Description

Technical Field

[0001] The invention relates to an oral cavity observation and cleaning tool, in particular to an oral cavity observation instrument for observing and cleaning tooth gaps. Background Art

[0002] Due to aging, pathological reasons and other reasons, it is easy to cause gum atrophy and widening of 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] To address this situation, oral observation and cleaning tools are currently available on the market. To address the poor visibility of existing cleaning tools, the applicant filed applications for a "built-in interdental brush" on March 12, 2014, with Chinese patent application number 201410091268.0; and a "visible interdental brush" on March 21, 2014, with Chinese patent application number 201410108525.7. These applications disclose a technical solution that combines an oral observation system with an oral cleaning tool.

[0004] However, oral observation systems are composed of various electronic components. If a large external electric field is applied, the electronic circuitry within the oral observation device can be easily damaged by static electricity generated by the external electric field unless it is properly protected. Furthermore, if the oral observation device is used in conjunction with an external cleaning tool, such as an interdental brush, this external electric field can be transmitted through the brush's metal core into the device, further damaging the electronic components.

[0005] Therefore, it is necessary to further provide electrostatic protection for the oral observation system in the existing technical solution to achieve electrostatic protection for the electronic components inside the oral observation instrument. Summary of the Invention

[0006] The anti-static oral observation instrument of the present invention is designed with a special electrostatic protection system, which can ensure that the anti-static oral observation instrument of the present invention has an electrostatic shielding effect on its internal electronic components when it is subjected to an external electric field, thereby avoiding accidental damage to the electronic components.

[0007] The anti-static oral observation instrument of the present invention is characterized in that: the anti-static oral observation instrument 200 includes a housing 4, a power supply system 5, a lighting system 6, an observation system 7, a circuit system 8, a switch 9 and an electrostatic protection system 400;

[0008] A. The lighting system 6, the observation system 7, and the power supply system 5 are installed in the housing 4, and the switch 9 is installed on the housing 4; the lighting system 6, the observation system 7, the power supply system 5, and the switch 9 are connected together through the circuit system 8;

[0009] B. The electrostatic protection system 400 includes a current guiding mechanism 40-1 and a grounding terminal 40-2. When the anti-static oral viewer 200 is subjected to an external electric field, the current guiding mechanism 40-1 can guide the external current acting on the anti-static oral viewer 200 to the grounding terminal 40-2 to achieve grounding, thereby providing electrostatic protection for the electronic components within the anti-static oral viewer 200.

[0010] The anti-static oral viewer of the present invention is designed with the electrostatic protection system 400. When the anti-static oral viewer of the present invention is subjected to an external electric field, the current guiding mechanism 40-1 of the electrostatic protection system 400 can guide the external current acting on the anti-static oral viewer 200 to the ground terminal 40-2 for grounding, thereby providing electrostatic shielding for the internal electronic components of the anti-static oral viewer, thereby preventing accidental damage to the internal electronic components of the anti-static oral viewer of the present invention under the action of the external electric field.

[0011] The grounding terminal 40-2 is grounded by electrostatic coupling. When the grounding terminal 40-2 is grounded by electrostatic coupling, the grounding terminal 40-2 can be set inside the housing without setting a grounding wire outside the housing, which makes the design and manufacturing process simpler and the use process safer.

[0012] The current guiding mechanism 40-1 is a linear current guiding mechanism 40-11, which is a guiding pin, a guiding rod, or a guiding wire. The linear current guiding mechanism 40-11 can quickly guide static electricity generated by an external electric field to the ground terminal 40-2, thereby achieving a high static shielding speed.

[0013] The current guiding mechanism 40-1 is a cover-shaped current guiding mechanism 40-12; the cover-shaped current guiding mechanism 40-12 is a guiding net, a guiding cover, or a guiding tube. The cover-shaped current guiding mechanism 40-12 can form a shielding net outside the electronic components to protect the electronic components over a wide range.

[0014] The anti-static oral viewer 200 is provided with an oral cleaning tool 201. The anti-static oral viewer 200 can be provided with the oral cleaning tool 201, and the oral cavity and teeth can be precisely cleaned using the oral cleaning tool 201 under direct observation of the anti-static oral viewer 200.

