Description

Technical Field

[0001] The present invention belongs to the field of daily necessities and relates to a personal care product, in particular to an electric toothbrush. Background Art

[0002] As people's living standards improve, the popularity of electric toothbrushes is getting higher and higher, and the quality requirements for electric toothbrushes are also getting higher and higher. The key factor affecting the quality and service life of electric toothbrushes is the waterproof effect of the electric toothbrush shell.

[0003] Existing electric toothbrush housings are typically molded using a top-and-bottom mold structure, consisting of an upper cover, a lower cover, and a main housing. The housing typically has one or two button holes. The waterproofing process for these toothbrush housings is complex, but the effectiveness is limited, providing only a short-term, relatively good waterproofing effect. Over time, as the housing plastic and waterproof seals age and the waterproof glue loses effectiveness, the waterproofing effectiveness rapidly declines, allowing water to enter the housing. Once water enters the housing, the circuit board and electronic components of the electric toothbrush are damaged, ultimately ending the lifespan of the electric toothbrush. Furthermore, these toothbrush housings have mold parting lines, requiring a surface painting process to achieve an aesthetically pleasing finish. Some also require additional decorative and rubberized coating. This surface treatment process is not only complex and costly, but also ineffective over time. After a period of use, the surface will fade due to wear, and the aging of the rubberized plastic will cause mold to form on the flange and the surface of the rubberized plastic, causing the entire toothbrush to lose its luster and appear worn.

[0004] Therefore, it is necessary to propose a new electric toothbrush structure to overcome the problem that the existing electric toothbrush housing has poor waterproof effect and thus causes a short service life of the toothbrush. Summary of the Invention

[0005] The purpose of the present invention is to provide a new type of electric toothbrush to solve the problem that the existing electric toothbrush housing has poor waterproof effect and thus causes a short service life of the toothbrush.

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] One of the purposes of the present invention is to provide a new type of electric toothbrush to solve the problem that the existing electric toothbrush housing has poor waterproof effect and thus causes a short service life of the toothbrush.

[0048] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Example 1

[0050] like Figures 1 to 4 As shown, this embodiment provides an electric toothbrush 100, which mainly includes a handle housing 1, a power component 2 and a brush head 3. The handle housing 1 includes an integrally formed lower shell 11, and one end of the lower shell 11 is closed and the other end is open. The open end of the lower shell 11 is provided with a sealing cover 12, and the sealing cover 12 is sealed and connected to the lower shell 11; the power component 2 is arranged in the handle housing 1, and includes a vibration motor 21 and a circuit board 22 electrically connected to the vibration motor 21. The circuit board 22 is provided with a touch-sensitive button 23, and the touch-sensitive button 23 can Control the opening and closing of the vibration motor 21; the shell wall of the lower shell 11 can serve as the sensing end of the touch-sensitive button 23; the output shaft 211 of the vibration motor 21 passes through the sealing cover 12 and extends out of the sealing cover 12, and the output shaft 211 and the sealing cover 12 are sealed; the brush head 3 is connected to the output shaft 211, and after the brush head 3 and the output shaft 211 are installed in place, the brush head 3 and the sealing cover 12 are neatly docked to ensure that the brush head 3 and the sealing cover 12 are matched in appearance, and the vibration wave of the vibration motor 21 is transmitted to the top of the brush head 3 through the output shaft 211.

[0051] In this embodiment, the lower shell 11 is a transparent plastic shell; the inner wall of the transparent plastic shell is coated with a paint coating. The above-mentioned transparent plastic shell is preferably made of highly transparent and environmentally friendly PC plastic integrally injected, and its molding mold adopts a deep pull-out structure so that there is no mold parting line in the middle of the shell. The sealing cover 12 is a transparent plastic sealing cover 12; the outer surface of the transparent plastic sealing cover 12 is coated with a UV coating layer. The above-mentioned UV coating layer adopts a UV coating process, and a variety of colors are available, which brightens the color of the entire electric toothbrush shell and caters to the preferences of more consumers; at the same time, the surface treatment of the lower shell 11 of the electric toothbrush 100 adopts an inner wall spraying process. Due to the high transparency of the material of the lower shell 11 itself, the color of the paint coating is transparent from the inside to the outside without distortion or discoloration, and the coating is prevented from being worn by external friction, which can not only keep the color of the lower shell 11 long-lasting, but also keep the material of the lower shell 11 itself smooth and warm.

