[0016] The following describes the technical aspects of the embodiments of this application clearly and completely, with reference to the drawings of the embodiments. It is clear that the embodiments described are only some, not all, embodiments of this application. Any other embodiments obtained by those skilled in the art without creative work based on the embodiments of this application shall all fall within the scope of protection of this application.

[0017] Referring to Figures 1, 2, and 3, the oral hygiene device 10 according to the first embodiment of the present application may specifically include, for example, a brush head 100, a handle 200, and an airflow generator 300.

[0018] A base 110 may be provided at one end of the brush head 100, and brush bristles 111 and airflow holes 112 may be provided on one side of the base 110, and the airflow holes 112 and brush bristles 111 may be provided on the same side of the base 110. The airflow holes 112 may include, for example, multiple holes or there may be, for example, one hole, but this embodiment is not limited thereto. A first airflow passage 101 is provided inside the brush head 100, and the first airflow passage 101 is in communication with the airflow holes 112, and the first airflow passage 101 may be formed, for example, by making the inside of the brush head 100 hollow, or by providing an airflow tube inside the brush head 100, but this is merely an illustrative description. The handle 200 may include, for example, a case 210, and the handle 200 is connected to the brush head 100, and the handle 200 may be detachably connected to the brush head 100, or detachably connected to the brush head 100. A second airflow passage 201 is provided inside the case 210, and the second airflow passage 201 is connected to the first airflow passage 101. When the brush head 100 is detachably connected to the handle 200, both the first airflow passage 101 and the second airflow passage 201 may be detachably connected, for example, and the first airflow passage 101 and the second airflow passage 201 may be a single airflow passage that is integrally molded and communicates with each other, for example, and when the brush head 100 is detachably connected to the handle 200, both the first airflow passage 101 and the second airflow passage 201 may be detachably connected, for example.

[0019] The airflow generator 300 is housed inside the case 210 and has an airflow output port 310, which is connected to the second airflow passage 201. The airflow generator 300 may be, for example, an air pump, and more specifically, a diaphragm pump or an electromagnetic pump. The airflow generator 300 may further include, for example, an air inlet, and the case 210 is provided with an air intake, which may be, for example, one or multiple intakes, and the air intake may be provided, for example, in the case 210 near the airflow generator 300, or, for example, in other locations in the case 210 as needed. With this configuration, air enters the airflow generator 300 through the air intake and air inlet, and an airflow can be generated in the airflow generator 300. Alternatively, an intake pipe 202 may be provided inside the case 210, with one end of the intake pipe 202 connected to the air inlet of the airflow generator 300 and the other end exposed to the air, so that air enters the airflow generator 300 through the intake pipe 202. The intake pipe 202 may also be further provided with, for example, a one-way valve, so that the gas enters in one direction and the airflow generation effect is enhanced. The airflow generator 300 is capable of generating airflow, which is ejected from the airflow hole 112 via the second airflow passage 201 and the first airflow passage 101. In this way, the oral cleaning device 10 ejects airflow through the airflow hole 112, generating dense microbubbles with the ejected airflow, toothpaste, and water. The impact generated by the instantaneous collapse and bursting of the microbubbles cleans the gaps between teeth, enhancing the teeth cleaning effect and further improving the user experience.

[0020] The oral cleaning device 10 may further include a vibrating member that, for example, oscillates or rotates the brush bristles 111 of the brush head 100, and the vibrating member may be, for example, a motor 400, which is used as an example here, but the present invention is not limited thereto. The motor 400 is provided in the case 210, and specifically, for example, it may be provided on the side of the airflow generator 300 closer to the brush head 100, and the motor 400 is connected to the brush head 100, and the motor 400 can clean teeth by generating frictional force by oscillating or rotating the brush bristles 111 via the brush head 100. The case 210 may further include, for example, a bracket 500, a circuit board 600, and a battery 700. The bracket 500 is located inside the case 210, and the airflow generator 300, motor 400, circuit board 600, and battery 700 are located on the bracket 500. The battery 700 is connected to the airflow generator 300, motor 400, and circuit board 600 and supplies power to the motor 400, airflow generator 300, and circuit board 600. The oral hygiene device 10 may further include, for example, a switch, which is connected to the circuit board 600. The circuit board 600 controls the operation of the motor 400 and airflow generator 300 by turning the corresponding switch on or off. The airflow generator 300 is located between the motor 400 and the battery 700, and the motor 400 is located at the end closest to the brush head 100. The circuit board 600 may be located between, for example, the motor 400 and the case 210. This configuration allows for more efficient use of space within the case 210, miniaturization of the handle 200, easier gripping by the user while ensuring cleaning functionality, and further improvement of the user experience. Of course, in other embodiments, the battery 700 may be placed between the airflow generator 300 and the motor 400, or the battery 700 and the airflow generator 300 may be placed side by side, but any of these arrangements is within the scope of protection of this application.

[0021] Specifically, the case 210 may include, for example, a drive shaft 410, which can oscillate or rotate the brush bristles 111 of the brush head 100. The drive shaft 410 may be provided, for example, within a motor 400, or at the center of the motor 400, and the drive shaft 410 may have opposing first ends 411 and second ends 412, and the drive shaft 410 may be provided with, for example, a second airflow passage 201 extending from the first end 411 to the second end 412, with the first end 411 of the drive shaft 410 connected to the brush head 100 and the second end 412 connected to the airflow output port 310 of the airflow generator 300. The motor 400 oscillates or rotates the brush bristles 111 via the drive shaft 410. The drive shaft 410 may be provided as a hollow structure, for example, such that a second airflow passage 201 is formed in the drive shaft 410. The airflow generated by the airflow generator 300 passes through the airflow output port 310, and is ejected from the airflow hole 112 via the second airflow passage 201 in the drive shaft 410 and the first airflow passage 101 in the brush head 100. In this way, airflow ejection by the oral cleaning device 10 is realized, the structure is simple, the components inside the case 210 are compactly arranged, the handle 200 is miniaturized, the cleaning function is guaranteed, and it is easier for the user to grip, further improving the user experience.

[0022] Referring to Figure 4, a connecting pipe 413 may be further provided around the airflow output port 310 and the second end 412 of the drive shaft 410, and the connecting pipe 413 is tightly provided around the airflow output port 310 and the second end 412 of the drive shaft 410. The connecting pipe 413 may be, for example, a soft gel pipe, and in order to connect the airflow output port 310 and the second airflow passage 201 to each other, for example, one end of the connecting pipe 413 may be provided around the airflow output port 310 and the other end may be provided around the second end 412 of the drive shaft 410, thereby improving the airtightness of the connection between the airflow output port 310 and the second airflow passage 201, and preventing the connection between the airflow output port 310 and the drive shaft 410 from coming loose due to vibration of the drive shaft 410 when the motor 400 is operating, and further enhancing the airflow transmission effect.

[0023] Furthermore, the first end 411 of the drive shaft 410 is airtightly connected to the first airflow passage 101. Airtight connection means that the first end 411 of the drive shaft 410 and the first airflow passage 101 are connected to each other and are airtight. In this way, the airtightness of the airflow passage is improved, and the airflow can be output in one direction.

[0024] Specifically, a sealing member 190 may be provided at the first end 411 of the drive shaft 410, with one end of the sealing member 190 tightly fitted around the first end 411 and the other end extending from the drive shaft 410 and housed within the first airflow passage 101. The sealing member 190 may be, for example, a silica gel hose, which may be tightly fitted around the first end 411 of the drive shaft 410 and the other end tightly bonded to the first airflow passage 101. This improves the airtightness of the airflow passage and ensures that the airflow is output in one direction. The first airflow passage 101 gradually narrows along the direction from the motor 400 toward the base 110, further enhancing the airflow ejection effect and improving the cleaning effect of the oral hygiene device 10. A one-way valve may be provided at the end of the first airflow passage 101 closest to the airflow hole 112. In this way, the airflow can be ejected in one direction, enhancing the airflow ejection effect and further improving the cleaning effect of the oral hygiene device 10.

[0025] A drive shaft snap-fit ​​member 150 may be further provided around the first end 411 of the drive shaft 410, and the drive shaft snap-fit ​​member 150 is provided on the side of the seal member 190 closer to the motor 400, and the drive shaft snap-fit ​​member 150 is fixedly connected to the seal member 190. The drive shaft snap-fit ​​member 150 may be injection-molded onto the drive shaft 410, and then the seal member 190 may be injection-molded onto the drive shaft 410, and the drive shaft snap-fit ​​member 150 and the seal member 190 may be fixedly connected. Of course, the drive shaft snap-fit ​​member 150 may be connected to the seal member 190 by other means, such as adhesive. Referring to Figure 5, a first snap-fit ​​portion 152 may be provided on the outer side of the drive shaft snap-fit ​​member 150, farther from the drive shaft 410, and a second snap-fit ​​portion 143 may be provided on the end of the brush head 100, farther from the base 110. The first snap-fit ​​portion 152 and the second snap-fit ​​portion 143 are detachably connected to detachably connect the handle 200 and the brush head 100.

[0026] In one specific embodiment of this model, the second airflow passage 201 may be provided, for example, between the motor 400 and the case 210. Specifically, for example, the second airflow passage 201 may be provided as a vent pipe, which is provided between the motor 400 and the case 210, i.e., the vent pipe and the motor 400 are provided in parallel, with one end of the vent pipe connected to the airflow output port 310 of the airflow generator 300 and the other end connected to the first airflow passage 101 of the brush head 100. In this way, the airflow generated by the airflow generator 300 passes through the second airflow passage 201 and the first airflow passage 101 and is ejected from the airflow hole 112.

[0027] As shown in Figures 6 to 8, another brush head 100 of the oral hygiene device 10 according to the present invention differs from the aforementioned brush head 100 in the following respects. A through-passage fluid passage 113 is provided in the base 110. One end of the fluid passage 113 is located on the side of the base 110 where the airflow hole 112 is provided. The gas flowing through the first airflow passage 101 is ejected toward the airflow hole 112, forming a negative pressure area around the airflow hole 112. Because the liquid pressure near the other end of the brush head 100, which is closer to the fluid passage 113, is greater than the pressure in the negative pressure area, the liquid near the brush head 100 can be circulated and supplied around the airflow hole 112 via the fluid passage 113. Furthermore, the gas ejected from the airflow hole 112 combines with the liquid on the tooth-facing side of the brush head 100, generating abundant bubbles. These bubbles are blown onto the tooth surface and gaps, and the impact generated by the instantaneous collapse and bursting of the bubbles cleans the tooth surface and gaps, enhancing the tooth cleaning effect.

[0028] In this embodiment, the base 110 includes a first side 114 and a second side 115, the first side 114 and the second side 115 being adjacent to or facing each other, and the base 110 is provided with a first fluid port 116 and a second fluid port 117 communicating with both ends of the fluid passage 113, the first fluid port 116, the airflow holes 112 and the brush bristles 111 are all provided on the first side 114, and the second fluid port 117 is provided on the second side 115. Since the first side 114 and the second side 115 are provided adjacent to or opposite each other, when gas is ejected from the airflow hole 112, some of the liquid near the brush head 100 passes through the second liquid inlet 117, the liquid passage 113, and the first liquid inlet 116 in sequence, and can continuously replenish the liquid around the airflow hole 112. As a result, the liquid combines with the gas to form abundant bubbles, and after the bubbles burst, the formed liquid passes through the second liquid inlet 117, the liquid passage 113, and the first liquid inlet 116 again, circulating and flowing around the airflow hole 112.

