For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0045] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0046] See also Figure 1 The embodiment of the present application provides a water flosser 100, including a body 1, a water tank 2 and a nozzle 3. One end of the body 1 is connected to the water tank 2, and the other end is connected to the nozzle 3. A pressurizing member (not shown) is provided in the body 1. The pressurizing member is used to pressurize the water in the water tank 2 to form a high-pressure water flow, and guide the high-pressure water flow to the nozzle 3. The nozzle 3 is provided with a nozzle so that the high-pressure water flow can be ejected from the nozzle to achieve the function of cleaning teeth.

[0047] See also Figure 2 , for the convenience of description, Figure 2 In the figure, X represents the horizontal direction, and Y represents the longitudinal direction; the above-mentioned fuselage 1 includes a shell assembly 11 and a first clamping structure 12, the first clamping structure 12 can be movably connected to the shell assembly 11, the water tank 2 is provided with a first clamping groove 21, the shell assembly 11 at least partially extends into the water tank 2 and is detachably connected to the water tank 2, and the first clamping structure 12 is used to clamp with the first clamping groove 21.

[0048] In one embodiment, different from the prior art in which the body 1 and the water tank 2 are connected by sliding or fixed connection, the body 1 and the water tank 2 of the present application are connected in a detachable manner. In this way, the volume of the water tank 2 is fixed. When it is necessary to fill the water tank 2 with water, the user can remove the water tank 2 from the body 1 and take the water tank 2 away for filling with water. A water filling port is provided on the top of the water tank 2 to facilitate the user to fill water into the water tank 2. This method effectively prevents water from spilling to the outside of the water tank 2 and wetting the surrounding environment.

[0049] Specifically, the first clamping structure 12 can move relative to the shell assembly 11 to selectively engage or disengage with the first clamping slot 21. When the first clamping structure 12 is engaged with the first clamping slot 21, the water tank 2 and the shell assembly 11 are relatively fixed. When the first clamping structure 12 is pressed, the first clamping structure 12 and the first clamping slot 21 are relatively separated to separate the water tank 2 and the shell assembly 11.

[0050] In one embodiment, the present application realizes a detachable connection between the water tank 2 and the shell assembly 11 through a first clip structure 12. The difference from the pull-out water tank in the prior art is that: the water tank 2 will not move relative to the shell assembly 11, and the water tank 2 and the shell assembly 11 are relatively fixed. Only by pressing the first clip structure 12 can the first clip structure 12 move relative to the shell assembly 11, and at the same time, the first clip structure 12 also moves relative to the water tank 2, thereby separating the first clip structure 12 from the first slot 21, thereby realizing the separation of the water tank 2 from the shell assembly 11.

[0051] In actual application, when the shell assembly 11 extends into the water tank 2, the first clamping structure 12 is clamped with the first clamping groove 21 to realize the fixed connection between the water tank 2 and the fuselage 1, so that the fuselage 1 can guide the water in the water tank 2 to the nozzle 3, and form a high-pressure water flow to be sprayed out from the nozzle 3; when it is necessary to fill the water tank 2 with water, since the first clamping structure 12 is movably connected with the shell assembly 11, that is, the first clamping structure 12 can move linearly or rotate circumferentially relative to the shell assembly 11, in this embodiment, a connection method in which the first clamping structure 12 can move linearly relative to the shell assembly 11 is adopted. The user presses the first clamping structure 12 to push the first clamping structure 12 to move. Specifically, the user pushes the first clamping structure 12 away from the first clamping groove 21 along the transverse direction X until the first clamping structure 12 is separated from the first clamping groove 21, and then the shell assembly 11 is pulled out of the water tank 2 to realize the separation of the fuselage 1 and the water tank 2, so that the water tank 2 can be filled with water alone. Compared with the prior art, the body 1 and the water tank 2 of the present application are connected in a detachable manner. When water filling is needed, the water tank 2 can be removed from the body 1 and used alone to fill water, which is easy to operate and effectively avoids the situation where water splashes due to misalignment of the water inlet during water filling, while improving the water filling efficiency.

