Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0069] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense.

[0070] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0071] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0072] See also Figure 1 and Figure 2 The water pump assembly 100 includes: a water pump fixing bracket 1 and a water pump 2, wherein the water pump fixing bracket 1 includes a main frame 11, a water pump limiting structure 12 and a snap-fit ​​member 13, the water pump limiting structure 12 is arranged on the main frame 11 and together with the main frame 11 forms a water pump limiting space 10, the snap-fit ​​member 13 is arranged on the main frame 11, the water pump 2 is accommodated in the water pump limiting space 10, and the snap-fit ​​member 13 is used to snap-fit ​​with the water pump 2 to fix the water pump 2 in the water pump limiting space 10.

[0073] In the present embodiment, since the water pump limiting structure 12 is arranged on the main frame 11 and together with the main frame 11 forms the water pump limiting space 10, when it is necessary to fix the water pump 2 to the water pump fixing bracket 1, first, the water pump 2 can be placed in the water pump limiting space 10. After the water pump 2 is placed in the water pump limiting space 10, since the main frame 11 is provided with a fastener 13, the fastener 13 can be fastened to the water pump 2. When the fastener 13 is fastened to the water pump 2, under the dual action of the fastener 13 and the water pump limiting structure 12, the purpose of fixing the water pump 2 in the water pump limiting space 10 can be achieved, and then the purpose of fixing the water pump 2 to the water pump fixing bracket 1 can be achieved.

[0074] It can be seen that when the water pump 2 needs to be fixed to the water pump fixing bracket 1, the water pump 2 is first placed in the water pump limiting space 10, and then the fastener 13 is snapped into engagement with the water pump 2. The purpose of fixing the water pump 2 to the water pump fixing bracket 1 can be achieved by snapping. Compared with the method in the related art that requires locking screws to fix the water pump 2 to the water pump fixing bracket 1, the steps of fixing the water pump 2 to the water pump fixing bracket 1 can be simplified, making it convenient and quick to fix the water pump 2 to the water pump fixing bracket 1.

[0075] It should be noted that in order to better limit the water pump 2, the shape of the above-mentioned water pump limiting space 10 can be the same as the outer contour of the water pump 2. Of course, based on different application scenarios, the shape of the above-mentioned water pump limiting space 10 can also be different from the outer contour of the water pump 2. It only needs to be able to place the water pump 2. This embodiment does not limit the shape of the water pump limiting space 10.

[0076] The water pump assembly 100 can be applied to a personal care flushing device 200, which can be a nasal irrigator or a dental irrigator, etc. This embodiment makes a limitation on this.

[0077] In order to allow the water pump 2 to be stably limited in the water pump limit space 10, in some embodiments, see Figure 1 and Figure 2 , the first end 21 of the water pump 2 abuts against the main frame 11, and the peripheral wall of the water pump 2 abuts against the water pump limiting structure 12. In this way, the first end 21 and the peripheral wall of the water pump 2 can be limited by the main frame 11 and the water pump limiting structure 12 respectively, so that the water pump 2 can be limited from at least two directions, and then the water pump 2 can be stably limited in the water pump limiting space 10.

[0078] Of course, in other embodiments, the first end 21 of the water pump 2 may be abutted against the water pump limiting structure 12, and the peripheral wall of the water pump 2 may be abutted against the main frame 11. It is only necessary to enable the water pump 2 to be stably limited in the water pump limiting space 10, and this embodiment does not limit this.

[0079] It should be noted that the abutment between the first end 21 of the water pump 2 and the main frame 11 can be understood in a broad sense. Specifically, the first end 21 of the water pump 2 can abut the main frame 11 directly or indirectly. When the first end 21 of the water pump 2 abuts the main frame 11 indirectly, a vibration damper can be provided between the first end 21 of the water pump 2 and the main frame 11, and the first end 21 of the water pump 2 can abut the main frame 11 through the vibration damper. By providing a vibration damper between the first end 21 of the water pump 2 and the main frame 11, the effect of the vibration of the water pump 2 on the water pump fixing bracket 1 can be reduced. Based on this, when the water pump assembly 100 is applied to the personal care flushing device 200, the vibration of the entire personal care flushing device 200 can be reduced, so that the user experience of the personal care flushing device 200 becomes better.