[0029] Specifically, a negative pressure area can be formed around the airflow hole 112, and the first liquid inlet 116 is in communication with the negative pressure area. The gas flowing through the first airflow passage 101 is ejected from the airflow hole 112, and then the gas is pressed by the liquid to form spherical bubbles. As a result, gas is continuously ejected from the airflow hole 112, and the liquid located near the second liquid inlet 117 is supplied into the liquid inlet 113 and flows from the first liquid inlet 116 into the negative pressure area around the airflow hole 112. Therefore, a large amount of bubbles are continuously generated on the side of the brush head 100 facing the toothbrush, and the impact generated by the instantaneous collapse and bursting of the bubbles can clean the gaps between teeth.

[0030] In this embodiment, the first liquid inlet 116 and the second liquid inlet 117 are located on opposite sides of the base 110, respectively. A large amount of bubbles are generated on the side of the brush head 100 facing the teeth, causing the liquid space to be compressed and occupied by the bubbles. On the other hand, the gas ejected from the airflow hole 112 needs to combine with the liquid to generate new bubbles. If the second liquid inlet 117 is located on the side of the base 110 farther from the first liquid inlet 116, the liquid near the second liquid inlet 117 can be continuously replenished on the side of the base 110 facing the teeth by passing through the second liquid inlet 117, the liquid passage 113, and the first liquid inlet 116. In other embodiments, the second fluid port 117 may be provided on the base 110 adjacent to the first fluid port 116, and the second fluid port 117 can be used to supply liquid near the base 110 to the side of the brush head 100 facing the teeth via the fluid passage 113 and the first fluid port 116.

[0031] In this embodiment, the first side 114 is provided with an opening area 1142 and a mounting area 1144. The mounting area 1144 surrounds the opening area 1142, and the airflow holes 112 and the first liquid conduit 116 are located in the opening area 1142. There are multiple brush bristles 111, and these multiple brush bristles 111 are provided in the mounting area 1144. The brush bristles 111 located in the mounting area 1144 are spaced apart from the airflow holes 112 and the first liquid conduit 116 located in the opening area 1142. This prevents the airflow holes 112 and the first liquid conduit 116 from being obstructed or interfered with by the brush bristles 111, ensuring that the liquid can pass sequentially through the second liquid conduit 117, the liquid conduit passage 113, and the first liquid conduit passage 113 and be output to the side facing the teeth on the base 110. As a result, the gas ejected from the airflow holes 112 combines with the liquid to continuously generate abundant bubbles.

[0032] In this embodiment, the inner surface 1132 of the fluid passage 113 is connected to the outer surface 1102 of the base 110 through the flow guide surface 1134, and the flow guide surface 1134 is a smooth curved surface. In this way, the liquid can flow smoothly sequentially along the outer surface 1102 of the base 110, the flow guide surface 1134, and the fluid passage 113, and the smooth curved surface reduces the resistance generated during liquid flow.

[0033] As shown in Figure 9, the further brush head 100 of the oral hygiene device 10 according to the present invention differs from the aforementioned brush head 100 in the following respects. The airflow port 112 is annular in shape and surrounds the first liquid inlet 116. After the gas in the first airflow passage 101 is blown out from the airflow port 112, a negative pressure area is formed both inside and outside the annular airflow port 112. The liquid located in the negative pressure area inside the annular airflow port 112 is continuously used and consumed to combine with the gas and generate bubbles. Meanwhile, since the first liquid inlet 116 is surrounded by the airflow port 112 and the second liquid inlet 117 is located on the second side, the second liquid inlet 117 can guide the liquid into the liquid inlet passage 113. The liquid located in the passage can be supplied to the negative pressure area inside the annular airflow port 112 via the first liquid inlet 116. As a result, the liquid is continuously replenished in the negative pressure area, ensuring that the gas ejected from the airflow port 112 is continuously pressed by the liquid to form spherical bubbles.

[0034] In another embodiment of the present application, there are multiple airflow holes 112, which are arranged around the first liquid inlet 116, where the multiple airflow holes 112 may be arranged in a regular pattern, or the multiple air inlets 24 may be arranged in an irregular pattern.

[0035] As shown in Figures 10 and 11, yet another brush head 100 of the oral hygiene device 10 according to the present invention differs from the brush head 100 described above in the following respects: It further includes a first extended portion 130 and a second extended portion 140, both of which are connected to the same side of the base 110; the airflow hole 112 is provided in the first extended portion 130; the first liquid guide port 116 is provided in the second extended portion 140; part of the first airflow passage 101 is provided inside the base 110; the other part of the first airflow passage 101 is provided inside the first extended portion 130; part of the liquid guide passage 113 is provided inside the base 110; the other part of the liquid guide passage 113 is provided inside the second extended portion 140. The structure is provided with a first extended portion 130 and a second extended portion 140. By providing these, the distance between the airflow holes 112 and the first liquid guide port 116 and the gaps between the teeth is shortened, and the distance between the airflow holes 112 and the first liquid guide port 116 and the surface of the teeth is also shortened. As a result, the bubbles formed after the gas ejected from the airflow holes 112 combines with the liquid can quickly adhere to the surface and gaps of the teeth, ensuring that more bubbles can effectively clean the surface and gaps of the teeth through the impact generated by instantaneous collapse and bursting.

[0036] In this embodiment, the height at which the first extended portion 130 protrudes from the surface of the base 110 is H1, the height at which the second extended portion 140 protrudes from the surface of the base 110 is H2, and the height at which the brush bristles 111 protrude from the surface of the base 110 is H3, of which 0 cm

[0037] ​In this embodiment, the first extending portion 130 has a flexible material structure, and when the first extending portion 130 comes into contact with the tooth surface, the first extending portion 130 is deformable, thus preventing the first extending portion 130 from hard impacting the tooth and causing discomfort in the oral cavity.

[0038] In this embodiment, the second extended portion 140 has a flexible material structure, and when the second extended portion 140 comes into contact with the tooth surface, the second extended portion 140 is deformable, thus preventing the second extended portion 140 from hard impacting the tooth and causing discomfort in the oral cavity.

[0039] In this embodiment, both the first extended portion 130 and the second extended portion 140 are made of a flexible material so that they can gently clean the surface of the tooth.

[0040] In another embodiment of the present invention, the brush head 100 further includes a casing connected to a first side 114, the casing surrounding the airflow holes 112 and the first liquid conduit 116, and a negative pressure area may be formed around the airflow holes 112 so as to be located within the area enclosed by the casing. Specifically, the casing is annular in shape, and by enclosing the airflow holes 112 and the first liquid conduit 116, the casing prevents excessive dispersion of the negative pressure area formed around the airflow holes 24 when gas is ejected from the airflow holes 112, the casing can avoid being affected by the liquid pressure located outside the casing, and the casing can guide the gas ejected from the air conduit 23, thereby enhancing the ability to supply liquid near the brush head 100 into the negative pressure area formed around the gas from the first liquid conduit 24 via the liquid conduit passage 1132.

[0041] Referring to Figures 12A to 15, the second embodiment of the present application provides an oral hygiene device 10 which differs from the oral hygiene device 10 of the previously described embodiment in the following respects. In this embodiment, the brush head 100 includes a brush head body 140 and a sealing member 190.

[0042] Referring to Figure 16, a position regulating portion 141 is provided on the inner wall of the brush head body 140. The drive shaft 410 is inserted and connected into the brush head body 140, and the position regulating portion 141 is located in the insertion path of the drive shaft 410. When the drive shaft 410 is inserted into the brush head body 140, the drive shaft 410 is inserted into a predetermined position via the position regulating portion 141, thereby connecting the first airflow passage 101 and the second airflow passage 201. The sealing member 190 may be an elastically deformable structural member such as a rubber member or a silica gel member, and the sealing member 190 is sealed and connected between the drive shaft 410 and the brush head body 140 in order to seal and connect the first airflow passage 101 and the second airflow passage 201. By providing a sealing member 190 between the drive shaft 410 and the brush head body 140, the first airflow passage 101 and the second airflow passage 201 are sealed together, improving the sealing performance of the connection between the first airflow passage 101 and the second airflow passage 201, ensuring the airflow or liquid ejection effect, and thereby enhancing the cleaning effect of the oral hygiene device 10. Furthermore, by providing a position regulating part 141 inside the brush head body 140, when the drive shaft 410 is inserted into the brush head body 140, the drive shaft 410 can be inserted into a predetermined position inside the brush head body 140 via the position regulating part 141, further ensuring the sealing performance between the first airflow passage 101 and the second airflow passage 201.

[0043] Referring to Figure 15, the airflow generator 300 is provided with an airflow input port 320 and an airflow output port 310. The bracket 500 includes a first mounting frame 510 and a second mounting frame 520, which together form an electronic component housing chamber 530. The airflow generator 300, motor 400, circuit board 600, and battery 700 are all housed in the electronic component housing chamber 530. The battery 700 is electrically connected to the airflow generator 300, motor 400, and circuit board 600 to supply power to them. The oral hygiene device 10 may also be further provided with, for example, a switch, which is connected to the circuit board 600. Of course, this embodiment is not limited thereto.

[0044] Furthermore, the brush head 100 further includes a drive shaft snap-fit ​​member 150, which is connected inside the brush head body 140 and is circumferentially mounted on the drive shaft 410 and connected to the drive shaft 410, thereby enabling a detachable connection between the brush head 100 and the handle 200. Specifically, the drive shaft 410 may have, for example, a first end near the position regulating portion 141, the drive shaft snap-fit ​​member 150 is circumferentially mounted on the first end of the drive shaft 410, and the first end of the drive shaft 410 has a projection 412 protruding from the drive shaft snap-fit ​​member 150, the drive shaft snap-fit ​​member 150 is connected inside the brush head body 140, and the sealing member 190 is circumferentially mounted on the drive shaft snap-fit ​​member 150 and the projection 412 of the drive shaft 410 and is sealedly connected to the brush head body 140.

[0045] Referring to Figures 17A and 17B, the seal member 190 is provided with a drive shaft connection portion 192 and a snap-fit ​​connection portion 194. The structure of the drive shaft connection portion 192 may be, for example, adapted to the protrusion 412 of the drive shaft 410, and the snap-fit ​​connection portion 194 may be, for example, adapted to the connection point of the drive shaft snap-fit ​​member 150. The drive shaft connection portion 192 is sealed around the protrusion 412, and the snap-fit ​​connection portion 194 is sealed around the drive shaft snap-fit ​​member 150, thereby sealing the seal member 190 to the drive shaft 410 and the drive shaft snap-fit ​​member 150. The seal member 190 is provided inside the brush head body 140, and the outer wall of the seal member 190 may be attached to the inner wall of the brush head body 140, for example, thereby sealing the seal member 190 to the brush head body 140. Specifically, a seal ring 160 may be further provided on the outer wall of the seal member 190 closest to the brush head body 140, and the seal ring 160 is sealed to the inner wall of the brush head body 140, thereby sealing the seal member 190 and the brush head body 140. When the drive shaft 410 is inserted into a predetermined position inside the brush head body 140 via the position regulating part 141, the seal member 190 can be tightly connected between the brush head body 140 and the drive shaft 410, thereby achieving sealed communication between the first airflow passage 101 and the second airflow passage 201.