[0052] See also Figure 3 The first snap-fitting structure 12 includes a first snap-fitting structure 121 and an elastic member 122. The shell assembly 11 is provided with a slide groove 112. ...

[0053] In one embodiment, the first clip structure 12 is elastically connected to the shell assembly 11. Specifically, the first clip structure 12 includes a first clip 121 and an elastic member 122. The first clip 121 is slidingly connected to the shell assembly 11, and the elastic member 122 is respectively abutted between the first clip 121 and the shell assembly 11. In actual application, the user presses the first buckle 121 and pushes the first buckle 121 to move away from the first slot 21, so that the first buckle 121 is separated from the first slot 21, and at the same time, the first buckle 121 retracts into the shell assembly 11 and squeezes the elastic member 122. At this time, the user can separate the water tank 2 from the fuselage 1; when the water tank 2 needs to be connected to the fuselage 1, the user presses the first buckle 121 and extends the shell assembly 11 into the water tank 2. When the positions of the first buckle 121 and the first slot 21 are relative, the user lets go, and through the restoring force of the elastic member 122, the first buckle 121 is pushed toward the first slot 21, so that the first buckle 121 is engaged with the first slot 21, thereby realizing the fixed connection between the water tank 2 and the fuselage 1. This method has a simple structure, saves costs, and is relatively convenient to operate.

[0054] See again Figure 3 The body 1 includes a limit member 13, which is connected to the shell assembly 11 and is spaced apart from the first clamping structure 12; wherein, when the first clamping structure 12 moves in a direction away from the first clamping slot 21, the limit member 13 is used to abut against the first clamping structure 12 to limit the movement of the first clamping structure 12.

[0055] In actual application, in order to prevent the user from pressing the first buckle 121 too hard, causing the first buckle 121 to enter the shell assembly 11 to a greater depth, the present application provides a limit member 13, and the limit member 13 is arranged behind the first buckle 121 in the direction away from the first slot 21. When the first buckle 121 moves in the direction away from the first slot 21, the first buckle 121 moves a certain distance and then abuts against the limit member 13 at the rear. The limit member 13 prevents the first buckle 121 from continuing to move, thereby preventing the first buckle 121 from moving too far, causing the elastic member 122 to be squeezed beyond the elastic limit, causing the elastic member 122 to lose its restoring elasticity and fail to reset the first buckle 121, thereby affecting the connection between the water tank 2 and the body 1.

[0056] See also Figure 3The shell assembly 11 is further provided with a second buckle 115 , and the water tank 2 is provided with a second slot 22 ; wherein, when the shell assembly 11 is at least partially extended into the water tank 2 , the second buckle 115 is engaged with the second slot 22 .

[0057] Specifically, the second buckle 115 is arranged on a side of the shell assembly 11 away from the first buckle 121. Preferably, the first buckle 121 and the second buckle 115 can be respectively arranged on opposite sides of the shell assembly 11. When the shell assembly 11 extends into the water tank 2, the first buckle 121 is engaged with the first slot 21, and the second buckle 115 is engaged with the second slot 22 to achieve a fixed connection between the fuselage 1 and the water tank 2. By setting the second buckle 115, the connection between the water tank 2 and the fuselage 1 is more stable.

[0058] In one embodiment, the second buckle 115 and the housing assembly 11 can be fixedly connected or integrally formed, which has a simple structure and saves design space. In other embodiments, the second buckle 115 can also be connected in other ways, which is not limited in this application.

[0059] See also Figure 4 The above-mentioned first buckle 121 includes a button portion 1211 and a hook portion 1212 that are connected to each other. The button portion 1211 is slidably connected to the slide groove 112, and the hook portion 1212 is used to engage with the first slot 21; wherein, in the extension direction of the slide groove 112 and along the direction approaching the shell assembly 11, the gap between the button portion 1211 and the slot wall of the slide groove 112 gradually decreases.

[0060] The button portion 1211 is mainly used for being pressed by the user. Preferably, the button portion 1211 at least partially extends out of the shell assembly 11 to facilitate the user to press it. The user presses the button portion 1211 to make the button portion 1211 slide in the slide groove 112, and the button portion 1211 drives the hook portion 1212 to move, thereby separating the hook portion 1212 from the first slot 21.