[0080] In order to facilitate the placement of the water pump 2 in the water pump limiting space 10, in some embodiments, see Figure 2 and Figure 3 The water pump limiting space 10 has an opening 101 , and the opening 101 is used for the water pump 2 to be pushed into the water pump limiting space 10 through the opening 101 .

[0081] By setting the opening 101, when the water pump 2 needs to be placed in the water pump limiting space 10, the water pump 2 only needs to be placed in the opening 101, and then the water pump 2 is pushed, and the water pump 2 can pass through the opening 101 and slide into the water pump limiting space 10, which is very convenient and quick.

[0082] The shape of the opening 101 can be any possible shape, as long as it is convenient to place the water pump 2 in the water pump limiting space 10 through the opening 101 . The shape of the opening 101 is not limited in this embodiment.

[0083] In some embodiments, see Figure 1 Figure 2 and Figure 3 , the opening 101 and the first end 21 are along the first direction ( Figure 3 The opening 101 is used to push the water pump 2 into the water pump limiting space 10 through the opening 101 along the first direction.

[0084] Since the opening 101 is opposite to the first end 21 along the first direction, during the process of pushing the water pump 2 along the first direction through the opening 101, as the water pump 2 is continuously pushed along the first direction, the first end 21 can just abut against the main frame 11. When the first end 21 abuts against the main frame 11, the water pump 2 will not be able to continue to move forward along the first direction due to the blocking effect of the main frame 11. At this time, it can be considered that the water pump 2 has been installed in place, which makes it concrete whether the water pump 2 is installed in place, thereby facilitating the installation accuracy of the water pump 2.

[0085] In some embodiments, see Figure 1 and Figure 2 The water pump limiting structure 12 includes: a first water pump limiting member 121 and a second water pump limiting member 122, wherein the first water pump limiting member 121 is arranged on the main frame 11, and the second water pump limiting member 122 is arranged on the main frame 11 and is spaced apart from the first water pump limiting member 121, and the peripheral wall of the water pump 2 is respectively in contact with the first water pump limiting member 121 and the second water pump limiting member 122.

[0086] Since the second water pump limiting member 122 is spaced apart from the first water pump limiting member 121, the second water pump limiting member 122 and the first water pump limiting member 121 are disconnected from each other and have a gap therebetween. When there is a gap between the second water pump limiting member 122 and the first water pump limiting member 121, since the peripheral wall of the water pump 2 is respectively in contact with the first water pump limiting member 121 and the second water pump limiting member 122, at least part of the peripheral wall of the water pump 2 can be exposed through the gap between the first water pump limiting member 121 and the second water pump limiting member 122. In this way, on the one hand, the contact area with the peripheral wall of the water pump 2 can be reduced as much as possible while ensuring that the water pump 2 can be limited by the second water pump limiting member 122 and the first water pump limiting member 121, thereby reducing the amount of vibration transmitted by the water pump 2 to the water pump fixing bracket 1, and on the other hand, it is convenient for the mold to be demolded during injection molding, and on the other hand, it can also reduce the material used during injection molding.

[0087] In some embodiments, see Figure 2The first water pump stopper 121 has a first arc surface 1211 , and the first arc surface 1211 matches the peripheral wall of the water pump 2 and is used to abut against the peripheral wall of the water pump 2 .

[0088] Since the first curved surface 1211 matches the peripheral wall of the water pump 2 , when the peripheral wall of the water pump 2 abuts against the first curved surface 1211 , the first curved surface 1211 can better limit the water pump 2 , so that the water pump 2 can be placed more stably in the water pump limiting space 10 .

[0089] Of course, the first water pump stopper 121 may also have abutting surfaces of other shapes, as long as the shape of the abutting surface can match the peripheral wall of the water pump 2, and this embodiment does not limit this.

[0090] In some embodiments, see Figure 1 and Figure 2 The second water pump limiting member 122 is a water pump limiting rib, and the first limiting surface (not shown in the figure) of the water pump limiting rib abuts against the peripheral wall of the water pump 2. The first limiting surface is the side of the water pump limiting rib opposite to the first water pump limiting member 121. Specifically, when the first water pump limiting member 121 has a first arc surface 1211, the first limiting surface is the side of the water pump limiting rib opposite to the first arc surface 1211. Since the water pump limiting rib has a simple structure, uses less material during injection molding, and is easy to process, the manufacturing cost of the second water pump limiting member 122 can be reduced while reducing the difficulty of processing the second water pump limiting member 122.

