The oral cleaner is equipped with a charging converter inside and a charging base outside the oral cleaner. The external power supply can charge the rechargeable battery through the charging base and charging converter.

[0004] However, the related oral cleaner has a problem of low assembly efficiency. Utility Model Content

[0063] Figure 1 This is a schematic diagram of an oral cleaning device provided in an embodiment of the present application. Figure 2 for Figure 1 A longitudinal sectional view of an oral cleaning device is shown. Figure 1 and Figure 2 The oral cleaning device provided in the embodiment of the present application may include an oral cleaning device 1000 and a cleaning accessory 2000, wherein the cleaning accessory 2000 may be a device capable of cleaning the oral cavity, such as a toothbrush head, a rinse head, or an integrated rinse head.

[0064] The following describes the specific structure of the oral cleaning device 1000 provided in the embodiment of the present application, taking the cleaning attachment 2000 as an integrated irrigating head as an example. Specifically, the cleaning attachment 2000 may include a brush body 2100, and the brush body 2100 may have a cavity 2200 and an outflow port 2300 communicating with the cavity 2200.

[0065] Continue to refer Figure 2 The oral cleaning device 1000 may include a housing 100, a power assembly, a charging receiving assembly, and a bracket assembly. In order to facilitate the user's grip, the housing 100 may be shaped like an elongated cylinder. The cross-section of the housing 100 may be circular or non-circular (such as D-shaped, elliptical, polygonal, etc.). The housing 100 may be slanted along a first direction X (such as Figure 2 The housing 100 extends in the up-down direction (in the first direction X), and the housing 100 may have a top end 160 and a bottom end 170 oppositely disposed in the first direction X. The interior of the housing 100 may be hollow to form an inner cavity of the housing 100.

[0066] The power assembly can be disposed in the inner cavity of the housing 100, and the power assembly can include a motor 200 and a pump mechanism 300. In order to maintain the slender shape requirement of the housing 100, the motor 200 and the pump mechanism 300 can be disposed sequentially along the first direction X. The motor 200 can be closer to the top 160 of the housing 100 (e.g., Figure 2 The motor 200 is positioned above the pump mechanism 300 , so that the output shaft 210 of the motor 200 passes through the top end 160 of the housing 100 and connects to a cleaning accessory 2000 (such as a toothbrush head, an integrated irrigating head, or other accessories with bristles) to drive the cleaning accessory 2000. The motor 200 can be a rotary motor 200 capable of rotating the cleaning accessory 2000; alternatively, the motor 200 can be a vibrating motor 200 (such as a sonic motor 200) capable of causing the cleaning accessory 2000 to oscillate at a high frequency. The motor 200 can include a motor body 220 and an output shaft 210. The axis of the output shaft 210 can coincide with the central axis of the housing 100 or be arranged parallel and spaced apart. The output shaft 210 can be axially inserted into the motor body 220. The axial top end 160 of the output shaft 210 can pass through the top end 160 of the motor body 220 and connect to the cleaning accessory 2000 to drive the cleaning accessory 2000.

[0067] The output shaft 210 may have a first flow channel 211 extending axially through the output shaft 210. The oral cleaning device provided in the embodiment of the present application may further include a built-in water tank, which may be formed in the inner cavity of the housing 100 and may have a liquid storage cavity 120 for storing liquid.

[0068] Figure 3 for Figure 2Another longitudinal section of the oral cleaning device is shown. Figure 2 and Figure 3 The support assembly may include a connector 400, and the connector 400 may have a second flow channel 410 and a third flow channel 420. It should be noted that the third flow channel 420 and the second flow channel 410 are not on the same longitudinal section. Figure 2 The cross section shown shows the second flow channel 410. Figure 3 The third flow channel 420 can be seen.

[0069] The third flow channel 420 can connect the liquid storage chamber 120 with the liquid inlet end 310 of the pump mechanism 300, and the second flow channel 410 can connect the liquid outlet end 320 of the pump mechanism 300 with the first flow channel 211. In this way, the second flow channel 410 and the third flow channel 420 are both integrated into the connector 400, which not only reduces the number of parts required for assembly and improves assembly efficiency, but also improves the overall structural strength of the second flow channel 410 and the third flow channel 420 to resist the impact force of the water flow. In addition, the connection stability between the liquid storage chamber 120 and the second flow channel 410, the second flow channel 410 and the pump mechanism 300, the pump mechanism 300 and the third flow channel 420, and the third flow channel 420 and the first flow channel 211 of the output shaft 210 is improved, thereby reducing the risk of leakage at the connection.

