Description

Electric full-tooth cleaning device This invention relates to a dental cleaning device, and more particularly to an electric full-tooth cleaning device. Technological advancements make life more convenient, and electric toothbrushes are one such technological product. They shorten brushing time, effectively clean teeth, and provide users with a more convenient and automated teeth cleaning tool. Electric toothbrushes on the market are generally divided into long-handled electric toothbrushes and tray-type electric toothbrushes. Please refer to Figure 1 for an illustration of patent TW 201338761, an automatic teeth cleaning device 1. This automatic teeth cleaning device 1 is a toothbrush tray type electric toothbrush, which includes a toothbrush tray structure 11, a water injection module 12, a water extraction module 13, an assembly structure 14, a power transmission module 15, a sonic module 16, and a bristle module (not shown in the figure). The water injection module 12 can inject water into the toothbrush tray structure 11 and drive the bristle module to rotate. The toothbrush tray structure 11 has a plurality of holes 111 to allow water to flow out of the toothbrush tray structure 11. The sonic module 16 can vibrate the water in the toothbrush tray structure 11 and the bristle module. The water extraction module 13 extracts the water from the toothbrush tray structure 11. The power transmission module 15 can supply power to the sonic module 16. The assembly structure 14 can assemble and fix the toothbrush tray structure 11. Although prior art has revealed a tray-type electric toothbrush, it still has the following drawbacks in actual use: 1. Dangerous Use and Chinning: The conventional water injection module not only injects water into the dental tray structure, but also drives the brush module to rotate or vibrate. Therefore, the water injection module must continuously inject water, and the intensity of the water injection must be sufficient to drive the brush module to rotate. This causes the user's mouth to easily fill with a large amount of water. However, some patients who are not conscious or have difficulty controlling their muscles have difficulty controlling their throat muscles. This causes the injected water to stimulate the swallowing reflex in the throat, which not only easily leads to choking, but also poses a risk of choking and suffocation. 2. Ineffective Tooth Cleaning: As mentioned above, the water injection hole in the conventional toothbrush holder structure is located on the bottom surface, and the water injected only exists on the occlusal surface of the teeth. The water injection is not uniform. When too much water is injected, it is easy to cause choking. When too little water is injected, it is difficult to drive the bristle module to rotate. The bristles on the sides of the teeth are prone to dry brushing. This not only fails to remove dental plaque, but also reduces the area cleaned by the bristles. As a result, the existing toothbrush holder type electric toothbrush cannot effectively clean teeth. 3. Prone to limescale buildup and bacterial growth: In order for the braces to dispense water, a hidden water channel is usually installed inside the braces to deliver water to the water inlet. However, the water channel inside the braces is generally difficult to clean. Long-term exposure to moisture can easily lead to limescale buildup, and the damp environment can also easily trap dirt and grime. Therefore, braces generally have the problem of limescale buildup and bacterial growth. In 2022, pneumonia ranked fourth among the top ten causes of death in Taiwan. Pneumonia is a general term for inflammation of the alveoli in the lungs, causing various symptoms. Aspiration pneumonia, caused by foreign objects or fluids carrying bacteria entering the lungs, accounts for a large proportion. According to medical literature and doctors, as people age, the larynx lowers in position. When ingesting fast-flowing liquids such as water, the larynx takes longer to rise, and the airway may not close in time, causing choking. In addition to aging, conditions such as weak tongue, relaxed throat and esophageal muscles, cognitive decline, or stroke can all lead to difficulty swallowing. Patients who have recently had their nasogastric tube removed and are unable to adapt to the rapid flow of water through their throats are most prone to choking. Therefore, how to avoid choking when using a tray-type electric toothbrush so that patients and the elderly with impaired consciousness or difficulty in muscle control can use it, and how to ensure that the water is evenly distributed in the tray structure to effectively moisten the bristles to clean the tooth surface, and how to provide users with easy access to clean the internal water channels, are goals that relevant technicians urgently need to work on. In view of this, the object of the present invention is to provide an electric full tooth cleaning device, which includes a base unit, a liquid control unit, and a vibration control unit.

After the upper assembly and the lower assembly are separated, the internal flow channel can be exposed to the outside through the upper and lower grooves, which can provide cleaning for the user and prevent the formation of scale and bacteria in the occlusal base. The features and technical content of the related patent applications of this invention will be clearly presented in the following detailed description of two embodiments with reference to the accompanying drawings. It should be noted before the detailed description that similar elements are represented by the same reference numerals. Please refer to Figures 2, 3, and 4 for a first embodiment of an electric full-tooth cleaning device of the present invention.