[0091] The shape of the water pump limiting ribs may be a straight line or an S shape, etc. This embodiment does not limit the shape of the water pump limiting ribs.

[0092] Of course, in other embodiments, the second water pump stopper 122 may also be other possible structures, and this embodiment does not limit the second water pump stopper 122 .

[0093] Further, in order to make the water pump 2 more stably placed in the water pump limiting space 10, in some embodiments, see Figure 1 , Figure 2 and Figure 3 The water pump limiting structure 12 further includes: a third water pump limiting member 123, which is disposed on the main frame 11 and is located on a side of the second water pump limiting member 122 away from the first end 21 ( Figure 2 The third water pump limiting member 123 has a second limiting surface 1231 opposite to the peripheral wall of the water pump 2.

[0094] Since the third water pump limiting member 123 is located on the side of the second water pump limiting member 122 away from the first end 21, and since the second limiting surface 1231 of the third water pump limiting member 123 is opposite to the peripheral wall of the water pump 2, the second limiting surface 1231 can limit the water pump 2, so that the water pump 2 can be placed more stably in the water pump limiting space 10.

[0095] In some embodiments, see Figure 2 and Figure 3 The second limiting surface 1231 is a second arc surface, and the direction of the second arc surface is opposite to the direction of the first arc surface 1211.

[0096] Since the direction of the second curved surface is opposite to that of the first curved surface 1211, the second curved surface and the first curved surface 1211 can respectively limit the surrounding wall of the water pump 2 from both sides of the water pump 2. On the one hand, the water pump 2 can be more stably placed in the water pump limiting space 10. On the other hand, the third water pump limiting component 123 and the first water pump limiting component 121 can wrap the surrounding wall of the water pump 2 from different directions to protect the water pump 2 and prevent the water pump 2 from being disturbed by the external environment.

[0097] In some embodiments, see Figure 3 and Figure 4 , there is a gap J between the second curved surface and the peripheral wall of the water pump 2. By providing the gap J between the second curved surface and the peripheral wall of the water pump 2, on the one hand, it is possible to prevent the peripheral wall of the water pump 2 from directly abutting against the second curved surface and transmitting the vibration of the water pump 2 to the third water pump stopper 123, and on the other hand, the second curved surface guides the water pump 2 during the process of pushing the water pump 2 into the water pump stopper space 10 through the opening 101, so that the water pump 2 can be pushed into the water pump stopper space 10 more smoothly through the opening 101.

[0098] In order to ensure that the second arc surface can limit the water pump 2 and reduce the possibility of the water pump 2 transmitting its own vibration to the second arc surface as much as possible, in some embodiments, a vibration damping member is provided in the gap J. By providing the vibration damping member, on the one hand, the water pump 2 can be in contact with the second arc surface through the vibration damping member, so that the second arc surface can limit the water pump 2, and on the other hand, it can also reduce the possibility of the water pump 2 transmitting its own vibration to the second arc surface.

[0099] The vibration damper may be a foam vibration damper or a rubber vibration damper, etc., and this embodiment does not limit the vibration damper.

[0100] In some embodiments, see Figure 2The main frame 11 includes: an end abutment member 111, a first reinforcement member 112 and a second reinforcement member 113, wherein the first end 21 of the water pump 2 abuts against the end abutment member 111, the first reinforcement member 112 is arranged on the end abutment member 111, the second reinforcement member 113 is arranged on the end abutment member 111 and is spaced opposite to the first reinforcement member 112, the first water pump limiting member 121 is located between the first reinforcement member 112 and the second reinforcement member 113 and is connected to the first reinforcement member 112 and the second reinforcement member 113 respectively, the second water pump limiting member 122 is located between the first reinforcement member 112 and the second reinforcement member 113 and there is a gap between the second water pump limiting member 122 and the first reinforcement member 112 and between the second water pump limiting member 122 and the second reinforcement member 113.

[0101] Since the first water pump limiter 121 is located between the first reinforcement 112 and the second reinforcement 113 and is respectively connected to the first reinforcement 112 and the second reinforcement 113, the first reinforcement 112 and the second reinforcement 113 can fix the first water pump limiter 121 from both sides of the first water pump limiter 121, so that the first water pump limiter 121 is more durable and not easy to deform.