[0046] In one specific embodiment of this model, referring to Figure 18A, the position restricting portion 141 may include, for example, a plurality of positions restricting portions 141, which are spaced apart on the inner wall of the brush head body 140. Providing a plurality of positions restricting portions 141 allows for more favorable position restriction of the drive shaft 410 during installation. The positions restricting portion 141 may be, for example, a projection extending from the inner wall, and the positions restricting portion 141 and the brush head body 140 may be, for example, an integrated structure, but of course, this model is not limited thereto. Between any two adjacent positions restricting portions 141, a cutout portion 142 may be further provided. In this way, the strength of the side wall of the brush head body 140 is increased, and shrinkage of the side wall of the brush head body 140 is reduced, while weight is reduced, material is saved, and costs are lowered.

[0047] Referring to Figures 18B and 19, a first snap-fit ​​portion 152 is provided on the side of the drive shaft snap-fit ​​member 150 that is away from the drive shaft 410. That is, the first snap-fit ​​portion 152 is provided on the outside of the drive shaft snap-fit ​​member 150, and a second snap-fit ​​portion 143 is provided on the inner wall of the brush head body 140 corresponding to the first snap-fit ​​portion 152. The drive shaft snap-fit ​​member 150 is detachably connected to the brush head body 140 via the first snap-fit ​​portion 152 and the second snap-fit ​​portion 143. The first snap-fit ​​portion 152 may be, for example, an elastic projection, and the second snap-fit ​​portion 143 may be, for example, a groove. When the drive shaft snap-fit ​​member 150 enters the brush head body 140, the elastic projection can be snap-fitted into the groove by deforming, for example, by being pressed by an external force, entering the groove, and then recovering its deformation. Of course, the first snap-fit ​​portion 152 may be, for example, a groove, and the second snap-fit ​​portion 143 may be a projection, but this embodiment is not limited to these.

[0048] Referring again to Figures 18B and 19, in one specific embodiment of this embodiment, the drive shaft snap-fit ​​member 150 is provided with a drive shaft snap-fit ​​portion 154 for connecting to the drive shaft 410. A communication port 144 is further provided at the end of the brush head body 140 that is separated from the base 110, and the drive shaft snap-fit ​​member 150 enters into the brush head body 140 through the communication port 144 and connects to the brush head body 140. Two guide protrusions 145 are provided on the inner wall of the brush head body 140 close to the communication port 144, and a guide portion 146 is formed between the two guide protrusions 145, and the drive shaft snap-fit ​​portion 154 is located between the two guide protrusions 145, and the guide portion 146 is provided corresponding to the drive shaft snap-fit ​​portion 154. The two guide protrusions 145 can guide the drive shaft snap-fit ​​member 150 into the interior of the brush head body 140 at the correct angle, thereby preventing the engagement connection between the brush head body 140 and the drive shaft snap-fit ​​member 150 from failing due to incorrect orientation, and ensuring that the drive shaft 410 can be reliably and detachably connected to the drive shaft snap-fit ​​portion 154 after being inserted into the interior of the brush head body 140. This improves the convenience and accuracy of the connection operation, reduces the difficulty of operation for the user, and further enhances the user experience.

[0049] In one embodiment of this model, the base 110 may include, for example, a base body 118 and a flow guide member 119, and the fluid passage 113 and the flow guide surface 1134 are provided on the flow guide member 119, and the base body 118 may be provided with, for example, a mounting hole 1182, and the flow guide member 119 is connected to the base body 118 via the mounting hole 1182. In some embodiments, the flow guide member 119 and the base body 118 may be, for example, an integrally molded structure, or the integrally molded structure may be formed by, for example, secondary injection molding. A soft gel layer 170 is provided on the outside of the base 110 that is separated from the first airflow passage 101, and the soft gel layer 170 may be, for example, a soft gel material such as silica gel or rubber, and by providing the soft gel layer 170 on the outside of the base 110, the part of the base 110 that comes into contact with the mouth when used by the user becomes the soft gel layer 170, improving comfort during use and further enhancing the user experience.

[0050] Referring to Figures 12B and 21, in one specific embodiment of this model, a retaining ring 180 may be further provided on the outside of the end of the brush head body 140 that is separated from the base 110, and a liquid storage section 182 is provided on the side of the retaining ring 180 that is closer to the base 110. The retaining ring 180 may be made of a soft gel material, for example, and may have an annular structure, for example, with the inner ring of the annular structure circumferentially attached to the brush head body 140, and since the diameter of the brush head body 140 can gradually increase from top to bottom, for example, the retaining ring 180 is tightly connected to the brush head body 140, and the retaining ring 180 is provided at an angle at the connection part and on the outside of the brush head body 140, as a result of which the liquid storage section 182 is formed. Of course, this model is not limited thereto. By providing the retaining ring 180, when a user brushes their teeth using the oral hygiene device 10, the liquid flows downward along the brush head. The liquid is stopped by the retaining ring 180 and stored in the liquid storage section 182. After use, the liquid in the liquid storage section 182 can be poured out, preventing the liquid from flowing onto the handle 200 and contaminating the user's hands, and also preventing the liquid from entering the handle 200 and damaging electronic components, thereby improving safety.

[0051] Referring to Figures 22 and 23, the oral hygiene device 10 may further include, for example, a waterproof air intake cover assembly 800, which is sealed to the handle 200 and is provided with a first air intake port 810. Gas entering through the first air intake port 810 enters the airflow generator 300 via the airflow input port 320 to generate airflow, which is then ejected from the airflow hole 112 via the airflow output port 310 through the second airflow passage 201 in the drive shaft 410 and the first airflow passage 101 in the brush head body 140. By providing the waterproof air intake cover assembly 800, water can be prevented from entering the electronic component housing chamber 530 via the first air intake port 810, thereby preventing damage to the electronic components inside the oral hygiene device 10 by water and improving the safety of the oral hygiene device 10. By providing the waterproof air intake cover assembly 800, it is possible to prevent mold growth caused by moisture entering the electronic component housing chamber 530. As a result, a healthy and pollution-free airflow is output from the airflow generator 300, avoiding any impact on the user's hygiene and health.

[0052] The waterproof intake cover assembly 800 may include, for example, an intake cover 820, a capping member 830, and a first waterproof intake member 840. The intake cover 820 is sealed to the handle 200, and a first intake port 810 is provided in the intake cover 820, which may be, for example, a plurality of intake through-holes. The capping member 830 caps the electronic component housing chamber 530, and the capping member 830 is further provided with a second intake port 832, and on the side of the capping member 830 away from the intake cover 820, an intake port 834 is further provided which communicates with the airflow input port 320, and the intake port 834 communicates with the second intake port 832. The first waterproof air intake member 840 is provided on the side of the capping member 830 closest to the air intake cover 820. The first waterproof air intake member 840 is, for example, a waterproof permeable membrane. The waterproof permeable membrane prevents mold growth due to moisture entering the electronic component housing chamber 530. As a result, a healthy and unpolluted airflow is output from the airflow generator 300, avoiding any impact on the user's hygiene and health.

[0053] Furthermore, a plurality of ribs 835 are provided on the side of the capping member 830 closest to the intake cover 820. The plurality of ribs 835 are spaced apart, and a gas passage is formed between two adjacent ribs 835. The first waterproof intake member 840 is provided on the side of the plurality of ribs 835 closest to the intake cover 820. When the first waterproof intake member 840 is covered on the capping member 830, the provision of the ribs 835 prevents the second intake port 832 from being covered by the first waterproof intake member 840 and thus preventing the intake effect from being affected.

[0054] The capping member 830 is further provided with, for example, a fourth air intake port 836, which communicates with the electronic component housing chamber 530. The waterproof air intake cover assembly 800 further includes a second waterproof air intake member 850, which is provided on the side of the capping member 830 away from the air intake cover 820 and covers the fourth air intake port 836, and the second waterproof air intake member 850 is, for example, a waterproof permeable membrane. By providing the fourth air intake port 836, it is possible to allow the flow of gas between the electronic component housing chamber 530 and the outside, thereby preventing damage to electronic components due to an imbalance in the internal air pressure of the electronic component housing chamber 530. Furthermore, by providing the second waterproof air intake member 850, it is possible to prevent liquid from entering the electronic component housing chamber 530, thereby preventing damage to the electronic components inside the oral hygiene device 10 by water. The waterproof air intake cover assembly 800 may further include, for example, a sealing connecting ring 860 connected between the air intake cover 820 and the capping member 830, thereby further improving the sealing performance of the connection.

[0055] Referring to Figures 24 to 28, a third embodiment of the present application provides an oral hygiene device 10 which differs from the oral hygiene device 10 of the previously described embodiment in the following respects. In this embodiment, the oral hygiene device 10 further includes a protective structure 330, which is connected to the intake pipe 202. The protective action of the protective structure 330 prevents bending of the intake pipe 202, further ensuring a stable output of airflow from the oral hygiene device 10, improving the practicality and stability of use of the oral hygiene device 10, and guaranteeing the functional effectiveness of the oral hygiene device 10.

[0056] In an exemplary embodiment, the intake pipe 202 includes an extended portion 204 and a curved portion 206 connected to the extended portion 204. The protective structure 330 includes a support member 332, which is connected to the extended portion 204 and / or the curved portion 206.

[0057] For example, the support member 332 is provided on the bracket 500 and connected to the intake pipe 202 along the extending direction of the intake pipe 202, and / or provided inside the intake pipe 202, that is, the support member 332 is provided inside the extending portion 204 and / or the curved portion 206, and connected to the intake pipe 202 along the extending direction of the intake pipe 202. In this application, the support member 332 is placed inside the curved portion 206 of the intake pipe 202, and the support member 332 has two characteristics: firstly, it has a support performance that prevents bending or crushing of the intake pipe 202, and secondly, it has good air permeability. By providing the support member 332, it is ensured that the airflow supplied from the intake pipe 202 is smooth, and the support member 332 plays a role in preventing clogging of the intake pipe 202. The support member 332 includes, but is not limited to, members made of soft materials that provide a support effect, such as elastic members like springs, torsion springs, and elastic sheets; silica gel sheets; silica gel pads; curved silica gel strips; spiral silica gel strips; rubber sheets; rubber pads; curved rubber strips; and spiral rubber strips.

[0058] Exemplary, the bracket 500 is provided with an opening 540, the extension portion 204 is provided along the axial direction of the bracket 500, the curved portion 206 of the intake pipe 202 is curved and penetrates the opening 540, one end of the extension portion 204 is in communication with the outside, the other end of the extension portion 204 is connected to one end of the curved portion 206, the other end of the curved portion 206 is in communication with the airflow inlet 320, and / or the opening 540 is provided adjacent to one end face of the bracket 500, and the distance between the opening 540 and one end of the extension portion 204 is greater than the distance between the end face of the bracket 500 adjacent to the opening 540 and one end of the extension portion 204.

