[0069] 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.

[0070] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0072] 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.

[0073] The oral irrigator 1 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0074] like Figure 1 and Figure 2 as well as Figure 11-Figure 18 As shown, the oral irrigator 1 of the embodiment of the present application includes a body 100 and a water tank 200 .

[0075] The top of the body 100 can be connected to the nozzle 300, and the water tank 200 is connected to the body 100. The water tank 200 defines a water storage space 208 or defines a water storage space 208 together with the body 100. The water storage space 208 is used to store liquid for cleaning the oral cavity, such as clean water or mouthwash. The pump body 400 is arranged in the body 100, and is used to pump the liquid in the water storage space 208 to the nozzle 300. A buffer pad can be arranged between the body 100 and the water tank 200, which can increase the friction between the body 100 and the water tank 200, maintain the relative position between the body 100 and the water tank 200, and reduce the collision noise between the body 100 and the water tank 200.

[0076] In addition, the water flosser 1 has a first direction (the direction indicated by arrow A in the accompanying drawings), which is vertically arranged to the length direction of the water flosser 1 (the direction indicated by arrow C in the accompanying drawings), and at least a portion of the water tank 200 and the body 100 are arranged along the first direction to increase the center of gravity of the liquid in the water tank 200.

[0077] Since the height of the nozzle 300 is usually higher than the water tank 200, by arranging at least a portion of the water tank 200 and the body 100 along the first direction, the center of gravity of the liquid in the water tank 200 is increased, and the center of gravity of the liquid in the water tank 200 is closer to the nozzle 300 in the length direction of the oral irrigator 1. The energy required to pump the liquid in the water tank 200 to the nozzle 300 and then spray it out is relatively small, which can save energy and improve the endurance of the oral irrigator 1. In addition, after the center of gravity of the water tank 200 is increased, the distance between the center of gravity of the water tank 200 and the center of gravity of the body 100 in the length direction of the oral irrigator 1 is shortened, which is beneficial to the placement stability of the oral irrigator 1 and avoids shaking when the oral irrigator 1 is placed.

[0078] like Figure 1 As shown, the arrangement of the above-mentioned water flosser 1 is at least one of the following:

[0079] The first type is that the water tank 200 and the body 100 are arranged along the first direction, that is, the water tank 200 as a whole is located at the side of the body 100 in the first direction, so that the water tank 200 and the body 100 as a whole have smaller dimensions in the length direction of the oral irrigator 1;

[0080] The second type is that a part of the water tank 200 and the body 100 are arranged along the length direction of the oral irrigator 1, and another part of the water tank 200 and the body 100 are arranged along the first direction. In this way, the water tank 200 defines the position of the body 100 in the length direction and the first direction of the oral irrigator 1, and the water tank 200 and the body 100 can support each other in the length direction of the oral irrigator 1, and the water tank 200 and the body 100 are not easy to separate;

[0081] The third type is that a part of the body 100 and the water tank 200 are arranged along the length of the oral irrigator 1, and the other part of the body 100 and the water tank 200 are arranged along the first direction. In this way, the body 100 limits the position of the water tank 200 in the length direction of the oral irrigator 1 and the first direction, and the water tank 200 and the body 100 can support each other in the length direction of the oral irrigator 1, and the water tank 200 and the body 100 are not easy to separate.

[0082] Furthermore, the water tank 200 surrounds the body 100, so that the water tank 200 is on the outside and the body 100 is on the inside, which not only facilitates the arrangement of components in the body 100, but also increases the volume of the water tank 200, and the endurance of the oral irrigator 1 is stronger.

[0083] Alternatively, the body 100 surrounds the water tank 200, so that the water tank 200 is on the inside and the body 100 is on the outside. The operating module 130 and the display module 140 are generally arranged on the body 100. The outer peripheral surface of the body 100 is convenient for users to contact and operate the operating module 130 and the display module 140. In addition, the operating module 130 and the display module 140 are arranged in more positions in the length direction of the water flosser 1, thereby improving the structural flexibility of the water flosser 1.

[0084] like Figure 1 and Figure 2 As shown, the top of the water tank 200 can be flush with the top of the body 100, that is, the top surface of the water tank 200 and the top surface of the body 100 can be located in the same plane. In this way, there will be no steps between the top of the water tank 200 and the top of the body 100, thereby avoiding the accumulation of impurities between the top of the water tank 200 and the top of the body 100, thereby reducing the probability of bacteria breeding in the water flosser 1.

[0085] Since the top surface of the water tank 200 does not exceed the top surface of the body 200, when the nozzle 300 is extended into the oral cavity, the water tank 200 will not collide with the teeth; since the top surface of the body 200 does not exceed the top surface of the water tank 200, the water inlet 209 of the water tank 200 can be set at the top, and the water tank 200 does not need to be restricted by the body 200 when filling water, and filling water is more convenient. In addition, since the oral irrigator 1 is tilted when used, and since the nozzle 300 is on the side of the body 100, the flushed water flows downward after entering the oral cavity and flows to the top of the water tank 200. Then it will flow along the direction of gravity to the gap between the fuselage 100 and the water tank 200. Dirt and grime are easily hidden between the contact surfaces of the fuselage 100 and the water tank 200. In the case where connection ports (such as the first port 105 and the second port 205) are provided on the side of the fuselage 100 facing the water tank 200 and the side of the water tank 200 facing the fuselage 100, the above connection ports are also easily contaminated. Therefore, the top surface of the fuselage 200 does not exceed the top surface of the water tank 200 to prevent the formation of steps and reduce the probability of bacterial growth.

[0086] In addition, the bottom of the water tank 200 can be flush with the bottom of the body 100, and the distance between the center of gravity of the water tank 200 and the center of gravity of the body 100 in the length direction of the water flosser 1 is closer, which is beneficial to the placement stability of the water flosser 1, further avoiding the shaking of the water flosser 1 when it is placed, and the power required for pumping water is smaller, which is beneficial to energy saving and long battery life;

[0087] In some embodiments of the present application, the top of the water tank 200 and the top of the fuselage 100 are located in the same plane. In this case, the top of the water tank 200 and the top of the fuselage 100 can be set flush or inclined to avoid forming a step structure at the transition between the top of the water tank 200 and the top of the fuselage 100.

[0088] like Figure 1 and Figure 2 As shown, in the first direction, the side of the body 100 facing away from the water tank 200 is provided with an operating module 130 and a display module 140. The operating module 130 and the display module 140 may be connected to the circuit board 120.

[0089] That is to say, the display module 140 and the operation module 130 are located on the same side of the body 100. The display module 140 can be a display screen, and at least a portion of the display module 140 is exposed from the body 100, so that the user can view the content displayed by the display module 140. The operation module 130 can be a button, an operating lever, a sliding key, etc., and at least a portion of the operation module 130 is exposed from the body 100, so that the user can operate the operation module 130 to control the water flosser 1.

[0090] In addition, the operating module 130 and the water tank 200 are arranged on opposite sides of the body 100 in the first direction. When the user applies pressure to the operating module 130, the body 100 is forced to move toward the water tank 200, thereby preventing the body 100 and the water tank 200 from being misaligned in the second direction.

