[0032] The following describes the oral irrigator 1 according to an embodiment of the present application with reference to the accompanying drawings.

[0033] As shown in FIG. 1 and FIG. 2 , the oral irrigator 1 of the embodiment of the present application includes a body 100 and a water tank 200 .

[0034] The top of the body 100 can be connected to the nozzle 300. The water tank 200 is connected to the body 100. The water tank 200 defines a water storage space 208 or jointly defines the water storage space 208 with the body 100. The water storage space 208 is used to store liquid for oral hygiene, such as water or mouthwash. The pump body 400 is disposed within the body 100 and is used to pump the liquid in the water storage space 208 to the nozzle 300.

[0035] The buffer pad can be arranged between the machine body 100 and the water tank 200, on one hand, to increase the friction between the machine body 100 and the water tank 200, and to keep the relative position between the machine body 100 and the water tank 200, and on the other hand, to reduce the collision noise between the machine body 100 and the water tank 200.

[0036] In addition, the oral irrigator 1 has a first direction (indicated by arrow A in the drawings), the first direction is perpendicular to the length direction of the oral irrigator 1 (indicated by arrow C in the drawings), and at least a part of the water tank 200 and the machine body 100 are arranged along the first direction, so that the center of gravity of the liquid in the water tank 200 is increased.

[0037] Since the height of the nozzle 300 is usually higher than that of the water tank 200, by arranging at least a part of the water tank 200 and the machine body 100 along the first direction, the center of gravity of the liquid in the water tank 200 is increased, 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 for pumping and spraying the liquid in the water tank 200 to the nozzle 300 is smaller, the energy can be saved, and the endurance of the oral irrigator 1 is improved.

[0038] 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 machine body 100 in the length direction of the oral irrigator 1 is shortened, which is beneficial to the stability of the oral irrigator 1 and avoids shaking of the oral irrigator 1 when placed.

[0039] As shown in FIG. 1, the arrangement of the above-mentioned oral irrigator 1 is at least one of the following:

[0040] Firstly, the water tank 200 and the machine body 100 are arranged along the first direction, that is, the water tank 200 is entirely located on the side of the machine body 100 in the first direction, so that the sizes of the water tank 200 and the machine body 100 in the length direction of the oral irrigator 1 are smaller;

[0041] Secondly, a part of the water tank 200 and the machine body 100 are arranged along the length direction of the oral irrigator 1, and the other part of the water tank 200 and the machine body 100 are arranged along the first direction, so that the water tank 200 limits the position of the machine body 100 in the length direction and the first direction of the oral irrigator 1, and the water tank 200 and the machine body 100 can support each other in the length direction of the oral irrigator 1, and the water tank 200 and the machine body 100 are not easy to separate;

[0042] Thirdly, a part of the machine body 100 and the water tank 200 are arranged along the length direction of the oral irrigator 1, and the other part of the machine body 100 and the water tank 200 are arranged along the first direction, so that the machine body 100 limits the position of the water tank 200 in the length direction and the first direction of the oral irrigator 1, and the water tank 200 and the machine body 100 can support each other in the length direction of the oral irrigator 1, and the water tank 200 and the machine body 100 are not easy to separate.

[0043] Further, 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 facilitates the arrangement of components in the body 100 and increases the volume of the water tank 200, and the oral irrigator 1 has stronger endurance.

[0044] 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, and the operation module 130 and the display module 140 are generally arranged on the body 100, the outer circumferential surface of the body 100 is convenient for the user to touch, facilitating the operation of the operation module 130 and the display module 140, and the operation module 130 and the display module 140 have more arrangement positions in the length direction of the oral irrigator 1, improving the structural flexibility of the oral irrigator 1.

[0045] As shown in FIGS. 1 and 2, the top of the water tank 200 can be arranged 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, so that there is no step between the top of the water tank 200 and the top of the body 100, avoiding the accumulation of impurities between the top of the water tank 200 and the top of the body 100, and reducing the probability of bacterial growth in the oral irrigator 1.

[0046] Since the top surface of the water tank 200 does not exceed the top surface of the body 200, when the nozzle 300 extends into the oral cavity, the water tank 200 will not collide with the teeth; the height of the top surface of the body 200 which the water tank 200 does not exceed, the water inlet 209 of the water tank 200 can be arranged at the top end, and the water tank 200 does not need to be limited by the body 200 when filling water, making it more convenient to fill water, and since the oral irrigator 1 is inclined when in use, since the nozzle 300 is on the side of the body 100, the water flow discharged enters the oral cavity and flows downward, flows to the top of the water tank 200, and then flows along the direction of gravity, which will flow to the gap between the body 100 and the water tank 200, and dirt is easily accumulated between the contact surfaces of the body 100 and the water tank 200, and in the case where the connecting port (for example, the first interface 105 and the second interface 205) is arranged on the side of the body 100 facing the water tank 200 and the side of the water tank 200 facing the body 100, the above connecting port is also easily contaminated, therefore, the top surface of the body 200 does not exceed the top surface of the water tank 200, preventing the formation of a step and reducing the probability of bacterial growth.

[0047] In addition, the bottom of the water tank 200 can be arranged flush with the bottom of the body 100, 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 closer, which is beneficial to the stability of the oral irrigator 1, further avoiding the oral irrigator 1 from shaking when placed, and the power required for pumping water is smaller, which is beneficial to energy saving and has strong endurance;

[0048] In some embodiments of the present application, the top of the water tank 200 is in the same plane as the top of the body 100, and the top of the water tank 200 and the top of the body 100 can be 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 body 100.

[0049] As shown in FIGS. 1 and 2, in the first direction, the side of the body 100 facing away from the water tank 200 is provided with an operation module 130 and a display module 140. The operation module 130 and the display module 140 can be connected to the circuit board 120.

[0050] That is, 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, at least a part of the display module 140 is exposed from the body 100 to facilitate the user to view the content displayed by the display module 140, and the operation module 130 can be a key, a joystick, a sliding key, etc., at least a part of the operation module 130 is exposed from the body 100 to facilitate the user to operate the operation module 130 to control the oral irrigator 1.

[0051] In addition, the operation module 130 is located on the opposite side of the water tank 200 in the first direction of the body 100, and when the user applies pressure to the operation module 130, the body 100 moves in the direction of the water tank 200 under the force, avoiding the dislocation of the body 100 and the water tank 200 in the second direction under the force.

[0052] In addition, the operation module 130 is located above the display module 140, and during the use of the oral irrigator 1, the user's fingers can always be placed on the operation module 130, and when the liquid sprayed by the nozzle 300 flows downward, the fingers will prevent the liquid from continuing to flow downward, reducing the probability of the display module 140 being covered with liquid, and the user's observation of the display module 140 is always clear, providing a better experience.

