[0040] To make the purpose, technical solutions, and advantages of one or more embodiments of the present invention more clear, the technical solutions of one or more embodiments of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of one or more embodiments of the present invention.

[0041] During use, a toothbrush typically utilizes a drive motor within the water pump unit to drive the pumping components within the water pump unit, thereby transferring the toothbrush fluid from the water tank unit to the toothbrush unit. During use, the drive motor and pumping components within the water pump unit generate significant vibrations. In the prior art, the water pump unit is typically mounted directly on the bottom shell of the toothbrush. Since the water pump unit is directly connected to the body of the toothbrush, the vibrations generated by the water pump unit during operation are directly transmitted to the body of the toothbrush, causing the body of the toothbrush to vibrate significantly, impacting the user experience.

[0042] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] like Figures 1 to 8 As shown, a tooth cleaner provided by the present invention may include: a body 1; the body 1 may include: a water pump unit 11, a body shell 12, a water tank unit 13, and a tooth cleaning unit 14; wherein, the body shell 12 may include an outer shell 121, a first partition 122, and a bottom shell 123; the first partition 122 may be arranged in a cavity enclosed by the outer shell 121; the bottom end of the outer shell 121 is connected to the bottom shell 123.

[0044] In the embodiments of this specification, the water tank unit 13 is typically mounted on the housing 121. Optionally, the water tank unit 13 can be integrally formed with the housing 12 or removably connected to the housing 121 of the housing 12. Furthermore, the water tank unit 13 can be used to supply cleaning fluid to the tooth cleaning unit 14. When using the tooth cleaning device, the user can inject the cleaning fluid into the water tank unit 13. In practice, the cleaning fluid can be a liquid used to clean teeth or alleviate oral diseases, such as pure water or saline.

[0045] The tooth cleaning unit 14 can be detachably connected to the housing 121. Specifically, the tooth cleaning unit 14 can be connected to the housing 121 by magnetic attraction, suspension or snap connection, etc., which is not specifically limited here.

[0046] The water pump unit 11 is generally disposed in the body housing 12 ; the water pump unit 11 can be used to pump dental cleaning fluid from the water tank unit 13 into the dental cleaning unit 14 .

[0047] In the embodiment of this specification, the water pump unit 11 can be installed on the first partition 122 in the body shell 12 through the installation column 115; so that there is a preset gap between the water pump unit 11 and the bottom shell 123 of the body shell 12; to prevent the water pump unit 11 from directly transmitting vibration and noise to the bottom shell 123, so as to reduce the vibration of the body shell 12.

[0048] Optionally, the water pump unit 11 may be suspended and fixed on the first partition 122 using the mounting column 115 ; or the water pump unit 11 may be directly disposed on the first partition 122 and fixed using the mounting column 115 .

[0049] In addition, the mounting column 115 can be a connecting part that can absorb or reduce vibration. The water pump unit 11 is suspended and fixed on the first partition 122 by using the mounting column 115, and the mounting column 115 is connected to the water pump unit 11, so that the vibration energy of the water pump unit 11 can be transmitted through the mounting column 115, and the vibration is transmitted to the first partition, thereby avoiding the water pump unit 11 directly transmitting the vibration to the bottom shell 123, effectively reducing the vibration of the fuselage shell 12; and because the mounting column 115 can absorb or reduce vibration, the vibration transmitted by the mounting column 115 further reduces the vibration transmitted to the fuselage shell 12.

[0050] In the embodiment of this specification, the first partition 122 can be integrally formed with the outer shell 121, or can be detachably connected to the outer shell 121; no specific limitation is made here.

[0051] Optionally, a first vibration damper 124 may be provided on the first partition 122 , and the water pump unit 11 may be connected to the first vibration damper 124 by connecting the mounting column 115 to the fastener 125 .

[0052] In practical applications, the fastener 125 may be a bolt or a screw, or other fixing devices, which are not specifically limited here.

[0053] In the embodiment of this specification, the mounting column 115 is directly fixed to the first vibration damper 124 of the first partition 122 using a fastener 125, so that the vibration of the water pump unit 11 can be directly transmitted to the first vibration damper 124, and the first vibration damper 124 is used to reduce vibration to prevent the vibration from being directly transmitted to the fuselage shell 12 through the first partition 122, thereby effectively reducing the vibration transmitted to the fuselage shell 12 and reducing noise.

[0054] Optionally, when the water pump unit 11 is connected to the first vibration damper 124 by connecting the fastener 125 to the mounting column 115, the mounting column 115 can be located below the first vibration damper 124, or the end of the mounting column 115 close to the water pump unit 11 can be in contact with the first vibration damper 124; the fastener 125 can pass through the first vibration damper 124 to be connected to the mounting column 115; in addition, a through hole for the fastener 125 to pass through can be provided in the first vibration damper 124.