[0091] In addition, the operating module 130 is located above the display module 140. During the use of the oral irrigator 1, the user's fingers may always be placed on the operating module 130. When the liquid sprayed from the nozzle 300 flows downward, the fingers will prevent the liquid from continuing to flow downward, thereby reducing the probability of the display module 140 being covered with liquid. The user's observation of the display module 140 is always clear, and the experience is better.

[0092] The water tank 200 and the body 100 are arranged along the first direction, the cross-sectional area of ​​the water tank 200 is S1, the cross-sectional area of ​​the body 100 is S2, and the ratio of S1 to S2 is not less than 0.5 and not greater than 2. The ratio of S1 to S2 can be 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9 or 2.

[0093] When the ratio of S1 to S2 is less than 0.5, the cross-sectional area of ​​the water tank 200 is too small, resulting in too little liquid stored in the water tank 200. During the use of the oral irrigator 1, the liquid is easily exhausted and needs to be repeatedly refilled, resulting in a poor user experience. Alternatively, the cross-sectional area of ​​the body 100 is too large, resulting in the oral irrigator 1 being inconvenient to hold and being too heavy.

[0094] When the ratio of S1 to S2 is greater than 2, the cross-sectional area of ​​the water tank 200 is too large, which makes it difficult to hold the oral irrigator 1, and the internal space of the water tank 200 is too large. If less water is added, the space is wasted. If more water is added, the oral irrigator 1 is too heavy and more inconvenient to hold. Alternatively, the cross-sectional area of ​​the body 100 is too small, and the components in the body 100 are arranged too compactly, making heat transfer inconvenient, which easily leads to the accelerated aging of the components in the body 100.

[0095] When the ratio of S1 to S2 is not less than 0.5 and not greater than 2, the cross-sectional area of ​​the water tank 200 is relatively close to that of the body 100, and the cross-sectional area of ​​the water tank 200 is moderate to that of the body 100. On the one hand, the water tank 200 can store sufficient liquid for cleaning the oral cavity, and the components in the body 100 can be more dispersed to avoid heat accumulation and reduce the aging speed. On the other hand, the oral irrigator 1 is easy to hold and can be better optimized for use.

[0096] The water tank 200 and the body 100 are arranged along the first direction, the size of the water tank 200 in the first direction is L1, the cross-sectional area of ​​the body 100 is L2, and the ratio of L1 to L2 is not less than 0.5 and not greater than 2. The ratio of L1 to L2 can be 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9 or 2.

[0097] When the ratio of L1 to L2 is less than 0.5, the size of the water tank 200 in the first direction is too small, resulting in too little liquid stored in the water tank 200. During the use of the oral irrigator 1, the liquid is easily exhausted and needs to be repeatedly refilled, resulting in a poor user experience. Alternatively, the size of the body 100 in the first direction is too large, resulting in the oral irrigator 1 being inconvenient to hold and being too heavy.

[0098] When the ratio of S1 to S2 is greater than 2, the size of the water tank 200 in the first direction is too large, which makes it difficult to hold the oral irrigator 1, and the internal space of the water tank 200 is too large. If less water is filled, the space is wasted. If more water is filled, the oral irrigator 1 is too heavy and more inconvenient to hold. Alternatively, the size of the body 100 in the first direction is too small, and the components in the body 100 are arranged too compactly, which makes heat transfer inconvenient, and easily leads to the accelerated aging of the components in the body 100.

[0099] When the ratio of S1 to S2 is not less than 0.5 and not greater than 2, the size of the water tank 200 in the first direction is relatively close to the size of the body 100 in the first direction, and the size of the water tank 200 in the first direction is moderate to the size of the body 100 in the first direction. On the one hand, the water tank 200 can store sufficient liquid for cleaning the oral cavity, and the components in the body 100 can be more dispersed to avoid heat accumulation and reduce the aging speed. On the other hand, the water flosser 1 is easy to hold and can be better optimized for use.

[0100] The cross-sectional area of ​​the above-mentioned water flosser 1 is not greater than 35cm². The cross-sectional area of ​​the water flosser 1 may be not less than 5cm². That is to say, whether the side of the body 100 is connected to the water tank 200 or the end of the body 100 is connected to the water tank 200, the cross-sectional area of ​​the water flosser 1 will not be less than 35cm². For example, the cross-sectional area of ​​the water flosser 1 may be 5cm², 6cm², 7cm², 8cm², 9cm², 10cm², 11cm², 12cm², 13cm², 14cm², 15cm², 16cm², 17cm², 18cm², 19cm², 20cm², 21cm², 22cm², 23cm², 24cm², 25cm², 26cm², 27cm², 28cm², 29cm², 30cm², 31cm², 32cm², 33cm², 34cm², 35cm².

[0101] In this way, the cross-sectional area of ​​the water flosser 1 is smaller, which is convenient for the user to hold. The user can more easily adjust the posture of the water flosser 1 when the water flosser 1 cleans the oral cavity. The liquid in the water flosser 1 can be sprayed to various areas of the oral cavity to avoid cleaning dead corners in the oral cavity, achieve all-round cleaning of the oral cavity, and have a more thorough cleaning effect and a better user experience.

[0102] like Figure 1-Figure 2 As shown, the above-mentioned water flosser 1 also has a second direction (the direction indicated by arrow B in the attached figure), the first direction, the second direction and the length direction of the water flosser 1 are arranged vertically in pairs, the size of the water flosser 1 in the first direction is greater than the size of the water flosser 1 in the second direction, and the water flosser 1 can present an elliptical structure or an oblong structure, which conforms to the holding habit of human hands. In addition, there is a smooth transition between the water tank 200 and the fuselage 100. In this way, no step structure is formed between the water tank 200 and the fuselage 100. On the one hand, the grip feel of the water flosser 1 is optimized, so that the water flosser 1 fits the palm more closely and avoids the palm from being suspended in the air. On the other hand, the connection between the water tank 200 and the fuselage 100 is easy to clean, not easy to hide dirt and accumulate dust, which is conducive to the cleaning of the water flosser 1.

[0103] The water tank 200 and the body 100 are arranged along the first direction, and the cross-sectional area of ​​the water tank 200 remains unchanged. In this way, the gravity of the water tank 200 is uniform in the length direction of the water flosser 1, which avoids the situation that the upper weight of the water tank 200 is greater than the lower weight. The water flosser 1 is stable when placed, and the lower cross-sectional area of ​​the water tank 200 is prevented from being too large, resulting in poor holding comfort. In addition, since the lower part of the water tank 200 is closer to the wrist on the human hand, if the lower volume of the water tank 200 is larger, the rotation of the wrist may cause the water flosser to fail to clean various areas of the oral cavity.

[0104] The water tank 200 and the body 100 are arranged along the first direction, and the cross-sectional area of ​​the body 100 remains unchanged. In this way, the body 100 has uniform gravity in the length direction of the oral irrigator 1, which prevents the upper weight of the body 100 from being greater than the lower weight. The oral irrigator 1 is stable when placed, and the lower cross-sectional area of ​​the body 100 is prevented from being too large, resulting in poor grip comfort. In addition, since the lower part of the body 100 is closer to the wrist on the human hand, if the lower part of the body 100 is larger, the rotation of the wrist may prevent the oral irrigator from cleaning various areas of the oral cavity.