[0015] The oral cleaning tools 201 include an interdental brush 201-1, dental floss 201-2, a toothbrush 201-3, oral forceps 201-4, an oral scraper 201-5, an oral irrigator 201-6, and a flushable toothbrush 201-7. The applicant has only listed a few of the aforementioned oral cleaning tools. Those skilled in the art can design various oral cleaning tools for use with the electrostatic oral viewer 200 to clean the oral cavity and teeth, as needed. The applicant will not provide a comprehensive list of examples here, but these examples do not deviate from the scope of protection of this application.

[0016] The interdental brush 201-1 is a built-in interdental brush 100; the built-in interdental brush 100 includes an interdental brush 1 and a delivery device 2; the interdental brush 1 is movably built into the curved tube 21-1 at the front end of the delivery device 2. The built-in interdental brush 100 adopts a structure in which the interdental brush 1 is built into the curved tube 21-1 of the guide head 21 of the delivery device 2. After the working part 11 of the interdental brush 1 made of elastic material is aligned with the tooth gap by the guide head 21, the sliding mechanism 22 on the delivery device 2 is pushed to drive the working part 11 of the interdental brush 1 to automatically bend along the curvature of the curved tube 21-1, align with and enter the tooth gap, and push and pull the slider 22-2 on the sliding mechanism 22 of the delivery device 2 back and forth, so that the working part 11 of the interdental brush moves back and forth in the tooth gap to clean the tooth gap. Since the delivery device 2 has good rigidity, after the curved tube outlet 21-2 of the guide head 21 of the delivery device 2 is aligned with the tooth gap, the working part 11 of the interdental brush 1 is directly pushed into the tooth gap. Since the curved tube outlet 21-2 of the guide head 21 of the delivery device 2 is almost close to the tooth gap and very close to the tooth gap, the working part 11 of the interdental brush is not easy to bend, thereby greatly improving the force conductivity of the interdental brush 1 and the controllability of the interdental brush 1, thereby avoiding the shortcomings of the interdental brush in the prior art that it is easy to bend and easily damage the gums when cleaning the gaps between molars.

[0017] The housing 4 of the anti-static oral observer 200 is provided with a slide groove 41-2 for allowing the slider 22-2 of the built-in interdental brush 100 to move back and forth, and the slider 22-2 of the sliding mechanism 22 of the built-in interdental brush 100 includes an arched housing 22-2-1, and a guide block 22-2-2 is provided on the inner side of the arched housing 22-2-1; the guide block 22-2-2 can reciprocate in the slide groove 41-2 of the anti-static oral observer 200.

[0018] The anti-static oral observation instrument 200 is connected to the oral cleaning tool 201 via a connecting mechanism 300 .

[0019] The oral cleaning tool 201 is detachably mounted on the anti-static oral viewer 200 via the connecting mechanism 300 .

[0020] The oral cleaning tool 201 and the anti-static oral viewer 200 are flexibly assembled together via the connecting mechanism 300. They can be assembled together for single-handed operation to clean interdental spaces, or they can be disassembled so that one hand can hold the anti-static oral viewer 200 for observation while the other hand can hold the built-in interdental brush 100 for cleaning interdental spaces. This makes the tool easy to carry, quick to assemble, and flexible to use.

[0021] The connecting mechanism 300 is a detachable mechanical connecting mechanism, which can be an independent component or be provided on the oral cleaning tool 201 or the anti-static oral viewing instrument 200 .

[0022] The connecting mechanism 300 can be a separate component that connects to the oral cleaning tool 201 and the anti-static oral viewer 200, respectively, to form a single unit. The connecting mechanism 300 can also be manufactured as a single unit with the oral cleaning tool 201 or the oral viewer 200, and then connected to the anti-static oral viewer 200 or the oral cleaning tool 201 to form a single unit. Regardless of the connection method, the ultimate goal is to achieve a detachable connection between the oral cleaning tool 201 and the anti-static oral viewer 200. Therefore, the connecting mechanism 300 only needs to be able to achieve a detachable mechanical connection with either the oral cleaning tool 201 or the anti-static oral viewer 200 to achieve a detachable connection between the oral cleaning tool 201 and the anti-static oral viewer 200.

