 220 is in a closed state, the valve plate 222 closes the first opening 205 and disconnects the first opening 205 from the water storage space 208 .

[0078] Since the valve plate 222 is located inside the water tank 200, the valve plate 222 will not collide with external objects, reducing the probability of damage to the valve plate 222. In addition, the stop between the valve plate 222 and the inner wall of the water tank 200 can limit the relative position between the water tank 200 and the valve body 220, preventing the valve body 220 from moving excessively outward and detaching from the water tank 200.

[0079] Specifically, when the water tank 200 is connected to the fuselage 100, the supporting member 106 abuts against the end of the valve core 221 facing the fuselage 100, thereby driving the valve core 221 to move away from the fuselage 100; when the water tank 200 is separated from the fuselage 100, the supporting member 106 is separated from the end of the valve core 221 facing the fuselage 100, thereby the valve core 221 is reset and moves toward the direction close to the fuselage 100.

[0080] By setting the valve core 221, when the body 100 and the water tank 200 are connected, the valve core 221 can contact the abutment 106 to achieve the purpose of driving the valve plate 222 to move, thereby achieving communication between the water storage space 208 and the first opening 205. The structure is simple and easy to implement.

[0081] like Figure 9-11 , Fig.13 As shown, the valve core 221 includes a valve column 224, a positioning portion 225 and a plurality of connecting ribs 226. The valve column 224 is slidably disposed at the first opening 205, and the valve plate 222 is connected to one end of the valve column 224 facing away from the body 100. The positioning portion 225 surrounds the valve column 224, and the positioning portion 225 is used to seal the first opening 205. One end of the connecting rib 226 is connected to the positioning portion 225 and the other end is connected to the valve column 224. When the valve body 220 is in an open state, the connecting rib 226 undergoes elastic deformation, so that the connecting rib 226 has a tendency to reset the valve body 220 to a closed state.

[0082] Specifically, when the water tank 200 is connected to the body 100, the abutting member 106 abuts against the end of the valve column 224 facing the body 100, thereby driving the valve core 221 to move in a direction away from the body 100. When the body 100 and the water tank 200 are connected, the positioning portion 225 is located between the body 100 and the water tank 200, and can seal the gap between the body 100 and the water tank 200, and when the valve column 224 moves relative to the first opening 205 in the axial direction of the first opening 205, the relative position of the positioning portion 225 and the first opening 205 in the axial direction of the first opening 205 remains unchanged.

[0083] In addition, the connecting rib 226 is elastic and can be made of rubber or silicone material. When the valve column 224 moves relative to the first opening 205 in the axial direction of the first opening 205, the valve column 224 and the positioning portion 225 also move relative to each other in the axial direction of the first opening 205. Therefore, the connecting rib 226 will undergo elastic deformation. Therefore, when the fuselage 100 and the water tank 200 are separated, the supporting member 106 is separated from the valve column 224, and the elastic force of the connecting rib 226 drives the valve column 224 to move toward the fuselage 100, thereby realizing the reset of the connecting rib 226.

[0084] like Figure 9-11 As shown, the valve body 220 further includes an elastic member 227, one end of the elastic member 227 is connected to the valve body 220, and the other end of the elastic member 227 is connected to the water tank 200 and / or the water drawing pipe 500; wherein, when the valve body 220 is in an open state, the elastic member 227 undergoes elastic deformation so that the elastic member 227 has a tendency to reset the valve body 220 to a closed state.

[0085] When the body 100 and the water tank 200 are connected, the valve plate 222 moves in the axial direction of the first opening 205 in the direction away from the first opening 205, that is, the valve plate 222 moves in the axial direction of the first opening 205 relative to the water tank 200 and the water drawing pipe 500, so the elastic member 227 will undergo elastic deformation. Therefore, when the body 100 and the water tank 200 are separated, the supporting member 106 separates from the valve core 221, and the elastic force of the elastic member 227 drives the valve plate 222 to move in the axial direction of the first opening 205 in the direction close to the first opening 205 until the valve plate 220 stops at the inner wall of the water tank 200, thereby disconnecting the first opening 205 from the water storage space 208.