[0053] The above-mentioned water tank 200 and 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.

[0054] 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, which is easily depleted during use of the oral irrigator 1, requiring repeated water filling, and providing a poor user experience, or the cross-sectional area of the body 100 is too large, resulting in inconvenience in holding the oral irrigator 1 and excessive weight;

[0055] When the ratio of S1 to S2 is greater than 2, the cross-sectional area of the water tank 200 is too large, which leads to inconvenience in holding 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 is more inconvenient to hold. Or the cross-sectional area of the machine body 100 is too small, and the components in the machine body 100 are arranged too compactly, which is not convenient for heat transfer and easily leads to accelerated aging of the components in the machine body 100.

[0056] 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 and the cross-sectional area of the machine body 100 are relatively close, and the cross-sectional area of the water tank 200 and the cross-sectional area of the machine body 100 are moderate. On the one hand, the water tank 200 can store sufficient liquid for cleaning the oral cavity, and the components in the machine body 100 can be relatively dispersed to avoid heat accumulation and reduce the aging speed. On the other hand, the oral irrigator 1 is convenient to hold, and the use is optimized.

[0057] The water tank 200 and the machine body 100 are arranged along the first direction. The size of the water tank 200 in the first direction is L1, and the cross-sectional area of the machine body 100 is L2. 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.

[0058] 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, which leads to too little liquid stored in the water tank 200. During use of the oral irrigator 1, the liquid is easily consumed, and repeated water filling is required, which leads to poor user experience. Or the size of the machine body 100 in the first direction is too large, which leads to inconvenience in holding the oral irrigator 1 and the oral irrigator 1 is too heavy.

[0059] 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 leads to inconvenience in holding 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 is more inconvenient to hold. Or the size of the machine body 100 in the first direction is too small, and the components in the machine body 100 are arranged too compactly, which is not convenient for heat transfer and easily leads to accelerated aging of the components in the machine body 100.

[0060] 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 and the size of the machine body 100 in the first direction are relatively close, and the size of the water tank 200 in the first direction and the size of the machine body 100 in the first direction are moderate. On the one hand, the water tank 200 can store sufficient liquid for cleaning the oral cavity, and the components in the machine body 100 can be relatively dispersed to avoid heat accumulation and reduce the aging speed. On the other hand, the oral irrigator 1 is convenient to hold, and the use is optimized.

[0061] The oral irrigator 1 has a cross-sectional area of no more than 35 cm 2 . The oral irrigator 1 can have a cross-sectional area of no less than 5 cm 2 . That is, no matter whether the side of the body 100 is connected with the water tank 200 or the end of the body 100 is connected with the water tank 200, the cross-sectional area of the oral irrigator 1 is no more than 35 cm 2 .

[0062] For example, the cross-sectional area of the oral irrigator 1 can be 5 cm 2 , 6 cm 2 , 7 cm 2 , 8 cm 2 , 9 cm 2 , 10 cm 2 , 11 cm 2 , 12 cm 2 , 13 cm 2 , 14 cm 2 , 15 cm 2 , 16 cm 2 , 17 cm 2 , 18 cm 2 , 19 cm 2 , 20 cm 2 , 21 cm 2 , 22 cm 2 , 23 cm 2 , 24 cm 2 , 25 cm 2 , 26 cm 2 , 27 cm 2 , 28 cm 2 , 29 cm 2 , 30 cm 2 , 31 cm 2 , 32 cm 2 , 33 cm 2 , 34 cm 2 , or 35 cm 2 .

[0063] In this way, the cross-sectional area of the oral irrigator 1 is small, which is convenient for the user to hold, and the user can more easily adjust the posture of the oral irrigator 1 when the oral irrigator 1 is used to clean the oral cavity, so that the liquid of the oral irrigator 1 can be sprayed to each region of the oral cavity, so as to avoid the existence of a cleaning dead angle in the oral cavity, achieve all-around cleaning of the oral cavity, and achieve more thorough cleaning effect and better user experience.

[0064] As shown in FIG. 1-2, the oral irrigator 1 also has a second direction (indicated by arrow B in the figure), the first direction, the second direction and the length direction of the oral irrigator 1 are perpendicular to each other, the size of the oral irrigator 1 in the first direction is greater than the size of the oral irrigator 1 in the second direction, and the oral irrigator 1 can have an elliptical structure or a long circular structure, which conforms to the holding habit of the human hand. Moreover, the water tank 200 and the machine body 100 are smoothly connected. In this way, the water tank 200 and the machine body 100 do not form a stepped structure, which on the one hand optimizes the holding feeling of the oral irrigator 1, makes the oral irrigator 1 more fit the palm, avoids the palm to be suspended, and on the other hand, the connection between the water tank 200 and the machine body 100 is easy to clean, and is not easy to hide dirt and accumulate dust, which is beneficial to realize the cleaning of the oral irrigator 1.

[0065] The water tank 200 and the machine body 100 are arranged along the first direction, and the cross-sectional area of the water tank 200 is constant. In this way, the gravity of the water tank 200 in the length direction of the oral irrigator 1 is uniform, avoiding the situation that the upper part of the water tank 200 is heavier than the lower part, the oral irrigator 1 is stable when placed, and the cross-sectional area of the lower part of the water tank 200 is prevented from being too large to cause poor holding comfort. Moreover, the lower part of the water tank 200 is closer to the wrist, and if the volume of the lower part of the water tank 200 is large, it will affect the rotation of the wrist, so the oral irrigator may not be able to clean each area of the oral cavity.

[0066] The water tank 200 and the machine body 100 are arranged along the first direction, and the cross-sectional area of the machine body 100 is constant. In this way, the gravity of the machine body 100 in the length direction of the oral irrigator 1 is uniform, avoiding the situation that the upper part of the machine body 100 is heavier than the lower part, the oral irrigator 1 is stable when placed, and the cross-sectional area of the lower part of the machine body 100 is prevented from being too large to cause poor holding comfort. Moreover, the lower part of the machine body 100 is closer to the wrist, and if the volume of the lower part of the machine body 100 is large, it will affect the rotation of the wrist, so the oral irrigator may not be able to clean each area of the oral cavity.

[0067] The water tank 200 and the machine body 100 are detachable, and the water tank 200 and the machine body 100 are separated along the first direction. Since the first direction is perpendicular to the gravity, the water tank 200 and the machine body 100 will not be separated due to the influence of gravity, avoiding the situation that the oral irrigator is accidentally separated and damaged, and the structure of the oral irrigator 1 is more reasonable.

[0068] As shown in the figure, one of the machine body 100 and the water tank 200 is provided with a protruding part 202 and the other is provided with a recessed part 102, and the protruding part 202 is inserted into the recessed part 102. The cross-sectional area of the protruding part 202 gradually decreases towards the recessed part 102, and the shape of the recessed part 102 is matched with the shape of the protruding part 202, which can play the role of installation guide, facilitating quick positioning and assembly.