[0023] The mechanical connection mechanism may be a concave-convex snap-fit connection, a slot connection, a pin connection, a key connection, a threaded connection, a screw connection, a buckle connection, a hook connection, or an interference fit connection. Of course, those skilled in the art may choose other mechanical connection methods without departing from the scope of protection of this application.

[0024] The connecting mechanism 300 is disposed on the oral cleaning tool 201 , and the connecting mechanism 300 includes a positioning block 31 .

[0025] The housing 4 of the anti-static oral viewing instrument 200 is provided with a positioning groove 41 - 1 for fixing the connecting mechanism 300 .

[0026] The positioning block 31 can be embedded in the positioning groove 41 - 1 to connect the oral cleaning tool 201 to the anti-static oral viewing instrument 200 .

[0027] The positioning block 31 of the connecting mechanism 300 is an inverted T-shaped positioning block 31-1; the inverted T-shaped positioning block 31-1 is located below the connecting mechanism 300; the housing 4 of the anti-static oral viewer 200 is provided with a fixing mechanism 41, which includes a positioning slot 41-1, a slide slot 41-2, and a spring 41-3; the T-shaped positioning block 31-1 is detachably embedded in the positioning slot 41-1, and the upwardly springing spring 41-3 prevents the connecting mechanism 300 from retreating, thereby preventing the built-in interdental brush 100 from accidentally loosening from the anti-static oral viewer 200; the connecting mechanism 300 can be released from the anti-static oral viewer 200 by pressing the spring 41-3 downward and pulling the connecting mechanism 300 backward.

[0028] During installation, first fix the connecting mechanism 300 on the oral cleaning tool 201; push the connecting mechanism 300 forward, the inverted T-shaped positioning block 31-1 is embedded in the positioning groove 41-1, the spring piece 41-3 pops up, and the positioning block 31 is fixed in the positioning groove 41-1, and the oral cleaning tool 201 can be connected and fixed on the anti-static oral observer 200.

[0029] When the oral cleaning tool 201 needs to be removed, the connecting mechanism 300 is pulled back with force, the spring piece 41-3 is pressed down, the connecting mechanism 300 can be pulled back, and the inverted T-shaped positioning block 31-1 is withdrawn from the embedded positioning groove 41-1 until the connection between the T-shaped positioning block 31-1 and the positioning groove 41-1 is released. In this way, the oral cleaning tool 201 can be detached from the anti-static oral observer 200.

[0030] Since the inverted T-shaped positioning block 31-1 adopts an inverted T-shaped structure, when the T-shaped positioning block 31-1 is embedded in the positioning groove 41-1, the bottom of the inverted T-shaped structure can form a concave-convex card-fitting structure with the positioning groove 41-1, which can effectively limit the vertical movement of the connecting mechanism 300, thereby preventing the oral cleaning tool 201 and the anti-static oral observer 200 from detaching in the vertical direction during use. At the same time, the spring piece 41-3 is arranged at the rear end of the connecting mechanism 300. When the spring piece 41-3 is lifted upward, since the top position of the spring piece 41-3 is higher than the tail height of the connecting mechanism 300, the connecting mechanism 300 can be effectively prevented from retreating. Only by consciously and forcefully retreating the connecting mechanism 300 can the connecting mechanism 300 be withdrawn along the guide surface of the spring piece 41-3 and released from the anti-static oral observer 200. This can effectively prevent the oral cleaning tool 201 from accidentally loosening from the anti-static oral observer 200 because the connecting mechanism 300 can easily retreat.

[0031] The positioning block 31 of the connecting mechanism 300 is an arc-shaped positioning hook 31-2; the arc-shaped positioning hook 31-2 includes a positioning groove 31-2-1; the positioning groove 41-1 on the anti-static oral viewer 200 includes a positioning convex step 41-1-1 that matches the positioning groove 31-2-1; the arc-shaped positioning hook 31-2 is embedded in the positioning groove 41-1 to form a concave-convex fit, thereby limiting the vertical movement of the connecting mechanism 300; the positioning convex step 41-1-1 is embedded in the positioning groove 31-2-1, thereby limiting the forward and backward movement of the connecting mechanism 300.