[0070] The first flow channel 211 of the output shaft 210 may be in communication with the outflow port 2300 through the cavity 2200 of the cleaning attachment 2000 . Figure 2 and Figure 3 The arrows in the figure indicate the direction of liquid flow. Figure 2 and Figure 3 As indicated by the arrows in the figure, when the oral cleaning device realizes the flushing function, the pump mechanism 300 can guide the liquid in the liquid storage cavity 120 into the pump cavity of the pump mechanism 300 through the third flow channel 420 and the liquid inlet end 310 of the pump mechanism 300, and then into the first flow channel 211 through the liquid outlet end 320 of the pump mechanism 300 and the second flow channel 410, and then flow out from the outflow port 2300 through the cavity 2200 of the cleaning attachment 2000.

[0071] refer to Figure 2 The power assembly (motor 200 and pump mechanism 300) and the liquid storage cavity 120 can be arranged in sequence along the first direction X (eg Figure 1 The power assembly is positioned above the liquid storage chamber 120, thereby shortening the longitudinal length of the liquid storage chamber 120 for easier cleaning of the water tank. The horizontal width of the housing 100 can also be reduced for easier gripping. The pump mechanism 300 can be positioned closer to the liquid storage chamber 120 than the motor 200, allowing the pump mechanism 300 to pump liquid from the liquid storage chamber 120.

[0072] In order to increase the longitudinal height of the liquid storage cavity 120 so as to increase the volume of the liquid storage cavity 120, refer to Figure 2 and Figure 3 Optionally, the liquid outlet end 320 of the pump mechanism 300 can output liquid along the second direction Y, and the liquid inlet end 310 and the liquid outlet end 320 of the pump mechanism 300 can be arranged on one side of the pump mechanism 300 along the second direction Y, wherein the second direction Y intersects with the first direction X. In this way, the length occupied by the pump mechanism 300 in the first direction X is shortened, the length of the liquid storage cavity 120 in the first direction X is increased, and the volume of the liquid storage cavity 120 is increased. Furthermore, the second direction Y is perpendicular to the first direction X. Figure 2 and Figure 3 In the figure, the first direction X is the up-down direction, the second direction Y is the left-right direction, and the liquid inlet end 310 and the liquid outlet end 320 of the pump mechanism 300 are both arranged on the left side of the pump mechanism 300 .

[0073] In order to effectively utilize the side space of the pump mechanism 300, further, the connecting member 400 can be connected to one side of the pump mechanism 300 along the second direction Y direction (such as Figure 2 and Figure 3 ), so that the third flow channel 420 and at least part of the second flow channel 410 are located on one side of the pump mechanism 300 along the second direction Y direction (such as Figure 2 and Figure 3 The connection between the connector 400 and the liquid storage chamber 120 may be located on one side of the pump mechanism 300 along the second direction Y (e.g., Figure 3 ), so as to shorten the distance between the liquid inlet end 310 of the pump mechanism 300 and the liquid storage cavity 120, so that the pump mechanism 300 can suck the liquid in the liquid storage cavity 120.

[0074] Furthermore, in the first direction X, the liquid inlet end 310 and the liquid outlet end 320 of the pump mechanism 300 can be closer to the liquid storage chamber 120. In other words, the liquid inlet end 310 and the liquid outlet end 320 of the pump mechanism 300 are disposed at an end of the pump mechanism 300 that is closer to the liquid storage chamber 120 along the first direction X. This shortens the distance between the liquid inlet end 310 of the pump mechanism 300 and the bottom of the liquid storage chamber 120, facilitating the pump mechanism 300 to pump liquid from the liquid storage chamber 120. Furthermore, the distance between the liquid outlet end 320 of the pump mechanism 300 and the first flow channel 211 is increased to reduce the impact force of the liquid at the liquid outlet end 320 of the pump mechanism 300 on the output shaft 210 of the motor 200, thereby facilitating connection stability.

[0075] The oral cleaning device 1000 provided in the embodiment of the present application may further include an energy component 710, which may be a rechargeable battery, a storage battery, or the like, capable of providing electrical energy to the motor 200, the pump mechanism 300, and the electrical components on the control panel 720. In order to keep the oral cleaning device 1000 slender, the energy component 710 may be located on a side of the pump mechanism 300 away from the motor 200 along the first direction X (e.g., Figure 2 and Figure 3 At least a portion of the energy component 710 is disposed side by side with at least a portion of the liquid storage cavity 120. In other words, a planar projection of at least a portion of the energy component 710 along the first direction X at least partially overlaps with a planar projection of the liquid storage cavity 120 along the first direction X. In other words, the energy component 710 and the liquid storage cavity 120 jointly occupy the bottom end 170 of the housing 100.

