[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When the magnetic block fixing sleeve is installed on the outside of the brush head, the magnetic control structure automatically opens the drying channel. When not drying, the compression spring pushes the second drying channel of the sealing plate to be misaligned with the first drying channel, preventing water from entering the air outlet box during brushing. After the air enters through the air inlet filter, it first intercepts large-diameter water droplets through the tortuous air channel formed by the misaligned partition, then uses the surface tension of the microporous membrane to block liquid water, and finally the centrifugal force generated by the impeller rotation separates the fine water mist. This triple treatment ensures that the blown dry air efficiently penetrates the bristles. This mechanism not only accelerates the evaporation of moisture from the bristles and reduces the moisture environment, but also... This design prevents bacterial growth in the brush head and keeps it hygienic, avoiding damage to the bristles that can occur with traditional heat drying. The integrated design balances water resistance and airflow, allowing users to quickly dry the brush head after use simply by attaching the magnetic retainer. This effectively extends the lifespan of the electric toothbrush and improves hygiene and convenience for daily use. It solves the problem of damp brush heads that can easily breed bacteria and mold when users are traveling or on business trips, increasing the risk of oral infections and producing odors, thus affecting the user experience.

[0015] 2. This invention utilizes an intelligent sensing mechanism that couples touch sensing with human body capacitance to automatically activate the vibration function when the handle is gripped and immediately stop operation when the hand is removed. This completely solves the problem of traditional electric toothbrushes requiring manual shutdown. The automatic stop of vibration when the toothbrush is placed down significantly reduces toothpaste splatter, making it particularly suitable for scenarios with high cleaning needs, such as bathroom sinks. Addressing the issue of unstable grip for children or first-time users, the automatic stop function prevents accidental operation, enhancing safety and convenience. For situations where there is moisture, water droplets, or water flow on the surface of the electric toothbrush or on the hands, the touch-sensitive switch ensures not only sensitive touch button response but also prevents accidental triggering.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1:

[0026] An oral hygiene device includes an electric toothbrush handle 1, a toothbrush head mechanism 2 movably mounted on the top of the handle 1, bristles 8 fixedly mounted on one side of the upper end of the toothbrush head mechanism 2, a connecting seat 5 below the toothbrush head mechanism 2, an air collection box 6 above the connecting seat 5, a brush head end 7 fixedly mounted above the air collection box 6, an impeller shaft 14 rotatably mounted inside the air collection box 6, an impeller 13 fixedly fitted outside the impeller shaft 14, and an air inlet filter 15 at the middle of the upper end of the air collection box 6 communicating with the interior of the brush head end 7. An air collecting pipe 17 is fixedly installed inside the lower end of the brush head end 7. An air supply pipe 18 is sealed and installed above the air collecting pipe 17. An air outlet box 19 is fixedly installed inside the upper end of the brush head end 7. The air outlet box 19 is sealed and connected to the air supply pipe 18. A sealing plate 31 is slidably installed inside the air outlet box 19. Five first air drying channels 32 are equidistantly opened at the upper end of the brush head end 7. Five second air drying channels 35 are equidistantly opened inside the sealing plate 31. The second air drying channels 35 are correspondingly arranged with the first air drying channels 32. A magnetic block fixing sleeve 36 is movably fitted on the outside of the toothbrush head mechanism 2.

[0027] Through the integrated design of components such as the electric toothbrush handle 1, toothbrush head mechanism 2, bristles 8, air collection box 6, and brush head end 7, a complete air-drying channel is constructed: when the impeller 13 rotates, air is drawn in through the air inlet filter plate 15 and delivered to the air outlet box 19 through the air collection pipe 17 and the air delivery pipe 18. With the magnetic alignment of the sealing plate 31 with the first air-drying channel 32 and the second air-drying channel 35, the bristles 8 can be quickly and directionally dried after the magnetic block fixing sleeve 36 is installed, realizing an integrated and compact layout of cleaning and drying functions.

[0028] Please see Figure 1 The electric toothbrush handle 1 has a control button 3 installed on the side of its upper end.

[0029] The control buttons can be used to activate the vibration motor to enable the toothbrush's vibration cleaning function and the fan motor to activate the drying function. The combination of the two takes into account both intelligent sensing and active control needs, improving the ease of operation in different usage scenarios.

[0030] Please see Figure 2-3A water-blocking seat 20 is provided on the upper side of the outer end of the connecting seat 5. The height of the water-blocking seat 20 gradually increases from the outside to the inside. The lower end of the air collecting box 6 is fixedly connected to the water-blocking seat 20. An air inlet filter 12 is fixedly installed on the outside of the lower end of the air collecting box 6. A first water-blocking plate 21 is fixedly installed inside the outer end of the air collecting box 6. A second water-blocking plate 22 is fixedly installed on the inside of the first water-blocking plate 21. The lower ends of the first water-blocking plate 21 and the lower ends of the second water-blocking plate 22 are in contact with the upper surface of the water-blocking seat 20. An upper through groove 27 is provided on the upper end of the first water-blocking plate 21. The lower end of the second water-blocking plate 22 is provided with a lower through groove 29. The front and rear ends of the upper through groove 27 are provided with a first water-blocking membrane 28. The front and rear ends of the lower through groove 29 are provided with a second water-blocking membrane 30. Three first partitions 25 are installed at equal intervals on the inner wall of the outer side of the air collecting box 6. The outer wall of the first water-blocking plate 21 is provided with multiple second partitions 26. The first partitions 25 and the second partitions 26 are staggered. The end of the first partition 25 near the second partition 26 is inclined downwards, and the end of the second partition 26 near the first partition 25 is inclined downwards.