[0032] During installation, align the arc-shaped positioning hook 31-2 of the connecting mechanism 300 with the positioning groove 41-1 on the housing 4 of the anti-static oral viewer 200; press down the oral cleaning tool 201 and the connecting mechanism 300, and insert the arc-shaped positioning hook 31-2 of the connecting mechanism 300 into the positioning groove 41-1 to form a concave-convex snap fit, thereby limiting the vertical movement of the connecting mechanism 300; slide the connecting mechanism 300 forward until the positioning convex step 41-1-1 of the anti-static oral viewer 200 is inserted into the positioning groove 31-2-1 of the connecting mechanism 300, thereby limiting the forward and backward movement of the connecting mechanism 300. When the oral cleaning tool 201 needs to be removed, the connecting mechanism 300 is pulled back with force, and the positioning groove 31-2-1 of the connecting mechanism 300 is released from the positioning convex step 41-1-1 of the anti-static oral viewer 200; the connecting mechanism 300 is further slid backward along the positioning groove 41-1 of the anti-static oral viewer 200, and the connecting mechanism 300 can be released from the anti-static oral viewer 200.

[0033] The double concave-convex fitting connection formed by the arc-shaped positioning hook 31-2 and the positioning groove 41-1, the positioning convex step 41-1-1 and the positioning groove 31-2-1 can achieve effective connection and fixation of the connecting mechanism 300 and the anti-static oral viewing instrument 200.

[0034] The observation system 7 is a camera system 7 - 1 , which includes a camera head 7 - 1 - 1 , a data processing and output system 7 - 1 - 2 , a circuit system 8 and a power supply system 5 .

[0035] The camera 7-1-1 can observe the situation inside the oral cavity, especially the cleaning process in real time, making the cleaning process more convenient and safer.

[0036] The video data output by the data processing and output system 7-1-2 of the camera system 7-1 can be displayed on the display 7-1-3 through a wired connection or a wireless connection. The display 7-1-3 includes: a smartphone 7-1-31, a computer 7-1-32, a liquid crystal display 7-1-33, or a television 7-1-34.

[0037] A lighting system 6 is provided around the camera 7-1-1. The lighting system 6 is provided around the camera 7-1-1 and can directly illuminate the camera 7-1-1, thereby better ensuring the shooting effect of the camera 7-1-1.

[0038] The anti-static oral viewer 200 of the present invention comprises a housing 4, a power supply system 5, an illumination system 6, an observation system 7, a circuit system 8, a switch 9, and an electrostatic protection system 400. The electrostatic protection system 400 comprises a current guiding mechanism 40-1 and a grounding terminal 40-2. When the anti-static oral viewer 200 is subjected to an external electric field, the current guiding mechanism 40-1 can guide the external current to the grounding terminal 40-2, thereby grounding the electronic components within the anti-static oral viewer 200. This provides electrostatic protection for the electronic components within the anti-static oral viewer 200 and ensures safe use of the anti-static oral viewer 200. The anti-static oral viewer of the present invention can be connected to the oral cleaning tool 201 via the connecting mechanism 300. Under real-time observation by the camera 7-1-1, the oral cleaning tool 201 can be used to clean the oral cavity, enabling real-time observation and targeted cleaning of the oral cavity, making it very convenient to use.

The built-in interdental brush 100 comprises an interdental brush 1 and a delivery device 2; the interdental brush 1 is movably built into a curved tube 21-1 at the front end of the delivery device 2.

[0099] The interdental brush 1 of the built-in interdental brush 100 comprises a working part 11 and a connecting body 12; the working part 11 is arranged at the front end of the connecting body 12; the delivery device 2 comprises a guide head 21 and a sliding mechanism 22; the guide head 21 is arranged on the front end 2-1 of the delivery device 2; the guide head 21 contains a curved tube 21-1, and the outlet 21-2 of the curved tube 21-1 is arranged at the end 21-3 of the guide head 21; the interdental brush 1 is installed in the curved tube 21-1, and the working part 11 of the interdental brush 1 can slide in the curved tube 21-1, and the connecting body 12 of the interdental brush 1 is installed on the sliding mechanism 22 of the delivery device 2; the movement of the sliding mechanism 22 can drive the working part 11 of the interdental brush 1 to slide in the curved tube 21-1; driving the sliding mechanism 22 can make the working part 11 of the interdental brush 1 extend from the outlet 21-2 of the curved tube at the end of the guide head, Figures 2 to 2-9 .

