DETAILED DESCRIPTION

[0052] Fig. 1 is a schematic view of an oral cleaning device according to an embodiment of the present application, and Fig. 2 is a longitudinal sectional view of the oral cleaning device shown in Fig. 1. Referring to Figs. 1 and 2, the oral cleaning device according to an embodiment of the present application can include an oral cleaning device 1000 and a cleaning accessory 2000, wherein the cleaning accessory 2000 can be a toothbrush head, a rinsing head, a brushing and rinsing integrated head, or the like.

[0053] The specific structure of the oral cleaning device 1000 provided by the embodiments of the present application will be described below by taking the cleaning accessory 2000 as an example. Specifically, the cleaning accessory 2000 can include a brush body 2100, and the brush body 2100 can have a cavity 2200 and a flow outlet 2300 in communication with the cavity 2200.

[0054] With continuous reference to FIG. 2, the oral cleaning device 1000 can include a housing 100, a power assembly, a charging receiving assembly, and a support assembly. In order to facilitate the user to hold, the housing 100 can be shaped like an elongated cylinder. The cross-sectional shape of the housing 100 can be circular or non-circular (such as D-shaped, oval, polygonal, etc.). The housing 100 can extend along a first direction X (such as the up-down direction in FIG. 2), and the housing 100 can have a top end 160 and a bottom end 170 oppositely arranged in the first direction X. The interior of the housing 100 can be hollow to form an inner cavity of the housing 100.

[0055] The power assembly can be arranged 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 shape requirement of the elongated housing 100, the motor 200 and the pump mechanism 300 can be arranged in sequence along the first direction X. The motor 200 can be closer to the top end 160 of the housing 100 than the pump mechanism 300 (such as the motor 200 is located above the pump mechanism 300 in FIG. 2), so that the output shaft 210 of the motor 200 can pass through the top end 160 of the housing 100 and be connected with the cleaning accessory 2000 (such as a toothbrush head, a flush integrated head, etc. having bristles) to drive the cleaning accessory 2000 to move. The motor 200 can be a rotating motor 200 capable of rotating the cleaning accessory 2000; or the motor 200 can be a vibrating motor 200 (such as a sonic motor 200, etc.) capable of high-frequency oscillating the cleaning accessory 2000. The motor 200 can include a motor body 220 and an output shaft 210. The axis of the output shaft 210 can coincide with or be arranged in parallel and spaced apart with the central axis of the housing 100. The output shaft 210 can pass through the motor body 220 along the axial direction thereof. The top end 160 of the output shaft 210 in the axial direction can pass through the top end 160 of the motor body 220 and can be connected with the cleaning accessory 2000 to drive the cleaning accessory 2000 to move.

[0056] The output shaft 210 can have a first flow channel 211 penetrating the output shaft 210 along the axial direction thereof. The oral cleaning device provided by the embodiments of the present application can further include an internal water tank, which can be formed in the inner cavity of the housing 100, and the water tank can have a liquid storage cavity 120 for storing liquid.

[0057] Figure 3 is another partial view of the oral cleaning device shown in Figure 2, in longitudinal section. Referring to Figures 2 and 3, the support assembly can include a connector 400, which can 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 in the same longitudinal section, so that the second flow channel 410 can be seen from the section shown in Figure 2, and the third flow channel 420 can be seen from Figure 3.

[0058] The third flow channel 420 can communicate the liquid storage cavity 120 with the liquid inlet end 310 of the pump mechanism 300, and the second flow channel 410 can communicate 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 on the connector 400, which not only reduces the number of parts needed to be assembled to improve 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, thereby improving the connection stability between the liquid storage cavity 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, to reduce the risk of liquid leakage at the connection.

[0059] The first flow channel 211 of the output shaft 210 can be communicated with the cavity 2200 and the flow outlet 2300 of the cleaning accessory 2000. The arrows in Figures 2 and 3 represent the direction of liquid flow, and referring to the arrow marks in Figures 2 and 3, when the oral cleaning device implements the rinsing function, the pump mechanism 300 can guide the liquid in the liquid storage cavity 120 to enter the pump cavity of the pump mechanism 300 through the third flow channel 420, the liquid inlet end 310 of the pump mechanism 300, then enter the first flow channel 211 through the liquid outlet end 320 of the pump mechanism 300, the second flow channel 410, and then flow out from the flow outlet 2300 through the cavity 2200 of the cleaning accessory 2000.