[0102] Since the second water pump stopper 122 is located between the first reinforcement 112 and the second reinforcement 113, and there is a gap between the second water pump stopper 122 and the first reinforcement 112 and between the second water pump stopper 122 and the second reinforcement 113, such a configuration, on the one hand, when the water pump 2 is placed in the water pump limit space 10, the placement state of the water pump 2 can be very conveniently observed through the gap, which is convenient for timely adjustment when the placement position of the water pump 2 is incorrect, so that the installation accuracy of the water pump in the water pump limit space 10 is higher. On the other hand, it can also reduce the injection molding materials and reduce the manufacturing cost of the water pump fixing bracket 1. On the other hand, it is also convenient for the demolding of the mold after injection molding.

[0103] In some embodiments, see Figure 2 The third water pump stopper 123 is located between the first reinforcement member 112 and the second reinforcement member 113 and is connected to the first reinforcement member 112 and the second reinforcement member 113 respectively.

[0104] By locating the third water pump limiter 123 between the first reinforcement 112 and the second reinforcement 113 and connecting to the first reinforcement 112 and the second reinforcement 113 respectively, the first reinforcement 112 and the second reinforcement 113 can fix the third water pump limiter 123 from both sides of the third water pump limiter 123, so that the third water pump limiter 123 is stronger and more durable and not easy to deform.

[0105] It should be noted that the above-mentioned end abutment member 111, the first water pump limit member 121, the second water pump limit member 122 and the third water pump limit member 123 can all be plate-like structures. Of course, the end abutment member 111, the first water pump limit member 121, the second water pump limit member 122 and the third water pump limit member 123 can all be other possible structures, which is not limited to the present embodiment.

[0106] In some embodiments, see Figure 5 and Figure 6 The water pump fixing bracket 1 also includes: a battery limiting structure 14, which is arranged on the main frame 11, and the battery limiting structure 14 defines a battery limiting space 140. The water pump assembly 100 also includes a battery 3, and the battery 3 is limited in the battery limiting space 140.

[0107] Since the water pump fixing bracket 1 also includes a battery limiting structure 14, and the battery limiting space 140 defined by the battery limiting structure 14 can be used to limit the battery 3, the water pump fixing bracket 1 has the function of fixing the battery 3 in addition to the function of fixing the water pump 2, making the water pump fixing bracket 1 more functional and more integrated.

[0108] There are many ways to implement the battery limiting structure 14. As long as the battery limiting structure 14 can define the battery limiting space 140 and limit the battery 3 in the battery limiting space 140, the present embodiment does not limit the implementation of the battery limiting structure 14. In one possible implementation, see Figure 5 and Figure 6 The battery limiting structure 14 includes: a first battery limiting member 141, a second battery limiting member 142 and a third battery limiting member 143, wherein the first battery limiting member 141 is arranged on the main frame 11, the first battery limiting member 141 has a first supporting surface 1411, and the first supporting surface 1411 is used to support one end of the battery 3, the second battery limiting member 142 is arranged on the main frame 11, the second battery limiting member 142 has a second supporting surface (not shown in the figure), the third battery limiting member 143 is arranged on the main frame 11, the third battery limiting member 143 has a third supporting surface 1431, the second supporting surface is opposite to the third supporting surface 1431, the second supporting surface and the third supporting surface 1431 are both used to abut against the peripheral wall of the battery 3, the first supporting surface 1411, the second supporting surface and the third supporting surface 1431 define the battery limiting space 140.

[0109] Since the first supporting surface 1411 supports one end of the battery 3, and the second supporting surface 1431 is opposite to and respectively abuts against the peripheral wall of the battery 3, the first supporting surface 1411, the second supporting surface and the third supporting surface 1431 can limit the battery 3 from at least three directions. On the one hand, the battery 3 can be stably placed in the battery limiting space 140. On the other hand, the method for fixing the battery 3 is also very simple, which can reduce the cost of the battery limiting structure 14.

[0110] Among them, the above-mentioned first battery limiter 141, the second battery limiter 142 and the third battery limiter 143 can all be plate-shaped structures. Of course, the first battery limiter 141, the second battery limiter 142 and the third battery limiter 143 can also be other possible shapes, which is not limited to this embodiment.