[0076] Figure 4 This is an internal layout diagram of the oral cleaning device provided in the embodiment of the present application. Figure 2-Figure 4 For example, the liquid storage cavity 120 may be wrapped around one side of the energy component 710 in the first axial direction. Figure 4 , the liquid storage cavity 120 can wrap the outer side surface and the bottom surface of the energy component 710. That is to say, in the first axial direction, the energy component 710 has a top surface and a bottom surface that are relatively set, and the housing 100 can have an inner top surface and an inner bottom surface that are relatively set; there is a gap between the bottom surface of the energy component 710 and the inner bottom surface of the housing 100, and at least part of the liquid storage cavity is located between the bottom surface of the energy component 710 and the inner bottom surface of the housing 100. In other words, the liquid storage cavity 120 can be shaped like a "concave", and the energy component 710 can be located in the depression of the concave liquid storage cavity 120. For another example, the liquid storage cavity 120 can only wrap the outer side surface of the energy component 710, that is, the bottom surface of the energy component 710 abuts against the inner bottom surface of the housing 100. In other words, at least a part of the end of the energy component 710 extending along the first direction X is wrapped by the liquid storage cavity 120.

[0077] Figure 5 Another internal layout diagram of the oral cleaning device provided in the embodiment of the present application. Figure 5 In another exemplary embodiment, a space for placing the energy component 710 is formed between the liquid storage cavity 120 and the inner shell wall of the housing 100. In other words, a space for placing the energy component 710 is formed between the partition 600 and the inner shell wall of the housing 100. For example, Figure 5In the embodiment, the liquid storage cavity 120 can cover the bottom surface of the energy component 710 and at least a portion of the outer surface of the energy component 710. In other words, there is a gap between the bottom surface of the energy component 710 and the inner bottom surface of the housing 100, and at least a portion of the liquid storage cavity is located between the bottom surface of the energy component 710 and the inner bottom surface of the housing 100. In other words, the liquid storage cavity 120 can be L-shaped, and the energy component 710 can be located in the gap of the L-shaped liquid storage cavity 120. For another example, the liquid storage cavity 120 can only cover the outer surface of the energy component 710, that is, the bottom surface of the energy component 710 abuts the inner bottom surface of the housing 100.

[0078] The liquid storage cavity 120 may be formed by a housing 130 independent of the housing 100, and the liquid storage cavity 120 may be detachably connected to the housing 100 so that the user can remove the liquid storage cavity 120 from the housing 100 for cleaning. Alternatively, the liquid storage cavity 120 may be formed by the inner wall of the housing 100 and the partition 600. Figure 4 and Figure 5 The oral cleaning device 1000 provided in the embodiment of the present application may further include a partition 600, which may be disposed in the inner cavity of the housing 100 and may separate the inner cavity of the housing 100 into a power cavity 110 and a liquid storage cavity 120. The motor 200, the pump mechanism 300, and the energy element 710 may all be disposed in the power cavity 110.

[0079] like Figure 4 and Figure 5 In the embodiment, the separator 600 and the separator 600 are located on one side of the separator 600 along the first direction X (such as Figure 4 and Figure 5 The inner shell wall of the casing 100 on the left side of the casing 100 can be enclosed to form a power cavity 110, and the partition 600 and the partition 600 on the other side along the first direction X (such as Figure 4 and Figure 5 The inner shell wall of the casing 100 on the right side of the casing 100 can be enclosed to form a liquid storage cavity 120.

[0080] Exemplary, reference Figure 3 and Figure 6, the partition 600 is detachably connected to the casing 100 so that the user can remove the partition 600 from the casing 100 for cleaning. Taking into account the sealing performance, a first seal 810 may be filled between the partition 600 and the casing 100. For example, the outer wall of the partition 600 may be provided with a first sealing groove, and a first sealing cavity may be formed between the first sealing groove and the inner shell wall of the casing 100. The first seal 810 may be a first sealing ring, which may be sealed in the first sealing cavity to prevent liquid from leaking. In addition, the partition 600 and the casing 100 may be detachably connected by a snap connection; and / or, the partition 600 and the connecting member 400 (or the mounting member 500 mentioned below) are fastened together by fasteners such as bolts. Furthermore, the fastener connection may be waterproofed. For example, refer to Figure 7 The partition 600 may have a blind hole, the connector 400 or the mounting member 500 may have a threaded hole, and the first fastener 921 may be passed through the blind hole of the partition 600 and threadedly connected to the threaded hole provided in the connector 400 or the mounting member 500.