[0061] In one embodiment, Figure 4 As shown in the figure, the gap between the button portion 1211 and the wall of the slide groove 112 is L1, and L1 gradually decreases in the extension direction of the slide groove 112 along the direction close to the shell assembly 11. This arrangement can prevent the water in the water tank 2 from seeping out through the gap between the button portion 1211 and the slide groove 112, and at the same time does not affect the free sliding of the button portion 1211 in the slide groove 112, thereby enhancing the sealing of the connection between the fuselage 1 and the water tank 2.

[0062] See again Figure 4The first buckle 121 also includes a blocking portion 1213, which is circumferentially connected to the circumferential side of the button portion 1211 and abuts against the inner wall of the housing assembly 11 at the slide groove 112. The blocking portion 1213 is used to block the gap between the slide groove 112 and the button portion 1211.

[0063] In actual application, even if the gap L1 between the button part 1211 and the wall of the slide groove 112 is small, there is still a probability that water will seep out of this gap. In order to further strengthen the sealing between the fuselage 1 and the water tank 2, the present application provides a sealing part 1213, which is circumferentially connected to the circumference of the button part 1211. When the hook part 1212 is engaged with the first slot 21, the button part 1211 is located in the slide groove 112, and the sealing part 1213 abuts against the inner wall of the shell assembly 11 at the slide groove 112. In this way, the sealing part 1213 blocks the gap between the button part 1211 and the slide groove 112, thereby reducing the probability of water seeping out of this gap.

[0064] See also Figure 5 The body 1 also includes an interface device 15 and a cover plug 16. The shell assembly 11 is provided with a first installation space and an opening connected to the first installation space. The interface device 15 is assembled in the first installation space. The cover plug 16 is used to cover the opening to block the interface device 15.

[0065] It should be noted that the oral irrigator 100 is an electric device having a charging element and a charging port. The charging element provides electrical energy to the oral irrigator 100 , and during normal use, the charging element needs to be charged regularly through the charging port.

[0066] Therefore, the above-mentioned interface device 15 can be used as a charging element for charging the oral irrigator 100. The interface device 15 is assembled in the first installation space, and the opening on the shell assembly 11 is set as a charging port. When the oral irrigator 100 is used, the water sprayed from the nozzle 3 will splash onto the body 1 and flow along the body 1. In order to prevent external water from flowing into the first installation space through the opening and contaminating the interface device 15, the present application provides a sealing plug 16, which is covered on the opening and seals the opening to prevent water from entering the interface device 15.

[0067] See again Figure 5 A second installation space is also opened inside the shell assembly 11, and the first clamping structure 12 is assembled in the second installation space. The cover plug 16 includes a cover portion 161 and a lifting portion 162, and the lifting portion 162 is connected to a side of the cover portion 161 close to the shell assembly 11; wherein the lifting portion 162 is inserted into the shell assembly 11 to separate the first installation space and the second installation space, and the cover portion 161 is used to cover the opening.

[0068] Since the fuselage 1 is connected to the water tank 2, the interior of the fuselage 1 is in a connected state with the water tank 2, so the water in the water tank 2 can flow from the interior of the fuselage 1 into the first installation space, which will also cause the water flow to contaminate the interface device 15. Based on this, the cover plug 16 is provided with a cover portion 161 and a lifting portion 162. The cover portion 161 is used to cover the opening to prevent the water flow outside the fuselage 1 from flowing into the first installation space; the lifting portion 162 extends into the shell assembly 11 and separates the first installation space from the second installation space. It can be understood that the first clamping structure 12 needs to be clamped with the water tank 2, so compared with the first installation space, the second installation space is closer to the water tank 2, that is, the water in the water tank 2 is easier to enter the second installation space. Through the separation effect of the lifting portion 162, the lifting portion 162 prevents the water in the second installation space from entering the first installation space, thereby playing a role in protecting the interface device 15.

