Detailed Implementation

[0032] The core of this utility model is to provide an electric toothbrush assembly whose structural design enables it to meet the user's needs for storage, charging, and hygiene.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This application provides an electric toothbrush assembly; please refer to [link / reference]. Figures 1 to 5 The electric toothbrush assembly includes an electric toothbrush body 100 and a charging base 200.

[0035] Among them, such as Figure 5 As shown, the electric toothbrush body 100 includes a grip portion 120 and a brush head 110. The brush head 110 is plugged into the grip portion 120, that is, the drive end of the motor core inside the grip portion 120 extends out of the grip portion 120, and the brush head 110 is plugged into the drive end so that the brush head 110 is replaceable. A power receiving module is provided inside the grip portion 120. The power receiving module includes a first rechargeable battery and a wireless charging receiver module. The wireless charging receiver module is electrically connected to the first rechargeable battery. The first rechargeable battery is used to power the motor core. The wireless charging receiver module is usually located at the end of the grip portion 120 away from the brush head 110.

[0036] Please see Figure 5 The brush head 110 has a plug-in connection end and a bristle end at its two ends. The plug-in connection end is used to engage with the grip part 120, and the bristle end is used to clean teeth.

[0037] The electric toothbrush body 100 is also provided with a switch button for controlling the opening and closing of the motor core and / or a mode button for adjusting the working mode of the motor core. The switch button can be configured to turn on the motor core when the switch button is pressed and immediately released, and turn off the motor core when the switch button is pressed and held for a preset time. One or more mode buttons can be set. The mode buttons can be used to control the vibration amplitude and / or vibration frequency of the motor core to form different brushing modes for the user to choose from.

[0038] It should be noted that the drive end of the motor core, the switch button, the mode button, and the grip 120 are all waterproof to prevent water from entering during brushing or when the user cleans the electric toothbrush body 100, which could affect the lifespan of the motor core and the first rechargeable battery.

[0039] The grip portion 120 is cylindrical in shape for easy gripping by the user, and the end of the grip portion 120 connected to the brush head 110 tapers in size perpendicular to the length direction of the grip portion 120 to achieve a smooth transition with the brush head 110.

[0040] The charging base 200 is provided with a receiving cavity, which is closed in the circumference and bottom, and a placement opening 300 is formed at the top. The placement opening 300 is used to insert the electric toothbrush body 100 into the receiving cavity. It should be noted that the diameter of the placement opening 300 should not be less than the larger size of the grip part 120 and the brush head 110, so that the receiving cavity is configured to be able to be inserted and fitted with the brush head 110 and the grip part 120 respectively, so that at least a part of the electric toothbrush body 100 is located in the receiving cavity. That is, after the electric toothbrush body 100 is inserted into the receiving cavity, a part can be exposed outside the receiving cavity, or it can be completely inserted into the receiving cavity.

[0041] The charging base 200 is equipped with a charging module and a disinfection and sterilization module. The charging module is compatible with the power receiving module. The charging base 200 is configured to disinfect the brush head 110 when it is inserted into the receiving cavity, and to charge the power receiving module when the grip 120 is inserted into the receiving cavity.

[0042] In this application, the charging module includes a wireless charging transmitter module, which is adapted to a wireless charging receiver module in the power receiving module. When the wireless charging transmitter module is powered on, the wireless charging receiver module charges the wireless charging receiver module through electromagnetic induction when the wireless charging transmitter module is close to the wireless charging transmitter module.

[0043] As those skilled in the art will understand, the wireless charging transmitter module includes a transmitting coil, and the wireless charging receiver module includes a receiving coil. When the transmitting coil is energized, it generates a changing magnetic field. When the receiving coil senses the change in the magnetic field, it generates a current, thereby realizing the transfer of electrical energy between the wireless charging transmitter module and the wireless charging receiver module.

[0044] The wireless charging transmitter and receiver modules use electromagnetic induction for charging, which avoids exposed metal contacts between the charging base 200 and the electric toothbrush body 100, thus preventing rusting. Furthermore, electromagnetic induction charging does not require direct contact-to-contact connection; the wireless charging transmitter and receiver modules only need to be close to a preset distance. This reduces the precision requirements on the mating structure between the electric toothbrush body 100 and the charging base 200, making it easier for users to place the electric toothbrush body 100 inside the charging base 200.

[0045] In order to enable power to the wireless charging transmitter module, the charging module may also include a line connector for connecting to an external power source, which generally refers to AC power. This line connector is electrically connected to the wireless charging transmitter module.