[0086] When the other end of the elastic member 227 is connected to the water-drawing pipe 500, the water-drawing pipe 500 is constructed as a hard pipe, wherein the water-drawing pipe 500 can be made of hard plastic. Since the elastic member 227 is compressed when the water tank 200 and the fuselage 100 are connected, the elastic force of the elastic member 227 is applied to the water-drawing pipe 500. Therefore, by constructing the water-drawing pipe 500 as a hard pipe, the water-drawing pipe 500 is not easily deformed when subjected to force, and can reliably support the elastic member 227, so that the elastic member 227 is fully compressed and has sufficient elastic force, so as to facilitate driving the valve plate 222 to return to its original position when the water tank 200 and the fuselage 100 are separated, and disconnecting the first opening 205 from the water storage space 208.

[0087] like Fig. 9 and Fig.12 As shown, the water drawing pipe 500 is provided with a first receiving groove 510, and the elastic member 227 is inserted into the first receiving groove 510, and the elastic member 227 is provided between the valve plate 222 and the bottom wall of the first receiving groove 510. In this way, the first receiving groove 510 can limit the movement range of the elastic member 227 to prevent the elastic member 227 from being separated from the water drawing pipe 500, and can also reduce the volume of the elastic member 227 and the water drawing pipe 500 as a whole to prevent excessive occupation of the space in the water storage space 208, so that the water storage space 208 can accommodate more liquid.

[0088] like Fig. 9 and Fig.12 As shown, a positioning column 511 is provided on the bottom wall of the first receiving groove 510, and one end of the elastic member 227 is sleeved on the positioning column 511. The cross-sectional area of ​​the valve plate 222 gradually decreases in the direction away from the body 100, and the other end of the elastic member 227 is sleeved on the end of the valve plate 222 facing away from the body 100. The elastic member 227 can be a spring, that is, one end of the spring is sleeved on the positioning column 511, and the other end of the spring is sleeved on the end of the valve plate 222 facing the elastic member 227.

[0089] In this way, the elastic member 227 is limited by the positioning column 511 and the valve plate 222 to prevent the elastic member 227 from deflecting, thereby ensuring that the elastic member 227 can be used repeatedly, and the elastic force of the elastic member 227 can be effectively applied to the valve plate 222, so that the valve plate 222 can be reset faster. After the water tank 200 and the body 100 are separated, the valve core 221 can quickly disconnect the connection between the first opening 205 and the water storage space 208, thereby reducing the probability of leakage.

[0090] like Figure 2As shown, when the water tank 200 is connected to the body 100, the valve plate 222 is spaced apart from the bottom wall of the first receiving groove 510. In this way, when the water tank 200 is connected to the body 100, the water storage space 208 is connected to the first opening 205 through the gap between the valve plate 222 and the bottom wall of the first receiving groove 510, which can prevent the valve plate 222 from separating the water storage space 208 from the first opening 205, ensuring that the liquid in the water storage space 208 can flow into the second opening 105 through the first opening 205 and be sprayed out from the nozzle 300, so that the water flosser 1 can normally realize the function of spraying water to clean the oral cavity.

[0091] like Figure 9-11 As shown, the valve body 220 also includes a connecting pipe 600, the outer peripheral surface of the connecting pipe 600 is connected to the inner peripheral surface of the first accommodating groove 510, the valve core 221 is slidably disposed on the connecting pipe 600, and the cross-sectional area of ​​the valve plate 222 is larger than the cross-sectional area of ​​the connecting pipe 600; wherein, when the valve body 220 is in an open state, the valve plate 222 is separated from the connecting pipe 600, and the connecting pipe 600 is connected to the water storage space; when the valve body 220 is in a closed state, the valve plate 222 closes the end of the connecting pipe 600 facing the water storage space 208, disconnects the water storage space 208 and the connecting pipe 600, so as to disconnect the connection between the first opening 205 and the water storage space 208.