[0101] The housing 4 of the anti-static oral observer 200 is provided with a slide groove 41-2 for allowing the slider 22-2 of the built-in interdental brush 100 to move back and forth, and the slider 22-2 of the sliding mechanism 22 of the built-in interdental brush 100 includes an arched housing 22-2-1, and a guide block 22-2-2 is provided on the inner side of the arched housing 22-2-1; the guide block 22-2-2 can reciprocate in the slide groove 41-2 of the anti-static oral observer 200.

[0102] The built-in interdental brush 100 adopts a structure in which the interdental brush 1 is built into the curved tube 21-1 of the guide head 21 of the delivery device 2. After the working part 11 of the interdental brush 1 made of elastic material is aligned with the tooth gap by the guide head 21, the sliding mechanism 22 on the delivery device 2 is pushed to drive the working part 11 of the interdental brush 1 to automatically bend along the curvature of the curved tube 21-1, align with and enter the tooth gap. By pushing and pulling the slider 22-2 on the sliding mechanism 22 of the delivery device 2 back and forth, the working part 11 of the interdental brush moves back and forth in the tooth gap to clean the tooth gap. Since the delivery device 2 has good rigidity, after the curved tube outlet 21-2 of the guide head 21 of the delivery device 2 is aligned with the tooth gap, the working part 11 of the interdental brush 1 is directly pushed into the tooth gap. Since the curved tube outlet 21-2 of the guide head 21 of the delivery device 2 is almost close to the tooth gap and very close to the tooth gap, the working part 11 of the interdental brush is not easy to bend, thereby greatly improving the force conductivity of the interdental brush 1 and the controllability of the interdental brush 1, thereby avoiding the shortcomings of the interdental brush in the prior art that it is easy to bend and easily damage the gums when cleaning the gaps between molars.

[0103] The anti-static oral observation instrument 200 is connected to the oral cleaning tool 201 via a connecting mechanism 300 .

[0104] In this embodiment, the oral cleaning tool 201 is detachably mounted on the anti-static oral viewer 200 via the connecting mechanism 300 .

[0105] The oral cleaning tool 201 and the anti-static oral viewer 200 are flexibly assembled together via the connecting mechanism 300. They can be assembled together for single-handed operation to clean interdental spaces, or they can be disassembled so that one hand can hold the anti-static oral viewer 200 for observation while the other hand can hold the built-in interdental brush 100 for cleaning interdental spaces. This makes the tool easy to carry, quick to assemble, and flexible to use.

[0106] The mechanical connection mechanism may be a concave-convex snap-fit connection, a slot connection, a pin connection, a key connection, a threaded connection, a screw connection, a buckle connection, a hook connection, or an interference fit connection. Of course, those skilled in the art may choose other mechanical connection methods without departing from the scope of protection of this application.

[0107] The connecting mechanism 300 can be a separate component or can be provided on the oral cleaning tool 201 or the anti-static oral viewer 200. In this embodiment, the connecting mechanism 300 is provided on the guide head 21 of the built-in interdental brush 100 and is connected to the guide head 21 of the built-in interdental brush 100 by being integrally manufactured; the connecting mechanism 300 includes a positioning block 31.

[0108] The connecting mechanism 300 can also be a separate component, connected to the oral cleaning tool 201 and the anti-static oral viewer 200, respectively, to connect the oral cleaning tool 201 and the anti-static oral viewer 200 into a single unit. The connecting mechanism 300 can also be manufactured as a single unit with the oral cleaning tool 201 or the oral viewer 200, and then connected to the anti-static oral viewer 200 or the oral cleaning tool 201 to form a single unit. Regardless of the connection method, the ultimate goal is to achieve a detachable connection between the oral cleaning tool 201 and the anti-static oral viewer 200. Therefore, the connecting mechanism 300 only needs to be able to achieve a detachable mechanical connection with either the oral cleaning tool 201 or the anti-static oral viewer 200 to achieve a detachable connection between the oral cleaning tool 201 and the anti-static oral viewer 200.

