Description

Technical Field

[0001] The invention relates to an oral cleaning tool, in particular to a visible dental floss used for cleaning gaps between teeth. Background Art

[0002] Due to aging, pathological reasons and other reasons, it is easy to cause gum atrophy and widen the gaps between teeth, which can easily lead to food residue. If not cleaned in time, on the one hand, it will produce bad breath, and on the other hand, it will easily lead to various dental diseases and oral diseases, especially periodontitis.

[0003] In response to this situation, various dental flosses are currently developed on the market for users to choose from. Although there are dental flosses of various structures and specifications on the market, existing products generally have the disadvantage of not being easy to observe the gaps between teeth. Especially when cleaning the gap between the third molar and the second molar, or the gap between the second molar and the first molar, or the gap between the first molar and the second premolar, since the gap to be cleaned is deep in the mouth, the light in the cleaning area is very dim and the gap to be cleaned cannot be seen clearly. The user can only operate by feeling, which can easily cause bleeding or damage to the gums. In order to overcome the shortcomings of the existing dental floss, it is necessary to develop a visual dental floss that can clearly observe the gaps between teeth under direct vision and observe the position of the dental floss and the cleaning effect in real time. Summary of the invention

[0004] The visual dental floss of the present invention is characterized by:

[0005] The visual dental floss 900 comprises a dental floss 100, an oral viewing device 200 and a connecting mechanism 300;

[0006] A. The dental floss 100 comprises a thread 11, a bracket 12, and a mounting seat 13; two ends of the thread 11 of the dental floss 100 are respectively fixed to the left arm 12-1 and the right arm 12-2 of the bracket 12, and the bracket 12 is arranged on the mounting seat 13;

[0007] B. The oral observation instrument 200 comprises a housing 21, a power system 22, a lighting system 23, an observation system 24, a circuit system 25 and a switch 26; the lighting system 23, the observation system 24, the circuit system 25 and the power system 22 are installed in the housing 21, and the switch 26 is installed on the housing 21; the lighting system 23, the observation system 24, the power system 22 and the switch 26 are connected together through the circuit system 25;

[0008] C. The dental floss 100 is installed on the oral viewing instrument 200 through the connecting mechanism 300.

[0009] In particular, the dental floss 100 can be detachably mounted on the oral viewing instrument 200 via the connecting mechanism 300 .

[0010] The line 11 of the dental floss 100 is within the field of view of the observation system 24 of the oral viewing instrument 200. In this way, the dental floss and the gaps between the teeth can be clearly seen, which facilitates the cleaning and treatment of the teeth under direct vision, and the cleaning effect of the teeth can be observed in real time.

[0011] The angle β between the line 11 of the dental floss 100 and the center line of the head 21-1 of the housing of the oral viewing instrument 200 is adjustable. In this way, the angle β can be adjusted according to the angle of the tooth gaps at different positions, so that the dental floss can enter the tooth gaps and clean the tooth gaps. The adjustable angle β can be achieved by adopting a passive mechanical structure such as a thread structure, a concave-convex card fitting structure, or a moderate interference fit structure; the angle β can also be adjusted by an active electric control method such as a motor transmission.

[0012] The connecting mechanism 300 is a detachable mechanical connecting mechanism; it can be an independent component, which can be arranged on the dental floss 100 or the oral viewing instrument 200; or a combined mechanical connecting mechanism formed by a part of the detachable mechanical connecting mechanism being arranged on the dental floss 100 and the other part being arranged on the oral viewing instrument 200. The connecting mechanism 300 can be a separate component, which is connected to the dental floss 100 and the oral viewing instrument 200 respectively, so as to connect the dental floss 100 and the oral viewing instrument 200 into a whole. The connecting mechanism 300 can also be manufactured into a whole with the dental floss 100 or the oral viewing instrument 200, and then connected with the oral viewing instrument 200 or the dental floss 100 to form a whole. However, no matter which connection method is used, the ultimate goal is to achieve a detachable connection between the dental floss 100 and the oral viewing instrument 200. Therefore, the connecting mechanism 300 only needs to be able to achieve a detachable mechanical connection with one of the dental floss 100 or the oral viewing instrument 200 to achieve a detachable connection between the dental floss 100 and the oral viewing instrument 200 .