[0105] The water tank 200 and the body 100 are detachable, and the water tank 200 and the body 100 are separated along the first direction. Since the first direction is perpendicular to gravity, the water tank 200 and the body 100 will not be separated due to the influence of gravity, thereby avoiding the situation where the water flosser is accidentally separated and damaged, and the structure of the water flosser 1 is more reasonable.

[0106] like Figure 2 As shown, one of the fuselage 100 and the water tank 200 is provided with a raised portion 202 and the other is provided with a recessed portion 102, and the raised portion 202 is inserted into the recessed portion 102. The cross-sectional area of ​​the raised portion 202 gradually decreases toward the recessed portion 102, and the shape of the recessed portion 102 matches the shape of the raised portion 202, which can serve as an installation guide and facilitate rapid positioning and assembly.

[0107] The cooperation between the raised portion 202 and the recessed portion 102 facilitates the positioning between the body 100 and the water tank 200, shortens the installation time between the body 100 and the water tank 200, improves production efficiency, and facilitates assembly and provides a better user experience during use. In addition, the raised portion 202 and the recessed portion 102 can play a supporting role to prevent the body 100 and the water tank 200 from being misaligned in the length direction of the oral irrigator 1.

[0108] Among them, other connection structures can also be provided between the fuselage 100 and the water tank 200, such as a snap connection, a sliding connection, a Velcro connection, a screw connection, a magnetic connection, etc., so that the connection between the fuselage 100 and the water tank 200 is reliable.

[0109] Furthermore, there are multiple protrusions 202 and multiple recesses 102, and the multiple protrusions 202 correspond to the multiple recesses 102 one by one, and the multiple protrusions 202 are arranged at intervals along the length direction of the water flosser 1; the distance between the uppermost protrusion 202 and the top of the water tank 200 is smaller than the distance between the protrusion 202 and the middle of the water tank 200, and the distance between the lowermost protrusion 202 and the bottom of the water tank 200 is smaller than the distance between the protrusion 202 and the middle of the water tank 200.

[0110] In this way, the raised portion 202 at the uppermost part is closer to the top of the water tank 200, and the raised portion 202 at the lowermost part is closer to the bottom of the water tank 200. The connecting force between the water tank 200 and the fuselage 100 can act on the upper and lower ends of the water tank 200, thereby preventing the water tank 200 from rotating relative to the fuselage 100, and making the relative position between the water tank 200 and the fuselage 100 more stable.

[0111] Specifically, one of the protrusion 202 and the recess 102 is provided with a first magnetic member 101 and the other is provided with a second magnetic member 201, and the first magnetic member 101 and the second magnetic member 201 are magnetically matched. The gap between the first magnetic member 101 and the second magnetic member 201 may be no greater than 3 mm to increase the magnetic attraction between the first magnetic member 101 and the second magnetic member 201.

[0112] For example, the first magnetic component 101 can be a permanent magnet, such as a magnet. In this case, the second magnetic component 201 can also be a permanent magnet, such as a magnet, and the first magnetic component 101 and the second magnetic component 201 have opposite polarities. Of course, the second magnetic component 201 can also be a metal that can be magnetically attracted (such as iron) or other materials that can be magnetically attracted; the second magnetic component 201 can be a permanent magnet, such as a magnet. In this case, the first magnetic component 101 can also be a permanent magnet, such as a magnet, and the first magnetic component 101 and the second magnetic component 201 have opposite polarities. Of course, the first magnetic component 101 can also be a metal that can be magnetically attracted (such as iron) or other materials that can be magnetically attracted.

[0113] By setting the first magnetic component 101 and the second magnetic component 201, during the assembly of the water flosser 1, the magnetic force can guide the water tank 200 and the body 100, and the water tank 200 and the body 100 can be automatically positioned and connected without the need for manual alignment by the user, making the installation more convenient. In addition, the magnetic force between the first magnetic component 101 and the second magnetic component 201 can prevent the water tank 200 and the body 100 from separating, thereby playing a role in connecting and fixing.

[0114] When the water tank 200 is connected to the end of the fuselage 100, the sum of the gravity of the water tank 200 and the gravity of the liquid in the water storage space 208 is less than the magnetic attraction force, so that the water tank 200 remains connected to the fuselage 100, wherein the gravity of the water tank 200 refers to the gravity of the water tank 200 itself when there is no liquid in the water storage space 208202. After the first magnetic attraction member 101 and the second magnetic attraction member 201 are aligned, it can also ensure that the water tank 200 can be stably connected to the fuselage 100 regardless of whether there is water in the wheel water storage space 208, so as to avoid the separation of the water tank 200 and the fuselage 100, and the use is reliable.

[0115] When the water tank 200 is connected to the side of the body 100, the water tank 200 is connected to the body 100 at least by magnetic attraction, that is, the water tank 200 and the body 100 can be connected only by magnetic attraction, or the water tank 200 and the body 100 are not only connected by magnetic attraction, but there are other forces between the water tank 200 and the body 100 to maintain the relative position. Due to the existence of magnetic attraction, even if there are other forces, other forces can be reduced to a certain extent. The implementation methods of other forces are more flexible, and the structural methods of the water flosser 1 are more diverse, which is conducive to improving the applicability of the water flosser 1 and reducing costs.

[0116] Furthermore, the body 100 includes a pump body 400, and the arrangement of the water flosser 1 is at least one of the following:

[0117] First, at least part of the first magnetic member 101 and the motor 410 of the pump body 400 are arranged in a staggered manner in the length direction of the oral irrigator 1;

[0118] The second type is that at least part of the second magnetic element 201 and the motor 410 of the pump body 400 are arranged in a staggered manner in the length direction of the oral irrigator 1;

[0119] The third type is that on a plane perpendicular to the length direction of the oral irrigator 1, at least part of the orthographic projection of the first magnetic attraction member 101 is arranged in a staggered manner with the orthographic projection of the motor 410 of the pump body 400;

[0120] Fourthly, on a plane perpendicular to the length direction of the oral irrigator 1 , at least a portion of the orthographic projection of the second magnetic element 201 is staggered with the orthographic projection of the motor 410 of the pump body 400 .

[0121] In this way, the first magnetic component 101 and the second magnetic component 201 can be staggered with the motor 410, reducing the interference of the first magnetic component 101 and the second magnetic component 201 on the internal magnet of the motor 410, avoiding the occurrence of power decline of the motor 410, ensuring the normal use of the motor 410, and extending the service life of the motor 410.

[0122] like Figure 6-Figure 8 As shown, the fuselage 100 and the water tank 200 are detachably connected, the fuselage 100 is provided with a first interface 105, the water tank 200 is provided with a second interface 205, the first interface 105 is connected to the pump body 400 in the fuselage 100, and the second interface 205 is provided with a valve body 210; when the water tank 200 is connected to the fuselage 100, the valve body 210 is opened, and the first interface 105 and the second interface 205 are connected; when the water tank 200 is separated from the fuselage 100, the valve body 210 is closed, and the connection between the first interface 105 and the second interface 205 is disconnected.

[0123] 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.