[0059] In this application, the extended portion 204 is parallel to the axial direction of the bracket 500. The curved portion 206 curves and extends into the opening 540 via the inlet of the opening 540, the other end of the curved portion 206 penetrates the opening 540 and extends out of the outlet of the opening 540, and the other end of the curved portion 206 is connected to the airflow generator 300. By providing the opening 540 of the bracket 500, sufficient space is secured at the end face of the bracket 500, which helps in the supply of airflow through the intake pipe 202, ensures the convenience of connecting the intake pipe 202 and the airflow generator 300, considers the spatial layout of the entire device, and reduces the occurrence of situations in which airflow cannot be supplied due to collapse of the intake pipe 202. In a preferred embodiment, within the opening 540, the curved portion 206 does not contact the bracket 500, and the curved portion 206 has no other contacts other than the through connection with the bracket 500.

[0060] In another embodiment, the extended portion 204 extends along the axial direction of the bracket 500, and the other end of the curved portion 206 is connected to the circumferential surface of the bracket 500 through the opening 540. In yet another embodiment, the extended portion 204 extends circumferentially around the circumferential surface of the bracket 500, and the other end of the curved portion 206 is connected to the circumferential surface of the bracket 500 or one end face of the bracket 500 through the opening 540.

[0061] In an exemplary embodiment, the bracket 500 and the case 210 are snap-connected via a second snap-fit ​​550. In one embodiment, the bottom of the second snap-fit ​​550 is connected to the bracket 500, and the snap portion of the second snap-fit ​​550 is snap-connected to the case 210. In another embodiment, the bottom of the second snap-fit ​​550 is connected to the case 210, and the snap portion of the second snap-fit ​​550 is snap-connected to the bracket 500. In this embodiment, the snap connection of the second snap-fit ​​550 improves the strength of the connection between the bracket 500 and the case 210.

[0062] In an exemplary embodiment, the oral hygiene device 10 further includes a positioning block 560, wherein one of the bracket 500 and the case 210 is provided with a sliding groove that engages with the positioning block 560, and the positioning block 560 is provided on the other of the bracket 500 and the case 210. In one embodiment, the bracket 500 is provided with a sliding groove and the positioning block 560 is provided on the case 210. In another embodiment, the case 210 is provided with a sliding groove and the positioning block 560 is provided on the bracket 500. In this embodiment, the pre-positioning engagement between the positioning block 560 and the sliding groove improves the convenience of connection between the bracket 500 and the case 210 and facilitates the connection operation between the bracket 500 and the case 210.

[0063] In an exemplary embodiment, the protective structure 330 includes a first snap fit 334 provided on the case 210, and the intake pipe 202 is detachably connected to the first snap fit 334, thus fixing the intake pipe 202 and the case 210 relative to each other. The first snap fit 334 snaps into place on the extended portion 204 of the intake pipe 202, preventing bending of the extended portion 204 and allowing the extended portion 204 to be housed along the axial direction of the bracket 500 on the side edge of the bracket 500, which is useful for the overall spatial layout of the device.

[0064] In an exemplary embodiment, when the first snap fit 334 is snapped into the extended portion 204, the lateral height of the extended portion 204 is smaller than the end face height of the positioning block 560 and / or the end face height of the second snap fit 550, and the end face height of the first snap fit 334 is smaller than the end face height of the positioning block 560 and / or the end face height of the second snap fit 550. In this invention, when the intake pipe 202 is engaged with the first snap fit 334, the lateral height of the extended portion 204 is smaller than the end face height of the second snap fit 550 and / or the end face height of the positioning block 560, and the end face height of the first snap fit 334 is smaller than the end face height of the positioning block 560 and / or the end face height of the second snap fit 550. Thus, when the intake pipe 202 is housed in the case 210, during the ventilation process, the intake pipe 202 will only contact the case 210, or the intake pipe 202 will not come into contact with the case 210. This prevents the intake pipe 202 from being pressed against the inner wall of the case 210 during the ventilation process, that is, it prevents the intake pipe 202 from being crushed, ensuring that the intake pipe 202 has its original ventilation space and that the ventilation of the intake pipe 202 is smooth.

[0065] Referring to Figure 28, the oral hygiene device 10 further includes a base 570, which is connected to a bracket 500, and an intake pipe 202 is connected to the base 570. An intake port 834 is provided in the capping member 830, which is provided in the shape of a hollow column, and the base 570 is connected to the capping member 830 via the intake port 834. An air supply passage is formed by the outside world, the intake port 834, and the intake pipe 202. Specifically, the air supply passage is formed by the first intake port 810, the intake port 834, and the intake pipe 202. Of these, the intake port 834 is fitted with a rubber stopper, so that the intake port 834 is sealed and connected to the base 570. The base 570 is provided with an air supply port 572, which is provided in the shape of a hollow column. When the capping member 830 and the intake pipe 202 are assembled, the air supply port 572 faces the intake port 834, the intake pipe 202 faces the air supply port 572, and the intake pipe 202 is attached around the air supply port 572. The intake port 834, the intake pipe 202, and the air supply port 572 are provided coaxially. In this application, the provision of the intake port 834 effectively ensures an airtight connection between the base 570 and the capping member 830.

[0066] Referring to Figures 29 to 35, the oral hygiene device 10 according to the fourth embodiment of the present application differs from the oral hygiene device 10 of the previously described embodiment in the following respects. In this embodiment, the oral hygiene device 10 may include, for example, a main unit 1000 and a suspension device 900.

[0067] Specifically, the suspension device 900 may be mounted on a wall, for example, and the suspension device 900 may further include, for example, a suspension fixing member 910 and a charging assembly 920, the charging assembly 920 may be mounted, for example, within the suspension fixing member 910, and the cleaning device body 1000 may be detachably mounted on the suspension fixing member 910, so that the oral cleaning device 10 is wall-mounted. After the cleaning device body 1000 is placed on the suspension fixing member 910, it becomes possible to charge the cleaning device body 1000 by, for example, electrically connecting it to the charging assembly 920. Furthermore, the suspension fixing member 910 is provided with, for example, a first positioning structure, and the cleaning device body 1000 is provided with a second positioning structure that conforms to the first positioning structure.

[0068] By mounting the cleaning device body 1000 on the suspension device 900 and electrically connecting the cleaning device body 1000 to the charging assembly 920, the user can place the cleaning device body 1000 on the suspension device 900, hang the cleaning device body 1000 on a wall, and charge the cleaning device body 1000. In this way, the cleaning device body 1000 does not occupy planar space when placed or charged, reduces collisions due to external forces, and improves the stability of the placement. Furthermore, by providing a first positioning structure and a second positioning structure, the placement of the cleaning device body 1000 on the suspension device 900 is facilitated, and the accuracy of the placement position and placement efficiency can be improved.

[0069] Referring to Figures 31 to 35, the first positioning structure may be, for example, a first magnetic attraction member 930, and the second positioning structure may be, for example, a second magnetic attraction member 940, and the first magnetic attraction member 930 and the second magnetic attraction member 940 are magnetically attracted to each other. For example, the suspension fixing member 910 has a first mounting side 912, and the cleaning device body 1000 has a second mounting side 1010 corresponding to the first mounting side 912. That is, when the cleaning device body 1000 is placed on the suspension fixing member 910, the side of the suspension fixing member 910 closer to the cleaning device body 1000 becomes the first mounting side 912, and the side of the cleaning device body 1000 closer to the suspension fixing member 910 becomes the second mounting side 1010. Specifically, the suspension fixing member 910 may include, for example, a first mounting portion 914, the first mounting portion 914 being provided in close proximity to the cleaning device body 1000, that is, the first mounting portion 914 being provided in close proximity to the first mounting side 912, the first magnetic attraction member 930 being provided on the first mounting portion 914, the first mounting portion 914 being, for example, a groove, and the first magnetic attraction member 930 being, for example, provided within the groove. The cleaning device body 1000 may include, for example, a case 210, the case 210 having a second mounting portion 212, the second mounting portion 212 being provided in close proximity to the suspension fixing member 910, that is, the second mounting portion 212 being provided in close proximity to the second mounting side 1010, the second magnetic attraction member 940 being provided on the second mounting portion 212, the second mounting portion 212 being, for example, a groove, and the second magnetic attraction member 940 being, for example, provided within the groove. By providing the first magnetic attraction member 930 and the second magnetic attraction member 940, the accuracy of the placement position and the efficiency of the placement of the cleaning device body 1000 on the suspension device 900 can be improved.

[0070] In some specific embodiments of this embodiment, the first positioning structure may be provided on the side of the suspension fixing member 910 closer to the cleaning device body 1000, that is, the first positioning structure may be provided on the first mounting side 912 of the suspension fixing member 910, and the second positioning structure may be provided on the side of the cleaning device body 1000 closer to the suspension fixing member 910, that is, the second positioning structure may be provided on the second mounting side 1010 of the cleaning device body 1000, and when the cleaning device body 1000 is positioned on the suspension fixing member 910, the first positioning structure and the second positioning structure are engaged in a concave-concave-concave relationship. For example, the first positioning structure may be, for example, a positioning groove, and the second positioning device may be, for example, a positioning projection, the positioning projection being provided in correspondence with the positioning groove, and when the cleaning device body 1000 is located on the suspension fixing member 910, the second positioning structure is housed in the first positioning structure, or, the first positioning structure is a positioning projection, the second positioning structure is a positioning groove, the positioning projection being provided in correspondence with the positioning groove, and when the cleaning device body 1000 is located on the suspension fixing member 910, the first positioning structure is housed in the second positioning structure.

[0071] The suspension fixing member 910 may be provided with, for example, a hanging portion, and the cleaning device body 1000 is provided with an engaging portion 1020 that fits the hanging portion, and when the cleaning device body 1000 is positioned on the suspension fixing member 910, the engaging portion 1020 is attached to the hanging portion. The cleaning device body 1000 may include, for example, a handle 200, the engaging portion 1020 is located at one end of the handle 200, and the handle 200 is further provided with a grip portion 220. For example, the cleaning device body 1000 may be, for example, an electric toothbrush, and the cleaning device body 1000 may include, for example, a brush head 100 and a handle 200, the engaging portion 1020 is provided on the side of the handle 200 closer to the brush head 100, and the grip portion 220 provides a certain gripping space for the cleaning device body 1000, making it easy to pick up and place the cleaning device body 1000.

[0072] Specifically, the engaging portion 1020 may be, for example, a projection provided on the cleaning device body 1000, and more specifically, it may be, for example, a cylindrical projection. The hanging portion may include, for example, two hanging members 950, the two hanging members 950 being provided opposite each other on the suspension fixing member 910, and the two hanging members 950 and the suspension fixing member 910 forming a hanging space 952, and a first spacing space 954 further formed between the two hanging members 950, the first spacing space 954 may be located, for example, in the lower part of the suspension fixing member 910 near the gripping portion 220, and when the cleaning device body 1000 is positioned on the suspension fixing member 910, the gripping portion 220 passes through the first spacing space 954 and the engaging portion 1020 is clamped within the hanging space 952. Furthermore, the two hanging members 950 may have, for example, position regulating portions 956 formed thereon, which are located, for example, below the suspension fixing member 910, and a part of the engaging portion 1020, i.e., the side of the engaging portion 1020 closer to the gripping portion 220, abuts against the position regulating portion 956. This configuration makes the placement of the cleaning device body 1000 more stable.