[0069] The positioning between the body 100 and the water tank 200 is facilitated by the cooperation of the protrusions 202 and the recesses 102, the required installation time between the body 100 and the water tank 200 is shortened, the production efficiency is improved, and the user can conveniently assemble and use the oral irrigator 1 during use, thereby improving the user experience. In addition, the protrusions 202 and the recesses 102 can support the body 100 and the water tank 200 to prevent misalignment of the body 100 and the water tank 200 in the length direction of the oral irrigator 1.

[0070] In addition, other connection structures can be provided between the body 100 and the water tank 200, such as buckle connection, sliding connection, magic tape connection, screw connection, magnetic attraction connection, etc., so that the connection between the body 100 and the water tank 200 is reliable.

[0071] Further, the protrusions 202 are a plurality of protrusions, the recesses 102 are a plurality of recesses, the plurality of protrusions 202 correspond to the plurality of recesses 102 one by one, and the plurality of protrusions 202 are arranged at intervals in the length direction of the oral irrigator 1. The distance between the uppermost protrusion 202 and the top of the water tank 200 is less 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 less than the distance between the protrusion 202 and the middle of the water tank 200.

[0072] In this way, the uppermost protrusion 202 is closer to the top end of the water tank 200, and the lowermost protrusion 202 is closer to the bottom end of the water tank 200. The connection force between the water tank 200 and the body 100 can act on the upper and lower ends of the water tank 200, which can prevent the water tank 200 from rotating relative to the body 100, and can make the relative position between the water tank 200 and the body 100 more stable.

[0073] Specifically, one of the protrusions 202 and the recesses 102 is provided with a first magnetic attraction piece 101 and the other is provided with a second magnetic attraction piece 201, and the first magnetic attraction piece 101 and the second magnetic attraction piece 201 are magnetically attracted to each other. The gap between the first magnetic attraction piece 101 and the second magnetic attraction piece 201 can be not greater than 3 mm to improve the magnetic attraction force between the first magnetic attraction piece 101 and the second magnetic attraction piece 201.

[0074] For example, the first magnetic attraction piece 101 can be a permanent magnet, such as a magnet, and the second magnetic attraction piece 201 can also be a permanent magnet, such as a magnet, and the opposite polarities of the first magnetic attraction piece 101 and the second magnetic attraction piece 201 are opposite, and of course the second magnetic attraction piece 201 can also be a metal (such as iron) that can be magnetically attracted and other substances that can be magnetically attracted; the second magnetic attraction piece 201 can be a permanent magnet, such as a magnet, and the first magnetic attraction piece 101 can also be a permanent magnet, such as a magnet, and the polarities of the first magnetic attraction piece 101 and the second magnetic attraction piece 201 are opposite, and of course the first magnetic attraction piece 101 can also be a metal (such as iron) that can be magnetically attracted or other substances that can be magnetically attracted.

[0075] By setting the first magnetic attraction member 101 and the second magnetic attraction member 201, in the process of assembling the oral irrigator 1, the magnetic attraction 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 the user to manually align, making installation more convenient, and the magnetic attraction force between the first magnetic attraction member 101 and the second magnetic attraction member 201 can prevent the water tank 200 and the body 100 from separating, and play a role in fixing.

[0076] In the case of connecting the water tank 200 and the body 100 at the end, 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 and the body 100 remain connected, wherein the gravity of the water tank 200 refers to the gravity of the water tank 200 itself when the water storage space 208 202 is empty of liquid. After the first magnetic attraction member 101 and the second magnetic attraction member 201 are aligned, it can be ensured that whether there is water in the wheel water storage space 208, the water tank 200 can be stably connected to the body 100, avoiding separation of the water tank 200 and the body 100, and use is reliable.

[0077] In the case of connecting the water tank 200 and the body 100 at the side, the water tank 200 and the body 100 are connected at least by the magnetic attraction force, that is, the water tank 200 and the body 100 can be connected only by the magnetic attraction force, or the water tank 200 and the body 100 are connected not only by the magnetic attraction force, but also have other forces that maintain the relative position between the water tank 200 and the body 100. Due to the presence of the magnetic attraction force, even if other forces exist, the other forces can be reduced to some extent, the implementation of the other forces is more flexible, the structure of the oral irrigator 1 is more diverse, which is conducive to improving the applicability of the oral irrigator 1 and reducing the cost.

[0078] Further, the above-mentioned body 100 includes a pump body 400, and the oral irrigator 1 is arranged in at least one of the following ways:

[0079] First, at least part of the first magnetic attraction member 101 is arranged in a staggered manner with the motor 410 of the pump body 400 in the length direction of the oral irrigator 1;

[0080] Second, at least part of the second magnetic attraction member 201 is arranged in a staggered manner with the motor 410 of the pump body 400 in the length direction of the oral irrigator 1;

[0081] Third, 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 in a plane perpendicular to the length direction of the oral irrigator 1;

[0082] Fourthly, at least part of the orthographic projection of the second magnetic attraction member 201 is arranged in dislocation with the orthographic projection of the motor 410 of the pump body 400 in the plane perpendicular to the length direction of the oral irrigator 1.

[0083] In this way, the first magnetic attraction member 101 and the second magnetic attraction member 201 can be arranged in dislocation with the motor 410, reducing the interference of the first magnetic attraction member 101 and the second magnetic attraction member 201 with the internal magnet of the motor 410, avoiding the occurrence or power recession of the motor 410, ensuring the normal use of the motor 410, and prolonging the service life of the motor 410.

[0084] As shown in FIGS. 6-8, the above-mentioned machine body 100 and the water tank 200 are detachably connected, the machine body 100 is provided with a first interface 105, the water tank 200 is provided with a second interface 205, the first interface 105 is in communication with the pump body 400 in the machine body 100, and the second interface 205 is provided with a valve body 210; when the water tank 200 is connected with the machine body 100, the valve body 210 is opened, and the first interface 105 and the second interface 205 are in communication; when the water tank 200 is separated from the machine body 100, the valve body 210 is closed, and the communication between the first interface 105 and the second interface 205 is disconnected.

[0085] The water tank 200 can be supplemented with liquid when the machine body 100 is connected with the water tank 200, and the water tank 200 can also be supplemented with liquid when the machine body 100 is separated from the water tank 200, so that the water tank 200 has more diversified and flexible ways of being supplemented with liquid, and the machine body 100 and the water tank 200 are placed separately, which is convenient for carrying.