[0111] Considering that when the battery 3 is placed in the battery limiting space 140, since one end of the battery 3 is supported on the first supporting surface 1411, the friction between the one end of the battery 3 and the first supporting surface 1411 is relatively large, which may cause the battery 3 to be worn during the installation or removal of the battery. In some embodiments, see Figure 6 A supporting rib 14111 may be provided on the first supporting surface 1411, and one end of the battery 3 is supported on the side wall of the supporting rib 14111. In this way, the friction between the battery 3 and the first supporting surface 1411 can be reduced, so that the battery 3 is not easily worn.

[0112] The number of the supporting ribs 14111 may be two, three, four, etc., which is not limited in this embodiment.

[0113] In some embodiments, see Figure 6 The second battery stopper 142 is perpendicular to the first support surface 1411 ( Figure 6 There is a gap between the two ends of the second battery stopper 142 in the direction perpendicular to the first support surface 1411 and the main frame 11. By providing a gap between the two ends of the second battery stopper 142 in the direction perpendicular to the first support surface 1411 and the main frame 11, on the one hand, it is convenient to demould the water pump fixing bracket 1 during injection molding, and on the other hand, it can also reduce the material used during injection molding.

[0114] Further, in some embodiments, see Figure 6, there is a gap between the two ends of the third battery stopper 143 in the direction perpendicular to the first support surface 1411 and the main frame 11. Similar to the gap between the two ends of the second battery stopper 142 in the direction perpendicular to the first support surface 1411 and the main frame 11, by making the gap between the two ends of the third battery stopper 143 in the direction perpendicular to the first support surface 1411 and the main frame 11, it can also make the water pump fixing bracket 1 easier to demold during injection molding and reduce the material used during injection molding.

[0115] In some embodiments, see Figure 7 The water pump fixing bracket 1 also includes a circuit board mounting structure 16 , which is disposed on the main frame 11 . The water pump assembly 100 also includes a circuit board 4 , which is mounted on the circuit board mounting structure 16 .

[0116] Since the circuit board mounting structure 16 is disposed on the main frame 11, when the circuit board 4 needs to be fixed to the water pump fixing bracket 1, it can be realized through the circuit board mounting structure 16. In this way, the water pump fixing bracket 1 can also integrate the function of fixing the circuit board 4, and the integration is higher.

[0117] Among them, see Figure 7 The above-mentioned circuit board mounting structure 16 can be a threaded hole set on the main frame 11, and the number of threaded holes can be multiple. Of course, the circuit board mounting structure 16 can also be other possible structures, as long as it can achieve the purpose of installing the circuit board 4 on the circuit board mounting structure 16. This embodiment does not limit the circuit board mounting structure 16.

[0118] In some embodiments, see Figure 2 and Figure 8 The water pump fixing bracket 1 also includes a water pump outlet pipe 15, which is arranged on the main frame 11, and one end of the water pump outlet pipe 15 is connected to the water pump limiting space 10 and is used to connect with the water outlet 22 of the water pump 2, and the other end of the water pump outlet pipe 15 is used to install the nozzle 5.

[0119] When the water pump outlet pipe 15 is provided on the main frame 11, when the water pump 2 is moved along the first direction ( Figure 2 When the water pump 2 is pushed into the water pump limiting space 10 (in the middle Z-axis direction), the water outlet 22 of the water pump 2 can be connected with one end of the water pump outlet pipe 15, so that the water in the water pump 2 can be pumped into the water pump outlet pipe 15 through the water outlet 22. Then, since the other end of the water pump outlet pipe 15 can be installed with a nozzle 5, the water pumped into the water pump outlet pipe 15 can be further sprayed out through the nozzle 5, thereby achieving the purpose of flushing.

[0120] It can be seen that by providing the water pump outlet pipe 15 , the water outlet 22 of the water pump 2 can be connected to the nozzle 5 , which provides a basis for subsequently spraying the water of the water pump 2 through the nozzle 5 .

[0121] In order to avoid water leakage at the joint between the water outlet 22 of the water pump 2 and the water pump outlet pipe 15, or at the joint between the water pump outlet pipe 15 and the nozzle 5, waterproof rubber rings can be provided at the two joints respectively, so that water leakage can be avoided.

