[0029] To make the purpose, technical solutions, and advantages of one or more embodiments of this specification more clear, the technical solutions of one or more embodiments of this specification will be clearly and completely described below in conjunction with the specific embodiments of this specification and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, 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 this specification.

[0030] In an embodiment of the present specification, an oral cleaning device is provided. The device may include a base assembly, and the base assembly may include a first power assembly, a first shock absorbing assembly, and a shell. The shell may be formed by connecting a shell having a cavity and a bottom shell for encapsulating the base assembly. The first shock absorbing assembly may be placed between the first power assembly and the bottom shell. Specifically, the first power assembly may be installed on the mounting portion of the first shock absorbing assembly, and the fixing portion of the first shock absorbing assembly is used to connect the bottom shell to fix the first shock absorbing assembly on the bottom shell. There may be a gap between the mounting portion and the fixing portion in the first shock absorbing assembly so that the gap can be used as a buffer zone to reduce the vibration and noise generated when the first power assembly is working, thereby reducing the noise and the vibration transmitted to the shell of the oral cleaning device and improving the user experience. In addition, the first shock absorbing assembly can be made of a material with good shock absorption, sound insulation and buffering properties, and its own material properties can be used to further reduce shock. The design of separating the vibration generating component from the shell helps to further reduce the vibration transmitted to the outside of the device.

[0031] The technical solutions provided by the embodiments of this specification are described in detail below with reference to the accompanying drawings.

[0032] The embodiment of this specification provides an oral cleaning device for cleaning food residues in teeth and gums to protect the health of teeth and gums. Figures 1 to 6 As shown, the oral cleaning device may include a base component 1 , a water tank 2 and a teeth cleaning component 3 .

[0033] In the embodiments of this specification, the water tank 2 and the base assembly 1 are detachably connected, either by connecting the water tank and the base assembly via an external conduit or by connecting the water tank and the base assembly in a concave-convex manner, such as by having a downward protrusion on the water tank that mates with a groove on the base assembly. This is not specifically limited here and can be determined based on the actual structure of the oral cleaning device. The base assembly 1 may include a recessed portion so that the water tank can be placed on the recessed portion.

[0034] In the embodiment of this specification, the tooth cleaning component 3 is detachably connected to the base component 1, and can be connected by magnetic attraction, hanging, buckling, etc.; the tooth cleaning component may include a gripping portion and a care head, wherein the gripping portion and the care head are detachably connected, and the care head can be replaced, such as a brush head for brushing teeth, a nozzle for flushing teeth, etc. The gripping portion may contain a second power component so that the care head can be controlled to rotate based on the second power component to adjust the angle of the care head for user convenience. The second power component may include a second motor for driving the brush head to move or provide fluid through a flow channel, and may also include a drive shaft connected to the care head, so that the second motor body can drive the shaft to rotate and / or apply vibration motion to the drive shaft to control the vibration and / or rotation of the care head; wherein the drive shaft can be hollow in design to provide a fluid channel to facilitate the fluid to enter the care head from the drive shaft to perform corresponding operations, such as flushing teeth, brushing teeth, etc.

[0035] In the embodiment of this specification, the base assembly 1 may include a shell, a first power assembly and a first shock absorbing assembly 13. The shell may include an outer shell 11 and a bottom shell 12, and the bottom end of the shell is connected to the bottom shell. Specifically, the bottom end of the shell and the bottom shell may be integrally formed, or the bottom end of the shell and the bottom shell may be detachably mounted. The shell 11 may have a cavity so that the first power assembly can be placed in the cavity. The cavity may also accommodate components such as a control element and a power supply so that the operation mode of the oral cleaning device can be controlled based on the power supply and based on the control element. A certain space may be left between the first power assembly and the bottom shell 12 so that the first shock absorbing assembly 13 can be arranged between the first power assembly and the bottom shell 12.

[0036] In the embodiment of this specification, the first shock absorbing assembly 13 may include a fixing portion 1301 and a mounting portion 1302. The fixing portion may be used to fix the first shock absorbing assembly to the bottom shell to connect the bottom shell, thereby ensuring that the first shock absorbing assembly is securely mounted in the base assembly. The mounting portion may be used to mount the first power assembly, ensuring that the first power assembly is more stably positioned within the cavity. A gap may be provided between the fixing portion and the mounting portion, which may serve as a buffer zone to reduce vibrations during operation of the first power assembly, thereby reducing vibrations transmitted to the bottom shell. It is understood that the first shock absorbing assembly 13 may also serve as a sound insulation component to isolate some of the noise generated during operation of the first power assembly.