[0086] When the machine body 100 is connected with the water tank 200, the valve body 210 is opened, so that 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 machine body 100 is separated from the water tank 200, the valve body 210 is closed, so that 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 second interface 205 has high flexibility, and the water tank 200 is relatively small in size relative to the oral irrigator 1, which is convenient for users to hold, and it is more convenient to supplement the liquid in the water tank 200, and the water tank 200 and the machine body 100 are placed and carried more conveniently after being separated. When the water tank 200 is supplemented with liquid, the opening direction of the water inlet 209 is upward, and the water inlet 209 is located above the second interface 205 and the water storage space 208.

[0087] Further, as shown in FIGS. 6-8, the first interface 105 is provided with a stopper 106, and when the water tank 200 is connected to the body 100, the stopper 106 abuts against the valve body 210 to open the valve body 210. In this way, the opening and closing state of the valve body 210 is directly linked to the separation and connection between the water tank 200 and the body 100, which helps to ensure that the valve body 210 is closed to the second interface 205 when the water tank 200 is separated from the body 100, and that the second interface 205 is open when the water tank 200 is connected to the body 100, so that the second interface 205 is in communication with the first interface 105, facilitating the normal operation of the oral irrigator 1 and the separate operation of the water tank 200 for replenishing liquid.

[0088] As shown in FIG. 2, specifically, the water tank 200 and the body 100 are arranged along a first direction, the first interface 105 is arranged at the bottom of the side of the body 100, and the second interface 205 is arranged at the bottom of the 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 water suction pipe 207 connected to the second interface 205 is located in the water storage space 208 and faces the bottom wall of the water storage space 208, the length of the water suction pipe 207 can be shortened, the liquid residue in the water tank 200 is less, and the distance between the first interface 105 and the second interface 205 is closer, so that the communication between the first interface 105 and the second interface 205 can be achieved without additional communication structure, and the structure of the oral irrigator 1 is simpler.

[0089] As shown in FIGS. 6-8, 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, and 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.

[0090] For example, the body 100 is provided with the sealing protrusion 204 surrounding the first interface 105, the water tank 200 is provided with the sealing groove 107, the bottom wall of the sealing groove 107 is provided with the second interface 205, and the sealing protrusion 204 is inserted into the sealing groove 107; or the body 100 is provided with the sealing groove 107, the bottom wall of the sealing groove 107 is provided with the first interface 105, the water tank 200 is provided with the 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.

[0091] 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 support in the length direction of the oral irrigator 1, 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 separation of the body 100 and the water tank 200;

[0092] When the end of the body 100 is connected with the water tank 200, the sealing protrusion 204 and the sealing groove 107 cooperate to limit the position in the radial direction of the oral irrigator 1, 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.

[0093] As shown in FIGS. 6-8, in the case where the sealing protrusion 204 is arranged on the outer surface of the water tank 200, the sealing protrusion 204 surrounds the second interface 205. The outer circumferential surface of the valve body 210 is provided with a first sealing rib 211 that cooperates with the inner circumferential surface of the sealing protrusion 204. By arranging the first sealing rib 211, the gap between the inner circumferential surface of the sealing protrusion 204 and the outer circumferential surface of the valve core 221 can be filled, thereby ensuring that the liquid in the water storage space 208 does not leak from between the inner circumferential surface of the sealing protrusion 204 and the outer circumferential surface of the valve body 210.

[0094] The end surface of the valve body 210 is provided with a second sealing rib 212 that is clamped between the sealing protrusion 204 and the body 100 when the water tank 200 is connected with the body 100. By arranging 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 does 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.

[0095] As shown in FIGS. 3, 4 and 10, the above-mentioned body 100 includes a first casing 150 and a second casing 160. The side wall of the first casing 150 has a mounting opening 151, and the second casing 160 is detachably connected with the first casing 150 and covers the mounting opening 151, and the first casing 150 and the second casing 160 together define a mounting cavity 103. The mounting cavity 103 is provided with a movement core assembly 700, and the movement core assembly 700 is installed in the mounting cavity 103 through the mounting opening 151.

[0096] It should be noted that the first casing 150 and the second casing 160 can be separately arranged, and the separate arrangement of the first casing 150 and the second casing 160 means that the first casing 150 and the second casing 160 are not integrally formed structures, but the first casing 150 and the second casing 160 can be connected by clamping, screwing or the like, which is not limited in the present application.

[0097] The machine core assembly 700 can be a structure including the pump body 400, the battery 500, the circuit board 120, and the like. The machine core assembly 700 can be installed in the installation cavity 103 through the installation opening 151, that is, when the oral irrigator 1 is assembled, the machine core assembly 700 can be installed into the installation cavity 103 from the installation opening 151 due to the installation opening 151 on one side wall of the first shell 150 in the circumferential direction, so as to realize the installation of the machine core assembly 700 into the installation cavity 103.

[0098] Compared with the prior art in which the machine core assembly is installed into the installation cavity from the opening in the length direction of the machine body, the installation opening 151 is arranged on one side wall of the first shell 150 in the circumferential direction in the embodiment of the present application, so that the machine core assembly 700 can be installed into the installation cavity 103 from the installation opening 151, and the machine core assembly 700 is installed into the installation cavity 103 from one side wall of the first shell 150 in the circumferential direction, that is, the installation stroke of the machine core assembly 700 from the installation opening 151 into the installation cavity 103 is smaller than the installation stroke of the machine core assembly 700 into the installation cavity 103 along the opening in the length direction of the machine body 100, so that the installation stroke of the machine core assembly 700 into the installation cavity 103 from the installation opening 151 is shorter. In addition, the installation process of the machine core assembly 700 into the installation cavity 103 can be directly observed due to the arrangement of the installation opening 151, so that the machine core assembly 700 is not blocked by the machine body 100, and the positioning accuracy of the machine core assembly 700 into the installation cavity 103 is higher, that is, the technician does not need to repeatedly adjust the machine core assembly 700 when the machine core assembly 700 is installed into the installation cavity 103 from the installation opening 151, so that the assembly of the machine core assembly 700 and the machine body 100 is facilitated, and thus the assembly efficiency of the oral irrigator 1 can be improved.

[0099] Further, the first shell 150 has a first side wall and a second side wall 153. The first side wall is provided with the installation opening 151. The first side wall can be completely open or partially open. The second side wall 153 is arranged adjacent to the open side wall. The inner wall surface of the second side wall 153 is provided with a guide 154. The guide 154 is used to guide the machine core assembly 700 to be installed into the installation cavity 103.

[0100] The second side wall 153 is two, 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 154. The other second side wall 153 can be provided with a guide 154 or can not be provided with a guide 154. The embodiment of the present application does not make specific limitation in this regard.

[0101] When the movement assembly 700 is assembled into the installation cavity 103 from the installation opening 151, the guide 154 can be used to guide the movement assembly 700 to be assembled into the installation cavity 103 from the installation opening 151, so that the assembly efficiency of the movement assembly 700 to be assembled into the installation cavity 103 is improved.