[0060] Referring 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 (e.g., the power assembly is located above the liquid storage cavity 120 in Figure 1), so as to shorten the longitudinal length of the liquid storage cavity 120, facilitating the user to clean the water tank, and also to reduce the transverse width of the housing 100, facilitating the user to hold. Among them, the pump mechanism 300 can be closer to the liquid storage cavity 120 than the motor 200, so as to facilitate the pump mechanism 300 to suck liquid from the liquid storage cavity 120.

[0061] To increase the longitudinal height of the liquid storage cavity 120 so as to increase the volume of the liquid storage cavity 120, with reference to FIG. 2 and FIG. 3, the liquid outlet end 320 of the pump mechanism 300 can output liquid in a 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 in the second direction Y, wherein the second direction Y intersects the first direction X. In this way, the length of the pump mechanism 300 in the first direction X is shortened, and the length of the liquid storage cavity 120 in the first direction X is increased, thereby increasing the volume of the liquid storage cavity 120. Further, the second direction Y is perpendicular to the first direction X. As shown in FIG. 2 and FIG. 3, the first direction X is the up-down direction, and the second direction Y is the left-right direction. The liquid inlet end 310 and the liquid outlet end 320 of the pump mechanism 300 are arranged on the left side of the pump mechanism 300.

[0062] To effectively utilize the side space of the pump mechanism 300, further, the connecting member 400 can be connected to one side (e.g., the left side in FIG. 2 and FIG. 3) of the pump mechanism 300 in the second direction Y, so that the third flow channel 420 and at least part of the second flow channel 410 are located on one side (e.g., the left side in FIG. 2 and FIG. 3) of the pump mechanism 300 in the second direction Y. The connection between the connecting member 400 and the liquid storage cavity 120 can be located on one side (e.g., the left side in FIG. 3) of the pump mechanism 300 in the second direction Y, so as to shorten the distance between the liquid inlet end 310 of the pump mechanism 300 and the liquid storage cavity 120, thereby facilitating the pump mechanism 300 to suck liquid in the liquid storage cavity 120.

[0063] Further, 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 cavity 120. That is, the liquid inlet end 310 and the liquid outlet end 320 of the pump mechanism 300 are arranged on the end of the pump mechanism 300 closer to the liquid storage cavity 120 in the first direction X. In this way, the distance between the liquid inlet end 310 of the pump mechanism 300 and the bottom of the liquid storage cavity 120 is shortened, thereby facilitating the pump mechanism 300 to suck liquid in the liquid storage cavity 120; and the distance between the liquid outlet end 320 of the pump mechanism 300 and the first flow channel 211 is increased, thereby reducing 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.

[0064] The oral cleaning device 1000 provided by the embodiments of the present application can further comprise an energy source 710, which can be a rechargeable battery, a storage battery or the like, and can provide electric energy for the motor 200, the pump mechanism 300 and the electrical devices on the control board 720. In order to enable the oral cleaning device 1000 to maintain an elongated shape, the energy source 710 can be located on the side of the pump mechanism 300 away from the motor 200 in the first direction X (for example, the lower side in FIGS. 2 and 3). At least part of the energy source 710 is arranged side by side with at least part of the liquid storage cavity 120, in other words, at least part of the energy source 710 overlaps at least part of the liquid storage cavity 120 in the planar projection of the energy source 710 in the first direction X. That is, the energy source 710 and the liquid storage cavity 120 jointly occupy the bottom end 170 of the casing 100.

[0065] FIG. 4 is a schematic diagram of an internal layout of an oral cleaning device provided by the embodiments of the present application. Referring to FIGS. 2-4, the liquid storage cavity 120 can wrap around one side of the energy source 710 in the first axial direction. For example, in FIG. 4, the liquid storage cavity 120 can wrap around the outer side and the bottom of the energy source 710. That is, in the first axial direction, the energy source 710 has oppositely arranged top and bottom surfaces, and the casing 100 can have oppositely arranged inner top and bottom surfaces; the bottom surface of the energy source 710 and the inner bottom surface of the casing 100 have a spacing therebetween, and at least part of the liquid storage cavity is located between the bottom surface of the energy source 710 and the inner bottom surface of the casing 100. In other words, the liquid storage cavity 120 can have a concave shape, and the energy source 710 can be located in the concave of the concave-shaped liquid storage cavity 120. For another example, the liquid storage cavity 120 can wrap around only the outer side of the energy source 710, that is, the bottom surface of the energy source 710 and the inner bottom surface of the casing 100 are in abutment. In still another way of expression, one end of the energy source 710 extending in the first direction X is at least partially wrapped by the liquid storage cavity 120.