[0031] The connecting seat 5, the air collecting box 6, the water blocking seat 20, the first water blocking plate 21 and the second water blocking plate 22 constitute a multi-stage water blocking system. The slope design of the water blocking seat 20 guides water to gather downwards due to gravity, thereby preventing it from entering the air collecting box. The first partition 25 and the second partition 26 are staggered to form a tortuous air channel to intercept large-diameter water vapor. The first water blocking membrane 28 and the second water blocking membrane 30 block liquid water through surface tension. Together with the air inlet filter 12, they filter impurities to ensure that the air entering the drying channel is dry and clean, and to prevent bacteria from growing on the brush bristles 8 due to the humid environment.

[0032] Please see Figure 2-5 A vibration motor shaft 10 is installed at the middle position of the upper end of the electric toothbrush handle 1. A vibration motor bushing 11 is fixedly installed at the middle position of the lower end of the connecting seat 5. The vibration motor shaft 10 is in contact with the inner wall of the vibration motor bushing 11. A connecting sleeve 9 is fixedly installed at the outer end of the electric toothbrush handle 1. The outer end of the lower side of the connecting seat 5 is snapped into the connecting sleeve 9. A fan motor mounting seat 23 is fixedly installed on one side of the upper end of the electric toothbrush handle 1. A fan motor 24 is fixedly installed inside the upper end of the fan motor mounting seat 23. An active magnetic block 40 is fixedly installed at the output end of the fan motor 24. An active gear shaft 43 is rotatably installed on one side of the impeller shaft 14. A driven magnetic block 39 is fixedly mounted on the lower end of the active gear shaft 43. The driven magnetic block 39 and the active magnetic block 40 are magnetically connected. An active gear 41 is fixedly mounted on the middle position of the active gear shaft 43. A driven gear 42 is fixedly mounted on the lower end of the impeller shaft 14. The active gear 41 and the driven gear 42 are meshed and connected.

[0033] The vibration motor shaft 10 and the vibration motor bushing 11 work together to transmit vibration during cleaning. The snap-fit ​​structure between the connecting sleeve 9 and the connecting seat 5 ensures easy disassembly and assembly. The fan motor 24 drives the impeller 13 to rotate through the magnetic attraction transmission of the active magnetic block 40 and the driven magnetic block 39, and the meshing of the active gear 41 and the driven gear 42. The non-contact magnetic drive design prevents water vapor from entering the motor, while ensuring the stable operation of the impeller 13 to generate centrifugal force to separate fine water mist, thus ensuring the high efficiency of the drying airflow.

[0034] Please see Figure 5-7 An iron block 38 is fixedly installed at the middle position on one side of the sealing plate 31. A magnet block 37 is fixedly installed inside one side of the magnet block fixing sleeve 36. The magnet block 37 corresponds to the iron block 38 and is magnetically connected. A compression spring sliding sleeve 45 is provided between the upper and lower ends of one end of the sealing plate 31 and the inner wall of one side of the air outlet box 19. The compression spring sliding sleeve 45 is divided into two slidably connected sleeves. A compression spring 46 is provided inside the compression spring sliding sleeve 45. The two ends of the compression spring 46 are respectively attached to one end of the sealing plate 31 and the inner wall of one side of the air outlet box 19. A sealing plate groove 33 is fixedly provided on the upper and lower inner walls of the air outlet box 19. A sealing plate positioning block 34 is symmetrically provided on both sides of the upper and lower ends of the air outlet box 19. The sealing plate groove 33 and the sealing plate positioning block 34 are slidably connected.

[0035] The sealing plate 31 is guided to slide through the sealing plate groove 33 and the sealing plate positioning block 34. The compression spring 46 and the compression spring sliding sleeve 45 provide the reset force. The magnetic attraction between the magnet block 37 and the iron block 38 drives the sealing plate 31 to open and close. When the magnet block fixing sleeve 36 is installed, the magnetic attraction drives the sealing plate 31 to align the first air drying channel 32 and the second air drying channel 35, opening the air drying channel. After removal, the spring resets and closes the channel, which not only prevents dust from entering the brush head, but also avoids airflow leakage when not in use, realizing intelligent sealing control of the air drying channel.