[0046] Of course, the charging module may also include a second rechargeable battery. The second rechargeable battery is electrically connected to the line connector and the wireless charging transmitter module respectively. When the line connector is connected to an external power source, it can supply power to both the wireless charging transmitter module and the second rechargeable battery at the same time. When the line connector is disconnected from the external power source, the second rechargeable battery supplies power to the wireless charging transmitter module.

[0047] It should be noted that the energy storage capacity of the second rechargeable battery should generally be greater than that of the first rechargeable battery.

[0048] When the user inserts the handle 120 of the electric toothbrush body 100 downwards into the receiving cavity, the charging module senses the power receiving module inside the handle 120 and charges the power receiving module of the electric toothbrush assembly. When the user inserts the brush head 110 of the electric toothbrush body 100 downwards into the receiving cavity, the disinfection and sterilization module can disinfect the brush head 110. Of course, the disinfection and sterilization module can also disinfect the handle 120 when it is inserted into the receiving cavity. It can be seen that the charging base 200 in the above-mentioned electric toothbrush assembly integrates storage, charging and hygiene cleaning functions, meets the needs of users and the market, and has good practical value.

[0049] Please see Figure 4 In order to facilitate cooperation with the grip 120 and the brush head 110 respectively, in one embodiment of this application, the bottom of the receiving cavity is provided with a charging slot 211 that can be adapted to at least one end of the grip 120 away from the brush head 110. The wireless charging transmitter module in the charging module is disposed in the charging base 200 corresponding to the position of the charging slot 211. The charging slot 211 is adapted to at least one end of the grip 120 away from the brush head 110. Adaptation means that the outline of the charging slot 211 matches the outline of the end of the grip 120 away from the brush head 110, or the size is larger than the end of the grip 120 away from the brush head 110. In this application, the outline and size of the charging slot 211 are adapted to the end of the grip 120 away from the brush head 110 so that the electric toothbrush body 100 can remain stable after the grip 120 is inserted into the charging slot 211.

[0050] Because the size of the brush head 110 is usually smaller than the size of the end of the grip 120 away from the brush head 110, the bottom of the charging groove 211 is recessed to form a disinfection groove 212. That is, the size of the disinfection groove 212, especially the cross-sectional size, is usually smaller than the size of the charging groove 211. The disinfection groove 212 can at least accommodate the bristle portion of the brush head 110. A stepped surface is formed between the disinfection groove 212 and the charging groove 211 for contacting and engaging with the end face of the grip 120 away from the brush head 110.

[0051] It should be noted that when inserting the brush head 110 of the electric toothbrush body 100 into the receiving cavity, it is not necessary to align the brush head 110 with the sterilization slot 212 every time. When sterilization and charging are not required, the brush head 110 can also be inserted into the charging slot 211 to facilitate the user's placement of the electric toothbrush body 100.

[0052] Please continue reading. Figure 4 In one specific embodiment of this application, the disinfection and sterilization module includes one or more UV (Ultra-Violet Ray) germicidal lamps. The UV germicidal lamps 600 utilize ultraviolet light of appropriate wavelengths to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms, causing growth cell death and / or regenerative cell death, thereby achieving the effect of sterilization and disinfection. The UV germicidal lamps 600 are disposed on the bottom wall and / or circumferential wall of the disinfection tank 212.

[0053] It is foreseeable that a humid environment will promote the growth of bacteria. The brush head 110 will inevitably come into contact with water during brushing. Since water easily accumulates on the bristles of the brush head 110, it is difficult for users to clean the water off the bristles. After the bristles are inserted into the disinfection tank 212, water will be carried into the disinfection tank 212, thus creating a humid environment. As a result, the bristles of the brush head 110 are always in a humid environment. In order to dry the bristles of the brush head 110 and inhibit bacterial growth, in one embodiment of this application, a drying module is also provided in the charging base 200. The drying module includes an exhaust fan and an air duct structure. One end of the air duct structure is connected to the outside of the charging base 200, and the other end is connected to the disinfection tank 212 and / or the charging tank 211. The exhaust fan is set on the air duct structure. When the exhaust fan is started, it can form a flowing airflow from the disinfection tank 212 and / or the charging tank 211 to the outside of the charging base 200.