[0102] As shown in FIG. 3 and FIG. 10, the first housing 150 further has a third side wall 155, the third side wall 155 is oppositely arranged with the first side wall, and the second side wall 153 and the third side wall 155 are adjacently arranged. The contour line of the outer surface of the third side wall 155 is arranged to be axially symmetrical with the contour line of the outer surface of the second housing 160 about the median plane of the oral irrigator 1.

[0103] 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 housing 160, so that the outer surface of the third side wall 155 and the outer surface of the second housing 160 are arranged to be axially symmetrical about the median plane of the oral irrigator 1, so that the user can hold the housing assembly 10 more conveniently.

[0104] The second housing 160 is provided with a threaded hole, and the first housing 160 is connected with the second housing 160 through a threaded fastener. The threaded hole is provided with a sealing plug, and the sealing plug is located on the side of the threaded fastener facing the water tank, and / or the threaded hole is provided with sealing glue, and the sealing glue is located on the side of the threaded fastener facing the water tank. In this way, the probability of the threaded fastener contacting liquid or external air is reduced, corrosion of the threaded fastener is avoided, and in addition, the liquid sprayed by the nozzle 300 during use of the oral irrigator 1 can be prevented from flowing into the interior of the machine body 100 through the threaded hole, improving the safety of the circuit.

[0105] The movement assembly 700 includes the pump body 400, the hose 420, and the interface piece 430. The hose 420 is in communication with the pump body 400, the interface piece 430 is in communication with the hose 420, the second housing 160 has a second interface 205, the second interface 205 is in communication with the water storage space 208, and the interface piece 430 is in communication with the second interface 205.

[0106] It can be understood that when the water tank 200 is assembled on the second housing 160 and arranged side by side with the machine body 100, the second interface 205 can be in communication with the water tank 200, and when the oral irrigator 1 is working, the pump body 400 can suck the liquid in the water tank 200 to the second interface 205, and flow into the hose 420 through the interface piece 430, so as to realize the pumping of the liquid in the water tank 200 by the pump body 400.

[0107] The first shell 150 has a first side wall and a second side wall 153, the first side wall is provided with the mounting 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, at least a part of the hose 420 is arranged between the second side wall 153 and the pump body 400, or at least a part of the hose 420 is arranged between the second shell 160 and the pump body 400, which is closer between the hose 420 and the second interface 205, and facilitates communication with the water tank 200.

[0108] The oral irrigator 1 further comprises a clamping member arranged on at least one of the second side wall 153, the second shell 160 and the pump body 400, and used for clamping the hose 420. The clamping member can be a clamping rib or other clamping structure, and the embodiments of the present application do not make specific limitations in this regard.

[0109] Optionally, when the hose 420 is arranged between the first side wall and the pump body 400, the clamping member can be arranged 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 is fixed between the first side wall and the pump body 400 through the clamping member. In this way, the stability of the assembly of the hose 420 is improved.

[0110] Optionally, when the hose 420 is arranged between the second shell 160 and the pump body 400, the clamping member can be arranged on the second shell 160 and the pump body 400. When the hose 420 is assembled, the hose 420 can be clamped between the second shell 160 and the pump body 400, and the hose 420 is fixed between the second shell 160 and the pump body 400 through the clamping member. In this way, the stability of the assembly of the hose 420 is improved.

[0111] As shown in FIGS. 4 and 5, the oral irrigator 1 further has a second direction (the direction indicated by the arrow B in the drawing), the first direction, the second direction and the length direction of the oral irrigator 1 are perpendicular to each other. The oral irrigator 1 further comprises a pump body 400, a circuit board 120 and a battery 500. The pump body 400 is arranged in the machine body 100 and communicates with the water tank 200, and is used for pumping liquid in the water tank 200. The circuit board 120 is arranged in the machine body 100 and connected with the pump body 400. The battery 500 is arranged in the machine body 100 and connected with 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.

[0112] In this way, the pump body 400, the circuit board 120 and the battery 500 are arranged in a substantially "pin" shape, the pump body 400, the circuit board 205 and the battery 500 are close to each other, so as to shorten the length of the wires between the pump body 400, the circuit board 205 and the battery 500, and the wiring is more convenient.

[0113] 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, which causes the size of the machine body 100 in the first direction to be too large, and the size of the machine body 100 in the second direction to be too small, and at this time, if the machine body 100 and the water tank 200 are arranged along the first direction, the oral irrigator 1 cannot be held; or the pump body 400, the circuit board 120 and the battery 500 are stacked along the second direction, which causes the size of the machine body 100 in the first direction to be too small, and the size of the machine body 100 in the second direction to be too large, and at this time, if the machine body 100 and the water tank 200 are arranged along the second direction, the oral irrigator 1 cannot be held. The above two ways will cause the size of the machine body 100 in the first direction and the size in the second direction to be inconsistent, and the comfort of holding the oral irrigator 1 by the user is low.

[0114] The oral irrigator 1 in the embodiment of the present application is arranged in a substantially "pin" shape, the size of the machine body 100 in the first direction and the size in the second direction are closer, the proportion of the machine body 100 is coordinated, the oral irrigator 1 is convenient for the user to hold, and the water tank 200 can be arranged along the length direction of the oral irrigator 1 with the machine body 100, and the water tank 200 can be arranged along the first direction or the second direction with the machine body 100, which will not cause the oral irrigator 1 to be unable to be held, and the layout flexibility of the oral irrigator 1 is high.

[0115] The oral irrigator 1 has the following at least one structure:

[0116] Firstly, the pump body 400 is connected with the circuit board 120, so that the pump body 400 and the circuit board 205 can be installed as a whole, the pump body 400 can be connected and fixed with the machine body 100, and the pump body 400 and the circuit board 205 do not need to be fixed with the machine body 100 respectively, which reduces the number of parts, reduces the weight of the oral irrigator 1 and reduces the cost.

[0117] Secondly, the pump body 400 is connected with the battery 500, so that the pump body 400 and the battery 500 can be installed as a whole, the pump body 400 can be connected and fixed with the machine body 100, and the pump body 400 and the battery 500 do not need to be fixed with the machine body 100 respectively, which reduces the number of parts, reduces the weight of the oral irrigator 1 and reduces the cost.

[0118] In addition, the pump body 400, the circuit board 205 and the battery 500 can be assembled into a whole, and then installed into the machine body 100, which simplifies the disassembly and assembly steps, improves the disassembly and assembly efficiency, and facilitates the later maintenance.