The operating unit 6 includes a protective housing 61, an operating interface 62 disposed on the protective housing 61, a second assembly structure 63 disposed on the protective housing 61 and detachably assembled with the first assembly structure 34, and a transmission line group 64 disposed between the protective housing 61 and the second assembly structure 63. Please refer to Figures 2, 3, and 5. The occlusal base 31 has a central transverse wall 311, two upper side baffles 312 that are perpendicularly connected to the central transverse wall 311, and two lower side baffles 313 that are connected to the central transverse wall 311. The central transverse wall 311 is located in the middle of the occlusal base 31. The central transverse wall 311, the two upper side baffles 312, and the two lower side baffles 313 cooperate to define the cross-section of the occlusal base 31, which is generally H-shaped. The occlusal base 31 has a curved overall structure when viewed from above, which is used to match the curvature of human teeth. The upper teeth can be placed into the upper concave part of the H shape, and the lower teeth can be placed into the lower concave part of the H shape. The occlusal surface of the upper teeth contacts the upper surface of the middle transverse wall 311, and the side surface of the upper teeth contacts the inner surface of the two upper side walls 312. The occlusal surface of the lower teeth contacts the lower surface of the middle transverse wall 311, and the side surface of the lower teeth contacts the inner surface of the two lower side walls 313. The flow channel structure 33 is provided with a plurality of upper openings 331 and a plurality of lower openings 332 in the upper and lower halves of the H-shape, respectively. In the first embodiment, the flow channel structure 33 has a plurality of upper openings 331 disposed on the inner surface of the upper baffle wall 312, a plurality of lower openings 332 disposed on the inner surface of the lower baffle wall 313, and a plurality of central openings 333 disposed on the upper and lower surfaces of the middle transverse wall 311. The plurality of upper openings 331, the plurality of lower openings 332, and the plurality of central openings 333 are respectively located on the occlusal surfaces and inner and outer walls (buccal side) of the anterior teeth, canines, small molars, and large molars. They are cavities for injecting or drawing liquids. A group of cavities is provided for two to three teeth. In actual implementation, the positions of the plurality of upper openings 331, the plurality of lower openings 332, and the plurality of central openings 333 can be adjusted according to the overall size of the occlusal base 31 or the oral structure of the user, and should not be limited thereto. The height of the plurality of upper openings 331 is approximately at the middle height of the upper teeth, and the height of the plurality of lower openings 332 is approximately at the middle height of the lower teeth. In the first embodiment, the plurality of upper openings 331 are located at half the height of the two upper baffles 312, and the plurality of lower openings 332 are located at half the height of the two lower baffles 313, but are not limited thereto. The flow channel structure 33 further includes a main flow channel 334 disposed inside the middle transverse wall 311 and communicating with the plurality of central openings 333, a plurality of side flow channels 335 disposed inside the middle transverse wall 311 and communicating with the main flow channel 334, a plurality of upper flow channels 336 disposed inside the two upper side baffles 312, and a plurality of lower flow channels 337 disposed inside the two lower side baffles 313. The main channel 334 connects to the first combined structure 34 and is connected to the injection module 41 through the first combined structure 34. The plurality of upper channels 336 are respectively connected to the plurality of upper openings 331 and the plurality of side channels 335. The plurality of lower channels 337 are respectively connected to the plurality of lower openings 332 and the plurality of side channels 335. The injection module 41 can inject liquid into the channel structure 33 or suck liquid out of the channel structure 33. Please refer to Figure 6. The bristle module 32 has a plurality of bristle setting portions 321 disposed on the occlusal base 31 and a plurality of bristle assemblies 322 disposed on the plurality of bristle setting portions 321. The plurality of bristle setting portions 321 are recesses disposed on the occlusal base 31, and the plurality of bristle assemblies 322 are a plurality of bristles fixed in the plurality of bristle setting portions 321. A plurality of bristles can be fixed in each bristle setting portion 321. The bristles are the same as those disposed on existing toothbrushes, but are not limited thereto. The liquid control module 42 can control the injection module 41 to inject or extract liquid from the engagement base 31. When the injection module 41 injects liquid into the flow channel structure 33, the liquid sequentially enters the main flow channel 334, the plurality of side flow channels 335, the plurality of upper flow channels 336 and the plurality of lower flow channels 337, and then flows out from the plurality of upper openings 331, the plurality of lower openings 332 and the plurality of central openings 333 