[0109] The housing 4 of the anti-static oral viewing instrument 200 is provided with a positioning groove 41 - 1 for fixing the connecting mechanism 300 .

[0110] The positioning block 31 can be embedded in the positioning groove 41 - 1 , and the connecting mechanism 300 connects the oral cleaning tool 201 to the anti-static oral viewing instrument 200 through a concave-convex snap fit.

[0111] In this embodiment, the positioning block 31 of the connecting mechanism 300 is an inverted T-shaped positioning block 31-1; the inverted T-shaped positioning block 31-1 is located below the connecting mechanism 300; the housing 4 of the anti-static oral viewer 200 is provided with a fixing mechanism 41, the fixing mechanism 41 including a positioning slot 41-1, a slide slot 41-2, and a spring 41-3; the T-shaped positioning block 31-1 is detachably embedded in the positioning slot 41-1, and the upwardly springing spring 41-3 can prevent the connecting mechanism 300 from retreating, thereby preventing the built-in interdental brush 100 from accidentally loosening from the anti-static oral viewer 200; the connecting mechanism 300 can be released from the anti-static oral viewer 200 by pressing the spring 41-3 downward and pulling the connecting mechanism 300 backward at the same time.

[0112] During installation, first fix the connecting mechanism 300 at an appropriate position on the guide head 21 of the delivery device 2 of the built-in interdental brush 100; then connect the interdental brush 1 of the built-in interdental brush 100 and the slider 22-2 of the delivery device 2; then install the interdental brush 1 in the curved tube 21-1 of the guide head 21 of the delivery device 2; push the slider 22-2 forward, and bring the connecting mechanism 300 and the slider 22-2 of the built-in interdental brush 100 together.

[0113] Then, the built-in interdental brush 100 and the connecting mechanism 300 are fitted downwardly onto the fixing mechanism 41 on the housing 4 of the anti-static oral viewer 200 along the positioning end 42 of the housing 4 of the anti-static oral viewer 200; the built-in interdental brush 100 and the connecting mechanism 300 are pressed downward, and the guide block 22-2-2 on the inner side of the arched housing 22-2-1 of the slider 22-2 of the built-in interdental brush 100 is embedded in the slide groove 41-2 of the anti-static oral viewer 200; at the same time, the spring piece 41-3 is pressed down, and the inverted T-shaped positioning block 31-1 enters the positioning groove 41-1 of the anti-static oral viewer 200.

[0114] Keeping the slider 22-2 and the interdental brush 1 of the built-in interdental brush 100 stationary, push the connecting mechanism 300 forward so that the inverted T-shaped positioning block 31-1 of the connecting mechanism 300 is embedded in the positioning groove 41-1 of the anti-static oral observer 200 until the spring 41-3 bounces upward and presses against the rear end of the connecting mechanism 300, thus installing the connecting mechanism 300 in place and establishing a firm connection between the built-in interdental brush 100 and the anti-static oral observer 200.

[0115] When the built-in interdental brush 100 needs to be removed, the connecting mechanism 300 is moved backward with force, the spring piece 41-3 is pressed down, the connecting mechanism 300 can move backward, and the inverted T-shaped positioning block 31-1 is withdrawn from the embedded positioning groove 41-1 until the connection between the T-shaped positioning block 31-1 and the positioning groove 41-1 is released. In this way, the built-in interdental brush 100 can be detached from the anti-static oral observer 200.