[0055] In the embodiments of this specification, when fasteners 125 are used to connect to mounting posts 115, mounting posts 115 can be positioned below first vibration dampeners 124, or the end of mounting posts 115 closest to the water pump unit 11 can be placed in contact with the first vibration dampener 124; the stem of fastener 125 can then pass through the first vibration dampener 124 to connect to mounting posts 115. It will be appreciated that the cross-sectional area of ​​the head of fastener 125 should be larger than the cross-sectional area of ​​the through hole in the first vibration dampener 124 through which the stem of fastener 125 passes, to ensure that the water pump unit 11 can be secured to the first vibration dampener 124.

[0056] Optionally, when the water pump unit 11 is connected to the first vibration damper 124 by connecting the mounting column 115 with the fastener 125, the mounting column 115 is at least partially embedded in the first vibration damper 124, and the fastener 125 is connected to the mounting column 115; a through hole for the fastener 125 and / or the mounting column 115 to pass through can be provided in the first vibration damper 124.

[0057] In the embodiment of this specification, when the fastener 125 is used to connect to the mounting post 115, the mounting post 115 can pass through the first vibration damper 124 to connect to the fastener 125; or it can be only partially embedded in the first fastener 125 but not pass through the first vibration damper 124 to connect to the fastener 125. It can be understood that the cross-sectional area of ​​the head of the fastener 125 is larger than the cross-sectional area of ​​the through hole in the first vibration damper 124 for the fastener 125 and / or the mounting post 115 to pass through.

[0058] Optionally, in order to facilitate improving the stability of the connection between the first vibration damper 124 and the first partition 122, in the embodiment of the present specification, a mounting groove 1221 for mounting the first vibration damper 124 is also provided on the first partition 122, wherein the mounting groove 1221 is provided with a step surface 12211, and the first vibration damper 124 is provided with a limiting surface 1241, and the step surface 12211 can cooperate with the limiting surface 1241.

[0059] Figure 4 It is a schematic diagram of the three-dimensional structure of the body shell of a tooth cleaner provided in an embodiment of this specification. Figure 5 This is a schematic diagram of the structure of a first vibration damping member provided in the embodiment of this specification. Figure 4 and Figure 5 As shown, the first vibration damper 124 can have an interference fit with the mounting groove 1221. Specifically, the portion above the limiting surface 1241 of the first vibration damper 124 can be disposed within the hollowed-out area of ​​the mounting groove 1221 and have an interference fit with the hollowed-out area of ​​the mounting groove 1221. The limiting surface 1241 of the first vibration damper 124 precisely fits with the stepped surface 12211 of the mounting groove 1221, thereby further stabilizing the connection between the first vibration damper 124 and the first partition 122.

[0060] Optionally, the first separator 122 and the first vibration damper 124 may also be injection molded twice.

[0061] Optionally, there may be multiple mounting slots 1221 , and the first vibration damper 124 may match the multiple mounting slots 1221 ;

[0062] In actual applications, there can be multiple mounting grooves 1221 and they can be distributed on the first spacer, and the first vibration damper 124 can have a limiting surface 1241 that matches the step surfaces 12211 in the multiple mounting grooves 1221; it can be understood that the thickness of other parts of the first vibration damper 124 except for the position matching the mounting groove 1221 can be less than the thickness at the position matching the mounting groove 1221.

[0063] Optionally, there may be a plurality of mounting slots 1221 , and the number of first vibration dampers 124 may be the same as the number of mounting slots 1221 , and the first vibration dampers 124 match the corresponding mounting slots 1221 .

[0064] In actual applications, the number of mounting slots 1221 or the number of first vibration dampers 124 may be greater than or equal to the number of mounting positions of the mounting posts 115 ; understandably, the positions of some mounting slots 1221 may be consistent with the mounting positions of the mounting posts 115 .

[0065] It is understandable that the position, shape, and size of the first vibration damper 124 should match the position, shape, and size of the corresponding mounting slot 1221 .

[0066] Optionally, there may be only one mounting groove 1221 , and the first vibration damper 124 matches the mounting groove 1221 . The first vibration damper 124 may include one or more through holes for fixing the mounting column 115 .

[0067] In the embodiment of this specification, the mounting groove 1221 can be a relatively large groove structure provided in the first partition 122. It is understood that the shape and size of the first vibration damper 124 should match the shape and size of the mounting groove 1221. The first vibration damper 124 can be provided with a plurality of through holes for fixing the mounting posts 115 to facilitate fixing the mounting posts 115.

[0068] In any of the above embodiments, the shape of the mounting groove 1221 may be regular or irregular, which may be determined according to actual application and is not specifically limited here.

[0069] In the embodiments of this specification, to prevent vibrations from the water pump unit 11 from being directly transmitted to the housing 12 through the first partition 122, the mounting slot 1221 of the first partition 122 may be hollowed out. Furthermore, the first vibration damper 124 may be a vibration damper of a certain thickness with a stepped surface 12211 to facilitate multi-directional vibration reduction, thereby reducing vibrations transmitted to the housing 12 and enhancing the vibration reduction effect of the first vibration damper 124. Specifically, the thickness of the first vibration damper 124 may be 10 mm or greater. The thickness of the first vibration damper 124 can be selected based on actual needs and is not specifically limited here.

[0070] In the embodiment of this specification, the water pump unit 11 may include a first driving motor 111 , a transmission component 113 and a water pumping component 112 .