[0073] In one specific embodiment of this model, when the cleaning device body 1000 is positioned on the suspension fixing member 910, a movable gap is provided between the engaging portion 1020 and the inner wall of the hanging space 952. Furthermore, a hanging opening 958 is formed on the side of the hanging space 952 furthest from the suspension fixing member 910, and the hanging opening 958 provides a method for horizontally placing the cleaning device body 1000 on the suspension fixing member 910. The engaging portion 1020 is provided so as to protrude from the gripping portion 220, so that the engaging portion 1020 is hooked onto the first spacing space 954, and the gripping portion 220 passes through the first spacing space 954. A second spacing space 955 is formed between the two hooking members 950, and the first spacing space 954 and the second spacing space 955 are provided opposite each other, so that the gripping portion 220 can pass through the second spacing space 955. Furthermore, the opening width of the first spacing space 954 is smaller than the opening width of the second spacing space 955. A movable gap is provided between the engaging portion 1020 and the inner wall of the hanging space 952, allowing the engaging portion 1020 to move within the hanging space 952, making it easier to pick up the cleaning device body 1000. Furthermore, by making the opening width of the first spacing space 954 smaller than the opening width of the second spacing space 955, it becomes easier to pick up and place the cleaning device body 1000, and the stability of the placement is improved. Moreover, the first positioning structure and the second positioning structure enable the charging positioning and positioning of the cleaning device body 1000 and the suspension device 900, improving placement efficiency, and further making it easier for the user to pick up the cleaning device body 1000 and charge the cleaning device body.

[0074] In one specific embodiment of this model, the surfaces of the two hanging members 950 on the side where the first spacing 954 is formed are further provided with anti-slip pads, which are, for example, silica gel pads, and when the cleaning device body 1000 is positioned on the suspension fixing member 910, the anti-slip pads come into contact with the cleaning device body 1000, specifically, the anti-slip pads come into contact with the surface of the engaging portion 1020, and the anti-slip pads serve to protect the surface of the engaging portion 1020, thereby avoiding the problem of surface damage occurring between the engaging portion 1020 and the two hanging members 950 due to collision or friction.

[0075] The cleaning device body 1000 may include, for example, a receiving end coil 1030, and specifically, for example, the receiving end coil 1030 may be provided within the engaging portion 1020 of the cleaning device body 1000. The charging assembly 920 may include, for example, a transmitting end coil 922, which may be provided within, for example, a suspension fixing member 910, and power is supplied to the cleaning device body 1000 by electromagnetic induction between the receiving end coil 1030 and the transmitting end coil 922. The charging assembly 920 may further include, for example, a charging port 924, which may be connected to, for example, an external power line and connected to an external power source via the external power line, and the charging assembly 920 may further include, for example, a conductor, which may be connected to a circuit board in the suspension fixing member 910 and the other end may be directly connected to an external power source. The suspension fixing member 910 may further include, for example, a bracket case 916 and a charging circuit board 918, the charging circuit board 918, the charging port 924 and the transmitting end coil 922 being provided inside the bracket case 916, the charging circuit board 918, the charging port 924 and the transmitting end coil 922 being electrically connected, and the bracket case 916 may further be provided with, for example, a port through-hole corresponding to the charging port 924, and the charging port 924 is connected to an external power supply so that power is supplied to the cleaning device body 1000 by electromagnetic induction between the receiving end coil 1030 and the transmitting end coil 922.

[0076] Furthermore, the suspension fixing member 910 is further provided with a first auxiliary connection structure, and the cleaning device body 1000 is further provided with a second auxiliary connection structure. When the cleaning device body 1000 is positioned on the suspension fixing member 910, the first auxiliary connection structure and the second auxiliary connection structure are connected. The first and second auxiliary connection structures may be, for example, magnetic attraction members or snap-fit ​​members. The connection between the first and second auxiliary connection structures further improves the stability of the connection between the cleaning device body 1000 and the suspension fixing member 910.

[0077] Referring again to Figures 31 and 32, the suspension device 900 may further include, for example, a suspension mounting member 970. The suspension fixing member 910 is provided with a fixing member 960, and one side of the suspension mounting member 970 is detachably connected to the fixing member 960, while the other side of the suspension mounting member 970 is used to connect to a wall. The suspension mounting member 970 may be fixed to the wall by means of, for example, adhesive or screws, and the side of the suspension mounting member 970 closer to the fixing member 960 may be provided with, for example, a mounting projection, and the fixing member 960 may be provided with, for example, a mounting groove, and the mounting projection may be mounted, for example, within the mounting groove. Of course, the fixing member 960 and the suspension mounting member 970 may be detachably connected by means of, for example, magnetic attraction or snap-fit, but this embodiment will not be described one by one with examples again.

[0078] Referring to Figures 36 to 39, the suspension device 900 according to the fifth embodiment of the present application differs from the suspension device 900 of the previously described embodiment in the following respects. In this embodiment, the suspension fixing member 970 may be, for example, a metal member or a plastic member, and a fixing portion 972 is provided on one side of the suspension fixing member 970, and the other side of the suspension fixing member 970 is attached to a wall. Referring to Figure 37, the fixing portion 972 may include, for example, a fixing body portion 974 and a first hooking portion 976 provided on the fixing body portion 974, and the first hooking portion 976 may be provided surrounding the outer circumference of the fixing body portion 974, and the edge of the first hooking portion 976 that is separated from the fixing body portion 974 may be arranged along a circumferential trajectory. The fixing body portion 974 may be, for example, a circular structure or a triangular structure, but this embodiment is not limited thereto. Referring to Figure 39, the suspension fixing member 910 may also be made of, for example, a metal member or a plastic member. A second hooking portion 911 is provided on the side of the suspension fixing member 910 closest to the suspension fixing member 970, and the second hooking portion 911 engages with the first hooking portion 976. The second hooking portion 911 may also be hooked onto the first hooking portion 976.

[0079] In this embodiment, the suspension fixing member 970 in the suspension device 900 is provided with a fixing portion 972, and the fixing portion 972 includes a fixing body portion 974 and a first hooking portion 976 provided surrounding the outer circumference of the fixing body portion 974, and the edge of the first hooking portion 976 away from the fixing body portion 974 is arranged along a circumferential trajectory, and the suspension fixing member 910 is provided with a second hooking portion 911, and the second hooking portion 911 fits the first hooking portion 976. As a result, the edge of the first hooking portion 976 away from the fixing body portion 974 is arranged along a circumferential trajectory, so the suspension fixing member 970 can be attached to the wall at any angle, and the second hooking portion 911 on the suspension fixing member 910 can both be hooked onto the first hooking portion 976. In this way, when using the suspension device 900, the suspension fixing member 970 can be attached as desired, making operation very convenient. Furthermore, it stabilizes the suspension by the suspension fixing member 910 and maintains the correct hanging effect of the suspension fixing member 910.

[0080] Specifically, the suspension fixing member 970 may further include, for example, a mounting portion 978, which is for attachment to a wall. Adhesive may be provided on the side of the mounting portion 978 closest to the wall, and the mounting portion 978 may be attached to the wall via the adhesive, or the mounting portion 978 may be fixed to the wall by means of, for example, rivets or screws, but this embodiment is not limited thereto. The fixing portion 972 is provided so as to protrude from the mounting portion 978, that is, the fixing portion 972 protrudes in a direction away from the mounting portion 978. A housing groove 913 may be provided on the side of the suspension fixing member 910 closest to the suspension fixing member 970, and the second hooking portion 911 is provided on the side wall of the housing groove 913. When the suspension fixing member 910 is hooked onto the suspension fixing member 970, the fixing portion 972 is located within the housing groove 913, and the second hooking portion 911 is hooked onto the first hooking portion 976. When the suspension fixing member 910 is assembled onto the suspension fixing member 970, the suspension fixing member 910 is pulled downward by gravity, causing the fixing portion 972 to enter the second hooking portion 911, thereby further improving the fixing effect.

[0081] In one specific embodiment of this embodiment, one of the second latching portion 911 and the first latching portion 976 is a recessed groove and the other is a projection. The shape and dimensions of the housing groove 913 may conform to, for example, the fixing portion 972, and in some embodiments, the shape and dimensions of the housing groove 913 may be the same as, for example, the shape and dimensions of the fixing portion 972, so that the fixing portion 972 is tightly provided within the housing groove 913, the latching becomes more stable and less prone to shaking, and in some other embodiments, the shape of the housing groove 913 and the shape of the fixing portion 972 may be different, for example, the shape of the housing groove 913 may be a rectangle or a trapezoid, and the dimensions of the housing groove 913 may be larger than the dimensions of the fixing portion 972, for example, so that the fixing portion 972 is housed within the housing groove 913.

[0082] Referring to Figure 37, in this embodiment, the first hooking portion 976 is a circular structure provided surrounding the outer circumference of the fixed main body portion 974. Because the first hooking portion 976 is a circular structure provided surrounding the outer circumference of the fixed main body portion 974, the suspension fixing member 970 can be attached to the wall at any angle, and the second hooking portions 911 on the suspension fixing member 910 can all be hooked onto the first hooking portion 976.

[0083] Referring to Figures 38A and 38B, in this embodiment, there are multiple first hooking portions 976, which are provided on the fixed body portion 974 and spaced apart along the outer circumference of the fixed body portion 111. Furthermore, the multiple first hooking portions 976 may, for example, have the same structure, and the spacing between any two adjacent first hooking portions 976 may be the same, that is, the sides of the multiple first hooking portions 976 that are separated from the fixed body portion 974 may be distributed circumferentially. Since the multiple first hooking portions 976 are provided surrounding the outer circumference of the fixed body portion 974, the suspension fixing member 970 can be attached to a wall at any angle, and any of the second hooking portions 911 on the suspension fixing member 910 can be hooked onto the first hooking portions 976.

[0084] Furthermore, the length of the second latch portion 911 in the circumferential direction of the receiving groove 913 is greater than the length of the distance between any two adjacent first latch portions 976 in the circular trajectory, where the length of the second latch portion 911 is the length of the side of the second latch portion 911, i.e., the arc length, and the distance between the two first latch portions 976 is also, for example, the arc length. The length of the second latch portion 911 in the circumferential direction of the receiving groove 913 is greater than, for example, the length of each distance in the circular trajectory, that is, the length of the second latch portion 911 may be greater than, for example, the length of the maximum distance. In this way, when the distance between the two first latch portions 976 is positioned to face upward, the second latch portion 911 can also be hooked onto the two first latch portions 976 and the distance, so that the suspension fixing member 970 can be attached to the wall at any angle, and each of the second latch portions 911 on the suspension fixing member 910 can be hooked onto the first latch portions 976. Furthermore, the length of the second latching portion 911 in the circular trajectory of the housing groove 913 is greater than the length of the first latching portion 976 in the circular trajectory. For example, the length of the second latching portion 911 in the circumferential direction of the housing groove 913 is greater than the length of each of the first latching portions 976 in the circular trajectory. That is, the length of the second latching portion 911 is greater than the length of the largest first latching portion 976. In this way, when any one of the first latching portions 976 is positioned facing upward, any of the second latching portions 911 can be hooked onto the first latching portion 976. Therefore, the suspension fixing member 970 can be attached to the wall at any angle, and any of the second latching portions 911 on the suspension fixing member 910 can be hooked onto the first latching portion 976.