[0116] Since the inverted T-shaped positioning block 31-1 adopts an inverted T-shaped structure, when the T-shaped positioning block 31-1 is embedded in the positioning groove 41-1, the bottom of the inverted T-shaped structure can form a concave-convex card-fitting structure with the positioning groove 41-1, which can effectively limit the vertical movement of the connecting mechanism 300, thereby preventing the oral cleaning tool 201 and the anti-static oral observer 200 from detaching in the vertical direction during use. At the same time, the spring piece 41-3 is arranged at the rear end of the connecting mechanism 300. When the spring piece 41-3 is lifted upward, since the top position of the spring piece 41-3 is higher than the tail height of the connecting mechanism 300, the connecting mechanism 300 can be effectively prevented from retreating. Only by consciously and forcefully retreating the connecting mechanism 300 can the connecting mechanism 300 be withdrawn along the guide surface of the spring piece 41-3 and released from the anti-static oral observer 200. This can effectively prevent the oral cleaning tool 201 from accidentally loosening from the anti-static oral observer 200 because the connecting mechanism 300 can easily retreat.

[0117] refer to Figure 1-3 and Figure 1-5 In this embodiment, since the oral cleaning tool 201 is a built-in interdental brush 100, the axis of the working part 11 of the interdental brush 1 of the built-in interdental brush 100 and the guide head 21 of the delivery device 2 are made of metal to ensure their strength. Therefore, in order to prevent the external electric field from damaging the internal electronic components of the anti-static oral observer 200 of the present invention through the built-in interdental brush 100, a linear current guiding mechanism 40-11 is designed under the built-in interdental brush 100. The linear current guiding mechanism 40-11 is a guiding pin. The linear current guiding mechanism 40-11 can quickly guide the static electricity generated by the external electric field to the grounding terminal 40-2 located near the bottom of the shell 4 to achieve electrostatic shielding.

[0118] The linear current guiding mechanism 40 - 11 may also be a guiding rod, a guiding wire or other guiding structures. The applicant does not give specific examples here, but they do not deviate from the protection scope of this application.

[0119] refer to Figures 1-2 to 1-4 In this embodiment, the power supply system 5 is a rechargeable battery 51, which can be charged through a charging port 51-1. To prevent the external electric field from accidentally damaging the internal electronic components through the charging port 51-1, a cover-shaped current guiding mechanism 40-12 is provided outside the battery 51 and electronic components. In this embodiment, the cover-shaped current guiding mechanism 40-12 is a metal guide cover. The current generated by the external electric field is guided through the metal guide cover to the ground terminal 40-2 located below the housing 4. The cover-shaped current guiding mechanism 40-12 can form a shielding net outside the electronic components, providing overall protection for the electronic component assembly.

[0120] The cover-shaped current guiding mechanism 40 - 12 can be designed into various structures such as a guiding net or a tubular guiding tube as needed. The applicant will not give examples one by one here, but they all do not depart from the scope of protection of this application.

[0121] Figures 1 to 1-3 In this embodiment, the observation system 7 is a camera system 7-1, and the camera system 7-1 includes a camera 7-1-1, a data processing and output system 7-1-2, a circuit system 8 and a power supply system 5.

[0122] The camera 7-1-1 can observe the situation inside the oral cavity, especially the cleaning process in real time, making the cleaning process more convenient and safer.

[0123] refer to Figure 9 and Figure 10The video data output by the data processing and output system 7-1-2 of the camera system 7-1 can be displayed on the display 7-1-3 through a wired connection or a wireless connection. The display 7-1-3 includes: a smart phone 7-1-31, or a computer 7-1-32, or a liquid crystal display 7-1-33, or a TV 7-1-34.

[0124] In this embodiment, a lighting system 6 is provided around the camera 7-1-1. The lighting system 6 is provided around the camera 7-1-1 and can directly illuminate the camera 7-1-1, thereby better ensuring the shooting effect of the camera 7-1-1.

[0125] Because the anti-static oral viewer of this embodiment is designed with the electrostatic protection system 400, when the anti-static oral viewer of the present invention is subjected to an external electric field, the current guiding mechanism 40-1 of the electrostatic protection system 400 can guide the external current acting on the anti-static oral viewer 200 to the ground terminal 40-2, thereby providing electrostatic shielding for the internal electronic components of the anti-static oral viewer, thereby preventing accidental damage to the internal electronic components of the anti-static oral viewer of the present invention under the influence of the external electric field. Furthermore, the current guiding mechanism 40-1 can be designed as a linear current guiding mechanism 40-11 or a cover-shaped current guiding mechanism 40-12, providing comprehensive protection for the electronic components within the anti-static oral viewer of this embodiment.