[0052] In this embodiment, the lower edge of the outer wall of the sealing cover 12 is provided with a double groove structure, namely a first groove structure 121 and a second groove structure 122, and the upper edge of the inner wall of the lower shell 11 is provided with a convex groove structure. The above-mentioned first groove structure 121 is a female groove for buckling with the lower shell 11, and the convex groove structure is a male groove for buckling with the sealing cover 12. The sealing cover 12 and the lower shell 11 are buckled together through the convex groove structure, which constitutes the handle shell 1 of the electric toothbrush 100. At the same time, a waterproof sealing ring 4 is placed in the second groove structure 122 located on the side of the first groove structure 121 away from the lower shell 11, so that a seal can be formed between the sealing cover 12 and the upper edge of the inner wall of the lower shell 11 after the sealing cover 12 and the lower shell 11 are buckled together, completing the waterproof work of the entire handle part of the electric toothbrush, and the buckling structure (or so-called "snap-in structure") between the sealing cover 12 and the lower shell 11 enables the assembly of the entire electric toothbrush 100 to be completed without using any screws, and is convenient for disassembly and assembly. At the same time, one end of the lower shell 11 is generally in a closed state, which reduces the waterproof sealing link at the tail of the traditional lower shell and can meet higher waterproof requirements.

[0053] In this embodiment, the sidewall of the lower housing 11 is partially recessed to form a touch-sensitive operating interface 111, and the touch-sensitive buttons 23 are located on the inner side of the touch-sensitive operating interface 111. The touch-sensitive operating interface 111 is generally a circular concave structure, and its outer surface is provided with a switch button prompt pattern for user identification.

[0054] In this embodiment, the power component 2 also includes an integrated fixing frame 24, an electromagnetic induction charging coil 25 and a cyclically chargeable and dischargeable battery. The cyclically chargeable and dischargeable battery is mounted on one side of the integrated fixing frame 24 and is used to power the vibration motor 21 and the circuit board 22; the electromagnetic induction charging coil 25 is wound and fixed on the integrated fixing frame 24, and the electromagnetic induction charging coil 25 is electrically connected to the circuit board 22 and is used to perform wireless induction charging on the cyclically chargeable and dischargeable battery.

[0055] In this embodiment, the integrated mounting bracket 24 is provided with a battery slot, fixing posts corresponding to fixing holes on the circuit board 22, a socket that matches the fixed plug on the vibration motor 21, and a coil frame for winding the electromagnetic induction charging coil 25. It integrates multiple functions into one, serving as a fixing device for the electromagnetic induction charging coil 25, a mounting and fixing device for the power source (i.e., a battery that can be cyclically charged and discharged), and a bracket and fixing device for the circuit board 22 and vibration motor 21. The vibration motor 21, circuit board 22, battery, and electromagnetic induction charging coil 25 of the electric toothbrush 100 are respectively fixed to the integrated mounting bracket 24 via detachable structures such as sockets and clips, forming the core power component of the electric toothbrush 100. This part of the assembly also does not require any screws, simplifying the installation process and facilitating disassembly and maintenance.

[0056] In this embodiment, the electromagnetic induction charging coil 25 is preferably wound with 42 turns of enameled wire and fixed on the coil frame of the integrated fixing frame 24 . The coil frame and the vibration motor 21 are respectively arranged at two ends of the integrated fixing frame 24 .

