[0036] Figure 3 The structural diagram of the tooth cleaning component provided in this manual is as follows: Figure 3 As shown, the oral cleaning device of the present invention includes a tooth cleaning assembly 6 comprising a cleaning portion 601 and a handle portion 602. The tooth cleaning assembly 6 can be detachably connected to the housing 1 by means of magnetic attraction, suspension, buckling, etc. The handle portion 602 is detachably connected to the cleaning portion 601.

Such a configuration can provide a channel for liquid to flow from the drive shaft 6022 into the cleaning portion 601.

[0037] Figure 4 The structural diagram of the vibration damping member provided in this manual is as follows: Figure 4As shown, in an embodiment of the present invention, the vibration damper 3 includes a mounting portion 301 for mounting the vibration damper 3 to the outer wall of the water pump mounting portion 802 and / or the water pump 4. The mounting portion 301 can be an annular structure having a circular, square, or polygonal shape. The mounting portion 301 is securely connected to the outer wall of the water pump mounting portion 802 and / or the water pump 4. The fit between the outer wall of the water pump mounting portion 802 and / or the water pump 4 and the mounting portion 301 can include any of a form fit, an interference fit, and a friction fit. Form fit can refer to the shapes of the outer wall of the water pump mounting portion 802 and / or the water pump 4 and the mounting portion 301 matching each other. For example, the joining surface of the two components can be circular, square, or a specific geometric shape, based on which the two components can be securely connected. An interference fit can refer to a certain degree of tightness between the outer wall of the water pump mounting portion 802 and / or the water pump 4 and the mounting portion 301, and the elasticity of the vibration damper 3 can ensure the secure connection between the two components. Friction fit may refer to relying on friction between the water pump mounting portion 802 and / or the outer wall of the water pump 4 and the mounting portion 301 to maintain a secure connection therebetween.

[0038] In another embodiment of the present invention, the cooperation between the outer wall of the water pump mounting portion 802 and / or the water pump 4 and the mounting portion 301 of the vibration damper 3 can refer to the cooperation between the outer wall of the water pump mounting portion 802 and / or the water pump 4 and the circumferentially spaced tooth-like structures on the inner annular surface of the mounting portion 301. There can be multiple tooth-like structures, with a predetermined distance between any two adjacent tooth-like structures. The tooth-like structures and the mounting portion 301 can be integrally formed or glued together. The maximum width of the connection between each tooth-like structure and the mounting portion 301 can be less than or equal to the width of the inner annular surface of the mounting portion 301. The connection between the tooth-like structures and the outer wall of the water pump mounting portion 802 and / or the water pump 4 can effectively reduce the contact area between the outer wall of the water pump mounting portion 802 and / or the water pump 4 and the mounting portion 301, thereby improving the ease with which the vibration damper 3 deforms. Furthermore, the deformation of the vibration damper 3 can effectively buffer the vibration amplitude of the water pump mounting portion 802 and / or the water pump 4, achieving a vibration reduction effect.

[0039] In another embodiment of the present invention, to further reduce the contact area between the water pump mounting portion 802 and / or the outer wall of the water pump 4 and the mounting portion 301 of the vibration damper 3, the cross-sectional area of the tooth-like structure provided on the inner annular surface of the mounting portion 301 can gradually decrease along the axial direction, starting from the inner annular surface. The end surface of the tooth-like structure away from the inner annular surface of the mounting portion 301 can be any of a flat surface, a concave-convex surface, and an arcuate surface. The end surface of the tooth-like structure away from the inner annular surface of the mounting portion 301 can also be provided with a plurality of small protrusions.

[0040] In an embodiment of the present invention, the support member 2 may include a fixing component provided on the inner wall of the bottom shell 102, such as a support plate, a support column, a beam, a support ring, a slide rail, a bracket, an anchor and other fixing components provided on the inner wall of the bottom shell 102. The support member 2 may also include fixing components located in the cavity enclosed by the outer shell 101, such as: spacers, dividing plates, support ribs, positioning columns, rivets, brackets and other fixing components. A mounting column is provided on the support member 2, and the mounting column and the support member 2 may be integrally formed, or the mounting column and the support member 2 may be connected by ultrasonic welding or glue or snaps or screws. The vibration damper 3 includes a fixing portion 302 for fixing the vibration damper 3 to the support member 2, and the fixing portion 302 may be an annular structure, and the fixing portion 302 may be sleeved on the mounting column. At this time, the cooperation between the fixing portion 302 and the mounting column may include any one of a shape fit, an interference fit and a friction fit. The fixing portion 302 can also be fixed to the mounting post by screws. In this case, the mounting post can be a hollow structure with internal threads. The screw is disposed within the hollow structure of the mounting post, and the area of the screw nut is larger than the area enclosed by the fixing portion. The vibration damper 3 can include multiple mounting portions 301 and / or multiple fixing portions 302.