[0066] FIG. 5 is another schematic diagram of an internal layout of an oral cleaning device provided by the embodiments of the present application. Referring to FIG. 5, the liquid storage cavity 120 and the inner casing wall of the casing 100 form a space for placing the energy source 710. In other words, the space for placing the energy source 710 is formed between the partition 600 and the inner casing wall of the casing 100. For example, in FIG. 5, the liquid storage cavity 120 can wrap around the bottom of the energy source 710 and at least part of the outer side of the energy source 710. That is, the bottom surface of the energy source 710 and the inner bottom surface of the casing 100 have a spacing therebetween, and at least part of the liquid storage cavity is located between the bottom surface of the energy source 710 and the inner bottom surface of the casing 100. In other words, the liquid storage cavity 120 can have an L shape, and the energy source 710 can be located at the notch of the L-shaped liquid storage cavity 120. For another example, the liquid storage cavity 120 can wrap around only the outer side of the energy source 710, that is, the bottom surface of the energy source 710 and the inner bottom surface of the casing 100 are in abutment.

[0067] The liquid storage cavity 120 can be formed by a housing 130 independent of the casing 100, and the liquid storage cavity 120 can be detachably connected to the casing 100 so that a user can detach the liquid storage cavity 120 from the casing 100 for cleaning. Alternatively, the liquid storage cavity 120 can be formed by the inner casing wall of the casing 100 and the partition 600. Specifically, referring to FIGS. 4 and 5, the oral cleaning device 1000 provided by the embodiments of the present application can further include a partition 600, which can be arranged in the inner cavity of the casing 100 and can divide the inner cavity of the casing 100 into the power cavity 110 and the liquid storage cavity 120. The motor 200, the pump mechanism 300, and the energy source 710 can be arranged in the power cavity 110.

[0068] As shown in FIGS. 4 and 5, the partition 600 and the inner casing wall of the casing 100 on one side of the partition 600 along the first direction X (e.g., the left side in FIGS. 4 and 5) can enclose the power cavity 110, and the partition 600 and the inner casing wall of the casing 100 on the other side of the partition 600 along the first direction X (e.g., the right side in FIGS. 4 and 5) can enclose the liquid storage cavity 120.

[0069] For example, referring to FIGS. 3 and 6, the partition 600 can be detachably connected to the casing 100 so that a user can detach the partition 600 from the casing 100 for cleaning. In consideration of sealing, the partition 600 and the casing 100 can be filled with a first sealing member 810. For example, the outer side wall of the partition 600 can be provided with a first sealing groove, a first sealing cavity can be formed between the first sealing groove and the inner casing wall of the casing 100, and the first sealing member 810 can be a first sealing ring, which can be sealed in the first sealing cavity to prevent liquid from leaking out. In addition, the partition 600 and the casing 100 can be detachably connected by snap connection, and / or the partition 600 and the connecting member 400 (or the mounting member 500 to be mentioned below) can be fastened by fasteners such as bolts. Further, the fastener connection can be waterproofed. For example, referring to FIG. 7, the partition 600 can have a blind hole, the connecting member 400 or the mounting member 500 can be provided with a threaded hole, and a first fastener 921 can be arranged in the blind hole of the partition 600 and screwed with the threaded hole of the connecting member 400 or the mounting member 500.

[0070] Alternatively, the partition 600 and the casing 100 can be an integral piece formed by an integral molding process to facilitate assembly and improve connection strength.

[0071] FIG. 6 is a sectional view of the partition 600 shown in FIG. 3. Referring to FIGS. 3 and 6, in order to make the liquid inlet end 310 of the pump mechanism 300 disposed in the power cavity 110 communicate with the liquid storage cavity 120, the partition 600 can have a communication hole 680 that communicates the power cavity 110 with the liquid storage cavity 120, and the third flow passage 420 of the connecting member 400 can communicate with the liquid storage cavity 120 through the communication 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, optionally, the communication hole 680 can be disposed at one side of the pump mechanism 300 along the second direction Y (e.g., the left side in FIG. 3).

[0072] In order to avoid liquid leakage, optionally, the connecting member 400 and the communication hole 680 can be sealingly connected by a second sealing member 820.