[0124] When the body 100 is connected to the water tank 200, since the valve body 210 is open, the liquid in the water tank 200 flows to the nozzle 300 through the second interface 205 and the first interface 105, and the oral irrigator 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 210 is closed, the liquid in the water tank 200 will not leak through the second interface 205, the sealing effect of the water tank 200 is good, the setting flexibility of the second interface 205 is high, and the water tank 200 is smaller in size than the oral irrigator 1, which is convenient for users to hold, and it is more convenient to add liquid to the water tank 200. After the water tank 200 and the body 100 are separated, it is easier to place and carry. Among them, when adding liquid to the water tank 200, the opening direction of the water inlet 209 faces upward, and the water inlet 209 is located above the second interface 205 and the water storage space 208.

[0125] like Figure 6-Figure 8 As shown, further, a resisting member 106 is provided at the first interface 105, and when the water tank 200 is connected to the body 100, the resisting member 106 stops at the valve body 210 to open the valve body 210. In this way, the switch state of the valve body 210 is directly linked with the separation and connection between the water tank 200 and the body 100, which is conducive to ensuring the sealing effect of the valve body 210 on the second interface 205 when the water tank 200 and the body 100 are separated, and ensuring that the second interface 205 is open when the water tank 200 and the body 100 are connected, so that the second interface 205 is connected with the first interface 105, which is convenient for realizing the normal operation of the water flosser 1, and operating the water tank 200 alone to replenish liquid.

[0126] like Figure 2 As shown, specifically, the water tank 200 and the body 100 are arranged along the first direction, the first interface 105 is provided at the bottom of the peripheral side of the body 100, and the second interface 205 is provided at the bottom of the peripheral side of the water tank 200. In this way, the distance between the second interface 205 and the bottom wall of the water tank 200 is closer, the second interface 205 is connected to a water pumping pipe 207, the water pumping pipe 207 is located in the water storage space 208 and faces the bottom wall of the water storage space 208, the length of the water pumping pipe 207 can be shortened, less liquid remains in the water tank 200, and the distance between the first interface 105 and the second interface 205 is closer, and the communication between the first interface 105 and the second interface 205 can be achieved without additionally setting a communication structure, and the structure of the water flosser 1 is simpler.

[0127] like Figure 6-Figure 8 As shown, one of the body 100 and the water tank 200 is provided with a sealing protrusion 204 and the other is provided with a sealing groove 107 . When the water tank 200 is connected to the body 100 , the sealing protrusion 204 surrounds the first interface 105 and the second interface 205 .

[0128] For example, the fuselage 100 is provided with a sealing protrusion 204, the sealing protrusion 204 surrounds the first interface 105, the water tank 200 is provided with a sealing groove 107, the bottom wall of the sealing groove 107 is provided with a second interface 205, and the sealing protrusion 204 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 a first interface 105, the water tank 200 is provided with a sealing protrusion 204, the bottom wall of the sealing protrusion 204 surrounds the second interface 205, and the sealing protrusion 204 is inserted into the sealing groove 107.

[0129] When the side of the body 100 is connected to the water tank 200, the sealing protrusion 204 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;

[0130] When the end of the body 100 is connected to the water tank 200, the sealing protrusion 204 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.

[0131] like Figure 6-Figure 8 As shown, in the case where the outer surface of the water tank 200 is provided with a sealing protrusion 204, the sealing protrusion 204 surrounds the second interface 205. The outer circumference of the valve body 210 is provided with a first sealing rib 211, and the first sealing rib 211 cooperates with the inner circumference of the sealing protrusion 204. By providing the first sealing rib 211, the gap between the inner circumference of the sealing protrusion 204 and the outer circumference of the valve core 221 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 204 and the outer circumference of the valve body 210.

[0132] The end surface of the valve body 210 is provided with a second sealing rib 212, and when the water tank 200 is connected to the body 100, the second sealing rib 212 is clamped between the sealing protrusion 204 and the body 100. By providing the second sealing rib 212, the gap between the end surface of the valve body 210 and the body 100 can be filled, thereby ensuring that the liquid in the water storage space 208 will not leak from between the end surface of the valve body 210 and the body 100, and the first sealing rib 211 and the second sealing rib 212 form a double seal, further improving the sealing effect and reducing the risk of liquid leakage.

[0133] like Figure 3 and Fig.10 As shown, the body 100 includes a first housing 150 and a second housing 160. The side wall of the first housing 150 has an installation opening 151, the second housing 160 is detachably connected to the first housing 150 and covers the installation opening 151, and the first housing 150 and the second housing 160 jointly define an installation cavity 103. A core assembly is arranged in the installation cavity 103, and the core assembly is installed in the installation cavity 103 through the installation opening 151.

[0134] It should be noted that the first shell 150 and the second shell 160 can be separately set, and the first shell 150 and the second shell 160 are separately set, which means that the first shell 150 and the second shell 160 are not an integrally formed structure, but the first shell 150 and the second shell 160 can be connected by snap-on, screw-on, etc., and the embodiment of the present application is not limited to this.

[0135] The movement assembly may include a pump body 400, a battery 500, a circuit board 120 and other structures. The movement assembly may be installed in the installation cavity 103 through the installation opening 151. That is, when the water flosser 1 is assembled, since the first housing 150 has a installation opening 151 on a side wall in the circumferential direction, the movement assembly may be installed into the installation cavity 103 through the installation opening 151 to enable the movement assembly to be installed in the installation cavity 103.

[0136] Compared with the prior art in which the movement component is installed into the installation cavity from an opening opened in the length direction of the fuselage, the embodiment of the present application opens a mounting opening 151 on a side wall in the circumferential direction of the first housing 150, so that the movement component can be installed into the installation cavity 103 from the mounting opening 151, and the movement component is installed into the installation cavity 103 from a side wall in the circumferential direction of the first housing 150, that is, the installation stroke of the movement component from the mounting opening 151 into the installation cavity 103 is smaller than the installation stroke of the movement component from the opening opened in the length direction of the fuselage 100 into the installation cavity 103, thereby The installation stroke of the movement assembly from the installation opening 151 into the installation cavity 103 is shorter. Furthermore, due to the setting of the installation opening 151, the installation process of the movement assembly into the installation cavity 103 can be intuitively viewed, thereby avoiding the movement assembly from being blocked by the body 100, so that the positioning accuracy of the movement assembly in the installation cavity 103 is higher. That is, when the movement assembly is installed into the installation cavity 103 from the installation opening 151, the technician does not need to repeatedly adjust the movement assembly, thereby facilitating the assembly of the movement assembly and the body 100. In this way, the assembly efficiency of the oral irrigator 1 can be improved.

[0137] Furthermore, the first housing 150 has a first side wall and a second side wall 153, the first side wall is provided with an installation opening 151, wherein the first side wall can be fully open or partially open, the second side wall 153 is arranged adjacent to the first side wall, and the inner wall surface of the second side wall 153 is provided with a guide member 154, and the guide member 154 is used to guide the movement assembly into the installation cavity 103.

[0138] There are two second side walls 153, and the two second side walls 153 are connected to opposite sides of the first side wall. One second side wall 153 is provided with a guide member 154, and the other second side wall 153 may be provided with a guide member 154 or the other second side wall 153 may not be provided with a guide member 154, which is not specifically limited in the embodiment of the present application.

[0139] When the movement assembly is installed into the installation cavity 103 from the installation opening 151 , the guide member 154 can be used to guide the movement assembly from the installation opening 151 into the installation cavity 103 , thereby improving the assembly efficiency of the movement assembly into the installation cavity 103 .