[0057] In this embodiment, the above-mentioned cyclically chargeable and dischargeable battery is preferably a large-capacity extended-length 14650 model ternary lithium battery, which has a larger capacity, longer battery life, and longer service life than the 14500 battery most commonly used in electric toothbrushes on the market.

[0058] In this embodiment, the vibration motor 21 is a sonic vibration motor that is detachably mounted on one end of the integrated fixing frame 24. The sonic vibration motor is a high-frequency sonic vibration motor with a wide range of vibration frequencies between 170 Hz and 600 Hz, capable of achieving a vibration frequency range of 10,000 to 38,000 times per minute, and an output power range of 1.5 watts to 2.5 watts at a rated voltage of 3.7 volts. Different vibration modes of the electric toothbrush 100 are achieved according to the different modes of current output by the circuit board 22.

[0059] In this embodiment, a limiting frame structure is provided on the inner wall of the sealing cover 12, and the limiting frame structure is used to be clamped on the outer wall of the acoustic vibration motor to prevent the acoustic vibration motor from rotating relative to the lower housing 11. The above-mentioned limiting frame structure is preferably a plate rib structure, and a plurality of plate rib structures are spaced apart and distributed on the inner wall of the sealing cover 12.

[0060] In this embodiment, the circuit board 22 is preferably an integrated chip circuit board that integrates the switch, mode display light, mode switching, charging display, and power supply display light of the electric toothbrush. The integrated chip circuit board is arranged on the other side of the integrated fixing frame 24. The integrated chip circuit board has the function of adjusting the vibration frequency of the vibration motor 21. Different vibration frequencies of the vibration motor 21 correspond to different vibration modes of the brush head 3. The above-mentioned "mode switching" refers to adjusting the vibration frequency of the vibration motor 21 to the corresponding vibration mode. The integrated chip circuit board is equipped with mode display lights corresponding to different vibration modes of the brush head 3, that is, each vibration mode of the brush head 3 corresponds to a mode display light. Correspondingly, the integrated chip circuit board is also equipped with a charging display light and a power supply display light. The charging display light and the power supply display light can be a shared light or two lights set separately. The switch control and vibration mode switching functions of the above-mentioned circuit board 22 both adopt touch mode. For example, double-clicking the button area (i.e., the touch-sensitive operation interface 111) and touching the touch-sensitive button 23 can trigger the switch function of the electric toothbrush 100 (double-clicking to turn on, double-clicking again to turn off). Within the first 5 seconds of the power-on state, long touching the button area (i.e., the touch-sensitive operation interface 111) can switch the vibration mode of the electric toothbrush. After 5 seconds of power-on, single-clicking or long touching the button area (i.e., the touch-sensitive operation interface 111) will not trigger the shutdown and mode switching functions. This mode setting avoids the shutdown and brushing mode changes caused by accidentally touching the button during the use of the electric toothbrush 100. The touch start mode of the above-mentioned touch-sensitive operation interface 111 combined with the touch-sensitive button 23 further avoids the shell gap required by traditional button keys, reduces the waterproof sealing link of the lower shell 11, and achieves higher waterproof requirements. The above-mentioned touch start mode adopts the existing capacitive touch button principle, which will not be repeated here.

[0061] In this embodiment, a light shield 26 is also provided on the circuit board 22. The light shield 26 covers the surface of the circuit board 22 and defines a mode light hole 261 for revealing a mode indicator light and a battery level indicator hole 262 for revealing a power level indicator light. The light shield 26 is preferably injection-molded from environmentally friendly TPE material and is black. Its purpose is to reduce the divergence of the display light, ensuring that the display light for each mode is clearly and independently displayed.

[0062] In this embodiment, the electric toothbrush 100 has five different vibration modes for the brush head 3, and five corresponding mode indicator lights are provided. The corresponding mode indicator light illuminates when the brush head 3 vibrates in a different vibration mode, while the remaining mode indicator lights remain off. The five mode indicator lights are spaced apart along the axial direction of the lower housing 11.