[0054] During application, when the charging base 200 detects that the brush head 110 has been inserted into the receiving cavity, or when the user inputs a command to the charging base 200, the exhaust fan starts to dehumidify. The charging base 200 detects the brush head 110 through an infrared sensor. When the infrared sensor detects that the electric toothbrush body 100 has been inserted into the receiving cavity and the wireless charging transmitter module has not sensed the wireless charging receiver module, it means that the user has inserted the brush head 110 into the receiving cavity. At this time, the drying module and / or the disinfection and sterilization module can be activated.

[0055] Please see Figures 1 to 4In this application, in order to facilitate the cleaning of the charging slot 211 and the disinfection slot 212, the charging base 200 adopts a split structure, including a lower base compartment 210 and an upper base compartment 220 detachably connected to the lower base compartment 210. The detachable connection between the lower base compartment 210 and the upper base compartment 220 includes, but is not limited to, snap-fit ​​and threaded connection. The lower base compartment 210 and the upper base compartment 220 cooperate to form a receiving cavity. The charging slot 211, the disinfection slot 212, the charging module and the disinfection and sterilization module are all disposed in the lower base compartment 210, and the placement opening 300 is disposed in the upper base compartment 220. The inner wall of the upper base compartment 220 is provided with a reflective coating that can reflect ultraviolet rays. The reflective coating can reflect ultraviolet rays, which not only prevents ultraviolet rays from leaking out, but also improves the disinfection effect.

[0056] To ensure that the placement opening 300 on the upper compartment 220 of the base can be aligned with the charging slot 211 and the disinfection slot 212 on the lower compartment 210 of the base, a foolproof mating structure is provided between the upper compartment 220 and the lower compartment 210. That is, a concave-convex mating structure offset from the axis of the two is provided on the mating surface of the upper compartment 220 and the lower compartment 210, or multiple unevenly distributed concave-convex mating structures are provided circumferentially on the mating surface of the upper compartment 220 and the lower compartment 210 of the base, so that the upper compartment 220 and the lower compartment 210 can only be mated according to a predetermined relative position, ensuring that the placement opening 300 is aligned with the charging slot 211 and the disinfection slot 212.

[0057] To prevent the disinfection and sterilization module from being accidentally activated when the lower compartment 210 and the upper compartment 220 are separated, thus causing ultraviolet leakage, in this application, the lower compartment 210 is equipped with a triggering device. The triggering device is configured to be activated when the upper compartment 220 is connected to the lower compartment 210. When the triggering device is activated, the disinfection and sterilization module can be powered on. If the triggering device is not activated, the circuit of the disinfection and sterilization module is disconnected. The triggering device includes, but is not limited to, a proximity switch and a magnetic switch.

[0058] like Figures 1 to 3 As shown, a control device 400 for controlling the switch of the disinfection and sterilization module is provided on the outer surface of the lower compartment 210 of the base. The control device 400 includes, but is not limited to, a touch screen and physical buttons. Of course, the control device 400 can also be equipped with a voice module for voice control.

[0059] In this application, the control device 400 is a physical button with a lighting module. The lighting module is configured to emit a preset lighting effect when the disinfection and sterilization module is turned on, so as to prompt the user that the disinfection and sterilization module is running.

[0060] It is foreseeable that after a period of use, the bristles of brush head 110 will become damaged, reducing its cleaning effectiveness and potentially damaging the gums. Therefore, brush head 110 needs to be replaced regularly. Users usually purchase several spare brush heads 500. For convenient storage of spare brush heads 500, please refer to [link / reference]. Figure 3 and Figure 4 In one embodiment of this application, the lower compartment 210 of the base is further provided with a placement groove 213 at the bottom of the receiving cavity. The placement groove 213 is used to place the spare brush head 500. When the upper compartment 220 of the base is installed on the lower compartment 210 of the base, the spare brush head 500 is completely covered inside, so that the spare brush head 500 is in a relatively closed receiving cavity, which avoids the spare brush head 500 from being contaminated, does not occupy extra space, and is not easy to lose. When it is necessary to replace the brush head 110, the charging base 200 can be opened and the spare brush head 500 can be taken out for replacement.

[0061] To facilitate the placement of the electric toothbrush body 100 into the receiving cavity, the placement opening 300 of the receiving cavity and / or the circumferential sidewall of the receiving cavity are provided with a guide surface structure that cooperates with the brush head 110 and the grip part 120 of the electric toothbrush body 100. This guide surface structure guides the electric toothbrush body 100 when the user places it into the receiving cavity. The guide surface structure is preferably symmetrical, so that while guiding, it can also play a certain guiding role, allowing the user to place the electric toothbrush body 100 into the receiving cavity in a predetermined position, and preventing the electric toothbrush body 100 from being placed in the receiving cavity in an overly uniform posture, making it convenient for users, especially young users.