[0078] FIG. 7 is an exploded view of the oral cleaning device according to an embodiment of the present application. Referring to FIG. 7, the oral cleaning device according to an embodiment of the present application can further include a mounting member 500. To facilitate assembly, the mounting member 500 is fixed to the inner shell wall of the casing 100, and the motor 200 and the pump mechanism 300 can be mounted to the mounting member 500. In this way, during assembly, the motor 200 and the pump mechanism 300 can be assembled to the mounting member 500 first, and then the two can be assembled into the casing 100 as a unit.

[0079] It should be noted that the motor 200 and the pump mechanism 300 will generate vibration during operation, so that the connection reliability of the pipeline connected between the outlet end 320 of the pump mechanism 300 and the first flow channel 211 of the output shaft 210 is poor and is prone to falling off. In view of the above problem, the present application is to disassemble the pump mechanism 300 into a power end 330, a liquid inlet end 310 and an outlet end 320, and integrate the outlet end 320 on the connecting piece 400 and the mounting piece 500, so as to reduce the resonance and improve the connection reliability of the connection between the second flow channel 410 of the connecting piece 400 and the outlet end 320 of the pump mechanism 300.

In this way, the mounting piece 500 is blocked between the connecting piece 400 and the power end 330 of the pump mechanism 300, so that most of the vibration of the pump body is transmitted to the mounting piece 500. The mounting piece 500 and the inner shell wall of the casing 100 can be provided with a damping member, and the mounting piece 500 can eliminate vibration through damping connection, so that the vibration transmitted from the power end 330 of the pump mechanism 300 to the connecting piece 400 is small or even none. In this way, the influence of the vibration of the power end 330 of the pump mechanism 300 on the connecting piece 400 is reduced, and the connection reliability of the connection between the second flow channel 410 of the connecting piece 400 and the outlet end 320 of the pump mechanism 300 is improved. In addition, integrating the outlet end 320 on the mounting piece 500 and the connecting piece 400 not only facilitates assembly, but also shortens the waterway and improves the connection reliability.

[0082] Specifically, the piston 332 reciprocates in the pump cavity to pump the liquid in the pump cavity out of the outlet hole; the valve of the outlet end 320 is a one-way valve to prevent liquid from flowing back into the pump cavity through the outlet hole. In this scheme, the mounting piece 500 forms the pump cavity and the outlet hole to realize the purpose of integrating the valve part of the outlet end 320.

[0085] Specifically, the liquid outlet passage of the second end cover 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 scheme, the connecting member 400 and the second end cover portion 322 of the liquid outlet end 320 are an integral piece, so that the liquid outlet passage and the second flow channel 410 are integrated, which is conducive to improving the connection reliability of the communication, improving the smoothness of the liquid flow, and improving the convenience of assembly.

[0086] Optionally, the mounting member 500 can have a liquid inlet hole penetrating the mounting member 500 and communicating with the pump cavity of the pump mechanism 300. The first valve portion 311 of the liquid inlet end 310 can be arranged at the liquid inlet hole, and the first valve portion 311 of the liquid inlet end 310 can allow the liquid to be pumped into the pump cavity through the liquid inlet hole and prevent the liquid from flowing out through the liquid inlet hole.

[0087] Specifically, the piston 332 reciprocates in the pump cavity, which can cause the liquid to be pumped into the pump cavity from the liquid inlet hole; the valve of the liquid inlet end 310 is a one-way conduction function to avoid the liquid flowing out through the liquid inlet hole. In this scheme, the mounting member 500 forms the pump cavity and the liquid inlet hole, which realizes the purpose of integrating the first valve portion 311 of the liquid inlet end 310.

[0088] Optionally, at least part of the connecting member 400 and the first end cover portion 312 of the liquid inlet end 310 can be an integral piece formed by an integral molding process, and the first end cover portion 312 of the liquid inlet end 310 can cover the liquid inlet hole, and the first end cover portion 312 of the liquid inlet end 310 can be formed with a liquid inlet flow channel communicating with the liquid inlet hole, which can communicate with the third flow channel 420 of the connecting member 400. In this way, the liquid inlet passage of the first end cover portion 312 of the liquid inlet end 310 can guide the flow direction of the liquid flowing into the liquid inlet hole. In this scheme, the connecting member 400 and the first end cover portion 312 of the liquid inlet end 310 are an integral piece, so that the liquid inlet passage and the third flow channel 420 are integrated, which is conducive to improving the connection reliability of the communication, improving the smoothness of the liquid flow, and improving the convenience of assembly.