[0092] By separating the connecting tube 600 and the valve plate 222, the connection between the water storage space 208 and the first opening 205 can be achieved. By contacting the connecting tube 600 and the valve plate 222, the connection between the water storage space 208 and the first opening 205 can be disconnected. The moving stroke of the valve plate 222 is shorter, and the connection and disconnection between the water storage space 208 and the first opening 205 can be achieved more quickly.

[0093] Furthermore, the outer circumference of the connecting pipe 600 is provided with positioning teeth 610, and the first receiving groove 510 is provided with positioning holes 512, and the positioning teeth 610 are inserted into the positioning holes 512. In this way, the positioning and connection between the connecting pipe 600 and the water drawing pipe 500 can be achieved, and relative displacement between the connecting pipe 600 and the water drawing pipe 500 can be avoided.

[0094] Furthermore, one of the connecting pipe 600 and the water tank 200 is provided with a positioning block 230 and the other is provided with a positioning notch 640 , and the positioning block 230 is inserted into the positioning notch 640 .

[0095] In this way, the relative positions of the connecting pipe 600 and the water tank 200 in the circumferential direction of the connecting pipe 600 are stable, thereby preventing the connecting pipe 600 from rotating relative to the water tank 200. Since the relative positions of the water drawing pipe 500 and the connecting pipe 600 are stable in the circumferential direction of the connecting pipe 600, the relative positions of the water drawing pipe 500 and the water tank 200 in the circumferential direction of the connecting pipe 600 are stable, thereby ensuring that the end of the water drawing pipe 500 away from the connecting pipe 600 is directed toward the bottom wall of the water storage space 208, thereby allowing more liquid in the water storage space 208 to flow out, thereby reducing residual liquid in the water storage space 208.

[0096] Specifically, there are a plurality of positioning teeth 610 and a plurality of positioning holes 512, and the plurality of positioning teeth 610 are inserted into the plurality of positioning holes 512 one by one, and at least one of the plurality of positioning teeth 610 exceeds the outer circumference of the water drawing pipe 500 and stops at the inner surface of the water tank 200. The outer circumference of the connecting pipe 600 is further provided with a first outer ring 620, and the first outer ring 620 stops at the outer surface of the water tank 200.

[0097] In this way, the positioning teeth 610 and the first outer ring 620 can be limited from the inner and outer sides of the water tank 200 and the inner wall of the water tank 200, thereby limiting the relative position of the connecting pipe 600 and the water tank 200 in its axial direction, avoiding the connecting pipe 600 from being excessively inserted into the water storage space 208 and affecting the position of the water drawing pipe 500, ensuring that the liquid in the water storage space 208 can flow to the second opening 105 through the water drawing pipe 500, and preventing the connecting pipe 600 from excessively extending out of the water tank 200, thereby avoiding interference between the connecting pipe 600 and the fuselage 100, and ensuring convenient connection between the water tank 200 and the fuselage 100.

[0098] like Figure 8 , Fig. 9 as well as Fig.14 As shown, the outer surface of the water tank 200 is provided with a groove 204, the first outer ring 620 is provided in the groove 204, and the first opening 205 is provided at the bottom of the groove 204. The first outer ring 620 and the outer surface of the water tank 200 can be flush, or the first outer ring 620 does not exceed the outer surface of the water tank 200.

[0099] In this way, the first outer ring 620 will not protrude from the outer surface of the water tank 200 , and there will be no interference between the first outer ring 620 and the fuselage 100 , thereby ensuring that the connection between the water tank 200 and the fuselage 100 is convenient.

[0100] like Fig. 9As shown, the outer circumference of the connecting pipe 600 is further provided with a second outer ring 630, and the inner circumference of the water drawing pipe 500 is provided with an inner ring 513, and the inner ring 513 is provided between the second outer ring 630 and the positioning teeth 610. In this way, in the axial direction of the connecting pipe 600, the inner ring 513 is located between the second outer ring 630 and the positioning teeth 610, which can locate the relative position between the water drawing pipe 500 and the connecting pipe 600, and ensure that the liquid in the water storage space 208 can flow to the second opening 105 through the water drawing pipe 500.