[0013] The mechanical connection mechanism may be a concave-convex card-fit connection, or a slide connection, or a pin connection, or a key connection, or a threaded connection, or a screw connection, or a buckle connection, or a hook connection, or an interference fit connection, etc. Of course, those skilled in the art may choose other mechanical connection methods without departing from the protection scope of this application.

[0014] The mounting base 13 of the dental floss 100 is provided with a through hole 13-1, and the head 21-1 of the housing of the oral viewing instrument 200 can be inserted into the through hole 13-1, so that a detachable connection is formed between the dental floss 100 and the oral viewing instrument 200. When connecting, the connection can be formed by simply inserting the head 21-1 of the housing of the oral viewing instrument 200 into the through hole 13-1. When disassembling, the dental floss 100 can be removed from the oral viewing instrument 200 by slightly pulling out the oral viewing instrument 200 and the dental floss 100, which is very convenient to use.

[0015] The mounting seat 13 of the dental floss 100 is provided with a positioning groove 13-2; the connecting mechanism 300 is provided with a positioning hook 31 and a positioning convex step 32; the connecting mechanism 300 is installed on the oral viewing instrument 200 through the positioning convex step 32; the positioning hook 31 on the connecting mechanism 300 is embedded in the positioning groove 13-2 of the dental floss 100 to form a concave-convex card-fit connection, forming a detachable connection between the dental floss 100 and the oral viewing instrument 200. When disassembling, the dental floss 100 can be disassembled from the oral viewing instrument 200 by pressing the positioning hook 31. The concave-convex card-fit connection formed by the positioning hook 31 and the positioning groove 13-2 is safer and more reliable than the ordinary through-hole connection due to the effective positioning of the positioning hook 31.

[0016] The mounting seat 13 of the dental floss 100 is provided with a thread 13-3; the connecting mechanism 300 is a threaded connecting mechanism 33, which matches the thread 13-3 and is arranged on the head 21-1 of the housing of the oral viewing instrument 200; the thread 13-3 of the dental floss 100 can be mounted on the threaded connecting mechanism 33 by rotating the dental floss 100; the thread 13-3 of the dental floss 100 can be removed from the threaded connecting mechanism 33 by rotating the dental floss 100 in the opposite direction. At this time, the thread 13-3 on the mounting seat 13 can be set to a screw or a screw type, and the threaded connecting mechanism 33 of the connecting mechanism 300 is a corresponding nut; conversely, the thread 13-3 on the mounting seat 13 can be set to a nut type, and the threaded connecting mechanism 33 of the connecting mechanism 300 is a corresponding screw or a screw.

[0017] By rotating the thread 13-3 of the dental floss 100, the angle β between the thread 11 of the dental floss 100 and the center line of the head 21-1 of the housing of the oral viewing device 200 can be adjusted. In this way, the angle β can be adjusted in time according to the angle of the tooth gaps at different positions, so that the dental floss can enter the tooth gaps and clean the tooth gaps more conveniently.

[0018] The connecting mechanism 300 includes a slide bar 30, a positioning hook 31, a left positioning hook 31-1, a right positioning hook 31-2, a positioning convex step 32, and an anti-slip convex pattern 34; the positioning hook 31, the left positioning hook 31-1, and the right positioning hook 31-2 are arranged at the front end of the slide bar 30, the positioning hook 31 is in the middle, and the left positioning hook 31-1 and the right positioning hook 31-2 are arranged on both sides; the positioning convex step 32 is located in the middle of the slide bar 30; the anti-slip convex pattern 34 is arranged at the tail of the slide bar 30; the positioning convex step 32 is installed in the installation slot 21-2 of the housing 21 of the oral viewing instrument 200, The positioning convex step 21-3 of the housing 21 of the oral observation instrument 200 presses against the tail of the slide rod 30, so that the connecting mechanism 300 is detachably mounted and fixed on the housing 21 of the oral observation instrument 200; the head 21-1 of the housing 21 of the oral observation instrument 200 is embedded in the through hole 13-1 of the mounting seat of the dental floss 100, and the positioning hook 31 of the connecting mechanism 300 is embedded in the positioning groove 13-2 of the mounting seat, and the left positioning hook 31-1 and the right positioning hook 31-2 embrace the head 21-1 of the housing 21 of the oral observation instrument 200 from the left and right sides.