[0081] In another exemplary embodiment, the partition 600 and the housing 100 may be an integral piece formed by an integral molding process to facilitate assembly and improve connection strength.

[0082] Figure 6 for Figure 3 A cross-sectional view of the separator 600 is shown. Figure 3 and Figure 6 In order to connect the liquid inlet end 310 of the pump mechanism 300 disposed in the power cavity 110 with the liquid storage cavity 120, the partition 600 may have a connecting hole 680 connecting the power cavity 110 and the liquid storage cavity 120, and the third flow channel 420 of the connecting member 400 may be connected with the liquid storage cavity 120 through the connecting hole 680. In order to shorten the distance between the liquid inlet end 310 of the pump mechanism 300 and the liquid storage cavity 120, the connecting hole 680 may be optionally provided on one side of the pump mechanism 300 along the second direction Y (e.g., Figure 3 on the left side of the ).

[0083] To prevent liquid leakage, the connecting member 400 and the communicating hole 680 may optionally be sealed by a second sealing member 820. Specifically, the outer wall of the connecting member 400 may have a second sealing groove, and a second sealed cavity may be formed between the second sealing groove and the inner wall of the communicating hole 680.

[0084] The partition 600 may be formed with an accommodating opening 620 and an accommodating cavity 610 for accommodating the energy component 710. The accommodating opening 620 may be arranged on one side of the accommodating cavity 610 along the first direction X toward the pump mechanism 300 (eg, Figure 3 and Figure 6 The separator 600 may be as follows. Figure 2-Figure 4 、 Figure 6 As shown in FIG. 6 , the receiving port 620 and the receiving cavity 610 can be formed separately. Alternatively, the partition 600 can be formed as shown in FIG.

[0085] In one possible structure of the separator 600, reference Figure 2-Figure 4 、 Figure 6 When the liquid storage cavity 120 wraps around one side of the energy component 710 along the first direction X, the partition 600 may include a first portion 630 and a second portion 640 that are sequentially connected along the first direction X, with the first portion 630 being closer to the pump mechanism 300 than the second portion 640. The inner sidewall of the first portion 630 may form the accommodating opening 620 and a portion of the accommodating cavity 610, while the inner sidewall of the second portion 640 may form another portion of the accommodating cavity 610. The outer sidewall of the first portion 630 may be shaped to match the shape of the inner wall of the housing 100, and the outer sidewall of the first portion 630 abuts the inner wall of the housing 100. The first portion 630 may be formed with a communication hole 680. The outer sidewall of the second portion 640 and the inner wall of the housing 100 may define at least a portion of the liquid storage cavity 120.

[0086] For example, the liquid storage cavity 120 may be provided with a fourth flow channel 651 connecting the bottom of the liquid storage cavity 120 and the connecting hole 680. The fourth flow channel 651 may be formed by an independent tube. Alternatively, the fourth flow channel 651 may be formed by a separator 600 to facilitate assembly and improve the connection strength between the fourth flow channel 651 and the connecting hole 680. Figure 3 The partition 600 may further include a third portion 650, which is integrally connected to the first portion 630. The third portion 650 may have a fourth flow channel 651 for liquid flow. The fourth flow channel 651 may connect the communication hole 680 with the side of the liquid storage chamber 120 away from the pump mechanism 300. Furthermore, the fourth flow channel 651 may extend along the first direction X to reduce the length of the water path between the liquid inlet end 310 of the pump mechanism 300 and the side of the liquid storage chamber 120 away from the pump mechanism 300.

[0087] In another possible structure of the separator 600, refer to Figure 5When a space for accommodating the energy component 710 is formed between the liquid storage cavity 120 and the inner wall of the housing 100 , the partition 600 may include a fourth portion 660 , which may extend along the first direction X.

[0088] Furthermore, the partition 600 may further include a fifth portion 670 , which may be connected between the fourth portion 660 and the inner shell wall of the housing 100 , and the fifth portion 670 may provide support in the first direction X for the energy component 710 .