[0122] In order to avoid interference between the water inlet 23 of the water pump 2 and the main frame 11 when the water pump 2 is pushed into the water pump limiting space 10, in some embodiments, see Figure 2 and Fig. 9 A avoidance hole 110 may be provided on the main frame 11, and the water inlet 23 passes through the avoidance hole 110 and is exposed outside the water pump limit space 10. On the one hand, it can avoid the interference between the water inlet 23 and the main frame 11. On the other hand, it can also make the water inlet 23 exposed outside the water pump limit space 10, which provides convenience for the subsequent connection of the water inlet pipe 6 at the water inlet 23.

[0123] Specifically, see Fig. 9 One end of the water inlet pipe 6 can be connected to the water inlet 23, the other end of the water inlet pipe 6 is connected to the first end of the connecting pipe 7, and the second end of the connecting pipe 7 can be connected to the water tank. In this way, when the water pump 2 starts working, the water in the water tank can be sucked into the water pump 2 through the connecting pipe 7, the water inlet pipe 6 and the water inlet 23 in sequence.

[0124] In order to avoid water leakage at the joint between the water inlet pipe 6 and the connecting pipe 7, the inner diameter of the water inlet pipe 6 can be larger than the outer diameter of the connecting pipe 7, and the connecting pipe 7 is inserted into the water inlet pipe 6. In this way, water leakage at the joint between the water inlet pipe 6 and the connecting pipe 7 can be avoided.

[0125] Furthermore, in order to better avoid water leakage at the joint between the water inlet pipe 6 and the connecting pipe 7, in some embodiments, the outer wall of the connecting pipe 7 can be stepped. In this way, on the one hand, it is convenient to insert the connecting pipe 7 into the water inlet pipe 6, and on the other hand, it can also better avoid water leakage at the joint between the water inlet pipe 6 and the connecting pipe 7.

[0126] In order to prevent the water inlet pipe 6 from shaking around, in some embodiments, see Fig. 9 A water pipe guide rib 151 is arranged on the outer wall of the water pump outlet pipe 15 .

[0127] By setting the water pipe guide rib 151, on the one hand, it can play a role in fixing the position of the water inlet pipe 6 and prevent the water inlet pipe 6 from shaking around. On the other hand, the water pipe guide rib 151 can also guide the arrangement path of the water inlet pipe 6, so that the trajectory of the water inlet pipe 6 is relatively rounded, avoiding wrinkles, and thus better ensuring that the water in the water inlet pipe 6 can flow smoothly.

[0128] In some embodiments, see Fig. 9 The number of the water pipe guide ribs 151 is multiple, and the multiple water pipe guide ribs 151 are arranged along the axial direction of the water pump outlet pipe 15 ( Fig. 9 The water pipe guide ribs 151 are arranged at intervals in the middle Z-axis direction, and a water pipe guide channel 1510 is formed between two adjacent water pipe guide ribs 151.

[0129] Since a water pipe guide channel 1510 is formed between two adjacent water pipe guide ribs 151, by passing the water inlet pipe 6 through the water pipe guide channel 1510, the water inlet pipe 6 can be fixed and the arrangement path of the water inlet pipe 6 can be guided, which is very convenient and quick.

[0130] In some embodiments, see Figure 1 and Figure 2 The fastener 13 includes: a connecting portion 131 and a clamping portion 132, wherein the connecting portion 131 is connected to the main frame 11, the clamping portion 132 is connected to the connecting portion 131 and protrudes from the connecting portion 131 along a direction close to the water pump limiting space 10, and the clamping portion 132 is used to clamp with the water pump 2.

[0131] Since the clamping portion 132 is connected to the connecting portion 131 and protrudes from the connecting portion 131 in a direction close to the water pump limiting space 10, when the water pump 2 is placed in the water pump limiting space 10, the clamping portion 132 can be clamped with the water pump 2, thereby achieving the purpose of fixing the water pump 2 in the water pump limiting space 10.

[0132] In order to more firmly fix the water pump 2 in the water pump limiting space 10, the number of the above-mentioned fasteners 13 can be multiple. Specifically, the number of the fasteners 13 can be two, three or four, etc. This embodiment does not limit the number of the fasteners 13.