[0101] like Fig. 9 and Fig.11 As shown, the outer circumferential surface of the valve core 221 is provided with a plurality of sliding ribs 228 , and the plurality of sliding ribs 228 are arranged at intervals along the circumference of the valve core 221 , and each sliding rib 228 extends along the axial direction of the valve core 221 , and the sliding rib 228 slides with the inner circumferential surface of the connecting pipe 600 .

[0102] In this way, on the one hand, the relative position between the valve core 221 and the connecting tube 600 in the radial direction of the connecting tube 600 can be limited by the sliding rib 228, thereby avoiding relative shaking of the valve core 221 and the connecting tube 600. On the other hand, the contact area between the valve core 221 and the connecting tube 600 is small, and the relative sliding between the valve core 221 and the connecting tube 600 is more convenient, thereby improving the smoothness of the movement of the valve core 221 in its axial direction.

[0103] like Figure 1 and Figure 2 As shown, the above-mentioned water flosser 1 includes a body 100 and a pump body 400. The body 100 is provided with a second opening 105, the water tank 200 is detachably connected to the body 100, the pump body 400 is arranged in the body 100 and communicated with the second opening 105, and the pump body 400 is used to extract the liquid in the water storage space 208, and the liquid is sprayed out from the nozzle 300.

[0104] The water tank 200 can be replenished with liquid when the body 100 is connected to the water tank 200, and can also be replenished with liquid when the body 100 is separated from the water tank 200. The water tank 200 has more diverse and flexible ways of replenishing liquid, and the body 100 and the water tank 200 are placed separately for easy carrying.

[0105] When the body 100 is connected to the water tank 200, since the valve body 220 is open, the liquid in the water tank 200 flows through the first opening 205 and the second opening 105 to the nozzle 300, and the water flosser 1 can normally realize the function of spraying water to clean the oral cavity; when the body 100 and the water tank 200 are separated, since the valve body 220 is closed, the liquid in the water tank 200 will not leak through the first opening 205, the sealing effect of the water tank 200 is good, the setting flexibility of the first opening 205 is high, and the water tank 200 is smaller in size than the water flosser 1, which is convenient for users to hold, and it is more convenient to add liquid to the water tank 200. The separation of the water tank 200 and the body 100 is more convenient to place and carry. Among them, when the water tank 200 is added with liquid, the opening direction of the water inlet 209 faces upward, and the water inlet 209 is located above the first opening 205 and the water storage space 208.

[0106] like Figure 1 and Figure 2 As shown, the end of the body 100 is connected to the water tank 200, and the body 100 and the water tank 200 can be arranged along the length direction of the water flosser 1, or the side of the body 100 is connected to the water tank 200, and the body 100 and the water tank 200 are arranged along the radial direction of the water flosser 1. In this way, the arrangement of the water flosser 1 is more diverse, and the arrangement flexibility of the water flosser 1 is increased to be suitable for different usage scenarios.

[0107] like Figure 2-Figure 5 , Figure 7 As shown, a resisting member 106 is disposed at the second opening 105 . When the water tank 200 is connected to the body 100 , the resisting member 106 abuts against the valve body 220 to open the valve body 220 .

[0108] In this way, the switching state of the valve body 220 is directly linked to the separation and connection between the water tank 200 and the body 100, which is beneficial to ensure the sealing effect of the valve body 220 on the first opening 205 when the water tank 200 and the body 100 are separated, and to ensure that the first opening 205 is open when the water tank 200 and the body 100 are connected, so that the first opening 205 is connected with the second opening 105, thereby facilitating the normal operation of the water flosser 1 and the independent operation of the water tank 200 to replenish liquid.

[0109] When the end of the fuselage 100 is connected to the water tank 200, the water tank 200 is located below the fuselage 100, and the water inlet 203 is provided on the top wall of the water tank 200. Under the action of the gravity of the fuselage 100, the abutment 106 keeps the valve body 220 open;

[0110] When the side of the body 100 is connected to the water tank 200, a connection structure is provided between the body 100 and the water tank 200, and the connection structure is used to fix the relative positions of the body 100 and the water tank 200. The water inlet 203 is provided on the side wall of the water tank 200. Under the connection force of the connection structure, the abutment 106 keeps the valve body 220 open. The connection structure may be a buckle, Velcro, a restraint belt, a magnetic structure, etc.