respectively. The liquid can enter the engagement base 31 from the plurality of upper openings 331, the plurality of lower openings 332 and the plurality of central openings 333 to moisten the plurality of bristle assemblies 322. Conversely, when the liquid injection module 41 draws liquid from the flow channel structure 33, it can generate suction from the plurality of upper openings 331, the plurality of lower openings 332, and the plurality of central openings 333 to draw out the liquid on the engagement base 31, and can also remove the liquid from the plurality of bristle assemblies 322. The vibration module 51 is connected to the engagement base 31. The vibration module 51 has a plurality of vibration structures 511 embedded in the engagement base 31. Each vibration structure 511 is a vibrating plate with internal vibration electronic circuitry and components. Unlike conventional motor vibration, the vibration module 51 uses the piezoelectric effect or magnetostrictive effect to generate vibration in the vibration structure 511. The drive module 54 provides electricity to drive the vibration module 51, which in turn causes the engagement base 31 to vibrate, thereby causing the plurality of bristle assemblies 322 to vibrate. In some embodiments, the vibration module 51 can also output sound waves or ultrasonic oscillations. The plurality of bristle setting parts 321 are respectively located on the upper and lower surfaces of the middle transverse wall 311, the inner sides of the two upper side baffles 312, and the inner sides of the two lower side baffles 313, and are arranged in two rows. The plurality of upper side openings 331, the plurality of lower side openings 332, and the plurality of central openings 333 are respectively located between the plurality of bristle setting parts 321 arranged in two rows. Because two rows of bristle modules 32 are arranged on both sides of the plurality of upper openings 331, the plurality of lower openings 332, and the plurality of central openings 333, when the liquid is injected from the plurality of upper openings 331, the plurality of lower openings 332, and the plurality of central openings 333, the liquid easily wets the bristle components 322 of the bristle module 32. When the liquid is drawn from the plurality of upper openings 331, the plurality of lower openings 332, and the plurality of central openings 333, the liquid on the bristle components 322 of the bristle module 32 is also easily drawn out. Please refer to Figures 5 and 7. The engagement base 31 further includes an upper assembly 314, a lower assembly 315 detachably assembled with the upper assembly 314, a groove 316 disposed on the upper assembly 314, and a groove 317 disposed on the lower assembly 315. The upper assembly 314 and the lower assembly 315 are combined to form the middle transverse wall 311, and the upper groove 316 and the lower groove 317 are combined to form the main flow channel 334 and the plurality of side flow channels 335. In this first embodiment, the first assembly structure 34 is connected to the lower assembly 315, the two upper side baffles 312 are connected to the upper assembly 314, and their cross-sections are U-shaped. The two lower side baffles 313 are connected to the lower assembly 315, and their cross-sections are inverted U-shaped. The assembly surface of the upper assembly 314 is provided with a plurality of combined recesses 318, and the assembly surface of the lower assembly 315 is provided with a plurality of combined protrusions 319. The plurality of combined recesses 318 are combined with the plurality of combined protrusions 319 so that the upper assembly 314 is fixed to the lower assembly 315. In actual implementation, other assembly structures can also be used between the upper assembly 314 and the lower assembly 315, and should not be limited thereto. When the upper assembly 314 is separated from the lower assembly 315, the upper groove 316 and the lower groove 317 are exposed, allowing the user to directly clean them. Alternatively, a brush similar to a toothbrush can be used to clean the upper flow channel 336 and the lower flow channel 337. When the upper assembly 314 and the lower assembly 315 are assembled, they are in close contact, preventing leakage of liquid from the main flow channel 334 and the plurality of side flow channels 335. Please refer to Figures 6 and 8. The structure of the plurality of bristle setting parts 321 is the recess of the engagement base 31 and the retaining ring in the recess. The plurality of retaining rings are connected to the opposite sides of the vibration structure 511, and the plurality of bristle assemblies 322 are fixed in the plurality of bristle setting parts 321. The vibration structure 511 is made of metal, which can effectively transmit vibration outward. The retaining rings of the plurality of bristle setting parts 321 are also made of metal, which can effectively receive the vibration transmitted by the vibration structure 511 and transmit the vibration to the plurality of bristle assemblies 322, so that the plurality of bristle assemblies 322 generate stronger vibration. It is worth noting that the engagement base 31 is made of elastic rubber. If the vibration output from the vibration module 51 is transmitted to the bristle module 32 through the engagement base 31, the engagement base 31 will weaken the vibration force and reduce the vibration of the bristle module 32. Therefore, the