[0069] See also Figure 6 A covering groove 111 is provided on the outer surface of the shell assembly 11, and the covering groove 111 surrounds the opening. The covering portion 161 is accommodated in the covering groove 111, and a gap is provided between the covering portion 161 and the groove wall of the covering groove 111 to form a first operating space 1111, and the first operating space 1111 is used for the user to insert his hand.

[0070] In order to facilitate the cover part 161 to cover the opening, the housing assembly 11 is provided with a cover groove 111, which surrounds the opening and provides a space for the cover part 161 to be installed in the cover groove 111 and cover the opening. At the same time, a gap is left between the cover part 161 and the groove wall of the cover groove 111 to form a first operating space 1111. When the oral irrigator 100 needs to be charged, the first operating space 1111 provides a certain amount of accommodation space. The user can put his finger into this space and then apply force to take the cover part 161 out of the cover groove 111. The first operating space 1111 provides a space for the user to apply force, so that the user can smoothly and quickly take the cover part 161 out of the cover groove 111, thereby improving the charging convenience of the oral irrigator 100.

[0071] See also Figure 6 and Figure 7 The capping plug 16 further includes a limiting portion 163 , which is connected to the lifting portion 162 . The limiting portion 163 is used to abut against the shell assembly 11 to limit the lifting portion 162 from separating from the shell assembly 11 .

[0072] In actual application, the oral irrigator 100 needs to be charged regularly, so the cover portion 161 will be frequently taken out from the cover groove 111. When the cover portion 161 is taken out from the cover groove 111, the cover portion 161 will drive the lifting portion 162 to move away from the shell assembly 11. In order to prevent the lifting portion 162 from detaching from the shell assembly 11, thereby causing the lifting portion 162 to be unable to separate the first installation space and the second installation space, the present application provides a limiting portion 163 on the lifting portion 162. When the cover portion 161 drives the lifting portion 162 to move to a certain distance, the limiting portion 163 abuts against the shell assembly 11, preventing the lifting portion 162 from continuing to move. At this time, the cover portion 161 leaves the cover groove 111 to facilitate charging of the oral irrigator 100. At the same time, the lifting portion 162 still serves to separate the first installation space and the second installation space to protect the interface device 15.

[0073] See again Figure 6 The cover portion 161 includes a third top surface 164 and a third bottom surface 165 relative to each other. When the cover portion 161 is accommodated in the cover groove 111, the third top surface 164 does not protrude from the outer surface of the shell assembly 11, and the third bottom surface 165 contacts the bottom of the cover groove 111 to cover the opening. In this way, the cover portion 161 is accommodated in the cover groove 111, and the outer surface does not protrude from the cover groove 111, which can prevent the user from accidentally touching the cover portion 161 and make the overall outer surface of the oral irrigator 100 smooth and smooth, thereby increasing the aesthetics of the oral irrigator 100.

[0074] Among them, the edge of the third bottom surface 165 is at least partially inclined in the direction close to the third top surface 164 to form a third inclined surface 166, and a second operating space 1112 is formed between the third inclined surface 166 and the bottom of the cover groove 111, and the second operating space 1112 is connected to the first operating space 1111. Specifically, in addition to the gap between the cover portion 161 and the groove wall of the cover groove 111 to form the first operating space 1111, a gap is also left between the cover portion 161 and the groove bottom of the cover groove 111 to form the second operating space 1112. The first operating space 1111 and the second operating space 1112 can be inserted by the user's fingers, and the second operating space 1112 is convenient for the user's fingers to apply force to take the cover portion 161 out of the cover groove 111, further improving the convenience of taking out the cover portion 161.

[0075] See also Figure 8The hook portion 1212 has a first top surface 1214 and a first bottom surface 1215 opposite to each other. In the concave direction of the first slot 21, at least a portion of the first bottom surface 1215 extends obliquely toward the direction close to the first top surface 1214 to form a first inclined surface 1216. The first slot 21 has a first slot wall 212 and an opposite first slot top 211 and a first slot bottom 213. The first slot wall 212 is connected to the first slot top 211 and the first slot bottom 213, respectively. The first slot bottom 213 extends obliquely toward the direction away from the first slot top 211.