[0036] Working principle: After using the toothbrush, the magnet fixing sleeve 36 is fitted onto the outside of the brush head end 7 through the sliding groove. At this time, the magnet 37 of the magnet fixing sleeve 36 attracts the iron block 38 on one side of the sealing plate 31. The attraction force is greater than the elastic force of the compression spring 46, thereby driving the sealing plate 31 to slide towards the magnet 37 as limited by the sealing plate sliding groove 33 and the sealing plate positioning block 34. At the same time, due to the limitation of the width of the sealing plate sliding groove 33, the first air drying groove 32 and the second air drying groove 35 are aligned after the sealing plate 31 slides. The electric toothbrush is placed upright. At this time, the control button 3 is pressed to turn on the fan motor 24. The fan motor 24 drives the drive gear shaft 43 to rotate synchronously through the magnetic attraction of the active magnet 40 and the driven magnet 39. The drive gear shaft 43 drives the drive gear 41 to rotate. The drive gear 41 drives the driven gear 42 to rotate through meshing connection. The driven gear 42 drives the driven gear 42 to rotate. The impeller shaft 14 rotates, causing the impeller 13 to rotate. The rotating impeller generates negative pressure, drawing air in through the inlet filter 12. The moisture drawn in by the inlet filter 12 is blocked by the first baffle 25 and the second baffle 26 in sequence. The moisture in the air will accumulate at the contact surface of the first baffle 25 and the second baffle 26. The air flows with the first water-blocking plate 21 into the upper channel 27, passes through the two first water-blocking membranes 28, and the moisture in the air is isolated on one side of the first water-blocking membrane 28. The air is guided by the second water-blocking plate 22 and passes through the two second water-blocking membranes 30, where the moisture is blocked again. The air enters the interior of the air collecting box 6, passes through the inlet filter 15 with the blowing of the impeller 13, and enters the interior of the air outlet box 19 with the air collecting pipe 17 and the air delivery pipe 18. It is then blown out by the first drying channel 32 and the second drying channel 35, thereby promoting the rapid drying of the bristles 8.

[0037] Example 2:

[0038] An oral hygiene device includes an electric toothbrush handle 1, a toothbrush head mechanism 2 movably mounted on the top of the handle 1, bristles 8 fixedly mounted on one side of the upper end of the toothbrush head mechanism 2, a connecting seat 5 located below the toothbrush head mechanism 2, an air collection box 6 located above the connecting seat 5, and a brush head end 7 fixedly mounted above the air collection box 6. A control button 3 is mounted on the upper side of the electric toothbrush handle 1, and a touch-sensitive switch 4 is mounted on the lower side of the electric toothbrush handle 1.

[0039] The electric toothbrush handle 1 and toothbrush head mechanism 2 are connected by a movable connection. With the hierarchical installation of the connecting seat 5, air collection box 6 and brush head end 7, an integrated carrier for cleaning and drying functions is formed. The bristles 8 are installed on the outside of the brush head end 7. The impeller assembly built into the air collection box 6 can guide airflow to the bristles 8 through the air inlet channel. The supporting structure of the connecting seat 5 not only ensures the vibration transmission stability of the toothbrush head mechanism 2, but also provides an installation base for the air collection box 6 to realize the cleaning function. The control button 3 and the touch sensor switch 4 form a dual control system. The touch sensor switch 4 realizes automatic control of the electric toothbrush based on human capacitive sensing to start when gripped and stop when removed, avoiding toothpaste splashing when placed. The control button can also be used to manually turn on the fan motor 24 to start the drying function. The combination of the two takes into account the needs of intelligent sensing and active control, and improves the convenience of operation in different usage scenarios.

[0040] Please see Figure 2 A vibration motor shaft 10 is installed at the middle position of the upper end of the electric toothbrush handle 1, and a vibration motor bushing 11 is fixedly installed at the middle position of the lower end of the connecting seat 5. The vibration motor shaft 10 is in contact with the inner wall of the vibration motor bushing 11, and a connecting sleeve 9 is fixedly installed at the outer end of the electric toothbrush handle 1. The outer end of the lower side of the connecting seat 5 is snapped into connection with the connecting sleeve 9.

[0041] The precise fit between the vibration motor shaft 10 and the vibration motor bushing 11 ensures that the vibration power inside the electric toothbrush handle 1 is efficiently transmitted to the toothbrush head mechanism 2, realizing the high-frequency vibration function of the toothbrush; the snap-fit ​​structure between the connecting sleeve 9 and the connecting seat 5 ensures the stability of vibration transmission while supporting the quick disassembly and assembly of the toothbrush head mechanism 2, making it convenient for users to replace the brush head or maintain internal components, thus balancing functionality and ease of use.

[0042] Working principle: When using the electric toothbrush, gripping the handle 1 activates the touch sensor switch 4 on the handle 1, creating a coupling capacitor between the human body and the electrode, causing a change in the total capacitance value. The circuit detects this change and triggers the switch. Pressing the control button 3 then activates the vibration motor inside the handle 1. The vibration motor drives the motor shaft 10 to vibrate, transmitting the vibration to the toothbrush head mechanism 2 via the motor shaft sleeve 11, thus transmitting vibration to the brush head end 7, enabling the use of the electric toothbrush. When putting down the electric toothbrush, the hand leaves the touch sensor switch 4. When the hand is detected leaving the brush head, the power to the motor shaft 10 is disconnected, automatically pausing operation and preventing toothpaste splattering when putting down the toothbrush. This design is suitable for children or first-time users, reducing operational errors.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