[0140] like Figure 3 and Fig.10 As shown, the first housing 150 further comprises a third side wall 155, the third side wall 155 and the first side wall are arranged opposite to each other, and the second side wall 153 and the third side wall 155 are arranged adjacent to each other. The contour line of the outer surface of the third side wall 155 and the contour line of the outer surface of the second housing 160 are arranged axially symmetrically with respect to the mid-section plane of the oral irrigator 1.

[0141] That is, the shape of the outer surface of the third side wall 155 can be consistent with the shape of the outer surface of the second shell 160, so that the outer surface of the third side wall 155 and the outer surface of the second shell 160 are axially symmetrical about the center plane of the oral irrigator 1, so that it is convenient for the user to hold the shell assembly 10.

[0142] The second housing 160 is provided with a threaded hole, and the first housing 160 is connected to the second housing 160 through a threaded fastener. A sealing plug is provided in the threaded hole, and the sealing plug is located on the side of the threaded fastener facing the water tank, and / or a sealant is provided in the threaded hole, and the sealant is located on the side of the threaded fastener facing the water tank. In this way, the probability of the threaded fastener contacting the liquid or the outside air is reduced, and the threaded fastener is prevented from being corroded. In addition, the liquid sprayed from the nozzle 300 during the use of the water flosser 1 can be prevented from flowing into the interior of the body 100 through the threaded hole, thereby improving the circuit safety.

[0143] The core assembly includes a pump body 400, a hose 420 and an interface 430. The hose 420 is connected to the pump body 400, the interface 430 is connected to the hose 420, the second housing 160 has a second interface 205, the second interface 205 is connected to the water storage space 208, and the interface 430 is connected to the second interface 205.

[0144] It can be understood that when the water tank 200 is assembled on the second housing 160 and arranged side by side with the body 100, the second interface 205 can be connected to the water tank 200. When the water flosser 1 is working, the pump body 400 can draw the liquid in the water tank 200 to the second interface 205, and flow into the hose 420 through the interface part 430, thereby realizing the pump body 400 to draw the liquid in the water tank 200.

[0145] The first housing 150 has a first side wall and a second side wall 153, the first side wall is provided with an installation opening 151, and the first side wall and the second side wall 153 are arranged adjacent to each other. Compared with arranging the hose 420 between the third side wall 155 and the pump body 400, arranging at least a portion of the hose 420 between the second side wall 153 and the pump body 400, or arranging at least a portion of the hose 420 between the second housing 160 and the pump body 400, the hose 420 is closer to the second interface 205, which is convenient for communicating with the water tank 200.

[0146] The dental flosser 1 further comprises a clamping member, which is disposed on at least one of the second side wall 153, the second housing 160 and the pump body 400, and is used to clamp the hose 420. The clamping member may be a clamping rib or other clamping structures, which is not specifically limited in the present embodiment.

[0147] Optionally, when the hose 420 is located between the first side wall and the pump body 400, a clamping piece can be provided on the first side wall and the pump body 400. When the hose 420 is assembled, the hose 420 can be clamped between the first side wall and the pump body 400, and the hose 420 can be fixed between the first side wall and the pump body 400 by the clamping piece. In this way, the stability of the assembly of the hose 420 is improved.

[0148] Optionally, when the hose 420 is located between the second housing 160 and the pump body 400, a clamping piece can be provided on the second housing 160 and the pump body 400. When the hose 420 is assembled, the hose 420 can be clamped between the second housing 160 and the pump body 400, and the hose 420 can be fixed between the second housing 160 and the pump body 400 by the clamping piece. In this way, the assembly stability of the hose 420 is improved.

[0149] like Figure 4 and Figure 5As shown, the above-mentioned oral irrigator 1 also has a second direction (the direction indicated by arrow B in the attached drawing), and the first direction, the second direction and the length direction of the oral irrigator 1 are perpendicular to each other in pairs. The oral irrigator 1 further includes a pump body 400, a circuit board 120 and a battery 500. The pump body 400 is arranged in the fuselage 100 and communicated with the water tank 200. The pump body 400 is used to pump the liquid in the water tank 200. The circuit board 120 is arranged in the fuselage 100 and connected to the pump body 400. The battery 500 is arranged in the fuselage 100 and connected to the pump body 400. Among them, the circuit board 120 and the pump body 400 are arranged along the first direction, the battery 500 and the pump body 400 are arranged along the second direction, and the pump body 400 and the battery 500 are located on the same side of the circuit board 120 in the first direction.

[0150] In this way, the pump body 400, the circuit board 120 and the battery 500 are roughly arranged in a "pin" shape. The pump body 400, the circuit board 205 and the battery 500 are relatively close to each other in pairs, so as to shorten the length of the wires between the pump body 400, the circuit board 205 and the battery 500 in pairs, and the wiring is more convenient.

[0151] In addition, in the prior art, the pump body, the circuit board and the battery are arranged in a sandwich structure, that is, the pump body 400, the circuit board 120 and the battery 500 are stacked along the first direction, resulting in too large a size of the fuselage 100 in the first direction and too small a size of the fuselage 100 in the second direction. And when the fuselage 100 and the water tank 200 are arranged along the first direction at this time, the oral irrigator 1 is even more difficult to hold; or the pump body 400, the circuit board 120 and the battery 500 are stacked along the second direction, resulting in too small a size of the fuselage 100 in the first direction and too large a size of the fuselage 100 in the second direction. And when the fuselage 100 and the water tank 200 are arranged along the second direction at this time, the oral irrigator 1 is even more difficult to hold. The above two methods will both lead to不协调 in the size of the fuselage 100 in the first direction and the size in the second direction, and the comfort of the user holding the oral irrigator 1 is low.

[0152] The oral irrigator 1 in the embodiment of the present application is roughly arranged in a "pin" shape. The size of the fuselage 100 in the first direction and the size in the second direction are closer, the proportion of the fuselage 100 is coordinated, which is convenient for the user to hold. And the water tank 200 can not only be arranged with the fuselage 100 along the length direction of the oral irrigator 1, but also the water tank 200 can be arranged with the fuselage 100 along the first direction or the second direction, and neither will cause the oral irrigator 1 to be unable to hold, and the layout flexibility of the oral irrigator 1 is high.

[0153] The construction method of the above-mentioned oral irrigator 1 is at least one of the following:

[0154] First, the pump body 400 is connected to the circuit board 120. In this way, the pump body 400 and the circuit board 205 can be installed as a whole, and the pump body 400 and the body 100 can be connected and fixed. There is no need to fix the pump body 400 and the circuit board 205 to the body 100 separately, which reduces the number of parts, reduces the weight of the oral irrigator 1, and reduces the cost.

[0155] The second method is that the pump body 400 is connected to the battery 500. In this way, the pump body 400 and the battery 500 can be installed as a whole, and the pump body 400 and the body 100 can be connected and fixed. There is no need to fix the pump body 400 and the battery 500 to the body 100 separately, which reduces the number of parts, reduces the weight of the oral irrigator 1, and reduces the cost. Among them, the pump body 400, the circuit board 205 and the battery 500 can be assembled into a whole and then installed in the body 100, which simplifies the disassembly and assembly steps, improves the disassembly and assembly efficiency, and facilitates later maintenance.