[0089] Figure 7 This is an exploded view of the oral cleaning device provided in the embodiment of the present application. Figure 7 The oral cleaning device provided in the embodiment of the present application may further include a mounting member 500. To facilitate assembly, the mounting member 500 is fixed to the inner wall of the housing 100, and both the motor 200 and the pump mechanism 300 can be mounted on the mounting member 500. Thus, during assembly, the motor 200 and the pump mechanism 300 can be first mounted on the mounting member 500, and then the two can be installed as a single assembly into the housing 100.

[0090] It should be noted that both the motor 200 and the pump mechanism 300 generate vibrations during operation, resulting in poor connection reliability of the pipeline connecting the liquid outlet 320 of the pump mechanism 300 and the first flow channel 211 of the output shaft 210, which is extremely prone to falling off. To address the above problem, the inventors of this application conceived of disassembling the pump mechanism 300 into a power end 330, a liquid inlet end 310, and a liquid outlet end 320, and integrating the liquid outlet end 320 with the connector 400 and the mounting member 500 to reduce resonance and improve the connection reliability at the connection point between the second flow channel 410 of the connector 400 and the liquid outlet 320 of the pump mechanism 300.

[0091] Specifically, refer to Figures 8-11The second valve portion 321 of the liquid outlet end 320 can be integrated into the mounting member 500, and the second end cap portion 322 of the liquid outlet end 320 can be integrated into the connector 400. The power end 330, at least a portion of the connector 400, and at least a portion of the mounting member 500 can be sequentially arranged along the liquid outlet direction (second direction Y) of the liquid outlet end 320 and connected via a third fastener 923. In this manner, the mounting member 500 is interposed between the connector 400 and the power end 330 of the pump mechanism 300, thereby transmitting most of the vibration of the pump body to the mounting member 500. A vibration damper may be provided between the mounting member 500 and the inner wall of the housing 100. The mounting member 500 can eliminate vibrations through the vibration-damping connection, thereby minimizing or eliminating the vibrations transmitted from the power end 330 of the pump mechanism 300 to the connector 400. This reduces the impact of the vibrations of the power end 330 of the pump mechanism 300 on the connector 400, thereby improving the reliability of the connection between the second flow channel 410 of the connector 400 and the liquid outlet 320 of the pump mechanism 300. Furthermore, integrating the liquid outlet 320 into the mounting member 500 and the connector 400 not only facilitates assembly, but also shortens the waterway and enhances connection reliability.

[0092] Optionally, the power end 330 may include a pump housing 331 and a piston 332, with one end of the pump housing 331 having an opening. The mounting member 500 may seal the opening, and the mounting member 500 and the pump housing 331 may together form a pump chamber of the pump mechanism 300, which allows the piston 332 to reciprocate along the liquid discharge direction of the liquid discharge end 320. The mounting member 500 may have a liquid outlet hole extending through the mounting member 500 and communicating with the pump chamber of the pump mechanism 300. The second valve portion 321 of the liquid discharge end 320 is disposed in the liquid outlet hole. The second valve portion 321 of the liquid discharge end 320 may allow liquid to be pumped out of the pump chamber through the liquid outlet hole, while preventing liquid from flowing into the pump chamber through the liquid outlet hole.

[0093] Specifically, piston 332 reciprocates within the pump chamber, pumping liquid out of the chamber through the outlet port. The valve at outlet port 320 provides a one-way flow to prevent liquid from flowing back into the pump chamber through the outlet port. In this embodiment, mounting member 500 forms the pump chamber and outlet port, integrating the valve portion of outlet port 320.

[0094] Optional, reference Figure 11 The power end 330 may further include a driving member 333, which may have a driving shaft that rotates relative to the pump housing 331. The driving shaft may drive the eccentric wheel to rotate relative to the pump housing 331, and the eccentric wheel may push against the piston 332 to perform reciprocating motion.

[0095] refer to Figure 10-12Optionally, at least a portion of the connector 400 and the second end cap portion 322 of the liquid outlet 320 may be formed as an integral piece using an integral molding process. Furthermore, the second end cap portion 322 of the liquid outlet 320 may cover the liquid outlet hole, and may form a liquid outlet channel connecting the liquid outlet hole and the second flow channel 410.

[0096] Specifically, the liquid outlet channel of the second end cap portion 322 of the liquid outlet end 320 can guide the flow direction of the liquid flowing out of the liquid outlet hole. In this solution, the connector 400 and the second end cap portion 322 of the liquid outlet end 320 are integrated into one piece, so that the liquid outlet channel and the second flow channel 410 are integrated, which helps to improve the connection reliability of the connection point, improve the smoothness of liquid flow, and improve the convenience of assembly.