[0089] Referring to FIGS. 8-11, optionally, the mounting member 500 can include a first mounting portion 510 having a first side and a second side oppositely arranged along the liquid outlet direction of the liquid outlet end 320. The motor 200 and the power end 330 of the pump mechanism 300 can be arranged along the axial direction of the output shaft 210 at the first side of the first mounting portion 510.

The mounting member 500 can have a through hole 530 for the connecting member 400 to pass through and limit the axial movement of the connecting member 400 along the output shaft 210. In this way, the connecting member 400 can be limited by the through hole 530 to provide upward support and limit for the connecting member 400 to avoid up and down vibration of the connecting member 400. Optionally, the control board 720 can be mounted at the side of the first mounting portion 510 away from the motor 200 by the fourth fastener 924. The fourth damping member 914 can be arranged between the control board 720 and the inner shell wall of the casing 100.

[0090] Referring to FIGS. 7 and 8, optionally, the mounting member 500 can further include a second mounting portion 520 which can be coupled to the first side of the first mounting portion 510, and the second mounting portion 520 and the first mounting portion 510 can jointly define a containing space for wrapping the outer side surface of the motor 200. In this way, the mounting member 500 wraps 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 achieving that the vibration transmitted from the motor 200 to the connecting member 400 is small or even none. 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 second flow passage 410 of the connecting member 400 and the first flow passage 211 of the motor 200 is improved. Optionally, referring to FIG. 8, the first mounting portion 510 and the second mounting portion 520 can be fastened by the second fastener 922.

In this way, the vibration transmission between the motor 200 and the mounting member 500 can be reduced by the damping member.

The output shaft 210 of the motor 200 can pass through the motor body 220, and both axial ends of the output shaft 210 can pass out of the motor body 220. The bottom surface of the motor body 220 and the inner groove wall of the mounting groove 450 can jointly form a limiting space for limiting the fourth seal 840. The limiting space can limit the fourth seal 840 at both axial ends of the output shaft 210. In this way, the fourth seal 840 can be limited by the bottom surface of the motor body 220 of the motor 200 and the groove bottom wall of the mounting groove 450 to avoid moving with vibration.

[0094] Referring to FIG. 12, the second flow channel 410 can include a first flow section 411 and a second flow section 412 communicated in sequence.

[0095] Further, the first arc section 4121 can be higher than the pump mechanism 300, and the first arc section 4121 can have an arc center towards the pump mechanism 300, so that the liquid flows more gently towards the first flow channel 211, further reducing the resistance of the flow channel inner wall to the liquid.

[0096] Optionally, the second flow section 412 further includes a second arc section 4122 circularly arcuate between the first flow channel 211. The circular arc transition is used to reduce the resistance of the flow channel inner wall to the liquid, facilitating the flow of the liquid.

[0097] Further, the second arc section 4122 has an arc center towards the motor 200, so that the second arc section 4122 and the first flow channel 211 are smoothly joined, facilitating the flow of the liquid.

[0098] Referring to FIG. 12 and FIG. 13, alternatively, the connecting member 400 can include a first connecting portion 430 and a second connecting portion 440 connected to each other.

In this way, the protruding section 443 and part of the cover plate section 442 can form the mounting groove 450 mentioned above.

[0100] Referring to FIG. 8 and FIG. 14, the power assembly (the motor 200 and the pump mechanism 300) and the charging receiving assembly 730 can be assembled in the mounting member 500, so that the mounting member 500, the power assembly, and the charging receiving assembly 730 can be assembled as a whole module in the inner cavity of the casing 100, to realize modular assembly and improve 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 casing 100 and cooperate with the charging emitting assembly 3000 outside the casing 100. Further, the control board 720 can be arranged on the other side of the mounting member 500 along the second direction Y, so that the control board 720 can face the inner wall of the other side of the casing 100 and cooperate with the keys arranged on the side.

[0101] It is worth noting that the oral cleaning device provided by the embodiments of the present application is generally placed in a relatively humid place such as a bathroom, and if an exposed charging interface is arranged on the casing 100 of the device, external water vapor will pollute the charging interface and affect the use of the device. Therefore, the oral cleaning device provided by the embodiments of the present application adopts a wireless charging mode to avoid opening a charging interface on the casing 100 of the device, to improve the charging safety and avoid water entering through the opening to damage the internal components of the casing.