[0037] In the embodiment of this specification, the first shock absorbing assembly 13 may also include a connecting arm 1303; the connecting arm 1303 may be used to connect the fixing portion 1301 and the mounting portion 1302; the shape of the mounting portion 1302 may match the contour of the first power assembly so as to be able to carry the first power assembly while reducing the vibration generated by the first power assembly; the fixing portion may surround the periphery of the mounting portion and may be annular; at least two connecting arms are provided in the gap between the fixing portion and the mounting portion, one end of the connecting arm is connected to the mounting portion and the other end is connected to the fixing portion, and the connecting arm may be a bar or other shape. In addition to damping vibrations through the gap between the mounting portion and the fixing portion, the first shock absorbing assembly may also reduce some vibrations through its own deformation when the vibrations are transmitted from the mounting portion to the fixing portion and then to the shell through the connecting arm.

[0038] In the embodiments of this specification, if there are two connecting arms and the angle between the two connecting arms is greater than or equal to 150 degrees, the two connecting arms can be positioned within corresponding position ranges. For example, if one connecting arm is positioned in the left gap, the other connecting arm can be positioned in the right gap; or, if one connecting arm is positioned in the upper gap, the other connecting arm can be positioned in the lower gap. This avoids problems such as a loose connection or tilting between the mounting portion and the fixing portion. The lower surface of the mounting portion in the first shock absorber assembly is higher than the upper surface of the fixing portion.

[0039] In practical applications, 3, 6, 8, and other numbers of connecting arms can also be set in the gap to improve the stability of the connection between the mounting portion and the fixed portion. If the number of connecting arms is large, the angle between adjacent connecting arms can be reduced, and the distance between adjacent connecting arms can also be reduced. It can be understood that if the number of connecting arms is 6, 8, or more, and the length of the gap on the upper and lower sides is greater than the length of the gap on the left and right sides, the number of connecting arms set in the gap on the upper and lower sides can be more than the connecting arms set in the gap on the left and right sides. For example, if the number of connecting arms is 8, three connecting arms can be set in the gap on the upper and lower sides respectively; and one connecting arm can be set in the gap on the left and right sides respectively, so that the connection between the mounting portion and the fixed portion is more secure, and more vibration can be reduced through the deformation of the connecting arms.

[0040] In the embodiment of this specification, after the first shock-absorbing assembly is arranged between the first power assembly and the bottom shell, the mounting portion of the first shock-absorbing assembly and the bottom shell are spaced at a preset height, which can be 1 mm, 0.5 mm, etc., so that when the oral cleaning device is working, the space of the preset height between the mounting portion and the bottom shell can prevent the vibration generated by the first power assembly from being directly transmitted to the bottom shell, thereby achieving a shock-absorbing effect.

[0041] In the embodiment of this specification, the bottom shell 12 may include a fixing member 1201 and a bottom cover 1202; the bottom cover can be used to encapsulate the bottom of the base assembly. The bottom shell can be formed by connecting the bottom cover and the fixing member. The bottom cover and the fixing member can be connected by ultrasonic welding. Ultrasonic welding is a solid-state welding technology that uses high-frequency vibration waves to transmit to the contact surface of the workpiece to be welded. Under pressure, the contact surfaces of the two plastic parts rub against each other to generate heat, instantly melting and fusing, thereby forming a strong bond. It is often used to connect plastic and metal parts. Because no additional welding material is required during welding, the welded product is relatively clean and there will be no welding residue left to affect the use of the product. In actual applications, the bottom cover and the fixing member can also be connected by glue; the bottom cover and the fixing member can also be connected together by secondary injection molding; the bottom cover and the fixing member can also be fixedly connected by a snap connection; the bottom cover and the fixing member can also be connected by other existing fixing or connection methods, which are not specifically limited here.

[0042] In the embodiment of this specification, if the bottom shell includes a fixing part, the fixing part 1301 in the first shock absorbing assembly 13 can be fixed on the fixing part, and the mounting part 1302 can be connected to the first power assembly so that after installation, the mounting part and the fixing part are spaced at a preset height, thereby avoiding vibration directly transmitted from the mounting part to the fixing part, thereby reducing the vibration transmitted to the shell.

[0043] In the embodiment of this specification, the fixing member may include a connecting column 12012 and a mounting plate 12011. The mounting plate may be Figure 4 or Figure 6 The bottom portion of the fixing member 1201 shown is pointed to, and the connecting post can be Figure 4 or Figure 6 The portion of the upper end of the mounting plate pointed to by the fixing member 1201 shown. The first shock absorbing assembly may also include a limiting opening 1305, which may be sleeved on the connecting post to connect the first shock absorbing assembly to the fixing member, and may also limit the first shock absorbing assembly to a preset position to prevent the position of the first shock absorbing assembly from shifting when the oral cleaning device is working. The limiting opening in the first shock absorbing assembly may be a limiting component having an opening similar to the cross-sectional shape of the connecting post, and a smaller opening to prevent the limiting opening from being disconnected from the connecting post. Figure 4 As shown, after the limiting opening is sleeved over the connecting post, a portion of the connecting post may be uncovered by the limiting opening, and this portion may be less than 30%. This facilitates installation and removal of the first shock absorber assembly from the fixing member, and also limits the position of the first shock absorber assembly. Furthermore, the limiting opening and the connecting post may be connected using glue, and the method of connection between the two is not specifically limited herein.