[0085] Referring to Figures 40 and 41, the side wall of the housing groove 913 may further be provided with, for example, a contact-release position 915, which is provided opposite the second hooking portion 911. When the first hooking portion 976 contacts the contact-release position 915, the second hooking portion 911 releases from the first hooking portion 976. In this embodiment, the housing groove 913 of the suspension fixing member 910 may be, for example, a circular structure, and the diameter of the fixing portion 972 may be, for example, equal to the diameter of the housing groove 913, but of course, this embodiment is not limited thereto. If it is necessary to detach the suspension fixing member 910 from the suspension fixing member 970, the user may, for example, pull the suspension fixing member 910 upward to bring the first latching portion 976 of the fixing portion 972 into contact with the contact / disengagement position 915. In this way, the first latching portion 976 can be detached from the second latching portion 911, making it easier to remove the suspension fixing member 910. Furthermore, the length of the second latching portion 911 in the circumferential direction is less than half the circumference of the housing groove 913. In this way, when the suspension fixing member 910 is pulled upward, the fixing portion 972 can be brought into contact with the contact / disengagement position 915, and the fixing portion 972 can be detached from the second latching portion 911, improving the convenience of removing the suspension fixing member 910.

[0086] Referring to Figures 42 to 44, the suspension device 900 according to the sixth embodiment of the present application differs from the suspension device 900 of the previously described embodiment in the following respects. In this embodiment, the suspension device 900 further includes a suspension magnetic attraction member 932.

[0087] The suspension fixing member 910 may have, for example, a wall-mounting side 917 and a charging side 919, with the wall-mounting side 917 being provided opposite the charging side 919. The wall-mounting side 917 is used for fixing to a wall, desk, dressing table, etc., and the charging side 919 is used for connecting to a device to be charged, such as an oral hygiene device 100. The first magnetic attraction member 930, the transmitting end coil 922, and the suspension magnetic attraction member 932 are all provided on the suspension fixing member 910. The first magnetic attraction member 930 and the transmitting end coil 922 are provided in the suspension fixing member 910 in close proximity to the charging side 919, and the suspension magnetic attraction member 932 is provided in the suspension fixing member 910 in close proximity to the wall-mounting side 917. The first magnetic attraction member 930 is provided in correspondence with the transmitting end coil 922 so that wireless charging can be performed after magnetic attraction connection with the device to be charged. The suspended magnetic attraction member 932 and the transmitting end coil 922 are offset from each other in a first direction, and this first direction is the direction toward the charging side 919 along the wall mounting side 917. By offsetting the suspended magnetic attraction member 932 and the transmitting end coil 922 in the first direction, the influence of the suspended magnetic attraction member 932 on the transmitting end coil 922 can be reduced. This enables wall mounting of the suspension device 900 via the suspended magnetic attraction member 932, and also ensures that heat generation during charging of the device to be charged by the transmitting end coil 922 can be reduced, thereby improving charging efficiency.

[0088] In some embodiments of this embodiment, the transmitting end coil 922 and the first magnetic attraction member 930 may be provided, for example, on the outer surface of the suspension fixing member 910, that is, the transmitting end coil 922 and the first magnetic attraction member 930 may be provided on the charging side 919 of the suspension fixing member 910 away from the wall-mounting side 917, and may be connected to the outer surface of the suspension fixing member 910 by means of, for example, adhesive or riveting. Similarly, the suspension magnetic attraction member 932 may also be provided, for example, on the outer surface of the suspension fixing member 910, specifically, for example, on the wall-mounting side 917 of the suspension fixing member 910 away from the charging side 919, and may be connected to the outer surface of the suspension fixing member 910 by means of, for example, adhesive or riveting. In some other embodiments of this embodiment, the transmitting end coil 922, the suspension magnetic attraction member 932 and the first magnetic attraction member 930 may be provided, for example, inside the suspension fixing member 910. Of course, the specific positions of the transmitting end coil 922, the suspended magnetic attraction member 932, and the first magnetic attraction member 930 on the suspension fixing member 910 can be set according to actual needs, and this embodiment is not limited to these positions.

[0089] In one embodiment of this model, the suspended magnetic attraction member 932 has a first projection on the suspended fixing member 910 along a first direction, and the transmitting end coil 922 has a second projection on the suspended fixing member 910 along a first direction, wherein the first projection may be located outside the second projection, or the second projection may be located outside the first projection. This allows the suspended magnetic attraction member 932 and the transmitting end coil 922 to be offset in the first direction, thereby reducing the influence of the suspended magnetic attraction member 932 on the transmitting end coil 922.

[0090] Furthermore, the first magnetic attraction member 930 and the suspended magnetic attraction member 932 overlap at least partially in the first direction. In this way, the influence of the first magnetic attraction member 930 and the suspended magnetic attraction member 932 on the transmitting end coil 922 can be reduced. The first magnetic attraction member 930 and the suspended magnetic attraction member 932 may be magnets or members that can be attracted by magnets, such as iron pieces. Specifically, in one embodiment of this embodiment, the first magnetic attraction member 930 may be, for example, a circular magnet and be provided at an intermediate position, and the transmitting end coil 922 may be provided surrounding the first magnetic attraction member 930, and the transmitting end coil 922 may be, for example, an annular structure, and the first magnetic attraction member 930 may be located on the inner ring of the annular structure. The suspended magnetic attraction member 932 may also be, for example, a magnet, and may be provided in correspondence with the first magnetic attraction member 930. The suspended magnetic attraction member 932 may also be, for example, a circular magnet, and may have the same shape and size as the first magnetic attraction member 930 and be provided in correspondence with it in the first direction. By making the suspended magnetic attraction member 932 and the first magnetic attraction member 930 the same shape and size and providing them in correspondence with each other in the first direction, the influence of the suspended magnetic attraction member 932 on the coil can be further reduced. Of course, the diameter of the suspended magnetic attraction member 932 may be, for example, larger than the diameter of the first magnetic attraction member 930, and the thickness of the suspended magnetic attraction member 932 in the first direction may be, for example, larger than the thickness of the first magnetic attraction member 930, but this embodiment is not limited thereto. In this way, the magnetic attraction strength of the suspended magnetic attraction member 932 can be increased and the stability of the suspension can be improved. In another embodiment of this embodiment, the suspension magnetic attraction member 932 and the first magnetic attraction member 930 may both be, for example, multiple magnets, the multiple magnets arranged in an annular structure, and two adjacent magnets have opposite magnetisms on the side facing the charging side 919, and further, positioning iron pieces may be provided on the side of the multiple magnets facing the wall-mounting side 917, which makes it easier for the multiple magnets to be arranged in an annular structure.

[0091] In another embodiment of this embodiment, the first magnetic attraction member 930 may be, for example, an annular magnet or an annular structure arranged by multiple magnets, and the transmitting end coil 922 is located on the inner ring of the annular structure of the first magnetic attraction member 930, that is, the first magnetic attraction member 930 is provided surrounding the transmitting end coil 922. The suspended magnetic attraction member 932 may also be, for example, a magnet, and the suspended magnetic attraction member 932 is provided corresponding to the first magnetic attraction member 930, and the suspended magnetic attraction member 932 may also be, for example, an annular magnet or an annular structure arranged by multiple magnets, and the suspended magnetic attraction member 932 may have the same shape and size as the first magnetic attraction member 930 and be provided correspondingly in the first direction, and of course the diameter of the suspended magnetic attraction member 932 may be, for example, larger than the diameter of the first magnetic attraction member 930, and the thickness of the suspended magnetic attraction member 932 in the first direction may be, for example, larger than the thickness of the first magnetic attraction member 930, but this embodiment is not limited thereto.

[0092] In one embodiment of this model, the first magnetic attraction member 930 has a second projection on the suspension fixing member 910 along a first direction, and the first projection may, for example, cover the second projection. The suspension magnetic attraction member 932 and the first magnetic attraction member 930 may, for example, have the same shape and be provided correspondingly in the first direction. This further reduces the influence of the suspension magnetic attraction member 932 on the coil. Specifically, the diameter of the suspension magnetic attraction member 932 may also be larger than the diameter of the first magnetic attraction member 930, for example. In this way, the magnetic attraction strength of the suspension magnetic attraction member 932 can be increased without increasing the thickness of the suspension magnetic attraction member 932, reducing its occupancy in the internal space of the suspension fixing member 910, improving the stability of the suspension, and reducing the volume of the suspension fixing member 910.

[0093] Referring again to Figures 43 and 44, the suspension device 900 may further include, for example, a magnetic shielding structure, which is provided between the transmitting end coil 922 and the suspension magnetic attraction member 932. Specifically, the magnetic shielding structure may be, for example, a first magnetic shielding member 980 or a nanocrystalline magnetic shielding sheet 990, or the magnetic shielding structure may include, for example, a first magnetic shielding member 980 and a nanocrystalline magnetic shielding sheet 990, with the first magnetic shielding member 980 and the nanocrystalline magnetic shielding sheet 990 being laminated. The first magnetic shielding member 980 may be a hard magnetic shielding member, for example, a ferrite magnetic shielding member fired at a high temperature. By providing a magnetic shielding structure between the transmitting end coil 922 and the suspension magnetic attraction member 932, the influence of the suspension magnetic attraction member 932 on the transmitting end coil 922 can be reduced, thereby improving charging efficiency. By providing the nanocrystalline magnetic shielding sheet 990, the magnetic shielding effect of the magnetic shielding structure is guaranteed, and it can be made thinner, thereby increasing the magnetic shielding effect while reducing the space it occupies inside the suspension fixing member 910, and further reducing the volume of the suspension fixing member 910.

[0094] Referring to Figure 45, the cleaning device body 1000 is provided with a receiving end coil 1030, which is connected to a transmitting end coil 922 by electromagnetic induction for wireless charging. The cleaning device body 1000 may further be provided with, for example, a second magnetic attraction member 940, a circuit board 600, and a second magnetic shielding member 1040. The receiving end coil 1030, the second magnetic attraction member 940, and the second magnetic shielding member 1040 may be provided, for example, on the outer surface of the cleaning device body 1000 near the suspension device 900, or on the side of the cleaning device body 1000 near the suspension device 900. The second magnetic attraction member 940 is provided in accordance with the structure of the first magnetic attraction member 930, the receiving end coil 1030 is provided in accordance with the structure of the transmitting end coil 922, the circuit board 600 is electrically connected to the receiving end coil 1030, and the second magnetic shielding member 1040 may be provided, for example, on the side of the receiving end coil 1030 that is away from the transmitting end coil 922. Specifically, for example, the second magnetic shielding member 1040 may be provided between the circuit board 600 and the second magnetic attraction member 940, thereby avoiding interference between the circuit board 600 and the receiving end coil 1030 and thus avoiding an impact on charging efficiency. The second magnetic shielding member 1040 may be, for example, a nanocrystalline magnetic shielding sheet, thereby increasing the magnetic shielding effect and reducing its occupation of the internal space of the cleaning device body 1000.