[0019] During installation, first, the positioning convex step 32 of the connection mechanism 300 is embedded in the mounting groove 21-2 of the housing 21 of the oral observation instrument 200, and the slide bar 30 of the connection mechanism 300 is slid forward until the positioning convex step 21-3 of the housing 21 of the oral observation instrument 200 bounces upward to support the tail of the slide bar 30. At this time, the left positioning hook 31-1 and the right positioning hook 31-2 embrace the head 21-1 of the housing 21 of the oral observation instrument 200 from both sides, and the connection mechanism 300 is installed and connected to the oral observation instrument 200. The design of the anti-slip convex pattern 34 can effectively prevent the slide bar 30 from slipping when sliding back and forth. The embracing effect of the left positioning hook 31-1 and the right positioning hook 31-2 and the concave-convex card fit between the positioning convex step 32 and the mounting groove 21-2 can effectively and firmly connect the oral observation instrument 200.

[0020] Then, the head 21 - 1 of the housing 21 of the oral viewing instrument 200 is embedded in the through hole 13 - 1 of the mounting seat of the dental floss 100 , and the dental floss 100 is pushed toward the connecting mechanism 300 . The positioning hook 31 of the connecting mechanism 300 can be embedded in the positioning groove 13 - 2 of the mounting seat 13 .

[0021] During disassembly, the top of the positioning hook 31 of the connecting mechanism 300 is pressed down, and the dental floss 100 is pulled outward to release the concave-convex engagement between the connecting mechanism 300 and the dental floss 100. When it is necessary to further remove the connecting mechanism 300 from the oral viewing instrument 200, the slide bar 30 is pulled back with force, the positioning convex step 21-3 of the oral viewing instrument 200 is pressed down, and the positioning convex step 32 of the connecting mechanism 300 is withdrawn from the mounting groove 21-2 of the embedded oral viewing instrument 200, until the connection between the connecting mechanism 300 and the oral viewing instrument 200 is completely released.

[0022] Since the positioning convex step 32 of the connecting mechanism 300 adopts an inverted T-shaped structure, when the T-shaped positioning convex step 32 is embedded in the mounting groove 21-2, the bottom of the inverted T-shaped structure can form a concave-convex card-fitting structure with the mounting groove 21-2, which can effectively limit the movement of the connecting mechanism 300 in the vertical direction, thereby preventing the connecting mechanism 300 and the oral viewing instrument 200 from detaching in the vertical direction during use. At the same time, the positioning convex step 21-3 of the oral observation instrument 200 is arranged at the rear end of the connecting mechanism 300. When the positioning convex step 21-3 of the oral observation instrument 200 is lifted upward, since the top position of the positioning convex step 21-3 is higher than the tail height of the connecting mechanism 300, the connecting mechanism 300 can be effectively prevented from retreating backward. Only when the connecting mechanism 300 is consciously retreated backward, the connecting mechanism 300 can be released from the oral observation instrument 200 after retreating along the guide surface of the positioning convex step 21-3, which can effectively prevent the dental floss 100 from accidentally loosening from the oral observation instrument 200 because the connecting mechanism 300 can easily retreat backward.

[0023] The observation system 24 is a camera system 24 - 1 , which includes a camera head 24 - 1 - 1 , a data processing and output system 24 - 1 - 2 , a circuit system 25 and a power supply system 22 .

[0024] The video data output by the data processing and output system 24-1-2 of the camera system 24-1 can be displayed on the display 24-1-3 through a wired connection or a wireless connection. The display 24-1-3 includes: a smart phone 24-1-31, a computer 24-1-32, a LCD display / TV 24-1-33, or a tablet computer 24-1-34.