[0111] In this way, when the water tank 200 and the body 100 are connected, the supporting member 106 can stably open the valve body 220 to prevent the valve body 220 from accidentally resetting and disconnecting the connection between the water storage space 208 and the second opening 105, thereby maintaining an effective connection between the water storage space 208 and the second opening 105.

[0112] like Figure 5 and Figure 7 As shown, when the pump body 400 is connected to the water drawing assembly 410, the water drawing assembly 410 is provided with a resisting member 106, and the resisting member 106 passes through the second opening 105, or the body 100 is provided with a resisting member 106. In this way, the resisting member 106 has more structural modes and is more flexible.

[0113] like Figure 5 and Figure 7 As shown, the pump body 400 is connected to a water drawing assembly 410, and the water drawing assembly 410 includes an interface 411, a hose 412, and a filter 413. The interface 411 is connected to the inner wall of the body 100 and communicates with the second opening 105. The hose 412 is connected to the interface 411 and the pump body 400 respectively. The filter 413 is provided at the interface 411 and is located between the hose 412 and the second opening 105, and the filter 413 is used to filter the liquid flowing from the second opening 105 to the hose 412.

[0114] In this way, the hose 412 can connect the interface part 411 and the pump body 400, and the hose 412 can change its shape according to the internal arrangement of the pump body 100, so as to facilitate the connection between the interface part 411 and the pump body 400, thereby improving the layout flexibility of the oral irrigator 1.

[0115] By providing the interface member 411, the hardness of the interface member 411 can be greater than the hardness of the hose 412, and the interface member 411 can change the flow direction of the liquid, ensuring that the liquid in the second opening 105 flows more smoothly to the hose 412. In addition, the interface member 411 and the body 100 can be fixedly connected, for example, the interface member 411 and the body 100 can be positioned and connected by a threaded fastener to avoid relative displacement between the interface member 411 and the body 100, so that the relative positions of the two ends of the hose 412 and the body 100 are fixed, and the hose 412 is prevented from shaking in the body 100.

[0116] In addition, before the liquid flows into the hose 412, it will flow through the filter 413, and the filter 413 removes impurities in the liquid, thereby improving the cleanliness of the liquid in the hose 412, and then improving the cleanliness of the liquid sprayed from the nozzle 300. The water flosser 1 is safer for cleaning teeth and is beneficial to improving the oral health of the user.

[0117] like Figure 3 , Figure 5 and Figure 6 As shown, the water-drawing assembly 410 further includes a pressing member 414, the interface member 411 is provided with a second receiving groove 420, the filter member 413 is provided in the second receiving groove 420, the pressing member 414 is inserted in the second receiving groove 420 and stops at the inner wall of the fuselage 100, and the filter member 413 is clamped between the pressing member 414 and the bottom wall of the second receiving groove 420.

[0118] That is to say, the filter element 413 is clamped between the interface element 411 and the clamping element 414 in the axial direction of the second accommodating groove 420, so as to prevent the filter element 413 from being displaced relative to the interface element 411, thereby ensuring that the liquid flowing into the hose 412 will pass through the filter element 413, thereby further improving the cleanliness of the liquid in the hose 412.

[0119] Furthermore, since the interface member 411 is provided with a second accommodating groove 420, the second accommodating groove 420 is used to accommodate the filter member 413 and the clamping member 414, and can fix the relative position of the clamping member 414 and the interface member 411, thereby maintaining the relative position stability among the filter member 413, the interface member 411 and the clamping member 414.

[0120] like Figure 3 , Figure 5 and Figure 6 As shown, the pressing member 414 is elastically deformable and can be made of soft rubber materials such as rubber, silicone, etc. The pressing member 414 includes a first hole section 4141 and a second hole section 4142 .