[0076] Among them, when the hook portion 1212 is engaged with the first slot 21, the first top surface 1214 faces the first slot top 211, the first inclined surface 1216 faces the first slot bottom 213, the angle between the first inclined surface 1216 and the lateral direction X of the shell component 11 is α1 degrees, and the angle between the first slot bottom 213 and the lateral direction X of the shell component 11 is α2 degrees, α1-α2≤5.

[0077] Specifically, when the first buckle 121 is engaged with the first slot 21, the first top surface 1214 abuts against the first slot top 211 to prevent the first buckle 121 from separating from the first slot 21. At this time, the first inclined surface 1216 and the first slot bottom 213 have similar inclination angles relative to the same plane, and the difference in inclination angles between the two is within 5°, that is, the first inclined surface 1216 and the first slot bottom 213 are approximately parallel. In this way, when the first buckle 121 moves toward the first slot 21, the user cannot observe the position of the first buckle 121 relative to the first slot 21 during this process, and the first inclined surface 1216 and the first slot bottom 213 with similar inclination angles can play a guiding role, which is beneficial for the user to locate the position of the first buckle 121 in the blind field and facilitates the engagement of the first buckle 121 and the first slot 21.

[0078] Similarly, see Fig. 9 and Fig.10 The second buckle 115 has a second top surface 1151 and a second bottom surface 1152 opposite to each other. In the concave direction of the second slot 22, the second bottom surface 1152 at least partially extends obliquely toward the direction close to the second top surface 1151 to form a second inclined surface 1153. The second slot 22 has a second slot wall 222 and a second slot top 221 and a second slot bottom 223 opposite to each other. The second slot wall 222 is connected to the second slot top 221 and the second slot bottom 223 respectively. The second slot bottom 223 extends obliquely toward the direction away from the second slot top 221.

[0079] Among them, when the second buckle 115 is engaged with the second slot 22, the second top surface 1151 faces the second slot top 221, the second inclined surface 1153 faces the second slot bottom 223, the angle between the second inclined surface 1153 and the lateral direction X of the shell assembly 11 is β1 degrees, and the angle between the second slot bottom 223 and the lateral direction X of the shell assembly 11 is β2 degrees, β1-β2≤5.

[0080] In one embodiment, similar to the first buckle 121 and the first slot 21, the second inclined surface 1153 is approximately parallel to the second slot bottom 223. During the engagement process between the second buckle 115 and the second slot 22, the second inclined surface 1153 and the second slot bottom 223 having similar inclination angles play a guiding role, which is helpful for the user to locate the position of the second buckle 115 in his / her blind field and facilitates the engagement of the second buckle 115 and the second slot 22.

[0081] It is understandable that, in some other embodiments, the first buckle 121 can also be a first top surface 1214 that extends obliquely toward the direction close to the first bottom surface 1215 to form a first inclined surface 1216, and the first groove top 211 extends obliquely toward the direction away from the first groove bottom 213. At this time, the first inclined surface 1216 and the first groove top 211 play a guiding and matching role; the first buckle 121 can also be formed by other methods to form the first inclined surface 1216, and the inclined surface of the first slot 21 is opposite to the first inclined surface 1216. Similarly, the second buckle 115 can also be formed by other methods to form the second inclined surface 1153, and the inclined surface of the second slot 22 is opposite to the second inclined surface 1153. The present application does not limit this.

[0082] See again Fig. 9 The fuselage 1 further includes a sealing member 14. A sealing groove 113 is formed at one end of the shell assembly 11 extending into the water tank 2. The sealing member 14 is disposed in the sealing groove 113. The sealing member 14 abuts against the water tank 2 and the shell assembly 11 respectively.

[0083] The sealing groove 113 is arranged on the shell assembly 11, and the sealing member 14 is assembled in the sealing groove 113. When the shell assembly 11 is extended into the water tank 2, the sealing member 14 abuts against the inner wall of the water tank 2 to seal the gap between the shell assembly 11 and the inner wall of the water tank 2 to prevent water from leaking out, thereby improving the sealing performance of the oral irrigator 100.