[0156] The third type, the oral irrigator 1 further comprises a bracket, the bracket is mounted on at least one of the pump body 400 and the body 100, and at least one of the battery 500 and the circuit board 120 is mounted on the bracket. That is, the bracket can be connected to the pump body 400, the pump body 400 is connected to the body 100, or the bracket is connected to the body 100, or the bracket is connected to the pump body 400 and the body 100, so that the bracket will not be displaced in the body 100, and the relative position of the bracket and the body 100 is stable. At least one of the battery 500 and the circuit board 205 is mounted on the bracket, that is, the battery 500 can be mounted on the bracket, or the circuit board 205 can be mounted on the bracket, or the battery 500 and the circuit board 205 can be mounted on the bracket. In this way, at least one of the battery 500 and the circuit board 205 is directly fixed in relative position with the body 100, without the need to process the pump body 400, thereby reducing the processing difficulty of the pump body 400 and improving production efficiency.

[0157] like Figure 4 As shown, the pump body 400 is provided with a water inlet 209 and a water drawing assembly on the side facing away from the battery 500, and the water drawing assembly is respectively connected with the water inlet 209 and the water tank 200. In this way, the water inlet 209 and the battery 500 are located on opposite sides of the pump body 400 in the second direction, so as to prevent the battery 500 from affecting the connection between the water inlet 209 and the water inlet channel 430, and when the water inlet 209 leaks, the liquid is difficult to flow to the battery 500, so as to prevent the battery 500 from short-circuiting, thereby improving the circuit safety of the water flosser 1.

[0158] like Figure 4-Figure 6As shown, the water drawing assembly further includes a hose 420, an interface 430 and a filter 440. The hose 420 is connected to the pump body 400, the interface 430 is connected to the hose 420 and communicates with the water storage space 208, and the filter 440 is disposed on the interface 430 for filtering the liquid flowing from the interface 430 to the hose 420.

[0159] In this way, the hose 420 can connect the interface part 430 and the pump body 400, and the hose 420 can change its shape according to the internal arrangement of the pump body 100, so as to facilitate the connection between the interface part 430 and the pump body 400, thereby improving the flexibility of the layout of the oral irrigator 1.

[0160] By providing the interface member 430, the hardness of the interface member 430 can be greater than the hardness of the hose 420, and the interface member 430 can change the flow direction of the liquid, ensuring that the liquid in the first interface 105 flows more smoothly to the hose 420. In addition, the interface member 430 and the body 100 can be fixedly connected, for example, the interface member 430 and the body 100 can be positioned and connected by a threaded fastener to avoid relative displacement between the interface member 430 and the body 100, so that the relative positions of the two ends of the hose 420 and the body 100 are fixed, and the hose 420 is prevented from shaking in the body 100.

[0161] In addition, before the liquid flows into the hose 420, it will flow through the filter 440, which removes impurities in the liquid, thereby improving the cleanliness of the liquid in the hose 420, and further 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.

[0162] The pump body 400 has a first joint, the first joint is provided with a water inlet 209, the hose 420 is sleeved on the first joint, and the first joint is extended toward the interface member 430. That is, the diameter of the first joint is smaller than the diameter of the hose 420, so the flow rate of the liquid at the first joint is faster, and the speed of the liquid spraying out from the nozzle is faster.

[0163] Furthermore, since the end of the hose 420 is sleeved with the first connector 2211 , the connection between the hose 420 and the first connector is more stable, thereby improving the stability of the connection between the hose 420 and the pump body 400 .

[0164] When the first connector is extended toward the interface member 430, the hose 420 can be shortened, thereby saving the material preparation cost of the hose 420. At the same time, the first connector is arranged toward the interface member 430, which can facilitate the connection between the hose 420 and the first connector, thereby improving the assembly efficiency of the hose 420 and the pump body 400.

[0165] like Figure 6As shown, the interface member 430 has a second connector 431, the hose 420 is sleeved on the second connector 431, and the second connector 431 is extended toward the pump body 400. That is, the diameter of the second connector 431 is also smaller than the diameter of the hose 420, so when the pump body 400 is working, when the liquid in the water tank 200 is sucked into the interface member 430, since the diameter of the second connector 431 is smaller than the diameter of the hose 420, the flow rate of the liquid at the second connector 431 is faster, so that the liquid can flow quickly into the hose 420.

[0166] Since the hose 420 and the second connector 431 are sleeved, the connection between the hose 420 and the second connector 431 is relatively stable, thus improving the stability of the connection between the hose 420 and the interface 430. When the second connector 431 is extended toward the pump body 400, the hose 420 is shortened, thus saving the material preparation cost of the hose 420. Meanwhile, the second connector 431 is arranged toward the pump body 400, which can facilitate the connection between the hose 420 and the second connector 431, thereby improving the assembly efficiency of the hose 420 and the interface 430.

[0167] like Figure 6 As shown, the above-mentioned water-drawing assembly also includes a clamping member 450, which can be elastically deformed. The clamping member 450 can be made of soft rubber materials such as rubber members and silicone members. The interface member 430 is provided with a receiving groove 432, and the filter member 440 is provided in the receiving groove 432. The clamping member 450 is provided in the receiving groove 432, and the filter member 440 is clamped between the clamping member 450 and the bottom wall of the receiving groove 432.

[0168] That is to say, the filter element 440 is clamped between the interface element 430 and the clamping element 450 in the axial direction of the receiving groove 432, so as to prevent the filter element 440 from being displaced relative to the interface element 430, thereby ensuring that the liquid flowing into the hose 420 will pass through the filter element 440, thereby further improving the cleanliness of the liquid in the hose 420.

[0169] Furthermore, since the interface member 430 is provided with a receiving groove 432, the receiving groove 432 is used to receive the filter member 440 and the clamping member 450, and can fix the relative position of the clamping member 450 and the interface member 430, thereby maintaining the relative position stability among the filter member 440, the interface member 430 and the clamping member 450.

[0170] In addition, a clamping protrusion 104 is provided on the inner wall of the fuselage 100, a portion of the clamping member 450 is provided between the end face of the clamping protrusion 104 and the bottom wall of the accommodating groove 432, and another portion of the clamping member 450 is clamped between the outer peripheral surface of the clamping protrusion 104 and the inner peripheral surface of the accommodating groove 432.

[0171] That is to say, a portion of the clamping member 450 can be pressed by the end of the clamping protrusion 104 and pressed against the filter element 440. This portion can be elastically deformed and filled between the end of the clamping protrusion 104 and the bottom wall of the receiving groove 432. On the one hand, it can prevent the filter element 440 from moving in the receiving groove 432 to ensure the filtering effect. On the other hand, it can prevent liquid from flowing out from between the end of the clamping protrusion 104 and the bottom wall of the receiving groove 432, thereby reducing the probability of liquid leaking into the fuselage 100.