[0121] The filter element 413 is clamped between the first hole section 4141 and the bottom wall of the second accommodating groove 420, the second hole section 4142 is connected to the end of the first hole section 4141 facing away from the filter element 413, and the inner wall of the fuselage 100 is provided with a clamping protrusion 104, which is inserted into the second hole section 4142 and stops at the first hole section 4141.

[0122] That is to say, the first hole section 4141 can be pressed by the end of the clamping protrusion 104 and pressed against the filter element 413. The first hole section 4141 can be elastically deformed and filled between the end of the clamping protrusion 104 and the bottom wall of the second receiving groove 420. On the one hand, it can prevent the filter element 413 from moving in the second receiving groove 420 to ensure the filtering effect of the filter element 413. On the other hand, it prevents liquid from flowing out from between the end of the clamping protrusion 104 and the bottom wall of the second receiving groove 420, thereby reducing the probability of liquid leaking into the fuselage 100.

[0123] The second hole section 4142 can be compressed between the outer circumference of the clamping protrusion 104 and the inner circumference of the second receiving groove 420. The second hole section 4142 can be elastically deformed to fill the space between the outer circumference of the clamping protrusion 104 and the inner circumference of the second receiving groove 420, thereby preventing liquid from leaking from between the outer circumference of the clamping protrusion 104 and the inner circumference of the second receiving groove into the fuselage 100, further reducing the probability of liquid leakage into the fuselage 100, ensuring that the liquid in the second receiving groove 420 flows to the hose 412 through the filter element 413, thereby reducing the probability of short circuit of electrical components in the fuselage 100.

[0124] like Figure 3 , Figure 5 and Figure 6 As shown, the inner wall of the fuselage 100 is provided with a positioning protrusion 103, and the positioning protrusion 103 surrounds the interface member 411. In this way, the positioning protrusion 103 can limit the position of the interface member 411 in its radial direction to ensure that the interface member 411 is within the surrounding range of the positioning protrusion 103, thereby avoiding relative displacement between the fuselage 100 and the interface member 411.

[0125] like Figure 4 and Figure 8 As shown, the above-mentioned fuselage 100 is provided with a sealing protrusion 203, the sealing protrusion 203 surrounds the second opening 105, the water tank 200 is provided with a sealing groove 107, the bottom wall of the sealing groove 107 is provided with a first opening 205, and the sealing protrusion 203 is inserted into the sealing groove 107; or the fuselage 100 is provided with a sealing groove 107, the bottom wall of the sealing groove 107 is provided with the second opening 105, the water tank 200 is provided with a sealing protrusion 203, the bottom wall of the sealing protrusion 203 surrounds the first opening 205, and the sealing protrusion 203 is inserted into the sealing groove 107.

[0126] When the side of the body 100 is connected to the water tank 200, the sealing protrusion 203 and the sealing groove 107 cooperate to provide support in the length direction of the oral irrigator 1, thereby preventing the body 100 and the water tank 200 from being misaligned in the length direction of the oral irrigator 1 and reducing the probability of the body 100 and the water tank 200 being separated.

[0127] When the end of the body 100 is connected to the water tank 200, the sealing protrusion 203 and the sealing groove 107 cooperate to limit the radial direction of the oral irrigator 1, thereby preventing the body 100 and the water tank 200 from being misaligned in the radial direction of the oral irrigator 1 and reducing the probability of separation of the body 100 and the water tank 200.

[0128] like Figure 2 , Figure 4 , Figure 8 , Fig.14 As shown, the side of the fuselage 100 is connected to the water tank 200 , the second opening 105 is provided at the bottom end of the fuselage 100 , and the first opening 205 is provided at the bottom end of the water tank 200 .

[0129] In this way, the distance between the first opening 205 and the bottom wall of the water tank 200 is closer, the length of the water drawing pipe 500 can be shortened, less liquid residue is left in the water tank 200, and the distance between the second opening 105 and the first opening 205 is closer. Without the need to set up an additional connecting structure, the connection between the second opening 105 and the first opening 205 can be achieved, and the structure of the water flosser 1 is simpler.