present invention fixes the plurality of bristle setting parts 321 to the side of the vibration structure 511, and the vibration generated by the vibration structure 511 is directly transmitted to the bristle module 32, so that the bristle module 32 can generate stronger vibration. Referring back to Figure 3, the operating unit 6 is a handheld main unit. When combined with the base unit 3, the base unit 3 can be placed in the oral cavity for full tooth cleaning. The liquid injection module 41 is disposed in the protective housing 61. The liquid injection module 41 has an injection component 411 connected to the flow channel structure 33, an elastic liquid storage container 412 connected to the injection component 411, a container cover 413 covering the elastic liquid storage container 412, a venting structure 414 disposed on the container cover 413, a liquid extraction component 415 connected to the flow channel structure 33, a sensing component 416 connected to the liquid extraction component 415, a waste liquid storage container 417 connected to the liquid extraction component 415, and an exhaust structure 418 disposed on the waste liquid storage container 417. The injection assembly 411 is a liquid pump used to inject liquid into the flow channel structure 33. The elastic liquid storage container 412 is a container made of elastic plastic. When the injection assembly 411 draws liquid from the elastic liquid storage container 412, the elastic liquid storage container 412 will be compressed to prevent air from being generated in the elastic liquid storage container 412. This prevents the injection assembly 411 from reducing its suction force and failing to draw liquid after drawing air. The elastic liquid storage container 412 will expand and return to its original shape after being replenished with liquid. The outer casing 413 of the container is a rigid shell. 413 covers the elastic liquid storage container 412, which can limit the liquid volume in the elastic liquid storage container 412. The main purpose is to protect the elastic liquid storage container 412 and prevent sharp objects from damaging it. The venting structure 414 is a vent provided on the outer cover 413 of the container, so that the elastic liquid storage container 412 can be compressed and expanded smoothly in the outer cover 413. The liquid stored in the elastic liquid storage container 412 is water. In actual implementation, the liquid used can also be mouthwash, medicine, toothpaste, etc., and should not be limited to this. In this first embodiment, the liquid extraction component 415 is connected to the waste liquid storage container 417 via the exhaust structure 418 and the flow channel structure 33. The liquid extraction component 415 is an air pump that can extract air from the waste liquid storage container 417. The exhaust structure 418 is located at the top of the waste liquid storage container 417. Due to gravity, the liquid will be stored at the bottom of the waste liquid storage container 417, and only air will pass through the exhaust structure 418. The liquid extraction component 415 extracts the liquid and air from the flow channel structure 33 through the waste liquid storage container 417, and the air and liquid in the engagement base 31 will be extracted from the flow channel structure 33. The sensing component 416 is a detector that measures the load level of the liquid extraction component 415, enabling the operation control component 621 to determine whether liquid has been extracted from the engagement base 31. In some embodiments, the sensing component 416 is a current detector; when the liquid extraction component 415 extracts air, the load is small and the operating current is low; when the liquid extraction component 415 extracts liquid, the load is large and the operating current is high. When the operating current of the liquid extraction component 415 decreases from high to low, the operation control component 621 can determine that liquid has been extracted from the engagement base 31. In some embodiments, the sensing component 416 is an infrared detector used to detect whether liquid is present in the air passing through the liquid extraction component 415. In some embodiments, the sensing component 416 is an electrical detector that detects the presence of liquid in the air passing through the liquid extraction component 415 using a resistive method. Referring to Figures 3 and 4, the transmission line assembly 64 has at least one conductive line 641 and at least one liquid conduit 642. The conductive line 641 connects the vibration module 51 and the drive module 54 respectively, so that the drive module 54 can supply power to the vibration module 51 to generate vibration. The first contact electrode 52 is a metal electrode disposed on the surface of the first combined structure 34, and the second contact electrode 53 is a metal electrode disposed on the surface of the second combined structure 63. In this first embodiment, the first combined structure 34 has a groove with a combined texture on its inner side, and the second combined structure 63 has a protrusion with a combined texture on its outer side. When the first combined structure 34 and the second combined structure 63 are combined, the first contact electrode 52 contacts the second contact electrode 53 to form an electrical connection so that the drive module 54 can supply power to the vibration module 51. In actual implementation, other