[0097] Optionally, the mounting member 500 may have a liquid inlet hole extending through the mounting member 500 and communicating with the pump chamber of the pump mechanism 300. The first valve portion 311 of the liquid inlet end 310 may be disposed at the liquid inlet hole, and the first valve portion 311 of the liquid inlet end 310 may allow liquid to be pumped into the pump chamber through the liquid inlet hole, while preventing liquid from flowing out through the liquid inlet hole.

[0098] Specifically, the reciprocating motion of piston 332 within the pump chamber allows liquid to be pumped into the pump chamber through the liquid inlet. The valve at liquid inlet end 310 provides a one-way flow to prevent liquid from escaping through the liquid inlet. In this embodiment, the pump chamber and the liquid inlet are formed using mounting member 500, thereby integrating the first valve portion 311 of liquid inlet end 310.

[0099] Optionally, at least a portion of the connector 400 and the first end cap portion 312 of the liquid inlet end 310 can be formed as an integral piece using an integral molding process, and the first end cap portion 312 of the liquid inlet end 310 can cover the liquid inlet hole, and the first end cap portion 312 of the liquid inlet end 310 can be formed with a liquid inlet channel connected to the liquid inlet hole, and the liquid inlet channel can be connected to the third channel 420 of the connector 400. In this way, the liquid inlet channel of the first end cap portion 312 of the liquid inlet end 310 can guide the flow direction of the liquid flowing into the liquid inlet hole. In this solution, the connector 400 and the first end cap portion 312 of the liquid inlet end 310 are integrated into one piece, so that the liquid inlet channel and the third channel 420 are integrated, which helps to improve the connection reliability of the connection point, helps to improve the smoothness of liquid flow, and helps to improve the convenience of assembly.

[0100] refer to Figures 8-11Optionally, the mounting member 500 may include a first mounting portion 510 having a first side and a second side disposed opposite each other along the liquid outlet direction of the liquid outlet end 320. The motor 200 and the power end 330 of the pump mechanism 300 may be spaced apart along the axial direction of the output shaft 210 on the first side of the first mounting portion 510. The portion of the connector 400 incorporating the second end cap portion 322 of the liquid outlet end 320 may be disposed on the second side of the first mounting portion 510. The mounting member 500 may have a through hole 530 for the connector 400 to pass through and constrain the connector 400 on at least one side along the axial direction of the output shaft 210. This through hole 530 can be used to constrain the connector 400, providing upward support and limiting position, thereby preventing vertical vibration. Optionally, the control board 720 may be mounted on the side of the first mounting portion 510 facing away from the motor 200 using a fourth fastener 924. A fourth vibration damper 914 may be disposed between the control board 720 and the inner wall of the housing 100 .

[0101] refer to Figure 7 and Figure 8 Optionally, the mounting member 500 may further include a second mounting portion 520, which may be mateably connected to the first side of the first mounting portion 510, and the second mounting portion 520 and the first mounting portion 510 may be enclosed to form a receiving space for wrapping the outer side surface of the motor 200. In this way, the mounting member 500 is wrapped around the outer side surface of the motor 200, so that most of the vibration of the motor 200 is transmitted to the mounting member 500, thereby making it possible to achieve little or no vibration transmitted from the electric energy transmission machine 200 to the connecting member 400. In this way, the influence of the vibration of the power end 330 of the motor 200 on the connecting member 400 is reduced, and the connection reliability of the connection point between the second flow channel 410 of the connecting member 400 and the first flow channel 211 of the motor 200 is improved. Optionally, refer to Figure 8 The first mounting portion 510 and the second mounting portion 520 can be fastened together by a second fastener 922 .

[0102] Optionally, a vibration damper is sandwiched between the first mounting portion 510 and the outer side of the motor 200; and / or a vibration damper is sandwiched between the second mounting portion 520 and the outer side of the motor 200. In this way, the vibration damper can reduce the vibration transmission between the motor 200 and the mounting portion 500. For example, Figure 8 In the embodiment, the second vibration damper 912 is sandwiched between the front end of the motor 200 and the mounting member 500 , and the third vibration damper 913 is sandwiched between the rear end of the motor 200 and the mounting member 500 .

[0103] refer to Figure 12Optionally, the connector 400 may have a mounting groove 450 into which the output shaft 210 of the power supply 200 passes, and a fourth seal 840 may be placed between the inner wall of the mounting groove 450 and the output shaft 210 of the motor 200. Specifically, the first flow channel 211 of the output shaft 210 and the second flow channel 410 of the connector 400 may communicate at the mounting groove 450. The provision of a seal can prevent liquid leakage at the connection point.