[0025] The lighting system 6 is arranged around the camera 24 - 1 - 1.

[0026] The oral viewing instrument 200 adopts a waterproof design and includes a sealing device 21-4 for sealing the charging interface 25-1; the sealing device 21-4 includes a sealing ring 21-4-1, a pressing plate 21-4-2 and a slide plate 21-4-3; the sealing ring 21-4-1 is installed in the sealing groove 21-4-0 at the rear of the shell 21, the pressing plate 21-4- is pressed on the sealing ring 21-4-1, and the slide plate 21-4-3 is detachably pressed on the pressing plate 21-4-2; when the slide plate 21-4-3 slides into the rear of the shell 21 When the skateboard is in the skateboard positioning groove 21-4-4, the skateboard 21-4-3 presses the pressure plate 21-4-2, and the pressure plate 21-4-2 presses the sealing ring 21-4-1 to form a seal; when the skateboard 21-4-3 is pushed outward, the skateboard 21-4-3 is released from the skateboard positioning groove 21-4-4 at the rear of the shell 21, the skateboard 21-4-3 is tilted, the pressure of the pressure plate 21-4-2 is released, and it can be tilted upward to expose the sealed charging interface 25-1, the seal is released, and the oral observer 200 is charged.

[0027] Since the oral viewing instrument 200 is waterproof, when the oral viewing instrument 200 does not need to be charged, the slide plate 21-4-3 slides into the slide plate positioning groove 21-4-4, and the sealing ring 21-4-1 forms a seal. At this time, the oral viewing instrument 200 has good waterproof performance and can be easily washed and cleaned.

[0028] The visual dental floss 900 of the present invention comprises a dental floss 100, an oral observation instrument 200 and a connecting mechanism 300. The dental floss 100 and the oral observation instrument 200 are detachably connected together by the connecting mechanism 300. The connecting mechanism 300 can be fixedly connected to the dental floss 100 and the oral observation instrument 200 to form a whole, or it can be a detachable mechanical connecting mechanism. When the connecting mechanism 300 is a detachable mechanical connecting mechanism, it can be an independent component or it can be arranged on the dental floss 100 or the oral observation instrument 200. The line 11 of the dental floss 100 is within the field of view of the observation system 24 of the oral observation instrument 200. When using it, the gap between the dental floss and the teeth can be clearly seen, which is convenient for cleaning and treating the gap between the teeth under direct vision, and the cleaning effect of the gap between the teeth can be observed in real time.

[0073] The dental floss 100 is installed on the oral viewing instrument 200 through the connecting mechanism 300. In this embodiment, the dental floss 100 is detachably connected to the oral viewing instrument 200 by means of a concave-convex card fit through the connecting mechanism 300. A through hole 13-1 is provided on the mounting seat 13 of the dental floss 100, and the head 21-1 of the shell of the oral viewing instrument 200 can be embedded in the through hole 13-1. Figure 2 , Figure 2-1 and Figure 3 to Figure 3-2 .

[0074] The line 11 of the dental floss 100 is within the field of view of the observation system 24 of the oral observation instrument 200, referring to Figure 1 In this way, you can clearly see the dental floss and the gaps between the teeth, making it convenient to clean and treat the gaps between the teeth under direct vision, and observe the cleaning effect of the gaps between the teeth in real time.