combined structures can also be used for the first combined structure 34 and the second combined structure 63, and this should not be a limitation. The liquid conduit 642 connects the injection module 41 and the flow channel structure 33, so that the injection module 41 can communicate with the flow channel structure 33. The bottom surface of the first combined structure 34 is provided with the opening of the flow channel structure 33, and the convex surface of the second combined structure 63 is provided with the opening of the liquid conduit 642. When the first combined structure 34 and the second combined structure 63 are combined with each other, the opening of the flow channel structure 33 connects to the opening of the liquid conduit 642, and the combined structures around the opening abut against each other to form a sealing structure that prevents gas and liquid leakage. The liquid control unit 4 and the vibration control unit 5 are disposed in the protective housing 61. The operation interface 62 is connected to the liquid control module 42 and the vibration module 51 respectively. In the first embodiment, the operation interface 62 is a touch panel with a microcontroller, which can provide users with operation and display of work information, and has a program to control the liquid control unit 4 and the vibration control unit 5. In this first embodiment, the operation interface 62 has an operation control component 621 connected to the liquid control module 42, the sensing component 416, and the drive module 54, respectively. The operation control component 621 is an electronic circuit with a microcontroller. The operation control component 621 receives the detection data from the sensing component 416 and controls the injection, extraction, and vibration in turn. For example, when the electric full-tooth cleaning device starts operating, it first controls the injection component 411 to slowly inject liquid into the occlusal base 31. When the injected liquid reaches a set amount, the injection stops, and the vibration module 51 is controlled to generate vibration. When the vibration reaches a preset time, the extraction component 415 is controlled to drain the liquid from the occlusal base 31. After the operation control component 621 repeats the above process, the tooth cleaning operation is completed. The above operation procedure is performed in a cycle of water injection, rinsing, and extraction. In some embodiments, the operation control component 621 can also control the suction component 415 to suction the oral cavity through the occlusal base 31 at maximum power for suctioning operations, which can suction sputum from the oral cavity and throat. In this first embodiment, the liquid control module 42 is set to inject 3cc to 5cc of liquid from the injection module 41 every 5 seconds. In actual implementation, the liquid control module 42 can be adjusted according to the actual situation and should not be limited to this. When the amount of liquid injected into the occlusal base 31 is less than 3cc, there is not enough liquid on the bristle module 32, and it is still a dry brushing condition when vibrating, with limited tooth cleaning power. In particular, when there is no liquid adhering to the bristle assembly 322, the movement area of ​​the bristle assembly 322 on the tooth surface is limited when vibrating. If there is enough liquid adhering to the bristle assembly 322, the liquid will have a lubricating effect, allowing the bristle assembly 322 to move effectively on the tooth surface to remove dental plaque. However, when the amount of liquid in the occlusal base 31 exceeds 5cc, the liquid will leak out from the occlusal base 31. The electric full-tooth cleaning device of the present invention is suitable for users who lack self-awareness, have sarcopenia, or have slow muscle control. If the liquid leaks out from the occlusal base 31, it will stimulate the swallowing reflex in the throat, causing choking, coughing, or other situations. The liquid control module 42 controls the timing and amount of liquid injection, which can effectively assist the bristle assembly 322 in cleaning teeth and also prevent the liquid from leaking out from the occlusal base 31, thus preventing the user from choking or coughing. The present invention only requires a small amount of water to wet the bristles in the bristle assembly 322, and with the vibration of the vibration module 51, it can effectively clean the tooth surface. The cleaned liquid can also be quickly drawn out of the mouth, and the small amount of water can also prevent choking. Before actually using the electric full-tooth cleaning device of the present invention, liquid can be added to the elastic liquid storage container 412, toothpaste can be injected into the occlusal base 31, and after being placed in the user's mouth, the operation interface 62 can be operated to perform automatic tooth cleaning. Please refer to Figure 9, which shows a second embodiment of an electric full-tooth cleaning device of the present invention. The second embodiment is largely the same as the first embodiment, and the similarities will not be described in detail here. The difference is that the operating unit 6 is a control machine. In the second embodiment, the protective housing 61 can be placed on a table. In actual implementation, the protective housing 61 can also be set on a trolley, and should not be limited thereto. The operation