[0102] Referring to FIG. 14 and FIG. 15, the charging receiving component 730 can include a charging receiving member 731 and a first magnet 732. The charging receiving member 731 can cooperate with the charging transmitting component 3000 to achieve power transmission. The first magnet 732 can be disposed on the periphery of the charging receiving member 731, and the first magnet 732 and the charging receiving member 731 can have a spacing therebetween to avoid the first magnet 732 affecting the charging receiving member 731. In addition, the first magnet 732 can be magnetically attracted to the charging transmitting component 3000.

[0103] For example, referring to FIG. 1, FIG. 14, and FIG. 16, the charging transmitting component 3000 can include a circuit board 3200, which can be provided with a plurality of electrical devices. At least one of the electrical devices can electrically connect the charging transmitting member 3300 to a power line, so that external power can be transmitted to the charging transmitting member 3300 through the power line. A second magnet 3400 can be disposed on the periphery of the charging transmitting member 3300, and the second magnet 3400 and the charging transmitting member 3300 can have a spacing therebetween to avoid affecting the charging transmitting member 3300. During charging, the charging transmitting component can be connected to the oral cleaning device 1000 by using the magnetic attraction between the first magnet 732 and the second magnet 3400.

[0104] Further, the number of first magnets 732 can be multiple, and at least two of the multiple first magnets 732 can be spaced apart along the first direction X to prevent the charging transmitting component 3000 from sliding due to gravity when the device is vertically placed on a table or the like along the first direction X for charging. Similarly, the number of second magnets 3400 can also be multiple, and at least two of the multiple second magnets 3400 can be spaced apart along the first direction X.

[0105] When the charging transmitting member 3300 and the charging receiving member 731 can have the following two possible arrangements:

[0106] In one of the possible arrangements of the charging transmitting member 3300 and the charging receiving member 731, the charging transmitting member 3300 can be a first coil, and the first coil can generate a magnetic field according to the power provided by the power line. The charging receiving member 731 can be a second coil, and the second coil can be spaced apart from the first coil along the axis direction of the first coil, and the second coil can induct the magnetic field generated by the first coil and generate power. In this way, the coupling between the charging transmitting member 3300 and the charging receiving member 731 can be achieved by using the principle of electromagnetic induction to generate energy interaction.

[0107] Specifically, the first coil can be connected in series in a closed loop of the power line, and can generate a changing magnetic field when the closed loop is conducted. In order to improve the strength of the changing magnetic field generated by the first coil after being powered, the first coil can be formed by winding a straight wire along a straight line direction, and the number of turns of the first coil is the number of turns of the wire. The first coil has multiple turns, and each turn generates a magnetic field after being powered, and these magnetic fields can be superimposed to enhance the field strength of the first coil.

[0108] In addition, the second coil can be connected in series in the closed loop of the energy source 710. When the magnetic flux passing through the second coil changes, the second coil generates an induced current to power the energy source 710. In order to cause the magnetic flux to change and generate an induced current, specifically, an alternating current is passed through the first coil, so that the first coil generates an alternating magnetic field, and at least part of the alternating magnetic field passes through the second coil. During the change of the current in the first coil over time, the magnetic flux passing through the second coil also changes, so that the second coil generates an induced current.

[0109] In another possible arrangement of the charging transmitting member 3300 and the charging receiving member 731, the charging transmitting member 3300 can be a third coil, and the third coil is a self-oscillation system. An oscillator can be connected in series between the power source and the third coil. The oscillator can output a high-frequency oscillation current to the third coil, and the third coil receives the high-frequency oscillation current and emits electromagnetic waves outward, and forms a non-radiating magnetic field around the third coil. In this way, the third coil can convert the electrical energy of the power source into a magnetic field.

[0110] In addition, the charging receiving member 731 can be a fourth coil, and the fourth coil can have a natural frequency. When the natural frequency of the fourth coil is the same as the frequency of the electromagnetic waves emitted by the third coil, the fourth coil generates a stronger oscillation current. In this way, the fourth coil can convert the magnetic field into electrical energy.

[0111] Referring to FIGS. 14 and 15, optionally, the mounting member has a positioning slot for accommodating the charging receiving assembly, and the positioning slot has an opening facing away from the accommodation space. In this way, the positioning slot is used to limit the position of the charging receiving assembly, and quick positioning and assembly between the charging receiving assembly and the mounting member can be achieved.