[0104] Continue to refer Figure 12 Optionally, the motor 200 may include a motor body 220 and an output shaft 210. The output shaft 210 of the motor 200 may be inserted into the motor body 220, and both axial ends of the output shaft 210 may pass through the motor body 220. The bottom surface of the motor body 220 and the inner groove wall of the mounting groove 450 may be combined to form a restricted space for restricting the fourth seal 840. The restricted space may restrict both ends of the fourth seal 840 in the axial direction of the output shaft 210. In this way, the bottom surface of the motor body 220 of the motor 200 and the bottom wall of the mounting groove 450 may be used to restrict the fourth seal 840 to prevent the fourth seal 840 from moving due to vibration.

[0105] refer to Figure 12 The second flow channel 410 may include a first flow segment 411 and a second flow segment 412 that are sequentially connected. The first flow segment 411 is connected to the liquid outlet 320 and may extend along the first direction X. A distance is provided between the first flow segment 411 and the first flow channel 211 along the second axis. The second flow segment 412 may connect the first flow segment 411 and the first flow channel 211 and may include a first arc segment 4121. The first arc segment 4121 may form an arc transition with the first flow segment 411. The arc transition reduces the resistance of the flow channel inner wall to the liquid, thereby facilitating liquid flow.

[0106] Furthermore, the first arc segment 4121 may be higher than the pump mechanism 300 and may have an arc center facing the pump mechanism 300 so that the liquid flows more smoothly toward the first flow channel 211 to further reduce the resistance of the flow channel inner wall to the liquid.

[0107] Optionally, the second flow section 412 further includes a second arc section 4122, and a circular arc transition is formed between the second arc section 4122 and the first flow channel 211. The circular arc transition is used to reduce the resistance of the flow channel inner wall to the liquid, thereby facilitating the flow of the liquid.

[0108] Furthermore, the second arc segment 4122 has an arc center facing the motor 200 , so that the second arc segment 4122 smoothly borders the first flow channel 211 , which is beneficial to the flow of liquid.

[0109] refer to Figure 12 and Figure 13Optionally, the connector 400 may include a first connecting portion 430 and a second connecting portion 440 connected to each other. The first connecting portion 430 may include a first flow segment 411 and a reversing cavity 431 communicating with the first flow segment 411. The reversing cavity 431 may have a first inner curved surface 432 and an opening in the first direction X. At least a portion of the second connecting portion 440 may be embedded in the reversing cavity 431 through the opening of the reversing cavity 431 and may have a second inner curved surface 441. The first inner curved surface 432 and the second inner curved surface 441 may together form the second flow segment 412.

[0110] Specifically, the second connecting portion 440 may include a cover section 442, a raised section 443, and a baffle section 444. The raised section 443 and the baffle section 444 may be respectively connected to either side of the cover section 442 along the first direction X. The cover section 442 may cover the reversing cavity 431, and the baffle section 444 may be located within the reversing cavity 431 and may have a second inner curved surface 441. The cover section 442 may be provided with a through hole, the raised section 443 may surround the outside of the through hole, and the inner cavity of the raised section 443 may be in communication with the through hole. The output shaft 210 may be inserted into the inner cavity of the raised section 443 and the through hole, and a fourth sealing member 840 may be provided between the output shaft 210 and the inner cavity wall of the raised section 443. In this manner, the raised section 443 and a portion of the cover section 442 may form the mounting groove 450 mentioned above.

[0111] refer to Figure 8 and Figure 14 The power assembly (motor 200, pump mechanism 300) and the charging receiving assembly 730 can all be assembled on the mounting member 500, so that the mounting member 500, the power assembly, and the charging receiving assembly 730 can be assembled as an integral module in the inner cavity of the housing 100, thereby achieving modular assembly and improving assembly efficiency. In addition, the charging receiving assembly 730 can be arranged on one side of the mounting member 500 along the second direction Y, so that the charging receiving assembly 730 can face the inner wall of one side of the housing 100 and cooperate with the charging transmitting assembly 3000 outside the housing 100. Furthermore, the control panel 720 can be arranged on the other side of the mounting member 500 along the second direction Y, so that the control panel 720 can face the inner wall of the other side of the housing 100 and cooperate with the buttons arranged on this side.