[0071] In actual application, the first drive motor 111 can drive the water pumping component 112 to work through the transmission component 113, so that the dental cleaning fluid in the water tank unit 13 can be pumped into the dental cleaning unit 14. The water pumping component 112 can be a piston pump or a diaphragm pump; specifically, the water pumping component 112 can include a pump body and a piston. The transmission component 113 can include a motor gear, an eccentric wheel, and a connecting rod. The motor shaft of the first drive motor 111 can be fixedly connected to the motor gear; the motor gear is meshed with the eccentric wheel gear; one end of the connecting rod is provided on the eccentric wheel and is rotationally connected to the eccentric wheel; the other end is rotationally connected to the piston in the pump body of the water pumping component 112. When the first drive motor 111 is working, the motor shaft can drive the eccentric wheel to rotate through the motor gear, and the eccentric wheel can drive the piston to reciprocate in the pump body through the connecting rod.

[0072] The pump body of the water pump component 112 may be provided with a water inlet and a water outlet; the water inlet may be connected to the water outlet of the water tank unit 13 via a first water supply pipe; the water outlet may be connected to the tooth cleaning unit 14 via a second water supply pipe; in addition, one-way flow valves may be provided at the water inlet and the water outlet to ensure one-way flow of the tooth cleaning fluid and prevent backflow of the tooth cleaning fluid. Specifically, when the piston in the pump body moves outward under the drive of the first drive motor 111, the pressure in the pump body decreases, allowing the tooth cleaning fluid in the water tank unit 13 to enter the pump body through the water inlet; and when the piston in the pump body moves inward under the drive of the first drive motor 111, the pressure in the pump body increases, allowing the tooth cleaning fluid in the pump body to enter the tooth cleaning unit 14 through the water outlet. Since a one-way flow valve is provided at the water inlet end, the tooth cleaning fluid cannot flow back into the water tank unit 13, but can only flow from the water outlet end of the water pump component 112 to the tooth cleaning unit 14; similarly, when the piston in the pump body moves outward under the drive of the first drive motor 111, since a one-way flow valve is provided at the water outlet end of the water pump component 112, the tooth cleaning fluid cannot flow back from the tooth cleaning unit 14 into the pump body, but can only enter the pump body from the water tank unit 13.

[0073] Optionally, the water pump unit 11 may further include a mounting component 114 ; the mounting component 114 may be used to mount the first drive motor 111 , the transmission component 113 and the water pumping component 112 .

[0075] Optionally, the installation component 114 may include a accommodating cavity; the first drive motor 111 and the transmission component 113 may be arranged in the accommodating cavity, and the water pumping component 112 may be sealed and connected to the accommodating cavity; or, the installation component 114 may include a accommodating cavity; the transmission component 113 may be arranged in the accommodating cavity; and the first drive motor 111 is arranged outside the accommodating cavity.

[0076] In the embodiment of this specification, the installation component 114 may be an installation box having an accommodating cavity, and the installation box may be a sound-absorbing box capable of reducing noise.

[0077] In the embodiment of this specification, the first drive motor 111 and the transmission component 113 can be arranged in the accommodating cavity; the first drive motor 111 and the transmission component 113 are arranged in the accommodating cavity, which can facilitate the installation and fixation of the water pump unit 11 on the one hand; on the other hand, it can effectively reduce the noise generated by the first drive motor 111 and the transmission component 113 during operation.

[0078] In the embodiment of this specification, a seal may be provided between the water pumping component 112 and the accommodating chamber to prevent the first driving motor 111 from being damaged due to water leakage when the water pumping component leaks due to aging.

[0079] Figure 6 This is a schematic diagram of the structure of the installation components of a toothbrush provided in the embodiment of this specification.

[0080] Optionally, one end of the water pump unit 11 close to the water pumping component can be connected to the second partition through a second vibration damper 126 , and the second partition can be disposed in a cavity enclosed by the fuselage shell 12 .

[0081] Typically, the mounting post 115 can be provided at an end of the mounting component 114 near the first drive motor 111 to facilitate connecting the motor and transmission component 113 to the first partition 122. In the embodiment of this specification, to prevent the water pumping component 112 from directly transmitting vibrations to the bottom housing 123, a second vibration damper 126 can be provided at an end of the water pump unit 11 near the water pumping component 112, and the water pumping component 112 can be connected to the second partition using the second vibration damper 126.

[0082] In the embodiments of this specification, the second partition and the first partition 122 can be the same partition, with the mounting post 115 and the second vibration damper 126 connected to different regions of the partition. The second partition and the first partition 122 can also be located at different heights and / or in different regions within the cavity enclosed by the housing 121.

[0086] The first vibration damper 124 and the second vibration damper 126 can be made of rubber or silicone. The second vibration damper 126 can be made of the same material as the first vibration damper 124 or a different material, which is not specifically limited here.

[0087] Figure 8 This is a schematic diagram of a tooth cleaning unit structure provided in the embodiment of this specification. Figure 8 As shown, the teeth cleaning unit 14 may include a cleaning member 141 and a handheld portion 142.