[0172] Another part of the clamping piece 450 can be clamped between the outer circumference of the clamping protrusion 104 and the inner circumference of the receiving groove 432. This part can undergo elastic deformation and fill the space between the outer circumference of the clamping protrusion 104 and the inner circumference of the receiving groove 432, thereby preventing liquid from leaking from between the outer circumference of the clamping protrusion 104 and the inner circumference of the receiving groove 432 into the fuselage 100, further reducing the probability of liquid leakage into the fuselage 100, and ensuring that the liquid in the receiving groove 432 flows to the hose 420 through the filter element 440, thereby reducing the probability of short circuit of electrical components in the fuselage 100.

[0173] In actual use, liquid easily adheres to the surface of the water tank 200. For example, when liquid remains on the inner wall of the water tank 200, it is not easy to clean the inner wall of the water tank 200. Moreover, if the user does not use the cleaning tool 1 for a long time, the liquid remaining on the inner wall of the water tank 200 may easily cause bacteria to grow inside the water tank 200, affecting the health and safety of the user.

[0174] Thus, the inner wall of the water tank 200 is provided with a hydrophobic layer. It is understandable that the inner wall of the water tank 200 may be provided with a hydrophobic layer as a whole or partially. The hydrophobic layer may include at least one of a hydrophobic film and a hydrophobic nanostructure. The hydrophobic film may be attached or coated on the wall of the water tank 200. The hydrophobic nanostructure may be directly formed on the wall of the water tank 200 by processing, such as forming nanoparticles, nanowires or nanotubes on the wall of the water tank 200.

[0175] Thus, in this embodiment, by providing a hydrophobic layer on the inner wall of the water tank 200, the liquid originally stuck in the water tank 200 cannot adhere to the inner wall of the water tank 200, and can flow along the inner wall of the water tank 200 to the bottom of the water tank 200, so that it is easier to be sucked clean by the pump body 400 when the cleaning tool 1 is used, so that the inner wall of the water tank 200 is not easily stained with liquid, and the risk of bacteria breeding inside the water tank 200 when the cleaning tool 1 is not used for a long time is reduced. In addition, in this way, the user does not need to take a paper towel or towel to clean the inner wall of the water tank 200 after use, which improves the convenience of the user to clean the inner wall of the water tank 200.

[0176] For another example, the outer wall of the water tank 200 is usually provided with a gap to increase the friction coefficient of the outer wall of the water tank 200, so that the user can hold the outer wall of the water tank 200 more firmly when using the cleaning tool 1, to prevent the cleaning tool 1 from falling off the user's hands or the user's unstable operation due to the user's slippery hands or the water tank 200 being too slippery. It is understandable that during the use of the cleaning tool 1, part of the liquid flushed out during flushing will flow to the outer wall of the water tank 200, and based on the existence of the gap, the liquid will easily remain in the gap, and the user usually cannot wipe out all the liquid in the gap, which will make it easy for bacteria to grow in the gap.

[0177] When the liquid adheres to the outer wall of the water tank 200, the user needs to take a tissue or a towel to clean the outer wall of the water tank 200 after using the cleaning tool 1, otherwise the user's hands, clothes or bags will get wet.

[0178] Thus, the outer wall of the water tank 200 is provided with a hydrophobic layer. Moreover, the outer wall of the water tank 200 may be provided with a hydrophobic layer as a whole or partially. The hydrophobic layer may include at least one of a hydrophobic film and a hydrophobic nanostructure. The hydrophobic film may be attached or coated on the wall surface of the water tank 200, and the hydrophobic nanostructure may be directly formed on the wall surface of the water tank 200 by processing, such as forming nanoparticles, nanowires or nanotubes on the wall surface of the water tank 200.

[0179] This embodiment provides a hydrophobic layer on the outer wall of the water tank 200, so that the liquid originally attached to the outer wall of the water tank 200 cannot adhere to the outer wall or the gaps in the outer wall, thereby reducing the risk of bacteria breeding on the outer wall and the gaps of the water tank 200. In addition, even if some liquid adheres to the outer wall and the gaps in the outer wall, the user only needs to shake the water tank 200 lightly, and the liquid will fall off, which is very convenient to operate and prevents the liquid from wetting the user's hands, clothes or bags.

[0180] Furthermore, the above-mentioned water flosser 1 is constructed in at least one of the following ways:

[0181] The first type is that the fuselage 100 and the hydrophobic layer are spaced apart, and in this case, the water tank 200 and the fuselage 100 can be in an inactive connection. The inactive connection form referred to here means that there is no relative movement between the water tank 200 and the fuselage 100, such as no relative movement, sliding or rotation between the two, etc., which can prevent the fuselage 100 from scratching the hydrophobic layer arranged on the outer wall of the water tank 200 or the hydrophobic layer arranged on the inner wall of the water tank 200 when the fuselage 100 moves relative to the water tank 200, or scraping off the hydrophobic layer to cause The water tank 200 and the fuselage 100 can be movably connected, that is, the water tank 200 and the fuselage 100 can move relative to each other, and the fuselage 100 does not contact the hydrophobic layer arranged on the outer wall of the water tank 200 or the hydrophobic layer arranged on the inner wall of the water tank 200. In this way, it can be avoided that when the fuselage 100 slides relative to the water tank 200, the fuselage 100 scratches the hydrophobic layer arranged on the outer wall of the water tank 200 or the hydrophobic layer arranged on the inner wall of the water tank 200, thereby preventing the hydrophobic layer from failing.

[0182] like Figure 2 As shown, in the second type, the water tank 200 is provided with a water inlet 209, and the water inlet 209 is provided with an end cover 600, and the end cover 600 is movably connected to the water tank 200 to open or close the water inlet 209, that is, when liquid needs to be injected into the water tank 200, the water inlet 209 can be opened by manipulating the end cover 600, and after the injection is completed, the end cover 600 can be manipulated to close the water inlet 209, which is easy to operate and can reduce the risk of liquid spilling when closing the water inlet 209. Exemplarily, the movable connection between the end cover 600 and the water tank 200 can be sliding, plugging, or hinged, etc.

[0183] Furthermore, the end cap 600 is spaced apart from the hydrophobic layer in this way, so as to prevent the end cap 600 from scratching the hydrophobic layer or scraping off the hydrophobic layer, thereby preventing the hydrophobic layer from becoming ineffective.

[0184] like Figure 2 As shown, in the third type, the water tank 200 is provided with a water inlet 209, and the water inlet 209 is provided with an end cover 600, and the end cover 600 is movably connected with the water tank 200 to open or close the water inlet 209, that is, when liquid needs to be injected into the water tank 200, the water inlet 209 can be opened by manipulating the end cover 600, and after the injection is completed, the end cover 600 can be manipulated to close the water inlet 209, which is easy to operate and can reduce the risk of liquid spillage when closing the water inlet 209. Exemplarily, the movable connection between the end cover 600 and the water tank 200 can be sliding, plugging or hinged, etc.

[0185] Furthermore, the portion of the end cap 600 extending into the water tank 200 (i.e., the plug-in section 610 and the pull-up pin 620 described below) is made of soft rubber. Thus, even if the portion of the end cap 600 extending into the water tank 200 comes into contact with the hydrophobic layer, due to the soft nature of the soft rubber itself, the portion of the end cap 600 extending into the water tank 200 is less likely to scratch or scrape off the hydrophobic layer, thereby better protecting the hydrophobic layer.