[0044] In the embodiment of this specification, the first power assembly may include a mounting bracket 15, and some components may be placed in a cavity provided in the mounting bracket. Figure 5 This is a schematic diagram of the cross-sectional structure of a mounting bracket provided in an embodiment of this specification. Figure 5 As shown, the mounting bracket may include a receiving cavity for mounting the transmission component, may include a pump body mounting portion 1504 for mounting the pump body, the pump body mounting portion is communicated with the receiving cavity, and may further include a motor mounting portion 1505.

[0045] In the embodiments of this specification, the mounting portion and the mounting bracket are connected via fasteners. Specifically, the first shock-absorbing assembly may further include a connecting hole 1304, which may be located within a first groove on the mounting portion. The diameter of the first groove may be larger than the diameter of the connecting hole, and the wall of the connecting hole may be threaded. There may be at least one first groove. The bottom of the mounting bracket may have the same number of downward-facing first protrusions 1501 as the first grooves. The first protrusions may be hollow, with threads inside. The first protrusions of the mounting bracket may be mated with the first grooves of the mounting portion, thereby enhancing the secure connection between the mounting bracket and the first shock-absorbing assembly. A fastener 14 may be inserted through the connecting hole and into the hollow interior of the first protrusion of the mounting bracket to securely connect the mounting portion to the bottom of the mounting bracket. The nut size of the fastener may be larger than the size of the connecting hole. Alternatively, the mounting portion and the bottom of the mounting bracket may be connected using other conventional methods, such as gluing. The mounting portion may further include a predetermined number of second grooves, and the bottom of the mounting bracket may also include a predetermined number of downward-facing second protrusions 1502. The second grooves and the second protrusions may be mated with each other, further securing the connection between the mounting portion and the mounting bracket. It is understandable that Figure 5 For illustrative purposes only, the specific number of the first protrusions and the second protrusions may be set based on actual needs, and the number of the first protrusions or the second protrusions may be greater than or equal to one.

[0046] In the embodiment of this specification, the fixing portion 1301 may also have at least one upward third protrusion, so that the third protrusion can contact the periphery of the mounting bracket to play a supporting role, thereby avoiding the downward pressure generated by the mounting bracket on the mounting portion, causing the mounting portion to contact the bottom shell.

[0047] In the embodiments of this specification, the base assembly may further include a second shock-absorbing assembly, and the pump body mounting portion of the mounting bracket may be connected to the fixing member through the second shock-absorbing assembly. Specifically, the second shock-absorbing assembly may be sleeved on the outer shell of the pump body mounting portion, and the second shock-absorbing assembly may include at least two sleeve holes, which may be sleeved on the connecting column of the fixing member, thereby connecting the pump body mounting portion to the fixing member, so that the pump body mounting portion can also be suspended above the mounting plate of the fixing member, thereby reducing the vibration transmitted to the shell when the pump body is working and improving the user experience. The material of the first shock-absorbing assembly and the second shock-absorbing assembly may be rubber or silicone material, which has good shock absorption, sound insulation and buffering properties.

[0048] When the oral cleaning device of the embodiment of this specification is in operation, the output shaft of the first motor 16 can drive the gear to rotate, and the gear drives the eccentric wheel to rotate, and then the eccentric wheel can control the connecting rod to reciprocate in the pump body. The liquid in the water tank can flow into the pump body through the water inlet end assembly, and the connecting rod pushes the piston to move, so that the liquid can flow out of the pump body through the water outlet end assembly, and then flow into the base assembly so that the liquid can flow into the tooth cleaning assembly through the pipe in the base assembly. The motor mounting portion can isolate the first motor 16 from the accommodating cavity of the mounting bracket to prevent the piston from being worn due to long-term use, and the liquid from flowing into the accommodating cavity and then flowing to the first motor 16, causing the first motor 16 to malfunction and affecting the use of the oral cleaning device.

[0049] The oral cleaning device in the embodiment of this specification reduces the vibration and noise transmitted to the shell by the first power component when the oral cleaning device is working by setting a first shock-absorbing component between the first power component and the bottom shell, and setting a second shock-absorbing component between the pump body mounting part of the mounting bracket and the fixing part, thereby improving the user experience.