[0119] The third, the oral irrigator 1 further comprises a bracket, the bracket is mounted on at least one of the pump body 400 and the machine 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 with the pump body 400, the pump body 400 is connected with the machine body 100, or the bracket is connected with the machine body 100, or the bracket is connected with the pump body 400 and the machine body 100. In this way, the bracket will not displace in the machine body 100, and the relative position of the bracket and the machine 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 both 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 fixed in position by being directly connected to the machine body 100, without the need for machining the pump body 400, thereby reducing the machining difficulty of the pump body 400 and improving the production efficiency.

[0120] As shown in FIG. 4, the side of the pump body 400 opposite the battery 500 is provided with a water inlet 209 and a water scooping assembly 710, and the water scooping assembly 710 is in communication with the water inlet 209 and the water tank 200, respectively. 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, avoiding the influence of the battery 500 on the communication between the water inlet 209 and the water inlet channel 430, and preventing liquid from flowing to the battery 500 when the water inlet 209 leaks, thereby preventing the battery 500 from short-circuiting and improving the circuit safety of the oral irrigator 1.

[0121] As shown in FIGS. 4-6, the water scooping assembly 710 comprises a hose 420, an interface piece 430, and a filter piece 440. The hose 420 is connected with the pump body 400, the interface piece 430 is connected with the hose 420 and in communication with the water storage space 208, and the filter piece 440 is arranged on the interface piece 430 and used for filtering liquid flowing from the interface piece 430 to the hose 420.

[0122] In this way, the hose 420 can connect the interface piece 430 and the pump body 400, and the hose 420 can change its shape according to the arrangement inside the machine body 100, facilitating the communication between the interface piece 430 and the pump body 400 and improving the flexibility of the layout of the oral irrigator 1.

[0123] By setting the interface piece 430, the hardness of the interface piece 430 can be greater than the hardness of the hose 420, the interface piece 430 can change the flow direction of the liquid, and ensure that the liquid of the first interface 105 flows more smoothly to the hose 420. In addition, the interface piece 430 and the fuselage 100 can be fixedly connected, for example, the interface piece 430 and the fuselage 100 can be positioned and connected by a threaded fastener, to avoid relative displacement between the interface piece 430 and the fuselage 100, so that the relative position of the two ends of the hose 420 and the fuselage 100 is fixed, preventing the hose 420 from shaking in the fuselage 100.

[0124] In addition, the liquid flows through the filter 440 before flowing into the hose 420, the filter 440 removes impurities and the like in the liquid, improves the cleanliness of the liquid in the hose 420, and further improves the cleanliness of the liquid sprayed by the nozzle 300, making the oral irrigator 1 safer for cleaning teeth and helping to improve the oral health of the user.

[0125] The above-mentioned pump body 400 has a first connector, the first connector is provided with a water inlet 209, the hose 420 is sleeved on the first connector, and the first connector extends to the interface piece 430. That is, the diameter of the first connector is smaller than the diameter of the hose 420, so the flow rate of the liquid at the first connector is faster, and the speed of the liquid sprayed from the nozzle is faster.

[0126] Furthermore, the hose 420 is sleeved with the first connector 2211, so that 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.

[0127] When the first connector extends to the interface piece 430, the hose 420 can be shortened, thereby saving the material preparation cost of the hose 420, and at the same time, the first connector is arranged towards the interface piece 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.

[0128] As shown in FIG. 6, the above-mentioned interface piece 430 has a second connector 431, the hose 420 is sleeved on the second connector 431, and the second connector 431 extends to the pump body 400. That is, the diameter of the second connector 431 is also smaller than the diameter of the hose 420, so that when the pump body 400 works and the liquid in the water tank 200 is sucked to the interface piece 430, the flow rate of the liquid at the second connector 431 is faster because the diameter of the second connector 431 is smaller than the diameter of the hose 420, so as to facilitate the liquid to flow quickly into the hose 420.

[0129] Furthermore, the hose 420 is sleeved with the second connector 431, so that the connection between the hose 420 and the second connector 431 is more stable, thereby improving the stability of the connection between the hose 420 and the interface piece 430.

[0130] When the second joint 431 is arranged to extend towards the pump body 400, the hose 420 is shortened, thus saving the material preparation cost of the hose 420, and meanwhile, the second joint 431 is arranged towards the pump body 400, which can facilitate the connection of the hose 420 and the second joint 431, thereby improving the assembly efficiency of the hose 420 and the interface piece 430.

[0131] As shown in FIG. 6, the above-mentioned water scooping assembly 710 further comprises a compression piece 450, which can be elastically deformed, and the compression piece 450 can be made of soft rubber material such as rubber or silica gel. The interface piece 430 is provided with a receiving groove 432, the filter piece 440 is arranged in the receiving groove 432, and the compression piece 450 is arranged in the receiving groove 432. The filter piece 440 is clamped between the compression piece 450 and the bottom wall of the receiving groove 432.

[0132] That is, the filter piece 440 is clamped between the interface piece 430 and the compression piece 450 in the axial direction of the receiving groove 432, which avoids displacement of the filter piece 440 relative to the interface piece 430, and ensures that the liquid flowing into the hose 420 will pass through the filter piece 440, thereby further improving the cleanliness of the liquid in the hose 420.

[0133] Moreover, since the interface piece 430 is provided with the receiving groove 432 for accommodating the filter piece 440 and the compression piece 450, the relative positions of the compression piece 450 and the interface piece 430 can be fixed, thereby keeping the relative positions of the filter piece 440, the interface piece 430 and the compression piece 450 stable.

[0134] In addition, the inner wall of the machine body 100 is provided with a compression protrusion 104, and a part of the compression piece 450 is arranged between the end face of the compression protrusion 104 and the bottom wall of the receiving groove 432, and another part of the compression piece 450 is clamped between the outer peripheral surface of the compression protrusion 104 and the inner peripheral surface of the receiving groove 432.

[0135] That is, a part of the compression piece 450 can be compressed by the end of the compression protrusion 104 to tightly adhere to the filter piece 440, and this part can be elastically deformed to fill between the end of the compression protrusion 104 and the bottom wall of the receiving groove 432, which on the one hand can avoid movement of the filter piece 440 in the receiving groove 432, thereby ensuring the filtering effect of the filter piece 440, and on the other hand can prevent liquid from flowing out from between the end of the compression protrusion 104 and the bottom wall of the receiving groove 432, thereby reducing the probability of liquid leakage into the machine body 100.

[0136] Another part of the pressing member 450 can be pressed between the outer circumferential surface of the pressing protrusion 104 and the inner circumferential surface of the accommodating groove 432, can be elastically deformed to fill the space between the outer circumferential surface of the pressing protrusion 104 and the inner circumferential surface of the accommodating groove 432, can prevent liquid from leaking into the body 100 from the space between the outer circumferential surface of the pressing protrusion 104 and the inner circumferential surface of the accommodating groove 432, further reduces the probability of liquid leaking into the body 100, ensures that the liquid in the accommodating groove 432 flows to the hose 420 through the filter 440, and reduces the probability of short circuit of electrical components in the body 100.