[0063] In this embodiment, the outer wall of the lower shell 11 is provided with mode annotations 5 corresponding to the five mode display lights for easy identification by the user. The mode annotations 5 are in Chinese or English. In actual operation, the five mode annotations 5 can be "Deep clean", "Clean", "White", "Gum Health" and "Sensitive". The specific vibration frequency corresponding to each mode can be adaptively adjusted according to actual production needs and user needs. The Chinese explanations corresponding to the above-mentioned "Deep clean", "Clean", "White", "Gum Health" and "Sensitive" can be "deep clean", "clean", "whitening", "gum health" and "gum sensitive" respectively.

[0064] In this embodiment, in addition to the above-mentioned mode annotation 5, a brand logo and other contents may be printed on the outer surface of the lower shell 11 to facilitate user identification.

[0065] In this embodiment, waterproof structures such as a fixed collar 6 and a waterproof rubber sleeve are also arranged between the brush head 3 and the output shaft 211. The brush head 3, the fixed collar 6, the above-mentioned waterproof rubber sleeve and the waterproof sealing ring 4 are all customized accessories and waterproof sealing accessories matched with the electric toothbrush 100 of this embodiment.

[0066] The electric toothbrush proposed in this embodiment is essentially a high-performance, waterproof, touch-sensitive electric toothbrush with five vibration modes, touch-sensitive switching between different brushing modes, and wireless induction charging, making it convenient and quick to use. The housing molding technology, snap-on sealing structure, and touch-sensitive buttons of this electric toothbrush achieve higher waterproof requirements and extend the lifespan of the electric toothbrush. The lower housing utilizes an inner surface spray coating process, allowing for flexible color combinations and durable, non-fading wear. This not only prevents scratches and wear on the surface coating, but also ensures that the color of the toothbrush body remains bright and new for a long time.

[0067] The following is a detailed description of the use of the electric toothbrush 100 of this embodiment.

[0068] After installing the waterproof sealing ring, the fixed collar 6 and the waterproof rubber sleeve on the output shaft 211 of the vibration motor 21, the power component 2 is installed as a whole into the lower shell 11, and then the sealing cover 12 is covered (the sealing cover 12 has a waterproof sealing ring 4). The outer wall of the vibration motor 21 is prevented from rotating and swinging by the limiting frame structure on the inner wall of the sealing cover 12. The vibration motor 21 and the integrated fixing frame 24 will not rotate or swing. The sealing cover 12 is tightly connected to the lower shell 11 through the concave and convex slot structure. Based on this, the handle part of the electric toothbrush 100 is assembled; finally, the brush head 3 is inserted into the output shaft 211 and enters the ready-to-use state. When in use, double-click the touch-sensitive operation interface 111 on the lower shell 11 to turn on the electric toothbrush 100. Long touch the touch-sensitive operation interface 111 within the first 5 seconds to switch the vibration mode of the electric toothbrush 100. The lower shell 11 can display the light of the mode display light and print the corresponding mode annotation 5. After the mode is selected, you can start brushing your teeth. During the brushing process, the electric toothbrush 100 is equipped with a 30-second zone change reminder function, that is, it pauses every 30 seconds to remind you to change the brushing area, and automatically shuts down after 2 minutes. The next time you turn it on, it has a memory mode, that is, the same vibration mode used for brushing last time. The handle shell 1, core power components, touch switch and mode switching function, use of waterproof rubber sleeve and waterproof sealing ring, screwless installation structural assembly design, etc. of the electric toothbrush 100 of this embodiment are all interdependent and matched. The interlocking of various components together constitute the waterproof barrier of the entire electric toothbrush 100. In addition to ensuring the efficient waterproof performance of the electric toothbrush 100 and effectively extending the service life of the electric toothbrush 100, the electric toothbrush 100 has complete functions. It has many advantages such as strong power, diverse brushing modes, aesthetic appearance and comfortable feel.