[0133] Wherein, in some embodiments, see Figure 2 The above-mentioned clamping portion 132 can be elastically deformed in a direction close to or away from the water pump limiting space 10, so that the clamping portion 132 is clamped into or disengaged from the buckling portion 24 of the water pump 2.

[0134] Specifically, when the water pump 2 is pushed into the water pump limiting space 10, the peripheral wall of the water pump 2 can be brought into contact with the clamping portion 132, thereby causing the clamping portion 132 to be subjected to an external force in a direction away from the water pump limiting space 10. At this time, the clamping portion 132 can be elastically deformed in a direction away from the water pump limiting space 10. As the water pump 2 continues to be pushed in, when the water pump 2 is pushed into place, the snap-fitting portion 24 of the water pump 2 just reaches the snap-fitting portion 132. The snap-fitting portion 24 can be a sink recessed in the peripheral wall of the water pump 2. In this way, the snap-fitting portion 132 loses the external force. At this time, the snap-fitting portion 132 can be reset in a direction close to the water pump limiting space 10 under the action of its own elastic force, thereby achieving the purpose of snapping the snap-fitting portion 132 to the snap-fitting portion 24 of the water pump 2.

[0135] When the water pump 2 needs to be removed from the water pump limiting space 10 , the deformation process of the clamping portion 132 is exactly opposite to the process of pushing the water pump 2 into the water pump limiting space 10 , which will not be described in detail here.

[0136] In order to ensure that the snap-on portion 132 has good elasticity, in some embodiments, the snap-on component 13 may be an ABS (Acrylonitrile Butadiene Styrene) snap-on component. Of course, the snap-on component 13 may also be a snap-on component made of other materials, as long as it can ensure that the snap-on portion 132 has good elasticity. This embodiment does not limit this.

[0137] In some embodiments, see Figure 2 , the water pump 2 moves along the first direction ( Figure 2 The water pump 2 is pushed into the water pump limiting space 10 in the middle Z-axis direction to accommodate the water pump 2 in the water pump limiting space 10, the connecting portion 131 and the clamping portion 132 are connected in sequence along the first direction, and a side of the connecting portion 131 facing the water pump limiting space 10 is connected to a side of the clamping portion 132 facing the water pump limiting space 10 through a smooth guiding surface 133.

[0138] By connecting the side of the connecting portion 131 facing the water pump limiting space 10 and the side of the clamping portion 132 facing the water pump limiting space 10 through a smooth guiding surface 133, the guiding surface 133 can guide the water pump 2 when the water pump 2 is pushed into the water pump limiting space 10 along the first direction, so that the water pump 2 can be pushed into the water pump limiting space 10 very smoothly, and the blocking of the clamping portion 132 to the pushing of the water pump 2 can be avoided.

[0139] In order to ensure that the connection portion 131 has a strong mechanical strength, in some embodiments, see Fig.10 , a reinforcing rib 134 is provided on the connecting portion 131. By providing the reinforcing rib 134, the connecting portion 131 can be made more durable and not easily deformed.

[0140] The number of the reinforcing ribs 134 may be one, two, three, etc., which is not limited in this embodiment.

[0141] In some embodiments, the water pump fixing bracket 1 is an integrally molded structure. By making the water pump fixing bracket 1 an integrally molded structure, the water pump fixing bracket 1 can be injection molded by using a set of molds, which can save the number of molds, simplify the processing steps of the water pump fixing bracket 1, and reduce the processing cost of the water pump fixing bracket 1.

[0142] See also Fig.11 This embodiment provides a personal care flushing device 200 , which includes a water pump assembly 100 .

[0143] Among them, the structure of the water pump assembly 100 can be the same as the structure of the water pump assembly 100 described in any of the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description of the water pump assembly 100 in the above embodiments, and this embodiment will not be repeated here.

[0144] In this embodiment, since the water pump assembly 100 can make it convenient and quick to fix the water pump 2 to the water pump fixing bracket 1, based on this, when the personal care flushing device 200 includes the water pump assembly 100, the water pump 2 can be very conveniently fixed in the inner cavity of the personal care flushing device 200, making the assembly work of the personal care flushing device 200 convenient and quick.

[0145] Among them, the above-mentioned personal care flushing device 200 can be a nasal irrigator or a tooth irrigator, etc., which is not limited in this embodiment.