[0062] For example, in this application, the outlines of the placement opening 300 of the receiving cavity and the charging slot 211 are both symmetrical six-petal plum blossom shapes, which can not only play a certain guiding and limiting role, but also guide the user to place the electric toothbrush body 100 in the receiving cavity according to the predetermined position.

[0063] To further optimize the above technical solution, in order to better prevent ultraviolet leakage and facilitate user operation, in one embodiment of this application, a push-press self-locking mechanism is provided at the bottom of the disinfection tank 212. The push-press self-locking mechanism is configured to switch between a first position and a second position when pushed by the brush head 110.

[0064] For example, the push-button self-locking mechanism includes a main body, a movable part, an elastic element, and a limiting rod. The movable part is disposed on the main body and can reciprocate between a first position and a second position via the elastic element. The main body can be an integral structure with the charging base 200, or the main body and the charging base 200 can be separate structures, but the movable part is fixedly disposed on the charging base 200. The movable part is provided with a first V-shaped guide structure and a second V-shaped guide structure. The end of the first V-shaped guide structure facing the second V-shaped guide structure is provided with a first V-shaped guide surface. The end of the second V-shaped guide structure facing the first V-shaped guide structure is provided with a second V-shaped guide surface. The end of the second V-shaped guide structure facing away from the first V-shaped guide structure is provided with a third V-shaped guide surface. The first V-shaped guide surface and the second V-shaped guide surface cooperate to form a V-shaped guide groove. The tips of the first V-shaped guide surface, the tips of the second V-shaped guide surface, and the tips of the third V-shaped guide surface are all sequentially offset. The limiting rod is elastically disposed on the charging base 200.

[0065] In the initial state, the limiting rod is located outside the V-shaped guide groove. When the moving part is pushed by the brush head 110, the third V-shaped guide surface first contacts and engages with the limiting rod. Under the action of the third V-shaped guide surface, it moves towards the first end slot of the V-shaped guide groove. After reaching the first end slot position, it enters the V-shaped guide groove from the first end slot under its own elastic force and moves along the second V-shaped guide surface to the tip position of the second V-shaped guide surface. At this time, the moving part remains in the pressed position.

[0066] When the moving part is pushed again, the first V-shaped guide surface moves towards the limiting rod. Since the tip of the first V-shaped guide surface deviates from the tip of the second V-shaped guide surface, the limiting rod moves along the second end slot of the V-shaped guide surface towards the second end slot of the V-shaped guide groove under its own elastic force and the pushing action of the first V-shaped guide surface until it disengages from the V-shaped guide groove from the second end slot. At this time, the moving part disengages from the limiting rod and can pop out under the action of the elastic element, returning to the initial position.

[0067] In summary, when the push-button self-locking mechanism is in the first position, the bristles of the brush head 110 are completely within the disinfection tank. When the push-button self-locking mechanism is in the second position, at least a portion of the bristles of the brush head 110 retracts from the disinfection tank. Thus, the push-button self-locking mechanism can function as a switch for the disinfection module, allowing the user to clearly distinguish between disinfection and non-disinfection states through touch and visual inspection. It should be noted that the push-button self-locking mechanism is not a mandatory component.

[0068] To further optimize the above technical solution, in order to prevent the user from removing the electric toothbrush body 100 from the receiving cavity during the disinfection process, the charging base 200 is also provided with a clamping mechanism. The clamping end of the clamping mechanism extends into the receiving cavity. The clamping mechanism is configured to clamp the grip part 120 and / or the brush head 110 when the push-type self-locking mechanism is in the first position, and to release the grip part 120 and / or the brush head 110 after the disinfection and sterilization module completes the disinfection process.

[0069] It should be noted that when the charging base 200 does not have a push-button self-locking mechanism, a clamping mechanism can also be installed. The clamping mechanism is used to clamp when the disinfection and sterilization module receives the opening command and to release after the disinfection and sterilization process of the disinfection and sterilization module is completed.