[0126] The anti-static oral observation instrument of this embodiment can also be connected to various oral cleaning tools 201 such as the built-in interdental brush 100 through the connecting mechanism 300. Under the real-time observation of the camera 7-1-1, the oral cavity is cleaned using the oral cleaning tool 201, thereby realizing real-time observation and fixed-point cleaning of oral cleaning, and the use process is very convenient.

[0127] Example 2: Anti-static oral observation instrument of the present invention with arc-shaped positioning hook-type positioning block

[0128] refer to Figures 2-5 to 2-7 The difference between this embodiment and embodiment 1 is that the positioning block 31 of the connecting mechanism 300 in this embodiment adopts an arc-shaped positioning hook 31-2.

[0129] The arc-shaped positioning hook 31-2 includes a positioning groove 31-2-1. The positioning groove 41-1 on the anti-static oral observation instrument 200 includes a positioning convex step 41-1-1 that matches the positioning groove 31-2-1. The arc-shaped positioning hook 31-2 is embedded in the positioning groove 41-1 to form a concave-convex card fit, which limits the vertical movement of the connecting mechanism 300. Figure 9 、 Figure 9-1The positioning convex step 41-1-1 is embedded in the positioning groove 31-2-1, limiting the forward and backward movement of the connecting mechanism 300, reference Figures 2-5 to 2-7 .

[0130] During installation, after the built-in interdental brush 100 and the connecting mechanism 300 are installed as described above, align the slider 22-2 of the built-in interdental brush 100 with the slide groove 41-2 on the housing 4 of the anti-static oral observer 200, and align the arc-shaped positioning hook 31-2 of the connecting mechanism 300 with the positioning groove 41-1 on the housing 4 of the anti-static oral observer 200; press down the built-in interdental brush 100 and the connecting mechanism 300, and align the arched housing 22-2-1 of the slider 22-2 of the built-in interdental brush 100. The inner guide block 22-2-2 is embedded in the slide groove 41-2 of the anti-static oral observation instrument 200; the arc-shaped positioning hook 31-2 of the connecting mechanism 300 is embedded in the positioning groove 41-1 to form a concave-convex card fit to limit the vertical movement of the connecting mechanism 300; the connecting mechanism 300 is slid forward until the positioning convex step 41-1-1 of the anti-static oral observation instrument 200 is embedded in the positioning groove 31-2-1 of the connecting mechanism 300, thereby limiting the forward and backward movement of the connecting mechanism 300. When the built-in interdental brush 100 needs to be removed, the connecting mechanism 300 is pulled back with force, and the positioning groove 31-2-1 of the connecting mechanism 300 is released from the positioning convex step 41-1-1 of the anti-static oral viewer 200; the connecting mechanism 300 is further slid backward along the positioning groove 41-1 of the anti-static oral viewer 200, and the connecting mechanism 300 can be released from the anti-static oral viewer 200.

[0131] Compared with Example 1, in this embodiment, the double concave-convex card-fit connection formed by the arc-shaped positioning hook 31-2 and the positioning groove 41-1, and the positioning convex step 41-1-1 and the positioning groove 31-2-1 can realize the effective connection and fixation of the connecting mechanism 300 and the anti-static oral observer 200.

[0132] In addition to the connection method of the positioning block and the positioning hook specifically illustrated by the applicant in the aforementioned embodiment, the connecting mechanism 300 can also be designed into various other connection methods such as connecting rings and connecting holes as needed. The applicant will not give examples one by one here, but they do not deviate from the scope of protection of this application.

[0133] It should be noted that the structures disclosed and described herein may be replaced by other structures with equivalent effects, and the embodiments described herein are not the only structures for implementing the present invention. Although preferred embodiments of the present invention have been described and illustrated herein, those skilled in the art will readily appreciate that these embodiments are merely illustrative and that numerous variations, modifications, and substitutions may be made by those skilled in the art without departing from the present invention. Therefore, the scope of protection of the present invention should be defined in accordance with the spirit and scope of the appended claims.