[0075] In this embodiment, the connection 300 is an independent component. Figure 4 and Figure 4-1 The connecting mechanism 300 includes a slide bar 30, a positioning hook 31, a left positioning hook 31-1, a right positioning hook 31-2, a positioning convex step 32, and an anti-slip convex pattern 34; the positioning hook 31, the left positioning hook 31-1, and the right positioning hook 31-2 are arranged at the front end of the slide bar 30, the positioning hook 31 is in the middle, and the left positioning hook 31-1 and the right positioning hook 31-2 are arranged on both sides; the positioning convex step 32 is located in the middle of the slide bar 30; the anti-slip convex pattern 34 is arranged at the tail of the slide bar 30; the positioning convex step 32 is installed in the installation groove 21-2 of the housing 21 of the oral viewing instrument 200 The positioning convex step 21-3 of the housing 21 of the oral observation instrument 200 presses against the tail of the slide rod 30, and the connecting mechanism 300 is detachably mounted and fixed on the housing 21 of the oral observation instrument 200; the head 21-1 of the housing 21 of the oral observation instrument 200 is embedded in the through hole 13-1 of the mounting seat of the dental floss 100, and the positioning hook 31 of the connecting mechanism 300 is embedded in the positioning groove 13-2 of the mounting seat, and the left positioning hook 31-1 and the right positioning hook 31-2 embrace the head 21-1 of the housing 21 of the oral observation instrument 200 from the left and right sides.

[0076] refer to Figure 1 , Figure 2 During installation, first, the positioning convex step 32 of the connection mechanism 300 is embedded in the installation groove 21-2 of the housing 21 of the oral observation instrument 200, and the slide bar 30 of the connection mechanism 300 is slid forward until the positioning convex step 21-3 of the housing 21 of the oral observation instrument 200 bounces upward to support the tail of the slide bar 30. At this time, the left positioning hook 31-1 and the right positioning hook 31-2 embrace the head 21-1 of the housing 21 of the oral observation instrument 200 from both sides, and the connection mechanism 300 is installed and connected to the oral observation instrument 200. The anti-slip convex pattern 34 is provided on the tail of the slide bar 30 to increase friction and facilitate installation or removal of the connection mechanism 300. The combined effect of the embracing effect of the positioning convex step 21 - 3 and the left positioning hook 31 - 1 and the right positioning hook 31 - 2 and the concave-convex engagement of the positioning convex step 32 and the mounting groove 21 - 2 can effectively and firmly connect the connecting mechanism 300 to the oral viewing instrument 200 .

[0077] Then, the head 21-1 of the shell 21 of the oral viewing instrument 200 is embedded in the through hole 13-1 of the mounting seat of the dental floss 100, and the dental floss 100 is pushed toward the connecting mechanism 300, so that the positioning hook 31 of the connecting mechanism 300 is embedded in the positioning groove 13-2 of the mounting seat 13 to form a connection and fixation.

[0078] During disassembly, the top of the positioning hook 31 of the connecting mechanism 300 is pressed down, and the dental floss 100 is pulled outward to release the concave-convex engagement between the connecting mechanism 300 and the dental floss 100. When it is necessary to further remove the connecting mechanism 300 from the oral viewing instrument 200, the slide bar 30 is pulled back with force, the positioning convex step 21-3 of the oral viewing instrument 200 is pressed down, and the positioning convex step 32 of the connecting mechanism 300 is withdrawn from the mounting groove 21-2 of the embedded oral viewing instrument 200, until the connection between the connecting mechanism 300 and the oral viewing instrument 200 is completely released.

[0079] Since the positioning convex step 32 of the connecting mechanism 300 adopts an inverted T-shaped structure, when the T-shaped positioning convex step 32 is embedded in the mounting groove 21-2, the bottom of the inverted T-shaped structure can form a concave-convex card-fitting structure with the mounting groove 21-2, which can effectively limit the movement of the connecting mechanism 300 in the vertical direction, thereby preventing the connecting mechanism 300 and the oral viewing instrument 200 from detaching in the vertical direction during use. At the same time, the positioning convex step 21-3 of the oral observation instrument 200 is arranged at the rear end of the connecting mechanism 300. When the positioning convex step 21-3 of the oral observation instrument 200 is lifted upward, since the top position of the positioning convex step 21-3 is higher than the tail height of the connecting mechanism 300, the connecting mechanism 300 can be effectively prevented from retreating backward. Only when the connecting mechanism 300 is consciously retreated backward, the connecting mechanism 300 can be released from the oral observation instrument 200 after retreating along the guide surface of the positioning convex step 21-3, which can effectively prevent the dental floss 100 from accidentally loosening from the oral observation instrument 200 because the connecting mechanism 300 can easily retreat backward.