[0112] It is worth noting that the oral cleaning device provided in the embodiment of the present application is generally placed in a relatively humid place such as a bathroom. If an exposed charging port is provided on the device housing 100, external moisture will contaminate the charging port, affecting the use of the device. In view of this, the oral cleaning device provided in the embodiment of the present application adopts a wireless charging method to avoid installing an opening on the device housing 100 to install the charging port, thereby improving charging safety and preventing water from entering the opening and damaging the internal components of the housing.

[0113] refer to Figure 14 and Figure 15 The charging receiving assembly 730 may include a charging receiving member 731 and a first magnet 732. The charging receiving member 731 may cooperate with the charging transmitting assembly 3000 to achieve power transfer. The first magnet 732 may be disposed on the periphery of the charging receiving member 731, and a distance may be provided between the first magnet 732 and the charging receiving member 731 to prevent the first magnet 732 from affecting the charging receiving member 731. In addition, the first magnet 732 may magnetically cooperate with the charging transmitting assembly 3000.

[0114] Exemplary, reference Figure 1 Figure 14 as well as Figure 16 The charging transmitter assembly 3000 may include a circuit board 3200 with multiple electrical components, at least one of which may electrically connect the charging transmitter 3300 to a power cord, allowing external electrical energy to be transmitted to the charging transmitter 3300 via the power cord. The second magnet 3400 may be disposed on the periphery of the charging transmitter 3300, with a distance between the second magnet 3400 and the charging transmitter 3300 to prevent it from interfering with the charging transmitter 3300. During charging, the magnetic attraction between the first magnet 732 and the second magnet 3400 may be utilized to connect the charging transmitter assembly to the oral cleaning device 1000.

[0115] Furthermore, there may be multiple first magnets 732, and at least two of the multiple first magnets 732 may be spaced apart along the first direction X to prevent the charging transmitter assembly 3000 from sliding due to gravity when the device is placed vertically on a table or other location for charging along the first direction X. Similarly, there may be multiple second magnets 3400, and at least two of the multiple second magnets 3400 may be spaced apart along the first direction X.

[0116] The charging transmitter 3300 and the charging receiver 731 can be configured in the following two ways:

[0117] In one possible configuration of the charging transmitter 3300 and the charging receiver 731, the charging transmitter 3300 can be a first coil that generates a magnetic field based on the electrical energy provided by the power cord. The charging receiver 731 can be a second coil that can be spaced apart from the first coil along its axis. The second coil can sense the magnetic field generated by the first coil and generate electrical energy. In this way, the charging transmitter 3300 and the charging receiver 731 can be coupled using the principle of electromagnetic induction to generate energy exchange.

[0118] Specifically, the first coil can be connected in series within a closed loop containing the power cord and can generate a varying magnetic field when the closed loop is energized. To increase the strength of the varying magnetic field generated by the first coil when energized, the first coil can be formed by winding a linear wire along a specific linear direction. The number of turns of the first coil is the same as the number of turns of the wire. The first coil has multiple turns, each of which generates a magnetic field when energized. These magnetic fields can be superimposed to enhance the field strength of the first coil.

[0119] Alternatively, a second coil can be connected in series within the closed loop of energy element 710. When the magnetic flux passing through the second coil changes, it generates an induced current that powers energy element 710. To induce the change in magnetic flux and generate the induced current, specifically, an alternating current is passed through the first coil, causing the first coil to generate an alternating magnetic field, at least a portion of which passes through the second coil. As the current in the first coil changes over time, the magnetic flux passing through the second coil also changes, causing the second coil to generate an induced current.

[0120] In another possible configuration of the charging transmitter 3300 and the charging receiver 731, the charging transmitter 3300 can be a third coil, and this third coil is a self-oscillating system. An oscillator can be connected in series between the power supply and the third coil. This oscillator can output a high-frequency oscillating current to the third coil, which receives the high-frequency oscillating current and emits electromagnetic waves, forming a non-radiative magnetic field around the third coil. In this way, the third coil can convert the electrical energy from the power supply into a magnetic field.

[0121] Alternatively, the charging receiver 731 may be a fourth coil, and this fourth coil may have a natural frequency. When the natural frequency of the fourth coil matches the frequency of the electromagnetic waves emitted by the third coil, the fourth coil generates a strong oscillating current. In this way, the fourth coil can convert the magnetic field into electrical energy.

[0122] refer to Figure 14 and Figure 15 Optionally, the mounting member has a positioning groove for accommodating the charging receiving assembly, and the positioning groove has an opening facing away from the accommodating space. In this way, the positioning groove is used to limit the position of the charging receiving assembly and enable rapid positioning and assembly between the charging receiving assembly and the mounting member.