[0095] Referring to Figures 46 to 49, the suspension device 900 according to the seventh embodiment of the present application differs from the suspension device 900 of the previously described embodiment in the following respects. In this embodiment, the suspension device 900 may include, for example, a cleaning device body 1000, a display screen 2000, and a switch member 3000.

[0096] The display screen 2000 is provided, for example, on the main body 1000 of the cleaning device, and the switch member 3000 is provided inside the main body 1000 of the cleaning device, and the switch member 3000 may be provided on the side of the display screen 2000 that is away from the surface of the main body 1000 of the cleaning device. The display screen 2000 is provided on the handle 200 and connected to the case 210, and the display screen 2000 may be, for example, an LCD (Liquid Crystal Display), but of course it may be any other display screen, and the display screen 2000 is for displaying information such as the operating mode and / or amount of electricity of the oral cleaning device 10. The switch member 3000 is provided inside the case 210 and is located on the side of the display screen 2000 that is away from the surface of the case 210.

[0097] The display screen 2000 is provided on the cleaning device body 1000 of the oral cleaning device 10, and the switch member 3000 is provided inside the cleaning device body 1000 and on the side of the display screen 2000 that is away from the surface of the case 210. By integrating the switch member 3000 into the case 210, the switch button can be hidden. When the display screen 2000 is pressed, the switch member 3000 turns on or off in response to the pressure. This configuration enables button control and screen display, prevents water from entering the case, further reduces the possibility of water entering the case, saves space on the surface of the case 210, simplifies the structure, and by providing the switch member 3000, accidental touches due to water splashing onto the display screen during use can be avoided, improving the user experience.

[0098] Furthermore, the switch member 3000 is, for example, a pressure switch, which is provided in correspondence with the display screen 2000 and is electrically connected to the display screen 2000. When pressure is applied to the display screen 2000, the display screen 2000 deforms and generates a signal, which can be transmitted to the pressure switch. The pressure switch controls the on / off state of the oral cleaning device 10 and switches the operating mode, etc., according to the relative pressure applied to the display screen 2000. A gap may be provided between the display screen 2000 and the pressure switch. When the display screen 2000 is pressed, the surface of the display screen 2000 closest to the pressure switch comes into contact with the pressure switch, triggering the pressure switch and controlling the operation of the oral cleaning device 10 by the pressure switch. Furthermore, for example, a surface of the display screen 2000 close to the pressure switch may be in contact with a surface of the pressure switch close to the display screen 2000, and when the display screen 2000 is pressed, the pressure switch is pressed, which triggers the pressure switch, and the pressure switch controls the operation of the oral cleaning device 10.

[0099] Referring again to Figure 47, the surface of the cleaning device body 1000 is provided with a water-blocking structure 1050, which surrounds the display screen 2000, and the water-blocking structure 1050 is, for example, a projection that surrounds the display screen 2000, and the projection may protrude from the surface of the cleaning device body 1000. Specifically, the water-blocking structure 1050 is provided at the end of the handle 200 closest to the brush head 100. The watertight structure 1050 prevents water from entering the interior of the cleaning device body 1000. In particular, when a user uses the oral cleaning device 10, water flows along the brush head 100 towards the handle 200. The watertight structure 1050 guides the water towards the side edge of the handle 200, preventing it from flowing onto the display screen 2000. Furthermore, by placing the watertight structure 1050 at the end of the handle 200 closest to the brush head 100, it prevents the user from accidentally touching the display screen 2000 when gripping the handle 200 with their hand.

[0100] In one specific embodiment of this model, the display screen 2000 may be provided on, for example, the case 210, and specifically, for example, the surface of the screen body of the display screen 2000 may be exposed to the case 210. In this way, the user can view the display content on the display screen 2000 on the case 210, and the user can control the pressure of the switch member 3000 by pressing on the display screen 2000 to control the on or off of the oral cleaning device 10, and switch cleaning modes, etc.

[0101] In one specific embodiment of this model, the display screen 2000 may be provided, for example, within a case 210, and the case 210 is provided with a display area 230 corresponding to the display screen 2000. The display area 230 may be, for example, a cutout in the case 210, and the user can view the display content on the display screen 2000 through the cutout. Furthermore, referring to Figures 48 and 49, the display area 230 may be further provided with, for example, a lens 240, and the lens 240 may be, for example, made of transparent plastic or transparent glass, and by providing the lens 240, protection for the display screen 2000 can be formed. Specifically, the case 210 may be provided with, for example, a lens mounting portion 250 surrounding the display area 230, and the lens 240 may be attached to the lens mounting portion 250, which may be, for example, a groove provided in the case 210, and the lens 240 may be attached to the lens mounting portion 250 via, for example, a lens fixing member 260, which may be, for example, an adhesive member, and the lens 240 may be attached to the lens mounting portion 250 via the adhesive member, but of course the lens fixing member 260 may be, for example, a magnetic attraction member or a rivet, and this embodiment is not limited to these. By providing the lens mounting portion 250, the surfaces of the lens 240 and the case 210 can be made smoother, improving the user's feel and further enhancing the user experience. The oral hygiene device 10 may further include, for example, a decorative member 270, which may be, for example, surrounding the edge of the lens 240. The case 210 may also be further provided with, for example, a decorative member mounting section 280, and the decorative member 270 is provided on the decorative member mounting section 280. By providing the decorative member 270, the visual effect of the oral cleaning device 10 can be enhanced, and the user experience can be further improved.

[0102] Furthermore, the oral hygiene device 10 may further include, for example, a display screen protective member 1060, which may be provided, for example, surrounding the display screen 2000, with one side of the display screen protective member in contact with a switch member 3000, and the display screen protective member 1060 may be sealed and connected to the case 210, so that the switch member is triggered by the deformation of the display screen protective member 1060 when it is pressed. For example, when the lens 240 in the display area is pressed by the user, the lens 240 can, for example, contact the display screen protective member 1060, so that the display screen protective member 1060 is pressed and a slight deformation occurs, which is transmitted to the pressure switch and triggers the pressure switch. The display screen protective member 1060 may be, for example, a soft gel protective member and may be sealed and connected to the case 210 via the soft gel protective member. However, the display screen protective member 1060 may be made of another material, and the display screen protective member 1060 and the case 210 may be sealed and connected via a sealing connection member. This embodiment is not limited to this. The display screen protective member 1060 may be provided with, for example, a housing groove, and the display screen 2000 is provided in the housing groove, and the surface of the screen body of the display screen 2000 is exposed to the display screen protective member 1060. The display screen protective member 1060 may be fixed to the case 210 by, for example, rivets or screws. However, this embodiment is not limited to this. By providing the display screen protective member 1060, the display screen 2000 can be protected, and assembly is made easier. Furthermore, the sealed connection between the display screen protective member 1060 and the case 210 provides a waterproof sealing effect, further preventing water from entering the case 210 and avoiding damage to the electronic components inside the case 210 due to water.

[0103] The oral hygiene device 10 may further include, for example, a button display circuit board 1070, which may be provided on the side of the switch member 3000 away from the case 210 and connected to the case 210, and the switch member 3000 may be electrically connected to, for example, the button display circuit board 1070. The button display circuit board 1070 may be provided with, for example, mounting holes, and a fixing column is provided inside the case 210, and the button display circuit board 1070 is fixed to the fixing column through the mounting holes via fixing members such as rivets or screws, thereby fixing the button display circuit board 1070 to the case 210 and improving the stability of the button display circuit board 1070. Furthermore, the oral cleaning device 10 may further include, for example, a switch support member 1080, which is provided on the side of the button display circuit board 1070 that is farther from the display screen 2000 and is in contact with the button display circuit board 1070. The switch support member 1080 provides support when the switch member 3000 is pressed and prevents the button display circuit board 1070 from being pressed and damaged.

[0104] The oral hygiene device 10 may further include, for example, a circuit board 600, which may be provided, for example, inside a case 210, and the button display circuit board 1070 and the circuit board 600 may be electrically connected, for example, and the circuit board 600 and the switch member 3000 may be provided on opposite sides of the case 210. The case 210 may have, for example, opposing first and second side walls. Of course, the case 210 may be, for example, integrally molded, the switch member 3000 may be provided close to the first side wall, and the circuit board 600 may be provided close to the second side wall. For example, a bracket 500 is further provided inside the case 210, and electronic components such as the motor 400, airflow generator 300, and battery 700 may be provided inside the bracket 500, for example. The circuit board 600 and the switch member 3000 may be provided on opposite sides of the bracket 500, that is, an annular space is formed between the bracket 500 and the case 210, and the annular space has opposite sides, for example, the circuit board 600 may be provided on one side of the annular space, and the switch member 3000 may be provided on the other side of the annular space, but of course this is merely an illustrative explanation. By providing the circuit board 600 and the switch member 3000 on opposite sides of the case 210, damage to the circuit board 600 when the switch member 3000 is pressed can be avoided, thereby improving safety and stability. Either the button display circuit board 1070 or the circuit board 600 is further provided with an automatic switch member, which is, for example, a gyroscope, and the gyroscope is for detecting the state of the oral hygiene device 10. In this way, the oral hygiene device 10 is controlled to automatically power off.

[0105] Referring to Figures 50 to 52, the eighth embodiment of the present application provides an oral hygiene device 10 which differs from the oral hygiene device 10 of the previously described embodiment in the following respects. In this embodiment, the oral hygiene device 10 further includes a controller 610. The controller 610 may be provided, for example, on a circuit board 600 and electrically connected to a motor 400, an airflow generator 300, and a switch member 3000 via the circuit board 600. The switch member 3000 generates an operation signal in response to a pressing operation and transmits it to the controller 610, and the controller 610 controls the operation of the airflow generator 300 and the motor 400 in response to the operation signal. In the oral hygiene device 10 according to this embodiment, the operation of the airflow generator 300 and the motor 400 can be controlled by a single switch member 3000, improving the cleaning capacity, simplifying the structure, simplifying the operation procedure, and further improving the user experience.

[0106] Specifically, the display screen 2000 and the controller 610 may be electrically connected, for example, and the switch member 3000 is provided corresponding to the display screen 2000 and is electrically connected to the display screen 2000 and the controller 610, respectively. The switch member 3000 may be, for example, a pressure sensor and transmit a signal in response to a change in pressure. When pressure is applied to the display screen 2000, the display screen 2000 deforms, generating a signal, which can then be transmitted to the switch member 3000. The switch member 3000 is controlled to transmit an operation signal to the controller 610 in accordance with the relative pressure applied to the display screen 2000. A gap may be provided between the display screen 2000 and the switch member 3000, for example. When the display screen 2000 is pressed, the surface of the switch member 3000 on the display screen 2000 contacts the pressure switch, triggering the switch member 3000, which then generates an operation signal. Furthermore, for example, the surface of the display screen 2000 closest to the switch member 3000 may be in contact with the surface of the switch member 3000 closest to the display screen 2000. When the display screen 2000 is pressed, the switch member 3000 is pressed against it, triggering the switch member 3000, which then generates an operation signal.