[0186] like Figure 7 As shown, in the fourth type, a water suction pipe 207 is provided in the water tank 200, and the water suction pipe 207 is connected to the fuselage 100. Through the setting of the water suction pipe 207, the amount of liquid remaining in the water tank 200 is effectively reduced, and it is beneficial to reduce the probability of leakage of the liquid in the process of being transmitted from the water tank 200 to the pump body 400. Not only that, the setting of the water suction pipe 207 can also facilitate the docking operation between the pump body 400 and the water tank 200, and the docking is faster and more accurate.

[0187] In addition, the water-drawing pipe 207 is spaced apart from the hydrophobic layer, so as to avoid the water-drawing pipe 207 scratching the hydrophobic layer or scraping off the hydrophobic layer, thereby preventing the hydrophobic layer from becoming ineffective.

[0188] like Figure 7 As shown, in the fifth type, a water suction pipe 207 is provided in the water tank 200, and the water suction pipe 207 is connected to the fuselage 100. Through the setting of the water suction pipe 207, the amount of liquid remaining in the water tank 200 is effectively reduced, and it is beneficial to reduce the probability of leakage of the liquid in the process of being transmitted from the water tank 200 to the pump body 400. Not only that, the setting of the water suction pipe 207 can also facilitate the docking operation between the pump body 400 and the water tank 200, and the docking is faster and more accurate.

[0189] In addition, the water-drawing pipe 207 can be deformed when in contact with the hydrophobic layer. Thus, even if the water-drawing pipe 207 moves relative to the water tank 200 and comes into contact with the hydrophobic layer, the soft nature of the hose 420 can effectively reduce the probability of the water-drawing pipe 207 as the hose 420 scratching or scraping off the hydrophobic layer.

[0190] like Figure 2 As shown, the above-mentioned water flosser 1 further includes a nozzle 300 and an end cover 600. The nozzle 300 is connected to the top of the body 100, and the top of the water tank 200 or the top of the body 100 is provided with a water inlet 209, which is communicated with the water storage space 208.

[0191] That is to say, no matter whether the water inlet 209 is arranged on the body 100 or the water tank 200, the water inlet 209 is located at the top of the entire irrigator 1 (except the part other than the nozzle 300). In this case, when water is injected into the irrigator 1, the irrigator 1 still maintains a vertical state (that is, the length direction of the irrigator 1 extends in the up and down direction). The state of the irrigator 1 when water is injected is consistent with the state of the irrigator 1 when in use. There is no need to flip or rotate the irrigator 1, so that the user does not need to excessively turn his wrist, and the use of the irrigator 1 is more convenient.

[0192] In addition, the end cover 600 can be flipped between an open state and a closed state relative to the water inlet 209. When the end cover 600 is switched from the closed state to the open state, the end cover 600 flips toward the direction of the nozzle 300. When the end cover 600 is in the closed state, the water inlet 209 is sealed. When the end cover 600 is in the open state, it abuts against the nozzle 300, the water inlet 209 is open, and the water storage space 208 is connected to the atmosphere through the water inlet 209.

[0193] In this way, when the end cover 600 is in the closed state, the water inlet 209 is sealed, which prevents the liquid in the water tank 200 from leaking from the water inlet 209 on the one hand, and prevents external dirt and impurities from entering the water tank 200 on the other hand, thereby ensuring the cleanliness of the liquid in the water tank 200, and making the oral irrigator 1 safer for cleaning the oral cavity. When the end cover 600 is in the open state, the end cover 600 stops at the nozzle 300, and the free end of the end cover 600 and the nozzle 300 are roughly in the same position. Therefore, while the water injection device avoids the nozzle 300, it also avoids the end cover 600 to a certain extent, and the human hand and the nozzle 300 are less obstructive to the water injection device. The relative position between the water injection device 1 and the water injection device is more flexible, and it is more convenient to inject water into the water injection device 1, which is convenient for the user to fill water after the end cover 600 is opened.

[0194] like Figure 2 As shown, further, the end cover 600 is provided with an insert section 610 and a pull-up pin 620, the insert section 610 is inserted in the water inlet 209 and is sealed with the inner wall of the water inlet 209, and in the radial direction of the water flosser 1, a through hole 621 is provided between the water inlet 209 and the nozzle 300, the pull-up pin 620 is inserted in the through hole 621, and the pull-up pin 620 is limited by the side wall of the through hole 621 along the axial direction of the through hole 621.

[0195] In the process of the end cover 600 being turned from the closed state to the open state, the plug-in portion 410 is gradually pulled out from the water inlet 209. In this way, the plug-in portion 410 can seal the water inlet 209, which can prevent the liquid in the water tank 200 from leaking from the water inlet 209, and prevent the external dirt and impurities from entering the water tank 200, thereby ensuring the cleanliness of the liquid in the water tank 200, and making the oral irrigator 1 safer for cleaning the oral cavity.

[0196] When the end cover 600 is switched from the open state to the closed state, the plug-in portion 410 is pulled out from the water inlet 209 and flipped in the direction of the nozzle 300. During this process, the lifting nail 620 gradually moves upward. When the end cover 600 stops at the nozzle 300, the lifting nail 620 and the side walls of the through hole 621 can stop against each other to prevent the lifting nail 620 from being separated from the through hole 621. In this way, when the end cover 600 is switched from the closed state to the open state, the relative position between the lifting nail 620 and the water tank 200 and the body 100 is determined, the plug-in portion 410 is more accurately inserted into the water inlet 209, and the end cover 600 is more convenient to switch between the open state and the closed state.

[0197] Since the through hole 621 is located between the water inlet 209 and the nozzle 300, the movable size of the lifting nail 620 is smaller than the movable size of the plug-in portion 410, so that the lifting nail 620 can be prevented from being separated from the through hole 621 when the end cover 600 is in the open state. In particular, when the end cover 600 is in the closed state, the size of the lifting nail 620 can be larger than the size of the plug-in portion 410 in the length direction of the oral irrigator 1, which can further prevent the lifting nail 620 from being separated from the through hole 621 when the end cover 600 is in the open state.

[0198] like Figure 1 and Figure 3 As shown, the upper tooth flusher 1 further includes a clamping member 310, a reset member 320 and a disassembly button 330. The clamping member 310 is movably disposed in the body 100. When the clamping member 310 contacts the nozzle 300, the relative position of the nozzle 300 and the body 100 is limited. When the clamping member 310 is separated from the nozzle 300, the nozzle 300 and the body 100 can be separated. The reset member 320 is connected to the clamping member 310 and the body 100 to make the clamping member 310 have a tendency to move close to the nozzle 300. The disassembly button 330 is disposed in the body 100 and connected to the clamping member 310. At least a part of the disassembly button 330 is located outside the body 100. Pressing the disassembly button 330 drives the clamping member 310 to separate from the nozzle 300.

[0199] The user can press the disassembly button 330 to separate the nozzle 300 from the body 100, thereby avoiding accidental separation of the nozzle 300 and the body 100, and facilitating replacement of the nozzle 300 with a higher degree of cleanliness.

[0200] The top of the body 100 is provided with an insertion port 340, which is used to plug the nozzle 300, and the insertion port 340 is located at the center of the top of the body 100. In this way, the top of the body is evenly stressed, the insertion port 340 is not easily damaged, and the connection between the nozzle 300 and the body 100 is stable.