interface 62 is a touch panel that can display the operation information of the liquid control unit 4 and the vibration control unit 5, and can also provide users with operation to input commands. The transmission line group 64 is a gas-liquid transmission line disposed between the protective housing 61 and the engagement base 31. The engagement base 31 is assembled on the second combined structure 63. The liquid injection module 41 and the drive module 54 are disposed in the protective housing 61. The liquid injection module 41 injects liquid into the engagement base 31 group through the liquid conduit 642 of the transmission line group 64, and also extracts liquid from the engagement base 31 group. The drive module 54 transmits electricity to the vibration module 51 through the conductive wire 641 of the transmission line group 64, so that the brush assembly 322 on the engagement base 31 vibrates. As can be seen from the above description, the electric full-tooth cleaning device of the present invention does indeed have the following effects: 1. Preventing users from choking: The liquid control module 42 controls the time and amount of liquid injection, and can inject liquid into the bite base 31 within the set time, which can prevent liquid from leaking out of the bite base 31 and will not irritate the user's throat. It is very suitable for users with impaired consciousness, sarcopenia or slow muscle reaction. II. Effective Teeth Cleaning: The liquid control module 42 is set to inject 3cc to 5cc of liquid into the injection module 41 every 5 seconds, so that the liquid wets and lubricates the bristle module 32, thereby expanding the vibration cleaning range of the bristle module 32. In addition, the liquid extraction component 415 effectively extracts the liquid from the occlusal base 31, which can remove the plaque that has been removed from the tooth surface. Then, clean liquid is injected and circulated to clean the user's teeth, which can effectively clean the teeth. 3. Easy to clean internally: The upper assembly 314 and the lower assembly 315 are combined to form the middle transverse wall 311, and the upper groove 316 and the lower groove 317 are combined to form the main flow channel 334 and the plurality of side flow channels 335. When the upper assembly 314 and the lower assembly 315 are separated, the upper groove 316 and the lower groove 317 are exposed to the outside, which makes it easy for users to clean the upper groove 316 and the lower groove 317. The upper flow channel 336 and the lower flow channel 337 can also be cleaned with a brush similar to a toothbrush. Therefore, the present invention can thoroughly clean the occlusal base 31. In summary, the liquid control module 42 can set the liquid injection time and volume of the injection module 41, ensuring that the liquid exists only in the occlusal base 31 and does not overflow, thus avoiding irritation to the throat and preventing choking. The liquid control module 42 cyclically controls the injection, vibration, and pumping of water by the vibration module 51, which can remove brushed plaque and inject clean liquid. In addition, the multiple upper openings 331 provided in the H-shaped occlusal base 31 further enhance the cleaning effect. The lower side opening 332 and the plurality of central openings 333 can evenly distribute water in the occlusal base 31, lubricating the bristle module 32 and expanding the area for vibration cleaning, thereby improving the cleaning power of the teeth. After the upper assembly 314 and the lower assembly 315 are separated, the internal flow channel can be exposed to the outside through the upper groove 316 and the lower groove 317, allowing the user to perform subsequent cleaning and avoid the formation of scale and bacteria in the occlusal base 31. Therefore, the purpose of the present invention can indeed be achieved. However, the above description is merely two embodiments of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the description of the invention shall still fall within the scope of the patent of the present invention. 1: Automatic dental cleaning device 11: Dental tray structure 111: Hole 12: Water injection module 13: Water extraction module 14: Combined structure 15: Power transmission module 16: Sonic module 3: Base unit 31: Occlusal base 311: Middle transverse wall 312: Upper side baffle 313: Lower side baffle 314: Upper assembly 315: Lower assembly 316: Upper groove 317: Lower groove 318: Combined recess 319: Combined protrusion 32: Brush module 321: Brush setting part 322: Brush assembly 33: Flow channel structure 331: Upper opening 332: Lower opening 333: Central opening 334: Main flow channel 335: Side flow channel 336: Upper flow channel 337: Downstream channel; 34: First combined structure; 4: Liquid control unit; 41: Liquid injection module; 411: Liquid injection assembly; 412: Elastic liquid storage container; 413: Container cover; 414: Ventilation structure; 415: Liquid extraction assembly; 416: Sensing assembly; 417: Waste liquid storage container; 418: Exhaust structure; 42: Liquid control module; 5: Vibration control unit; 51: Vibration module; 511: Vibration structure; 52: First contact electrode; 53: Second contact electrode; 54: Drive module; 6: Operating unit; 61: Protective housing; 62: Operating interface; 621: Operation control assembly; 63: Second combined structure; 64: Transmission line assembly; 641: Conductive wire; 642: Liquid conduit.