[0084] Specifically, the distance between the sealing member 14 and the first clamping structure 12 is greater than 1 mm, and along the length direction of the housing assembly 11 , the distance between the bottom plane of the housing assembly 11 and the sealing member 14 is greater than 1 mm.

[0085] In one embodiment, when the shell assembly 11 is snapped together with the water tank 2, the seal 14 is closer to the water tank 2 relative to the position of the first snap-fit ​​structure 12 and the second snap 115. At the same time, the distance between the seal 14 and the first snap-fit ​​structure 12 or the second snap 115 can be greater than 1 mm, effectively avoiding water seepage at the snap-fitting portion of the shell assembly 11 and the water tank 2; and the length of the seal 14 from the bottom plane of the shell assembly 11 also needs to be limited, and this length can be greater than 1 mm to avoid the water in the water tank 2 being immersed in the seal 14 and affecting the sealing effect.

[0086] It is understandable that the distance between the seal 14 and the first clamping structure 12 can be set to other values. Similarly, the distance between the seal 14 and the bottom plane of the housing assembly 11 can also be set to other values, and the present application does not limit this.

[0087] See again Fig. 9 The shell assembly 11 is provided with a step portion 114. When the shell assembly 11 is at least partially extended into the water tank 2, the step portion 114 is used to abut against the end of the water tank 2; when the shell assembly 11 is extended into the water tank 2 and is engaged with the water tank 2, the step portion 114 abuts against the water tank 2 to limit the downward movement of the shell assembly 11 along its longitudinal direction Y. At the same time, combined with the abutment between the first top surface 1214 of the first buckle 121 and the first slot 21, and the abutment between the second top surface 1151 of the second buckle 115 and the second slot 22, the upward movement of the shell assembly 11 along its longitudinal direction Y is limited. Therefore, the step portion 114 and the buckle jointly limit the movement of the shell assembly 11 relative to the water tank 2, thereby making the connection between the shell assembly 11 and the water tank 2 more firmly and without shaking, thereby achieving a relatively fixed connection between the water tank 2 and the shell assembly 11.

[0088] In addition, the contact between the step portion 114 and the water tank 2 supports the body 1, thereby preventing the weight of the body 1 from being concentrated on the connecting portion between the shell assembly 11 and the water tank 2, thereby causing the connecting portion to be deformed due to force, affecting the normal service life of the oral irrigator 100.

[0089] More specifically, along the length direction of the shell assembly 11, the distance between the bottom plane of the shell assembly 11 and the step portion 114 is L mm, and L ≥ 7. That is, the length of the shell assembly 11 extending into the water tank 2 is greater than 7 mm, which ensures the connection stability between the water tank 2 and the shell assembly 11. It can be understood that the longer the length of the shell assembly 11 extending into the water tank 2, the more stable the connection between the shell assembly 11 and the water tank 2.

[0090] In some other embodiments, the length of the shell assembly 11 extending into the water tank 2 may also be other values, which is not limited in the present application.

[0091] Different from the prior art, the embodiment of the present application provides a water flosser 100, including a body 1 and a water tank 2, the body 1 including a shell assembly 11 and a first clamping structure 12, the first clamping structure 12 can be movably connected to the shell assembly 11, the water tank 2 is provided with a first clamping slot 21, the shell assembly 11 at least partially extends into the water tank 2 and is detachably connected to the water tank 2, and the first clamping structure 12 is used to clamp with the first clamping slot 21, the first clamping structure 12 can move relative to the shell assembly 11 to selectively clamp with or separate from the first clamping slot 21, when the first clamping structure 12 is clamped with the first clamping slot 21, the water tank 2 and the shell assembly 11 are relatively fixed, when the first clamping structure 12 is pressed, the first clamping structure 12 and the first clamping slot 21 are relatively separated to separate the water tank 2 and the shell assembly 11. Compared with the prior art, the body 1 and the water tank 2 of the present application are connected in a detachable manner. When water filling is needed, the water tank 2 can be removed from the body 1 and used alone to fill water, which is easy to operate and effectively avoids the situation where water splashes due to misalignment of the water inlet during water filling, while improving the water filling efficiency.

[0092] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