[0041] Figure 5 The exploded structural diagram of the power assembly connected to the spacer provided for this specification is as follows: Figure 5 As shown, in the embodiment of the present invention, the support member 2 can be a spacer 201 located in the cavity enclosed by the housing 101. The spacer 201 is used to divide the cavity into an upper cavity and a lower cavity. The spacer 201 and the housing 101 can be integrally formed. The spacer 201 and the housing 101 can also be connected by ultrasonic welding, glue, snap fasteners, or screws. The edges of the spacer 201 can be fully or partially connected to the inner wall of the housing 101. The mounting post can be a first mounting post 2011 located at the bottom of the spacer 201. On the basis that one end of the vibration damper 3 is connected to the water pump mounting portion 802 and / or the water pump 4, and the other end of the vibration damper 3 is connected to the first mounting post 2011 at the bottom of the spacer 201, the water pump mounting portion 802 and / or the water pump 4 can be suspended on the spacer 201 through the vibration damper 3 and the first mounting post 2011.

[0042] In another embodiment of the present invention, the upper cavity can be used to place a power supply assembly, and the lower cavity can be used to place a power assembly, and the power supply assembly is used to provide electrical energy to the power assembly. The power assembly can also include a motor 7, and the other end of the mounting bracket 8 can have a motor mounting portion 801 for mounting the motor 7, and the motor 7 can be fixed to the motor mounting portion 801 by a motor fixing member 11. A second mounting column 2012 is provided between the motor mounting portion 801 and the spacer 201, and one end of the second mounting column 2012 can be directly connected to the motor mounting portion 801 or indirectly connected to the motor mounting portion 801 through a specific vibration-damping component, and the other end of the second mounting column 2012 is connected to the spacer 201, so that the motor mounting portion 801 and the motor 7 can be suspended on the spacer 201. Since the water pump mounting portion 802 and the water pump 4 can be suspended on the spacer 201 through the vibration damper 3 and the first mounting column 2011, the power assembly can be suspended on the spacer 201 through the first mounting column 2011 and the second mounting column 2012, so that the power assembly is spaced a preset distance from the bottom shell 102.

[0043] It should be noted that the first mounting post 2011 and the second mounting post 2012 are located at different positions on the spacer 201. The first mounting post 2011 and / or the second mounting post 2012 can be integrally formed with the spacer 201. The first mounting post 2011 and / or the second mounting post 2012 can also be connected to the spacer 201 by ultrasonic welding, glue, clips, or screws. Based on the fact that the vibration damper 3 can reduce vibration on the water pump mounting portion 802, the inventors discovered that by providing other vibration-damping components between the first mounting post 2011 and / or the second mounting post 2012 and the spacer 201, vibrations on the spacer 201, the first mounting post 2011, and / or the second mounting post 2012 can be absorbed. It was also discovered that by providing other vibration-damping components on the outer wall of the motor 7 and / or the motor mounting portion 801, vibrations on the motor 7 and / or the motor mounting portion 801 can be absorbed. Therefore, in order to improve the vibration reduction effect, the present invention may provide a first vibration reduction component 10 between the first mounting column 2011 and / or the second mounting column 2012 and the spacer 201 , and a second vibration reduction component 9 may be provided on the outer wall of the motor 7 and / or the motor mounting portion 801 .

[0044] Figure 6 Provide a schematic diagram of the structure of the second vibration damping component for this specification, such as Figure 6As shown, the second vibration-damping component 9 includes a first mounting portion 901 and a first fixing portion 902. The first mounting portion 901 may be an annular structure and is fastened to the outer wall of the motor 7 and / or the motor mounting portion 801. The first fixing portion 902 includes a first fixing unit 9021 and a second fixing unit 9022. The first fixing unit 9021 is fastened to the mounting post on the motor mounting portion 801 to fasten the motor 7 to the motor mounting portion 801. The second fixing unit 9022 is fastened to the second mounting post 2012 on the spacer 201 to fasten the motor 7 and the motor mounting portion 801 to the second mounting post 2012.