[0107] Referring to Figure 53, the switch member 3000 may, for example, receive a user's pressing operation, generate an ON signal in response to the pressing operation, and transmit it to the controller 610. The controller 610 determines that the pressing operation is an ON signal based on the pressing time length of the pressing operation and controls it to turn on the airflow generator 300, and then controls it to turn on the motor 400 after a first predetermined time length. Specifically, if the pressing time length of the pressing operation is within a first time length range that can be, for example, greater than 0 and less than 3 seconds, the pressing operation is a short press, and the controller 610 determines that the operation signal is an ON signal. The first predetermined time length may be, for example, 0.3 seconds. When turning on the motor 400 and the airflow generator 300 to operate, the airflow generator 300 is turned on and operated first, and then the motor 400 is turned on and operated after 0.3 seconds. In this way, the airflow generator 300 can spray out food residue and dirty water from the airflow holes 112 of the brush head 100, thereby enabling the oral hygiene device 10 to self-clean.

[0108] If it is necessary to stop the operation of the oral cleaning device 10, the controller 610 may, for example, receive a stop signal and control the motor 400 to stop operation, and then control the airflow generator 300 to stop operation after a second predetermined time length. The second predetermined time length may be, for example, 0.1 seconds. When the motor 400 and the airflow generator 300 are operating and it is necessary to stop their operation, the controller 610 first controls the motor 400 to stop operation, and then controls the airflow generator 300 to stop operation after 0.1 seconds. In this way, the airflow generator 300 can spray out residual dirty water in the airflow holes 112 of the brush head 100, allowing the oral cleaning device 10 to self-clean.

[0109] During the operation of the oral cleaning device 10, that is, when the airflow generator 300 and motor 400 are turned on and operating, the controller 610 may, for example, control the display screen 2000 to display the operating mode and the amount of electricity. However, the content displayed on the display screen 2000 may be set according to actual needs, and this embodiment is not limited thereto. During the operation of the oral cleaning device 10, the controller 610 may, for example, detect the operating time, and when it detects that the operating time has reached a third predetermined time, it may control the operation of the motor 400 to stop, and after a second predetermined time, it may control the operation of the airflow generator 300 to stop. The third predetermined time may be, for example, 2 minutes, and when it detects that the operating time has reached 2 minutes, it controls the operation of the motor 400 and the airflow generator 300 to stop. By setting the third predetermined time, the oral cleaning device 10 can automatically stop operating after a certain period of time has elapsed since it started operating, and the operation of the oral cleaning device 10 can be controlled according to a scientifically appropriate brushing time, thereby ensuring a good cleaning effect.

[0110] Furthermore, during the operation of the oral purifying device 10, the switch member 3000 may, for example, receive an operation of the first switch member 3000 and generate an operation signal. In response to the operation signal, if the controller 610 determines that the time between the first pressing operation and the previous pressing operation is within the range of a second time length, the controller 610 controls the operation of the motor 400 to stop, and controls the operation of the airflow generator 300 to stop after a second predetermined time length. Of these, the range of the second time length is, for example, more than 3 seconds. That is, if the controller 610 determines that the first pressing operation was a short press and the difference in the pressing times of the two operations is more than 3 seconds, it determines that the operation signal is an operation stop signal and controls the operation of the motor 400 and the airflow generator 300 to stop. When the controller 610 controls the operation of the motor 400 and the airflow generator 300 to stop, it controls the display screen 2000 to continue displaying for 3 seconds and then automatically turn it off. Of course, this embodiment is not limited to this.

[0111] Referring to Figure 54, if the pressing time of the pressing operation is within the range of the fifth time length, the switch member 3000 generates a fluid generator on / off state switching signal in response to the pressing operation, and the controller 610 switches the on / off state of the airflow generator 300 in response to the fluid generator on / off state switching signal. The range of the fifth time length may be, for example, 5 seconds or more, and if the pressing time of the pressing operation is 5 seconds or more, the controller 610 may, for example, consider the operation signal to be a fluid generator on / off state switching signal and switch the on / off state of the airflow generator 300.

[0112] The oral purifying device 10 may further include, for example, a battery 700, which is provided inside the purifying device body 1000. The controller 610 may further determine, for example, whether the oral purifying device 10 is charging the battery 700, and control the display screen 2000 to display the charging status or the fully charged status. When the switch member 3000 is briefly pressed after or during charging, the controller 610 may control the display screen 2000 to display the charging status for 5 seconds and then turn it off. Also, for example, when charging is stopped, the controller 610 may control the display screen 2000 to display the charging status for 5 seconds and then turn it off. Furthermore, for example, when the battery is fully charged, or after charging has been restarted and the battery is fully charged again, when the switch member 3000 is briefly pressed, the controller 610 may control the display screen 2000 to display the charging status for 5 seconds and then turn it off. Of course, this embodiment is not limited thereto.

[0113] During charging, the switch member 3000 may enter factory mode if, for example, it receives a press operation and the pressing time of the press operation is within the range of the fifth time length (for example, it may be 5 seconds or more). The controller 610 then controls the motor 400 to vibrate for 0.5 seconds for feedback to inform the user that factory mode has been entered. After entering factory mode, self-test parameters may be displayed, for example. The switch member 3000 may be pressed again, for example, and the controller 610 may identify the number of presses in the first 3 seconds. If the number of presses in 3 seconds is 1, the controller 610 may control the language to switch, control the motor 400 to vibrate for 0.5 seconds for feedback, and control the display screen 2000 to display the switched language for 7 seconds before turning it off. The languages ​​may include two types, for example, Chinese and English. If the number of presses in 3 seconds is 2, the controller 610 may consider the operation signal to be an on / off state switching signal for the fluid generator, and switch the on / off state of the airflow generator 300. The controller 610 may control the motor 400 to vibrate twice for feedback, with each vibration lasting 0.5 seconds and the interval between the two vibrations being 0.5 seconds. The controller 610 may control the display screen 2000 to display the switched on / off state for 7 seconds before turning it off. Of course, the time range, predetermined time length, and display time length of the display screen 2000 in this embodiment can all be set according to actual needs, and the above numerical values ​​in this embodiment are merely illustrative and not limited to them.

[0114] In one embodiment of this system, when the motor 400 and airflow generator 300 are turned on and in operation, the controller 610 may, for example, detect that the operating time has reached a fourth predetermined time length, control the operation of the motor 400 and airflow generator 300 to pause for a fifth predetermined time length before resuming operation. The fourth predetermined time length may be, for example, 30 seconds, and the fifth predetermined time length may be, for example, 0.5 seconds. That is, during the operation of the motor 400 and airflow generator 300, the motor 400 can be paused for 0.5 seconds every 30 seconds, controlled to vibrate, prompt the user to change the toothbrushing area, and, in conjunction with the feedback to the user from the vibration of the motor 400, the user experience can be improved.

[0115] In one embodiment of this model, when the controller 610 controls the motor 400 and the airflow generator 300 to stop operation, the controller 610 may further identify and save operating modes within the range of continuous operation duration before the oral hygiene device 10 stops operating. The range of continuous operation duration may be, for example, more than 5 seconds. That is, the controller 610 may save an operating mode in which the continuous operation duration duration before stopping operation is more than 5 seconds, and then operate the device in this operating mode when it is turned on next time.

[0116] Referring to Figure 55, the switch member 3000 generates the operation signal in response to the second pressing operation, and the controller 610, in response to the operation signal, determines that the time length between the second pressing operation and the previous pressing operation is within the range of a third time length, and switches the operating mode. The range of the third time length may be, for example, greater than 0 and less than 3 seconds, and if the interval between the two pressing operations is less than 3 seconds, the controller 610 determines whether the pressing time length of the second pressing operation is less than 3 seconds, and if it is less than 3 seconds, switches the operating mode.

[0117] In one embodiment of this model, the operating modes may include, for example, a gentle mode, a cleaning mode, and a whitening mode. Of these, the gentle mode may prioritize ensuring a comfortable user experience, with the amplitude, force, and airflow rate being about 50% of that of the cleaning mode, and the operating time being 60 days or more. The motor drive parameters may be, for example, 130Hz and 70%, and the fluid generator parameters may be, for example, airflow rate ≥ 500mL ± 20% (≒ 1.8V). The cleaning mode may prioritize ensuring a cleaning experience during use, with a strong amplitude and cleaning effect. The airflow rate may be, for example, 700-800ml / min, the noise level about 55dB, and the operating time being 30 days or more. The motor parameters may be, for example, 180Hz and 90%, and the fluid generator parameters may be, for example, airflow rate ≥ 800mL ± 20% (≒ 2.5V). The whitening mode may operate intermittently, prioritizing, for example, a better cleaning effect, and may maximize the amplitude and airflow. The parameters of the motor 400 may be, for example, 180Hz, 30% and 130Hz, 90% in alternating cycles every 50ms. The parameters of the fluid generator may be, for example, airflow ≥ 1L ± 20% (≒ 3.2V). Of course, this is merely an illustrative description, and this embodiment is not limited thereto.

[0118] If the motor 400 and the airflow generator 300 are not operating and the pressing time of the pressing operation is within the range of the fourth time length, the switch member 3000 generates a travel lock on signal or a travel lock off signal in response to the pressing operation and transmits it to the controller 610, and the controller 610 turns the travel lock on or off in response to the travel lock on signal or travel lock off signal. For example, the range of the fourth time length may be, for example, more than 3 seconds, and if the interval between two pressing operations is less than 3 seconds, the controller 610 determines that the pressing time of the second pressing operation is more than 3 seconds and turns the travel lock on or off. If the travel lock is off, the controller 610 turns the travel lock on in response to the second pressing operation, and if the travel lock is on, the controller 610 turns the travel lock off in response to the second pressing operation. By providing a travel lock, it is possible to prevent the oral hygiene device 10 from being accidentally touched and turned on and activated during transport or carrying.

[0119] In one embodiment of this design, the controller 610 may be further used to control the motor 400 to vibrate and provide feedback to the user, for example, in response to an operating signal from the switch member 3000. The display screen 2000 displays the amount of electricity, charge status, travel lock status, or operating mode under the control of the controller 610, and its specific display content, display time, etc., can be set, for example, according to actual needs.

[0120] In one embodiment of this model, the oral cleaning device 10 may further include, for example, a temperature detection module, which is electrically connected to the controller 610. The temperature detection module detects the temperature of the battery 700 and, if it determines that the temperature is within an abnormal range, controls the motor 400 and the airflow generator 300 not to operate and prevents the battery 700 from charging. The temperature detection module includes, for example, an NTC thermistor. The normal temperature range may be, for example, 0 to 45°C during the charging process and -10°C to 60°C during the discharging process. If the temperature exceeds this normal range, it is considered abnormal.