[0070] The aforementioned push-press self-locking mechanism requires the user to push it again after disinfection to pop out the electric toothbrush body 100. To enable the electric toothbrush body 100 to pop out automatically, in one embodiment of this application, the charging base 200 is also provided with a pop-out drive mechanism. The pop-out drive mechanism is in transmission cooperation with the push-press self-locking mechanism, that is, the pop-out drive mechanism is in one-way transmission cooperation with the aforementioned limiting rod. In other words, the limiting rod can only be driven by the pop-out drive mechanism in one direction. The pop-out drive mechanism is configured to drive the push-press self-locking mechanism to switch from the first position to the second position after the disinfection and sterilization module completes the disinfection process and the clamping mechanism releases the grip 120 and / or the brush head 110. In this way, the electric toothbrush body 100 can be automatically popped out after disinfection, which is convenient for the user to use. The change in position of the electric toothbrush body 100 relative to the charging base 200 before and after disinfection also visually reminds the user that disinfection is complete.

[0071] like Figure 2 , Figure 3 and Figure 5 As shown, to enhance the fun and increase the willingness of young users to brush their teeth, in one embodiment of this application, the end of the grip 120 away from the brush head 110 is provided with a first decorative part 121 and a second decorative part 122 in order of distance from the brush head 110. The second decorative part 122 is used to block the placement opening 300 when the push-type self-locking mechanism is in the first position and to smoothly transition with the outer surface of the charging base 200. The first decorative part 121 is used to extend at least partially from the placement opening 300 to the outside of the receiving cavity when the push-type self-locking mechanism is in the second position. The first decorative part 121 includes, but is not limited to, animal shapes and anime character shapes. The shapes of the second decorative part 122 and the charging base 200 can be combined with the first decorative part 121 to form a contextualized design.

[0072] For example, such as Figures 1 to 5As shown, the charging base 200 is eggshell shaped. To maintain the stability of the charging base 200, multiple support legs 230 are also provided along the circumference of the lower part of the charging base 200. The second decorative part 122 is eggshell fragment shaped, and the first decorative part 121 is oviparous animal shaped, including birds, reptiles, etc. In the illustrated embodiment, the first decorative part 121 is dinosaur head shaped. Correspondingly, the grip part 120 is also provided with a third decorative part 123 in the shape of oviparous animal legs, which can serve as decoration, prevent slipping, and define a suitable grip position.

[0073] Furthermore, by cooperating with the aforementioned push-button self-locking mechanism, the second decorative part 122 can completely seal the placement opening 300 of the charging base 200 during the disinfection process, making the receiving cavity a completely sealed structure to prevent ultraviolet rays from leaking out. At the same time, the charging base 200 forms a complete eggshell shape in appearance. After the disinfection is completed, the push-button self-locking mechanism pops out the electric toothbrush body 100, forming the shape of an oviparous animal hatching from its shell, which increases the fun and enhances the user's willingness to use the electric toothbrush components and store the electric toothbrush body 100.

[0074] It should be noted that the shapes of the charging base 200, the first decorative part 121 and the second decorative part 122 are not limited to the above-described structures. The charging base 200 can also be shaped like a building, a seashell or the like. Correspondingly, the first decorative part 121 and the second decorative part 122 can adopt matching shapes, which are not limited here.

[0075] To prevent water accumulation and bacterial growth in the disinfection tank 212, in one embodiment of this application, a drainage structure communicating with the disinfection tank 212 is provided in the charging base 200. The stepped surface is inclined relative to the horizontal plane, and the position where the stepped surface connects with the disinfection tank 212 is the lowest point of the stepped surface, so as to facilitate the drainage of water brought into the receiving cavity by the electric toothbrush body 100.

[0076] To enhance the fun and guide younger users, in one embodiment of this application, the grip 120 and / or charging base 200 are provided with a fun guidance module. The fun guidance module is configured to emit sound and / or light prompts. For example, the fun guidance module can be a speaker installed on the grip 120 and / or charging base 200, or it can be a display screen installed on the charging base 200. When the user uses the electric toothbrush assembly, it emits sound, light, or images to guide the user in using the electric toothbrush assembly.

[0077] Furthermore, when the charging base 200 detects that the electric toothbrush body 100 has left the charging base 200, the fun guidance module begins to play pre-stored sound and / or light information to guide the user in brushing, increasing the fun and willingness to brush, and also allowing the user to control the brushing time to avoid brushing for too short a time, which would affect the brushing effect. When the charging base 200 detects that the electric toothbrush body 100 has been inserted into the charging base 200, the fun guidance module stops playing sound and / or light information.