[0137] In actual use, liquid is easy to stick 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, and 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 is easy to cause bacteria to grow inside the water tank 200, affecting the health and safety of the user

[0138] Therefore, the inner wall of the water tank 200 is provided with a hydrophobic layer 213. It can be understood that the inner wall of the water tank 200 can be provided with a hydrophobic layer 213 as a whole or partially. The hydrophobic layer 213 can include at least one of a hydrophobic film and a hydrophobic nano structure. The hydrophobic film can be attached or coated on the wall surface of the water tank 200, and the hydrophobic nano structure can be directly formed on the wall surface of the water tank 200 by processing, such as forming nano particles, nanowires or nanotubes on the wall surface of the water tank 200.

[0139] In this way, the embodiment provides the hydrophobic layer 213 on the inner wall of the water tank 200, so that the liquid originally adhered to the water tank 200 cannot adhere to the inner wall of the water tank 200, but can flow to the bottom of the water tank 200 along the inner wall 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 easy to stick to the liquid, and reduces the risk of bacteria growing inside the water tank 200 when the cleaning tool 1 is not used for a long time. In addition, the user does not need to specially take a paper towel or a towel after use to clean the inner wall of the water tank 200, and the convenience of cleaning the inner wall of the water tank 200 is improved.

[0140] For 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 stably when using the cleaning tool 1, and prevent the cleaning tool 1 from falling off the user's hand or the user's operation from being unstable due to the user's wet and slippery hand or the water tank 200 being too slippery. It can be understood that during the use of the cleaning tool 1, the liquid flushed during the flushing of the toilet will flow to the outer wall of the water tank 200, and based on the existence of the gap, the liquid will be easily retained in the gap, and the user will usually not be able to wipe off the liquid in the gap, which will cause bacteria to easily breed in the gap.

[0141] When the liquid sticks to the outer wall of the water tank 200, the user needs to take a paper towel or a towel and specially clean the outer wall of the water tank 200 after using the cleaning tool 1, otherwise the user's hand, clothes or bag will be wet.

[0142] Therefore, the outer wall of the water tank 200 is provided with a hydrophobic layer 213. In addition, the outer wall of the water tank 200 can be provided with a hydrophobic layer 213 as a whole or partially. The hydrophobic layer 213 can include at least one of a hydrophobic film and a hydrophobic nano structure. The hydrophobic film can be attached or coated on the wall surface of the water tank 200, and the hydrophobic nano structure can be directly formed on the wall surface of the water tank 200 by processing, such as forming nano particles, nano wires or nano tubes on the wall surface of the water tank 200.

[0143] The embodiment provides the hydrophobic layer 213 on the outer wall of the water tank 200, so that the liquid originally adhered to the outer wall of the water tank 200 cannot be attached to the outer wall, and cannot be attached to the gap in the outer wall, thereby reducing the risk of bacteria breeding on the outer wall of the water tank 200 and the gap. In addition, even if part of the liquid is attached to the outer wall and the gap in the outer wall, the user only needs to swing the water tank 200, and the liquid will fall off, which is very convenient to operate, and avoids the liquid from wetting the user's hand, clothes or bag.

[0144] Further, the structure of the above-mentioned oral irrigator 1 is at least one of:

[0145] The first kind, the fuselage 100 and the hydrophobic layer 213 are spaced apart, at this time the water tank 200 and the fuselage 100 can be non-actively connected, the non-active connection form referred to here is that the water tank 200 and the fuselage 100 do not move relative to each other, for example, they do not move, slide or rotate relative to each other, etc. It can be avoided that the fuselage 100 causes scratches or scratches the hydrophobic layer 213 provided on the outer wall of the water tank 200 or the hydrophobic layer 213 provided on the inner wall of the water tank 200 when the fuselage 100 moves relative to the water tank 200, causing the hydrophobic layer 213 to fail; 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 213 provided on the outer wall of the water tank 200 or the hydrophobic layer 213 provided on the inner wall of the water tank 200. In this way, it can be avoided that the fuselage 100 causes scratches or scratches the hydrophobic layer 213 provided on the outer wall of the water tank 200 or the hydrophobic layer 213 provided on the inner wall of the water tank 200 when the fuselage 100 slides relative to the water tank 200, causing the hydrophobic layer 213 to fail.

[0146] As shown in FIG. 2, the second kind, the water tank 200 is provided with a water inlet 209, the water inlet 209 is provided with an end cover 600, the end cover 600 is movably connected with the water tank 200, to open or close the water inlet 209, that is, when it is needed to inject liquid into the water tank 200, the water inlet 209 can be opened by operating the end cover 600, and after the injection is completed, the end cover 600 can be operated to close the water inlet 209, which is convenient to operate and can reduce the risk of liquid overflow when the water inlet 209 is closed. Exemplarily, the movable connection form of the end cover 600 and the water tank 200 can be sliding connection, plug-in connection or hinged connection, etc.

[0147] Moreover, the end cover 600 and the hydrophobic layer 213 are spaced apart, so that the end cover 600 can prevent scratches or scratches the hydrophobic layer 213 and cause the hydrophobic layer 213 to fail.

[0148] As shown in FIG. 2, the third kind, the water tank 200 is provided with a water inlet 209, the water inlet 209 is provided with an end cover 600, the end cover 600 is movably connected with the water tank 200, to open or close the water inlet 209, that is, when it is needed to inject liquid into the water tank 200, the water inlet 209 can be opened by operating the end cover 600, and after the injection is completed, the end cover 600 can be operated to close the water inlet 209, which is convenient to operate and can reduce the risk of liquid overflow when the water inlet 209 is closed. Exemplarily, the movable connection form of the end cover 600 and the water tank 200 can be sliding connection, plug-in connection or hinged connection, etc.

[0149] And, the part of the end cover 600 that extends into the water tank 200 (i.e. the plug-in section 610 and the pull-out nail 620 described below) is made of soft rubber. Thus, even if the part of the end cover 600 that extends into the water tank 200 comes into contact with the hydrophobic layer 213, the part of the end cover 600 that extends into the water tank 200 is less likely to scratch or dislodge the hydrophobic layer 213 due to the softness of the soft rubber, and the hydrophobic layer 213 can be better protected.

[0150] As shown in FIG. 7, in the fourth type, the water tank 200 is provided with a water suction pipe 207 that is in communication with the body 100. The provision of the water suction pipe 207 effectively reduces the amount of liquid remaining in the water tank 200 and is conducive to reducing the probability of leakage of the liquid during the transmission of the liquid from the water tank 200 to the pump body 400. Moreover, the provision of the water suction pipe 207 facilitates the docking operation of the pump body 400 and the water tank 200, making the docking more efficient and accurate.