[0045] Figure 7 The exploded structure diagram of the power assembly connected to the support plate provided for this manual is as follows: Figure 7 As shown, in the embodiment of the present invention, the support member 2 can also be a support plate 202 provided on the bottom shell 102, and the support plate 202 and the bottom shell 102 can be connected by ultrasonic welding, glue, clips, or screws. A third mounting post 2021 for connecting the vibration damper 3 is provided on the support plate 202, and the fixing portion 302 of the vibration damper 3 is fastened to the third mounting post 2021. The mounting portion 301 of the vibration damper 3 is sleeved on the outer wall of the water pump mounting portion 802 and / or the water pump 4. In this way, the water pump mounting portion 802 and / or the water pump 4 can be lifted by the lifting force of the vibration damper 3, so that the water pump mounting portion 802 and / or the water pump 4 are separated from the bottom shell 102 by a preset distance. The power assembly also includes a transmission component, and the mounting bracket 8 also includes a transmission component accommodating portion 803 for accommodating the transmission component. The top of the transmission component accommodating portion 803 is a motor mounting portion 801. The transmission component accommodating portion 803 communicates with the water pump mounting portion 802. A third vibration-damping component 12 is disposed between the transmission component accommodating portion 803 and the support plate 202. The third vibration-damping component 12 includes a centrally raised bearing portion, to which the transmission component accommodating portion 803 is fixed, so that the transmission component accommodating portion 803 of the mounting bracket 8 is spaced a predetermined distance from the bottom shell 102, thereby separating the power assembly from the bottom shell 102. While the vibration damper 3 absorbs vibrations from the water pump mounting portion 802, the third vibration-damping component 12 is disposed between the power assembly and the support plate 202. Due to the deformation of the third vibration-damping component 12 itself and the distance between the power assembly and the bottom shell 102 achieved by the third vibration-damping component 12, the efficiency of vibration and noise reduction for the power assembly can be improved.

[0046] In another embodiment of the present invention, the transmission component includes a motor gear, an eccentric wheel, and a second fixed rod. The motor gear is connected to the output end of the motor 7, the motor gear is connected to the eccentric wheel, and the eccentric wheel is connected to the connecting rod 401 of the water pump 4 via the second fixed rod. The motor 7 drives the motor gear to rotate through the motor output end, the motor gear drives the eccentric wheel to rotate, and the eccentric wheel drives the connecting rod 401 of the water pump 4 to reciprocate, thereby driving the piston in the water pump 4 to reciprocate.

[0047] In the embodiment of the present utility model, Figure 4 As shown, the external structure of the vibration damper 3 can be any structure that meets the vibration damping requirements according to actual needs. Specifically, it can be a "T-shaped" structure. The vibration damper 3 can include a mounting portion 301, a fixing portion 302, and a connecting portion 303. The mounting portion 301, the fixing portion 302, and the connecting portion 303 can be integrally formed with each other, or can be connected by ultrasonic welding or glue. The mounting portion 301 and the fixing portion 302 are connected by the connecting portion 303. The mounting portion 301 can be located in the vertical line area of the "T-shaped" structure, and the fixing portion 302 can be located at both ends of the horizontal line area of the "T-shaped" structure. There is an intersection between the horizontal line area and the vertical line area of the "T-shaped" structure, and the connecting portion 303 is located in the area between the end points of the horizontal line area of the "T-shaped" structure and the intersection. When the vibration damper 3 is connected to the mounting post on the spacer 201, the vibration damper 3 can be used in an upright "T-shaped" configuration. When the vibration damper 3 is connected to the mounting post on the support plate 202, the vibration damper 3 can be used in an inverted "T-shaped" configuration. The connecting portion 303 may include a first connecting portion 3031 and a second connecting portion 3032, with the first connecting portion 3031 and the second connecting portion 3032 separated by a predetermined distance. Alternatively, the connecting portion may be composed of multiple sub-connecting portions, each of which is separated by a predetermined distance. This configuration can improve the ease with which the connecting portion can deform, thereby enhancing the vibration reduction effect of the vibration damper 3.

[0048] It should be noted that the external structure of the vibration damper 3 may also be an "I-shaped" structure. The positional relationship between the mounting portion, the fixing portion, and the connecting portion in the "I-shaped" vibration damper 3 can refer to the positional relationship between the three in the "T-shaped" vibration damper 3. The external structure of the vibration damper 3 may also be a structure composed of multiple "T-shaped" structures and / or multiple "I-shaped" structures. A connecting portion is provided between any adjacent "T-shaped" structures or "I-shaped" structures. The connecting portion is used to connect two "T-shaped" structures, two "I-shaped" structures, or one "T-shaped" structure and one "I-shaped" structure.