[0151] Moreover, the water suction pipe 207 is spaced apart from the hydrophobic layer 213. Thus, the water suction pipe 207 is less likely to scratch or dislodge the hydrophobic layer 213, which can cause the hydrophobic layer 213 to fail.

[0152] As shown in FIG. 7, in the fifth type, the water tank 200 is provided with a water suction pipe 207 that is in communication with the body 100. The provision of the water suction pipe 207 effectively reduces the amount of liquid remaining in the water tank 200 and is conducive to reducing the probability of leakage of the liquid during the transmission of the liquid from the water tank 200 to the pump body 400. Moreover, the provision of the water suction pipe 207 facilitates the docking operation of the pump body 400 and the water tank 200, making the docking more efficient and accurate.

[0153] Moreover, the water suction pipe 207 is capable of deforming when it comes into contact with the hydrophobic layer 213. Thus, even if the water suction pipe 207 moves relative to the water tank 200 and comes into contact with the hydrophobic layer 213, the water suction pipe 207 is less likely to scratch or dislodge the hydrophobic layer 213 due to the softness of the soft tube 420.

[0154] As shown in FIG. 2, the oral irrigator 1 further includes a nozzle 300 and an end cover 600. The nozzle 300 is connected to the top end of the body 100, and the top end of the water tank 200 or the top end of the body 100 is provided with a water inlet 209 that is in communication with the water storage space 208.

[0155] That is to say, no matter whether the water inlet 209 is arranged on the machine body 100 or the water tank 200, the water inlet 209 is located at the top end of the whole oral irrigator 1 (except the nozzle 300), in this case, when the oral irrigator 1 is filled with water, the oral irrigator 1 still maintains a vertical state (i.e. the length direction of the oral irrigator 1 extends along the up-down direction), the state of the oral irrigator 1 when filled with water is consistent with the state of the oral irrigator 1 when used, and the oral irrigator 1 does not need to be flipped or rotated, so that the user does not need to excessively turn the wrist, and the oral irrigator 1 is more convenient to use.

[0156] In addition, the end cover 600 is flipable between the open state and the closed state relative to the water inlet 209, and in the case that the end cover 600 is switched from the closed state to the open state, the end cover 600 is flipped towards the nozzle 300. In the case that the end cover 600 is in the closed state, the water inlet 209 is capped, and in the case that the end cover 600 is in the open state, the end cover 600 abuts against the nozzle 300, the water inlet 209 is open, and the water storage space 208 is in communication with the atmosphere through the water inlet 209.

[0157] In this way, in the case that the end cover 600 is in the closed state, the water inlet 209 is capped, on the one hand, to prevent the liquid in the water tank 200 from leaking out of the water inlet 209, and on the other hand, to prevent external dirty impurities from entering the water tank 200, so as to ensure the cleanliness of the liquid in the water tank 200, and the oral irrigator 1 is safer for oral cleaning. In the case that the end cover 600 is in the open state, the end cover 600 abuts against the nozzle 300, the free end of the end cover 600 and the nozzle 300 are substantially at the same position, so that the water filling device avoids the nozzle 300 to some extent, and the hand and the nozzle 300 are less obstructed to the water filling device, the relative position between the oral irrigator 1 and the water filling device is more flexible, the oral irrigator 1 is more convenient to fill with water, and it is convenient for the user to fill water after the end cover 600 is opened.

[0158] As shown in FIG. 2, further, the end cover 600 is provided with a plug-in section 610 and a pull pin 620, the plug-in section 610 is inserted into the water inlet 209 and is sealed with the inner wall of the water inlet 209, and in the radial direction of the oral irrigator 1, the water inlet 209 and the nozzle 300 are provided with a through hole 621, and the pull pin 620 is inserted into the through hole 621, and the pull pin 620 is limited by the side wall of the through hole 621 along the axial direction of the through hole 621.

[0159] In the process that the end cover 600 is flipped from the closed state to the open state, the plug-in section 410 is gradually pulled out of the water inlet 209. In this way, the plug-in section 410 can seal the water inlet 209, on the one hand, to prevent the liquid in the water tank 200 from leaking out of the water inlet 209, and on the other hand, to prevent external dirty impurities from entering the water tank 200, so as to ensure the cleanliness of the liquid in the water tank 200, and the oral irrigator 1 is safer for oral cleaning.

[0160] When the end cover 600 is switched from the open state to the closed state, the plug-in part 410 is pulled out of the water inlet 209 and is flipped in the direction of the nozzle 300. During this process, the pull pin 620 gradually moves upward. When the end cover 600 abuts against the nozzle 300, the side wall of the pull pin 620 and the via hole 621 can abut against each other to prevent the pull pin 620 from being separated from the via 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 pull pin 620 and the water tank 200 and the machine body 100 is determined, the plug-in part 410 is more accurately inserted into the water inlet 209, and the switching of the end cover 600 between the open state and the closed state is more convenient.

[0161] Since the via hole 621 is located between the water inlet 209 and the nozzle 300, the size of the movement of the pull pin 620 is smaller than the size of the movement of the plug-in part 410, so that the pull pin 620 can be prevented from being separated from the via hole 621 when the end cover 600 is in the open state. When the end cover 600 is in the closed state, the size of the pull pin 620 in the length direction of the oral irrigator 1 can be greater than the size of the plug-in part 410, which can further prevent the pull pin 620 from being separated from the via hole 621 when the end cover 600 is in the open state.

[0162] As shown in FIGS. 1 and 3, the oral irrigator 1 further includes a clamping piece 310, a reset piece 320, and a disassembly button 330. The clamping piece 310 is movably arranged in the machine body 100. When the clamping piece 310 is in contact with the nozzle 300, the relative position of the nozzle 300 and the machine body 100 is limited. When the clamping piece 310 is separated from the nozzle 300, the nozzle 300 and the machine body 100 can be separated. The reset piece 320 is connected with the clamping piece 310 and the machine body 100, and is used to make the clamping piece 310 have a tendency to move close to the nozzle 300. The disassembly button 330 is arranged on the machine body 100 and connected with the clamping piece 310. At least a part of the disassembly button 330 is located outside the machine body 100. The disassembly button 330 is pressed to drive the clamping piece 310 to separate from the nozzle 300. The user can separate the nozzle 300 from the machine body 100 by pressing the disassembly button 330, so that the nozzle 300 and the machine body 100 are prevented from being separated accidentally, and the nozzle 300 is convenient to replace and the cleaning degree is higher.

[0163] The top of the machine body 100 is provided with a plug-in port 340 for plugging the nozzle 300. The plug-in port 340 is located at the center of the top of the machine body 100. In this way, the top of the machine body is stressed evenly, the plug-in port 340 is not easy to be damaged, and the connection between the nozzle 300 and the machine body 100 is stable.
